This study was conducted to compare of dietary behaviors of young and temporary workers with older and permanent workers of single-person households. A questionnaire survey was conducted by purposive quota sampling(n=566) by age groups(20~59 years old) and status of workers(temporary workers, permanent workers and business owners). Compared to other age groups, 20s had lower average monthly income and cost of eating-out, and they rarely cooked at home and mainly bought food and groceries at convenience stores(p<0.001). This pattern was similar to temporary workers compare to other groups. This study will be meaningful as a basic data for creating a healthy living environment for temporary workers and 20s of single-person households.

This paper examines the impact of a dual labor market structure on labor productivity using unbalanced panel data from 29 OECD member countries between 1990 and 2015. By applying a variety of regression models on the panel data (e.g., a pooled regression, a fixed effects model and a GMM), we explore how changes in worker-type composition among temporary, permanent and self-employed workers contribute to productivity growth. While it appears that our results differ slightly, depending on the econometric models, overall an increase in the share of permanent workers leads to a relatively higher increase in productivity growth. On the other hand, it is also seen that the effects of the share of temporary workers on labor productivity are considerably lower than that of permanent and self-employed workers. To sum it up, our findings indicate that an increase in temporary workers could have an adverse effect on labor productivity.

The purpose of this study was to investigate the job stress factors of aircraft composite material part manufacturing workers using survey based on 'Job stress factors evaluation tool for Koreans' that was developed by KOSHA in 2003. Two hundred and fifty workers participated in this study, and among them 204 responses were analyzed for this study due to the unreliability and insincerity of responses. The eight job stress factors which are physical environment, job autonomy, job insecurity, organizational system, workplace culture, unfair compensation, relationship conflict, and job requirement were analyzed. The results showed that the stress level of the six job stress factors which are physical environment, job autonomy, job insecurity, organizational system, workplace culture, unfair compensation was relatively higher than that of other industry workers. Generally, all eight job stress factors showed higher stress with temporary workers than with permanent workers, and especially job autonomy, job insecurity, organizational system, and unfair compensation factors showed statistically significant differences (p<0.05). Since the temporary workers are insecure with their job, weak position in organization, having little self-control for the job and lower pay level than that of permanent workers though the job is as same as permanent workers', the stress level of above job stress factors would be much higher than that of the other factors. The group of unsatisfactory with workplace showed higher job stress than group of satisfactory with workplace in all job stress factors, as expected, at the statistically significance level (p<0.05). From the results of this study, the work loss due to the job stress could be prevented, and accurate stress factors could be removed at the workplace. Also the job stress management program can be implemented to improve the work efficiency and the workers' quality of life.

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.

The purpose of this research is to identify the relation between OFDI (Outward Foreign Direct Investment) and wage inequality. In order to analyze various effects of OFDI on wages depending on the types of workers, the research classified laborers into four categories: permanent/skilled worker, permanent/unskilled worker, temporary/skilled worker, and temporary/unskilled worker. With controlling wage-determining factors such as education, labor union, individual fixed-effect, and industry-level effect, this paper examines whether OFDI attributes to the wage inequality among each type of workers. Moreover, this study also analyzes possible effects on wages that could vary according to the different characteristics of investments by classifying OFDI into two groups: OECD and non-OECD. The results reveal that OFDI makes certain differences according to skill-intensity and contract type in terms of influences on wages. It also shows that the effect of OFDI on wages is more subject to contract type than to skill-intensity. The classification of OFDI into OECD and non-OECD proves that effects on wages can vary by characteristics of the subject of investment.

The Swedish labor market secures flexibility in the use of labor force by means of non-regular workers such as temporary workers among others instead of regular workers' layoffs. Although the labor law reform in the late 2000s made it easier to use temporary workers and the outbreak of the economic crisis strengthened the power of user firms against labor unions, the size of temporary workers was scaled down. It is the aim of this study to analyze the change in the use of temporary workers, to examine the effect of the labor law reform and that of economic crisis in that regard, and to explain how, over the use of temporary workers, user firms' strategy to secure flexibility and labor unions' strategy to regulate flexibility interact with each other so as to establish a new equilibrium through conflicts and compromises. The labor law reform to enhance the flexibility in the use of temporary workers failed to entail amendments of collective contracts. Besides, out of the economic crisis, user firms adopted a new policy to use third party workers more, refraining from employing temporary workers. That's why the number of temporary workers has declined eventually. User firms prefer to use third party workers because they could avoid their own responsibility as an employer and they could rely on 'permanent temporary' workers without any time limit. Labor unions, however, responded with a strategy to lay more strict regulations on the use of third party workers, so that third party workers could be used only for limited cause for external numerical flexibility. As a result, the managed flexibility thesis comes to prevail to the usage of non-regular workers in general beyond the category of agency workers. Korea with severe abuse of third party workers should learn from Swedish labor unions' strategy to provide third party workers with stronger employment security and higher wages so as to prevent user firms from abusing third party workers.

Using Korean Labor and Income Panel Study data, this paper estimates nominal wage rigidity in Korea by industry from 2005 to 2017 and evaluates the level of inefficiency of Korean labor market. And, after estimating employment volatility by industry using the Labor Force Survey at Establishments data for Korea, we combine the nominal wage rigidity and the employment volatility estimates and analyze the effect of nominal wage rigidity on employment volatility in Korea from 2011 to 2017. If the level of wage rigidity is high, it may be hard for the labor market to be in the equilibrium, and therefore, the market may have inefficiency. We find that the inefficiency of the labor market in Korea have increased from 2005 to 2017 and the industry of accommodation and food service activities has the highest level of inefficiency over the period. We also find that one-percent-point increase in wage rigidity increases employment volatility by 2.3-2.9 percent and the positive effect is bigger for workers with part-time and temporary jobs. The result implies that firms may adjust their labor costs by changing the number of casual workers, rather than permanent workers, when the labor market suffers from a high level of wage rigidity.

To comparison of the differences in affecting factors of prevalence of obesity and hypertension according to the employment type of single-person households, aged 20 to 59 years old people were classified by permanent and temporary workers(n=566). A questionnaire survey was conducted by purposive quota sampling to ask disease, income and health habits. In the results of logistic regression on hypertension and obesity, the prevalence of hypertension was significantly affected as age and obesity increased regardless of employment type. In particular, temporary workers with lower income were more likely to have hypertension(p<0.001). The prevalence of obesity was significantly lower for female than for male regardless of employment type. In particular, temporary workers had a higher prevalence of obesity as their dinner fidelity decreased(p<0.001). As a result, chronic disease management for single-person households with lower income and dinner fidelity should be intervened in more useful ways.

This paper analyzed the effects of changes in temporary workers on firm performances, and the effects of different workforce portions of business functions on corporate performances, respectively, using Korean venture business survey conduected in 2013. Results show that the performance of venture businesses decreases significantly, as the portion of temporary workers increases, which is more pronounced in small companies than in medium companies. In addition, the portions of workforce for administration, R&D, production, and sales don't have uniform effect on firm performance, where medium companies are affected significantly by the portions of production and sales, while small companies do not show significant relationship. This analysis implies that innovative firms, based on knowledge workers, need to use caution when they plan to increase temporary workers, which may lead to lower performance. However, we need further research for the basic causes of the possible lower performance.

In this study we conducted a questionnaire survey by purposive quota sampling(n=566) by status of workers(permanent workers, temporary workers and business owners) and age group(20-59 years old) for single households engaged in economic activities in order to compare the health behaviors and health checking by employment type and age. By employment type, the sleep time of permanent workers was significantly less than that of other groups(p<0.001), and the rates of health and oral examinations in permanent workers were significantly higher(p<0.001). By age group, as the age increased, the oral condition was worse(p<0.001), but the rates of not taking oral examinations were significantly higher(p=0.023). This study can be meaningful as basic data for making a healthy living environment according to various characteristics of single households.
