The present study investigated the related variables of cognitive function, subjective cognitive decline and cognitive training effects. The cognitive training was composed of mete-cognitive education and cognitive task performing. Twenty older adults attended for 14 weeks and were tested before and after the training. Results show that their cognitive level was related with age, self-esteem and personality traits. And subjective cognitive decline was related depression, anxiety, personality traits, self-efficacy, self-esteem and subjective age, but it does not reflect objective cognitive impairments. Their cognitive test scores were enhanced after training in MMSE, memory and executive function, and enhanced scores were related with age, subjective cognitive decline, anxiety, self-efficacy, self-esteem, subjective age and personality traits. Findings suggest one's personality and psychological state need to be considered for the effects of cognitive training.

The purpose of this study is to understand the effect of psychosocial support, death preparedness, and ego integrity on death anxiety in old people. The participant of this study were the elderly who attended welfare centers, worked in their workplaces, or lived at their home in Seoul regions, from whom this study had collected their data from February to May 2017. A total of 350 questionnaires were distributed and 329 copies of them were used for its final analysis using SPSS 24.0 and AMOS 20.0 statistical programs. According to the results of this study, psychosocial support had no statistically significant effect on death anxiety, whereas death preparedness and ego integrity had statistically significant effects on death anxiety. Based upon these research results, this study suggested that it is necessary to develop death education and counseling programs as policy supports and practical methods for helping old people to accept their death positively, reintegrate their ego, and perform their successful aging.

The purpose of this study is to explore the lived experience of aging of the poor elderly and to identify suitable welfare policies on their behalf. For this purpose, I selected 16 participants from the criterion sampling of the impoverished elderly and conducted in-depth interviews, after which the collected data was analyzed using the phenomenological approach of Cloaizzi(1978). As a result, 27 themes, 10 clusters of themes, and 4 categories were pinpointed. The 4 categories are 'Facing death,' 'Becoming despondent in heart and mind,' 'Living a hard life,' and 'Going with the flow of life.' By integrating the meanings of these findings, the essence of the lived experience of aging of the poor elderly was to be, 'Self-sufficiency despite receiving welfare benefits from the government.' The lived experience of aging of the poor elderly was revealed as not being entirely based around dependency but rather around strongly independent and positive life attitudes. But also found were difficulties due to lack of living expenses required for survival, deep death anxieties, and life attitudes in the context of Confucian culture. Based on the study results above, I presented welfare policies for the poor elderly as outlined: implementation of social activities in order to encourage independence and positivity among the poor elderly, actualization of payment that meets at least the minimum costs of living, consolidation of psychological-emotional assistance, implementation of death-related education programs, and the compilation of a welfare policy manual for the impoverished elderly.

This study examines the relationship between retirement preparation, positive psychological capital and successful aging for retirees and retirees, promotes successful aging of retirees and retirees, and increases positive psychological capital to increase desirable retirement time. I want to find a direction I can have. This study was conducted on 537 retirees and retirees who were preparing for retirement or retired from across the country as a structural relationship analysis, and the data collection period was from April 1 to April 20, 2019. As for the data, frequency analysis, correlation analysis, and structural relationship analysis were performed using SPSS 20.0 and AMOS 9.0. As a result of the study, retirement preparation of retirees and retirees had a negative relationship with successful aging, and retirement readiness had a positive effect on self-acceptance of successful aging and autonomous life as mediators of resilience of positive psychological capital and self-efficacy. This means that the positive psychological factors of positive psychological capital have a positive effect on retirees and retirees who are struggling with anxiety about retirement preparations, enabling a successful retirement life. Therefore, when operating a retirement preparation program, it is necessary to organize and operate a program that can expand positive psychological capital.

Purpose: The purpose of this study was to identify aging anxiety and influencing factors of middle-aged adults. Methods: Descriptive correlation design was used. Three hundred and three middle-aged adults participated in the study and completed the questionnaires in the period from September 11 to October 15 of 2011. The data was analyzed using independent t-test, one-way ANOVA, Scheff$\acute{e}$ test, Pearson correlation coefficients, and hierarchial multiple regression analysis. Results: Aging anxiety of middle-aged adults was higher than a moderate level. Socio-demographic variables such as age, religion, education, economic level, perceived health status and experience of living with older adults influenced significantly on aging anxiety. In contrast, general self-efficacy, aging knowledge and attitude toward older adults were negatively correlated with aging anxiety. Hierarchial multiple regression analysis incorporating these variables showed an explanation rate of aging anxiety at 21%. And religion, perceived health status, attitude toward older adults, and general self-efficacy were statistically significant among variables that influence on aging anxiety. Conclusion: The findings of this study suggest that senior preparation programs that can enhance self-efficacy, induce positive attitude on older adults and promote health should be implemented to reduce aging anxiety of middle-aged adults.

Purpose: This study was conducted to identify the relationship of health status, aging anxiety, social networking, generativity, and happiness and to investigate the main factors influencing happiness of late middle-aged adults. Methods: The study collected data from a total of 153 middle-aged men and women aged 50 to 64 years old from a consumer panel of Macromill-Embrain, the biggest online survey provider in Korea. The data were analyzed using descriptive statistics, Pearson's correlation coefficient and a stepwise multiple regression using the SPSS 22.0 program. Results: The subjects' happiness mean score was 16.17±9.29. Statistically significant differences in happiness were found according to education (F=4.38, p=.014), economic status (t=5.13, p<.001), and religion (t=2.18, p=.031). Happiness was correlated significantly with health status (r=.41, p<.001), aging anxiety (r=-.62, p<.001), family support (r=.43, p<.001), friend support (r=.36, p<.001) and generativity (r=.63, p<.001). The factors influencing happiness of late middle-aged adults were generativity (𝛽=.37, p<.001), aging anxiety (𝛽=-.35, p<.001), family support (𝛽=.20, p<.001), and economic status (𝛽=.13, p=.033). The explanatory power of the model was 58.0%. Conclusion: This study will be used as basic data when developing a nursing intervention program for successful aging by identifying factors that affect the happiness of late middle-aged adults.

This study aims to understand public perceptions of aging Korean society and related factors in the context of population aging and generational difference. Data are from 1,498 individuals older than 20 who were recruited through the quota sampling technique. Results indicated that the respondents reported less then three as the number of positive aspects of aging Korean society. Among the factors related to population aging, such as knowledge about aging, perceptions about family care, anxiety about later life, and perspectives about generational conflict, anxiety about later life was shown to be negatively associated with perception of aging Korean society across age groups. Respondents 65 and older showed more positive perception about aging Korean society and this association was conditioned by perspectives about generational conflict. Perspectives about generational conflict revealed positive associations with perception of aging Korean society among respondents aged 20-44 and 45-64, while no association was found among those 65 and older. Discussions focused on ways to alter perceptions of aging Korean society and needs for future research on this topic.

The purpose of this study is to compare the perceptions of loneliness, death anxiety, and social capital among older adults living in urban and rural communities and to examine the moderating effects of social capital on the relationship between loneliness and death anxiety. Utilizing the survey data collected by the Aging Society and Social Capital Research Center in 2018, we analyzed 839 older adults living in urban areas and 322 rural older adults living in rural areas. We used descriptive statistics, results from t-tests, and χ² tests to compare the rates of loneliness, social capital, and death anxiety perceived by older adults across urban and rural areas. The moderating effects of social capital on the relationship between loneliness and death anxiety were tested by logistic regression analyses for each group of urban and rural older adults. Compared to older adults living in rural areas, a greater number of older adults in urban areas reported death anxiety and higher levels of loneliness. However, the perceived levels of social capital were higher among rural older adults. The moderating effects of social capital on the relationship between loneliness and death anxiety were not found among older adults living in urban area, but, for older adults living in rural areas, social capital including social cohesion and social support moderated the relationship between loneliness and death anxiety. The results of this study suggest that regional differences shown in the perceptions of loneliness, death anxiety, and social capital should be addressed, when considering extensions of social capital and related interventions to deal with loneliness and death anxiety among older adults.

Objectives : The purpose of this study was to explore attitude and belief about menopause and severity of menopausal symptoms according to menopausal status. This study conducted a cross-sectional assessment of the effects of depressive symptoms and the severity of trait anxiety on the severity of menopausal symptoms. Methods : Participants were all outpatients at the psychiatric outpatient clinic of Korea University Guro Hospital. All participants, aged 40 to 64, had depressive or anxiety disorders and were divided into the premenopause, perimenopause, premenopause, and postmenopause groups. Menopause Rating Scale(MRS) was used to measure the severity of menopausal symptoms. The attitude toward menopause was examined by a self-report questionnaire regarding menopause. Beck Depression Inventory(BDI) and State-Trait Anxiety Inventory(STAI) were used to assess depressive symptoms and anxiety. Results : The severity of menopausal symptoms was not different among the groups according to menopausal status. There was a significant correlation between a negative attitude toward menopause and the severity of menopausal symptoms. Patients with moderate to severe depressive symptoms and trait anxiety had more severe menopausal symptoms. Conclusion : Negative attitude toward menopause, depressive symptoms, and anxiety had a significantly negative impact on the severity of menopausal symptoms. The results of this study suggest that treatment to relieve depressive symptoms and anxiety and intervention to reduce negative attitude toward menopause are required. Further studies with larger sample size are needed to evaluate potentially effects of depressive symptoms and anxiety on severity of menopausal symptoms in middle-aged female psychiatric patients.

This paper proposes a novel adaptive header-based power gating structure to compensate for the performance loss and the increased wake-up time of the power gating structures induced by the negative bias temperature instability (NBTI) effect. The proposed structure consists of variable width footers based on the two-pass power gating and a new NBTI sensing circuit for an adaptive control. The simulation results of the proposed structure are compared to those of power gating without the adaptive control and show that both the circuit-delay and wake-up time dependence of the power gating structure on the NBTI stress is minimized with only 3% and 4% increase, respectively while keeping small leakage power and rush-current. In this paper, a 45 nm CMOS technology and predictive NBTI model have been used to implement the proposed circuits.
