When the castle of the city was destructed from 1911 through 1915 in Cheongju, the city's spatial structure was reorganized and "Han-ok Housing", a dwelling site filled with Korean traditional houses, was newly formed around the former castle site. These days, the Han-ok housing in Seoun-dong, Cheongju in which elderly couples and senior citizens live is enclosed by modernized roads and three or four-story buildings, leaving the housing as an isolated island in the city block. Nonetheless, the Han-ok housing not only plays an important role in sustaining the historic and local identity of the city, but also offers environmental benefits in terms of daylighting and ventilation. The purpose of this study is to reorganize the housing suitable for those who currently live and recreate it by adding new functionality. Consequently, three strategies are established; the conservation of existing building through the improvement of existing facilities; the conversion of vacant buildings into a new use; and the creation of the urban mid-rise Han-ok housing at street sides. The first strategy has a significance in that the traditional building's single wing plan, small room sizes and lack of storages now cause great inconvenience for current life style. The second strategy also promotes the practical use of abandoned buildings through alterations and additions. Finally, the creation of the urban mid-rise Han-ok housing that is accomplished by the combination of reinforced concrete and wooden structure interacts with or respond to the city's development. As a result, this study for the adaptive reuse of Han-ok housing proves how the traditional properties can be maintained in a careful manner and how its creative reuse can be achieved.

This paper is to evaluate an open space on university campuses enclosed within buildings, with respect to building elevation a wall of an open space including outer wall materials and window forms and an open space itself. It uses case study methods to periodically know specific details about open spaces and surrounding buildings elevation. It was found, at first, that it was emphasized vertical elements on window frames as well as building elements in an era of the 1910's to the 1930's. It, however, was changed into emphasizing on horizontal features in the era of the 1960's to the 1970's. Meanwhile the period from the 1940's to the 1950's was a turning point. The horizontal style was continued until the 1980s and the style was changed into various style mixed with various types. Secondly, an open space was recognized as a valuable design criteria for a construction of buildings in the 1930s to the 1970s. It was, however, a forgotten criteria during the late 1970's and the 1980's because of short age of the construction budget of the government. In the 1990's, the importance of open space design reappeared on the design of a block plan. Thirdly, a design style of an open space was authoritarianism using symmetrical and magnificent style in the 1910's to the 1930's. The time of 1945 to the 1950's was a turning point from authoritarianism to an idea of efficiency. In the 1960's and the 1970s, an idea of efficiency emphasizing their functions was prevalent to the design of buildings and open spaces and this trend was continued until the 1980's. A romanticism was realized on the design of an open space and surrounded building's.

In this paper, because of global environmental problems such as energy shortage and abnormal climate, green energy development and energy saving technology development is being magnified. Heat insulation, the most basic and traditional energy saving method, is highly expected. Especially, simple and advanced heat insulation technique based on Nano material is promising future technology. The railway system also requires heat insulation. Especially, traditional heat insulator such as glass wool has been adopted frequently to rolling stock. The heat insulator is also adopted in general railway service buildings. Take account of cost-effective heat blocking performance, the heat insulator shall be adopted in diverse fields such as electric power, railroad, signal and communication. The only and direct solution for this problem is installing heat insulator with outstanding endurance, corrosion resistance and heat resistance to block outer heat Upgrading heat specification of equipment can be a solution, but since price and maintenance cost rise severely, this plan might be incongruous. In this research, energy saving effect of ultrathin heat insulator film was demonstrated by installing the film on roof of electrical room.

This study intends to review the development of Squid Angling Fisheries of Korea and Japan and subsequent changes in the fisheries regime as well as management conditions and to examine reorganization directions. Although catches and productivity are all increasing in Korea and Japan as the squid resource in the East Sea is improving, the number of fishing vessels and the conditions of fisheries management are showing a symmetrical relationship. The former is increasing in Korea and decreasing in Japan while the latter is aggravating in Korea and rather stable in Japan. And while the competition between the two countries for more fishing grounds and catches are not that serious since the resource is relatively increasing, the catch and price competition with other domestic fisheries is a more significant problem. Furthermore, even though light restriction is implemented in both countries in order to suppress over-competition, it is adopted as a means to curtail management costs and block over-investment rather than to adjust international or inter-fisheries circumstances. Japan has been implementing the TAC system on squid resources since 1998. However, it has a different meaning than as a resource management method in its original sense because it is based on the highest catch level of the past and takes into consideration the fishermen's management conditions. In case of Korea, it is necessary to establish a plan to strengthen its fisheries management competence to address its shrinking catch in the Japanese waters. The developments mentioned so far have appeared amidst the increase of squid resources, and if such conditions disappear, problems such as international allocation of catches and fishing seasons, access to fishing grounds, and domestic conflicts among different fisheries will emerge.

The road traffic noise has been increasing broader effects on urban areas as well as rural areas because of rapidly increasing traffic volume and newly-constructed roads. 10 sites in building development areas were selected and the noise levels were measured by the apartment floors and by the various block plans of apartment complex. The results showed that the highest traffic noise level was obtained at the 5 and 7 floors on the apartment floors. On the basis of 7 floor with the highest level, the correction coefficient obtained from noise reduction by each floor and measurement point was -5.54 dB(A)(1st floors), -0.96 dB(A)(3rd floors), -0.38 dB(A)(5th floors), 0.00 dB(A)(7th floors), -1.98 dB(A)(l0th floors), -3.10 dB(A)(13th floors), -3.45 dB(A)(15th floors). The level of road traffic noise in the arrangement construction of right angle was about 3.0 dB(A) at N-4 point and 2.1 dB(A) at N-6 point lower than that of a plan figure, respectively. The results suggested that application of correction coefficient obtained by the apartment floor and by the arrangement construction can be improved in road traffic noise.

1년 전까지만 해도 조선시황은 한없는 호항을 누릴 것으로 보였다. 그러나 2008년 후반에 찾아든 글로벌 경제의 불황은 바로 해운시장을 뒤흔들었고 그 여파는 바로 조선 사장에도 한없는 추락을 가져오고 있다. 저자들은 이러한 사태를 예견하여 이미 드라이 도크의 건조에 신중을 기할 것을 주장한 바 있다. 여기에 비하여 Floating Dock는 건조 비용도 덜 들고, 건조 기간도 짧고, 이동성마저 갖추고 있기 때문에 훨씬 더 유연한 도크 건설 방법이 될 수 있다. 그러나 Floating Dock는 대형의 블록을 탑재할 때 갑작스런 중량의 이동으로 인한 중심의 큰 변화로 안정성이 크게 위협 받게 된다. 따라서 안전하게 블록을 탑재하기 위하여서는 아주 고도의 정밀한 발라스트 작업이 수행되어야 한다. 본 연구에서는 육상에서 만들어진 거대 블록을 플로팅도크에 밀어 넣는 Skid Launching System을 위한 플로팅도크 제어 시스템을 완성하여 안정적인 SLS를 구현하고자 한다. 이를 위하여 저자들은 우선 가상의 진수 절차를 만들어 모의 조정하는 시뮬레이터를 개발(Kim et al. 2008)한 바 있다. 본 논문에서는 이시뮬레이션을 바탕으로 실시간 모니터링하면서 실시간 제어하는 시스템을 만들고 실제 진수에 적용하고자 한다.

This paper tried to find out the various symbolic meanings and functions of landscape elements which Capital City of Shilla Dynasty contains, and what is the symbolism and identity of the city. Basically, this research took the thought of the place and the theory of cognition on landscape as a research tool, and undertook the process of surveying the physical surroundings of the city such as mountains, forests, tumuluses, mountain fortress walls, etc. Especially, the study referenced to a myth, thought, and a tale related to them of the surroundings. The research scope in time had been reached to the year of BC 57 which is beginning year of Shilla Dynasty form AC 467 which is year of introduction of new urban block system delivered from Dang Dynasty of ancient China. The results of research showed symbolic meanings of mountains and forests which is surrounding the Shilla capital from 4 directions of east, west, south and north. Namely, it was the places that the king of the kingdom of Shilla decent into the earth from the heaven. Also, the tumuluses which are located on the center of the capital imitated the surrounding mountains in forms, meaned the place that the dead king rised to heaven. All of these symbolized the Capital City of Dynasty as a sacred city which linked the heaven to earth, and earth to heaven. Finally, this paper suggested the Kyongju which is one of the most representative historic and tourist city in Korea should reflect this kind of symbolic meaning of ancient Capital City of Shilla Dynasty in case of arranging the urban identity plan to promote the quality of urban environment of Kyongju.
