Based on a time series of ocean climate indices and catch records for seven pelagic fish species in the Tsushima Warm Current (TWC) and Kuroshio-Oyashio Current (KOC) regions from 1910 to 2004, we detected regional synchrony in the long-term fluctuations of the fish populations and identified alternation patterns of dominant species related to climate shifts. The annual catches of Pacific herring, Japanese sardines, Japanese anchovies, jack mackerel, chub mackerel, Pacific saury and common squid in the TWC region fluctuated in phase with those in the KOC region, which suggests that they were controlled by the same basin-wide climate forcing. After the collapse of the herring fishery, the alternation sequence was: sardines (1930s), Pacific saury, jack mackerel, common squid and anchovies ($1950s{\sim}1960s$), herring ($late\;1960s{\sim}early\;1970s$), chub mackerel (1970s) and then sardines (1980s). As sardine biomass decreased in the late stages of the cool regime, catch of the other four species increased immediately during the warm period of the 1990s. Regional differences in the amplitude of long-term catch fluctuations for the seven pelagic fishes could be explained by regional differences in availability, fishing techniques and activity.

Eighty-five different cultivars of Brassica rapa, B. juncea, B. nap us, B. carinata, B. oleracea and hexaploid Brassica collected from Bangladesh, Japan, China and Denmark were analyzed by SDS-PAGE for seed and leaf protein variations, using esterase, acid phosphatase and peroxidase isozyme analysis. Ten polymorphic bands were identified from seed protein however no identifiable polymorphic band was found in the leaf protein. Polymorphic markers clearly distinguished the different Brassica species as well as yellow sarson (YS) and brown seeded (BS) cultivars of B. rapa. The $F_1$ cross between YS and brown seeded cultivars showed the existance of all poly-morphic bands of the respective parents. The Bangla-deshi and Japanese cultivars of B. rapa differed in the amount of seed protein. In the case of isozyme analysis, esterase showed the highest number of polymorphic bands (13) followed by acid phosphatase (9) and peroxidase (5). These polymorphic markers were very effec-tive for classification of all the species studied in this experiment. In parentage tests using isozymes, the hybridity of intra-and-interspecific crosses of almost all the seedlings could be identified from their respective cross combinations. Esterase polymorphism showed a clear differentiation between YS and BS types of B. rapa. In addition, two esterase polymorphic markers were iden ified to differentiate some cultivars of B. juncea. Segregation patterns in these two esterase bands showed a simple Mendelian monohybrid ratio of 3:1 in $F_2$, 1:1 in test cross and 1:0 in back cross progenies. No polymorphic band was identified to distinguish different cultivars of the same species by acid phosphatase or peroxidase. Polymerase Chain Reaction (PCR) was carried out with seed coat color specific marker of B. juncea. The yellow seeded cultivars produced a strong band at 0.5 kb and weak band 1.2 kb. In the addition of these two specific bands, Japanese yellow-seeded cultivars expressed two more weak bands at 1.0 kb and 1.1 kb. Where the brown seeded cultivars generated a single strong band at 1.1 kb. In segregating population, the yellow seed coat color marker segregated at a ratio 15 (brown) : 1 (yellow), indicating the digenic inheritance pattern of the trait.

Background: International organizations such as the World Health Organization (WHO) and the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) reported public exposure doses due to radionuclides released in the Fukushima nuclear accident a few years after the event. However, the reported doses were generally overestimated due to conservative assumptions such as a longer stay in deliberate areas designated for evacuation than the actual stay. After these reports had been published, more realistic dose values were reported by Japanese scientists. Materials and Methods: The present paper reviews those reports, including the most recently published articles; and summarizes estimated effective doses (external and internal) and issues related to their estimation. Results and Discussion: External dose estimation can be categorized as taking two approaches-estimation from ambient dose rate and peoples' behavior patterns-and measurements using personal dosimeters. The former approach was useful for estimating external doses in an early stage after the accident. The first 4-month doses were less than 2 mSv for most (94%) study subjects. Later on, individual doses came to be monitored by personal dosimeter measurements. On the basis of these measurements, the estimated median annual external dose was reported to be < 1 mSv in 2011 for 22 municipalities of Fukushima Prefecture. Internal dose estimation also can be categorized as taking two approaches: estimation from whole-body counting and estimation from monitoring of environmental samples such as radioactivity concentrations in food and drinking water. According to results by the former approach, committed effective dose due to ¹³⁴Cs and ¹³⁷Cs could be less than 0.1 mSv for most residents including those from evacuated areas. Conclusion: Realistic doses estimated by Japanese scientists indicated that the doses reported by WHO and UNSCEAR were generally overestimated. Average values for the first-year effective doses for residents in two affected areas (Namie Town and Iitate Village) were not likely to reach 10 mSv, the lower end of the doses estimated by WHO.

This Study is purposed to comparative analysis in the case of balanced with Ethnic image fashion and the event of an unbalanced between fashion and make-up and to reconfigure on the make-up of the features on the Ethnic image Fashion in the 21st century. The result of this study is as follows. First, in the case of Japanese ethnic image make-up, to emphasize applied forms and formative characterization, they generally use circles and horizontal lines. Also the harmony between Japanese image make-up and primary colors like white and red strengthen ethnic images better. In the event of an unbalance between fashion and image make-up, fashion occurs dynamically in Africa and linearly in China. Sexy & natural image make-up also widely appear in the modern view. Second, in the case of African ethnic make-up balanced with African image fashion, the form is repeatedly dotted, widely water-colored, and mattedly textured using ash make-up colors such as white, red, gold, gray and so forth. African image make-up strongly expresses primitive natural beauty adding primal tribal painting art and mask forms. In case of an unbalance between fashion and image make-up, no distinctive ethnic image make-up appears. To emphasize natural patterns as well as splendid & decorative fashion, they try not to use primary colors, but instead focus on natural make-up and monotone colored point make-up, sexy make-up, avant-garde make-up, goth make-up, romantic make-up, glossy make-up.

The object of this research is to take a bilateral look into cultural exchanges of the Netherlands and Japan through the East India Company and thereby improve the general understanding in regards to the exchanges of costume cultures between the East and the West. The study conducted qualitative analyses on features of contemporary costumes of the Netherlands and Japan from 1602 to 1799 by investigating the secondary sources, such as the histories of costumes, arts, and literature. The results are as follows; the traditional sleeves of the Japanese Kimono were basically cut out in a straight line. However due to the growing popularity of the kimono home gown in Europe, the producers of the kimono in India as well as several other European countries modified them into western-style sleeves. Regarding the costumes of the Netherlands, which were introduced to Japan, the study found that Japan imported Dutch fabrics, instead of specific clothing items. In Japan, costume controls and anti-conspicuous consumption regulations among social classes including a closed-door policy had negative effects on both developments and exchanges of costumes of the country. However, when it comes to the Jinbaori, a costume for ruling classes, Japan was open to using fabrics, patterns and designs of the West. In light of what have been discussed so far, the study confirmed that the costume exchanges between the two countries started long after their first business of the general cultural exchanges. Though it is clear that the advancements in the natural sciences that the Japanese made can be attributed to the West, Japan was one of the nations that impacted the costume cultures in Europe.

Objectives: Environmental pollution is a significant global issue. Both objective (scientifically measured) environmental pollution and perceived levels of pollution are important predictors of self-reported health. The purpose of this study was to compare the associations between perceived environmental pollution and health in China, Japan, and South Korea. Methods: Data were obtained from the East Asian Social Survey and the Cross-National Survey Data Sets: Health and Society in East Asia, 2010 (n=7938; China, n=3866; Japan, n=2496; South Korea, n=1576). Results: South Koreans perceived environmental pollution to be the most severe, while Japanese participants perceived environmental pollution to be the least severe. Although the Japanese did not perceive environmental pollution to be very severe, their self-rated physical health was significantly related to perceived environmental pollution, while the analogous relationships were not significant for the Chinese or Korean participants. Better mental health was related to lower levels of perceived air pollution in China, as well as lower levels of perceived all types of pollution in Japan and lower levels of perceived noise pollution in South Korea. Conclusions: Physical and mental health and individual socio-demographic characteristics were associated with levels of perceived environmental pollution, but with different patterns among these three countries.

This study aims to shed light on the diversity and complexity of design represented through modern fashion and to identify growth opportunities for globalizing and modernizing traditional clothing designs. To this end, formative trends and aesthetic characteristics of $21^{st}$ century fashion were analyzed, with an emphasis on Japanism reflected in the works of Western designers. The research methodology consisted of an analysis as well as a literature review. A total of 217 designs with Japanism characteristics were identified from the 2001 S/S collection to the 2011 S/S collection in Paris, Milano, New York, and London, and these were analyzed in terms of image, color details, pattern, and accessories. The research findings with regard to the characteristics of modern fashion designs that reflect Japanism were as follows. First, sensuality was projected by highlighting the erotic elements of Japanese clothing. Second, the underlying principles, styles, and elements of Japan's traditional clothing were embodied in a cross-cultural and eclectic manner that blurred the boundaries between styles by mix-and- matching the traditional and the contemporary, the East and the West, and different styles. Third, a variety of patterns, colors, accessories, and design techniques associated with Japanese traditional clothing played a critical role in creating flamboyant and decorative images in contemporary fashion. Fourth, the overlapping of the kimono style, the flat design that accentuates body curves, and the layered style has created a beautifully free-form fashion that demonstrates non-structural features.

The purpose of this study is to review the influence of Ukiyo-e on the design of European Paintings of the $19^{th}$ century and the expression of the design of Kosode design in Edo-era. We collected data from the actual study of visiting Museums and other theories and visual materials through literature review. Then, we analyzed the data. The result came out that Ukiyo-e, which is the genre painting of Edo-era, provided the new vision and the new way of expression to the European Paintings of the $19^{th}$ century. In the same way, the result also indicated that Ukiyo-e similarly influenced on the design of Kosode. For example, the study showed that the patterns of Kosode, such as flower, bridge, fun, wave, Lotus flower, stripe, oval, plaid, were used in the works of European artists in the $19^{th}$ century. The Ukiyo-e styles include Kan Bun style, Dan-Gawari style, Back facing style, Two-Section Segmentation style, and Folding screen style, with the identity of Japan and Japanese unique nature and landscapes. Thus, this study proved the design of Kosode to be the frontier of both European and Japanese arts, by examining Ukioyo-e's plastic characteristics, its composition & arrangements, and its subjects & objects which were samely revealed in Kosode design and European Art in nineteenth century.

Jeonju-Jang is the wood furniture that was made in Chonbuk Jeonju province during the Joseon Dynasty, and was used by middle-upper social classes. It has value as a local cultural heritage because it has unique characteristics in terms of the shape of the furniture, the metal ornament and various functions are integrated in accordance with user's requirements. Therefore, the purpose of this study is to define the structural characteristics of the Jeonju-Jang through case studies of 16 existing artifacts in order to preserve and inherit the value as local cultural resources. The conclusion is as follows. First, Jeonju-Jang in the late period of Joseon Dynasty that is made up of one board to the bottom with the binding of the board. and the front wall, the Juibyuckkan and the Meoruemkan are omitted or made small, so the structure of the surface is simple. There are three or four drawers under the Cheon pan(top plate). There are drawers and shelf inside the hinged door. In the case of a two-layer type, there is a Gaegumeong type door which has half of one side hinged. Second, Jeonju-Jang of the Japanese Ruling Era had a Juibyuckkan by frame binding and an increase in the number of Meoruemkan. and it had independent legs. The Cheon-pan(top plate) was more left and right than both sides. Third, in the late Joseon Dynasty period as a feature of the metal ornaments, cast iron and yellow brass were used as materials. In the Japanese Ruling Era, nickel was mainly used. Various patterns were engraved and the number increased, and it became gorgeous surface as a whole.

전동차의 유지보수를 위한 철도차량기지는 신선 건설시 계획되거나 리모델링을 하고 있다. 하지만, 차량기지를 건설할 때 검수시설 규모를 산정하는데 검수규정에 의해 설계를 하고 있으나 명확한 기준이나 표준방안이 설정되어 있지 않다. 차량기지의 설계규모 산정 시 설계기준이나 규모산정의 여유율 등은 대부분 일본의 사례를 참조하여 설계되고 있는 실정이다. 일반적으로 검수공정은 그 프로세스가 정형화 되어있다. 따라서 이러한 프로세스를 보다 세분화하고 검증이 이루어진다면 표준안이 마련될 수 있을 것이다. 본 연구는 정형화되어 있는 검수 프로세스를 BPR기법을 적용하여 Modeling하고, 실제 국내 철도차량기지의 중수선공장의 검수공정 Layout을 토대로 공정분석 및 시뮬레이션 기법을 통하여 검수 용량을 검증하고자 한다. 또한, 이 자료를 기반으로 한 시뮬레이션 결과를 기존에 사용하였던 여유율(파동율)의 적정수준 및 적용방향을 제시하고자 한다.
