Objective: The purpose of this study is to determine the time evolution and distribution of cerebral apoptosis using the middle cerebral artery occlusion model in rats. Methods: A total of twenty four male rats - with 2, 3, 4, 6, 8, 12, 24 and 48 hours of middle cerebral artery occlusion respectively - were studied. The terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick-end labeling(TUNEL) method was used for the observation of the apoptotic cells. The apoptotic ratio was calculated and the distribution of apoptosis was inspected in the pyriform cortex, basal ganglia and middle cerebral artery territory cortex. The rats were divided into three groups(Group I : $2{\sim}4$ hours of occlusion, Group II : $6{\sim}$12 hours of occlusion, Group III : $24{\sim}48$ hours of occlusion). Results: In this study, the proportion of apoptosis increased with the duration of middle cerebral artery occlusion and reached a maximum after about 12 hours of middle cerebral artery occlusion. The mean values of the apoptotic ratio were $30.7{\pm}11.3%$ in group I, $60.8{\pm}2.6%$ in group II and $48.7{\pm}0.7%$ in group III. The distribution of apoptosis differed in the pyriform cortex, basal ganglia and middle cerebral artery territory cortex according to the duration of time of the middle cerebral artery occlusion. Conclusion: In the middle cerebral artery occlusion model of the rats, apoptosis is found to increase according to the occlusion time, reaching a peak after 6 hours, and the distribution of apoptosis changed from the pyriform cortex to the basal ganglia and middle cerebral artery territory cortex.

Purpose : The purpose of this study was to investigate the depression, self-efficacy, and stress level of middle-aged women and to identify the factors affecting on stress, and to provide base line data for the development of nursing intervention for stress reduction of middle-aged women. Methods : Participants were 200 middle-aged women aged 40 to 60 who live in Seoul and Gyeonggi Province. Data collection period was from March 1, 2019 to April 15. In this study, the questionnaire of life events-stress, depression scale, self-efficacy was used. Data were analyzed by average, standard deviation, minimum, maximum, correlation and regression using the SPSS Program 21.0. Results : The results of this study, the correlation between depression, self-efficacy and stress in middle-aged women, depression and self-efficacy (r=-.264, p<.001), self-efficacy and stress (r=-.279, p<.001) had a significant negative correlation, depression and stress (r=.268, p<.001) had a significant positive correlation. Depression and self-efficacy were the factors affecting the stress of middle-aged women. Depression was β =.207 (p<.001) and self-efficacy β =-.222 (p=.003). Depression had the greatest influence on stress, followed by self-efficacy. Conclusion : Middle-aged women are an important time to prepare for a successful old age. Considering that the current middle-aged women are the subjects of the future aging society, their physical, psychological, and social problems are very important in preventing the elderly problems of the aging society. Therefore, effective nursing interventions should be developed that to reduce the depression and stress in middle-aged women and to improve self-efficacy and improve the quality of life of middle-aged women.

[Purpose] The purpose of this study was to comparatively investigate the correlation among body composition, resting metabolic rate (RMR), and physical activity (PA) between young and middle-aged Korean adults. [Methods] A total of 53 [male n=23, female n=30] subjects were included in this study, among whom 34 subjects were healthy young adults [male n=18, female n=16] and 19 were middle-aged adults [male n=5, female n=14]. The body composition and RMR of all the participants were measured after overnight fasting (≥8 h). The Korean version of the WHO Global Physical Activity Questionnaire (GPAQ) was used to assess physical activity. [Results] Body composition was not significantly different between young adults and middle-aged adults. Whole-body bone mineral density and bone mineral contents (BMC) were significantly lower in middle-aged adults than in young adults. Total blood cholesterol (TC) and blood glucose levels were significantly higher in middle-aged adults (TC; 195.21 ± 43.34, glucose; 103.57 ± 12.61 mg/dL) than in young adults. RMR was significantly lower in middle-aged adults (1619.57 ± 290.28 kcal/day) than in young adults (1894.37 ± 405.00 kcal/day). In middle-aged adults physical activity (PA). PA (METs, min, EE) was inversely correlated with fat mass (FM, kg, and %) and blood triglyceride (TG) level in young adults. In middle-aged adults, PA showed a significant positive correlation with lean body mass (LBM), FM (%), and RMR. Furthermore, PA EE showed significant interrelatedness with BMC among middle-aged adults. [Conclusion] These results demonstrated that high PA levels enable LBM and RMR maintenance in middle-aged adults. Furthermore, in young adults, more PA is required to induce change in body composition.

This study examines whether reciprocity exists in intergenerational resource transfers from middle-aged children to elderly parents. Analyzing data from a sample of 1123 middle-aged adults, this study highlights the importance of reciprocity in the transfer of resources between middle-aged adults and their elderly parents. The possibility of an inheritance shows a very strong effect on care-giving to elderly parents. Furthermore, past financial transfers from parents to middle-aged children correlates strongly with financial transfers from middle-aged children to their elderly parents.

Purpose: The purpose of this study was to identify the reported factors influencing fatigue of middle aged women. Methods: Two hundred seven middle aged women between 40 and 59 years of age were recruited from five areas in Korea from March 1, 2010, to April 20, 2010. Data were collected by self-reported questionnaires. Data analysis was done using SPSS/WIN 15.0 program for descriptive statistics, Pearson correlation coefficients and stepwise multiple regression. Results: The average score of fatigue was $2.34{\pm}0.40$. There were significant differences in reported fatigue according to economic status and health status. The reported fatigue was significantly correlated with somatic attribution, psychological attribution, normalizing attribution, depression, marital adjustment, stress, and social support. The major factors that affect fatigue in middle aged women were stress, depression, and normalizing attribution, which explained 32.3% of fatigue. Conclusion: The findings can reduce the fatigue by controlling stress and depression. Additionally, this study can understand the attribution of fatigue in middle aged women. More studies are needed to identify other variables that influence on the fatigue of middle aged women.

The purpose of this research was to identify arid to compare stereotypes toward the elderly held by adolescents and middle-aged adults. Stereotypes toward the elderly were examined at two levels: to assess students′and middle-aged adults′beliefs about the traits of the elderly and to categorize the traits into stereotypes. Traits groupings were analyzed with hierarchical cluster analysis. The main results of this study were as follows: First, both adolescents and middle-aged adults believed the negative stereotypes were more characteristic of the elderly than the positive ones. Second, middle-aged adults reported more complex negative stereotype sets of the elderly than adolescents. Third, Adolescents reported even more negative physical appearance trails of elderly persons than the middle-aged. Fourth, the traits endorsed as characteristics of elderly persons were often contradictory within two age groups. For example, adolescents perceived "sacrifice" as a positive trait of the elderly, while middle-aged adults perceived it as a negative one.
