This paper measures and maps multi-dimensional residential segregation of immigrants in Seoul metropolitan area at city/county/district level as well as town level, thereby adding to our understanding of the urban structure and its spatial distribution impacted by immigration. The perspective offered here focuses on the segregation spurred by transnational migrants and their urban settlement. By drawing population data for 79 city/county/district administrative units from the Korea Immigration Service, residential segregation of immigrants in Seoul metropolitan area is measured based on Massey & Denton's four segregation indices: evenness, exposure, concentration and clustering. The empirical findings suggest that Seoul metropolitan area is highly segregated and the areas showing hyper-segregation appear in Seoul city and Gyeonggi province. As immigrants are foreseen to continue to increase in the future, this research contributes both empirically and theoretically to preliminary research on spatial segregation of immigrants by showing how ethnic places are segregated spatially through ethnic networks that support the geographic concentration of minority groups.

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.

Looking at the current status of beverages sold from vending machines in subway stations in Seoul, it was found that carbonated beverages accounted for the highest percentage of beverages on sale in vending machines, representing 36 % of all beverages sold. Survey respondents purchased carbonated drinks or sports drinks containing high levels of sugar to quench their thirst. Investigation of the sugar content of beverages frequently sold in vending machines showed that a serving of carbonated beverage contained an average of 30.4 g of sugar, or as much as 50.1 g of sugar (equivalent 10 to 17 cubes; 1 cube = 3 g of sugar). This amount corresponded, on average, with 60 % of the WHO recommended daily sugar intake (50 g). Surprisingly, with certain carbonated beverages, drinking a single can is equivalent to consuming the total recommended daily sugar intake of 50 g.

Purpose: This study was conducted to provide basic data for college students living in the Seoul metropolitan area to prevent the spread of infectious diseases and explore countermeasures by identifying the degree of difference with anxiety, stress, and preventive health behavior before and after the COVID-19 vaccination. Methods: Data were collected from the subjects of the study, 192 college students aged 19 to 29 who completed the COVID-19 vaccination in the Seoul metropolitan area. The data were analyzed with the correlation, paired t-test, and independent t-test using the SPSS 27.0. Results: Preventive health behavior, health anxiety, and stress showed the positive correlation before and after the COVID-19 vaccination among the college students. After the COVID-19 vaccination, COVID-19 related stress including fear of infection (d=-0.11±0.09), and difficulty in social distancing (d=-0.21±0.08), and health behavior (d=-0.06±0.44) decreased compared to before the vaccination. Conclusion: Health education and health policies are required to continue preventive health behavior even after the vaccination.

In this study, we identify the variables that affect the number of crime and spatial correlation in the Seoul metropolitan area, in addition, we measure the relative risk on the incidence of crime by a Poisson regression model. We suggest a statistical methodology to make a risk map for crime based on relative risk instead of the total event of crime by region using the Geographic Information System. To demonstrate the use and advantages of this methodology, this study presents an analyses of the total crime count in 25 wards in the Seoul metropolitan area.

This study investigates the diurnal pattern of transit ridership in the Metropolitan Seoul area. For the purpose, we use a weekday Smart Card passenger transaction data in 2005. Eleven passenger trip patterns are found from 2.74 million passengers moving on the Metropolitan Seoul Metro system. Among them, we analyze 2.4 million passengers blonging to five trip types having only one or two transaction record during a day. A total of 357 metro stations are classified to four types according to their diurnal pattern of passenger riderships. We analyze the relationships between passenger's trip chain patterns and subway station's diurnal transit ridership patterns. The result shows that the ratio of the number of passengers of particular time of the day is hierarchically related with trip chain patterns.

This study investigated whether there were statistical differences in the three categories of cosmetics brand preference- brand preference, gift brand preference, and preference for purchasing expensive cosmetics by the consumers' residence. For the data analysis, the types of cosmetics include basic and color, the cosmetics brands include domestic and imported cosmetics. The consumers' residence include metropolitan and non-metropolitan areas. The study collected the data from 477 surveys from adult women ranging from the age groups of 20s to 50s and above in 2011. Using SPSS Version 18.0 the data was analyzed by Frequency analysis, t-test. The study results were as follow: There were significant differences in the three patterns of cosmetics brand preference depending on the consumers' residence. The three patterns of preferences were in the similar trends. The results revealed while the non-metropolitan residents showed a higher level for the domestic brands, a lower level in the three categories of preferences for imported brands compared to their metropolitan counterparts in both types of basic and color. In contrast, compared to the non-metropolitan counterparts, the metropolitan residents showed a lower level of preferences in all of the three categories of cosmetics brand preference for domestic in both types of basic and color.
