This study presents a R&D performance monitoring system (RDMS) that is applicable for managing nuclear program in KAERI. The prime goal of RDMS is to furnish project manager with reliable and accurate information on status of progress, performance and resource allocation, and attain traceability and visibility of project implementation for effective project management. In this study, the work breakdown structure (WBS) as the governing factor for integration of scope, schedule, resource data was derived, and the above parameters were loaded personal computer. A RDMS is comprised of about 12,000 R&D activities of the 16 goverment-led projects. The Primavera software was used to monitor the progress, evaluate the performance and analyze the resource distribution to activities.

Significant progress has been made recently in detection of highly sensitive volatile organic compounds (VOCs) using chemical sensors. Combined with the progress in design of micro sensors array and electronic nose systems, these advances enable new applications for detection of extremely low concentrations of breath-related VOCs. State of the art detection technology in turn enables commercial sensor systems for health care applications, with high detection sensitivity and small size, weight and power consumption characteristics. We have been developing an intelligent electronic nose system for detection of VOCs for healthcare breath analysis applications. This paper reviews our contribution to monitoring of respiratory diseases and to diabetic monitoring using an intelligent electronic nose system for detection of low concentration VOCs using breath analysis techniques.

In this study, we measure and analyzed variation of EEG signal by anesthesiologist progress step. In an experiment, the EEG signal was acquired and analyzed as 5 steps(prior surgical operation, during induction, surgical operation, awakening, posterior surgical operation). As a result, we confirm the anesthesiologist progress phase, concluded the possibility of anesthesia depth because using SEF and MF, and Delta ratio confirmed that can presume operating patient's consciousness state.

결론적으로 위성에 의한 강우관측은 지금은 지구의 거의 대부분 지역에서 관측 및 모니터링과 더불어 강우를 이해하는 능력에 커다란 기여를 하고 있다. 특히 1997년 11월 TRMM의 등장으로 강우의 연직분포 및 정량적 관측이 이루어지므로서 국내에서도 위성강우의 활용연구가 급진전할 것으로 기대된다. 또한 위성강우자료를 이용한 농업 및 수자원분야에서의 연구도 기대된다. 위성강우자료를 농업/수자원 분야에 적용하기 위해서는 먼저 자료간의 결합시에 발생되는 규모(scale)와 해상도(resolution) 문제를 다루는 평가연구가 요구된다. 규모문제는 주어진 연구에 가장 적절한 구역의 개수에 대한 불확실성 때문에 발생되며, 해상도 문제는 해당자료를 저해상으로 결합하여 분석하게 되면 기대치 이상의 정보손실을 야기시키기 때문이다. 이와 같은 의문점이 어느 정도 구명된다면 위성강우자료를 이용한 연계연구는 무궁무진하다고 말할 수 있다. 예를 들면 농업분야에서는 위성강우에 의한 격자기반(grid-based)의 토양수분 및 지하수위 변화, 농경지 침수지역 예측 등에, 수자원분야에서는 공간강우-유출해석에 의한 홍수예 · 경보시스템의 향상, 도시지역 홍수범람지역의 예측 등에 활용할 수 있다.

Bioventing is commonly used for petroleum hydrocarbon (PHC) spills. This process provides better subsurface oxygenation, thus stimulating degradation by indigenous microorganisms. Therefore soil vapor monitoring points (VMPs) are extremely important in determining the potential effectiveness of bioventing and in long-term monitoring of bioventing progress. In this study in-situ soil gas monitoring well (GMW) was developed and presented the pilot test results which recover the contaminated site by bioventing method. The result of application was successful and it was expected that GMW developed could be applied to the evaluation procedure of bioventing effectiveness and long-term remediation potential.

The purpose of this research is to present a practical method for efficiently monitoring a reliability growth process using AMSAA(Army Materiel Systems Analysis Activity) reliability growth model. The presented method is viable for identifying failure modes, incorporating design changes and monitoring reliability progress on an on-going basis during the early stages of a product development program. According to the Application Guide for EN 50126(RAM part for Rolling Stock), reliability growth monitoring is essential part of the main tasks of design phase in RAM growth monitoring. Implementation of reliability growth management program will provide very useful information on concept selection, product/process reliability, and cost effectiveness without too much time, money and engineering effort being spent on the development of failure suspect parts.

교량 상시계측시스템을 이용하여 교량을 감지할 경우 지속적인 교량의 거동이력을 확인할 수 있어 손상의 진행을 관리자가 손쉽게 확인할 수 있으며, 지진이나 홍수와 같은 대규모의 재난상황이 발생할 경우 교량의 상태변화를 정량적으로 파악하여 교량 통제 및 통행제한 등 적절한 사전 조치 등 취할 수 있다. 또한 보수 및 보강 등의 교량 성능향상 작업시점을 적절하게 판단할 수 있어 생애주기를 통한 교량 유지관리 비용을 절감할 수 있다. 교량 상시계측시스템에 적용되고 있는 다양한 계측시스템의 계측항목별 관리 기준치 설정방법 중 범용 유한요소 해석프로그램을 이용하여 교량의 관리기준치를 설정하는 방법을 분석하고 강상자형교에 대한 계측항목별 관리기준을 설정하여 유한요소 해석프로그램을 통한 강상자형교 상시계측시스템 계측항목별 관리기준치 설정의 기준을 제시하였다.

Concrete is an inhomogeneous material consisting of larger aggregates and sand embedded in a cement paste matrix. In this study, an acoustic emission technique has been used to clarify the microscope failure mechanisms of concrete under three point bending test. AE source location has also been done to monitor the activities of internal damage and the progress of microscopic failure path during the loading. The relationship between AE characteristic and microscopic and microscopic failure mechanism is discussed.

Compared to other variables being considered in therapeutics, patient compliance has long been given minor attention although it affects every aspect of medical care; Limited methodology of compliance measurement, in particular, has hampered major progress in research, and pre-conceptions have been reiterated. However, there is a recent surge in interest derived from new data revealed by reliable methods, i.g. continuous medication (compliance) monitoring. The visualization of dynamics in drug regimen compliance over time offers unique opportunities, both to scientific drug evaluation and therapeutics in medical practice. New perspectives related to the descriptive and explanatory side of the problem are outlined by giving examples from various therapeutic fields.
