With a substantial rise in divorce rates since the mid 1990s, single-parent households are increasing rapidly in Korea. Often it is believed that children in single-mother households suffer the most economically and socially with the marital disruption of the parents. This study hypothesizes that in Korea the socioeconomic status of single-father households may be lower than that of single-mother households mainly because low-income divorced women are not able to form their own households with children. The analysis is based on two sub-samples from the 2% sample of the 2005 Census, one, with children 12 years old or younger and, the other, with divorced mothers of children of the same ages. The findings support the hypothesis that previously-married single fathers show the lowest educational and occupational status among 6 groups of parents: fathers and mothers from two-parent families, fathers and mothers from married but spouse-absent families, and previously-married single fathers and mothers. Divorced mothers'likelihood of living apart from their children has a strong negative association with their educational attainment, with the highest likelihood among women of middle school or lower education and the lowest likelihood among women with college education. Although single mothers comprise a larger percentage of single-parent households, single-father households demonstrate a particular vulnerability with their weak socioeconomic status.

Changes in the public welfare attitudes are very important to the welfare politics and policy. Considering that variability of public welfare attitudes has been ignored in previous studies, we analyzed welfare attitudes changes at individual level in Korea. Using the longitudinal data from the Additional Survey of 2010/2013/2016 Korea Welfare Panel Survey, we analyzed the changes in public welfare attitudes during 2010th-2016th years. Major findings are as follows. First, one of the findings from analysis is that the public welfare attitudes are very active and dynamic in Korea. This finding is contradiction to the results of the previous researches that are point to the stability or inertia of the public welfare attitudes in western welfare states and also in Korea. Second, occurrences of the welfare attitudes change are related with various individual characteristics; income status, occupation status, age, region, sex, political ideology, etc. These results from this study on the welfare attitudes change suggest that dynamics of the Korea welfare politics in recent years reflected the dynamic changes in public welfare attitudes. And, they suggest that Korea welfare politics are transformed from the traditional classes welfare politics to the new welfare politics which are influenced by various interests of the socio-demographic groups.

=Objectives: This study was conducted to evaluate the diferences in Farmer's syndrome between greenhouse-melon farmers and rice farmers. Methods: The study included 160 residents, who lived in rural community. Of those subjects, 73 and 87 from June 1 to July 30, 2006. Respondents were interviewed by means of a structured questionnaire. Results: This study showed that greenhouse-melon farmers had a lower average age, shorter experience of farming, more working hours per day than rice farmers (p<0.05). n farmers was 38.4% respectively, the prevalence in rice farmers was 22.6%. There was statistically significant diference in the prevalence of Farmer's syndrome between greenhouse-melon and rice farmers (p<0.05). The most frequent symptoms among eight symptoms that constitute the Farmer's syndrome were lumbago, shoulder pain and nocturnal urination regardless of type of farming. But greenhouse-melon farmers had higher prevalence of muskuloskeletal symptoms, such as lumbago and shoulder pain, than rice farmers (p<0.05).Conclusions: These results showed that prevalence of Farmer's syndrome was more common in the tools which reduce physical burden and take a rest and exercise periodically during work in the greenhouse-melon farmers.

The impact of the academic achievements of science high school graduates during the science high school period on their creative productivity, higher education, occupation, and income were investigated with 244 science high school graduates who belonged either to top 30% or bottom 30% in terms of their high school GPA. The factors contributed to the choice of current occupations and life were also investigated through retrospective approach. Survey questionnaire was administered to 244 adults who graduated from 18 science high schools before 2001. Thirteen graduates who completed questionnaire were interviewed face-to-face. Their ages ranged from 28.00 to 42.84. The high achievers were belonged to top 30% and the low achievers were belonged to the bottom 30% and the two groups demonstrated significant differences in their higher education and creative productivity. More doctoral degree holders and more number of creative products were found in the high achievers than the low achievers. 58.1% of the high achievers and 42.7% of the low achievers were working as professional scientists. Significantly more high achievers were working on tasks which require creative problem solving abilities and their income was significantly higher than the low achievers. For both groups, parents were the most significant individuals and then teachers were the second most important persons who impacted to their life and the choice of their occupation. Interviews with 13 graduates confirmed the survey results especially in their choice of life style and occupation. They were also influenced the most by parents, then teachers, and their friends who were more interacting with the socioeconomic environment when they selected university, major, and occupation. The results implies that high school achievement has significant influence on their future achievement to some extent and schools need to provide guide on the career choice not only to the students but also to their parents, since students' career choices are much influenced by their parents.

Purpose: The purposes of this study were to describe changes in weight, waist circumference (WC), and prevalence of obesity over 8 years as well as investigate demographic and dietary factors associated with weight gain in Korean adults. Methods: The Korean Genome and Epidemiology Study is an ongoing community-based longitudinal study, which was started in 2001~2002 and repeated every 2 years. Height, weight, and WC were measured, and demographic data and food intake information using the food frequency questionnaire were collected from 10,038 adults aged 40~69 years at baseline. Among those individuals, 3,506 healthy individuals without chronic diseases completed the 4th follow-up survey in 2009~2010. Results: Mean weight decreased by 0.35 kg and 0.65 kg in men and women, respectively, whereas mean WC increased by 1.71 cm and 1.85 cm during the 8-year period. Prevalence of obesity based on body mass index (BMI) decreased from 34.5% to 33.5% in men and from 38.0% to 36.7% in women, whereas abdominal obesity increased from 14.8% to 22.2% in men and from 28.8% to 35.4% in women. Weight change was associated with age and smoking status in men, and residence area, age, education, income, and alcohol drinking in women. Approximately 57.5% maintained their BMI over 8 years (<${\pm}1kg/m^2$, stable weight group), 19.5% showed a BMI increase of ${\geq}1kg/m^2$ (weight gain group), and 23.0% showed a BMI decrease of more than $1kg/m^2$ (weight loss group). There was no significant difference in energy intake calculated as the percentage of estimated energy requirements among the three weight change groups. Intakes of coffee mix and milk were significantly higher in the weight gain group than in the weight loss group in men after controlling for confounding factors. Conclusion: Our results show that higher consumption of coffee mix and milk was associated with weight gain in Korean healthy men.

This study was conducted to assess the equity in the regional insurance scheme through analysis of the computerized data from one regional insurance society and National Federation of Medical Insurance. We analysed the insurance contribution and benefit by the classes based on total and income-related contribution per household. The major findings of this study are as follows : 1. The average proportion of income-related contribution among the total was 39.2% and the upper classes show higher proportion of the income-related contribution. 2. The upper classes show higher health care utilization rate than the lower classes. It suggests that the lower classes have relatively large unmet medical needs. 3. The analysis through the Lorenz curve reveals that there exists transference of contributions from the upper to lower classes. But the cumulative percentage of insurance benefit is smaller than that of the number of the insured. It implies that regional medical insurance scheme in Korea has still some inequity in the context of social security principles.
