  • Composting is widely used to transform waste into valuable agricultural organic fertilizer. Anaerobic ammonium-oxidizing (anammox) bacteria play an important role in the global nitrogen cycle, but their role in composting remains poorly understood. In the present study, the community structure, diversity, and abundance of anammox bacteria were analyzed using cloning and sequencing methods by targeting the 16S rRNA gene and the hydrazine oxidase gene (hzo) in samples isolated from compost produced from cow manure and rice straw. A total of 25 operational taxonomic units were classified based on 16S rRNA gene clone libraries, and 14 operational taxonomic units were classified based on hzo gene clone libraries. The phylogenetic tree analysis of the 16S rRNA gene and deduced HZO protein sequences from the corresponding encoding genes indicated that the majority of the obtained clones were related to the known anammox bacteria Candidatus "Brocadia," Candidatus "Kuenenia," and Candidatus "Scalindua." The abundances of anammox bacteria were determined by quantitative PCR, and between $2.13{\times}10^5$ and $1.15{\times}10^6$ 16S rRNA gene copies per gram of compost were found. This study provides the first demonstration of the existence of anammox bacteria with limited diversity in cow manure composting.

  • 본 연구에서는 각 대학의 최근 변화된 강의환경을 고려하여 도서관에서 제공하고 있는 상용 디지털 콘텐츠와 대학의 e-Learning 현황을 분석하고 현재의 환경하에서 요구되어지는 대학도서관 서비스 활성화 방안을 제언하고자 한다. 이를 위하여 e-learning 강의를 이용하고 있는 I 대학의 교수 학생을 대상으로 e-Learning 강의 지원에 미치는 대학도서관에서 제공하는 상용 디지털콘텐츠 서비스 품질에 대한 설문을 실시하였다. 도서관의 상용 디지털콘텐츠 제공 서비스 품절은 디지털도서관 서비스 측정모형으로 사용되어지고 있는 Digital Library Service Quality Index(이하 DL-SQL모형이라 함)을 바탕으로 4개의 차원(정보시스템 품질, 디지털장서 품질, 고객서비스 품질, 고객커뮤니티 품질)과 7개의 구성요인(검색성, 전담조직 및 인터페이스, 접근성, 디지털장서, 고객지원서비스, 개인화서비스, 고객커뮤니티) 등을 일부 수정하여 디지털 콘텐츠관련 서비스 품질을 측정하였다. 측정결과 디지털콘텐츠 관련 도서관서비스에서 "고객서비스"와 "고객커뮤니티" 품질 서비스는 "정보시스템"과 "디지털장서"에 대한 품질 서비스보다 e-Learning 강의 지원과 학습에 더 영향을 주는 것으로 분석 되었다. 이러한 결과는 e-Learning 강의를 개설하는 교수와 수강하는 학생들에게 대학도서관에서 상용 디지털콘텐츠를 구입하여 제공하는 양적 푸싱 서비스 보다는 도서관의 대 이용자 고객맞춤정보 서비스가 e-Learning 강의지원에 더 많은 영향을 끼치는 요인으로 분석됨으로써 향후 대학에서 e-Learning 강의와 연계된 디지털콘텐츠 구축관련 정책수립시 참고해야 할 도서관 서비스 활성화 방안을 제언하고자 한다.

  • The value of the university library to faculty, students, and administrators has long been assumed. In an era of decreasing resources and increasing choices, academic librarians must now find the best ways to measure and demonstrate the value of the library to all of their stakeholders, including faculty members, graduate students, undergraduate students, administrators, and funders. Techniques to assess and measure value can also help library decision makers select the products and services that provide the highest return on investment (ROI) to the university community. It is important to measure and convey the value of the academic library; it is also possible to increase the value of the library to the university by carefully refocusing the academic library's products and services. In this presentation I will discuss methods and results from a recently completed study in eight countries that measured the value and ROI of e-journals to the grants process. The Return on Investment (ROI) of the e-journals collection to grant funding ranged from over 15:1 to just under 1:1 in 9 institutions. In addition, many other qualitative and quantitative measures of value are as important as derived measures like ROI. Building on that research study, I am now leading a team that includes the Association of Research Libraries (ARL) and several university libraries in a project funded by the U.S. Institute of Museum and Library Services. We are collecting data using on the value of a wide range of library services using several methods for measuring the value of what the university library contributes to the institution and its stakeholders.

  • In this study, a model curriculum for the Library and Information Science programs in Junior Colleges is presented by comparing those curricula of the Republic of Korea, the United States of America, England and Japan. In Korea, 80 credits are required for graduate of Junior College and 60 credits of that total credits are for major courses. At Toshokan Danki Daikagu in Japan, 73 credits are opened for the Department of Library Science and 87 credits for the Department of Library and Information Science respectively. In the United States of America, 30 credits for major courses out of 90 total credits are opened at Lansing Community College and 24 credits for major courses out of 60-64 credits at Mesa Community College distinctively. On the basis of the various analyses, the following principles are applied in designning the model curriculum; (1) Possibly 3 credits per subject are assigned, (2) Major credits for graduate are 60-64 credits including possible optional subjects, (3) 20 percents of those 60-64 credits shall be applied for electives, so that 72-78 credits are assigned for major, (4) In order to combine theory and practice, and to select practice areas as required major, the ratio between required and elective must be adjusted, (5) In order to avoid duplication of subject, adequate individuality must be provided, (6) The Information Science areas must be dealt with in Library Science since computer systems are being rapidly adopted in libraries and the education for resources of materials and foreign languages are also important for successful fulfillment of mediator's roles between materials and users. Therefore the following model curriculum is suggested; 31 credits in 11 subjects for required major, 46 credits in 18 subjects for electives in major, total 77 credits for 29 subjects are established, and it includes such areas as material organization, foreign languages, resources of materials, library management, information science, fundamental studies, services and practice.

  • BACKGROUND: Microbes that govern a unique biochemical process of oxidizing ammonia into dinitrogen gas, such as anaerobic ammonium oxidation (anammox) have been reported to play a pivotal role in agricultural soils and in oceanic environments. However, limited information for anammox bacterial abundance and distribution in the terrestrial habitats has been known. METHODS AND RESULTS: Phylogenetic and next-generation sequencing analyses of bacterial 16S rRNA gene were performed to examine potential anammox bacteria in paddy soils. Through clone libraries constructed by using the anammox bacteria-specific primers, some clones showed sequence similarities with Planctomycetes (87% to 99%) and anammox bacteria (94% to 95%). Microbial community analysis for the paddy soils by using Illumina Miseq sequencing of 16S rRNA gene at phylum level was dominated by unclassified Bacteria at 33.2 ± 7.6%, followed by Chloroflexi at 20.4 ± 2.0% and Acidobacteria at 17.0 ± 6.5%. Planctomycetes that anammox bacteria are belonged to was 1.5% (± 0.3) on average from the two paddy soils. CONCLUSION: We suggest evidence of anammox bacteria in the paddy soil. In addition to the relatively well-known microbial processes for nitrogen-cycle, anammox can be a potential contributor on the cycle in terrestrial environments such as paddy soils.

  • The All India Council for Technical Education (AICTE), an apex body of controlling technical education in India, has made mandatory subscription of e-Resources to all its Engineering College Libraries. This policy has directly helped the teaching community, research scholars, and student's paternity, which has benefits for their teaching, research activities, and curriculum, respectively. This study emphasizes the usefulness of e-Resources among the teachers and scholars of engineering colleges in the Bangalore region under Visvesvaraya Technological University (VTU), Belgaum, Karnataka. Survey methodology has been used as the basic research tool for data collection with the help of questionnaires. 866 teaching faculties in VTU were selected randomly on the basis of willingness of users who access the e-Resources for their academic and research activities in the survey. The survey results were tabulated and analyzed with descriptive statistics methods using the SPSS 20 software package. The findings reveal that e-resources are useful for engineering college teachers and scholars for their academic and research activities.

  • The library provides its services to satisfy the user's approach. Naturally, the development of library services may determine by considering the satisfaction of users. It traces users' perceptions regarding subject access highlighting problems in the retrieval of Bengali documents by subject. This study has designed to assess users' attitudes towards the retrievals of Bengali documents in OPAC through subject headings. For a collection of data, a representative sample has drawn from a large and heterogeneous population consisting of users in university libraries of West Bengal using a stratified sampling technique. Subsequently, under each of the universities, users' community was stratified into students, research scholars, and faculty members. Under each stratum, the sample selected on a random basis. The users met personally to collect relevant data, while they came to the library and went on to search OPAC. A structured schedule, prepared for the purpose, was presented before library users and consequently, interviews and interpretations recorded systematically. In this manner, several factors have identified concerning subject searching and retrieval performance for Bengali documents. This study explores the access using subject headings in multilingual information retrieval systems. Moreover, the suitability of subject headings for retrieval of Bengali resources has ascertained from the users' point of view. The findings demand standard principles and rules for the construction of Bengali subject headings to maintain uniformity and consistency.

  • For accurately analysing and forecasting the social networks of China's political, economic and social power elites, it is necessary to develop a database that collates their information. The development of such a database involves three stages: data definition, data collection and data quality maintenance. The present study recommends distinctive solutions in overcoming the challenges that occur in existing comparable databases. We used organizational and event factors to identify the Chinese power elites to be included in the database, and used their memberships, social relations and interactions in combination with flows data collection methodologies to determine the associations between them. The system can be used to determine the optimal relationship path (i.e., the shortest path) to reach a target elite and to identify of the most important power elite in a social network (e.g., degree, closeness and eigenvector centrality) or a community (e.g., a clique or a cluster). We have used three social network analysis tools (i.e., R, UCINET and NetMiner) in order to find the important nodes in the network. We compared the results of centrality rankings of each tool. We found that all three tools are providing slightly different results of centrality. This is because different tools use different algorithms and even within the same tool there are various libraries which provide the same functionality (i.e., ggraph, igraph and sna in R that provide the different function to calculate centrality). As there are chances that the results may not be the same (i.e. centrality rankings indicating the most important nodes can be varied), we recommend a comparison test using different tools to get accurate results.
