Recently, introduced a cloud computing technology to the IT industry, smart phones, it has become possible connection between mobility terminal such as a tablet PC. For dissemination and popularization of movable wireless terminal, the same operation have focused on a viable mobile cloud in various terminal. Also, it evolved Wireless Sensor Network(WSN) technology, utilizing a Body Sensor Network(BSN), which research is underway to build large Ubiquitous Sensor Network(USN). BSN is based on large-scale sensor networks, it integrates the state information of the patient's body, it has been the need to build a managed system. Also, by transferring the acquired sensor information to HIS(Hospital Information System), there is a need to frequently monitor the condition of the patient. Therefore, In this paper, possible sensor information exchange between terminals in a mobile cloud environment, by integrating the data obtained by the body sensor HIS and interoperable data DBaaS (DataBase as a Service) it will provide a base of mBodyCloud System. Therefore, to provide an integrated protocol to include the sensor data to a standard HL7(Health Level7) medical information data.

With the development of information technology, more and more internet sites are available to consumers. Increasing on the interests of diet and health in modem society, there are numerous internet sites dealing with food, nutrition and health. Considering the importance and expected roles of internet sites in information dissemination in the future world, it is important to put more efforts to encourage internet sites with more accurate an useful information. Up to present, not much work has been done on quality analysis and evaluation of the internet information. This study aimed to develop a model to evaluate and rank the internet information according to its quality so that consumers can be guided toward correct information source. Three models were adapted from the literature for pilot study to develop a model suitable for evaluation of contents of sites related to food and nutrition information. From the pilot study, a evaluation model was developed with criteria more relevant to Korean internet site by expert panel. Evaluation criteria of the model is authority, accuracy, objectivity, coverage, and user-friendliness. For the objective and systematic evaluation, scores were assigned totaling maximum 100 point to each evaluation criteria factors. The model developed in this study could be used as one for other internet sites in area other than food and nutrition.

Since the supply and demand of agricultural products are unstable, which causes instability in farm income and consumer prices, the government has sought to mitigate the problems caused by unstable supply and demand by generating and providing agricultural outlook information. However, research should be carried out to increase the quality and utilization of agricultural observation information, because the value of agricultural observation information increases only when more users use this information and apply it to their decisions. In this study, a survey was conducted targeting producers and experts who are users or potential users of agricultural outlook information, and the results were analyzed through quantitative model, specifically importance-performance analysis (IPA) and analytic hierarchy process (AHP). The results show that improvement of promptness was required among the seven items evaluated with regard to agricultural outlook. Also, measures for dissemination of agricultural outlook information and the contents of outlook information should be improved to increase its use. If the quality level and use of agricultural observation information are increased by reflecting the results of the above analysis, decision-making on the supply and demand of agricultural products in Korea will be improved, and it is thought that it will be possible to increase farm household income and stabilize consumer prices through stabilization of supply and demand of agricultural products.

The purpose of the present study is to improve the effectiveness of Korea's ODA projects on agricultural technology transfer to Africa. This study investigates agricultural extension system of African countries and provides a direction of the systematic strategies of the Korean ODAs on agricultural technology. This study pays particular attention on Africanization of agricultural technology transfer of the Korean ODA strategies. Unlike the previous studies focusing mainly on micro level investigation on the ODA strategy development, the present study incorporates the agricultural technology dissemination system of Ethiopia and Uganda in a macro perspective to develop a desirable form of the ODA strategy. The findings illustrate that the technology dissemination systems of the case countries have different characteristics depending on the function and organization of extension agency. And their functional capability and role segmentation by the extension agency are differently configured, too. In case of Ethiopia, top-down structure for the agricultural extension system has been built. Farmers' group and field agent of the information delivery system has expanded their participation into the system. However, we also find that the system of Ethiopia still lacks effective use of its existing technology, since it puts more emphasis on management aspects than improvement of agricultural productivity for farmers. On the other hand, even though Uganda has established participatory extension system that encompasses the entire agencies of the extension system, government efforts to enhance the extension system are still concentrated on expanding research functions rather than technical dissemination. The results imply that promoting and strengthening localization of the ODA strategy has to be developed to make localization policy of the Korean ODA. The present study concludes with some specific policy implications for necessary conditions of the agricultural development in African countries.

Intelligent Transportation Systems (ITS) is aimed to implement IT(Information Technology) to develop the next-generation transportation system in order to improve traffic conditions. In order to provide traffic information, the methods that provide available traffic informations to the public are needed. In this paper, analysis of the transportation applications in smart-phone and currently available methods of traffic information's sharing and providing were discussed. Finally, OPEN API was discussed and shows its effectiveness for transportation information area especially in smart phone.

상업출판사에 의한 학술정보의 무기화 및 독점화로 학술정보 유통이 일대 위기를 맞고 있는 가운데 누구나 자유롭게 학술정보를 이용하자는 운동이 활발하다. 이를 기술적 표준적으로 지원하기 위해 결성된 OAI에서는 OAI 아키텍쳐와 표준 프로토콜을 개발하였다. OAI는 프로토콜 표준화를 통해 메타데이터의 상호운용성은 크게 증진하였으나, 메타데이터와 전자원문 간 연계를 간과함으로써 정보자원 간 연계가 취약한 맹점이 있다. 본 논문에서는 OAI 아키텍쳐의 메타데이터와 전자원문 간 연계성을 개선하고 유사 자원으로의 확장성을 제공하기 위해, 국제표준 프레임워크인 OpenURL을 접맥한 개방형 학술정보 유통 아키텍처를 설계 및 구현하였다. 이를 통해 분산 환경에서의 정보자원 간 상호운용성 및 유사자원으로의 확장성을 제고하였다.

Recent developments and integration of IT are expanding the possibility of various instructional learning methods in education environments. Contemporary learning theory such as open education, self-directed learning, student's centered learning describes the students as an active and engaged information user and underscores the importance of information literacy. Therefore, school library today focus on the process of learning-teaching process rather than dissemination information, and emphasized the focus of the school electronic library as information center. The purpose of this study is examined physical components of School Electronic Library, design a model of information system and suggests a strategy for implementing teaching-learning process support services based on school electronic library and information system.

인터넷 인프라의 보급과 이용인구의 급속한 증가는 off-line을 통해서 물리적으로 획득하던 다양한 정보와 자료를 인터넷을 통해서 쉽고 빠르게 이용할 수 있는 서비스를 창출하고 있다. 그러나 이와 같은 서비스를 통해서 제공되는 컨텐츠의 저작권 문제와 불법 복제 등과 같은 피해도 함께 증가하고 있다. 이런 문제를 해결하기 위해서는 컨텐츠에 접근하고 이용할 수 있는 자격을 가지고 있는 사용자만이 해당 컨텐츠를 정상적으로 이용할 수 있도록 하는 Access Control(AC) 기술이 함께 연구되고 있다. 현재 상용화되어 있는 CAS와 DRM은 PBT 형태의 대표적인 AC 기술이라 할 수 있다. 본 논문에서는 [5]에서 제시된 PFT 기반의 AC를 위한 Security Architecture를 살펴보고, 효과적인 운영을 위한 PFT 기반의 새로운 AC 구조를 제시한다.
