Visual media transmits image and information reproduced in large quantities, such as a photography, film, television, video, advertisement, or computer image. Correspondence to the students' reception and recognition of culture in the future. arrangements for the field of studies of visual culture. 'Visual Culture' implies cultural phenomena of visual images via visual media, which includes not only the categories of traditional arts like a painting, sculpture, print, or design, but the performance arts including a fashion show or parade of carnival, and the mass and electronic media like a photography, film, television, video, advertisement, cartoon, animation, or computer image. In the world of visual media, Image' functions as an essential medium of communication. Therefore, people call the culture of today fra of Image Culture', which has been converted from an alphabet convergence era to an image convergence one. Image, via visual media, has become a dominant means for communication in large part of human life, so we can designate an Image' as a typical aspect of visual culture today. Image, as an essential medium of communication, plays an important role in contemporary society. The one way is the conversion of analogue image like an actual picture, photograph, or film into digital one through the digitalization of digital camera or scanner as 'an analogue/digital commutator'. The other is a way of process with a computer drawing, or modeling of objects. It is appropriate to the production of pictorial and surreal images. Digital images, produced by the other, can be divided into the form of Pixel' and form of Vector'. Vector is a line linking the point of departure to the point of end, which organizes informations. Computer stores each line's standard location and correlative locations to one another Digital image shows for more 'Perfectness' than any other visual media. Digital image has been evolving in the diverse aspects, such as a production of geometrical or organic image compositing, interactive art, multimedia art, or web art, which has been applied a computer as an extended trot of painting. Someone often interprets digitalized copy with endless reproduction of original even as an extension of a print. Visual af is no longer a simple activity of representation by a painter or sculptor, but now is intimately associated with a matter of application of media. There is some problem in images via visual media. First, the image via media doesn't reflect a reality as it is, but reflects an artificial manipulated world, that is, a virtual reality. Second, the introduction of digital effect and the development of image processing technology have enhanced a spectacle of destructive and violent scenes. Third, a child intends to recognize the interactive images of computer game and virtual reality as a reality, or truth. Education needs not only to point out an ill effect of mass media and prevent the younger generation from being damaged by it, but also to offer a knowledge and know-how to cope actively with social, cultural circumstances. Visual media education is one of these essential methods for the contemporary and future human being in the overflowing of image informations. The fosterage of 'Visual Literacy' can be considered as a very purpose of visual media education. This is a way to lead an individual to the discerning, active consumer and producer of visual media in life as far as possible. The elements of 'Visual Literacy' can be divided into a faculty of recognition related to the visual media, a faculty of critical reception, a faculty of appropriate application, a faculty of active work and a faculty of creative modeling, which are promoted at the same time by the education of 'visual literacy'. In conclusion, the education of 'Visual Literacy' guides students to comprehend and discriminate the visual image media carefully, or receive them critically, apply them properly, or produce them creatively and voluntarily. Moreover, it leads to an artistic activity by means of new media. This education can be approached and enhanced by the connection and integration with real life. Visual arts and education of them play an important role in the digital era depended on visual communications via image information. Visual me야a of day functions as an essential element both in daily life and in arts. Students can soundly understand visual phenomena of today by means of visual media, and apply it as an expression tool of life culture as well. A new recognition and valuation visual image and media education is required to cultivate the capability of active, upright dealing with the changes of history of civilization. 1) Visual media education helps to cultivate a sensibility for images, which reacts to and deals with the circumstances. 2) It helps students to comprehend the contemporary arts and culture via new media. 3) It supplies a chance of students' experiencing a visual modeling by means of new media. 4) There are educational opportunities of images with temporality and spaciality, and therefore a discerning person becomes to increase. 5) The modeling activity via new media leads students to be continuously interested in the school and production of plastic arts. 6) It raises the ability of visual communications dealing with image information society. 7) An education of digital image is significant in respect of cultivation of man of talent for the future society of image information as well. To correspond to the changing and developing social, cultural circumstances, and the form and recognition of students' reception of them, visual arts education must arrange the field of studying on a new visual culture. Besides, a program needs to be developed, which is in more systematic and active level in relation to visual media education. Educational contents should be extended to the media for visual images, that is, photography, film, television, video, computer graphic, animation, music video, computer game and multimedia. Every media must be separately approached, because they maintain the modes and peculiarities of their own according to the conveyance form of message. The concrete and systematic method of teaching and the quality of education must be researched and developed, centering around the development of a course of study. Teacher's foundational capability of teaching should be cultivated for the visual media education. In this case, it must be paid attention to the fact that a technological level of media is considered as a secondary. Because school education doesn't intend to train expert and skillful producers, but intends to lay stress on the essential aesthetic one with visual media under the social and cultural context, in respect of a consumer including a man of culture.

Recently, one of the critical issues in the etching processes of the nanoscale devices is to achieve ultra-high aspect ratio contact (UHARC) profile without anomalous behaviors such as sidewall bowing, and twisting profile. To achieve this goal, the fluorocarbon plasmas with major advantage of the sidewall passivation have been used commonly with numerous additives to obtain the ideal etch profiles. However, they still suffer from formidable challenges such as tight limits of sidewall bowing and controlling the randomly distorted features in nanoscale etching profile. Furthermore, the absence of the available plasma simulation tools has made it difficult to develop revolutionary technologies to overcome these process limitations, including novel plasma chemistries, and plasma sources. As an effort to address these issues, we performed a fluorocarbon surface kinetic modeling based on the experimental plasma diagnostic data for silicon dioxide etching process under inductively coupled C4F6/Ar/O2 plasmas. For this work, the SiO2 etch rates were investigated with bulk plasma diagnostics tools such as Langmuir probe, cutoff probe and Quadruple Mass Spectrometer (QMS). The surface chemistries of the etched samples were measured by X-ray Photoelectron Spectrometer. To measure plasma parameters, the self-cleaned RF Langmuir probe was used for polymer deposition environment on the probe tip and double-checked by the cutoff probe which was known to be a precise plasma diagnostic tool for the electron density measurement. In addition, neutral and ion fluxes from bulk plasma were monitored with appearance methods using QMS signal. Based on these experimental data, we proposed a phenomenological, and realistic two-layer surface reaction model of SiO2 etch process under the overlying polymer passivation layer, considering material balance of deposition and etching through steady-state fluorocarbon layer. The predicted surface reaction modeling results showed good agreement with the experimental data. With the above studies of plasma surface reaction, we have developed a 3D topography simulator using the multi-layer level set algorithm and new memory saving technique, which is suitable in 3D UHARC etch simulation. Ballistic transports of neutral and ion species inside feature profile was considered by deterministic and Monte Carlo methods, respectively. In case of ultra-high aspect ratio contact hole etching, it is already well-known that the huge computational burden is required for realistic consideration of these ballistic transports. To address this issue, the related computational codes were efficiently parallelized for GPU (Graphic Processing Unit) computing, so that the total computation time could be improved more than few hundred times compared to the serial version. Finally, the 3D topography simulator was integrated with ballistic transport module and etch reaction model. Realistic etch-profile simulations with consideration of the sidewall polymer passivation layer were demonstrated.

인터넷 기술의 발전에 따라 분산 지리정보 시스템 환경이 웹 기반 서비스로 변화되고 있는 추세이다. 기존의 웹 지리정보 서비스의 지리정보는 다양한 지도 포맷을 지원하여 상호운용하지 못하도록 독립적으로 개발되어 왔다. 동일한 지리정보임에도 불구하고 이러한 정보는 서로 다른 목적에 따라 개별적인 지리정보 시스템에 의해 중복된다 이는 중복된 지리정보 객체를 식별하는 문제와 중복된 지리정보 객체들 중에 클라이언트에게 가장 적합한 복사본을 선정하기 위한 지능적인 전략이 요구되고 있다. 그리고 중복 객체를 관리하기 위해 OMG와 GLOBE 그리고 GRID 컴퓨팅에서 관련 프레임워크를 제안하고 있다. 그러나 지리정보 객체에 대한 연구는 미흡하다. 따라서, 본 논문에서 이름 또는 속성으로 중복된 서비스 객체들의 효율적인 관리와 중복 서비스 객체들 중 가장 적합한 객체를 선정하기 위한 위치 서비스 모델을 제시하였다. 위치 서비스 모델은 세 개의 주요 서비스로 구성되어 있다. 첫 번째로 바인딩 서비스는 사용자가 객체의 이름과 속성으로 정의하여 서비스 오퍼 단위로 저장하고 클라이언트가 서비스 오퍼를 검색 할 수 있다. 두 번째는 위치 서비스로 컨택 레코드를 갖는 위치 정보를 관리한다. 그리고 컨택 주소를 갖는 독립적인 시스템상의 LSF에 의해 성능 정보를 획득한다. 세 번째는 지능형 선정 서비스로 바인딩/위치 서비스로부터 기본/성능 정보를 획득하고, 러프집합 기반의 지능형 모델에 의한 규칙에 의해 보다 빠르게 접근하고 성능이 우수한 특징을 제공한다. 본 논문에서 제시한 위치 서비스 모델에 대한 검증을 위해 그래픽 사용자 인터페이스를 통해 위치 서비스의 처리 과정을 보였다.효과를 나타냈다.\alpha}-amylase$ 활성을 고려한 적정 종자수분 함량은 단옥수수는 15%, 초당옥수수는 12%이었다.미관련(食味關聯) 미질특성(米質特性)을 이용한 토요식미치 추정(推定) 중회귀식(重回歸式)에 채택(採擇)된 주요 특성은 단백질함량, 알칼리붕괴도 및 최저점도(最低粘度)였으며 결정계수(決定係數)로 보아 약 49%의 적중율(的中率)을 나타내었다. 생물학적 기능의 상관관계를 이해하는데 활용될 수 있을 것이다.V는 앞으로 바이러스와 기주의 다양한 상호관계를 이해하는데 있어서 중요한 병원학적 성질을 가지고 있는 것으로 생각되었다.>$300^{\circ}C$ 이하, 공정압력 1 Torr, 그리고 bias전압과 기체 혼합비를 변화시키면서 증착하였다. 증착시 in-situ OES 분석결과 플라즈마 내의 질소종의 함유량 변화에 따라 증착속도가 크게 변화됨을 알 수 있었고, 많은 질소기체를 인입하면 질소종이 많아지지만 증착률은 급격히 감소하였고 박막내 탄소의 함량이 커지면서 막질이 비정질로 바뀌고 미세경도 또한 감소함을 알 수 있었다. 이는 in-situ 플라즈마 진단분석이 전체 PEMOCVD 공정에 있어서 대단히 중요하고, Ti(C,N)과 Hf(C,N) 코팅막의 탄소함량과 미세경도는 플라즈마내의 CH과 CN radical종의 세기에 크게 의존함을 의미한다. 그리고 Hf(C,N) 박막의 경우도 Ti(C,N) 박막의 경우와 유사하게 최대 미세경도값$(2460\;Hk_{0.025})$이 -600 V bias 전압과 10% 질소기체 혼합비를 사용한 경우에 얻어졌고, 이는 박막이 주로(111) 방향으로 성장됨에 기인한 것으로
