Purpose: The purpose of this study was to understand the meaning of the driving force of life experienced by the elderly and the realistic structure of their experience. Methods: The research question was "What is the essential meaning of the driving force experienced by the elderly?". Data were collected from individual in-depth interviews between March, 2017 and May, 2017 and analyzed using Van Manen's hermeneutic phenomenological methodology to identify the essential themes of their experience. Results: Through the analysis process, 22 themes and 14 essential themes were derived. The 14 essential themes of the driving force of the life of elderly were as follows: 'Memories from the past', 'Poverty to escape', 'Hand down family's heritage', 'A body bound by marriage', 'A body necessary for old age', 'A dignified body even if they grow older', 'A body that does not want to fall', 'A fruit of my life', 'Mature real love', 'Unchanging fraternity', 'Extended family', 'An old friend with whom share my heart', 'Satisfied with the situation', and 'Expanding the breadth of life'. Conclusion: Nursing programs that assess the driving force of life supporting the elderly and supports the driving force of such a life should be developed.

The directions of the road are divided into two, the right-hand side and left-hand side of the road, by the convention and specific native method in the world. This paper deals with the characteristics and behaviors of drivers who are accustomed to driving on right-hand side of the road, drive with a handle on the left-hand side, and comparing with left-hand side drivers. The driver's eye movements were measured by eye camera and questionnaires were used for measuring subjective evaluation such as driving mental workload. The experimental results indicated even if the experts who had much experience on right-hand side driving, they had lower driving skill than novice driver, accustomed to driving on left-hand side. In terms of mental workload, MCH rating scale and MNASA-TLX, the right-hand side drivers were in lower stress condition than the left-hand side drivers because of having much driving experience. However, they conducted a few mistakes by confusing the position of turn signal and windshield wiper because of their driving habit or traits and it lead to operation mistakes. These results can be applied effectively to develop the driving support information with changed environments.

본 연구는 운전자의 조심성에 초점을 두고 고령운전자와 청소년운전자의 운전확신수준과 운전행동과의 관계를 알아보았다. 우선, 운전확신수준을 측정하기 위한 도구를 제작하여 사용하였으며, 조사대상자들의 운전경력, 주행거리, 위반경험, 사고경험을 함께 조사하였다. 조사대상자는 만 25세 이하 청소년운전자와 만 65세 이상 고령운전자 325명이었으며, 고령운전자의 자료는 1:1 인터뷰를 통하여 수집하였다. 먼저, 운전확신수준의 구조를 알아보고자 요인분석을 실시하고, 고령운전자와 청소년운전자의 운전확신수준을 비교하였다. 그리고 고령운전자와 청소년운전자의 운전확신수준과 운전행동과의 관계를 알아보았다. 운전확신수준은 '운전상황', '안전운전', '운전능력', '주의'의 네 요인으로 이루어져 있었으며, 고령운전자의 운전확신수준은 청소년운전자의 운전확신수준보다 낮은 것으로 나타났다. 고령운전자 집단에서는 운전확신수준과 운전경력, 위반경험이 강한 상관관계를 가지고 있었고, 청소년운전자의 운전확신수준은 운전경력, 주행거리, 위반경험, 사고경험과 강한 상관관계를 가지고 있는 것으로 나타났다.

대화형 AI 스피커가 보편화되면서 음성인식은 자율주행 상황에서의 중요한 차량-운전자 인터랙션 방식으로 인식되고 있다. 이 연구의 목적은 반자율주행 상황에서 음성뿐만 아니라 AI 캐릭터의 시각적 피드백을 함께 전달하는 멀티모달 인터랙션이 음성 단일 모드 인터랙션보다 사용자 경험 최적화에 효과적인지를 확인하는 것이다. 실험 참가자에게 주행 중 AI 스피커와 캐릭터를 통해 음악 선곡과 조정을 위한 인터랙션 태스크를 수행하게 하고, 정보 및 시스템 품질, 실재감, 지각된 유용성과 용이성, 그리고 지속 사용 의도를 측정하였다. 평균차이 분석 결과, 대부분의 사용자 경험 요인에서 시각적 캐릭터의 멀티모달 효과는 나타나지 않았으며, 지속사용 의도에서도 효과는 나타나지 않았다. 오히려, 정보품질 요인에서 음성 단일 모드가 멀티모달보다 효과적인 것으로 나타났다. 운전자의 인지적 노력이 필요한 반자율주행 단계에서는 멀티모달 인터랙션이 단일 모드 인터랙션에 비해 사용자 경험 최적화에 효과적이지 않았다.

연구는 보호/비보호좌회전(PPLT) 교차로에서 공격적 운전행태의 영향요인에 대한 분석을 군산시를 대상으로 한다. 로지스틱 회귀모형 결과 운전자의 나이와 운전경력이 증가할수록 비첨두시간대, 동승자가 없는 경우, 운전경력이 많은 경우, 승용차, 남성 등이 대향차량에 영향을 주는 공격적 운전행태를 보인 것으로 분석되었다. PPLT 교차로상에서 비보호 좌회전시 대향차량까지 충분한 거리가 확보되지 않을 경우 공격적 운전행태를 보이게 되는데 공격적 행태를 보인 운전자 속성과 대향차량까지 거리의 관계성을 분석하였다. 나이와 동행자수의 증가, 첨두시간대는 근거리에 위치해 있는 대향차량에 대해 영향을 주는 반면에, 남성 및 운전경력이 높을수록 중거리 및 장거리 대향차량에 영향을 주는 것으로 나타났다. 승용차 보다는 RV 및 대형차량이 거리가 먼 대향차량에 영향을 줄 가능성이 컸다.

To assure the safety of urban railway train, it is necessary to observe the specified driving principles under an essential condition during running on tracks. These principles arises from a great deal of experience for a long time and include safe distance between trains, the railway signaling, block system, regular block of the highest priority and driving prohibition of simple railway vehicle in the main track, etc. Therefore, it is important to apply these principles to domestic urban railway driving regulations and railway vehicle driving regulations. However, domestic urban railway administrator established his own operation rules within the regulation. In this study, domestic urban railway administration's own rules are examined and the appropriate driving regulation on the safe driving principles is proposed.

Objective:This study is on the characteristics of motorcycle accidents occurring in the mail delivery process by skill level. Background: The tendency of delivery postmen's driving in a hurry may become the cause of accidents since there is a constraint that delivery should be completed within a limited time. Method: This study analyzed the traffic accident data of 259 delivery postmen, who had been approved as occupation-related industrial accident victims from 2009 to 2012, by their work experience in view of season, day of the week of an accident occurrence, accident occurrence time, accident cause, collision type, and driving situation. Results: Accident characteristics of delivery postmen show that the ratio of accidents occurring to those who had less than 10 years of work experience was high. There were many motorcycle collisions in winter and summer by season and an unexpected object, along with road condition, took up 70.7% of the accident sources. There were no differences in accident occurrence time, the day of the week, season, accident source, and collision type between the group of delivery postmen with less than 10 years of work experience and those with 10 years or more of work experience. However, there was a difference in distribution of driving condition. Conclusion and Applications: The results of this study can be used to present the policies or guidelines for the accident prevention of delivery postmen since the results show the characteristics of the injured and accident occurrence characteristics in relation with the delivery postmen's motorcycle collisions.

As the high performance computer system increases, improving of reality and usefulness causes the virtual environment of simulator to be used widely as training and assessment tool. Although some domestic companies have developed train driving simulators since about mid of 1990s, accumulation of technology and experience is not yet sufficient compared to foreign makers. This paper describes system composition, training and assessment regimes for high level train driving simulator. When the subsystems are designed, comprehension of train system is emphasized and the functions that simulator should provide are discussed.

The continuous development of in-vehicle information systems in recent years has dramatically enriched drivers' driving experience while occupying their cognitive resources to varying degrees, causing driving distraction. Under this complex information system, managing the complexity and priority of information and further improvement in driving safety has become a key issue that needs to be urgently solved by the in-vehicle information system. The new interactive methods incorporating the augmented reality (AR) and head-up display (HUD) technologies into in-vehicle information systems are currently receiving widespread attention. This superimposes various onboard information into an actual driving scene, thereby meeting the needs of complex tasks and improving driving safety. Based on the qualitative research methods of surveys and telephone interviews, this study collects the information needs of the target user groups (i.e., beginners and skilled drivers) and constructs a three-mode information database to provide the basis for a customized AR-HUD interface design.
