  • Objectives : This study investigates the determinants of contingent workers' ratio in public health centers. Since the economic crisis in 1997, there have been many studies on contingent workers in Korea. But, previous studies have been not conducted focusing on public health center. Methods : This study used 253 public health centers, installed and operated since December 31, 2008. in Korea as units of analysis. To examine the determinants of contingent workers' ratio, this study uses Pearson correlation and multiple regression analysis. Results : The following appeared as significant variable affecting contingent workers' ratio in public health centers; degree of the local government's financial independence(p<0.001), rate of increase/decrease in ages 65 and over(p<0.001), rate of increase/decrease in basic livelihood security recipients(p<0.01) and rate of increase/decrease in registered disabled persons(p<0.01). In contrast, internal organizational environment characteristics related variables were not statistically significant. Conclusions : Contingent workers' ratio in public health center is significantly affected by financial vulnerability of the local government and increase in demand of health care services.

  • For evaluating the radiological safety of dismantled concrete, the process of disposal and recycling of the radioactive concrete generated during the dismantling of Kori Unit 1 is analyzed. Four scenarios are derived based on the analysis of the concrete recycling and disposal process, and the potential exposure to the workers and public during this process are calculated. VISIPLAN and RESRAD code are used for evaluating the dosages received by the workers and public in the following four scenarios: concrete inspection, transport of concrete by the truck driver, driving on a recycled concrete road, and public living near the landfilled concrete waste. Two worker exposure scenarios in the processing of concrete and two public exposure scenarios in recycling and disposal are considered; in all the scenarios, the exposure dose does not exceed the annual dose limit for each representative.

  • In recent years, Corporate Social Responsibility (CSR) has received particular attentions from both practitioners and scholars. This study focused on Korean national fashion businesses and identified various types of CSR practices in addition to social contributions. Besides, comparison in corporation by size of the number of full-time employees and sales volume were examined. A total of 1054 cases of 147 brands, 86 corporations between 2000 and 2012 were collected from internet articles and brand home pages. Findings were as follows. First, the types of CSR activities were categorized into the following six: economic responsibility, legal responsibility, consumer protection, protection of worker's right, protection of environment, and social contribution. Social contribution took largest portion of CSR activities (67.7%), followed by environmental protection (14%), and protection of worker's right (6.2%). The other three types presented limited cases but included negative aspects of CSR. Social contribution consisted of six sub categories (culture & art, sports, education, donation, voluntary service, and campaign), and donation took the largest part of social contribution area. Second, comparing 86 corporations by the size of the number of full-time employees, companies more than 300 employees (38.1%) were more likely to practice CSR activities. Similarly, companies with more than 500 billion won sales (13.1%) were more active in their CSR activities than their counterparts. Suggestions are given for improving CSR practices to fashion business.

  • Purpose: This study investigates the influences of coughing direction and healthcare worker's location on the transport characteristics of coughed particles in airborne infection isolation room (AIIR), which is commonly called negative pressure isolation room, with a downward ventilation system. Methods: Computational Fluid Dynamics (CFD) was used to simulate the airflow and for tracing the behavior of particles. Results: The results show that the airflow pattern and coughing direction have a significant influence on the characteristics of particle dispersion and deposition. When healthcare workers are in the isolation room with the patient who is lying on the bed, it is recommended to be located far from the anteroom to reduce the exposures from infectious particles. And when the patient is lying, it is more effective in removing particles than when the patient is in Fowler's position. Although it is an isolation room that produces unidirectional flow, coughing particles can spread to the whole room and a large number of particles can be deposited onto patient, bed, side rails, healthcare worker, ceiling, floor, and sidewall. Implications: Following the patients' discharge or transfer, terminal cleaning of the vacated room, furniture, and all clinical equipment is essential. Also, it is necessary to establish detailed standard operating procedure (SOP) in order to reduce the risk of cross-contamination.

  • Background: Kori unit #1 is permanently shut down after a 40-year lifetime. The Nuclear Safety and Security Commission recommends establishing initial decommissioning plans for all nuclear and radwaste treatment facilities. Therefore, the Korea Atomic Energy Research Institute (KAERI) must establish an initial and final decommissioning plan for radwaste-treatment facilities. Radiation safety assessment, which constitutes one chapter of the decommissioning plan, is important for establishing a decommissioning schedule, a strategy, and cost. It is also a critical issue for the government and public to understand. Materials and Methods: This study provides a method for assessing external radiation dose to workers during decommissioning. An external dose is calculated following each exposure scenario, decommissioning strategy, and working schedule. In this study, exposure dose is evaluated using the deterministic method. Physical characterization of the facility is obtained by both direct measurement and analysis of the drawings, and radiological characterization is analyzed using the annual report of KAERI, which measures the ambient dose every month. Results and Discussion: External doses are calculated at each stage of a decommissioning strategy and found to increase with each successive stage. The maximum external dose was evaluated to be 397.06 man-mSv when working in liquid-waste storage. To satisfy the regulations, working period and manpower must be managed. In this study, average and cumulative exposure doses were calculated for three cases, and the average exposure dose was found to be about 17 mSv/yr in all the cases. Conclusion: For the three cases presented, the average exposure dose is well below the annual maximum effective dose restriction imposed by the international and domestic regulations. Working period and manpower greatly affect the cost and entire decommissioning plan; hence, the chosen option must take account of these factors with due consideration of worker safety.
