This study examined the moonlighting behavior in Korea, to which relatively less attention has been paid. Based on the wage earners of 25 to 65 year old married, the results show that about 1.4% of the sample have dual jobs, working very long hours, on average 60 hours for a week combining both the primary job and the secondary job. The results of the fixed effects logit model on the moonlighting participation indicate that the wage rate and the hours of work in the primary job have a negative effect on moonlighting participation while the insecurity of the primary job appears to lead to a higher probability of taking a secondary job. The results of the moonlighting hours analysis suggest that hours worked in the primary job have a negative effect on moonlight hours while the wage of the primary job does not appear to have any significant effect on moonlighting hours. Interestingly enough, the wage of the secondary job appears to have a negative impact on moonlighting hours, which might be very plausible considering the long working hours moonlighters are engaged in.

It is well known that the quality of job match has strong influence on the efficient allocation of labor resources in the economy on the macro level and also on the productivity of individual worker. Regarding this point we assumed that the selection of preferred job at the job entry can be interpreted as a subjective indicator of job match quality and tried to estimate the effects of such selection on the wage level. For this purpose we suggested random effects switching regression model and applied this model to the data of the Korea Labor Institute Panel Study from 1998 to 2000. As the results of estimation, we found that there exists large wage differentials at least more than fifty percent caused by such selection. Considering the fact that such wage differentials can not be suitably explained by the traditional reasons of the wage discrimination, we suggest the possibility that there also exists large productivity gap caused by the job mismatch and the necessity of improving the job placement service activity.

The purpose of this study was to investigate the influence of children's elementary school entrance to working conditions of employed mothers. The data from 4th to 8th wave of Panel Study on Korean Children (PSKC) were used for analysis. Specifically, we examined changes in wages, working hours and regular employment of employed mothers after their children entered elementary schools. We adopted Heck selection model for unbalanced panel data after controlling sample selection bias, and compare results of analysis for unbalanced and balanced panel data. The results showed that children's elementary school entrance reduces employed mothers' wage, working hours and regular employment. These results indicate that mother tend to leave regular job and could not entry into decent job when their children are in elementary school.

This study aims to examine the effect of discrimination experience on job satisfaction among working women with disabilities, focusing on meditating effect of self-esteem. To this end, the data from the 8th year of the employment panel of disabled population surveyed by the EDI; Korea Employment Agency for the Disabled was used for the study. The data collected from 549 working women of disabilities from EDI was analysed by using the path analysis. The findings are as follows: first, discrimination experience of working women with disabilities had a significantly negative effect of their job satisfaction. Second, self-esteem presented the mediating effect between discrimination experience and job satisfaction. Based on the results, this study proposed various programs to increase job satisfaction by enhancing self-esteem in situations where the experience of discrimination among women with disabilities is high and suggested practical implications to increase job satisfaction of working women with disabilities.

Social and economic polarization such as the collapse of self-employed people and job losses are becoming social problems due to the COVICD-19 crisis, and the role of social enterprises in providing social services to vulnerable people in various business sectors is very important. Social enterprises are complaining of difficulties in sustainability due to the hybrid nature of creating social value and economic value. Support for professionals matching the business sector of social enterprises is urgently needed for sustainability, but support for professionals is very insufficient due to insufficient budget. This study studied how specialized personnel affect the sustainability of social enterprises through the medium of social enterprise characteristics, indicating that specialized personnel affect the expansion and sustainability of the corporate main business sector. Based on the above findings, practical implications of social enterprise financial support projects were presented.

This paper aims at analysing what impacts the experience of self-employed business have had on the income mobility. Since 2000s, the flexibilization of labor market and the population aging led to the increase of the number of self-employed job as many retirees at the age of early 50s has set up the self-employed business as a bridge job. However, previous researches just have emphasized on the impoverishment of the self-employed, but not focused on what different effects the experience of self-employed had on the income class mobility by age group. This paper compares the difference in the income class mobility by age group and employment status, and analyses its longitudinal trends. According to the result, as a whole the experience of self-employed has positive effect on the upper mobility of income class, but it become disadvantageous for the upper mobility as the age goes up. When belonging to the age group over 60s, the experience of self-employed rather increases the risk of lowering income class. Just as the experience of self-employed has different effects on income class mobility by age group, so the differentiated measures for age groups are demanded.

This study has sought to analyze factors affecting work and work preference of older adults at national and individual level. A few theoretical hypotheses such as economic need versus job opportunity (or employability), attitude toward paid work, pull effect versus push effect were tested for citizens in eighteen OECD countries with International Social Survey dataset(2005) using multi-level analysis. Main findings are as follows. First, most older adults wanted to work regardless of the socio-economic status, which implies that non-work of older adults would be due to involuntary constraint rather than voluntary choice. Second, there existed class inequality in that the higher class tended to involve paid work more than the lower class did among 55-64 age group. Third, the push factor such as part-time employment ratio, rather than the generosity of social security, explained the work and retirement patterns better. In conclusion, at least from the comparative perspective, the main problem of older adults' work seems to be of labour demand rather than of labour supply, to be of labour market structure and work opportunity rather than of the pull factor.

This study tested the path model with regard to how certain variables (control attribution, demand-control-support of activity, and control strategy) affected the elderly workers' subjective well-being(swb). In the path model, the exogenous variables were internal and external control attribution. We used demand-control-support of activity, and primary and secondary control strategies as mediating variables. The endogenous variable was each elderly worker's swb. Study participants were 205 elders participating in an "education activity". We used descriptive statistical analysis, Pearson's correlation and hierarchical multiple regression to examine data collected from structured interviews with the participants. Path analysis revealed the followings: First, secondary control strategy was the strongest predictor of participants' swb but internal control attribution, demand of activity, and support of activity also positively affected participants' swb. Second, internal control attribution indirectly affected the participants' swb. Finally primary control strategy negatively affected on the participants' swb.

As ubiquitous technology develops, there are many studies to provide various contents proper to users through a mobile device. However, there is a limit of information provision due to a small user interface of a mobile device. This study proposes a system that can solve a problem and provide an intelligent agent model appropriate to a mobile environment and job information positively that an individual user is interested. It is composed of a personalization engine to monitor users' behavior patterns and a learning algorithm to provide information to a mobile device. Analysis shows that preferred job items are different by sex, age and education, while a region affects job searching significantly.

K. Suwab, a chairman of the World Economic Forum (WEF), reported the emerging of the $4^{th}$ industrial revolution by the convergence of artificial intelligence and robot as well as the fusion of true and virtual reality in the WEF 2016. He suggested the $4^{th}$ industrial revolution would change greatly the paradigm of industry and society in the future, and damage the security and quality of the human job severely. In this review the argument of terminology, the impacts on economics, industry technologies and jobs by the $4^{th}$ industrial revolution have been discussed. And the role of magnetics on the 2-4th industrial revolutions was reviewed briefly.
