  • Recently, the organizations related to cultural contents are gradually expanding access to cultural contents for general public through the distributed network. However, since cultural contents have different characteristics than general contents, the objects, the of cultural contents seldom contain the words generally used for organization and search of information. If the cultural contents system is created without any consideration of such differences. We cannot effectively identify and search resources. Moreover, because the names, expressions and meanings are different between metadata elements of various cultural contents, it is very difficult to interconnect or share information between different systems. In order to solve these problems, proper organization ad management of metadata is vital. In this studym we have comparatively analyzed the data elements of each format based on Dublin Core, EAD, VRA, CDWA, CIMI, and Object ID, the metadata formats approached from various aspects in the cultural contents area. Through this study, we tried to provide the basic materials for integration of cultural contents by securing interoperability of different metadata formats.

  • 본 논문에서는 사용자 중심의 커뮤니티를 정의하고, 사용자의 맥락 정보를 이용한 커뮤니티 구성 방법과 맥락정보 변화에 따른 동적 커뮤니티 재구성 방법을 제안한다. 최근 유비쿼터스 스마트 공간에서 협업 서비스를 제공하기 위한 방법으로 커뮤니티 컴퓨팅에 대한 관심이 증대되고 있다. 하지만 기존 커뮤니티 컴퓨팅 관련 연구에서는 정적인 커뮤니티 구성으로 인해 사용자의 행동 변화에 따른 커뮤니티의 동적 구성이 어렵다. 따라서 커뮤니티를 사용자의 행동에 따라 구성하기 위해서는 사용자 맥락 정보를 이용하는 것이 필요하다. 제안된 방법은 사용자 중심의 정형화된 맥락 모델을 이용하여 사용자의 관심사를 추론하고 커뮤니티의 목적을 설정한다. 그리고 주기적인 사용자의 맥락 정보 감시를 통해 사용자의 행동 변화에 따라 동적으로 커뮤니티 재구성이 가능하게 한다. 커뮤니티 관리 모듈은 사용자의 맥락 정보를 이용하여 구성원들 사이의 관계성을 분석하고, 분석된 관계를 바탕으로 커뮤니티의 특성을 결정한다. 제안된 기법의 유용성을 검증하기 위해서, 맥락인식 기반의 증강현실 경험 공유 시스템을 이용하였고, 사용자의 맥락 정보의 변화에 따른 동적 커뮤니티 구성과 커뮤니티 구성원들간의 콘텐츠에 대한 선택적 공유를 실험하였다. 제안된 방법을 활용하면 선택적 공유를 위한 동적 커뮤니티 구성이 가능하게 될 것으로 기대된다.

  • Recently, many cities around the world introduced and operated shared bicycle system to reduce the traffic and air pollution. Seoul also provides shared bicycle service called as "Ddareungi" since 2015. As the use of shared bicycle increases, the demand for bicycle in each station is also increasing. In addition to the restriction on budget, however, there are managerial issues due to the different demands of each station. Currently, while bicycle rebalancing is used to resolve the huge imbalance of demands among many stations, forecasting uncertain demand at the future is more important problem in practice. In this paper, we develop forecasting model for demand for Seoul shared bicycle using statistical time series analysis and apply our model to the real data. In particular, we apply Holt-Winters method which was used to forecast electricity demand, and perform sensitivity analysis on the parameters that affect on real demand forecasting.

  • The smartphone allows learners to be involved in learning environments in which students actively study from anywhere and at anytime. Because learners can keep engaged in the environment where they can access to the internet, they can efficiently study in transit using various features and functions of smartphone. Smart learning is a unique learning based on mobility and functions of mobile digital devices including searching and sharing information and using various applications. For the effective use of smartphones in e-learning systems, the contents and learning management systems should be designed to meet effective teaching and learning principles, such as interactivity and collaborations. In smart learning, learning contents for effective learning need to be integrated with typical functions of smartphones and to develop small pieces of learning contents according to learning topics. In the case of learning management systems, it should reflect understanding of learners' environment using a PA agent program and provide personalized learning services.

  • In distributed file-systems, cooperative caching algorithm which owns the data cached at each node jointly is used to reduce an expense of disk access. Cooperative caching algorithm is the method that increases a cache hit-ratio and decrease a disk access as it holds the cache information of distributed systems in common and makes cache larger virtually. Recently, several cooperative caching algorithms decrease the message costs by using approximate information of the cache and increase the cache hit-ratio by using local and global cache fields dynamically. And they have an advantage that increases the whole field hit-ratio by sending a replaced buffer to the idle node on buffers replacement in order to maintain the replaced cache in the cache field. However the wrong approximate information deteriorates the performance, the consistency maintenance goes to great expense to exchange messages and the cost that manages Age-information of each node to choose the idle node increases. In this thesis, we propose a cooperative cache algorithm that maintains correct cache information, minimizes the maintenance cost for consistency and the management cost for buffer Age-information. Also, we show the superiority of our algorithm through the performance evaluation.
