최근 건설산업은 해외건설 수주액 증가에 따른 외형성장은 이루었으나, 시공분야에 집중되고, 고부가가치 영역인 건설ENG 분야의 해외시장 점유율 및 경쟁력은 극히 낮은 수준이다. 또한 대형 건설ENG 업체와 중 소형 건설ENG 업체 간에 건설수주액을 비롯하여 기술경쟁력에서의 양극화가 심화되고 있다. 특히 기존 건설ENG 관련 정보시스템은 설계 시방기준 등 단순 자료축적을 통한 정보제공이 대부분이며, 실제 건설ENG 업계에서 필요로 하는 정보제공 및 지원이 미흡한 실정이다. 본 연구에서는 건설ENG 업계가 실제 필요로 하는 건설기술지식정보에 대한 공유 체계의 마련을 통해 건설ENG 분야의 기술력 향상을 지원하고자 하였다. 이를 위해 발주청과 건설ENG 업체 사용자 간에 직접 필요한 정보의 요청 및 제공 등 노하우를 상호 교환 공유할 수 있도록 시스템 구축과 운영 방안을 제시하였다. 이를 통해 유사 건설사업의 수행 시 신속한 정보제공을 통한 업무처리시간의 단축으로 업무효율성이 증대되리라 예상된다.

환경오염과 차량 성능향상에 따라서 날로 강화되는 연비규제는 차량용 변속기로서 CVT 양상 보급에 대한 필요를 앞당기고 있다. CVT는 소형차를 중심으로 일부 자동차 에이커에 의해 이미 실용화되어 있으며 일본 및 구미 자동차 각 사는 CVT에 대한 자체기술을 보유하고 경쟁성 있 는 완성품 개발을 위하여 총력을 기울이고 있는 실정이다. CVT에 대한 연구개발의 추세는 동 력전달 구동요소의 특성에 따라 벨트식과 토로이달 (Torodial)식으로 구분할 수 있으며 대부분의 경우 현재 일부 실용화 개발된 벨트식 CVT가 기술완성도가 높은 반면 토로이달롤러의 각도를 연속적으로 변환시킴으로써 무단변속을 이루는 토로이달 방식은 2000년대 이후에 양산을 목표로 일본 및 영국 등에서 개발 진행주이나 새로운 재질과 제어기술개발 등의 숙제를 안고 있다. 벨 트식의 경우 금속벨트는 지난 십 수년이상 시행착오를 겪으며 CVT용으로 개발된 전문업체의 제품이 이미 특허화되어 있기 때문에 자동차 각사는 벨트와 같은 구동요소보다는 CVT 메카니즘 설계 및 제어시스템 개발에 기술력을 투입하고 있다. 따라서 국내 CVT 개발도 이와 같은 추세를 따를 것으로 기대되고 있으나 AT와 같은 완성품으로서의 상품가치를 갖기 위하여는 CVT에 대한 보다 많은 연구개발이 필요하다고 생각된다.

Companies often use database for performing task more efficiently and data mining for marketing and production efficiency through analyzing of the stored database. The use of the knowledge through the data mining maintains and provides a direction of development for the company. It could be as an additional competitive power for the company when decision making is necessary. This study is designing a model that predicts a rating of existing customer and consumption pattern with using actual data of the manufacturer and data mining methodology. The objective of this model is to improve profits for the company and brand value through connecting the marketing with identifying the customer's rating and consumer behavior.

초고령화 사회로 진입하면서 건강의 유지 및 관리는 일상생활에서 매우 중요한 관심으로 대두되고 있다. 특히 우리나라 전통의학에 대한 가치성이 향상되면서 이를 실생활에 접목하기 위한 노력이 활발하게 진행되고 있는 실정이다. 이를 위해 본 논문에서는 사상의학에 대한 체질 분류의 객관화를 통해 예방차원의 건강 관리를 지속하기 위한 연구를 진행하고자 한다. 특히 사상의학에서 제안하고 있는 여러 사상체질 분류 방법 중에서 음성을 통한 사상체질 분류 방법을 공학적으로 구현하여 이를 객관적 진단 지표로 설계하고자 한다. 따라서 본 논문에서는 서울지역에 거주하고 있는 20-30대 남성의 음성을 수집하여 음성 분석학적 요소 중 피치 분석 요소들에 대한 추출 및 비교를 통해 사상의학의 사기론에서 제안하는 이론적 근거를 입증하고자 한다. 최종적으로 실험을 통해 추출된 결과를 사상의학 전문의의 진단 결과와 비교, 분석하여 제안하는 기법에 대한 검증을 수행하고자 한다.

As VANET(Vehicular Ad-hoc NETwork) improves road safety, efficiency, and comfort, and provides a value-added service such as commerce information or internet access. it is the most important technology in ITS(Intelligent Transportation System). But, In VANETs, better communication efficiency can be achieved by sacrificing security and vice versa. VANETs cannot get started without either of them. Therefore, to solve these problems simultaneously, this paper proposes MAC(Message Authentication Code) based SDAP(Secure Data Aggregation Protocol) which removes redundant data or abnormal data between vehicles and verifies the integrity of message. The MAC based SDAP not only improves the efficiency of data delivery but also enhances the security by detecting malicious attacks such as propagation jamming attack, forgery attack, and disguised attack.

Digital documentation is now becoming a must throughout a building process including design, construction, inspection, procurement and even facility management. The Internet is a backbone of such process, and web-based information exchange is the standard among other mainstream technologies. The current information management techniques, however, is heavily dependant on the server-side processing, which naturally results in the overload of the overall system. This paper proposes an XML-based approach in order to resolve such problems. A VE system was developed to demonstrate the efficiency of the XML solution, in term of efficient VE data management and fast decision making. also in this paper suggests 1) introduce XML based DBMS to improve data management efficiency and 2) introduce Mobile Computing to improve data accessibilities on sites.

Recently, basic literacy education related to digital literacy and data literacy has been emphasized for students who will live in a rapidly developing future digital society. Accordingly, demand for education to improve big data and data literacy is also increasing in general universities and universities of education as basic knowledge. Therefore, this study designed and applied big data analysis courses for pre-service teachers and analyzed the impact on data literacy. As a result of analyzing the interest and understanding of the input program, it was confirmed that it was an appropriate form for the level of pre-service teachers, and there was a significant improvement in competencies in all areas of 'knowledge', 'skills', and 'values and attitudes' of data literacy. It is hoped that the results of this study will contribute to enhancing the data literacy of students and pre-served teachers by helping with systematic data literacy educational research.

Recent reports about economic structure and changes show that global economy changes to rely on service rather than manufacturing. This phenomenon can be explained in two ways: the growth of service industry itself and the increasing reliance on service by other industry areas. The importance of service is indicated by the fact that the contribution of research and development, marketing, and finance to the revenue generation of companies is getting greater than that of manufacturing. This change in the economic structure calls for researchers' attention on the importance of service and the service-based economy. In the service-based economy, firms are considered value proposition providers and consumers actual value creators so that the concept of co-value creation becomes a key thesis to study. However, there are a variety of definitions of service and diversified measurements of service anchored in the supplier-oriented understanding of service yet. This lack of understanding of the service and the economic paradigm change causes a lot of problems in the areas of service productivity, service quality, and service innovation. Even though a new movement called service science started and rigorously pursues the way of enhancing the understanding of the economic change and service productivity, there is no framework that provides a unified view about the new role of service, service productivity, service quality, and thus service innovation. This study proposes a unified framework to provide a structured view about service provision and to facilitate the research on service. The framework is built on the concepts from previous studies about service marketing and service science: service life cycle and service networks including value activity network, resource integrator network, and capability network. We hope this study can be used as the basis for future studies on service science.
