This study was designed to find out the effects of aerobic exercise on the serum lipids in the middle-aged women. The effects of aerobic dancing on serum total cholesterol(TC), triglyceride(TG) and HDL-cholesterol (HDL-C) were studied in eight sedentary women(control group) and twenty seven aerobic exercising women(aerobic group) , aged 35∼45%. Aerobic exercising subjects were divided into 3 group; 2 to 3 months exercising group(Al), 4 to 10 months exercising group(AH), over 1 year exercising group(AIII) according to the periods of exercise. The serum lipid levels of aerobic exercising groups(AI, AII, AIIII) were compared with those of control group. The results statistically analyzed were summarized as follows : 1) The serum TG levels of aerobic groups decreased very significantly compared with those of control group(p< 0.001) and tended to be lower with the increase in aerobic periods. But there were no significant differences among aerobic groups by ANOVA. 2) The serum TC levels of aerobic groups decreased compared with those of control group and tended to be lower with the increase of aerobic periods. But there were no significant differences among groups. 3) Serum HDL-cholestrol level of A I group was elevated significantly compared with that of control group and significant difference was observed according to the aerobic periods : AR group exhibited higher serum HDL-cholesterol values than AH group, and AH group higher than A I group.

Objective: The aims of this study were to assess the direction and degree of lip-line cant in Korean adult orthodontic patients and to identify the effects of sex and age on changes in the cant severity. Methods: In this cross-sectional retrospective study, lip-line cant was measured in the frontal photographs of 585 Korean patients (92 men and 493 women) aged 18-48 years. The outcome variables (direction and degree of lip-line cant) were assessed in terms of predictor variables (sex, age, sagittal skeletal relationship, and menton deviation angle). Results: The direction of lip-line cant did not differ according to sex, age, or skeletal classification. Patients had $1.6^{\circ}$ of lip-line cant on average before orthodontic treatment. Middle-aged adults displayed a significant trend toward a lower degree of lip-line cant compared to younger adults (p < 0.01). Multiple linear regression analysis showed that the degree of lip-line cant was weakly negatively correlated with age (p < 0.001). Conclusions: While the direction of lip-line cant did not differ according to the parameters explored here, the degree of cant was correlated with age in adults, independent of menton deviation. Specifically, middle-aged adults tended to display significantly lower degrees of lip-line cant than did younger adults.

The Purpose of this study was to examine the environmental characteristics of housing for the elderly preferred by the middle aged. The residential environments include three types of elderly housing differred in the availability of care service as well as indoor and outdoor environmental characteristics of the housing. The results of this study were as follows: The most preferred type of the elderly was the elderly housing with no care service followed by the housing with intermediated care service and dependent housing with full care service. The preferred type of housing for the elderly was significantly related to the demands for the demands for the indoor and outdoor environmental characteristics of the comimg elderly.

This study has used the Korean Retirement and Income Study 5th Additional Data of National Pension Research Center and adopted 7,763 people aged 50 or older as research subjects. Research into correlation between social support and ways of coping stress among these subjects have revealed that the higher the social support is, the more frequently they use active coping, passive coping, and social support coping and that the lower the social support is, the more frequently they use evasive coping.

The study attempts to examine the moderating effects of social support and self-complexity in coping to the death of spouse among middle and old-aged widows. The important findings from the data based on the sample of 161 widows are (1) age differentiates the types of stress experienced by widows (2) social support and self-complexity may either buffer or intensify depending on the circumstances in which widows reside in the negative effects of stress on psychological health among widows and (3) the moderating role of social support and self-complexity differs according to age of widows with older widows being more affected by these coping resources The results of the study support the assumptions drawn from Life-Course Perspective to explain the coping process to the death of spouse.

The effect of motion taping on the grasping power of the wrist is investigated and here Based on the data obtained from the This study was conducted to provide a theoretical background for the study. Motion taping was performed on the wrist for middle-aged people between 50s and 60s, and the change in wrist gripping power through an electronic dynamometer was tested. According to the wrist grip test results, it was investigated that the application of motion taping has a great effect on the gripping power of the wrist. It is hoped that motion taping will be a tool to reduce musculoskeletal industrial accidents, and it will be helpful to improve the quality of life of workers by reducing the labor intensity or softening the wrist through motion taping.

Ergonomic vehicle design is very important for driver's safety and sensibility. Many studies have emphasized the physical factors of human operator and usability of control devices. However, driver's cognitive factors such as the shape of cognitive map have not been well documented. The aim of this research is to find the relationship between the shape of Instrument Pane (IP) in driver's cognitive map and the real vehicle. To do this, Sketch Map Method (SMM), that is an extraction method of cognitive map, was employed to extract the shape of middle-aged driver's cognitive map. In this study, SMM was modified to formulate driver's cognitive map because this process is not being in the existing SMM. Next, correlation was analyzed between individual cognitive map and the shape of real vehicle's IP. The result showed that the position of volume control switch and cigar jack was similar between these but the position of others wasn't.

The youth-pursing syndrome is especially amplified through a variety of media due to medical technology development, increases in social activities, and influence. This study discusses the relationship of youth-pursuing, media appearance information interest, and media contact responses focused middle-aged women. Data were collected from 245 females aged 40-65 in Seoul, Daejeon and Chungbuk area residents. The SPSS WIN 21.0 program analyzed the data by descriptive statistics, factor analysis, and regression analysis. Youth-pursuing derived social, psychological, and outward factors. Only an outward factor of these three dimensions influenced a significant media appearance information interest, and media contact response. The regression analysis results for chronological age and cognitive age, cognitive age influenced all variables significantly (three factors of youth-pursuing, media appearance information interest, and media contact response). But chronological age influenced significantly only the media appearance information interest. This study verified the relationship of youth-pursuing and media variables (media appearance information interest and media contact response).
