This study has analyzed the features of attention to spacial composition seen in "Seeing ${\leftrightarrow}$ Seen" Correlation of continuous move in the space. The eye-tracking was employed for collecting the data of attention features to the space so that the correlation between visual perception and space could be estimated through the attention features to the difference between spacial composition and display. First, it was confirmed that the attention features varied according to the structure of shops and the exposure degree of selling space, which revealed that, while causing the customers' less attention to both sides of shops, the vanishing-point structure characteristically made their eyes focused on the central part. Second, their initial observation activities were found to be active at the height of their eyes. Third, 10 images were selected as objects for continuous experiment. There was a concern that the central part of each image would be paid intense attention to during the initial observation, but only two of those were found to be so. Fourth, there had been a study result of eye-tracking experiment that the attention had been concentrated on the central part of the image first seen. This study, however, revealed that such phenomenon is limited to the first image. Accordingly, it is necessary to draw up such method for ensuring reliability in order to use the data acquired from any eye-tracking experiment as exclusion of the initial attention time to the first image or of unemployment of the initial image-experiment to analysis.

비냉각형 적외선 검출기를 사용한 적외선 열상 카메라의 영상은 다이나믹 레인지가 좁고 신호 증폭에 의한 노이즈로 인하여 피사체를 식별하기 어려운 단점이 있다. 인간의 시각모델을 기반으로 한 레티넥스 알고리즘은 콘트라스트 향상 및 컬러 재현성에 있어서 매우 효과적인 방법으로 알려져 있다. 하지만, 적외선 열상 이미지와 같이 다이나믹 레인지가 좁은 영상에 레티넥스 알고리즘을 적용할 경우 오히려 콘트라스트가 감소하고 이미지 품질이 저하된다. 본 논문에서는 적외선 열상 이미지의 특성에 적합한 레티넥스 알고리즘 기반의 화질 개선 방법을 제안한다. 콘트라스트 개선 성능을 향상시키기 위해 새로운 다이나믹 레인지 압축 함수를 사용하였고, 국부적인 윤곽과 노이즈를 개선하기 위해 콘트라스트 보상 처리를 영상의 합성 과정에 적용하였다. 실험 결과 영상의 비교와 분석을 통해 제안한 알고리즘이 기존의 알고리즘보다 적외선 열상 이미지의 화질 개선에 더 효과적인 방법임을 확인하였다.

The purpose of this research is to develop a safe and convenient wearable technology wear for bikers. For this, we studied the current usage of two-wheeled vehicles and have also researched the rate of accidents and its causes. We then used them along with previous studies in terms of visual perception as factors to decide the crucial elements of the riders' apparel. Case studies and the break down for the established prototypes for bikers were practiced as well. Based on this process, a survey was conducted to find out the needs of the bikers in the areas of both apparel and technology and then proceeded to produce the appropriate design and device modules. In the apparel sector, the result of the survey indicated that it was considerable that any digital devices were not shown to sustain a natural visible look. It also was essential that the materials were durable and made for safety and easy movement. In the digital function sector, it was significant that a motion input interface which will be embedded into the wear was needed to avoid any dangerous situations. This would ensure the safety of not only the rider but the surrounding riders as well. Lastly, protecting the rider's skin from any harmful elements was regarded necessary as well. Based on these requirements, a new prototype was created and will be tested if the requirements stated above are all met and will be evaluated according to the effectiveness of its functions.

Purpose: This study aims to investigate the effects of a group computerization cognitive rehabilitation program on cognitive function in patients with cognitive impairment. Methods: The subjects of this study comprised 34 patients with cognitive impairment (15 males and 19 females) who were randomized into two groups. The experimental group (n = 17) were trained with the group computerization cognitive rehabilitation program, while the control group (n=17) received traditional cognitive therapy. The interventions for both groups were performed for 1 hour per day, once a week for 12 weeks. The cognitive functions of the subjects before and after the experiment were measured using the Korean mini-mental state examination (K-MMSE), global deterioration scale (GDS), clinical dementia rating (CDR), and Lowenstein occupational therapy cognitive assessment (LOTCA). A paired t-test was conducted to examine the intragroup differences before and after the experiment, and ANCOVA was performed to check intergroup differences. Results: The intragroup comparison results showed that the cognitive function of the group that were trained with the group computerization cognitive rehabilitation program improved after the experiment more than for the group that received traditional cognitive therapy. The intergroup comparison results showed significant differences in orientation, visual perception, and visuomotor organization between the two groups. Conclusion: The results of this study confirmed that the group computerization cognitive rehabilitation program was more effective in improving cognitive function than the traditional cognitive therapy in patients with cognitive impairment. Based on the results of this study, the group computerization cognitive rehabilitation program can be used as an effective intervention method for patients with cognitive impairment.

애니메이션은 제작에 있어 수용자의 지각에 반응하는 의도된 프레임 수(명멸현상)를 이용함으로써 움직임의 효과를 극대화 할 수 있다. 그러나 특정의 효과(경찰차의 경광등이나, 신호등의 점멸을 확대한 장면에서 빠른 점멸을 의도적으로 계획한 프레임 수)나 지나친 시각적 자극을 주기 위하여 배색에 있어서 채도의 대비를 높이는 경우는 매우 위험한 상황을 초래할 수도 있다. 일본의 '포켓몬스터' 방영에서 일어난 피해로 문제의 심각성이 대두된 명멸현상의 위험성은 의학용어로 '빛과민성 발작증세'로 정의되고 있다. 애니메이션의 제작에 있어서 컬러의 품질관리도 중요하지만 색채가 미치는 심리적인 요인을 분석한 컬러설정이라든가, 영상효과에 있어서 섬광과 패턴의 연속적인 점멸이 미치는 위험성을 제작단계에서 체크할 필요가 있음을 시사하고 있다. 연구자는 일본에서 사용 중인 영상 애니메이션 등의 제작기법에 관한 가이드라인을 포함, 국외의 관련규정들을 종합 검토하고 피험자를 대상으로 한 실험과 비교하여 명멸현상의 위험성에 대한 해결방안을 마련하였다.

The purpose of this study is to propose future-oriented high-rise buildings where the vehicle is parked at the top of the building. At the same time, the vehicle is used as a part of the building along with the advent of the era of autonomous driving. The suspended structure is proposed as a suitable structural system for architectural planning. This system is free to design because there are no limitations on column planning compared to conventional designs. In particular, the low-floor plan can be used as an open space because colums are not arranged in the lower-floors. Thereby opened low-floor plan has advantages that visual perception of the space is improved, noise problems along the side of the street is solved and planning underground parking spaces are easier. These advantages can solve the problem of overlapping columns with vehicle traffic in the building. However, there are some problems that the suspension structure is mainly a formal form and the usable area is small compared to the core area because it is a core-oriented structural system. In this regard, a new structural system was proposed by combining the concept of suspended structure and cable stayed column. Therefore, this paper analyzes the existing style of high-rise housing suspended Structure and proposes a new structural system and the concept of design for autonomous vehicles.

A science museum responds independently based on the exhibits and exhibition environments as the visitors are different in purposes, interests and demands. Therefore a science museum should be designed keeping it in mind that there are various ways for visitors to perceive and use the exhibition spaces and exhibits. The purpose of this study is to compare and analyze the characteristics of sensory receptors for the exhibits in National Museum of Nature and Science's Global Gallery, Tokyo, in terms of information transmission and to identify the nature of exhibit medium that can affect the perception and recognition of the exhibits by visitors. Through these 9 sensory receptors, human recognizes first with visual, auditory and olfactory senses and reacts using vestibular organ, proprioceptor (stretch), tangoreceptor, themoreceptor, taste and olfactory senses. Human uses these information processing to recolonize the external environment. This process is similar to the visitor's information transmission process for the exhibition medium. By dividing the analysis results per exhibition theme and developing the information transmission processing types per sensory receptor, we could understand that the distribution conditions are closely connected with the composition of the exhibition scenario in the exhibtion area. Especially, the understanding of how the information transmission is made through sensory receptors could can be the criteria that determines on the factors that can identify the exhibition purposes of a science museum which are eduction and understanding.

This study specifies the definition and characteristics of fake fashion by categorizing cases through an analytical framework that uses the concept of simulacre, which is one of the theories that explains the reproduction of images and symbols in a modern consumer society. The presentation stages of modern fake fashion based on Baudrillard's concept of simulacre are as follows: Stage 1 focuses on the realistic imitation of the original, Stage 2 maintains a similarity with the original while transforming through the distortion of shape or visual perception, Stage 3 is the reality of the original which has become significantly vague and actively involves the designer's creativity, and Stage 4 forms a new value and an independent aura beyond reproducing the original. The presentation techniques of modern fake fashion viewed in the concept of simulacre can be classified into optical illusions by reproduction, use of a fake object, use of unusual shapes, and re-signifying through borrowing. As a result of applying the collected cases to the analytical framework, image reproduction in Stage 1 with imitative nature is a counterfeit that cannot be regarded as fake fashion, and fake fashion in Stage 4 (that can be referred to as simulacre) is fashion with symbolic and multiple meanings with new and creative designs. Modern fake fashion analyzed in the concept of simulacre transforms or reproduces the preexisting original with the purpose of merely creating original designs as well as acts as a new symbolic signal that creates a new aura and sets a trend with a message.
