Hae-In temple is located in Gaya Mountains, Hapcheon-gun, Korea and a thousand years old monastery. Tripitaka Koreana has been preserved during 750 years as good condition in Hae-In temple. The preservation technology is summarized as the passive design methods harmonized with the nature perfectly. Haein temple have dealt with a flow fields in the storage hall. In this study, an indoor and outdoor flow fields in the precincts of Haein temple were analysed with field measurement and numerical simulation. On the basis of the field measurement results, the restoration cases such as rearrangement of Tripitaka Koreana and relocation of the rear fence of Biro-Jean were analyzed with CFD.

Translation 과정에 영향을 미치는 RNA의 이차 구조와 구조의 존재하는 위치에 대한 영향을 조사하기 위해 본 연구에서는 model system으로 사람의 ferritin 유전자를 이용하였다. Ferritin 유전자의 5‘UTR, 단백질의 coding 지역내, 3’ UTR 등 3가지 위치에서 변형된 이차구조 인자를 이용하여 ferritin 단백질의 생성량을 in vitro translation을 이용하여 비교 측정하였다. 이 가운데 5‘ UTR에 존재하는 RNA 이차구조만이 ferritin 합성을 저해하였다. Genetic controls of cell metabolism and differentiation involve translational regulatory mechanism. Iron-responsive elements located within 5' or 3' untranslated regions(UTRs) are utilized for translational specific mRNAs. To identify the locations of structural elements utilized for translational regulation of mRNA, we modified and tested the roles of structural elements located within the 5', 3' UTR or coding region of ferritin. Our data suggest only 5'UTR element within ferritin is important for translational regulation.

As the amount of data is increased and complicated, some accidental or intentional infiltrations to the computer system itself and information in it are occurred. Therefore we must be currently able to safeguard from these infiltrations and accidents. In this paper, we investigate various types of invasions and propose protection mechanisms and methods to evaluate these in consideration of costs, environments, effectiveness, etc. 1. 서 론 2. 컴퓨터 시스템의 안전과 보안의 침해 요인과 대응책 3. 컴퓨터 시스템의 운영체제 측면에서의 안전과 보안 4. 평가 및 분석 5. 결 론 As the amount of data is increased and complicated, some accidental or intentional infiltrations to the computer system itself and information in it are occurred.

사람 L-ferritin을 연구하기 위해 RT-PCR을 수행하여 ferritin 유전자를 T7 promoter expression vector에 subcloning시켜 대장균 내에서 발현시켰다 대량 발현된 L-ferritin의 발현 비율을 조사하였으며, SDS-PAGE 및, western blotting을 이용하여 재조합 I-ferritin의 발현을 확인하였다 Iron is an essential inorganic element for the growth of all forms of life. Iron is stored in cells in the form of ferritin. Human ferritins are composed of two types of subunits, Heavy(H)-and Light(L)-subunit. In this study, Human L-ferritin gene was isolated from human cell and subcloned into a bacterial expression vector. L-ferritin was overexpressed from E. coli BL21(DE3). By SDS-PAGE and western blotting, expressed protein was confirmed as feritin.

신경회로망에서 뉴런간의 연결도를 이용한 4색 배치 문제 해결 알고리즘

In this paper we have proposed a method for solving a four-coloring problem using adjusted information transmission between adjacent neurons in neural networks. These algorithms are based on McCclloch-Pitts binary neuron model neural networks. If a map shares n regions, a 4×n neural array is used to color a map of n regions where each neuron as a processing element performs it. By programming these algorithm by a C-language in IBM PC 486 DX and adapting it to various examples, we have showed the ability of our system. If one neuron is selected among four neurons, the strength of order three neurons is wakened. So, by transmitting the information of selected neuron, adjacent neurons cannot share the same color.

We have developed academic affairs using file system since 1978. But, their are many problems, for example, file handing, redundant data, security, privacy, recovery, operators misoperation. In this paper, we designed and implemented academic affairs with total system using DBMS installed at MV8000 system and showed many reports such as roll books and lists of student's records and various kinds of statistical reports according to the inputs from each student and professor.

차세대 인터넷 도입을 위한 경계 라우터의 성능분석에 관한 연구

이수욱,황성호,임해진 三陟大學校 2004 論文集 Vol.37 No.-

The IPv6(Internet Protocol version 6), a next generation internet protocol. was standardized to solve the problems of the IPv4(Intemet Protocol version 4). However. the IPv4 could not be actually converted to the IPv6 at one time. Therefore. the transition mechanism is thought to be very much important to be compatible with the IPv4 naturally and convert to the IPv6 network gradually. Despite of the development of various kinds of the transition mechanism, the IPv6 network was not expanded. The research was mainly made not for current system environment but for technical purposes. This paper investigated the performances through the transition mechanism and examined proper ways being applicable to current environment.

이종연,임해진 三陟大學校 2000 論文集 Vol.33 No.1

This paper proposes a framework of an intelligent geographic information system(IGIS) for tourist guide which reflects road status, traffic volume, hotel facilities, seasons, travel intervals, costs, persons, and famous places which they should want to travel. Starting with reviewing the characteristics of pervious spatial models, this paper presents basic concepts, design considerations, knowledge bases, and user interfaces for the proposed model and evaluates and execution process of the system. In addition, we describe the concatenation methods of related information systems for the intelligent geographic information system. Finally, the primary difference between the proposed knowledge database and its processing system and an intelligent, object-oriented geographic information system, called GeoViewer, is reviewed through comparing with their characteristics.

The purpose of this article is to establish some principles in helping students study in order to enhance the ability of solving problems reasonably by using fundamental mathematical skills, and to bring forth the improvement of mathematics education by using the above mentioned principles. In this work we investigate the following subjects ; (1) Fundamental concepts and strategies of teaching students for mathematics problem solving achieved in nineteen eighties in and out of Korea. (2) Current status of problem solving ability of middle and highschool students and teachers. (3) We first made 「motivation-advice cards」 about the problem solving strategy according to the classification of problem solving thought format, and then we used them in highschool classes. We test the result. We obtained the following conclusions ; (1) The style of test problems has to be changed from multiple choice form which is widely used in various evaluation examinations to writing style. (2) Studies of teaching method to help students extend their creativity, and making good problems and invention of instructive devices are required. (3) After making the students aware of the importance of problem solving strategy and of the way how to use it, we have to lead the students to acquire the habit of using them.
