본 연구는 중학생의 자아개념, 즉 일반자아, 학문자아, 중요타인자아, 정의자아개념에 따라 외모관리행동인 의복스타일추구, 화장 및 피부관리, 헤어관리, 성형 및 체형보정, 체중관리행동에 어떠한 차이가 나타나는지 살펴보고자 하였다. 특히 가정이나 학교 등의 생활 지도 현장에서 중학생의 외모관리행동은 세대 간의 의견차가 보이는 영역이므로, 이 연구를 통해 중학생의 외모관리행동을 이해할 수 있는 기초 자료를 제공하고자 하였으며, 가정교과교육을 통한 자아개념의 증진 방안을 모색하는데 기초자료를 제공하기 위해 본 연구를 시행하였다. 본 연구를 통해 얻어진 결과를 요약하면 다음과 같았다. 본 연구의 조사대상자인 중학생들은 평균적으로 자아개념이 낮아 자신을 부정적으로 인식하고 있었으며 외모관리 행동 또한 낮은 것으로 나타났다. 자신을 긍정적으로 볼 수 있는 노력과 함께 외모관리행동을 통한 자아개념의 긍정적 증진이 필요하다고 하겠다. 긍정적 자아개념을 가지고 있는 중학생들은 피부를 청결하게 유지하는 것이나 헤어를 아름답게 손질하고 가꾸는 것 등으로 자신을 나타내려하며, 옷, 신발, 가방을 잘 갖추어 입고 깨끗하게 관리함으로써 스스로의 자존감이나 개성을 표현하려고 하였다. 또한 자신을 인식할 때 공부와 학업에 대해 긍정적 태도를 보이며, 중요시되는 타인과의 관계를 원만하게 지각하고, 자신의 신체나 정서에 대해 긍정적인 태도를 보이는 중학생들은 의복에 대해 높은 관심을 가지고 자신이 추구하는 이미지를 나타내려는 행동이 높은 반면, 성형이나 체형 등 자신의 신체를 인위적으로 변경시키려는 행동은 적게 하는 것으로 나타났다. 적절한 외모관리행동은 자신을 긍정적으로 보는데 도움을 줄 수 있을 것이다.

Microbial cellulose has many potential applications due to its excellent physical properties. The production of cellulose from Acetobacter xylinum in submerged culture is, however, beset with numerous problems. The most difficult one has been the appearance of negative mutants under shaking culture conditions, which is deficient of cellulose producing ability. Thus genetic instability of Acetobacter xylinum under shaking culture condition made developing a stable mutant major research interest in recent years. To find a proper type of bioreactor for the production of microbial cellulose, several production systems were developed. Using a reactor system with planar type impeller with bottoms sparging system, it was possible to produce 5 g/L microbial cellulose without generating cellulose minus mutants, which is comparable to that of static culture system.

The importance and the interest of wind load have emphasized since the damage of the Jeju World cup Stadium and Main Stadium of Busan Asiad in 2002, and the appearance of high-rise buildings. In general, a evaluation for the wind load acting on structures have been carried out mainly through the wind tunnel test, but this technique has the huge shortcomings that consume too much cost and experimental time. However, with the rapid advances on computers, it is possible to analyze the wind pressure distribution acting on structures by numerical scheme. In this paper, to predict the wind pressure distribution acting on shell structures having the various shape by numerical simulation, governing equations of fluid flow and turbulent model is formulated. Also, evaluates the wind pressure coefficient in accordance with the structural shape for shell structures like as a membrane structures and dome structures.

Lighting is the single most important part of the design of a retail store. Good lighting can enhance a product's appearance, accentuate a special display, balance the visual elements of a store, and create the proper mood. In shops the lighting is required to draw the customer's attention to the goods help him to appraise them, and provide an atmosphere conducive to sales. The method will vary according to the types of good displayed, the form of trading, the design of the shop, and the class of customers expected. For the all reason, this study is focused on how the lighting design effects the customer's interest to the goods and intended to prescribe the possibilities of effective lighting design.

A burr has been defined as undesirable projection of material formed as the result of plastic flow from a cutting or shearing operation. It is unavoidable in all kinds of machining operation. As a result, burr makes troubles on manufacturing process due to deburring cost, quality of products and productivity. In face milling operation, burrs are formed along five edges on the workpiece. In this study, the primary interest is about exit burr The influence of the cutting parameters on the formation of exit burrs in face milling will be described experimentally. Using the results of experimental study, burr types are classified according to appearance and formation mechanism in exit burr. The burr formation mechanism in each type of burr is suggested. Data bases are developed to predict burr formation result.

The purpose of the research was influential in the fashionable dacolleta of women's costume in the mid-l5th century. The results were as follow: A variation of social environment and an aesthetic sense brought on desires to express human nature. Especially, the importance for costume of the appearance of a new spirit, confirmed and developed on the contemporary. The first symptoms of humanism were leaning towards secular art, an ideal of man at once more independent and avid for action, and an interesting applied to the individual and particularity. In addition, love affairs between the ladies and knights led to increasing interest in the beauty of weakness and tenderness in the women's body Sorel Agnas who was a lover of Charles VII, France king, had a great influence on the fashion of decollette in women's costume. It was just a dacolletta to express an ideal of beauty to neckline in women's dress in contemporary.

Recently with increasing interest in the natural science history education, a lot of natural science museums have been developed in various locations. This project is located in one of the biggest Paleozoic site, Taebak Kangwon-do. This kind museum has had important rolls in terms of education for student, destination for traveling and reservation of important holdover of the old ages. To do those kind of parts, this project has been designed with concepts and themes like; i. being organized with story telling structure with theme "secret of life and earth from Taebak" ii. combining experiences between outdoor experimental search for the real fossils and indoor educational interactions with real size model and moving films. iii. designing with strong identities of Paleozoic era. For the design identities the outer appearance was designed with motive of trilbites in an abstract way and inside was finished with exposed concrete and various size of moving films projected to walls and floor to emphasize real scale experience of the old ages.

The appearance of on-demand business model of multimedia contents is one of the biggest changes in the broadband Internet which aims at the high-speed Internet users. Currently the interest in the webcasting service, a new converged service of the broadcasting and the telecommunications, has been increased. However the quality of service is not guaranteed due to the bottleneck problem in a middle-mile as the fundamental limit of the Internet, and has not been improved greatly due to the small-scaled operators of the webcasting services. This study suggests a new business model of the multi-channel satellite webcasting service based on the satellite multicasting and content delivery network, which guarantees the quality of service and channelizes the contents by the type or by the special purpose.

흑점수와 오로라의 관측 자료를 과거로 연장해 보면 dynamo 이론과 태양의 활동 그리고 기후간에 상당한 관계가 있음을 알 수 있다. 특히 흑점이 거의 나타나지 않았던 Maunder 극소기가 이상 혹한기였던 유럽의 소빙하기와 일치하고, 흑점의 출현과 오로라 발생 사이에 밀접한 관계가 있다는 사실이 알려졌다. 이에 따라 Maunder 극소기 시기의 흑점과 오로라의 관측 자료들을 간접적 solar proxy 자료들과 함께 조사하고, 이 시기에 나타난 태양 활동의 모습과 특징을 기후변화의 관계와 함께 알아보았다.

Diagnosis of maxillofacial lesions is very difficult. Recent developments in computed tomography enable the production of three dimnesional images of complex anatomical structures from a series of conventional computed tomographic sections. Methods of three-dimensional analysis of computed tomographic images have recently been described. Mostly, reports have concentrated on applications relative to congenital deformities. In this report, one method of three dimensional reformatting is reviwes. Images formed by this method have solid surface appearance and can be color enhanced and manipulated to isolate anatomic structures of interest. The program allows tissue densitis, volumes, and distances. This report emphasizes maxillofacial applications other than those previously reported in the surgical and radiological literature.
