This article aims at bibliographical analysis of the and historical research of Buddhism in the period of king ChungYeul. The analysis is made in the respects of: 1) physical form 2) historical aspect of the Zen Buddhism in the latter period of Koryo Dynasty 3) related persons who corresponded with Mongsan First, this books is consist of 56 records about tripitaka, biography of Mongsan, poets of Zen Buddhism, and abstracts of Buddhist books. Secondly, the new trends of Buddhism in the 13th century was influenced by Mongsan Son(contemplate school, zen). He was corresponded with some political persons and the elite class of Koryo Buddhism. Because of these meetings, LimJae Son were adopted main stream of zen Buddism in Koryo Dynasty by Mongsan and his accompanies. Thirdly, these political groups want to meet Mongsan and his teaching about zen Buddism, but he suggest three questions to the gourp instead of meeting. And he explained 10 kinds of methods to study zen Buddism comparing visited ten persons with ten pinetrees. In the Koryo Dynasty, Buddism was very inportant in history of throughts and social functions. But there had been little research on Mongsan who afford theoretical base on zen Buddism in Chosun Dynasty. On the point of the relation to Koryo and Yuan dynasty in zen Buddism. The is a new and important records that afford some solutions of religious branch and trends in early periods of Chosun Dynasty.

Electrocardiogram (ECG) classification has become an essential task of modern day wearable devices, and can be used to detect cardiovascular diseases. State-of-the-art Artificial Intelligence (AI)-based ECG classifiers have been designed using various artificial neural networks (ANNs). Despite their high accuracy, ANNs require significant computational resources and power. Herein, three different ANNs have been compared: multilayer perceptron (MLP), convolutional neural network (CNN), and spiking neural network (SNN) only for the ECG classification. The ANN model has been developed in Python and Theano, trained on a central processing unit (CPU) platform, and deployed on a PYNQ-Z2 FPGA board to validate the model using a Jupyter notebook. Meanwhile, the hardware accelerator is designed with Overlay, which is a hardware library on PYNQ. For classification, the MIT-BIH dataset obtained from the Physionet library is used. The resulting ANN system can accurately classify four ECG types: normal, atrial premature contraction, left bundle branch block, and premature ventricular contraction. The performance of the ECG classifier models is evaluated based on accuracy and power. Among the three AI algorithms, the SNN requires the lowest power consumption of 0.226 W on-chip, followed by MLP (1.677 W), and CNN (2.266 W). However, the highest accuracy is achieved by the CNN (95%), followed by MLP (76%) and SNN (90%).

Today's public libraries in communities are on the processes of changes to integrate information and communication technology into traditional library system in order to support current users' demands for the new digital era. The purpose of this study is to examine the changing characters on space design and space uses of community based public libraries by conducting case studies of three branch libraries which were built after 2004 in Ann Arbor, Michigan in the United States. As the conclusion of this research, the findings of the case studies are utilized as basic data for planning and design guidelines for public libraries as community resources. The study summarizes the characteristics of space design and space uses in public libraries as follow; first, the floor plans of small-scale public libraries are open visually as well as spatially. The space organization of the libraries is arranged by potential noise levels, as placing noisy spaces near the entrance halls and quiet spaces at the back. Main book shelves are located in the middle of the library buildings, while seats are arranged along the window sides. By placing various kinds of furniture in open reading areas, library users can select different types of seats and tables for their comforts. Second. the survey of observation also finds that a large number of users often use library computers and personal computers to connect the internet at the libraries. These personal computer users who are new user group in community based libraries preferred to sit in casual study areas and individual tables with one or two seats only. Third, the libraries, in addition, develop and provide various programs and events for people in communities. Especially, the programs for children, the elderly and new comers from the abroad are well prepared, thus provide opportunities for them to visit the libraries in regular bases. The survey finds that family entertainment and leisure activities are the important parts of the program as well as renting music CD and movie DVD are also important reasons for people to come. Thus, the libraries prepare high quality children's space and CD shelves near the entrance hall.

As the digital information infrastructure is established for the public library system in the contemporary age, expectations and demands surrounding the public library system are growing rapidly as the place of exchange and enjoyment of information and culture, and as the place of life-long learning. In addition, a new kind of information & culture services are needed to meet the demands of contemporary men and women, who are exploring information as the information environment undergoes rapid changes - from increase in the volume of digital publications, to increase in the usefulness of online information resources, to strides made in the media industry. The public library will continue to play its role and function by providing to all users all available information, whether it's available online or offline, whether it's in a physical format or in a digital format. As such, design and management of a space appropriate as a new information environment are needed. It is deemed that an information infrastructure for Daegu that can improve the quality of life in the region and can increase user accessibility to information in this information age is needed, as well as reorganization of the pertinent environment. Therefore more public libraries have to be built in Daegu as a necessity, and it is urgently needed that the information services be expanded through an organic linkage between local libraries such as between the central library and the branch libraries. This paper aims to provide basic data for building of public libraries in Daegu. To establish an information infrastructure for Daegu, a direction is given for the establishment of a local network of public libraries and ways for improvement are explored. This paper is significant in that, first, it helps in the planning of a local network of public libraries, which plays a crucial role in improving accessibility to information as well as the level of their use; and second, it helps in setting up guidelines for spatial configuration of the user space. As for the method, quantitative review of the information environment is to be done by analyzing the present situation of the public library network in Daegu from the perspectives of region, facility, and space, in order to present a method of user-centered spatial configuration that meets the changes in social roles and forms of information in the contemporary society.

Indexes has not devcloped as an independent branch in library science from the beginning, but it has gradually evolved in a clo~eas sociation with catalog and under the direct influence of the development of publishing pro cesses and of the rapid social changes. Historically, index in the West can be traced back to eariler concordance. On the other hand, index in the Bast does not show a continuous development. It started with book catnlog, but other types of indexing were later 'adopted from the West. Indexing in the West and in the East can be summarized as follows: 1) In the West, Taylor considers Gesner's Pandectae was the first index but the Concordance of the Bible in 1247 was the first true index. Indexing method was first established later in 1545 in Gesner's Partitiones which appeared in three volumes. Classified index appeared after Partitions, but alphabetically ordered index was not developed until th eseventeenth century. The pxiodical index of La France S~auante in 1683 proved -its value, and Poole's An Alphabetical Index in the nineteenth century became the turning point in the development of indexing. After Poole's Index appeared periodical index and book catalog gradually began to be treated separately, and subject index and cross reference were incorporated into indexing. Also dictionary arrangement of the indexed items was adopted in the second half of the nincteenth, century after Charles A. Cutter developed his theory of rules for dictionary catalog and systematic studies of indexing were carried out by many scholars. In the twentieth century, index was mainly developed in the United States of America, especially by Wilson publishing Company. The general trend is to move away from the gcncral index to subject index. Also the ncwspapcr indcx such as The Times I~zdcx is 21 landmark in the history cf indcxing. 2) In China, thcs arc somc cvidcnccs that $Bizgluh(&), $ was the first indcx, but unforlunatcly the book itsclf has not been found as yet.

This study intends to analyze the library classification of agriculture in DDC, from the Int edition to the 21th edition. Since Dewey Decimal Classification(DDC) was the first published in 1876, number of total items increased significantly a newly-organized and subdivision of them in the 8th, 10th and 12th edition. According as the discipline developed and was specialized, the agricultural division in DDC was fractionized, and new subjects were continuously added to it. After that time the first edition, the major changes arranged an class and order in the 15th and 17th edition. That is to say, ‘Farm economics’ in 631.1 was relocated to 338.1 in the 17th and ‘Veterinary sciences’ in 619 was relocated to 636.089 in the 15th. Especially, up to now ‘Farm Economics’ deals with an important branch in the science of agriculture. Here the matter of argue heatedly arranges it from economics to agriculture.

A public librarian is an occupation, which requires long-term. continuous training and difficult study to acquire and cultivate professional knowledge and skills. It is a necessity to achieve new knowledge, information and skills via appropriate retraining. A training system is the method which gives chances of retraining to public librarians. After examining some of the problems with the existing training system, it is apparent that the direction of training system needs to be decentralized. That is each local branch should be autonomous in terms of new training for librarians. For the method of training system, each autonomous unit would integrate the different theories to apply to the community-at-large and invite practical specialists from the local community to lecture. The training classes would be elective in that the each librarian could choose the classes he/she wants to take and give them credits for that, but the certificate for the class would also go towards completion for the required technical training. Finally, the utilization of cyber-education should be introduced, and the library association's role strengthened, to help public librarians cultivate their specialties.

Viterbi decoder is composed of BMU(Branch metric Unit), ACSU(Add Compare Select Unit), and SMU(Survivor path Memory Unit). For high speed viterbi decoders, ACSU is the main bottleneck due to the compare-select and feedback operation. Thus, many studies have been advanced to solve the problem. For example, M-step look ahead technique and Minimized method are typical high speed algorithms. In this paper, we designed a bit-level ACSU(K=3, R=1/2, 4bit soft decision) based on those algorithms and switched the matrix product order in the backward direction of Minimized method so as to apply Code-Optimized-Array in order to reduce the area complexity. For experimentation, we synthesized our design by using SYNOPSYS Design compiler, with TSMC 0.18 um library, and verified the timing by using CADENCE verilog-XL.

Viterbi decoder는 크게 BM(Branch metric), ACS(Add-Compare-Select), SM(Survivor Memory) block 으로 구성되어 있다. 이중 ACSU 부분은 고속 데이터 처리를 위한 bottleneck이 되어 왔으며, 이의 해결을 위한 많은 연구가 활발히 진행되어 왔다. look ahead technique은 ACSU를 M-step으로 처리하고 CS(Carry save) number를 사용한 새로운 비교 알고리즘을 제안하여 high throughput을 추구했으며, minimized method는 block processing 방식으로 forward, backward 방향으로 decoding을 수행하여 ACSU 부분의 feedback을 완전히 제거하여 exteremely high throughput 을 추구하고 있다. 이에 대해 look ahead technique 의 기본 PE(Processing Element)를 바탕으로 minimized method 알고 리즘의 core block 을 bit-level 로 구현하였으며 : code converter 를 이용하여 CS number 가운데 redundat number(l)를 제거하여 비교기를 더 간단히 하였다. SYNOPSYS의 Design compiler 와 TSMC 0.18 um library 를 이용하여 합성하였다.
