Objectives : The recognition rate for issues and improving resolution for the recuperation income expense claim policy was examined. Methods : 1,135 copies of survey have been sent to the group of people who have claimed the dental recuperation income expense to dental recuperation institutions in Daejeon, Chungcheong Do that are registered to the health insurance evaluation and estimation office as of the May 2010 and 207 surveys that were regarded to be sincere for answering were analyzed. Results : Majority of respondence were belonged to the dentist institutions with more than 5 years of claim experiences as well as 10~50% of claim rate. The recognition of medical fee evaluation guideline was normal level, and negative recognition was higher to the health center with daily charge policy compare to the dental hospital and university affiliated dental center with treatment charge policy, Highest opinion for inappropriateness of dentist with significance was found (p<0.05). The openness of evaluation cases are regarded to be discharged through the transparent evaluation and most of the opinions for insurance claim evaluation adjustment are within the both 'Do not understand the evaluation guideline and program error of disease category, code and program' with significance(p<0.05). The reaction after the evaluation adjustment was high in reflection on the claim process after examining the reason for the evaluation adjustment through the evaluation and estimation office and university affiliated dental institution and dental center was regarded to be most active and deputy reclaimment was seemed to be most actively discharge the objection registration task (p<0.05). The claim error improving resolution recognition was highly prioritized to the accurate charting for the disease title and treatment description, improving the setting of claim program, and most highly recognized by the university affiliated dental hospital/dental center and comparably low by health center(p<0.05). and although the most of the responds of treatment description and browsing the medical fee was positive, 50% of dentists disagreed the idea so that this was creating a significant discrepancy with other groups(p<0.05). Conclusions : From this research, the recognition of medical fee evaluation guideline for dental (university) hospital and dentists were negative and high adjustment experience was examined as lacking of evaluation guideline understanding and error of disease name, code and programs and deputy reclaimment, university affiliated dental hospital/dental center were most actively handle the objection registration tasks and dentists have objection on the treatment description and browsing the treatment fee so that if these indexes can be referred to implement into the recuperation income claim process, this can be regarded to be a opportunity to create mutual credibility between recuperation institution, treatment pensioner and the evaluation institutions.

This article examines social determinants of population health in OECD countries, where life years, infant mortality, and PYLL are used as proxy variables of health. The unit of analysis is a country which is the OECD affiliate. A panel regression estimation is chosen as a method, using OECD Health Data. The results are: the increasing national health expenditure affected positively to improve population health. Education was rather a significant determinant of health than income level. The government direct investment for public health did not contribute positively to enhance population health. The expansion of health care coverage was working positively for improving health, but with a time lag. The supply of doctors was a most influential determinant of health. In case of Korea, the coverage expansion of health care was the most important determinant of health. The supply of doctors was, however, not a positive factor for better health, which is different result with the case of OECD countries.

The purpose of this study is to analyze the effect of the R&D subsidies by the government on the private firms' R&D investments in the Korean pharmaceutical industry, which are supposed to have positive effects on their economic performance. We also estimate the relationship between the private firms' R&D investments and firms' economic outcome. Empirical analysis is done by Error Component 2 Stage Least Squares(EC2SLS) estimation using 43 pharmaceutical firms' 8 years' panel data. The elasticity of the government R&D subsidies on the private R&D investments is 0.021%, which we cannot say 'efficient'. Also R&D investments have positive effects on the economic outcome of the pharmaceutical firms, as we expected. We propose several suggestions in the conclusion for the efficient way of government R&D subsidies to induce more private R&D investments.

본 연구는 비안정적 시계열 자료 분석 방법을 이용하여 장단기 고용탄력성을 추정하고 그 변화를 고찰하였다. 그 결과, 지난 25년간 고용탄력성이 유의하게 감소했다는 증거를 발견할 수 없었다. 이는 외환위기 이후의 취업자 수 증가율 감소가 고용탄력성 감소보다는 성장률 감소에 크게 기인함을 의미한다. 그러므로 일자리 창출력을 높이려는 정책적 노력은 성장잠재력 강화에 경주되어야 한다. 통계적 유의성을 떠나 고용탄력성 감소경향을 사실로 받아들인다고 하더라고 그것은 장기적으로 영향력을 발휘하는 구조적 요인에 기인하는 것이다. 그러므로 주어진 성장률 아래에서 일자리 창출력을 높이기 위한 노력도 장기적인 체질 강화에 역점을 두어야 한다.

The works of the special economic zone for regional development(SEZone) have been promoted for developing the regional economy corresponding with its own peculiarities by not national, but local level of government. Namely, those set the goal at specialized development of regions through an appeasement policy against regulations. So local governments. must originate the local works, get financial sources by itself, and then revitalize the regional economy. The policies of many local governments aim at increasing farmers' income by developing rural society to cope with open economy system. By the way they have tried to revitalize agriculture and rural society by promoting actively the works of SEZone through an appeasement policy against regulations. And it is important to search for specialized factors based on regional resources, and to make connected with them together so as to obtain good results in the works of SEZone. This study examined regulations related to environmentally friendly agriculture and green tourism. And it researched about the effect of SEZone works on regional economy and develops indices of result estimation. So schemes for strategies for increasing demand and development issues were presented.

Since 2019, Korea Ministry of Oceans and Fisheries has set the annual total allowable catch (TAC) by fish species, and has allocated the annual TAC into each fishery vessel. Also the Korea government plans to adopt the individual transferrable quota system in time. The TAC allocation is similar to the individual fishermen/fishing quota, which the US National Oceanic and Atmospheric Administration has implemented. However, the TAC based management faced fishermen's complaints and a debate is still underway about how to allocate TAC. Because the ideas of the Korea policy are from those in the foreign countries, I intended to provide the Korea fisheries community with an overview about how the TAC has been developed, what problem it caused, and foreign examples of how to allocate it. Furthermore, I pointed out a substantial room for improvement in their current practice of stock assessments, because, otherwise, their current methods for estimation of TAC by species cannot be trusted. Finally I made specific suggestions about what they need to do to reform their current stock assessments.

The study investigates the factors that affect Kyrgyzstan's bilateral trade flows with its main trading partners and attempts to predict trade potential for Kyrgyzstan. Using panel data, the gravity model is applied to estimate Kyrgyzstan's trade from 2000 to 2016 for its 35 main trading partners. The coefficients derived from the gravity-model estimation are then used to predict trade potential for Kyrgyzstan. Results proved to be successful and explained 63% of the fluctuations in Kyrgyzstan's trade. According to the results, Kyrgyzstan's and its partners' GDP have a positive effect on trade, while distance and partners' population prove to have a negative effect. Predicted trade potential reveals that neighboring countries (China, Kazakhstan, Uzbekistan, and Tajikistan) and Russia still have a significant trade potential. Kyrgyzstan, being a less developed economy, even by Central Asia standards, can only achieve its goals of reducing poverty and becoming more developed by increasing its overall trade with the rest of the world. Therefore, it is essential to study the main determinants of Kyrgyzstan's bilateral trade. In this way, we can help policy makers formulate policies to expand Kyrgyzstan's trade. This study is the first attempt to apply to the gravity model to Kyrgyzstan in an attempt to predict trade potential.

Purpose: Military maintenance involves corrective and preventive actions carried out to keep a system in or restore it to a predetermined condition. This research develops an optimal maintenance cycle for aviation oil testing equipment with acceptable reliability level and minimum maintenance cost. Methods: The optimal maintenance policy in this research aims to satisfy the desired reliability level at the lowest cost. We assume that the failure process of equipment follows the power law non-homogeneous Poisson process model and the maintenance system is a minimal repair policy. Estimation and other statistical procedures (trend test and goodness of fit test) are given for this model. Results: With time varying failure rate, we developed reliability-based maintenance cost optimization model. This model will reduce the ownership cost through adopting a proactive reliability focused maintenance system. Conclusion: Based on the analysis, it is recommended to increase the current maintenance cycle by three times which is 0.5 year to 1.5 years. Because of the system's built-in self-checking features, it is not expected to have any problems of preventative maintenance cycle.
