There have been so many studies related to job stress or musculoskeletal disorders(MSDs) in the shipbuilding industry. However, study of employee performance evaluation that reflect on the industrial features of the deckhouse manufacturing industry has not been established. Therefore, this study aimed to evaluate workers' job stress and work ability through statistical significance tests according to age, work types, years of service, work forms and sex. For this, the study conducted a job stress test using the Korean Occupational Stress Questionnaire Short Form, and employee performance evaluations using the Work Ability Index(WAI) of the Finnish Institute of Occupational Health (FIOH) on 536 workers in the deckhouse manufacturing industry. MINITAB statistics program was used for statistics analysis and significance was verified with the Kruskal-Wallis test, a corporate body of nonparametric statistical analysis. As a result, employee performance had significant differences, depending on age, work types, years of service and sex, and job stress also depended on the number of service year and work form. Additionally, it was found that employee performance decreased more as job stress increased.

Severities of musculoskeletal diseases (MSDs) have been recognized at the regular work such as manufacturing but incidence of MSDs are increasing also at the atypical work. The examples of those are health medical workers, office workers and service workers etc. Nurses among health medical workers are accomplishing to manage and recover the patients' health in the first place. Therefore, they are exposed to very stressful work conditions during caring the patients. This study was performed to analyze the musculoskeletal burdened work among nurses at a university hospital, in order to grasp the realities of the MSDs, analyze and prevent MSDs. We surveyed risk factors for ward, intensive care unit, delivery room, newborn room, operation room, function test room and central supply room at a university hospital in Seoul. It was executed for 2 months as the field study that was composed of simulation, real measurement, work motion assessment and subjective assessment. And the results were analyzed into ergonomics techniques. Works according to the criteria of musculoskeletal burdened work by the Ministry of Labor were scrub in operation room and heart ultrasonic function test. And a lot of works that need attention and management were also detected. So it should be required the education and systematic managements of MSDs for nurses.

Three types of zirconium base alloy were evaluated to study how their work hardening behavior is affected by alloy composition. Repeated-tensile tests (5% elongation at each test) were performed at room temperature at a strain rate of $1.7{\times}10^{-3}s^{-1}$ for the alloys, which were initially controlled for their microstructure and texture. After considering the yield strength and work hardening exponent (n) variations, it was found that the work hardening behavior of the zirconium base alloys was affected more by the Nb content than the Sn content. The facture mode during the repeated tensile test was followed by the slip deformation of the zirconium structure from the texture and microstructural analysis.

The purpose of this study was to investigate the stress from work and stress coping methods of hospital nurses. The study design was a descriptive survey research. There were a total of 168 hospital nurses included in this study. Data were analyzed by t test, ANOVA (Sheffe's test), and Pearson's correlation coefficient using SPSS/WIN17.0. The stress level from work was 4.27 and stress coping methods was 2.67. Marital status was positively correlated with education level, current department, career duration, and current position. The education level was positively correlated with career period and current position. Current position was positively correlated with stress coping methods. A further follow-up study on nurses in hospital is necessary to relieve stress from work and to increase better stress coping methods. Moreover, to decrease the stress from work of nurses, it is necessary to develop a program that helps them to cope with stress. In addition, these findings contribute to the development of such program.

This Study explores and describes the present status and effects of Korean social work ethic course , reflecting increasing concerns about social worker's ethics. Using the member list of the Council of Korean Social Welfare Education, this study first examines the extent to which the ethic course is established and how the course is managed. Then, for the purpose of investigating the practical effects of the enrollment in the ethic course, using the test scores designed to measure the students' sensitivity to ethical issues, this study compared test scores between students who attended the course and those who did not. This study also compared pre-post test scores of students who attended the course. The results show that enrollment in the course contributes to significant changes in the students' ethical sensitivities, in spite of social work education system that does not very yet empathize the ethics curriculum very strongly. Further, enrollment in the ethic course is proved to be a more powerful factor to ethical sensitivity than any other demographic or education related factors. These findings suggest a stronger emphasis abd serious consideration of the course, as well as more efforts to bring up professionals and invest in research in the field of social work ethic education.

Purpose: This study aimed to identify the mediating effect of Psychological stress of COVID-19 stress on the relationship between nursing work environment and turnover intention of nurses in long-term care hospitals. Methods: The participants were 176 nurses working at three long-term care hospitals in Changwon City. Data were collected from August 11 to 14, 2021, using self-report questionnaires. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and hierarchical regression, using the SPSS 23.0 software. A mediation analysis was performed according to the Baron and Kenny's test, and Sobel test. Results: Turnover intention was positively correlated with Psychological stress of COVID-19 stress (r=.23, p=.002) and negatively correlated with nursing work environment (r=-.44, p<.001). Psychological stress of COVID-19 stress had a significantly negative relationship with nursing work environment (r=-.15, p=.045). Psychological stress of COVID-19 stress partially mediated the relationship between nursing work environment and turnover intention. Conclusion: The findings of this study indicate that a positive nursing work environment can help nurses reduce their Psychological stress of COVID-19 stress and turnover intention. To reduce the turnover intention among nurses' in long-term care, it is necessary to promote better work environments suitable for COVID-19 and to establish detailed strategies for reducing their physiological stress.

The purpose of this study was to investigate the effect of police officers' participatory decision-making, supervisory quality and attitude, organizational justice on job satisfaction focused on mediating effect of work-life conflict. As a result of analysis of 185 police officers, the results were as follows. The causal relationships between participatory decision-making, organizational justice and work-life conflict, the ones between supervisory qualities and attitude, organizational justice, work-life conflict and job satisfaction, all of them reached the significance levels, not the causal relationship between supervisory qualityand attitude work-life conflict. Thus, the results for the interaction have shown, participatory decision-making and organizational justice and work-life conflict have negative influences on work-life conflict respectively, and supervisory qualities and attitude conflict, organizational justice conflict, work-life conflict have effect on job satisfaction with positive and negative effect. The Sobel-test showed that the Sobel-test statistic of the mediating effect of work-life conflict on causal relationships between organizational justice and job satisfaction is significant, but not in the mediating effect of work-life conflict on causal relationships between supervisory qualities and attitude and job satisfaction. According to the analytical results, work-life conflict is an important factor that can improve police officers' job satisfaction in the public organizational context with an open-oriented- system and culture for employees' participation in the process of decision making and equality and fairness for organizational management. It is also noted that work-life harmony for employees may be incompatible with the supervisor's perception of the work-oriented or prioritized-way in hierarchical organizations like police agencies.

Pullout test known as Lok test among the test methods to evaluate concrete strength strength is a test method which is used to decide the form removal time by assessing the early strength of concrete in a new construction, or to control the quality of newly placed concrete. This method has inconvenience to place inserts on the form work in advance, however, the placing work is quite simple and it has advantage that the strength can be measured at field as long as the inserts are placed. In this study, the first step is to investigate the properties of test method itself, by performing the laboratory test which covers deviation of the method and factors affecting the results, etc. The second step is to correlate the result with cylinder strength and other NDT methods such as rebound hammer, ultrasonic method, etc. And that, the results are compared with foreign results to find the differences between the two. In this research, new factors such as moisture content, area of aggregate failure cross section and area of aggregate separation cross section, etc as well as wate-cement ratio and age are investigated.
