In this paper some of the important trends in the spacecraft technology development have been discussed. Trends of higher satellite radiate power, which involves higher TWTA powers and antenna reconfiguration, and Ka-band (30/20 G $H_{z}$) utilization are discussed. Evolutionary trends in satellite communications in general have demonstrated immense potential for meeting the evolving nees and challenges regarding provision of global telecommunications during over past two decades. Their promise for the coming decades as we enter the 21st century may far surpass our imagination. The expansion of fixed satellite service market will depend upon more inelligent spacecraft and a network of more cost effective small earth stations. Radiation hardened microwave analog technologies and high speed digital technologies are getting ready to meet the challenge posed by future markets. At present commercial satellite communications are going through a trasition period.d.

This paper shows about the machine simulation embodiment when it happened NC equipment and between workpiece and interference collision at 5 axises processing of aircraft parts. And this research has been chosen because of the highest equipment interference occurrence rate at aircraft parts processing of 5 axises horizontal machine. It can verify simulation and machining process through correlation about their dynamic relations. interference, collision as embodied virtual manufacturing system of machining tool, workpiece, and holder etc. that is necessary element in shape of machine tool and function and processing in imagination ball. Also. it verified about interference and collision between NC equipment parts and workpiece, for applied machine simulation to NC Data of actuality aircraft parts of BULKHEAD and FRAME.

Carbon nanotubes, consisting of rolled graphene layer built from $sp^2$ units, have attracted the imagination of scientists as ideal macromolecules and their unusual physical and chemical properties make them useful in the fabrication of nanocomposites, nano-electronic devices and sensors etc. In this account, the current status and prospect of carbon nanotubes is described with a special emphasis on the safety issue of carbon nanotubes. Even though many challenges to be solved remain, extensive and intensive efforts in both academy and industry will clear out those problems soon and finally enable carbon nanotubes to play a key innovative material of 21st century in numerous industrial processes.

세계 각국은 자국의 문화재를 보존하기 위해 많은 노력을 기울이고 있다. 디지털 복원 기술을 이용하여 문화재를 영구히 보존하려는 시스템 개발 또한 그 중 하나이다. 그러나 문화재는 유형의 물체뿐만 아니라 그에 얽힌 전설과 정신 또한 중요함에도 기존의 시스템들은 형태적인 복원에 치중한 것이 대부분이었다. 본 논문에서는 예술적 상상으로 가상현실 시스템을 이용해 문화콘텐츠 개발을 위한 예술기획 기법을 설명한다. 제안된 기법은 문화원형을 선정하고, 문화적, 예술적 분석과정을 거쳐, 그 결과를 가상현실 시스템에 적용한다. 기획된 내용은 문화콘텐츠 체험 시스템에 적용되었다. 예술기획 기법은 형태적인 측면에서의 문화재뿐만 아니라 그 동안 부재되었던 정신적인 측면 또한, 과제 삼아 문화재 복원의 진정한 의미를 가상현실 시스템에 담도록 하였다.

The purpose of this study is to consider critically the conceptural meaning and the arch itectural planning-techniques of environment-friendly architecture in Korean contemporary architecture. The related conceptual meaning and design-techniques on environment-friendly architecture are proposed by considering items in relation with adapting to natural environment, human life, historical imagination. These items are adapting technical methods to architectural design in a narrow sense. We have to reconsider its wide application. Through this consideration, this study is proposed a right direction of environment-friendly architecture in the future.

Objective : This study was to investigate the effect of oriental medical treatment for Asperger's syndrome. Methods : This patient was lack of social communication, interaction, imagination and motor coordination. It was due to Asperger's syndrome. The patient was treated with Herbal medicine, acupuncture and play therapy. And we evaluated the case with The Australian scale for Asperger's syndrome. Results : Oriental medical treatment and play thrapy alleviated his symptoms of Asperger's syndrome and anxiety. Conclusions : We report the good result of oriental medical treatment on this case. The more study of oriental medical treatment for Asperger's syndrome is needed.

Microbeam PIXE, often called micro-PIXE, is one of powerful tools for analyzing a wide range of elements for various samples. Moreover, it has important applications of interest to the atmospheric science. In the present study, a qualitative elemental imagination for various atmospheric environmental species was attempted using micro-PIXE. Especially, in combination with a novel individual droplet collection method and the micro-PIXE analytical technique, the chemical specification of various individual atmospheric samples could be carried out. Here, we briefly introduce the results of an application of micro-PIXE to the study of atmospheric environment. The detailed spatial resolution of multiple elements for various samples like individual ambient particles, individual raindrops, individual fog droplets, and individual snow crystals could be successfully achieved by scanning 2.6 MeV $H^+$ micro beam ($1{\sim}2{\mu}m$) accelerated by 3 MeV single-end accelerator.

The purpose of this study is to clarify the expansion of functions of clothes by analyzing the characteristics of transformation, and to forecast future trends in fashion through systematization of the aforementioned analyses. Analysis of 20th century Modernism and Post-Modernism in a sociocultural sense confirms that transformation in clothes was formed by environmental, functional, deconstructive, and expressive factors. In this sense, the formative factors mentioned above conceptually include nomadic characteristics, usefulness, irregularity, and expressiveness. The nomadic characteristics found in clothes transformation signify the change of clothes into environmental nomadic everyday implements, used as tools for the body. Usefulness of clothes means that it is worn for variability, multipurpose multi-functionality, and combined multiple use. Irregularity means the clothes can change indefinitely, according to random manipulation on the wearer's part. Last of all, expressiveness conveys the designer's internal sensitivity and imagination onto an external object through the induction of various expressive factors.
