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.

The purpose of this study is to develop a mathematical assessment and correction materials according to the mathematics learning hierarchy. The scope of the study is set to 'function' in 7th grade of middle school. The researchers developed a draft of the mathematical assessment and correction materials based on the mathematics learning hierarchy through the pilot test and the expert review. Using the results of the expert review, the researchers modified and supplemented the math assessment and correction materials to produce the final version. The mathematics assessment and correction material developed in this study is expected to build an effective guidance system for students with mathematics deficits. In addition, by presenting a mathematical assessment and correction materials to the teachers in the field, it is possible to reduce the effort for the management of underachievers and to provide guidance for the education of students with a lack of math learning.

이 연구는 명성에 대한 진화심리학적 접근을 시도한다. 학제적 분석을 통해 명성에 대한 새로운 이해와 피알이론개발의 토대를 마련하는 것이 목적이다. 그 첫 단계로 Tall Puppy Scale을 활용해 유명인에 대한 한국인의 일반적 태도를 측정한다. 유명인에 대한 지지보상과 몰락선호를 검증하고 한국의 결과를 호주의 것과 설문을 통해 비교한다. 성공한 유명인들에 대한 한국인들의 태도는 호주인들보다 첨예했다. 포용성은 낮았고, 공격성은 높았다. 보상선호와 몰락선호를 함께 고려했을 때 한국인의 명성서열심리는 호주인들보다 6배 이상 공격적이었다. 명성서열심리를 설명하는 제1변수는 자존감이었다. 자존감이 높은 사람들은 성공한 유명인에 대해 관대하고 그들의 사회적 필요성에도 공감하고 있었다. 남성보다 여성이, 나이가 많을수록, 친구가 적을수록, 의사표현에 소극적일수록, 그리고 느끼는 경쟁이 치열할수록 유명인에 대한 공격성향이 강한 것으로 드러났다. 개인의 자존감은 명성의 진화심리를 이해하는 핵심 척도였다.

이동 애드혹 네트워크(MANET)는 기반 네트워크 없이 구성되어 원격지의 환경에 대한 정확한 모니터링 또는 제어를 가능하게 한다. 이러한 MANET에서는 정적인 네트워크에 비해 토폴로지가 자주 변하므로 이동성을 고려한 에너지 효율적인 라우팅 프로토콜이 요구된다. 이를 위해 본 논문에서는, 상황인식 기반의 적응적이며 계층적 클러스터링 기법인 CACH(Context-aware Adaptive Clustering Hierarchy)를 제안한다. CACH는 적응적 라우팅 기법과 비적응적 라우팅 기법을 융합한 하이브리드 라우팅 방식을 분산 클러스터링 기반으로 구성하였다. CACH는 또한 토폴로지 변경에 대해 상황인식을 기반으로 하여 적응적으로 토폴로지의 계층구조를 수정하는 새로운 기법을 이용하여, 네트워크의 수명을 연장하고 지연시간을 줄일 수 있다.

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.

Noun phrase coordination is an extremely productive phenomenon. Based on an observation that conjuncts tend to denote semantically related concepts, we collect four hundred thousand pairs of conjuncts from the British National Corpus, in an attempt to build an is-a hierarchy of English noun concepts. The modifiedness patterns of the two words in these pairs point to three distinct semantic relations: sibling, cousin, and ancestor-or-ancestor' sibling. The process of finding them and how these pairs are used to motivate groups of quasi-synonyms and then to locate the hypernyms are discussed.

In human reliability analysis, dependence assessment is an important issue in risky large complex systems, such as operation of a nuclear power plant. Many existing methods depend on an expert's judgment, which contributes to the subjectivity and restrictions of results. Recently, a computational method, based on the Dempster-Shafer evidence theory and analytic hierarchy process, has been proposed to handle the dependence in human reliability analysis. The model can deal with uncertainty in an analyst's judgment and reduce the subjectivity in the evaluation process. However, the computation is heavy and complicated to some degree. The most important issue is that the existing method is in a positive aspect, which may cause an underestimation of the risk. In this study, a new evidential analytic hierarchy process dependence assessment methodology, based on the improvement of existing methods, has been proposed, which is expected to be easier and more effective.

The purposes of this study were: 1) to show the item difficulty hierarchy of walking/moving construct of the International Classification of Functioning, Disability and Health-Activity Measure (ICF-AM), 2) to evaluate the item-level psychometrics for model fit, 3) to describe the relevant physical activity defined by level of activity intensity expressed as Metabolic Equivalent of Tasks (MET), and 4) to explore what extent the empirical activity hierarchy of the ICF-AM is linked to the conceptual model based on the level of energy expenditure described as MET. One hundred and eight participants with lower extremity impairments were examined for the present study. A newly created activity measure, the ICF-AM using an item response theory (IRT) model and computer adaptive testing (CAT) method, has a construct on walking/moving construct. Based on the ICF category of walking and moving, the instrument comprised items corresponding to: walking short distances, walking long distances, walking on different surfaces, walking around objects, climbing, and running. The item difficulty hierarchy was created using Winstep software for 20 items. The Rasch analyses (1-parameter IRT model) were performed on participants with lower extremity injuries who completed the paper and pencil version of walking/moving construct of the ICF-AM. The classification of physical activity can also be performed by the use of METs that is often preferred to determine the level of physical activity. The empirical item hierarchy of walking, climbing, running activities of the ICF-AM instrument was similar to the conceptual activity hierarchy based on the METs. The empirically derived item difficulty hierarchy of the ICF-AM may be useful in developing MET-based activity measure questionnaires. In addition to convenience of applying items to questionnaires, implications of the finding could lead to the use of CAT method without sacrificing the objectivity of physiologic measures.
