‘Language’ is an important tool of communication and thoughts for human being. And the people’s ability of foreign languages of a country represents its national competitiveness and could be a criteria of a way of thinking. Therefore, foreign language education is very important to maintain the relationship between countries in the era of internationalization. In addition, using and speaking foreign languages could help all of us to exchange and share the thoughts and culture with others in foreign countries. When a country establishes a policy of foreign language education, it is necessary to consider a various kinds of factors beyond the basic aspects of language education. Also, foreign language education could represents cultivating intellectual capacity of the people, and furthermore, it has very much related to future development of the country in the fields of society, politics and economy. Since geographically, the two countries, Taiwan and Korea are very close each other, economic performances between the countries have been very active. The purpose of this paper is to help establish the second foreign language education policy and prepare for improvement plans in the future by examining the similarities and differences between the high school second language education policies of Taiwan and Korea.

전력선모뎀 및 조광제어 안정기를 이용한 400W Metal Halide Lamp의 조광제어 시스템 개발

박종연,최왕섭 江原大學校 産業技術硏究所 2009 産業技術硏究 Vol.29 No.B

In this paper, we developed remote dimming control system of electronic ballast for 400W metal halide lamp. This ballast could limit ignition current and soft start-up technique by the inverter with LCsCp resonance tank. The dimming circuit can dim from 400W to 200W by varying of the inverter switching frequency. The PLM consists of coupling circuit, BPF(Band-Pass Filter), FSK(Frequency Shift Keying) Modem and μ-controller(Micro Controller). By coupling electronic ballast with PLM, the system that able to dimming the lamp through PLM is demonstrated by experimental results.

주파수 변조 기법을 이용하여 음향공명 현상을 제거한 1[kW] 메탈 핼라이드 램프용 전자식 안정기 개발

박종연,이봉진,Park, Chong-Yun,Lee, Bong-Jin 한국조명전기설비학회 2008 조명·전기설비학회논문지 Vol.22 No.2

본 논문은 주파수 변조 기법을 도입하여 메탈 핼라이드 램프의 음향공명 현상을 제거한 수동 PFC 구조의 전자식 안정기를 설계 및 구현하였다. 제안하는 안정기는 EMI 필터, 수동 PFC 회로, 풀 브리지 인버터 및 LC 공진 타입의 점화기, 그리고 음향공명 현상을 제거하기 위한 회로로 구성되었다. 주파수 변조 기법의 도입으로 단일 주파수 구동시 문제점이였던 램프의 수명 경과에 따른 음향공명 대역이 변화와 동일한 크기의 방전관이라도 램프 제조 사마다 아크 튜브 내부에 봉입되는 물질과 압력차에 의한 음향공명 대역의 차이를 해결하였다. 개발된 prototype 1[kW] 메탈 핼라이드 램프용 전자식 안정기의 광변환 효율, 입력 PF, 입력 전류의 THD, 그리고 전력 변환 효율을 측정함으로써 성능을 입증하였다. This paper presents the design and imelementation of an electronic ballast with a passive PFC structure from which acoustic resonance of the metal halide lamp was removed by introducing the frequency modulation(FM) method. The proposed ballast consists of an EMI filter, passive PFC circuit full-bridge inverter, LC resonance type igniter and a circuit for removing acoustic resonance. The FM method solved two problems associated with single frequency driving: variation of the acoustic resonance range according to lamp aging and the acoustic resonance range discrepancy caused by different materials sealed inside the arc tube and their pressures for arc tubes of identical sizes from different manufacturers. Performance of the prototype developed for this study of the electronic ballast for 1[kW] metal halide lamp was verified by evaluating its optical conversion efficiency, input PF, input current THD and power conversion efficiency.

풀 브리지 인버터에 적합한 메탈 핼라이드 램프용 점화기의 해석 및 설계

박종연,이봉진,Park, Chong-Yun,Lee, Bong-Jin 한국조명전기설비학회 2007 조명·전기설비학회논문지 Vol.21 No.8

본 논문은 반도체 소자의 사용없이 구성된 LC 공진 타입의 점화기를 분석하고 설계하였다. 일반적으로 사용되고 있는 점화기는 다이악, 아크갭, SCR과 같은 반도체 소자가 사용된다. 이러한 반도체 소자의 사용으로 인해 회로의 구성이 복잡해지며 신뢰성이 저하된다. 따라서 본 논문에서는 수동 소자로만 구성된 점화기 회로를 분석 및 설계하였으며 제안한 점화기는 램프의 정상 상태에서는 영향을 미치지 않는다. 수학적 분석, 컴퓨터 시뮬레이션과 1[kW] 메탈 핼라이드 램프용 전자식 안정기를 제작하여 실제 적용해 봄으로서 제안한 점화기의 유용함을 증명하였다. A high ignition voltage is required to turn on the metal halide discharge(MHD) lamp. The igniter with high frequency resonance circuit needs more devices, such as sidac, arc-gab, SCR(silicon control rectifier), DIAC and so of which increase the complexity and decrease the reliability of the ignitor. This paper analyzes and designs a simple LC resonance type igniter without any extra switch devices. Moreover, the igniter will not influence the steady-state operation of the lamp. Through the mathematical analysis, the computer simulation and experiment results of a prototype ballast for 1[kW] metal halide lamp(MHL) lamp, the proposed igniter was verified to be effective.

조도 제어용 ASK 및 FSK 전력선 모뎀의 성능 평가

박종연,최현희 강원대학교 정보통신연구소 2008 정보통신논문지 Vol.12 No.-

In this paper, two type of power line modems are evaluated to realize the lamp control system using the power line communication. One is FSK modem using DS/SS and the other is the manchester coded ASK modem. Both modems apply (7,4) hamming code to correct errors. There are two kinds of used loads ; the electronic ballast and the magnetic ballast. The Electronic ballast is for a 250Watt HID lamp, a 50watt florescent lamp and a 50watt induction lamp. The Magnetic ballast is for a 250watt HID lamp. Bit errors are measured between the main modem and the ASK or the FSK sub-modems in loads at equal distances. As a result, it is estimated that the FSK modem is more appropriate than the ASK modem in terms of the lamp dimming system. And we also concluded that the (7,4) hamming code is not suitable for ASK application In the lamp control system.

전력선 통신 채녈의 단 구간 변화에 대한 분석

박종연,최원호,정광현 江原大學校 産業技術硏究所 2007 産業技術硏究 Vol.27 No.B

The power line channel has time-variant characteristics caused by various kind of electrical devices. This characteristics are synchronized with the main voltage by their own characteristics. The main factors of disturbance are the variation of the channel impedance and noises, In other papers [2] [3], the synchronous noise modeling has been achieved. But the modeling is not satisfied simultaneously with the time domain and the frequency domain and there are not any discussion about short-term variations of the channel impedance which cause to the signal fading. Therefore, this paper researched to solve problems about the signal fading by analyzing the short-term variation of the channel impedance, and proposed the synchronous noise modeling which is satisfied simultaneously in the time domain and the frequency domain.

공공기관 기록관리 평가제도의 현황과 개선방향

박종연,이해영,서효선,김우희 한국기록관리학회 2019 한국기록관리학회지 Vol.19 No.1

It has been more than ten years since the evaluation system of records management in public institutions was introduced. Over the past decade, the evaluation system of records management in public institutions has contributed to the professional deployment of records management and the expansion of the records infrastructure. However, at this time, it is necessary to introduce a new evaluation system because of various problems including ranking and insufficiency of feedback measure. Therefore, we attempted to identify the problems and suggest the direction of improvement by analyzing the status of the evaluation system for records management in public institutions and collecting opinions from various sectors. The directions of the new institutional evaluation on records management based on the analysis of the problems are a step-by-step introduction, the selection of customized evaluation indicators according to institutional characteristics, the introduction of the governance system, self-evaluation by selecting autonomous indicators of institutions, and the strengthening of the consulting function of the National Archives of Korea. 공공기관에 기록관리 평가제도가 도입된 지 10년이 지났다. 지난 10년간 공공기관의 기록관리 평가제도는 기록물관리전문요원 배치와 기록관인프라 확충에도 기여하였으나, 현 시점에서는 서열화, 환류조치의 미흡 등 여러 가지 문제점들로 인하여 새로운 평가체제를 도입할 필요성이 제기되고 있다. 이에 기록관리 평가제도에 대한 변화과정 검토를 통해 현황분석을 진행하였고, 전문가 간담회, 현장 방문 등 다양한 방식의 의견수렴을 통해 문제점을 확인하고 개선방향을 제안하고자 하였다. 여러 문제점 분석에 기반하여 제안한 새로운 기록관리 평가의 방향은 단계별 도입, 기관의 특성에 따른 맞춤형 지표선정, 거버넌스 체계의 도입, 기관의 자율적 지표선정에 의한 자체평가, 그리고 국가기록원의 컨설팅기능 강화 등이다.
