1992년 리우회의 이후 국제적으로 환경자원의 중요성이 인식되면서 환경자원에 대한 가치를 정량화하고자 하는 움직임이 본격화 되었다. 우리나라 역시 이러한 국제적인 추세에 영향을 받으면서 1990년초부터 비시장재화의 가치를 평가하고자 하는 연구가 본격적으로 시작되었다. 또한 1999년에 예비타당성조사가 도입되면서 대규모건설사업 수행 전에 환경자원의 가치까지 고려한 비용편익분석이 실제로 이루어지고 있다. 하지만 환경자원에 대한 가치평가 방법이 아직 정립되지 못한 실정이다. 본 연구에서는 환경자원의 가치 평가를 위한 이론과 주요 평가 방법을 소개하였다. 이론에서는 환경자원의 가치를 수요함수와 생산함수차원에서 검토하고 이들 두 함수가 함께 고려된 시장에서 최적 수준을 도출하였다. 평가 방법에서는 시장의 특성에 따라 대표되는 평가 방법인 여행비용법, 만족가격법, 가상가치평가법을 소개하였다.

선택형 공익직접지불제도는 농업인이 일정 수준 이상의 공익기능 증진 활동에 참여할 경우 경제적 유인을 제공하는 제도이다. 하지만 현행 선택형 공익직접지불제도는 과거의 직불제를 통합하는 수준에 그쳐 공익기능 증대에서 한계가 있다. 따라서 추진체계를 개편하여 농업의 공익기능에 대한 국민적 요구를 수용할 필요가 있다. 이에 본 연구는 계층화 분석적 의사결정법과 네트워크 분석적 의사결정법을 활용하여, 선택형 공익직접지불제도 추진체계의 우선순위를 설정하고 개편방안을 제시한다. 분석을 위하여 관련 전문가 51명을 대상으로 2020년 8월부터 약 두 달간 설문조사를 실시하였다. 분석결과 추진체계의 가장 중요한 목표는 효과성, 실행가능성, 농가수용성 중에서 효과성으로 분석되었다. 그리고 공익기능 증진을 위한 최적의 추진체계는 세부활동형, 묶음형, 포괄보조형 중 묶음형으로 분석되었다. 한편 묶음형의 경우 여러 세부활동 조합의 효과에 관한 연구가 부족하므로 농업환경보전 프로그램과 같은 기존의 사업을 활용하여 묶음형에 대한 시범사업을 진행할 필요가 있으며, 이에 대한 효과를 분석하여 체계적으로 정책을 수립할 필요가 있다. 본 연구는 선택형 공익직접지불제도 추진체계(안)의 평가를 통해 정책 추진 방향에 대한 지표를 제공함에 의의가 있다. 따라서 본 연구의 분석결과는 앞으로 공익직접지불제도 개편에 객관적인 근거로 활용될 것으로 기대된다.

Purpose: The use of flumazenil administration in the emergency department is still controversial because of concerns about adverse effects. The present study was conducted to re-evaluate the risk-benefit ratio associated with flumazenil administration to patients suspected of having acute hypnotics and sedatives poisoning in the emergency department. Methods: A retrospective chart review study was conducted for patients whose final diagnoses were "poisoning" and "benzodiazepine" or "sedatives-hypnotics" from Mar. 2006 to Feb. 2015. The basal characteristics of the patients, including past medical history, ingredients and dose of ingested drug and co-ingested drugs were investigated. For patients administered flumazenil, responsiveness and time from admission to flumazenil administration were investigated with supplement. All collected data were analyzed in aspect terms of risk/benefit. Results: A total of 678 patients were included in our study. Benzodiazepine was the most common sedative/hypnotic drug prescribed, and the frequency of prescription continuously increased. The proportion of TCA as co-ingestion decreased from 13.1% to 3.9% in patients with acute sedative/hypnotic poisoning. Flumazenil was administered to 55 patients (8.1%), of which 29 patients (52.7%) were applied to contraindications. Fifty-three patients (96.4%) showed positive responsiveness, including partial responsiveness after flumazenil administration. No severe adverse events were identified. Conclusion: Based on the current trends in prescription patterns for sedative/hypnotic drugs, increased use of non-TCA antidepressants, and responsiveness to administration of flumazenil, benefit seemed weighted more in this study, although the observed benefits were based on limited results. Further prospective multicenter studies will be needed to optimize benefit-risk ratio.

In an emergency management case, evaluating the economic value of information technology investments is a challenging problem due to the effects of decision making, uncertainty of disasters, and difficulty of measurements. Risk assessment and recovery process, one of the major functions in emergency management, consists of (1) measurement of damages or losses, (2) recovery planning, (3) reporting and approving budgets, (4) auctioning off recovery projects to constructors, and (5) construction for the recovery. Specifically and of our interest, measurement of damages or losses is often a costly and time-consuming process because the wide range of field surveys should be performed by a limited pool of trained agents. Managers, therefore, have to balance accuracy of the field survey against the total time to complete the survey. Using information technologies to support field survey and reporting has great potential to reduce errors and lowers the cost of the process. However, existing cost benefit analysis framework may be problematic to evaluate and justify the IT investment because the cost benefit analysis often include the long-run benefit of IT that is difficult to quantify and overlook the impact of managerial control upon the investment outcomes. Therefore, we present an alternative cost-centric control model that conservatively quantifies all cost savings to replace benefits in cost benefit analysis and incorporate the managerial control. The model provides a framework to examine how managerial decision making and uncertainty of disaster affect the economic value of IT investments. The current project in Emergency Agency in South Korea is introduced as a case to apply the cost-centric control model. Our work helps managers to better evaluate and justify IT-related investment alternatives in emergency management.

Background: Effective policy implementation is essential for a healthy workplace. The Ryan-Kossek 2008 model for work-life policy adoption suggests that supervisors as gatekeepers between employer and employee need to know how to support and communicate benefit regulations. This article describes a workplace intervention on a national employee benefit, Family and Medical Leave Act (FMLA), and evaluates the effectiveness of the intervention on supervisor knowledge, awareness, and experience with FMLA. Methods: The intervention consisted of computer-based training (CBT) and a survey measuring awareness and experience with FMLA. The training was administered to 793 county government supervisors in the state of Oregon, USA. Results: More than 35% of supervisors reported no previous training on FMLA and the training pre-test revealed a lack of knowledge regarding benefit coverage and employer responsibilities. The CBT achieved: (1) a significant learning effect and large effect size of d = 2.0, (2) a positive reaction to the training and its design, and (3) evidence of increased knowledge and awareness regarding FMLA. Conclusion: CBT is an effective strategy to increase supervisors' knowledge and awareness to support policy implementation. The lack of supervisor training and knowledge of an important but complex employee benefit exposes a serious impediment to effective policy implementation and may lead to negative outcomes for the organization and the employee, supporting the Ryan-Kossek model. The results further demonstrate that long-time employees need supplementary training on complex workplace policies such as FMLA.

The Ministry of Health and Welfare of Korea has implemented various social security programs to ensure a basic standard of living and raise overall quality of life for all citizens. The Korean social security system provides social insurance, public assistance, and social welfare services. To achieve adequate drug benefits, the Drug Management Department of Health Insurance Review and Assessment Service (HIRA) implement drug management duties including drug listing, upper price limit setting, scope of benefits, and post-factum management. When a manufacturer or an importer wants to apply for National Health Insurance (NHI) coverage of the drug that has obtained safety and efficacy approval, the pharmaceutical benefit assessment committee of HIRA evaluates the drug's clinical efficacy and cost-effectiveness to determine whether or not to include the drug into the benefit package. The benefit standards for a listed drug (ingredient) are set either for the whole permitted range or a part of range with conditions. To increase the coverage rate for new drugs, the listed drugs are regularly reviewed for their value. The status of listed drugs can be adjusted or eliminated from the benefit package if the clinical efficacy turns out to be insignificant. Therefore, through these pharmaceutical management procedures, high-quality drugs are provided at reasonable prices, which save healthcare expenditure by price determination and selective coverage in consideration of economic evaluation.

Background: The Environmental Health Action Program was a national project carried out from 2012~2021. It was aimed at developing public technologies to protect people's health from various environmental hazards. Objectives: One of the final goals of the project was "creating health benefits worth more than 179.2 billion won by reducing the environmental burden of disease." This study aims to evaluate whether the program sufficiently achieved the planned benefits. Methods: In order to secure consistency in evaluation, we applied the same equation used in the goal-setting process. It is comprised of six parameters to estimate the benefit: 1. The amount of medical expenses for environmental diseases; 2. The attributable proportion of environmental risk factors' 3. The rate of reduction in medical expenses for environmental diseases; 4. R&D project contribution; 5. The proportion of successful policy reflection; and 6. The contributions of the project. The corresponding variables were estimated at the end of the project, and the health benefits of the project were recalculated using the newly estimated variables. Results: It was estimated that a total of 195 billion won in health benefits occurred or will occur from 2015 to 2026. The main contributors for achieving the target were an increase in medical expenses for environmental diseases, a high score in the R&D project contribution, and the proportion of successful policy reflection. Conclusions: Technically, the equation used in the project is about medical expenses for environmental diseases rather than about the environmental burden of disease. There are several benefits of using the environmental burden of disease in the evaluation of public health policies. In further studies, developing a policy evaluation framework using indicators such as population attributable fraction would be needed.
