The purpose of this study is to examine the effect of economic stress on aging anxiety focusing on the moderating effect of motivations for participation in volunteering, and age. In order to accomplish these purposes, a total of 182 elderly who have been volunteering were used for final analysis. The results from the multiple regression showed that economic stress increases aging anxiety among elderly and motivations for participation in volunteering are likely to mitigate aging anxiety. Also, aging anxiety is expected to be lower as people are older and have higher self-oriented motivation for volunteering. Based on the result, political and practical implications are discussed.

Coolant rubber hoses for automotive radiators can degrade under thermal and mechanical loadings and thus fail owing to the influences of locally formed electricity. In this study, an advanced test method was developed to simulate the failure of a rubber hose. The aging behavior of carbon-black-filled ethylene-propylene diene monomer (EPDM) rubber used as a radiator hose material under a combination of electrochemical stresses and tensile strain was analyzed. The changing behaviors of the current and the resistance as a function of the aging time were analyzed in consideration of the tensile strain, voltage, and aging temperature. Sectioned specimens clarified the failure mechanisms of the aged skin layer under the combined electrochemical stresses.

Coolant rubber hoses for automobile radiators can be degraded and thus failed due to the influence of contacting stresses of air and coolant liquid under thermal and mechanical loadings. In this study, for EPDM(ethylene-propylene diene monomer) rubber conventionally used as a radiator hose material the aging behaviors of the skin part due to thermo-oxidative and electro-chemical stresses were nondestructively evaluated. Through the thermo-oxidative aging test, it was shown that the surface hardness IRHD(International Rubber Hardness Degrees) of the rubber increased with a considerable reduction of failure strain. On account of the penetration of coolant liquid into the skin part the weight of rubber specimens degraded by electro-chemical degradation(ECD) test increased, whereas their. failure strain and IRHD hardness decreased largely. The penetration of coolant liquid seemed to induce some changes in inner structure and micro hardness distribution of the rubbers. Consequently, EPDM rubbers degraded by thermo-oxidative aging and ECD could be characterized nondestructively by micro-hardness and chemical structure analysis methods.

The purpose of this study was to examine the attitude toward own aging among community-residing elderly and the predictors of the attitude focusing on personal resources, social support, and social participation. Data were collected from 198 elders aged 60+ with the cooperation of several social service center for the aged, senior centers, and senior citizen associations in Daejeon Metropolitan City. SPSS 22.0 software was used for descriptive analysis, correlation analysis, and hierarchical regression analysis. The results showed that (1) the research participant elderly's attitude toward own aging indicated fairly negative perception of their own aging; (2) self-esteem and economic status were statistically significant factors indicating the higher levels of self-esteem and economic status predicting the positive attitude of their own aging; (3) emotional support from family was statistically significant factor that predicted the positive attitude of their own aging; (4) the level of social participation was also statistically significantly associated with the positive attitude; (5) In the full model of all independent variables, the significance of emotional support from family and social participation disappeared, but self-esteem and economic status among personal resources remained statistically significant influential factors. Based on the findings, suggestions for social welfare policy and practice to improve community-residing elderly's positive attitude toward their own aging were discussed.

This study examined the factors influencing aging anxiety in university students. The participants were 239 nursing students from one university in Seoul. Data were collected from September to December in 2014 and analyzed using descriptive statistics, Pearson's correlation coefficient, and multiple regression. The average score for aging-anxiety was 2.94, for knowledge about the elderly 18.92, for attitude toward the elderly 65.5, for participants' supporting awareness of old parents 4.05, and for self-esteem 3.07. There were negative correlations between aging anxiety, attitude toward the elderly, supporting awareness of old parents, and self-esteem. Aging-anxiety was significantly influenced by age, gender, living with grandparents, attitude toward the elderly, supporting awareness of old parents, and self-esteem. In view of the results of this study, one of the strategic ways to help college students reduce aging anxiety is to provide an opportunity to participate in activities that they can experience positive relationship with elderly.

With the emergence of Internet-of-Things (IoT) computing, it has become possible to acquire users' health-related contexts from various IoT devices and to diagnose their biological aging through analysis of the IoT health contexts. However, previous work on methods of aging diagnosis used a fixed list of aging diagnosis factors, making it difficult to handle the variability of users' IoT health contexts and to dynamically adapt the addition and deletion of aging diagnosis factors. This paper proposes a design and methods for a dynamically adaptable aging diagnosis framework that acquires a set of IoT health contexts from various IoT devices based on a set of aging diagnosis factors of the user. By using the proposed aging diagnosis framework, aging diagnosis methods can be applied without considering the variability of IoT health contexts and aging diagnosis factors can be dynamically added and deleted.
