      • 성공적 통합 정보 시스템 구축 사례 연구 : 우리나라 중소기업을 중심으로 Focus on the Small and Medium Companies

        정락채,권기대 龍仁大學校 1997 용인대학교 논문집 Vol.14 No.-

        This study has investigated small and Medium companies in terms of developing an integrated successful information systems through a Case study. The results showed that the information system of small and medium companies is in the beginning stage. Moreover successful factors are not able to define because of describing the information technology's vagueness.

      • 보일러 포화증기 회수중의 응축수 탱크내에서의 수격 현상에 관한 고찰

        安樂善 忠州大學校 1987 한국교통대학교 논문집 Vol.21 No.-

        A delivery valve has installed to a was out pump in order to control keeping off counter flow and delivery volume in case of an accident of out of order pump. Condensing water has been supplied to a boiler by circulation pump through a condensing tank Condensing tank contained condenser cooling system or boiler condensing water. A shutting down of a pump operation by sudden interception a circulation pump decreased cooling water or delivery volume of supplying water. By this a sudden water hammer is caused in the system. According to pump characteristic, driving condition of delivery valve the feature of geometry in system and condensing water condition, water hammer was changed and the destruction in system can be happened in violence. In this paper, I have made a numerical value analysis on the water hammer affected by the change of a section for materials in system applycating to driving condition of delivery value. Pump characteristic and a water hammer equation when the pump stopped suddenly.

      • 열역학 제2법칙에 의한 압축과정의 효율에 관한 고찰

        安樂善,申光燮 忠州大學校 1993 한국교통대학교 논문집 Vol.28 No.-

        I have studied the efficiency of compression procession by the second law of thermodynamics. I have obtained the result as following: 1) In case of heating discharge, it can be defined as other efficiencies if we are regarded as the position output instead of the negative input with quantity of changing into the exergy. 2) The exergetic efficiency stand in need of inviting atmospheric temperatures. 3) Conventional efficiencies of the adiabatic compression process such as isentropic efficiency and polytropic efficiency can be explained as exergetic efficiencies replacing the reference atmospheric temperature with temperature which can be determined in the process itself.

      • A Thyristor Macro-Modeling for Computer Aided Cycloconverter Simulation and Design

        黃樂壎 世明大學校 1992 世明論叢 Vol.2 No.-

        사이크로 컨버어터의 경우 임의의 초기 상태로 부터 정상 상태 계산을 위한 일반적인 방법으로 얻어진 결과를 논했다. 제안된 방법은 시스템 방정식의 공식화를 위해 Euler Backward Alogorithm과 Jocobian 계산이 이용되었다. 또한 연속적인 적분 기간에서 초기 상태에 대한 반복된 값의 계산을 위한 Newton-Raphson 방법을 이용했다. 그리고, 그 적용으로 제작장치의 실험결과와 같은 결과가 얻어졌다.

      • 열원에서의 증기응축을 위한 냉각장치의 랜킨사이클에 대한 고찰

        安樂善 忠州大學校 1988 한국교통대학교 논문집 Vol.22 No.-

        Heat engine that changes heat energy into mechanical work does heat exchange between high heat source and low while working fluid undergoes cycle process. When you design and operate a heat engine you should consider not only the cycle itself but the heat exchange process and should calculate the optimum condition. In high heat source there is a heat loss of itself owing to different temperature with surroundings and part of heat transmitted to working fluid in cycle also discharges directly into the air because of heat loss at pipe arrangement and the turbine. In this paper I examined on the output change and the maximum output condition in accordance with the operation condition of reversible cycle and on the operation condition of the cycle to calculate the maximum output by Rankin cycle. I studied on the typical Rankin Cycle by calculationg outputs with various operation condition and examined the results.

      • 墨子의 功利主義的 關心과 그 政治思想

        전락희 단국대학교 1998 論文集 Vol.32 No.-

        Mo Tzu's surname was Mo. his given name was Ti, and he was a native of the State of Lu. Both his birth and death date are difficult to ascertain. Various scholars have offered quite different conclusions. but the most reliable view seems to be that he was born about the Thirtieth year of the reign of the Chou King Ching(490 B. C.) and died about the Twenty-third year King Wei-lieh(403 B. C.). As for the events of his life, we know next to nothing, because of the lack of documentary evidence. Mo Tzu's universal love is the basic element of his political theories, and reverence for heaven, proving the existence of spirits, identification with the superior, and economy of expenditures are its branches. Anti-fatalism, anti-music, and simplicity in funerals are merely other issues upon which circumstances provoked him to take such stands. Mo Tzu's political theories found its starting point in the choice between benefit and harm, and went on to establish the doctrines of agreement with the superior, of the will of Heaven, and of the proof of the existence of spirits, to insure the practice of universal love. Mo Tzu, having established the agreement with the superior as a political sanction, still felt that to be inadequate: he thus proceeded to promote theories of the will of Heaven. and about the existence of spirits, in order to have religious sanctions as well.

      • 國民體育振興政策의 關係法領에 따른 行政行爲實態에 대한 調査硏究 : 國民體育振興法中 學校 및 社會體育振興關係法令을 中心으로

        朱洛瑞 師範大學 體育硏究所 1986 서울大學校 體育硏究所論集 Vol.7 No.1

        Modern states have guaranteed the right of economic and social live as well as the civil liberties, and also intervened actively in national life for the public benfit. In order to actualize these things, states assume the form of "Administrative state" built up the executive strength. Administration means the legal action which can realize the national aims, one is the aim for the existence and activity of nation itself, and the other is the social aim for the public benefit. Therefore, korea has adopted various policies enacted the law of Administration, and put it in operation on behalf of the performance of the aims. As a matter of fact, the performance of the policy for national existence, development and benefit clings to the establishment of proper national view through political education. Generally, education contains the dualism of educational view. So to speak, they are "Homo Sapiens" and "Homo Faber". If these two can correspond with each other and develop, the country will improve for sure. This study analyzes some problems resulted from training human bodies and the effectiveness of the law of National Physical Education. 1. People don't have sound mind due to the lack of experience, understanding, and participation in physical education. 2. When the law of National Physical Education was established, the assumption of omniscence, the adoption of best-fitted suggestion, the establishment of the best purpose, and the image of rational economic person were not considered. 3. The law of National Physical Education doesn't include the image of desirable future, the perspective of desirable development, the line of preferable actions, and the policy-intention. 4. It is so passive to participate in the physical activities in schools and work places, and to observe the law of Administration. The administrative function containing the execution and control of the law is very weak, and the advanced specialty is short. 5. The good understanding and participation in physical education should be made by the appropriate educational view, and as for establishing policies, optimal model must be introduced. The execution of the law of National Physical Education should have effect on everyone. And it is very urgent to suggest the concrete devices about the law of National Physical Education for the sake of making walfare state.

        정낙우 서강정보대학 1991 論文集 Vol.10 No.-

        This study is considered whether the dynamic reconfigurable dispersive management system can be formed or not by applying. "message oriented mechanism" or "data-gram" method which is transmitted to each message without prior establishment of communication route in the message communication method between process affiliated with different "groups". This paper presents a program abstraction so that autonomous processes, interacting on a resource to provide related service.
