Procedures to establish well-balanced development and effectiveness of environmental impact assessment need include various stakeholder's participation in writing and reviewing document of environmental impact assessment, collecting public opinion, and post monitoring. Accordingly, to encourage effective and efficient collection of resident's opinion analyze present conditions and problems and suggest institutional and politic alternative proposals of it. This study resulted in following conclusions. In institutional aspects, (1) Proposal for drafting document of environmental impact assessment (2) Composition of committee for collecting and regulating stakeholder's opinion (3) Width of civil participation scale. In politic aspects, (1) Use of local community (2) Guide of local information from local society and environmental specialist (3) Understandable document and data of environmental impact assessment (4) Strength of roles and duties of local government.

The number of satellite under operation is being on the increase, however, because the number of operator is limited the reliable control system is necessary for stable mission operation. Especially it is necessary that error event indication such as colour or sound should be displayed with high reliability for intuitional monitoring. The limit range of KOBAS2 provides realistic value that is defined with in-orbit value and related document. It makes it possible for operator to monitor a number of telemetry data easily through single screen system instead of monitoring each mnemonics. The development and operation experience of KOBAS2 will contribute to the development of the evolved automatic telemetry monitoring system for future mission.

In manufacturing of welded parts which require a proof on acceptance close observation of the process is mandatory. The manufacturer is obliged to document the welding process. An approach for monitoring and recording the process of laser beam welding combining theoretical knowledge, process monitoring and welding experience will be presented. The range of application of a device for co-axial process monitoring was extended up to 20 mm sheet thickness welded in one pass at beam powers of up to 20 kW. Crucial features of the process which refer to the formation of failures were observed. The results presented give rise to the general applicability of the approach for process monitoring and recording as well as failure management.

In this paper, we present a framework that is easy to develop, modify, maintain and extend a control and monitoring software for any kinds of instruments. The presented framework is composed of three XML documents (IID, MAP, and CMIML) and two tools (Virtual Instrument Wizard, Generator). Interface information about behaviors and states of instruments is written on IID. Mapping information between the interface information in IID and API of a real instrument driver is written on MAP. Finally information about control and monitoring software is written on CMIML. IID, MAP and CMIML are written with XML format to provide common usage and platform independence of the suggested framework. VI Wizard generates CMIML (platform independent intermediate document) using IID and existing CMIML, and Generator generates source code of a control and monitoring software (platform dependent code) automatically using CMIML and MAP. The suggested framework that automatically generates control and monitoring software based on GUI provides easy development and maintenance. Also, reusability can be increased by reusing platform independent software description documents.

The systems of the nuclear power plant are designed based on the User Requirement Document, and Korea Hydro & Nuclear Power Co. (KHNP) implements preventive maintenance activities to keep the specific design function of the system consistently. To monitor the preventive maintenance effectiveness, KHNP has also developed maintenance effectiveness monitoring (MR) program based on NUMARC 93-01 since 2003, and has implemented the program in all operating plants. Recently, KHNP has upgraded MR programs by reflecting implementing experiences ; reestablishing the performance monitoring level, improving analysis for standby function and performance criteria for passive components, reestablishing the availability performance criteria and the performance criteria for the same type of components. These upgraded MR programs will contribute to enhance safety and improve equipment reliability through monitoring maintenance effectiveness.

Since most of the conventional web servers have been designed to Provide the general purpose and user's convenience as the primary goal, there is an overhead to apply them to the embedded system for remote monitoring and controlling the operation status of the Internet appliance. To cope with this overhead, an embedded Linux web server Is suggested in this paper The basic concept is to provide miniaturization and extendability by simplifying the requirements of web server as the services to the requests of web document for the user's menu and the execution of CGI Program for monitoring and controling the Internet appliance, and satisfying only the indispensable requirements of HTTP which are necessary for the interface with the conventional web browsers. For the evaluation of its feasibility, each module has been implemented on Linux environment, and tested with the MS Explorer 6.0.

Oil spills cause huge material damage. Oil and oil products spills may occur at any stage of the offshore oil production and transportation cycle. Therefore taking into account the current trends of oil production, the task of creating a system for shelf and tank fleet monitoring becomes very crucial today. This document describes the technology being implemented to improve oil spill monitoring and surveillance, to ensure SAR data fast acquisition and processing and to develop geographic information systems in support of spill response decision making. The results of technology implementation are also presented below.

Environmental risk assessment of cadmium compounds was conducted using national monitoring data of aquatic and terrestrial compartments of local area. Aquatic and terrestrial toxicities of cadmium compounds on algae, daphnid, fish, earthworm, springtails and other species were evaluated. The toxicity data evaluated in this study were mainly from ECOTOX database provided by US EPA. Assessment factors were determined according to the EU technical guidance document and/or OECD proposal. Predicted no effect concentration (PNEC) values of aquatic and terrestrial toxicity were 25$\mu\textrm{g}$/L and 0.2 mg/kg, respectively and they were compared with cadmium exposure data of several local areas, which were used as Predicted exposure concentration(PEC) values. Most of the local area were found to be not risky. However, the risk values (PEC/NEC) of some metropolitan areas were greater than 1 when the most conservative PNEC value was applied.

웹 서비스 어플리케이션 기반 모니터링 시스템에서 빈번히 발생되는 데이터 구조 변경에 따른 코드 재생산에 확장성 및 오류 복구능력 향상을 위하여 DTD(Document Type Definition)자동 생성 기법을 이용한 모니터링 시스템 설계방법을 제안하였다. 제안한 DTD자동 생성 기법은 센서 데이터 구조가 수정되어도 서버 측에서 동적 서버사이드 스크립트(Dynamic Server-side Script)로 DTD정보를 자동으로 생성해 주기 때문에 데이터 손실과 오류에 대한 능동적인 대처가 가능하며, AJAX(Asynchronous JavaScript and XML)를 이용한 XML데이터 파싱(Parsing)을 구성하여 대단위 데이터 전송이나 다양한 모니터링 시스템 분야에 데이터 손실이나 손상 확인 등의 예외처리 및 데이터 구조의 확장과 축소가 용이하였다. 제안된 시스템은 일시적인 데이터 깨짐 상황에서 정상화 복구에 필요한 평균시간이 기존의 XML을 이용한 방법보다 약 44.8ms감소되어 오류 복구처리 속도가 향상됨을 알 수 있었다.

Buckling failure is a typical slope instability mode that should be paid more attention to. It is difficult to provide systematic guidance for the monitoring and management of such slopes due to unclear mechanism. Here we examine buckling failure as the potential instability mode for a slope above a railway tunnel in southwest China. A comprehensive model test system was developed that can be used to conduct buckling failure experiments. The displacement, stress, and strain of the slope were monitored to document the evolution of buckling failure during the experiment. Monitoring data reveal the deformation and stress characteristics of the slope with different slipping mass thicknesses and under different top loads. The test results show that the slipping mass is the main subject of the top load and is the key object of monitoring. Displacement and stress precede buckling failure, so maybe useful predictors of impending failure. However, the response of the stress variation is earlier than displacement variation during the failure process. It is also necessary to monitor the bedrock near the slip face because its stress evolution plays an important role in the early prediction of instability. The position near the slope foot is most prone to buckling failure, so it should be closely monitored.
