Recently, a new theoretical and methodological approach for computational science is becoming more and more popular for analyzing and solving scientific problems in various scientific disciplines such as Computational fluid dynamics, Chemistry, Physics, Structural Dynamics, Computational Design and applied research. Computational science is a field of study concerned with constructing mathematical models and quantitative analysis techniques and using large computing resources to solve the problems which are difficult to approach in a physical experimentally. In this paper, we present R&D of EDISON open integration platform that allows anyone like professors, researchers, industrial workers, students etc to upload their advanced research result such as simulation SW to use and share based on the cyber infrastructure of supercomputer and network. EDISON platform, which consists of 3 tiers (EDISON application framework, EDISON middleware, and EDISON infra resources) provides Web portal for education and research in 5 areas (CFD, Chemistry, Physics, Structural Dynamics, Computational Design) and user service.

Despite consumers' increasing awareness and interests in innovative wearable devices, the sales growth has been stagnant. To analyze this phenomenon, we investigate consumer preferences for various innovative features embedded in wearable devices. Conducting conjoint analysis on smartwatches, we empirically show that the curse of innovation can occur when the consumer's expected utility from the smartwatch falls short of his/her psychological cost associated with behavior change from smartwatch usage. Therefore, our findings provide managerial implications on the R&D strategy for new technologies and more importantly on the marketing strategy easing consumers' resistance to highly innovative products.

The journal is a important resource of the scholarly communication and it is a kind of the R&D indicator. But the journal subscription cost is rising annually so it has the limits to the journal subscription fee of libraries. This paper analyses the usage of Document Delivery Service(DDS) according to the journal subscription overlapping with NDSL members. In order to select journals for analysis, this paper selects journals of the subscription overlapping top 20% and low 20% and finds out the relationship between the overlapping subscription and usages of DDS.

This study aims to establish the direction of development of Korean cinematography technology in the era of the 4th Industrial Revolution and present future development plan. First, in order to diagnose the current status, supporting policies of various countries and film technology research trends were analyzed. Each country is expanding the support for film technology including tax credits. Through the analysis of patents and research papers, recent issues have shown that Virtual Reality, HMD, Artificial Intelligence, and Big Data are applied to film technology. Next, the survey results of Korean film technology level for filmmakers were 70% for production, 47.5% for distribution, and 60.3% for screening comparing to the level of the leading country. The gap was caused by the lack of funds for research and development and insufficient government support policies. In addition, interviews with film makers revealed the need to support filmmaking that combines technologies such as localized film technology, artificial intelligence, and deep learning. Finally, it is suggested that technology sharing platform should be developed in the future through the discussions of technology, science and academic experts', and technology development should be carried out in the field. As a result, film technology R&D should be promoted in order to develop technologies specific to movies. Advanced technology foundation for the growth of film technology should be developed to systematically equip the infrastructures such as education and human resources. In addition, technology development that links standardization should be carried out. In this study, we propose the development of Korean film technology to prepare for the 4th Industrial Revolution, and it is expected that the 2022 film technology power nation will be realized.

The current development of digital platform-based online retail business leads to the rapid growth of freight demand and service innovation. With the demand for converged logistics technologies, our government supports R&D projects to innovate the logistics service. The digital platforms are developed based on their own standard process and data formats. It may cause interoperability and connectivity-related problems. In this research, the standard data flow to connect the data among systems is defined based on the standard process. Especially, data for connectivity is categorized into three groups, common data, connected data, and management data. It may be possible to enhance the applicability to the practical logistics business.

In this study, for the integrated information management of underground pipelines, each information management server software must have it's inter-operability. So Many kinds of smart-city integrated platform softwares were surveyed and the best platform software was selected. The interface software modules developed in this study was installed at the test system. Through this test system, when a sub system transfers an event message to the upper integrated server system, the inter-operability test between the upper system and a sub operating system was performed and its operability was resolved.

Technology foresight is the process which investigate long term science, technology, economic and social effects to derive strategic R&D and future promising technologies. This study shows that new systematic framework based on technology classifications of space and action in human society, future six senses was employed as a new research method for effective process of future technology foresight. In addition, to increase the acceptance, forecasting, and uniqueness of new technology, we derived major issues of future society and demand-base products and services through the new process of ICT future mega trend analysis, the findings and selections of future technology, and future scenario based on human six senses.

In this paper, we review relevant technologies of MR (Mixed Reality) and show important components of perspective that can overcome technical limitations of the current MR. An MR technology combines real and virtual objects in a real environment, and runs interactive in real time, and is regarded as an emerging technology in a large part of the future of IT (Information Technology). We've grouped the major obstacles limiting the wider use of MR technologies into three themes: technological limitations (i,e., tracking, rendering, authoring, and registration), user interface limitations(i.e. UI metaphor for MR interaction), and social acceptance Issues.

본 연구는 국내 창업초기투자생태계의 현황을 진단하고 향후 진화의 방향과제를 도출하는 것이 목적이다. 2013년 정부의 투자중심 창업지원 생태계 구축정책에 힘입어 국내 창업초기 투자생태계는 보다 세분화되고 활성화 되고 있다. 종전의 엔젤투자와 VC 투자자로 양분되었던 벤처투자시장에, 특히 창업초기단계 개인엔젤투자조합, 전문엔젤, TIPS, 엑셀러레이터와 창업초기 전용VC 펀드인 인큐베이팅펀드와 청년창업전용투자펀드등에서 최근 마이크로VC펀드에 이르기까지 다양한 창업초기 VC 펀드가 창출되며 다양한 그룹의 투자자들이 생성 진화중이다. 이렇게 창업초기 다양한 투자자그룹이 생성되고 성장하고 있는 이면에는 정부의 매칭투자와 투자연계 R&D 자금이 큰 역할을 하고 있어 투자자들에게는 창업기업에게 Valuation과 투자 위험 관리에 큰 도움을 주고, 창업기업에게는 과도한 지분의 희석 없이 투자자금이 가진 장점의 혜택을 극대화하고 있다. 그러나 본 연구의 국내창업초기 투자생태계 진단결과, 국내 창업투자생태계는 다양한 투자자그룹이 생성되고 성장하고 있지만 서로 다른 투자자 그룹 간 공동투자나 후속투자 연계 등의 협업적 활동 및 회수네트워크 연계 등 활동은 아직 미흡하다. 또한 투자분야 자체가 모바일 및 인터넷서비스 분야에 집중되고 있어, 상대적으로 긴 시간의 보육과 성장검증기간 및 규모 있는 투자를 필요로하는 제조분야는 비중이 약한 편이어서 투자 대상 사업 분야의 다변화 필요하다. 뿐만 아니라 국내 창업초기투자생태계는 창업의 글로벌 사업성과를 내기 위한 글로벌 투자자들과의 연계구조는 미흡한 상황이어 이를 촉진할 방안이 요구된다고 할 수 있다.

본 연구는 일상에서 길을 찾는 데 어려움을 겪은 보행자나 초행길을 낯선 여행자들을 대상으로, 스마트폰과 더불어 사람들이 많이 지니고 다니는 가방을 가지고 적용하였다. 스마트폰의 LBS, 블루투스 기능과 가방에 부착된 진동 인터페이스가 연결되어 실시간 경로 안내를 받을 수 있는 제품이다. 부가적인 기능으로는 앱 상에 회원관리 기능이 있어 개인의 이용 기록에 관한 데이터가 DB에 저장되며 DBMS를 통한 데이터 분석으로 사용자에게 맞춤화된 서비스를 제공해 줄 수 있다. 또한 여러 사용자들이 이용한 플랫폼에 쌓인 데이터를 가지고 새로운 비지니스를 창출할 수도 있다. 추가적으로 일정 거리 이상 멀어지면 신호의 강도가 약해지는 블루투스의 특성을 이용하여 이용자가 가방과 일정 거리 이상 떨어질 경우, 스마트폰으로 팝업 창을 띄워주는 형태로 분실 방지 기능을 제공해 줄 수도 있다.
