In the component assembly and composition technique of software architecture, It is operated that the existing composition techniques based on architecture, ACME, Wright etc., used in FIFO with the direct connection structure between components through connector's Role. But, when the non-synchronizing request of components that have different characteristics occurs, the FIFO techniques is applied to the connector is difficult to process and operate effectively because of the high performance component waiting the sequence order if the low performance component is allocated first. Thus, the allocated request process according to the priority considering the characteristics of each call components in connector is necessary to improve the operation of assembled component. In this research, we extend the connector part that is available in multiplex connection structure based on existent Wright specification. For service process requested from component, the connector part is designed and implemented to operating with priority sequence through calculating the weight of CPU use rate, bean requesting process time and memory use rate among the efficiency elements of assembled components. To verify the efficiency if this designed connector, we implemented 20 samples EJB components that have different efficiency characteristics and applied these samples components to designed connector. The operating results with this designed connector show that the efficient operation of whole system is possible though the processing time takes 481ms more than the time of the existing FIFO techniques.

This study attempts to examine the factors influencing the Caregiving responsibility of sibling without disability on their adult siblings with intellectual disability. For this purpose, a questionnaire survey was conducted on siblings without disability who have adult siblings with intellectual disability aged 18 years old or more and also who use services provided by 8 welfare centers for persons with disabilities in Seoul. With 132 valid responses, multiple regression technique was adopted in exploring a model for characteristics of adult with intellectual disability, a model for characteristics of siblings without disability, a model for relationship factors, and a comprehensive model. The findings of the study showed that the degree of disability in the model for characteristics of adult siblings with intellectual disability and the intimacy of siblings and social support in the model of relationship factors were significant. The result of the comprehensive model revealed that the degree of disability, the gender of the siblings without disability, the intimacy of siblings, and social support were significant. Especially, the relationship factors including the intimacy of siblings and social support were found to be the most significant factors in order to explain the caregiving responsibility. The findings of the study suggest that sibling program needs to be developed and disseminated in order to increase the understanding and the trust between adult with intellectual disability and sibling without disability, that a help is critical for adult with intellectual disability to extend the social network in which sibling without disability receives support from sibling without disability, family, friends, and other acquaintances around, and that different approach is needed in order to reduce caregiveing difficulties depending on the dependence of disability.

This is an empirical study that analyzes factors affecting the work-family compatibility of female wage workers with underage children. The analysis was conducted with 1,113 women from the 7th wave of the Korean Longitudinal Survey of Women & Families by Korean Women's Development Institute. As for research methods, multiple regression analysis was used in order to analyze the effects of 'social support(home support, maternity protection support, childcare and education services)', 'job characteristics', 'socio-demographic variables' and 'husband characteristics' on 'work-family compatibility and conflict'. As a result, it was analyzed that the husband's support for work life, gender inequality at work and women's educational training were the factors that strengthen work-family compatibility. It was also analyzed that gender inequality, use of childcare and education facility, number of underage children, age of husband, husband's satisfaction with caring support and husband's support for work life were the factors that cause conflict between work and family. Thus, if the policy of strengthening the work-family compatibility is a long-term policy, it appears that it is necessary to supplement and strengthen policies that can reduce conflict factors in the short term. It is hoped that the results of the study will be used as objective and academic data to strengthen the maternity protection and work-family compatibility of female workers with underage children.

This research was conducted to investigate the prevalence of depression and convergent factors related to depression in male and female wage workers. Using data from the 2014 and 2016 Korea National Health and Nutrition Examination Survey, 3,763 adults (1,888 males, 1,875 females) between the ages of 19 and under 65 were analyzed. Depression was measured by the Patient Health Questionnaire-9 (PHQ-9), and the depression (PHQ-9≥10) of all workers was 4.1% (3.2% for men, 5.0% for women). Multiple logistic regression analysis was performed to evaluate the depressive factors of male and female wage workers. In male workers, work-related characteristics such as employment type and working hours per week were found to be significantly related to depression even after adjusting for socio-demographic characteristics, health-related characteristics, and life style characteristics. However, in female workers, work-related characteristics did not expose a significant relationship, showing a difference from male workers. Therefore it is necessary to develop and implement workplace counselling or mental health promotion programs that take into account the gender characteristics of depression risk factors. Also, as health-related characteristics (diagnosis of depression, suicide plan, perceived stress level, unmet medical services, self-rated health status) were found to be related to depression for both male and female workers, continuous management of these factors is required.

The study was to improve the right to the enjoyment of culture of persons with visual impairment by increasing the accessibility to art exhibitions and exploring assistive measures through needs assessment survey of persons with visual impairment on arts exhibition. We used total 83 responses collected through an online survey. The result are as follows. First, watching movies at a teather was the most frequent leisure activity among persons with visual impairment, while respondents reported attending art exhibitions as the least frequent activity. Yet, 71.1% included attending art exhibitions as one of their top 5 culture and leisure activities. Most of the respondents reported the purpose of attending art exhibitions as fun. However, a primarily visual atmosphere prevented them from visiting the exhibition. Second, persons with visual impairment preferred approaching the art to have a closer look. More than about 50% of the respondents used their residual vision. Most of the respondents reported to use more than two senses when appreciating the exhibits. Moreover, respondents reported that devices/services for multi-sensory experiences would be helpful to appreciate the art. The findings imply that the consideration of the characteristics and needs of persons with visual impairment is required for establishing the environment of art exhibitions. This could further contribute to the improvement of the right to the enjoyment of leisure and culture of persons with visual impairment and lead to the realization of social integration.

Objectives: The aim of the study is to identify the success factors of 6 months of smoking cessation targeting male workers in small and medium-sized businesses. Methods: The subjects of this study were smoking male workers who had got the visiting services at a tobacco control center to stop smoking from January 2018 to December 2020. Total number of the participants was 767. Results: The male workers in small and medium enterprises had a success rate of 20.2% for smoking cessation for 6 months. With multiple logistic regression, the factors causing the differences in the success rate for 6 months of the workers were as follows. - The odds ratios (ORs)(95% confidence interval, CI) of the age group of under 29 and 40-49 years were 0.10 (0.03-0.29) and 0.43 (0.24-0.76), respectively, compared to the 50 years and older group. The ORs (95% CI) of the daily average of smoking group of 11-20 and more than 21 were 0.52(0.34-0.80) and 0.46(0.24-0.90), respectively, when compared to the group of 1-10. The ORs (95% CI) of the supporting persons for quitting smoking group of with spouse and other family were 1.99(1.18-3.34), compared to the group with no one. Conclusions: This study showed that the chance of success for smoking cessation for 6 months is higher when the subjects have spouses and other family Supporting persons for quitting smoking. And it also shows that the less they smoke a day and the older they are, the more likely it is to succeed in quitting smoking.

The purpose of this study was to identify the emotional and stress factors of the stroke victims living in the community and to investigate the effect of these factors on the level of social participation. Data collection collected data on the level of emotional awareness, stress, and social participation in welfare centers, public health centers, and stroke disabled people using community services. The level of social participation according to general characteristics was analyzed by descriptive statistics and one-way ANOVA. Emotional factors, stress factors, and social participation levels were analyzed by pearson correlation analysis and multiple regression analysis. As a result, there were no statistically significant factors in the sub-domains of emotional factors that affect social participation performance and satisfaction. In the sub-areas of stress factors, personal internal stress and interpersonal stress were statistically significant variables. The explanatory power showed social participation accomplishment was 34% and satisfaction was 33%. Therefore, various approaches should be made considering stressful factors to achieve rehabilitation into the local community, and additional research is needed to identify psychosocial variables that affect social participation.

This study was to investigate depressive symptoms of caregiving grandmothers in South Korea and related factors focusing on caregiving characteristics. The data were drawn from the fourth wave of Korean Longitudinal Study on Ageing (KLoSA). The study participants were 3,291 grandmothers who had at least one grandchild, and we limited our analysis to 127 grandmothers who had provided care for their grandchild(ren) during the past one year. As for the depressive symptoms, Center for Epidemiological Survey-Depression 10(CES-D 10) short version were applied. Caregiving characteristics including caregiving duration by weeks per year, caregiving hours per week and the number of grandchildren who received grandmother care were examined. A multiple logistic regression was performed to detect association between caregiving characteristics and depressive symptoms while adjusting for general socioeconomic characteristics and health status of caregiving grandmothers. The longer duration of caregiving lowered the depressive symptoms and in contrast, those who spent more hours for providing care to their grandchildren were more exposed to the depressive symptoms. Physical pain significantly increased their depressive symptoms and low income level were more likely to induce depressive symptoms. More detailed studies on grandchild caregiving patterns among grandmothers were needed. Also, tailored support policy and services should be considered to alleviate their burden and depression in the future.
