Due to aging, the physical fitness of middle-aged women decreases after menopause. This results in increased body fat and reduced lean body mass, both of which can lead to obesity. This phenomenon is accompanied by changes in hormone secretion in the body. The purpose of this study was to analyze the effects of circuit training on aging-related hormones in obese middle-aged women. The subjects were 20 obese middle-aged women. The subjects were divided into two groups: a circuit training group (n=10) and nonexercise control group (n=10). Growth hormone (GH), insulin-like growth factor-1 (IGF-1), estrogen, and DHEA-S were measured before and after the circuit training program. The circuit training group performed circuit training for 12 weeks, three times per week. Exercise intensity was increased gradually from 60% to 80% of heart rate reserve every 6 weeks. In the circuit training group, at the end of the 12-week training program, the IGF-1 levels were significantly increased compared to pre-exercise levels, and they were higher than those of the control group. GH levels were also significantly increased in the circuit training group, but the differences were not statistically significant. DHEA-S was significantly increased in the circuit training group, but the difference was not statistically significant. The results showed that circuit training improved aging-related hormones levels in obese middle-aged women.

The purpose of this study is to explore and describe the health and welfare needs experienced by old parents living with disabled adult children, and to help generate research interest and public policy attention on this critical issue. For the purpose of this study, the survey was conducted with older parents who are living with dependent adult children with physical or mental disability. Among collected data for this study, data for 105 older parents were analyzed. The results showed that older parents have suffered with care responsibilities for their disabled adult children as well as special needs resulted from their old age. And older parents have little or even nothing prepared for later life because of lifetime economic, physical and social difficulties related to their disabled children. Also these difficulties had a significant impact on their idea of health and welfare needs in later life. It showed that older parents had mainly concerned and wanted to have the direct cash benefits and medical provisions but hardly recognised the importance of other services such as leisure activities. Preliminary suggestions of this study therefore may be helpful to improve the public policy approach in order to better serve older parents with disabled adult children in the coming aging society.

The study has been performed on the improvement of bonding process and bond strength of HTPB propellant and liner using a polymeric curative. In case of liner using polymeric curative prepared from reaction of HTPB and TDI, migration of curative was decreased at bond interface. So EPDM insulation sanding and Desmodur RE coating process could be omitted in motor case preparation and bond strengths between the HTPB propellant and liner were increased. Also deterioration phenomena of bond strength could not be observed in accelerated aging test.

Purpose: The purpose of this study was to examine the effects of health promotion program on healthy aging preparation for late middle aged women. Methods: The research design was a non-equivalent control group quasi-experimental study. Participants were recruited from K and Y cities in Gyeong-nam Province from October, 2013 to January, 2014. They were 26 for the experimental group and 31 for the control group. The experimental group participated in a health promotion program for healthy aging preparation. The program consisted of education, exercise, and small group discussion over 8 weeks. Data were analyzed by Chi-square, t-test and ANCOVA, using the PASW 18.0 program. Results: There were significant improvements in aging anxiety and general self-efficacy, health promoting behaviors in the experimental group compared to those of the control group. However, there was no significant differences in attitude toward older adults between the two groups. Conclusion: The health promotion program on healthy aging preparation for late middle aged women was found to be effective in enhancing aging anxiety and self-efficacy, and health promoting behavior. Thus, the developed program is recommended for use in clinical practice as an effective nursing intervention for late middle aged women in order to keep up with their health in later life.

This study portraits the way of self-preparation for death among the elderly and examines the meaning and values attached to the elderly-care by their family and friends through the analysis of Kyung-ran Jo's novels. First, the author describes the difficulties and inner conflict of women who provide care for the elderly, especially those facing death in the near future. She also describes how the acceptance of death and self-discovery among the caregivers can be developed from the experience of long term care. These are consistent with the arguments by Ecofemnist on positive sides of providing caregiving in an aging society. In her novels, caregiving from young women is not described as the consequences of internalized gender norms of traditional Confucian culture. Rather, it is depicted as attitude toward a life in a commune where the meaning of life and death of elderly is shared between generations. In addition, struggles of the elderly figures against diseases and the process of their death provide an opportunity for young caregivers to overcome the trauma of other's death witnessed in their childhood. They lead the young caregivers to reflect themselves by raising ontologistic questions on life and death. The author shows the communication between generations presenting the self-preparation of death from the old generation undergoing irreversible aging and caregiving activities of significant others from the young generation. In doing so, the author points out the ethical grounds for diseases and death in old age given the condition of personalization of death in the modern society.

It has been reported that not only collagen but also elastin contribute to inhibit skin wrinkle formation. Ultraviolet (UV) radiation induces photo-aging on human skin. Because UV radiation increases elastase activity, it is thought that increased elastase activity could be the major reason for skin elasticity reduction and wrinkle formation by UV. In the present study to standardize elastase activity measuring system, purified elastases from porcine pancrease and human neutrophil, and cell extracts of normal human primary fibroblasts, 3T3 mouse fibroblasts, and CCD-25Sk human fibroblasts were used as various enzyme sources. Furthermore, elastase activities were compared according to concentrations of enzyme and substrate and incubation time. Phosphoramidon was used as a positive control to inhibit elastase activities of normal human primary fibroblasts and CCD-25Sk fibroblasts. However, it had no influence on the activity of porcine pancreatic elastase. Therefore, it is suggested that elastase used for testing anti-wrinkle agents should be selected carefully.

As the age increases, the oral cavity, that is, the teeth and periodontium, also begin to age, and accordingly, a preparation process is required. The preparation process is an important period for oral health management to start continuously with oral health education consisting of knowledge, attitude, and behavior from the 20s. Therefore, to design a clinical dental hygiene course for patients who visited a dental clinic in Gyeonggi-do and received continuous care in an oral health care room after treatment, we tried to analyze the data of the dental hygiene assessment. As a dental hygiene assessment tool, based on personal information and general medical history, dental visit experience, bleeding on probing(BOP), bad breath measurement, phase contrast microscopy, and O'Leary index were performed. The number of subjects who had dental visits was 75.4% and those without experience were 24.6%, and as a result of the periodontal examination, generally bleeding was found in 76.3%. In preventive oral care, the stage of dental hygiene assessment in the 20s is an important first step. From this point on, it is an important time to be systematically habituated so that you can take responsibility for your own oral condition. Therefore, in this study, the results of dental hygiene assessment through oral examinations of subjects in their 20s are derived and presented as basic data for the development of dental hygiene performance competency of dental hygienists during the clinical dental hygiene process in oral health education and oral health management.

The purpose of this study was to investigate appearance concern, attitude toward cosmetic surgery, self-esteem, quality of life, and to identify affecting factors of quality of life on elderly women. The subjects consisted of 162 elderly women in the G city. The variables were measured using questionnaires, analyzed using descriptive statistic, ${\chi}^2-test$, t-test, ANOVA, Pearson correlation coefficient, and multiple regression analysis. The appearance concern, attitude toward cosmetic surgery were not significant difference in 60s and 70s. Quality of life was significant difference in 60s and 70s. Factors influencing quality of life in 60s were self-esteem, perceived health status, and explanation of quality of life is 39.1%. In 70s were self-esteem, level of education, and explanation of quality of life is 41.7%. These results suggest that it is necessary for aging preparation education included appearance concern and should be made to develop program to improve quality of life.

This study examined life in old age and images of the aged perceived by middle-aged and old-aged generations through indepth interviews with 30 persons aged 40s through 80s residing in three areas (city or county) in capital region in Korea to use it as basic information in planning social welfare policy and reorganizing social services in response to population aging in capital region in Korea. In terms of economic life of the middle-aged and olde-aged generations perceived older people's opportunities for work were rarely given to the aged due to ageism and negative stereotypes of aging and the aged, and the aged tended to regard themselves less able or unable to work. In terms of social life of the aged both middle-aged and old-aged generations perceived that the frequency of social participation was low, and the daily life of the aged was found mostly aimless, unorganized and unplanned. In terms of psycho-social life of the aged both generations still felt that they were not alienated from the family, neighbors, and the society. In terms of social welfare services both generations thought the aged needed basic services such as income maintenance, health care, housing services, and particularly they felt lack of social services. The old-aged generation was willing to travel to the distance taking more than one hour to receive social services that they would need. Both the middle-aged and the old-aged agreed upon the necessity of preparation for old age and the benefits of earlier preparation, however, they said that they could not prepare for their old age due to lack of social programs to help preparation for old age and due to spending for rearing and education of their children. In terms of perceived life in old age both middle-aged and old-aged generations tended to be slightly positive, but the degree of positiveness differed between respondents from urban area and those from rural area regardless of generations. Images of the aged were perceived to be overwhelmingly negative while positive images were very few in number regardless of generations. This finding may suggests that negative stereotypes on aging and the aged are also prevalent in Korean society like in Western societies. Based on findings of this study some implications for social policies in response to population aging in capital region were suggested.
