This study presents the alternative evaluation technique for the high-rise building structural system. The alternative evaluation of the structural system is performed in three steps, that is, preliminary evaluation, main evaluation and detailed evaluation. The evaluation categories are composed of structural performance, economic feasibility and term of work. Each categories are composed of detailed items to evaluate of its own. In preliminary evaluation, qualitative evaluation based on experimental knowledge is performed. In main and detailed evaluations, quantitative evaluations based on numeric data are performed. The weighted-sum method is applied to integrate the evaluated results of each items and its importance. The applicability of the proposed method was verified by applying it to the practical buildings and simulate the procedures.

In the knowledge society, alternative leadership induces voluntary participation by motivating the members through horizontal, emotional approach and responsibility. There is little theoretical discussion about theoretical research on alternative leadership and its applicability in university libraries. In this study, we will discuss the theoretical review of alternative leadership, the change of knowledge management paradigm in university library, the role of manager and librarian, and alternative leadership application. Through this, I would like to suggest the development direction for strengthening the leadership of the librarians who will lead the university library.

Container terminals keenly compete with one another because of the continuous increase of container flows and the appearance of large-sized vessels. Major cargo handling equipment manufacturers are interested in the development of new conceptual equipment to greatly increase its productivity. In this study, a two-phase procedure is suggested for selecting the optimal development alternatives, when various development alternatives for container cranes are given. The first phase removes the alternatives that violate essential requirements and the second phase selects final alternatives by the evaluation of experts and the linear assignment method. Finally, a case applying the procedure is provided.

In this paper, essential technological elements for applying GIS and GPS based AVL system to the logistics information area were reviewed. Then system alternatives were evaluated using Life-Cycle Cost Analysis. In the basic scenario, the roadside infrastructure alternative is turned out to be more efficient that the other. The sensitivity analysis shows that under the different conditions and unit costs, the wireless communication alternative can be more economical. Mixed approach based on characteristics of transportation facilities should be considered.

The genre of digital games is not a fixed and invariable system, but a generative system of revisions and changes. The purpose of this study is to define a concept of alternative genre for digital games. The alternative genre of digital games should be presented in combinations of various genre elements and reflected the genre awareness of the user. In this context, user tags of the game transform the classical genre concept into a family resemblance based categorization and establish a user-driven bottom-up genre system. User tags as the form of alternative genre can spread the 'small' genre through multiplicity of genre elements and strengthen the communicative function of the genre.

At the "Dissemination Stage", the newly configured technical design is compared with other alternatives to come up with the most desirable selection. The assessment conducted at this stage is not a simple procedure. It goes through the complex evaluation process in which various elements including economic effects and technical characteristics are considered. The reason for taking such a complex procedure is that the assessment, selection and application of the desirable technical alternative is critical for the company's competitive edge in every field of industrial sectors, thus influencing its survival and continuous growth. This study reviews the MAUT method for assessing technical alternatives of the thermal supply system design. And, to show the practical validity of the MAUT method, it is applied to the evaluation of thermal supply system alternatives in the field of energy supply system technology.

본 연구는 특정 조직의 정보 인프라 개발을 위한 전략적 계획을 수립하기 위해 의 사결정 지원 도구로서 다수 목표 의사결정 모형 (Multiple Objective Decision-Making Model : MODEM), 구체적으로는 목표 계획법(Goal Programming : GP)의 응용을 제시하고 있다. 연구대상 조직은 3년 동안의 정보 인프라 개발 프로젝트를 추진하고 있다. 이러한 특 별 프로젝트는 조직 전체에 궁극적인 통합 정보 기술 서비스를 제공하기 위하여 최고 의사 결정자의 전략적 계획 측면에서 추진되고 있다. 본 연구는 총 8개의 목표가 수립되었고 현 조직 환경하에서 이들 목포들에 대한 우선 순위가 설정되었다. Micro Manager가 본 연구 모형의 실행을 위하여 활용되었고 분석결과 6개의 정보 인프라 프로젝트 중 첫 5개가 실행 되기 위하여 선택되어 졌으며 4개의 네트? 대안 중에서 첫 번째 대안이 최적 대안으로 선 택되었다. 초기 설정 목표들에 대한 우선 순위를 변경시킴으로써 연구 모형의 가변성을 검 토하기 위해 민감도 분석이 실행되었다. 변경된 목표와 우선 순위하에서는 6개의 정보 인프 라 프로젝트 중 3개만이 실행을 위하여 선택되었고 네트? 대안은 첫 번째 대안이 역시 최 적 대안으로 선택되었다. 본 연구 모형은 다수의 서로 상층하는 목표를 가지는 조직 및 이 와 유사한 경영환경에 직면해 있는 전략적 의사결정 수립에 효과적인 방안을 제시할 것이다.

전자 카탈로그 상에서의 상품 검색은 카탈로그에 명시되어 있는 상품을 찾는 표준상품검색과 소비자가 원하는 상품을 맞춤 하는 맞춤상품검색으로 분류할 수 있다. 현재의 대부분의 상품 검색은 표준상품검색에 의존하고 있다. 특히 기업간 구성요소기반(Component-based) 상품의 경우 표준상품검색만으로는 구매자의 다양한 요구에 응하기가 어렵다. 따라서 웹 상의 전자 카탈로그에서의 동적인 맞춤검색에 대한 요구가 증가하고 있다. 본 연구에서는 구성기반 상품에 대해서 표준상품검색만으로는 구매자가 원하는 상품의 검색가능성(Feasibility)과 검색된 대안들이 조정(Adjust) 프로세스 과정을 거쳐 최적해 도달 가능성(Admissibility)이 보장되지 않음을 보이고, 이에 대한 효과적인 방법론으로 검색가능성과 최적해 도달 가능성을 지원하는Template-based Reasoning 방법론을 제안 한다. Template-based Reasoning은 구매자의 요구사항에 따른 대안탐색 부분과 선택된 대안에 대한 조정과정의 두 단계로 이루어진다. 구매자의 주요 선호도(MUST Preference)에 근거하여 대안들을 탐색하고, 탐색 된 대안들 간의 우선순위를 결정한다. 조정 단계에서는 옵션(Options)의 확장을 통해 구매자의 맞춤사양에 따른 상품을 제안하고, 제약 및 규칙기반 추론(Constraint and Rule Satisfaction Approach)을 이용하여 옵션(Options)들 간의 제약조건에 따른 호환성(Compatibility)을 조사하고, 적정가격의 상품을 제안한다. 본 방법론은 Template을 사용하여 기본적으로 구매자가 원하는 상품을 검색하기 위한 검색노력을 줄이고, 검색된 대안들로부터 구매자와 시스템이 웹상에서 서로 상호작용(interactivity) 하여 해를 찾고, 제약조건과 규칙들에 의해 적합한 해를 찾아가는 방법을 제시한다. 본 논문은 구성기반 예로서 컴퓨터 부품조립을 사용해서 Template-based reasoning 예를 보인다 본 방법론은 검색노력을 줄이고, 검색에 있어 Feasibility와 Admissibility를 보장한다.

In this research, we seek to identify an effective operation management strategy of telecommunication systems. In order to develop operation management strategies, we implement a quantitative techno-economic analysis. We evaluate related issues and factors, and apply the developed method to PSTN switching systems. In the proposed techno-economic modeling, we apply a well-known factor analysis technique-analytic hierarchy process-to evaluate PSTN operation management strategies. Then, we implement a decision analysis methodology to evaluate the cost of proposed strategies. We evaluate the proposed methodology by using available real data of the PSTN system. The primary impact of this research will be realized in helping PSTN operator select the best operation management strategy of PSTN system.

Container terminals compete with other ones because of the continuous increase of container flows and the appearance of large-sized vessels. Major port equipment manufacturers are interested in the development of new conceptual equipment ot greatly increase the productivity. In this study, a two-phase procedure is suggested for selecting the optimal development alternatives, when there are various development alternatives for container cranes, typical equipment in ports. The first phase removes the alternatives that violate essential requirements and the second phase selects find alternatives by using AHP (Analytic Hierarchy Process). Finally and example applying the procedure is provided.
