This study concerns Sama Pangmok which is in the possession of Harvard-Yenching Library, Harvard University, USA. Sama Pangmok is the archive of Saengwon Chinsa Examination(the licentiate examination) which is the preliminary test for main civil service examination. And it is the list of the names of the applicants who passed this examination. This examination were conducted from the days of lauching of Chosun as a new nation to the days of Kabo Kyungjang(the 1894 reform). While this examination was conducted 230 times, not all but 186 of the resultant lists are available. Of these 186 lists, this library posses 47 titles. My study of the existing dissertation on the possession of titles by Harvard-Yenching Library, 7 titles where in possession of the same library in 1968 and 5 ones in 190. It is the main objective of this study to clarify the possession of this library and correct the past errors in indication of possession of titles by this library. For this purpose, I conducted a study on Saengwon Chinsa Examination and Sama Pangmok, which could be the historical background of this study. This was followed by research on the bibliographical aspect of Sama Pangmok and the research on the situation concerning this Library's possession of the same lists. Lastly, the analysis of the special feature of Sama Pangmok possessed by this Library was conducted. It is expected that the result of this research will be applied to the practical research of the history of civil service examinations and the old and rare books overseas in the future.

This paper describes the construction of knowledge data retrieval management system based on medical image CT. The developed system is aimed to improve the efficiency of the hospital by reading the medical images using the intelligent retrieval technology and diagnosing the patient 's disease name. In this study, the medical image DICOM file of PACS is read, the image is processed, and feature values are extracted and stored in the database. We have implemented a system that retrieves similarity by comparing new CT images required for medical treatment with the feature values of other CTs stored in the database. After converting 100 CT dicom provided for academic research into JPEG files, Code Book Library was constructed using SIFT, CS-LBP and K-Mean Clustering algorithms. Through the database optimization, the similarity of the new CT image to the existing data is searched and the result is confirmed, so that it can be utilized for the diagnosis and diagnosis of the patient.

Relevance judgment is important in terms of improving the effectiveness of information retrieval systems, and it has been dominant for users to search and use images utilizing internet and digital technologies. However, in the field of image retrieval, there have been only a few studies in terms of identifying relevance criteria. The purpose of this study aims to identify and characterize the non-relevance criteria from the failed image searches. In order to achieve the purpose of this study, a total of 135 participants were recruited and a total of 1,452 criteria items were collected for this study. Analyses and identification on the data set found thirteen criteria such as 'topicality', 'visual content', 'accuracy', 'visual feature', 'completeness', 'appeal to user', 'focal point', 'bibliographic information', 'impression', 'posture', 'face feature', 'novelty', and 'time frame'. Among these criteria, 'visual content' and 'focal point' were introduced in this current study, while 'action' criterion identified in previous studies was not shown in this current study. When image needs and image uses are analyzed with these criteria, there are distinctive differences depending on different image needs and uses.

A factorization-based 3D reconstruction system is realized to recover 3D scene from an image sequence. The image sequence is captured from uncalibrated perspective camera from several views. Many matched feature points over all images are obtained by feature tracking method. Then, these data are supplied to the 3D reconstruction module to obtain the projective reconstruction. Projective reconstruction is converted to Euclidean reconstruction by enforcing several metric constraints. After many triangular meshes are obtained, realistic reconstruction of 3D models are finished by texture mapping. The developed system is implemented in C++, and Qt library is used to implement the system user interface. OpenGL graphics library is used to realize the texture mapping routine and the model visualization program. Experimental results using synthetic and real image data are included to demonstrate the effectiveness of the developed system.

For this article, we conducted frequency analysis, topic modeling, and network analysis on eleven texts related to collection development policy found in the National Library of Korea. We deduced the main keywords related to collection development policies and analyzed the relationship between them. We subsequently conducted a pie coefficient analysis to identify the characteristics of collection development policies of university libraries and public libraries by category. The results showed that keywords such as "material," "library," "collection development," "user," and "collection" were the main keywords in frequency analysis and network centrality. Meanwhile, the pie coefficient analysis revealed that keywords such as "university," "construction," "student," "target," and "cost" were prevalent in university libraries, indicating that the academic needs of users and the discussion of digital resources were primary issues, while keywords related to the information needs of various user groups-including "adults," "survey," "feature," and "religion" -appeared in public libraries.

Nowadays, the World Wide Web (WWW) has become an important resource of timely information for the information-related people such as information scientists, librarians, and students in Library and Information Sciences area. They are information professionals who navigate the information on the internet. Also, they need to be information providers who build a WWW homepage. This paper is a study of the necessity, preparation, and building WWW Homepage files for school of Library and Information Sciences in the age of competition among disciplines. It is particularly focused on the colleges and universities in Republic of Korea (ROK) and North America area. The purpose of this study is to provide various kinds of reference information to prepare a homepage in the future as utilizing information on the internet effectively. Even though a Web page was necessary for a school of Library and Information Sciences to show news, and introduce the purpose of the disciplines and the curriculum of the school, and the professors of a class etc., it was not well-prepared yet in ROK. However, a web page was used well enough and prosperous in North America area (Canada, the United States, and Puerto Rico) comparatively. Those web pages were analyzed and studied to prepare for a good designing of homepages for school of Library and Information Sciences in Korea and for the age of competition among disciplines in this paper. Suggestions for designing a good homepage and guidelines for preparing a best one were studied after both reviewing literature and utilizing experiences by the author who currently serves in the School of Library and Information Sciences in Keimyung University and builds homepage for the school. As a result, the major suggestions are ; premiered, and they are as follows: (1) English version of a homepage is necessary, (2) Provide a multimedia presentation about the nature of a school (3) Incorporate a place to let people make suggestions on the contents (of a homepage), (4) Bear in mind that potential users must be familiar with abbreviations you used, (5) Absolutely do not use abbreviations that may make the content more difficult to understand, (6) Add a feature on the every single page that will take the user back to the main page, (7) Use clear, short and well-structured sentences and remember to divide text into paragraphs, (8) Date with a creation or modification date in the homepage to indicate the updated date, (9) Being a multimedia environment, use colors effectively (the guidelines were also suggested), and (10) Put colleges' name into the title of bookmarks to find out them easily.

This is an analytical study on Munheongak (文獻閣) and it's catalogue. The major objective of the study is to get a recognition of Munheongak under the culture of Sukjong (肅宗) period in Korean library history. Most of early studies made on such a category have been concentrated on Jiphyunjeon (集賢殿), Hongmungwan (弘文館), Kyujanggak(奎章閣) and their backgrounds. In this study, the author has invest gated Kungwolji (宮闕志), Munheongakseomg (文獻閣書目) and other materials related to this subject. The findings of the study can be summarized as follows: 1. Munheongak was established by king Sukjong in the 26th year of his reign. According to some records of Kungkwolji, the reason of establishment of the library was to arrange the collection in the Sango (相庫) consisted of various kinds of materials. In case of books, most of them turned out to be Korean books. 2. Munheongak was sited to the estern side of Kyunghyundang (景賢堂), which was located on the Kyungdeokgung (慶德宮). After Youngjo (英祖) the place was called Kyungheuigung (慶熙宮) so as to avoid the name of the precedent king. But these days, both the buildings are not to be found. 3. After its establishment, the library could not play the role as a library because of the then political situation and sectionalism. During the period of the revival of the learning from Youngjo till Jeongjo(正祖) the function of the library was in a stagnant state. Kyujanggak played the part in its place. 4. Referring to the collection management, the Munheongakseomog is equipped with 101 titles, 2,525 volumes, which are arranged by means of the traditional Chinese classification system. 5. The classification scheme is based on the traditional Chinese classification system which might divide all subjects into four categories such as: Confucian classics division, Historical documents division, Master's division, and Collection of literature division. Some illustrations reveal that the classification system was directly influenced by Seogoseomg (書庫書目) : the influence reflected in the classes for the translated literature and writings, poems, genealogy about kings, etc. But some subdivisions such as a class of Annals, Historical Epcerpts were omitted in the classification scheme, which did not strike the balance in the system in terms of the present theory of classification. Most of bibliographical descriptions were also influenced by Seogoseomog but some elements were partly omitted. 6. The special feature of the collection building is the absence of books in Collection of literature division except only three kinds of books in examining the Munheongakseomog. Since this is rather a comprehensive study for such aspects as historical backround, catalogue, and cultural environment of Munheongak and its related record, it is advised that further and additional research should be made.

This paper presents design and verification of a face detection hardware for real time application. Face detection algorithm detects rough face position based on already acquired feature parameter data. The hardware is composed of five main modules: Integral Image Calculator, Feature Coordinate Calculator, Feature Difference Calculator, Cascade Calculator, and Window Detection. It also includes on-chip Integral Image memory and Feature Parameter memory. The face detection hardware was verified by using S3C2440A CPU of Samsung Electronics, Virtex4LX100 FPGA of Xilinx, and a CCD Camera module. Our design uses 3,251 LUTs of Xilinx FPGA and takes about 1.96${\sim}$0.13 sec for face detection depending on sliding-window step size, when synthesized for Virtex4LX100 FPGA. When synthesized on Magnachip 0.25um ASIC library, it uses about 410,000 gates (Combinational area about 345,000 gates, Noncombinational area about 65,000 gates) and takes less than 0.5 sec for face realtime detection. This size and performance shows that it is adequate to use for embedded system applications. It has been fabricated as a real chip as a part of XF1201 chip and proven to work.

This study examined the historical background and structural characteristics of the UDC(Universal Decimal Classification) standard edition which has been created from the entire content of the Master Reference File database. We made a comparison of the structural characteristics between UDC standard edition and Korean abridged edition. UDC is a hybrid of two kinds of documentary classification scheme, that is enumerative and analytico-synthetic, and its structure reflects this feature. It is found that UDC standard edition extended the universality and synthetic method using its auxiliary tables compare to Korean abridged edition.
