This paper uses the sensibility engineering method to find the model of automobile most appealing to buyers in the $4^{th}$ and $5^{th}$ tier cities of China. Samples of class A & A0 cars were shown to 96 subjects in those cities to investigate their responses in relation to the concepts 'modern' and 'smart'. The result shows that even though men tend to be more sensitive to automobile models in general than women are, both genders showed similar responses to specific models when they were asked to identify a model 'magnificent', 'modern', 'lively', 'smart' or 'cute'. This implies that despite the gender differences in terms of aesthetic sensitivity, both men and women share similar taste in relation to the appearance of cars. Apart from aesthetics, however, men tend to pay a greater attention to the details of design and material used for the cars, while women tend to pay attention to higher priced and better looking cars.

A web-based platform for structural analysis has been developed. The proposed web-based platform is a 2-tier system composed o( client and server sides to reduce the overburden on the server side. Smart Client is applied for the client side to improve the handling speed and UI. For the server side, MSSQL is applied to deal with database and used as a storage for the web. XML WebService is adpoted for the networking between the client and the server. To examine the efficiency of the developed web-based platform a sample study is carried out with a nonlinear earthquake analysis on a SDOF system.

1990년대 초반에 등장한 자바 언어는 빠른 속도로 프로그래머들 사이에 보급되었으며 인터넷의 등장과 더불어 이는 더욱 가속화되었다. 또한 무선 플랫폼 등과 같은 새로운 컴퓨팅 환경에 빠르게 대처함으로써 자바 언어의 끝을 예측하기는 쉽지 않은 상태이다. 초기 자바 어플리케이션들은 단일 티어(single-tier)로 개발되었으며 환경의 변화로 인해 이런 어플리케이션들을 네트워크로 연결할 필요성이 대두되고 있다. 자바 언어는 분산 컴퓨팅 환경의 솔루션으로 Enterprise JavaBean(EJB)［1］을 제시하고 있다. 본 논문에서는 기존에 개발된 자바 어플리케이션을 EJB로 래핑하기 위한 기법들을 제공한다. 핵심 비즈니스 로직을 가진 클래스들을 수작업을 통해 EJB로 변환할 수도 있지만 본 논문에서는 반자동화된 방법을 통해 변환 상의 효율을 증대시키고 변환 과정에서 발생할 수 있는 오류를 최소화하고자 한다. EJB 래핑 기법은 세션 빈(session bean)［1］래핑과 엔터티 빈(entity bean)［1］래핑으로 구성된다. 세션 빈 래핑은 자바 어플리케이션을 구성하는 클래스 가운데 질의문(query)을 가지지 않는 자바 클래스들을 래핑한다. 엔터티 빈은 질의문을 포함하는 자바 클래스를 래핑한다. EJB 래핑을 위해 리플렉션(reflection)［2］과 위임 (delegation) 장치를 사용한다.

This cross-level study of 77 samples from Korean 1st-tier suppliers participating in knowledge-sharing networks examined the impact of partnering(joint establishment of goal and joint problem solving system) on supplier relationship outcomes(competativeness improvement and innovative idea suggestion). The findings showed that joint establishment of goal and joint problem solving system were positively related to both supplier's competativeness improvement and its innovative idea suggestion. Whereas, joint problem solving system did account for a significant variance only in innovative idea suggestion. The findings, further, demonstrated that mutual trust moderated the relationship between joint problem solving system and supplier relationship outcomes. Implications for theory and practice are suggested.

인터넷 보급률이 증가함에 따라 동시 접속자 수가 크게 증가한 요즘 기존에 소규모 시스템 및 소수의 사용자에게 적합한 클라이언트와 서버 방식인 2-티어 환경에서의 시스템은 성능저하의 요인이 되었고 이는 대규모 프로젝트 수행시 좀더 높은 성능으로 처리하게 되었다. 본 논문에서는 대규모 프로젝트의 최적의 성능 및 유지보수 편의성을 제공하기 위해 닷넷 리모팅 서비스와 스마트 클라이언트를 기반으로 한 3-티어 환경에서의 학사시스템 아키텍쳐를 설계하였다.

A web-based platform for nonlinear earthquake analysis on SDOF systems has been developed in the research. The proposed web-based platform is a 2-tier system composed of client and server sides. Smart Client is applied for the client side to improve the handling speed and UI compatible to the stand alone systems. For the server side, MSSQL is used as a storage for the web. XML WebService is adpoted for the networking between client and server. To examine the efficiency of the developed web-based platform, a trial study on a SDOF nonlinear structural system under earthquake excitation has been carried out.

흔히들 산업계에서는 일등만이 살아남을 수 있으니 반드시 일등이 돼야 한다고 주장한다. 그러나 항상 '이 말이 사실일까?'라고 의문을 제기해 보면 반드시 그렇지 않다는 것이 결론이다. 물론 일등을 하면 시장을 선도하면서 생기는 장점들, 이를테면 큰 시장 점유율, 높은 이익률, 시장의 방향을 결정하는 것 등 여러 가지가 있다. 그러나 이런 장점들을 누리지는 못하더라도 2등과 3등, 심지어는 훨씬 낮은 등위에서도 나름대로 선방하는 많은 기업들이 존재하는 것이 현실이다. 자동차 시장에서는 프랑스의 푸조, 카메라 시장에서는 일본의 올림푸스, 휴대폰에서는 대만의 HTC 등은 업계 1위는 아니지만 나름대로 특화된 영역에서 존재감을 보이고 있는 기업들이다. 이런 사례들은 산업분야에서 뿐만 아니고 표준이나 특허 분야에서도 찾아볼 수 있다. 따라서 치열한 표준전쟁에서 나름대로 입지를 다지고 있는 Second Tier Player 들의 생존 전략을 분석해 보는 것도 의미 있는 작업이라고 보여진다.

This essay traverses the ontological space of IS research and identifies various misconceptions, biases, and conceptual peculiarities that inhabit the research. Three aspects of the IS ontology are examined: the conceptualization of the IT construct, demarcation of phenomena for investigation, and conceptual binding of the IT construct to other constructs. Various ontological issues are discussed including the transparency of the IT construct, the objectification of IT, and the causal primacy assigned to IT. The ontological purviews are further explored and their inadequacies are traced in the structurational explication of IS phenomena. At the end, some epistemological implications of the IS ontology are discussed and a two-tier theory structure is proposed for IS research.

In this paper, we analyze the M-WiMAX UL capacity limits under 2-Tier cell layout, considering the effects of random user position, path loss models, fading channel and adjacent channel interference from WCDMA system. In order to make the analysis approximate to the practical system capacity, we propose a MCS-based capacity analysis method considering the effects of PER requirement and the utilized MCS levels in M-WiMAX system. The proposed MCS-based method is validated through a system-level Monte Carlo simulation. Furthermore, a comparison between the conventional Shannon method and the proposed MCS-based method is presented and the optimum cell radius is suggested.
