  • A combinatorial library of artificial transcription factors (ATFs) was introduced into the bacterial cells that expressed the Akt1-GFP fusion protein. By measuring the level of fluorescence generated by the transformed E. coli cells, we were able to obtain clones in which ATFs increased the solubility of the Akt1. Our results show that ATF library is a useful tool for increasing the solubility of selected recombinant proteins in E. coli.

  • Rapid changes in information technologies are forcing dramatic shifts in how business are conducted in various industry sectors. This pace of change is increasing all around the world. Accordingly, there is a need for the libraries to provide the information services with agility, which emphasizes on the prompt reaction to the changes, which are almost impossible to predict. Especially, the digital libraries higher education institutions require more agility as their main mission is providing a wide range of cutting edge information for the research and education activities. In this study, the notion of 'agility' is examined then the relationship between the digital library's e-service measure evaluation factors and the capability, which is defined as agility, is explored. In addition, the impact of agility in user satisfaction is analyzed. Based on these analyses, the factors to consider in managing digital libraries in higher education institution, are suggested.

  • S. pneumoniae (pneumococcus) gene cloning and library construction in E. coli multicopy plasmid has been hampered, in part, by instability problems. In this study, stability of pneumococcus gene library in cosmid vector and pACYC184 was examined. Pneumococcus library in the cosmid vector pHC79 was extermely unstable that most of the recobinant clones were degenerated rapidly. Only 2 out 849 clones were stable and had appropriate insert size. Pneumococcus library in pACYC184 was also so unstable that the pneumococcal inserg and/or part of the vector were deleted. However, the instability problems seemed to be resolved when transcription teminator plasmid was employed for pneumococcus library construction.

  • The objective of this study is to move the initiative of children's electronic books from portal sites to libraries and to help improving libraries' information services through their systematic study. The present use state of an e-book site for children that is currently serviced by A-academic library was mainly analyzed for the study. The desirable acquisition policies were also suggested for the activation of the juvenile e-book services for libraries.

  • This paper describes qualities of a library classification system that are commonly discussed in the LIS tradition and literature, and explains such a system’s three main functions, namely knowledge mapping, information retrieval, and shelf arrangement. In this vein, the paper states the functional requirements of bibliographic classifications, which broadly are subject collocation and facilitation of browsing the collection. It explains with details the components of a library classification system and their functions. The major components are schedules, notations, and index. It also states their distinguished features, such as generalia class, form divisions, book numbers, and devices for number synthesis which are not required in a knowledge classification. It illustrates with examples from the WebDewey good examples of added features of an online library classification system. It emphasizes that institutional backup and a revision machinery are essential for a classification to survive and remain relevant in the print and e-environment.

  • E-Loaming is a modem main teaching method starting from the concept of remote education. This research is aimed for proposing cyber education library system, and designing a cyber education component that becomes a basis for e-Learning system. Cyber education library is a storage system of cyber lectures that can supply high quality data to the needed developers. Cyber education component consists of 5 categories and those are text, voice, image, animation, and flash. By using this system, the developers can save the necessary time and effort in education development. This system also helps students. The students can access various lecture data on a given subject and select the best fit for them.

  • Information integration of heterogeneous digital parts libraries or electronic pars catalogs is one of issues in B2B procurements. We need to provide an integrated view for multiple information sources. Utilization of ontologies as the metadata descriptions of the information sources can provide an integrated view. However, in order to integrate independently developed ontologies, the mismatches among them should be resolved. In this paper, we propose an ontology of meta-concepts, i.e. meta-ontology. The meta-concepts play the role of vocabulary to describe the parts library ontologies and provide well-established ontological semantics that helps the ontology modelers to consistently identify parts library concepts and systematically structure them. Consequently, the meta-ontology reduces the differences in the way the parts knowledge is interpreted and ensures the mismatches are confined to manageable mis matches, so that a software program can merge automatically. Modeling ontologies of mold and die parts libraries for B2B e-commerce is taken as an example to show how to use the meta-ontology. We also discuss how a parts library mediation system can automatically merge the well-structured parts library ontologies.

  • A marketing platform based on the legal deposit system was designed. It is an e-book distribution platform that systematically binds library networks nationwide by linking with the National Library's deposit system to complete the existing paper that the library should become a publishing platform. The purpose is to bundle e-books into a distribution space and naturally assemble readers to serve as virtual platforms for domestic publishers, authors, bookstores, and platforms running various publishing / subscribing services. The premise is not a sale of e-books, but a rental concept, but the platform is valid regardless. In addition, the platform takes the form of social cooperatives to represent the interests of all members involved in publishing services. The lead-based distribution platform is the most ideal business model to compromise with reality. Conceptually, the service of the publishing content-related industry is a model in which all content is supplied from the lead-bone system, which is a collaborative space, and technically, the central e-book database controls the flow of all content, but the publishing content-related industry takes the form of controlling its flow through virtual.
