  • The social and economical value assessment of railway facilities implies unaccountable values such as: reduction of travel time, reduction of car accident, reduction of air pollution. However, the value of railway facilities has been evaluated as the transportation and management results. The investment and management results of railway need to be considered objectively. Therefore, this study established the economical value assessment method of railway facilities composed of 10 items of economical value through the existing a preliminary assessment investigation, a manual of railway investment assessment, paper study. In addition, this study proposed the strategy for the value assessment of railway facilities before and after.

  • The use of nanotechnology materials and applications in the construction industry should be considered for enhancing material properties. However, in this paper, the technical and economical assessment of applying silica nanoparticles for construction of concrete structure is studied. In order to obtain the equivalent material properties of the structure, the Mori-Tanaka model is used considering agglomeration of nanoparticles. The effect of using these nanoparticles on mechanical properties of concrete, such as the modulus of elasticity, compressive strength, as well as its indirect effect on armature percentage is investigated. Finally, the price of silica nanoparticles and its effect on the price increase of concrete structure is investigated. The results show that increasing the volume percent of silica nanoparticles up to 10% improves elastic modulus 111% and reduces amateur percentage up to 72%.

  • This research is aiming to specify the requirement of the investment such as intial cost, running cost earning rate to make effective investment considering the purpose of remodeling and economical value of store building enough to meet the initial purpose of remodeling. The review of earning for economical evaluation was performed by the on-site auditing on the structure and function of the building and applying the assessment simulation program, which is to find the possible business model to identify the requirement of building owner through case study. After the research, the following results are obtained. First, it is important that many aspects should be carefully analysis and the best method should be selected as characteristics of remodeling can be defer each other in their implementations. Second, though the remodeling of exist building to promote the functions has been applied, no suitable assessment tool has bee developed for deciding the level of remodeling in the view of economical efficiency so far. Third, the economical benefit was evaluated by analysing annual earning rate which is applied by investment items and recovery period for the investment. More specific date base should be established to apply the suggested economic acessments in business enough ti forecast the future circumstances. More researches should be promoted on the area continuously as well as the integrated economic evaluation of remodeling on existing building.

  • Objectives: The aim of this study is reviewing the literature to extract the key parameter, study design, perspective, cost-effectiveness index and find the calibration parameter for the clinical study with economical evaluation protocol on facial palsy. Methods: Literature search is performed using PUBMED for literature published from January 2000 to December 2016. We included randomized controlled trials(RCTs) and modelling study with economic assessment in which human participated. Results: As a result of literature search, the 198 articles were found. After reviewing the title, abstract and full text, the 5 articles were selected. Selected articles are classified into 4 RCT studies dealing with quality of life and 1 CEA(cost-effectiveness analysis) study. Conclusions: We found reliable key parameters, calibration parameters and elements of economical assessment study, which might be necessary factors for developing research protocol of clinical trial with economic evaluation about facial palsy patients.

  • Objectives : The aim of this study is reviewing the literature to extracting the key parameter and finding the calibration parameter for the clinical study with economical assessment protocol on atopic dermatitis. Methods : Literature search is performed using PUBMED for literature published from Janurary 2000 to December 2016. We included randomized controlled trials(RCTs) with economic assessment in which human participants. Results : Among the articles published from January 2000 to December 2016, The 1464 articles were found. After reviewing the title, abstract and full text, the five articles were selected. Selected articles are classified 3 CEA(cost effective analysis)study, 1 CMA(cost minimizing analysis)study and 1 cost analysis study. Conclusions : We found highly reliable key parameters and calibration parameters, which might be necessary factors for developing research protocol of economic evaluation alongside clinical trial about atopic dermatitis patients.

  • This study aims to propose an assessment model on environmental economics which will provide useful information in making a decision for the implementation of pro-environmental and economical construction projects. To meet the objective, this study suggests a procedure to estimate environmental cost of construction projects. The model combines environmental load assessment and environmental value assessment. The environmental cost of pollutant generated from the construction project was estimated utilizing the Contingent Valuation Method (CVM) which is a value assessment method borrowed from economic science. The devised model is expected to provide a useful methodology that will scientifically support the planning and management of sustainable construction not only in the environmental aspect but also in the economical aspect.

  • 본 연구는 바이오가스화 처리 유 무에 따라 하수슬러지 처리방법별, 즉 소각, 탄화, 건조, 고형화 등에 대한 환경성 및 경제성 분석을 실시하였다. 추가적으로 혐기 소화효율 45 %, 함수율 95% 등 정부정책 가이드 라인에 때한 경제적 타당성 조사도 실시하여 정책수립의 과학적 근거자료로 제시하고자 하였다. 경제성 분석을 위하여 30개의 혐기소화 소유 시설과 17개 소유하지 않는 시설을 조사하였다. 결과적으로, 환경성 및 경제성을 고려할 때 혐기소화 이후 후처리로 소각 또는 건조하는 경우가 가장 타당한 것으로 분석되었으며, 후처리로 탄화처리하는 경우가 가장 타당성이 적은 것으로 분석되었다. 고형화 처리는 가장 경제적이었으나 환경적 및 운전성이 부족하여 타당성이 부족한 것으로 분석되었다.
