The purpose of this study was to measure safety-awareness among elementary students, identify their safety-practices and actual status of accidents. The study was also done to acquire basic information on safety education to help students be more aware of safety, and more active in accident-prevention activities. A random sample was taken of 763 5th and 6th grade students in 4 different elementary schools in Seoul. Of the 735 questionnaires collected, 684 were complete and were used in the analysis. SPSS was used to analyze the questionnaires. The results are summarized as follows. First, the overall safety-awareness score was relatively high at 139.06 of a maximum of 164. and respondents were most conscious of the section on Home Safety. Second, the safety-practices of the respondents was at the middle level with a mean score of 56.01 of a maximum of 80. The factors affecting the safety-practice of the respondents were education of their parents, recognized learning proficiency, awareness of need for safety education, and level of safety-education conducted by parents. Third, $53.4\%$ of the respondents had experienced one or more accidents during the past year. Most of the accidents occurred during play and recreation and home accidents were the most frequently reported accidents. The risk factors related to the occurrence of accidents were gender, relationship with friends, recognized learning proficiency, and awareness of traffic safety. Forth, higher safety-awareness was found to be directly related to higher safety-practices. Respondents with lower safety-awareness reported higher rate of accidents. In view of the results so far achieved, habituation and formation of safety-oriented actions among students are highly required to prevent accidents. In order to do that, development of safety-awareness and in-life enforcement of safety-practice need to come first.

The purpose of this study was to identify the accidents happened in the college dental laboratory technique classes and to realize the level of safety education for the dental laboratory technique major students. The research data were collected from a self-administered survey distributed to the conveniently selected college students whose majors were dental laboratory technology in Suwon, Daejeon, Daegu, Kimcheon, and Icsan. The study participants were 422 freshmen, sophomore and junior students in the selected cities. All collected survey responses were encoded and analyzed in SPSS 12.0. The findings were as follows. 1. The students who had any accidents in their laboratory classes were 36% and the other 64% answered 'no.' 2. Most injuries which the participants had were not significant. 3. The medical treatment periods of most injury cases were less than one week; however, approximately 20% of the self-reported injury cases reported that their treatment periods were longer than one week. 4. The body parts frequently injured from accidents were hands with 84.7% and arms, eyes, face, head, and legs in order. 5. Concerning the materials involved in the laboratory classes, most accidents happened when working with wax in 59.9%, with plaster in 52.3%, with wire in 39.8%, with alcohol in 34.6%, and casting iron in 22.2% in order. 6. The accident-prone laboratory methods were polishing with 53.5%, pickling or sanding with 17.4%, and casting or burning with 5.8% in order. 7. Most students wore their laboratory gowns well; however, few students wore mask before dust-involved jobs. Furthermore, only 57.1% students answered their laboratory fans worked during the polishing job. 8. Approximately 54% participant students answered that they took laboratory safety education when necessary only from the class instructors. 9. The 76.1% students responded that they needed laboratory safety education at least 1-2 times every semester. 10. The survey participants answered that the primary factors for injury prevention in their laboratory were taking safety education, wearing safety equipments, and providing safety-focused facilities. Concludingly, comprehensive evaluation and monitoring for potential risk factors from both the human side and the environment side should be continually provided to minimize the college laboratory accidents.

Using ALOHA and PHAST Program, it was modeled assuming the leakage accident scenarios of chlorine which is designated as accident preparation chemical in chemical control act. End-point distances corresponding to ERPG-2 concentrations were calculated while varying annual mean temperature, wind speed, humidity, and atmospheric stability. The calculated endpoint distance values were compared and the correlation with each meteorological factor was analyzed. And we also investigated strengths and weaknesses of ALOHA and PHAST. The results show that ALOHA has little or no correlation with annual average temperature, humidity and it has a large correlation with wind speed and atmospheric stability. In the case of PHAST, the end-point distances were correlated with all the meteorological factors such as average annual temperature, wind speed, humidity, and atmospheric stability, Among them, the effect of atmospheric stability were the largest.

It is necessary to control and evaluate human factors to reduce economic loss by major accident in toxic gas facilities. Conventional works to evaluate hazards have been focused on mechanical and systematic failure, while only a little works have been studied on managing human errors. In this work, a classification system of performance shaping factor (PSF) was suggested to consist human error in managing accident in the toxic gas facilities. Four types of PSFs (human, system, task characteristics, and task environment) were collected, reviewed, and analyzed to be categorized selected according their characteristics of situational, task, and environmental parameters. The PSFs were further modified to set up PSF systems adequate to evaluate human error, and the proposed system to consist PSFs to evaluate human error was further studied through accident analysis in toxic gas facilities.

Objective: This study was designed to evaluate the etiological factors of the PTSD(post traumatic stress disorder) by examining the relationship between severity of physical trauma and subsequent the severity of PTSD symptom in traffic accident related PTSD patients. Method: Subjects were 21 psychiatric inpatients with history of traffic accident related PTSD(DSM-IV criteria), the purpose of evaluation of mental disability and no evidence of organic brain leisons. The severity of physical trauma was assessed by McBride number of nonpsychiatric department and the presence / absence of loss of conciousness. The severity of PTSD symptom was assessed by Hovens' self rating inventory for PTSD. And then we evaluated the correlation between these two factors. And we also evaluated relationship between severity of PTSD symtom and clinical variables. Results : There were no significant relationship between McBride number of nonpsychiatric department severity and symptomatic severity(r= 0.17, p<0.05), the presence / absence of loss of conciousness and symptomatic severity(p>0.05). And significant relationship between symptomatic severity and clinical varibles such as sex, education level, marital status(p<0.05). Conclusions : These data did not support data of previous studies that traumatic severity was correlated with symptom severity but, suggested that other variables affecting the severity of PTSD symptom is more important indirectly. And that the 'trauma' in PTSD is psychological meaning rather than physical meaning is also suggested.

Recently, IITS (intelligent integrated transportation system) has been important topic in Smart City related industry. As a main objective of IITS, prevention of traffic jam (due to car accidents) has been attempted with help of advanced sensor and communication technologies. Studies show that car accident has certain correlation with some factors including characteristics of location, weather, driver's behavior, and time of day. We concentrate our study on observing auto correlativity of car accidents in terms of time of day. In this paper, we performed the ARIMA tests including ADF (augmented Dickey-Fuller) to check the three factors determining auto-regressive, stationarity, and lag order. Summary on forecasting of hourly car crash counts is presented, we show that the traffic accident data obtained in Korea can be applied to ARIMA model and present a result that traffic accidents in Korea have property of being recurrent daily basis.

Although the Korean government (Ministry of Ocean and Fisheries) and related organizations are enforcing many policies to improve the marine safety of vessels with weak safety management, the effectiveness of each policy is deficient due to the lack of a risk assessment method for ship safety management. Most previous studies in Korea of the risk assessment of ships only dealt with fragmentary risks of individual marine accident risks, so a new assessment method for comprehensive marine accident risk is needed. Examples of comprehensive risk assessments for ship safety management are the selection method for inspection targets by the Port State Control and the Norwegian Maritime Authority. In this study, indicators for the comprehensive risk assessment of ship safety management were developed for and applied to coastal/offshore fishing vessels that occupy a high proportion of the registrations and marine accidents in Korea. As a result, the risk of each ship was confirmed quantitatively, and a ranking of the weakness factors for ship safety management was identified.

On offshore platforms, oil and gas leaks are apt to be the initial events of major accidents that may result in significant loss of life and property damage. To prevent accidents induced by leakage, it is vital to perform a case-specific and accurate risk assessment. This paper presents an integrated method of Ddynamic Qquantitative Rrisk Aassessment (DQRA)-using the Decision Making Trial and Evaluation Laboratory (DEMATEL)-Bayesian Network (BN)-for evaluation of the system vulnerabilities and prediction of the occurrence probabilities of accidents induced by leakage. In the method, three-level indicators are established to identify factors, events, and subsystems that may lead to leakage, fire, and explosion. The critical indicators that directly influence the evolution of risk are identified using DEMATEL. Then, a sequential model is developed to describe the escalation of initial events using an Event Tree (ET), which is converted into a BN to calculate the posterior probabilities of indicators. Using the newly introduced accident precursor data, the failure probabilities of safety barriers and basic factors, and the occurrence probabilities of different consequences can be updated using the BN. The proposed method overcomes the limitations of traditional methods that cannot effectively utilize the operational data of platforms. This work shows trends of accident risks over time and provides useful information for risk control of floating marine platforms.
