전흥우,김명관,정금섭 한국정보통신학회 2002 한국정보통신학회논문지 Vol.6 No.6

셀룰러 뉴럴 네트워크는 국부적 연결특성을 가지고 있어 실시간 이미지처리에 적합한 뉴럴 네크워크이다. 또한 국부적 연결특징은 VLSI구현에 적합하다. 그의 응용분야는 패턴인식과 숫자인식 및 영상처리에 응용되고 있다. 본 논문에서, CNN은 전처리 단계로서 숫자의 특징점 추출에 이용된다. CNN을 이용한 그림자검출은 4내지 6방향으로 검출하여 숫자의 특징점을 방향별로 추출한다. 분류단계에서 이러한 형상자료는 다층BP뉴럴 네트워크의 입력벡터에 적합하도록 압축되어 입력된다. 실험결과 CNN을 통한 숫자인식은 굴림체의 경우96%이상의 인식율을 보여 만족할 만한 결과를 얻었다. Cellular neural networks(CNN) are neural networks that have locally connected characteristics and real-time image processing. Locally connected characteristics are suitable for VLSI implementation. It also has applications in such areas as image processing and pattern recognition. In this thesis cellular neural networks are used for feature detection in number recognition at the stage of re-processing. The four or six directional shadow detectors are used in numbers recognition. At the stage of classification, this result of feature detection was simulated by using a multi-layer back Propagation neural network. The experiments indicate that the CNN feature detectors capture good features for number recognition tasks.

CNN의 최적화에 관한 연구

정금섭,전흥우 金烏工科大學校 1998 論文集 Vol.19 No.-

Optimization is an important subject in solving engineering problems. One conventional searching technique for finding the global minimum is to use mean field annealing. Mean field annealing is a deterministic approximation to simulated annealing. The basic idea is to replace stochastic binary neurons, say with two binary states xi = ±1. by analog neuron with continuous output constrained between -1 and +1. In this paper the cellular neural networks (CNN) with mean field annealing is studied and simulation results for edge extraction using annealed CNN are presented. These simulation results show that the un-annealed CNN has a local minimum problem. but the annealed CNN finds the global minimum solutions in a very efficient way and the value of the energy function in the steady states is independent of the initial states.

디지탈적으로 프로그램이 가능한 CNN칩 설계

류성환,전흥우 金烏工科大學校 1998 論文集 Vol.19 No.-

In this paper, the digitally programmable 6×6 cellular neural network chip is designed and the circuit operation is confirmed by the HSpice simulation of edge detection and hole filling. The designed cellular neural network allows for increased flexibility compared to the analog tuning mode due to the fact that synapse weights can be both programmed and stored digitally. The network considered in this design is a current mode cellular neural networks. Since the number of different weights is very small for this cellular neural networks. the programmability issues can be easily incorporated by just adding several global control lines. And the current mode circuit also provides the simplicity over voltage mode circuit.

신경욱,박재우,정금섭,전흥우 金烏工科大學校 1997 論文集 Vol.18 No.-

A cellular neural network(CNNs) is a massively parallel computing architecture made of simple processing elements which are locally connected. Therefore, the CNNs have a potential to process information in real time, and when implemented in a silicon allows for very simple structure and reduced area. In this paper the current mode cellular neural networks simulator is implemented and simulation results for edge extraction, noise removal and shadows detection are presented. This simulator can be applied to the image processing, the pattern recognition and the circuit parameters determination.

전흥우,신건순 金烏工科大學校 1991 論文集 Vol.12 No.-

In this paper, logical expression to truth table translation program using YACC is described, which can be used to generate the truth table for the input of logic minimizer, PLA folding and layout program. YACC (Yet Another Compiler Compiler) is used to describe the logical expression to the program. The YACC program generator provides a general tool for describing the input to a computer program, and can be used to develope the program having a complex and general input. This program also contains a simple logic minimization and feedback loop handling faculty.

일제강점기 강원지역 형평운동(衡平運動)

전흥우(Jeon, Heung-Woo) 강원대학교 인문과학연구소 2013 인문과학연구 Vol.0 No.38

이 연구의 목적은 기존의 국내 형평운동 연구에서 주목받지 못했던 지역, 특히 강원지역의 형평운동을 고찰함으로써 국내 형평운동 연구의 지평을 넓히려는 데 있다. 주지하다시피 일제는 3.1운동 이후 무단통치에서 문화정치로 통치전략을 수정했고, 이는 언론ㆍ출판ㆍ집회ㆍ결사 등 최소한의 자유가 허용되는 계기가 되었다. 그 결과 1920년대에 한글신문이 발행되고, 수많은 사회단체가 폭발적으로 생겨나 각 방면에서 활발한 사회운동이 전개되기도 했다. 형평운동(衡平運動)은 이런 역사적 시공간에서 탄생한 신분해방운동이다. 형평운동은 1923년 4월 진주에서 형평사(衡平社)가 창립된 이래 빠른 속도로 전국에 확산되었는데, 형평사는 1935년 친일적인 대동사(大同社)로 변질되기까지 백정계급의 대변자로 신분해방운동을 전개하며 전국적인 조직으로 성장하였다. 이러한 시대적 조류에 발맞춰 강원지역 형평운동 또한 1923년 말에서 1924년 초부터 시작되었다. 춘천ㆍ화천을 시작으로 횡성.원주 등 영서지역에서 먼저 시작된 강원지역 형평운동은 1925년에는 강릉ㆍ삼척ㆍ울진 등 영동지역으로 파급되어 1927년까지 최대 17개의 지역조직을 설립하였다. 강원지역 형평사 각 지사 및 분사의 사원은 한 때 200여 명에 달했던 원주를 제외하고는 대부분 기껏해야 수십 명에 불과하였지만, 백정에 대한 사회적 차별반대와 경제적 생존권 수호, 그리고 취학 및 야학 등 계몽적 교육활동을 적극적으로 전개하였다. 강원지역의 형평운동에서 조선일보ㆍ동아일보ㆍ시대일보 등 신문사 지국의 기자로 활동하며 지역사회운동을 주도한 청년 및 지식인들과 여타의 사회운동가들의 역할을 빼놓을 수 없다. 다른 지역과 마찬가지로, 강원지역에서도 이들의 지원과 협력에 힘입어 형평운동은 성장할 수 있었다. The purpose of this paper is to extend the prospect of the study on the Hyoung-pyoung Movement by considering the Hyoung-pyoung Movement in Gang-won region. It is known that after the March First Independence Movement, Japanese Empire changed the governing from ‘military government’ to ‘cultural rule’ and admitted of a minimum freedom of press, publishing, meeting, and association. As a result, the Han-geul newspapers were issued, and a number of social groups appeared so explosively in the 1920s that social movements were animatedly developed in various fields. In this historic space and time, the Hyoung-pyoung Movement began as a status emancipation movement. The Hyoung-pyoung Movement spread across the nation rapidly after Hyoung-pyoung-sa was founded in April 1923. Hyoung-pyoung-sa developed a status emancipation movement as a spokesman of the butcher class and grew into a national organization until it was transformed into a pro-Japanese Dae-dong-sa in 1935. With those current times, the Hyoung-pyoung Movement in Gang-won region was also started at the end of 1923 or the beginning in 1924. It first started in Young-seo region as Chun-cheon, Hwa-cheon, Hoeng-seong, Won-ju etc and spread to Young-dong region as Gang-reung, Sam-cheok, Ul-jin etc in 1925, and established up to 17 regional groups by 1927. With the exception of Won-ju in which the number of members reached 200, in most of Hyoung-pyoung-sa branches, the number of members was only a few dozens of people. However they developed actively campaigns against social discrimination, actions for protection of their economic rights to live, and enlightening educational activities such as sending their children to school or operating the Evening School. It is not permitted to exclude, in the Hyoung-pyoung movement of Gangwon region, the role of social activists and other intellectuals and youth who act as a reporter of newspaper bureau of Chosun Ilbo, Dong-A Ilbo, and Sidae Ilbo, and led the community movement. In this region as well as the others, thanks to their support and cooperation, the Hyoung-pyoung movement was able to grow up.
