In this paper, the dynamic behavior for a group of transmission towers linked together through electrical wires and subjected to a strong ground motion will be investigated in detail. In performing the seismic analysis, the wires and the towers concerned are modeled, respectively, by using the efficient cable elements and the 3-D beam elements both considering geometric nonlinearities. In addition, to enhance the reliability and applicability of analytical outcome, a sophisticated soil-structure interaction model will be utilized in analyses. The strength capacities and the fracture occurrences for the main members of the tower are examined with the employment of the appropriate strength interaction equations. It is expected that by aid of this investigation, those who are engaged in code constitution or in practical designing of transmission towers may gain a better insight into the roles played by the interaction force between towers and wires and by the configurations of transmission lines under strong earthquake.

This study concerned with the characteristics and causes of musculoskeletal disorders (MSDs) for employees aged 50 years or older. In order to do this, based on 8,011 accident analysis reports, we analyzed the differences of characteristics between groups under 50 years and 50 years or more in terms of gender, occupation, duration of employment, part of body, industry, size of business and work-related factors. Results show that the distributions of the injuries aged 50 years or older are statistically different from those of the injuries under 50 years. Also, older employees have high relationship between repetition, or contact stress/vibration and upper extremity MSDs. These findings can be used to develop more effective MSD prevention programs for older employees.

This study examined risk factors and protective factors in high school students’ suicidal ideation. Participants were 2000 adolescents from the KEEP(Korean Education and Employment Panel). Data mining decision tree model revealed that: (1) Irrespective of sex, the most important predictor was father-adolescent relationship. (2) Positive mother-adolescent relationship was predicted as protective factor in condition of negative father-adolescent relationship. (3) Family activities was predicted as risk factor in condition of negative mother-adolescent relationship under the circumstances with negative father-adolescent relationship. (4) Low self-evaluation was predicted as risk factor in condition of serious agony about personality under the circumstances with positive father-adolescent relationship.

The Employment Permit System (EPS), a system of bringing in low-skilled foreign workers, has been implemented since 2004 to relieve labor shortages in SMEs. Despite the increasing number of foreign workers under this system, due to lack of research we have very limited managerial understanding. Moreover, previous studies focused on economic or legal perspectives, which calls for a different perspective of business and management. In this study, we examined how to foster organizational citizenship behaviors (OCB) of low-skilled immigrant workers at the workplace by integrating two analytical frames-social support from management studies and cultural adjustment from immigrant literature. We tested our model using a sample of 661 immigrant workers from 11 countries working in Korea. Our results indicated that, social support perception triggered not only a direct effect on organizational citizenship behaviors of immigrant workers but also indirect effects via the level of cultural adaptation. Our findings indicated that two views are all meaningful in explaining OCB of immigrants, and provided practical implications to SMEs using EPS.

The importance of selection methods of secondary school teachers have gathered attention due to their enormous influence on the pre-service education programs. However, scholars and practitioners are skeptical about the effectiveness of the measures, especially under the condition of teacher oversupply found in South Korea and China. Based on this problem statement, this study seeks to compare the secondary teacher employment methods of the two countries to better understand the situations as well as to draw implications for improvement. We reach the following conclusions through comparative analyses. First, the reforms of the teacher employment system in both countries have been triggered by the quantitative supply concerns not by the qualitative concerns. Second, both countries require teaching license as a precondition of employment, while their quality assurance measures for the license reveal critical limitations. Third, both countries have attempted to improve selection methods; nevertheless, oversupply of prospective teachers makes objectivity and fairness more important than the appropriateness. Based on the conclusions, policy implications focusing on the quality-oriented approach are suggested in order to employ effective secondary teachers who can contribute to the quality improvement of school education.

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.

One of the current issues in Workers' Compensation Insurance is about the coverage range. Korea uses the definition of worker under the Labor Standards Act in Workers' Compensation Act and solved the problems associated with the coverage range of insurance group by the exceptional clause only for the groups which was raised about the need for the social protection. The purpose of this paper is to draw implications for solving problems which are associated with the coverage range of insurance group by reviewing the German literature. We focus on volunteers and persons in special types of employment. German government supports the activity of volunteers by providing with the protection service against the accidents. This paper shows how the coverage range is extended from the dependent employees in the introduction of the Workers' Compensation Insurance to the people who need social protection focusing on the volunteers. The implications of this research are following. First, German system shows that Workers' Compensation Insurance can be extended to the groups which do not belong to the dependent employee but are worthy of protection. Second, it is necessary to provide volunteers in the social welfare system with the protection service against the accidents and the statutory accident scheme is recommendable to use. Third, volunteers in the social welfare system need to be compulsory insured. Fourth, Korea should find their own way in solving problems associated with persons in special types of employment.

This paper considers a heterogeneous agent dynamic general equilibrium model and analyzes effects of an increase in labor income tax rate on labor market and the aggregate variables in Korea. The fiscal policy regarding how the government uses the additional tax revenue may take the two forms: 1) general transfer and 2) earned income tax credit (EITC). The model features are as follows: 1) Workers are heterogeneous in their productivity. 2)Labor is indivisible, hence the analysis focuses on the variation in labor supply through the extensive margin in response to a change in fiscal policy. 3) The incomplete markets are introduced, so individual workers can not perfectly insure themselves against risks related to stochastic changes in income or employment status. 4) The model is of general equilibrium, hence it is equiped to analyze the feedback effect of changes in aggregate variables on individual workers' decisions. In the case of general transfer policy, the government equally distributes the additional tax revenue to all workers regardless of their employment states. Under this policy, an increase in the labor income tax rate dampens work incentives of individual workers so that the aggregate employment rate decreases by 1% compared with the benchmark economy. In the case of EITC policy, only employed workers whose labor incomes are below a certain EITC ceiling are eligible for the EITC benefits. Unlike the general transfer policy, the EITC induces low-income workers to participate the labor market to be eligible for EITC benefits. Hence, the aggregate employment rate may increase by 2.7% at the maximum. As the EITC ceiling increases, too many workers can collect the EITC but the benefits per worker becomes too little so that the increase in employment rate is negligible. By and large, this study demonstrates that EITC may effectively raise the aggregate employment rate, and that it can be a useful policy tool in response to the decrease in the labor force due to population aging as observed in Korea recently.
