Background: Particulate matter (PM) is one of the leading causes of premature death worldwide. Previous studies in South Korea have applied a relative risk calculated from Western populations when estimating the disease burden attributable to PM. However, the relative risk of PM on health outcomes may not be the same across different countries or regions. Objectives: This study aimed to estimate the premature deaths and socioeconomic costs attributable to long-term exposure to PM in South Korea. We considered not only the difference in PM concentration between regions, but also the difference in relative risk. Methods: National monitoring data of PM concentrations was obtained, and missing values were imputed using the AERMOD model and linear regression model. As a surrogate for relative risk, hazard ratios (HRs) of PM for cardiovascular and respiratory mortality were estimated using the National Health Insurance Service-National Sample Cohort. The nation was divided into five areas (metropolitan, central, southern, south-eastern, and Gangwon-do Province regions). The number of PM attributable deaths in 2018 was calculated at the district level. The socioeconomic cost was derived by multiplying the number of deaths and the statistical value of life. Results: The average PM₁₀ concentration for 2014~2018 was 45.2 ㎍/m³. The association between long-term exposure to PM₁₀ and mortality was heterogeneous between areas. When applying area-specific HRs, 23,811 premature deaths from cardiovascular and respiratory disease in 2018 were attributable to PM₁₀ (reference level 20 ㎍/m³). The corresponding socioeconomic cost was about 31 trillion won. These estimated values were higher than that when applying nationwide HRs. Conclusions: This study is the first research to estimate the premature mortality caused by long-term exposure to PM using relative risks derived from the national population. This study will help precisely identify the national and regional health burden attributed to PM and establish the priorities of air quality policy.

Objectives: To date, studies have not comprehensively demonstrated the relationship between stroke incidence and socioeconomic status. This study investigated stroke incidence by household income level in conjunction with age, sex, and stroke subtype in Korea. Methods: Contributions by the head of household were used as the basis for income levels. Household income levels for 21 766 036 people were classified into 6 groups. The stroke incidences were calculated by household income level, both overall within income categories and further by age group, sex, and stroke subtype. To present the inequalities among the six ranked groups in a single value, the slope index of inequality and relative index of inequality were calculated. Results: In 2005, 57 690 people were first-time stroke patients. The incidences of total stroke for males and females increased as the income level decreased. The incidences of stroke increased as the income level decreased in those 74 years old and under, whereas there was no difference by income levels in those 75 and over. Intracerebral hemorrhage for the males represented the highest inequality among stroke subtypes. Incidences of subarachnoid hemorrhage did not differ by income levels. Conclusions: The incidence of stroke increases as the income level decreases, but it differs according to sex, age, and stroke subtype. The difference in the relative incidence is large for male intracerebral hemorrhage, whereas the difference in the absolute incidence is large for male ischemic stroke.

The prevalence of oral cancers (OC) is high in Asian countries, especially in South and Southeast Asia. Asian distinct cultural practices such as betel-quid chewing, and varying patterns of tobacco and alcohol use are important risk factors that predispose to cancer of the oral cavity. The aim of this review is to provide an update on epidemiology of OC between 2000 and 2012. A literature search for this review was conducted on Medline for articles on OC from Asian countries. Some of the articles were also hand searched using Google. High incidence rates were reported from developing nations like India, Pakistan, Bangladesh, Taiwan and Sri Lanka. While an increasing trend has been observed in Pakistan, Taiwan and Thailand, a decreasing trend is seen in Philippines and Sri Lanka. The mean age of occurrence of cancer in different parts of oral cavity is usually between 51-55 years in most countries. The tongue is the leading site among oral cancers in India. The next most common sites in Asian countries include the buccal mucosa and gingiva. The 5 year survival rate has been low for OC, despite improvements in diagnosis and treatment. Tobacco chewing, smoking and alcohol are the main reasons for the increasing incidence rates. Low socioeconomic status and diet low in nutritional value lacking vegetables and fruits contribute towards the risk. In addition, viral infections, such as HPV and poor oral hygiene, are other important risk factors. Hence, it is important to control OC by screening for early diagnosis and controlling tobacco and alcohol use. It is also necessary to have cancer surveillance at the national-level to collect and utilise data for cancer prevention and control programs.

Objectives : The purposes of this study were to examine the health-related quality of life(HRQoL) and to identify its related factors for a group of rural adults. Methods : The study subjects were 1,901 adults who were aged 40-70 years and who were living in Naju City, Jeollanamdo. The sociodemographic characteristics, health-related behavior, health status and global self-rated health were collected for statistical analysis. The health-related quality of life was measured by the Euroqol EQ-5D instrument. The differences on the EQ-5D index between the groups were assessed with t-test, ANOVA and hierarchical multiple regression analysis. Results : Overall, the mean value of the EQ-5D index was $0.884{\pm}0.140$ and this score was significantly different according to the socioeconomic characteristics, the health-related behavior, the health status and the global self-rated health. According to the results from the hierarchical multiple regression analysis, the HRQoL was significantly reduced for females, older subjects, and other subjects with no spouse and the subjects with osteoporosis, obesity, mental distress or poorer global self-rated health. Conclusions : The HRQoL for rural adults was related to the socioeconomic characteristics, the health status and the global self-rated health, A better understanding of the factors related to the HRQoL would help to improve the rural adults' quality of life.

Objectives: Previous pandemics have demonstrated that several demographic, geographic, and socioeconomic factors may play a role in increased infection risk. During this current coronavirus disease 2019 (COVID-19) pandemic, our aim was to examine the association of timing of lockdown at the county level and aforementioned risk factors with daily case rate (DCR) in the United States. Methods: A cross-sectional study using publicly available data was performed including Americans with COVID-19 infection as of May 24, 2020. The United States counties with >100 000 population and >50 cases per 100 000 people were included. The independent variable was the days required from the declaration of lockdown to reach the target case rate (50/100 000 cases) while the dependent (outcome) variable was the DCR per 100 000 on the day of statistical calculation (May 24, 2020) after adjusting for multiple confounding socio-demographic, geographic, and health-related factors. Each independent factor was correlated with outcome variables and assessed for collinearity with each other. Subsequently, all factors with significant association to the outcome variable were included in multiple linear regression models using stepwise method. Models with best R² value from the multiple regression were chosen. Results: The timing of mandated lockdown order had the most significant association on the DCR per 100 000 after adjusting for multiple socio-demographic, geographic and health-related factors. Additional factors with significant association with increased DCR include rate of uninsured and unemployment. Conclusions: The timing of lockdown order was significantly associated with the spread of COVID-19 at the county level in the United States.

Purpose - The elderly do not want to know what they want and what happiness is, and have no interest in their society. Thus, many studies have been made to investigate real-life situations and to find a solution. Further studies are needed to investigate the effect of the elderly's dating upon happiness. This study investigated the effects of the elderly's dating upon life satisfaction. Research design, data, and methodology - After coding, SPSS Win18.0 was used. The study was investigated as follows. The subjects were 530 elderly of 3 cities in Chungnam who live without children. A total of 512 questionnaire responses were used after we excluded 18 questionnaire because of incomplete responses. Results - The elderly's date value accounted for 3.22 of 5 in full. In this study, the interviewees (82.3%) said normal or higher level to be satisfied with the date. Conclusions - With the extended life span of the elderly, their chances to retain or make new partners have increased. Considering this trend, social workers and others in senior centers should give health services to the elderly to consult and give educational programs to be free from prejudice and conservative attitudes. Most of the elderly had desire to date but thought that with prejudice and bias.

The present study aims to phenomenologically investigate the adaptation experiences of Vietnamese immigrant women, with in the sociocultural context of their native country. In-depth interviews with a total of seven Vietnamese immigrant women were analyzed by the phenomenological method of A. Giorgi(1997). A total of 127 meaning units and 7 themes with 17 sub-themes, which rendered central meanings that indicated situational structures, were derived. The statements of situational structures were re-categorized in accordance with the sociocultural context of their native country. As the socioeconomic aspect, "aspiration for new opportunities and a new world" and "disappointment and frustration" were derived. The aspect of familial value and culture involved "conflicts over the unilateral acceptance of differences" and "building social relationships". The aspect of female status was associated with "conflicts due to patriarchal hierarchy". The aspect of child caring involved "education as a symbolic value" and the "double-sidedness of mother identity strategy". The gist of Vietnamese immigrant women's adaptation experiences is "to grow into a subjective mother despite conflicts due to the disappointment and frustration behind aspirations".

The purpose of this study is to Investigate the value of multi-culture and to examine how multi-culture has been reflected in men's fashion. As for the research methodology, literary research was under taken to study psychoanalytical and socioeconomic contexts in which multi-culture in men's fashion has been formed. In addition, demonstrative studies on styles were undertaken through the analysis of pictures and photos. The historical range of this study is from the 19th century when western and modern original form of men's dress were visualized, to the year 2001 when the elements of multi-culture are expressed in men's fashion. Westerners in 19th century respected Greek fine arts and the desire for realistic restoration of the body of Greek hero is well reflected in men's suits. Other races were forced to believe such realistic depiction of the Greek body as a symbol of modernization. With the advent of the Information Society In the late 20th century, absolute power had been decentralized, and people in the third world have revealed the racial contradictions by realizing the concept of splitted subject existing In unconscious. In the post-colonial world in the late 20th century, the value of diverse cultures is admitted. Models come from various races in fine art or photographic work Fashion trends are no longer limited to dominant mode, and designers express multi-culture by adopting and renewing folk elements from all over the world.
