Objectives: This study examined the effects of residential proximity to adult children on the mental and physical health of middle-aged and older parents. The study also evaluated whether the parental age and gender of the adult child in closest proximity to the parent might moderate the association. Method: Data were drawn from five waves of the Korean Longitudinal Study of Aging(2006-2014). The analytic sample consisted of 7,359 parents aged 45 or older who had at least one non-coresidential adult child aged 19 or older. The analyses were conducted by estimating a series of fixed effects models while adjusting for the nested structure of the data. Results: The results showed that first, a closer distance between an adult child and the parent was generally associated with the parent experiencing a decrease in depressive symptoms. Yet, the mental health benefit was smaller for parents aged 65 years or older whose closest living adult child was a son. Second, a closer distance was observed to affect chronic illness only among middle-aged parents (aged 45 to 64). When the closest living adult child was a daughter, the middle-aged parent experienced deterioration in their chronic illness. On the other hand, the opposite pattern was observed when the closest living adult child was a son. Conclusions: The parental age and gender of the adult child in closest proximity to the parent might have varying effects on parents' health. A closer distance between an adult child and their parent has a positive impact on the mental health of the parent as a whole, whereas the effect of living closer was mixed in relation to the parental physical health.

The purpose of this study is to provide for some basic data useful to production of the apparels fit and measured well for the Chinese men. For this Purpose, Chinese adult men's body types and their changes over time which had been surveyed by preceding studies were compared by age group with those of Korean adult men which had been published in a report on National Anthropometric Survey of Korea in 1997 The results of this study can be summarized as follows; 1. As a result of comparatively analyzing the differences of body types between Chinese and Korean adult men, Chinese men have higher stature and arms, while weighing more. 2. As a result of comparatively analyzing the differences of body types between Chinese and Korean adult men by age group, it was found that the changes of body types due to aging are similar between two groups. Namely, as they become older, their vertical sizes become smaller, while their horizontal sizes become larger gradually.

This study aims to survey the satisfaction level with the fit of ready-made suits(jackets and pants) among adult males and thereby to show its differences by the age group and body type. The respondents to the questionnaire survey were 465 males, aged 20 through 59 years. The conclusions are as follows: 1. The average satisfaction level for the fit of each item ranged from 2.65 to 3.57, with the higher level found in jackets than in pants, and also in circumference parts than in length parts 2. The satisfaction level for the fit by the age of adult males showed inter-group differences in the parts of jacket length, sleeve length, shoulder width, sleeve openings, and sleeve band width for jackets; and pant length of pants. 3. The satisfaction level for the fit by the body type of adult males indicated into-group differences in chest circumference of jackets only. 4. The satisfaction level for the fit, with the exclusion of the age and body type relationship showed that adult males are affected more by the age than by the body type. 5. In the repair frequency by the item, pants(45.6%) showed a higher level than jackets(24.7%). The parts with a high repair level by the item were jacket length(8.4%) and steeve length(19.8%) for jackets; and pant length(42.4%) and waist circumference(8.4%) for pants.

The purposes of this study were to investigate bag purchasing behaviors and design preferences of male and female adult consumers, and to find the differences depending on sex and age variable. A survey was conducted on 400 male and female adults from 20s to 50s. The questionnaire consisted of bag purchase behaviors, bag design preferences, and the subjects' demographic characteristics. The data were analyzed by Cronbach's α, factor analysis, x² test and t-test using SPSS. The results were as follows. First, as bag selection criteria, four factors (practicality, symbolism, aesthetics, and economics) were derived, and adult consumers considered economics as the most important among the factors. As for purchasing information sources, three factors (media, human resources, and store) were derived, and adult consumers considered human resources and store information sources more important than media. The main motive for purchasing bags was age and damage of the owned products, and Internet shopping malls were the most common purchasing place. The average annual cost of purchasing bags was 100,000 to 300,000 won, and the frequency of purchase was about once a year. Second, as bag preference images, four factors (individual, romantic, active, and classic image) were derived, and adult consumers preferred classic images the most. The shoulder bag was the most preferred as the bag shape, and black was the most preferred bag color. For the material, natural leather was the most preferred, and for the size, medium size was the most preferred. Third, bag purchasing behaviors and design preferences showed many significant differences according to the sex and age of the consumers. Therefore, the results of this study suggests that bag companies need to establish product development and marketing strategies in consideration of differences according to the sex and age group of adult consumers.

The objective of this study is to investigate the fit preference tendency for ready-to-wears(jackets, skirts and slacks) of adult women and to find out the respective differences by the age range and the obesity level. The study method was the questionnaire survey with the subjects of 295 women of 20 up to 59 years of age. The questionnaire is composed of fit preference tendency, physical measurements, age, and occupation. For the data analysis, SPSS 18.0 program was used, and descriptive statistics, Crosstabs, ANOVA, Duncan's test, t-test and multiple regression were conducted. The findings were as follows. 1. Regarding the fit preferred for each part of jackets, skirts, and slacks, among ready-to-wears, the 'thing with some extra width' in every part was most favored, followed by the 'thing fitting perfectly.' 2. The differences were found in the fit preference tendency by the age of adult women. The fit preference tendency was higher among those in their 20's than among those of the other age range. 3. The differences were also found in the fit preference tendency by the obesity level of adult women. The fit preference tendency was high in the order of the emaciation, normalcy, and obesity types. 4. For all of three items, age and body type or body type influenced the preference by the fit level. As the age was higher and the body type was fatter, those items with some flexibility were preferred.

An increase in serum cholesterol is directly associated with high incidences of cardiovascular diseases (CVD) and atherosclerosis. Serum lipid profiles are highly dependent on dietary fatty acids and age. The purpose of this study was to examine the age-related effects of polyunsaturated/saturated fatty acid ratios and antioxidant supplementation under the control of the dietary peroxidizability index (PI) value on serum lipid profiles in rats. While the PI level of dietary fatty acids was controlled at 81.22, the P/S ratios of fatty acids were 0.38 and 4.81 (LP and HP). The diets were supplemented with a vitamin E 1000 mg/kg diet and a selenium 2.5 mg/kg diet (LPS and HPS). Female Sprague-Dawley rats ages 3 weeks (young) and 16 weeks (adult) were fed four different experimental diets for 4 weeks. The serum triglyceride concentration of LPS was significantly higher in young rats than in adult rats. The total-cholesterol concentration of LP and HPS were higher in young rats than in adult rats. The high-density lipoprotein-cholesterol (HDL-C) concentration of LP, LPS and HP was higher in adult rats than in young rats. The low-density lipoprotein-cholesterol (LDL-C) concentration was higher in young rats than in adult rats. T-C/HDL-C and LDL-C/HDL-C ratios were much higher in young rats than in adult rats. In conclusion, P/S ratios and antioxidant supplementation did not affect T-C/HDL-C and LDL-C/HDL-C ratios as risk factors of CVD in adult rats when we controlled the PI value in the diet Probably, the invisible and confounding effects of dietary PI value implicate the beneficial roles of dietary P/S ratios and antioxidants in CVD. Accordingly, controlling the dietary PI value may be advantageous to lower the risk of CVD in adult rats.

Randumly sampled out 157 extracted Korean adult teeth, aged 12 to 79 years, was applicated to estimat the age by Gustafson's method, were evaluated and analyzed in terms of phyological aging change. The results are as follows : 1. It was reconfirmed that there existed comparatively close correlationship between age and score, especially in old age. 2. Korean score had comparatively high level than those of European. 3. In the probability of age edetermination, the estimation error was the most high level in the age of 70~ with ±4.47, and next order was in the age of 10-19 with ±5.20,60-69 with ±5.8,30-39 with ±5.98,50-59 ±6.20,40-49 with ±6.72,20-29 with ±9.28.Mean value was ±8.03. 4. The regression equation is as follows. y=3.55x+8.52(r=8.75) standard deviation σ=±8.03 (y= estimated age x=score) 5. In age determination with those data, needs to estimate slightly lower than caculated age in range of 10-49, and higher in 50-70 for the real age determination.

The purpose of this study was performed to analyze the trend of bodytype change of adult males. Subjects were 1290 Korean adult males and their age range was from 19 to 54 year, ; old. 75 variables(66 variables from the direct anthropometric data and 9 variables from the multiplication method) in total were applied to analyze. The principal component analysis was applied to the data with orthogonal rotation after extraction of major factors. The high factor loading items extracted by factor analysis were analyzed for the trend of bodytype change by the age group respectively. The result of factor analysis indicated that the first factor was composed with about 30 items, girth, depth and width-measures in 4 age groups and was analysed as form factors. Especially, age-related change was caused by increase of waist girth, depth and width. The second factor was composed with about 23 items, length and height-measures in all age groups. Stature has a constant factor loading value in 4 groups. Front and back waist-height and the navel-height have the highest factor loading value. The third, fourth and fifth factors were composed with different variables among the age groups.

This study was conducted in order to determine width, length of lung by radiographic method. The measurements carried out on normal chest X-ray film of 1,036 persons who took the radiograph from the April of 1977 to the June of 1978. As a result of this study, the following conclusions were obtained: 1. In the case of male, the average width, and length of both side lung size from new birth to nineteen of age was larger than female with the exception of partly age group. 2. Lung size in average width at adult was from 27.60cm to 29.20cm and female was 25.10cm to 26.22cm. 3. The mean length of left lung at adult was from 26.32cm to 25.27cm in female. 4. The average length of right lung at adult was from 25.8cm to 28.35cm in male and female was from 24.86cm to 25.17cm. 5. It was found that lung sige in width and length was slightly increased until 39 years of age, but was trend to decrease it of lung in the age of 40 years old. 6. In the case of adult, the difference of the average length between right and left lung, the length of right lung was slightly shorter than left that.

The purpose of this study is to provide for the basic data useful to the development of the quality of brassiere featuring a good wearing feeling and an effect of reinstating and correcting breast shape. For this purpose, 220 adult women aged between 20 and 59 were sampled to survey their actual breast shapes. The results of this study can be summarized as follows; 1 According to the increase of age, the items of height were decreased and items of width, depth, circumference and length were increased, being obeser and breast point were drooped. So volume and bottom are3 of breast of 40.50′s women′s age group were larger than 20.30′s women′s age group and breast point width of 40.50′s women was being wider by increase of interior dimensions of breast. 2. The components of adult women′s breast shape can be categorized into "obesity of breast", "upper dimensions of breast and drop", "lower dimensions of breast and drop", "location of breast point and vertical size of breast", "interior dimensions of breast", "exterior dimensions of breast" Such components of breast shape very in terms of weight or apparence depending on ages. Older women tend to have more droopy and widen breasts.
