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.2

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.

외이도 냉자극이 백서 중이점막의 혈관투과성에 미치는 영향

박찬일,고필준,이민한 충남대학교 의과대학 지역사회의학연구소 1995 충남의대잡지 Vol.22 No.2

The increased vascular permeability is first sign of inflammation and one of the early major sign in otitis media with effusion. The vascular permeability of the tympanic mucosa was observed after stimulation with cold water through the external auditory canal of rats and injection of Monastral blue, using whole mount preparations. Many monastral blue labelled vessels were noted in the pars flaccida and the tympanic mucosa near the office of eustachian tube but not in the pars tensa. The results suggest that cold stream stimulation through the external auditory canal could increase the vascular permeability in the middle ear mucosa of rats and that might be used an animal model to study early pathogenesis of otitis media with effusion.

cis-Jasmone의 합성에 관한 연구

박찬흥,오원택,김정한 연세대학교 산업기술연구소 1989 논문집 Vol.21 No.2

A practical synthesis of cis-jasmone (9) from readily available levulinic, acid was described. Levulinic acid ethylene dithioacetal (3) was reacted with 2-mercaptopyridine in the presence of DCC and DMAP in dichloromethane to give S-(2-pyridyl)-4-ethylenedithiopentanethioate (4) in excellent yield. The compound (4) was then allowed to react with cis-3-hexenyl Grignard reagent to produce cis-undec-8-ene-2,5-dione monoethylenedithioacetal (7) in very high yield. Compound (7) when treated with CuCl₂/CuO in acetone afforded cis-undec-8-ene-2,5-dione (8) which was then cyclized under basic condition (NaOH/H₂O, ??) to cis-Jasmone (9) in 81% yield. Thus a very important fragrance compound cis-Jasmone was synthesized from levulinic acid by 5 steps in 63% overall yield.

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.

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.

고무질 보강 식품포장용 LDPE필름의 기계적 강도와 기체투과 선택성

한신,강용구,박찬영 전남대학교 촉매연구소 2000 觸媒硏究 論文集 Vol.21 No.-

To improve the mechanical strength of the functional LDPE packaging film that has deficiency in the strength, though the film is active in vitality and has selective permeability for specific gases such as ethylene and carbon dioxide, this work blends a rubbery polymer, ethylene propylene monomeric rubber(EPM), in the LDPE film, and examines the mechanical strength and the permeability to assess preserving the functionality of freshness keeping of product. Overcoming the defect of incomplete coupling of the ceramic powder to the LDPE film is to use a coupling agent KBM-503( γ -methacryloxy propyl trimethoxy silane) of Shinetsu company in Japan. The optimum blending ratio of the EPM was about 5 percent in weight. The blended film reserves the selective gas permeability in relatively equivalent capacity of the non-rubbery film. The 5 percent EPM blended film has stronger mechanical strength than that made without the EPM, The strength approaches to the pure LDPE film. In conclusion, this work presents the method of improving mechanical strength without any depression in its freshness keeping functionality of the conventional packaging film.

닭실마을의 경관복원과 정비에 관한 연구

박찬용,김한배,황상돈 한국정원학회 2002 한국전통조경학회지 Vol.20 No.4

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.
