The first aim of this study was to explore the roles of personality variables on work motivation and job satisfaction. The second purpose was to setup a path model, in which the personality variables would impact on work motivation and job satisfaction. The third purpose of the current study was to examine medation effects of work motivation between personality variables and job satisfaction. In total, 280 older employees who worked in the various fields participated at this study. The reuslts of hierachial regression analysis found that agreeableness, conscientiousness, and interanl locus of control positively predicted on work motivation. The results indicated that openness to experience and neuroticism negatively influenced on work motivation. Also, we found that agreeableness, conscientiousness, and self-esteem positively predicted on job satisfaction. The resutls of path analysis showed that work motvation mediated the relationship between agreeableness, conscientiousness, and interanl locus of control and job satisfaction, respectively. Finally, implicaions of the results, limitations of this study, and directions of future research were discussed.

The purpose of this study is to compare rational process of active ageing and productive aging based on the theory of planned behavior. The effect of post-retirement may be influenced by attitude, subjective norms, and perceived behavioral control for old aged workers, then we tested the effect of mediating role of post-retirement preparation on active ageing and productive aging. And we conducted additional analyses of mediating role of post-retirement preparation respectively. Conducting a survey research to 192 employed old aged workers, the data was analyzed by Structural Equation Modeling. The result of this study found the positive effects of attitude and perceived behavioral control on active ageing through post-retirement preparation. There were negative effect of subjective norms and positive effect of perceived behavioral control on productive aging through post-retirement preparation. According to additional analyses, the mediating effect of social post-retirement preparation was significant on active ageing, and the mediating effect of emotional and social post-retirement preparation was significant on productive aging. Suggestions for future research and practical implications were provided based on the findings.

There has neither been enough research on how to approach the concept of active aging through an integrated view nor an examination to verify the relationship between preparation for old age and active aging in later life. Therefore, this research aims to verify that the elderly, who have prepared for their later life, affected their active aged life. In addition, by setting up self-efficacy and social support as mediator in the research model, this paper looks into the psycho-social resource mechanism of the relationship in depth. In order to verify the correlation of two variables, the Seoul welfare panel data, a mediating model structured by psycho-social resources created by Seoul welfare foundation in 2010, was used. The total sample size was a group of 1,492 elders aged over 65. When it came to our research methods, structured equation analysis was applied to verify the mediating effect and theoretical background. The results revealed that physical preparation, financial preparation, social preparation and leisure preparation directly affected their active aging level positively, thus, psycho-social resources showed a partial mediating effect between preparation for old age of the past and active aging level. The research implications are as follows. First, this research makes an effort to approach the concept of preparation for old age with an integrated perspective through making a construct by entire preparation types. Second, it will attempt to verify the relationship between preparation for old age in the past and active aging in terms of multi-dimension is meaningful. Third, this research reveals the function of psycho-social resource, self-efficacy and social support within the relationship. As far as the partial mediating effect is concerned, preparation for old age education for the middle-aged class should be modified as a decent field to enhance of the elderly.

The purpose of this study was to investigate the relationship among perceived environmental factor, active aging and self-rated health for active senior golf participants. The collected data were analyzed using the SPSS 18.0 and AMOS 18.0 programs for Windows. Frequency analysis, confirmatory factor analysis, reliability analysis. After correlation analysis and structural equation model analysis were used. As a results derived through the research are as follows. First perceived environmental factor had a positive effect on active aging. Second, active aging had a positive effect on self-rated health. Third, perceived environmental factor had a positive effect on self-rated health. Fourth, active aging mediated the relationship between perceived environmental factor and self-rated health.

The present study aims to examine the mediating role of life satisfaction in the relationship between productive activities and future time perspective in later life. Drawn from the 7^th wave of the Korea Longitudinal Study of Aging, our sample consists of a total of 6,756 older adults aged 55 and over. Complex samples analyses were conducted the relationship between productive activities, life satisfaction and future time perspective measured in two dimensions (i. e., life expectancy and job expectation). Results from complex samples analysis showed that productive activities were associated with life satisfaction and future time perspective. Employed older adults including unpaid family workers tended to have higher levels of life satisfaction and future time perspective (i.e., life expectancy and job expectation) than their counterparts. The relationship between productive activities and future time perspective was mediated by life satisfaction. Findings suggest that engaging in productive activities influences better satisfaction with life among older adults, which is eventually linked to an expansive view of the future. Policy implications were discussed that promoting productive activities in later life and age-friendly working environment should be encouraged.

Since the early 2000s, Korea has continued to increase the proportion of the elderly population due to low fertility and increased life expectancy. As a result, Korea has now entered the aging society. Because of this demographic change, proportion of active elderly have increased, and many academics, such as sociology, economics, and psychology, have conducted various studies on the active elderly. This study focused on active elderly based on the activity theory of old age and the positive effect of small community participation activity on the elderly. The purpose of this study is to examine whether active elderly' participation in everyday activities, small community participation of the elderly affect citizen participation actively in society as a citizen, and in the process, mediates the effect of small community cohesion and the moderating effect of small community selfishness. This study performed a stepwise regression analysis and a hierarchical regression analysis of 700 elderly people who are participated actively in various small communities. As a result, the partial mediating effect of small community cohesion was shown in the relationship between participation in everyday activities and citizen participation, and the moderating effect of small community selfishness was also shown. These findings suggest that government and interested parties need to develop and implement policies for the small community participation of elderly citizens in consideration of their small community activities, small community cohesion and small community egoism.

Computer algebra system (CAS) calculators are becoming increasingly common in schools and universities. While Hey offer quite sophisticated mathematical capability to teachers and students, it is not clear at present how they may best be employed. In particular their integration into students' learning and problem-solving remains an issue. In this paper we address this issue through the lens of a study that considered the introduction of the TI-89 CAS calculator to students about to enter university. We describe a number of different aspects of the partnership they formed with the calculator as they began the process of instrumentation of the CAS in their learning.
