Purpose - The existing ICT based services for tourism are limited to supporting to service only partial functions among overall tourism processes which consists of tourism planning process, tourism activities and tourism experience sharing. The ICT based service system that supports tourism services necessary in the overall tourism process is known not to be yet introduced in domestic tourism area. It is necessary to conceptualize and design schematically the ICT based tourism service system for supporting the overall tourism process. In this paper, we propose the concept and skeleton functions of the integrated tourism platform, which would support services that tourists and tourism suppliers might require in smart tourism environment. Research, design, data, and methodology – The concept and skeleton functions of the integrated tourism platform might be derived in a qualitative research method. We proposed a concept of tourism life cycle proposed first. We investigated and analyzed the service functions of the existing ICT based tourism service systems that support each step in the tourism life cycle so that the concept and skeleton functions of the integrated tourism platform were derived with results that experts in tourism and ICT areas discussed in brainstorming ways. Results - We proposed the concept of tourism life cycle needed to derive the functions of the integrated tourism platform. The tourism life cycle contains six phases, which consists of planning, research, booking, travel, reviews and inspiration phases. The tourism life cycle is to departmentalize overall tourism process. The integrated tourism platform consists of data platform and service platform. The data platform is a kind of large scale database with integrating various types of data. The various data would be collected by web crawlers or inputted manually by tourism providers. The Ontology and Mash-up technologies should be applied to integrate the various types of data effectively to make data with good quality. Conclusions - The integrated tourism platform could support the overall tourism process in tourism life cycle. It does not only provide personalized tourism information and products for tourists, but also, provide opportunities with deriving creative business items for venture business mans. The service platform would also ICT based service system to support Sharing economy in the Fourth Industrial Revolution.

압연판재의 결정립 미세화를 위해 새롭게 도입된 극저온 강압연법을 극저온 압연법, 상온 강압연법과 비교 분석하였다. EBSD를 이용하여 결정립 구조를 분석하였으며, 결정립 크기를 측정하였다. 극저온 압연법과 상온 강압연법은 각각 39%와 87%의 결정립 크기 감소효과를 보였으며, 극저온 강압연법은 상온 강압연법과 비슷한 결정립 감소효과를 갖고 있었다. 따라서 강압연법이 극저온 압연법보다 결정립 미세화에 훨씬 더 효과적임을 알 수 있었다. The effect of cryogenic heavy rolling method on grain refinement has been studied and compared with those obtained by previous methods of cryogenic rolling and heavy rolling developed separately. Both grain structure and grain size were analyzed using electron back scattered diffraction (EBSD), which can distinguish grains each other by means of crystallographic misorientations between them. The cryogenic rolling and heavy rolling exhibit reduction in grain size of 39% and 87%, respectively, and the cryogenic heavy rolling shows reduced grain size similar to that observed in the heavy rolling. The heavy rolling was proved more effective in grain size refinement than the cryogenic rolling.

This paper deals with the effects of the surfactant and preplate process (sensitization and activation) on electroless copper plating on carbon nano-fiber (CNF). Ultrasonic irradiation was applied both during dispersion of CNF and during electroless plating containing preplate process. The dispersion of CNF and flatness of the plated copper film were discussed based on the changes in surfactant concentration and preplate process time. It was clearly shown that high concentration of surfactant and long time of preplate process could promote the agglomeration of CNF and uneven copper plating on CNF.
