본 연구는 고령 운전자의 안전의식에 영향을 미치는 요인을 비교분석하였다. 이를 위하여 대전, 세종, 충남 북 지역에서 영업용과 비영업용 차량을 운전하는 노인 307명을 조사대상자로 하였다. 본 연구에서 자료분석을 위하여 PASW Statistics 18.0을 이용하였다. 주요결과는 다음과 같다. 첫째, 영업용 차량 운전자와 비영업용 차량 운전자의 안전의식 수준은 각각 6.49(SD=1.66)와 6.93(SD=1.42)로 나타나 비영업용 차량의 운전자가 유의미하게 더 높은 것으로 나타났다(t=-3.847, p<.001). 둘째, 조사대상자의 안전의식에 영향을 미치는 요인은 각 집단별로 크게 다른 것으로 나타났다. 영업용 차량 운전자의 안전의식에 영향을 미치는 요인은 안전지향동기, 경제상태, 일일 운전시간, 감각추구성향, 결혼상태 순으로 나타났다. 반면에, 비영업용 차량 운전자의 안전의식에 영향을 미치는 요인은 안전지향동기, 건강상태, 사고 경험 유무, 감각추구성향 순으로 나타났다. 이러한 연구결과에 기초하여 영업용과 비영업용 차량을 운전하는 노인들에 대해 집단별로 안전의식을 향상하고, 교통사고를 방지할 수 있는 몇 가지 실질적인 방안을 제시하였다. 나아가 고령화가 급격히 진행되는 한국에서 노인 교통복지의 정책방향을 재정립하는데 기초자료를 제공하고자 하였다.

본 연구는 사업용 운전자들의 상황인식 능력이 사고 유발 회수나 심각성, 벌점 등과 관련성이 있는지 알아보기 위한 목적을 가지고 진행되었다. 이를 위해 상황인식의 지각 단계와 이해 단계의 능력을 측정하기 위한 상황지각 검사와 위험판단 검사를 제작하고, 운전정밀 특별검사 대상자인 사업용 운전자 228명에게 새로 개발된 시뮬레이터 기기를 이용하여 상황지각 검사와 위험판단 검사를 시행하였다. 개발된 과제의 수행 결과는 최종 5등급으로 판정이 내려지도록 설계되었는데 가장 수행이 좋은 경우 1등급, 수행이 나쁜 경우 5등급 판정을 받도록 하였다. 연구 결과, 상황지각 검사에서의 저조한 등급은 누산벌점과 사고 다발도, 안전도 지수와 정적인 상관이 있었으며 위험판단 검사의 등급은 사고 다발도와 안전도 지수와 정적인 상관이 있었다. 이는 사업용 운전자들의 상황인식 능력이 법규위반 및 사고 유발 경향과 관련이 있음을 보여준다.

최근 사업용운전자들의 음주운전이 증가하고 있다. 본 연구는 사업용운전자들의 음주문제행동에 영향을 미치는 요인으로 스트레스 대처방식을 상정하고 스트레스 대처방식이 생활스트레스를 증가시켜 음주문제행동에 영향을 주는지를 알아보고자 하였다. 총 1308명의 사업용운전자들이 연구에 참여하였다. 연구결과, 사업용운전자들의 스트레스 대처방식으로 문제해결, 조력추구, 정서적 완화, 소망적 사고, 수동적 회피 5개 방식이 확인되었으며, 이 중 문제해결, 소망적 사고, 수동적 회피 대처방식에서만 생활스트레스의 매개효과가 관찰되었다. 즉 문제해결 전략을 적게 사용할수록, 소망적 사고와 수동적 회피 전략을 많이 사용할수록 생활스트레스는 높았으며, 이것은 다시 음주문제행동을 높이는 것으로 나타났다. 이러한 결과는 스트레스 대처방식에 대한 운전자 교육의 필요성을 시사하고 있다.

Background: Given the long hours on the road involving multiple and interacting work stressors (i.e., delivery pressures, irregular shifts, ergonomic hazards), commercial drivers face a plethora of health and safety risks. Researchers goal was to determine whether and to what extent long-haul trucker work schedules influence sleep duration and quality. Methods: Survey and biometric data collected from male long-haul truck drivers at a major truckstop in central North Carolina over a six month period. Results: Daily hours worked (mean = 11 hours, 55 minutes) and frequency of working over government-mandated daily HOS regulations (23.8% "frequently or always") were statistically significant predictors of sleep duration. Miles driven per week (mean = 2,812.61), irregular daily hours worked (63.8%), and frequency of working over the daily hour limit (23.8% "frequently or always") were statistically significant predictors of sleep quality. Conclusion: Implications of findings suggest a comprehensive review of the regulations and operational conditions for commercial motor vehicle drivers be undertaken.

This study was conducted to understand sensory characteristics of commercial functional beverages, to analyze and the drivers of liking and disliking of it by Korean consumers. Descriptive analysis and consumer taste testing were conducted with ten commercial products of functional beverages. Samples were consisted of good for beauty, relieving hangovers, and health tonics. For the descriptive analysis, 45 attributes were developed by ten panelists and it shows differences among the all samples. For the consumer testing, 81 panels evaluated the overall liking, acceptance of appearance, odor, flavor, and texture of 10 samples. As a result, attributes of brightness, yellow color, Nurungji flavor, roasted bean power flavor, and milky texture of functional beverages were positive drivers of liking, but attributes of astringent texture, bitter taste, and viscosity were negative drivers of liking on the commercial functional beverages.

Objective: The purpose of this study is to determine the priority of information presentation and the effective menu type to be placed in the center of a gauge cluster display for commercial trucks and to present a set of ergonomic designs for the gauge cluster display. Background: An effective ergonomic design is specifically needed for the development of the gauge cluster display for the commercial trucks, because more diverse and heavier information is delivered to truck drivers, compared to the information to passenger car drivers. Method: First, all the information that must be shown on the commercial truck display was collected. Then, the severity, frequency of use, and display design parameters were evaluated for those information by commercial truck drivers. Next, an analysis on the information attributes and the heuristic evaluation utilizing the display design principles were carried out. According to the results, a design alternative of the main screen to be displayed was constructed by priority. A comparative analysis between the alternative and existing main screens was also conducted to see the efficacy of the designs. Lastly, we conducted an experiment for the selection of menu type. The experiment was conducted using the driving simulator with an eye-tracking device. The independent variables were four types of the menu reflecting the commercial truck characteristics such as grid type, icon type, list type, and flow type. We measured preference, total execution time, the total duration of fixation on the gauge cluster area, and the total number of fixation on the gauge cluster area as dependent variables. Results: Four types of driver convenience information and six types of driver assistance information were selected as the information to be placed primarily on the main screen of the gauge cluster. The Grid type was the most effective among the menu types. Conclusion: In this study, the information that appears on the main screen of the display, the division of the display and the design of the menu type for commercial truck drivers were suggested. Application: This study is expected to be utilized as guidelines on the ergonomic design of a gauge cluster display for commercial trucks.

PURPOSES : This study aims to analyze how the installation of advanced warning devices affects individual drivers' driving behaviors with operating record data collected from 100 vehicles. METHODS : With collected data, the changes in individual drivers' driving behaviors, such as Forward Collision Warning (FCW) and Lane Departure Warning (LDW), were investigated with respect to the cumulative distance traveled and driving time. For the analysis, operating record data collected from 100 vehicles for seven months were used. RESULTS : The results showed that individual drivers' driving behaviors could be categorized into six different types. In addition, most of the drivers showed unstable warning patterns in the initial stage after installation of an advanced warning device. Approximately 40% of vehicles equipped with advanced warning systems were found to have positive effects, indicating that the frequencies of both FCW and LDW had been continuously decreasing after installation of the system. CONCLUSIONS : The warning device might be helpful for making drivers' driving behaviors safer. Driving behaviors during the initial stage of the system installation, which might be regarded as an adaptation phase, were found to be very unstable compared with normal situations, indicating that adequate education and training should be provided to all the drivers to prevent operator disruption at the initial installation of the system.

Background: Truck driving is a highly sedentary occupation that places workers at risk for chronic health conditions, such as obesity and high blood pressure. The primary purpose of this study was to objectively describe truck drivers' typical physical activity (PA) patterns. Methods: We used ~7-10-day baseline PA actigraphy data samples from drivers in the Safety & Health Involvement For Truckers (SHIFT) study (n = 394). Driver PA patterns (e.g., average number of ≥10 minute Freedson bouts per week, time in bouts, and common days/times for PA) were summarized with descriptive analyses. We also compared objective accelerometer data to self-reports. Results: Drivers' weekly PA averaged 14.4 minutes (SD = 37.0), and most PA occurred between 5-6 pm on Tuesdays and Wednesdays. Drivers overestimated self-reported weekly exercise by over 60 min/week compared to accelerometer data. Conclusion: Our results suggest that objective PA assessment may be warranted over self-report when possible, and timing may be key in future PA intervention work with truck drivers.
