  • The most typical roles of libraries in their information societies are public access points to the networks, providing teaching and training, assisting in knowledge resource discovery, and knowledge providers. In order to fulfil these roles, libraries should be a ky element in national and local cultual policies. Effective policy making is the most important responsibility of libraries as well as national and local governments and one of library management tools for running the library. The purpose of this study is, therefore, to review the spectrum of the library and information policies in Korea and suggest some desirable directivities for library policy making.

  • Effect of cross-section libraries on displacements per atom (dpa) was investigated under the spectrum which is calculated in the outer and inner of capsule in the JMTR fuel region. The variation of dpa value of iron was calculated by TENJIN2 code using several cross section libraries (ENDFB-lV, JENDL 3.1 and JENDL 3.2). The dependency of input spectrum on total damage (dpa) is more clearly appeared in case or ENDFB-IV in JENDL 3.2 and JENDL 3.1 libraries. The gas production rate calculated by ENDFB-IV library showed slightly larger value than that by JENDL library, and it responded more sensitively in neutron spectrum.

  • Nowadays, the wide spectrum of changes have been occurred in library world. It is essential for librarians to improve their professionalization standards to convert these changes into the o n.0, pportunity of growth. The device of improvement of professionalization standards is following: 1. Librarians have to receive formal and informal education and learn to advance in knowledge and skill concerning library affairs continually. 2. Self learning has to be transform into learning organization. 3. Education of Librarianship concentrate mainly in practical and technical study by this time but it is indispensable to develop the theory and philosophy of librarianship.

  • Objectives The purpose of this study is to investigate recent clinical studies on effect of acupuncture for Autism Spectrum Disorder in other countries. We have analyzed the studies on effect of acupuncture for Autism Spectrum Disorder within randomized controlled trail (RCT) for 6years (from 2010 to 2015). Methods The search database includes Medline, Embase, Cochrane library and CNKI (China National Knowledge Infrastructure). To narrow the search, the following key search terms were used: 'autism or ASD or Asperger's Syndrome or pervasive developmental disorder, acupuncture'. The search was limited to the publication date from 2010 to 2015. 7 control studies in Medlin, Embase, Cochrane library and 5 control studies in CNKI were selected for analysis. Results and Conclusions 1. The acupuncture and rehabiliation treatment is more effective than only acupuncture treatment. Especially, Retention of needling is helpful. 2. It is necessary to set up standard scale in assessment of ASD patients and serum arginine-vasopressin (AVP) can be substitution. 3. Head acupuncture and tongue acupuncture is effective for ASD.

  • The aim of this study is to develop a protocol for obtaining spectral signals that are robust to varying lighting conditions, which are often found in the Polar regions, for creating a spectral library specific to those regions. Because hyperspectral image (HSI)-derived spectra are collected on the same scale as images, they can be directly associated with image data. However, it is challenging to find precise and robust spectra that can be used for a spectral library from images taken under different lighting conditions. Hence, this study proposes a new radiometric calibration protocol that incorporates radiometric targets with a traditional vicarious calibration approach to solve issues in image-based spectrum measurements. HSIs obtained by the proposed method under different illumination levels are visually uniform and do not include any artifacts such as stripes or random noise. The extracted spectra capture spectral characteristics such as reflectance curve shapes and absorption features better than those that have not been calibrated. The results are also validated quantitatively. The calibrated spectra are shown to be very robust to varying lighting conditions and hence are suitable for a spectral library specific to the Polar regions.

  • NECP-SARAX is a neutronics analysis code system for advanced reactor developed by Nuclear Engineering Computational Physics Laboratory of Xi'an Jiaotong University. In past few years, improvements have been implemented in TULIP code which is the cross-section generation module of NECP-SARAX, including the treatment of resonance interface, considering the self-shielding effect in non-resonance energy range, hyperfine group method and nuclear library with thermal scattering law. Previous studies show that NECP-SARAX has high performance in both fast and thermal spectrum system analysis. The accuracy of TULIP code in fast and thermal spectrum system analysis is demonstrated preliminarily. However, a systematic verification and validation is still necessary. In order to validate the applicability of TULIP code for full energy range, 147 fast spectrum critical experiment benchmarks and 170 thermal spectrum critical experiment benchmarks were selected from ICSBEP and used for analysis. The keff bias between TULIP code and reference value is less than 300 pcm for all fast spectrum benchmarks. And that bias keeps within 200 pcm for thermal spectrum benchmarks with neutron-moderating materials such as polyethylene, beryllium oxide, etc. The numerical results indicate that TULIP code has good performance for the analysis of fast and thermal spectrum system.

  • Since the short-wave infrared spectrum has a significant range of variation depending on the production environment, countries with advanced resource exploration are collecting the spectrum and building a database. Representative organizations include the USGS and CSIRO, and they are currently carrying out a project in China that can synthesize and use a large number of existing data. The USGS library provides a total of 2,457 spectra targeting not only minerals but also various materials that respond to infrared radiation. Among these, there are 1,276 mineral spectra, which are about half of the total. The spectrum title includes information, such as analysis devices (NIC4, BECK, ASDNG, etc.), purity codes (a, b, c, d, u), and measurement methods (AREF, RREF, RTGC, TRAN). Analyzed raw data are provided in ASCII and GIF format. The CSIRO library has a total of 502 spectra, of which the majority, 493, correspond to mineral spectra. The USGS library is a free, publically available resource, while the CSIRO library is bundled with TSG8 or must be purchased separately. Among these, when comparing the eight spectra whose spectral shapes can be analyzed with the spectra of domestic illite, the positions of the absorption peaks are significantly different from those of domestic illite, except for one Japanese illite. Additional research will be needed to determine the causes of such differences, and the domestically relevant databases should be established as well.

  • The essential identity of public library is a local knowledge and information center that guarantees access and use of present generation and descendant. However recently the public library is being called with core space for lifelong learning, hub of cultural activities, information gateway, community center, local public goods, information commons, democracy cradle, the second living room, etc. The spectrum for the identity of the public library in Korea is not only very wide, but also is confused. The researcher who paid attention to such a reality analyzed laws and regulations, local administrative organizations, national and official statistics related public library, and suggested evidences of the identity confusion. Based on this result, researcher proposed the principles and plans to get over the identity confusion of the public library.

  • It is important to select proper ground motions for obtaining accurate results from response history analyses. The purpose of this study is to propose an accurate and efficient method that does not require excessive computation for selecting and scaling ground motions to match target response spectrum mean and variance. The proposed method is conceptually simple and straightforward, and it does not use a simulation algorithm that requires a sophisticated subroutine program. In this method, the desired number of ground motions are sequentially scaled and selected from a ground motion library. The proposed method gives the best selection results using Sum of Square Error and has the smallest value(=0.14). Also, The accuracy and consistency of the proposed method are verified by comparing the selection results of the proposed method with those of existing methods.
