With the advent of electronic publications, the cataloger is no longer providing access to just the library's archives. This paper intends to describe the concepts, types and characteristics of electronic information resources, and to review some projects and issues related to the cataloging of remote electronic resources, especially field 856(electronic location and access) in the USMARC. In an electronic world, organization occurs in whatever way is needed to provide quick and thorough access to information objects, regardless of physical constraint. Given the issues, it is obvious that cataloging in the electronic world can no longer be done the same as it has been in the past. We must ask ourselves what we want to see in the future of cataloging and what the acceptable norm of organization for the electronic world is if not cataloging as usual.

In the print information world, purchasing books in a library includes rights both to own them and to access to them. In an information world, access to electronic resources often takes place within the confines of a license that defines appropriate use over a specified period of time. Most of these electronic resources are governed by license agreements. This paper describes recent licensing issues which remain unresolved in the area of business model, archive, and fair use and also investigates formal evaluation criteria for developing electronic resources in a library. This study provides licensing principles and considerations for managing the licensing of electronic resources.

In order to recover valuable metals from fine-grained electronic waste, bioleaching of Cu, Zn, Al, Co, Ni, Sn and Pb were carried out using Aspergillus niger as a leaching microorganism in a shaking flask. Aspergillus niger was able to grow in tile presence of electronic scrap. The formation of organic acids(citric and oxalic acid) from Aspergillus niger caused the mobilization of metals from waste electronic scrap. In a preliminary study, in order to obtain the data on the leaching of Cu, Zn, Al, Co and Ni, the metal leaching behaviours were accomplished using Organic acid(Citric acid and Oxalic acid) instead of Aspergillus niger. At the electronic scrap concentration of 50g/L, Aspergillus niger were able to leach more than 95% of the available Cu, Co. But Al, Zn, Pband Sn were able to leach about 15-35%. Ni and Fe were detected in the leachate less than 10%.

Most university libraries in Korea have expanded the subscription of high-quality electronic resources in their amount and category, which are directly available to academic and research users via the web. Despite more than a decade's history, however, a lack of statistics made it difficult to get the overall pictures of electronic resources subscription status in Korea. The purpose of this study is to provide the analysis on nationwide statistics survey of how much money are spent on electronic resources, what kinds of subject resources are mainly subscribed, and how they are used and required by academic users, etc. Some comparisons are made with several factors that have effect on collection development of university libraries. This study will contribute to the future selection and subscription of electronic resources.

The purpose of this study is to investigate the use of the electronic information resources of humanities scholars in Korea and propose the planning of academic library and information services to serve their needs. To collect data, a postal survey was conducted during the period of November 2007 through January 2008. Out of 799 humanities scholars sampled from 25 universities, 132 responded with a completion rate of 16%. The major findings of this study are as follows: Firstly, the majority of humanities scholars distribute their time equally between research and education, and conduct independent research. Secondly, they use, to a certain degree, electronic information resources largely in text format, and depend upon the electronic collection of their academic libraries. Thirdly, with the exception of a couple of sources of electronic journal resources, the electronic resources that these humanities scholars regularly use vary so widely that none could be considered to be a common resource. Fourthly, they value the convenience of accessing and using electronic resources, but worry about the quality and scope of the contents. It is suggested that academic libraries (1) become the gateway for the electronic information that is available both inside and outside the library, (2) provide integrated search feature for and a 'single sign on' access to electronic resources, and (3) plan customized user education for specific subject fields in the humanities.

With the rapid and broad changes of information media and information environment the traditional libraries have been evolving into the digital libraries. An analysis for the Planning and realization of the electronic resource management system was carried out to establish the various electronic resources in the digital library, the first in Korea. The study targeted from electronic journals, web-based databases, e-books, and to open access resources. The focus of the analysis lies in the Providing practical integrated electronic resource management for digital librarian based on the framework of effective Electronic Resource Management Initiative(ERMI) of Digital Library Federation(DLF) with network and electronic resource description. The analyses included life-cycle, subscription models, coverages. types of information provider for electronic resources. and system organization for implementation of electronic resource management system.

A developed neutron activation analysis(NAA) and gamma-spectrometry were applied to improve the analytical sensitivity and precision of impurities in electronic-circuit raw materials. It is well known that soft errors in high precision electronic circuits can be induced by alpha particles emitted from naturally occurring radioactive impurities such as U and Th. As electronic circuits have recently become smaller in dimension and higher in density, these alpha-particle emitting radioactive impurities must be strictly controlled. Therefore, new NAA methods have been established using a HTS(Hydraulic Transfer System) irradiation facility and a background reduction method. For eliminating or stabilizing fluctuated background caused by Rn-222 and its progeny nuclides in air, a nitrogen purging system is used. Using the developed NAA and gamma-spectrometry, ultra trace amounts of U(0.1ng/g) and Th(0.01ng/g) in an alumina ball and high purity silica used for an epoxy molding compound (EMC) could be determined.

University books are an important information resource. University book resources can be shared not only in the traditional paper form, but also electronic form under the background of the Internet. In order to better manage the sharing of electronic book resources in universities, this study put forward three resource sharing strategies: centralized sharing strategy, distributed sharing strategy, and centralized-distributed sharing strategy by analyzing the combined development of books and the Internet as well as the significance and development of book resource sharing. The centralized sharing strategy, however simple, was difficult to handle large traffic; while the resource nodes were independent and self-consistent, the distributed sharing strategy was not easy to find and had a high repetition rate. Combining the advantages of both strategies, the centralized-distributed sharing strategy was more suitable for the heterogeneous form of university book sharing. Finally, a teaching resources sharing platform for university libraries was designed based on the strategy of centralized and distributed sharing, and three interfaces including platform login, resource search, and resource release were displayed. The results of the simulated comparison experiment showed that centralized and distributed sharing strategies had limitations in resource searching and had low efficiencies; the efficiency of the centralized strategy reduced with an increase in search subjects; however, the centralized-distributed sharing strategy was able to search more resources efficiently and main stability.
