백내장은 카메라의 렌즈에 해당하는 우리 눈의 수정체에 혼탁이 생겨서 빛이 잘 통과하지 못하는 질환으로 시력저하, 눈부심, 대비감도(다른 세기의 빛을 구별하는 시각능력) 저하, 색각(색채 식별하는 감각)감퇴 등을 유발하는데, 당뇨병환자에서의 백내장에 대해 알아보자.

사진을 결정하는 것은 노출 구도 초점 이라 했다. 이 3박자가 완벽하게 되면 정말 좋은 사진을 만들 수 있다. 구도와 초점은 정해진 법칙이 있어서 누구나 쉽게 배울 수 있고 선천적으로 감각을 타고나기도 하지만 노출만큼은 누구도 쉽게 가르쳐줄 수 없을 정도로 정말 영원한 숙제이다. 이것을 해결하는 방법은 열정을 가지고 정말 끊임없이 사진에 시간을 투자하여 많은 사진을 찍어봐야 한다. 노출 구도 초점에다가 '빛'을 보는 시각을 익힌다면 그야말로 자기만의 독특한 작품을 만들어 낼 것이다. 이번호에서는 빛의 방향에 따른 빛의 종류를 알아보도록 하겠다.

야경사진은 자연광 일색인 일상의 낮과는 달리 인공광과 자연광이 함께 어우러져 있는 밤의 풍경을 표현한다. 특히, 야경사진은 빛을 어떻게 효과적으로 이용할 것인가라는 문제에서 한 발 더 나아가 얼마만큼의 빛을 받아들일 것인가를 고민하게 하는 촬영이다. 바로 이 문제는 노출시간으로 연결되며 조리개 값을 실정하게 한다. 더불어 작가의 낭만적인 미적 감각을 함께 표현할 수 있는 촬영방법이다.

The aim of this study was to analyze the effect of different sensory information on the motor function which is resulted from visual stimuli. Particularly, it was focused on the effect of complementary color stimuli on reaction time. Twenty volunteers(10 men & 10 women), between the age of 20 and 25 yearn participated in this experiment. Experiments were carried out in a light & sound-attenuated chamber, and the overall system consisted of a PC. interface card. LEDs. key board switch, and display panel. Although many measurements of sensory-motor integration has been studied the quantitative analysis of sensory-motor integration has not been developed well. Quantitative analyses were performed to investigate the effect of the different sensory information on the arm motor system in the point of view sensory-motor integration. The result showed that the reaction time for visual stimuli of complementary colors was faster than that under same color environments : and, in same color environments and the reaction speed was varied inversely with respect to the magnitude of the light wavelength.

우리 주변에는 항상 다양한 색채들이 존재하고 있으며 이 색채 안에서 살아가고 있다 또한 생체는 늘 빛을 요구하는데 빛의 강약이나 색채에 의하여 나타나는 감성 변화를 객관적으로 나타내고자 하는 연구가 오래 전부터 있어 왔다. 다양한 색채가 인체에 미치는 영향에 대해서는 심리학분야에서 정성적으로 보여지고 있으며. 색채심리학의 한 분야로서 감각기관의 기능분석에 관한 연구들이 일부 진행되었고 기초의학분야에서도 그 치료효과는 검증이 안 되었으나 점차로 응용하고 있는 실정이다.(중략)

In contemporary society, spa has become one of the important healing spaces. As the present urban life has been more and more complex and competitive, space of recreation and healing are dramatically increased in terms of its number as well as location. In the past, there were three kinds of spa visitors. The first was the people who visited spas for medical reasons. The second was the people who visited spas for leisure and refreshment. The third was for social gatherings like in the ancient Rome. In present time, these three reasons are mixed together. As the spa program became rich and various, visitors tends to seek an appropriate spa environment that suits their needs. This is the main background for contemporary spa designs. In any case, concept of healing has been always the core element in spa. Light and sense have vital role to make a unique spa design. This paper aims to study different light and sense applications in contemporary spa designs. Specific focus is to find how light and sense in spa designs act to create a healing environment. 4 spa projects built in Europe after 2000 were selected and were analyzed based on the 4 light and sense characteristics. In conclusion, case analysis was summarized to suggest future possibilities.

Photodynamic therapy is one of the ways to treat cancer using light and during laser irradiation, photosensitizers react and combine with oxygen to destroy cancer cells. This treatment is in the spotlight as a treatment that minimizes side effects in cancer patients. Among them, photosensitizers differ in the treatment area, treatment effect, and degree of absorption depending on the type. Therefore, in this study, a quantitative evaluation study was conducted on the effect of inhibiting cancer cell proliferation by irradiating blue LEDs on HELA cell lines injected with 5-ALA among photosensitizers.

The TUI system Modeling Language(TML) developed in this research can be used for designing TUI system with concerning about TUI's characters. For design to be concerned about physical property of tangibles and control device and digital media, TML can be a framework to give a definition of each property and be used for designing action and reaction process separately. And it would be the guideline to represent interaction's dynamic property through showing parallel information flows among objects. Finally, for verification TML's suitability, TUI system to which TML was applied was developed.

Objectives: Eyeblinking varied depending on individual cognitive abilities or personality traits thought to related to brain mechanisms of sensory modulation. This study explored whether personality traits are related to the rate of eye blinks and how eyeblink and evoked potential augumenting-reducing(EPAR) interact Methods: Forty four students were studied with EPAR topography to explore how eyeblinks, personality and EPAR interact The Zuckerman Sensation Seeking Scale(SSS) and Eysenck Personality Questionnaire(EPQ) were used as personality measured by a stimulus response program during EP study. Results: Rate of blink increased as intensity of light increased. The General(GEN), Thrill and Adventure Seeking(TAS), Experience Seeking(ES) and Disinhibition(DS) subscales in SSS and Extraversion-Introversion(E) subscale in EPQ showed significant negative correlations with number of eyeblinks in the hightest intensity of light, whereas Neuroticism(N) subscales in EPQ showed a positive correlation. Correlation between number of eyeblinks with the brightest light and EPAR slope varied topographically. The strongest positive correlation was noted in right posterior temporal area. Conclusion: High sensation seekers blinked significantly fewer times than lower sensation seeker did. Higher personality correlations with eyeblink than with EP may imply that the eyeblink works as a primary filter since it is more directly related to central mechanisms of sensory modulation than EP. The right posterior temporal area may play an important role in modulation of visual stimuli.

Stage art basically builds upon the essence of "seeing," and at the same time, possesses relativity in showing and seeing. Stage lighting uses artificial light to solve the essence of "seeing", which is the foundation of stage art, and coming into the modern age, its role has been enhanced to an important medium for visual expression in stage art, due to the lighting tools that developed at a rapid pace along with the discovery of electricity, as well as the development of optics. Therefore, not only does lighting use a medium known as light in a field of stage art that gives mental and emotional inspiration to the audience, and aesthetically expresses time and space. In other words, stage lighting is a complex function of light engineering (technology and science) and aesthetic sense (feeling and art). This study aims to do research on methods for the visualization of stage space through lighting, mainly focused on dancing. I have studied the basics of stage lighting, its relations with other fields of stage art, and the functions and characteristics of lighting. Results show that lighting could be used to maximize the visualization of dancing and emphasizing the artistic growth of lighting and its ability to aesthetically express and I came to the following conclusions. First, lighting uses the forms and directions of light that various tools are able to produce in order to visualize the space on stage, and can maximally express the image that the work seeks. Second, it is possible to use lighting, through the movement of light, as a visual representation of the configuration of space in dancing works. Third, through the expression of visual and spatial aspects created by light, the work's dramatic catharsis can bring out mental and emotional feelings form the audience. Fourth, lighting can be seen not as a supporting role, but as an original visual design. To conclude, in order for lighting to be freed form the simple function of "lighting up the stage," which a majority of people think is common knowledge, and grow as one area in art, lighting designers must understand the intentions of the choreographer and the work with creativity and artistry they must consider light and color as an aesthetic language in order to heighten the effects of the work and allow it to partake as one element of work creation, so that lighting will be treated as a form of art.
