The present study investigates the effects of lopsided regional policy and social prejudice on homeownership disparities by household's place of birth of household head in Seoul. The present study utilizes individual household-level census data (2% sample) to evaluate households' residential well-being denoted by homeownership status during the period of 1980-2000. Decomposition techniques based on tenure choice models were used to provide evidences of the home-ownership disparities caused by regional policy and prejudice. We found that households from Gangwon and Honam provinces represent a disproportionately small percentage of homeownership compared with those originated from other provinces. In the statistical analysis, the present study found that having controlled for the factors traditionally thought to influence households' choice of housing tenure, as well as other housing market characteristics in Seoul, place of birth has played a primary role in determining whether or not households become a homeowner. Most strikingly, while most of the disparity in homeownership ratios between households from Youngnam and households from Gangwon in the housing market is due to the endowment differences in human capitals they bring to the market, those between households from Youngnam and households from Honam is largely due to residual differences explained mainly by social discrimination and prejudice against people from Honam. The present study summarized that place of birth has played a primary role in determining whether or not households become a homeowner in Korea. The present study concluded with some policy issues relevant to this study and suggested some future studies.

The purpose of this study was to investigate the regional differences in food preference among college students participating in a nutrition education program via internet. The subjects were 1672 college students (male: 762, female: 910) and divided into 4 regional groups. A survey using a self-administered questionnaire was conducted using a self-administered questionnaire on taste and food preferences. Data was collected via internet or by mail. Prevalence of the food preferences among regional groups was examined using SPSS statistical package. Food preferences were significantly associated with sex and region. Female students in Chungcheong and Kyungsang areas showed significantly higher preference of the hot taste compared to Seoul and Kyunggi areas. Female students in Seoul, Kyunggi and Chungcheong areas showed significantly higher preference of the boiled bean rice compared to the Kyungsang area. The preference for Kimchi stew of female students in Seoul and Kyunggi was significantly higher than those in Chungcheong and Kyngsang areas. Male students in the Chungcheong area showed significantly higher Preferences of the Young radish kimchi, while female students in this area showed significantly higher preference of the Radish kimchi compared to other areas. The preference for roasted laver of female students in Seoul, Kyunggi and Kyungsang areas was significantly higher compared to the Chungcheong area. The preference for fried chicken of male students in Seoul was significantly higher than that in other areas. The preference for bean sprouts and season bonnet bellflower of male students in Seoul, Chungcheong and Kyungsang areas were significantly higher compared to the Kyunggi area. Therefore, these results Provide nation-wide information on food Preferences among Korean college students. (Korean J Community Nutrition 10(6) : $845\∼859$ 2005)

Background: A skin temperature difference is one of the variables used in the diagnosis of complex regional pain syndrome. However, there have been no reports as to whether the real (${\Delta}T$) or absolute value ($|{\Delta}T|$) of skin temperature differences should be used in the diagnosis of complex regional pain syndrome. This study was conducted to compare the diagnostic validity of ${\Delta}T$ with $|{\Delta}T|$ for complex regional pain syndrome using receiver operating characteristic curves (ROC). Methods: Infrared thermographic images were obtained from the 144 patients who were suspected to have CRPS in a unilateral limb. After ${\Delta}T$ and $|{\Delta}T|$ calculation from the thermographic image, ROCs of ${\Delta}T$ and $|{\Delta}T|$ were developed, and the areas under the curve (AUC) for the ROC curves were compared. Results: AUCs of ${\Delta}T$ and $|{\Delta}T|$ were 0.520 and 0.746 respectively, this difference was statistically significant (P < 0.001). Conclusions: Absolute skin temperature difference shows greater validity in the diagnosis of CRPS than ${\Delta}T$. Therefore, $|{\Delta}T|$ is more useful when comparing the skin temperature of CRPS patients.

This article examines how and why entrepreneurship differs by region concerning the history of Korea's entrepreneurial ecosystems (EEs). Through a qualitative analysis of 19 interviews, this article compares the history and components of Seoul National University and KAIST (Korea Advanced Institute of Science and Technology) EEs. First, these ecosystems emerged around 1996 and are currently experiencing the second startup boom, with various supporting organizations and actors involved. Second, these ecosystems revealed differences concerning material, social and cultural attributes. Third, differences in the networking of the two ecosystems are due to different regional cultures, which allow individuals to interpret entrepreneurial opportunities. In other words, the maintenance and development of EEs are cultural in essence and display regional variation.

Objectives: This study examined the changes in dietary habits, the prevalence of chronic diseases, and mental health problems in the regional areas of the Republic of Korea before and after the COVID-19 pandemic to provide evidence of the status of regional health inequalities. Methods: This study analyzed Korean adults aged 19 or older who participated in the Korea Community Health Survey (n = 686,708) and Consumer Behavior Survey for Foods (n = 19,109) from 2018 to 2020. The participants were classified according to their residence area (Seoul metropolitan area, Metropolitan cities, Provinces); 2018-2019 were defined as before COVID-19, and 2020 as after COVID-19. The dietary behaviors, chronic diseases, and mental health problems were measured using a self-report questionnaire. Results: After COVID-19, the eating-out usage rate in the Seoul metropolitan area and Provinces decreased compared to before COVID-19 (P < 0.001), and when responding that they eat out, the frequency of eating out with household members in the Seoul metropolitan area increased (P = 0.024). The deliveries/takeout usage rate in the Provinces decreased after COVID-19 compared to before (P < 0.001). After COVID-19, the prevalence of obesity decreased in all regions (P < 0.001), and the prevalence of hypertension increased significantly in the Provinces (P = 0.015). The prevalence of diabetes mellitus increased continuously before and after COVID-19 in all regions (P < 0.002). High-risk subjective stress levels increased significantly in the Seoul metropolitan area (P < 0.001), and sleep duration significantly increased in all regions (P < 0.001). Major depressive disorder was reduced significantly in Metropolitan cities (P = 0.042) and Provinces (P < 0.001). Conclusions: After the COVID-19 pandemic, the prevalence of chronic diseases and mental health problems showed regional differences along with changes in dietary habits. It is necessary to reflect the regional differences in dietary habits in future policies resolving regional health inequalities.

This study analyzed the regional effects on the poverty status of households and the poverty difference between Metropolitan and Non-metropolitan area in Korea. The Korea Welfare Panel Study was used for the study, and the results are as follows. First, the poverty rate of Non-metropolitan area is higher than Metropolitan area, and the poverty rate of small-sized regions is the highest area among Non-metropolitan areas. It shows that the poverty of regions is deeply related with the development of region. Second, the people living in Non-metropolitan area have experienced more hardships than the people of Metropolitan area, even though they have similar socio-demographic characteristics. It implies that living in the Non-metropolitan area is to have much more risk of poverty. Third, the regional effects on the poverty are found, that is, living in Non-metropolitan areas is positively associated with the poverty probability. Lastly, regional effect, that is the differences of the poverty probability between Metro and Non-metropolitan areas, is estimated as $49.2{\sim}73.7%$ of total poverty differences. Results of this study suggest that regional poverty policies are necessary to solve the regional differences of poverty in Korea.

This study is designed to measure the relative efficiency of regional fishery cooperatives based on Data Envelopment Analysis(DEA) methods. Selecting 40 regional fishery cooperatives in Busan as Decision Making Units (DMUs), the study uses their panel data from 2007 to 2008 to rank the relative efficiency of the DMUs. First, the efficiency score of the DMUs are calculated using CCR, SBM, and super-SMB model. Within the model, input variables are the number of employees and area of fishery cooperatives. Output variables are the amount of deposit money, loan and profit. Based on the efficiency scores calculated from super-SMB model, the efficiency ranking of the DMUs is determined. Second, the differences in average efficiency calculated from the three DEA models are tested using a pair-wise mean comparison test. The results based on the efficiency scores evaluated from super-SMB model show that seven out of the forty DMUs are efficient; among the efficient DMUs, the DMUs that can be benchmarked for inefficient DMUs through the frequency analysis of reference set being identified. Third, the differences in average efficiency of the three DEA models between 2007 and 2008 are tested using pair-wise mean comparison test and the study estimates the efficiency change of the DMUs between 2007 and 2008 using Malmquist productivity index(MPI). Finally, the paper suggests an improved composite DMU superior to the inefficient DMUs evaluated by Super-SBM model.

The traditional methodology of Korean regional studies had been shifted by geographic thoughts and philosophy as follows; Environmentalism or Environmental determinism stemming from geomancy were dominant methodology in the Korea era. An idiographic approach was introduced based on the encyclopedic description of geographic factors of villages for the centeralization of power in the Chosun era. A systematic geography that pursues scientific laws of regional differences which results from the interactions of human and nature had emerged through field works of some practical school in the later Chosun era.

The purpose of this paper is to visualize and to analyze differences of regional mortality rates by major causes of death. We use causes of death statistics from KOSIS and compare regional mortality rates divided by national mortality rates by three causes of death. To do this, we define regional mortality ratio and regional age-standardized mortality ratio, and visualized by choropleth map using R. As a result, In case of neoplasm, there was no significant difference by region. In case of circulatory system, Ulsan, Daegu, Busan and Gyungnam showed relatively high regional age-standardized mortality ratio. In case of respiratory system, the ratios were in order of Gangwon, Sejong, and Chungbuk.
