The objective of this paper is to aid in basic directions for the countermeasure against marine accidents by using the statistical data of Jeju Coast Guard from 1983 to 2012. Marine accidents of about 600~1,000 vessels was reported in all the waters around South Korea from 2000 to 2008. From 2009, these accidents increased rapidly and reached 1,600~2,000 vessels. Although marine accidents of longline fishing vessels did not show a big change prior to 1993, the number have increased steadily until 2007. This is considered a tendency that appears when longline vessels, using the Port of Sungsanpo as a base and operating in fishing grounds in the East China Sea, are converted to long-term fishing from short-term fishing for reasons such as cost reduction due to the sudden rise of oil prices and the performance improvement of the fishing vessels. The number of vessels in marine accidents decreased gradually from 1999 to 2002 and for nearly 7 years from 2002 to 2008, the annual average of marine accidents stayed at 97 vessels. This is seemed to be the result of a change in the policy of either the central or local government and largely associated with changes in the way of statistical processing. This tendency is resulted in lower number of the accidents due to careless navigation which can be viewed as a human error than the number of marine accidents due to poor maintenance as a cause of mechanical failure in the same period. The increase rate in the marine accidents of Jeju Island-based fishing vessels is greater than that of other area-based fishing vessels among the fishing vessels operating in coastal and near sea around Jeju Island each year.

해양안전심판원에 따르면 선박의 등록 척수는 점차 줄어드는 추세이지만, 전체 해양사고 척수와 충돌사고 척수는 증가 추세를 보이고 있다. 2008년부터 2012년까지 최근 5년간 해양사고 발생 현황을 분석해 보면, 해양사고에서 충돌사고가 37 %로 가장 높게 나타났으며, 이러한 충돌사고에서 어선이 58 %로 가장 많이 발생되었는데, 그 중에서도 20톤 미만의 소형선박의 충돌사고가 26 %로 가장 많은 것으로 확인되었다. 또한, 충돌사고의 절반이 넘는 56 %의 선박이 충돌직전까지 상대선박을 발견하지 못한 것으로 분석되었는데, 이러한 사실은 충돌사고가 대부분 경계소홀로 인하여 발생한 것임을 알 수 있다. 따라서 이러한 충돌사고를 줄이기 위해 어선의 운항특성 및 운항과 관련된 제반 규정을 검토하여 어선의 승선 인원, 교육 및 훈련, 그리고 항해장비 측면에서 개선 및 보완할 수 있는 방안을 제시하였다.

In case of many products placed on the production line in automobile production, some line is personnel visually identifiable, such as CCTV, while the rest areas is not identifiable. However, because the position of accidents is not scheduled and every accidents should be analyzed at every point, every accidents is not easy because you need to an immediate response. The record cause of the accident is difficult to understand, not until after the accident for the accident cause analysis of fragmentary and mechanical information so that future accidents have difficulty measures be established. To prevent this, the car accident occurred in the manufacturing plant personnel to deploy and monitor in every area of enterprise is too burdensome labor costs too high. In this study, automated car production plant and load transfer system crash, accident collision and records are available for real-time wireless transmission, the administrator determines that situation can be immediately developed the electronic mono rail system(EMS). You will start to develop the control of EMS and stop control is critical for the correct parts first perform CAE analysis to develop a prototype.

The purpose of this study was to identity the relationships of sub factor among the brain dominance thinking types(A,B,C,D quadrant thinking type) is based on the Whole Brain Modal and self-leadership by Manz. The subjects were 102 undergraduates students from the Hoseo university in Cheonan. The results of this study as follows ; first, the brain dominance thinking type A was the highest and type C was highly rated. Second, the brain dominance thinking type A was not correlated type C and type D. Third, the brain dominance thinking type C and self-leadership sub factor was significantly positively correlated.

The purpose of this study was to investigate the effect of risk awareness on injury experience in quick delivery service workers. Risk awareness has complicate characteristics such as its level of worker and worker's decision about the level of other's risk perception. Data were collected by interview survey with structured questionnaire about injury experience, risk perception, work characteristics, and socio-demographic characteristics of quick delivery service workers by cross sectional survey design in 2012. The sample size was 120 respondent of quick delivery service workers. Statistical method for this study was hierarchical logistic regression method with 3 different models using socio-demographic characteristics and work characteristics and risk perception, etc. The difference between the level of risk perception of quick delivery service and other’s was statistically significant effect on the experience of injury. Especially the higher the level of risk perception of quick delivery service workers is than other’s, the lower the injury experience of quick delivery service worker is. The limitation of this study can be found in survey design. The future study for investigation of mechanism of the combined effect of risk perception of quick delivery service workers and others on injury experience.

The purpose of this study was to verify the relationship between fire fighter's musculoskeletal disorder related observable symptom and their absence from disease and accident. Online questionnaire was distributed with a total of 7,673 fire fighters, and statistical analysis was conducted to the collected data. The result shows that on a one year basis, patients with musculoskeletal disorder related observable symptom felt symptom in sequence of back, shoulder, neck, knee. The result verified that 12.9% of absence of disease and 5.9% of absence of accident experienced these symptoms. Both absence from disease and absence from accident showed body part symptoms related to neck and shoulder. This study ascertained the relationship between fire fighters' absence and their musculoskeletal disorder related observable symptom. The author hopes this study to be used as a basis of precautionary program for absence management.

Abstract In Korean society, the theme of human errors in railway has been emerging as a critical issue. As far as human error studies are concerned, main trend has been inclined to be led by industrial engineering and systems science. Apart from those trends, this study empirically highlighted the relationship between depression, which has been a frequent research subject in the medical science and psychology, and accidents, with setting depression as an exogenous variable and cognitive failure and mistake as endogenous variables, respectively. Results of hypotheses test for the 204 respondents showed that driver's depression has a significant effect on accidents mediated by cognitive failure and mistake. This findings suggest the need for exploring the diverse latent factors causing human errors and for understanding the complex cognitive process as well as for establishing integrative countermeasures to mitigate human errors.

Because the damages of corrosion resulting from the chloride ion are very serious, many research studies have been performed to measure the penetration depth of the chloride ion. However, there is a problem with data selection obtained from collection during experiments. In this study, it appears that the collected data are not conformed to a normal distribution. The result of this study will play a very important role, as a first step for the development and construction of a forecasting system to help determine a reliable service lifetime of marine structures.

PURPOSES : Although numerous researches have been studied to reveal accident causations for road intersections, there are still many research gaps for road segments. It is mainly because of difficulty of data and lack of analytical method. This study aims to study accident causations for rural road segments and develop accident modification factors for safety evaluation. The accident modification factors can be used to improve road safety. METHODS : Methods for developing AMF are diverse. This study developed AMFs using accident prediction models and selected explanatory variables from the accident models. In order to select final AMFs, three different methods were applied in the study. RESULTS: As a result of the study, many AMFs such as horizontal curves or vertical curves were developed and explained the meanings of the results. CONCLUSIONS : This study introduced meaningful methods for developing significant AMFs and also showed several AMFs. It is expected that traffic or road engineers will be able to use the AMFs to improve road segment safety.
