The purpose of this study is to investigate to what extent and how the infant's Object Attachment occurs. For this purpose, 28 mothers with their infants showing or having shown this phenomenon were interviewed. They were selected by the whole scale smpling method from 310 household -wives living at a delux Apt. in Seoul. The results are summarized as follows : 1. About 27% of the infants aged between 6 months and 6 years turned out to show this phenomenon. 2. Qulits, bed clothes, pillows and blankets, which infants have been closely contacted since their babyhood, were the major source of attachment objects. In general, these objects were proved to have soft, wasm, smooth, and glassy tactile sensation. 3.This phenomenon, in average, appeared since 13 months after birth, About 50% of the whole began to show this phenomenon between 9 and 14 month after birth. 4. Half of the infants didn't show a change of attachment strength, but as for the other half, the attachment strength increased after one year of age, and decreased after three years of age, as the social period commenced. 5. Infants needed attachment objects especially when they were driven by sleep, sense of emptiness, and monotonous or boring feeling. 6. There were little difference between Object Attachment behavior and motherinfant attachment behavior except "babbling", "using her as a base for exploration". Those behaviors did not appear in Object Attachment. 7. mothers said that their children's attachment objects played the role of substitute mother, pacificater, warmer, friend , etc. And they attributed this phenomenon's appearance to lack their physical contact with, ocnstant and warm care toward, their children or bottle feeding.

As the traditional style is treated as one of the important themes in fashion recently, how to apply the formative character in Korean and Japanese traditional dress to modern fashion is searched through actual analysis of photograph material, Both design formative elements were confirmed by clothing and fashion department majors through visual data so that 20 pieces of them were selected as final analysis object. Korean traditional dress form in modern fashion emphasizes curvaceousness as plane division. On the other hand, that of Japanese shows straight line, layered, belt, big look through up & down connection style. Color in Korean traditional dress prefers white and original color and modern fashion displays the natural beauty through harmony of similar colors ; that of Japanese based on natural color such as persimmon color cherishes natural beauty and implicit moderation showing harmony of various original color with brilliance and neutral color. While texture in Korean traditional dress was fine and exquisite, that of Japanese preferred coarse and tactile ones. In motif, Korea was natural and geometric but Japanese variously used complex and geometric ones. Likewise, the result suggests that the formative character in Korean and Japanese modern fashion affects the modern dress format as new aesthetic sense and takes on more complicated and subtle aspect in basic form, not just use so far.

Argon laser used in this case report, is special in having two wavelength of 488, 514nm blue-green visible light spectrum. Blue light is used for composite resin polymerization and caries detection. Green light is used for soft tissue surgery and coagulation. Maximum absorption of this laser light occurs in red pigmentation such as hemoglobin. The argon laser may be well-suited for selective destruction of blood clots and hemangioma with minimal damage to adjacent tissues. Argon laser light penetrates tissue to the 1 mm depth, so its thermal intensity is lower than $CO_2$ laser light. Also, due to its short wavelength it can be focused in a small spot and even single gene can be excised by this laser and microscopy. After applicating argon laser to 4 patient for surgical procedure and to 1 patient for curing the composite resin, following results were obtained. 1. Improved visibility were gained due to hemostasis and no specific technique were needed according to easy recontouring of the tissue. 2. Ability to use by contact mode, tactile sense was superior but tissue dragability and accumulation of tissue on the tip needed sweeping motion. 3. Additive local anesthetic procedure was needed. 4. No suture and less curing time reduced chair time, this made argon laser available in pediatric dentistry.

In this research, we investigated the effect of three visual feedback conditions (direct viewing, one-monitor viewing, and tow-monitors viewing) on the task performance of human operator in teloperation task. The three different level of task difficulties under each concitions were performed by thirty-six subjects. The result of the experiments was analysed by the task difficulties, and the measurements of performance are the task completion time and the frequency of task errors. In a teleoperator, the participation of a human operator is always required, and the man-machine interface and the operator's abilities is an important issue. Recently, the different types of sensory feedback conditions(force, vision, sound, tactile, etc) for teleoperation is a very active research area in ergonomics. Among them, visual feedback conditon is an important sense that can provide the information of task environment. Therefore, the sufficient understandings and investigation for human ability under various visual feedback conditions is required to establish the efficient man-machine interface of teleoperation. The result showed that the visual feecback conditions and the level of task difficulties have a significant effect on the task performance. For three level of task difficulties, the task completion time was the shortest under the condition of direct viewing. The number of task errors under the conditions of direct viewing and two-monitors viewing were reduced by more than half compare to that of one-monitor viewing.

Harmony between men and their surroundings has been one of the most profound motives in space and object design for a long time. It is often expressed in design as the concept of 'organic'. Nowdays the term of organic is expanding its meaning in the contemporary sense of organicism. Nature, human 'beings, and digital technology are the key issues in future design paradigms. Karim Rashid is one of the most futuristic and vendible designer and his works show these issues. His designs flow organically and he uses materials that allow his forms to flow like the body, echoing life forms. it's very sensual, very tactile. In his work, a new concept of organic design is expressed in the organic unity of experience. He tries to contribute objects to our physical landscape that inspires, engages, and encourage positive experiences. Also, Technology is at constant play in his design process. With the latest three dimensional design software it is much easier to design and model sophisticated and complex shape and forms. Digital technology affects not only his design processes but also cultural views. New technologies and social shifts are changing our understanding of interior space.

A Study on the Plasticity of the Gather Represented in Haute Couture The Gather is the plastic technique to represent a sense of voluminosity by pleating the plane of costume and manifests the emotional effects , such as both functional aspects and the construction of form, optical illusion effect, textural feelings from materials, tactile transformations, etc. So it is used as the tool to represent the plastistic beauty of costume. The plasticity of the ancient gather was the drape arising according to the curve of the body, but the type of gather recently found on the haute couture does not only retain the activity and functionalism on which the technical element and the ornamental aspect are mixed with other techiques.

In modem days when architectural materials have grave impacts on overall design expression, materials for architecture, especially finishing materials have become the most essential elements for the design expression, as architectural space and form have been. When it comes to the architectural materials, they can be conceived by visual and tactile sensory system and perceptional system which based on memory and experience. This study confirms how materials bring into effect on architecture in the sense of its design. The main subject of this analysis is expression method of architectural finishing materials. Also, this study finds out the relationship between finishing materials and the images of materials by analyzing the effect factor of architectural material expression with the perspectives of materials, formal and environments and by examining roles of the architectural materials in design. The material factor, in the expression of materiality, is how to make tectonic space and to vary the surface of building as finishing material design. The formal factor is related to set up the new direction in the architectural form and to create the dynamic and informal space. And the social and cultural environment as the effect factor gives new situation and context to architectural material expression. This principle enables us to use architectural materials as one of the important elements which express the whole characteristics of the area.
