In this study aims to research and analyze what are decision factors between a wholly-owned subsidiary and a international company cooperation in the internationalization process. From 57 primary studies found 26 observed variables for aggregation of effect size in the using "Fixed Effect Model" on this mata-analysis. The article also links the theories that are used in the literature, not considered in the most of primary studies, to the empirical results and recommends global management strategy which is needed for business practical affairs. According to the result, the meta-analysis suggests that the number of employees of a MNC, the geological and cultural differneces between the host country and home country, the country-specific international experience of the MNC and export intensity, the international product diversification, the market growth and the market size of the foreign operations, and resource intensity of the foreign operations, the legal restrictions in the host country and the country risk of the home country do exert a significant effect on the decision between cooperative arrangement and a wholly-owned subsidiary. Conversely, for a large number of variables, no significant relationship seems to exist based on the combined results. This is the case, for example, for factor specificity, the r&d-intensity, the subsidiary size, the assets of the MNC and the sales volume of the MNC.

This study investigates the risks that can occur during the development stage of IPP project in developing countries. In case that ECA and MLA cannot participate due to poor credit rating of the country, the diversification of power purchaser in marginal states can be a great help to reduce both market risk and country risk at the same time. In case of thermal power plants and combined cycle power plants, the effect of performance degradation as time passed will be considered and expected profit of sponsors should be maintained. Recently, developing countries are expanding IPP projects to reduce the financing cost and Korean power companies are positively participating in IPP projects. Accordingly, the loss of Korean companies should be minimized by risk management through the risk mitigation methods of this study.

Background: The Republic of Korea has a very low prevalence of human immunodeficiency virus (HIV) infection, but the number of new HIV diagnoses has steadily risen, strongly indicating a large number of undetected HIV infections. Thus, it is important for Korean public health authorities to adopt and encourage cost-effective HIV detection tools, such as rapid HIV screening tests. In this study, we aimed to evaluate the cost-effectiveness of enzyme-linked immunosorbent assays (ELISA) and rapid tests in a public health center (PHC) setting. Methods: We developed a decision analytic model to assess the per-examinee cost and the cost-effectiveness of identifying HIV patients in a PHC setting using two HIV testing strategies: conventional HIV screening by ELISA versus rapid HIV testing. Analysis was performed in two scenarios: HIV testing in an average-risk population and in a high-risk population. Results: Compared to the ELISA, the rapid test was cost-saving and cost-effective. The per-examinee cost was USD 1.61 with rapid testing versus USD 3.38 with ELISA in an average-risk population, and USD 4.77 with rapid testing versus USD 7.62 with ELISA in a high-risk population. The cost of identifying a previously undiagnosed HIV case was USD 26,974 with rapid testing versus USD 42,237 with ELISA in an average-risk population, and USD 153 with rapid testing versus USD 183 with ELISA in a high-risk population. Conclusion: Rapid testing would be more cost-effective than using conventional ELISA testing for identifying previously undiagnosed HIV-infected cases in Korea, a country with extremely low HIV prevalence.

Objective : Low back pain (LBP) is a global health problem that affects the productivity of the patients. Several factors such as individual, occupational, and psychosocial factors increase the risk of LBP. However, only a few studies investigated those factors, especially in middle adulthood in Indonesia. Indonesia is a country with a young population that has been rapidly developing in recent years. This study was conducted to find out the factors associated with LBP in middle adulthood. Methods : This study is a cross-sectional observational analytic study using a convenience sampling method with a total sample of 3005 respondents. Data were collected using a questionnaire which was then analyzed using the chi-square test, Kolmogorov-smirnov, Spearman's Rank, and logistic regression test. Results : From the result of this study, it was found that the 12-month prevalence of LBP in middle-aged adults was 44,29%. Female (odds ratio [OR], 1.3; 95% confidence interval [Cl], 1.098-1.545; p=0.002), lack of physical exercises (OR, 0.87; 95% Cl, 0.794-0.959; p=0.005), high body mass index (OR, 1.09; 95% Cl, 1.009-1.187; p=0.002), stress level (OR, 1.26; 95% Cl, 1.088-1.458; p=0.002), and years of work experience (OR, 1.1; 95% Cl, 1.001-1.225; p=0.047) were determined as risk factors that significantly associated with LBP. Conclusion : LBP is quite common among middle-aged adults in Indonesia. Female gender, higher body mass index, lack of physical activity, stress level, and years of work experience were all potential risk factors for LBP in middle-aged adults. Middle-aged adults in Indonesia should be aware of LBP and avoid disabilities by identifying risk factors that may worsen LBP in the future.

Biotech crops can only be commercialized after they receive safety approvals, which require thorough risk assessments of their release to the environment. Environmental release experiments are indispensable for environmental risk assessments, and each country has been preparing its own regulations for the safety management of experiments on the environmental release of biotech crops in confined fields. In this study, we compared and analyzed the safety management regulations of the environmental release of biotech crops in Korea, USA, Japan, European Union, and China. Each country had safety management regulations for the environmental release of biotech crops, and these regulations were generally not much different from the Korean regulations. However, there was a difference amongst the USA, Japan, and China in regulations for isolation distances to prevent gene diffusion through pollen-flow during environmental release experiments of biotech crops. In order to establish the isolation distance regulation suitable for the Korean environment, relevant data were collected and presented. For setting the isolation distance for environment release of biotech crops, it is suggested to refer to the isolation distance information provided in the Guidance of Seed Management in Korea. The results of this study are expected to help establish the safety management of biotech crops in Korea.

Background: Over the last decade, medical tourism industry has grown in Korea. Especially the number of Mongolian medical tourists has increased rapidly. Therefore, the Mongolia is one of the targets for Korea medical tourism. The purpose of this study is to investigate the effects of destination image and expected attributes of medical services on Mongolian's intention to use Korean medical tourism service. Methods: This study empirically collected survey data from Mongolian lived in Mongolia. The study analyzed the data using a PLS model. Results: Our results are as follows. First, the country image didn't significantly have causal effects on expected medical service quality and perceived risk. Second, tourism image (e.g., entertainment, economic feasibility, and local convenience) has significantly causal effects on expected medical service quality and perceived risk. However, tourist site as tourism image didn't significantly have causal effects on expected medical service quality and perceived risk. Third, medical image made a statistically significant effect on expected medical service quality and perceived risk. Fourth, the expected medical service quality showed a significant effect on intention to use Korean medical tourism service. Fifth, the perceived risk of medical tourism showed a significant effect on the reliability of medical tourism, but didn't show a significant effect on the intention to use Korean medical tourism service. Finally, the reliability has a significant effect on the intention to use Korean medical tourism service. Conclusion: From our empirical results, this study concluded that as a strategy attracting Mongolian patients, it is more effective to strengthen Korean hospital image and tourism image than Korean country image.

Background: Evidence on associations between occupational diesel exhaust and gasoline exposure and colorectal cancer is limited. We aimed to assess the effect of workplace exposure to diesel exhaust and gasoline on the risk of colorectal cancer. Methods: This case-control study included 181,709 colon cancer and 109,227 rectal cancer cases diagnosed between 1961 and 2005 in Finland, Iceland, Norway, and Sweden. Cases and controls were identified from the Nordic Occupational Cancer Study cohort and matched for country, birth year, and sex. Diesel exhaust and gasoline exposure values were assigned by country-specific job-exposure matrices. Odds ratios and 95% confidence intervals were calculated by using conditional logistic regression models. The results were adjusted for physical strain at work and occupational exposure to benzene, formaldehyde, ionizing radiation, chlorinated hydrocarbons, chromium, and wood dust. Results: Diesel exhaust exposure was associated with a small increase in the risk of rectal cancer (odds ratio - 1.05, 95% confidence interval 1.02-1.08). Gasoline exposure was not associated with colorectal cancer risk. Conclusion: This study showed a small risk increase for rectal cancer after workplace diesel exhaust exposure. However, this finding could be due to chance, given the limitations of the study.

This Analyzed case study of measuring displacement, implemented laboratory investigation, and in-situ testing in order to interpret ground subsidence risk rating by excavation work. Since geological features of each country are different, it is necessary to objectify or classify quantitatively ground subsidence risk evaluation in accordance with Korean ground character. Induced main factor that could be evaluated and used to predicted ground subsidence risk through literature investigation and analysis study on research trend related to the ground subsidence. Major factors of ground subsidence might be classified by geological features as overburden, boundary surface of ground, soil, rock and water. These factors affect each other differently in accordance with type of ground that's classified soil, rock, or complex. Then rock could be classified including limestone element or not, also in case of the latter it might be classified whether brittle shear zone or not.

Recently, domestic construction companies have been moving towards overseas markets due to decreasing orders and an increase in competitiveness within the domestic market. However, there is a higher risk involved in the overseas construction Industry than in the domestic construction industry. Especially, because domestic construction companies lack development's experience, such a companies have a weakness of hidden risk factors. For Overseas New Town development project's success of domestic construction companies, preferentially, It Is necessary to deduce and analysis of risk factors in real estate development phases. This study would possibly be able to provide the preliminary data for Overseas New Town development projects in the future.
