For video reality improvement, there has been much advancement in the methods of providing visual, auditory, and tactile information. On the other hand, there is little research on olfaction for video reality because it is difficult to define and knotty to manipulate. As a first step for video reality improvement using olfactory information, this research investigated users' acceptability of smell when they watch videos of various kinds and then classified the video clips based on their acceptability of different criteria. To do so, we first selected three questions of whether the scene in the video appears to have an odor (odor presence), whether a matching odor is likely to improve a sense of reality (effect on sense of reality), and whether s/he would like a matching odor to be present (preference for the matching odor). Then after collecting 51 video clips of various genres that would receive either high or low ratings for the questions above, we had participants to watch the videos and rate them for the above three questions on 7-point scale. For video classification, we paired each two questions to construct 2D space to draw scatterplot of video clips where the scales of the two questions represent X or Y axis. Clusters of video clips that locate at different quadrants of the 2D space would provide important insights in providing olfactory information for video reality improvement.

Perception refers to the process of acquiring all the information about the environment through various sensory organs such as the visual, auditory, tactile, and olfactory senses and integrating and interpreting the information transmitted to the brain. The ability to use these perceptions efficiently is called perceptual skill, and perceptual skill is an important factor for improving performance in the field of sports. As a result, many researchers have developed various perceptual training programs to maximize these perceptual skills while they have also progressed on attempting to verify their effects. The perceptual skill training introduced in this study is a training method that focuses on visual perception and is a training method that is applied in the United States and Europe. to improve sports performance. As a result of carrying out the perceptual skills training based on the kicker's important clue (the kicker's hip - the angle of the body and foot before kicking) to the goalkeeper in the situation of a soccer penalty kick improved the ability of predicting the direction of the ball while even in tennis, carrying out the perceptual skills training based on the server's important clue (position, ball, racket) improved the accuracy of the ability to predict in the direction of serve. Recently, there have been numerous research studies that were carried out on such perceptual skills training, but the number of studies conducted are insufficient, especially in Korea where research studies on perceptual training seem to be in a relatively neglected state. In addition, extensive studies need to be carried out to investigate whether the improvement of perceptual skills in the laboratory situation can be transitioned to an actual performance situation. Therefore, in order to elevate sports performance, researchers need to examine the perceptual training program's extent of necessity as well as the research direction regarding its effects.

This is an analysis study about the pictorial frame of Georges Schwizgebel's animation "The Subject of Picture", focusing on Deleuze's frame theory. First of all, the shapes in the frame of the animation is the representation of the tactile sensation from the erased vestiges of the characters. It shows the metamorphosis of the erased vestiges of the shapes by Deleuze's sensibility theory. Besides, the layout of the animation's background has similar property with the aplat which was mentioned by Deleuze. It means that the background of the animation correspond to the aplat which is other boundary different from reality, and the character which has the minimum embodiment about the object makes the shape newly through the distortion of the shape. Secondly, as the problem of frames in terms of the continuity of time, the meaning in Schwizgebel's animation is created by the relation between each frame. It means that the depiction of the shape itself by the composition between each frame is composed of the frame. Eventually, Schwizgebel's work is the animation which has the characteristic of the modem cinema and is the crystal depiction that deviates from rules and logics of the object which was mentioned by Deleuze.

Research data means data in the form of facts, observations, images, computer program results, recordings, measurements or experiences on which an argument, theory, test or hypothesis, or another research output is based. Data may be numerical, descriptive, visual or tactile. Scientific research is changing because of the paradigm shift. It is all being affected by the data deluge, and a data-intensive science paradigm is emerging. Hence, paradigm shift in scientific research led to increase of value and importance of scientific data. Essential to the creative research and development for scientific data can be reused efficiently is the sharing and utilization of establishing management system. Establishing of management system for sharing and utilization of scientific data should be done at the national level, but compared with Europe, Australia, the United States, China, the management system of Korea doesn't have not linkage or efficiency or internal stability. Australia, the United States, China continues to expand a Mid- and Long-Term policy making, legislation, its investment in infrastructure, so as to promote the utilization of data, such as collection, management and maintenance of scientific data through the relevant agencies at the national level. This study consider legislation cases and management policies of the above countries to the end to that establish management system for the efficient and fair sharing and utilization of scientific data and the legal system, and that provide scientific data legislation and policies related to the future of our country.

Since the 20th century, it was often announced that a painting was dead, but it is still alive. Even in the epoch of recently increasing virtuality, painting is still appealing, consistently pursed by many with a thirst. Thus, it is said that the mission of a picture is to maintain its reality without being trapped in virtuality. In the history of Western painting spanning over several hundreds of years the myriad of techniques and styles have emerged, going though a huge variety of changes: namely, its not possible any longer to find the new ways of expression in painting. Hence, painters today feel that it becomes more gradually difficult for them to execute something. In the midst of swiftly changing, diversely evolving trends of contemporary art, the painters incessantly pose a question why they go on working on painting, and seek to find its answer. Why the painters still try to say something about painting? Is that because they consider it the quintessence of fine arts or think that it is in no way possible or meaningful to comment on fine arts without relying on painting? If then, is there any avenue of escape for the painting? The question of the 'crisis of painting' is still raised, when reviewing the rapidly changing conditions of inventing artworks. That is also why the recent works failed to offer a conceptually unified, universally shared perspective of painting. Moreover, painting is left to shrink comparatively with the pervasive existence of videos and installations briskly employing digital images and technologies in their creations. Whats more problematic is the fact that there is a growing sense of crisis not only in the sphere of painting hut also in the entire realm of art. As the organizers and curators of big-scale exhibitions and art projects tend to exploit their space spectacularly, focusing primarily on their abilities to control the space, there is a pervasive notion amongst them that painting is a medium that is not properly to suit such purposes and requests. Today, the death of painting is, in fact, the death of modernist painting, which assumed a central role in the history of art for a considerable amount of time, rather than the death of painting itself. Employing a new paradigm of invention, a picture is now entering a new domain which is perhaps unknown to us. Moving beyond the stereotypical concepts of painting, physical property and flatness, pictures today reveal the introduction of time and space and the penetration of new media such as installation, photography, video and the Internet. Despite such trends, the dexterity and tactile capability of painters is still to be considered significant in the future. The renewal of painting is made in an entirely unexpected manner and place.

Traditional computer simulation uses only traditional input and output devices. With the recent emergence of haptic techniques, which can give users kinetic and tactile feedback, the field of computer simulation is diversifying. In particular, as the virtual-reality-based surgical simulation has been recognized as an effective training tool in medical education, the practical virtual simulation of surgery becomes a stimulating new research area. The surgical simulation framework should represent the realistic properties of human organ for the high immersion of a user interaction with a virtual object. The framework should make proper both haptic and visual feedback for high immersed virtual environment. However, one model may not be suitable to simulate both haptic and visual feedback because the perceptive channels of two feedbacks are different from each other and the system requirements are also different. Therefore, we separated two models to simulate haptic and visual feedback independently but at the same time. We propose an adaptive mass-spring method as a multi-modal simulation technique to synchronize those two separated models and present a framework for a dual model of simulation that can realistically simulate the behavior of the soft, pliable human body, along with haptic feedback from the user's interaction.

This study was done to understand nonpharmacologic pain management for pediateric patients and nurses' knowledge and attitudes toward it. The aim of this study was that which method did the patient's use according to the nurses' age, and how did they effectively use these methods in their field. The subjects of this study were 77 nurses working in the Pediatric unit in the Kyung Medical Center from September 2 to 15, 1999 using questionnaire form. The results of this study were as follows : 1. We divided the subjects into four groups : Younger than one year old, 1-6 years, 6-12 years, 12-18 years group. In the group younger one year old, most of the nurses participating in this study used speaking in soft quiet tones, supportive touch, toys, pacifiers. In the group of 1-6 years, they used speaking in soft quiet tones, toys, distracting attention, story talking, and visual stimulus. In the group of 6-12 years. they used pop-up books, providing information, cold therapy, speaking in soft quiet tones, supportive touch. In the group of 12-19 years, most of them used providing information, controling respiration and supportive touch. 2. The effective nursing intervention used in their field are speaking in soft quiet tones, pacifiers and nesting with blanket in the group of younger than one year old. Un the group of 1-6 years old, speaking in soft quiet tones, toys, and supportive touch were effective method in the control of nonp-harmacologic pain management. In the group of 6-12 years old, story talking, supportive touch, and speaking in soft quiet tones were effective method and in the group of 12-18 years old, providing information, cold therapy and supportive touch were effectively used to control nonpharmacologic pain management. 3. To compare the general characteristics and non-pharmacologic pain nursing intervention, in the group of younger than one year, touching stimuli is widely used. In the groups of 1-6, and 6-12 years old, visual and audio method were widely used. In the group of 12-18 years old, sensitive intervention were used as well as education, information and guided imagery. In conclusion, there was no significant difference in nurses' demographic characteristics, child's age and nonpharmacologic pain management. There was significant difference only in the nurses working area, that is nurses working in the surgical department used more audio-visual-tactile pain management methods than medical department.

For the successful endodontic treatment, root canal should be cleaned thoroughly by accurate mechanical and chemical canal preparation and sealed completely with canal filling material without damaging the periapical tissues. The accuracy of the root canal length measurement is a prerequisite for the success of the endodontic treatment, and the root canal length is often determined by the standard periapical radiographs and digital tactile sense. In this study, the accuracy and the clinical usefulness of Digora/sup (R)/, an intraoral digital imaging processor and the conventional standard radiographs were compared by measuring the length from the top of the file to the root apex. 30 single rooted premolars were invested in a uniformly sized blocks and No.25 K-file was inserted into and fixed in each canal. Each block was placed in equal distance and position to satisfy the principle of the bisecting angle and paralleling techniques and Digora/sup (R)/ system's image and standard periapical radiographs were taken. Each radiograph was examined by 3 different observers by measuring the length from top of the file to the root apex and each data was compared and analyzed. The results were as follows; 1. In the bisecting angle technique, the average difference between the Digora/sup (R)/ system and standard periapical radiograph was 0.002 mm and the standard deviation was 0.341 mm which showed no statistically significant difference between the two systems(p>0.05). Also, in the paralleling technique, the average difference between these two system was 0.007 mm and the standard deviation was 0.323 mm which showed no statistically significant difference between the two systems(p>0.05). 2. In Digora/sup (R)/ system, the average difference between the bisecting angle and paralleling technique was -0.336 mm and the standard deviation was 0.472 mm which showed a statistically significant difference between the two techniques(p<0.05). Also, in the standard periapical radiographs, the average difference between the bisecting angle and paralleling technique was 0.328 mm and the standard deviation was 0.517 mm which showed a statistically significant difference between these two techniques(p<0.05). 3. In Digora/sup (R)/ system and the standard periapical radiographs. there was a statistically significant difference between the measurement using the bisecting angle technique and the actual length(p<0.05), But there was no statistically significant difference between the measurement using the paralleling technique and the actuallength(p>0.05). In conclusion. the determination of the root canal length by using the Digora/sup (R)/ system can give us as good an image as the standard periapical radiograph and using the paralleling technique instead of the bisecting angle technique can give a measurement closer to the actual canal length. thereby contributing to a successful result. Also. considering the advantages of the digital imaging processor such as decreasing the amount of exposure to the patient. immediate use of the image. magnification of image size. control of the contrast and brightness and the ability of storing the image can give us good reason to replace the standard periapical radiographs.

In order to prepare kimchi tablet(K7), the kimchi was fermented with crushed materials and lactic acid bacterial starter. The effect of raying methods (hot air-drying : HAD, freeze drying: FD), moulding pressure (100, 150 and 200 kg/cm2) and moulding time (0, 1, 2, 3 and 4 min) of kimchi tablet on residual solid, characteristics of filtrate, color, textual properties, hygroscopicity and sensory quality were investigated. No great difference showed in residual solid of the tablet prepared with freeze dried kimchi (FD-KT), but the tablet prepared with hot air-dried kimchi (HAD-KT) decreased markedly with an increase in moulding pressure. Residual solid of FD-KT was lower than that of HAD-KT. The pH and redness for HAD-KT and FD-KT were similar. Total sugar. acidity and lightness of FD-KT as compared with HAD-KT were higher, while higher max, yield, strength and hardness were found for HAD-KT. Color, tactile, flavor, chewing taste, acceptability and hygroscopicity of FD-KT were generally higher than those of HAD-KT. Hygroscopicity of HAD-KT decreased with an increase in moulding pressure in md time, but that of FD-KT increased. Overall qualities of FD-KT and HAD-KT showed best in 200 kg/㎠ of moulding pressure, 3min of moulding time.

The purpose of this study was to evaluate thermal properties of soccer wear with different materials and designs. As a beginning step, the questionnaire survey about the actual condition of soccer wears was conducted. with the results of the questinnaire, two soccer wears with new material and design that were improved in tactile sensations, absorption and ventilation were developed. We evaluated thermal and subjective responses of subjects wearing Korea national soccer team uniform in 1998 World Cup (Uniform 98), soccer wear with new material and same design(New II) and with new material and new design(New I). New I was made with mesh in armhole for improving ventilation. Rectal temperature, skin temperature, clothing microclimate, and heart rate were measured in climatic chamber test(twelve times) and field test(eighteen times). The results were as follows. 1. As the results of the climatic chamber test, rectal temperature was lower in New I and New II than Uniform98, and mean skin temperature was lower in New I than Uniform 98 and New II. Heart rate was lower in New I than New II, and total body weight loss and local sweating were not significantly different by soccer wears. 2. As the results of the field test, rectal temperature was lower in New I than Uniform98 and New II. Mean skin temperature was lower in New II than Uniform98 and New I. Clothing microclimate temperature was lower in New II than Uniform98 and New 1, and clothing microclimate humidity was lower in New I, New II than Uniform 98. Heart rate was lower in New I than Uniform 98, New II and total body weight loss and local sweating were lower in New I, New II than Uniform 98. In conclusion, New I using new design using mesh in armhole and new material using sweat absorbent finishing was excellent from the point of view of physical responses, ventilation and sweat absorption.
