Wartime warship damage rate indicates how much damage of friend warships shall have occurred during naval battles accomplished under specific war operational plans. The wartime damage rate analysis provides the baseline of wartime resources requirements. If wartime damage rate is overestimated, the national finance will get to negative effects because of exceeding the budget for inventory, operation, and maintenance of resources. Otherwise, if wartime damage rate is underestimated, the national defense will lose in the war because of lack of critical resources. In this respect, it is important to estimate the wartime damage rate accurately and reasonably. This paper proposes a systematic procedure to estimate the wartime warship damage rate. The procedure consists of five steps; force analysis, operation plan analysis, input variable definition, simulation modeling, and output analysis. Since the combat simulation model is regarded as the main tool to estimate damage rate, the procedure is focused on the development of model and experiments using the model. A case study with virtual data is performed to demonstrate the effectiveness of the developed procedure.

국내 종합사업관리 용역비 산정을 위하여 대부분의 경우, 유사 사업관리 산정사례를 참고하여 추정하거나 과업참여자의 경험을 바탕으로 비용을 산정하였음을 알 수 있다. 이는 사업관리비 산정에 대한 정확성이 떨어져 사업을 주관하는 발주기관에서는 사업계획 및 예산 반영이 어려우며, 추정치에 의한 용역비 산정으로 향후 설계변경 등의 사업관리용역비 증가의 원인이 되기도 한다. 따라서 발주자와 용역 참여자가 보다 정확한 용역비를 산정하여 변경사항 등으로 인한 비용증가와 분쟁을 최소화하기 위해서는 용역비 산정기준을 객관적이고 과학적인 방법으로 적용할 필요가 있다. 종합건설사업 관리의 용역비 산정을 위해 기존의 경우에는 사례와 경험을 기초로 한 Top-Down 방식으로 접근하였다면, 본 연구에서는 사업관리 업무를 세부단계 및 활동(Activity)으로 분류하고 단계별로 WBS를 부여하여 각각 부여된 코드에 일정과 비용을 산정하는 Bottom-Up 방식의 사업관리 용역비를 산정하는 것으로, 용역비 산정을 위한 프로젝트 기준모델을 개발하고 프로젝트별 보정계수를 적용하여 용역비용을 산정하는 방식으로 이를 ICEP이라고 명명하였다. 또한 산정된 해당 과업의 비용과 추후 실적자료를 분석하여 보완함으로써 프로젝트별 특성을 반영한 종합사업관리 용역비 산정으로 효율적인 건설사업 관리가 가능해진다.

Together with housings, general buildings and industrial facilities, multi-purpose complexes are equipped with various and special equipment. They are often used by many unspecified people, which causes an increase in annual electricity consumption. Because of this, a great amount of money has been spent for electric charge, far more in excess of the budget, so a reasonable electricity rate needs to be estimated. In this study, we surveyed the power consumption, average power use, and annual electricity bill of multi-purpose complexes in the past five years. To see the general tendency of the survey, we conducted a statistical analysis with such parameters as average, maximum, and minimum values. Through regression analysis, we could see the trend of the survey in linear way. Based on the survey, we have developed an electric-rate calculation program to estimate the next year's budget on electricity.

Objectives : This paper analysed the alternative methods of calculating conversion factor for oriental medicine in the National Health Insurance and estimated the conversion factor(reimbursing price level) of the oriental medical services, based on health insurance claims data and macro economic data. Methods : Comparing cost accounting method, SGR model, and index model to estimate conversion factor in the national health insurance, six empirical models were derived depending on the scope of revenue considered in financial indicators. Classifications of data and sources used in the analysis were identified as officially released by the government. Results and Conclusion : Cost accounting analysis and SGR model showed a two digit decrease in the physician fee schedule of oriental medical services in the national health insurance, while index model indicated a positive increase in the fee reimbursed. As expected, SGR model measured an overall trend of health expenditures rather than an individual financial status of medical institutions, and index model properly estimated the level of payments to oriental medical doctors. Upon a declining share of health expenditures on oriental medicine, a global budget system fixed to a flat rate of total budget could be an opportunity as well as a challenge.

It is our goal to obtain a better scientific understanding of how to define the nature and role of remotely sensed land surface parameters and energy fluxes in the heat island phenomena, and local and regional weather and climate. By using the TRMM (Tropical Rainfall Measuring Mission) visible and thermal imagery data and analyzing the surface energy flux images associated with the change of the landcover and land use in the study area, we present how significant is the magnitude of the heat island heat effect and its relation with the surface parameters and the energy fluxes in the Taichung area of Taiwan. We used the energy budget components such as net radiation, soil heat flux, sensible heat flux, and latent heat flux in the study area of interest derived form remotely sensed data to understand the island heat effect in Taichung. The results show that water is the most important component to decrease the temperature, and the more the consumed net radiation to latent heat, the lower the urban surface temperature.

건설공사의 품질을 확보하고 예산의 절감을 도모하는 등 건설 프로젝트의 성공 여부를 판단하기 위해서는 객관적인 평가지표와 그에 대한 투명성 확보가 필요하다. 건설부문을 포함한 공공사업의 경우 대규모 예산투입이 이루어지고 있지만 그 결과물로 인한 편익을 산정하기 어려울 경우가 많아 공공사업의 효율성과 효용성이 떨어진다고 인식되고 있다. 따라서 본 연구에서는 500억 원 이상의 공공공사 중 사후평가를 실시하는 시설물에 대한 소비자 만족도를 정량화하는 것을 범위로 하여, 공공공사 사후평가 시 체계적이고 정량적인 측정이 가능할 수 있도록 주민 호응도와 사용자 만족도 항목을 중심으로 하는 사후평가 측정기준을 제안하고자 한다.

This study was conducted to estimate the distribution characteristics and budget of organic matter in the Lake Hapcheon. In the dry season, the concentration ranges of organic carbons were similar, but in the rainfall season, it showed about double concentrations. Changes of vertical water quality in the lake, there were no big differences with the concentration by the depth. However, it tends to be relatively high on the surface, a little low on the mid-depth and high in the lake bottom. DOC rate at TOC, it was lower than POC rate at inflow and DOC rate was higher than POC rate in the lake and discharging water. R-DOC accounted for more 80% of DOC rate in all investigated areas, therefore we judge that this R-DOC is to increase the organic carbon pollution gradually. As the result of the calculated organic carbon budget in the Lake Hapcheon, the amount of allochthonous, autochthonous and release were 3,552, 3,288, 228 tonC/year, respectively. the amount of discharge, decomposition and sedimentation were 504, 1,344, 5,520 tonC/year, respectively. According to this investigation, the changed amount of organic matter in the Lake Hapcheon recorded -300 tonC/year with the increase of 7,068 tonC/year and the decrease of 7,368 tonC/year.

The purpose of this study is to elicit preference for drug listing decision criteria and to estimate the ICER threshold in South Korea using the discrete choice experiment (DCE) method. To collect the data, a DCE survey was administered to a subject sample either educated in the principle concepts of pharmacoeconomics or were decision makers within that field. Subjects chose between alternative drug profiles differing in four attributes: ICER, uncertainty, budget impact and severity of disease. The orthogonal and balanced designs were determined through computer algorithm to take the optimal set of drug profiles. The survey employed 15 hypothetical choice sets. A random effect probit model was used to analyze the relative importance of attributes and the probabilities of a recommendation response. Parameter estimates from the models indicated that three attributes (ICER, Impact, Severity of disease) influenced respondents' choice significantly(p${\pm}$0.001). In addition, each parameter displayed an expected sign. The Lower the ICER, the higher the probability of choosing that alternative. Respondents also preferred low levels of uncertainty and smaller impact on health service budget. They were also more likely to choose drugs for serious diseases rather than mild or moderate ones. Uncertainty however is not statistically significant. The ICER threshold, at which the probability of a recommendation was 0.5, was 29,000,000 KW/QALY in expert group and 46,500,000 KW/QALY in industry group. We also found that those in our sample were willing to accept high ICER to get medication for severe diseases. This study demonstrates that the cost-effectiveness, budget impact and severity of disease are the main reimbursement decision criteria in South Korea, and that DCE can be a useful tool in analyzing the decision making process where a variety of factors are considered and prioritized.
