감성정보를 디자인 활동에 필요한 정보로 활용하기 위해서는 전체 디자인 프로세스에서 사용자를 최초 컨셉 단계에서부터 참여시켜 관찰 및 평가에 적극 동참케 하는 사용자 참여 디자인이 매우 효과적이다. 이러한 감성 정보 수집 및 평가를 통한 상용자 인터페이스 디자인 개발 프로세스를 MP3 CDP를 대상으로 적용하여 연구를 진행하였다. 최근의 MP3CD Player들은 일반 음악 CD들이 10여곡에서 많게는 20여곡 정도의 분량을 가지고 있는 것에 비해 그 분량이 최고 100여곡 이상에 이르고 있다. 그럼에도 불구하고 MP3CD Player들은 기존의 일반 음악 CD Player의 UI를 소극적으로 수정, 변경하여 사용하고 있는 상황이다. 본 연구는 자체적인 곡 분류방법을 제시하고 있는 ‘H’사의 MP3CD Player를 선정하고 이를 기준으로 초기 디자인에 사용자를 참여시켜 사용자 감성 정보 및 요소들을 효과적으로 평가하여 사용자 중심 디자인을 극대화 시키는 방법을 모색하였다. 제품의 최초 기능 분석시에는 카드인덱스(Card Index)방식을 이용하여 기능을 그룹핑하고 인터페이스를 개선하였으며 이를 토대로 프로토타입을 완성하였다. 이를 사용자가 직접 조작하는 방식을 관찰 분석하여 평가 결과를 토대로 UI 디자인가이드라인을 제시하였다.

최근 세계적으로 게임 산업은 문화콘텐츠 산업의 핵심으로 인정받고 있으며 우리 정부도 21세기 국가성장 동력의 핵심영역으로서 게임을 지목하고 있다. 그 중 2002년 아케이드 게임을 제치고 처음으로 1위로 등극한 온라인게임은 2003년에는 플랫폼 생산매출 $50\%$를 차지하며 국내 게임시장을 견인하고 있다. 그러나 게임 산업의 인기와 온라인게임의 확산에 비해 대부분의 게임제작업체들은 짧은 기간의 간단한 베타테스트에 의존하고 있어 콘텐츠의 품질평가에 대한 인식 부족과 만족스러운 테스트 결과를 얻기에는 부족함이 많다. 이러한 문제점을 해결하기 위해서는 온라인 콘텐츠의 특성을 반영한 체계적인 품질모델 및 모델에 기반을 둔 품질평가 프로세스 그리고 각 품질특성을 시험하기 위한 시험기법들이 필요하다. 본 논문에서는 ISO/IEC 9126 및 14598 기반의 온라인 게임콘텐츠 품질평가 모델 선정과 품질평가 프로세스를 제시하고자 한다.

The procurement of public construction, which has been selected mainly on the basis of the work experience of a department of public agencies that award construction contracts or those in charge of ordering, has not been executed through an objective selection process considering the construction types or characteristics. Thus, as a preliminary study on developing a model for the selection of contract methods, this study intends to analyze and present the key factors affecting the selection of procurement methods in public construction. Through a literature review on the existing methods, foundational factors were first presented, based on the analysis of these factors, the final influence factors were proposed. As a result, 6 factors contractor's characteristics, the environment of the construction market, relevant organization, the characteristics of a project, costs, and responsibility factors were determined, and 14 sub-factors were selected. The factors presented in this study will be used as base data for developing a decision making support model for the selection of contract methods in public construction.

Site selection processes for high-level radioactive waste disposal facilities in different countries differ in terms of local geology and degree of public engagement. There seem to be three alternative processes for site selection: (1) selection with community consent after government choice; (2) selection with continuous community engagement after exclusion of unsuitable areas based on existing survey data; or (3) site selection where communities have expressed a willingness to participate. The Yucca Mountain site in Nevada, USA, was selected as the final disposal site by process (1) through six stages, but its development was suspended owing to opposition from the local governor and environmental groups. In Sweden, Switzerland, and Germany, process (2) is used and sites are selected through three stages. Sweden and Switzerland have completed site selection, and Germany is currently engaged in the process. The UK adopted process (3) with six stages, although the process has been suspended owing to poor community participation. In Korea, temporary storage facilities for spent nuclear fuel will reach saturation from 2030, so site selection must be promoted through various laws and systems, with continuous communication with local communities based on transparent and scientifically undertaken procedures.

Six sigma is an innovative management movement which provides improved business process by adapting the paradigm and the trend of market and customers. Suitable selection of six sigma project could highly reduce the costs, improve the quality, and enhance the customer satisfaction. There are existing studies on the selection of Six Sigma projects, but few studies have been conducted to select the correct project under an incomplete information environment. The purpose of this study is to propose the application of integrated MCDM techniques for correct project selection under incomplete information. The project selection process of six sigma involves four steps as follows: 1) determination of project selection criteria 2) calculation of relative importance of team member's competencies 3) assessment with project preference scale 4) finalization of ranking the projects. This study proposes the combination methods by applying group fuzzy Analytical Hierarchy Process (AHP), an easy defuzzified number of Trapezoidal Fuzzy Number (TrFN) and Grey Relational Analysis (GRA). Both of the weight of project selection criteria and the relative importance of team member's competencies can be evaluated by group fuzzy AHP. Project preferences are assessed by easy defuzzified scale of TrFN in case of incomplete information.)

This study is planned with the aim of developing a systematic construction process based on the scientific and engineering theory of the water-sealing grouting construction applied to the tunnel excavation process during the construction of the downtown underground traffic network, so that the construction quality of the relatively backward domestic tunnel water-sealing grouting construction is improved and continuously maintained no matter who constructs it. The main contents of the improved tunnel water-sealing grouting can be largely examined in the classification of tunnel water-sealing grouting application and the definition of grouting materials, the correlation analysis of groundwater pressure conditions with groundwater inflow, the study of the characteristic factors of bedrock, and the element technologies and injection management techniques required for grouting construction. Looking at the trends in global research, research in the field of theoretical-based science and engineering grouting is actively progressing in Nordic countries (Sweden, Finland, Norway, etc.), Japan, Germany, and the United States. Therefore, in this study, the algorithm is established through theoretical analysis of the elements of tunnel water-sealing grouting construction techniques to provide an integrated solution including a construction process that can effectively construct tunnel water-sealing grouting construction.
