  • 건물의 노후화로 인한 리모델링의 활성화에도 불구하고 지금까지는 공동주택의 리모델링에 대한 연구가 주로 이루어졌고, 일반 업무용 건축물을 대상으로 한 연구는 미비한 실정이다. 이는 일반 업무용 건축물의 경우 건축주나 사용자의 입장에서 투자에 따른 수익이 보장되거나, 건축물 자산가치의 향상이 기대되는 경우에 한해서 리모델링이 진행되어 정확한 통계와 권리분석이 어려운 문제점을 지니고 있다. 또한 영세한 건축주의 입장에서는 리모델링에 필요한 자금 확보와 리모델링에 따른 수익성에 대한 면밀한 검토 작업이 어려워 소규모 업무용 건축물은 리모델링이 어려운 실정이다. 이에 상업용 건축물의 리모델링을 위한 경제성과 가치를 파악할 수 있는 기준이 마련하기 위하여 기존의 건축물의 가치평가를 위한 기준을 AHP기법 등을 이용하여 평가하고 이에 대한 타당성 분석 등을 통해 리모델링의 가치평가를 위한 기준을 마련하였다.

  • 철도관련 사업 및 연구개발시 수행하는 타당성조사에서 환경적 파급효과 산정의 중요성이 증대되고 있다. 그러나 현재의 투자평가시 고려되는 평가항목은 이동성에 기반한 효율성 위주의 항목으로 구성되어 있다. 현재 시행되는 예비타당성조사 및 타당성 평가의 주요 계량화 항목을 보면 차량운행 비용절감 편익, 통행시간 절감편익, 교통사고 감소편익, 환경비용 절감편익으로 분류된다. 현재의 환경비용 절감편익은 단순히 오염물질별 원단위에 따른 산정에 그치고 있어 최근 녹색성장 및 지속가능한 교통체계의 패러다임에 맞는 사회경제적 평가항목의 도입이 필요하다. 국내의 타당성 평가내용을 보면 계량화가 힘든 부분은 정책적 분석에서 고려되나 참고사항에 그치고 있어 계량화가 가능한 방법론의 개발이 필요하다. 대표적인 환경편익인 소음, 공간영향과 대기오염에 관한 평가체계의 정립이 필요한 시점이다. 따라서 본 연구는 기존 국내외 환경비용 절감편익 연구의 내용분석을 바탕으로 능동조향대차 연구의 타당성 분석을 사례로 적절한 평가항목에 관한 연구방향을 제시하고자 한다.

  • 본 연구의 목적은 Fisher(1995, 2003)의 다차원적 정책평가방법 중 상황적 타당성 평가를 활용하여 우리나라의 장애인 고용·일자리 정책을 평가하고 그에 따른 정책적 함의를 도출하는 것이다. 우리나라에서 진행된 다수의 장애인 고용·일자리 정책평가 연구들이 계량적인 연구방법에 치우쳐 균형 있고 종합적인 평가에는 소홀한 측면이 있었다. 본 연구에서는 기존의 실증주의적 방법론의 한계를 보완하는 질적 또는 현상학적 접근을 통해 균형 있는 정책평가를 시도하였다. 연구결과, 장애인 고용서비스·일자리의 개선을 위해 기관 간 연계·협력 강화, 고용서비스 사각지대 해소, 질적 개선, 맞춤형 고용서비스 확대, 프로그램 내실화, 정책·제도적 환경개선, 개인 심리정서적 지원강화가 향후 우리나라 장애인고용정책에서 중요한 것으로 나타났다.

  • Purpose: The purpose of this study was to evaluate the psychometric quality and feasibility of measurements for screening dysphagia in older adults to identify the 'right tool' for nurses to use in nursing homes. Methods: A systematic review was done. Electronic databases were searched for studies related to dysphagia screening measurements. A checklist was used to evaluate the psychometric quality and applicability. Tools were evaluated for feasible incorporation into routine care by nurses. Results: 29 tools from 31 studies were identified. Dysphagia screening tools with an acceptable validity and reliability had sensitivity between 68% and 100% and specificity between 52% and 100%. The Gugging Swallowing Screen (GUSS) and the Standardized Swallowing Assessment (SSA) were the tools with high psychometric quality, especially with high sensitivity, that nurses could perform feasibly to identify the risk and to grade the severity of dysphagia and aspiration of nursing home residents. Conclusion: Results show that GUSS and SSA are reliable and sensitive tools for screening dysphagia which nurses can use in nursing homes. Further research is needed to examine feasibility of screening with identified tools, and also, to establish effective and standardized protocols for these tools so they can be effectively incorporated into routine care.

  • The objective of this work is not only to perform feasibility studies on the CFD (computational fluid dynamics) analysis for the capillary system design but also to provide an enhanced understanding of the autonomous capillary flow. The capillary flow is evaluated by means of the commercial CFD software of FLUENT, which includes the VOF (volume-of-fluid) model for multiphase flow analysis. The effect of wall adhesion at fluid interfaces in contact with rigid boundaries is considered in terms of static contact angle. Feasibility studies are first performed, including mesh-resolution influence on pressure profile, which has a sudden increase at the liquid/gas interface. Then we perform both 2D and 3D simulations and examine the transient nature of the capillary flow. Analytical solutions are also derived for simple cases and compared with numerical results. Through this work, essential information on the capillary system design is brought out. Our efforts and initial success in numerical description of the microfluidic capillary flows enhance the fundamental understanding of the autonomous capillary flow and will eventually pave the road for full-scale, computer-aided design of microfluidic networks.

  • Recently, risk analysis studies regarding the architecture development project have been carried out by applying probabilistic method. However, it had a limit that this studies was conducted in only an apartment. Therefore, the objective of this study is to develop an optimal price estimation model that can be utilized on residential officetel project by applying Monte Carlo simulation. To achieve the objective, first, the variables are selected affecting the feasibility of an officetel based on literature review. Second, causal loop diagram is constructed by arranging the relationship between variables, then the import and expense model is suggested. Third, to carry out optimized parcel price, the range limits are set for each variables then Monte Carlo simulation is performed. In the future, the developed model is expected to help decision-makers as a tool to determine both risk and feasibility of the officetel development project.

  • It has been talked about the responsibility of the South-North Korean e-market place(e-MP) collaboration project every you since 2003. However, the feasibility as the business has not been dealt with in detail due to the uncertain environment as well as the complicated procedures of the project. The research focuses on the workable mechanism of the South-North Korean E-Market Place collaboration project. The feasibility of the project results from the newly installed fiber telecommunication network as well as the 1 billion dollars of the trading volume between South and North Korea. The research analyzes on the capabilities as well as willingness of the South and North Korea for the e-MP, and concludes with two paradigms of the future tasks. First, the unified but step-wise structure should be made to promote the project by the political committee (South and North Korea EC Committee) and the economical administration body (South and North Korea EC Corporation). Second, the market-oriented resolution system such as South and North Korea Arbitration Body should be involved to create legal environment. Above all, the discussion should be on the main body of e-MP settlement to abolish the psychological as well as practical barriers to enter the South-North Korean electronic commerce.

  • The structural feasibility of a variety of non-conventional sludge digesters, in the form of thin shells of revolution constructed in concrete, has formed the subject of investigation of a recent programme of research at the University of Cape Town. Such forms are usually known in the literature as "egg-shaped", and the advantages of these over conventional digesters of the wide-cylindrical type are now well-recognised: superior mixing efficiency, less accumulation of deposits at the bottom, easier removal of bottom deposits and surface crust, reduced heat losses, and so forth. With the aim of exploring the structural feasibility of various non-conventional forms for concrete sludge digesters, and making available usable analytical data and practical guidelines for the design of such thin shell structures, a number of theoretical studies have recently been undertaken, and these have covered conical assemblies, spherical assemblies and parabolic ogival configurations. The purpose of the present paper is to bring together the different analytical approaches employed in each of these studies, summarise the main findings in each case, draw comparisons among the various studied configurations with regard to structural efficiency and functional suitability, and make appropriate conclusions and recommendations.

  • Land cover (LC) is an important factor in socioeconomic and environmental studies. According to various studies, a number of LC maps, including global land cover (GLC) datasets, are made using polar orbit satellite data. Due to the insufficiencies of reference datasets in Northeast Asia, several LC maps display discrepancies in that region. In this paper, we performed a feasibility assessment of LC mapping using Geostationary Ocean Color Imager (GOCI) data over Northeast Asia. To produce the LC map, the GOCI normalized difference vegetation index (NDVI) was used as an input dataset and a level-2 LC map of South Korea was used as a reference dataset to evaluate the LC map. In this paper, 7 LC types(urban, croplands, forest, grasslands, wetlands, barren, and water) were defined to reflect Northeast Asian LC. The LC map was produced via principal component analysis (PCA) with K-means clustering, and a sensitivity analysis was performed. The overall accuracy was calculated to be 77.94%. Furthermore, to assess the accuracy of the LC map not only in South Korea but also in Northeast Asia, 6 GLC datasets (IGBP, UMD, GLC2000, GlobCover2009, MCD12Q1, GlobeLand30) were used as comparison datasets. The accuracy scores for the 6 GLC datasets were calculated to be 59.41%, 56.82%, 60.97%, 51.71%, 70.24%, and 72.80%, respectively. Therefore, the first attempt to produce the LC map using geostationary satellite data is considered to be acceptable.
