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.

2차원 어레이를 이용한 Vector-radix 2차원 고속 DCT의 효율적인 VLSI 구현

신경욱,전흥우,강용섬 金烏工科大學校 1993 論文集 Vol.14 No.-

This paper describes an efficient array algorithm for parallel computation of vector-radix two-dimensional (2-D) fast discrete cosine transform(VR-FCT), and its VLSI implementation. The proposed array algorithm features architectural modularity, regularity and locality, so that it is very suitable for VLSI realization. Also, no transposition memory is required. It has the time complexity of ?? for (N X N) 2-D DCT, where ?? is the number of non-zero digits in canonic-signed digit (CSD) code. An array core based on the proposed array algorithm is designed with ISRC 1.5㎛ double metal N-Well CMOS technology. A hierarchical design approach based on Bit-Slice Unit (BSU) is adopted to achieve simple design and regular interconnections. The designed array core consists of 64 PE's arranged in 8 rows 8 columns, and it contains about 98,000 transistors on an area of 138㎜²excluding control logic block. From simulation results, it is estimated that (8X8) 2-D DCT(??) can be computed in about 0.88㎲ec at 50MHz clock frequency, resulting in the throughput rate of about 72 Mega pixels per second.

Rural of Koreas has rapidly changed through the process of industrialization and urbanization. During past 30 years, development differences between urban and rural, metroplitan area and area derived from a highly economic growth, bring about dual specialization that deepens overpopulation and sparsity. Therefore, with a new concern about rural, necessity of rural development policy that developes a settlement and life area for settlement for ensuing stablized settlement and living activity of rural people, has been drived step by step. For rural welfare establishment that is settled and good hereafter, this study aims at attempting a theoretical approach about the way of development for rural settlement as a new rural development strategy through examination of today's rural reality, under assumption that rural people must be able to obtain stable jobs and to be pleasant without leaving rural area, and rural settlement to be able to enjoy urban advantages must be realized. Therefore, items that must be obtained basically rural area to be a human settlement space are equipment connected with a dwelling house, production, consumption, job relaxation, infrastructure connected with transportation or communication network and environment. By the way, the best function of a human settlement space makes a basic pleasant settlement area to be in the middle of that. Then rationalization of land use must be realized as being a best condition for human life around space of a dewelling house. Besides, spacial accessibility about all equipment of inhabitants must be easy. That is, economic distance, social distance and cultural distance as well as spacial distance must be included. Also, those spacial functions must be realized on a basis of suitable enironment for a human settlement life. At the same tiem, the upper area must be connected with the lower area as the system of spacial settlement in settlement space. But truely, as rural people can't satisfy with services of the surrounding rural areas, they desire better city or metroplitan. The these problems bring about inequality between urban and rural. Therefore, here are urgent reasons that must be done rearing of rural central town and rural integrated development of unit area. So, these dys, to correct maldistribution of land use and inequality of settlement space that Korean society faces on, new strategies of rural integrated development for lift area for settlement than gives the meaning. That rural areas become like a place for human settlement life will be able to be chosen in the view of humanism. The say of thinking of rural residents(Jukans-myun, Anseong-gun, Kyeonggi-do) was surveyed in order to develop new rural settlement planning. From the data collected in this survey, rural life-style, view on traditional rural life, agriculture, farming, agri-policy, social attitude, and degree of satifaction of rural life, etc, were analyzed. Firstly, most of rural residents interviewed in this survey have the opinion of not leaving their home village if living conditions improved to a reasonable level in the near future. In decision-making process of village affairs, they want to participate actively and equally. Secondly, in spite of their acceptance of agriculture as a vital sector destined to national security, most of them think that framing should be little of promise. Thirdly, they have the negative attitude to urban-oriented social valued and also to the agricultural policy, while seeking consolation through human and traditional viewing of rural life style. Therefore, in the development of new rural settlement model, idea-making should be directed to the betterment of communal value of village life, stability of rural economy, rationalization of rural life style and enhancement of rural-type happiness.

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.

( Jae Woo Lee ),( Hyun Jae Lee ),( Choong Jae Lee ),( Su Yel Lee ),( Byeong Kyou Jeon ),( Heung Seog Bae ),( Kyoung Rai Cho ) 한국응용약물학회 2011 Biomolecules & Therapeutics(구 응용약물학회지) Vol.19 No.1

In this study, we investigated whether ambroxol significantly affects secretion, production and gene expression of mucin from cultured airway epithelial cells. Confluent primary rat tracheal surface epithelial (RTSE) cells were pretreated with adenosine triphosphate (ATP) for 5 min and then treated for 30 min with ambroxol to assess the effect on mucin secretion using ELISA. Additionally, confluent NCI-H292 cells were pretreated with ambroxol for 30 min and then stimulated with EGF or PMA for 24 h. The MUC5AC mucin gene expression and mucin protein production were measured by RT-PCR and ELISA. The results were as follows: (1) ambroxol did not significantly affect ATP-induced mucin secretion from cultured RTSE cells; (2) ambroxol inhibited the production of MUC5AC mucin protein induced by EGF and PMA in NCI-H292 cells; (3) ambroxol also inhibited the expression of MUC5AC mucin gene induced by EGF and PMA in NCI-H292 cells. This result suggests that ambroxol can inhibit the production and gene expression of MUC5AC mucin, by directly acting on human airway epithelial cells.
