Objectives: This study was performed in order to compare the average levels and similarity of occupational exposure limits in South Korea, the U.S., the E.U., Germany, Japan and Finland. Methods: In this study, occupational exposure limits (OELs) for one hundred and seventy seven hazardous substances which are managed in the workplace by the Occupational Safety and Health Act in South Korea were matched with those of other countries. The units for the exposure limits of the same substance (identical CAS number) were unified and the exposure limits in each country were compared with threshold limit values (TLVs) of the American Conference of Governmental Industrial Hygienists (ACGIH) using a geometric mean method. Geometric similarity was calculated to assess the association by each country. Results: The exposure limits according to ACGIH TLVs in South Korea, the E.U., Germany, Japan, and Finland were 148, 37, 76, 90, and 110, respectively. When using TLVs of ACGIH as a standard, the geometric mean ratios of Germany, Finland, the E.U., South Korea, and Japan were 0.79, 0.80, 0.82, 1.19, and 1.27, respectively. Geometric similarity with TLVs of ACGIH was highest in South Korea (0.75) followed by Japan (0.56), the E.U. (0.52), Finland (0.50), and Germany (0.46). Conclusions: Through the comparison of levels of OELs and similarities among South Korea, the U.S., the E.U., Germany, Japan, and Finland, we could better understand the characteristics of occupational exposure limits by country.

In this paper, we analyze time data (i.e., new moon time, sunrise and sunset times, twenty-four seasonal subdivision times, and so forth) in the Japanese astronomical almanacs between 1885 and 1943. During this period, two types of astronomical almanacs were published in Japan; Honreki (本曆; Formal Almanac) and its simplified version, Ryakuhonreki (略本曆). We use mainly the latter almanac for analyzing the time data. It is also known that Japan introduced the Gregorian calendar in 1873, adopted the standard meridian of $135^{\circ}E$ in 1888, and used Tokyo Observatory (東京天文臺; $139^{\circ}$ 44' 30" E and $35^{\circ}$ 39' 15" N) as the reference position of time data since 1891. We verify those facts and investigate the accuracy of time data in Japanese almanacs by comparing the data with the results of modern calculations. In this study, we present our findings.

History of the fisheries education in the secondary schools in Japan has began in 1901, and it greatly contributed to the development of fishing industry in Japan. Also this education system affected to her some neighboring countries. e.g. Korea, Taiwan, etc. According to the fundamental change of the education system after cease of the 2nd World War, fisheries middle schools were rearranged to fisheries high schools. and the activity of the graduates widely contributed to push up the total catch of fish in Japan to the first world rank since the 1970s. Nevertheless, the education in fisheries high schools is confronted to much problems, because of the rapid decrease of the man power who desires to work in the field of fisheries especially onboard fishing vessels in accordance with the rapid progress of industrialization and service economization. Such problems are taking place not only in Japan but also right now in Korea. To find out some countermeasure against the problems. the auther studied on the present status and the problems confronting in the education of fisheries high schools in Japan through some references. with heartful desires this study to be able to contribute to the sucessive development of the education on fisheries high schools and also the productivity of fisheries in Korea.

The purpose of this research starts analyzing the case with the United States and Japan and considering the plan form of educational facilities in the advanced country for the improvement of educational facilities in our counties. Japan was managing the educational system which carried out homogeneous till the first stage of the 1970s like advanced nations, such as the educational system of the industrialization age before World War II, i.e., Britain and the United States. The form of an American open school was adopted after the second half of the 1960s, trying the educational system which also globalized the educational system of Japan while the world went into the information society. In the process of the introduction, Japan did not simply imitate a huge open space in the United States. Japan selected the content of the education carefully. And, to do an original educational activity by guidance. The current classroom and multipurpose space were planned as one body. As a result, the environment of the classroom was able to do various studying patterns of individual study and the group study.

Experimental investigations of interlaminar mechanical properties for carbon fiber reinforced plastic (CFRP) laminates were carried out using aramid fiber ($Kevlar^{(R)}$-29 1000d) and carbon fiber (TR40-1K 612d, Mitsubishi Rayon) stitching. Various carbon fiber (CF) stitch densities were used to prepare a number of CF stitched CFRP laminates for double cantilever beam (DCB) tests. An insert tongue-type loading fixture, developed by the Japan Aerospace Exploration Agency (formerly the National Aerospace Laboratory of Japan), was also employed in the DCB test. Interlaminar tension tests were carried out under an out-of-plane directional loading using a single CF stitch thread in the CFRP laminates. The DCB test results clarified that the relationship between the volume fractions of the CF stitch thread ($V_{ft}$) and mode I critical energy release rate ($G_{Ic}$) showed a mostly linear function with a higher gradient than that of the $Kevlar^{(R)}$ stitched CFRP laminates. The CF stitched CFRP tension test results indicated that the consumption energy per unit area ($E_i$) was larger than that of $Kevlar^{(R)}$ stitched CFRP laminates.

The reasons for studying the case of Japan are as follows. First, the increases in the aged population is similar to the case of Korea, and consumers are aging as the population ages. Second, the structure of industry in Japan is very similar to Korea, which describes the fact that the share of the manufacturing industry decreases but the service industry (e.g., medicine, finance, and insurance) increases. Third, Japan is considered as the best predictive model for forecasting the future of closed schools in Korea because the GNI gross income per capita is relatively close to the one of Korea among the several neighboring countries. The purpose of this study is to analyze the current extent of utilizing closed schools in Japan and, based on the analysis, to provide basic data on the use of closed schools in Korea in the future. The types of closed schools can be classified into education facilities, social welfare facilities, cultural facilities, public sports facilities, income growing facilities, and others. Based on the classification, the analyses of the characteristics of each type for the facilities are presented. and When the utilization status of closed schools in Japan is analyzed, 363 schools were utilized (51.4%) in 2003, means the lowest utilization rate of the target year, after that 4198 schools (70.6%) were utilized in 2015. The utilization ratio is steady increased.

The focus of this paper is to critically evaluate the contemporary health promotion policy of g Korea and Japan. The primary purpose of this comparative research project is to stimulate policy debate and to strengthen the design and implementation of evidence-based policies that improve population health and reduce health related disparities. For the purpose of the research object we adopted analysis of health promotion(HP) sources. The HP Source which is still under development in Europe, is a potentially valuable tool for global use. This European Commission funded project lead by the London School of Hygiene and Tropical Medicine has brought together organisations from all of the European Union Member States, plus Norway, Iceland, Latvia, Switzerland and the Czech Republic to contribute their data. The findings of this research will be conclude by making recommendations for further comparative studies and in particular how EUHPID and the HP Source tool and database can be expanded for use at global level through the IUHPE. The result as follows: 1. The Health Promotion Act enacted 1995 in Korea and 2000 in Japan. The government has a national document on HP titled Health Plan 2010 and Healthy Korea 2010 in Korea and Healthy Japan 21 in Japan. 2. The Health Plan 2010 of Korea contains 14 goals, i.e. life expectancy, smoking, nutrition, mental health, dental health, reproductive health, hypertension, cerebrovascular diseases, arthritis, diabetes mellitus, cardiovascular diseases, and cancer. It should be emphasized that the Korean HP national document adds 3 goals of health expectancy, reproductive health, and arthritis to its Japanese counterpart. Health Plan 2010 of Korea specifies 37 objectives in 14 goals, and Healthy Japan 21 proposes 48 objectives and 80 targets in 9 goals. 3. Health Plan 2010 and Healthy Japan 21 have not been evaluated yet, and no regular systematic monitoring reporting of HP policies is available in Korea and Japan yet. 4. National Health Promotion Fund is a financial source of HP programs at the national level in Korea. Its annual amount is 736 billion Won(equivalent to approximately 640 million US$), otherwise no specific Health Promotion Fund in Japan.

Global Flood Alert System (GFAS) is an attempt to make the best use of satellite rainfall data in flood forecasting. The project of GFAS is promoted both by Ministry of Land, Infrastructure and Transport-Japan (MLIT) and Japan Aerospace Exploration Agency (JAXA), under which Infrastructure Development Institute-Japan (IDI) has been working on the development of Internet-based information system and just launched trial run of GFAS in April 2006 on International Flood Network (IFNet) website. The function of GFAS is to connect space agencies and hydrological services/river authorities in charge of flood forecasting and warning by providing global rainfall information in maps, text data e-mails and so on which is produced from binary global rainfall data downloaded from National Aeronautics and Space Administration (NASA) website. Although the effectiveness of satellite rainfall data in flood forecasting and warning has yet to be verified, satellite rainfall is expected to play an important role to strengthen existing flood forecasting systems by diversifying hydrological data source.

So far, the Japanese exhibitions in the colonized Korea, especially the Joseon Industrial Exhibition of 1915, haven't been studied sufficiently; they have been understood mainly as political propaganda to legitimize the Japanese colonization of the Korean peninsula; many scholars have agreed that Japan highlighted material developments in Korea under the benevolent guidance of Japan by displaying strong visual contrasts between the modern and the traditional. So, they only acknowledge colonial modernity; this perspective regards Western forms as the sole expression of architectural modernity, not only in the exhibition but also in the colonial space and time. However, to be on a par with the West, Japan started to develop a series of historical narratives in searching for its historical origins in Asia, and it also carried out archaeological investigations in the Korean peninsula around the early 1900s. I argue that the developed historical narratives with traditional Korean artworks and architecture (i.e. the shared historical origins between Japan and Korea) influence the architectural conditions of the 1915 exhibition. And, the status of traditional Korean architecture in the Japanese exhibition expresses architectural modernity in terms of showing historical progress.

To promote liquid crystal application of nanoimprint lithography, a polymer with new concept is proposed. The material consists of a polyamic acid for good LC alignment and an epoxy resin for good imprinting. The result of sum-frequency generation (SFG) vibrational spectroscopy proves that this material is a functionally gradient material. This material shows excellent capability as a nanoimprinting material as well as an LC alignment layer.
