The Activity Based Costing(ABC) means the process that makes clear how the actions and input resources have changed into service to calculate medical services costs. These days, the number of hospital which is using the ABC system is increasing to make their policy decision making efficient and run the hospitals more resonable. This study analyzes the unbalance in the level of health insurance service fee and the improvement plans based from 8 hospitals(ABC system) and 95 clinics(ABC survey). The cost recovery ratio has shown different levels according to each service type. A surgery service type recorded 76.8% and an evaluation & management service type is 84.6%, a treatment procedure type(85.8%), a function test type(91.6%) and health insurance fee even did not reach to the original cost. Meanwhile, a laboratory test type and imaging test type show high level of cost recovery ratio. they recorded 188.3% and 158.8%. Resultingly now of unbalance in the level of health insurance service fee accelerates supply of every test. so there is a need to make laboratory test type and imaging test type lower to keep balance with the surgery and medical service. These methods should be performed gradually with monitoring the unbalance fee ratio and for this, a panel medical institution have to be established for generalizations of studying result, fairness of selecting researching sample.

Today, there is a growing need of environment-friendly buildings, so-called 'green', facilities, and energy saving buildings to decrease environmental pollutants released into cities by construction activities. Green-Building Information Modeling (Green-BIM) is a purpose-built solution which supports to forecast energy consumption of 3-D model of a building by augmenting its primary 3-D measurements (width, height and depth) with many more dimensions (e.g. time, costs, social impacts and environmental consequences) throughout a series of sequential phases in the lifecycle of a building. The current study was carried out in order to integrate vegetation systems (particularly green roof and green wall systems) and investigate thermal performance of the new Sainsbury's building which will be built on Melton road, Leicester, United Kingdom. Within this scope, a 3-D building model of the news Sainsbury's building was first developed in $Autodesk^{(R)}$ $Revit^{(R)}$ and this model was then simulated in $Autodesk^{(R)}$ $Ecotect^{(R)}$once weather data of the construction site was obtained from $Autodesk^{(R)}$ Green Building $Studio^{(R)}$. This study primarily analyzed data from (1) solar radiation, (2) heat gains and losses, and (3) heating and cooling loads simulation to evaluate thermal performance of the building integrated with vegetation system or conventionally available envelops. The results showed that building integrated vegetation system can potentially reduce internal solar gains on the building rooftops by creating a 'bioshade'. Heat gains and losses through roofs and walls were markedly diminished by offering greater insulation on the building. Annual energy loads for heating and cooling were significantly reduced by vegetation more significantly through the green roof system in comparison to green wall system.

Objectives : The purpose is to introduce the recent large-scale clinical researches for safety, efficacy and effectiveness of acupuncture in Germany. Results : In 2000, the German Federal Committee of Physicians and Health insurer proposed that large research initiatives on acupuncture, Acupuncture Model Projects(Modellvorhaben Akupunktur), could be conducted by health insurance companies for several pain that acupuncture is syndromes to justify the insurance-based reimbursement. Accordingly, 4 clinical researches were carried out; the Acupuncture Safety and Health economics studies(ASH), the Acupuncture Randomised Trial(ART), the Acupuncture in Routine Care studies(ARC), and the German Acupuncture trial(GERAC). Meanwhile, ASH is a prospective observational study for safety and costs. ART and GERAC are composed of RCTs for efficacy. ARC includes 6 pragmatic RCTs with additional non-randomized cohort study for effectiveness. We investigated the papers related to them and discussed about the outcomes. The researches showed that acupuncture is effective in practice for several chronic conditions such as migraine, tension-type headache, chronic low back pain, osteoarthritis of knee, dysmenorrhea, and allergic rhinitis. Based in part on them, the German health authorities decided that acupuncture would be included into routine reimbursement by social health insurance funds for chronic low back pain and chronic osteoarthritis of the knee in 2006. Conclusions : The German clinical researches may suggest the clues for establishing the evidence of acupuncture treatment.

Although the NutriPlus program has shown considerable evidence of enhancing users' nutritional status, the budget does not cover all eligible mothers and children. This study aimed to conduct a cost-benefit analysis of the NutriPlus program to assess its economic efficiency. 53 families with 79 users in the NutriPlus program at Daejeon Dong-gu Health Center participated in this study with informed consent. The costs and benefits were estimated from both the administrator's and users' perspectives. We converted the time cost into Korean currency based on the minimum wage in 2014. The value of nutrition education and service (B2), estimated by contingency valuation method (CVM), was counted as an economic benefit. 6 families (11.3%) were recipients of national medical care and 22 families (41.5%) paid 10% of the food package cost by themselves. The total cost was \7,450,167 and the total benefit was \12,402,239. The budget for the health center (C1+C2+C3+C4) was \5,984,381 a month. Time and transportation cost for receiving nutrition education (C6) differed significantly according to the economic status of families. Household food consumption increase (C4-B4) was 40,379 in the poverty group, which was four times more than in the other groups. The net benefit (B-C) was \4,852,172 and the B/C ratio was 1.66. Therefore, the NutriPlus program is beneficial in the economic aspect as well as in the nutritional aspect. If the enhancement of nutritional status was also considered, the total benefit would be even higher. These results confirm the legitimacy of a secure budget for the NutriPlus program. And we suggest expanding its budget to cover more eligible individuals to improve people's health and welfare.

개발부담금 제도는 1989년 개발이익을 환수하기 위해 도입되었으나 현재까지 20여차례 개정되는 등 많은 변화를 겪었다. 이처럼 빈번한 개정이 이루어진 주요한 이유는 개발부담금 부과를 위한 개발비용에 대한 정의 및 산정이 복잡하고 불분명하여 관련 주체 간 갈등이 발생하였기 때문으로 이를 최소화할 수 있는 개발비용 산정방식의 간소화가 시급히 필요하다. 본 연구는 최근 "개발이익환수에 관한 법률" 개정에 따라 일정면적 이하 사업에 대해 단위면적당 표준비용을 적용함에 있어 합리적이고 객관적인 적용방안 도출을 위해 다양한 지역별 사업유형별 적용방안의 차이를 통계적으로 검증하고 정책적 시사점을 제시하였다. 분석자료로는 최근 3개년간 전국 시군구에서 부과한 개발부담금 및 개발비용 관련 전수조사 자료 9,362건을 활용하였다. 분석결과 수도권/비수도권별로 구분하는 방식이 유의미한 차이를 발생하였고 집단 간 구분도 명확하게 나타났다. 본 연구결과는 개발부담금 제도를 합리적으로 개편하여 사회갈등을 최소화시키면서도 토지공개념 실현에 기여할 것으로 예상된다.

Backgrounds: Inpatient Classification System for Korean Medicine (KDRG-KM) was developed and has been applied for monitoring the costs of KM hospitals. Yet severity of patients' condition is not applied in the KDRG-KM. Objectives: This study aimed to develop the severity classification methods for KDRG-KM and assessed the explanation powers of severity adjusted KDRG-KM. Methods: Clinical experts panel was organized based on the recommendations from 12 clinical societies of Korean Medicine. Two expert panel workshops were held to develop the severity classification options, and the Delphi survey was performed to measure CCL(Complexity and Comorbidity Level) scores. Explanation powers were calculated using the inpatient EDI claim data issued by hospitals and clinics in 2012. Results: Two options for severity classification were deduced based on the severity classification principle in the domestic and foreign DRG systems. The option one is to classify severity groups using CCL and PCCL(Patient Clinical Complexity Level) scores, and the option two is to form a severity group with patients who belonged principal diagnosis-secondary diagnosis combinations which prolonged length of stay. All two options enhanced explanation powers less than 1%. For third option, patients who received certain treatments for severe conditions were grouped into severity group. The treatment expense of the severity group was significantly higher than that of other patients groups. Conclusions: Applying the severity classifications using principal diagnosis and secondary diagnoses can advance the KDRG-KM for genuine KM hospitalization. More practically, including patients with procedures for severe conditions in a severity group needs to be considered.

It was well received that well grounded behavioral theories were important in the development of effective nutrition education programs, but there are only a few programs available for Korean women. The objective of this study was to develop nutrition education programs for childbearing-aged women in Korea. Based on the findings of the needs assessment for the program and theoretical backgrounds, we developed behaviorally oriented tailored nutrition education program including motivation (MT), modifying (MD) and maintenance (MA) stages. The key concepts of the stages were motivation promotion for MT, increasing behavioral capabilities for MD, and strengthening self-management and building favorable environmental condition for MA. The education program was intended to be need in individual nutrition counseling, but it could be well used for group education by developing materials using the relevant contents. The primary users of the program were nutrition educators, however it could be also used by clients as needed. The introductory chapter provided dietary assessment tools and nutrition education tips. MT chapter included subjects such as nutritional status screening, costs of inappropriate nutrition and weight management, benefits of eating right, and activities for motivation promotion. MD stage chapter dealt with topics of healthy weight, knowledges and skills for better eating habits and physical activity status, and activities related to setting tailored behavioral objectives. MA stage focused on facilitating self management skills and building helping relationships. Each stage underlined activities using various educational tools in order to promote active participation of the client (s). For better use of this program, it was recommended to conduct program validation study.
