Objectives : School-age children have mixed dentition and are sensitive to dental caries. Their dental condition is more important as it is directly related with oral health in their life, and parents' attention and education are necessary as the children can not manage their oral health voluntarily. Methods : To evaluate the effect of parents' occupational status on the oral health of children, this study conducted a questionnaire survey and analyzed the results along with the results of oral examination with 952 students and their parents of an elementary school located in Ulsan conducting school oral health projects on May, 2009. Results : As dental caries prevalence rate recorded 33.7%, 56.8% and 66.9% in non-dual income, professional dual income and non-professional dual income families, respectively, the rate of children of dual income families was significantly higher than that of non-dual income ones (p<0.05). Conclusions : For professional dual income families, although working mothers contribute to economic stability, they took less time to care or to educate their children compared to no-working mothers so that they need to pay more attention to oral health of children. In addition, more interest to and education for children of non-professional dual income families showing relatively lower socio-economic level and lack of time for children, were also necessary in school projects on oral health education and prevention.

The purpose of this study is to investigate the effects of wife's employment status on the household expenditures of timesaving market substitutes for houseworks. Seven expenditure categories were considered such as food away from home, convenient/prepared food, housing care service, clothing care service, childcare, supplemental education, and domestic services. The data were taken from 1999 Family Expenditure Survey by National Statistical Office. The sample consisted of 29,963 households with 33.2% dual-income households. The average monthly expenditure for food away from home was 127,795 won for dual-income households, while 103.100 won for single-income households. The expenditure for childcare of dual-income households was over six times of single-income households'. Dual-income households spent over ten times of single-income households for domestic services. For most expenditure categories, households with wife working at white-color jobs spent more than other dual-income households. After being other household characteristics to be constant, wife's occupation had found to be related with the household expenditures for most market substitutes. For the expenditures on both food away from home and childcare, employed-wife households with any kind of jobs were found to have higher possibility to spend and to be spent more than non-employed-wife households. The households with wife employed at white-color jobs spent more on clothing care service and domestic services than the households with the not working. Employed-wife households had higher possibility to spend on supplemental education, but they did not spend more on the expenditure, compared to nonemployed-wife households.

The purpose of this research is to compare housing wealth effects of home-owning single income couples (SIC) and dual income couples (DIC) on their non-durable consumption and to assess the effects by location, age groups, housing structure type, debt-to-asset ratio and employment status. Using the Korean Labor and Income Panel Study (KLIPS) of 2014, this empirical study identified 1,198 SIC households and 1,044 DIC households, and employed multiple regression analysis. The main results reveal that the difference of financial portfolios between SIC and DIC households was little but housing wealth effects were stronger among SIC households than DIC counterpart. It's evident that housing wealth effects were conspicuous for SIC and DIC households who were headed by wage earners aged over 40s, and resided in apartment outside the Seoul Metropolitan Area. However, household debt became a determinant in contradicting housing wealth effects of SIC and DIC households. While the household financial dimension was in proportion to income, DIC households didn't gain much financial security due to increasing expenditure. Further, this research imply that liquidity constraints explicitly posed a more serious threat to SIC households whose dependence on housing asset is larger than their counterpart.

This study analyzes diverse factors in time poverty and quality of life in dual-earner families with preschool children that pertain to the individual, family, and occupation. Data were taken from the 17th edition of the Korean Labor and Income Panel Study developed by the Korea Labor Institute in 2014. The sample consists of 826 households who are dual-earner families with preschool children. The major findings are as follows. First, this study identified inadequacies in personal care time for dual-earner families with preschool children. Second, the results show that gender, recognition of gender role, and overall satisfaction of occupation are related to the time poverty of dual-earner families. Men are more likely to experience time poverty than women, and equal recognition of gender role and satisfaction of occupation indicate a negative relation on the time poverty of dual-earner families with preschool children. Last, quality of life in non-time-poor groups is higher than for groups who experience time poverty. Also, health state, earned income, work-family life conflict, and overall satisfaction of occupation are commonly related to quality of life in both groups. The results suggest implications for comprehensive policies to address family time issues.

The study explored the work-life balance of three dual-earning couples using the household economics approach according to the hermeneutics paradigm. Three families were analysed. The couples were interviewed individually with a non-structural interview guide about their work history and life history, and with a semi-structured interview and structured questionnaire about their work hours, childcare practice, husband-wife relation, household income and expenditure, and daily and weekly schedule. The results revealed the different paths and various strategies to adjust work-life balance among the cases. Strategies were discussed to facilitate changes in labor market policy, childcare policy, working place culture and family's daily life planning.

This study identifies the relation between recognition relatively deprivation and consumption patterns. The data used were the seventh Korea Welfare Panel Study (KOWEPS). The final sample of 1,597 households was selected based on several sampling steps standard weights suggested by KOWEPS were applied. The final sample was subdivided into household recognizing relatively deprivation (51.7%) and non-household recognizing relatively deprivation (48.3%) per level of subjective income and objective income. We derived six consumption patterns from the cluster analysis as per consumption ratio: transportation dominant consumption pattern, essential consumption pattern, other dominant consumption pattern, care attention consumption pattern, private transfer consumption pattern, and education dominant consumption pattern. The results of this study are as follows. The analysis of the determinants of recognizing relatively deprivation in regards to question one found that the household was likely to be relatively deprived when: the head of a household was older, a household had a dual income, children and more total assets then those assessed 1 year ago compared to household living conditions, result of comparing the consumption patterns difference between household recognizing relatively deprivation and non-household recognizing relatively deprivation indicated that household recognizing relatively deprivation was more likely to belong to the transportation dominant consumption pattern, other dominant consumption pattern, and private transfer consumption pattern. The multinomial logistic analysis conducted to understand the determinants affecting the consumption patterns of household recognizing relatively deprivation indicated differences in demographic characteristics, household-related variables, financial variables and perception of economic conditions.

This research aims to investigate the socio-demographic, financial, and housing statuses of young married couples in Chonsei housing and to analyze the determinants of their residential environment quality and housing expenditure in four districts - Seoul and Gyeonggi-Incheon Area(GIA) of the Seoul Metropolitan Area(SMA), and metropolises and non-metropolises of non-SMA. From the 2020 Korean Housing Survey(KHS), this cross-sectional analysis examined a sample of 691 households, and the findings revealed that most were headed by college-educated, salaried male workers aged 31 years old. While childless dual-earner couples were common in Seoul, single-income families of three were prevalent in non-SMA. The financial status of the couples in Seoul was a lot better than in the other three areas, particularly much higher in Chonsei deposit and total asset value. Further, many lived in a three-bedroom apartment unit sized 60m² and bigger, using a Chonsei loan. Regardless of areas, almost all the households spent a very low portion of their living expenses and income on housing costs. However, dual-earner families positively increased borrowing capacity, which improves the household's financial position that is likely to lead to equity increment in a volatile asset market in the long run. The statistical results indicated that residential environment assessment was influenced by neighborhood quality and housing expenditure was affected by housing size in Seoul, urban amenities in GIA and householder's gender in non-metropolises. Thus, this research proposes that strong measures be considered to mitigate housing inequality embedded in geographical and socio-economic disparities.

This study was performed to investigate the relationships among bone mineral densities (BMD), anthropometric data and lifestyle factors in the elderly. Subjects included 138 elderly (male: 38, female: 100) aged over 65 years, who were home-(dwelling in a low-income area of Puchon City. The BMDs of the lumbar spines (LS), femoral necks (FN), Ward′s triangles (WT) and trochanters (TC) were measured by dual energy X-ray absorptiometry. The females showed significantly lower BMDs in four sites (p < 0.0001) . The elderly aged over 75 revealed significantly more decreased femoral BMDs than the elderly aged 65 to 74. Female with BMIs of 20 to 25, showed significantly higher BMDs in LS, FN and trochanter than those with BMIs of less than 20. However, males displayed significantly higher BMDs in only LS with increasing BMIs. THe BMDs of LS correlated with weights (r = 0.543, p < 0.001), heights (r = 0.477, p < 0.001), upper arm circumferences (r=0.368, p < 0.01), waist circumferences (r=0.367, p < 0.001), subscapular skinfold thicknesses (r=0.363, p < 0.001) and flip circumferences (r=0.231, p < 0.01). Non-smokers and non-drinkers shelved significantly higher BMDs in trochanters only in the case of the males. Female milk-drinkers showed significantly elevated LS BMDs. Eighteen percent of the males were assessed as having osteoporosis, as compared to fifty percent of the females. Ninety-three percent of the females and 81.6% of the males responded that they often or always had "difficulty in standing for a long time".

Objective: The goal of this study were (1) to examine the type of parental time, (2) to investigate the family's characteristics that affect the parental time types. (3), to identify the differences in time satisfaction and time deficit according to the types of parental time of mothers with preschool children. Methods: The data source for this research was the 2014 Time Use Survey conducted by the Korea National Statistical Office(391 time diaries). Data were analyzed using K-means cluster analysis, multinominal regression, and ANOVA. Results: The results can be summarized as follows. First, parental time was classified into four groups; non-participation, play-centered, physical care-centered, unspecified group. Second, the characteristics of each type depended on children's age, mother's education level, mother's income, and dual earner families. Third, time deficit showed significant differences between play-centered and non-participation type. Conclusion/Implications: Based on the results, implications for policy regarding child care and labor were suggested.

Background: Identifying and managing osteoporosis among cancer survivors is an important issue, yet little is known about the bone health of cancer survivors in Korea. This study was designed to measure the prevalence of osteoporosis and to assess related factors among Korean cancer survivors. Materials and Methods: This study was designed as a cross-sectional analysis. Data were obtained from dual energy X-ray absorptiometry measurement of the lumbar vertebrae and femoral neck, and from standardized questionnaires among 556 cancer survivors and 17,623 non-cancer controls who participated in the Fourth and Fifth Korea National Health and Nutrition Examination Surveys (2008-2011). We calculated adjusted proportions of osteoporosis in non-cancer controls vs. cancer survivors, and we performed multivariate logistic regression analysis. Results: The prevalence of osteoporosis among cancer survivors was significant higher than that of the non-cancer controls after adjusting for related factors. Furthermore, osteoporosis among cancer survivors was higher in elderly subjects (60-69 years : adjusted odds ratio (aOR) 3.04, 95% CI : 1.16-8.00, ${\geq}70$ years : aOR 6.60, 95% CI 2.20-19.79), in female cancer survivors (aOR: 7.03, 95% CI: 1.88-26.28), and in a group with lower monthly income (aOR: 3.38, 95% CI: 1.31-8.71). In male cancer survivors, underweight and lower calcium intake were risk factors. Conclusions: These data suggest that the osteoporosis among cancer survivors varies according to non-oncologic and oncologic factors. Effective screening should be applied, and a sufficient and comprehensive management should be matched to individual cancer survivors early after cancer treatment.
