The construction method for Foamed-Concrete has not been important due to following process of construction work. However, according to the code about enhance of energy saving design policy and impact noise, noised isolation has been used in construction site so that the resistance for cracking and capability for insulating of Foamed-Concrete has been required. Therefore, new alternatives are demanded. Optimum mixing design, which can get the improvement of insulation and resistance of crack for Foamed-Concrete adding EVA chip, was derived and also the device, applying to construction site, was invented to equalize quality. This device can measure quantity of all input and placement, and show up the sum of placement and mixing design on a touch screen. This valuable construction method is friendly environment and recycling method because of using EVA chip, by-product of an EVA insole scrap burned or embedded, as a light-weight aggregate.

Recently, the life cycle of products is rapidly shortened and then the W s a l of the used mold applied in development of a product is a difficult things. In this study, we proposed a feasibility of the recycling mold base by analyzing of the existing standard mold base. And we developed a D/B program to promote the mold design capability with CAD. Also, we confirmed the possibility of recycling mold base by testing of a used automobile lamp mold.

This study considers the design of life test sampling inspection plans by attributes for failure rate level qualification at selected confidence level. The lifetime distribution of products is assumed to be exponential. MIL-STD-690C and KS C 6032 standards provide this procedures. But these procedures have some questions to apply in the field. The cost of test and confidence level($1-{\beta}$ risk) are the problem between supplier and user. So, we suggest that the optimal life test sampling inspection plans using expected cost model considering product cost, capability, environmental test cost, etc.

최근 기업 간 기술격차 해소로 사용경험 개선을 위한 제품 디자인 혁신이 기업 경쟁력의 핵심 요소로 인식되고 있으나 국내 중소 중견 기업들의 사용경험 평가 지원을 위한 서비스 시스템 개발은 미흡한 실정이다. 본 연구는 국내 중소 중견 제조기업의 차별적인 제품 설계를 지원하기 위한 사용자 관점의 웹 기반 제품 사용경험 인증 평가 시스템 개발을 목표로 한다. 사용자 중심의 웹기반 시스템의 인터페이스 설계를 위해 사용자의 기능적 요구사항을 파악한 후, 이를 바탕으로 사용자 중심의 워크플로우 분석, 사용자별 태스크 정의, 사용자 니즈를 고려한 기능 정의를 수행 하였으며 최종적으로 주요 메뉴를 구성해 시스템을 설계하였다. 본 연구를 통해 개발된 사용경험 인증 평가 시스템은 사용자별 인터랙션을 고려해 설계되었으며, 특히 평가 효율화 데이터베이스를 통해 일정 수준 이상의 사용경험 평가 프로세스 수행을 지원하고, 지식 데이터베이스를 제공하여 평가 설계 및 제품 개선에 활용할 수 있도록 하였다. 본 연구를 통해 개발된 서비스 플랫폼은 사용경험 평가를 수행하는 컨설팅업체와 사용경험 평가에 어려움을 겪고 있는 중소 중견기업을 연결함으로써 기업의 실질적 사용경험 평가를 지원하고 자체적인 제품 개발 역량 제고에 기여할 수 있을 것으로 기대된다.

Purpose - This research identifies the meaning of the core capability level of Car Master and the reason why its service at the Moment of Truth should be demonstrated through empirical cases. It can be seen that this study differs from existing research because it proposes that the recognized core capability level to achieve customer satisfaction should focus on the mediating effect of Moment of Truth quality. This paper examines the effect of Car Master's recognized core capability level on customer satisfaction by using the variables mentioned above. Moreover, this study uses regression analysis to verify that the mediating effect of Moment of Truth quality on Car Master's capability level achieves customer satisfaction. Research design, data, and methodology - First, we present evidence that could apply to Car Master's recognized core capability level by detailing the relationship between customer satisfaction and a structuring factor for Car Master's core capability level. Our proposed research model observes the relationship between the structuring factor of core capability and customer satisfaction. Second, we had an opportunity to define how the core capability and Moment of Truth quality affect customer satisfaction by performing empirical analysis on the partial mediating effect of Moment of Truth quality at a recognized core capability level and Moment of Truth quality affecting customer satisfaction. Results - First, the results indicate that Car Master's recognized core capability level (product professionalism, marketing skill, and reliability) positively affects customer satisfaction. Second, the results show that an ability to listen and a sense of dedication positively affect customer satisfaction, and are among the Moment of Truth quality factors; but performance capability, which is one of the Moment of Truth quality factors, does not positively affect customer satisfaction. These results clearly differ from prior studies focused on Moment of Truth quality and consumer satisfaction. Third, the results show that Moment of Truth quality has a partial mediating effect in terms of the impact of Car Master's recognized core capability level in achieving consumer satisfaction. Conclusions - This research indicates that the company will be able to expand if they investigate and show an interest in more training and education for Car Master. The study verified that outstanding Car Masters show differentiated performance on customer satisfaction at the Moment of Truth in various instances. Thus, we believe that this is the time for a discussion on systematic and empirically recognized core capability levels and the Moment of Truth quality. The study on Car Master's recognized core capability level offers suitable solutions for Car Masters to respond to customers at the Moment of Truth. Further, this study emphasizes the importance of service as a critical factor having a direct relationship with the company's success and failure and contributing to building trust with the customer. Thus, an investment in continuous education and training for Car Master will help the growth of the business.

As 3-D solid modeling systems have been widely used in product design recently, dedicated design systems for molds of the products have been developed and introduced to mold manufacturers. These mold design systems provide solid modeling capabilites for mechanism to free undercuts. This paper describes an algorithm for slide design capability that has been developed based on a commercial CAD system, Unigraphics. Since the relationship between slide parts were investigated and predefined using parameters in the system, the dimensions and locations of the parts are modifed automatically when a part is modified.

The quality of a precision product, in general, relies on the accuracy and precision of its manufacturing and inspection process. In many cases, the level of precision in the manufacturing and inspection system is also dependent on the positioning capability of tool with respect to the work piece in the process. Recently the positioning accuracy level has reached to the level of submicron and long range of motion is required. For example, for 1 GDARM lithography, 20nm accuracy and 300mm stroke needs. This paper refers to the lithography stage especially to fine stage. In this study, for long stroke and high accuracy, the dual servo system is proposed. For the coarse actuator, LDM (Linear DC Motor) is used and for fine one VCM is used. In this study, we propose the new structure of VCM for the fine actuator. It is 3 axis precision positioning stage for an aligner system. After we perform the optimal design of the stage to obtain the maximum force, which is related to the acceleration of the stage to accomplish throughput of product. And we controlled this fine stage with TDC. So we obtained 50nm resolution. So later more works will be done to obtain better accuracy.
