  • In modern society, diverse vulnerable population, such as homeless, disabled, elderly and so on, have been prominently appeared with polarization of wealth because of radial biased economic development and urban sprawl. Housing acquisition is a difficult problem for the venerable population to get, so appropriate alternatives should be explored. In USA, under the 'Housing First' principle, supportive housing has been developed as a main alternative. Sharing this alternative experience is very valuable to promote future development including policies. The purpose of this study is to delineate the trend of supportive housing research. This research is conducted by content analysis technique, and data were recent 29 research articles dealing supportive housing, collected from medical service data base where supportive housing research has started and diffused. As results, overall trends and characteristics appeared that the main research field was Psychiatry/Psychology, and mostly, they were correlational research. Mainly, resident type was mentally ill, and the principal research method was secondary data analysis. In general, all the service programs were mostly essential, and the number of congregate housing type appeared dominantly. The modern supportive housing is a social intervention to cope with instability of future housing welfare.

  • An oil-filled paper-insulated power cable and a XLPE-insulated power cable have been mainly applied as an extra-high-voltage underground power cable. But in recent the XLPE cable has been applied more widely than the OF cable, because of its advantages, such as the low-cost and simple installation. In general two types, molded and prefabricated, of straight joints are applied for the XLPE cables. For a tape-molded joint, one of molded joints, its electrical properties are excellent, but it has some disadvantages, such as a long working time. high skill of workers and the high cost of jointing equipments. For a prefabricated joint, developed and applied in Europe and Japan, its working time is short, its jointing procedures are simple, and its quality control is easy, but its prices are very high. In Korea the development of a compression-type PJ will be finished in the near future, and studies of its jointing techniques and equipments is actively going on. This paper describes the design and construction of the PJ, the jointing procedures and techniques for the PJ, and its future trends.

  • Satellite-based land surface temperature (LST) has been used as one of the major parameters in various climate and environmental models. Especially, Moderate Resolution Imaging Spectroradiometer (MODIS) LST is the most widely used satellite-based LST product due to its spatiotemporal coverage (1 km spatial and sub-daily temporal resolutions) and longevity (> 20 years). However, there is an increasing demand for LST products with finer spatial resolution (e.g., 10-250 m) over regions such as urban areas. Therefore, various methods have been proposed to produce high-resolution MODIS-like LST less than 250 m (e.g., 100 m). The purpose of this review is to provide a comprehensive overview of recent research trends and challenges for the downscaling of MODIS LST. Based on the recent literature survey for the past decade, the downscaling techniques classified into three groups-kernel-driven, fusion-based, and the combination of kernel-driven and fusion-based methods-were reviewed with their pros and cons. Then, five open issues and challenges were discussed: uncertainty in LST retrievals, low thermal contrast, the nonlinearity of LST temporal change, cloud contamination, and model generalization. Future research directions of LST downscaling were finally provided.

  • This study reviews and compares the selection procedures for science and technology topics to predict mid- and long-term trends in science and technology development in Korea, Japan, and the United Kingdom. It then identifies science and technology topics and future technologies for the third science and technology foresight of Korea. In Japan and the United Kingdom, non-technological topics that reflect socioeconomic needs are also select-ed along with technological ones. This study provides the following policy implications to enhance reliability and effectiveness of the third science and technology foresight of Korea. First, selection of science and technology topics should coincide with the national goal, taking into account development trends in science and technology and socioeconomic needs. Second, the current prediction methodologies such as "delphi" do not fully consider future uncertainties in science and technology development. A scenario method is, for example, needed to present coherent pictures of alternative futures. finally, the third technology foresight should select and include topics that reflect domestic conditions and global trend in technological progress. This study suggests 117 topics for the third science and technology foresight.foresight.

  • Korea's marine products trade is taking for phase that income exceeds export after 2000. According to external environment change of Korea and Japan fishery agreement and an import liberalization of marine products, import of live fish and fresh fish is increasing rapidly. This study investigates import view of Japan live fish and fresh fish. Live fish which is imported from Japan has red seabream and seabass, but it is in declining tendency because of the increase in import of cheaper croaker from the China. If see importer's trend, entry to import business of fresh fish is eased a little. If a circulation trend is seen, However, it is thought that a future import trend is influenced by economic trends of Japan and the grade of place-of-production development of a domestic trader. Circulation market outside is common and the district wholesale store has played the important role. The import view of Japanese live fish and a fresh fish will increase against the background of maintenance of domestic circulation organization, and upgrading of marine product consumption However, it is thought that a future import trend is influenced by economic trends of Japan and the grade of place-of-production development of a domestic trader.
