The purpose of this study is to analyze how the commuting areas in the Busan metropolitan area have been changed during 2000~2010. For this purpose, I set the boundary of the Busan metropolitan area by using linkage indicators, and analyzed the changes of the commuting areas by using factor analysis. The commuting areas in the area were divided into four subregions, including East Busan, West Busan, Gimhae/Changwon, and Ulsan. The commuting area of West Busan has been shrinking, and the commuting network structure between Gangseo-gu/Buk-gu/Sasang-gu and their geographically adjacent Gimhae/Changwon has been gradually strengthened. This has resulted from the increase of reverse commuting from West Busan to Gimhae/Changwon. Ulsan has formed an independent commuting area in the area.

We analyzed the recent characteristics of Particulate Matter (PM) including PM₁₀ (PM with diameter of less than 10 ㎛) and PM_2.5 (PM with diameter of less than 2.5 ㎛) observed in Busan metropolitan area, and compared them with those measured in Seoul metropolitan area. This analysis includes the monthly, seasonal, and annual variations and differences, in emissions and chemical compositions observed in both Busan and Seoul areas. Synoptic meteorological conditions were investigated at the time when high PM concentrations occurred in each of the two areas. The results showed clearly decreasing trends of annual mean concentrations with strong seasonal variations: lower in summer and higher in winter in both areas. In comparison with Seoul, the seasonal variation in Busan demonstrated relatively lower, but showed greater summer fluctuations than in Seoul metropolitan area. This is implying the importance of secondary generation of PM in summer via active photochemical reaction in Busan area. In high concentration days, Busan's chemical composition of sulfate was higher than that of nitrate in summer, whereas nitrate was higher than sulfate in Seoul. The ratios of NO₃^- to SO₄^2-(N/S ratio) showed lower in Busan approximately by a factor of 1/2(half of N/S ratio) in Busan compared with that in Seoul. Others such as synoptic characteristics and emission differences were also discussed in this study.

We have investigated coarse wind sectors in Busan metropolitan area and simulated detailed wind field using local atmospheric circulation model, RAMS in preceding studies (Part I, Part II). In this study, we divided and analyzed local wind sector in Busan according to the preceding results. We found that Busan metropolitan area is divided into 2 or 3 local wind sector in each coarse wind sector. The 9 coarse wind sectors were classified into 20 local wind sectors in total. But three local wind sectors were finally excluded because of these sectors were located on the complex hill area and the sea. Local wind sectors, therefore, in Busan metropolitan area were defined as 17 regimes. We assessed the location of air qualify monitoring sites at Busan metropolitan area using the information of these wind sectors. Most of these were located at proper points, but 6 sites were placed at 3 local wind sectors as a couple and no site was set up at 3 other sectors. Hence the location of these sites was in need of rearrange.

This study intends to demonstrate that the population decrease in the City of Busan has been resulted from the move of the city's population towards suburbs as well as the out-migration towards the Seoul metropolitan area. To grasp the pattern in the spatial shift of the Busan's population, I analyze the change of population and households within the city and the migration at the inter-regional and intra-metropolitan scales. The major findings of the study are as follows: First, Busan has experienced population decline since 1995, as other large cities, such as Seoul and Daegu have done. Second, despite the population decrease, the number of households has been increased in Busan. Third, the residents of Busan have mostly moved not only to the Seoul metropolitan area but also to the suburban region of Busan. This finding may well contradict the long-standing belief that the continued decrease in the Busan population could be the result of the out-migration toward the Seoul metropolitan area. Fourth, the residential suburbanization in Busan can be interpreted as the extensive intra-metropolitan dispersion, which means the growth of the Busan metropolitan area.

This study is to propose guidelines on waterfront landscape planning for Busan North Port redevelopment area. In Korea, Busan North Port redevelopment project is the first one which aims to make old port area into citizen-friendly waterfront. It is expected that many ports will be redeveloped soon after this urban waterfront remaking project. This is the basic research to lay groundwork for waterfront landscape planning at port redevelopment area. We analyze good examples of genera/landscape plans for port redevelopment area through case studies and suggest the problems and important elements for making landscape plan of Busan North Port area. Also we propose guidelines for making waterfront landscape plan of the redevelopment area at Busan North Port.

This study is to propose key directions of Busan North Port redevelopment for revitalization of waterfront. Since 1960s, there have been a lot of port redevelopment projects around the world. In Korea, Busan North Port redevelopment project is the first one which aims to make waterfront citizen-friendly within old port area. Many ports will be redeveloped soon after the Busan North Port redevelopment. At this time this is the basic research to lay groundwork for the systematic and efficient port redevelopment. We analyze the good examples of the world through case studies and suggest the problems and important elements of success of port redevelopment. Also we propose the objectives for waterfront revitalization and the visages of waterfront within port area. And then we analyze the situation of Busan North Port and examine the blueprints issued by national and city government. After that we suggest some ideas, such as land use plan, on North Port redevelopment for revitalization of waterfront in Busan Port Area.

Purpose : The purpose of this study is to look into the change of area and space organization percentage of wards in main general hospitals in Busan and Gyeongnam. Method : Patient area, nursing area, service area, training area, common area were classified for functional space organization. Patient area was reclassified to bedroom and comfort area, and common area was reclassified into vertical circulation, horizontal circulation and facility area. Also, method of area calculation was chosen standard to wall center-lines following building act 911 and functional space area of each hospital was estimated and comparatively analyzed. Result : For hospitals completed before 2000, area ratio by functional space for patient area, nursing area, service area and common area showed 53.6%, 10.2%, 0.8%, and 35.3% respectively. For hospitals completed after 2000, area ratio by functional space for patient area, nursing area, service space, and common area showed 49.2%, 12.6%, 1.1%, and 37.2% respectively. Implications : Through this study, change of percentage of space organization of main general hospitals in Busan Gyeongnam can be understood. Also because most studies on area organization of general hospital wards were focused on the capital area, this study provides basic material for future studies related to area of general hospital wards in Busan Gyeongnam.

The purpose of this paper is to introduce the new way of location choice for free trade zone in Busan area by using Obata and Ishii(2003) model of preference discrimination score. And also, this paper investigates the result of Choi, Bong-ho(200l) that deals with the choice of tariff free area in Busan area. Empirical main results are as follows: First, the North Port(Sinsundae)and the New Busan Port are efficient. Final winer of location choice for free trade zone is the North Port(Sinsundae). Second, the ranking result of this paper for 10 potential sites of free trade zone shows the almost similar to that of Choi, Bong-ho(200l). Policy planner for location choice of free trade zone should introduce the preference discrimination score method by Obata and Ishii(2003), because this method shows the very positive empirical results like questionaire method by expert groups and common people in Busan which should cause the much time and much money.

This article is focused on the agglomeration and decline factors of the footwear industries in Busan metropolitan area from the industrial cluster point of perspective. For the research, 'the components and network of industrial cluster model' are presented which is restructured of M. Porter's cluster model. Moreover, this research have examined the agglomeration and decline process of the footwear industries in Busan area and conducted a survey targeting footwear enterprises in Busan area. In the late 1980's, the footwear industries in Busan area formed the largest footwear industrial cluster in the world. However, the industrial cluster started to decline from early 1990's and now it is reduced in to 1/10 size of the past. The growth factors of Busan footwear industrial cluster include cheap and plentiful labours, penetration of OEM production, entrepreneur spirit, human resources network, government's support and so on. Moreover, the agglomeration of relative companies also created high competitiveness in this cluster. The decay factors are pointed out sudden rise of labour cost, shortage of factory site, rise of land price, alteration of government policy, international relocation of footwear production and growth of overseas industrial cluster. Busan footwear industrial cluster nowadays has declined in its size, but it is the only footwear industrial cluster in Korea.

Ozone is the secondary photochemical pollutant formed from ozone precursor such as nitrogen dioxide and non-methane volatile organic compounds(VOCs). The ambient concentration of ozone depends on several factors: sunshine intensity, atmospheric convection, the height of the thermal inversion layer, concentrations of nitrogen oxides and VOCs. Busan is located in the southeast coastal area of Korea so the ozone concentration of Busan is mainly affected from the meteorological variables related to the sea such as sea breeze. In this study the ozone concentrations of Busan in 2008~2010 were used to analyse the cause of the regional ozone difference in eastern area of Busan. The average ozone concentration of Youngsuri was highest in Busan however the average ozone concentration of Gijang was equal to the average ozone concentration of Busan in 2008~2010. The two sites are located in eastern area of Busan but the distance of two sites is only 9km. To find the reason for the difference of ozone concentration between Youngsuri and Gijang, the meteorological variables in two sites were analyzed. For the analysis of meteorological variables the atmospheric numerical model WRF(Weather Research and Forecasting) was used at the day of the maximum and minimum difference in the ozone concentration at the two sites. As a result of analysis, when the boundary layer height was lower and the sea breeze was weaker in Youngsuri, the ozone concentration of Youngsuri was high. Furthermore when the sea breeze blew from the south in the eastern area of Busan, the sea breeze at Youngsuri turned into the southeast and the intensity of sea breeze was weaker because of the mountain in the southern region of Youngsuri. In that case, the difference of ozone concentration between Youngsuri and Gijang was considerable.
