본 연구에서는 단일 환산지수 체계를 유형별 외래 및 입원 환산지수로 분리하기 위한 이론 모형을 설계하였다. 그리고 가상 자료를 바탕으로 외래 및 입원 환산지수와 조정계수를 산출하였다. 본 연구에서의 중요한 결론은 다음과 같다. 첫째, 외래·입원 환산지수 개념을 도입하고 설계함으로써 의원은 외래, 병원은 중한 환자 위주의 입원 기능에 집중하도록 유도할 수 있는 최소한의 인센티브 도구를 도입할 수 있다. 둘째, 환산지수를 분리함으로써 상급종합병원을 비롯한 대형병원의 외래 진료비 수입이 목표 진료비 예산 이상으로 증가하더라도 병원수익 증대에 큰 도움이 되지 않도록 보상 체계를 설계할 수 있는 방안을 도입해 자원 배분 동기를 부여할 수 있다. 셋째, 단일 환산지수보다 다양한 요소들에 대한 명시적인 계약이 가능해져 급증하는 진료비에 대한 적절한 관리 수단으로 활용할 수 있다. 마지막으로 외래 및 입원 환산지수 분리 계약은 공급자의 행위론적인 변화를 유도해 의료전달체계를 정립하는데 기여할 수 있는 정책적인 도구로 활용될 수 있을 것이다.

본 연구는 의료기관평가점수의 유용성을 높이기 위한 목적으로 수행되어 2004년부터 2008년까지 공시된 의료기관평가점수를 바탕으로 효율성지표를 이용해 환산지수를 추정하는 모형을 구축하였다. 의료기관평가영역별로 부여된 다양한 평가항목점수를 AHP를 통해 축약하고 이를 DEA_AR모형에 사용함으로써 추가적인 정보를 제공하는 유용한 예측모형을 구성할 수 있었다. 의료기관평가점수와 신임병원자료, 건강보험공단 자료를 연결해 분석 가능한 자료를 생성하고 DEA, 요인분석, 일반 선형모형을 이용해 환산지수, 효율성, 환산지수와 효율성을 결합하는 모형을 제시하였다. 개별 병원의 투입물과 산출물 뿐 만 아니라 의료기관평가점수, 종별구분, 지역별 분포 등이 환산지수의 영향변수로 파악되었다. 따라서 본 연구에서 제시된 AHP와 DEA_AR을 기반으로 한 효율성지표를 사용해 환산지수를 구하고 이를 수가계약에 활용함으로써 보건의료에 기여할 것으로 판단된다.

This study explores a structural model to examine the relationship between web browsing motivation, retail strategy and purchase conversion for apparel on shopping websites. A self-administered questionnaire based on existing scales includes web browsing motivation, retail strategy, and purchase conversion intention of apparel on the shopping websites. A total of 499 usable questionnaires were obtained from consumers aging 20 to 49 who reside in metropolitan cities in Korea. For data analysis, descriptive statistics, exploratory factor analysis, confirmatory factor analysis, and structural equation models were used via SPSS 12.0 and LISREL 8.8. Findings concluded that web browsing motivations consisted of three factors: hedonic, informational, and recreational browsing for apparel. Hedonic browsing had a negative effect on purchase conversion intention, whereas informational browsing had a positive effect on the purchase conversion intention for apparel on shopping sites. Retail strategies on the website were classified into service, merchandise assortment, and price & promotion; the three elements of retail strategies mediated the relationship between web browsing motivations and purchase conversion intention for apparel. Specially, merchandise assortment had significantly direct effect on the purchase conversion intention of apparel on shopping websites. Managerial implications were discussed for fashion marketers to develop retail strategies and web content in order to convert web browsers or visitors into purchasers.

Contract power conversion factor which is applied to estimate contract power of industrial customers is an important standard to calculate transformer capacity. This paper shows a reasonable contract power conversion factor, that was made by the systematic and statistical way considering actual conditions, such as investigated contract power and peak power for the last 5 years of each customer for industrial customers as to AMR system. In this dissertation, it is necessary to analyze the key features and general trend from the investigated data. It made an analysis of the feature parameters, such as average, standard deviation, median, maximum. minimum and thus it was carried the linear and nonlinear regression analysis. Therefore, this paper compared characteristics for a contract power conversion factor which is applied to calculate contract power with characteristics for a regression model for customers which maximum utilization factor of transformer is more than 60%.

Contract power conversion factor which is applied to estimate contract power of general customers IS an important standard to caculate transformer capacity. This paper shows a reasonable contract power conversion factor, that was made by the systematic and statistical way considering actual conditions, such as investigated contract power and peak power for the last 5 years of each customer for 132 office building customers as to AMR system. In this dissertation, it is necessary to analyze the key features and general trend from the investigated data. It made an analysis of the feature parameters, such as average, standard deviation, median, maximum, minimun and thus it was carried the linear and nonlinear regression analysis. Therefore, this paper compared characteristics for a contract power conversion factor which is applied to calculate contract power with characteristics for a regression model for customers which maximum utilization factor of transformer is more than 60%.

Soil volume conversion factors are used for estimation of an excavated the soil volume which will be removed or added in levelling the ground surface of a construction site. An accurate evaluation method will help us reduce a construction cost and time consuming. In this study, we performed the laboratory tests, including grain size measurement, water content, specific gravity, porosity, density and XRD tests, to suggest reliable soil volume conversion factors and weathering indices in field using nondestructive methods. The weathering index and soil volume conversion factor L are obtained for different types of soils. At results, the CIW index is the best method measuring the weathering index and the factor L is relative to natural porosity, void ratio, density and dry density.

건설교통부에서는 예산절감을 위해 토석정보시스템을 운영하고 있으며, 시스템 운영에 기본적으로 고려되어야 할 사항은 원지반의 토량을 기준으로 산정되는 토량 변화율인 토량환산계수의 정확한 적용이다. 토공사의 절성토량의 균형, 사토장 및 토취장의 계획은 공사비와 직접적인 관계를 가지고 있기 때문에 정확한 토공량 산정 및 효율적인 토공유동이 무엇보다도 중요하다고 할 수 있다. 그러나 현장에서의 비합리적인 토량환산계수의 적용으로 토공유동이 효과적이지 못한 점이 있으며, 정확한 공사비 산정 및 투입에도 지장을 초래할 수 있다. 이와 같이 효율적인 토공유동계획은 토공량 산정의 정확도에 기인한다고 할 수 있으며, 정확한 토량환산계수의 적용이 토공량 산정에 절대적이라 할 수 있다. 본 연구에서는 대규모 토공사가 실시되는 현장을 대상으로 대상지 내의 임의지점 절 성토부를 굴착하고 굴착 전후 및 다짐후의 체적을 사진측량기법 및 레이저스캐닝기법으로 정밀한 수치표고모형을 제작하여 토량환산계수를 산정하고, 동시에 절 성토부 건조밀도시험을 통해 산정되는 토량변화율의 결과값과 비교 분석하여 신뢰성 있는 토량환산계수의 산정방법을 결정하고자 한다.

Objectives: To introduce to TKM scientific dose conversion methods of human to animal or animal to human for new drug investigations. Methods: We searched guidelines of the FDA and KFDA, and compared them with references for drug-dose conversion from various databases such as PubMed and Google. Then, we analyzed the potential issues and problems related to dose conversion in safety documentation of new herbal drugs based on our experiences during Investigational New Drug (IND) applications of TKM. Results: Dose conversion from human to animal or animal to human must be appropriately translated during new drug development. From time to time, investigators have some difficulty in determining the appropriate dose, because of misunderstandings of dose conversion, especially when they estimate starting dose in clinical or animal studies to investigate efficacy, toxicology and mechanisms. Therefore, education of appropriate dose calculation is crucial for investigators. The animal dose should not be extrapolated to humans by a simple conversion method based only on body weight, because many studies suggest the normalization method is based mainly on body surface area (BSA). In general, the body surface area seems to have good correlation among species with several parameters including oxygen utilization, caloric expenditure, basal metabolism, blood volume and circulating plasma protein. Likewise, a safety factor should be taken into consideration when deciding high dose in animal toxicology study. Conclusion: Herein, we explain the significance of dose conversion based on body surface area and starting dose estimation for clinical trials with safety factor.

Purpose: This paper analyzed alternative methods of calculating the conversion factor for nurse-midwife's delivery services in the national health insurance and estimated the optimal reimbursement level for the services. Methods: A cost accounting model and Sustainable Growth Rate (SGR) model were developed to estimate the conversion factor of Resource-Based Relative Value Scale (RBRVS) for nurse-midwife's services, depending on the scope of revenue considered in financial analysis. The data and sources from the government and the financial statements from nurse-midwife clinics were used in analysis. Results: The cost accounting model and SGR model showed a 17.6-37.9% increase and 19.0-23.6% increase, respectively, in nurse-midwife fee for delivery services in the national health insurance. The SGR model measured an overall trend of medical expenditures rather than an individual financial status of nurse-midwife clinics, and the cost analysis properly estimated the level of reimbursement for nurse-midwife's services. Conclusion: Normal vaginal delivery in nurse-midwife clinics is considered cost-effective in terms of insurance financing. Upon a declining share of health expenditures on midwife clinics, designing a reimbursement strategy for midwife's services could be an opportunity as well as a challenge when it comes to efficient resource allocation.
