In order to evaluate the confounding factors of neurobehavioral tests and the neurobehavioral effects in the workers exposed to organic solvents, NCTB was carried out on 100 workers. 46 workers had never been exposed to neurotoxic substances, and the others were being exposed to the solvents, mainly toluene. Simple reaction time, digit symbol, Santa Ana dexterity test and persuit aiming were different with age in non exposure group. Simple reaction time was carried out well in males, and digit symbol and persuit aiming were in females. There was no difference at educational level when the subject was educated over 12 years. Santa Ana dexterity and Benton visual test differed according to exposure level to toluene, however simple reaction time didn't. The acute neurotoxic effect was not excluded in this study. But, NCTB could be used to evaluate and prevent neurobehavioral changes in workers exposed to neurotoxic solvents in Korea.

본 연구에서는 현재 고시, 운영되고 있는 섬진강 수계의 하천유지유량을 수량과 수질, 수생태계의 상태를 근거로 평가하여 그 적정성을 살펴보았다. 유량평가는 주요 댐 건설전 유량자료가 남아있으며, 섬진강 본류 최 하류에 위치하여 섬진강 유량관리의 핵심이 되는 구례군(송정리) 지점의 유량을 바탕으로 평가하였다. 수질과 수생태계 상황은 최근 20년간 측정된 자료를 바탕으로 확인하고 하천유지유량 달성정도는 다른 수계 주요 지점의 하천유지유량 달성도와 비교하였다. 평가자료를 기반으로 새롭게 산정이 필요한 세 개 하천과 11개 지점에 대해 하천유지유량을 재산정하였다. 현재 허가된 하천수 사용량을 기반으로 갈수기 하천유지유량 부족량 공급을 위한 필요수량을 예측해 물관리 업무에 참고가 가능하도록 제시하였다. In this study, the appropriateness of the current publicly announced and managed instream flow in the Seomjingang River watershed was evaluated based on the water quantity, water quality, and state of the aquatic ecosystem. The stream flow was evaluated based on the observed water flow rate at the Gurye-gun (Songjeong-ri) station that is the main point of the Seomjingang River flow management and located at the lowest downstream of the main stream of the Seomjingang River. Another important reason for choosing this station was that observational data from before the construction of the major dam to the present day were available. The water quality and aquatic ecosystem conditions were reviewed based on the data measured over the past 20 years, and the achievement ratio of instream flow was compared with that of stations in the other major river systems. Based on the evaluation result, the instream flow was re-estimated for the 11 important stations of the Seomjingang River and its two branches. Based on the currently permitted water use of the Seomjingang River, the amount of water required to supply for the instream flow deficit during dry seasons was predicted and presented as a reference for water management work.

본 연구의 목적은 도시계획이나 하천사업에 있어서 홍수방어 대안의 우선순위를 결정하는 기법을 선정하는 것이다. 도시계획이나 하천사업에는 다양한 대안과 평가기준을 통해 방향이 결정되므로 이를 반영할 수 있는 의사결정기법이 필요하다. 따라서 의사결정의 방법론과 특징을 조사, 분석하였으며 다기준 의사결정방법 중 PROMETHEE, ELECTRE 방법 및 엔트로피 척도를 이용하는 방법을 적용하였다. 동일한 조건에서 순서우위 방법인 PROMETHEE와 ELECTRE는 매우 유사한 결과를 제시하였으나, 엔트로피 척도에 의한 방법은 평가기준과 대안간의 비례, 반비례 관계를 반영하지 못하는 점으로 인해 직접 적용을 위한 개선이 필요한 것으로 나타났다. The purpose of this study is to select techniques for prioritizing flood defense alternatives in urban planning and river projects. Urban planning and river projects should be determined through various alternatives and evaluation criteria, so appropriate decision making methodology will be needed. Therefore, decision making methodologies and its characteristics were investigated. With a result, PROMETHEE, ELECTRE and Entropy measure among Multi-Criteria Decision Making method were applied. The outranking method(PROMETHEE and ELECTRE) presented similar result however Entropy measure need to improvement because of conflict priority with outranking method which is originated from ignorance of proportion relationship.

본 논문에서는 기존의 교통 상황 검지 장비들이 가지고 있는 문제점들을 해결하기 위해 실제 통행속도 데이터의 해당 도로 속성들을 이용하여 데이터 마이닝을 통한 합리적인 오차 범위 내에서의 실시간 교통 정보 예측 알고리즘을 제안한다. 본 논문에서 제안하는 알고리즘은 데이터 마이닝의 분석 기법중 하나인 신경망(Neural Network)분석을 통하여 통행 속도 예측 근사 모델을 개발하는 것이며, 기존의 교통 상황 판단 알고리즘과의 결과 비교를 통해 비용 절감 효과와 속도 정보가 없는 도로까지의 합리적인 통행 속도 예측, 그리고 Off line상에서의 시간대별 교통 정보 제공이 가능함을 보인다.

Existing Statistical approaches used for the analysis of Vehicle Package Factors are overly weighted toward studies on the Quantitative Analysis about either Characteristics of consumers` behaviors or Sensibility Evaluations. In this study, Differences in characteristics of Human are definitely divided into two aspects (Physical Factors on constraints of movement - `Passively selecting area` and Psychological Factors -`Actively selecting area`) This study is also tried to bring forth evidence for Quantitative Method dissolved Outputs selected into these two aspects into Information Processing System. This approach is very useful for replacing an indefinite ideological view with a definite phenomenon in the extraction and improvement of Factors had an important effect in Sensibility Evaluations ;(the last step of Perception, Cognition and Motion); we will get a good approach to implement for a comprehensive management.
