사서함 구조에서 메시지 서비스를 위한 중요한 구조적 메커니즘은 메시지 객체들을 콘텐츠에 따라 그룹 클래스 계층 구조를 구성하는 것이다. 본 논문에서는 응용 도메인에서 많은 구조적인 메시지 객체들을 클러스터링하기 위한 $\alpha$-cut 기반의 genealogy 그룹화 방법을 제안한다. 제안된 방법은 의미적 유사 관계와 퍼지 유사 관계를 이용하여 관계성을 결정하고 search() insert(), hierarchy()의 연산을 이용하여 그룹화 구조를 수행한다. 이러한 구조는 그룹과 관련된 작업을 쉽게 처리해주고 질의응답 객체 식별, 유사성 발견 등을 쉽게 해준다. 따라서 제안된 사서함 구조는 그룹화 생성을 통해서 사용자들에게 메시지객체를 효율적으로 서비스하고 관리하는 기능을 제공한다. 그리고 제안된 기법의 성능을 알아보기 위해 5600개의 메시지 객체를 이용하여 non-grouping, BGM, RGM, OGM 방법과 비교 분석한다.

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.

We propose a method using QFD for design the hierarchical structure of AHP. This method provides definition for each area of House of Quality and design the hierarchical structure of the bottom-up QFD/AHP in which the upper hierarchy is designed through the classification of common characteristics with a focus on the lower hierarchy. Finally, we apply it to the development of an evaluation index for selecting heavy lifting service providers. This study has significance as the first instance of designing the archical structure of AHP after objectively verifying whether MECE condition, the basic requirement for AHP design, is satisfied.

In order to enhance the aviation industry in Korea, many strategies have been published by some researchers as well as the government. However, considering the constrained conditions in real, since the ranking of their importance has not determined yet, they are difficult to be implemented by decision makers. Therefore, in terms of their demand for deciding the significance of strategies, the evaluation model of this paper was developed. In this study, the Cross-impact Hierarchy Process(CHP), an linked model of both the Analytic Hierarchy Process(AHP) and Cross Impact Analysis(CIA), was selected as the best model. That is because the strategies are not independent from each other, and one strategy can affect the others depending on its realization, which can be considered in CHP. To achieve our objective, at first, the strategies were categorized and arranged according to the evaluation structure. Secondly, the parameters such as conditional probability and weights were estimated from the survey conducted by 16 experts in the aviation field. Lastly, the result of the assessment were discussed, and further studies were suggested.

Analytical Hierarchy Process (AHP) is a famous method amongst Multi Criteria Decision Making (MCDM), set up by Saaty in 1980. AHP can be determined as a methodology of hierarchical analysis following reasonable decision making with make simpler a difficult crisis. Decision making in systems of Safety management concerned multipart challenges. AHP is process for get better the composite decisions understanding with analyzes of the problem in a structure of hierarchy. The integration all of applicable decision criteria, their pair wise judgment permits the decision maker to establish the trade-offs amongst objectives. In recent years, Malaysian's economy and infrastructure development have significantly and rapidly risen. The construction industry continues to play a major role in this development as many construction activities have been carried out to meet the high demands of the expansive market. However, the construction industry has faced a wide range of challenges, one of which is the frequent occurrences of accidents at the workplace. An effective safety program can substantially reduce accidents because it can help management to build up safer means of operations and create safe working environments for the workers. Furthermore, by having an effective safety programs, good safety culture can be embedded in organization because it can encourage mutual cooperation between management and workers in the operations of the programs and decisions that affect their safety and health. The focus of this research is development methodology of Analytics Hierarchy Process (AHP) in construction safety factors and investigates the levels of some effective elements in SMS in Malaysian construction industries.

정성적인 지질정보들의 연계 해석을 위해서는 자료들의 중요도에 따라 정량화가 선행되어야 한다. 이 연구에서는 계층분석과정을 사용하여 정성적 자료를 정량화하였다. 토목, 교통 및 지질관련 전문가 집단(30명)을 구성하여 선형토목구조물 설계에 필요한 지질 및 수리지질에 대한 조사항목을 설문하고 분석하였으며, 이에 따라 조사항목들에 대한 계층구조를 4단계로 구성하였다. 각 단계별 요소에서 선형토목구조물의 안정성에 가장 중요한 요인으로 작용하는 요소는 단층 구조이며, 그 중요도가 46%(0.456)로 나타났다. 단층구조 다음으로는 엽리/층리(0.165), 선구조선(0.144), 지하수(0.124), 암상(0.111) 등의 순으로 중요도를 갖는다.

PURPOSES : This study prioritizes potential technology for establishing a safe work zone environment on roadways. We consider almost all conceivable technologies that enable mitigation of unexpected accidents for both road workers and drivers. METHODS : This study suggests a methodology to set the priority of potential technology for establishing a safe work zone environment by using the analytical hierarchy process (AHP). For this purpose, the AHP structure was first developed. Thereafter, a web-based survey was conducted to collect experts' opinions. Based on the survey results, weights associated with the relevant criteria of the developed structure were estimated. With the consistency index (CI) and consistency ratio (CR), we verified the estimated weights. In addition, a sensitivity analysis was performed to confirm whether the estimated weights were reliable. We finally proposed the priority for potential technology for establishing a safe work zone environment on roadways. RESULTS : In the first level, safety technology has the highest priority, and real-time information delivery for work zone, hazard warning for drivers, and temporal automated operation for traffic facilities were selected in the second level of hierarchy. CONCLUSIONS : The results imply that establishing the priority will be useful to establish a future road map for improving the work environment for road workers and drivers by employing appropriate protection facilities and developing safety systems.

The purpose of this study is to investigate items for improving environmental education in elementary school for the more efficiency policies of environmental education. In this study, we investigated the relative importance of each items through Analytic Hierarchy Process for the various groups of the expert who is related with environmental education. We made hierarchical structure for efficiency education through brainstorming process. The hierarchical structure consisted of 3 high-level items and 8 low-level items. The questionnaires were distributed to 4 groups with 187 experts. After the consistency test of returned questionnaires, we gained 60 available questionnaires of experts. According to the generalization results of all groups, "The pro-environmental attitude of the teacher" is the most important. The second important thing is "The pro-environmental attitude of the schoolmaster" and the third is "Experiential learning and on-the-spot study concerning environment". And the following are "Budget for environmental education" and "Environmental education in discretionary activity", "Teaching materials for environmental education", "The cultivation of the experts on environmental education", "Environment event in school" in order. As the result, we have to intensify the pro-environmental attitude of the teachers and schoolmasters and develop experiential learning and on-the-spot study programs concerned environment to improve environmental education. At the same time, we need the more politic support related with budget for environmental education.

이 연구는 지식유형에 따른 표상 차이를 확인하기 위해서 범주지식과 각본지식의 위계성과 전형성에 대한 점화효과를 측정하였다. 실험 1에서는 상위개념을 점화단어로 제시하고 하위개념을 목표단어로 제시한 다움 목표단어의 어휘판단시간을 측정하였다. 그 결과, 범주지식은 전형단어가 비전형단어보다 반응시간이 빨랐지만, 각본지식은 두 조건간의 차이가 없었다. 실험 2에서는 하위개념을 점화단어로 제시하고 상위개념을 목표단어로 제시한 다음 목표단어의 어위판단시간을 측정하였다. 범주지식이 각본지식보다 반응시간이 빨랐으며, 두 지식 모두 전형성 효과는 관찰되지 않았다. 이러한 결과는 범주지식은 전형성에 따른 위계구조를 구성하지만 각본지식은 범주지식에 비해서 위계성과 전형성이 약회된 구조로 표상될 가능성을 시사하는 것이다.
