At present, most Electronic Commerce System is made mainstream of Server-Client Commerce. For searching goods information, we must entering the EC sites and search that s information. but, P2P(Peer to Peer) System being escape traditional structure, Server-Client, it enable information transact between users, and resolve the problem of network, add-cost of server-ensurance, etc. Also, it is possible to trade information between person to person, client to provide. In this paper, we investigate on-going p2p models and study on the p2p based control based system.

There are two major factors to use NoSQL in order to manage Big Data; to increase productivity of an application programmer and to increase data access performance. But, in many business fields, this hopeful plan lacks careful consideration. For efficient and effective management and analysis of Big Data, it is necessary to perform a test with the expectation for productivity and performance of the application programmer before deciding whether NoSQL technique is used or not. In this paper, we research on programmer productivity, data access performance, risk distribution, and so forth.

For Many enterprises are creating and handling huge amount of data in their business administration. However, it would be impossible for general databases such as Relational Databases, hierarchical databases, and network databases to manage and analyze this large amount of document data efficiently and effectively. So, in this paper, we define document databases and check out their characteristics such as consistency and transaction. And we propose appropriate or inappropriate subjects for application of document databases.

Decision procedure was done with the evaluation of multi-criterion analysis. Importance of each criterion was considered through heuristically method, specially it was based on the heuristic least mean square algorithm. To consider coalition evaluation, it was carried out by calculation of Shapley index and Interaction value. The model output is also analyzed with the help of those two indexes, and the procedure was also displayed with details. Finally, the differences between the model output and the desired results are evaluated thoroughly, several problems are raised at the end of the example which require for further studying.

Pharmaceutical companies over the world are exposed to risks of lessened sales and negative impact on corporate image due to circulation of counterfeit drugs, which eventually threatens safety of patients. thus, in order to eradicate distribution of counterfeit drugs, many countries are taking initiatives to legalize and set serialization through e-Pedigree, which is based on RFID technology or barcode system to track and trace distribution of drugs from point of manufacturing to usage. therefore, this study contemplates domestic and international management system of medical drugs and suggests application methods of e-Pedigree based on RFID technology that promotes safety of patients and distribution of drugs.

인터넷의 사용 증가로 정보의 양은 기하급수적으로 증가하고 있으며 웹 데이터의 표준인 XML의 데이터 표현의 유연성으로 인해 EDMS(Electronic Document Management Syste), ebXML(e-business extensible Markup Language)등 웹 기반의 전자문서를 이용하는 XML를 문서 교환 및 표준 문서 형식으로 도입하고 있는 실정이다. 이런 XML문서들을 저장관리 하기 위해 XML전용 Database도 현재 많이 연구되고 있다. 하지만 이런 XML전용 Database들은 관계형 데이터베이스보다 실용성이 떨어지는 점들이 많아 XML과 관계형 데이터베이스 매핑에 대한 연구도 활발히 진행중이다. 본 논문에서는 $C{\sharp}$을 이용하여 XML과 관계형 데이터베이스 간의 매핑을 위한 모듈을 개발하였으며, XML의 element와 관계형 데이터베이스의 필드를 상호 매핑시켜 줌으로 인해 XML문서의 element를 정확하게 저장, 관리 할 수 있다.

As the Internet connections and services at U.S. public libraries have increased dramatically since 1990s, defining, assessing and measuring quality of these new electronic services have become a critical issue. This research was a study designed to identify key dimensions of Internet service quality at public libraries by providing a systematic framework for measuring and assessing the quality of Internet services. The study used modified SERVQUAL and SERVPERF instruments which have been widely used service quality measurement in business marketing areas and LibQUAL+ model which are widely adopted service quality measurement instrument in most of the academic libraries in U.S.

L Company is producing the second sept pin, Shadow Mask which is the chief part of CRT in W, Monitor. Inside of the CRT pan, Shadow Mask leads the electronic beam to express the three primary colors; red, green, blue, and it is the core part to embody the colors. In the etching process, it produces this part with manufacturing by eroding the iron chloride. Even though the iron chloride is harmless to human body. it is necessary to diminish the amount of it on the view of preservation of environment. In addition, by studying the method of the dispossed liquid process, cutting down the manufacturing cost is a necessary task on the aspect of reconsideration of competitive business. This study shows the case that through the six sigma innovation activity, it reforms the following the former processing flow, and it reduces the amount of it by improving the efficiency of the iron chloride. By rationalization of the standard requirement cooperative company, it could cut down the manufacturing cost in the cooperative company, so it could promote the common profits.

Security systems for inland cargo truck transportation are mostly limited to route tracking for safe and efficient transportation. With this route tracking system, the status of cargo trucks can be monitored easily within inland boundaries. In case of oil transportation by land, however, security systems ensuring transportation of a designated quantity of products have been subject to extensive research since thefts and substitution by a similar product in the transportation process have emerged as a social problem. Security devices installed in an oil tank truck must meet the explosion-proof performance standards and be applicable to varying types of trucks. Accordingly, a wireless electronic seal with RF communication functions is considered to be the most appropriate method, but e-seals on moving vehicles require such levels of performance and reliability that can overcome certain challenges including changing radio waves and topographical impediments. Considering these characteristics of oil tank trucks, this study proposes an stabilization method to enhance the RF communication performance of e-seals, based on radio simulation and experiment findings.

e-Business in healthcare sector has been called e-Health, which is evolving into u-Health with advances of ubiquitous technologies. Seamless information sharing among health organizations is being discussed in many nations including USA, UK, Australia and Korea. Efforts for establishing the electronic health record (EHR) system and a nation-wide information sharing environment are called NHII (National Health Information Infrastructure) initiatives. With the advent of u-Health and progress of health information systems, information security issues in healthcare sector have become a very significant problem. In this paper, we analyze several issues on health information security occurring in u-Health environment and develop an information security standard for protecting health information. It is expected that the standard proposed in this work could be established as a national standard after sufficient reviews by information security experts, stakeholders in healthcare sector, and health professionals. Health organizations can establish comprehensive information security systems and protect health information more effectively using the standard. The result of this paper also contributes to relieving worries about privacy and security of individually identifiable health information brought by NHII implementation and u-Health systems.
