This study investigated the devoicing rate of Japanese high vowels, focusing on regional and generational differences by acoustically analyzing vowels from two large speech databases. The first speech database used in this study was collected between 1986 and 1988 from 41 areas (prefectures) which included 607 participants (299 high school students and 308 their grandparents). The second was taken from a 2006-2007 collection from seven areas as a follow-up investigation to the first database consisting of 463 participants ranging in age from 8-90 year olds. The results revealed there is a generational as well as regional difference in the devoicing rate in almost all areas. Based on those results, a new distribution map reflecting a current devoicing rate of the younger generation was presented. Furthermore, by comparing the two data sets, this study confirmed age difference in the devoicing rate is not age-grading but a sound change in progress. This study discusses the social factors for changes in the devoicing rate of some areas and then applies the devoicing rate of five areas to an S-curve model to predict the future devoicing rate.

The history of occupational health in Korea s covered the era of the Republic of Korea after the Liberation from the Japanese colonialism. But the number of Korean workers exceeded about 2 millions at the times of liberation in 1945, so that it is expected that many occupational health problems inflicted Korean workers under the Japanese colonialism. The authors reviewed medical literatures, administrative documents, and other available data which were published under the colonial state, and collected things which had reference to the health status of Korean workers. The results were as follows : 1. Nutritional status of Korean workers was supposed to be inferior to that of general population, some students, and poor inhabitants in a remote mountain villages. 2. It was supposed that the constitution of Korean workers was near lower limit of average build of contemporary Koreans. 3. The accidents rate in mines was significantly high but decreasing year after year, and the most important cause of accidents was the fall of roof in the mine. The medical facilities and equipments for miners were supposed to be not sufficient in the mines and workshops. 4. Some occupational disease including silicosis, noise-induced hearing impairment, and decompression disease were known. But, overall incidence or prevalence of these diseases could not be identified. 5. On the whole, the fatalities of acute infectious diseases of Korean workers were higher than those of Japanese inhabitants in Korea and Korean inhabitants. The prevalence of pulmonary tuberculosis of Korean workers was increasing with every passing year. 6. The medical personnels and facilities were so deficient that most Korean workers were out of adequate medical use. We discussed only a part of the health status of Korean workers under the Japanese colonialism, so it would be necessary to have a better grasp of details of occupational health policy and health status in the era of afflicting.

In this study, an externally reinforced structural system for SMC(Sheet Molding Compound) panel water tank, designed according to the Japanese design code, is experimented to evaluate its seismic performance. The test tank is 3m long, 2m wide and 3m high, considering the capacity and size of the shaking table. The measured hydrodynamic pressures are found to be approximately 70% of the Japanese design code values. It may be partially due to the convex shape effect of the unit panels. The analytical results of externally reinforced system based on the measured dynamic water pressures are found in good agreement with the test results. If the design hydrodynamic pressures are estimated properly, the proposed analytical model for the externally reinforced water tank becomes a useful design tool and the Japanese design code is found to provide a safe design for the external frames of SMC panel water tank.

Background/Aims: Mechanical properties (MPs) and axial and radial force (AF and RF) may influence the efficacy and complications of self-expandable metallic stent (SEMS) placement. We measured the MPs of various SEMSs and examined their influence on the SEMS clinical ability. Methods: We evaluated the MPs of 29 types of 10-mm SEMSs. RF was measured using a conventional measurement device. AF was measured using the conventional and new methods, and the correlation between the methods was evaluated. Results: A high correlation in AFs was observed, as measured by the new and conventional manual methods. AF and RF scatterplots divided the SEMSs into three subgroups according to structure: hook-and-cross-type (low AF and RF), cross-type (high AF and low RF), and laser-cut-type (intermediate AF and high RF). The hook-and-cross-type had the largest axial force zero border (>20°), followed by the laser-cut and cross types. Conclusions: MPs were related to stent structure. Hook-and-cross-type SEMSs had a low AF and high axial force zero border and were considered safest because they caused minimal stress on the biliary wall. However, the increase in RF must be overcome.

Accurate ocean surface fluxes with high resolution are critical for understanding a mechanism of global climate. However, it is difficult to derive those fluxes by using ocean observation data because the number of ocean observation data is extremely small and the distribution is inhomogeneous. On the other hand. satellite data are characterized by the high density, the high resolution and the homogeneity. Therefore, it can be considered that we obtain accurate ocean surface by using satellite data. Recently we constructed ocean surface data sets mainly using satellite data. The data set is named by Japanese Ocean Flux data sets with Use of Remote sensing Observations (J-OFURO). Here, we introduce J-OFURO. The data set includes shortwave radiation, longwave radiation, latent heat flux, sensible heat flux, and momentum flux etc. Moreover, sea surface dynamic topography data are included in the data set. Radiation data sets covers western Pacific and eastern Indian Ocean because we use a Japanese geostationally satellite (GMS) to estimate radiation fluxes. On the other hand, turbulent heat fluxes are globally estimated. The constructed data sets are used and shows the effectiveness for many scientific studies.

The purpose of this research is to analyze the preference of Korean food and the satisfaction level with the service of Korean restaurants for Japanese and Chinese students in Korea. Self administered questionnaires were collected from 204 Japanese and Chinese students in Korea. The data were statistically analysed using t-tests, one-way ANOVA and their correlation. The most preferred Korean foods were Bulgogi, Kimgui, Haemul-pajun, Kalbi-tang, Bibimbap, Youkgaejang, Ssalbap, and Aehobarkjeon, in that order. Female students liked Korean food more than male students (p＜0.05), and Japanese students more than Chinese students (p＜0.001). of foreign students, 44.3％ replied that they had teamed about Korean food at school, and 34.48％ tried to cook Korean food at home. The foreign students answered that hygiene and cleanness were the most important factors to be improved for Korean restaurant. Other factors to be improved are the variety of menus, price level, taste, service, atmospheres, and quantity, in that order. Korean restaurants should strive to provide a high level of service and improved quality of Korean food, not only to foreign students, but also to other foreigners and tourists to present good image of Korea.

본 연구는 일본 고등학교 지리역사과 학습지도요령과 지리 교과서를 대상으로 하여 한국 관련 내용의 선정 근거 및 서술의 특징을 분석한 것이다. 학습지도요령에서는 두 세 개의 '근린제국(이웃국가)'을 선정하여 그들의 생활 문화를 일본과 비교하여 유사성과 차이를 이해 존중할 수 있도록 하고 있다. 근린제국과 관련한 지역학습이 생활 문화에 초점을 둠으로써 자연환경 내용은 이들에 영향을 주는 요인으로서 일부 다루어지고 있을 뿐이다. 독도는 대부분 분쟁 가능 지역으로 기술하고 있지만, 일부 교과서에는 시마네현의 영토로 명기하거나, 지도상에 일본의 영토로 표기 한 사례도 있다. 한국의 독특한 생활 문화로는 문자로서 한글, 사상으로서 유교, 종교로서 불교와 기독교, 의식주로서 한복, 쌀과 국, 불고기와 가위, 숟가락과 젓가락, 온돌 등에 대해 삽화를 곁들여 자세하게 기술하고 있다. 그리고 한일 교류와 관련하여서는 정치 경제적 교류보다는 최근에 활발하게 이루어지고 있는 예술과 스포츠 분야 교류에 초점을 두고 있다. 이와 같이 일본의 지리 교과서는 주로 생활과 문화에 초점을 둠으로써 인간이 중심이 된 지리를 실현하고 있을 뿐만 아니라, 사례 지역과 일본과의 상호 비교를 통한 유사성과 차이에 초점을 둠으로써 지식과 이해의 성장뿐만 아니라 이타심과 공감적 이해의 발달을 가능하게 하고 있다. 이는 세계화 및 다문화 시대에 요구되는 대안적인 지역학습의 사례를 보여주고 있다고 할 수 있다.
