This study analyzes whether a person's visual perception differs according to the kinds of light source. Evaluations of the effects of space, color-tone and texture perception revealed that different kinds of light sources change the perception of finishing material. The perception from directly attached lamps was compared to an environment with both directly attached lamps and supplemental lighting. We found the perception changed with changes in the types of supplemental light source We compared the mean value of each perception and found that perceptions change most when incandescent lights were followed by halogen. Thus, one should account for the changes in perception that occur as a result of these changes.

This study examined the perception of teachers and students on the practice of elementary science class. For this study, an examination tool was made by extracting characteristics of good science class through precedent study investigation and revising it in a questionnaire form of a Likert scale, and conducted to 194 elementary teachers and 320 elementary students. As a result of the study, teachers generally perceived science class positively and teachers with career more than 6 years thought it more positively than them with career less than 5 years. Consequently students have a substantially positive perception level about the practice of the elementary science class, and students of 3th and 4th grade perceived science class positively than 5th and 6th grade in all domains. Finally when analyzing perception difference between teachers and students about the practice of the elementary science class, it appeared that students perceived science class more positively than teachers in most questions.

색채 속성으로는 색상, 명도, 채도로 구분 지을 수 있으며 색채 속성 각각에 따라 색채를 인지하는 특성이 달라진다. 색채를 인지하는 데 있어서 한 가지 색채를 독립적으로 보는 것이 아니라 주변 색채를 함께 보게 되며 주변의 색채 특성에 따라 원본 색채 인지 특성은 달라질 수 있다. 선행된 색채 인지 및 감성 연구는 단일 색채를 대상으로 한 것이 대부분이며 이는 실생활에서 색채를 인지하는 것과는 차이가 있으므로 주변 색채를 고려한 색채 인지 기초 연구가 필요하다. 본 연구에서는 그래픽 영상에서 자주 사용되는 테두리 밝기에 따른 색채 인지 특성을 알아보고자 정신물리학 실험을 진행하고 이를 분석하였다. 밝기에 가장 민감한 시각적 특성을 기반으로 테두리 밝기를 변수로 설정하고 실험 자극색상으로는 먼셀 색채를 사용하여 실험을 진행하였다. 본 연구에서는 진행된 실험 결과를 분석하여 테두리 밝기에 따라 색채를 인지하는 시지각적 특성에 대한 기초 연구 자료로써 유의미 여부를 정의하고 향후 연구 방향을 제시한다.

Through factor analysis, the value perception for natural cosmetics were divided into three factors (social value, emotional and functional value perception). The results of this study were obtained as below. First, in case of the value perception for natural cosmetics by LOHAS class, it was demonstrated that the higher LOHAS classes they were, the higher value perception for natural cosmetics (social, emotional and functional value perception) they had.

본 연구는 전통적 종이형태의 평가와 전자매체를 이용한 평가적용에 따른 지적장애인들의 시지각과 주의집중의 차이를 분석하는 데 있다. 연구대상은 지적장애인 12명이다. 대상자들에게 전통적 평가방식과 전자매체를 활용한 평가방식을 적용하였으며, 그 차이를 비교하였으며, 그 차이를 비교하기 위해 대상자들의 시지각과 시각적 주의집중을 평가하였다. 시지각을 평가하기 위해 Motor free visual perception test-3를 활용하였으며, 주의집중을 평가하기 위해 Trail making test를 활용하였다. 그 결과, 전자매체를 적용한 평가에서 대상자들의 시지각과 주의집중 모두 높게 나타났다. 전자매체는 지적장애인들의 시지각과 주의집중에 영향을 줄 수 있는 요인으로 작용할 수 있다. 따라서, 지적장애인들에게 전자매체를 적용할 경우 이러한 차이를 고려하여야 할 것이다.
