Changes in freshwater ecosystems due to a climate change have been great concern for sustainable river basin management both for water resources utilization and ecological conservation. However, their impact seems to be difficult to evaluate because of wide variety of basin characteristics along a river network both in nature and social environment. This presentation uses equilibrium water temperature as a simple criterion index for evaluating the long-term changes of stream thermal environment due to the historical climate change in Japan. It examines, at first, the relationship between the equilibrium water temperature and the stream temperature observed for 7 years at a lower reach in the Ibo River, Japan. It analyzes, then, the seasonal and regional trends of the equilibrium water temperature change for the last 50 years at 133 meteorological station sites throughout Japan, discussing their rising or falling characteristics. The correlation analysis at the local reach of the Ibo River shows that the equilibrium water temperature has similar trend of change as the stream temperature. However, its value tends to be higher than the stream temperature in summer, while lower in winter. The onset of the higher equilibrium water temperature fluctuates annually from mid February to early April. This onset fluctuation at each spring could be influenced by the different amount of snow at the antecedent winter. The rising or falling trends of the equilibrium water temperature are analyzed both annually and seasonally through the regression analysis of the 133 sites in Japan. Consequently, the trends of the temperature change could be categorized by 12 patterns. As for the seasonal analysis, the results shows that there are many sites indicating the falling trend in spring and summer, and rising trends in autumn and winter. In particular, winter has the strong rising tendency throughout Japan. As for the regional analysis, the result illustrates the precise rationality; e

This paper reports tritium levels in environmental waters in the China in comparison with those in Japan. Environmental water samples were collected in October-November 1987 from the drainage basin of Changjiang from Sichuan through Hubei districts. Tritium levels were 0.22 Bq/l-6.73 Bq/l (an average, 3.09{plus minus}1.18 Bq/l) in 50 ground water samples; 3.40 Bq/l-3.81 Bq/l (an average, 3.71{plus minus}0.81 Bq/l) in four river samples collected from the main course of the Changjiang River; 1.74 Bq/l-5.40 Bq/l (an average, 3.14{plus minus}1.52 Bq/l) in four river samples collected from the tributary river; and 0.63 Bq/l and 1.78 Bq/l in precipitation samples. Environmental waters contained a large quantity of Ca{sup 2+} and Mg{sup 2+} ions, irrespective of river and ground water samples. In comparing tritium levels in environmental waters in the China and Japan, tritium levels were higher in the ground water influenced by a landslide in the China than Japan. Tritium levels in precipitations collected from the drainage basin of the Changjiang were similar to those in Niigata (Japan), 0.63{plus minus}0.26 Bq/l and 1.78{plus minus}0.26 Bq/l vs 0.53{plus minus}0.36 Bq/l - 2.17{plus minus}0.40 Bq/l. The concentrations of Ca{sup 2+}, Mg{sup 2+}, and HCO{sub 3}{sup -} were higher in the Changjiang River (4 water samples) than the river waters, including the Shinano River in Japan. The concentrations of Na{sup +} and Cl{sup -} were higher in the Changjiang River than the average concentrations in the Japanese rivers, but lower than the Shinano River (Japan). A small quantity of precipitations and width of the Changjiang River, as well as nuclear explosion test performed up to 1980, seem to influence higher tritium levels in the Changjiang than those in Japan.

This study was initiated to examine if variations in the concentrations of cadmium (Cd) and lead (Pb) in water environment may affect metal levels in local foods and body burden of local residents in non-polluted areas in Japan. Two nationwide databases have been made available on concentrations of Cd in locally harvested brown rice and of Cd and Pb in sediments in local river beds. These data were combined with published data on metal concentrations in polished rice, food duplicates, and blood and urine from the residents. Cd in river sediments correlated significantly with those in brown rice, food duplicates, blood, and urine. Cd in food duplicates correlated with Cd in rice. In contrast, Pb concentrations in the river sediments either did not correlate or correlated only weakly with Pb in biological materials or food duplicates. Possible implication of the different behavior between Cd and Pb regarding the intensity of correlation was discussed with reference to the different routes of exposure to the elements. In conclusions, the Cd body burden on local residents in Japan is significantly influenced by Cd levels in water in the general environment, whereas water-borne Pb did not show clear correlation with the Pb body burden.

Cyprinid herpesvirus 3 (CyHV-3) disease is a significant threat for common and koi carp cultivators and for freshwater ecosystems. To determine the prevalence of CyHV-3 in Japanese rivers, a nationwide survey of all national class-A rivers was undertaken in the Summer of 2008. The virus was concentrated from river water samples using the cation-coated filter method. CyHV-3 DNA was detected in 90 rivers, representing 90% of 103 successfully analysed rivers. More than 100,000 copies of CyHV-3 DNA per litre of sample were detected in four rivers, higher than that reported during the Yura River outbreak in 2007. For CyHV-3-positive rivers, the log CyHV-3 density was negatively correlated with the water temperature on the sampling date and positively correlated with the suspended solids and dissolved oxygen, which are annually averaged for each river. Our results demonstrate that virus detection using molecular biology techniques is a powerful tool for monitoring the presence of CyHV-3 in natural environments. Copyright © 2011 Elsevier Ltd.

As a competition event of the 2016 Olympic Game, golf sport has aroused great attention around the world. And the Yangtze River Delta(YRD) in China, has already got certain basis and qualifications of developing golf industry, but somehow far from meeting the great potential demand of the market. This research selects the Yangtze River Delta (YRD) and Central Japan (CJ), which are indifferent golf developing stages, as the objectives. Comparative studies are being carried out with an aim of revealing the discrepancies of golf industry in selected regions. The correlations between golf industry and regional economic developing level have been explored as well. Mainly based on a geographical perspective, this research presents an initial effort to combine approaches of setting comparative indexes and spatial analysis, so that golf industry of selected regions will be compared in all directions. The results reveal that great gaps exist in YRD and CJ in terms of golf construction, service, and golf consumption. Problems in developing golf industry in YRD are identified based on the empirical results. A long-term golf development in YRD that deviating from the realistic demand is attributed to both government policies and the operational principles that the market subjects hold. Based on a comparative empirical study, suggestions relating to the government as well as the market players are put forward, with an aim of guiding the golf industry to develop in a sustainable way.

Water, sediment, and large wood (LW) are the three key components of dynamic river-floodplain ecosystems. We examined variations in sediment and LW discharge with respect to precipitation, the presence of dams, land and river use change, and related channel incision and forest expansion on gravel bars and floodplains across Japan. The results indicated that unit sediment discharge and unit LW discharge were smaller in southern Japan where precipitation intensity is generally much greater. Effective precipitation, an index that takes current and antecedent precipitation into account, was a strong predictor of discharge in small watersheds, but not in larger watersheds. However, precipitation intensities related to unit sediment discharge in intermediate and large watersheds were smaller than those associated with unit LW discharge, which we attribute to differences in particle shape and size and also transport mechanisms. The relationship between river flow and discharge of sediment and LW lead us to posit that discharges of these components are supply limited in southern Japan and transport limited in northern Japan. The cross-sectional mean low-flow bed elevation of gravel-bed and sand-bed rivers in Japan decreased by 0.71 and 0.74 m on average, respectively, over the period 1960-2000. Forest expansion on bars and floodplains has been prominent since the 1990s, and trees apparently began to colonize gravel bars 10 to 20 years after riverbed degradation began. Forest recovery in headwater basins, dam construction, gravel mining, and channelization over the past half century are likely the dominant factors that significantly reduced downstream sediment delivery, thereby promoting channel incision and forest expansion. Changes in rivers and floodplains associated with channel incision and forest expansion alter the assemblages of aquatic and terrestrial organisms in riverine landscapes of Japan, and climate change may contribute to this change by intensified

Freshwater biodiversity has been severely threatened in recent years, and to conserve endangered species, their distribution and breeding habitats need to be clarified. However, identifying breeding sites in a large area is generally difficult. Here, by combining the emerging environmental DNA (eDNA) analysis with subsequent traditional collection surveys, we successfully identified a breeding habitat for the critically endangered freshwater fish Acheilognathus typus in the mainstream of Omono River in Akita Prefecture, Japan, which is one of the original habitats of this species. Based on DNA cytochrome B sequences of A. typus and closely related species, we developed species-specific primers and a probe that were used in real-time PCR for detecting A. typus eDNA. After verifying the specificity and applicability of the primers and probe on water samples from known artificial habitats, eDNA analysis was applied to water samples collected at 99 sites along Omono River. Two of the samples were positive for A. typus eDNA, and thus, small fixed nets and bottle traps were set out to capture adult fish and verify egg deposition in bivalves (the preferred breeding substrate for A. typus) in the corresponding regions. Mature female and male individuals and bivalves containing laid eggs were collected at one of the eDNA-positive sites. This was the first record of adult A. typus in Omono River in 11 years. This study highlights the value of eDNA analysis to guide conventional monitoring surveys and shows that combining both methods can provide important information on breeding sites that is essential for species' conservation.

Land cover changes around river basins have caused serious environmental degradation in global surface water areas, in which the direct monitoring and numerical modeling is inherently difficult. Prediction of pollutant loads is therefore crucial to river environmental management under the impact of climate change and intensified human activities. This research analyzed the relationship between land cover types estimated from NOAA Advanced Very High Resolution Radiometer (AVHRR) imagery and the potential annual pollutant loads of river basins in Japan. Then an empirical approach, which estimates annual pollutant loads directly from satellite imagery and hydrological data, was investigated. Six water quality indicators were examined, including total nitrogen (TN), total phosphorus (TP), suspended sediment (SS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Dissolved Oxygen (DO). The pollutant loads of TN, TP, SS, BOD, COD, and DO were then estimated for 30 river basins in Japan. Results show that the proposed simulation technique can be used to predict the pollutant loads of river basins in Japan. These results may be useful in establishing total maximum annual pollutant loads and developing best management strategies for surface water pollution at river basin scale.

Sediment denitrification rate and its role in removal of dissolved nitrate load in lower Ishikari river system were examined. Denitrification rate were measured using acetylene inhibition technique on the sediment samples collected during August 2009-July 2010. The denitrification rate varied from 0.001 to 1.9 μg Ng(-1) DM h(-1) with an average value of 0.21 μg Ng(-1) DM h(-1) in lower Ishikari river system. Denitrification rate showed positive correlation with dissolved nitrate concentration in the river basin, indicating overlying water column supplied nitrate for the sediment denitrification processes. Nutrient enrichment experiments result showed that denitrification rate increased significantly with addition of nitrate in case of samples collected from Barato Lake however no such increase was observed in the samples collected from Ishikari river main channel and its major tributaries indicating that factors other than substrate concentration such as population of denitrifier and hydrological properties of stream channel including channel depth and flow velocity may affects the denitrification rate in lower Ishikari river system. Denitrification rate showed no significant increase with the addition of labile carbon (glucose), indicating that sediment samples had sufficient organic matter to sustain denitrification activity. The result of nutrient spiraling model indicates that in- stream denitrification process removes on an average 5%d(-1) of dissolve nitrate load in Ishikari river. This study was carried out to fill the gap present in the availability of riverine denitrification rate measurement and its role in nitrogen budget from Japanese rivers characterize by small river length and high flow rate.

A study was conducted on the pesticides Diuron, Irgarol 1051 and Fenitrothion in Kurose River water, Higashi Hiroshima, Japan for a period of one year to assess the contribution of agriculture and urban activities on pesticide pollution of the river. Samples were analysed by a reverse phase HPLC system. The maximum pesticide concentrations were; 4620 ng/L, 50 ng/L and 370 ng/L for Diuron, Irgarol 1051 and Fenitrothion, respectively. While Diuron and Fenitrothion were detected at all sites, Irgarol 1051 was only present at Izumi, a high density urban and industrial area which also registered the highest concentrations of the pesticides. The pattern showed by Diuron and Fenitrothion was linked to farming activities. Also, Diuron and Fenitrothion concentration correlated with pesticide utilization data for Hiroshima Prefecture. Irgarol 1051 showed a different pattern to that of Diuron and Fenitrothion and its source was attributed to paint. It was noted that 78% and 42% of water samples at Izumi sampling site exceeded the European Union (EU) guidelines for Diuron and Fenitrothion, respectively. Copyright © 2015 Elsevier B.V.

We satellite-tracked Whooper Swans Cygnus cygnus wintering in northern Japan to document their migration routes and timing, and to identify breeding areas. From 47 swans that we marked at Lake Izunuma-Uchinuma, Miyagi Prefecture, northeast Honshu, and at Lake Kussharo, east Hokkaido, we observed 57 spring and 33 autumn migrations from 2009-2012. In spring, swans migrated north along Sakhalin Island from eastern Hokkaido using stopovers in Sakhalin, at the mouth of the Amur River and in northern coastal areas of the Sea of Okhotsk. They ultimately reached molting/breedmg areas along the Indigirka River and the lower Kolyma River in northern Russia. In autumn, the swans basically reversed the spring migration routes. We identified northern Honshu, eastern Hokkaido, coastal areas in Sakhalin, the lower Amur River and northern coastal areas of the Sea of Okhotsk as the most frequent stopover sites, and the middle reaches of the Indigirka and the lower Kolyma River as presumed breeding sites. Our results are helpful in understanding the distribution of the breeding and stopover sites of Whooper Swans wintering in Japan and in identifying their major migration habitats. Our findings contribute to understanding the potential transmission process of avian influenza viruses potentially carried by swans, and provide information necessary to conserve Whooper Swans in East Asia.

Erosional and sedimentary features associated with flooding have been documented in both modern and past cases. However, only a few studies have demonstrated the relationship between these features and the corresponding hydraulic conditions that produced them, making it difficult to evaluate the magnitude of paleo-flooding. This study describes the characteristics associated with inundation depth and flow direction, as well as the erosional and sedimentary features resulting from the disastrous flooding of the Kinu River, central Japan, in September 2015. Water levels rose rapidly due to heavy rainfall that eventually overtopped, and subsequently breached, a levee in Joso City, causing destructive flooding on the surrounding floodplain. Distinctive erosional features are found next to the breached levee, while depositional features, such as a sandy crevasse-splay deposit are found further away from the breach. The deposit can be divided into three units based on sedimentary facies. The vertical and lateral changes of these sedimentary facies may be the result of temporal and spatial changes associated with flow during the single flooding event. These observations and quantitative data provide information that can be used to reveal the paleohydrology of flood deposits in the stratigraphic record, leading to improved mitigation of future flooding disasters.

Full Text Available After 26 years, we followed up 7348 participants in a 1979–1984 health screening survey in the Jinzu River basin, the heaviest cadmium-polluted area in Japan. We assessed the associations of cadmium exposure levels and mortality from cancer and renal damage, indicated by records of proteinuria and glucosuria in the original survey. Mortality risks (hazard ratios were analyzed using the Cox proportional hazards model, stratified by sex, after adjusting for age, smoking status, and hypertension, as indicated in the original survey records. In men, the adjusted hazard ratio for mortality from lung cancer was significantly lower in individuals residing in an area of historically high cadmium exposure and in subjects with a historical record of proteinuria, glucosuria, and glucoproteinuria. The risk of mortality from prostate cancer was borderline higher in cadmium-exposed men. In women, historical cadmium exposure was not associated with an increased risk of mortality from malignant neoplasms, but the adjusted hazard ratios for death from total malignant neoplasms or from renal and uterine cancers were significantly higher in exposed subjects with a historical record of proteinuria, glucosuria, and glucoproteinuria. These findings suggest that women residing in cadmium-polluted areas who exhibit markers of renal damage may be at risk of dying of cancer.

A nationwide survey of N-nitrosodimethylamine (NDMA) in both raw and finished water samples from drinking water treatment plants (DWTPs) in Japan was conducted. NDMA was analyzed by solid-phase extraction (SPE) followed by ultra performance liquid chromatography (UPLC) coupled with tandem mass spectrometry (MS/MS). NDMA was detected in 15 of 31 raw water samples collected in the summer at concentrations up to 2.6 ng/L, and in 9 of 28 raw water samples collected in winter at concentrations up to 4.3 ng/L. The NDMA concentrations were higher in raw water samples collected from treatment plants with catchment areas that have high population densities. The NDMA concentrations were higher in river water samples collected from the east and west of Japan than in those collected from other areas. NDMA was detected in 10 of 31 finished samples collected in summer at reduced concentrations of up to 2.2 ng/L, while 5 of 28 finished samples collected in winter showed NDMA concentrations up to 10 ng/L. The highest NDMA levels were detected in finished water samples collected from the Yodo River basin DWTP, which uses ozonation. Furthermore, evaluation of the process water produced at six advanced water treatment plants was conducted. Influent from the Yodo River indicated that the NDMA concentration increased during ozonation to as high as 20 ng/L, and then decreased with subsequent biological activated carbon treatment. To our knowledge, this is the first nationwide evaluation of NDMA concentrations in water conducted in Japan to date.

We estimated the effects of extreme fluvial outflow events from river mouths on the salinity distribution in the Japanese coastal zones. Targeted extreme event was a typhoon from 06/09/2015 to 12/09/2015, and we generated a set of hourly simulated river outflow data of all Japanese first-class rivers from these basins to the Pacific Ocean and the Sea of Japan during the period by using our model "Cell Distributed Runoff Model Version 3.1.1 (CDRMV3.1.1)". The model simulated fresh water discharges for the case of the typhoon passage over Japan. We used these data with a coupled hydrological-oceanographic model JCOPE-T, developed by Japan Agency for Marine-earth Science and Technology (JAMSTEC), for estimation of the circulation and salinity distribution in Japanese coastal zones. By using the model, the coastal oceanic circulation was reproduced adequately, which was verified by satellite remote sensing. In addition to this, we have successfully optimized 5 parameters, soil roughness coefficient, river roughness coefficient, effective porosity, saturated hydraulic conductivity, and effective rainfall by using Shuffled Complex Evolution method developed by University of Arizona (SCE-UA method), that is one of the optimization method for hydrological model. Increasing accuracy of peak discharge prediction of extreme typhoon events on river mouths is essential for continental-oceanic mutual interaction.

Japan, with its natural mountainous landscape, has demographic feature that population is concentrated in lower reach of elevation close to the coast, and therefore flood damage with large socio-economic value tends to occur in low-lying region. Modeling of river flood in such low-lying urbanized river basin is complex due to the following reasons. In upstream it has been experienced urbanization, which changed land covers from natural forest or agricultural fields to residential or industrial area. Hence rate of infiltration and runoff are quite different from natural hydrological settings. In downstream, paved covers and construct of sewerage system in urbanized areas affect direct discharges and it enhances higher and faster flood peak arrival. Also tidal effect from river mouth strongly affects water levels in rivers, which must be taken into account. We develop an integrated river flood model in lower reach of urbanized areas to be able to address above described complex feature, by integrating model components: LSM coupled distributed hydrological model that models anthropogenic influence on river discharges to downstream; urban hydrological model that simulates run off response in urbanized areas; Saint Venant's equation approximated river model that integrates upstream and urban hydrological models with considering tidal effect from downstream. These features are integrated in a common modeling framework so that model interaction can be directly performed. The model is applied to the Tsurumi river basin, urbanized low-lying river basin in Yokohama and model results show that it can simulate water levels in rivers with acceptable model errors. Furthermore the model is able to install miscellaneous water planning constructs, such as runoff reduction pond in urbanized area, flood control field along the river channel, levee, etc. This can be a useful tool to investigate cost performance of hypothetical water management plan against impact of climate change in

The expected geomorphic after-effects of the M{sub w} 9.0 Tōhoku-oki earthquake of 11 March 2011 (eastern Japan) are summarized by a schematic model of seismic driving, which details seismogenic disturbances to sediment systems that affect the rate or timing of sediment delivery to coastlines over timescales of 10{sup 2}–10{sup 4} years. The immediate physical environmental responses to this high-magnitude earthquake included a large tsunami and extensive region-wide slope failures. Normally, slope failures within mountain catchments would have significant impacts on Japan's river and coastal geomorphology in the coming decades with, for example, a new beach ridge expected to form within 20–100 years on the Sendai Plain. However, human activity has significantly modified the rate and timing of geomorphic processes of the region, which will have impacts on likely geomorphic responses to seismic driving. For example, the rivers draining into Sendai Bay have been dammed, providing sediment traps that will efficiently capture bedload and much suspended sediment in transit through the river system. Instead of the expected ~ 1 km of coastal progradation and formation of a ~ 3 m high beach ridge prior to the next large tsunami, it is likely that progradation of the Sendai Plain will continue to slow or even cease as a result of damming of river systems and capture of river sediments behind dams. The resulting reduction of fluvial sediment delivery to the coast due to modification of rivers inadvertently makes seawalls and other engineered coastal structures even more necessary than they would be otherwise. - Highlights: • The Tōhoku-oki earthquake led to seismogenic landslides inland. • Seismogenic sediments are reworked through river systems to the coast. • River dams are capturing these sediments, reducing sediment supply to the coast. • Reduced coastal sediment supply is increasing tsunami risk. • Engineering of river systems is making coastal

However, human activity has significantly modified the rate and timing of geomorphic processes of the region, which will have impacts on likely geomorphic responses to seismic driving. For example, the rivers draining into Sendai Bay have been dammed, providing sediment traps that will efficiently capture bedload and much suspended sediment in transit through the river system. Instead of the expected ~ 1 km of coastal progradation and formation of a ~ 3 m high beach ridge prior to the next large tsunami, it is likely that progradation of the Sendai Plain will continue to slow or even cease as a result of damming of river systems and capture of river sediments behind dams.

The expected geomorphic after-effects of the Mw 9.0 Tōhoku-oki earthquake of 11 March 2011 (eastern Japan) are summarized by a schematic model of seismic driving, which details seismogenic disturbances to sediment systems that affect the rate or timing of sediment delivery to coastlines over timescales of 10(2)-10(4)years. The immediate physical environmental responses to this high-magnitude earthquake included a large tsunami and extensive region-wide slope failures.

Negligible contribution of reservoir dams to organic and inorganic transport in the lower Mimi River, Japan

Rivers fulfill an essential ecological role by forming networks for material transport from upland forests to coastal areas. The way in which dams affect the organic and inorganic cycles in such systems is not well understood. Herein, we investigated the longitudinal profiles of the various components of the water chemistry across three cascade dams in Japan: the Yamasubaru Dam, Saigou Dam, and Ohuchibaru Dam, which are situated along the sediment-productive Mimi River in different flow conditions. We analyzed the following water quality components: suspended solids (SS), turbidity, total iron (TFe), dissolved iron (DFe), total organic carbon (TOC), total nitrogen (TN), total phosphorus (TP), humic substance (HS), and major ionic components (Na+, Mg2+, Ca2+, Cl-, NO3-, and SO42-) in the downstream channels of the three dams during the low-intermediate-flow and high-flow events from 2012 to 2014. We estimated hourly loads of each component using hourly turbidity data and discharge data (i.e., L-Q model) separately, and the results are integrated to estimate the annual fluxes. The annual fluxes between the methods were compared to verify predictability of the conventional L-Q models. Annual flux of TOC, TN, DFe, and HS estimated by the turbidity displayed similar values, whereas the flux of SS, TFe, and TP tended to increase downstream of the dams. Among the dams, estimated flux proportions for TP and TFe were higher during high-flow events (74%-94%). Considering geographic conditions (e.g., absence of major tributary between the dams), the result implies that accumulated TP and TFe in the reservoirs may be flushed and transported downstream with SS over the short height dams during flood events. Assuming this process, the reservoir dams probably make only a fractional contribution to the organic and inorganic transport in the catchment studied. The percent flux errors for SS, TFe, and TP fluxes ranged from -7.2% to -97% (except for the TP flux in 2013), which

The concentration of tritium in precipitation and river water has been measured sice 1973 in Aichi, Japan. The tritium in water samples was enriched by electrolysis, and measured by liquid scintillation counting. The concentration of tritium in precipitation decreased from 27 TU in 1973 to 17 TU in 1979, and showed seasonal variation. During this period, there was a rise of concentration because of Chinese nuclear detonation. The concentration of tritium in river water gradually decreased from 44 TU in 1973 to 24 TU in 1979, and the seasonal variation was not observed. Based on the observed values, the relation among precipitation, river water and ground water was analyzed. (J.P.N.)

Estimating insured residential losses from large flood scenarios on the Tone River, Japan - a data integration approach

2011-12-01

Flooding on the Tone River, which drains the largest catchment area in Japan and is now home to 12 million people, poses significant risk to the Greater Tokyo Area. In April 2010, an expert panel in Japan, the Central Disaster Prevention Council, examined the potential for large-scale flooding and outlined possible mitigation measures in the Greater Tokyo Area. One of the scenarios considered closely mimics the pattern of flooding that occurred with the passage of Typhoon Kathleen in 1947 and would potentially flood some 680 000 households above floor level. Building upon that report, this study presents a Geographical Information System (GIS)-based data integration approach to estimate the insurance losses for residential buildings and contents as just one component of the potential financial cost. Using a range of publicly available data - census information, location reference data, insurance market information and flood water elevation data - this analysis finds that insurance losses for residential property alone could reach approximately 1 trillion JPY (US 12.5 billion). Total insurance losses, including commercial and industrial lines of business, are likely to be at least double this figure with total economic costs being much greater again. The results are sensitive to the flood scenario assumed, position of levee failures, local flood depths and extents, population and building heights. The Average Recurrence Interval (ARI) of the rainfall following Typhoon Kathleen has been estimated to be on the order of 200 yr; however, at this juncture it is not possible to put an ARI on the modelled loss since we cannot know the relative or joint probability of the different flooding scenarios. It is possible that more than one of these scenarios could occur simultaneously or that levee failure at one point might lower water levels downstream and avoid a failure at all other points. In addition to insurance applications, spatial analyses like that presented here have

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

Turtles rank high in the river food chain, and are suitable for predicting the bioconcentrations of chemicals through the food chain. Trachemys scripta elegans (N=46) and Chinemys reevesii (N=51) were captured in a river in Japan, from September to October 2003 and April to June 2004. Surface water samples were collected simultaneously from the same sites at which the turtles were caught. Serum perfluorooctane sulfonate (PFOS) ranged from 2.4 to 486 microg/L, while water PFOS levels ranged from 2.9 to 37 ng/L. The geometric mean (GM) (geometric standard deviation, GSD) of the bioconcentration factor (BCF) of PFOS was 10,964 (2.5). In contrast, the perfluorooctanoate (PFOA) level in water ranged from 16.7-87,100 ng/L, and serum PFOA ranged from <0.2 to 870 microg/L. The GM (GSD) of the BCF of PFOA was 3.2 (7.9). Furthermore, the BCF of PFOA decreased as the PFOA level in the surface water increased. PFOS could be preferentially bioconcentrated in biota, and PFOA, slightly bioconcentrated.

Antibiotic-resistant E. coli concentrations showed large spatial and temporal variations, with greater concentrations observed in tributaries and downstream than in the upstream and midstream. Twenty percent of the geometric mean concentrations of antibiotic-resistant E. coli in the Tama River basin (Japan) exceeded the maximum acceptable concentration of indicator E. coli established by the USEPA. The indicator E. coli concentrations were positively correlated with those of antibiotic-resistant E. coli and multiple-antibiotic-resistant E. coli (resistance to more than two kinds of antibiotics), respectively, but not the detection rate of antibiotic-resistant E. coli, implying that use of antibiotic-resistant E. coli concentration rather than the detection rate can be a better approach for water quality assessment. Multiple-antibiotic-resistant E. coli is a useful indicator for estimating the resistance diffusion, water quality degradation and public health risk potential. This assessment provides beneficial information for setting national regulatory or environmental standards and managing integrated watershed areas. - Highlights: ► We extensively observed antibiotic-resistant E. coli (AREc) in Tama River (Japan). ► AREc count rather than the detection rate is better approach for water quality test. ► Multiple-AREc is resistant to the antibiotic to which single-AREc has no resistance. ► Multiple-AREc increase will accelerate the diffusion of antibiotic resistance. - Multiple-antibiotic-resistant E. coli in the watershed can cause the diffusion of conventionally rare antibiotic resistance.

REVIVE SE (REVIVE) is a closed-ended, self-expanding stent retriever used in the RIVER JAPAN study. We present our early experience with REVIVE for revascularization of acute ischemic stroke (AIS) in patients who have failed or are ineligible for intravenous recombinant tissue plasminogen activator treatment. This prospective, single-arm, non-randomized, multicenter registry study followed up patients undergoing mechanical thrombectomy with REVIVE for 90 days. The primary endpoint was a post-procedure Thrombolysis in Cerebral Infarction (TICI) score ≥2a. Secondary endpoints were clot migration/embolization; recanalization without symptomatic intracranial hemorrhage (ICH) at 24 h; symptomatic ICH; good neurological outcome (modified Rankin Scale score ≤2 National Institute of Health Stroke Scale (NIHSS) score decrease ≥10) at day 90; device- or procedure-related serious adverse events (SAEs) and mortality at day 90. To confirm non-inferiority of REVIVE, results were compared with historical data of the Merci Retriever. About 49 patients were enrolled (median age 73 years; males 46.9%; middle cerebral artery (MCA) occlusion 83.7%; median NIHSS score 17). A post-procedure TICI score ≥2a was observed in 73.5% (36/49, 95% confidence interval [CI] 58.9-85.1) of patients. No post-procedural clot migration/embolization events occurred. Successful recanalization without symptomatic ICH was observed in 62.5% (30/48, 95% CI 47.4-76.0). The good neurological outcome was achieved in 66.7% (32/48) patients. Symptomatic ICH and device- or procedure-related SAEs were reported in 6.3% and 12.2% of patients, respectively. Two deaths were reported. REVIVE demonstrated equivalent efficacy and safety as the Merci Retriever. Results suggest that REVIVE is effective and safe in recanalizing occluded intracranial arteries in AIS.

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

Tritium concentrations in natural waters in Japan before use of a large quantity of tritium on its fusion program

Kaji, Toshio; Momoshima, Noriyuki; Takashima, Yoshimasa.

To clarify environmental tritium levels in Japan before use of a large quantity of tritium on its fusion program, the authors analyzed the tritium concentrations in various water samples, such as rain, river, lake, coastal sea and deep sea waters in Japan. The tritium concentrations in rain water were high at higher latitude. The definite differences of the tritium concentrations due to the weather conditions or seasons were not observed. The average tritium concentration in river water was 51.5 pCi/l in 1982 and that in lake water was 63.5 pCi/l in 1983. The vertical profiles of the tritium concentrations in the representative lakes were almost homogeneous except surface water. The average tritium concentrations in coastal seawater were about 20 pCi/l in both 1982 and 1983. The tendency of the increased tritium level with latitude as reported in literature was not observed by these experiments. Tritium levels in natural water in small isolated islands were lower than those at other places. In the Japan Sea, it was recognized that tritium was distributed down to around 2000 m in depth. This means that the more active vertical mixing of water masses than that in the Pacific Ocean is taking place. (author)

Sediments of the Kitajukkengawa River (Sumida-ku, Tokyo, Japan) were analyzed by activation analyses. Concentrations of 36 elements for each sample were determined by instrumental neutron activation analysis (INAA) and neutron induced prompt gamma-ray analysis (PGA). Based on the correlation matrix between the elements in vertical distribution, principal component analysis (PCA) was performed. The degree of chemical weathering of silicate minerals was highest in the middle layer of the Kitajukkengawa River sediment and that adsorbed amount of trace metals such as Cd and Cr was increased along with chemical weathering.

Human impacts on river water quality- comparative research in the catchment areas of the Tone River and the Mur River-

2013-12-01

Human activities in river basin affect river water quality as water discharges into river with pollutant after we use it. By detecting pollutants source, pathway, and influential factor of human activities, it will be possible to consider proper river basin management. In this study, material flow analysis was done first and then nutrient emission modeling by MONERIS was conducted. So as to clarify land use contribution and climate condition, comparison of Japanese and European river basin area has been made. The model MONERIS (MOdelling Nutrient Emissions in RIver Systems; Behrendt et al., 2000) was applied to estimate the nutrient emissions in the Danube river basin by point sources and various diffuse pathways. Work for the Mur River Basin in Austria was already carried out by the Institute of Water Quality, Resources and Waste Management at the Vienna University of Technology. This study treats data collection, modelling for the Tone River in Japan, and comparative analysis for these two river basins. The estimation of the nutrient emissions was carried out for 11 different sub catchment areas covering the Tone River Basin for the time period 2000 to 2006. TN emissions into the Tone river basin were 51 kt/y. 67% was via ground water and dominant for all sub catchments. Urban area was also important emission pathway. Human effect is observed in urban structure and agricultural activity. Water supply and sewer system make urban water cycle with pipeline structure. Excess evapotranspiration in arable land is also influential in water cycle. As share of arable land is 37% and there provides agricultural products, it is thought that N emission from agricultural activity is main pollution source. Assumption case of 10% N surplus was simulated and the result was 99% identical to the actual. Even though N surplus reduction does not show drastic impact on N emission, it is of importance to reduce excess of fertilization and to encourage effective agricultural activity

This report was drawn up by the National Institute of Radiological Sciences. In order to measure tritium levels and consequently to assess the significance of the tritium in the environmental water around nuclear facilities regarding public health, the tritium surveillance program began in 1967 locally in Tsuruga and Mihama districts. Now, it has been expanded to 12 nuclear power stations and 5 nuclear facilities. In this report, the data from 1977 to 1980 are presented. Though the frequency of sampling was limited to once or twice a year in most cases, the time and point of measurement were fixed in each station in order to know the annual variation of tritium levels. The water samples were land water such as rivers, reservoirs and ponds and wells, sea water for secondary cooling system, and tap water around nuclear facilities, and land water, sea water and tap water in the places remote from nuclear facilities as the criteria. The samples with less than 100 pCi/l of tritium were electrolytically enriched, and counted with liquid scintillation counters. The results in respective facilities are reported. The tritium concentration in rivers, streams and reservoirs decreased exponentially from 400 pCi/l in 1971 to 100 pCi/l in 1980 with the half life of about 5 years in northeast Japan. Sea water was not affected by the effluent from nuclear facilities, and the tritium concentration in tap water was almost same as rivers. (Kako, I.)

Origins of total phosphorus (TP) and total nitrogen (TN) were investigated in the Seto Inland Sea, Japan, using the unit response function method. About 58 % of TP and TN in the Seto Inland Sea were found to have originated from the open ocean, 9 % of TP and 14 % of TN originate from rivers, 33 % of TP and 29 % of TN originate from bottom sediments. We consequently suggest that it would be very difficult to prevent the occurrence of red tides and oxygen deficient water masses in the Seto Inla...

Observation of Whole Flushing Process of a River Sand Bar by a Flood Using X-Band Radar

Full Text Available Morphological changes during a flood event in July 2010 were observed with X-band marine radar at the mouth of Tenryu River, Shizuoka, Japan. Radar images were collected hourly for more than 72 h from the beginning of the flood and processed into time-averaged images. Changes in the morphology of the area were interpreted from the time-averaged images, revealing that the isolated river dune was washed away by the flood, the width of the river mouth increased gradually, and the river mouth terrace expanded radially. Furthermore, image analysis of the radar images was applied to estimate the migration speed of the brightness pattern, which is assumed to be a proxy of bottom undulation of the river bed. The migration was observed to be faster when the water level gradient between the river channel and sea increased.

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

Tracing cohesive sediment transportation at river mouths around Tokyo, Japan by Cesium originated from Fukushima Daiichi Power Plant

koibuchi, Y.

2012-12-01

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

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

Networking Japan

Hansen, Annette Skovsted

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

The International River Interface Cooperative: Public Domain Software for River Flow and Morphodynamics (Invited)

The International River Interface Cooperative is an informal organization made up of academic faculty and government scientists with the goal of developing, distributing and providing education for a public-domain software interface for modeling river flow and morphodynamics. Formed in late 2007, the group released the first version of this interface (iRIC) in late 2009. iRIC includes models for two and three-dimensional flow, sediment transport, bed evolution, groundwater-surface water interaction, topographic data processing, and habitat assessment, as well as comprehensive data and model output visualization, mapping, and editing tools. All the tools in iRIC are specifically designed for use in river reaches and utilize common river data sets. The models are couched within a single graphical user interface so that a broad spectrum of models are available to users without learning new pre- and post-processing tools. The first version of iRIC was developed by combining the USGS public-domain Multi-Dimensional Surface Water Modeling System (MD_SWMS), developed at the USGS Geomorphology and Sediment Transport Laboratory in Golden, Colorado, with the public-domain river modeling code NAYS developed by the Universities of Hokkaido and Kyoto, Mizuho Corporation, and the Foundation of the River Disaster Prevention Research Institute in Sapporo, Japan. Since this initial effort, other Universities and Agencies have joined the group, and the interface has been expanded to allow users to integrate their own modeling code using Executable Markup Language (XML), which provides easy access and expandability to the iRIC software interface. In this presentation, the current components of iRIC are described and results from several practical modeling applications are presented to illustrate the capabilities and flexibility of the software. In addition, some future extensions to iRIC are demonstrated, including software for Lagrangian particle tracking and the prediction of

Matsubaya, Osamu; Yoshida, Minako; Tanaka-Miyamoto, Kiriko.

1990-01-01

By means of three isotope tracer techniques, proportion of direct runoff and characters of groundwater runoff were studied in the Iwami River drainage during a high runoff period for about 3 days, caused by a heavy rainfall of 85 mm for 17 hours. The proportion of direct runoff is 15 % or less of the total runoff caused by the rainfall, while 65 % of river water at the peak of runoff. Differences observed in the runoff manners among 18 O, 2 H, and 3 H are interpreted as a result of preferential runoff of previous precipitations stored in some unsaturated zone above the saturated groundwater zone. Cl - content is not conservative as a tracer to study runoff mechanisms. (author)

Redox speciation of particulate iron and manganese during river/ocean mixing

2000-01-01

Full text: A synchrotron radiation experiment was performed at the Australian National Beamline Facility (Photon Factory, Tsukuba, Japan) to investigate changes in the physico-chemical nature of particles during estuarine mixing. X-ray absorption near edge structure spectra (XANES) analysis was used to determine solid-state redox speciation of iron and manganese throughout the river/ocean salinity transects. Particles (>0.4μm) collected using clean techniques were stored under nitrogen during TROPICS Project expeditions to the Fly and Sepik Rivers, PNG. Results indicated that initially, particulate manganese was mostly present as Mn(IV) and Mn(III) compounds with some surface-adsorbed Mn(II). Similarly, iron was present as particulate Fe(III) and Fe(II/III) compounds with some adsorbed Fe(II). During river-ocean mixing, the proportions of both Mn(II) and Fe(III) significantly increased. These observations maybe due to increasing photochemical activity in the river plume, surface-sorption of reduced species related to the estuarine residence time of particles, or enhanced scavenging of ocean-sourced elements.

The determination of 34 trace metals in a river water certified reference material (CRM), i.e. JSAC 0301-1, which was issued by the Japan Society for Analytical Chemistry in January 2004, was performed by ICP-MS with a high efficiency nebulizer after preconcentration with a laboratory-made chelating resin-packed minicolumn, with which trace metals were concentrated 100-fold from 50 mL of a river water sample to 0.5 mL of the final analysis solution. Trace metals in JSAC 0301-1 were observed in the concentration range from 19 μg L -1 of Al to 0.000053 μg L -1 of Bi. It was found that most of the concentrations of trace metals, including rare earth elements (REEs), in JSAC 0301-1 were lower than those in JAC 0031, which was also a previously issued CRM prepared with water from the same river as that of JSAC 0301-1. The low concentrations of trace metals in JSAC 0301-1 might be attributed to the fact that there was heavy rain before collecting the original water sample to prepare the present CRM. Furthermore, the REE distribution patterns of JSAC 0301-1, JAC 0031 and the average values of river water samples in Japan were parallel to each other. These results indicate that the distributions of REEs in JSAC 0301-1 and JAC 0031 were the typical ones of river water samples in Japan. (author)

Detailed study of different sections of floodplain was undertaken in the Niida River basin (Fukushima Prefecture) after an extreme flood event which occurred in the middle of September 2015. The upstream part of the basin is located in the area with very high level of radionuclide contamination after the accident at Fukushima Dai-ichi NPP. Field and GIS methods were used, including direct measurement of the depth of fresh sediment and its area, with soil descriptions for the typical floodplain sections, measurement of dose rates, interpretation of space images for a few time intervals (before and after flood event) with the following evaluation of spatial changes in deposition for different floodplain sections. In addition, results of quantitative assessment of sedimentation rates and soil radionuclide contamination were applied for understanding the effect of extreme flood on alluvial soils of the different sections. It was established that the maximum sedimentation rates (20-50 cm/event) occurred in the middle part of the lower reach of the Niida River and in some locations of the upper reaches. Dose rates had reduced considerably for all the areas with high sedimentation because the top soil layers with high radionuclide contamination were buried under fresh sediments produced mostly due to bank erosion and mass movements.

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

Science.gov (United States)

Umemura, Maki

2010-01-01

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

Migration through the Eastern Palearctic (EP) flyway by tundra swans (Cygnus columbianus) has not been thoroughly documented. We satellite-tracked the migration of 16 tundra swans that winter in Japan. The objectives of this study were 1) to show the migration pattern of the EP flyway of tundra swans; 2) to compare this pattern with the migration pattern of whooper swans; and 3) to identify stopover sites that are important for these swans' conservation. Tundra swans were captured at Kutcharo Lake, Hokkaido, in 2009-2012 and satellite-tracked. A new method called the "MATCHED (Migratory Analytical Time Change Easy Detection) method" was developed. Based on median, the spring migration began on 18 April and ended on 27 May. Autumn migration began on 9 September and ended on 2 November. The median duration of the spring and autumn migrations were 48 and 50 days, respectively. The mean duration at one stopover site was 5.5 days and 6.8 days for the spring and autumn migrations, respectively. The number of stopover sites was 3.0 and 2.5 for the spring and autumn migrations, respectively. The mean travel distances for the spring and autumn migrations were 6471 and 6331 km, respectively. Seven migration routes passing Sakhalin, the Amur River, and/or Kamchatka were identified. There were 15, 32, and eight wintering, stopover, and breeding sites, respectively. The migration routes and staging areas of tundra swans partially overlap with those of whooper swans, whose migration patterns have been previously documented. The migration patterns of these two swan species that winter in Japan confirm the importance of the Amur River, Udyl' Lake, Shchastya Bay, Aniva Bay, zaliv Chayvo Lake, zal Piltun Lake, zaliv Baykal Lake, Kolyma River, Buyunda River, Sen-kyuyel' Lake, and northern coastal areas of the Sea of Okhotsk.

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

Modeling nearshore dispersal of river-derived multi-class suspended sediments and radionuclides during a flood event around the mouth of Niida River, Fukushima, Japan

A quadruple nested synoptic oceanic downscale modeling based on ROMS was carried out to investigate hydrodynamics, multi-class non-cohesive sediment transport and associated dispersal of suspended radionuclides (cesium-137; 137Cs) originated from the nuclear accident occurred at the Fukushima Dai-ichi Power Plant in March 2011. The innermost model has horizontal grid resolution of 50 m to marginally resolve the topography around the river mouth including the surf zone. The model is forced by the JCOPE2 oceanic reanalysis as the outermost boundary conditions, the GPV-MSM atmospheric reanalysis, and an in-house SWAN spectral wave hindcast embedded in the operational GPV-CWM wave reanalysis. A particular attention is paid to nearshore behaviors and inventory of the nuclides attached to terrestrial minerals with grain sizes ranging from 5 to 79 micrometers that have been occasionally discharged out to the coastal ocean through hydrological processes within the river basin even after several years since the accident. We examine oceanic dispersal of sediment and suspended 137Cs influxes from Niida River, Fukushima, evaluated with the iRIC-Nays2DH river model. Our focus is on the first flood event in late May of 2011 after the accident. Alongshore asymmetry in transport of suspended sediments and 137Cs is exhibited, comprising storm-driven southward transport confined in the shallow area due to shoreward Ekman transport associated with strong northerly wind, followed by northwestward wide-spread transport under mild southerly wind condition. About 70 % of the Niida River-derived suspended 137Cs remains near the mouth for 20 days after the flood event. Nevertheless, our model results as well as an observation suggest that the area is dominated by erosion as for high bed shear stress all the time, thus suspended radionuclides are redistributed to dissipate away in long term.

Surface waters including river water and effluent from sewage treatment plants (STPs) were collected from Tokyo Bay watershed, Japan, and analyzed for seven cyclic and linear volatile methylsiloxanes (VMSs), i.e., D3, D4, D5, D6, L3, L4, and L5 by an optimized purge and trap extraction method. The total concentrations of seven VMSs (ΣVMS) in river water ranged from watershed was estimated at 2300kg. Our results indicate widespread distribution of VMSs in Tokyo Bay watershed and the influence of domestic wastewater discharges as a source of VMSs in the aquatic environment.

We found that shading effects were more prevalent in the immediate vicinity of LW pieces than in quadrats distant from LW. The effect was...

Influences of channelization on discharge of suspended sediment and wetland vegetation in Kushiro Marsh, northern Japan

The effects of wetlands on hydrology, water quality, and wildlife habitat are internationally recognized. Protecting the remaining wetlands is one of the most important environmental issues in many countries. However wetlands in Japan have been gradually shrinking due to agricultural development and urbanization, which generally lowers the groundwater level and introduces suspended sediment and sediment-associated nutrients into wetlands. We examined the influences of channelization on discharge of suspended sediment and wetland vegetation in Hokkaido, northern Japan. The impact of river channelization was confirmed not only by the sediment budgets but also by river aggradation or degradation after the channelization and by the resultant vegetational changes. The budgets of suspended sediment demonstrated that wash load was the predominant component accounting for 95% of the total suspended load delivered into the wetland. This suspended sediment was primarily transported into the wetland by flooding associated with heavy rainfall. Twenty-three percent of the wash load and 63% of the suspended bed material load were deposited in the channelized reach, which produced aggradation of about 2 m at the end of the reach. A shorting of the length of the channel, due to channelization of a meandering river, steepened the slope and enhanced the stream power to transport sediment. This steepening shifted the depositional zones of fine sediment 5 km downstream and aggraded the riverbed. Development of the watershed may increase not only the water discharge but also the amount of suspended sediments. The aggradation reduced the carrying capacity of the channel and caused sediment ladened water to flood over the wetlands. The fine sediment accumulated on the wetlands gradually altered the edaphic conditions and wetland vegetation. A low percentage (10 to 15%) of organic contents of wetlands' soil is more evidence indicating that the present condition is far different from

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

We review case studies of stakeholder participation in the environmental cleanup of radioactive wastes in the United States, Japan and United Kingdom (e.g., [21,26,27,66,78]). Citizen participation programs in these three countries are at different stages: mature in the US, starting in Japan, and becoming operational in the UK. The US issue at the US Department of Energy's (DOE) Savannah River Site (SRS) in South Carolina (SC) had been focused on citizens encouraging Federal (DOE; US Environmental Protection Agency, or EPA; and the US Nuclear Regulatory Commission, or NRC) and State (SC's Department of Health and Environmental Compliance, or DHEC) agencies to pursue 'Plug-in-RODs' at SRS to simplify the regulations to accelerate closing seepage basins at SRS. In Japan, the Reprocessing of spent fuel and deep geological disposal of vitrified high-level waste have been among Japan's priorities. A reprocessing plant in Rokkasho, Aomori Prefecture is expected to commence operations in October 2010. The search of a site for a deep geological disposal facility has been ongoing since 2002. But the direct engagement of stakeholders has not occurred in Japan. Indirectly, stakeholders attempt to exert influence on decision-making with social movements, local elections, and litigation. In the UK, the issue is gaining effective citizen participation with the UK's Nuclear Decommissioning Authority (NDA). We hope that the case studies from these countries may improve citizen participation. (author)

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

Japan`s civil use of foreign military plutonium

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

1995-12-31

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

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

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.

With an objective to give some suggestion to the water resources policies for the future Japan, a comparative study was made on the water resources development policies in Japan and the water resources policies in the state of California, U.S.A. The study on Japan has been proceeded empirically based on specific data with regard to the development of electric power policies from the prewar to postwar times when the governmental electric power control was changed to incorporation of the nine electric power companies. The change may be identified from viewpoints of both profit and ideology. Noticing the `public corporations` established one after another for social capitals before and after the establishment of the Liberal Democratic Party, their relation with the water resources development policies was pursued in terms of actual proof and political science. The identity of the public corporations established in and after 1955 stands on the premise of free economy, rather than the controlled economy. This paper positions the water resources development policies in a broader context as the national land plan, and considers the problems that are expanding from flood damages, dam construction, industrial complex construction to environmental problems around the water. Comparative discussions on the Tone river system and the Colorado river system were left as the future assignment.

Institutionalisation of Japan Identity Construction Policy

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

Radioactive materials were released into the atmosphere and deposited over wide areas of farmland, forests, and cities; elevated levels of "1"3"1I, "1"3"4Cs, and "1"3"7Cs have been detected in these areas due to the accident at the Tokyo Power Fukushima Daiichi Nuclear Power Plant caused by the April 2011 earthquake and tsunami in eastern Japan. Radioactive Cs deposited on farmland and forests gradually leaches into water bodies such as mountain streams and rivers adsorbed onto particles or in a dissolved state. It is important to calrify the level of dissolved and total radioactive Cs in environmental water for forecasting the of discharge of radioactive Cs from forest and watersheds, assessing on the effect of dissolved and total radioactive Cs on not only irrigation water but also rice and other crops, and evaluating the transport of radioactive Cs from rivers to costal areas. Therefore, it is important to monitor their levels in Fukushima Prefecture over time. In this research, we monitored the levels of dissolved and total radioactive Cs in Abukuma River using a conventional evaporative concentration method. By monitoring the river waters since September 2012, it was estimated that the levels of dissolved radioactive Cs were less than 0.128 Bq/L and those of total radioactive Cs were less than 0.274 Bq/L in the main stream and branches of Abukuma River in the low suspended solid condition.

This article describes the principal control parameters of flood events and precipitation and the relationships between corresponding hydrologic and climatologic parameters. The long-term generation of runoff and associated processes is important in understanding floods and droughts under changes in climate and land use. This study presents detailed analyses of flood events in a coastal amphitheatre catchment with a total area of 445 km 2 in western Japan, followed by analyses of flood events in both urban and forest areas. Using long-term (1962 to 2002) hydrological and climatological data from the Ministry of Land, Infrastructure and Transport, Japan, the contributions of precipitation, river discharge, temperature, and relative humidity to flood events were analysed. Flood events could be divided into three types with respect to hydrologic and climatologic principal control parameters: the long-term tendency; medium-term changes as revealed by hydrographs and hyetographs of high-intensity events such as the relative precipitation, river discharge, and temperature; and large events, as shown by the flow-duration curve, with each cluster having particular characteristics. River discharge showed a decreasing tendency of flow quantity during small rainfall events of less than 100 mm/event from the 1980s to the present. An approximately 7% decrease from 44.8 to 37.3% occurred in the percentage of river water supplied by precipitation in the years after the 1980s. For the medium-term changes, no marked change occurred in the flow quantity of the peak point over time in event hydrographs. However, flow quantities before and after the peak tended to decrease by 1 to 2 m 3/s after the 1980s. Theoretical considerations with regard to the influence of hydrologic and climatologic parameters on flood discharge are discussed and examined in terms of observational data. These findings provide a sound foundation for use in hydrological catchment modelling.

2016-08-01

Full Text Available In this study, in order to determine the efficiency of estimating annual water pollution loads from remote-sensed land cover classification and ground-observed hydrological data, an empirical model was investigated. Remote sensing data imagery from National Oceanic and Atmospheric Administration (NOAA Advanced Very High Resolution Radiometer were applied to an 11 year (1994–2004 water quality dataset for 30 different rivers in Japan. Six water quality indicators—total nitrogen (TN, total phosphorus (TP, biochemical oxygen demand (BOD, chemical oxygen demand (COD, and dissolved oxygen (DO—were examined by using the observed river water quality data and generated land cover map. The TN, TP, BOD, COD, and DO loads were estimated for the 30 river basins using the empirical model. Calibration (1994–1999 and validation (2000–2004 results showed that the proposed simulation technique was useful for predicting water pollution loads in the river basins. We found that vegetation land cover had a larger impact on TP export into all rivers. Urban areas had a very small impact on DO export into rivers, but a relatively large impact on BOD and TN export. The results indicate that the application of land cover data generated from the remote-sensed imagery could give a useful interpretation about the river water quality.

Problems in Siting Nuclear Power Plants in Japan and Efforts to Solve Them

Energy Technology Data Exchange (ETDEWEB)

Inouye, T. [Ministry of International Trade and Industry, Tokyo (Japan)

1967-09-15

The rapidly growing demand for energy in Japan will require a total capacity of 30 to 40 thousand MW(e) in nuclear power by 1985. Materialization of this development programme must naturally be supported by securing the requisite sites for the nuclear power plants. The following factors make siting of nuclear power plants more difficult in Japan than in any other country: a small, densely populated territory with little level land, that is already completely utilized for agricultural and/or industrial purposes; small rivers and an active marine-product industry developed along most of the seacoasts, both of which create difficult cooling-water problems; frequent earthquakes; and the fear of possible radioactivity, which prevails in the only nation in the world to have suffered from the atomic bomb. There are at present four nuclear power plants in operation or under construction in Japan with a total capacity of about 1.3 thousand MW(e). However, the plants in these construction programmes have been sited on the basis of taking the easiest course available although there were several possible solutions to choose from. It is pointed out here that the long-range nuclear power development programme will call for a fundamental solution to enable siting a large number of power plants under the adverse conditions in Japan. Accordingly, a study was made, which included quantitative analyses of reactor siting factors and suggested measures for solving the siting problems. The analyses were based on nuclear power plant sites assumed to be located on the seacoast and characterized by low-population density, desirable geology and favourable topography. It was assumed that seacoast siting was more economical than inland siting. Although the study was made by a general survey using maps, it was shown that approximately 10% of the total coastline areas would be eligible for reactor siting, but most of these areas in this case are located in the northern part of Japan, far from

Japan steel mill perspective

Energy Technology Data Exchange (ETDEWEB)

Murase, K. [Kobe Steel Ltd., Tokyo (Japan)

2004-07-01

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

Recently, fondaparinux and edoxaban are being used as beneficial alternatives to UFH and VKA.Methods: We evaluated the clinical course of symptomatic deep vein thrombosis (DVT in patients who received the 3-month anticoagulation therapy with fondaparinux/edoxaban (Group A; n=40 in comparison with the findings from our previous experience of patients who received the fondaparinux/VKA combination (Group B; n=33.Results: In both Groups A and B, serum D-dimer was significantly improved after treatment (p<0.001. The thrombus volume assessed by quantitative ultrasound thrombosis (QUT score was significantly reduced in both groups (p<0.001. There was no difference in the proportion of patients who were normalized (ie, disappearance of DVT between the groups, although Group A had significantly more patients who were normalized or improved (ie, disappearance and reduction of DVT (p<0.001. No bleeding event was observed in either group. However, in one patient in Group B, worsening of DVT and development of symptomatic PE were observed.Conclusion: Fondaparinux/edoxaban therapy is as effective as fondaparinux/VKA. This treatment has the possible advantage in thrombus regression. This would be a beneficial therapeutic option for both patients and physicians.

2012-01-01

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

Japan's nuclear juggernaut

International Nuclear Information System (INIS)

Richner, S.

1984-01-01

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

The indicator bacteria (standard plate count, total coliform, and fecal coliform bacteria) concentrations have been investigated using six ambient habitats (population density, percent sewer penetration, stream flow rate (m(3)/sec), percent residential area, percent forest area and percent agricultural area) in the Tama River basin in Tokyo, Japan during June 2003 to January 2005. The downstream and tributary Tama River showed higher concentrations of TC and FC bacteria than the upstream waters, which exceeded an environmental quality standard for rivers and a bathing water quality criterion. It was estimated that combined sewer overflow (CSO) and stormwater effluents contributed -4-23% to the indicator bacteria concentrations of the Tama River. The results of multiple regression analyses show that the indicator bacteria concentrations of Tama River basin are significantly affected by population density. It is concluded that the Tama River received a significant bacterial contamination load originating from the anthropogenic source.

An automated system to simulate the River discharge in Kyushu Island using the H08 model

2015-12-01

Kyushu Island is located in southwestern part of Japan, and it is often affected by typhoons and a Baiu front. There have been severe water-related disasters recorded in Kyushu Island. On the other hand, because of high population density and for crop growth, water resource is an important issue of Kyushu Island.The simulation of river discharge is important for water resource management and early warning of water-related disasters. This study attempts to apply H08 model to simulate river discharge in Kyushu Island. Geospatial meteorological and topographical data were obtained from Japanese Ministry of Land, Infrastructure, Transport and Tourism (MLIT) and Automated Meteorological Data Acquisition System (AMeDAS) of Japan Meteorological Agency (JMA). The number of the observation stations of AMeDAS is limited and is not quite satisfactory for the application of water resources models in Kyushu. It is necessary to spatially interpolate the point data to produce grid dataset. Meteorological grid dataset is produced by considering elevation dependence. Solar radiation is estimated from hourly sunshine duration by a conventional formula. We successfully improved the accuracy of interpolated data just by considering elevation dependence and found out that the bias is related to geographical location. The rain/snow classification is done by H08 model and is validated by comparing estimated and observed snow rate. The estimates tend to be larger than the corresponding observed values. A system to automatically produce daily meteorological grid dataset is being constructed.The geospatial river network data were produced by ArcGIS and they were utilized in the H08 model to simulate the river discharge. Firstly, this research is to compare simulated and measured specific discharge, which is the ratio of discharge to watershed area. Significant error between simulated and measured data were seen in some rivers. Secondly, the outputs by the coupled model including crop growth

Spent fuel management in Japan

1996-01-01

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

Characteristics of Wet Deposition in Japan

Iwasaki, A.; Arakaki, T.

2017-12-01

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

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

Japan's electronic packaging technologies

Tummala, Rao R.; Pecht, Michael

1995-02-01

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

2017-01-01

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

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

The Red-crowned Crane Grus japonensis is an endangered species that has two separate breeding populations, one in the Amur River basin and the other in north and east Hokkaido, Japan. So far, only two (Gj1 and Gj2) and seven (Gj3-Gj9) haplotypes in D-loop of mtDNA were identified in Japan and in the continent, respectively. We obtained feathers from three cranes found in northeast Honshu. The crane in Akita in 2008, which also arrived at west Hokkaido, had a novel haplotype (Gj10). Another crane in Akita in 2009 showed a heteroplasmy (Gj7 and a novel type, Gj12). The third crane in Miyagi in 2010 also showed another type, Gj11. These results suggest that three Red-crowned Cranes appeared in Honshu and west Hokkaido were from the continent.

Geothermal properties and groundwater flow estimated with a three-dimensional geological model in a late Pleistocene terrace area, central Japan

1. Introduction The ground source heat pump (GSHP) is a highly efficient and renewable energy technology for space heating and cooling, with benefits that include energy conservation and reductions in greenhouse gas emissions. One result of the huge Tohoku-oki earthquake and tsunami and the subsequent nuclear disasters is that GSHPs are receiving more attention from the media and they are being introduced by some local governments. Heat generated by underground GSHP installation, however, can pollute the geothermal environment or change groundwater flow patterns . In this study, we estimated possible effects from the use of GSHPs in the Tokyo area with a three-dimensional (3D) geological model. 2. Geological model The Tokyo Metropolitan Area is surrounded by the Late Pleistocene terraces called the Musashino uplands. The terrace surfaces are densely populated residential areas. One of these surfaces, the Shimosueyohi surface, formed along the Tama River during the last deglacial period. The CRE-NUCHS-1 core (Funabiki et al., 2011) was obtained from this surface, and the lithology, heat transfer coefficients, and chemical characteristics of the sediments were analyzed. In this study, we used borehole log data from a 5 km2 area surrounding the CRE-NUCHS-1 core site to create a 3D geological model. In this area, the Pleistocene Kazusa Group is overlain by terrace gravels and a volcanic ash layer called the Kanto Loam. The terrace gravels occur mainly beneath the Kanda, Kitazawa, and Karasuyama rivers , which flow parallel to the Tama River, whereas away from the rivers , the Kanto Loam directly overlies the Kazusa Group sediments. 3. Geothermal disturbance and groundwater flow Using the geological model, we calculated the heat transfer coefficients and groundwater flow velocities in the sediments. Within the thick terrace gravels, which are at relatively shallow depth (8-20 m), heat transfer coefficients were high and groundwater flow was relatively fast. The amount

1992-01-01

In Japan, atomic energy has become to accomplish the important role in energy supply. Recently the interest in the protection of global environment heightened, and the anxiety on oil supply has been felt due to the circumstances in Mideast. Therefore, the importance of atomic energy as an energy source for hereafter increased, and the future plan of nuclear fuel recycling in Japan must be promoted on such viewpoint. At present in Japan, the construction of nuclear fuel cycle facilities is in progress in Rokkasho, Aomori Prefecture. The prototype FBR 'Monju' started the general functional test in May, this year.

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 Additional Protocol between Japan and the IAEA entered into force in December 1999. To come into force a series of implementation trials of Additional Protocol was carried out at two Japanese representative nuclear research centers, i.e. Tokai Research Establishment of Japan Atomic Energy Research Institute (JAERI) and Oarai Engineering Center of Japan Nuclear Fuel Cycle Development Institute (JNC). These trials were proposed by Japan and were conducted in cooperation with the IAEA Secretariat. In addition, Japan amended 'the Law for the Regulation of Reactors etc.', to collect adequate information to submit to the IAEA, to arrange the surrounding for the complementary access, etc. In addition, Japan Submitted the Initial Declaration of the Additional Protocol within 180 days of the entry into force of the Protocol, in the middle of June, 2000

Japan's new energy policy

International Nuclear Information System (INIS)

2014-11-01

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

New hydrological insights for the region: The geochemical mapping showed that As in river water exceeded the maximum limit concentration of 10 ppb in several places. The highest As levels (waters and sediments correlated well with the surface geologies, concentrating in a halo around granitic intrusion and nearby faults. The isotopic analysis of sulfur revealed the occurrence of two kinds of sulfide mineralizations responsible for As contamination: one from Late Paleozoic submarine volcanism in sedimentary rocks, and one from Late Cretaceous igneous activities in contact-metamorphosed rocks disseminated with sulfides. The transport of As along river courses occurred mainly as a dissolved species rather than absorbed on Fe/Mn/Al particles, signifying the least role of iron oxy-hydroxides in As adsorption.

The Yoshino river is one of the most prominent rivers in Japan, representing the Shikoku district, with the trunk length of 194km and the basin of 3,750km{sup 2} extending in 4 prefectures in the district. The upstream area includes areas where the average annual rainfalls exceed 3,000mm, being famous as a high-rain zone. The basic water level stream is 24,000m{sup 3} s which is one of the largest in Japan. Schistosity develops with the Sambagawa metamorphic rocks, which tend to be easily weathered. As a result, there are many landslide spots distributed in the Sambagawa belt. The Shikoku district as a whole has one fifth of the landslide dangerous areas of Japan. Countermeasure activities against landslides were initiated in 1982 in Tokushima and Kochi prefectures. Outlines of landslides in those areas, underground structure, activity of landsliding, countermeasure activity against landslides, and the result of the activity are introduced. 12 figs.

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

yield for all of Japan is considered, both scenarios produced an approximately 17–18% increase around the first half of the 21st century as compared to the present climate. For the second half of the century, the MIROC and MRI-RCM20 scenarios predict increased sediment yields of 22% and 14%, respectively, as compared to present climate estimations. On a regional scale, both scenarios identified several common areas prone to increased sediment yields in the future. Substantially higher specific sediment yield changes (over 1000 m³/km²/year were estimated for the Hokuriku, Kinki and Shikoku regions. Out of 105 river basins in Japan, 96 will have an increasing trend of sediment yield under a changing climate, according to the predictions. Among them, five river basins will experience an increase of more than 90% of the present sediment yield in the future. This study is therefore expected to guide decision-makers in identifying the basins that are prone to sedimentation hazard under a changing climate in order to prepare and implement appropriate mitigation measures to cope with the impacts.

IAEA Remediation Mission to Japan Concludes

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

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

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

Epidemiology of diabetes mellitus in Japan

Energy Technology Data Exchange (ETDEWEB)

Blackard, W G; Omori, Yoshiaki; Freedman, L R

1964-03-12

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

Process-based distributed modeling approach for analysis of sediment dynamics in a river basin

Directory of Open Access Journals (Sweden)

M. A. Kabir

2011-04-01

Full Text Available Modeling of sediment dynamics for developing best management practices of reducing soil erosion and of sediment control has become essential for sustainable management of watersheds. Precise estimation of sediment dynamics is very important since soils are a major component of enormous environmental processes and sediment transport controls lake and river pollution extensively. Different hydrological processes govern sediment dynamics in a river basin, which are highly variable in spatial and temporal scales. This paper presents a process-based distributed modeling approach for analysis of sediment dynamics at river basin scale by integrating sediment processes (soil erosion, sediment transport and deposition with an existing process-based distributed hydrological model. In this modeling approach, the watershed is divided into an array of homogeneous grids to capture the catchment spatial heterogeneity. Hillslope and river sediment dynamic processes have been modeled separately and linked to each other consistently. Water flow and sediment transport at different land grids and river nodes are modeled using one dimensional kinematic wave approximation of Saint-Venant equations. The mechanics of sediment dynamics are integrated into the model using representative physical equations after a comprehensive review. The model has been tested on river basins in two different hydro climatic areas, the Abukuma River Basin, Japan and Latrobe River Basin, Australia. Sediment transport and deposition are modeled using Govers transport capacity equation. All spatial datasets, such as, Digital Elevation Model (DEM, land use and soil classification data, etc., have been prepared using raster "Geographic Information System (GIS" tools. The results of relevant statistical checks (Nash-Sutcliffe efficiency and R–squared value indicate that the model simulates basin hydrology and its associated sediment dynamics reasonably well.

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

Analysis of energy intensity in Japan

Okajima, Shigeharu; Okajima, Hiroko

2013-01-01

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

2011-01-01

In order to assess the long-term safety of a geological disposal system for high-level radioactive waste (HLW), it is important to consider the impact of uplift and erosion, which cannot be precluded on a timescale in the order of several hundred thousand years for many locations in Japan. Geomorphic evolution, caused by uplift and erosion and coupled to climatic and sea-level changes, will impact the geological disposal system due to resulting spatial and temporal changes in the disposal environment. Degradation of HLW barrier performance will be particularly significant when the remnant repository structures near, and are eventually exposed at, the ground surface. In previous studies, fluvial erosion was densified as the key concern in most settings in Japan. Interpretation of the impact of the phenomena at relevant locations in Japan has led to development of a generic conceptual model which contains the features typical at middle reach of rivers. Here, therefore, we present a methodology for development of a generic conceptual model based on best current understanding of fluvial erosion in Japan, which identifies the simplifications and uncertainties involved and assesses their consequences in the context of repository performance.

Geomorphic impacts of a disastrous crevasse splay that formed in September 2015 and its post-formation modifications were quantitatively documented by using repeated, high-definition digital surface models (DSMs) of an inhabited and cultivated floodplain of the Kinu River, central Japan. The DSMs were based on pre-flood (resolution: 2 m) and post-flood (resolution: 1 m) aerial light detection and ranging (lidar) data from January 2007 and September 2015, respectively, and on structure-from-motion (SfM) photogrammetry data (resolution: 3.84 cm) derived from aerial photos taken by an unmanned aerial vehicle (UAV) in December 2015. After elimination of systematic errors among the DSMs and down-sampling of the SfM-derived DSM, elevation changes on the order of 10-1 m - including not only topography but also growth of vegetation, vanishing of flood waters, and restoration and repair works - were detected. Comparison of the DSMs showed that the volume eroded by the flood was more than twice the deposited volume in the area within 300-500 m of the breached artificial levee, where the topography was significantly affected. The results suggest that DSMs based on a combination of UAV-SfM and lidar data can be used to quantify, rapidly and in rich detail, topographic changes on floodplains caused by floods.

Recent trends for drug lag in clinical development of oncology drugs in Japan: does the oncology drug lag still exist in Japan?

Science.gov (United States)

Maeda, Hideki; Kurokawa, Tatsuo

2015-12-01

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

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

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

Katzenstein, P.J.; Okawara, N.

1993-01-01

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

Sources and transformations of dissolved lignin phenols and chromophoric dissolved organic matter in Otsuchi Bay, Japan

Chia-Jung eLu

2016-06-01

Full Text Available Dissolved lignin phenols and optical properties of dissolved organic matter (DOM were measured to investigate the sources and transformations of terrigenous DOM (tDOM in Otsuchi Bay, Japan. Three rivers discharge into the bay, and relatively high values of syringyl:vanillyl phenols (0.73 ± 0.07 and cinnamyl:vanillyl phenols (0.33 ± 0.10 indicated large contributions of non-woody angiosperm tissues to lignin and tDOM. The physical mixing of river and seawater played an important role in controlling the concentrations and distributions of lignin phenols and chromophoric DOM (CDOM optical properties in the bay. Lignin phenol concentrations and the CDOM absorption coefficient at 350 nm, a(350, were strongly correlated in river and bay waters. Measurements of lignin phenols and CDOM in bay waters indicated a variety of photochemical and biological transformations of tDOM, including oxidation reactions, photobleaching and a decrease in molecular weight. Photodegradation and biodegradation of lignin and CDOM were investigated in decomposition experiments with river water and native microbial assemblages exposed to natural sunlight or kept in the dark. There was a rapid and substantial removal of lignin phenols and CDOM during the first few days in the light treatment, indicating transformations of tDOM and CDOM can occur soon after discharge of buoyant river water into the bay. The removal of lignin phenols was slightly greater in the dark (34% than in the light (30% during the remaining 59 days of the incubation. Comparison of the light and dark treatments indicated biodegradation was responsible for 67% of total lignin phenol removal during the 62-day incubation exposed to natural sunlight, indicating biodegradation is a dominant removal process in Otsuchi Bay.

Introduction Coral reefs are subjected to artificial chemicals such as herbicide and pesticides. Diuron [N'-(3, 4-dichlorophenyl)-N, N-dimethylurea] is one of the active constituent contained in a herbicide. Although acute effects of diuron on coral are reported by several researchers, longer-period toxicity with lower level concentration and synergistic effect between the herbicide and soil sedimentation from river water have not been studied. We investigated the concentration level, distribution, seasonal variation and accumulation of several herbicides and pesticides in coral reef and river in Ishigaki Island and Okinawa Island, and estimated the rates of carbon production of calcification and photosynthesis to access the effects of herbicides on coral. Materials and Methods Water and sediment samples were collected from Todoroki river and Shiraho coral reef in Ishigaki Island and several rivers from Okinawa Island in August 2010 to August 2011. Diuron and other active constituents were extracted using a solid-phase column and measured with a liquid chromatography-tandem mass spectrometry (LC-MS/MS). Corals for the experiment were collected from Okinawa Island and incubated in glass bottles. Seawater adjusted several concentrations of herbicide was continuously supplied to the bottles. Coral calcification and photosynthesis were estimated based on the change in total alkalinity and pH during a few hours when we temporary cease the water flow. Results and Discussion Higher diuron of 563 ng/L in water and 26 μg/kg in sediment was detected at the headwater of the Todoroki river in Ishigaki. in June. Sugarcane plantation is prevailing in Todoroki river area and rainwater can tend to gather topographically to upstream of the river. The higher concentration at the headwater decreased to 23 ng/L toward the river mouth. On the whole, the concentrations were higher during summer and lower in the other seasons in Ishigaki. On the other hand, seasonal variation was not

Wastewater and solid waste from both domestic and industry have been known to give burden on river water quality. Most of river water quality problem in Indonesia has start in the upper part of river due to anthropogenic activities, due to inappropriate land use management including the poor wastewater infrastructure. Base on Upper Citarum River Water pollution problem, it is interesting to study the other main river in Java Island. Bengawan Solo River and Brantas River were chosen as the sample in this study. Parameters assessed in this study are as follows: TSS, TDS, pH, DO, and hexavalent chromium. The status of river water quality are assess using STORET method. Based on (five) parameters, STORET value showed that in Brantas River, Pagerluyung monitoring point had the worst quality relatively compared to other monitoring point in Brantas River with exceeding copper, lead and tin compared to the stream standard in East Java Provincial Regulation No. 2 in 2008. Brantas River was categorized as lightly polluted river based on monitoring period 2011-2015 in 5 monitoring points, namely Pendem, Sengguruh, Kademangan, Meritjan and Kertosono.

2002-01-01

We investigated the degree of Japan's contribution to the nuclear medical research in the last decade. Articles published in 1991-2000 in highly reputed nuclear medical journals were accessed through the MEDLINE database. The number of articles having affiliation with a Japanese institution was counted along with publication year. In addition, shares of top-ranking countries were determined along with their trends over time. Of the total number of articles (7,788), Japan's share of articles in selected nuclear medical journals was 11.4% (889 articles) and ranked 2nd in the world after the USA (2,645 articles). The recent increase in the share was statistically significant for Japan (p=0.02, test for trend). Japan's share in nuclear medical research output is much higher than that in other biomedical fields. (author)

Japan-U.S. cooperation in transport of plutonium

International Nuclear Information System (INIS)

Takeda, Yu

2012-01-01

Japan's effort to utilize plutonium for peaceful purpose since 1950s was caught in a cross fire after the end of the Cold War. Maritime transport of plutonium from France to Japan in 1993, for instance, was criticized by U.S. Congress, nonproliferation specialists and environmental activists. U.S. government, however, compiled with Japan-US Nuclear Cooperation Agreement and cooperated to ship plutonium. This paper focuses on why Washington was supportive for the sealift of plutonium despite of opposition against it. By solving the puzzle, this research will contribute to studies of Japan's plutonium policy and Japan-U.S. nuclear relations. Based on newspaper articles, memoirs and official documents, this paper examines backgrounds and features of controversy surrounding the transport. The analyses show the causes of U.S. cooperation to the transport, such as Japan's efforts toward nuclear nonproliferation. (author)

We investigated the effects of natural environments and human activity on Lake Biwa, central Japan. We determined the concentrations of 19 elements and the compositions of stable S and Sr isotopes in the main tributaries of the lake and compared them with the corresponding values obtained from the lake water during the circulation period. Results of a principal component analysis indicated that the components dissolved in the lower reaches of the tributaries can be divided into group 1 (HCO 3 , SO 4 , NO 3 , Ca, Mg, Sr) and group 2 components (Cl, Br, Na, K, Ba, Rb, Cs). The concentrations of group 1 components were high in the rivers of the southern area, which is urbanized and densely populated, and the eastern area, which consists of plains where agriculture predominates, compared with the rivers of the northern and western areas, which are mostly mountainous and sparsely populated. The concentrations of group 2 components tended to be high in the river water of industrial areas. The δ 34 S values of SO 4 in the river water converged to 0 ± 2 per mille as the SO 4 concentration increased and, excluding the areas where limestone is extensively distributed, as the HCO 3 concentration increased. In particular, both the δ 34 S values (0 ± 2 per mille ) and the 87 Sr/ 86 Sr ratios (0.7117 ± 0.0005) fell within narrow ranges in the small and medium rivers of the eastern plain area, where rice is widely grown. These values agreed respectively with the δ 34 S values of the fertilizers used in the Lake Biwa basin and the soil-exchangeable 87 Sr/ 86 Sr in the eastern plain. The characteristics of water quality in the small and medium rivers of the eastern area can be explained by a model in which sulfuric, nitric, and bicarbonic acids generated by the decomposition of agricultural fertilizer and paddy rice selectively leached out alkaline-earth elements adsorbed on the soil and sediments of the plain or dissolved calcium carbonate enriched with Mg and Sr. Compared

Japan and atomic co-operation

International Nuclear Information System (INIS)

1965-01-01

Japan, which is host country for the Ninth Regular Session of the Agency General Conference, has an important programme of nuclear power development to meet future needs. In addition, Japan is active in other applications of atomic energy and is building up a domestic nuclear engineering industry. Japan has profited by the Agency as a channel of international cooperation, and was a party to the first bilateral agreement in which the responsibility for administering safeguards against the diversion of materials to military purposes, was transferred to the Agency. Japan has also lent support to Agency programmes by gifts, training courses, research, and the loan of experts. In 1961, the Japan Atomic Energy Commission (AEC) formulated the 'Long-Range Programme for Development and Utilization of Atomic Energy', on the basis of the economic prospects of nuclear power generation, and the conditions necessary to meet the ever-increasing domestic energy demands. According to this programme, in the light of power reactor development trends overseas, it is expected that nuclear power costs will compete with those of oil burning stations by 1970. On this basis, total nuclear power generating capacity of 1000 MW(e) will be attained by 1970, and 7000 - 9 500M(e) by 1980. As a prelude to the above programme the Japan Atomic Power Company (JAPCO) began construction in 1959 of a graphite-moderated gas-cooled nuclear power station (Improved Calder Hall type) of 165 MW(e) gross capacity. This is now progressing smoothly, and reached criticality in May 1965; it is expected to supply commercial power by the end of this year. The second nuclear power station will be built by the same company on the coast of the Japan Sea, with a light water-moderated reactor of 250 - 300 MW(e) capacity. The construction plan i s currently being pushed forward for completion in 1970. Thereafter three private utility companies - Tokyo, Kansai and Chubu Electric Companies - are doing preparatory work for

Japan/India. Towards a nuclear cooperation?

International Nuclear Information System (INIS)

Pajon, Celine

2011-10-01

As diplomatic, economic and strategic relationships between Japan and India have been intensively developed for a decade, the author aims at discussing the very sensitive approach to a nuclear cooperation between these two countries as Japan, while taking benefit of the American nuclear umbrella, is a strong defender of nuclear disarmament and non proliferation, and India has been developing its own civilian and military nuclear programme outside of the international regime which it considers as discriminative. The author first discusses factors which incited Japan to build up a strategic partnership with India in front of the evolution of the political context, of the powerful upswing of China, and of the new American orientation with respect to Delhi. She comments the economic and political stakes of the currently negotiated Japan-India nuclear cooperation agreement which not only concerns the relationships between these both countries, but also French and American industrial groups which are present on the Indian market. She also notices that the Fukushima accident which has put Japan energy choices into question again, is a new deal which is to be taken into account

Reconceptualizing Mujō: A Japanese worldview not in the pursuit of eternity

Directory of Open Access Journals (Sweden)

A. Rezaee

2017-09-01

Full Text Available This paper discusses the concept of "Mujō," one of the fundamental concepts of Japanese culture and thinking. The concept of Mujō, compared with other concepts and keywords necessary to understand Japanese culture, is completely unknown in Iran. In fact, this concept is a prerequisite for understanding many aspects of Japanese culture. Some of these aspects include the importance of sakura or cherry blossoms in Japanese culture, the reason for the preference of wood over stone in Japanese architecture, the justification for the tradition of samurai suicide by sword, the kamikaze concept, and the specificity of the meaning of the word for goodbye (sayonara. Mujō is also instrumental in understanding the theme of many Japanese poems, particularly Haiku. Mujō represents a kind of worldview that has emerged throughout the history of Japan and through the integration of genuine Japanese thoughts with the thoughts of Buddhism. After explaining the literal and conceptual meaning of Mujō, the present article deals with its manifestations in the literature, culture, society, and language of Japan. This article also attempts, from the perspective of a non-Japanese, to examine one aspect of the Japanese worldview. Based on the various interpretations of Mujō, the author has attempted to reconceptualize Mujō by interpreting it as "escape from eternity." The present article seeks to respond to the implications of this conceptualization.

Comparative modeling analyses of Cs-137 fate in the rivers impacted by Chernobyl and Fukushima accidents

Energy Technology Data Exchange (ETDEWEB)

2014-07-01

The consequences of two largest nuclear accidents of the last decades - at Chernobyl Nuclear Power Plant (ChNPP) (1986) and at Fukushima Daiichi NPP (FDNPP) (2011) clearly demonstrated that radioactive contamination of water bodies in vicinity of NPP and on the waterways from it, e.g., river- reservoir water after Chernobyl accident and rivers and coastal marine waters after Fukushima accident, in the both cases have been one of the main sources of the public concerns on the accident consequences. The higher weight of water contamination in public perception of the accidents consequences in comparison with the real fraction of doses via aquatic pathways in comparison with other dose components is a specificity of public perception of environmental contamination. This psychological phenomenon that was confirmed after these accidents provides supplementary arguments that the reliable simulation and prediction of the radionuclide dynamics in water and sediments is important part of the post-accidental radioecological research. The purpose of the research is to use the experience of the modeling activities f conducted for the past more than 25 years within the Chernobyl affected Pripyat River and Dnieper River watershed as also data of the new monitoring studies in Japan of Abukuma River (largest in the region - the watershed area is 5400 km{sup 2}), Kuchibuto River, Uta River, Niita River, Natsui River, Same River, as also of the studies on the specific of the 'water-sediment' {sup 137}Cs exchanges in this area to refine the 1-D model RIVTOX and 2-D model COASTOX for the increasing of the predictive power of the modeling technologies. The results of the modeling studies are applied for more accurate prediction of water/sediment radionuclide contamination of rivers and reservoirs in the Fukushima Prefecture and for the comparative analyses of the efficiency of the of the post -accidental measures to diminish the contamination of the water bodies.

Neurosurgeons in Japan Are Exclusively Brain Surgeons.

Science.gov (United States)

Asamoto, Shunji

2017-03-01

In Japan, neurosurgeons have traditionally mainly treated brain diseases, with most cases involving the spine and spinal diseases historically being treated by orthopedists. Nowadays, spinal surgery is 1 of the many subspecialties in the neurosurgical field in Japan. Most patients with neurological deficits or suspected neurological diseases see board-certified neurosurgeons directly in Japan, not through referrals from family physicians or specialists in other fields. Problems originating in the spine and spinal cord have been overlooked or misdiagnosed in these situations. Neurosurgeons in Japan must rethink the educational program to include advanced trauma life support and spinal surgery. Copyright © 2016. Published by Elsevier Inc.

Anon.

2000-01-01

Since three Laws on the nuclear power were published 45 years has passed. Now, development on nuclear power in Japan is at an emergent state. In Japan, 51 units of commercial nuclear reactors with 44.917 GW are in operation, occupy about 37% of total electric power generation, and is positioned at an essential basic energy source supporting economical society in Japan. However, an accident occurred at Tokai Works of the JCO Co., Ltd., one of the uranium reconversion company, on September 30, 1999, was the first critical accident in Japan, and became the worst case in history on development of nuclear power in Japan, because of forming three heavy radiation disabled persons (One of them was dead) in its operators. This was a big crisis with relation to existence on development of nuclear power in Japan, by which anxiety and distrust of the Japanese against the nuclear power were amplified rapidly. On the other side, for Japan short in energy sources and of a big energy consumption, in order to intend for a long term to carry out energy security, global environmental conservation, and sustainable maintenance of essential growth, it remains to be one of important optional methods to further promote nuclear power generation and to establish nuclear fuel cycle. Here were described on progress on peaceful applications of nuclear power in Japan, progress on the field of nuclear power in Japan (from 1955 to 1999), progress on Tokai nuclear power station, introduction of nuclear power generation and effort on its domestic production.

River-corridor habitat dynamics, Lower Missouri River

Science.gov (United States)

Jacobson, Robert B.

2010-01-01

Intensive management of the Missouri River for navigation, flood control, and power generation has resulted in substantial physical changes to the river corridor. Historically, the Missouri River was characterized by a shifting, multithread channel and abundant unvegetated sandbars. The shifting channel provided a wide variety of hydraulic environments and large areas of connected and unconnected off-channel water bodies.Beginning in the early 1800s and continuing to the present, the channel of the Lower Missouri River (downstream from Sioux City, Iowa) has been trained into a fast, deep, single-thread channel to stabilize banks and maintain commercial navigation. Wing dikes now concentrate the flow, and revetments and levees keep the channel in place and disconnect it from the flood plain. In addition, reservoir regulation of the Missouri River upstream of Yankton, South Dakota, has substantially changed the annual hydrograph, sediment loads, temperature regime, and nutrient budgets.While changes to the Missouri River have resulted in broad social and economic benefits, they have also been associated with loss of river-corridor habitats and diminished populations of native fish and wildlife species. Today, Missouri River stakeholders are seeking ways to restore some natural ecosystem benefits of the Lower Missouri River without compromising traditional economic uses of the river and flood plain.

Universal varicella vaccine immunization in Japan.

Science.gov (United States)

Yoshikawa, Tetsushi; Kawamura, Yoshiki; Ohashi, Masahiro

2016-04-07

In 1974, Japanese scientists developed a live attenuated varicella vaccine based on the Oka strain. The efficacy of the vaccine for the prevention of varicella has been primarily demonstrated in studies conducted in the United States following the adoption of universal immunization using the Oka strain varicella vaccine in 1996. Although the vaccine was developed by Japanese scientists, until recently, the vaccine has been administered on a voluntary basis in Japan resulting in a vaccine coverage rate of approximately 40%. Therefore, Japan initiated universal immunization using the Oka strain varicella vaccine in November 2014. Given the transition from voluntary to universal immunization in Japan, it will also be important to monitor the epidemiology of varicella and herpes zoster. The efficacy and safety of co-administration of the varicella vaccine and measles, mumps, and rubella vaccine have been demonstrated in many countries; however, there was no data from Japan. In order to adopt the practice of universal immunization using the Oka strain varicella vaccine in Japan, data demonstrating the efficacy and safety of co-administration of varicella vaccine and measles and rubella (MR) vaccine were required. Additionally, we needed to elucidate the appropriate time interval between the first and second administrations of the vaccine. It is also important to differentiate between wild type and Oka vaccine type strains in herpes zoster patient with past history of varicella vaccine. Thus, there are many factors to consider regarding the adoption of universal immunization in Japan to control varicella zoster virus (VZV) infections. Copyright © 2016 Elsevier Ltd.

From sword to chrysanthemum: Japan's culture of anti-miltarism

International Nuclear Information System (INIS)

Berger, T.U.

1993-01-01

The end of the Cold War and the phenomenal increase in Japan's economic and technological power put Japan today in the position to become, if it chooses, a military as well as economic superpower. The diminution of the Soviet threat and the increasing US preoccupation with domestic problems give Japan a latitude for independent action it has not had since the end of World War II. At the same time the US-Japanese security alliance, which has enabled Japan to adopt a minimalist approach to defense and national security, is being weakened by ideologically charged trade and other economic frictions and a growing American perception of Japan as a threat to its interests. Moreover, in the long run Japan faces the prospect of having to deal with other rising regional powers, most notably the People's Republic of China. This changing international security environment thus raises question whether Japan, having become an economic rival of the United States, may not in the future become a military competitor as well; whether, after having adopted a pacifist stance for half a century, Japan may choose to unsheathe its sword once again

New Perspectives on the Climatic Impact of the 1600 Eruption of Huaynaputina Volcano, Peru

Science.gov (United States)

Verosub, K. L.; Lippman, J.

2007-05-01

A critical test of the new understanding of volcanic aerosols developed since 1982 is to determine if it can predict the effects of larger eruptions than those that have occurred since El Chichon. To do that, requires detailed information about the effects of specific large eruptions. We have been investigating the human and climatic impacts of the 1600 eruption of Huaynaputina volcano in Peru. The estimated Volcanic Explosivity Index for this eruption is 6, which is comparable to that of the 1815 eruption of Tambora volcano in Indonesia, which produced global cooling and led to crop failures, famine and social unrest. On the basis of tree-ring data, Briffa et al. (1998) suggested that the most severe short-term Northern Hemisphere cooling event of the past 600 years occurred in 1601, the year following the Huaynaputina eruption. In order gain a better understanding of the nature and extent of this cooling, we have been collecting annual time series that provide information about climatic conditions during time intervals that bracket the Huaynaputina eruption. Among the time series that we have examined (or plan to examine) are ice conditions in the harbors of Tallinn, Estonia, and Riga, Latvia and in Lake Suwa in Japan: cherry blossom blooming (sakura) dates from Kyoto, Japan; records of agricultural production from China and Russia; tithe records from the Spanish colonial empire; dates of the beginning of the wine harvest in France and the rye harvest in Sweden; prices of agricultural commodities in Europe; and river flows from the Nile and the Colorado. Often, in the records we have examined, 1601 shows up as one of the coldest years, if not the coldest year. In addition, the worst famines in Russian history took place between 1601 and 1603, which eventually led to the overthrow of Tsar Boris Gudonov. Thus, there is considerable evidence that the climatic impacts of the Huaynaputina eruption were comparable to those from the Tambora eruption. This result is

The fate of arsenic in a river acidified by volcanic activity and an acid thermal water and sedimentation mechanism.

2014-01-01

The Shozu-gawa river, located in the Aomori Prefecture, northern Japan, is affected by volcanic activities and acid thermal waters. The river is unique because both solid arsenic (As; as orpiment, As2S3) and dissolved As are supplied to the river from the uppermost caldera lake (Usori-ko Lake) and thermal ponds. The watershed is an excellent site for investigating the fate of different As species in a fluvial system. Upstream sediments near the caldera lake and geothermal ponds are highly contaminated by orpiment. This solid phase is transported as far as the mouth of the river. On the other hand, dissolved As is removed from the river system by hydrous ferric oxides (HFOs); however, HFO formation and removal of dissolved As do not occur in the uppermost area of the watershed, resulting in further downstream transport of dissolved As. Consequently, upstream river sediments are enriched in orpiment, whereas As(v), which is associated with HFOs in river sediments, increases downstream. Furthermore, orpiment particles are larger, and possibly heavier, than those of HFO with sorbed As. Fractionation between different chemical states of As during transport in the Shozu-gawa river is facilitated not only by chemical processes (i.e., sorption of dissolved As by HFOs), but also by physical factors (i.e., gravity). In contrast to acid mine drainage (AMD), in some areas of the Shozu-gawa river, both solid forms of As (as sulfide minerals) and dissolved As are introduced into the aquatic system. Considering that the stabilities of sulfide minerals are rather different from those of oxides and hydroxides, river sediments contacted with thermal waters possibly act as sources of As under both aerobic and anaerobic conditions.

Full Text Available In the paper, the relationship between Japan and the North Atlantic Alliance, the development of their partnership and Japan's contribution to the NATO missions throughout the world, as well as the current status that Japan has in the Alliance, are described and explained. The authors of the paper have presented and explained the models of cooperation between the two sides and the perspectives of their future relationships as well. Apart from the said, the internal political and legal transformation of Japan, directed towards the country's greater and more robust engagement in international missions, including the use of force, which has carefully been avoided in the past seven decades due to constitutional and legal limitations, is also shown in parallel with that. The underlying thesis statement of the paper reads as follows: Japan's coming closer to NATO, i.e. the strengthening of their partnership and the elimination of legal obstacles in Japan itself to the use of force in international politics, are complementary processes. In the paper, the analytical, synthetic and comparative methods are used.

This research examines the process of early capitalism in Japanese history. Generally it is thought that capitalism developed in the years leading to the Meiji Restoration. Like European models of early capitalist development in handicraft and cottage industries, Japan went through a similar process. Development of rural trade and small-scale capitalism sowed the seeds that broke feudal bonds and resulted in the mass factory system that made modern capitalist Japan.

Reconstructions of the dimensions and hydrological features of ancient fluvial channels, such as bankfull depth, bankfull width, and water discharges, have used empirical equations developed from compiled data-sets, mainly from modern meandering rivers, in various tectonic and climatic settings. However, the application of the proposed empirical equations to an ancient fluvial succession should be carefully examined with respect to the tectonic and climatic settings of the objective deposits. In this study, we developed empirical relationships among the mean bankfull channel depth, bankfull channel depth, drainage area, bankfull channel width, mean discharge, and bankfull discharge using data from 24 observation sites of modern gravelly rivers in the Kanto region, central Japan. Some of the equations among these parameters are different from those proposed by previous studies. The discrepancies are considered to reflect tectonic and climatic settings of the present river systems, which are characterized by relatively steeper valley slope, active supply of volcaniclastic sediments, and seasonal precipitation in the Kanto region. The empirical relationships derived from the present study can be applied to modern and ancient gravelly fluvial channels with multiple and alternate bars, developed in convergent margin settings under a temperate climatic condition. The developed empirical equations were applied to a transgressive gravelly fluvial succession of the Paleogene Iwaki Formation, Northeast Japan as a case study. Stratigraphic thicknesses of bar deposits were used for estimation of the bankfull channel depth. In addition, some other geomorphological and hydrological parameters were calculated using the empirical equations developed by the present study. The results indicate that the Iwaki Formation fluvial deposits were formed by a fluvial system that was represented by the dimensions and discharges of channels similar to those of the middle to lower reaches of

To examine the impacts of urbanization and industrialization on the coastal environment, and assess the effectiveness of control measures on the contamination by chlorinated paraffins (CPs) in East Asia, surface and core sediments were sampled from the urbanized coastal zones in China and Japan (i.e., Pearl River Delta (PRD), Hong Kong waters and Tokyo Bay) and analyzed for short-chain (SCCPs) and medium-chain CPs (MCCPs). Much higher concentrations of CPs were found in the industrialized PRD than in adjacent Hong Kong waters. Significant correlation between CP concentration and population density in the coastal district of Hong Kong was observed (r 2  = 0.72 for SCCPs and 0.55 for MCCPs, p chain groups within SCCPs in the PRD than in Hong Kong waters and Tokyo Bay implied the effect of industrialization. Comparison of temporal trends between Hong Kong outer harbor with Tokyo Bay shows the striking difference in historical deposition of CPs under different regulatory situations in China and Japan. For the first time, the declining CP concentrations in Tokyo Bay, Japan, attest to the effectiveness of emissions controls. Copyright © 2017 Elsevier Ltd. All rights reserved.

This study focused on the differences in the patterns of care for prostate cancer patients treated with radical external beam radiotherapy between Japan and the United States. Results from the 1999-2001 Japanese Patterns of Care Study (PCS) survey were compared with those of the 1999 PCS in the United States. In addition, the changing trends in the patterns of care between Japan and the United States were also analyzed. Patients in Japan were found to have more advanced primary disease than those in the United States, but the proportions of advanced disease have gradually decreased in Japan. The distributions of CT-based treatment planning, conformal therapy and higher doses were higher in the United States, and a drastic change in these parameters occurred in the United States, while only moderate changes occurred in Japan. These results indicate that patterns of care for prostate cancer in Japan are considerably different from those in the United States, and the changing trends in the patterns of care are also different between the two countries.

Alteration of the spatial variability of natural flow regimes has been less studied than that of the temporal variability, despite its ecological importance for river ecosystems. Here, we aimed to quantify the spatial patterns of flow regime alterations along a river network in the Sagami River, Japan, by estimating river discharge under natural and altered flow conditions. We used a distributed hydrological model, which simulates hydrological processes spatiotemporally, to estimate 20-year daily river discharge along the river network. Then, 33 hydrologic indices (i.e., Indicators of Hydrologic Alteration) were calculated from the simulated discharge to estimate the spatial patterns of their alterations. Some hydrologic indices were relatively well estimated such as the magnitude and timing of maximum flows, monthly median flows, and the frequency of low and high flow pulses. The accuracy was evaluated with correlation analysis (r > 0.4) and the Kolmogorov-Smirnov test (α = 0.05) by comparing these indices calculated from both observed and simulated discharge. The spatial patterns of the flow regime alterations varied depending on the hydrologic indices. For example, both the median flow in August and the frequency of high flow pulses were reduced by the maximum of approximately 70%, but these strongest alterations were detected at different locations (i.e., on the mainstream and the tributary, respectively). These results are likely caused by different operational purposes of multiple water control facilities. The results imply that the evaluation only at discharge gauges is insufficient to capture the alteration of the flow regime. Our findings clearly emphasize the importance of evaluating the spatial pattern of flow regime alteration on a river network where its discharge is affected by multiple water control facilities.

Organic photovoltaic energy in Japan

2007-01-01

Japan finances research programs on photovoltaic conversion since 1974. Research in this domain is one of the 11 priorities of NEDO, the agency of means of the ministry of economy, trade and industry of Japan. The search for an abatement of production costs and of an increase of cells efficiency is mentioned in NEDO's programs as soon as the beginning of the 1990's. A road map has been defined which foresees photovoltaic energy production costs equivalent to the ones of thermal conversion by 2030, i.e. 7 yen/kWh (4.4 cents of euro/kWh). The use of new materials in dye-sensitized solar cells (DSSC) or organic solar cells, and of new structures (multi-junctions) is explored to reach this objective. The organic photovoltaic technology is more particularly considered for small generation units in mobile or domestic technologies. Japan is particularly in advance in the improvement of DSSC cells efficiency, in particular in the domain of the research on solid electrolytes. Europe seems more in advance in the domain of the new generation of organic solar cells. Therefore, a complementarity may be found between Japan and French teams in the domain of organic solar cells improvement through collaboration programs. (J.S.)

Male acceptance of condoms in Japan.

Science.gov (United States)

Uchida, Y

Current surveys indicate that more than 70% of married couples in Japan use condoms as their primary contraceptive method. The popularity of condoms is due to the oral contraceptive (OC) pills not being recognized as safe forms of contraception and IUDs not being legalized by the government until 1974. The history of condom use in Japan goes back to 1872 when condoms of thin leather were imported into Japan from England and France. Manufacturing of condoms in Japan began in 1909, mainly as a method for venereal disease prevention. The condom and induced abortion are now the major methods of contraception. 60% of the distribution of condoms is through pharmacies and cosmetic stores; 50% of the buyers are women. Since 1955, teams of family planning workers have distributed condoms by selling on a door-to-door basis, especially to lower middle class couples. Between 1969-75, 75% of contraceptive users were using condoms. Currently there are 81% users. The rhythm method ranks second in popularity at 30% between 1969-75. OCs have gradually increased recently to 3% users, but side effects have deterred people from selecting them. The proportion of IUD users has remained at a consistently low level for the past several years. Japan accounts for 1/3 of the total world production of condoms.

L-Band RFI in Japan

In recent years, three instruments have been launched into orbit with the aim of producing global maps of sea surface salinity and soil moisture using the 1400-1427 MHz band: SMOS, Aquarius and SMAP. Although this frequency band is allocated to passive measurements only, RFI (Radio-Frequency Interference) is present in the data of all three missions. On a global scale, the three sensors have observed approximately the same distribution of RFI. Japan is an important exception that has implications for the design of RFI detection algorithms. RFI in Japan is caused by a large number of emitters belonging to the same system (TV receivers) and for this reason some traditional RFI detection strategies detect little to no RFI over Japan. The study of this case has led to an improvement of the approach to detect RFI in Aquarius data.

Work to retirement in Japan is a sequential transition for the most part, and Japan permits mandatory retirement by firms at age 60. But many older people work beyond the age of 60, many more than in other industrialized countries. A number of hypotheses are examined, having to do with pensions, health, opportunity, interest in working, cultural attitudes (including the concept of ikigai), and public policy initiatives (such as employment policy and the Silver Human Resource Centers). Japan's cultural attitudes and existing policies appear to have set Japan on a unique course in considering the aging of its population. To what extent should other nations emulate Japan?

History and structure of Japan-US nuclear alliance

International Nuclear Information System (INIS)

Yoshioka, Hitoshi

2011-01-01

'Japan-US nuclear alliance' for civil use of nuclear energy was used here as technical term for the state Japanese commercial power plants were all water-cooled reactors under the US nuclear engineering umbrella and US admitted Japanese development of all 'SNT: sensitive nuclear technology' in the area of nuclear fuel cycle. 'Japan-US alliance' was used for various areas closely related with national security while 'Japan-US nuclear weapon alliance' was for military use of nuclear energy such as nuclear weapon (transport methods included) and counter weapon system. Military and civil use of nuclear energy relied fundamentally on common technical bases and especially nuclear fuel cycle related technologies were directly connected to both uses and called 'SNT'. Japanese nuclear policy sticking to SNT might come from the axiom: nuclear engineering for national security, that meant Japan refrained from nuclear arms but maintained technical and industrial potential of nuclear arms. This could be called 'nuclear arms standby strategy' and derived from compromise of both countries to play role of stabilizer of 'Japan-US alliance'. History of Japanese nuclear power development could be well understood as formation process of 'Japan-US nuclear alliance'. If Fukushima Daiichi accident forced nuclear power to phase out, nuclear fuel cycle would be obliged to terminate. This meant failure of the axiom and dissolution of 'Japan-US nuclear alliance'. (T.

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

Since 2010, International Atomic Energy Agency (IAEA) has held the 'Nuclear Energy Management School' so-called 'IAEA-NEM' to develop future leaders who plan and manage nuclear energy utilization in their county. Since 2012, Japan Atomic Energy Agency (JAEA) together with the Japan Nuclear Human Resource Development Network (JN-HRD Net), the University of Tokyo (UT), the Japan Atomic Industrial Forum (JAIF) and JAIF International Cooperation Center (JICC) have cohosted the NEM school in Japan in cooperation with IAEA. Since then, the school has been held every year, with the school in 2016 marking the fifth. In the 2016 NEM school, Japanese nuclear energy technology and experience, such as lessons learned from the Fukushima Daiichi Nuclear Power Station accident, were provided by not only lectures by IAEA experts, but also lectures by Japanese experts and leaders in order to offer a unique opportunity for the participants from other countries to learn about particular cases in Japan. Opportunities to visit a variety of nuclear facilities were offered for the participants in the form of technical tours in Fukui and Kobe. Through the school, we contributed to the internationalization of Japanese young nuclear professionals, development of nuclear human resource of other countries including nuclear newcomers, and enhanced cooperative relationship between IAEA and Japan. Additionally, collaborative relationship with JN-HRD Net was strengthened solidly through the integrated cooperation among ministries, universities, manufacturers and research organizations across the county by holding the school in Japan. In this report, findings obtained during the preparatory work and the school period were reported in order to make a valuable contribution towards effectively and efficiently conducting future international nuclear human resource development activities in Japan.

2012/13 abnormal cold winter in Japan associated with Large-scale Atmospheric Circulation and Local Sea Surface Temperature over the Sea of Japan

Ando, Y.; Ogi, M.; Tachibana, Y.

2013-12-01

On Japan, wintertime cold wave has social, economic, psychological and political impacts because of the lack of atomic power stations in the era of post Fukushima world. The colder winter is the more electricity is needed. Wintertime weather of Japan and its prediction has come under the world spotlight. The winter of 2012/13 in Japan was abnormally cold, and such a cold winter has persisted for 3 years. Wintertime climate of Japan is governed by some dominant modes of the large-scale atmospheric circulations. Yasunaka and Hanawa (2008) demonstrated that the two dominant modes - Arctic Oscillation (AO) and Western Pacific (WP) pattern - account for about 65% of the interannual variation of the wintertime mean surface air temperature of Japan. A negative AO brings about cold winter in Japan. In addition, a negative WP also brings about cold winter in Japan. Looking back to the winter of 2012/13, both the negative AO and negative WP continued from October through December. If the previous studies were correct, it would have been extremely very cold from October through December. In fact, in December, in accordance with previous studies, it was colder than normal. Contrary to the expectation, in October and November, it was, however, warmer than normal. This discrepancy signifies that an additional hidden circumstance that heats Japan overwhelms these large-scale atmospheric circulations that cool Japan. In this study, we therefore seek an additional cause of wintertime climate of Japan particularly focusing 2012 as well as the AO and WP. We found that anomalously warm oceanic temperature surrounding Japan overwhelmed influences of the AO or WP. Unlike the inland climate, the island climate can be strongly influenced by surrounding ocean temperature, suggesting that large-scale atmospheric patterns alone do not determine the climate of islands.

This burden is felt not only by patients themselves, but also by their families and health care systems. Although the societal burden caused by this disorder has been evaluated in several countries, the magnitude of the societal cost of schizophrenia in Japan has never been estimated. The aim of this study is to clarify the societal burden of schizophrenia by estimating the cost of schizophrenia in Japan in 2008. Methods: A human capital approach was adopted to estimate the cost of schizophrenia. The total cost of schizophrenia was calculated as the sum of the direct, morbidity, and mortality costs. Schizophrenia was defined as disorders coded as F20.0–F20.9 according to the International Classification of Diseases-10. The data required to estimate the total cost was collected from publicly available statistics or previously reported studies. Results: The total cost of schizophrenia in Japan in 2008 was JPY 2.77 trillion (USD 23.8 billion. While the direct cost was JPY 0.770 trillion (USD 6.59 billion, the morbidity and mortality costs were JPY 1.85 trillion (USD 15.8 billion and JPY 0.155 trillion (USD 1.33 billion, respectively. Conclusion: The societal burden caused by schizophrenia is tremendous in Japan, similar to that in other developed countries where published data exist. Compared with other disorders, such as depression or anxiety disorders

Forms of trace arsenic, cesium, cadmium, and lead transported into river water for the irrigation of Japanese paddy rice fields

In this study, we focus on the behavior of geogenic, toxic trace elements, particularly As, Cs, Cd, and Pb, during their transportation in two rivers for irrigation commonly used in monsoon Asia; one river originates from an active volcano, Mt. Asama, and the other originates from a currently inactive volcano, Yatsugatake Mountains in Nagano, Japan. These rivers were investigated to understand the role of river water as a pollutant of rice and other aquatic plants (via irrigation) and aquatic animals. The results indicated that the behavior of toxic trace elements in river water are likely controlled by their interactions with particulate Fe, Al, and Ti compounds. The majority of Pb and Cd is transported as particulate matter with Fe, Al, and Ti, while the majority of As is transported in the dissolved form, predominantly as arsenate, with low abundance of particulate matter. Cs is transported either as the dissolved form or as particulate matter in both rivers. The investigated elements are transported in the rivers as particulate and dissolved forms, and the ratio of these forms is controlled by the pH and presence of particulate Fe, Al, and Ti phases in the river water. With respect to Cs in both rivers, the parameter governing the concentration and transportation of Cs, in the bimodal form (i.e., particulate and dissolved forms), through the river possibly shifts from sorption to pH by particulate Fe-Al-Ti, according to the abrupt increase in the concentration of Cs in the river. The chemical attraction of particulate Fe-Al-Ti for Cs is weaker than that for Pb and Cd, indicating that the lower electronegativity of Cs weakens the chemical attraction on a colloid for the competitive sorption with the other trace elements. The different relationships between As and Fe in the river and in the irrigation water and soil water, as well as those in paddy rice, suggested that As in paddy rice is not directly derived from As in the irrigation water from the river under

Japan has responded to IAEA requirements on reinforced safeguard regulations. The IAEA additional protocol entered in force in Japan on December 1999. Japan submitted a preliminary information report to IAEA on June 2000 after joint works with the Nuclear Material Control Center (NMCC) of Japan. The first annual report was submitted to IAEA on May 2001. Another activity for the additional protocol is complementary accesses. The total 36 accesses to facilities have been done from November 2000 to September 2001. Procedures of access to managements are under discussion. MEXT (Ministry of Education, Culture, Sports, Science and Technology) has been constructing the Rokkasho Safeguards On-Site Laboratory from 1997, and the Rokkasho Safeguards Center from 2000. The Design Information Verification (DIV) is now ongoing. Much more personal resources will be needed for future inspections. Therefore, the budget for safeguards is increasing in contrast to the flat base budget for the total atomic energy. As for future activity, a MOX (Mixed Oxide Fuels) fuel processing plant is one of the issues for discussion. The construction of the MOX processing plant is supposed to begin on around 2004. The conclusion of additional protocol will be given by IAEA until end of 2002. Shift to integrated safeguards are under discussions by MEXT, NMCC and utilities of Japan parallel with IAEA. Key issues of discussion are cost saving for safeguards, development of personal resources for inspectors and the role of NMCC. (Y. Tanaka)

Genetic divergence in nuclear genomes between populations of Fagus crenata along the Japan Sea and Pacific sides of Japan.

Hiraoka, Koichi; Tomaru, Nobuhiro

2009-05-01

Genetic diversity and structure in Fagus crenata were studied by analyzing 14 nuclear microsatellite loci in 23 populations distributed throughout the species' range. Although population differentiation was very low (F (ST) = 0.027; R (ST) = 0.041), both neighbor-joining tree and Bayesian clustering analyses provided clear evidence of genetic divergence between populations along the Japan Sea (Japan Sea lineage) and Pacific (Pacific lineage) sides of Japan, indicating that physical barriers to migration and gene flow, notably the mountain ranges separating the populations along the Japan Sea and Pacific sides, have promoted genetic divergence between these populations. The two lineages of the nuclear genome are generally consistent with those of the chloroplast genome detected in a previous study, with several discrepancies between the two genomes. Within-population genetic diversity was generally very high (average H (E) = 0.839), but decreased in a clinal fashion from southwest to northeast, largely among populations of the Japan Sea lineage. This geographical gradient may have resulted from the late-glacial and postglacial recolonization to the northeast, which led to a loss of within-population genetic diversity due to cumulative founder effects.

Tritium surveillance around nuclear facilities in Japan

International Nuclear Information System (INIS)

Inoue, Y.; Kasida, Y.

1978-01-01

In order to measure the tritium levels in the environmental water around the nuclear facilities, the tritium surveillance program began in 1967 locally at Tsuruga and Mihama districts. Nowadays it has been expanded to the ten commercial nuclear power stations and three nuclear facilities. For samples whose tritium concentration is believed less than about 100 pCi/l, they were electrolytically enriched, and then counted by the liquid scintillation counter. Some of samples believed higher than 100 pCi/l were analysed without any enrichment by the low background liquid scintillation counters, Aloka LB 600 or Aloka LB 1. The results of each station are listed in Table. The sampling points corresponding to each results are shown in Figure. Tritium from the effluent was not reflected in all the land water and the tap water around the nuclear power stations and the nuclear facilities. Tritium concentration in rivers, streams, and reservoirs (pools) decreased exponentially from about 600 pCi/l in 1967 to about 150 pCi/l in 1972 at Tsuruga and Mihama, and 360 pCi/l in 1968 to 120 pCi/l in 1973 at Genkai, with the half life of about 2.5 years in both cases. After around 1972, tritium levels of river system in all districts of Japan kept nearly constant up to the end of 1975 and they were in the range from 100 to 300 pCi/l corresponding to the districts. Thereafter, it seems to start to decrease again in 1976. Sea water sampled at the intake of the station or on the seashore far from the outlet was regarded not to be influenced by the effluent from the nuclear reactors or facilities. Tritium concentration in these coastal waters decreased from 100 - 300 pCi/l in 1971 to 30 - 40 pCi/l in 1972 in Fukushima, Ibaraki and Fukui prefectures. (author)

APWR - Mitsubishi, Japan/Westinghouse, USA

Aeba, Y.; Weiss, E.H.

1999-01-01

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

2012-01-01

Due to tsunami triggered by the Great East Japan Earthquake, the operating and refueling reactor facilities at Fukushima Dai-ichi and Dai-ni Nuclear Power Plants caused a nuclear hazard. Given the fact, Japanese electric power companies voluntarily began to compile various urgent measures against tsunami. And then the Nuclear and Industrial Safety Agency (NISA) ordered the licensees to put into practice the voluntarily compiled urgent safety measures, in order to ensure the effectiveness of the means for recovering cooling functions along with avoiding the release of radioactive substances to the possible minimum, even if a huge tsunami following a severe earthquake hits nuclear power plants. The following describes the state and the effect of the urgent safety measures implemented for 44 reactors (under operation) and 1 reactor (under construction) in Japan and also describes the measures to be implemented by the licensees of reactor operation in the future.

Japan was way behind western countries in nuclear power development. This is partly because of the defeat in the second world war which bound Japan to the ban on nuclear power development. As a result, Japan was obliged to take the policy of introducing the power reactor, and its technology, from overseas advanced countries in order to promote the development of power reactors for its own country.

The internationalization of Japan

International Nuclear Information System (INIS)

Kuroki, T.E.

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

Divorce in contemporary Japan.

Science.gov (United States)

Fukurai, H; Alston, J

1990-10-01

Data from the 1985-86 Japanese census are analysed to explore the determinants of the divorce rates in Japan's forty-seven prefectures, using two theoretical models: (a) the social integration model, which is shown to have a greater utility in predicting Japanese divorce levels than (b), the human capital model. Female emigration patterns play a significant role in affecting the divorce rate. Population increase and net household income are also important predictors of the Japanese divorce rate and urbanization has a great influence in modern Japan. Demographic and aggregate variables such as migration, urbanization, and socioeconomic factors are useful when organized under a social integration model.

Japan's approach to monetary policy

OpenAIRE

Giovanni P. Olivei

2002-01-01

The goal of monetary policy as conducted by the Bank of Japan is to contribute to the sound development of the national economy through the pursuit of price stability. The objective of price stability, however, is not precisely defined as it has been for other central banks. Following the implementation of the new Bank of Japan Law in 1998, the monetary policy framework is characterized by central bank independence, the primacy of the price stability objective, instrument independence, and po...

With the development of economy, the health of river ecosystem is severely threatened because of the increasing effects of human activities on river ecosystem. In this paper, the authors assessed the river ecosystem health in aspects of chemical integrity and biological integrity, using the criterion in water quality, nutrient, and benthic macroinvertebrates of 73 samples in Haihe River Basin. The research showed that the health condition of river ecosystem in Haihe River Basin was bad overall since the health situation of 72. 6% of the samples was "extremely bad". At the same time, the health situation in Haihe River Basin exhibited obvious regional gathering effect. We also found that the river water quality was closely related to human activities, and the eutrophication trend of water body was evident in Haihe River Basin. The biodiversity of the benthic animal was low and lack of clean species in the basin. The indicators such as ammonia nitrogen, total nitrogen and total phosphorus were the key factors that affected the river ecosystem health in Haihe River Basin, so the government should start to curb the deterioration of river ecosystem health by controlling these nutrients indicators. For river ecosystem health assessment, the multi-factors comprehensive evaluation method was superior to single-factor method.

Although Japan`s shipbuilding industry has been maintaining a seat for the first place in the world over 30 years or more in a contract award quantity for the new shipbuilding work, Korea got ahead of Japan and has come to be a top at the first time in 1993. Even though the various factors could be thought, it has become a turning point to be reconsidered how Japan`s shipbuilding industry should be from now on for the naval architects and persons concerned in Japan. While Japan`s production of the maritime industrial products has been in general showing the recovering tendency by a demand restoration of the large scale vessels and so forth since 1987 afterward, on the other hand, affected by an influence of the recession of the world economic activities, the total production amount in 1993 has turned to a little bit decrease and its amount was 831.8 billion yen (a ratio to the previous year: 96.4%). Though a business environment surrounding the maritime industry, in order to successively continue the work shop site inside this country as an important industry through this industry from now on, it is thought that a restoration of the price competition should be made an effort on one hand by a standardization of the maritime equipments and tools making an exclusion of the wastefulness as an object, and a strengthening of the international competitiveness at the non-price aspects such as a functionality of the products, a reliability and so forth is indispensable on the other hand. 6 figs., 3 tabs.

Change of flood risk under climate change based on Discharge Probability Index in Japan

Water-related disasters under the climate change have recently gained considerable interest, and there have been many studies referring to flood risk at the global scale (e.g. Milly et al., 2002; Hirabayashi et al., 2008). In order to build adaptive capacity, however, regional impact evaluation is needed. We thus focus on the flood risk over Japan in the present study. The output from the Regional Climate Model 20 (RCM20), which was developed by the Meteorological Research Institute, was used. The data was first compared with observed data based on Automated Meteorological Data Acquisition System and ground weather observations, and the model biases were corrected using the ratio and difference of the 20-year mean values. The bias-corrected RCM20 atmospheric data were then forced to run a land surface model and a river routing model (Yoshimura et al., 2007; Ngo-Duc, T. et al. 2007) to simulate river discharge during 1981-2000, 2031-2050, and 2081-2100. Simulated river discharge was converted to Discharge Probability Index (DPI), which was proposed by Yoshimura et al based on a statistical approach. The bias and uncertainty of the models are already taken into account in the concept of DPI, so that DPI serves as a good indicator of flood risk. We estimated the statistical parameters for DPI using the river discharge for 1981-2000 with an assumption that the parameters stay the same in the different climate periods. We then evaluated the occurrence of flood events corresponding to DPI categories in each 20 years and averaged them in 9 regions. The results indicate that low DPI flood events (return period of 2 years) will become more frequent in 2031-2050 and high DPI flood events (return period of 200 years) will become more frequent in 2081-2100 compared with the period of 1981-2000, though average precipitation will become larger during 2031-2050 than during 2081-2100 in most regions. It reflects the increased extreme precipitation during 2081-2100.

As an important composition component of river ecosystems, river habitats must undergo quality assessment to potentially provide scientific basis for river ecological restoration. Substrate composition, habitat complexity, bank erosion degree, river meandering degree, human activity intensity, vegetation buffer width, water quality, and water condition were determined as indicators for river habitat assessment. The comprehensive habitat quality index (CHQI) was established for the Wei River Basin. In addition, the indicator values were determined on the basis of a field investigation at 12 national hydrological stations distributed across the Wei, Jing, and Beiluo Rivers. The analytic hierarchy process was used to determine the indicator weights and thus distinguish the relative importance of the assessment indicator system. Results indicated that the average CHQIs for the Wei, Jing, and Beiluo Rivers were 0.417, 0.508, and 0.304, respectively. The river habitat quality for the three rivers was well. As for the whole river basin, the river habitat quality for 25% of the cross section was very well, the other 25% was well, and the 50% remaining was in critical state. The river habitat quality of the Jing River was better than that of the Wei and Beiluo Rivers.

The Great East Japan Earthquake on March 11, 2011 has catastrophic impacts on Japan. Japan is currently on the way to recovery. However, as the damage on the country as well as society is so serious, Japanese society is urged to change some systems including hazard management, energy policy, information systems and city planning. These changes are accompanied with social group realignments, thus necessarily followed by various risks. To cope with these risk issues, SRA-Japan established the special research committee for the Great East Japan Earthquake. The aim of the committee is, from viewpoints of risk analysts, to create and relate messages about risk issues in 2-3 years, in ten years and in thirty years from the earthquake. To do this, the committee garners SRA-Japan member's opinions about possible risks in Japan by using Delphi method. In SRA-Japan, there are over 600 members in interdisciplinary fields from various backgrounds, thus the messages are expected to be helpful for Japanese society to lower its risks and to optimize the resource allocation. The research is now underway. An interim report will be presented. (author)

1983-11-01

The position of black coal in the energy balance of Japan is discussed. About 75% of electric energy is produced by thermal power plants. Eighty-five per cent of electricity is produced by power plants fired with liquid fuels and 3% by coal fired plants. Coal production in Japan, the forecast coal import to the country by 1990 (132 Mt/year), proportion of coal imported from various countries, chemical and physical properties of coal from Australia, China and Japan are discussed. Coal classification used in Japan is evaluated. The following topics associated with coal combustion in fossil-fuel power plants in Japan are discussed: coal grindability, types of pulverizing systems, slagging properties of boiler fuel in Japan, systems for slag removal, main types of steam boilers and coal fired furnaces, burner arrangement and design, air pollution control from fly ash, sulfur oxides and nitrogen oxides, utilization of fly ash for cement production, methods for removal of nitrogen oxides from flue gas using ammonia and catalysts or ammonia without catalysts, efficiency of nitrogen oxide control, abatement of nitrogen oxide emission from boilers by flue gas recirculation and reducing combustion temperatures. The results of research into air pollution control carried out by the Nagasaki Technical Institute are reviewed.

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

Policymakers working to introduce and promote the use of bioenergy in Japan require detailed information on the scales of the different types of biomass resources generated. In this research, the first of its type in Japan, the investigators reviewed various statistical resources to quantify the scale distribution of forest residues, waste wood from manufacturing, waste wood from construction, cattle manure, sewage sludge, night soil, household garbage, and waste food oil. As a result, the scale of biomass generation in Japan was found to be relatively small, on the average is no more than several tons in dry weight per day. (author)

Entomological journals and publishing in Japan.

Science.gov (United States)

Fukatsu, Takema

Here I present an overview of entomological journals and publishing in Japan, thereby providing a convenient portal to the valuable scientific resources for the world's entomological researchers and scientific communities. Currently, except for several international journals published fully in English such as Applied Entomology and Zoology and Entomological Science , many entomological and entomology-related journals in Japan are not indexed by major scientific databases like Web of Science, and therefore they are neither conveniently recognizable nor accessible for the world's entomological communities. However, I point out that many of the contents of such journals are freely available via Japan's public platforms for electronic scientific literature, Japan Science and Technology Information Aggregator, Electronic (J-stage) or Citation Information by National Institute of Informatics (CiNii). Here I list 32 entomological and entomology-related societies and their 45 journals, the majority of which belong to either the Union of Japanese Societies for Insect Sciences (UJSIS), the Union of the Japanese Societies for Systematic Biology (UJSSB), the Union of Japanese Societies for Natural History (UJSNH), or the Union of Japanese Societies for Biological Science (UJSBS), with their respective URL and open-access availability.

Japan, new agenda for energy security

International Nuclear Information System (INIS)

Chrisstoffels, J.H.

2007-07-01

The author argues that the Japanese government will actively seek to strengthen security of supply. Japan has almost no domestic energy reserves. It is Asia's leading energy importer, but it faces increasing competition for resources from China and India. This has led to growing concern among Japanese policy makers. In the spring of 2007 a new Basic Energy Law was drafted that offers a strategic change of direction, away from a policy emphasis on free (energy) trade promotion and liberalisation of domestic energy markets. Japan will boost energy diplomacy towards energy producing countries and increase financial guarantees to Japanese oil and gas development companies. At the same time, Japan will raise efforts to lower its dependency on foreign oil and gas. To this end, it has set ambitious targets for further nuclear power development and the promotion of bio-trade. The author points at a multitude of complexities that may impede the success of these policies, Still, EU policy makers should be aware that Japan's energy policy has changed, driven by the conviction that markets alone cannot be relied upon to guarantee a secure supply of energy.

Current asthma deaths among adults in Japan

Directory of Open Access Journals (Sweden)

Tsugio Nakazawa

2004-01-01

Full Text Available Recent asthma deaths were examined from yearly reports of the Ministry of Health, Labor and Welfare of Japan and from reports published by the Japan Asthma Death Investigation Committee on 811 deaths over the period 1992–2000. The rate and number of recent asthma deaths in Japan have been decreasing rapidly. Most asthma deaths were of patients aged 70–90 years and there has been a marked trend for increased asthma deaths in the elderly. As for the circumstances surrounding the deaths, sudden death, unstable sudden aggravation and intermittent aggravation were mainly noted. Respiratory infections, fatigue and stress were the major courses of fatal attacks contributing to deaths due to asthma. Many of the patients who died from asthma had been diagnosed as having as moderate to severe asthma and many had non-atopic asthma. There are some reports that suggest that the recent decrease in asthma deaths in Japan is correlated with the use of inhaled cortico- steroids.

Elementary particle theory in Japan, 1930-1960

Brown, L.M.; Kawabe, Rokuo; Konuma, Michiji; Maki, Ziro

1991-01-01

The present volume consists of the combined proceedings of two Japan-USA Collaborative Workshops, organized to explore historical developments of particle theory in Japan during the period 1930-1960, i.e., the three decades that include the birth and development of Meson Theory. The first phase of workshops was held during September 1978-July 1979 and the second during July 1984-September 1985. The original versions of these proceedings were published informally; namely, the former was distributed as a series of preprints of the Yukawa Institute (then called RIFP) entitled 'Particle Physics in Japan, 1930-50 Vol. I, II' (RIFP-407 and -408, September 1980); the latter was issued in the form of camera-ready printing from Yukawa Hall Archival Library (YHAL) in May 1988, under the title 'Elementary Particle Theory in Japan, 1935-1960'. Only a small number of copies were printed for both sets of proceedings due to financial limitations of the project. (author)

Delays in clinical development of neurological drugs in Japan.

Ikeda, Masayuki

2017-06-28

The delays in the approval and development of neurological drugs between Japan and other countries have been a major issue for patients with neurological diseases. The objective of this study was to analyze factors contributing to the delay in the launching of neurological drugs in Japan. We analyzed data from Japan and the US for the approval of 42 neurological drugs, all of which were approved earlier in the US than in Japan, and examined the potential factors that may cause the delay of their launch. Introductions of the 42 drugs in Japan occurred at a median of 87 months after introductions in the US. The mean review time of new drug applications for the 20 drugs introduced in Japan in January 2011 or later (15 months) was significantly shorter than that for the other 22 drugs introduced in Japan in December 2010 or earlier (24 months). The lag in the Japan's review time behind the US could not explain the approval delays. In the 31 of the 42 drugs, the application data package included overseas data. The mean review time of these 31 drugs (17 months) was significantly shorter than that of the other 11 drugs without overseas data (26 months). The mean approval lag behind the US of the 31 drugs (78 months) was also significantly shorter than that of the other 11 drugs (134 months). These results show that several important reforms in the Japanese drug development and approval system (e.g., inclusion of global clinical trial data) have reduced the delays in the clinical development of neurological drugs.

Superconducting magnet development in Japan

Yasukochi, K.

1983-01-01

The present state of R and D works on the superconducting magnet and its applications in Japan are presented. On electrical rotating machines, 30 MVA superconducting synchronous rotary condenser (Mitsubishi and Fuji) and 50 MVA generator are under construction. Two ways of ship propulsion by superconducting magnets are developing. A superconducting magnetically levitated and linear motor propelled train ''MAGLEV'' was developed by the Japan National Railways (JNR). The superconducting magnet development for fusion is the most active field in Japan. The Cluster Test program has been demonstrated on a 10 T Nb 3 Sn coil and the first coil of Large Coil Task in IEA collaboration has been constructed and the domestic test was completed in JAERI. These works are for the development of toroidal coils of the next generation tokamak machine. R and D works on superconducting ohmic heating coil are in progress in JAERI and ETL. The latter group has constructed 3.8 MJ pulsed coil. A high ramp rate of changing field in pulsed magnet, 200 T/s, has been tested successfully. High Energy Physics Laboratory (KEK) are conducting active works. The superconducting μ meson channel and π meson channel have been constructed and are operating successfully. KEK has also a project of big accelerator named ''TRISTAN'', which is similar to ISABELLE project of BNL. Superconducting synchrotron magnets are developed for this project. The development of superconducting three thin wall solenoid has been started. One of them, CDF, is progressing under USA-Japan collaboration

Japan's new basic energy plan

International Nuclear Information System (INIS)

Duffield, John S.; Woodall, Brian

2011-01-01

In June 2010, the Japanese cabinet adopted a new Basic Energy Plan (BEP). This was the third such plan that the government has approved since the passage of the Basic Act on Energy Policy in 2002, and it represents the most significant statement of Japanese energy policy in more than four years, since the publication of the New National Energy Strategy (NNES) in 2006. Perhaps more than its predecessors, moreover, the new plan establishes a number of ambitious targets as well as more detailed measures for achieving those targets. Among the targets are a doubling of Japan's 'energy independence ratio,' a doubling of the percentage of electricity generated by renewable sources and nuclear power, and a 30 percent reduction in energy-related CO 2 emissions, all by 2030. This paper explains the origins of the 2010 BEP and why it was adopted. It then describes the content of the plan and how it differs from the NNES. A third section analyzes the appropriateness of the new goals and targets contained in the BEP and their feasibility, finding that achievement of many of the targets was likely to be quite challenging even before the March 2011 earthquake, tsunami, and nuclear crisis. - Highlights: → Origins of Japan's new Basic Energy Plan. → Content of Japan's new Basic Energy Plan. → Feasibility of achieving the targets in Japan's new Basic Energy Plan. → Impact of 2011 earthquake and tsunami on Japanese energy policy.

Related research and development works are underway at several organizations under the discussion and coordination of the Japanese FBR R and D Steering Committee, which is composed of Power Reactor and Nuclear Fuel Development Corporation (PNC), JAPC, Japan Atomic Energy Research Institute (JAERI) and Central Research Institute of Electric Power Industry (CRIEPI). In November 1996, the Japan Atomic Energy Commission (JAEC) established a Social Gathering Meeting to discuss generally the significance of FBR development in Japan for the future. (author)

Japan's Ambivalent Diplomacy on Climate Change

International Nuclear Information System (INIS)

Pajon, C.

2010-01-01

Japan often pictures itself as an environmental leader. While many examples of Japan's actions against climate change are in line with global climate change norms, others can be in opposition to them. This study, based on first hand interviews with Japanese policy makers and actors from the private and civil society sector, gives an informed perspective on the process through which Japan came to integrate and implement, at the domestic level, the international objective of climate change prevention, pointing out the discrepancies, tensions or synergies that emerged. As the current governance on climate change, and particularly after the Copenhagen conference, tends to reassert the importance of the national level against the global one, the Japanese case can serve as an example of tools and strategies that fully integrate the domestic level

Japan is third after the USA and France in terms of the Western World's installed nuclear capacity, but it has by far the largest forward programme. Great effort is also being put into the fuel cycle and advanced reactors. There is close co-operation between the government, utilities and manufacturers, but Japan has not sought to export reactors. The government has responded to the growing public opposition to nuclear power with a massive increase in its budget for public relations. Details of the nuclear power programme are given. (author)

Japan's fuel recycling policy

International Nuclear Information System (INIS)

Anon.

1991-01-01

The Atomic Energy Commission (AEC) has formulated Japanese nuclear fuel recycling plan for the next 20 years, based on the idea that the supply and demand of plutonium should be balanced mainly through the utilization of plutonium for LWRs. The plan was approved by AEC, and is to be incorporated in the 'Long term program for development and utilization of nuclear energy' up for revision next year. The report on 'Nuclear fuel recycling in Japan' by the committee is characterized by Japanese nuclear fuel recycling plan and the supply-demand situation for plutonium, the principle of the possession of plutonium not more than the demand in conformity with nuclear nonproliferation attitude, and the establishment of a domestic fabrication system of uranium-plutonium mixed oxide fuel. The total plutonium supply up to 2010 is estimated to be about 85 t, on the other hand, the demand will be 80-90 t. The treatment of plutonium is the key to the recycling and utilization of nuclear fuel. By around 2000, the private sector will commercialize the fabrication of the MOX fuel for LWRs at the annual rate of about 100 t. Commitment to nuclear nonproliferation, future nuclear fuel recycling program in Japan, MOX fuel fabrication system in Japan and so on are reported. (K.I.)

Andreeva, Anna

2014-01-01

This paper focuses on childbirth in Japan's aristocratic households during the Heian period (794-1185). Drawing on various sources, including court diaries, visual sources, literary records, and Japan's first medical collection, with its assortment of gynaecological and obstetric prescriptions, as well as Buddhist and other ritual texts, this short excursion into the cultural history of childbirth offers an insight into how childbirth was experienced and managed in Heian Japan. In particular, it addresses the variety of ideas, knowledge systems and professionals involved in framing and supporting the process of childbirth in elite households. In so doing, it casts light on the complex background of early Japanese medicine and healthcare for women.

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

The purpose of the study was to report the prevalence of trauma exposure and PTSD, conditional risk of PTSD associated with each trauma exposure in the community population in Japan. An interview survey was conducted of a random sample of adult residents in 11 communities of Japan. Among 4134 respondents (response rate, 55%), data from those who completed the part 2 interview (n = 1682) were analyzed with a weight for this subsample. Lifetime experiences of 27 trauma events and PTSD were assessed using the WHO-Composite International Diagnostic Interview version 3.0. Sixty percent of the part 2 sample reported exposure to at least one lifetime traumatic event. Lifetime and 12-month PTSD prevalences were 1.3% and 0.7%, respectively. Percentage of all months lived with PTSD in the population was predominantly accounted for by physical/sexual assaults and having a child with serious illness, and unexpected death of loved one. Ten percent of respondents reported “private events”, for which respondents did not have to describe the content, which accounted for 19% of months with PTSD. The lower prevalence of PTSD in Japan seems attributable to lower conditional risks of PTSD following these events, as well as different distributions of the events. The greater impact of events that occurred to loved ones rather than to oneself and “private events” on PTSD in Japan warrants further research of cross-cultural assessment of trauma exposure and cultural heterogeneity in the trauma-PTSD relationship.

The cause of larger local magnitude (Mj) in western Japan

Science.gov (United States)

Kawamoto, H.; Furumura, T.

2017-12-01

The local magnitude of the Japan Meteorological Agency (JMA) scale (Mj) in Japan sometimes show a significant discrepancy between Mw. The Mj is calculated using the amplitude of the horizontal component of ground displacement recorded by seismometers with the natural period of T0=5 s using Katsumata et al. (2004). A typical example of such a discrepancy in estimating Mj was an overestimation of the 2000 Western Tottori earthquake (Mj=7.3, Mw=6.7; hereafter referred to as event T). In this study, we examined the discrepancy between Mj and Mw for recent large earthquakes occurring in Japan.We found that the most earthquakes with larger Mj (>Mw) occur in western Japan while the earthquakes in northern Japan show reasonable Mj (=Mw). To understand the cause of such larger Mj for western Japan earthquakes we examined the strong motion record from the K-NET and KiK-net network for the event T and other earthquakes for reference. The observed ground displacement record from the event T shows a distinctive Love wave packet in tangential motion with a dominant period of about T=5 s which propagates long distances without showing strong dispersions. On the other hand, the ground motions from the earthquakes in northeastern Japan do not have such surface wave packet, and attenuation of ground motion is significant. Therefore, the overestimation of the Mj for earthquakes in western Japan may be attributed to efficient generation and propagation properties of Love wave probably relating to the crustal structure of western Japan. To explain this, we then conducted a numerical simulation of seismic wave propagation using 3D sedimentary layer model (JIVSM; Koketsu et al., 2012) and the source model of the event T. The result demonstrated the efficient generation of Love wave from the shallow strike-slip source which propagates long distances in western Japan without significant dispersions. On the other hand, the generation of surface wave was not so efficient when using a

Bialous, Stella Aguinaga; Mochizuki-Kobayashi, Yumiko; Stillman, Frances

2006-04-01

For decades, the tobacco companies have developed a worldwide campaign to oppose the creation of smoke-free environments. Public health efforts to promote clean indoor air have been uneven throughout the world, and in few places have such efforts faced as many challenges as in Japan. The Japanese market is dominated by Japan Tobacco, which is partly owned by the government, and Philip Morris International is also present in Japan. Japan Tobacco and Philip Morris International have developed campaigns promoting courtesy and tolerance that, until recently, seem to have resonated well with the public. The companies also have supported research promoting ventilation and have funded consultants to act as experts in the area of second-hand smoke exposure. Japan is a critical country to study, partly because of the strength of Japan Tobacco in the country and the growth of Japan Tobacco International in Southeast Asia and the rest of the world, and partly because of Japan's ratification of the World Health Organization Framework Convention on Tobacco Control. This paper uses tobacco industry documents to provide an overview of the tobacco industry's scientific and political efforts to stifle the development of clean indoor measures in Japan. Learning past industry strategies may assist policymakers and advocates in the development of future public health activities.

Strontium isotopic ratios of Tertiary volcanic rocks of northeastern Honshu, Japan: implication for the spreading of the Japan Sea

International Nuclear Information System (INIS)

Kurasawa, Hajime; Konda, Tadashi.

1986-01-01

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

Status report of shielding investigation in Japan

International Nuclear Information System (INIS)

Shindo, M.

1964-01-01

The Japan Atomic Energy Research Institute (JAERI) was established in 1954, and immediately proceeded with the construction of a research reactor. The first symposium in Japan on nuclear energy was held in 1957. Most of the papers presented in the field of reactor shielding were limited to shielding materials and their fabrication. In the first stage of our investigations, our efforts were devoted to practical design studies of reactor shielding. As a result of these studies, it was found that the formulae at hand for calculations were inadequate, but at that time no electronic computer was available in Japan nor were theoretical calculations very actively undertaken. Problems on nuclear ship shielding had been investigated at the Ship Research Institute, since 1956 and many fruitful results had been obtained. About that time the Japan Atomic Industry Forum started activities and took the initiative in organizing shielding research. Research workers in the shipbuilding industry in particular have been seriously studying shielding problems. Few years after the first symposium, problems concerning more fundamental studies were treated by many research workers. Shielding experiments using radioisotopes were carried out and many fruitful results were obtained. They are described in the this paper. Medium size electronic computers became available in Japan, permitting a theoretical study group to make an active contribution. They produced some codes, and their results are also described in the following sections. This constituted the second stage of our investigations. A swimming-pool reactor, JRR-4 (Japan Research Reactor-4), has been under construction at JAERI since 1962 and will become critical in autumn 1964. After characteristic tests it will be a very powerful tool for the shielding investigations. This id the beginning of the third stage of investigations

Toward freedom from cancer pain in Japan.

Science.gov (United States)

Otsuka, Kuniko; Yasuhara, Hajime

2007-01-01

Life expectancy in Japan is highest in the world. Cancer is the leading cause of mortality in Japan, accounting for about 30 percent of all deaths. Many Japanese cancer patients experience severe pain although they and their families hope to be pain free at the end of their lives. Toward that end, the consumption of morphine in Japan has increased markedly since 1989. The amount of morphine hydrochloride and morphine sulfate consumed in 2001 was 6.1 times that used in Japan in 1989. However, the amount of morphine consumed in Japan is still less than in other developed nations, and was only one-sixth of the amount used in Australia in 2001. As a result, many Japanese cancer patients experience potentially manageable cancer pain, largely because the amount of the drug used by doctors is insufficient for pain control. An increasing number of Japanese doctors now understand that their patients' quality of life is most important in end-of-life care and how to use the three step analgesic ladder of the World Health Organization (WHO). However, other doctors do not understand these issues sufficiently causing some patients to die without good pain control. Both the general population and some medical professionals misunderstand and have prejudice against the use of morphine. Patients often do not participate in decision making about medical treatment because of remaining paternalism in the relationship between Japanese doctors and patients. Thus, cancer pain management in Japan is not as effective as it can be and not all Japanese cancer patients receive appropriate management for their cancer pain. To improve outcomes for Japanese patients, it is necessary for health professional and social work students and practicing professionals to receive contemporary education including an introduction to palliative care and ethics.

Reactor construction programme in Japan

1959-04-15

In September last year, the Japanese Government requested the International Atomic Energy Agency to supply three tons of natural uranium for a research reactor, and the Agency has now arranged for its sale to Japan. The metal will be supplied in ingot form and after fabrication it will be used as fuel in a reactor of the natural uranium, heavy water type. The uranium will be obtained from Canada and sold to Japan by IAEA. The Agency had invited tenders for its supply, and after considering the tenders received, the Agency's Board of Governors decided that the Canadian offer to the Agency of three tons of natural uranium free of charge should be accepted and that the selling price to Japan should be US $35. 50 per kilogramme. The price takes into account Article XIV/E of the Agency's Statute which says that the Agency shall establish a scale of charges (including those for storage and handling) for materials furnished to Member States, and that the scale shall be designed to produce revenues to meet expenses in connexion with materials acquired by the Agency and costs of materials and services provided by it under agreements with one or more members. This is the first operation of its kind to be undertaken by the Agency, and the reactor for which the supply is being made will be the first in Japan to be constructed by Japanese scientists and technicians. IAEA's Board of Governors has given the necessary approval to the reactor project for which the Agency is providing assistance

Gambling disorder is a psychiatric disorder characterized by persistent and recurrent problematic gambling behavior, associated with impaired functioning, reduced quality of life, and frequent divorce and bankruptcy. Gambling disorder is reclassified in the category Substance-Related and Addictive Disorders in the DSM-5 because its clinical features closely resemble those of substance use disorders, and gambling activates the reward system in brain in much the same way drugs do. Prevalence of gambling disorder in Japan is high rate because of slot machines and pachinko game are very popular in Japan. The author recommend group psychotherapy and self-help group (Gamblers Anonymous), because group dynamics make them accept their wrongdoings related to gambling and believe that they can enjoy their lives without gambling.

China's air pollution and Japan's response to it

International Nuclear Information System (INIS)

Matsuura, S.

1995-01-01

Long-range transport of air pollutants has been a serious global environment problem. Japan's Central Research Institute of Electric Power Industry (CRIEPI) researchers are investigating the possibility of acid rain from China. So far, the acid rain that has appeared in Japan has not had a significant effect. However, because of the high economic growth projected for the coming years in China, acidic fallout from that country is likely to cause serious damage there and in Japan as well. China is one of the largest coal users in the world. One of the biggest factors making air quality worse is the lack of appropriate technologies. Although Japanese desulfurization technologies are well advanced, they cannot be directly applied to stationary pollution sources in China, because of their cost. Japan has sophisticated technologies, but lacks experience in and knowledge of alternative, intermediate, and low-technology solutions. Given this, Japan may attempt to buy pollution control technology equipment from the United States, which provides a wider range of desulfurization technologies, as a part of the Official Development Assistance program. At the same time, international support that includes the establishment of additional global environmental monitoring stations in China are also necessary

Policy of Japan of radioactive waste management

International Nuclear Information System (INIS)

Oyama, A.

1989-01-01

Development and utilization of nuclear power has been steadily pursued in Japan in order to secure a stable source of energy over a long-term period. According to the author, nuclear power plants are operated carefully and safely and have been generating electricity for more than twenty years. In fact, it now accounts for approximately 30% of total electricity generated, and has become an integral part of the energy supply in Japan. The benefits of nuclear technology are now enjoyed not only in the electricity production, but also in the fields such as medicine and other industries. Under such circumstances, radioactive waste management generated in nuclear power plants and reprocessing plants as well as in industrial and medical uses of radiation, is an important part of the nuclear energy policy, and there is also a strong public interest in this field. The government is active in formulating waste management policies based on the basic policies indicated by Japan ATomic Energy Commission (JAEC). This presentation will touch upon the future perspective of radioactive waste management policy in Japan

There were many interesting presentations of unique studies at the Annual Meeting of the Japanese Society of Nuclear Medicine, although there were fewer attendees from Europe than expected. These presentations included research on diseases that are more frequent in Japan and Asia than in Europe, synthesis of original radiopharmaceuticals, and development of imaging devices and methods with novel ideas especially by Japanese manufacturers. In this review, we introduce recent nuclear medicine research conducted in Japan in the five categories of Oncology, Neurology, Cardiology, Radiopharmaceuticals and Technology. It is our hope that this article will encourage the participation of researchers from all over the world, in particular from Europe, in scientific meetings on nuclear medicine held in Japan. (orig.)

Getting to Grips Again with Dependency. Japan's Energy Strategy

International Nuclear Information System (INIS)

Chrisstoffels, J.H.

2007-08-01

Japan has had to deal with a high level of dependency on energy imports for many decades. Today the country faces an increasingly competitive global energy market that forces it to reinvent its traditional security of supply policies. Unfortunately for Japan, the rise of China and India is increasing the competition for scarce energy supplies among consumer countries, whereas in the past supplier countries competed for access to the attractive Japanese market. To confront the challenges of the new environment the Japanese government has drafted a New National Energy Strategy. This paper analyses the strength of the strategy's proposals and targets, in particular those aimed at improving security of oil and gas supply. To assess the impact of the strategy we place it firmly against the background of Japan's history of energy security policy, as well as Japan's recent experiences with 'strategic resource projects'. This paper finds that Japan's policies in post-1973 history have been impeded by a complex set of factors. Traditionally this set has included Japan's troubled bilateral relations with Russia and China, and Japan's security dependence on the United States. Other factors are Japan's inability to synchronise national and corporate interests, and a lack of cooperation between domestic energy companies. More recently, rising oil prices, growing resource competition with China and lacklustre domestic demand-growth for energy have increased anxiety about security of supply amongst policymakers in Tokyo. In three case studies the paper illustrates in detail how these factors - in combination or by themselves - have structurally compromised Japanese initiatives to improve security of supply. The case studies discuss the Azadegan oil development project in Iran, plans for a pan-Siberian oil pipeline, and the oil and gas projects on Russia's Sakhalin Island. Our analysis of the New National Energy Strategy confirms that energy security is back on Japan's policy

What is nuclear power in Japan?

Science.gov (United States)

Suzuki, Toshikazu

2011-03-01

The aggressive use of such non-fossil energy as the atomic energy with high power density and energy production efficiency is an indispensable choice aiming at the low-carbon society. There is a trial calculation that the carbon dioxide emission of 40000 ton can be suppressed by nuclear power generation by one ton of uranium. The basis of nuclear research after the Second World War in Japan was established by the researchers learnt in Argonne National Laboratory. In 2010, NPPs under operation are 54 units and the total electric generating power is 48.85GW. The amount of nuclear power generation per person of the people is 0.38kW in Japan, and it is near 0.34kW of the United States. However, the TMI accident and the Chernobyl disaster should have greatly stagnated the nuclear industry of Japan although it is not more serious than the United States. A lot of Japanese unconsciously associate a nuclear accident with the atomic bomb. According to the investigation which Science and Technology Agency carried out to the specialist in 1999, ``What will be the field where talent should be emphatically sent in the future?'' the rank of nuclear technology was the lowest in 32 fields. The influence of the nuclear industry stagnation was remarkable in the education. The subject related to the atomic energy of a university existed 19 in 1985 that was the previous year of the Chernobyl disaster decreased to 7 in 2003. In such a situation, we have to rely on the atomic energy because Japan depends for 96% of energy resources on import. The development of the fuel reprocessing and the fast breeder reactor has been continued in spite of a heavy failure. That is the only means left behind for Japan to be released from both fossil fuel and carbon dioxide.

Previous studies have used observed discharge at the river mouth, as well as seasonally averaged inter-annual, annual, monthly or daily simulated data. Here, we reproduced the hourly peak discharge during two typhoon events for a targeted set of nine rivers and compared their impact on SSS in the coastal zone based on observed, climatological and simulated freshwater outflows in conjunction with verification of the results using satellite remote-sensing data. We created a set of hourly simulated freshwater outflow data from nine first-class Japanese river basins flowing to the western Pacific Ocean for the two targeted typhoon events (Chataan and Roke) and used it with the integrated hydrological (CDRMV3.1.1) and oceanographic (JCOPE-T) model, to compare the case using climatological mean monthly discharges as freshwater input from rivers with the case using our hydrological model simulated discharges. By using the CDRMV model optimized with the SCE-UA method, we successfully reproduced hindcasts for peak discharges of extreme typhoon events at the river mouths and could consider multiple river basin locations. Modeled SSS results were verified by comparison with Chlorophyll-a distribution, observed by satellite remote sensing. The projection of SSS in the coastal zone became more realistic than without including extreme freshwater outflow. These results suggest that our hydrological models with optimized model parameters calibrated to the Typhoon Roke and Chataan cases can be successfully used to predict runoff values from other extreme precipitation events with similar physical characteristics. Proper simulation of extreme

Export of 134 Cs and 137 Cs in the Fukushima river systems at heavy rains by Typhoon Roke in September 2011

Directory of Open Access Journals (Sweden)

S. Nagao

Full Text Available At stations on the Natsui River and the Same River in Fukushima Prefecture, Japan, effects of a heavy rain event on radiocesium export were studied after Typhoon Roke during 21–22 September 2011, six months after the Fukushima Dai-ichi Nuclear Power Plant accident. Radioactivity of 134Cs and 137Cs in river waters was 0.009–0.098 Bq L−1 in normal flow conditions during July–September 2011, but it increased to 0.85 Bq L−1 in high flow conditions because of heavy rains occurring with the typhoon. The particulate fractions of 134Cs and 137Cs were 21–56% of total radiocesium in the normal flow condition, but were close to 100% after the typhoon. These results indicate that the pulse input of radiocesium associated with suspended particles from land to coastal ocean occurred because of the heavy rain event. Export flux of 134Cs and 137Cs attributable to the heavy rain accounts for 30–50% of the annual radiocesium flux from inland to coastal ocean region in 2011. Results show that rain events are one factor contributing to the transport and dispersion of radiocesium in river watersheds and coastal marine environments.

Role of fast breeders in Japan

International Nuclear Information System (INIS)

Oyama, A.; Tomabechi, K.

1978-09-01

To meet increasing future energy demand in Japan utilization of fission energy should be promoted. In particular it is of vital importance to develop and utilize FBRs as soon as possible in order to save the natural uranium needed. If one considers the commercial introduction of FBRs in the mid-1990s in Japan, a delay of only one year will eventually result in an additional demand for natural uranium of more than 20,000 tons, because several LWRs will have to be installed instead. Ten years have passed since the development of FBRs in Japan was initiated as a national project with the highest priority and now the experimental fast reactor JOYO is successfully being operated at 50MW and the prototype fast breeder reactor MONJU has reached the stage of proceeding to construction with a schedule of operation in the mid-1980s. Following operation of MONJU, construction of a large demonstration reactor of 1000 - 15000 MW(e) will be undertaken. Some 2 - 3 years after the construction of the demonstration reactor, a series of reactors will be constructed similar in size and design to promote commercialization of LMFBRs. Strong efforts will be made to put this programme into practice. It is expected that LMFBRs will play an important role in mitigating the serious problem of energy supply in Japan foreseeable around the turn of the century

2005-01-01

In October 2005, the Japan Atomic Energy Agency (JAEA) was established as an independent administrative institution with the integration of the Japan Atomic Energy Research Institute (JAERI) and the Japan Nuclear Cycle Development Institute (JNC). JAEA is the only institute in Japan dedicated to comprehensive research and development in the field of nuclear energy. This paper put together a special article on its role and expectation. Firstly the essentials of comprehensive nuclear research and its future perspective were discussed mainly based on 'Framework for Nuclear Energy Policy' of the Atomic Energy Commission of Japan. Eight articles were followed on specific items such as quantum beams utilization, hydrogen production with nuclear heat, neutron science and ITER project, and put stress on joint works and smooth transfer of related technology to the private sector.

Neuropsychology in Japan: history, current challenges, and future prospects.

Science.gov (United States)

Sakamoto, Maiko

2016-11-01

The purpose of this special issue was to describe the cross-cultural differences in neuropsychology throughout the world. The current state of neuropsychology in Japan is discussed in this manuscript. Information on six topics, including (1) the history of Japanese neuropsychology, (2) licensure system, (3) job opportunities, (4) neuropsychological clinical services, (5) neuropsychological tests, and (6) neuropsychological research, was gathered via literature searches, official organization websites, and personal communication with clinical psychologists and other professionals in Japan. Neuropsychology reached Japan from the west in the late 1800s, a period of rapid political and social modernization. Professional associations were founded in the 1960s and 1970s and continued to grow. The need for neuropsychological assessment in Japan is growing; however, credential requirements for neuropsychologists have not yet been established. To practice clinical psychology in Japan, one must obtain a Master's degree and pass a licensure examination that is administered by a private professional foundation. Clinical psychologists often conduct neuropsychological tests; however, they have little training in neuropsychological assessment. While many western neuropsychological tests have been translated into Japanese and are used in clinical settings, the majority of translated tests have not been standardized and their psychometric properties remain poorly understood. Standardization and development of normative data in Japan is warranted. Given that needs for neuropsychological services are increasing, it is essential for clinical psychologists in Japan to improve their skills in neuropsychological evaluations. Japanese graduate schools must work to establish neuropsychology programs to educate and train clinical neuropsychologists.

2016-11-01

Source-specific elucidation of domestic sewage pollution caused by various effluent sources in an urban river water, as conducted for this study, demands knowledge of the relation between concentrations of pharmaceuticals and personal care products (PPCPs) as molecular indicators (caffeine, carbamazepine, triclosan) and water quality concentrations of total nitrogen (T-N) and total phosphorous (T-P). River water and wastewater samples from the Asahikawa River Basin in northern Japan were analyzed using derivatization-gas chromatography/mass spectrometry. Caffeine, used as an indicator of domestic sewage in the Asahikawa River Basin, was more ubiquitous than either carbamazepine or triclosan (92-100 %). Its concentration was higher than any target compound used to assess the basin: caffeine, caffeine concentrations detected in wastewater effluents and the strongly positive mutual linear correlation between caffeine and T-N or T-P (R 2  > 0.759) reflect the contribution of septic tank system effluents to the lower Asahikawa River Basin. Results of relative molecular indicators in combination with different molecular indicators (caffeine/carbamazepine and triclosan/carbamazepine) and cluster analysis better reflect the contribution of sewage than results obtained using concentrations of respective molecular indicators and cluster analysis. Relative molecular indicators used with water quality parameters (e.g., caffeine/T-N ratio) in this study provide results more clearly, relatively, and quantitatively than results obtained using molecular indicators alone. Moreover, the caffeine/T-N ratio reflects variations of caffeine flux from effluent sources. These results suggest strongly relative molecular indicators are also useful indicators, reflecting differences in spatial contributions of domestic sources for PPCPs in urban areas.

Sakata, S.; Kuribayashi, H.; Kono, Y.

1981-01-01

Both sea dumping and land isolation are planned to be accomplished for low level waste disposal in Japan. The conceptual design of land isolation facilities has been completed, and site selection will presently get underway. With respect to ocean dumping, safety surveys are being performed along the lines of the London Dumping Convention and the Revised Definitions and Recommendations of the IAEA, and the review of Japanese regulations and applicable criteria is being expedited. This paper discusses the present approach to waste solidification practices in Japan. It reports that the bitumen solidification process and the plastic solidification process are being increasingly used in Japan. Despite higher investment costs, both processes have advantages in operating cost, and are comparable to the cement solidification process in overall costs

Li, Angela; Robustelli, Briana L.; Whisman, Mark A.

2016-01-01

This study was conducted to examine the association between marital adjustment and psychological distress in a large, probability sample of married adults in Japan (N = 710) from the Midlife Development in Japan (MIDJA) study. Results indicate that positive and negative dimensions of marital adjustment were significantly associated with dimensional and categorical measures of psychological distress. Furthermore, the associations between marital adjustment and psychological distress remained significant when statistically controlling for neuroticism, quality of friend and family relationships, and demographic variables. These results demonstrate that the well-established association between marital adjustment and psychological distress found in European-American countries is also found in Japan. Findings support continued research on marital functioning and psychological distress in East Asian countries. PMID:28082761

This paper presents a brief report on the present status of future accelerator projects at the National Laboratory for High Energy Physics (KEK), Japan. The KEK laboratory has been successfully operating the TRISTAN accelerator complex since 1986. It consists of a 2.5 GeV electron/positron linac, an 8 GeV Accumulation Ring (AR) and a 29 GeV Main Ring (MR). Concurrently with this operation, in response to recommendations by the Japanese High Energy Physics Committee, survey studies have been continued on new accelerator facilities at KEK. They have two major future projects, namely, the asymmetric e + e - B-factory based on TRISTAN (TRISTAN-II) and the Japan Linear Collider (JLC). The purpose of this paper is to outline those research activities and to present an update on their status

Deterioration of aquatic ecosystems resulting from enhanced anthropogenic N loading has become an issue of increasing concern worldwide, and methods are needed to trace sources of N in rivers. Because nitrate from sewage is enriched in 15N relative to nitrate from natural soils, delta(15)N values of stream nitrate (delta(15)Nnitrate) should be an appropriate index of anthropogenic N loading to rivers, as should the delta(15)N values of riparian plants (delta(15)Nplant) because they are consumers of nitrate. We determined the delta(15)N values of stream nitrate and six species of riparian macrophytes in 31 rivers in the Lake Biwa Basin in Japan. We then tested the correlation between these values and various land-use parameters, including the percentage of land used for residential and agricultural purposes as well as for natural areas. These delta(15)N values were significantly positively correlated with land use (%) that had a high N load (i.e., residential or agricultural use) and significantly negatively correlated with forest (%). These findings indicate that delta(15)N values of stream nitrate and riparian plants might be good indicators of anthropogenic inputs of nitrogen.

Measuring energy poverty in Japan, 2004–2013

International Nuclear Information System (INIS)

Okushima, Shinichiro

2016-01-01

This paper first examines energy (or fuel) poverty in Japan from 2004 to 2013, especially around the time of the 2011 Great East Japan Earthquake (GEJE). To analyze the issue, the paper employs various poverty and vulnerability measures with the assistance of our unique dataset. The results indicate the aggravation of energy poverty among lower-income and vulnerable households during the past decade, resulting from both the escalation of energy prices and lowering of income. The analysis also employs a new decomposition technique and identifies the explanatory factors associated with the increase in energy poverty. These results suggest there were major changes in the forces driving the increase in energy poverty before and after the GEJE. After 2011, income alleviates energy poverty in Japan, with energy prices becoming the main driving factor. - Highlights: • This study is the first evaluation of energy poverty in Japan by unique microdata. • Focus on the period of the 2011 Great East Japan Earthquake and Fukushima accident. • Shows the aggravation of energy poverty among lower-income and vulnerable households. • Identifies factors accounting for the changes in energy poverty by decomposition. • Major changes in the explanatory factors before and after the Fukushima accident.

Climate Change Taxes and Energy Efficiency in Japan

International Nuclear Information System (INIS)

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

2007-01-01

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

The purpose of the project described in this report was to prepare an operative tool for making decisions about the operation of the power system on the river Otra (Norway) with regard to how this operation might affect the various users of the river system. Above all this affects fish, outdoor life and esthetic values. The connection between water quality and volume of discharge has been examined in a sub project. How suitable parts of the river are as habitats for trout has been simulated on a computer. From field investigation it is concluded that near the Steinfoss power station the physical conditions for trout depend on the operation of the river system.

[Establishment of anatomical terminology in Japan].

Shimada, Kazuyuki

2008-12-01

The history of anatomical terminology in Japan began with the publication of Waran Naikei Ihan-teimŏ in 1805 and Chŏtei Kaitai Shinsho in 1826. Although the establishment of Japanese anatomical terminology became necessary during the Meiji era when many western anatomy books imported into Janan were translated, such terminology was not unified during this period and varied among translators. In 1871, Tsukumo Ono's Kaibŏgaku Gosen was published by the Ministry of Education. Although this book is considered to be the first anatomical glossary terms in Japan, its contents were incomplete. Overseas, the German Anatomical Society established a unified anatomical terminology in 1895 called the Basle Nomina Anatomica (B.N.A.). Based on this development, Kaibŏgaku Meishŭ which follows the BNA, by Buntarŏ Suzuki was published in 1905. With the subsequent establishment in 1935 of Jena Nomina Anatomica (J.N.A.), the unification of anatomical terminology was also accelerated in Japan, leading to the further development of terminology.

Insights into software development in Japan

Duvall, Lorraine M.

1992-01-01

The interdependence of the U.S.-Japanese economies makes it imperative that we in the United States understand how business and technology developments take place in Japan. We can gain insight into these developments in software engineering by studying the context in which Japanese software is developed, the practices that are used, the problems encountered, the setting surrounding these problems, and the resolution of these problems. Context includes the technological and sociological characteristics of the software development environment, the software processes applied, personnel involved in the development process, and the corporate and social culture surrounding the development. Presented in this paper is a summary of results of a study that addresses these issues. Data for this study was collected during a three month visit to Japan where the author interviewed 20 software managers representing nine companies involved in developing software in Japan. These data are compared to similar data from the United States in which 12 managers from five companies were interviewed.

Japan's spent fuel and plutonium management challenge

International Nuclear Information System (INIS)

Katsuta, Tadahiro; Suzuki, Tatsujiro

2011-01-01

Japan's commitment to plutonium recycling has been explicitly stated in its long-term program since 1956. Despite the clear cost disadvantage compared with direct disposal or storage of spent fuel, the Rokkasho reprocessing plant started active testing in 2006. Japan's cumulative consumption of plutonium has been only 5 tons to date and its future consumption rate is still uncertain. But once the Rokkasho reprocessing plant starts its full operation, Japan will separate about 8 tons of plutonium annually. Our analysis shows that, with optimum use of available at-reactor and away-from-reactor storage capacity, there would be no need for reprocessing until the mid-2020s. With an additional 30,000 tons of away-from-reactor (AFR) spent-fuel storage capacity reprocessing could be avoided until 2050. Deferring operation of the Rokkasho plant, at least until the plutonium stockpile had been worked down to the minimum required level, would also minimize international concern about Japan's plutonium stockpile. The authors are happy to acknowledge Frank von Hippel, Harold Feiveson, Jungming Kang, Zia Mian, M.V. Ramana, and other IPFM members, as well as the generous grant from the MacArthur Foundation for helping make this research possible.

Long-term immunosuppression is associated with an increased risk of cancer. Especially, the immunosuppression in pancreas transplantation is more intensive than that in other organ transplantation because of its strong immunogenicity. Therefore, it suggests that the risk of post-transplant de novo malignancy might increase in pancreas transplantation. However, there have been few studies of de novo malignancy after pancreas transplantation. The aim of this study was to analyze the incidence of de novo malignancy after pancreas transplantation in Japan. Post-transplant patients with de novo malignancy were surveyed and characterized in Japan. Among 107 cases receiving pancreas transplantation in Japan between 2001 and 2010, de novo malignancy developed in 9 cases (8.4%): post-transplant lymphoproliferative disorders in 6 cases, colon cancer in 1 case, renal cancer in 1 case, and brain tumor in 1 case. We clarified the incidence of de novo malignancy after pancreas transplantation in Japan. Copyright © 2015 Elsevier Inc. All rights reserved.

Japan's search for identity in the nuclear age

Energy Technology Data Exchange (ETDEWEB)

Kenzaburo, O.

Japan's position has been one of an outsider in the nuclear age at the same time it has been a victim to the first use of atomic weapons. Quoting from Japanese poets and writers, the author constructs a model of the time to create an image of modern Japan's cultural identity as a result of the Meiji Restoration and the close of World War II. The end of the Emperor System and alienation from the rest of Asia are significant consequences of these events. The author feels that current arguments that Japan should arm itself with nuclear weapons ignore the miseries Japan alone has felt and should be restricted. Although a new Japanism which is oriented away from western culture is emerging today, efforts to rediscover the folk culture can also recapture the nonnuclear vision of 1945. (DCK)

First-flush loads of perfluorinated compounds in stormwater runoff from Hayabuchi River basin, Japan served by separated sewerage system.

Science.gov (United States)

Zushi, Yasuyuki; Masunaga, Shigeki

2009-08-01

Worldwide environmental pollution by perfluorinated compounds (PFCs) has been reported. PFCs have also been reported to have nonpoint sources (NPSs). A fixed-point hourly monitoring in the river was conducted during a storm event using an automatic sampler to estimate the impact of the first-flush of PFCs from NPS in this study. Perfluorocarboxylates (PFCAs) and perfluoroalkyl sulfonates (PFASs) with different chain lengths were monitored. The concentrations of short- to medium-chain-length PFCAs such as PFHpA, PFOA and PFNA, and PFASs such as PFBS, PFPeS, PFHxS, PFHpS and PFOS showed no marked increase with the storm-runoff event. However, in contrast to this, concentrations of long-chain-length PFCAs such as PFDA and PFUnA increased markedly. The concentrations of PFDA and PFUnA increased 3.4 (1.5-5.0 ng L(-1))- and 2.0 (3.3-6.7 ng L(-1))-fold, respectively. This study demonstrates that large loads of long-chain-length PFCAs are discharged to the Hayabuchi River during the first-flush after the rain event.

Japan and Austria are among the OECD countries with an average labour force participation rate but an above average gender gap as far as employment opportunities and earnings are concerned. In Japan, women in the main working age have a fairly large margin of labour resources not employed in the market economy. In Austria in contrast, the proportion of unused labour resources of mature workers is high, and the gender gap is less pronounced than in Japan, which suggests that a different combin...

A QUARTER CENTURY OF NUCLEAR WASTE MANAGEMENT IN JAPAN

Tracing anthropogenic inputs to production in the Seto Inland Sea, Japan - A stable isotope approach

International Nuclear Information System (INIS)

Miller, Todd W.; Omori, Koji; Hamaoka, Hideki; Shibata, Jun-ya; Hidejiro, Onishi

2010-01-01

The Seto Inland Sea (SIS) receives waste runoff from ∼24% of Japan's total population, yet it is also important in regional fisheries, recreation and commerce. During August 2006 we measured carbon and nitrogen stable isotopes of particulate organic matter (POM) and zooplankton across urban population gradients of the SIS. Results showed a consistent trend of increasing δ 15 N in POM and zooplankton from the western to eastern subsystems of the SIS, corresponding to increasing population load. Principal components analysis of environmental variables indicated high positive loadings of δ 15 N and δ 13 C with high chlorophyll-a and surface water temperatures, and negative loadings of low salinities related to inputs from large rivers and high urban development in the eastern SIS. Anthropogenic nitrogen was therefore readily integrated into the SIS food web from primary production to copepods, which are a critical food source for many commercially important fishes.

Hasegawa, Hidenao; Ueda, Shinji; Kakiuchi, Hideki; Hisamatsu, Shun'ichi; Akata, Naofumi

2015-01-01

Tritium ( 3 H) concentrations were measured in groundwater samples from four surface wells (4-10 m deep), four shallow wells (24-26.5 m deep) and a 150-m-deep well in the Futamata River catchment area, which is adjacent to the large-scale commercial spent nuclear fuel reprocessing plant in Rokkasho, Japan. The 3 H concentrations in most of the surface- and shallow-well samples (<0.03-0.57 Bq l -1 ) were similar to those in precipitation (annual mean: 0.31-0.79 Bq l -1 ), suggesting that the residence time of the water in those wells was 0-15 y. The 3 H concentrations in the samples from a 26-m-deep well and the 150-m-deep well were lower than those in the other wells, indicating that groundwater with a long residence time exists in deep aquifers and the estuary area of the catchment. It is not clear whether 3 H released during test operation of the plant with actual spent nuclear fuel affected the 3 H concentrations observed in this study. (authors)

Thyroid storm is an endocrine emergency which is characterized by multiple organ failure due to severe thyrotoxicosis, often associated with triggering illnesses. Early suspicion, prompt diagnosis and intensive treatment will improve survival in thyroid storm patients. Because of its rarity and high mortality, prospective intervention studies for the treatment of thyroid storm are difficult to carry out. We, the Japan Thyroid Association and Japan Endocrine Society taskforce committee, previously developed new diagnostic criteria and conducted nationwide surveys for thyroid storm in Japan. Detailed analyses of clinical data from 356 patients revealed that the mortality in Japan was still high (∼11%) and that multiple organ failure and acute heart failure were common causes of death. In addition, multimodal treatment with antithyroid drugs, inorganic iodide, corticosteroids and beta-adrenergic antagonists has been suggested to improve mortality of these patients. Based on the evidence obtained by nationwide surveys and additional literature searches, we herein established clinical guidelines for the management of thyroid storm. The present guideline includes 15 recommendations for the treatment of thyrotoxicosis and organ failure in the central nervous system, cardiovascular system, and hepato-gastrointestinal tract, admission criteria for the intensive care unit, and prognostic evaluation. We also proposed preventive approaches to thyroid storm, roles of definitive therapy, and future prospective trial plans for the treatment of thyroid storm. We hope that this guideline will be useful for many physicians all over the world as well as in Japan in the management of thyroid storm and the improvement of its outcome.

HIV/AIDS and professional freedom of expression in Japan.

A senior physician with a government role in Japan made a widely reported and misleading statement about Thailand's policy on HIV/AIDS patients. He claimed that in Thailand the policy is to spend public money on the prevention of HIV infection while allowing AIDS patients to die untreated. The author, a community nursing specialist in Japan with first-hand knowledge of HIV/AIDS policy in Thailand, thought that this statement would influence attitudes negatively in Japan. However, speaking out about this misrepresentation of the facts carried certain risks. Although freedom of expression is valued in Japan, in practice it is not easy to contradict senior medical professionals. The author uses his experience of this difficult professional situation to teach nurses how to approach speaking out in the public interest.

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

Solid state ionics: a Japan perspective

Yamamoto, Osamu

2017-12-01

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

Full Text Available Traditional Japanese dietary culture might be a factor contributing to the high life expectancy in Japan. As little is known about what constitutes traditional and modern eating in Japan, the aims of the current study were to (1 comprehensively compile and systematize the various facets of traditional and modern eating; and (2 investigate whether these facets also apply to traditional and modern eating in Japan. In Study 1, an extensive international literature review was performed. Forty-five facets of traditional and modern eating were compiled and systematized into the dimensions of what and how people eat, and into eleven separate subdimensions. In Study 2, 340 adults from Japan answered a questionnaire. Results showed that traditional and modern eating in Japan is reflected in both what and how people eat. Within these two dimensions, ten subdimensions were found: the ingredients, processing, temporal origin, spatial origin, and variety of consumed foods, as well as temporal, spatial, and social aspects, appreciation, and concerns when eating. This study provides a broad compilation of facets of traditional and modern eating in Japan. Future research should investigate how these facets are related to life expectancy and health.

How sustainable is Japan's foreign aid policy? An analysis of Japan's official development assistance and funding for energy sector projects

Science.gov (United States)

Yamaguchi, Hideka

Japan has adopted a sustainable development strategy since the late 1980s in the effort to address social and environmental damages caused by past Japan-funded projects in partner nations. Even after about a decade and a half of the policy implementation, however, there are few reports which critically examine effects of the adoption of the idea of sustainable development. This dissertation evaluates Japan's foreign aid policy to determine the extent to which new revisions of aid policy have improved the environmental sustainability of the policy. This dissertation reviews the mainstream idea of sustainable development (also known as the sustainable development paradigm in this dissertation) to reveal the nature of the idea of sustainable development that Japan's foreign aid policy depends on. A literature review of two development discourses---modernization theory and ecological modernization theory---and three types of critiques against the sustainable development paradigm---focused on adverse impacts of modern science, globalization, and environmental overuse---reveals core logics of and problems with the sustainable development paradigm. Japan's foreign aid policy impacts on energy sector development in recipient countries is examined by means of a quantitative analysis and a qualitative analysis. Specifically, it examines the effect of Japan's ODA program over fifteen years that proposed to facilitate sustainable development in developing countries. Special emphasis is given to investigation of ODA disbursements in the energy sector and detailed case studies of several individual energy projects are performed. The dissertation discovers that the sustainable development paradigm guiding Japan's ODA has little capacity to accomplish its goals to bring about social and ecological improvement in developing countries. This dissertation finds three fundamental weaknesses in Japanese ODA policy on energy sector development as well as the sustainable development

This study measured the microbial processes of anaerobic ammonium oxidation (anammox) and denitrification in sediment sampled from two sites in the estuary of an inland river (Koisegawa River, Ibaragi prefecture, Japan) using a nitrogen isotope pairing technique (IPT). The responses of anammox and denitrification activities to temperature and nitrate concentration were also evaluated. Further, to elucidate the correlation between anammox and denitrification processes, an inhibition experiment was conducted, using chlorate to inhibit the first step of denitrification. Denitrification activity was much higher than anammox activity, and it reached a maximum at the surface layer in February 2012. Denitrification activity decreased as sediment depth increased, and a similar phenomenon was observed for anammox activity in the sediment of site A, where aquatic plants were absent from the surroundings. The activities of both denitrification and anammox were temperature-dependent, but they responded differently to changes in incubation temperature. Compared to a linear increase in denitrification as temperature rose to 35 °C, the optimal temperature for anammox was 25 °C, after which the activity decreased sharply. At the same time, both anammox and denitrification activities increased with NO{sub 3}{sup −} concentration. The Michaelis–Menten kinetic constants (V{sub max} and K{sub m}) of denitrification were significantly higher than those of the anammox process. Furthermore, anammox activity decreased accordingly when the first step of denitrification was inhibited, which probably reduced the amount of the intermediate NO{sub 2}{sup −}. Our study provides the first direct exploration of the denitrification-dependent correlation of anammox activity in the sediment of inland river. - Highlights: • The activity of denitrification in river sediment was much higher than anammox. • Denitrification and anammox respond differently to changes in temperature. �

2013-01-01

The Fukushima Daiichi NPP accident deeply questioned the bases of nuclear safety and nuclear safety regulation in Japan. It also resulted in a considerable loss of public confidence in the safety of nuclear power across the world. Although the accident was caused by natural phenomena, institutional and human factors also largely contributed to its devastating consequences, as shown by the Japanese Diet's and Government's investigation reports. 'Both regulators and licensees were held responsible and decided to fully reconsider the existing approaches to nuclear safety. Consequently, the regulatory system underwent extensive reform based on the lessons learned from the accident,' Yoshihiro Nakagome, the President of Japan Nuclear Energy Safety Organisation, an ETSON member TSO, explains.

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

Fast Reactor development experiences and status in Japan are summarized. Even though international SFR circumstances were against in 1980s and 1990s, e.g. CRBRP, SNR-300 and Superphenix terminations, we kept on with our R and D activities steadily aiming at positive development targets in Japan. As results of our efforts, it has shown that our commercialized SFR concept, Japan Sodium-cooled Fast Reactor (JSFR) could meet the targets in the Feasibility Study on Commercialized Fast Reactor Cycle Systems (FS) and the Fast Reactor Cycle Technology Development (FaCT) project. Further, Monju has finally achieved restart in May 2010 after having been shut for almost 15 years. A future plan of Monju is to be determined based on a direction of the national nuclear and energy policies that will be established in 2012. The undergoing FaCT project is pursuing commercialization of fast reactor cycle system around 2050 under cooperation of MEXT (Ministry of Education, Culture, Sports, Science and Technology), METI (Ministry of Economy, Trade and Industry), utilities, venders and JAEA (Japan Atomic Energy Agency). As results of the FaCT Phase I, feasibility of the key technologies for JSFR has been evaluated and the project is waiting for launching the phase II due to the Tohoku large earthquake. It is considered that the nuclear development policy might be affected by the Tohoku large Earthquake/Tsunami in Japan. Nevertheless the significance of nuclear energy will not be changed and thus we will focus on the issues learnt from Fukushima accidents and reflect into the improvement of the safety of Monju and the safety design criteria for the next generation Fast Reactor systems.

Niina, Toshiaki; Matsunaga, Takeshi; Amano, Hikaru

1996-02-01

As a basic research with a aim to clarify the migration behavior of radionuclides in rivers, the characteristics of dissolved ions and organic substances in river water, which characteristics may affect the behavior, was investigated. The investigation was carried out for the Kuji river in the northern Kanto district (Japan) comprising four sampling campaigns in 1994 for 10 locations from the upstream to the downstream. Concentrations of major ions, iron and manganese species and organic substances were analyzed in laboratory. Values of temperature of the water, pH, conductivity, dissolved oxygen were measured in the field. This investigation was conducted mainly under low water flow conditions of the river, while a limited number of campaigns were under high flow conditions due to precipitation events. The concentrations of major inorganic ions increased steadily toward the down-stream, resulting in approximately two times increase for the traveling distance of 100 km. They showed a seasonal variation that they were highest in the spring and lowest in the autumn when there were most concentrated precipitation events in a year. The constituents were mainly Na + , Ca 2+ , SO 4 2- and HCO 3 - , and were similar for every sampling locations and seasons. Concentrations of dissolved organic substances (carbon compounds) were lowest in the upstream and increased about twice in the downstream as well as major inorganic ions. Their level was 1-3 mg/l, which can be ranked as relatively lower in general values for fresh water environments. They were highest in the spring (average over the locations: 2.2 mg/l) and lowest in the autumn (1.3 mg/l) and also in the winter (1.3 mg/l). These results will be useful as a basic understanding of spatial and seasonal variations of river water chemistry, especially related to the organic substances which can bind with radionuclides to make a mobile complex.

Overall 20 surface water samples were collected from the Yangtze River, the Wangyu River and the Gonghu Bay (Lake Taihu) to clarify the pollution characteristics of nitrogen and phosphorus during 2 sample stages of "Water Transfers on Lake Taihu from the Yangtze River" in August and December of 2013 respectively. The results showed that the mass concentrations of NO2- -N, NO3- -N, NH4+ -N and TN in the Gonghu Bay were lower than those of the Yangtze River and Wangyu River during the 2 water transfer processes. However, there was higher level of DON content in the Gonghu Bay than that of the Yangtze River and Wangyu River. The percentages of various N species showed that NO3- -N was the major N species in the Yangtze River and Wangyu River during the 2 water transfer processes. TP contents in samples collected from the Yangtze River displayed a constant trend compared with the Wangyu River. However, the percentages of various P species were different with each other during the 2 water transfer processes. Mass concentrations of DON and TP in surface water in August were higher than those in December and the contents of NO3- -N and TDP were lower in August than those in December. In general, NO3- -N and TPP were the main N and P species in Wangyu River from the Yangtze River. NO3- -N, PO4(3-) -P and TPP were the main N and P species in Gonghu Bay from Wangyu River during the 2 water transfer processes.

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

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

2012-12-01

The Department of Civil and Environmental Engineering, Outdoor Recreation, and Parks and Recreation programs at Utah State University (USU) have partnered to offer a new, unique river-based experiential learning opportunity for undergraduates called the Bear River Fellows Program. The program allows incoming freshmen Fellows to experience a river first hand during a 5-day/4-night river trip on the nearby Bear River two weeks before the start of their first Fall semester. As part of the program, Fellows will navigate the Bear River in canoes, camp along the banks, interact with local water and environmental managers, collect channel cross section, stream flow, vegetation cover, and topological complexity data, meet other incoming freshmen, interact with faculty and graduate students, develop boating and leadership skills, problem solve, and participate as full members of the trip team. Subsequently, Fellows will get paid as undergraduate researchers during their Fall and Spring Freshman semesters to analyze, synthesize, and present the field data they collect. The program is a collaborative effort between two USU academic units and the (non-academic) division of Student Services and supports a larger National Science Foundation funded environmental modelling and management project for the lower Bear River, Utah watershed. We have advertised the program via Facebook and emails to incoming USU freshmen, received 35 applications (60% women), and accepted 5 Fellows into the program (3 female and 2 male). The river trip departs August 14, 2012. The poster will overview the Bear River Fellows Program and present qualitative and preliminary outcomes emerging from the trip and Fellows' work through the Fall semester with the field data they collect. We will also undertake more rigorous and longer longitudinal quantitative evaluation of Program outcomes (for example, in problem-solving and leadership) both in Spring 2013 and in subsequent 2013 and 2014 offerings of the

There are two types of repositories for the low level radioactive wastes in Japan. One is a trench type repository only for concrete debris generated from the dismantling of the research reactor. According to the safety assurance system, Japan Atomic Energy Research Institute (JAERI) has disposed of the concrete debris arose from the dismantling of the Japan Power Demonstration Reactor (JPDR). The other type is the concreted pit with engineered barriers. Rokkasho Low Level Radioactive Waste Disposal Center has this type of repository mainly for the power plant wastes. Japan Nuclear Fuel Ltd. (JNFL) established by electric power companies is the operator of the LLW disposal project. JNFL began the storage operation in 1992 and buried approximately 60,000 drums there. Two hundred thousand drums of uniformly solidified, waste may be buried ultimately. 4 refs, 3 tabs

The parasite is traditionally found in developing countries where undercooked pork is consumed under poor sanitary conditions and/or as part of traditional food cultures. However, the recent increase in international tourism and immigration is spreading the disease into non-endemic developed countries such as the United States. Although there has been concern that the number of cysticercosis cases is increasing in Japan, the current situation is not clear. This is largely because taeniasis and cysticercosis are not notifiable conditions in Japan and because there have been no comprehensive reviews of T. solium infections in Japan conducted in the last 15 years. Herein, we provide an overview of the status of T. solium infection in Japan over the past 35 years and point out the potential risks to Japanese society.

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

In the Wake of TICAD V: Japan-Africa Relations Today

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?

Nuclear fuel cycle in Japan : status and perspective

International Nuclear Information System (INIS)

Suzuki, Atsuyuki

1996-01-01

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

Because Japan is a primary investor and trading partner of all the troubled economies, in the midst of the crisis, Japan was called in to help the crisis-stricken countries by opening its market to cheaper imports from South East Asia. The article analyses the opening to trade of the Japanese economy with the help of a gravity equation on panel data using a Hausman-Taylor estimator. We show that there is no certainty that such a role, that is the opening of Japan, will have positive effects f...

Public acceptance (PA) of nuclear energy in Japan

Ishii, Makoto

1994-01-01

Japan's nuclear development is carried out in the spirit of the Atomic Energy Basic Law that it adopted in 1955. The only nation in the world devastated by nuclear weapons, Japan strongly hopes for the abolishment of nuclear weapons and promotes the peaceful use of nuclear energy. Since Japan is in poor in natural resources nuclear power has now become a major foundation of our society and economy. As far as the Japanese people's awareness of nuclear power generation is concerned, 60% recognize it as necessary although 70% are concerned about its safety. The public acceptance (PA) of nuclear energy is facing a critical juncture at thus point due to such imminent issues as the use of plutonium and the disposal of high-level wastes. The entire Japanese government is currently striving to promote PA measures targeting various population groups. This paper reports on the peaceful use of nuclear energy and Japan's stance on this issue; people's awareness; and the current state of nuclear energy PA measures. 1 fig

RiverCare: towards self-sustaining multifunctional rivers

Rivers are inherently dynamic water systems involving complex interactions among hydrodynamics, morphology and ecology. In many deltas around the world lowland rivers are intensively managed to meet objectives like safety, navigation, hydropower and water supply. With the increasing pressure of growing population and climate change it will become even more challenging to reach or maintain these objectives and probably also more demanding from a management point of view. In the meantime there is a growing awareness that rivers are natural systems and that, rather than further regulation works, the dynamic natural processes should be better utilized (or restored) to reach the multifunctional objectives. Currently many integrated river management projects are initiated all over the world, in large rivers as well as streams. Examples of large scale projects in the Netherlands are 'Room for the River' (Rhine), the 'Maaswerken' (Meuse), the Deltaprogramme and projects originating from the European Water Framework Directive (WFD). These projects include innovative measures executed never before on this scale and include for example longitudinal training dams, side channels, removal of bank protection, remeandering of streams, dredging/nourishment and floodplain rehabilitation. Although estimates have been made on the effects of these measures for many of the individual projects, the overall effects on the various management objectives remains uncertain, especially if all projects are considered in connection. For all stakeholders with vested interests in the river system it is important to know how that system evolves at intermediate and longer time scales (10 to 100 years) and what the consequences will be for the various river functions. If the total, integrated response of the system can be predicted, the system may be managed in a more effective way, making optimum use of natural processes. In this way, maintenance costs may be reduced, the system remains more natural

Mobility perspective for a local city in Japan

Another solution to excessive automobile dependency is bicycles, which are a convenient and inexpensive transportation mode all over the world. In Japan, however, automobile-oriented transportation and urban policies have prevailed, leaving the bicycle long neglected. Still, recent years have seen the bicycle gain recognition as a healthy, environmentally friendly alternative to the automobile, especially after the Great East Japan Earthquake in 2011. Utsunomiya City has been actively pursuing a mobility policy of bicycle utilization since 2003 and is regarded as one of the leaders in its promotion. The potential success in Utsunomiya to overcome automobile dependency will make it a model for many local cities in Japan that suffer from similar problems.

In the safety assessment for a geological disposal of long-lived radioactive waste such as high-level radioactive waste and TRU waste etc, it is important to estimate radionuclide migration to human environment through groundwater flow system. Japan Atomic Energy Agency (JAEA) has investigated a sedimentary rock area in the Yoro river basin, in Chiba Prefecture. The hydrological and geo-chemical approach is necessary for revealing the conditions of the groundwater flow system. For the purpose of establishing a methodology for these approach, investigations of flow rates and chemical compositions, isotopic ratios of hydrogen and oxygen for water samples collected from wells, rivers and springs were carried out in the 3 feeder streams as Urajiro, Imohara and Umegase river locating at the central part of the Yoro river basin. As a result, flow rates and chemical composition data suggested that considerable amount of ground water cultivated at the high permeable sand dominant layer (Daifuku Mt.) preferentially flows toward its strike direction discharging at the downstream region of Imohara and the Umegase river. The rest of the ground water was inferred to form different flowpath toward the dipping direction of bedrock more than 100m at depth and to upwell to the Urajiro River through the low permeable mud layer. Chemical composition and isotopic data indicated that most of the ground water in meteoric water origin is NaCa-HCO 3 type as represented by surface water or the evolved Ca-HCO 3 type water but the part of the upwelling water at the downstream region of Urajiro river is Na-HCO 3 type water with long residence time. This study shows that both hydrological and geo-chemical approach could be available to evaluate the relationships between shallow water and deep-seated groundwater, so it is necessary to apply this approach to regional ground water flow systems.

In Japan, rotavirus hospitalisation occurs at a rate from 2.8 to 13.7 per 1000 child-years among children age less than 5 years, and it imposes a substantial burden to the healthcare system in the country. While both monovalent (RV1) and pentavalent (RV5) rotavirus vaccines are licensed in Japan, neither has been incorporated in the national infant immunization programme. In this study, we estimated vaccine effectiveness (VE) in Japan. This study was conducted in Yuri-Kumiai General Hospital located in a city in the north-western part of Japan. Age-eligible children for rotavirus vaccination were enrolled if they were hospitalized for rotavirus gastroenteritis between September 2013 and August 2016. Rotavirus gastroenteritis was defined by the detection of rotavirus antigen by immunochromatography. "Vaccinated" was defined as infant inoculated with at least one dose of either RV1 or RV5. A conditional logistic regression analysis was performed by modelling the year of birth, year of admission, residence of the children and vaccination status, and by matching the age of cases with that of test-negative controls. The adjusted odds ratio of the vaccinated over unvaccinated was then used to calculate VE in the formula of (1 - adjusted odds ratio) × 100. Out of the 244 patients enrolled, rotavirus antigen was detected in 55 (22.5%) of whom 10 (18.2%) were vaccinated, whereas 94 (49.7%) of 189 test-negative controls were vaccinated. During the study period, the vaccine uptake rate in the controls increased from 36.2% to 61.8%. On the other hand, the vaccination coverage over the three years was 64.2% in Yuri-Honjo city (three quarters of the catchment), and 91.4% in Nikaho city (one quarter of the catchment). The VE was calculated to be 70.4% (95% confidence interval: 36.0-86.4%, P = 0.002). The point estimate of the VE was lower but its 95% confidence interval overlaps those of the efficacies obtained from clinical trials in Japan. The rotavirus vaccine was

Concentrations of stable elements and uranium in estuarine areas of Japan

The geochemistry of stable elements can be a good analogue for understanding the behavior of radionuclides in estuarine and coastal environments. In this study, the behavior of nutrients (NO 3 + NO 2 , PO 4 , Si(OH) 4 ), heavy metals, and U was observed in several estuarine and coastal waters of Japan. We also collected data on salinity, pH, and suspended particle matter (SPM). Nutrient concentrations followed conservative dilution lines in these estuaries, and concentrations of dissolved Fe decreased as salinity increased from 0 to 20. In general, most of the dissolved Fe in estuaries is in colloidal form. The behavior of dissolved Fe might reflect a loss of colloidal Fe through coagulation in this salinity range. Dissolved Co and Ni concentrations followed approximate dilution lines from the rivers to the seawater end-members, suggesting that they were quasi-conservative in these estuarine systems. A rapid increase in dissolved Cd concentrations was observed at low levels of salinity (<4). Estimated fluxes of dissolved Cd to the estuarine and coastal waters showed that the salt-induced desorption of Cd from particles constitutes a significant source of dissolved Cd in the estuarine and coastal waters.

In February 2017, the Grand River Dam Authority filed to relicense the Pensacola Hydroelectric Project with the Federal Energy Regulatory Commission. The predominant feature of the Pensacola Hydroelectric Project is Pensacola Dam, which impounds Grand Lake O’ the Cherokees (locally called Grand Lake) in northeastern Oklahoma. Identification of information gaps and assessment of project effects on stakeholders are central aspects of the Federal Energy Regulatory Commission relicensing process. Some upstream stakeholders have expressed concerns about the dynamics of sedimentation and flood flows in the transition zone between major rivers and Grand Lake O’ the Cherokees. To relicense the Pensacola Hydroelectric Project with the Federal Energy Regulatory Commission, the hydraulic models for these rivers require high-resolution bathymetric data along the river channels. In support of the Federal Energy Regulatory Commission relicensing process, the U.S. Geological Survey, in cooperation with the Grand River Dam Authority, performed bathymetric surveys of (1) the Neosho River from the Oklahoma border to the U.S. Highway 60 bridge at Twin Bridges State Park, (2) the Spring River from the Oklahoma border to the U.S. Highway 60 bridge at Twin Bridges State Park, and (3) the Elk River from Noel, Missouri, to the Oklahoma State Highway 10 bridge near Grove, Oklahoma. The Neosho River and Spring River bathymetric surveys were performed from October 26 to December 14, 2016; the Elk River bathymetric survey was performed from February 27 to March 21, 2017. Only areas inundated during those periods were surveyed.The bathymetric surveys covered a total distance of about 76 river miles and a total area of about 5 square miles. Greater than 1.4 million bathymetric-survey data points were used in the computation and interpolation of bathymetric-survey digital elevation models and derived contours at 1-foot (ft) intervals. The minimum bathymetric-survey elevation of the Neosho

Since June 1997 the standards/specifications and inspection/certification of various products in Japan have been reviewed by Ministries and Agencies, with the aim of reducing direct government intervention to a necessary minimum and creating a free and fair socio-economic system that is fully opened to the international community and based on the rules of self-responsibility and market principles. Reflecting this policy the administrative regulations which prescribe technical standards as specific requirements have been revised by degrees into performance prescriptions. Detailed provisions in ordinances and notices have been abolished gradually to utilize voluntary standards and rules. In the nuclear energy field voluntary standards are being developed to make up statutory performance requirements by the Atomic Energy Society of Japan (AESJ) and the Japan Society of Mechanical Engineers (JSME) together with other organizations such as the Japan Electric Association, the Thermal and Nuclear Power Engineering Society. These voluntary standards and rules by these organizations have been established in order to maintain openness, transparency, fairness, professionalism and promptness and to promote development and globalization

The graying of Japan.

Japan's rapidly aging population has become a top policy issue, especially as the increasing costs of pensions and medical care are debated. With the highest life expectancy on earth, the Japanese potentially face long periods of retirement, as well as the possibility of long periods of disability. Although family support of the elderly is thought to have been strong traditionally, the recent decline in co-residence with children is 1 indication that the way support is given may be changing. This issue is of particular concern to the government, which wants to avoid any greater responsibility for the elderly than is necessary given the dramatic population aging yet to come. The government is also encouraging employers to provide more employment opportunities for the elderly at the same time that it is trying to raise the eligibility age for the receipt of public pensions. There is resistance on the part of employers, however, because wages and retirement allowances in Japan are positively related to length of employment. Furthermore, it is not clear whether elderly Japanese of the future will be as willing to work, if they learn to enjoy increased leisure early in their careers. Nevertheless, it is unlikely that population aging will lead to Japan's economic decline. Although the savings rate may decline somewhat, restructuring of the economy and continued overseas investment should keep the economy growing in the long run. Important in both the care of the frail elderly and the continued growth of the economy will be the roles played by middle-aged Japanese women.

River classification is very important to know the river characteristic in study areas, where this database can help to understand the behaviour of the river. This article discusses about river classification using Chemometrics techniques in mainstream of Pahang River. Based on river survey, GIS and Remote Sensing database, the chemometric analysis techniques have been used to identify the cluster on the Pahang River using Hierarchical Agglomerative Cluster Analysis (HACA). Calibration and validation process using Discriminant Analysis (DA) has been used to confirm the HACA result. Principal Component Analysis (PCA) study to see the strong coefficient where the Pahang River has been classed. The results indicated the main of Pahang River has been classed to three main clusters as upstream, middle stream and downstream. Base on DA analysis, the calibration and validation model shows 100 % convinced. While the PCA indicates there are three variables that have a significant correlation, domination slope with R"2 0.796, L/D ratio with R"2 -0868 and sinuosity with R"2 0.557. Map of the river classification with moving class also was produced. Where the green colour considered in valley erosion zone, yellow in a low terrace of land near the channels and red colour class in flood plain and valley deposition zone. From this result, the basic information can be produced to understand the characteristics of the main Pahang River. This result is important to local authorities to make decisions according to the cluster or guidelines for future study in Pahang River, Malaysia specifically and for Tropical River generally. The research findings are important to local authorities by providing basic data as a guidelines to the integrated river management at Pahang River, and Tropical River in general. (author)

This study computes the regional total-factor energy efficiency (TFEE) in Japan by employing the data envelopment analysis (DEA). A dataset of 47 prefectures in Japan for the period 1993-2003 is constructed. There are 14 inputs, including three production factors (labor employment, private, and public capital stocks) and 11 energy sources (electric power for commercial and industrial use, electric power for residential use, gasoline, kerosene, heavy oil, light oil, city gas, butane gas, propane gas, coal, and coke). GDP is the sole output. Following Fukao and Yue [2000. Regional factor inputs and convergence in Japan - how much can we apply closed economy neoclassical growth models? Economic Review 51, 136-151 (in Japanese)], data on private and public capital stocks are extended. All the nominal variables are transformed into real variables, taking into consideration the 1995 price level. For kerosene, gas oil, heavy oil, butane gas, coal, and coke, there are a few prefectures with TFEEs less than 0.7. The five most inefficient prefectures are Niigata, Wakayama, Hyogo, Chiba, and Yamaguchi. Inland regions and most regions along the Sea of Japan are efficient in energy use. Most of the inefficient prefectures that are developing mainly upon energy-intensive industries are located along the Pacific Belt Zone. A U-shaped relation similar to the environmental Kuznets curve (EKC) is discovered between energy efficiency and per capita income for the regions in Japan. (author)

Confusion surrounding the concept of nuclear 'security'. 'Preventing Japan from going nuclear contributes to Japan's national security'?

International Nuclear Information System (INIS)

Kubota, Masafumi

2012-01-01

A law enacted on June 20 to establish a new Nuclear Regulatory Authority (NRA) fully separated from the nuclear promotional authorities. It added the provision, which says nuclear safety should be guaranteed not only to defend lives, people's health and the environment but also to 'contribute to Japan's national security', to Article 2 of the Atomic Energy Basic Law. NRA integrated the existing regulatory authorities for safety, security and safeguards, into one. Supporters of an amendment quietly slipped into the law were denying it could provide cover for military use of nuclear technology, but arouse international concern about recycling program of extracting plutonium from spent fuels. Nuclear policy minister said: 'The safeguards are in place to prevent nuclear proliferation. The world 'security' precisely means the prevention of nuclear proliferation.' If not used explicitly about safeguards, they left room for stretched interpretation. The author recommended the world' contribute to Japan's national security' should be deleted instead of explaining appropriately, both at home and abroad, the use of nuclear power in Japan limited to peaceful purposes.

Transcatheter aortic valve replacement (TAVR) has been an alternative less invasive therapy for high-surgical risk/inoperable patients with aortic valve stenosis (AS) in Japan. We report 5-year outcomes of the first pivotal clinical trial of TAVR in Japan (PREVAIL JAPAN).Methods and Results:A total of 64 patients with AS who were considered unsuitable candidates for surgery were enrolled at 3 centers in Japan (mean age: 84.3±6.1 years, female: 65.6%, STS score: 9.0±4.5%). Transfemoral approach (TF) and transapical approach (TA) was performed in 37 patients and 27 patients, respectively. At 5 years, freedom from all-cause death was 52.7% (TF: 51.3%, TA: 56.3%). Risk of all stroke at 5-year was 15.8% (TF: 8.9%, TA: 25.5%) and risk of major adverse cardiac and cerebrovascular events at 5 years was 58.0% (TF: 51.3%, TA: 69.2%). Mild or greater aortic regurgitation (AR) at 1 week was not associated with increased all-cause death at 5 years (69.1%) compared with none or trace AR (48.3%) (P=0.184). Patients with high STS score (>8) had higher mortality rate than those with low STS scores (≤8). The 5-year data from PREVAIL JAPAN show the clinical benefit of TAVR and suggest that balloon-expandable TAVR is an effective treatment option for Japanese patients with severe AS who are not suitable for surgery.

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

Taeniasis and cysticercosis due to Taenia solium in Japan

Directory of Open Access Journals (Sweden)

Yanagida Tetsuya

2012-01-01

Full Text Available Abstract Taenia solium is a zoonotic cestode that causes taeniasis and cysticercosis in humans. The parasite is traditionally found in developing countries where undercooked pork is consumed under poor sanitary conditions and/or as part of traditional food cultures. However, the recent increase in international tourism and immigration is spreading the disease into non-endemic developed countries such as the United States. Although there has been concern that the number of cysticercosis cases is increasing in Japan, the current situation is not clear. This is largely because taeniasis and cysticercosis are not notifiable conditions in Japan and because there have been no comprehensive reviews of T. solium infections in Japan conducted in the last 15 years. Herein, we provide an overview of the status of T. solium infection in Japan over the past 35 years and point out the potential risks to Japanese society.

Operational experiences of INES in Japan

Japan has introduced IAEA's INES in August, 1992. As of September, 1997, the total number of domestic nuclear events which have evaluated by using the INES system has amounted 119. In Japan, when a nuclear event occurs at a nuclear power plant, a provisional evaluation is performed immediately by Nuclear Power Operation Administration Office, MITI. The final evaluation of events is implemented a few months after event occurrence by the Evaluation Committee on Incidents and Failures of Nuclear Power Plant which holds a neutral position. The results of the evaluation are transmitted to IAEA according to the INES reporting criteria

Inaba, Hideo; Maekawa, Keisuke; Koide, Kaoru; Yanagizawa, Koichi

1995-01-01

An extensive study program has been carried out to estimate hydrogeological characteristics of deep underground in Japan. As a part of this program, groundwater flow analysis in Hokkaido and Northeast Japan were conducted. For the analyses of these area, hydrogeological models representing topography, geology, distribution of hydraulic conductivity were developed using available informations from open literature. By use of these models, steady state three-dimensional groundwater flow under a saturated/unsaturated condition was calculated by means of finite element method. The results are as follows: (1) Distribution of piezometric head corresponds with topography in the study area. (2) Piezometric head distribution is hydrostatic below E.L.-1000m in the study area. (3) Hydraulic gradient in the study area is less than 0.04 below E.L.-500m. (4) Difference of boundary conditions at the shore side of these models does not affect the results of the analyses.

As basic information for assessing reactivity and functionality of wetland-associated dissolved organic matter (DOM) based on their composition and structural properties, chemical characteristics of N in ultrafiltered DOM (UDON; > 1 kD) isolated from wetland-associated rivers in three climates (cool-temperate, Hokkaido, Japan; sub-tropical, Florida, USA; tropical, Sarawak, Malaysia) were investigated. The UDON was isolated during dry and wet seasons, or during spring, summer, and autumn. The proportion of UDON present as humic substances, which was estimated as the DAX-8 adsorbed fraction, ranged from 47 to 91%, with larger values in the Sarawak than at the other sites. The yield of hydrolyzable amino acid N ranged 1.24 to 7.01mg g{sup −1}, which correlated positively to the total N content of UDOM and tended to be larger in the order of Florida > Hokkaido > Sarawak samples. X-ray photoelectron N1s spectra of UDON showed a strong negative correlation between the relative abundances of amide/peptide N and primary amine N. The relative abundances of amide/peptide N and primary amine N in the Sarawak samples were smaller (70–76%) and larger (20–23%) respectively compared to those (80–88% and 4–9%) in the Florida and Hokkaido samples. Assuming terminal amino groups and amide N of peptides as major constituents of primary amine N and amide/peptide N, respectively, the average molecular weight of peptides was smaller in the Sarawak samples than that in the Florida and Hokkaido samples. Seasonal variations in UDON composition were scarce in the Sarawak and Florida samples, whereas the distribution of humic substance-N and nonhumic substance-N and compositions of amino acids and N functional groups showed a clear seasonality in the Hokkaido samples. While aromatic N increased from spring to autumn, contributions from fresh proteinaceous materials were also enhanced during autumn, resulting in the highest N content of UDOM for this season. - Highlights: • DON in

Compromised Rivers: Understanding Historical Human Impacts on Rivers in the Context of Restoration

Directory of Open Access Journals (Sweden)

Ellen Wohl

2005-12-01

Full Text Available A river that preserves a simplified and attractive form may nevertheless have lost function. Loss of function in these rivers can occur because hydrologic and geomorphic processes no longer create and maintain the habitat and natural disturbance regimes necessary for ecosystem integrity. Recognition of compromised river function is particularly important in the context of river restoration, in which the public perception of a river's condition often drives the decision to undertake restoration as well as the decision about what type of restoration should be attempted. Determining the degree to which a river has been altered from its reference condition requires a knowledge of historical land use and the associated effects on rivers. Rivers of the Front Range of the Colorado Rocky Mountains in the United States are used to illustrate how historical land uses such as beaver trapping, placer mining, tie drives, flow regulation, and the construction of transportation corridors continue to affect contemporary river characteristics. Ignorance of regional land use and river history can lead to restoration that sets unrealistic goals because it is based on incorrect assumptions about a river's reference condition or about the influence of persistent land-use effects.

The mystery of Japan's missing centenarians explained

2012-03-01

Full Text Available This report elucidates the issue of Japan's missing centenarians, which was uncovered in 2010. We provide the latest figures from verification efforts, discuss sources of centenarian information in Japan, examine possible causes, and evaluate the effect of the missing centenarians on official statistics. In Japan 234,354 people registered before 1910 remained on the family registers in 2010, without being crossed out. They would have been 100 years old at least and represent 0.5Š of the births recorded between 1872 and 1910. The impact of this group on life expectancy statistics, however, is effectively nil.

Miller, Todd W; Omori, Koji; Hamaoka, Hideki; Shibata, Jun-ya; Hidejiro, Onishi

2010-10-01

The Seto Inland Sea (SIS) receives waste runoff from ∼24% of Japan's total population, yet it is also important in regional fisheries, recreation and commerce. During August 2006 we measured carbon and nitrogen stable isotopes of particulate organic matter (POM) and zooplankton across urban population gradients of the SIS. Results showed a consistent trend of increasing δ(15)N in POM and zooplankton from the western to eastern subsystems of the SIS, corresponding to increasing population load. Principal components analysis of environmental variables indicated high positive loadings of δ(15)N and δ(13)C with high chlorophyll-a and surface water temperatures, and negative loadings of low salinities related to inputs from large rivers and high urban development in the eastern SIS. Anthropogenic nitrogen was therefore readily integrated into the SIS food web from primary production to copepods, which are a critical food source for many commercially important fishes.

Geomorphology and river dynamics of the lower Copper River, Alaska

Science.gov (United States)

Brabets, Timothy P.; Conaway, Jeffrey S.

2009-01-01

Located in south-central Alaska, the Copper River drains an area of more than 24,000 square miles. The average annual flow of the river near its mouth is 63,600 cubic feet per second, but is highly variable between winter and summer. In the winter, flow averages approximately 11,700 cubic feet per second, and in the summer, due to snowmelt, rainfall, and glacial melt, flow averages approximately 113,000 cubic feet per second, an order of magnitude higher. About 15 miles upstream of its mouth, the Copper River flows past the face of Childs Glacier and enters a large, broad, delta. The Copper River Highway traverses this flood plain, and in 2008, 11 bridges were located along this section of the highway. The bridges cross several parts of the Copper River and in recent years, the changing course of the river has seriously damaged some of the bridges.Analysis of aerial photography from 1991, 1996, 2002, 2006, and 2007 indicates the eastward migration of a channel of the Copper River that has resulted in damage to the Copper River Highway near Mile 43.5. Migration of another channel in the flood plain has resulted in damage to the approach of Bridge 339. As a verification of channel change, flow measurements were made at bridges along the Copper River Highway in 2005–07. Analysis of the flow measurements indicate that the total flow of the Copper River has shifted from approximately 50 percent passing through the bridges at Mile 27, near the western edge of the flood plain, and 50 percent passing through the bridges at Mile 36–37 to approximately 5 percent passing through the bridges at Mile 27 and 95 percent through the bridges at Mile 36–37 during average flow periods.The U.S. Geological Survey’s Multi-Dimensional Surface-Water Modeling System was used to simulate water-surface elevation and velocity, and to compute bed shear stress at two areas where the Copper River is affecting the Copper River Highway. After calibration, the model was used to examine the

Full Text Available Japan has ratified the 1951 Convention regarding the status of Refugees and the 1967 Protocol relating to the Status of Refugees since 1981 and 1982, yet Japan only accepted an exceptionally low number of refugees in the course 30 years since it ratified the Convention. Japan needs to closely revise and align its national policies with international agreements that it is signatory to. The main framework with which Japan’s government still tackles the issue of refugees is tightly restrained by its overall controlling immigration policies in an attempt to remain a homogenous nation. Japan has a long way to go in order to fully comply with the spirit of the Convention, the Protocol, and international instruments relating to the Status of Refugees. Jepang telah meratifikasi Konvensi Mengenai Status Pengungsi 1951 dan Protokol tentang Kedudukan Pengungsi 1967 sejak tahun 1981 dan 1982, namun Jepang hanya menerima sejumlah kecil pengungsi dalam kurun waktu 30 tahun sejak diratifikasinya konvensi tersebut. Jepang harus meninjau kembali dan memastikan bahwa kebijakan-kebijakan nasional negaranya telah sesuai dengan perjanjian internasional yang telah ditandatangani Jepang. Kerangka kerja pemerintah Jepang dalam menangani isu pengungsi sangat dibatasi oleh berbagai pengetatan kebijakan imigrasi yang dikeluarkan dalam semangat mempertahankan homogenitas bangsa. Jepang memiliki banyak pekerjaan rumah yang harus dilakukan agar dapat memenuhi semangat konvensi, protokol, dan berbagai instrumen internasional terkait status pengungsi.

This paper investigates Momoyama hydraulic power station built on the middle reaches of the Kiso River in Uematsu-cho, Kiso-gun, Nagano Prefecture in Japan, in 1923 by relating to the feature of the building of the hydraulic power station and the architect, Shiro Sato. The hydraulic power station originally was a functional and industrial building which puts a priority on the efficiency of business economy, at the same time it was often required to present a beautiful appearance. The building of Momoyama hydraulic power station was founded on the crane girder structure covered with reinforced concrete(RC) walls. A Hat roof of RC slab was applied to the roof of the building. It was generally designed in Neo-Gothic style. More specifically, however, the wall surface was designed in church style and the upper part was like a castle in the middle ages. Therefore the total design was eclectic. The outer surfaces of the building were remained to be bare concrete as cast. Such a multiple building symbolizes the situation of Japanes architecture in the 1920s. 4 figs.

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

Since about three or four years ago, the enterprises of machinery, iron and steel and welding materials in Japan are paying much attention to the acquisition of ASME (American Society of Mechanical Engineers) certificates or authorization to stamp the code symbols. That is, over 70 factories in Japan have undergone ASME examination, and consequently acquired the authorization or certificates. Such authorization is divided into over 20 kinds, of which about 7 are possessed by the companies in Japan. In nuclear field, the kinds of authorization are N (nuclear vessel), NPT (nuclear vessel parts), NV (nuclear vessel safety valve), and MM (material manufacturing). In non-nuclear fields, they are S (power boilers), U (pressure vessels, in Div. 1), and U2 (pressure vessels in Div. 2). The following matters are described: ASME setup, authorization procedures of ASME for factories, the kinds of authorization, factories in Japan holding the authorization or certificates, and renewal of the authorization.

Full Text Available The author talks about improving victim rights in Japan and his important role in it. A period of Victims’ Renaissance in Japan began in the 1990s when the Japanese Association of Victimology and Mito Victim Assistance Cener, first non-governmental community-based integrated victim support center in Japan were established. Since May 1999 to May 2004, four laws such as “Crime Victim Protection Law”, “Child Abuse Prevention Law”, “Law for Proscribing Stalking Behavior” and so on were enacted and six laws were reformed. The word “rights of victim”, did not appear in any laws. After 2000, the National Association of Crime Victims and Surviving Families (NAVS played an important role. This Association achieved a great success in securing victims a position as the subject of rights. In June 2007, Japan changed the Criminal Procedure Law. This new law will be effective on six months after the day of promulgation. Japanese Government will promulgate it till the end of 2007. Under this new law, crime victims will be allowed to take part in criminal trials, and also make statements during trials.

This paper reports the features and relationships between standardizes nursing terminology sets used in Japan. First, we analyzed the common parts in five standardized nursing terminology sets: the Japan Nursing Practice Standard Master (JNPSM) that includes the names of nursing activities and is built by the Medical Information Center Development Center (MEDIS-DC); the labels of the Japan Classification of Nursing Practice (JCNP), built by the term advisory committee in the Japan Academy of Nursing Science; the labels of the International Classification for Nursing Practice (ICNP) translated to Japanese; the labels, domain names, and class names of the North American Nursing Diagnosis Association (NANDA) Nursing Diagnoses 2003-2004 translated to Japanese; and the terms included in the labels of Nursing Interventions Classification (NIC) translated to Japanese. Then we compared them with terms in a thesaurus dictionary, the Bunrui Goihyo, that contains general Japanese words and is built by the National Institute for Japanese Language. 1) the level of interchangeability between four standardized nursing terminology sets is quite low; 2) abbreviations and katakana words are frequently used to express nursing activities; 3) general Japanese words are usually used to express the status or situation of patients.

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

Valentine, Scott; Sovacool, Benjamin K.; Matsuura, Masahiro

2011-01-01

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

The occurrence of four classes of 17 commonly used antibiotics (including fluoroquinolones, tetracycline, sulfonamides, and macrolides) was investigated in the sediments of the Yellow River, Hai River and Liao River in northern China by using rapid resolution liquid chromatography-tandem mass spectrometry. Higher concentrations were detected for most antibiotics in the sediments of the Hai River than in the sediments of the other rivers. Norfloxacin, ofloxacin, ciprofloxacin and oxytetracycline in the three rivers were most frequently detected with concentrations up to 5770, 1290, 653 and 652 ng/g, respectively. High frequencies and concentrations of the detected antibiotics were often found in the downstream of large cities and areas influenced by feedlot and fish ponds. Good fitted linear regression equations between antibiotic concentration and sediment physicochemical properties (TOC, texture and pH) were also found, indicating that sediment properties are important factors influencing the distribution of antibiotics in the sediment of rivers. - Highlights: > Presence of four classes of commonly used antibiotics in the river sediments. > Higher concentrations in the Hai River than in the Liao River and Yellow River. > Norfloxacin, ofloxacin, ciprofloxacin and oxytetracycline most frequently detected. > High antibiotic concentrations often found in the downstream of large cities. > River sediments are an important reservoir of antibiotics. - Higher concentrations of selected antibiotics were determined in the sediments of the Hai River than in the Liao River and Yellow River.

Why Didn’t “Gangnam Style” Go Viral in Japan?: Gender Divide and Subcultural Heterogeneity in Contemporary Japan

Directory of Open Access Journals (Sweden)

John Lie

2013-12-01

Full Text Available Psy’s “Gangnam Style” was the global pop music and video sensation of 2012, but it failed to go viral in Japan. The involuted nature of the Japanese popular music industry—especially the imperative of indigenization—stunted the song’s dissemination. Simultaneously, the song failed to resonate with its potential base of Japanese K-pop fans, who valorized beauty and romance. In making sense of the Japanese reception of “Gangnam Style,” the author also analyzes the sources of both the Korean Wave and the anti–Korean Wave in Japan.

World's third-largest producer of nuclear power. Japan in need of energy

International Nuclear Information System (INIS)

Japan is the third largest oil consumer in the world behind the United States and China, and the second largest net importer of oil. Japan boasts one of the largest economies in the world. The country continues to experience a moderate economic recovery that began in 2003, following a decade of economic stagnation. Japan's real gross domestic product (GDP) grew by 2.5% in 2005 and 2.3% in 2004. The modest upturn over the last few years reflects higher business confidence in Japan, a surge in export demand led by exports to China, and robust consumer spending. Unemployment in Japan fell to 4.4% in 2005, down from an early 2003 peak of 5.5%. Japan has virtually no domestic oil or natural gas reserves, and in 2005 was the second largest net importer of crude oil in the world. Despite the country's dearth of hydrocarbon resources, Japanese companies have actively pursued upstream oil and natural gas projects overseas. Japan remains one of the major exporters of energy-sector capital equipment, and Japanese companies provide engineering, construction, and project management services for energy projects. (orig.)

Promoting Tourism Destination through Film-Induced Tourism: The Case of Japan

Wadim Strielkowski

2017-01-01

Full Text Available Purpose – This paper describes the marketing potential of film-induced tourism in marketing Japan, as a popular tourism destination for non-Asian visitors. In particular, it focuses on the popular culture and on engaging young people from Europe, America, and Australia in discovering and promoting its cultural heritage. Design/Methodology/Approach – The number of Western tourists to Japan rose by 50 % between 2010 and 2015. Many of these tourists are attracted by the films associated with Japan in one way or another. We assume that, even though the majority of incoming tourists in Japan are Chinese visitors, the marketing potential of film-induced tourism in Japan represents a source of untapped potential. One can trace the increase in the popularity of Japan as the tourism destination to a number of new Western films taking place in Japan. Findings and implications – We employ the monthly data on the combined box office revenues of recent films set in Japan, as well as the monthly statistics on the number of visitors from Australia, Europe, and North America. We find causality between the popularity of the films and the number of tourists from the destinations that are mostly impacted by those films. Limitations – The research is limited by the issue of popularity of Western culture and films in Asia. One should remember that just 3 million out of 19 million foreign tourists that visited Japan in 2015 were non-Asian. Originality – The popularity of films either related to or taking place in Japan is enormous in the Western world. Headed by the recent 2015 Hungarian dark comedy “Liza, the Fox-Fairy”, there is a whole array of films drawing from both exotic and cosmopolitan Japanese culture. The Japanese setting offers a picturesque scenery for melodramas, such as “Lost in translation” (USD 119.7 million in box office revenues or “Memories of a Geisha” (USD 162 million, horrors and thrillers, including “The Grudge” (USD

Cancer incidence and novel therapies developed in Japan

Full Text Available According to the ministry of Health, Labour and welfare of Japan, Cancer has been the leading cause of death in Japan since 1981. [1] As per the data in 2010, in Japan, one in every three deaths was due to cancer. [2] The Japanese Government has introduced so far, three terms of 10 years strategies for Cancer control since 1984 till date. The budget allocated for cancer control in 2009 was 52.5 billion yen in Japan. [3] Lung is the leading site for cancer in both males and females in Japan. In males, following the lung, stomach, liver, colon and pancreas are other leading sites while in the females, stomach, colon, pancreas and breast are the other leading sites.[1] In 2006, the cancer incidence was 694,000 and the male cancer incidence was 1.4 times as large as that of females. The peak age for cancer deaths in males is their fifties while in the females it is the sixties among Japanese. In addition to the conventional treatments such as surgery, radiotherapy and chemotherapy, some of other therapies in practice in Japan are the Hyperthermia [4] that uses high temperatures to kill or damage the cancer cells, the Ion Beam therapy using proton beams [5] to damage the DNA of the cells as cancer cells have high rate of cell divisions and lesser ability to repair DNA damage, the molecular targeted therapies that interfere with a specific molecular target involved in tumour growth and progression [6] and most importantly the autologous cell based Immunotherapies. Modern Cancer Immunotherapy started in the 1970s in Japan. The immunopotentiators using compounds from Bacteria, Beta Glucans from fungi were the first forms of modern Immunotherapy. Then was the era of direct injection of cytokines such as Interleukins, Interferons etc. The adverse effects associated with the injection of cytokines led to development of cell based Immunotherapies in the 1980s. [7] Immuno-cell therapies involve isolation of immune cells which are then processed and re

In 2005, the elderly generation comprised 20% of the Japanese population. This percentage will grow to approximately 30% in 2030, meaning that nearly one in three people in Japan will be 65 years of age or older. Japan is the first nation in the world to face this situation. This article uses the context of Japanese society to give an overview of the elderly and people with disabilities; the International Classification of Functioning, Disability, and Health model; rehabilitation engineering-related policy; and education. In addition, we examine how governmental programs and Japanese law regarding technical aids may evolve by 2030. Partner robots, intelligent powered wheelchairs, nursing robots, and other technologies are introduced as examples of rehabilitation engineering and assistive technology. We also discuss the volunteer activities of the Rehabilitation Engineering Society of Japan (RESJA) in response to the Asian tsunami disaster and the achievements of a group of students from a Japanese senior high school of industry.

In Japan, the Condensed Matter Nuclear Science (CMNS) works have been centering around the Japan CF-Research Society (JCFRS) established in 1999. Recently, about 10 research groups were actively working in the CMNS field, and have been exchanging information mainly in the annual meetings of JCFRS in addition to the International ICCF conferences. For many years efforts have been exclusively devoted to clarification of the underlying physics of excess heat phenomenon and isotopic composition change. Recently, however, an entrepreneur group, Clean Planet Inc., has entered into the CMNS field in Japan, and joined Mizuno to form the above-mentioned group and made a presentation at the LANR/CF Colloquium, at MIT in March 2014. In their work they used glow discharge to form surface nanostructures on nickel mesh wires that are to be subjected to deuterium exposure. They claimed excess power on the order of kilowatts with a coefficient of performance of 1.9. Confirmation of their claim by third parties is highly expected

Review of mental-health-related stigma in Japan.

Ando, Shuntaro; Yamaguchi, Sosei; Aoki, Yuta; Thornicroft, Graham

2013-11-01

The aim of this study is to understand the nature and characteristics of mental-health-related stigma among Japanese people. We searched relevant studies in English or Japanese published since 2001 using MEDLINE and PsycINFO, and found 19 studies that examined mental-health-related stigma in Japan. Regarding knowledge about mental illness, reviewed studies showed that in the Japanese general population, few people think that people can recover from mental disorders. Psychosocial factors, including weakness of personality, are often considered the cause of mental illness, rather than biological factors. In addition, the majority of the general public in Japan keep a greater social distance from individuals with mental illness, especially in close personal relationships. Schizophrenia is more stigmatized than depression, and its severity increases the stigmatizing attitude toward mental illness. The literature also showed an association between more direct social contact between health professionals and individuals with mental illness and less stigmatization by these professionals. Less stigmatization by mental health professionals may be associated with accumulation of clinical experience and daily contact with people who have mental illness. Stigmatizing attitudes in Japan are stronger than in Taiwan or Australia, possibly due to institutionalism, lack of national campaigns to tackle stigma, and/or society's valuing of conformity in Japan. Although educational programs appear to be effective in reducing mental-health-related stigma, future programs in Japan need to address problems regarding institutionalism and offer direct social contact with people with mental illness. © 2013 The Authors.

Nuclear catastrophe in Japan. Health consequences resulting from Fukushima; Atomkatastrophe in Japan. Gesundheitliche Folgen von Fukushima

Energy Technology Data Exchange (ETDEWEB)

Paulitz, Henrik; Eisenberg, Winfrid; Thiel, Reinhold

2013-03-06

On 11 March 2011, a nuclear catastrophe occurred at the Fukushima Dai-ichi nuclear power plant in Japan in the wake of an earthquake and due to serious safety deficiencies. This resulted in a massive and prolonged release of radioactive fission and decay products. Approximately 20% of the radioactive substances released into the atmosphere have led to the contamination of the landmass of Japan with 17,000 becquerels per square meter of cesium-137 and a comparable quantity of cesium-134. The initial health consequences of the nuclear catastrophe are already now, after only two years, scientifically verifiable. Similar to the case of Chernobyl, a decline in the birth rate was documented nine months after the nuclear catastrophe. Throughout Japan, the total drop in number of births in December 2011 was 4362, with the Fukushima Prefecture registering a decline of 209 births. Japan also experienced a rise in infant mortality, with 75 more children dying in their first year of life than expected statistically. In the Fukushima Prefecture alone, some 55,592 children were diagnosed with thyroid gland nodules or cysts. In contrast to cysts and nodules found in adults, these findings in children must be classified as precancerous. There were also the first documented cases in Fukushima of thyroid cancer in children. The present document undertakes three assessments of the expected incidence of cancer resulting from external exposure to radiation. These are based on publications in scientific journals on soil contamination in 47 prefectures in Japan, the average total soil contamination, and, in the third case, on local dose rate measurements in the fall of 2012. Taking into consideration the shielding effect of buildings, the medical organization IPPNW has calculated the collective lifetime doses for individuals at 94,749 manSv, 206,516 manSv, and 118,171 manSv, respectively. In accordance with the risk factors set by the European Committee on Radiation Risk (ECRR) for death

Suicide is a global public health problem and solutions to it can be found only through a global dialog. The suicide rate in Japan has been alarming, but Japan has made substantial efforts to reduce this rate, making prevention a high priority. This report reviews the developmental stages of a comprehensive policy of suicide prevention in Japan from 1998 to 2013. Our review suggests that suicide prevention activities were facilitated by the 2006 Basic Act for Suicide Prevention and the 2007 General Principles of Suicide Prevention Policy. Along with the establishment of a Special Fund program for local governments, the Basic Act and General Principles led to the development of a comprehensive and multi-sector approach to suicide prevention. Suicide rates in Japan, especially among middle-aged men, decreased consistently after 2009, suggesting that the initiatives were effective. Continuous monitoring is needed to evaluate Japan's suicide prevention policy.

Japan, world leader of photovoltaic energy

Since the beginning of the 1970's, the potentialities of photovoltaic energy has been recognized by the Japanese government which has sustained this technology in two ways. First, by the financing of R and D programs, and second, by giving subsidies to citizens for the installation of solar panels. Today, Japan is the world leader of photovoltaic energy, both for the installed power and for the production of solar cells. In 2003, the International Energy Agency was reporting 1.809 GW of worldwide installed capacity among which 48% was in Japan (0.86 GW) with respect to 0.4 GW in Germany, 0.275 GW in the USA and only 20 MW in France. This capacity would have exceeded 1.1 GW at the end of 2004. Half of the solar modules are manufactured in Japan. The ministry of economy, trade and industry (METI) has fixed ambitious goals for 2010: the overall new energy sources much represent 3% of the primary energy (with respect to 1% today) and the installed capacity must reach 4.8 GW. The road-map of the New Energy and Industrial Technology Development Organisation (NEDO) foresees 100 GW by 2030. (J.S.)

Correlations of volcanic ash texture with explosion earthquakes from vulcanian eruptions at Sakurajima volcano, Japan

Miwa, T.; Toramaru, A.; Iguchi, M.

2009-07-01

We compare the texture of volcanic ash with the maximum amplitude of explosion earthquakes ( Aeq) for vulcanian eruptions from Sakurajima volcano. We analyze the volcanic ash emitted by 17 vulcanian eruptions from 1974 to 1987. Using a stereoscopic microscope, we classify the glassy particles into smooth surface particles (S-type particles) and non-smooth surface particles (NS-type particles) according to their surface conditions—gloss or non-gloss appearance—as an indicator of the freshness of the particles. S-type particles are further classified into V-type particles (those including vesicles) and NV-type particles (those without vesicles) by means of examinations under a polarized microscopic of polished thin sections. Cross-correlated examinations against seismological data show that: 1) the number fraction of S-type particles (S-fraction) has a positive correlation with Aeq, 2) the number ratio of NV-type particles to V-type particles (the N/V number ratio) has a positive correlation with Aeq, and 3) for explosions accompanied with BL-type earthquake swarms, the N/V number ratio has a negative correlation with the duration of the BL-Swarms. BL-Swarms refer to the phenomenon of numerous BL-type earthquakes occurring within a few days, prior to an increase in explosive activity [Kamo, K., 1978. Some phenomena before the summit crater eruptions at Sakura-zima volcano. Bull. Volcanol. Soc. Japan., 23, 53-64]. The positive correlation between the N/V number ratio and Aeq could indicate that a large amount of separated gas from fresh magma results in a large Aeq. Plagioclase microlite textual analysis of NV-type particles from five explosive events without BL-Swarms shows that the plagioclase microlite number density (MND) and the L/ W (length/width) ratio have a positive correlation with Aeq. A comparison between textural data (MND, L/ W ratio, crystallinity) and the result of a decompression-induced crystallization experiment [Couch, S., Sparks, R

Full Text Available In the Japanese Islands, small sedentary villages sustained by hunting, gathering, fish- ing and cultivation emerged around 10 000 years ago. This life style of the Jomon people continued for around 7000 years without any drastic changes in material culture, subsistence strategy and vil- lage size until the diffusion of continental civilization into Japan approximately 2500 years ago. This indicates that the incipient sedentary society of the Jomon Period was very stable, a state which is not indicative of civilized society after that time. After the prehistoric situation in Japan, we are able to classify sedentary society into two phases; sedentism with stability and sedentism with instability (civilized society. Therefore it is possible to say that the emergence of sedentism and cultivation are not direct factors which promote the emergence of civilization.

This work analyzes the Japan nuclear policy, in the frame of its foreign and safety policy in Pacific Asia, since the end of the cold war, especially the relations with the Usa and China. The Japan is a civil power because it has submitted the military institution to juridical restrictions and because it does not rely on the armed force to promote its national interests. The anti nuclear speech is joined with the acknowledgement of the dissuasion necessity, of the control of industrial processes and energy channels susceptible of military applications. Cultivating the ambiguity, the Japanese government can send a dissuasive message, perfectly legible, kind of communication of latent intimidation constituted by the virtual nuclear power of a state that takes part to the non proliferation treaty.

Trace elements and radionuclides in the Connecticut River and Amazon River estuary

International Nuclear Information System (INIS)

Dion, E.P.

1983-01-01

The Connecticut River, its estuary, and the Amazon River estuary were studied to elucidate some of the processes which control river water chemistry and the flux of elements to the sea. The approach taken was to identify inputs to the Connecticut River and to investigate geochemical processes which modify the dissolved load. The form and quantity of nuclides which are in turn supplied to the estuary are altered by processes unique to that transition zone to the ocean. The Connecticut River estuary was sampled on a seasonal basis to investigate the role of the estuary in controlling the flux of elements to the sea. The knowledge gained from the Connecticut River study was applied to the quantitatively more significant Amazon River estuary. There a variety of samples were analyzed to understand the processes controlling the single greatest flux of elements to the Atlantic Ocean. The results indicate that estimates of the total flux of nuclides to the oceans can best be calculated based on groundwater inputs. Unless significant repositories for nuclides exist in the river-estuarine system, the groundwater flux of dissolved nuclides is that which will eventually be delivered to the ocean despite the reactions which were shown to occur in both rivers and estuaries. 153 references, 63 figures, 28 tables

Contribution of River Mouth Reach to Sediment Load of the Yangtze River

2015-01-01

Full Text Available This paper examined the sediment gain and loss in the river mouth reach of the Yangtze River by considering sediment load from the local tributaries, erosion/accretion of the river course, impacts of sand mining, and water extraction. A quantitative estimation of the contribution of the river mouth reach to the sediment load of the Yangtze River was conducted before and after impoundment of the Three Gorges Dam (TGD in 2003. The results showed that a net sediment load loss of 1.78 million ton/yr (Mt/yr occurred from 1965 to 2002 in the study area. The contribution of this reach to the sediment discharge into the sea is not as high as what was expected before the TGD. With impoundment of the TGD, channel deposition (29.90 Mt/yr and a net sediment loss of 30.89 Mt/yr occurred in the river mouth reach from 2003 to 2012. The river mouth reach has acted as a sink but not a source of sediment since impoundment of the TGD, which has exacerbated the decrease in sediment load. Technologies should be advanced to measure changes in river channel morphology, as well as in water and sediment discharges at the river mouth reach.

People spend more than two thirds of their daily time indoors. Hence, maintaining a healthy indoor environment is indispensable for the prevention of building related illness. In Japan, guidelines for indoor air quality have been established for 13 volatile/semi-volatile organic compounds (VOCs/SVOCs). These guidelines are now under revision by the Committee on Sick House Syndrome: Indoor Air Pollution. In order to gain information on the current indoor air pollutants and their levels, we carried out a nation-wide survey of VOCs and aldehydes in indoor residential air during 2012-2013. In this review, I concisely summarized the current indoor air quality of Japan.

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

The Japan Sea expeditions at the Japan Atomic Energy Agency (JAEA from October 1, 2005, former JAERI: Japan Atomic Energy Research Institute until September 30, 2005) were started on its participation in the first and second Japanese-Korean-Russian joint expeditions in 1994 and 1995 to investigate the situation on marine pollution due to radioactive wastes dumped in the Japan Sea and other seas around Japan. After the joint expeditions, JAEA continued to conduct the Japan Sea expeditions not only to monitor the impacts of radioactive wastes dumped in the Japan Sea, but also to investigate water circulation and the migration behavior of radionuclides in the Japan Sea. Taking account of some difficulties and constraints due to the political boundaries in the Japan Sea, the expeditions were carried out, separating the sea into two regions; one is the Japanese exclusive economical zone (EEZ) and the other is the Russian EEZ. The data of observations and measurements obtained in the two regions were analyzed together. The program of the Japan Sea expeditions included large-volume seawater sampling at different depths and seabed sediment sampling for measurements of representative anthropogenic radionuclides. To investigate the migration behavior of the radionuclides more in detail, associated oceanographic observations were also implemented; CTD/MBS (conductivity-temperature-depth meter with multi-bottle sampler) casts, analysis of dissolved oxygen and nutrients, deployment and recovery of mooring systems with current meters and sediment traps, and so on. Additional seawater samples were taken with CTD/MBS for further analysis on land. This report summarizes the results of the Japan Sea expeditions (Phase 1) conducted and/or jointed by JAEA from 1994 to 2002. First the report explains oceanographic features of the Japan Sea, main expeditions in the past and the summarized results of the Japanese-Korean-Russian joint expeditions. Then the report gives an outline of the

Japan's Energy and Climate Policy: Towards Dispelling the Uncertainties

Cornot-Gandolphe, Sylvie; Mathieu, Carole

2015-05-01

Four years after the Great East Japan Earthquake and a few months before the opening of the Paris Climate Conference, Japan is about to clarify its energy and climate policy. Already in spring 2014, the Cabinet of Prime Minister Shinzo Abe released the 4. Strategic Energy Plan, drawing the first lessons for the post-Fukushima era. The zero-nuclear scenario was abandoned, although it was established that dependence on nuclear should be as low as possible. Later in 2014, two expert panels were requested to work on quantitative targets for 2030, both in terms of future split between sources for power generation and in terms of greenhouse gas (GHG) emission reduction. The Cabinet's final decisions are expected for June 2015. The draft proposals are already known and suggest that Japan is determined to find a proper balance between system stability, energy security and cost control objectives on the one hand, and the need to reduce domestic GHG emissions on the other hand. Because this task is highly challenging, the government's proposals are unlikely to gain unanimous support, neither domestically nor from the international community. Taking into account the March 2015 decision to decommission five reactors, Japan now has 43 operable nuclear power plants with a capacity of 40.47 GW. Should all of them come back online, their total capacity would be sufficient to meet the draft 2030 target (20-22% share of electricity production), provided that electricity consumption does not rise significantly and that the lifetime of the nuclear plants is extended to 60 years. Although the approved restart of some nuclear units is a milestone for Japan's nuclear industry and energy mix, there are still uncertainties around the scale and timing of the restart, in particular because of the local opposition. Japan aims at increasing the share of renewable electricity production, which is set to reach 22-24% in 2030. Such target does not seem particularly ambitious, knowing that the

Formation rate of water masses in the Japan Sea

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

Outlook for coal and air quailty legislation in Japan

Nagata, Nobuo

1992-01-01

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

River and Reservoir Operations Model, Truckee River basin, California and Nevada, 1998

2001-01-01

The demand for all uses of water in the Truckee River Basin, California and Nevada, commonly is greater than can be supplied. Storage reservoirs in the system have a maximum effective total capacity equivalent to less than two years of average river flows, so longer-term droughts can result in substantial water-supply shortages for irrigation and municipal users and may stress fish and wildlife ecosystems. Title II of Public Law (P.L.) 101-618, the Truckee?Carson?Pyramid Lake Water Rights Settlement Act of 1990, provides a foundation for negotiating and developing operating criteria, known as the Truckee River Operating Agreement (TROA), to balance interstate and interbasin allocation of water rights among the many interests competing for water from the Truckee River. In addition to TROA, the Truckee River Water Quality Settlement Agreement (WQSA), signed in 1996, provides for acquisition of water rights to resolve water-quality problems during low flows along the Truckee River in Nevada. Efficient execution of many of the planning, management, or environmental assessment requirements of TROA and WQSA will require detailed water-resources data coupled with sound analytical tools. Analytical modeling tools constructed and evaluated with such data could help assess effects of alternative operational scenarios related to reservoir and river operations, water-rights transfers, and changes in irrigation practices. The Truckee?Carson Program of the U.S. Geological Survey, to support U.S. Department of the Interior implementation of P.L. 101-618, is developing a modeling system to support efficient water-resources planning, management, and allocation. The daily operations model documented herein is a part of the modeling system that includes a database management program, a graphical user interface program, and a program with modules that simulate river/reservoir operations and a variety of hydrologic processes. The operations module is capable of simulating lake

Hydrogeological investigations of river bed clogging at a river bank filtration site along the River Warta, Poland

Full Text Available River bank filtration (RBF is a system that enriches groundwater resources by induced infiltration of river water to an aquifer. Problematic during operation of RBF systems is the deterioration of infiltration effectiveness caused by river bed clogging. This situation was observed in the Krajkowo well field which supplies fresh water to the city of Poznań (Poland during and after the long hydrological drought between the years 1989 and 1992. The present note discusses results of specific hydrogeological research which included drilling of a net of boreholes to a depth of 10 m below river bottom (for sediment sampling as well as for hydrogeological measurements, analyses of grain size distribution and relative density studies. The results obtained have allowed the recognition of the origin of the clogging processes, as well as the documentation of the clogged parts of the river bottom designated for unclogging activities.

Desapriya, E B R; Iwase, Nobutada; Shimizu, Shinji

2003-02-01

Tobacco use, particularly smoking, remains the number one cause of preventable disease and mortality in Japan. This review of the tobacco control policy and public health is the first to offer a composite review of the subject within Japan. This review attempts to evaluate the most important aspects of the current political economy of the tobacco control policy, and concludes that more effective control policies must be employed to minimize the impact of smoking on the public's health in Japan. Further the article attempts to place the approaches in the larger context of tobacco control, providing a vision for the future of tobacco prevention and control based on current knowledge. Tobacco use will remain the leading cause of preventable illness and death in Japan, until tobacco prevention and control efforts are commensurate with the harm caused by tobacco. Taken together, the results of various studies have clearly shown that control measures can influence tobacco smoking patterns, and in turn, the rate of tobacco-related problems. Government tobacco taxes have not kept pace with inflation for years. Availability of tobacco is virtually unlimited with easy access and the prices being very low due to the strong currency of Japan. Thus Japan must be one of the most tobacco accessible countries. It is important to ensure that people are not conditioned to smoke tobacco by an unduly favourable economic and commercial environment. For that reason, prevention advocates have called for substantial regulation of tobacco products and appeal for both tobacco tax increases and tobacco taxes to be indexed to inflation. In this review, present tobacco related public health policies in Japan are discussed with implication for prevention of tobacco related problems. Continued research in this area will be necessary to determine the most effective policies of reducing tobacco related problems in Japan.

Analyses of CO2 emissions embodied in Japan-China trade

This paper examines CO 2 emissions embodied in Japan-China trade. Besides directly quantifying the flow of CO 2 emissions between the two countries by using a traditional input-output (IO) model, this study also estimates the effect of bilateral trade to CO 2 emissions by scenario analysis. The time series of quantifications indicate that CO 2 emissions embodied in exported goods from Japan to China increased overall from 1990 to 2000. The exported CO 2 emissions from China to Japan greatly increased in the first half of the 1990s. However, by 2000, the amount of emissions had reduced from 1995 levels. Regardless, there was a net export of CO 2 emissions from China to Japan during 1990-2000. The scenario comparison shows that the bilateral trade has helped the reduction of CO 2 emissions. On average, the Chinese economy was confirmed to be much more carbon-intensive than Japan. The regression analysis shows a significant but not perfect correlation between the carbon intensities at the sector level of the two countries. In terms of CO 2 emission reduction opportunities, most sectors of Chinese industry could benefit from learning Japanese technologies that produce lower carbon intensities.

Development of nuclear powered ship in Japan

Sato, Hiroshi

1976-01-01

The development of nuclear merchant ship in Japan was started in 1955 by the establishment of Nuclear Ship Study Group, and since then, the investigation, test and research on nuclear ships have been continued. As a result, a nuclear ocean observation and supply ship was designed for trial. Researches were carried out also in JAERI and Institute for Technical Research of Ships. Meanwhile, the nuclear icebreaker Lenin was completed in Soviet Union in 1959, the nuclear ship Savannah set out for maiden voyage in U.S. in 1962, and the construction of the nuclear ore carrier Otto Hahn was prepared in FRG. Japan Nuclear Ship Development Corp. was established in 1963, and started the design and construction of the first nuclear ship in Japan, Mutsu. The basic policy in the construction is the improvement of nuclear ship technology, the securing of safety, and the use of domestic technologies as far as possible. The progress of the design, construction and test of the Mutsu is described. Owing to the problem of radiation leak, the development of nuclear ships stagnated for a while, but the nuclear plant of the Mutsu demonstrated the expected performance in the functional test, land criticality test and zero output test, and it is expected that the bud of the independent development brought up so far can bear valuable fruit. The independent development of marine nuclear reactors should be continued by selecting the way most suitable to Japan. (Kako, I.)

Post-Fukushima Japan: The continuing nuclear controversy

The Fukushima disaster was a wake-up call for the nuclear industry as well as a shocking revelation of the inner workings of the Japanese power sector. The political fallout from the event was far-reaching, pushing governments into abandoning nuclear expansion, turning instead to fossil fuels and renewable energy alternatives. While the move away from nuclear energy was deemed a move critical to political survival in Europe, we find that political candidates running on anti-nuclear platforms did not win elections, while the pro-nuclear Liberal Democratic Party won government in the 2012 elections. Against this backdrop, we analyse the energy conflict in Japan using a framework of values versus interests and consider the regulatory and cultural conditions that contributed to the disaster. A number of considerations lie in the way of an organised phase-out of nuclear power in Japan. We also consider the possible policy paths Japan may take. - Highlights: • As Europeans urgently phase-out nuclear power, Japan voted out such a government despite high anti-nuclear sentiment. • Regulatory climate within the nuclear industry was dysfunctional as a result of being captured by the ‘nuclear village’. • New ‘independent’ nuclear authority is made up of previously captured agency. • With a pro-nuclear government, and lack of really independent nuclear authority, old problems may yet arise. • Japanese government has to choose between lowering emissions, low popular support for nuclear power, and affordable electricity

Military aspect of nuclear policy of Japan

Military aspect of nuclear policy of Japan was outlined. In 1952 Prime Minister Yoshida asked to prepare production of weapons for rearmament and to establish Science and Technology Agency such as to overcome lack of science research budget and inefficiency of research and cooperation. Kaya and Fushimi proposed establishment of Atomic Energy Commission as recommendation of Science Council of Japan. In 1954 Nakasone proposed budget for nuclear energy with yen 235 million to construct reactor. In 1955 Japanese delegation participated in international conference on peaceful use of nuclear energy at Geneva and nonpartisan members proposed Atomic Energy Basic Law, which limited the use of nuclear technology to peaceful purposes, ensured three principles - democratic methods, independent management, and transparency - as the basis of nuclear research and promoted international co-operation. In 1956 Atomic Energy Commission and Science and Technology Agency were established with other organizations under this law. According to internal report in the age of Prime Minister Sato, nuclear policy in Japan would be (1) no holding nuclear weapon for the time being, (2) maintaining economic and technical potential of nuclear weapon production and (3) considering no restraint for this policy whether Japan participated in NPT or not. Fuel cycle program of Monju reactor and reprocessing for power production seemed to be deployed corresponding to (3) above. Irradiated blanket of Monju reactor could be reprocessed to produce highly purified plutonium suited for nuclear bombs. (T. Tanaka)

Investing in river health.

Science.gov (United States)

Bennett, J

2002-01-01

Rivers provide society with numerous returns. These relate to both the passive and extractive uses of the resources embodied in river environments. Some returns are manifest in the form of financial gains whilst others are non-monetary. For instance, rivers are a source of monetary income for those who harvest their fish. The water flowing in rivers is extracted for drinking and to water crops and livestock that in turn yield monetary profits. However, rivers are also the source of non-monetary values arising from biological diversity. People who use them for recreation (picnicking, swimming, boating) also receive non-monetary returns. The use of rivers to yield these returns has had negative consequences. With extraction for financial return has come diminished water quantity and quality. The result has been a diminished capacity of rivers to yield (non-extractive) environmental returns and to continue to provide extractive values. A river is like any other asset. With use, the value of an asset depreciates because its productivity declines. In order to maintain the productive capacity of their assets, managers put aside from their profits depreciation reserves that can be invested in the repair or replacement of those assets. Society now faces a situation in which its river assets have depreciated in terms of their capacity to provide monetary and non-monetary returns. An investment in river "repair" is required. But, investment means that society gives up something now in order to achieve some benefit in the future. Society thus has to grapple wih the choice between investing in river health and other investments--such as in hospitals, schools, defence etc. - as well as between investing in river health and current consumption--such as on clothes, food, cars etc. A commonly used aid for investment decision making in the public sector is benefit cost analysis. However, its usefulness in tackling the river investment problem is restricted because it requires all

The Use of Oral Histories to Identify Criteria for Future Scenarios of Sustainable Farming in the South Yangtze River, China

Directory of Open Access Journals (Sweden)

Pingyang Liu

2016-08-01

Full Text Available Agricultural practices in Jiangnan water towns have historically been identified as maintaining a balance between human activity and the local environment, but are now a significant local source of water pollution. Using a multi-methods approach, this study deduces the environmental impact of traditional practices, and the socially desired conditions for successfully reintroducing critical ones. Oral histories from 31 farmers in Tianshanzhuang village, South Yangtze River were in order to chart changes in farming practices over four historic periods, and used to estimate the nitrogen and phosphorus burdens per acre. Findings show that the use of Lan River Mud—dredged mud for fertilizer—was key in producing a positive impact, but abandoned after the 1980s. Four criteria hindering reintroduction of traditional practices were identified, and potentially useful but fragmented emerging local candidate practices are considered against these, as are recent practices in Japan. We propose that the cooperation of several stakeholders with various related government departments in China could lead to a portfolio of effective policy changes and should be studied further: to include new methods and uses of Lan River Mud; the integration of aquaculture, leisure and tourism industries with agriculture; and the production of organic produce with well-planned internet-linked sales, delivery and coordination mechanisms.

Tritium ((3)H) concentrations were measured in groundwater samples from four surface wells (4-10 m deep), four shallow wells (24-26.5 m deep) and a 150-m-deep well in the Futamata River catchment area, which is adjacent to the large-scale commercial spent nuclear fuel reprocessing plant in Rokkasho, Japan. The (3)H concentrations in most of the surface- and shallow-well samples (<0.03-0.57 Bq l(-1)) were similar to those in precipitation (annual mean: 0.31-0.79 Bq l(-1)), suggesting that the residence time of the water in those wells was 0-15 y. The (3)H concentrations in the samples from a 26-m-deep well and the 150-m-deep well were lower than those in the other wells, indicating that groundwater with a long residence time exists in deep aquifers and the estuary area of the catchment. It is not clear whether (3)H released during test operation of the plant with actual spent nuclear fuel affected the (3)H concentrations observed in this study. © The Author 2015.

2015-09-01

Full Text Available We applied a river habitat quality (RHQ assessment method to the Hai River Basin (HRB; an important economic centre in China; to obtain baseline information for water quality improvement; river rehabilitation; and watershed management. The results of the assessment showed that the river habitat in the HRB is seriously degraded. Specifically; 42.41% of the sites; accounting for a river length of 3.31 × 104 km; were designated poor and bad. Habitat in the plain areas is seriously deteriorated; and nearly 50% of the sites; accounting for a river length of 1.65 × 104 km; had either poor or bad habitats. River habitat degradation was attributable to the limited width of the riparian zone (≤5 m; lower coverage of riparian vegetation (≤40%; artificial land use patterns (public and industrial land; frequent occurrence of farming on the river banks and high volumes of solid waste (nearly 10 m3; single flow channels; and rare aquatic plants (≤1 category. At the regional scale; intensive artificial land use types caused by urbanization had a significant impact on the RHQ in the HRB. RHQ was significantly and negatively correlated with farmland (r = 1.000; p < 0.01 and urban land (r = 0.998; p < 0.05; and was significantly and positively correlated with grassland and woodland (r = 1.000; p < 0.01. Intensive artificial land use; created through urbanization processes; has led to a loss of the riparian zone and its native vegetation; and has disrupted the lateral connectivity of the rivers. The degradation of the already essentially black rivers is exacerbated by poor longitudinal connectivity (index of connectivity is 2.08–16.56; caused by reservoirs and sluices. For river habitat rehabilitation to be successful; land use patterns need to be changed and reservoirs and sluices will have to be regulated.

Eosinophilic Chronic Rhinosinusitis in Japan

Directory of Open Access Journals (Sweden)

Junichi Ishitoya

Full Text Available ABSTRACT: Chronic rhinosinusitis is a heterogeneous disease. In Europe and the United States, it has recently been divided into two subgroups: chronic rhinosinusitis with nasal polyps (CRSwNP and chronic rhinosinusitis without nasal polyps (CRSsNP. The majority of CRSwNP cases have a strong tendency to recur after surgery and show eosinophil-dominant inflammation. However, this definition has proved difficult to apply in Japan and East Asia, because more than half of the CRSwNP cases do not exhibit eosinophil-dominant inflammation in these areas of the world. In Japan in the 1990s, refractory CRSwNP to the standard treatment was focused on in clinical studies and the term ''eosinophilic chronic rhinosinusitis'' (ECRS was introduced to identify this subgroup of chronic rhinosinusitis in 2001.ECRS is different from non-ECRS in terms of many clinical features: symptom appearance, occurrence site of nasal polyps, CT scan findings, the histology of nasal polyps, blood examination findings, clinical course after surgery, and co-morbid asthma, etc. In this review, we describe these clinical features and mention how to make a clinical diagnosis of ECRS as well as how to treat it. Finally, we discuss the pathophysiology of ECRS. The concept of ECRS in Japan would be applicable for CRSwNP in other countries including Europe and the United States.

Japan after the Quake: Prospects for climate policy

Luta, Alexandru

2011-01-01

The triple calamity of 11 March 2011 has dealt a serious blow domestically to the credibility of the Japanese nuclear industry, putting the country's energy policy in flux.The severe impact on the country's infrastructure, the unwieldiness of its bureaucracy and the chaotic political situation preclude Japan's energy policy from explicitly re-orientating itself before the middle of 2012, but political consensus seems to be emerging that the country's mid-term pledge on emission reductions will need to be curtailed.The bill on renewable energy passed under Prime Minister Kan marked a step in the right direction, but was shallow and politically opportunistic. Its future impact on policy is uncertain.With other policy instruments on climate proposed by the Democratic Party of Japan toothless or abandoned, Tokyo's ability to engage in significant mitigation activities domestically is in question.Opposition to a second commitment period to the Kyoto Protocol remains firm; Japan will continue to pursue bilateral mechanisms outside the UNFCCC framework.Given its frail domestic policy and a stated readiness to act internationally outside multilateral frameworks, Japan's promise to carry out significant mitigation activities even in the absence of a clear and comprehensive post-2012 legal instrument should be viewed with a critical eye.(Author)

Return of vitrified wastes from France to Japan

International Nuclear Information System (INIS)

2000-01-01

The radioactive wastes resulting from the burnup of nuclear fuels in nuclear reactors represent 3 to 5% of the spent fuel. These wastes cannot be reused nor recycled and thus are vitrified after reprocessing. Japanese power companies have signed contracts with Cogema in France and BNFL in the UK for the reprocessing of their spent fuels. Then, the ultimate reprocessed wastes are sent back to Japan for storage. This information dossier takes stock of different questions relative to the transport of the vitrified wastes from France to Japan: why France sends back containers of vitrified wastes to Japan? What is a vitrified wastes container made of? How containers are transported? What is the regulatory frame applicable to these transports? Which safety measures are taken during transport? Which physical protection is applied? Which temporary storage facilities are used before and after transportation? How is performed the ultimate storage of wastes in Japan? Which quality and safety warranties are taken? Which emergency plans and exercises are provided? What are the applicable civil liability regimes? And what kind of information is given to the public about these transports. Some general information about energy and nuclear power worldwide, energy and environment, radioactivity, BNFL, Cogema and ORC is given in appendixes. (J.S.)

This keynote paper deals with: energy issues and nuclear power development in Japan, problems of radiation protection, licensing and safety regulations, research on LOCA and ECCS, stress corrosion cracks related to pressure vessels, nuclear fuel failures, steam generators, incidents, waste management and fuel cycle facilities. In conclusion it is stated that: on order to cope with global matters vitally affecting the electricity generation, taking into consideration Japanese specific energy issues, the nuclear power development has been an indispensable policy of Japan. In order to proceed with further development of nuclear power plants, it is necessary to obtain proper understanding by the public, showing assurance of the safety and reliable operation of nuclear power plants through daily plant operation. The nuclear safety issues should be considered from a global point of view. It is necessary to establish common safety standards which could harmonize the safety level of nuclear power plants in the world. The safety goal concerning severe accidents should be established as an internationally agreeable one. Japan has accumulated highly technological experience in maintenance of nuclear power plants. It is believed that the cumulative experiences in Japan can contribute to the further improvement of safety of nuclear power plants throughout the world, and for this aim a mutual information exchange should be encouraged

Two years have elapsed since the accident in Chernobyl nuclear power station shocked those concerned with nuclear power generation. The effect that this accident exerted on human environment has still continued directly and indirectly, and the reports on the effect have been made in various countries and by international organizations. In Japan, about the exposure dose of Japanese people due to this accident, the Nuclear Safety Commission and Japan Atomic Energy Research Institute issued the reports. In this report, the available data concerning the envrionmental radioactivity level in Japan due to the Chernobyl accident are collected, and the evaluation of exposure dose which seems most appropriate from the present day scientific viewpoint was attempted by the detailed analysis in the National Institute of Radiological Sciences. The enormous number of the data observed in various parts of Japan were different in sampling, locality, time and measuring method, so difficulty arose frequently. The maximum concentration of I-131 in floating dust was 2.5 Bq/m 3 observed in Fukui, and the same kinds of radioactive nuclides as those in Europe were detected. (Kako, I.)

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

Japan steps up overseas pace to compensate for nuclear doldrums at home

Shepherd, John

2015-01-01

The recent re-election of Japan's prime minister Shinzo Abe is seen by many commentators as a largely positive move, in terms of political support for a slow revival of Japan's commercial nuclear fortunes. But Japan's nuclear companies cannot expect a return to 'business as usual' anytime soon and so have set their sights on overseas markets. The government has supported Japan's industrial giants as they renew efforts to enter foreign markets, such as Vietnam and Turkey. It is hardly surprising to note that this move is not popular with some environmentalists and opposition politicians. Critics argue that Japan is not best-placed to be selling its nuclear know-how and technologies elsewhere in the light of the Fukushima-Daiichi disaster. But those critics fail to acknowledge advances made since plants such as Fukushima-Daiichi were built in the 1960ies. A report released by Japan's Institute of Energy Economics (IEE) towards the end of last December showed why nuclear firms desperately need to tap business opportunities overseas.

A goal of the 21. century is for society to pursue 'sustainable economic development and prosperous life by recycling resources', thus rejecting 'development based on the waste of resources'. For Japan, which has limited energy resources, it is important to secure safe, inexpensive, environmentally friendly energy resources having long-term availability. To contribute to long-term energy security and solve global environmental issues, and to create advanced competitive science and technology, the Japan Atomic Energy Agency (JAEA) was established by integrating the Japan Atomic Energy Research Institute (JAERI) and the Japan Nuclear Cycle Development Institute (JNC) in October 2005. JAEA is endeavoring to establish nuclear fuel cycles, to contribute to social improvement through hydrogen production initiated by atomic energy, and to pursue research and development of thermonuclear fusion and quantum beam technology. This paper reviews the main R and D activities of JAEA. The structure of the paper is the following: 1. Introduction; 2. Japan Atomic Energy Agency; 3. Efforts to Commercialize the Fast Reactor Cycle; 4. Monju Progress; 5. Geological Disposal of High-Level Radioactive Waste R and D; 6. High Temperature Gas-Cooled Reactor System R and D; 7.

Around the margins of the Pacific Ocean, denser oceanic plates slipping under continental plates cause subduction earthquakes generating large tsunami waves. The subducting Pacific and Philippine Sea plates create damaging interplate earthquakes followed by huge tsunami waves. It was a rupture of the Japan Trench subduction zone (JTSZ) and the resultant M9.0 Tohoku-Oki earthquake that caused the unprecedented tsunami along the Pacific coast of Japan on March 11, 2011. EQECAT's Japan Earthquake model is a fully probabilistic model which includes a seismo-tectonic model describing the geometries, magnitudes, and frequencies of all potential earthquake events; a ground motion model; and a tsunami model. Within the much larger set of all modeled earthquake events, fault rupture parameters for about 24000 stochastic and 25 historical tsunamigenic earthquake events are defined to simulate tsunami footprints using the numerical tsunami model COMCOT. A hybrid approach using COMCOT simulated tsunami waves is used to generate inundation footprints, including the impact of tides and flood defenses. Modeled tsunami waves of major historical events are validated against observed data. Modeled tsunami flood depths on 30 m grids together with tsunami vulnerability and financial models are then used to estimate insured loss in Japan from the 2011 tsunami. The primary direct report of damage from the 2011 tsunami is in terms of the number of buildings damaged by municipality in the tsunami affected area. Modeled loss in Japan from the 2011 tsunami is proportional to the number of buildings damaged. A 1000-year return period map of tsunami waves shows high hazard along the west coast of southern Honshu, on the Pacific coast of Shikoku, and on the east coast of Kyushu, primarily associated with major earthquake events on the Nankai Trough subduction zone (NTSZ). The highest tsunami hazard of more than 20m is seen on the Sanriku coast in northern Honshu, associated with the JTSZ.

The GSJ is the main supporting organization of IYPE Japan, which is an implementation body of IYPE in Japan, serving as its secretariat. During the IYPE triennial activity, the GSJ has been supporting development of Geparks, establishment of "the Geology Day" and the Earth Science Olympiad activities with some academic societies, and has distributed geological maps with IYPE logo. The GSJ also established an outreach network "Geo-networks Tsukuba" as a local legacy of the IYPE, and has managed it with a local government, research organizations, nonprofit corporations and local media to increase geological and environmental literacy of public, especially among young people. The GSJ-AIST has also contributed internationally to IYPE by joining two international projects, OneGeology and the CCOP Book project. Geoparks in Japan are characterized by following features. The Japanese Islands and the surrounding seas are situated in the area of unique geologic features; the place where several tectonic plates meet and collide. This causes earthquakes and volcanic activities, and makes Japan one of most dynamic areas on the earth. The dynamics of the earth bring about not only geological hazards but also a lot of blessings. In August of 2009, three Geoparks, the Toya Caldera and Usu Volcano Geopark, the Itoigawa Geopark and the Unzen Volcanic Area Geopark, were accepted to join the Global Geopark Network from Japan for the first time. Since its launch in 2006, the GSJ has been playing a major role in promoting Geoparks in Japan together with Geological Society of Japan. The GSJ hosts the Japan Geopark Committee (JGC) for quality evaluation, serving as the information center of Geoparks in Japan. The Geology Day of Japan (10th of May) has been set up by the academic societies for geology in Japan and GSJ in 2007. The Geology Day is expected to provide the chances for the public to enjoy field trips and excursions and to understand the importance of geo-diversity. The Day

Climate Change Policy Measures in Japan: NEDO's Activities to Promote CDM/JI

The Kyoto Protocol, which obliges developed countries to reduce emissions of greenhouse gases (GHG), was adopted at the third session of the conference of the parties to the United Nations Framework Convention on Climate Change (UNFCCC) in Kyoto, Japan, on I I December 1997. Japan subsequently ratified the Kyoto Protocol in 2002 and is required thereunder to reduce GHG emissions by 6% below 1990 levels by 2008-2012. Japan, having already tackled development and promotion of energy conservation technologies after the second oil crisis, emits the lowest level of CO 2 of developed countries approximately 9.4 tons per capita in the year 2000. Consequently, Japan is able to contribute to CO 2 emissions reduction in developing economies as well as in economies in transition by application of Japan's energy conservation technologies. Because the Clean Development Mechanism (CDM) and Joint implementation (JI) of the Kyoto Mechanisms are efficient tools, the Japanese government's policy towards emission reduction makes active use of CDM/JI, thereby supporting domestic efforts in realizing Japan's reduction commitment. The Ministry of Economy, Trade and Industry (METI) of Japan is one of the key ministries to administer Governmental policy making on climate change, and is undertaking establishment of a system to facilitate the Kyoto Mechanisms. The New Energy and Industrial Technology Development Organization (NEDO), under the jurisdiction of METI, supports CDM and JI project activities implemented by Japanese private sector enterprises. In this report, the authors briefly introduce climate change policy measures in Japan and NEDO's activities to promote CDM/Jl. (Author)

Legalized abortion in Japan.

Science.gov (United States)

Hart, T M

1967-10-01

The enactment of the Eugenic Protection Act in Japan was followed by many changes. The population explosion was stemmed, the birth rate was halved, and while the marriage rate remained steady the divorce rate declined. The annual total of abortions increased until 1955 and then slowly declined. The highest incidence of abortions in families is in the 30 to 34 age group when there are four children in the family. As elsewhere abortion in advanced stages of pregnancy is associated with high morbidity and mortality. There is little consensus as to the number of criminal abortions. Reasons for criminal abortions can be found in the legal restrictions concerning abortion: Licensing of the abortionist, certification of hospitals, taxation of operations and the requirement that abortion be reported. Other factors are price competition and the patient's desire for secrecy. Contraception is relatively ineffective as a birth control method in Japan. Oral contraceptives are not yet government approved. In 1958 alone 1.1 per cent of married women were sterilized and the incidence of sterilization was increasing.

Food irradiation in Japan

Ito, Hitoshi

1995-01-01

The basic research on food irradiation in Japan was begun around 1955 by universities and national laboratories. In 1967, food irradiation was designated to the specific general research on atomic energy, and the national project on large scale was continued until 1983. As the result, the treatment of germination prevention for potatoes was approved by the Ministry of Health and Welfare in 1972. The Co-60 gamma ray irradiation facility of Shihoro Agricultural Cooperative is famous as the facility that succeeded in the practical use of food irradiation for the first time in the world. But the practical use of food irradiation stagnates and the research activities were reduced in Japan due to the circumstances thereafter. The effect of radiation to foods and living things is explained. The features of the radiation treatment of foods are small temperature rise, large transmissivity, no residue, the small loss of nutrition and large quantity, continuous treatment. The safety of irradiated foods is explained. The subjects for hereafter are discussed. (K.I.)

Denitrification in the Mississippi River network controlled by flow through river bedforms

Science.gov (United States)

Gomez-Velez, Jesus D.; Harvey, Judson W.; Cardenas, M. Bayani; Kiel, Brian

2015-01-01

Increasing nitrogen concentrations in the world’s major rivers have led to over-fertilization of sensitive downstream waters1, 2, 3, 4. Flow through channel bed and bank sediments acts to remove riverine nitrogen through microbe-mediated denitrification reactions5, 6, 7, 8, 9, 10. However, little is understood about where in the channel network this biophysical process is most efficient, why certain channels are more effective nitrogen reactors, and how management practices can enhance the removal of nitrogen in regions where water circulates through sediment and mixes with groundwater - hyporheic zones8, 11, 12. Here we present numerical simulations of hyporheic flow and denitrification throughout the Mississippi River network using a hydrogeomorphic model. We find that vertical exchange with sediments beneath the riverbed in hyporheic zones, driven by submerged bedforms, has denitrification potential that far exceeds lateral hyporheic exchange with sediments alongside river channels, driven by river bars and meandering banks. We propose that geomorphic differences along river corridors can explain why denitrification efficiency varies between basins in the Mississippi River network. Our findings suggest that promoting the development of permeable bedforms at the streambed - and thus vertical hyporheic exchange - would be more effective at enhancing river denitrification in large river basins than promoting lateral exchange through induced channel meandering. 

FBR/VHTR deployment scenarios in Japan

Richards, Matt; Kunitomi, Kazuhiko

2008-01-01

Co-deployment of Fast Breeder Reactors (FBRs) and Very High Temperature Reactors (VHTRs) can be used as the nuclear technologies to meet a significant portion of Japan's future energy demands. The FBR provides the fissile fuel for energy security and sustainability, and can be used to provide a significant portion of the electricity demand. The VHTR can provide flexible energy outputs (electricity, hydrogen, and high-temperature heat) with high efficiency, can operate with a wide variety of fuel cycles, and can be sited at locations that have limited availability of cooling water. These features, combined with its passive safety and high degree of proliferation resistance, make the VHTR an ideal complement for co-deployment with the FBR in Japan and also a very low-risk technology of export to foreign countries. In addition to hydrogen production, the high-temperature thermal energy produced by the VHTR fleet can be used for a wide variety of process-heat applications, and the VHTR can play a key role for significantly reducing greenhouse-gas emissions. This paper describes assessments for deploying FBRs and VHTRs in Japan using a closed fuel cycle, with the FBRs supplying the fissile material to sustain the combined FBR/VHTR fleet. (author)

2006-01-01

In order to identify the concentration of tritium ( 3 H) in areas of fresh, brackish and sea water, bordered by nuclear fuel facilities at Rokkasho-Village, Aomori, Japan, water samples were collected from 2001 to 2004 at six points in those areas. Concentration ranges of tritium in fresh river water, brackish lake and seawater samples were 0.60 to 1.1 Bq x l -1 (mean value 0.79 Bq x l -1 ), 0.20 to 0.87 Bq x l -1 (mean value 0.41 Bq x l -1 ), and 0.08 to 0.25 Bq x l -1 (mean value 0.15 Bq x l -1 ), respectively. Relationships between tritium concentrations and salinity in the samples showed a clear negative correlation. Moreover, the seasonal variation of tritium in water from Rokkasho-Village was high in spring and low in fall. (author)

Water management through dams and reservoirs is worldwide necessary to support key human-related activities ranging from hydropower production to water allocation, and flood risk mitigation. Reservoir operations are commonly planned in order to maximize these objectives. However reservoirs strongly influence river geomorphic processes causing sediment deficit downstream, altering the flow regime, leading, often, to process of river bed incision: for instance the variations of river cross sections over few years can notably affect hydropower production, flood mitigation, water supply strategies and eco-hydrological processes of the freshwater ecosystem. The river Po (a major Italian river) has experienced severe bed incision in the last decades. For this reason infrastructure stability has been negatively affected, and capacity to derive water decreased, navigation, fishing and tourism are suffering economic damages, not to mention the impact on the environment. Our case study analyzes the management of Isola Serafini hydropower plant located on the main Po river course. The plant has a major impact to the geomorphic river processes downstream, affecting sediment supply, connectivity (stopping sediment upstream the dam) and transport capacity (altering the flow regime). Current operation policy aims at maximizing hydropower production neglecting the effects in term of geomorphic processes. A new improved policy should also consider controlling downstream river bed incision. The aim of this research is to find suitable modeling framework to identify an operating policy for Isola Serafini reservoir able to provide an optimal trade-off between these two conflicting objectives: hydropower production and river bed incision downstream. A multi-objective simulation-based optimization framework is adopted. The operating policy is parameterized as a piecewise linear function and the parameters optimized using an interactive response surface approach. Global and local

Japan`s balance in environmental-oriented water resources management is contradictory. Some improvements have been achieved, for instance in the treatment of industrial discharges and, in particular, in reducing emissions of toxic heavy metals. Conversely, with other forms of pollution, such as the organic load, no progress has been made so far; in some instances the situation has even deteriorated. However, measures for an advanced protection of waters are planned. New construction, extension, and modernization of wastewater treatment plants are a priority objective in environmental policy. A positive impact on water quality can be expected when the implementation of an emission-charges system for industries and the development of sewerage systems for households, based on the polluter-pays-principle, will be completed.

2016-06-01

Full Text Available Interferometric Synthetic Aperture Radar (InSAR technique is able to detect a slope deformation around landslide (e.g., Singhroy et al., 2004; Une et al., 2008; Riedel and Walther, 2008; Sato et al., 2014. Geospatial Information Authority (GSI of Japan has been performing the InSAR analysis regularly by using ALOS/PALSAR data and ALOS-2/PALSAR-2 data throughout Japan. There are a lot of small phase change sites except for crustal deformation with earthquake or volcano activity in the InSAR imagery. Most of the phase change sites are located in landslide area. We conducted field survey at the 10 sites of those phase change sites. As a result, we identified deformation of artificial structures or linear depressions caused by mass movement at the 9 sites. This result indicates that InSAR technique can detect on the continual deformation of landslide block for several years. GSI of Japan will continue to perform the InSAR analysis throughout Japan. Therefore, we will be able to observe and monitor precursory slope deformation around landslide areas throughout Japan.
