  • Objectives: This study aims to investigate the correlations between the prevalence of allergic rhinitis (AR) and cytokines among elementary school children in an industrial city, Ulsan, South Korea, and to identify major environmental risk factors associated with AR prevalence. Methods: We conducted a case-control study in June 2009 and February 2010 in order to evaluate the relationship between AR and related cytokines. Data on physician-treated prevalence over the past 12 months and potential risk factors for AR were compiled through a questionnaire from a survey of 339 schoolchildren living in different urban environments. Logistic regression analysis was carried out with propensity score matched data (n=180) to assess the influences of cytokines (IL-13, IL-33, IL-4 and IL-5) on AR prevalence and to determine which environmental factors affected AR. Results: In univariate analysis, the AR prevalence was influenced by family history of AR (mother and siblings), environmental factors (odor condition and irritated symptoms of air pollution), and indoor allergens (D. farinae and D. pteronyssinus). The t-test demonstrated that eosinophils, Immunoglobulin E (IgE), and interleukins (IL-13 and IL-5) were statistically significantly different according to treatment of allergic rhinitis over the preceeding 12 months. The results of the multiple logistic regression analysis showed that a statistically significant association between several factors (such as irritated symptoms of air pollution (OR 4.075, CI 1.735-9.568), IL-13 (OR 0.825, CI 0.734-0.928), odor condition (OR 2.409, CI 0.908-6.389), and AR history of siblings (OR 2.217, CI 0.999-4.921)) and the prevalence of AR was found after adjusting for confounders. Conclusion: These results suggest that AR prevalence is significantly associated with cytokine level, genetic background, and outdoor environmental factors. Although living in a polluted area and genetic background can contribute to an increased risk of childhood AR, cytokine level should be considered as an important factor in the treatment of AR in the last 12 months.

  • Objectives: To compare the self-rated health in chronic disease patients with depression, chronic disease patients, and depression patients, and to observe the related factors to the self-rated health of people age 65 and older. Methods: The subjects were 2,549 elderly people, over 65 years old in Busan Metropolitan City who participated in 2009 community health survey. Association between self-rated health and general characteristics, life style and disease status were observed. Depressive symptoms were measured using the Centre for Epidemiologic Studies Depression Scale (CES-D). Analysis of complex sample was done with SAS (ver. 9.2), using χ2-test and multiple logistic regression. Results: Among total 2,549, there were 740 normal people (29.8%), 50 people with depression (1.8%), 1,495 people with other chronic diseases (58.2%), and 264 people with the comobidity of depression and other chronic diseases (10.1%). Good self-related health accounted for 20.3% for the whole, 33.4% for normal, 16.7% for chronic disease, 16.1% for depression, and 3.2% for chronic diseases with depression. Disease, gender, education, income, alcohol drinking, regular exercise and regular walking were independent factors associated with the good self-related health. Conclusions: It is suggested that when the chronic disease control program for the elderly is developed, depression care should be considered along with the program. This program should be given priority to the women and the vulnerable classes and should also be related to the regular walking.

  • This study examined the relationship between social support and the subjective well-being of the elderly living in urban areas. The study subjects were 382 elderly people aged 65 or older living in D metropolitan city. The survey was conducted through a personal interview by investigators who visited the study subjects using a structured questionnaire from May 1 to June 30, 2019. As a result, the subjective well-being of the study subjects differed significantly depending on various variables in the sociodemographic, health condition and, health-related behavior characteristics. The subjective well-being according to social support was significantly lower for the groups with lower social support. The correlation of subjective well-being and social support showed a significant positive correlation. Logistic regression showed that the risk of lower subjective well-being increased significantly in the group (Q1), where the total score of social support was very high (Q4). The above results suggest that the subjective well-being of the elderly living in urban areas was not only related to various variables in sociodemographic, health condition, and health-related behavior characteristics but also has significant relationships for social support. Therefore, it is necessary to develop detailed social support practices to improve the subjective well-being.

  • As entering the international construction market became more difficult than the past, ODA projects can be a breakthrough for domestic engineering companies to enter the international market. However, since many companies compete for limited projects, it is necessary to reinforce the competitiveness of bidding success. The competitiveness is the result of accumulating experience, reputation, and networking through partnering. Therefore, depending on which partnering strategy has been taken over a long period, the bidding success is decided. The objective of this study is to identify the effective partnering strategy for bidding success. For this, the World Bank bid results, focusing on consulting projects in Vietnam, are collected. Using the bid results, inter-firm network representing the partnering relationship is constructed and the Social Network Analysis is conducted. After then, by conducting the Logistic Regression Analysis, effective partnering strategies are suggested. The result shows that the diversification strategy is advantageous for transportation and city development projects and the concentration strategy is advantageous for water projects. The partnering strategy for the consulting project proposed in this study will be used as a reference for the domestic engineering companies to enter the Vietnam construction market in the future.

  • BACKGROUND/OBJECTIVES: Considering the high number of deaths from coronavirus disease 2019 (COVID-19) in Latin American countries, together with multiple factors that increase the prevalence of vitamin D deficiency, we aimed to determine 25-hydroxyvitamin D (25[OH]D) levels and its association with mortality in patients with critical COVID-19. SUBJECTS/METHODS: This was a prospective observational study including adult patients with critical COVID-19. Data, including clinical characteristics and 25(OH)D levels measured at the time of intensive care unit admission, were collected. All patients were followed until hospital discharge or in-hospital death. The patients were divided into those surviving and deceased patient groups, and univariate and multivariate logistic regression analyses were performed to determine independent predictors of in hospital mortality. RESULTS: The entire cohort comprised 94 patients with critical COVID-19 (males, 59.6%; median age, 61.5 years). The median 25(OH)D level was 12.7 ng/mL, and 15 (16%) and 79 (84%) patients had vitamin D insufficiency and vitamin D deficiency, respectively. The median serum 25(OH)D level was significantly lower in deceased patients compared with surviving (12.1 vs. 18.7 ng/mL, P < 0.001). Vitamin D deficiency was present in 100% of the deceased patients. Multivariate logistic regression analysis revealed that age, body mass index, other risk factors, and 25(OH)D level were independent predictors of mortality. CONCLUSIONS: Vitamin D deficiency was present in 84% of critical COVID-19 patients. Serum 25(OH)D was independently associated with mortality in critical patients with COVID-19.

  • The diversification of the New Deal urban regeneration projects, that started in 2017 in accordance with the "Special Act on Urban Regeneration Activation and Support", generated the increased demand for the accuracy of data-driven diagnosis and project type forecast. Thus, this research was conducted to develop an application model able to identify the most appropriate New Deal project type for "eup", "myeon" and "dong" across the country. Data for application model development were collected through Statistical geographic information service(SGIS) and the 'Urban Regeneration Comprehensive Information Open System' of the Urban Regeneration Information System, and data for the analysis model was constructed through data pre-processing. Four models were derived and simulations were performed through polynomial regression analysis and multinomial logistic regression analysis for the application of the appropriate New Deal project type. I verified the applicability and validity of the four models by the comparative analysis of spatial distribution of the previously selected New Deal projects by targeting the sites located in Seoul by each model and the result showed that the DI-54 model had the highest concordance rate.

  • The purpose of this study is to analyze the effect of neighborhood environmental perception on park use for health. The study area is focused on neighborhood parks in Suseong-gu, Daegu city. The analysis results are based on questionnaires of 303 respondents. According to the results, park use for health improvement was significantly associated with the perceptions of accessibility to a marketplace, availability of public transit, accessibility to the park, enough sidewalks, number of crosswalks, and athletic population. The probability of park use increased by 2.326 times as the satisfaction of accessibility to the park increased. Also, greater athletic population, fewer crosswalks, and more sidewalks lead to increase of park use by 1.701, 1.617, and 1.642 times, respectively. Therefore, it is important to increase the available neighborhood parks around residences and to develop exercise programs that people can use continuously in order to vitalize park use for health improvement. Also, it is necessary to improve the convenience of walking such as development of pedestrian streets or malls between residences and parks.
