Noise occurs in the process of obtaining, transmission, and processing in image processing systems and these noises lower the resolution of image and cause visual errors. Currently, a representative filter to remove salt and pepper noise is SMF(standard median filter) but it is inadequate in preserving edge as the noise field expands. Therefore, for salt and pepper noise enviroment, the study suggested and algorithm that are places with original pixel when the central pixel is non-noise and process by applying weighted value on areas with less local mask pixel changes when there is noise.

This paper proposes the use of an adaptive Wiener filter for edge-preserving image filtering. Images are partitioned into a set of blocks of pixels which is divided into five subsets of blocks according to their edge contents and orientations. Each subset of blocks is used to define a covariance matrix, from which a Wiener filter is derived. Five covariance matrices and Wiener filters are thus obtained. An image-block classifier using the five sets of covariance matrices of the class is designed to classify each incoming block of pixels according to its edge content in the presence of noise. Experimental results are included to verify the usefulness of the proposed method.

This study examines the status quo of Korean archives and records management from the Governmental as well as professional activities for the development of the field in relation to the new legislation on records management. Among many concerns, this study primarily explores the following four perspectives: 1) the Government Archives and Records Services; 2) the Korean Association of Archives; 3) the Korean Society of Archives and Records Management; 4) the Journal of Korean Society of Archives and Records Management. One of the primary tasks of the is to build the special depository within which the Presidential Library should be located. As a result, the position of the GARS can be elevated and directed by an official at the level of vice-minister right under a president as a governmental representative of managing the public records. In this manner, GARS can sustain its independency and take custody of public records across government agencies. made efforts in regard to the preservation of paper records, the preservation of digital resources in new media formats, facilities and equipments, education of archivists and continuing, training of practitioners, and policy-making of records preservation. For further development, academia and corporate should cooperate continuously to face with the current problems. has held three international conferences to date. The topics of conferences include respectively: 1) records management and archival education of Korea, Japan, and China; 2) knowledge management and metadata for the fulfillment of archives and information science; and 3) electronic records management and preservation with the understanding of ongoing archival research in the States, Europe, and Asia. The Society continues to play a leading role in both of theory and practice for the development of archival science in Korea. It should also suggest an educational model of archival curricula that fits into the Korean context. The Journals of Records Management & Archives Society of Korea have been published on the six major topics to date. Findings suggest that "Special Archives" on regional or topical collections are desirable because it can house subject holdings on specialty or particular figures in that region. In addition, archival education at the undergraduate level is more desirable for Korean situations where practitioners are strongly needed and professionals with master degrees go to manager positions. Departments of Library and Information Science in universities, therefore, are needed to open archival science major or track at the undergraduate level in order to meet current market demands. The qualification of professional archivists should be moderate as well.

This study aimed to present practical strategies for libraries in South Korea, including the National Central Library, to effectively respond to the new challenges of the digital era by systematically comparing and analyzing the status of online material collection and services of libraries both domestically and abroad. To achieve this, we sought to understand the cases and service status of online material collection in major foreign libraries and to derive directions and usage plans for our libraries based on the analysis of these foreign libraries' online material collection status. As a result of this research, it was found that the National Central Library needs to explore various strategies for expanding online material collection, including the proper collection and preservation of web resources that are being created and deleted, as well as expanding openness and utilizing archives. Secondly, as a central institution for future national information resources, it is necessary to establish a strategy for smoothly collecting, preserving, and servicing vast and complex web resources. Thirdly, there is a need to explore ways to implement a national-level web archive that can systematically collect, preserve, and utilize all web resources in our country. In the long term, it should be improved into a national platform capable of systematically collecting, preserving, and utilizing various types of web resources.

일본 문화청 소속의 정부조직이었던 나라국립문화재연구소가 국가조직의 행정개혁에 따라 현재의 독립행정법인 나라문화재연구소로 변혁하면서 나타나고 있는 여러가지 상황에 대해서 살펴보고자 한다. 나분켄은 동아시아에서도 잘 알려진 국보 호류지금당벽화의 소실이 문화재 분야의 큰 문제로 부각되면서 종합적이고 학술적인 문화재의 연구 보호 종합기관의 설립 필요성에 의해 만들어진 기관이었다. 연구분야에서 보면 초기에는 역사, 건축, 미술공예, 정원, 유적 등 다양한 분야에서 출발했으나 나라지역의 헤이조큐 유적보존 문제가 주요 이슈로 떠오르면서 매장문화재의 발굴 중심으로 그 역할이 강화되는 변화를 겪에 되었다. 그러나 선사고고학이 아닌 역사고고학이 중심이었기 때문에 건축사나 정원사, 보존과학 등 서로 다른 학문이 융합하여 연구할 수 있는 강점이 강화되어 설립목적은 견지하면서 변모하였다. 독립행정법인으로의 변화는 1999년의 제145차 통상국회에서 "독립행정법인통칙법"이 성립되면서 부터였다. 독립행정법인의 취지는 독립 운영하는 쪽이 효율적인 부분을 분리시켜 법인격을 가진 기관으로 바꾸면서 운영교부금을 주무관청으로부터 받아 사용처를 독자적 재량에 맡기면서 이윤을 올릴 수도 있게 한 것이다. 또한 조직과 인사의 자율성을 보장받는 장점도 있으나 평가시스템이 되입되는 정신적 부담도 공존하게 된다. 즉, 민간 방법의 도입에 따라 국가의 부담을 경감하고자하는 의미가 내재되어있다. 나분켄의 독립행정법인화는 동시에 도쿄문화재연구소의 통합을 수반하게 되었다. 도분켄은 원래 미술공예품을 중심으로한 동산문화재 연구와 보존과학부분에 충실한 조직이었으므로 부동산문화재 중심의 나분켄과 통합에 우려의 목소리가 있었다. 그러나 불행중 다행으로 다카마쓰즈카 고분벽화의 열화문제와 키토라 고분 벽화의 보존문제로 인하여 전무후무한 협업연구가 진행되고 양 연구소의 역량을 결집할 수 있는 계기가 되었다. 결론적으로 말하자면, 독립행정법인화는 매년 예산을 중기계획이나 연도계획과 정합성을 유지하면서 독자적인 판단을 통해 편성하는 등 극히 유연한 대응이 가능하다는 장점을 가지고 있는 반면, 문화재 보존을 위한 연구라는 공공적인 목적을 가진 조직이 정부의 의도대로 독자적으로 이윤을 올리는 사업을 확립하여 국가의 부담을 경감하는 방향으로 나아갈 수 있는가라는 부분에서는 의심할 여지가 남아 있다.

The main issue of noise reduction of image is how to preserve edge and reduce noise. Usually, The Wiener falter is used for this purpose. But the conventional Wiener filter cannot remove noise well in both edge and smooth region due to the single size estimation window. In addition, it ignores the correlation between pixels. In this paper, we propose a new noise reduction algorithm, in which adaptive estimation window is used according to property of smooth region and edge region. In order to make edge more clear, directional Gaussian mask and directional estimation window combines to the Wiener filter according to direction of edge. From the simulation results, it can be seen that the proposed algorithm showed improves performance in both PSNR arid subjective evaluation

After inspecting ground surface or excavating cultural heritage site, the government can take measures for the preservation of buried cultural heritage based on the related law. It means that the provisions complement the limitation of current cultural heritage management system by extending the scope of cultural heritage to be preserved. But we neither have set any matters about implementing the measures for preservation of the buried cultural heritage, nor manage the heritage and its surroundings after implementing the measures. Due to these insufficiency of the law, there arise several problems in the field. For example, the measures for preservation are not complete, or preserved cultural heritage is damaged due to inappropriate management. We have to resolve the problems in order to accomplish the original purpose of taking measures for preservation of the heritage. First, it is necessary to make sure of the legal status of preserved buried cultural heritage, to establish the standards to decide whether to preserve it or not. We need to have regulations by law or internal rule on the daily management, who should manage it, what and how the manager should manage. It is also important for local residents to take an active part in preserving and utilizing the cultural heritage as the owner. Through building up the foundation mentioned above, the meaning and value of preserved buried cultural heritage can be expanded widely.

대규모 개발사업을 시행함에 있어 우리는 종종 무의식적으로 토양층을 교란시키게 된다. 식물 성장에 있어 토양은 영양분을 공급하는 중요한 역할을 하고 특히 토양 중 표토층은 식물 생장에 필요한 많은 영양성분을 갖고 있으므로 토양층의 파괴는 식재된 수목의 하자와 직접 연결된다. 살아있는 식물을 다루는 조경공사에서는 공사 후 높은 하자율을 걱정하기에 앞서 수목의 원활한 활착을 위해 토양을 건강하게 유지하도록 노력해야 한다. 본 연구에서는 수목과 토양의 생리학적 관계 및 토양의 기본적인 성질과 표토의 중요성, 표토의 특성을 유지하는 방안 등에 대해 고찰하고 사례연구로 한국토지공사에서 시행한 용인 동백지구의 표토 활용사례를 검토하여 문제점을 파악하고 보다 효과적인 표토층 보존을 위한 방향을 제시하고자 한다. 수목의 성장률, 건강도, 수형 등은 직접적으로 토양의 질과 연결되고 양질의 토양은 수목의 원활한 생장을 가져와 결국 수준 높은 경관을 형성할 수 있게 된다. 본 연구를 통해 수목과 토양의 생리학적 관계를 파악하고 수목의 성장에 적정한 환경을 제공함으로써 불량한 토양으로 인한 수목의 하자율을 사전에 방지하고 수목의 건강성을 유지하는 방안 설정에 도움이 되고자 한다.
