Purpose: This research aimed to provide baseline data for undergraduate safety education by evaluating paramedic student risk perception and safety practice behavior regarding transport and disaster-related accidents. Methods: A total of 367 paramedic students at three different universities were surveyed using questionnaires. Risk perception questions about hazard, feeling of dread, and uncontrollable factors regarding seven items in transport and disasters were asked on a 7-point scale. Safety practice behavior consisted of 14 transport-related questions and 12 disaster-related questions in 4-point scale. All data were analyzed using SPSS Window 21.0. Results: Of 367 surveyed, 54.8% (201) were females, and 28.9% (106) were freshmen. In risk perception, 'drunk driving' in transport was the highest on average obtaining 6.49 points for hazard and 5.12 points for the feeling of dread. In disasters, 'war' recorded the highest average with 6.61 points for hazard and 5.71 points for the feeling of dread. In safety practice behavior regarding transport and disasters, a higher awareness of the need for safety education correlated with a significantly higher the rate of safety practice behavior (p <.001 respectively). Conclusion: The results indicate that undergraduates have inadequate perception of risk in emergencies. Safety education programs are needed to raise awareness of risks and to increase the safety practice rate.

Purpose: The purpose of this study was to determine the incidence of unintentional-injury and to identify factors related to the high incidence of unintentional-injury in the community in order to provide useful data for the development of prevention and intervention programs aimed at reducing unintentional-injury incidence. Methods: This study utilized data obtained from cross-sectional national surveys conducted for the 2001 National Health and Nutrition Survey targeting 37,769 individuals aged between 0 and 99 years old, which was performed using a face-to-face interview method. Demographic characteristics, unintentional-injury experience, types of injury, and attributes of health behavior were included in the study instruments. Results: About 1.3% of the subjects had experienced unintentional injury that required hospitalization at least once during the past year. Age older than 40 years, male gender, lower education, lower income, and blue collar workers were all significantly and positively associated with increased risk of unintentional-injury. Among the health behavior variables, sleeping less than 6 hours, drunk driving, and binge drinking were significantly associated with unintentional injury, while traffic accidents and falls/slips constituted 80% of all unintentional injuries. Conclusion: Public health efforts to reduce unintentional injuries should target high-risk populations such as males, those with low income and education levels, and binge drinkers.

In this work, we fabricated a gas-sensing device based on porous silicon(PS), and its C-V properties were investigated for sensing alcohol vapor. The structure of the sensor consists of thin Au/oxidized PS/PS/P-Si/Al, where the p-Si is etched anisotropically to be prepared into a membrane-shape. We used alcohol gases vaporized from different alcohol (or ethanol) solutions mixed with pure water at 36$^{\circ}C$, similarly with an alcohol breath measurement to check drunk driving. As the result, I-V curves showed typical tunneling property, and C-V curves were shaped like those of a MIS (metal-insulator-semiconductor) capacitor, where the capacitance in accumulation was increased with alcohol vapor concentration.

This study analyzes traffic accident severity of old age drivers in fourteen cities and counties of Jeonbuk Province. It is assumed that traffic accident effecting factors have two staged structure by personal and driving environment and urban characteristics. Multilevel Analysis Model is used under the assumption of hierarchical characteristics to analyze factors effecting severity. As the driver's age increases after sixty-five years old, accident damages become severe. The drunk driving is likely to make traffic accident damage more severer. The number of fatal accident by old age drivers is about three time more than by no old age drivers. Old age drivers have higher number of night traffic accidents but severer ones in daytime. Old age drivers show the higher number of traffic accidents but severer ones in fine weather. Wet road surface also influences damage severity and especially old age drivers show higher serious damage and fatal than no old drivers.

PURPOSES: The number of traffic accidents in 2010 was 226,978 in Korea, a high percentage of which up to 12.61% was due to drunk driving. As it is expected that the number of traffic accidents will increase because of the drastic increase of the number of vehicle registrations and the prevalent drinking cultures, it is necessary to understand the driving characteristics of drunken drivers to lower the increasing rate. METHODS: This study, therefore, comparatively analyzes the two groups - one group before drinking and the other after drinking - based on the graph, and implements the correlation in each scenario(1,2,3). scenario 1. appearance of jaywalkers; scenario 2. appearance of an illegal left-turning car; and scenario 3. appearance of a vehicle and a person as obstacles to the driver after an accident. RESULTS: The comparative analysis of speed shows that the group after drinking was 50km/h faster than the group before drinking in Scenario 1, 20km/h in Scenario 2, and 15km/h in Scenario 3 respectively. In the comparative analysis of acceleration, the average level of the group after drinking was 0.15 higher than that of the group before drinking in Scenario 1, 0.30 in Scenario 2, and 0.15 in Scenario 3. In the comparative analysis of deceleration, the average level of the group after drinking was about 0.4 lower than that of the group before drinking in Scenario 1, 0.35 in Scenario 2, and 0.2 in Scenario 3 respectively. In the comparative analyses, the item of speed, acceleration and deceleration was of significance for each group in Scenarios. CONCLUSIONS: The comparative analysis demonstrated that there is a difference between the group before drinking and the group after drinking. In the analysis of correlation in each group, it was proved that the drunken group was of significance.

Traffic safety has been dramatically enhanced thanks to recent improvements in traffic environment. Nonetheless, many traffic accidents occur due to unchanging driving practices. Therefore, this study addresses the issues of traffic fine and penalty fine policies, and seek appropriate levels of traffic fines through a public attitude survey. For this purpose, a survey was conducted on 905 adult drivers over 20 years of age from 15 provinces and metropolitan cities. Analysis results are as follows. First, traffic environment in South Korea is generally not safe. Respondents perceive violation of traffic laws such as reckless driving, speeding and drunk and driving as an important cause. Second, 61.6% of respondents experienced over one speeding annually, but only 15.2% of respondents were caught in the last three years. Third, opposition to levels of traffic fines has decreased over the past, and responses were more positive when more information was provided. Fourth, to deter moral hazard of paying traffic fines to avoid traffic penalty points, traffic fines should be at least 50,000~70,000 won higher than penalty fines. Fifth, there was less opposition to implementation of accumulated penalty policy compared to income-based differential fine levels. Sixth, traffic fines for different types of traffic violations need to be reorganized. In conclusion, this study suggests the following policy improvements for the current traffic fine and penalty fine policies for violation of traffic laws. First, enough understanding and consensus must be developed for policy improvements. Second, administrative sanctions such as giving penalty points should be considered rather than financial sanctions. Third, there should be policy improvement for accumulative penalty. Current acts of traffic law violation should be reorganized.

There is a difficulty in preventing drunken driving by enforcing alcohol control on the sea due to the environment of Marine transportation rather than roads. In the previous study, we proposed the algorithm, that was developed to identify the voices changed according to be drunk. Using the developed algorithm, it became possible to know the possibility of drinking by long distance ship operators and crew members. In that method drinking can be measured in real time, no matter how far the distance is, if the interception is through a voice that can be transmitted over a distance, rather than a short distance. When communicating voice using the VTS wireless devices, clipping occurs when that environment is uneven, and the rate of judgment of the possibility of drinking may be lowered. Therefore, in this paper, we proposed an enhanced method to compensate the signal in order to reduce the error rate of the possibility of drinking due to distortion of the speech signal.

Purpose: The purpose of this study was to identify the factors related in an urban resident's drinking state and drinking problem. Methods: The data was collected from Oct. 2008 to Sep. 2009. Data were collected by questionaire from 359 urban resident over 20 years old and drinking experience residing. The instruments for this study were the alcohol use disorder identification test(AUDIT), the related factors of alcohol drinking. The data were analyzed using descriptive statistics, t-test, ANOVA, hierarchical multiple regression with the SPSS 18.0 program. Results: The problem drinking were 35.7% on AUDIT. (a) Male had significant effect on drinking problem; (b) If you drank alcohol for the first time prior to high school graduation had significant effect on drinking problem; (c) Permanent rental or unlicensed residential had significant effect on drinking problem; (d) Experience in drunk driving had significant effect on drinking problem. Conclusion: It is nessary to education at early childhood for the prevention of drinking problems and regular management for high risk.

Objectives: Few studies have focused on health behaviors and health status among teachers even though these are one of principles and values of WHO's Health Promoting Schools. In this study, we described health behaviors and health status among teachers and explored the differences of these by personal and school characteristics. Methods: A stratified and random cluster sampling design was used to obtain a cross-sectional sample. A total of 59 elementary, middle and high schools in Seoul and Gyeonggi areas were included in which 333 teachers (males 40.6%, females 59.4%) participated in this survey. Chi-square tests were conducted with SPSS 17.1. Results: Overall, health behaviors and health status among teachers were better than the general public according to Korea National Health and Nutrition Examination Survey. Male and middle/high school teachers had higher prevalence of alcohol dependence and of driving under the influence of alcohol. Also, their rate of wearing seat belts were lower compare to female. In other hand, female, health and nutrition teachers, rural school teachers had lower prevalence of meeting recommended levels of physical activity. Underweight were more prevalent to them in contrast to male with higher prevalence of obesity. In addition, teachers of health promoting schools were not likely to ride on a car with a drunk driver. They also have a lower prevalence of skipping breakfast and have higher positive perception of health for themselves. Conclusion: Teachers' health should be given higher concerns as a key component of school based health promotion. Gender and age specific programs should be considered to develop health promoting programs for them.
