  • The objective of this study was to investigate the effect of bacterial contamination on elapsed time after preservation on boar semen. Known numbers of Escherichia coli (E. coli) were inoculated to freshly ejaculated semen and sperm parameters such as viability, motility, agglutination, acrosome integrity and hypo-osmotic swelling test were performed during 7 days of liquid preservation. Semen samples were prepared using antibiotic free BTS extender and 4 different levels of E. coli were treated to semen with following concentrations; 3,000, 5,000, 7,000, 10,000 CFU/ml of sperms. Semen samples were preserved at $17^{\circ}C$ for 7 days in semen storage until analyzed. Aliquots were subjected to measure the sperm viability, motility and agglutination using computer assisted sperm analysis (CASA) system, acrosome integrity was performed using chlortetracycline (CTC) staining method and hypo-osmotic swelling test was performed using hypotonic solution from day 1 (day of semen collection) to 7. Detrimental effects on sperm motility and viability were observed 3 days after preservation at the level of 5,000 CFU/ml (p<0.05). Percentage of sperm abnormality was higher (p<0.05) in over 5,000 CFU/ml groups. Sperm agglutination rate was also significantly higher (p<0.05) in groups of 5,000 and 7,000 CFU/ml. The rate of acrosome reacted sperm was higher as preservation time goes in all the samples but the pattern was clearly higher among E. coli contaminated groups (p<0.05). The sperm membrane integrity in terms of hypo-osmotic test, E. coli affects little compared to other sperm parameters. The deleterious effects observed due to the bacterial contamination in semen suggest that importance of hygiene protocol to minimize the bacterial contamination during semen collection and processing.

  • Antimicrobials were one of the great invention of modern era. However, the abuse of antimicrobial both in human and animals has led to a high rate of occurrence of antimicrobial resistant microbes. Disease treatment caused by antimicrobial resistant microbes including superbacteria has emerged as critical issue worldwide. Communication and cooperation among researchers in diverse fields are needed to solve the resistance to antimicrobials. Culture Collection of Antimicrobial Resistant Microbes (CCARM) has taken a leadership role an intermediary among various research fields by providing certified antimicrobial resistant microbes with their information since 1999. CCARM collects antimicrobial resistant microbes from clinical, agricultural animals and products, and environmental fields, and classifies and stores them according to their origins, species and antimicrobial resistance mechanisms. CCARM is performing the roles (collection, deposit, preservation, distribution, service, and consulting) of Biological Resource Center designated by Organisation for Economic Co-operation and Development.

  • Efforts to establish a joint preservation facility for library collection are being discussed by some of regional representative libraries recently. In order for the efficient management and preservation of public library materials and to secure the space necessary for applying new services, there is a high demand for a cooperative shared storage for public libraries. The construction of a cooperative shared storage for public libraries is to minimize the cost of expanding the preservation space for each public library and to provide a pleasant service environment by separating the low-use materials stored in the library. Accordingly, discussions on the construction of a cooperative shared storage for public libraries are being initiated by some representative libraries. This study, in this regard, tried to propose a plan to build a cooperative shared storage for public libraries by a Seoul Metropolitan Library. To this end, it surveyed the estimate size of the collections of public libraries in Seoul and, based on this, proposed the size and strategies for the facility.

  • Oral history has value that steps over the class consciousness and party feeling that records have, and enables a general representation of a human experience. Beside, It must be managed urgently because a collection of oral history has unique and limited. However, domestic related institution do not keep management for release and use of oral history in their mind are only concentrating on accession. Lately, National History Compilation Committee passes through faithful planning procedures and is collecting an oral history collection project. A merit of this project is to have attempted an image photographing. This study is propose that to examines over the all steps to say oral history collection activity to information service and a preservation from collection planning of organization. However, this study is insufficient in the management method how it is connected if does in order to manage the oral history which is collected with a part of a record in a archival institution because this study was only for the purpose of management of oral history. This problem will be studied through a process of checking the real thing of oral history. This study proposed general methodology for oral history management, if institution had a plan of collection and management or had some collection result.

  • 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.

  • All public libraries are collection-based knowledge and cultural service institutions. To this end, a collection development policy is an essential and a strategic menu that every library should establish first. Regional central libraries should establish and apply optimal collection development policies to conduct the legal duties as knowledge and information centers and cooperative preservation facilities of the cities and provinces. Thus, this study analyzed and compared in detail the collection development guidelines (draft) and regulations of regional central libraries in Korea and the collection development policies of metropolitan public libraries abroad. Results showed that the policies of domestic regional central libraries were simply practical guidelines while those in most developed countries were substantial in format and content. All regional central library systems should establish and document collection development policies based on the importance of collection development, future-oriented thinking, and strategic decision. The study also suggested the basic principles and the format for this purpose.
