In this study we develop core technology of Multi-Charmel Voice Guidance System based on active 2.45GHz RFID that can be used in the field of advertising. Through this, we can service more familiar with voice information to foreigners by own language in large scale international event. As an alternative to the current high-expensive voice guidance system in exhibition hall and provide more value added services to user. As the result, we present the configuration of integrated software platform which include media server, media client and receiver. It can be as a basis infra equipment for a signtseeing in RFID/USN environment. Additionally through tag information analysis about exposure of advertisement that is collected late, supposed system may achieve role as a new marketing tool.

Recently, value added location based service and convergence monitoring and control system is growing. The cases include increasing usage of smart-phone for taking picture, wireless network, GPS and digital map. Especially, Smart-phone is appropriate for using image information and location information. However it is possible to be exploited for forgery and manipulation. So we experimented on transferring modified data on the smart-phone as image and location information in EXIF and researched the technology for data verification. In addition, we have designed security monitoring and control prototype considering axis-address matching analysis used geocoding, watermarking verification, encryption.

It is a very important to manage inventory quickly and accurately in Refrigerated commercial warehouses in which a lot of logistics are often shipping and receiving. Because most of systems for managing refrigerated warehouses consist of COBOL, it will be raised maintenance costs. There is no service for consignees who are consumer of refrigerated warehouses and they use only a fax or a phone for orders. In this paper, we design a mobile framework based on smart phones and supporting a variety of value-added services which are fit consignees, solving problem of outdated legacy systems and no services for consignees. We also implement the mobile framework which is consists of the JSP server and the android clients.

As a settlement for the fiber access, the FTTH is an ideal mode for providing various high-bandwidth value added services including high definition IPTV to broadband users, and KT, the largest incumbent of Korea, started FTTH service from 2005. For FTTH deployment, it needs a cost-effective solution including reliability and maintenance costs. This paper analyzes the characteristics and technical issues for the main components of outside plant in general household area.

This study was conducted the physicochemical and sensory characteristics of cookies added with Angelica gigas Nakai powder(0~2.5%). The pH of the samples ranged from 6.13 to 6.27, and the density ranged from 0.99 to 1.15. Increasing the amount of Angelica gigas Nakai powder in the cookies decreased the spread factor of the cookies and tended to decrease lightness(L) and yellowness(b) in the Hunter color value with redness(a) increased. For the textural characteristics, the addition of Angelica gigas Nakai powder increased strength and hardness. The sensory evaluation showed that the cookies with Angelica gigas Nakai powder were preferred more than those without in color, odor, texture, taste and overall preference. Especially, cookies with 1.5% of Angelica gigas Nakai powder were valued as best.

The types of service using location Information are being various and extending it's domain as wireless internet technology is developing and it's application part is widespread, so it is prospected that LBS (Location-Based Services) will be killer application in wireless internet services. This location information is basic and high value-added information, and this information services make prior GIS (Geography Information System) to be useful to anybody. The acquisition of this location information from moving object is very important part for these LBS. After this, when LBS is familiar to everybody, we can predict that LBS system load is so heavy for the acquisition of so many subscribers and vehicles. Moving object database (MODB) system manages objects like subscribes and vehicles that are moving and have telecommunication terminal checked one's location. MODB is consists of 4 part, moving object location acquisition part, moving object location storage part, moving object query processing part, and moving object application p art. In this MODB system, acquisition of moving object location part must provide guarantee location information as well as reduce telecommunication overhead. In this paper, we study of problems in acquisition a huge number o f moving objects location and design some acquisition strategies to reduce telecommunication overhead. And after implementation these strategies, we estimate performance of this system and quality of information.

선진 전력시장에서는 오래전부터 전력부가서비스의 중요성을 깨닫고, 전력부가서비스와 전력부가서비스 지원을 위한 인프라에 관하여 다양한 연구와 시도가 지속적으로 이루어지고 있다. 한편, 국내에서는 전력 부가서비스를 인식하고는 있지만 아직까지 이와 같은 연구와 개발이 활성화되지는 못하고 있다. 그러나 전력부가서비스는 전력시장의 변화가 만들어낸 결과물로써, 시간이 흐를수록 그 중요성은 더욱 증가할 것이다. 또한 전력부가서비스 시장은 아직까지 미개척 분야가 많은 블루오션이므로, 국내시장 및 아직까지 전력 부가서비스가 도입되지 못한 해외전력시장에도 진출할 수 있는 가능성을 가진다. 본 논문에서는 초기단계인 만큼 가능성과 위험이 공존하는 국내의 전력시장에서 성공적인 전력부가서비스를 개발하기 위해, 세계적인 전력시장의 변화와, 이 변화가 국내 전력시장에 미친 영향, 그리고 국내 시 장의 전력부가서비스 환경을 분석함으로써 국내 환경에 적합한 전력부가서비스 BM을 개발하고 이를 시스템으로 구축하는 방안에 대하여 소개하고자 한다.

The information of figures in science which could induce interest in science and have educational importance is the value-added content through information sharing and connectivity. In this study, we analyzed domestic and overseas cases of Linked Open Data(LOD) that are being increased recently in order to provide a better service through information sharing and utilization of scientific figures. We suggested an efficient scientific figures ontology and the method for LOD construction reflecting the results of the analysis. We also presented plans for the interlinking among various external resources and for promoting LOD information use.

Recently Korean textile industry has been in the phase that requires its strategy change from the less-develped country style of the labor-intensive products to the developed country style of the technology-intensive products. It needs to make more efforts to develop the value-added products to meet the customer's various needs. In addition, development of technology, equipment, and design is required to implement its corporate strategy successfully. Although Korean textile companies have currently kept skillful labor and advanced equipments, they are losing their share in the international textile markets. This is mainly because corporate management has not been involved with efficient strategy. Strategy is an adoption of a company to environment by its corporate members, thus leading to the requirement of coordination of the main functions such as manufacturing and marketing. In fact, the coordination of the two departments toward reaching the corporate goal is not easy since the two are interested in different areas, respectively. Manufacturing people show their interests in production capacity, equipment layout, process technology, quality, purchasing, and labor while marketing people, target customer, product mix, advertisement, product specification, and customer service. For this reason, conflicts sometimes happen between the two departments. There are, however, many area that need a horizontal cooperation, for instance, in layout, process technology, product mix, and potential demand. Therefore, reciprocal coordination is necessary for achieving the firm's common objectives. This study was concerned with determining the factors that enhance the competitiveness of textile firms so that they could reach the common goal of the two departments with a horizontal collaboration.

Science and technology information data is steadily increasing not only in Korea but also around the world. At present, dozens of documents are produced and distributed every day regardless of field, and researchers are increasingly demanding to use this information effectively to support research activities that are valuable and useful for human life. In the past, researchers are moving away from searching for necessary information, and now they are changing to services that connect data and data, find high value-added information that can be used, and present it to researchers. In this study, we analyze literature data created by Korean researchers from domestic and foreign scientific and technological information data, find use cases, and provide information to help researchers.
