본 논문은 '환경관련 텔레비전 뉴스에서 영상과 자막이 수용자의 의제설정에 영향을 미치는지', 그리고 '텔레비전 수용자의 환경관여도에 따라 영상과 자막이 수용자의 환경 중요성 인식에 미치는 영향에 차이가 있는지' 의제설정효과와 정교화 가능성 모델(ELM)을 이론적 배경으로 살펴본 실험연구이다. 연구결과 환경이슈에 노출된 수용자는 노출빈도가 높을수록 환경을 더 중요하게 생각하며, 그 과정에서 텔레비전의 시각적 요소인 영상과 자막이 수용자들의 환경인식에 영향을 미친 것으로 나타났다. 그리고 영상과 자막이 환경이슈에 관심이 많은 수용자보다 관심이 적은 수용자들에게 통합적 주변단서로써, 환경 인식에 더 큰 영향을 미친 것으로 나타났다. 그러나 영상과 자막이 개별적인 주변단서로써 관여도가 낮은 수용자들에게 더 큰 영향을 미치는 현상은 통계적으로 유의미하게 지지되지 못했다. 그동안 텔레비전 뉴스의 수용자 효과 연구들은 대부분 언어텍스트를 중심으로 이루어짐으로써, 시각적 요소가 수용자에 미치는 영향에 관한 연구는 극히 제한적으로 이루어져왔다. 따라서 본 연구는 최근 미국에서 확산되고 있는 '영상의제설정'이라는 새로운 연구분야의 초기 실험연구로써, 미디어 효과 연구 영역에서 중요한 함의를 가질 수 있을 것이다.

Along with the development of creative design ideas, how to effectively present design concepts is also an important consideration on housing plan process. This could consequently make it possible to automate presentations. In spite of such needs of presentations any significant efforts for the systematic design presentation have not been made yet. The research goals established in order to solve these problems are to develop structures of presentation and analyze the cases of it. This paper explains structures of housing plan presentations in two ways: the compositional elements of panel presentations and the relationships among the elements. The elements include a project title, a synopsis, design concepts, building layouts, floor plan1 and 2, longitudinal and latitudinal elevations, sections, projection and perspective views, and model photographs. Among various relationships among panel compositional elements this study uses relationships based on the Gestalt theory, the balance theory by Rudolf Arnheim and the optical array theory by Gibson. The relationships investigated on the basis of the visual perception theories include the relationships between compositional elements and background space, visual weight balance, horizontal and vertical balances, grouping, and visual layout patterns.

This thesis aims to analyze the visual perceptual effects drawn by 'axial composition and divergence' and to interpret the architecture of Kahn in respect of 'axial composition and divergence'. Axial composition of the form, the location of the entrance and divergence of internal movement were checked up about 53 works by extracting parti which is basic element of spatial composition. The 3D modeling simulation was performed for the selected 10 works in order to analyze the visual perceptual effect due to divergence of the internal movement. The reaction of the observer's actions and visual perception by 'axial composition and divergence' is presented in the following steps. 1. Divergence of the entrance/a panorama of expanding planes. 2. Divergence of internal movement/The process of perception of visual rotation and central spatial form. 'Perceptive form' created by 'divergence' is the result of diverse and flexible series of processes which must be experienced in person in order to reach the space as a room with a definite domain and center.

Driving simulations were performed to evaluate the effect of providing both visual information and body sensory information on changes in steering characteristics and the amount of perspiration in drift cornering. When the driver is provided with body sensory information and visual information, the amount of perspiration increases and the driver can perform drift control with a moderate level of tension. With visual information only, the driver tends to easily go into a spin because drift control is difficult. In this case, the amount of perspiration increases greatly as compared with the case where body sensory information is also provided, reflecting a very high perception of risk. When body sensory information is provided, the driver can control drift adequately, feeding back the roll angle information in steering. The importance of the driver's perception of the state of the vehicle was thus confirmed, and a desirable future direction for driver assistance systems was determined.

The effects of the additional visual and auditory stimuli on the loudness evaluation of road traffic noise was investigated by the method of magnitude estimation. As a result, it was shown that additional visual stimulus of noise barrier can influence on the loudness perception of road traffic noise. Also, additional auditory stimuli such as green music or sound of flowing water can influence on the loudness perception of road traffic noise, approximately 5~10% lower than the absence of stimuli. But this effect was disappeared in the range of over 65dB(A).

Purpose: The purpose of the study was to investigate the status of visual health behavior of school-age children and to identify the predicting variables of the school-age children's visual health behavior. Method: The subject was 764 children in grades 4 to 6, enrolled in 2 elementary schools located in urban area. The data were analyzed using t-test, ANOVA, correlation analysis, and stepwise multiple regression. Result: The findings were as follows: 1. The mean of the score of the visual health behavior of school-age children was 41.59(SD=7.22) and there was a significant difference according to grade. 2. There were significant correlations between visual health behavior and self-efficacy for visual health behavior (r=.51, p=.000), motivation for visual health(r=.45, p=.000), perceived benefits(r= .34, p=.000), self-concept(r=.32, p=.000), knowledge of visual health(r=.30, p=.000), health perception for vision(r=.16, p=.000), health locus of control(r=.11, p=.002), and perceived barriers(r=.-.12, p=.000). 3. Self-efficacy for visual health behaviors, knowledge of visual health, motivation for visual health, self-concept, health perception for vision, and perceived benefits were identified as predictor variables of the visual health behavior of the school-age children from the stepwise multiple regression analysis. The total percent of variance accounted by these 6 variables were 36.9％. Conclusion: From the result, it is suggested that the development of comprehensive visual health education program including the component of self-efficacy, health motivation and self-concept to promote the visual health of school-age children.

Extracting primitives from imagery plays an important task in visual information processing since the primitives provide useful information about characteristics of the objects and patterns. The human visual system utilizes features without difficulty for image interpretation, scene analysis and object recognition. However, to extract and to analyze feature are difficult processing. The ultimate goal of digital image processing is to extract information and reconstruct objects automatically. The objective of this study is to develop robust method to achieve the goal of the image processing. In this study, an adaptive strategy was developed by implementing Gabor filters in order to extract feature information and to segment images. The Gabor filters are conceived as hypothetical structures of the retinal receptive fields in human vision system. Therefore, to develop a method which resembles the performance of human visual perception is possible using the Gabor filters. A method to compute appropriate parameters of the Gabor filters without human visual inspection is proposed. The entire framework is based on the theory of human visual perception. Digital images were used to evaluate the performance of the proposed strategy. The results show that the proposed adaptive approach improves performance of the Gabor filters for feature extraction and segmentation.
