형용사는 감성 및 감정검색을 위한 색인에서 주로 사용된다. 이를 위해서는 형용사의 개념관계를 파악하고 표현하는 것이 중요한 일이다. 본 연구에서는 형용사의 개념관계를 표현하기 위하여 형용사의 특성, 관련 개념구조를 고찰하고, 아울러 구조화, 관계, 표시방법, 배열 등을 고려하여 형용사 시소러스를 설계하였다.

Bridge design is a problem-solving process whose level of design quality strongly depends on how to relate design constraints with feasibile design objectives in conceptual design stage. This paper has focused on how to create bridge shapes using creativity toward better looking bridge appearances in conceptual design stage. The term creativity in this study does not refer to the creation of something from nothing but to the reorganization of existing concepts. Such creativity includes not only enlarging the number of structural forms which is established based on the relationship between form and statics but also combining bridge design with artistic components like an architectural style. Also, this study has investigated the usefulness of graphic statics as a structural analysis tool showing the analysis results visually to generate bridge forms in conceptual design stage. It is expected that the proposed way of generating bridge forms in this study to be used not only for practical purpose but also for educational purpose regarding the aesthetic bridge design serving as a new education paradigm.

It is not too much to say that, at the beginning of engine development, the most important areas for a good engine concept design is the lubrication system design. So, between right after finishing concept design and before procuring the engine, it is necessary to carry out the system lubrication analysis for the initially designed lubrication system and the related lubricating parts. Therefore, in this paper, it is to describe the results of a design review carried out the numerical net work analysis on the engine bearings and the lubrication system of an initially designed 2.0 L DOHC engine.

UML is a very good description of object-oriented concepts and supports the use case diagram for analyzing the system functionality, the class diagram for representing the domain object in the analysis step, the sequence diagram for connecting the action in the class. The visual-based, object-oriented LabVIEW OOP is an intuitive design tool that can be executed at the same time as a development tool. However, even the system developer using LabVIEW OOP is needed known about the object-oriented concept in the design stage. In this paper, we suggest the method to applying the UML modeling diagram to LabVIEW OOP design.

The performance analysis code has been developed for vertical take-off and landing(VTOL) UAV which can be utilized as a trade analysis tool in the pre-conceptual design phase. The UAV requires VTOL capability and high speed cruise performance. The main logic of this performance analysis code is to estimate performance parameters of each mission segment by mission fuel weight iteration. The reliability of this performance analysis code is discussed by comparing the data of existing dual flight mode VTOL UAVs such as Boeing CRW and Bell Tilt Rotor.

The purpose of this study is analyze the impact on users' cognition of design concept, satisfaction of design concept, adapted park space, and effect of design concepts on park use satisfaction. The study sites are Central Mountain Park and Lake Park in Gwanggyo New Town, Suwon. We analyzed importance-satisfaction of park facilities in the park and preference-satisfaction of park. The results of this study are as follows. First, generally users visit the park as a family unit. Second, trails got high scores in importance-satisfaction of park facilities. Third, park users' satisfaction received a high score generally, but it doesn't show statistic significance with users' cognition of design concept. Fourth, cognition of the two parks' design concept and design strategy got a high score - over three points on average - based on the 5 - point Likert scale. However, upon analysis of users' cognition of design concept and satisfaction of design concept adapted park space, there is no statistic significance. Therefore, we noticed that the park's design concept had an effect on park users' satisfaction; rather, personal preference and satisfaction of users had more impact on satisfaction. On the other hand, this study was limited in that we didn't survey across all four seasons and had few target areas. But it has some significance in that we used a visual documentation, attaching existing photos including design concept, to increase users' understanding. Also, we directly asked about the parks' user design concept and strategy.

본딩은 전기/전자 시스템뿐만 아니라 연료, 엔진, 비행제어, 유/공압계통 등에서도 안전한 전기적인 운용을 하기 위해서 필요하다. 항공기 개발에서 본딩은 설계시부터 요구조건을 두어 엄격히 관리해야 하며, 제작시에도 제시된 요구조건에 맞게 본딩을 해야 한다. 항공기의 전기/전자계통 설계시 요구성능과 항공기 및 운용자의 안전성 확보를 본딩 계통의 설계목표로 설정하고, 세부적인 본딩 요구조건과 유사기종의 설계개념을 보완하여 현실적으로 적용가능한 적용분야별 본딩 설치 및 설계 요구조건을 정립하는 것이 매우 필수적이라고 판단된다. 이 글에서는 항공기 설계시 고려해야 되는 본딩 일반요구조건에 대하여 기술해 보고자 한다.

Recent diversification of project delivery systems coupled with increasing mega-projects requires highly advanced construction management techniques. Among those techniques, procurement and design management are recognized as being the first priority for overseas construction projects. Nevertheless, previous research in design management has been limited to the quality management of the design documents at design stage. Therefore, it is necessary to explore the design management from a comprehensive perspective throughout the project life cycle. In this context, the purpose of this paper is to propose a conceptual framework for integrated design management (IDM). Several different concepts in relation to design management were investigated first in order to identify the major variables of the IDM framework. A comprehensive comparison of construction management methodologies was also analyzed in order to identify key factors of IDM. Finally, an IDM framework was proposed by combining those factors and relevant issues. Based on the proposed framework, a survey was conducted in order to validate the framework as well as to identity important areas for improving competitive capability of Korean construction companies.
