본 논문에서는 미술품의 물리적 특징을 디지털화 하는 방법과 디지털 정보를 사용한 미술품 복원 방법을 다룬다. 미술품으로부터 취득할 수 있는 물리적 특성은 색상정보, 기하정보, 반사특성 등이 있고 미술품의 종류에 따라서 필요한 물리적 특성을 획득하기 위해서 미술품을 크게 2D, 2.5D, 3D 로 분류할 수 있다. 2D 미술품은 평면에 그려진 미술품으로 높은 해상도와 정확한 색상 정보 취득을 주 목적으로 하고, 2.5D 미술품은 평면의 미술품에 깊이가 추가된 유화나 판화의 형태로 2D 미술품의 특징에서 깊이표현 정보와 반사특성 정보를 추가로 취득한다. 3D 미술품은 입체적인 미술품으로 3 차원의 기하정보를 중심으로 디지털화 한다. 이렇게 취득한 미술품의 물리적 정보는 2D 미술품은 프린터로, 2.5D, 3D 미술품은 3D 프린터로 출력하여 복원하거나 디스플레이를 통해 가상으로 재현할 수 있다. 본 논문에서 다루는 디지털화 기술과 복원 기술은 높은 정확도를 위해 연구되었기 때문에 다양한 미술품의 디지털화와 복원에 사용될 뿐 아니라 다양한 분야에서 사용될 것으로 기대된다.

The article starts with a review of system characteristic, information characteristic and personal characteristic on educational performance through educational satisfaction. This survey is intended for educatee's who take the course of KcLep. We found that all variables of system characteristic(easiness, flexibility and reliability) significantly effect the educational satisfaction. Information characteristic(timeliness, usefulness) significantly effect on educational satisfaction, but the correctness doesn't significantly effect on educational satisfaction. Personal characteristic(self-efficacy and achievement motivation) significantly effect on educational satisfaction, but the computing ability doesn't significantly effect on educational satisfaction. We found that the educational satisfaction significantly effect on the education performance.

Recently consumers to access various Word-Of-Mouth information on online. And eWOM (eWOM : electronic Word-Of-Mouth) information had an important effect on consumer attitude(purchase intention). The purpose of this study is to investigate what the general characteristics of eWOM and the effects of how these factors will affect credibility, eWOM acceptance and purchase intention. In this study, the model contains information characteristics variables(consensus, newness), community characteristics(tie strength, interaction) on eWOM characteristics. This study makes contributions as follows. First, information consensus had not effect on credibility. Second, information newness and community characteristics(tie strength, interaction) had a significant on credibility. Third, credibility is the important factor on eWOM acceptance. Lastly, eWOM acceptance had a considerable influence on purchase intentions.

인터넷에는 다른 하드웨어적 특성을 갖는 다양한 형태의 이동노드가 존재한다. 이러한 특성이 무선통신 과정에 반영되어 다양한 문제가 발생한다. 이동 노드로만 구성된 무선 ad-hoc 네트웍은 이와 같은 특성에 큰 영향을 받게 된다. 기존의 ad-hoc 네트웍 라우팅 프로토콜은 목적 노드에 도달하기 위한 경로의 발견과 관리에 연구가 집중되었으며, 최근 이동노드의 특성을 라우팅 과정에 반영하기 위한 연구가 시작되고 있다. 본 논들은 ad-hoc 라우팅 프로토콜에서 이동노드가 갖는 이질적 특성을 라우팅에 반영하고, 이를 AODV 라우팅 프로토콜에 적용하기 위한 메커니즘을 제안한다. 본 메커니즘은 이동노드의 특성을 이용한 Proactive 방식의 노드가 추가되어 일반 이동노드에게 다중 홉의 경로에 대한 패킷 전송을 대신하며 주변 이동 노드에게 다중 홉의 라우팅 정보를 제공한다. Reactive 방식의 노드는 Proactive 방식의 노드를 발전하고 이용하기 위해 기능을 확장하였다. 이를 통하여 안정적인 경로를 선택 할 수 있으며 ad-hoc 네트워크 망의 확장이 가능하다.

The technology development is the one of the motive leading power to change the world. At this point of time, the most countries in the world take notice of the gifted science education because they believe that the development of a high-grade manpower resources is the only way of the development of their own country. Before the gifted education, however, the study of the gifted characteristics should be achieved first. Analysis of the intellectual characteristic in the research of the gifted characteristic has been accomplished with many of standardized test tool, however, analysis of the non-intellectual characteristics has not been researched with real sources because of the measuring method and the vogue range. Accordingly, this research will analyzed characteristics of the gifted in computers to focus on the non-intellectual through the difference of normal child. The field of the gifted in computers, in particular, hardly has been researched because the beginning of this study has a short period of time. Therefore, this research focus on analysis of the non-intellectual characteristics of the gifted in computer so that we understand well gifted child in computers in education of that.

There is very little information on mobile terminal service systems such as CRUMPET because the all the users have different situations and characteristic, and so it is also difficult to find correlations. Because of the difficulty of customizing and recommending information based on preference stemming from the users' various situations and characteristics, they usually provide limited, conceptual information. This paper will recommend a system that recommends information tailored to the user's situation and characteristics, using the Spearman correlation coefficients. It finds correlations from users' information and sequences information that is suitable to the user's situation and characteristics into a list, thereby solving the problem of limited, conceptual information. Performance tests have revealed when compared to existing service systems, this system is more effective in terms of precision and recall, with a 92.3% precision rate, and a 73.8% recall rate.
