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.

This study was intended to validate and develop the driving stress scale. In a preliminary investigation, literature studies on the stress and open questionnaire were administered and examined in four regions in Korea. As a result, 121 items driving stress questionnaire were developed. In the study, this driving stress questionnaire was examined to 450 drivers located seven regions in Korea. The factors analysis revealed 5 meaningful factors[(Progress Obstacle: PO), (Traffic Circumstance: TC), (Accident & Regulation: AR), (Regulation Observance: RO), (Time Pressure: TP)] with 38 items. When internal consistency for each 5 factor was calculated, all sub-scale revealed a satisfactory level of Cronbach's α. Also, correlations with Driving Behaviour Inventory-General Driver Stress(DBI-GEN) and risk driving behaviors(speed driving, drunken driving, offence accident, defence accident) supported consistently validity of the Driving Stress Scale(DSS). Finally the result were discussed and implications are suggested for future studies.

This study aimed to expand and reconstruct the Driving Behavior Determinants' factors in order to confirm the relationship between Driving Behavior Determinants(DBD) and drivers' reckless driving behavior level. To expand the structure of DBD, drivers anger, introversion and type A characteristics were added, which were never considered as related factors in existing DBD studies before. The correlations between the new factors of DBD and reckless driving behavior(includes driver's personal records of driving experiences for the last three years) were verified. A factor analysis result showed us that new DBD questionnaire consists of five factors such as, 'Problem Evading', 'Benefits/Sensation Seeking', 'Anti-personal Anxiety', 'Anti-personal Anger', and 'Aggression'. Also, reckless driving behavior consists of 'Speeding', 'Inexperienced Coping', 'Wild Driving', 'Drunken Driving', and 'Distraction'. The result of correlation between the DBD and reckless driving behavior indicates that inappropriate level of DBD is highly correlated with dangerous driving behavior and strong possibilities of traffic accidents. Based on these results, we might be able to discriminate drivers according to DBD level and predict their reckless driving behavior through a standardization procedure. Futhermore, this will make us to provide drivers differentiated safety education service.

This article evaluates the effects of eight traffic safety policies such as traffic accident reduction campaign, the seat belt law, three strike out driving while intoxicated, rewarding for reporting traffic offenders on the number of accidents and fatalities. Intervention analysis of time series is used to compare the monthly accident and fatalities with the before and after reinforcement. The results indicate that no significant impact of the traffic enforcement measures on reducing the number of accidents and fatalities.

한국도로공사가 제공하는 자료에 따르면 운전자 4명 중 1명은 졸음운전을 경험해 보았다고 말한다. 또한, 졸음운전 사고의 치사율은 건당 4명으로 전체 교통사고 치사율의 2배이며, 그 위험성은 음주운전보다 크다고 알려져 있다. 이러한 문제를 해결하기 위해 졸음운전 감지 시스템이 국내외에서 활발히 연구되고 있다. 본 논문에서는 졸음운전 감지 시스템과 더불어 졸음운전을 예방하는 시스템을 제안하고자 한다.

Vehicles are used in daily life as convenient transport, it is important to authenticate driver because vehicles are controlled by driver. Especially, in these days, there is a discussion on introduction of Driving Under the Influence car-starting locking device installation for preventing accidents caused by Driving Under the Influence of alcohol, these car-starting locking device installation requires a lot of money and time. Suitable user authentication for solving user's inconvenience during the disabled and men of national merit to receive discount benefits is needed. In this paper, For solving these problems, we propose the efficient vehicle control and user authentication system for preventing driving under the influence and providing the disabled and men of national merit benefit based on driver authentication by using user's smartphone NFC communication and user's biometric information.

The aim of this study was to evaluate the variability of the blood.breath ratio (BBR) value and to rationalize the determination of ethanol in breath for evidential sobriety testing. In the experiment forty eight healthy persons, 24 men and 24 women, took part. The experiment included the experimental condition such as sex(2),the type of alcoholic beverage(2; soju, whisky), the type of food(2;kimchi stew, pork belly) and the amount of ethanol consumed(2; 0.35g/kg, 0.70g/kg, based on body weight ) according to 24 factorial design by orthogonal arrays. Breath and blood sample were taken each 8 times and 5 times after the end of drinking. The blood and breath alcohol measurements were highly correlated (r = 0.973). The Results of four way analyses of variance revealed a significant 'the type of food' effect for maximum BrAC (F (1, 43) =5.1, pp<.029), but no significant effect in the type of alcoholic beverage and sex. The overall blood/breath ratio (${\pm}$ SD) was 2295${\pm}$403 and the 95% confidence interval were 1489 and 3101. In spite of these variations, at this time, it seems to be reasonable that apply 2100:1 conversion factor to breathalyzers, because most of the subjects showed the blood.breath ratio of over 2100:1 at least 30 minutes or more passed from the time of drinking as shown in this study.

The present authors had conducted several researches(parking violation, traffic signal violation, speed violation, drunk-driving) on driving behaviors of the Korean people focused on cultural psychological perspective. This paper was designed to summarize these previous results. Although each research had dealt with different violation behaviors on driving, there were lots of similarities on the basis of violation. The results reveal the following rationale for incurring violation behaviors. First, most people reported that they violated the rule to pursuit short-term benefit. Second, the violators' psychological characteristics are described in terms of self-centered and self-justification. In addition, the respondents have justified their violated behaviors since the outcome is disadvantageous for the drivers. Furthermore, the violators' are found to possess a permissive attitude toward the other violators'. Finally, the implications of these studies were proposed. All of these findings were discussed in relation to the Korean culture.
