이족보행로봇을 위한 에너지 소비 관점에서의 고효율 걸음걸이 알고리즘 구현

조병훈,김대원 명지대학교 대학원 1999 대학원논문집 Vol.3 No.-

This paper presents a high-efficient gaital algorithm for a biped robot in the energy consumption point of view. The algorithm minimizes the torque of ankle joint and hip joint by using a window search method and a genetic algorithm with regard to the energy consumption. We find the relationship between energy consumption and stable margin according to the variation of the stable margin. As a result of simulation, it is known that increases of the stable margin induce increases of the energy consumption. Also, we find a minimum size of supporting surface when we can compensate for the ZMP by trunk motions. The fitness function of the genetic algorithm is used to minimize the energy of the biped robot. In case of the various supporting surfaces, we can find the most efficient weighting values of fitness function and thus we can increase the efficiency in the energy consumption point of view.

산업, 의용, 교통, 사회의 각 분야에서 응용되고 있는 공업용 텔레비젼(ITV)을 사용하여 동영상의 실시간 자동처리방법에 의한 고속도로상의 교통류를 계측하는 시스템과 그 알고리즘을 개발하였다. 영상계측 시스템에서는 ITV에 의한 실시간 처리를 가능하게 하기 위하여 VISC를 설계하여 그 유효성을 증명하였고, 그 시스템을 이용하여 각종 동영상의 처리 알고리즘을 개발하였다. 실제로 ITV 영상을 이용하여 고속도로상에서 도로의 횡단방향에 하나의 샘플점열을 설치하고, 1레인당 7점정도의 밀도로 샘플점열을 배치하여 계측알고리즘을 표시하고, 실험예에서는 계측 오차가 1∼2%의 정확도로 계측되는 결과를 표시하였다. This paper describes system and its algorithm which can measure traffic flow on the road, using industrial television applied in industry, medicine, traffic and society, by real-time processing of dynamic scene. We have proved its validity by designing VISC(Video information Sampler and Converter) and developed processing algorithm of dynamic scene by use of its system. In practice, a sample point is allocated in cross-direction. With the results, we have represented accuracy of this algorithm.

Considerable interest has been recently generated by the preparation of large monodisperse polymer particles by dispersion polymerization. In a dispersion polymerization process, the reaction mixture starts out as a homogeneous solution and the resulting polymer precipitates as spherical particles. The present study focused on dispersion polymerization of Ethly Methacrylate in water-ethanol mixture with a Azo initiator and a polymer stabilizer, poly(vinyl pyrrolidone) with an anionic costabilizer, Aerosol MA. Effects of polymerization parameters, such as monomer concentration, initiator concentration, stabilizer concentration, different molecular weight of stabilizer, comonomer concentration, and polymerization temperature on average particle size and size distribution have been investigated. The polymerization recipe of preparation of uniform PEMA particles in 2-6 ㎛ size range has been also made.

인간은 거의 아무런 노력없이 얼굴을 확인한다. 그렇지만 이러한 작업을 수행하는 자동시스템을 구현하는 일은 무척 어렵다. 얼굴 인식을 수행하는 시스템은 범인확인, 보안시스템, 그리고 화상전화등 여러분야에 응용될 것이다. 본 연구에서는 얼굴 인식에 부과되는 기본적인 문제들을 검토하였다. 이 문제들로는 얼굴의 표현, 얼굴의 검출, 얼굴의 확인 그리고 얼굴 표정의 해석등을 들 수 있다. 또한 얼굴 인식에 사용되는 특징 추출 알고리즘을 제안하였고 이 알고리즘에서는 얼굴의 특징점을 추출하기 위하여 피드백 메카니즘을 사용하였다. Humans identify faces with little or no effort. However, building an automated system that accomplishes this task is difficult. A system that performs face recognition will be adapted to many applications, for example, criminal identification, authentication in secure system, and videophone, etc. In this study fundamental problems of face recognition is discussed. These are as follows; representation of face, face detection, face identification, and analysis of facial expressions. Also, feature extraction algorithm for face recognition is proposed. In this algorithm the feedback mechanism is used. It is applied to identification system by using the result of this survey.

The mass treatment trial of pyrantel pamoate on Ascaris lumbricoides and Ancylostoma duodenale infections was carried out to school-children and inhabitants in rural areas in the central part of Korea. Pyrantel pamoate ("Combantrin") tablet (123 mg base) was administered as a single dose of 10. 0 mg per kg. body weight to a total of 4,198 Ascaris infected cases selected out of 4,436 (41. 6%) positives, who were screened from the total 10,660 collected stool specimens. Of these, only 3,169. cases were followed up after treatment to provide an analysis in this study. Incidentally 161 cases with concomittently infected hookworm were also subjected to assess the efficacy of pyrantel pamoate against A. duodenale. The egg negative conversion rate on A. lumbricoides was 95.3%, and on A. duodenale, 97.5% four weeks following treatment. In failed cases, the egg reduction rates on both of the infections were 97.6% and 97.3% respectively. No side effects and no problem in drug administration were demonstrated. It is concluded that this study confirms the high efficacy of pyrantel pamoate in the treatment of Ascaris lumbricoides and Ancylostoma duodenale infections and also proves the acceptability and safety of this drug in the mass treatment of ascariasis in a population with relatively high worm burden.

In industrial areas where noise level and the worker exposure time exceed the criteria, and evaluation should be made to determine the most economical solution to the problem. A large reduction in noise can be achieved by complete enclosure of a noise source. This study was carried out to determine the effect of Korean-made materials in noise reduction. A blower producing noise level of 91 dBA was used as a noise source, and plywood having surface density of 9.5 kg/㎥ and thickness of 1.8cm was used as sound-isolating partition and glass fivers of various densities and thicknesses were used as sound absorbing materials. Noise reduction effect of total and partial enclosures was evaluated. The results are summarized as follows. 1. When the blower was enclosed with and unlined enclosure constructed by plywood, the noise reductions by total and partial enclosures were 17㏈ and 9㏈ respectively at A-weighted measurements, which indicated lower effectiveness than the theoretical effect of the plywood. This could be resulted from the reverberant buildup in the enclosure. 2. To reduce the reverberation, glass fibers of various densites and thicknesses were covered inside the wall of enclosure and the effectiveness was as follow. 1) Noise reductions by plywood plus glass fibers having densities of 25-48 kg/㎥ and density of 100kg/㎥ were 20-25㏈ and 30㏈ respectively. 2) Noise reductions at 4,000 Hz by plywood plus 48kg/㎥ glass fibers having thicknesses of 2.5cm and 5.0cm were 31 and 41㏈ respectively. By doubling the thickness of glass fibers the noise reduction increased by 5㏈ at A-weighting. 3) The difference in noise reduction between total and partial enclosure was ranged from 5㏈ to 11㏈ at A-weighting. The higher the density of glass fibers were, the difference increased.

전통음악 이해의 양면성 : 한국음악 영문교재 개발을 위한 제언

이병원 이화여자대학교 한국문화연구원 2007 한국문화연구 Vol.13 No.-

이 글의 목적은 한국의 전통음악을 서양에 효과적으로 소개·보급하기 위한 방법을 제시하는 데 있다. 서양에서 한국음악을 강의하거나 연구하는사람들의 공통적인 불만은 그들이 쉽게 이해할 만한 개론서가 없다는 것이다. 근래에 들어서 한국의 사립대학과 정부 관련 연구기관에서 외국인을 위한 음악·문화·예술 자료를 출판할 계획을 가지고 있어 이러한 불만은 점차 해소되고 있다. 한국음악 영문교재 개발을 위해서 염두에 두어야 할 점은, 첫째 대상문화권마다 다른 접근 방법과 어법이 필요하다는 점이다. 둘째 교재 보급 대상에 따라 내용을 선택적으로 서술하는 것이 필요하다. 셋째 서양음악과 한국음악양쪽에 지식을 가진 학자가 교재를 집필하는 것이 중요하다. 넷째 현지인의 어법으로 전달할 수 있는 내용으로 구성해야 한다. 이러한 점에 유의하여 한국음악 영문교재를 개발한다면 한국음악의 국제화에 크게 기여할 수 있을 것이다. The aim of this article is to suggest the methods to introduce and propagateKorean traditional music efficiently to the West. People who teach and studyKorean music in the West often complain about the lack of an introductorybook which is easy to understand. Recently this kind of shortcoming is graduallybeing tended to, with the government research institutions and privateuniversities that plan to publish music, culture and art materials for foreigners. There are certain things to keep in mind when devising a Korean musictextbook in the English language: first, every target culture needs a differentapproach and wording. Second, the contents should be selectively described,according to different target readers of the textbook. Third, the author of thetextbook should have full knowledge of both Korean and western music. Fourth,the textbook should consist of contents that are communicable to the targetlocals. With attention on the points made above, the development of a textbookon Korean music in English will greatly contribute towards theinternationalization of Korean music.

This study was undertaken to analysis the forward pike somersaulting in 3m spring board diving with cinematographic method & to suggest quantifying material for performance in spring board diving. The subjects participated in the experiment were consisted of male athlete(2) & female(2) representing CheJu Do. The conclusions obtained were as follows; 1. In temporal analysis, elapsed time in air-phases was the longer, and factors influencing significantly in spring board was consisdered to be touch-down, take-off position, velocity. 2. In vertial & horizontal velocity components, factors influencing significantly in spring board was considered to be horizontal & vertical velocity at the release instant, the number of rotation, touch-down, and take-off position, therefore it was important factors absolutely distributing to horizontal & vertical components. 3. In angular displacement, as the number of rotation, the relative angle between thigh and trunk was higher. therefore it was necessary to decrease moment of inertia for more rotation. 4. In angular velocity, it as thought that Succession in the air-phase depend upon the touch-down in board & initial condition, decrease of moment of inertia according to increase of rotation in release in board. 5. In total angular momentum, The more stable variation in function of time, The more stable angular momentum was, the more deviation of it, the more unstable performance was. 6. Angular momentum of body segments from release on board to max. height was showed little relatively in constraint to entering, larger contribution of relative angular momentum. 7. There was a difference of kinetic variables among each rotations but common conclusions was needed to more short, instantaneous vertical component, less vertical angle, larger depression of board, larger local angular momentum. in 3m spring board.
