  • The Cross-impact Hierarchy Process (CHP), an extended model of the Analytic Hierarchy Process(AHP) which is linked to Cross Impact Analysis(CIA), is a powerful decision making tool to assist in the ranking of large number of dependent technological alternatives. In this paper, we will describe an application of the CHP to the aerospace industry. We here conducted a questionnaire survey for S company that is one of the representative aerospace companies in Korea. A questionnaire was designed to obtain both the priority with dependence (the CHP priority) and the priority with independence (the AHP priority) in order to compare the priority derived by each of two methods. The hierarchy in this case study is concerned with priority setting for R&D area to ensure dependent aerospace design technology of the company, The result shows that there exists the difference hard to neglect between the final priorities gained by two methods.

  • 이 논문은 대학서열에 따른 임금차이를 학벌 프리미엄으로 정의하고 1982년, 1992년, 2002년 대학졸업자들의 노동시장 경력과 학교생활에 대한 정보를 담은 「교육-노동시장 생애경로조사」를 바탕으로 학벌 프리미엄의 시대별 경력별 변화를 살펴본다. 학벌 프리미엄은 졸업연도와 졸업 후 시점에 따른 다른 양상을 보인다. 대체로 졸업 후 시간이 지남에 따라 학벌프리미엄이 감소하는 경향이 있으며 경력이 오래될수록 학벌 프리미엄은 감소하는 모습을 보인다. 또한 입학성적을 고려하였을 경우 1992년 졸업자들의 학벌 프리미엄은 사라지지만 2002년 졸업자들의 학벌프리미엄은 입직 시는 물론 졸업 후 7년 지난 시점에서 남아있는 것으로 나타났다. 학벌 프리미엄에서 보이는 세대별 차이에 대해서는 적어도 부분적으로 대학 수, 대학진학률, 입학성적과 대학서열 사이의 관계 등으로 설명할 수 있는 것으로 보인다.

  • The purpose of this study is to investigate significant differences of structural knowledges among the groups(high, middle, low) when the 6th grade subjects structured the concepts of the plane figures, triangle and quadrangle, by concept maps, and to analyse the features of concept maps according to hierarchy. For this purpose, the following two research contents were investigated: 1. Investigating significant differences of structural knowledge in the concepts of the plane figures using concept maps among the groups(high, middle, low). 2. Analysing the features of concept maps according to hierarchy. The structural knowledges represented on the concept maps of triangle and quadrangle which were drawn by the subjects were analysed by propositions, hierarchies, and cross-links. Subject-self Reports about how to make the concept maps were used to analyse the features of concept maps according to hierarchy. The conclusions drawn from the results were as fellows: First, there were significant differences among the groups in proposition links. Second, there wasn't my significant difference among the groups in hierarchy. Third, there were significant differences among the groups in cross-links, and Fourth, the results of analysing the concept maps by hierarchy showed that there were differences among the individuals in constructing the knowledges.

  • ITS (Intelligent Transportation System) has been more popular but ITS project managements remain complex because of diverse stakeholders and multidisciplinary processes of ITS. The multidisciplinary process enforces specialized competencies on ITS project managers comparing to other system integration project managers. In this paper, we derived core competencies of ITS projects from previous researches, built the hierarchy of the competencies, and employed AHP (Analytic Hierarchy Process) surveying ITS project managers and auditors with the hierarchy. Finally, we analyzed the difference of evaluation model on ITS project manager between project managers and auditors using Mann-Whitney U test. Additionally we suggest a method of building MECE (Mutually Exclusive and Collectively Exhaustive) structure for AHP using the HoQ (House of Quality). We expect our model to give some inspirations for raising capable ITS project managers and selecting a proper project manager for an ITS project.

  • 본 논문은 알미르 슈타트 극장 이후에 나타나기 시작하는 공간의 비위계적 구성(non-hierachical arrangement)으로 평면계획이 이루어진 SANAA의 작품들을 선정하여 공간구문론(space syntax)에 의한 정량적 분석을 시도하였고, 외형적으로 보여지는 평면구성의 비위계성이 정량적 수치값으로는 어떻게 나타나는지를 분석하였다. 분석결과 다음과 같은 결론을 얻었다. 첫째, 외형상 보여지는 비위계적 평면구성을 보이는 SANAA의 각 공간들은 정량적 수치값의 분명한 차이를 보이고 있으며, 외형적으로는 잘 드러나지 않는 공간의 위계 차이가 분명히 있음을 확인할 수 있다. 둘째, 통합도(Integration)값이 높은 공간들은 연결도(Connectivity)값도 대부분 함께 높음을 알 수 있었는데, 비위계적 평면구성의 위계성을 부여하는 방법으로 공간의 출입구 개수를 늘리거나, 실의 크기와 위치조정을 통해 숨겨진 위계성을 부여하고 있음을 알 수 있다. 셋째, SANAA는 그리드 형태의 평면구성에서 내부 복도 대신에 외곽부 복도를 이용하여 접근성 문제의 해결을 시도하고 있으며, 방과 방 사이의 오픈 코트 공간은 자연채광과 환기를 제공함과 동시에 공간의 숨겨진 위계성을 조절하는 장치로 채택되고 있음을 알 수 있다.

  • Objectives: This study is to understand and develop Acupuncture treatment in Korean Medicine(韓醫學). Methods : Firstly, the definitions of Acupuncture Prescription(鍼 處方) and Methods of Acupuncture Therapies(鍼法) were clarified. Secondly, the results from the researches of previously existing Acupuncture Prescriptions(鍼 處方) were analyzed. Results & Conclusions : Acupuncture Prescription(鍼 處方) represents the results achieved from combining Acupuncture Points(腧穴) according to the symptoms of diseases. Methods of Acupuncture Therapies(鍼法) denote methodologies for proposing Acupuncture Prescriptions(鍼 處方) which were accomplished by combining Acupuncture Points(腧穴) based on a specific theory. The existing methods of combining Acupuncture Points(腧穴) derived from the analysis of Acupuncture Prescription (鍼 處方) have a meaning in suggesting a direction for acupuncture treatments. However, deficiencies still exist to restore the absence of universality and objectivity in acupuncture treatment. Researches on Methods of Acupuncture Therapies(鍼法) based on the principle are required accordingly. The concept of hierarchy exists in Acupuncture Prescription(鍼 處方) and it ranks Acupuncture Points(腧穴) as primary and secondary according to the indications of the Acupuncture Points(腧穴). Since there is the time difference in needling process, the concept of hierarchy is fulfilled through the needling procedure.

  • The Extraposition phenomenon in English has been analyzed mainly through two approaches: a derivational approach under the Principles & Parameters framework (P&P) and a representational approach under the early Minimalist framework (MP). The first one tries to understand the phenomenon as a result of the movement of a Big Subject first to the end of a sentence which is then followed by the insertion of an expletive 'it' to the empty Subject position. On the other hand, the second one tries to understand it by way of assuming a Big Subject originally base-generated at the end of a sentence which is followed by the insertion of an expletive 'it' to the empty Subject position. The two approaches, however, are not free from theoretical defects at all: the full derivational approach was under controversy in terms of (1) the failure of the Binding Theory and (2) its inability to suggest anything about the marginal reading issue. On the while, the representational approach has been argued (1) to violate the thematic hierarchy that should be kept in D-structure, and (2) to be also unable to suggest the slightest difference in marginal reading issue as the first one. In this paper I focus mainly on analyzing the 'It'-Extraposition phenomenon in the Optimality Theory. I will show that by way of (i) some newly developed constraints such as Subj., and AHSubj. and (ii) a constraint hierarchy of Subj.>>AHSubj., the controversies of 'It-Extraposition' such as (1) the analysis of construction and (2) the very closely related issue of 'marginal reading issue' can be explained properly.

  • In order to present the enhancement direction for the military administrative facilities, that can satisfy the user demands and achieve cost-effectiveness the goal of public projects, this research analyzes the features of functional spaces using Analytical Hierarchy Process(AHP). Basically, the scope is selected to four facilities commander office, private office, public office, and meeting room, because they have an effect on military administrative facilities. Since the space is established by a combination of their own functions, this research begins with an analysis of functional spaces of military administrative facilities, which is verified through literature review and interview with expert. Thereafter, an AHP survey is conducted to military personnel to analyze the priority of functional spaces and to re-classify the functional spaces of each Military administrative facilities. Resultingly, the difference of functional spaces preference according to ranks and facility type are identified. Even though the same military facilities, it means that user satisfaction is different. Therefore, user satisfaction should be considered for each facility at the construction plan. It can minimize overlapped and unused spaces, which can help ensure cost-effectiveness. Consequently, this research suggested the methodology and the process that can take user satisfaction and can support the enhancement of military facilities standards.
