The port, differently from general working place, is a closed area to execute security, customs, and quarantine procedures. The loading and unloading is being done differently by cargoes, ships, berths, and equipments. To load and unload a lot of equipments and different types of labor are required, in which work flow is very complicated. As above mentioned the port is very unique and deteriorated working place including danger. Now frequency of cargo handling accidents in port is highest for the second time among all industries. The purpose of this study is to propose ways to analyze and establish the preventive measure for cargo handling accidents in port. We have collected 45 accidents happened at Incheon Port during the period from 2007 to 2009. And the result of analysis, we proposed the new safety management system and safety education to reduce cargo handling accidents and to promote the quality of cargo handling in Incheon Port. Within the framework of effective safety management of cargo handling in port, this study will help to revise and establish system, education, and standard working manual with respect to the port loading and unloading system.

Human sensibility ergonomics is the technique that qualities man's sensibility, measures and evaluates it Quantitatively and makes man's life comfortable, safe and delightful by applying it to products or environmental projects. This study consider the sensibility factor of Sasang constitutional medicine, five elemental properties, and Biorhythm in terms of human sensibility ergonomics. And this study measure reaction-time dependent on a temperament or a state and evaluate the differences of reaction-times objectively with the comparison and analysis using the ANOVA. We can harness it for job design.

Fire and smoke can from a small ignition source develop rapidly. Active systems in combination with Passive Fire Protection measures will offer highest safety standards to the building's developers and occupants. Nevertheless, the fire growth is very unpredictable and it is therefore essential at the planning stage that tested solutions are well selected according to National codes and later on installed by qualified contractors to ensure optimum performance. This demonstrates that Passive Fire Protection as safety measure cannot be neglected. Recent fire cases all over the world still proof that fire can develop any time and any where even in countries of high safety standards.

In the future, all kinds condition of industrial safety is a primary need in all advanced countries in which workplace safety is an issue. Furthermore, the increasing complexity of production systems and the rapidity of technological innovation have consolidated the recognition of the strategic value of safety, alongside the traditional competitive factors such as quality, costs, delivery time and flexibility, In this paper, the some critical issues of changes and counter-plan in an adequate safety management were identified by above considerations as follows： needs of systematic identification and analysis of safety factors； requirements to define priorities and budgeting to support the decision-making process; and needs of audit activities and indicators which measure company performance in terms of safety improvements, and so on.

안전지식 함양, 안전기능 체득, 안전태도 향상을 목표로 하는 안전교육은 별다른 제한 없이 효율적으로 사용될 수 있는 중요한 안전대책일 뿐만 아니라 재해를 감소시키기 위한 수단 중에 제일 큰 우선도를 갖는다. 그러나 건설현장에서의 안전교육은 매우 형식에 치우쳐 교육을 위한 교육일 뿐이며 근로자들에게 안전교육 시간은 지루하고 따분한 시간일 뿐이다. 이러한 이유는 자기와 상관없는 교육내용과 개인적 특성을 무시한 일괄교육에서 기인하며 이는 더 이상 근로자의 자발적 참여를 유도하지 못한다. 따라서 건설근로자들의 개인적 특성에 맞는 다양한 안전교육 모델 개발이 필요하다. 이에 본 연구는 건설근로자의 개인적 특성에 맞는 안전교육 모델을 구축하기 위해 건설현장에서 종사하는 근로자를 대상으로 설문조사와 통계분석을 실시하여 개인적 특성에 맞는 안전교육 모델을 제시하였다.

Surrogate safety measure(SSM)를 이용하여 도로상의 위험을 측정하는 방식은 사고의 직접적인 원인과 연관된 차량의 거동을 분석 대상으로 한다는 장점을 가지고 있으나, 한 지점에 국한된 정보를 이용하기 때문에 위험을 연속적으로 분석하는 데에 제약이 있다. 이러한 한계를 극복하기 위해 본 연구에서는 RTK-DGPS를 이용하여 차량들의 궤적을 얻는 방안을 제시하고, 이를 통해 time-to-collision(TTC), deceleration rate to avoid collision(DRAC), acceleration noise(AN) 등의 SSM을 산출하는 데에 필요한 문제들을 고려한 방법론을 설정하였다. 또한 본 연구에서는 검토된 방법론을 이용하여 운전 중 발생하는 다양한 차량거동 변화를 관찰하기 위하여 영동고속도로 북수원IC-군포IC 구간을 대상으로 실험을 수행한 결과를 제시하였다. 그 결과 궤적 기반 SSM 지표값이 다양한 주행 상황에서의 위험성을 합리적으로 설명할 수 있음을 확인하였다. 본 연구는 향후 다양한 구간특성 및 운전자 특성에 따른 위험상황을 설명하는 연구를 수행하고, 위험구간 감지 및 위험한 운전행태의 감지를 통한 사고예방에 활용될 수 있을 것으로 판단되며, 이를 통하여 위험도로 개선 및 교통사고 줄이기 사업을 효율적으로 추진하는 데에 기여할 수 있을 것이다.

Purpose: This study was aimed to develop a WBI(Web Based Instruction) program on safety for 6th grades of elementary school students and to test the effects of it. Method: The web site is http://www.safeschool.co.kr. The effect of it was tested from Mar 24, to Apr 30, 2003. The subjects were 150 students. Data were analyzed with descriptive statistics, and $x^2$ test, t-test, and repeated measure ANOVA. Result: In the knowledge of the safety precaution, the preliminary test was mean 17.8, immediate post-test was mean 20.9 and 4 weeks post-test was mean 20.9, there were significant differences statistically among three points of time. In the attitude of the safety precaution, the preliminary test was mean 75.1, the immediate post-test was mean 80.8 and 4 weeks post-test was mean 80.4, which showed significant difference statistically among three points of time. For the motive of learning to the safety precaution, it was significantly higher statistically in the WBI. As a result, the WBI group had totally longer effects on knowledge, attitude and motivation of the safety accident prevention than the textbook-based instruction. Conclusion: WBI program be used in each class to provide more effective safety instruction.

This paper is to study a technique to detect the real-time route aberrance on the passage route using bumper area of the ship domain theory. In order to evaluate the risk of route aberrance, a quarter line was created between the center line and the outer line, and a passage route with the image line outside the outer line was designed. It calculated the real-time route aberrance with the vessel bumper area to measure the risk level on the passage route. The route aberrance using overlap bumper area was simulated through three kinds of scenario vessel at the designed passage route. In this paper, we proposed Ratio to Aberrance Risk as one of the evaluation parameter to detect the route aberrance risk at each sector in the passage route and to give the evaluation criteria of 5 levels for seafarer's navigation safety. The purpose of this work is to provide the information of the route aberrance to seafarer automatically, to make it possible to prevent the human errors of seafarer on the high risk aberrance route. As the real-time risk of route aberrance on the passage route is automatically evaluated, it was well thought that seafarer can have only a little workload in order to know the risk of route aberrance at early-time. Following the further development of this work, the techniques for detecting the real-time route aberrance will be able to use the unmanned vessel.

Viscosity agents were added to water to improve extinguishing performance of low pressure water mist suppression system on wood cribs fire, and a small scale wood cribs fire experiment was conducted to measure the extinguishing performance. CMC and agar were used for viscosity agent and as the amount of viscosity agent enlarges, it showed the increase of the viscosity of aqueous solution and the decrease of the fluidity. On wood cribs fire experiment, the extinguishing efficiency was improved with supplemental viscosity agent as it enhanced the adhesive time of aqueous solution on the wood, and therefore expanded the contact time of fire surface. The surface tension of aqueous solution was decreased with the addition of agar which to be assumed as an increase factor of extinguishing efficiency. By the extinguishing experimental result, the most effective extinguishing agent was CMC 0.6 wt.%, with the flame suppression time and the extinguishing time were reduced by 70s and 93s respectively at this concentration.

부산항 'A' 터미널에서 발생한 지난 3년간의 사고 데이터를 분석하여 어떤 장비가 가장 많이 사고를 발생하였고 어떤 위험점이 가장 높은지를 위험성 평가기법으로 알아보고, 이러한 사고를 미연에 방지하기 위한 방안을 보우타이 기법을 활용하여 제시하고자 한다. 실증자료를 분석한 결과 터미널 내의 이동장비 중 야드 트랙터의 충돌사고가 가장 높은 것으로 나타났다. 안전한 부산항을 만들기 위하여 우리는 가장 먼저 야드 트랙터의 충돌사고 예방법 (Control measure)과 사고 발생 시 대처방안 (Recovery measure)을 철저히 준비하여 사고를 미연에 방지하여야 할 것이다. 본 연구의 결과는 관련 실무에 다양한 시사점을 제공하였다.
