It is not easy for business workers to find proper information for his job, because of the following problems:(1) information exist in various information system both internal and external with diverse formats(2) he cannot estimate relevance of all the information and (3) he cannot select proper information among large volume of information. The requirements for the systems are the following things:(1) search of relevant information from various internal and external information systems(2) proving an integrated view of information for workers, and (3) information processing and decision-making are seamlessly integrated fro business workers. We proposed an agent system to fulfill the requirements. We focus on the purchasing job, and developed a prototype system. PIPA(Purchasing Information Process Agent). The PIPA performs not only information processing jobs(information search gathering, display, business form -making)but also decision-making support job (evaluation of supplier candidates, and apply of sourcing policy) for sourcing manager. The framework of the PIPA can be appled to other information processing and desision-making jobs.

The owner of underground metallic structures (gas pipeline, oil pipeline, water pipeline, etc) has a burden of responsibility for the corrosion protection in order to prevent big accidents like gas explosion, soil pollution, leakage and so on. So far, Cathodic Protection(CP) technology have been implemented for protection of underground systems. The stray current from DC subway system in Korea has affected the cathodic protection (CP) design of the buried pipelines adjacent to the railroads. In this aspect, KERI has developed a various mitigation method, drainage system through steel bar under the rail, a stray current gathering mesh system, insulation method between yard and main line, distributed ICCP(Impressed Current Cathodic System), High speed response rectifier, restrictive drainage system, Boding ICCP system. We installed the mitigation system at the real field and test of its efficiency in Busan and Seoul, Korea. In this paper, the results of field test, especially, distributed ICCP are described.

Robot and application of IT skill of construction industry are slow comparatively than another thing industry by the feature. This research proposes progress management and real time information gathering through construction automation and RFID focused on steel structure construction. Building for RTPM system, must consider various variables and surrounding situation in construction field and it is the most important and difficult matter that draw right requirement and grasp relation between this requirements to accomplish one suitable task considering these environment. Therefore, in this study analyzes requirement and target for RTPM system based on scenario that is easy to draw requirement and apply this to use case model. Presented method suggests that represent relation between goals and way that refines goal systematically from requirement of RTPM system. And it could express for visualization through the Way that attaches nonfunctional elements of system with system internal goal.

In line with the rapid economic growth of many countries, fossil fuel energy sources are also rapidly depleting. Therefore, the price is also rising rapidly, so it is necessary to develop new and renewable energy sources such as hydropower, geothermal power, nuclear power, wind power and solar energy to replace fossil fuel energy in the future. In this study, development of rotating concentrator module system, development of rotating module control control system, development of lamp and charge control controller, configuration and prototype production of rotating concentrating solar LED street light system, efficiency of rotating concentrating solar LED street light, and power production. The research was conducted in the order of evaluation of comprehensive performance tests such as consumption and consumption. As a result, the developed high-efficiency rotation-concentrating hybrid solar LED street light module system has a 50% higher light-gathering efficiency than existing products by tracing sunlight by self-developing a rotation-collecting module on existing solar LED street lamps according to the characteristics of Korea's topography. and the power generation was improved by more than 40%.

요즘처럼 웹을 이용하여 저오 검색시 너무나 많은 양의 정보를 수집, 정리, 관리해야 하는 문제에 직면하게 되었다. 또한 인터넷상에는 기존의 텍스트 자료 이외에도 이미지, 사운드, 데이터 베이스 등 우리가 원하는 여러 유형의 자료가 존재한다. 하지만 웹상에서는 텍스트만을 위주로 자료를 검색, 수집, 분류를 한다. 이러한 문제점을 해결하기 위해 XML를 이용하여 정보의 종류에 관계없이 수집할 수 있다. 이 논문에서는 이동 에이전트를 이용한 정보 검색 모형을 제시하고 이때 이동에이전트가 정보의 표현방법으로 XML를 사용한다. 또한 XML의 계층적인 특성을 활용하여 XML 문서의 분류, 병합을 할 수 있다. 따라서 수집된 정보의 정리된 형태로 쉽게 얻을 수 있다.

In this paper, we propose the integrated security management framework supporting the trust for the ubiquitous environments. The proposed framework provides the gathering and analysis of the security related information including the location of mobile device and then dynamically configures the security policy and adopts them. More specially, it supports the authentication and delegation service to support the trusted security management for the ubiquitous networks. This system also provides the visible management tools to give the convenient view for network administrator.

In WDM/SCM-PON system more than thousand signals must be gathered to monitor for operation. We have implemented IEEE STD 1149.1 JTAG serial interface bus to gather and monitor analog signals. Required area is just $5{\times}5mm^2$. Gathering time per one signal is $1.75{\mu}$ second. Performance to gather is better than that defined in SFF-8472.

No organization can survive in today's modern society of information and high technology without internet and/or intranet. International convention industry is one of many high-technology dependent fields today which have started gathering new attention since the new millennium had begun. According to our survey, no professional convention organizer has used so far any type of integrated information system which is the vital source of support of the convention industry. Only the general purpose office softwares have been in use. The main purpose of this study is to design a model for ICIMS(International Convention Information Management System) to manage all the related information of international convention in a systematic and integrated way and to implement its prototype. International convention system in general had been analyzed to enhance the level of accuracy of the model for ICIMS. A simulation of an international conference was conducted to test the core module of the ICIMS model.
