Objectives : Vigorous physical activity is a well-known method to promote people s health. This research aims to investigate whether perceived neighborhood characteristics affect vigorous physical activity among adult Seoul residents (aged 19 to 64). Methods : Utilizing the 2005 Seoul Citizens Health Indicators Survey data, this study estimates the probability of vigorous physical activity. Particular attention is given to the effects of three perceived neighborhood characteristics satisfaction with relationship to the neighborhood, satisfaction with park and recreational facilities, and satisfaction with public security). Logistic regression models are analyzed separately by gender for the parameter estimation. Results : Vigorous physical activity is positively associated with three perceived neighborhood characteristics for women, while neither significant nor substantive association is found for men. Conclusions : As vigorous physical activity among Seoul citizens is differentially affected by perceived neighborhood characteristics and by gender, a different approach will be needed to increase vigorous physical activity of men and women in Seoul.

In Korean society, a housewife and mother often plays the role of family resource manager. In 2008, the newly appointed Korean government proposed a new direction in social policies, including family policy, that is, "active social welfare". According to "active social welfare", family policy focuses on a preventive policy and a family needs-oriented policy. In other words, newly established family policies should reflect parents' needs in their family resource management. In this economic downturn, family policies should be established to satisfy parents' needs to overcome their own family's economic crisis. This study focuses on policy recipients' real voices and their needs: they need the government's help supporting their efforts to overcome the economic crises within their families.

Traditional mediation analysis, which relies on linear regression models, has faced criticism due to its limited suitability for cases involving different types of variables and complex covariates, such as interactions. This can result in unclear definitions of direct and indirect effects. As an alternative, causal mediation analysis using the counterfactual framework has been introduced to provide clearer definitions of direct and indirect effects while allowing for more flexible modeling methods. However, the conceptual understanding of this approach based on the counterfactual framework remains challenging for applied researchers. To address this issue, the present article was written to highlight and illustrate the definitions of causal estimands, including controlled direct effect, natural direct effect, and natural indirect effect, based on the key concept of nested counterfactuals. Furthermore, we recommend using 2 R packages, 'medflex' and 'mediation', to perform causal mediation analysis and provide public health examples. The article also offers caveats and guidelines for accurate interpretation of the results.

Objectives: The purpose of this study was to assess predictors of health-related quality of life (HRQoL) in elderly Asian American and non-Hispanic White cancer survivors. Methods: We conducted cross-sectional secondary data analyses using the combined datasets from the Surveillance, Epidemiology, and End Results program and the Medicare Health Outcomes Survey. Results: Elderly Asian American cancer survivors reported a lower mental HRQoL but a comparable physical HRQoL relative to elderly non-Hispanic White cancer survivors. Stress factors, such as comorbidities, difficulties with activities of daily living, and a history of depressive symptoms, along with coping resources like self-rated health and the ability to take the survey in English, were significantly associated with mental and physical HRQoL. Among elderly Asian American cancer survivors, a significantly lower mental HRQoL was observed among those taking the survey in the Chinese language. Conclusions: The findings suggest that race exerts a differential impact on HRQoL. Interventions should be designed to address the distinct cultural, linguistic, and systemic needs of elderly Asian American cancer survivors. Such an approach could assist in reducing cancer-related health disparities.

As a result of cost-benefit analysis by making a macroscopic approach to the health screening projects conducted 4 times since 1950 for the insured people of the Korea Medical Insurance Corporation, the following conclusions were reached. 1. The direct costs put into the health screening project, and the time costs which were paid by examinees or calculated in terms of social costs have been estimated. The results is that the lowest estimation was 10,337 million won and the highest 15,141 million won when a minimum of 1.5 hours of time spent and a maximum 4 hours were applied. 2. In terms of the psychiatric benefits, the lowest estimation was 5,341 million won while the highest was 5,585 million won. 3. In terms of the benefits for each kind of diseases, the lowest estimation of 37,188 million won and highest estimation of 74,383 million won have been calculated for the liver diseases. And for the cardiovascular diseases, the minimum estimation was 14,475 million won while the maximum was 20,532 million won. In case of pulmonary tuberculosis, with external effect benefits being included, the estimation ranged from the minimum of 1,649 million won to the maximum of 1,832 million won. And the estimation of benefits for diabetes mellitus and renal diseases ranged from 89 million won to 92 million won and from 4,567 million won to 7,598 million won respectively. 4. In comparing costs and benefits, as a results of comparing each highest and lowet estimation a range of minimum 46,708 million won and maximum 98,071 million won of benefits has been gained.

This papaer discusses the recent tendencies of health approach in the developed countries and suggests the strategy of health approach in order to cope with the changing environmental conditions of Korea in 2000's. In 2000's, Korea will have the environmental conditions and health problems similar to those of the developed countries at present. The American and European developed countries have shown the integrative approach trend by the interdisciplinary cooperation based on the holistic health conception, for example, as in the behavioral medicine, with the active drive of the medical self care movement and the national health preactice movement. The basic solution to the 2000's main health problems such as high morbidity of chronic diseases and high medical expenditure is to decrease the health need through the health promotion, disease prevention and early. ditection and early treatment of disease. The above actions need to induce the public to change their health behavior in the desirable direction through the national health practice movement and the health self care movement. The succeed of the movements depends upon how to use effectively the mass media, health and administrative organizations, schools, industrial and medical insurance organizations with the strong government support of health and preventive policies and programs.

Objectives: Parkinson's disease is one of the most common neurodegenerative diseases in the elderly population. In order to estimate the prevalence of Parkinson's disease in the community, the application of a good screening tool is essential. We evaluated the validity and reliability of a Parkinson's disease screening questionnaire and propose an alternative measure to improve its validity for use in community surveys. Methods: We designed the study in a three-phase approach consisting of a screening questionnaire, neurologic examination, and confirmatory examination. A repeated survey was administered to patients with disease detected in the community and on 150 subjects. We examined internal consistency using Cronbach's alpha test, test-retest reliability using the kappa statistic, and validity using sensitivity, specificity, and ROC curves. Unadjusted odds ratios were utilized for the estimation of weights for each questionnaire item. Results: The Cronbach's alpha of the questionnaire was 0.708. The kappa statistic for test-retest reliability was good to generally fair in most of the items. When newly proposed weighting scores were used, the optimum cut-off value was 7/8. When cut-off value was 5/6 for surveying prevalence in a community, the sensitivity was 0.98, and the specificity was 0.61, with simultaneous improvement in reliability. Conclusions: We recommend 5/6 as the ideal cut-off value for the survey of PD prevalence in community. This questionnaire designed for the Korean community could help future epidemiologic studies of PD.
