Aiming to reveal the employment evolution around interstate highway corridors, an extended shift-share analysis is conducted for metropolitan areas in two interstate highway corridors on the U.S. east coast: I-95 and I-85. Our focus is on knowledge service sectors, specifically finance, insurance, business services and health services for two time periods, 1977-1990 and 1990-2005. In the first period, the two corridors' metropolitan areas have outperformed their regions in terms of both output and labor productivity. But this picture turned negative in later period with some variation by industries. Also variation in performance over time was found even in metropolitan areas in the same corridor or in geographically adjacent areas.

This research focuses on the fact that the characteristics of migration types of the youth in non-metropolitan areas vary by region and has the primary objective of comparing and analyzing the differences in determinants of each migration type. First, An exploratory analysis of the migration status and characteristics of the youth in non-metropolitan areas was conducted, and then a hierarchical logit model was used to estimate the determinants of migration types separately. The results showed that the characteristics of migration types vary by region, and each determinant of migration types is composed of different bundles of variables(individual and regional levels). In the future, policies aimed at securing young workforce in non-metropolitan areas will be more effective when they take into account various determinants of migration choices and reflect the regional context.

Objectives: The purpose of this study was to discover the changes in obesity prevalence and dietary habits in Korean adults residing in various residential areas during the last 10 years. Methods: Data on Korean adults aged 19 years and above was obtained from the 4th (2007-2009) and the 7th (2016-2018) Korea National Health and Nutrition Examination Survey. The subjects were classified into metropolitan (4th: n=5,977, 7th: n=6,651), urban (4th: n=4,511, 7th: n=5,512) and rural (4th: n=3,566, 7th: n=2,570) based on their residence. The general characteristics, nutrient intake, intake amount, food groups, and healthy dietary factors were analyzed. The association between residential areas and obesity prevalence were analyzed by multiple logistic regression. Results: In urban and rural areas, the obesity rate increased in the 7th survey compared to the 4th survey, excluding the metropolitan area. The carbohydrate intake decreased, and lipid intake increased in the 7th survey compared to the 4th survey. Over the same period, the intake of cereals and vegetables decreased, and the intake of meat and processed foods increased. Rural residents had a higher intake of cereals and vegetables, and a lower intake of milk and processed foods than those in metropolitan areas and urban residents. The proportion of subjects who practiced a healthy diet increased in the 7th survey compared to the 4th survey. In the 4th survey, there was no relationship seen between the prevalence of obesity and the subject's residential area, but in the 7th survey, the odds ratio of obesity was higher in rural areas than in the metropolitan areas, confirming the regional gap (OR: 1.16, 95% CI=1.00-1.36, P=0.044). Conclusions: This study showed that the obesity prevalence increased in rural residents compared to metropolitan residents, indicating a gap between the regions. The nutrient intake and intake of food groups changed in the 10 years under consideration, and there were differences seen between regions. Therefore, it is necessary to formulate a policy that will reduce obesity prevalence and health inequalities between regions.

The purpose of this study was to provide basic information on regional senior welfare policy setting for the elderly in the metropolitan and nonmetropolitan areas and on the development of senior welfare programs on the basis of the data of the 2019 community health survey conducted by Korea Disease Control and Prevention Agency. The subjects in this study were 74,547 senior citizens who were at the ages of 65 and over as of 2019 and who were 17,423 from the metropolitan area and 57,124 from the nonmetropolitan areas. The collected data were analyzed by SPSS version 26.0. The findings of the study were as follows: As for the levels of happiness in the metropolitan area, happiness was better in the seniors who were aged 75 and up, who had spouses, whose income was larger and who engaged in economic activity. In the nonmetropolitan areas, happiness was better in the seniors who were aged 75 and up, who were better educated, who had spouses, whose income was larger and who engaged in economic activity. In terms of health behaviors and subjective health levels, more happiness was felt by the seniors who didn't smoke at present, who didn't suffer any subjective stress, who were at higher subjective health levels and higher subjective oral health levels and who had unmet health care needs, no matter whether they dwelled in the metropolitan or nonmetropolitan areas. In the nonmetropolitan areas, however, engaging in intensive physical activity and lower BMI were identified as the factors to affect happiness.

Reform vs. Public Choice framework has long been a primary pattern for the debate on Organization of Government in Metropolitan Areas (OGMA). As one of the significant theoretical issues in contemporary Public Administration, the framework has reached at the state of intellectual impasse in that there seemed no decisive winner between the two camps[1]. In order to break this unentertaining balance, the article tries to reconstruct a theoretical conflation, a conceptual logic embedded in the conventional dichotomy. Moreover the result can help us start to imagine a system-like functioning of polycentric arrangement of local polities within a metropolitan region.

This study has the purpose to investigate the landscape plans focused on the public sector housing complexes in the Seoul Metropolitan Area in the 2000s. The targeted subjects of this study are 24 districts conducted by the Corporation, and the spatial extent is limited to Seoul metropolitan area. The scope of the research is limited to the public sector, because this sector has been conducted preferentially for public needs rather than the development profit, and has positively reflected the will "pre plan - post development". In view of the study methodologies, this study examined the transition process in Korea housing complex and analyzed the design reports to extract the key planning concepts and planning methods of landscape planning. The main concepts of landscape planning analyzed in this study were urban landscape, natural landscape, streetscape, architectural landscape, axis for viewing, landmark, skyline and landscape by areas. The key planning methods of landscape planning were landmark, which is a point landscape element, axis for viewing and skyline, which are linear landscape elements, landscape by areas which is an area landscape element, and finally complex landscape, walking landscape and nightscape, which are three-dimensional landscape elements.

The principal measure of housing demand is income and the preferences expressed by households through their respective indifference curves. In this context, housing essentially becomes a derived demand, i.e., the household consumes land and a location (or distance-in time and money costs), according to its relative preferences for space, accessibility, and all other nonhousing goods. This paper attempts to deal with both aspects of housing (apartment) demand and household mobility in the Seoul Metropolitan Areas. Housing services will be measured using hedonic regression technique. From observations on the market prices of dwelling units and on the underlying characteristics of housing, one can estimte the relationships between the two empirically. In predicting the probability of the future moves into new towns in the Seoul Metropolitan areas, the best predictors of the future moves into new best predictors are found to be the degree of satisfaction not only with the current residence as a whole, but with some of the major amenities, accessibility and child education. The reasons for moving into new towns are diverse depending on the households' current situation; the most frequently cited is "improvement of housing conditions," followed by "improvement of living environment," "asset improvement" and "home ownership". It appears that people move houses because of a dissatisfaction with their current housing status, relative their income or needs, or a desire to improve their housing and neighborhood amenities, or both. On the other hand, it is clear that the development of new towns in the Seoul Metropolitan Areas should be based on the analysis of housing demand and the pattern of household mobility in Seoul housing market.sehold mobility in Seoul housing market.

The necessity of compact high temperature superconducting cables is more keenly felt in densely populated metropolitan areas. Because the compact high-temperature superconducting cables can be installed in ducts and tunnels, thereby reducing construction costs and making the use of underground space more effective, the effect of introducing it to the power system will be huge. Seoul, Korea, is selected as a review model for this paper. The loads are estimated by scenario based on a survey and analysis of 345kV and 154kV power supply networks in this area. Based on this, the following elements for an urban transmission system are examined. (1) A method of constructing a model system to introduce high-temperature superconducting cables to metropolitan areas is presented. (2) A case study is conducted through the analysis of power demand scenarios, and the amount of high-temperature superconducting cable to be introduced by scenario is examined. (3) The economy involved in expanding existing cables and introducing high-temperature superconducting cables(ducts or tunnels) following load increase in urban areas is examined and compared., and standards for current cable ducts are calculated. (4) The voltage level that can be accommodated by existing ducts is examined.

Purpose: The ability to access clinical trials for cancer treatment is important. This study investigated whether regional differences exist in oncologic clinical trial protocols conducted in South Korea. Methods: Records of all approved oncologic clinical trials conducted in 2019 were downloaded from the Republic of Korea Ministry of Food and Drug Safety. The study covered Seoul, the capital area, other metropolitan cities, and provincial areas. Descriptive statistics summarized the distribution patterns of clinical trials by region. Results: A total of 202 oncologic clinical trials were conducted in 63 institutions in 2019. Of these protocols, 186 (92%) were available in Seoul, 120 (59%) in the capital area, 64 (32%) in metropolitan cities, and 66 (33%) in provincial areas. More regional differences in protocol availability were observed in domestic trials, investigator-initiated trials, phase 1 and 2 trials, and smaller-scale trials. Conclusion: Most oncologic clinical trials were conducted in medical institutions located in Seoul, with the rest conducted in the capital area, metropolitan cities, and provincial areas. The findings reveal clear differences in protocol availability between Seoul and the other regions. Measures designed to improve geographical access to oncologic clinical trials may be needed given their growing importance in cancer treatment.

To investigate the reason for the spatial difference in PM_2.5 (Particulate Matter, < 2.5 ㎛) concentration despite a similar synoptic pattern, a synoptic analysis was performed. The data used for this study were the daily average PM_2.5 concentration and meteorological data observed from 2016 to 2020 in Busan and Seoul metropolitan areas. Synoptic pressure patterns associated with high PM_2.5 concentration episodes (greater than 35 ㎍/m³) were analyzed using K-means cluster analysis, based on the 900 hPa geopotential height of NCEP (National Centers for Environmental Prediction) FNL (Final analysis) data. The analysis identified three sub-groups related to high concentrations occurring only in Busan and Seoul metropolitan areas. Although the synoptic patterns of high PM_2.5 concentration episodes that occur independently in Busan and Seoul metropolitan areas were similar, there was a difference in the intensity of pressure gradient and its direction, which tends to be an important factor determining the movement time of pollutants. The spatial difference in PM_2.5 concentration in the Korean Peninsula is due to the difference and direction of the atmospheric pressure gradient that develops from southwest to northeast direction.
