    During the period from May to August, 1984, an epidemic of infectious disease with echovirus type 16 occurred in Tono area of southeast in Gifu prefecture. This virus caused children to have different clinical symptoms, one was a exanthem disease and another was aseptic meningitis. These cases confirmed by virological and serological methods were 48 cases, that is, patients with aseptic meningitis were 24 cases and patients with exanthem disease were 24 cases. By serological examination of antibody against echovirus type 16, it was confirmed that this virus type invaded Gifu Prefecture before 1984.

    The groundwater flow analysis involve the groundwater recharge from the subsurface to the rock mass. According to water balance method, annual groundwater recharge is calculated by the remainder of annual evapotranspirator and river flow from annual precipitation. In this estimation, hydrological and meteorological data observed for 5 years on the watershed in Tono mine area is used. Annual precipitation ranges from 1,000 to 1,900 mm and annual river flow ranges from 400 to 1,300 mm, then river flow depends critically on precipitation. Annual evapotranspiration calculated by Penman method ranges from 400 to 500 mm. It is less fluctuant than annual precipitation. As the result of examination of water balance in subsurface zone estimated, annual ground water recharge ranges from 10 to 200 mm in this watershed. (author)

    2012-01-01

    This paper discusses the effectiveness of a woody biomass utilization system that would result in increased net energy production through wood pellet production, along with energy recovery processes as they relate to household energy demand. The direct environmental load of the system, including wood pellet production and utilization processes, was evaluated. Furthermore, the indirect load, including the economic impact of converting the existing fossil-fuel-based energy system into a woody biomass-based system, on the entire society was also evaluated. Gifu Prefecture in Japan was selected for a case study, which included a comparative evaluation of the environmental load and costs both with and without coordination with the wood pellet production process and the waste-to-energy of municipal solid waste process, using the life cycle assessment methodology. If the release of greenhouse gases from the combustion of wood pellets is included in calculations, then burning wood pellets results in unfavorable environmental consequences. However, when the reduced indirect environmental load due to the utilization of wood pellets versus petroleum is included in calculations, then favorable environmental consequences result, with a net reduction of greenhouse gases emissions by 14,060 ton-CO 2eq . -- Highlights: ► We evaluate economic and environmental impact of woody biomass utilization in household. ► Wood pellet utilization for house heating is advantageous to reduce greenhouse gas emissions. ► Reduction effect of greenhouse gas will be canceled out if carbon neutrality were considered. ► Net greenhouse gas emissions considering conversion of an ordinal energy system will be minus. ► Wood pellet utilization is advantageous not only in global warming but also for resource conservation.

    The road slope hazard, which is the occurrence rate of rock falls along the major road, in Hida region, consists of Takayama, Furukawa and Gero areas, is evaluated in this paper. This rock fall rate is estimated in two folds. First, the relative rate of lock falls is estimated by the Logit regression analysis based on the inventory data of slops along the major roads in the region which includes about 3000 slopes. The inventory data include topological, geological and geotechnical characteristics of each slope evaluated by the experts in 1996. The slopes are also classified into three categories by the experts as "measures required', "continuous observation" and "no measures required". Based on this classification, the logit regression analyses are carried out to rank the hazard of the slopes by their attributed characteristics as the explanatory variables. Once relative rate of lock falls are estimated for each slope, this rate is calibrated to the absolute rate by using the actual rock fall event records between 2004 and 2008. By these two folds estimation procedure, the absolute rate of rock fall for each slope along the roads are finally esti-mated. This study is a part of the infrastructure asset management strategy decision making program based on risk, and the information gained in this study is combined with other evaluation data for damage to propose the strategy for repair and maintenance plan of the road slopes in this region.

    The hydrothermal water balance of the Yakedake volcano and the vicinity is considered quantitatively. From the observed results of boreholes, the thermal and geological structures of the Karukaya and Takara geothermal areas are also presented. The hydrothermal activity is intense in the western half on the base of the volcano and the Nakanoyu area. The total hot water flow from the discharge area (high temperature zone; Shinhodaka and others) amounts to 2.07*10/sup 4/ l/min, about 60 percent of the hot water discharges from the Shinhodaka area. There are some large basins (Abodaira and others) in which the rocks are mainly volcanic tuff and pumice showing very high permeability for water. The total area of the water recharge zone amounts to 18.2*10/sup 6/m/sup 2/. The ratio of the total hot spring water volume to the total precipitation in the recharge area is 0.21. The cold water is permeated in the basins and, in the deep depth of the volcano, is heated by the thermal energy from the magma reservoir and the hot water is flowed through a fractured zone to the ground-surface as natural hot springs in the discharge area. The results from three deep boreholes give thermal conductivity of core samples ranging from 3.81 to 4.09 w m/sup -1//degree/C/sup -1/ in the Karukaya and Takara areas. The corresponding surface heat flows by vertical heat conduction become 2.35 and 1.86 w/m/sup 2/ in the Karukaya and the Takara areas, respectively. Refs.

    We have measured environmental radiation dose rates in several Prefectures, such as Ai chi Prefecture, Gifu Prefecture, and Mie Prefecture, in central Japan. Recently, we measured the environmental radiation dose rates in Kyoto and Shiga Prefectures that are also located in central Japan with a car-borne survey system. At the time of measurement, Kyoto Prefecture (area: 4,613 km 2 ) had a total of 36 districts, and Shiga Prefecture (area: 3,387 km 2 ) a total of 26. Terrestrial gamma ray dose rates and secondary cosmic ray dose rates were measured by a 2 inches ψ x 2 inches NaI(Tl) scintillation counter and a handy-type altimeter (GPS eTrex Legend by Gamin), respectively. The following factors were taken into consideration the shielding effect of the car body, the effect of the road pavement, radon progeny borne by precipitation, and increases in tunnels and near the walls. Terrestrial gamma ray dose rates in Kyoto and Shiga Prefectures were estimated to be 51.7 ± 6.0 n Gy/h (district average: 52.4 ± 4.7 n Gy/h), 52.2 ± 10.5 n Gy/h (district average: 51.9 ± 8.1 n Gy/h), respectively. Secondary cosmic ray dose rates in Kyoto and Shiga Prefectures were 30.0 ± 0.6 n Gy/h (district average: 29.9 ±0.3 n Gy/h), 30.1 ± 0.3 n Gy/h (district average: 30.0 ± 0.2 n Gy/h), respectively. The environmental radiation dose rates due to the sum dose rates of terrestrial gamma ray and secondary cosmic ray in Kyoto and Shiga Prefectures were 81.7 ± 6.2 n Gy/h (district average: 82.3 ± 4.8 n Gy/h), 82.3 ± 10.6 n Gy/h (district average: 82.0 ± 8.1 n Gy/h), respectively. We confirmed that the environmental radiation dose rates in Kyoto and Shiga Prefectures mainly depended on the change of the terrestrial gamma ray dose rates, since the secondary cosmic ray dose rates had little change. Therefore, radiation dose-rate maps of the terrestrial gamma rays as well as maps of the environmental radiation dose-rate were drawn. (author)

    Dehong Prefecture in Yunnan Province, China, borders Myanmar. Its proximity to the 'Golden Triangle', one of the world's largest illicit drug production and distribution centre, contributes to drug trafficking and ready availability of heroin. Dehong's 1.1 million people confront a serious HIV problem fuelled by injection drug use. The aim of this study is to improve the 2005 estimates of the true status of the HIV/AIDS epidemic in Dehong Prefecture. We estimated the HIV prevalence by synthesizing the results from several data sources (HIV/AIDS case reports, surveys, surveillance activities and epidemiological studies). We applied three different statistical procedures for estimations: (i) The Workbook method, adapted to meet the estimation needs in Dehong Prefecture; (ii) An estimate based on antenatal clinical data; and (iii) a dynamic model based on the local epidemic pattern. We estimated that the population prevalence for HIV infections in Dehong Prefecture is 1.3% (likely range from low/high of three estimates: 0.9-1.7%) such that 13 500 people were living with HIV/AIDS in Dehong Prefecture (likely range: 8,200-18,300) in 2005. Infections remain concentrated among injection drug users, female sex workers and their clients with an uneven geographical distribution of estimated cases. More reliable estimates of HIV prevalence can be made by synthesizing multiple data sources using several procedures. Current HIV prevention, care and treatment challenges are judged substantial in Dehong Prefecture, regardless of what modelling strategy is used.

    We investigated 14 C specific activity of farm products and marine products which were collected from the Rokkasho area in Aomori prefecture from 1988 to 1990. The measured 14 C specific activity of farm products was almost equal to one another with the averaged 14 C specific activity of 0.261 [Bq/g·C]. On the other hand, 14 C specific activity of marine products was slightly lower than those of farm products. Especially that of squid was the lowest among studied marine products. This may be due to the low 14 C specific activity of the sea water surrounding squid. (author)

    Seismic reflection survey was performed for the Medial Tectonic Line, an important geological tectonic line in the Kanto plains, at Kushibiki district, Saitama prefecture in the north-western part of the Kanto plains. It was estimated that movements of the basement were different in the individual sides of the active fault. In this study, the seismic reflection survey was performed at the Omama fan area, Gunma prefecture, which is located at the north-eastern extension of the Kushibiki plateau, to grasp the structure of basement to the depth of about 1.0 s of return travel time, and the upper sediments. Two traverse lines passing Ota city, Kiryu city, and Nitta town were used. Southern part of the traverse line-1 was in the bottom land in the middle of Tone river, and northern part was in the Omama fan area. The ground surface along the traverse line was flat. Hachioji heights are the heights elongating in the NW-SE direction and having relative height of 100 to 200 m against the surrounding plain. Another traverse line-2 was set on the steep slope having relative height more than 100 m. The Brute stack time section of each traverse line was characterized by the gradient reflection surface AA of the traverse line-1. It was suggested that the AA or intermittent parts of reflection surfaces deeper than AA may relate to the tectonic lines in the more ancient geological ages. 2 figs., 1 tab.

    In the safety assessment for a geological disposal of long-lived radioactive waste such as high-level radioactive waste and TRU waste etc, it is important to estimate radionuclide migration to human society associated with groundwater flow. Groundwater flow systems for many domestic areas including Tono Mine, Kamaishi Mine and Horonobe district have been studied, but deep groundwater flow circumstances, and mixing between deep groundwater and shallow groundwater flow system are not well understood. Japan Atomic Energy Agency (JAEA) has started to investigate a sedimentary rock area in the Yoro river basin, in Chiba Prefecture, where the topographic and geological features are relatively simple for mathematical modeling, and hydraulic data as well as data from river and well water are available. Hydro-chemical conditions of the regional groundwater were discussed based on temperature, chemical compositions, isotopic ratios of hydrogen and oxygen, and the isotopic age of radioactive carbon for water samples collected from wells, rivers and springs in the Yoro river basin. It was found that the groundwater system in this basin consists of types of water: Ca-HCO 3 type water, Na-HCO 3 type water and NaCl type water. The Ca-HCO 3 type water is meteoric water cultivated several thousand years or after, the Na-HCO 3 type water is meteoric water cultivated under cold climates several to twenty thousand years ago. The NaCl type water is fossil brine water formed twenty thousand years ago. It was also observed that the Na-HCO 3 type water upwelled at the surface originates from GL-200m to -400m. This observation indicates that the Na-HCO 3 type water upwelled through the Ca-HCO 3 type water area with the both waters partially mixed. (author)

    The consumption of eight categories of marine foods was surveyed on two kinds of families in Oarai town, one of the famous fishing towns in Ibaraki prefecture. The average daily intake of whole marine foods through a year of 1973 was 255 g/d/p for fisherman's families and 166 g/d/p for nonfisherman's, respectively. Fisherman's families showed higher consumption of all categories of marine foods except algae than non-fisherman's. Seasonal variation of marine food consumption was observed for both families, i.e., the consumption in spring was less than that in the other seasons. One half of the total marine foods consumption was occupied by fishes. And among three kinds of fishes, high consumption of pelagic fish was recognized. These consumption aspects were almost similar to those observed in Kuji, Tokai and Nakaminato as reported previously. (auth.)

    The clinical professors at Gifu Pharmaceutical University (GPU) provide pharmaceutical services at GPU Pharmacy, Gifu University Hospital, and Gifu Municipal Hospital to keep their clinical skills up-to-date; they also perform clinical research in collaboration with many clinical institutes. The Laboratory of Clinical Pharmacy is part of the Department of Pharmacy Practice and Science, to which the clinical professors belong, and is composed of three clinical professors (a professor, an associate professor, and an assistant professor). The professor administers the GPU Pharmacy as its director, while the associate professor and assistant professor provide pharmaceutical services to patients at Gifu Municipal Hospital, and also provide practical training for students in the GPU Pharmacy. Collectively, they have performed research on such topics as medication education for students, clinical communication education, and analysis of clinical big data. They have also conducted research in collaboration with clinical institutes, hospitals, and pharmacies. Here, we introduce the collaborative research between the Laboratory of Clinical Pharmacy and Gifu Municipal Hospital. These studies include "Risk factors contributing to urinary protein expression resulting from bevacizumab combination chemotherapy", "Hyponatremia and hypokalemia as risk factors for falls", "Economic evaluation of adjustments of levofloxacin dosage by dispensing pharmacists for patients with renal dysfunction", and "Effect of patient education upon discharge for use of a medication notebook on purchasing over-the-counter drugs and health foods". In this symposium, we would like to demonstrate one model of the association and collaborative research between these clinical professors and clinical institutes.

    We aimed to clarify the correlation between the 2011 Great East Japan Earthquake and pregnant women's awareness of social capital 3 to 9 months after the tsunami disaster. We analyzed data on responses to a questionnaire by 7451 pregnant women in their second to third trimesters. The proportions of social capital-related items were calculated in the north and south coastal areas of Miyagi Prefecture and were compared with national samples. The factors associated with social capital were estimated by use of multivariate logistic regression analyses. The proportion of women feeling that they had helpful neighbors was higher (69.0% vs 56.7%, P=0.0005), the proportion of women regarding their communities as safe and secure was lower (51.7% vs 62.4%, P=0.002), and the proportion of women feeling that most people were trustworthy was lower (23.7% vs 32.9%, P=0.006) in the north coastal area than nationwide. Such differences were not observed in the less severely affected south coastal area. Age of 35 years or older, extended family, college or university graduation, and being multiparous were associated with the feeling of having helpful neighbors. The current status of pregnant women's awareness of social capital in disaster-affected areas was revealed. Continuous monitoring and support may be necessary to address this issue.(Disaster Med Public Health Preparedness. 2017;11:355-364).

    2017-12-01

    Continuous long-term observations of ambient noise (microseisms) were performed from August 2014 to February 2017 in the Beppu-Bay area, Oita prefecture, to investigate S-wave velocity structure of deep sedimentary basin (Hayashida et al., 2015SSJ; Yoshimi and Hayashida, 2017WCEE). The observation array consists of 12 broadband stations with an average spacing of 12 km. We applied the seismic interferometry technique to the ambient noise data and derived nine-component ambient noise cross-correlation functions (Z-R, Z-T, Z-Z, R-R, R-T, R-Z, T-R, T-T, and T-Z components) between 66 pairs of stations (distance of 6.4 km to 65.2 km). We assumed the stacked cross-correlation functions as "observed Green's functions" between two stations and estimated group velocities of Rayleigh and Love waves in the frequency between 0.2 and 0.5 Hz (Hayashida et al., 2017AGU-JpGU). Theoretical Green's functions for all stations pairs were also calculated using the finite difference method (HOT-FDM, Nakamura et al., 2012BSSA), with an existing three-dimensional basin structure model (J-SHIS V2) with land and seafloor topography and a seawater layer (Okunaka et al., 2016JpGU) and a newly constructed basin structure model of the target area (Yoshimi et al., 2017AGU). The comparisons between observed and simulated Green's functions generally show good agreements in the frequency range between 0.2 and 0.5 Hz. On the other hand, both observed and simulated Green's functions for some station pairs whose traverse lines run across the deeper part of the sedimentary basin (> 2000 m) show prominent later phases that might be generated and propagated inside the basin. This indicates that the understanding of the phase generation and propagation processes can be a key factor to validate the basin structure model and we investigated the characteristics of the later phases, such as its particle motions and arrival times, using observed and simulated Green's functions in detail.

    For improving the environmental quality and ensuring supply of wood and non-timber forest products, many forests have been planted in plain areas of China. Scientists have studied their benefits, almost all of the approaches were based on fixed-point data, and few was considered on the non-efficient factors and temporal scale effects. This paper studies the positive and negative benefits at a large temporal scale, and the effects of plain afforestation on stockbreeding and rural economy. The benefits of plain afforestation, correlation coefficiency of agroforestry and production factors are analyzed via stochastic frontier modeling in Huanghuaihai Plain Area of China; elastic coefficient of agroforestry, husbandry, farming, and total output of agricultural sector are calculated through adopting partial differential equation. Some conclusions can be drawn that, plain forests have an important effect on the development of plain agriculture. But shelterbelts and small-scale forests have different effect on the development of agricultural economy. Shelterbelts have negative effect on the industries, but small-scale forest has positive effect. On the whole, contribution of forest resource to value of animal husbandry and gross production value of agriculture is positive, and to the value of farming is negative.

    The Tono Geoscience Center (TGC) has been developing the GEOMASS system since 1997 to evaluate the groundwater flow at depth in a rock mass. The system provides an integrated simulation system environment for both model development and groundwater flow simulations. The integrated simulation system allows users to use resources efficiently. The system also allows users to make rapid improvement of their models as data increases. Also, it is possible to perform more realistic groundwater flow simulations due to the capability of modeling the rock mass as a continuum with discrete hydro-structural features in the rock. TGC tested the operation and usefulness of the GEOMASS system by applying to groundwater flow simulations in the Tono area, Gifu Prefecture. TGC confirmed that the system is very useful for complex geological models and multiple modeling. (author)

    The burden of HIV/AIDS in China has been disproportionately concentrated in Yunnan Province, where in Dehong prefecture, the HIV prevalence rate among pregnant women reached 1.3% in 2003, a rate that is indicative of a generalized epidemic. Since then, there have been extensive efforts to expand prevention to reduce mother-to-child transmission (MTCT) in this high-prevalence region. These intensified MTCT reduction efforts and their impact on MTCT are yet to be examined. We described the changes in access to HIV screening and antiretroviral therapy (ART) among pregnant women from 2005 to 2010 in this region and the corresponding reduction in MTCT over this period. Between 2005 and 2010, the annual number of pregnant women screened for HIV in Dehong Prefecture more than doubled. The proportion of pregnant women screened for HIV rose from an estimated 15-20% to 99.8%, and the proportion of HIV-infected pregnant women receiving ART increased from 63% to 99%. We estimate that the proportion of children born with HIV to HIV-infected mothers decreased from 15.4% to 7.2% over this period. Sustained low-level MTCT following comprehensive interventions in this region is encouraging. Over the last decade, comprehensive PMTCT efforts, coupled with national and local government policy support in this area appear to be effective.

    Full Text Available The Fukushima Daiichi Nuclear Power Plant accident caused a release of radionuclides. Radionuclides were deposited on the ground not only in Fukushima prefecture but also in nearby prefectures. Since the accident, measurement of radiation in environment such as air dose rate and deposition density of radionuclides has been performed by many organizations and universities. In particular, Japan Atomic Energy Agency (JAEA has been performing observations of air dose rate using a car-borne survey system continuously and over wide areas. In our study, using the data measured by JAEA, we estimated effective dose from external exposure in the six prefectures adjacent to Fukushima prefecture. Since car-borne survey was started a few months later after the accident, measured air dose rate in this method is mainly contributed by 137Cs and 134Cs whose half-lives are relatively long. Therefore, based on air dose rate of 137Cs and 134Cs and the ratio of deposition density of short-half-life nuclides to that of 137Cs and 134Cs, we also estimated effective dose contributed from not only 137Cs and 134Cs but also other short-half-life nuclides. We compared the effective dose estimated by the method above with that of UNSCEAR and measured data using personal dosimeters in some areas.

    The Fukushima Daiichi Nuclear Power Plant accident caused a release of radionuclides. Radionuclides were deposited on the ground not only in Fukushima prefecture but also in nearby prefectures. Since the accident, measurement of radiation in environment such as air dose rate and deposition density of radionuclides has been performed by many organizations and universities. In particular, Japan Atomic Energy Agency (JAEA) has been performing observations of air dose rate using a car-borne survey system continuously and over wide areas. In our study, using the data measured by JAEA, we estimated effective dose from external exposure in the six prefectures adjacent to Fukushima prefecture.

    An epidemiological study on canine intestinal parasites was undertaken to evaluate changes in the prevalence among private household dogs from the Hachinohe region of Aomori prefecture, Japan, in 1997, 2002 and 2007, using the formalin-ethyl acetate sedimentation technique. The risk of zoonotic transmission from household dogs to humans was also discussed. All intestinal parasites detected in the present study (Giardia intestinalis, Isospora spp., Toxocara canis, Ancylostoma caninum, Trichuris vulpis and Strongyloides stercoralis) showed no changes in prevalence over the past 10 years based on analysis considering canine epidemiological profiles. In particular, prevalence of Giardia intestinalis in dogs under 1 year old, derived from pet shops/breeding kennels and kept indoors was unchanged, remaining at a high level of >15.0% at each time point. Toxocara canis also showed no changes in the group of dogs under 1 year old, bred by private owners and kept outdoors, and the prevalence was >10.0% every year. The present results indicate that the prevalence of Giardia intestinalis and other intestinal parasites in private household dogs has not always decreased, and the potential for direct parasitic zoonotic transmission from dogs to humans may be relatively high level, than from the environment (indoors and outdoors). We recommend careful surveillance of intestinal parasites and aggressive use of anthelminthic in private household dogs under considering the epidemiological factors.

    The Hinode area of Itako City in Ibaraki Prefecture, Japan, suffered some of the most severe liquefaction damage of any areas in the Great Eastern Japan Earthquake in 2011. This liquefaction damage has been investigated by Itako City, as well as by universities and research institutes in Japan. The National Institute of Advanced Industrial Science and Technology (AIST) has carried out numerous investigations along the Tone River, and in particular, intensive surveys were done in the Hinode area. We have conducted a risk analysis based on the thickness and depth of the liquefaction layer measured using cone penetration testing (CPT) data and electric resistivity data obtained in the Hinode area. The distribution of the risk estimated from CPT at 143 points, and that obtained from analysis of the resistivity survey data, agreed with the distribution of actual damage. We also carried out conventional risk analyses method using the liquefaction resistance factor (FL) and liquefaction potential index (PL) methods with CPT data. The results show high PL values over the entire area, but their distribution did not agree well with actual damage in some parts of the study area. Because the analysis of the thickness and depth of the liquefaction layer, using geophysical prospecting methods, can cover a widespread area, this method will be very useful in investigating liquefaction risk, especially for gas and water pipelines.

    Full Text Available The Chinese government aims to deal with poverty by 2020 for people living in ethnic and rural regions, including mountainous ethnic regions with the highest concentration of poverty and chronic poverty. Based on a sustainable livelihood Framework, five capitals and 33 evaluation indices of livelihood were built, and 13 counties’ resources of the Aba Tibetan and Qiang Autonomous Prefecture were compared in order to calculate the degree of poverty. Topographic factors index of settlement sites (TFIS were constructed by eight topographic factors, and diagnoses of the dominant factors of differentiation of 2699 settlements were calculated by using the geographical detector model to establish the poverty alleviation policies and models for different regions. The results showed that the livelihood capital evaluation indices were different (0.56–1.88, and natural capitals (mean value 1.56 had obvious advantages, but physical (mean value 0.56, financial (mean value 0.78, and human capital were lower (mean value 0.93, limiting the rate of transforming the ecological resources advantage into the economy. In the TFIS, the settlement points indicate topographic factors of natural breakpoint classification superposition, including elevation, slope, relief amplitude, surface incision, variance coefficient in elevation, surface roughness, distance to roads, and distance to rivers. These are within the 8–34 range, and their power determinant value to TFIS are 0.02, 0.70, 0.77, 0.76, 0.51, 0.66, 0.06, and 0.09. Livelihood capital evaluation indices and TFIS classification one (8–14 are positively correlated, and negative correlation (22–26 and 27–34 is at the 0.05 level. The county's poverty alleviation measures and development under different livelihood indices and TFIS indicate that the ecotourism industry has become the inevitable choice for promoting rapid and coordinated development of economy, society, and the environment in ethnic regions.

    In the Northeast Honshu Arc, the Early Miocene to the Earliest Middle Miocene is a generation period of the green tuff sedimentation basin. Because the area surrounding the Asahiyama highlands is shallow in the basement and is distributed by the Middle to Lower Miocene Series, it is an optimum area to investigate the tectonics in the early green tuff period. The area near the Oguni-machi in Yamagata Prefecture, namely the area to be investigated in this study, is situated in the southern foot of the Asahiyama highlands, and the typical half-grabens can be observed there. The purpose of this study is to clarify the formation begginig period, development process and activity finishing period for the group of the half-grabens near the Oguni-machi by investigating them stratigraphically. In this area, 3 half-grabens oriented N-S and titled to the west are observed, and their generation became suddenly active in a certain period after 22 to 23 Ma and before 17.5 Ma. Then, they were filled up with the thick coarse grained sediments including the conglomerate. Their activities are considered to have declined as the regional subsidence and transgression became serious in the period of the Numazawa Formation sedimentation (about 14 Ma). 59 refs., 7 figs., 4 tabs.

    Devastating natural disasters and their aftermath are known to cause psychological distress. However, little information is available regarding suicide rates following tsunami disasters that destroy regional social services and networks. The aim of the present study was to determine whether the tsunami disaster following the Great East Japan Earthquake in March 2011 has influenced suicide rates. The study period was from March 2009 to February 2014. Tsunami disaster-stricken areas were defined as the 16 municipalities facing the Pacific Ocean in Miyagi Prefecture. Inland areas were defined as other municipalities in Miyagi that were damaged by the earthquake. Suicide rates in the tsunami disaster-stricken areas were compared to national averages, using a time-series analysis and the Poisson distribution test. In tsunami disaster-stricken areas, male suicide rates were significantly lower than the national average during the initial post-disaster period and began to increase after two years. Likewise, male suicide rates in the inland areas decreased for seven months, and then increased to exceed the national average. In contrast, female post-disaster suicide rates did not change in both areas compared to the national average. Importantly, the male suicide rates in the inland areas started to increase earlier compared to the tsunami-stricken areas, which may reflect the relative deficiency of mental healthcare services in the inland areas. Considering the present status that many survivors from the tsunami disaster still live in temporary housing and face various challenges to rebuild their lives, we should continue intensive, long-term mental healthcare services in the tsunami-stricken areas.

    This study was conducted to determine the prevalence and characteristics of Listeria monocytogenes in the feces of black beef cattle reared in geographically distant areas in Japan. We surveyed 130 farms in the following three areas: northern (Hokkaido prefecture), central (Gifu and Mie prefectures), and southern (Oita, Miyazaki, and Kagoshima prefectures) areas and collected 1738 fecal samples. Our data showed the following isolation rate for each area: northern, 11.4% of 651; central, 2.8% of 572; and southern, 2.9% of 515, indicating that the isolation rate in the northern area was significantly higher than that in the central or southern areas (pprevalent serotype (40.5%), followed by 1/2a (36.9%), 4b (21.6%), and 4ab (1.0%). In the northern area, multiple serotypes were isolated from 60% of L. monocytogenes-positive farms. In addition, multiple serotypes were isolated from individual fecal samples from 18 cattle. Pulsed-field gel electrophoresis (PFGE) characterization of 239 isolates detected 48 different PFGE types. We found that isolates from northern farms were genetically diverse compared to those from central and southern farms. Five isolates from human clinical cases and three isolates from animal clinical cases were identical to isolates from black beef cattle. Furthermore, the isolates from northern and central farms were characterized to possess epidemic clone II or III markers. We next showed that the isolates were susceptible to penicillin, ampicillin, amoxicillin, gentamicin, kanamycin, streptomycin, erythromycin, vancomycin, tetracycline, chloramphenicol, ciprofloxacin, and trimethoprim/sulfamethoxazole. Taken together, our survey provides crucial data regarding the prevalence and characteristics of L. monocytogenes in black beef cattle farms throughout Japan.

    2014-01-01

    In October 2011, the IAEA conducted an International Mission to Japan to support the remediation of large contaminated areas off-site TEPCO's Fukushima Daiichi Nuclear Power Plant (NPP). In response to the request made by the Government of Japan, in October 2013, the IAEA organized a follow-up International Mission on remediation of large contaminated areas off-site TEPCO's Fukushima Daiichi NPP (hereinafter referred to as the 'Follow-up Mission' or the 'Mission') with the main purpose of evaluating the progress of the on-going remediation works achieved since the previous mission in October 2011. The Follow-up Mission Team involved 13 international experts. Additionally, 3 experts of the Working Group 5 (Subgroup 5.2, Remediation) in charge of preparing the IAEA Report on TEPCO Fukushima Daiichi Accident accompanied the Mission as observers to obtain first-hand information for the report. The Follow-up Mission had the following three objectives: 1. To provide assistance to Japan in assessing the progress made with the remediation of the Special Decontamination Area (not included in the previous mission of 2011) and the Intensive Contamination Survey Areas; 2. To review remediation strategies, plans and works, in view of the advice provided by the previous mission on remediation of large contaminated off-site areas; and 3. To share its findings with the international community as lessons learned. The Mission was conducted through the assessment of information provided to the Team and by means of professional and open discussions with the relevant institutions in Japan, including national, prefectural and local institutions. The Japanese authorities provided comprehensive information on their remediation programme. The Mission Team visited the affected areas, including several sites where activities on remediation were conducted. The Team also visited some temporary storage sites for radioactive waste and soil generated in the remediation activities, as well as a

    Full Text Available This paper examines whether Japanese regional banks entering the banking market in other prefectures, including neighboring prefectures, can increase their lending-based income. To stimulate local economies and support local small- and medium-sized enterprises, the current Japanese Government’s policies for regional banks require these banks to engage in region-based relationship banking practices. In this study, three lending-based income measures were used as dependent variables, and estimation was made using panel data from Japanese regional banks. As a result, it was determined that regional banks that enter markets in other prefectures experience positive effects in all three lending-based income measures. Moreover, it was determined that regional banks whose headquarters are located in non-urban areas derive greater benefit from their loan businesses upon entry into other prefectures, including neighboring prefectures, where economic activity is more vibrant than regional banks whose headquarters are located in urban areas.

    The fundamental attitude of Fukushima prefecture to wrestle with nuclear power generation is explained after having described the details of inviting nuclear power plants. The prefecture intends to promote the nuclear power development in cooperation with the government, related cities, towns and villages, and electric power companies, and to develop the Futaba area, the coastal region of Pacific Ocean belonging to the low-developed area, by turning it to the base of nuclear power generation. The prefecture has improved its organization to strengthen to nuclear power administration. The prefecture also has concluded the convention on the security for nuclear power plants with Tokyo Electric Power Co. It takes care of the propagation of knowledge concerning nuclear energy and is endeavoring to provide the accurate and impartial information. The problem in promoting nuclear power generation is nothing but to obtain the consensus of inhabitants for the location of nuclear power plants. Problems on warm water discharge, employment, and of enterprises in the area inroad are to be considered on the basis of the coexistence and coprosperity of local community and power stations. The prefecture needs more powerful public relations on nuclear power, security, and fulfillment of the policy for environmental preservation, and enforcement of environmental assessment, by the government. It also demands that the enterprises complete the system that they can have their own function of the environment control. The abundant related reference are added at the end. (Wakatsuki, Y.)

    Full Text Available Ovine sera collected from the northern Prefectures of Hokkaido, Iwate and Aomori in Japan, were examined for the presence of antibodies against visna-maedi virus using the agar gel immunodiffusion test and enzyme-linked immunosorbent assays. Three animals (1.12%, out of 267 samples tested, were found to be seropositive to the visna-maedi antigens in both tests. Levels of infection were found in flocks from Hokkaido and Iwate Prefectures, but not in the Aomori Prefecture. Nucleic acid detection by polymerase chain reaction on serum samples did not give positive results. Although no diagnostic measures were in place, the infection could not be related to losses in sheep production or to reduced survival rates. The very limited visna-maedi distribution indicates a highly favourable condition for the application of eradication strategies in this area.

    Full Text Available Abstract Background Disease diffusion patterns can provide clues for understanding geographical change. Fukushima, a rural prefecture in northeast Japan, was chosen for a case study of the late nineteenth century cholera epidemic that occurred in that country. Two volumes of Cholera Ryu-ko Kiji (Cholera Epidemic Report, published by the prefectural government in 1882 and 1895, provide valuable records for analyzing and modelling diffusion. Text descriptions and numerical evidence culled from the reports were incorporated into a temporal-spatial study framework using geographic information system (GIS and geo-statistical techniques. Results Changes in diffusion patterns between 1882 and 1895 reflect improvements in the Fukushima transportation system and growth in social-economic networks. The data reveal different diffusion systems in separate regions in which residents of Fukushima and neighboring prefectures interacted. Our model also shows that an area in the prefecture's northern interior was dominated by a mix of diffusion processes (contagious and hierarchical, that the southern coastal region was affected by a contagious process, and that other infected areas experienced relocation diffusion. Conclusion In addition to enhancing our understanding of epidemics, the spatial-temporal patterns of cholera diffusion offer opportunities for studying regional change in modern Japan. By highlighting the dynamics of regional reorganization, our findings can be used to better understand the formation of an urban hierarchy in late nineteenth century Japan.

    Upon visiting Kakinoki Mine, Hyogo Prefecture, in August, 1980, the author collected the green-colored mineral in square plate form adhering on the surfaces of waste ore. It was discovered that this was torbernite, the first uranium-containing mineral discovered in the area. Its deposit classified as hydatogenetic deposit, since the Kakinoki Mine being an abandoned copper mine. Torbernite exists only in blackish pelite (waste ore), and adheres on the surface and the cleavage, either as small platy crystals or their aggregate. In the blackish pelite, numerous quartz veins were observed, where torbernite occasionally appeared. The torbernite adhering on the surface and cleavage was grass-green and translucent, and the one in the quartz veins was emerald-green and transparent or translucent. The detection of torbernite in the waste ore suggests the potentiality of finding uranium in the Kakinoki Mine. (J.P.N.)

    The QOL questionnaire version 2001 for pediatric patients with bronchial asthma and their parents or caregivers includes 15 questions for patients under the age of 4 years and 20 questions for patients over the age of 4 years. We have already reported that the QOL questionnaire version 2001 reflects reliability (including reproducibility), factorial validity, and changes in paroxysmal attacks of asthma. In this study, we revised the questionnaire for use in routine medical practice. In this study, based on the data of a previous report, the number of questions was reduced further and it was revised to the questionnaire the short form by integrated data. The revised version 2008 (Gifu) consisted of emotional burden, asthma attack, instability of symptoms and proper acceptance of asthma as a common factor, moreover 4 or more years old added load of exercise factor which consisted of two questions in each factor. This QOL short form questionnaire version 2008 (Gifu) is a disease specific questionnaire in comparison with health control, bronchial asthma and non-asthmatic patients, such as atopic dermatitis and allergic rhinitis. Although Cronbach's alpha fell with reduction of the number of questions, we conclude that it was acceptable in the clinical practice.

    1987-01-01

    As of December 1985, Kumamoto Prefecture had 14 facilities for radiotherapy, and 8 of them had capabilities of intracavitary radiotherapy. However, the computers for radiotherapy were installed in only 14 %, the simulators were installed in 36 %, and radiotherapy by radiologist was carried out in 64 % of these facilities. In Kumamoto, 1120 patients were treated by external radiotherapy and 83 patients by intracavitary radiotherapy per year. Two-hundred and thirty-one cases of them were lung cancer, 142 uterine cervical carcinoma, 92 esophageal cancer, and 79 breast cancer. The radiotherapeutic rate of patients which were estimated as neoplasms was only 23 % for all sites, but it was 77 % for the larynx, 65 % for the esophagus, 61 % for the uterus, and 42 % for the lung. The results of this study suggest that radiotherapists must make an effort to carry out more precise radiotherapy and also to extend the indication of radiotherapy. (author)

    Sarcoptes scabiei is the causal agent of sarcoptic mange in domestic/companion dogs (Canis lupus familiaris) and raccoon dogs (Nyctereutes procyonoides). Although there have been successful cases of experimental transmission of S. scabiei from mangy wild Canidae hosts to healthy dogs, and suspected cases of transmission between raccoon dogs and companion dogs, no clear-cut evidence has been obtained. In the present study, the genetic relationships between Sarcoptes mites from raccoon dogs and companion dogs living in the same region were elucidated.One hundred and thirty Sarcoptes mites from 22 raccoon dogs and 5 companion dogs were collected from the Gifu area in Japan. Using 9 microsatellite markers, the genotypes were compared, and the genetic structure of these mites was analyzed. In 6 pairs of companion dog- and raccoon dog-derived mites, 17 out of the 18 alleles analyzed were identical. Using a Bayesian approach, these 130 mites were separated into at least two groups, and companion dog- and raccoon dog-derived mites were segregated into both groups. In addition, comparatively large numbers of alleles at these loci were revealed by comparison with data from past studies. These results demonstrated that the host specificity at the 9 microsatellite-level could not be confirmed, strongly suggesting the transmission of Sarcoptes mites between raccoon dogs and companion dogs. This is the first report to provide a genetic evidence of Sarcoptes transmission between domestic and wild mammals in the natural environment. The possibility of a prior introduction of mites with novel genotypes (e.g., spillover of sarcoptic mange from domestic/companion dogs to raccoon dogs) could not be eliminated when considering the cause of the large number of alleles, and the coexistence of 2 mite groups in sympatric raccoon dogs and companion dogs in this local area.

    The accident of the Fukushima Dai-ichi nuclear power plant of Tokyo Electric Power Cooperation (TEPCO) after the great east Japan earthquake (11 March 2011) elevated the background level of environmental radiation in Eastern Japan. Around the Tokyo metropolitan area, especially around Kashiwa and Nagareyama cities, the ambient dose equivalent rate has been significantly increased after the accident. Responding to strong requests from citizens, the local governments started to monitor the ambient dose equivalent rate precisely and officially, about 3 months after the accident had occurred. The two cities in cooperation with each other also organised a local forum supported by three radiation specialists. In this article, the activities of the local governments are introduced, with main focus on radiation monitoring and measurements. Topics are standardisation of environmental radiation measurements for ambient dose rate, dose mapping activity, investigation of foodstuff and drinking water, lending survey meters to citizens, etc. Based on the data and facts mainly gained by radiation monitoring, risk management and relating activity have been organised. 'Small consultation meetings in kindergartens', 'health consultation service for citizens', 'education meeting on radiation protection for teachers, medical staffs, local government staffs, and leaders of active volunteer parties' and 'decontamination activity', etc. are present key activities of the risk management and restoration around the Tokyo metropolitan area.

In the Ohdate-Kazuno area, moderate temperature hot springs of meteoric water origin are found, which may exist as rather shallow formation water in the Green Tuff formations. On the contrary, high temperature geothermal waters of meteoric origin, which are used for power generation, are obtained in two volcanic area of Hachimantai and Oyasu. Those geothermal waters are expected to come up through vertical fissures from depth deeper than 2 km. The difference of these two manners of meteoric water circulation should be necessarily explained to understand the relationship of shallow and deep geothermal systems. About some hot springs of fossil sea water origin, the relationships of δ D and Cl - don't agree to the mixing relation of sea water and meteoric water. This may be explained by two different processes, one of which is mixing of sea water with saline meteoric water (Cl - ca. 12 g/kg). The other is modification of δD by hydrogen isotopic exchange with hydrous minerals underground, or by exchange with atmospheric vapor during a relic lake before burying. (author)

    We have collected natural and sociological environmental data related to the estimation of radiation dose by radionuclides which will be released from nuclear fuel cycle facilities. Published data concerning production and distribution of livestock products in Aomori Prefecture were collected and compiled. We tried to estimate market dilution coefficient, which is the ratio of local products to total consumption by people in a target area, for the livestock products from the compiled data under some assumptions. Production weight per unit field area (production density) and consumption rates of grass and feed by the domestic animals were also estimated by using the collected data. Estimated means of the market dilution coefficients for livestock products and production density of grass were lower than those used in the environmental assessment for a reprocessing plant now under construction in Rokkasho Village. Consumption rates of grass and feed by milk cows and beef cattle were higher than those used in the assessment. Since we assumed that milk cows and beef cattle of Aomori Prefecture consume only grass and feed produced in Aomori Prefecture, the rates may be overestimated. Further study is required to clarify this point. We collected 52 reports in the literature related to transfer reduction of radionuclides to livestock products and decontamination of the radionuclides. (author)

    The earthquake occurred in 1996 near the border of Akita and Miyagi Prefectures was a seismic activity in mountainous area with low population density. However, since a necessity was felt to make a seismic intensity survey, a questionnaire investigation was carried out. The investigation placed a focus on the following points: (1) to learn seismic intensity distribution in the vicinity of the epicenter by using replies to the questionnaire and (2) to learn what evacuation activities the residents have taken to avoid disasters from the earthquake, which is an inland local earthquake occurred first since the Hyogoken-nanbu earthquake in 1995. Because the main shock has occurred in the Akita prefecture side, the shocks were concentrated at Akinomiya, Takamatsu, Sugawa and Koyasu areas where the intensities were 4.0 to 4.5 in most cases. The largest aftershocks were concentrated to the Miyagi prefecture side, with an intensity of 6.0 felt most, followed by 5.5. The questionnaire on evacuation actions revealed a result of about 37% of the reply saying, ``I have jumped out of my house before I knew what has happened`` and ``I remember nothing about what I did because I was acting totally instinctively``. The answers show how intense the experience was. This result indicates how to make the unconscious actions turned into conscious actions is an important issue in preventing disasters. 11 figs.

    Geographical inequalities in suicide have risen dramatically across 47 prefectures in Japan since 1995. We sought to examine temporal changes in the associations between prefecture-level economic conditions and completed suicide during the recent 35 years, controlling for individual composition in each prefecture. Based on quinquennial vital statistics and census data from 1975 to 2010, we analysed the entire population aged 25-64 years. The total number of suicides was 87 553 men and 34 559 women. As indicators of prefecture-level economic conditions, we used average yearly income, average savings and income inequality (measured by Gini coefficients for yearly income). For each sex, we estimated odds ratios and 95% credible intervals for suicide using multilevel logistic regression models, with cells at level 1, years at level 2 and prefectures at level 3. Even after adjusting for individual age, occupation and time trends, low average savings at prefecture level were associated with a higher risk of suicide among men (odds ratio in low vs. high savings: 1.13, 95% credible interval: 1.05-1.21), whereas no clear patterns were observed with other economic indicators. When we further examined the associations in year-specific models by conducting a two-level analysis, both average yearly income and average savings were inversely associated with suicide risk in recent years. No clear association was found between income inequality and suicide risk for either sex. The present findings suggest that low area socioeconomic status may be driving the growing geographical inequalities in suicide in Japan, primarily among men. © The Author 2014.

    Successful case studies for waste recycling in Japan have not been evaluated. The evaluation of economic efficiency and environmental effects were lacking at the time the actual network was established. A waste/resource input/output (I/O) coincidence retrieval system called ZENESYS was developed to examine the usefulness of a waste-exchange network in a nonmanufacturing district. We analyzed data from the Miyagi prefecture, a region without heavy industry. The data were collected from 77 companies using a questionnaire and interviews. A total of 33 possible waste exchange links arose after analysis using ZENESYS. However, these were frail networks that relied heavily on the construction industry. Two waste recycling technologies were selected from the ZENESYS database: reclaiming fuel from waste plastic and making construction materials from bottom ash. Evaluation of the environmental effects and economics of these two technologies showed they were both suitable for the environment, but no profit was made from reclaiming fuel from waste plastics. We concluded that in an area with no heavy industry, it may be difficult to adopt recycling technologies that have high environmental and economic performance. Materials are difficult to circulate among manufacturing industries even if a waste-exchange network exists, and resources are consumed during transportation and recycling.

    This study aimed to clarify the correlation between the 2011 Great East Japan Earthquake and domestic violence (DV) against pregnant females after the disaster in Miyagi Prefecture, an area damaged by the earthquake and tsunami. We analyzed 7600 pregnant females from June to December 2011. The incidence of physical and mental DV and the proportions in the inland, north coastal, and south coastal areas of Miyagi Prefecture and nationwide were calculated, and a chi-square test was conducted for comparison. The risk factors for DV were estimated with multivariate logistic regression analyses on a prefecture-wide basis. The incidence levels for physical DV were found to be 5.9% in the north coastal area, which was significantly higher than in the inland area (1.3%, P=0.0007) and nationwide (1.5%, P<0.0001). There were no significant differences in the incidence of mental DV between the 3 areas in Miyagi Prefecture (inland 15.2%, north coast 15.7%, and south coast 18.8%) or nationwide (13.8%). Experiencing disease or injury in someone close and changes in the family structure were significantly associated with mental DV in Miyagi Prefecture. Continuous monitoring and support for pregnant females may be necessary to address this issue in disaster-affected areas. (Disaster Med Public Health Preparedness. 2017;11:216-226).

    Despite the enormous cost of radiation decontamination in Fukushima Prefecture, it is not clear what levels of reduction in external radiation exposure are possible in the Special Decontamination Area, the Intensive Contamination Survey Areas and the whole of Fukushima. The objective of this study was to evaluate the cost and effectiveness of radiation decontamination in Fukushima Prefecture in its entirety. Using a geographic information system, we calculated the costs of removal, storage containers, transport, and temporary and interim storage facilities as well as the reduction in air dose rate for a cumulative external exposure for 9000 1 km × 1 km mesh units incorporating 51 municipalities. The decontamination cost for the basic scenario, for which forested areas within 20 m of habitation areas were decontaminated, was JPY2.53–5.12 trillion; the resulting reduction in annual external dose was about 2500 person-Sv. The transport, storage, and administrative costs of decontamination waste and removed soil reached JPY1.55–2.12 trillion under this scenario. Although implementing decontamination of all forested areas provides some major reductions in the external radiation dose for the average inhabitant, decontamination costs could potentially exceed JPY16 trillion. These results indicate that technologies for reducing the volume of decontamination waste and removed soil should be considered to reduce storage costs and that further discussions about forest decontamination policies are needed. - Highlights: • Evaluation of cost and effectiveness of decontaminating Fukushima Prefecture. • Reductions in external exposure under various decontamination scenarios were similar. • Decontamination costs for the basic scenario were estimated at JPY2.53–5.12 trillion.

    Inoculation assays with Pantoea eucalypti M91 were performed on Lotus japonicus ecotype Gifu. Under alkaline conditions, this ecotype is characterized by the development of interveinal chlorosis of the apical leaves due to low mobilization of Fe(2+). Inoculation with P. eucalypti M91, a plant growth-promoting bacterial strain capable of producing pyoverdine-like and pyochelin-like siderophores under alkaline growth conditions, alters the root, resulting in a herringbone pattern of root branching. Additional features include improvement in Fe(2+) transport to the shoots, acidification of the hydroponic solution of the plant cultures, and an accompanying increase in the efficiency of the PSII parameters. In addition, there was an increase in the expression of the FRO1 and IRT1 genes, accompanied by a significant increase in FRO activity. Results showed that P. eucalypti M91 has a beneficial effect on the Fe acquisition machinery of Strategy I, as described for non-graminaceous monocots and dicots, suggesting its potential as an inoculant for legume crops cultivated in alkaline soils.

    Full Text Available Background: The prevalence of frontotemporal lobar degeneration (FTLD in Japan is unknown. An epidemiological survey study of FTLD was undertaken in Tottori Prefecture, a district in the western region of Japan. Methods: Hospitals in Tottori Prefecture were surveyed by a two-step questionnaire in 2010, and the prevalence of FTLD per 100,000 inhabitants was calculated using the actual number of patients and inhabitants in Tottori Prefecture on the prevalence day of October 1, 2010. Results: In this survey, 66 patients were diagnosed with FTLD. The subtypes of FTLD were as follows: 62 cases of frontotemporal dementia (FTD, 3 cases of progressive nonfluent aphasia, and 1 case of semantic dementia. Among the FTD cases, 5 cases were FTD with motor neuron disease and 1 case was FTD with parkinsonism linked to chromosome 17. The prevalence of FTD in the total population of Tottori Prefecture was 11.2 per 100,000 inhabitants. Based on these results, the prevalence of FTLD in Japan in 2008 was estimated to be 9.5 per 100,000 individuals. Conclusions: Our epidemiological survey results suggest that there are at least 12,000 FTLD patients in Japan, indicating that FTLD is not a rare disease.

    Objective Due to the Great East Japan Earthquake, which occurred in March 2011, many residents of Fukushima Prefecture were affected by a radiation accident in addition to suffering loss or damage from the earthquake and the subsequent tsunami. The aim of this study was to evaluate the actual condition of patients with peptic ulcers related to the disaster. Methods Patients with peptic ulcers at six hospitals in three different regions of Fukushima Prefecture during the two months following the disaster and the corresponding period of the year before and the year after the disaster were enrolled in this study. Changes by period and region in the number of esophagogastroduodenoscopy (EGD) examinations and the number of peptic ulcer patients were evaluated as the primary endpoints. Changes in the frequencies of hemorrhagic ulcers were evaluated by period and by region as secondary endpoints. Results The numbers of EGDs and peptic ulcer cases compared to the previous year decreased in 2011 and then increased in 2012. However, the ratio of hemorrhagic ulcers to peptic ulcers was higher in 2011 (51.9%) than in 2010 (38.1%) and 2012 (31.1%), and the 2011 hemorrhagic ulcer ratio was the highest at 63.6% in the coastal area. Regarding bleeding cases during 2011, the rate at 1 month after the disaster (64.1%) was higher than the rate at 2 months after the disaster (40.5%) (p=0.033). Conclusion The number of patients with peptic ulcers did not increase immediately following the disaster in Fukushima Prefecture. However, the rate of bleeding patients increased soon after the disaster, especially in the coastal area.

    It has been reported that morbidity from allergic rhinitis in the National Health Insurance records in Ibaraki Prefecture for May correlated with the quantity of Japan cedar pollen scattered in each year. The purpose of the present investigation was to clarify the Japanese cedar pollinosis contribution to morbidity, and also clarifying the influence of air pollution and medical resources on the crisis and symptoms of allergic rhinitis. The charts in four otolaryngology facilities were used for analyzing the Japan cedar pollinosis content with reference to the allergic rhinitis during the pollen season. The age-adjusted morbidity of allergic rhinitis was annually compared employing data of National Health Insurance records for medical examinations made in May during the period between 1988 and 1996 in Ibaraki Prefecture. The quantity of Japanese cedar pollen was measured at seven area points in Ibaraki Prefecture during the three-year period from 1994 to 1996, and was compared with the degree of Japan cedar wood occupation in each municipality. Traffic volume according to municipalities in Ibaraki Prefecture was taken as a surrogate indicator of air pollution. The area otolaryngology facilities and doctors were taken as medical resources. Values were thus compared with allergic rhinitis morbidity. Sixty to eighty percent of the allergic rhinitis patients examined in May were found to be suffering from pollinosis. The quantities of Japanese cedar pollen scatter at the seven points in Ibaraki Prefecture varied in concert every year, the quantities correlating well with the area of Japanese cedar woods stands in each municipality in some but not in other years. The morbidity in the records of allergic rhinitis according to municipalities correlated negatively with the proportion of the population occupied in farming (r = -0.38) and with the area of Japanese cedar woods in each municipality (r = -0.40). The traffic volume calculated according to municipalities in

    During 2011-2014, we measured (3)H concentrations in river water samples collected during base flow conditions and during several flood events from two small rivers in a mountainous area in Fukushima Prefecture, which received deposition of (137)Cs from the Fukushima Dai-ichi Nuclear Power Plant accident. (3)H concentrations above background levels were found in water samples collected during both base flow conditions and flood events in 2011. The (3)H concentrations during flood events were generally higher than those during base flow conditions. The (3)H concentrations in both rivers during base flow conditions and flood events decreased with time after the accident and reached almost background levels in 2013. We also measured (3)H concentrations in freshwater samples from 16 other rivers and one dam in eastern Fukushima Prefecture from 2012 to 2014 during base flow conditions. The measured (3)H concentrations were higher than the background level in 2012 and decreased with time. The (137)Cs inventory in the catchment area at each sampling point was estimated from air-borne monitoring results in the literature and compared with the (3)H concentrations. We found surprisingly good correlations between (137)Cs inventories in the catchment areas and (3)H concentrations in the water samples. Further studies will be necessary to clarify the reason for the good correlation. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The activities of seven kinds of apples produced in Aomori prefecture were measured with a high pure Ge detector set in a 15 cm-thick lead shield. The activities of 40 K were detected in all samples, but an artificial radioactive nuclide was not detected. The slices of an apple were contacted to an imaging plate for 15 days in a 15 cm-thick lead shield and cross sectional activity distributions were measured. By using the distribution map, the activities of skin, flesh and lead portion of an apple 'Ohrin' were calculated to 0.041, 0.032 and 0.046 Bq/g, respectively. This measuring system will be used for the activity estimations of the farm products, specially apples, because of that many atomic institutions are in operation and in the planning stage on Aomori prefecture.

    Fukushima Prefecture chose about 360,000 people who were 18 years old or younger at the time of the accident at Fukushima Daiichi NPS on March 11, 2011, and started thyroid test as part of the prefectural health survey on October 9, 2011. The survey is entrusted to Fukushima Medical University of Medicine from Fukushima Prefecture. This fact sheet summarizes the current state of thyroid test in Fukushima Prefecture. A considerable amount of data and related information have been accumulated in the seventh year from the beginning. However, especially the information disclosed in English by people concerned combined the results of the second round, which was not analyzed properly, with those of the first round. This fact gives a suspicion of intention to deny the possibility of radiation influence in such a way as to make it invisible even if there was the influence. This study firstly prepared an English fact sheet to convey the actual situation in English. However, since some official information/views were contained in papers only available in English, this study also prepared the Japanese version for enabling to grasp the current situation. The Japanese version is supplemented with explanation rather than the Japanese translation of the English version, in order to make it easier to understand. The future of thyroid test is a topic that is causing controversy. Now that the transparency, scientific fairness, and the data integrity of Fukushima Medical University are suspected, it is extremely important that an independent analysis in the true sense is to be performed by qualified experts based on the latest evidence.

    Thyroid cancer is one of the major health concerns after the accident in the Fukushima Dai-ichi nuclear power station (NPS). Currently, ultrasonography surveys are being performed for persons residing in the Fukushima Prefecture at the time of the accident with an age of up to 18 years. Here, the expected thyroid cancer prevalence in the Fukushima Prefecture is assessed based on an ultrasonography survey of Ukrainians, who were exposed at an age of up to 18 years to 131 I released during the Chernobyl NPS accident, and on differences in equipment and study protocol in the two surveys. Radiation risk of thyroid cancer incidence among survivors of the atomic bombings of Hiroshima and Nagasaki and preliminary estimates of thyroid dose due to the Fukushima accident were used for the prediction of baseline and radiation-related thyroid cancer risks. We estimate a prevalence of thyroid cancer of 0.027 % (95 % CI 0.010 %; 0.050 %) for the first screening campaign in the Fukushima Prefecture. Compared with the incidence rate in Japan in 2007, the ultrasonography survey is predicted to increase baseline thyroid cancer incidence by a factor of 7.4 (95 % CI 0.95; 17.3). Under the condition of continued screening, thyroid cancer during the first fifty years after the accident is predicted to be detected for about 2 % of the screened population. The prediction of radiation-related thyroid cancer in the most exposed fraction (a few ten thousand persons) of the screened population of the Fukushima Prefecture has a large uncertainty with the best estimates of the average risk of 0.1-0.3 %, depending on average dose.

    The Japan Environment and Children's Study is an ongoing nationwide birth cohort study that is being conducted at 15 regional centers throughout Japan. The recruitment of subjects in the study area within Fukushima Prefecture, which includes Fukushima City, Minami Soma City and Futaba County, was begun on January 31, 2011 with the cooperation of the obstetrics and gynecology departments of local medical institutions. On March 11, soon after the start of recruitment, the Tohoku region was hit by an unprecedented disaster in the shape of the Great East Japan Earthquake, which was closely followed by the Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Plant accident. As a result of the disaster, the study area in Fukushima Prefecture was expanded on October 1, 2012 to include 59 municipalities across Fukushima Prefecture. Three points are seen as particularly important: 1) Radiation risk communication, 2) The motto is "Be attentive. Be supportive.", and 3) Establishing cooperating partnerships. With the cooperation of all concerned, the recruitment period ended on March 31, 2014. The tentative total number of the participants enrolled at the Fukushima Regional Center was 34,666 (13,134 pregnant mothers, 8,695 fathers and 12,837 children born before November 30, 2014 as of June 2016).

    On 11 March 2011, the Great East Japan Earthquake followed by a powerful tsunami hit the Pacific Coast of Northeast Japan and damaged Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Plant, causing a radiation hazard in Fukushima Prefecture. The objective of this report is to describe some results of a questionnaire-based pregnancy and birth survey conducted by the Radiation Medical Science Center for the Fukushima Health Management Survey. Questionnaires were sent to women who received maternal and child health handbooks from municipal officers in Fukushima Prefecture between 1 August 2010 and 31 July 2011, with the aim of reaching those who were pregnant at the time of the disaster. Mailing began 18 January 2012. Data were analyzed separately for six geographic areas in Fukushima Prefecture. The total number of women meeting survey criteria was 15,972. The number of responses received to date is 9,298 (58.2%). Data from 8602 respondents were analyzed after excluding 634 invalid responses and 5 induced and 57 spontaneous abortions (less than 22 gestational weeks). The incidences of stillbirth (over 22 completed gestational weeks), preterm birth, low birth weight and congenital anomalies were 0.25%, 4.4%, 8.7% and 2.72%, respectively. These incidences are similar to recent averages elsewhere in Japan. Considering the pregnancy and birth survey data in aggregate, our disaster seemed to provoke no significant adverse outcomes over the whole of Fukushima prefecture. But post-disaster prenatal care and support intended for patients' safety and security should be coupled with ongoing surveillance and rigorous data analysis.

    To detect cervical carotid stenosis as a candidate for carotid endarterectomy (CEA), the authors attempted a prospective trial by exploring stenosis for one year in a rural district with a population of 20,000, employing helical CT angiography which apparently displayed three-dimensional reconstructed images of the carotid bifurcation. Thirty-three patients, 24 males and 9 females, with a mean age of 71.8 years, suffering from TIA, RIND or stroke were investigated for their carotid systems. The clinical symptoms of the patients were briefly as follows: motor weakness in 30 cases, dysarthria in 8 cases and aphasia in 4 cases; and 6 of 22 (27%) stroke cases had previously suffered an episode of TIA. The risk factors of the whole group of patients were hypertension in 13 cases, diabetes mellitus in 6, heart disease in 17, and hypercholesteremia in 4. Helical CT angiography was performed in 11 cases of TIA, 2 cases of RIND, and 16 cases of stroke. Only 3 cases of the TIA group and 3 cases of the stroke group were found to have extracranial carotid stenosis of more than 50%, which subsequently required conventional angiography. For the detection of stenosis, CT angiography was beneficial as well as conventional angiography. Finally, CEA was performed in 2 of 3 cases with severe carotid stonosis in the TIA group, while such cases in the stroke group were only observed. The above results meant that the occurrence of extracranial carotid stenosis was 6 out of 6,589 elderly inhabitants (over 60 years old), although the possible detection rate of candidates for CEA was 2 out of 20,000 population per year.

    To detect cervical carotid stenosis as a candidate for carotid endarterectomy (CEA), the authors attempted a prospective trial by exploring stenosis for one year in a rural district with a population of 20,000, employing helical CT angiography which apparently displayed three-dimensional reconstructed images of the carotid bifurcation. Thirty-three patients, 24 males and 9 females, with a mean age of 71.8 years, suffering from TIA, RIND or stroke were investigated for their carotid systems. The clinical symptoms of the patients were briefly as follows: motor weakness in 30 cases, dysarthria in 8 cases and aphasia in 4 cases; and 6 of 22 (27%) stroke cases had previously suffered an episode of TIA. The risk factors of the whole group of patients were hypertension in 13 cases, diabetes mellitus in 6, heart disease in 17, and hypercholesteremia in 4. Helical CT angiography was performed in 11 cases of TIA, 2 cases of RIND, and 16 cases of stroke. Only 3 cases of the TIA group and 3 cases of the stroke group were found to have extracranial carotid stenosis of more than 50%, which subsequently required conventional angiography. For the detection of stenosis, CT angiography was beneficial as well as conventional angiography. Finally, CEA was performed in 2 of 3 cases with severe carotid stonosis in the TIA group, while such cases in the stroke group were only observed. The above results meant that the occurrence of extracranial carotid stenosis was 6 out of 6,589 elderly inhabitants (over 60 years old), although the possible detection rate of candidates for CEA was 2 out of 20,000 population per year.

    An accident of Fukushima Daiichi nuclear power plant induced by an earthquake of M9.0 and subsequent tsunami gave various kinds of impacts around the plant. After reviewing arguments of local governments for low dose radiation risk, this paper analyzed social impacts by the risk in terms of a gap of emergency response between national and local governments, corruption of communities in various levels induced by plural statements for risk levels in low level radiation, and economic impacts for agricultural crops made in Fukushima prefecture. Afterwards, clues for improving the situation were discussed, which include understanding of characteristics of public perception, attitudes of experts and interactive risk communication. (author)

    The data on 158 cases of lung cancer treated with radiotherapy at three hospitals (Hospital of School of Med., Gunma Univ., National Takasaki Hospital and Gunma Cancer Center Hospital) were analized. 1. Seventy one cases (44.9%) of all patients were more than 70 years old. As the histological type, epidermoid carcinoma was recognized in 44% of male patients, and adenocarcinoma in 51.5% of female. The number of patients with epidermoid carcinoma tended to increase with age. 2. Gunma Cancer Center was different from other hospitals in that half of the female patients (6/12) were stage I, adenocarcinoma. 3. The dwelling area of patients in Gunma Cancer Center Hospital distributed over towns and counties at the east district in Gunma prefecture, whereas in other hospitals concentrated in Maebashi and Takasaki cities.

    The tsunami sediments and their directly under soils from 25 tsunami flooded areas in Miyagi prefecture after the Great East Japan Earthquake were analyzed quantitatively for radiocesium ( 134 Cs and 137 Cs) concentrations. It was found that the radiocesium released in the reactor accidents of the Fukushima Daiichi Nuclear Power Plant stayed for at least 6 months in the tsunami sediments layer of a few centimeter thickness. On the other hand, from the results of the radiocesium extraction test using the tsunami sediments and 3 kinds of inorganic solvents, it was also found that the radiocesium in the tsunami sediments passed ca. 6 months after fall was hardly eluted with rain water (pH 5.6 ∼ 7.0) and combined strongly with clay minerals in the tsunami sediments.

    1977-07-01

    Geographic pattern of lung cancer mortality in Fukuoka Prefecture showed elevated mortalities among males in the Chikuho district where many coal-mines had long been operated as one of the biggest coal-mining areas in Japan. The analysis in relations of occupations to lung cancer mortality revealed that consistently significant correlations exist between lung cancer mortality, and mining and quarrying occupations in every census year after World War II. No other occupations showed consistent relations to lung cancer though a few significant correlations were found only in the recent years. The results appear to suggest that elevated risk of lung cancer among coal-mining workers may exist and deserve further analytical study.

    To obtain an average dose from 222 Rn to the people in Aomori Prefecture where the first Japan's nuclear fuel cycling facilities are now under construction, we surveyed 222 Rn concentrations in 109 dwellings in the Prefecture from 1992 to 1996. The outdoor 222 Rn concentrations were also measured in gardens of 15 dwellings. The 222 Rn concentrations were measured with passive 222 Rn detectors which used a polycarbonate film for counting α-ray and could separate concentrations of 222 Rn from 220 Rn. Counting efficiencies of the detectors were calibrated with a standard 222 Rn chamber in the Environmental Measurement Laboratory in USA and in the National Radiological Protection Board in UK. Geometric means of 222 Rn concentration were 13 and 4.4 Bq x m -3 in the dwellings and outdoor, respectively. These values were consistent to nationwide survey results in Japan. The 222 Rn concentrations in the dwellings depended on their age. The concentrations were higher in recent dwellings than in older ones. The radiation dose from 222 Rn was estimated, taking into account the occupancy factor for inside and outside of dwellings. The annual dose was 0.32 mSv x y -1 , and 99% of the dose came from the exposure to 222 Rn inside the dwelling. (author)

    A catastrophic undersea megathrust earthquake of magnitude 9.0 off the coast of Japan occurred at 14:46 JST on Friday, 11 March 2011. The earthquake triggered powerful tsunami waves, and the tsunami precipitated Fukushima nuclear accidents. After the terrible earthquake, many people fled from the nuclear accident and arrived at places far from the nuclear power plant. In this article, I present a story of one measure devised to deal with the problem of the Fukushima nuclear accident at a regional hospital of Fukushima prefecture, Aizu General Hospital, which is located far from the Fukushima nuclear plant. In addition, I briefly report the current situation of Fukushima prefecture after the 2011 Great East Japan earthquake. In our hospital, the countermeasure headquarters was established to supply medical care for those who had been injured by tsunami waves and the Fukushima nuclear accident. Especially, the screening for radioactive exposure using a dosimeter to take decontamination measures for cases of external exposure was extremely important task. Nevertheless, because the accurate knowledge related to radioactive contamination didn't provide, most medical staff fell into confusion. Fukushima prefecture has been 'shrinking' since the nuclear accident. However, today, although some hot spots remain in residential areas, the radioactive contamination is decreasing little by little. Many people in Fukushima Prefecture advance as one, facing forward. Recently, decontamination projects started. Efforts must be continued over a long period. © 2012 The Author. Digestive Endoscopy © 2012 Japan Gastroenterological Endoscopy Society.

    Full Text Available Background: In the aftermath of the Great East Japan Earthquake, most of the areas in Yamagata prefecture experienced a serious power failure lasting for approximately 24 hours. A number of households were subsequently poisoned with carbon monoxide (CO due to various causes. In this study, we conducted a survey of CO poisoning during the disaster. Methods: A questionnaire regarding CO poisoning associated with the disaster was sent to 37 emergency hospitals in Yamagata prefecture. Results: A total of 51 patients were treated for unintentional CO poisoning in 7 hospitals (hyperbaric oxygen chambers were present in 3 of the hospitals. The patients (18 men, 33 women ranged in age from 0 to 90 years. The source of CO exposure was charcoal briquettes (23 cases; 45%, gasoline-powered electric generators (18 cases; 35%, electric generators together with oil stoves (8 cases; 16%, oil stoves (1 cases; 2%, and automobile exhaust (1 cases; 2%. Blood carboxyhemoglobin levels ranged from 0.5% to 41.6% in 49 cases. Of these, 41 patients were treated by normobaric oxygen therapy, while one was intubated for artificial respiration. Additionally, 5 patients (10% were treated by hyperbaric oxygen therapy, and 3 patients (6% experienced delayed neuropsychiatric sequelae. Conclusion: CO sources included gasoline-powered electric generators and charcoal briquettes during the disaster. Storm-related CO poisoning is well recognized as a disaster-associated accident in the United States, but not in Japan. We emphasize that public education is needed to make people aware of the dangers of CO poisoning after a disaster. In addition, a pulse CO-oximeter should be set up in hospitals.

    About 15 PBq from both {sup 134}Cs and {sup 137}Cs were released from the Fukushima Dai-ichi Nuclear Power Plant (NPP) because of venting operations and hydrogen explosions. The Ministry of Education, Culture, Sports, Science and Technology of Japan reported total surface deposition of {sup 134}Cs and {sup 137}Cs in Japan. To estimate short-term and long-term impacts of the radiation dose in Japan, it is important to understand the dynamics of radionuclides, especially those of {sup 134}Cs and {sup 137}Cs, on river watershed environments. This study investigated {sup 134}Cs and {sup 137}Cs radioactivity in river systems in Fukushima, Miyagi, Ibaraki and Gunma prefectures, Japan. The secondary radioactive dispersion of radiocesium from the contaminated watershed to the river waters is reported for research areas with widely various radiocesium deposition on ground surfaces at 18 months after the accident. Field experiments were conducted at a fixed station in four rivers (the Uta, Niida, Natsui, and Same Rivers) in Fukushima Prefecture, and the Kuji River, and Naka River in Ibaraki Prefecture in August 2012. The Abukuma River was set up one site at the upper, two sites in the middle reach in Fukushima Prefecture and at one site in the lower area in Miyagi Prefecture. The Tone River system has three stations at the upper river area in Gunma Prefecture and one site at the lower reach in Ibaraki Prefecture. Surface deposition results reveals significant external radioactivity in a zone extending northwest from the NPP. However, a mountainous area in Gunma Prefecture, located about 220 km from Fukushima Dai-ichi NPP south of Fukushima Prefecture, shows similar accumulation of {sup 134}Cs and {sup 137}Cs. The 20 L of surface river waters were collected at the station using buckets. The radioactivity of {sup 134}Cs and {sup 137}Cs in the river waters was measured with gamma-ray spectrometry using ammonium molybdophosphate (AMP)/Cs compound method with a low background Ge

    Monitoring and surveying radioactivity in seawater and biota in the marine environment off the coast of Fukushima prefecture in the Pacific are important for understanding the dispersion of artificial radionuclides after TEPCO's Fukushima Daiichi Nuclear Power Plant (F1NPP) accident. Marine biota were collected in the coastal area of Fukushima prefecture after this accident due to investigate the activities of 134 Cs, 137 Cs, and 110m Ag in marine biota, including not only fish and shellfish but also benthos. It is well known that 108m Ag, one of the radioactive isotopes of Ag, was observed in some kinds of squid and octopus before this accident. As the results, 110m Ag was observed in many kinds of marine biota off the coastal area of Fukushima. It is suggested that rapid change in the radioactivities in seawater, resuspension of particles from sediments and food chain effects led to high radionuclide activities in marine biota after this accident.

    Full Text Available Background: We reutilized the existing Three-Prefecture Cohort to evaluate the relationship between lifestyle factors and the incidence or mortality from non-communicable diseases. Methods: This study was a prospective population-based observation conducted from the 1980s to 2000 in three prefectures (Miyagi, Aichi, and Osaka in Japan. The study subjects were residents aged ≥40 years who received a questionnaire. The follow-up period was 15 years from the baseline survey in each study area. A self-administered questionnaire, which included items on participants' demographic factors and lifestyle characteristics, was administered. Vital status and date of death were collected from residence certificates by the local government, and cause of death was identified using vital statistics. Cancer incidence and the date of diagnosis were collected from local cancer registry data. Results: A total of 46,421 men and 54,189 women were eligible for our analysis. The person-years of follow-up for cancer incidence were 464,664 and 567,271 for men and women, respectively, and those for death were 527,940 and 648,601 for men and women, respectively. There were 8479 cancer incidences (5106 men and 3373 women and 20,240 total deaths (11,156 men and 9084 women. The stomach was the most common cancer incidence site for both men (25.6% and women (18.6%. The leading cause of death was cancer among men (35.0% and cardiovascular disease among women (41.0%. Conclusions: The Three-Prefecture Cohort Study enabled us to reveal the association of multiphasic lifestyle factors with cancer incidence and mortality. The study will also allow us to conduct a pooled analysis in combination with other large-scale cohorts.

    Research on landslide susceptibility has evolved rapidly over the few last decades thanks to the availability of large databases. Landslide research used to be focused on discreet events but the usage of large inventory dataset has become a central pillar of landslide susceptibility, hazard, and risk assessment. Indeed, extracting meaningful information from the large database is now at the forth of geoscientific research, following the big-data research trend. Indeed, the more comprehensive information of the past landslide available in a particular area is, the better the produced map will be, in order to support the effective decision making, planning, and engineering practice. The landslide inventory data which is freely accessible online gives an opportunity for many researchers and decision makers to prevent casualties and economic loss caused by future landslides. This data is advantageous especially for areas with poor landslide historical data. Since the construction criteria of landslide inventory map and its quality evaluation remain poorly defined, the assessment of open source landslide inventory map reliability is required. The present contribution aims to assess the reliability of open-source landslide inventory data based on the particular topographical setting of the observed area in Niigata prefecture, Japan. Geographic Information System (GIS) platform and statistical approach are applied to analyze the data. Frequency ratio method is utilized to model and assess the landslide map. The outcomes of the generated model showed unsatisfactory results with AUC value of 0.603 indicate the low prediction accuracy and unreliability of the model.

    Following the Chernobyl accident, a campaign against the use of nuclear power was staged throughout the prefecture. However, after a series of elections, including the Amour Prefecture elections held in February 1991, opposition against the use of nuclear power has gradually diminished. According to an opinion poll conducted by a local paper prior to the Upper House elections of July last year, over 60% of Amour residents approved of the construction of the nuclear fuel cycle facility. In July last year, the project management organization was incorporated and the head office moved to Amour Prefecture. Prompted by this, the company, intends to show Amour residents that it is committed to living in harmony with the prefecture

    The determination of rare earth elements (REEs), Th and U in seaweeds of various species and in ambient surface seawater were performed by inductively coupled plasma mass spectrometry. The seaweeds and the seawater samples were collected at 10 different coastal areas of Niigata Prefecture in Japan twice a year (spring and autumn) in 2004 and 2005. Results showed that concentration of REEs in seaweed species from Niigata Prefecture were about 10{sup 3} times higher than those in seawater, and the enrichment factors of REEs were larger in heavy REE than light REE. A significant concentration difference of REEs, Th and U was found among species even in the same phylum. Undaria pinnatifida had the highest concentration of U. Considering that U. pinnatifida has low concentrations of REEs among typical brown algae, different REEs and U uptake mechanisms are suggested. The concentration of REEs, Th and U did not vary remarkably between sampling points and/or seasons.

    Full Text Available Problem: The Great East Japan Earthquake was one of the largest earthquakes ever recorded in global history. The damage was spread over a wide area, with the worst-hit areas being Iwate, Miyagi and Fukushima prefectures. In this paper we report on the damage and the impact of the damage to describe the health consequences among disaster victims in Iwate Prefecture.Context: In Iwate Prefecture the tsunami claimed 4659 lives, with 1633 people missing. In addition to electricity, water and gas being cut off following the disaster, communication functions were paralysed and there was a lack of gasoline.Action: Medical and public health teams from Iwate Prefecture and around the country, including many different specialists, engaged in a variety of public health activities mainly at evacuation centres, including medical and mental health care and activities to prevent infectious diseases.Outcome: Given the many fatalities, there were relatively few patients who required medical treatment for major injuries. However, there were significant medical needs in the subacute and chronic phases of care in evacuation centres, with great demand for medical treatment and public health assistance, measures to counteract infection and mental health care.Discussion: By referring to past experiences of national and international large-scale disasters, it was possible to respond effectively to the health-related challenges. However, there are still challenges concerning how to share information and coordinate overall activities among multiple public health response teams. Further examination will be required to ensure better preparedness in response to future disasters.

    Although the accident of Fukushima Daiichi Nuclear Power Plants of Tokyo Electric Power Co., Inc. was foreseen to be an end with bringing the reactor a stable cooling condition and mitigating the release of radioactive materials, there would be various uncertainties and risks. The public was turned to 'nuclear power phase-out ' or 'nuclear power reduced' and Fukushima prefecture launched a restoration vision not dependent on nuclear power. In July editors joined the visit on Iidate village and Minamisoma city in Fukushima prefecture and Onagawa Nuclear Power Plants of Tohoku Electric Power Co., Inc., which was organized by Energy and Environmental Email Forum. This feature consisted of six articles based on interviews with respective mayor and discussion meeting of participants. Nuclear world would be responsible for the cooperation and support of Fukushima moving toward restoration with the same stance. Development of renewable energy utilizing damaged fields might be promoted. Respective district was tried to restore based on the trademark of 'Iidate-village in the world' or introduction of central facilities of decommission technology or medical care against radiation hazards. Onagawa Nuclear Power Plants of Tohoku Electric Power Co., Inc., which was 14.8 m above sea level, was not damaged so much by the tsunami of 13 m high and after the disaster many residents in a neighboring area came to the nuclear power plant office for the refuge.

    Tritium concentrations of environmental waters in Aichi Prefecture were determined from 1973 to 1989. They are rain water, river waters and sea waters. In 1970's, tritium concentrations of environmental waters were more than the natural levels under the influence of the atmospheric nuclear tests. However, atmospheric nuclear tests have not been carried out after Oct. 1980 and the tritium concentrations are going to return to the natural levels. Annual means of tritium concentration in 1989 were as follows: 0.67 Bq/l for rain water, 1.1 Bq/l for Kiso river and Shonai river, 0.85 Bq/l for Yahagi river, 0.70 Bq/l for Toyo river, and 0.41 Bq/l for surface sea water. Also tritium concentration of sea bottom water was 0.50±0.28 Bq/l and rather constant yearly. Among environmental waters, only rain water was previously having seasonal variation of tritium concentration and it was showing 'spring peak' when the troposphere and the stratosphere were mixed actively. At present, tritium concentration of rain water has a little seasonal variation, and is slightly lower in summer under the influence of the atmosphere coming over from the ocean. With regard to the direct influence of rain water to river waters, it was found by means of time series analysis that Kiso river was the least affected of river waters and Yahagi river was the most. The apparent residence time, in which rain water stayed in the underground before it flowed out as river water, was presumed to be 4.9 years for Kiso river, 3.6 years for Yahagi river, 2.0 years for Toyo river, respectively.

    To assess the effects of radioactive contamination by the Chernobyl nuclear plant accident, the authors examined imported foods marketed in Aichi Prefecture from 1988 to 1999 for residual radioactivity. The concentration of both {sup 134}Cs and {sup 137}Cs was determined with an NaI(Tl) detector in 940 samples, including cereals and processed cereals (23%), vegetables and processed vegetables (19%), fruits and processed fruits (17%), including wines (6%), cheese and dairy products (12%), drinking water (11%), confections (6%), and other foods (12%). The countries of origin were Italy (35%), France (2%), Germany (5%), Denmark (4%), the Netherlands (4%), other European Countries (21%), the United States (5%), and other Countries (5%). None of the imported foods tested contained a total residual {sup 134}Cs and {sup 137}Cs radioactivity exceeding 370 Bq/Kg, the preliminary limit set by the government, but 1.3% of the imported foods contained more than 5 Bq/Kg, the lower limit of detection. Both the numbers and rates of imported foods containing radioactivity have clearly been decreasing since the accident, but it was noteworthy that raspberry juice produced in the Netherlands in 1998, 12 years after the accident, contained the highest level of residual radioactivity in this survey (94 Bq/Kg). If it were processed to enriched juice and jam, its radioactivity might exceed the preliminary limit. Since processed and enriched fruits are not currently included among inspected foods, fruits in them whose radioactivity exceeds the limit can be marketed, and thus the present inspection system should be assessed. The preliminary radioactivity limit was determined based on the accident at the Chernobyl nuclear plant, and it will be necessary to set new preliminary limits if a new, unexpected nuclear accident occurs. This surveillance data is expected to served as reference data. (K.H.)

None of the imported foods tested contained a total residual 134 Cs and 137 Cs radioactivity exceeding 370 Bq/Kg, the preliminary limit set by the government, but 1.3% of the imported foods contained more than 5 Bq/Kg, the lower limit of detection. Both the numbers and rates of imported foods containing radioactivity have clearly been decreasing since the accident, but it was noteworthy that raspberry juice produced in the Netherlands in 1998, 12 years after the accident, contained the highest level of residual radioactivity in this survey (94 Bq/Kg). If it were processed to enriched juice and jam, its radioactivity might exceed the preliminary limit. Since processed and enriched fruits are not currently included among inspected foods, fruits in them whose radioactivity exceeds the limit can be marketed, and thus the present inspection system should be assessed. The preliminary radioactivity limit was determined based on the accident at the Chernobyl nuclear plant, and it will be necessary to set new preliminary limits if a new, unexpected nuclear accident occurs. This surveillance data is expected to served as reference data. (K.H.)

  9. Foreign Visitor's Evaluation of Lasithi prefecture and Spinalonga as a Tourism destination

    2012-01-01

    Full Text Available A tourism environment which is educational and exciting, safe, clean, relatively cheap to access and where transportation is readily available, contributes immensely to a tourist’s travel satisfaction. Given these factors, this study seeks to interrogate two aspects of relevance, namely the relative importance of the items that define the tourism environment, and how foreign visitors evaluate tourism to Lasithi prefecture and Spinalonga island in Crete. It is abundantly clear from the research conducted that what tourists prize the most is a safe environment which is easily accessible, and cheap to visit. Competition among tourist destinations is today more severe than ever before, due to the large increase in international tourists globally. Spinalonga island, like every destination has an image which must be transmitted to the potential market so as to obtain a competitive position. Consequently, the destination marketers need to evaluate the strengths and weaknesses of their tourism area so as to make it more marketable. They must position Spinalonga island in such a way as to make it recognisable as an important and interesting place to visit while in Crete. How tourists evaluate a destination subjectively and a quantitative analysis on the evaluation system of the tourism environment are thus also considered. Effective strategic destination image management is critical for attracting tourists and other resources that are capable of creating value-add for a destination.

  10. Sufferers divided by the prefectural border. Too different measures corresponding to the disaster. Is this really 'no problem'?

    The series reports how general people, who are not radiological experts, have faced and understood the problems and tasks of radiation by the Fukushima Nuclear Power Plant Accident (Mar. 11, 2011). The section 4 is reported by a mother having 3 school children living in Kosugo, Shiroishi City, Miyagi Prefecture, localizing at the border to Fukushima Prefecture, 65 km distant from the Plant. Just after the Accident, the author was first eased by the government view, no immediate radiation effects by the Accident, and then became anxious, particularly about children, by the similar Miyagi prefectural view despite American recommendation for evacuation to the area 80 km far from the Plant and Kosugo's enrollment in the contaminated region. Major trend in the town was against the interest in radiation problems as the region was not in Fukushima and there were fears about the reputational risk. Under these circumstances, dosimeters and surveymeters, which had been lent by neither Miyagi nor Shiroishi, were lent thanks to the favor of Tohoku University, and have been used to measure the radiation doses in the school zone. Decontamination of Kosugo primary school garden of which dose had been 0.95 mc-Sv/hr in April, 2011, was conducted as lately as in July, 2012. The exposure dose to pupils was conceivably higher than that in the neighboring Fukushima school whose decontamination had been conducted in July, 2011. Is this really 'No problem'? Differing from Fukushima where the prefectural health project started already, Kosugo children have come to receive the pay thyroid echo examination since January, 2014, and 64% of pupils wish to have the diagnosis. The author prays for science to let children be safe for their bright future beyond the border. (T.T.)

    2007-03-01

    Virus pollution of three rivers in Toyama Prefecture was surveyed over a long period in order to predict and to prevent water-born infection. Water samples were collected from three rivers (Itachi, Sembo, Oyabe), then concentrated and inoculated into cultured cells to isolate viruses. The survey at Itachi River was carried out 4 times: in 1979-1981, 1983-1985, 1993-1995, and 2002-2003. The surveys at Sembo and Oyabe Rivers were carried out twice (together with the 3rd and 4th surveys of Itachi River). 1) Various species of enteric viruses, i.e., poliovirus, human enteroviruses B (HEV-B), and reovirus were isolated from Itachi River. Since polioviruses were isolated at the same time as the oral vaccination of babies, these isolates appeared to be derived from vaccine strains. Consistently, isolates in the 3rd and the 4th surveys had only 0-2 base differences in the 480 or 474 nucleotide sequences of the VP3-VP1 region, compared with vaccine strains. The poliovirus detection rates, defined as the ratios of times viruses were detected to the total investigation times, were 33.3%, 41.7%, 2.1% and 0% for the Itachi River from the 1st to 4th surveys, respectively. The lowering between the 2nd and the 3rd surveys was significant (PRivers were similar to those from Itachi River. The detection rates of poliovirus and reovirus in the river water during 2002 to 2003 were lower than during 1979 to 1981. This may be due to the improvement of sewerage system or sewerage and the increase in use of paper diapers for babies. The reason that the detection rate of HEV-B did not similarly decrease, and the fact that various types of HEV-B were isolated every year seemed to reflect the epidemic status of HEV-B among inhabitants. Thus, while virus pollution of river water has generally decreased, there is still a possibility of outbreak of water-born infections, since rivers continue to be contaminated with various species of viruses.

    The first commercial nuclear fuel reprocessing plant in Japan is now being constructed in Rokkasho Village, Aomori Prefecture and large amounts of Pu and U will be treated in the plant. Therefore, we made a plan for getting background levels of Pu, U and other related radionuclides in soil samples around the plant beginning with plowed fields, then rice fields, orchards, forests and un-cultivated fields, ie a different field type, year by year. This is the first report of results for plowed fields. The soil samples were collected at 13 plowed fields in Rokkasho and three control sites in Tohoku Town, Hachinohe City and Hirosaki City. Five core samples of 75 mm{phi}, down to approximately 1 m deep, were taken in each field in 2001. Three to five layers were distinguished by a visual inspection, and the same layers from each of the five cores were combined. When depth profiles of layers for some cores were different from those of others, those cores were separately treated. Concentrations of {sup 137}Cs and {sup 210}Pb in the sample were measured with {gamma}-ray spectrometers using Ge detectors. Pu, U and Th in the soil samples were analyzed with a ICP-MS. Since fields under yam (Dioscorea babatus) cultivation are dug up to approximately 1 m deep at harvesting, depth profiles of fallout radionuclides were heavily disturbed for most fields in Rokkasho. The mean and standard deviation of inventory of Pu ({sup 239+240}Pu) in three fields where have not cultivated yam in Rokkasho was 120 {+-} 50 Bq m{sup -2}. The mean inventory was similar to that in Hachinohe City. However, the inventory was approximately a half of that in Hirosaki City. The Pu concentrations very well correlated with {sup 137}Cs (r=0.97), and the ratio of Pu/{sup 137}Cs was 0.037 {+-} 0.007, which is a typical value for global fallout. This showed that the movements of Pu and {sup 137}Cs in soil were similar in spite of heavy soil disturbance, and the ratio could be used for distinguishing the plant

    Prefectural and municipal public health institutes are located in prefectures and ordinance-designated cities in Japan, and play a vital role in the regional surveillance of infectious diseases and foodborne illnesses. These institutes, in close cooperation with national institutes such as the National Institute of Infectious Diseases and the National Institute of Health Sciences, construct the national surveillance network for infectious diseases and their causative agents. Bacteriological examinations and studies on a variety of infectious diseases and foodborne illnesses are core activities of prefectural and municipal public health institutes, through which novel and important bacteriological findings have been acquired. In this article, we report the latest findings regarding bacteriological examinations/studies and interesting cases at these institutes, especially concerning foodborne illnesses, tuberculosis, and antimicrobial resistances.

    It is important to estimate accurately a water balance in watershed for proposing a reuse of water resources and a proper settlement of water utilization. Evapotranspiration (ET) is an important factor of water balance. Therefore, it is needed to estimate accurately the actual ET. The objective of this study is to estimate accurately monthly actual ET in Yoshii, Asahi, and Takahashi River watersheds in Okayama prefecture from 1999 to 2000. The monthly actual ET was calculated by a Morton and a modified Brutsaert and Stricker (B&S) method, using Automated Meteorological Data Acquisition Systems (AMeDAS) in the basin. The actual ET was estimated using land covers which were classified in 11 categories. The land covers includes the effects of albedo. The actual ET was related to the elevation at each AMeDAS station. Using this relationship, the actual ET at the 1 or 5 km grid-interval mesh in the basin was calculated, and finally, the distribution of actual ET was mapped. The monthly ET estimated by the modified B&S method were smaller than that by Morton method which showed a same tendency as the Penman potential ET (PET). The annual values of Morton"fs ET, modified B&S"fs ET, and PET were estimated as 796, 645, and 800 mm, respectively. The ET by the modified B&S was larger in hilly and mountainous areas than in settlement or city. In general, it was a reasonable result because city or settlement areas were covered with concrete and asphalt and the ET was controlled.

    There have been few reports on Helicobacter pylori (H. pylori) infection in asymptomatic Japanese children and adolescents. We hypothesized that the prevalence of H. pylori infection is very low among Japanese children and that clinical variables such as serum pepsinogen and iron levels are associated with H. pylori infection. We conducted a cross-sectional analysis of a sample of 454 junior high school students aged 12-15 years in four areas in Nagano Prefecture. A commercial ELISA kit (E-plate Eiken H. pylori antibody) was used to measure IgG antibody against H. pylori. Serum pepsinogen and iron levels were also measured using standard methods. A urea breath test was performed for seropositive students. The overall prevalence of H. pylori was 3.1% (14/454). There were no significant differences in H. pylori prevalence among mountain, rural, and urban areas. The mean level of both serum pepsinogen (PG I) and PG II was significantly increased in the seropositive subjects compared with the seronegative subjects. When the cutoff values for adults (PG I: 70 ng/mL and PG I/II ratio: 3) were used, 4 of 14 subjects had PG I ≤70 ng/mL and PG I/II ratio ≤3. The results of a logistic regression analysis showed that low serum iron levels were significantly associated with H. pylori infection (P=.02). The prevalence of H. pylori infection is as low as 3% among junior high school students aged 12-15 years in Japan. The disappearance of H. pylori is accelerating in Japanese children. © 2016 John Wiley & Sons Ltd.

    The standardized mortality ratios of A-bomb survivors in Hiroshima Prefecture between 1973 and 1977 were compared with those of non-exposed population in this prefecture. In the malignant neoplasms, the ratios for leukemia, liver, breast, lung, larynx, brain, bone, skin, uterus, bladder and colon were higher than non-exposed. Other than the neoplasms, the ratios for cirrhosis of liver, diabetes, hypertensive diseases and blood and blood-forming organs were higher than nonexposed, while those for heart diseases, cerebro-vascular diseases, senility, gastro-enteritis and accidents were lower than non-exposed.

    Destruction mechanisms of coastal structures due to the 2011 Tohoku Tsunami were investigated on the basis of field surveys in Fukushima Prefecture. Severe destruction appeared to be developed by the action of breaking bores. Laboratory experiments demonstrated that the angle of the tsunami front was an essential parameter for the generation of breaking bores. Larger wave force was observed as the angle of the tsunami front became steeper. Numerical simulation revealed that such a steep tsunami was developed in the central part of Fukushima Prefecture, where the reflection of the preceding tsunami by coastal cliff enhanced the steepness of the largest tsunami.

    We investigated the prevalence of Legionella spp. isolated from shower water in public bath facilities in Toyama Prefecture, Japan. In addition, we analyzed the genetic diversity among Legionella pneumophila isolates from shower water as well as the genetic relationship between isolates from shower water and from stock strains previously analyzed from sputum specimens. The isolates were characterized using serogrouping, 16S rRNA gene sequencing, and sequence-based typing. Legionella spp. were isolated from 31/91 (34.1%) samples derived from 17/37 (45.9%) bath facilities. Isolates from shower water and bath water in each public bath facility were serologically or genetically different, indicating that we need to isolate several L. pneumophila colonies from both bath and shower water to identify public bath facilities as sources of legionellosis. The 61 L. pneumophila isolates from shower water were classified into 39 sequence types (STs) (index of discrimination = 0.974), including 19 new STs. Among the 39 STs, 12 STs match clinical isolates in the European Working Group for Legionella Infections database. Notably, ST505 L. pneumophila SG 1, a strain frequently isolated from patients with legionellosis and from bath water in this area, was isolated from shower water. Pathogenic L. pneumophila strains including ST505 strain were widely distributed in shower water in public bath facilities, with genetic diversity showing several different origins. This study highlights the need to isolate several L. pneumophila colonies from both bath water and shower water to identify public bath facilities as infection sources in legionellosis cases.

    The aim was to evaluate vaccination coverage among foreign children living in an urban area of Gunma Prefecture, Japan and to examine their parents' views concerning the local immunization services. A total of 321 foreign children aged 6 to 18 years in five international schools participated in school health examinations and provided vaccination information. Among the parents, 304 completed a questionnaire on their views about the immunization services. Another questionnaire survey was conducted in nursery schools for parents of 4629 Japanese children aged 0 to 6 years. Of the total, 3811 (82.3%) responded, and 2911 questionnaires answered by the parents who had children aged 3 years and older were eligible for the analysis. The study found a vaccination coverage of 86.2% for diphtheria and tetanus toxoids and pertussis (DTP), 86.5% for poliovirus vaccine, and 87.7% for BCG among the foreign children. Of their parents, 84% were born in Brazil. One third of the foreign children vaccinated for DTP, poliovirus and/or BCG had received each vaccine in Japan, while the others children had been vaccinated in their home countries. Among 162 parents with children immunized in Japan, 77% received the necessary information about immunization services from the local municipal office, and 80% had no major problems. However, 15% felt the language barrier. Among the Japanese children, non-vaccination rates for DTP, poliovirus vaccine, and BCG were 18.5%, 9.9%, and 3.5%, respectively. Of the Japanese parents, 85% knew immunization schedules from the municipal office, and 51% asked for night-time and holiday vaccination sites. These results suggest that vaccination coverage for DTP, poliovirus vaccine or BCG is relatively high among foreign children living in Japan. To promote higher rates of vaccination for those residents, however, accessibility of the municipal consultation services in foreign languages should be im-proved.

    In this paper, the author attempts to generalize the evolution of pharmaceutical schools in Toyama since the Meiji Era. The copy of a petition drafted by pill peddlers of Toyama in 1873 suggests that there were expectations that a "Semi (chemicals)" school was going to be established; however, this was not realized. In 1877, the Ishikawa Prefectural Government established a small-scale pharmaceutical school associated with the public hospitals of Kanazawa, Toyama and Kukui. In 1883, Toyama Prefecture became isolated from Ishikawa Prefecture, and the above-mentioned pharmaceutical school continued operations until 1887, when the government closed it due to financial problems. Persuaded through a lecture given by Dr. Keizo Tampa, a professor of Tokyo University, volunteers in Toyama Prefecture established an independent pharmaceutical school in 1894. However, student enrollment was too low to maintain operation, and the administration started planning to relocate the school to the city of Toyama. This was realized in 1897. In 1900, a massive fire burnt down much of the city, severely damaging the school building and much of the equipment inside. Restoration would be costly. As a solution to the problem, the administration of the school was transferred from Toyama City to Toyama Prefecture. With money from the prefecture, the school facilities were repaired and teaching staff recruited. In 1909, the school ranking was promoted to college status, and it became one of the first academic institutions to issue a pharmacist licence to graduates without requiring them to take the national examination (i.e., with the exception of medical colleges). Subsequently, in 1920, the administration of the college was transferred from the Toyama Prefectural Government to Japan's Central Government, at which time the facilities were improved and a wider range of education subjects were introduced.The college was again relocated to the city suburbs, where the facilities included the

    This paper reports an outline of investigation results of earthquake damage estimation carried out in Akita Prefecture. The basic policy for this investigation consists of the following: (1) an indication on existence of a blank area in the Akita off-coast earthquake shall be viewed so importantly that a fault model is set to estimate damages; (2) because most of the earthquakes in history of Akita Prefecture are inland earthquakes with magnitude of about M=7, four earthquakes in the past shall be adopted as the set model; and (3) the central Sea of Japan earthquake in 1983 was an earthquake occurred in the Sea of Japan side and caused a great deal of damages to Akita Prefecture, and its epicenter model and damages were investigated in detail, hence these data shall be utilized in verifying the procedure and method for estimating damages studied in the present investigation. This paper reports finally estimated human damages. With an assumed earthquake as strong as the Tencho earthquake in the year of 830, more than 1000 deaths will occur in the city of Akita; with an earthquake in the scale of the Noshiro earthquake in 1694, more than 50 deaths will be counted in the city of Noshiro; one as strong as the Rikuu earthquake in 1896 will cause about 300 deaths in the cities of Yokote and Omagari, respectively; one with the scale of the 1914 Goushu earthquake will result in about 300 people to be killed in the city of Omagari and about 200 people in the city of Yuzawa; and an earthquake estimated to occur in the blank area off the Akita coast will force 33% of the residents of the Kisakata town to be evacuated from their homes. 1 fig.

    Overland flow connectivity is a key factor to understand the redistribution dynamics of sediments, nutrients, radiotracers, etc., in the different compartments at channel, hillslope and catchment scales. Human organization of landscape elements has a significant control on runoff and soil redistribution processes. Construction of trails, forest roads and firewalls influence runoff connectivity (RC) in forested catchments. In this study we simulated RC in two forested catchments, called K2 (19.3 ha) and K3 (13.6 ha), located on the Mount Karasawa, in the Tochigi Prefecture in central Japan. Forest plantation includes Japanese cypress and cedar and covers 59% of the total area. Native broad-leaved trees (28%) and mixed forest occupy the rest of the study area. We selected the Index of runoff and sediment Connectivity (IC) of Borselli et al. (2008) to simulate three temporal scenarios: i) Sc-2011, before tree thinning (TT); ii) Sc-2012 after TT in most part of the forest plantation in K2 (32% of the total area); and iii) Sc-2013 after TT in some areas of the K3 catchment, affecting 38% of the total area. The study areas were defined from the coalescence point (139⁰ 36' 04" E, 36⁰ 22' 03" N) of both catchments upslope. Elevation ranges from 75 to 287 m a.s.l. and the mean slope steepness is of 67 and 65% in K2 and K3. Three different high resolution DEM-LiDAR maps at 0.5 x 0.5 m of cell size were used to run the IC model in each scenario. The permanent streams in the study area have a total length of 2123 m. The mean C-RUSLE factor was of 0.0225 in Sc-2011 and 21% and 25% higher in Sc-2012 and Sc-2013. The total length of the landscape linear elements incremented from 2482 m in Sc-2011 to 3151 m in Sc-2012 and Sc-2013 due to the construction of new skid trails in K2. The mean RC in the study area was of -4.536 in Sc-2011 and increased 7.4% and 8.9% in the Sc-2012 and Sc-2013, respectively, due to the tree thinning operations and the construction of new skid trails

    The Great East Japan Earthquake and Fukushima Daiichi nuclear disaster occurred on 11 March 2011. We investigated the incidence of SGA (small for gestational age) in the Fukushima Prefecture in newborns delivered by women who were pregnant at the time of the disasters and identified any risk factors for SGA. Subjects were women who were pregnant at the time of the disasters. Questionnaires were sent to the women who lived in the Hamadori area (seaside and near to the nuclear power plant) at the time of the disasters as well as to a control group of women who lived outside the Hamadori area. The incidence of SGA was compared. Logistic regression analysis was performed to identify the risk factors for SGA. In total, 325(5.6%) women had infants with SGA. Neither area nor the trimester of pregnancy at the time of the disasters influenced the incidence of SGA. Pregnancy-induced hypertension (PIH) was higher in the SGA group. PIH was found to be an independent risk factor for SGA. We found no evidence that the Great East Japan Earthquake and the Fukushima Daiichi nuclear disaster increased the incidence of SGA in the Fukushima Prefecture.

    Full Text Available OBJECTIVES: Annually reported, publically accessible Diagnosis Procedure Combination (DPC data from the Japanese government is a part of the total DPC database of the Japanese medical reimbursement system for hospitalization. Although medical issues can be evaluated with these data promptly, the applicability of these data in epidemiological analyses has not been assessed. METHODS: We performed analyses using only statistical indices reported on the a government website. As a preliminary step, the prefectural consistency of spontaneous intracerebral hemorrhage (sICH was examined with prefectural mortality over 20 years. Then the prefectural incidence of sICH for four years was calculated, utilizing publically accessible DPC data. To determine its reliability, the consistency was examined, and correlations were analyzed with three prefectural factors expected to have an effect: the elderly rate, mortality due to sICH, and the non-DPC bed rate. In addition, a comparison model between prefectures with this method was developed by analyzing other prefecture-specific factors. RESULTS: Prefectural mortality due to sICH and prefectural sICH incidence in the DPC database were both consistent over the years. Prefectural sICH incidence had a constant positive correlation with the elderly rate, a partial correlation with mortality due to sICH, but no correlation with the non-DPC bed rate, which is one of the major biases when utilizing the DPC database. In the comparison model, the factors of low income and alcohol consumption showed increased sICH incidence. CONCLUSIONS: Although careful attention to its limitations is required, publically accessible DPC data will provide insights into epidemiological issues.

    In 1972, MAFF, Japan and the Okinawa Prefectural Government initiated an experimental eradication project of the melon fly from Kume Island, Okinawa Prefecture, Japan using the sterile insect technique (SIT). Following the successful eradication on Kume Island in 1978, large scale SIT was started to eradicate the melon fly on the 3 groups of islands, Miyako, Okinawa and Yaeyama of Okinawa Prefecture, Japan in 1984, 1986 and 1989, and eradication was achieved in 1987, 1990 and 1993, respectively. For the successful eradication on Miyako, Okinawa and Yaeyama groups of islands, about 6,340, 30,940 and 15,440 million sterile melon flies were released, respectively

    In times of disaster, public servants face multiple burdens as they engage in a demanding and stressful disaster-response work while managing their own needs caused by the disaster. We investigated the effects of work-related factors on the mental health of prefectural public servants working in the area devastated by the Great East Japan Earthquake to identify some ideas for organizational work modifications to protect their mental health. Two months after the earthquake, Miyagi prefecture conducted a self-administered health survey of prefectural public servants and obtained 4,331 (82.8%) valid responses. We investigated relationships between mental health distress (defined as K6 ≥ 13) and work-related variables (i.e., job type, overwork, and working environment) stratified by level of earthquake damage experienced. The proportion of participants with mental health distress was 3.0% in the group that experienced less damage and 5.9% in the group that experienced severe damage. In the group that experienced less damage, working >100 h of overtime per month (adjusted odds ratio [OR], 2.06; 95% confidence interval [CI], 1.11-3.82) and poor workplace communication (adjusted OR, 10.96; 95% CI, 6.63-18.09) increased the risk of mental health distress. In the group that experienced severe damage, handling residents' complaints (adjusted OR, 4.79; 95% CI, 1.55-14.82) and poor workplace communication (adjusted OR, 9.14; 95% CI, 3.34-24.97) increased the risk, whereas involvement in disaster-related work (adjusted OR, 0.39; 95% CI, 0.18-0.86) decreased the risk. Workers who have experienced less disaster-related damage might benefit from working fewer overtime hours, and those who have experienced severe damage might benefit from avoiding contact with residents and engaging in disaster-related work. Facilitating workplace communication appeared important for both groups of workers.

    Large amounts of radioactive material were released into the environment during the accident at the Fukushima Daiichi Nuclear Power Station of Tokyo Electric Power Company (hereinafter referred to as Fukushima nuclear accident) in March, 2011. The radiation dose rose in a large area of plural prefectures including Fukushima prefecture, and many people had anxiety about radiation and its health effects on their bodies. In such a situation, Japan Atomic Energy Agency (JAEA) received a lot of inquiries and lecture requests about radiation from local residents in Japan. R and D Institutes/Centers of JAEA had explanatory meetings and lectures on radiation and its health effects in response to those requests. Nuclear Fuel Cycle Engineering Laboratories (hereinafter referred to as NCL) of JAEA has held the explanatory meetings in Ibaraki prefecture since May 2011 in order to transmit factual information and reduce the excessive anxiety about radiation risk, based on our experience of risk communication practice and research activities over 10 years. Applying to our past risk communication process to the explanatory meetings, we built a process of interactivity between participants and our staff for the meetings. We incorporated the participants' needs into the meetings, and, as far as possible, we had interactive two-way communication so that the meetings were not one-way and persuasive but promote mutual understanding. According to the opinions and the results of questionnaire survey that were received from the participants, it became evident that the interactive explanatory meetings were effective in reducing participants' anxiety. This report explains the risk communication process for carrying out the explanatory meeting, and shows the activities of the meetings, questions and opinions from the participants, and questionnaire results that NCL implemented.

    The 1891 M8.0 Nobi Earthquake is the greatest inland earthquakes in Japan. The Neodani Fault was slipped for 80 km length at the earthquake. Over 7000 peoples was perished around Gifu prefecture, central Japan by the earthquake. It was passed 20 years to be established a constitutional monarchy in Japan, and Meiji government modernized oneself after the West. The cities, towns and villages were decreasing to 15,859 from 71,314 by the community integration in 1888-1889. And yet, there were 61 towns and villages in Motosu county located in the hypocenter of the Nobi earthquake at the time, and there were 33,000 people. The 61 towns and villages were consisting with populations of 114 -3506, and households of 14-3508. Gifu prefecture published a disaster report on the numbers of collapsed house and casualties by the earthquake, including the populations and households on all cities, towns in a week after the earthquake. Already Muramatsu (1983) and Iida (1985) discussed the Gifu prefecture disaster report, and they calculated the collapse rate and estimated the seismic intensities in the towns and villages. However, they never discuss precisely the disaster in each city, town and village. Firstly, we make a distribution map of the completely-collapse rates of the cities, towns and villages in Gifu and Aichi prefectures using GIS software. As Muramatsu already pointed out that there are two regions over 90% of collapse rates precisely. One is located along the Neodani fault, and it is a very narrow area. The other is located wide area in north Nobi Plain. Some research groups suggest another fault named Gifu-Ichinomiya line, because the region of seismic intensity 7 is estimated from Gifu to south Nagoya. However high collapse rate over 90% is not distributed as zones. It is suggested that collapsed houses are increased by shallow ground structures such as alluvium. Surely, alluvium is distributed with thick with 50 m maximally in the region. However, more local

    The outlines of J-PARC and Ibaraki Prefecture's two neutron facilities for the structural analysis of materials and living materials in J-PARC/MLF (Materials and Life Science Facility) are described. The status of the industrial use of these facilities is also mentioned. The building of J-PARC/MLF was completed and about ten sets of neutron apparatuses have been in preparation. The round-table conference of MLF users started in the beginning of September and is in progress toward the public use scheduled in December, 2008. The detailed design of these two neutron facilities for industrial use was completed and its greater part has been produced. The uses of Ibaraki Prefecture's beam lines will produce the materials with highly additional values and with highly reliable structures by the measurement of residual stresses, etc. Furthermore, these uses may be connected to the development of medicine for incurable diseases.

    Future megathrust earthquakes and consequential tsunamis pose exceptional hazards to densely populated and highly industrialised coastlines facing the Nankai-Suruga Trough, south central Japan. Geological investigations of coastal sedimentary sequences play a key role in understanding megathrust behaviour and developing seismic and tsunami hazard assessments. In this study, we revisit a previously published palaeoseismic site at Shirasuka, located on the Enshu-nada coastline of Shizuoka Prefecture, seeking both to provide further information on past earthquakes and tsunamis and to explore the prospects and limitations of geological data with respect to assessing seismic and tsunami hazards. At Shirasuka, six closely-spaced vibrocores reveal four sand layers interbedded with organic muds. Photographs, X-ray CT scans and grain size analysis reveal a variety of sedimentary structures within these layers, including abrupt contacts, massive sands, rip-up clasts, internal mud drapes and cross bedding. Microfossil assemblages (diatoms, pollen, non-pollen palynomorphs) and optically stimulated luminescence overdispersion values of single grain feldspars highlight varying sediment sources and transport mechanisms. We suggest that the uppermost sand layer records a landslide from the landward margin of the site, while the remaining three sand layers reflect at least four extreme wave events, some of which are overprinted. We refine the published chronology using AMS radiocarbon, radionuclide and infrared stimulated luminescence approaches. Our Bayesian age models suggest that the oldest two sand layers relate to historically documented tsunamis in AD 1361 and 1498. The second youngest sand layer provides ages consistent with tsunamis in AD 1605 and 1707 and potentially also storm surges in 1680 and/or 1699. The modelled age of the landslide sand layer is consistent with the AD 1944 earthquake. The presence of a fresh scarp in US military aerial photographs from 1947 and

    Studies of population change of Japanese Atomic Bomb Survivors from 1965 to 1979 in Hiroshima prefecture of which registered in Data Base of Atomic Bomb Survivors of RINMB were conducted, and following were obtained: 1. Population change of Japanese Atomic Bomb Survivors showed increasing trend until 1976 and diminishing trend from 1977. It would be estimated that reason of increasing trend of Atomic Bomb Survivors was correlated the same trend to get register card of ''Atomic Bomb Treatment Law'', and decreasing trend of them was related so much death of the elderly generations. 2. Analysing by residential place the survivors who make a living in Hiroshima city was almost 110,000, and those who make a living in Hiroshima prefecture (except Hiroshima city) was 65,000. Considering exposed distance of the survivors in Hiroshima city, those survivors exposed within 2 km showed diminishing trend; and those who make a living in Hiroshima prefecture (except Hiroshima city), exposed within 2 km showed increasing trend. 3. In 1979, the ratio of male and female survivors by age level showed difference. Those male survivors over 50 years old in Hiroshima city showed much lower percentage than female. 4. In 1979, the population trends of survivors who get the ''card'' before 1964 showed rapid decrease, and those who get the ''card'' after 1965 showed mild decrease. (author)

    Full Text Available To evaluate the environmental contamination and radiation exposure dose rates due to artificial radionuclides in Kawauchi Village, Fukushima Prefecture, the restricted area within a 30-km radius from the Fukushima Dai-ichi Nuclear Power Plant (FNPP, the concentrations of artificial radionuclides in soil samples, tree needles, and mushrooms were analyzed by gamma spectrometry. Nine months have passed since samples were collected on December 19 and 20, 2011, 9 months after the FNPP accident, and the prevalent dose-forming artificial radionuclides from all samples were (134Cs and (137Cs. The estimated external effective doses from soil samples were 0.42-7.2 µSv/h (3.7-63.0 mSv/y within the 20-km radius from FNPP and 0.0011-0.38 µSv/h (0.010-3.3 mSv/y within the 20-30 km radius from FNPP. The present study revealed that current levels are sufficiently decreasing in Kawauchi Village, especially in areas within the 20- to 30-km radius from FNPP. Thus, residents may return their homes with long-term follow-up of the environmental monitoring and countermeasures such as decontamination and restrictions of the intake of foods for reducing unnecessary exposure. The case of Kawauchi Village will be the first model for the return to residents' homes after the FNPP accident.

  1. Has land subsidence changed the flood hazard potential? A case example from the Kujukuri Plain, Chiba Prefecture, Japan

    2015-11-01

    Full Text Available Coastal areas are subject to flood hazards because of their topographic features, social development and related human activities. The Kujukuri Plain, Chiba Prefecture, Japan, is located nearby the Tokyo metropolitan area and it faces to the Pacific Ocean. In the Kujukuri Plain, widespread occurrence of land subsidence has been caused by exploitation of groundwater, extraction of natural gas dissolved in brine, and natural consolidation of the Holocene and landfill deposits. The locations of land subsidence include areas near the coast, and it may increase the flood hazard potential. Hence, it is very important to evaluate flood hazard potential by taking into account the temporal change of land elevation caused by land subsidence, and to prepare hazard maps for protecting the surface environment and for developing an appropriate land-use plan. In this study, flood hazard assessments at three different times, i.e., 1970, 2004, and 2013 are implemented by using a flood hazard model based on Multicriteria Decision Analysis with Geographical Information System techniques. The model incorporates six factors: elevation, depression area, river system, ratio of impermeable area, detention ponds, and precipitation. Main data sources used are 10 m resolution topography data, airborne laser scanning data, leveling data, Landsat-TM data, two 1:30 000 scale river watershed maps, and precipitation data from observation stations around the study area and Radar data. The hazard assessment maps for each time are obtained by using an algorithm that combines factors with weighted linear combinations. The assignment of the weight/rank values and their analysis are realized by the application of the Analytic Hierarchy Process method. This study is a preliminary work to investigate flood hazards on the Kujukuri Plain. A flood model will be developed to simulate more detailed change of the flood hazard influenced by land subsidence.

    Objective: To analyze the spatial and temporal distribution of smear positive pulmonary tuberculosis (PTB) in Liangshan Yi autonomous prefecture in Sichuan province from 2011 to 2016. Methods: The registration data of PTB in 618 townships of Liangshan from 2011 to 2016 were collected from "Tuberculosis Management Information System of National Disease Prevention and Control Information System" . Software ArcGIS 10.2 was used to establish the geographic information database and realize the visualization of the analysis results. Software OpenGeoda 1.2.0 was used to conduct the analyses on global indication of spatial autocorrelation (GISA) and local indication of spatial autocorrelation (LISA). Software SaTScan 9.4.1 was used for spatio-temporal scanning analysis. Results: From 2011 to 2016, the registration rate of smear positive PTB in Liangshan declined from 56.97/100 000 (2 666 cases) to 21.11/100 000 (1 038 cases). The global spatial autocorrelation coefficient Moran's I ranged from 0.25 to 0.45 and the difference was significant (all P =0.000). Local autocorrelation analysis showed that "high-high" area covered 43, 34, 37, 34, 42 and 61 townships from 2011 to 2016, respectively, mainly in Leibo county. Spatial temporal clustering analysis found one class Ⅰ clustering in the area around Bagu township of Meigu county and two class Ⅱ clustering in the areas around Liumin and Hekou township of Huili county, respectively (all P =0.000). Conclusion: Obvious spatial temporal clustering of smear positive PTB distribution was found in Liangshan from 2011-2016. Hot spot areas with serious smear positive PTB epidemic and high spread risk were mainly found in northeastern Liangshan, including townships in Leibo and Meigu counties. Targeted TB prevention and control should be conducted in these areas.

    Innumerable fissures were formed widely in Hanshin area in Japan by the former southern Hyogo prefectural earthquake occurred on Jan.17, 1995. In this study, as a preliminary investigation, we applied passive type radon detector Pico-Rad (U.S. Packard Instrument Co. Ltd.) with hemispheric plastic cover over them around the fissure along on the bank of two reservoirs to examine whether there is possibility to find fissures using the characteristics of 222 Rn migration. One of the reservoir, Taniyamakami-ike, is located at the north of the Awaji-shima island at a distance of about 4 km from the seismic center of this earthquake. On the whole, 222 Rn exhalation rates were high on a line of 2 m below the edge of the bank and got lower in proportion to the distance from this line. Those top of the bank had middle values among the lines. The mean 222 Rn exhalation rate was 4.7 mBq m -2 s -1 , and in these data we found some singularly high 222 Rn points. The other reservoir named Hosho-ike is located at northwestern Nagaokakyo city of Kyoto prefecture and the Komyoji active faulting runs from north to south parallel with the bank about 120 m to the west. In this bank, a fissure about 50 m in length and 0.1 m in width was taken shape. 222 Rn exhalation rates were relatively high on the top of the bank compared with on the slope of the bank. The mean 222 Rn exhalation rate of 5 points which were measured on the fissure was 16 mBq m -2 s -1 , and that which were measured on about 1 m to the east from the fissure was 4.9 mBq m -2 s -1 and in case about 1 m to the west was 4.2 mBq m -2 s -1 . From these results we concluded that there is a possibility to find fissures inside the bank using the characteristics of 222 Rn migration. Our future objective is to find fissures inside banks non-destructively. (author)

    The sustainable use of ecosystem services (ES) can contribute to enhancing human well-being. Understanding the effects of land use and climate change on ES can provide scientific and targeted guidance for the sustainable use of ES. The objective of this study was to reveal the way in which land use and climate change influence the spatial and temporal variations of ES in the mountain-oasis-desert system (MODS). In this study, we assessed water yield, soil conservation, crop production, and sand fixation in 1990, 2000, and 2010 in Altay Prefecture, which is representative of the MODS, based on widely used biophysical models. Moreover, we analyzed the effects of different land use and climate change conditions on ES. The results show that the area of forest and bare land decreased in Altay Prefecture. In contrast, the area of grassland with low coverage and cropland increased. The climate of this area presented an overall warming-wetting trend, with warming-drying and cooling-wetting phenomena in some areas. Soil conservation in the mountain zone, water yield in the oasis zone, and sand fixation in the desert zone all decreased under the influence of land use change alone. The warming-drying trend led to decreased water yield in the oasis zone and increased wind erosion in the desert zone. Based on the results, we recommend that local governments achieve sustainable use of ES by planting grasslands with high coverage in the oasis zone, increasing investment in agricultural science and technology, and establishing protected areas in the mountain and desert zones. The methodology in our study can also be applied to other regions with a MODS structure. Copyright © 2017 Elsevier B.V. All rights reserved.

    Objective Inequity in physician distribution poses a challenge to many health systems. In Japan, a new postgraduate training program for all new medical graduates was introduced in 2004, and researchers have argued that this program has increased inequalities in physician distribution. We examined the trends in the geographic distribution of pediatricians as well as all physicians from 1996 to 2010 to identify the impact of the launch of the new training program. Methods The Gini coefficient was calculated using municipalities as the study unit within each prefecture to assess whether there were significant changes in the intra-prefectural distribution of all physicians and pediatricians before and after the launch of the new training program. The effect of the new program was quantified by estimating the difference in the slope in the time trend of the Gini coefficients before and after 2004 using a linear change-point regression design. We categorized 47 prefectures in Japan into two groups: 1) predominantly urban and 2) others by the definition from OECD to conduct stratified analyses by urban-rural status. Results The trends in physician distribution worsened after 2004 for all physicians (p valuepediatricians (p value = 0.0057). For all physicians, the trends worsened after 2004 both in predominantly urban prefectures (p value = 0.0012) and others (p valuepediatricians, the distribution worsened in others (p value = 0.0343), but not in predominantly urban prefectures (p value = 0.0584). Conclusion The intra-prefectural distribution of physicians worsened after the launch of the new training program, which may reflect the impact of the new postgraduate program. In pediatrics, changes in the Gini trend differed significantly before and after the launch of the new training program in others, but not in predominantly urban prefectures. Further observation is needed to explore how this difference in trends affects the health status of the child

    Full Text Available Infection and transmission of multidrug-resistant Mycobacterium tuberculosis (MDR-Mtb and extensively drug-resistant M. tuberculosis (XDR-Mtb is a serious health problem. We analyzed a total of 1,110 Mtb isolates in Osaka Prefecture and neighboring areas from April 2000 to March 2009. A total of 89 MDR-Mtb were identified, 36 (48.5% of which were determined to be XDR-Mtb. Among the 89 MDR-Mtb isolates, 24 (27.0% phylogenetically distributed into six clusters based on mycobacterial interspersed repetitive units-various number of tandem repeats (MIRU-VNTR typing. Among these six clusters, the MIRU-VNTR patterns of four (OM-V02, OM-V03, OM-V04, and OM-V06 were only found for MDR-Mtb. Further analysis revealed that all isolates belonging to OM-V02 and OM-V03, and two isolates from OM-V04 were clonal. Importantly such genotypes were not observed for drug-sensitive isolates. These suggest that few but transmissible clones can transmit after acquiring multidrug resistance and colonize even in a country with a developed, well-organized healthcare system.

    Makiko Orita

    Full Text Available As a result of the accident at the Fukushima Daiichi Nuclear Power Plant (FNPP on 11 March 2011, a huge amount of radionuclides, including radiocesium, was released and spread over a wide area of eastern Japan. Although three years have passed since the accident, residents around the FNPP are anxious about internal radiation exposure due to radiocesium. In this study, we screened internal radiation exposure doses in Iwaki city of Fukushima prefecture, using a whole-body counter. The first screening was conducted from October 2012 to February 2013, and the second screening was conducted from May to November 2013. Study participants were employees of ALPINE and their families who underwent examination. A total of 2,839 participants (1,366 men and 1,473 women, 1-86 years old underwent the first screening, and 2,092 (1,022 men and 1,070 women, 1-86 years old underwent the second screening. The results showed that 99% of subjects registered below 300 Bq per body in the first screening, and all subjects registered below 300 Bq per body in the second screening. The committed effective dose ranged from 0.01-0.06 mSv in the first screening and 0.01-0.02 mSv in the second screening. Long-term follow-up studies are needed to avoid unnecessary chronic internal exposure and to reduce anxiety among the residents by communicating radiation health risks.

    As a result of the accident at the Fukushima Daiichi Nuclear Power Plant (FNPP) on 11 March 2011, a huge amount of radionuclides, including radiocesium, was released and spread over a wide area of eastern Japan. Although three years have passed since the accident, residents around the FNPP are anxious about internal radiation exposure due to radiocesium. In this study, we screened internal radiation exposure doses in Iwaki city of Fukushima prefecture, using a whole-body counter. The first screening was conducted from October 2012 to February 2013, and the second screening was conducted from May to November 2013. Study participants were employees of ALPINE and their families who underwent examination. A total of 2,839 participants (1,366 men and 1,473 women, 1-86 years old) underwent the first screening, and 2,092 (1,022 men and 1,070 women, 1-86 years old) underwent the second screening. The results showed that 99% of subjects registered below 300 Bq per body in the first screening, and all subjects registered below 300 Bq per body in the second screening. The committed effective dose ranged from 0.01-0.06 mSv in the first screening and 0.01-0.02 mSv in the second screening. Long-term follow-up studies are needed to avoid unnecessary chronic internal exposure and to reduce anxiety among the residents by communicating radiation health risks.

    Six regional medical associations in Shiga prefecture agreed to cooperate in an investigation of medical care for male gonococcal and chlamydial urethritis. In June 2011, we sent a questionnaire to 372 medical offices in Shiga prefecture, and analyzed replies of respondents. Ten urologists and 175 non-urologists responded to the survey (response rate 49.7%). Among 185 physicians, 52 (10 urologists and 42 nonurologists) have treated male patients with gonococcal and chlamydial urethritis. More than 20% (42/175) of non-urological clinics are involved in the medical management. At initial diagnosis for sexually transmitted male urethritis, all urologists select the nucleic acid amplification method (100%), whereas many non-urologists do not (35%). For the treatment of chlamydial urethritis, non-urologists select levofloxacin (LVFX, 52.8%) rather than azithromycin (AZM, 22.0%), whereas urologists use AZM (78.0%) mostly but do not use LVFX (0%) (p = 0.023). For the treatment of gonococcal urethritis, non-urologists prefer oral new quinolones (53.1%) compared to urologists (25.0%) (p = 0. 74). For cure judgment of gonoccocal and chlamydial urethritis, many non-urologists rely on the improvement of subjective symptoms (50 and 47%), but urologists do not (10 and 0%) (p = 0.022 and 0.026, respectively). As for recognition of the clinical guideline for sexually transmitted disease, most urologists (90%) know it, but few non-urologists (13%) do (p urethritis in Shiga prefecture. It is important to standardize the medical care for sexually transmitted male urethritis by familiarizing non-urological practitioners with the clinical guideline.

    This paper presented a study on maximizing the use of solar energy in the Prefecture of Lasithi on the island of Crete in southern Greece, followed by an investigation of the possible replacement of diesel and heavy fuel oil. While renewable energy sources such as solar, wind and geothermal energy are abundant on the Greek Islands, their use is limited. This presentation emphasized that solar energy could play a key role in meeting Greece's objective of satisfying 8.6 per cent of its electricity needs using renewable sources by 2010. An optimization methodology was applied to the prefecture in order to exploit the island's solar energy and to satisfy part of its energy needs. In 2001, the population of Lasithi was 76,318. From 1997 to 2002, the total energy consumption in Lasithi increased by an average of 6.4 per cent. The technologies that were considered for the exploitation of solar energy were thermal solar systems (solar radiation into water heating); photovoltaics solar systems (solar radiation into electricity); and, inverted absorber solar stills (solar radiation into drinkable water). A mathematical model was developed to optimize each energy scenario. The basis for analysis was the total amount of diesel, heavy fuel oil and electricity consumed in Lasithi from 1997 to 2002 in correlation with the solar exploitation potential in the prefecture. This paper also presented a review of photovoltaic systems (PV modules, batteries, power conditioning, generators, and pumps), solar air heating systems on buildings and solar water heating systems. It was noted that the extent to which the energy demands will be satisfied by the use of these systems will depend on both financial and environmental criteria. It was determined that for heating and domestic use, the energy from solar collectors, photovoltaics, solar stills and concentrators could meet 97.3 per cent of the energy needs for the prefecture. The remaining energy could be supplied by liquid fuels and the

    The concentrations of 222 Rn existing in air have been studied by using a convenient and highly sensitive Pico-rad detector system at Masutomi spa in Yamanashi Prefecture, Japan. The measurements in air were carried out indoors and outdoors during the winter of 2000 and the summers of 1999 and 2005. The concentrations of 222 Rn in spring water in this region were measured by the liquid scintillation method. The concentrations of natural radionuclides contained in soils surrounding spa areas were also examined by means of the γ-ray energy spectrometry technique using a Ge diode detector to investigate the correlation between the radionuclides contents and 222 Rn concentrations in air at each point of interest. The atmospheric 222 Rn concentrations in these areas were high, ranging from 5 Bq/m 3 to 2676 Bq/m 3 . The radon concentration at each hotel was high in the order of the bath room, the dressing room, the lobby, and the outdoor area near the hotel, with averages and standard deviations of the concentration of 441 ± 79 Bq/m 3 , 351 ± 283 Bq/m 3 , 121 ± 5 Bq/m 3 , and 23 ± 1 Bq/m 3 , respectively. The source of 222 Rn in the air in the bath room is more likely to be the spring water than the soil. The spring water plays carries the radon to the atmosphere. Our measurements indicated that the 222 Rn concentration in the air was affected by the 222 Rn concentration in spring water rather than that in soil. (author)

  15. [The family planning work as suggested by analysis of the age at first marriage in Jiaxing Prefecture, Zhejiang Province].

    Yao, C; Zhao, Y

    1984-01-29

    Since 1970 when the big push for family planning began, China advocated late marriages. In general, the age for late marriage for female peasants is 23 years and 25 for males; for urban females and males, it is 25 and 27 years, respectively. In 1981 the New Marriage Law stipulated the age at marriage to be 20 years for females and 22 for males (these ages are lower than the ages advocated for marriage in actual practice). Despite the New Marriage Law, however, there was in 1981 an increase in the number of people who married before attaining the "late marriage age," thereby creating problems in family planning work. Since 1981, early marriages have been an increasing phenomenon (for the purposes of this essay, age at early marriage is 23 years for females and 25 for males). Jiaxing Prefecture had a 460.53% increase from 1979 to 1981 in the number of women who married early. The following findings were based on studies of Tungxiang and Pinghu Countries. Early marriages as well as "regular" marriages have increased greatly, with early marriage exceeding the number of other marriages. Urban marriages are far more moderate in number than rural marriages, partly because family planning work in urban areas is more effective. Early marriage in areas where family planning work was effective is less extreme than in areas where family planning work was ineffective. Findings from Kayuan Commune of Tungxiang County shows that 47.8% of all male marriages in 1981 were early marriages, as opposed to 6.3% in 1980. The average age for men at marriage in 1981 was 1.6 years younger than in 1980, and .75 years younger for females. Undoubtedly the New Marriage Law influenced the trend in early marriages, but the main reason is that the agarian economy is backwards. Further, traditional attitudes (e.g., "the sooner the children come the sooner the riches come") prevail.

  16. Current status and problems of decontamination by municipalities in Fukushima Prefecture. Records from four and a half years after the Fukushima Daiichi Nuclear Power Plant accident

    International Nuclear Information System (INIS)

    This study discusses the current status and problems of decontamination by 52 municipalities out of 59 municipalities in Fukushima Prefecture, four and a half years after the Fukushima Daiichi Nuclear Power Plant accident, mainly based on the results of a questionnaire survey. The area corresponds to in all municipalities except for the 7 whose entire administrative area has been designated as Special Decontamination Area. This study reveals that (1) the number of municipalities which planned, ordered and implemented decontamination work has peaked although decontamination work of public facilities, housing, roads, farmland and forests has been still carried out in many municipalities, (2) about half of the municipalities have not secured enough temporary storage sites for contaminated soil and waste, (3) many municipalities recognize that construction of interim storage facilities, transfer of contaminated soil and waste from each municipality to interim storage facilities, and maintenance of temporary storage sites are major challenges concerning decontamination work, (4) about half of the municipalities regard efforts concerning decontamination work by the national government and the Fukushima prefectural government office as inadequate, (5) not a few municipalities recognize that residents cannot live their lives with a sense of safety and security unless air radiation dose is reduced to the level before the accident, and (6) most municipalities recognize that safe living environments can be recovered by decontamination work. Finally, based on these results, this study points out early completion of interim storage facilities and development of conditions to maintain and manage temporary storage sites, the end of decontamination work based on the air radiation dose rate, and establishment of decontamination policies concerning forests, rivers and waterways, as main future challenges concerning decontamination work by municipalities.

    Summary Background The incidence of femoral neck and trochanteric fractures reportedly differ by age and regionality. We investigated differences in monthly variations of the occurrence of femoral neck and trochanteric fractures as well as place and cause of injury in the Kyoto prefecture over a 6-year period. Methods Fracture type (neck or trochanteric fracture), age, sex, place of injury, and cause of injury were surveyed among patients aged ≥ 65 years with hip fractures that occurred between 2008 and 2013 who were treated in 1 of 13 participating hospitals (5 in an urban area and 8 in a rural area). The proportion of sick beds in the participating hospitals was 24.7% (4,151/16,781). Monthly variations in the number of patients were investigated in urban and rural areas in addition to the entire Kyoto prefecture. Place of injury was classified as indoors or outdoors, and cause of injury was categorized as simple fall, accident, or uncertain. Results There were 2,826 patients with neck fractures (mean age, 82.1 years) and 3,305 patients with trochanteric fractures (mean age, 85.0 years). There were similarities in the monthly variation of the number of fractures in addition to the place and cause of injury between neck and trochanteric fractures. Indoors (approximately 74%) and simple falls (approximately 78%) were the primary place and cause of injury, respectively. The place of injury was not significantly different by fracture type with each age group. Significantly more patients with neck fracture had “uncertain” as the cause of injury than trochanteric fracture in all age groups. Conclusions Based on the results of the present study, the injury pattern might not have a great effect on the susceptibility difference between neck and trochanteric fractures. PMID:27252738

    Kumagai, Shinichiro

    This article overviews the situations of damage and reconstruction of mainly public libraries in Miyagi Prefecture about 9 months after the Great East Japan Earthquake. Serious damage of library buildings was due not only to the tsunami or seismic sea wave but to violent shaking, the latter less reported by the media. We at the Miyagi Prefectural Library implemented reconstruction assistance for regional public libraries in both direct and indirect ways. Among them, we report in detail on the support we offered until the Minami-sanriku Town Library reopened its service. We highlight a prefectural library's role, acting between supporters and those supportees, to consider the necessity of middle organizations. We clarify what challenges we face and examine how best to provide assistance in case of large-scale disasters.

    Full Text Available The aim of this paper is to explain why we have conducted “Traffic Safety Education” in the Kagawa Prefecture during the past ten years so as to clarify the important factors for preventing painful traffic accidents in advance. To meet this aim, we firstly clarify the reason why we eventually decided to conduct “Traffic Safety Education” in the Kagawa Prefecture. In other words, the organization of powerful actors and/or leaders to cope with traffic accidents plays a very important role in “Traffic Safety Education.” Then, we specifically describe the essential parts of our “Traffic Safety Education”. In this respect, we have decided to select the following two aims: to reduce the number of traffic accidents, and to improve traffic manners, respectively. Thirdly, we evaluate various measures, such as teaching materials, teaching methods, and other activities of our “Traffic Safety Education” in detail. Lastly, we summarize the remaining tasks, which have been revealed so far, together with some concluding remarks.

    To 2000 people who were randomly sampled from the basic register of residents in Fukui prefecture, we conducted a questionnaire survey asking their interest in, knowledge of and attitude toward nuclear power, to analyze which perceptions and opinions they had and factors influencing them. The ratios of respondents in Fukui prefecture who think nuclear power is safe, necessary, and should be developed more, are higher than those of surveyed residents who live in other regions where nuclear power plants had been in operation. Differences in gender and age are nearly the same as those found in the nation-wide surveys has shown. The respondents in 'Tsuruga' region, one of the centers of nuclear power research and development, are more acceptive and affirmative to the nuclear power than those in other regions, although they have less knowledge and credibility for nuclear power safety measures, such as regulation and monitoring by government, countermeasure of earthquake, training of workers and so on. We analyzed the perception of risk and the sense of security for nuclear power, and the opinions for necessity and development of nuclear power, using a regression model. According to the estimated 'Tsuruga' model, risk perception of Tsuruga respondents does not affect their opinion if nuclear power should be developed. No influence of the risk perception on their opinion for nuclear power suggest a possibility that residents have strong trust in nuclear power technology and electric power companies based on their long term experience.

    Full Text Available Brucellosis is one of the severe public health problems; the cumulative number of new human brucellosis cases reached 211515 from 2010 to 2014 in China. Bayingolin Mongol Autonomous Prefecture is situated in the southeast of Xinjiang, where brucellosis infection occurs every year. Based on the reported data of newly acute human brucellosis cases for each season in Bayingolin Mongol Autonomous Prefecture, we proposed a susceptible, exposed, infected, and vaccinated (SEIV model with periodic transmission rates to investigate the seasonal brucellosis transmission dynamics among sheep/cattle and from sheep/cattle to humans. Compared with the criteria of MAPE and RMSPE, the model simulations agree to the data on newly acute human brucellosis. We predict that the number of newly acute human brucellosis is increasing and will peak 15325 [95% CI: 11920–18242] around the summer of 2023. We also estimate the basic reproduction number R0=2.5524 [95% CI: 2.5129–2.6225] and perform some sensitivity analysis of the newly acute human brucellosis cases and the basic reproduction number R0 in terms of model parameters. Our study demonstrates that reducing the birth number of sheep/cattle, raising the slaughter rate of infected sheep/cattle, increasing the vaccination rate of susceptible sheep/cattle, and decreasing the loss rate of vaccination are effective strategies to control brucellosis epidemic.

    This study proposes an estimation approach to panel count data, truncated at zero, in order to apply a contingent behavior travel cost method to revealed and stated preference data collected via a web-based survey. We develop zero-truncated panel Poisson mixture models by focusing on respondents who visited a site. In addition, we introduce an inverse Gaussian distribution to unobserved individual heterogeneity as an alternative to a popular gamma distribution, making it possible to capture effectively the long tail typically observed in trip data. We apply the proposed method to estimate the impact on tourism benefits in Fukushima Prefecture as a result of the Fukushima Nuclear Power Plant No. 1 accident. Copyright © 2018 Elsevier Ltd.

    Histamine food poisoning is caused by ingestion of spoiled fish containing high levels of histamine. This paper reports cases in which histamine was detected in Osaka prefecture in fiscal year 2015 in a survey of fish and fishery products on the market and the food poisoning. A suspected case of histamine food poisoning was also evaluated to investigate the cause and minimize further problems. Histamine in food was separated on SPE cartridge columns, and analyzed after derivatization with fluorescamine by means of HPLC-FL. Histamine was detected in some fishery products on the market and in food that had caused poisoning. The samples in which histamine was detected were semi-dried whole round herring (Urumeiwashi-maruboshi), mackerel (Saba) and sardine dumpling (Iwashi-tsumire). These foods were the main causes of histamine food poisoning according to the report of the Ministry of Health, Labour and Welfare, Government of Japan.

    This paper investigated radiocarbon dating of earthenware of the Earliest Jomon period from Obihiro City, in Hokkaido Prefecture. The authors investigated radiocarbon age differences among charred woods and charred residues on the surface of potteries. Results of radiocarbon dates of URAHORO-type pottery adhesions showed ca. 7560-7987 14 C BP, and that of charcoals were ca. 7180 14 C BP and 7285 14 C BP. The age of charred residues on the inside surface of potteries show 300-800 yrs older than the 14 C age of the charred woods, which corresponded to the actual age of the archaeological site, respectively. It becomes a cause to have cooked the salmon by earthenware and I think that the marine reservoir effect occurred. (author)

    The concentration and size distribution of 210 Po in particulate matters in the atmosphere were measured around the active volcano, Mt. Sakurajima in Kagoshima prefecture, Japan. The samples were collected eight times at four sampling points for the period from June 1994 to January 1996. The highest concentration of 210 Po was 2940 μBq/m 3 at Akamizu located 2 km away from the crater of Mt. Sakurajima. The 210 Po concentrations decreased with the increase of distance form Mt. Sakurajima. The size distribution curves of 210 Po in the particulate matters showed that 210 Po is usually condensed to fine particles smaller than 2 μm in diameter. In addition, it was suggested that the 210 Po concentration in particulate matters collected at Akamizu was affected by the wind direction over Mt. Sakurajima. (author)

    The Neogene Tertiary strata, distributed in the central part of Tottori Prefecture, are volcano-stratigraphically classified, as shown in Figure 3. The Miocene strata are divided into Ojika formation and Mitoku formation in ascending order. Ojika formation, composed of plagio-rhyolitic pyroclastics and lavas, abuts against the basement rocks. Furthermore, some breaccias derived from the talus basal conglomerate beds are found in Ojika formation. Mitoku formation abuts both against the basement rocks and Ojika formation, and sometimes overlaps on the basement rocks. From the investigation into the Miocene strata, it is clarified that the depression took place prior to the volcanic activities at the earliest stage of the present Miocene sedimentary basin.

    2012-01-01

    Part of the Gunma Mental Health Center (a mental health welfare center), the Gunma Psychiatric Emergency Information Center (IC) is a de facto compulsory transfer center that centrally handles the compulsory transfer to medical examinations and hospitals of people with psychiatric issues who are detained by the police within Gunma Prefecture and conducts outreach activities for people with various social difficulties. The dichotomy in compulsory transfer is the conflict between the medical benefit to the patient and the demand for safety by the family and local residents. A triage system focusing on both the degree of risk to others and the necessity of treatment was thus implemented by Gunma Prefecture in the late 1990s, with the IC established as a compulsory transfer center. IC outreach activities commenced due to requests from healthcare centers and local authorities. For those patients deemed by the IC as requiring treatment, voluntary psychiatric examination is promoted where possible. However, the potential for and methods of crisis intervention through involuntary treatment via compulsory transfer are also explained to patients, families and local residents. Support for relapse prevention can also be provided following involuntary hospitalization via compulsory transfer. In this way, the IC, which is in charge of compulsory transfer and conducts outreach activities in cooperation with healthcare centers and local authorities, considers the demand for safety by the local community while respecting the medical benefit to the patient. Furthermore, as the IC is an administrative body rather than a hospital, a treatment contract with the patient is not always necessary and involvement can continue even in the face of patient resistance. We present herein the case of a patient who, together with his family, strongly rejected medical and welfare involvement. The changing situation surrounding the patient and family was appropriately handled through continued

    The death investigation system in Japan is in the midst of a great transformation. As part of efforts to revise this system, in this study we analyzed the reasons the police refer unnatural death cases for forensic autopsy and, from an understanding of the trends of such referrals, we discuss the future direction of handling unnatural deaths in our country. For 1618 forensic autopsy cases handled by the First Investigation Division of Chiba Prefectural Police that were referred to our institution for forensic autopsy between 2003 and 2012, we tallied the number of autopsies by sex, age group, and reason for forensic autopsy for each year and investigated trends in the referrals over time. The results revealed that the number of autopsies increased annually from 2003 to 2012, with a marked increase from 2010. The number of autopsies increased particularly for cases of suspected criminal deaths, where it was unclear to the police before the forensic autopsy whether or not the death resulted from a criminal act. Our findings suggest that the number of forensic autopsies will continue to increase into the future in Chiba prefecture, and is a trend that is inevitable if we are to prevent criminal death cases from being overlooked. Although referrals for forensic autopsy in Japan are made only when criminal activity is suspected, the original purpose of death investigations is not only to avoid overlooking crimes, but also to flag public health issues. Therefore, together with the police, we need to review the original purpose and conduct more in-depth discussions about when referrals are necessary. Copyright © 2014 Elsevier Ireland Ltd.

    The damaged Fukushima Daiichi nuclear power station (FDNPS) in Japan following the earthquake in March 2011 led to a massive release of radioactive isotopes into the environment. The atmospheric releases have created a footprint of radioactive contamination in the terrestrial ecosystems around the site, with a hot spot area that extends up to 80-km northwest. Despite some data are available on medium and biota contamination, there is still a lack of knowledge on possible ecological consequences due to the complexity of the exposure situation. Few papers were published using data observed in situ, reporting a reduction of bird and invertebrate abundance (Moeller et al., 2012, 2013) and morphological effects in butterflies (Hiyama et al., 2012). But as for any contaminant, the biological effects are dependent on the dose received, and an accurate dose estimation is needed to be able to correctly predict ecological risk. An early study has published preliminary radiological dose reconstruction from Fukushima wildlife signaling potential ecological consequences, but without using any quantitative data relating to biological samples (Garnier-Laplace et al., 2011). In this general framework, the work presented here aims at refining the first assessment conducted to evaluate possible consequences of the FDNPS radioactive releases, focusing on some bird species, studied in Fukushima but also in Chernobyl. Public data available on bird and soil contamination were used to check the bird contamination model used, showing that radioactive contamination predictions were within the range of variation of measured data. This model was then applied to estimate doses in bird species living in the Fukushima prefecture and known to reproduce during the period just after the nuclear power plant accident, based on ecological maps established for Japan. The influence of life stages and species ecological characteristics was taken into account on the dose estimates. The heterogeneity of

    The organ donation rate in Japan is much lower than that in other developed countries for several reasons. An advanced educational program for in-hospital procurement coordinators is a possible solution for this. We introduced a Transplant Procurement Management (TPM) educational program at Hyogo Prefecture, Japan. Ten healthcare professionals at Hyogo Prefecture participated in the Advanced International TPM course to educate themselves on TPM and held 2 TPM Model Organ Procurement Training Workshops at Hyogo Prefecture for in-hospital procurement coordinators. Furthermore, we held 2 workshops outside Hyogo Prefecture and at the same time undertook a pre-workshop questionnaire survey to evaluate the ability and motivation with respect to organ donation. To evaluate the effectiveness of the workshops, we conducted post-workshop and 3-months-after workshop questionnaire surveys. The results of the pre-workshop survey revealed that in-hospital procurement coordinators lacked the knowledge regarding the entire organ donation process, the current status of organ donation in Japan, and the definition of brain death. Moreover, they did not completely understand the meaning of "organ donation." The results of the post-workshop questionnaire survey showed that the educational program was effective to improve the knowledge and skills of organ donation and motivated behavioral changes among the participants. The survey results showed that our TPM model educational program offered sufficient knowledge and skills to increase organ donation at Hyogo Prefecture. We will continue this program and make an effort to further contribute to the Japanese organ donation activities. Copyright © 2016 Elsevier Inc. All rights reserved.

    On 11 March 2011 a 9.0 earthquake and the resulting tsunami occurred in central-eastern Japan triggering, one day after, the Fukushima Dai-ichi nuclear power plant (DNPP) accident. Despite the bulk of radionuclides (ca. 80%) were transported offshore and out over the Pacific Ocean, significant wet and dry deposits of those radionuclides occurred mainly in the Fukushima Prefecture and in a minor way in the Miyagi, Tochigi, Gunma and Ibaraki Prefectures. As a consequence and among other radionuclides, a total of 511,000 TBq of I-131, 13,500 TBq of Cs-134 and 13,600 TBq of Cs-137 were released into the atmosphere and the ocean, contaminating cultivated soils, rivers, settlements and forested areas. This accident caused severe environmental and economic damages. Several decontamination practices have done, including tree thinning and litter removal within the forests and tree plantations. In this study we analysed the effect of eight different management practices on the radiocesium (Cs-134 and Cs-137) discharge rates during 20 months (May'2013 - Dec'2014) in a Japanese cedar (Cryptomeria japonica) plantation (stand age of 57 years), located in a hillslope near the Kawauchi village, Fukushima Prefecture, northern Japan. This study area (37⁰ 20' 04" N, 140⁰ 53' 13.5" E) is located 16 km southwestern from the DNPP and within the evacuation area. The soils are Andosols. Ten runoff plots (5 x 2 meters) were installed and measurements started on May 2013. Two plots remained without any treatment as control plots and the other eight plots represented the following management practices: Mng1) Litter removal + clear-cutting (no sheet); Mng2) Litter removal + clear-cutting (no sheet); Mng3) Litter removal + clear-cutting (no sheet); Mng4) Litter removal; Mng5) Thinning (logged area); Mng6) Thinning (under remnant trees); Mng7) Litter removal + thinning (logged area); Mng8) Litter removal + thinning (under remnant trees). Each plot had a gauging station and sediment samples

    Objectives In Ibaraki Prefecture, all (nursery) schools have joined the (Nursery) School Absenteeism Surveillance System (hereafter denoted as (N)SASSy), which is operated by the Japan School Health Association to monitor the prevalence of infectious diseases, the early detection and response for outbreaks, and prevention of large outbreaks. Prefectural government officers also utilize it as a control measure for infectious diseases. In particular, when cases of measles or rubella are registered, (N)SASSy sends e-mails automatically to prefectural government officers to activate control measures. This paper summarizes administrative responses by prefectural government officers for measles or rubella cases using (N)SASSy and discusses the future challenges.Methods We summarized registration, detection, and first response data for measles or rubella cases in (N)SASSy and compared the number of detected and reported cases enforced by the Infectious Diseases Control Law from January 1, 2013 to December 31, 2014.Results The public health center questioned hospitals/clinics and (nursery) schools about all registered measles or rubella cases in (N)SASSy on the same day to check the entered information. In the past 2 years, there were 5 measles and 56 rubella cases in 2013 and 1 measles and 19 rubella cases in 2014 registered with (N)SASSy. All cases were checked and investigated by the public health center. Of all cases detected by (N)SASSy, 7 rubella cases in 2013 and 1 rubella case in 2014 were reported based on the law. No measles cases were reported in the 2 years. The results of investigations and laboratory tests were given as feedback to the (nursery) schools. If the case did not case definition determined by the law, we changed the status in (N)SASSy to suspected or discarded cases.Conclusion Since (N)SASSy assists prefectural government officers with earlier detection of and response for infectious diseases, it definitely contributes to infection control

    Large quantities of radionuclides were released from the accident of the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) in March 2011 and farmlands and forests in Fukushima Prefecture were contaminated.The most significant radionuclides related to the contamination of vegetation are {sup 134}Cs (half-life: 2 y) and {sup 137}Cs (half-life: 30 y).Concentrations of radiocesium in vegetables and rice decreased over time to values markedly lower than the guideline (100 Bq/kg). However, radiocesium concentrations in some edible wild plants and mushrooms have still shown very high level. Therefore, it is important to identify plants which accumulate cesium and to clarify the transfer mechanism of radiocesium. In this study, we analyzed both radiocesium and stable cesium in edible wild plants (Sansai) collected from forests in Fukushima Prefecture. Possible mechanisms of high radiocesium transfer into the plants in forest ecosystems were considered. Wild plants were collected from forests in Iitate-mura, Fukushima Prefecture, in 2012 and 2013. We have focused on Koshiabura (Acanthopanaxsciadophylloides) a plant related to Araliaceae and collected their leaves from four different trees in May and July 2013.Radiocesium ({sup 134}Cs and {sup 137}Cs) concentrations were measured with a Ge-detector. For elemental analysis, the samples were freeze-dried and milled with a mixer. Powdered samples (0.1 g) were digested in teflon vessels with an acid mixture (HNO{sub 3}, HF and HClO{sub 4}) on a hot plate. After digestion, each sample was evaporated to dryness. Then, the sample residue was dissolved in 2% HNO{sub 3}. The concentrations of major and minor elements were determined by ICP-MS. Leaves of Koshiabura showed very high radiocesium concentrations up to 60,000 Bq/kg on a dry weight basis, or 10,000 Bq/kg on a wet weight basis.Root uptake and translocation of radiocesium from other parts of the plants to the leaves were expected to occur. Koshiabura plants tend to be shallowly

    Background To investigate the differences in the characteristics of femoral neck and trochanteric fractures between urban and rural areas of Kyoto Prefecture in Japan. Methods Fracture type (neck vs. trochanteric), age, sex, place where fracture occurred (indoors vs. outdoors), and cause of injury were surveyed among patients aged ≥65 years who sustained hip fractures between 2008 and 2010 and who were treated at 1 of 13 participating hospitals (5 urban, 8 rural). The ratio of sick beds to total number of beds at the participating hospitals was 19.6% (2,188/11,158) in the urban area and 34.9% (1,963/5,623) in the rural area. We also investigated the incidence of hip fracture in Tango medical district as a representative rural area. Results There were 1,346 neck (mean age, 82.4 years) and 1,606 trochanteric fractures (mean age, 85.0 years). The ratio of neck to trochanteric fractures was higher in the urban area than in the rural area in all age groups (65–74, 75–84, and ≥ 85 years). There were no apparent differences in place or cause of injury. The incidence of hip fracture in the women of Tango medical district was lower than the national average. Conclusions There was a difference in the ratio of neck to trochanteric fractures between urban and rural areas. This difference is estimated to be caused by the high and low incidence of neck fracture in urban and rural areas, respectively. PMID:24156244

    There is currently no large population data-based data set in Kashgar Prefecture Uyghur. The allele frequencies of 18 autosomal short tandem repeat (STR) loci included in the DNATyper™ 19 kit were evaluated in 2600 Uyghur individuals living in Kashgar Prefecture, Northwest China. The values of combined power of discrimination (CPD) and combined probability of exclusion (CPE) of all 18 autosomal STR loci were 0.99999999999999999998235 and 0.99999998670, respectively. Phylogenetic analyses revealed that the Uyghur population has a closer relationship with the Xinjiang-Kazakh, Inner Mongolia-Mongolian, and other three Uyghur populations. In addition, our results are consistent with the hypothesis that Uyghur population is an admixture of Eastern Asian and European populations.

    Full Text Available Given the shrinking proportion of agriculture output and the growing mobility of the labor force in China, how agricultural labor productivity develops has become an increasingly attractive topic for researchers and policy makers. This study aims to depict the development trajectory of agricultural labor productivity in China after its WTO entry. Based on a balanced panel data containing 287 Chinese prefectures from 2000 to 2013, this study applies the Latent Growth Curve Model (LGCM and finds that the agricultural labor productivity follows a piecewise growth path with two breaking points in the years of 2004 and 2009. This may stem from some exogenous stimulus, such as supporting policies launched in the breaking years. Further statistical analysis shows an expanding gap of agricultural labor productivity among different Chinese prefectures.

    To investigate the natural hosts infected with Paragonimus sp. and identify the species of the parasite in selected counties/districts of Jinhua prefecture in Zhejiang Province. Three townships/towns were randomly sampled from each of the 9 counties/districts in Jinhua as pilot spots for the survey. Fresh-water snails were collected from the fields for examining cercariae. Crabs were collected and detected for metacercariae by routine technique and the metacercariae were fed to dogs purchased in areas free from paragonimiasis. Fecal materials of dogs and cats around the villages and streams where crabs were found infected were collected for examining eggs. The artificially infected dogs were sacrificed 55 d after infection to receive adult worms. The size of cercariae, metacercariae, eggs and adult worms was measured. After the DNA of the adult worm was extracted, PCR was used to amplify the COI gene and ITS2 gene of the mitochondria from the worms. Homology with relative strains/isolates was analyzed and phylogenetic tree constructed. The survey demonstrated that the snail Semisulcospira libertina and the crab Sinopotamon chekiangense served as the first and second intermediate hosts respectively. Natural infection was found in Wucheng District with an infection rate of 0.2% (2/1,088) in snails and 76.7% (46/60) in crabs in Shafan township, and an infection index (II) of 2.0 in crabs, 0.1% (1/1,683) in snails and 53.0% (46/60) in crabs with an II of 0.9 in Langya town. The infection rate was 0 (0/575) in snails and 30.0% (18/60) in crabs with an II of 0.1 in Baimu township of Wuyi County. Paragonimus eggs were detected in feces of stray cats with a positive rate of 8.3% (1/12) in Shafan and 0.6% (1/17) in Langya. The size and morphology of the cercariae, metacercariae, eggs and adult worms were similar to those of Paragonimus westermani. The sequences of the COI and ITS2 genes were with 390 bp and 363 bp respectively, indicating a homology of 88.2%-98.2% and 86

    Enterobacteriaceae producing extended spectrum β-lactamase (ESBL) are distributed worldwide. In this study, 114 ESBL-producing Enterobacteriaceae were isolated by analyzing 1672 clinical isolates of Enterobacteriaceae collected from an Okinawa prefectural hospital in Japan between June 2013 and July 2014. The overall prevalence of ESBL-producing Enterobacteriaceae was 6.8%; the prevalence of different bacterial species among the ESBL-producing isolates was as follows: 11.5% Escherichia coli (90 of 783 isolates), 6.2% Klebsiella pneumoniae (19 of 307 isolates), and 11.1% Proteus mirabilis (5 of 45 isolates). The ESBL types blaCTX-M-1, -3, -15, -2, -14, -27, and mutants of blaSHV-1 were detected. Among them, blaCTX-M-15 (33.3%), blaCTX-M-14 (27.8%) and blaCTX-M-27 (33.3%) were dominant in the E. coli isolates, whereas a blaSHV mutant which possessed four mutations (Tyr7Phe, Leu35Gln, Gly238Ser and Glu240Lys) in the amino acid sequence of SHV-1 dominated in the K. pneumoniae isolates (11 of 19, 57.9%). The pandemic E. coli ST131 clone was found to constitute 3.3% of the overall examined isolates and 62.2% of the ESBL-producing E. coli isolates. Our results suggest that the genetic combination of blaCTX-M, and blaSHV and antibiotics-resistant profile were different from that in other regions such as other areas of Japan, Asia, Europe, and North America, especially in the ESBL-producing K. pneumoniae isolates and in the E. coli B2-O25b-ST131 isolates possessing blaCTX-M-15 (40.7% of the E. coli B2-O25b-ST131 isolates). Taken together, our results indicate that the ESBL-producing Enterobacteriaceae in Okinawa, Japan, might be of a unique nature.

    In a comparative analysis of mortality among atomic bomb survivors versus the non-exposed, both resident in Hiroshima Prefecture, it was found that in addition to leukaemia, malignant lymphoma, multiple myeloma, and cancers of the thyroid gland, breast, lung, esophagus, stomach, urinary organs and salivary gland which have been reported from the past to be elevated in risk among atomic bomb survivors, cancers of the colon, larynx, accessory sinuses, uterus, ovary and testis, diseases of the blood, cirrhosis of liver, hypertensive disease and diabetes mellitus were elevated in risk, but the risk of cerebrovascular disease, heart disease, peptic ulcer, gastroenteritis, senility, and accidents was lower than the non-exposed. The relationship of atomic bomb exposure to the relative risk of cancers of the lung, breast, uterus, and testis could be readily explained, but the relationship between atomic bomb exposure and the relative risk of cancers of many other sites, diseases of the blood, and other causes of death was inconsistent. One of the reasons why the risk of senility was low and the risk of diseases of the blood, malignant neoplasms, diabetes mellitus, and hypertensive disease was high is considered to be the higher diagnostic accuracy in atomic bomb survivors.

    An epidemiological study on radiation induced tumor was carried out in the Ohita Prefectural Hospital in 1989. Radiation induced tumors were chosen among 62,831 surgical or biopsy specimens examined since 1968 to 1988. These tumors were defined as following conditions such as having a history of radiation therapy, occurring in the same field of irradiation, and having a latent period over five years. Total of eleven malignant tumors were selected with the average age of 64.2 years old, and the average latency of 16.4 years. All of them were female and seven cases belonged to A-1 group according to the reliability classification. The first tumor was all malignant and consisted of 9 uterus cancers and one rectal cancer. The second tumor included three rectal cancers, three vaginal cancers, two ureto-bladder cancers, one uterine body cancer, and one lymphangiosarcoma. Histological study showed poorly differentiated adenocarcinoma in two rectal cancers in which this type was unusual as rectal cancer. Others were common histological types identical to the location. Delayed effects of irradiation was confirmed in a background of some tumors. For instance, marked fibrosis, atypical fibroblast, and thickening of blood vessel were nominated. Total amount of irradiation ranged form 24 to 92 grey, and the year of irradiation concentrated in 1969 to 1973 (75%) and the year of discovery concentrated in 1983 to 1988 (75%). This study suggested the necessity of further investigation in other medical institutions and accumulation of the tumors. (author)

    Full Text Available The aim of this research was the isolation of Legionella spp. from domestic water supply networks in the Prefecture of Arta. A total of 100 water samples, from 25 houses, were collected. Half of the samples concerned the cold water and half the hot water supply. Purpose was to detect colonization of the water networks with Legionella spp. >500 cfu/L by using the method of filtration (ISO 11731. Out of 100 samples, 6 samples from 3 houses were positive for Legionella spp. Legionella pneumophila serogroup 2–14 was isolated in 5 of 6 samples, whereas in the sixth sample Legionella anisa was identified. Only three of the samples had residual chloride over 0.2 mg/L, rate which is necessary for potable water, according to the Greek hygienic practice. Concerning the temperature of hot water, the mean temperature of the negative for Legionella samples was higher compared to the mean temperature of the positive for Legionella samples (49.9°C versus 45.5°C. It is estimated that there is risk of infection through the use of showers. The low concentration of chloride and the temperature, which was found within the limits favorable to developing Legionella spp. (20–45°C, provide fertile ground for proliferation of the bacteria.

    Radioactivity from the Fukushima Daiichi Nuclear Power Plant (F-1NPP) accident in deposition samples has been monitored at the National Institute of Radiological Sciences (NIRS) in Chiba Prefecture, Japan, located about 220 km south-southwest of the F-1NPP. Sampling was carried out from 15 March 2011, two to three times a day for 10 d and then once a day until 22 April 2011. Gamma-ray spectrometry of fallout deposition samples revealed the presence of (131)I, (132)I, (132)Te, (134)Cs, and (137)Cs. The largest deposition was observed during 7:00-16:00 on 21 March. The estimated total deposition densities at NIRS were 1.40 × 10(5) Bq m(-2) for (131)I, 4.12 × 10(4) Bq m(-2) for (132)Te, 1.45 × 10(4) Bq m(-2) for (134)Cs, and 1.48 × 10(4) Bq m(-2) for (137)Cs (corrected to 11 March 2011). The obtained densities of (134)Cs and (137)Cs were also supported by the accumulated amount of (134)Cs and (137)Cs in soil near the deposition sampling site. For the vertical profile of those radionuclides in soil at NIRS, about 94% of the total deposition was distributed in the top 10 mm depth on 26 April 2011.

    I studied two genetic diseases, retinitis pigmentosa (RP) and color vision anomaly, in Kamigoto, one of the off-shore islands in Nagasaki Prefecture. The Prevalance of RP patients in this island was estimated to be one in 473 persons. Among the RP patients observed, familial cases whose disorders are transmitted through successive generations comprised 25.7%. Although it seems that the inheritance mode of RP in these familial cases is autosomal dominant, an autosomal recessive fashion showing quasi-dominance cannot be ruled out, because inbreeding frequently occurs on this island. There were at least two types of RP, one with late onset (40 years of age or later) and the other with early onset, and patients with the latter RP tended to have a poor prognosis. Only a few RP patients had posterior subcapsular cataract, and none had pseudexfoliation in spite of advanced age. Color vision anomalies were found in 3.86% of high-school boys and in 0.41% of girls in this island, and they included protanopia (4.2%), protanomaly (10.4%), deuteranopia (37.5%), and deuteranomaly (47.9%). The prevalence in boys was comparable to that in the general Japanese population, but the prevalence in girls was higher in Kamigoto than in other districts. It is most likely that the unique findings regarding the two disorders reflect geographical and/or social features in Kamigoto island.

    A high prevalence of nuclear polyhedrosis has been observed in larval outbreaks of Lymantria mathura in Iwate Prefecture, Japan. However, the virus responsible has not been identified. Here the virus was designated Lymantria mathura nucleopolyhedrovirus (LymaNPV), based on partial sequence results of the lef-8, lef-9, and polh genes and transmission electron microscopic observations. Diagnosis by polymerase chain reaction targeting of the partial polh gene and a subsequent restriction fragment length polymorphism (RFLP) analysis indicated that LymaNPV was an exclusive causative agent for the nuclear polyhedrosis of the L. mathura larvae. LymaNPV was also detected from a very small fraction of L. dispar larvae that co-occurred with L. mathura larvae where the prevalence of LymaNPV-caused disease was high. A bioassay using LymaNPV against L. dispar larvae produced infection with the inoculated virus. This finding was consistent with the results of the field sample analysis. LymaNPV contained six genome types in the L. mathura populations sampled, as determined by RFLP of LymaNPV genomic DNA and southern blot hybridization analyses. None of the genome types was unique to any sampling site, indicating that some flow had occurred among sites. However, genome-type composition seemed to differ among sites. This study provides basic information about the interaction between L. mathura and LymaNPV. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available This study explored the rural revitalizing strategy in FAO's Globally Important Agricultural Heritage System (GIAHS site in Noto Peninsula, Ishikawa Prefecture of Japan, using a case study of edible wild plants. This study assessed the current and possible future utilization of edible wild plants as one important NTFP by clarifying the attitudes of consumers and exploring the challenges of harvesting edible wild plants. Traditional ecological knowledge associated with edible wild plants and the related attitudes of consumers towards wild plants was documented. A questionnaire survey found that a majority of the respondents held positive attitude towards edible wild plants as being healthy, safe food, part of traditional dietary culture. Increasing demand of edible wild plants from urban residents aroused conflicts with local residents’ interest given that around 86% of the forested hills are private in Noto Region. Non timber forest products (NTFP extraction can be seen as a tool for creating socioeconomic relationships that are dependent on healthy, biodiverse ecosystems. It was suggested that Japanese Agricultural Cooperatives (JA and Forestry Cooperatives (FCA could be involved with GIAHS process. As important traditional dietary and ecological system, edible wild plants should be a part of GIAHS project for rural revitalization.

    Measurement and decontamination of surface of trees and surrounding wooden structures contaminated by radioactive substance were studied in the gardens and public parks of Northern Fukushima Prefecture which experienced radioactive contamination due to the accident at the TEPCO's Fukushima Daiichi Nuclear Power Plant. The counts per minute (CPM) above the centre surface of wooden garden tables in open air were 1.5 times higher than those of garden benches and 9 times higher than that of a garden bench in the square gazebo. Decontamination of wooden garden benches by high-pressure washing was more effective than planing. The counts per minute (CPM) above the soil around garden trees increased by 1.2 times after high-pressure washing. Radioactivity counting rate did not decrease when the leaves fallen from zelocova trees were removed; however, they decreased by about half when soil cover was installed at the base of the trees. Clearly, the upper surfaces of garden trees and wooden surrounding structures were strongly contaminated by radioactive substances, and they should be decontaminated by high-pressure washing before removing the surface soil.

    To determine the annual incidence of visual impairment in a Japanese population during a 10-year period. We examined the physical disability certificates issued yearly between 2004 and 2013 in Mie prefecture, Japan. During this period 2468 visually impaired people were registered under the newly defined Act on Welfare of the Physically Disabled Persons' criteria. The age, sex distribution, and causes of visual impairment were determined from the certificates. The major causes of visual impairment during the ten-year period were glaucoma (23.3%), diabetic retinopathy (17.3%), retinitis pigmentosa (12.2%), macular degeneration (9.0%), chorioretinal degeneration or high myopia (7.4%), optic atrophy (5.8%), stroke or brain tumor (5.4%) and cataracts (3.7%). The incidence of glaucoma was significantly higher throughout the period (2004-2013), and that of diabetic retinopathy was lower between 2007 and 2013. The incidence of retinitis pigmentosa did not change significantly during the 10-year period. The incidence of macular degeneration tended to increase between 2004 and 2007, but it decreased significantly between 2007 and 2013. The results indicate that in Japan, the rates of the major causes of visual impairment altered in the most recent 10-year period reflecting the recent changes in the social background and advances in ocular and systemic treatment.

    The Fukushima Health Management Survey (including the Basic Survey for external dose estimation and four detailed surveys) was launched after the Fukushima Dai-ichi Nuclear Power Plant accident. The Basic Survey consists of a questionnaire that asks Fukushima Prefecture residents about their behavior in the first four months after the accident; and responses to the questionnaire have been returned from many residents. The individual external doses are estimated by using digitized behavior data and a computer program that included daily gamma ray dose rate maps drawn after the accident. The individual external doses of 421,394 residents for the first four months (excluding radiation workers) had a distribution as follows: 62.0%, <1 mSv; 94.0%, <2 mSv; 99.4%, <3 mSv. The arithmetic mean and maximum for the individual external doses were 0.8 and 25 mSv, respectively. While most dose estimation studies were based on typical scenarios of evacuation and time spent inside/outside, the Basic Survey estimated doses considering individually different personal behaviors. Thus, doses for some individuals who did not follow typical scenarios could be revealed. Even considering such extreme cases, the estimated external doses were generally low and no discernible increased incidence of radiation-related health effects is expected. PMID:26239643

    Past atmospheric nuclear testing which have been conducted frequently, have caused environmental pollution due to the diffusion of radioactive substances into the atmosphere and from the radioactive fallout. The environmental pollution from nuclear testing into the atmosphere has resulted in the radioactive contamination in agricultural products and has continued for a long time. The radioactive contamination of agricultural products occurs through air, water and soil which were contaminated by radioactive fallout. In this paper, for the purpose of analyzing the extent of the radioactive contamination levels in the agricultural products of Saitama Prefecture, spinach, green soybeans, dried shiitake and welsh onion, were selected among products, as the amount of the harvest is abundant in all of Japan. Radioactivity concentration was investigated by gamma-ray spectrometry and radiochemical analysis. The radioactivity concentrations of artificial radioactive nuclides, cesium-137 ( 137 Cs) and strontium-90 ( 90 Sr), were detected in the range which is considered to be the result of radioactive fallout. Moreover, in order to examine the effect on radioactivity concentrations in agricultural products by culinary processing, the raw agricultural products were boiled, and their radioactivity concentrations were compared with the raw produce. The radioactivity concentrations in the boiled were lower than those in the raw produce. (author)

    A one year survey of indoor radon and thoron concentrations was carried out in offices and dwellings of the Gunma prefecture, Japan. A passive integrating radon and thoron discriminative monitor was used in the survey. The annual mean radon concentration was 22±14 Bq x m -3 , and ranged from 12 to 93 Bq x m -3 among the 56 surveyed rooms. Radon concentration in offices was generally higher than that in the dwellings, with the arithmetic averages of 29 and 17 Bq x m -3 , respectively. Radon concentrations were generally lower in the traditional Japanese wooden houses than those houses built with other building materials. Seasonal variation of indoor radon was also observed in this survey. Compared to summer and autumn, radon concentrations were generally higher in spring and winter. The mean value of thoron to radon ratio was estimated to be 1.3, higher values were observed in the dwellings than in the offices. The annual effective dose from the exposure to indoor radon was estimated to be 0.47 mSv after taking the occupancy factors of offices and dwellings into account. (author)

    Many administrative agencies in Japan are encouraging installation of household rainwater-storage tanks for more effective use of natural rainwater. Water samples were collected periodically from 43 rainwater tanks from 40 households and tested for the presence of Legionella species and the extent of heterotrophic bacteria in Azumino city, Nagano prefecture, Japan. PCR assays indicated the presence of Legionella spp. in 12 (30%) of the 43 tank water samples. Attempts were made to identify correlations between PCR positive samples, topography, pH, chemical oxygen demand (COD), atmospheric temperature and the numbers of heterotrophic bacteria. Between June and October, 2012, the numbers of heterotrophic bacteria in rainwater tanks and the values of COD positively correlated with the presence of Legionella species. In most of the Legionella-positive cases, heterotrophic bacterial cell counts were >10(4) CFU/mL. Moreover, Legionella species were less frequently detected when the COD value was >5 mg KMnO(4)/L. Therefore, at least in Azumino, Japan between June and October 2012, both heterotrophic bacterial counts and COD values may be considered index parameters for the presence of Legionella cells in rainwater tanks. Much more accumulation of such data is needed to verify the accuracy of these findings. © 2013 The Societies and Wiley Publishing Asia Pty Ltd.

    The Nuclear Safety Commission received the report on the results of examination from the ad hoc examination committee. There was no particular effect to atomic energy facilities in the Southern Hyogo Prefecture Earthquake, however, from the viewpoint of perfecting the safety confirmation for atomic energy facilities, the Nuclear Safety Commission set up the aseismatic safety examination committee to investigate the validity of the guidelines related to aseismatic design used for safety examination. The basic plan of the investigation, the outline of the guidelines related to aseismatic design, the state of Southern Hyogo Prefecture Earthquake and the obtained knowledge and the investigation of the validity of the guidelines related to aseismatic design based on the state of Southern Hyogo Prefecture Earthquake are reported. The extraction of the items to be investigated, the evaluation of earthquakes and earthquake motion, vertical earthquake force and active faults, and the way of thinking on right under type earthquakes in the guideline for aseismatic design examination are reported. It was confirmed that the validity of guidelines is not impaired by the earthquake. (K.I.)

    This study aimed to explore the factors associated with information-seeking behaviors regarding medical institutions with Spanish language support among South American Spanish-speaking migrants living in Aichi Prefecture, Japan. The survey targeted South American Spanish-speaking migrants aged 18 years and older currently residing in Aichi Prefecture who had lived in Japan for at least three months and who had previously seen a doctor in Japan. The questionnaire was written in Spanish and the survey was conducted from April to July, 2010. Wilson's information behavior model was used to study information-seeking behavior regarding medical institutions with Spanish language support among 245 respondents who completed the questionnaires (response rate: 58.9%). Experience seeking medical institutions with Spanish language support in the Tokai area was set as the dependent variable and a chi-square test was conducted to examine relationships with language support needs, recognition of and access to medical institutions with Spanish language support, living situation in Japan, and Japanese language skills. Among the 245 respondents, 106 were male (43.3%) and 139 were female (56.7%). The average age was 39.6±11.2 years old and 84.5% were Peruvian. The average length of residency in Japan was 11.0±5.7 years, and 34.3% of respondents had lived in Aichi for 5-9 years. A total of 165 respondents (67.3%) had searched for medical institutions with Spanish language support, while 80 (32.7%) had not. Information-seeking behavior regarding medical institutions with Spanish language support was associated with having previously experienced a need for Spanish language support when seeing doctors in Japan, finding and attending medical institutions with Spanish language support in the Tokai area, length of residency in Japan, Japanese language skills, and the language used in daily life. Experience in requiring Spanish support when sick or injured in Japan motivated respondents to

    Host fish of each mussel was examined in a biotope pond, a drainage canal and fishway between them in Gifu Prefecture from May to October 2008. The main host fish was Zacco platypus in Unio douglasiae and Lanceolaria grayana, Nipponocypris sieboldii in Anodonta sp. and Pronodularia japonensis. In the fish caught at fishway, intensity and total number of glochidium were more the descending fish from the biotope pond than the ascending one from the drainage canal, which suggests that the biotope pond is now the base of supply of juveniles to the neighboring areas.

    1971-01-01

    In the Hokuriku district including Toyama, Ishikawa, and Fukui Prefectures, hot springs of more than 25/sup 0/C were investigated. In the Toyama Prefecture, there are 14 hot springs which are located in an area from the Kurobe River to the Tateyama volcano and in the mountainous area in the southwest. In Ishikawa Prefecture there are 16 hot springs scattered in Hakusan and its vicinity, the Kaga mountains, and in the Noto peninsula. In northern Fukui Prefecture there are seven hot springs. The hot springs in Shirakawa in Gifu Prefecture are characterized as acid springs producing exhalations and H/sub 2/S. These are attributed to the Quaternary volcanoes. The hot springs of Wakura, Katayamazu, and Awara in Ishikawa Prefecture are characterized by a high Cl content which is related to Tertiary andesite. The hot springs of Daishoji, Yamanaka, Yamashiro, Kuritsu, Tatsunokuchi, Yuwaku, and Yunotani are characterized by a low HCO/sub 3/ content. The Ca and SO/sub 4/ content decreases from east to west, and the Na and Cl content increases from west to east. These fluctuations are related to the Tertiary tuff and rhyolite. The hot springs of Kuronagi, Kinshu, and Babadani, located along the Kurobe River are characterized by low levels of dissolved components and high CO/sub 2/ and HCO/sub 3/ content. These trends are related to late Paleozoic granite. Hot springs resources are considered to be connected to geothermal resources. Ten tables, graphs, and maps are provided.

    Nagareyama city is located in the northwestern part of Chiba prefecture in the metropolitan area of Tokyo, Japan. The city is located ∼200 km south of the TEPCO Fukushima Dai-ichi nuclear power plant. As of April 1, 2012, the population of the city was 166,493 and its area was 35.28 km 2 . Responding to many requests from the citizens, the local government has performed official surveys of environmental radiation status after the disaster. The radiation surveillance in this area has been conducted by the radiation protection specialists. The two primary measured quantities were (1) the ambient radiation dose (microsieverts per hour) at all school yards, public parks and at representative locations as selected by the local government, and (2) the specific radioactivity (becquerels per kilogram) of the drinking water and of local food items. These data have been reported on the city's website, in addition to being reported three times per month in the public relations magazine of the local government. This presentation provides the background status and technical information on the related activities. In addition, this presentation documents the measured environmental radiation data. The ambient radiation dose in the city has been surveyed since June of 2011. In the 1st period of the surveillance (from May to September of 2011), data were collected from 40 locations. The highest value of the measured ambient radiation dose was 0.58 μSv h -1 , obtained at the elevation of 1 m above the ground, and the lowest value was 0.17 μSv h -1 . The average level of ambient radiation was ∼0.32 μSv h -1 , and those measured values included the natural background dose rate that was detected by the energy compensation type surveymeters. In the latest period of surveillance, the ambient radiation levels were measured around school yards. The peak value of ambient radiation level was 0.36 μSv h -1 , the minimal value was 0.08 μSv h -1 , and the average over all locations

The local government has officially surveyed the environmental radiation status after the disaster in response to numerous requests from its citizens. The radiation surveillance in this area has been conducted by the radiation protection specialists. The two main goals of the surveillance are (1) to measure the ambient radiation dose (microsieverts per hour) at all the school yards, public parks, and representative measuring points selected by the local government, and (2) to measure the specific radioactivity (becquerels per kilogram) of drinking water and local food items. These data have been reported on the city website as well as in a bi-monthly report in the public relations magazine of the local government. This report presents the background status and technical information on the related activities, and the measured environmental radiation data. The ambient radiation dose in the city has been surveyed since June, 2011. In the 1st period of the surveillance (from May to August, 2011) at a total of 210 survey points, the highest value of the ambient radiation dose was 0.65 μSv h -1 at the height of 1 m from the ground, the lowest was 0.08 μSv h -1 , and the average was 0.25 μSv h -1 . These values include the natural background dose rate detected by the survey meters. In the 4th period, the latest data around school yards were 0.30 at maximum, 0.04 at minimum, and 0.12 μSv h -1 on average. The ambient dose at 41 of 61 school yards and 47 of 635 parks has been reduced under the decontamination project by the local government, so far. The net dose reduction rate, without the natural background dose, was from 30%-80% in the school yards and the parks. Decontamination activity

In the 1st period of the surveillance (from May to August, 2011) at a total of 210 survey points, the highest value of the ambient radiation dose was 0.65 μSv h -1 at the height of 1 m from the ground, the lowest was 0.08 μSv h -1 , and the average was 0.25 μSv h -1 . These values include the natural background dose rate detected by the survey-meters. In the 4th period, the latest data around school yards were 0.30 at maximum, 0.04 at minimum, and 0.12 μSv h -1 on average. The ambient dose at 41 of 61 school yards and 47 of 635 parks has been reduced under the decontamination project by the local government, so far. The net dose reduction rate, without the natural background dose, was from 30%-80% in the school yards and the parks. Decontamination activity

    In Japan, public health nurses (PHNs) play important roles in managing the health of local residents, especially after a disaster. In this study, we assessed radiation anxiety and the stress processing capacity of PHNs in the Fukushima Prefecture in Japan, after the accident at the Fukushima Daiichi Nuclear Power Station (FDNPS). We conducted a questionnaire survey among the PHNs (n=430) in July of 2015 via postal mail. The questions included demographic factors (sex, age and employment position), knowledge about radiation, degree of anxiety about radiation at the time of the FDNPS accident (and at present), by asking them to answer questions about radiation and the Sense of Coherence-13 (SOC-13). We classified the low and high levels of anxiety by asking them to answer questions about radiation, and compared the anxiety-negative (-) group with the anxiety-positive (+) group. Of the PHNs, 269 (62.6%) were classified in the anxiety (-) group and 161 (37.4%) were in the anxiety (+) group. When the multivariate logistic regression analysis was conducted, the PHNs at the time of the accident (OR: 2.37, p=0.007), current general anxieties about radiation (OR: 3.56, pradiation (OR: 2.11, p=0.006) and knowledge of the childhood thyroid cancer increase after the Chernobyl accident (OR: 1.69, p=0.035) were significantly associated with anxiety after the FDNPS accident. The mean SOC-13 was 43.0±7.7, with no significant difference between the anxiety (-) group and anxiety (+) group (p=0.47). Our study suggested that anxiety about radiation was associated with materials and knowledge about radiation in the PHNs in the Fukushima Prefecture 4 years after the FDNPS accident. It is important for PHNs to obtain knowledge and teaching materials about radiation, and radiation education programmes for PHNs must be established in areas that have nuclear facilities.

    The uptake of radiocesium to plants from the soil is affected by many environmental factors, and it is difficult to determine the contribution of uptake among these factors. In addition, these environmental factors should be investigated independently for each field. The aim of this study was to develop a practical and simple method for the estimate of uptake of radiocesium from soil to plants. Rice seedlings were used to estimate the root uptake of radiocesium from seven different soils. To confirm that the seedlings were the effective indicator, the concentration of 137 Cs in the seedlings was compared with that in brown rice and sunflower. The seedlings were cultivated for a week from germination in a phytotron and the concentrations of 137 Cs in the seedlings above ground were determined. To obtain brown rice and sunflower, rice and sunflower were cultivated either in a pot (1/5000 a Wagner pot, 4000 cm 3 ) placed in a glasshouse or in a paddy field in Fukushima prefecture for two to four months. The concentration of 137 Cs in the rice seedlings ranged from 150 to 1900 Bq kg -1 , and that in brown rice and sunflower ranged from 2 to 880 Bq kg -1 and from 580 to 3900 Bq kg -1 , respectively. The Spearman's rank correlation coefficient between the measured concentration of 137 Cs in rice seedlings and the measured concentration of 137 Cs in brown rice and sunflower was 1.0 (p < 0.001 and p = 0.09, respectively). This suggests that the use of rice seedlings in this experiment over a period of two weeks provides an effective indicator for the uptake of 137 Cs from soil to plants over a longer period of time.

    The genus Aeromonas is known to causes diseases such as food poisoning, sepsis, and wound infection. However, the mode of Aeromonas transmission from environment to humans is not clearly understood. To evaluate the health risks of Aeromonas spp. in environmental freshwater, the number, proportion and putative virulence factors of Aeromonas species were investigated in Okinawa Prefecture, Japan. Environmental freshwater samples were collected from three dams, two springs and three private wells. Aeromonas strains were identified by the biochemical method and the viable count was calculated. The production of extracellular enzymes and the virulence genes were investigated for possessing putative virulence factors using representative isolates. At least seven species of already-known Aeromonas isolates as well as unidentified Aeromonas spp. with/without arginin dehydrolase (ADH) exist in water at these sites. Aeromonas spp. was found to exist at over 1000 CFU/100 ml in one spring and two wells. A. veronii biovar sobria and A. jandaei were the predominant species in dams, and A. hydrophila and/or A. eucrenophila were predominant in wells. Almost all the sampled Aeromonas species produced protease, gelatinase, lipase, esterase and DNase, but A. caviae, A. caviae-like bacteria, and A. eucrenophila had low hemolytic activity. Most sampled A. hydrophila strains possessed both aerolysin gene (aer) and hemolysin gene (hlyA), but A. caviae and A. eucrenophila strains did not possess either gene. Since these results indicated that several Aeromonas species having potential pathogenicity exist in environmental water in Okinawa, surveys are recommended as a public health measure.

    The consumption of marine foods such as fish, cephalopod, crustacea, shellfish, algae and processed was surveyed on three kinds of families in Kuji town and Tokai village. The average daily intake through a year was 224 g/d/p for fisherman's families in Kuji, 131 g/d/p for native's families in Tokai and 89 g/d/p for immigrant's families from city to Tokai village, respectively. Fish accounted for about one-half of whole consumption of marine foods. Fisherman's families showed the highest consumption of all kinds of marine foods except algae through a year. Algae was consumed much by the natives in Tokai. (auth.)

    The Fukushima-Daiichi Nuclear Power Plant (F1NPP) accident is an IAEA level 7 event, the same as that of Chernobyl, while the amount of radionuclides released is not comparable. Radioactivity attributed to the F1NPP accident was detected 250 km away from the F1NPP. Although we have not yet systematically studied the effect of radionuclides on the environment and wildlife, one of three Japanese Bush Warblers (Cettia diphone), captured in Akaugi district in August 2011, was observed to have a conspicuous lesion near the cloaca, which is rare in Japan. All of the birds' feathers were strongly contaminated. Further study is needed to determine the significance of this result. We emphasize the importance of continuing assessment of the effects of the F1NPP accident on wildlife. © The Author 2016.

    Survey on the consumption of leaf vegetables and milk by infants was carried out in Tokai village, which was one of the parameters used for the estimation of thyroid dose caused by iodine-131 released from stacks of nuclear facilities into the air. It was observed that unweaned babies had no leaf vegetables and were fed on milk only. The daily intake was estimated roughly as 1.1 liters. After weaning leaf vegetables consumption by infants increased with the age. On the contrary, milk consumption decreased with the age. The consumption of leaf vegetables and milk by each age group was as follows; 20 g/d/p and 600 ml/d/p for 0.5 to 1.5 years, 25 g/d/p and 300 ml/d/p for 1.5 to 3 years, 35 g/d/p and 300 ml/d/p for 3 to 5 years, and 50 g/d/p and 300 ml/d/p for 5 to less than 6 years old, respectively.

    We used new methods to examine differences in population-based cancer survival between six prefectures in Japan, after adjustment for age and stage at diagnosis. We applied regression models for relative survival to data from population-based cancer registries covering each prefecture for patients diagnosed with stomach, lung, or breast cancer during 1993-1996. Funnel plots were used to display the excess hazard ratio (EHR) for each prefecture, defined as the excess hazard of death from each cancer within 5 years of diagnosis relative to the mean excess hazard (in excess of national background mortality by age and sex) in all six prefectures combined. The contribution of age and stage to the EHR in each prefecture was assessed from differences in deviance-based R(2) between the various models. No significant differences were seen between prefectures in 5-year survival from breast cancer. For cancers of the stomach and lung, EHR in Osaka prefecture were above the upper 95% control limits. For stomach cancer, the age- and stage-adjusted EHR in Osaka were 1.29 for men and 1.43 for women, compared with Fukui and Yamagata. Differences in the stage at diagnosis of stomach cancer appeared to explain most of this excess hazard (61.3% for men, 56.8% for women), whereas differences in age at diagnosis explained very little (0.8%, 1.3%). This approach offers the potential to quantify the impact of differences in stage at diagnosis on time trends and regional differences in cancer survival. It underlines the utility of population-based cancer registries for improving cancer control.

    On March 11, 2011, a magnitude 9.0 earthquake occurred off of Japan's Pacific coast, which was followed by huge tsunamis that destroyed many coastal cities in the area. Due to the earthquake and subsequent tsunami, malfunctions occurred at the Fukushima Daiichi (Fukushima I) nuclear power plant, resulting in the release of radioactive material in the region. While recent studies have investigated the effects of these events on the mental health of adults in the region, no studies have yet been performed investigating similar effects among children. This study aims to fill that gap by: 1) assessing the mental health of elementary and middle school children living within the Fukushima prefecture of Japan, and 2) identifying risk and protective factors that are associated with the children's mental health scores. These factors were quantified using an original demographics survey, the Strengths and Difficulties Questionnaire (SDQ), and the Impact of Event Scale-Revised (IES-R), the latter two of which have been previously validated in a Japanese setting. The surveys were distributed to approximately 3,650 elementary and middle school students during the months of February and March, 2012. The data suggests that those children who had been relocated to the city of Koriyama had significantly higher SDQ scores than those children who were native to Koriyama (p natural disasters, younger children and those with parents suffering from trauma-related distress are particularly vulnerable to the onset of pediatric mental disturbances.

    This study aims to identify the factors that affect consumers purchasing behaviour towards food products that are free from Genetic Modified Organism (GM Free) in a European Region and more precisely in the Prefecture of Drama-Kavala-Xanthi. Field interviews conducted in a random selected sample consisted of 337 consumers in the cities of Drama, Kavala, Xanthi, in November and December of 2009. Principal components analysis (PCA) was conducted in order to identify the factors that affect people in preferring consuming products that are GM Free. The factors that influence people in the study area to buy GM Free products are: (a) products' certification as GM Free or organic products, (b) interest about the protection of the environment and nutrition value, (c) marketing issues, and (d) price and quality. Furthermore, cluster and discriminant analysis identified two groups of consumers: (a) those are influenced by the product price, quality and marketing aspects and (b) those are interested in product's certification and environmental protection. Non parametric statistical bivariate techniques were performed to profile the identified groups of consumers regarding their personal characteristics and some other factors affecting their buying behaviour.

    The importance of field learning has been increasing at elementary school and junior high school in Japan. However, In Japan, it is little actual situation that there is in an opportunity for the field learning enforced in the school science lesson. This tendency is strong as much as school of the city and that circumference. I think that this cause is that there are few suitable places for educational tool to observe geological field near the school. Children learn about "Function of running water" in Grade 5 of elementary school in Japan. Therefore, In this study, We remark the river called "Hiikawa-river" which flow in Izumo city, Shimane prefecture as the science teaching materials. Hiikawa is the river which flowing through the granitic rock district. Therefore We can observe granitic rock from in the upper stream, midstream, to the down stream. That is, we can observe the function of running water and diameter (size) of granitic boulders. It is mean that Hiikawa is the one of good educational tool for Children to learn the function of running water. Though it is the place where nature is comparatively rich even in Japan, it can't be said that field learning is relatively popular in Shimane prefecture. I think that teacher has to learning experience at field, because teacher should settle confidence to guide to the student at the field. That is, if it is not, you can not teach children with truly important of curriculum view point of natural and field science. In this research, we introduce practice of geological field learning at the public elementary school of the Shimane prefecture by using of Hiikawa as educational tool which children learn about the function of running water in grade 5, elementary school. In addition, we hope that this study contribute to teachers teaching method and to children natural science literacy.

    Radioactive nuclides emitted from the Fukushima Dai-ichi nuclear power plant were observed for the long term in Ohori River, Chiba Prefecture, Japan. In this presentation, we report time variation of concentrations of 134 Cs, 137 Cs and 129 I in the suspended soils (SS) and dissolved matter (DM) from the flow of the river were measured. The concentrations of radioactive cesium 134 and 137 in SS were gradually decreasing in long term observation and rising on the rainy day. The DM/SS ratios of 137 Cs were almost constant over time. In the DM, the 129 I data showed strong correlation with cesium data. (author)

    K-Ar age determination was made on a whole rock sample of the alunite-bearing silicified rock from the Iwato gold deposit, Kagoshima Prefecture, southern Japan. The sample is from one of the Nansatsu-type gold deposits, whose mineralization is characterized by the occurrence of leaching-type massive silicified rocks with gold dissemination. The result, 4.15 +- 0.78 Ma, is interpreted to be the age of the mineralization at the Iwato gold deposit. It also suggests that the Nansatsu-type deposits were formed in close association with andesitic volcanism in the early Pliocene age. (author)

    We previously surveyed indoor Rn concentration in homes throughout Aomori Prefecture from 1991 to 1995, and found a mean Rn concentration of 9 Bq m -3 . For accurate evaluation of radiation dose from Rn, its concentration not only in the home but also in workplaces and schools is important, since workers and students spend approximately one-third of the day in these places. Then, we obtained indoor Rn concentrations in several workplaces and schools in Aomori Prefecture. Now, measurements of outdoor Rn in workplaces have been planned for the prefecture during a two year period. The results for half the prefecture, the Nanbu area are described here. Passive Rn detectors using polycarbonate film were employed for long-term monitoring. Diurnal variations of Rn and its daughter nuclides were measured by an active Rn detector with an ionization chamber and a working level meter, respectively. The geometric mean Rn concentration obtained with the passive detectors was approximately 3 Bq m -3 in the outdoor workplaces, and lower than that in the indoor workplaces and school (14 Bq m -3 ). The Rn concentrations in fishing boats and harbors were slightly lower than typical values and some data for forests were higher than other workplaces. The diurnal variations which were higher at night and lower during the day were observed by the active detectors. (author)

    To tackle global climate stabilization concretely, we have developed a method formulating long-term scenarios towards a low-carbon economy at local level. As a result of the pioneering application of this method to Shiga Prefecture, we have found the following: (i) it is possible to design scenarios for moving towards a low-carbon economy in which CO 2 emission is lowered by 30-50% from the 1990 level by 2030, while the prefecture's gross production continues to grow by 1.6% annually; (ii) in order to halve the emission by 2030, socio-economic structural changes as well as technological measures are essential; and (iii) innovative measures at the prefectural level, such as land planning, renewable energy promotion and lifestyle change, play an increasingly important role as the target reduction rate gets higher

    In order to attain the 2010 target of reducing national greenhouse gases by 6% to the 1990 level, with reference to the Kyoto Protocol, the Government of Japan has planned and implemented some measures, as well as related policies. This paper discusses the possible impact of these measures on the nitrogen-oxide and sulfur-dioxide emissions from road vehicles in the Hiroshima Prefecture (ca. 3 million population). The number of road vehicles based on vehicle and fuel types in the Hiroshima Prefecture for 1990-2000 are presented, as well as projections for the years 2005 and 2010 using the Gompertz model. Three scenarios were developed to assess the emissions, referring to the possible achievement of related measures and policies as well as new vehicle technologies. Prediction results show that nitrogen-oxide emissions may be decreased from 14.7 kton in 1990 to 9.3 kton in 2010 if Japanese energy-policy and new vehicle developments are successfully implemented. If they are less successfully implemented, the emissions will decrease slightly to 14 kton, in which the decrease of emissions was mostly from gasoline vehicle. The emission of sulfur dioxide was projected to decrease from 1.2 kton in 1990 to within the range 0.45-0.49 kton by 2010, as a result of measures to reduce sulfur content in diesel oil

    General cogeneration and fuel cells are separately described in this guidebook. There is a view that a fuel cell is a highly efficient energy system in which both electric power and heat are effectively utilized, and it regards the fuel cell as representative of one of the utilization modes of cogeneration. Following this view, a fuel cell is given a position in parallel with general cogeneration. This guidebook expects that it will be read at private businesses and factories and various public departments within the prefecture where the introduction and utilization of general cogeneration and fuel cells are under study, and describes the procedures to follow when using the energy systems and names the offices to which the readers should refer as need arises. It also expects that people at large in the prefecture who are interested in general cogeneration and fuel cells will be among the readers, and various information is stated for them outlining the energy systems, explaining their merits, and mentioning cases of their application in the past.

    To study the HIV-1 genotypes and transmitted drug resistance (TDR) in Dehong prefecture of Yunnan province in 2013. Referring to the guidelines for HIV drug resistance threshold survey (HIVDR-TS), 54 plasma samples of recently reported HIV-infected individuals, aged between 16 and 25 years, were collected in Dehong prefecture from January to August 2013. Genotyping of partial pol gene was performed by using reverse transcriptional PCR. HIV-1 genotype. Prevalent levels of HIV-1 drug resistance transmission were analyzed. Forty-eight plasma samples were successfully sequenced and analyzed. Among them, 45.8% were Chinese and the rest 54.2% were all Burmese. Based on pol sequences, identified HIV genotypes included subtype C (41.7%), URF (31.3%), CRF01_AE (12.5%), CRF07_BC (10.4%), CRF08_BC (2.1%) and subtype B (2.1%), C subtype appeared dominated in Chinese while URF was dominated in Burmese. One drug resistant mutation to non-nucleoside reverse transcriptase inhibitors (NNRTIs) was detected in one sequence from Burmese. Based on the statistical method of HIVDR-TS, the prevalence of transmitted HIV-1 drug resistance was adjusted as scientific management for people living with HIV/AIDS should be strictly followed. Meanwhile, relevant surveillance, including drug resistance surveillance should also be performed among cross-border migrant population.

    The number of suicides in Japan has increased from approximately 22,000 per year in 1988-1997 to over 30,000 per year since then. It has also increased in Mie prefecture during that period. In the present study, we investigated the correlation between annual suicide rates in Mie prefecture, Japan from 1996-2002 and the annual unemployment rate in Japan from 1996-2002 among males. Among the results, annual suicide rates in total correlated with the unemployment rate in Japan, but the relation was not statistically significant: r(7)=0.76, r(2)(7)=0.58, p=0.05 (y=3.54x+6.37); the rates in males, however, correlated significantly with the unemployment rate in Japan: r(7)=0.85, r(2)(7)=0.73, p=0.01 (y=5.72x+4.49). In addition, we found that annual suicide rates in total correlated significantly with the male unemployment rates. When a patient is unemployed and in a bad situation, the medical staff and the family should be aware of the correspondence between suicide rates and unemployment.

  10. Ecosystem Services Evaluation and Its Spatial Characteristics in Central Asia’s Arid Regions: A Case Study in Altay Prefecture, China

    Full Text Available Ecosystem services are important foundations to realize the sustainable development of economy and society. The question of how to quantitatively evaluate ecosystem services in a scientific way is a hot topic among international researchers. Studying the spatial characteristics of ecosystem services in arid regions can provide the theoretical and practical basis for coordinating a sustainable man-land relationship. Altay Prefecture of China, a typical arid region in Central Asia, was taken as the study area. It is on the Silk Road economic belt, which is a key region in the program of developing Western China. Three ecosystem services: water yield, soil conservation, and net primary productivity were quantitatively evaluated. The results show that (1 the spatial distribution pattern has a distinct characteristic of zonality; (2 mountain zone and mountain-oasis ecotone are the hotspots of ecosystem services; and (3 the correlation between water yield and net primary productivity shows a gradual increasing trend as altitude decreases. Objective analysis from the aspect of mechanism is given by discussing the causes of this particular pattern. It is found that altitude and slope have great influence on spatial distributions of ecosystem services, zones with the most amount of services are distributed in 1.5–2 km-altitude and 15–25°-slope. Different human activities in different regions and spatial distance decay of ecosystem services also contribute to the formation of spatial pattern. Thus, overgrazing, logging and mining are prohibited in mountain zones and mountain-oasis ecotones. Scholars are encouraged to focus on desert-ecosystem services in the future.

    Highlights: • Superiority–inferiority full-infinite mixed-integer method is developed. • The method can tackle uncertainties of fuzzy sets, crisp and functional intervals. • The method is applied to a real case of planning energy system. • Effects of energy-conversion efficiency on energy systems are analyzed. • Results can support policy enactment of conversion efficiency improvement. - Abstract: In this study, a superiority–inferiority full-infinite mixed-integer programming (SFMP) method is developed for analyzing the effect of energy conversion efficiency under uncertainty. SFMP can effectively tackle uncertainties expressed as fuzzy sets, crisp intervals and functional intervals, it also can directly reflect relationships among multiple fuzzy sets through varying superiority and inferiority degrees with a high computational efficiency. Then the developed SFMP is applied to a real case of planning energy system for Bayingolin Mongol Autonomous Prefecture, where multiple scenarios related to different energy-conversion efficiency are concerned. Results for energy processing, energy conversion, capacity expansion, pollutant emission and system cost have been generated. It is proved that SFMP is an effective approach to deal with the uncertainties in energy systems with interactive and uncertain characteristics. A variety of uncertainties existed in energy conversion processes and impact factors could affect the modeling result. Results show that improvement of energy-conversion efficiency can effectively facilitate reducing energy resources consumption, optimizing energy generation pattern, decreasing capacity expansion, as well as mitigating pollutant emissions. Results also reveal that, for the study area, electric power has a highest energy saving potential among heating, oil processing, coal washing and refining. Results can help decision makers to generate desired alternatives that can facilitate policy enactment of conversion efficiency

    We compile the important points to evaluate earthquake source fault in active folding zone through a temporary aftershock observation of the 2004 Mid-Niigata Prefecture earthquake. The aftershock distribution shows spindle shape whose middle part is wide and both ends are narrow in NNE-SSW trending. The range of seismic activity corresponds well to the distribution of fold axes in this area, whose middle part is anticlinorium (some anticlines) and both ends are single anticline. In the middle part, the west dipping aftershock plane including the mainshock (M6.8) is located under the Higashiyama anticline. Another west dipping aftershock plane including the largest aftershock (M6.5) is located under the Tamugiyama and Komatsugura anticlines, and the east margin of the aftershock distribution corresponds well with Suwa-toge flexure. Therefore the present fold structure should have been formed by an accumulation of the same faults movement. In other words, it is important to refer the fold axes distribution pattern, especially with flexure, for the evaluation of earthquake source fault. In addition, we performed FEM analyses to investigate the relation of fold structure to the thickness of the sedimentary layer and the dip angle of the fault. Reverse fault movement forms asymmetric fold above the fault, which steeper slope is formed just above the upper end of the fault. As the sedimentary layer became thicker, anticline axis moved to hanging wall side in the fold structure. As the dip angle became smaller, the wavelength of the fold became longer and the fold structure grew highly asymmetric. Thus the shape of the fold structure is useful as an index to estimate the blind thrust below it. (author)

    Full Text Available We assessed HIV/AIDS expenditures in Dehong Prefecture, Yunnan Province, one of the highest prevalence regions in China, and describe funding sources and spending for different categories of HIV-related interventions and at-risk populations.2010 HIV/AIDS expenditures in Dehong Prefecture were evaluated based on UNAIDS' National AIDS Spending Assessment methodology.Nearly 93% of total expenditures for HIV/AIDS was contributed by public sources. Of total expenditures, 52.7% was allocated to treatment and care, 24.5% to program management and administration and 19.8% to prevention. Spending on treatment and care was primarily allocated to the treatment of opportunistic infections. Most (40.4% prevention spending was concentrated on most-at-risk populations, injection drug users (IDUs, sex workers, and men who have sex with men (MSM, with 5.5% allocated to voluntary counseling and testing. Prevention funding allocated for MSM, partners of people living with HIV and prisoners and other confined populations was low compared to the disproportionate burden of HIV/AIDS in these populations. Overall, people living with HIV accounted for 57.57% of total expenditures, while most-at-risk populations accounted for only 7.99%.Our study demonstrated the applicability of NASA for tracking and assessing HIV expenditure in the context of China, it proved to be a useful tool in understanding national HIV/AIDS response from financial aspect, and to assess the extent to which HIV expenditure matches epidemic patterns. Limited funding for primary prevention and prevention for MSM, prisoners and partners of people living with HIV, signal that resource allocation to these key areas must be strengthened. Comprehensive analyses of regional and national funding strategies are needed to inform more equitable, effective and cost-effective HIV/AIDS resource allocation.

    Recently in Japan, many investigations to grasp the ways of thinking in the national layers for energy, environment and radiation applications have been carried out. In the investigations for radiation applications, there is a pointing out that the age which the knowledge on radiations and their related matters is formed is predominantly in elementary school years. Therefore, in order to find out the future way of proceeding with the education of nuclear power and radiations in the curriculums of elementary and junior high schools, the questionnaire survey on radiations and their related matters was carried out for the public elementary and junior high school students in Kagoshima prefecture. The results of the questionnaire survey are summarized in the present paper. (K. Kato)

    China has experienced great social and economic vicissitudes that caused the vast complexity and uncertainty for electricity consumption. This paper attempts to identify the main determinants of the electricity consumption intensity by using the data from Chinese cities at subprovince and prefecture levels in 2009. The key category factors, including urban morphology, industrial structure, regulation context, urbanization degree, price, natural condition, and resource endowment, are abstracted and the influence of these determinants is evaluated by adopting the finite mixture models. The variation of each determinant across regions, the comparative weights of all the factors, and the detailed classifications of the cities are reported for facilitating the understanding of electricity consumption in China. The corresponding policies for electricity administration are addressed as well. PMID:22927781

    Guinea is the third hardest hit country in the region with 2,806 cases and 1,814 deaths as of January 11, 2015 after Sierra Leone and Liberia respectively. This KAP study was conducted in three sub-prefectures of Kouroussa in the Kankan region of Guinea from 15 December 2014 to 15 January 2015. It was conducted with the general objective of examining the knowledge, attitude and practice related to Ebola prevention and care among the public of Kouroussa Prefecture. A cross-sectional study design was employed to collect quantitative data to examine knowledge, attitude and practice related to Ebola. Structured questionnaire was administered by trained data collectors who were supervised by doctors and epidemiologists from WHO and Africa Union. Data were collected from 358 individuals (93% response rate) and analyzed in STATA 13 while tables and graphs are used to display results. Over 96% of the respondents have ever heard about Ebola while only 76.2% believed the disease existed in Kouroussa. Avoiding physical contacts including hand shaking and contacts with body fluids, and early treatment of persons sick from Ebola were the two important prevention methods frequently mentioned (96.8% and 93.9%). Only 35.7% of respondents were found to have comprehensive knowledge about Ebola (composite of correctly accepting three methods of prevention (85%) and rejecting misconceptions (55.7%)). The high level of knowledge about modes of transmission and prevention methods has not positively affected the level of comprehensive knowledge about Ebola. In contrast, the prevailing high level of misconceptions surrounding Ebola was found to be responsible for a low comprehensive knowledge.

    Japan has been free from rabies since the 1950s. However, during the early 1900s several large-scale epidemics spread throughout the country. Here we investigate the dynamics of these epidemics between 1914 and 1933 in Osaka Prefecture, using archival data including newspapers. The association between dog rabies cases and human population density was investigated using Mixed-effects models and epidemiological parameters such as the basic reproduction number (R0), the incubation and infectious period and the serial interval were estimated. A total of 4,632 animal rabies cases were reported, mainly in dogs (99.0%, 4,584 cases) during two epidemics from 1914 to 1921, and 1922 to 1933 respectively. The second epidemic was larger (3,705 cases) than the first (879 cases), but had a lower R0 (1.50 versus 2.42). The first epidemic was controlled through capture of stray dogs and tethering of pet dogs. Dog mass vaccination began in 1923, with campaigns to capture stray dogs. Rabies in Osaka Prefecture was finally eliminated in 1933. A total of 3,805 rabid dog-bite injuries, and 75 human deaths were reported. The relatively low incidence of human rabies, high ratio of post-exposure vaccines (PEP) and bite injuries by rabid dogs (minimum 6.2 to maximum 73.6, between 1924 and 1928), and a decline in the proportion of bite victims that developed hydrophobia over time (slope = -0.29, se = 3, p dog rabies cases were detected at higher human population densities (slope = 0.66, se = 0.03, p dog rabies cases detected per capita (slope = -0.34, se = 0.03, p dog movement enabled by strong legislation was key to eliminate rabies. Moreover, the prominent role of the media in both reporting rabies cases and efforts to control the disease likely contributed to promoting the successful participation required to achieve rabies elimination.

    The importance of learning at field has been increasing in the elementary and the junior high school in Japan. And, an environmental education is one of the important subjects even in the school education, too. It was important, as for science education, understanding with actual feeling and learning were specified as for the Teaching outlines (the Japanese Ministry of Education, Culture, Sports, Science and Technology) of the new science textbook of the elementary and the junior high school as well. However, It is a little actual situation that there is in an opportunity for the field learning enforced in the school lesson by the investigation of JST (Japan Science and Tecnology Agency). This tendency is strong as much as school of the city and that circumference. I have this cause think that there are a few suitable places for learning to observe geological and biological field near school. In addition, below two is pointed out as a big problem to obstruct the execution of field learning. 1) A natural experience isn't being done sufficient as much as a teacher can teach to the student. 2) It doesn't have the confidence that a teacher teaches a student geology and biology at the field. I introduce the practical example of geological field learning at the public elementary school of the Shimane prefecture by this research. Though it is the place where nature is comparatively rich even in Japan, it can't be said that field learning is popular in Shimane prefecture. A school teacher has to learning experience at field, and he must settle confidence to guide a student at the field. A specialist in the university and the museum must support continuous learning for that to the school teacher.

    This report describes our onsite medical rounds and fact-finding activities conducted in the acute phase and medical relief work conducted in the subacute phase in Miyagi prefecture following the Great East Japan Earthquake and subsequent tsunami that occurred off northeastern Honshu on March 11, 2011. As part of the All-Japan Hospital Association medical team deployed to the disaster area, a Nippon Medical School team conducted fact-finding and onsite medical rounds and evaluated basic life and medical needs in the affected areas of Shiogama and Tagajo. We performed triage for more than 2,000 casualties, but in our medical rounds of hospitals, clinics, and nursing homes, we found no severely injured person but did find 1 case of hyperglycemia. We conducted medical rounds at evacuation shelters in Kesennuma City during the subacute phase of the disaster, from March 17 through June 1, as part of the Tokyo Medical Association medical teams deployed. Sixty-seven staff members (17 teams), including 46 physicians, 11 nurses, 3 pharmacists, and 1 clinical psychotherapist, joined this mission. Most patients complained of a worsening of symptoms of preexisting conditions, such as hypertension, respiratory problems, and diabetes, rather than of medical problems specifically related to the tsunami. In the acute phase of the disaster, the information infrastructure was decimated and we could not obtain enough information about conditions in the affected areas, such as how many persons were severely injured, how severely lifeline services had been damaged, and what was lacking. To start obtaining this information, we conducted medical rounds. This proved to be a good decision, as we found many injured persons in evacuation shelters without medication, communication devices, or transportation. Also, basic necessities for life, such as water and food, were lacking. We were able to evaluate these basic needs and inform local disaster headquarters of them. In Kesennuma City, we

    Flood is one of the most significant natural hazards in Japan. The Tokyo metropolitan area has been affected by several large flood disasters. Therefore, investigating potential flood risk in Tokyo metropolitan area is important for development of adaptation strategy for future climate change. We aim to develop a method for evaluating flood risk in Tokyo Metropolitan area by considering effect of historical land use and land cover change, socio-economic change, and climatic change. Ministry of land, infrastructure, transport and tourism in Japan published 'Statistics of flood', which contains data for flood causes, number of damaged houses, area of wetted surface, and total amount of damage for each flood at small municipal level. By using these flood data, we estimated damage by inundation inside a levee for each prefecture based on a statistical method. On the basis of estimated damage, we developed flood risk curves in the Tokyo metropolitan area, representing relationship between damage and exceedance probability of flood for the period 1976-2008 for each prefecture. Based on the flood risk curve, we attempted evaluate potential flood risk in the Tokyo metropolitan area and clarify the cause for regional difference of flood risk. By analyzing flood risk curves, we found out regional differences of flood risk. We identified high flood risk in Tokyo and Saitama prefecture. On the other hand, flood risk was relatively low in Ibaraki and Chiba prefecture. We found that these regional differences of flood risk can be attributed to spatial distribution of entire property value and ratio of damaged housing units in each prefecture.We also attempted to evaluate influence of climate change on potential flood risk by considering variation of precipitation amount and precipitation intensity in the Tokyo metropolitan area. Results shows that we can evaluate potential impact of precipitation change on flood risk with high accuracy by using our methodology. Acknowledgments

    Floods, the most common natural disaster in the world, cause serious loss of life and economic damage. Flood is one of the disasters in the coastal lowland along the Kujukuri Plain, Chiba Prefecture, Japan. Many natural and human activities have changed the surface environment of the Plain. These include agricultural development, urban and industrial development, change of the drainage patterns of the land surface, deposition and/or erosion of the river valleys, and so on. In addition, wide spread occurrence of land subsidence has been caused by the abstraction of natural gas dissolved in groundwater. The locations of the groundwater extraction include nearby the coast, and it may increase the flood risk. Hence, it is very important to evaluate flood hazard by taking into account the temporal change of land elevation caused by land subsidence, and to develop hazard maps for protecting surface environment and land-use planning. Multicriteria decision analysis (MCDA) provides methodology and techniques for analyzing complex decision problems, which often involve incommensurable data or criteria. Also, Geographical Information System (GIS) is the powerful tool since it manages large amount of spatial data involved in MCDA. The purpose of this study is to present a flood hazard model using MCDA techniques with GIS support in a region where primary data are scare. The model incorporates six parameters: river system, topography, land-use, flood control project, passing flood from coast, and precipitation. Main data sources used are 10 meter resolution topography data, airborne laser scanning data, leveling data, Landsat-TM data, two 1:30,000 scale river watershed map, and precipitation data from precipitation observation stations around the study area. River system map was created by merging the river order, the line density, and the river sink point density layers. Land-use data were derived from Landsat-TM images.

    The experiment and survey were carried out to verify the effectiveness and limitation of MT method. The previous seismic reflection method is unsuitable for steep terrain and over-folded complicated geological structure. In such difficult areas, application of MT method is increasing as complement or substitution for the reflection method. However, the evaluation of resistivity structure interpretation for every area is slightly difficult because of lack of data, poor quality of data, and no verification data at boreholes. Consequently, the survey was again carried out in well-known Yurihara oil and gas field, Akita prefecture whose geological structure has been surveyed in detail at boreholes, by adding new 32 sites, 22 sites on the south side and 10 sites on the north side of the measuring line extending from east to west. As a result, it was clarified that the lower high-resistivity layer found by MT method is equal to the Nishikurosawa basaltic layer, and basalt extends to the west in the north area. This result can`t be simply compared with the previous geological profile. 8 refs., 8 figs.

Although significantly more dog rabies cases were detected at higher human population densities (slope = 0.66, se = 0.03, p < 0.01, there were fewer dog rabies cases detected per capita (slope = -0.34, se = 0.03, p < 0.01. We suggest that the combination of mass vaccination and restriction of dog movement enabled by strong legislation was key to eliminate rabies. Moreover, the prominent role of the media in both reporting rabies cases and efforts to control the disease likely contributed

    CRF07_BC is one of the most prevalent HIV-1 strains in China, and Xinjiang Uygur Autonomous Region has ever been considered to be a second epidemic center after Yunnan Province in previous studies. Here we use HIV-1 pol gene sequences identified from Hetian Prefecture located in Xinjiang Autonomous Region to reconstruct the epidemic history of HIV CRF07_BC strain circulating in this region. We found that CRF07_BC is the predominant HIV-1 form in Hetian Prefecture, and the estimated tMRCA analysis shows that there is no enough evidence supporting Xinjiang Autonomous Region as a second epidemic center of spreading HIV-1. It may imply that every city may be only a point among the HIV spreading network because of the frequent migration of population in the whole country nowadays.

    Full Text Available The rapid urbanization has exerted tremendous pressure on natural systems in mountains. As a measure of sustainable use of natural resources, ecological footprint is an important basis for judging whether the development of a country or region is within the bio-capacity. Taking Dali Bai Autonomous Prefecture as an example, this study comprehensively analyzes the impact of human activities on mountain resources and environment from the three aspects of urbanization, land use and ecological carrying capacity. The results show that Dali Prefecture with the urbanization rate of 33% is still in the accelerated stage of urbanization. The urban space presents the core-periphery feature, and the central city is the focus of human existence and living activities. The per capita ecological footprint is 1.14 ha higher than the ecological carrying capacity, meaning Dali Prefecture has an ecological deficit. This indicates that there is an uncoordinated state between urbanization and environment. Arable land is the main source of per capita ecological footprint in the prefecture. However, the urban expansion overly occupies the arable land in the plain sub-region, leading the arable land to an ecological deficit state. In the future, the development of the mountainous area should focus on the protection of arable land and choose a new sustainable path.

    The authors studied optimal methods against the Cs contamination of agricultural reservoirs outside the evacuation zones, which had been contaminated by the accident of Fukushima Daiichi Nuclear Power Station. As a result of measurements at three points of a small reservoir, the highest radioactivity value was 16.8 Bq/g, with a higher value at bank part and bottom mud. The possibility is considered that the bank part held an organic layer with accumulated Cs, and the bottom mud had litters and clay soil that adsorbed Ce. The distribution of Cs was fluctuated depending on the environment of reservoirs, with the effects of the influx of sediment, influx of litters, and landform of catchment areas. In the 'Technical manual on measures against radioactive materials at reservoirs,' published by the Ministry of Agriculture, Forestry and Fisheries, three decontamination methods for reservoirs have been taken up: (1) removal of mud, (2) fixation of bottom mud, and (3) improvement of water intake method. The method (1) and (2) alone cannot cope with re-contamination from water catchment areas. As a countermeasure for recontamination after decontamination, it is good to install a headrace channel, slope, retaining part, etc. at the pond bottom, to increase the efficiency of the recollection and immobilization of Ce. The felling of neighboring trees, litter collection in peripheral areas, and covering measures for the surface layer in the vicinity are essential. (A.O.)

    To understand the nutritional status and related factors of Tujia and Miao minority primary school students in Xiangxi Autonomous Prefecture and to provide refrence for the improvement of minority students' nutritional status. By the method of layered and random sampling, physique test and questionnaire survey were taken to 682 Tujia students and 420 Miao students, the nutritional level of students were estimated by the method of height with standard weight. Logistic regression analysis was used to analyze the risk factors of nutritional status. The moderate malnutrition rate was 4.54% and the obesity rate was 11.43%. Logistic regression analysis showed that monthly income per capita (OR = 1.368, 95% CI 1.135-1.648) and culture level of fathers (OR = 1.332, 95% CI 1.108-1.602) were independent risk factors of malnutrition, children with family obesity history (OR =7.688, 95% C15. 134-11.513), monthly income per capita (OR = 1.516, 95% CI 1.204-1.910) and culture level of fathers (OR = 1.466, 95% CI 1.164-1.846 ) were independent risk factors of overnutrition. Malnutrition and overnutrition exist in Tujia and Miao students at the same time, family obesity history, monthly income per capita and culture level of fathers are factors of malnutrition and overnutrition. Nutritional education should be taken universal to students and their guardians.

    To evaluate the properties of algae to concentrate radioactive elements, 14 species of algae like Sargassum were collected in the Prefecture and analyzed for their {sup 232}Th and {sup 238}U levels with Yokogawa HP4500 ICP-MS apparatus. The places of collection included those near the water discharge of an atomic power station. Mean {sup 232}Th and {sup 238}U levels were found to be 120 and 260 ng/g dry wt, respectively, and Phaeophyta showed more than several times higher {sup 238}U level than Chlorophyta and Rhodophyta. There was no clear difference in {sup 232}Th levels. No difference between places of collection was observed in Sargassum {sup 232}Th or {sup 238}U level. Adsorption of {sup 232}Th particle to and incorporation of soluble {sup 238}U into algae body were suggested. Mean {sup 232}Th and {sup 238}U radioactivities were found 73 and 510 {mu}Bq/g wet wt, respectively, and the respective annual committed effective doses, 0.2 and 0.3 {mu}Sv, calculated from those values were confirmed to be enough lower than the annual public dose limit, 1 mSv.

    The aim of this study was to investigate 12 perfluorinated compounds (PFCs) including perfluorinated carboxylates (C4-C12) and perfluorinated alkyl sulfonates (C4, C6, and C8) in river and seawater samples to determine contamination levels in the aquatic environment of Hyogo prefecture, Japan. High levels of perfluorohexanoic acid (PFHxA; 2300-16,000 ng/L) were detected in the Samondogawa River at Tatsumi Bridge downstream of a PFC production facility; this location also had the highest mass flow rate of PFCs (3900-29,000 kg/y). Widespread contamination of coastal waters was confirmed with PFHxA as the dominant compound. Perfluorooctanoic acid was also prevalent in coastal waters. The concentration of PFHxA in coastal seawater and the distance from the mouth of the Samondogawa River were inversely related. This discharge of high concentrations of PFHxA from the Samondogawa River may have affected concentrations of PFCs in Osaka Bay. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Radioactive nuclides with a short half-life, such as (131)I and (134)Cs, were detected in environmental samples collected in Aomori Prefecture after the Tokyo Electric Power Company Fukushima Dai-ichi Nuclear Power Plant accident in March 2011. In addition, the observed (137)Cs concentration was increased over the background level. The gaseous (131)I concentration in air observed in April was higher than that observed in March immediately after the accident. Using a backward trajectory analysis, the authors found that the air mass had passed the vicinity of the Fukushima Dai-ichi Nuclear Power Plant when the gaseous (131)I concentration in air was increasing. Maximum (131)I and radioactive Cs concentrations in daily fallout samples collected in Aomori city were observed on 28 April, when (131)I was also detected in air. (134)Cs and (137)Cs concentration ratios in pine needles and pasture grass were nearly equal to 1, which indicates that the source of these radionuclides was the nuclear power plant accident. © The Author 2015.

    A comparative study was made on mortality during a 15-year period from 1968 to 1982 between atomic bomb survivors resident in Hiroshima Prefecture and non-exposed controls. The mortality rate for all causes of death was lower in atomic bomb survivors than in the non-exposed, but the rate was higher among those directly exposed within about 1 km than in the non-exposed. The mortality rate for malignant neoplasms was higher in atomic bomb survivors than in the non-exposed, but that for cerebrovascular disease and heart disease was lower. In examining the rate for malignant neoplasms by site, the sites showing a high mortality rate among atomic bomb survivors were almost identical to the results of the Life Span Study. For these sites, the shorter the exposure distance the higher was the mortality rate. The rate for malignant neoplasms of the uterus and stomach, and leukemia was unnaturally high among early entrants whose period after issuance of atomic bomb survivor's health handbook was short. In observing the atomic bomb survivors by the level of family destruction due to the bombing as a socio-economic factor, a tendency was observed for the mortality rate for malignant neoplasms, diseases of blood and blood-forming organs, and peptic ulcer, to be higher among survivors with severe family destruction.

  1. An Improved Neural Network for Regional Giant Panda Habitat Suitability Mapping: A Case Study in Ya’an Prefecture

    2014-06-01

    Full Text Available Expert knowledge is a combination of prior information and subjective opinions based on long-experience; as such it is often not sufficiently objective to produce convincing results in animal habitat suitability index mapping. In this study, an animal habitat assessment method based on a learning neural network is proposed to reduce the level of subjectivity in animal habitat assessments. Based on two hypotheses, this method substitutes habitat suitability index with apparent density and has advantages over conventional ones such as those based on analytical hierarchy process or multivariate regression approaches. Besides, this method is integrated with a learning neural network and is suitable for building non-linear transferring functions to fit complex relationships between multiple factors influencing habitat suitability. Once the neural network is properly trained, new earth observation data can be integrated for rapid habitat suitability monitoring which could save time and resources needed for traditional data collecting approaches through extensive field surveys. Giant panda (Ailuropoda melanoleuca natural habitat in Ya’an prefecture and corresponding landsat images, DEM and ground observations are tested for validity of using the methodology reported. Results show that the method scores well in key efficiency and performance indicators and could be extended for habitat assessments, particularly of other large, rare and widely distributed animal species.

    A new fossil filefish, Aluterus shigensis sp. nov., with a close resemblance to the extant Aluterus scriptus (Osbeck), is described from the Middle Miocene Bessho Formation in Nagano Prefecture, central Japan. It is characterized by: 21 total vertebrae; very slender and long first dorsal spine with tiny anterior barbs; thin and lancet-shaped basal pterygiophore of the spiny dorsal fin, with its ventral margin separated from the skull; proximal tip of moderately slender first pterygiophore of the soft dorsal fin not reaching far ventrally; soft dorsal-fin base longer than anal-fin base; caudal peduncle having nearly equal depth and length; and tiny, fine scales with slender, straight spinules. The occurrence of this fossil filefish from the Bessho Formation is consistent with the influence of warm water currents suggested by other fossils, but it is inconsistent with the deep-water sedimentary environment of this Formation. This is the first fossil occurrence of a filefish in Asia; previously described fossil filefishes are known from the Pliocene and Pleistocene of Italy, the Pliocene of Greece, and the Miocene and Pliocene of North America. These fossil records suggest that the genus Aluterus had already been derived and was widely distributed during the Middle Miocene with taxa closely resembling Recent species.

    The rate of participation in breast cancer screening carried out by inspection and palpation associated with mammography in Kyoto Prefecture has been still low. In order to decrease the rate of breast cancer death, a high rate of screening participation must be achieved. We have organized the Kyoto Executive Committee of Pink Ribbon Activity aiming at the goal of achieving a 50% rate of participation in mammography screening by the end of 2010, and undertaken the following campaign activities: performing free screening, distribution and display of posters and leaflets about breast cancer screening, cooperation with various media to spread educational and informative messages, cooperation with a commercial institute in Kyoto City to distribute useful information, performing free breast cancer screening, and holding public lecture meetings, distribution of leaflets at student festivals at universities and colleges in Kyoto, and holding a ''Pink Ribbon symposium'' in a cosponsored company. All the above projects were performed successfully and many participants attended. We will continue these activities until the 50% participation rate is achieved. (author)

    The purpose of this study was to explore the factors related to earthquake preparedness in Japanese hemodialysis patients. We focused on three aspects of the related factors: health condition factors, social factors, and the experience of disasters. A mail survey of all the members of the Japan Association of Kidney Disease Patients in three Japanese prefectures (N = 4085) was conducted in March, 2013. We obtained 1841 valid responses for analysis. The health factors covered were: activities of daily living (ADL), mental distress, primary renal diseases, and the duration of dialysis. The social factors were: socioeconomic status, family structure, informational social support, and the provision of information regarding earthquake preparedness from dialysis facilities. The results show that the average percentage of participants that had met each criterion of earthquake preparedness in 2013 was 53%. Hemodialysis patients without disabled ADL, without mental distress, and requiring longer periods of dialysis, were likely to meet more of the earthquake preparedness criteria. Hemodialysis patients who had received informational social support from family or friends, had lived with spouse and children in comparison to living alone, and had obtained information regarding earthquake preparedness from dialysis facilities, were also likely to meet more of the earthquake preparedness criteria. © 2017 International Society for Apheresis, Japanese Society for Apheresis, and Japanese Society for Dialysis Therapy.

    It remains challenging to forecast local, seasonal outbreaks of influenza. The goal of this study was to construct a computational model for predicting influenza incidence. We built two computational models including an Autoregressive Distributed Lag (ARDL) model and a hybrid model integrating ARDL with a Generalized Regression Neural Network (GRNN), to assess meteorological factors associated with temporal trends in influenza incidence. The modelling and forecasting performance of these two models were compared using observations collected between 2006 and 2015 in Nagasaki Prefecture, Japan. In both the training and forecasting stages, the hybrid model showed lower error rates, including a lower residual mean square error (RMSE) and mean absolute error (MAE) than the ARDL model. The lag of log-incidence, weekly average barometric pressure, and weekly average of air temperature were 4, 1, and 3, respectively in the ARDL model. The ARDL-GRNN hybrid model can serve as a tool to better understand the characteristics of influenza epidemic, and facilitate their prevention and control.

    The present study investigated the association between the structure of catheter replacement services in home medical care settings and regional characteristics. An anonymous self-administered questionnaire was carried out from August to September 2013. Participants were physicians from 5338 clinics that provided medical care services at home, and nurses from 1619 home-visit nursing stations in Tokyo and three adjoining prefectures. The questionnaire covered catheter replacement (gastrostomy tubes, nasogastric tubes, tracheal cannulas) during home medical care, and the professions of those who replaced urethral catheters for male and female patients. Regions were divided into two groups (higher- and lower-density regions) based on the number of clinics, number of home-visit nursing stations and the ratio of the population aged ≥65 years. The rates of respondents that reported catheter replacement was usually executed, and those who reported catheters were replaced by "physicians in principle" were compared between the groups. Responses were received from 842 clinics (16.3%) and 499 home-visit nursing stations (31.4%). In the higher-density regions, the rate of physicians who reported urethral catheters for male patients were replaced by "physicians in principle" was significantly higher than in the lower-density regions (P home medical care settings, urethral catheters for male patients are replaced by nurses in regions where physician resources are limited.

    Full Text Available Methadone maintenance treatment (MMT was introduced to China in 2004 to reduce the harm of injecting drug users (IDUs. However, little is known about continued drug use, especially methamphetamine (MAMP, among MMT patients.A survey was conducted among patients attending five major MMT clinics in Dehong Prefecture in 2014 to investigate the heroin and MAMP use and their associated risk factors. Participants were administered with face-to-face interviews, and urine tests for morphine and MAMP.A total of 2,121 were eligible and participated in the study. Among them, 220 (10.4% were only positive for morphine, 12.9% were only positive for MAMP, and 196 (9.2% were positive for both morphine and MAMP. Compared with neither use of heroin nor MAMP during MMT, heroin use (not using MAMP was associated with ethnicity, shorter duration of MMT, lower dose of methadone, and having had no more than two sex partners in the past year; MAMP use (not using heroin was associated with ethnicity, longer duration of MMT, higher dose of methadone and being aged <30 years (vs. ≥50 years; use of both heroin and MAMP was associated with being Dai minority (vs. Han, a marital status of divorced or widowed, having used drugs for ≥10 years and shorter duration of MMT.These findings indicate the complexity in the treatment of heroin users and underscore the importance in prescribing appropriate methadone dosages in order to reduce both heroin and MAMP use.

    Full Text Available Toxoplasmosis is a worldwide zoonosis caused by Toxoplasma gondii, which can infect warm-blooded animals and humans. The present study was performed to investigate the seroprevalence of T. gondii in horses in Xinjiang, northwestern China. A total of 637 blood samples were collected from seven regions in Changji Hui Autonomous Prefecture, Xinjiang in 2011 and assayed for T. gondiiantibodies using the modified agglutination test (MAT. Risk factors (age, gender, and region related to seroprevalence were determined by a multivariate logistic regression analysis. A total of 200 horses (31.4%, 95% CI 27.79–35.00 were seropositive for T. gondii. Age, gender, and region present no association with seroprevalence (p>0.05 in the logistic regression analysis. The results indicated that T. gondii is widely prevalent in horses in Xinjiang, northwestern China, representing a serious threat to animal and human health. Therefore, more careful measures should be performed to control and prevent T. gondii infection in horses from Xinjiang, northwestern China.

    To reveal the effect of age and other factors on perceived anxiety over radiation exposure among decontamination workers in Fukushima Prefecture, Japan. A survey questionnaire was sent to 1505 workers, with questions regarding age, presence of a written employment contract, previous residence, radiation passbook ownership, presence of close persons for consultation, knowledge of how to access public assistance, and a four-point scale of radiation-related anxiety (1= "Very much," 2= "Somewhat," 3= "A little bit," and 4= "None" ). The relationships between the degree of anxiety and variables were analyzed using the chi-square test and residual analysis. In all, 512 participants responded to the questionnaire. The mean age of participants was 46.2 years (SD: 13.1, range: 18-77). Of them, 50, 233, 168, and 61 workers chose "Very much," "Somewhat," "A little bit," and "None," respectively, on the anxiety scale. Chi-square test showed that participants aged 61 years and over had higher degrees of anxiety (p<0.001). Ordinal logistic regression showed that the degree of anxiety increased if they did not have a written contract (p=0.042) or persons to consult (p=0.034) and if they routinely checked the dose rate (p=0.046). Decontamination workers who do not have a written contract or who are in socially isolated situations have greater anxiety over radiation exposure. Thus, it is important to both create supportive human relationships for consultation and enhance labor management in individual companies.

    This study describes an ecological study that evaluated the combined effects of working hours, income, and leisure time on suicide in all 47 prefectures of Japan. In men, the age-adjusted rate of suicide (per 100,000 population) was significantly correlated with working hours (r=0.587, pincome (r=-0.517, p=0.0002) and times for the leisure activities of self-education (r=-0.447, p=0.0016) and hobbies (r=-0.511, p=0.0002). In addition, a stepwise multiple regression analysis identified time for leisure social activities as a determining factor in suicide rate, even after adjusting for working hours and income. However, the impact of time for leisure social activities on suicide rate was smaller than that of working hours and income. In contrast, none of these factors affected suicide rate in women. These results suggest that increasing leisure time may be useful for preventing suicide among men in Japan.

    In recent years there have been over 30000 suicides annually in Japan. This is one of the most serious problems for Japanese society. Because mental disorder is closely associated with suicide, factors related to the increase in mental disorders and suicides should be clarified. In this study, various data regarding social factors were evaluated to assess the correlation of the number of patients with mental disorders and suicides among the 47 prefectures of Japan. Various data regarding social factors, such as income, savings, or rate of divorce, were obtained from the database of the Ministry of Health, Labour and Welfare of Japan. Among the factors, the annual income and the amount of savings were significantly correlated with the number of patients with mental disorder. On the other hand, while the annual income did not have a significant correlation with suicides, the amount of savings had a significant correlation with suicides. In conclusion, the annual income and amount of savings may both be one of the important factors involved in mental disorders, and the savings may also be a factor affecting suicides. These analyses are valuable in helping to clarify the causes of mental disease, and can hopefully contribute to the health and welfare of Japanese.

    The amount of energy in existence is theoretically the amount of energy that exists in a given region while the available amount is an amount of energy worked out with technological, economic, and social conditions taken into consideration. The total of the amount in existence and that of the available amount are mentioned in a table, and the available amount is further shown in terms of calorie. It totals 11,120Tcal per year, which is equivalent to approximately 55% of the whole amount of energy that Tokushima Prefecture demands. The availability of each type of new energy and the state of development of related technologies are studied to determine what priority is to be given to what energy. The group that is given the highest priority consists of photovoltaic power generation, passive solar systems, refuse fueled power generation, and heat from wastes (this group occupying more than 80% of the available amount in Tokushima Prefecture). The second group consists of wind power generation, clean energy vehicles, cogeneration, and small and medium scale hydroelectric power generation. The third group consists of fuel cells, ocean energy, biomass, and temperature difference energy. Natural conditions surrounding new energy in existence in Tokushima Prefecture are rather favorable, but social conditions are not. (NEDO)

    Large quantities of radioiodine and radiocesium were released from the accident at the Fukushima Daiichi Nuclear Power Plant (FDNPP) in March 2011. We have carried out intensive studies on the distribution and behaviour of these nuclides in the environment following the accident. Two topics obtained from our studies are presented. (1) Retrospective estimation of I-131 deposition through the analysis of I-129 in soil: It is necessary to obtain deposition data of radioiodine in Fukushima Prefecture for the assessment of thyroid doses due to the accident. However, short half-life of I-131 (8 days) made it impossible to obtain adequate sample coverage that would permit direct determination of the regional deposition patterns of I-131 within the prefecture and surrounding areas. On the other hand, I-129 released simultaneously during the accident still remains in soil, due to its long half-life of 1.57x10{sup 7} years. In order to reconstruct the I-131 deposition, we have determined I-129 concentrations by accelerator mass spectrometry (AMS). A good correlation was found between the measured concentrations of I-131 and I-129 in soils collected in the vicinity of FDNPP. We have analyzed I-129 in more than 500 soil samples collected systematically from Fukushima Prefecture. Using the obtained results, the I-131 deposition was calculated in different areas and the deposition map for I-131 was constructed. We also studied the vertical distribution of I-129 in soil. (2) Peculiar accumulation of radiocesium to some plants and mushrooms The radioactivity levels in agricultural crops decreased markedly in some months following the accident and their concentrations became lower than the Japanese guideline for foodstuffs (500 Bq/kg in 2011, and 100 Bq/kg after 2012). However, some agricultural products such as tea leaves and citrus fruits showed relatively higher values. Our analytical results obtained for the distribution of radiocesium in tea trees show that the root uptake

    To contribute evaluations of dose reduction effect due to evacuation facilities in case of nuclear emergency, we surveyed on structural and material data on 22 facilities (290 rooms) which are listed in local disaster management plan in Matsue city. These facilities can be divided into three categories in terms of structure, scale and intended purpose of them: educational facilities (12 facilities, 235 rooms (include gymnastic hall)), communal facilities (7 facilities, 42 rooms) and gymnastic hall (3 facilities, 13 rooms). Height and floor-area of rooms, as well as window-area were collected as the structural data. We also collected information on constructional materials (i.e. roof, ceiling, inner wall, outer wall, window, floor), and density of those. In addition, mass-thicknesses of the constructional materials were evaluated based on our surveys, and compared to the previous studies which were made in Japan, U.S., and European countries. Consequently, it was found that there is no significant difference of mass-thickness of constructional materials between the results of our surveys and the previous studies. However, for gymnastic hall, since thin metal plates are used for roofs, we can point out that the mass-thickness of roofs are much lower than those for other concrete facilities and clay tile roofing wooden houses.

    The negative impacts of rapid urbanization in developing countries have led to a deterioration in urban air quality, which brings increasing negative impact to its surrounding areas (e.g. in China). However, to date there has been rare quantitative estimation of the urban air pollution to its surrounding areas in China.We thus evaluated the impact of air pollution on the surrounding environment under rapid urbanization in Chinese prefectures during 1999 - 2011. We found that: (1) the urban environment generated increasing negative impact on the surrounding areas, and the PM2.5 concentration difference between urban and rural areas was particularly high in large cities. (2) Nearly half of the Chinese prefectures (156 out of 350) showed increased impact of urban PM2.5 pollution on its surrounding areas. Those prefectures were mainly located along two belts: one from northeast China to Sichuan province, the other from Shanghai to Guangxi province. Our study demonstrates the deterioration in urban air quality and its potential impacts on its surrounding areas in China. We hope that the results presented here will encourage different approaches to urbanization to mitigate the negative impact caused by urban air pollution, both in China and other rapidly developing countries.

    The Monastery of Timios Prodromos is the most important Byzantine monument in the prefecture of Serres and one of the most important monastic foundations of Byzantine times in Northern Greece. It was founded in the late 13th century from Ioannikios and then renovated by his nephew, Joachim. The catholic dates back to the 14th century, and specifically between 1300-1333, under the rule of the second founder Joachim. Considering the pathology of Byzantine mural, for the most effective work on removal of over-paintings layer, fixing, restoration, recovery and maintenance of the painted surface and the substrate, it was decided the sampling from exact points of the mural painting representing the different phases, in order to determine their composition, the technology of construction materials, corrosion mechanisms and the proposal for restoration methodology. The methods to be used require very small quantities of material. The measurements are considered almost non-destructive and based on isotopic geochemistry. The techniques used are X-ray diffraction (XRD), scanning electron microscopy (SEM / EDXA) and isotopic analyzes (d18O and d13C) in a mass spectrometer (IRMS). The study of the samples was carried out by scanning electron microscopy with X-ray microanalyser and analysis of stable isotopes. The study shows that apart from the calcite present in all pigment samples, straw was used as a binder. There is also a mixing of dyes to produce the desired tint while in many cases there are different colour layers. The decay in the mural is extensive, especially in the lower layers of the wall, which have been severely affected by humidity and candle smoke. The creation of gypsum on the surface of the murals is intense and evident in most of the spectra taken

    Slash and burn practices are widely used around the globe with different degrees of success which are mostly related to the impact of fire on the soil properties. In Japan slash and burn practises, known as Yakihata, have a long history and are still used in Yamagata Prefecture today. The purpose of this study was to determine the impact of a low severity controlled fire on Japanese cedar (Cryptomeria japonica) forest soil (Cambisol) which is the dominant species among plantations in Japan. We measured organic carbon and nitrogen content as well as changes in carbon (δ13C) and nitrogen (δ15N) stable isotope composition in a steep west facing slope under heavy precipitation ( 2600 mm/a) and heavy snowfall ( 3-4 m/a). The results show that Ctotal and Ntotal values as well as the isotopes ratios of C and N change with decreasing elevation in the forest as well as in the burned site being consistent with leaching and erosion. The accumulation of Ctotal and Ntotal at the bottom of the slopes was remarkably higher at the slash and burned site than in the control forest site. After slash and burn δ15N isotopes in the slope in general became significantly lighter than in the control forest while the δ13C did not show any significant difference between the two sites except at the bottom of the slopes where δ13C was heavier in the forest. The reason for these changes in nitrogen and carbon isotopes appears to be related to the physical changes in soil horizon sequence of the original forest soil layer. Keywords: high precipitation, Japanese cedar forest soil, low severity fire, stable isotopes, steep slopes

    There have been a number of reports on large outbreaks of hemolytic uremic syndrome (HUS), but there have been no long-term studies of sporadic HUS in Japan. This study therefore investigated the epidemiology and prognosis of HUS in Fukushima Prefecture over a 26 year period. The medical records of 26 patients with HUS between 1987 and 2012 were collected. These children were divided into two groups: those with HUS following an episode of gastroenteritis, often with bloody diarrhea (D + HUS; n = 24) and those with HUS not associated with prodromal diarrhea (D-HUS; n = 2). The D + HUS group was further subdivided into group A (11 patients requiring dialysis) and group B (13 patients not requiring dialysis). The epidemiological and clinical data, as well as prognosis, were retrospectively investigated for each group. Approximately 90% of HUS patients belonged to the D + HUS group. In this group, the mean number of patients per year from 1987 to 1999, and from 2000 to 2012 was 0.92 ± 0.95, and 1.08 ± 0.86, respectively. On admission, lactate dehydrogenase (LDH), alanine aminotransferase (ALT), blood urea nitrogen (BUN), serum creatinine and serum fibrinogen degradation product (FDP) levels in group A were all higher than in group B. Serum albumin level and estimated glomerular filtration rate (eGFR) in group A were lower than in group B. At 6 months after the onset of HUS in the D + HUS group, renal function was normal. The frequency of HUS was constant from 1987 to 2012 in Fukushima. and serum LDH, ALT, BUN, creatinine, and FDP levels as well as eGFR might be risk factors for dialysis in D + HUS children. © 2013 The Authors.

    Full Text Available This study examined the internal Cs exposure of residents and the Cs present in food products produced in Namie. Whole-body counter (WBC was used for the measurement of internal exposure per each whole body of examinees.The food products which appeared to be used for consumption, were brought by residents and commercially available food items were excluded. Most of them were wild plants or food items produced by residents. Four years of data from April 2012 to March 2013 (fiscal 2012 and April 2015 to March 2016 (Fiscal 2015 were analyzed and studied.The average radioactivity measured by WBC was approximately 5 Bq for Cs-134, and 20 Bq for Cs-137 and the average committed effective dose was approximately 1 μSv. The average for the residents with detectable radioactivity was 25 μSv, and the human health effects are considered to be extremely low risk. However, the radioactivity of the affected individuals showed a higher value than the theoretical attenuation rate. The majority (83.2% of individuals exhibiting radioactivity were over 50 years old. The number of food products brought in for detection decreased as the study period progressed, but the number of food products with radioactivity had increased. While the items with a higher detection rate of radioactivity included fruits such as citron and persimmon, shiitake mushrooms exhibited the highest radioactivity. Moreover, the radioactivity of seven items in these 10 items decreased from fiscal 2012 to fiscal 2015. Mushrooms had high radioactivity and were produced over a wide area.We suggest that the elderly try to enjoy life and eat wild plants in moderation while inspecting food products. Therefore, we will continue to work in raising awareness of radiation and its potential presence in food products and thus the continuing necessity of monitoring radioactivity in food in the future.

  6. Nitrate pollution and surface water chemistry in Shimabara, Nagasaki Prefecture, Japan

    Shimabara city has been experiencing serious nitrate pollution in groundwater. To evaluate nitrate pollution and water chemistry in surface water, water samples were collected at 42 sampling points in 15 rivers in Shimabara including a part of Unzen city from January to February 2017. Firstly, spatial distribution of water chemistry was assessed by describing stiff and piper-trilinear diagrams using major ions concentrations. Most of the samples showed Ca-HCO3 or Ca-(NO3+SO4) water types. It corresponds to groundwater chemistry. Some samples were classified into characteristic water types such as Na-Cl, (Na+K)-HCO3, and Ca-Cl. These results indicate sea water mixing and anthropogenic pollution. At the upstream of Nishi-river, although water chemistry showed Ca-HCO3, ions concentrations were higher than that of the other rivers. It indicates that this site was affected by the peripheral anthropogenic activities. Secondly, nitrate-pollution assessment was performed by using NO3-, NO2-, coprostanol (5β(H)-Cholestan-3β-ol), and cholestanol (5α(H)-Cholestan-3β-ol). NO2-N was detected at the 2 sampling points and exceeded drinking standard 0.9 mg L-1 for bottle-fed infants (WHO, 2011). NO3-N + NO2-N concentrations exceeded Japanese drinking standard 10 mg L-1 at 18 sampling points. The highest concentration was 27.5 mg L-1. Higher NO3-N levels were observed in the rivers in the northern parts of the study area. Coprostanol has been used as a fecal contamination indicator, since it can be found in only feces of higher animals. Coprostanol concentrations at 8 sampling points exceeded 700 ng L-1 (Australian drinking water standard). Coprostanol has a potential to distinguish the nitrate pollution sources between chemical fertilizer or livestock wastes, since water samples with similar NO3-N + NO2-N concentration showed distinct coprostanol concentration. The sterols ratio (5β/ (5β+5α)) exceeded 0.5 at 18 sampling points. This reveals that fecal pollution has occurred.

    Truesdell, A.H.; Nakanishi, S.

    2005-01-01

    This investigation has shown that production fluids at Onikobe vary widely in chemical composition and concentration but have certain characteristics in common. These characteristics include a rather narrow range of reservoir temperatures from 230 to 255 deg. C measured temperatures; 225 to 280 deg. C calculated from enthalpy assuming no excess steam; 241 to 270 deg. C calculated from the quartz saturation geothermometer and 253 to 280 deg. C calculated from the most reasonable Na/K geothermometer. The agreement between enthalpy derived and other temperatures suggests that there is little excess steam as does inlet vapour fraction (IVF) values, which are less than 0.1 for almost all samples. The largest variations in concentration are in pH and acid sensitive constituents including Fe, Mg, Ca which are dissolved from reservoir rocks and casings by low pH waters and other constituents with volatility depending on pH (NH 4 , HBO 3 ). The pH varies from 2.8 to 8 and Fe varies from 0.01 to 371 ppm. The variation of other acid sensitive constituents, although not as large, is also significant. The source of the acid is not yet understood. The large 'chloride excess' and the strong correlation of low pH with high chloride indicate that the acid enters the water as HCl, but some SO 4 acidity could have been removed by reaction with plagioclase to form anhydrite. There is a consistent increase in salinity with time along with indications that the waters are gas depleted. These observations are interpreted as showing that injected waters enriched in salts and depleted in gases are contributing to production waters. The acid reservoir seems to be limited to moderate depths in the middle of the drilled area. Drilling either to the NW where wells 134, 135 and 128 (before its casing leak) produced neutral waters or to the S where well 129 produces neutral waters would seem to be the best strategy. The relative homogeneity of the neutral waters suggests that there is a large

B. pumilus inoculation did not enhance growth in any of the plants, although it resulted in a significant increase of (137)Cs concentration and higher (137)Cs transfer from the soil to plants. The Brassica species exhibited different (137)Cs uptake abilities in the order Komatsuna>turnip>mustard>radish. TF values of (137)Cs ranged from 0.018 to 0.069 for all vegetables. Komatsuna possessed the largest root surface area and root volume, and showed a higher (137)Cs concentration in plant tissue and higher (137)Cs TF values (0.060) than the other vegetables. Higher (137)Cs transfer to plants was prominent in soil with a high amount of organic matter and an Al-vermiculite clay mineral type. Copyright © 2015 Elsevier B.V. All rights reserved.

B. pumilus inoculation did not enhance growth in any of the plants, although it resulted in a significant increase of {sup 137}Cs concentration and higher {sup 137}Cs transfer from the soil to plants. The Brassica species exhibited different {sup 137}Cs uptake abilities in the order Komatsuna > turnip > mustard > radish. TF values of {sup 137}Cs ranged from 0.018 to 0.069 for all vegetables. Komatsuna possessed the largest root surface area and root volume, and showed a higher {sup 137}Cs concentration in plant tissue and higher {sup 137}Cs TF values (0.060) than the other vegetables. Higher {sup 137}Cs transfer to plants was prominent in soil with a high amount of organic matter and an Al-vermiculite clay mineral type. - Highlights: • PGPR inoculation did not enhance plant biomass of tested plants. • PGPR inoculation resulted in higher {sup 137}Cs concentration in plants. • Komatsuna that had larger root volume showed higher {sup 137}Cs TF from soil to plants. • Soil with high SOM and Al-vermiculite caused larger {sup 137}Cs transfer to plants.

    Kanagawa Occupational Health Promotion Center conducted a survey on how the MSDS is utilized at workplaces with more than 50 employees handling chemical substances, and what measures are taken to help employees to thoroughly understand information in the Material Safety Data Sheet (MSDS). Questionnaires were sent out to 265 enterprises in Kanagawa prefecture, putting questions to industrial physicians and industrial hygiene supervisors. The objective of the survey was to find out how MSDS is adopted in the system to manage occupational health, what improvements the survey respondents want in MSDS and what expectations the respondents have of our center. 193 enterprises (72.8%) returned answers to the questionnaire. The major findings are as follows. (1) In many companies, information on hazardous/toxic materials is "controlled by a division using such materials", and roughly half of the companies have compiled a common list shared throughout the company. (2) For the most part suppliers submit to the MSDS. Larger companies have a higher rate of posting up or filing the MSDS at their workplaces. Only 25.8% of the companies "rewrite the MSDS so that workers can understand it." (3) Companies that carry out a hazard/toxicity assessment before introducing a new chemical substance account for 72.1%, which is higher than we expected. It indicates that even though the companies don't manage the MSDS adequately, they are highly concerned about hazard control of chemical substances. (4) The rate of answering that "the current MSDS is not easy to understand" is higher among large-sized enterprises and lower among enterprises with fewer than 300 employees. (5) Asked what improvement needs to be made on the MSDS, the industrial physicians and industrial hygiene supervisors gave same answers such as "Workers find the terminology difficult to understand." and "Levels of toxicity can't be clearly identified." (6) The respondents expect our center to provide information for the MSDS

    Full Text Available OBJECTIVE: To describe changes in sexual behaviors among HIV-infected individuals after their HIV diagnosis. METHODS: All HIV-infected individuals diagnosed by the end of 2009 in Taizhou Prefecture were invited to participate in this 12-month prospective study. Assessments including the total number and types of sexual contacts, and condom use details for up to their most familiar eight sexual contacts were collected both at enrollment and 12-month follow-up. RESULTS: 262 HIV-infected individuals were eligible for analysis. The total number of sexual contacts reported by participants was 4,017, 1,496 and 356 during the 12- month period prior to HIV diagnosis (T1, the 12-month period prior to the baseline survey (T2, and the 12-month follow-up period (T3, respectively. The difference in the number of sexual contacts between T2 and T1 was -5 in median (IQR -1, -14, and the difference between T3 and T2 was 0 in median (IQR: 0, -6. A larger proportion of spousal or long-term heterosexual contact was reported from T1(27.7% to T2(42.5% to T3(76.1%, whereas a smaller proportion of commercial heterosexual contacts was reported from T1 (48.6% to T2 (33.2% to T3 (7.0% as well as a smaller proportion of non-commercial casual homosexual contacts was reported from T2 (8.4% to T3 (3.8%.The proportion of consistent condom use increased significantly from T1 (9.3% to T2 (35.3% to T3 (91.5%. CONCLUSION: Sexual behaviors did not change in a uniform manner for the participants in our study. Sexual behaviors and sexual networks vis-à-vis HIV diagnosis and follow-up were associated with the participant's characteristics and HIV infection and treatment status. The overall lesson is that individuals who are unaware of their HIV infection are the main drivers of secondary transmission. Early identification of HIV infection and access to antiretroviral therapy (ART are both key strategies to the control and prevention.

  13. Prolonged Living as a Refugee from the Area Around a Stricken Nuclear Power Plant Increases the Risk of Death.

    Although it is well known that the Great East Japan Earthquake (March 11, 2011) resulted in a large number of disaster-related deaths, it is not common knowledge that the number of disaster-related deaths continues to increase, even four years after the earthquake, in Fukushima Prefecture, where the nuclear power plant accident occurred. There has been a lack of a minute and critical analysis for the causes for this continuous increase. In this report, the causes for the increase in disaster-related deaths in Fukushima Prefecture were analyzed by aggregating and comparing multiple data released by public organizations (the Reconstruction Agency, the National Police Agency, and Fukushima Prefecture), which may also have implications for developing response strategies to other disasters. The disaster-related death rate, the dead or missing rate, and the refugee rate (the number of disaster-related deaths, dead or missing persons, and refugees per 1,000 people) in each prefecture in stricken areas, and also each city, county, town, and village in Fukushima Prefecture, were calculated and compared with each other. The populations which were used for the calculation of each death rate in the area were based on the number of dead victims who had lived in the area when the earthquake occurred, regardless of where they were at the time of their death. The disaster-related death rate was higher than the dead or missing rate in the area around a stricken nuclear power plant in Fukushima Prefecture. These areas coincide exactly with the Areas under Evacuation Orders because of unsafe radiation levels. The external and internal radiation doses of most of the victims of the Great East Japan Earthquake have appeared not to be so high to harm their health, until now. The psychological stress associated with being displaced from one's home for a long time with an uncertain future may be the cause for these disaster-related deaths. There is an urgent need to recognize refugees

    Escherichia coli (E. coli) is one of the most relevant opportunistic pathogenic bacteria as it may cause severe morbidity and mortality in yaks (poephagus grunniens). In recent years, several kinds of antibiotics have been widely used in Tibetan areas to treat the bacterial diseases, resulting in serious repercussions on the bacterial antibiotic resistance in yaks. This investigation was conducted in order to determine the prevalence of antimicrobial resistance and integron gene cassettes in E. coli isolated from yaks in Aba Tibetan Autonomous Prefecture (Aba TAP), China. A total of 278 non-duplicated fresh samples were collected from the yaks in Aba TAP for the isolation and identification of E. coli isolates. Antimicrobial susceptibility testing is performed by using the disc diffusion method according to the Clinical and Laboratory Standards Institute guidelines (CLSI, 2013). Various antibiotic resistance genes and integron gene cassettes were detected by polymerase chain reaction (PCR) and sequencing. Overall, a total of 228 E. coli bacteria were isolated from the fresh faeces of yaks in four different geographical regions. 58% of those isolates showed multi-drug resistance capabilities (MDR) in our study. These isolated bacteria showed a high resistance rate to streptomycin (84%), cefotaxime (79%), amikacin (61%) and trimethoprim-sulfamethoxazole (54%). The most common antimicrobial resistance genes in the isolates were bla CTX-M , sul1, aph (3')-IIa, aac (3)-IIa, aac (6')-Ib, tetB, with respective detection rates of 65%, 46%, 35%, 13%, 11%, and 10%. Furthermore, 66% and 6% of the strains carried Class 1 and 2 integrons, respectively. However, the class 3 integron was not detected. Gene cassette arrays in the class 1 integron included aadA1, aadA7, aadA5, aadA17, dfrA1, dfrA5, dfrA1-aadA1, dfrA12-aadA2 and dfrA17-aadA5. The most prevalent gene cassette was aadA1 (20%). For the class 2 integron, dfrA1-sat2-aadA1 (6%) and dfrA1-sat1-aadA1 (0.4%) were also

    The aim of the study was to evaluate the incidences and obstetric outcomes of women who conceived using assisted reproductive technology (ART) procedures in Fukushima Prefecture before and after the Great East Japan Earthquake and Fukushima nuclear power plant accident. Information was collected and analyzed from 12,070 women who conceived with or without ART in Fukushima Prefecture during the 9 months before and after the disaster. During the 9 months before and after the disaster, 138 (2.0%) and 102 (1.9%) women conceived with in vitro fertilization-embryo transfer (IVF-ET), respectively. The proportion of women who conceived with IVF-ET decreased during the 2 months immediately after the disaster, but returned to pre-disaster levels 3 months after the disaster. In the case of women who conceived without IVF-ET, the incidences of preterm birth and low birth weight increased after the disaster. In contrast, women who conceived with IVF-ET did not differ significantly in obstetric outcomes before and after the disaster but had a higher incidence of cesarean section and low birth weight compared to those conceived without IVF-ET, regardless of the study period. The influence of the disaster on woman who conceived using ART procedures was minimal.

    We investigated the frequencies of 15 autosomal STR loci in the Kazak population of the Ili Kazak Autonomous Prefecture with the aim of expanding the available population information in human genetic databases and for forensic DNA analysis. Genetic polymorphisms of 15 autosomal short tandem repeat (STR) loci were analysed in 456 individuals of the Kazak population from Ili Kazakh Autonomous Prefecture, northwestern China. A total of 173 alleles at 15 autosomal STR loci were found; the allele frequencies ranged from 0.5022-0.0011. The combined power of discrimination and exclusion statistics for the 15 STR loci were 0.999 999 999 85 and 0.999 998 800 65, respectively. In addition, phylogenetic analysis involving the Ili Uygur population and other relevant populations was carried out. A neighbour-joining tree and multidimensional scaling plot were generated based on Nei's standard genetic distance. Results of the population comparison indicated that the Ili Uygur population was most closely related genetically to the Uygur populations from other regions in China. These findings are consistent with the historical and geographic backgrounds of these populations.

    This paper introduces the risk communication activities of the Tokyo Electric Power Company (TEPCO) in Fukushima Prefecture. It analyzed the organizational cause as the background for the Fukushima Daiichi Nuclear Power Station Accident, and concluded that the root cause of the accident is the thought that 'safety has already been secured, and operation rate and the like are important management issues, which incurred the insufficient preparedness for accident.' It has taken six measures as nuclear safety reform plans. One of these is the 'enhancement of risk communication activities.' The nuclear power leader take the initiative to disclose risk under the idea that 'there is no absolute safety (zero risk) in nuclear power,' and promote risk communication for continuously obtaining the understanding of the regional community and society about safety measures, etc. To implement risk communication, 'risk communicators' are installed, and they propose for the management and nuclear leader, about the risk perception and measures associated with public disclosure and its limit, and perform risk communication in accordance with the policy. As the examples of these initiatives, this paper introduces the cases of Fukushima Prefecture, questionnaire study, and evaluations by international organizations. (A.O.)

    The aim of this study was to verify the usefulness for the dose optimisation of setting a diagnostic reference level (DRL) based on the results of a prefecture-wide multi-centre radiation dose survey and providing data feedback. All hospitals/clinics in the authors' prefecture with computed tomography (CT) scanners were requested to report data. The first survey was done in July 2011, and the results of dose-length products (DLPs) for each CT scanner were fed back to all hospitals/clinics, with DRL set from all the data. One year later, a second survey was done in the same manner. The medians of DLP in the upper abdomen, whole body and coronary CT in 2012 were significantly smaller than those of the 2011 survey. The interquartile ranges of DLP in the head, chest, pelvis and coronary CT were also smaller in 2012. Radiation dose survey with data feedback may be helpful for CT dose optimisation. © The Author 2014. Published by Oxford University Press. All rights reserved.

    Telecommunication systems are important for sharing information among health institutions to successfully provide medical response following disasters. The aim of this study was to clarify the problems associated with telecommunication systems in the acute phase of the Great East Japan Earthquake (March 11, 2011). All 72 of the secondary and tertiary emergency hospitals in Miyagi Prefecture were surveyed to evaluate the telecommunication systems in use during the 2011 Great Japan Earthquake, including satellite mobile phones, multi-channel access (MCA) wireless systems, mobile phones, Personal Handy-phone Systems (PHS), fixed-line phones, and the Internet. Hospitals were asked whether the telecommunication systems functioned correctly during the first four days after the earthquake, and, if not, to identify the cause of the malfunction. Each telecommunication system was considered to function correctly if the hospital staff could communicate at least once in every three calls. Valid responses were received from 53 hospitals (73.6%). Satellite mobile phones functioned correctly at the highest proportion of the equipped hospitals, 71.4%, even on Day 0. The MCA wireless system functioned correctly at the second highest proportion of the equipped hospitals. The systems functioned correctly at 72.0% on Day 0 and at 64.0% during Day 1 through Day 3. The main cause of malfunction of the MCA wireless systems was damage to the base station or communication lines (66.7%). Ordinary (personal or general communication systems) mobile phones did not function correctly at any hospital until Day 2, and PHS, fixed-line phones, and the Internet did not function correctly at any area hospitals that were severely damaged by the tsunami. Even in mildly damaged areas, these systems functioned correctly at telecommunications systems do not function.

    To investigate the impact of the Great East Japan Earthquake on preschool children's physical growth in the disaster-affected areas, the three medical universities in Iwate, Miyagi, and Fukushima Prefectures conducted a health examination survey on early childhood physical growth. The survey was conducted over a 3-year period to acquire data on children who were born in different years. Our targets were as follows: 1) children who were born between March 1, 2007 and August 31, 2007 and experienced the disaster at 43-48 months of age, 2) children who were born between March 1, 2009 and August 31, 2009 and experienced the disaster at 19-24 months of age, and 3) children who were born between June 1, 2010 and April 30, 2011 and were under 10 months of age or not born yet when the disaster occurred. We collected their health examination data from local governments in Iwate, Miyagi, and Fukushima Prefectures. We also collected data from Aomori, Akita, and Yamagata Prefectures to use as a control group. The survey items included birth information, anthropometric measurements, and methods of nutrition during infancy. Eighty municipalities from Iwate, Miyagi, and Fukushima Prefectures and 21 from the control prefectures participated in the survey. As a result, we established three retrospective cohorts consisting of 13,886, 15,474, and 32,202 preschool children. The large datasets acquired for the present survey will provide valuable epidemiological evidence that should shed light on preschool children's physical growth in relation to the disaster.

    After the Fukushima Dai-ichi Nuclear Power Plant accident, the Fukushima Health Management Survey (FHMS) was launched. The Basic Survey, a component of FHMS, is a questionnaire used to survey residents across the Fukushima Prefecture about their behaviour in the first 4 months after the accident. The questionnaire findings are used to determine individual external doses by linking behaviour data to a computer programme with daily gamma ray dose rate maps, drawn after the accident. Through 30 June 2015, the response rate was only 27.2% (558 550 population), indicating that the findings might not be generalisable because of poor representativeness of the population. The objective of this study was to clarify if the data from the FHMS Basic Survey were representative of the entire population, by conducting a new survey to compare the external doses between non-respondents and respondents in the previous survey. A total of 5350 subjects were randomly selected from 7 local regions of Fukushima Prefecture. An interview survey was conducted with the non-respondents to the FHMS Basic Survey. A total of 990 responses were obtained from the previous non-responders by interview survey. For the regions Kempoku, Kenchu, Kennan, Aizu, Minami-Aizu, Soso, and Iwaki, differences in mean effective dose (95% confidence interval) in mSv between the non-responders and previous responders were 0.12 (0.01-0.23), -0.09 (-0.21-0.03), -0.06 (-0.18-0.07), 0.05 (-0.04-0.14), 0.01 (-0.01-0.02), 0.09 (0.01-0.17), 0.09 (0.00-0.17), respectively. The differences fall neither within the interval (-∞, -0.25) nor within the interval (0.25, ∞). These findings imply that mean effective doses between the previous and new respondents were not different, with a significantly indifferent region of 0.25 mSv according to equivalence tests. The present study indicates that the dose distribution obtained from about one-quarter of Fukushima residents represents the dose distribution for the entire

    Full Text Available On March 11, 2011, Japan's northeast Pacific coast was hit by a gigantic earthquake and subsequent tsunami. Soma City in Fukushima Prefecture is situated approximately 44 km north of Fukushima Daiichi Nuclear Power Plant. Soma General Hospital is the only hospital in Soma City that provides full-time otolaryngological medical care. We investigated the changes in new patients from one year before to three years after the disaster. We investigated 18,167 new patients treated at our department during the four years from April 1, 2010 to March 31, 2014. Of the new patients, we categorized the diagnoses into Meniere's disease, acute low-tone sensorineural hearing loss, vertigo, sudden deafness, tinnitus, and facial palsy as neuro-otologic symptoms. We also investigated the changes in the numbers of patients whom we examined at that time concerning other otolaryngological disorders, including epistaxis, infectious diseases of the laryngopharynx, and allergic rhinitis. The total number of new patients did not change remarkably on a year-to-year basis. Conversely, cases of vertigo, Meniere's disease, and acute low-tone sensorineural hearing loss increased in number immediately after the disaster, reaching a plateau in the second year and slightly decreasing in the third year. Specifically, 4.8% of patients suffering from these neuro-otologic diseases had complications from depression and other mental diseases. With regard to new patients in our department, there was no apparent increase in the number of patients suffering from diseases other than neuro-otologic diseases, including epistaxis, and allergic rhinitis. Patients suffering from vertigo and/or dizziness increased during the first few years after the disaster. These results are attributed to the continuing stress and tension of the inhabitants. This investigation of those living in the disaster area highlights the need for long-term support.

    In the areas contaminated by radioactive materials due to the Fukushima Daiichi Nuclear Power Station accident, many residents are exposed to radiation through various exposure pathways. Dose assessment is important for providing appropriate protection to the people and clarifying the impact of the accident. The aim of this study is to provide preliminary results of the assessment of radiation doses received by the inhabitants of Fukushima Prefecture. To assess the doses realistically and comprehensively, a probabilistic approach was adopted using data that reflected realistic environmental trends and lifestyle habits in Fukushima Prefecture. In the first year after the contamination, the 95th percentile of the annual effective dose received by the inhabitants evacuated from the evacuation areas and the deliberate evacuation areas was mainly in the 1-10 mSv dose band. However, the 95th percentile of the dose received by some outdoor workers and inhabitants evacuated from highly contaminated areas was in the 10-50 mSv dose band. The doses due to external exposure to deposited radionuclides were the dominant exposure pathway, and their contributions were about 90% under prevailing contamination conditions in Fukushima Prefecture. In addition, 20%-30% of the lifetime effective dose was delivered during the first year after the contamination. (author)

    Ovine sera collected in the Prefectures of Hokkaido, Aomori and Iwate in the Northern Japan were examined for the presence of antibodies against Respiratory syncytial virus (RSV), bovine Herpesvirus type 1 (infectious bovine rhinotracheitis: IBR) and Parainfluenza virus type 3 (PIV3) using serum neutralisation (SN) and enzyme-linked immunosorbent assay (ELISA) tests. Twenty-three animals (11.73%) out of the 196 tested were sero-positive to PIV3. Sixteen animals (8.69%) out of the 184 tested reacted to RSV. No animals were positive to IBR antigen. Sero-conversions to PIV3 were detected in Hokkaido and Iwate (14.92% and 8.82%, respectively). Antibodies against RSV were detected in Hokkaido (9.23%) and Aomori (14.28%). Although no diagnostic measures were in place, the infections did not appear to be related to any reduction in sheep productivity.

    Two independent guidelines on appropriate weight gain for Japanese pregnant women have been established in 1997 and 2006. This study aimed to evaluate changes in the amount of gestational weight gain in pregnant women, the birth weight of their neonates, and the incidence of complications of pregnancy and neonatal outcome in women who delivered at Hyogo Prefectural Kaibara Hospital. Between 1988 and 2014, 6367 women delivered live singleton neonates at full term. The study period was divided into period I (1988-1996), period II (1997-2005), and period III (2006-2014). Changes in weight gain and birth weight were assessed. Complications of pregnancy and neonatal outcome were compared among the periods. Weight gain had been decreased in periods I and II, and weight gain was increased in period III. There was no difference in birth weights between the periods. The incidences of pregnancy-induced hypertension in periods II and III were higher than that in period I (pwomen.

    Full Text Available Ovine sera collected in the Prefectures of Hokkaido, Aomori and Iwate in the Northern Japan were examined for the presence of antibodies against Respiratory syncytial virus (RSV, bovine Herpesvirus type 1 (infectious bovine rhinotracheitis: IBR and Parainfluenza virus type 3 (PIV3 using serum neutralisation (SN and enzyme-linked immunosorbent assay (ELISA tests. Twenty-three animals (11.73% out of the 196 tested were sero-positive to PIV3. Sixteen animals (8.69% out of the 184 tested reacted to RSV. No animals were positive to IBR antigen. Sero-conversions to PIV3 were detected in Hokkaido and Iwate (14.92% and 8.82%, respectively. Antibodies against RSV were detected in Hokkaido (9.23% and Aomori (14.28%. Although no diagnostic measures were in place, the infections did not appear to be related to any reduction in sheep productivity.

    Four novel Lipomyces strains were isolated from soil collected in the Okinawa and Yamanashi prefectures, Japan. Based on their morphological and biochemical characteristics, along with sequence typing using the D1/D2 domain of the LSU rRNA, internal transcribed spacer (ITS) region including 5.8S rRNA, and translation elongation factor 1 alpha gene (EF-1α), the four strains were shown to represent two novel species of the genus Lipomyces, described as Lipomyces okinawensis sp. nov. (type strain No.3-a(35)T=NBRC 110620T=CBS 14747T) and Lipomyces yamanashiensis f.a., sp. nov. (type strain No.313T=NBRC 110621T=CBS 14748T).

    Iodine-131 is one of the most critical radionuclides to be monitored after release from reactor accidents due to the tendency for this nuclide to accumulate in the human thyroid gland. However, there are not enough data related to the reactor accident in Fukushima, Japan to provide regional information on the deposition of this short-lived nuclide (half-life = 8.02 d). In this study we have focused on the long-lived iodine isotope, (129)I (half-life of 1.57 × 10(7) y), and analyzed it by accelerator mass spectrometry (AMS) for surface soil samples collected at various locations in Fukushima Prefecture. In order to obtain information on the (131)I/(129)I ratio released from the accident, we have determined (129)I concentrations in 82 soil samples in which (131)I concentrations were previously determined. There was a strong correlation (R(2) = 0.84) between the two nuclides, suggesting that the (131)I levels in soil samples following the accident can be estimated through the analysis of (129)I. We have also examined the possible influence from (129m)Te on (129)I, and found no significant effect. In order to construct a deposition map of (131)I, we determined the (129)I concentrations (Bq/kg) in 388 soil samples collected from different locations in Fukushima Prefecture and the deposition densities (Bq/m(2)) of (131)I were reconstructed from the results.

    There is a historical group of samurai buildings called the "Preservative District of Johnai Suwakohji Important Traditional Buildings Group" in Kanegasaki Town, Iwate Prefecture. Two woman medical doctors (Misaho Aizawa and Mie Shiga, came from this district at the end of the Meiji Era (1910-1911). Misaho Aizawa was born in a minister's family in 1885 and studied at the Women's School of Dohshisha. After graduation she studied abroad at the Women's Medical College of Philadelphia and graduated from the college in 1910. Immediately after graduation she came back to Japan and got a medical license in Japan. She married a minister and was employed by the Red Cross Clinic in Fukuoka Prefecture. Mie Shiga was born in a samurai-family in 1880 and worked her way through various medical schools in Tokyo. After three failures to pass the national medical examination she received a medical license in 1911. In 1913 she opened her clinic of internal medicine & pediatrics in Utsunomiya. She made an effort to diagnose correctly and won patients' confidence. These two women had neither communication nor common points due to the differences of their family environment and their age. However, they were brought up by fathers who were enthusiastic for education and they made an effort to become woman doctors. Although women's social situation and the female compulsory education rate were low, and women's medical education was poor in the Meiji Era, Misaho Aizawa was able to enter the medical route under the influence of Christianity, and Mie Shiga through the assistance of her family and her samurai spirit.

    Full Text Available The shortage of physicians after a major disaster is a crucial issue. We aimed to evaluate the characteristics of physicians who left affected areas following the accident at Fukushima Daiichi Nuclear Power Plant caused by the Great East Japan Earthquake on March 11, 2011.Using data from a physician census conducted in 2010 (pre-disaster and 2012 (post-disaster, we evaluated changes in the number of physicians in affected areas. We then calculated the odds ratios and 95% confidence intervals using a logistic regression model to evaluate the association between physician characteristics and outflow. We also conducted stratified analyses based on physician characteristics.The number of physicians decreased in Fukushima Prefecture (-5.3% and increased in Miyagi Prefecture (2.8%. The decrease in Fukushima and increase in Miyagi were evident even after taking the prefecture's population change into account (change in physician to population ratios: -1.9% and 3.2%, respectively. Compared with physicians who lived in areas >100 km from the nuclear power plant, physicians living 20-50 km and 50-100 km were, respectively, 3.9 times (95% confidence interval, 2.6-5.7 and 2.6 times (95% confidence interval, 1.7-3.8 more likely to migrate to distant areas. In the stratified analysis, younger physicians and those earlier in their careers had higher odds ratios for outflow than other physicians (P for interaction = 0.02 and <0.01, respectively.The risk of outflow was greater among younger and early-career physicians in areas around the power plant. Political support may be necessary to recruit and retain such physicians, who will be responsible for future community health in the disaster area.

    Teenage motherhood is strongly associated with a range of disadvantages for both the mother and the child. No epidemiological studies have examined related factors for teenage motherhood at both area and individual levels among Japanese women. Therefore, we performed a multilevel analysis of nationwide data in Japan to explore the association of area- and individual-level factors with teenage motherhood. The study population comprised 21,177 mothers living in 47 prefectures who had their first, singleton baby between 10 and 17 January or between 10 and 17 July, 2001. Information on the prefecture in which the mothers resided was linked to prefecture-level variables. Primary outcomes were area-level characteristics (single-mother households, three-generation households, college enrollment, abortions, juvenile crime, and per capita income) and individual-level characteristics, and divided into tertiles or quintiles based on their variable distributions. Multilevel logistic regression analysis was then performed. There were 440 teenage mothers (2.1%) in this study. In addition to individual low level of education [adjusted odds ratio (OR), 7.40; 95% confidence interval (CI), 5.59-9.78], low income [4.23 (2.95-6.08)], and smoking [1.65 (1.31-2.07)], high proportions of single-mother households [1.72 (1.05-2.80)] and three-generation household [1.81 (1.17-2.78)], and per capita income [2.19 (1.06-3.81)] at an area level were positively associated, and high level of college enrollment [0.46 (0.25-0.83)] and lower crime rate [0.62 (0.40-0.98)] at area level were inversely associated with teenage motherhood compared with the corresponding women living in prefectures with the lowest levels of these variables. Our findings suggest that encouraging the completion of higher education and reducing the number of single-mother household at an area level may be important public health strategies to reduce teenage motherhood.

    BABYSCAN, a whole-body counter (WBC) for small children was developed in 2013, and units have been installed at three hospitals in Fukushima Prefecture. Between December, 2013 and March, 2015, 2707 children between the ages of 0 and 11 have been scanned, and none had detectable levels of radioactive cesium. The minimum detectable activities (MDAs) for 137 Cs were ≤3.5 Bq kg -1 for ages 0-1, decreasing to ≤2 Bq kg -1 for ages 10-11. Including the 134 Cs contribution, these translate to a maximum committed effective dose of ∼16 μSv y -1 even for newborn babies, and therefore the internal exposure risks can be considered negligibly small. Analysis of the questionnaire filled out by the parents of the scanned children regarding their families' food and water consumption revealed that the majority of children residing in the town of Miharu regularly consume local or home-grown rice and vegetables, while in Minamisoma, a majority avoid tap water and produce from Fukushima. The data show, however, no correlation between consumption of locally produced food and water and the children's body burdens. (author)

    Based on the electrical logging data of the existed well and Schlumberger sounding data obtained in 1974, a two-dimensional inversion analysis of the specific resistance profile was conducted at the Akinomiya geothermal field, Akita Prefecture. From the electrical logging data, relationships between the geology and the specific resistance were illustrated. The specific resistance values of basement rocks showed more than 100 ohm-m, which were higher than those of the other seams. Intrusive rocks and tuffs in the basement rocks showed locally low values less than 100 ohm-m. Younger volcanic rocks showed low values around 10 ohm-m. As a result of the two-dimensional inversion analysis, the basement rocks could be detected as high specific resistance layers. Accordingly, it was considered that the basement rocks in this field can be detected as high specific resistance layers by analyzing the results of field survey sufficiently. Low specific resistance zones were observed in the shallow depth, which corresponded to the fumarolic gases. There were some layers with remarkably varied specific resistance values, which were considered to be related with alteration. 6 refs., 3 figs.

    Objective: To understand the epidemiological characteristics of newly reported HIV infections in Chinese and Burmese residents during 2012-2016 in Dehong Dai and Jingpo Autonomous Prefecture of Yunnan province (Dehong) and to provide evidence for the development of related programs on prevention and control. Methods: All the HIV infections who were newly reported during 2012-2016 in Dehong, were recruited as the study subjects, with epidemiological characteristics of the cases analyzed by using the software SPSS 22.0. Results: A total of 5 692 HIV infections were newly reported between 2012 and 2016 (including 5 592 in this study), in which the Chinese patients accounted for 43.3 % (2 419) and the rest 56.7 % (3 173) were Burmese. Differences in age, gender and other social characteristics of these newly reported HIV infections were statistically significant between the Chinese and the Burmese (all p -values characteristics of the patients would include: having had primary school education, married, being farmers, and with CD(4)(+)T cells counts ≥350 cells/μl. HIV infection was mainly transmitted through sexual contact among the Chinese patients but through injecting drug use among the Burmese patients. Conclusions: Epidemiological characteristics of the newly reported HIV infections were different between the Chinese and the Burmese, between 2012 and 2016 in Dehong. Targeted prevention and control programs should be taken.

    Full Text Available AIM: To have a detailed picture of school-age children's eyesight status, and the main factors that caused their low vision in Zhouqu County of Gannan Tibetan autonomous prefecture of Gansu province. METHODS: The census work of knowing school-age children's eyesight status was implemented through visual inspection, conventional ophthalmic examination, optometry checks, etc. The results were compared with other domestic epidemiological data. RESULTS: Altogether 536 people with low vision were identified through survey and the rate was 21.12%. Among those people, the number of myopia patients accounted for 80.59% and the prevalence rate was 17.02%. Besides, the prevalence rate of presbyopia was 2.05%, amblyopia 2.76%, strabismus 1.02%, ocular trauma 0.95%, and congenital eye disease 0.71%. CONCLUSION: The prevalence rate of low vision was related with several factors such as gender and nationality. The rate increases with age and the myopia is the primary element that causes low vision.

    Content of 40 elements in plant leaves, soils and rocks collected from several sampling in Okayama Prefecture was analyzed by instrumental neutron activation analysis using the Research Reactor of Kyoto University. Of these, 16 elements were taken up, and the relationship among their amounts in plants, rocks and soils was discussed, focusing mainly on the essential elements of higher plants and related elements in the periodic table. Although most element contents in plant were different among species, the mediam values of the most non-essential elements in the leaf were lower than the contents in the soil and rock samples. However, essential elements showed significantly higher median values than those in the soil and rock samples. Most element contents in leaves showed a logarithmic normal distribution. The normal distribution was observed in most essential elements except for zinc, while non-essential elements did not show a normal distribution. The results obtained by analysis of variance, showed that the plant species studied could be divided into four major groups, namely Dicotyledoneae, Monocotyledoneae, Gymnospermae and Pteridophyta. In general, Dycotyledoneae and Pteridophyta had higher element contents than Monocotyledonaeae and Gymnospermae. (author)

    The aim of this study is to clarify the association between teaching and support skills and the subjective effectiveness of nutritional guidance of registered dietitians working at hospitals. We carried out a questionnaire survey of registered dietitians at hospitals in a Japanese prefecture. The utilization of nutritional teaching skills in nutritional guidance was investigated using a self-produced 36-item questionnaire that was designed to be mainly used for diabetic patients in 4 settings: first guidance, first assessment, contemplation stage, and preparation stage. The support skills were evaluated by Kikuchi's Scale of Social Skills: 18 items. The subjective effectiveness of nutritional guidance was defined by the behavioral change of the patients after nutritional guidance as evaluated by a registered dietitian. There were 75 respondents (response rate 46.6 %). Among the teaching skills, basic skills in an interview were often used, but some related to coaching skills were not in common use in nutritional guidance. Based on the results of principal component analysis, we created a scale for scoring the utilization of nutritional teaching skills in each setting. Multiple linear regression analysis illustrated that high subjective effectiveness of nutritional guidance was associated with high score of teaching skills in the preparation stage setting and high score of support skills. These results show that, in addition to frequent use of nutritional teaching skills, improvement of support skills is also necessary to enhance the effectiveness of nutritional guidance.

    A total of 349 Salmonella enterica subspecies enterica serovar Choleraesuis (S. Choleraesuis) strains, which were isolated between 2008 and 2012 from 349 pigs at two slaughterhouses in Okinawa Prefecture, Japan, were investigated for antimicrobial susceptibility and the presence of antimicrobial resistance genes. All isolates were resistant to at least four antimicrobial agents. The antimicrobial agents for which isolates showed a high incidence of resistance were as follows: ampicillin (100%) and streptomycin (100%), followed by gentamicin (99.7%), oxytetracycline (99.7%), sulfamethoxazole/trimethoprim (99.4%), nalidixic acid (40.1%) and oxolinic acid (40.1%). All isolates were sensitive to cefuroxime, ceftiofur, colistin, fosfomycin, enrofloxacin, orbifloxacin and danofloxacin. The predominant resistance phenotypes and genotypes were: resistance to ampicillin, streptomycin, gentamicin, oxytetracycline and sulfamethoxazole/trimethoprim (58.5%, 204/349) and blaTEM-strA-strB-aadA1-aadA2-aacC2-tet (B)-sul1-sul2-dhfrXII-dhfrXIII (36.1%, 126/349). The quinolone resistance-determining regions (QRDRs) of gyrA, gyrB, parC and parE of the quinolone-resistant isolates (n=12) showed amino acid substitutions of Ser-83→Phe or Asp-87→Tyr in GyrA and Ser-107→Ala in ParC. To our knowledge, this is the first report on the molecular characterization of antimicrobial resistance among S. Choleraesuis strains in Japan.

    This paper statistically analyzed the results of thyroid screening examination of Fukushima 'Citizens' health survey' (full-scale test), which was published by Fukushima Prefecture on June 6, 2016. Standard annual thyroid incidence was set at 5 people in 1 million people at the age between 0 to 19 years based on the announcement of the Japan National Cancer Center (3 people at the prior survey). Increase in the incidence ratio due to false 'screening effect' or 'overdiagnosis' would hardly have happened in the screening of the full-scale test. Districts with significantly higher incidence were So-so district, Nakadori North District (including Fukushima City), Nakadori Central District, Koriyama City, Iwaki City, and Fukushima Prefecture southeast. The comparison chart of age distribution at the time of Chernobyl and Fukushima accidents compiled by Williams (2015) was cited as the evidence that disease cases of thyroid cancer were different between Chernobyl and Fukushima, but this interpretation was wrong. Although increase in childhood thyroid cancer caused by the Chernobyl accident was identified internationally, confirmation has been procrastinating in Fukushima Prefecture. In the future, it should be stressed to grasp the thyroid cancer cases of citizens of 19 years old or older at the time of the accident, cases of other malignant tumors, and cases of non-cancerous diseases.

  6. Statistical Analysis of the Effectiveness of Seawalls and Coastal Forests in Mitigating Tsunami Impacts in Iwate and Miyagi Prefectures.

    Full Text Available The Pacific coast of the Tohoku region of Japan experiences repeated tsunamis, with the most recent events having occurred in 1896, 1933, 1960, and 2011. These events have caused large loss of life and damage throughout the coastal region. There is uncertainty about the degree to which seawalls reduce deaths and building damage during tsunamis in Japan. On the one hand they provide physical protection against tsunamis as long as they are not overtopped and do not fail. On the other hand, the presence of a seawall may induce a false sense of security, encouraging additional development behind the seawall and reducing evacuation rates during an event. We analyze municipality-level and sub-municipality-level data on the impacts of the 1896, 1933, 1960, and 2011 tsunamis, finding that seawalls larger than 5 m in height generally have served a protective role in these past events, reducing both death rates and the damage rates of residential buildings. However, seawalls smaller than 5 m in height appear to have encouraged development in vulnerable areas and exacerbated damage. We also find that the extent of flooding is a critical factor in estimating both death rates and building damage rates, suggesting that additional measures, such as multiple lines of defense and elevating topography, may have significant benefits in reducing the impacts of tsunamis. Moreover, the area of coastal forests was found to be inversely related to death and destruction rates, indicating that forests either mitigated the impacts of these tsunamis, or displaced development that would otherwise have been damaged.

    Various field experiments were carried out using a 1000m deep borehole at Inagawa town, about 10km north of the focus of the Hanshin-Awaji Great Earthquake and directly above the area where shallow earthquake activities have intermittently occurred. These experiments included stress measurement by hydraulic fracturing, hydrophone-aided VSP, permeability tests and observation of various types of logging. The laboratory experiments were also carried out, including measurement of various properties and stresses of the core samples. The stress-depth relationship, determined by the hydraulic fracturing method, shows that the stress gradient well coincides with the Western Japan standard at a depth up to 700m, whereas it is approximately twice as high as the standard at a depth of 946m, at which core disking and borehole break-out are clearly observed, and hence stresses conceivably concentrate locally. Orientation of the maximum horizontal compressive stress is E-W at a depth of around 600m, but greatly changes to NNW-SSE at a deeper position. 4 refs., 5 figs.

    Radioactive Cs ( 134 Cs and 137 Cs) concentrations were measured in various organs and tissues of wild animals (Four species of mammals and 3 species of birds) collected from eastern part of Nihonmatsu City in Fukushima Prefecture, during 2011 to 2013. Muscular concentrations of radioactive Cs were higher than the other organs and tissues such as liver and kidney. However, the tissues which has important role such as brain and reproductive gland showed comparative concentrations of radioactive Cs. Decreasing trends of radioactive Cs in body of wildlife were observed from in April of 2011 to end of 2013. In the other hand, species inhabiting in forest tended to keep relatively high levels of radioactive Cs. Concentrations of radioactive Cs in great cover of birds were higher than those in other parts of feather such as breast feathers. Clearly high concentrations were observed in vane of feather when comparing with those of shaft. These findings suggest that feather samples of birds are effective parts as indicator of exterior pollution of their habitat and also suggest that air pollution of radioactive Cs still continued during on 2012 and 2013. Relative higher concentrations of radioactive Cs were detected in the body of piglets than those of mother of Japanese wild boar and comparative concentrations were observed in the egg albumen and yolk of spot-billed duck.

Therefore, the continual monitoring using wildlife is require strongly for evaluation of ecological risks and human health. (author)

    The aim of this study was to examine whether non-high-density lipoprotein cholesterol (non-HDL-cholesterol) raises the risk of coronary heart disease in a dose-response fashion in a non-obese population with low total cholesterol levels and high HDL-cholesterol levels, such as Japanese. A total of 30,802 men and 60,417 women, aged 40 to 79 years with no history of stroke or coronary heart disease, completed a baseline risk factor survey in 1993 under the auspices of the Ibaraki Prefectural Health Study. Systematic mortality surveillance through 2003 identified 539 coronary heart disease deaths. The mean values for non-HDL-cholesterol were 140 mg/dL for men and 151 mg/dL for women. The corresponding mean values were 193 mg/dL and 208 mg/dL total cholesterol and 52 mg/dL and 57 mg/dL HDL-cholesterol, respectively. Men with non-HDL-cholesterol > or = 180 mg/dL had a two-fold higher age-adjusted risk of mortality from coronary heart disease than did those with non-HDL-cholesterol or = 180 mg/dL versus <100 mg/dL of non-HDL-cholesterol was 2.22 (95% confidence interval: 1.37 to 3.62) for men and 0.71 (0.37 to 1.34) for women. Higher concentrations of non-HDL-cholesterol were associated with an increased risk of mortality from coronary heart disease for men, but not for women.

    Cervical cancer (CC) incidence and mortality among young women have been increasing in Japan. To develop effective measures to combat this, we assessed the feasibility of using a social networking site (SNS) to recruit a representative sample of young women to conduct a knowledge and attitude study about CC prevention via an internet-based questionnaire. From July 2012 to March 2013, advertising banners targeting women aged 16 to 35 years in Kanagawa Prefecture were placed on Facebook in a similar manner as an Australian (AUS) study conducted in 16- to 25-year-olds in 2010 and on a homepage to advertise our CC advocacy activities. Eligible participants were emailed instructions for accessing our secure Web site where they completed an online survey including demographics, awareness, and knowledge of human papillomavirus (HPV) and CC. Data for the study population were compared with the general Japanese population and the AUS study. Among 394 women who expressed interest, 243 (62%) completed the survey, with 52% completing it via Facebook. Women aged 26 to 35 years, living in Yokohama City, with an education beyond high school, were overrepresented. Participants had high awareness and knowledge of HPV and CC, comparable with the AUS study participants. However, the self-reported HPV vaccination rate (22% among participants aged 16-25 years) and the recognition rate of the link between smoking and CC (31%) were significantly lower than in the AUS study (58% and 43%, respectively) (P women into health surveys, which can effectively be performed online. A nationwide survey using SNSs would be an appropriate next step to better understand the current lack of uptake of the national HPV vaccine program by young women in Japan.

    Breast cancer screening by mammography is thought to be effective in reducing breast cancer mortality while ultrasonography is not accepted as a population screening modality, although the latter has been suggested to be useful in detection of cancer in the dense breast, relatively more typical for a younger woman. Mammography with medio-lateral oblique view was offered on trial in 1999-2000 for 3453 female residents in Tochigi prefecture who also underwent clinical breast examination and ultrasonography. The municipalities that provided cancer screening were informed of the final diagnosis for women with positive findings in the screening trial by doctors who performed the diagnostic evaluation. Linkage was also made between the list of participants in the trial and registrations at Tochigi Cancer Registry for breast cancer cases diagnosed during 1999-2001. Thirteen cases with breast cancer were identified during a 2-year follow-up period: 10 were diagnosed subsequent to positive finding in the trial; two were negative in the trial and diagnosed 23 and 24 months after, respectively; and one had a positive finding at the trial but was undiagnosed at first and then diagnosed 18 months after the trial. Among the 11 cases judged as positive in the trial, four were judged only by mammography while three were judged only by ultrasonography. Those mammography alone-detected cases were relatively young, at 36, 40, 47 and 54 years of age, respectively, while the ultrasonography alone-detected cases were aged 50, 55 and 68, respectively. Combined screening with mammography and ultrasonography may be feasible. A larger study is required to evaluate relative performance of mammography and ultrasonography in detail by characteristics of examinees and their breasts. (author)

    The Typhoon No. 18 caused flood on September 15, 2013 in the Kawata River basin, Yoshinogawa City, Tokushima Prefecture. The Kawata River is a raised river bed of 36.7 m with banks to 40.5 m above sea level. The heavy rain did not destroy the banks but made the river level 39.4 m high and then pressed the underflow channel. As the Kawatanaka primary school is located at 36.2 m height, it was not submerged although the underflow channel overbanked the adjacent playground. An educational program on the prevention and reduction for natural disaster, which consists of science, social studies and presentation, was conducted to 18 students of the 4th grade in the period of integrated study in the Kawatanaka primary school from September 17, 2013. On the first day, flow current markings from 625 holes, 30 cm to 1 mm in diameter, on the playground were observed. The flow currents showed direction from SE to NW. On the basis of their observations on the flow currents that water runs from high to low, the students considered the phenomena as a result of tilting of the ground. They conducted activity as their homework to confirm their hypothesis to know if there is any tilt in the ground. They took plastic bottle filled with water and reviled that the ground had 1 to 2 degrees’ tilt to the NW during the experiment. On the bases of the difference between E to W flow of the Kawata River and their SE to NW estimated current flow on the playground and the fact that the bank of the river was not destroyed, the students suggested that the heavy rain had pressed the underflow channels. The suggested channels were found on the playground, where new school buildings were constructed in 2016, by one of the students who studied the program in 2013.

    Described are monitoring systems of water environment at usual times and after the 2011 Tohoku Earthquake and Tsunami Disaster, and measures taken by the Ministry of the Environment (ME) for radioactive substances in the water environment. At usual times, the monitoring of hazardous substance in water environment is conducted by local governments. At/after the Disaster, ME conducted the monitoring investigation concerning the environmental quality standards and toxicants like dioxins in the river, sea and groundwater from late May to late July, 2011 because undesirable effects on health and life of the residents had been feared due to possible leak of hazardous substances in public water area and underground water of victim prefectures, Aomori, Iwate, Miyagi, Fukushima and Ibaraki. As the results, no high contamination due to the Disaster was found, and a part of regions exhibited the slight chemical contamination, where continuous and additional monitoring was to be kept locally with guidance of drinking the concerned well water. ME measured radioactive iodine and cesium at 29 places of Fukushima rivers to find <65 and <30,000 Bq/kg, respectively, of 4 spots of river bed material alone (late May); then Cs 32 Bq/L in water at 1 spot and <26,000 Bq/kg in bed at all places after rain (early July). In groundwater, no radioactive nuclides above were detected in any of 111 places of Fukushima Prefecture (late June to early August). Cs was not found in sea water of 9 places of concerned prefectures, but was in the sea bottom soil, <1,380 Bq/kg (middle June). As well, local governments measured those two radioactive nuclides in water and ambient dose rate of 551 sea bathing beaches (late May to early Oct.) and found only one beach (Iwaki City, Fukushima) inappropriate for swimming play. Hereafter, ME is still to investigate the bed material of public water area and to continue to monitor the marine environment in cooperation with related authorities. (T.T.)

    The tidal volume was estimated for evaluating the effective dose due to radon concentration in the atmosphere. In this study regional population was separated to vocation and non-vocation. The occupancy time and the breathing rate for both vocation and non-vocation groups were estimated, and the annual tidal volume for both groups were calculated. Human actions were separated to 18 activities in the process for estimating the breathing rate. It was clear that the breathing rate depended on human activity and that the human activity changed with its age, so the breathing rate varied with age. Finally the effective doses due to radon and radon progeny indoors and outdoors were evaluated. The maximum annual effective dose was estimated to be 1.2 mSv, minimum 0.2 mSv, and mean 0.51 mSv for vocation. For non-vocation, the male maximum value 0.43 mSv was obtained at the 16 age and the minimum 0.12 mSv at the 70 age, whereas female maximum 0.26 mSv was obtained at the 12 age and the minimum 0.11 mSv at the 70 age. In addition in this study objective areas are Aichi, Gifu, and Mie prefectures for vocation and only Aichi prefecture for non-vocation. (author)

    Mothers of young children are at high-risk for developing adverse mental health effects following a nuclear accident. Using the Japanese pregnancy registration system, the prefecture of Fukushima launched a population-based survey of women who were pregnant at the time of the Fukushima nuclear accident in order to assess their and their newborns' health. In this paper, we focus on the results of a screen for depressive symptoms among new mothers and its association with geographical region and interruption of obstetrical care after the Fukushima nuclear accident, which occurred after the Great East Japan Earthquake on March 11, 2011. The survey targeted women who lived in Fukushima prefecture and who had registered their pregnancies between August 1, 2010 and July 31, 2011. Among the 16,001 women targeted, 9,321 returned the questionnaires (response proportion = 58.3%) and data from 8,196 women with singleton live births were analyzed. The main outcome measure was a standard two-item depression screen. Regional radiation levels were determined from the prefecture's periodical reports, and interruption in obstetrical care after the Fukushima nuclear accident was determined from mothers' individual responses to the questionnaire. Among the 8,196 women, 2,262 (28%) screened positive for depressive symptoms. After adjusting for maternal and infant characteristics, both mothers in Soso, the region in which the nuclear power plant is located, and mothers that had changed obstetrical care facilities were significantly more likely to screen positive for depression. In contrast, mothers in Iwaki and Aizu, regions with relatively low radiation levels, were significantly less likely to screen positive for depression. Our findings suggest that improving mental health support for mothers with infants should be a high priority in the acute phase of nuclear disaster response. We further recommend that in the strategic provisioning of parental support, close attention should

    Speleothem {sup 14}C has recently emerged as a potentially powerful proxy for hydrology changes in comparison with atmospheric {sup 14}C calibration curve, rather than as a direct dating tool, apart from a time marker using bomb peak of {sup 14}C. Some possible causes for the relationship between speleothem {sup 14}C content (or dead carbon fraction: DCF) and karst hydrology have been proposed, such as changes in temperature, precipitation, drip water flow dynamics, cave air ventilation, soil air pCO{sub 2}. In this study, we investigated seasonal variation in {sup 14}C and δ{sup 13}C of drip water in Ryugashi Cave, Shizuoka Prefecture, central Japan, to examine the causes of the {sup 14}C and δ{sup 13}C variations in a speleothem. The results show that different {sup 14}C concentrations and δ{sup 13}C values of drip water from the Ryugashi Cave, were exhibited at different sites of the Caves No. 1, No. 3, and No. 4, which have different temperature, air pCO{sub 2}, and flow paths. Further, the {sup 14}C and δ{sup 13}C of drip waters showed seasonal variations at all sites, which were lower in fall and winter, and higher in spring and summer, though the extent of the variations was different among the sites. The {sup 14}C in drip waters tended to be correlated with the drip rates: {sup 14}C tended to be higher in drip waters with higher drip rates, and also correlated with rainfall amount around the Ryugashi Cave, especially for the drip waters in Cave No. 3, which are considered to have simpler flow paths. The increase in rainfall amount could bring the increase in drip rate of drip water, and then the decrease in interaction between solution and karst, resulting in {sup 14}C increase (DCF decrease) in drip water. Accordingly, the reconstruction of precipitation could be performed using {sup 14}C variation in a speleothem formed by drip water with simple flow dynamics.

    To provide for temporary restrictions of the public water supply system, storage tanks are commonly installed in the domestic water systems of houses and apartment buildings in Okinawa Prefecture of Japan. To learn more about the sanitary condition and management of these water supply facilities with storage tanks (hereafter called "storage tank water systems") and the extent of bacterial contamination of water from these facilities, we investigated their usage and the existence of Aeromonas, enteric and related bacteria. Verbal interviews concerning the use and management of the storage tank water systems were carried out in each randomly sampled household. A total of 54 water samples were collected for bacteriological and physicochemical examinations. Conventional methods were used for total viable count, fecal coliforms, identification of bacteria such as Aeromonas, Enterobacteriaceae and non-fermentative Gram-negative rods (NF-GNR), and measurement of residual chlorine. On Aeromonas species, tests for putative virulence factor and an identification using 16S rRNA and rpoB genes were also performed. Water from the water storage systems was reported to be consumed directly without boiling in 22 of the 54 houses (40.7%). 31 of the sampled houses had installed water storage tanks of more than 1 cubic meter (m 3 ) per inhabitant, and in 21 of the sampled houses, the tank had never been cleaned. In all samples, the total viable count and fecal coliforms did not exceed quality levels prescribed by Japanese waterworks law. Although the quantity of bacteria detected was not high, 23 NF-GNR, 14 Enterobacteriaceae and 5 Aeromonas were isolated in 42.6%, 7.4% and 3.7% of samples respectively. One isolated A. hydrophila and four A. caviae possessed various putative virulence factors, especially A. hydrophila which had diverse putative pathogenic genes such as aer, hlyA, act, alt, ast, ser, and dam. Many bacteria were isolated when the concentration of residual chlorine

    We reported previously that a 10-year community intervention for disability prevention successfully extended healthy life expectancy at 70 years and decreased the enrollment rate of the Long-Term Care Insurance in Kusatsu, Gunma Prefecture, Japan. In order to clarify functional factors that contributed to healthy aging, this study examined changes in physical, nutritional, psychological and social functions in older adults who participated in annual health checkups over the period. Data sources were participants in annual health checkups conducted from 2002 to 2012 and respondents to biannual monitoring surveys conducted from 2003 to 2011. The target population was all older adults aged 70 years and over living in Kusatsu. The average participation rate over the period was 34.7% for the annual health checkups and 95.0% for the monitoring surveys. First, we examined the representativeness of the participants in annual health checkups by comparing them with the responders to monitoring surveys in terms of their higher-level functional capacity, as measured by the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC) (Analysis 1). Second, we examined changes in the physical (4 measures), nutritional (3 measures), and psychological and social (4 measures) functions of participants in annual health checkups over the period. In this analysis, we standardized the data for each year on 11 measures to a mean of 0 and a standard deviation of 1.0 using the 2002 data as the standard, and conducted statistical tests for the slopes of the linear approximate equation (intercept=0) (Analysis 2). In Analysis 1, the TMIG-IC scores for participants in the annual health checkups were significantly higher in both sexes than were those for responders to the monitoring surveys. However, there were no significant year×group interactions in the scores. The difference in scores between the two groups was small for participants in their seventies, but large for

    Paragonimiasis is a typical food-borne parasitic disease, endemic in most parts of Asia, with sporadic case reports from American and African countries. The major source of infection is undercooked freshwater crab or crayfish, though consumption of wild boar meat is also responsible for the infection in Japan, because wild boar is a paratenic host for Paragonimus westermani. Recently, living juveniles of P. westermani were isolated from muscle of a sika deer, Cervus nippon, in Japan, raising the possibility that venison has been another source of infection. In order to clarify the potential contribution of venison consumption to the occurrence of paragonimiasis, we analysed dietary histories of those paragonimiasis patients in whose diagnoses we were involved between 2001 and 2015. Among 380 patients, freshwater crab had been consumed by 208 patients, wild boar meat by 190, and wild deer meat by 76 patients before the onset of the disease. Overall contribution of wild deer meat was estimated to be 6.8% to 20.0%, although in Oita and Gifu Prefectures, where a substantial proportion of patients had consumed raw venison, the contribution of venison consumption was much higher (27.5 to 62.1% and 42.1 to 78.9% in Oita and Gifu Prefectures, respectively). We demonstrated P. westermani-specific antibodies in the sera of 4 out of 160 sika deer from Gifu Prefecture, strongly suggesting that these deer were infected with P. westermani.

    Due to the tragic accident of radioactive contaminant spread from Fukushima Dai-ichi nuclear power plant, the necessity of unmanned systems for radiation monitoring has been increasing. This paper concerns the flight controller design of an unmanned airplane which has been developed for radiation monitoring around the power plant. The flight controller consists of conventional control elements, i.e. Stability/Control Augmentation System (S/CAS) with PI controllers and guidance loops with PID controllers. The gains in these controllers are designed by minimizing appropriately defined cost functions for several possible models and disturbances to produce structured robust flight controllers. (This method is called as 'multiple model approach'.) Control performance of our flight controller was evaluated through flight tests and a primitive flight of radiation monitoring in Namie-machi in Fukushima prefecture was conducted in Jan. 2014. Flight results are included in this paper. (author)

    We evaluate the dependency of damage and restoration of water supply systems and sewerage system on the seismic hazards in the 2011 off the Pacific Coast of Tohoku earthquake focusing on the damage at Ibaraki and Chiba prefectures. We use the damage data of the systems by carrying out field survey, interviews for related local government sectors and surveying the information in web sites. We quantify two damage ratios defined by the ratio of number of physical damage points Np with the related pipeline lengths L and that of disrupted lengths Ld with L. In addition, we discuss relation between restoration periods with the seismic hazards. Finally, we verify the fitting of the damage data with previous seismic fragility curves on sewerage pipelines.

    Most cases of acute gastroenteritis and foodborne disease are not ascertained by public health surveillance because the ill person does not always seek medical care and submit a stool sample for testing, and the laboratory does not always test for or identify the causative organism. We estimated the total burden of acute gastroenteritis in Miyagi Prefecture, Japan, using data from two 2-week cross-sectional, population-based telephone surveys conducted in 2006 and 2007. To estimate the number of acute gastroenteritis illnesses caused by Campylobacter, Salmonella, and Vibrio parahaemolyticus in Miyagi Prefecture, we determined the number of cases for each pathogen from active laboratory-based surveillance during 2005 to 2006 and adjusted for seeking of medical care and submission of stool specimens by using data from the population-based telephone surveys. Monte Carlo simulation was used to incorporate uncertainty. The prevalence of acute gastroenteritis in the preceding 4 weeks was 3.3% (70 of 2,126) and 3.5% (74 of 2,121) in the winter and summer months, yielding an estimated 44,200 episodes of acute gastroenteritis each year in this region. Among people with acute gastroenteritis, the physician consultation rate was 32.0%, and 10.9% of persons who sought care submitted a stool sample. The estimated numbers of Campylobacter-, Salmonella-, and V. parahaemolyticus -associated episodes of acute gastroenteritis were 1,512, 209, and 100 per 100,000 population per year, respectively, in this region. These estimates are significantly higher than the number of reported cases in surveillance in this region. Cases ascertained from active surveillance were also underrepresented in the present passive surveillance, suggesting that complementary surveillance systems, such as laboratory-based active surveillance in sentinel sites, are needed to monitor food safety in Japan.

    Tokyo Metropolitan area (i.e. southern part of Kanto district) is known for one of the hottest areas in summer in Japan. Especially in Saitama prefecture (north of Tokyo), the daily maximum surface air temperature (SAT) at screen height sometimes reached in 40 C. In the last decade, the summer heat environment in Japan is getting worse, and the number of emergency transportations due to heat stroke is rapidly increasing. In this study, we evaluate regional climate change due to some factors, such as land use / land cover changes. To evaluate the regional climate change, we performed analysis of observed data and a series of past climate simulations using the Weather Research and Forecasting (WRF) model with high horizontal resolution, including an urban canopy sub-model.

    Iodine intake by adults in farming districts in Northeastern Japan was evaluated by two methods: (1) government-approved food composition tables based calculation and (2) instrumental measurement. The correlation between these two values and a regression model for the calibration of calculated values was presented. Iodine intake was calculated, using the values in the Japan Standard Tables of Food Composition (FCT), through the analysis of duplicate samples of complete 24-h food consumption for 90 adult subjects. In cases where the value for iodine content was not available in the FCT, it was assumed to be zero for that food item (calculated values). Iodine content was also measured by ICP-MS (measured values). Calculated and measured values rendered geometric means (GM) of 336 and 279 μg/day, respectively. There was no statistically significant (p > 0.05) difference between calculated and measured values. The correlation coefficient was 0.646 (p value from calculated value. A survey of the literature suggests that the values in this study were similar to values that have been reported to date for Japan, and higher than those for other countries in Asia. Iodine intake of Japanese adults was 336 μg/day (GM, calculated) and 279 μg/day (GM, measured). Both values correlated so well, with a correlation coefficient of 0.646, that a regression model (Y = 130.8 + 1.9479X, where X and Y are measured and calculated values, respectively) could be used to calibrate calculated values.

    perception as a result of its interrelationships between motion, gaze, and sound. This paper uses four films, one of which is a drone flyover, to launch a discussion concerning a smooth and alluring gaze, a sliding gaze that penetrates landscapes, and site appearance. Films hold the capacity to project both...... a site and near-sensory experience. In so doing, films can achieve an intimate reflection of both outer experience and affection of inner sensations, and the audio-visual and time-space based presentation of this dualism can mimic human experience. This paper discusses how this embedded transference...... and transcendence can facilitate a deeper understanding of intimate sensations, substantiating their role in the future design and planning of urban landscapes. Hence, it addresses the ethics of an intimacy perspective (of drone filming) in the qualification of quiet areas....

    In the spring of 2015, we experienced a cluster of 4 sporadic cases of yersiniosis in children in Nagano prefecture, a rural area of Japan. Two patients developed appendicitis-like episodes; one had acute gastroenteritis, and the other had bacteremia associated with liver abscess. The causative agent of these infections was Yersinia enterocolitica serogroup O:8. None of the patients had an underlying illness, and all have recovered completely. The patients were neither socially nor geographically related to each other. These 4 consecutive cases suggest that Y. enterocolitica O:8 has spread substantially in the middle part of Japan, and that this virulent strain might be more common than previously reported in our country.

    Several studies have reported on increases in the incidence of cardiovascular and cerebrovascular diseases after huge earthquakes. An increase in the incidence of cerebrovascular diseases was observed after the Great East Japan Earthquake and Tsunami of 2011. To assess whether tsunami damage or the earthquake was responsible for this trend, we assessed the relative impact of earthquake magnitude and flood damage on cerebrovascular disease. A total of 12 coastal municipalities facing the epicenter were divided into 4 flood severity groups according to the percentage of people living in the flooded areas (earthquake severity group. Odds ratios (ORs) of disease incidence and the adjusted ORs for seismic intensity (using the Mantel-Haenszel method) between the higher (≥40%) and the lower flooded area (Earthquake and Tsunami of 2011 increased because of tsunami damage and not because of the earthquake magnitude. © 2014 S.

    Full Text Available Abstract Background Since Fuchs' report in 1999, the reported protective effect of dietary fiber from colorectal carcinogenesis has led many researchers to question its real benefit. The aim of this study is to evaluate the association between diet, especially dietary fiber and fat and colorectal cancer in Japan. Methods A multiple regression analysis (using the stepwise variable selection method was performed using the standardized mortality ratios (SMRs of colon and rectal cancer in 23 Japanese prefectures as objective variables and dietary fiber, nutrients and food groups as explanatory variables. Results As for colon cancer, the standardized partial correlation coefficients were positively significant for fat (1,13, P = 0.000, seaweeds (0.41, P = 0.026 and beans (0.45, P = 0.017 and were negatively significant for vitamin A (-0.63, P = 0.003, vitamin C (-0.42, P = 0.019 and yellow-green vegetables (-0.37, P = 0.046. For rectal cancer, the standardized partial correlation coefficient in fat (0.60, P = 0.002 was positively significant. Dietary fiber was not found to have a significant relationship with either colon or rectal cancers. Conclusions This study failed to show any protective effect of dietary fiber in subjects with a low fat intake (Japanese in this analysis, which supports Fuchs' findings in subjects with a high fat intake (US Americans.

    This study aimed to clarify the management of emergency electric power and the operation of radiology diagnostic devices after the Great East Japan Earthquake. Timing of electricity restoration, actual emergency electric power generation, and whether radiology diagnostic devices were operational and the reason if not were investigated through a questionnaire submitted to all 14 disaster base hospitals in Miyagi Prefecture in February and March 2013. Commercial electricity supply resumed within 3 days after the earthquake at 13 of 14 hospitals. Actual emergency electric power generation was lower than pre-disaster estimates at most of the hospitals. Only 4 of 11 hospitals were able to generate 60% of the power normally consumed. Under emergency electric power, conventional X-ray and computed tomography (CT) scanners worked in 9 of 14 (64%) and 8 of 14 (57%) hospitals, respectively. The main reason conventional X-ray and CT scanners did not operate was that hospitals had not planned to use these devices under emergency electric power. Only 2 of the 14 hospitals had a pre-disaster plan to allocate emergency electric power, and all devices operated at these 2 hospitals. Pre-disaster plans to allocate emergency electric power are required for disaster base hospitals to effectively operate radiology diagnostic devices after a disaster.

    An outbreak of enterohaemorrhagic Escherichia coli O157 occurred in multiple prefectures of Japan in November 2009. We conducted two case-control studies with trace-back and trace-forward investigations to determine the source. The case definition was met by 21 individuals; 14 (66.7%) were hospitalised, but no haemolytic uraemic syndrome, acute encephalopathy or deaths occurred. Median age was 23 (range 12-48) years and 14 cases were male (66.7%). No significant associations with food were found in a case-control study by local public health centres, but our matched case-control study using Internet surveys found that beef hanging tender (or hanger steak), derived from the diaphragm of the cattle, was significantly associated with illness (odds ratio = 15.77; 95% confidence interval, 2.00-124.11). Pulsed-field gel electrophoresis analysis of isolates from patients and the suspected food showed five different patterns: two in faecal and food samples, and another three in patient faecal samples only, although there were epidemiological links to the meat consumed at the restaurants. Trace-back investigation implicated a common food processing company from outside Japan. Examination of the logistics of the meat processing company suggested that contamination did not occur in Japan. We concluded that the source of the outbreak was imported hanging tender. This investigation revealed that Internet surveys could be useful for outbreak investigations.

    In September 2012, several cows and a calf showed decreased activity, anorexia and fever on Ishigaki Island, Okinawa Prefecture, Japan, and the cases were diagnosed as bovine ephemeral fever (BEF). We isolated BEF virus (BEFV) from one of the affected cows and then determined the complete genome sequence of the G gene, which encodes a class I transmembrane glycoprotein of BEFV. The BEFV isolate in this case, ON-3/E/12, was sorted into the same cluster as other BEFV isolates in Japan, Taiwan and China obtained in 1996-2004 and was most closely related to a 2002 Chinese isolate, JT02L, according to the phylogenetic analysis of the complete G gene. Since inactivated vaccines for BEF available in Japan are considered effective against the ON-3/E/12 isolate as well as other isolates in East Asia from 1996-2004, annual vaccination should be conducted to prevent BEF in Okinawa. Additionally, in this study, we developed an RT-PCR assay to detect the BEFV gene in Japan and neighboring countries. Our assay was able to amplify target sequences in all of the tested BEFV isolates, including 18 isolates in Japan and another isolate in Australia. The assay was found to be useful also for testing RNA samples extracted from bovine peripheral blood mononuclear cells, and the detection limit of the assay was 10 copies per tube. We believe that our assay would be an important tool for the screening of BEFV infection and the diagnosis of BEF.

    Consciousness for the earthquake was investigated by questionnaire surveys made in Honjo City and Yuzawa City, Akita Pref. in October 1995 twelve years after the Nihonkai Chubu Earthquake (M=7.7) in May 1983. The survey was conducted in terms of 27 items including personality, memory, knowledge/interest, psychology/action, mental attitude/preparations, wishes for researchers and administration, etc. Also included were the items on the Great Hanshin-Awaji Earthquake and the earthquake blank areas. The number of distributed questionnaires and the recovery rate of them are 1500 and 79.2% in Honjo City, and 1700 and 84.7% in Yuzawa City. From the survey, it was found that people have a lot of knowledge of and high interest in the earthquake and well remember it, and a lot of people know of tsunami, liquefaction phenomena, and the earthquake blank area. Further, they are afraid of earthquakes and think of their actions to be taken in case of earthquake. However, most people are little prepared for earthquakes. Important future subjects were suggested for the study of disaster prevention measures. 13 figs.

    Noto Peninsula earthquake occurred in Ishikawa Pref., in March, 2007, and the Noto Yuryo, and many arterial roads were damaged. This led to the conosiderable confusion of the road traffic in Noto Peninsula area and gave the influence on all kinds of social/economic activities. Therefore, an method of providing the traffic information for drivers is important in the case of disasters such as earthquakes. We carried out a questionnaire survey for local inhabitants and investigated the road use situation at the time of the Noto Peninsula earthquake and the information acquisition situation about it. We also analyzed whether or not the method of providing the traffic information was appropriate. In addition, we examined the best traffic information in the case of earthquakes.

    Full Text Available Abstract Background Although economic reforms have brought significant benefits, including improved health care to many Chinese people, accessibility to improved care has not been distributed evenly throughout Chinese society. Also, the effects of the uneven distribution of improved healthcare are not clearly understood. Evidence suggests that mortality is an indicator for evaluating accessibility to improved health care services. We constructed spatially smoothed risk maps for gender-specific adult mortality in an area of southern China comprising both urban and rural areas and identified ecological factors of gender-specific mortality across societies. Results The study analyzed the data of the Hechi Prefecture in southern in China. An average of 124,204 people lived in the area during the study period (2002–2004. Individual level data for 2002–2004 were grouped using identical rectangular cells (regular lattice of 0.25 km2. Poisson regression was fitted to the group level data to identify gender-specific ecological factors of adult (ages 15– Conclusion We found a disparity in mortality rates between rural and urban areas in the study area in southern China, especially for adult men. There were also differences in mortality rates between poorer and wealthy populations in both rural and urban areas, which may in part reflect differences in health care quality. Spatial influences upon adult male versus adult female mortality difference underscore the need for more research on gender-related influences on adult mortality in China.

    The current geoscientific research of the Mizunami Underground Research (MIU) Project have been carried out since the 1996 fiscal year at the Shobasama site in Akeyo-cho, Mizunami City, Gifu Prefecture. The main goals of the MIU Project are to establish comprehensive techniques for investigating the geological environment, to acquire data on the deep geological environment and to develop a range of engineering techniques for deep underground application in granite. Data flow diagrams of the surface-based investigations were drawn up based on the results of the surface-based investigations since the 1996 fiscal year. Comparisons of the results among seismic reflection survey, borehole investigation (core observation, geophysical logging) and vertical seismic profile were carried out. Hydrogeological modeling and groundwater flow analyses were performed taking account of faults (including Tsukiyoshi fault) that were estimated by lineament distributions in the study area (about 4x6 km). High-quality information on geology, hydrogeology and hydrochemistry of the sedimentary formations and the Toki granite are being acquired in the MIU-4 investigations. The rock mechanical model was revised on the results of MIU-1, 2 and 3 borehole investigations. The preliminary analyses were performed to understand the behavior of deformation caused by the construction of shafts. (author)

    We evaluated the stored body fat of Japanese black bears (Ursus thibetanus japonicus) killed as nuisances in Gifu and Fukushima prefectures, Japan, during 2005-2007. We employed femur marrow fat (FMF), modified kidney fat index (mKFI), and abdominal subcutaneous fat (ASF) as indices for quantitative evaluation. We examined the basic characteristics of these indices, such as seasonality, age and sex dependency, and the quantitative relationship among them. mKFI and ASF increased towards the beginning of the denning period (December), while FMF was relatively stable throughout the sampling period (July-December). In cubs, all indices showed significantly lower values than in the older age classes. There seemed to be a catabolizing order between FMF and mKFI, but not between mKFI and ASF. We also evaluated the yearly change in the indices, and discussed its relevance to the incidence of bear intrusion into human residential areas. Bears nuisance-killed in summer (July-September) 2006 had a significantly larger amount of stored body fat than those killed in summer 2007, although the number of nuisance kills was larger in 2006 than in 2007. This suggests that poor nutritional condition is not a direct cause of bear intrusion.

    The purpose of this study was to clarify the occurrence rate and characteristics of spinal injuries caused by snowboarding that were sustained at the Okumino skiing area in Gifu Prefecture, Japan, from 1988 to 2000. This study was a retrospective review of 13,490 cases of snowboard- or ski-related injury treated at Sumi Memorial Hospital over this period. A total of 7,188 patients sustained snowboard-related injuries, and 238 of these had spinal injuries caused by snowboarding (3.3%), whereas 6,302 patients sustained ski-related injuries, and 86 of these had spinal injuries caused by skiing (1.4%). Although there were no significant differences in the difficulty of slope, location of vertebral fracture, or spinal cord injury between snowboarders and skiers, the incidence of transverse process fractures was significantly higher in snowboard-related than in skiing-related injury (p jumping than beginners (p skiing resulted from a simple fall. Spinal injuries sustained while snowboarding are increasing considerably in incidence and are characterized as complex injuries. We must educate young snowboarders of the risk of this sport, to prevent these serious injuries.

    The current geoscientific research of the Mizunami Underground Research Laboratory (MIU) Project have been carried out since the 1996 fiscal year at the Shobasama site in Akeyo-cho, Mizunami City, Gifu Prefecture. The main goals of the MIU Project are to establish appropriate methodologies for reliably investigating and assessing the deep subsurface, and to develop a range of engineering techniques for deep underground application in granite. The site for MIU construction was changed in January 2002, from the Shobasama site to city-owned land (MIU facility site) after lease contract with Mizunami city. The surface-based investigations at the MIU facility site have started since February 2002. The conceptual modeling work around the MIU facility site has started based on the information from the previous investigations of the Regional Hydrogeological Study and MIU project. Based on the conceptual model, the planning of geophysical survey and shallow borehole investigations has started. These investigations will be done in 2002 fiscal year. Hydrogeological modeling and groundwater flow analysis were performed in the study area (about 4 x 6 km around the Shobasama site). The preliminary analysis based on the rock mechanical model at the Shobasama site was performed to understand the behavior of deformation caused by the construction of shafts. (author)

    Full Text Available The VHF electromagnetic noise intensity data at several stations in the Tohoku area of Japan during the period of a rather large (with magnitude of 7.2 earthquake (Miyagi-ken oki earthquake taken place on 16 August 2005, are analyzed by means of different fractal analysis methods, including (1 spectral slope estimation, (2 multi-fractal detrended fluctuation analysis and (3 multi-fractal wavelet transform modulus maxima method. It seems to the authors that there is no definite analysis method for the analysis of any seismogenic phenomenon, so that the only way we have to take, is to apply different methods to the same data for the detailed comparison of the results. This comparison enables us to deduce the properties commonly observed by the above methods. Because the most important feature common to these three methods, is that significant changes in fractal scaling characteristics are observed just during the earthquake (mainly before the earthquake only at one station of Kunimi. Finally, we can come to the definite conclusion on the self-organization of VHF emissions only at one station in the present case.

    Boundary effect analysis is related to border policy making in the cross-border ethnic area. The border effect literatures show that geographic boundaries have obvious impacts on economic, social and cultural relations in both sides of a nation border. Particularly in cross-border ethnic areas, each ethnic group has strong internal spatial structure relevance, and the boundary effect is more obvious. However, most of China's border areas are cross-border ethnic areas, each of border issues is unique. Under this perspective, we analyze the border effects of various boundaries can provide basis for formulating border management policies. For small scale of cross-border ethnic minority areas, how to formulate the boundary management policy is a good question to explore. This paper is demonstrated by a study of the impact of border management policies in Dehong Dai and Jingpo Autonomous Prefecture in Yunnan Province at the border area to Burma. The comparative method is used to analysis the border management policies in past 50 decades for the border area of Yunnan Province .This research aims to define trends within border policy and its influences to national security. This paper also examines Wendy Brown's liberal theory of border management policy. We found that it is not suitable for Sino-Burma border area. The conclusion is that the changes or instability of international economic and political situation has more influence to this cross-border ethnic area, and only innovative policy will be effective in cross-border ethnic area. So the border management policies should reflect the change of international context.

    To investigate riverine transfers from contaminated soils of the Fukushima Prefecture in Japan to the marine environment, suspended sediments, filtered water, sediments and detrital organic macro debris deposited onto river beds were collected in November 2013 within small coastal rivers during conditions of low flow rates and low turbidity. River waters were directly filtered on the field and high efficiency well-type Ge detectors were used to analyse radiocaesium concentrations in very small quantities of suspended particles and filtered water (a few mg to a few g). For such base-flow conditions, our results show that the watersheds studied present similar hydro-sedimentary behaviours at their outlets and that the exports of dissolved and particulate radiocaesium are comparable. Moreover, the contribution of these rivers to the instantaneous export of radiocaesium to the ocean is similar to that of the Abukuma River. Our preliminary results indicate that, in the estuaries, radiocaesium concentrations in suspended sediments would be reduced by more than 80%, while radiocaesium concentration in filtered waters would be maintained. Significant correlations between radiocaesium concentrations and radiocaesium inventories in the soils of the catchments indicate that there was at that time little intra and inter-watershed variability in the transfer processes of radiocaesium from lands to rivers at this regional scale. The apparent liquid–solid partition coefficient (K D ) values acquired for the lowest loads/finest particles complement the values acquired by using sediment traps and highlight the strong capacity of the smallest particles to transfer radiocaesium. Finally, but not least, our observations suggest that there could be a significant transfer of highly contaminated detrital biomass from forest litter to the downstream rivers in a rather conservative way. - Highlights: • Radiocesium concentrations were assessed by using high performance well-type Ge

    With a focus on the efforts of the Atomic Energy Society of Japan for the accident of TEPCO Fukushima Daiichi Nuclear Power Station, this paper introduces the movement of decommissioning and decontamination, as well as the efforts for regional revitalization. After the accident, the Atomic Energy Society of Japan performed information collection / analysis / evaluation, held a variety of symposiums, listened to the opinions of experts and knowledgeable persons in and out of Japan, discussed the measures for the accident, and expressed its opinions. The investigation committee academically summarized a wide variety of information about the accident, and published a report. In its accident investigation report, it analyzed the underlying factors of the accident, and proposed recommendations of 50 items. It has continued for an additional contribution to complete the decommissioning project. It is disseminating accurate and easy-to-understand information as the standpoints of residents as well as a nuclear expert. It dispatches specialists to 'Decontamination Information Plaza' to continuously carry out the decontamination advisory job. As part of regional revitalization, it has been implementing a support, such as the provision of counselling and accurate information for the decision-making on the returning-home of refugees. Its contents are as follows; (1) provision of information on the decontamination situation of each site, (2) consultation about the health effects of radiation, and (3) dispatch cooperation of lecturers for education of the staff of municipalities.

    1977-01-01

    The Law envisages to promote the arrangement of public facilities in the sorrounding areas of power generating facilities to help to smooth the establishment of power generating facilities by increasing the welfare of inhabitants. The power generating facilities include those of atomic energy, hydrauric and steam power, the reprocessing facilities for nuclear fuel materials for atomic power generation and other facilities closely related to such power generation. The competent minister (Prime Minister, Minister of International Trade and Industry and other Ministers concerned) designates and makes public the following locations among the locations where power generating facilities are expected to be set up, namely, a location where the establishment plan seems sure, a location that is not included in the removal promoting areas provided for by the Law for Promotion of Industry Redistribution, a location where the arrangement of public facilities seems necessary for the smooth establishment of such facilities, etc. The governor of each prefecture may prepare the arrangement plan of public facilities including roads, harbors, waterworks, etc. in the sorrounding areas of the locations designated, and file the applications for permission of the plan to the competent minister. The government may grant subsidy to the local municipalities for the expenses of the undertakings based on the arrangement plan. When necessary, the government may also transfer some ordinary assets of the nation to the local municipalities which bear the expenses of such undertakings. (Okada, K.)

    The intensities of seismic waves observed at the dense seismic array of the Tokyo Metropolitan Seismic Observation network (MeSO-net) inside the Kanto basin, display unusual distribution patterns. In several occasions, the highest intensities are not observed in the area above an earthquakes hypocenter but appear sifted more than 20 km away. In order to understand the source of this unusual intensity distribution pattern, it is crucial to understand how the waves attenuate before they reach the surface. The attenuation of seismic waves along their path is represented by the t∗ attenuation operator that can be obtained by fitting the observed seismic wave spectrum to a theoretical spectrum using an ω2 model. In order to create a high quality dataset, only 1449 earthquakes that are recorded with intensity greater than 0 in the Japan Meteorological Agency (JMA) intensity scale are selected from the JMA unified earthquake list from April 1st 2008 to October 2nd 2013. A grid search method is applied to determine the t∗ values by matching the observed and theoretical spectra. The t∗ data where then inverted to estimate a 3D Q structure with grid points set at a 10 km spacing. We implemented the 3D velocity model estimated by Nakagawa et al., 2012 and in addition we set the initial Q values at 100 for the 0 km grids and to 400 for the grids below them. The obtained model suggests average Q values of 50˜100 inside the Kanto basin. Furthermore, a low Q zone is observed in the area where the Philippine Sea plate meets the upper part of the Pacific sea plate. This area is located at approximately 40 km depth, beneath the north-east Tokyo and west Chiba prefectures and is represented by Q values Earthquakes occurring on the Pacific plate pass through this low Q area inside the Philippine sea plate and are attenuated significantly. The estimated attenuation distribution at the MeSO-net station for these earthquakes implementing our 3D Q model greatly coincides with the

    This study investigated the cause of radial fruit cracking in tomato cultivation under rain shelter in the cool uplands in Gifu Prefecture. The effect of total integrated radiation using two types of training methods was determined over a three-year period. The percentage of refused radial fruit cracking associated with increased total integrated solar radiation from the young fruit stage to the mature green stage. Fruit cracking occurred in the training method which foliage and fruits received a large amount of light-interception. Also, as for fruits that undergo vigorous enlargement, the frequency of the radial fruit cracking increased

    This article describes regional differences in the homicide patterns which occurred in Sapporo City and the surrounding area, and in Akita, Ibaraki, Chiba and Toyama prefectures in Japan. Information collected from each case of homicide included factors such as age, sex of the victim and assailant, causes of death, disposition of the offender, relationship between assailant and victim, reasons for criminal action, et al. The statistical features of homicidal episodes among the five different regions showed considerable variation, as follows. The mean death rates for homicide (number of victims per 100,000 of population) during the period 1986-1995 were 0.44 (Sapporo), 0.8 (Akita), 0.58 (Toyama), 0.7 (Ibaraki) and 0.75 (Chiba), respectively. Close family relationship between the victim and assailant was observed in the homicidal acts which occurred in Sapporo, Akita and Toyama. Assailant's relationship to victim was commonly extra-familial in Ibaraki and Chiba-neighboring megalopolis Tokyo, where some events of murder by a foreigner occurred. Homicide by female assailant, murder by mentally abnormal killers and homicide-suicide events were closely associated with family members. And these factors contributed to the considerable number of victims in Sapporo, Akita and Toyama. But, this close family relationship of the victim to the assailant did not correspond with the elevation in the number of deaths, and it was rather inversely related to the higher death rates recognized in Ibaraki and Chiba. This comparative study suggested that rapid urbanization considerably affects regional differences in homicide patterns.

    Vulnerability assessment to delineate areas that are more susceptible to contamination from anthropogenic sources has become an important element for sensible resource management and landuse planning. This contribution aims at estimating aquifer vulnerability by applying the RISKE model in Banyas Catchment Area (BCA), Tartous Prefecture, west Syria. An additional objective is to demonstrate the combined use of the RISKE model and a geographical information system (GIS) as an effective method for groundwater pollution risk assessment. The RISKE model uses five environmental parameters (Rock of aquifer media, Infiltration, Soil media, Karst, and Epikarst) to characterize the hydro-geological setting and evaluate aquifer vulnerability. The elevated eastern and low western part of the study area was dominated by high vulnerability classes, while the middle part was characterized by moderate vulnerability classes. Based on the vulnerability analysis, it was found that 2% and 39% of BCA is under low and high vulnerability to groundwater contamination, respectively, while more than 52% and 5% of the area of BCA can be designated as an area of moderate and very high vulnerability to groundwater contamination, respectively. The GIS technique has provided an efficient environment for analyses and high capabilities of handling a large amount of spatial data. Copyright 2009 Elsevier Ltd. All rights reserved.

    [Purpose] To clarify seasonal changes in activity levels among nursing care insurance service users in areas with different climates using the Life Space Assessment. [Subjects] A total of 72 nursing care insurance service users aged ≥65 years, who were from areas along the Sea of Japan or those around the Inland Sea. [Methods] The subjects were divided into 2 groups according to their home prefecture, and each survey was conducted over two successive seasons (Survey I: fall and winter, n=48, Survey II: winter and spring, n=24). We investigated the subjects' basic information, and determined their FIM, the Life Space Assessment, and Modified Falls Efficacy Scale scores. These scores were subjected to between-group and -season comparisons. [Results] In Survey I, there were no significant differences in any investigation item between the 2 groups, but the Japan Sea group showed decreases in the Life Space Assessment, Independent Life space, and Minimal Life space scores in winter. In Survey II, we did not note any between-group or -season differences. [Conclusion] Our findings suggest that the Life Space Assessment, whose scores are influenced by outdoor environments, may be used as a tool to clarify seasonal changes in activity levels of nursing care insurance service users.

    One of the major concerns for the high-level radioactive waste disposal is the possibility of the radionuclides to reach biosphere by groundwater flow. Recent research results have shown that the fresh groundwater discharge from subsea formations are widespread phenomena, thus, it is necessary to evaluate the submarine groundwater discharge as possible pathways of contaminant discharge towards the biosphere. It is also important to unravel the groundwater flow and associated material transport at the coastal area and subsea formations. To better understand the groundwater flow processes and the submarine groundwater discharge, we have conducted the hydrological, hydrogeological, geochemical, and numerical modeling studies at the Kurobe alluvial fan and its offshore, Toyama Prefecture, Japan. In this report, the results of the following research activities are presented: 1) Development and application of a method to detect the locations of the submarine groundwater discharge. 2) Development and application of a method to collect uncontaminated groundwater samples from subsea formations. 3) Measurements of submarine groundwater discharge fluxes by automated seepage meter. 4) Hydrological and geochemical studies for groundwater flow at the coastal area. 5) Geochemical studies to understand sources of fresh submarine groundwater discharge. 6) Examination of groundwater flow and submarine groundwater discharge using methane concentration and carbon isotope ratio. 7) Numerical modeling studies for coastal groundwater flow system.

    The paper summed up the results of the geothermal development promotion survey B 'Kuwanosawa area' which was carried out in Yuzawa city, Akita prefecture, from FY 1998 to FY 1999. In the survey, the following were conducted for the comprehensive analysis: geology/alteration zone survey, gravity exploration, electromagnetic exploration, environmental effect survey, well geology survey by drilling structural boreholes of N11-KN-1 and N12-KN-2, cuttings test, temperature log, temperature recovery test, electrical log, water injection test, etc. The geology in the Kuwanosawa area is composed of Pre-neogene period basement rocks, Neogene system and Quaternary system. In this area, there were recognized no gush of geothermal fluids such as hot spring and fumarolic gas and no obvious geothermal manifestation such as high-temperature places and new geothermal alteration zones. Around N12-KN-2, there exists the geothermal water with comparatively high-temperature/high-Cl concentration which is similar to that in the Wasabizawa area, but how it flows is unknown because there was no lost circulation in the depths of the borehole. Around N11-KN-1, there exists the low-temperature/low-Cl concentration geothermal water originating in meteoric water, and therefore, the area can be a rechargeable area. The Kuwanosawa area is regarded as the periphery of the Wasabizawa-Akinomiya geothermal area. (NEDO)

    Understanding brain organization of speech production has been a principal goal of neuroscience. Historically, brain speech production has been associated with so-called Broca’s area (Brodmann area –BA- 44 and 45), however, modern neuroimaging developments suggest speech production is associated with networks rather than with areas. The purpose of this paper was to analyze the connectivity of BA47 ( pars orbitalis) in relation to language . A meta-analysis was conducted to assess the language network in which BA47 is involved. The Brainmap database was used. Twenty papers corresponding to 29 experimental conditions with a total of 373 subjects were included. Our results suggest that BA47 participates in a “frontal language production system” (or extended Broca’s system). The BA47  connectivity found is also concordant with a minor role in language semantics. BA47 plays a central role in the language production system.

    The paper summed up the results of the survey of the geothermal development promotion survey - Akinomiya area which was carried out in Yuzawa City and Ogachi Town, Akita Prefecture, from FY 1996 to FY 1999. In the survey, the following were conducted: surface survey such as the geological alteration zone survey, fluid geochemical survey, gravity survey and electromagnetic exploration, logging by drilling 8 boreholes, jetting test, etc. Further, using the data obtained from these, analysis was made of geology/reservoir structure, thermal structure, hydraulic structure, etc. As a result, grasped were the distribution of the main underground fracture structure and the distribution of promising high-temperature zones. In the short-term/long-term jetting test, a total steam amount of 124 t/h was confirmed. Moreover, there was the pressure interference between the geothermal reservoir in the Akinomiya area and the geothermal reservoir in the Wasabizawa area, and it was confirmed that there was the hydraulic relation between those reservoirs. Further, it was assumed that there was not so much effect on hot spring reservoirs in the Akinomiya area. In the simulation of production prediction, the result was obtained that there was a possibility of power generation of 30MW only in the Akinomiya area and of 60MW both in the Akinomiya area and the Wasabizawa area.

  13. Basic research on tectonic reconstruction on the basis of paleomagnetic methods

    International Nuclear Information System (INIS)

    2003-03-01

    It is of great importance to clarify deformation mode in an extensive tectonic event in order to evaluate stability of rock masses. Although such evaluation is based on structural geology in general, conventional methods are of little use for understanding of the temporal and spatial changes in deformation mode accompanying rotational motions, which are brought about by relatively large fault movements. Therefore, deformation mode of rock masses are quantitatively evaluated in this report on the basis of paleomagnetic data. Arrangements of geologic units in the central Japan form a large northward cusp around the Izu Peninsula, which is interpreted as a result of intense deformation of rock mass by repeated collisions of the Izu-Bonin Arc against the Honshu Arc since the Miocene Period. As the Izu Peninsula is considered to be actively transported northward with slips on the Kannawa Fault, understanding for development process of collisional deformation zone is quite important to evaluate geological stability of rock masses. This report presents the paleomagnetic data of Miocene rocks obtained from a borehole in the Mizunami Underground Research Laboratory, in Mizunami City, Gifu Prefecture. Progressive demagnetization tests separated stable primary remanent magnetizations for the Toki Lignite-Bearing Formation and the Akeyo Formation in the early Miocene. Their declinations are characterized by a significant easterly deflection reflecting a tectonic event probably linked to the Japan Sea opening. Comparison of the contemporaneous paleo-magnetic data reported from the central Japan implies that a boundary of relative rotational motions under the influence of collision of the Izu-Bonin Arc exists between the Mizunami area and eastern areas, for example, Kakegawa area.

    This paper summarizes the result of a survey for promotion of geothermal development and an overall analysis of the Akinomiya area in fiscal 1996. The subject area is located in Katsuo Town in south of Akita Prefecture. The geothermal reservoirs are regulated by the irregular construction created by upheaval and subsidence of the pre-Tertiary basement rocks. The underground temperature construction shows the temperatures rising toward Mt. Yamabushi. The latest geothermal activities should have taken place after the eruption of Mt. Takamatsu. The geothermal activities near the Arayu area have been most active until recently, and is still predominant. Transformation activities were active in the former period of the Pleistocene era. The acidic transformation band has been active after sedimentation of andesites in Mt. Takamatsu thereafter, which should have been active not only in areas where it is now active on the ground surface, but also in greatly wider areas. Geothermal fluid flows being regulated by faults, whereas fractures with high permeability existing along the faults are suitable for developing steam collection. Hot spring waters were produced by the geothermal fluid having risen along the faults and been mixed with and diluted by ground surface water near the ground surface. Areas promising for geothermal development would spread over the areas with high permeability along structural lines such as faults which show the convection type temperature pattern and temperatures higher than 250 degrees C.

    To clarify the validity of the health habit index, we evaluated risk of death by health habit index in residents in Aichi Prefecture. Subjects were 7,662 residents aged 40-79 years living in a rural area of Aichi Prefecture who responded to a questionnaire in 1988, that included 12 health habit items on diet, physical activity, rest, mental health, smoking, drinking and regular health check. Data on death and migration in this cohort group was collected from 1990 to 1997. The risk ratios (RRs) of death for all causes, cancer and cardiovascular diseases were estimated by Cox's proportional hazard model. The number of all causes of death, cancer and cardiovascular diseases was 650, 240 and 197, respectively. Proper health habits of adequate but not over eating, regular physical activity, properly managing stress, non-smoking or smoking cessation for one year or more and regular health examinations in men and regular physical activity and non-smoking in women related to lower age-adjusted RR of death for all causes, while smoking cessation of less than one year in men with increased RR. Lower RR of cancer was observed for non-smoking men, and for women who occasionally have enough sleep. Proper health habits on adequate but not overeating, enjoying mealtime, regular physical activity, properly managing stress, moderate drinking (habit index in the present study included various items with or without association to risk for death. It is important to apply this index to health promotion on the basis of its specific characteristic.

    Protected areas are controversial because they are so important for conservation and because they distribute fortune and misfortune unevenly. The nature of that distribution, as well as the terrain of protected areas themselves, have been vigorously contested. In particular, the relationship between protected areas and poverty is a long-running debate in academic and policy circles. We review the origins of this debate and chart its key moments. We then outline the continuing flashpoints and ways in which further evaluation studies could improve the evidence base for policy-making and conservation practice. © 2015 The Authors.

    This work is a part of LIFE+ AGROCLIMAWATER project and the aim is to improve the water efficiency, increase the adaptive capacity of tree corps and save water, in a Mediterranean area, under different climatic conditions and agricultural practices. The experimental design as well as preliminary results at farm and river basin scales are presented in this work. Specifically, ten (10) pilot farms, both organic and conventional ones have been selected in the sub-basin of Platanias in western Crete - Greece. These ten pilot farms were selected representing the most typical crops in Platanias area (olive trees and citrus trees), as well as the typical soil, landscape and agricultural practices differentiation for each crop (field slope, water availability, soil type, management regime). From the ten pilot farms, eight were olive farms and the rest two citrus. This proportion correspond adequacy to the presentence of olive and citrus crops in the extended area of Platanias prefecture. Each of the ten pilot farm has been divided in two parts, the first one will be used as a control part, while the other one as the demonstration part where the interventions will be applied. The action plans for each selected farm are based on the following groups of possible interventions: a) reduction of water evaporation losses from soil surface, b) reduction of transpiration water losses through winter pruning and summer pruning, c) reduction of deep percolation water and nutrient losses, d) reduction of surface runoff, e) measures in order to maximize the efficiency of irrigation and f) rationalization of fertilizers and agrochemicals utilized. Preliminary results indicate that water saving and crop yield can be significantly improved based on the above innervations both at farm and river basin scale.

    In January 1994, the US Department of Energy Office of Environmental Management (DOE EM) formally introduced its new approach to managing DOE`s environmental research and technology development activities. The goal of the new approach is to conduct research and development in critical areas of interest to DOE, utilizing the best talent in the Department and in the national science community. To facilitate this solutions-oriented approach, the Office of Science and Technology (EM-50, formerly the Office of Technology Development) formed five Focus AReas to stimulate the required basic research, development, and demonstration efforts to seek new, innovative cleanup methods. In February 1995, EM-50 selected the DOE Morgantown Energy Technology Center (METC) to lead implementation of one of these Focus Areas: the Decontamination and Decommissioning (D & D) Focus Area.

    Japan Anti-Tuberculosis Association (JATA) (12)-variable numbers of tandem repeats (VNTR) is a standard method for genotyping of clinical isolates of Mycobacterium tuberculosis in Japan. As a model study for nationwide surveillance, this study aimed to describe the tendency and frequency of genotypes of M. tuberculosis in a large number of clinical samples. Clinical isolates of M. tuberculosis (n = 1,778) were obtained from patients with tuberculosis in 3 areas, i.e., Osaka City, Osaka Prefecture, and Kobe City, during 2007 and 2008. The samples were analyzed using JATA (12)-VNTR. All genotypes were subjected to clustering analysis. In total, 1,086 (61.1%) isolates showed clustering. The most common clusters were composed of 3 members. Such clusters were considered to reflect either actual transmission or low discriminatory power of JATA (12)-VNTR. Several prevalent JATA(12)-VNTR genotypes formed large clusters and were discussed in relation with epidemiological findings of other studies. The findings of this study will aid in the construction of an effective genotyping-based surveillance system of M. tuberculosis, through improvement of interpretation of VNTR types, observation of certain particular strains in an area, and efficient detection of unidentified outbreaks.

  15. Evaluation of air temperature distribution using thermal image under conditions of nocturnal radiative cooling in winter season over Shikoku area

    Using the thermal images offered by the infra-red thermometer and the LANDSAT, the air temperature distribution over mountainous regions were estimated under conditions of nocturnal radiative cooling in the winter season. The thermal image analyses by using an infra-red thermometer and the micrometeological observation were carried out around Zentsuji Kagawa prefecture. At the same time, the thermal image analyses were carried out by using the LANDSAT data. The LANDSAT data were taken on Dec. 7, 1984 and Dec. 5, 1989. The scenes covered the west part of Shikoku, southwest of Japan.The results were summarized as follows:Values of the surface temperature of trees, which were measured by an infra-red thermometer, were almost equal to the air temperature. On the other hand, DN values detected by LANDSAT over forest area were closely related with air temperature observed by AMeDAS. Therefore, it is possible to evaluate instantaneously a spatial distribution of the nocturnal air temperature from thermal image.The LANDSAT detect a surface temperature over Shikoku area only at 21:30. When radiative cooling was dominant, the thermal belt and the cold air lake were already formed on the mountain slopes at 21:30. Therfore, it is possible to estimate the characteristic of nocturnal temperature distribution by using LANDSAT data.It became clear that the temperature distribution estimated by thermal images offered by the infra-red thermometer and the LANDSAT was useful for the evaluation of rational land use for winter crops

    Carotenoids are liposoluble pigments widely distributed in nature. More than 750 carotenoids are isolated from natural sources, but only a few kinds are used industrially. The production of carotenoid by microorganisms is to be expected, but few carotenoids originate from living things on land. And there is little knowledge about carotenoid-producing microorganisms in the oceans. The possibility still exists of discovering new carotenoid-producing microorganisms. Sunlight is very strong in subtropical regions. The surface of the sea and coral reefs in these regions is a severe environment for growth of microorganisms. While such conditions produce reactive oxygen species, the continuing strong irradiation can also lead to damaging and lethal photo-oxidative reactions. Many undiscovered microorganisms may possess protective mechanisms such as anti-oxidative activities for survival in this environment. This study focused on marine microorganisms inhabiting coral reefs in the Okinawa area, especially carotenoid-producing bacteria possessing anti-oxidative activities. Many carotenoid-producing microorganisms were collected from subtropical ocean areas (a total of 334 strains of pigmented microorganisms), and the chemical composition, some culture conditions and genetic characteristics of the carotenoids from these microorganisms were examined. Furthermore, similar research was performed using some creatures from the ocean surrounding Kochi Prefecture.

    The objective of this study was to define areas of previous disturbance in the 300 Area of the U.S. Department of Energy (DOE) Hanford Site to eliminate these areas from the cultural resource review process, reduce cultural resource monitoring costs, and allow cultural resource specialists to focus on areas where subsurface disturbance is minimal or nonexistent. Research into available sources suggests that impacts from excavations have been significant wherever the following construction activities have occurred: building basements and pits, waste ponds, burial grounds, trenches, installation of subsurface pipelines, power poles, water hydrants, and well construction. Beyond the areas just mentioned, substrates in the' 300 Area consist of a complex, multidimen- sional mosaic composed of undisturbed stratigraphy, backfill, and disturbed sediments; Four Geographic Information System (GIS) maps were created to display known areas of disturbance in the 300 Area. These maps contain information gleaned from a variety of sources, but the primary sources include the Hanford GIS database system, engineer drawings, and historic maps. In addition to these maps, several assumptions can be made about areas of disturbance in the 300 Area as a result of this study: o o Buried pipelines are not always located where they are mapped. As a result, cultural resource monitors or specialists should not depend on maps depicting subsurface pipelines for accurate locations of previous disturbance. Temporary roads built in the early 1940s were placed on layers of sand and gravel 8 to 12 in. thick. Given this information, it is likely that substrates beneath these early roads are only minimally disturbed. Building foundations ranged from concrete slabs no more than 6 to 8 in. thick to deeply excavated pits and basements. Buildings constructed with slab foundations are more numerous than may be expected, and minimally disturbed substrates may be expected in these locations. Historic

    Traffic on the Route 6 will increase after the revision of evacuation area and restricted area. At the request of the Local Nuclear Emergency Response Headquarters established in Fukushima Prefecture, Japan Nuclear Energy Safety Organization (JNES) has surveyed the effect on cars and drivers traveling through the Route 6 in the restricted area as listed bellow. (1) Investigation of contamination of cars traveling through the Route 6. (2) Investigation of exposure dose of drivers traveling through the Route 6. The maximum contamination at the surface of tires and tire-houses of cars traveling through the Route 6 is estimated to be 2 Bq/cm 2 (this concentration is correspond to 470 cpm). The external exposure dose of drivers will be about 4 μSv when they run through the restricted area at a pace of 40 km/h. The internal exposure dose will be small because of the low radioactive concentration in the air. It is important not to stay long in high radiation areas to prevent unnecessary exposure. The main source of the contamination is sand cloud thrown up by the wheels. Though, the radioactivity of the sand cloud is proportional to the surface concentration of roads and dose rate of each area, contamination level by the sand cloud will remain low level. Significant contamination is likely to be caused by running on the soil. So, it is important not to run on the soil on the local road around the Route 6 or road shoulder of the Route 6. It is recommended to wash tires and tire-houses when accidentally run on the soil. (author)

    The paper summed up the results of the geothermal development promotion survey B 'Mt. Tsujinodake area' which was carried out at Yamagawa town, Ibusuki county, Kagoshima prefecture, from FY 1997 to FY 1999. In the survey, the following were conducted: surface survey such as geology/alteration zone survey, fluid geochemical survey, gravity exploration and electromagnetic exploration, and geothermal fluid survey by drilling 4 structural testing boreholes. In the Mt. Tsujinodake area, active fumarolic activities are still now continuing around the Unagi hot spring in the north, and the acidic alteration zone is distributed in the peripheral surface area. In Borehole N11-TD-2 in the north, it is assumed that there exists the hydrothermal bed of a temperature of approximately 230 degrees C in the depth of 400-800m, which is comparatively shallow, and that the stored geothermal water flows laterally. In the central area, a hydrothermal bed of a temperature of approximately 130 degrees C was confirmed in N11-TD-1, but it is judged that chances of the existence of high temperature hydrothermal bed are not very good. In N11-TD-3 in the south, the existence of promising heat sources is expected in the deeper part since the remarkable alteration was seen in the depth of 1,435m or deeper, and the sharp rise in temperature was recognized.

    With regard to the Ashiro Town area in Iwate Prefecture, this paper reports the result of evaluations based on temperature and pressure logging after a lapse of an extended period of time (well No.2) and a steam jet test (well No.1). These activities were performed as the survey on promotion of geothermal development and survey on development feasibility in fiscal 1997. As a result of the overall analysis based on the present survey and ones in the past, the geothermal system model in the surveyed area may be conceived as follows: in both of the N7-AR-1 and N7-AR-2 wells drilled in the southern part of the surveyed area, temperature as high as 250 degrees C or higher was confirmed; the underground temperature is 200 degrees C or higher at an altitude level of zero meter and 250 degrees C at around -500 m, leading to a belief that the high temperature area spreads to south; as a fracture system holding geothermal fluid, a fault was identified at the N7-AR-1 well drilling depth of 1710 m; in the steam jet test, a geothermal reservoir (a shallow geothermal reservoir) was confirmed to exist; the geothermal fluid that has jetted out shows alkaline Na-SO{sub 4} type; and the deep geothermal reservoir has high temperature and is presumed to be in the two-phase condition, presenting promising factors as the geothermal resources.

    Solid state lighting using LED-dies is a rapidly growing market. LED-dies with the needed increasing luminous flux per chip area produce a lot of heat. Therefore an appropriate thermal management is required for general lighting with LEDdies. One way to avoid overheating and shorter lifetime is the use of many small LED-dies on a large area heat sink (down to 70 μm edge length), so that heat can spread into a large area while at the same time light also appears on a larger area. The handling with such small LED-dies is very difficult because they are too small to be picked with common equipment. Therefore a new concept called collective transfer bonding using a temporary carrier chip was developed. A further benefit of this new technology is the high precision assembly as well as the plane parallel assembly of the LED-dies which is necessary for wire bonding. It has been shown that hundred functional LED-dies were transferred and soldered at the same time. After the assembly a cost effective established PCB-technology was applied to produce a large-area light source consisting of many small LED-dies and electrically connected on a PCB-substrate. The top contacts of the LED-dies were realized by laminating an adhesive copper sheet followed by LDI structuring as known from PCB-via-technology. This assembly can be completed by adding converting and light forming optical elements. In summary two technologies based on standard SMD and PCB technology have been developed for panel level LED packaging up to 610x 457 mm2 area size.

    On the basis of mineral-resource surveys the Selkirk Roadless Area, Idaho has little promise for the occurrence of mineral or energy resources. Molybdenum, lead, uranium, thorium, chromium, tungsten, zirconium, and several rare-earth elements have been detected in panned concentrates from samples of stream sediment, but no minerals containing the first five elements were found in place, nor were any conditions conducive to their concentration found. Zirconium, thorium, and the rare earths occur in sparsely disseminated accessory minerals in granitic rocks and no resource potential is identified. There is no history of mining in the roadless area and there are no oil, gas, mineral, or geothermal leases or current claims.

    This report presents an overview of urban problem areas. RIVM made an inventory of environmental problems in urban regions in the Netherlands due to air pollution, noise, potential soil pollution and external safety risks. Environmental problems (exposure or exposure risks) were related to the presence of dwellings in each postal area where critical limit values are exceeded. From the inventory, it appears that the critical exposure values are exceeded at many dwellings. Exceedences are often caused by air pollution (particulate matter and nitrogen oxide) and noise from road- and railway traffic. Many of these dwellings can be found in major cities with ringways (Amsterdam, Rotterdam, Den Haag, Utrecht ) and also in the Province of Noord-Brabant. Inventories are presented in a set of color coded maps, showing the type of environmental damage occurring and indicating the number of dwellings critically exposed in each postal area. The maps give policy makers and urban planners an overall picture of the residential areas demanding attention from an environmental point of view [nl

More than 5,700 known DOE groundwater plumes have contaminated over 600 billion gallons of water and 200 million cubic meters of soil. Migration of these plumes threatens local and regional water sources, and in some cases has already adversely impacted off-site rsources. In addition, the Subsurface Contaminants Focus Area is responsible for supplying technologies for the remediation of numerous landfills at DOE facilities. These landfills are estimated to contain over 3 million cubic meters of radioactive and hazardous buried Technology developed within this specialty area will provide efective methods to contain contaminant plumes and new or alternative technologies for development of in situ technologies to minimize waste disposal costs and potential worker exposure by treating plumes in place. While addressing contaminant plumes emanating from DOE landfills, the Subsurface Contaminants Focus Area is also working to develop new or alternative technologies for the in situ stabilization, and nonintrusive characterization of these disposal sites

    To ensure research and development programs focus on the most pressing environmental restoration and waste management problems at the U.S. Department of Energy (DOE), the Assistant Secretary for the Office of Environmental Management (EM) established a working group in August 1993 to implement a new approach to research and technology development. As part of this new approach, EM developed a management structure and principles that led to the creation of specific Focus Areas. These organizations were designed to focus the scientific and technical talent throughout DOE and the national scientific community on the major environmental restoration and waste management problems facing DOE. The Focus Area approach provides the framework for intersite cooperation and leveraging of resources on common problems. After the original establishment of five major Focus Areas within the Office of Technology Development (EM-50, now called the Office of Science and Technology), the Nuclear Materials Stabilization Task Group (EM-66) followed the structure already in place in EM-50 and chartered the Plutonium Focus Area (PFA).

    Outdoor decontamination efforts have been ongoing since the Fukushima Daiichi nuclear power plant (FDNPP) accident; however, little is known about indoor contamination. Therefore, house dust was sampled based on particle size in 21 wooden buildings (19 residential houses and 2 community centers) within the evacuation area close to the FDNPP, Fukushima Prefecture, Japan. Activities of radiocesium ( 137 Cs) per gram of house dust increased with decreasing particle size (mean: 6.1 × 10 3 , 2.6 × 10 3 , 1.6 × 10 3 , 7.5 × 10 2 , 5.0 × 10 2 , and 4.6 × 10 2  Bq/g for <4-20, 20-63, 63-180, 180-500, 500-1000, and 1000-2000 μm, respectively). The 137 Cs concentrations in house dust were inversely related to the square of distance from the FDNPP for <4-1000 μm particles. From the results of the multiple linear regression analysis, distance from the FDNPP and direction from the FDNPP (northwest) were significantly related to the radioactivity of house dust. It was found that 19%, 33%, and 48% of 137 Cs in house dust were extracted in water, 1 M HCl, and not extracted, respectively. Considering the bioaccessibility and assuming a 20 mg/day daily intake of house dust, the daily doses would be 7.2 Bq/day (mean) and 18 Bq/day (95th percent quantile). These results provide valuable insight into indoor radioactive Cs contamination in the area around the FDNPP and possible oral exposure to indoor radioactive Cs after returning home.

  12. Tsunami hazard mitigation in tourism in the tropical and subtropical coastal areas: a case study in the Ryukyu Islands, southwest of Japan

    2006-12-01

    Life and economy (including tourism) in tropical and subtropical coastal areas, such as Okinawa Prefecture (Ryukyu) are highly relying on the sea. The sea has both "gentle" side to give people healing and "dangerous" side to kill people. If we are going to utilise the sea for marine tourism such as constructing resort facilities on the oceanfront, we should know all of the sea, including the both sides of the sea: especially the nature of tsunamis. And also we islanders should issue accurate information about the sea towards outsiders, especially tourists visiting the island. We have already learned a lesson about this issue from the Sumatra tsunami in 2004. However, measures against the tsunami disaster by marine tourism industry are still inadequate in these areas. The goal of tsunami hazard mitigation for those engaged in tourism industry in tropical and subtropical coastal areas should be as follows. (1) Preparedness against tsunamis: "Be aware of the characteristics of tsunamis." "Prepare tsunamis when you feel an earthquake." "Prepare tsunamis when an earthquake takes place somewhere in the world." (2) Maintenance of an exact tsunami hazard map under quantitative analyses of the characteristics of tsunamis: "Flooding areas by tsunami attacks are dependent not only on altitude but also on amplification and inundation due to the seafloor topography near the coast and the onland topographic relief." "Tsunami damage happens repeatedly." (3) Maintenance of a tsunami disaster prevention manual and training after the manual: "Who should do what in case of tsunamis?" "How should the resort hotel employees lead the guests to the safe place?"

    1989-01-01

    The paper deals with the problem of contaminated areas cleanup, in order to eliminate every possible damage for man safety and environment and to site recovery for some utilization, The first step of cleanup operation is site characterization, that is followed by a pianificazion activity for a better definition of staff qualification, technology to be used, protection and prevention instruments for the risks due to contaminants handling. The second section describes the different remedial technologies for contaminated sites. Remedial technologies may be divided into on-site/off-site and in-situ treatments, according to whether materials (waste, soil, water) are moved to another location or not, respectively. Finally, it is outlined that contaminated areas cleanup is a typical multidisciplinary activity because very different competences are required. (author)

    Full Text Available Quality of bronchoscopy performed by one single pulmonologist in a scarcely populated subarctic area was compared to the guidelines provided by the British Thoracic Society (BTS. 103 patients underwent bronchoscopy. Diagnostic yield was increased to 76.6% when the first bronchoscopy was supplemented by bronchial washing fluid and brush cytology and to 86.7% (BTS guidelines >80% after a second bronchoscopy. Median time from referral to bronchoscopy was 10 days and 8 days from positive bronchoscopy to operative referral to another hospital. 1% of patients that underwent transbronchial lung biopsy had minor complications. One pulmonologist had rate of correct diagnosis based on visible endobronchial tumors that was comparable to the rates of numerous pulmonologists at larger centers performing the same procedure. Time delay was short. Rate of complications was comparable. Bronchoscopy performed by one pulmonologist alone could, in organized settings, be carried out at local hospitals in areas of scattered settlement.

    Calcite (CaCO3) is important in many fields—in nature, because it is a component of aquifers, oil reservoirs and prospective CO2 storage sites, and in industry, where it is used in products as diverse as paper, toothpaste, paint, plastic and aspirin. It is difficult to obtain high purity calcite with a high surface area but such material is necessary for industrial applications and for fundamental calcite research. Commercial powder is nearly always contaminated with growth inhibitors such as sugars, citrate or pectin and most laboratory synthesis methods deliver large precipitates, often containing vaterite or aragonite. To address this problem, we (i) adapted the method of carbonating a Ca(OH)2 slurry with CO2 gas to develop the first simple, cheap, safe and reproducible procedure using common laboratory equipment, to obtain calcite that reproducibly had a surface area of 14-17 m2/g and (ii) conducted a thorough characterization of the product. Scanning electron microscopy (SEM) revealed nanometer scale, rhombohedral crystals. X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and infrared spectroscopy (IR) confirmed highly crystalline, pure calcite that more closely resembles the dimensions of the biogenic calcite produced by algae in coccoliths than other methods for synthesizing calcite. We suggest that this calcite is useful when purity and high surface area are important.

  17. Frostbites in circumpolar areas

    Directory of Open Access Journals (Sweden)

    Tiina Maria Ikäheimo

    2011-10-01

    Full Text Available Circumpolar areas are associated with prolonged cold exposure where wind, precipitation, and darkness further aggravate the environmental conditions and the associated risks. Despite the climate warming, cold climatic conditions will prevail in circumpolar areas and contribute to adverse health effects. Frostbite is a freezing injury where localized damage affects the skin and other tissues. It occurs during occupational or leisure-time activities and is common in the general population among men and women of various ages. Industries of the circumpolar areas where frostbite occurs frequently include transportation, mining, oil, and gas industry, construction, agriculture, and military operations. Cold injuries may also occur during leisure-time activities involving substantial cold exposure, such as mountaineering, skiing, and snowmobiling. Accidental situations (occupational, leisure time often contribute to adverse cooling and cold injuries. Several environmental (temperature, wind, wetness, cold objects, and altitude and individual (behavior, health, and physiology predisposing factors are connected with frostbite injuries. Vulnerable populations include those having a chronic disease (cardiovascular, diabetes, and depression, children and the elderly, or homeless people. Frostbite results in sequelae causing different types of discomfort and functional limitations that may persist for years. A frostbite injury is preventable, and hence, unacceptable from a public health perspective. Appropriate cold risk management includes awareness of the adverse effects of cold, individual adjustment of cold exposure and clothing, or in occupational context different organizational and technical measures. In addition, vulnerable population groups need customized information and care for proper prevention of frostbites.

    The paper summed up the results of the survey of the geothermal development promotion survey - Wasabizawa area which was carried out in Yuzawa City and Ogachi Town, Akita Prefecture, from FY 1993 to FY 1996. In the survey, the following were conducted: surface survey such as geological alteration zone survey, fluid geochemical survey, gravity survey and electromagnetic exploration, temperature log by drilling 9 exploration wells, short-term/long-term jetting test, etc. Further, using the data obtained from these, analysis was made of geology/reservoir structure, thermal structure, geothermal water/hydraulic structure, geothermal system models, etc. As a result, a high-temperature (about 300 degrees C) zone promising as the geothermal development area was picked out, and the existence was confirmed of a dominant geothermal reservoir around the fault. In the jetting test, a total steam amount of 111.6 t/h was confirmed, and from the reservoir simulation, the result was obtained that there was a high possibility of 30-year power generation of 30MW/y. As a result of studying 'a power generation system by small-scale unit serial development' considering regional characteristics in the Wasabizawa area, the power generation cost (sending end, 15-year average) was estimated at approximately 9-10 yen/kWh.

    A 3D seismic experiment was carried out in the Minaminoshiro area in Akita Prefecture, an area difficult of performing seismic exploration. This paper reports progresses during data processing and future problems. The data processing has executed static correction of 3D refraction, 3D DMO correction, and an F-X prediction filter processing on the data in time domain in the 3D seismic exploration as acquired in a spread of 4 km times 5 km in the subject area. The result of the data processing verified existence of a folding structure and the Noshiro thrust fault groups in the east to west direction, and locations of the Sakagawa fault associated therewith. Seen particularly noticeably was a structure having a slope falling north-ward at 15 to 35 degrees in shallow and deep portions on the east side of the Sakagawa fault in the south to north direction. In addition, the Dogiri fault was identified, which has been though to exist in a direction crossing perpendicularly the Noshiro thrust fault groups. It is scheduled that spatial velocity will be analyzed, and data processing will be conducted for deep regions. 7 figs.

    The National Institute of Agro-environmental Sciences conducts a monitoring survey of variation of the ground water quality and a survey to grasp the actual status in each region of Japan. This data includes a well water quality monitoring survey in the Inashiki plateau and its circumferencial area in Ibaraki prefecture, survey of the actual state of ground water quality in the same area, survey of the actual status of ground water quality in each region of the country, survey to grasp quality of the ground water from river revetment, and data on quality of water discharged from patty field conduits. In a survey of adaptability of the water quality standard, CL, COD and total hardness of the usual well water and spring water were below the standard level except for a part of the waters. It was found out that forest areas formed on mountains and slopes of plateaus hold ground water with good quality from a viewpoint of the NO3-N concentration, but there are some cases in which pH does not match water quality standards. Even patty fields hold good-quality ground water, but patty fields adjacent to fields sometimes show the concentration exceeding the water quality standard. 9 refs., 37 figs., 20 tabs.

    Precise estimation of tree density in the forest leads us to understand the amount of carbon dioxide fixed by plants. Aerial photographs have been used to measure the number of trees. Campaign using aircraft, however, is expensive ( $50,000/1 campaign flight) and the research area is limited in drone. In addition, previous studies estimating the density of trees from aerial photographs have been performed in the summer, so there was a gap of 15% in the estimation due to the overlapping of the leaves. Here, we have proposed a method to accurately estimate the number of forest trees from the satellite images of snow-covered deciduous forest area, using the ratio of branches to snow. The advantages of our method are as follows; 1) snow area could be excluded easily due to the high reflectance, 2) tree branches are small overlapping compared to leaves. Although our method can use only in the snowfall region, the area covered with snow in the world becomes more than 12,800,000 km2. Our proposition should play an important role in discussing global warming. As a test area, we have chosen the forest near Mt. Amano in Iwate prefecture in Japan. First, we made a new index of (Band1-Band5)/(Band1+Band5), which will be suitable to distinguish between the snow and the tree trunk using the corresponding spectral reflection data. Next, the index values of changing the ratio in 1% increments were listed. From the satellite image analysis at 4 points, the ratio of snow to tree trunk showed the following values, I:61%, II:65%, III:66% and IV:65%. To confirm the estimation, we used the aerial photograph from Google earth; the rate was I:42.05%, II:48.89%, III:50.64%, IV:49.05%, respectively. There is a correlation between the numerical values of both, but there are differences. We will discuss in detail at this point, focusing on the effect of shadows.

    The natural radionuclides as K-40, uranium decay series and thorium decay series etc. are widely distributed on environment, but are not uniformly. These have various forms as the sources of terrestrial environmental γ radiation and of radon and make wide fluctuation seasonal and spatially on the environment. We have selected Ikeda mineral spring district, Shimane pref., Misasa spa district, Tottori pref., Muro district, Hachibuse district, Nara pref. and Arima spa district, Hyogo-pref. for HBRA, and Kawanishi-shi, Hyogo pref. and Higashi-osaka-shi, Osaka pref. as CA. We have carried out the study on the environmental movement and distribution of natural radioactive nuclides containing radon and decay nuclides. Radon measurements have been carried using cup typed radon and thoron monitors, pico-rad method by active charcoal sampling and Pilon scintillation-cell by grub sampling. Accumulated radon monitors have been used with cellulose nitrate as solid state track detector. Rn-222 concentrations in air at Misasa spa ranged 2 - 150 Bq/m 3 outdoor and 8 - 194 Bq/m 3 indoor. Rn-222 concentrations on Misasa district, Asahi district and Takeda district geologically formed from granite strata are high, and those on Osika district and Mitoku district formed from volcanic rocks (Andesite and Basalt) are low level. Rn-222 concentration variations in well water used as drinking water were 2 - 138 Bq/l (mean value 31 Bq/l) and those in ground waters varied from non detectable to 4620 Bq/l (mean 875 Bq/l) on sampling time and places. Mean Rn-222 concentration in the spring water at Arima spa area, Hyogo prefecture is 26 Bq/l at Tansan spring source and the other spring sources are comparatively low level. (J.P.N.)

    As part of the geothermal development promotion survey, the comprehensive analysis was made on the survey of the existence amount of geothermal resource in the Akinomiya area, Ogachi town, Akita prefecture, which was conducted in FY 1999. In the evaluation of reservoirs, the following were carried out: comprehensive analysis of various data on the surface survey, well exploration, etc., which were stored in surveys from the primary to the forth, modification/construction of geothermal system models, numerical simulation using 3D models, etc. In the long-term jetting test, production/reduction tests were conducted using N9-AY-3 and N10-AY-8 as production wells and N8-AY-1 and N10-AY-6 as reduction wells. The results of the comprehensive analysis were outlined as follows. The distribution of high temperature zones promising as areas for geothermal development was grasped. The distribution of the main fracture structure underground was grasped. A total amount of 124t/h steam was confirmed by short/long term jetting tests. In the simulation of prediction of production, the result was obtained that there was potential power generation of 30MW in the Akinomiya area alone and 60MW both in the Akinomiya area and the Wasabizawa area.

    The geothermal development promotion survey was conducted in the Akinomiya area, Ogachi county, Akita prefecture, and the FY 1998 results were summed up. In the surface survey, geology/electromagnetism/precision gravity survey was made as supplementary survey, and re-analysis of 3D models was made. In the well survey, three wells of N10-AY-6 to N10-AY-8 were drilled to conduct the core examination, temperature/pressure logging, sampler logging, short-term jetting test, etc. Also conducted were the reservoir evaluation, environmental effect survey, etc. by pressure monitoring and water level observation. The results of the comprehensive analysis predict the following. In the Akinomiya area, there exists heat source in deep parts around Mt. Yamabushi-dake and Mt. Takamatsu-dake; Being given heat from this heat source, rocks, ground water and volcanic gas react on each other to form geothermal fluids. It is presumed that high temperature geothermal reservoirs exist in the east of the area. Moreover, the pressure distribution indicates that the Akinomiya reservoir and Wasabizawa reservoir can be a chain hydraulically. On the other hand, the west of the area is the low temperature and heat conductive area, and therefore, there seem to be no high temperature fluids there. (NEDO)

    The background γ-ray intensity and chemical composition of soil was determined in the Naka terrace of Tokai-mura Village and Hitachinaka City, where many nuclear facilities are located. The aim of the sampling was to assess environmental radiation within the Naka terrace and the sites of nuclear facilities. The study was initiated following the JCO Criticality Accident on September 30th, 1999. γ-ray measurement and soil sampling were conducted at the nodes of a 500 m grid. The γ-ray intensity recorded at all sample points is less than the average radiation of Japanese granites and less than the typical radiation of humans as assessed by UNSCREA. The chemical characteristics of the soil are divided into 3 types. The distribution of both the soil types and background γ-ray intensity is controlled by geographical and geological factors. K 2 O and Rb concentrations within the soil show a good correlation with background γ-ray intensity. Our observations indicate that environmental radiation within the study area is derived principally from natural radioisotope radiation. (author)

Rural tourism in Croatia based on family farma faces a number of problems legal foundations, the involement of local communities, inadequate entepreneur support etc. The political will for development exists, but there is lack of willingness and the ability to get things started, which results in the closure of family farma who cannot cope with the parallel job of agriculture and tourism. Arriving guests certainly want a new type of tourism: peace, clean environment, cultural intangible and tangible treasures, all without the noise and stress; and Croatia can definitely offer it, either in coastal or inland areas with traditional food and drinks. The destinations connection is not satisfactora. there is also an evident lack of legislation and regional spatial development plans for sustainable tourism which is a prerequisite for successful tourism. With these plans presumptins accepted, Croatian tourism would become distinctive and inland and coastal branches of tourism could complement each other so that the customer can spend his vacation both in the continental ant the maritime part of the country, getting to know our culture and enjoy the traditional cousine.

    1986-02-01

    A literature study was conducted in order to compare the effectiveness and cost of different reclamation procedures that may be employed after an accident on a nuclear facility takes place in which radioactive material is released to the atmosphere. A substantial amount of work has been done on reclaming soil and snow-covered surfaces. Using scrapers or other soil-moving equipment decontamination factors are 10-100. (The decontamination factor is the ratio of the contamination before to that after the decontamination procedure). However, information on decontamination of paved areas by simple methods such as firehosing and vacuum sweeping are poorly documented. Therefore, only a very uncertain figure in the range 2-10 can be given for the decontamination factor here. It is recommended that a major effort be made in the future to investigate the efficiency of these simple methods, because of their relatively low cost. Also, more expensive methods for reducing the dose such as vacuuming, road planing and deep plowing are treated because of their feasibility under certain circumstances. Using these methods dose reduction factors in the 2-100 range can be obtained. Very expensive techniques, such as sandblasting, water cannon, flame spalling, etc. are justifiable usable only in special situations and are therefore considered very briefly here. The methods vary widely in cost. A simple method like vacuum sweeping costs $0.004 per square meter of surface; whereas one like road planing can reach $4 per square meter. A more sophisticated technique like flame spalling costs as much as $100 per square meter. (author)

    This paper describes effects of the disturbance by the sand compaction pile (SCP) driving operations on the shear strength of clay outside the improved area and the border of region affected by the SCP driving. About 1,400 soil specimens were taken before and after the SCP driving inside and outside the improved area during the foundation improvement at Tokuyama-Shimomatsu Port in Yamaguchi Prefecture. Soil test data of the specimens and strength characteristics of disturbed clay specimens were investigated through the laboratory experiments. The results obtained are as follows. According to the multi-directional simple shear test results, the shear strength immediately after the cyclic shear decreased in 10 to 30% compared with that before the cyclic shear. When recompaction was conducted before the cyclic shear, however, it increased in 50% compared with that before the cyclic shear. The strength of clay decreased by the SCP driving even outside the improved area. When the internal frictional angle of clay, friction coefficient of the improved boundary and driving depth of SCP were determined, it was possible to estimate an area affected by the SCP driving using a combined sliding plane. 21 refs., 18 figs.

    The comprehensive analysis was conducted of various data obtained in the geothermal development promotion survey conducted in the Kuwanosawa area, Yuzawa city, Akita prefecture, from FY 1998 to FY 2000. The geology of the Kuwanosawa area consists of the Pretertiary system and Quarternary system, through which intrusive rocks are recognized. Basement rocks are composed of the Paleozoic-origin crystalline schist and the Cretaceous-period granites which intruded into the schist. In the Kuwanosawa area, there were recognized no clear geothermal signs such as the discharge of geothermal fluids like hot spring, fumarolic gas, etc., places of high temperature and new geothermal alteration zones. The geothermal water of borehole N11-KN-1 is a low temperature/low CL concentration geothermal water which was stored in basement rocks, which is supposed to be the one conductively heated in the process of the meteoric water penetrating deep-underground. The geothermal system heat source in the Kuwanosawa area and the periphery is regarded as the relic magma which spewed out the volcanic rocks of Mt. Takamatsu-dake in the Quaternary period. However, the geothermal fluid included no components originating in high temperature volcanic emissions, and therefore, it is considered that the geothermal fluid was formed by the meteoric water conductively heated by volcanic heat source.

    Objective: To understand the prevalence of dyslipidemia and normal blood lipids level in Uygur diabetes patients in Kashgar prefecture in southern area of Xinjiang. Methods: A total of 5 078 local residents aged ≥18 years (42.56 % were men) selected through cluster random sampling in Kashgar were surveyed by means of questionnaire survey, physical examination and laboratory test, and 521 diabetes patients were screened. Results: The overall prevalence of dyslipidemia in diabetes patients was 59.50 % (310/521) with adjusted rate as 49.39 % . Age ≥65 years, overweight, obesity and abdominal obesity increased the risk for dyslipidemia by 0.771 times (95 % CI : 1.015-3.088), 1.132 times (95 % CI : 1.290-3.523), 1.688 times (95 % CI : 1.573-4.592) and 0.801 times (95 % CI : 1.028-3.155) respectively. Compared with males, female was a protective factor for dyslipidemia ( OR =0.507, 95 %CI : 0.334-0.769). The overall normal rate of blood lipids level including total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) for type 2 diabetes patients was 11.13 % . Female, higher BMI and abdominal obesity were the factors influencing the overall normal blood lipids level. The normal rate of LDL-C level decreased with increase of age, BMI and waist circumferences (trend test χ (2)=18.049, P dyslipidemia in Uygur diabetes patients in Kashgar was high, however, the overall normal rate of blood lipid level was relatively low. Obesity was the most important risk factor for dyslipidemia in this area. More attention should be paid to dyslipidemia prevention in women.

    Full Text Available Background: In China, mosquito-borne diseases are most common in the sub-tropical area of Yunnan province. The objective of this study was to examine behaviors related to mosquito-borne diseases in different ethnic minority groups and different socioeconomic groups of people living in this region. Methods: A stratified two-stage cluster sampling technique with probability proportional to size was used in Mengla County, Xishuangbanna Prefecture, Yunnan. Twelve villages were used to recruit adult (≥18 years old and eight schools were used for children (<18 years old. A questionnaire on behaviors and environment variables related to mosquito-borne diseases was devised. Results: Multiple correspondence analysis (MCA grouped 20 behaviors into three domains, namely, environmental condition, bed net use behaviors, and repellent use behaviors, respectively. The Han ethnicity had the lowest odds of rearing pigs, their odds being significantly lower than those of Yi and Yao. For bed net use, Dai and other ethnic minority groups were less likely to use bed nets compared to Yi and Yao. The odds of repellent use in the Han ethnicity was lower than in Yi, but higher than in Dai. The Dai group was the most likely ethnicity to use repellents. Farmers were at a higher risk for pig rearing and not using repellents. Education of less than primary school held the lowest odds of pig rearing. Those with low income were at a higher risk for not using bed nets and repellent except in pig rearing. Those with a small family size were at a lower risk for pig rearing. Conclusion: Different ethnic and socioeconomic groups in the study areas require different specific emphases for the prevention of mosquito-borne diseases.

    Full Text Available Abstract Background Under-5-years child mortality remains high in rural China. Integrated management of childhood illness (IMCI was introduced to China in 1998, but only a few rural areas have been included. This study aimed at assessing the current situation of the health system of rural health care and evaluating the clinical competency of village doctors in management of childhood illnesses prior to implementing IMCI programme in remote border rural areas. Methods The study was carried out in the border areas of Puer prefecture of Yunnan province. There were 182 village doctors in the list of the health bureau in these border areas. Of these, 154 (84.6% were recruited into the study. The local health system components were investigated using a qualitative approach and analyzed with triangulation of information from different sources. The clinical component was assessed objectively and quantitatively presented using descriptive statistics. Results The study found that the New Rural Cooperative Medical Scheme (NRCMS coordinated the health insurance system and the provider service through 3 tiers: village doctor, township and county hospitals. The 30 RMB per person per year premium did not cover the referral cost, and thereby decreased the number of referrals. In contrast to available treatment facilities and drug supply, the level of basic medical education of village doctors and township doctors was low. Discontent among village doctors was common, especially concerning low rates of return from the service, exceptions being procedures such as injections, which in fact may create moral hazards to the patients. Direct observation on the assessment and management of paediatric patients by village doctors revealed inadequate history taking and physical examination, inability to detect potentially serious complications, overprescription of injection and antibiotics, and underprescription of oral rehydration salts and poor quality of counseling

    Five years after the 1997 Nakhodka oil spill in the Sea of Japan, seven bacterial strains capable of utilizing the heavy oil spilled from the Nakhodka Russian oil tanker were isolated from three coastal areas (namely Katano Seashore of Fukui Prefecture, Osawa and Atake seashores of Ishikawa Prefecture) and the Nakhodka Russian oil tanker after a 5-year bioremediation process. All bacterial strains isolated could utilize long-chain-length alkanes efficiently, but not aromatic, and all of them were able to grow well on heavy oil. Using 16S rDNA sequencing, most of the strains were affiliated to Pseudomonas aeruginosa. Comparing between the year 1997 (at the beginning of bioremediation process) and the year 2001 (after 5 years of bioremediation), there was no significant change in morphology and size of hydrocarbon-degrading bacteria during the 5-year bioremediation. Scanning and transmission electron microscopic observations revealed that a large number of hydrocarbon- degrading bacteria still existed in the sites consisting of a variety of morphological forms of bacteria, such as coccus (Streptococcus and Staphylococcus) and bacillus (Streptobacillus). On the application of bioremediation processes on the laboratory-scale, laboratory microcosm experiments (containing seawater, beach sand, and heavy oil) under aerobic condition by two different treatments (i.e., placed inside the building and outside the building) were established for bioremediation of heavy oil to investigate the significance of the role of hydrocarbon-degrading bacteria on them. There was no significant bacterial activity differentiation in the two treatments, and removal of heavy oil by hydrocarbon degrading bacteria in the outside building was slightly greater than that in the inside building. The values of pH, Eh, EC, and dissolved oxygen (DO) in two treatments indicated that the bioremediation process took place under aerobic conditions (DO: 1-6 mg/l; Eh: 12-300 mV) and neutral

    In a world in which the pace of cities is increasing, prompt access to relevant information is crucial to the understanding and regulation of land use and its evolution in time. In spite of this, characterization and regulation of urban areas remains a complex process, requiring expert human intervention, analysis and judgment. Here we carry out a spatio-temporal fractal analysis of a metropolitan area, based on which we develop a model which generates a cartographic representation and classification of built-up areas, identifying (and even predicting) those areas requiring the most proximate planning and regulation. Furthermore, we show how different types of urban areas identified by the model co-evolve with the city, requiring policy regulation to be flexible and adaptive, acting just in time. The algorithmic implementation of the model is applicable to any built-up area and simple enough to pave the way for the automatic classification of urban areas worldwide.

    Geothermal Resource area 9 encompasses all of Nye County, Nevada. Within this area there are many different known geothermal sites ranging in temperature from 70/sup 0/ to over 265/sup 0/ F. Fifteen of the more major sites have been selected for evaluation in this Area Development Plan. Various potential uses of the energy found at each of the resource sites discussed in this Area Development Plan were determined after evaluating the area's physical characteristics, land ownership and land use patterns, existing population and projected growth rates, and transportation facilities, and comparing those with the site specific resource characteristics. The uses considered were divided into five main categories: electrical generation, space heating, recreation, industrial process heat, and agriculture. Within two of these categories certain subdivisions were considered separately. The findings about each of the 15 geothermal sites considered in this Area Development Plan are summarized.

    The somatometric investigation was performed to see whether the environmental contamination by Fukushima Nuclear Power Plant Accident (Mar. 2011) had affected the growth of children through their life-style change in Ibaraki prefecture (the maximal estimated dose <5 mSv) neighboring on Fukushima. Subjects were 1,663/2,510 pupils of 4 primary schools of Kanuma, Ohtawara and Nikko cities, whose individual growth had been recorded in schools. Somatometry in the school had been conducted every 3 months, of which data were used for this investigation for the intervals of 1 year (Jan. 2011-2012), 5 months (Apr.-Sep. 2011) and 9 months (Apr. 2011-Jan. 2012). Differences of their body length, weight and change of body mass index between the intervals were analyzed statistically as well as their standard deviations with t- and F-test. No significant change in those indices of the cohort was found and thereby it was concluded that there was no effect of the disaster on the growth of school pupils in Ibaraki prefecture. (T.T.)

    The above-named survey had been scheduled to be conducted in fiscal years 1996-1998 for an approximately 10km{sup 2}-large area of Kokonoe-cho, Kusu-gun, Oita Prefecture. In fiscal 1996, surface surveys were conducted, such as geological and alteration zone surveys, gravity prospecting, and electromagnetic survey. In fiscal 1997, an exploration well (N9-KH-1: depth 2,222.0m) was drilled. Since the maximum temperature in the well was found to be so low as 78.5 degrees C, the survey was given up in the second year. The survey conducted at N9-KH-1 showed that deep-seated and shallow-seated ruptures developed there in the absence of aquicludes, and so it was inferred that it was a recharge area, as predicted by the temperature logging profile, with surface water flowing into the depth. The above showed that there was no deep-seated blind geothermal system which the survey was after. Since it was not likely that the shallow-seated geothermal system located in the southern part of the Mizuwake pass would be found expanding into the area of the current survey, it was decided that the survey not be carried forward to the following fiscal year.

    The paper summed up the results of the geothermal development promotion survey 'Mt. Aso West area' which was carried out at Choyo village and Kugino village, Aso county, and at Otsu town, Kikuchi county, Kumamoto prefecture, from FY 1991 to FY 1994. In the survey, the following were conducted for the comprehensive analysis: surface survey such as geology/alteration zone survey, geochemical survey and high precision MT method survey, and temperature log, electrical log, water injection test, core test and hydrothermal survey by drilling 7 structural boreholes. In the numerical analysis of thermal structure models, the present geothermal manifestation was obtained, assuming that the past magma reservoir in a state of agglomeration/semi-agglomeration exists in the depths of caldera and that the depth is set at 4km. It is assumed that the deep hydrothermal reservoir around Yunoya/Tarutama exists around the depth of 500-600m below sea level and that the temperature is 230-300 degrees C. The meteoric water permeating into the depths forms high-temperature reservoirs around Yunoya/Tarutama. The reservoir rises up to about 400m below sea level to become a vapor-dominated phase. It forms an acidic SO{sub 4} type reservoir phase around the earth surface. (NEDO)

    In order to understand the influence of the Fukushima Daiichi nuclear power plant accident on the ecosystem in hilly and mountainous areas of Fukushima Prefecture, chronological changes in the levels of radiocesium in arthropod species were investigated. From 2012 to 2014, arthropods from different trophic levels were sampled and the air radiation dose rates at the sampling sites were analyzed. The air radiation dose rates showed a significant and constant reduction over the 2 years at the sampling sites in Fukushima. The median radiocesium concentration ( 134 Cs +  137 Cs) detected in the rice grasshopper, Oxya yezoensis, and the Emma field cricket, Teleogryllus emma, dropped continuously to 0.080 and 0.078 Bq/g fresh weight, respectively, in 2014. In contrast, no significant reduction in radioactive contamination was observed in the Jorô spider, Nephila clavata, in which the level remained at 0.204 Bq/g in 2014. A significant positive correlation between radiocesium concentration and the air radiation dose rate was observed in the rice grasshopper, the Emma field cricket and the Jorô spider. The highest correlation coefficient (ρ = 0.946) was measured in the grasshopper. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Urban growth and sprawl have long put pressure on rural areas, leading to a growing zone of ‘rurban areas' where a multitude of functions, urban or rural, compete for land. The development is acknowledged in European spatial planning documents, which also recommend common solutions. E.......g. the spatial policy discussed and recommended in the European Spatial Development Perspective (ESDP) emphasises the compact city concept, rural-urban linkages and conservation of nature and cultural heritage. This paper compares planning practice for rurban areas in three cases: Roskilde municipality (Denmark......), Staffanstorp municipality (Sweden) and Werv-area (the Netherlands). All three areas belong to the rurban zone and are selected to exemplify pro-active planning.

    Cancer is regarded as abnormal cellular multiplication; it is not controlled by the organism, and its cells present a differentiated DNA. Initially, the disease does not show clinical signs, but it can be diagnosed by laboratory examinations. When tumors are present in the maxillofacial area, the carrier can lose structures in this area, resulting to the carrier's social environment exclusion. This article aims to show incidences and causes of malignant neoplasias in the maxillofacial area.

    This study examined the elder abuse cases that occurred in Gifu Prefecture, Japan between 1990 and 2000. We conducted a retrospective study of all the cases in which the victim was 65 years or older and autopsied in the Department of Legal Medicine, Gifu University School of Medicine. Fifteen victims were classified as elder abuse victims: five men and ten women. The victims ranged in age from 66 to 87 years (mean age, 74.5 years). The types of abuse were as follows: physical abuse, 13 cases; emotional abuse, five cases; neglect, four cases; and financial abuse, three cases. In eight cases, the victims were subjected to two or more types of abuse. The cause of death of the victims varied with the type of abuse. In the physical abuse cases, subdural hemorrhage was the most common cause, followed by other violence-related deaths and hypothermia. In the neglect cases, the victims died of either starvation or suffocation after the aspiration of food into the airway. In the domestic abuse cases, one of the victim's sons was the most common perpetrator, and little or no income was considered to be a risk factor for perpetrators. In the neglect cases, dementia and difficulty in performing activities of daily living were considered to be risk factors for victims, in addition to living in social isolation.

    Historical relationships between weather, the Canadian fire weather index (FWI) system components and area burned in Canadian ecozones were analysed on a monthly basis in tandem with output from the Canadian and the Hadley Centre GCMs to project future area burned. Temperature and fuel moisture were the variables best related to historical monthly area burned with 36-64% of the variance explained depending on ecozone. Our results suggest significant increases in future area burned although there are large regional variations in fire activity. This was especially true for the Canadian GCM where some ecozones show little change in area burned, however area burned was not projected to decrease in any of the ecozones modelled. On average, area burned in Canada is projected to increase by 74-118% by the end of this century in a 3 x CO2 scenario. These estimates do not explicitly take into account any changes in vegetation, ignitions, fire season length, and human activity (fire management and land use activities) that may influence area burned. However, the estimated increases in area burned would have significant ecological, economic and social impacts for Canada

On the other hand, 137 Cs concentrations were ranged from 2.1 to 240 Bq/kg-dry in 10 dried herbs imported from Europe. 40 K level was 99.9 - 1400 Bq/kg-dry in all dried herbs. Obvious regional differences of 137 Cs concentrations of 'eyebright' between Polish product and Bulgarian were observed. The committed effective dose of 137 Cs by annually drinking a cup of herb tea in adults was estimated to be about 1.0 x 10 -3 mSv and the contribution of 137 Cs is proved to be very small in this study.

    Full Text Available This study aimed to estimate the watershed runoff caused by extreme events that often result in the flooding of urban areas. The runoff of a residential area in the city of Guaratinguetá, São Paulo, Brazil was estimated using the Curve-Number method proposed by USDA-NRCS. The study also investigated current land use and land cover conditions, impermeable areas with pasture and indications of the reforestation of those areas. Maps and satellite images of Residential Riverside I Neighborhood were used to characterize the area. In addition to characterizing land use and land cover, the definition of the soil type infiltration capacity, the maximum local rainfall, and the type and quality of the drainage system were also investigated. The study showed that this neighborhood, developed in 1974, has an area of 792,700 m², a population of 1361 inhabitants, and a sloping area covered with degraded pasture (Guaratinguetá-Piagui Peak located in front of the residential area. The residential area is located in a flat area near the Paraiba do Sul River, and has a poor drainage system with concrete pipes, mostly 0.60 m in diameter, with several openings that capture water and sediments from the adjacent sloping area. The Low Impact Development (LID system appears to be a viable solution for this neighborhood drainage system. It can be concluded that the drainage system of the Guaratinguetá Riverside I Neighborhood has all of the conditions and characteristics that make it suitable for the implementation of a low impact urban drainage system. Reforestation of Guaratinguetá-Piagui Peak can reduce the basin’s runoff by 50% and minimize flooding problems in the Beira Rio neighborhood.

  13. Tech Area II: A history

    Energy Technology Data Exchange (ETDEWEB)

    Ullrich, R. [Ktech Corp., Albuquerque, NM (United States)

    1998-07-01

    This report documents the history of the major buildings in Sandia National Laboratories` Technical Area II. It was prepared in support of the Department of Energy`s compliance with Section 106 of the National Historic Preservation Act. Technical Area II was designed and constructed in 1948 specifically for the final assembly of the non-nuclear components of nuclear weapons, and was the primary site conducting such assembly until 1952. Both the architecture and location of the oldest buildings in the area reflect their original purpose. Assembly activities continued in Area II from 1952 to 1957, but the major responsibility for this work shifted to other sites in the Atomic Energy Commission`s integrated contractor complex. Gradually, additional buildings were constructed and the original buildings were modified. After 1960, the Area`s primary purpose was the research and testing of high-explosive components for nuclear weapons. In 1994, Sandia constructed new facilities for work on high-explosive components outside of the original Area II diamond-shaped parcel. Most of the buildings in the area are vacant and Sandia has no plans to use them. They are proposed for decontamination and demolition as funding becomes available.

    Non-methane hydrocarbons (NMHCs) are known to have an important role on air quality due to their high reactivity. NMHC analysis has been performed on 148 ambient air samples collected at five different sites in the Kanto area (Tokyo metropolitan area and surrounding six prefectures) of Japan in summer and winter of 2008, and fifty NMHCs have been determined and quantified. A field measurement campaign has been conducted at one of the busiest intersections in Tokyo metropolitan area in winter of 2008. NMHC emissions are evaluated through comparison of distributions of individual NMHCs emitted from motor vehicles, which are estimated from the measurements, with those determined from the current emissions inventory. The comparison revealed that the measured distributions of acetylene, ethylene and toluene showed a good agreement with those estimated from the emissions inventory (the values estimated from the measurements are a factor of 1.5, 0.56 and 2.3 larger than the emissions inventory in median, respectively), however, propane and isobutane are found to be significantly underestimated in the emissions inventory (the measured values were a factor of 18 and 5.1 larger than the emissions inventory, respectively). The significant underestimate of propane can be explained by that the current emissions inventory does not consider emissions from liquefied propane gas (LPG) fueled vehicles. However, for isobutane, reasons for the underestimate are still unclear. Another field measurement has been conducted in summer of 2008, where the air samples have been collected at three different sites on the ground and by a helicopter as well. Remarkable high concentrations of 1-butene and cis- and trans-2-butenes have been sporadically observed in the samples collected at Urayasu in the coastal area of Tokyo bay. Calculated propylene equivalent (PE) concentrations of butenes revealed that those have a significantly important role in ozone formation when the air plume is affected

  20. Selection of material balance areas and item control areas

    International Nuclear Information System (INIS)

    1975-04-01

    Section 70.58, ''Fundamental Nuclear Material Controls,'' of 10 CFR Part 70, ''Special Nuclear Material,'' requires certain licensees authorized to possess more than one effective kilogram of special nuclear material to establish Material Balance Areas (MBAs) or Item Control Areas (ICAs) for the physical and administrative control of nuclear materials. This section requires that: (1) each MBA be an identifiable physical area such that the quantity of nuclear material being moved into or out of the MBA is represented by a measured value; (2) the number of MBAs be sufficient to localize nuclear material losses or thefts and identify the mechanisms; (3) the custody of all nuclear material within an MBA or ICA be the responsibility of a single designated individual; and (4) ICAs be established according to the same criteria as MBAs except that control into and out of such areas would be by item identity and count for previously determined special nuclear material quantities, the validity of which must be ensured by tamper-safing unless the items are sealed sources. This guide describes bases acceptable to the NRC staff for the selection of material balance areas and item control areas. (U.S.)

    The Tono Geoscience Center is carrying out the Mizunami Underground Research Laboratory Project (MIU Project), as part of its scientific research program, in Mizunami City, Gifu Prefecture. We believe that the public and especially the local residents should have a precise understanding of the MIU project. Therefore, to provide information we have used virtual reality (VR) technology in the project since 1996. Software to introduce both the MIU Project and the geology of the Tono district has been completed. The Tono district is characterized by uranium ore deposits, and by clay deposits which are used by the pottery industry. Software with some amusement value, such as hot spring drilling, has also been completed. We plan further software development of VR technology to increase the feeling of realism. (author)

    Slack, John F.; Bitar, Richard F.

    1984-01-01

    On the basis of mineral-resource survey the Bread Loaf Roadless Area, Vermont, is considered to have probable resource potential for the occurrence of volcanogenic massive sulfide deposits of copper, zinc, and lead, particularly in the north and northeastern section of the roadless area. Nonmetallic commodities include minor deposits of sand and gravel, and abundant rock suitable for crushing. However, large amounts of these materials in more accessible locations are available outside the roadless area. A possibility exists that oil or natural gas resources may be present at great depth.
