In this study of the relationship between preschoolers' visual perception and reading Hangul words, the 287 participants showed significant developmental change in visual perception between three to five years of age. The researcher developed the computer-based screening Test of Visual Perception for Reading (TVPR). Factor analysis confirmed three factors of TVPR : perception of number, direction, and form constancy. These factors correlated highly with four factors of motor-reduced visual perception of the Korean Developmental Test of Visual Perception (Moon et al. 2003). All factors of TVPR explained reading real words and pseudo words; direction and form constancy perception predicted reading low frequency letters. These findings confirm that preschoolers' skills in visual perception contribute to the reading of words in Hangul.

Purpose : This study aimed to evaluate the changes in visual perception and daily life activities after simultaneously applying the visual perception training program and transcranial DC stimulation. Particularly, this study tried to understand what changes in abilities among daily life activities influenced cognition. Methods : This study selected 50 dementia patients to achieve the objective. This study applied transcranial DC stimulation and a visual perception training program to a treatment group (n=25) and a visual perception training program to a control group (n=25). The intervention was applied five times per week and 30 minutes per session (total of 30 intervention sessions). This study measured visual perception functions and daily life activities using MVPT and FIM before and after applying the intervention. Results : The visual perception, mobility of daily life activities, cognition, and total score of the treatment group (n=25), which received the visual perception training program and transcranial DC at the same time, were significantly (p<.05) different between before and after the intervention. Moreover, when the visual perception and daily life activities of the treatment group and those of the control group after implementing the intervention were compared, they were significantly (p<.05) different between the two groups. Conclusion : The results of this study showed that the simultaneous application of the visual perception training program and transcranial DC stimulation was an effective means to enhance the visual perception and daily life activities of dementia patients. The results implied that transcranial DC stimulation, as well as the application of visual perception training program, as well as a visual perception training program, was effective for improving the visual perception functions and daily life activities dementia patients and simultaneous application of the two interventions would increase the effect even further.

시 지각(Visual Perception)은 눈을 통하여 받아들인 사물에 관한 시각적 정보를 중추신경계에서 해석하는 능력이다. 즉, 시각적 자극을 인식하고 변별하며, 그러한 자극들을 선행경험들과 연합함으로써 해석하는 능력을 말한다. 오늘날 시 지각장애의 원인을 밝히는 일과 시 지각 능력의 진단을 통하여 지각장애의 제반 특성을 파악하는 일은 시 지각 장애의 교정이나 시 지각 훈련 프로그램을 통한 치료적인 방법으로 활용된다. 그러나 현재 국내에서 특수교육이나 작업치료, 또는 장애인 복지관의 심리상담에 주로 사용되는 지필(紙筆)방식의 시 지각 능력 진단 도구들은 그 사용에 있어서 문제점 및 한계성이 많이 발견되고 있다. 본 논문은 기존의 문제점을 해결하기 위한 방안으로 데이터베이스로 구축이 가능한 웹 기반 시 지각 발달 진단 프로그램의 모형을 개발하고자 하는 목적을 가진 기초연구라고 할 수 있다. 그 결과 시 지각을 진단할 수 있는 측정유형을 3가지로 분류하였으며, 이를 바탕으로 검사용 그래픽 아이템의 개발방향을 예시하였다. 또한 시 지각 진단 프로그램의 설계 및 구축을 위해 고려해야할 체크리스트 항목과 신뢰도의 타당성 검사를 위한 변인을 추출하여 웹 기반 시 지각 진단 프로그램의 모형개발을 위한 프로세스를 제시하였다.

It is necessary to investigate how age or gender affects visual perception and social skills in late adolescence. A study on the relevance of visual perception in late adolescence, a period that requires social adaptation through the development of social functions, is necessary. The purpose of this study is to investigate the relationship between visual perception and social skills in adolescence. Visual perception and social skill were evaluated for 18-24-year-olds, who are in late adolescence, and were analyzed for gender differences and correlations with chronological age. This study found that there was a difference in visual perceptual function according to gender in late adolescence, and it was significantly higher in men. There was no significant difference in social skills according to gender. However, there was a significantly positive correlation between chronological age and visual perception, but there was no correlation with social skills. These findings provide novel information regarding the developmental course of visual perception and social skill in late adolescence.

This study investigates the effect of visual merchandising congruity perception on brand attitude and purchase intention. In addition, this study examines the mediating role of perceived risk in the process. Four retail fashion brands with classic image were selected in the previous research to avoid the influence of different brand images. Questionnaires were distributed to 200 customers leaving the four fashion retail stores which were chosen by the previous research. A total of 167 completed questionnaires were analyzed using SPSS 18.0 and AMOS 7.0 statistical packages. The results were summarized as follows. First, visual merchandising congruity perception positively affected brand attitude. This result supports the match-up hypothesis. Second, brand attitude positively influenced purchase intention. Third, visual merchandising congruity perception did not directly affect purchase intention. Visual merchandising congruity perception indirectly influenced purchase intention by mediating brand attitude; however, it did not directly influence purchase intention. Therefore, the strategic approaches to enhance favorable brand attitude through visual merchandising congruity perception should be tried. Fourth, visual merchandising congruity perception negatively affected perceived risk. Fifth, perceived risk negatively affected brand attitude. Sixth, visual merchandising congruity perception affected brand attitude by mediating perceived risk. Therefore, it is needed to devise the visual merchandising strategy that lowers the perceived risk in order to make a positive brand attitude.

Objective: The purpose of this study is to identify visual perception of and satisfaction with the orange peel effect of surface. The orange peel effect is a type of finish on painted or coated surface. Background: Gloss paint sprayed on a smooth surface (such as car body, smart phone, and electric home appliances, etc.) should also dry into a smooth surface. Then, a surface resembling the texture of an orange peel can be caused by some factors. The orange peel effect can degrade user's satisfaction with a product. Method: Visual perception and emotional satisfaction were subjectively evaluated using Likert scale. The significance of orange peel effect on visual perception and satisfaction were then analyzed by the analysis of variance. The correlation between visual perception and satisfaction was also analyzed. Results: Surface roughness significantly influenced visual perception and emotional satisfaction. The level of visual perception increased and emotional satisfaction decreased with the increase of orange peel effect. Emotional satisfaction decreased with the increase of visual perception level. Conclusion: It was identified that orange peel phenomenon on surface was a very important factor for emotional satisfaction. The orange peel effect on the surface of a product should be minimized to improve the emotional satisfaction of the product. Application: The result of this study can be applied to the texture design of the body of a car, smart phones, and electric home appliances, etc.
