This research was initiated on the basis that public libraries should serve its role as a supplier of intellectual informations to all users and the National Library of Korea should play a role as chief supporter of collection preservation in individual libraries. Situated in such context, this study attempted to investigate several aspects of the present conditions of Korea public libraries, including the current technical ability and technicians available for materials preservation and restoration, current policies for preservation and provisions for disasters, and opinions on establishment of national library preservation and restoration center. Data was drawn from a survey with 208 public libraries in the country. As a conclusion, this study discusses such as 1) securing collection management policies for material preservations and restorations at the level of individual libraries 2) building tripartite system for efficient and methodical material preservations and restorations including public libraries, regional central libraries and the National Library of Korea.

Liquid nitrogen storage is the most effective way to preserve many fungi including what cannot be lyophilized. The use of polypropylene straws instead of cryotubes has many advantages in economy, safety, convenience, and space-saving. We, Korean Agricultural Culture Collection (KACC), established the fungal preservation methods in liquid nitrogen using polypropylene drinking straws and introduced the methods in detail.

Bacillus velezensis strain WRN014 was isolated from banana fields in Hainan, China. Bacillus velezensis is an important member of the plant growth-promoting rhizobacteria (PGPR) which can enhance plant growth and control soil-borne disease. The complete genome of Bacillus velezensis WRN014 was sequenced by combining Illumina Hiseq 2500 system and Pacific Biosciences SMRT high-throughput sequencing technologies. Then, the genome of Bacillus velezensis WRN014, together with 45 other completed genome sequences of the Bacillus velezensis strains, were comparatively studied. The genome of Bacillus velezensis WRN014 was 4,063,541bp in length and contained 4,062 coding sequences, 9 genomic islands and 13 gene clusters. The results of comparative genomic analysis provide evidence that (i) The 46 Bacillus velezensis strains formed 2 obviously closely related clades in phylogenetic trees. (ii) The pangenome in this study is open and is increasing with the addition of new sequenced genomes. (iii) Analysis of single nucleotide polymorphisms (SNPs) revealed local diversification of the 46 Bacillus velezensis genomes. Surprisingly, SNPs were not evenly distributed throughout the whole genome. (iv) Analysis of gene clusters revealed that rich gene clusters spread over Bacillus velezensis strains and some gene clusters are conserved in different strains. This study reveals that the strain WRN014 and other Bacillus velezensis strains have potential to be used as PGPR and biopesticide.

We conducted a survey in collaboration with the Chungcheongbuk-do Office of Education to assess the current status of collections in public libraries affiliated with the Office of Education. The objective of this survey was to identify the current challenges and determine when these libraries are expected to reach a state of collection saturation. Libraries under the jurisdiction of the Chungcheongbuk-do Office of Education are currently facing significant challenges due to severe collection saturation. This underscores the pressing need for the systematic expansion and operation of a collaborative preservation library for a swift response. In the future, it appears that the focus during the transfer process will primarily be on transferring collection-oriented materials. Given the difficulty in providing preservation facilities at individual library levels, materials with preservation value, such as rare books and specialized resources, will need to be transferred to the collaborative preservation library. Additionally, the development of policies and regulations related to material preservation seems necessary. Furthermore, when transferring materials to the collaborative preservation library in the future, it appears that criteria for material transfer will be needed, particularly concerning issues such as a decrease in usage rates for less frequently accessed materials. Subsequent research should consider conducting a survey on the collection saturation status of public libraries under local governments in order to assess the overall need for collection expansion in all public libraries within Chungcheongbuk-do.

Effects of various preservation periods and subcultures on fruiting body formation of Cordyceps militaris were investigated using EFCC C-10995 single ascospore strains. Fruiting body formation by original strains was profuse when preserved at $4^{\circ}C$ for $5{\sim}6$ months. Fruiting from subcultures was stable till second to sixth subcultures, after which it decreased sharply. The more the colony color of subcultures changed, the less the fruiting bodies formed. Liquid inoculum preparation of single ascospore strains in the same or separate broths did not affect fruiting body formation. Similarly, two strains C-10995-3 and C-10995-6 in different numbers during liquid inoculum preparation produced similar fruiting bodies.

Introduces and analyzes basic library collection management issues regarding electronic journals, including selection, budgeting, policy making, collection evaluation, and preservation/archiving. Argues that staffing and budgeting for electronic journals can be organized on subject-based or format-based approaches, or some combination of both. Electronic journals are selected through the same three-stage process used for print journals : identification, evaluation, and selection. Most of the traditional criteria for print journals are also applicable to electronic journals, but additional criteria are superimposed on them. The cancellation and weeding of electronic journals have not been addressed ;by ;the profession, but will assume more significance in the future. There is a need for new client-centered evaluation methodologies that focus on availability and accessibility rather than ownership.

In this study, we analyzed the current situation of court libraries and aimed to propose a future-oriented strategy for preserving and managing their collections. Based on literature and status analysis, the study presents the future preservation strategy of court library collections in three main categories: First, securing space for the long-term preservation of court library collections; second, establishing a system for collecting and preserving court library collections; and third, performing digital archiving for the permanent preservation and utilization of court records, valuable legal volumes, administrative materials, and other judiciary-specific resources. Through this, court libraries, including those in various courts, should resolve the issue of insufficient collection storage space, preserve holdings systematically and efficiently, and activate library use.

A total of 7039 strains of filamentous fungi are preserved in Korean Agricultural Culture Collection (KACC). The 4065 strains (58%) of them, which produce many spores in cultivation on proper media, are preserved with freeze-drying method. They are also preserved with liquid nitrogen and deep-freezer storage in order to minimize loss by death. Aspergillus, Penicillium, Lichtheimia, Mucor, Rhizopus, etc. which are common in surrounding environments, are included in this category. The others which do not produce spores, or produce few spores in vitro, are preserved with liquid nitrogen, deep-freezer and mineral oil storage. Phytophthora, Pythium, Cercospora, Septoria, Rhizoctonia, etc. are included in this category. The authors also introduced various fungal preservation methods and provided detailed preservation procedures that are used in KACC.
