    Several studies of sex differences in lung cancer survival have been reported. However, large-size population-based studies based on long-term observation are scarce. We investigated long-term trends in sex differences in lung cancer survival using population-based cancer registry data from Osaka, Japan. We analyzed 79 330 cases from the Osaka Cancer Registry (OCR) diagnosed between 1975 and 2007. We calculated 5-year relative survival in the six periods (1975-1980, 1981-1986, 1987-1992, 1993-1997, 1998-2002 and 2003-2007). To estimate the trends in sex differences in lung cancer survival throughout the study period, we applied a multivariate excess hazard model to control for confounders. The proportion of adenocarcinoma (ADC) and 5-year relative relative survival have increased for both sexes. Sex differences in lung cancer survival have widened over the period, especially in ADC and since the late 1990s. The excess hazard ratio of death within 5 years for males was 1.19 (95% CI: 1.16-1.21), adjusting for period at diagnosis, histologic type, stage, age group and treatment. We reported that females have better prognosis in lung cancer than males and the sex differences in lung cancer survival have become wider in Osaka, Japan. This can be partly explained by the sex differences in the proportions of histologic type and stage. Further studies considering other factors that influence sex differences in lung cancer survival are needed. © The Author 2017. Published by Oxford University Press. All rights reserved.

    Perfluoroalkyl acids (PFAAs) including perfluoroalkyl sulfonates (PFSAs) and perfluoroalkyl carboxylates (PFCAs) were analyzed in sediment samples taken from Ajifu Waterway in Osaka city, from Osaka Bay, and from Kagoshima Bay, as well as in fifteen seawater samples collected from Osaka Bay and coastal waters of Western Japan. In all sediment samples, only PFCAs were detected, and the highest concentration was determined in Ajifu Waterway, where ΣPFAA was 58990 ng kg -1 dry weight. The total concentrations of PFAAs in sea water samples ranged between the limit of quantification and 53.4 ng L -1 , and perfluorohexanoic acid was the most prevalent and had the highest concentration of 37 ng L -1 . The changes in the patterns and concentrations of PFAAs in Osaka Bay and coastal waters of Western Japan indicate that the PFAAs in surface waters are influenced by sources from Keihanshin Metropolitan Area, mainly the Yodo River basin, and the dilution effect which naturally occurs during their transport to the Pacific Ocean.

    The Great East Japan Earthquake occurred on March 11, 2011. Tokyo and Osaka, which are located 375 km and 750 km, respectively, from the epicenter, experienced tremors of 5.0 lower and 3.0 seismic intensity on the Japan Meteorological Agency scale. The Great East Japan Earthquake was the fourth largest earthquake in the world and was accompanied by a radioactive leak at a nuclear power plant and a tsunami. In the aftermath of a disaster, some affected individuals presented to mental health facilities with acute stress disorder (ASD) and/or post-traumatic stress disorder (PTSD). However, few studies have addressed mental stress problems other than ASD or PTSD among the general public immediately after a disaster. Further, the effects of such a disaster on residents living at considerable distances from the most severely affected area have not been examined. This study aimed to prospectively analyze the effect of a major earthquake on the prevalence of insomnia among residents of Tokyo and Osaka. A prospective online questionnaire study was conducted in Tokyo and Osaka from January 20 to April 30, 2011. An Internet-based questionnaire, intended to be completed daily for a period of 101 days, was used to collect the data. All of the study participants lived in Tokyo or Osaka and were Consumers' Co-operative Union (CO-OP) members who used an Internet-based food-ordering system. The presence or absence of insomnia was determined before and after the earthquake. These data were compared after stratification for the region and participants' age. Multivariate analyses were conducted using logistic regression and a generalized estimating equation. This study was conducted with the assistance of the Japanese CO-OP. The prevalence of insomnia among adults and minors in Tokyo and adults in Osaka increased significantly after the earthquake. No such increase was observed among minors in Osaka. The overall adjusted odds ratios for the risk of insomnia post-earthquake versus pre

    The distributions of 15 nitrated polycyclic aromatic hydrocarbons (NPAHs) in sediments collected at 44 sites throughout Osaka Bay, Japan were examined. The highest total NPAHs, with a concentration of 1949ng/kg dry weight, were detected near the city of Amagasaki. Some sites near the cities of Osaka, Kishiwada, sand Sakai registered ng/kg levels of NPAHs, but individual NPAH concentrations were relatively lower than those in previous studies. The sources were estimated using principal component analysis, and NPAHs were derived from exhaust gases of automobiles and industries at some sites. However, our results suggest that it is difficult to estimate the source, especially in coastal areas near big cities and large industrial areas, because the generation pathways between parent polycyclic aromatic hydrocarbons (PAHs) and nitrated PAHs are slightly different, and the ratio of PAHs and NPAHs could not be accurately reflect the characters of sources in sediments especially at coastal areas with large-scale industrial zones.

    Full Text Available It is well known that the aerosol distribution in Asia is complex due to both the increasing emissions of the anthropogenic aerosols associated with economic growth and the behavior of natural dusts. Therefore, detailed observations of atmospheric particles in Asian urban cities are important. In this work, we focus on the spatial and temporal variations of atmospheric particles around Higashi-Osaka in Japan. Higashi-Osaka is located in the eastern part of Osaka, the second-largest city in Japan, and is famous for small- and medium-sized manufacturing enterprises. For this study, we placed various ground measurement devices around the Higashi-Osaka campus of Kinki University including a Cimel sunphotometer supported by NASA/AERONET (Aerosol robotics network, suspended particulate matter (SPM sampler and LIDAR (light detection and ranging. Individual particle analyses with a SEM (scanning electron microscope/EDX (energy-dispersive X-ray analyzer show the temporal variations of particle properties, such as size, shape and components, during a dust event on 21 March 2010. The simultaneous measurement using a portable sun photometer with AERONET was conducted from April to November 2011. A comparison of the data at each site and the combination of the observed LIDAR data and model simulations indicate the difference in the transportation processes between dust and anthropogenic particles. We suppose this difference is attributed to the differences in the vertical aerosol profiles, where one aerosol is transported over Mount Ikoma and the other is blocked by it.

    Contaminations in sediments by polycyclic aromatic hydrocarbons (PAHs) and alkylated PAHs were investigated at 44 sites in Osaka Bay, Japan. Concentrations of total PAHs and alkylated PAHs were in the range 6.40-7800 ng/g dry weights and 13.7-1700 ng/g dry weights, respectively. The PAH concentrations tended to be higher along the shoreline in the vicinities of big ports, industrialized areas, and densely populated regions such as the cities of Osaka and Kobe. The major sources appeared to be pyrogenic or both pyrogenic and petrogenic at most of the sites. PAH concentrations were remarkably high at a site near Kobe, where the concentrations of dibenzo(a,h)anthracene and benzo(g,h,i)perylene exceeded the effects-range-medium concentration and eight PAHs were above the corresponding effects-range-low concentrations. Those PAHs may have been derived from the great fire associated with the large earthquake in 1995. Copyright © 2014 Elsevier Ltd. All rights reserved.

    "Radiation Fair" has been held in summer vacation season in August for more than 10 years in Osaka, the largest city of western Japan, for the purpose of public education and information transfer of radiation and radiation-related technology. We distributed questionnaires to the visitors for recent 3 years to inquire their status toward radiation and irradiated products including irradiated potatoes as well as impression toward the displays. According to the survey results, more than 60% of the kids visitors were satisfied with this exhibition as informative, more than half of the older visitors (16 years old and upward) indicated that they recognized the word of "radiation" when they were at elementary school and the most significant sources of this information were school lessons and the mass media. Consumer's image toward radiation seems to shift to more "positive" when correct knowledge about radiation is given. More than half of consumers did not know "irradiated potatoes" but the percentage indicating that irradiated potatoes was definitely hazardous was less than 10%.

    Radon concentrations in outdoor air at 18 sites in the Osaka district, in the central part of Japan's main island, were measured with electrostatic integrating radon monitors which were developed by Y Ikebe et al of the Osaka survey centre as part of a nationwide survey of radon indoors and outdoors in Japan conducted by the National Institute of Radiological Science. The mean radon concentration in outdoor air during 2-month periods was measured over a period of a year and a half. In addition, the absorbed dose rate in air and the concentration of natural radionuclides in soil were measured at 40 sites in Osaka Prefecture which is located in the central part of the Osaka district using thermoluminescence dosemeters and with gamma ray spectrometry, respectively. Radon concentration in outdoor air showed a seasonal pattern, reaching its maximum during the winter and its minimum during the summer, but this variation was not significant at the coastal sites. It was concluded that this variation is correlated with a seasonal wind which blows from the continental interior to the ocean in winter and in the opposite direction in summer, as well as with geographical factors. Radon concentration in outdoor air in the Osaka district ranged from 0.6 to 17.9 Bq.m -3 and mean annual radon concentration in outdoor air at the 18 sites ranged from 2.7 to 6.9 Bq.m -3 . It was discovered that radon concentration in outdoor air decreased with wind speed in both winter and summer. The absorbed dose rate in air ranged from 66 to 114 nGy.h -1 , and the concentration of 226 Ra in soil ranged from 20 to 60 Bq.kg -1 respectively. (author)

    The use of alcohol fuel has received much attention since the 1980s. In Brazil, ethanol-fuelled vehicles have been currently used on a large scale. This paper reports the atmospheric methanol and isoproponal concentrations which were measured from May to December 1997, in Osaka, Japan, where alcohol fuel was not used and from 3 to 9 February 1998 in Sao Paulo, Brazil, where ethanol was used. The alcohols were determined by the alkyl nitrite formation reaction using gas chromatography (GC-ECD) analysis. The concentration of atmospheric alcohols, especially ethanol, measured in Sao Paulo were significantly higher than those in Osaka. In Osaka, the average concentrations of atmospheric methanol, ethanol, and isopropanol were 5.8 ± 3.8, 8.2 ± 4.6, and 7.2 ± 5.9ppbv, respectively. The average ambient levels of methanol, ethanol, and isopropanol measured in Sao Paulo were 34.1± 9.2, 176.3 ± 38.1, and 44.2 ± 13.7ppbv, respectively. The ambient levels of aldehydes, which were expected to be high due to the use of alcohol fuel, were also measured at these sampling sites. The atmospheric formaldehyde average measured in Osaka was 1.9± 0.9ppbv, and the average acetaldehyde concentration was 1.5 ± 0.8ppbv. The atmospheric formaldehyde and acetaldehyde average concentrations measured in Sao Paulo were 5.0 ± 2.8 and 5.4 ± 2.8ppbv, respectively. The C 2 H 5 OH/CH 3 OH and CH 3 CHO/HCHO were compared between the two measurement sites and elsewhere in the world, which have already been reported in the literature. Due to the use of ethanol-fuelled vehicles, these ratios, especially C-2H 5 OH/CH 3 OH, are much higher in Brazil than those measured elsewhere in the world. (Author)

    'Youngster's Science Festival' has been held in several big cities in various districts in Japan for the purpose of induction of young students' interests in science and scientific experiments. On the basis of the survey results from the participants of the 'Radiation Fair' in Osaka, Japan, which was presented at the last IMRP, we expanded the area of survey and distributed questionnaires to the visitors of the above event to inquire their status toward radiation and irradiated products including irradiated potatoes. The survey results indicated the same trends as that of the 'Radiation Fair' survey. That is, more than half of the older visitors (16 years old and upward) indicated that they recognized the word of 'radiation' when they were at elementary school and the most significant sources of this information were school lessons and the mass media. We will discuss the relationship between consumer's image toward radiation and the description of radiation related topic in school textbooks. (author)

    The survival gap between adolescents and young adults (AYAs) with hematological malignancies persists in many countries. To determine to what extent it does in Japan, we investigated survival and treatment regimens in 211 Japanese AYAs (15-29 years) in the Osaka Cancer Registry diagnosed during 2001-2005 with hematological malignancies, and compared adolescents (15-19 years) with young adults (20-29 years). AYAs with acute lymphoblastic leukemia (ALL) had a poor 5-year survival (44%), particularly young adults (29% vs. 64% in adolescents, p = 0.01). Additional investigation for patients with ALL revealed that only 19% of young adults were treated with pediatric treatment regimens compared with 45% of adolescents (p = 0.05). Our data indicate that we need to focus on young adults with ALL and to consider establishing appropriate cancer care system and guidelines for them in Japan.

    This study presents the results of a total diet study performed for estimating the dietary intake of polybrominated diphenyl ethers (PBDEs) in Osaka, Japan. The concentrations of 36 PBDEs were measured in samples from 14 food groups (Groups I-XIV). PBDEs were detected only in Groups IV (oils and fats), V (legumes and their products), X (fish, shellfish, and their products), and XI (meat and eggs) at concentrations of 1.8, 0.03, 0.48, and 0.01 ng g⁻¹, respectively. For an average person, the lower bound dietary intakes of penta- and deca-formulations were estimated to be 46 and 21 ng day⁻¹, respectively. A high proportion of the decabrominated congener (DeBDE-209) was observed in Group IV. To confirm the presence of DeBDE-209 in vegetable oils, an additional analysis was performed using 18 vegetable oil samples. Of these, seven contained ng g⁻¹ levels of DeBDE-209.

    With a broader aim of controlling pulmonary tuberculosis (TB) among foreigners, here, we have reported the findings of chest radiography screening for TB among international students at Japanese language schools in Osaka city. Between April 2011 and December 2013, 4,529 international students from 19 Japanese language schools in Osaka city underwent chest radiography for TB screening. The chest radiographs were studied in reference to the student's sex, age, nationality, and date of entry to Japan as well as any health conditions present at the time of screening. We further analyzed the bacterial information and pulmonary TB classification based on chest radiography findings of students who were identified to be positive for TB. Information on the implementation of health education was also gathered. The results revealed that 52.5% of the students who underwent chest radiography came from China, 20.3 % from South Korea, and 16.3% from Vietnam. Of the students, 52.9% were male and 47.1% were female. The median age of students was 23 years (range: 14-70 years). The median number of days from the first date of entry to Japan up until the radiography screening was 63 days. Based on the chest radiography findings, 71 students (1.6%) were suspected to have TB; however, further detailed examination confirmed that 19 students (0.4%) had active TB. This percentage is significantly higher than the 0.1% TB identification rate among residents in Osaka city of the same time period (Pschools (for a total of 12 times) in the 3-year period. A total of 257 language school staff and students attended the health education seminars. The identification rate of TB positive students in Japanese language schools was higher than that of the general residents in Osaka city. In addition, most of these students came to Japan within 1 year. It is also important to note that the majority of TB positive students had sputum smear negative results. This study proves that medical examination after

    We have been successfully operating 'Radiation Fair--The relationship between daily life and radiation--' during summer vacation season in August every year for 15 years in Osaka, the largest city of western Japan. The purpose of this event is radiation education of public including school kids through efficient information transfer of radiation and radiation-related technology. Currently we set up the space of it on a floor of Kintetsu Department Store, one of the major department stores in downtown Osaka and display various irradiated products available in our daily life together with explanatory panels. We have been devising various attractions as efficient information transfer media so that even elementary-school kids understand the basic knowledge of radiation and irradiation technologies. The number of participants has increased year by year until more than 20,000 in recent years. We distributed questionnaires to the visitors for recent 3 years to inquire their status toward radiation and irradiated products as well as impression toward the displays. The survey results suggest that school education may contribute to establish the public image toward 'radiation' as well as mass media. (author)

    To investigate and control an outbreak of bloodstream infections (BSIs) caused by Serratia marcescens and to identify risk factors for respiratory colonization or infection with S. marcescens. Epidemiologic investigation, including review of medical and laboratory records, procedural investigations, pulsed-field gel electrophoresis (PFGE) typing of environmental and patient isolates, statistical study, and recommendation of control measures. All patients admitted to a 380-bed, secondary-care hospital in Osaka Prefecture, Japan, from July 1999 through June 2000 (study period). Seventy-one patients were colonized or infected with S. marcescens; 3 patients who developed primary BSIs on the same ward within 5 days in June 2000 had isolates with indistinguishable PFGE patterns and indwelling intravenous catheters for more than 5 days. On multivariate analysis, among 36 case-patients with positive sputum specimens and 95 control-patients, being bedridden (odds ratio [OR], 15.91; 95% confidence interval [CI95], 4.17-60.77), receiving mechanical ventilation (OR, 7.86; CI95, 2.27-27.16), being older than 80 years (OR, 3.12; CI95, 1.05-9.27), and receiving oral cleaning care (OR, 3.10; CI95, 1-9.58) were significant risk factors. S. marcescens was isolated from the fluid tanks of three nebulizers and a liquid soap dispenser. The hospital did not have written infection control standards, and many infection control practices were found to be inadequate (eg, respiratory equipment was used without disinfection between patients). Poor hospital hygiene and the lack of standard infection control measures contributed to infections hospital-wide. Recommendations to the hospital included adoption of written infection control policies.

    A calculation method is proposed for the fission-track ages of zircon crystals in volcanic material. In this method, it is checked whether the spontaneous fission-track number of respective zircon crystals follows the Poisson distribution. If it does, the age is calculated by population method with all crystals, and if not, only with those crystals following the Poisson distribution, eliminating abnormal crystals. Extraneous zircon crystals are thus excluded and crystals with spontaneous fission-track number zero are not ignored. The following ages were obtained: Tamateyama volcanic ash in the Nijo group, 14.0 +- 0.6 Ma; pink volcanic ash in the Osaka group, 1.0 +- 0.2 Ma; Matsuo volcanic ash in the Ko-Osaka group, 1.5 +- 0.4 Ma; pumice volcanic ash in the Ko-Osaka group, 2.3 +- 0.4 Ma; Asashiro volcanic ash in the Ko-Osaka group, 2.9 +- 0.6 Ma.

    Traditionally, Japan has been regarded as a country with low crime. Comparative research has given insights into the extent of similarities and differences in crime between America and Japan. The importance of these studies is the examination of whether Western-established criminological knowledge is applicable to non- Western societies like Japan. Unfortunately, comparative self-report studies involving Japan and investigating youth offending are scarce. The current study investigates risk factors and self-reports of violence from Osaka and Seattle male youths. The findings reveal that Japanese male youths self-report a higher prevalence of violence than Seattle male youths. Risk factors for violence, issues of comparability, and prevalence versus strength of relationships of risk factors are examined. It is concluded that the higher prevalence of violence in Osaka is primarily a function of the higher prevalence of troubled peers and risk taking. The findings call for replication of this type of comparative research. PMID:24013769

    Marine traffic in Osaka Bay is very intensified and much atmosphere pollutant (SO x and NO x ) from ships is released but there is no regulation about the ship emission. In this paper, we investigated the emission amounts of SO x NO x and HC from car, factory and ships in Osaka bay area and estimated the influence of the ship emission on the atmospheric pollutant concentration, using both the meteorological prediction model and the atmospheric pollutant concentration prediction model including the dry deposition and the chemical reaction. In Osaka bay area, the emission amounts of SO x and NO x from ships were about 30% of the total emission amounts, respectively. Using these emission data, the atmospheric pollutant concentration was simulated on a summer fine day when high oxidant concentration was measured at several observatories and was compared with the observed data. Though some differences were seen between the simulated results and the observed data, the diurnal variation agreed reasonably. The second simulation was carried out except for the ship emission and we estimated the influence of the ship emission on the atmospheric pollutant concentration. It was found that the ship emission raised SO 2 , NO 2 and NO concentration not only in shore area but also in 40km inland. (Author)

    The levels and distribution of 55 volatile organic compounds (VOCs) were determined by purge and trap GC-MS on water samples from 30 sites within the urban rivers and estuaries of Osaka, a populated industrialized city of Japan. Forty of 55 target VOCs listed in the US EPA Method 524.2 were detected. Dichloromethane (DCM) was found at higher levels at all of the sampling sites. The distribution of dominant VOCs followed four different patterns. First, the most common VOCs (DCM, toluene, trichloroethene and tetrachloroethene) showed concentration maxima in the river segments, and the sites of maximum concentration fluctuated due to irregular large spills and/or loadings. Second, one VOC (cis-1,2-dichloroethene) was evenly distributed in particular rivers due to fixed loadings. Both of these patterns were found in the upper and middle reaches. Third, some of VOCs (1,2,3-trichloropropane and benzene) were specific to a single industrial site and truceable to those sources. Finally, some VOCs showed no concentration maxima along the rivers and entered from multiple sources (chloroform and bromodichloromethane). Diurnal variations of VOCs at the border of the city area, receiving domestic and industrial discharges, provided information to interpret their observed downstream distribution and possible sources.

    The Cybermedia Center (CMC), Osaka University, is a research institution that offers knowledge and technology resources obtained from advanced researches in the areas of large-scale computation, information and communication, multimedia content and education. Currently, CMC is involved in Japanese national Grid projects such as JGN II (Japan Gigabit Network), NAREGI and BioGrid. Not limited to Japan, CMC also actively takes part in international activities such as PRAGMA. In these projects and international collaborations, CMC has developed a Grid system that allows scientists to perform their analysis by remote-controlling the world's largest ultra-high voltage electron microscope located in Osaka University. In another undertaking, CMC has assumed a leadership role in BioGrid by sharing its experiences and knowledge on the system development for the area of biology. In this paper, we will give an overview of the BioGrid project and introduce the progress of the Telescience unit, which collaborates with the Telescience Project led by the National Center for Microscopy and Imaging Research (NCMIR). Furthermore, CMC collaborates with seven Computing Centers in Japan, NAREGI and National Institute of Informatics to deploy PKI base authentication infrastructure. The current status of this project and future collaboration with Grid Projects will be delineated in this paper.

    Anthropogenic effects in both Osaka and Bangkok were evaluated to compare the relationships between subsurface environment and the development stage of both cities. Subsurface thermal anomalies due to heat island effects were found in both cities. The Surface Warming Index (SWI), the departure depth from the steady geothermal gradient, was used as an indicator of the heat island effect. SWI increases (deeper) with the magnitude of heat island effect and the elapsed time starting from the surface warming. Distributions of subsurface thermal anomalies due to the heat island effect agreed well with the distribution of changes in air temperature due to the same process, which is described by the distribution of population density in both Osaka and Bangkok. Different time lags between groundwater depression and subsidence in the two cities was found. This is attributed to differences in hydrogeologic characters, such as porosity and hydraulic conductivity. We find that differences in subsurface degradations in Osaka and Bangkok, including subsurface thermal anomalies, groundwater depression, and land subsidence, depends on the difference of the development stage of urbanization and hydrogeological characters.

    Although it is important to assess the factors associated with traffic accident fatalities to decrease them as a matter of public health, such factors have not been fully identified. Using a large-scale data set of ambulance records in Osaka City, Japan, we retrospectively analyzed all traffic accident patients transported to hospitals by emergency medical service personnel from 2013 to 2014. In this study, prehospital death was defined as that occurring at the scene or in the emergency department immediately after hospital arrival. We assessed prehospital factors associated with prehospital death due to traffic accidents by logistic regression models. This study enrolled 28,903 emergency patients involved in traffic accidents, of whom 68 died prehospital. In a multivariate model, elderly patients aged ≥75 years (adjusted odds ratio [AOR] = 4.34; 95% confidence interval [CI], 2.29-8.23), nighttime (AOR = 2.75; 95% CI, 1.65-4.70), and type of injured person compared to bicyclists such as pedestrians (AOR = 9.58; 95% CI, 5.07-17.99), motorcyclists (AOR = 2.75; 95% CI, 1.21-6.24), and car occupants (AOR = 2.98; 95% CI, 1.39-6.40) were significantly associated with prehospital death due to traffic accidents. In addition, the AOR for automobile versus nonautomobile as the collision opponent was 4.76 (95% CI, 2.30-9.88). In this population, the factors associated with prehospital death due to traffic accidents were elderly people, nighttime, and pedestrian as the type of patient. The proportion of prehospital deaths due to traffic accidents was also high when the collision component was an automobile.

    Large amplitude long-period ground motions (1-10s) with long duration were observed in the Osaka sedimentary basin during the 2011 Tohoku earthquake (Mw9.0) and its aftershock (Ibaraki-Oki, Mw7.7), which is about 600 km away from the source regions. Sato et al. (2013) analyzed strong ground motion records from the source region to the Osaka basin and showed the following characteristics. (1) In the period range of 1 to 10s, the amplitude of horizontal components of the ground motion at the site-specific period is amplified in the Osaka basin sites. The predominant period is about 7s in the bay area where the largest pSv were observed. (2) The velocity Fourier amplitude spectra with their predominant period of around 7s are observed at the bedrock sites surrounding the Osaka basin. Those characteristics were observed during both of the mainshock and the largest aftershock. Therefore, large long-period ground motions in the Osaka basin are generated by the combination of propagation-path and basin effects. They simulated ground motions due to the largest aftershock as a simple point source model using three-dimensional FDM (GMS; Aoi and Fujiwara, 1999). They used a three-dimensional velocity structure based on the Japan Integrated Velocity Structure Model (JIVSM, Koketsu et al., 2012), with the minimum effective period of the computation of 3s. Their simulation result reproduced the observation characteristics well and it validates the applicability of the JIVSM for the long period ground motion simulation. In this study, we try to simulate long-period ground motions during the mainshock. The source model we used for the simulation is based on the SMGA model obtained by Asano and Iwata (2012). We succeed to simulate long-period ground motion propagation from Kanto area to the Osaka basin fairly well. The long-period ground motion simulations with the several Osaka basin velocity structure models are done for improving the model applicability. We used strong motion

    Restructuring was carried out on a sedimentary basin structure model of the Osaka plain including Osaka Bay by using newly obtained underground structural data. After the Hygoken-nanbu Earthquake of 1995, a large number of underground structure investigations have been performed in Osaka Bay and urban areas of Kobe and Osaka. However, very few surveys have been done in areas peripheral to Osaka Prefecture, such as the Ikoma area. Therefore, an attempt has been made to increase the number of measuring points to acquire underground structural data of these areas. Estimation of basic rock depths has utilized the dominant cycles in H/V spectra obtained from micro vibration survey, and good correlation of the base rock depths derived by a refraction exploration and a deep-bed boring investigation. With regard to bed division and P- and S- wave velocities in sedimentary beds in the Osaka sedimentary basin, an underground structure model was prepared, which was divided into four beds according to the refraction exploration and the micro vibration investigation. Data obtained by using this model agreed well with depth data acquired from physical exploration and other types of investigations. However, no good agreement was recognized in the data for such areas where the basic depth changes abruptly as the Rokko fault and the Osaka bay fault. 6 refs., 8 figs., 2 tabs.

    Although the prolongation of the time between injury and hospital arrival of traffic accident patients can influence their prognosis, factors associated with the difficulty in hospital acceptance of these patients have not been sufficiently evaluated in Japan. We retrospectively analyzed the population-based ambulance records of all traffic accident patients for whom the Osaka Municipal Fire Department (Osaka City, Japan) dispatched an ambulance in 2013. We defined "cases with difficulty in hospital acceptance" as cases that required ≥4 calls by emergency medical service personnel at the scene before receiving hospital acceptance. We included patient characteristics (age, sex, coma status, and trauma severity judged by emergency medical service personnel), time factors (day/night or weekday/holiday and weekends), and accident location for multivariable logistic regression analysis to assess factors associated with the difficulty in hospital acceptance. Among 13,427 traffic accident patients, 2,033 (15.1%) were cases with difficulty in hospital acceptance. Pediatric patients (adjusted odds ratio [OR], 1.265; 95% confidence interval [CI], 1.060-1.509), male sex (adjusted OR, 1.260; 95% CI, 1.135-1.398), moderate-grade trauma (adjusted OR, 2.241; 95% CI, 1.972-2.547), severe-grade trauma (adjusted OR, 2.057; 95% CI, 1.249-3.388), holidays and weekends (adjusted OR, 1.702; 95% CI, 1.539-1.882), and night-time (adjusted OR, 2.720; 95% CI, 2.443-3.027) were positively associated with difficulty in hospital acceptance. Using population-based ambulance records from a large urban community in Japan, we showed that the difficulty in hospital acceptance of patients at the scene of traffic accidents was positively associated with several prehospital factors.

    We aimed to investigate prehospital factors associated with difficulty in hospital acceptance among elderly emergency patients. We reviewed ambulance records in Osaka City from January 2013 through December 2014, and enrolled all elderly emergency patients aged ≥65 years who were transported by on-scene emergency medical service personnel to a hospital that the personnel had selected. The definition of difficulty in hospital acceptance was to the requirement for ≥4 phone calls to hospitals by emergency medical service personnel before receiving a decision from the destination hospitals. Prehospital factors associated with difficulty in hospital acceptance were examined through logistic regression analysis. During the study period, 72 105 elderly patients were included, and 13 332 patients (18.5%) experienced difficulty in hospital acceptance. In the simple linear regression model, hospital selection time increased significantly with an increasing number of phone calls (R 2  = 0.774). In the multivariable analysis, older age (P for trend emergency-related symptoms and difficulty in hospital acceptance among elderly patients with symptoms of internal disease (AOR 1.71, 95% CI 1.53-1.91). In Japan, which has a rapidly aging population, a comprehensive strategy for elderly emergency patients, especially for advanced age groups or nursing home residents, is required.

    The patient characteristics, pre-hospital interventions, and outcomes of out-of-hospital cardiac arrests (OHCA) occurring during exercise, have not been sufficiently investigated among the general population. OHCA data from 2009 to 2015 were obtained from the population-based OHCA registry in Osaka City, Japan. Patients who suffered OHCA, which occurred during exercise before the arrival of emergency medical service personnel, were included. The primary endpoint was one-month survival with a favourable neurological outcome after OHCA, defined using the Glasgow-Pittsburgh cerebral performance category scale 1 or 2. During the 7-year study period, 16,278 OHCAs were observed, and 52 (0.3%) occurred during exercise (male, n=41 [79%]; median age, 62 years). These incidents occurred mainly during running activities (n=14), followed by swimming (n=8), dance/social dance (n=6), tennis (n=4), and weight training (n=3). Within these exercise-related OHCAs, 47 (90%) were of cardiac origin, 45 (87%) were bystander-witnessed cardiac arrests, 49 (94%) received bystander-initiated cardiopulmonary resuscitation, and 30 (57%) received public-access defibrillation (PAD). Overall, 56% (29/52) had one-month survival with a favourable neurological outcome after OHCA, which was significantly higher among OHCAs of cardiac origin with PAD (77%, 23/30) than among those of cardiac origin without PAD (35%, 6/17) and among those of non-cardiac origin (0%, 0/5) (pexercise represented a small subset of the overall OHCA burden, but occurred during a wide variety of exercise activities. Patients with OHCA of cardiac origin had a good prognosis, and PAD played an important role in improving patient outcomes. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available 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 < 0.001, indicated that increased awareness and use of PEP might have prevented disease. 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

    To investigate the time variations of radionuclides discharged from the Fukushima Daiichi nuclear power plants accident, we started collecting aerosol samples in Osaka, Japan, using a high-volume sampler from March 15 to May 1, 2011. Atmospheric radioactivity concentrations of I-131, Cs-134 and Cs-137 were measured with germanium semi-conductor detectors. Only I-131 was detected in the early phase and two Cs-134.137 peaks were found in Osaka in April. Using the HYSPLIT model, we concluded that direct transportation of the air mass from the Fukushima area was responsible for such events. (author)

    This report is a compilation of the research activities and operations of the Research Center For Nuclear Physics (RCNP), Osaka University, during the period of the academic year 1994, April 1994 to March 1995. RCNP is the national laboratory for nuclear physics in Japan. The AVF cyclotron with K = 0.14GeV and the ring cyclotron with K = 0.4GeV and E P = 0.4GeV are the major user facilities at RCNP. They have been extensively used for studying nuclear nucleon-meson systems. All facilities are open for users from universities and research institutes in Japan as well as those in foreign countries. The research activities at the RCNP cyclotron laboratory include studies of nuclear interactions and nuclear potentials, spin isospin excitations and decays nuclear reaction dynamics and others. Studies of solid state and atomic physics and medical applications were carried out also at the cyclotron laboratory. New external ion sources have been instaled for the injector cyclotron. New extensions of the RCNP research activities are under progress. One is the possible use of the 8 GeV electron storage ring built at the synchrotron radiation laboratory SPring-8. It is located 100 Km west of Osaka. It is expected to start its operation in 1997. The Compton back-scattering of laser photons from the 8 GeV electron beam provides 1-3.5 GeV γ-rays, which are very promising for studying nuclear quark and meson systems. Other is the non-accelerator physics for ultra-rare nuclear processes at the new under ground laboratory 'Ohto Cosmo Observatory'. It is located 100 km south of Osaka. Neutrino studies by investigating double beta decays, dark matter studies by investigating nuclear responses to them, and studies of other weak processes are planned to be studied there. (J.P.N.)

JEV is considered to be indigenized and widespread in Japan, whereas WNV and DenV are not indigenized in Japan. Globulin products seem to reflect the status of the donor population according to antivirus neutralization activity. However, the anti-JEV, -WNV, and -DenV neutralization activities of globulin products derived from donors in Japan have not been clarified. Furthermore, potential candidates for the development of an effective immunotherapeutic drug for encephalitis caused by JEV, WNV, or DenV have also not been identified. Therefore, the aim of this study was to determine the overall status of the donor population in Japan based on globulin products by evaluating anti-JEV, -WNV, and -DenV neutralizing activities of intravenous immunoglobulin. Overall, intravenous immunoglobulin products showed stable neutralizing activity against JEV but showed no or only weak activity against WNV or DenV. These results suggest that the epidemiological level against WNV and DenV in the donor population of Japan is still low, suggesting that these viruses are not yet indigenized. In addition, JEV vaccinations and/or infections in the donor population do not induce a cross-reactive antibody against WNV. Keywords

    After more than ten years of strategic investment research and development supported by government policies on science and technology, nanotechnology in Japan is making a transition from the knowledge creation stage of exploratory research to the stage of making the outcomes available for the benefit of society as a whole. Osaka University has been proactive in discussions about the relationship between nanotechnology and society as part of graduate and continuing education programs. These programs are intended to fulfill the social accountability obligation of scientists and corporations involved in R&D, and to deepen their understanding of the relationship between science and society. To meet those aims, the program has covered themes relating to overall public engagement relating to nanotechnology governance, such as risk management of nanomaterials, international standardization for nanotechnology, nanomeasurement, intellectual property management in an open innovation environment, and interactive communication with society. Nanotechnology is an emerging field of science and technology. This paper reports and comments on initiatives for public engagement on nanotechnology at Osaka University's Institute for NanoScience Design, which aims to create new technologies based on nanotechnology that can help realize a sustainable society.

  19. Verification and Improvement of the Three-Dimensional Basin Velocity Structure Model in the Osaka Sedimentary Basin, Japan Using Interstation Green's Functions and H/V Spectral Ratios of Microtremors

    The Osaka sedimentary basin is filled by the Plio-Pleistocene Osaka group, terrace deposits, and alluvium deposits with thickness of 1 to 2 km over the bedrock, and it is surrounded by active fault systems. The Uemachi active fault system underlies the Osaka urban area. In order to predict the strong ground motions for future events of the Uemachi fault and others, the precise basin velocity structure model is indispensable as well as the detailed source fault model. The velocity structure of the Osaka basin has been extensively investigated by using various techniques such as gravity anomaly measurements, reflection surveys, boring explorations, and microtremor measurements. Based on these surveys and ground motion simulations for observed events, the three-dimensional velocity structure models of the Osaka basin have been developed and improved for decades (e.g., Kagawa et al., 1993; Horikawa et al., 2003; Iwata et al., 2008; Iwaki and Iwata, 2011). Now we are trying to verify the velocity structure model of the Osaka basin and to improve it incorporating new data sets. We have conducted two kinds of observations in the Osaka basin. The first observation is continuous microtremor observation. We have temporarily installed three-component velocity sensors at 15 sites covering the Osaka basin to record microtremors continuously for more than one year. The seismic interferometry technique (e.g. Shapiro and Campillo, 2004) is applied to retrieve interstation Green's function for analyzing the wave propagation characteristics inside the sedimentary basin. Both Rayleigh- and Love-wave type signals are identified in 0.1-0.5 Hz from observed interstation Green's functions. The group velocities of Rayleigh and Love waves propagating between two stations are estimated from them using the multiple filter analysis method, and they are compared with the theoretical group-velocities of the model. For example, estimated Love-wave group velocity along a line inside the basin is

  20. Major Change in the Predominant Type of “Norwalk-Like Viruses” in Outbreaks of Acute Nonbacterial Gastroenteritis in Osaka City, Japan, between April 1996 and March 1999

    2000-01-01

    In Osaka City, Japan, between April 1996 and March 1999, a total of 350 fecal specimens from 64 outbreaks of acute nonbacterial gastroenteritis were examined to investigate infection by “Norwalk-like viruses” (NLVs). By reverse transcription (RT)-PCR, 182 samples (52.0%) from 47 outbreaks (73.4%) were NLV positive. During those three years, the incidence of NLV-associated outbreaks showed seasonality, being higher during January to March (winter to early spring). The ingestion of contaminated oysters was the most common transmission mode (42.6%). The amplicons of the 47 outbreak strains that were NLV positive by RT-PCR were tested using Southern hybridization with four probe sets (Ando et al., J. Clin. Microbiol. 33:64–71, 1995). Forty of the outbreak strains were classified as 4 probe 1-A (P1-A) strains, 6 P1-B strains, 10 P2-A strains, 17 P2-B strains, and 3 untypeable strains, and the other 7 outbreaks were determined to be mixed-probe-type strains. Probe typing and partial sequence analysis of the outbreak strains indicated that a predominant probe type of NLVs in Osaka City had drastically changed; P2-B strains (77.8%) with multiple genetic clusters were observed during the 1996–97 season, the P2-A common strain (81.3%) related to the Toronto virus cluster was observed during the 1997–98 season, and P1-B strains (75.0%) with a genetic similarity were observed during the 1998–99 season. For the three untypeable outbreak strains (96065, 97024, and 98026), the 98026 outbreak strain had Southampton virus (SOV)-like sequences, and each of the other outbreak strains had a unique 81-nucleotide sequence. Newly designed probes (SOV probe for the 98026 outbreak strain and the 96065 probe for the 96065 and 97024 outbreak strains) were hybridized with relative strains and without other probe type strains. The prevalent NLV probe types in Osaka City during those three years were classified in six phylogenetic groups: P1-A, P1-B, P2-A, P2-B, SOV, and 96065 probe

    Science.gov (United States)

    Watanabe, Takumi; Karasawa, Kaori

    2013-04-01

    This article examines the effects of language use on explicit and implicit attitudes. We employed the matched-guise technique to measure participants' impressions of standard-Japanese and Osaka-dialect speakers. Implicit attitudes were assessed by the Implicit Association Test (IAT). The Osaka-dialect speaker was evaluated as warmer than the standard-Japanese speaker, suggesting that explicit attitudes toward the Osaka dialect have changed positively. On the other hand, the results for the impression of intelligence were consistent with the previous literature that the standard-Japanese speaker was seen as more intelligent than the Osaka-dialect speaker. Compared with explicit attitudes, the analyses of implicit attitudes revealed that participants showed a consistent implicit bias favoring standard-Japanese language use. The changing processes and relationships of explicit and implicit attitudes were discussed.

  6. Liquid hydrogen in Japan

    Yasumi, S. [Iwatani Corp., Osaka (Japan). Dept. of Overseas Business Development

    2009-07-01

    Japan's Iwatani Corporation has focused its attention on hydrogen as the ultimate energy source in future. Unlike the United States, hydrogen use and delivery in liquid form is extremely limited in the European Union and in Japan. Iwatani Corporation broke through industry stereotypes by creating and building Hydro Edge Co. Ltd., Japan's largest liquid hydrogen plant. It was established in 2006 as a joint venture between Iwatani and Kansai Electric Power Group in Osaka. Hydro Edge is Japan's first combined liquid hydrogen and ASU plant, and is fully operational. Liquid oxygen, liquid nitrogen and liquid argon are separated from air using the cryogenic energy of liquefied natural gas fuel that is used for power generation. Liquid hydrogen is produced efficiently and simultaneously using liquid nitrogen. Approximately 12 times as much hydrogen in liquid form can be transported and supplied as pressurized hydrogen gas. This technology is a significant step forward in the dissemination and expansion of hydrogen in a hydrogen-based economy.

    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. -- Highlights: • High perfluorohexanoic acid concentration was detected in the Samondogawa River. • The mass flow rate of PFCs in this river section was 3900–29,000 kg/y. • Perfluorohexanoic acid was the dominant compound at all seawater sampling sites. • Perfluorohexanoic acid from the Samondogawa River may have affected Osaka Bay. -- Discharge of perfluorohexanoic acid from the Samondogawa River may have affected Osaka Bay

    Highlights: •We have benchmarked FENDL-3.0 with integral experiments with DT neutron sources in Japan. •The FENDL-3.0 is as accurate as FENDL-2.1 and JENDL-4.0 or more. •Some data in FENDL-3.0 may have some problems. -- Abstract: The IAEA supports and promotes the gathering of the best data from evaluated nuclear data libraries for each nucleus involved in fusion reactor applications and compiles these data as FENDL. In 2012, the IAEA released a major update to FENDL, FENDL-3.0, which extends the neutron energy range from 20 MeV to greater than 60 MeV for 180 nuclei. We have benchmarked FENDL-3.0 versus in situ and TOF experiments using the DT neutron source at FNS at the JAEA and TOF experiments using the DT neutron source at OKTAVIAN at Osaka University in Japan. The Monte Carlo code MCNP-5 and the ACE file of FENDL-3.0 supplied from the IAEA were used for the calculations. The results were compared with measured ones and those obtained using the previous version, FENDL-2.1, and the latest version, JENDL-4.0. It is concluded that FENDL-3.0 is as accurate as or more so than FENDL-2.1 and JENDL-4.0, although some data in FENDL-3.0 may be problematic

A questionnaire-based interview elicited details concerning mental and somatic symptoms in patients visiting a psychosomatic clinic in Japan. Univariate logistic regression analyses followed by multiple regression models using a stepwise method were selected for identifying the candidate symptoms. Overall, symptoms related to depression were associated with SI in both sexes. Although women showed more various somatic symptoms associated with SI than men, many of those associations were diminished once severity of the depression was controlled. The current results suggest that a variety of self-reported symptoms, mainly related to depression, might reveal suicidal risk in outpatients with an urban hospital clinical setting.Keywords: suicidal ideation, psychosomatic clinic, subjective symptoms

Dementia is a major brain disease among elderly people, and is caused by cognitive impairment. The locomotive syndrome (LS refers to a condition in which people require healthcare services because of problems associated with locomotion. The purpose of this study was to determine the association between cognitive impairment and LS. Study participants were 142 healthy elderly female volunteers living in a rural area in Japan. Cognitive function was assessed using the Mini-Mental State Examination (MMSE. A score of ≤26 points on the MMSE was used to indicate categorically defined poor cognitive performance (cognitive impairment. The LS was defined by a score ≥16 points, and non-LS as <16 points, on the 25-question Geriatric Locomotive Function Scale (GLFS-25. Twenty-one participants (14.8% had an MMSE score ≤26, and 19.0% were found to have LS. Compared with the MMSE >26 group, the ≤26 group was significantly older, had a higher percentage of body fat, and a higher GLFS-25 score. Those with LS were significantly older, had a higher body mass index, a higher percentage of body fat, and a lower MMSE score. Participants in the LS group had higher odds of cognitive impairment than those without LS [odds ratio (OR =3.08] by logistic regression analysis adjusted for age. Furthermore, participants with GLFS-25 scores ≥6 had higher odds of cognitive impairment than those with a GLFS-25 score <6 by logistic regression analysis adjusted for both age (OR =4.44, and age and percent body fat (OR =4.12.

    A project to import a large amount of liquid hydrogen (LH2) from Australia by a cargo carrier, which is equipped with two 1250 m3 tanks, is underway in Japan. It is important to understand sloshing and boil-off characteristics inside the LH2 tank during marine transportation. However, the LH2 sloshing and boil-off characteristics on the sea have not yet been clarified. First experiment on the LH2 transportation of 20 liter with magnesium diboride (MgB2) level sensors by the training ship “Fukae-maru”, which has 50 m long and 449 ton gross weight, was carried out successfully inside Osaka bay on February 2, 2017. In the experiment, synchronous measurements of liquid level, temperature, pressure, ship motions, and accelerations as well as the rapid depressurization test were done. The increase rate of the temperature and the pressure inside the LH2 tank were discussed under the rolling and the pitching conditions.

    Previous studies in Western populations have linked caffeine intake with health status. While detailed dietary assessment studies in these populations have shown that the main contributors to caffeine intake are coffee and tea, the wide consumption of Japanese and Chinese teas in Japan suggests that sources of intake in Japan may differ from those in Western populations. Among these teas, moreover, caffeine content varies widely among the different forms consumed (brewed, canned or bottled), suggesting the need for detailed dietary assessment in estimating intake in Japanese populations. Here, because a caffeine composition database or data obtained from detailed dietary assessment have not been available, we developed a database for caffeine content in Japanese foods and beverages, and then used it to estimate intake in a Japanese population. The caffeine food composition database was developed using analytic values from the literature, 16 d weighed diet records were collected, and caffeine intake was estimated from the 16 d weighed diet records. Four areas in Japan, Osaka (Osaka City), Okinawa (Ginowan City), Nagano (Matsumoto City) and Tottori (Kurayoshi City), between November 2002 and September 2003. Two hundred and thirty Japanese adults aged 30-69 years. Mean caffeine intake was 256.2 mg/d for women and 268.3 mg/d for men. The major contributors to intake were Japanese and Chinese teas and coffee (47 % each). Caffeine intake above 400 mg/d, suggested in reviews to possibly have negative health effects, was seen in 11 % of women and 15 % of men. In this Japanese population, caffeine intake was comparable to the estimated values reported in Western populations.

Yokukansan has also become a popular drug combination in Japan, especially for the behavioral and psychiatric symptoms of dementia (BPSD. Recent studies have shown that yokukansan might also be quite effective against BPSD occurring in association with other types of dementia, such as Alzheimer's disease, Lewy body disease, Parkinson's disease with dementia, frontotemporal dementia, and vascular dementia. Researchers have intensively investigated yokukansan, focusing on the pharmacological mechanisms against glutamate-mediated excitotoxicity. This traditional Chinese and Japanese medicine holds potential promise for improving BPSD in elderly patients suffering from dementia.Keywords: yokukansan, dementia, Alzheimer's disease, behavioral and psychological symptoms of dementia, Kampo, glutamate

    The source and routes of diarrheagenic Escherichia coli (DEC) remain poorly understood. To investigate the involvement of domestic animals in the dissemination of DEC, the prevalence of DEC in foods and fecal specimens from cattle, pigs, chickens, healthy carriers, and patients in Osaka and Hyogo, Japan was investigated using a multiplex real-time Polymerase Chain Reaction assay. The most abundant virulence genes were astA and eae, which had a prevalence 46.8% and 27.4%, respectively. Additionally, stx1 (26.6%) and stx2 (45.9%) were prevalent in cattle feces, while est (8.5%) and elt (7.6%) were prevalent in pig feces. afaB was the second-most prevalent gene in patients and healthy carriers, and it had detection rates of 5.1% and 8.1%, respectively. In contrast, afaB was not detected in animal feces or foods, except for three porcine fecal samples. The aggR gene was more prevalent in humans than in foods or animal feces. Both Shiga toxin-producing E. coli and atypical enteropathogenic E. coli carried by cattle may be sources for diarrheal diseases in humans. Pigs may be a source for human enterotoxigenic E. coli infections, whereas humans are expected to be the reservoir for diffusely adhering E. coli, enteroaggregative E. coli, and enteroinvasive E. coli.

    This is a technological assessment of electric automotive vehicles, high speed magnetic levitation trains and hyperspeed superconductive magnetic levitation trains in Japan. It includes conventional battery electric vehicles for the automotive application, conventional magnetic levitation trains with peak speeds of 300 km/h and superconductive levitation trains capable of speeds over 500 km/h in transcontinental service. These electric vehicles have been under development since 1971 and are now considered ready for introduction into intercity commercial service. Conventional magnetic levitation trains are targeted to connect New Chitose International Airport with Sapporo and shorter connections in LasVegas, Philadelphia and Miami. The first superconductive train is planned for the Osaka to Tokyo link by the year 2000, a distance of 515 km. The initial step has been taken with approval of funding for the first five year phase of construction beginning with the Kansai project near Osaka

    Beginnings of the study of Western sciences, "Rangaku," in Kyoto and Osaka in the late 18th century are reviewed. Profiles and achievements of several active learners are briefly described; they include Koishi Genzui (Osaka-Kyoto), Tsuji Ranshitsu (Kyoto), Kimura Kenkadō (Osaka), and Hashimoto Sōkichi (Osaka). Genzui, after having successfully made good relations with Sugita Genpaku and Ohtsuki Gentaku, leading masters of the Edo school, played a role of an advocator for promoting "Rangaku" in Osaka and Kyoto. As a result, Kenkadō attained the publication of his book "Ikkaku Sankō," a monograph of the Western crude drug unicorn, with the help of Gentaku, who had translated a Dutch reference into Japanese for him. Ranshitsu and Sōkichi were taught the Dutch language by Gentaku; Sōkichi is known as the founder of "Rangaku" in Osaka.

    Smoking cessation is one of the most important items for improvement of health in Japan. The Japanese government started a new campaign called the "Health Japan 21" to promote better health of Japanese citizens in the 21st century. The purpose of the present study was to observe the situation of the municipalities throughout Japan regarding implementation of anti-smoking countermeasures and setting of the level of target values to be achieved over the next ten years. Mail questionnaire forms were sent to 953 municipalities which had formulated specific local plans for the promotion of health. Of this total, 793 (83.2%) responded to the inquiry. The most commonly implemented countermeasure against smoking was restricting smoking only to limited areas in municipality offices (75%), followed by providing support for stopping smoking (35%), and providing a complete smoke free environment in municipality offices (32.4%). Proportions of local governments putting a ban on smoking on public roads (7.5%), giving publicity to restaurants with smoking restrictions (vending machines and restricting tobacco advertisement. Most municipalities have made much of anti-smoking activities. However, measures for school children were not satisfactorily implemented. The execution rates for anti-smoking activities are low in small-scale municipalities and therefore it is necessary to provide particular support in these cases.

    This paper examines the effects of different levels of exposure to airport noise on the physical growth of children. Heights and weights of 6686 three-year-old boys and girls were measured between April 1972 and March 1974. These children are grouped into one of five exposure levels according to their exposure to noise from nearby Osaka International Airport in Japan. The frequency of growth inhibition is examined in each noise group and compared across groups. The frequency of very short boys and girls (less than 87 cm) increases significantly ( p short stature (10th percentile of local standards), the presence of moderate growth inhibition also is related to the level of airport noise, more so in males than females. With a third and less restrictive definition (less than 91 cm), the association is still present. Parallel analyses with weight did not find significant effects of noise exposure. We conclude that airport noise exposure may be related to a greater frequency of children of very small stature. We interpret this as evidence for a long-term physical effect of airport noise on children.

    The 2011 great Tohoku earthquake (Mw 9.0) occurred on March 11, 2011, and the largest aftershock (Mw 7.7) at the region adjacent to south boundary of the mainshock's source region. Long-period ground motions (1-10s) of large amplitude were observed in the Osaka sedimentary basin about 550-800km away from the source regions during both events. We studied propagation and site characteristics of these ground motions, and found some common features between these two events in the Osaka basin. (1) The amplitude of horizontal components of the ground motion at the site-specific period is amplified at each sedimentary station. The predominant period is around 7s in the bayside area where the largest pSv were observed. (2) The velocity Fourier spectra have their peak values around 7s at the bedrock sites surrounding the Osaka basin. (3) Two remarkable wave packets separated by 30s propagating from stations around the Nobi plain to the bedrock sites near the Osaka basin were seen in the pasted-up velocity waveforms from the source regions to the Osaka basin for both events (Sato et al., 2012). Therefore, large long-period ground motions in the Osaka basin are generated by the combination of propagation-path and basin effects. Firstly, we simulate ground motions due to the largest aftershock using three-dimensional FDM (GMS; Aoi and Fujiwara, 1999). The reason we focus on the largest aftershock is that this event has a relatively small rupture area and simple rupture process compared to the mainshock. The source model is based on the model estimated by Kubo et al. (2013). The velocity structure model is a three-dimensional velocity structure based on the Japan Integrated Velocity Structure Model (Koketsu et al., 2012) and the layer of Vs 350m/s in this model is replaced with one of Vs 500m/s. The minimum effective period in this computation is 3s. Then, we compare synthetic waveforms with observed ones. At CHBH14, the nearest station to the source and 60km away from the

    2013-04-01

    As one contribution to 'Global Heritage Stone Resources' (GHSR), some stone heritages in Japan, which are nominated in the interim list, are briefly introduced. The geology of Japanese Islands where are the one of the most active areas in the history of the Earth, is very complicated. Therefore Japanese Islands consist of various kinds of minerals and rocks. Some of them were used to make stone implements and accessories. Japanese people also used to the best possible advantage to built tombstone, gate, pavement ,and the basement and wall of the large building such as temples, shrines, castles and modern buildings. 1. Stone Heritages of Pre-historical age: In the late Pleistocene and the early Holocene, ancient Japanese used obsidian cooled rapidly from rhyolitic magma.to make small implements and accessories. For example, Shirataki, Hokkaido (north island) is the largest place producing obsidian in Japan where Paleolithic people made arrowhead, knives and so on. Another example, Jade yielded in Itoigawa City, Japan Sea coast of central Japan, was made in the metamorphic rock about five hundred million years ago. Itoigawa area is only one place where jade is abundantly produced in Japan. Ancient people had been already collected and processed to ornaments although it is very hard and traded in wide area more than several thousand years ago. 2. Stone Heritages of Historical age: 2.1 Archaeological remains: In the Kofun (old mound) period (250 to 538 AD), stone burial chambers were used for old mounds to preserve against the putrefaction and to protect from the theft. For example, Ishibutai Kofun ("ishi" means "stone" and "butai" means "stage") in Nara old capital city, southwest Japan, is the largest known megalithic structure made of granite in Japan. 2.2 Stone walls of some typical castles Stones used is because of not only the rich reserves of rocks but also restriction of transportation. Osaka (second biggest city) castle, are composed of Cretaceous granite

    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.

    Reflection survey is conducted using three traverse lines in Sakai City for confirming the presence of a southward stretch of the Uemachi fault underground along the western periphery of the Uemachi terrace, Osaka, and for elucidating its connection to the Sakamoto fault distributed near Izumi. Another reflection survey is conducted in the bed of Kanzaki river, Osaka, for the confirmation of its connection to the Nembutsuji-zan fault in Senri hillock. It is estimated on the basis of boring data that there exists another flexural structure approximately 3km south of the flexural structure whose presence is confirmed by the Sakai second traverse line. Accordingly, possibilities are high that the southward stretch of the Uemachi fault connects to the Sakamoto fault. The confirmation by the Kanzaki river traverse line of the flexural structure again confirms the continuity between the Uemachi fault and Nembutsuji-zan fault. The above-said findings enable an inference that the three faults of Nembutsuji-zan, Uemachi, and Sakamoto constitute a chain of active faults. Furthermore, there exists an active fault to the south of the Sakamoto fault, which zigzags to the south on the right-hand side as far as the south of the Kumeda pond. Accordingly, the Uemachi fault system as a whole spans approximately 43km from the northern end of the Nembutsuji-zan fault as far as the south of the Kumeda pond. 5 refs., 6 figs.

    2013-12-01

    The three-dimensional velocity structure model for the Osaka sedimentary basin, southwest Japan is developed and improved based on many kinds of geophysical explorations for decades (e.g., Kagawa et al., 1993; Horikawa et al., 2003; Iwata et al., 2008). Recently, our project (Sekiguchi et al., 2013) developed a new three-dimensional velocity model for strong motion prediction of the Uemachi fault earthquake in the Osaka basin considering both geophysical and geological information by adding newly obtained exploration data such as reflection surveys, microtremor surveys, and receiver function analysis (hereafter we call UMC2013 model) . On April 13, 2013, an inland earthquake of Mw5.8 occurred in Awaji Island, which is close to the southwestern boundary of the aftershock area of the 1995 Kobe earthquake. The strong ground motions are densely observed at more than 100 stations in the basin. The ground motion lasted longer than four minutes in the Osaka urban area where its bedrock depth is about 1-2 km. This long-duration ground motions are mainly due to the surface waves excited in this sedimentary basin whereas the magnitude of this earthquake is moderate and the rupture duration is expected to be less than 5 s. In this study, we modeled long-period (more than 2s) ground motions during this earthquake to check the performance of the present UMC2013 model and to obtain a better constraint on the attenuation factor of sedimentary part of the basin. The seismic wave propagation in the region including the source and the Osaka basin is modeled by the finite difference method using the staggered grid solving the elasto-dynamic equations. The domain of 90km×85km×25.5km is modeled and discretized with a grid spacing of 50 m. Since the minimum S-wave velocity of the UMC2013 model is about 250 m/s, this calculation is valid up to the period of about 1 s. The effect of attenuation is included in the form of Q(f)=Q0(T0/T) proposed by Graves (1996). A PML is implemented in

    Recently, the number of ambulance dispatches has been increasing in Japan, and it is therefore difficult for hospitals to accept emergency patients smoothly and appropriately because of the limited hospital capacity. To facilitate the process of requesting patient transport and hospital acceptance, an emergency information system using information technology (IT) has been built and introduced in various communities. However, its effectiveness has not been thoroughly revealed. We introduced a smartphone app system in 2013 that enables emergency medical service (EMS) personnel to share information among themselves regarding on-scene ambulances and the hospital situation. The aim of this study was to assess the effects of introducing this smartphone app on the EMS system in Osaka City, Japan. This retrospective study analyzed the population-based ambulance records of Osaka Municipal Fire Department. The study period was 6 years, from January 1, 2010 to December 31, 2015. We enrolled emergency patients for whom on-scene EMS personnel conducted hospital selection. The main endpoint was the difficulty experienced in gaining hospital acceptance at the scene. The definition of difficulty was making ≥5 phone calls by EMS personnel at the scene to hospitals until a decision to transport was determined. The smartphone app was introduced in January 2013, and we compared the patients treated from 2010 to 2012 (control group) with those treated from 2013 to 2015 (smartphone app group) using an interrupted time-series analysis to assess the effects of introducing this smartphone app. A total of 600,526 emergency patients for whom EMS personnel selected hospitals were eligible for our analysis. There were 300,131 emergency patients in the control group (50.00%, 300,313/600,526) from 2010 to 2012 and 300,395 emergency patients in the smartphone app group (50.00%, 300,395/600,526) from 2013 to 2015. The rate of difficulty in hospital acceptance was 14.19% (42,585/300,131) in the

    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.

    Full Text Available The current design weather data used for heating, ventilation, and air conditioning (HVAC design in Japan was created using an old data period. New design weather data should be created to reflect recent local climate change. Based on our previous proposal of creating design weather data with two weather indices (dry-bulb temperature and enthalpy for HVAC design, design weather data for Osaka was created using more recently-measured weather data (period: 2001~2015 from the Japan Meteorological Agency (JMA in this study. The effect of recent climate change on the design weather data created with eight proposed methods was found. It showed the change in weather elements for cooling design clearly trends to warmer and drier weather, with more solar radiation and lower enthalpy, while the trends in heating design are less clear, mainly showing higher enthalpy. Furthermore, the difference in the peak load for the heating and cooling designs using the new and old design weather data was compared. The comparison showed that the minimum difference in peak load for the heating design was found using the mean daily dry-bulb temperature as the first and second indices; for the cooling design, the minimum difference in peak load was found using mean daily enthalpy as both the first and second indices.

We investigated the ­sex-specific impact of early-life adversity on chronic pain, chronic multisite pain, and somatizing tendency with chronic pain. Methods: We examined 4229 respondents aged 20–79 years who participated in the Pain Associated Cross-Sectional Epidemiological Survey in Japan. Outcomes were: 1 chronic pain prevalence, 2 multisite pain (≥3 sites prevalence, and 3 multiple somatic symptoms (≥3 symptoms among respondents with chronic pain related to the presence or absence of early-life adversity. Multivariable-adjusted odds ratios (ORs were calculated with 95% confidence intervals using a logistic regression model including age, smoking status, exercise routine, sleep time, body mass index, household expenditure, and the full distribution of scores on the Mental Health Inventory-5. We further adjusted for pain intensity when we analyzed the data for respondents with chronic pain. Results: The prevalence of chronic pain was higher among respondents reporting the presence of early-life adversity compared with those reporting its absence, with multivariable ORs of 1.62 (1.22–2.15, p<0.01 in men and 1.47 (1.13–1.90, p<0.01 in women.

    The Japanese inertial fusion program has made important progress towards implosion fusion process and the technical development required for realizing the breakeven of inertial fusion energy. The key issues for the ICF research are the development of a high power driver, the pertinent pellet design for implosion by a super computer code, and the diagnostics of implosion process with high space and time resolution. The Institute of Laser Engineering (ILE), Osaka University, is the central laboratory for ICF research in Japan. The ILE Osaka has advanced the Kongo Project aiming at the breakeven of inertial fusion since 1980, and as the first phase, the Gekko 12 Nd glass laser of 20 kJ having 12 beams was constructed. The ILE has also the Lekko 8 CO 2 laser and the Reiden 4 light ion beam machine. In the second phase, a 100 kJ class driver will be provided. At the ILE, rare gas halide lasers such as KrF and ArF have been investigated. Laser plasma coupling, the scaling law for implosion pressure, the invention of a new type target ''Cannonball'', and the development of computer codes are described. Also the activities in universities, government laboratories and industrial companies are reported. (Kako, I.)

    Three-dimensional (3D) geological model of subsurface structure plays an important role in developing infrastructures. In particular, the 3D geological model in urban area is quite helpful to solve social problems such as underground utilization, environmental preservation, and disaster assessment. Over the past few years, many studies have been made on algorithms for 3D geological modeling. However, most of them have given little attention to objectivity of the model and traceability of modeling procedures. The purpose of this study is to develop an algorithm for constructing a 3D geological model objectively and for maintaining high-traceability of modeling procedures. For the purpose of our work, we proposed a new algorithm for 3D geological modeling using gridded geological boundary surfaces and the "logical model of geologic structure". The geological boundary surface is given by a form of Digital Elevation Model (DEM). The DEM is generated based on geological information such as elevation, strike and dip by using a unique spline-fitting method. The logical model of geological structure is a mathematical model that defines a positional relation between geological boundary surfaces and geological units. The model is objectively given by recurrence formula derived from a sequence of geological events arranged in chronological order. We applied the proposed algorithm into constructing a 3D subsurface geological model of the western Osaka Plane, southwest Japan. The data used for 3D geological modeling is a set of borehole data provided by Osaka City and Kansai Geoinformatics Agency. As a result, we constructed a 3D model consistent with the subjective model reported in other studies. In addition, all information necessary for modeling, such as the used geological information, the parameters of surface fitting, and the logical model, was stored in text files. In conclusion, we can not only construct 3D geological model objectively but also maintain high

  11. A University–Industry Collaborative Entrepreneurship Education Program as a Trading Zone: The Case of Osaka University

    2017-06-01

    Full Text Available Two complementary problems are that busy practitioners find it difficult to access academic knowledge and university students lack practical experience. University–industry collaborative education is a potential solution for both of these problems by bringing together theoretical insights from universities and experiential know-how from industry. However, university–industry collaborative education has not been sufficiently studied to offer clear frameworks and mechanisms to foster effective knowledge exchanges between these two groups. In this article, we propose the metaphor of a “trading zone” as a potential analytical framework for implementing this method of education. Applying this framework to the analysis of a university–industry collaborative education program, this study proposes that the exchange of knowledge between students and practitioners is the essential learning experience and that it is made more meaningful by the heterogeneity between students and practitioners. The shared language provided by the program and those who deliver it make the exchanges efficient, and the temporary and extraordinary nature of the program accelerate those exchanges. Here, we analyze the case of Osaka University in Japan to illustrate the framework and develop associated propositions to encourage further study and validation of the framework.

    Full Text Available Currently, urban heat island (UHI phenomenon and building energy consumptions are becoming serious. Strategies to mitigate UHI and reduce building energy consumptions are implemented worldwide. In Japan, as an effective means of mitigating UHI and saving energy of buildings, highly reflective (HR and green roofs are increasingly used. In order to evaluate the effect of roofs with high reflection and thermal insulation on the energy conservation of buildings, we investigated the roof solar reflectivity of the subject school in Osaka, in which the HR roofing sheet was installed on the roof from 2010. Thermal loads, including cooling and heating loads of the top floor of school, were calculated using the thermal load calculation software, New HASP/ACLD-β. Comparing the thermal loads after HR roofing sheet installation to previous, the annual thermal load decreased about 25 MJ/m2-year and the cooling load decreased about 112 MJ/m2-year. However, the heating load increased about 87 MJ/m2-year in winter. To minimize the annual thermal load, thermal insulation of the roof was also considered be used together with HR roofing sheet in this study. The results showed that the combination of HR roofing sheet and high thermal insulation is more effective to reduce the annual thermal load.

Green innovations and environmentally friendly production systems based on physics, chemistry, materials science, and electronic engineering will be indispensable for ensuring renewable energy and establishing a sustainable society. In particular, production design, materials processing, and fabrication technologies such as welding and joining will be very important components of such green innovations. For these reasons, the International Symposium on Materials Science and Innovation for Sustainable Society - eco-materials and eco-innovation for global sustainability - (ECO-MATES 2011) was organized by the Joining and Welding Research Institute (JWRI) and the Center of Environmental Innovation Design for Sustainability (CEIDS), Osaka University. ECO-MATES 2011 was held at Hotel Hankyu Expo Park, Osaka, Japan from 28-30 November 2011. 435 participants from 20 countries around the world attended the symposium. 149 oral presentations including 60 invited talks and 160 posters were presented at the symposium to discuss the latest research and developments in green innovations in relation to environmental issues. The topics of the symposium covered all environmentally related fields including renewable energy, energy-materials, environment and resources, waste and biomass, power electronics, semiconductor, rare-earth metals, functional materials, organic electronics materials, electronics packaging, smart processing, joining and welding, eco-efficient processes, and green applied physics and chemistry. Therefore, 55 full papers concerning green innovations and environmentally benign production were selected and approved by the editorial board and the program committee of ECO-MATES 2011. All papers were accepted through peer review processes. I believe that all the papers have many informative contents. On behalf of the steering committee of the symposium, I would like to express

  16. Fast ignition studies at Osaka University

    2007-01-01

    After the invention of the chirped pulse amplification technique [1], the extreme conditions of matters have become available in laboratory spaces and can be studied with the use of ultra intense laser pulse (UILP) with a high energy. One such example is the fast ignition [2] where UILP is used to heat a highly compressed fusion fuel core within 1-10 pico-seconds before the core disassembles. It is predicted possible with use of 50-100 kJ lasers for both imploding the fuel and heating [2] to attain a large fusion gain. Fast ignition was shown to be a promising new scheme for laser fusion [3] with a PW (= 10 1 5 W) UILP and GEKKO XII laser systems at Osaka. Many new physics have been found with use of UILP in a relativistic parameter regime during the process of the fast ignition studies. UILP can penetrate into over-dense plasma for a couple hundred microns distance with a self-focusing and relativistic transparency effects. Hot electrons of 1-100 MeV can be easily created and are under studies for its spectral and emission angle controls. Strong magnetic fields of 10's of MGauss are created to guide these hot electrons along the target surface [4]. Based on these results, a new and largest UILP laser machine of 10 kJ energy at PW UILP peak power is under construction to test if we can achieve the sub-ignition fusion condition at Osaka University. The machine requires challenging optical technologies such as large size (0.9 m) gratings, tiling these gratings for UILP compression; segmenting four large UILP beams to obtain diffraction limited focal spot. We would like to over-view all of these activities. References [1]D. STRICKLAND and G. MOUROU, Opt. Commun., 56, 219 (1985) [2] S. ATZENI et al., Phys Plasmas, 6, 3316 (1999) [3] R. KODAMA, K.A.

Because cytokines such as tumor necrosis factor (TNF-α and interleukin (IL-6 play a major role in the development of RA, their targeting could constitute a reasonable novel therapeutic strategy for treating RA. Indeed, worldwide clinical trials of TNF inhibiting biologic disease modifying antirheumatic drugs (bDMARDs including infliximab, adalimumab, golimumab, certolizumab pegol, and etanercept as well as the humanized anti-human IL-6 receptor antibody, tocilizumab, have demonstrated outstanding clinical efficacy and tolerable safety profiles, resulting in worldwide approval for using these bDMARDs to treat moderate to severe active RA in patients with an inadequate response to synthetic disease modifying antirheumatic drugs (sDMARDs. Although bDMARDs have elicited to a paradigm shift in the treatment of RA due to the prominent efficacy that had not been previously achieved by sDMARDs, a substantial percentage of patients failed primary or secondary responses to bDMARD therapy. Because RA is a heterogeneous disease in which TNF-α and IL-6 play overlapping but distinct pathological roles, further studies are required to determine the best use of TNF inhibitors and tocilizumab in individual RA patients.

    Under the current policy on the research and development of nuclear fusion in Japan, as enunciated by the Atomic Energy Commission of Japan, the type of a prototype fusion reactor will be chosen after 2020 from tokamak, helical or some other type including the inertial confinement fusion using lasers. A prototype fusion reactor is the next step following the tokamak type International Thermonuclear Experimental Reactor (ITER). With the prototype reactor, the feasibility as a power plant will be examined. At present the main research and development of nuclear fusion in Japan are on tokamak type, which have been promoted by Japan Atomic Energy Research Institute (JAERI). As for the other types of nuclear fusion, researches have been carried out on the helical type in Kyoto University and National Institute for Fusion Science (NIFS), the mirror type in Tsukuba University, the tokamak type using superconductive coils in Kyushu University, and the laser fusion in Osaka University. The features and the present state of research and development of the Large Helical Device and the laser fusion which is one step away from the break-even condition are reported. (K.I.)

    In Japan, the main source of dioxins is incinerators. This study examined the relationship between the distance of schools from municipal waste incineration plants and the prevalence of allergic disorders and general symptoms in Japanese children. Study subjects were 450,807 elementary school children aged 6-12 years who attended 996 public elementary schools in Osaka Prefecture in Japan. Parents of school children completed a questionnaire that included items about illnesses and symptoms in the study child. Distance of each of the public elementary schools from all of the 37 municipal waste incineration plants in Osaka Prefecture was measured using geographical information systems packages. Adjustment was made for grade, socioeconomic status and access to health care per municipality. Decreases in the distance of schools from the nearest municipal waste incineration plant were independently associated with an increased prevalence of wheeze, headache, stomach ache, and fatigue (adjusted odds ratios [95% confidence intervals] for shortest vs. longest distance categories =1.08 [1.01-1.15], 1.05 [1.00-1.11], 1.06 [1.01-1.11], and 1.12 [1.08-1.17], respectively). A positive association with fatigue was pronounced in schools within 4 km of the second nearest municipal waste incineration plant. There was no evident relationship between the distance of schools from such a plant and the prevalence of atopic dermatitis or allergic rhinitis. The findings suggest that proximity of schools to municipal waste incineration plants may be associated with an increased prevalence of wheeze, headache, stomach ache, and fatigue in Japanese children

  4. Mutation analysis of 2009 pandemic influenza A(H1N1 viruses collected in Japan during the peak phase of the pandemic.

    Jean-Étienne Morlighem

    Full Text Available BACKGROUND: Pandemic influenza A(H1N1 virus infection quickly circulated worldwide in 2009. In Japan, the first case was reported in May 2009, one month after its outbreak in Mexico. Thereafter, A(H1N1 infection spread widely throughout the country. It is of great importance to profile and understand the situation regarding viral mutations and their circulation in Japan to accumulate a knowledge base and to prepare clinical response platforms before a second pandemic (pdm wave emerges. METHODOLOGY: A total of 253 swab samples were collected from patients with influenza-like illness in the Osaka, Tokyo, and Chiba areas both in May 2009 and between October 2009 and January 2010. We analyzed partial sequences of the hemagglutinin (HA and neuraminidase (NA genes of the 2009 pdm influenza virus in the collected clinical samples. By phylogenetic analysis, we identified major variants of the 2009 pdm influenza virus and critical mutations associated with severe cases, including drug-resistance mutations. RESULTS AND CONCLUSIONS: Our sequence analysis has revealed that both HA-S220T and NA-N248D are major non-synonymous mutations that clearly discriminate the 2009 pdm influenza viruses identified in the very early phase (May 2009 from those found in the peak phase (October 2009 to January 2010 in Japan. By phylogenetic analysis, we found 14 micro-clades within the viruses collected during the peak phase. Among them, 12 were new micro-clades, while two were previously reported. Oseltamivir resistance-related mutations, i.e., NA-H275Y and NA-N295S, were also detected in sporadic cases in Osaka and Tokyo.

    In Japan potatoes have been irradiated for the purpose of sprout inhibition for more than 20 years and more than ten thousand irradiated potatoes are circulated in Japanese market in recent years. Nevertheless, there are few surveys about the consumer status toward food irradiation in Japan. We have been held 'Radiation Fair -- The relationship between daily life and radiation--' during summer vacation season in August for more than 10 years in Osaka, the largest city of western Japan, for the purpose of public education and information transfer of radiation and radiation-related technology especially to school kids. We displayed 200 kg of irradiated potatoes together with explanatory panels. We distributed questionnaires to the senior high school students (16 years old) and upward visitor for recent 3 years to inquire their status toward radiation and irradiated products including irradiated potatoes as well as impression toward the displays. According to the survey results in 1997, the ratio of respondents who had heard of irradiated potatoes was 51% of 228 answers. This value was smaller than those of the Gallop survey conducted in the United States (73%). After viewing the display and description of irradiated potatoes, almost half of the respondents indicated a positive feeling for tasting the irradiated potatoes. Most of the respondents chose one of the following issues, Freshness' (37%), 'Open date' (13%), or 'Food additives' (34%) as the major concerns about food safety. Interestingly, 'Pesticide' and/or 'Foodborne pathogen' highly were chosen by only 15% of the respondents in total even though these issue were highly ranked in the US surveys. These results indicate that original methodology is necessary for distributing the information related food irradiation related food irradiation efficiently. (J.P.N)

    Dry eye disease has become an important health problem. A lack of concordance between self-reported symptoms and the outcome of dry eye examinations has raised questions about dry eye disease. To explore the association between subjective happiness and objective and subjective symptoms of dry eye disease. The study adopted a cross-sectional design. All the employees of a company in Osaka, Japan. 672 Japanese office workers using Visual Display Terminals (age range: 26-64 years). The dry eye measurement tools included the Schirmer test, conjunctivocorneal staining, the tear film break-up time, as well as the administration of a dry eye symptoms questionnaire. Happiness was measured by the Subjective Happiness Scale. Dry eye examination parameters, dry eye symptoms questionnaires, and the Subjective Happiness Scale score. Of the 672 workers, 561 (83.5%) completed the questionnaires and examinations. The mean Subjective Happiness Scale score was 4.91 (SD = 1.01). This score was inversely correlated with the dry eye symptom score (r = -0.188, p happiness was the lowest in the group without objective results, but reported subjective symptoms of dry eyes (p happiness and self-reported symptoms of dry eyes. Findings of this study revealed a new perspective on dry eye disease, including the potential for innovative treatments of a specific population with dry eye disease.

    BMT in Japan was started in 1975. From 1981 Japan BMT study group was organized by the grant of ministry of health and welfare Japan. A rapid increase of number of BMT parallel to the improvement of results was observed in the 489 patients by the registry of this group. The major causes of failure of BMT were interstitial pneumonitis (IP), relapse of leukemia, infection, and graft versus host disease (GVHD). The incidence of IP decreased very rapidly by fractionation of total body irradiation and anti-cytomegalovirus (CMV) antibody negative platelet transfusion. Prophylactic administration of anti-CMV immunoglobulin produced also significant reduction of IP. In the double blind controled study oral administration of aciclovir revealed significant reduction of herpes stomatitis, followed by the reduction of other infections including sepsis. For the decontamination of bioclean room we have developed ozone decontamination, which revealed to be very effective for fungus. Colony stimulating factor was found to shorten the period of granulocytopenia. The patients with GVHD showed lower incidence of relapse of leukemia than those without GVHD. In the patients who received BMT during their first remission of ALL. Long survival rate was 63 %, for ANLL in the first remission, 64 % and for CML in the chronic phase, 40 %. Out of the first 20 BMT patients of the center for adult diseases Osaka, only three are living now, while out of the next 25 patients 22 are living disease free. Major items of modification of BMT procedures between those two groups were cyclosporine A, colony stimulating factor, fractionated TBI, CMV-negative platelet donar, BMT in first remission for acute leukemia or chronic phase in CML. BMT seemed to be a very reliable and promising treatment of leukemia with a very high possibility of complete cure. (author)

    Osaka Gas Co. has been developing a planar type SOFC (OG type SOFC) which has a suitable structure for stacking. Murata Mfg. Co. has begun to develop the OG type SOFC stack through joint program since 1993. Figure 1 shows OG type cell structure. Because each cell is sustained by cell holders acting air manifold, the load of upper cell is not put on the lower cells. Single cell is composed of 3-layered membrane and LaCrO{sub 3} separator. 5 single cells are mounted on the cell holder, connected with Ni felt electrically, and bonded by glassy material sealant. We call the 5-cell stack a unit. Stacking 13 units, we succeeded 870 W generation in 1993. But the power density was low, 0.11 Wcm{sup -2} because of crack in the electrolyte and gas leakage at some cells.

    Full Text Available The radionuclides released from the Fukushima Daiichi nuclear power plant in 2011 pose a health risk. In this study, we estimated the 1st-year average doses resulting from the intake of iodine 131 (131I and cesium 134 and 137 (134Cs and 137Cs in drinking water and food ingested by citizens of Fukushima City (∼50 km from the nuclear power plant; outside the evacuation zone, Tokyo (∼230 km, and Osaka (∼580 km after the accident. For citizens in Fukushima City, we considered two scenarios: Case 1, citizens consumed vegetables bought from markets; Case 2, citizens consumed vegetables grown locally (conservative scenario. The estimated effective doses of 134Cs and 137Cs agreed well with those estimated through market basket and food-duplicate surveys. The average thyroid equivalent doses due to ingestion of 131I for adults were 840 µSv (Case 1 and 2700 µSv (Case 2 in Fukushima City, 370 µSv in Tokyo, and 16 µSv in Osaka. The average effective doses due to 134Cs and 137Cs were 19, 120, 6.1, and 1.9 µSv, respectively. The doses estimated in this study were much lower than values reported by the World Health Organization and the United Nations Scientific Committee on the Effects of Atomic Radiation, whose assessments lacked validation and full consideration of regional trade in foods, highlighting the importance of including regional trade. The 95th percentile effective doses were 2-3 times the average values. Lifetime attributable risks (LARs of thyroid cancers due to ingestion were 1.7-37×10-6 (Case 1 and5.6-79×10-6 (Case 2 in Fukushima City, 0.73-13×10-6 in Tokyo, and 0.04-0.49×10- 6 in Osaka. The contributions of LARs of thyroid cancers due to ingestion were 5.4%-11% of all exposure (Case 1 and 11%-25% (Case 2 in Fukushima City [corrected].

    In in the early morning of Dec. 21, 1946, a great destructive earthquake occurred in southern-western Japan. According to the seismogram obtained in our university, the earthquake motion began at Tokyo from 4 h 20 m 10.4 s on Dec. 21, 1946. The maximum amplitude of NS, EW, and up-down components of the earthquake motion at Tokyo was 12.0 mm, 14.0 mm and 3.0 mm respectively, while the initial motion was composed of 80 μ south, 67 μ west and 20 μ down movements.

    Tuberculosis (TB) is a major public health problem. The Airin district of Osaka City has a large population of homeless persons and caregivers and is estimated to be the largest TB-endemic area in the intermediate-prevalence country, Japan. However, there have been few studies of homeless persons and caregivers. The objective of this study is to detect active TB and to assess the prevalence and risk factors for latent TB infection among homeless persons and caregivers. We conducted a cross-sectional study for screening TB infection (active and latent TB infections) using questionnaire, chest X-ray (CXR), newly available assay for latent TB infection (QuantiFERON-TB Gold In-Tube; QFT) and clinical evaluation by physicians at the Osaka Socio-Medical Center Hospital between July 2007 and March 2008. Homeless persons and caregivers, aged 30-74 years old, who had not received CXR examination within one year, were recruited. As for risk factors of latent TB infection, the odds ratios (OR) and 95% confidence intervals (95% CI) for QFT-positivity were calculated using logistic regression model. Complete responses were available from 436 individuals (263 homeless persons and 173 caregivers). Four active TB cases (1.5%) among homeless persons were found, while there were no cases among caregivers. Out of these four, three had positive QFT results. One hundred and thirty-three (50.6%) homeless persons and 42 (24.3%) caregivers had positive QFT results. In multivariate analysis, QFT-positivity was independently associated with a long time spent in the Airin district: ≥10 years versus homeless (OR = 2.53; 95% CI, 1.39-4.61) and for caregivers (OR = 2.32; 95% CI, 1.05-5.13), and the past exposure to TB patients for caregivers (OR = 3.21; 95% CI, 1.30-7.91) but not for homeless persons (OR = 1.51; 95% CI, 0.71-3.21). Although no active TB was found for caregivers, one-quarter of them had latent TB infection. In addition to homeless persons, caregivers need examinations for

    2009-07-01

    This volume of Journal of Physics: Conference Series contains invited and contributed peer-reviewed papers that were presented at the 16th International Symposium on Boron, Borides and Related Materials (ISBB 2008), which was held on 7-12 September 2008, at Kunibiki Messe, Matsue, Japan. This triennial symposium has a half-century long history starting from the 1st meeting in 1959 at Asbury Park, New Jersey. We were very pleased to organize ISBB 2008, which gathered chemists, physicists, materials scientists as well as diamond and high-pressure researchers. This meeting had a strong background in the boron-related Japanese research history, which includes the discovery of superconductivity in MgB2 and development of Nd-Fe-B hard magnets and of YB66 soft X-ray monochromator. The scope of ISBB 2008 spans both basic and applied interdisciplinary research that is centered on boron, borides and related materials, and the collection of articles defines the state of the art in research on these materials. The topics are centered on: 1. Preparation of new materials (single crystals, thin films, nanostructures, ceramics, etc) under normal or extreme conditions. 2. Crystal structure and chemical bonding (new crystal structures, nonstoichiometry, defects, clusters, quantum-chemical calculations). 3. Physical and chemical properties (band structure, phonon spectra, superconductivity; optical, electrical, magnetic, emissive, mechanical properties; phase diagrams, thermodynamics, catalytic activity, etc) in a wide range of temperatures and pressures. 4. Applications and prospects (thermoelectric converters, composites, ceramics, coatings, etc) There were a few discoveries of new materials, such as nanomaterials, and developments in applications. Many contributions were related to 4f heavy Fermion systems of rare-earth borides. Exotic mechanisms of magnetism and Kondo effects have been discussed, which may indicate another direction of development of boride. Two special sessions

    1998-01-01

    The Kobe earthquake struck at the edge of the densely populated Osaka-Kyoto corridor in southwest Japan. We investigate how the earthquake transferred stress to nearby faults, altering their proximity to failure and thus changing earthquake probabilities. We find that relative to the pre-Kobe seismicity, Kobe aftershocks were concentrated in regions of calculated Coulomb stress increase and less common in regions of stress decrease. We quantify this relationship by forming the spatial correlation between the seismicity rate change and the Coulomb stress change. The correlation is significant for stress changes greater than 0.2-1.0 bars (0.02-0.1 MPa), and the nonlinear dependence of seismicity rate change on stress change is compatible with a state- and rate-dependent formulation for earthquake occurrence. We extend this analysis to future mainshocks by resolving the stress changes on major faults within 100 km of Kobe and calculating the change in probability caused by these stress changes. Transient effects of the stress changes are incorporated by the state-dependent constitutive relation, which amplifies the permanent stress changes during the aftershock period. Earthquake probability framed in this manner is highly time-dependent, much more so than is assumed in current practice. Because the probabilities depend on several poorly known parameters of the major faults, we estimate uncertainties of the probabilities by Monte Carlo simulation. This enables us to include uncertainties on the elapsed time since the last earthquake, the repeat time and its variability, and the period of aftershock decay. We estimate that a calculated 3-bar (0.3-MPa) stress increase on the eastern section of the Arima-Takatsuki Tectonic Line (ATTL) near Kyoto causes fivefold increase in the 30-year probability of a subsequent large earthquake near Kyoto; a 2-bar (0.2-MPa) stress decrease on the western section of the ATTL results in a reduction in probability by a factor of 140 to

    Major nuclear research institutes in Japan are the Japan Atomic Energy Research Institute (JAERI), Nuclear Cycle Development Institute (JNC), National Research Institute of Radiological Science (NIRS), and the Institute of Physical and Chemical Research (RIKEN). In the 50s and 60s JAERI concentrated on the introduction of nuclear technology from overseas. Energy security issues led to the development of a strong nuclear power programme in the next two decades resulting in Japan having 50 light water cooled nuclear power plants in operation. Japan also worked on other reactor concepts. The current emphasis of JAERI is on advanced reactors and nuclear fusion. Its budget of 270 million US$ supports five research establishments. JAERI has strong collaboration with industry and university system on nuclear and other advanced research topics (neutron science, photon science). In many areas Japan has strong international links. JAERI has also been transferring know-how on radioisotope and radiation applications to the developing countries particularly through IAEA-RCA mechanisms. (author)

    Full Text Available Efforts are underway in Japan to promote “Smartway” next-generation roadways, which provide a variety of services through the use of advanced ITS technologies. In recent years, the National Institute for Land and Infrastructure Management (NILIM, part of the Ministry of Land, Infrastructure, Transport and Tourism (MLIT, has conducted public–private joint research on next-generation road services using ITS technologies. Field operational tests (FOTs of services including forward obstacle information provision and merging assistance using 5.8 GHz dedicated short range communication (DSRC were conducted on the Tokyo Metropolitan Expressway through FY2007. In FY2008–2009, FOTs were conducted in three major metropolitan areas—Tokyo, Nagoya, and Keihanshin (Kyoto, Osaka, and Kobe—to promote future deployment nationwide. These included tests of information provision services to alert drivers to forward obstacles hidden beyond the crest of an incline and prevent excessive speed on sharp curves. This paper presents an overview of these FOTs conducted by NILIM in recent years and their results.

Methods: We measured the post-void residual urinary volume in 19 patients with underactive bladders. All these patients had been under treatment with distigmine bromide and were prescribed acotiamide hydrochloride hydrate at a dose of 100 mg three times daily for 2 weeks. Results: Compared with the post-void residual urinary volume value at baseline (161.4±90.0 mL a statistically significant reduction was observed at the end of treatment (116.3±63.1 mL (P=0.006. The drug was generally well tolerated by the majority of patients. Conclusion: Maybe, acotiamide hydrochloride hydrate showed clinical efficacy in patients with underactive bladders and may, therefore, be used alternatively in patients who do not respond sufficiently to distigmine bromide.

    1986-01-01

    Strontium isotopic ratios of sixty-seven Tertiary volcanic rocks from the northeastern Honshu, Japan, were determined for the purpose of examining the genesis among the volcanic rocks. Two distince suites of volcanic rocks occur in the northeastern Honshu; the rocks older than 16 Ma (Monzen-Daijima Stege) of predominantly intermediate composition and the rocks younger than 16 Ma (Nishikurosawa-Funakawa Stege) with bimodal suite of mafic and felsic composition. Initial values of 87 Sr/ 86 Sr in the Teriary volcanic rocks from the northeastern Honshu, lie in the range from 0.7033 to 0.7068. High ( 87 Sr/ 86 Sr) I ratios are observed for the rocks older than 16 Ma from the Japan Sea side (H zone). It is noteworthy that the rocks younger than 16 Ma show significantly lower ( 87 Sr/ 86 Sr) I ratios in the Dewa Hill, Japan Sea coast and North Akita areas in the northeastern Honshu (L zone). The rocks younger than 16 Ma from the L zone can also be interpreted as having been originated as a mantle-diapir associated with the spreading of the Japan Sea basin. If the basaltic magma was formed from the diapir, the 87 Sr/ 86 Sr ratio would be close to the range from 0.7033 to 0.7037 as the low-Sr isotopic ratio zone (L zone) in the northeastern Honshu, Japan.

    Residents of long-term care facilities for the elderly are vulnerable to health care-associated infections. However, compared to medical institutions, long-term care facilities for the elderly lag behind in health care-associated infection control and prevention. We conducted a epidemiologic study to clarify the current status of infection control in long-term care facilities for the elderly in Japan. A questionnaire survey on the aspects of infection prevention and control was developed according to SHEA/APIC guidelines and was distributed to 617 long-term care facilities for the elderly in the province of Osaka during November 2016 and January 2017. The response rate was 16.9%. The incidence rates of health care-associated infection outbreaks and residents with health care-associated infections were 23.4 per 100 facility-years and 0.18 per 1,000 resident-days, respectively. Influenza and acute gastroenteritis were reported most frequently. Active surveillance to identify the carrier of multiple drug-resistant organisms was not common. The overall compliance with 21 items selected from the SHEA/APIC guidelines was approximately 79.2%. All facilities had infection control manuals and an assigned infection control professional. The economic burdens of infection control were approximately US$ 182.6 per resident-year during fiscal year 2015. Importantly, these data implied that physicians and nurses were actively contributed to higher SHEA/APIC guideline compliance rates and the advancement of infection control measures in long-term care facilities for the elderly. Key factors are discussed to further improve the infection control in long-term care facilities for the elderly, particularly from economic and social structural standpoints.

    We surveyed background level of radioactive contamination in city area of Osaka before combusting the wide area disposal of disastrous debris at a municipal waste incineration plant of Osaka city. The debris was caused by Tohoku district great earthquake disaster and suspected to be contaminated with radionuclides released from the Fukushima Daiichi Nuclear Power Plants. We also investigated radioactivity in incineration ash of municipal waste incineration plants and of sewage treatment plants, as well as in water clarifier sludge of potable water treatment plants, and evaluated the accumulation and cleansing of radioactive materials via the reverse logistic function of the city. Radioactive caesium deposited in Osaka city area was estimated to be approximately 4.3 GBq from the concentrations observed in the monthly fallout, whereas that collected as municipal wastes and sewage was estimated to be approximately 0.9 GBq a year in 2011. Even two years after the accident, "1"3"4Cs, which is the evidence of the Fukushima Daiichi Nuclear Power Plant accident, had been detected in the municipal wastes at a level comparable to the activities found just after the accident, however, the radioactive caesium concentration in fallout measured in the Osaka city area had decreased below a detection limit after May 2012. Introduction of materials contaminated with radioactive caesium from outside the city area was suspected because the observed contamination level was inexplicable by that of observed in the environmental wastes such as pruned branches which are contaminated by with the fallout in city area of Osaka.

    MicroRNAs have an important role in regulating arrhythmogenesis. MicroRNA-16 (miR-16) is predicted to target KCNJ2. The regulation of miR-16 is primarily due to NF-κB. Whether valsartan could downregulate miR-16 via the inhibition of NF-κB after MI and whether miR-16 targets KCNJ2 remain unclear. MI rats received valsartan or saline for 7days. The protein levels of NF-κB p65, inhibitor κBα (IκBα), and Kir2.1 were detected by Western blot analysis. The mRNA levels of Kir2.1 and miR-16 were examined by quantitative real-time PCR. Whole cell patch-clamp techniques were applied to record IK1. MiR-16 expression was higher in the infarct border, and was accompanied by a depressed IK1/KIR2.1 level. Additionally, miR-16 overexpression suppressed KCNJ2/KIR2.1 expression. In contrast, miR-16 inhibition or binding-site mutation enhanced KCNJ2/KIR2.1 expression, establishing KCNJ2 as a miR-16 target. In the MI rats, compared to saline treatment, valsartan reduced NF-κB p65 and miR-16 expression and increased IκBα and Kir2.1 expression. In vitro, angiotensin II increased miR-16 expression and valsartan inhibited it. Overexpressing miR-16 in cells treated with valsartan abrogated its beneficial effect on KCNJ2/Kir2.1. NF-κB activation directly upregulates miR-16 expression. miR-16 controls KCNJ2 expression, and valsartan ameliorates Kir2.1 after MI partly depending on the NF-κB-miR-16 pathway.

    The quality control survey in the title has been conducted every year from 1978 to improve the quality of the in vitro tests and this report gives the survey results done in 1999. The survey was performed in 133 facilities out of 283 in Japan, which involved 18 national and public university hospitals, 16 private university hospitals, 19 national and public hospitals, 18 private hospitals, 41 hygiene test institutes and 21 reagent manufacturers. Tests examined were on 6 substances related to functions of pituitary, 5 of thyroid function, 1 of parathyroid, 4 of digestive-pancreas, 5 of gonad-placenta, 4 of adrenal and 1 of renal-blood pressure regulation, on IgE, on digoxin and on 11 tumor-related substances. Tests were done on 2 - 3 samples supplied from the Committee and for reproducibility for within-day, between-day, effects of freeze-thaw and periodic variation after thawing. Methods involved those using non-radioisotopes like enzyme immunoassay as well as those using radioactive isotopes like radioimmunoassay. Results given by the mean, standard deviation and coefficient of variation for each kit, were analyzed for within-kit (between-facility) variation and between-kit (between-reagent) variation by one way analysis of variance. Findings were similar to those previously reported without the particular new problem; however, the committee considered that the survey should be done with human serum as a matrix especially for samples with a high matrix effect in future.

    Kobe city is located on the northern side of Osaka sedimentary basin, Japan, containing 1,000-2,000 m thick Quaternary sediments. After the Hanshin-Awaji Earthquake (January 17, 1995), a number of geological and geophysical surveys were conducted in this region. Then high-temperature anomaly of groundwater accompanied with high Cl concentration was detected along fault systems in this area. In addition, dissolved He in groundwater showed nearly upper mantle-like 3He/4He ratio, although there were no Quaternary volcanic activities in this region. Some recent studies have assumed that these groundwater profiles are related with geological structure because some faults and joints can function as pathways for groundwater flow, and mantle-derived water can upwell through the fault system to the ground surface. To verify these hypotheses, we established 3D geological and hydrological model around Osaka sedimentary basin. Our primary goal is to analyze spatial relationship between geological structure and groundwater profile. In the study region, a number of geological and hydrological datasets, such as boring log data, seismic profiling data, groundwater chemical profile, were reported. We converted these datasets to meshed data on the GIS, and plotted in the three dimensional space to visualize spatial distribution. Furthermore, we projected seismic profiling data into three dimensional space and calculated distance between faults and sampling points, using Visual Basic for Applications (VBA) scripts. All 3D models are converted into VRML format, and can be used as a versatile dataset on personal computer. This research project has been conducted under the research contract with the Japan Nuclear Energy Safety Organization (JNES).

    Typically, land use regression (LUR) models have been developed using campaign monitoring data rather than routine monitoring data. However, the latter have advantages such as low cost and long-term coverage. Based on the idea that LUR models representing regional differences in air pollution and regional road structures are optimal, the objective of this study was to evaluate the validity of LUR models for nitrogen dioxide (NO 2 ) based on routine and campaign monitoring data obtained from an urban area. We selected the city of Suita in Osaka (Japan). We built a model based on routine monitoring data obtained from all sites (routine-LUR-All), and a model based on campaign monitoring data (campaign-LUR) within the city. Models based on routine monitoring data obtained from background sites (routine-LUR-BS) and based on data obtained from roadside sites (routine-LUR-RS) were also built. The routine LUR models were based on monitoring networks across two prefectures (i.e., Osaka and Hyogo prefectures). We calculated the predictability of the each model. We then compared the predicted NO 2 concentrations from each model with measured annual average NO 2 concentrations from evaluation sites. The routine-LUR-All and routine-LUR-BS models both predicted NO 2 concentrations well: adjusted R 2 =0.68 and 0.76, respectively, and root mean square error=3.4 and 2.1ppb, respectively. The predictions from the routine-LUR-All model were highly correlated with the measured NO 2 concentrations at evaluation sites. Although the predicted NO 2 concentrations from each model were correlated, the LUR models based on routine networks, and particularly those based on all monitoring sites, provided better visual representations of the local road conditions in the city. The present study demonstrated that LUR models based on routine data could estimate local traffic-related air pollution in an urban area. The importance and usefulness of data from routine monitoring networks should be

Two vasculitis syndrome patients exhibited persistent symptoms and abnormal blood tests after treatment with conventional therapies.Methods: As the two cases had “blood stagnation” and “damps and heat” and one had a “yang deficiency” in terms of TCM theory, we applied certain selected Kampo medicines.Results: In case 1, the patient presented with hypereosinophilia, venous thrombosis, pulmonary infarction, decreased platelet count, ulner nerve palsy and Raynaud’s phenomena, which led to a diminished quality of life. After starting the Kampo medicines, the patient improved quickly and recovered within 11 months. In case 2, persistent purpura, abdominal pain, and bloody feces quickly improved and disappeared after Kampo treatment. After starting the Kampo medicines, prednisolone was stopped at 21 days without any sign of relapse to date.Conclusion: Kampo medicines helped clear the persistent abnormal symptoms and laboratory findings of vasculitis syndromes, Churg–Strauss syndrome and Henoch–Shönlein purpura, which had responded inadequately to the conventional therapies administered.Keywords: Kampo medicine, vasculitis, Churg–Strauss syndrome, Henoch–Shönlein purpura

Unmet needs for HCBS were defined as situations in which patients do not use or underuse HCBS despite needing them. Candidates for the factors relating to unmet needs for HCBS included three dimensions: predisposing, enabling, and need factors.Methods: Self-administrated questionnaires were collected from 391 CMs of DPHD certified with long-term care insurance. These were introduced by the dialysis facilities that a member of the Japanese Association of Dialysis Physicians belonged to. CMs were asked questions about their management of each individual case. HCBS included home help, visiting nursing, daycare, and short stay.Results: The prevalence of unmet needs for each HCBS ranged from 32% for home help to 48% for short stay. Barriers to service usage in the patients were associated with unmet needs for all four services. The patients with more severe cognitive malfunction were more likely to have unmet needs for visiting nursing and short stay. Heavier burden with caregiving was associated with more likelihood of unmet needs for home help and short stay

    In the UK and Japan, there is concern regarding rising rates of annual new HIV infections among Men who have Sex with Men (MSM). Whilst in the UK and Europe, gay businesses are increasingly recognized as being important settings through which to deliver HIV prevention and health promotion interventions to target vulnerable populations; in Japan such settings-based approaches are relatively underdeveloped. This article draws on qualitative data from a recently completed study conducted to explore whether it is feasible, acceptable and desirable to build on the recent European Everywhere project for adaptation and implementation in Japan. A series of expert workshops were conducted in Tokyo, Nagoya and Osaka with intersectoral representatives from Japanese and UK non-governmental organizations (NGOs), gay businesses, universities and gay communities (n = 46). Further discussion groups and meetings were held with NGO members and researchers from the Japanese Ministry of Health, Labour and Welfare's Research Group on HIV Prevention Policy, Programme Implementation and Evaluation among MSM (n = 34). The results showed that it is desirable, feasible and acceptable to adapt and implement a Japanese version of Everywhere. Such a practical, policy-relevant, settings-based HIV prevention framework for gay businesses may help to facilitate the necessary scale up of prevention responses among MSM in Japan. Given the high degree of sexual mobility between countries in Asia, there is considerable potential for the Everywhere Project (or its Japanese variant) to be expanded and adapted to other countries within the Asia-Pacific region. © The Author 2015.

    The energy driver development at the Institute of Laser Engineering (ILE), Osaka University, comprises three fields; glass, laser, carbon dioxide laser, and relativistic electron beam. The development of reliable glass lasers has been the main program at ILE. The GEKKO 12 module program was carried out in the fiscal years from 1977 to 1979 in order to develop various laser components and subsystems which are necessary to construct a 20 kJ GEKKO 12 glass laser. The measured gain coefficient of the 200 mm disk amplifier was 0.10/cm corresponding to the αD product of 4.0. The expected peak output power of the system was 2 TW at 0.1 ns and 0.9 kJ at 1 ns. The recent advances in coating techniques will enable to operate this system over 1.3 kJ per beam at 3 ns. Carbon dioxide lasers have been developed as efficient high energy lasers to study the wave length scaling of implosion process. The design and construction of the 10 kJ LEKKO 8 laser system are in progress. Relativistic electron beam machines, being the most cost-effective driver, have been studied to control pulsed power and to investigate electron beam plasma interaction. As the future plans of ILE, the construction of a 100 kJ energy driver from 1958 to 1987 for scientific break-even experiments is considered. (Kato, T.)

    Since the beginning of the 21st century, educating the next generation nuclear engineers have been an interest to groups, who were concerned of the recent decline in nuclear population in universities and industries. In June 2005, committee on education (CE) was established in AESJ (Atomic Energy Society of Japan), hoping to coordinate the groups related to nuclear education in Japan. The birth of CE was timely; because the importance of nuclear education was emphasized in 'Framework for Nuclear Energy Policy (Oct., 2005)' decided by the Atomic Energy Commission. In this paper, recent activities of CE, especially the proposals CE made related Framework for Nuclear Energy Policy, will be reported. The importance of the partnership with industries, government and academe will be emphasized. (author)

  11. METHODS OF FINDING BUSINESS PARTNERS OF MANUFACTURING FIRMS IN JAPAN

    Directory of Open Access Journals (Sweden)

    Nobuhiro Takahashi

    2017-09-01

    Full Text Available This paper addresses new methods of finding business partners for joint development in Japan. These methods create opportunities for a manufacturing firm, which has excellent technology, to find an appropriate business partner. We call these methods the Osaka model. In the model, a company finds a business partner among plenty of companies, while they establish mutual trust and solve higher levels of technological difficulties. The model shares strong points of both spot transaction and conventional co-development. In other words, this model takes advantages of both Western style and Japanese style inter-business relationship. This paper also argues the environment for encouraging the model. The area should be a place where you can obtain many sources of information. Increasing meetings or facilities on specific themes is an effective method to encourage the model in the area. In addition, a database with which each technological seed has been already arranged with their technological needs is beneficial for matching them. If such a database becomes a shared knowledge in the area, the model would be promoted.

    A familial form of Alzheimer disease recently was described in a kindred in Osaka, Japan. This kindred possesses an amyloid β-protein (Aβ) precursor mutation within the Aβ coding region that results in the deletion of Glu22 (ΔE22). We report here results of studies of [ΔE22]Aβ40 and [ΔE22]Aβ42 that sought to elucidate the conformational dynamics, oligomerization behavior, fibril formation kinetics, fibril morphology, and fibril stability of these mutant peptides. Both [ΔE22]Aβ peptides had extraordinary β-sheet formation propensities. The [ΔE22]Aβ40 mutant formed β-sheet secondary structure elements ≈400-fold faster. Studies of β-sheet stability in the presence of fluorinated alcohol cosolvents or high pH revealed that the ΔE22 mutation substantially increased stability, producing a rank order of [ΔE22]Aβ42 >Aβ42 > [ΔE22]Aβ40 > Aβ40. The mutation facilitated formation of oligomers by [ΔE22]Aβ42 (dodecamers and octadecamers) that were not observed with Aβ42. Both Aβ40 and Aβ42 peptides formed nebulous globular and small string-like structures immediately upon solvation from lyophilizates, whereas short protofibrillar and fibrillar structures were evident immediately in the ΔE22 samples. Determination of the critical concentration for fibril formation for the [ΔE22]Aβ peptides showed it to be ≈1/2 that of the wild type homologues, demonstrating that the mutations causes a modest increase in fibril stability. The magnitude of this increase, when considered in the context of the extraordinary increase in β-sheet propensity for the ΔE22 peptides, suggests that the primary biophysical effect of the mutation is to accelerate conformational changes in the peptide monomer that facilitate oligomerization and higher-order assembly.

    Human papillomavirus (HPV) 16 has previously been found in 19/41 breast carcinomas (46%) in women with a history of HPV 16 positive CIN III lesions. There was no significant difference in distribution of histological subtypes, mean or median tumour diameter or number of regional lymph node metastases in the HPV positive and HPV negative breast carcinoma groups. P53, p21 and c-erbB-2 proteins were analyzed by immunohistochemistry in the HPV 16 positive and HPV negative breast carcinomas. There was a significant difference in p53 and p21 protein immunoreactivity between HPV 16 positive and HPV negative breast carcinomas (p=0.0091 and p=0.0040), with a significant less detectable p53 and p21 protein immunoreactivity in the HPV 16 positive cases. There was also a significant difference in the coexpression of p53/p21 between the HPV 16 positive and HPV 16 negative breast carcinomas (p=0.002). No significant difference in immunostaining for c-erbB-2 protein in the two groups was found (p=0.15), or for the coexpression of p53/c-erbB-2 (p=0.19). The significantly lower expression of p53 and p21 proteins in HPV 16 positive than in HPV 16 negative breast carcinomas supports the hypothesis of inactivation and degradation of wild-type p53 proteins by HPV 16 E6 and that p53 mutation is not necessary for transformation in the HPV 16 positive cases.

    Third International Workshop on the Kanto Asperity Project; Chiba, Japan, 16-19 February 2008; The 1703 (Genroku) and 1923 (Taisho) earthquakes in Japan's Kanto region (M 8.2 and M 7.9, respectively) caused severe damage in the Tokyo metropolitan area. These great earthquakes occurred along the Sagami Trough, where the Philippine Sea slab is subducting beneath Japan. Historical records, paleoseismological research, and geophysical/geodetic monitoring in the region indicate that such great earthquakes will repeat in the future.

    An epidemiological survey of childhood autism as defined in ICD-10 Research Criteria was conducted in the northern part of Yokohama, Japan. The routine health checkup for 18-month-old children served as the initial mass-screening, and all facilities which provide child care services function to detect all cases with childhood autism and refer them to the Yokohama Rehabilitation Centre. Cumulative incidence of childhood autism up to 5 years of age among the birth cohort of 1988, and prevalence on 1 January 1994, among residents born in 1988 were estimated Cumulative incidence and prevalence were 16.2 per 10,000 and 21.1 per 10,000, respectively. Children with high-functioning autism who had IQs of 70 and over constituted approximately half of all the children with childhood autism. CONCLUSION. It was confirmed through better detection of high-functioning cases that childhood autism in Japan is more common than formerly estimated.

    The paper investigates relations between the damage caused by the Hyogo-ken Nanbu earthquake and the deep underground structures. A characteristic of the earthquake damage distribution is that the damage concentrated near faults. Most of the damages were seen on the side of faults` relatively falling rather than right above the faults and of their slightly slanting to the seaside. Distribution like this seems to be closely related to underground structures. Therefore, a distribution map of the depth of basement granite in Osaka sedimentary basin was drawn, referring to the data on basement rock depth obtained from the distribution map of gravity anomaly and the result of the survey using the air gun reflection method. Moreover, cubic underground structures were determined by 3-D gravity analysis. The result was concluded as follows: when observing the M7 zone of the low land, in particular, where the damage was great from an aspect of gravity anomaly, the basement rock below the zone declined near the cliff toward the sea, which indicates a great possibility of its being a fault. There is a high possibility that the zone suffered mostly from the damage caused by focusing by refraction and total reflection of seismic wave rays. 3 refs., 8 figs.

Generally, it takes several months to manufacture an influenza vaccine by propagation of the virus in chicken eggs or cultured cells. Newer, faster protocols for the production of vaccines that induce broad-spectrum immunity are therefore highly desirable. We previously developed human monoclonal antibody B-1 that shows broadly neutralizing activity against influenza A virus H3N2. B-1 recognizes an epitope region that includes an antiparallel β-sheet structure underneath the receptor binding site of influenza hemagglutinin (HA. In this study, the efficacy of a synthetic peptide vaccine derived from this epitope region against influenza A was evaluated. Materials and methods: Two peptides were synthesized, the upper and lower peptides. These peptides comprise amino acid residues 167–187 and 225–241, respectively, of the B-1 epitope region of HA, which is involved in

Patients older than 50 years with visual acuity worse than 20/40 or with whitish chorioretinal atrophy involving the macula were excluded. Two masked raters measured the choroidal thicknesses (CTs at the foveda, 3 mm superiorly, inferiorly, temporally, and nasally on the images and averaged the values. The second examination was about 365 days after the baseline examination. The CT reduction per year (CTRPY was defined as (CT 1 year after - baseline CT/days between the two examinations × 365. The retinal thicknesses were also investigated.Results: The CTRPY at the fovea was −1.0 ± 22.0 µm (range –50.2 to 98.5 at the fovea, –6.5 ± 24.3 µm (range −65.8 to 90.2 temporally, –0.5 ± 22.3 µm (range –27.1 to 82.5 nasally, –9.7 ± 21.7 µm (range –40.1 to 60.1 superiorly, and –1.4 ± 25.5 µm (range –85.6 to 75.2 inferiorly. There were no significant differences in the CTRPY at each location (P = 0.34. The CT decreased significantly (P < 0.05 only superiorly. The superior CTRPY was negatively correlated with the axial length (P < 0.05. The retinal thickness at the fovea did not change.

    A total of 752 fecal specimens collected during the period of July 2004 to June 2005 from infants and children with acute gastroenteritis from four different regions (Maizuru, Tokyo, Sapporo, and Osaka) of Japan were tested for the presence of norovirus by RT-PCR. It was found that 139 (18.5%) fecal specimens were positive for norovirus. Norovirus infection was detected almost all year round with the highest prevalence in January. Norovirus GII was the most predominant genogroup (98.6%; 137 of 139). The genotypes detected in this study were GI/1, GII/1, GII/3, GII/4, and GII/6. Of these, NoV GII/4 (known as the Lordsdale virus cluster) was re-emerging and became the leading genotype (77.7%). Meanwhile, the incidence of NoV GII/3 (known as the Arg320 virus cluster) has dropped rapidly, accounting for only 15.8%. Another interesting feature of the study was the identification of Picton03/AU-like recombinant NoV for the first time in Japan. Based on the genetic analysis, it was interesting to note that NoV GII/4 in 2004-2005 made a distinct cluster in comparison to other NoV GII/4 circulating in 2002-2003 and 2003-2004. Of note, "new recombinant variant designated GIIb" within NoV GII/3, which was first detected in Saga City, Japan in 2003-2004 in only one case, had increased, spreading widely in Japan and representing 45.5% (10 of 22). Further epidemiological studies should be conducted to determine whether this new recombinant variant strain will be dominant in Japan in the coming year.

    1989-01-01

    The number of the business establishments which utilize radiation with radioisotopes and radiation generators has continued to increase, and as of the end of March, 1989, it exceeded 4700. As to the state of utilization classified by districts, the use concentrates in large urban districts of Tokyo, Osaka, Kanagawa and Aichi, and the field of application spread to many fields of industries, agriculture, medical treatment and others. Recently, the utilization of radiation has become to be very highly advanced and diversified such as the medical diagnosis and treatment and the application to advanced technology using radiation generators. Now, the utilization of radiation is indispensable for national life and economical activities, but also the prevention of injury and the securing of safety are important. It is necessary to clarify the latest state of radiation utilization in Japan for the promotion of the production and utilization of radioisotopes and the prevention of radiation injury. In this book, the number of the business establishments using radiation and the state of utilization in medical, education and research, private enterprises and other fields, the state of distribution of radioisotopes, waste treatment, and radiation-related technicians are reported.

    The international and Japan's steel industry, the coking coal market, and Japan's expectations from Canada's coal industry are discussed. Japan's steel mills are operating at full capacity. Crude steel production for the first half of 2004 was 55.8 million tons. The steel mills are profitable, but costs are high, and there are difficulties with procuring raw materials. Japan is trying to enhance the quality of coke, in order to achieve higher productivity in the production of pig iron. Economic growth is rising disproportionately in the BRICs (Brazil, Russia, India, and China), with a large increase in coking coal demand from China. On the supply side, there are several projects underway in Australia and Canada to increase production. These include new developments by Elk Valley Coal Corporation, Grande Cache Coal, Western Canadian Coal, and Northern Energy and Mining in Canada. The Elga Mine in the far eastern part of Russia is under development. But the market is expected to remain tight for some time. Japan envisions Canadian coal producers will provide a stable coal supply, expansion of production and infrastructure capabilities, and stabilization of price. 16 slides/overheads are included.

    We present recent results on the hydrodynamic instability experiments on the HIPER (High Intensity Plasma Experimental Research) laser facility at ILE, Osaka University. We measured the Rayleigh-Taylor growth rate on the HIPER laser. Also measured were all parameters that determine the RT growth rate. We focused on the measurements of the ablation density of laser-irradiated targets, which had not been experimentally measured. The experimental results were compared with calculations with one dimensional simulation coupled with Fokker-Planck equation for electron transport. (author)

    On the occasion of installing the γ-ray irradiation system for animal experiments at the Radioisotope Research Center of Osaka University both lead collimators and shield screen have been supplemented to the system in order to satisfy the Japanese legal regulation that the dose equivalent rate outside the controlled area should be less than 300 μSv/w because the experimental room has not been so designed as to install such an apparatus. The original use of the system is to study the internal β-ray exposure of a small animal on a dosage of tritium water, which will be eliminated from a body with a biological half-life. Accordingly, the dose rate of internal exposure due to β-ray will change with time, and hence such a situation could be simulated with an external exposure due to γ-rays by changing the dose rate spatially, that is, the distance between the γ-ray source and a sample. It is, however, anticipated that improvement of the system would bring increase in the scattered γ-rays at an irradiation point and hence it becomes the purpose of the present paper to obtain precise exposures including scattered γ-rays at each irradiation point for animal experiments and also to find an optimum point for standard calibration where no scattered γ-rays are observed. For that purpose the effect of them will be evaluated with both calculations due to the Monte Carlo code for neutron photon transport (MCNP) and experiments due to the ionization chamber calibrated at the National Bureau of Standard in Japan.

    Although Japan has been considered to have little lead (Pb) pollution in modern times, the actual pollution situation is unclear. The present study aims to investigate the extent of Pb pollution and to identify the pollution sources in Japan using stable Pb isotope analysis with kidneys of wild rats. Wild brown ( Rattus norvegicus , n = 43) and black ( R. rattus , n = 98) rats were trapped from various sites in Japan. Mean Pb concentrations in the kidneys of rats from Okinawa (15.58 mg/kg, dry weight), Aichi (10.83), Niigata (10.62), Fukuoka (8.09), Ibaraki (5.06), Kyoto (4.58), Osaka (4.57), Kanagawa (3.42), and Tokyo (3.40) were above the threshold (2.50) for histological kidney changes. Similarly, compared with the previous report, it was regarded that even structural and functional kidney damage as well as neurotoxicity have spread among rats in Japan. Additionally, the possibility of human exposure to a high level of Pb was assumed. In regard to stable Pb isotope analysis, distinctive values of stable Pb isotope ratios (Pb-IRs) were detected in some kidney samples with Pb levels above 5.0 mg/kg. This result indicated that composite factors are involved in Pb pollution. However, the identification of a concrete pollution source has not been accomplished due to limited differences among previously reported values of Pb isotope composition in circulating Pb products. Namely, the current study established the limit of Pb isotope analysis for source identification. Further detailed research about monitoring Pb pollution in Japan and the demonstration of a novel method to identify Pb sources are needed.

    This paper reports a sea bottom gravity survey conducted with an objective to identify deep underground structure in the vicinity of the epicenter of the Hyogoken-Nanbu Earthquake. The surveyed areas are the whole Osaka Bay area north of the north latitude of 34 degrees and 20 minutes, and the eastern part of the Sea of Harima east of the east longitude of 134 degrees and 40 minutes, excluding the areas difficult of performing measurements. A square lattice with sides each about 2 km was arranged with 408 measurement points. The measurement was carried out by using an observation vessel mounted with a sea bottom gravimeter made by LaCoste and Romberg Corporation, which was lowered down to the sea bottom at the measurement points. Errors in positions and water depths at the gravity measuring points were suppressed to less than 0.002 minutes and 0.1 m, respectively. The measurement data were given necessary corrections by using a unified method applicable also to land areas, and a Bouguer anomaly chart was prepared. Based on the chart, this paper summarizes features in the Bouguer anomaly in the surveyed areas (such as the low-gravity anomaly band extending the central part of the Osaka bay from north-east to south-west, and the gradient structure existing on the Awaji island side). 6 refs., 1 fig.

    Full Text Available At the beginning of the 21st century, the new economic order settled at international level is based on the intensification of the activities of multinational companies (MNC on global markets. Japan – the third world economy in 2010 – registers outstanding economic results due to its strong connection to the current of the globalization of international affairs. The issue of understanding the key role of Japanese MNCs in international business received a great deal of attention in recent years. We found that Japanese firms expanded their overseas production from 3.1% in 1986 to 16.3% in 2005 and 17% in 2009. Although MNCs are a minority in terms of the number of firms, they nevertheless dominate the Japanese trade. In recent years, Japanese firms have become more active in developing overseas activities by establishing local subsidiaries and acquiring local companies. Therefore, cross-border Mergers & Acquisitions (M&A appeared to be a very useful tool through which Japanese MNCs expanded their tentacles worldwide. Despite the devastating effects of the great East Japan Earthquake, statistical data released by UNCTAD show that Japan will again be, on the long run, a leading investor for outward FDI. Therefore, Japanese MNCs will continue to play a key role within international business environment.

    In April 2008, the specialization in departments of obstetrics and gynecology was conducted in Sennan area of Osaka prefecture in Japan, which aims at solving the problems of regional provision of obstetrical service. Under this specialization, the departments of obstetrics and gynecology in two city hospitals were combined as one medical center, whilst one hospital is in charge of the department of gynecology and the other one operates the department of obstetrics. In this paper, we implement a cost-benefit analysis to evaluate the validity of this specialization. The benefit-cost ratio is estimated at 1.367 under a basic scenario, indicating that the specialization can generate a net benefit. In addition, with a consideration of different kinds of uncertainty in the future, a number of sensitivity analyses are conducted. The results of these sensitivity analyses suggest that the specialization is valid in the sense that all the estimated benefit-cost ratios are above 1.0 in any case.

    As in other countries, the traditional doctor-patient relationship in the Japanese healthcare system has often been characterised as being of a paternalistic nature. However, in recent years there has been a gradual shift towards a more participatory-patient model in Japan. With advances in technology, the possibility to use digital technologies to improve patient interactions is growing and is in line with changing attitudes in the medical profession and society within Japan and elsewhere. The implementation of an online patient engagement platform is being considered by the Myotonic Dystrophy Registry of Japan. The aim of this exploratory study was to understand patients' views and attitudes to using digital tools in patient registries and engagement with medical research in Japan, prior to implementation of the digital platform. We conducted an exploratory, cross-sectional, self-completed questionnaire with a sample of myotonic dystrophy (MD) patients attending an Open Day at Osaka University, Japan. Patients were eligible for inclusion if they were 18 years or older, and were diagnosed with MD. A total of 68 patients and family members attended the Open Day and were invited to participate in the survey. Of those, 59 % submitted a completed questionnaire (n = 40). The survey showed that the majority of patients felt that they were not receiving the information they wanted from their clinicians, which included recent medical research findings and opportunities to participate in clinical trials, and 88 % of patients indicated they would be willing to engage with digital technologies to receive relevant medical information. Patients also expressed an interest in having control over when and how they received this information, as well as being informed of how their data is used and shared with other researchers. Overall, the findings from this study suggest that there is scope to develop a digital platform to engage with patients so that they can receive

    This study was conducted to determine the prevalence and characteristics of Listeria monocytogenes in bovine colostrum in Japan. We collected bovine colostrum samples from 210 dams from 21 dairy farms in Hokkaido prefecture (Japan) between March and June 2009. L. monocytogenes was detected in samples from 6 (28.6%) of the 21 farms. Of the 210 samples, 16 (7.6%) were positive for L. monocytogenes. We recovered 80 L. monocytogenes isolates; 44 (55%) isolates were classified as serotype 1/2b and 36 (45%) were classified as serotype 4b. The isolates were susceptible to penicillin, ampicillin, amoxicillin, gentamicin, kanamycin, streptomycin, erythromycin, vancomycin, tetracycline, chloramphenicol, ciprofloxacin, and trimethoprim-sulfamethoxazole. Pulsed-field gel electrophoresis (PFGE) characterization of the 80 isolates revealed six PFGE types. Two PFGE types corresponded to human listeriosis cases. Most L. monocytogenes isolates possessed virulence-associated genes (actA, hly, iap, inlA, inlC, mpl, plcA, plcB, opuCA, prfA, and clpC). One PFGE type isolate possessed an epidemic clone II marker. Our findings suggest that isolates from bovine colostrum have the potential to cause human and animal listeriosis. This is the first study on the prevalence and characteristics of L. monocytogenes isolated from bovine colostrum obtained from dairy farms. Our results have important implications for improving public health and elucidating the epidemiology of L. monocytogenes in bovine colostrum.

Here, using a nanobeacon, the surface of which was fabricated with peanut agglutinin as TF-binding molecules, we demonstrate that the nanobeacon is able to detect TF antigen in frozen and freshly biopsied polyps using fluorescence microscopy. Our results provide important clues about how to detect aberrant colonic tissues in the most timely fashion. Given the versatile application method for this topical nanobeacon, the protocol used in this work is amenable to clinical colonoscopy. Moreover, the prospects of clinical translation of this technology are evident. Keywords: TF antigen

Previous research has seldom assessed the relationship between the severity of physical symptoms and the severity of mental and emotional symptoms of depression or other health outcomes, and no such studies have been conducted previously among individuals with depression in Japan. The aim of this study was to assess the relationship between the severity of physical pain and depression and other outcomes among individuals in Japan diagnosed with depression.Methods: Data for individuals aged 18 and older in Japan who reported being diagnosed with depression and also reported physical pain were obtained from the Japan National Health and Wellness Survey. These respondents were characterized on sociodemographics and health characteristics, and the relationship between ratings of severity on pain in the last week and health outcomes were assessed using bivariate correlations and generalized linear models. Measures included the Patient Health Questionnaire for depression severity, Medical Outcomes Study 12-Item Short Form Survey Instrument for health-related quality of life, the Work Productivity and Activity Impairment for work and activity impairment, and 6-month report of health care use.Results: More severe physical pain in the past week was correlated with more severe depression, worse health-related quality of life, lower health utility, greater impairment at work, and more health care provider visits. These relationships remained significant after incorporating sociodemographics and health characteristics in the statistical models

    The results of the 16th quality control survey for radioisotope in vitro tests in Japan (1994) are summarized. Of 399 medical facilities conducting radioisotope in vitro tests, 201 were enrolled in this study. Forty items including ACTH and {alpha}-fetoprotein were selected as the subjects. Freeze-drying samples were sent to the facilities. The quality of assay tubes, duration between fusion of the samples and assay, and the condition of preservation were examined, and those influence on the assay values were studied. Radioimmunoassay, immunoradiometric assay, and other procedures using enzymes, fluorescence, and chemiluminescense were conducted. The assay values of some of the items were significantly influenced by repeated freezing and fusion of the samples. Data were collected from individual items and kits used, and analyzed. The significant difference of values between different facilities and kits used were considered due to difference of assay principle, antibodies used, and standard items. The concentration of the samples needs to be improved. (S.Y.).

    This paper explains the involvement of the global environment action plan of Japan Society of Civil Engineers, Agenda 21, with civil engineerings and global environmental problems, as well as the global environment action plan. Global environmental problems require handling the matters in three ways: identification and elucidation of events, effect analysis estimation, and alleviation, avoidance and prevention of the effect. Settlement and proliferation of civil engineering technologies transferred to developing countries demand indispensably understanding such features of the developing countries as social and economic conditions, natural conditions, climates, histories, races, and cultures. Realizing the sustainable development requires the followings: formation of civil engineerings that contribute to improving global environments; development of civil engineerings that make coexistence of human being and other living organisms possible; analyses of effects and mechanisms of global warming and weather change and the corresponding technique and system development; and development of techniques to build resource circulating type national land and cities. It is also essential to move forward positively structuring civil engineerings that contribute to solving such global environmental problems as acid rains and marine pollution, and technical development thereof; providing guidelines on execution of international civil engineering constructions, and technical development thereof; developing civil engineerings in developing countries and assisting training of people.

    This project aims to do research on forecasts of energy demand structure and electricity generation cost in each power plant in Japan in the 21st century, considering constructing successful FBR scenario. During the process of doing research on forecasts of energy demand structure in Japan, documents published from organizations in inside and outside of Japan were collected. These documents include prospects of economic growth rate, forecasts of amount for energy supply and demand, the maximum amount of introducing new energy resources, CO2 regulation, and evaluation of energy best mixture. Organizations in Japan such as Economic Council and Japan Energy Economic Research Institute have provided long-term forecasts until the early 21st century. Meanwhile, organizations overseas have provided forecasts of economic structure, and demand and supply for energy in OECD and East Asia including Japan. In connection with forecasts of electricity generation cost in each power plant, views on the ultimate reserves and cost of resources are reviewed in this report. According to some views on oil reserves, making assumptions based on reserves/production ratio, the maximum length of the time that oil reserves will last is 150 years. In addition, this report provides summaries of cost and potential role of various resources, including solar energy and wind energy; and views on waste, safety, energy security-related externality cost, and the price of transferring CO2 emission right.

    In Osaka, Uemachi Fault is one of the famous active faults. It across the center of Osaka and lies in N-S direction mainly and is more than 40 km in length. The faults bound sedimentary basins, where thick sedimentary deposits of the Pliocene-Quaternary Osaka Group have accumulated. The deposits consist primarily of sand and marine and non-marine clay, and the clay layers are key markers for the interpretation of glacial and interglacial cycles. In this study, we estimate the width of the flexure zone using a geotechnical borehole database. GI database collects more than 40,000 boreholes and includes both geological information and soil properties around Osaka by the Geo-database Information Committee of Kansai Area. Our results indicate that the deformation associated with the flexure zone is distributed primarily along the splay fault (NE-SW) and not along the main fault, suggesting that the splay fault might be the primary fault at present. We first examined the borehole data along the seismic reflection line and then considered the surrounding area. An Upper Pleistocene marine clay (Ma12) is a good indicator of the flexure zone. We constructed many cross sections in and around the fault zone and classified the deformation form into three categories around the flexure zone. The results of this study allowed us to map the distribution of folding in a zone in the west of the Osaka area. Folding can be classified into three types: (1) Ma12 folding, (2) Ma12 folding that does not continue toward the hanging wall, and (3) folding or displacement of old marine clay. These folding zone trends are N-W strike however these trace are serpentine. These folding zone information are not in worth to estimate the source fault, however these zone will be more serious damaged when the earthquake occurred. Our result agrees well with the average displacement speed of about 0.4 m/ka that was derived by the Headquarters for Earthquake Research Promotion of the Ministry of Education

  7. The gas industry in Japan

    Though oil is the most widely used primary energy in Japan, its market share is decreasing steadily in favour of other energies such as natural gas. Around 80 % of the gas consumed in Japan is imported in the form of LNG, with locally produced natural gas accounting for 5 % and LPG 12%. Annual LNG supplies now total 48 million tons (720 TWh) and are forecast to rise to 57 million tons over the next ten years. However, only on third of the total volume of LNG, i.e., 242 TWh, is distributed to final consumers. The rest is imported directly by power companies to produce electricity. The 245 gas distribution companies, 70 in the public sector and 175 in the private sector (including three large firms: Tokyo Gas, Osaka Gas and Toho Gas) carry the gas through their own non-interconnected networks to around 25 million customers, though the gas supply area covers only 5 % of the country. This small percentage can be explained partly by Japan's topography: 80 % of the land is covered by mountains. This means that only 20 % of the country is suitable for industrial and residential development. Populations living outside the gas supply areas mainly use LPG. The number of LPG customers totals around 25 million, a similar number to those using mains gas. However, the share of mains gas is increasing each year due to the population increase in urban zones. Though gas represents only 11 % of the energy consumed in Japan, it is nevertheless present on practically all markets and holds the leading position for domestic hot water and cooking in the residential sector. However, for heating, it lags well behind oil. In industry, mains gas covers only 5% of energy needs. However, with the expansion of the pipeline network and market liberalization, the share of gas is set to increase. The price of gas for the residential sector is 2 to 3 times higher than in western countries. This can be attributed to the following factors: most natural gas is imported LNG; unit consumption in the

    The 70-year history of scientific endeavor of solid state ionics research in Japan is reviewed to show the contribution of Japanese scientists to the basic science of solid state ionics and its applications. The term 'solid state ionics' was defined by Takehiko Takahashi of Nagoya University, Japan: it refers to ions in solids, especially solids that exhibit high ionic conductivity at a fairly low temperature below their melting points. During the last few decades of exploration, many ion conducting solids have been discovered in Japan such as the copper-ion conductor Rb4Cu16I7Cl13, proton conductor SrCe1-xYxO3, oxide-ion conductor La0.9Sr0.9Ga0.9Mg0.1O3, and lithium-ion conductor Li10GeP2S12. Rb4Cu16I7Cl13 has a conductivity of 0.33 S cm-1 at 25 °C, which is the highest of all room temperature ion conductive solid electrolytes reported to date, and Li10GeP2S12 has a conductivity of 0.012 S cm-1 at 25 °C, which is the highest among lithium-ion conductors reported to date. Research on high-temperature proton conducting ceramics began in Japan. The history, the discovery of novel ionic conductors and the story behind them are summarized along with basic science and technology.

    The activities of direct drive implosion experiments at ILE of Osaka Univ. are focused on the planar- and spherical-target experiments relating to Rayleigh-Taylor instability and the implosion experiments of cryogenic targets with low density plastic foam shell overcoated by a solid plastic layer. In the spherical shell target implosions a very early x-ray emission (refer as pre-emission hereafter) has been observed at the center of the target. The appearance of the pre-emission is related to the illumination nonuniformity. The appearance time of the pre-emission, the electron temperature of the source plasma of the pre-emission and the possibility of Rayleigh-Taylor instability have been studied experimentally to understand the mechanism of the pre-emission. Shell break up by Rayleigh-Taylor instability has been concluded to be the most probable mechanism of the pre-emission

    Full Text Available Yoshinobu Mizuno, Masakazu Yamada, Chika ShigeyasuDivision for Vision Research, National Institute of Sensory Organs, National Tokyo Medical Center, Tokyo, JapanOn behalf of The Dry Eye Survey Group, National Hospital Organization of JapanBackground: This study was performed to estimate the annual direct cost incurred by dry eye patients, which includes expenses for treatment and drugs, as well as the cost of punctal plugs.Methods: The study group consisted of 118 dry eye patients aged 20 years or older who visited any of the 15 medical care facilities that participated in this prospective cohort dry eye study. We estimated annual direct costs from outpatient medical records and survey questionnaires obtained from patients. Results: Of the total patients enrolled, 10 were men and 108 women, and their average age was 64.1 ± 11.2 years. The number of hospital visits made by patients was 5.8 ± 3.6 per year. Among those who used ophthalmic solutions, the numbers of bottles used per year were as follows: 32.1 ± 20.8 bottles of hyaluronic acid ophthalmic solution (87 patients, 53.1 ± 42.2 bottles of artificial tears (40 patients, and 33.2 ± 23.2 bottles of over-the-counter eyedrops (15 patients. In patients with punctal plugs, 4.1 ± 3.9 plugs were used annually. The annual drug cost was 32,000 ± 21,675 Japanese yen (323 ± 219 US dollars. The clinical cost was 16,318 ± 9961 Japanese yen (165 ± 101 US dollars. The total direct costs including punctal plug treatment amounted to 52,467 ± 38,052 Japanese yen (530 ± 384 US dollars. Conclusion: Although treatment modalities for dry eye in Japan were different from those in the US and in European countries, the direct cost of dry eye patients in Japan was comparable with that reported in those countries. Considering the high prevalence of dry eye, the direct cost of this chronic condition may be significant.Keywords: burden of disease, cost, dry eye, eyedrops, quality of life

    Full Text Available Presently, the total number of archaeological obsidian sources in Japan is more than 80, and among them, 21 are in Hokkaido, northern part of the Japanese archipelago (Izuho and Sato 2007. Obsidian was the dominant of lithic raw material in the Upper Paleolithic Hokkaido (35-10 ka cal BP. Out of 21 archaeological obsidian sources in Hokkaido, 4 sources: Shirataki, Oketo, Tokachi, and Akaigawa are the major obsidian sources and the others are minor sources. Shirataki is one of the largest obsidian sources in Northeast Asia and it is well known that Shirataki obsidian was transported outside Hokkaido to Sakhalin and the Paleo-Honshu Island from the Late Upper Paleolithic period.We compiled data of obsidian source analyses conducted to artefacts from Paleolithic sites in Hokkaido, and it became clear that the ratio of Shirataki obsidian in all analyzed materials is more than half (Sato and Yakushige in press.We examined how far Shirataki obsidian was transported in each period: the Early Upper Paleolithic (35-25 ka cal BP and the Late Upper Paleolithic (25-10 ka cal BP. The Late Upper Paleolithic is divided into three stage, the early Early Microblade Industry (Stage 1: 25-21 ka cal BP, the late Early Microblade Industry (Stage 2: 19-16 ka cal BP, and the Late Microblade Industry (Stage 3: 16-10 ka cal BP. As a result, it is revealed that the distribution areas of Shirataki obsidian did not expand gradually over time, but are different in different lithic industries. In the background of this situation lay the difference of ecological adaptation strategies adopted by the prehistoric people of the time and their movement behavioral strategies.

    Cisplatin-based chemotherapy has been widely used in a neoadjuvant as well as adjuvant setting. Furthermore, trimodal approaches including complete transurethral resection of the bladder tumor followed by combined chemotherapy and radiation have generally been performed as bladder preservation therapy. However, none of the protocols have achieved a 5-year survival rate of more than 70%. Additionally, the toxicity of chemotherapy and/or a decreased quality of life due to urinary diversion cannot be ignored, as most patients with bladder cancer are elderly. We therefore newly developed the novel trimodal approach of ''combined therapy using balloon-occluded arterial infusion of anticancer agent and hemodialysis with concurrent radiation, which delivers an extremely high concentration of anticancer agent to the site of a tumor without systemic adverse effects (''Osaka Medical College regimen'' referred to as the OMC regimen). We initially applied the OMC regimen as neoadjuvant chemotherapy for locally advanced bladder cancer. However, since more than 85% of patients with histologically-proven urothelial cancer achieved complete response with no evidence of recurrence after a mean follow-up of 170 (range 21-814) weeks, we have been applying the OMC-regimen as a new approach for bladder sparing therapy. We summarize the advantage and/or disadvantage of chemotherapy in neoadjuvant as well as adjuvant settings, and show the details of our newly developed bladder sparing approach OMC regimen in this review.

New radiosensitizers and cytotoxic or cytostatic agents, and innovative techniques of drug delivery are still under investigation.Methods: Five patients with brain metastases who did not respond to whole-brain radiotherapy and then received bevacizumab combined with paclitaxel were identified using our database of records between 2011 and 2012. The clinicopathological data and outcomes for these patients were then reviewed.Results: The median time to disease progression was 86 days. Of five patients, two (40% achieved a partial response, two had stable disease, and one had progressive disease. In addition, one patient with brain metastases had ptosis and diplopia due to metastases of the right extraocular muscles. However, not only the brain metastases, but also the ptosis and diplopia began to disappear after 1 month of treatment. The most common treatment-related adverse events (all grades were hypertension (60%, neuropathy (40%, and proteinuria (20%. No grade 3 toxicity was seen. No intracranial hemorrhage was observed.Conclusion: We present five patients with breast cancer and brain metastases, with benefits from systemic chemotherapy when combined with bevacizumab.Keywords: brain, bevacizumab, metastatic breast cancer

The conservative management protocol consisted of the application of warm compresses and massage over the mass, with the addition of antibiotics when dacryocystitis developed. Patient age at the time of resolution, presence of retrograde outflow of contents of dacryocystoceles from the puncta, and development of dacryocystitis were recorded.Results: The dacryocystocele was unilateral in four patients and bilateral in one patient. A nasal cyst was present in four patients without respiratory distress. The median patient age at the time of the diagnosis was 7 days (range 2–10 days. Conservative management was selected in all patients, and the dacryocystocele was resolved in all patients at a median patient age of 14.5 days (range 11–105 days. Two sides developed dacryocystitis, which resolved in a few days with antibiotic treatment. In those two sides, rupture of the dacryocystoceles to the common canaliculus with retrograde discharge of the contents from the puncta before the dacryocystitis developed was noted. For the other four treated sides, no such discharge or development of dacryocystitis was observed.Conclusion: The findings of this study show that a dacryocystocele has a good chance of resolving spontaneously with conservative management and careful observation, and that rupture of the dacryocystocele to the common canaliculus might be an important precursor of dacryocystitis.Keywords: dacryocystitis, congenital lacrimal obstruction, remnant, precursor, retrograde

    To estimate the prevalence and risk factors of urinary and fecal incontinence among a community-residing older population in Japan. Population-based cross-sectional study. A randomly selected sample of 1473 people aged 65 years and older living in the City of Settsu, Osaka, in 1992. Data collected via in-home visits were used to estimate the prevalence of urinary and fecal incontinence and to provide information regarding potential risk factors of urinary and fecal incontinence. Data were obtained from 1405 older adults, a response rate of 95.4%. The prevalence of any degree of urinary incontinence was 98/1000 in both sexes, and 87/ 1000 men and 66/1000 women admitted to some degree of fecal incontinence. Daily, 34/1000 and 20/1000 of the population were incontinent of urine and feces, respectively. There was an increasing prevalence of urinary and fecal incontinence with age in both sexes, but the expected greater prevalence in women was not found. By univariate analyses, age older than 75 years, poor general health as measured by Activities of Daily Living, stroke, dementia, no participation in social activities, and lack of life worth living (Ikigai) were associated significantly with both urinary and fecal incontinence. In the multivariate analyses using logistic regression, age older than 75 years, poor general health, and stroke were independent risk factors for any type of incontinence. Diabetes was an independent risk factor for isolated fecal incontinence, and dementia and no participation in social activities were independent risk factors for double incontinence. Incontinence of urine and feces is a prevalent condition among very old people living in the community in Japan and is associated highly with health and psychosocial conditions.

    The regenerative capacity of muscle dramatically decreases with age because old muscle stem cells fail to proliferate in response to tissue damage. Here we uncover key age-specific differences underlying this proliferative decline: namely, the genetic loci of CDK inhibitors (CDKI) p21 and p16 are more epigenetically silenced in young muscle stem cells, as compared to old, both in quiescent cells and those responding to tissue injury. Interestingly, phosphorylated ERK (pERK) induced in these cells by ectopic FGF-2 is found in association with p21 and p16 promoters, and moreover, only in the old cells. Importantly, in the old satellite cells FGF-2/pERK silences p21 epigenetically and transcriptionally, which leads to reduced p21 protein levels and enhanced cell proliferation. In agreement with the epigenetic silencing of the loci, young muscle stem cells do not depend as much as old on ectopic FGF/pERK for their myogenic proliferation. In addition, other CDKIs, such asp15INK4B and p27KIP1, become elevated in satellite cells with age, confirming and explaining the profound regenerative defect of old muscle. This work enhances our understanding of tissue aging, promoting strategies for combating age-imposed tissue degeneration. PMID:25447026

  4. Nuclear power development in Japan

    2000-01-01

    This article describes the advantages of nuclear energy for Japan. In 1997 the composition of the total primary energy supply (TPES) was oil 52.7%, coal 16.5%, nuclear 16.1% and natural gas 10.7%. Nuclear power has a significant role to play in contributing to 3 national interests: i) energy security, ii) economic growth and iii) environmental protection. Energy security is assured because a stable supply of uranium fuel can be reasonably expected in spite of dependence on import from abroad. Economic growth implies the reduction of energy costs. As nuclear power is capital intensive, the power generation cost is less affected by the fuel cost, therefore nuclear power can realize low cost by favoring high capacity utilization factor. Fossil fuels have substantial impacts on environment such as global warming and acid rain by releasing massive quantities of CO 2 , so nuclear power is a major option for meeting the Kyoto limitations. In Japan, in 2010 nuclear power is expected to reach 17% of TPES and 45% of electricity generated. (A.C.)

    The Research Reactor Institute, Kyoto University (KURRI) has more than 250 MTR-type HEU spent fuel elements. They have been stored in water pools after irradiation in the Kyoto University Research Reactor (KUR) core. The longest pool residence time is 25 years. In accordance with the Foreign Research Reactor Spent Nuclear Fuel Receipt Program of the United States, sixty KUR spent fuel elements were shipped from KURRI to the Savannah River Site of the USDOE in August, 1999. This shipment was done successfully through a public port in Osaka Prefecture, Japan. This is the first shipment in the past twenty-six years after the last shipment through the Yokohama Port. Concerning the use of a public port, we had to solve many issues for public acceptance. In this paper, we describe how we have stored the spent fuels for a long time with high integrity and how we have obtained public acceptance for the transport. (author)

    Japan has shown tremendous economic growth in the post-war period and is now one of the world's leading industrial countries. Japan has virtually no domestic oil or natural gas reserves and is the second-largest net importer of crude oil and largest net importer of liquefied natural gas in the world. Including nuclear power, Japan is only 16% energy self-sufficient (neglecting uranium imports). Japan's total primary energy demand in 2007 was 514 Mtoe. Oil is the most consumed energy resource in Japan (45% as of 2007), although its share of total energy consumption has strongly declined from 57% in 1990. Coal, with 22% (versus 17% in 1990), continues to account for a significant share of total energy consumption, although 99% of the coal must be imported. Natural gas (16%) and nuclear power (13%) are increasingly important sources. Total electricity production in Japan amounted to 1123 TW.h in 2007, with the largest share of 35% (up from 20% in 1990) from natural gas. The share of nuclear power is 32%, followed by coal (28%), oil (19%), hydro (9%) and other renewables (3%).

  8. Empowered? Evaluating Japan's national energy strategy under the DPJ administration

    In August 2009, after 54 years of virtually unbroken rule, Japan's Liberal Democratic Party (LDP) was ousted from power by the Democratic Party of Japan (DPJ). The DPJ's campaign platform included a pledge to facilitate extreme reductions in greenhouse gas (GHG) emissions. Yet, at the COP16 meeting in Cancun, Japan announced that it would not accept further emission reduction targets without broader commitment from all nations. This paper seeks to explain this dichotomy by employing a targeted stakeholder evaluation based on surveys with 321 Japanese citizens to assess the extent to which influential stakeholder groups in Japan supports a potentially costly transition to a low-carbon energy infrastructure amidst severe economic challenges that the nation faces. Findings help explain Japan's adversarial role in COP16 negotiations in Cancun, despite the stated GHG reduction ambitions of Japan's current ruling party. The analysis concludes that if the DPJ does embrace aggressive CO 2 reduction targets in the future, the strategic focus will likely mirror the former ruling party's energy policy of bolstering nuclear power generation capacity and promoting energy efficiency improvements while exhibiting lukewarm commitment to supporting capacity development in alternative sources of energy supply such as solar panels and wind turbines. - Research highlights: → Public consensus exists regarding which energy policy goals are important in Japan. → Minor perceptual differences are not of a catalytic nature. → Public consensus does not deviate significantly from past LDP energy policy. → Unlikely that the DPJ will pursue costly energy transition initiatives. → Likely that the DPJ energy strategy will be substantively similar to LDP strategy. → Any differences in strategy will focus on CO 2 reduction magnitude not substance.

  9. The steroid metabolite 16(β)-OH-androstenedione generated by CYP21A2 serves as a substrate for CYP19A1.

    The 21-hydroxylase (CYP21A2) is a steroidogenic enzyme crucial for the synthesis of mineralo- and glucocorticoids. It is described to convert progesterone as well as 17-OH-progesterone, through a hydroxylation at position C21, into 11-deoxycorticosterone (DOC) and 11-deoxycortisol (RSS), respectively. In this study we unraveled CYP21A2 to have a broader steroid substrate spectrum than assumed. Utilizing a reconstituted in vitro system, consisting of purified human CYP21A2 and human cytochrome P450 reductase (CPR) we demonstrated that CYP21A2 is capable to metabolize DOC, RSS, androstenedione (A4) and testosterone (T). In addition, the conversion of A4 rendered a product whose structure was elucidated through NMR spectroscopy, showing a hydroxylation at position C16-beta. The androgenic properties of this steroid metabolite, 16(β)-OH-androstenedione (16bOHA4), were investigated and compared with A4. Both steroid metabolites were shown to be weak agonists for the human androgen receptor. Moreover, the interaction of 16bOHA4 with the aromatase (CYP19A1) was compared to that of A4, indicating that the C16 hydroxyl group does not influence the binding with CYP19A1. In contrast, the elucidation of the kinetic parameters showed an increased K m and decreased k cat value resulting in a 2-fold decreased catalytic efficiency compared to A4. These findings were in accordance with our docking studies, revealing a similar binding conformation and distance to the heme iron of both steroids. Furthermore, the product of 16bOHA4, presumably 16-hydroxy-estrone (16bOHE1), was investigated with regard to its estrogenic activity, which was negligible compared to estradiol and estrone. Finally, 16bOHA4 was found to be present in a patient with 11-hydroxylase deficiency and in a patient with an endocrine tumor. Taken together, this study provides novel information on the steroid hormone biosynthesis and presents a new method to detect further potential relevant novel steroid metabolites

    The present study is the first to show overall prevalences of intestinal parasites among breeding kennel dogs in Japan. A total of 573 fresh fecal samples were collected from dogs at 12 breeding kennels. Giardia-specific coproantigen was examined by ELISA kit (SNAP(®) Giardia, IDEXX Laboratories, Inc., Maine, USA). Other intestinal parasites were determined microscopically using the formalin-ethyl acetate sedimentation technique. Overall prevalences of two genera of protists, Giardia spp. and Cystoisospora spp., were 25.7 and 1.2 %, respectively. The prevalence of helminthes was recorded as: Toxocara canis 0.2 %, Toxascaris leonina 0.9 %, Ancylostoma caninum 0.2 %, Trichuris vulpis 2.1 %, and Spirometra erinacei 0.4 %. According to age categories, Giardia spp., Cystoisospora spp., and T. leonina in parasite infections were found at the high prevalent, ranging from 16.0 to 70.0 %.

    Nuclear power generated by light water reactors accounts for approximately 1/3 of Japan's power supply. Development of the Advanced Pressurized Water Reactor (APWR) was initiated by five PWR electric power companies (Hokkaido, Kansai, Shikoku, Kyushu and Japan Atomic Power), Mitsubishi Heavy Industries, and Westinghouse, with a view to providing a nuclear power source to meet future energy demand in Japan. The APWR was developed based on the results of the Improvement and Standardization Program, promoted by the Ministry of International Trade and Industry, with reconsideration of the needs of age, such as construction cost reduction, enhanced safety and increased reliability. One of the important concepts of the APWR is its large power rating that decreases the construction cost per unit of electric generation capacity. Though the electric output was lower at the early stage of basic design than it is now, uprating to approximately 1530 MW is achieved based on the results of design progress and high efficiency improvements to the steam turbine and reactor coolant pumps. Furthermore, the APWR remarkably enhances reliability, safety operability and maintainability by introducing new technologies that include a radial reflector and advanced accumulators. The first APWR is planned to be built at Tsuruga No. 3 and No. 4 by the Japan Atomic Power Company and will be the largest commercial operation plant in the early 21st century. (author)

  13. Fallen star legends and traditional religion of Japan: an aspect of star lore

    2015-08-01

    Japanese star lore is a complex mixture of animism, Buddhism, Shinto-ism, Confucianism and folk beliefs. Although some studies have been done on rituals concerning constellation developed in esoteric Buddhism (e.g. Journal Culture and Cosmos, Vol. 10 no 1 and 2), studies on other aspects of Japanese star lore are limited, in particular, to the English audience.In historic literatures, there often mentioned abnormal astronomical phenomena, such as, eclipse, meteors and comets. In this paper, I will discuss the possibility of reference to these astronomical phenomena in order to talk about some historical facts.In western part of Japan, there are Shinto shrines and Buddhistic temples that are said to be built as monuments of fallen stars. Usually fallen stars were divided into three, and a trio of shrines/temples are said to be the remnants of this phenomenon. Similar legends are found in Kudamatsu (that means "fallen pine=pine where stars fallen") of Yamaguchi Prefecture, Bisei-cho (that means "beautiful star") of Okayama Prefecture, Hoshida (that means "rice field or village of star") shrine of Osaka, and also Hoshida shrine of Nagoya.The purpose of this presentation is not to argue whether fallen star legend was truly astronomical phenomenon, such as, meteor or not. Instead, I will discuss why similar legends have been talked concerning the origin of particular shrines or temples. Citing Eliade who related gorge and alchemy producing spark to astronomical phenomena, I will disclose the possibility to relate these astronomical legends to the coming of the naturalized Japanese from Korean Peninsula who introducd forge to Japan abound 5 to 6 centuries.

Currently various irradiated products available in our daily life including irradiated potatoes and spices were displayed together with explanatory panels and attractions. The number of participants has increased every year and constantly exceeded 20,000 in recent years. This activity has become a good medium for the consumer to recognize the quality of the irradiated potatoes which has been distributed in the market since 1974, and irradiated spices, the next candidate for the clearance under examination by Japanese government. Taking advantage of this opportunity, we have demonstrated toward the participants that irradiation-decontaminated spices are superior to conventional heat-treated ones in aromatic quality as well as conducting survey of the visitor's feeling on radiation and irradiated foods. These activities would be potentially effective to facilitate public acceptance of irradiation decontamination of spices.

    The increase in implant patients is expected to give rise to a new problem: the changing general health status of those who have had implants placed. The aim of this present study was to find out the needs of and proper measures for elderly implant patients in long-term care facilities. A questionnaire was sent by mail to 1,591 long-term care health facilities, daycare services for people with dementia, and private nursing homes for the elderly in the Osaka area, which is in the middle area of Japan, in order to extract patients with cerebrovascular disease or dementia who were possibly at risk of inadequate oral self-care, as well as patients with implants. Approximately half of all facilities responded that they cannot recognize implants, and many facilities did not know anything about oral care for implant patients. Residents with implants were reported at 19% of all facilities. Also, the facilities pointed out problems with implants relating to the difference in oral care between implants and natural teeth. There are people with implants in some 20% of caregiving facilities, and there is a low level of understanding regarding implants and their care among nurses and care providers who are providing daily oral care. © 2013 Wiley Periodicals, Inc.

    This is the progress report of the research activities in the Laboratory of Nuclear Studies during the period from April, 1980, to March, 1981. The activities were carried out by the OULNS staffs and also by outsiders at the OULNS. In this period, the X-ray astrophysics group, the radiation physics group and the high energy physics group joined the OULNS. The main accelerators in the OULNS are a 110 cm variable energy cyclotron and a 4.7 MeV Van de Graaff machine. The detailed experimental studies on inbeam e-gamma spectroscopy and beta-decay were carried out at two accelerator laboratories. The radiochemistry facility and a mass spectrometer were fully used. The research activities extended to high energy physics by utilizing national facilities, such as a 230 cm cyclotron in the Research Center for Nuclear Physics and a proton synchrotron in the National Laboratory for High Energy Physics. The theoretical studies on elementary particles and nuclear physics were carried out also. It is important that the facilities in the OULNS were used by the outsiders in Osaka University, such as solid state physics group and particle-induced X-ray group. The activities of the divisions of cyclotron, Van de Graaff, high energy physics, accelerator development and nuclear instrumentation, mass spectroscopy, radioisotope, solid state and theoretical physics are reported.

    The 16th International Conference on Positron Annihilation (ICPA-16) was held at the University of Bristol, United Kingdom during 19-24 August, 2012. This triennial conference is the foremost gathering of the Positron Annihilation Physics community and it was hosted in the UK for the first time since the series of meetings first started back in 1965. The University of Bristol, the Alma Mater of Paul Dirac, is situated at the heart of the city, and it has established a worldwide reputation in research and teaching. Many of the topics which were discussed during ICPA-16 form an integral part of the research themes in the schools of Physics, Chemistry and Engineering of this University. ICPA-16 attracted a diverse audience, both from academic and industrial institutions, with over 200 participants from 29 countries. It continued the long held tradition of showcasing novel research in the field of positron annihilation and a total of 170 papers were presented as talks and posters. The papers reported studies of metallic and semi-conducting solids, polymers and soft matter, porous materials, surfaces and interfaces, as well as advances in experimental, analytical and biomedical applications. The high quality of the presented work, coupled with the enthusiastic exchange of ideas, provided an invaluable forum, especially for younger researchers and postgraduate students. The excellence of student presentations was acknowledged by the award of prizes for the best student posters, which were received by David Billington (University of Bristol, UK), Moussa Sidibe (CEMHTI, France) and Hongxia Xu (Tohoku University, Japan). All papers published in the Conference Proceedings were reviewed by ICPA-16 participants. We are indebted to all reviewers who contributed their time and intellectual resources, allowing the refereeing and editing process to move smoothly toward the compilation of the Proceedings.

    Serious shortage is predicted on cokes for blast furnaces in the first half of the 21st century. In order to deal flexibly with the fluid world market in the future, it is necessary to have a technology developed, by which coals from coking coal to non-coking dust coal can be used. The Japan Iron and Steel Federation and the Center for Coal Utilization, Japan are working on research and development of a new process with enhanced environmentality and economy (SCOPE 21) as a coke manufacturing process to respond to the requirements arisen from the above situation. The process is assessed basing on basic technological seeds such as rapid coal heating and high-speed carbonization and reformation of middle to low temperature cokes. The organizations are moving forward an eight-year development program which has started in fiscal 1994. This paper reports the summary of the development, and results of investigations and researches performed during fiscals 1994 and 1995. Rapid heating tests, middle to low temperature coke reformation tests, and tests for plug transportation of high-temperature coal have been performed. It has been verified, for example, that rapid coal heating can improve coke strength. The development work is being promoted toward grain size distribution and upscaling problems. 5 refs., 16 figs., 2 tabs.

    Humankind will go into the 21st century in five years. People tend to talk about the end of this century and don't talk much about what will happen on the earth and in the field of energy in the 21st century because the economic, politics and social affairs in the future after 2000 are uncertain and cloudy in the world and in Japan. Japan is facing serious difficulties of economic deflation which might continue at least for more five years. She is also facing political and social turmoil such as a strong distrust in the political issues particularly in the behaviors of political people and Aum crazy murders. However I would like to adventure to make the clear outlook up to 2010 of energy problems in the world and Japan. People will face the serious unsuitability in the energy supply security in the world, in the Asian countries and in Japan. (author)

    Fifty-four cases of glucose 6-phosphate dehydrogenase (G6PD) deficiency have so far been reported in Japan. Among them, 21 G6PD variants have been characterized. Nineteen out of the 21 variants were characterized in our laboratory and G6PD Heian and "Kyoto" by others. G6PD Tokyo, Tokushima, Ogikubo, Kurume, Fukushima, Yokohama, Yamaguchi, Wakayama, Akita, Heian and "Kyoto" were classified as Class 1, because all these cases showed chronic hemolytic anemia and severe enzyme deficiency. All these variants showed thermal instability. G6PD Mediterranean-like, Ogori, Gifu and Fukuoka were classified as Class 2, whereas G6PD Hofu, B(-) Chinese, Ube, Konan, Kamiube and Kiwa belonged to Class 3. All the 6 Class 3 variants were found as the results of the screening tests. The incidence of the deficiency in Japanese seems to be 0.1-0.5% but that of the cases which may slow drug-induced hemolysis would be much less. G6PD Ube and Konan appear to be relatively common in Japan.

  10. Interaction of the SPG21 protein ACP33/maspardin with the aldehyde dehydrogenase ALDH16A1

    Mast syndrome (SPG21) is an autosomal-recessive complicated form of hereditary spastic paraplegia characterized by dementia, thin corpus callosum, white matter abnormalities, and cerebellar and extrapyramidal signs in addition to spastic paraparesis. A nucleotide insertion resulting in premature truncation of the SPG21 gene product acidic cluster protein 33 (ACP33)/maspardin underlies this disorder, likely causing loss of protein function. However, little is known about the function of maspardin. Here, we report that maspardin localizes prominently to cytoplasm as well as to membranes, possibly at trans-Golgi network/late endosomal compartments. Immunoprecipitation of maspardin with identification of coprecipitating proteins by mass spectrometry revealed the aldehyde dehydrogenase ALDH16A1 as an interacting protein. This interaction was confirmed using overexpressed proteins as well as by fusion protein pull down experiments, and these proteins colocalized in cells. Further studies of the function of ALDH16A1 and the role of the maspardin–ALDH16A1 interaction in neuronal cells may clarify the cellular pathogenesis of Mast syndrome. PMID:19184135

    Although Japan is a non-endemic area with nasopharyngeal carcinoma (NPC), the proportion of WHO type I NPC in Japan are different from that in non-endemic areas such as North America and Europe. Recently, it is said that not only Epstein-Barr virus (EBV) but also human papillomavirus (HPV) has an influence on NPC in non-endemic areas. The aim of this study is to clarify the influence of HPV on NPC in Japan. Paraffin-embedded tumor specimens were available for 59 patients with NPC diagnosed between 1996 and 2015. We detected the virus status by p16 immunohistochemistry, HPV PCR, and in situ hybridization for Epstein-Barr virus (EBV)-encoded RNA. Kaplan-Meier curves were used to compare the overall survival by viral status. Among the 59 patients, 49 (83%) were EBV-positive/HPV-negative, 2 (3%) were EBV-positive/HPV-positive, and 8 (16%) were EBV-negative/HPV-negative. All HPV-positive NPCs were co-infected with EBV. There were no significant differences between the overall survival in the three groups (p=0.111). In Japan, HPV was detected in a few patients with NPC, and we suggest that HPV has no influence on NPC carcinogenesis in this population. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Objectives Chromosome 9p21 single nucleotide polymorphism (SNP) is a susceptibility variant for acute myocardial infarction (AMI) in the primary prevention setting. However, it is controversial whether this SNP is also associated with recurrent myocardial infarction (ReMI) in the secondary prevention setting. The purpose of this study is to evaluate the impact of chromosome 9p21 SNP on ReMI in patients receiving secondary prevention programmes after AMI. Design A prospective observational study. Setting Osaka Acute Coronary Insufficiency Study (OACIS) in Japan. Participants 2022 patients from the OACIS database. Interventions Genotyping of the 9p21 rs1333049 variant. Primary outcome measures ReMI event after survival discharge for 1 year. Results A total of 43 ReMI occurred during the 1 year follow-up period. Although the rs1333049 C allele had an increased susceptibility to their first AMI in an additive model when compared with 1373 healthy controls (OR 1.20, 95% CI 1.09 to 1.33, p=2.3*10−4), patients with the CC genotype had a lower incidence of ReMI at 1 year after discharge of AMI (log-rank p=0.005). The adjusted HR of the CC genotype as compared with the CG/GG genotypes was 0.20 (0.06 to 0.65, p=0.007). Subgroup analysis demonstrated that the association between the rs1333049 CC genotype and a lower incidence of 1 year ReMI was common to all subgroups. Conclusions Homozygous carriers of the rs1333049 C allele on chromosome 9p21 showed a reduced risk of 1 year ReMI in the contemporary percutaneous coronary intervention era, although the C allele had conferred susceptibility to their first AMI.

    In order to clarify the real conditions of occupational health services (OHS) in small-scale enterprises (SSEs) in Japan, we analyzed questionnaires recovered from 765 SSEs in the area of a city neighboring Osaka City (recovery rate, 69.3%). The SSEs included 358 SSEs with 1 to 4 workers (46.8% of total SSEs), 203 with 5 to 9 (26.5%), 163 with 10 to 29 (21.3%) and 41 with 30 to 49 (5.4%). The main types of businesses were manufacturing (374, 48.9% of total SSEs), wholesale/retail trade/restaurants (153, 20.0%), community, social and personal services (132, 17.3%) and construction (72, 9.4%). Health examinations were performed in 47.7% of SSEs. The reason for the lack of examinations were "shortage of time" (33.3% of SSEs lacking health examination) and "employees do not want to be examined" (28.1%). Some health promotion measures were conducted in 29.2% of SSEs. Health examination (59.0% of SSEs), health promotion (36.5%), measure of mental health (25.9%) and information service for employers and employees (25.5%) were demanded by SSEs as OHS. Financial subsidies and economical incentives were demanded by 46.4% and 28.8% of SSEs, respectively. Regional occupational health center in this area was poorly known among SSEs (8.2%), but health examination (48.4%), information service (37.5%), assessment of work method and advice to improve (19.8%) and environment measurement (12.4%) are demanded of the center by SSEs.

    Mouse trisomy 16 has been proposed as an animal model of Down syndrome (DS), since this chromosome contains homologues of several loci from the q22 band of human chromosome 21. The recent mapping of the defect causing familial Alzheimer disease (FAD) and the locus encoding the Alzheimer amyloid {beta} precursor protein (APP) to human chromosome 21 has prompted a more detailed examination of the extent of conservation of this linkage group between the two species. Using anonymous DNA probes and cloned genes from human chromosome 21 in a combination of recombinant inbred and interspecific mouse backcross analyses, the authors have established that the linkage group shared by mouse chromosome 16 includes not only the critical DS region of human chromosome 21 but also the APP gene and FAD-linked markers. Extending from the anonymous DNA locus D21S52 to ETS2, the linkage map of six loci spans 39% recombination in man but only 6.4% recombination in the mouse. A break in synteny occurs distal to ETS2, with the homologue of the human marker D21S56 mapping to mouse chromosome 17. Conservation of the linkage relationships of markers in the FAD region suggests that the murine homologue of the FAD locus probably maps to chromosome 16 and that detailed comparison of the corresponding region in both species could facilitate identification of the primary defect in this disorder. The break in synteny between the terminal portion of human chromosome 21 and mouse chromosome 16 indicates, however, that mouse trisomy 16 may not represent a complete model of DS.

    A free-electron laser with a 38-MeV L-band linear accelerator was developed at the Institute of Scientific and Industrial Research, Osaka University. The self-amplified spontaneous emission was observed at wavelengths of 20 and 40 {mu}m with a high-intensity single-bunch beam passing through a wiggler. In the oscillation experiments with a multibunch beam laser light was obtained at wavelengths from 32 to 40 {mu}m. The peak power in a micropulse of the laser is estimated to be 8.3 MW at a wavelength of 40 {mu}m. In order to apply the laser to basic researches some components of the linac and the optical cavity are being improved. (author)

    Large earthquakes have been associated with cardiovascular disease (CVD) mortality. In Japan, the 1995 Great Hanshin-Awaji (H-A) Earthquake was an urban-underground-type earthquake, whereas the 2011 Great East Japan (GEJ) Earthquake was an ocean-trench type. In the present study, we examined how these different earthquake types affected CVD mortality. We examined death certificate data from 2008 to 2012 for 131 municipalities in Iwate, Miyagi, and Fukushima prefectures (n=320,348) and from 1992 to 1996 for 220 municipalities in Hyogo, Osaka, and Kyoto prefectures (n=592,670). A Poisson regression model showed significant increases in the monthly numbers of acute myocardial infarction (AMI)-related deaths (incident rate ratio [IRR] GEJ=1.34, P=0.001; IRR of H-A=1.57, Pdeaths (IRR of GEJ=1.42, Pdeaths remained significant only for H-A (IRR=1.13, P=0.029). When analyzing the standardized mortality ratio (SMR) after the earthquakes using the Cochran-Armitage trend test, seismic intensity was significantly associated with AMI mortality for 2 weeks after both the GEJ (P for trend=0.089) and H-A earthquakes (P for trend=0.005). Following the GEJ and H-A earthquakes, there was a sharp increase in CVD mortality. The effect of the disaster was sustained for months after the H-A earthquake, but was diminished after the GEJ Earthquake.

    The Rn-222 concentration in underground water is reported as follows, which is the result obtained when the ground inspection was carried out in the Research Reactor Institute of Kyoto University located at Kumatori area in Osaka stratum group. Underground water, at different depth, well water and rain water were taken, and the contained Rn-222 was extracted with toluene to measure by liquid scintillation technique. Rn-222 concentration in rain water was 3.5 - 8.0 pCi/l, while the concentration in well water was 130 - 250 pCi/l, and that in underground water was 240 - 313 pCi/l. The seasonal change, geographical difference and variation according to depth of Rn-222 concentration were examined. Rn-222 behavior in soil should be investigated more in detail in reference to Rn-222 dispersion, transport and equilibrium problems in soil-water system in the future. (Kobatake, H.)

  6. Climate Change Taxes and Energy Efficiency in Japan

    International Nuclear Information System (INIS)

    Kasahara, S.; Paltsev, S.; Reilly, J.; Jacoby, H.; Ellerman, A.D.

    2007-01-01

    In 2003 Japan proposed a Climate Change Tax to reduce its CO2 emissions to the level required by the Kyoto Protocol. If implemented, the tax would be levied on fossil fuel use and the revenue distributed to encourage the purchase of energy efficient equipment. Analysis using the MIT Emissions Prediction and Policy Analysis (EPPA) model shows that this policy is unlikely to bring Japan into compliance with its Kyoto target unless the subsidy encourages improvement in energy intensity well beyond Japan's recent historical experience. Similar demand-management programs in the US, where there has been extensive experience, have not been nearly as effective as they would need to be to achieve energy efficiency goals of the proposal. The Tax proposal also calls for limits on international emission trading. We find that this limit substantially affects costs of compliance. The welfare loss with full emissions trading is 1/6 that when Japan meets its target though domestic actions only, the carbon price is lower, and there is a smaller loss of energy-intensive exports. Japan can achieve substantial savings from emissions trading even under cases where, for example, the full amount of the Russian allowance is not available in international markets

    For the purpose of public education of radiation and radiation-related technology towards school kids and their parents through efficient information transfer, 'RADIATION FAIR - the relationship between daily life and radiation' has been successfully held at Kintetsu Department Store, one of the major departmental stores in downtown Osaka, the second largest city in Japan during summer vacation in every August for 19 years. Currently various irradiated products available in our daily life including irradiated potatoes and spices were displayed together with explanatory panels and attractions. The number of participants has increased every year and constantly exceeded 20,000 in recent years. This activity has become a good medium for the consumer to recognize the quality of the irradiated potatoes which has been distributed in the market since 1974, and irradiated spices, the next candidate for the clearance under examination by Japanese government. Taking advantage of this opportunity, we have demonstrated toward the participants that irradiation-decontaminated spices are superior to conventional heat-treated ones in aromatic quality as well as conducting survey of the visitor's feeling on radiation and irradiated foods. These activities would be potentially effective to facilitate public acceptance of irradiation decontamination of spices.

    1989-01-01

    Data on the development level of nuclear power in Japan as of 1988 beginning are presented. Total registed electric power of 36 nuclear power units under operation constituted 28046 MW. 13 power units with 12268 MW total power are under construction. In 1987 188.4 TWH electric power was generated at the Japanese NPPs, it constituted 31.7% of total electric power generation. About 360 bil. yens were assigned from the state budget to further development of nuclear power engineering. Efforts to create the improved BWR type reactor, as well as, scientific and research efforts on the development of fast breeder reactors, improvement of uranium enrichment and radioactive waste storage are carried out. It is expected that share of nuclear power in electric power generation in Japan will reach 40% to the beginning of the 21-th century

It is associated with bacterial urinary tract infections caused by indigo-producing and indirubin-producing bacteria, usually affects women, and is associated with alkaline urine, constipation, and a high bacterial load in the urine. Almost all patients with purple urine bag syndrome are catheterized due to significant disability, and the urinary pH is 7.0 or more. In general, intensive treatment with antibiotics is not recommended. Purple urine bag syndrome per se almost always appears to be asymptomatic and harmless. However, caution is needed, because some cases have been reported to show progression to severe disease states, so further research into the morbidity and mortality of this infection is warranted.Keywords: purple urine, urinary catheterization, geriatrics, urinary tract infection

    Human papillomavirus type 16 (HPV-16) is the major risk factor for development of cervical cancer. The major oncoprotein E7 enhances cell growth control. However, E7 has in some reports been shown to induce apoptosis suggesting that there is a delicate balance between cell proliferation and induction of cell death. We have used the osteosarcoma cell line U2OS cells provided with E7 and the cdk2 inhibitor p21 (cip1/waf1) under inducible control, as a model system for the analysis of E7-mediated apoptosis. Our data shows that simultaneous expression of E7 and p21 proteins induces cell death, possibly because of conflicting growth control. Interestingly, E7/p21-induced cell death is associated with the activation of a newly identified mediator of apoptosis, namely cathepsin B. Activation of the cellular caspases is undetectable in cells undergoing E7/p21-induced apoptosis. To our knowledge, this is the first time a role for cathepsin B is reported in HPV-induced apoptotic signalling

    2004-01-01

    The forum was opened at Tsuruga City in Japan from 26 to 27 in April, 2004. It initially discussed Japan's energy policy with the central focus based on the fundamental law of energy, presenting energy policies of each country and the position and future prospects of nuclear energy from these policies. Considering that the forum took place in Tsuruga City (where the FBR 'Monju' is located), expectations on 'Monju' and demands for its international utilization was discussed by researches from abroad, universities in Japan, and the possibility of its realization with views on firm implementation measures was exchanged. Keynote speech was 'Energy policy in the 21st century', special presentation 'importance of science and technology development and cultivation of improvement'. The forum consisted of three sessions: the session I 'energy policy and the role of each country in the 21st century', session II 'international utilization of Monju for FR development' and III 'regional technology development by utilizing nuclear related technology and facilities in Fukui pref.'. There were three panel discussions. 24 members composed speaker and panelists from USA, Turkey, France, UK, China, Switzerland, Korea, Russia and Japan. (S.Y.)

    The Purpose of this study was to evaluate retrospectively the management and prognosis of Merkel cell carcinoma of the eyelid in Japanese patients. Cases diagnosed as Merkel cell carcinoma of the eyelid from January 1993 to February 2005 in 111 institutions in Japan were included in this retrospective study. Management and prognosis were evaluated. The total number of cases enrolled was 21 (5 male and 16 female patients). Excision of the tumor was carried out in 18 cases. Two cases were treated with either irradiation or local injection of interferon after biopsy of the tumor. After initial treatment, there were recurrences in 3 cases; local recurrence in one case and nodal metastasis in two cases. No patient died because of Merkel cell carcinoma of the eyelid. Excision with wide surgical margins with irradiation is recommended as the first choice of treatment for Merkel cell carcinoma of the eyelid. Because the number of patients was only 21 and the duration of observation was short, further investigation is necessary to determine the optimal management and more accurate prognosis for Merkel cell carcinoma.

    In August 2009, after 54 years of virtually unbroken rule, Japan's Liberal Democratic Party (LDP) was ousted from power by the Democratic Party of Japan (DPJ). The DPJ's campaign platform included a pledge to facilitate extreme reductions in greenhouse gas (GHG) emissions. Yet, at the COP16 meeting in Cancun, Japan announced that it would not accept further emission reduction targets without broader commitment from all nations. This paper seeks to explain this dichotomy by employing a targeted stakeholder evaluation based on surveys with 321 Japanese citizens to assess the extent to which influential stakeholder groups in Japan supports a potentially costly transition to a low-carbon energy infrastructure amidst severe economic challenges that the nation faces. Findings help explain Japan's adversarial role in COP16 negotiations in Cancun, despite the stated GHG reduction ambitions of Japan's current ruling party. The analysis concludes that if the DPJ does embrace aggressive CO{sub 2} reduction targets in the future, the strategic focus will likely mirror the former ruling party's energy policy of bolstering nuclear power generation capacity and promoting energy efficiency improvements while exhibiting lukewarm commitment to supporting capacity development in alternative sources of energy supply such as solar panels and wind turbines. - Research highlights: {yields} Public consensus exists regarding which energy policy goals are important in Japan. {yields} Minor perceptual differences are not of a catalytic nature. {yields} Public consensus does not deviate significantly from past LDP energy policy. {yields} Unlikely that the DPJ will pursue costly energy transition initiatives. {yields} Likely that the DPJ energy strategy will be substantively similar to LDP strategy. {yields} Any differences in strategy will focus on CO{sub 2} reduction magnitude not substance.

    2016-10-14

    Two geographically distant M. tuberculosis sublineages, Tur from Turkey and T3-Osaka from Japan, exhibit partially identical genotypic signatures (identical 12-loci MIRU-VNTR profiles, distinct spoligotyping patterns). We investigated T3-Osaka and Tur sublineages characteristics and potential genetic relatedness, first using MIRU-VNTR locus analysis on 21 and 25 samples of each sublineage respectively, and second comparing Whole Genome Sequences of 8 new samples to public data from 45 samples uncovering human tuberculosis diversity. We then tried to date their Most Recent Common Ancestor (MRCA) using three calibrations of SNP accumulation rate (long-term = 0.03 SNP/genome/year, derived from a tuberculosis ancestor of around 70,000 years old; intermediate = 0.2 SNP/genome/year derived from a Peruvian mummy; short-term = 0.5 SNP/genome/year). To disentangle between these scenarios, we confronted the corresponding divergence times with major human history events and knowledge on human genetic divergence. We identified relatively high intrasublineage diversity for both T3-Osaka and Tur. We definitively proved their monophyly; the corresponding super-sublineage (referred to as “T3-Osa-Tur”) shares a common ancestor with T3-Ethiopia and Ural sublineages but is only remotely related to other Euro-American sublineages such as X, LAM, Haarlem and S. The evolutionary scenario based on long-term evolution rate being valid until T3-Osa-Tur MRCA was not supported by Japanese fossil data. The evolutionary scenario relying on short-term evolution rate since T3-Osa-Tur MRCA was contradicted by human history and potential traces of past epidemics. T3-Osaka and Tur sublineages were found likely to have diverged between 800 y and 2000 years ago, potentially at the time of Mongol Empire. Altogether, this study definitively proves a strong genetic link between Turkish and Japanese tuberculosis. It provides a first hypothesis for calibrating TB Euro-American lineage molecular clock

    miRNAs are small regulatory RNA molecules involved in posttranscriptional gene silencing. Their biosynthesis results in the formation of duplex consisting of a leading and a passenger strand of mature miRNA. The leading strand exhibits the main activity but recent findings indicate a certain role of the passenger strand as well. Deregulated levels of miRNA were found in many types of cancers including colorectal cancer. miR-21 and miR-16 were indicated as possible markers of colorectal cancer, however, small attention to gender differences in their expression was paid so far. Therefore, the aim of our study was to investigate the expression of miR-21-5p, miR-21-3p, miR-16-5p and miR-16-3p in human colorectal cancer tissue and compare it to the adjacent tissues taken during surgery in men and women separately. Our results showed an up-regulation of all measured miRNAs in tumor tissue compared to adjacent tissues. As expected, tumors and adjacent tissues exhibited a significantly higher expression of leading miRNAs compared to passenger strand of miR-21 and miR-16. The expression of leading and passenger strand of miR-21 and miR-16 positively correlated exhibiting the highest correlation coefficient in the distal tissue. The expression pattern showed gender-dependent differences, with higher levels of miRNA in men than in women. Our findings indicate a gender-related expression pattern of miRNA, which should be considered as an important factor in generating new prognostic or diagnostic biomarkers.

  1. Characteristics of primary sclerosing cholangitis in Japan.

    2007-10-01

    At a workshop on primary sclerosing cholangitis (PSC) held during Digestive Disease Week - Japan 2003, 388 PSC cases in Japan were analyzed. Two peaks in the age distribution were also observed in this survey. Jaundice and itching, major symptoms in PSC patients included in the diagnostic criteria, were observed in only 28% and 16%, respectively. Alkaline phosphatase levels were less than twofold of the upper limit of the normal range in 35%. In this regard, the diagnostic criteria in 2003 from the Mayo Clinic, including cholestatic symptoms and two- to threefold increases in serum alkaline phosphatase, should be modified in Japan. Inflammatory bowel diseases were complicated in 37%, and autoimmune pancreatitis (AIP) in 7.2%. PSC cases with inflammatory bowel diseases were younger than the average, creating the firstpeak in age distribution, and have similar characteristics compared to patients with PSC in foreign countries. In addition, even after the exclusion of cases of sclerosing cholangitis complicated with AIP, the second peak in the age distribution was clearly evident. Recently, a concept of immunoglobulin G4-related sclerosing cholangitis has been postulated, which has a similar pathogenesis to AIP but without apparent pancreatic lesions. PSC patients without apparent involvement of the pancreas may be present in older patients and seem to be specific to Japan.

    Microtremor observations have been carried out with an objective to estimate underground structures including the foundation depth in the Osaka-Kobe area which has been greatly damaged by the Hyogoken-nanbu earthquake in 1995. Different organizations have made seismic surveys and boring investigations in this area, by which elucidation has been made on the underground structures. The present observations are intended to identify S-wave velocity distribution in a wide area from the ground surface to the foundation, which is difficult to be verified by using conventional surveys and investigations. Methods to detect surface waves which are contained in microtremors include the frequency-wave number method (the F-K method) and the spatial autocorrelation method (the SPAC method). The SPAC method can estimate phase velocities of longer waves for the size of an array than with the F-K method, and is more advantageous in estimating ground structures at greater depths. S-wave velocity structure was estimated down to the foundation rocks existing in depths of about 0.5 to 2.0 km. For estimating the phase velocities in Raleigh waves, the SPAC method and the expanded spatial autocorrelation method were used. The underground structures thus derived showed a good agreement with the results of explorations using other methods. 8 figs., 1 tab.

    Full Text Available Koichi Sugimoto, Shogo Adomi, Hiroyuki Koike, Atsunobu Esa Department of Urology, NTT West Osaka Hospital, Osaka, Japan Background: Procalcitonin has been advocated as a marker of bacterial infection, so this study was carried out to determine the usefulness of serum procalcitonin in the early diagnosis of urosepsis. Methods: The subjects were 37 febrile patients with urinary tract infection in whom we examined the serum procalcitonin concentration at the start of treatment. Results: Thirty patients had acute pyelonephritis (16 simple, 14 complex, one had emphysematous pyelonephritis, five had acute prostatitis, and one had acute epididymitis. The procalcitonin level was <0.5 ng/mL in 18 patients, ≥0.5 ng/mL in one patient, ≥2 ng/mL in seven patients, and ≥10 ng/mL in 11 patients. Five of the 11 patients with procalcitonin levels ≥ 10 ng/mL had disseminated intravascular coagulation. All patients with urinary tract obstruction and disseminated intravascular coagulation had procalcitonin levels ≥ 10 ng/mL. Conclusion: Although this retrospective study comprised a small number of patients, we found that procalcitonin was a useful marker for urinary tract infection.

    1992-01-01

    Japan imported over 110 million tons of coal in fiscal year 1991 ending 31 March 1992. The recent demand prospect assumes that coal imports will amount up to 150 million tons at the end of the century despite the long-term energy forecast (May 1990). Stable and reasonable imports of coal will be very important for the national economy because Japan can not rely on domestic coal which will inevitably be decreasing from a production level of only about eight million tons in 1991. Regarding environmental standards, Japan has enacted the world's most severe regulations to eliminate emissions of SOx, NOx, etc. However, the restriction of emissions of carbon dioxide remains an important subject with regard to global greenhouse issues. Japan has been proposing a so-called open-quotes New Earth 21 Programclose quotes which emphasizes the importance of clean uses of coal with a view to keeping pace with the requirements of rapidly developing ASEAN and other countries. Coal water mixture (CWM) produced in China began to be regularly exported to Japan in March 1992. On the other hand, a large-scale CWM production and combustion project of 500,000 tons/year was launched last fall in the Onahama/Nakoso area, about 200 km north of Tokyo. It is expected to begin commercial operation in June 1993

This workshop was supported by RIKEN (The Institute of Physical and Chemical Research) and by Yukawa Institute. The scientific program was focused on the upcoming polarized collider RHIC. The workshop was also an annual meeting of RHIC Spin Collaboration (RSC). The number of participants was 55, including 28 foreign visitors and 8 foreign-resident Japanese participants, reflecting the international nature of the RHIC spin program. At the workshop there were 25 oral presentations in four sessions, (1) RHIC Spin Commissioning, (2) Polarized Partons, Present and Future, (3) New Ideas on Polarization Phenomena, (4) Strategy for the Coming Spin Running. In (1) the successful polarized proton commissioning and the readiness of the accelerator for the physics program impressed us. In (2) and (3) active discussions were made on the new structure function to be firstly measured at RHIC, and several new theoretical ideas were presented. In session (4) we have established a plan for the beam time requirement toward the first collision of polarized protons. These proceedings include the transparencies presented at the workshop. The discussion on ''Strategy for the Coming Spin Running'' was summarized by the chairman of the session, S. Vigdor and G. Bunce.

    Hiroshi Asakura

    Full Text Available Campylobacter jejuni is a leading cause of human gastroenteritis worldwide. This study aimed at a better understanding of the genetic diversity of this pathogen disseminated in Japan. We performed multilocus sequence typing (MLST of Campylobacter jejuni isolated from different sources (100 human, 61 poultry, and 51 cattle isolates in Japan between 2005 and 2006. This approach identified 62 sequence types (STs and 19 clonal complexes (CCs, including 11 novel STs. These 62 STs were phylogenetically divided into 6 clusters, partially exhibiting host association. We identified a novel ST (ST-4526 that has never been reported in other countries; a phylogenetic analysis showed that ST-4526 and related STs showed distant lineage from the founder ST, ST-21 within CC-21. Comparative genome analysis was performed to investigate which properties could be responsible for the successful dissemination of ST-4526 in Japan. Results revealed that three representative ST-4526 isolates contained a putative island comprising the region from Cj0737 to Cj0744, which differed between the ST-4526 isolates and the reference strain NCTC11168 (ST-43/CC-21. Amino acid sequence alignment analyses showed that two of three ST-4526 isolates expressed 693aa- filamentous hemagglutination domain protein (FHA, while most of other C. jejuni strains whose genome were sequenced exhibited its truncation. Correspondingly, host cell binding of FHA-positive C. jejuni was greater than that of FHA-truncated strains, and exogenous administration of rFHA protein reduced cell adhesion of FHA-positive bacteria. Biochemical assays showed that this putative protein exhibited a dose-dependent binding affinity to heparan sulfate, indicating its adhesin activity. Moreover, ST-4526 showed increased antibiotic-resistance (nalidixic acid and fluoroquinolones and a reduced ability for DNA uptake. Taken together, our data suggested that these combined features contributed to the clonal thriving of ST

  13. Competition in Japan

    OpenAIRE

    Michael E. Porter; Mariko Sakakibara

    2004-01-01

    This article examines competition in Japan and its link to postwar economic prosperity. While Japan's industrial structure and competition policy seem to indicate that competition in Japan has been less intense, the empirical evidence does not support this conclusion. The sectors in which competition was restricted prove to be those where Japan was not internationally successful. In the internationally successful sectors, internal competition in Japan was invariably fierce. While the level of...

    Cervical, endometrial, and ovarian cancers, have both high morbidity and mortality among the gynecologic malignant tumors in Japan. The present study was conducted using both the population-based cancer registry and the gynecologic cancer registry to elucidate the characteristics of gynecologic malignant tumors in Japan. Based on nationwide estimates from the population-based cancer registry in Japan, the morbidities and mortality of cervical, endometrial, and ovarian cancers were obtained and used for analysis. Clinicopathologic factors for cervical cancer, endometrial cancer, ovarian cancer, including age, clinical stage, postsurgical stage, histological type, therapeutic strategy, and prognosis were retrieved from the gynecologic cancer registry published by the Japan Society of Obstetrics and Gynecology and used for analysis. The morbidities of cervical, endometrial, and ovarian cancers were 10,908, 13,606, and 9,384 women in 2012, respectively. The prevalence of endometrial cancer has significantly and consistently been increasing and represents the most common gynecologic malignant tumor in Japan. The mortalities of cervical, endometrial, and ovarian cancers were 2.1, 1.3, and 3.2 per 100,000 in 2012, respectively. In 2014, 52.2% of cervical cancer patients were classified as stage I, 22.5% as stage II, 10.2% as stage III, and 11.2% as stage IV. In addition, 71.9% of endometrial cancer patients were classified as stage I, 6.0% as stage II, 13.3% as stage III, and 7.5% as stage IV. Finally, 43.2% of ovarian cancer patients were classified as stage I, 9.1% as stage II, 27.6% as stage III, and 7.2% as stage IV. Twelve-point six percent of ovarian cancer patients received neoadjuvant chemotherapy. PMID:28198168

    Lynch syndrome is an autosomal dominant condition caused by pathogenic mutations in the DNA mismatch repair (MMR) genes. Although commonly associated with clinical features such as intellectual disability and congenital anomalies, contiguous gene deletions may also result in cancer predisposition syndromes. We report on a 52-year-old male with Lynch syndrome caused by deletion of chromosome 2p16.3-p21. The patient had intellectual disability and presented with a prostatic adenocarcinoma with an incidentally identified synchronous sigmoid adenocarcinoma that exhibited deficient MMR with an absence of MSH2 and MSH6 protein expression. Family history was unrevealing. Physical exam revealed short stature, brachycephaly with a narrow forehead and short philtrum, brachydactyly of the hands, palmar transverse crease, broad and small feet with hyperpigmentation of the soles. The patient underwent total colectomy with ileorectal anastomosis for a pT3N1 sigmoid adenocarcinoma. Germline genetic testing of the MSH2, MSH6, and EPCAM genes revealed full gene deletions. SNP-array based DNA copy number analysis identified a deletion of 4.8 Mb at 2p16.3-p21. In addition to the three Lynch syndrome associated genes, the deleted chromosomal section encompassed genes including NRXN1, CRIPT, CALM2, FBXO11, LHCGR, MCFD2, TTC7A, EPAS1, PRKCE, and 15 others. Contiguous gene deletions have been described in other inherited cancer predisposition syndromes, such as Familial Adenomatous Polyposis. Our report and review of the literature suggests that contiguous gene deletion within the 2p16-p21 chromosomal region is a rare cause of Lynch syndrome, but presents with distinct phenotypic features, highlighting the need for recognition and awareness of this syndromic entity.

  20. Japan in the 21st Century Geopolitics

    2015-06-01

    Full Text Available In 1853, Japan was forced to come out of its feudal isolation and become a part of the worldwide business network. Its opening up did not mean surrendering to external powers, but rather becoming immersed in an imperialist struggle, from which it would come out defeated in 1945. Nevertheless, Japan’s prostration was temporary, given that in the post-war period it became an unconditional ally of the same super power that had blocked its military aspirations with two atomic bombs. The strategic agreement with the USA remained intact even after the Cold War had ended. Moreover, the verbal struggle and show of frce in the Senkaku / Diaoyutai Islands, in 2012, facilitated a return to power which was more akin to the dictates of Washington and its security plan in the Pacific political wing. Today, the confrontation in Northeast Asia presents the Korean-American-Japanese block, on one side, and the Sino-Russian-North Korean, on the other, on a fork which must be seen as a new bipolar scheme which will guarantee the regional strategic equilibrium. However, progressive changes are expected in the balance of power in both the Asian sector and the rest of the world, due to the impact of growing Chinese economic, political and military power on geopolitical agreements, including the Japanese-American one.

  1. Jesuit strategy in Japan and India in the 16th Century as a precursor to modern Western “Soft Power”

    2017-12-01

    Full Text Available The principles of “soft power”, within the context of the historical development of international relations both on the worldwide and regional levels, had been applied in the East and in the West long before the aforementioned theories appeared. It was the Jesuits in the 16th Century who developed strategies of influence and were pioneers in the introduction of “soft” methods of leverage in international communication practice. In today’s world, which is witnessing an increase in the role of the religious factor in international relations, it is important to understand how to identify these achievements, and correct the mistakes of these early strategies, based on the practices of Francis Xavier in Japan and of Antoni de Montserrat in the Mughal Empire. An attentive and thorough study of the Jesuits’ experience is of great importance in understanding contemporary processes of international interaction from a “soft power” point of view.

    Full Text Available Abstract Background Cyclins regulate the cell cycle in association with cyclin dependent kinases (CDKs. CDKs are under inhibitory control of cyclin dependent kinase inhibitors (CDKIs. Method In this study we tested the expression of CDKIs p15, p16, p21 and p27 by immunohistochemistry to determine the role of CDKIs in the initiation of primordial follicle growth. Ovaries were collected from 60-day-old cycling B6D2F1/J mice (n = 16. Results Expression of p15, p16, p21 and p27 did not vary in granulosa and theca cells by the follicle stage. However, p16 staining was stronger (++ in the oocytes of all primordial, and 57.4 ± 3.1% of primary follicles compared to the remaining primary and more advanced follicles (+. Interestingly, primary follicles with weaker (+ oocyte staining for p16 had significantly larger mean follicle diameter compared to the primary and primordial follicles with stronger (++ oocyte staining (55.6 ± 2.1 vs. 32.0 ± 1.0 and 26.5 ± 0.7 μm, respectively, p Conclusions These preliminary findings suggest that the initiation of oocyte growth, which seems to lead follicle growth, is associated with diminished p16 expression in the mouse ovary. Further studies are needed to investigate the factors that regulate the expression of p16 in the oocyte, which might also govern the initiation of primordial follicle growth.

ISAMMA is the first consolidated symposium of three independent symposia held in the Asian region. ISPMM (International Symposium on Physics of Magnetic Materials) of Japan started in 1987 in Sendai, and was held six times: Beijing (1992), Seoul (1995), Sendai (1998), Taipei (2001) and Singapore (2005). ISAMT (International Symposium of Advanced Magnetic Technology) of Taiwan and SOMMA (International Symposium on Magnetic Materials and Applications) of Korea both began in 1999 and were each held five times up to 2005. ISAMMA was established as a new international symposium which will be held every three years in Asia. The concept of this unified international symposium was mainly led by Professor M Takahashi, Conference Chair of ISAMMA 2010. The first memorial symposium, ISAMMA 2007, was held in Jeju Island, Korea, during the period from 28 May to 1 June 2007. The main purpose and scope of ISAMMA is to provide an opportunity for scientists and engineers from all over the world to meet in Asia to discuss recent advances in the study of magnetic materials and their physics, spin-related phenomena and materials. The categories of ISAMMA 2010 were: fundamental properties of magnetic materials; hard/soft magnetic materials and applications; spintronics materials and devices; structured materials; multi functional magnetic materials; spin dynamics and micromagnetics; magnetic storage; materials for applications (sensors, high-frequency, power, and bio/medical devices); magnetic imaging and characterization. The scientific programme began on Tuesday 13 July 2010 with the opening remark by the Symposium Chairman. The conference was attended by 511 participants from 23 countries, with about 40 per cent from

    1. Nuclear 2007 highlights: - A magnitude 6.8 earthquake occurred in Niigata on July 16 2007. Owing to this earthquake, 3 units operating and 1 unit during start-up were shutdown automatically at TEPCO's Kashiwazaki-Kariwa NPS. Now, all 7 units of the NPS are in an outage for investigation. This influenced the capacity factor of Japanese NPPs in FY 2007, which stood at just 60.7%. - Debate on global warming is more and more active in Japan, as it is the host country of the G8 Hokkaido Toyako Summit in July. The Japan Atomic Energy Commission released 'White Paper on Nuclear Energy 2007' in March 2008. In the paper, they first expressed the view that the expansion of the peaceful use of nuclear energy is indispensable. 2. Nuclear overview: a. Energy policy: Electricity share: 25.4% of nuclear. The energy policy of Japan aims at nuclear power generation being maintained at the current level (30 to 40% of the total electricity generation) or increasing even after 2030, for stable energy supply and as a countermeasure against global warming. - Nuclear Fuel Cycle: The active tests at the JNFL reprocessing plant in Rokkasho-mura are in the final phase for commercial operation in 2008. By FY 2010 Plutonium utilization in LWRs in 16 to 18 NPP units. Around FY 2010 Installment of new centrifuges at the uranium enrichment plant at Rokkasho-mura.

    Japan Congenital Cardiovascluar Surgical Database (JCCVSD) is a nationwide registry whose data are used for health quality assessment and clinical research in Japan. We evaluated the completeness of case registration and the accuracy of recorded data components including postprocedural mortality and complications in the database via on-site data adjudication. We validated the records from JCCVSD 2010 to 2012 containing congenital cardiovascular surgery data performed in 111 facilities throughout Japan. We randomly chose nine facilities for site visit by the auditor team and conducted on-site data adjudication. We assessed whether the records in JCCVSD matched the data in the source materials. We identified 1,928 cases of eligible surgeries performed at the facilities, of which 1,910 were registered (99.1% completeness), with 6 cases of duplication and 1 inappropriate case registration. Data components including gender, age, and surgery time (hours) were highly accurate with 98% to 100% concordance. Mortality at discharge and at 30 and 90 postoperative days was 100% accurate. Among the five complications studied, reoperation was the most frequently observed, with 16 and 21 cases recorded in the database and source materials, respectively, having a sensitivity of 0.67 and a specificity of 0.99. Validation of JCCVSD database showed high registration completeness and high accuracy especially in the categorical data components. Adjudicated mortality was 100% accurate. While limited in numbers, the recorded cases of postoperative complications all had high specificities but had lower sensitivity (0.67-1.00). Continued activities for data quality improvement and assessment are necessary for optimizing the utility of these registries.

  6. Nuclear fuel cycle in Japan : status and perspective

    1996-01-01

    Nearly one third of electricity in Japan is being generated by nuclear fission primarily by light-water reactors. The industries to supply uranium fuel for these reactors have been well established including the capability for uranium enrichment. From the onset of nuclear program in Japan, a country with thin energy resources, the emphasis has been placed on maximizing the efficiency of uranium utilization. Thus the national nuclear program set forth by the Japan Atomic Energy Commission has consistently called for the establishment of closed fuel cycle, or for recycling of nuclear fuel. As part of such efforts in private sectors, the first commercial reprocessing plant is now under construction at Rokkasho-mura. The program to develop technologies for recycling nuclear fuel in a fast reactor system is also in progress steadily under the governmental support, while the Monju accident casts a long shadow on the future of fast reactor development in Japan. Even though the price of uranium has been stable at relatively low level in recent years, the uranium market in the longer time range is somewhat unpredictable. In Asian countries, a rapid growth of nuclear power production is foreseen in the 21st century. Under such circumstances, the effort to pursue the recycling option in Japan is important not only for its own energy security but also for stabilization of future uranium market in the world. The recycling option can also offer more flexible, easier and safer ways of radioactive waste management. Since the recycling option means utilization of plutonium in an industrial scale, special attention is inevitably required from the viewpoint of nuclear non-proliferation. It is the Japan's national policy to develop recycling technologies in compliance with the NPT and IAEA safeguard system as well as to maintain the transparency of its developmental program.

    Full Text Available Genetic polymorphisms of CYP1A2 is related to the theophylline metabolism that may affect drug levels in the blood, which can also affect incidence of adverse drug reaction (ADR and clinical outcomes of asthma therapy. The frequency of CYP1A2 polymorphism is known to vary among ethnic. Allegedly the Indonesian population has high frequency of gene variants of CYP1A2*1F. This study aims to determine the profile of CYP1A2*1F gene polymorphism in a sample of nonasthma and asthma in Indonesia with other populations based on the literature. Data were taken on January–June 2014. Blood samples were obtained from 29 nonasthma samples and 16 patients with asthma. After extraction of genomic DNA, CYP1A2*1F gene polymorphisms determined by PCR-RFLP. The results of this study indicate that the CYP1A2*1F gene polymorphism in nonasthma samples was 10.35% (3/29 for C/C, 37.93% (11/29 for the C/A, and 51.72% (15/29 for A/A. The asthmatics genotype have a frequency distribution of C/A genotype of 81.25% (13/16 and A/A of 18.75% (3/16. There was no significant difference (p=0.276 allele frequencies between samples of nonasthma and asthma patients. The frequency of CYP1A2*1F gene in Indonesian population is higher than the population of Egypt, Japan, and UK, but lower compared to Malaysia. It can be concluded that there is no difference in frequency.

    Water masses in the subsurface and the intermediate layer are actively formed due to strong winter convection in the Japan Sea. It is probable that some fraction of pollution is carried into the layer below the sea surface together with these water masses, so it is important to estimate the formation rate and turnover time of water masses to study the fate of pollutants. The present study estimates the annual formation rate and the turnover time of water masses using a three-dimensional ocean circulation model and a particle chasing method. The total annual formation rate of water masses below the sea surface amounted to about 3.53±0.55 Sv in the Japan Sea. Regarding representative intermediate water masses, the annual formation rate of the Upper portion of the Japan Sea Proper Water (UJSPW) and the Japan Sea Intermediate Water (JSIW) were estimated to be about 0.38±0.11 and 1.43±0.16 Sv, respectively, although there was little evidence of the formation of deeper water masses below a depth of about 1500 m in a numerical experiment. An estimate of turnover time shows that the UJSPW and the JSIW circulate in the intermediate layer of the Japan Sea with timescales of about 22.1 and 2.2 years, respectively. (author)

    To investigate the current status of portal vein thrombosis (PVT) in Japan, the Clinical Research Committee of the Japan Society of Portal Hypertension undertook a questionnaire survey. A questionnaire survey of 539 cases of PVT over the previous 10 years was carried out at institutions affiliated with the Board of Trustees of the Japan Society of Portal Hypertension. The most frequent underlying etiology of PVT was liver cirrhosis in 75.3% of patients. Other causes included inflammatory diseases of the hepatobiliary system and the pancreas, malignant tumors, and hematologic diseases. The most frequent site was the main trunk of the portal vein (MPV) in 70.5%, and complete obstruction of the MPV was present in 11.5%. Among the medications for PVT, danaparoid was given to 45.8%, warfarin to 26.2%, heparin to 17.3%, and anti-thrombin III to 16.9%. Observation of the course was practiced in 22.4%. Factors contributing to therapeutic efficacy were implementation of various medications, thrombi localized to either the right or left portal vein only, non-complete obstruction of the MPV and Child-Pugh class A liver function. A survival analysis showed that the prognosis was favorable with PVT disappearance regardless of treatment. The questionnaire survey showed the current status of PVT in Japan. Any appropriate medication should be given to a patient with PVT when PVT is recognized. It is necessary to compile a large amount of information and reach a consensus on safe and highly effective management of PVT. © 2017 The Japan Society of Hepatology.

    bystander cardiopulmonary resuscitation (CPR) is performed infrequently in Japan. We conducted this study to identify Japanese attitudes toward the performance of bystander CPR. participants were asked about their willingness to perform CPR with varying scenarios and CPR techniques (mouth-to-mouth ventilation plus chest compression (MMV plus CC) versus chest compression alone (CC)). a total of 1302/1355 individuals completed the questionnaire, including high school students, teachers, emergency medical technicians, medical nurses, and medical students. About 2% of high school students, 3% of teachers, 26% of emergency medical technicians, 3% of medical nurses and 16% of medical students claimed they would 'definitely' perform MMV plus CC on a stranger. However, 21-72% claimed they would prefer the alternative of performing CC alone. Respondents claimed their unwillingness to perform MMV is not due to the fear of contracting a communicable disease, but the lack of confidence in their ability to perform CPR properly. in all categories of respondents, willingness to perform MMV plus CC for a stranger was disappointingly low. Better training in MMV together with teaching awareness that CC alone can be given should be instituted to maximize the number of potential providers of CPR in the community, even in communities where the incidence of HIV is very low.

    One of the alcohol-related goals in Japan's health promotion campaign called Health Japan 21 (secondary term) is to reduce the number of high-risk drinkers (20 years old or above) who consume 40g or more pure alcohol/day in men and 20g or more in women by year 2022. To achieve this goal, a further expansion of screening and brief intervention (SBI) in the medical setting is essential. In this research, realistic and cost-effective SBI scenarios in Japan were investigated based on international systematic review and clinicians' opinions from a semi-structured interview. Several SBI scenarios were built with 2 levels of intervention based on the AUDIT scores of 8-15 (brief advice) and 16-19 (brief advice and counseling, continuous intervention), and a simulation was conducted by applying different probabilities and success rates into the scenarios. Information associated with preparation and implementation of SBI at the 2 levels was also estimated and annual costs of SBI per drinker were calculated. It was found that approximately 2,390,000 and 530,000 high-risk drinkers require brief and extensive interventions, respectively. Furthermore, incremental costs per quality-adjusted life year (QALY) gained were calculated at 723,415 yen for brief intervention and 944,762 yen for extensive intervention, suggesting cost-effectiveness of SBI in Japan. Given the limited national healthcare budget and operational challenges such as time to provide SBI especially in the primary care setting in Japan, roles of healthcare providers and wider use of information technology were discussed with some suggestions. Furthermore, lighter and more frequent interventions at various levels and not only at the medical setting but also at multiple social settings (such as workplace and among family and friends) were discussed to increase the cost-effectiveness of SBI and to keep the number of high-risk drinkers who have successfully reduced their alcohol consumption.

    To clarify the problems related to maternal deaths in Japan, including the diseases themselves, causes, treatments and the hospital or regional systems. Descriptive study. Maternal death registration system established by the Japan Association of Obstetricians and Gynecologists (JAOG). Women who died during pregnancy or within a year after delivery, from 2010 to 2014, throughout Japan (N=213). The preventability and problems in each maternal death. Maternal deaths were frequently caused by obstetric haemorrhage (23%), brain disease (16%), amniotic fluid embolism (12%), cardiovascular disease (8%) and pulmonary disease (8%). The Committee considered that it was impossible to prevent death in 51% of the cases, whereas they considered prevention in 26%, 15% and 7% of the cases to be slightly, moderately and highly possible, respectively. It was difficult to prevent maternal deaths due to amniotic fluid embolism and brain disease. In contrast, half of the deaths due to obstetric haemorrhage were considered preventable, because the peak duration between the initial symptoms and initial cardiopulmonary arrest was 1-3 h. A range of measures, including individual education and the construction of good relationships among regional hospitals, should be established in the near future, to improve primary care for patients with maternal haemorrhage and to save the lives of mothers in Japan.

    Septic arthritis (SA) cases can result in claims or litigation because of poor prognosis even if it is unavoidable. Although these claims or litigation are useful for understanding causes and background factors of medical errors, the characteristics of malpractice claims associated with SA remain undetermined in Japan. This study aimed to increase our understanding of malpractice claims in the clinical management of SA. We analyzed 6 civil precedents and 16 closed claims of SA from 8530 malpractice claims processed between July 2004 and June 2014 by the Tokyo office of Sompo Japan Nipponkoa Insurance, Incorporated. We also studied 5 accident and 21 incident reports of SA based on project data compiled by the Japan Council for Quality Health Care. The rate of negligence was 83.3% in the precedents and 75.0% in closed claims. Two main malpractice claim patterns were revealed: SA in a lower extremity joint following sepsis caused by methicillin-resistant Staphylococcus aureus in newborns and SA in an injection site following joint injection. These two patterns accounted for 83.3% and 56.3% of judicial cases and closed claim cases, respectively. Breakdowns in care process of accident and incident reports were clearly differentiated from judicial cases or closed claim cases (Fisher's exact test, p < 0.001). It is important to pay particular attention to SA following sepsis in newborns and to monitor for any signs of SA after joint injection to ensure early diagnosis. Analysis of both malpractice claims and accident and incident reports is essential to ensure a full understanding of the situation in Japan. Copyright © 2017. Published by Elsevier Taiwan LLC.

    More and more evidences have ensured the crucial functions of long non-coding RNAs (lncRNAs) in multiple tumors. It has been discovered that lncRNA-SNHG16 is involved in many tumors. Even so, it is still necessary to study SNHG16 comprehensively in bladder cancer. In terms of our study, the level of SNHG16 both in the tumor tissues and cell lines was measured and the relationship among SNHG16, clinicopathological traits and prognosis was explored. Interference assays were applied to determine the biological functions of SNHG16. It was discovered that the level of SNHG16 was evidently enhanced both in tissues and cell lines of bladder cancer. Patients with highly expressed SNHG16 suffered from poor overall survival. Multivariable Cox proportional hazards regression analysis implied that highly expressed SNHG16 could be used as an independent prognostic marker. It could be known from functional assays that silenced SNHG16 impaired cell proliferation, owing to the effects of SNHG16 on cell cycle and apoptosis. Finally, mechanism experiments revealed that SNHG16 could epigenetically silence the expression of p21. The facts above pointed out that lncRNA-SNHG16 might be quite vital for the diagnosis and development of bladder cancer, and could even become an important therapeutic target for bladder cancer.

    Full Text Available Abstract Background Understanding the pathophysiology of chemokine secretion in endometriosis may offer a novel area of therapeutic intervention. This study aimed to identify chemokines differentially expressed in epithelial glands in eutopic endometrium from normal women and those with endometriosis, and to establish the expression profiles of key chemokines in endometriotic lesions. Methods Laser capture microdissection isolated epithelial glands from endometrial eutopic tissue from women with and without endometriosis in the mid-secretory phase of their menstrual cycles. Gene profiling of the excised glands used a human chemokine and receptor cDNA array. Selected chemokines were further examined using real-time PCR and immunohistochemistry. Results 22 chemokine/receptor genes were upregulated and two downregulated in pooled endometrial epithelium of women with endometriosis compared with controls. CCL16 and CCL21 mRNA was confirmed as elevated in some women with endometriosis compared to controls on individual samples. Immunoreactive CCL16 and CCL21 were predominantly confined to glands in eutopic and ectopic endometrium: leukocytes also stained. Immunoreactive CCL16 was overall higher in glands in ectopic vs. eutopic endometrium from the same woman (P Conclusion This study provides novel candidate molecules and suggests a potential local role for CCL16 and CCL21 as mediators contributing to the inflammatory events associated with endometriosis.

    Full Text Available Bacillus sp. GA2(1 and Bacillus sp. GA1(6 were isolated from soybean field in Khon Kaen province, Thailand. Crude enzymes from both isolates showed the activities of cellulase, xylanase, and mannanase at 37°C for 24 h. The highest xylanase activities of Bacillus sp. GA2(1 and Bacillus sp. GA1(6 were 1.58±0.25 and 0.82±0.16 U/ml, respectively. The relative xylanase activities from both strains were more than 60% at pH 5.0 to 8.0. The optimum temperature of xylanases was 50°C in both strains. The residual xylanase activities from both strains were more than 70% at 60°C for 60 min. Five agricultural wastes (AWs, namely coffee residue, soybean meal, potato peel, sugarcane bagasse, and corn cobs, were used as substrates for hydrolysis properties. The highest reducing sugar content of 101±1.32 µg/ml was obtained from soybean meal hydrolysate produced by Bacillus sp. GA2(1 xylanase.

We investigated the use of traditional Chinese medicine (TCM for the treatment of intractable anemia. Method: Placenta Hominis (PH, steam boiled and roasted, and Cervi Cornus Colla (deer antler glue has been used in China for hundreds of years to treat anemia. After consent was obtained, we prescribed these two materials for a 74-year-old female with aplastic anemia and a 26-year-old male with presumably a virus-induced anemia. Concomitant conventional therapy was continued in both patients as prescribed by their respective attending physicians. Conclusion: Conventional therapy with steroid hormones, immunosuppressive drugs, platelet and erythrocyte transfusions were not effective in these patients. In addition, both patients suffered from serious side effects. In two patients, ingestion of Placenta Hominis and Cervi Cornus Colla with TCM prescriptions increased the platelet and enhanced the hemoglobin concentration in several months of therapy accompanied by a dramatic improvement in quality of life. The addition to conventional therapy of PH and Cervi Cornus Colla, the latter of which is very easy to obtain, may be one of the potentially advantageous choices in case of otherwise intractable anemia.Keywords: placenta, antler glue, Cervi Cornus Colla, anemia, aplastic anemia

    The 5th World Congress on Biomimetics, Artificial Muscles and Nano-Bio and the 4th International Conference on Artificial Muscles were held in Osaka, Japan, 23-27 November 2009. This special section of Smart Materials and Structures is devoted to a selected number of research papers presented at this international conference and congress. Of the 76 or so papers presented at the conference, only 10 papers were finally selected, reviewed and accepted for this special section, following the regular reviewing procedures of the journal. This special section is focused on polymeric artificial muscles, electroactive polymers, multifunctional nanocomposites and their applications. In particular, an electromechanical model for self-sensing ionic polymer-metal composite actuating devices with patterned surface electrodes is presented which discusses the concept of creating self-sensing ionic polymer-metal composite (IPMC) actuating devices with patterned surface electrodes where actuator and sensor elements are separated by a grounded shielding electrode. Eventually, an electromechanical model of the device is also proposed and validated. Following that, there is broad coverage of polytetrahydrofurane-polyethylene oxide-PEDOT conducting interpenetrating polymer networks (IPNs) for high speed actuators. The conducting polymer (poly(3,4-ethylenedioxythiophene)) is incorporated within the IPNs, which are synthesized from polyethylene oxide (PEO)/polytetrahydrofurane (PTHF) networks. PEO/PTHF IPNs are prepared using poly(ethylene glycol) methacrylate and dimethacrylate and hydroxythelechelic PTHF as starting materials. The conducting IPN actuators are prepared by oxidative polymerization of 3,4-ethylenedioxithiophene (EDOT) using FeCl3 as an oxidizing agent within the PEO/PTHF IPN host matrix. Subsequently, giant and reversible magnetorheology of carrageenan/iron oxide magnetic gels are discussed and the effect of magnetic fields on the viscoelastic properties

    During the one hundred years and more from the beginning of the 18th century to the beginning of the 19th century, about 16 Chinese doctors, at the invitation of Japanese, went to Japan successively by trade ships to practice medicine and teach Chinese medicine. They also conducted academic exchanges with Japanese doctors. Because both the Japanese authorities of that time and the emperor of Qing dynasty implemented the policy of closing the country, they could only do things in certain areas within limited time. By consulting a vast amount of data and following the footprints of some of the Chinese doctors in Japan, the author has got things into shape about the comings and goings of the doctors who went to Japan during the century and their activities, with the stressed point laid on the achievements of such influential doctors as Zhu Laizhang, Zhu Zizhang, Zhou Qilai, Zhao Songyang, Li Renshan, Hu Zhaoxin and so on.

    Indoor radon concentrations of 792 houses in Osaka, Nara, Wakayama and Hyogo were measured by the passive dosemeter which was developed in Karlsruhe Nuclear Research Center in West Germany. Each house was measured at two places for successive two periods of six months to obtain annual average exposure due to radon daughters. The arithmetic mean concentration of all houses was 45.2 Bq/m 3 with a standard deviation of 27.2; the geometric mean, 40.7 Bq/m 3 and the median, 39 Bq/m 3 . The distribution of the radon levels was approximately log-normal with 80% of houses having radon concentrations less than 60 Bq/m 3 . The seasonal variation of the mean radon concentration was evident between the former period including winter value of 45 Bq/m 3 and the latter including summer value of 32 Bq/m 3 . The indoor radon concentrations of wooden houses were found to have the widest distribution with the highest value of 371 Bq/m 3 . The highest value obtained in the ferro-concrete house was 118 Bq/m 3 . Twelve houses having indoor radon concentrations higher than 120 Bq/m 3 were all Japanese traditional wooden houses with walls made of soil. (author)

Coronary flow reserve (CFR is a physiological index of coronary microcirculation and is noninvasively measured by transthoracic Doppler echocardiography (TTDE. This study aimed to investigate the effects of RIC on CFR in healthy subjects and patients with HF, through the assessment by TTDE. Methods: Ten patients with HF with left ventricular ejection fraction of less than 40%, and ten healthy volunteers were enrolled in this study. RIC treatment was performed twice a day for 1 week. Our custom-made RIC device was programmed to automatically conduct 4 cycles of 5 minutes inflation and 5 minutes deflation of a blood pressure cuff to create intermittent arm ischemia. CFR measurements and laboratory tests were examined before, and after 1 week of RIC treatment. Results: One week of RIC treatment was well tolerated in both groups. RIC treatment increased CFR from 4.0±0.9 to 4.6±1.3 (mean ± standard deviation in healthy subjects (P=0.02, and from 1.9±0.4 to 2.3±0.7 in patients with HF (P=0.03, respectively. Systolic blood pressure in healthy subjects, and heart rate in HF patients decreased after RIC treatment (both P<0.01.

    2016-01-01

    This paper examines the implication and detail of the agreement of COP 21, and clarifies the task for electric power companies and the direction of development based on this. In face of the formulation of energy mix policy for 2030, in July 2015, Japan established a greenhouse gas reduction target of 25% compared to 2013, and registered it. Although the goal for achieving a low-carbon society has been completed by setting energy saving target and energy mix policy, how to realize it during the progress of power system innovation is important and it is not easy. As the energy policy, the following are important: (1) steady realization of energy saving, (2) cost reduction and balancing of introduction of renewable energy, (3) clean use of fossil fuels, and (4) ensuring the safety of nuclear power and steady restart. This study discusses what will be made for each item, and what will be needed. To make Japan's efforts toward a low-carbon society a reality, the securement of zero-emission power sources of 44% is indispensable, and 20% to 22% (a little less of half of it) is expectedly depending on nuclear power. With the Paris Agreement at COP 21, the buildup of a low-carbon society in Japan is now an urgent issue. However, there are various hurdles for realizing it, and in addition, the system innovation of electric power business has entered a full-fledged stage, making the task further complicated. (A.O.)

    Human Resource Development was the first and remains an important pillar in Japanese foreign aid. I will argue that Japan has access to a global network of alumni who will co-define Japanese foreign aid in the future, because Japan has encouraged alumni societies and networking since 1965. A total...... of more than a million people in more than 100 countries have attended courses in Japan funded fully or partly by Japanese ODA since the inception of the technical assistance programs in 1954 through the Colombo Plan and since 1959 through the Association of Overseas Technical Scholarships (AOTS from 2009...... HIDA). Many of these alumni have and will in the future exchange ideas and keep contact not only to Japan, but also to fellow alumni around the globe and, thereby, practice south-south exchanges, which are made possible and traceable by their established alumni network and the World Network of Friends...

Prospective, multicenter, noninterventional, observational study across geographic distribution of both private and public institutions for patients with RA who are newly prescribed one of the following medications: (1) methotrexate; (2) anti-TNF biologic DMARDs; (3) non-TNF biologic DMARDs; and (4) approved JAK inhibitors at the time of enrollment into the registry. Target enrollment is currently 2000 subjects. Baseline and follow-up data on patient demographics, medical history, disease activity, laboratory results, comorbidities, hospitalizations, and targeted safety events are obtained via Physician and Patient Questionnaires. Fifty sites are anticipated to participate with 40 sites ethics committee (EC) approved at the time of submission consisting of 23% clinics, 21% private academic hospitals, 29% private mid-sized to large hospitals, 15% national academic hospitals, and 12% national hospitals. The Corrona Japan RA Registry will provide real-world evidence from both private and public institutions on the comparative effectiveness and safety of recently approved RA therapies in Japan.

    The seasonal variation of semidiurnal internal tides in the East/Japan Sea was investigated using 25 month long output from a real-time ocean forecasting system. The z coordinate eddy-resolving high-resolution numerical model, called the RIAM ocean model, incorporates data assimilation that nudges temperature and salinity fields together with volume transport through the Korea Strait to produce realistic oceanic currents and stratification. In addition to atmospheric forcing, it includes tidal forcing of 16 major components along open boundaries. The model generates energetic semidiurnal internal tides around the northern entrance of the Korea Strait. Energy conversion from barotropic to baroclinic (internal) tides varies seasonally with maxima in September (ranging 0.48-0.52 GW) and minima in March (ranging 0.11-0.16 GW). This seasonal variation is induced by the seasonality in stratification near the southwestern East/Japan Sea. The propagation distance of the internal tides is associated with generation intensity and wavelength. From late summer to early winter, the semidiurnal internal tides travel relatively far from the generation region due to stratification changes; its energy dissipates less as a result of longer wavelengths. Our results suggest that spatiotemporal variation of internal-tide-induced mixing due to the seasonality in the generation, propagation, and dissipation of internal tides should be considered for a more realistic simulation of water masses and circulation in models of the East/Japan Sea.

    The naturally occurring anthraquinone emodin has been serving primarily as an anti-bacterial and anti-inflammatory agent. However, little is known about its potential on anti-aging. This investigation examined the effect of emodin on lifespan and focused on its physiological molecular mechanisms in vivo. Using Caenorhabditis elegans (C. elegans) as an animal model, we found emodin could extend lifespan of worms and improve their antioxidant capacity. Our mechanistic studies revealed that emodin might function via insulin/IGF-1 signaling (IIS) pathway involving, specifically the core transcription factor DAF-16. Quantitative RT-PCR results illustrated that emodin up-regulated transcription of DAF-16 target genes which express antioxidants to promote antioxidant capacity and lifespan of worms. In addition, attenuated effect in sir-2.1 mutants suggests that emodin likely functioned in a SIR-2.1-dependent manner. Our study uncovers a novel role of emodin in prolonging lifespan and supports the understanding of emodin being a beneficial dietary supplement.

    In the Tokai No. 2 power plant of the Japan Atomic Power Company, about 80% of the annual dose equivalent is received during periodic maintenance outages. A project group for dose reduction was organized at the company`s headquarters in 1986; in 1988, they proposed a five-year program to reduce by half the collective dose of 4 person-Sv per normal outage work. To achieve the target dose value, some dose-reduction measures were undertaken, namely, permanent radiation shielding, decontamination, automatic, operating machines, and ALARA organization. As the result, the collective dose from normal outage work was 1.6 person-Sv in 1992, which was less than the initial target value.

    The population structure of the Pacific cod Gadus macrocephalus was examined using 15 microsatellite loci and mitochondrial DNA (ND2 region). In total, 274 individuals were sampled from 16 locations around Japan to estimate the level of genetic differentiation and effective population size (N e ). Pairwise F ST , analysis of molecular variance and Bayesian clustering analysis suggested the presence of two genetically distinct groups in waters around Japan, with a higher N e value in the eastern group than in the western group. A possible factor that restricts gene flow between groups may be related to the water temperature differences in the south-western part of the Sea of Japan, where the Tsushima Warm Current flows around the area inhabited by the western group, which may limit migration between the west and east. © 2016 The Fisheries Society of the British Isles.

    Full Text Available Background. Treatment and management strategies for asthma in children are generally consistent internationally, but prescription of antiasthma drugs differs among countries. The objective of this study was to examine the prescribing patterns of antiasthma drugs, particularly controller medications, in children. Methods. A retrospective cohort study was performed in children with asthma using an administrative claims database in Japan. Results. A total of 1149 preschool-age and 3226 school-age children were identified. Leukotriene receptor antagonists were prescribed for about 80% of the children. Long-acting β-agonists were prescribed for 87.6% and 59.6% of preschool-age and school-age children, respectively, whereas prescriptions of inhaled corticosteroids had lower rates of 8.2% and 16.5%, respectively. In an examination of prescriptions at 1-month intervals, a relatively high number of children were prescribed bronchodilators without anti-inflammatory agents. Conclusion. Our findings suggest that asthma care for children in Japan can be improved through changes in drug prescriptions.

  13. Reconsidering Japan's underperformance in pharmaceuticals: evidence from Japan's anticancer drug sector.

    Science.gov (United States)

    Umemura, Maki

    2010-01-01

    Unlike its automobile or electronics industries, Japan's pharmaceutical industry did not become a global leader. Japan remains a net importer of pharmaceuticals and has introduced few global blockbuster drugs. Alfred Chandler argued that Japan's pharmaceutical firms remained relatively weak because Western firms enjoyed an insurmountable first first-mover advantage. However, this case study of the anticancer drug sector illustrates that Chandler's explanation is incomplete. Japanese medical culture, government policy, and research environment also played a substantial role in shaping the industry. In the 1970s and 1980s, these factors encouraged firms to develop little few effective drugs with low side effects, and profit from Japan's domestic market. But, these drugs were unsuitable to foreign markets with more demanding efficacy standards. As a result, Japan not only lost more than a decade in developing ineffective drugs, but also neglected to create the infrastructure necessary to develop innovative drugs and build a stronger pharmaceutical industry.

  14. An unofficial history of Japanese accelerators. Part 1

    History of charged particle accelerators in Japan is reviewed. The nuclear reaction by an accelerator was observed first in 1934 at Taipei in Taiwan, which was a colony of Japan at that time. Before the world war II, three cyclotrons were built at Institute of Physics and Chemistry Research, Osaka University and Kyoto University. After the war, the cyclotrons were destroyed by the occupation army. The construction of accelerators was restarted at 1951, and synchrotrons, betatrons, Van de Graaff accelerators, Cockcroft-Walton accelerators as well as cyclotrons were built at various universities and institutes. To be operated and used by the nuclear physicists from all over Japan, a large-scale accelerator facility, Institute for Nuclear Study, was founded at University of Tokyo. (K.Y.)

  15. Inactivation of the P16INK4/MTS1 gene by a chromosome translocation t(9;14)(p21-22;q11) in an acute lymphoblastic leukemia of B-cell type.

    Duro, D; Bernard, O; Della Valle, V; Leblanc, T; Berger, R; Larsen, C J

    1996-02-15

    We have reported previously a preliminary study of a t(9;14)(p21-22; q11) in B-cell acute lymphoblastic leukemia. This translocation had rearranged the TCRA/D locus on chromosome band 14q11 and the locus encoding the tumor suppressor gene P16INK4/MTS1 (P16) on band 9p21 (D. Duro et al., Oncogene, 11: 21-29, 1995). In the present report, the breakpoints were precisely localized on each chromosome partner. On the 14q- derivative, the sequence derived from chromosome 9 was interrupted at 1.0 kb upstream of the first exon of P16, close to a consensus recombination heptamer, CACTGTG. In addition, the chromosome 14 breakpoint was localized at the end of the TCRD2 (delta 2) segment, and 22 residues with unknown origin were present at the translocation junction. On the 9p+ derivative, chromosome 9 sequences were in continuity with those displaced onto chromosome 14, and the 14q11 breakpoint was located within TCRJA29 segment. These features are consistent with aberrant activity of the TCR gene recombinase complex. Although all three coding exons of P16 were displaced onto the chromosome 14q-derivative, no P16 transcript was detected in the leukemic cells. Because the region spanning the P16 exon 1 was not inactivated by methylation and because the other P16 allele was deleted, the implication is that the chromosome breakpoint was likely to disrupt regulatory elements involved in the normal expression of the gene. As a whole, then, our results show that translocations affecting band 9p21 can participate to the inactivation of P16, thus justifying a systematic survey of translocations of the 9p21 band in acute lymphoblastic leukemia.

    It is considered that the development of BWR plants in Japan has been advanced relatively smoothly though sometimes there were complications. As of the end of fiscal year 1986, the BWR plants in operation were 16, and the total power output amounted to 12,917 MW, which was equivalent to 8 % of 153 GW of the total power source facilities in Japan. Reflecting the excellent operational result of BWR plants, the generated electric power in fiscal year 1986 reached 85.9 TWh and about 15 % of the total, exceeding hydroelectric power. This means that about 18 million tons of petroleum import was reduced. At the initial stage, BWR plants suffered the stress corrosion cracking of stainless steel pipings in the reactor primary system. This trouble was successfully solved by the efforts of the government, electric power companies, plant manufacturers and research institutes. In fiscal year 1983, the capacity factor of all BWR plants in Japan recovered to more than 70 %, and in fiscal year 1986, it has reached 75.9 %. In order to improve the capacity factor further, it is necessary to prevent troubles by the development of diagnostic techniques and preventive maintenance, and to shorten regular inspection period. The change of accidents and troubles, the measures to reduce regular inspection period, the reduction of radiation exposure, and the reduction of wastes are reported. (Kako, I.)

    It is significant to internationally develop the nuclear power plants technology that has been fostered by Japan's nuclear industry. It is also important to work with taking the degree of development of nuclear power plants of the recipient country into consideration. ''Forum on International Development of Nuclear Industry'' organized by the Japan Atomic Industrial Forum, Inc. (JAIF) proposed it would be indispensable for a Japan's nuclear industry to establish a Japan-U.S. Cooperation with the support of Government in order to develop the nuclear technology internationally. In November 2005, the investigating team including utilities and nuclear industry visited U.S. and exchanged opinions on its possibility. Investigating results and their evaluation were described.

    Despite widespread use of sedation for stress management during dental treatment in adults, its prevalence of use for pediatric in patients Japan has not been clarified. We investigated here, the present situation of pediatric sedation by the questionnaire sent to the dental anesthesia departments of university hospitals in Japan. Postal survey was conducted of the dental anesthesia departments of university hospitals (29 institutions) throughout the country. Information was requested on hospital policy of indication and technique of pediatric sedation for dental treatment. The causes for avoiding pediatric sedation were also investigated. The response rate was 86.2% (25/29 institutions). Of these respondents, 16 institutions (64%, 16/25 institutions) employ sedation for pediatric dental treatment stress management. The cases performed were around 1-5 cases every month. However, the criteria for employment of pediatric sedation during dental treatment varied among institutes. They preferred to provide general endotracheal anesthesia for pediatric dental procedures, and tended to avoid sedation without airway security for children. The present survey suggests that pediatric sedation for stress management during dental treatment are employed in more than half of the dental university hospitals. However, there was little consensus regarding pediatric sedation during dental treatment among dental anesthesiologists in Japan.

However, optimization of the release rate in polymeric micellar nanoscale drug delivery systems has not been fully investigated. In this study NC-6301, a poly(ethylene glycol-poly(aspartate block copolymer with docetaxel (DTX covalently bound via ester link, was synthesized with various numbers of DTX molecules bound to the polymer backbone. The number of DTX molecules was determined up to 14 to achieve an optimal release rate, based upon the authors' own pharmacokinetic model using known patient data. Efficacy and toxicity of the formulation was then tested in animals. When administered three times at 4-day intervals, the maximum tolerated doses of NC-6301 and native DTX were 50 and 10 mg/kg, respectively, in nude mice. Tissue distribution studies of NC-6301 in mice at 50 mg/kg revealed prolonged release of free DTX in the tumor for at least 120 hours, thus supporting its effectiveness. Furthermore, in cynomolgus monkeys, NC-6301 at 6 mg/kg three times at 2-week intervals showed marginal toxicity, whereas native DTX, at 3 mg/kg with the same schedule, induced significant decrease of food consumption and neutrophil count. NC-6301 at 50 mg/kg in mice also regressed a xenografted tumor of MDA-MB-231 human breast cancer. Native DTX, on the other hand, produced only transient and slight regression of the same tumor xenograft. NC-6301 also significantly inhibited growth of OCUM-2MLN human scirrhous gastric carcinoma in an orthotopic mouse

The method evaluates protein-protein interfaces in terms of complementarities for hydrophobicity, electrostatic potential and shape on the protein surfaces, and chooses the most probable biological interfaces among all possible contacts in the crystal. The method uses a discriminator named as “COMP”, which is a linear combination of the complementarities for the above three surface features and does not correlate with the contact area. The discrimination of homo-dimer interfaces from symmetry-related crystal-packing contacts based on the COMP value achieved the modest success rate. Subsequent detailed review of the discrimination results raised the success rate to about 88.8%. In addition, our discrimination method yielded some clues for understanding the interaction patterns in several examples in the PDB. Thus, the COMP discriminator can also be used as an indicator of the “biological-ness” of protein-protein interfaces.Keywords: protein-protein interaction, complementarity analysis, homo-dimer interface, crystal-packing contact, biological interfaces

    To share healthcare information and to promote cooperation among healthcare providers and customers (patients) under computerized network environment, a non-profit organization (NPO), named as OCHIS, was established at Osaka, Japan in 2003. Since security and confidentiality issues on the Internet have been major concerns in the OCHIS, the system has been based on healthcare public key infrastructure (HPKI), and found that there remained problems to be solved technically and operationally. An experimental study was conducted to elucidate the central and the local function in terms of a registration authority and a time stamp authority by contracting with the Ministry of Economics and Trading Industries in 2003. This paper describes the experimental design with NPO and the results of the study concerning message security and HPKI. The developed system has been operated practically in Osaka urban area.

    Full Text Available Macro-analysis and East-West encounter are shown through consideration of objective yet subjective constructed concepts for the international system and international economy in the 21st century. Three paradigms are considered, namely the 21st century as the ‘Pacific Century’, as ‘China’s Century’ and as the ‘Asian Century’. Overlaps are shown between these three paradigms, as also developments in time, and gradually shift in geographical location. The ‘Pacific Century’, and its associated Rimspeak, was the paradigm emerging in the late 1970s, knitting together America’s West Coast and the Japanese economy. By the late 1980s this was already shifting to talk of the 21st century likely to be an ‘Asian Century’ model, mark-1, based on the Pacific Asia dynamism shown by the ‘Asian Tigers’ and Japan. However, the Asian financial crash of 1997-8, and the economic downturn in Japan, meant that such an ‘Asian Century’ seemed premature as the 21st century arrived. Instead, it was China’s economic growth that seemed most evident, and with it the concept of the 21st century as ‘China’s Century’. However, in turn that has already been modified during the first decade of the century by India’s arrival as a rapidly growing economy. Consequently the 21st century as ‘China’s Century’ and as ‘India’s Century’ has been combined into talk of an ‘Asian Century’, mark-2.

    Full Text Available Since 1966, approximately 1 000 veterinarians graduate each year from 16 veterinary schools in Japan. According to reports submitted by veterinarians to the Ministry of Agriculture, Forestry and Fisheries in January 2007, there were over 35 818 veterinarians in Japan at the end of 2006. Of this total, 13 202 (36.8% were engaged in companion animal practice, 9 112 (25.4% were civil servants and 4 180 (11.7% were engaged in food animal practice. The total number of veterinarians has increased gradually over the past 40 years. Recently, the number of veterinarians engaged in companion animal practice has increased while the number of veterinarians engaged in food animal practice is declining. These trends reflect the change in demand for veterinarians in food and companion animal practice, resulting mainly from changes in the number of food animals and companion animals in recent years. The number of veterinarians in the public sector has decreased gradually due to the administrative reforms of recent years.

    Objectives The use of maternal and child health-related information is an issue faced by the "Healthy parents and children 21" campaign, a national campaign to improve the health standards of mothers and children in Japan. This study described the current situation and issues faced by municipalities across Japan that use this information.Methods Data across municipalities selected for the current survey of promoting the "Healthy parents and children 21" campaign in 2013 were analyzed in this study. First, we chose prefectures where collected and analyzed maternal and child health-related information was provided by the municipalities. Then, we divided the municipalities according to those prefectures where the municipalities regularly reported the maternal and child health-related information and those that did not report it regularly. Finally, the characteristics about maternal and child health in those municipalities were investigated.Results Of the 47 prefectures analyzed, 35 prefectures (74.5%) collected and analyzed maternal and child health-related information provided by the municipalities. The 35 prefectures included 1,242 municipalities, of which 700 (56.4%) regularly reported maternal and child health-related information, and 542 (43.6%) did not report it regularly. The proportion of municipalities, where information about smoking during pregnancy, immunization, or low birth weight in infants was positively used, was significantly lower among municipalities that did not regularly report maternal and child health-related information than among those that regularly reported it (P<0.001). The proportion of municipalities that coordinated projects on prevention of child abuse or low birth weight in infants with the prefectures was significantly lower among municipalities that did not regularly report maternal and child health-related information than among those that regularly reported it.Conclusion Among municipalities that did not regularly report

    THE FIRST EUROPEANS to discover Japan were Portuguese traders who arrived in 1542. Fifteen years later, the Portuguese Jesuit priest and surgeon Luis De Almeida (1525-1583) founded the first Western hospital in Japan, for the care of lepers, syphilitics, and orphans. Because the hospital had a negative influence on the spread of Christianity, the Jesuits closed it in 1586. During the Tokugawa Shogunate (1600-1868), when Japan was secluded from the rest of the world, the only foreign physicians allowed to enter Japan were those employed by the Dutch factory at Dejima in Nagasaki. Only four of those physicians left behind seeds for the foundation of Western medicine in Japan, namely Caspar Schambergen, who founded a Japanese school of surgery in 1650; Engelbert Kämpfer, who visited Japan in 1691 to 1692; Carl Peter Thunberg, who botanically explored Japan in 1775 to 1776; and Philipp Franz Balthasar von Siebold, who practiced medicine in Nagasaki in 1823 to 1829 and 1859 to 1861. On the whole, Western medicine and surgery never established a real foothold in Japan until the fall of the shogunate and the restoration of the emperor in 1868.

    2015-01-01

    Blood components and plasma derivatives are two of the most useful tools in modern medicine. When the Portuguese opened the maritime routes to the Far East in the 16th century. Western medicine traveled to Japan on the trading vessels that carried physicians and barber-surgeons to care for the body and Christian missionaries to care for the soul. Skilled interpreters such as Kōgyū Yoshio translated and studied Dutch editions of early medical books, like Lorenz Heister's "Chirurgie" (Nürnberg, 1719), that illustrate the concept of transfusion. The oldest description of transfusion originating in Japan is a handwritten manuscript entitled "Bansui Sensi Chojutsu Shomoku" by Masamichi Nishijima, a student of Bansui Otsuki. It is a list of Otsuki's translated works. He described book names and chapter names in the manuscript, and when he finished translation of a chapter, he marked a circle on the chapter name. The transfusion chapter had a circle. That dates the earliest writing on transfusion in Japanese to 1804, shortly after the death of Kōgyū. Unfortunately, the manuscript translation no longer exists. In 1814, Shunzō Yoshio, grandson of Kōgyū, and in 1820, Tokki Koshimura, translated the figure legends of "Chirurgie." Soon afterwards, after the first report of transfusion from human-to-human by James Blundell in London in 1818, Western medical books published on the subject began to arrive. The works of Christoph Wilhelm Hufeland, Georg Friedrich Most and Carl Canstatt all mentioning transfusion, albeit without details, were translated by Kōan Ogata and Shinryō Tsuboi. During the Edo period, Japan was a closed country; only open to the Dutch through a tiny island in Nagasaki. But Japanese doctors in the Edo period learned about blood transfusion through Dutch-translated versions of Western medical Books. Transfusion began being practiced in Japan in 1919, almost exactly 100 years after the concept was introduced

    While the prevalence of sudden infant death syndrome (SIDS) has decreased worldwide, this decline has plateaued recently. Strategies are needed to resume the constant decrease of SIDS in Japan. A prospective electrocardiographic screening program for infants was performed between July 2010 and March 2011. Parents of 4319 infants were asked about environmental factors related to SIDS through questionnaires at a one-month medical checkup and one year. Parental awareness of prone position, smoke exposure, and breast feeding as environmental factors were 81.4 %, 69.0 %, and 47.8 %, respectively. The prevalence of laying infants exclusively in a supine position was 96.7 %. At the one-month medical checkup, smoking prevalence was 41.7 % in fathers and 2.1 % in mothers. Maternal smoking prevalence was significantly increased at one year after (p Japan. Smoking cessation programs should be further implemented for parents to decrease risks of SIDS in Japan. What is Known: • The prevalence of sudden infant death syndrome (SIDS) has decreased worldwide, however, this decline has plateaued recently. What is New: • Most infants were laid sleeping in the supine position (96.7 %) and were fed breast milk or a mix of expressed milk and formula (92.7 %), and 2.1 % of mothers smoked at the one-month medical checkup. • Maternal smoking prevalence significantly increased from the one-month medical checkup to one year later, and smoking mothers were more likely to feed infants by formula rather than breast milk. • Independent risk factors for new or continued maternal smoking habits included younger maternal age, maternal smoking habits at one month, and paternal smoking habits one year later.

  14. Temporal Changes in Post-Infectious Glomerulonephritis in Japan (1976-2009.

    Full Text Available The incidence of post-infectious glomerulonephritis (PIGN in developed countries has decreased over the last 50 years. Here we identified the trends of the incidence of PIGN in Japan during the past four decades.We explored the frequency, clinicopathological findings, and prognosis of PIGN based on 6,369 cases from the Renal Biopsy Database of our institute in the Kanto region of Japan, diagnosed histologically from 1976 to 2009.The numbers of PIGN cases were 131 (2.1% in total, and 2.4%, 1.1%, 2.6% and 2.1% identified in the 1970s, 1980s, 1990s, and 2000s, respectively. Acute glomerulonephritis (AGN, including post-streptococcal glomerulonephritis (PSGN, accounted for almost all of the PIGN cases in the 1970s, but decreased to approx. 40%-50% since the 1990s. In the 1990s, Staphylococcus aureus infection-related nephritis (SARN showed a rapid increase in rate, reaching 30%. The incidence of hepatitis C virus infection-associated GN (HCVGN has increased since the 1990s. The average age at onset rose from 33 to 51 years over the study period. These transitions can be summarized as increases in SARN and HCVGN and decreases in PSGN and other types of AGN, since SARN and HCVGN have older onsets compared to PSGN and other AGN types. The clinicopathological features were marked for each PIGN. Regarding the prognosis, the renal death rates of both the SARN and HCVGN groups were significantly higher than those of other PIGN.Based on our analysis of the Renal Biopsy Database, the incidence of PIGN in Japan reached its peak in the 1990s. The temporal changes in the incidence of PIGN reflected the trends in infectious diseases of each decade and the continual aging of the population, with a related higher susceptibility to infections.

    2008-09-01

    Full Text Available A 76-year-old Japanese man was admitted to Kosei-Nenkin Hospital (Osaka, Japan in November 2006; his chief complaint was a 10-kg loss in body weight over 3 months prior to admission. Abdominal computed tomography (CT and dynamic magnetic resonance imaging (MRI showed three masses in the retroperitoneum. The patient subsequently underwent surgery. The final histopathological diagnosis of tumors 1 and 2 was malignant fibrous histiocytoma of the retroperitoneum, and tumor 3 was a well-differentiated liposarcoma. By the presence of the liposarcoma, tumor 1 and 2 were thought to be the dedifferentiated areas of liposarcomas. At the age of 16, the patient had been exposed to radiation from the atomic bomb at Hiroshima towards the end of the Second World War. We postulate that in this case, radiation from the atomic bomb may have played an important role in the development of the sarcomas.

    Full Text Available Abstract Background At present, six accessible sequences of 16S rDNA from Taylorella equigenitalis (T. equigenitalis are available, whose sequence differences occur at a few nucleotide positions. Thus it is important to determine these sequences from additional strains in other countries, if possible, in order to clarify any anomalies regarding 16S rDNA sequence heterogeneity. Here, we clone and sequence the approximate full-length 16S rDNA from additional strains of T. equigenitalis isolated in Japan, Australia and France and compare these sequences to the existing published sequences. Results Clarification of any anomalies regarding 16S rDNA sequence heterogeneity of T. equigenitalis was carried out. When cloning, sequencing and comparison of the approximate full-length 16S rDNA from 17 strains of T. equigenitalis isolated in Japan, Australia and France, nucleotide sequence differences were demonstrated at the six loci in the 1,469 nucleotide sequence. Moreover, 12 polymorphic sites occurred among 23 sequences of the 16S rDNA, including the six reference sequences. Conclusion High sequence similarity (99.5% or more was observed throughout, except from nucleotide positions 138 to 501 where substitutions and deletions were noted.

    1993-01-01

    In many areas, the word most often used to describe Japanese policy is open-quotes enigma.close quotes In some ways, Japan's record on environmental policy also has elements of mystery and contradiction. On the one hand, Japan's history and culture often are associated with a reverence for nature. Indeed, Japan does lead the world in certain environmental areas, such as reduction of conventional air pollutants and compensation of air pollution victims. On the other hand, Japan has been widely criticized for its poor record in preserving its domestic environment, contribution to tropical deforestation, and unwillingness to protect endangered species. Today, the international community clamors for Japan to take its share of responsibility, as an economic superpower, for the global environment. To secure its place in world affairs, Japan slowly has begun to respond to this pressure on issues ranging from ivory importation to reduction of CFC emissions. There is some hope that the government's particular willingness to address global warming may be a sign of significant changes to come in Japanese environmental policy. However, international pressure remains on the many environmental issues Japan has yet to resolve, including tropical deforestation and financing of Third World development projects that harm the environment. Japan's environmental policy is most effective when government and industry cooperate to find technical solutions to environmental problems. Although in recent years Japan's energy consumption has risen sharply, the Japanese have developed numerous technologies to reduce pollution and increase economic growth by improving energy efficiency. It is in these technologies that Japan has made the greatest strides and has the most to offer the global environment

    To develop a multivariable prognostic model for the risk of preterm delivery in women with multiple pregnancy that includes cervical length measurement at 16 to 21 weeks' gestation and other variables. We used data from a previous randomized trial. We assessed the association between maternal and pregnancy characteristics including cervical length measurement at 16 to 21 weeks' gestation and time to delivery using multivariable Cox regression modelling. Performance of the final model was assessed for the outcomes of preterm and very preterm delivery using calibration and discrimination measures. We studied 507 women, of whom 270 (53%) delivered models for preterm and very preterm delivery had a c-index of 0.68 (95% CI 0.63 to 0.72) and 0.68 (95% CI 0.62 to 0.75), respectively, and showed good calibration. In women with a multiple pregnancy, the risk of preterm delivery can be assessed with a multivariable model incorporating cervical length and other predictors.

  1. Japan`s civil use of foreign military plutonium

    Energy Technology Data Exchange (ETDEWEB)

    Suzuki, A. [Tokyo Univ. (Japan). Dept. of Quantum Engineering and Systems Sciences

    1995-12-31

    This paper is intended to propose one of the MOX options of international cooperation for safer and more secured management of excess military plutonium. The proposal was made with special reference to the Japanese public`s view. Owing to the domestic plutonium shortage anticipated soon after the 200 in Japan, some specific reactors will be available to get rid of foreign excess weapon plutonium. According to the Japan AEC`s new long-term programme, the shortage will be approximately 0.5 tonne of plutonium per annum, which is a sort of the least amount that Japan can buy from a certain external source. With international requests for a more positive Japanese contribution, however, the amount of Japanese purchase would be increased. It follows from the preliminary estimate shown in this paper that roughly 2 tonnes of plutonium can be burned annually in the reactors without any major modifications concerning safe reactor operation.

    Tick-borne diseases are often encountered in canine clinical practice. In the present study, a molecular epidemiological survey of dogs in Japan was conducted to understand the prevalence and geographical distribution of Babesia spp., Hepatozoon spp., Ehrlichia spp. and Anaplasma spp. Pathogen-derived DNA in blood samples obtained from 722 dogs with a history of exposure to ticks and/or fleas was examined by PCR. The prevalence of Babesia gibsoni, Babesia odocoilei-like species, Hepatozoon canis and Ehrlichia spp./Anaplasma spp. was 2.4% (16/722), 0.1% (1/722), 2.5% (18/722) and 1.5% (11/722), respectively. While B. gibsoni and Ehrlichia spp./Anaplasma spp. were detected in the western part of Japan, H. canis was detected in Tohoku area in addition to western and central parts of Japan. PMID:25947226

    Environmental pollution by PCDD/Fs has arisen exclusively from human activities, and for example, they are inadvertently produced from various combustion sources and manufacturing processes, such as municipal solid waste incineration steel production processes and chemical production processes. In Japan, it is well known that the environmental pollution has close relation to agricultural operation, that is, some PCDD/Fs are contained as impurities in a kind of pesticide. The Tone River is the largest basin area (about 16,900 km{sup 2}) in Japan, and after the Shinano River, is the second longest river (about 322 km). The river has many tributaries (about 800 rivers), and the rivers taking the Kokai River, the Kinu River, the Edo River, and the Watarase River as objects of the present study are also representative tributaries. Since the Tone River basin corresponding to about 4.5% of the total area of Japan leads about twelve million population corresponding to about 10% of the gross population in Japan, it plays an important part in a supply of water for human activities. Not only some residential zones near Tokyo and industrial zones but also representative agricultural zones in Japan expand in the basin expands, and especially the lower basin leads a leading granary. The objective of our effort is to investigate the levels of PCDD/Fs and PCBs in surface sediment and water samples from the Tone River and some related tributaries, and to assess their distribution and origin using congener-specific characterization approach.

    I am to report on some aspects of industrial lasers in Japan. Mostly centering on the market. In Japan, the history of laser developnent is rather profound. And long. Ever since the first invention of the laser in this country in 1960. This is partly because of the fact that in Japan the spectroscopic studies of the ruby was very popular in the late 1950's. Ever since niost of the work has been done in the research laboratories of the industry, not in the universities or not in the governmental laboratories. And since that time our first activity was mainly centering on the basic research, but after that time we have the evolution of the technology. One of the features in Japan is that the activity of developement and research of laser technology from the very basic phase up to the present commercialization has been done by the same group of people, including ine. We had a national project which ended about six years ago which was sponsored by MITI. MITI is Ministry of International Trade and Industry in Japan. And because of this national project, the effect of this project had a very enlightening effect in Japan. And after that our Japanese laser market became very flourishing.

    Full Text Available The article is devoted to the development of the modern politics of identity construction in Japan, which actively refers to the practice of designing self-image in international relations. This trend dates back to the 19th century, when there was the end of Sakoku (Japan’s policy of isolation. It is now possible to talk about the institutionalization of the identity construction policy to organized structures and regulations. Enhanced efforts in the field of Japanese traditional and popular culture, education and creative content has led to a number of institutions appearance (like Japan Foundation Fund, Japan Creative Agency, Japan Culture Fund, Agency for Cultural Affairs, Cool Japan Fund, Japan brand Fund and changing idea about the role of culture in foreign policy realization (it is fixed the documents of the Japanese Ministry of Foreign Affairs, the Ministry of Land, Infrastructure, Transport and Tourism, the Ministry of Education, Culture, Sports, Science and Technology, the Ministry of Economy, Trade and Industry, as well as a number of projects (Cool Japan, Visit Japan, Japan Culture Power, Japan Manga Awards, Kawaii Ambassadors, Cosplay International Fest and etc.. These efforts are aimed at forming Japan identity abroad to solve a number of foreign policy challenges of the future and the development of economic cooperation. The Japanese government nearest plans is to increase funding in order to create a positive image of Japan in the region of East Asia. All of these allows us to speak about the policy of the Japanese construction of identity as an institutionalized process in which there was clearance of organizations and regulatory activities.

    Placozoans, flat free-living marine invertebrates, possess an extremely simple bauplan lacking neurons and muscle cells and represent one of the earliest-branching metazoan phyla. They are widely distributed from temperate to tropical oceans. Based on mitochondrial 16S rRNA sequences, 19 haplotypes forming seven distinct clades have been reported in placozoans to date. In Japan, placozoans have been found at nine locations, but 16S genotyping has been performed at only two of these locations. Here, we propose a new processing protocol, "ethanol-treated substrate sampling," for collecting placozoans from natural environments. We also report the collection of placozoans from three new locations, the islands of Shikine-jima, Chichi-jima, and Haha-jima, and we present the distribution of the 16S haplotypes of placozoans in Japan. Multiple surveys conducted at multiple locations yielded five haplotypes that were not reported previously, revealing high genetic diversity in Japan, especially at Shimoda and Shikine-jima Island. The observed geographic distribution patterns were different among haplotypes; some were widely distributed, while others were sampled only from a single location. However, samplings conducted on different dates at the same sites yielded different haplotypes, suggesting that placozoans of a given haplotype do not inhabit the same site constantly throughout the year. Continued sampling efforts conducted during all seasons at multiple locations worldwide and the development of molecular markers within the haplotypes are needed to reveal the geographic distribution pattern and dispersal history of placozoans in greater detail.

    "Ikigai" is culturally defined in the society of Japan as a comprehensive concept describing subjective well-being. It is considered to be related to life-satisfaction, self-esteem, morale, happiness as well as evaluation towards meaning of one's life. Although previous studies examined factors associated with Ikigai with smaller samples, consistent results have not been obtained, especially from the viewpoint of gender differences. Identification of gender-specific factors related with Ikigai among the elderly, may be of value to enhance subjective well-being. Self-administered questionnaires were distributed among 4,737 randomly selected members of the Silver Human Resources Centre (SHRC), a public temporary employment agency for seniors, in Osaka, Japan. This represents about 10% of all registered members (n = 41,593) in the 38 SHRC centres in Osaka. A total of 4,376 subjects (male: 2,913; female: 1,463) provided a satisfactory response to the questionnaire (response rate: 92%). The status whether they have "Ikigai" or not was evaluated by self-anchoring scale ranging from 0 to 5 (0 = lowest rate and 5 = highest rate of having "Ikigai"). Also, self-rated life-change score through work (-3 to 3) was evaluated by three items, i.e.) changes in (1) the number of friends through work, (2) social interests and (3) the quantity of conversation with others (1 = increase, 0 = no change, and -1 = decrease). The factors associated with "Ikigai" for total subjects were the number of rooms in one's residence, annual income, healthy life style score (Breslow), the number of working days through SHRC, satisfaction with one's life history and life-change sore through work. The multivariable odds ratio (95% CI) of having "Ikigai" was 1.9 (1.1-3.3) for persons with no change in life thorough work compared with subjects with a score of Ikigai" were the number of rooms in their residence, annual income, the number of working days through SHRC, subjective assessment of health

    Full Text Available Kotaro Saga, Yasufumi Kaneda Division of Gene Therapy Science, Graduate School of Medicine, Osaka University, Osaka, Japan Abstract: Many drugs have been developed and optimized for the treatment of cancer; however, it is difficult to completely cure cancer with anticancer drugs alone. Therefore, the development of new therapeutic technologies, in addition to new anticancer drugs, is necessary for more effective oncotherapy. Oncolytic viruses are one potential new anticancer strategy. Various oncolytic viruses have been developed for safe and effective oncotherapy. Recently, Sendai virus-based oncotherapy has been reported by several groups, and attention has been drawn to its unique anticancer mechanisms, which are different from those of the conventional oncolytic viruses that kill cancer cells by cancer cell-selective replication. Here, we introduce Sendai virus-based virotherapy and its anticancer mechanisms. Keywords: HVJ-E, cancer therapy, apoptosis, necroptosis, anticancer immunity 

  17. Generic antibiotics in Japan.

    2012-08-01

    Generic drugs have been used extensively in many developed countries, although their use in Japan has been limited. Generic drugs reduce drug expenses and thereby national medical expenditure. Because generic drugs provide advantages for both public administration and consumers, it is expected that they will be more widely used in the future. However, the diffusion rate of generic drugs in Japan is quite low compared with that of other developed countries. An investigation on generic drugs conducted by the Ministry of Health, Labour and Welfare in Japan revealed that 17.2 % of doctors and 37.2 % of patients had not used generic drugs. The major reasons for this low use rate included distrust of off-patent products and lower drug price margin compared with the brand name drug. The generic drugs available in the market include external drugs such as wet packs, antihypertensive agents, analgesics, anticancer drugs, and antibiotics. Among them, antibiotics are frequently used in cases of acute infectious diseases. When the treatment of these infections is delayed, the infection might be aggravated rapidly. The pharmacokinetics-pharmacodynamics (PK-PD) theory has been adopted in recent chemotherapy, and in many cases, the most appropriate dosage and administration of antibiotics are determined for individual patients considering renal function; high-dosage antibiotics are used preferably for a short duration. Therefore, a highly detailed antimicrobial agent is necessary. However, some of the generic antibiotics have less antibacterial potency or solubility than the brand name products. We showed that the potency of the generic products of vancomycin and teicoplanin is lower than that of the branded drugs by 14.6 % and 17.3 %, respectively. Furthermore, we confirmed that a generic meropenem drug for injection required about 82 s to solubilize in saline, whereas the brand product required only about 21 s. It was thought that the cause may be the difference in size of bulk

    Trisomy 21 results in gene-dosage imbalance during embryogenesis and throughout life, ultimately causing multiple anomalies that contribute to the clinical manifestations of Down syndrome. Down syndrome is associated with manifestations of variable severity (e.g., heart anomalies, reduced growth, dental anomalies, shortened life-span). Craniofacial dysmorphology and cognitive dysfunction are consistently observed in all people with Down syndrome. Mouse models are useful for studying the effects of gene-dosage imbalance on development. We investigated quantitative changes in the skull and brain of the Dp(16)1Yey Down syndrome mouse model and compared these mice to Ts65Dn and Ts1Cje mouse models. Three-dimensional micro-computed tomography images of Dp(16)1Yey and euploid mouse crania were morphometrically evaluated. Cerebellar cross-sectional area, Purkinje cell linear density, and granule cell density were evaluated relative to euploid littermates. Skulls of Dp(16)1Yey and Ts65Dn mice displayed similar changes in craniofacial morphology relative to their respective euploid littermates. Trisomy-based differences in brain morphology were also similar in Dp(16)1Yey and Ts65Dn mice. These results validate examination of the genetic basis for craniofacial and brain phenotypes in Dp(16)1Yey mice and suggest that they, like Ts65Dn mice, are valuable tools for modeling the effects of trisomy 21 on development. © 2014 Wiley Periodicals, Inc.

    From January 1980 through April 1990, a total of 317 patients with an oral cancer were treated with radiation therapy at Department of Radiology, Osaka University Hospital. Twenty-seven (8.5%) of these 317 patients had other primary cancers. For statistical purposes, the expected number of other primary cancers was estimated by multiplying the age-sex specific incidence rates among Osaka residents with the Person-year at risk figures, based on the Osaka Prefectural Cancer Registry. The observed/expected [0/E] ratios were 16.00 (p<0.01) for the esophagus and 28.42 (p<0.01) for the oropharynx. The present study suggested the necessity of following up oral cancer patients, especially those who have had carcinoma of the mouth floor, in order to enable the early diagnosis of upper digestive tract cancer.

    The Mw 9.1 Tohoku-oki earthquake caused strong shakings of super high rise and high rise buildings constructed on deep sedimentary basins in Japan. Many people felt difficulty in moving inside the high rise buildings even on the Osaka basin located at distances as far as 800 km from the epicentral area. Several empirical equations are proposed to estimate the peak ground motions and absolute acceleration response spectra applicable mainly within 300 to 500km from the source area. On the other hand, Japan Meteorological Agency has recently proposed four classes of absolute velocity response spectra as suitable indices to qualitatively describe the intensity of long-period ground motions based on the observed earthquake records, human experiences, and actual damages that occurred in the high rise and super high rise buildings. The empirical prediction equations have been used in disaster mitigation planning as well as earthquake early warning. In this study, we discuss the results of our preliminary analysis on attenuation relation of absolute velocity response spectra calculated from the observed strong motion records including those from the Mw 9.1 Tohoku-oki earthquake using simple regression models with various model parameters. We used earthquakes, having Mw 6.5 or greater, and focal depths shallower than 50km, which occurred in and around Japanese archipelago. We selected those earthquakes for which the good quality records are available over 50 observation sites combined from K-NET and KiK-net. After a visual inspection on approximately 21,000 three component records from 36 earthquakes, we used about 15,000 good quality records in the period range of 1 to 10s within the hypocentral distance (R) of 800km. We performed regression analyses assuming the following five regression models. (1) log10Y (T) = c+ aMw - log10R - bR (2) log10Y (T) = c+ aMw - log10R - bR +gS (3) log10Y (T) = c+ aMw - log10R - bR + hD (4) log10Y (T) = c+ aMw - log10R - bR +gS +hD (5) log10Y

    Japan has the most CT and MRI scanners per unit population in the world, and as these technologies spread, their geographic distribution is becoming equalized. In contrast, the number of radiologists per unit population in Japan is the lowest among OECD countries and their geographic distribution is unknown. Likewise, little is known about the use of teleradiology, which can compensate for the uneven distribution of radiologists. Based on the Survey of Physicians, Dentists and Pharmacists and the Static Survey of Medical Institutions by the Ministry of Health, Labour and Welfare, a dataset of radiologists and CT and MRI utilizations in each of Japan's 1811 municipalities was created. The inter-municipality equity of the number of radiologists was evaluated using Gini coefficient. Logistic regression analysis, based on Static Survey data, was performed to evaluate the association between hospital location and teleradiology use. Between 2006 and 2012 the number of radiologists increased by 21.7%, but the Gini coefficient remained unchanged. The number of radiologists per 1,000 CT (MRI) utilizations decreased by 17.9% (1.0%); the number was highest in metropolis and lowest in town/village and the disparity has widened from 1.9 to 2.2 (1.6 to 2.0) times. The number of hospitals and clinics using teleradiology has increased (by 69.6% and 18.1%, respectively). Hospitals located in towns/villages (odds ratio 1.61; 95% confidence interval 1.26-2.07) were more likely to use teleradiology than those in metropolises. Contrary to the CT and MRI distributions, radiologist distribution has not been evened out by the increase in their number; in other words, the distribution of radiologists was not affected by market-derived spatial competition force. As a consequence, the gap of the radiologist shortage between urban and rural areas is increasing. Teleradiology, which is one way to ameliorate this gap, should be encouraged.

    With domestic application of the IAEA new measures (program 93+2) for strengthening the effectiveness and improving the efficiency of the safeguards system, the Nuclear Regulation Laws was amended for implementation of the new measures based upon the Additional Protocol, and also the new Designated Organization System was introduced to the SSAC (States' System of Accounting for and Control of Nuclear Materials) for safeguards implementation in Japan since beginning of January 2000. On the basis of accumulated experiences of the state safeguards implementation for more than 20 years and then established standardization of the inspection procedures, the Japan's Government is able to utilize the expertise of private organizations for the safeguards implementation. Any capable organizations can be designated by the Government as the Designated Organization for all or a part of safeguards implementations on behalf of the Government. According to the amended Law, the Prime Minister can make the Designated Organization implement safeguards implementations that are defined firstly as safeguards inspections which can be done along the Government instructions without any discussions and decisions, secondarily as destructive analysis of safeguards samples, and thirdly as technical research on advanced safeguards measures. The amendment of the Law was approved by the National Diet on June 9th 1999 and entered into force on December 16th 1999. The Additional Protocol also entered into force in Japan at the same time. The NMCC (Nuclear Material Control Center) was designated as the Organization on December 27th 1999 and started the safeguards implementation in January 7th 2000. In order to prepare for the Designated Organization, the NMCC rearranged the organizational system and kept capable human resources enough for the safeguards implementations. Also the NMCC carried out many programs of education and training for the inspectors. Furthermore, manuals and criteria for the

Recently, image processing with the homology method has been proposed. In this study, we used the homology method and computed tomography images to quantify emphysema.Methods: This study included 112 patients who had undergone computed tomography and pulmonary function test. Low-attenuation lung regions were evaluated by the homology method, and homology-based emphysema quantification (b0, b1, nb0, nb1, and R was performed. For comparison, the percentage of low-attenuation lung area (LAA% was also obtained. Relationships between emphysema quantification and pulmonary function test results were evaluated by Pearson’s correlation coefficients. In addition to the correlation, the patients were divided into the following three groups based on guidelines of the Global initiative for chronic Obstructive Lung Disease: Group A, nonsmokers; Group B, smokers without COPD, mild COPD, and moderate COPD; Group C, severe COPD and very severe COPD. The homology-based emphysema quantification and LAA% were compared among these groups.Results: For forced expiratory volume in 1 second/forced vital capacity, the correlation coefficients were as follows: LAA%, -0.603; b0, -0.460; b1, -0.500; nb0, -0.449; nb1, -0.524; and R, -0.574. For forced expiratory volume in 1 second, the coefficients were as follows: LAA%, -0.461; b0, -0.173; b1, -0.314; nb0, -0.191; nb1, -0.329; and R, -0.409. Between Groups A and B, difference in nb0 was significant (P-value = 0.00858, and those in the other types of quantification were not significant.Conclusion: Feasibility of the

    Number of epilepsy patient in Japan officially surveyed by our government in 2008 is 219,000, which is only 0.17% of the total population and less than one third of the prevalence rate reported in Western countries. Number of epilepsy surgery per year in Japan is also low and less than half of other countries such as US, UK and Korea. These numbers may suggest that epilepsy care in Japan is not sufficient to cover all hidden medical needs of people with epilepsy at present. To solve this issue, our research group funded by the government have started to build an epilepsy care network among primary care physicians, secondary care neurology specialists and tertiary care epilepsy centers by utilizing a web site: Epilepsy Care Network-Japan (http://www.ecn-japan.com/) from July 2012. We are also proposing an epilepsy care algorithm suitable for our complex medical community consisted with various neurology specialists such as pediatric and adult neurologists, neurosurgeons and psychiatrists. Building Epilepsy Care Network in Japan may facilitate better medical and social support for people with epilepsy in Japan.

    1984-01-01

    A summary of nuclear energy in Japan is presented. Nuclear energy provides 17% of Japan's electricity but could provide much more. 25 more reactors (to add to the existing 27) are planned by 1995. The cooperation between Japanese government and industry and the economic assistance in building new plants means that these are not likely to be cancelled. Public acceptance of new plants has often been obtained by large cash employment inducements. Now, however, there is growing disillusionment when short-term well paid employment building the reactors is followed by unemployment when the reactor is in operation. Also there is a growing opposition to the storage of the nuclear waste. To maintain the growth of its nuclear industry Japan needs to export to provide a steady flow of big orders. (U.K.)

    Coke ovens in Japan have 28 years of service on the average and the supply of coke is foreseen to suffer a shortage at the early years of the 21st century. Furthermore, the existing cokemaking process entails a lot of issues such as an effective use of coal resources, an adverse effect on environment. Thus, the Japan Iron and Steel Federation has launched a 9 year research programme called SCOPE 21 in collaboration with the Center for Coal Utilization, Japan in 1994. The programme pursues the following targets. The use ratio of poor coking coal increases from 20-50% with the improvement of coking property of coal by rapid heating and the increase of bulk density by mixing the briquetted coal. The coking time is reduced by rapid heating to 350 to 400{degree}C at the preheater, coking up to 750-850{degree}C at oven chamber, and reheating up to 1000{degree}C at the upgrading chamber, thus trebling productivity. The environment of coke oven is improved by emission free system and by improving the heating system of coke oven to reduce NOx in oven exhaust gas. After two years of preliminary feasible study the programme has advanced to basic research and to a bench scale test. It is in a stage of the construction of a pilot plant. This report describes the outline of the programme and the results obtained through the basic research and the bench scale plant tests. 2 refs., 17 figs., 5 tabs.

    Zoanthids (Cnidaria, Hexacorallia) of the genus Epizoanthus are often found in association with other marine invertebrates, including gastropods and hermit crabs. However, little information exists on the specificity and nature of these associations due to a lack of investigation into Epizoanthus species diversity, and the taxonomy of Epizoanthus is therefore confused. In this study, analyses of morphological data (tentacle number, polyp size, etc) and molecular data (mitochondrial cytochrome oxidase subunit 1 = COI, 16S ribosomal DNA = 16S rDNA) were used to examine Epizoanthus specimens from Tosa Bay, Kochi, Japan. The Epizoanthus specimens were found on both live gastropods (Gemmula unedo) and hermit crabs (Paguristes palythophilus) inhabiting G. unedo and G. cosmoi shells. While morphological analyses did not show clear differences between examined specimens, both COI and mt 16S rDNA clearly divided the specimens into two groups, one associated only with hermit crabs (= Epizoanthus sp. C), and another associated only with living gastropods (= Epizoanthus sp. S). Unexpectedly, DNA sequences from both groups did not match with two previously reported Epizoanthus species from Japan (E. indicus, E. ramosus), indicating they both may be undescribed species. These results highlight the utility of DNA "barcoding" of unknown zoanthids, and will provide a foundation for re-examinations of Epizoanthus species diversity and specificity, which will be critical in understanding the evolution of these unique marine invertebrates.

    Japan has scarce energy resources and depends on foreign resources for 84% of its energy needs. Therefore, Japan has made efforts to utilize nuclear power as a key energy source since mid-1950's. Today, the nuclear energy produced from 49 nuclear power plants is responsible for about 31% of Japan's total electricity supply. The cumulative amount of spent fuel generated as of March 1995 was about 11,600 Mg U. Japan's policy of spent fuel management is to reprocess spent nuclear fuel and recycle recovered plutonium and uranium as nuclear fuel. The Tokai reprocessing plant continues stable operation keeping the annual treatment capacity or around 90 Mg U. A commercial reprocessing plant is under construction at Rokkasho, northern part of Japan. Although FBR is the principal reactor to use plutonium, LWR will be a major power source for some time and recycling of the fuel in LWRs will be prompted. (author). 3 figs

    Acid deposition survey in Japan has started since 1991 by Japan Environmental Laboratories Association (JELA). The JELA has about 60 monitoring sites for wet deposition including remote, rural and urban area. The measured constituents of wet deposition are; precipitation, pH, electric conductivity, major Anions, and major Cations. From those data, we analyze spatial and temporal variations of wet deposition components in Japan. Among the 60 monitoring sites, 39 sampling sites were selected in this study, which have kept sampling continuously between 2003JFY and 2014JFY. All samples were collected by wet-only samplers. To analyze area characteristics, all the areas were divided into 6 regions; Northern part of Japan (NJ), Facing the Japan Sea (JS), Eastern part of Japan (EJ), Central part of Japan (CJ), Western part of Japan (WJ) and Southern West Islands (SW). NO3- and non-sea-salt-SO42- (nss-SO42-) are major components of rain acidification. Especially, between December and February (winter) the air mass from west affected the temporal variations of those acid components and the concentrations were higher in JS and WJ regions than those in other regions. Japanese ministry of the Environment reported that mixing ratio of NO2 in Japan has been less than 0.04ppm since 1976, and that of SO2 has been less than 0.02ppm since 1978. Their concentrations in Japan have remained flat or slowly decreased recently. However the temporal variations of NO3-/nss-SO42- ratio in winter in JS region were significantly increased on average at 2.2% y-1 from 2003JFY to 2014JFY. The results suggest that long-range transboundary air pollutants increased NO3- concentrations and NO3-/nss-SO42- ratio.

    Compared with the abundant data from Western countries, evidence regarding meat consumption and colorectal cancer is limited in the Japanese population. We evaluated colorectal cancer risk in relation to meat consumption in a population?based prospective cohort study in Japan. Participants were 13 957 men and 16 374 women aged ?35 years in September 1992. Meat intake, assessed with a validated food frequency questionnaire, was controlled for the total energy intake.

    In Japan, the departments of nursing were established by 2004, and graduate school programs for master's degree were established by 2008, in 42 national universities. With these changes, a more academic mission has been pursued, and the need for writing papers in English has increased. To investigate the numbers of papers published in English from the nursing departments of national universities in Japan over the past ten years. The lists of teachers who have nursing licenses in the departments of nursing in the 42 national universities (n=2292) were obtained from the Japan Association of Nursing Programs in Universities. The number of papers published in English by these teachers from 2004 to 2013 was counted using the SCOPUS database. The average number of total papers, in which at least one of the authors was a nursing teacher, and first-authored papers, in which the first author was a nursing teacher, were 211.4 and 69.9 per year, respectively; both increased approximately two-fold during the past ten years. The means and standard deviations of the number of total papers and first-authored papers were 50.3±63.8 (range: 1-382) and 18.3±23.4 (range: 0-147) according to universities, and 1.39±5.84 (range: 0-140) and 0.33±1.28 (range: 0-21) according to teachers, respectively. When journals with the highest number of papers were analyzed, 12 of the top 20 (total papers) and 12 of the top 16 (first-authored papers) were in journals whose editorial offices are in Japan. The number of papers published in English has increased over the past ten years, varied markedly depending on the universities and teachers, and many papers were published in Japanese journals. To our knowledge, this is the first report anywhere to determine the average number of nursing papers "per teacher" in a specific population. Copyright © 2015 Elsevier Ltd. All rights reserved.

  3. Nuclear power development in Japan

    The energy situation in Japan is briefly outlined. Vulnerability in energy structure of the country is shown by a comparison of primary energy supply patterns of Japan and Western countries. Japan's energy policy consists in reducing dependence on oil, promoting efficient use of energy and increasing use of non-fossil fuels. Nuclear power is a core of alternative energy for petroleum because of stable supply of nuclear fuel, low detrimental emissions and less dependence on the fuel. A short historical review of nuclear power development in Japan is presented. Some future issues as development of entire nuclear fuel cycle, social acceptance, reactor safety and nuclear power economics are also discussed. 6 figs. (R.T.)

    In the light of the significance of extremophiles as model organisms to access possible extraterrestiral life, we provide a short review of the systematics of thermophilic Archaea, and introduce our exploratory research of novel thermophilic Archaea from hot springs in Japan. Up to date, we have isolated 162 strains of the thermophilic Archaea from hot springs in Japan by the enrichment method or the most probable number/PCR method, and the 16S rRNA gene sequences were determined to reveal their phylogenetic diversity. The sequence comparison illustrated that the isolates belonged to the orders Sulfolobales (117 isolates) , Thermoproteales (29 isolates), Desulfurococcales (8 isolates) and Thermoplasmatales (8 isolates), and there were six separate lineages representing new genera, and at least seven new species as predicted by the phylogenetic distance to known species. The collection of isolates not only included novel taxa but would give some implication for a necessity to reevaluate the current taxonomy of the thermophilic Archaea.

    To clarify the characteristics of post-travel consultation services in Japan, particularly in the provinces, we analyzed our post-travel patients in the travel clinic of Kurume University Hospital located in Kurume City (a regional hub City in southwestern Japan). Sixty post-travel patients visited our clinic between April 2008 and October 2014 and participated in this study: 55 were Japanese and five were foreign. We summarized and compared the characteristics of the patients after dividing the Japanese participants into long-term travelers (>14 days) and short-term travelers (≤14 days). The foreign travelers were described in a separate analysis. Of the 55 Japanese travelers, the mean age (± standard deviation) was 37.3 ± 16.3 years, and 36 patients (65%) were men. Southeast Asia was the major destination (30/55, 55%), and business was stated as the major reason for travel (16/55, 29%). Post-exposure rabies prophylaxis (16/55, 29%) was the most common purpose for the consultations. There were 34 participants (62%) who were classified as short-term travelers. Fewer of the short-term travelers stated receiving pre-travel consultations compared with long-term travelers (11% vs. 79%, p=0.0002). The five foreign travelers included one dengue fever patient and two malaria patients. Most post-travel Japanese patients visited our clinic were short-term travelers who had not received any pre-travel consultation. One of the most common complaints, post-exposure rabies prophylaxis, could have been avoided to some extent by appropriate pre-travel consultations. The results of this study suggest that pre-travel consultations should therefore be encouraged for both long- and short-term travelers.

    The latest version of the Standard Tables of Food Composition in Japan-2015- comprises the main food composition table (Standard Tables of Food Composition in Japan-2015-[Seventh revised Edition)) and three supplementary books. The supplementary books are Standard Tables of Food Composition in Japan - 2015 - (Seventh Revised Edition) - Amino Acids -, Standard Tables of Food Composition in Japan - 2015 - (Seventh Revised Edition) - Fatty Acids - and Standard Tables of Food Composition in Japan - 2015 - (Seventh Revised Edition) - Available Carbohydrates, Polyols and Organic Acids-. We believe understanding these food composition tables can give greater insight into Japan's gastronomic culture and changes in eating habits. We expect them to play important roles as part of the East Asia food composition tables. Copyright © 2017. Published by Elsevier Ltd.

  7. Japan's electronic packaging technologies

    Tummala, Rao R.; Pecht, Michael

    1995-02-01

    The JTEC panel found Japan to have significant leadership over the United States in the strategic area of electronic packaging. Many technologies and products once considered the 'heart and soul' of U.S. industry have been lost over the past decades to Japan and other Asian countries. The loss of consumer electronics technologies and products is the most notable of these losses, because electronics is the United States' largest employment sector and is critical for growth businesses in consumer products, computers, automobiles, aerospace, and telecommunications. In the past there was a distinction between consumer and industrial product technologies. While Japan concentrated on the consumer market, the United States dominated the industrial sector. No such distinction is anticipated in the future; the consumer-oriented technologies Japan has dominated are expected to characterize both domains. The future of U.S. competitiveness will, therefore, depend on the ability of the United States to rebuild its technological capabilities in the area of portable electronic packaging.

    The aim of this study was to characterize post-procedural intravascular ultrasound (IVUS) findings in the ABSORB Japan trial, specifically stratified by the size of target coronary arteries. Despite overall noninferiority confirmed in recent randomized trials comparing bioresorbable vascular scaffolds (BVS) (Absorb BVS) and cobalt-chromium everolimus-eluting metallic stents (CoCr-EES), higher event rates of Absorb BVS have been reported with suboptimal deployment, especially in small coronary arteries. In the ABSORB Japan trial, 150 patients (2:1 randomization) were scheduled in the IVUS cohort. Small vessel was defined as mean reference lumen diameter strategy, possibly different between polymeric and metallic devices, needs to be established for bioresorbable scaffold technology.

    In 2009, the Japan Anti-Doping Agency (JADA) established the "Sports Pharmacist Accreditation Program" to prevent doping in sports. Since then, anti-doping activities in Japan have been attracting attention. In this study, we investigated research about the current status of doping from 2007 to 2014 in Japan to make anti-doping activities more concrete, and we also discussed future anti-doping activities by pharmacists. In Japan, bodybuilding was the sporting event with the highest number and rate of doping from 2007 to 2014. Many of the positive doping cases were detected for class S1 (anabolic agents), S5 (diuretics and masking agents), and S6 (stimulants). Within class S1, supplements were the main cause of positive doping. Within class S5, medicines prescribed by medical doctors were the main cause of positive doping. Within class S6, non-prescription medicines (e.g., OTC) were the main cause of positive doping. When we looked at the global statistics on doping, many of the positive doping cases were detected for class S1. On comparing the Japanese statistics with the global statistics, the rate of positive doping caused by class S1 was significantly lower, but that caused by classes S5 and S6 was significantly higher in Japan than in the world. In conclusion, pharmacists in Japan should pay attention to class S1, S5, and S6 prohibited substances and to the sport events of bodybuilding. Based on this study, sports pharmacists as well as common pharmacists should suggest new anti-doping activities to prevent doping in the future.

    Like health care systems in other developed countries, Japan's health care system faces significant challenges due to aging of the population and economic stagnation. Advanced medicine (Senshin Iryou) is a unique system of medical care in Japan offering highly technology-driven medical care that is not covered by public health insurance. Advanced medicine has recently developed and expanded as part of health care reform. Will it work? To answer this question, we briefly trace the historical development of advanced medicine and describe the characteristics and current state of advanced medical care in Japan. We then offer our opinions on the future of advanced medicine with careful consideration of its pros and cons. We believe that developing advanced medicine is an attempt to bring health care reform in line rather than the goal of health care reform.

    Physicians often fail to suspect Clostridium difficile infection (CDI) and many microbiology laboratories use suboptimal diagnostic techniques. To estimate the extent of and reasons for incorrect diagnosis of CDI in Japan, we investigated toxigenic C. difficile isolated from all stool culture samples and clinical course. Over a 12-month period in 2010, all stool culture samples (n = 975) submitted from inpatients in a university hospital in Japan were cultured for C. difficile and routine microbiological testing was conducted. In total, 177 C. difficile isolates were recovered, and 127 isolates were toxigenic. Among the toxin-A-positive/toxin-B-positive isolates, 12 were also positive for the binary toxin gene. However, clinically important ribotypes, such as 027 and 078, were not identified. A total of 58 (45.7%) cases with toxigenic C. difficile had unformed stool, and the incidence CDI was 1.6 cases per 10,000 patient-days. Of these 58 cases, 40 were not diagnosed in routine testing due to a lack of clinical suspicion (24.1%, 14/58) or a negative C. difficile toxin assay result (44.8%, 26/58). A stool toxin assay was performed in 54 patients (78.2%, 54/69) who did not have unformed stool. The present study demonstrated that a significant number of CDI cases in Japan might be overlooked or misdiagnosed in clinical practice due to a lack of clinical suspicion and limitations of microbiological testing for CDI in Japan. Providing education to promote awareness of CDI among physicians is important to improve the accuracy of diagnosis in Japan.

    1998-05-01

    The Common Agenda for Cooperation in Global Perspective is a bilateral partnership established in 1993 between the US and Japan to address important global challenges of the 21st century such as global health and human development, including population and HIV/AIDS, global stability, protection of the global environment, and the advancement of science and technology. On the fifth anniversary of the agenda, representatives of the Japan and the US governments, international organizations, and private sectors discussed ways to further promote US-Japan cooperation under the agenda at a meeting held in Tokyo during March 12-13. Participants of the Common Agenda Open Forum also reviewed efforts made by Japan and the US under the agenda to address population and the environment. Forum participants focused upon developing new ideas for future cooperation between the governments, the private sector, and other nations, especially in the areas of health and the environment. The meeting was jointly organized by Japan's Ministry of Foreign Affairs and the US Department of State. Attention was also given during talks to diminishing international assistance budgets worldwide.

    The present study aimed to compare cancer incidence and trends in survival for children diagnosed in Japan and England, using population-based cancer registry data. The analysis was based on 5192 children with cancer (age 0-14 years) from 6 prefectural cancer registries in Japan and 21 295 children diagnosed in England during 1993-2010. Differences in incidence rates between the 2 countries were measured with Poisson regression models. Overall survival was estimated using the Kaplan-Meier method. Incidence rates for Hodgkin lymphoma, renal tumors and Ewing sarcomas in England were more than twice as high as those in Japan. Incidence of germ cell tumors, hepatic tumors, neuroblastoma and acute myeloid leukemia (AML) was higher in Japan than in England. Incidence of all cancers combined decreased in Japan throughout the period 1993 to 2010, which was mainly explained by a decrease in registration of neuroblastoma in infants. For many cancers, 5-year survival improved in both countries. The improvement in survival in chronic myeloid leukemia (CML) was particularly dramatic in both countries. However, 5-year survival remained less than 80% in 2005-2008 in both countries for AML, brain tumors, soft tissue sarcomas, malignant bone tumors and neuroblastoma (age 1-14 years). There were significant differences in incidence of several cancers between countries, suggesting variation in genetic susceptibility and possibly environmental factors. The decrease in incidence for all cancers combined in Japan was related to the cessation of the national screening program for neuroblastoma. The large improvement in survival in CML coincided with the introduction of effective therapy (imatinib). © 2017 The Authors.

    Polychlorinated n-alkanes (PCAs) are group of chemicals manufactured by chlorination of liquid n-paraffin or paraffin wax that contain 30 to 70% chlorine by weight. Large amounts of PCAs are widely used as plasticizers for vinyl chloride, lubricants, paints, and flame retardants and number of other industrial applications. Annual global production of PCAs is approximately 300 kilo tones, with a majority having medium-carbon-chain (C14-C19) length. According to the investigation made by Kagaku Kogyo Nippon-Sha, the annual consumption of PCAs in Japan was about 83,000 tons in between 1986-2001. Short-carbon-chain (C10-C13) has been placed on the Priority Substance List under Canadian Environmental Protection Act and on the Environmental Protection Agency Toxic Release Inventory in the USA due to its potential to act as tumor promoters in mammals. Data on environment levels of PCAs is meager, nevertheless, PCAs have been measured at relatively high concentrations in biota from Sweden, biota, sediment from Canada and marine biota and human milk from the Canadian Arctic. In our earlier study, we reported concentrations of short-chain PCAs from sewage treatment plant (STP) collected from Tama River, Tokyo and river water and sediment from Tokyo and Osaka. STP influent water contained greater shortchain PCAs concentrations than STP effluent. In addition, some river water and sediment samples contained detectable concentrations of short-chain PCAs, which was similar to other industrial countries. However, there is no study conducted to explore the contamination profiles of short-chain PCAs in human foodstuff samples. In the present study, we analyzed eleven foodstuff samples that were purchased from various supermarkets in order to know the short-chain PCAs concentrations in the foodstuff and possible human total daily intake (TDI) amounts.

    1990-01-01

    The Nuclear Safety Commission made a careful examination regarding the merger between Toshiba Corporation and Japan Atomic Energy Operation Co., Ltd., (an issue submitted on August 16, 1989, for deliberation), and submitted a report to the prime minister. A study was carried out to determine whether the technical expertise possessed by Japan Atomic Energy Operation Co. would taken over properly by Toshiba Corporation, which would continue to exist after the merger. Results of the study revealed that the organization and technical experts existing at Japan Atomic Energy Operation Co. before the merger would properly incorporated into the existing system in Toshiba Corporation. Thus, it was confirmed that Toshiba Corporation after the merger would have technical capabilities required to install and operate nuclear reactors. The Atomic Nuclear Safety Commission started the above-mentioned study on the subject matter at the 32nd meeting, which was held on August 24, 1989, and reached the conclusion at the 34th meeting held on August 31, 1989.

    Current status of nuclear power plants in Japan is presented with the basic concepts against ageing of LWR plants which are considered to continue growing into the 21st century. Life management for aged NPPs is recognized to be important for the safe and reliable operation. In April 1996 MITI published the first report regarding the measures to cope with the aged NPPs. Two BWRs and one PWR were evaluated as aged NPPs in Phase-I Technical evaluation, which concluded that safe operation is possible with correct and adequate maintenance despite operation exceeded 30 years. The technology development items towards attaining further highly reliable management were indicated including the inspection/monitoring technology, the preventive maintenance/repair technology and ageing evaluation technology

    Full Text Available Abstract Background The rate of influenza vaccination in Japan has declined over the past several decades. It is essential to identify community-specific factors that affect attitudes toward vaccination, but such parameters have not yet been fully determined in Japan. The present study used the Health Belief Model (HBM to identify perceptions of influenza vaccination in a rural Japanese community. Methods All subjects were residents of a rural town in the southern part of Kyoto, Japan. An anonymous self-administered questionnaire was mailed to 846 randomly chosen households (containing 2,665 subjects. The survey explored gender, age, history of influenza, and factors associated with obtaining influenza vaccination, based on the HBM. Results A total of 1,182 valid responses (response rate, 44.4% were received. Sources of information that were associated with vaccination decisions were medical facilities for children (OR = 4.21; 95% CI: 1.17-15.1, workplaces for adults (OR = 2.40; 95% CI: 1.22-4.75, medical facilities, town office and family for elderly subjects (OR = 6.18; 95% CI: 2.42-15.7, OR = 5.59; 95% CI: 2.26-13.8 and OR = 3.29; 95%CI: 1.01-10.6. Subjects, in all age groups, who strongly agreed that the vaccine was effective were significantly more likely to be vaccinated (OR = 10.5; 95%CI: 2.68-41.7 for children; OR = 8.85; 95%CI: 4.61-16.9 for adults; OR = 19.9; 95%CI: 8.28-48.0 for the elderly. The vaccination rate of elderly subjects who expressed concerns regarding adverse vaccine effects (OR = 0.34, 95% CI: 0.15-0.78 or who were worried about practical barriers to the vaccination process (OR = 0.13; 95% CI: 0.05-0.31 was significantly lower than in other populations. Conclusions Our results indicate that vaccination coverage can be increased if accurate information on personal risk, severity of influenza illness, and efficacy of vaccination are provided by responsible information sources that are easily accessible.

    In this study, the shape recovery and mechanical properties of Ni{sub 54}Mn{sub 16}Fe{sub 9}Ga{sub 21} high-temperature shape memory alloy are improved simultaneously. This results from the low, about 4.4%, volume fraction of γ phase being almost completely distributed along grain boundaries. The recovery strain gradually increases with the increase in residual strain with a shape recovery rate of above 68%, up to a maximum value of 5.3%. The compressive fracture strain of Ni{sub 54}Mn{sub 16}Fe{sub 9}Ga{sub 21} alloy is about 35%. The results further reveal that when applying a high compression deformation two types of cracks form and propagate either within martensite grains (type I) or along the boundaries between martensite phase and γ phase (type II) in the present two-phase alloy.

    Dietary habit is closely associated with development of cancer and cardiovascular diseases, however little prospective evidence has been published for Japanese, whose dietary habit is substantially different from Western countries. Therefore, frequencies of food consumption, food preference, cooking method and acceptance of dietary advice were investigated at the baseline by two kinds of self-administered food frequency questionnaires. Dietary habits between urban and rural (Tokyo and Osaka vs. others), or between Okinawa and non-Okinawa revealed recognizable differences. The so-called westernized foods such as bread, beef and coffee were more consumed in the urban areas such as Tokyo and Osaka and also in Okinawa. The frequencies of salted food intake such as pickled vegetables and salted seafoods were remarkably low in Okinawa. Cooking methods for meats, seafoods and vegetables were also unique in Okinawa. No distinct geographical difference was shown in food preference and modification of dietary habit by dietary advice.

    Recalls of non-prescription drugs can contribute to preventing harm to human health, however, they also interrupt the supply of medicines to the market. The aim of the present study was to investigate the trends in non-prescription drug recalls in Japan. Class I, II, and III recalls reported from April 2009 to March 2014 were obtained from the websites of the Ministry of Health, Labour and Welfare and the Pharmaceuticals and Medical Devices Agency. Each drug recall was classified according to year, dosage form, therapeutic category, and reasons for the recall. The trends over the 5 year period were assessed for each class. A total of 220 recalls were reported in the 5-year study period. The numbers of drug recalls were 21, 16, 80, 58, and 45 in 2009, 2010, 2011, 2012, and 2013, respectively. The drugs recalled consisted of 177 internal medications, 35 topical agents, and 8 others. Drug recalls were observed in 12 therapeutic categories of drug effects. The largest number of recalls was for Chinese herbal medicines and crude drugs. Of all the drug recalls in 2011, Chinese herbal medicines and crude drugs produced by one manufacturer accounted for 84%. Slightly more than half (54%) of drug recalls were due to a violation of the regulations. One manufacturer recalled many drugs because of non-compliance with the standard regulations for manufacturing drugs after 2011. In conclusion, non-prescription drug recalls can occur for any drug regardless of the dosage form and therapeutic category.

    In Japan, atomic energy has become to accomplish the important role in energy supply. Recently the interest in the protection of global environment heightened, and the anxiety on oil supply has been felt due to the circumstances in Mideast. Therefore, the importance of atomic energy as an energy source for hereafter increased, and the future plan of nuclear fuel recycling in Japan must be promoted on such viewpoint. At present in Japan, the construction of nuclear fuel cycle facilities is in progress in Rokkasho, Aomori Prefecture. The prototype FBR 'Monju' started the general functional test in May, this year. The transport of the plutonium reprocessed in U.K. and France to Japan will be carried out in near future. This report presents the concrete measures of nuclear fuel recycling in Japan from the long term viewpoint up to 2010. The necessity and meaning of nuclear fuel recycling in Japan, the effort related to nuclear nonproliferation, the plan of nuclear fuel recycling for hereafter in Japan, the organization of MOX fuel fabrication in Japan and abroad, the method of utilizing recovered uranium and the reprocessing of spent MOX fuel are described.

Although topical steroid addiction or red burning skin syndrome had been mentioned as possible side effects of topical steroids in a 2006 review article in the Journal of the American Academy of Dermatology, no statement was made regarding this illness in the new guidelines. This suggests that there are still controversies regarding this illness. Here, we describe the clinical features of topical steroid addiction or red burning skin syndrome, based on the treatment of many cases of the illness. Because there have been few articles in the medical literature regarding this illness, the description in this article will be of some benefit to better understand the illness and to spur discussion regarding topical steroid addiction or red burning skin syndrome.

    Full Text Available A re-imagining of education is taking place throughout the world with the 21st century in mind and nowhere is this being tested, probed, and critiqued more than in Asia. This new era sees social phenomena as polycentric and polycontextual rather than bilateral or unidirectional. Asia is first and foremost where education in the 21st century is seeing its most spectacular engagement and growth. We view the Japa- nese example with its multiple, textured approaches as one of the heralds of this new global conversation for an education that responds to the transnational, transcultural characteristics of the new age that has daw- ned upon us. Combining Confucian, North American, European, and global approaches – all of which are having an impact on other nations of Asia – Japan represents the cutting edge of a new wave for understan- ding education that has movement as a central motif and strategy.

    Background The aim of this study is to estimate the lifetime and 12-month prevalence, severity, and treatment of Diagnostic and Statistical Manual of Mental Disorders 4th ed. (DSM-IV) mental disorders in Japan based on the final data set of the World Mental Health Japan Survey conducted in 2002–2006. Methods Face-to-face household interviews of 4,130 respondents who were randomly selected from Japanese-speaking residents aged 20 years or older were conducted from 2002 to 2006 in 11 community populations in Japan (overall response rate, 56%). The World Mental Health version of the World Health Organization Composite International Diagnostic Interview (WMH-CIDI), a fully structured lay administered psychiatric diagnostic interview, was used for diagnostic assessment. Results Lifetime/12-month prevalence of any DSM-IV common mental disorders in Japan was estimated to be 20.3/7.6%. Rank-order of four classes of mental disorders was anxiety disorders (8.1/4.9%), substance disorders (7.4/1.0%), mood disorders (6.5/2.3%), and impulse control disorders (2.0/0.7%). The most common individual disorders were alcohol abuse/dependence (7.3/0.9%), major depressive disorder (6.1/2.2%), specific phobia (3.4/2.3%), and generalized anxiety disorder (2.6/1.3%). While the lifetime prevalence of any mental disorder was greater for males and the middle-aged, the persistence (proportion of 12-month cases among lifetime cases) of any mental disorder was greater for females and younger respondents. Among those with any 12-month disorder, 15.3% were classified as severe, 44.1% moderate, and 40.6% mild. Although a strong association between severity and service use was found, only 21.9% of respondents with any 12-month disorder sought treatment within the last 12 months; only 37.0% of severe cases received medical care. The mental health specialty sector was the most common resource used in Japan. Although the prevalence of mental disorders were quite low, mental disorders were the second

  12. Japan's new energy policy

    International Nuclear Information System (INIS)

    2014-11-01

    Japan's energy policy is undergoing fundamental changes. The accident at TEPCO's Fukushima Daiichi nuclear power plant questions the future contribution of nuclear power in the national energy mix. Growing imports of fossil fuels to replace the lost nuclear capacity inflated energy prices and raise economic and energy security challenges. At the same time, the US shale gas and oil revolution is reshaping the global energy scene. Japan expects to take advantage of the trend to eliminate the 'Asian premium' on natural gas prices and expand cheaper natural gas consumption. These developments have driven the Government of Japan to review its energy policy from scratch and adopt a new Strategic Energy Plan. This new policy has far reaching implications for gas and coal development in Japan but also for the international markets as Japan is the world's largest LNG importer and the second largest coal importer. This document summarizes the key findings of a new report by CEDIGAZ 'Japan's new energy policy: In search for stable and competitive energy supply'. The report analyzes the current changes taking place on the gas and coal markets in Japan, in light of the new energy policy adopted in April 2014, and in particular the decision to restart safe nuclear power plants and push forward electricity market reforms

    Earlier studies have demonstrated that Deuterohaemin-AlaHisThrValGluLys (DhHP-6), a novel porphyrin-peptide, increases lifespan and enhances stress resistance of Caenorhabditis elegans. To explore the possible mechanisms, in this study we investigated the roles of SIR-2.1 and DAF-16 in DhHP-6's function using wild-type and various other mutant strains of C. elegans. DhHP-6's effect was dependent upon DAF-16, and it did not extend the lifespan of the loss-of-function daf-16 mutant strain (daf-16(mu86) I). DhHP-6 enhanced DAF-16 translocation from cytoplasm to nuclei; and it increased DAF-16's transcriptional activity, likely by activating the SIR-2.1/DAF-16 complex. DhHP-6's effect was also dependent upon SIR-2.1, and it did not increase the lifespan of the worms with SIR-2.1 deacetylase activity inhibited by niacin amide (SIR-2.1 inhibitor) and SIR-2.1 RNA interference (RNAi). Niacin amide and RNAi increased DAF-16's nuclear localization; but they decreased DAF-16's transcriptional activity, likely by preventing the formation of the SIR-2.1/DAF-16 complex. These results suggest that DhHP-6 extends the lifespan of C. elegans via SIR 2.1 and DAF-16, and they provide new insights into the molecular mechanisms of aging.

    Full Text Available Background and Objective. H. pylori infection causes a chronic inflammation in the gastric mucosa. However, this local inflammation may result in extra-digestive conditions. Our aim is to investigate the relationship between H. pylori infection and osteoporosis in Japan. Methods. This cross-sectional study was conducted among outpatients at the Juntendo University Hospital between 2008 and 2014. Participants for patient profile, H. pylori infection status, comorbidity, internal medical therapies, lumbar dual-energy X-ray absorptiometry (DXA, and bone turnover marker were collected and upper gastrointestinal endoscopy for reflux esophagitis, hiatal hernia, peptic ulcer disease (PUD, and endoscopic gastric mucosal atrophy (EGA was performed. The diagnosis of osteoporosis was performed in accordance with the Japanese criteria. We investigated risk factors of osteoporosis. Results. Of the eligible 200 study subjects, 41 cases were of osteoporosis. Bivariate analysis showed that age, being female, BMI, alcohol, smoking, H. pylori, bone-specific ALP, PUD, and EGA were related to osteoporosis. Multivariate analysis showed that age (OR 1.13; 95%CI 1.07–1.20, being female (OR 4.77; 95%CI 1.78–12.77, BMI (OR 0.79; 95%CI 0.68–0.92, H. pylori (OR 5.33; 95%CI 1.73–16.42, and PUD (OR 4.98; 95%CI 1.51–16.45 were related to osteoporosis. Conclusions. H. pylori infection may be a risk factor of osteoporosis in Japan.

    2004-01-01

    21 Ne and 21 Na are well bound nuclei and there is a large amount of data available up to considerable excitation energy, and this imposes a severe test on the structure models. Preliminary results for the structure of these nuclei based on three body models ( 21 Ne= 16 O+α+n and 21 Na= 16 O+α+p) are presented. Three-body calculations without core excitation produce the positive parity states in fair agreement with experiment, while slightly overbinding the systems. As expected, these models fail to reproduce the low lying negative parity states, which are predicted by shell model to have mainly core excited configurations. As a first step we have included the 3 - state of 16 O in our model. Convergence issues will be discussed. Results suggest that more excited states may be required to describe the system

    Suicide is one of the leading causes of mortality in both South Korea and Japan. The study aims to compare the descriptive epidemiology of suicide over the last two decades (1985-2006) and to explore the conditions associated with the different distribution of suicides in both countries. Age-standardized suicide rates were obtained from the OECD Health Data 2009. Age-specific suicide rates for the age groups were calculated from the WHO Mortality Database. Suicide methods were identified based on ICD-10. Through 1980-2000, Japan showed consistently higher suicide rates compared to Korea. However, from the mid-1990s, Korea showed an acute increase of suicides and finally surpassed Japan; the age-standardized suicide rate of Korea increased from 10.2 (per 100,000) in 1985 to 21.5 in 2006, while it slightly increased from 18.4 to 19.1 in Japan. The highest age-specific suicide rate was observed among Japanese men aged 45-64 years and Korean men aged over 64 years. The increase of elderly suicides among Korean women was notable. The gender ratio increased in Japan and decreased in Korea, respectively. The preferred suicide methods were hanging and pesticide poisoning in Korea and hanging in Japan. Because of the limited number of observations, hypothesis testing of specific risk factors was not possible. Age and gender distribution of suicide rates differed considerably between the two countries. Welfare protection throughout the life course in both countries, and pesticide regulation in Korea would be helpful in reducing the burden of suicide mortality in both countries, even if the social values could not be changed in a short time.

    In Japan, influenza like epidemics were described many times since Heian era. However, Spanish flu as the modern medicine invaded Japan in 1918, thus almost infected 390,000 patients died with associated pneumonia. After the discovery of influenza virus in 1933, Japan experienced pandemic influenza--Asian flu(H2N2) in 1957. After about 10 years, Hong Kong flu (H3N2) came to Japan at 1968. However, we had many reliable antibiotics but had not any antiviral drug at the early time. After year 2000, we fortunately obtained reliable three antiviral drugs such as amantadine, oseltamivir and zanamivir. Moreover, very useful rapid test kits for influenza A and B viruses were developed and used in Japan. 2009 H1N1 influenza epidemic occured in Japan after the great epidemic in Mexico and North America but elderly patient was few. With together, host conditions regarding with high risk are changing. Lessons from past several pandemic influenza are those that many issues for changing high risk conditions, viral genetic changes, developing antiviral agents, developing new useful vaccins and determinating bacterial secondary pathogens are important.

    Electricity is needed as an infrastructure to support the national economic growth. For economic development sustainability, energy alternatives should be provided. Nuclear Power Plant (NPP) become the alternative of electricity generation for optimum energy mix in Indonesia and planned to operate in the 2016. Several studies have already done to prepare the NPP construction. This study focused on NPP performance especially PWR type in Asia, namely Japan and South Korea. Methodology used in this is literature tracing and a small calculation. The energy availability per unit per year is used as a parameter for evaluating the NPP performance. This conclusion are 1) the amount of NPP - PWR type in Japan is 22 units with total operational experiences 526 reactor-years and the average energy availability factor about 70.7% per unit per year. Meanwhile for the same type South Korea has 16 unit with total operational experience 222 reactor-years and average availability factor per unit per year is about 86.9%. 2) the 1000 class of PWR type both South Korea and Japan have 14 units. The operational experiences for thi class is 170 reactor-year for South Korean and 307 reactor-year for Japan. Meanwhile the average availability factor per unit per year is about 87.0% for South Korea and 69.6% for Japan. 3) the average availability factor is closed to capacity factor, so is important for real figure in assuming the techno-economic parameters, because it will influence the result o economic calculation.

    Full text: A team of international experts today completed a preliminary assessment of the strategy and plans being considered by the Japanese authorities to remediate the areas off-site the Fukushima Dai-ichi Nuclear Power Plant reported to have elevated levels of radiation. The IAEA dispatched the mission to Japan on 7 October following a request from the country's Government. The mission, comprising 12 international and IAEA experts from several countries, visited numerous locations in the Fukushima Prefecture and conducted meetings in Tokyo and Fukushima with Japanese officials from several Ministries and institutions. ''The meetings held and visits made by the team over the last eight days gave us a first-hand appreciation of the extraordinary efforts and dedication on the part of Japanese people in their effort to remediate the areas affected by elevated levels of radiation in the Fukushima Prefecture,'' says Mr. Juan Carlos Lentijo, Team Leader and General Director for Radiation Protection at Spain's nuclear regulatory authority. ''As Japan continues its current remediation efforts, it is our belief that this work will bring relief to the populations who are affected by the consequences of the nuclear accident at the Fukushima Dai-ichi nuclear power plant.'' In a Preliminary Summary Report delivered to Japanese authorities today, the team prepared a set of conclusions including, though not limited to, the following: - Japan developed an efficient program for remediation - allocating the necessary legal, financial and technological resources to bring relief to the people affected by the accident, with priority being given to children. The Team was impressed with the strong commitment to the remediation effort from all institutions and parties involved, including the public; - Japan has also taken practical measures to inform the public and involve residents and local institutions in the process of defining its remediation strategy; - Japan is advised to avoid

    This report summarizes the status of electronic manufacturing and packaging technology in Japan in comparison to that in the United States, and its impact on competition in electronic manufacturing in general. In addition to electronic manufacturing technologies, the report covers technology and manufacturing infrastructure, electronics manufacturing and assembly, quality assurance and reliability in the Japanese electronics industry, and successful product realization strategies. The panel found that Japan leads the United States in almost every electronics packaging technology. Japan clearly has achieved a strategic advantage in electronics production and process technologies. Panel members believe that Japanese competitors could be leading U.S. firms by as much as a decade in some electronics process technologies. Japan has established this marked competitive advantage in electronics as a consequence of developing low-cost, high-volume consumer products. Japan's infrastructure, and the remarkable cohesiveness of vision and purpose in government and industry, are key factors in the success of Japan's electronics industry. Although Japan will continue to dominate consumer electronics in the foreseeable future, opportunities exist for the United States and other industrial countries to capture an increasingly large part of the market. The JTEC panel has identified no insurmountable barriers that would prevent the United States from regaining a significant share of the consumer electronics market; in fact, there is ample evidence that the United States needs to aggressively pursue high-volume, low-cost electronic assembly, because it is a critical path leading to high-performance electronic systems.

This is to be published quaterly in principle and compiled information by oral presentation presented at main conferences, symposia and other kind of formal meetings in the field of nuclear science and technology in Japan. Not all of the oral presentation is always contributed later to a proceeding or a journal as a full paper in Japan. In some cases, the pre-conference paper might be a only publication of the oral presentation. In this meaning, this journal could be used as a search tool for the subjects and the projects of nuclear research and development in progress. (author)

    In the consumer electronics industry, precision processing technology is the basis for enhancing product functions and for minimizing components and end products. Throughout Japan, manufacturing technology is seen as critical to the production and assembly of advanced products. While its population has increased less than 30 percent over twenty-five years, Japan's gross national product has increase thirtyfold; this growth has resulted in large part from rapid replacement of manual operations with innovative, high-speed, large-scale, continuously running, complex machines that process a growing number of miniaturized components. The JTEC panel found that introduction of next-generation electronics products in Japan goes hand-in-hand with introduction of new and improved production equipment. In the panel's judgment, Japan's advanced process technologies and equipment development and its highly automated factories are crucial elements of its domination of the consumer electronics marketplace - and Japan's expertise in manufacturing consumer electronics products gives it potentially unapproachable process expertise in all electronics markets.

    2014-12-01

    In Japan, damage and disasters from historical large earthquakes have been documented and preserved. Compilation of historical earthquake documents started in the early 20th century and 33 volumes of historical document source books (about 27,000 pages) have been published. However, these source books are not effectively utilized for researchers due to a contamination of low-reliability historical records and a difficulty for keyword searching by characters and dates. To overcome these problems and to promote historical earthquake studies in Japan, construction of text database started in the 21 century. As for historical earthquakes from the beginning of the 7th century to the early 17th century, "Online Database of Historical Documents in Japanese Earthquakes and Eruptions in the Ancient and Medieval Ages" (Ishibashi, 2009) has been already constructed. They investigated the source books or original texts of historical literature, emended the descriptions, and assigned the reliability of each historical document on the basis of written age. Another database compiled the historical documents for seven damaging earthquakes occurred along the Sea of Japan coast in Honshu, central Japan in the Edo period (from the beginning of the 17th century to the middle of the 19th century) and constructed text database and seismic intensity data base. These are now publicized on the web (written only in Japanese). However, only about 9 % of the earthquake source books have been digitized so far. Therefore, we plan to digitize all of the remaining historical documents by the research-program which started in 2014. The specification of the data base will be similar for previous ones. We also plan to combine this database with liquefaction traces database, which will be constructed by other research program, by adding the location information described in historical documents. Constructed database would be utilized to estimate the distributions of seismic intensities and tsunami

    Full Text Available Objective: This study investigates the influence of personal characteristics and health-related variables on the care dependency status among elderly in-patients with clinically diagnosed Alzheimer’s disease in two countries. Methods: A descriptive cross-cultural survey was administered to a convenience sample of 137 elderly in-patients. Patients were recruited from a hospital in Japan (N = 77 and from a nursing home in the Netherlands (N = 60. Results: In both countries, almost all participants are assessed on the severity level of care dependency in the range of “completely care dependent” (Japan: 35.1%; the Netherlands: 20.0%, or “to a great extent care dependent” (Japan: 24.7%; the Netherlands: 45.0%, to “partially care dependent” (Japan: 22.1%; the Netherlands: 21.7%. Conclusion: This study demonstrates that there is no interdependence between the severity level of care dependency and personal characteristics of patients with Alzheimer’s disease in both countries. Regarding the interplay of health-related variables on the severity level of care dependency, a difference was found between countries.

    The patterns of radical radiation therapy for prostate cancer are unclear in Japan. A Patterns of Care Study was performed throughout Japan to examine the patterns of radiation therapy for prostate cancer. From 1999 to 2000, extramural audits were performed on 50 randomly selected institutions (∼7% of all institutions in Japan). Detailed information was collected on a total of 311 prostate cancer patients without evidence of distant metastases, who were treated by radiation therapy between 1996 and 1998. Of these 311 patients, 162 treated radically using photon beams were analyzed in this study. Eighty percent of the patients had high-risk diseases defined as T3 or T4 tumors, a pretreatment prostate-specific antigen level >20 ng/ml or poorly differentiated adenocarcinoma. Androgen ablation was performed in 85.8% of patients and the median duration of hormonal therapy before and after radiation therapy was 5.3 and 21.4 months, respectively. The median total dose of radiation therapy to the prostate was 65.0 Gy (range: 20-74 Gy). The 3-year overall and biochemical relapse-free survival rates were 86.7 and 86.1%, respectively. Late toxicity was mild, with only nine patients (5.6%) exhibiting grade 2 late morbidity. The majority of the patients who received radical radiation therapy in Japan have high-risk disease. Androgen ablation plus radiation therapy was commonly used to treat these patients and resulted in high rates of initial control with a low risk of complications. (author)

  12. Epidemiology of diabetes mellitus in Japan

    1964-03-12

    The clinical and epidemiological features of diabetes mellitus in Japan have been compiled and compared with data from other countries. Diabetes is basically the same in Japan as elsewhere: however, consideration of important differences has led to the following conclusions: The rarity of ketoacidosis in Japan is due to the mild carbohydrate defect present in most diabetics. The mild carbohydrate intolerance in diabetics is probably in part due to a high carbohydrate intake. Diabetic retinopathy is more common in women than in men in Japan; there are limited and conflicting data from the West on this point, but retinopathy, nephropathy and neuropathy occur about as frequently in Japan as in the West. Because of marked dietary differences between Japan and Western countries, these findings suggest that dietary fat has no significance in the pathogenesis of these lesions. Peripheral gangrene is distinctly unusual in Japanese diabetics. This suggests that either: the responsible vascular lesions are different from those responsible for nephropathy and retinopathy; or that small vessel lesions are the same but the lack of large vessel atherosclerosis in the population accounts for the decreased incidence of gangrene. Men have diabetes 2 or 3 times as commonly as women in Japan. If sex-limited inheritance is discarded as a possible reason, it is likely that adult-onset diabetes is more common in men than women except in those countries (the West) where women gain relatively large amounts of weight. The rarity of juvenile diabetes in Japan is best explained by the infrequency of responsible genetic factors. As a consequence, it is likely that juvenile diabetes is caused by different or additional genetic factors which are not significant in adult-onset diabetes. Diabetes prevalance varies sufficiently between different localities in the same country to render the concept of national prevalance of doubtful usefulness. 55 references, 3 figures, 3 tables.

    A new muon channel, MUSIC, is being constructed at the Research Center for Nuclear Physics (RCNP) at Osaka University in Japan. The muon channel utilizes a strong solenoidal magnetic field to collect pions and to transport muons. A large-bore superconducting coil encloses the pion-production target to capture pions with a large solid angle. A long solenoid magnet transports pions and muons with the capability to select the charge and momentum of the particles. The design of the solenoid channel is described in this paper.

    Sleep problems are associated with problems of cognitive functioning, learning, attention and school performance. It has been found that sleep problems are highly prevalent in children with Autistic spectrum disorders (ASD), with rates ranging from 40% to 80%. We aimed to identify the prevalence of sleep problems on children with ASD in Indonesia and Japan. A cross-sectional study was conducted in Surabaya, Indonesia and Kobe, Japan. Children aged 4 -10 years old were enrolled using stratified cluster sampling. Children's Sleep Habits Questionnaire-Abbreviated (CSHQ-A) was used in this research to assess the sleep problems, consisted of 22 questions (NICHD SECCYD-Wisconsin). Data were analyzed with Mann-Whitney U test to compare the CSHQ-A scores between Indonesian and Japanese children, while the proportion of sleep problems was evaluated by chi-square test with 95% confidence interval. Fifty children with ASD were included in this study, 25 children from Kobe, Japan and 25 children from Surabaya, Indonesia. The prevalence of sleep problems on children with ASD was 60% (15 children) in Indonesia and 16% (4 children) in Japan respectively. There were significant differences in total waking during the night and in morning wake for the CSHQ-A between children from Indonesia and Japan (psleep problems on children with ASD was higher in children from Indonesia than from Japan.

    Investigations were carried out on hydrothermally altered coherent dacitic dykes samples from (USDP-4) drill core at Mt Unzen stratovolcano (Shimabara/Japan). XRF, XRD, EMPA, and C-O-isotope analysis led to insights concerning chemistry, mineralogy, and intensity of alteration as well as the origin of carbonate-precipitating fluids. Additionally a textural characterization of the occurring replacement features in the magma conduit zone was performed. The occurrence of the main secondary phases such as chlorite, pyrite, carbonates, and R1 (Reichweite parameter) illite-smectite indicate a weak to moderate propylitic to phyllic hydrothermal alteration. The dacitic samples of the dykes show different hydrothermal alteration features: (i) carbonate pseudomorphs after hornblende as well as core and zonal textures due to replacement of plagioclase by R1 illite-smectite, (ii) colloform banded fracture fillings and fillings in dissolution vugs, and (iii) chlorite and R1 illite-smectite in the groundmass. Carbonates in fractures comprise iron-rich dolomite solid solutions ("ankerite") and calcite. Isotopic values of d13Cvpdb = -4.59 ± 0.6‰ and d18Ovpdb = -21.73 ± 0.5‰ indicate a hydrothermal-magmatic origin for the carbonate formation. The chlorite-carbonate-pyrite index (CCPI) and the Ishikawa alteration index (AI), applied to the investigated samples show significant differences (CCPI=52.7-57.8; AI=36.1-40.6) indicating their different degree of alteration. According to Nakada et al., 2005, the C13 to C16 dykes represent the feeder dyke from the latest eruption (1991-1995) whereas C8 represents an earlier dyke feeder dyke from an older eruption. Weakest conduit alteration, which was obtained in samples C16-1-5 and C13-2-5, correlates with the alteration degree of the pristine dome rocks. Highest CCPI value was determined for sample C14-1-5 and the highest AI value was determined for sample C15-2-6. The degrees of alteration do not indicate highest alteration of the

    Six hundreds and eighty earthquakes causing significant damage have been recorded since the 7. century in Japan. It is important to recognize faults that will or are expected to be active in future in order to help reduce earthquake damage, estimate earthquake damage insurance and siting of nuclear facilities. Such faults are called 'active faults' in Japan, the definition of which is a fault that has moved intermittently for at least several hundred thousand years and is expected to continue to do so in future. Scientific research of active faults has been ongoing since the 1930's. Many results indicated that major earthquakes and fault movements in shallow crustal regions in Japan occurred repeatedly at existing active fault zones during the past. After the 1995 Southern Hyogo Prefecture Earthquake, 98 active fault zones were selected for fundamental survey, with the purpose of efficiently conducting an active fault survey in 'Plans for Fundamental Seismic Survey and Observation' by the headquarters for earthquake research promotion, which was attached to the Prime Minister's office of Japan. Forty two administrative divisions for earthquake disaster prevention have investigated the distribution and history of fault activity of 80 active fault zones. Although earthquake prediction is difficult, the behaviour of major active faults in Japan is being recognised. Japan Nuclear Cycle Development Institute (JNC) submitted a report titled 'H12: Project to Establish the. Scientific and Technical Basis for HLW Disposal in Japan' to the Atomic Energy Commission (AEC) of Japan for official review W. The Guidelines, which were defined by AEC, require the H12 Project to confirm the basic technical feasibility of safe HLW disposal in Japan. In this report the important issues relating to fault activity were described that are to understand the characteristics of current fault movements and the spatial extent and magnitude of the effects caused by these movements, and to

    Childcare issue and family care issue are critical factors for women doctors to make a career as a neurologist in Japan. To know the actual business conditions of Japanese neurologists an online questioner survey was conducted. Answers were obtained from 737 members of Japanese Society of Neurology and 21 neurological medical facilities. Most of the answers were form members at three major metropolitan areas such as Tokyo, Osaka and Nagoya. Nobody from some prefectures was replied any answer. Almost sixty percent woman doctors had to change their working style from full time to part time at their child raising period and had difficulty with returning to full time job. Some neurologists have answered they used paid vacation to care their families and they felt they could not keep it for a longer period. At 70 percent of medical facilities sick child day care center were not operated. Opinions form members extremely varied from "In the first place woman doctors are unnecessary"to "With the help of the partner I have survived my child raising period".

    2013-01-01

    This study discusses the causes of the increase in Japan's energy intensity, defined as energy consumption divided by GDP, since the early 1990s. The significant reduction in Japan's energy intensity ceased in the early 1980s and has even slightly increased since the early 1990s, indicating that Japan seemingly stopped taking aggressive action to improve energy use. However, further analysis at prefecture level and sector level provides additional insight on energy intensity trends. To analyze the causes of the increase in Japan's energy intensity, energy intensity is decomposed into energy efficiency (improvements in energy efficiency) and energy activity (structural changes from the secondary sector to the tertiary sector of the economy). Our result indicates that the non-uniform energy intensity trends between prefectures are attributed to a high variability in energy efficiency. At sector level, we estimate the income elasticity of energy consumption in each sector and find that a structural change in energy consumption behaviors occurred in all sectors at different time points. The industrial sector and commercial sector became less energy efficient after 1981 and 1988, respectively, which is presumably responsible for the deterioration of Japan's energy intensity since the early 1990s. - Highlights: • We examine why the reduction in Japan's energy intensity increased in the early 1990s. • There is a high variability in energy intensity trends between regions. • The structural changes in energy consumption behaviors occurred in sector level. • These changes may be responsible for the deterioration of Japan's energy intensity

    2013-04-01

    Significant dioxin (polychlorinated dibenzo-para-dioxins (PCDDs)/polychlorinated dibenzo-furans (PCDFs)) pollution from a municipal solid waste incinerator was discovered in 1997 in Osaka prefecture/Japan. The cause and mechanism of pollution was identified by a detailed assessment of the environment and incinerator plant. The primary sources of PCDD/PCDF pollution were high dioxin releases from an intermittently operated waste incinerator with PCDD/PCDF emissions of 150 ng-TEQ/Nm(3). PCDD/PCDF also accumulated in the wet scrubber system (3,000 μg TEQ/L) by adsorption and water recirculation in the incinerator. Scrubber water was air-cooled with a cooling tower located on the roof of the incinerator. High concentrations of dioxins in the cooling water were released as aerosols into the surrounding and caused heavy soil pollution in the area near the plant. These emissions were considered as the major contamination pathway from the plant. Decontamination and soil remediation in and around the incinerator plant were conducted using a variety of destruction technologies (including incineration, photochemical degradation and GeoMelt technology). Although the soil remediation process was successfully finished in December 2006 about 3% of the waste still remains. The case demonstrates that releases from incinerators which do not use best available technology or which are not operated according to best environmental practices can contaminate their operators and surrounding land. This significant pollution had a large impact on the Japanese government's approach toward controlling dioxin pollution. Since this incident, a ministerial conference on dioxins has successfully strengthened control measures.

    This study exhaustively and historically investigated the status of drug lag for oncology drugs approved in Japan. We comprehensively investigated oncology drugs approved in Japan between April 2001 and July 2014, using publicly available information. We also examined changes in the status of drug lag between Japan and the United States, as well as factors influencing drug lag. This study included 120 applications for approval of oncology drugs in Japan. The median difference over a 13-year period in the approval date between the United States and Japan was 875 days (29.2 months). This figure peaked in 2002, and showed a tendency to decline gradually each year thereafter. In 2014, the median approval lag was 281 days (9.4 months). Multiple regression analysis identified the following potential factors that reduce drug lag: "Japan's participation in global clinical trials"; "bridging strategies"; "designation of priority review in Japan"; and "molecularly targeted drugs". From 2001 to 2014, molecularly targeted drugs emerged as the predominant oncology drug, and the method of development has changed from full development in Japan or bridging strategy to global simultaneous development by Japan's taking part in global clinical trials. In line with these changes, the drug lag between the United States and Japan has significantly reduced to less than 1 year.

    In 2008, Japan Atomic Energy Commission of Cabinet Office performed the study of current status of food irradiation in the world. The results showed that the total quantity of irradiated foods in 2005 was 405,000 tons. Seven main countries for food irradiation were China, USA, Ukraine, Brazil, South Africa, Vietnam and Japan. In Japan, only the potato irradiation for sprout inhibition is continued more than 35 years since 1974 but the quantity is decreasing. On the other hand, the food irradiation of Vietnam has been developed rapidly in a short time to export the frozen seafood and fruit. This paper shows the status of food irradiation in Vietnam and Japan, and the progress in both countries after 2005. (author)

  8. Japan's National Security: Structures, norms, and policies

    International Nuclear Information System (INIS)

    Katzenstein, P.J.; Okawara, N.

    1993-01-01

    Japan's national security policy has two distinctive aspects that deserve analysis. First, Japan's definition of national security goes far beyond traditional military notions. National security is viewed in comprehensive terms that also include economic and political dimensions. The second feature of Japan's security policy worth explanation is a distinctive mixture of flexibility and rigidity in the process of policy adaptation to change: flexibility on issues of economic security, rigidity on issues of military security, and flexibility combined with rigidity on issues of political security. With the end of the Cold War and changes in the structure of the international system, it is only natural that we ask whether and how Japan's national security policy will change as well. Optimists insist that the Asian balance of power and the US-Japan relationship will make Japan aspire to be a competitive, noninterventionist trading state that heeds the universal interest of peace and profit rather than narrow aspirations for national power. Pessimists warn us instead that the new international system will finally confirm Herman Kahn's prediction of 1970: Japan will quickly change to the status of a nuclear superpower, spurred perhaps by what some see as a dangerous rise of Japanese militarism in the 1970s and 1980s

    In order to reflect the lessons learned from the Fukushima Daiichi nuclear power plant accident, a simulator which is named NANAS (Northeast Asia Nuclear Accident Simulator) for overseas nuclear accident has been developed. It is composed of three modules: source-term estimation, atmospheric dispersion prediction and dose assessment. For the source-term estimation module, the representative reactor types were selected as CPR1000, BWR5 and BWR6 for China, Japan and Taiwan, respectively. Considering the design characteristics of each reactor type, the source-term estimation module simulates the transient of design basis accident and severe accident. The atmospheric dispersion prediction module analyzes the transport and dispersion of radioactive materials and prints out the air and ground concentration. Using the concentration result, the dose assessment module calculates effective dose and thyroid dose in the Korean Peninsula region. In this study, a hypothetical severe accident in Japan was simulated to demonstrate the function of NANAS. As a result, the radiological consequence to Korea was estimated from the accident. PC-based nuclear accident simulator, NANAS, has been developed. NANAS contains three modules: source-term estimation, atmospheric dispersion prediction and dose assessment. The source-term estimation module simulates a nuclear accident for the representative reactor types in China, Japan and Taiwan. Since the maximum calculation speed is 16 times than real time, it is possible to estimate the source-term release swiftly in case of the emergency. The atmospheric dispersion prediction module analyzes the transport and dispersion of radioactive materials in wide range including the Northeast Asia. Final results of the dose assessment module are a map projection and time chart of effective dose and thyroid dose. A hypothetical accident in Japan was simulated by NANAS. The radioactive materials were released during the first 24 hours and the source

    The superconducting maglev system has been under development for the past 25 years in Japan. In last 17 years, running test on the 7 km Miyazaki test track has yielded important data for the maglev system development. In 1990, the maglev system gained the status of one of the national - funded projects in Japan. The government authorized the 42.8 km test line in Yamanashi Prefecture and R and D entered into a new phase. This new test line is planned to go through near Tokyo on the supposed Chuo line, which is expected to be a new important line connecting Tokyo and Osaka, the central part of Japan. This fact clearly explains the role of Yamanashi test line in the future. The construction of the Yamanashi test line is energetically promoted, to start running tests in spring of 1997. The situation of the technical development of the Yamanashi test line is reviewed here. (orig.)

    Despite the recent drop in world oil prices, the Japanese government is continuing to stress energy conservation, because Japan relies on imports for 85% of its total energy requirements and virtually 100% of its petroleum. Japan stresses long-term developments and sees conservation as an integral part of its 50- to 100-year transition from fossil fuels to nuclear and renewable sources of energy. The Japanese government is targeting new materials, biotechnology, and electronics technologies as the foundation of Japan's economy in the 21st century. Most government research programs in Japan are governed by aggressive timetables and fixed technical goals and are usually guaranteed funding over a 5- to 10-year period. Of the major energy conservation research programs, the best known is the Moonlight Project, administered by the Ministry of International Trade and Industry (MITI), and oriented towards end-use technologies such as Stirling engines and advanced heat pumps. Parts of MITI's Basic Technologies for Future Industries Program involve research in new materials and bioreactors. The Science and Technology Agency's Exploratory Research in Advanced Technologies (ERATO) Program is also investigating these technologies while emphasizing basic research. Other ministries supporting research related to energy conservation are the Ministry of Education, Science, and Culture and the Ministry of Construction. For 1985, government spending for energy conservation research was at least $50 million. Private sector funding of energy conservation research was $500 million in 1984. A brief outline of major programs and key participants is included for several of the most relevant technologies. An overview of Japan's experience in international scientific collaboration is also included.

We used this system, which we call the affinity evaluation and prediction (AEP system, to evaluate the interaction between 20 protein pairs. The system first executes a “round robin” shape complementarity search of the target protein group, and evaluates the interaction between the complex structures obtained by the search. These complex structures are selected by using a statistical procedure that we developed called ‘grouping’. At a prevalence of 5.0%, our AEP system predicted protein–protein interactions with a 50.0% recall, 55.6% precision, 95.5% accuracy, and an F-measure of 0.526. By optimizing the grouping process, our AEP system successfully predicted 10 protein pairs (among 20 pairs that were biologically relevant combinations. Our ultimate goal is to construct an affinity database that will provide cell biologists and drug designers with crucial information obtained using our AEP system.Keywords: protein–protein interaction, affinity analysis, protein–protein docking, FFT, massive parallel computing

  15. Waste-to-energy incineration plants as greenhouse gas reducers: a case study of seven Japanese metropolises.

    Municipal solid waste (MSW) incineration is a greenhouse gas (GHG) emitter; however, if GHG reductions, achieved by accounting for waste-to-energy, exceed GHG emissions, incineration can be considered as a net GHG reducer. In Japan, only 24.5% of MSW incineration plants perform energy recovery despite 80% of MSW being incinerated; therefore, there is great potential to extract more energy from MSW. In this study, the factors that should be considered to achieve net GHG reductions from incineration were analysed from a life cycle perspective. These considerations were then applied to the energy supply requirements in seven Japanese metropolises. Firstly, the carbon footprints of approximately 1500 incineration plants in Japan were calculated. Then, the incineration plants with negative carbon footprint values were classified as net GHG reducers. Next, the processes that contribute to the carbon footprint were evaluated, and two processes-plastic burning and electricity savings-were found to have the greatest influence. Based on the results, the energy supply requirements were analysed and discussed for seven metropolises (Sapporo, Tokyo, Nagoya, Osaka, Kobe, Takamatsu and Fukuoka) taking into account the energy demands of households. In Kobe, 16.2% of the electricity demand and 25.0% of the hot water demand could be satisfied by incineration to realise a net GHG reducer, although urban design for energy utilisation would be required.

  16. Estimating the risk of parvovirus B19 infection in blood donors and pregnant women in Japan.

    Full Text Available BACKGROUND: Seroepidemiological study of parvovirus B19 has not taken place for some 20 years in Japan. To estimate the risk of parvovirus B19 infection in Japan among blood donors and pregnant women in this century, a seroepidemiological survey and statistical modeling of the force of infection were conducted. METHODOLOGY/PRINCIPAL FINDINGS: The time- and age-specific seroprevalence data were suggestive of strong age-dependency in the risk of infection. Employing a piecewise constant model, the highest forces of infection of 0.05 and 0.12 per year were observed among those aged 0-4 and 5-9 years, respectively, while estimates among older individuals were less than 0.01 per year. Analyzing the antigen detection data among blood donors, the age-specific proportion positive was highest among those aged 30-39 years, agreeing with the presence of dip in seroprevalence in this age-group. Among pregnant women, up to 107 fetal deaths and 21 hydrops fetalis were estimated to have occurred annually across Japan. CONCLUSIONS: Seroepidemiological profiles of PVB19 infection in Japan was characterized with particular emphasis on the risk of infection in blood donors and the burden of infection among pregnant women. When a vaccine becomes available in the future, a similar seroepidemiological study is expected to play a key role in planning the appropriate immunization policy.

    Diagnostic reference levels (DRLs) have not been established in Japan. To propose DRLs for CT of the head, chest and abdomen for three pediatric age groups. We sent a nationwide questionnaire by post to 339 facilities. Questions focused on pediatric CT technology, exposure parameters, CT protocols, and radiation doses for age groups <1 year, 1-5 years, and 6-10 years. For the three age groups in the 196 facilities that responded, the 75th percentile values of volume CT dose index based on a 16-cm phantom (CTDI vol 16 [mGy]) for head, chest and abdominal CT were for infants 39.1, 11.1 and 12.0, respectively; for 1-to 5-year-olds 46.9, 14.3 and 16.7, respectively; and for 6-to 10-year-olds 67.7, 15.0 and 17.0, respectively. The corresponding dose-length products (DLP 16 [mGy·cm]) for head, chest and abdominal CT were for infants 526.1, 209.1 and 261.5, respectively; for 1-to 5-year-olds 665.5, 296.0 and 430.8, respectively; and for 6-to 10-year-olds 847.9, 413.0 and 532.2, respectively. The majority of CTDI vol 16 and DLP 16 values for the head were higher than DRLs reported from other countries. For risk reduction, it is necessary to establish DRLs for pediatric CT in Japan.

    A total of 557 fecal specimens from infants and children with acute gastroenteritis in five places (Maizuru, Tokyo, Sapporo, Saga and Osaka) in Japan from July 2002 to June 2003 were tested for the presence of diarrheal viruses by RT-PCR, PRHA, RNA-PAGE and latex agglutination methods. Of these, 56.4% (314) were found positive for diarrheal viruses. Among them, group A rotavirus was the most prevalent (43.6%, 137 of 314) followed by norovirus (29.9%, 94 of 314), adenovirus (7.6%, 24 of 314), group C rotavirus (6.4%, 20 of 314), sapovirus (5.1%, 16 of 314) and astrovirus (1.6%, 5 of 314), respectively. A high rate (7.4%, 19 of 314) of viral mixed infections, including one triple infection (adenovirus, norovirus and astrovirus) was demonstrated. Norovirus infection that usually has a peak during November and January in Japan was detected year-round and highest in September in our study. Norovirus was subjected to molecular genetic analysis by sequencing. The results clearly indicated that norovirus group II was a dominant genogroup (94.3%, 100 of 106). It is noteworthy that noroviruses detected in this study were classified into 8 genotypes (GI/1, GI/4, GII/2, GII/3, GII/4, GII/5, GII/6 and GII/12). Of these, NVGII/4 was the predominant genotype, followed by NVGII/6, and these presented 75.6% (80 of 106) and 11.3% (12 of 106), respectively. Another interesting feature in our study was the sudden appearance and disappearance of SaitamaU16-like strains belonging to NVGII/6 in the short period (January 2003 to June 2003). Our findings confirmed the presence of many diarrheal viruses co-circulating among Japanese infants and children and showed the great genetic diversity among norovirus.

  20. Isolation and characteristics of Shiga toxin 2f-producing Escherichia coli among pigeons in Kyushu, Japan.

    Full Text Available An increasing number of Shiga toxin 2f-producing Escherichia coli (STEC2f infections in humans are being reported in Europe, and pigeons have been suggested as a reservoir for the pathogen. In Japan, there is very little information regarding carriage of STEC2f by pigeons, prompting the need for further investigation. We collected 549 samples of pigeon droppings from 14 locations in Kyushu, Japan, to isolate STEC2f and to investigate characteristics of the isolates. Shiga toxin stx 2f gene fragments were detected by PCR in 16 (2.9% of the 549 dropping samples across four of the 14 locations. We obtained 23 STEC2f-isolates from seven of the original samples and from three pigeon dropping samples collected in an additional sampling experiment (from a total of seven locations across both sampling periods. Genotypic and phenotypic characteristics were then examined for selected isolates from each of 10 samples with pulsed-field gel electrophoresis profiles. Eight of the stx 2f gene fragments sequenced in this study were homologous to others that were identified in Europe. Some isolates also contained virulence-related genes, including lpfA O26, irp 2, and fyuA, and all of the 10 selected isolates maintained the eae, astA, and cdt genes. Moreover, five of the 10 selected isolates contained sfpA, a gene that is restricted to Shiga toxin-producing E. coli O165:H2 and sorbitol-fermenting Shiga toxin-producing E. coli O157:NM. We document serotypes O152:HNM, O128:HNM, and O145:H34 as STEC2f, which agrees with previous studies on pigeons and humans. Interestingly, O119:H21 was newly described as STEC2f. O145:H34, with sequence type 722, was described in a German study in humans and was also isolated in the current study. These results revealed that Japanese zoonotic STEC2f strains harboring several virulence-related factors may be of the same clonal complexes as some European strains. These findings provide useful information for public health
