This study aims to identify high exposure tasks among the tasks performed in domestic nuclear power plants as a basis for developing training programs to improve the efficiency of workers' work. To this end, we first analyzed the exposure status of radiation work in domestic nuclear power plants. Radiation tasks in nuclear power plants were categorized, collective doses were investigated, and the collective doses were calculated based on the collective doses, and representative high exposure tasks were identified. We found that the collective and individual doses in domestic nuclear power plants are continuously decreasing, but there is an imbalance of exposure among workers. In terms of work classification, nuclear power plants are managed in 236 work codes based on light water reactors and 181 work codes based on heavy water reactors, depending on the work equipment and location. Among the total work codes, 23 codes have an annual average dose exceeding 10 μSv, and based on this, 10 representative high exposure tasks were derived. The representative high exposure tasks were selected as S/G nozzle dam work, S/G debris removal work, nuclear instrumentation system, S/G eddy current detection work, and insulation work. The results of this study are expected to serve as an important basis for reducing the exposure of workers in nuclear power plants and improving work efficiency.

Companies that have suffered serious labor shortages are relocating their factories abroad where they can solve this problem by increasing the employment of foreign workers. Construction sites also employ foreign workers to supplement the scarce manpower, and the demand for foreign workers has been gradually increasing over time. Recently, based on discussions on whether or not to introduce foreign workers, the policy on the input of foreign workers into domestic construction sites has been shifted to exploring the actual input conditions and efficient management methods. In this study, we investigated the current status and input situation of foreign workers at the construction sites of the target area, analyzed the problems they posed from the manager's viewpoint, and derived a method of improving the utilization of foreign workers at construction sites. In order to proceed with this study, we surveyed the actual situation of the construction sites, which consisted mainly of foreign workers and domestic workers (managers), by investigating the construction sites, and conducted 1: 1 interviews to ensure the reliability of the survey. The data obtained from the survey were analyzed using the SPSS analysis program, and the response rate was analyzed for each item. As a result, various problems, such as institutional problems, communication problems, and quality deterioration due to malfunction, appeared. Therefore, this study derives an improvement plan for the efficient utilization of foreign workers by improving the institutional level related to their language education, wages and employment.

Recently, as Korean industrial structure is moving to the service job, the number of workers engaged in the service job is increasing slowly. According to the statistics by Ministry of Employment and Labor announced in June, 2013, the number of service job workers in Korea was 7,477,135 which accounted for 48.4% of total workers. The trend of this service job is expected to increase continuously in the future. According to the 2013 statistics by Ministry of Employment and Labor, the number of industrial accidents victims of industrial accidents in the service job was 30,526 which was the biggest number among the entire businesses. The victims in the service job accounted for 33.2% among the total number of industrial accidents and represented more than those in the manufacture and construction industry. The service job had various works and employment patterns and most service jobs are petty and are small-sized establishments and it is difficult to try voluntarily to prevent the industrial accidents. However, Korean occupational safety and health act was enacted in accordance with the construction and manufacture in which industrial accidents occurred frequently in the past. The support of the government for the industrial accident prevention is focused on the construction and manufacture. Therefore, the current service job is placed on the blind spot of the safety management. Raising the safety awareness of workers through the safety education is the most important in order to prevent the industrial accidents of the service job with many conventional/repeated disasters such as the conduction by a simple mistake. Accordingly, this study analyzed the features and accidents of the domestic service jobs through the literature survey and analyzed the institutional devices for the safety management of the domestic service job, and the safety management cases of foreign service jobs and compared with domestic systems. Considering demands for the basic safety education for service job workers, a questionnaire was conducted targeting the service job workers and the execution plan of the basic safety & health education targeting the service job workers was carried out through the brainstorming of trainers of worker in the service job.

The International Atomic Energy Agency (IAEA) proposes 11 industries that handle Naturally Occurring Radioactive Material (NORM) that are considered to need management. A water treatment facility is one of the above industries that takes in groundwater and produces drinking water through a water treatment process. Groundwater can accumulate natural radionuclides such as uranium and thorium in raw water by contacting rocks or soil containing natural radionuclides. Therefore, there is a possibility that workers in water treatment facilities will be exposed due to the accumulation of natural radionuclides in the water treatment process. The goal of this study is to evaluate the external radiation dose according to the working type of workers in water treatment facilities. In order to achieve the above goal, the study was conducted by dividing it into 1) analysis of the exposure environment, 2) measurement of the external radiation dose rate 3) evaluation of the external radiation dose. In the stage of analyzing the exposure environment, major processes that are expected to occur significantly were derived. In the measurement stage of the external radiation dose rate, a map of the external radiation dose rate was prepared by measuring the spatial radiation dose rate in major processes. Through this, detailed measurement points were selected considering the movement of workers. In the external radiation dose evaluation stage, the external radiation dose was evaluated based on the previously derived external radiation dose rate and working time. As a result of measuring the external radiation dose rate at the detailed points of water treatment facilities A to C, it was 1.90×10^-1 to 3.75×10⁰ μSv h^-1, and the external radiation dose was analyzed as 3.27×10^-3 to 9.85×10^-2 mSv y^-1. The maximum external radiation dose appeared during the disinfection and cleaning of activated carbon at facility B, and it is judged that natural radionuclides were concentrated in activated carbon. It was found that the external radiation dose of workers in the water treatment facility was less than 1mSv y^-1, which is about 10% of the dose limit for the public. As a result of this study, it was found that the radiological effect of external radiation dose of domestic water treatment facility workers was insignificant. The results are expected to contribute as background data to present optimized safety management measures for domestic NORM industries in the future.

Traditionally, foreign labor inflow into Korea has been rare and, hence, issues on foreign workers did not draw much attention. However, changing economic conditions of the Korean economy, such as "labor-shortage" problem in SMEs in manufacturing sector, has made the Korean government open its door to the foreign workers since the early 1990s through the Industrial Trainee System. The inflow of foreign workers, on the other hand, has generated various social and economic problems, such as substantial increase of illegal over-stayers, illegal utilization of foreign unskilled workers by domestic SMEs, to name a few. Against this background, the Employment Permit System was implemented from 2004. This new system aims at supplying foreign workers to SMEs as well as protecting them as legal 'employees'. In any case, it is very important to understand how and to what extent the inflow of foreign workers have affected the Korean economy in order to establish long-term policy stance. This paper aims to empirically assess the economic impact of foreign workers on domestic workers in the manufacturing sector during 1997~20001, focusing on the Industrial Trainee System. The empirical results of the paper can be summarized as follows. First, there is some evidence that male semi-skilled workers are the group that is likely to have been displaced by industrial trainees. Second, we were unable to find any strong evidence suggesting that the inflow of foreign industrial trainees decreased wages of less-skilled Korean workers.
