The purpose of this study are the following two: first, to identify success level of elderly's Aging by their household types and second, to analyze the factors affecting successful aging. The results of this study are expected to be used as basic data for policy and program development for the successful life of the elderly. For this purpose, 699 single household, 1,412 couple household and 238 couple/child household data in personal survey and supplementary survey of the 4th Korean Retirement and Income Study. According to the analysis, the level of successful later life of single household is lower than that of couple or couple/children household. Multiple regression analysis was conducted to identify the factors affecting successful aging in single household. The results showed that economic activity, economic independence, housework, neighborhood affairs, family relations, and parent-child relationship were statistically significant. Economic independence, physical health, friendship, and parent-child relationship were found to affect in couple household. Physical health and friendship were found to be significant factors for successful aging in couple/child household.

The purpose of this research is to critically analysis the applying trend of the successful aging research on the baby boomers Generation. Research method is qualitative content analysis and this study was analyzed by concepts, factors, heterogeneity and variety of generation. The results of the analysis on 124 domestic articles on the journals on the successful aging from 2000 to 2016 are as follows: most of concepts in researches are about economic problems. In a research model, social environmental factors are barely considered. Heterogeneity and a few studies showed identities and varieties of generation. Based on these results, several suggestions are presented; First, consideration about the concepts of successful aging On a broad range is required. Secondly, concepts and influence factors should be clearly identified. Third, factors related to life itself in aging and macro social environment than factors of individual unit focused on economic value should be used. In addition, new age-old cultual value should be discussed to understand the Inherent traits of baby boomers. Lastly, studies to discuss varieties which are caused by age and gender of the baby boomers are needs to proceed.

Purpose: This study was done to investigate factors influencing successful aging in middle-aged women. Methods: A convenience sample of 103 middle-aged women was selected from the community. Data were collected using a structured questionnaire and analyzed using descriptive statistics, two-sample t-test, one-way ANOVA, Kruskal Wallis test, Pearson correlations, Spearman correlations and multiple regression analysis with the SPSS/WIN 22.0 program. Results: Results of regression analysis showed that significant factors influencing successful aging were post-traumatic growth and social support. This regression model explained 48% of the variance in successful aging. Conclusion: Findings show that the concept 'post-traumatic growth' is an important factor influencing successful aging in middle-aged women. In addition, social support from friends/co-workers had greater influence on successful aging than social support from family. Thus, we need to consider the positive impact of post-traumatic growth and increase the chances of social participation in a successful aging program for middle-aged women.

Laminated rubber bearing is very popular base isolation of earthquake engineering pertaining to the passive structural vibration control technologies. Rubber used in fabricating NRB and LRB can be easily attacked by various environmental factors such as oxygen, heat, light, dynamic strain, and organic liquids. Among these factors, this study carried out thermal aging test to investigate the effect of thermal aging on the mechanical properties of laminated rubber bearings in accelerated exposure condition of $70^{\circ}C$ temperature for 168 hours. The compressive-shear test was carried out to identify the variation of compressive and shear properties of the rubber bearings before and after thermal aging. In contrast to tensile strength and elongation tests, the hardness of rubber materials showed the increasing tendency dependent on exposure temperature and period. Based on the test results, the property changes of rubber bearing mainly aged by heat are quantitatively presented.

The purpose of this study was to identify predictive factors of successful aging and to determine mediating effect of transcendence between successful aging and influencing factors of community-dwelling elders in Korea. 162 elders were participated in this study who visited seniors welfare center and senior citizen center. Data were analyzed by PASW 18.0 for t-test, Pearson's correlation coefficients and hierarchical regression analysis. Transcendence, parent-child relationship, depression, spirituality and perceived economic status were statistically significant influencing factors, explained 77% of successful aging in community-dwelling elderly. The mediating role of transcendence was identified about parent-child relationship, depression, spirituality and perceived economic condition. The study findings demonstrated that transcendence was significant variable affecting successful aging. The variables affecting successful aging such as transcendence, parent-child relationship, depression, spirituality, perceived economic status can be utilized for nursing strategies to successful aging in community-dwelling elders.

In this study, an aging deformation statistical model for a unique high and steep rock slope was proposed, and the aging characteristic of the slope deformation was better reflected. The slope displacement was affected by multiple-environmental factors in multiple scales and displayed the same tendency with a rising water level. The statistical model of the high and steep rock including non-aging factors was set up based on previous analyses and the study of the deformation and residual tendency. The rule and importance of the water level factor as a non-aging unit was analyzed. A partitioned statistical model and mutation model were established for the comprehensive cumulative displacement velocity with the monitoring study under multiple factors and multiple parameters. A spatial model was also developed to reflect and predict the whole and sectional deformation character by combining aging, deformation and space coordinates. A neural network model was built to fit and predict the deformation with a high degree of precision by mastering its feature of complexity and randomness. A three-dimensional finite element model of the slope was applied to approach the structure character using numerical simulations. Further, a three-dimensional finite element model of the slope and dam was developed, and the whole deformation state was analyzed. This study is expected to provide a powerful and systematic method to analyze very high, important and dangerous slopes.

This study examined the personal and relational factors influencing the formation of body image among older persons. Aging-rel￡lted physical changes, health, marital relationship, cognitive age, and moods were personal and relationship factors explained for influence on the body image of older persons. Data were collected via a mail survey of older married couples residing in three US. metropolitan areas of Florida. A total of 94 married couples who were 60 years older participated in this study. Results indicated that aging-related physical changes, effect of physical changes on the self, self-assessed health, and evaluation of spouse's attractiveness, and perceived attractiveness (one's perception of the other spouse's appraisals of his or her attractiveness) were found to be significantly related to the body image of older men and women. For men, self-assessed health, evaluation of spouse's attractiveness, and perceived attractiveness were significantly related to body image while physical changes, effect of physical changes, and perceived attractiveness were found significant for women. The feelings of older persons about and satisfaction with their bodies and appearance were estimated by aging-related and relationship-related variables.

Converter transformers play important roles in high-voltage direct current transmission systems. This paper presents experimental and analysis results of the combined electrical and thermal aging of oil-impregnated paper at pulsating DC voltages. Breakdown voltages and time-to-breakdown of oil-paper specimens were measured by using short-time and constant-stress tests. The breakdown characteristics of combined electrical and thermal aging on insulation system were discussed. According to the relationship between failure time and aging temperature, the two-parameter Weibull model was improved. On the basis of the competing risk algorithm and the improved Weibull model, the two factors failure model was calculated. And the influence of temperature in the insulation system has been analyzed. This model performs better than the two-parameter Weibull model when both time and temperature are considered as variables in estimating the lifetime of oil-paper insulation.

Purpose: This was a methodological study that aimed to develop a measurement scale for aging anxiety among middle-aged women. Methods: In this study, construct factors were extracted, and a conceptual framework was established through an extensive literature review and in-depth interviews with middle-aged women. Under the conceptual framework, 44 preliminary items were constructed, and a preliminary scale of 25 items was completed after two rounds of expert validation and item review. For this study, data were collected from 201 women aged 40~59 years, and the construct validity and reliability of the preliminary scale were verified. Results: To verify the construct validity, exploratory factor analysis was conducted. Four factors containing 19 items were extracted. Concurrent validity of the developed scale was verified with Pearson's correlation analysis. The final scale comprised 4 factors ("Social valueless", "Physical weakness", "Concern about changes in appearance", and "Expectations of old age") and 19 items. The Cronbach's ${\alpha}$ value was .91. Conclusion: The scale for measuring aging anxiety in middle-aged women developed in this study validly reflected the peculiarities of aging anxiety in middle-aged women, who experience many physical, emotional, and social changes. The scale can be said to reflect the cultural background, as it reflected real experiences gained through in-depth interviews with middle-aged women.
