Due to the rapid growth of Internet, means of communication with customers in a traditional customer support environment such as telephone calls are being replaced by mainly e-mail in a Web-based customer support system. Although such a Web-based support is efficient and promises potential benefits for firms, including reduced transaction costs, reduced time, and high quality of support, there are some difficulties associated with responding to many types of customer's inbound e-mails appropriately. As many types of e-mail are received, considerable attention is being paid to methods for increasing the efficiency of managing and responding e-mails. This research proposes an intelligent system for managing customer's inbound e-mails in organizations by applying case based reasoning technique for responding to various customers' inbound e-mails more effectively. In this approach, a case is represented as a frame-typed data structure corresponding to an inbound e-mail, keywords, and its reply e-mail. In the retrieval procedure, keywords and affinity set is developed to index a case, and then the case is represented as a vector, a case vector. Also, cosines value is calculated to measure the similarity between a new inbound e-mail and the cases in the case base. In the adaptation procedure, we provide several adaptation strategies to adapt and modify the retrieved case. The strategies guide to make an outbound e-mail using product databases, databases for customer support, etc. Additionally, the Web-based system architecture is proposed to implement our methodology. The proposed methodology and system will be helpful for developing more efficient Web-based customer support.

The purpose of this study is to understand and compare the characteristics of the content organization system of three Environment textbooks currently used, and to examine its connectivity with the teaching & teaming methods included in the Environment subject part of the 7th Korean National Curriculum. For the analysis three Environment textbooks for middle school and their teacher's guide books by three companies. published(A, B, and C) The result of the taxonomic analysis showed that three Environment books had different steps to get to the lesson class unit in the way that A of six steps, B of five steps and C of seven steps. The amount of main text was different In the domains of'Human and Environment','Environmental Problems and its Counter-plan'and'Environmental Conservation'of three textbooks each. All of three textbooks had the biggest percentage in sub-domains of'Living Environment to Keep'and'Global Environmental Problem'in 'Environmental Problems and its Counter-plan'domain. Considering teaching & loaming methods all of three textbooks contained many activities as 55 in A, 66 in H and 91 in C. Among 9 teaching 8E teaming methods and others listed in the Environment subject part of the 7th Korean National Curriculum, the investigation method is most frequently used in all of three textbooks. The drama, the paly and the case study were used rarely as teaching & teaming methods in activities In the consideration of the content amount regarding academic fields, it was revealed that three textbooks overemphasized the aspect of natural sciences comparing the aspect of human & social sciences aspect as a whole. Generally the appendix section of all three textbooks were well organized to support the teaching and teaming activities in main text.

The purpose of this study is to understand the characteristics and the differences regarding the teaching & learning objectives of Environment textbooks for middle school students with the consideration of the 7th Korean National Curriculum. For this the teaching & teaming objectives of three Environment textbooks currently used categorized according to the domain frame of environmental education in the Report of UNESCO(1980). three Environment textbooks and their teacher's guide books are those printed by three companies(A, B, and C) and Joongahng co.. The five objective categories recommended by UNESCO are awareness, knowledge, attitude, skills and participation and six types of skills by National Curriculum Council of England are communication skills, numeracy skills, study skills, problem-solving skills, personal and social skills and information technology skills. It is showed that'Human and Environment'domain is emphasized roughly in the awareness and the knowledge section without any statement of the participation section, 'Environmental Problems and its Counter-plan'domain in the knowledge and the skills section, 'Environmental Conservation'domain in the skills and the participation section of objectives. It is revealed that the skills section of the teaching 8t learning objectives is mainly involved in 'Environmental Problems and its Counter-plan'domain and'Environmental Conservation' domain. According to the result of the analysis of the connectivity between the Environment Curriculum of the 7th Korean National Curriculum and the Environment textbooks regarding objectives stated in the sub-domain level, it says those are generally appropriate ones. But some objectives are emphasized weakly or not at all in several sub-domains such as'The living environment to keep','The environmental problems of the earth','Making environment pleasant'. It is proposed that the efforts to state objectives in the Environment textbooks evenly are needed to be paid (or the well-balanced teaching & teaming of the Environment subject.

FRP(섬유강화 복합재료)를 교량의 바닥판으로 설계하기 위하여 위상최적화와 형상최적화 기법을 사용하여 이론적 최적단면을 제안하였다. 먼저 위상최적화를 통하여 바닥판의 최적 단면모양을 찾아 내었다. 그 결과, 단순보에서 중앙 집중하중의 경우 가장 이상적인 구조는 트러스 형태의 골조구조임을 알 수 있었다. 또한 수평부재와 경사부재가 만나는 절점에서 보강재를 볼 수 있었고, 이는 기존 상업용 FRP바닥판에 적용되지 않았기 때문에 새로운 설계변수로 사용하였다. 두 번째로 유전자 알고리즘을 이용한 형상최적화를 통하여 위상최적화 결과의 최적 규격을 찾고자 하였다. 기존 상용제품들과 비교를 위하여 바닥판의 높이를 제한하여 최적화를 수행하였다. 본 논문에서 제안한 바닥판의 성능을 검토하기 위해 유한요소해석을 수행하였다. 사용성 및 안전성을 검토한 결과, 기존 연구에서 제안한 설계 기준안을 만족하는 것을 확인하였다.

모바일 환경의 발달로 인하여 온라인 컴퓨터에서만 가능해 보였던 RPG 장르가 이제는 모바일에서도 가능한 환경이 되었다. 하지만 모바일은 온라인 컴퓨터와 하드웨어 환경이 다른 만큼 RPG의 기본 요소와 틀은 유지하되 모바일 환경에 맞게 변형되거나 이식되었다. 전투밸런스에 대한 평가 모델 연구가 존재하지만 MMORPG를 중심으로 한 평가모델로 모바일 RPG에 적용하기에는 적합하지 않다. 그 이유는 기존의 모델에서는 사용자의 컨트롤 능력이나 다른 사용자들, 게임 오브젝트의 변수들이 많이 존재하기 때문에 가장 기본적인 요소들만을 사용할 수 밖에 없었다. 그래서 기존 모델에서는 전투밸런스에 대한 가이드 라인만 제시하는 정도였다. 이 논문에서는 기존에 평가 모델에서 적용하기 어려웠던 보너스 효과 (버프와 너프, 그리고 패시브 능력)을 포함시켜 최근 모바일 RPG 트랜드에도 적용이 가능한 평가모델을 만들고자 하였다. 그 결과 기존의 모델에서는 측정하지 않았던 항목도 계산이 가능하였다.
