철도선로구간의 노후도는 궤도, 노반, 교량, 터널 등 요소시설의 노후도로 결정되며 궤도의 선형 또한 선로구간 노후도에 영향을 준다. 본 논문에서는 계층구조분석(analytic hierarchy process: AHP)과 자료포락분석(data envelopment analysis: DEA)을 활용하여 선로구간의 노후도를 평가하는 방법을 제시한다. AHP는 다수의 전문가들이 평가하는 각 요소시설의 중요도를 체계적으로 파악할 수 있도록 해준다. 요소시설에 대한 중요도는 전문가에 따라 달라질 수 있다. DEA는 선로구간 요소시설의 중요도 가중치 범위를 체계적으로 반영하여 선로구간의 노후도를 평가할 수 있도록 해준다.

공공과 민간부문에 있어 다양한 평가기준에 대하여 집단의사를 반영할 수 있고 주관적이고 객관적인 의사결정변수를 계층적 평가구조에 따라 모두 고려하여 종합평가할 수 있는 집단의사결정 지원시스템으로 AHP(Analytic Hierarchy Process:계층분석법)이 주목받고 있으며, 이론적으로도 높이 평가되고 있어 현존하는 의사결정기법 중 가장 광범위하게 활용되고 있다. 본 연구에서는 도로투자우선순위를 결정하는데 있어 다기준분석기법으로 AHP를 활용토록 하였으며, 이제까지 경제성외에 소홀하게 다루어졌던 환경적인 측면, 주민생활과 지역균형발전 등을 반영한 종합평가를 실시하기 위하여 평가항목별 가중치를 설정하고 각 항목별 평가지표에 대한 도로투자사업 평가배점의 기준을 마련토록 하였다. 또한 AHP를 적용함에 있어 사례 분석할 경상북도 도로투자사업과 같이 평가대상노선이 많을 경우 쌍대비교에 의한 우선순위 평가가 불가능하기 때문에, 상위 평가항목에 대해서는 상대평가법에 의해 가중치를 구하고, 각각의 하위 목적요소에는 평점에 의한 절대평가법을 조합하여 도로투자우선순위를 결정할 수 있는 AHP의 분석방법론을 제안토록 하였다.

Recently, habitat fragmentation and shrinkage has occurred because of increased road construction. As a measures mitigating the adverse effect such as eco-island by road construction, Korea has been installed eco-corridors since 1995. Using the Analytic Hierarchy Process (AHP), this study analyzed the importance of assessment items and the criteria to determine which areas require eco-corridors the most. First, related literature reviews, preliminary surveys, and expert interviews were carried out to develop assessment items and criteria for constructing the hierarchy. Second, experts were surveyed in order to determine the relative importance of the assessment items by applying the AHP. As a result, it found that the restoration of the ecological network was the most important assessment item, followed by wild animal resources in the Level 3. In the Level 4, the eighteen items were ranked in the order of their relative weight and it was found that the 'Baekdudaegan Mountain Range (0.189)' was the highest ranked item. Therefore, this approach can be applied to effective selection of the priority areas in planning eco-corridors in the national scale.

A karst collapse, as a natural hazard, is totally different to a normal collapse. In recent years, karst collapses have caused substantial economic losses and even threatened human safety. A risk assessment model for karst collapse was developed based on the fuzzy analytic hierarchy process (FAHP) and grey relational analysis (GRA), which is a simple and effective mathematical algorithm. An evaluation index played an important role in the process of completing the risk assessment model. In this study, the proposed model was applied to Jiaobai village in southwest China. First, the main controlling factors were summarized as an evaluation index of the model based on an investigation and statistical analysis of the natural formation law of karst collapse. Second, the FAHP was used to determine the relative weights and GRA was used to calculate the grey relational coefficient among the indices. Finally, the relational sequence of evaluation objects was established by calculating the grey weighted relational degree. According to the maximum relational rule, the greater the relational degree the better the relational degree with the hierarchy set. The results showed that the model accurately simulated the field condition. It is also demonstrated the contribution of various control factors to the process of karst collapse and the degree of collapse in the study area.

Purpose: This study aimed to derive the elements for effectively improving the management of emerging infectious diseases in the emergency room in large general hospitals. Methods: This research involved an analytic hierarchy process analysis of 10 experienced nurses working in a large general hospital located in the Seoul metropolitan area. The weighted values of the criteria for evaluating the importance of the management elements of patients with emerging infectious diseases in the emergency room of large general hospitals were derived using an analytic hierarchy process survey. Results: The results of the analytic hierarchy process analysis showed that experts considers responsiveness (0.291) as most important with respect to the criteria for the policy for isolation and control of infectious patients. The order of importance of the criteria for the policy for isolation and control of infectious patients were as follows: responsiveness (0.291), economical efficiency (0.257), feasibility (0.242), and sustainability (0.209). Subsequently, the weighted values of the management of the policy elements were determined based on the derived importance of the criteria mentioned above. These were, in order of priority, the construction of communication channels with the government authorities when dealing with emerging infectious diseases (15.9%), the equipment and provision of personal protective equipment to protect nurses from infection and dissemination of material (14.6%), and the operation of the isolation room and patient separation systems (14.1%). Conclusion: This study suggests critical strategies for infection control during a pandemic of emerging infectious disease.

Many LCD manufacturers continue to develop the technologies of LCD manufacturing processes for the reduction of production cost, power consumption and high-resolution. The LTPS (Low Temperature Polycrystalline Silicon) crystallization technology is important for rearranging the internal structure of liquid crystal grain by adding certain energy to amorphous silicon and turning it into poly-silicon in order to manufacture LCD with better performance. We consider 14 existing technologies of LTPS crystallization in the LCD manufacturing and present an intelligent analysis methodology using patent map and AHP (Analytic Hierarchy Process) analysis for determining an optimal LTPS crystallization technology. By using patent map analysis, we easily understand the development process and mega-trend of LTPS crystallization technologies and their relationship. By using AHP analysis, we evaluate 14 LTPS technologies. Through the use of proposed methodology, we determine the Continuous Wave Laser Lateral Crystallization technology as an optimal one.
