This study focused on the relationship between elderly's participation in lifelong education(participation availability, participating fields) and ego integrity. To verify the correlation of two variables, mediating model structured by life satisfaction was used. The data was Seoul Welfare Panel Data made by Seoul Welfare Foundation in 2010 and the total subject was 1,862 elderly aged over 60. When it comes to research methods, structured equation analysis for verifying the mediating effect was practiced. The findings are as follows: First, life satisfaction did function as partial mediator on relationship between elderly's participation in lifelong education and ego integrity. Second, elderly's life satisfaction increased as participating in field of language, not in field of culture and art. Ego integrity of elderly was increased as participating in field of culture and art, not in field of self-improvement and hobby. This study indicates theoretical and practical interventions to promote elderly's lifelong education based on the conclusion elderly's lifelong education participation in the aging society has positive effects on life satisfaction and ego integrity are meaningful for successful aging.

The purpose of this study is to provide a fundamental data and establish policies for the utilization of closed schools in Korea. The closed schools have been increased in Korea because not only the birth rate, and the number of students have been decreased, but also a greate number of people have moved to big cities or the elderly population is increasing. In this context, this research explores the current circumstance of Japan where experienced the similar phenomenon before Korea had. The results of this study are summarized as follows: The reason for the closed schools in Japan is a decrease in population due to the urbanization and reducing students themselves by aging. The recycling proportion of the closed schools is only approximately 62% in Japan. It means that fewer facilities have been recycled due to the transfer of the managemental departments and the lack of budgets for purchasing the closed schools. As the number of children decreases, but elderly people increases as the same time, it is necessary to positively examine the transition of the closed schools to new facilities for the elderly people. Even though the number of children had been declined, and it is recently turning back to an increasing of the residential children in 23 districts of Tokyo, there are still existing many closed schools. This phenomenon is caused by the decrease of the children and residential areas due to the aging and urbanization. For these reasons, there are many diverse demands for the practical and valuable recycling of the closed schools. However, it seems that there are few cases of successful disposal or transfer of management to other suitable ministry. Therefore, it is necessary for the closed schools to be remodeled the facilities required by current residents.

This study aims to analyze the sizing information of women's ready-to-wear pants as indicated on online retail websites and to suggest better sizing communication that can assist customers in making successful apparel size selections. We gathered size specifications and size reference information for basic straight pants from 34 online apparel retail websites. Although the Korean standard recommends labeling the body dimension-based sizing code and specification, most websites preferred to use various types of sizing codes. Body measurements were only used by a few websites, and garment dimension descriptions were the most common method to indicate product size. Many websites provided size reference information through customer review boards and fit model images, however, there was insufficient body size information to allow customers to infer the fit of their body type. When using the size guidance tools, the major data input points were stature and weight measurements. However, the waist measurements of pants sizes guided only by stature and weight values revealed inconsistent ease allowance for corresponding body size populations, especially in the overweight group. Based on our findings, we propose a more effective method of communicating the size information of pants online. We expect that this will contribute to the efficiency of online apparel product display and build a better shopping environment that satisfies both sellers and consumers.

Cancer cells predominantly generate energy via glycolysis, even in the presence of oxygen, to support abnormal cell proliferation. Suppression of PDHA1 by PDK1 prevents the conversion of cytoplasmic pyruvate into Acetyl-CoA. Several PDK inhibitors have been identified, but their clinical applications have not been successful for unclear reasons. In this study, endogenous PDHA1 in A549 cells was silenced by the CRISPR/Cas9 system, and PDHA1^WT and PDHA1^3SD were transduced. Since PDHA1^3SD cannot be phosphorylated by PDKs, it was used to evaluate the specific activity of PDK inhibitors. This study highlights that PDHA1^WT and PDHA1^3SD A549 cells can be used as a cell-based PDK inhibitor-distinction system to examine the relationship between PDH activity and cell death by established PDK inhibitors. Leelamine, huzhangoside A and otobaphenol induced PDH activity-dependent apoptosis, whereas AZD7545, VER-246608 and DCA effectively enhanced PDHA1 activity but little toxic to cancer cells. Furthermore, the activity of phosphomimetic PDHA1 revealed the complexity of its regulation, which requires further in-depth investigation.

This article examines features and implications of 'new northeast phenomenon' in China's new normal period. Different from previous studies with economy as a single factor, this paper regards the northeast phenomenon as not an single economic phenomenon but a compound socio economic phenomenon that economic, demographic and financial issues are linked together. This study finds that since 2014 decline of economic growth, deepening of population decline and brain drain, accelerated aging, the increase in fiscal deficit and a surge in social security spending, these phenomena occur simultaneously and influence each other, forming a vicious cycle in northeast China, and also finds that the difficulty of 'new northeast phenomenon' lies in this compound features. If so, what are the implications of 'new northeast phenomenon's' these features for China as a whole? This study proposes two points. First, based on the recent changes in some relevant situations in China, northeast region can be regarded as a microcosm of China, northeast phenomenon is likely to spread to other regions of China in the near future, it will become a common phenomenon all over China. Second, the emergence of the 'new northeast phenomenon' in the new normal period requires deep reflection and rethinking about the fundamental effect of the regional development strategies, such as 'The Development of the Western Region', 'The Rise of Central China', 'The revitalization of the Northeast', implemented since the reform and development. The 'new northeast phenomenon' has become one of the most urgent problems to be solved by the Chinese government, if the solution is successful, it can be a very useful direction for reconstructing regional development strategies in contemporary China.

Objective : The typical decline in function due to aging includes limitations in vision, hearing, cognitive function, and activities of daily living. Therefore, this study evaluated the mediating effect of cognitive function on the relationship between vision and hearing and activities of daily living. Methods : The participants in this study were 36,767 persons from the long-term care database on older adults provided by the National Health Insurance Sharing Service. The extracted variables were: (i) independent variables: visual and hearing; (ii) dependent variables: basic and instrumental daily living activities; and (iii) mediator variables: cognitive function. Regression analysis was performed evaluate the mediating effects of the extracted variables. Results : Cognitive function showed a mediating effect of 30% on the relationship between vision and basic daily life activities and 42% in the relationship with instrumental daily life activities. The mediating effect was 50% in the relationship between hearing and basic activities of daily living, and 53% in the relationship with instrumental activities of daily living. Conclusion : Prevention programs for functional decline due to aging are in progress in Korea. Based on the results of this study, establishing a prevention program would help promote successful aging.

This study examines the vocational adjustment experiences of elderly men who chose a creative occupation after retirement. The aims are to understand the related meanings and to provide specific empirical data on the elderly who hope to start a creative occupation. Five men aged 65 years or older who chose a creative occupation after retirement were enrolled in the study. Data were collected through in-depth interviews with the participants. The collected data were qualitatively analyzed, and a total of 7 categories, 25 subcategories, and 132 concepts were identified. The seven categories were "challenge led by a sense of freedom," "reflection of the need for 'fun,'" "difficulties and limitations felt by a non-expert," "concerns and effort to afford the increasing expenses," "joy for accomplishment," "ways to utilize my creativity," and "reward from increased social participation." The participants felt that adjusting to a creative occupation was a process by which their potential creativity was expressed. They felt the joy of working that they had not felt before, and the series of processes by which they overcame difficulties during work and increased their social participation were in line with the goals of creative aging. In order to help older adults in Korea to choose and adjust to creative occupations in their older adulthood, there is a need for creative-occupation-related education prior to retirement and for various policies and practical efforts that consider the change of social environment. Furthermore, our findings suggest that choosing a creative occupation after retirement is an effective measure for promoting successful aging among the elderly in Korea.

Purpose: This study was conducted to compare the level of cognitive and physical function by the level of social disengagement in institutions and community dwelling elderly. Method: The study subjects were 209 people whose age ranged from 65 to 94. The data were surveyed with social disengagement index, MMSE-K, and ADL, and analysed by SPSS 11.0 using frequency, t-test, ANCOVA and ANOVA. Results: 1) The level of social disengagement was 1.67 in institution and 3.25 in community elderly, and showed statistically significant difference (F=41.07, p<.001). 2) There were statistically significant difference in MMSE-K (F=15.51, p<.000), and activity of daily living (F=9.65, p=.002) between two residence after control the age, gender, religion, allowance and number of children. 3) There were statistically significant difference in MMSE-K (F=6.55, p=.002) by social disengagement in community dwelling elderly. Conclusions: Programs for successful aging to reduce social disengagement should be developed that stimulate social activities and then improve cognitive function for the elderly. For these, establishing social policies in nation and local government is needed. Especially, these policies should be conducted among the elderly with low-income living in institutions.

Patients with congenital heart diseases (CHD) are confronted with early- and late-onset complications, such as conduction disorders, arrhythmias, myocardial dysfunction, altered coronary flow, and ischemia, throughout their lifetime despite successful hemodynamic and/or anatomical correction. Rhythm disturbance is a well-known and increasingly frequent cause of morbidity and mortality in patients with CHD. Predisposing factors to rhythm disturbances include underlying cardiac defects, hemodynamic changes as part of the natural history, surgical repair and related scarring, and residual hemodynamic abnormalities. Acquired factors such as aging, hypertension, diabetes, obesity, and others may also contribute to arrhythmogenesis in CHD. The first step in evaluating arrhythmias in CHD is to understand the complex anatomy and to find predisposing factors and hemodynamic abnormalities. A practical stepwise approach can lead to diagnosis and prompt appropriate interventions. Electrophysiological assessment and management should be done with integrated care of the underlying heart defects and hemodynamic abnormalities. Catheter ablation and arrhythmia surgery have been increasingly applied, showing increasing success rates with technological advancement despite complicated arrhythmia circuits in complex anatomy and the difficulty of access. Correction of residual hemodynamic abnormalities may be critical in the treatment of arrhythmia in patients with CHD.

The South Korean society is rapidly aging, thereby highlighting the need to urgently prepare for the stabilization of housing for the elderly. In order to address such issues stemming from the elderly population, the South Korean government has been ramping up the supply of public silver houses for the elderly. Furthermore, it is necessary to select the optimal construction sites and conduct financial feasibility study on the selected sites in order to ensure a successful supply of public silver houses. In this study, the author proposed the need for building an integrated database by using geographic and demographic information, as well as the information on social welfare costs. Moreover, a concept for a system capable of performing optimal site analysis and feasibility study using the aforementioned information was suggested.
