Effective use of traffic marking can lead to driver's safer driving by speed management and visibility enhancement. One of the critical factors in designing traffic marking is how to incorporate human factor issues into the design process. This study presented a methodology for evaluating the effectiveness of Hi-pass marking on Korean freeways based on kansei engineering. Hi-pass marking scenarios made by a virtual reality tool were used to evaluate the user's perceptions. Various combination of chevron angles and peripheral transverse(PT) bars were used for the evaluation. The results show that the most effective scenario is a combination of 60 degree chevron angle and an askew parallelogramshaped PT bar shaped. It is expected that the proposed method and outcome will be useful for making safer driving maneuvers.

People use social media platforms such as Twitter to leave traces of their personal thoughts and opinions. In other words, social media platforms retain the emotions of the people as it is, and accurately understanding the emotions of the people through social media will be used as a significant index for disaster management. In this research, emotion type modeling method and emotional quotient quantification method will be proposed to understand the emotions present in social media platforms. Emotion types are primarily analyzed based on 3 major emotions of affirmation, caution, and observation. Then, in order to understand the public's emotional progress according to the progress of disaster or accident and government response in detail, negative emotions are broken down into anxiety, seriousness, sadness, and complaint to enhance the analysis. Ultimately, positive emotions are further broken down into 3 more emotions, and Russell emotion model was used as a reference to develop a model of 8 primary emotions in order to acquire an overall understanding of the public's emotions. Then, the emotional quotient of each emotion was quantified. Based on the results, overall emotional status of the public is monitored, and in the event of a disaster, the public's emotional fluctuation rate could be quantitatively observed.

Human desires start from the factors that make up the basic living environment. The development model of the safety guidelines will start from a sense of departure from collective psychology and systemic environment, at the time of inducing threats to threats. The design and methodology of the safety guidelines should be drawn up repeatedly by the sequence of iterative models, and the design methodology should be designed in the chronological order of the public services through the methodology of service design methodology. Various and complex threats attempt to derive insights from the user's perspective and to derive insight into the development of the safety guidelines and the sophistication of the user experience, and to extract insights from the perspective of a user's perspective and supervision model. This derived insight can be implemented as a multi-dimensional service model derived from the same problem consciousness methodology.

With rapid economic development, general demand and interest in surroundings that consist of our lives have grown gradually. In addition, as there has been increased social interest in creating landscape of roads, which considers all important factors from the user's view including accessibility, safety, and psychological stability, efforts to improve quality of roads are required. Therefore it is needed to establish standards on safe and comfort road design based on sensibility satisfaction of road users rather than based on standardized road design guidance from the engineering perspective. To this end, research was carried out to analyze sensibility satisfaction of users about road landscape focused on elements of road cross section in a city. It identified relation between sensibility satisfaction and the elements by using principal and cluster analysis, and the multiple regression models. It also found that user's satisfaction about roads and a road landscape is high with road width (3~5 meters), clear zone (2.2~3.9 meters), road central garden (1.05~1.9 meters), shoulder (0.55~1.43 meters), median (0.65~1.625 meters), the number of travel lanes (2~5), height of trees at the central garden (6.4~15 meters) and height of buildings surrounding roads (18~44 meters or 6~15 floors).

The purpose of this study is to progress the limitations and disadvantages of existing safety clothing by applying high technology to current safety clothing that is produced and distributed only with fluorescent fabrics and retroreflective materials. Therefore, the industrial suspender-type safety belt and engineering technology are introduced, designed, and fabricated to help save a life in an emergency. First, the suspender-type safety belt to be developed is designed to emit light by LED attached to the film, and the body of the belt-wearer is recognized from a distance through retroreflection from the flashing LED. It aims to support people's safety by preventing accidents during roadside work, rescue activities, and sports activities at night. Second, with the development of advanced devices when the user is in an unconscious state due to distress or falls into an unconscious state due to distress or accident, the tilt sensor of the control unit attached to the belt automatically detects the angle of the human body and generates light and sound. It is intended to further enhance the utilization by mounting a sensing and signaling device that generates a distress signal and shaping it in the form of a belt attached to a vest that can be easily detached from the outside of the garment. When the wearer falls due to an accident, the tilt sensor of this belt detects the angle change and then the controller generates a high-frequency sound and repeated LED blinking signals at the same time. In the case of conventional safety vests, it is almost impossible to detect that the person is wearing a vest when there is no ambient light, but in case of the safety belts in this study, the sound and light signals of the safety belt enable us to find the wearer within 100 meters even when there is no ambient light.

국제연합은 1975년에 "장애인 권리선언"을 결의하였고, 1981년을 "세계 장애인의 해"로 결정하였다. 우리나라에서도 1981년 6월 5일, 법률 제 3452호 "심신장애자 복지법"을 제정, 공포하였고 1989년 12월 30일 "장애인 복지법"으로 개정하였다. 한편, 미국에서는 1990년 7월 26일 George Bush 전 대통령이 "The American with Disabilities Act of 1990(ADA)"에 서명하였다. 이 법은 인종, 성별, 출신지, 그리고 종교에 관계없이 장애자에게도 같은 시민 권리 보호를 제공한다는 것이다. 그럼에도 불구하고 장애인을 위해 설계된 건물이나 시설물들이 그렇게 많지 않다는데 그 문제점이 있다. 따라서 본 연구의 목적은 신체 장애인에게 “동등한 생활의 질”을 제공하자는 데 있다. 그에 따른 목표로써 신체장애에 대한 구분이 이루어 졌고, 이동 수단으로서의 wheelchair에 대해 조사되었고, ADA accessibility guidelines가 분석되었다. 또한 인간공학과 감성공학으로 재활공학에 접근하였으며 가상현실이 이용되는 현 추세도 연구되었다. 결론적으로, 제시된 guidelines를 이용하여 가상현실의 세계에서 충분히 simulation을 마친 후에 장애인을 위한 좀더 과학적이고 합리적인 건물 또는 시설물 그리고 wheelchair를 제작할 수 있으면 한다.과학적이고 합리적인 건물 또는 시설물 그리고 wheelchair를 제작할 수 있으면 한다.
