    The potentials of bubble technology in ultrasound has been investigated thoroughly in the last decade. Japan has entered as one of the leaders in bubble technology in ultrasound since Sonazoid (Daiichi Sankyo & GE Healthcare) was marketed in 2007. The 85th Annual Scientific Meeting of The Japan Society of Ultrasonics in Medicine held in Tokyo from May 25 to 27, 2012 is where researchers and clinicians from all over Japan presented recent advances and new developments in ultrasound in both the medical and the engineering aspects of this science. Even though bubble technology was originally developed simply to improve the conventional ultrasound imaging, recent discoveries have opened up powerful emerging applications. Bubble technology is the particular topic to be reviewed in this report, including its mechanical advances for molecular imaging, drug/gene delivery device and sonoporation up to its current clinical application for liver cancers and other liver, gastrointestinal, kidney and breast diseases.

    Full Text Available The Tokyo Tower and the Tokyo Skytree are the two most recognizable landmarks on the skyline of Japan’s capital. By means of a documental revision, a textual interpretative analysis of media contents, participant observation and unstructured interviews, the objective of this article is to identify the development of these towers as symbols of Tokyo and Japan. It is found that, with more than half a century of existence, the Tokyo Tower represents the successful post-war Japanese society, while in just five years the Tokyo Skytree has become a symbol of Japanese national spirit and resilience in an era of multiple crises. Both broadcasting towers are regularly portrayed in Japanese media linked to narratives of romance, dreams, family and community. Also, enhanced by their special lightening at night, they stand as attractive backgrounds for locals and visitors in relevant events in their lives.

    2017-09-01

    Long-term climate changes related with urbanization in Tokyo, Japan, and recent temperature and heavy rainfall distribution in the Tokyo metropolitan area are reviewed. A relatively high temperature increase in annual mean temperature at the rate of 3.0°C/century was detected in Tokyo for the period 1901-2015. Some observational evidence showed the existence of both thermal and mechanical effects of urbanization on recent heavy rainfall occurrences, and modeling studies also support precipitation enhancement. Urban influences were recognized in other climatological elements, such as number of fog days, relative humidity, and wind circulation. Copyright © 2017. Published by Elsevier B.V.

  5. Lessons from Japan: Resilience after Tokyo and Fukushima

    Full Text Available In the spring of 1995 Japan experienced the world’s first major terrorist attack using chemical weapons by a little-known religious cult called Aum Shinrikyo. The attack on the Tokyo subway, which killed 13 people, was the first lethal case of a non-state actor using a chemical agent against a civilian population. In March 2011, following a 9.0 magnitude earthquake in Japan, the Fukushima Daiichi nuclear reactor experienced a full meltdown releasing radiation into the surrounding area. The seemingly unhurried government reaction provided conflicting information to Japanese citizens, slowing evacuation and protective actions. Government failure is cited as a significant factor in the severity of the nuclear disaster in three investigations conducted after the incident. This article defines resilience and raises the question of whether the U.S. government has the ability to address the issues raised by the two case studies. There are four primary lessons of these two case studies from Japan: Trust is essential; two-way communications are vital; someone or something will always unexpectedly fail to act appropriately, while others will provide surprising support and; finally, recovery is long-term.

    Homelessness has frequently been associated with neuropsychological impairment. This has been observed using general screening tests for dementia as well as tests of more focal abilities, particularly executive function. Most studies have been of homeless individuals from North America with none reported from Japan. In this exploratory study we interviewed a sample of 16 homeless adults from Tokyo, Japan, and performed tests of cognitive function, assessed head injury, addictive behaviours (drug use, gambling, alcohol abuse), and recorded details of homelessness history. The cognitive examination involved the Japanese Adult Reading Test to estimate premorbid intelligence quotient, the Wisconsin Card Sorting Test to measure frontal lobe-related cognitive function, and the Mini-Mental State Examination to measure global cognitive impairment associated with dementia. Among the 16 homeless individuals, 7 (44%) displayed global cognitive impairment. In addition, executive function tended to be poor. In contrast, estimated premorbid intelligence quotient was within the normal range. Substance abuse in general was not at a level to cause clinical concern, although a high level of pathological gambling was observed. There were no associations between cognitive function and clinical and addictive behaviour variables, although associations were noted between cognitive scores and time spent homeless. The results suggest high levels of neuropsychological impairment in this sample of homeless adults in Japan. Furthermore, cognitive impairment is acquired rather than developmental in origin, and is proportional to the length of time spent homeless.

  7. Assessment of earthquake hazard in the Tokyo area, Japan

    1991-12-01

    The probability of occurrence of an inland earthquake originating beneath the Tokyo area is evaluated for a 10-year period from 1991. On the basis of an earthquake catalogue containing some 40 earthquakes, which caused some damage to Edo (now Tokyo) over a period of 400 years, the parameters of the Weibull and lognormal probability distributions applied to recurrence interval statistics are estimated. With these parameters, it is concluded that an earthquake directly beneath the capital, the magnitude of which is equal to or greater than 6.0, occurs with a probability of 0.40 for the period in question. When the magnitude threshold is assumed as 6.4 and 7.0, the probabilities become 0.17 and 0.049, respectively. These probability evaluations are extended to those for the seismic intensity at typical sites in the area, although no accurate evaluation is possible because the exact focal depths of historical earthquakes are not known. On the assumption that these earthquakes occur near the upper surface of the down-going Philippine Sea plate, however, a typical depth of 30 km or so is suggested. Should an earthquake having a mean magnitude of 6.4, say, and at a mean location of past earthquakes occur, the probability of seismic intensity at typical sites in the capital area exceeding 5 on the Japan Meteorological Agency (JMA) scale would amount to 0.17. The possibility of having a highly damaging earthquake of intensity 6 on the JMA scale also cannot be ruled out, judging from earthquake disasters in the past, although the probability does become lower. To summarize, it may be said that the probability of Japan's capital area being hit by a damaging earthquake in the foreseeable future is not particularly low.

    Nuclear engineering education has been initiated in 1957 at the graduate school of Tokyo Institute of Technology. Educational activities have been conducted for fifty years under the support of the Research Laboratory for Nuclear Reactors. In the past fifty years, about 1000 Master students and 200 Doctoral students and 200 Doctoral students graduated from our Nuclear Engineering Department at Tokyo Institute of Technology. Many of them found their jobs in nuclear industries and institutes. International course of nuclear engineering was initiated in 1994, and so far about 90 students from 15 overseas countries have graduated from our Master and Doctoral Programs. In 2003, our proposal of 'Innovative Nuclear Energy System for the Sustainable World' was adopted as the Center of Excellent Program sponsored by Ministry of Education, Science and Technology. Recently a collaborative education network has been developed among Kanazawa University, Fukui University, Ibaraki University, Okayama University, Tokyo Institute of Technology and Japan Atomic Energy Agency.

    Staphylococcus argenteus is a novel species subdivided from Staphylococcus aureus. Whether this species can cause food poisoning outbreaks is unknown. This study aimed to investigate the enterotoxigenic activities of two food poisoning isolates suspected to be S. argenteus (Tokyo13064 and Tokyo13069). The results for phylogenic trees, constructed via whole genome sequencing, demonstrated that both isolates were more similar to a type strain of S. argenteus (MSHR1132) than any S. aureus strain. Moreover, the representative characteristics of S. argenteus were present in both strains, namely both isolates belong to the CC75 lineage and both lack a crtOPQMN operon. Thus, both were determined to be "S. argenteus." The compositions of the two isolates' accessory elements differed from those of MSHR1132. For example, the seb-related Staphylococcus aureus pathogenicity island, SaPIishikawa11, was detected in Tokyo13064 and Tokyo13069 but not in MSHR1132. Both isolates were suggested to belong to distinct lineages that branched off from MSHR1132 lineages in terms of accessory elements. Tokyo13064 and Tokyo13069 expressed high levels of s(arg)eb and produced S(arg)EB protein, indicating that both have the ability to cause food poisoning. Our findings suggest that S. argenteus harboring particular accessory elements can cause staphylococcal diseases such as food poisoning, similarly to S. aureus. Copyright © 2017 Elsevier B.V.

    In order to solve the problem of the foreseeable depletion of fossil energy resources and of expected global climatic changes due to the emission of greenhouse gases future energy systems are required which meet the growing world energy demand but do not depend on fossil fuels. One possible option which is discussed as a clean and environmentally friendly energy source for the 21{sup st} century is the conversion of solar energy into hydrogen. Hydrogen as an environmentally friendly energy source can also be an integral part of a zero-emission economy because it can contribute to the minimization of toxic dispersion (especially the greenhouse gas CO{sub 2}) and to the maximization of sustainable use of renewable resources. It has been known for more than 50 years that certain living organisms are able to produce hydrogen. Biological hydrogen production has several comparative advantages over competing hydrogen production technologies such as photovoltaic or solarthermic electricity generation plus water hydrolysis. These advantages are - simpler systems: hydrogen production from direct water splitting without involvement of electricity/electrolysis, - self-regenerating systems, - biologically degradable systems: disposal can be coupled to the production of additional value-added substances, - flexible systems: production organisms can adapt to changing environmental conditions, - versatile systems: production organisms which are tailor-made to special environmental conditions can be selected.

    The aim of this study is to clarify the association between area-based social capital and suicide rate among municipalities of Tokyo. The study areas were 20 administrative municipalities of Tokyo. Social capital (i.e., organizational membership, social trust, fairness, helpfulness, and confidence in organizations) was measured based on data from a previous survey (response rate 28 %). Gender-specific age-adjusted suicide rates averaged over 5 years, sociodemographic, and other area characteristics were obtained from relevant national statistics. Multiple linear regression analysis of suicide rates was applied on each social capital variable, adjusting for the other area characteristics. There was no significant crude Pearson's correlation between any social capital variable and suicide rate. Multiple regression analyses revealed a significant negative association between social trust and suicide rate for men (p = 0.04). While based on only limited evidence from a cross-sectional ecological study, area-based social trust may be associated with decreased suicide rates for men in Tokyo.

    Perfluorooctane sulfonate (PFOS) was quantified in seawater and sediment samples collected from Tokyo Bay, Japan, ranging from 2.0 to 7.3 ng/L for surface seawater, 2.2 to 5.7 ng/L for intermediate seawater, 1.5 to 5.7 ng/L for bottom seawater, and 0.3 to 0.9 ng/g dry wt. for sediment. In addition, a 3-D chemical fate prediction model (National Institute of Advanced Industrial Science and Technology - Risk Assessment Model: AIST-RAM) has been applied to determine the accuracy of estimating PFOS in Tokyo Bay. A decreasing trend of PFOS from the northwestern part (i.e., the closed-off section of Tokyo Bay) to the mouth of the bay was observed, and the trend obtained from the actual surveys in this study was accurately represented by simulation with appropriate input parameters for AIST-RAM. From the comparison of observed concentrations with estimated concentrations, AIST-RAM showed a high degree of accuracy in estimating the concentrations of PFOS in seawater, whereas the estimations of PFOS concentrations in sediment had a relatively larger margin of error than those in seawater. However, our results indicate that AIST-RAM allows estimation of PFOS concentrations in seawater and sediment in Tokyo Bay with satisfactory accuracy.

    Urban green spaces play an important role in maintaining urban biodiversity in the Tokyo Metropolis, Japan. Plant-dependent insect assemblages such as Cerambycidae, in particular, are likely influenced by the existence of green spaces in Tokyo's urbanised environments. This study is the first comprehensive inventory of the cerambycid fauna in the Komaba Campus of the University of Tokyo. A cerambycid assemblage composed of a total of 25 species was recorded within the Komaba Campus site and compared to cerambycid assemblages in nine other green spaces distributed throughout Tokyo. The results indicated that the species number in the campus was similar to that recoded in a similar-sized green space in coastal Tokyo. Fewer cerambycid species were, however, found at the campus site than in larger-sized green spaces within Tokyo. Moreover, species compositions in urbanised areas were markedly different from those in suburbanised parks, mountains and forests within Tokyo.

    Full Text Available Introduction: A large rubella outbreak has been occurring in Tokyo, Japan since June 2012. Rubella vaccination, introduced in Japan in 1976, has targeted different age groups, resulting in a large proportion of the current population being unvaccinated. Methods: Rubella cases reported in Tokyo from 2 January 2012 to 21 April 2013 were analysed. A clinical case had generalized maculopapular rash, fever and lymphadenopathy; a laboratory-confirmed case was a clinical case with a positive serology or polymerase chain reaction test for rubella. A descriptive analysis of cases by age, sex, vaccination history and other epidemiological information was conducted. Results: A total of 2382 cases were reported from all areas of Tokyo. Three-quarters were male (n = 1823; 76.5%; the highest number of cases occurred among males aged 35–39 years and females aged 20–24 years. About a third of males (27% and females (32% reported never receiving rubella vaccination, with 68% and 56%, respectively, having an unknown vaccination status. Discussion: This outbreak reflects the changing, yet incomplete, immunization policies for rubella in Japan that may increase the risk of congenital rubella syndrome (CRS. To suppress the outbreak of rubella and prevent CRS cases, we recommend vaccination for the entire susceptible population.

    An outbreak of autochthonous dengue fever was reported in August 2014, with cases suspected mainly from Yoyogi Park in Tokyo. This is the first epidemic of dengue fever in Japan since 1945. From August to October 2014, the following measures were taken to control the outbreak: 1) risk communication and information sharing; 2) active case finding; 3) vector surveillance in affected sites; and 4) laboratory testing. We also reviewed the surveillance data as reported to the National Epidemiological Surveillance of Infectious Diseases during the 44 epidemiological weeks. results: An official dengue fever call center was set up temporarily for the general public and 3,005 calls were received. The Tokyo Metropolitan Government issued 39 press releases regarding patients and nine related to dengue virus (DENV) detection and vector control activities for the media. Confirmed autochthonous dengue fever cases were reported between the 35th and 44th epidemiological weeks. Out of 160 cases of outbreak, 108 (67.5%) confirmed cases were reported in Tokyo. The estimated illness onset dates were between August 9 and October 7, and estimated dates of infections were between August 3 and October 3, 2014. The data suggest that the infective mosquitoes had already been present in Yoyogi Park at the end of July 2014. During the weekly vector surveillance at Yoyogi Park, a total of 1,152 adult mosquitoes, of which 856 (73.3%) were Aedes mosquitoes, were collected over 11 weeks by a light trap with dry ice. DENV was detected from adult Aedes mosquito samples collected on the 2nd, 9th, and 16th of September, 2014. Serum samples from 240 suspected cases were examined at the Tokyo Metropolitan Institute of Public Health, and 78 were positive for the DENV NS1 antigen, DENV-specific IgM antibody, or DENV nucleic acid with reverse transcriptase polymerase chain reaction (RT-PCR) (NS1: 66 cases; IgM: 50 cases; PCR: 57 cases).

    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.

    In 2014 in Japan, 162 autochthonous dengue cases were reported for the first time in nearly 70 years. Here, we report the results of the detection and isolation of dengue virus (DENV) from mosquitoes collected in Tokyo Metropolis in 2014 and 2015. The phylogenetic relationship among DENV isolates from mosquitoes and from patients based on both the entire envelope gene and whole coding sequences was evaluated. Herein, 2,298 female and 956 male Aedes albopictus mosquitoes were collected at six suspected locations of DENV infection in Tokyo Metropolis from August to October in 2014 and grouped into 124 and 35 pools, respectively, for viral genome detection and DENV isolation. Dengue virus RNA was detected using reverse transcription polymerase chain reaction and TaqMan assays from 49 female pools; 16 isolates were obtained using C6/36 and Vero cells. High minimum infection rates (11.2-66.7) persisted until mid-September. All DENV isolates belonged to the genotype I in serotype 1 (DENV-1), and its sequences demonstrated > 99% homology to the sequence of the DENV isolated from a patient in the vicinity of Tokyo Metropolis in 2014. Therefore, Ae. albopictus was a major DENV vector, and a single DENV-1 strain circulated in Tokyo Metropolis in 2014. Dengue virus was not detected from male mosquitoes in 2014 and wild larvae in April 2015. Thus, the possibility of both vertical transmission and overwintering of DENV was extremely low, even in dengue-epidemic areas. This study reports the first entomological information on a dengue outbreak in a temperate region, where no Aedes aegypti mosquitoes are distributed.

    Abstract Background The Heteroptera, or true bugs, forms one of the major insect groups with respect to the very diverse habitat preferences, including both aquatic and terrestrial species, as well as a variety of feeding types. The first comprehensive inventory of the Heteroptera at Komaba Campus of the University of Tokyo, or an urban green space in the center of the Tokyo Metropolis, Japan, was conducted. New information A total of 115 species in 29 families of the suborder Heteroptera were identified. The area had a high species richness compared with other urbanized and suburbanized localities in Tokyo. The campus is found to show a substantial difference in heteropteran species compositions, despite being close to the other localities surrounded by highly urbanized zones in central Tokyo.

    A large rubella outbreak has been observed since June 2012 in Tokyo, Japan, and a rapid increase in the number of congenital rubella syndrome (CRS) cases have also been reported in Japan since October 2012. All the clinically diagnosed and laboratory-confirmed rubella cases reported in Tokyo from January 2012 to December 2013 and all the laboratory-confirmed CRS cases from January 2012 to March 2014 were analyzed. In total, 4,116 rubella cases were reported in Tokyo. Of these, 77.2% (n=3,176) were male; the highest number of cases occurred in males aged 35-39 years and in females aged 20-24 years. Complications included arthralgia/arthritis (19.4%), thrombocytopenic purpura (0.5%), hepatic dysfunction (0.3%), and encephalitis (0.1%). The circulating rubella virus in Tokyo was genotype 2B. The most possible site of transmission was the workplace. Because of the rubella epidemic, 16 CRS cases were reported in Tokyo from March 2013 to February 2014. Domestic infection with rubella was proven for all mothers of 16 cases. This situation suggests that Japan is still working to achieve rubella elimination.

  7. Prevalence of avian haemosporidia among injured wild birds in Tokyo and environs, Japan

    Full Text Available Avian haemosporidia have been reported in various birds of Japan, which is part of the East Asian-Australian flyway and is an important stopover site for migratory birds potentially carrying new pathogens from other areas. We investigated the prevalence of avian malaria in injured wild birds, rescued in Tokyo and surrounding areas. We also evaluated the effects of migration by examining the prevalence of avian malaria for each migratory status. 475 birds of 80 species were sampled from four facilities. All samples were examined for haemosporidian infection via nested polymerase chain reaction (PCR of the cytochrome b (cytb gene. 100 birds (21.1% of 43 species were PCR positive for avian haemosporidia. Prevalence in wintering birds, migratory breeders, and resident birds was 46.0%, 19.3%, 17.3% respectively. There was a bias in wintering birds due to Eurasian coot (Fulica atra and Anseriformes. In wintering birds, lineages which are likely to be transmitted by Culiseta sp. in Northern Japan and lineages from resident species of Northern Japan or continental Asia were found, suggesting that wintering birds are mainly infected at their breeding sites. Meanwhile, there were numerous lineages found from resident and migratory breeders, suggesting that they are transmitted in Japan, some possibly unique to Japan. Although there are limits in studying rescued birds, rehabilitation facilities make sampling of difficult-to-catch migratory species possible and also allow for long-term monitoring within areas.

    Annually, about 400 cases of sudden unexpected death are attributed to cancer in Tokyo, Japan. These individuals may have been undiagnosed, or their medical conditions may not have been carefully evaluated before death. We examined medical consultations, cancer diagnoses, and economic status of all cancer deaths investigated by medical examiners in 2009. Among cases handled by the Tokyo Medical Examiner's Office in 2009 (N = 12 493), records for all cases of cancer death (n = 400) were reviewed to determine the extent of medical care provided, diagnosis before death, and economic status of the decedent. Most of the decedents (n = 232; 58%) had received a diagnosis of terminal/advanced cancer during a medical consultation. Most did not receive such medical consultations at home, despite their very weak physical condition. However, nearly one quarter of decedents (24%; 95/400) had not received a cancer diagnosis before death. The proportions of decedents who had been indigent, received no medical consulting, and had colon cancer were significantly higher among undiagnosed cases than among diagnosed cases. Indigent persons were the largest subgroup (n = 19; 43%) among those who had never received a medical consultation (n = 44). In addition, the proportion of those who had discontinued or received no medical consultation was higher among indigent persons than among non-indigent persons. The quality of medical services for cancer patients could be improved by educating general practitioners about terminal care, expanding efforts to monitor and diagnose cancer, especially among indigent patients, and increasing participation rates for colorectal cancer screening.

    Perfluorinated compounds (PFCs) were detected in sediment core samples collected in Tokyo Bay to reveal their time trends. The core sample deposited during 1950s-2004 was divided into two- to three-year intervals and the concentrations of 24 types of PFCs were determined. Perfluorooctane sulfonate (PFOS) decreased gradually from the early 1990s and its precursor decreased rapidly in the late 1990s, whereas perfluorooctanoic acid (PFOA) increased rapidly. The observed trends were regarded as a reflection of the shift from perfluorooctyl sulfonyl fluoride (PFOSF)-based products to telomer-based products after the phaseout of PFOSF-based products in 2001. The branched isomers of perfluoroundecanoic acid (PFUnDA) and perfluorotridecanoic acid (PFTrDA) were detected in the sample with its ratio of linear-isomer/branched-isomer concentrations decreasing. In this study, we revealed that the sediment core can serve as a tool for reconstructing the past pollution trend of PFCs and can provide interesting evidence concerning their environmental dynamics and time trend. - This study reports the time trends of the concentrations of 24 species of PFCs, including FTCA, FTUCA and FOSAA, in a sediment core of Tokyo Bay, Japan.

    The hourly groundwater levels have been observed at 42 sites in Tokyo Metropolis since 1952. The Great East Japan Earthquake occurred at 14:46 JST on March 11, 2011. It was the strongest earthquake on record with a magnitude of 9.0 (Mw) and large fluctuations of unconfined and confined groundwater levels were observed at 102 observation wells in Tokyo, around 400 km away from the epicenter. Abrupt rises and sharp drawdowns of groundwater levels were observed right after the earthquake for most of the wells, although some did not show a change. In this study, taking full advantage of the unique rare case data from the dense groundwater monitoring network in Tokyo, we investigate the fluctuation patterns of unconfined and confined groundwater levels caused by the Great East Japan Earthquake. The groundwater level data used in this study consist of one month time series in March 2011 with one-hour interval. The fluctuation patterns of groundwater levels caused by the earthquake were identified using Self-Organizing Maps (SOM). The SOM, developed by Kohonen, can project high-dimensional, complex target data onto a two-dimensional regularly arranged map in proportion to the degree of properties. In general, the objective of the SOM application is to obtain useful and informative reference vectors. These vectors can be acquired after iterative updates through the training of the SOM. Design of the SOM structure, selection of a proper initialization method, and data transformation methods were carried out in the SOM application process. The reference vectors obtained from the SOM application were fine-tuned using cluster analysis methods. The optimal number of clusters was selected by the Davies-Bouldin index (DBI) using the k-means algorithm. Using the optimal number of cluster, a final fine-tuning cluster analysis was carried out by Ward's method. As a result, the fluctuation patterns of the confined and unconfined groundwater level were classified into eight clusters

    The early modern Edo period in Japan refers to the division of chronological age dated from the seventeenth to nineteenth centuries. During that period, the social structure was stratified, with warriors at the top, followed by farmers, and finally townsmen at the bottom. I aimed to examine carious lesions in deciduous teeth in the commoners from the city of Edo (now Tokyo), to compare them with those in the warriors and commoners from Kyushu, and to reveal differences in the incidence of caries across social classes and regions. I examined 843 deciduous teeth of 115 individuals from the Hitotsubashi site in Tokyo. The comparative samples were obtained from warriors and commoners whose remains were excavated from the Sougenji and Kyoumachi sites, respectively, in Kyushu [Oyamada et al. (2008) Anthropol Sci 116:9-15]. The caries frequency in the Hitotsubashi sample was 11.3 %. Carious lesions in the upper teeth were more frequent than those in the lower teeth in all age groups. The upper incisors exhibited the highest frequency of caries, while there was almost no caries in the lower incisors and canines. I also found population differences in deciduous caries among the Edo populations. Remains of teeth excavated from Hitotsubashi were found to have a mild degree of caries compared to remains of teeth excavated from Sougenji and Kyoumachi in Kyushu in terms of caries frequency and location. Thus, the influence of regional differences in diet and living circumstances was stronger than expected, and the variation observed in the frequency of deciduous caries among the Edo populations cannot be explained by social class alone.

    Joint research committees in purpose of the discussion on DEMO blanket in view point of the both of reactor technology and materials were held by the Research Committee for Fusion Reactor and Fusion Materials. The joint research committee was held in Tokyo on July 12, 2002. In the committee, the present status of development of solid and liquid breeding blanket, the present status of development of reduced activation structure materials, and IFMIF (International Fusion Materials Irradiation Facility) program were discussed based on the discussions of the development programs of the blanket and materials at the first joint research committee. As a result, it was confirmed that high electric efficiency with 41% would be obtained in the solid breeding blanket system, that neutron radiation data of reduced activation ferritic steel was obtained by HFIR collaboration, and that KEP (key element technology phase) of IFMIF would be finished at the end of 2002 and the data base for the next step, i.e. EVEDA (engineering validation/engineering design activity) was obtained. In addition, the present status of ITER CTA, which was a transient phase for the construction, and the outline of ITER Fast Track, which was an accelerated plan for the performance of the power plants, were reported. This report consists of the summary of the discussion and the viewgraphs which were used at the second joint research committee, and these are very useful for the researchers of the fusion area in Japan.

    Enterotoxigenic Escherichia coli (ETEC) caused 131 outbreaks in Tokyo, Japan, between 1966 and 2009. The major serogroups were O6, O27, O148, and O159. The incidence of serogroups O25 and O169 recently increased. Heat-stable enterotoxin (ST) subtyping revealed that E. coli of serogroups O6, O15, O25, and O159 possessed the STh gene, whereas those serotyped as O27 and O169 possessed the STp gene.

    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

    This special issue of Journal of Physics: Condensed Matter comprises selected papers from the proceedings of the 2nd International Conference on Quantum Simulators and Design (QSD2008) held in Tokyo, Japan, between 31 May and 3 June 2008. This conference was organized under the auspices of the Development of New Quantum Simulators and Quantum Design Grant-in-Aid for Scientific Research on Priority Areas, Ministry of Education, Culture, Sports, Science and Technology of Japan (MEXT). The conference focused on the development of first principles electronic structure calculations and their applications. The aim was to provide an opportunity for discussion on the progress in computational materials design and, in particular, the development of quantum simulators and quantum design. Computational materials design is a computational approach to the development of new materials. The essential ingredient is the use of quantum simulators to design a material that meets a given specification of properties and functionalities. For this to be successful, the quantum simulator should be very reliable and be applicable to systems of realistic size. During the conference, new methods of quantum simulation and quantum design were discussed including methods beyond the local density approximation of density functional theory, order-N methods, methods dealing with excitations and reactions, and the application of these methods to the design of novel materials, devices and systems. The conference provided an international forum for experimental and theoretical researchers to exchange ideas. A total of 220 delegates from eight countries participated in the conference. There were 13 invited talks, ten oral presentations and 120 posters. The 3rd International Conference on Quantum Simulators and Design will be held in Germany in the autumn of 2011.

    Long-period ground motions due to large earthquakes can cause devastating disasters, especially in urbanized areas located on sedimentary basins. To assess and mitigate such damage, it is essential to rapidly evaluate seismic hazards for infrastructures, which can be simulated by seismic response analyses that use waveforms at the base of each infrastructure as an input ground motion. The present study reconstructs the seismic wavefield in the Tokyo metropolitan area located on the Kanto sedimentary basin, Japan, from seismograms of the Metropolitan Seismic Observation network (MeSO-net). The obtained wavefield fully explains the observed waveforms in the frequency band of 0.10-0.20 Hz. This is attributed to the seismic wavefield imaging technique proposed by Kano et al. (2017), which implements the replica exchange Monte Carlo method to simultaneously estimate model parameters related to the subsurface structure and source information. Further investigation shows that the reconstructed seismic wavefield lower than 0.30 Hz is of high quality in terms of variance reduction (VR), which quantifies a misfit in waveforms but that the VR rapidly worsens in higher frequencies. Meanwhile, the velocity response spectra show good agreement with observations up to 0.90 Hz in terms of the combined goodness of fit (CGOF), which is a measure of misfit in the velocity response spectra. Inputting the reconstructed wavefield into seismic response analyses, we can rapidly assess the overall damage to infrastructures immediately after a large earthquake.

    In order to make clear the impact of air pollution on the formation of sudden and locally-distributed heavy rain in urban area (hereafter Urban Heavy Rain: UHR), we analyzed inorganic ion concentration and stable isotope ratio of water (δD and δ18O) in rainwater. Rainwater samples were collected in Shinjuku, which is a representative downtown of Tokyo, Japan, during four years from October 2012 to December 2015. The concentration and wet deposition fluxes of acidic components (H+, NH4+, NO3-, and nss-SO42 -) in UHR were especially higher than those in other types of rain events, i.e. normal rain, typhoon heavy rain, and frontal heavy rain. UHR had distinctly lower stable isotope ratios than those in other urban rains with same rainfall amount and summer precipitation systems. There was a high negative correlation between δ18O and the distances from the sampling point to the formation area of UHR within 10 km, while there were high positive correlations between δ18O and the concentration of acidic components in UHR. These findings indicate that UHR could effectively scavenge acidic substances within cloud and suggest the use of stable isotope ratios as tracers of an urban heavy rain's water and in-cloud scavenging process.

    The contamination, distribution and pathogenicity of Toxocara canis and T. cati eggs in sandpits in the Tokyo metropolitan area, Japan, are described. A total of 34 sandpits were examined, 14 of which were contaminated with T. cati eggs, as assessed by the floatation method and polymerase chain reaction (PCR) analysis. Two naturally contaminated sandpits were investigated to determine the vertical and horizontal distribution of eggs, and an inverse relationship between the sand depth and number of eggs was observed. To examine the pathogenicity of the eggs, three ICR mice were inoculated with 300 eggs, which were recovered from sandpits. The mice exhibited eosinophilia in the peripheral blood and IgG antibody production in the sera after 3 weeks of infection. Most migrating larvae were recovered from carcasses, although three were found in the brains of two infected mice. These three larvae were determined to be T. canis by PCR, revealing that not only T. cati, but also T. canis eggs could be found in sandpits and, further, that eggs recovered from sandpits have the ability to invade a paratenic host.

    The first domestic outbreak of dengue fever in Japan since 1945 was reported in Tokyo in 2014. Meanwhile, daily mean summer temperatures are expected to continue to rise world-wide. Such conditions are expected to increase the risk of an arbovirus outbreak at the 2020 Tokyo Olympic Games. To address this possibility, the present study compared estimates of the risk of infection by dengue, chikungunya, and Zika viruses in urban areas. To compare the risk of infection by arboviruses transmitted by Ae. albopictus mosquitoes, the reproduction number for each of three arboviruses was estimated under the environmental conditions associated with the 2014 dengue outbreak in Tokyo, and additionally under conditions assuming a daily mean temperature elevation of 2° C. For dengue, chikungunya, and Zika, the estimated distributions of R 0 were independently fitted to gamma distributions yielding median R 0 values of 1.00, 0.46, and 0.36, respectively. If the daily mean temperature were to rise from 28° C to 30° C, our model predicts increases of the median R 0 of 18% for dengue, 4.3% for chikungunya, and 11.1% for Zika. Strengthening of the public health responsivity for these emerging arboviral diseases will be needed in preparation for the 2020 Olympic Games in Tokyo.

    Caffeine is widely available in beverages and over-the-counter products; however, in large doses, it can lead to lethal arrhythmia. This study aims to clarify the characteristics of caffeine intoxication-related deaths in Tokyo, Japan. Among the 4754 forensic autopsy cases between 2008 and 2013 in which a toxicological investigation was performed, cases in which the blood concentration of caffeine exceeded toxic levels (15 μg/ml) were selected (N = 22). We examined subjects' ages, medical histories, direct/underlying causes of death, and manner of death. We also assessed concurrent drug substance detection and identified the origin of the caffeine. More than 60% of the subjects were between the ages of 20 and 49 years (n = 14, 63.6%). Sixteen cases (72.7%) showed a history of psychiatric diseases such as depression and sleep disorders. The underlying cause of death for all cases except two was caffeine intoxication, and manner of death was classified as undetermined (n = 11), accidental (n = 7), suicide (n = 2), or others (n = 2). Toxicological analysis revealed the presence of ingredients common to analgesics/cold remedies in 12 cases (54.5%). The origin of the caffeine was identified in 11 cases (50.0%); the proportion of identification was significantly lower among the cases in which analgesic/cold remedy ingredients were not detected (20.0%). Caffeine intoxication-related deaths mainly occurred in young and middle-aged persons with common psychiatric diseases. Psychiatrists should take note of caffeine dependence while diagnosing common psychiatric symptoms. In half of the cases, the origin of the caffeine was unidentified; nevertheless, dietary sources or over-the-counter drugs containing caffeine were suspected. As it becomes easier to obtain caffeinated products, continuous monitoring of the number of deaths from caffeine intoxication, in addition to detailed investigations of the caffeine's origin, will be necessary.

    Background Sudden bath-related deaths occur frequently in Japan, particularly among elderly people. However, the precise mechanism of bath-related death remains uncertain, and effective prevention strategies have not been established. Methods Cases of bath-related deaths (n = 3289) were selected from all cases handled by the Tokyo Medical Examiner’s Office from 2009 to 2011 (N = 41 336). The ages and occurrence dates were examined, and major autopsy findings, including toxicological analysis, were evaluated for the autopsied cases (n = 550). Results Most cases occurred in individuals older than 60 years of age during winter. Analysis of autopsy findings revealed water inhalation signs in many cases (n = 435, 79.1%). Circulatory system diseases constituted more than half of the pathological findings regarding factors that may have contributed significantly to death (n = 300, 54.5%), and cardiac lesions were the most common pathological finding (n = 250, 45.5%). However, approximately one-third of the cases exhibited no remarkable pathological findings (n = 198, 36.0%). A quarter of all cases involved blood ethanol levels that exceeded 0.5 mg/mL (n = 140). Conclusions The results suggested that drowning plays an important role in the final process of bath-related death. Circulatory system diseases may be the primary underlying pathology; however, there were variations in the medical histories and pathologies of cases of bath-related death. From a preventive perspective, family members should pay attention to elderly people with circulatory system diseases during bathing, particularly in winter. Additionally, the notion that ill or inebriated individuals should not take baths should be reinforced. PMID:25503827

    Full Text Available Background: Although the control of varicella outbreaks is an important health issue, cost could present a major barrier for vaccination The aim of this study is to investigate the association of vaccine subsidies and caregivers’ socioeconomic status with varicella vaccine coverage of their children in Greater Tokyo, Japan, before the period that varicella vaccination was included as routine immunization program.Methods: Participants were recruited from two different cities. In Chiba city, parents of 18-month-old infants (N = 378 undergoing a medical examination in July 2013 were recruited at a clinic where no subsidy for varicella immunization was provided. In Nishitokyo city, parents of 24- to 30-month-old children (N=315 undergoing a health check-up in July and August 2013 were recruited at a clinic where a partial subsidy was provided. The association between household income and varicella immunization was investigated by multivariate logistic regression stratified by city.Results: Vaccine coverage was 61.0% in Chiba city and 73.3% in Nishitokyo city. In Chiba city, odds ratios of middle and high household income for varicella immunization were 4.22 (95% CI (confidence interval: 1.65-10.7 and 5.94 (95% CI: 1.89-18.6 compared to low household income, respectively. However, household income was not associated with varicella vaccination in Nishitokyo city. Neither working status nor education was associated with vaccination in both cities. Conclusions: While household income was associated with high vaccine coverage in the city with no vaccine subsidy, this association was not observed in the city where the subsidy was given, which suggests that cost is a barrier for varicella immunization.Thus, in countries where varicella vaccination is not included in routine immunization program, introducing subsidies nationwide or routine immunization programs for varicella vaccination would be an important approach to eliminate inequality in vaccine

    There has been increasing interest in the formal review of child deaths in Japan. In this study we examined the causes and scene information regarding child deaths from injury in Tokyo, the capital of Japan, as preparation for implementation of a full-scale review of child deaths. Documents on deaths from injury (excluding homicides) investigated by the Tokyo Medical Examiner's Office during the period from 2006 through 2010 were reviewed. Deaths of children younger than 18 years (N = 217) were selected as the study sample. We examined the cause of and information on the death and were particularly interested in whether a case had preventable factors. Overall, 67% of the cases were deaths from unintentional injury. The main cause of death among children younger than 1 year was asphyxia, and the proportions of deaths from traffic accidents were higher in older age groups. Thirty percent of deaths from injury were due to suicide, and all cases of suicide were among children older than 10 years. Although analysis of preventable factors was difficult in some cases, owing to limited information on the death scene, 87% of deaths from unintentional injury, excluding those involving traffic accidents, had preventable factors. Most unintentional child deaths from injury appear to be preventable. Development of a system to collect detailed information on the scene at the time of death will help decrease child deaths in Japan.

    Full text: A team of international nuclear safety experts today completed a review of Japan's two-stage process for assessing nuclear safety at the nation's nuclear power plants. The team began its work on 23 January and delivered a Preliminary Summary Report to Japanese officials today and plans to finish the final report by the end of February. National safety assessments and their peer review by the IAEA are a key component of the IAEA's Action Plan on Nuclear Safety, which was approved by the Agency's 152 Member States following last year's nuclear accident at Fukushima Daiichi Nuclear Power Station. At the request of the Government of Japan, the International Atomic Energy Agency (IAEA) organized a 10-person team to review the Japanese Nuclear and Industrial Safety Agency's (NISA) approach to the Comprehensive Assessments for the Safety of Existing Power Reactor Facilities and how NISA examines the results submitted by nuclear operators. The IAEA safety review mission consisted of five IAEA and three international nuclear safety experts. To help its review, the team held meetings in Tokyo with officials from NISA, the Japanese Nuclear Energy Safety (JNES) Organization, and the Kansai Electric Power Company (KEPCO), and the team visited the Ohi Nuclear Power Station to see an example of how Japan's Comprehensive Safety Assessment is being implemented by nuclear operators. 'We concluded that NISA's instructions to power plants and its review process for the Comprehensive Safety Assessments are generally consistent with IAEA Safety Standards', said team leader James Lyons, director of the IAEA's Nuclear Installation Safety Division. In its Preliminary Summary Report delivered today, the team highlighted a number of good practices and identified some improvements that would enhance the overall effectiveness of the Comprehensive Safety Assessment process. Good practices identified by the mission team include: Based on NISA instructions and commitments of the

    Suspended particulate matter (SPM) and fine particulate matter (less than or equal to 2.5 microm: PM2.5) have generally been decreasing for the last decade in Tokyo, Japan. To elucidate the major cause of this decrease, the authors investigated the different trends of airborne particulates (both SPM and PM2.5 concentrations) by evaluating comparisons based on the location of the monitoring stations (roadside vs. ambient), days of the week (weekdays vs. Sundays), and daily fluctuation patterns (2002 vs. 2010). Hourly mean SPM and PM2.5 concentrations were obtained at four monitoring stations (two roadside stations, two ambient stations) in Tokyo, Japan. Annual mean concentrations of each day of the week and of each hour of the day from 2002 to 2010 were calculated. The results showed that (1) the daily differences in annual mean concentration decreased only at the two roadside monitoring stations; (2) the high hourly mean concentrations observed on weekdays during the daily rush hour at the two roadside monitoring stations observed in 2002 diminished in 2010; (3) the SPM concentration that decreased the most since 2002 was the PM2.5 concentration; and (4) the fluctuation of hourly concentrations during weekdays at the two roadside monitoring stations decreased. A decreasing trend of airborne particulates during the daily rush hour in Tokyo, Japan, was observed at the roadside monitoring stations on weekdays since 2002. The decreasing PM2.5 concentration resulted in this decreasing trend of airborne particulate concentrations during the daily rush hours on weekdays, which indicates fewer emissions were produced by diesel vehicles. Implications: The authors compared the trends of SPM and PM2.5 in Tokyo by location (roadside vs. ambient), days of the week (weekdays vs. Sundays), and daily fluctuation patterns (2002 vs. 2010). The high hourly mean concentrations observed at the roadside location during rush hour on weekdays in 2002 diminished in 2010. The SPM

    The Academy for Global Nuclear Safety and Security Agent was established at Tokyo Institute of Technology in 2011, to develop global nuclear human resources in the field of 3S (Safety, Security, and Safeguards) as a Program for Leading Graduate Schools supported by MEXT (Ministry of Education, Culture, Sports, Science and Technology). New courses of nuclear safety and security were developed in addition to the existing nuclear engineering program; 1) Environmental Dynamics of Radioactive Nuclides; Numerical simulation of the environmental dispersion of radioactive materials released from hypothetical nuclear accidents and evaluation of the public exposure are performed, by using a computer-based emergency response system, to have students predict the environmental dispersion of radionuclides and radiological consequence by nuclear accidents. 2) Measurement of Environmental Radiation; Students acquire hands-on experiences measuring environmental radiation contamination caused by the nuclear accident in Fukushima with multiple types of radiation detectors. Environmental samples are collected and analyzed for isotope identification and its spatial distribution. 3) Simulation of Severe Nuclear Accidents; The evaluation results of Fukushima accident progression are discussed as well as typical sever accidents that threaten the integrity of reactor vessel. Students simulate BWR (Boiling Water Cooled Reactor) transients, design basis accidents, and severe accidents by using simulators. 4) Nuclear Security Training; Design of physical protection systems, its fundamental physics, and regulatory frameworks are covered and students gain the practical experiences by use of intrusion detection systems at JAEA (Japan Atomic Energy Agency), and by numerical simulation of hydro-dynamics of structure material and nuclear material criticality at the university.

    Atmospheric fallout samples collected from Tokyo between 1963 and 2003 were analyzed using accelerator mass spectrometry (AMS) in order to determine (129)I/(127)I ratios and to examine the deposition rate of (129)I and its secular variation in Tokyo. The (129)I/(127)I ratios in the atmosphere during 1963-1977 ranged from 1 × 10(-8) to 2 × 10(-8). This is roughly 4 orders of magnitude higher than pre-atomic levels, possibly due to atmospheric nuclear weapons tests. The calculated monthly atmospheric deposition rates of (129)I differed from those produced by nuclear fallout of (90)Sr and (137)Cs, indicating that the variations in (129)I deposition are not influenced exclusively by either nuclear bomb testing or by the Chernobyl accident. After 1978, high (129)I depositions (up to 0.13 mBq/m(2)/month) were observed. The (129)I depositions started to increase markedly at the latter half of the 1970s. The secular variation of the estimated annual (129)I deposition in Tokyo showed a close relationship between the annual atmospheric discharge of (129)I from the Tokai Reprocessing plant. Therefore, the atmospheric fallout collected from Tokyo after the late 1970s is influenced primary by the (129)I discharge from the Tokai Reprocessing plant. Copyright © 2012.

    Nitrogen oxides (NOx = NO + NO2) are anthropogenically emitted as a form of NO in the high-temperature burning processes of fossil fuels mainly in energy generations and vehicles. Because NOx is a precursor of ozone, which is composed of a so-called photochemical smog, and is a health-hazard matter, the monitoring of NO2 is important to control air quality. The satellite observation is one of the most suitable methods for the monitoring of air pollution because satellite observations can obtain a global distribution of the pollutants. However, the observation of tropospheric gases by satellites still includes technically challenging problems, and the field is developing. To test whether satellite observations could successfully detect the behavior of tropospheric NO2, we compared satellite and ground-based observations of tropospheric NO2 over the Tokyo region. The satellite data were tropospheric NO2 vertical column density (VCD) derived from Global Ozone Monitoring Experiment (GOME) spectrometer measurements (hereafter GOME-NO2) [Richter et al., 2005], and the ground-based data were surface NO2 volume mixing ratio (VMR) observed by the network of air-quality monitoring stations in Tokyo. The analysis was performed for the data from January 1996 to June 2003. We found a strong correlation between GOME-NO2 and the surface VMR. They showed a similar seasonal variation with a maximum in winter and a minimum in summer. The result suggested that GOME was observing the behavior of NO2 near the surface in the Tokyo region. A more rigorous comparison was conducted by scaling the surface NO2 VMR to the tropospheric VCD with vertical NO2 VMR profiles. The NO2 profiles were calculated by using the chemical transport model CMAQ/REAS [Uno et al., 2007; Ohara et al., 2007]. This second comparison indicated that the GOME observations represent the behavior of NO2 more closely at the relatively unpolluted ground stations than at the highly polluted ground stations of the air

    Full Text Available Background: The Domain-Specific Risk Taking scale (DOSPERT has been used to measure risk perceptions and attitudes in several nations and cultures. Takahashi translated DOSPERT to Japanese but DOSPERT responses from Japan have never been reported. Butler et al. (2012 developed an additional medical risk domain subscale to be added to DOSPERT to form DOSPERT+M. Objective: To describe the translation of the medical risk domain subscale to Japanese and to characterize domain-specific risk attitudes in Tokyo. Methods: Members of a probability-weighted online panel representative of the Tokyo metro area were randomized to complete pairs of DOSPERT+M tasks (risk attitude, risk perception, benefit perception. We explored relationships among domains through correlational and factor analysis; we tested the hypothesis that the medical risk domain and DOSPERT's health/safety domains were uncorrelated. Participants: One hundred eighty panelists. Results: Six of the original DOSPERT items (two each in the ethics, health/safety, and financial domains are not useable in Japan according to the Japanese Marketing Research Association code because they ask about participation in illegal activities; we thus used abbreviated versions of those domains leaving out these items. The DOSPERT+M items generally did not cluster cleanly into the expected domains, although items within the same domain usually were intercorrelated. Participants demonstrated domain-specific conventional risk attitudes, although nearly half of those assessed were perceived-risk neutral in all domains. Unlike our recently reported findings in the U.S. population, DOSPERT+M medical domain scores were associated with health/safety domain scores, although they were often more strongly associated with scores in other domains, such as recreational activities. Conclusion: The DOSPERT (and DOSPERT+M instruments are problematic in Japan but Japanese citizens may also differ from those of other nations

    We surveyed prevalence and contamination levels of Listeria monocytogenes in ready-to-eat foods between 2000 and 2012 in Tokyo. L. monocytogenes was isolated from 52 (1.7%) out of 2,980 samples. Comparing the prevalence in the study period, 2.2% were positive in the former period (2000-2005) and 1.2% in the latter (2006-2012). Using the most probable number (MPN) technique, 32 samples were contaminated with fewer than 0.3 L. monocytogenes/g, 10 samples with 0.3-1.0/g and 4 samples with more than 1.0/g (the maximum was 2.3/g). The most common serovar was 1/2a, followed by 1/2b, 4b and 1/2c. We revealed that ready-to-eat foods in Tokyo were contaminated with L. monocytogenes, although the contamination levels were low.

    On 11 March 2011, the eastern part of Japan was struck by a magnitude 9.0 quake. About 20 000 people were killed or were missing, and a nuclear crisis followed. In Tokyo, people were indirectly exposed to the earthquake and nuclear crisis by TV broadcast. The aim of our study was to evaluate the potential effect of the series of catastrophes on psychiatric emergency hospitalizations in Tokyo. Clinical records of patients who were mandatorily admitted to Tokyo Metropolitan Matsuzawa Hospital by law because of urgent risk to self or others were reviewed. Records regarding the 2 years of investigation, which include the 6 months after the earthquake, were reviewed. The six months after the earthquake were compared with the eighteen months before the earthquake in clinical and demographic data using independent t-tests or χ(2) tests. During the 6 months before and after the earthquake, 97 and 127 people were mandatorily admitted. χ(2) Tests demonstrated a significant increase in the number of patients after the earthquake (P = 0.045), attributable to the significant increase in the number of patients with schizophrenia after the earthquake (P = 0.011, 32 vs 56), whereas there were no significant differences in the number of patients with other diagnoses between those two periods. Independent t-tests revealed that patients admitted after the earthquake had marginally significantly shorter periods of education compared with those admitted before the earthquake (13.78 vs 12.82 years, P = 0.084). This work suggests that patients with schizophrenia were more sensitive to indirect exposure to the earthquake and that a shorter period of education was a potential risk factor.

    The changes in March mean temperatures in Edo (Tokyo), Japan, since the seventeenth century, were reconstructed using phenological data for the cherry blossoms of Prunus jamasakura deduced from old diaries and chronicles. The observations of the time of full blossoming and of cherry blossom viewing parties were acquired and used to construct a full-blossoming phenological data series for P. jamasakura. Phenological data from 207 of the years from 1601 to 1905 were used for this study. The reconstructed temperatures suggested the existence of two cold periods (the second half of the seventeenth century and the beginning of the nineteenth century), during which times the estimated March mean temperatures were about 4 °C and 5 °C, respectively. These two cold periods at Edo coincided with those reconstructed at Kyoto in previous studies. These cold periods coincided with two less extreme periods, the Maunder and Dalton minima, in the long-term solar variation cycle.

    Full Text Available Urban agriculture can enhance the resilience of neighborhoods by providing fresh food in times of natural disasters; however, there is little empirical evidence to support this. Therefore, this study proposes a methodology to identify patterns of agricultural production in urban areas by quantifying self-sufficiency rates in vegetable weight and key nutrients. A spatial grid cell analysis using a geographic information system (GIS identifies the current and potential self-sufficiency of each land use pattern in Tokyo. In a total of 1479 grid cells, the dominant land use and locations of 49,263 agricultural plots led to the categorization of six distinguishable land use patterns. The results showed that Tokyo has a fruit and vegetable self-sufficiency of 4.27% and a potential of 11.73%. The nutritional self-sufficiency of selected nutrients was the highest in vitamin K (6.54%, followed by vitamin C (3.84% and vitamin A (1.92%. Peri-urban areas showed the highest resilience in relation to aggregated risks and population density because of the mixture in agricultural and urban land uses.

    We report present status of a beam line for transportation of highly charged ions (HCIs) extracted from the Tokyo EBIT. We have produced continuous beams of 2.5 x 10 5 cps for Xe 44+ through a 1 mm aperture. With slightly high energy operation (electron beam energy: 78 keV) of the Tokyo EBIT, we have also obtained 10 3 ions/pulse for Ta 70+ HCIs extracted by a pulse mode (trapping time: 3 sec). We are going to apply such HCI beams to nano-processes on solid surfaces by utilizing some useful characteristics of the HCI-interactions. Future perspective of HCI-based nano-science and -technology is presented

    The last time I had the pleasure of speaking to the Foreign Correspondents' Club of Japan was in December 2010. I had been IAEA Director General for about a year. Three months later came the Fukushima Daiichi accident. It was triggered by a powerful tsunami which followed the Great East Japan Earthquake. Human and organizational failings also played a part. Helping Japan deal with the aftermath of the accident has been a top priority for the IAEA, and for me personally, in the past three years. Nuclear safety is a hugely important issue, both in Japan and throughout the world. We have been working with our 162 Member States to implement the IAEA Action Plan on Nuclear Safety, which was adopted soon after the accident. Just recently, the final reports of our international review missions on decommissioning, and on remediation of large contaminated off-site areas, were made public. Both missions observed good progress in their respective areas. The IAEA is preparing a report on the Fukushima Daiichi accident, which will be finalized by the end of this year and shared with our Member States next year. I welcome the way in which Japan is sharing its post-Fukushima experience with the rest of the world and I encourage all States to make full use of IAEA services in order to help raise levels of safety everywhere

  2. Associations of acute exposure to fine and coarse particulate matter and mortality among older people in Tokyo, Japan.

    Recent studies have reported adverse health effects of short-term exposure to coarse particles independent of particulate matter less than 2.5 μm in diameter (PM2.5), but evidence in Asian countries is limited. We therefore evaluated associations between short-term exposure to particulate matter (PM) and mortality among older people in Tokyo, Japan. We used a time-stratified, case-crossover design. Study participants included 664,509 older people (≥65 years old) in the 23 urbanized wards of the Tokyo Metropolitan Government, who died between January 2002 and December 2013. We obtained PM2.5 and suspended particulate matter (SPM; PM<7 μm in diameter) from one general monitoring station. We calculated PM7-2.5 by subtracting PM2.5 from SPM to account for coarse particles. We then used conditional logistic regression to estimate odds ratios (ORs) and 95 confidence intervals (CIs). Same-day PM2.5 and PM7-2.5 were independently associated with all-cause and cause-specific mortality related to cardiovascular and respiratory diseases; for example, both pollutants were positively associated with increased risk of all-cause mortality even after simultaneous adjustment for each pollutant: OR of 1.006 (95% CI: 1.003, 1.009) for PM2.5 and 1.016 (95% CI: 1.011, 1.022) for PM7-2.5. Even below concentrations stipulated by the Japanese air quality guidelines for PM2.5 and SPM (PM7), we observed adverse health effects. This study provides further evidence that acute exposure to PM2.5 and coarse particles is associated with increased risk of mortality among older people. Rigorous evaluation of air quality guidelines for daily average PM2.5 and larger particles should be continued. Copyright © 2015 Elsevier B.V. All rights reserved.

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

    Toxic risks of sediments collected from seven sites in Tokyo Bay were evaluated using Japanese medaka embryos. Those sediments with slight pore water were placed in grass petri dishes without overlying water. The most remarkable effect in the field sediment was to cause hatching delay in embryos, and the longest time until hatching took was 12.5 ± 1.6 days post-fertilization (dpf), although that in control group was 10.1 ± 0.7 dpf. A significant delay in hatching was observed at four sites. Because total carbon concentrations were relatively high in sediments at three of these four sites, several chemicals were expected to be residues in these sites and could cause their delay. Although extreme mortality was not observed at all sites, sediments collected from the site close to Kawasaki city induced 10 % mortality. Polycyclic aromatic hydrocarbon (PAH) concentrations were remarkably high at this site compared with other sites, and thus PAH toxicities could be causing the mortality. Concentration of heavy metals such as cadmium, copper, lead, and zinc in sediments were also determined, but no clear relationship was found between toxicities to embryos and the distribution of their concentrations.

    Social welfare and public health departments require reliable assessments to enhance the rationality of phased construction of special elderly nursing homes (SENHs). This paper aims to assess the allocation of SENHs based on a beds-needed index for SENHs (BNIS). This may help departments determine the priority for approving locations of SENHs more accurately with a limited budget. Traditional assessments in Tokyo use the sphere of welfare, ward, and sphere of daily life as spatial units for estimating beds-to-elderly population ratios. We calculate the BNIS by introducing a parameter-improved floating catchment area method (PI-FCA) at a smaller spatial unit, the Chome. In the PI-FCA, the catchment area is generated according to the standard of average population served by SENHs and capacity, the population demand is the population of the elderly requiring care levels 3-5 and is further modified by a coefficient of potential demand via building a multivariate linear model. Improved results were obtained using the PI-FCA. Finally, this study maps the distribution of the degree of BNIS, to provide a basis for the allocation assessment of SENHs. This caters to the needs of departments and is easily applicable in other public healthcare facilities.

    Congenital adrenal hyperplasia (CAH) cause life-threatening adrenal crisis. It also affects fetal sex development and can result in incorrect sex assignment at birth. In 1989, a newborn screening program for congenital adrenal hyperplasia (CAH) was introduced in Tokyo. Here we present the results of this screening program in order to clarify the efficiency of CAH screening and the incidence of CAH in Japan. From 1989 to 2013, a total of 2,105,108 infants were screened for CAH. The cutoff level for diagnosis of CAH was adjusted for gestational age and birth weight. A total of 410 infants were judged positive, and of these, 106 patients were diagnosed with CAH, indicating a positive predictive value (PPV) of 25.8 %. Of the 106 patients, 94 (88.7 %) were diagnosed with 21-OHD. Of these 94 patients, 73 were diagnosed with the salt wasting form, 14 with the simple virilising form and 7 with the nonclassical form (NC21OHD). The mean birth weight and gestational age were 3192 ± 385 g and 38.9 ± 1.38 weeks. 11 out of 44 female patients were assigned as female according to their screening result. These data suggest that the newborn screening in Tokyo was effective, especially for sex assignment and preventing fatal adrenal crisis. The incidence of CAH was similar to that measured in previous Japanese screening studies, and it was also similar to that of western countries. The incidence of NC21OHD in Japan in the present study was lower than that in western countries as previous studies reported. The screening program achieved higher PPV than previous CAH screening studies, which might be due to the use of variable cutoffs according to gestational age and birth weight. However, most of the neonates born at 37 weeks or less that were referred to hospital were false-positives. Further changes are needed to reduce the number of false positive preterm neonates.

    Benzo[a]pyrene (BaP) is one of the polycyclic aromatic hydrocarbons, and has serious detrimental effects on human health and aquatic environments. In this study, we isolated nine bacterial strains capable of degrading BaP from the Tokyo Bay area and Tama River in Japan. The isolated bacteria belonged to the phyla Actinobacteria, Firmicutes, Proteobacteria and Bacteroidetes, indicating that the BaP-degrading bacteria were widely present in the hydrosphere. ITB11, which shared 100% 16S rRNA identity with Mesoflavibacter zeaxanthinifaciens in the phylum Bacteroidetes, showed the highest degradation of BaP (approximately 86%) among the nine isolated strains after 42 days. Moreover, it was found that three of the nine isolated strains collectively removed 50-55% of BaP during the first 7 days.

    Rubella is usually a mild illness, with febrile rash being its main symptom. However, serious consequences of rubella infection can result when the infection occurs during the early stages of pregnancy. After the occurrence of a rubella outbreak in Japan that was observed from 2012 to 2013, 45 infants were reportedly born with congenital rubella syndrome (CRS). We prospectively followed the 15 CRS cases reported in Tokyo to determine the virus shedding periods by using nested reverse transcriptase-polymerase chain reaction to detect rubella virus genes. Throast swabs were used for virus detection. The virus shedding period was measured from birth until the time when the sample last tested positive followed by 2 consecutive negative samples. Kaplan-Meier method was used to estimate the proportion of cases remaining positive for rubella virus genes over time. The proportion of CRS cases shedding virus dropped steadily after birth, dropping to 33.8% at 6 months and 16.9% at 12 months. Our findings also suggested that the earlier the mother's onset of rubella during pregnancy, the longer the infant remained positive. Based on our findings, we believe that infants with CRS should be monitored for rubella virus shedding until 1 year of age.

    Water temperature, salinity, nutrient concentrations and the composition of the plankton community were recorded at three stations in inner Tokyo Bay over a period of 328 days (from June 8, 1995 to April 30, 1996) with a nominal sampling frequency of once per day. Inspection of the results revealed that the data could be divided into two blocs as an aid to analysis: the period from June to October was characterized by the development of stratification of temperature and salinity (stratification period), and November to March was characterized by uniform temperature and salinity in the water column due to vertical mixing (mixing period). Oxygen-depleted water forms in the bottom layer during the stratification period, but vertical mixing of the water column, due to changing wind and rainfall conditions caused by passing weather fronts, results in the breakdown of the oxygen-depleted water mass. Nutrient loads are high in the surface water due to the freshwater supply, but occasional pulses of primary production cause a depletion of phosphate in the surface water, suggesting that the phosphorus becomes a limiting nutrient for phytoplankton growth in this period. Several short-term peaks of plankton abundance (blooms) occurred as responses to temporal changes in water quality from June to November, with consequent species succession. Significant fluctuations in the densities of the diatom Skeletonema costatum and several species of ciliates corresponded to the daily changes in the physical and chemical characteristics of the coastal environment. During the mixing period, when water temperature and solar radiation decreased, there were no short-term variations in water quality and although nutrient concentrations gradually increased from November to February, primary production remained low. This study shows that the short-term dynamics of the phytoplankton community are closely coupled to fluctuations in environmental forcing, and that the degree of coupling is

    Nuclear forensics is the analysis of intercepted illicit nuclear or radioactive material and any associated material to provide evidence for nuclear attribution by determining origin, history, transit routes and purpose involving such material. Nuclear forensics activities include sampling of the illicit material, analysis of the samples and evaluation of the attribution by comparing the analysed data with database or numerical simulation. Because the nuclear forensics methodologies provide hints of the origin of the nuclear materials used in illegal dealings or nuclear terrorism, it contributes to identify and indict offenders, hence to enhance deterrent effect against such terrorism. Worldwide network on nuclear forensics can lead to strengthening global nuclear security regime. In the ESARDA Symposium 2015, the results of research and development of fundamental nuclear forensics technologies performed in Japan Atomic Energy Agency during the term of 2011-2013 were reported, namely (1) technique to analyse isotopic composition of nuclear material, (2) technique to identify the impurities contained in the material, (3) technique to determine the age of the purified material by measuring the isotopic ratio of daughter thorium to parent uranium, (4) technique to make image data by observing particle shapes with electron microscope, and (5) prototype nuclear forensics library for comparison of the analysed data with database in order to evaluate its evidence such as origin and history. Japan’s capability on nuclear forensics and effective international cooperation are also mentioned for contribution to the international nuclear forensics community.

    Toxoplasma gondii is an important human health concern with respect to abortion, congenital hydrocephalus, and encephalitis in immunocompromised people. Cats and dogs both are potential sources of T. gondii because they have close contact with humans. However, no epidemiological surveys have been conducted in Tokyo over the past decade. Therefore, the present study investigated and compared the seroprevalence of T. gondii infection in shelter cats and dogs during 1999-2001 and 2009-2011 in Tokyo, Japan. Serum samples were collected from 337 shelter cats and 325 shelter dogs in urban and suburban areas of Tokyo, during 1999-2001 (233 cats and 219 dogs) and 2009-2011 (104 cats and 106 dogs). T. gondii antibodies were measured in the serum samples using a commercial latex agglutination test. Data were compared using the Fisher's exact test, and significance was indicated at P cats was 5.6% (13 of 233) in 1999-2001 and 6.7% (7 of 104) in 2009-2011, and that in dogs was 1.8% (4 of 219) and 1.9% (2 of 106), respectively. Significantly higher seroprevalence was observed in cats from suburban areas compared with cats in urban areas during both periods (P cats and dogs in Tokyo is considerably low as the seroprevalence has reached a steady state.

    Landslides represent a frequent and threatening natural disaster. The aim of this study was to investigate the injury patterns observed after a landslide and to discuss how to minimize the damage caused by a landslide disaster. A landslide occurred on Oshima Island, Japan, on October 16, 2013. A total of 49 victims with landslide-related injuries were identified and analyzed. The patients ranged in age from 5 to 89 years with an average age of 61.0±19.3 years. Of all patients, 69.4% were triaged as black. Of 15 patients who were treated in the nearest hospital (the only hospital on the island), 8 were triaged as red and yellow with severe chest or pelvic injury and a high Injury Severity Score (average score, 25.6; range, 4-45). Of these, 75% had chest injury and 75% had pelvic injury. The percentage of chest and/or pelvic injury was 100% in patients triaged as red or yellow. Traumatic asphyxia was diagnosed in 62.5% of these patients. Compression of the trunk was the main injury in patients triaged as red or yellow after this landslide disaster. Evacuation in advance, the rapid launch of emergency medical support, and knowledge of this specific injury pattern are essential to minimize the potential damage resulting from landslide disasters.

    Delay in seeking care is one of the critical issues in tuberculosis (TB) control among homeless persons in Japan. Yet knowledge of and attitude towards TB among homeless persons have remained unclear and limited efforts have been made to disseminate information related to TB among homeless persons. To evaluate the effect of TB leaflets, produced and distributed to homeless persons by a group of ex-homeless TB patients, and to understand what homeless persons know about TB. Self-administered questionnaire was conducted among homeless persons before and after distribution of the TB leaflets. Changes in the responses to each question were also subjected to principal component analysis to group questions into types according to response patterns and identify constructs of TB-related knowledge. Results of 88 participants were analyzed. TB knowledge score related to risks and symptoms significantly improved after the intervention (from 54.3% to 70.6%, p < 0.05), while knowledge on treatment cost did not. Two components were identified, namely, the "improvement in TB impression" and "improvement in TB knowledge". TB leaflets were effective in improving certain aspects of TB knowledge. However, its effect on knowledge regarding treatment cost, which may be crucial in improving delay, was limited and thus the messages need to be revised.

    Japan has not succeeded in reducing the annual number of new HIV-infected patients, although the prevalence of HIV infection is low (0.02%). A single-center observational study was conducted at the largest HIV clinic in Tokyo, which treats 15% of the total patients in Japan, to determine the reasons for having diagnostic tests in newly infected individuals. HIV-infected patients who visited our clinic for the first time between 2011 and 2014 were analyzed. The 598 study patients comprised one-third of the total reported number of new patients in Tokyo during the study period. 76% were Japanese MSM. The reasons for being tested which led to the diagnosis was voluntary testing in 32%, existing diseases in 53% (AIDS-defining diseases in 22%, sexually transmitted infections (STI) in 8%, diseases other than AIDS or STIs in 23%) and routine pre-surgery or on admission screening in 15%. 52% and 74% of the study patients and patients presented with AIDS, respectively, had never been tested. The median CD4 count in patients with history of previous testing (315/μL) was significantly higher than that of patients who had never been tested (203/μL, pTokyo metropolitan area.

    We investigated the prevalence of 5 enteric viruses (norovirus [NoV], sapovirus, rotavirus, astrovirus, and adenovirus) in archived stool specimens collected from 70 foodborne gastroenteritis outbreaks in Tokyo, Japan, which occurred from 1966 to 1983, and genetically characterized these viruses. NoV was detected in 48 (68.6%) outbreaks, while SaV, group C rotavirus (RVC), and astrovirus were detected in 1 (1.4%) outbreak each. Based on the partial capsid sequences, the detected NoVs were classified into the following genotypes: 9 in genogroup I (GI; GI.1-6, GI.8, GI.9, and GI.NA), 13 GII (GII.1-9, GII.13, GII.16, GII.17, and GII.22), and one in GIV. The oldest NoV outbreaks occurred in 1966. No predominant genotype was found. One strain, classified as GI. NA based on the N/S region sequence, was subsequently classified as GI.8 based on the complete VP1 sequence. Nine types of recombinant NoV sequences, including 7 unreported combinations, were identified. Further genetic characterization of NoV GII.17 and GII.4 demonstrated that the NoV GII.17 strains detected from 1970 to 1982 clustered independently from previously reported NoV GII.17 strains. Phylogenetic analysis, using the complete VP1 region and the P2 domain, demonstrated that NoV GII.4 strains collected between 1975 and 1980 clustered with archival strains collected in the USA in the mid-1970s. In contrast, a NoV GII.4 strain collected in 1983 formed an independent branch from reference strains collected in the mid-1970s to 2012.

    Few studies have evaluated the effect of short-term exposure to particulate matter (PM) less than 2.5μm in diameter (PM2.5) or to coarse particles on infant mortality. We evaluated the association between short-term exposure to PM and infant mortality in Japan and assessed whether adverse health effects were observable at PM concentrations below Japanese air quality guidelines. We used a time-stratified, case-crossover design. The participants included 2086 infants who died in the 23 urbanized wards of the Tokyo Metropolitan Government between January 2002 and December 2013. We obtained measures of PM2.5 and suspended particulate matter (SPM; PM<7μm in diameter) from one general monitoring station. As a measure of coarse particles, we calculated PM7-2.5 by subtracting PM2.5 from SPM. We then used conditional logistic regression to analyze the data. Same-day PM2.5 was associated with increased risks of infant and postneonatal mortality, especially for mortality related to respiratory causes. For a 10μg/m(3) increase in PM2.5, the odds ratios were 1.06 (95% confidence interval: 1.01-1.12) for infant mortality and 1.10 (1.02-1.19) for postneonatal mortality. PM7-2.5 was also associated with an increased risk of postneonatal mortality, independent of PM2.5. Even when PM2.5 and SPM concentrations were below Japanese air quality guidelines, we observed adverse health effects. This study provides further evidence that acute exposure to PM2.5 and coarse particles (PM7-2.5) is associated with an increased risk of infant mortality. Further, rigorous evaluation of air quality guidelines for daily average PM2.5 and larger particles is needed. Copyright © 2016 Elsevier B.V. All rights reserved.

    The public's perception of risk has a strong influence on a country's energy choices. As with civil aviation, bioengineering, or any other advanced technology, nuclear power does not come with absolute safety guarantees. What is important is that the risks and benefits are clearly understood. All members of the nuclear community - scientists, operators and safety regulators - should make every effort to provide accurate and easily understood information to improve public understanding of the risks and benefits of nuclear energy. Common misconceptions can be of great influence in shaping public acceptance of nuclear power. How a given nation balances the risk of a nuclear accident against other factors - such as air pollution, dammed rivers, mining accidents, or dependency on foreign fuel supplies - is already a matter of complexity and legitimate debate. It is essential that the nuclear community be seen as transparent and open in its activities, to increase understanding and confidence in the safe operations of nuclear facilities

    In Japan, infectious diseases are classified into 4 types based on how contagious and severe the pathogens are, and Ebola virus disease (EVD) is categorized as a category 1 infectious disease. The National Center for Global Health and Medicine in Tokyo, Japan, is designated as a specified hospital for category 1 infectious disease patients and has experienced 4 probable cases of EVD from West Africa. Even after the outbreak in West Africa is ended, we should continue to pay attention for new EVD outbreaks. Increasing the number of infectious disease specialists with the proper knowledge of viral hemorrhagic fever, including EVD, is a common problem for infectious disease physicians working in Japan, the academic society, and the government.

    Earthquakes sometimes cause serious disasters not only directly by ground motion itself but also secondarily by infrastructure damage, particularly in densely populated urban areas. To reduce these secondary disasters, it is important to rapidly evaluate seismic hazards by analyzing the seismic responses of individual structures due to the input ground motions. Such input motions are estimated utilizing an array of seismometers that are distributed more sparsely than the structures. We propose a methodology that integrates physics-based and data-driven approaches in order to obtain the seismic wavefield to be input into seismic response analysis. This study adopts the replica exchange Monte Carlo (REMC) method, which is one of the Markov chain Monte Carlo (MCMC) methods, for the estimation of the seismic wavefield together with one-dimensional local subsurface structure and source information. Numerical tests show that the REMC method is able to search the parameters related to the source and the local subsurface structure in broader parameter space than the Metropolis method, which is an ordinary MCMC method. The REMC method well reproduces the seismic wavefield consistent with the true one. In contrast, the ordinary kriging, which is a classical data-driven interpolation method for spatial data, is hardly able to reproduce the true wavefield even at low frequencies. This indicates that it is essential to take both physics-based and data-driven approaches into consideration for seismic wavefield imaging. Then the REMC method is applied to the actual waveforms observed by a dense seismic array MeSO-net (Metropolitan Seismic Observation network), in which 296 accelerometers are continuously in operation with several kilometer intervals in the Tokyo metropolitan area, Japan. The estimated wavefield within a frequency band of 0.10-0.20 Hz is absolutely consistent with the observed waveforms. Further investigation suggests that the seismic wavefield is successfully

    A total of 160 autochthonous dengue cases transmitted by Aedes albopictus were reported between August and October of 2014 in Tokyo Metropolis, Japan. Ae. albopictus is a medically important vector of dengue virus, which has expanded its geographic distribution in temperate regions. Understanding the distribution and biting density of Ae. albopictus during the 2014 dengue outbreak in Tokyo is important to evaluate the epidemic risks of dengue fever in other highly populated cities in Europe and Asia. Of the 160 patients, 134 visited the same park (Yoyogi Park) located in central Tokyo. Mosquitoes infected with dengue virus were collected from this park, suggesting that it was the exclusive location for the transmission of dengue. This study aimed to collect referential data to estimate the transmission threshold of dengue virus in terms of biting density of Ae. albopictus and determined high transmission risk areas of dengue virus in Yoyogi Park and its vicinity. The overall mean density of biting Ae. albopictus (7.13/man/8 min) was sufficiently high for successful transmission of dengue virus, and areas with biting densities higher than the overall mean density were classified as high risk areas for the transmission of dengue virus in Yoyogi Park.

    Full Text Available Toxoplasma gondii is an important human health concern with respect to abortion, congenital hydrocephalus, and encephalitis in immunocompromised people. Cats and dogs both are potential sources of T. gondii because they have close contact with humans. However, no epidemiological surveys have been conducted in Tokyo over the past decade. Therefore, the present study investigated and compared the seroprevalence of T. gondii infection in shelter cats and dogs during 1999-2001 and 2009-2011 in Tokyo, Japan.

T. gondii antibodies were measured in the serum samples using a commercial latex agglutination test. Data were compared using the Fisher's exact test, and significance was indicated at P < 0.05. The overall seroprevalence of T. gondii infection in cats was 5.6% (13 of 233 in 1999-2001 and 6.7% (7 of 104 in 2009-2011, and that in dogs was 1.8% (4 of 219 and 1.9% (2 of 106, respectively. Significantly higher seroprevalence was observed in cats from suburban areas compared with cats in urban areas during both periods (P < 0.05. These results reveal that there has been little change in the feline and canine seroprevalence over the past decade, indicating that the risk of T. gondii exposure for cats and dogs in Tokyo is considerably low as the seroprevalence has reached a steady state.

  7. The metropolis of Tokyo.

    The Tokyo metropolis houses 11,892,016 people, 1/10 of the Japanese population. In recent years, Tokyo's population growth has slowed as the birthrate has fallen from a 1947 postwar high of 31.5/1000 to 11.4/1000 in 1983. 5.9 million males and 5.8 million females, composing 4 1/2 million households, live in Tokyo's 2160 square kilometers. Within the metropolis' 23 wards, density per square kilometer was 14,023 persons in 1983, with Toshima ward containing 21,844 people per square kilometer. Wards around the city's center held 71% of the population in 1983, but had only 27% of its land mass; outlying cities, towns, and villages held 28% of the population on 54% of the land. 50% of Tokyo's population is aged 25-59; those 65 or over will rise from 1980's 9% to 15.6% of the population in 2000. In 40 years, Japan will have more elderly people than any other advanced country. In 1983, Tokyo had over 150,000 housing starts, high by Japanese and international standards. Nearly 1/4 of Tokyo households each contain a married couple with 2 children, but single person households predominate, reflecting Tokyo's student, working bachelor, and elderly populations. Young, single Japanese workers spend 1/3 of their income on leisure, entertainment, cultural activities and education; couples marry late and, with 2 incomes, can purchase many nonessentials. Nearly 3.25 million students attend Tokyo's fiercely competitive schools and colleges; Japan is almost 100% literate. Of the 6 million people working in Tokyo, half work in the service and retail sector, 25% in manufacturing, 12% in transportation and communication, 9% in finance and insurance, and 8% work in construction. Tokyo workers earn nearly 20% more than the average Japanese worker. Japan now faces job shortages and will see many unemployment problems by 1990. To help absorb new workers, government planners recommend increasing vacation time, training workers as specialists rather than generalists, and encouraging job

    We estimated inflow rates of perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA) to Tokyo Bay, Japan, between February 2004 and February 2011 by a receptor-oriented approach based on quarterly samplings of the bay water. Temporal trends in these inflow rates are an important basis for evaluating changes in PFOS and PFOA emissions in the Tokyo Bay catchment basin. A mixing model estimated the average concentrations of these compounds in the freshwater inflow to the bay, which were then multiplied by estimated freshwater inflow rates to obtain the inflow rates of these compounds. The receptor-oriented approach enabled us to comprehensively cover inflow to the bay, including inflow via direct discharge to the bay. On a logarithmic basis, the rate of inflow for PFOS decreased gradually, particularly after 2006, whereas that for PFOA exhibited a marked stepwise decrease from 2006 to 2007. The rate of inflow for PFOS decreased from 730kg/y during 2004-2006 to 160kg/y in 2010, whereas that for PFOA decreased from 2000kg/y during 2004-2006 to 290kg/y in 2010. These reductions probably reflected reductions in the use and emission of these compounds and their precursors in the Tokyo Bay catchment basin. Our estimated per-person inflow rates (i.e., inflow rates divided by the estimated population in the basin) for PFOS were generally comparable to previously reported per-person waterborne emission rates in Japan and other countries, whereas those for PFOA were generally higher than previously reported per-person waterborne emission rates. A comparison with previous estimates of household emission rates of these compounds suggested that our inflow estimates included a considerable contribution from point industrial sources.

    Sediment transport at river mouths, which consists of suspended-load and bed-load, has not been fully understood, since bed-load transport of cohesive sand is difficult to observe. Especially, the impact of sediment transport on the total amount of fine-grained cohesive sediment has not been elucidated. Cesium-134 and cesium-137 were spread from the Fukushima Daiichi Nuclear Power Plant (FDNPP) after the earthquake of March 11 of 2011, and attached to the fine-grained sand on the land. The contaminated sand flowed into the river mouths through the rivers possibly due to the complex physical processes in estuarine areas. To evaluate the fine-grained sediment transport around Tokyo and Tokyo Bay, field observations were carried out utilizing radionuclide originated from FDNPP as an effective tracer. The cohesive sediment transport at three different river mouths around Tokyo was successfully quantified. The cohesive sediment transport deposited in the estuary was found to be greatly dependent on the land use, geometry, river discharge and salinity. In addition,the transport driven by the rainfall was minute, and its behavior was quite different from suspended solids. Although further field observations of radionuclide are necessary, it is clear that fine-grained sediment in the bay from rivers already settled on the river mouth by aggregation. The settled sand will not move even in rainfall events. Consequently, the transport of radionuclide to the Pacific Ocean may not occur.; Cesium distribution around Tokyo Bay ; Cesium Concentration in Edogawa river

    The river sediment is basically composed of clastic materials derived from the surface of the Earth. Purpose of our study is clarify the quantitative estimation of ratio of influence given to river sediment of nature and human activity by using of heavy metals. We show the geochemical and geological characteristics of stream sediments from the Tama, Tsurumi, Edo and Ara Rivers that flow in Tokyo bay, Japan. We show research results of the degree of contamination in above four rivers that are the relativery polluted river in Japan. Sediment samples collected from various points along the upper and lower streams were subjected to content analysis and elution analysis (using liquate (flow) out test) on the heavy metals like Cd, CN, Pb, Cr(6+), As and Hg from the river sediment for the purpose of environment assessment. Content of Cd, CN, Pb, Cr(6+), As, and Hg except Pb was above the environmental quality limit in few locations of the Tsurumi river. However, in the down-river part (mouth region) Pb-concentration was 10 times higher than at the source regions as the result of human impact; for Hg the same tendency was detected at the all rivers. This study is the first research that investigated river sediment in the light of the envirnomental quality standard in Tokyo area, Japan.

  17. The Role of Sub-National Actors in Climate Change Policy. The Case of Tokyo

    Tokyo is known as a pioneer throughout the history of Japan's environmental policy, often being compared to California in the United States or Paris in France. Following the global trend of growing local initiatives tackling climate change, Tokyo introduced a cap-and-trade scheme in 2010 ahead of a national implementation. The Tokyo Cap-and-Trade Program is the first of its kind that regulates CO 2 emissions from all business sectors, where energy consumers are defined in terms of the business establishments they own. Tokyo's initiative is largely seen as a reaction to the modest national commitment, following the tradition of center-local rivalry. This study first explains the centre-local relationship in the history of Japan's environmental governance. It then analyzes the development of the Tokyo's flagship climate policy and its implications for national and other sub-national governments in Japan. The tactics used by the Tokyo Metropolitan Government to overcome business opposition typically seen in the introduction of GHG control, and future policy challenges are also discussed. The study finds that Tokyo's policy encourages behavioral changes and technological improvement in the business sector, going a step beyond the existing culture of energy conservation in Japan. An emission trading scheme is often associated with the collapse of carbon markets and the 'money game', rather than a practical tool to reduce CO 2 emissions, but the Tokyo Cap-and-Trade Program has demonstrated a policy impact that recasts such an image. A known case of policy diffusion to Saitama prefecture, an immediate neighbor of Tokyo with the fifth largest population in Japan, is also discussed to elaborate on the potential domestic diffusion of the policy.

    Previous research has produced conflicting findings concerning whether birthdays are associated with an increased risk of suicide. This study examined the association in Tokyo, Japan. Suicide data (ICD-10 codes X60-X84) for the period 2001-2010 were obtained from the Japanese Ministry of Health, Labour and Welfare. A time-stratified case-crossover design was used with conditional logistic regression analysis being performed to estimate within-subject 'birthday exposures' while controlling for meteorological conditions and public holidays. There were 27,007 suicides in the study period. For males the 5 days before the birthday and the week after the birthday were associated with significantly higher odds for suicide with the odds ratio being highest on the actual birthday (OR =1.677, 95% CI: 1.294, 2.172). For females, significantly higher odds for completed suicide were observed 7-11 days before the birthday. Stratified analyses showed different at risk time patterns among men from different age groups, and that married men had higher odds for suicide on, and for the 4 days before and in the 2 weeks after their birthday. We lacked detailed information on suicides which would have enabled a better understanding of the observed associations. Birthdays are associated with an increased risk for suicide in Tokyo, Japan. Health professionals who work with individuals at risk of suicide should be made aware that birthdays are associated with an elevated suicide risk. This information should also be communicated in wider suicide prevention campaigns. Copyright © 2016 Elsevier B.V. All rights reserved.

  19. Effect of water temperature on survival of early-life stages of marbled flounder Pseudopleuronectes yokohamae in Tokyo Bay, Japan.

    We investigated factors that might have disturbed the stock recovery of marbled flounder in Tokyo Bay by focusing on the early life stages. Field surveys in Tokyo Bay from 2006 to 2011 revealed that mature adult biomass increased from 2006 to 2008 and decreased thereafter. Meanwhile, larval and juvenile densities were high in 2006 and 2008 but low in other years. Discrepancies in the yearly trends of these parameters suggest that mortality during life stages between spawning and early larval phases might have affected the abundance of the subsequent life stages. Monthly mean water temperature between January and February, in which hatching and pelagic larvae occur in the bay, was lower in 2006 (8.6 °C) and 2008 (9.6 °C) than was observed in other years (10.4-11.4 °C). Significant negative correlation between water temperature and larval density implies that mortality during pre- and post-larval stages would be higher in warmer winter years (>10 °C). To test this hypothesis, we examined the effects of water temperature on mortality and development in egg and larval stages under controlled laboratory conditions. Hatching rate was high in a water temperature range of 9.2-12.7 °C (66.6-82.5%), whereas it decreased in cooler (3.7% at 5.9 °C) or warmer (33.9% at 14.8 °C) conditions. Meanwhile, days from fertilization to hatching, size of larvae at hatching and survival rate of larvae after 18 d from hatching were monotonically and significantly decreased as water temperature was elevated. Combined evidence of the field and laboratory studies suggests that a warmer reproductive season (>10 °C) might induce mortalities of marbled flounder larvae in Tokyo Bay.

    The 11 March 2011 M 9.0 Tohoku earthquake generated significant long duration shaking that propagated hundreds of kilometers from the epicenter and affected urban areas throughout much of Honshu. Recorded responses of tall buildings at several hundred km from the epicenter of the main shock and other events show tall buildings were affected by long-period motions of events at distant sources. This study presents behavioral aspects of 29-story and 30-story neighboring buildings in the Shinjuku area of Tokyo, Japan, as inferred from records retrieved from a sparse array of accelerometers deployed in the superstructures, at ground and 100 m below the ground level over a time interval covering before, during, and after the main shock. Such long-period effects are common in several regions of Japan as well as in the United States and in other seismically active countries. Permanent shifts in fundamental frequencies are observed. Drift ratios indicate possible structural nonlinear behavior occurred during the main shock. The need to consider risks to built environments from distant sources, including those in neighboring countries, is emphasized.

    This study examined the factors affecting a women's initial intimate partner violence (IPV)-specific health care seeking event which refers to the first health care seeking as a result of IPV in a lifetime. Data were collected using the Life History Calendar method in the Tokyo metropolitan area from 101 women who had experienced IPV. Discrete-time survival analysis was used to assess the time to initial IPV-specific health care seeking. IPV-related injury was the most significant factor associated with increased likelihood of seeking IPV-specific health care seeking for the first time. In the presence of a strong effect of formal help seeking, physical and sexual IPV were no longer significantly related to initial IPV-specific health care seeking. The results suggest some victims of IPV may not seek health care unless they get injured. The timing of receiving health care would be important to ensure the health and safety of victims. © The Author(s) 2014.

    In order to clarify the impact of air pollution on the formation of sudden and locally distributed heavy rain in urban areas (hereafter UHR = urban-induced heavy rain), we analyzed inorganic ions in rainwater samples collected on an event basis over 5 years from October 2012 to December 2016 in Shinjuku, Tokyo. Hourly rainfall amounts and wet deposition fluxes of acidic components (the sum of H+, NH4+, NO3-, and nonsea-salt SO42-) in UHR were 13.1 and 17.8 times larger than those in normal rainfall, respectively, indicating that large amount of air pollutants were scavenged and deposited by UHR with large amounts of rainfall. The level of air pollutants, such as NO2, SO2, and potential ozone, in the ambient air increased just before the formation of UHR and decreased sharply at the end of the UHR event. These results indicate that NO2, which was formed secondarily by oxidants, was further oxidized by HO radicals and formed HNO3 just before the formation of UHR, which was subsequently scavenged by UHR.

    '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)

    Aims: To investigate the chronic effects of air pollution caused mainly by automobiles in healthy adult females. Methods: Respiratory symptoms were investigated in 5682 adult females who had lived in the Tokyo metropolitan area for three years or more in 1987; 733 of them were subjected to pulmonary function tests over eight years from 1987 to 1994. The subjects were divided into three groups by the level of air pollution they were exposed to during the study period. The concentrations of nitrogen dioxide and suspended particulate matter were the highest in group 1, and the lowest in group 3. Results: The prevalence rates of respiratory symptoms in group 1 were higher than those in groups 2 and 3, except for wheezing. Multiple logistic regression analysis showed significant differences in persistent phlegm and breathlessness. The subjects selected for the analysis of pulmonary function were 94, 210, and 102 females in groups 1, 2, and 3, respectively. The annual mean change of FEV1 in group 1 was the largest (-0.020 l/y), followed by that in group 2 (-0.015 l/y), and that in group 3 (-0.009 l/y). Testing for trends showed a significant larger decrease of FEV1 with the increase in the level of air pollution. Conclusions: The subjects living in areas with high levels of air pollution showed higher prevalence rates of respiratory symptoms and a larger decrease of FEV1 compared with those living in areas with low levels of air pollution. Since the traffic density is larger in areas with high air pollution, the differences among the groups may reflect the effect of air pollution attributable to particulate matter found in automobile exhaust.

    To describe the trajectory of, and examine factors affecting, intimate partner violence (IPV) and IPV-specific healthcare seeking among Japanese women over the life course. Life course study. One hundred and one women, aged 24-80 years, who had a lifetime history of IPV were interviewed in the Tokyo metropolitan area, Japan in 2005 and 2006. Life course data were collected according to the life history calendar method. Hierarchical linear modelling was used to examine IPV-specific healthcare seeking over the life course. Injury, formal or informal help seeking, public assistance, worse self-rated health status and smoking significantly increased the likelihood of IPV-specific healthcare seeking over the life course. There are significant cohort effects on healthcare seeking. The results suggest that women who experience IPV may seek healthcare services not only immediately after the first occurrence of IPV, but also later in life. IPV is not always associated with immediate healthcare seeking. In particular, sexual IPV is not significantly associated with healthcare seeking. Pursuing formal and informal help is associated with healthcare seeking. Copyright © 2013 The Royal Society for Public Health. Published by Elsevier Ltd. All rights reserved.

    Synchrotron radiation research in Japan started in early 1960's when the first electron synchrotron was commissioned at the Institute of Nuclear Study (INS), University of Tokyo (UT). This review covers the parasite use of the INS electron synchrotron and research works done at the light sources in Japan such as SOR-RING, Photon Factory (KEK-PF) Accumulator Ring (KEK-AR), and SPring-8. History of synchrotron radiation research in Japan was overviewed by paying attention to the creative works in the development of light sources and related technology, as well as the pioneering works on the development of experimental techniques and methods. At present there are more than ten synchrotron radiation sources are in operation and the number of their users, especially users from industries in Japan is increasing very rapidly and the research fields of users are also developing. Accordingly the synchrotron radiation facility becomes more and more indispensable facility in the society in Japan. (author)

    2009-10-01

    We conducted laboratory experiments to verify molecular techniques of avian malaria parasite detection distinguishing between an infected mosquito (oocysts on midgut wall) and infective mosquito (sporozoites in salivary glands) in parallel with blood-meal identification from individual blood-fed mosquitoes prior to application to field survey for avian malaria. Domestic fowl infected with Plasmodium gallinaceum was exposed to a vector and non-vector mosquito species, Aedes aegypti and Culex pipiens pallens, respectively, to compare the time course of polymerase chain reaction (PCR) detection for parasite between competent and refractory mosquitoes. DNA of the domestic fowl was detectable for at least 3 days after blood feeding. The PCR-based detection of P. gallinaceum from the abdomen and thorax of A. aegypti corresponded to the microscopic observation of oocysts and sporozoites. Therefore, this PCR-based method was considered useful as one of the criteria to assess developmental stages of Plasmodium spp. in mosquito species collected in the field. We applied the same PCR-based method to 21 blood-fed C. sasai mosquitoes collected in Rinshi-no-mori Park in urban Tokyo, Japan. Of 15 blood meals of C. sasai successfully identified, 86.7% were avian-derived, 13.3% were bovine-derived. Plasmodium DNA was amplified from the abdomen of three C. sasai specimens having an avian blood meal from the Great Tit (Parus major), Pale Thrush (Turdus pallidus), and Jungle Crow (Corvus macrorhynchos). This is the first field study on host-feeding habits of C. sasai in relation to the potential role as a vector for avian malaria parasites transmitted in the Japanese wild bird community.

  14. Congener-specific metabolism and sequestration of dioxin-like compounds by cytochrome P450 1A induced in the liver of crows from Tokyo, Japan

    Jungle crow (JC; Corvus macrorhynchos) is a useful bioindicator for monitoring contaminants in urban areas, because this species is residential, occupies a same habitat as human, and feeds variety of foods including domestic waste and garbage. Therefore, JCs may accumulate environmental contaminants such as polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs) and coplanar polychlorinated biphenyls (Co-PCBs), which are released by human activities. Induction of cytochrome P450 (CYP) 1A is a responsive mechanism elicited by exposure to dioxinlike compounds including PCDDs/DFs and Co-PCBs. Toxicokinetic behavior of dioxin-like compounds in organisms is controlled by excretion, metabolism and absorption. These processes are, at least partly, dependent on CYP1A expression in addition to chemical structure and number of chlorine substitution of each congener. Low chlorinated congeners such as 2378-T{sub 4}CDD, 2378- T{sub 4}CDF, 12378-P{sub 5}CDD and 33'44'-PCB were easily metabolized by CYP1A1/2 in rat liver microsomes. PCDDs/DFs accumulate in hepatic tissue to a greater extent than adipose tissue in rats and mice. Recent study using transgenic CYP1A2 knockout mice demonstrated that CYP1A2 is responsible for the sequestration of 2378-T{sub 4}CDD and 23478-P{sub 5}CDF in hepatic tissue. Therefore, CYP1A is considered as a key factor responsible for toxicokinetics of dioxin-like compounds. However, there's no comprehensive data on the contribution of CYP1A to the toxicokinetics of dioxin-like congeners in wild populations. In this study, we investigated contamination levels of PCDDs/DFs and Co-PCBs in liver and breast muscle of JCs from Tokyo, Japan, and interactions of dioxin-like congeners with hepatic CYP to elucidate congener-specific toxicokinetics related to CYP expression in JC.

    Empirical data indicative of the health conditions and medical needs of homeless persons are scarce in Japan. In this study, with the aim of contributing to the formulation of future healthcare strategies for the homeless, we conducted a self-administered questionnaire survey and interviews at a park in Shinjuku Ward, Tokyo, to clarify the living conditions of homeless persons and their health conditions and awareness about the availability of medical treatment. Responses from 55 homeless men were recorded (response rate: 36.7%). With the exception of one person, none of them possessed a health insurance certificate. Half of the respondents reported having a current income source, although their modal monthly income was 30,000 yen($1 was approximately 90 yen). The number of individuals who responded "yes" to the questions regarding "Consulting a doctor on the basis of someone's recommendation" and "Being aware of the location of the nearest hospital or clinic" was significantly higher among those who had someone to consult when they were ill than among those who did not (the odds ratios [95% confidence intervals] were 15.00 [3.05-93.57] and 11.45 [1.42-510.68], respectively). This showed that whether or not a homeless person had a person to consult might influence his healthcare-seeking behavior. When queried about the entity they consulted (multiple responses acceptable), respondents mentioned "life support organizations" (61.1%) and "public offices" (33.3%). Overall, 94.5% of the respondents were aware of swine flu (novel influenza A (H1N1)). Their main sources of information were newspapers and magazines. On the basis of these findings, with regard to the aim of formulating healthcare strategies for homeless persons, while life support organizations and public offices play significant roles as conduits to medical institutions, print media should be considered useful for communicating messages to homeless persons.

    2010-01-01

    Recently, the number of human immunodeficiency virus (HIV)-positive patients has increased in Japan. HIV-positive patients are at a higher risk of cancer than the general population. This paper retrospectively reports the acute adverse effects of radiation therapy on HIV-positive patients who were treated at Tokyo Metropolitan Cancer and Infectious diseases Center Komagome Hospital (TMCICK). Thirty-one cases involving 24 HIV-positive cancer patients who were treated at TMCICK from January 1997 to March 2009 were included in this study. All acute adverse effects of radiation therapy were examined during, and one month after, the last radiation therapy session. Acute adverse effects were classified according to the site of radiation therapy treatment and analyzed using the Common Terminology Criteria for Adverse Events (CTCAE) version 3.0. Grade 3 acute adverse effects were seen in 17% of cases, and Grade 2 toxicities were found in 23% of patients. Damage to the skin and mucosa, including stomatitis or diarrhea, tended to occur after low-dose radiation therapy; however, no severe acute adverse effects were seen in other organs, such as the brain, lung, and bone. Acute adverse effects tended to occur earlier in HIV-positive patients and became severe more frequently than in the general population. In particular, disorders of the mucosa, such as those of the oral cavity, pharynx, and intestine, tended to occur rapidly. It was shown that radiation therapy is safe when treatment is performed carefully and that it is a very useful treatment for cancer in HIV-positive patients. (author)

    Three years have passed since the publication of the Tokyo Guidelines for the management of acute cholangitis and cholecystitis, and we believe that the time has come to assess their validity. In this study, we validated the diagnostic accuracy of these criteria in 74 patients with an initial diagnosis of acute cholangitis and 81 patients with an initial diagnosis of acute cholecystitis. We also statistically compared the accuracy of the diagnosis made based on the Tokyo Guidelines with that based on the presence of Charcot's triad for acute cholangitis and Murphy's sign for acute cholecystitis with use of the sign test to assess differences. The results revealed that the diagnostic sensitivity and specificity of the Tokyo Guidelines for suspected or definitive acute cholangitis were 72.1 and 38.5%, respectively, and the corresponding values for definitive cholangitis alone were 63.9 and 69.2%, respectively. For definitive acute cholecystitis, the diagnostic sensitivity and specificity of the Tokyo Guidelines were 84.9 and 50.0%, respectively. The accuracy of diagnosis based on the Tokyo Guidelines was significantly higher than that based on the presence of Charcot's triad (acute cholangitis, p Tokyo Guidelines should be used more widely for the diagnosis of acute cholangitis and cholecystitis in the twenty-first century. Hereafter, various efforts should be made to improve the sensitivity and specificity of the diagnostic criterion of the Tokyo Guidelines.

  18. History of healthcare technology assessment in Japan.

    There has been a rapid growth of healthcare technology assessment (HTA) activities among health service researchers and physicians in Japan in the younger generation since the mid-1980s. HTA has become visible since the Ministry of Health, Labor, and Welfare (MHLW) set up the several committees related to HTA in the late 1990s. The MHLW had to participate in regulatory and administrative reform, coping with the serious economic stagnation since 1991, following the economic recession in the 1980s. However, HTA has not been developed as expected. The most important failure is that the application of HTA to health policy has been neglected by the MHLW. Only application to clinical practice has been implemented by developing evidence-based clinical practice guidelines. The MHLW had the main aim of containing costs by reducing excess or useless healthcare services through guidelines, rather than to implement a radical reform. Without a central organization for HTA, several researchers have still continued to do HTA studies, but most researchers and physicians promoting HTA have been moved into diverse related areas. Ultimately, increasing efficiency may be the only way of reconciling rising demands for health care with public financing constraints. Therefore, the reconsideration and reorganization of HTA, which covers not only healthcare services but also the healthcare system as a whole, is becoming an urgent matter for healthcare reform.

    The objective of this study was to determine the resource utilization of a tertiary care Japanese emergency department (ED) that was not immediately adjacent to the area of the 2011 Great East Japan earthquake and tsunami. A retrospective chart review was performed at a tertiary care university-based urban ED located approximately 290 km from the primary site of destruction secondary to an earthquake measuring 9.0 on the Richter Scale and the resulting tsunami. All patients who presented for a period of twelve days before and twelve days after the disaster were included. Data were collected using preformed data collection sheets, and stored in an Excel file. Abstracted data included gender, time in the ED, intravenous fluid administration, blood transfusion, oxygen, laboratories, electrocardiograms (ECGs), radiographs, ultrasound, diagnoses, surgical and medical referrals, and prescriptions written. Ten percent of the charts were reviewed for accuracy, and an error rate reported. Data were analyzed using 2-tailed t-tests, Fisher's exact tests or rank sum tests. Bonferroni correction was used to adjust P values for multiple comparisons. Charts for 1193 patients were evaluated. The error rate for the abstracted data was 3.2% (95% CI, 2.4%-4.1%). Six hundred fifty-seven patients (53% male) were evaluated in the ED after the earthquake, representing a 23% increase in patient volume. Mean patient time spent in the ED decreased from 61 minutes to 52 minutes (median decrease from 35 minutes to 32 minutes; P = .005). Laboratory utilization decreased from 51% to 43% (P = .006). The percentage of patients receiving prescriptions increased from 48% to 54% (P = .002). There was no change in the number of patients evaluated for surgical complaints, but there was an increase in the number treated for medical or psychiatric complaints. There was a significant increase in the number of people utilizing the ED in Tokyo after the Great East Japan earthquake and tsunami. Time spent

    Objectives Previous studies of Japanese migrants have suggested that the increase in colorectal cancer rates occurring after migration is slower among Japanese Brazilians than Japanese Americans. We hypothesized that this difference may partly reflect differences in vegetable and fruit intake between populations. Methods Using data from validation studies of food frequency questionnaires being used in a comparative case-control study of colorectal adenoma in Tokyo, São Paulo, and Hawaii, plasma carotenoids, retinol, tocopherols, and coenzyme Q10 levels were measured by high-performance liquid chromatography, and 25-hydroxy vitamin D levels by enzyme-linked immunosorbent assay. Plasma levels were compared by analysis of covariance between 142 Japanese in Tokyo, 79 Japanese Brazilians in São Paulo, and 78 Japanese Americans in Hawaii. Results Overall, we found significantly lower plasma carotenoid levels, except for lycopene, and retinol levels in Japanese Americans than in Japanese in Tokyo and Japanese Brazilians. Plasma total carotenoids level was highest in Japanese Brazilians. Compared to mean level among Japanese Brazilians (1741.2 ng/mL), p for difference was 0.03 for Japanese in Tokyo (1514.4 ng/mL) and Tokyo than in Japanese Americans and Japanese Brazilians. Conclusion Higher levels of plasma carotenoids among Japanese Brazilians than Japanese in Tokyo and Hawaii may contribute to the slower pace of increase in colorectal cancer rates observed in that population following migration.

    The main building of the Institute of Technical Investigation of Ohbayashi Corporation in Tokyo, Japan, was built with the objective of being the best all over the world in the grounds of energy conservation. The utilization of this building was initiated on April 15, 1982 registering an annual energy consumption in the first two years of 87 and 96 Million calories/m{sup 2} respectively, that is, less than one fourth the consumption in conventional buildings. The inside ambient is better or equal to the one of ordinary buildings and the time for the investment recuperation was estimated of 8.7 years. The classification for the energy consumption in those first two years was of 31% for air conditioning, 41% for lighting/wall receptacles and 25% for others. The maximum consumption was in the month of August and was of 10 to 11 Mcal/m{sup 2}. The minimum consumption corresponded to the month of November and was 6 to 7 Mcal/m{sup 2}. In 1984 this building won the prize Energy of the ASHRAE. A total od 98 conservation measures were adopted for its construction and operation.

Plasma lycopene and tocopherol levels did not substantially differ between the three populations. We also found significantly lower plasma levels of 25-hydroxy vitamin D and total coenzyme Q10 in Japanese in Tokyo than in Japanese Americans and Japanese Brazilians. Higher levels of plasma carotenoids among Japanese Brazilians than among Japanese in Tokyo and Hawaii may have contributed to the slower pace of the increase in colorectal cancer rates observed in that population after migration.

    In central Japan, the Philippine Sea plate (PSP) subducts beneath the Tokyo Metropolitan area, the Kanto region, where it causes mega-thrust earthquakes, such as the 1703 Genroku earthquake (M8.0) and the 1923 Kanto earthquake (M7.9) which had 105,000 fatalities. A M7 or greater earthquake in this region at present has high potential to produce devastating loss of life and property with even greater global economic repercussions. The Central Disaster Management Council of Japan estimates the next great earthquake will cause 11,000 fatalities and 112 trillion yen (1 trillion US$) economic loss. This great earthquake is evaluated to occur with a probability of 70 % in 30 years by the Earthquake Research Committee of Japan. We had started the Special Project for Earthquake Disaster Mitigation in Tokyo Metropolitan area (2007-2012). Under this project, the construction of the Metropolitan Seismic Observation network (MeSO-net) that consists of about 400 observation sites was started [Kasahara et al., 2008; Nakagawa et al., 2008]. Now, we had 178 observation sites. The correlation of the wave is high because the observation point is deployed at about 2 km intervals, and the identification of the later phase is recognized easily thought artificial noise is very large. We also discuss the relation between a deformation of PSP and intra-plate M7+ earthquakes: the PSP is subducting beneath the Honshu arc and also colliding with the Pacific plate. The subduction and collision both contribute active seismicity in the Kanto region. We are going to present a high resolution tomographic image to show low velocity zone which suggests a possible internal failure of the plate; a source region of the M7+ intra-plate earthquake. Our study will contribute a new assessment of the seismic hazard at the Metropolitan area in Japan.

    Full Text Available Geological disaster by liquefaction-fluidization happened on southern part of the Quaternary Paleo-Kanto submarine basin at the 2011 Earthquake off the Pacific Coast of Tohoku. Liquefaction-fluidization phenomena occurred mainly in man-made strata over shaking 5+ intensity of Japan Meteorological Agency scale. Many subsided spots, 10–50 m width, 20–100 m length and less than 1 m depth, by liquefaction-fluidization distributed on reclaimed land around northern Tokyo bay. Large amount of sand and groundwater spouted out in the terrible subsided parts. But there are little subsidence and no jetted sand outside the terrible subsided part. Liquefaction-fluidization damaged part at the 1987 earthquake east off Chiba prefecture re-liquefied and fluidized in these parts at the 2011 great earthquake. The damaged area were more wide on the 2011 earthquake than the 1987 quake. Detailed classification maps of subsidence by liquefaction-fluidization on the 2011 grate earthquake were made by fieldwork in Chiba city around Tokyo bay. A mechanism of subsidence by liquefaction-fluidization in man-made strata was solved by geological survey with continuous large box cores on the ACE Liner and large relief peals of the cores at a typical subsided part.

    The 11 March 2011 M 9.0 Tohoku earthquake generated long-duration shaking that propagated hundreds of kilometers from the epicenter and affected tall buildings in urban areas several hundred kilometers from the epicenter of the main shock. Recorded responses show that tall buildings were affected by long-period motions. This study presents the behavior and performance of a 37-story building in the Tsukuda area of Tokyo, Japan, as inferred from modal analyses of records retrieved for a time interval covering a few days before, during, and for several months after the main shock. The U.S. “code-type” array comprises three triaxial accelerometers deployed at three levels in the superstructure. Such a sparse array in a tall structure limits a reliable assessment, because its performance must be based on only the average drift ratios. Based on the inferred values of this parameter, the subject building was not structurally damaged.

    By applying instrumental neutron activation analysis techniques, a survey was carried out to determine the levels of a variety of trace element concentrations in human hair of the inhabitants of the Tokyo metropolitan area. A total of 202 scalp hair samples were collected from the inhabitants of the residential district in the western part of the Tokyo metropolitan area. The donors were divided into five age groups, ranging from pre-school age to sixty years and above. Each group consisted of twenty males and twenty or more females. The sampling method and washing procedure recommended by the IAEA Advisory Group on the applications of nuclear methods in environmental research were strictly followed. Irradiation of the samples was made in the Rikkyo University 100-kW TRIGA MARK II reactor. By using several combinations of irradiation time, cooling time and counting time, the following 37 elements were quantitatively analysed: Ag, Al, As, Au, Ba, Br, Ca, Cd, Ce, Cl, Co, Cr, Cu, Fe, Hg, I, K, La, Mg, Mn, Mo, Na, Ni, Rb, S, Sb, Sc, Se, Sm, Sn, Te, Ti, U, V, W and Zn. NBS standard reference orchard leaves and bovine liver were also analysed in the course of the hair analysis to assess the precision of the analytical techniques. (author)

    Application of the new techniques and improvements in air cleaning systems have been made to reduce release of radioactive materials from nuclear facilities based on the ALARA concept. For example, the reduction of release of radioactive gaseous effluents has been made by installation of a charcoal gas hold-up system and a clean steam supply system for a turbine gland seal in a BWR and of a gas decay tank system in a PWR. In connection with the effort for reduction of releases in plants, research and development on air cleaning technology have also been made. Some activities mentioned in the present paper are: removal of particulates, airborne radioiodine, noble gases and tritium; penetration characteristics of submicron DOP aerosol for HEPA filters; radioiodine removal from air exhausts; and operational performance of the incineration plants using ceramic filters

    Health Technology Assessment (HTA) is the systematic evaluation to measure the value of new health technologies. It improves the quality of choices on hand for cost-effective health technologies that are considered valuable. Japan has built a society of longevity consisted of the institution of the universal health care system, which is financially unsustainable. In Japan, no independent HTA organization has been publicly established but the government is contemplating implementation of such system. To advance the usage of HTA into surgery, we need to establish methods for evaluating new surgical technologies with steep learning curves. The promotion of clinical researches is also essential, especially by taking advantage of observational studies from medical big data such as the Japanese nationwide database which has more than four million surgical cases registered. In addition, we need more clinical information regarding each surgical patient's quality of life and socioeconomic status. The countries already introduced HTA into their health care system have measures to solve the problems that arose and have developed necessary evaluating methods. To introduce and promote HTA in Japan without taking away the benefit of our current healthcare, it is required that surgeons collaborate with other specialists such as methodologists and health economists.

    The objective of this study was to investigate the effects of long-time commuting and long-hour working on lifestyle including sleeping, physical exercise, breakfast, smoking, alcohol intake and mental health. In this cross-sectional study, data were collected from 146 school teachers in Tokyo. The binary associations of commuting time and working hours with lifestyle, mental stress measured by the General Health Questionnaire (GHQ) and stress coping measured by the Sense of Coherence (SOC) scores were examined. The Chi-square test was used for statistical analyses. Our results indicated that the mean commuting time and working hours per week of the respondents were 42.1 (SD 22.5) minutes and 50.4 (SD 8.6) hours, respectively. Longer commuting time was significantly associated with shorter working hours (p = 0.023), less physical exercise (p health questionnaire; sense of coherence

    1995-07-01

    This August marks 50 years since the end of World War II. Japan emerged from the ruins to overcome the post-war devastation to achieve a high level of economic growth and become the second largest economy in the world. Science and technology have played major roles as a driving force behind this quest for prosperity. However, it seems as though true prosperity is not necessarily being enjoyed by citizens of Japan today. Japan is becoming an aging society. To realize a truly rich and prosperous society in which people can live comfortably, it is important to further raise the level of science and technology. It is also necessary to ensure this development by revitalizing the economy, and to continue to utilize science and technology as an endless resource to create assets for society as a whole which will be inherited by future generations. With this viewpoint in mind, this White Paper looks back on Japan's scientific and technological development over the last 50 years, and considers the future of science and technology with a view toward realizing the true prosperity for its people. It is our hope that this White Paper will be helpful for considering the scientific and technological activities needed to bring about a Japan whose people are truly prosperous, and we will, as a government, continually increase our efforts toward the promotion of science and technology.

    Full Text Available The training vessel Umitaka-maru of the Tokyo University of Marine Science and Technology (TUMSAT undertook a marine science cruise in the Indian sector of the Southern Ocean during the 2011/2012 austral summer. During the cruise, TUMSAT conducted five different collaborative research projects. These included two phase-VIII Japanese Antarctic Research Expedition (JARE-52 to -57 projects: "Responses of Antarctic Marine Ecosystems to Global Environmental Changes with Carbonate Systems", which is the sub-theme of the prioritized research project "Exploring Global Warming from Antarctica"; and the ordinary research project "Studies on Plankton Community Structure and Environment Parameters in the Southern Ocean". The other three collaborative research projects were those undertaken in conjunction with (1 the National Institute of Polar Research, entitled "Environment and Ecosystem Changes in the Southern Ocean"; (2 the Japan Agency for Marine-Earth Science and Technology (JAMSTEC, entitled "Deployment of the Southern Ocean Buoy" ; and (3 with Hokkaido University, entitled "Studies on Dynamics of Antarctic Bottom Water". The Umitaka-maru departed from Fremantle, Australia, on 27 December 2011, sailed to the study area around the marginal sea ice zone (mainly along 110°E and 140°E, and returned to Hobart, Australia, on 1 February 2012. The participants performed various net castings to qualitatively evaluate the vertical distribution of plankton communities, made physical observations, and measured chemical parameters. They also retrieved a year-round mooring that had been deployed the previous year, retrieved two surface drifting buoys that had been released by the ice breaker Shirase, and deployed a JAMSTEC buoy (m-TRITON. In addition, several acidified culture experiments using pteropods were conducted on board.

    In this paper I review the present condition of the regeneration medicine research using pluripotency and a somatic stem cell, and I describe the subject of the science and technology policy in Japan towards realization of regeneration medicine. The Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT) supported research promotion by the prompt action in 2007 when establishment of the iPS cell was reported by Shinya Yamanaka. Although the hospitable support of the Japanese government to an iPS cell is continued still now, there are some problems in respect of the support to other stem cell researches, and industrialization of regeneration medicine. In order to win a place in highly competitive area of investigation, MEXT needs to change policy so that funds may be widely supplied also to stem cell researches other than iPS cell research.

    Japan consists of 3900 islands and lies off the east coast of Asia. Even though Japan is one of the most densely populated nations in the world, its growth rate has stabilized at .5%. 94% of all children go to senior high school and almost 90% finish. Responsibility for the sick, aged, and infirmed is changing from the family and private sector to government. Japan was founded in 600 BC and its 1st capital was in Nara (710-1867). The Portuguese, the 1st Westerners to make contact with Japan in 1542, opened trade which lasted until the mid 17th century. US Navy Commodore Matthew Perry forced Japan to reopen in 1854. Following wars with China and Russia in the late 1800s and early 1900s respectively, Japan took part in World Wars I and II. In between these wars Japan invaded Manchuria and China. The US dropped an atomic bomb on Hiroshima and Nagasaki and the Japanese surrendered in September, 1945 ending World War II (WWII). Following, WWII, the Allied Powers guided Japan's establishment as a nonthreatening nation and a democratic parliamentary government (a constitutional monarchy) with a limited defense force. Japan remains one of the most politically stable of all postwar democracies. The Liberal Democratic Party's Noboru Takeshita became prime minister in 1987. Japan has limited natural resources and only 19% of the land is arable. Japanese ingenuity and skill combine to produce one of the highest per hectare crop yields in the world. Japan is a major economic power, and its and the US economies are becoming more interdependent. Its exports, making up only 13% of the gross national product, mainly go to Canada and the US. Many in the US are concerned, however, with the trade deficit with Japan and are seeking ways to make trade more equitable. Japan wishes to maintain good relations with its Asian neighbors and other nations. The US and Japan enjoy a strong, productive relationship.

    We investigated active screening for colonization with methicillin-resistant Staphylococcus aureus (MRSA) on admission and weekly follow-up surveillance after admission to a tertiary care center (TCC) between June 2007 and 31 December 2007. Eleven percent (30/267) of patients were found to be positive for MRSA by polymerase chain reaction (PCR) and/or culture on admission; 5% (12/267) became positive during the TCC stay. The major primary diagnoses in MRSA-positive patients were pneumonia and cerebrovascular diseases. Twenty-two (52%) of 42 patients were found to be MRSA positive by both PCR and culture, compared with 19 (45%) of 42 who were PCR positive and culture negative. These findings suggest that active surveillance with PCR is highly sensitive and useful for the detection of MRSA colonization. To our knowledge, this is the first report of active surveillance of MRSA by PCR and bacterial culture in critically ill inpatients in Japan.

    The current intense discussion of the green house effect, that has been one of the main focuses on the carbon cycle in environmental systems of the earth, seems to be weakened the importance related to the effect of carbonic materials on substance movement in the aquatic environments; though it has just begun to be referred recently. Because dissolved organic carbon (DOC) in stream flows believes to play a main role of the carbon cycle in the fresh water environment, seasonal changes in DOC discharge were investigated in catchments with various scale and land use, especially in forested catchments which are one of the important sources of DOC. In order to understand the fundamental characteristics of the discharge of dissolved organic materials, stream flows, DOC, and fulvic acid like materials (FA) included in stream flows were measured in a coniferous forested head watershed. The watershed is located at the southeast edge of the Kanto mountain and is 40 km west of Tokyo with the elevation from 720 to 820 m and mean slope gradient of 38 degrees. Geology of the watershed is underlain by the sequence of mud and sand stones in Jurassic and the soil in the watershed is Cambisol (Inceptisols). The watershed composes of a dense cypress and cedar forest of 45 years old with poor understory vegetation. Observations were carried out for 6 rain storms of which the total precipitations ranged between 16.2 and 117.4 mm. The magnitude of the storms was classified into small, middle, and big events on the basis of the total precipitation of around 20, 40, and more than 70 mm. Stream flows were collected during the storm events by 1 hour interval and were passed through the 0.45 μm filters, and then the DOC concentrations in the flows were measured with a total organic carbon analyzer. The relative concentrations of fulvic acid (FA) in the flows were monitored with three dimensional excitations emission matrix fluorescence spectroscopy, because fulvic acid shows distinctive

    In 2020, Japan will host the Tokyo Olympic and Paralympic Games in 2020 (Tokyo 2020) which will involve a large population influx from various countries to Tokyo, the most populated city in Japan. We summarize the potential health risks for visitors to Tokyo 2020, related to communicable disease risks and other health threats, based on recent national and local surveillance reports. We reviewed up-to-date surveillance reports published by the National Institute of Infectious Diseases and Tokyo Metropolitan Infectious Disease Surveillance Center. Communicable disease risks for vaccine-preventable illnesses such as measles and rubella, as well as food and waterborne diseases represent the most likely risks. The risk of acquiring vector-borne diseases is considered low in Japan. On the other hand, however, heat-related illness represents a potential risk, as Tokyo 2020 is scheduled during the hottest season in Japan, with temperatures generally expected to exceed 30 °C. Maintaining an up-to-date routine vaccination schedule is highly recommended for visitors attending the Tokyo 2020 and appropriate hygiene measures for food and waterborne diseases as well as health promotion for heat-related illness. It may also be useful to increase the number of multilingual triage clinicians whom can be placed within emergency departments during the Tokyo 2020 to provide first contact services and coordination of emergency care among non-Japanese speaking visitors to Tokyo.

    The paper described the positioning and new development of clean coal technology. Coal is an important resource which supplies approximately 30% of the energy consumed in all the world. In the Asian/Pacific region, especially, a share of coal in energy is high, around 60% of the world, and it is indispensable to continue using coal which is abundantly reserved. Japan continues using coal as an important energy among petroleum substituting energies taking consideration of the global environment, and is making efforts for development and promotion of clean coal technology aiming at further reduction of environmental loads. Moreover, in the Asian region where petroleum depends greatly upon outside the region, it is extremely important for stabilization of Japan`s energy supply that coal producing countries in the region promote development/utilization of their coal resources. For this, it is a requirement for Japan to further a coal policy having an outlook of securing stable coal supply/demand in the Asian region. 6 figs., 2 tabs.

    The Tokyo Axion Helioscope experiment aims to detect axions which are produced in the solar core. The helioscope uses a strong magnetic field in order to convert axions into X-ray photons and has a mounting to follow the sun very accurately. The photons are detected by an X-ray detector which is made of 16 PIN-photodiodes. In addition, a gas container and a gas regulation system are adopted for recovering the coherence between axions and photons in the conversion region giving sensitivity to axions with masses up to 2 eV. In this paper, we report on the technical detail of the Tokyo Axion Helioscope.

    Introduction TOMACS research project has been started since 2010 July in order to develop the elementary technologies which are required for the adaptation of societies to future global warming impacts that cannot be avoided by the reduction of greenhouse gases. In collaboration with related government institutions, local governments, private companies, and residents, more than 25 organizations and over 100 people are participated. TOMACS consists of the following three research themes: Theme 1: Studies on extreme weather with dense meteorological observations Theme 2: Development of the extreme weather early detection and prediction system Theme 3: Social experiments on extreme weather resilient cities Theme 1 aims to understand the initiation, development, and dissipation processes of convective precipitation in order to clarify the mechanism of localized heavy rainfall which are potential causes of flooding and landslides. Theme 2 aims to establish the monitoring and prediction system of extreme phenomena which can process real-time data from dense meteorological observation networks, advanced X-band radar network systems and predict localized heavy rainfalls and strong winds. Through social experiments, theme 3 aims to establish a method to use information obtained by the monitoring system of extreme phenomena to disaster prevention operations in order to prevent disasters and reduce damage. Social Experiments Toyo University is the core university for the social experiments accomplishment. And following organizations are participating in this research theme: NIED, the Tokyo Metropolitan Research Institute for Environmental Protection (TMRIEP), University of Tokyo, Tokyo Fire Department (TFD), Edogawa Ward in Tokyo, Yokohama City, Fujisawa City and Minamiashigara City in Kanagawa, East Japan Railway Company, Central Japan Railway Company, Obayashi Corporation, and Certified and Accredited Meteorologists of Japan(CAMJ).

    The 25-item Work Limitations Questionnaire (WLQ-25) measures presenteeism but has not been sufficiently validated in a Japanese population. A total of 451 employees from four information technology companies in Tokyo completed the WLQ-25 and questionnaires of other variables on two occasions, 2 weeks apart. The WLQ-25 yielded a two-factor structure: Cognitive Demand and Physical Demand. These subscales showed good internal consistency, and both were associated with adverse working conditions, greater perceived job strain, lower skill use, poorer workplace social support, and less satisfactory psychological adjustment. Intraclass correlation coefficients of the two WLQ-25 subscales between time 1 and time 2 were 0.78 and 0.55, respectively. This study suggests acceptable psychometric properties of the WLQ-25 in Japan.

    Upon request from the Government of Japan an IAEA expert mission was conducted at the Kashiwazaki-Kariwa NPP following a strong earthquake that affected the plant on 16 July 2007. Thus, the mission complemented the ongoing safety evaluations of the incident as they are currently being performed by Japan's Nuclear and Industrial Safety Agency, Japan's Nuclear Safety Commission and the plant operator, the Tokyo Electric Power Company. The scope of the mission was limited to three subject areas: Area 1: Seismic design basis - design basis ground motions Preliminary investigations of the actual earthquake and its ground motions and comparison with the design basis ground motions for the plant seismic design. Area 2: Plant behaviour - structures, systems and components Observation of the damage that occurred as a consequence of the earthquake of 16 July 2007 to the seven units at Kashiwazaki-Kariwa nuclear power plant site on the basis of the information gathered and made available by TEPCO and by performing limited but representative plant walkdowns. Area 3: Operational safety management Preliminary investigations of the operational safety management response and releases of radioactive material during and after the earthquake, on the basis of the examination of documents and of discussions with TEPCO. The mission report is composed of two volumes, Volume I and Volume II. This Volume II contains all supporting documentation and information collected during the mission and provided by the counterpart to the IAEA Expert Team. It is arranged in a way that it will be relatively easy for the reader to find the necessary information. There is a significant amount of information contained in Volume II that has come from different sources and that has been gathered for different purposes.

  5. Getting Lost in Tokyo

    2014-07-01

    Full Text Available This paper explores the potential for using alternative forms of inscriptive practice to describe the urban space of the Tokyo Subway. I begin with an account of the process of getting lost in Shinjuku Subway Station in the heart of Tokyo. This station represents a limit condition of place, being dense and complex beyond the powers of traditional architectural representation. The station is explored through serial translations, beginning with narrative, moving to a flowchart diagram, Laban dance notation, recurring motifs and archetypes, architectural drawing, photography, and cartography. As Claudia Brodsky Lacour and Tim Ingold describe, the form our inscriptive practices take are crucial to the ways in which we conceptualise those places. How much of the experience of a place is lost in the traditional inscriptive practices of the architect? This description of the urban space of the Tokyo subway forms the basis for an extended study exploring the description of this experience of place, and the power of such description to theorise space. The ultimate aim of this is to shift the focus of urban design away from geometric principles and towards the experiences that might be enjoyed in such places.

    Japan frequently suffers from all types of disasters such as earthquakes, typhoons, floods, volcanic eruptions, and landslides. In the first half of this year, we already had three big earthquakes and heavy rainfall, which killed more than 30 people. This is not just for Japan but Asia is the most disaster-afflicted region in the world, accounting for about 90% of all those affected by disasters, and more than 50% of the total fatalities and economic losses. One of the most essential ways to reduce the damage of natural disasters is to educate the general public to let them understand what is going on during those desasters. This leads individual to make the sound decision on what to do to prevent or reduce the damage. The Ministry of Education, Culture, Sports, Science and Technology (MEXT), therefore, offered for public subscription to choose several model areas to adopt scientific education to the local elementary schools, and ERI, the Earthquake Research Institute, is qualified to develop education for earthquake disaster prevention in the Tokyo metropolitan area. The tectonic setting of this area is very complicated; there are the Pacific and Philippine Sea plates subducting beneath the North America and the Eurasia plates. The subduction of the Philippine Sea plate causes mega-thrust earthquakes such as the 1703 Genroku earthquake (M 8.0) and the 1923 Kanto earthquake (M 7.9) which had 105,000 fatalities. A magnitude 7 or greater earthquake beneath this area is recently evaluated to occur with a probability of 70 % in 30 years. This is of immediate concern for the devastating loss of life and property because the Tokyo urban region now has a population of 42 million and is the center of approximately 40 % of the nation's activities, which may cause great global economic repercussion. To better understand earthquakes in this region, "Special Project for Earthquake Disaster Mitigation in Tokyo Metropolitan Area" has been conducted mainly by ERI. It is a 4-year

    UNFPA Executive Director, Dr. Nafis Sadik, visited Tokyo in February to publicize the organization and its activities. UNFPA worked in 1989 with a US $200 million budget on 3266 projects in 147 countries. Dr Sadik is currently UN Under Secretary General and gave a speech at the College Women's Association on the deterioration of the world environment. Environmental problems stem from industrialization and urbanization. World population will rise to 6.2 billion by 2000 (80% of which are in developing countries) and 8.5 billion by 2025. Developing countries are also becoming dumping grounds for developed countries' waste. Dr. Sadik stresses that women need to change their current status from childbearers to productive members of their societies who ca choose when to have a family and how large it will be. The next decade will be crucial for changes of attitude among governments and the role of non-governmental organizations. Dr. Sadik discussed the importance of Population Forum 21 where 24 Japanese policy makers met to discuss global population problems. She urged Japan to invest more finances, advice, and technical help in this major crisis. She also states that there are no boundaries for environmental and population problems, so we must all work on a solution together. Dr. Sadik praised the efforts of NGO's in this struggle.

    The number of elderly people in Japan is growing, which raises the issue of dementia, as the probability of becoming cognitively impaired increases with age. There is an increasing need for caregivers, who are well-trained, experienced and can pay special attention to the needs of people with dementia. Technology can play an important role in helping such people and their caregivers. A lack of mutual understanding between caregivers and researchers regarding the appropriate uses of assistive technologies is another problem. A vision of person-centred care based on the use of information and communication technology to maintain residents' autonomy and continuity in their lives is presented. Based on this vision, a roadmap and a list of challenges to realizing assistive technologies have been developed. The roadmap facilitates mutual understanding between caregivers and researchers, resulting in appropriate technologies to enhance the quality of life of people with dementia. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

  14. The impact of western science and technology on 'ukiyo-e' prints and book illustrations in late eighteenth and nineteenth century Japan.

    In the Edo period (c. 1600-1868), exposure to Western art, science and technology encouraged Japanese 'ukiyo-e' (pictures of the floating world) artists to experiment with Western perspective in woodblock prints and book illustrations. We can see its early influence in the work of Utagawa Hiroshige (1787-1858), as well as Utagawa Kuniyoshi (1797-1861). Unlike Hiroshige, Kuniyoshi lived to see the opening of the port of Yokohama to trade with the West in 1859. A whole genre of Yokohama prints emerged and one of the key artists was Utagawa Sadahide (1807-1873). In his illustrated books entitled 'Yokohama kaikō kenbunshi' (A Record of Things Seen and Heard in the Open Port of Yokohama) (1862), Sadahide plays with perspective in an effort to represent the dynamic changes that Japan was undergoing in its encounter with the West at the time. In the work of later artists such as Hiroshige III (1843-1894), Kobayashi Kiyochika (1847-1915) and Inoue Yasuji (1864-1889), we can see growing efforts to depict light, shadow and depth, and a continuing fascination with the steam locomotive and the changes occurring in the Tokyo-Yokohama region as Japan entered the Meiji period (1868-1912).

    Recombinant DNA technology was developed in the United States in the early 1970s. Leading scientists held an international Asilomar Conference in 1975 to examine the self regulation of recombinant DNA technology, followed by the U.S. National Institutes of Health drafting the Recombinant DNA Research Guidelines in 1976. The result of this conference significantly affected many nations, including Japan. However, there have been few historical studies on the self-regulation of recombinant technologies conducted by scientists and government officials in Japan. The purpose of this paper is to analyze how the Science Council of Japan, the Ministry of Education, Science adn Culture, and the Science and Technology Agency developed self-regulation policies for recombinant DNA technology in Japan in the 1970s. Groups of molecular biologist and geneticists played a key role in establishing guidelines in cooperation with government officials. Our findings suggest that self-regulation policies on recombinant DNA technology have influenced safety management for the life sciences and establishment of institutions for review in Japan.

  16. Preliminary findings and lessons learned from the 16 July 2007 earthquake at Kashiwazaki-Kariwa NPP- 'The Niigataken Chuetsu-Oki earthquake, Kashiwazaki-Kariwa NPP and Tokyo, Japan, 6-10 August 2007. Mission report. V. 1

    2007-01-01

    Upon request from the Government of Japan an IAEA expert mission was conducted at the Kashiwazaki-Kariwa NPP following a strong earthquake that affected the plant on 16 July 2007. The objective, as agreed with the Japanese counterpart, was to conduct a fact finding mission and to identify the preliminary lessons learned that might have implications for the international nuclear safety regime. Although the Niigataken Chuetsu-Oki earthquake on 16 July 2007 significantly exceeded the level of the seismic input taken into account in the design of the plant, the installation behaved in a safe manner, during and after the earthquake. In particular, the automatic shutdown of the reactors of Units 3, 4 and 7, which were operating at full power, and of the reactor of Unit 2, which was in the start up state, were performed successfully. Based on the reports from experts from the Tokyo Electric Power Company (TEPCO) and the limited but representative plant walkdowns and visual observations performed by the IAEA team, safety related structures, systems and components of the plant seem to be in a much better general condition than might be expected for such a strong earthquake, and there is no visible significant damage. This is probably due to the conservatisms introduced at different stages of the design process. The combined effects of these conservatisms were apparently sufficient to compensate for uncertainties in the data and methods available at the time of the design of the plant, which led to the underestimation of the original seismic input. However, important components like the reactor vessels, the core internals and the fuel elements have not yet been examined and in-depth inspections are still to be performed. On the other hand, non-safety related structures, systems and components were affected by significant damage such as soil and anchorage failures and oil leakages. A re-evaluation of the seismic safety the Kashiwazika-Kariwa NPP needs to be done with account

    Japan, known as a pro-choice country in terms of abortion, is currently facing the increase of “selective abortions” thanks to new prenatal screening. Efforts to restrict proliferation of new technology has not been successful and it is likely that Japan will turn pro-life by strictly enforcing the Maternity Protection Act (MPA), which prohibits abortions due to “fetal cause”.

    Tokyo and its outlying cities are home to one-quarter of Japan's 127 million people. Highly destructive earthquakes struck the capital in 1703, 1855 and 1923, the last of which took 105 000 lives. Fuelled by greater Tokyo's rich seismological record, but challenged by its magnificent complexity, our joint Japanese-US group carried out a new study of the capital's earthquake hazards. We used the prehistoric record of great earthquakes preserved by uplifted marine terraces and tsunami deposits (17 M???8 shocks in the past 7000 years), a newly digitized dataset of historical shaking (10 000 observations in the past 400 years), the dense modern seismic network (300 000 earthquakes in the past 30 years), and Japan's GeoNet array (150 GPS vectors in the past 10 years) to reinterpret the tectonic structure, identify active faults and their slip rates and estimate their earthquake frequency. We propose that a dislodged fragment of the Pacific plate is jammed between the Pacific, Philippine Sea and Eurasian plates beneath the Kanto plain on which Tokyo sits. We suggest that the Kanto fragment controls much of Tokyo's seismic behaviour for large earthquakes, including the damaging 1855 M???7.3 Ansei-Edo shock. On the basis of the frequency of earthquakes beneath greater Tokyo, events with magnitude and location similar to the M??? 7.3 Ansei-Edo event have a ca 20% likelihood in an average 30 year period. In contrast, our renewal (time-dependent) probability for the great M??? 7.9 plate boundary shocks such as struck in 1923 and 1703 is 0.5% for the next 30 years, with a time-averaged 30 year probability of ca 10%. The resulting net likelihood for severe shaking (ca 0.9g peak ground acceleration (PGA)) in Tokyo, Kawasaki and Yokohama for the next 30 years is ca 30%. The long historical record in Kanto also affords a rare opportunity to calculate the probability of shaking in an alternative manner exclusively from intensity observations. This approach permits robust estimates

    1996-01-01

    Fusion power reactor studies in Japan based on magnetic confinement schemes are reviewed. As D-T fusion reactors, a steady-state tokamak reactor (SSTR) was proposed and extensively studied at the Japan Atomic Energy Research Institute (JAERI) and an inductively operated day-long tokamak reactor (IDLT) was proposed by a group at the University of Tokyo. The concept of a drastically easy maintenance (DREAM) tokamak reactor is being developed at JAERI. A high-field tokamak reactor with force-balanced coils as a volumetric neutron source is being studied by our group at Tokyo Institute of Technology. The conceptual design of a force-free helical reactor (FFHR) is under way at the National Institute for Fusion Science. A design study of a D- 3 He field-reversed configuration (FRC) fusion reactor called ARTEMIS was conducted by the FRC fusion working group of research committee of lunar base an lunar resources.

    Healthcare reform as part of the economic recovery plan in Japan is placing emphasis on the use of healthcare information technology (HIT). This research mainly focuses on the HIT efforts in Japan with reference to the US for context. The purpose is to: (a) provide detail on governmental policy impacting promotion of HIT adoption to provide services to the people of Japan, (b) describe the outcomes of past and present policy impacting progress based on a case study of HIT use in the Kyoto Yamashina area, and (c) discuss issues for refinement of current policy. The method is case study, and data collection techniques include: (a) interviews of people involved in policy making for HIT in Japan (Japanese healthcare professionals, government officials, and academics involved in HIT research in Japan) and use in the medical community of HIT in the Kyoto Yamashina area, (b) archived document analysis of reports regarding government policy for HIT policy and user assessment for HIT mainly in the case study site, and (c) the literature review about HIT progression and effectiveness assessments to explore and describe issues concerning the transformation with HIT in Japan. This study reveals the aspects of governmental policy that have been effective in promoting successful HIT initiatives as well as some that have been detriments in Japan to help solve pressing social issues regarding healthcare delivery. For example, Japan has stipulated some standardized protocols and formats for HIT but does not mandate exactly how to engage in inter-organizational or intra-organizational health information exchange. This provides some desired autonomy for healthcare organizations and or governments in medical communities and allows for more advanced organizations to leverage current resources while providing a basis for lesser equipped organizations to use in planning the initiative. The insights gained from the Kyoto Yamashina area initiative reflect the success of past governmental

  3. Contesting the natural in Japan: moral dilemmas and technologies of dying.

    1995-03-01

    The paper opens with a discussion about the recognition of "whole-brain death" as the end of life in North America in order to perform solid organ transplants. This situation is contrasted with Japan, where, despite no financial or technological restrictions, brain death is not recognized, and transplants from brain-dead bodies cannot be performed. The Japanese cultural debate over the past twenty-five years about the "brain-death problem" is presented, followed by an analysis of Japanese attitudes towards technological intervention into what is taken to be the "natural" domain, together with a discussion of current Japanese attitudes towards death. This debate is interpreted as one aspect of a search for moral order in contemporary Japan, revealing ambivalence about self and other, Japan and the West, and tradition and modernity.

    The Second US - Japan Workshop on Global Change: Environmental Response Technologies for Global Change was hosted by the Program on Resources at the East-West Center, in Honolulu, Hawaii on February 1--3, 1993, on behalf of the United States Committee on Earth and Environmental Sciences (CEES) of the Federal Coordinating Council for Science, Engineering, and Technology (FCCSET). This workshop brought together over fifty leading scientists from the two countries to review existing technologies and to identify needed research on the development of new technologies for mitigation and adaptation of global change. The Workshop was organized around three areas of research: (1) capture, fixation/utilization, and disposal of CO{sub 2} (e.g. CO{sub 2}, separation and capture technologies, ocean and land disposal of CO{sub 2}; (2) energy production and conservation technologies to reduce greenhouse gas emissions (e.g. combustion efficiency, non-carbon based energy technologies, energy conservation technologies); and (3) adaptation technologies and practices related to global climate change (e.g., adaptation responses of crops to climate change, adapting urban infrastructure for climate change). Priorities for joint research in each of these areas were discussed. Selected papers have been processed separately for inclusion in the Energy Science and Technology Database.

    2013-01-01

    Following World War II, Japan miraculously developed into an economic powerhouse and a model of energy efficiency among developed countries. This lasted more than 65 years until the Northeastern Japan earthquake and tsunami induced nuclear crisis of March 2011 brought Japan to an existential crossroads. Instead of implementing its plans to increase nuclear power generation capacity from thirty percent to fifty percent, Japan shut-down all fifty-four nuclear reactors for safety checks and stress-checks (two have since been restarted), resulting in reduced power generation during the summer of 2012. The reconstruction of Northeastern Japan approaches at a time when the world is grappling with a transition to sustainable energy technologies—one that will require substantial investment but one that would result in fundamental changes in infrastructure and energy efficiency. Certain reconstruction methods can be inappropriate in the social, cultural and climatic context of disaster affected areas. Thus, how can practitioners employ sustainable reconstructions which better respond to local housing needs and availability of natural energy resources without a framework in place? This paper aims at sensitizing policy-makers and stakeholders involved in post disaster reconstruction by recognizing advantages of deploying sustainable energy technologies, to reduce dependence of vulnerable communities on external markets. - Highlights: • We examine the energy challenges faced by Japan in the aftermath of Fukushima. • We identify policy measures for the use of energy technologies applicable to disaster prone nations. • We evaluate the potential for renewable energy to support reduced reliance on nuclear energy in Japan. • We model scenarios for eco-towns and smart-cities in post-disaster reconstruction. • We assess the role of culture in formulating energy policy in post-disaster reconstruction

    It is difficult to carry out meta-analyses or to compare the results of different studies of biliary stents because there is no uniform evaluation method. Therefore, a standardized reporting system is required. We propose a new standardized system for reporting on biliary stents, the 'TOKYO criteria 2014', based on a consensus among Japanese pancreatobiliary endoscopists. Instead of stent occlusion, we use recurrent biliary obstruction, which includes occlusion and migration. The time to recurrent biliary obstruction was estimated using Kaplan-Meier analysis with the log-rank test. We can evaluate both plastic and self-expandable metallic stents (uncovered and covered). We also propose specification of the cause of recurrent biliary obstruction, identification of complications other than recurrent biliary obstruction, indication of severity, measures of technical and clinical success, and a standard for clinical care. Most importantly, the TOKYO criteria 2014 allow comparison of biliary stent quality across studies. Because blocked stents can be drained not only using transpapillary techniques but also by an endoscopic ultrasonography-guided transmural procedure, we should devise an evaluation method that includes transmural stenting in the near future. © 2014 The Authors.

    Safe disposal of high level radioactive waste (HLRW) has become a hot issue around the world and the people are generally concerned about it. The countries that have their own nuclear facilities regard safe disposal of HLRW as a strategic task, which can ensure sustainable industrial development and protect human health and natural environment. At present, deep geological disposal technology for HLRW is only executed and generally accepted in the world. China chose a geological disposal as the main direction for HLRW in 1985, the goal is to set up a national geological repository during 2030-2040. There are still a range of issues and challenges for safe disposal of HLRW in science, technology and engineering because the complexity of the geological disposal system and long-term potential hazards of HLRW. The United States, Finland and Japan have carried out a great deal of research and practice on geological disposal, it is worth to learn from them. This paper introduces Japan geological disposal plan, organization and implementation, fields and topics of research and development on the geological disposal in order to know experience and technology of Japan in the geological disposal, continuously improve our HLRW geologic disposal programs and technology.

    Medicare pioneered add-on payments to facilitate the adoption of innovative technologies under its hospital prospective payment system. US policy makers are now experimenting with broader value-based payment initiatives, but these have not been adjusted for innovation. This article examines the structure, processes, and experience with Medicare's hospital new technology add-on payment program since its inception in 2001 and compares it with analogous payment systems in Germany, France, and Japan. Between 2001 and 2015 CMS approved nineteen of fifty-three applications for the new technology add-on payment program. We found that the program resulted in $201.7 million in Medicare payments in fiscal years 2002-13-less than half the level anticipated by Congress and only 34 percent of the amount projected by CMS. The US program approved considerably fewer innovative technologies, compared to analogous technology payment mechanisms in Germany, France and Japan. We conclude that it is important to adjust payments for new medical innovations within prospective and value-based payment systems explicitly as well as implicitly. The most straightforward method to use in adjusting value-based payments is for the insurer to retrospectively adjust spending targets to account for the cost of new technologies. If CMS made such retrospective adjustments, it would not financially penalize hospitals for adopting beneficial innovations. Project HOPE—The People-to-People Health Foundation, Inc.

    Japanese companies were the first in the world to achieve a colorimetric glucose measurement meter back in 1973. Over the following 40 or so years, they succeeded in achieving a much greater level of user-friendliness and performance and in so doing, have contributed to the spread of self-monitoring of blood glucose. This article aims to unravel the history of blood glucose measurement's technological developments; to look at the direction and features of the development path Japan is taking; as well as to introduce some Japanese products that are on the market. © 2011 Diabetes Technology Society.

    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

    To date, there is no physical activity (PA) questionnaire with convergent and construct validity for the oldest-old. The aim of the current study was to investigate the validity of questionnaire-assessed PA in comparison with objective measures determined by uniaxial and triaxial accelerometers and physical performance measures in the oldest-old. Participants were 155 elderly (mean age 90 years) who were examined at the university and agreed to wear an accelerometer for 7 days in the 3-year-follow-up survey of the Tokyo Oldest-Old Survey of Total Health. Fifty-nine participants wore a uniaxial and triaxial accelerometer simultaneously. Self-rated walking, exercise, and household PA were measured using a modified Zutphen PA Questionnaire (PAQ). Several physical performance tests were done, and the associations among PAQ, accelerometer-assessed PA, and physical performances were compared by Spearman's correlation coefficients. Significant, low to moderate correlations between PA measures were seen on questionnaire and accelerometer assessments (ρ = 0.19 to 0.34). Questionnaireassessed PA measure were correlated with a range of lower extremity performance (ρ = 0.21 to 0.29). This PAQ demonstrated convergent and construct validity. Our findings suggest that the PAQ can reasonably be used in this oldest-old population to rank their PA level.

    A car-borne survey was made in metropolitan Tokyo, Japan, in December 2014 to estimate external dose. This survey was conducted for all municipalities of Tokyo and the results were compared with measurements done in 2003. The ambient dose rate measured in the whole area of Tokyo in December 2014 was 60 nGy h(-1) (23-142 nGy h(-1)), which was 24% higher than the rate in 2003. Higher dose rates (>70 nGy h(-1)) were observed on the eastern and western ends of Tokyo; furthermore, the contribution ratio from artificial radionuclides ((134)Cs and (137)Cs) to ambient dose rate in eastern Tokyo was twice as high as that of western Tokyo. Based on the measured ambient dose rate, the effective dose rate after the accident was estimated to be 0.45 μSv h(-1) in Tokyo. This value was 22% higher than the value before the accident as of December 2014. Copyright © 2016 Elsevier Ltd. All rights reserved.

    International Nuclear Information System (INIS)

    2013-01-01

    Following the accident at TEPCO's Fukushima Daiichi Nuclear Power Station (NPS) on 11 March 2011, the ''Mid-and-Long-Term Roadmap towards the Decommissioning of TEPCO's Fukushima Daiichi Nuclear Power Station Units 1-4'' was adopted by the Government of Japan and TEPCO Council on Mid-to-Long-Term Response for Decommissioning in December 2011 and revised in July 2012. The Roadmap, which is scheduled for an additional update in June 2013, describes the main steps and activities to be implemented for the decommissioning of the Fukushima Daiichi NPS through the combined efforts of the Government of Japan and TEPCO. Within the framework of the IAEA Action Plan on Nuclear Safety, the Government of Japan invited the IAEA to conduct an independent peer review of the Roadmap with two main objectives: - To improve the decommissioning planning and the implementation of pre-decommissioning activities at TEPCO's Fukushima Daiichi NPS; and - To share with the international community the good practices and lessons learned by the review. The review has been organized in two steps, and the IAEA conducted the first part in Japan from 15 to 22 April 2013. The objective of the first mission was to undertake an initial review of the Roadmap, including assessments of decommissioning strategy, planning and timing of decommissioning phases and a review of several specific short-term issues and recent challenges. Specifically, it covered the assessment of current reactor conditions, assessment of management of radioactive releases and associated doses, control of radioactive exposure of employees and decontamination within the site for improvement of working environment, structural integrity of reactor buildings and other constructions. The incidents recently experienced at the site, related with failures of the power supply and leakages of water from the underground reservoirs, were also included in the review of the specific short-term issues. The Government of Japan and TEPCO have

    International Nuclear Information System (INIS)

    2014-01-01

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

    Tokyo and its outlying cities are home to one-quarter of Japan's 127 million people. Highly destructive earthquakes struck the capital in 1703, 1855 and 1923, the last of which took 105,000 lives. Unlike California's seismic environment of shallow and largely strike-slip faults, Tokyo lies 200 km from a triple junction with two subduction zones, and 80 km from a front of active volcanoes. Further, some of the region's megathust faults are seismically coupled, some undergo episodic slip events, and others appear to be permanently aseismic. To reinterpret the tectonic structure, identify active faults and their slip rates, and estimate their earthquake frequency, we analyzed the 7,000-yr record of seventeen M~8 shocks preserved by uplifted marine terraces and tsunami deposits, and 150 GPS vectors in the past 10 years from Japan's GeoNet array. We also digitized 10,000 observations of historical shaking recorded over the past 400 years, and examined 300,000 earthquakes registered by the dense NIED/JMA network in a 3D geographic information system. In a principal departure from previous work, we propose that a 100-km-wide, 25-km-thick dislodged fragment of the Pacific plate is jammed between the Pacific, Philippine Sea and Eurasian plates beneath Tokyo, and argue that the this fragment controls much of Tokyo's seismic behavior, including the damaging 1855 M~7.1 Ansei-Edo shock. On the basis of the frequency of earthquakes beneath greater Tokyo, we estimate that events with magnitude and location similar to the Ansei-Edo event have a 20% likelihood in an average 30-yr period. In contrast, our renewal (time-dependent) probability for great M~7.9 megathrust shocks such as struck in 1923 and 1703 is just 0.5% for the next 30 years, with a time-averaged 30-yr probability of ~10%. The resulting net likelihood for severe shaking (~0.9 g peak ground acceleration) in Tokyo, Kawasaki, and Yokohama for the next 30 years is ~30%, and the annual probability is 1.3%.

    Research into applied aspects of biological hydrogen production is carried out on a much lower level in Europe than basic hydrogenase research. However, the screening for good H{sub 2} producers, their cultivation, and the development of optimised culture and bioreactor systems has never been a strength in Europe. Although there are a few good groups in Europe major contributions in this field traditionally come from countries outside Europe. However, in the nineties a special application-oriented research subfield has begun to evolve in Europe: the use of genetic enginering to rationally optimise H{sub 2} producing organisms. The most important players who focus on green algae, cyanobacteria, and purple bacteria can be found in Germany, France, and Sweden. In European biohydrogen research, a large and diverse variety of organisms is investigated. Among the organisms most thoroughly studied are Alcaligenes eutrophus, Escherichia coli, Rhodobacter capsulatus, sulfate-reducing bacteria, and methanogenic bacteria. Moreover, a leading position has been obtained with respect to molecular genetics of green algae and cyanobacteria, albeit on a low level. The fact that such a broad range of diverse organisms is studied has advantages and disadvantages. A positive aspect is that the multitude of different approaches had led to several unexpected results which had otherwise been overlooked. On the other hand, an obvious link to biohydrogen production is often lacking. Moreover, there are many 'me-too' approaches and results in which previous findings are only reproduced for another organism as well. (orig.)

    Contemporary Japan is known both for its high tech culture and its rapidly aging population, with 22 % of people currently 65 years and older. Yet there has been little attention to the material culture of the elderly. This paper explores the way aging bodies, official ideology, and consumption of what are called "assistive devices" and "life technologies" come together in the experience of frail old people who depend not only on human caregivers but on "things" such as walkers, kidney dialysis machines, and electric massage chairs. It begins to consider the questions: What technology to aid failing bodies is available, and to whom? How does the advocacy of independence create new forms of consumption? How do "things" mediate ideological change regarding elder care and help to create new understandings of self and one's relation to others? Data come from interviews conducted in 2003-2007 as part of a study of elder care in Japan under the public long term care insurance system that began in 2000. These interviews point both to acceptance of the technology as a way to avoid over-dependence on caregivers, and to resistance to the limitations of aging and to its 21st century definition by the state.

    As context may impact everyday technology (ET) use it is relevant to study this within different contexts. To examine the usefulness of the Everyday Technology Use Questionnaire (ETUQ) in different contexts by investigating and comparing (1) the level of challenge of ETs in the ETUQ and (2) the relevance of and perceived ability to use ET in samples of Swedish and Japanese older adults. The Swedish and the Japanese samples (n = 86/86) were interviewed using the ETUQ about relevance of and perceived ability to use ET. Data were analyzed using Rasch analysis, chi square and a general linear model. Moreover, Differential Item Functioning (DIF) was investigated. The hierarchy of ETs' level of challenge was generally stable in the two contexts. On group-level, the relevance was somewhat higher and the perceived ability to use ET significantly higher in the Swedish sample than in the Japanese. The similarities and differences between the technological landscapes of Sweden and Japan could be detected by ETUQ, demonstrating its usefulness in both countries. The potential causes to the differences in relevance of and perceived ability to use ET between older adults in Sweden and Japan need further exploration.

    This report presents the findings of a group of database experts, sponsored by the Japanese Technology Evaluation Center (JTEC), based on an intensive study trip to Japan during March 1991. Academic, industrial, and governmental sites were visited. The primary findings are that Japan is supporting its academic research establishment poorly, that industry is making progress in key areas, and that both academic and industrial researchers are well aware of current domestic and foreign technology. Information sharing between industry and academia is effectively supported by governmental sponsorship of joint planning and review activities, and enhances technology transfer. In two key areas, multimedia and object-oriented databases, the authors can expect to see future export of Japanese database products, typically integrated into larger systems. Support for academic research is relatively modest. Nevertheless, the senior faculty are well-known and respected, and communicate frequently and in depth with each other, with government agencies, and with industry. In 1988 there were a total of 1,717 Ph.D.`s in engineering and 881 in science. It appears that only about 30 of these were academic Ph.D.`s in the basic computer sciences.

    Most of major nucleonic gauges in Japan have already passed the period of saturation in number of use in big industries. On the other hand, however, small gauges with low activity sources are expected to increasingly diffuse into smaller industries. There have been so far more unique gauges and more interesting applications in small gauges using low activity sources, which are free from legal regulation. Still at present new applications with advanced technology are being developed using such small sources. Description is given on the current status of nucleonic gauges with emphasis on development of new techniques and applications. (author)

    As part of a study of nuclear power development in Japan and the United States, surveys of perceptions of risk toward 30 activities, substances, and technologies have been carried out in the Pacific Northwest and Tokyo, Japan. The results show that people in both countries have the highest level of dread toward nuclear waste disposal, nuclear accidents, and nuclear war, greater even than their dread of crime and AIDS. In addition to comparisons of dread, the paper also discusses similarities and differences between Japanese and American responses for other dimensions of risk perception. 15 refs., 5 figs., 2 tabs

    International Nuclear Information System (INIS)

    2012-01-01

    To strengthen global nuclear safety, the IAEA Action Plan on Nuclear Safety (1) recommends the use of IAEA technical peer review services for plant safety, in the light of the accident at TEPCO's Fukushima Dai-ichi Nuclear Power Plant, and (2) encourages that Member States promptly use IAEA review services to gather and disseminate information on the performance of their nuclear power plants (NPPs) and the performance of the designed protective measures against site specific extreme natural hazards and to utilize the lessons learned in the enhancement of NPP safety worldwide. The Government of Japan and the IAEA have concurred to deploy a mission to Onagawa Nuclear Power Station (NPS), owned and operated by Tohoku Electric Power Co., Inc. (Tohoku EPCo), with the objective of gathering information, during the course of a two-week period on site. This included collecting data on the performance of the structures, systems and components of the Onagawa NPS, in the 11 March 2011 Great East Japan Earthquake (GEJE) and its major aftershocks, as well as compiling the information gathered in a seismic experience database for future use by the Member States to gauge the performance of their facilities against external hazards. The Onagawa NPS has three boiling water reactors (units); with the first unit operating for the last twenty-eight years. Unit 1 began commercial operation in June 1984. Unit 2 began commercial operation in July 1995 and Unit 3 began commercial operation in January 2002. The three units have a combined electric generation capacity of 2,174 Megawatts. Situated on the eastern coast of Japan facing the Pacific Ocean, the Onagawa NPS was the closest nuclear power station to the epicentre of the enormous M9.0 GEJE. Due to its proximity to the earthquake source, the plant experienced very high levels of ground motion -the strongest shaking that any nuclear power plant has ever experienced from an earthquake. The plant shut down safely. The mission objective

    We examined the activities of home care supporting clinics (HCSC) in Tokyo, Japan, from the standpoint of the place of death. The number of HCSCs in Tokyo was 1,246 in 2010. Fifteen HCSCs cared for > or = 50 patients who died at home in a year. In contrast, the 19 HCSCs in the top 10 percentile for the number of patients (> or = 176) did not have any patients who died at home. Their patients died at hospitals or facilities. These results suggest that the activities of HCSCs in Tokyo are diverse.

    Our survey assessed the use of advanced radiotherapy technologies at the designated cancer care hospitals in Japan, and we identified several issues to be addressed. We collected the data of 397 designated cancer care hospitals, including information on staffing in the department of radiation oncology (e.g. radiation oncologists, medical physicists and radiation therapists), the number of linear accelerators and the implementation of advanced radiotherapy technologies from the Center for Cancer Control and Information Services of the National Cancer Center, Japan. Only 53% prefectural designated cancer care hospitals and 16% regional designated cancer care hospitals have implemented intensity-modulated radiotherapy for head and neck cancers, and 62% prefectural designated cancer care hospitals and 23% regional designated cancer care hospitals use intensity-modulated radiotherapy for prostate cancer. Seventy-four percent prefectural designated cancer care hospitals and 40% regional designated cancer care hospitals employ stereotactic body radiotherapy for lung cancer. Our multivariate analysis of prefectural designated cancer care hospitals which satisfy the institute's qualifications for advanced technologies revealed the number of radiation oncologists (P=0.01) and that of radiation therapists (P=0.003) were significantly correlated with the implementation of intensity-modulated radiotherapy for prostate cancer, and the number of radiation oncologists (P=0.02) was correlated with the implementation of stereotactic body radiotherapy. There was a trend to correlate the number of medical physicists with the implementation of stereotactic body radiotherapy (P=0.07). Only 175 (51%) regional designated cancer care hospitals satisfy the institute's qualification of stereotactic body radiotherapy and 76 (22%) satisfy that of intensity-modulated radiotherapy. Seventeen percent prefectural designated cancer care hospitals and 13% regional designated cancer care hospitals

    Older adults' ever-improving health and changing lifestyles necessitate the development of a scale that can better measure their competence at a higher level. We developed the Japan Science and Technology Agency Index of Competence (JST-IC) via item analysis and assessed its psychometric properties. Participants were 1306 community-dwelling older adults (623 men and 683 women, 74.0 ± 2.8 years old) who completed the 54-item draft JST-IC to determine their level of independence. Three procedures (including item selection, factor analyses, and reliability and validity analyses) were conducted to finalize the JST-IC and evaluate its psychometric properties. The item selection resulted in exclusion of 26 items for the following reasons: (a) 15 because of very high ratios (80% or more) of responders who answered "yes", (b) one because of gender differences (phi coefficient = 0.34), (c) five because of their weak association with the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC) (Pearson correlation coefficient of 0.30 or smaller), and (d) five because of redundancy of meaning with other items. Through factor analyses, we selected 16 items with a four-factor solution for the final version. JST-IC score exhibited a near-normal distribution and significant gender and age differences, and had moderate correlations with size of social network and level of subjective well-being and strong correlations with TMIG-IC score, physical fitness, and health literacy. The JST-IC is useful for assessing competence at a higher level in community-dwelling older adults.

    Health technology assessment (HTA) has been continuously used for value-based healthcare decisions over the last decade. Healthcare databases represent an important source of information for HTA, which has seen a surge in use in Western countries. Although HTA agencies have been established in Asia-Pacific region, application and understanding of healthcare databases for HTA is rather limited. Thus, we reviewed existing databases to assess their potential for HTA in Thailand where HTA has been used officially and Japan where HTA is going to be officially introduced. Existing healthcare databases in Thailand and Japan were compiled and reviewed. Databases' characteristics e.g. name of database, host, scope/objective, time/sample size, design, data collection method, population/sample, and variables were described. Databases were assessed for its potential HTA use in terms of safety/efficacy/effectiveness, social/ethical, organization/professional, economic, and epidemiological domains. Request route for each database was also provided. Forty databases- 20 from Thailand and 20 from Japan-were included. These comprised of national censuses, surveys, registries, administrative data, and claimed databases. All databases were potentially used for epidemiological studies. In addition, data on mortality, morbidity, disability, adverse events, quality of life, service/technology utilization, length of stay, and economics were also found in some databases. However, access to patient-level data was limited since information about the databases was not available on public sources. Our findings have shown that existing databases provided valuable information for HTA research with limitation on accessibility. Mutual dialogue on healthcare database development and usage for HTA among Asia-Pacific region is needed.

    Prior research has indicated that pollen might be linked to suicide mortality although the few studies that have been undertaken to date have produced conflicting findings and been limited to Western settings. This study examined the association between the level of airborne pollen and suicide mortality in Tokyo, Japan in the period from 2001 to 2011. The daily number of suicide deaths was obtained from the Japanese Ministry of Health, Labour and Welfare, with pollen data being obtained from the Tokyo Metropolitan Institute of Public Health. A time-stratified case-crossover study was performed to examine the association between different levels of pollen concentration and suicide mortality. During the study period there were 5185 male and 2332 female suicides in the pollen season (February to April). For men there was no association between airborne pollen and suicide mortality. For women, compared to when there was no airborne pollen, the same-day (lag 0) pollen level of 30 to Tokyo. Copyright © 2017 Elsevier Inc. All rights reserved.

    Munich Re once ranked that Tokyo metropolitan region, the capital of Japan, is the most vulnerable area for earthquake disasters, followed by San Francisco Bay Area, US and Osaka, Japan. Seismologists also predict that Tokyo metropolitan region may have at least one near-field earthquake with a probability of 70% for the next 30 years. Given this prediction, Japanese Government took it seriously to conduct damage estimations and revealed that, as the worst case scenario, if a7.3 magnitude earthquake under heavy winds as shown in the fig. 1, it would kill a total of 11,000 people and a total of direct and indirect losses would amount to 112,000,000,000,000 yen(1,300,000,000,000, 1=85yen) . In addition to mortality and financial losses, a total of 25 million people would be severely impacted by this earthquake in four prefectures. If this earthquake occurs, 300,000 elevators will be stopped suddenly, and 12,500 persons would be confined in them for a long time. Seven million people will come to use over 20,000 public shelters spread over the impacted area. Over one millions temporary housing units should be built to accommodate 4.6 million people who lost their dwellings. 2.5 million people will relocate to outside of the damaged area. In short, an unprecedented scale of earthquake disaster is expected and we must prepare for it. Even though disaster mitigation is undoubtedly the best solution, it is more realistic that the expected earthquake would hit before we complete this business. In other words, we must take into account another solution to make the people and the assets in this region more resilient for the Tokyo metropolitan earthquake. This is the question we have been tackling with for the last four years. To increase societal resilience for Tokyo metropolitan earthquake, we adopted a holistic approach to integrate both emergency response and long-term recovery. There are three goals for long-term recovery, which consists of Physical recovery, Economic

    The international nature of science and engineering research demands that students have the skillsets necessary to collaborate internationally. However, limited options exist for science and engineering undergraduates who want to pursue research abroad. The NanoJapan International Research Experience for Undergraduates Program is an innovative response to this need. Developed to foster research and international engagement among young undergraduate students, it is funded by a National Science Foundation Partnerships for International Research and Education (PIRE) grant. Each summer, NanoJapan sends 12 U.S. students to Japan to conduct research internships with world leaders in terahertz (THz) spectroscopy, nanophotonics, and ultrafast optics. The students participate in cutting-edge research projects managed within the framework of the U.S-Japan NSF-PIRE collaboration. One of our focus topics is THz science and technology of nanosystems (or `TeraNano'), which investigates the physics and applications of THz dynamics of carriers and phonons in nanostructures and nanomaterials. In this article, we will introduce the program model, with specific emphasis on designing high-quality international student research experiences. We will specifically address the program curriculum that introduces students to THz research, Japanese language, and intercultural communications, in preparation for work in their labs. Ultimately, the program aims to increase the number of U.S. students who choose to pursue graduate study in this field, while cultivating a generation of globally aware engineers and scientists who are prepared for international research collaboration.

    2014-06-01

    Using interviews, participant observation, and published documents, this article analyzes the co-construction of robotics and culture in Japan through the technical discourse and practices of robotics researchers. Three cases from current robotics research--the seal-like robot PARO, the Humanoid Robotics Project HRP-2 humanoid, and 'kansei robotics' - show the different ways in which scientists invoke culture to provide epistemological grounding and possibilities for social acceptance of their work. These examples show how the production and consumption of social robotic technologies are associated with traditional crafts and values, how roboticists negotiate among social, technical, and cultural constraints while designing robots, and how humans and robots are constructed as cultural subjects in social robotics discourse. The conceptual focus is on the repeated assembly of cultural models of social behavior, organization, cognition, and technology through roboticists' narratives about the development of advanced robotic technologies. This article provides a picture of robotics as the dynamic construction of technology and culture and concludes with a discussion of the limits and possibilities of this vision in promoting a culturally situated understanding of technology and a multicultural view of science.

    This paper describes the condensate demineralizing equipment recently supplied to the second, third, and fifth power units of the Fukushima Daiichi Nuclear Power Station of the Tokyo Electric Power Company, Inc. The output of this equipment is rated as 4,900 m 3 /h each, which is currently the largest capacity for this type of equipment in Japan. The purpose of this equipment is to remove any ion components and suspended solids contained in condensate to improve its water purity. By doing so, decreasing the corrosion rate of materials used in the plant and, at the same time, decreasing the radioactivity of the condensate, thus easing the whole plant operation can be achieved. The same kind of equipment is also employed at the conventional thermal power stations, but the required functioning and operating mode are quite different. In the case of the nuclear power plant, extremely severe requirements specific with nuclear technology must be met which arise solely from dealing with radioactive substances. Not only the water treatment method, but also layout and arrangement, operation and liquid waste processing methods differ from those for the conventional power plants. The equipment for the sixth unit at Fukushima is now under designing and that for the Tokai No.2 unit of the Japan Atomic Power Company is already under shop fabrication. Both have the rated capacity of 7,300 m 3 /h each, which exceeds far up the capacity of the previously mentioned equipment. (auth.)

    The need for domiciliary dental care has increased with the aging of Japanese society. The Tokyo Metropolitan Government and Tokyo Dental Association conducted a survey of dental institutions within Tokyo in order to clarify which factors influenced implementation of domiciliary dental care by dental institutions. The proportion was significantly higher in (1) dentists in their 50s or older, (2) those working in cooperation with primary care physicians, (3) those providing dysphagia rehabilitation, (4) those who give information on prevention of aspiration pneumonia, (5) those who attended training on medical or domiciliary dental care for the elderly in need of nursing care, and (6) those who attended training workshops and seminars provided by the Tokyo Dental Association in 2010. In the logistic regression analysis, a significant odds ratio was obtained for the same items, excluding age. Attendance at training on medical or domiciliary dental care for the elderly in need of nursing care had the highest odds ratio. Those who attended any kind of training course implemented domiciliary dental care significantly more often. Training conducted by the Tokyo Metropolitan Center for Oral Health of Persons with Disabilities, Tokyo Dental Association, and local dental associations showed a significant odds ratio, with the highest by the Tokyo Dental Association. Traditionally, education on domiciliary dental care in the elderly is not provided at the college level. The present results indicate the importance of educating students with regard to the unique challenges such work poses. Attending seminars hosted by the Tokyo Dental Association also significantly influenced implementation of domiciliary dental care. This seems to be an important result, suggesting the effectiveness of training provided by dental associations with regard to the promotion of domiciliary dental care. This indicates the need for dental associations to provide such training throughout Japan.

  19. JSFR: Japan's challenge towards the competitive SFR design concept with innovative technologies

    2006-01-01

    JSFR is a sodium-cooled, MOX(or metal) fuelled, advanced loop type fast reactor design concept conducting by Japan Atomic Energy Agency(JAEA) through the Feasibility Study on commercialized Fast Reactor(FR) Cycle Systems with participation of all parties concerned in Japan since 1999. The economic competitiveness is one of the crucial points and has been emphasized in the design study of JSFR. One of the ways for less construction cost is the compact NSSS design by introducing the following innovative technologies; Shortening the piping length, simplified configuration with the inverse L-shaped-pipes and a two-loop system even for a l,500MWe power plant, by adopting high chromium steel with lower thermal expansion and higher strength, Upgrading of the structural design standards at elevated temperature for sodium-cooled FR system, and Development of an integrated intermediate heat exchanger (IHX) with a mechanical pump. The other way is introducing passive decay heat removal system with natural circulation. The elimination of active components such as pony motors and blowers leads to reduction of the capacity of the BOP system such as electricity supply system, emergency DGs, HVAC system and component cooling water system. In order to attain lower power generation cost, not only less construction cost but also less operational cost including fuel cycle cost is crucial. Therefore higher burn-up of the averaged core, more than 150GWd/t, has been applied by introducing ODS steel cladding material. As a result, it is confirmed that the JSFR design concept is well suited to the development target equivalent to l,000USD/kWe (as NOAK, overnight cost), while ensuring safety. The most of the cost reduction comes from the innovative technologies. The R and D plan of these technologies was summarized as a roadmap and the R and D efforts are on going for establishing a technical scheme of FR cycle systems by around 2015

    In central Japan, the Philippine Sea plate (PSP) subducts beneath the Tokyo metropolitan region. Devastating M8-class earthquakes occurred on the upper surface of the Philippine Sea plate (SPS), examples of which are the Genroku earthquake of 1703 (magnitude M=8.0) and the Kanto earthquake of 1923 (M=7.9), which had 105,000 fatalities. A M7 or greater (M7+) earthquake in this region at present has high potential to produce devastating loss of life and property with even greater global economic repercussions although it is smaller than the megathrust type M8-class earthquakes. This great earthquake is evaluated to occur with a probability of 70 % in 30 years by the Earthquake Research Committee of Japan. The M7+ earthquakes may occur either on the upper surface or intra slab of PSP. The Central Disaster Management Council of Japan estimates the next great M7+ earthquake will cause 11,000 fatalities and 112 trillion yen (1 trillion US$) economic loss at worst case if it occur beneath northern Tokyo bay with M7.3. However, the estimate is based on a source fault model by conventional studies about the PSP geometry. To evaluate seismic hazard due to the great quake we need to clarify the geometry of PSP and also the Pacific palate (PAP) that subducs beneath PSP. We identify those plates with use of seismic tomography and available deep seismic reflection profiling and borehole data in southern Kanto area. We deployed about 300 seismic stations in the greater Tokyo urban region under the Special Project for Earthquake Disaster Mitigation in Tokyo Metropolitan Area. We obtain clear P- and S- wave velocity (Vp and Vs) tomograms which show a clear image of PSP and PAP. A depth to the top of PSP, 20 to 30 kilometer beneath northern part of Tokyo bay, is about 10 km shallower than previous estimates based on the distribution of seismicity (Ishida, 1992). This shallower plate geometry changes estimations of strong ground motion for seismic hazards analysis within the Tokyo

    This paper treats technology readiness level (TRL) assessment of Partitioning and Transmutation (P-T) toward closed fuel cycle in JAPAN. The purpose is providing clarified information related to the current maturity of the partitioning and transmutation technologies by applying the methodology of TRL, parallel to attempting to establish common indications among relating technology area. The methodology should be one of useful communication tools between specialists and management level, and also among countries interested in the P-T technologies. The generic TRL in this study is based on the GNEP (Global Nuclear Energy Partnership)'s definition: TRL 3 shows the status that critical function is proved and elemental technologies are identified, TRL 4 represents that relating technologies are validated at bench scale in laboratory environment, and TRL 5 achieves the completion of development related to the subsystem and elemental technologies. Detailed indications are established through discussion of the relating specialists. Reviewed technological area includes P-T and minor actinide (MA) cycle: Fast Breeder Reactor (FBR) and Accelerator driven system (ADS) for MA transmutation, partitioning processes, and MA-bearing fuels. The assessments reveal that TRL spreads around TRL 3 to TRL 4 because each system requires more the development of elemental technologies. Transmutation core of FBR is assessed to be TRL 4 in that MA bearing integral test is required additionally, and ADS becomes TRL 3 because the elemental technologies were identified and the requirements were specified. Consequently, the common key issue is how the nuclear calculation methodology will be validated for MA-bearing-fuelled core, since several percentages of MA changes the void reactivity and the Doppler Effect significantly, which are inherently important in reactor safety. It should be that critical experiments with several kg of americium or more are difficult in the existing experimental

    The objective of this work is to validate the technical targets in the governmental hydrogen energy road-map of Japan by analyzing market penetration of fuel cell vehicle(FCV)s and effects of fuel price and carbon tax on it from technology competition point of view. In this analysis, an energy system model of Japan based on MARKAL is used. The results of the analysis show that hydrogen FCVs could not have cost-competitiveness until 2030 without carbon tax, including the governmental actual plan of carbon tax. However, as the carbon tax rate increases, instead of conventional vehicles including gasoline hybrid electric vehicle, hydrogen FCVs penetrate to the market earlier and more. By assuming higher fuel price and severer carbon tax rate, market share of hydrogen FCVs approaches to the governmental goal. This suggests that cheaper vehicle cost and/or hydrogen price than those targeted in the road-map is required. At the same time, achievement of the technical targets in the road-map also allows to attain the market penetration target of hydrogen FCVs in some possible conditions. (authors)

    Japan has the largest number of psychiatric beds in the world and has been in the process of deinstitutionalization since 2004. The majority of psychiatric inpatients are elderly long-term patients, who are at risk of homelessness after they are discharged. There is little information about homeless people with mental illnesses in Japan, and the aim of this study was to describe characteristics of people with a mental illness in homeless shelters in Tokyo. A face-to-face survey was conducted from December 2012 to March 2013 by the staff of a nonprofit organization (NPO) that helps socially isolated persons. Of the 1,056 people who received help during the study period, 684 completed the survey. Eighteen percent of the 684 survey participants had a mental illness. Of the 210 individuals who lived in shelters, one-third had a mental illness. The mean age of shelter users with mental illness was 64.9; they tended to be referred from hospitals, and their mental well-being was poorer than other NPO service users in the study. Among the service users with mental illness, those living in shelters were older than those living in the community and more likely to have a history of trouble with alcohol, poor family relationships, and impaired instrumental activities of daily living. Unmet mental health needs were noted among discharged hospital patients living in Tokyo homeless shelters. An integrated and community-based support system with more effective health care delivery, including critical time interventions, is needed.

    A revised estimation has been made of the local air quality improvement that can be achieved in Tokyo as a byproduct of a word-wide hydrogen energy economy based on global reduction of CO2 emission from fossil fuels. The study for the WE-NET Project in Japan examined the potential for reduction in nitrogen oxide emission with hydrogen fuel in the Tokyo metropolitan area where sufficient data exist on trends in population, vehicle registrations, traffic activity, and exhaust emissions. A dynamic model was developed to extrapolate the trends in these data to estimate future NOx emission rates in comparison to regulatory scenarios based on policy and technical decisions of the Tokyo Metropolitan Government for improvement of air quality in the metropolitan area. The results of the model show significant potential for reduction of NOx emission by the year 2020 with a concomitant reduction in mean roadside NOx concentration. (author)

  7. THE SPATIAL DEVIATION OF CONCENTRATED HEAVY RAIN IN TOKYO - USING DETAILED URBAN GEOMETRIC DATA -

    Unusual weather, such as urban localized heavy rain, has become a serious problem lately due to the disasters caused by it. In this work, the latest data of Tokyo, Japan is used with past ones to see the dramatic change in urban geometry and to understand the spatial anomaly of concentrated heavy rain in summer time. As a result, the urban geometry in Tokyo has indeed grown. Adding the displacement height to actual elevation gives the "affective" elevation, which is very low along the bay and abruptly increases as it approaches the western areas. This sudden increase in elevation seems to correspond with where the anomaly of rainfall for concentrated heavy rain becomes positive. In addition, the 9-year data from the River Bureau shows the shift of positive anomaly into the urban area. Finally, the spatial deviation, driven by the Amesh data, indicates the strong relationship between urbanization and precipitation in Tokyo.

    The Japan Society of Obstetrics and Gynecology (JSOG) implemented an assisted reproductive technology (ART) registry system in 1986. Here are reported the characteristics and treatment outcomes of ART cycles that were registered in 2015. JSOG has requested all participating ART facilities to register cycle-specific information for all ART cycles since 2007. A descriptive analysis was performed by using the registry database for 2015. In total, 424 151 cycles and 51 001 neonates (1 in 19.7 neonates born in Japan) were registered in 2015. The patients' mean age was 38.2 years (standard deviation = 4.5). Among the fresh cycles, 94 158 of 244 718 (38.5%) egg retrieval cycles were cycles with freeze-all embryos or oocytes, while fresh embryo transfer (ET) was performed in 70 254 cycles, signaling a decrease from 2014. There were 169 898 frozen-thawed ET cycles, resulting in 56 355 pregnancies and 40 599 neonates. Single ET was performed at a rate of 79.7% for fresh and 81.8% for frozen cycles and the singleton pregnancy/live birth rates were 96.9%/96.5% and 96.8%/96.4% for the respective cycles. The total ART cycles and live births resulting from ART has been increasing in Japan. Single ET was performed at a rate of almost 80% and ET cycles have shifted from fresh to frozen cycles.

    Fusion community does not appreciate vacuum technologies to the same extent as accelerator community does. This is because, in the case of accelerators, in particular storage ring systems, the requirement of attaining ultrahigh vacuum in order to avoid collisional loss is well defined, on the other hand, it is not possible to define the requirement so precisely in the case of fusion devices. One of the reasons is that core plasma interacts with vessel wall so strongly and unpredictably that it becomes difficult to identify the role played by individual components. However, in the next step and the next generation machines like CIT, LHS, ITER, FER and NET, vacuum technologies would play more significant roles, because the CIT will introduce tritium in a vacuum vessel, and the aim of the ITER project is to demonstrate particle balance, namely, to achieve steady state operation with D-T fuel. The Japan-U.S. workshop P-118 was held at the Institute of Plasma Physics, Nagoya University, from August 1 to 5, 1988. 33 participants including 4 from the U.S. took part in the workshop. In the plenary session, 12 lectures were given, and also the topics-oriented session on pumping, gauging, remote maintenance, first wall, pump limiter, divertor and others was held. (K.I.)

    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.

    In Japan, as the construction of new landfill facilities has become extremely difficult and the number of sites procured for landfill construction has decreased due to the 'not in my back yard' (NIMBY) syndrome, it has been assumed that the adoption of new technologies has increased. As the performance of new technologies exceeds that of conventional technologies, it is also assumed that residents would prefer the use of these new technologies and therefore any construction plans should be devised to ensure their use to ensure residents' satisfaction. In the present study, the technologies adopted for municipal solid waste landfill facilities constructed in recent years (2000 to 2004) in Japan and the bases for their adoption were investigated by means of a questionnaire survey. One of the main bases for the adoption of new technologies was the request by residents for new technology for roofing, rather than the other for new technologies for barrier systems, leachate treatment, and monitoring. In addition, it is possible that the municipalities did not recognize the difference between conventional and new technologies as defined in this study. The roof-type landfill that isolates waste from the surrounding environment was one of the requirements for the construction of new landfill facilities identified in the present investigation, and in this regard waste isolation should be required in all circumstances.

    Some evidence suggests an association may exist between the level of air pollution and suicide mortality. However, this relation has been little studied to date. The current study examined the association in Tokyo, Japan. Suicide mortality data for Tokyo for the 11-year period 2001-2011 were obtained together with data on four air pollutants: fine particulate matter (PM2.5), suspended particulate matter (SPM), sulphur dioxide (SO2) and nitrogen dioxide (NO2). A time-stratified case-crossover study design was used to examine the daily association between the level of air pollution and suicide mortality. During the study period there were 29,939 suicide deaths. In stratified analyses an interquartile range (IQR) increase in the same-day concentration of NO2 was linked to increased suicide mortality among those aged under 30 (percentage change: 6.73%, 95% CI: 0.69-13.12%). An IQR increase in PM2.5 and SO2 was associated with a 10.55% (95% CI: 2.05-19.75%) and 11.47% (95% CI: 3.60-19.93%) increase, respectively, in suicide mortality among widowed individuals for mean exposure on the first four days (average lags 0-3). Positive associations were observed for the air pollutants in the summer although associations were reversed in autumn. We relied on monitoring data to approximate individual exposure to air pollutants. Higher levels of air pollution are associated with increased suicide mortality in some population subgroups in Tokyo. Further research is needed to elucidate the mechanisms linking air pollutants and suicide in this setting. Copyright © 2016 Elsevier B.V. All rights reserved.

    According to World Bank Report, more than half of the world’s population is now living in cities and over two-thirds of greenhouse gas emissions come from cities worldwide. The Kanto Plain is the largest plain in Japan, which experienced the greatest urban expansion in the 20th century. Satellite images collected over a span of years can be used to identify and characterize both natural and anthropogenic changes over large areas of land. Landsat satellite images are ideal for this purpose; imagery recorded over nearly four decades provides a unique resource for temporal analysis of urban area land cover change. The purpose of this study was to investigate spatial and temporal urban area changes in the Tokyo Metropolitan Area (include the neighboring regions). and to investigate the possible causes of those changes. To do this, we applied land-cover classification schemes to Multispectral Scanner (MSS), Thematic Mapper (TM), and Enhanced Thematic Mapper Plus (ETM+) sensor images recorded between 1972 and 2002, which we acquired from the Landsat archive. We used two supervised classification methods, the self-organizing map (SOM) neural network method and the subspace method, to accurately classify land cover on Landsat images recorded in 1972, 1985, and 2002. This allowed us to quantitatively present urban area changes between 1972 and 2002, and allowed us to analyze its relation with multi-time 1 kilometer grid population density census data to further report on the trends of urban expansion. Figure 1 shows the urban area in 1972, and figure 2 shows the urban area in 2002. From the two maps, along with the high economic growth of the Japanese economy, the concentration of the population in Tokyo extremely increased over the period from 1972 to 2002. As a result, these factors lead to urban sprawl in the suburban areas of Tokyo Metropolitan Area. Figure 1. Urban area in 1972. Figure 2. Urban area in 2002.

    The Japan Society of Obstetrics and Gynecology implemented a registry report system for the clinical practice of assisted reproductive technology in 1986. The aggregated results from 1992 to 2014 are reported herein. The total number of registered treatments was 393 745 cycles, of which 66 550 were pregnancy cycles and 46 008 were cycles with a live birth. Compared to the number of registered treatments in 2008, when the cycle-based registry was newly introduced, there was a 2.07-fold increase in the total number of treatments and a 2.25-fold increase in the number of cycles with a live birth. As the average age of patients who receive assisted reproductive technology has become markedly higher year by year, the most common age of those patients who received assisted reproductive technology in 2014 was 40 years. The total numbers of both assisted reproductive technology treatments and assisted reproductive technology live births are likely to be higher in the future. In addition, the trend toward aging patients seems to be continuing into the future.

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

    Aim This study clarified the characteristics of life habits of obese Japanese male students at the National Colleges of Technology, Japan. Materials and methods Healthy students aged 15-19 years answered a questionnaire containing 21 items on the following five categories of life habits: general exercise, meals, sleeping, leisure activity and illness or injury history. The subjects were divided into three groups based on the criteria of body mass index (BMI) and body fat percentage (%BF): non-obese (%BF time, bedtime and amount of time spent walking, sleeping and watching TV per day were examined using one-way analysis of variance (ANOVA) and chi-square tests for each item. Results The overweight obese and hidden obese groups engaged in less exercise time, were more likely to eat until they were full at meals and were less likely to eat between meals or late at night than the non-obese group. In addition, the non-obese group had significantly later waking times and significantly less TV-watching time than the overweight obese group. There were no significant differences with respect to leisure activity and illness or injury history among the three groups. Many students in all groups had regular waking times and were not performing any leisure activities. Conclusion The findings suggest that obese students may need further guidance to help them maintain a healthy life and appropriate weight.

    2008-01-01

    On 16 July 2007, a strong earthquake, the Niigataken Chuetsu-oki earthquake, with a moment magnitude of 6.6 (M JMA =6.8 according to the Japanese Meteorological Agency), occurred at 10:13 h local time with its hypocentre below the seabed of the Jo-chuetsu area in Niigata prefecture (37 deg. 33' N, 138 deg. 37'E) in Japan, affecting the Kashiwazaki-Kariwa Nuclear Power Plant (NPP) located approximately 16 km south of its epicentre. Kashiwazaki-Kariwa NPP is the biggest nuclear power plant site in the world. It is located in the Niigata prefecture, in the northwest coast of Japan, and it is operated by Tokyo Electric Power Company (TEPCO). The site has seven units with a total of 7965 MW net installed capacity. Five reactors are of BWR type and two reactors are of ABWR type. The five BWR units entered commercial operation between 1985 and 1994 and the two ABWRs in 1996 and 1997, respectively. Following this event, the Government of Japan through the Nuclear and Industrial Safety Agency (NISA) requested the IAEA to carry out a fact finding mission with the main purpose of identifying the preliminary findings and lessons learned from this event in order to share them with the international nuclear community. This first mission took place from 6 - 10 August 2007 and the mission report of the August 2007 mission is available on the IAEA web page http://www.iaea.org. The purpose of the second IAEA mission was to conduct - six months after the event - a follow-up of the preliminary findings of the August 2007 mission on the basis of the results available in January 2008 of the related studies and investigations performed. In accordance with the terms of reference for the follow-up mission and the availability of results from the performed studies and investigations, the scope of the follow-up mission focussed on three subject areas: (1) seismic design basis - design basis ground motions, including the evaluation of the seismic hazard ; (2) plant behaviour - integrity

    Japan and the United States signed in 1968 a new atomic energy agreement through which US light-water nuclear reactors, including those of the Fukushima Daiichi Nuclear Power Plant of Tokyo Electric Power Company, were to be introduced into Japan. This paper studies the history of negotiations for the 1968 agreement using documents declassified in the 1990s in the US and Japan. After the success of the Chinese nuclear test in October 1964, the United States became seriously concerned about nuclear armament of other countries in Asia including Japan. Expecting that Japan would not have its own nuclear weapons, the US offered to help the country to demonstrate its superiority in some fields of science including peaceful nuclear energy to counter the psychological effect of the Chinese nuclear armament. Driven by his own political agenda, the newly appointed Prime Minister Eisaku Sato responded to the US expectation favorably. When he met in January 1965 with President Johnson, Sato made it clear that Japan would not pursue nuclear weapons. Although the US continued its support after this visit, it nevertheless gave priority to the control of nuclear technology in Japan through the bilateral peaceful nuclear agreement. This paper argues that the 1968 agreement implicitly meant a strategic measure to prevent Japan from going nuclear and also a tactic to persuade Japan to join the Nuclear Non -Proliferation Treaty.

    The Tokyo Tier2 center, which is located at the International Center for Elementary Particle Physics (ICEPP) in the University of Tokyo, was established as a regional analysis center in Japan for the ATLAS experiment. The official operation with WLCG was started in 2007 after the several years development since 2002. In December 2012, we have replaced almost all hardware as the third system upgrade to deal with analysis for further growing data of the ATLAS experiment. The number of CPU cores are increased by factor of two (9984 cores in total), and the performance of individual CPU core is improved by 20% according to the HEPSPEC06 benchmark test at 32bit compile mode. The score is estimated as 18.03 (SL6) per core by using Intel Xeon E5-2680 2.70 GHz. Since all worker nodes are made by 16 CPU cores configuration, we deployed 624 blade servers in total. They are connected to 6.7 PB of disk storage system with non-blocking 10 Gbps internal network backbone by using two center network switches (NetIron MLXe-32). The disk storage is made by 102 of RAID6 disk arrays (Infortrend DS S24F-G2840-4C16DO0) and served by equivalent number of 1U file servers with 8G-FC connection to maximize the file transfer throughput per storage capacity. As of February 2013, 2560 CPU cores and 2.00 PB of disk storage have already been deployed for WLCG. Currently, the remaining non-grid resources for both CPUs and disk storage are used as dedicated resources for the data analysis by the ATLAS Japan collaborators. Since all hardware in the non-grid resources are made by same architecture with Tier2 resource, they will be able to be migrated as the Tier2 extra resource on demand of the ATLAS experiment in the future. In addition to the upgrade of computing resources, we expect the improvement of connectivity on the wide area network. Thanks to the Japanese NREN (NII), another 10 Gbps trans-Pacific line from Japan to Washington will be available additionally with existing two 10 Gbps lines

    Abuse of illegal drugs is widespread among young people, especially in the so-called "dance club scene" or "rave scene". Severe and even fatal poisonings have been attributed to the consumption of such drugs of abuse. The actions against these drugs by the Tokyo Metropolitan Government and subsequently by the Government of Japan have gone some way to reducing the potential harm caused by these substances. However, alternative products have been advertised on a number of websites. During our careful surveillance of illegal drugs in 2011, we found seven unregulated drugs advertised. This means that we have an obligation to continue strict surveillance of illegal drugs and to structure a system of temporary bans on illegal drugs.

    Remote handling technology has been systematically developed for nuclear fuel cycle facilities in Japan since 1970s, primarily in parallel with the development of reprocessing and HLLW (High Level Liquid Waste) vitrification process. In case of reprocessing and vitrification process to handle highly radioactive and hazardous materials, the most of components are installed in the radiation shielded hot cells and operators are not allowed to enter the work area in the cells for operation and maintenance. Therefore, a completely remote handling system is adopted for the cells to reduce radiation doses of operators and increase the availability of the facility. The hot cells are generally designed considering the scale of components (laboratory, demonstration, or full-scale), the function of the systems (chemical process, material handling, dismantling, decontamination, or chemical analysis), and the environmental conditions (radiation dose rate, airborne concentration, surface contamination, or fume/mist/dust). Throughout our domestic development work for remote handling technology, the concept of the large scale integrated cell has been adopted rather than a number of small scale separated cells, for the reasons to reduce the total installation space and the number of remote handling equipment required for the each cell as much as possible. In our domestic remote maintenance design, several new concepts have been developed, tested, and demonstrated in the Tokai Virtrification Facility (TVF) and the Rokkasho HLLW Vitrification and Storage Facility (K-facility). Layout in the hot cells, the performance of remote handling equipment, and the structure of the in-cell components are important factors for remote maintenance design. In case of TVF (hot tests started in 1995), piping and vessels are prefabricated in the rack modules and installed in two lines on both sides of the cell. These modules are designed to be remotely replaced in the whole rack. Two overhead cranes

    This paper presents results of conceptual design activities and associated R&D of a solid breeder blanket system for demonstration of power generation fusion reactors (DEMO blanket) cooled by supercritical water. The Fusion Council of Japan developed the long-term research and development programme of the blanket in 1999. To make the fusion DEMO reactor more attractive, a higher thermal efficiency of more than 40% was strongly recommended. To meet this requirement, the design of the DEMO fusion reactor was carried out. In conjunction with the reactor design, a new concept of a solid breeder blanket cooled by supercritical water was proposed and design and technology development of a solid breeder blanket cooled by supercritical water was performed. By thermo-mechanical analyses of the first wall, the tresca stress was evaluated to be 428 MPa, which clears the 3Sm value of F82H. By thermal and nuclear analyses of the breeder layers, it was shown that a net TBR of more than 1.05 can be achieved. By thermal analysis of the supercritical water power plant, it was shown that a thermal efficiency of more than 41% is achievable. The design work included design of the coolant flow pattern for blanket modules, module structure design, thermo-mechanical analysis and neutronics analysis of the blanket module, and analyses of the tritium inventory and permeation. Preliminary integration of the design of a solid breeder blanket cooled by supercritical water was achieved in this study. In parallel with the design activities, engineering R&D was conducted covering all necessary issues, such as development of structural materials, tritium breeding materials, and neutron multiplier materials; neutronics experiments and analyses; and development of the blanket module fabrication technology. Upon developing the fabrication technology for the first wall and box structure, a hot isostatic pressing bonded F82H first wall mock-up with embedded rectangular cooling channels was

    A fast reactor (FR) cycle has a potential to realize a sustainable energy supply system that is harmonized with environment by fully recycling both uranium (U) and transuranium (TRU) elements. In Japan, a Feasibility Study on Commercialized FR Cycle Systems (FS) was launched in July 1999, and through two different study phases, a final report was presented in 2006. As a result of FS, a combined system of sodium-cooled FR with mixed-oxide (MOX) fuel, advanced aqueous reprocessing and simplified pelletizing fuel fabrication was considered to be most promising for commercialization. The advanced aqueous reprocessing system, which is called the New Extraction system for TRU recovery (NEXT), consists of a U crystallization process for the bulk of U recovery, a simplified solvent extraction process for residual U, plutonium (Pu) and neptunium (Np) without Pu partitioning and purification, and a process for recovering americium (Am) and curium (Cm) from the raffinate. The ratio of Pu/U concentration in the mother solution after crystallization is adequate for MOX fuel fabrication, and thus complicated powder mixing processes for adjusting Pu content in MOX fuel can be eliminated in the subsequent simplified fuel fabrication system. In this system, lubricant-mixing process can also be eliminated by adopting the advanced technology in which lubricant is coated on the inner surface of a die before fuel powder supply. Such a simplification could help us overcoming the difficulty to treat MA bearing fuel powders in a hot cell. Ministry of Education, Culture, Sports, Science and Technology (MEXT) reviewed these results of FS in 2006 and identified the most promising FR cycle concept proposed in the FS phase II study as a mainline choice for commercialization. According to such a governmental assessment, R and D activities of FR cycle systems were decided to be concentrated mainly to the innovative technology development for the mainline concept. The stage of R and D project was

    The Central Disaster Management Council of Japan estimates the next great M7+ earthquake in the Tokyo metropolitan region will cause 11,000 fatalities and 112 trillion yen (1 trillion US) economic loss at worst case if it occur beneath northern Tokyo bay with M7.3. However, the estimate is based on a source fault model by conventional studies about the PSP geometry. To evaluate seismic hazard due to the great quake we need to clarify the geometry of PSP and also the Pacific palate (PAP) that subducs beneath PSP. We identify those plates with use of seismic tomography and available deep seismic reflection profiling and borehole data in southern Kanto area. We deployed about 300 seismic stations in the greater Tokyo urban region under the Special Project for Earthquake Disaster Mitigation in Tokyo Metropolitan Area. We obtain clear P- and S- wave velocity (Vp and Vs) and Q tomograms which show a clear image of PSP and PAP. A depth to the top of PSP, 20 to 30 kilometer beneath northern part of Tokyo bay, is about 10 km shallower than previous estimates based on the distribution of seismicity (Ishida, 1992). This shallower plate geometry changes estimations of strong ground motion for seismic hazards analysis within the Tokyo region. Based on elastic wave velocities of rocks and minerals, we interpreted the tomographic images as petrologic images. Tomographic images revealed the presence of two stepwise velocity increase of the top layer of the subducting PSP slab. Rock velocity data reveals that subducting PSP crust transforms from blueschists to amphibolites at depth of 30km and amphibolites to eclogites at depth of 50km, which suggest that dehydration reactions occurs in subducting crust of basaltic compositions during prograde metamorphism and water is released from the subducting PSP crust. Tomograms show evidence for a low-velocity zone (LVZ) beneath the area just north of Tokyo bay. A Q tomogram show a low Q zone in PSP slab. We interpret the LVZ as a

    We report a case of severe leptospirosis that occurred during winter in Tokyo, the capital of Japan. Leptospirosis is endemic in tropical regions and extremely rare in the urban areas of Japan. Only six new cases were reported in Tokyo in 2014. Most leptospirosis cases reported in urban areas of Japan were a result of occupational hazards, and there is no previous report of leptospirosis in a homeless patient in Tokyo. We believe this report could provide a widened perspective about the clinical presentation and epidemiology of leptospirosis in Japan. Our patient was a 73-year-old Asian man. He had been homeless for over 10 years, with exposure to rodents and their excrement in parks and on the streets. He presented with fever and severe inflammatory response, satisfying the diagnostic criteria for systemic inflammatory response syndrome. Laboratory findings showed multiple-organ dysfunction, including renal failure, liver failure with increased total bilirubin level, and coagulopathy with decreased platelets. We suspected leptospirosis on the basis of these clinical findings. The diagnosis was also confirmed by polymerase chain reaction first, and paired antibody titers on day 9, in the recovery period, showed positive results for three species. Our patient's case suggests that even patients without a history of traveling abroad or exposure to freshwater can develop leptospirosis in winter in urban areas in Japan. If a patient has symptoms like fever, calf pain and MOF; as a differential diagnosis we should rule outthe Leptospirosis. From the perspective of sensitivity, specificity, and clinical convenience, polymerase chain reaction could be the preferred diagnostic tool of choice.

    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.

  1. Seismic Observation in Deep Boreholes and Its Applications - Workshop Proceedings, Niigata Institute of Technology, Kashiwazaki, Japan

    International Nuclear Information System (INIS)

    2014-01-01

    The Kashiwazaki WS was held to develop the recommendations made at the Tsukuba WS entitled 'Seismic Input Motions Incorporating Recent Geological Studies' which was held in November 2004 in Tsukuba City in Japan (hereinafter, the 'Tsukuba WS'). At the Tsukuba WS, the state of the art in defining realistic seismic input for the design and re-evaluation of nuclear facilities as well as advances in seismic source characterization of fault zones using data from deep geological investigations and their possible contribution to improving seismic input definitions were reviewed. Further, the importance and necessity of cooperation between seismology and geology in order to decrease uncertainty in seismic input definition were emphasized. After the Tsukuba WS, the Niigata-ken Chuetsu-oki Earthquake (NCOE, M=6.8) occurred near the Kashiwazaki-Kariwa NPP site. In this earthquake, a focusing effect of ground motion was observed at the Kashiwazaki-Kariwa NPP site, which caused locally amplified ground motion. Units 1 and 2 showed significantly higher responses of more than 50 percent compared to Units 3 to 7. This was thought to be caused by the fact that seismic waves were focused on Units 1 and 2 due to the irregular structure under the site. A similar effect was observed at the Hamaoka site in the earthquake that occurred in Suruga Bay in 2009. Only Unit 5 showed a double or larger response to this earthquake, and similar phenomena were found only for events with hypocenter in the narrow direction from the site. This was also thought to be caused by the irregular geological structure under the site. In the 2011 off the Pacific Coast of Tohoku Earthquake, the peak ground accelerations (PGA) of the Dai-ichi NPP site were about twice as large as those of the Dai-ni NPP site, although the distance between these sites is only slightly more than 10 km. Further, large differences in the PGAs were found among each of the units of the Dai-ichi NPP site. For example, the PGA of Unit

    Furumoto, A.S.

    1987-12-31

    This was an experiment to test whether cloth dyeing using geothermal steam (already proven in Japan) would be feasible in Hawaii. Results: Using a fabricated steam vat, cotton, silk, and synthetic can be dyed; the resulting material received high grades for steadfastness and permanency under dye testing. Techniques that were successful in Matsukawa, were replicated in Puna. However, attempts to embed leaf patterns on cloth using natural leaves and to extract natural dyes from Hawaiian plants were unsuccessful; the color of natural dyes deteriorated in hours. But chemical dyes gave brilliant hues or shades, in contrast to those in Japan where the steam there gave subdued tones. It is concluded that geothermal dyeing can be a viable cottage industry in Puna, Hawaii.

    A growing population and urbanization is a challenge for finite natural resources. Without strict regulation to recycle, recover and reuse resources, waste is discarded with no value. Every year throughout the world, more than twenty-five million vehicles turn into end-of-life vehicles (ELV) and most of their valuable resources end up in landfill sites. This research analyses the effect of regulation on ELV innovation for additional recovery of resources in Japan and EU nations using patent data as a proxy. The analysis determines the statistical difference in patent activity before and after regulations were enacted in the case studies. The relevant data on ELV technologies was gathered for the period 1985-2013. The study suggests that in general environmental regulation in Japan drove innovation and reveals that environmental policy in Japan was more effective in enabling innovation compared to EU nations. Specifically, the results from these developed countries can be used by the rapidly growing developing countries in automobile manufacturing like China for amendment of their ELV regulation accordingly.

    This research was conducted to reveal Japanese mothers' changing perceptions towards their technology-dependent children in the home care setting. Fourteen Japanese mothers participated in semi-structured interviews, which were analyzed using a grounded theory approach. "Degree of preoccupation with the child" emerged as the category representing the mothers' perceptions towards their child. Three categories emerged that represented the progression of maternal perceptions over time: "accepting the child's conditions", "mastering the management of care in various conditions", and "considering social participation for the child". First, mothers gradually accepted the conditions of their child after his/her disease and disability were known. Second, others managed technology-required care and concurrently considered the social participation of their child through daily care at home. Third, the level of preoccupation with the child was affected by the mothers' management of care and their attitude towards the social participation of their child in home care. In this study, as is widely alleged in historical recognition of Japan, mothers provided daily care almost without help from other family members. Additionally, they thought it natural and good for their children. Above all, especially in Japan, professional support for mothers are necessary so that they can take breaks from care.

    A high-purity Ar gas atmosphere glove box accommodating injection casting and sodium-bonding apparatuses was newly installed in the Plutonium Fuel Research Facility of Oarai Research and Development Center, Japan Atomic Energy Agency, in which several nitride and carbide fuel pins were fabricated for irradiation tests. The experiences led to the establishment of the technological basis of the fabrication of U-Pu-Zr alloy fuel pins for the first time in Japan. After the injection casting of the U-Pu-Zr alloy, the metallic fuel pins were fabricated by welding upper and lower end plugs with cladding tubes of ferritic-martensitic steel. Subsequent to the sodium bonding for filling the annular gap region between the U-Pu-Zr alloy and the cladding tube with the melted sodium, the fuel pins for irradiation tests are inspected. This paper shows the apparatuses and the technological basis for the fabrication of U-Pu-Zr alloy fuel pins for the irradiation test planned at the experimental fast test reactor Joyo. (author)

  9. A 35-40% Likelihood of a Highly Damaging Tokyo Earthquake in Next 30 Years

    2005-12-01

    Tokyo and its outlying cities are home to one-quarter of Japan's 127 million people. Highly destructive earthquakes struck the capital in 1703, 1855 and 1923, the last of which took 105,000 lives. Reoccurrence of any of these shocks today would cost about one trillion dollars, of which perhaps 10% is insured. Fueled by Tokyo's rich data trove but hindered by its complexity, we carried out a new hazard assessment. We used the prehistoric record of great earthquakes preserved in uplifted marine terraces and tsunami deposits (17 M~8 shocks in the past 7,000 years), historical shaking (10,000 intensity observations in the past 400 years), the dense modern seismic network (300,000 earthquakes in the past 30 years), and the world's best geodetic array (150 GPS vectors spanning the past 10 years). We propose that a dislodged block of the Pacific plate is jammed between the Pacific, Philippine Sea and Eurasian plates beneath Tokyo, and controls much of Tokyo's seismic behavior for M≤7.5 shocks, including the damaging 1855 M~7.3 Ansei-Edo shock. On the basis of frequency-magnitude curves, earthquakes similar to the Ansei-Edo event should be quite frequent (25-35% likelihood in an average 30-yr period), and so such events dominate the combined probabilities. In contrast, our renewal model for the great 1703 and 1923 type plate boundary shocks yields a ~1% probability for the next 30 yr, with a time-averaged 30-yr probability of ~8%. The resulting net likelihood for severe shaking in Tokyo, Kawasaki, and Yokohama for the next 30 years is 25%-40%, but how can it be validated? The long historical record in Kanto affords a rare opportunity to calculate the probability of shaking in an alternative manner, based almost exclusively on intensity observations. This approach permits robust estimates for the spatial distribution of shaking, even for sites with few observations. The resulting probability of severe shaking over an average 30-yr period is ~35% in the Tokyo, Kawasaki

    Full Text Available In this paper, an analysis is made of the technology and standardization strategies regarding ECHONET and KNX, which are the de jure standards for smart houses in Japan and Europe. Eleven interviews with the main actors related to the ECHONET Consortium and KNX were conducted. Three research questions were set. What are the technology strategy related concerns of the main actors related to ECHONET? What are the issues related to the diffusion of smart houses? What are the underlying strengths and weaknesses of ECHONET when compared with KNX? The analyses showed that the strategies of the various actors towards the diffusion of smart houses were different, based on their different perspectives, visions and competences. A comparison between Japanese and European case highlighted the different standardization strategies and areas of focus. The main bottlenecks towards the diffusion of smart houses were identified.

    The deployment of innovative technologies, which have the potentiality to make breakthroughs in the future but have been kept remained at early stages of development because of their uncertain technological values, is important in the course of introduction and dissemination of hydrogen energy into our society. In Japan, in the consecutive projects of 'World Energy Network' (WE-NET) and 'Development of Safe Utilization Technology and an Infrastructure for Hydrogen Use', both supported by New Energy and Industrial Technology Development Organization (NEDO), significant results have been achieved in the project of 'Research on Innovative Technologies'. The framework and characteristics of this project are outlined with several research topics. In the exploratory research on the alternative catalytic materials to Platinum group metals for fuel cells and hydrogen production, a series of Tantalum oxynitrides were found potentially applicable as new electrodes catalysts the development of magnetic refrigeration of hydrogen is under way with the finding of materials with feasible properties; in search of innovative hydrogen storage systems, a new process of decalin dehydrogenation / naphthalene hydrogenation based on superheated liquid-film-type catalysis was developed.

    This paper introduces recent space debris related activities in Japan. As for the ground based observation, the progress of the 1 m optical telescope construction at the Bisei Space Guard Center is to be reported as well as technology development such as the automated debris detection and attitude estimation techniques from optical image data. Next, activities on the hypervelocity acceleration technology are to be mentioned. Tokyo Institute of Technology team succeeded to launch a projectile of 0.6 g at 8.2 km/s using their Two-/Three- Stage Light Gas Gun, which is believed to be the world record for TSLGGs. In addition, National Aerospace Laboratory has been continuing their efforts to develop the Inhibited Conical Shaped Charge Launcher and is currently investigating the effects of high internal energy and irregular shape of the projectile. Based on the projectile density measurement method newly proposed by them, comparison with the other CSC system than NAL's one is to be shown. Finally, introduced is the progress of research activities on the active removal system for post mission spacecraft. Based on the technological foundation acquired in the ETS-VII experiment, NAL and NASDA are pursuing the possibility of active removal of system level large objects from the densely populated orbit, which contains a lot of technological challenges such as angular motion estimation using only image data, angular momentum dissipation, electro-dynamic tether as a highly efficient thruster and remote and autonomous robot operation. Also shortly introduced is domestic dis cussion on implementation of debris related activities in Japan's new space development organization to be founded in January 2004.

    The abuse of "Kiken drugs," including synthetic cannabinoids, is a serious and growing social problem in Japan. Kiken drugs is the general term for novel psychoactive substances that have not been designated as illegal by Japanese law. The aim of this article is to describe the current status of the abuse of Kiken drugs by youth in the nightlife areas of Tokyo. An anonymous field-based survey was conducted using laptop computers at four dance parties in Tokyo, Japan. The questionnaires were completed by 307(44% female, mean age 30.9 years) young adults at the dance parties. Among the survey participants, 24.4% reported Kiken drug use (herbs 22.8%, powders 7.2%, and liquids 3.3%) in their lifetime. The primary reasons for Kiken drug use were peer pressure (37.3%), and avoiding penalties for possession of illegal drugs under Japanese laws (28.0%). In addition, 61.3% reported obtaining Kiken drugs from close friends. Our results clearly suggest that young adults at dance parties have a higher lifetime prevalence of Kiken drug use than the Japanese general population (0.4% reported in 2013). As the social stigma associated with drug use is extremely high in Japan, avoiding illegal drugs prohibited by law by using easily available Kiken drugs may be more socially acceptable among youth in the nightlife areas.

    Japan got hit in 1992, and it got hit bad. After a long period of higher growth than the U.S. and Europe, recession caught up with Japan's economy, and it has stagnated in 1992. And for Japan's $183-billion/year chemicals industry the impact has been sudden. Japan Chemical Industry Association (JCIA: Tokyo) says that on a yen basis, the sector's 1992 sales will probably be 5% lower than in 1991. Between 1990 and 1991, the industry chalked up 12% growth. Furthermore, recession outside Japan is magnifying Japanese petrochemical and polymer producers troubles, even though only 10% of output is sold in export markets

    Japanese basic policy regarding disposal of high-level radioactive waste (HLW) is to solidify it into stabilized form, to store it for 30-50 years to be cooled, and to dispose of it deep to the underground (geological disposal). In Japan, reference to P and T technology for long-lived and other nuclides first appeared in the Long-term Programme for Nuclear Research, Development and Utilisation (or 'long-term nuclear programme') back in 1972. That programme noted the need for research and development in order to ensure effective processing of radioactive waste. The long-term nuclear programme issued in 1987 stated that P and T technology was very important from the viewpoint of recycling HLW and enhancing disposal efficiency. It also stated that systematic R and D would be carried out jointly by JAERI, the Power Reactor and Nuclear Fuel Development Corp. (PNC, now JNC) and others. The long-term nuclear programme issued in 1994 stated that each research institute would carry out basic studies on P and T technologies and evaluate each technology at some time in the mid- 1990's to determine how to proceed thereafter. Based on the evaluation schedule stated in this program, the AEC's Advisory Committee on Nuclear Fuel Cycle Back-end Policy investigated and considered matters concerning P and T technology for long-lived and other nuclides. In March 2000, the Committee issued a report entitled 'Research and Development of Technologies for Partitioning and Transmutation of Long-lived Nuclide Status and Evaluation Report'. A brief summary of this report is presented

    In 1970s, the material patent system was introduced in Japan. Since then, many Japanese pharmaceutical companies have endeavored to create original in-house products. From 1980s, many of the innovative products were small molecular drugs and were developed using powerful medicinal-chemical technologies. Among them were antibiotics and effective remedies for the digestive organs and circulatory organs. During this period, Japanese companies were able to launch some blockbuster drugs. At the same time, the pharmaceutical market, which had grown rapidly for two decades, was beginning to level off. From the late 1990s, drug development was slowing down due to the lack of expertise in biotechnology such as genetic engineering. In response to the circumstances, the research and development on biotechnology-based drugs such as antibody drugs have become more dynamic and popular at companies than small molecule drugs. In this paper, the writers reviewed in detail the transitions in drug discovery and development between 1980 and 2010.

    Laser flare photometry (LFP) is an objective and quantitative method to measure intraocular inflammation. The LFP technology was developed in Japan and has been commercially available since 1990. The aim of this work was to review the application of LFP in uveitis practice in Europe compared to Japan where the technology was born. We reviewed PubMed articles published on LFP and uveitis. Although LFP has been largely integrated in routine uveitis practice in Europe, it has been comparatively neglected in Japan and still has not received FDA approval in the USA. As LFP is the only method that provides a precise measure of intraocular inflammation, it should be used as a gold standard in uveitis centres worldwide.

    Research and development on advanced high heat flux cooling technology for electronic devices has been carried out as the Project of Fundamental Technology Development for Energy Conservation, promoted by the New Energy and Industrial Technology Development Organization of Japan (NEDO). Based on the microgravity experiments on boiling heat transfer, the following useful results have obtained for the cooling of electronic devices. In subcooled flow boiling in a small channel, heat flux increases considerably more than the ordinary critical heat flux with microbubble emission in transition boiling, and dry out of the heating surface is disturbed. Successful enhancement of heat transfer is achieved by a capillary effect from grooved surface dual subchannels on the liquid supply. The critical heat flux increases 30-40 percent more than for ordinary subchannels. A self-wetting mechanism has been proposed, following investigation of bubble behavior in pool boiling of binary mixtures under microgravity. Ideas and a new concept have been proposed for the design of future cooling system in power electronics.

    The study was conducted with the intention of establishing a strategy to eliminate measles on the basis of an analysis of the epidemiological profile of measles cases reported in Tokyo during the year 2011. We investigated measles cases reported to the Tokyo Metropolitan Government in 2011, recorded as part of the National Epidemiological Surveillance of Infectious Diseases. Factors analyzed included age, vaccination status for each patient, cases for which records were discarded after laboratory confirmation, genotype of the measles virus and relationships between dates of specimen collection and results of polymerase chain reaction (PCR) and IgM antibody tests. A total of 178 measles cases were reported in Tokyo during 2011, and the majority of cases (128, 71.9%) were reported during the peak period from epiweeks 13 to 24. The largest age group reported was one to four years of age (40, 22.5%) followed by groups of 20-29 and 30-39 years of age (both 34, 19.1%). Most cases were sporadic, with only six outbreaks occurring. Even then, the numbers of cases for each outbreak was less than five. More than half of the patients in all age groups, except for the 1-4-year-old group, had not been vaccinated or did not have a record of vaccination. Genotypes D4 and D9 of measles virus were detected in most cases. However, genotype D5, which had been circulating in Japan before 2008, was not detected. Imported viruses were the cause of measles cases reported in Tokyo during 2011. The disease control was better than that in 2007 and 2008 because of the swift and appropriate responses to the occurrences. It is also possible that there has been an increase in the proportion of people with immunity to measles. Increasing the rate of immunization, performing effective surveillance, and confirming suspicious measles cases by using molecular methods are important for achieving the elimination of measles.

    Nanotechnologies are often said to be "converging" with other technologies like biotechnology, information technology, and cognitive science. And so-called "NBIC convergence" is thought to enable "enhancement" of human performance. First, I classify various kinds of enhancement. Second, I focus on the "cybernetic enhancement," to which nanotechnologies are supposed to contribute, and analyze the connection and integration of humans with machines, which could lead to the cyborgization of human beings. Third, I examine the portrayal of robot/cyborg technology in Japanese popular media, point out the tendency to empathy or ensoulment concerning robots/cyborgs, and raise the question of "ethical issues of ethical enhancement." Fourth, I compare nanotechnologies with neurotechnology and criticize the hype of "converging technologies."

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

    This perspective piece gives an overview of the current situation of yoga therapy in Japan today. Traditional yoga in Japan suffered a serious setback in 1995 with a nerve gas terrorist attack on the Tokyo subway, which was carried out by a cult that recruited members through yoga classes. But with the increase in popularity with modern forms of yoga such as Iyengar yoga, Ashtanga yoga and hot yoga in the West, the general public in Japan today is forgetting its aversion to yoga and considers it to be something that can contribute to good health. In 2012, the Japan Yoga Therapy Society (JYTS) conducted a study on adverse events in yoga classes throughout Japan with the University of Kyushu School of Medicine, with support from the Ministry of Health, Labour and Welfare. This study indicated that more than half of people attending yoga classes have some form of chronic illness, with 42.3% receiving outpatient care. This survey was the beginning of growing interest from both the government and universities in yoga therapy. JYTS is beginning to make inroads into bringing yoga therapy into cancer and palliative care, senior citizen homes, alcohol and drug addiction rehabilitation, cardiovascular rehabilitation, and research on trauma and schizophrenia. While there are still limited opportunities for yoga therapists to work in mainstream healthcare services, there is growing interest among medical professionals in both physical and mental health.

    For the upcoming 2020 Olympic Games, which are to be held in Tokyo, Japan, it has been proposed that recycled metal from electronic waste should be used to create the gold, silver, and bronze medals that will be awarded to athletes from around the world. This work is aimed at exploring the feasibility of this goal, quantifying the required electronic waste, identifying the limiting material constraints, and addressing a selection of sustainability metrics. The results show that 2.5-13.8% of Japan's available electronic waste would be required to create the medals, depending on the composition of the collected electronics and the processing yields. The environmental benefits from this venture are identified as being a savings of approximately 4.5-5.1 TJ of energy, which is equivalent to CO2 emissions reductions of approximately 420 metric tons. Additionally, qualitative potential benefits to environment, human health, economic recovery of valuable materials, and supply stability are considered.

    The Tokyo subway sarin attack was the second documented incident of nerve gas poisoning in Japan. The authors report how St. Luke's Hospital dealt with this disaster from the viewpoint of disaster management. Recommendations derived from the experience include the following: Each hospital in Japan should prepare an emergent decontamination area and have available chemical-resistant suits and masks. Ventilation in the ED and main treatment areas should be well planned at the time a hospital is designed. Hospital disaster planning must include guidance in mass casualties, an emergency staff call-up system, and an efficient emergency medical chart system. Hospitals should establish an information network during routine practice so that it can be called upon at the time of a disaster. The long-term effects of sarin should be monitored, with such investigation ideally organized and integrated by the Japanese government.

    Full Text Available Japan currently has been successful to provide housing for low to high-income people in urban areas. Almost everyone in Japan can access their homes, either public housing or private one, depending on the level of their welfare status. The study discusses about development of public housing in Japan and why the Japanese people can accept the design of the vertical housing built by their government. The study is conducted with descriptive approach through literature study and field observations in the city of Tokyo and its surrounding areas to provide knowledge about the development of public housing in Japan started from traditional residential and then developed into a modern residential horizontally and vertically according to the needs of his hometown community. Despite of the development from time to time, the design of residence still considers the local culture of Japan. So the Japanese people can receive residential design, although it is developed into vertical housing. This study is expected to give inputs for the Indonesian government as an effort to achieve the successful provision of public housing in Indonesia.

    Older mothers are becoming more common in Japan. One reason for this is the widespread use of assisted reproductive technology (ART). This study assesses the relationship between maternal age and the risk of birth defects after ART. Nationwide data on ART between 2004 and 2010 in Japan were analyzed. Diseases that were classified as code Q00-Q99 (ie, congenital malformations, deformations, and chromosomal abnormalities) in the International Classification of Diseases, tenth edition, were selected. There were 219,185 pregnancies and 153,791 live births in total ART. Of these, 1943 abortions, stillbirths, or live births with birth defects were recorded. Percentage of multiple birth defects in total birth defects, the prevalence, crude relative risk and 95% confidence interval per 10,000 pregnancies and per 10,000 live births were analyzed according to the maternal age class (ie, 25-29, 30-34 (reference), 35-39, and 40+ years). Multiple birth defects were observed among 14% of the 25-29 year old class, and 8% among other classes when chromosomal abnormalities were excluded. The prevalence of chromosomal abnormalities per pregnancy and per live birth became significantly and rapidly higher in mothers in the age classes of 30-35 and 40+ years. Nonchromosomal birth defects per pregnancy decreased linearly with advanced maternal age, while the number of nonchromosomal birth defects per live birth formed a gradual U-shaped distribution. The prevalence per pregnancy of congenital malformations of the nervous system was significantly lower with advanced maternal age. The relative risk per live birth was significant regarding congenital malformations of the circulatory system for a maternal age of 40+ years. Some other significant associations between maternal age and birth defects were observed. Maternal age is associated with several birth defects; however, older maternal age in itself does not produce noticeable extra risk for nonchromosomal birth defects overall.

    Optical coherence tomography (OCT) angiography (OCTA) is a novel, noninvasive, three-dimensional imaging technique that allows for the visualization of intravascular flow in the microvasculature. Swept-source OCT technology utilizes longer-wavelength infrared light than conventional spectral-domain OCT. This enables improved penetration into tissue and imaging through optical opacities and is invisible to the subject. Topcon has recently developed an innovative OCTA algorithm, OCTARA (OCTA Ratio Analysis), which benefits from being paired with swept-source OCT. OCTARA aims to provide improved detection sensitivity of low blood flow and reduced motion artifacts without compromising axial resolution. In this chapter, we describe the implementation of OCTARA with swept-source OCT technology, the technical specifications of acquisition (e.g. the number of scans, area of examination field, etc.) along with the algorithm's function and principles for analysis of B-scan data to achieve angiographic visualization. Examples of OCTA scans performed using the OCTARA algorithm and a comparison of these scans with images obtained using other technologies are also presented. © 2016 S. Karger AG, Basel.

    The aim of this study was to assess the efficacy of assisted hatching (AH) in assisted reproductive technology (ART) treatment. In this retrospective observational study, the data of patients who were registered in the National ART Registry System of Japan between January and December 2010 were analyzed. The descriptive statistics and validity of AH in fresh embryo transfer (ET) and frozen-thawed ET were assessed by using multiple logistic regression analyses. From a total of 105,450 single ET, 46,029 (43.7%) cycles underwent AH. A total of 9737 (21.3%) and 36,292 (60.9%) cycles underwent AH from 45,818 fresh single ET and 59,632 frozen-thawed single ET, respectively. In the fresh ET patients that underwent AH, the clinical pregnancy and live birth rate were significantly decreased in patients of all ages compared with that of the non-AH group. In the frozen-thawed ET patients, there was no significant difference in pregnancy and live birth rate between the AH group and the non-AH group. AH treatment was more frequently performed in frozen-thawed ET patients than in fresh ET patients, and in the blastocyst stage than in the early cleavage stage. A significantly decreased pregnancy and live birth rate was observed in the fresh ET patients who underwent AH. In the frozen-thawed ET patients who underwent AH, improvement in the clinical pregnancy and live birth rate was not observed. Further studies on the indication and application of AH in ART treatment are required. © 2014 The Authors.

    2006-01-01

    The high-temperature gas-cooled reactor (HTGR), which is graphite-moderated and helium-cooled, is attractive due to its unique capability of producing high temperature helium gas and its fully inherent reactor safety. In particular, hydrogen production using the nuclear heat from HTGR (up to 900 deg. C) offers one of the most promising technological solutions to curb the rising level of CO 2 emission and resulting risk of climate change. The interests in HTGR as an advanced nuclear power source for the next generation reactor, therefore, continue to rise. This is represented by the Japanese HTTR (High-Temperature Engineering Test Reactor) Project and the Chinese HTR-10 Project, followed by the international Generation IV development program, US nuclear hydrogen initiative program, EU innovative HTR technology development program, etc. To enhance nuclear energy application to heat process industries, the Japan Atomic Energy Agency (JAEA) has continued extensive efforts for development of hydrogen production system using the nuclear heat from HTGR in the framework of the HTTR Project. The HTTR Project has the objectives of establishing both HTGR technology and heat utilization technology. Using the HTTR constructed at the Oarai Research and Development Center of JAEA, reactor performance and safety demonstration tests have been conducted as planned. The reactor outlet temperature of 950 deg. C was successfully achieved in April 2004. For hydrogen production as heat utilization technology, R and D on thermo-chemical water splitting by the 'Iodine-Sulfur process' (IS process) has been conducted step by step. Proof of the basic IS process was made in 1997 on a lab-scale of hydrogen production of 1 L/h. In 2004, one-week continuous operation of the IS process was successfully demonstrated using a bench-scale apparatus with hydrogen production rate of 31 L/h. Further test using a pilot scale facility with greater hydrogen production rate of 10 - 30 m 3 /h is planned as

  7. A NEW HEALTH TECHNOLOGY ASSESSMENT SYSTEM FOR JAPAN? SIMULATING THE POTENTIAL IMPACT ON THE PRICE OF SIMEPREVIR.

    Science.gov (United States)

    Mahlich, Jörg; Kamae, Isao; Rossi, Bruno

    2017-01-01

    Japanese authorities have announced a plan to introduce a health technology assessment (HTA) system in 2016. This study assessed the potential impact of such a policy on the price of the antivirologic drug simeprevir. Taking the antivirologic drug simeprevir as an example, we compared the current Japanese price with hypothetical prices that might result if a U.K. (cost-utility) or German (efficiency frontier) style HTA assessment was in place. The simeprevir unit price under the current Japanese pricing scheme is 13,122 Japanese yen (equivalent to 109.35 U.S. dollars as of April 2015). Depending on the selection of comparators and the pricing method, and assuming that HTA will be used as a basis for price setting, the estimated prices of simeprevir vary up to four times higher than under the current Japanese pricing scheme. Although the analysis is based on only one drug, it cannot be taken for granted that a new HTA system would reduce public healthcare expenditure in Japan.

  8. Corroborating a new probabilistic seismic hazard assessment for greater Tokyo from historical intensity observations

    Bozkurt, S.; Stein, R.; Toda, S.

    2006-12-01

    The long recorded history of earthquakes in Japan affords an opportunity to forecast seismic shaking exclusively from past observations of shaking. For this we analyzed 10,000 intensity observations recorded during AD 1600-2000 in a 350 x 350 km area centered on Tokyo in a Geographic Information System. A frequency-intensity curve is found for each 5 x 5 km cell, and from this the probability of exceeding any intensity level can be estimated. The principal benefits of this approach is that it builds the fewest possible assumptions into a probabilistic seismic forecast, it includes site and source effects without imposing this behavior, and we do not need to know the size or location of any earthquake or the location and slip rate of any fault. The cost is that we must abandon any attempt to make a time-dependent forecast, which could be quite different. We believe the method is suitable to many applications of probabilistic seismic hazard assessment, and to other regions. The two key assumptions are that the slope of the observed frequency-intensity relation at every site is the same, and that the 400-year record is long enough to encompass the full range of seismic behavior. Tests we conduct suggest that both assumptions are sound. The resulting 30-year probability of IJMA>=6 shaking (roughly equivalent to PGA>=0.9 g or MMI=IX-X) is 30-40% in Tokyo, Kawasaki, and Yokohama, and 10-15% in Chiba and Tsukuba, the range reflecting spatial variability and curve-fitting alternatives. The strongest shaking is forecast along the margins of Tokyo Bay, within the river sediments extending northwest from Tokyo, and at coastal sites near the plate boundary faults. We also produce long- term exceedance maps of peak ground acceleration for building code regulations, and short-term hazard maps associated with hypothetical catastrophe bonds. Our results for greater Tokyo resemble our independent Poisson probability developed from conventional seismic hazard analysis, as well as

  9. Japan's anti-nuclear weapons policy misses its target, even in the war on terrorism.

    DiFilippo, Anthony

    2003-01-01

    While actively working to promote the abolition of all nuclear weapons from the world since the end of the cold war, Japan's disarmament policies are not without problems. Promoting the elimination of nuclear weapons as Japan remains under the US nuclear umbrella creates a major credibility problem for Tokyo, since this decision maintains a Japanese deterrence policy at the same time that officials push for disarmament. Tokyo also advocates a gradual approach to the abolition of nuclear weapons, a decision that has had no effect on those countries that have been conducting sub-critical nuclear testing, nor stopped India and Pakistan from carrying out nuclear tests. Consistent with Article 9 of the Constitution, the Japanese war-renouncing constitutional clause, Tokyo toughened Japan's sizeable Official Development Assistance (ODA) programme in the early 1990s. Because of the anti-military guidelines included in Japan's ODA programme, Tokyo stopped new grant and loan aid to India and Pakistan in 1998 after these countries conducted nuclear tests. However, because of the criticism Japan faced from its failure to participate in the 1991 Gulf War, Tokyo has been seeking a new Japanese role in international security during the post-cold war period. Deepening its commitment to the security alliance with the US, Tokyo has become increasingly influenced by Washington's global polices, including the American war on terrorism. After Washington decided that Pakistan would be a key player in the US war on terrorism, Tokyo restored grant and loan aid to both Islamabad and New Delhi, despite the unequivocal restrictions of Japan's ODA programme.

    Although several studies have shown the relation between temperature/atmospheric pressure and pulmonary embolism (PE), their results are inconsistent. Furthermore, diurnal temperature range (DTR) and diurnal pressure range (DPR) were not fully evaluated for their associations with hospital admissions for PE. Study subjects comprised cases of 1,148 PE treated at institutions belonging to the Tokyo Cardiovascular Care Unit Network from January 2005 to December 2012. Patient data were combined with a variety of daily local climate parameters obtained from the Japan Meteorological Agency. Every 1°C increase in the DTR at lag0 corresponded to an increased relative risk of hospital admission for PE (odds ratio [OR] 1.036, 95% confidence interval [CI] 1.003 to 1.070). In the cooler season (November to April), an increase of 1 hPa (barometric pressure) in the DPR at lag4 and lag5 was associated with an increased relative risk of hospital admission for PE (OR 1.042, 95% CI 1.007 to 1.077 and OR 0.952, 95% CI 0.914 to 0.992, respectively). An increase in the PE hospitalization rate was seen only in the cool season. Using a metropolitan database, we showed that DTR and DPR have different impacts on hospital admissions for PE. In conclusion, we found that an increase in the DTR increases the PE hospitalization rate, especially during the cooler season. The impact of DTR and DPR on PE incidence and related hospitalizations needs to be further evaluated. Copyright © 2015 Elsevier Inc. All rights reserved.

    The purpose of the present study was to analyze birth defects (congenital anomalies) after assisted reproductive technology (ART) according to the method of treatment, namely in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI) and frozen-thawed embryo transfer (FET). Individual lists of all ART pregnancies resulting in birth defects from birth year 2004 to 2012 presented in the annual reports by the Japan Society of Obstetrics and Gynecology were used as the initial sources of information. Relative risks (RRs) with the corresponding 95 % confidence intervals (CIs) were calculated with IVF as the reference group when calculating RR of ICSI for IVF, and with FET as the reference group when calculating the RR of fresh embryo transfer for FET. In total, 2725 stillbirths or live births with birth defects were analyzed. The prevalence of birth defects was slightly yet significantly higher in ICSI compared with IVF throughout the study period (RR = 1.15, 95 % CI 1.02-1.29) and in the 2004-2006 period (RR = 1.26, 95 % CI 1.00-1.58). The prevalence of birth defects was significantly higher for fresh embryo transfer compared with FET in the 2004-2006 period (RR = 1.39, 95 % CI 1.12-1.72). The prevalence of birth defects in multiple births was significantly lower in fresh embryo transfer compared with FET (RR = 0.70, 95 % CI 0.55-0.90, live births of 2007-2012). The present descriptive epidemiological study suggests that the impacts of different ART methods on birth defects might differ.

  2. Forecasting probabilistic seismic shaking for greater Tokyo from 400 years of intensity observations (Invited)

    The long recorded history of earthquakes in Japan affords an opportunity to forecast seismic shaking exclusively from past shaking. We calculate the time-averaged (Poisson) probability of severe shaking by using more than 10,000 intensity observations recorded since AD 1600 in a 350-km-wide box centered on Tokyo. Unlike other hazard assessment methods, source and site effects are included without modeling, and we do not need to know the size or location of any earthquake or the location and slip rate of any fault. The two key assumptions are that the slope of the observed frequency-intensity relation at every site is the same; and that the 400-year record is long enough to encompass the full range of seismic behavior. Tests we conduct here suggest that both assumptions are sound. The resulting 30-year probability of IJMA≥6 shaking (~PGA≥0.9 g or MMI≥IX) is 30-40% in Tokyo, Kawasaki, and Yokohama, and 10-15% in Chiba and Tsukuba. This result means that there is a 30% chance that 4 million people would be subjected to IJMA≥6 shaking during an average 30-year period. We also produce exceedance maps of peak ground acceleration for building code regulations, and calculate short-term hazard associated with a hypothetical catastrophe bond. Our results resemble an independent assessment developed from conventional seismic hazard analysis for greater Tokyo. Over 10000 intensity observations stored and analyzed using geostatistical tools of GIS. Distribution of historical data is shown on this figure.

    On March 11, 2011, the Great East Japan Earthquake devastated the Tohoku region, which led to a tsunami and a nuclear disaster. While these three disasters caused tremendous physical damage, their psychological impact remains unclear. The present study evaluated traumatic responses, internalizing (i.e., anxiety and depression), and externalizing (i.e., anger) symptoms among Japanese young people in the immediate aftermath and 2.5 years later. A total of 435 undergraduates were recruited from universities in three differentially exposed regions: Fukushima, Tokyo, and Kyoto. They completed a set of questionnaires retrospectively (i.e., September to December 2013) to measure their traumatic responses, anxiety and depressive symptoms, functional impairment, and anger immediately after the disaster and 2.5 years later. Participants in Tokyo had the highest level of traumatic response and internalizing symptoms immediately after the earthquake, whereas those in Fukushima had significantly higher levels of trait anger, anger-in (holding one's anger in), and anger-out (expressing one's anger externally). In Kyoto, the levels of anxiety and depression after 2.5 years were significantly higher than they were immediately after the disasters. In conclusion, anger symptoms were high among young people who lived at or near the center of the disasters, while anxiety and depression were high among those who lived far away from the disasters. These findings suggest the importance of providing mental health services to young people who did not live near the disaster area as well as to those living in the directly affected area.

  6. Impact of energy consumption on urban warming and air pollution in Tokyo metropolitan area

    1995-01-01

    The rapid progress of industrialization and urbanization due to economic growth and concentration of social function in the urban areas in Japan have had an adverse effect on the urban environment. In most cities, it has become evident that the increase in energy consumption is causing environmental problems, including a temperature rise in the urban atmosphere (urban heat island) and air pollution. This paper reports the results of field observations and three dimensional simulations of the urban heat island using a three-dimensional modelling vorticity-velocity vector potential formation, in the Tokyo metropolitan area. According to the simulation for urban warming in the study area for the year 2031, the maximum temperature of a summer evening (18:00) would exceed 43 degrees celsius, indicating that Tokyo would no longer be comfortable for its inhabitants. It is concluded that in the near future, the problem of the urban heat island will become a more important issue than that of global warming because the rate of urban warming is greater. For this reason, the urban heat island could be fatal to humans unless resolved in the near future. (author). 1 tab., 11 figs., 18 refs

    1992-08-01

    Homeless problems associated with poverty may be considered almost resolved in Japan because of the post World War II economic development, but in large cities such as Tokyo the homeless are still being produced, a reflection of a variety of social problems. This study is based on an analysis of admission records of an institution for the homeless which was established in 1952 in Tokyo. Subjects are 2,122 single persons who were admitted between 1952 and 1985. Among these, 136 are mentally ill persons, who are the main subjects of analysis in this study. Results show that, which after 1970 the number of the mentally ill significantly increased, many of those people dropped out of the institution mostly because they were originally admitted directly from discharge from hospitals because there was no other place to go except the institutions, and also because the institution, originally meant to house street people who had been detained, did not offer appropriate programs for the mentally ill. A solution to these problems requires that roles of institutions for the homeless and subjects admitted be reconsidered. Institution staff should enrich programs designed for the homeless mentally ill and help them organize their social network and live in the community.

    The Tokyo subway sarin attack was the second documented incident of nerve gas poisoning in Japan. Prior to the Tokyo subway sarin attack, there had never been such a large-scale disaster caused by nerve gas in peacetime history. This article provides details related to how the community emergency medical services (EMS) system responded from the viewpoint of disaster management, the problems encountered, and how they were addressed. The authors' assessment was that if EMTs, under Japanese law, had been allowed to maintain an airway with an endotracheal tube or use a laryngeal mask airway without physician oversight, more patients might have been saved during this chemical exposure disaster. Given current legal restrictions, advanced airway control at the scene will require that doctors become more actively involved in out-of-hospital treatment. Other recommendations are: 1) that integration and cooperation of concerned organizations be established through disaster drills; 2) that poison information centers act as regional mediators of all toxicologic information; 3) that a real-time, multidirectional communication system be established; 4) that multiple channels of communication be available for disaster care; 5) that public organizations have access to mobile decontamination facilities; and 6) that respiratory protection and chemical-resistant suits with gloves and boots be available for out-of-hospital providers during chemical disasters.

    Fukushima Daiichi nuclear power plant accident (Fukushima accident) has brought about a great change in many people's perceptions about nuclear power plant safety. When discussing future energy options for Japan, it is important to have a full grasp of the attitude of a large number of people towards nuclear energy. The Atomic Energy Society of Japan has conducted annual questionnaire survey of 500 adults who live within 30 kilometers of Tokyo Station. The aim of this survey is to assess trends in public attitude towards nuclear energy. The authors that designed the questionnaire entries of this survey have been managing questionnaire data as members of the Data Management Working Group under the Social and Environmental Division of the Atomic Energy Society of Japan. We confirmed the change in public attitude towards nuclear energy through this periodical survey after the Fukushima accident. In particular, public concerns about the use of nuclear energy increased after the Fukushima accident, and many people have raised doubts over the use of nuclear energy in the future. (author)

    In order to assess the ecological risk posed by dioxins in the environment, information regarding the distribution of dioxin concentration under long term monitoring and over a wide area is necessary. However, it is almost impossible to obtain such data because dioxin analysis needs considerable time and effort. Thus, mathematical models that can predict dioxin concentrations in the environment are required. Especially in Japan, where main pathway of human exposure to dioxins is through consumption of fish and shellfish, investigation of aquatic environment is very important. However, data on these environmental mediums, such as river, bay, and inner sea, are very limited. In this study, a 3-D chemical fate prediction model was developed and applied to the Tokyo Bay estuary to predict distributions and variations of polychlorinated dibenzop- dioxins, dibenzofurans (PCDD/Fs), and dioxin-like PCBs in the seawater of the estuary.

    Nuclear Technology and Education Center was founded in 1958 and now has two branches, Tokyo Education Center at Bunkyo-ku, Tokyo and Tokai Education Center at Tokai, Ibaraki-ken. The objective was to educate and train nuclear engineers and scientists for implementing the nation's program of atomic energy research, development and utilization. A variety of training courses have been prepared and carried out to meet the requirements of the nuclear community. In recent years, activities of getting the public acceptance have become important for nuclear energy deployment in Japan. Many short courses have been implemented at JAERI sites and cities for providing the public including high school teachers with basic knowledge on nuclear energy. International training programs of the center were started with the cooperation of the Japan International Cooperation Agency (JICA) in 1985 and of the International Atomic Energy Agency (IAEA) in 1987. International seminars were implemented for improving nuclear safety by inviting participants from the former Soviet Union, central/east European countries and the neighboring countries of Japan under the direction of the Science and Technology Agency (STA) in 1992. STA and JAERI are starting new programs of helping Asian and Pacific countries to develop nuclear manpower. (author)

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

    The Olympic Games will be held in Tokyo in 2020 and the period will be the hottest period of the year in Japan. Marathon is a sport with a large heat load, and it is said that the risk of heat stroke rises more than other sports activities. The thermal environment of the 2020 Tokyo Olympic marathon course is analyzed by using wet-bulb globe temperature (WBGT) and Universal Thermal Climate Index (UTCI) map of the center area of Tokyo. The change due to the place, the effect of the shadow of the building, and the position on the course was analyzed from the distribution of WBGT and UTCI in the short-term analysis of sunny day from August 2 to August 6, 2014. To make the distribution map, we calculated distributions of sky view factor and mean radiant temperature of the 10 km × 7.5 km analyzed area in the center of Tokyo. Distributions of air temperature and humidity are calculated from Metropolitan Environmental Temperature and Rainfall Observation System data, which is a high-resolution measurement network. It was possible to incorporate the local variation of temperature and humidity of the analyzed area. In the result, the WBGT is about 1 °C lower and the UTCI is about 4-8 °C lower in the shadow of buildings from 9:00 to 10:00 than in the sunny side. As a cooling method, making a shadow is a relatively effective method. The variation along the course considering the distribution of meteorological data within the area is about 0.5 °C WBGT and 1 °C UTCI range. If we allow the error of this range, one-point meteorological data can be applied for the estimation along the course. Passing the right side (left side in the case of return) of the course could keep the accumulated value slightly lower along the course in the morning because the marathon course roughly runs from west to east and buildings' shadow is on the relatively right side (south side). But practically, the effect of changing the position on the course was small. The long-term analysis on

    The authors have collaborated for over three years in developing an advanced educational program to cultivate leading engineers who can productively interact with other stakeholders. The program is organized under a partnership between the Nuclear Engineering Department of University of California, Berkeley (UCBNE) and the Global COE Program 'Nuclear Education and Research Initiative' (GoNERI) of the University of Tokyo, and is funded by MEXT (Ministry of Education, Culture, Sports, Science and Technology), Japan. We conducted two 'summer schools' in 2009 and 2010 as trial cases of the educational program. This year, in response to the Fukushima Daiichi nuclear accident, we decided to make our third summer school a venue for preliminary, yet multi-dimensional learning from that event. This school was held in Berkeley, CA, in the first week of August, with 12 lecturers and 18 students from various fields and countries. In this paper, we will explain the concept, aim, and design of our program; do a preliminary assessment of its effectiveness; introduce a couple of intriguing discussions held by participants; and discuss the program's implications for the post-Fukushima nuclear context.

    The Advanced Boiling Reactor (ABWR) has been developed with international cooperation between Japan and the US as the generation of plants for the 1990s and beyond. It incorporates the best BWR technologies from the world in challengeable pursuit of improved safety and reliability, reduced construction and operating cost, reduced radiation exposure and radioactive waste. Tokyo Electric Power Company (MPCO) decided to apply the first ABWRs to unit No. 6 and 7 of Kashiwazaki-Kariwa nuclear power station (K-6 and 7). These units are scheduled to commence commercial operation in December 1996 and July 1997 respectively. Particular attention is given in this discussion to the construction period from rock inspection for the reactor building to commercial operation, which is to be achieved in only 52 months through innovative and challenging construction methods. To date, construction work is advancing ahead of the original schedule. This paper describes not only how to shorten the construction period by adoption of a variety of new technologies, such as all-weather construction method and large block module construction method, but also how to check and test the state of the art technologies during manufacturing and installation of new equipment for K-6 and 7

    Assisted reproductive technology (ART) such as in vitro fertilization (IVF) and embryo transfer (ET) has been essential in the treatment of infertility. The world's first IVF-ET baby was born in 1978 based on the technique developed by Dr. Robert Edwards and Dr. Patrick Steptoe. In Japan, the first IVF-ET birth was reported in 1983 by Prof. Masakuni Suzuki at Tohoku University School of Medicine. IVF-ET is a procedure used to achieve pregnancy that consists of extracting oocytes from an infertile woman, fertilizing them in vitro, and transferring fertilized eggs into the patient's uterine cavity (Fig. 1). Since the first report of successful IVF-ET, numerous techniques related to ART, such as cryopreservation of oocytes and embryos, gamete intrafallopian transfer (GIFT), and microinsemination, have been developed and refined (Table 1). Herein we describe the history of basic research in IVF-ET that led to human applications, how the birth of the first IVF-ET baby was achieved in Japan, the current status of ART in Japan, issues related to ART, and future prospects for ART.

    This study aimed to evaluate the efficacy, safety, and trends in assisted reproductive technology (ART) in Japan. Data pertaining to treatment cycles, pregnancy rate, live birth rate, age distribution, single embryo transfer rate, and multiple pregnancy rate were analyzed for patients registered in the national ART registry system of Japan from 2007 to 2010. The total number of treatment cycles was 161,164, 190,613, 213,800, and 242,161 in 2007, 2008, 2009, and 2010, respectively. The number of ART treatments administered to patients aged ≥40 years was 31.2 %, 32.1 %, 33.4 %, and 35.7 %, respectively, showing an increasing trend from 2007 to 2010. In each of these years, the total pregnancy rate per embryo transfer was 24.4 %, 21.9 %, 22.3 %, and 21.9 % for fresh cycles, respectively, and 32.0 %, 32.1 %, 32.5 %, and 33.7 % for frozen cycles, respectively. The single embryo transfer rate was 49.9 %, 63.6 %, 70.6 %, and 73.0 %, respectively, showing an increasing trend, while the multiple pregnancy rate was 11.5 %, 6.8 %, 5.3 %, and 4.8 %, respectively, showing a decreasing trend. From 2007 to 2010 in Japan, the number of ART treatment cycles, number of elderly patients treated, and the single embryo transfer rate increased, while the multiple pregnancy rate decreased. However, the overall pregnancy rate remained stable during the study period.

    This study presents a method for analyzing workers' behavior using indoor positioning technology and field test in the workplace. Recently, various indoor positioning methods, such as Wi-Fi, Bluetooth low energy (BLE), visible light communication, Japan's indoor messaging system, ultra-wide band (UWB), and pedestrian dead reckoning (PDR), have been investigated. The development of these technologies allows tracking of movement of both people and/or goods in indoor spaces, people and/or goods behavior analysis is expected as one of the key technologies for operation optimization. However, when we use these technologies for human tracking, there are some problem as follows. 1) Many cases need to use dedicated facilities (e.g. UWB). 2) When we use smartphone as sensing device, battery depletion is one of the big problem (especially using PDR). 3) the accuracy is instability for tracking (e.g. Wi-Fi). Based on these matters, in this study we designed and developed an indoor positioning system using BLE positioning. And, we adopted smartphone for business use as sensing device, developed a smartphone application runs on android OS. Moreover, we conducted the field test of developed system at Itoki Corporation's ITOKI Tokyo Innovation Center, SYNQA, office (Tokyo, Japan). Over 40 workers participated in this field test, and worker tracking log data were collected for 6 weeks. We analyzed the characteristics of the workers' behavior using this log data as a prototyping.

    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.

  14. How to recover credibility of nuclear technologies in Japan where people wish to have 'Anshin'

    Although it is inevitable to recover credibility of utilities, there are no clear ways to realize a final target yet. Credibility issue is a very difficult especially in Japan, where the word of 'Anshin' has special importance in the mind of people. In this paper, the word of 'Anshin' in Japan was discussed in order to find out differences in other countries by comparison of culture and customs, especially ways to prepare food, i.e. agriculture and hunting and gathering and so on. The meanings of 'Anshin' were decomposed into several elements, and each element was discussed and clarified. Human factor is important in both operation of plants and risk communication. The philosophy and attitude of COE of utilities are those of very important factors to regain credibility. The utilities' responsibilities are important, but not enough by themselves. In order to assure transparency of information used in risk communication, improvement of people's scientific literacy and their attitude to elect their representatives are absolutely necessary. Especially, risk information related to Level 3 RPA to be opened to public have to be fully transparent. Risk is one of most difficult concept for Japanese people to handle. The reoperation issue of nuclear power plants will involve several difficulties, but challenges to overcome this issue will be a good chance to change a way of decision making in Japan. (author)

    Enhanced surveillance was conducted during the Sports Festival in Tokyo 2013 (September 28-October 14, 2013) for early detection of outbreaks of infectious diseases and other health emergencies. Through this enhanced surveillance, 15 cases were found that required additional gathering of information outside the routine process of creating/evaluating the Daily Report. However, none of these was assessed as critical. Through the enhanced surveillance, we structured a framework that allows for earlier response when detecting aberrations. It includes the role of the Tokyo Metropolitan Government in communications and contacts with relevant parties such as public health centers, as well as in monitoring of surveillance data. However, some issues need to be further considered toward the Tokyo 2020 Olympic and Paralympic Games, such as establishing the criteria for additional response steps, increasing the number of participating bodies in syndromic surveillance, and strengthening of cooperation with related departments, including those for crisis management assuming potential biological/chemical terrorism.

    1989-01-01

    There are growing tensions and frictions between the U.S. and Japan. Among them are science and technology issues that relate to the development of superconductor technology, as well as economic, trade and agricultural issues. The structure of this friction is very complex. There are many interconnected issues that cannot be resolved one by one. This article focuses on the relationship between the U.S. and Japan. Some of the complexities behind the issues are discussed by defining different notions of internationalization and by presenting the positive and negative aspects of the Japanese approach that affects the future cooperation and competition between our nations in the area of superconductivity

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.

    Tanaka, Shoji

    2007-03-01

    From 1960 to 1980, R&D of superconductivity in Japan was carried out mainly to improve A15 superconducting wires and magnets. Improvement of wires were made mainly in the National Institute for Metals, and improvements of superconducting magnets were made in the Japan Atomic Energy Research Institute for future nuclear fusion reactors, the National Railway Laboratory for future maglev trains and also in the Electo-Technical Laboratory for MHD generators. I began the research of BPBO in 1975 and at that time the research of oxide superconductors was limited only to my laboratory in the University of Tokyo. During the study of this new superconductor, we learned quite a lot on how to make ceramic samples, how to measure electrical conductivity and magnetic susceptibility at low temperatures. In 1982, Prof. S. Nakajima organized a rather small group for investigating ``New Superconducting Phenomena,'' and I became a member of the group. In 1985, Nakajima expanded the research group to include more than 5 experimentalists and 5 theoreticians. The title of the research was ``New Superconducting Materials'' and the funds came from the Ministry of Education of Japan. In late October, 1986, we followed the first paper of Bednorz and Muller, and immediately found the material includes high temperature superconductor and reported it to the group meeting held in early November. In early December, we confirmed La2-xBaxCuO4 is the real high temperature superconductor, the critical temperature is 28K. I sent a copy of our paper to Prof. Beasley of California and asked to inform this fact to his colleagues. Asahi Shimbun, the biggest newspaper in Japan announced this in its science section, and then many people knew the high temperature superconductor had been discovered. Then many physicists and chemists rushed to this field very quickly and many kinds of materials were synthesized.

    Japan strictly closed the country to foreigners except for the Dutch and Chinese in the days of Tokugawa Regime for about 200 years (1639-1858). During this period, Japanese neurology made a start. In 1774, five Dutch scholars in Edo (Tokyo at present) translated the Dutch version of a German textbook "Anatomische Tabellen". After the Meiji Restoration, Japan was rapidly westernized. The modern neurology was introduced mainly from Germany, France and the United Kingdom into Japan, and exerted a fruitful influence on the subsequent Japanese neurology. Prof. Hiroshi KAWAHARA published the first textbook of neurology (in Japanese) in 1897. Prof. Kinnosuke MIURA founded the first neurological journal in Japan in 1902. These two pioneers in Japanese neurology had their medical education under Prof. Erwin Baelz at the University of Tokyo during the last-eighteenth century.

    I would like to congratulate INIS on its 45th anniversary. Japan is a founding member of this international cooperation program, and the Japan Atomic Energy Agency (formerly, Japan Atomic Energy Research Institute — JAERI) was appointed as the national center of INIS by the Japanese government. We have contributed to the collection, classification, indexing, abstracting and submission of nuclear literature published in our country, as well as promoted the INIS database within our country. I have been engaged in INIS activities for many years and have a lot of experience with INIS. On the occasion of INIS’ 45th anniversary, I would like to look back on this experience. I started my career at JAERI in 1984. The first regional training seminar for the Far East was held in Tokyo in October 1984. I was assigned to the Library Division of JAERI, but I worked as support staff for the regional training seminar. During the seminar, I had an opportunity to attend the technical tour with the seminar participants to the University of Library and Information Science, research laboratories, etc., in Tsukuba Science City. This was my first involvement with INIS. It was a very impressive and interesting experience

    Drug overdose is a serious public health issue and fatal cases have been reported from various fields of medicine. This case-control analysis assessed the comparison between fatal overdose cases in the special wards of Tokyo Metropolitan area and prescribed psychotropic drugs in Tokyo in 2009-2010. It was suggested that the prescribed drugs serve as a direct cause of death in overdose cases. Furthermore, pentobarbital calcium, chlorpromazine-promethazine-phenobarbital, levomepromazine and flunitrazepam were identified as drugs with a high risk of fatal overdose. It is encouraged to prudently verify the intended application and usage of such psychotropic drugs in each case upon their prescription. This is the first study in Japan to identify psychotropic drugs with a high risk of fatal overdose by case-control study.

    The reactor buildings at the Fukushima Daiichi Nuclear Power Station of Tokyo Electric Power Co., Inc., which was seriously damaged by the Great East Japan Earthquake of March 11, 2011, have been highly contaminated by radioactive materials. To safely and efficiently advance the processes related to the forthcoming decommissioning of the reactors, it is necessary to improve the hazardous environment inside the reactor buildings. During the more than four years that have elapsed since the Great East Japan Earthquake, Toshiba has been implementing various measures to reduce the ambient dose rates inside the reactor buildings through decontamination work and participation in a national project for the development of remote decontamination technologies for reactor buildings. A variety of vehicles and technologies to support decontamination work have been developed through these activities, and are significantly contributing to improvement of the environment inside the reactor buildings.

    In Japan, the number of municipalities that offer free medical care for children has increased. This policy, however, might unintentionally aggravate the overcrowded situation of pediatric ambulatory services in Japan. We investigated the relationship between parents' health-care seeking attitudes according to child symptom severity and the amount of copayment, as well as parents' socioeconomic and demographic factors. We used data for 4385 people from the Japanese Study of Stratification, Health, Income and Neighborhood (J-SHINE), which consisted of stratified random sampling of those aged from 25 to 50 years who lived in Tokyo and neighboring areas. Outcome variables were respondent health-care seeking attitudes toward their children's mild and severe symptoms of cold. Logistic regression models were developed for each dependent variable. A total of 1606 respondents with one or more children under the age of 15 years were included in the analysis. For mild symptoms of cold, no subsidy (OR: 0.51, 95%CI: 0.38-0.69) and partial subsidy (OR, 0.71; 95%CI: 0.54-0.95) were associated with fewer "visit on that day" answers, compared with full subsidy. Income and respondent educational level were not associated with the outcome. For severe symptoms of cold, the OR of no subsidy (0.61; 95%CI: 0.30-1.23) and that of partial subsidy (0.91; 95%CI: 0.40-2.07) were not statistically significant. Imposing a small copayment might prevent visits to medical facilities for mild symptoms of cold, but will not prevent visits for severe symptoms of cold. © 2015 Japan Pediatric Society.

  16. Supermodernity, distraction, schizophrenia: walking in Tokyo & Hong Kong.

    Full Text Available The architecture in a supermodern city has no sense of the place where it is located. This paper discusses how schizophrenia and distraction, through walking, respond to supermodernity by referring to how three dislocated subjects, Fumiya Takemura, Aiichiro Fukuhara and Fai in Tokyo and Hong Kong, are respectively depicted in the novel, Adrift in Tokyo written by Fujita Yoshinaga in 1999, with a film adaptation by Satoshi Miki (2007, and the film To Live and Die in Mongkok directed by Wong Jing in 2009. It suggests that Hong Kong is more supermodern than Tokyo. After his release from prison, Fai in To Live and Die in Mongkok finds that Mongkok is a completely different place from the one in which he used to live. The living conditions are no better than those in the prison. He hallucinates about the past. Adrift in Tokyo can be read as a story about walking. Fukuhara, a debt collector, killed his wife; before surrendering to the police, he orders his debtor, Takemura, to walk with him in Tokyo in order to re-experience the walks he enjoyed with his wife. If Takemura agrees, the debt can be paid off. This paper discusses how the repressed heterogeneous time and place can be approached by walking in a way that the rhythm of life can be (re-experienced; in other words, when the body moves forward physically, the past appears as specter haunting the walker. This paper discusses how Adrift in Tokyo and To Live and Die in Mongkok read cities in distractive and schizophrenic ways. In the film version of Adrift in Tokyo, Takemura’s failed relationship with his father may unconsciously drive him to walk with Fukuhara. The novel may imply that the lost relationship with his mother drives him to walk. The film and the novel both address a kind of locality which should be inseparable from the birth parents. To Live and Die in Mongkok suggests that supermodernity kills mother and father. The Father-son relationship disappears at the very beginning of the

    The 1999 Izumit Earthquake as the destructive earthquake occurred near the Marmara Sea. The Marmara Sea should be focused on because of a seismic gap in the North Anatolian fault. Istanbul is located around the Marmara Sea, so, if next earthquake will occur near Istanbul, fatal damages will be generated. The Japan and Turkey can share our own experiences during past damaging earthquakes and we can prepare for future large earthquakes in cooperation with each other. In earthquakes in Tokyo area and Istanbul area as the destructive earthquakes near high population cities, there are common disaster researches and measures. For disaster mitigation, we are progressing multidisciplinary researches. Our goals of this SATREPS project are as follows, To develop disaster mitigation policy and strategies based on multidisciplinary research activities. To provide decision makers with newly found knowledge for its implementation to the current regulations. To organize disaster education programs in order to increase disaster awareness in Turkey. To contribute the evaluation of active fault studies in Japan. This project is composed of four research groups. The first group is Marmara Earthquake Source region observationally research group. This group has 4 sub-themes such as Seismicity, Geodesy, Electromagnetics and Trench analyses. The second group focuses on scenario researches of earthquake occurrence along the North Anatolia fault and precise tsunami simulation in the Marmara region. Aims of the third group are improvements and constructions of seismic characterizations and damage predictions based on observation researches and precise simulations. The fourth group is promoting disaster educations using research result visuals. In this SATREPS project, we will integrate these research results for disaster mitigation in Marmara region and .disaster education in Turkey. We will have a presentation of the updated results of this SATREPS project.

    Leadership has been argued to be a key component in the transformation of services in the United Kingdom and in Japan. In the UK, local professional networks have developed to provide clinician led care in dentistry; working to develop local plans to deliver improvements in the quality of care for patients. In Japan, the remuneration model for dental care has been revised with the aim to improve the service and tackle the current challenges of population health there. The aim of this study was to use semi-structured interviews and thematic analysis to explore general dental practitioners' (GDPs) understanding of the term 'leadership' and determine whether its meaning is culturally bound. Twelve participants were sampled purposively by the research team; identifying GDPs involved in leadership roles from across Greater Manchester and Tokyo. A set of open-ended questions was developed for semi-structured interviews a priori and the interviews continued until saturation. Interviews were recorded, transcribed verbatim and codes were developed into a coding frame for thematic analysis. Representative quotations are provided in the results. Fourteen codes were identified according to the aims of the study and organised into five overarching themes. 'Leadership as the relationship' was more pronounced among Japanese GDPs, while 'leadership as the individual' was common in GDPs from Greater Manchester. Differences were also found in respect of education and training in leadership. Training was also considered to be important by the GDPs from Japan, while UK GDPs felt leaders were more likely to be influenced by innate qualities. The interdependence of leadership and entrepreneurship was raised by both sets of GDPs. The concept of leadership was considered to be important by GDPs from both Greater Manchester and Tokyo; leadership was seen as providing strategy and direction for a clinical team. However, cultural influences were evident in how this was conceptualised.

    Molecular epidemiological analysis of 96 rabies viruses isolated from animals in Tokyo in the 1950s involves Japanese fixed virus, Komatsugawa, Takamen, and Nishigahara strains. Strains isolated in Tokyo were divided into Tokyo 1 and Tokyo 2, and grouped into a worldwide distribution cluster differing from Takamen and Nishigahara. Tokyo 1 was grouped into the same cluster as viruses isolated from United States west coast dogs in the 1930s and 1940s. Tokyo 2 was grouped into the same cluster as the Komatsugawa strain, also known as a cluster of viruses from the Khabarovsk raccoon dog, and the Lake Baikal stepped fox in Russia. These findings suggest that 1950s Tokyo rabies viruses were related to those in Russia and the USA.

    It is unclear whether the prehospital termination of resuscitation (TOR) rule is applicable in specific situations such as in areas extremely dense with hospitals. The objective of the study is to assess whether the prehospital TOR rule is applicable in the emergency medical services system in Japan, specifically, in an area dense with hospitals in Tokyo. This study was a retrospective, observational analysis of a cohort of adult out-of-hospital cardiopulmonary arrest (OHCA) patients who were transported to the University of Tokyo Hospital from April 1, 2009, to March 31, 2011. During the study period, 189 adult OHCA patients were enrolled. Of the 189 patients, 108 patients met the prehospital TOR rule. The outcomes were significantly worse in the prehospital TOR rule-positive group than in the prehospital TOR-negative group, with 0.9% vs 11.1% of patients, respectively, surviving until discharge (relative risk [RR], 1.11; 95% confidence interval [CI], 1.03-1.21; P = .0020) and 0.0% vs 7.4% of patients, respectively, discharged with a favorable neurologic outcome (RR, 1.08; 95% CI, 1.02-1.15; P = .0040). The prehospital TOR rule had a positive predictive value (PPV) of 99.1% (95% CI, 96.3-99.8) and a specificity of 90.0% (95% CI, 60.5-98.2) for death and a PPV of 100.0% (95% CI, 97.9-100.0) and a specificity of 100.0% (95% CI, 61.7-100.0) for an unfavorable neurologic outcome. This study suggested that the prehospital TOR rule predicted unfavorable outcomes even in an area dense with hospitals in Tokyo and might be helpful for identifying the OHCA patients for whom resuscitation efforts would be fruitless. © 2013.

    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.

    Medical schools at the beginning of Meiji era were diverse, both in regard to their founders and their methods of education, frequently employing foreign teachers of various nationalities. In 1871, German teachers were appointed to organize medical education at the medical school of the University of Tokyo. The anatomical education at the school was conducted by German teachers, i.e. Miller (1871-1873), Dönitz (1873-1877), Gierke (1877-1880) and Disse (1880-1885), followed by Koganei, who returned from the study in Germany. At the first meeting of Japanese Association ofAnatomists in 1893 [Meiji 26], the Japanese anatomy teachers met together and most of them were graduates of the University of Tokyo or fellows of its anatomy department. Before 1877 [Meiji 10], the anatomy books were mainly translated from English books, and foreign teachers of various nationalities were employed in many medical schools in Japan. After 1877 [Meiji 10], the anatomy books based on the lectures by German teachers at the University of Tokyo were published. The anatomy books after 1887 [Meiji 20] were written based on German books, and the German anatomical terms were utilized. After 1905 [Meiji 38], the original Japanese anatomy books appeared, employing international anatomical terms. In the Meiji 10s the anatomy teachers and anatomy textbooks spread from the University of Tokyo to the medical schools in Japan as the number of medical schools increased temporally. In the Meiji 20s the five national and three public medical schools in addition to the University of Tokyo provided substantial anatomy education including dissection course. Even in the early Meiji 20s these medical schools supplied only half of the newly licensed doctors, and the others were supplied through the national examination after preparatory education at private medical schools without opportunity of substantial anatomy education including dissection course.

    In February 2017, four food poisoning outbreaks occurred in Tokyo, involving ten schools. Shredded dried laver seaweed processed by a single food manufacturer in December 2016 was provided in common for the school meals that caused all four outbreaks. Of 4,209 persons exposed, 1,193 (28.3%) had symptoms of gastroenteritis. Norovirus (NoV) GII was detected in 207 (78.1%) of 265 cases by real-time RT-PCR. Thirty-one shredded dried laver seaweed samples were examined and seven (22.6%) of them were positive for NoV GII. PCR fragments of NoV ORF1/2 junction region (302 bp) from seven shredded dried laver seaweed samples and 20 clinical samples derived from the four outbreaks were sequenced. All of them displayed complete homology, and the genotype was classified as GII.17. A nearly full-length sequence (7,420 bp) of NoV RNA derived from a case was obtained by next-generation sequencer analysis and phylogenetic analysis indicated that this strain belongs to the same cluster as Hu/GII/JP/2015/GII.P17_GII.17/Kawasaki308. Thus, our investigation elucidated that the causative agent of these four serial food poisoning outbreaks was NoV GII.17 and the infectious source was a single batch of shredded dried laver seaweed. The water activity of the shredded dried laver seaweed was found to be 0.119 to 0.129. It was epidemiologically clarified that NoV does not lose infectivity for about two months even in the dry state. We conclude that a large diffuse outbreak of food poisoning caused by NoV GII.17 contamination of shredded dried laver seaweed had occurred in Tokyo. Our elucidation of the causative agent indicated that the food poisoning outbreaks in multiple areas of Japan, including Tokyo, during January to February 2017 were caused by the same contaminated food.

    Evidence linking air pollution with adverse health outcomes is accumulating. However, few studies have adopted a quasi-experimental design to evaluate whether decline in air pollution from regulatory action improves public health. We evaluated the effect of a diesel emission control ordinance introduced in 2003 on mortality rates in 23 wards of the Tokyo metropolitan area, Japan, from October 2000 to September 2012, taking into account change in mortality rates in a reference population (Osaka) with a introduction of such a regulation in 2009. We obtained daily counts of all-cause and cause-specific mortality and concentrations of nitrogen dioxide (NO2) and particulate matter less than 2.5 μm in diameter (PM2.5) during the study period. We employed interrupted time-series analysis to analyze the data. Decline in NO2 during the study period was similar in the two areas, while decline in PM2.5 and the improvement in age-standardized mortality rates were greater in Tokyo's 23 wards compared with Osaka. Even after adjusting for age-standardized mortality rates in Osaka, percent changes in mortality between the first 3-year interval (October 2000 to September 2003) and the last 3-year interval (October 2009 to September 2012) were -6.0% for all causes, -11% for cardiovascular disease, -10% for ischemic heart disease, -6.2% for cerebrovascular disease, -22% for pulmonary disease, and -4.9% for lung cancer. We did not observe a decline in mortality from other causes. This quasi-experimental study in Tokyo suggests that emission control was associated with improvements in both air quality and health outcomes.

    The March 11, 2011 Tohoku-oki earthquake brought a great impact to the Tokyo metropolitan area in both seismological aspect and seismic risk management although Tokyo is located 340 km from the epicenter. The event generated very strong ground motion even in the metropolitan area and resulted severe requifaction in many places of Kanto district. National and local governments have started to discuss counter measurement for possible seismic risks in the area taking account for what they learned from the Tohoku-oki event which is much larger than ever experienced in Japan Risk mitigation strategy for the next greater earthquake caused by the Philippine Sea plate (PSP) subducting beneath the Tokyo metropolitan area is of major concern because it caused past mega-thrust earthquakes, such as the 1703 Genroku earthquake (M8.0) and the 1923 Kanto earthquake (M7.9). An M7 or greater (M7+) earthquake in this area at present has high potential to produce devastating loss of life and property with even greater global economic repercussions. The Central Disaster Management Council of Japan estimates that an M7+ earthquake will cause 11,000 fatalities and 112 trillion yen (about 1 trillion US$) economic loss. In order to mitigate disaster for greater Tokyo, the Special Project for Earthquake Disaster Mitigation in the Tokyo Metropolitan Area was launched in collaboration with scientists, engineers, and social-scientists in nationwide institutions. We will discuss the main results that are obtained in the respective fields which have been integrated to improve information on the strategy assessment for seismic risk mitigation in the Tokyo metropolitan area; the project has been much improved after the Tohoku event. In order to image seismic structure beneath the Metropolitan Tokyo area we have developed Metropolitan Seismic Observation network (MeSO-net; Hirata et al., 2009). We have installed 296 seismic stations every few km (Kasahara et al., 2011). We conducted seismic

    (1) The first domestic-made 1100-MW(e) BWR in Japan commenced commercial operation in April 1982. The unit is the leading one of the subsequent three in Fukushima Daini nuclear power station owned by the Tokyo Electric Power Company Inc. (Tepco). Based on the accumulated construction and operation experience of 500-MW(e) and 800-MW(e) class BWRs, improvements in various aspects during both the design and construction stages were introduced in core and fuel design with advanced gadolinia distribution, reactor feedwater treatment technology for crud reduction, a radwaste island, control and instrumentation to cope with the lessons learned through Three Mile Island assessment etc. (2) Based on many operating experiences with BWRs, an improved BWR core, which has easier operability and higher load factor than the conventional core, has been developed. The characteristic of the improved core is ''axially two-zoned uranium enrichment distribution''; the enrichment of the upper part of the fuel is slightly higher than that of the lower part. Through the improved core it became possible to optimize the axial power flattening and core reactivity control separately by axial enrichment distribution and burnable poison content. The improved fuels were loaded into operating BWRs and successfully proved the performance by this experience. (3) To shorten annual outage time, to reduce radiation exposure, to save manpower, and to achieve high reliability and safety of inspection operation, the remote automatic service and inspection equipment were developed in Japan. This paper presents the concept, distinctive features, and actual operation experience of the automatic refuelling machine, control-rod drive (CRD) remote-handling machine, improved main steam line isolation plug, and the automated ultrasonic inspection system with a computerized data processing unit, which have been developed by Hitachi, Ltd. with excellent results.

    DNR is the technique to obtain radiography image continuously using a imaging system and Japan is the leading country in this field. Considering that no research has been performed to obtain quantitative parameters using DNR in Korea, it was necessary to establish a cooperative structure with Japanese experts and to develop the DNR technique throughout this project. The objectives of the project were to conduct 4 cooperative experiments using the HANARO BNCT facility and to establish a relationship with Japanese experts which makes it possible to maintain continuous communication. 4 experiments such as the void fraction and flow pattern measurement in a channel simulating HANARO fuel channel, observation of flow field in Pb/Bi field and the observation of cavity in a diesel engine nozzle were successfully completed. Also, the continuos communication and cooperation between the experts of two countries will be made. In this sense, this project is believed as a model project to use the mega research facility such as HANARO for the international cooperation

    The demand for both data quality and the range of Cloud-to-Ground (CG) lightning parameters is highest for forensic applications within the electric utility industry. For years, the research and operational communities within this industry in Japan have pointed out a limitation of these LLS networks in the detection and location of damaging (high-current and/or large charge transfer) lightning flashes during the winter months (so-called “Winter Lightning”). Most of these flashes appear to be upward-connecting discharges, frequently referred to as “Ground-to-Cloud” (GC) flashes. The basic architecture and design of Vaisala’s new LS700x lightning sensor was developed in-part to improve detection of these unusual and complex flashes. This paper presents our progress-to-date on this effort. We include a review of the winter lightning detection problem, an overview of the LS700x architecture, a discussion of how this architecture was exploited to evaluate and improve performance for winter lightning, and a presentation of results-to-date on performance improvement. A comparison of GC detection performance between Tohoku’s operational 9-sensor IMPACT (ALDF 141-T) LLS and its 6-sensor LS700x research network indicates roughly a factor-of-two improvement for this class of discharges, with an overall detection of 23/24 (96%) of GC flashes.

    Several recent improved methods for the EGFM are introduced in order to avoid artificial holes seen in the synthetic acceleration spectrum. Furthermore evaluation of input ground motions at Wolsung NPP are performed by varying the source parameters that may control the high-frequency wave radiation and the deviation of the synthetic motions are revealed. The PSHA case studies for four NPP sites (Wolsung, Kori, Uljin, Younggwang) are performed. In the analysis, site-specific attenuation equations developed for Korean NPP sites are employed, and the seismic hazards for the target sites are evaluated in the case where the four kind of seismic source models are considered. Moreover, the PSHA for Wolsung and Younggwang are conducted by using the site-specific attenuation equation with the index of response spectra and the uniform hazard spectra are evaluated for the two sites. The supporting tool for seismic response analysis and the evaluation tool for evaluating annual probability of failure were integrated in the frame of the seismic risk assessment system. Then, the tools were applied to the seismic risk assessment of the conventional EDG and isolated EDG. General information such as earthquake parameters and regional distribution of seismic intensity is summarized on the 2005 West Off Fukuoka earthquake. Then, the observed strong motion records in Japan and Korea sites are compiled, and regional distribution of peak accelerations are represented. Moreover, the peak accelerations of the records are compared with the values estimated from the existing attenuation equations.

  15. Earthquake Prediction Techniques: Their Application in Japan

    Japan is serious about solving the earthquake prediction problem. A well-organized and well-funded program of research has been under way for almost 20 years in pursuit of the national goal of protecting the dense population of this earthquake-prone country through reliable predictions.This rather amazing book, edited by Toshi Asada, retired director of the Geophysical Institute of the University of Tokyo, has been written by 10 scientists, each of whom has made important contributions to earthquake science, but who have not been known in the past as principal spokesmen for the Japanese earthquake prediction program. The result is a combination of a very readable tutorial presentation of basic earthquake science that will make the book understandable to the nonspecialist, a good summary of Japanese data and research conclusions, and a bare-knuckles appraisal of current philosophy and strategy for prediction in Japan.

    Tokyo Metropolitan area is situated in tectonically complex region; both the Pacific (PAC) and Philippine Sea (PHS) plates are subducting from east and south, respectively, beneath the Kanto region. As a result, various types of earthquakes occur in this region; i.e., shallow crustal earthquakes, intraplate (slab) earthquakes within PHS, within PAC, and interplate earthquakes between continental plate and PHS, and between PHS and PAC. Among these, the largest earthquakes are Kanto earthquakes (M~8) occurring between the continental plate and PHS. The average recurrence interval is estimated to be 200 - 400 years (Earthq. Res. Comm., 2004), and hence, urgency of the next Kanto earthquake is thought to be low considering the lapse time (~87 yrs.) from the most recent Kanto earthquake in 1923. However, urgency of the other types of earthquakes with M~7 is high; Earthq. Res. Comm. (2004) calculated the probability of occurrence during the next 30 years as 70 %, based on the facts that five M~7 earthquakes (i.e., the 1894 Meiji-Tokyo, 1895 and 1921 Ibaraki-Ken-Nanbu, 1922 Uraga channel and 1987 Chiba-Ken Toho-Oki earthquakes) occurred since 1885. However, types of earthquakes are not well known especially for the 1894 Meiji-Tokyo and 1895 Ibaragi-Ken-Nanbu earthquakes due to low quality of data. Thus, it is important to classify these earthquakes into above-described intraplate or interplate earthquakes and to estimate their occurrence frequency. Ishibe et al. (2009a, 2009b) compiled previous studies and data for these five earthquakes. In this study, we report the preliminary result of focal depth and mechanism for the 1895 and 1921 Ibaraki-Ken-Nanbu earthquakes. The epicenter of the 1895 Ibaraki-Ken-Nanbu earthquake (M 7.2; Utsu, 1979) is discussed by various studies (e.g., Usami, 1973; Ishibashi, 1975; Katsumata, 1975; Utsu, 1979). However, few studies have discussed the hypocentral depth. The hypocentral depth is estimated to be 75 ~ 85 km using S-P time at Tokyo

    The Imperial College of Engineering (ICE or Kobu-Daigakko) in Tokyo, founded in 1873 under the auspices of the Ministry of Public Works, was one of the most prominent modern institutions of engineering education in early Meiji Japan. Previous studies have revealed that the ICE offered large scale practical training programs at enterprises of the Ministry, which sometimes lasted several months, and praised their ideal combination of theory and practice. In reality, it has been difficult to evaluate the quality of education at the ICE mainly because of scarcity of sources. ICE students published a collection of memoirs for alumni members, commemorating the fiftieth-year of the history of the Tokyo Imperial University. Drawing on the previously neglected collection of students' memoires, this paper appraises the education of civil engineering offered by the ICE. The paper also compares this collection with other official records of the college, and confirms it as a reliable source, even though it contains some minor errors. The author particularly uses the memoirs by Ayahiko Ishibashi, one of the first graduates from its civil engineering course, who left sufficient reminiscences on education that he received. This paper, as a result, illustrates that the main practical training for the students of civil engineering was limited to designing process, including surveying. Furthermore, practical training that Ishibashi received at those enterprises often lacked a plan, and its effectiveness was questionable.

    Chemical agents have been used previously in wartime on numerous occasions, from World War I to the Gulf War. In 1994 and 1995, sarin nerve gas was used first in peacetime as a weapon of terrorism in Japan. The Tokyo subway sarin attack was the first large-scale disaster caused by nerve gas. A religious cult released sarin gas into subway commuter trains during morning rush hour. Twelve passengers died and about 5500 people were harmed. Sarin is a highly toxic nerve agent that can be fatal within minutes to hours. It causes the clinical syndrome of cholinergic hyperstimulation by inhibition of the crucial enzyme acetylcholinesterase. Therapy of nerve agent toxicity is divided into three categories, decontamination, respiratory support, and antidotes. All of these therapies may be given simultaneously. This article reviews toxicology and management of this acute chemical emergency. To help minimize the possible catastrophic impact on the public, we make several recommendations based on analysis of the Tokyo subway sarin attack and systematically review the current scientific literature.

    The overall aim of the Co-operative Program has been to promote the exchange of information on technology for the management of High-Level Wastes (HLW) and to encourage research and development relevant to such technology. During the 13 years that the Program has been carried out, HLW management strategies have matured and developed internationally, and Japan has commenced construction of a domestic reprocessing and vitrification facility for HLW. The HLW management strategy preferred is a national decision. Many countries are using vitrification, direct disposal of spent fuel or a combination of both to handle their existing wastes whereas others have deferred the decision. The work carried out in the Co-operative Program provides strong scientific evidence that the durability of ceramic waste forms is not significantly affected by radiation damage and that high loadings of actinide elements can be incorporated into specially designed ceramic waste forms. Moreover, natural minerals have been shown to remain as closed systems for U and Th for up to 2.5 b y. All of these results give confidence in the ability of second generation waste forms, such as Synroc, to handle future waste arisings that may not be suitable for vitrification 87 refs., 15 tabs., 22 figs.

    In order to promote energy conservation in developing countries, the gist of Japanese energy saving technologies was edited into a database. The Asian territory is expected of remarkable economic development and increased energy consumption including that for fossil fuels. Therefore, this project of structuring a database has urgent importance for the Asian countries. New and wide-area discussions were given to revise the 1995 edition. The committee was composed of members from high energy consuming areas such as iron and steel, paper and pulp, chemical, oil refining, cement, electric power, machinery, electric devices, and industrial machinery industries. Technical literatures and reports were referred to, and opinions were heard from specialists and committee members representing the respective areas. In order to reflect the current status and particular conditions in specific industrial areas, additions were given under the assistance and guidance from the specialists. The energy saving technologies recorded in the database may be called small to medium scale technologies, with the target placed on saving energy by 10% or more. Small-scale energy saving technologies were omitted. Flow charts for manufacturing processes were also added. (NEDO)

    At 2:46 pm on March 11, 2011, a huge earthquake (M 9.0) occurred off the Pacific coast of Tohoku Region, Japan. The subsequent Tsunamis hit the coasts and seriously damaged fishing villages and towns in the area. Tohoku Region faces Northwestern Pacific where is one of the most productive oceans on the Earth. Then, what happened to the marine ecosystems in the Tohoku Region? What happened to the fishery bioresources? What is the mechanism to sustain high productivity in the Region? Is the ecosystem restoring after 4 years? What is required for the recovery of fisheries in the area? In order to answer these questions, the 10 years research project, TEAMS (Tohoku Ecosystem-Associated Marine Sciences) was launched in January 2012 funded by MEXT (Ministry of Education, Culture, Sports, Science and Technology, Japan) to conduct comprehensive research on the area. Tohoku University (TU), Atmosphere and Ocean Research Institute, the University of Tokyo (AORIUT), Japan Agency for Marine-Earth Science and Technology (JAMSTEC), and 25 other institutions are conducting research for this project in close association with local government and fishery people. Currently, approximately 400 people (200 scientists, 160 students and others) covering physical, chemical, biological, and geological sciences including modeling take part in the project from all over Japan.

    Although the number of outbreaks caused by Yersinia enterocolitica has been very small in Japan, 4 outbreaks were occurred during the 2 years between 2012 and 2013. We describe herein 2 outbreaks which were examined in Tokyo in the present study. Outbreak 1: A total of 39 people (37 high school students and 2 staff) stayed at a hotel in mountain area in Japan had experienced abdominal pain, diarrhea and fever in August, 2012. The Y. enterocolitica serogroup O:8 was isolated from 18 (64.3%) out of 28 fecal specimens of 28 patients. The infection roots could not be revealed because Y. enterocolitica was not detected from any meals at the hotel or its environment. Outbreak 2: A total of 52 students at a dormitory had diarrhea and fever in April, 2013. The results of the bacteriological and virological examinations of fecal specimens of patients showed that the Y. enterocolitica serogroup O:8 was isolated from 24 fecal specimens of 21 patients and 3 kitchen staff. We performed bacteriological and virological examination of the stored and preserved foods at the kitchen of the dormitory to reveal the suspect food. For the detection of Y. enterocolitica, food samples. together with phosphate buffered saline (PBS) were incubated at 4 degrees C for 21 days. Then, a screening test for Y. enterocolitica using realtime-PCR targeting the ail gene was performed against the PBS culture. One sample (fresh vegetable salad) tested was positive on realtime-PCR. No Y. enterocolitica was isolated on CIN agar from the PBS culture because many bacteria colonies other than Y. enterocolitica appeared on the CIN agar. After the alkaline-treatments of the culture broth or the immunomagnetic beads concentration method using anti-Y. enterocolitica O:8 antibodies, Y. enterocolitica O:8 which was the same serogroup as the patients' isolates was successfully isolated from the PBS culture. The fresh vegetable salad was confirmed as the incrimination food of this outbreak.

    The promotion of self-medication by pharmacies, with the aim of encouraging a patient's self-selection of proper OTC drug, is written about in the national action plan "Japan is Back". The subject of self-medication has been improved in the 2013 revised edition of "Model Core Curriculum for Pharmaceutical Education". At Tokyo University of Pharmacy and Life Sciences, the systematic education of self-medication was started from the onset of the six-year course in the third, fourth and fifth grade. We introduce here a new approach in our systematic education of self-medication. In the practice of the fourth grade, groups of around 5-6 students are formed. The pharmacy students assume various roles-of pharmacist, rater, observer, and chairman-and perform role-playing. We prepared a standardized patient (SP) showing various symptoms. The student of the role of pharmacist asks about the SP's symptoms, chooses an OTC drug suitable for the SP, and explains the OTC drug to the SP. After the role-playing, those in the roles of rater, observer, SP, and faculty give feedback to the student who played the role of pharmacist. Because we conduct this role-playing using SPs with a variety of symptoms, we can create a situation similar to a real drugstore.

    The temporal variation of the radon concentration, and the radon and thoron concentrations every 3 months for a year were measured using two types of devices in a landmark skyscraper, the Tokyo Metropolitan Government Daiichi Building. In the measurement of temporal variation of the radon concentration using a pulse type ionization chamber, the average radon concentration was 21 ± 13 Bq m -3 (2-68 Bq m -3 ). The measured indoor radon concentration had a strong relationship with the operation of the mechanical ventilation system and the activities of the office workers. The radon concentration also increased together with temperature. Other environmental parameters, such as air pressure and relative humidity, were not related to the radon concentration. In the long-term measurements using a passive radon and thoron discriminative monitor, no seasonal variation was observed. The annual average concentrations of radon and thoron were 16 ± 8 and 16 ± 7 Bq m -3 , respectively. There was also no relationship between the two concentrations. The annual average effective dose for office workers in this skyscraper was estimated to be 0.08 mSv y -1 for 2000 working hours per year. When considering the indoor radon exposure received from their residential dwellings using the annual mean radon concentration indoors in Japan (15.5 Bq m -3 ), the annual average effective dose was estimated to be 0.37 mSv y -1 . This value was 31 % of the worldwide average annual effective dose. (author)

    Background Few studies have investigated ambulance utilization in people aged 85 years or older, ie, the oldest old. Methods We conducted a 1-year population-based observational study of patients transported by ambulance to emergency departments in Tokyo, Japan, which has a population of about 12 million. Demographic data, symptoms/events associated with ambulance transport, and the proportion of hospital admissions were recorded. Transport rates by age and sex were calculated using data for the background population and ambulance transports, and the 10 most frequent symptoms/events requiring transport were compared between the oldest old and those aged 65 to 84 years. Results Of the 642 764 patients who were transported to hospitals by ambulances, 59 570 (9%) were aged ≥85 years; 64% were women. The annual ambulance transport rate for this population was 250 per 1000/year and was significantly greater than the rate (90 per 1000/year) for those aged 65 to 84 years. The highest rate was for men aged 85 to 99 years (292 per 1000/year). Among the oldest old, the most frequent reason for ambulance transport was fall (38.5 per 1000/year), and the symptom most likely to result in hospital admission was dyspnea. Conclusions The ambulance transport rate for the oldest old was high, particularly among men aged ≥95 years. To reduce the need for ambulance transport among the oldest old, preventive care is needed to reduce falls and acute exacerbations of cardiac and respiratory disorders. PMID:20814165

    More than 5,000 passengers on Tokyo subway trains were injured with toxic chemicals including the nerve gas "sarin" on March 20, 1995. The purpose of this study was to identify the effect of sarin exposure on insomnia in a cross-sectional study. A self-administered questionnaire concerning sleep-related items was distributed to victims of sarin exposure in October and November, 2003. Questionnaires were completed by 161 of the 163 participants (98.8%), who were selected from 1,500 subjects. Among them, the authors selected 75 women 30 to 69 years of age. Control participants were collected from inhabitants living in Maebachi City, Gunma Prefecture, Japan. For the younger exposed group (under 50 yr. of age), percentages of poor sleep, difficulty falling asleep, intermittent awakening, early morning awakening, a feeling of light overnight sleep, and insomnia were significantly higher than those for the control group. In contrast, the older exposed group (ages 50 to 69 years) had significantly higher prevalence of poor sleep, a feeling of light overnight sleep, and early morning awakening for the exposed group when compared with the control group. The high prevalence of insomnia and insomnia-related factors for victims especially under 50 years of age suggests a need for research on sleep quality after sarin exposure. Although posttraumatic stress disorder is assumed to be a psychological effect of exposure to a toxic substance, a cause-and-effect relationship has not been established.

    Cute-1.7+APD II is the 3rd satellite developed by the Laboratory for Space Systems at the Tokyo Institute of Technology. Cute-1.7+APD II is the current successor to Cute-1.7+APD. This new satellite is based on its predecessor but has some modifications to increase its reliability and robustness against radiation effects, electrical power shortage and so on. The satellite was launched by an ISRO PSLV-C9 rocket on April 28, 2008 and has operated for more than 9 months. Throughout its operation, many missions such as attitude determination and control experiments, scientific observations, photographing and communication experiments have been conducted. In this paper an overview of the Cute-1.7 series and configurations, modifications and operation results of Cute-1.7+APD II are introduced.

    BCG, only vaccine available to prevent tuberculosis, was established in the early 20th century by prolonged passaging of a virulent clinical strain of Mycobacterium bovis. BCG Tokyo-172, originally distributed within Japan in 1924, is one of the currently used reference substrains for the vaccine. Recently, this substrain was reported to contain two spontaneously arising, heterogeneous subpopulations (Types I and II). The proportions of the subpopulations changed over time in both distributed seed lots and commercial lots. To maintain the homogeneity of live vaccines, such variations and subpopulational mutations in lots should be restrained and monitored. We incorporated deep sequencing techniques to validate such heterogeneity in lots of the BCG Tokyo-172 substrain without cloning. By bioinformatics analysis, we not only detected the two subpopulations but also detected two intrinsic variations within these populations. The intrinsic variants could be isolated from respective lots as colonies cultured on plate media, suggesting analyses incorporating deep sequencing techniques are powerful, valid tools to detect mutations in live bacterial vaccine lots. Our data showed that spontaneous mutations in BCG vaccines could be easily monitored by deep sequencing without direct isolation of variants, revealing the complex heterogeneity of BCG Tokyo-172 and its daughter lots currently in use.

    We report on the results of emergency monitoring of environmental radiation in Tokyo after the severe accident at the Fukushima Daiichi Nuclear Power Plant, triggered by the Great East Japan Earthquake and the resulting tsunami on the 11th March 2011. We collected airborne dust samples at the Setagaya and Koto districts of Tokyo. The concentrations of radionuclides were measured by a Ge semiconductor detector. The highest concentrations of major fission products were detected at 10:00-11:00 a.m. on the 15th March 2011. The detected concentrations were: 2.4×10 2 Bq/m 3 of 131 I, 6.4×10 1 Bq/m 3 of 134 Cs, and 6.0×10 1 Bq/m 3 of 137 Cs. The concentration of 131 I fell to undetectable levels by June 2011. In contrast, 134 Cs and 137 Cs were detected intermittently for one year. Based on the results on the concentrations of detected nuclides, the public internal doses due to inhalation were estimated on the assumption that those in the affected area stayed outdoors continuously for the period from the 13th March 2011 to the 12th March 2012 in the Tokyo metropolitan area. The committed effective dose due to inhalation for adults was estimated to be 25 μSv. (author)

    On March 11, 2011, the Tohoku-Pacific Ocean earthquake (magnitude 9.0) struck the eastern part of Japan. Despite being far from the epicenter of the catastrophic earthquake, the effects were strongly felt in Tokyo, and the aftershocks continued for several months. There are no reports regarding the influence of earthquakes on migraine medication. The aim of our study was to determine the impact of earthquakes on prophylactic therapy with lomerizine in patients with migraine in Tokyo. The study included patients with migraine who were admitted to outpatient clinics in Tokyo between January 2010 and July 2010 or between January 2011 and July 2011 and who were prescribed lomerizine prophylactically for headache by specialists. We investigated clinical factors from the medical records for 26 of these patients. The study population included 10 patients in 2010 and 16 patients in 2011. The frequency of headaches was reduced to under 5 days/month during February in both the groups. Compared to 2010, the frequency of headaches significantly increased in 2011 in March, April and May. Patients with migraine were sensitive to exposure to the earthquake and their headaches worsened despite successful prophylactic treatment with lomerizine before the Tohoku-Pacific Ocean earthquake. © 2014 S.

    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

    The status of American competitiveness in high technology, and in particular the semiconductor industry, has been the subject of concern for some time now.1 With the rise of Japanese manufactures to preeminence in the manufacturing of DRAM (Dynamic Random Access Memory) chips during the 1980's, the fundamental assumptions of modern economic theory have been called into question.2 Various factors have been cited by various authors to account for the recent rise in Japanese competitiveness, including industrial policies of the Japanese government, differences in the cost of capital, investments in research and development, and the requirement of American companies to post financial results quarterly.3 There is, however, a real need for concrete case studies, which can examine the actual history of a technology and establish mechanisms of cause and effect.

  18. Nuclear power in Japan

    1990-01-01

    The Japanese movement against nuclear energy reached a climax in its upsurge in 1988 two years after the Chernobyl accident. At the outset of that year, this trend was triggered by the government acknowledgement that the Tokyo market was open to foods contaminated by the fallout from Chernobyl. Anti-nuclear activists played an agitating role and many housewives were persuaded to join them. Among many public opinion surveys conducted at that time by newspapers and broadcasting networks, I would like to give you some figures of results from the poll carried out by NHK: Sixty percent of respondents said that nuclear power 'should be promoted', either 'vigorously' 7 or 'carefully' 53%). Sixty-six percent doubted the 'safety of nuclear power', describing it as either 'very dangerous' 20%) or 'rather dangerous' (46%). Only 27% said it was 'safe'. In other words, those who acknowledged the need for nuclear power were almost equal in number with those who found it dangerous. What should these figures be taken to mean? I would take note of the fact that nearly two-thirds of valid responses were in favor of nuclear power even at the time when public opinion reacted most strongly to the impact of the Chernobyl accident. This apparently indicates that the majority of the Japanese people are of the opinion that they would 'promote nuclear power though it is dangerous' or that they would 'promote it, but with the understanding that it is dangerous'. But the anti-nuclear movement is continuing. It remains a headache for both the government and the electric utilities. But we can regard the anti-nuclear movement in Japan as not so serious as that faced by other industrial nations

    Meeting the 2-degree global warming target requires wide adoption of low-carbon energy technologies. Many such technologies rely on the use of precious metals, however, increasing the dependence of national economies on these resources. Among such metals, those with supply security concerns are referred to as critical metals. Using the Policy Potential Index developed by the Fraser Institute, this study developed a new footprint indicator, the mining risk footprint (MRF), to quantify the mining risk directly and indirectly affecting a national economy through its consumption of critical metals. We formulated the MRF as a product of the material footprint (MF) of the consuming country and the mining risks of the countries where the materials are mined. A case study was conducted for the 2005 Japanese economy to determine the MF and MRF for three critical metals essential for emerging energy technologies: neodymium, cobalt and platinum. The results indicate that in 2005 the MFs generated by Japanese domestic final demand, that is, the consumption-based metal output of Japan, were 1.0 × 10(3) t for neodymium, 9.4 × 10(3) t for cobalt, and 2.1 × 10 t for platinum. Export demand contributes most to the MF, accounting for 3.0 × 10(3) t, 1.3 × 10(5) t, and 3.1 × 10 t, respectively. The MRFs of Japanese total final demand (domestic plus export) were calculated to be 1.7 × 10 points for neodymium, 4.5 × 10(-2) points for cobalt, and 5.6 points for platinum, implying that the Japanese economy is incurring a high mining risk through its use of neodymium. This country's MRFs are all dominated by export demand. The paper concludes by discussing the policy implications and future research directions for measuring the MFs and MRFs of critical metals. For countries poorly endowed with mineral resources, adopting low-carbon energy technologies may imply a shifting of risk from carbon resources to other natural resources, in particular critical metals, and a trade

    One of the most significant effects of the M9.0 Tohoku, Japan earthquake of March 11, 2011 is the now well-known long duration (>10 minutes) shaking of buildings in Japan – particularly those in Tokyo (~350-375 km from the epicenter) and in places as far as Osaka (~770 km from the epicenter). Although none collapsed, the strong shaking caused many tall buildings not to be functional for days and weeks.

    The aim of this study was to evaluate factors associated with the incidence of erosive tooth wear (ETW) among adults at different ages in Tokyo using multifactorial logistic regression analysis. The study sample consisted of a total of 1108 subjects aged 15 to 89 years in Tokyo, Japan. Two examiners evaluated ETW in a full-mouth recording. The subjects were asked to complete a self-administered daily diet, habit, and health condition questionnaire. Subjects who had frequent acid consumption or gastric reflux and at least one tooth with initial enamel wear were placed in the ETW-positive group, and the remainder of the subjects was placed in the ETW-negative group. Logistic regression analyses were carried out to identify factors collectively associated with ETW. Logistic regression analysis showed that greater frequencies of carbonated or sports drink consumption were associated with higher incidence of ETW for all age groups except for 70-89 years. Adults in the 30-39-year group who reported suffering from heartburn were about 22.3 times more likely to develop ETW, while 40-49-year adults who had repeated vomiting were about 33.5 times more likely to exhibit ETW compared with those who did not experience vomiting. Age-specific dietary habits were clearly observed among adults at different ages in Tokyo, and there were significant differences in intrinsic and extrinsic factors between ETW-positive and ETW-negative groups for each age group. Both greater frequency of carbonated and sports drink consumption were associated with higher incidence of ETW among adults at different ages in Tokyo.

    Improvement in the health of older people and changes in their lifestyles necessitate a scale that can better measure their competence at a higher level. This study describes the development process of the Japan Science and Technology Agency Index of Competence (JST-IC) by (a) refining conceptual definitions and developing preliminary items and (b) examining the basic properties of the items. Participants were 1,253 septuagenarians (539 men and 714 women) living in communities, who were asked to judge whether they were independent via 88 items. To examine the basic properties of the preliminary items, five different analyses were conducted. Thirty-four items were considered as inappropriate (6 overlapped between the analyses): (a) 9 due to very high or low ratios of responders who answered "yes," (b) 4 due to gender or regional differences, (c) 5 due to their weak association with health status, (d) 9 due to low communalities in factor analysis, and (e) 13 due to redundancy of meaning with other items. Conceptual definitions and preliminary items were developed, and the basic properties of the items were examined to create the JST-IC. The next step would be to screen the remaining 54 items to create the final version of the scale.

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

    About high-level radioactive waste disposal, the general invitation in a voluntary approach for selection of ''preliminary investigation areas'' which is the 1 st step of the stepwise site selection by Nuclear Waste Management Organization of Japan is started. On the other hand, about low-level radioactive waste disposal, several kinds of investigation for the burial disposal approach of the underground tunnel facility system in about 50-100 m depth below ground surface have been performed for disposing of high βγ radioactive wastes. For carrying forward each disposal project of these radioactive wastes, the integration of the state-of-the-art technology in an interdisciplinary broad research field is indispensable. Especially the role that civil engineering can play in fields, such as investigation, design, development of new materials and performance assessment for underground disposal facility is very large. In this paper, the role and expectation of civil engineering, and the latest trend in the disposal techniques to need an argument to the order of very-long term of longer than 1,000 to 10,000 years which civil engineering have not experienced until now, are described.

However, economic evaluation is gradually gaining importance, and a trial implementation of the cost-effectiveness evaluation of drugs and medical devices has begun. Discussions on economic evaluation began in May 2012 within a newly established sub-committee of the Chuikyo, referred to as the "Special Committee on Cost Effectiveness." After four years of discussions, this committee determined that during the trial implementation, the results of the cost-effectiveness evaluation would be used for the re-pricing of drugs and medical devices at the end of fiscal year (FY) 2017. Chuikyo selected 13 products (7 drugs and 6 medical devices) as targets for this evaluation. These products will be evaluated until the end of FY 2017 based on the following process: manufacturers will submit the data of economic evaluation; the National Institute of Public Health will coordinate the review process; academic groups will perform the actual review of the submitted data, and the expert committee will appraise these data. This represents the first step to introducing cost-effectiveness analysis in the Japanese healthcare system. We believe that these efforts will contribute to the efficiency and sustainability of the Japanese healthcare system. Copyright © 2017 The Author(s). Published by Elsevier B.V. All rights reserved.

    We investigated radionuclides deposition and fine sediment transport in a 13 ha headwater watershed, Tochigi prefecture, located in 98.94 km north of Tokyo. The study site was within Karasawa experimental forest, Tokyo University of Agriculture and Technology. We conducted fingerprinting approach, based on the activities of fallout radionuclides, including caesium-134 (Cs-134) caesium-137 (Cs-137) and excess lead-210 (Pb-210ex). For indentifying specific sources of fine sediment, we sampled tree, soil on forested floor, soil on logging road surface, stream bed and stream banks. We investigated the radionuclides (i.e., as Cs-134, Cs-137 and Pb-210ex) deposition on tree after accident of nuclear power plants on March 11, 2011. We sampled fruits, leaves, branches, stems, barks on Japanese cedar (Sugi) and Japanese cypress (Hinoki). To analyze the samples, gammaray spectrometry was performed at a laboratory at the University of Tsukuba (Tsukuba City, Japan) using n-type coaxial low-energy HPGe gamma detectors (EGC-200-R and EGC25-195-R of EURYSIS Co., Lingolsheim, France) coupled with a multichannel analyzer. We also collected soil samples under the forest canopy in various soil depths from 2, 5, 10, 20, 30 cm along transect of hillslopes. Samples at forest road were collected road segments crossing on the middle section of monitoring watersheds. Fine sediment transport in the streams were collected at the outlet of 13 ha watersheds using integrated suspended sediment samplers. This study indicates the some portion of radio nuclide potentially remained on the tree surface. Part of the deposited radionuclides attached to soil particles and transported to the streams. Most of the fine sediment can be transported on road surface and/or near stream side (riparian zones).

Japan Chiebukuro”. Our aim was to clarify the characteristics related to people’s descriptions of suspected ADRs and determine the reasons for submitting a spontaneous inquiry. Methods: Fifty brand names of medicines used for inquiry extraction were chosen by selecting 35 pharmaceutical products, based on the generic names that had the highest sales in Japan. Questions containing both the brand name of one of these medicines and the term “Fukusayō” (ADR in Japanese that were posted from July 2004 to June 2009 were extracted from the site. Results: Among 1,419 questions extracted, 614 questions had at least one identifiable brand name of a suspected medicine, an ADR description, and the extent to which the ADR appeared to be caused by the suspected medicine(s. Among these 614 questions, 589 described in detail the symptoms/signs that the inquirers themselves or their families had experienced as ADRs. The highest number of questions was found for Paxil (525. Posts asking whether the symptoms being experienced were due to an ADR accounted for the highest number of questions. In most cases, the inquirer suspected that a single medicine led to an ADR and was seeking advice from others taking the same medicine. Conclusion: Our examination of spontaneous inquiries showed that people have sufficient knowledge to adequately report potential ADRs in terms of their symptoms

  12. Liquid hydrogen in Japan

    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 sarin gas attack in the Tokyo subway system is reviewed from a clinical toxicology perspective. Based on the lessons learned from this attack, the following areas should be addressed on a global scale. First, an adequate supply of protective equipment is required, including level B protective equipment with a pressure demand breathing apparatus. In addition, a system should be established that enables a possible cause to be determined based on symptoms, physical findings, general laboratory tests, and a simple qualitative analysis for poisonous substances. If an antidote is needed, the system should enable it to be administered to the victims as quickly as possible. Preparation for a large-scale chemical attack by terrorists requires the prior establishment of a detailed decontamination plan that utilizes not only mass decontamination facilities but also public facilities in the area. A system should be established for summarizing, evaluating, and disseminating information on poisonous substances. Finally, a large-scale scientific investigation of the Tokyo sarin attack should be conducted to examine its long-term and subclinical effects and the effects of exposure to asymptomatic low levels of sarin.

    The Great East Japan (Tōhoku/Kanto) earthquake of March 2011 was followed by a major tsunami and nuclear incident. Several previous studies have suggested a number of psychological responses to such disasters. However, few previous studies have modelled individual differences in the risk perceptions of major events, or the implications of these perceptions for relevant behaviours. We conducted a survey specifically examining responses to the Great Japan earthquake and nuclear incident, with data collected 11-13 weeks following these events. 844 young respondents completed a questionnaire in three regions of Japan; Miyagi (close to the earthquake and leaking nuclear plants), Tokyo/Chiba (approximately 220 km from the nuclear plants), and Western Japan (Yamaguchi and Nagasaki, some 1000 km from the plants). Results indicated significant regional differences in risk perception, with greater concern over earthquake risks in Tokyo than in Miyagi or Western Japan. Structural equation analyses showed that shared normative concerns about earthquake and nuclear risks, conservation values, lack of trust in governmental advice about the nuclear hazard, and poor personal control over the nuclear incident were positively correlated with perceived earthquake and nuclear risks. These risk perceptions further predicted specific outcomes (e.g. modifying homes, avoiding going outside, contemplating leaving Japan). The strength and significance of these pathways varied by region. Mental health and practical implications of these findings are discussed in the light of the continuing uncertainties in Japan following the March 2011 events.

    2008-12-01

    The medical schools in the beginning of Meiji era were diverse both in the founders and in the way of education, frequently employing foreign teachers of various nationalities. In 1871, German teachers were appointed to organized medical education at the medical school of the university of Tokyo. The anatomical education in the school was conducted by German teachers, i.e. Miller (1871-1873), Dönitz (1873-1877), Gierke (1877-1880) and Disse (1880-1885), followed by Koganei who returned from the study in Germany. In 1882 (Meiji 15th), the general rule for medical school was enforced so that the medical schools were practically obliged to employ numbers of graduates of the university of Tokyo. In 1887 (Meiji 20th), the educational system was reformed so that many of the medical schools were closed, and the medical schools were integrated into one university, five national senior high schools and three prefectural ones in addition to four private ones. After that most of anatomical teachers were either graduates of the university of Tokyo or those who studied in the anatomical department of the university. Before 1877 (Meiji 10th), the anatomical books were mainly translated from English books, and foreign teachers of various nationality were employed in many medical schools in Japan. After 1877 (Meiji 10th), the anatomical books based on the lectures by German teachers at the university of Tokyo were published. The anatomical books after 1887 (Meiji 20th) were written based on German books, and the German anatomical terms were utilized. After 1905 (Meiji 38th), the original Japanese anatomical books appeared, employing international anatomical terms. At the first meeting of Japanese Association of Anatomists in 1893 (Meiji 26th), the Japanese anatomical teachers met together and most of them were graduates of the university of Tokyo or fellows of its anatomical department.

    This special issue of Journal of Physics: Condensed Matter comprises selected papers from the 1st International Conference on Quantum Simulators and Design (QSD2006) held in Hiroshima, Japan, 3-6 December 2006. This conference was organized under the auspices of the Development of New Quantum Simulators and Quantum Design Grant-in-Aid for Scientific Research on Priority Areas, Ministry of Education, Culture, Sports, Science and Technology of Japan (MEXT), and Hiroshima University Quantum design is a computational approach to the development of new materials with specified properties and functionalities. The basic ingredient is the use of quantum simulations to design a material that meets a given specification of properties and functionalities. For this to be successful, the quantum simulation should be highly reliable and be applicable to systems of realistic size. A central interest is, therefore, the development of new methods of quantum simulation and quantum design. This includes methods beyond the local density approximation of density functional theory (LDA), order-N methods, methods dealing with excitations and reactions, and so on, as well as the application of these methods to the design of new materials and devices. The field of quantum design has developed rapidly in the past few years and this conference provides an international forum for experimental and theoretical researchers to exchange ideas. A total of 183 delegates from 8 countries participated in the conference. There were 18 invited talks, 16 oral presentations and 100 posters. There were many new ideas and we foresee dramatic progress in the coming years. The 2nd International Conference on Quantum Simulators and Design will be held in Tokyo, Japan, 31 May-3 June 2008.

    Current Japanese State System for Accountancy and Control (SSAC) has been developing and fully satisfies requirements of both IAEA Safeguards and bilateral partners. However, the public attention on the national and international safeguards activities were increased and the safeguards authorities were required to promote the objective assessment of safeguards implementation to avoid mistrust in safeguards activities which directly influence the public acceptance of nuclear energy in itself. Additionally, since Japan has promoted to complete nuclear fuel cycle including spent fuel reprocessing, enrichment and mixed oxide fuel fabrication this would require further assurance of Japanese non-proliferation commitment. Japan supports the introduction of strengthened safeguards. In this context it is particularly important to strengthen the relationship between national and the IAEA safeguards to contribute actively to the IAEA safeguards in development and utilization of new technologies towards more effective and efficient IAEA safeguards

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

    Full Text Available The paper looks at how Japan, one of the major donors of African countries, has been redefining its positions on the African continent in terms of bilateral aid and business opportunities, triangular collaboration and multilateral development projects in an increasingly ‘interpolar’ world of international relations. The discussion includes China's expanding presence all over Africa as an important ‘reference point’ for the Japanese public at large and how that may influence Japanese pragmatic foreign policy towards the continent and Japan's involvement in African development. What are Japan's priorities in the wake of hosting the fifth Tokyo International Conference on African Development (TICAD V early in June 2013 in Yokohama? How does Japan go along with its confident manner of inclusive development and ownership in African societies when at the same time it is challenged by China and other emerging actors? What are the items on Japan's agenda for a re-intensified Africa policy?

    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.

    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.

    This study was conducted to determine the prevalence of Listeria monocytogenes in retailed meats, comprising beef, chicken, and pork, in the Tokyo metropolitan area. A total of 379 samples of retailed meat were collected from 1998 to 2003, most of which were obtained by simultaneously purchasing the three classes of meat from a shop and then making another simultaneous purchase of meat from the same shop a few weeks later. The prevalence of L. monocytogenes was 28.0%, and the serotypes isolated were mainly 1/2a, 1/2b, 1/2c, and 4b. Comparison of the prevalence of each serotype among the classes of meat showed a predominant distribution of serotypes 1/2a, 1/2b, and 4b in chicken, while serotype 1/2c was dominant in pork. A total of nine cases considered to be due to persistence and/or cross-contamination were found. Most of the strains involved in persistence and/or cross-contamination were of serotypes 1/2c or 4b. These results suggest that contamination in retailed meat in Japan is at almost the same level as in other countries and that chicken has the highest potential as a source of contamination and infection. In addition, we suggest that the ecological niche of serotype 1/2c is distinct from those of 1/2a, 1/2b, and 4b, which may explain why human hosts have less opportunity to be exposed to serotype 1/2c and why there is a lower rate of isolation of this serotype from cases of human listeriosis.

    Background The number of welfare recipients has steadily increased in Japan during recent years, although the number of homeless persons has decreased. Despite there being many reports regarding medicolegal death among homeless persons, medicolegal death among welfare recipients has not been fully investigated. Methods We identified 10,293 individuals who received welfare aid during their lifetime among the 81,867 cases that were examined by the Tokyo Medical Examiner's Office (2008-2013). We retrospectively compared the proportions of medicolegal death to total population, age, sex, family status, clinical history, and manners/causes of death among non-indigent persons (controls), homeless persons, and welfare recipients. Results A higher proportion of medicolegal death to total population was observed among the welfare recipients, compared with the controls. The welfare recipients (65.5 years) were younger than the controls (68.9 years), and the proportions of male sex and living alone were higher among the welfare recipients. Hypertension and circulatory disease were the leading clinical conditions among the welfare recipients. Death due to disease was the leading manner of death, and circulatory disease was the leading cause of death among the welfare recipients. The proportion of individuals with a long period between death and discovery (which made determining the cause of death difficult) was also higher among the welfare recipients. Conclusion Welfare recipients have a greater risk of sudden death compared with non-indigent persons. Preventive strategies should target middle-aged to elderly men who live alone, and should address their risks of circulatory diseases and solitary death.

    Recently, the number of homeless persons in Japan has steadily decreased. However, it is not certain whether unexpected death of the homeless have actually decreased in proportion to decrease in total number of cases. The documentation of medicolegal deaths among homeless persons handled in the Tokyo Medical Examiner's Office during 1999-2010 were reviewed, and we compared the number and manner/cause of death between cases occurring before 2004 and those occurring after 2004. In addition, we compared manner/cause of death between homeless and non-homeless persons. The number of medicolegal deaths of homeless persons remained almost the same during the study period in spite of a marked decrease in the total number of homeless persons after 2004. Age distribution shifted to older after 2004, and a higher proportion of the deceased had longer postmortem periods after 2004. Comparison between the manners/causes of death of the cases occurring before 2004 and those occurring after 2004 showed little difference. Disease constituted about 70% of all cases, and causes of death from disease were more various than those of non-homeless persons. Certain specific patterns included a higher proportion of death from circulatory disease in elderly homeless persons and a higher proportion of death from alcohol-related digestive disease and tuberculosis among younger homeless persons. Regarding accidental death, hypothermia was a leading cause of death irrespective of age group. Aging and isolation among homeless persons might contribute to an unchanged number of medicolegal death of them. In addition to measures to address frequent causes of death in each age group, better intervention for isolated homeless persons might be a key factor to prevent unexpected deaths of homeless persons in the future.

    In accelerator mass spectrometry (AMS), the sample to be analyzed itself is accelerated to form ion beams, and mass spectrometry is applied. Particularly with AMS, a very small amount of long half-life radioactive isotope can be measured with extremely high sensitivity. As the example of AMS measurement, this study firstly took up the measurement of 14 C, which is the most widely used as a probe for dating, as well as the measurement of 10 Be and 26 Al as examples. Then, it described the outline of AMS measurement using a tandem type electrostatic accelerator, which has many advantageous features for AMS. Today, tandem type electrostatic accelerator is used in AMS measurement in most cases. Finally, this paper reviewed the macro analysis laboratory tandem (MALT) accelerator of the Atomic Energy Research Center, University of Tokyo. The accelerator is pelletron type and acceleration voltage is maximum 5 MV. It is No. 1 unit that the USA NEC Corporation designed with consciousness of AMS. The incident analysis system is equipped with a sequential injection system that allows ions of different masses to be injected alternately, and the analysis system on the high energy side is equipped with a multi-Faraday cup system. At MALT, in addition to 14 C - AMS, routine measurements of 10 Be - AMS, 26 Al - AMS that are unique in Japan are carried out. In addition, MALT has multiple beam courses, and conducts the ultrafine analysis of elements using the methods other than AMS, as well as accelerator analysis research such as basic scientific experiments.

    Cities mingle with rugged hills and a dormant volcano in this image of Hokkaido, Japan. This three-dimensional image comes from observations made by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite on July 23, 2006. The view is toward the north and slightly east. Green indicates vegetation; beige and gray indicate bare ground, paved surfaces, or buildings; and dark blue indicates water. The water body at the top of the image is the Pacific Ocean. Now dormant, Mount Yotei is a stratovolcano--a symmetrical cone composed of alternating layers of hardened lava, solidified ash, and volcanic rocks ejected in previous eruptions. It reaches a height of 1,898 meters (6,227 feet), and its summit sports a 700-meter- (2,297-foot-) wide crater. Snow often caps this volcano, but in this summertime shot, the volcano's summit is snow-free. The volcano is also known as Ezo-Fuji for its resemblance to Mount Fuji. As angular patches of gray and beige indicate, urban areas surround the volcano, most notably the city of Kutchan to the northwest. Even when volcanoes remain active, people often settle close to them, drawn by benefits of good soil and mild climates that appear to outweigh the risks.

    Amid the effects of global warming, Tokyo has become an increasingly hot city, especially during the summertime. To prepare for the upcoming 2020 Summer Olympics and Paralympics in Tokyo, all participants, including the athletes, staff, and spectators, will need to familiarize themselves with Tokyo's hot and humid summer conditions. This paper uses the wet-bulb globe temperature (WBGT) index, which estimates the risk of heat illness, to compare climate conditions of sports events in Tokyo with the conditions of the past three Summer Olympics (held in Rio de Janeiro, London, and Beijing) and to subsequently detail the need for establishing appropriate countermeasures. We compared WBGT results from the past three Summer Olympics with the same time periods in Tokyo during 2016. There was almost no time zone where a low risk of heat illness could be expected during the time frame of the upcoming 2020 Tokyo Olympics. We also found that Tokyo had a higher WBGT than any of those previous host cities and is poorly suited for outdoor sporting events. Combined efforts by the official organizers, government, various related organizations, and the participants will be necessary to deal with these challenging conditions and to allow athletes to perform their best, as well as to prevent heat illnesses among staff and spectators. The sporting committees, as well as the Olympic organizing committee, should consider WBGT measurements in determining the venues and timing of the events to better avoid heat illness and facilitate maximum athletic performance.

    The monitoring of absorbed dose rate in air has been carried out continually at various locations in metropolitan Tokyo after the accident of the Fukushima Daiichi Nuclear Power Plant. While the data obtained before the accident are needed to more accurately assess the effects of radionuclide contamination from the accident, detailed data for metropolitan Tokyo obtained before the accident have not been reported. A car-borne survey of the absorbed dose rate in air in metropolitan Tokyo was carried out during August to September 2003. The average absorbed dose rate in air in metropolitan Tokyo was 49±6 nGy h(-1). The absorbed dose rate in air in western Tokyo was higher compared with that in central Tokyo. Here, if the absorbed dose rate indoors in Tokyo is equivalent to that outdoors, the annual effective dose would be calculated as 0.32 mSv y(-1). © The Author 2015.

    This study is the first ever field survey in Japan of the prevalence of psychiatric disorders among homeless people in one area of Tokyo. The main aim of was to make accurate diagnoses by a psychiatrist to give an accurate picture. The survey period was from December 30, 2008 to January 4, 2009. The people covered by the survey were people living on the streets within a one-kilometer radius ofJR Ikebukuro Station in this period. The survey area was selected within Toshima City as a district where it would be possible to roughly grasp the total number of homeless people. The definition of homeless people in this study was the same as that which was stipulated in the Ministry of Health, Labor and Welfare national survey. A total of 115 people living on the streets received the written request to participate in the survey and 80 agreed to do so, beiung enrolled as the subjects of this study. Mini International Neuropsychiatric Interview (MINI) questionnaires and a separately created questionnaire that asked about the subjects' living circumstances were used in the interviews and finally, a psychiatrist made diagnoses of psychiatric disorders according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) diagnosis standards. The average age of the subjects was 50.5 (standard deviation; 12.3) and there were 75 men (93.8%) and 5 women (6.3%). 50 people (62.5%) were diagnosed with psychiatric disorders which included 33 people (41.3%) who had depression, 12 (15%) who were dependent on alcohol and 12 (15%) who had psychotic disorders such as hallucinations or delusions. Using the degree of risk in the MINI classification, 45 (57.0%) were at risk of committing suicide and 25 people (31.6%) had already attempted suicide in the past. The representativeness of homeless people in Japan who have psychiatric disorders in this study is limited but that the finding of 62.5% of homeless people suffering from some symptoms and a high

    Modern Van de Graaff accelerator was first built at Wisconsin University in 1934. After the World War II, High Voltage Engineering Corp. (HVEC) was established and manufactured many Van de Graaff accelerators. The HVEC succeeded in fabricating a Van de Graaff accelerator of tandem type, by which the proton bean with an energy of 20 MeV became available. In 1965 Pelletron was put into practical use. In Japan, development of Van de Graaff accelerator was initiated in 1940's at IPCR, the University of Tokyo, Osaka University, Kyoto University and Kyushu University. After the War, many Van de Graaff accelerators have been supplied mainly from industries. Physicists at Kyushu University developed the accelerator by their own way. (K.Y.)

    On December 21, 2001, at a hospital in Tokyo, an engineer setting a medical-linac was over-exposed by the equipment due to lack of communication between workers. The exposed dose was initially reported as 1000 mSv (1 Sv), but later revised to 200 mSv at most. The outline of the accident and the statistical data on radiation exposure accidents in Japan and the world are briefly overlooked. (author)

    Japan might be one of the most active countries dedicating themselves to studying the greenhouse gas (GHG) measurements using optical remote sensing not only on the ground but also from space. There are two reasons; one of them ascends to the Kyoto Protocol, agreed in December 1997 in Kyoto, an ancient city of Japan until 19th centuries, was designed to address the international response to serious climate change due to greenhouse gases. The other reason is due to a revision of the Basic Environment Law of Japan in order to meet the Kyoto Protocol in 1998. The State makes efforts to ensure international collaboration so as to effectively promote the monitoring, observation and measurement of the environmental situation with regard to global warming. Main activities are listed in a Table1. They are divided into two categories, i.e. the Greenhouse gases Observing SATellite (GOSAT), launched on Jan.23, 2009 and active remote sensing using lidar technology. In case of GOSAT, an initial analysis of carbon dioxide and methane concentrations was obtained for clear-sky scenes over land. In the future, after further calibration and validation of the data, observation data and corresponding analyzed products will be made available. On the other hand, studies of the laser remote sensing for measuring GHG have been actively carrying out to achieve reliable data with a higher accuracy at wavelengths of 1.6micron meter (Tokyo Metropolitan University, JAXA, Mitsubishi Electric Co.) and 2 micron meter (National Institute of Information and Communications Technology). As well-known, one of the most interests regarding atmospheric CO2 measurements is that carbon dioxide molecule measured are due to anthropological emission from fossil fuel burning or due to natural one from forest fires etc. We proposed a newly advanced CO2/CO DIAL using a hybrid of pulsed Tm,Ho:YLF and pulsed OPO pumped by it for better understanding them. Now, our effort is directed to find out the most suitable

    This paper overviews the technological development in FY2014 at Tokyo Electric Power Company, Chubu Electric Power Company, Hokuriku Electric Power Company, Shikoku Electric Power Company, and Electric Power Development Company. In this overview, further breakdown was made for the following departments of each company: nuclear power generation, thermal power generation, hydraulic power generation, power transmission, power distribution, transformation, research and development and technological development, and information and communication. In addition, this paper outlines the achievement of technological development at Japan Atomic Power Company, such as the technological development related to the existing power station, development of new technology, and the development of future reactor. Fukushima Daiichi Nuclear Power Station has developed an investigative system using a high altitude survey robot and a movable monitoring system. Hamaoka Nuclear Power Station examined the feasibility of state diagnostic technique based on multi-point analysis, and studied stress corrosion cracking at the newly established Nuclear Safety Research Laboratory. Shika Nuclear Power Station (Unit 1) applied a pipe stress improvement process by means of high frequency induction heating as a stress corrosion cracking countermeasure. Ikata Nuclear Power Station newly adopted high degree cross-linking cation resin, and high cracking strength anion resin as the primary resins. Oma Nuclear Power Station worked on the all reactor core utilization technology of MOX fuel. (A.O.)
