The purpose of this study is to verify the effect of the compaction and virtue experienced by police officers in the organization on positive emotion and, second, to demonstrate the effect of positive emotion on the organization uniformity, which is subordinate variable. Third, we intend to verify the mediated effect of positive emotion in the relationship between compassion and organization uniformity, and fourthly, to demonstrate the coordination effect of collective self-esteem in the relationship between positive emotion and organization identicalness. Sampling of this study was conducted on 353 male and female police officers working at police stations belonging to the National Police Agency and used these samples for hypothesis testing. Studies have confirmed that the compaction and virtue experienced by police officers have a positive effect on positive emotion, and that positive emotion has a positive effect on the phenomenon of tissue co-ordination. And it has been shown that positive emotion plays a full role in the relationship between compassion, virtue and organizational co-ordination, and that positive emotion and collective self-esteem plays a controlling role in the relationship with organizational co-ordination. The theoretical implications of this study will contribute to creating a positive organizational culture by maintaining a strict hierarchical relationship and spreading the compaction and virtuous behavior to police organizations with high task stress.

This descriptive research investigates the knowledge of and attitude toward HIV/AIDS among individuals in their 20s to 40s. This study also analyzes the results of the 2011 and 2013 community health surveys to identify the factors influencing their knowledge and attitude. The study subjects were 20 to 49 years old, and the final analysis included 182,315 subjects. The collected data were analyzed through t-tests, ANOVA, correlational analysis, and multiple regression analysis. The survey results showed a high level of knowledge of HIV/AIDS, with 69.4% correct answers. Most individuals lacked knowledge regarding routes of infection, and those in their 20s had the lowest percentage of correct answers. As for attitude toward HIV/AIDS, 44.3% showed a negative attitude. The scores for knowledge and attitude toward HIV/AIDS were higher among males, unmarried individuals, individuals with a higher income, individuals with a higher level of education, individuals working in agriculture, forestry, or fishery, managers, professions that were not homemakers/unemployed, and professional soldiers. A positive correlation (r=0.27, p<0.001) was observed between knowledge and attitude. The factors influencing AIDS knowledge and attitude were gender, marital status, income level, occupation, and education level. This study confirmed that there is a difference by age group. As such, educational programs customized by age and other characteristics are expected to be more effective in enhancing knowledge and in developing a more positive attitude towards HIV/AIDS.

Purpose: A static loading test was performed to evaluate the ultimate flexural strength of a girder in which 80MPa high-strength concrete was synthesized on the compressive flange of the I-shape steel girder. Method: This test is designed and fabricated two types of specimens with different shear-connection specifications, and evaluated their ultimate flexural behavior until reaching the extreme event limit states. In addition, the ultimate strength was evaluated by comparing the test results and the results of the strain compatibility method. Result: By confirming the displacement within 0.02mm as a result of the relative slip measurement, it was verified that the two specimens secured perfect bonding. Therefore, the difference in the shear specification does not have a great effect on the stiffness, and if the specimens are completely synthesized, there is no difference in the behavior until it reaches the extreme-event limit states. Conclusion: The girder to be tested has a working load within the elastic range and meets the usability requirements for allowable deflection. Therefore, even if a part of the casing is subjected to the tensile force at the level of cracking, the deck will first reach the compression failure due to the role of the reinforcing bar.

This study is about the factors affecting organizational effectiveness and to suggest implications for encouraging organizational effectiveness. The conditional process model was analyzed with transformational leadership as an independent variable, educational service quality as a mediator, organizational effectiveness as a dependent variable, and trust as a moderator. The data collected from the financial institutions were analyzed using SPSS v22.0 and PROCESS macro v3.4. As a result, transformational leadership has a (+) effect on educational service quality, and educational service quality has a (+) effect on organizational effectiveness. Except for the relationship between charisma and innovative behavior, transformational leadership affect organizational effectiveness. Excluding the relationship between charisma and innovative behavior, educational service quality mediate between transformational leadership and organizational effectiveness. Trust only moderates between educational service quality and innovative behavior. Trust moderated the mediating effect of educational service quality between transformational leadership and innovative behavior. The results suggest the importance of education service quality management in a non-face-to-face working environment and the importance of individual consideration in innovative actions.

Limit state design (LSD) and allowable stress design (ASD) are two main types of soil nailing design methodologies. In the LSD method, stability is determined by applying individual coefficients to ground strength, working load and etc. The ASD method calculates the safety factor and compares it with the minimum safety factor to determine the stability. The global design trend of soil nailing system is changing from the ASD method to the LSD method. The design method in Korea still adopts the ASD philosophy while others mostly do the limit state design. In this study, four soil nail design methods, 'FHWA GEC 7' in U.S. (2015), 'Clouterre' in France (1991), 'Soil nailing - best practice guidance' in U.K. (2005), 'Geoguide 7' in Hongkong (2008), and 'Design guide for slope in construction work' in Korea (2016) were applied to the evaluation of the stability and the results were analyzed comparatively in brief. It is revealed that the design method of 'the overall stability of soil nail walls' in Korea is the most conservative and next those by FHWA, Clouterre and CIRIA become more conservative in order. However, the difference of results obtained from FHWA and Clouterre is negligible. Also, this study found out that efforts to improve domestic design criterion are needed.

This study examined the relationship between job stress and fatigue symptom of fire-fighting officials. The study subjects were 330 fire-fighting officials working at five fire stations in the D metropolitan city. The study survey was a structured self-administered questionnaire from September 1 to October 31, 2019. The level of fatigue symptoms and job stress were significantly higher (p<.0.001). By the sub-region, the level of fatigue symptoms and job demand were significantly higher (p=0.046), but the decision latitude, the supervisor support, and co-worker support were lower (p=0.006, p<0.001, and p<0.001, respectively). The level of fatigue symptom showed a significant positive correlation with the total score of job stress (r=0.348, p<0.05) and the job demand (r=0.301, p<0.05). In contrast, it showed a significant negative correlation with the decision latitude (r=-0.306, p<0.05), supervisor support (r=-0.340, p<0.05), and co-worker support (r=-0.355, p<0.05). Multivariate logistic regression showed that the odds ratio of the high-risk fatigue group was significantly higher in the high-risk group of job stress than in the low group of job stress (ORs=3.03, 95% CI=1.13~8.12). These findings suggest that the level of fatigue symptoms of fire-fighting officials is related significantly to job stress.

The purpose of this study was to examine the relationships between job stress, life satisfaction, burnout, and self-compassion. A survey was conducted in February 2018 for employees working at the Korea Legal Protection and Welfare Agency, and 213 data were included in the final analysis. A structural model was developed to examine the relationships between the variables used in this study, and the model-fit and mediating effects of the developed model were examined using SPSS and AMOS. For this study, the Korean occupational stress scale, life satisfaction scale, Maslach burnout inventory, and Korean self-compassion scale were used. We found that self-compassion is fully mediated between job stress and life satisfaction and between job stress and burnout. Also, life satisfaction is partially mediated between self-compassion and burnout. These results mean that self-compassion has significant effects on job stress, life satisfaction, and burnout. In particular, the mediating effect of self-compassion shows the vicious cycle of high job stress - low self-compassion - low life satisfaction - high burnout. Based on these results, the future implications of program development based on self-compassion strategies were discussed in order for workers in correctional facilities to decrease job stress and burnout and increase life satisfaction.

Due to the rapid demographic and structural changes, Korea has faced a variety of social issues and quickly entered the aged society since the 2000s. In order deal with this reality, diverse types of welfare policies are emerging in the society as a whole. The government began to supply domestic public silver housing in 2016 to provide against the quickly growing aged society and now, the government is planning to supply approximately 50,000 housing by 2022 for quantitative growth of aged society, by selecting 1st and 2nd designated areas for the project additionally. This public retirement(silver) housing combines 'space' with 'service'. The lower floors are a public silver welfare Facilities and the upper floors are a housing spaces. This type of housing is to deal with requirements of rental housing residents by combining physical space with supporting service. Based on barrier-free design, the complex and unit house have safety handles and alarm bells in the bathroom, undulating washstands, bathroom sliding doors, corridor safety handles, and emergency safety exit lamps in each housing unit so the aged and the disabled can use easily and conveniently. Also, hand rails are installed and stepped pulleys are removed to promote convenience. Currently, the government is planning to increase the supply, focusing on low-income groups, such as beneficiaries of national basic livelihood and the working poor. Recognizing that the public retirement(silver) housing project is at its early stage, this study examined satisfaction, based on evaluations of real residents. This study aimed to obtain more empirical research data and apply them to public retirement(silver) house space analysis. For analysis, this study targeted Wirye public retirement(silver) housing and Magnolia public retirement(silver) housing that are in operation, and literature review, previous research review, and field survey were conducted to examine the present state. Using the questionnaires consisting of four large classification items; Block Layout, Housing Unit, Welfare Facilities, and Barrier-free Design, and sub-details, a survey was conducted to analyze residents' satisfaction. In conclusion, it is anticipated that this study would serve as basic research data about public retirement(silver) housing to increase continuously in future by analyzing public retirement(silver) housing spaces, on the basis of the analyzed data.

Due to the change in the demographic structure, the problem of low birth rate and aging population leads to a serious decrease in human resources, and the necessity of introducing foreign workers is increasing. This study believes that the introduction of foreign workforce is the most effective to expand the working-age population in the era of low birthrate and aging, when demographic changes begin in earnest, and to this end, it sought to devise measures to improve the legal system for migrant workers. As a result of this study, first, the legal system for migrant workers should be unified and improved. It is necessary to establish or unify management agencies so that the 「Immigration Control Act」 and the 「Labor Act」 can establish a cooperative relationship. Second, the 「Immigration Control Act」 should be revised to make it easier for migrant workers to find employment. It is necessary to positively review the employment permit system and acquisition of nationality. Third, there should be no equity or discrimination against migrant workers. Under the principle of mutual benefit, employers and migrant workers should not be equally discriminated against. Fourth, the social insurance system must be added to the legal system of migrant workers. Therefore, the legal system should be reorganized so that migrant workers are not discriminated against in various insurance systems including the four major social insurance systems. In conclusion, the problem of low birthrate and aging population has become a serious social problem due to changes in the demographic structure, and the decrease in the possible generation population has reached a level of concern. The importance of migrant workers' employment and work environment is increasing. Nevertheless, related legal and institutional problems still exist, and measures to improve the legal system for migrant workers are needed.
