Contemporary architecture is developing aspects of variety design in form and material. The various architectural trends even change classical materiality. This concept has the background of current idea - digital, information, imagination with paradigm. So this study aims to show the present status of the expressions in the contemporary architecture in Korea under its dematerialized situation. And like this, we know for study about the relation between dematerialization and current architecture, still more Korean present condition. In chapter one, the background, purpose and method of study are explained. In chapter two, this study inquires the general concept of dematerial. In the process of searching for the forming basic background this study understands the characteristic. In chapter three, this study inquires the aspect of dematerialized expression in modern architect. In chapter four, with characteristics drawn in chapter three, this study show the present status of the expressions in the contemporary architecture in Korea under its dematerialized situation. In chapter five, a synthetic conclusion is presented.

Two-color 적외선 탐색기는 표적의 대응 능력과 배경 잡음이 존재하는 상황에서 효율적인 표적 추적을 위해 두 개의 검출 대역을 사용한다. 본 논문은 Two-color 탐색기의 검출 대역 선정에 관한 연구이다. 검출 대역을 선정하기 위해, 표적, 섬광탄, 및 배경 잡음의 적외선 방사 특성을 분석하고, 수신 전력과 깊이 관련된 대기 투가 특성, 검출 가능 거리, 배경 잡음의 영향, 신호 대 잡음비 등의 특성을 분석한다. 분석 결과, two-color 적외선 탐색기의 적절한 대역은 표적 검출을 위한 3$\mu\textrm{m}$~5$\mu\textrm{m}$ 대역과 반대응 능력을 위한 $1.5\mu\textrm{m}$~1.7$\mu\textrm{m}$ 대역으로 나타났다. 본 논문의 연구 결과는 two-color 탐색기의 추후 연구에 중요한 역할을 할 것이다.

The purpose of this study was to investigate Renaissance wall-covering fabrics through Flemish paintings, that provides the details of the origin and development of background of modern wallcovering. The methods of the study are as follows. First, the background of textile development of Flanders in the 14^th to 16^th centuries were examined through a prior study. Second, the shape and use of wallcoverings in paintings painted during that time were analyzed and the process of changing to modern forms was studied. The residential environment with many stone buildings in relatively humid and cold weather created a need for decorative fabrics. Back then, the wool and flax fabric were not allowed to be worn on the body, so the materials were used for the development of interior fabrics. The characteristics of wall covering in Flemish paint can be summarized with movable, allegory, and decoration. Movable stems from the arrival of the emerging aristocrats of Flanders, who had enormous commercial trade and carried decorative fabrics; the mobility has become an allegory in reality as the royal and aristocratic use of wall-decorated fabrics is the symbol of authority. In addition, unlike Italy, where silk was procured from the East, fabrics manufactured using flax and wool were not suitable for clothing in terms of religion and practicality and were used to decorate walls.

유한한 폭을 갖는 배경에서 기본 어두운 공간솔리톤의 진행특성을 실험적으로 연구하여 전산시늉한 결과와 비교하였다. 실험적으로 빔의 세기가 증가함에 따라 어두운 솔리톤의 폭이 감소하고 배경의 폭은 증가함을 확인하였고 무한한 폭의 배경을 가정한 솔리톤 상수로부터 구한 굴절율의 변화량은 Z-스캔 방법으로 구한 굴절율의 변화량보다 작았다. 유한한 폭을 갖는 배경에 놓인 기본 어두운 솔리톤의 진행을 전산시늉하여 진행거리에 따른 배경의 첨두세기, 어두운 솔리톤의 폭 그리고 솔리톤 상수의 변화를 연구하였다. 유한한 크기의 배경에서 솔리톤상수의 변화를 고려하여 구한 굴절율의 변화량은 Z-스캔 방법으로 구한 굴절율의 변화량과 일치하였다.

In order to preserve the traditional garden landscape and maintain the harmony between traditional and modern gardens of Inner Mongolia, this study theoretically examined the creation and background elements of Inner Mongolia, and reviewed the nature of the people and the traditional design elements. The results of this study show that: 1) the background factor of traditional garden landscapes was nomadic life in plains, which was a lifestyle of adapting to Mother Nature and promoting mutual existence and survival; 2) Shamanism impacted the views of nature among the ancient Inner Mongolian people; 3) traditional garden landscapes could be categorized into landscapes centered around Mother Nature during the Huns era and those centered around the symbolic landscape during the Genghis Khan era; 4) aesthetic elements of traditional garden landscapes included traditional colors of red, yellow, sky-blue, milky-white, and traditional patterns of external knot, cloud, bull horn, and plain grass. These findings may provide basic data for the creation background and characteristics of traditional garden landscape of Inner Mongolia in the application of the green space design of Inner Mongolia.

The purpose of this study was to compare the differences between traditional and nontraditional college women in regard to personality and family background characteristics. Subjects were 180 college women majoring in Education, Nursing, Medicine, and Law. ANOVA and discriminant analysis were conducted to analyze the data. The results showed that nontraditional women scored significantly higher in acacemic achievement, SES, and parental support and influence than traditional women. SES, psychological masculinity, and parental support and influence were the most powerful predictors of nontraditional career orientation. Suggestions were made regarding precautions and need of cross-cultral study.

This paper proposes a method that automatically extracts characteristics of cracks such as length, thickness and direction, etc., from a concrete surface image with image processing techniques. This paper, first, uses the closing morphologic operation to adjust the effect of light extending over the whole concrete surface image. After applying the high-pass filtering operation to sharpen boundaries of cracks, we classify intensity values of the image into 8 groups and remove intensity values belong to the highest frequency group among them for the removal of background. Then, we binarize the preprocessed image. The auxiliary lines used to measure cracks of concrete surface are removed from the binarized image with position information extracted by the histogram operation. Then, cracks broken by the removal of background are extended to reconstruct an original crack with the $5{\times}5$ masking operation. We remove unnecessary information by applying three types of noise removal operations successively and extracts areas of cracks from the binarized image. At last, the opening morphologic operation is applied to compensate extracted cracks and characteristics of cracks are measured on the compensated ones. Experiments using real images of concrete surface showed that the proposed method extracts cracks well and precisely measures characteristics of cracks.

Most of precedent studies related to hip hop culture and fashion, which have been conducted till now were progressed under only theoretical background of hiphop, not the changed status of hiphop currently. Practical studies explaining the status of hip hop in popular culture, especially, the area of popular fashion are insufficient. Therefore, this study was conducted by focusing on cultural characteristics and musical characteristics by the stream of period, for which concept hip hop is accepted to people currently and which effect it makes on the area of fashion. Especially, the study was progressed by dividing periodical background into before and after the 2000s because there was the most noticeable change for the genre of hip hop in that period. Because of the appearance of 'Alternative hip hop' which is a sub-genre of hip hop music, hip hop music was changed to be more popular. Also, hip hop fashion also showed big changes. Hip hop fashion before 2000s had showed poor conditions, resistance, complex and alienation of them by their fashion. On the other hand, hip hop fashion after 2000s also showed popular characteristics because of high-level environment and social status. This study intended to understand and grasp hip hop as a kind of cultural situation coexisted by many-sided characteristics as well as redefine the changed concept and contents of new hip hop currently.
