As customer needs become diversified, there are many efforts to develop creative ideas on the products to satisfy the customer requirement. Also it is very important to classify the customer requirement to the product's quality. According to the previous study, the idea of the products by collecting opinions and brainstorming is mainly studied in new product development. To create the attractive quality for the product, Kano model has commonly been used. However, the brainstorming in the stage of create ideas has the problem of lower linkage between purpose and idea and lower quality of new idea. Therefore, the paper suggests a way to invent more creative ideas by comparing forced connection method to the brainstorming that is applied to the Kano model.

Ubiquitous information technology creates new space connected to electronic and physical space and makes new life pattern come true. Although it is expected that ubiquitous technology will lead significant changes on various life fields, relevant studies on its market needs, customer needs in social and cultural context and its necessity at organizational level have been passively carried out. What is worse, IT technology application scheme in railway field has not fully established since railway field's technology development is mainly focused on hardware compared with road and air traffic. In order to apply ubiquitous technology to railway field, therefore, it is required to identify ubiquitous technology functions which applicable to railway field and to establish ubiquitous rail system implementation scheme for end users. In this paper, we suggested implementation scheme for u-Rail which sorts railway industry by its components in order to implement service centered ubiquitous technology to each railway industry field.

Increased density of racks has resulted in increased use of data center cooling energy and the needs for energy efficient cooling systems has increased. In response to these needs, ASHRAE presented a performance indicator, which is Mechanical Load Component (MLC), for the purpose of evaluating systems at the design stage. However, the MLC metrics presented in the current standard can only be determined for system compliance and compared alternative systems with the system configuration completed. Therefore, there are limitations to considering MLC from the early stages of design. In this study, to extend the scope of application of MLC in the design phase, the design factors of the main equipment comprising the cooling system are classified by the MLC load component and interrelations between design factors were identified.

To meet needs of R&D application reinforcement on geoscience and mineral resources area, we suggest public R&D institute's strategies and system for the application including supplement of technology licensing office (TLO). We review the former studies on technology transfer successfulness criteria and difficulties from the viewpoint of korean small&medium size firms and public R&D researchers, and then benchmark a japanese public R&D institute of industrial science and technology, which was newly integrated and developed with Geological Survey of Japan (GSJ). Application analysis index and the reinforcement strategy hierarchy for R&D project are established on geoscience and mineral resources area, and applied on the prioritized research projects of KIGAM. Empirical investigation was carried out on KIGAM researchers with practical studied analysis on questionnaire and intensive interview. Result of the analysis is identified and compared with the case in Japan. It is shown that KIGAM researchers feel their technology transfer activities are not yet integrated with TLO and commercialized R&D are not cooperated with them. This study proposes industrial cooperation coordinators in the categorized R&D divisions of public R&D institute based on the different R&D characteristics and needs in R&D application strategies.

Recently, depending on the development of smart devices, a variable services have been offered to meet user's convenience. Due to these advance, the needs of users are extremely being diversified and more specific. In that situation, the needs for the N-Screen system has been varied and gradually evolved. An existing N-Screen system that use the way of video streaming upload its multimedia contents to their own cloud server so that might take a long play-reaction time and the number of user is limited by the server's performance. Because of the web based protocol adopted by existing N-Screen system, there are many different problems like high delay, overhead and something caused by simplex data communications. Therefore, to solve the problems above, this study proposes an application based on HTML5. This application supports Video tag and Progressive download via HTML5 so that improves the play-reaction time for multimedia contents. This system can also get rid of the chronic problems such as an access limitation for lots of users as per video streaming encoding. Also, through web sockets, this study proposes a system that has lower delay than the existing system and communicates in full duplex to be able to link dynamically.
