  • 정보자원의 지속적 증가와 다양화 그리고 네트워크를 이용한 정보 접근과 활용 등 정보환경의 변화로 도서관 장서개발 정책은 더욱 정교하게 변화되어야 하는 상황에 있다. 국립중앙도서관은 이러한 시대적 조류를 반영하고 그 역할과 사명을 다하기 위하여 보다 체계적이고 합리적인 국가장서개발정책을 수립해야 할 것이다. 본 연구에서는 우리나라와 주요 선진국의 국립도서관 장서개발정책을 조사하고 이를 기반으로 우리나라 국가장서 구축을 위한 기본모형을 도출하였다. 기본모형은 크게 하이브리드장서 구축, 협동연계장서 구축, 장서 평가, 그리고 장서개발정책 성문화 등 네 가지의 서브모형으로 구성되어 있다. 모형별 세부 내용과 추진방안이 제시되었다.

  • The objective of this study was to determine the effect of administration of Prostaglandin $F_2{\alpha}$ ($PGF_2{\alpha}$) on semen collection training and semen characteristics in sexually inexperienced boars. Boars were moved individually to a semen collection pen and were trained to mount dummy sow. During the first and second semen collection secessions, 4 out of 17 boars and 4 out of remaining 13 boars allowed collection of semen. The 9 boars that failed semen collection from first 2 attempts received immediately 15 mg of $PGF_2{\alpha}$ i.m. (intramuscular injection) upon entering the collection pen for semen collection resulted in successful semen collection from all 9 boars. Total numbers of spermatozoa were higher in $PGF_2{\alpha}$ treated boars but there was no significant difference in % motility kinematics characteristics between control and $PGF_2{\alpha}$ treated groups during 72 hr period. Overall, administration of $PGF_2{\alpha}$ in sexually inexperienced boars increased the sex drive and facilitated the mounting activity to the dummy sow for semen collection.

  • The soybean [Glycine max (L.) Merr.] is one of the most important crop resources worldwide as food and forage. It is also important and valuable that to hold crop resources to have high genetic diversities. Recently, a core collection has been constructed in many plants to preserve the genetic resources of various plants. A core collection is small population to represent the genetic diversity of the total collection, and is of strategic importance as they allow the use of a small part of a germplasm collection that is representative of the total collection. Here, we developed the core collection consisting of 816 accessions by using approximately 180,000 (180K) single nucleotide polymorphisms (SNPs) developed in previous study. In addition, we performed genetic diversity and population structure analysis to construct the core collection from entire 4,392 collections. there were excluded sample call rates less than 93% and duplicated samples more than 99.9% according to genotype analysis using 180K SNPs from entire collections. Furthermore, we were also excluded natural hybrid resources which Glycine max and Glycine soja are mixed in half through population structure analysis. As a result, we are constructed the core collection of genetic diversity that reflects 99% of the entire collections, including 430 cultivated soybeans (Glycine max) and 386 wild soybeans (Glycine soja). The core collection developed in this study should be to provide useful materials for both soybean breeding programs and genome-wide association studies.

  • 지식기반사회와 디지털환경의 도래로 도서관 특히 국가도서관이 변화하고 있으며, 도서관의 핵심인 장서개발에 대한 새로운 개념, 과정 및 도구가 변화하고 있다. 이 논문의 목적은 국가도서관에서 지속가능한 자원의 수집과 보존을 보장하기 위해 하이브리드 자원 개발의 방향을 제시하고자 한다. 따라서 이 논문은 국가도서관과 장서개발의 변화를 살펴보고, 표준에서 제시된 성과지표, 정의, 목적 및 사명을 통한 국가도서관의 포지셔닝에 의거하여 국가 장서의 범위를 고찰하였다. 또한 도서관 관련법을 통해 디지털자원의 납본방법을 제시하고, 국가도서관에서 하이브리드 장서개발체계와 함께 온라인 디지털 자원의 아카이빙 방법을 고찰하였다.

  • The Korean National Agrobiodiversity Center holds the more than 1300 accessions of proso millet, but a large portion of accessions are landrace of Korea that has very similar traits. To comprehend the maximum genetic diversity of this crop, a core collection with minimum number of accessions will facilitate easy access to genetic material. Here we assessed the genetic diversity and population structure in a germplasm collection of 830 accessions by employing EST-SSR markers and morphological traits. A total of 107 alleles were detected with an average allele number of 4.9 per locus among the 830 accessions based on 37 EST-SSR markers. The number of alleles per locus ranged from 2 to 7. Polymorphism information content and expected heterozygosity ranged from 0.06 to 0.68 (mean = 0.21) and 0.06 to 0.73 (mean = 0.23), respectively. The germplasm collection was separated into two groups based on population structure analysis, whereas principal coordinate analysis (PCoA) could not cluster accessions according to their geographic origin. Subsequently, a preliminarily developed core collection with a total of 141 accessions (17%) was selected from the whole set of germplasm by combining allelic variations of EST-SSR markers and eight different phenotypic traits. The core collection optimally represented the whole germplasm collection and displayed a similar level of PCoA value and genetic variation from the initial collection. The results obtained here provide a primary resource for further genetic analysis and establish a reference for further development of appropriate genetic breeding strategies.

  • Cordyceps militaris specimens were continuously collected by Entomopathogenic Fungal Culture Collection (EFCC), Kangwon National University from different mountains, national parks and recreation parks of Korea from 1986 to 2002, mainly from late May to October of each year. Dry specimens of C. militaris along with their isolates have been preserved in EFCC. Fruiting of C. militaris was induced from single ascospore isolates as well as their combinations in brown rice medium. Fruiting experiments showed that combinations of single ascospore isolates produced fertile fruiting bodies, but single isolates could not produce any fruiting bodies. It was shown that two isolates of the opposite mating types were required to produce fertile stromata. However, combinations of the same mating type isolates produced no fruiting body, showing that C. militaris is a bipolar, heterothallic fungus.

  • 국가도서관은 한 국가의 지식문화유산인 국가장서를 집중적으로 개발 보존하고 제공해야 할 책무를 지니고 있으며, 이러한 국가적 책무를 수행하는 기관으로서의 정체성과 위상을 유지하기 위해 국가장서의 개발 관리를 위한 장서개발정책의 수립이 필수적이다. 이를 근거로 이 연구는 국립중앙도서관 장서개발정책의 기본적 원칙과 지침을 설정하고 유형별, 매체별, 주제별 장서개발을 위한 지침을 요체로 하는 최적의 정책모형을 제안하였다. 그 기본방향은 모든 관종을 대표하는 국립도서관, 국내의 모든 정보자료를 제출받는 납본도서관, 한국인의 정신세계와 지식문화를 축적 전수하는 보존도서관, 인터넷 정보유통을 선도하는 게이트웨이로서의 정체성과 역할로 설정하였으며, 주요 국가도서관의 장서개발정책을 분석하여 구성체계, 구조적 및 내용적 특징을 도출하고 이를 근거로 선택적으로 벤치마킹하되 변용하였다. 결과로 서문, 장서개발의 대상, 주체, 방법, 장서개발의 우선순위와 기본원칙, 장서개발 기본지침, 주제별 집서수준 지침, 보존관리 및 제적 폐기 지침, 협동장서개발 전략, 장서개발정책(CDP)의 관리주체 및 개정주기로 구성된 국가도서관 장서개발정책 모형을 제시하였다.
