The growth in number and efficiency of smart devices such as GPS enabled smart phones and PDAs present an unparalleled opportunity for diverse areas of life. However extraction of GPS traces for provision of services demand a huge storage space as well as computation overhead. This is a challenging task especially for the applications which provide runtime services. In this paper we provide a simplified model to extract GPS traces of moving objects at runtime. Road segment partitioning and measure of deviation in angle of trajectory path is incorporated to identify the significant data points. The number of these data points is minimized by our proposed approach in an efficient manner to overwhelm the storage and computation overhead. Further, the competent reconstruction of complete itinerary based on gathered data, is also ensured by proposed method.

LTE is the outstanding technology to transfer the data and voice. LTE consists of several nodes to transfer data. In case of the failure in the node of LTE, it could not support the service. So telecommunication-providers set up the back-up system for the simultaneous service-provision. But there is still the problem it comes to the network. Even though there is a back-up system, it would be useless the network is down. We propose the scheme to support the service in the case of this network problem in the LTE network. This scheme reduces 23% load in the LTE network in the case of the HSS node's failure or the network to the HSS nodes.

소셜 네트워크 서비스와 모바일 단말의 보급이 증가함에 따라 사용자들은 커뮤니티를 형성하고 이를 통하여 즉시적으로 문제(Needs) 해결에 필요한 사용자들간의 경험 정보를 공유하고자 한다. 기존의 커뮤니티들은 특정 의도로 형성된 공동체로써 사용자의 위치 및 사회적 관계 보다는 단순히 카폐 개념의 공동체를 형성한다. 사용자의 위치가 변경됨에 따라 원하는 정보를 제공하는 방법에 있어 사용자의 장소/사회적 관계를 고려하여 즉시적으로 필요한 커뮤니티를 추천 검색하거나 신규 커뮤니티를 생성하여 사용자들의 참여를 통한 정보 공유 및 사용자 위치에서 발생되는 여러 이벤트를 수집할 수 있는 소셜 레이더 기능이 필요하다. 또한 형성된 공동체를 통하여 서비스 실행에 필요한 실행환경을 공유하여 소셜 네트워크 서비스를 제공받고자 한다. 본 논문에서는 사용자가 존재하는 공간 내에서 서로 공유될 수 있는 정보를 추적/검색/추천/공유할 수 있는 사용자 위치 기반 소셜 레이더 관리 시스템에 관한 구성 방법을 제공한다.

In semiconductor IP reuse, precise understanding of semiconductor IP interfaces is essential for integrated chip design. However, in general, these interfaces are described in the original designer's description style. Furthermore, their description method are not unified, so it is very difficult for the chip integration designer to understand them. This paper proposes a standardized description method of semiconductor IP interfaces. It consists of 9 items such as IP information, description level, model provision, data type, interface information, port information, signal information, protocol information, and source file. The proposed method helps the chip integration designer to understand semiconductor IP interfaces and to integrate them into a single chip.

This study investigated the current state of online subject guides in Korean academic libraries and suggests improvement. Through the examination of 100 academic libraries' Web sites, only 14 online subject guides were identified, showing that the development of online subjects guides in Korea is still in infancy. The examined online subject guides were evaluated as high quality in terms of accessibility, integration of information resources, and format consistency, but low quality in the provision of specialized subjects, user instruction, and information retrieval systems. An online subject guide should be a one-stop service that provides fast access to information resources along with subject-specialized user instruction and effective communication with librarians.

Purpose: The purpose of this research was to identify the effects of providing an information service program by media on preoperative anxiety and postoperative educational satisfaction in patients with cataract surgery. Methods: For this study 52 patients who visited the ophthalmology clinic at P Hospital in B metropolitan city and who were scheduled to undergo one-day cataract surgery under local anesthesia were recruited. The 52 patients were assigned to the experimental group (25) or the control group (27). This study was conducted from August 27, 2015 to May 29, 2016. Results: Following the provision of cataract surgery related information service by media, the experimental group had a lower mean score for anxiety and higher mean score for educational satisfaction compared to the control group of patients. Conclusion: Results indicate that information service program by media "Goodbye Cataract" is useful educational materials for cataract patients in outpatient department and outpatient operating rooms.

This paper proposes two methods for the construction of job offer and job hunting information in order to supply an environment that can easily connects to job hunting information. First, the database expansion, category rules and ERD(Entity Relation Diagram) are designed for the construction of job hunting site with real example. Second, the prime number labeling rules are designed for the strong intimacy of label rules. Therefore, according to using the systematic and regular rules when we design and construct a database, the consistency and efficiency are improved in the database being constructed and being operated. And the convenience of application program development and operation are easily provided. In addition, the proposed code-expansion rule can be defined and be standardized in the domestic and foreign job offer and job hunting information provision agency.

NFPs support a sustainable society and they rely on contributions from donors. Donor behavior is a kind of consumer behavior that influences fundraising by NFPs. In order to make fundraising functional under a principal-agent relationship, NFPs must construct trust through proper provision of accounting information. For donors, financial statements are main source of accounting information. Edelman revealed that the level of trust in Japan's NFPs is the lowest in East Asia, because of a lack of transparency and accountability. Some researchers had investigated donor behavior as a kind of consumer behavior and had provided supportive results that accounting information influences donor behaviors, before this research was conducted. This research investigates this background by conducting questionnaire-based survey. Main questions of this questionnaire were created according to criteria that BBB are using for NFPs in the U.S. The results of this survey revealed the lack of reliability of basic accounting information in Japan and that education in higher educational institutions can improve this situation. This survey also revealed that a rating agency like BBB, which evaluates accounting information of NFPs, could improve trust on NFPs. The implications of this study can apply to the other countries and regions where trust in NFPs is insufficient.

Due to the recent advances in computer technologies and high-speed networks, telecommunication services and provision of multimedia services will be considered a new software architecture adapting networking infrastructure on information networking architecture. In this paper, the video conference services has been selected as a target service example because it is expected to become one of the most important services on the full service network. In fact, it can be viewed as the basis for providing telecommunication services such as video telephony and video conferencing. This paepr presents the prototyping of TINA(Telecommunication Information Networking Architecture) based desktop video conference system using the concepts of session management. The prototyping of deskop video conference system aims at assessing TINA concepts and refinement of the mapping between session graph and connection graph, and provides support of open service platform towards distribution and objected-orientation.

The recommender system (RS) has emerged as a solution to overcome the constraints of excessive information provision and to maximize profit and reputation for information providers. Although the RS can be implemented with various approaches, there is no study on how to appropriately utilize the information generated from the review of the recommended object. We propose a method to improve the performance of RS by using cluster information generated from online review. We implemented the proposed method and experimented with real data, and confirmed that the performance is significantly improved compared to the existing approaches.
