  • This paper proposes that can take at high speed the information of binocular disparity with moving translational and forward stereo camera to the extent that does not occur the problem of a correspondence point. It shows that in case of stereo vision with translational motion, can take the information of binocular disparity being devoid of error and putting high confidence in, and that in case of stereo vision with forward motion, can take the horizontal component which can not be detected in common stereo vision. Besides, the stereo vision can be done at high speed due to being bright and small a correspondence point comparing not to do, because a correspondence between right and left images is previously limited. But there are problem that a resonable information of binocular disparity can not be taken, if the vicinity of center of image is in accord with the region of occlusion in stereo vision with forward motion.

  • This study is about the French preposition de. This preposition is considered to have no meaning in the French language, and to have only the grammatical function in its use. This study begins with doubts about such views regarding this preposition. We organize and classify general descriptions of the uses of this preposition. The uses are classified as 'expressing starting point,' 'giving characteristics' and 'performing grammatical functions' and this data is analyzed in terms of the associated cognitive grammar. In the case of expressing the starting point, it is assumed that the trajector moves from the starting point, to the destination point, in the domain of space and in the domain of time. Therefore, it is noted in this case that the preposition de has a dynamic concept. On the other hand, it is significant to understand that the preposition of the 'giving characteristics' defines an outline of a particular class by giving the class's characteristics. The preposition de has a static concept in this case. For the preposition de which introduces the infinitive, all of these dynamic and static concepts are faded and extremely grammaticalized.

  • Equatorial Plasma Bubble(EPB)은 적도 지역에서 Rayleigh-Taylor Instability에 의해 발생하는 이온층 플라즈마의 불안정성 현상으로, 주변의 플라즈마 밀도에 비해 좁은 영역에서 플라즈마 밀도가 급격하게 떨어지는 현상을 말한다. 지역적으로 보면, 겨울철에는 대서양 지역에서 집중적으로 발생하고 여름철에서는 태평양 지역에서 많이 관측된다. 이러한 불안정 현상은 단파 통신 장애를 유발할 수 있기 때문에 많은 연구 대상이 되어왔지만, 아직까지 태양 활동이나 지자기 변화에 의한 상호 연관성이 규명되지 못 하고 있다. 이것은 Rayleigh-Taylor Instability를 발생시키는 여러 인자들이 매우 복잡하게 관련되어 있기 때문인데, 본 연구에서는 특정 지역에서 발생하는 EPB에 한정하여 태양 활동과의 상호 연관성에 대해 분석하고자 하였다. 또한 단순한 발생 빈도에 대한 통계적인 처리가 아닌, EPB하나 하나에 대한 특성을 분석함으로써 EPB의 발생과 관련한 보다 명확한 분석이 가능하게 되었다. 분석에 필요한 data는 KOMPSAT-1의 Langmuir Probe(LP)에 의해 2000년에서 2001년 사이에 얻은 이온층의 전자 밀도를 사용하였는데, KOMPSAT-1의 LP는 같은 기간 활동한 다른 위성에 비해 좋은 시간 분해능을 가지고 있기 때문에 EPB의 통계 처리에 적당한 것으로 생각되었다.

  • 효율적으로 일하는 방법을 제시하는 프로젝트 관리 프레임 중의 하나인 PMBOK는 9가지 프로젝트 관리 영역의 필요성을 제시하고 있다. PMBOK 프로세스 연관도를 살펴보면, 네트워크 토폴로지의 특징인 노드, 링크, 순위, 빈도수와 관련된 유사한 면이 있는 것을 발견할 수 있다. PMBOK의 표준 프로세스 연관도에 따라 연결되는 링크를 순차적으로 그린다고 가정했을 때, 실제 업무의 프로세스 링크는 네트워크이론의 Power-law를 따를 것이라고 예상되었다. 이러한 현상을 증명하기 위해 PMBOK 표준 프로세스 연관도를 모델로 하여, 인터넷 위상의 특징을 결정하는 속성 중 Power-law1, 2의 관련성을 분석하였다.

  • It is the responsibility of the government organization in the field of history and archives to control preproduction of records and their production sphere. Moreover, it should also manage all kinds of archives and presidential records as its function is to manage and share public information, and carry out compilations of historical records. With this, this study explains how having all these functions would make the ideal reorganization of the government. It should correspond to principle of Government's reorganization such as transparency, responsibility, communication. A plan for reformation needs two-track approach. I would like to propose the establishment of the 'Ministry of National Archives' or the 'National Memory Committee' at the organization that is in charge of national records and memory management. It means that the National memory isn't limited to public sphere. In terms of Total archives, the organizations should contain the whole community's memory. This organization should be formed independently.

  • The purpose of this research was to analyze the characteristics of teachers' questionings in the geometry field and suggest the characteristics of teacher questioning to enhance students' mathematical creativity. Teacher questioning plays a role to students' mathematical achievements, mathematical thinking, and their attitudes toward mathematics. However, there has been little research on the roles of teacher questioning on students' mathematical creativity. In this research, researchers analyzed teachers' questions concerning the concepts of triangles in the geometric areas of 4th grade Korean revised 2007 mathematics textbooks. We also analyzed teachers' questionings in the three lessons provided by the Jeju Educational Internet Broadcasting System. We classified and analyzed teachers' questionings by the sub-factors of creativity. The results showed that the teachers did not use the questionings that appropriately enhances students' mathematical creativity. We suggested that teachers need to be prepared to ask questions such as stimulating students' various mathematical thinking, encouraging many possible responses, and not responding with yes/no. Instead, teachers need to encourage students to explain the reasons of their responses and to take part in learning activities with interest.

  • This paper discusses techniques for embedding data into 3D polygonal models of geometry. Much researches of Watermarking had been gone as element technology of DRM (digital rights management). But, few research had gone to 3D polygonal model. Most research is limited at text document, 2D image, animation, music etc. RP system is suitable a few production in various goods species, and it is used much in industry to possible reason that produce prototype and find error or incongruent factor at early stage on design in product development childhood. This paper is research about method that insert watermark in STL ( stereolithography) file that have 3D shape model. Proposed algorithm inserts watermark in normal vector region and facet's interior region of 3D shape data. For this reason, 3D shape does not produce some flexure and fulfill invisibility of watermark. Experiment results that insert and extract watermark in normal netter region and facet's Interior region of 3D shape data by proposed algorithm do not influence entirely in 3D shape and show that insertion and extraction of watermark are possible.

  • This study aimed to analyze the characteristics of the bibliographic description of ISBD Consolidated edition published in 2011 and to grasp the considerations in applying the rules of ISBD consolidated edition to KCR4. For achieving this, the four aspects were analyzed such as the description area and data elements, the resource types, the punctuation, and the order of the elements of ISBD Consolidated edition(2011). The characteristics of ISBD Consolidated edition are as follows. First, the content form and the media type area are added in new 0 area and elements are designated by mandatory to confirm to FRBR. Second, content form, content qualification and media type replaced GMD in title and statement of responsibility area. Third, the prescribed punctuations were retained even when this results in double punctuation, and individual square brackets were preferred than entire square brackets when using square brackets to all elements in same area. Fourth, the order of elements in description was set out by patterns of data elements in areas, therefore could reduce the confusion of the order of elements. ISBD Consolidated edition as an international standard would make various rules to maintain the uniformity, but also respects the bibliographic practices of individual countries. Therefore, each country must revise its own rule to conform the ISBD Consolidated edition as well as reflect its unique situation. In Korea, since KCR4 was developed based on the previous edition of ISBD, it should be revised to confirm to the ISBD Consolidated edition. Therefore, this study is expected to contribute to the revision of KCR4.

  • 재무관리의 모든 영역을 완벽하게 이해하기 위하여는 기업재무관리와 투자론을 비롯하여 금융산업 전체에 대한 연역적 방법에 의한 이론의 정립과 실증분석을 통한 이론의 정립이 관건이라 할 수 있다. 이 논문에서는 실증 분석을 수행함에 있어 우리나라에서 활발하게 논의가 진행되지 않는 시계열분석의 영역을 살펴보았다. 그것은 이와 같은 분야를 천착해 봄으로써 이 분야가 재무관리에 대한 통찰력과 현실 적합성의 판단력을 배양하는데 큰 공헌을 할 수 있으리라는 믿음 때문이다. 이 논의를 통하여 시계열 분석에 대한 활발한 연구가 진행되기를 기대하고 있다. 시계열 확률과정에 대한 재무관리이론을 연역적으로 도출하기는 용이하지 않다. 시계열 분석에서 제시되는 여러 방법론을 재무관리의 시계열에 적용하여 그 시계열의 성질과 특성을 파악하면 그것이 그대로 현실에 적용될 수 있을 것이다. 이러한 연구의 결과는 어떤 형태로든 연역적 방법에 의한 이론의 정립에 깊은 영향을 미칠 것이다. 뿐만 아니라 연속시간의 틀과 이시적(異時的) 양태하(樣態下)에서 많은 재무관리 모형들이 개발되고 있으며, 동태적 상황을 해명하는 의도에서 이 모형들이 연구되고 있는 만큼 시계열 분석은 이 분야에 직접적으로 이용될 수 있다. 시계열 분석에서 제시된 많은 모형들이 재무관리의 실증적 현상을 설명하는데 효과적으로 활용될 수 있다. 뿐만 아니라 현재 연역적으로 개발된 모형들이 설명할 수 없는 부분을 시계열 분석이 직접적으로 해명할 수 있는 능력을 확보하고 있음도 제시되었다. 증권의 현가모형(現價模型), 이자율의 기간구조, 효율적 시장가설도 주가의 변동성 등은 시계열 분석의 다양한 기법을 사용하여 검증되어야 하며, 이 경우 특히 분산의 추정방법을 여러 측면에서 개발해 야 할 것이다. 시계열 분석에서는 두개 또는 그 이상의 기법을 하나로 통합하는 방법이 있을 수 있다. ARIMA와 ARCH가 결합되는 것을 본 바 있다. 구조적(構造的) 변화(變化)(structural change)모형(模型)과 ARCH의 결합도 가능하다. 다른 분야로서는 변동성(變動性)에 관한 연구이다. 변동성(變動性)에 관한 연구는 variance bounds test에 한정된 감이 있으나 정보와 변동성의 관계가 중요시되고 있는 만큼 정보집합과 시계열 분석 기법의 결합은 변동성의 연구에 새로운 지평을 열어줄 것으로 보인다. 따라서 정보집합의 형성에 따라 새로운 추정방법이 개발될 여지가 풍부하다.
