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.

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.

The relationship of zooplankton communities and distributions of copepods as indicator species to environmental variables, such as temperature, salinity, chemical oxygen demand (COD) and total inorganic nitrogen (TIN) was studied in Pusan Harbor in October 1990 and January, April and July 1991. Zooplankton communities were analysed by using cluster analysis and species diversity index. Four groups of copepods as indicator species were Acrocalanus gacilis, Euchaeta plana, pareuchaeta russell and Pleuromamma gracilis as the oceanic warm water species; Cemtropages abdominalis as the neritic cold water species; Meridian lucens as the oceanic cold water species Acartia omorii as the polluted water species. the offshore waters of Pusan harbor was dominated by the oceanic warm water species in October and by the neritic cold water species in January and April. This area showed the low values of COD and Tin. the inshore waters of Pusan harbor, where the high values of cod And Tin and the low value of diversity were recorder was represented by A.. omorii. Cluster analysis of the zooplankton community revealed two or three regional areas in Pusan harbor. Area I, the offshore area of Pusan harbor, not only was represented high species diversity and low density of A. omorii but also was dominated copepods in zooplankton roups. Areas II and III were grouped horizontally from offshore to inshore of Pusan harbor. Area II was showed intermediate values in diversity, density of A. omorii and percentage composition of copepods. Area III was revealed the lowest diversity,density of A.omorii and percentage composition of Cladocerans.Coperpoda was a dominant zooplankton group in each area during the study periods except two special cases.Area II was dominated by Noctiluca scintillans in April and Area III was occupied by Cladocerans in July.Distribution of Indicator species and areas demarcated based on cluster analysis showed a close relationship with environments.

Background: This study investigated the risk perceptions, prevalence of environmental diseases (EDs) and associated factors with the prevalence of environmental disease among the population living near an incinerator Methods: Study area were divided into 3 local areas near the incinerator by distance (A, B, C) and control area (D) by distance and geographic isolation. A Questionnaire was conducted with 1,380 in local residents (A, B, C) and 390 in control area (D), gathered information of demographic characteristics, lifestyle, perception of damage by incinerators, experience of EDs (atopic dermatitis, allergic rhinitis, asthma) diagnosed by physician. Analysis of variance, χ² test, and Kruskal Wallis test was applied to determine the difference by area. Logistic regression analysis was performed to identify factors associated with the prevalence of allergic rhinitis. Results: Residents residing closer to the incinerator had negative perception in most items in questionnaire compared with control. The prevalence of allergic rhinitis was higher as they lived nearby the incinerator (p = 0.008). The associated factors with the prevalence of allergic rhinitis were carpet (odds ratio [OR]: 1.79, p = 0.001), residential area (marginally significant), duration of residence (OR: 1.09, p < 0.001). The perception of environmental pollution around the residential area was inversely associated with the prevalence of allergic rhinitis: perceived as very dissatisfied (OR: 4.21, p = 0.02) compared with very satisfied. Conclusions: As closer to the incinerator, the risk perception tend to negative and prevalence of EDs were increased. Carpet, residential area, duration of residence and perception of environmental air pollution around the residential area were associated with prevalence of allergic rhinitis. These results may be useful for the communication with residents to discuss the environmental problems caused by the incinerator.
