  • The purpose of this study was to research the effects of socio-demographic factors and values in each group on satisfaction with life by categorizing the activity types of the elderly into volunteer work and economic activities. The subjects of this study were 60 years an old higher. The questionnaires were categorized depending on activity types and collected. The voluntary work group consisted of 201 people (76 males, 36.8% and 125 females, 62.2%), The economic activity group consisted of 219 people (127 males, 58.0% and 92 females, 42.0%). The SPSS 14.0 Windows program was used to analyze data. Frequency, average, standard deviation, factor analysis, Pearson correlation coefficient, t-test, One-Way ANOVA analysis, and hierarchical multiple linear regression were analyzed. The major findings of this study indicate that the elderly in the voluntary work group have a high collectivism value, higher income earned by performing economic activities, and good cognitive health affected by a high satisfaction with life. From these research results, it was proved that a collectivism value is a common factor that affects satisfaction with life in both of the economic activity group. Those who were older had a traditional collectivism value. The voluntary work group showed a stronger collectivism value and higher satisfaction with life than the economic activity group. Thus, the diverse types of voluntary work should be developed and a systematic system should be established as methods for improving quality of life and satisfaction.

  • Knowledge about somatization (somatic manifestation of psychological distress symptoms) among immigrant populations is limited. While several studies have recognized somatization as a culturally distinctive expression of depression amongst older Korean immigrant population, somatization has not been incorporated into the comprehensive empirical model for depression of this population. In order to improve our general understanding of the phenomenon, the objective of this study is to empirically investigate principal contributing factors of somatization as well as inter-relationships among them. Data were collected from a cross-sectional community survey of 234 older Korean immigrants ($$age{\geq_-}55$$) in the New York metropolitan area. The statistical methodology employed a robust hierarchical regression procedure that iteratively downweights outliers. The results indicated that living arrangement, greater numbers of physical illnesses, and depression were significant explanatory factors of somatization. Furthermore, physical illness had a significant joint effect with perception of health on somatization, which confirms that positive perception of health exerts a moderating effect on the relationship between physical illness and somatization. The knowledge obtained from this study will contribute toward extending our knowledge on somatization and implementing more culturally sensitive mental health services for this population.

  • Solutions for elderly health issues need to be found that take into account not only a medical perspective, but also interactions with social conditions such as socioeconomic status. With this in mind, this study aims to understand how socioeconomic status leads to health inequalities for the elderly. Specifically, this study investigates the mediating effects of socioeconomic status(income and education levels), health activities as an intermediary of the three dimensions of physical health(medical health, functional health, subjective health), accessibility of medical facilities, social participation, and social network. To test the research model, a secondary data analysis was conducted on the 2014 National Survey of Senior Citizens. The participants of the study were 10,451 elderly men and women aged 65 and above. To test the mediated model, hierarchical multiple regression analysis was conducted following the procedures suggested by Baron and Kenny(1986). In addition, a Sobel test was conducted to test the mediated model's significance. According to the analysis, the effects of income and educational levels on the health of the elderly were not the same. Additionally, different results were found depending on health dimensions. However, the overall direction of the results showed that the socioeconomic status of the elderly creates health disparities, and health behaviors, accessibility of medical facilities, social participation, and social network had significant mediation effects between socioeconomic status and physical health. Study findings especially worth noting are as follows: education was shown to have a stronger effect on health than income; effects of social integration factors such as social participation were highlighted; and significant mediating effects on the accessibility of medical facilities remained even after taking residential area into account. Results of this study shed light on health inequality mechanisms due to socioeconomic conditions and the need to find alternatives to alleviate these problems.

  • This study was carried out to empirically analyze the hypothesis that the impact of the welfare status on the welfare attitudes is moderated by each individual's level of confidence in government. To do this, this study focused on the welfare status known as the significant predictors of welfare attitudes and measured the welfare status as a gap between 'welfare contribute' and 'welfare benefit' in a single dimension, which is defined as 'material sacrifice'. Also, this study examined the main effect of material sacrifice and trust in government on the welfare attitudes and moderating effect of trust in government on relationship between material sacrifice and welfare attitudes. This study was performed with secondary data from 8th year of "2013 Korea Welfare Panel Study". Hypothesis of this study were verified using hierarchical multiple regression analysis. The major findings of this study are summarized as follow. 'Material sacrifice' was found to be negatively associated with the welfare attitudes. However, as the confidence in which social policies will be carried out competently by government increases, it was confirmed that the negative effect of material sacrifice on the welfare attitudes was moderated. It suggests that self-material interests associated with welfare could be moderated by beliefs and expectations about the government's functions, which means that expanding the reliance on the social policy is an important task in order to lead a social consensus for the welfare expansion.

  • In this paper, we propose a prototype system for abnormal sound detection and identification which detects and recognizes the abnormal situations by means of analyzing audio information coming in real time from CCTV cameras under surveillance environment. The proposed system is composed of two layers: The first layer is an one-class support vector machine, i.e., support vector data description (SVDD) that performs rapid detection of abnormal situations and alerts to the manager. The second layer classifies the detected abnormal sound into predefined class such as 'gun', 'scream', 'siren', 'crash', 'bomb' via a sparse representation classifier (SRC) to cope with emergency situations. The proposed system is designed in a hierarchical manner via a mixture of SVDD and SRC, which has desired characteristics as follows: 1) By fast detecting abnormal sound using SVDD trained with only normal sound, it does not perform the unnecessary classification for normal sound. 2) It ensures a reliable system performance via a SRC that has been successfully applied in the field of face recognition. 3) With the intrinsic incremental learning capability of SRC, it can actively adapt itself to the change of a sound database. The experimental results with the qualitative analysis illustrate the efficiency of the proposed method.

  • This study was originated from the idea that it would be important for caring service of community children center to be positioned as the institution to strengthen the public nature and provide quality care services to children. In particular, competencies of the employees in community children centers play an important role and the quality of children care services is the crucial evaluation parameter for those institutions. The objectives of this study are to investigate the effects of the competency levels of the employees in community children centers on the service quality to children and to verify the mediated effect of self-efficacy on their service quality to children. With respect to the data analysis methods, hierarchical regression analysis was performed. Barron & Kenny's method was used to understand the mediated effect of self-efficacy. Also, Sobel test was performed to investigate the significance of mediated effect of self-efficacy. The study results are, first, the service quality to children might be differed by the level of competencies of the employees in community children centers; and second, partial mediated effect of self-efficacy was found between their competencies and service quality to children. These results implicate that service quality to children can be improved by strengthening competencies of the employees in community children centers and enhancing their self-efficacy. It is necessary to try to improve the service quality by enhancing competencies and self-efficacy of the employees in community children centers, which will lead those institutions to play a crucial role in the caring services.

  • This study was conducted on 253 artists for a month from April 19, 2020 to study the influence and countermeasures of COVID-19. The analysis results are as follows. First, as a result of frequency analysis, the timing of the occurrence of COVID-19 and the period of the decrease in artist's artistic activities were consistent, and the subjective socioeconomic level perceived by the artist was degraded from COVID-19. Second, as a result of the multivariate variance analysis, the income level and employment environment of artists affected the variables associated with COVID-19. Third, as a result of the hierarchical analysis analysis, the income level and the socioeconomic level changes due to COVID-19, and concerns about COVID-19 infections, have been shown to have had a significant impact on the level of stress felt by artists. Fourth, as a result of qualitative research, the artist reported that he was experiencing economic and psychological difficulties due to the influence of COVID-19, and emphasized the need for policy support as a way to cope with them. We hope that the results of this study will be used as empirical data in the process of developing support systems and programs for artists experiencing economic constraints and social alienation due to COVID-19.
