  • 오늘날 고령인구의 증가와 장애인 인구의 증가로 인해 재활훈련기의 수요가 증가하고 있고, 재활훈련기와 사용자간의 제공받아야 할 서비스에 대한 평가 요소의 요구가 커지고 있다. 본 연구에서는 재활훈련기 디자인 평가에 있어서 평가 방안을 모색하기 위해 디자인 평가를 위한 기본 요소를 파악하고 이를 통하여 재활의료전문가, 의공학자, 디자이너들의 토의 및 분석, 실험을 통하여 새로운 평가 요소들을 도출하였다. 연구의 결과는 다음과 같이 요약된다. 첫째, 기존 디자인 평가 요소들을 수집, 분석하여 10가지의 재활훈련기 디자인 평가요소와 44개의 세부 평가항목을 구축하였다. 이는 앞으로 재활훈련기를 디자인하는데 있어서 중요한 평가 기준이 될 것이다. 둘째, 헬스케어 재활훈련기 디자인 개발 시 고려해야 할 디자인 평가요소로는 사용성, 인지성, 안전성, 학습성, 운동성, 내구성, 경제성, 공간성, 심미성, 환경성의 10가지 디자인 평가요소가 있다. 셋째, 환경성, 공간성, 인지성, 사용성, 경제성, 심미성의 디자인 평가요소는 제품디자인에서 공통적으로 고려해야 할 요소들이고, 학습성, 안전성, 운동성, 내구성의 요소는 재활훈련기 디자인 평가요소에서 매우 중요하게 고려해야 할 요소이다. 넷째, 재활훈련기 디자인 평가요소는 제품디자인요소에서 중요하게 고려되는 환경성, 공간성, 인지성, 사용성, 경제성, 심미성에 학습성, 안전성, 운동성, 내구성을 의 요소를 더해 중요하게 생각한 것이 기존 제품디자인 평가요소와 재활훈련기 디자인 평가요소의 차이점이다. 본 연구에서는 10개의 재활훈련기 디자인 평가요소와 44개의 세부 평가항목 구축에 대한 연구를 진행하였다. 이는 전체적인 재활훈련기 디자인 평가요소만을 연구한 것으로, 향후연구에서는 시 제품 제작을 통하여 평가요소들을 실제 재활훈련기 디자인에 적용해 보고, 미진한 점들을 수정 보완할 예정이다.

  • Common utility tunnel is essential to the daily lives of people underground utilities (electricity, gas and supply facilities such as water, communication facilities, sewer facilities, etc.) to improve the appearance by co-acceptance and disaster prevention, important for the conservation of the city's population was concentrated road construction the city-based facilities. There is recognition of the importance of the various supply treatment facilities in common utility tunnel as infrastructure to accommodate joint according to the city expanded, the demand for infrastructure. In this paper, a cost-benefit analysis using a one-time occurrence, without simply relying on cost or current cost, project manager for the city-dimensional feasibility study conducted, the user level of the maintenance costs and user costs, including social costs items from various angles can be investigated and proposed a mechanism of economic feasibility common utility tunnel. Evaluation of the proposed technique is cost-benefit and cost caused by installing common utility tunnel the existing pipeline area - was investigated by the benefit analysis, extended and repeated common utility tunnel installation depends much affected by the excavation, so users of reducing the number of repeat excavation convenience can be seen that this occurs.

  • There are two types of expensive measuring instruments currently on the market shape measurement and roundness measurement instruments. As they are very expensive, from tens of millions to more than 200 million won, buying them is economically burdensome for small companies or individuals. Therefore, in order to integrate the shape and roundness measurements into a single transfer device, this study aimed to reduce the trial and error by 3D modeling and simulation, and we confirmed the feasibility of operation. Based on these outcomes, a prototype hybrid measuring instrument was fabricated. As a result of performance evaluation and comparative evaluation, we verified the feasibility of implementation and application of the hybrid measuring instrument.

  • 정부는 대규모 사회간접자본시설에 대한 무분별한 추진을 막기 위해 사업의 타당성조사 뿐만 아니라 설계, 시공, 완공 시점에 사후평가를 실시하고 있다. 하지만 이러한 사후평가는 사전사후평가를 위한 평가항목과 분석방법이 모호하여 실효를 거두지 못하고 있다. 특히 철도사업은 철도사업의 종류와 철도의 종류에 따라 평가항목이 상이하여 사후평가항목과 분석절차가 차별화되어야 한다. 본 논문은 철도건설사업의 사후평가항목을 도출하고 데이터 수집 및 분석방법을 표준화하는 방안을 제시하고 있다. 구체적으로는 철도사업별로 공통평가항목과 특수평가항목을 도출하였고 이를 분석하는 방법으로 GIS기법을 제시하였다.

  • The purpose of this research is to evaluate the feasibility of outsourcing test/inspection activity in construction work. This research conducted a questionnaire of interested parties as well as a survey by Analytic Hierarchy Process (AHP) with experts on quality control. For the evaluation by AHP, five criteria were adopted and a number of pair-wise comparisons were conducted through two stages. Finally, the weighting coefficient to approve the outsourcing was calculated at 0.606 and it therefore appeared more reasonable to permit rather than prohibit outsourcing. According to the AHP result, it was found that outsourcing would be necessary to enhance the objectivity and specialties of quality testing and inspection, even though somewhat undesirable in terms of enhancing a sense of responsibility and systemically conducting the testing and inspection.

  • This paper aims to analyze the economic feasibility and investigate the possibility of elastic seismic design of wind-designed highrise concentrically braced frames considering change of mechanical properties of Korean steel under the strong wind and the low seismicity in Korea. To this end, first, highrise concentrically braced frames were designed considering strong wind load. And then, analyses of the economics of them were performed. The seismic performance evaluation of wind-designed highrise buildings was conducted using the response spectrum analysis procedure. Analysis results show that it is possible to save up to approximately 90% of the amount of steel on the 10% increase in steel strength without serviceability. However, with serviceability, the design sectional area of the steel with relatively high strength tends to increment considerably because of the lateral stiffness due to reduction of the inertia moment and so on. This point might apply to limitation of the steel with high tensile yield strength.

  • This study aims to examine the usefulness on the Evaluation Process for the Feasibility & Priority of A Certain Public Projects. and the Methodology used AHP(Analytic Hierarchy Process) which used pairwise comparisons of the alternatives and criteria for solving discrete alternative multicriteria decision problems. In this paper, we present a similar phenomenon, rank reversal problem, when we apply the AHP to group decision making process. The problem is identified by an example problem in that the previous rank order of Public Projects choices. we also present three different methods to prevent the undesirable characteristic of the original AHP in appling to Decision Making Process.

  • We designed a conceptual model of the 2.3-BDO dehydration process using a hydroxyapatite-alumina catalyst and estimated its economic feasibility to predict the appropriate range of the purchase price of 2,3-BDO on commercial scale. The conceptual design and economic analysis can offer valuable information for the industrial application of 2,3-BDO because the most relevant studies have limitation in laboratory scale. Furthermore, the adequate range of 2,3-BDO price, in which the process has profitability, was investigated with the current market prices of 1,3-BD. The investigated price in terms of 2,3-BDO dehydration can pertain to estimation of the economic feasibility in 2,3-BDO production process.

  • 규제당국은 유해 물질 배출을 저감 하는 규제를 시행하면서, 규제 이행에 따른 다양한 활동의 편익/비용 비율로 그 타당성을 제시한다. 그리고 비율 산정과정에서 규제 관련 속성의 중요도 가중치를 반영한다. 그런데, 전문가들은 가중치 설문 응답에서 애매함을 보이고 있으며, 정확한 의사 결정을 위해서는 이를 제거해야 한다. 본 연구에서는 이를 위한 퍼지-계층화 방법론을 이용하여 타당성여부를 적용하고, 이를 2019년 11월 시행된 우리나라의 '배출 저감 계획'규제 타당성 평가에 적용하였다.
