The land and sea breeze over the Pusan coastal area is studied by three dimensional mesoscale numerical model. According to the results of the simulation experiments, both Pusan areas and Kimhae areas, the sea breeze began at 0800LST and the strongest at 1500LST and then at 1800LST. After midnight, the sea breeze changed about the land breeze and become weaker than that of the sea breeze in the daytime. Comparisons between calculations and observations showed that the characteristics of diurnal variation and v-component of the wind velocity relatively is similar to the Pusan areas. On the Kimhae areas, however, observations showed time lag which compared to the results of simulation experiments in the velocity of sea breeze and diurnal variation. From the above results, comparisons between calculations and observations is much more similar to the coastal areas than on the inland area.

Most of Cities are suffering from the traffic congestion problem with the vehicles increased. Especially, the City of Pusan is experiencing the severest traffic congestion with the lower read capacity and the higher travel demand than any other cities in the country. Thus, the purpose of this study was to grasp the conditions, review the problems and finally suggest the improvements which we faced at this time for the construction of the Urban Transportation System considered in Pusan area. Based upon the results, it was concluded that firstly the Urban Transportation System(UTS) in Pusan area should be constructed by the Public Transportation System in the center of the Public Transit Modes(i.e., bus and subway), secondly the Para-transit Modes(i.e., Light Rail Transit, LRT) introduced, and thirdly the Transportation Demand Management(TDM) implemented with the expansion of the transportation facilities if possible.

In this study a survey was conducted to compare the foods prepared for the Korean ancestral service on Memorial Day, Thanksgiving Day and New Year's Day in the Yeosu and Pusan areas. Me(tap) as the main food in the rituals was highly used on New Year's Day in the Pusan region, whereas Tteokguk was highly used in the Yeosu region. As for soup ingredients in the rituals, jogae, soegogi and mu were more frequently used in the Pusan region than in the Yeosu region on Memorial Day and festive days. Jogijjim, gaorijjim, sangeojjim, myeongtaejjim, galbijjim, dakjjim, and bugeojjim were highly used in the Yeosu region but cheongeojjim and domijjim were highly used in the Pusan region. Gosari and doraji namul were highly used in both regions but most vegetables were hishly used in the fきn region except for sukju and chwi namul. Jogi gui was the most common in both regions, whereas seodae, yangtae and byeongeo-gui were highly used in the Yeosu region but dubu, jogi and mineo-gui were highly used in the Pusan region. Songpyeon injeolmi, gangjeong, and yakgwa were highly used in the Pusan region. Most fruits except apple were highly used in the Pusan region. With regard to the liquor used for the rituals, there was no difference in the use of cheongju between the two areas, whereas takju was highly used in the Pusan region but soju was highly used in the Yeosu region. The results of this study showed that the use of ritual foods varied a little according to the region and that ritual food use was based on seasonal foods, preference of ancestors, and special products of the region.

A new type ac plasma display panels(PDPs) cells are designed and tested electrically and optically. One cells have the structure of sin discharge path shape and small electrode area. The other cells have the non-symmetric structure with a same electrode area. They show a higher luminous efficienccy and a lower power consumption about 30% improvement than the conventional standard ac PDP cells.

In according to the rapid economic growth and strengthening of economic cooperation of Asian-Pacific countries, Pusan is capable of developing to the international trade center of Pan-Pacific Area. Therefore a lot of functional preparations are required for the international trade center. First the expansion and functional specialization of harbor which is a gateway of international physical distribution is required. Second, raising physical distribution inducement effect through establishment of free trade zone and producing financial and information service accompanied with trade activity through establishment of international financial center and teleport are necessary. And the research complex of high technology (sciencepark) which utilizes the industrial base of Pusan area is necessary for the development of Pusan toward the international trade city. And the establishment of marine sightseeing complex in Pusan utilizing the ocean natural resource is helpful for the growth of Pusan to the international trade center.

부산항 해역의 지표성 요각류의 분포 및 11∼22개의 분류군에 속하는 동물플랑크 톤 군집을 다양도 및 집괴분석으로 분석하였으며 이들 생물학적 결과를 수온, 염분, COD, TIN의 분포와 연관시켜 부산항 해역의 해양환경을 고찰하였다. 네 무리의 요각류 들이 출현하였으며, 이들은 난류성 외양종무리인 Acrocalanus gacilis, Euchaeta plana, pareuchaeta russell and Pleuromamma gracilis 연안성 저온종인 Centropages abdominalis, 한류성 종인 Metridia lucens, 오염지표종인 Acartia omorii였다. 부산 항 외항의 경우, 10월에는 난류 외양성 종들이, 1월과 4월에는 연안 저온성종들이 우 세하였다. 내항으로 접근할수록 오염지표종인 Acartia omorii의 분포가 우세하였으며 COD 및 TIN의 분포 또한, 외항에서 내항으로 가면서 높아지는 경향을 나타내었다. 반 면에 다양도는 외항에서 내항으로 가면서 낮아지는 경향을 나타내었다. 집괴분석에서 10월과 7월에는 3개의 해역으로 그리고 1월과 4월에는 2개의 해역으로 나뉘어졌다. 해 역 I로 대벌되어진 부산 외항 해역은 외양수의 영향을 받는 해역으로 다양도가 높으 며, A. omorii의 밀도가 낮고 요각류의 조성률이 높게 나타났다. 외항에서 내항으로 가면서 대별되어 진 해역 II와 III은 해역 II에서 III으로 가면서 점차적으로 다양도 가 낮아지며, A. omorii의 밀도는 높아지는 특성을 나타내었다. 또한, 요각류의 조성 률이 낮아지며, 4월에는 해역 II에서 원생동물인 Noctiluca scintillans가 최우점군이 였다. 그리고 7월에 해역 III에서는 지각류가 취우점군이였다. 지표성 종들의 분포와 집괴분석에서 나뉘어진 해역은 해양 환경과 밀접한 관계를 나타내었다.

A lot of researches about dye-sensitized solar cell (DSC) are recently being conducted. Because DSC has several advantages to pass the limits of silicon solar cells such as a low manufacturing expense, a simple manufacturing process and its transparency. But most researches on DSC are still conducted about the unit cell and laboratory-centered. That is, present researches on DSC are not practical. Therefore, researches about large area cells and modules have to be prerequisites for DSC to have the practicality. Characteristics of large area DSC are so different from those of small area DSC in aspect of fill factor and efficiency. In this study, we made an experiment on finding suitable size of DSC that has the most effective power according to the variation of active area. In detail, the experiment was conducted about the optimum ratio of length to width and we introduced the ratio of active area to non-active area to find the active area which has the best output. Because small DSC doesn‘t have the best output in comparison with total area of cell although the smaller DSC has the better efficiency. As a result, we achieved the optimum ratio of length to width of 8:3 and active area of $8cm^2$ as the optimum size for upscaling DSC.

In this study, we researched the energy load according to the change of the inner window area ratio, the distance of the air gap and the azimuth of the curtain wall building, which installed the multistory double-skin facade(DSF). and we compared the results with the no double-skin facade situation as follows. With the DSF, it is better than other case, when the window area ratio is 40% and the air gap is 1.2m on the west, south-45-west, south-45-east and east. And it's best when the window area ratio is 40% and the air gap is 0.4m on the south. And on the east or south-45-east, the window area ratio is 40% and the air gap is 1.2m is better than other case with the DSF. On south, it is best when the window area ratio is 100% without DSF. On the south-45-west or west, it is best when the window area ratio is 40% without the DSF.
