The Purpose of this study was to explore the effects of differentiation, emotion over involvement(expressed emotion), and criticism between middle-or-old aged parent and child, by relation of emotional system, on child's psychological depression. The subject of this study were m premarital adult children over 30 years old. The major findings of this study were as follows. First. it was found that mother-child differentiation was more perceptive than that of father-child. With psychological depression, expressed emotion within family and criticism were shown average score that was lower than middle score. Second, among demographic characteristics, there are significant differences premarital adult children's sex, education, income, family type, father's education, and parents' marital status. Third, as the result of regression analysis, the higher level of psychological depression when the lower differentiation between parent-child, the higher expressed emotion over involvement within family and criticism. Based on the findings in this study, the relation of emotional system is very important. Therefore, it is necessary to consider the therapeutic intervention and relation improvement program when individual and family counseling about parent-child are going on.

When it is necessary to wear masks for long periods, such as during the current COVID-19 pandemic, the essential function of masks to prevent contamination (or transmission to others) as well as comfortableness are important. For this study, we used three-dimensional (3D) facial measurements of adult women to compile basic face shape data for designing comfortable and effective masks. This study analyzed the 3D facial data of 127 subjects in their 20s to 30s of the 6th Size Korea. Factor analysis of the survey data produced seven factors that formed the composition of adult female faces. These factors combined to produce three facial types: square (long face and a large lower middle face), oval (smallest central and lower body in the middle), and triangle (short face with a small central and lower large nose). These types reflect that the facial types of adult women show the differences in the nose angle, nose length, bitragion-subnasal arc, bitragion-menton arc. Therefore, properly fitting masks for fine dust particle filtration require 3D customization of a mask's breathing apparatus to fit differently shaped central and lower face parts that interfere with mask fit.

The purpose of this study was to investigate mediating the effect of Happiness Enhancing Activities(HEA) on the relationship between Balanced Time Perspective(BTP) and Subjective Well-Being(SWB). For this study, total subjects were 372 which is composed of the early-aged adults 192 and late middle aged adults 180 from Busan and Gyeongsangnam-do in South Korea. They completed the survey which is included Zimbardo Time Perspective Inventory(ZTPI), Korean Version of the Happiness-Enhancing Activities Questionnaire(K-HAQ) and Satisfaction with Life Scale(SWLS), Positive and Negative Affect Scale(PANAS). As a result of bootstrapping, BTP has a positive effect on SWB with the mediating effect of HEA and it comes out in the both subjects, early-aged adults and late middle-aged adults. To be specific, mediating effect of goal-focused activities and activities with family and friends in the relationship on BTP and SWB was significant for the early-aged. However only mediating effect of activities with friends in the relationship on BTP and SWB was significant for the middle-aged. This study is meaningful, it has turned up the effect of BTP on HEA in both subjects, early-aged adults and late middle-aged adults as well as found out the differences between generations of HEA.

Purpose: The purpose of this study was to identify and compare the factors influencing attitude toward one's own aging among Korean middle-aged adults and the elderly. Methods: A cross sectional study was performed with a total sample of 70 middle-aged adults and 64 elderly reside in two metropolitan areas. Data were collected from August 2015 to November 2015 using the Perceived Health Status Scale, the Health Locus of Control Scale and the Attitude Toward own Aging (ATOA) Scale. The statistics used include percentage, t-test, Pearson's correlation coefficient, and multiple regression. Results: Mean age for each age group were about 52 and 76 years old for middle-aged adults and the elderly respectively. A considerable proportion of all participants reported a negative attitude toward aging. Perceived health status was the common factor influencing attitude toward one's own aging in both age groups. Middle-aged adults identified presence of chronic illness and internal health locus of control as important factors. In contrast, the elderly reported that education and others-dependent health locus of control such as powerful others had a significant impact on ATOA. Each regression model explained 31% and 55% of the total variance of ATOA among middle-aged adults and among the elderly. Conclusion: Both middle-aged adults and the elderly with low perceived health status are at risk of negative ATOA's. The type health locus of control need to be identified and utilized based on individuals' tendency to improve positive ATOA. That is, middle-aged adults might need reinforcement of their self-will whereas the elderly might need enhancement of social support and network of family and healthcare providers.

Purpose: The purpose of this study was to evaluate the influence of the Koryo Hand Acupuncture Therapy on middle-age women s obesity index. Methods: A total of 38 middle-age women were assigned to either a control or an intervention group. The intervention group received Koryo Hand Acupuncture Therapy three times a week for ten weeks. The two sample t-test was used to compare the body mass index, fat mass, and waist-to-hip ratio between the intervention (n=18) and the control group (n=20). Results: In both groups, body mass index did not change significantly following the intervention. The intervention group lost $1.00{\pm}1.10kg$ of fat mass (p=.00) and the decrease was significant between the intervention and control group (p=.00). Both groups had increase in waist-to-hip ratio, however, the increase was only significant for the control group (p=.00). Conclusion: The application of Koryo Hand Acupuncture Therapy influenced the change of fat mass, but not clinically significant. It may be useful to repeat the study and to examine other factors that may have interfered with the effectiveness of the intervention. The use of Koryo hand acupuncture therapy should be further studied.

Purpose: this study was to develop and test the structural model that explains husband and wife compatibility and family health of married middle-aged. A hypothetical model explaining husband and wife compatibility and family health based on literature reviews. There were three theoretical variables and twelve observed variables in hypothetical model. Methods: Data collection was carried out May through July 2005. Data were collected by self-reporting questionnaires from 854 married middle-aged who lived in Seoul, Busan, Daegu, Kyungnam, Kyungpook. Collected data was analyzed using SPSS/WIN 12.0 for descriptive statistics, Pearson Correlation coefficient, and Kolmogorov-Smirnov analysis. Results: LISREL program was used to find the best fit normal which assumes causal relationship among variables. This model was to be good fitting and parsimonious to measure husband and wife compatibility and family health of married middle-aged. Conclusion: Differentiation of self and husband and wife compatibility predicted level of family health. Therefore, a family health improvement program needs to include these two variables.

Selenium is a strong antioxidant trace mineral, scavenging free radicals. The prevalence of chronic degenerative diseases is increasing in Korean adults with increasing age. The increased cell damage from free radicals has been implicated in the etiology of these diseases, and evidence is accumulating that the low selenium status that comes with advanced aged is involved in the prevalence of age-associated diseases. However, little is known about the selenium status of Koreans, its age-related change and its relationship to dietary nutrient intake. In this study, the serum selenium levels of healthy adult females according to life cycle and its association with blood albumin levels and nutrient intake were examined. Serum selenium level was measured with the Huwo research reactor using the neutron activation analysis method (NAA). The overall proportion of women with selenium deficiency, serum selenium concentrations below 7.0 $\mu\textrm{g}$/dl, was 9.4%. The average serum selenium levels were 12.39 $\mu\textrm{g}$/dl, 9.45 $\mu\textrm{g}$/dl and 9.16 $\mu\textrm{g}$/dl in the young adult, middle-aged and elderly groups, respectively, showing a reduction of selenium status with advancing age. Selenium deficiency was seen only in the elderly group. Generally, serum selenium levels positively or negatively correlated with nutrient intake, but these association patterns differed depending on the age. The nutrients that showed positive correlations with selenium levels were proteins and phosphate in the young adult group (p < 0.05, p < 0.05), and total calcium, potassium and vegetable-origin calcium in the middle-aged group. Vitamin C and fiber were the negative correlated nutrients with serum selenium levels in the elderly group (p < 0.05, p < 0.05). Multiple stepwise regression analysis of the determining factors responsible for selenium status showed that age and serum albumin levels were important factors which explained up to 26.9% variances in serum selenium levels. The average selenium concentrations of Korean adult female subjects were above the deficiency levels in all three age groups. There was a tendency toward decreasing selenium levels as the age of the subjects increased. The factors with the strongest in-fluence on selenium status in healthy adult Korean females were age and serum protein status. (Korean J Nutrition 36(5): 491~499, 2003)

Objectives: Purpose of this study is to analyze and to estimate which and how much genetic and environmental factors have affected on growth. Also, a method of final height prediction can be developed from this study results. Methods: Correlation analysis and categorical regression analysis were conducted between genetic and environmental factors correlated with the final adult height, through survey from 171 male. Results: Mid parental height, neonatal body weight, intake frequency of beef, chicken, milk, fruits and coffee, sleep quantity and quality during the elementary school and sleep quantity during the middle school have affected on the final adult height. And a regression equation with 0.494 for coefficient of determination was obtained. Conclusions: Mid-parental-height has the most affected on the final adult height. Among environmental factors, food and sleep have significantly affected, but exercise doesn't. Among foods, meal, beef, and milk intake have remarkably affected on the final height, and chicken and fruit also have affected in some degree, but coffee has affected badly. Among sleep habits, sleep quantity during the elementary school has the most affected, sleep quality during the elementary school and sleep quantity during the middle school also have affected in some degree on final height. The younger the age is, the more sleep have affected and sleep quantity have more affected than sleep quality. Neonatal weight also has remarkably affected on the final height. Through this analysis, the final adult height can be predicted using regression equation which covers 49.4% of genetic and environmental factors.

Purpose: This study examined the characteristics differences associated with 1-year continuous smoking abstinence in Korean young adult and middle-aged male workers. Methods: 'Korea National Health and Nutrition Examination Survey (KNHANES)' is an ongoing surveillance system that assesses the health and nutritional status of Koreans. For a secondary analysis of cross-sectional data from KNHANES VI-1, this study selected 683 Korean male workers as a subpopulation, who were young adult or middle-aged. The subpopulation was composed of success or failure group of 1-year continuous smoking abstinence. Binomial logistic regression analysis was performed. Results: Success group was more likely to be older, live in urban areas, rate their health status as excellent or good, and have ever been diagnosed with hypertension than failure group. Additionally, Success group was less likely to have used electronic cigarettes (e-cigarettes), drink more than once a month, and have been exposed to secondhand smoking in workplace within a week. Conclusion: Developing smoking cessation programs requires consideration of resources in rural areas, promoting self-efficacy, restricting e-cigarettes and drinking, and promoting a smoke-free workplace.

This study aims to examine the patterns of middle-aged parents' intergenerational support exchange with their adult children and its effects on the happiness of the parents. The sample consisted of 765 middle-aged parents selected from the National Survey of Korean Families by the Ministry of Equality and Family in 2010. The results were as follows. First, intergenerational support exchange between parents and their adult children was categorized into four groups depending on the provider of support: parents who exchanged no support with their children, parents who only received support from their children, parents who only provided support to their children, and parents who exchanged support with their children. Second, parents who exchanged no support with their children were high in instrumental support and those who both provided and received support were high in emotional support. Third, consciousness of their children significantly affected the satisfaction level of their relationship with their children. The more the parents emphasize on the growth of their children, the more they were satisfied. Parents in the support exchange group were more satisfied when they received economic support from their children. With regard to instrumental and emotional support, parents were more satisfied when they provided support to or mutually exchanged support with their children. Forth, subjective health conditions, consciousness of their children, and household's income more significantly affected the happiness of middle-aged parents than the patterns of intergenerational support exchange. With regard to economic support, parents who only received support from their children were less happy than the other groups. With regard to instrumental support, parents who exchanged no support with their children were happier than the other groups. With regard to emotional support, parents who provided support to their children were happier than the other groups.
