The purpose of this study was to investigate the relationship between hormone replacement therapy (HRT) and periodontal disease in postmenopausal women using data from the 4th and 5th Korea National Health and Nutrition Examination Survey. A total of 5,482 postmenopausal women aged 45~75 years were included as study subjects in the final analysis. The HRT group comprised 1,035 postmenopausal women who had received HRT for at least one month, and the non-HRT group comprised 4,447 postmenopausal women who did not receive HRT. The chi-square test was used to confirm the bivariate relationship between the variables. Multinomial logistic regression analysis was used to adjust for covariance (age, education, family income, body mass index, age of menopause, alcohol, smoking, dental visit <1 per year, use of oral care products, and frequency of tooth brushing per day). After adjusting for all covariates, HRT was found to be associated with periodontal disease. In particular, the relationship between HRT and periodontal disease was more evident in older women and women younger than 45 years of menopausal age. The relationship between HRT and periodontal disease was stronger in women who brushed their teeth less than 3 times per day, women without regular oral examination, and women who did not use oral hygiene products. The results of this study confirmed the importance of actively considering hormone therapy when determining policy recommendations for postmenopausal women. Especially, health programs such as HRT, regular dental examination, and oral care are needed for older women who have undergone premature menopause.

Background: Multicultural families are constantly on the rise as marriage migrants and foreign workers increase. Multicultural families appear to record poor health levels compared to native families. As health is a social issue, children of surviving generations of multicultural families are also a growing interest. This study was conducted to confirm the effect of multicultural families and parents' educational level on the scaling experience of children. Methods: For this study, the 2016~2018 Korea Youth Risk Behavior Web-based Survey data were used. In order to make the two groups of adolescents belonging to multicultural and native families similar, a total of 5,362 people were included in the survey, consisting of 2,681 individuals each from multicultural and native families using the propensity score matching method. Logistic analysis was performed to identify factors influencing the scaling experience of adolescent children. Results: The results confirm that, even after controlling for factors such as parents' educational level, household income, and children's oral health behavior, parents' nationality appeared to have a statistically significant effect on their children's scaling experience. In addition, it was confirmed that the experience of oral health education had a significant effect. Conclusion: Cultural heterogeneity and the lack of adequate language ability of immigrants affects health behavior and medical accessibility. Therefore, children from multicultural families are more likely to be exposed to unhealthy environments compared to the children of native Korean families. Based on an understanding of the socioeconomic multicultural background of individuals, education and public policy should be prepared to improve the awareness for the need for preventive oral health and provide unhindered accessibility to dental services.

The purpose of this study was to investigate the differences in time use between Korean and American high school students. The data sources were the '2009 Time Use Survey' conducted by Korea National Statistical Office and the '2009 ATUS (American Time Use Survey)' conducted by Labor Statistics Division in the U.S.. 1,734 Korean diaries (1,311 on weekdays and 423 on Sundays) and 321 American diaries (208 on weekdays and 113 on Sundays) from high school students of 15 to 18 years of age were analyzed. Descriptive statistics and t-test were used for the statistical analysis. The time use patterns of Korean students on weekdays and Sundays were different than those of their American counterparts. On weekdays and Sundays, the sleeping time of Korean students was 2 hours less than the time of their American counterparts. Koreans studied more, nearly double the time of their American counterparts on weekdays and five times more on Sundays. The study-oriented time allocation of Korean students resulted in less leisure time than the American students. Korean students spent their leisure time of more than 30 minutes participating in social activities, media, and hobbies, and their time allocation to volunteer work and religious activities were nil. On Sundays, the time for studying by Korean students was more than five times longer than that spending by their American counterparts. Koreans used their leisure time of 6 hours and 47 minutes mainly for media, hobbies and social activities. The participation rate of volunteering by Korean students was only 0.5%, though it was 31.0% for the Americans. For a study-life balance for Korean students, it was recommended that trends toward time management and social policy should increase the time allocation to sleeping, housework, work, sports, and volunteering and decrease the time use in studying and hobbies.

This study was purposed to examine the effect of the parental care burden on the labor force participation of the middle aged and older women. For this, this study used 2,125 samples aged from 50 to 70 years old that were extracted from 1st and 2nd wave of the Korean Retirement and Income Study(KReIS). In order to examine the causal relationship between two variables, Generalized Estimating Equation(GEE) and Multi-nominal Regression analysis were performed. The results showed that there was a positive effect of the parental care burden on the labor force participation of the middle aged and older women. However, this effect was limited only to the employment to the unpaid family workers. In addition, the effect was varied according to the level of caring time to the old parents. Based on that, several policy and practical implications were suggested.

This study explored the characteristics, housing deficits and expectations for support programs of low-income renter households in housing poverty in order to provide housing policy development and improvement information. Microdata of the 2014 Korea Housing Survey was utilized as secondary data for this study. A total of 2,508,672 low-income renter households (weighted count) in the bottom 40% income ranks of entire general households living in private rental units were selected as study subjects. The major findings were as follows. (1) One point four percent of the subjects were living in non-house living quarters (e.g., shanties, vinyl greenhouses, container houses, and mud huts), 1.4% were in dosshouses, 9.9% were in basements, semi-basements or rooftop units, and 8.2% were in sub-standard units. (2) Among the households whose housing costs burdens were measurable, 75.7% were found to have housing cost burdens to pay 30% or more of their household income towards housing costs (rental costs and maintenance costs), but only 7.5% of the burdened households received a housing voucher. (3) Eighty-one percent were found to be in a housing poverty status as defined by the researcher; in addition, low-income renter households in housing poverty in Seoul tended to have a greater proportion of households headed by females, the elderly, and be persons with low-education or disabilities. (4) Households in housing poverty showed greater expectations for financial support and/or extended provisions of public rental housing than other low-income renter households.

Concerns about paid-facilities for the elderly with dementia from middle and upper class families have been discussed lately in Korea. Small-scale, home-like group homes for the elderly with dementia were developed in Sweden in the 1980, but they have not been effectively introduced in Korea where they remain a comparatively new concept. The group home, however, would provide a good alternative to Koreans who feel guilty when they have to leave their frail parents in large-scale facilities or hospitals instead of caring for them at home. The aim of this paper is, first, to define the care of the demented elderly who come from upper and middle class families in Korea and, secondly, to discuss the need for group homes to help care for them. A survey was done by questionnaire and was answered by 577 respondents who belonged to middle and upper class families living in Korea in December 2000. Methods of analysis were frequency, mean, and Chi-square. The results of this study were as follows: 1) the traditional notion that the eldest son should be burdened with the primary responsibility for a demented parent has weakened remarkably; 2) a small-scale long-term care facility was considered the most desirable living environment for the demented elderly; 3) the facilities families needed for professional hospitals for victims of dementia, senior citizen centers, large and small-scale long-term care facilities, day-care centers, and short-stay and service housing. The study also revealed that there was low awareness of the group home. The most preferred type of structure for group homes was a single-family detached house, and the most preferred management system was small-scale that could create home-like atmosphere. Additionally the respondents wanted group homes to consist of 6-8 residents with 2-4 persons per room. The results of this study strongly suggest that policy makers should encourage the development of smallscale group homes as an alternative form of housing for the elderly with dementia.

The purpose of this study was to evaluate the dietary attitude and food behavior of elementary, middle and high school students in Korea. The subjects in this study were 7,698 boys and girls in large cities in Korea. The questionnaire was made and distributed to the students to answer the questions. Followings are the results of this study : 1) Father and mother's average ages were 45 and 41 years old, respectively. 2) Most students thought dietary life was more important than clothing or residentary life. Dietary habits such as irregularity of meal, frequencies of skipping meal and of eating out increased in higher grade than in lower grade, and in girls than in boys. 3) Most students, especially in elementary school, recognized that their own bad dietary habbit was unbalanced diet. Irregular meal time and eating too much were also pointed out as problems by middle and high school students. 4) Most students thought that the most effective meal for health was breakfast, but they replied the tartest meal as dinner. 5) Students tended to prefer Korean style food. Cooked rice and kimchi, ramyun, and pizza were ranked the most preferred food when they were hungry. 6) Elementary school students ate meals more regularly than higher grade students, and girls ate meals more regularly than boys. 7) Skipping rate of breakfast was higher than that of lunch or dinner, and the percentage of meal skipping students was increasing with grade elevation. No time to eat or eating between meals was the reasons of irregular meal time. 8) Frequency of dining with family was decreased, but frequency of eating out with friends was increased with increasing grade. The gravity of dining out is increasing rapidly in Korean adolescents. Therefore, nationwide nutrition education policy is necessary to constitute a right dietary environment and a desirable dietary altitude.

In this paper, the possibility and necessity of the digital broadcasting propulsion in AM and FM is presented based on DRM and DRM+ transmission modes, They are the members of series technological family in digital radio development. As the frequency utilization, the application of DRM+ is flexible in any mode such as IN-BAND or OUT-OF-BAND. When the digital audio broadcasting is planned at LOW-VHF bandwidth such as TV channel No.5 and NO.6 being adjacent to FM band and OUT-Of-BAND DRM+ technology is applied, there is no collision and jamming. Particularly, in the IN-BAND Hybrid mode, it is mentioned that there was the difficulty problem for multiple SFN transmitters uses. Not like the IN-BAND mode the OUT-OF-BAND mode lets multiple transmitters, because neighbor transmitters do not interfere each other. Digital transmitter can be combined with the existing FM transmitter. The intensity of power and size of area can be easily determined according to local broadcasters' condition. And the OUT-OF-BAND mode is advantageous for AM/FM integration in digital radio receiver manufacturing, which makes the conversion schedule much shorter.

This study investigates whether earnings management behavior of chaebol firms differ from that of non-chaebol firms. The ownership structure of chaebol firms is characterized by the dominance of one largest shareholder and his family members who typically participate in the management of the firm directly or indirectly and influence most of the important management decision. This study adopts the random effect model and the hausman and talyor model, using a panel of 5092 firm-year over a period from 1991 to 2010 to control for potential heterogeneity and endogeneity that may cause sever bias. This study finds that there is no difference in accrual based earnings management level between chaebol firms and non-chaebol firms. However, chaebol firms appeared to engage less real earnings management that is known to negatively affect future earnings and share prices. The results are consistent when controlling for potential heterogeneity and endogeneity in the hausman and taylor model. The results may be of interest to various stakeholders, policy makers, standard setters and academic researchers.

This study aims to verify the effect of the rural community living home use through an analysis of depression among the elderly women who live alone in the rural community living home. A survey was conducted from July to September 2015 through direct interviews with 236 elderly people who live alone in community living homes at 52 locations across the country. The main results of this study are as follows. First, social support from family/relatives and neighbors/friends was found not to affect depression in the elderly living in community living homes. Second, satisfaction with health status, economic status and life appeared to affect their depression. This indicates the need for various measures to increase the subjective satisfaction of health. Third, when the demographic characteristics, social support and personal satisfaction were controlled, the period of use, satisfaction with use and operational service/no service were proven to have an impact on depression in the elderly living alone in community living homes. In other words, since the level of satisfaction with community living homes is very high and this has a positive impact on the elderly living in community living homes, it is desirable to have an ongoing policy for the homes to be utilized as important welfare resources. Based on these findings, this study proposes improvements in the user experience and programs and services offered for rural community living home business programs.
