  • With the rapid growth and development of information technology and the Internet, the amount of information published in electronic formats such as video, audio, digitalized text, etc. and the number of users accessing information online to satisfy their information needs are growing at a tremendous rate. This study analyzes standardized components to construct ERMS and proposes a model of ERMS based on the result of the analysis. The main functions of ERMS in university libraries are: 1) ERMS can manage and control access information to various electronic resources, metadata, holdings, user resources. Also, ERMS can be compatible with an existing library system such as IR(Information Retrieval) system, linking system, or proxy system. 2) ERMS should completely be compatible with acquisition and cataloging systems for effective management and control of integrated information organization and library budget. 3) ERMS should systematically and effectively manage license information on electronic resources. 4) ERMS should provide ideal and effective environment for use and access control of electronic resources in a library and integrated tool to manage and control all of electronic resources. Additionally, this study points out the need to organize committee groups to establish standardized rules and collaborative management of electronic resources among university libraries like DLF ERMI and redesign organizations in a library and a librarian's job description.

  • Many universities are offering some of their offline courses for anyone to learn free online as an MOOC format. University libraries In response to changing university conditions, foreign university libraries are struggling to redefine their roles and provide new services. This study aimed to find the trends and models to support MOOCs in foreign libraries and Library and information science domain by conducting a systematic review of studies on foreign library and information journals which have been published from 2012 to 2015. A total of 34 out of 348 studies were included in the final analysis. This study also aimed to present the limits and the future models of MOOC support direction. The relevant articles could be identified, two criteria: 24 MOOCs studies relating to Libraries and 10 MOOCs studies related to LIS. The selected articles were summarized and analyzed yearly. The study identifies elements of library MOOC support models in 5 areas including MOOC design (copyright clearance and consulting, content licensing, open content), production support (course production, video editing, librarian MOOC production), management support (instructional design and content creation, students support), evaluation (MOOC data collection, analysis), reuse (MOOC metadata management, archive structure). Based on these findings, this study suggested the models of library MOOC support and set the theoretical fundamentals.

  • Changes of component(amino acid, free sugar, fatty acid and mineral) and antioxidant effect by pickling of soybeans we.e investigated. Soybean cultivars, Daewon, Pungsannamul, Hwaeum(yellow bean), Ilpum Black and Zynuni(black bean) were soaked in persimmon vinegar for 10 days at $20^{\circ}C$. The major amino acids of raw soybeans were glutamic acid, aspartic acid, lysine and leucine. The content of total amino acid decreased by pickling. The major free sugar of raw soybeans were glucose, fructose and sucrose. Sucrose decreased and glucose and fructose increased by pickling. Maltose was found only in pickled Daewon and Ilpum Black. Linoleic and linolenic acid content of raw soybeans were $49.3%{\sim}57.1%\;and\;7.8{\sim}8.9%$, and the fatty acid contents did not change by pickling. The major mineral elements were K, P and Mg, and their compositions except for Na did not change by pickling. Total phenolic compound, vitamin $B_1$ and C content increased during pickling. The antioxidant effects, electron donating abilities, nitrite-scavenging abilities increased by pickling.

  • The study aims to analyze Thomas Young's problem solving processes of analogical reasoning during the formation of the interference theory of light, and to draw its implications for secondary science education, particularly for enhancing creativity in science. The research method employed in the study was literature review of the papers which Young himself had written about sound wave and property of light. His thinking processes and specific features in his thought that were obtained through analysis of his papers about light are as follows: Young reconsidered Newton's experiments and observations, and reinterpreted Newton's results in the new viewpoints. Through this analysis, Young discovered that Newton's interpretation about his own experiments and observations was faulty in a certain point of view and new interpretation is necessary. Based on the data, it is hypothesized that colors observed on thin plates and colors appeared repeatedly on Newton's ring are appeared because of the effect of light interference. Young used analogical reasoning during the process of inference of similarity between sound and light. And he formulated an hypothesis on the interference of light through using abductive reasoning from interference of water wave, and proved the hypothesis by constructing an creative experimental device, which is called a critical experiment. It is implicated that the analogical reasoning and experimental devices for explaining the light interference which Young created and used can be utilized for school science education enhancing creativity in science.

  • Light and transmission electron microscopy of Batillus cornutus hemocytes revealed differences that the morphological distinctions between blast-like cell, granulocytes and hyalinocytes. Base on the morphological characteristics of the cells, we identified the eight types of hemocytes and present a categorization of the hyalinocytes into six sub-categories. The hemocytes of B. cornutus were observed basophilic cell under the light microscopy. Blast-like cells had a spherical profile with a central nucleus filling almost the whole cell. Granulocytes were characterized by presenting variable numbers of granules. This cell had spherical shape with diameter 7 ${\mu}m$ and smooth endoplasmic reticula, granules, mitochondria, glycogen granules in the cytoplasm. Hyalinocytes were the most abundant cell type. Especially, hyalinocyte VI had iirregular an amoebal shape and observed autophagosome and heterophagosome in the cytoplasm. From these results, it is concluded that there are eight types of cells in the hemolymph of B. cornutus. Further studies are now needed to identify the role of these hemocytes in the enzymological and immunological response.

  • As the technologies of semiconductor and multimedia communication have been improved. the high-quality video and the multi-channel audio have been highlighted. MPEG Audio Layer 3 decoder has been implemented as a Processor using a standard. Since the synthesis filter of MPEG-1 Audio Layer 3 decoder requires the most outstanding operation in the entire decoder. the synthesis filter that can reduce the amount of operation is needed for the design of the high-speed processor. Therefore, in this paper, the synthesis filter. the most important part of MPEG Audio, is materialized in FPGA using the method of DAULT (distributed arithemetic look-up table). For the design of high-speed synthesis filter, the DAULT method is used instead of a multiplier and a Pipeline structure is used. The Performance improvement by 30% is obtained by additionally making the result of multiplication of data with cosine function into the table. All hardware design of this Paper are described using VHDL (VHIC Hardware Description Language) Active-HDL 6.1 of ALDEC is used for VHDL simulation and Synplify Pro 7.2V is used for Model-sim and synthesis. The corresponding library is materialized by XC4013E and XC4020EX. XC4052XL of XILINX and XACT M1.4 is used for P&R tool. The materialized processor operates from 20MHz to 70MHz.

  • Eu doped YRO$_4$ (R=As, Nb, P, V) red phosphors were prepared by the combinatorial chemistry method. The quaternary material library of tetrahedron-type composition array was designed to investigate the luminescence of the host material under UV and VUV excitations (254, 147 nm). The photoluminescent characteristics of the samples were comparable to the commercially available red phosphors such as (Y, Gd)BO$_3$: $Eu^{3+}$ and Y$_2$O$_3$: In view of the luminescence yield, V rich region was found to be optimum under UV excitation. But the results under VUV excitation were different from those of UV excitation, the samples of the composition containing a large amount of P shows the highest luminescence. Especially, higher luminescence was obtained in $Y_{0.9}$(A$S_{0.06}$N$B_{0.06}P_{0.83}V_{0.06}$) O$_4$: $Eu_{0.1}$ phosphors than commercial (Y, Gd)BO$_3$red phosphors under 147 nm excitation.

  • Currently, the method of user-follwoing in intelligent cooperative robots usually based in vision system and using Lidar is common and have excellent performance. But in the closed space of Corona 19, which spread worldwide in 2020, robots for cooperation with medical staff were insignificant. This is because Medical staff are all wearing protective clothing to prevent virus infection, which is not easy to apply with existing research techniques. Therefore, in order to solve these problems in this paper, the ultrasonic sensor is separated from the transmitting and receiving parts, and based on this, this paper propose that estimating the user's position and can actively follow and cooperate with people. However, the ultrasonic sensors were partially applied by improving the Median filter in order to reduce the error caused by the short circuit in communication between hard reflection and the number of light reflections, and the operation technology was improved by applying the curvature trajectory for smooth operation in a small area. Median filter reduced the error of degree and distance by 70%, vehicle running stability was verified through the training course such as 'S' and '8' in the result.
