This study reviews the trend of job separation rates for three years from 2002 to 2005 and investigates the various elements which influence this trend, especially the role of the labor unions, by using Korean Labor Panel data. In the basic statistics, the job retention rate of union members were higher by an average of 28.3% points compared to non-union members, but in the results of controlling the observed variables of individual influences in changing jobs, it was estimated that unions increase the job retention rate by 11% to 13% points. To investigate the effect of unions on the job stability of workers in detail, the non-linear decomposition method developed by Fairlie (2003) was used in the analysis. In examining the difference of job separation rates between union members and non-union members through observed variables of workers in explainable parts and unexplainable parts by using the non-linear decomposition technique, the contribution of the explainable part was estimated to be 67% to 74% and the unexplainable part accounted for the rest which was 26% to 33%. This suggests that not only does the union contribute to the job stability of its members, but the propensity to change jobs for a worker who is a union member is on average lower than that of a worker who is not a union member or who works at an establishment that does not have a union. The results of the empirical analysis show that the job stability effect of labor unions is limited within the boundary of a maximum 7% to 9% points. The reason for the effect of labor unions on job stability being so low is due to various reasons such as collective bargaining structure by company, intensified business competition after the financial crisis, and labor market segmentation.

Suicide is one of the major social problems in Korea, and its suicide rate is highest among the OECD countries. It has been reported that employment instability in labour market is causal factor of suicide ideation. Because the unemployed and temporary or part-time workers are reported to have high level of suicide ideation due to unstable job security, and they are likely to be a high risk group for suicide, it is necessary to do in-depth research on the effect of job stability on suicide ideation and the protective factors. For this purpose this study investigates the relationship between employment status and suicide ideation, and examine the moderating effect of family function. Data of 1,235 adults from the national-wide 'Longitudinal Study of Suicide Survivors' Mental Health were analyzed. Employment status were associated with the level of suicide ideation(B=-.904, p<.001), and the level of suicide ideation was the highest in the unemployed group. And the moderating effect of family function was statistically significant(B=-.218, p<.05), and good family function buffers the effect of unstable job status on suicide as a protective factor. Based on these findings, policy and practical implications for suicide prevention for precarious employment from the family dimension are discussed.

Taking 195 Korean businesses and sorting them out according to the unit types, this study looks into how flexibility strategy in labor market, which consists of numerical flexibility and functional flexibility, takes effect on the organization's outcome variable, which in turn consists of productivity, labor-management cooperation, and job security. In addition, the present study analyzes the role of labor union's moderating effect on the relationship among labor market flexibility, labor-management cooperation, and job security. It is found out as a result that numerical flexibility has no meaningful relation with productivity, labor-management cooperation, and job security, while functional flexibility has a considerably positive relation with them. This result confirms the importance of functional flexibility of business strategy in labor market. The West has continuously insisted the importance of functional flexibility, pointing out problems of numerical flexibility. On the other hand, considering that this study has confirmed functional flexibility's meaningful relation, while it has not found out numerical flexibility's negative relation, it is necessary to study further on the relationship between these two kinds of flexibility. The result of analysis on the role of union power's moderating effect confirms only the union power's interaction effect in the relation between numerical flexibility and labor-management cooperation. The possibility of union's opportunistic behavior can be detected in this result.

The foremost aim of the paper is to evaluate the flexibility and stability of the Korean labor market through a cross-country comparison with OECD countries. Evaluating by the OECD Employment Protection Legislation Index, the flexibility of permanent job layoff in Korea is close to the average of OECD countries. Employment of temporary workers appears to be relatively flexible allowing for effective indicators such as the proportion of temporary workers among paid employees. As regards security, the levels of job security, income security and combination security are all far below the OECD average. A panel data analysis of OECD countries reveals that labor productivity increases as regulations on permanent job layoff become looser and regulations on temporary employment become more rigorous.

This paper investigates how small-medium firms deploy organizational culture, job stability and environmental uncertainty for technological innovation(product and process innovation). This paper suggests that organizational culture has significant effects on technological innovation, that job stability and environmental uncertainty moderate relationship between organizational culture and technological innovation. To test the hypotheses, data were collected from small-medium firms. The survey data of 258 firms were collected and integrated as the empirical base for testing the hypotheses. Major results are as follows: Firstly, when organizational culture as well as control variables are considered, organizational culture had significant and positive effects on product innovation. This result implies that organizational culture is an important means by which small-medium firms can promote innovation. Secondly, the interaction between organizational culture and job stability had a positive and significant effects on product innovation. Thirdly, the interaction between organizational culture and environmental uncertainty had a positive and significant effects on product innovation and process innovation. This paper suggests implications and several future researches need to overcome the limitations of this paper.

The objective of this study is to verify the moderated mediating effects according to the severity level of a disability as well as the mediating effects of job security in the relationship between difficulties in the workplace of the disabled wage workers caused by the COVID-19 pandemic and their life satisfaction. As a result of analysis using SPSS ver. 25 and PROCESS macro, the difficulties within the workplace caused by the COVID-19 pandemic had a negative influence on life satisfaction through the job security of the disabled wage worker. In other words, it was revealed that the level of difficulties being faced by the disabled wage workers, which were caused by the COVID-19 pandemic, hinders their life satisfaction through job security. In addition, no moderating effect according to the severity level of disability was identified in the relationship between these variables. This is translated that difficulties in the workplace caused by the COVID-19 pandemic reduce job security and life satisfaction of the disabled wage workers regardless of the severity level of the disability. Based on the results thus far, this study further discussed the institutional implications for promoting the job security and life satisfaction of the disabled wage workers under the COVID-19 pandemic situation.

현재 국내 등명기는 대부분 국내 관련업체의 연구개발에 의하여 국산화 하고 있으나 LED 광원을 적용하는 기술 수분에는 해양선진국에 크게 미치지 못하는 상황이다. 특히 대형등명기에 LED 광원을 적용하는 경우 고출력 LED를 적용한 고용량 LED 광원을 사용하여 광량을 확보하여야 하며 이를 구동하기 위한 LED 드라이버모듈 개발이 필요하다. 또한 고용량 LED광원의 안정적인 구동을 위하여 고용량 LED 모듈의 모니터링 및 제어기술이 동반되어 개발되어야 한다. 이에 고출력 LED 모듈을 안정적으로 구동할 수 있는 LED 드라이버를 설계하고 LED 드라이버를 모듈화하여 안정적인 전원공급과 효율적인 제어가 가능한 LED 대형등명기용 LED 드라이버 모듈을 개발하고자 한다.
