As the trend of ship's automation has spreaded over from 1950's , it caused shipping industries to develop new concept of ship's officer to operate new type of ships with high technologies. As a result, French started the education of Dual Purpose Officer (DPO) from 1967 for mariners who has skills and knowledge in navigation and engineering area. these experiments were concerned mainly with an improved carrier structure for officers, efficiency in ship's operation and subsequent cost saving, and in these years, many advanced countries in shipping business have been interested in the DPO system and adopted it especially in the Northern Europe and Japan. In Jorea there were researches for DPO based on experience of those in foreign countries in the middle of 1980's and established it with revision of relevant domestic regulation in 1990. Korean shipping industry will meet first graduates from DPO program in the near future but it seems that there were not sufficient studies to prepare actual practice. In the paper it was tried to analyze korean DPO system in the structure of education and certification by comparing them with foreign one and found that curriculums of the two maritime universites in Korea are quite suitable under circumstances of domestic shiping industry but some amendments are needed in relevant regulations.

In 2007, in the city of Chongqing, the city government announced a plan to meet the basic needs of its lower-to-middle class residents, namely those of providing a shelter and urban infrastructure. In one respect, the effort to attain such goals has achieved good quantitative results; however, a more critical examination reveals that little consideration has been given to analyzing the qualitative aspects of such a policy, namely the physical and emotional effects on tenants. The results of the research in this paper have implications on the need to focus on building a 'sustainable' and 'healthy' community, with the awareness that for people in low-rent areas, sociability and community spirit are more closely related to their neighborhood contentment. Although attention to scale and type of area-planning are both important, the immediate surroundings and services are often neglected, but as we shall show they are key considerations for residents in this new type of housing. While attempting to comprehend the role of community in the quality of a neighborhood, in this research, we attempt to document the physical appearance of the problem and explore its underlying causes in order to shed more light on residents' individual evaluations of quality in their local living conditions and include the affective dimensions of such perceptions.

This investigation is to question as to whether and how much urban residential superblocks have changed the uses of facilities, as compared with original zoning plan. The difference between the original plan for 'land use' in 1960's and current 'building uses' has been examined on six superblocks in Seoul, and the reasons for change were analyzed. Investigation results are as follows: As the original urban planning was intended for use-purification by the subdivision of zones in a superblock through zoning, current buildings uses are different from the land-use. Commercial facilities are located in residential zone along community paths because of the necessity, and business buildings are placed on the appropriate-sized lots in the middle of residential blocks, due to the need of small and low-rent offices. Also, different types of residence have been built on convenient locations in commercial zone to meet various housing needs. In conclusion, the current zoning system plays a role of controling the volume of buildings rather than the use of land. Therefore, mixed use of land, not functional separation, becomes a natural phenomenon taken place in the contemporary cities, and it is high time to adopt a mixed-use zoning system.

Functional school planning has long been considered a fundamental concept of school design. However. in planning educational facilities, it is also important to include the dimensions of comfort, convenience and healthfulness. The school lavatories and drinking fountains are one of most crucial elements for the recent changing face in healthful school design, but the number of lavatories and drinking fountains in most schools may not be sufficient to meet current needs. This study aims to suggest a guideline in designing school sanitary fixture and propose the optimal number of lavatories and drinking fountains regarded to age and sex. The survey is conducted through questionnaires collected from 998 respondents including 300 teachers In ChungNam province. Based on the results of the survey and a formulae, it is suggested that the number of lavatories be required by ratio of 30 boys per unit fixture and 22 girls per unit fixture in the elementary, middle and high school. It is also suggested that the number of drinking fountains be required by ratio of 65 students per unit fixture. The formulae proposed in this paper can be used for other plumbing fixtures required in school facilities.

The purpose of this study was to analyze the patterns and the interrelationships for meeting guidelines of three health behaviors including physical activity(PA), sedentary behavior(SB), and dietary behavior(DB) for Korean adolescents using 2007 KYRBS(Korea Youth Risk Behavior Survey) data. A cross-sectional design was used to assess 73392 middle-high school students. PA(moderate physical activity${\geqq}$5times/week, or vigorous ${\geqq}$3times/week), SB(watching TV, computer, DVD, video, etc. < 3 hr/day), and DB(servings of fruits ${\geqq}$1 times/day, or vegetables ${\geqq}$ 3 times/day) were categorized into two levels (meeting guidelines or not). Chi-squared tests were conducted to compare the prevalence of students not meeting these three health behaviors between boys and girls, and logistic linear regression was used to determine the interrelationships of three health behaviors. Students meeting guidelines for PA, SB, and DB were 31.0%(boys 42.6%, girls 18.0%), 74.7%(boys 75.4%, girls 74.0%), and 38.5%(boys 38.6%, girls 38.4%), respectively. In addition, there were significant differences between both genders for PA and SB (PA; $x^2(1)$=35175.11, p<.0001, SB; $x^2(1)$=19.44, p<.0001). Only 10.9% of students met all three guidelines and 12.4% did not meet all three. Pattern that simultaneously did not meet PA and DB were high in both boys(27.1%) and girls(37.2%). Students who did not meet DB were at greater risk of not meeting PA(Boys; OR 1.49, 95% CI 1.43 to 1.55, Girls; OR 1.42, 95% CI 1.34 to 1.50), and not meeting SB(Boys; OR 1.41, 95% CI 1.34 to 1.48, Girls; OR 1.36, 95% CI 1.29 to 1.43) compared with students who met DB. The findings of this study supported further evidence for the need of a multiple behavior approach considering gender and interrelationships among three behaviors.

Recent research on the fatty acyl chains in the membrane lipids in Sarcina ventriculi has shown that unusually long chain bifunctional fatty acyl components are the major components of the total lipid. However, these studies did not yield any information on the complete structures of the lipid species containing these fatty acids. In this study, the structures of a new family of glucolipids containing bifunctional acyl chains are described. These structures were determined using NMR(Nuclear Magnetic Resonance) Spectroscopy, GC (Gas Chromatography)/MS (Mass Spectrometry), FTIR (Fourier Transform Infrared) spectroscopy, and FAB (Fast Atom Bombardment) mass spectrometric studies. One of the major bifunctional acyl components of the $\alpha$-glucolipids was an $\omega$-formylmethyl ester indicating the presence of plasmalogen. The general structure of the lipid components was one in which the two head groups were separated by a membrane-spanning acyl species. One head group component is a glycerol moiety of each head group, and the other is a glyceryl clucoside. Two regular chain fatty acids, one on the glycerol moiety of each head group, are also present and meet in the middle of the membrane, roughly equidistant from each head group.
