Objective: The purpose of this study is to modify the stroop test to suit the virtual reality driving simulation environment and develop it as a tool to measure the user"s executive function. Background: With the advent of an ultra-aging society, cognitive impairment of the elderly with neurodegenerative diseases is increasing. Accordingly, new cognitive function measurement tools that reflect embodied cognitive theory are being actively studied. As such a tool, a virtual reality environment in which perception-cognition-action can be combined is being used. Method: This scenario was developed to proceed by dividing into three-stage tasks similar to the existing stroop test in virtual reality. However, we changed the color and text of the stroop test to the direction and color of the car"s navigation. Results: Expert evaluation was conducted, and the originality and usability of the vr experiment were highly evaluated, and the complexity and user feedback of the experiment were evaluated low. Conclusion: Scenarios should be modified based on expert evaluation, user evaluation need to be conducted, and we will verify validity.

본 작품은 역사적으로 예술이 감정을 표현하는 방법을 기술이 발전한 현대사회의 동시대적 관점에서 어떻게 표현할 것인가에 대한 의문에서 시작했다. HMD 를 착용하고 VR 영상을 관람할 때 사용자의 뇌파(EEG)를 측정하여, 감정으로 치환하고, 이 비물질적인 감정데이터를 물질적인 LED 키네틱 예술 작품으로 표현하고자 한다.

We proposed a design procedure for Korean Precast Slab Track system. Korean Precast Slab Track system cannot use the same design procedure to German slab track system because of different shapes and some problems. We identified the problems of German slab track design system that cannot simulate effects of loads. This proposed procedure is implemented for the commercial software of ABAQUS. Using this procedure, one can consider uncombined effects between slab panel and hydraulic sub base, effect of close sleepers.

본 연구는 건축물외장색채의 감성어휘 추출을 목적으로 건축물 외장색채를 용도별로 분류하여 현황색채를 조사하고 추출된 색을 바탕으로 연상되는 건축물외장색채 감성어휘를 추출하였다. 대전시를 중심으로 50개의 건축물에서 용도별로 현황색채팔레트가 조사되었으며 이를 바탕으로 ‘도회적인’, ‘세련된’, ‘모던한’, ‘깨끗한’, ‘중후한’, ‘부드러운’, ‘깔끔한’, ‘밝은’ 등의 총56개 감성어휘가 추출되었다. 연구의 결과는 추후 건축물외장색채 이미지평가에 평가도구로 활용하고자 한다.
