This paper studies the long-run behavior of relative price dispersion among cities in Korea with a special emphasis on heterogeneous transitional patterns of price level dynamics. Formal statistical tests indicate considerable evidence for rejecting the null of relative price level convergence among the majority of cities over the sample period of 1985-2015. The analysis of gravity model suggests that the effect of transportation costs on intercity price level differentials is limited, while other socioeconomic factors, such as income, input factor prices, demographic structure, and housing price growth, play key roles in accounting for persistent regional price level disparities. Individual price levels are found to be better explained by a multiple-component model, and the deviations from PPP may be attributed to distinct stochastic common trends that are characterized by income and demographic structure.

There is both a commercial and social imperative for innovation-led economic development. The data on inventions shows the importance of cities in the role of creating this important foundation to innovation. The importance of new venture firms in the innovation process of taking inventions to market is widely recognised, and with this recognition the science parks and science cities are working to understand and replicate the social, business and technology environments which are most fertile for these companies. This paper reviews how those with an interest in this process have addressed this challenge with new business practices and planning activities. It draws particularly on the experiences of Tech City in London and the Surrey Research Park

A survey of radon concentrations in both indoor and outdoor atmospheres was carried out using EIRM and Cup Monitor for the period of February 1996 to March 1997. EIRM were used to measure the indoor and outdoor radon concentration at five major cities university. Cup Monitor were also used to measure the indoor radon concentrations at shopping store, office building, apartment, hospital and house in Seoul. The mean indoor and outdoor radon concentrations at the five major cities(Seoul, Daegu, Daejon, Cwangiu and Busan) were 24.1 Bq/m$^3$and 8.62 Bq/m$^3$, respectively. The ratio of indoor to outdoor radon concentrations ranged front 1.7 to 3.9. Inspection of its seasonal distribute pattern indicates the enhancement during winter relative to summer, consistently for both indoor and outdoor air. The results of the survey showed that the concentrations in basements were clearly higher than those in usual living/working places.

The research deals with the establishment of transportation areas in the metropolitan cities. The purpose is three-fold ; 1) to review the existing literature : 2) to analyze the commuting (work and school) pattern and interregional movement pattern of passengers and freights ; 3) to establish the metropolitan transportation area based on the above analyses. The transportation area is defined by the analysis of trip pattern to the center city of each metropolitan area. The detailed indices for establishment are selected by the rank-size and time-distance analyses. For the operational purpose, the study defines 3 different transportation areas as follows : the first transportation area means the directly effecting region of the center city ; the second means the region with many reverse trips and development potentials ; and the third means the indirectly effecting region. It can be concluded that the first transportation area includes 10 cities and 5 counties in Seoul metropol tan region, Yangdsan-Gun, Kimhae-Gun and Kimhae-Si in Busan, Dalsung-Gun, Chilgok-Gun and Kyungsan-Gun in Daegu, Hwasung-Gun and Raju-Gun in Kwangju, and Daeduk-Gun in Daejun. These results could be expected to have many implications for the establishment of area-wide public transportation network, the metropolitan transportation decision-making bodies and others.

The characteristic features of surface ozone concentration and the forecasting procedure of high ozone days have been studied. The ozone concentration was continuously measured during 3 years (1997~1999) at air quality monitoring stations in five major cities in Korea. The diurnal variation of surface ozone concentration on high ozone days is characterized by low ozone concentration at night. The ozone concentration Increases continuously after sunrise, In reach a peak at 1500~1600 LST. Thereafter it decreases steadily to a low concentration at sunset. The diurnal and annual maximum of the surface ozone concentration at Seoul were observed in May and June, respectively. The favorable synoptic condition for the high ozone day is divided into 4 different synoptic weather patterns: a high-pressure system from the Sea of Okhotsk, the Pacific subtropical high extending westward, a moving high-pressure system covering the Korean peninsula. and a synoptic system In front of a typhoon. Most of high ozone days occur under the high pressure system in Korea.

During the autumn of 1991, the water soluble sulfur content in litters of platanus orientalis on the street sides in seoul, pusan, taegu, taejeon, kwangji, ulsan and ch'unch'on cities were determined. The relationship between the water soluble s content in litters of p. orientalis and the traffic was analysed. The average content of water soluble s in litters of p. orientalis in pusan, taegu, taejeon, seoul, ulsan, ch'unch'on and kwangju cities were 0.71%, 0.60%, 0.66%, 0.58%, 0.50%, 0.43%, 0.38%, respectively. The correlation was not statistically significant between the s content in litters of p. orientalis is related to the traffic of each studied area. consequently the water soluble s content in litters of p. orientalis is supposed to be an indirect indicator of air pollution.

The aim of this study is to analyze the unique framework of Hong Kong brand and compare it to Seoul through examining the process of developing city brand visual identity, which is top-down. As Asian cities, the processes of developing their city identity system to be strong city brands have taken outstandingly different steps between two cities. Hong Kong has the strongest tourism attributes modernity, stability, attractiveness of tourism attributes. Hong Kong has the most competitive power. Korea is the least one. Hong Kong has made it as a good example of a city brand and proved it through tourism statistics which are one of visible branding results. Apparently, it gives us constructive suggestions to consider its steps for developing city brand identity.

Purpose: To identify the effects on tuberculosis mortality of a tuberculosis control program conducted at 108 community health centers in terms of structure and process. Methods: The dependent variable was tuberculosis mortality, and the independent variables were the structure(type of centers, staff, nurses, doctors, budget) and process(chest X-ray checking, immunization, case detection, health education, patients registering & managing) of the tuberculosis control programs at the community health centers. Data were analyzed using descriptive analysis and stepwise regression analysis. Result: Tuberculosis morality was positively correlated with type of centers(rural area)(p<0.01), but negatively correlated with type of centers(large cities) (p<0.01), (middle cities)(p<0.05), staff FTE(p<0.05), and number of nurses(p<0.05). Regression analysis indicated that type of centers(rural area)($\beta$=0.457) and case detection($\beta$=0.234) had a significant effect on tuberculosis mortality. Conclusion: Ultimately, this study will provide information to improve the effectiveness of tuberculosis control programs in community health centers.

Since late 1990's the urban decline phenomenon has risen in most provincial cities in Korea. Many lively discussions have also risen about how to revitalize declined urban center. In small cities, especially resident participation is very important to revive their old vividness. The study then reviewed literatures published from 1995 to 2007 regarding resident participation in urban center revitalization for community reinvigoration. This study consists of four parts. The first part defined concepts of community and of resident participation, and included discussion about resident participation codes. In the second part, the problems about community formation and community facilities were scrutinized through preceding researches. The third and last parts suggested some propositions and strategies to draw resident participation into urban center revitalization.
