This study is an attempt at developing an organizational model for collection development a n.0, pplicable to Korean university libraries at their present stage of development. An emphasis is placed on the discussion of the 'subject a n.0, pproach' as compared to 'functional a n.0, pproach' in collection development work. The case history of Pusan National University Library is extensively used. The proposed collection development model consists of the following elements : - To form a collection development team and to place under the team leader subject bibliographers as follows: Bibliographer for Serials Bibliographer for Humanities Bibliographer for Social Sciences Bibliographer for Sciences and Technologies - Collection development team could operate as a separate department or as part of other departments, i. e., Deputy Director's office, Acquisitions and Processing Department, or Resources Management Department. - Collection development team takes up the responsibility for policyrelated collection work, i. e., budget allocation, evaluation of existing collection, building core collection, preservation, weeding and cooperation. - Designated certified librarians located at the(planned) subject libraries take up the responsibility for selection. Subject bibliographers cooperate with selection librarians and coordinate their work. - Certified librarians at the Acquisitions and Processing Department are assigned subject areas. They operate as acquisitions librarian and processing librarian simultaneously with their assigned subject materials.

Urdu is a widely spoken language in the Indian subcontinent with over 300 million speakers worldwide. However, linguistic advancements in Urdu are rare compared to those in other European and Asian languages. Therefore, by following Text Retrieval Conference standards, we attempted to construct an extensive text collection of 85 304 documents from diverse categories covering over 52 topics with relevance judgment sets at 100 pool depth. We also present several applications to demonstrate the effectiveness of our collection. Although this collection is primarily intended for text retrieval, it can also be used for named entity recognition, text summarization, and other linguistic applications with suitable modifications. Ours is the most extensive existing collection for the Urdu language, and it will be freely available for future research and academic education.

It has been reported that destruction test by core collection is the most reliable of the structural concrete strength in present building construction field. But it causes low efficiency by damage and cutting in structure due to the core collection. It also has some problems in repairing. Additionally in case of strength test with management specimen, different environment compared to the structure environment cause problems about estimation precise structure strength. Therefore, it is required to develop structure direct strength test that has test values and credibility above the ones obtained by core specimen collection strength test and seasonal specimen test to suggest a reasonable and practical management method of structural concrete.

The purpose of this study is to numerically evaluate the collection performance of an ultra-small Lapple cyclone separator for 1~10 ㎛ particles introduced at flow rate of 10 L/min. The numerical evaluation reveals that a static pressure drop occurs more dominantly inside of the cyclone separator than at the inlet and the vortex finder. Also a fluid flow in the cyclone separator is confirmed to have a helical structure heading upward in the center of cyclone separator and downward in the vicinity of wall. The investigation on dust collection efficiency of the Lapple cyclone separator shows that particles of 4~8 ㎛ diameters are collected at very lower efficiency than other sizes. Then, the cut-point diameter of the cyclone separator is 1.48 ㎛.

NAND flash memory has unique characteristics like as 'out-place-update' and limited lifetime compared with traditional storage systems. According to out-of-place update scheme, a number of invalid (or called dead) pages can be generated. In this case, garbage collection is needed to reclaim invalid pages. Because garbage collection results in not only erase operations but also copy operations of valid (or called live) pages to other blocks, many garbage collection techniques have proposed to reduce the overhead and to increase the lifetime of NAND Flash systems. This techniques sometimes select victim blocks including cold data for the wear leveling. However, most of them overlook the cost of selecting victim blocks including cold data. In this paper, we propose a garbage collection technique named CAPi (Cost Age with Proportion of invalid pages). Considering the additional overhead of what to select victim blocks including cold data, CAPi improves the response time in garbage collection and increase the lifetime in memory systems. Additionally, the proposed scheme also improves the efficiency of garbage collection by separating cold data from hot data in valid pages. In experimental evaluation, we showed that CAPi yields up to, at maximum, 73% improvement in lifetime compared with existing garbage collections.

The purpose of this study is to find out the image according to formative properties of hat and garment in the fashion collection. For the study, the 96 stimuli found frequently in fashion collection from the S/S season of 1998 to the F/W season of 2004 were selected. Sets of stimulus and response scales (7 point semantic) were used as experimental materials. The stimuli were 96 pictures with the types of hat(4), the lengths of hair(3), the types of garment(3), the relations between the color of garment and hat(4), and the materials(4) and patterns of garment(2). The subjects were 415 women college students majoring fashion design related fields and living in Seoul and Gyeongsangnam-do. As statistical methods for data analysis, Factor Analysis, ANOVA test, and LSD test were used. The items of the adjectives were classified into 5 image dimensions; attractiveness, gracefulness, concentration, cuteness, and hardness and softness. Among these factors, each dimensional image was affected by formative properties of hat and garment. The image of a hat-wearer was perceived differently according to the hair style and the formative properties of hat and garment even if the type of hat was same.

There has been some research in Korea on test collections for evaluation of information retrieval (IR) systems. The test collections constructed as an outcome from the research have provided a starting point and opportunities to test Korean IR systems in an objective manner. However, they are well short of the standard practice in the broader IR community in that they are small in their size and usually unbalanced in terms of the characteristics of the documents and the queries (such as the subject domains). In this article, we describe our research effort to alleviate this problem and the resulting test collection, called HANTEC (Hangul TEst Collection). HANTEC is balanced in terms of the subject domains, document lengths, and user types, and currently consists of 120,000 documents divided into three groups: general area, social science area and scienceltechnology area. The 30 queries in the collection are grouped into the same three areas in one dimension and into three distinct user groups in the other dimension.

To improve the dCollection system, it is suggested that the usability tests of the dCollection system are needed to find out whether submitters or IR managers are satisfied with the system or not. For the usability evaluations, we used sixty participants, thirty for its management module and thirty for its submit and retrieval modules and for its test constructed the five evaluation indicators including architectural/visual clarity and effectiveness. Based on the results of the usability tests, some improvements in terms of supportiveness, usefulness and visual clarity were suggested.
