The economy of Korea has grown up significantly in its scale. It has, therefore, become imperative to develop countermeasures to prevent work related injuries and occupational illnesses resultining from haza-rdous working conditions and handling harmful substances. A lot of cargo handling accident in port have occurred due to the characteristics of poor working environment, diversity of working place and method, fluctuation of the amount of cargo and handling of heavy, long, harmful and dangerous cargo, etc. According to '91 industrial accident analysis carried out by the ministry of labour, the number of the stevedores injured by cargo handling accident in port were 1, 432 persons (the death accident : 22 per-sons), the amount of industrial accident compensation in port was 6.7 billion won (the amount of economic loss : 33.6 billion won), and the injury occurance rate of the stevedoring industry was higher than that of the whole industry. This paper, therefore, aims to the actual status of the stevedoring industry and to extract the main cau-ses of the accidents related to cargo handling in port through factor analysis using the data of the accide-nts in the whole habour from 1990 to 1992, and to suggest the countermeasures to prevent such accident. The main causes of the accident and countermeasures are found to be as follows through the factor analy-sis : Factor1, factor2, and factor3 related to a defect of human being and management, a defect of state and environment, and an insufficiency of education and law are extracted. The short-term countermeasures to prevent these accidents are 1) to consolidate the safety and health organization in the working spot, 2) to secure a safe condition in working spot before dock work, 3) to strengthen a dock worker's safety educa-tion. The long-term countermeasures are 1) to promote a decasualisation of dock workers, 2) to modernize the cargo working methods through constructing exclusive pier and introducing exclusive cargo handling equipment, 3) to establish a exclusive dock accident prevention organization and the dock workers law. Factor 4, factor5, factor6, and factor7 related to an unfitness, a deficiency of technical knowledge, a nonfu-lfilment of safety measures, and a bad arrangement are extracted. The countermeasures to prevent these accidents are 1) to perform a complete safety inspection of cargo handling equipments and tools and to carry out the dock work according to a working plan, 2) to publish and supply technical safety books, safety instruction book, safety check list, etc., 3) to strengthen the safety patrol at the working spot in habour and to activate a safety fund, 4) to maintain always a clean workshop with the safety consciousness in which the good arragement of the working spot is considered to be the beginning of safety.

The measurement of surface roughness and waviness by means of noncontact method is an important area to be developed for GAC(Geometrical Adaptive Control) system. This paper deal with the design of noncontact in-process measurement system which measures the surface roughness and waviness during cylindrical grinding. This measuring system is simple and the apparatus proposed is composed of a laser unit, photodetector and optical system. During operation, the surface of a workpiece is continuously scanned by a laser beam. This method makes it possible to detect the surface roughness and waviness along the feed direction by control the spot diameter of laser beam. The experimental results show that the presence of chattering, loading and glazing can be detected sensitively along the feed directions.

This study measures the levels of various receiving points for reducing deviations the floor impact sound. According to the results, 63-125Hz band appeals the large deviations. Among the spacial points, the spot of 0.75m from the wall correspond with the average of all spots. The KS stipulates that the receiving point should be off the wall more than 0.5m But obeying the rules, the large deviation appears. So, this study shows that the adequate receiving point is 0.75m from the wall.

For the accurate generation of DEMs, the determination of match quality in adaptive least square matching algorithm is significantly important. Traditionally, only the degree of convergence of a solution matrix in least squares estimation has been considered for the determination of match quality. It is, however, not enough to determine the true match quality. This paper reports two approaches of match quality determination based on adaptive least square correlation : the conventional if-then logic approaches with scene geometry and correlation as additional quality measures; and, the fuzzy logic approaches. Through these, accurate decision of match quality will minimize the number of blunder and maximize the number of exact match. The proposed methods have been tested on JERS and SPOT images and the results show good performance.

In this work, effects of hyper-elastic rubber material properties on the indentation load-deflection curve and subindenter deformation are first examined via [mite element (FE) analyses. An optimal data acquisition spot is selected, which features maximum strain energy density and negligible frictional effect. We then contrive two normalized functions. which map an indentation load vs. deflection curve into a strain energy density vs. first invariant curve. From the strain energy density vs. first invariant curve, we can extract the rubber material properties. This new spherical indentation approach produces the rubber material properties in a manner more effective than the common uniaxial tensile/compression tests. The indentation approach successfully measures the rubber material properties and the corresponding nominal stress.strain curve with an average error less than 3%.

The purpose of this thesis is to lay groundwork for the development of emergency care system in metropolitan area. It compares the performance and outcome of the current system with foreign counterparts and investigates the changing aspects of future medical environment. Emergency medical system can be divided into two parts of both pre-hospital care, which refers to the emergency measures taken before arriving at a hospital, and hospital care that is given within a hospital. Pre-hospital care includes on-the-spot expedients, information system and delivery system, whereas hospital care is related to the classification and specialization of medical care facilities. This research focuses on the evaluation of the performance of a rescue party, which is part of pre-historical care system. As a result, it provides valuable material for the development of the emergency medical system in Seoul.

도시적 토지이용공간의 절대부족 등 도시의 제반문제들을 해결하기 위해 세계 각국뿐만 아니라 우리나라에서도 지속적으로 지하공간의 이용범위를 확대하고 있는 실정이다. 그러나 지하공간의 활용은 수많은 잠재력과 동시에 문제점들을 내포하고 있는 동전의 양면성을 지니고 있다. 특히, 9 11 테러 이후 발생되는 뉴테러리즘은 대중교통수단이나 다중이용시설 등에 대한 이른바, 'soft target'으로 변화되는 추세를 보이고 있다. 그 결과, 대표적인 예로 2003년 대구지하철 화재사고, 2005년 영국 런던지하철 연쇄폭탄테러사건 등 부정적 결과를 낳게 되었다. 이렇게 지하공간에 대한 안전사고 우려에도 불구하고 지하공간의 활용은 불가피한 선택이 될 수밖에 없으며 빠른 속도로 늘어나고 있는 실정이다. 그러나 우리나라는 아직까지 지하공간의 종합적인 테러대응책은 크게 미흡하여 보완대책마련이 시급한 실정이다. 따라서 본 연구는 테러관련 사건 중 국내 외의 지하철에서 발생된 피해사례를 통해 효율적인 대책을 제시하는데 그 목적이 있다. 테러발생으로 인해 피해를 최소화하기 위한 테러대응책을 요약하면 다음과 같다. 첫째, 테러발생으로 인한 화재나 유독가스로부터 지하공간 이용자들의 인명구조를 위한 방호 장비가 확보되어야 하고 둘째, 테러발생 시 신속한 행동을 통해 피해를 최소화하기 위한 현장대응 관리와 체계적인 교육훈련이 확립되어야 하며 셋째, 테러발생 시 불특정다수가 신속히 대피할 수 있는 지하공간의 대피로가 마련되어져야 하고 넷째, 체계적 전방위적인 대응을 위해 유관기관간의 네트워크망 형성이 필요하다. 마지막으로 사후수습을 위해서 사고피해자 및 유가족들에 대한 정부당국의 신속하고 전문적 서비스를 통한 피해대책이 마련되어져야 할 것이다.

The objective of this study is to estimate the level of exposure of traffic-related air pollutants (TRAPs) on the pedestrians in Seoul area. The road network's link-based pollutant emission was calculated by using a set of mobile source emission factor package and associated activity information. The population information, which is the number of pedestrian, was analyzed in conjunction with the link-based traffic emissions in order to quantify exposure level by selected 23 spots. We proposed the Exposure Intensity, which is defined by the amount of traffic emission and the population, to quantify the probability of exposure of pedestrian. Link-based traffic NOx and PM emissions vary by up to four times depending on the location of each spot. The Hot-spots is estimated to be around 1.8 times higher Exposure Intensity than the average of the 23 selected spots. The information of Exposure Intensity of each spot allows us to develop localized policies for air quality and health. Even in the same area, the Exposure Intensity over time also shows a large fluctuation, which gives suggestions for establishing site-specific counter-measures.
