충돌/유출냉각은 연소실 벽면 등과 같이 열부하가 많이 걸리는 영역에서 고온의 연소가스로부터 표면을 보호하는 막냉각과 더불어 내부에 다공성 판을 설치하여 충돌제트에 의해 내부표면을 냉각시켜 가스터빈엔진의 고온요소의 냉각성능을 극대화시키는 방법 중의 하나이다. 이와 같은 냉각방법을 적용하면 벽면을 충돌제트에 의한 냉각과 함께 냉각유채를 막냉각에 활용함으로써 냉각효율을 극대화할 수 있다. 본 연구에서는 국소적인 값들을 획득하기 용이한 물질전달실험방법의 하나인 나프탈렌 승화법을 이용하여 수직으로 분사되는 충돌제트에 의한 유출판 내면에서의 열/물질전달특성을 분사판(injection plate)과 유출판(effusion plate) 사이의 높이, 분사제트의 속도, 분사홀간의 배열을 변화시켜가며 유출판만이 있는 경우와 비교, 분석하였다. 분사홀과 유출홀의 관 사이의 간격은 0.33d에서 10d까지 변화시켜가며 그 효과를 관찰하였으며, 홀배열 효과를 보기 위하여 2가지 홀배열(staggered array, shifted array)에 대하여 실험하였다. 또한 분사제트의 속도효과를 고찰하기 위하여 분사제트의 Rc$_{d}$=5,000-12,000까지 변화시켜가며 실험을 수행하였다.

The objective of this study was to understand the origin and characteristics of stone tower's style through the study of the 'Village Shrine at Seoji-ri, Andong'. The three kinds of stone towers were located forming a line of 9m on the hill of a red pine forest along the stream in the village. Toward the direction looking at the village, the three-story stone located on left, the two-story stone located in the middle, and the common style stone tower located on right. The bottom part of the three-story stone was 2.5m in length, 1.8m in width, 1.3m in height. The bottom part of the two-story stone was 1.3m in length, 1.5m in width, 0.9m in height. The common style stone heap tower was 3.0m in diameter, 1.8m in height with a cone shape. The small hat-shaped stone was presumed to be the top part of a three-story stone. According to the three factors(heaven, earth, human) of the idea of the universe in Korea, most ancient remains have components of odd numbers. Then it had been substituted with smaller three-story stone(at present, two-story stone). And then altered to a common stone tower later, such as the 'Village Shrine at Seoji-ri, Andong' that shows the combination of the Bronze Age's megalithic and a folk religion. The 'Village Shrine at Seoji-ri, Andong' is a valuable relic that shows the stone towers, and is derived from the Bronze Age. The 'Village Shrine at Seoji-ri, Andong' shows that the 'Village Shrine at Seoji-ri, Andong' was embodied the three-factor(heaven, earth, human) idea of the universe in three-story stone of megalithic culture' remains.

General development basis of letter system is recognized by formative value in terms of its function and structure. principle of clustered writing is the most significant feature of Hangeul typography as considered that it is based on function and formativeness. Thus, not only by changes with its form but also by its characteristic syllable combination, space structure is made as consonants and vowels are combined in single letter, then the combination develop into word, sentence, paragraph to make second, third space structure character. This character has significant impact on readability that is core function of typography. With this property, space structure character is regarded as very important component of Hangeul typography. First, space structure character of Hangeul typography is reviewed by relating it to visual perception of gestalt psychology and compared square-framed letter and framed latter By applying square-framed letter and framed latter in same sentence, legibility and readability were studied. Researcher has found that space structure character of Hangeul typography has significant impact on its function, and in terms of future design, it is very critical not only for design but also for communication environment as space structure formativeness of Hangeul typography interact with communication that is basic concept.

Recently, the interest and demand on free formed structure providing aesthetic value as well as functionality has been increasing. Formwork has numerous advantages such as high strength, convenience, accuracy and good quality of surface roughness. Nevertheless, it increases construction cost and period to build complex shapes. For these purpose, deposition construction systems such as Contour Crafting and Concrete Printing have been developed with active collaboration between university and industry by applying the rapid prototyping technology to the construction industry in USA and England. Since there has been no related research in Korea, the possibility of spin-off technology and its fusion cannot be expected. In this paper, design elements including mechanical system and control system related to automatic deposition construction system prototype for constructing a free curved structure without mold are described. As for an appropriate material for the system, fiber reinforced mortar was selected by experiments on compressive strength, fluidity, viscosity and setting time. By performing transfer and extrusion experiments, the possibility of the development of deposition construction system was demonstrated. Based on this research results, it is required to keep the automatic deposition construction system improve and extend it into the new application area in construction industry.

Kenzo Tange was interested in how to express tradition in the process of creation of modern architecture and tried to express the traditionaluty of Japanese architecture in his own way. In particular, Tange expressed Japanese tradition in terms of building materials and components from the point of view of his own 'New Tradition'. Tange created the 'Japanese style of architecture' based on traditional architecture to match the discourse of international architecture and distinguish it from the Western one, by harmonizing the plasticity of Japanese traditional architecture with the Western technology in building materials and components. Therefore, this study aimed to analyze the signs and traces of traditions in the building materials and components in his architecture. Through this study, I would like to have implications for our architecture, which had a very different process and result from Japan in digesting and combining it with traditional architecture although Western civilization was accepted at about the same time.

In 1990s with the increasing of consumers' standard of life and change of life style, there has been an increase of import from overseas license brands and a new participation of big enterprises, as well as small and medium enterprises in local fashion market. As a leading fashion company with a long tradition and technique, the INDIAN brand of Sejung Inc. needs to establish a new image to preoccupy relative superiorty in the competition with other brands and satisfy future consumers in the present situation of 1990s. Therefore, for developing of its image, we made an investigation of three-dimentional marketing about business environment, and after setting up the B.I concept, we initiated to express a visual image. Through a made-up question after the completion of those works, we decided our logo mark and completed the entire design system, including the basic and applied elements of main design items of INDIAN B.I Finally, to maximize the effect of the brand identity, it is necessary for us to keep the principles in making the shape of design, to take care of them thoroughly, to make all the members' thinking and behavior unite concerned with the brand, and to execute continuous educational programs for practice of B.I. conciousness with the public relations when B.I. will be appeared on the market.

The CGI(Computer-generated Image) techniques provide designers with an effective means of creating design artifacts in an automatic way. It has been pointed that two important activities while applying the CGI techniques are both image generation and managemental issues for the generated images. By applying automatic generation techniques for creation of images, designers can acquire benefits in that they can produce free style results in a simple way. Along with such benefits, it is also important for designer to identify and to establish well defined mechanisms for storing vast quantity of auto-generated CGIs. However, it is problematic to assign key-words and to classify abstract images mainly because they lack an analogy of the real world entities. This paper presents classification scheme for the abstract CGIs by applying classification and description criteria from the viewpoint of both design elements and emotional elements. Effective classification and specification can help designers build and retrieve desired images in an easy way, and make management process more simple and effective.

The color is silent language. As the cinematography modeling of art color of film of one of element even is that a synthetical special language systematic.The color of film is very symbolic. The symbolism of color is to express in metaphor some sort of rationality and concept with some color. Now a lot of directors are obsessed with the use of color to express the symbolic meaning. Gradually, the color goes beyond the form of natural material and ascends in appearance to a kind of significant and meaningful modeling element. Thus the color's symbolic meaning has become an essential element in the color and function of the film. The paper analyzes the applications of color in films by use of the well-known director Zhang Yimou's film such as "Hero" and Michelangelo Antonioni's film "Red desert"; and then makes"Hero" with the "Red desert" in order to explain different applications and expressing practices of colors in the film and reflect the significance of color as a unique expressing language in the film.
