This study was conducted to determine the quality of sleep, and its association with the sociodemographic characteristics, health-related characteristics, and job-related characteristics among male workers in small-scale manufacturing industries with fewer than 50 members. A self-administered questionnaire was distributed to 856 male workers from April $1^{st}$ to June $30^{th}$, 2011. The survey items included the variables of sociodemographic, health-related, job-related, and quality of sleep. As a result, the quality of sleep according to the PSQI of the study subjects revealed 32.0% to be good and 68.0% to be poor. The quality of sleep assessed by hierarchical multiple regression analysis was significantly lower in the married group, those with lower BMI, and those with a lower level of subjective health status, non-smoking, alcohol drinking, without regular exercise, coffee drinking, blue color, had a longer of working hours, subjective health status, had a visiting out-patient department, and had a history of hospitalization. With the above model, the job characteristics had 13.1% explanatory power. This suggests that the quality of sleep (PSQI) has more power when combined with the job characteristics.

This study suggests different improvement practices of adolescents' multicultural acceptability to compare the factors influencing multicultural acceptability with elementary and middle school students. The data used in this study come from the Korean Child and Youth Panel Study(KCYPS) of the National Youth Policy Institute(NYPI) comprising 4,092 responses from 5th grade elementary school students and 4th grade(middle school 2nd grade) of elementary school students. The study data were subjected to hierarchical regression analysis to give the following findings. First, Levels of Multicultural Acceptability were significantly different. Second, factors influencing multicultural acceptability for elementary school students and middle school students were different. Common factors were mother's education level, life's satisfaction, peer relationship, teacher relationship, and spirit of community. Factors for elementary school students's multicultural acceptability were subjective academic achievement, community awareness, experiences of cultural activity, and overseas visiting experiences. The factor for middle school students's multicultural acceptability was family/group travel experiences. Our findings highlight the importance of programs and education that are suitable for children's developmental level. Such peer group programs need to be offered for middle school students to achieve spirit of community and educational group program and various extracurricular activities to achieve community awareness and develop a spirit of community for elementary school students.

Quality of life for people living with HIV/AIDS is significant as it concerns the treatment process, survival rate, HIV/AIDS prevention and treatment as well. Prevalent prejudice in our society significantly lowers the quality of patient's life. There is a need for an intervention and the effort to eliminate the stigma in order to lessen the negative effects as well. However, there are very few researches that examine the quality of life when it comes to people living with HIV/AIDS; even less when it comes to research that examines the stigma that affects the quality of life negatively. Therefore, this research seeks to verify the moderating effects of social support that seek to eliminate the stigma upon the quality of life in people living with HIV/AIDS. Research had been conducted with 102 people living with HIV/AIDS and the balancing effect of the social effort was verified through hierarchical regression analysis and a simple slope test. As the result of the research, control variables such as educational level and whether the patient has a job or not have significant effect and the stigma that the patient is aware of has significant negative effect. Social support had positive effect in quality of life and that it has a moderating effect on stigma which in turn affects the quality of life. Based on these results, social work related implications that were suggested are as follows; need for information and education as to better the quality of life for people living with HIV/AIDS and eliminate the social stigma and that group support program based on the local community which is needed for social support. Further research was advised based on the limitations of this research.

This study investigated population characteristics that influencing treatment service use of people who are voluntarily using drug dependency treatment services by using logistic and hierarchical regression analysis. The research model of the current study was driven by the framework of the 'the Behavioral Model of Health Services Use(the Andersen model)' that has been broadly applied to study on health behavior. This study used data from a sample group of 80 adults by using purposive sampling. This study found that some predisposing factors, enabling factors and need factors have direct effects on service use. In detail, individuals who graduated from high school use drug dependency treatment utilities more than those who did not. Further, individuals who were given more support from family, peers, or others, use the treatment utilities more frequently and were more willing to use the utilities continuously. Furthermore, the greater the perceived need felt by the dependent, the greater the tendency to enter hospitals or shelters. The important implications of this study for social work practice and social policy can be summarized as follows: first, this study supports the idea that intervention for drug dependents in Korea should be focused on environment resources rather than population characteristics; and government must support drug dependent treatment systems; the present study was the first to investigate Korean drug dependents through taking a more positive view, as well as the first to apply 'the Behavioral Model of Health Services Use', and as such represents an example of how studies could be productively conducted in the future. Despite these implications, there remain some limitations in this study. These include the following: limitation in generalizability of the results; the cross-sectional nature of the study design; survey research through the questionnaire method; using foreign scales; and the difficulty of classifying treatment settings.

This study draws on goal orientation theory and proposes the team learning goal orientation as an antecedent of team creativity. In addition, an Input-Process-Output (IPO) model was adopted, in which the team reflexivity, team efficacy, and positive group affective tone (PGAT) are linking mechanisms in the relationship between team learning goal orientation and team creativity. Using 57 teams from three lectures of the college, hierarchical regression analysis was conducted at the team level. The results showed that the team learning goal orientation had positive associations with team creativity, team reflexivity, and team efficacy. In addition, team reflexivity and team efficacy positively predicted the team creativity. Furthermore, the relationship between team learning goal orientation and team creativity was mediated by the team reflexivity and team efficacy. In contrast to predictions, PGAT did not show significant relations with both team learning goal orientation and team creativity. In conclusion, this study integrated the team-learning goal orientation and team creativity literature and contributes to the understanding of team reflexivity as a cognitive process and team efficacy as a motivational process between the team property and team creativity. These results have practical implications for managing teams.

Objectives : The purpose of this study was to find out how demographic factors, suicide attempt patterns, psychiatric history and management of suicide attempters affect the completion of emergency department (ED) based case management program. Methods : Among the patients who attempted suicide and visited the emergency department of Chung-Ang University Hospital from June 1, 2018 to May 31, 2021, 661 patients who agreed to case management were studied. After being discharged from the emergency department, subjects were registered for an eight-week follow-up service program. Hierarchical logistic regression analysis was conducted with demographic factors, suicide attempt patterns, psychiatric history and management as independent variables, and completion of case management program as dependent variables. Results : Suicide attempt pattern had the most significant influence on the completion of case management program, followed by demographic factors, psychiatric history and management. Those who completed the case management program were significantly more likely to have suicide plans in the future, more authentic in suicide attempts, and had higher proportion of past suicide attempts than those who did not complete the program. Conclusions : To ensure that the subjects complete the follow-up project program and get connected to community services, an individualized approach with consideration of suicide attempt patterns, demographic factors, and psychiatric history is needed.

Focusing on the potential impact of information and communication technology (ICT) on older adults' quality of life, this study empirically examined the influence of smartphone use in old age on life satisfaction, depression, social activity and social support of Korean older adults. In order to examine the effects of smartphone use, this study analyzed data from 630 questionnaire surveys from older adults aged 65 and over living in Seoul. The effects of smartphone use were tested using hierarchical multiple regression analysis, controlling for socio-demographic variables such as age, sex, spouse, education and income. Results showed that the effects of smartphone use on life satisfaction, depression and social activity of older adults were statistically significant. However, the effects of smartphone use on social support of older adults was not statistically significant. This study suggests that ICT such as smartphones in old age plays generally positive roles in enhancing psychological, mental and social aspects of quality of life. This implies that further practical efforts to expand the distribution and use of ICT in old age are required to improve quality of life and successful aging of older adults.

This paper analyzes the effects of government support systems, regulation, and innovation promotion policy on technological innovation performance of companies in the service industry using 4,000 Korean service industry companies. Multiple and hierarchical multiple regression analysis were used to analyze the correlation between the individual factors and process innovation and product innovation. Government support, regulation and technology innovation in the service industry were tested. In addition, government innovation promotion policy includes government support and regulation and the technological innovation performance of service firms. As a result, the government support system affects both the process innovation and the product innovation performance in the service industry, but affects only the process innovation performance in the case of regulation. Innovation promotion policy was found to regulate the relationship between government support systems and regulation and innovation performance of the service industry. Therefore, these findings provide strategic implications for the management of enterprises in relation to government support systems and innovation policy. It is necessary to reorganize regulations that are outdated to improve the effect of innovation policies on innovation performance.
