  • It is difficult to classify tidal flat surface that is composed of a mixture of mud, sand, water and microphytobenthos. We used a Linear Spectral Unmixing (LSU) method for effectively classifying the tidal flat surface characteristics within a pixel. This study aims at 1) detecting algal mat using LSU in the Saemangeum tidal flats, 2) determining a suitable end-member selection method in tidal flats, and 3) find out a habitual characteristics of algal mat. Two types of end-member were built; one is a reference end-member derived from field spectrometer measurements and the other image end-member. A field spectrometer was used to measure spectral reflectance, and a spectral library was accomplished by shape difference of spectra, r.m.s. difference of spectra, continuum removal and Mann-Whitney U-test. Reference end-members were extracted from the spectral library. Image end-members were obtained by applying Principle Component Analysis (PCA) to an image. The LSU method was effective to detect microphytobenthos, and successfully classified the intertidal zone into algal mat, sediment, and water body components. The reference end-member was slightly more effective than the image end-member for the classification. Fine grained upper tidal flat is generally considered as a rich habitat for algal mat. We also identified unusual microphytobenthos that inhabited coarse grained lower tidal flats.

  • The purpose of this study is to evaluate the effectiveness of the theme collection service in public library from the user's perspective. To this end, based on prior research, the effect elements of the theme collection were derived from the service use, librarian, and library level. A questionnaire survey was conducted on 294 users of A public library. The collection satisfaction of users who know the theme collection was higher than those who did not, and showed high recognition for the satisfaction with the use of new and unexpected books. In addition, it was found that the positive recognition tended to be high among users who have been using the library for a long time and frequently use the library service. Based on the users' perception and evaluation of the theme collection, the direction of development of the theme collection service was suggested in terms of collection development, collection use and information service, user-centered classification, and awareness improvement of libraries and librarians.

  • This study is to suggest the revitalization plan of the medical school libraries in the future, on the basis of analysis for the overall operation situation of the medical school libraries among the medical libraries. So based on the website, it is divided into 1) whether independent homepage exists, 2) service target, 3) books, 4) classification system, 5) manpower, 6) facilities (area, number of seats available), 7) equipment (pc, printer, copy machine, etc.), 8) services, and then analyzed. Consequently, as the ways to revitalize the medical libraries, firstly, it is necessary to establish legal standards and develop guidelines for the medical school library's books, sizes, librarians, etc. Secondly, establishing a cooperative community network between medical school libraries is necessary. Thirdly, policies such as support at the national level, specialization education of librarians, development of operational guidelines, and activation of inter-library networks are needed to revitalize the medical school libraries. It is also expected that research on the actual situation of the medical libraries should be conducted at the national level or at the level of the association of medical libraries.

  • This paper presents a new edge-protection algorithm and its very large scale integration (VLSI) architecture for block artifact reduction. Unlike previous approaches using block classification, our algorithm utilizes pixel classification to categorize each pixel into one of two classes, namely smooth region and edge region, which are described by the edge-protection maps. Based on these maps, a two-step adaptive filter which includes offset filtering and edge-preserving filtering is used to remove block artifacts. A pipelined VLSI architecture of the proposed deblocking algorithm for HD video processing is also presented in this paper. A memory-reduced architecture for a block buffer is used to optimize memory usage. The architecture of the proposed deblocking filter is verified on FPGA Cyclone II and implemented using the ANAM 0.25 ${\mu}m$ CMOS cell library. Our experimental results show that our proposed algorithm effectively reduces block artifacts while preserving the details. The PSNR performance of our algorithm using pixel classification is better than that of previous algorithms using block classification.

  • Although university libraries run by the subject-oriented serviec systems are increasing more and more, many problems are emerging as a result of tying out the subject classification of the sources without an enough advance knowledge, consideration of reality, and the study about effective management of subject-oriented sum system. Through the research of 37 university libraries run by the system of subject-oriented service, it was proved that for the effective subject-oriented service system, the reasonable classification of the subjects, considering the form and structure of the building, the number of users on each subject and the organization of the collection, and the subject librarians, who would take charge of subject-oriented service systems are indispensable. Therefore, the subject-oriented service system to be rooted strongly, the role model of the subject-oriented service system adequate to the reality of Korean university libraries should be developed, and the efforts of the people on the spot such as acquiring enough supports and training of the subject librarians should be arranged.

  • Since the Korean government has decided to apply the policy of BIM (Building Information Modeling) to the entire construction industry, it has experienced a positive trend in adoption and utilization. BIM can reduce workloads by building model objects into libraries that conform to standards and enable consistent quality, data integrity, and compatibility. In the domestic architecture, civil engineering, and the overseas landscape architecture sectors, many BIM library standardization studies have been conducted, and guidelines have been established based on them. Currently, basic research and attempts to introduce BIM are being made in Korean landscape architecture field, but the diffusion has been delayed due to difficulties in application. This can be addressed by enhancing the efficiency of BIM work using standardized libraries. Therefore, this study aims to provide a starting point for discussions and present a classification system for objects and attribute information that can be referred to when creating landscape libraries in practice. The standardization of landscape BIM library was explored from two directions: object classification and attribute information items. First, the Korean construction information classification system, product inventory classification system, landscape design and construction standards, and BIM object classification of the NLA (Norwegian Association of Landscape Architects) were referred to classify landscape objects. As a result, the objects were divided into 12 subcategories, including 'trees', 'shrubs', 'ground cover and others', 'outdoor installation', 'outdoor lighting facility', 'stairs and ramp', 'outdoor wall', 'outdoor structure', 'pavement', 'curb', 'irrigation', and 'drainage' under five major categories: 'landscape plant', 'landscape facility', 'landscape structure', 'landscape pavement', and 'irrigation and drainage'. Next, the attribute information for the objects was extracted and structured. To do this, the common attribute information items of the KBIMS (Korean BIM Standard) were included, and the object attribute information items that vary according to the type of objects were included by referring to the PDT (Product Data Template) of the LI (UK Landscape Institute). As a result, the common attributes included information on 'identification', 'distribution', 'classification', and 'manufacture and supply' information, while the object attributes included information on 'naming', 'specifications', 'installation or construction', 'performance', 'sustainability', and 'operations and maintenance'. The significance of this study lies in establishing the foundation for the introduction of landscape BIM through the standardization of library objects, which will enhance the efficiency of modeling tasks and improve the data consistency of BIM models across various disciplines in the construction industry.
