  • Many formats are used for recording and processing in the research of earthquake seismology and earthquake engineering. It is very difficult to program the Reading and writing algorithm for data processing because fill formats are very different from each other. It is suggested new file format of Korea Standard earthquake data (KSED) two types of ASCII and binary that are read and written easily. The Program package of basic data processing (Analyst) which has function of basic filtering spectrum analysis event gathering phase picking and location is developed In addition this program supports file transformation from another format(Mini SEED OMD K2) to KSED format.

  • The KORMARC format for authority data defines the ales and conventions (tags, indrators, subfield codes and coded value) that idenbfy the data elements in KORMARC authority records. This document is intended for the use of personel involved in the creation and maintenance of authority records as well as those involved in the deslgn and maintenance of systems for the communication and praxsmg of authority records. The format is developed on the basis of USMARC f o m t for authority data. And for the compatibility, the KORMARC format for bibliographc data is taken into account.

  • Documentation is a typical method that helps students to understand a program for implementation and execute error correction and maintenance cost-effectively. Guidelines for components that organize documentation should be provided to enable to express computational thinking and such components also should be linked to coding process. In this paper, we focused on the documentation format to guide elementary school students, who were beginners in computational thinking, to express computational thinking. The improvement in the expression of computational thinking was analyzed based on the documentation format applied to the class, and practical tips on the importance of components organizing the documentation format were proposed.

  • Backward compatibility is one of the key issues for radio equipment supporting IEEE 802.11, the typical wireless local area networks (WLANs) communication protocol. For a successful packet decoding with the backward compatibility, the frame format detection is a core precondition. This paper presents a novel frame format detection method based on a deep learning procedure for WLANs affiliated with IEEE 802.11. Considering that the detection performance of conventional methods is degraded mainly due to the poor performances in the symbol synchronization and/or channel estimation in low signal-to-noise-ratio environments, we propose a novel detection method based on convolutional neural network (CNN) that replaces the entire conventional detection procedures. The proposed deep learning network provides a robust detection directly from the receive data. Through extensive computer simulations performed in the multipath fading channel environments (modeled by Project IEEE 802.11 Task Group ac), the proposed method exhibits superb improvement in the frame format detection compared to the conventional method.

  • 본 연구는 12명의 컴퓨터 작업자를 대상으로 테이터 입력 방법과 소음 수준이 데이터 입력 작업 수행도에 미치는 영향을 분석하였다. 다른 형태의 Database Format 및 Interaction Technique을 갖는 3가지 데이터 입력 방법(Card Format/Keyvoard 입력, Card Format/Menu방식을 이용한 Mouse Click, Table Format/Keyboard 입력)과 소음의 2수준(60 .approx. 65dBA, 80 .approx. 85dBA)을 독립실험인자로 채택하였다. 에러 문제를 효율적으로 다루기 위해 에러 방지(error prevention)와 에러 관리(error management)의 두 가지 전략을 고려하여 두 가지 실험을 실시하였다. 실험 1에서는 에러를 효율적으로 예방할 수 있는 데이터 입력 방법 및 작업 환경을 알아보고자 데이터 입력작업 완료시간과 데이터 입력 시 발생하는 에러의 수를 종속변수로 측정하였으며, 실험 2에서는 에러의 효율적인 관리를 위한 데이터 입력 방법 및 작업 환경을 알아보고자 에러수정시간을 종속변수로하여 측정하였다. 통계분석결과, 높은 소음 수준하에서 에러수정시간이 많이 걸렸다. Form Fill-in 형식으로 입력하는 방법을 이용했을 경우 입력작업 완료시간이 적게 걸렸으며 Card format을 갖는 입력방식을 이용했을 때 적은 에러 수정시간을 나타내었다.

  • This paper presents the FPGA implementation of efficient algorithms for approximating exponential function based on floating point format data. The Taylor-Maclaurin expansion as a conventional approximation method becomes inefficient since high order expansion is required for the large number to satisfy the approximation error. A format converter is designed to convert fixed data format to floating data format, and then the real number is separated into two fields, an integer field and an exponent field to separately perform mathematic operations. A new assembly command is designed and added to previously developed command set to refer the math table. To test the proposed algorithm, assembly program has been developed. The program is downloaded into the Altera DSP KIT W/STRATIX II EP2S180N Board. Performances of the proposed method are compared with those of the Taylor-Maclaurin expansion.

  • As industrial standard data, the STL format which approximates three dimensional CAD model to triangular facets, is used for RP(Rapid Prototyping) system in recent days. Because most RP system take the only form of two dimensional line segments as an input stream inspite of its imperfectness while converting into STL format, a CAD model is converted into a standard industrial format which is composed of many triangular facets. The error verifying process is composed of four main steps, and these are 1) Remove facets with two or more vertices equal to each other. 2) Fix overlapping error such as more than three facets adjacent to anedge. 3) Fill holes in the mesh by using Delaunay triangulation method. 4) Correct the wrong direction and normal vectors. This paper is concerned with serching the mentioned errors in advance and modifying them.

  • Newspaper Article Information is an important source of information on social phenomenon with historical value. The development of computer and technology of information communication enables the construction of Newspaper Article Database by CTS and service through computer communication. It made it possible for the peoples to utilize the Newspaper Article Information easily. However, it is very difficult to utilize the currently prevailing system. There are differences in classification system of Newspaper Article Database and the Data Display Format. This survey aims to review the characteristics of Newspaper Article Database and current domestic computer communication service system. By comparing the classification system of Retrieval Menu and Data Display Format, I intended to suggest the standardized way of utilization which enables the users utilize them more easily and conveniently. The results of this survey is as follows : 1. More sub-divided distinction of classification item is required. 2. Separate classification item should be established for the distinction of article form which is very difficult to classify the subject. 3. Data Display Format should be equi n.0, pped with standardized format and signal which enables the users recognize it easily.
