This study aimed to address the effect of poverty on depression and self-rated health in older adults living alone in Korea. In addition, this study identified the mediating effect of social participation on the poverty-depression and poverty-self-rated health relationships. The researcher conducted a secondary data analysis using the 6th wave of the Korean Longitudinal Study on Aging. The final sample was 1,093 older adults living alone. Using structural equation modeling, standardized coefficients of each path were analyzed. Then, the statistical significance of the mediating effect of social participation was addressed via analyzing direct, indirect, and total effects. Results show that older adults under poverty were more depressed and had a lower level of self-rated health than their counterparts. Moreover, frequent participation in religious gatherings, social gatherings, and leisure activities decreased depression in older adults living alone. Moreover, religious gatherings, social gatherings, and alumni meetings were positively related to self-rated health om older adults living alone. Significant mediating effects appeared in poverty-social gathering-depression, poverty-social gathering-self-rated health, and poverty-alumni meeting-self-rated health relationships. Based on the results, the researcher also discussed implications for social work practice.

This study examined the moderating effect self-rated health has on the association between grandparenting and depressive symptoms. The fourth wave (in 2012) of the Korean Longitudinal Study of Ageing (KLoSA) was used for the analyses (N=650). The Coarsened Exact Matching (CEM) method was applied in order to ensure randomness in the selection of grandparents who participated in grandparenting and those who did not. The dependent variable was depressive symptoms, the independent variable was grandparenting, and the moderating variable was self-rated health. Control variables were education level, age, household income, gender, marital status and life satisfaction. After matching data by CEM, weighted multiple regression was applied with STATA 13.0. Also, simple slope analysis and region of significance were performed to interpret the interaction terms. The results showed that self-rated health had a significant moderating effect. Specifically, for grandparents with high self-rated health, grandparenting was associated with a lower level of depressive symptoms. On the contrary, for grandparents with low self-rated health, there was no difference depending on whether they participated in raising grandchildren. Based on these results, we discussed the need for consideration of self-rated health for grandparents who participated in grandparenting.

본 발표에서는 베이지안이 생각하는 확률의 개념을 상호교환성(exchangeability)의 가정아래 어떻게 확장되어 해석되는지를 소개하고, 빈도학자들의 접근방법과 비교함으로서 베이지안에서 생각하는 확률이 어떠한 특징을 가지고 있는지를 설명하고자 하였다. 또한 Efron에 의하여 지적된 베이지안의 네 가지 문제점에 대하여 논의하고 특별히 과학적 객관성(scientific objectivism)의 한계점과 이러한 한계점을 베이지안에서 어떻게 해결하고 있는지에 대하여 논의하였다. 일반적으로 과학적 객관성에 대한 한계점은 빈도학자들의 방법론에서도 존재하게 된다. 즉, 연구자가 가설을 설정하고 이에 맞는 실험설계를 하고 유의수준을 설정하고 p값을 이용하여 의사결정을 내리는 모든 단계에서 연구자의 주관성이 들어갈 수밖에 없게 된다는 것이다. 베이지안 방법론에서는 이러한 비객관적인 체계를 인정하고 파악하여 사전확률(prior)에 포함시킴으로서 이를 객관적인 자료인 가능도함수(likelihood function)와 혼합하여 추론이나 의사결정을 진행하게 된다. 마지막으로 베이지안 학자들의 최근 객관적인 사전확률에 대한 다양한 형태의 연구를 소개하는 것으로 발표를 마무리하고자 한다.

It has been well known that there is a close relationship between health and depression among older adults. Under the purpose to mitigate and prevent the risk of depression caused by poor health, the changes in subjective health status'effects on depression depending on the level of age-friendly public service resources, and age were respectively examined in this study. Moderating effects analysis was conducted using 492 adults aged 55 years and over from '2017 age integration survey' data which had been collected nation-widely. Major findings are as follows. The inadequate subjective health status raises the level of depression. This tendency is weakened when the better age-friendly public service resources are presented. In contrast, age has no statistically significant effects on the relationship between two variables. As a result of reviewing the specific conditions to bring out the interaction effects, frail subjective health status increased depression of all age groups as the level of age-friendly public service resources is low. Particularly, for the participants aged average(age 66.6) and older, the negative effects of subjective health status on depression are likely to be lowered by the improvement in poor age-friendly public service resources. That is, the buffer effects of age-friendly public service resources are proved. Based on theses findings, several suggestions for health promotion and depression prevention of older adults were discussed.

This research aims to examine how military executive members and local residents mutually perceive the military family support. The 217 individuals from the military executive and the 191 local residents took part in this research. The results of this study are as follows: First of all, in the sense of the agreement, the respondents from the military executive had higher perception when it comes to the necessity of the community support, whilst the answer from their counterparts did not. Second of all, in terms of the congruence(1) on this issue, the perception levels that the each group of respondents showed are not corresponded, besides each group had different level of demands on the community resources according to the analysis of the congruence(2). Third, regarding the accuracy(1), the military executive members called for higher coverage of community supports whilst the local residents perceived that the executive members might be having less demands. The accuracy(2) too shows the different perception on the resources that the each group has. Last of all, for the meta-agreement, which indicates how each group found its counterpart's perception, were only corresponded at the lower level.

The outdoor recreation fever that is drastically increasing in Korea could be the result of the interaction between mass media and popular culture as well as increase of leisure time and disposable income. Thus, the purpose of this study is to specify how the exposure of outdoor recreation through mass media influences potential outdoor recreationists. In order to specify this decision-making process, playfulness, which is the intrinsic characteristic of adults' fun and play, was added to the theory of planned behavior, which has high explanation power regarding human behavior. As a result of the study, it turned out that playfulness significantly influences attitude, subjective norm, and perceived behavioral control, and that attitude, subjective norm, and perceived behavioral control also significantly influence behavioral intention. These results specify that playfulness is a factor that has a great effect on outdoor recreation that seeks deviant behavior.

It is known that the roughness is one of the most important metrics in assessing the sound quality. In this study, a new roughness model is suggested by combing the previous auditory filter model and several signal processing methods for the enhancement of calculation efficiency and accuracy. For testing the usefulness of the present model, the predicted responses are compared with the experimental data and it is observed that they are in good agreements. Also, it is found that the previous models have limitations to search frequency components mainly contributed to overall roughness. By modifying the correlation criteria of the present model, the revised model for the proper estimation of roughness-contributed components is embedded.

Recently many organizations have adopted 'untact' work due to social distancing caused by Coronavirus-19. To clarify some controversy about the effectiveness from 'untact' work, it is necessary to examine the cognition of organizational members. This study identified issues in 'untact' work from the literature review, analyzed the content of in-depth interviews with workers and managers experiencing 'untact' work, and compared both groups' cognition by applying the co-orientation model. Both groups pointed out the communication difficulty as the top disadvantage and showed no significant differences in job satisfaction, organizational commitment, and work-life balance. However, the two groups showed significant differences in their cognition about performance evaluation (agreement and workers' congruence) and productivity enhancement (workers' accuracy). This paper has an academic contribution in that it has focused on cognitive gaps between workers and managers, urges organizations to devise ways to reduce the gaps, and suggests future studies with quantitative approaches.

This study is about an interface design supporting collaborative learning activities in online environment in which people exchange their knowledge and give feedback on personal storytelling to each other. Interface design issues from the viewpoint of Computer Supported Collaborative Learning (CSCL) on digital media design are considered. Based on collaborative learning theories and analysis on the existing online collaborative sites about digital media, such as online forums for digital pictures and films, interface guidelines are suggested and the interface is designed. The interface design is evaluated through a pilot test. The interface for collaborative learning on personal storytelling is designed to support observation and to provide a scaffolding for valuable conversation. It is also designed to help intersubjectivity of online conversation and an easy access to media.
