The purposes of this research are to investigate the pollution level of heavy metals due to the urbanization and industrialization in the satellite cities of Seoul, and to assess the chemical species and the sources of heavy metals in highly contaminated soils and dusts. Soil and dust samples were collected from the Uijeongbu and the Koyang cities, which are northern and the northwestern satellite cities of Seoul metropolitan city, respectively. Relatively high pH values($6.3{\sim}9.9$) were found in roadside soils compared with agricultural and forest soils. Difference in pH values of soils was not identified between before and after rainy seasons. In spite of no specific pollution sources in the above cities, the contents of Cu, Pb, and Zn in soils and dusts were much higher than the world average contents. The metal levels in dusts were higher than those in soils, but the metal concentration in dusts was significantly decreased after rainy season. Pollution index was high(> 1.0) in the areas of heavy traffic, industrial complex, and city centres. There is an appreciable proportion of total Zn in exchangeable/water-acid soluble fraction. Copper is predominantly associated with reducible and oxidizable phases, whereas Pb is largely in reducible association. It is concluded that the mobility and bioavailability of metals are high in the order of Zn >> Cu > Pb, on the basis of characteristic particle morphology and chemical composition, Pb-containing particles are originated probably from the automobile exhaust, particularly in heavy traffic areas. The metallic forms and iron-oxide associated forms of Cr, Ni, Cu, Zn, and Pb can be assessed as industrial origin.

Public investment in education has been justified by assumed positive externalities of education. Using the 1995 10% Population and Housing Census and 1998 Korean Labor and Income Panel Study, this study first examines the distribution of human capital across Korean cities and industries, and second, investigates the sizes of external economies of education by exploring how the average schooling of workers in cities and industries affect an individual worker's hourly wage. Generally, the average schooling of workers in the capital region cities is much higher than in other cities and the average schooling of workers in high tech industries is much higher than in other industries. As the average years of schooling in a city increases by one year, workers with the same personal and job characteristics such as sex, education, experience, occupation, and firm size, earn about 3% more. Also as the average years of schooling of workers in an industry increases by one year, the workers with the same personal and job characteristics earns about 5~7% more.

This paper is concerned with analyzing the role of Northeast Asia intercity networks in Northeast Asia in creating regional networks. For the purpose of this paper, we have followed Choe's (1996) definition of Northeast Asia which includes the Russian Fat East, the Northeast region of China, South Korea, North Korea and Japan. The central hypothesis of the paper is that the geopolitical conditions of Northeast Asia compared for example with Southeast Asia, favor bilateral rather than multilateral linkages between nation states. In these circumstances, it is our hypothesis that cities will play an important role in developing a "local image" of regio-nalism and intercity networks. In order to analyze this hypothesis, the paper is divided into three parts. Part A analyzes the emerging urban system of the Northeast Asia region using Choe's concept of the BESETO corridor and updating his data from the late 1980s to the mid 1990s just prior to the financial crisis. This analysis is further supported by the analysis of economic and transportation linkages within the urban system of the region with some discussion of emerging urban nodes. Part B looks at the specific case studies of the region including the Bohai Sea region, the Japan Sea and case studies of Sapporo, the Japan Sea and case studies of Sapporo, Pusan and Shandong province cities. Part C summarizes this preceding analysis and that the development of regionalism and servicing urban nodes is move likely to emerge from a myriad of linkages developed between the region's cities than from a supra-regional role of nation states. This finding has important implications for regional policy formation suggesting that there should be considerate national support for international linkages between cities.en cities.

Waterfront redevelopment is an element in the process of inner-city regeneration now widespread in many ports of the world. Academic interest in the processes involved has yielded a literature biased towards specific locations rather than towards the analysis of processes and issues. The redevelopment of urban waterfronts does not, of course, occur exclusively in port cities but is found as a continuous process in most places where settlement and water are juxtaposed, whether or not commercial port activity is or was present. Port cities, however, as a result of the concentration and juxtaposition of urban and maritime influences, generally present the major issues involved in waterfront redevelopment most clearly. In this context, the general aim is to explore Korean dimensions of waterfront redevelopment in a range of port cities in a context of inner-urban renewal; and a specific objective is to examine the views of decision-makers in Korean port cities on the processes involved by a questionnaire method. The focus is on comparative strategies, and in particular upon the factors affecting the balance between social goals and commercial interests. To test the response of four categories of decision-makers in Korean port cities on a number of issues perceived as underpinning the processes involved in waterfront redevelopment, four catergories of respondents-port authority representatives(PO), urban planners(UP), port specialists(PS) and city-government official(GO)-were asked to fill in a questionnaire form. In three out of ten cases, the overall result broadly confirmed the a priori expectation; in six cases the confirmation was partial; and in one other the view of respondent was generally contrary to those anticipated. In many, but by no means all, cases there was substantial agreement between the four categories of respondents, but the range of scores was generally much wider than expected.

The sound dietary habit is formed in childhood, which is basic foundation for keeping health. The school foodservice is practiced to provide proper nutritions, to establish the sound dietary habit. Continuous evaluation and improvement are necessary to operate school foodservice effectively. This study was conducted to evaluate the quality of meals served in elementary school based on nutrient content, food diversity. A questionnaire was mailed to dietitian of each school requested for menus of one week. Menus served in 77 schools from each province and major cities in Korea were analyzed. The results of this study were summarized as follows; Compared to 1/3 of RDA for children, many schools provide lower amounts of energy, calcium and Vitamin A. Proportions of energy from carbohydrate, protein and fat were 59.64%, 17.43% and 20.11%, respectively and were not significantly different by the area, the foodservice system, and the number of persons served. NAR(nutrient adequacy ratio) were lowest for calcium(0.67) and Vitamin A(0.65). MAR(mean adequacy ratio) was 0.83. The results of comparison of NAR and MAR by the area, the foodservice system, and the number of persons served were similar to those of nutrient contents. Comparing foods served by the nutrient density were different by nutrient contents, NAR and MAR. Mean nutrient density per meal were higher in large cities than in small cities and rural area, in conventional than in commissary foodservice system. Mean number of dishes and food items per meal were 5.86 and 19.87, respectively. The mean of total quantity of each food group per meal was 352g. The mean of total quantity of each food group per meal were higher in small cities and rural area than in large cities, in commissary than in conventional foodservice system. This study is based only on served menus, and the evaluations of meals based on actual consumption of children are needed. These results suggest that in order to improve the quality of school food service, realistic standard should be suggested and basic study should be done continuously.

Purpose: In spite of many Healthy Cities projects in Korea, there are few research about healthy urban planning. So we tried to use available recent models to a Healthy Cities project in a medium sized city in Gyeongnam province. Methods: Using mainly European Healthy Urban Planning Model and opinion leader survey, SWOT analysis, forum and discussion have been done to a city. Secondary city health indicator obtained from Ministry of Statistics. Results: There are strong need to develop health industry, green traffic and healthy living from survey using Healthy Cities policy direction of Korean Health Promotion Fund. Among the Healthy Urban Planning objectives, improvements of physical environments, prevention of accidents and crime, improvements of healthy esthetics rated highly. Although environmental pollution was problem local government push forward to the pilot healthy urban project as active healthy water-front development. Considering secondary healthy city indicators, change of external forces and internal capacity final task for healthy urban planning for Yangsan city were development of riverside physical education park and active living and anti-ageing environments etc. Conclusions: Comprehensive assessment and plan was possible through MAPP Model using European Healthy Urban Planning objectives to draw the direction of future urban planning for Healthy Cities Projects. Further research and formal introduction would be needed.

In a recognition of regional innovation system approach for a co-development effort of the Cheonan-Asan area, Chungnam, this research conducted a survey from the local leaders of these two cities. The results of the survey show that most local leaders strongly agree with the necessity of co-development efforts, that some suggest a merge of two cities, and that some suggest industrial development programs in the city border. The local leaders expect that public officials should play a major role in co-development of the two cities while local leaders are disappointed with the public officials activities. They also highly expect that civilian leaders (NGOs) and professors should play important roles in this matter. Upon these results, the research suggests to formulate a cooperative regional innovation system for the co-development of the two neighboring cities by three steps.

This study was conducted to evaluation the quality of meals served in elementary school based on nutrient contents and food diversity . A questionnaire was mailed to school foodservice dietitians requesting one week menus for April and October . Menus served in 388 schools from each province and from major cities in Korea were analyzed. Mean nutrient contents per meal of persons served, and food expenses per meal. Mean percentages of energy from fat was 20.2% , and was significantly l different by foodservice system. When nutrient contents were converted to amount per 1, 000kcal, all were higher than that calculated from RDA except calcium, iron, and Vitamin A. Most of these were not significantly different according to area, foodservice system, the number of persons served, and food expense per meal. Compared to 1/3 of RDA for children , many meals provided lower amounts of energy, Vit A, VitB2, and Ca. More than half of the meals provided less iron than 1/3 RDA for 10-12 years girls. Using the highest values of RDA for the elementary school age group as evaluation, criteria nutrient adequacy ratios(NAR) were lowest for Ca(0.61), Vit A(0.57), and iron(0.77). The mean adequacy ratio(MAR) was 0.86. Mean numbers of food items and dishes per meal were 15.3 and 5.1 , respectively. 66.3% of the meals provided three food groups of grain, meat, and vegetable. Except for the number of different food items served per meal, the aspect of food diversity was similar to that of nutrient contents. There was significant positive correlation between mean number of different food items served per meal and nutrient content . In summary , schools in small cities and rural areas than those in large cities, schools adapting commissary or joint management than those or density. Also the more food groups served per meal, the higher the nutrient content per meal . In summary , schools in small cities and rural areas than those in large cities, schools adapting commissary or joint management than those adapting conventional foodservice system, schools serving smaller number of persons, and schools with higher food expenses provided higher energy contents and food diversity.

Since the atmospheric clearness index is main factor for evaluating atmosphere circumstance, it is necessary to estimate its characteristics all over the cities in Korea. We have began collecting clearness index data since 1982 at 16 different cities and considerable effort has been made for constructing a standard value from measured data at each city. The new clearness index data will be extensively used by evaluating atmospheric circumstance analysies as well as by solar application system designer or users. From the results, we can conclude that 1) Yearly mean 63% of the atmospheric clearness index was evaluated for clear day all veer 16 cities in Korea. 2) Atmospheric clearness index of spring and summer were 63% and 64% and for fall and winter their values wre 61% and 59% respectively. So, spring and summer were higher, and fall and winter were lower then the yearly value. 3) A significant difference of atomospheric clearness index is observed between $1982{\sim}1987$ and $1988{\sim}1993$ through 16 different cities in Korea.

Estimation of typical solar radiation is very important for the calculations concerning many solar applications. But solar radiation measurements are not easily available because of the expensive measuring equipment and techniques required. Accordingly, for regions where no solar radiation is measured, solar radiation need to be estimated using other meteorological data. However, currently in Korea, there is no study on how to do this. In this paper, the global radiation of the six major cities in South Korea where the global radiation is measured using comparatively simple CRM model was calculated compared and analyzed. The comparison between the original coefficient and the site-fitted coefficient for these cities are as follows. Differences between the site-fitted coefficient and the original coefficient for six cities are small. Except for Gwangju, both calculations show strong correlation. In case of Seoul, the $R^2$(coefficient of determination) were 0.747 and 0.749. In case of Busan and Daegu the figures were 0.817, 0.819 and 0.820, 0.821 respectively. For Gwangju, these were 0.618 and 0.622, Thus, the site-fitted coefficients were slightly higher for these four cities. On the other hand, Daejeon and Incheon was reported 0.773, 0.772 and 0.785, 0.783, respectively.
