Objective : This study explores whether and how the amount of smoking differs by economic status and perception among the men in working age. Methods : The study utilized the 4th wave of KoWEPS containing the items on perception of economic conditions. Analysis was conducted on ever-married men aged 30-54, who have capacity to work. It used 2 stage regression model methods to examine the mediation effect of perception on economic status. Results : The results shows that the negative perception on economic status has a positive effect on smoking. Disposable income affects smoking only through the perception of economic status. Employment status exerts both direct and indirect effect on smoking. Conclusions : These findings imply that less privileged economic status is related to smoking through anxiety or stress for the negative perception on it.

The 1995 tax reform in Korea has brought adjustment to the tax bracket, marginal tax rate, and tax deduction system which resulted in significant decrease in the income tax progressivity. In this paper we study the causal effect of the tax reform on male labor supply using difference-in-differences method. Using the data from Economic Active Population Survey (EAPS) and Daewoo Panel Data, we find about 1.5% increase in the hours worked of male wage workers.

The purpose of this study was to identify the multidimensional factors that affect the satisfaction of life by type of baby boomer generation. The subjects of this study were 1,895 households who were born from 1955 to 1963 among the respondents in the Korea welfare panel (the 10th year). The baby boomer generation was classified into four types such as gender, income status, male and female as socioeconomic status. The male type IV (B=.074, t=1.992, p<.05), health status (B=.233, t=7.268, p<.001), household income (B=.174, t=4.476, p<.001), depression (B=-.182, t=-5.242, p<.001), self-esteem (B=.255, t=7.027, p<.001), trust (B=.064, t=2.036, p<.05), etc. were found to have a significant effect on the life satisfaction of the male baby boomer generation. The female type IV (B=.100, t=2.598, p<.05), health status (B=.239, t=6.790, p<.001) (P<.001), depression (B=-.181, t=-5.142, p<.001), and self-esteem (B=.320, t=8.600, p<.001), etc. were found to have a significant effect on the life satisfaction of the female baby boomer generation.

본 연구는 성인 남성들의 비만도에 영향을 주는 요인을 사회 경제적, 건강관련 행동적 측면에서 규명하기 위하여 일개광역시 A부대에 2009년 4월과 5월에 입소한 장병 4,923명을 대상으로 건강관련 행태관련 설문조사를 한 후 비만도를 산출하고 비만과 관련 요인을 분석하였다. 입대전 가구의 월평균 소득이 비만과의 관련성에서 긍정적 효과를 주는 것으로 판단된다. 그러나 우리나라의 경우 아직까지 경제적 수준에 따른 비만의 유병률에 대한 일관성 있는 결과가 도출되고 있지 못한 실정으로 연령, 유전, 직업, 교육수준, 소득 등의 지표들을 사용한 비만과의 관련성에 대한 구체적인 후속 연구가 필요할 것으로 생각된다.

Purpose: This study was undertaken to evaluate the health, nutritional status and metabolic syndrome risk according to the dietary pattern of adult single-person households, using information obtained from the Korea National Health and Nutrition Examination Survey (KNHANES). Methods: Data were collected from the 2013-2016 KNHANES, of adults aged 19-64 years, belonging to single-person households. Based on cluster analysis, the dietary patterns of subjects were classified into three groups. The dietary behavior factors, health-related factors, nutritional status, and prevalence of metabolic syndrome obtained from KNHANES questionnaires were compared according to the individual dietary pattern. The nutrient intake data of the subjects were calculated using the semi-food frequency questionnaire. Moreover, blood and physical measurement data of the subjects were analyzed to obtain the prevalence of metabolic syndromes. Results: The major dietary intakes of subjects were classified as 'Rice and kimchi', 'Mixed', and 'Milk·dairy products and fruits' patterns. Characteristics of subjects based on their dietary pattern, gender, age, and education level were significantly different. The 'Milk and fruits' pattern showed low frequency of skipping breakfast and eating out, and had higher intake of dietary supplements. Frequency of alcohol intake and smoking rates were highest in the 'Mixed' pattern. Maximum nutrient intake of fat, vitamin A, riboflavin, vitamin C, niacin, calcium, phosphorus, and potassium was obtained in the 'Milk·dairy products and fruits' pattern. According to dietary patterns adjusted for age and gender, the risk of metabolic syndrome was 0.380 times lower in the 'Milk·dairy products and fruit' pattern than in the 'Rice and kimchi' pattern. However, when adjusted for other confounding factors, no significant difference was obtained between dietary patterns for metabolic syndrome risk. Conclusion: These results indicate that the health and nutritional status of a single-person household is possibly affected by the dietary intake of subjects.

This study analyzes the male-female difference in self-employment rates in Korea using panel data constructed from the Economically Active Population Survey in 1999. Given that most studies on self-employment have focused on male self-employment and have not examined why self-employment rate is usually higher among males than females, this study certainly extends the existing literature on this subject This study consists of two parts. The first part deals with estimating self-employment rates for males and female within a Markov framework. The second part presents decomposition results of the male-female differential in self-employment rates. Major findings of the study are (1) self-employment rate is higher for males than females because entry into self-employment is larger but exit from self-employment is smaller for males than female, (2) higher entry probability for males is due to differences in coefficients of transition probability functions while lower exit probability for males is due to differences in characteristics, (3) a large part of male-female gap in self-employment rates results from differences in being a head of family, marital status and age between males and females.

The main purpose of this paper is to examine selectivity and rasons for move of internal migrants in Korea. There have only been a few studies available on the issues of selectivity and reasons for move of internal migration in Korea, mainly due to the lack of appropriate data. The main source of data for this analysis come from the raw data set of the 1997 Special Migration Survey conducted by the National Statistical Office. Analysis of selectivity of those who moved across the provincial boundary revealed that females, young adults, singles in their marital status and more educated are more likely to move. Among various reasons for move, employment related reason is the most important for all migration streams. But with different migration streams, diverse patterns are emerged. For those who moved into the Capital Region, employment related reason is outstanding. But those who moved out from the Capital Region, moved for employment as well as family related reasons. For movement within the Capital Region, housing related reason is equally important together with employment and family reason. The analysis also found that among individual attributes, age and marital status affect most significantly to the reasons for move. Education level and housing ownership are also important for explaining for variations in reasons for move.

This study focus on unemployment and nonparticipation of youth. By dividing youth nonparticipants into 'house work and child care', 'studying and training', 'the others' categories, we estimate the potential wages with selectivity bias model and analyse the factors of choosing unemployment or nonparticipation with multinomial logit model. The differences between the potential market wage and the desired wage of the groups of 'studying and training', 'the others' in the nonparticipants are greater than those of the unemployment group. In the case of the man and lower age, and low schooling the differences of potential and desire wage are larger than woman and higher age, and high schooling. In the choice of unemployment and nonparticipation, man and higher age, and householder, and holder of qualification are not likely to opt nonparticipation. The experience of job lower the rate of probability to choose employment, but raise the rate of probability to choose unemployment and nonparticipation. These results mean that the quality of youth employment is very inferior.

This study aimed to assess the factors affecting the level of happiness and a sense of happiness among senior men and women, including sociodemographic characteristics, health behavior, subjective health level, and healthcare utilization, using the 2017 Community Health Survey (CHS). A total of 67,835 older adults were enrolled for the study, 27,979 males and 39,856 females. The results showed that education level and total household income affected the happiness in female elderly, while having a spouse increased happiness in male elderly. In addition, both male elderly and female felt a great of happiness when they had good health behaviors, perceived themselves to be in good health, and had no restrictions with healthcare utilization. Subjective health status and healthcare utilization seem to have a substantial impact on happiness because older adulthood is a period marked with increased physical vulnerability compared to other age groups due to diminished physiological functions. Based on these results, the government should expand subsidies for welfare for the aged to provide lifelong education opportunities and the existing elderly education and programs in health-related organizations should reflect the characteristics of the elderly. Furthermore, social service systems and programs related to the elderly should be re-evaluated so as to develop services and programs tailored to the elderly to promote their happiness more effectively.
