This paper attempts to compare and analyze the intensity, trend, and regional gap of income inequality, capitalizing upon the Age-Period-Cohort model which considers age, time and cohort effects, with the 1998-2018 Korea Labor Panel (KLIPS) survey data for respondents living in the Capital and Non-Capital Regions. The main analysis results are as follows. First, in the case of both cohort and age effects, those in their 50~60s, including the so-called baby boomers and '386 generation' living in the Capital Region, have relatively lower income inequality effect compared to that of other age groups and cohorts in the Non-Capital Region. Second, the micro-individual characteristics cannot be ignored to account for a regional gap in income inequality, but rather the effects of structural and institutional omitted variables and the social discrimination effects of individual characteristics variables are more significant in explaining it. Overall, intra-and inter-cohort income inequalities appear to overlap.

This study aims to address the effect of income on depression of Korean babyboomers according to gender. It also was to identify the moderating effect of social capital on the income-depression relationship. Researchers conducted a secondary data analysis using 6th wave of Korea longitudinal study of ageing collected in 2016. Researchers found gender differences of factors affecting depression. While, in the male model, income was not a significant factor predicting depression, it was a statistically significant factor to depression of female babyboomers. In addition, a moderating effect was found in the female model that advocacy and non governmental organization activity moderated the income-depression relationship. Therefore, it is necessary to consider gender differences for policy and service development; in specific, researchers suggest expanding elderly jobs for female babyboomers and support groups for male babyboomers.

Objectives: To investigate the drinking behavior and related factors of community residents in G city. Methods: Examination was executed with questionnaire to 1973 adults. Data were collected from October 1, 2005 to November 16, 2005. Drinking behavior involves rate of drinking, frequency of drinking, age of starting drinking, drinking amount, rate of attempts to drink moderately and reasons for reducing drinking. Related factors involves the general characteristics, the habits of health behaviors. This was analyzed with frequency, percentage, mean, standard deviation, x2-test, t-test, ANOVA and logistic regression. Results: The drinking rate of the respondents was 67.4%, that rate of male was 83.1%, while that rate of female was 52.5%. The drinking rate was higher in groups of younger aged and highly educated people than that rate of the other groups. The highest level of drinking frequency was ones or twice a week. The drinking frequency of those who drank more than three times weekly was higher in the groups of male, old aged, married people, low educated people, rural residents, farmers or fisherman or laborers and those who unemployed or who did not exercise frequently and control their body weight. These individuals also preferred salty food and meat and fish, dined out frequently, did not visit dental clinic regularly, and tend to be smokers. The mean of the age of starting drinking was 21.17 year-old, that of males was 19.94 year-old, that of females was 22.82 year-old. The mean of the age of starting drinking was lower in groups of male, young aged, unmarried, college educated, rural residents, clerks, high monthly income, healthy and no illness, and smokers than that of the other group. The average of the drinking amount was 5.77 pack, that of males was 7.41 pack, and that of females was 3.31 pack. The drinking amount is much more in groups of males, fifties, unmarried, college educated, rural residents, self-employed, healthy people, and smoker than the other. 33.4% of the respondents attempted to drink moderately.

The rental housing market in South Korea, specifically monthly rent with deposit, has been expanding over the last three decades (8.2% in 1990 to 21.0% in 2020), partly replacing the traditional Jeonse market. The distribution of rent has changed due to public rental subsidies and the emergence of luxury rental housing, while the distribution of rental household income has been polarized because of the emergence of rich renters. This study attempts to measure the structural changes in the rental market by developing a new indicator of income-rent mismatch. Using the seven series of the Korea Housing Survey, this study analyzed the changes in rent (reflecting the conversion rate) and income levels of rental households in 2006 (base year) and 10-15 years later (the analysis year) at the national level and at the spatial unit of 16 metropolitan cities and provinces (excluding Sejong), respectively, by dividing them into quartile data. The result reveals that rental housing was undersupplied in middle- and high-income rental housing due to the decline in the highest quartile (25%→18%) and the third quartile groups (25%→20%), while the supply of public rental housing expanded for the second quartile (25%→28%) and the lowest quartile (25%→35) groups. On the demand side, the highest income quartile shrank (25%→21%), while the lowest income quartile grew (25%→31%). Comparing the 16 metropolitan cities and provinces, there were significant regional differences in the direction and intensity of changes in rent and renter household income. In particular, the rental market in Seoul was characterized by supply polarization, which led to an imbalance in the income distribution of rental households. The structural changes in the apartment rental market were different from those in the non-apartment rental market. The findings of this study can be used as a basis for future regional rental housing markets. The findings can support securing affordable rental housing stock for each income quartile group on monthly rent and developing housing stability measures for a balance between income and rent distribution in each region.

This study analysed the income-related health inequality of the aged in Korea applied to EQ-5D. Two decompositions were used in analysis. One was the decomposition of income-related health inequality into six different dimensions of EQ-5D, and the other was to decompose it by sub-group such as sex, region, existence of spouse. The results are summarized as follows. First, the health concentration index(CI) of the aged was .0254, which meant that there were pro-rich inequality in elderly people's health levels. The same patterns were also seen in the analysis of different dimensions of EQ-5D such as mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Second, mobility accounted for 35.8% of total EQ-5D score, most contributing to CI of the dimensions of EQ-5D. The CIs by the dimensions ranged from .0091 for mobility to .0013 for self-care. Third, The decompositions by sub-groups showed that the contributions of sex, region, and existence of spouse to health inequality was similar to each other, all of three sub-groups accounted for 10 % of inequality respectively. Fourth, the inequality within group was higher in female group, rural area, and the aged without spouse. The average health level of these groups was lower than that of the other ones, too. These facts indicated that old women, the aged without spouse, and the elderly in rural area were the most vulnerable groups in health problems. Therefore, it is necessary to pay more attention to health problems of these groups in the policy making of health security and social welfare services.

Objectives: The purpose of this study was to examine the biochemical characteristics and dietary intake of adolescents aged 12 to 18 years according to the frequency of milk consumption. Methods: Data from the 2010~2011 Korea National Health and Nutrition Examination Survey was used for the study. The study examined adolescents' (12~18 years) demographic characteristics (house income level, residence region, skipping or not-skipping of breakfast/lunch/dinner, eating-out frequency), anthropometric characteristics (height, weight, weight status), biochemical characteristics (fasting plasma glucose, blood urea nitrogen, creatine, triglycerides, cholesterol, HDL-cholesterol, hemoglobin, hematocrit) and nutrient intakes through quantitative and qualitative evaluation using the Korean Dietary Reference Intakes (KDRI), index of nutrition quality (INQ), nutrition adequacy ratio (NAR) of 3 groups (< 1/week, 1~6/week, ≥ 1/day) according to the frequency of milk consumption. Results: There were significant differences in gender and income levels among the 3 groups. There were no differences in height, weight, and weight status among groups. There were differences in biochemical characteristics and nutrient intake. In boys, there were differences in the mean of BUN and HDL-cholesterol, in quantitative intakes of riboflavin, calcium, phosphorus, potassium by KDRI levels, in qualitative intakes of riboflavin, calcium, phosphorus by INQ and riboflavin, calcium, phosphorus by NAR among 3 groups. In girls, there were differences in the mean of blood urea nitrogen, creatine, HDL-cholesterol, in quantitative intakes of protein, riboflavin, calcium, phosphorus by KDRI levels, in qualitative intakes of riboflavin, calcium, phosphorus by INQ and riboflavin, calcium, phosphorus by NAR among the 3 groups. Conclusions: In Korean adolescents, boys had a higher frequency of milk consumption than girls, and higher the income level, higher the frequency of milk consumption. Consumption of milk appeared to have a positive association with triglycerides, HDL-cholesterol, and indices related to muscle mass. Regular consumption of milk is an important factor in enhancing the intake of riboflavin, calcium, and phosphorus, which adolescents lack. The results of the study indicate a need to prepare an environment and education program to increase milk consumption in adolescents at home and school.

The purpose of this study was to identify the relationship between clothing Brand Loyalty and lifestyles The questionnaire was administered to 644 males and females aged 30-40 in Taegu during November 24 to November 28 of 1997. Data was analyzed by frequency, percentage, mean, standard deviation, factor analysis, reliability test MANOVA and ANOVA by using SPSS package. 1. The lifestyles of the responednts were classified into five types such as consumption-oriented, economics-oriented, social-oriented, family-oriented, and conservative-oriented type. 2. The results of clothing Brand Loyalty and lifestyle analysis were as follows; 1) In case of males, the group of consumption-oriented type and in case of females, three groups of consumption-oriented, social-oriented and family-oriented types had great concern for brand loyalty in lifestyles and brand loyalty. 2) With relation to brand loyalty and lifestyles, thirties-aged respondents had a positive tendency to brand loyalty in consumption-oriented and social-oriented types, but forties-aged ones had a positive tendency to brand loyalty in consumption-oriented, social-oriented and family-oriented types. 3) With relation among the academic careers, lifestyles and brand loyalty, three groups(consumption-oriented, social-oriented and family-oriented types) under high-school graduates made high response to brand loyalty, and two groups (consumption-oriented and social-oriented types) of college graduates showed something responsive to it and the consumption -oriented persons of graduate school and upward made response to brand loyalty. 4) With relation among an income, brand loyalty and lifestyles, three types(consumption-oriented, social-oriented and family-oriented types) of an income not exceeding one million and half won a month were related to brand loyalty. And two types(consumption-oriented and social-oriented types) of an income below two million won a month made high response to brand loyalty. And the consumption-oriented type of an income below three million won and more than three million and half a month made good response to brand loyalty. 5) In general relation between brand loyalty and five lifestyles, the consumption-oriented type made positive response to brand loyalty and the social-oriented type was in the second place and the family-oriented type ranked next to the social-oriented type. But the economics-oriented and conservative-oriented type were not related to brand loyalty. 6) It was found that there was a difference between brand loyalty and the same lifestyle according to individual characteristics.

We compared the reproductive performance, non-productive performance, and milk composition performance of two groups of lactating cows that were either rice straw or tall fescue. We also compared and analyzed these parameters after the first parturition during the breeding period. The calving interval, artificial insemination, and duration from calving to conception were longer in the rice straw group than in the tall fescue group. The 305-day and peak milk yields were significantly higher in the tall fescue group than in the rice straw group (p<0.01). Milk fat content was significantly higher in the tall fescue group than in the rice straw group (p<0.001), but milk protein content was the same between the feeding groups. The difference in raw milk sales income between rice straw and tall fescue groups tended to increase as the number of lactations increased, but there was no effect of reduced feed costs. Analysis of the milk production and raw milk sales income of the surveyed farms revealed that the average milk production per head was significantly (p<0.05) higher in the tall fescue group than in the rice straw group, and raw milk sales income showed a similar tendency. Overall, these results provide important details to be considered when selecting feed as a way to reduce milk production and heifer raising costs. However, there remains a need for future follow-up studies exploring the relationship between feed choice and the management of heifers.
