  • This study analyzes the authorship of all articles published in four domestic LIS journals over a 20-year period from 2002 to 2021 to examine the current status of scholarly communication through Korean LIS journals and suggest future prospects. To achieve this purpose, the study analyzed the number of co-authors, the proportion of returning authors, the publishing preference index (PPI), the author group change trend, and the researcher attraction index (RAI). The analysis revealed the level of collaborative research in each journal, the degree of formation of related author groups by journal, the inflection point of author group changes, the characteristics of emerging researchers, and the degree of author sharing between journals. Overall, 2015 was found to be an inflection point where the author community of Korean LIS journals changed. The newer generation of researchers showed a slightly different behavior of publishing papers than the older generation, as they mainly conduct collaborative research. These quantitative results could be triangulated with the qualitative interview data of previous studies to further strengthen the development strategy of Korean LIS journals.

  • The compensation system for reproducing or interactively transmitting works in libraries has been introduced in 2003. It has passed more than 7 years since this system has been implemented in July 2004. This study investigated current situation of operation on the compensation system for reproducing or interactively transmitting works in libraries. The survey on the effectiveness of the compensation system was conducted to a group of authors and librarians. First, the difference of the effectiveness of the compensation system between a group of authors and librarians was analyzed. In addition, the difference of the effectiveness of the compensation system according to status variable of author group was analyzed. Also the difference of the effectiveness of the compensation system according to status variable of librarian group was analyzed. Finally, this study pointed out the problems of the compensation system and presented the way to improve the problems.

  • The author co-citation analysis is generally based on the frequency of the first author because most citation databases include only the first author in the bibliographic information. In this sense, the purpose of this study is to provide a better knowledge structure by utilizing the multiple authorship of author co-citation analysis. To achieve the purpose of this study, four different data sets are prepared: (1) counting the first author, (2) counting all the author without limiting the total frequency, (3) counting all the author with limiting the total frequency, and (4) counting adjusted frequencies based on the order of author subscription. The findings of this study show that there are clear differences between the knowledge structure counting all the author and the one counting only the first author. In addition, depending on the different methods, there are subtle changes of cluster members for authors.

  • The succulent herbaceous perennial Sedum sarmentosum commonly grows in the southern part of the Korean Peninsula. It is a species native to China, most likely introduced into Korea due to its edible and medicinal uses. If plants were introduced from a single source, we would expect no or low levels of genetic variation in Korean populations. Alternatively, if plants were introduced from multiple sources, we would expect, in contrast, high levels of genetic diversity. To test which is more likely, we surveyed the degree of allozyme variation in ten populations of this species from southern Korea. We found that S. sarmentosum was monomorphic at all fifteen allozyme loci. However, two congeners (S. polytrichoides and S. kamtschaticum) and two related species (Hylotelephium ussuriense and H. verticillatum) maintain moderate to high levels of genetic diversity ($H_e=0.144$, 0.203, 0.201, and 0.204, respectively). We suggest that southern Korean populations of S. sarmentosum likely descended from a single introduction of a few plants and then became naturalized exclusively via vegetative spreading (as plants in Korea, but also as occurs in other parts of its native and naturalized range, are sterile).

  • In central and southern Korea, the two small insectivorous, terrestrial herbs, Utricularia bifida and U. caerulea, often co-occur at wet locations (or in wetlands). The Korean Peninsula (with central China and northern Japan) constitutes the northern edge of their distribution, as their main range is subtropical and tropical Asia. The Korean populations of both species are very likely of post-glacial origin, given that warm-temperate vegetation was absent from the Korean Peninsula during the Last Glacial Maximum. Two hypotheses of the post-glacial colonization of the peninsula can be formulated; first, if current populations were founded by propagules coming from a single ancestral population (i.e., a single refugium), we would expect low levels of genetic diversity. Alternatively, if contemporary Korean populations originated from multiple sources (multiple refugia), we would expect high levels of genetic variation. To test which is more likely, we surveyed the degree of allozyme variation at 20 loci in ten populations for each of the two species from southern Korea. We found no allozyme variation within each species. However, their aquatic congener U. australis exhibited allozyme polymorphism across Japan (four polymorphic loci at three enzyme systems). We suggest that southern Korean populations of Utricularia bifida and U. caerulea were established by a single introduction event from a genetically depauperate ancestral population.

  • This study, considering the many disputes in today's society centered around copyrights, aimed at analyzing and investigating the scope of application for copyright laws in library, whether where is a reach or not, and also the procedures and cognitive degrees in copying and transmission of copyrights materials. Especially the usage of the digital resources built by major domestic libraries have been looked at, and how they reveal the cognitive degree of copyright laws toward various social stratums have been analyzed. Research subjects in each social stratum were firstly classified, which centered around university library users, authors as well as librarians in each university library public access post, then the difference of understanding toward copyright laws between each of these 3 groups was analyzed, and also at the same time the problems in usage authorization procedures of copyrighted materials in library were analyzed. so that the solutions to such problems can be found.

  • An area comprising Juwangsan National Park and its adjacent mountains (southeastern Korean Peninsula) is a good model system for testing the effects of physical barriers to gene flows in plant populations. We predicted that plant species consisting of isolated populations are genetically more differentiated than those that are rather continuously distributed. Most populations of Sedum polytrichoides occur in four isolated valleys, and we assessed the genetic variability and structures using twelve allozyme loci in ten populations. We also compared the present results to earlier findings pertaining to the two co-occurring herbs Hylotelephium ussuriense (${\equiv}$ Sedum ussuriense) (growing only in the four isolated valleys) and S. kamtschaticum (rather continuously distributed). We found moderate levels of within-population genetic variation in S. polytrichoides ($H_{e}=0.112$). Estimates of among-population divergence in S. polytrichoides were also moderate ($F_{ST}=0.250$) and, as expected, very similar to that of H. ussuriense (0.261) but considerably higher than the variation in S. kamtschaticum (0.165). An analysis of molecular variance (AMOVA) revealed that S. polytrichoides and H. ussuriense had higher percentages of among-valley variation (19% each) than S. kamtschaticum (4%). Most of this variation, as also indicated by the STRUCTURE program, was due to differences in genetic profiles between the two central valleys. We concluded that the genetic differences observed between species (S. kamtschaticum vs. S. polytrichoides and H. ussuriense) are mainly due to differences in their distribution within the study area.

  • 이미 작고한 중국의 자도자 등소평이 복용하여 장소를 누렸다고 하는 동충하초. 1992년 일본 히로시마에서 개최된 국제육상경기대회에서 마준렌이 이끄는 중국의 육상선수들이 신기록을 양산한 비결로 알려지면서 더욱 유명해진 버섯이다(1). 그런데 최근 국내에서 동충하초가 건강식품으로 인지도가 높아지면서 이의 판매를 둘러싸고 이해가 대립된 기관 또는 농민 집단 사이에 마찰이 발생하고, 일반 소비자는 동충하초에 관한 정확한 지식이나 정보가 없는 가운데 상인들의 상술에 농락당할 우려가 있어 자칫 건강에 유익한 새로운 식품소재에 대한 불신이 높아질 수 있는 문제가 발생하고 있다. 따라서 저자는 동충하초에 대한 모든 사람들의 이해를돕고자 그 동안 진행되어 온 상황을 설명하고 (1999년 9월까지), 여기에 내포된 문제점을 지적하였으며, 끝으로 동충하초를 국내 산업에 국한할 문제가 아니라 전세계적으로 동충하초 시장을 석권할 수 있는 발전방향과 규제완화 필요성을 제기하였다. 동충하초에 관한 일반 사항과 효능에 관하여는 저자들이 식품과학과 산업에 투고한 총설에 관련 문헌을 종합하여 요약한 바있다.

  • 수의사의 의사결정 과정에는 모든 의료행위에 내재된 본질적인 특성인 불확실성 (uncertainty)이라는 문제가 필연적으로 개입되는데 특히 진단검사와 관련된 신뢰도와 정확도 측면에서는 더욱 그러하다. 기존의 진단방법에 대체할만한 새로운 검사법이 개발되었을 때 실제로 이를 임상적 진단에 활용하기 위해서는 이 검사의 민감도와 특이도를 추정하는 작업은 필수적이다. 예컨대 표준검사법 (gold standard)이 제시되어 잇을 경우 비교적 간단한 계산으로 추정이 가능하지만 대부분의 질병에서와 같이 표준검사법이 없을 경우에는 상당한 통계적 지식을 요구한다. 또한 소위 표준검사법이라고 하는 검사도 실제로 질병에 이환된 집단과 이환되지 않은 집단을 완벽히 이분해주는 (dichotomize) 능력을 가진 것이라고는 볼 수 없기 때문에 추정과정에 신중을 기해야 한다. 본 원고에서는 다양한 상황에서의 진단검사의 민감도와 특이도를 추정하는 방법에 대하여 기술하며 본 원고에서 설명한 내용과 유사한 자료에 대하여 분석을 원하는 독자는 저자에게 연락을 주면 자세한 분석절차에 대하여 논의가 가능하다.
