울산항 도선구는 부산항과 더불어 우리나라 도선구 중 도선사가 승선하는 선박이 가장 많은 지역이며, 항로 배치가 단순한 편이지만 항로 주위에 부두가 인접하여 해상교통흐름의 혼잡도가 높은 항만이다. 울산항을 이용하는 선박은 아침저녁 시각대에 집중하여 밀집되어 있고, 지형적으로 길이가 긴 항로와 항로 부근에 인접한 부두, 정박지 등으로 인하여 여러 곳에서의 선박간 교차로 위험이 상존하는 해역이다. 이에 이 해역을 이용하고 있는 도선사의 관점으로 울산항 도선구 현황 및 통항선박의 위험요인에 대하여 조사 분석하였다. 또한 선박운항자의 조선 부담감을 정량화한 환경스트레스 모델을 이용하여 어느 해역에 조선 부담감이 존재하는지를 제시하여 도선사들이 어느 정도의 위험을 안고 도선을 수행하고 있는지 조사분석을 통하여 확인할 수 있었다. 또한, 본 연구를 통하여 대상해역을 통항하는 선박들이 지정항법을 따를 수 없는 원인 분석이 가능하게 되어 향후 대상해역 통항 안전 개선방안 마련이 가능할 것으로 판단한다.

This study aims to draw the factors of support and restriction as children play in the outdoor space through their participation. The 135 students (fifth- and sixth- graders) participated in the research using the mapping method included the daily diagram and the open-ended questionnaire. As the research results, the park, the school yard, the playground and the rest space were emerged as play spaces with high utilization rate. Through the analysis of play spaces based on children's perception, the physical and social-psychological factors are drawn as the factors of support and restriction. Some physical factors such as the location are relevant to social-psychological factors such as the friend and the danger. In conclusion, the physical factors which support or restrict children's activities have to be considered with the socialpsychological factors. And the result from children's experience and perception should be basis of providing appropriate spaces for children who are actual users of play spaces.

It is of great importance for any vessel under way, especially in rough sea, to be maneuvered safely with proper seakeeping performance. In this paper, the author aims to develope a navigational safety evaluation system in rough sea by analyzing ship's with the theory of wave spectrum using random process analysis and the theory of evaluating the seakeeping performance. The scope and the method of this study are as follows ; (1) Modelized typhoon mathematically to represent the sea condition in rough sea. (2) Estimated sea conditions by getting wave spectrum, supposing that the wave by typhoon is fully developed short crest irregular wave. (3) Defined evaluation factor of vessel's seakeeping performance and obtained response amplitude operators thereby. (4) Obtained the response spectrum of factors on seakeeping performance. (5) Defined and obtained evaluation index, dangerousness, relative and maximum dangerousness of factors on seakeeping performance. (6) Analyzed the calculated dangerousness of evaluation index and picked the vertical acceleration out of 7 factors as the presentative factor on seakeeping performance. (7) Carrid out the judgement of danger by obtaining dangerousness value according to steaming hour, course alteration and speed change. By synthesizing the above items, the authors suggests a computer model of navigational safety evaluation system and examined the validity of the model by computer simulation.

Lysozyme protects us from the ever-present danger of bacterial infection and binds to bacterial lipopolysaccharide (LPS) with high affinity. Beyond its role in the activation of protein C, the endothelial cell protein C receptor (EPCR) plays an important role in the cytoprotective pathway. EPCR can be shed from the cell surface, which is mediated by tumor necrosis factor-α converting enzyme (TACE). However, little is known about the effects of lysozyme on EPCR shedding. We investigated this issue by monitoring the effects of lysozyme on phorbol-12-myristate 13-acetate (PMA)-, tumor necrosis factor (TNF)-α-, interleukin (IL)-1βand cecal ligation and puncture (CLP)-mediated EPCR shedding and underlying mechanism. Data demonstrate that lysozyme induced potent inhibition of PMA-, TNF-α-, IL-1β-, and CLP-induced EPCR shedding. Lysozyme also inhibited the expression and activity of PMA-induced TACE in endothelial cells. These results demonstrate the potential of lysozyme as an anti-EPCR shedding reagent against PMA-mediated and CLP-mediated EPCR shedding.

경찰청 교통사고통계자료에 따르면, 어린이 교통사고사망자숫자는 점차 감소추세에 있으나, 여전히 하루평균 약 1명 이상의 어린이가 사망하고 있는 실정이다. 어린이 교통사고의 유형에 있어서도 어린이 사상자의 $60{\sim}70%$ 이상이 보행 중 사고를 당하고 있고, 보행 중 사고의 대부분은 자동차로 인한 도로횡단 중 사고이며, 특히 무단횡단 사고가 많은 부분을 차지하고 있다. 어린이들이 많이 보행하는 학교주변. 집주변 또는 학교와 집사이의 통학로상의 교통 환경이 매우 열악함을 보여주고 있으며, 학교주변 어린이 통학로상의 교통 환경 개선의 필요성이 강하게 대두되고 있는 측면이다. 이에 대하여 정부에서는 1995년 이후로 학교주변 300m 이내를 어린이보호구역으로 지정하여 교통안전시설물을 설치하고 차량속도를 규제하는 등 교통 환경을 개선하여 어린이교통사고 예방에 노력을 기울이고 있다. 어린이보호구역의 지정에 관한 기준을 조사하고 문제점을 분석함으로서 효과적이고 정량적인 어린이보호구역 지정에 관한 방법을 제시하였다. 어린이의 교통행동특성과 어린이교통사고, 어린이보호구역 내의 교통사고 자료를 분석하여 어린이교통사고의 특성을 파악하고, 어린이보호구역 내 교통사고의 위험요인을 도출하여 각 위험요인별 세부항목을 구분하였다. 각각의 세부항목은 교통사고에 영향을 미치는 정도에 따라 위험등급을 부여하고, 이를 종합하여 어린이보호구역의 지정기준에 관한 방법론을 제시하였다.

One hundred plants in 43 families used in Malaysian traditional medicine were screened for tumour promoting activity using two methods, the technique of activation of latent Epstein-Barr Virus (EBV) in Raji cells and the irritation test on mouse ear. Extracts of only eight plants belonging to the Euphorbiaceae were found to possess EBV activation factor and to give a positive irritation test in mouse ear. These plants included Euphorbia tirucalli L., E. splendes, Jatropha podagrica, J. gossypyfolia L., Pedilanihus tithymaloides (L.) Poitt., Croton argyratus Bl., Exocoecaria agallocha L. and Codiaeum variegatum (L.) Bl. Seven of these plants are used internally in Malaysian traditional medicine. As such, they pose potential danger in the promotion of initiated cells of the mucosal tissue towards disease. Further studies are required to assess the epidemiological impact of these plants in the development of disease.

A local manufacturing companyin which low back pain(LBP) complaints were frequently reported was selected, and regularly perfomed lifting tasks were investigated using questionnaires and the 1991 NIOSH lifting guide. Among several processes of manufacture in the company, three processes-forming, heating and packing-were studied, where most of tasks were perfomed through manual materials handling (MMH). Questionnaire surveys showed that anthropometric data such as stature, weight and someatotype did not affect and weight of load influenced significantly the incidence of LBP, and workers who expwrienced LBP was older than the inexperienced. In addition, safety education conducted at the company was found to be ineffective in preventing LBP injuries. Lifting indexes(LI) was ranged from 0.86 to 17.0 with an average of 4.49, which revealed that tasks performing in the selected factory were in danger of LBP, and should be ertonomically redesigned. The critical factor reducing LI was found to be the horizontal component in all three processes, and most of weight of load was heavier than load constant(23kg) of the 1991 NIOSH lifting equation in heating process and packing.

Human, physical damage is happened frequently to consumer's safety accident by product defect on modern industrial society. Accordingly, advanced nation including the United States of America enforce product liability law and is protecting consumer more actively from danger of product defect. Our country(Korea) may enforce product liability law since July, 2002, and if business does not grope effective confrontation way about PL, capital strength weak smaller enterprise and venture business corporation's competitive power may affect much corporation's competitive power enfeeblement and survival. This research supplement based on induction and operating QMS in smaller enterprise essential factor that corporations must equip according to product liability law enforcement. And we present integration quality management system model of Product liability to do so that smaller enterprises may can cope effectively at force of Product liability law.
