The objective of this study is to investigate the healthcare status of South Korea and other member countries of the Organization for Economic Cooperation and Development (OECD) using OECD health statistics 2020. We employed the position value for relative comparison index to measure the healthcare status in five following components: demand, supply, accessibility, quality, and cost. The Mann-Kendall test was used to analyze for increasing or decreasing trend of the position value for relative comparison values from 2000 to the recent year. Results showed that Korea was positioned above than the OECD median values in most of components, but lower than the median values in certain indices including healthcare employment, primary care, and mental health care. This study sheds some light on healthcare issues to be improved and the policy-makes can take into account for prior setting process.

This paper deals with a comparison of individual and common grounding method for potential rise. When a test current flowed through grounding electrode, potential rise was measured and analyzed for grounding method using a electrolytic tank in real time. The grounding electrodes were designed and fabricated with ground rods on a scale of one-eightieth. Potential rises of individual grounding method were higher than those of common grounding method. The distributions of surface potential are dependent on the distance from grounding electrode.

The introduction of globalization has lead the marketing information systems(MkIS) to become a competitive weapon, since the MkIS are an important vehicle in the global market that supports firms in making decisions on the management of marketing-related activities. Yet there has been little investigation in Korea on the operation of MkIS. This paper replicates the research conducted in the U.S. on the operation of MkIS in the Korean environment, after a model on this operation is developed. Data were collected from firms in Korea, and research findings based on the analysis of these data were compared with those from the U.S. research. Based on this comparison, this paper suggestes a better way to address the problems Korean firms have and generates directions on future research in the operation of MkIS.

This paper reviews the performance difference between constant voltage control and constant current control in LED driver. Simulations of both control methods are performed for performance comparison especially with temperature variation. The results show that constant current control method is inherently better than constant voltage control for LED drive.

A system is designed and fabricated for the automatic low temperature calibration by comparison of industrial resistance thermometers. The cryostat is suitable for the calibration of four capsule type thermometers and four long stem thermometers. By the automatic temperature control of the cryostat, we could calibrate thermometers from $-200^{\circ}C$ to $0^{\circ}C$ for ${\sim}15$ hours by one fill of liquid nitrogen in the test run of the system. The uncertainty of the calibration for industrial platinum resistance thermometers using the automatic system is about 30mK with a 95.% confidence interval.

The Loss of a Main Feedwater Pump test at 100% Power for YGN 4 was simulated in order to verify and validate the KSNPA. The comparison of the test data with the KSNPA prediction results showed reasonable agreement in the trends of the major plant parameters. All plant control systems including NSSS and T/G control systems are properly actuated and stabilized the plant conditions to a new steady state conditions in the KSNPA. From the comparison results, the KSNPA showed its capability to simulate the LOMFP event for the Korean Standard Nuclear Power Plant.

Objectives: The purpose of the this study was to evaluate lifestyle intervention program for the treatment of the metabolic syndrome. Methods: Subjects of this study were 700 adults with metabolic syndrome who took health examinations in health promotion centers of Korea Association of Health Promotion between May 1 and June 30, 2006. Subjects were randomly assigned to an experimental group and a comparison group. Participants in the experimental group received intensive 3-month lifestyle modification intervention and participants in the comparison group received minimal information on lifestyle modification. Pre test and Post test were carried out to evaluate the effectiveness of the intervention program. Results: After the intensive intervention on lifestyle modification(healthy diet, physical activity, moderate drinking, stress management, and smoking cessation), the levels of blood pressure, waist circumference, fasting blood glucose and triglycerides were significantly reduced for those in experimental group(P<0.001). For those in comparison group, the levels of blood pressure(P<0.001), waist circumference(P<0.001), and triglycerides(P<0.01) were significantly reduced after the intervention. No change in the levels of high-density lipoprotein cholesterol were observed in both groups. After 3-month intervention, the prevalence of metabolic syndrome was reduced to 35.7% in experimental group and 48.5% in comparison group. Conclusion: This study has demonstrated the efficacy of therapeutic lifestyle intervention for the management of metabolic syndrome.

We devised calibration procedure for industrial thermometers by a comparison method at the boiling point of nitrogen (${\sim}-196^{\circ}C$). The uncertainty of the calibration was 4 mK (k = 2). As experimentally demonstrated in this work, the effect of the atmospheric pressure on the boiling point of nitrogen can be easily detected by the thermometer. Therefore, when the boiling point of nitrogen is used for calibration of thermometer by comparison, either a reference thermometer must be used to provide the reference temperature or the effect of atmospheric pressure should be carefully considered. The use of a copper block with a large thermal mass soaked into the liquid nitrogen was proven to be more reliable, and the stability of the temperature immersed into the copper block was 1.4 mK. The temperatures at the thermometer wells, evaluated by the crossed-measurement method to compensate for the inaccuracy of the thermometers and the linear drift of the temperature of the copper block, were equivalent within 0.23 mK of standard uncertainty.

This study analyzes the differences in definitions and concepts of terms used in the statistical indicators of fatal occupational injuries per 100,000 workers among countries included in the ILOSTAT data explorer. In addition, improvement measures focusing on the limitations in international comparison are proposed. Five countries-the Republic of Korea, Germany, Japan, United Kingdom, United States-- were comparatively analyzed. These countries were selected according to the significance of differences in their definitions of workplace injuries, workers, and compensation insurance, and their reporting systems. Considering these differences before directly comparing statistical indicators of fatal occupational injuries per 100,000 workers among countries is necessary because the range of comparison groups and the definition of fatal occupational injury are different for each country. While one can also compare trends by country, it is necessary to investigate beforehand whether the criteria and methods for processing statistics have changed. Misinterpretation can be minimized by properly understanding the process and limitations of fatal occupational statistical indicators that may differ from country to country.
