퍼지 제어기를 이용한 차량의 자율주차 시뮬레이션

박재현,김승철,한창훈,박종오,임영도 東亞大學校 附設 情報通信硏究所 1998 情報通信硏究所論文誌 Vol.6 No.1

In a case of driving beginnners, it is very difficult to park a car perfectly because driver's knowledge makes more errors than intelligent mechanism when they are performed repeatedly. However skilled drivers be of experienced knowledge are able to park a car quickly. In this paper, we analyzed driving patterns of skilled drivers, designed the fuzzy controller to park based on it, and perform auto-parking simulation of a car using that controller.

NW6005를 이용한 발신자 번호 추적 장치 개발

이다한,박찬진,박찬국,이성철,박민경,윤병우 경성대학교 공학기술연구소 2012 공학기술연구지 Vol.18 No.-

NW6005의 칩을 이용하여 발신자 번호 데이터를 추적하는데 성공하였고 그 뿐만 아니라 두 개 이상의 전화에서 발신자 번호 데이터를 수신하더라도 데이터가 깨지지 않고 제대로 수신하는 알고리즘을 구상하였고 그에 대한 실험은 성공적이었으며 또한 전화 통신중의 오류에 대한 문제도 해결하였다. 최종적으로 4개의 전화선에서 하나 또는 동시에 발신자 번호를 추적하여 시리얼 통신으로 데이터를 전송시키는 장비를 개발하였다.

강소기업의 지속성장을 위한 경영권 승계 철학

박기찬(Ki-Chan Park),이윤(Yune Lee),이한구(Han-Gu Lee) 피터드러커 소사이어티 2014 창조와 혁신 Vol.7 No.1

본 사례연구는 창업으로 성공한 창업가(entrepreneur)의 경영권 승계에 대한 철학을 그의 사업 역정을 통하여 살펴보는 데 목적이 있다. 흔히 경영자(manager)의 눈에는 돈이 안 되는 문제부터 보이지만, 사업가(businessman)의 눈에는 돈이 되는 사업부터 보인다고 한다. 과연 우리나라에 창업 사업가로서 기업가 정신(entrepreneurship)을 잃지 않으면서 한편으로는 경영자로서 '創業보다 어렵다는 守成의 길'을 성공적으로 영위해 온 인물은 얼마나 되는가? 그리고 언젠가는 자신의 사업체를 누군가에게 물려줄 수밖에 없는 상황에서 경영권 승계는 과연 어떻게 이루어지고 있는가? 이에 대한 논의를 위해 본 사례는 코텍 이한구 회장과의 인터뷰를 바탕으로 사업가이자 최고경영자로서 사업과 인생에 대한 관점 및 그의 경영권 승계에 대한 철학을 분석함으로써 강소기업으로 성공한 창업가(entrepreneur)는 물론 대기업의 경영권 승계 관행에 대한 새로운 시사점을 던지고자 한다. The purpose of this case study is to analyze the philosophy of an entrepreneur (CEO and Chairman of Kortek) being appeared in the process of management succession. The 27 years history of a start-up firm introduced in this analysis maneuvered its challenging business based on Chairman Lee's business insights and philosophy since its foundation in 1987. Kortek, as a hidden champion, is the No. 1 in the field of Gaming Video Display Monitor delivering more than 70% of Video Slut Machines in the U.S. market. Compared to the ordinary managers who are in seeking of dysfunctions of daily management and operations, the founder and current CEO and Chairman Han-Gu Lee pursued to catch out the money-making businesses with his talented entrepreneurship. Despite of his unprecedent success as an industrial display monitor maker, recently he has been deliberately considered about the management succession scenarios for the vision of his cherished Kortek to keep as a sustainable company. In this case study, we analyzed the 3 scenarios being evaluated during more than 2 years by Chairman Lee. And as the result and performances after his decision to accept M&A with IDIS Holdings show a sustainable growth, we could extract strong implications not only for the Korean CEOs of hidden champions who have experiences as start-up founder but also other major companies being faced with such an agony in management succession.

용액 중합에 의한 전도성 Poly(amide)/Polypyrrole 복합체의 제조와 그 전기적 성질

박연흠,안찬호,한명희 成均館大學校 科學技術硏究所 1993 論文集 Vol.44 No.1

Poly(amide)/Polypyrrole composite films were prepared by solution ploymerization method. The films obtained by this method exhibited high conductivities. After polymerization of pyrrole for 1 hr, composite films showed the conductivity as high as 10^-3∼10^-2 S/cm and it increased with increasing the concentration of oxidizing agent. The stability of conductivity to ambient air exposure was excellent. As the result of the thermal characterization of composite films by TGA, we found that the composite film was thermally stable.

This study deals with comprehensive landscape restoration and reorganization of Dagsil Village including physical and cultural resources. Restoration of physical environment, old roads, architecture, gardens, streams, sceneries and Feng-shui tails is planned and existing Village museum is to be relocated to outside of the Village. A Detour road and buffering woods are also planned. As supporting facilities, Confucian cultural exhibition hall, a house for tasting Korean traditional cakes and a village courtyard are to be built. Suggested cultural programs to facilitate development of folklore culture are as follows: learning Feng-shui and field survey, host families for experiencing energy, ceremony restoration and chances of education for garden culture and classics, and festival for Korean traditional cakes.

위상 및 음압 레벨제어를 이용한 스테레오 음상 확대에 관한 연구

한찬호,박양우,장주석 경운대학교 산업기술연구소 2001 産業技術硏究論文誌 Vol.3 No.2(A)

Three-dimensional sound is a technique for generating or recreating sounds so they are perceived as emanating from locations in a three-dimensional space. Three dimensional sound has the potential of increasing the feeling of realism in music or movie soundtracks. Three-dimensional sound effects depend on psychoacoustic spectral and phase cues being presented in a reproduced signal. In this paper we propose an effective algorithm for the sound image expansion in television system using stereo image enhancement techniques. In this algorithm, a lower frequency band sound is expanded by phase control and a higher frequency band sound is expanded by cross-talk cancelation. Compared to the other techniques of three-dimensional sound, the proposed algorithm use only two speakers to enhance the sound image expansion, while maintaining the original sound characteristics.

산화아연계 무기질과 솔잎추출물 첨가에 의한 농산물 포장 필름의 광 및 미생물 열화능 개선

한신,나현정,강용구,박찬영 전남대학교 촉매연구소 2001 觸媒硏究 論文集 Vol.22 No.-

To invent environmentally friendly materials for packaging of agricultural produce, morphological and mechanical properly changes after daylight exposure and soil deposit for LDPE films composed of different incorporation substances have been investigated. Silver coated ceramic, zinc oxide, fine particle of ferrofluid and pine needle's extract were the incorporated substances. The pine needle's film degrades fast in soil while the silver coated ceramic's film shows daylight decay more on the morphological view. The mechanical strength keeps almost same. But turndown of elongation is explicit on the pine needle's film and silver coated ceramic's film.

Semantic Network을 이용한 자연 언어 추론 알고리즘

박찬곤,한성국 淸州大學校 1984 論文集 Vol.17 No.2

Semantic Network를 이용하여 자연언어의 추론 알고리즘을 유도하였다. 한국어의 Predicate와Argument의 관계를 조사의 표출 형태를 중심으로 격으로 분석하고 어미의 표현 형태로부터 논리적인 연결관계를 분석하였다. 격구조와 논리적인 연결관계에 기초한 Semantic Network를 정의하여 Pattern matching에 의한 추론 방법을 보였다. 본 알고리즘은 자연언어가 내포하고 있는 정보를 그대로 이용하고 있으므로 논리식의 변환 등이 불필요하며 규칙의 적용도 Pattern matching에 의하여 이루어지기 때문에 효과적임을 예를 통하여 보였다. In Korean Language, relationships between Predicates and Arguments are analyzied into case structures based on types of Particles and logical connective relationships from Verbal endings are also analyzied, Defining Semantic network with these relation ships, inference can be Performed using Pattern matching technique. As a derived algorithm in this Paper infers with the implied informations of natural language, it is more efficient in implementing and applying the concepts. To prove this, several well-known examples are treated.

DMPO-OH에 대한 전자 스핀 공명 연구

박영현,홍세용,한찬수 순천향대학교 기초과학연구소 1999 순천향자연과학연구 논문집 Vol.5 No.1

Electron spin resonance studies of the radical DMPO-OH induced by Fenton reaction have been carried out at room temperature. The ESR spectra have 4 hyperfine lines due to interactions with the nuclei of nitrogen and hydrogen at the position of βin the radical DMPO-OH. As results of our analysis, the ESR parameters have been found that ?? , the hyperfine coupling constants are well accord with those of Chamulitrat et al. and Akira Hamata but ?? that is reported on this paper.
