The implementation of IF group delay equalizer and its performance are presented for radio relay system applications, and measured results are in good agreement with the simulated ones based upon analytical formulations. For waveguide filter of 40㎒ channel spacing, equalized delay accuracy of about +/- 2.0nsec can be obtained only by constructing 4 stage delay circuits, which provides good performance in system BER curves compared with no filter case, and the difference is less than 1.0㏈ at $10^{-12}$ BER. So this scheme with simple hardware design can be used for correcting the distorted group delays mainly caused by wavegiude filters. To evaluate the designed group delay equalizer, various simulated and experimental results are shown here in conjunction with STM-1 signal of co-channel 64-QAM digital radio relay system.

The purpose of this study is to develop an in-service teacher training program for professional development in environmental education. In order to achieve the goal, the in- service teacher training program for professional development in environmental education development / implement team is formed to deal with the development and the implementation of the program. The team is composed of environmental education professionals and environmental education teachers. After the development of the program, 20 teachers were selected to implement the program. Then, through various researches such as interview, monitoring, and survey, the evaluation of the program was done. After the evaluation, the feedback on the program was collected in order to apply the final adjustments and changes to the developed training program for professional development in environmental education. The training program is designed to include the wide range of theories and real life cases. It focuses on certain topic, and is implemented through workshop type training method to increase the participation rate. The major motive of the participants was to develop their professionality in environmental education. Based on the analysis of the training program and the workshop, 69.1% of the program is focused on the environmental education/learning theory, and 71.4% is focused on the environmental education teaching method. The environmental education teaching method is focused on the real life teaching method that could be used in many schools. However, the parts on environmental education philosophy, psychology, and evaluation was not included as a part of the program. Also, the evaluation method of the students learning the environmental education was not introduced as a part of the program as well. It is due to the limited time frame of the training program, as well as its focus on the training method of environmental program. Based on the analysis of the evaluation results obtained through monitoring, the training program for professional development in environmental education is successful in terms of focusing the goal of the program around the environmental education/learning theory and environmental education teaching method, which was the motive of the participants. However, the effectiveness of the program differed from participants to participants based on their majors in environmental education, and it did not last long enough. The future training program for professional development in environmental education should consider the backgrounds of the program participants to have various programs prepared for various groups of people. We suggest that the results of this developed program will be applied to "environmental education teacher licence training" in the future.

개발사업의 부정적인 영향을 감소시킬 수 있는 저감방안의 실효성을 높이기 위해서는 이행률을 높이는 것이 필수적이다. 환경영향평가에서 자연생태환경 동물상 분야의 경우 저감방안에 대한 실효성 문제가 꾸준히 제기되고 있음에도 불구하고 현재 진행되고 있는 개발사업의 이행평가 연구는 미흡한 실정이다. 따라서 본 연구는 환경영향평가사업의 대표적인 유형인 도시 및 도로의 개발사업을 대상으로 자연생태환경 동물상 분야의 저감방안 이행률을 평가하고, 각 저감방안별 이행률 차이가 발생하는 원인에 대해 파악하고자 하였다. 도시 및 도로개발사업 저감방안 이행률은 각 56.0%와 64.4%로 낮게 나타났다. 사후 모니터링은 모든 사업유형에서 이행률이 가장 높게 나타났으나, 서식지 조성과 사고예방 저감방안은 낮게 나타났다. 또한, 저감방안 이행률은 보고서 내 기재된 저감방안 내용이 구체적일 때 높음을 알 수 있었다. 본 연구를 통해 환경영향평가 자연생태환경 동물상 분야 저감방안의 이행률을 높이기 위해서는 평가서 작성 시 대상지의 환경적, 지리적 특성을 구체적으로 반영할 필요가 있으며, 실제로 이행할 수 있도록 상세하게 서술할 필요가 있음을 알 수 있었다. 더 나아가 자연환경에 부정적인 영향을 감소시키기 위해 도입된 환경영향평가 제도의 실효성을 증진하기 위한 기초 근거로서 본 연구가 활용될 수 있을 것으로 판단된다.

This study considers the implementation issues of the inter-vehicle communication system for the vehicle platoon experiments via a testbed. The testbed, which consists of three scale vehicles and one RCS(remote control station), is developed as a tool for functions evaluation between simulation studies and full-sized vehicle researches in the previous study. The cooperative communication of the vehicle-to-vehicle or the vehicle-to-roadside plays a key role for keeping the relative spacing of vehicles small in a vehicle platoon. The static platoon control, where the number of vehicles remains constant, is sufficient for the information to be transmitted in the suitably fixed interval, while the dynamic platoon control such as merge or split requires more flexible network architecture for the dynamical coordination of the communication sequence. In this study, the wireless communication device and the reliable protocol of the flexible network architecture are implemented for our testbed, using the low-cost, ISM band transceiver and the 8-bit microcontroller.

This paper presents the VLSI implementation of RS(reed-solomon) decoder using the Modified Euclidean Algorithm(hereafter MEA) for DVD(Digital Versatile Disc) and CD(Compact Disc). The decoder has a capability of correcting 8-error or 16-erasure for DVD and 2-error or 4-erasure for CD. The technique of polynomial evaluation is introduced to realize syndrome calculation and a polynomial expansion circuit is developed to calculate the Forney syndrome polynomial and the erasure locator polynomial. Due to the property of our system with buffer memory, the MEA architecture can have a recursive structure which the number of basic operating cells can be reduced to one. We also proposed five criteria to determine an uncorrectable codeword in using the MEA. The overall architecture is a simple and regular and has a 4-stage pipelined structure.

This research presents a prototype development and implementation of Decision Support System (DSS) for integrated river basin water management for the flood control. The DSS consists of Relational Database Management System, Hydrologic Data Monitoring System, Spatial Analysis Module, Spatial and Temporal Analysis for Rainfall Event Tool, Flood Forecasting Module, Real-Time Operation of Multi Reservoir System, and Dialog Module with Graphical User Interface and Graphic Display Systems. The developed DSS provides an automated process of alternative evaluation and selection within a flexible, fully integrated, interactive, centered relational database management system in a user-friendly computer environment. The river basin decision-maker for the flood control should expect that she or he could manage the flood events more effectively by fully grasping the hydrologic situation throughout the basin.

This paper discusses some problems of the TMN-based architecture of integrated network management systems and presents a CORBA-based architecture of distributed network management system with reliability, which maintains location transparency of distributed managed objects and provides an interoperability among heterogeneous networks and systems. In this paper, the proposed distributed management system model has been applied to the TMN based management systems and then considered for qualitative evaluation of system performance. Two different types of implementation models have been proposed: one is a system using a CORBA gateway and the other is a pure CORBA system, which maps all managed objects into CORBA objects. The characteristics of two system model have been compared in the respect of system implementation

This study was designed to analyze the status of government policy on the computerization of health centers throughout the country and to identify the factors affecting a successful implementation of the information system. As expected, age and commitment of health center director, computer budgets, user training, and technical supports from the information specialists were the important factors influencing the successful implementation of the system. Compared with the urban health centers, fewer rural health centers installed the system perhaps due to lack budgets and the urban-oriented system features. Moreover, the systems were unevenly distributed according to the geographic regions. Some strategies for successful dissemination of the systems were also suggested.
