Purpose: This study was done to compare health risk behavior prevalence for youth living in metropolitan, medium sized and small cities or rural area, in order to enhance understanding regional differences. Methods: For this study, data from the 2006 Youth Health Risk Behavior Online Survey collected by the Korean Center for Disease Control were analyzed using SPSS. Results: In the metropolitan areas, prevalence for disease and perceived obesity were higher than in other areas. Lack of intense or moderate physical activity, obesity, fast food intake, and insufficient sleep showed higher prevalence than in rural areas. Prevalence of lifetime smoking, lifetime alcohol consumption, present alcohol use, fruit intake less than once a day, and not wearing a seat belt were higher in rural areas than in urban areas. Gender, smoking, and alcohol use were correlated. Spearman correlation between living with parent and skipping breakfast were significant. Smoking, alcohol use, and sexual behavior were correlated. Conclusion: As significant differences in prevalence of youth health risk behaviors exist between regional areas, health education and health promotion programs considering these differences have to be developed and implemented for adolescents. Programs for prevention of smoking and alcohol use, programs for improvement of fruit intake and safety are suggested for adolescents in rural areas, whereas programs to enhance physical activity and obesity management are suggested for adolescents in metropolitan areas.

In this paper, we compared the efficiencies of national R&D investments between NT (Nanotechnology) areas in terms of papers, patents, and commercializations, and found ways to improve the efficiencies of national R&D investments for each NT area. This is in response to huge R&D investments government has made recently in NT areas. Here, we collected data on investments, papers, patents, and commercializations for the R&D projects in NT areas through National Science & Technology Information Service. Based on the data, we analyzed the investment and performances (papers, patents, and commercializations) for each NT area, calculated the efficiency for each NT area, and compared the efficiencies between NT areas. Next, using cluster analysis, we identified several NT areas with similar characteristics in terms of paper efficiency, patent efficiency and commercialization efficiency. Finally, we derived implications for the efficiency enhancement for each grouping. The cluster analysis showed that there could be two groups, one being low in terms of technological outcome (papers and patents) efficiencies and high in terms of commercialization efficiencies, while the other being high in terms of technological outcome (papers and patents) efficiencies and low in terms of commercialization efficiencies. Therefore, the strategy for one group calls for support for technology transfer or technology introduction from other R&D performers and grant of guidance for improving R&D performers' commercialization ability to other R&D performers while the strategy for the other group calls for R&D support for transfer of technology to other R&D performers, activation of technology transfer and support for commercialization of R&D performers.

This study was conducted based on the 115 development projects of residential areas during 2001-2006 to investigate the current status of park green areas. Prior Environmental Review System (PERS) was categorized into regions, scales, and time of the projects, and regression model was used for a statistical analysis. The ratios of greenness of Seoul and Gyunggi province were greater than those of other regions whereas the ratios of greeness of Cheonnam, Chungbuk, and Jeonbuk provinces showed smaller percentage of green areas. Secondly as the scales of development get bigger areas of greenness become larger indicating a large scale residential development projects are favorable for securing green areas. Thirdly the correlation between planned area and green areas, and that between planned population and the ratio of greenness are relatively low (P>0.05). This implies green areas are not a good indicator but a concrete guideline for green areas. Fourthly the ratio of greenness of small scale project is not reached to 10% so that it is recommended to secure over one million $m^2$ areas for development project.

This study proposed a logistics plan for sending supply to be distributed to areas other than producing areas to wholesalers and allocating supply to be distributed to areas near producing areas to local distribution center in the vicinity instead of shipping the entire quantity to wholesalers for fruits auction to increase the competitive edge of the domestic fruits and vegetables logistics market in the ear of infinite competition. A video auction-based short distance division logistics operation model was developed to enhance competitiveness related to the circulation of fruits and vegetables, reduce logistics costs, and rationalize logistics by distributing the items sent to wholesalers through field auction and the shipments at local distribution center to neighboring areas through video auction connected to wholesalers real-time. The study especially came up with a logistics rationalization plan by examining and analyzing the stages and costs of transportation between producing areas and wholesalers on the circulation routes of fruits.

On the basis of morphological and functional studies, it is now established that there exist multiple motor representation areas in the frontal lobe of subhuman primates. Recent development of analysis on cerebral critical organization in human subjects, utilizing novel techniques of PET and MRI, provides evidence of corresponding motor areas. Each area has its unique sources of inputs from the thalamus and from other parts of the cerebral cortex. To understand functional roles of these multiple motor areas, it is necessary to study neural activity while subjects are performing a variety of motor tasks. In view of high accuracy in spatial and temporal resolution, the analysis of single cells in relation to specific aspects of motor behavior remains to be a powerful research technique. It is with this technique that a number of novel concepts on functional roles of multiple motor areas have been proposed.

The Nongkwang variety was sown directly in the field by the three methods of dibbling, drill seeding and broad-casting in non-, low- and high-salty areas, and compared with the growth of transplanted rice in each areas. The yield of rough rice was increased remarkably by direct sowing when compared with that produced by transplanting inboth salty areas, but in non-salty area, the former was decreased significantly. There was no significant difference in the yields of rough rice resulting from three seedling methods of direct sowing in each area. The direct sowing method was predominated in number of panicle, weight of panicle, ratio of matured grains, milling recovery percentage, and straw weight in both salty areas, and dicreased in panicle weight and ratio of matured grain in nonsalty area.

The medical insurance system has been adopted in rural areas in 1988. Since then, the utilization of medical care services has increased rapidly in rural areas. According to the various study on medical care utilization, the people in rural areas used more curative care services than urban areas. The purpose of this study was to analyze the utilization and expenses of medical care services in designated rural areas : Choonseong Gun, Kangwon Province ; and Soonchang Gun, Cheonbuk province in Korea. Medical care utilization of medical care beneficiaries showed slightly increase, while there was a decrease of 18% and more for the medicaid. Regarding selection of medical care institutions, medical care beneficiaries used more hospitals and clinics than health center networks, but the health center networks was used more by the medicaid. However, the hospitalized Soonchang health center was able to provide more curative care to the people than the other two health centers. More than 50% of the patients treated by hospitalized health center were residents of the place in which health center was located.

The purpose of this research is to conduct an empirical analysis regarding Korea's 'Marine Protected Areas (MPA)' from an international comparative perspective. The authors would like to present the policy direction of marine protected areas based on the result of the research. The result of this study can be summarized in the following manner: First, the total designated size of marine protected areas in Korea is very small compared to the sizes of other OECD nations . Second, while some nations have expanded the extent of marine protected areas in accordance with international agreements and criteria, Korea has not done so. Accordingly, we propose the designated dimensions of marine protected areas should be constantly expanded to keep pace with international trends.
