In order to provide the reliable service and contents to telematics service user, any service server must be tested and verified before launching its service in sufficient. In this paper, we proposed a test framework for telematics server. The proposed framework includes conformance test of server, interoperability test between telematics service server and telematics terminal. The framework proposed the concept and test model for two categories of testing.

For testing machine tools, we used test the work by measure of 3-D object that it was made by the machine tool. By reason of these, we have spent to the cost of measure and have delayed supply to user. In this study, we made a macro-program and a application program in order to test automatic the machine tool. So, if you constitute a ring core and a touch prove in machine tool, you should test the property of machine tool.

디지털 제품의 기능 다양화 및 복잡화에 따라 제품 개발 주기 내 소프트웨어 개발 및 테스트 조직의 업무 중 30∼40% 이상이 소프트웨어 테스트 업무에 집중하고 있다. 급변하는 소비자 요구사양에 대응하기 위해서는 신제품 개발 주기가 짧아지면서 개발 모델 수와 테스트 항목이 지속적으로 증가하고 있기 때문에 소프트웨어 기본 기능 및 UI (User Interface) 검증에 대한 자동화의 필요성이 대두 되었다. 본 논문에서는 휴대폰, DVDP, PDA에 대한 System Integration 작업을 통해 입출력을 정의하고 Black-Box testing을 구현하여 평균 64%이상의 자동화 율과 기본 Test Spec. 대비 80% 이상의 Test coverage를 확보했으며 많은 장단점을 도출할 수 있었다.

This study reviews usability of PC communication softwares with different dialogue types of user interface. Usability test was conducted to evaluate usability of 3 PC communition softwares which are currently utilized in Korea. Learnability was adopted as an index of usability evaluation, so learning time, testing time and scores were measured as dependent variables. It is suggested that softwares with mixing dialogue type(menu, icon, command) which were implemented in window systems environment were not superior to that with command dialogue type.

인터넷의 폭발적인 성장은 웹 어플리케이션의 증가에 영향을 주었다. 웹 관련 기술의 발전과 다양한 비즈니스 요구사항은 웹 어플리케이션을 점점 더 복잡하게 했고, 따라서 품질과 신뢰성이 중요해졌다. 이 논문에서는 웹 사용자 인터페이스의 테스팅 자동화에 대한 방법을 제시한다. HTML페이지의 객체와 자바스크립트의 객체를 매핑시켜, 사용자 입력 폼에 대한 테스트 케이스를 자동으로 생성해서 UI 테스팅을 자동화하는 방법을 보여준다. 또한 제안된 방법으로 테스팅 자동화 사례를 보여준다.

The bedsore prevention cushion serves to prevent the skin on the buttocks of a wheelchair user from being damaged through friction with the wheelchair seat. This is because it absorbs some of the weight applied to the wheelchair seat and allows the weight to be applied evenly to the entire contact surface. For the impact test, which is part of the performance testing of bedsore prevention cushions, a hip model that represents the sitting posture of a wheelchair user is required. In this study, a hip model was manufactured for impact testing of bedsore prevention cushions for wheelchairs. Performance tests for pressure bedsore prevention cushions for wheelchairs include KSP 0236, a Korean standard, and KS P ISO 16840-2, an ISO international standard. The hip model proposed in KS P ISO 16840-2 was more suitable for impact testing of bedsore prevention cushions for wheelchairs. However, the guidelines for making hip models proposed by international standards need to be modified to reflect the advancement of model making technology and use easier methods. We propose a new hip model production method that produces a hip model out of plastic all at once and additionally attaches SS-41 steel plates processed into the shape of the hip to make the mass of the model similar to the human body.

The purpose of this research is to present the major factors which determine dominant design of Smartphone OS and to verify a logical causal relationship with them and user satisfaction. To achieve this goal, OS compatibility, OS enhancement, Installed base, and network effect were presented as determinants of Smartphone OS which serves as the basis for determining dominant design and their logical causal relationship with user satisfaction was empirically analyzed. The results of the research showed that OS compatibility and OS enhancements had a positive effect on the expansion of user base. Of the two factors, OS enhancement showed that it does not only expand the user base but also acts as the cause for the fortification of the network effect. Furthermore, it was shown that OS enhancement had a direct positive effect on user satisfaction. The findings of this research are significant in its academic contribution as well as its potential for practical application by presenting the logical causal relationship in the process of determining OS dominant design an area which was previously untouched by empirical testing.

Smart homes integrated with sensors, actuators, wireless networks and context-aware middleware will soon become part of our daily life. This paper describes a context-aware middleware providing an automatic home service based on a user's preference. The context-aware middle-ware utilizes 6 basic data for learning and predicting the user's preference on the multimedia content : the pulse, the body temperature, the facial expression, the room temperature, the time, and the location. The six data sets construct the context model and are used by the context manager module. The log manager module maintains history information for multimedia content chosen by the user. The user-pattern learning and pre-dicting module based on a neural network predicts the proper home service for the user. The testing results show that the pattern of an in-dividual's preferences can be effectively evaluated and predicted by adopting the proposed context model.
