In this paper, a client-side framework for processing of the profile that is necessary for providing adapted content to user's context in the client is designed and implemented. The profile must be constituted context information and various user's information for providing the adapted content to user's context. The client device also provides functionalities such as the creation, the management, and the transmission of the profile. The profile which is used in the proposed profile framework consists of various related information of a user for content adaptation. The technology such as creation, transmission and manage of the profile for effective processing is proposed and apply this technologies to client profile framework during the design are applied. As the result of evaluation, techniques of the proposed framework for processing profiles is more effective than previous techniques.

In this paper, the management architecture and the ubiquitous profile based on CC/PP for contents adaptation in the ubiquitous environment is designed. The components and the attributes of the ubiquitous profile are defined based on the services scenario of contents adaptation in the ubiquitous environment. The ubiquitous profile was applied to techniques such as standard vocabulary, CC/PP structure, RDF schema and RDF to use effectively in the ubiquitous environment during the design. Also we design and propose the another management architecture based on ideas such as the dynamic constitution method, the metadata constitution method using a repository and the management method of gateway on center for the effective management of the ubiquitous profile. The result of performance evaluation for the proposed management architecture is more effective compared with the previous management method of the profile. The proposed the ubiquitous profile and the management architecture has provided the foundation of the research for a user to adaptation contents services in the ubiquitous environment.

Contents adaptation is a technology which converts one content to another content used in various devices. Specially, synchronization of inter-media which are included in a document is needed. There are various proposals and solutions for synchronization of inter-media. In the paper, I present "TATS : Temporal Aggregate Tree Strategy" model, which is used for specifying the temporal relationship among media in series of time. In the TATS model, aggregate tree, a sort of a binary tree, is generated from the execution time of those media. Using this aggregate tree, I implemented the inter-media synchronizations.

This paper proposes a context gathering system that obtains user's environment information from sensor and generates user's context profile. To design the system, we classify context and design context model based on traditional context-aware computing. The proposed system supports contexts adaptation service by gathering user's environment characteristics and biological characteristics and generating user profile.

People access web contain via PC and many other devices. In other words, not only they access information by a PC connected internet, but also they get information through a mobile phone, a PDA even D-TV. In this article, to resolve the problem, we suppose new web caching mechanism called 'SOP(Shared Object Page)'based on applying of meta data of web page information and storing adapted objects.

This paper proposes the system to manage profiles effectively that are necessary for content adaptation services. The proposed profiles for providing content adaptation services are used in the various services. However, currently, there are lack of the interoperability in profiles due to the different configuration, which is affected by different services. The service providers also spend a lot of operating costs by operating profiles respectively. To solve theses problems, the system which can integrate and manage the various kinds of the profiles is necessary. Based on profile services architecture and the previous profile research to the necessary functions for the proposed integrated management system of profile are derived. The proposed integrated management system of profile supports also the functions such as receiving, processing, saying, managing, providing and supports profiles that are made of RDF form and comply with the CC/PP specification. The metadata constitution technique and dynamic technique for effective content adaptation also are applied. As a result of performance evaluation the proposed techniques improve the performance 4% compared with the previous techniques.

This study aims to analyze the cultural intelligence and it's relationship with cross-culture adjustment satisfaction, and performance, and then, we prove the moderating role of international experience between cultural intelligence and cross-culture adjustment with staying in the host country. An exploratory pilot study was conducted with a sample of 188 Chinese expatriates working in Korean company in Korea. Then, we proved the moderating role of international experience between cultural intelligence and cross-cultural adjustment. The results of this study have three implications for human resource development. First this study expanded the research of CQ up to the area of empirical investigation. Second, the empirical findings also supported an incremental and predictive validity that CQ increased explained variance of cross-cultural adjustment. Third, the moderating role of international experience in this study showed the importance of both CQ and international experience with staying in the host country.

In this paper, we design an intelligent loaming management logics which provide personalized teaming considering adaptive learning content dement and content sequencing. We enhance the existing functional model including adaptive learning management functions. Also, we present a system architecture to implement the adaptive learning management system. We realize the adaptive teaming management system based on the SCORM run-time engine.

The development of digital technology has not only brought many changes to our lives, but also many changes to the online education environment. The emergence of micro-learning is to meet the needs of individual learners who hopes to receive personalized learning content immediately when they need it. Therefore, Micro-learning can be said to be 'adaptive' education. This research attempts to explore the development principles of adaptive micro-learning through literature research and case analysis. The results of the research draw four aspects of the development principles, including adaptive learning environment, adaptive learning content, adaptive learning sequence and adaptive learning evaluation, as well as detailed elements of each aspect. Micro-learning is a new form of e-learning that reflects the needs of the current society. As exploratory research, this research attempts to point out the direction for future follow-up research.

This paper describes, in order to extract contour from topographic map image, an adaptive segment-length thresholding using a threshold depended on target image. First of all, after recognizing the primary symbols and detecting two edges from the projection histogram of the elevation value area, the threshold value is determined by the distance between the edges. Then, the subdivision is peformed by searching a branch point and erasing its neighboring Hack pixels. And contour components are extracted by segment-length thresholding. The experimental result shows that the final image contains non-contour component of 2.41% and contour one of 97.59%.
