  • 본 연구에서는 문제 해결 전략에서 시각적 조직화와 협동학습의 효과를 조사하였다. 고등학교에서 세학급 (N=127)을 선정하여 시각적 조직화를 이용한 문제 해결 전략을 개별적으로 사용하는 집단(SV), 협동학습 환경에서 사용하는 집단(SVC ), 그리고 통제집단으로 배치하였다. 수업 처치 후 객관식 문제 해결력, 전략 수행 능력, 화학 학습에 대한 불안, 수업참여도, 학습 동기를 조사하였다. 연구 결과 객관식 문제 해결력에서는 집단간 차이가 유의미하지 않았으나, 전략 수행 능력에서는 수업 처치의 주효과가 나타났다. SV 집단과 SVC 집단의 점수가 통제 집단보다 높았으며, 특히 하위 영역 중 문제 이해와 관련 법칙 회상에서 높은 점수를 보였다. 수업 참여도와 학습 동기 검사에서도 SV 집단과 SVC 집단의 점수가 통제 집단보다 유의미하게 높았다. 그러나 시각적 조직화를 이용한 문제 해결 전략이 학생들의 화학 학습에 대한 불안을 유의미하게 감소시키지는 못했다.

  • Perceiving the depth of space in the spatial organization of architecture is perceiving spaces as well three dimensions as the fourth dimensions -perceive the time-. Physical depth in architectural space differs from perceptional depth in aspects of not only dimension but also perceptional effects. In this study, the perceptional depth is defined as visual depth and physical depth is depth of space. These purposes of this study are classifying the perceptional effects of visual depth -visual access, sense of variety, dynamic and cubic effect... - and the methods of spatial composition which causes visual depth in architectural space.

  • A new system for automatic scoring of 'organization' of the EEG dominant rhythm was constructed and applied to 18 normal subjects and 15 patients. Organization parameters which best represented the 'organization' as judged by 5 neurologists' visual inspection were calculated and the automatic organization scoring was obtained by a linear regression of those organization parameters. Furthermore, values of the regression coefficients were used to study the characteristics of EEG interpretation by each neurologist, and this scoring technique can also be applied to the training of EEG interpretation.

  • 입체 시각 피로는 3D 영상의 확산을 방해하는 가장 주된 요인으로 알려져 있다. 입체 시각 피로는 수렴과 조절의 불일치에 의하여 유발되는 것으로, 이 현상은 양안 시차를 포함하는 영상을 3D 디스플레이로 제시하는 경우 자극에 의하여 유발된 수렴 거리가 물리적인 조절 거리와 불일치하여 발생한다. 이는 실감을 증진시키기 위하여 입체 자극을 사용하는 경우 언제나 입체 시각 피로를 유발할 가능성이 있음을 의미한다. 따라서 입체 시각 피로를 감소시키기 위하여 직접적인 원인을 제거하려는 노력뿐만 아니라 이를 간접적으로 감소시키기 위한 노력 역시 필요하다. 이런 관점에서 본 연구는 입체 시각 피로에 영향을 미칠 가능성이 높은 상대적 시차, 시청 거리, 시청 방위 요인이 주관적 입체 시각 피로에 미치는 영향을 측정하고 입체 시각 피로를 최소화하기 위한 각 요인의 수준을 알아보고자 하였다. 그 결과 참가자들이 입체 시각 피로를 보고하는 경우는 상대적 시차의 교차 시차 크기가 7분 22초를 넘어설 때, 그리고 수직 시야각이 15도 보다 클 때라는 것을 확인하였다.

  • The purpose of this thesis is to classify landscape-type of golf course, and t provide a better understanding of landscape of existing golf courses, seek a developed method for landscape, and other useful knowledge. In order to classify landscape type of the golf course, and analyze the preference for the determinants, we have selected 4 golf courses in Yongin, Kyonggi Province. The analysis in this study shows that a variable, 'familiarity' is the most potent influence of visual preference, (Sig 0.01), and it can be divided into five classes of landscape-type in golf course. More specifically, we conducted the analysis of the image of views and visual preference to bring out major factors which could decide visual preference in golf courses. The results between visual preference and physical variable are as follows; 1. It implies that a factor for a image of the view in golf course is analyzed by 4 districts from factor 1 to factor 4. An ability explaining those factors in the whole of variable quantity is 51.742%, implying factors for the image of the scene in golf courses are appeared as familiarity, changeableness, spaciousness, and naturalness. Among those factors, since familiarity(C.V.; 26.783%) and changeableness(C.V.; 112.200%) took high rank, this represents the fact that familiarity or changeableness highly affects the forming of image. 2. Defending on degree of image ability in golf course, we could classify as five types such as Type I, Type II, Type II, Type IV, and Type V. 3. As a result of calculating type of factor score, Type I had the lowest ranking in naturalness, and rather lower than others such as organization and spaciousness. The II is a top-ranked one in familiarity and naturalness, while it has the lowest ranking in spaciousness. Type III has the highest ranking in organization and preference. Type IV is the lowest-ranked one in familiarity and preference. Type IV is the lowest-ranked one is familiarity and preference. Type V has the highest ranking in spaciousness, but the lowest ranking in organization. 4. As a result of preference, Type III, Type II, Type V, Type I, and Type IV come out in order. That water-seen place type charges the highest rank shows the importance of changeable materials. 5. These factors-familiarity, organization, spaciousness and naturalness- are the major materials of the scene of view in golf courses. The possibility of how to use those for designing and making enhanced golf courses should be reinvestigated through these factors. Especially, it is acknowledged that the duction of changeableness, which is not mentioned in the study of informational approach, is much stimulating for the designing use. A further research on this theme should be made in the future, not limiting to the golf courses in Yongin.

  • Multi-sensory systems, including the visual, somatosensory, and vestibular ones, are involved in maintaining standing balance. The organization of these sensory systems is as important as the efficiency of each individual system in maintaining optimal balance. The purpose of the present experiment was to investigate the developmental changes in static standing balance and sensory organization under altered sensory conditions. This study involved 64 children (from 4 to 15 years of age) and 17 young adults. The children were divided into four age groups: 4~6, 7~9, 10~12, and 13~15 years. Static standing balance was assessed with the one-leg standing test under four different sensory conditions: the children stood on a firm surface with (1) eyes open or (2) closed, and they stood on a foam surface with eyes (3) open or (4) closed. In balancing ability, the age groups exhibited significant differences. The function of sensory organization for balance control was poorer for the children than for the young adults. The functional efficiency of the somatosensory system of the children aged 7~9 years was at the young adults' level, and the visual function of the children aged 10~12 years had also reached the young adults' level. However, the functional efficiency of the vestibular system of children was significantly lower than that of the young adults, even at the age of 15 years. This may indicate that sensory organization and standing balance are still developing after the age of 15 years.

  • We have analysed the use and organization of space in the Centres des Documentations et de Informations(CDI) in lycees in France with the equivalent information centres. The majority of CDI are located in close proximity to the Academic staff and provide easy student access. The CDI provide not only books but also reviews, magazines and CD-Rom. This information is very important to pupils both in the pursuit of their higher studies and also with their future professional life as there is also careers information available to be discussed regularly with the careers advisor. The function of the CDI is not only to provide information. As part of the curriculum there are classes on how to access the information available in the CDI as well as Seminars and Audio-Visual courses. This management makes it possible for the CDI to operate, not only as a school library but also as a multi-function centre of documentation and information; a variety of spaces are also available: a room for private/small group study. A computer room (as well as a research corner), a reading room, monthly review room, photocopy room, rest room, exhibition room, careers information room, audio visual room etc. The results of this study can be used as essential information during the space planning of Korean school libraries in the future.

  • When we put a construction on the space organization form of Seyeon-jong garden through a consequence of drawing analysis, we were able to certify that a certain space construction principle was applied as following. First, the arrangement and organization of space construction element embodied systematic order y clearing the character of space, and heightening the degree of cognizance with the means of functionability, scale, height, decorationability, an inclination of artificiality and nature, systemetic approchability. Second, the space construction element of Seyeon-jong garden pursued a harmony of human work and nature for creating a various atmosphere and visual quality. Third, Seyeon-jong garden constructed the space by establishing the measurement of human scale that introduced a conception of near, middle, distant view on the visual angle. Forth, Yun go san introduced the natural shape of 'The song of five friends' as a construction element, and represented the symbolism that he had seeked for throught he arrangement method, christening, composing technique of the space construction element for expressing ideal space which is described in 'The four season song of fishermen' spatially at Seyeon-jong garden. As the results of this study, that Yun go san created his own ideal space that he longed for at Seyeon-jong garden with applying fixed design system, and he realized his will that he strived to form a complete whole in perfect harmony.

  • 본 연구에서는 웹사이트 인터페이스의 여러 디자인 문제 가운데 사용자의 감성적·심미적 만족을 주요 목표로 하는 스타일의 역할을 이해하고 다양한 시각 요소에 기초한 분석적 접근 방법을 제시하였다. 스타일은 정서, 문화적 동질감 및 메시지를 즉각적으로 드러나게 하는 맥락을 제공하며 재미와 몰입감을 주는 역할을 한다. 이는 웹사이트 인터페이스 디자인의 우선적 디자인 목표라 할 수 있는 인지적 측면의 디자인 원리에 따른 기능성과 동시에 각종 시각 요소들을 통해 구현해야 할 주요 디자인 특질이라고 할 수 있다. 웹사이트 인터페이스의 시각요소를 파악하기 위해 내용의 구조에 따른 구성 측면, 심볼 시스템에 관한 매체 측면 및 조형적 측면의 여러 다른 차원으로 구분하였다. 여기서 도출된 시각 요소들에 기초하여 스타일 형성의 요인들을 분석하였다. '소프트-하드(Soft-Hard)', '따뜻한-차가운(Warm-Cool)'을 각 축으로 하는 이미지맵의 반대편에 위치하는 몇 개의 사이트를 선정한 후, 구성적 측면의 요소들에 대한 조형적 특성과 아이디어를 전달하는 시각적 전달방식에 따른 정서적 효과를 파악하였다. 웹사이트 스타일에 대한 이 같은 분석적 접근 방법의 이해는 디자인 계획시 디자인 문제의 체계적 이해와 다양한 해결안 도출에 활용될 수 있으며, 화면디자인을 위한 구체적 가이드라인을 마련하기 위한 토대가 될 수 있다.
