In Digital Contents Computing Environment, information such as register, cache memory, and network information are hard to make certain of a real-time collection because such information collection are easily modified or disappeared. Thus, a collection of information is one of important step for computer forensics system on Digital Contents computing. In this paper, we propose information collection module, which collects variable information of server system based on memory mapping in real-time.

The purpose of this paper is to find out how the education for collection development has been changed and what are the contents of the collection development-related courses. The author tried to search some historical backgrounds on how selection of books became collection development and management. As for the ducation for collection development, the changes the course titles dealing with collection development were surveyed, and the contents of the courses provided by the Departments of Library and Information Science were analyzed. It was found out that though the course titles have been changed from selection of materials collection development, the contents showed their emphases on such selection-oriented topics as selection tools and acquisitions. It is concluded that as far as the contents are concerned, most of the important components for collection development have been taught. Based on the findings, a few suggestions including that there should be efforts to narrow the gap between the theories taught at library schools and the practices performed by librarians are recommended.

The collection management paradigm has drastically changed since the emergence of collection management activities on the internet. Due to the technological development of web, web has become the newly open field as a useful tool to facilitate collection management transactions. The purpose of this study is, by evaluating web sites of the university library’s collection management in United States, to construct the contents of collection management web site. To fulfill the purpose, 6 categories for the contents of the collection management web site are suggested. The result of this study can be used as the basic data for researching of collection management web site. Web site is playing a role of stepping up its activities and informing useful information on its selection tool and collection development policy.

The discharge and the collection efficiency characteristics of an electrostatic precipitator have been studied under various operating conditions. The specific resistivity of pulverized coal dust was about 1013∼1014[${\Omega}{\cdot}cm$] and reached the maximum value of 6${\times}$1013[${\Omega}{\cdot}cm$] at 150[$^{\circ}C$]. Back corona has been occurred as dust contents and gas temperature increase. In the case of back corona occurrence, collection effciency decreased rapidly. This problem has been solved by increasing moisture contents. Experimental results showed that collection efficiency of the full wave voltage was higher than that of the pulse wave voltage. The modification parameter k of the collection efficiency equation was about 0.42.

University library must have a substantial collection development policy, by which the short and long term plannings are set up to meet the goals of university education and to support university function. Only when university library organizes collection building based on the well-planned policy, can it establish the systematic collection building, which can satisfy users, support continuity of work, use budget efficiently, and solve the space problem by with-drawing the materials. But most Korean university libraries, contrary to many foreign cases, don't have proper systematic collection development policy or guideline that controls overall library work from planning the collection of materials to evaluating and preserving them. Questionaire on whether university library has collection development policy or guideline was answered positively by only 6 cases out of 57 cases, which is just 10.5 percent. Even in cases that they have a guideline, the content of the copied guideline they sent was confined to acquisition, which is just a part of collection development. Collection development is a statement needed to set up long and short term plannings in consideration of the aims of the library and the needs of users and to shape and manage the library collection systematically. With the above conception and definition, we try to make a proper collection development policy and guideline for the Korean university libraries. Here we must define the object of the university. Object of university is to have good curriculum, good courses, research activities on the part of the faculty, enlargement of graduate school, and establishment of various institutes, etc. And in guideline, selector, method of selection, level of selection and arrangement of budget, etc. must be described concretely in its contents. Since collection development policy and guideline of Korean university libraries should concern their situation, we must confer with the result of the survey and analysis on the matter of collection determination. Here the contents include the priority of materials to be collected, method of collecting materials, arrangement of budget, and others. The purpose of this study is to develop a tenative collection development guideline in reference to the Jeonju University Library by means of analyzing the guiding principle, contents of the guideline, and present conditions of the Korean university libraries. The systematic collection development based on the Guideline for Collection Development of the Korean University Library, can offer a satisfactory service to the users of the university community, and also contribute to the development of the university itself as well as the university library.

In flash memory, many previous garbage collection methods only merge blocks statically and do not consider the contents of buffer. These schemes may cause more unnecessary block erase operations and page copy operations. However, since flash memory has the limitation of maximum rate and life cycle to delete each block, an efficient garbage collection method to evenly wear out the flash memory region is needed. This paper proposes a memory compaction scheme based on block-level buffer for flash memory. The proposed scheme not only merges the data blocks and the corresponding log block, but also searches for the block-level buffer to find the corresponding buffer blocks. Consequently, unnecessary potential page copying operations and block erasure operations could be reduced, thereby improving the performance of flash memory and prolonging the lifetime of flash memory.

World leading national science technology information institutes provide scientists with R&D information for increasing national competitiveness. Collection development policy is the guidelines for the science technology information institutes that identify information resources and connect them together to build an information network for supporting R&D. In order to draw main elements of the collection development policy for national level science and technology information institutes, this paper analyzed the policies of National Library of Medicine (NLM), British Library (BL), Canada Institute for Scientific and Technological Information (CISTI), and Korea Institute of Science and Technology Information(KISTI). The results of this study can be used as the guidelines for the science and technology information institutes for establishing collection development policy.

This study was conducted to examine the changes of seed characteristics and germination properties and to determine the most suitable collection time in Ulmus davidiana var. japonica. Seeds were collected six times with the interval of seven days after April 21, 2005 at Jeong-seon. There were differences in seed characteristics and germination properties among seed collection times. The sizes of seed and fruit increased with the collection time, but seed moisture contents decreased with the collection time after increasing until May 5. The 1,000 seeds weight decreased with the collection time after increasing until May 12. Collection time showed high positive correlations (r=0.790, p<0.01) with seed size and negative correlations (r=-0.919, p<0.01) with moisture contents. Percent germination (PG) presented the highest value in seeds collected at May 5, and decreased with the collection time. Mean germination time(MGT), germination speed(GS), and germination performance index(GPI) also showed the highest values in seeds collected at May 5. PG, MGT, and GS had correlations with other seed characteristics except the 1,000 seed weight. The relative growth rate of height and root collar diameter of seedlings presented the highest values in seedling germinated from seed collected at May 5, and seedlings germinated from seeds collected at May 5 and 12 showed the highest values in chlorophyll contents. Consequently it will be possible to product a number of seedlings when the seeds of U. davidiana var. japonica are collected just before drying morphologically.

The social identities and role models of all public libraries originate from the historical and systematic development of analog collections and the high-quality digital contents. Therefore, collection development in public libraries should be treated the most important professional task. Based on these prerequisites, this paper analyzed the classical agendas of analog collection development and paradoxes of digital odyssey, and suggested the future policies and strategies of public library collection development in Korea.
