The purpose of this study was to perform a kinematic analysis of the high jump techniques of the three men`s medalists at the 2011 IAAF Championships in Daegu (August 27-September 4, 2011), In particular, a three-dimensional coordinates method was used to analyze the last three strides before touchdown, the touchdown techniques, and the movements after takeoff toward the bar. An analysis of the, data for the biomechanical characteristics of the world`s best high jumpers could contribute to an improvement in the performance of a national high jumper. The first conclusion of the data analysis was that the arm movements of the gold medalist, J. Williams, had a single arm form, whereas the arm movements of the other medalists were a double arm form. Second, the difference in the knee joint angles upon touchdown and toe-off was 10˚. Third, J. Williams achieved his maximum CM height after takeoff (1.26m) using the maximum flexion of his knee joint. Fourth, the foot contact duration of A. Dmitrik (0.11 s) was the shortest among the medalists, and the ratio for his transformation of horizontal velocity to vertical velocity was the greatest (75.25%) among the three. Last, the maximum CM height of T. Barry was the greatest, and his foot contact duration was the longest.

In this paper, some problems that occur from faulty elements in a direction finding system composed of the linear array are studied and the method which improves the performance is proposed. The fault element means the sensor that has no output or highly reduced gain than other normal sensors. In the case of the presence of faulty elements, the performance of the conventional the spatial spectrum subject to a constraint. The corrected spatial spectrum is obtained by this vector. The computer simulations have been performed to study the performance of the proposed method. We have compared the proposed method with the subaperture processing method of one of the previous works. 이 논문에서는 선형 어레이로 구성된 방향 탐지 시스템에서 결함 소자가 발생하였을 경우 발생되는 문제점들을 제시하고, 시스템의 성능을 개선하기 위한 방법을 제안하였다. 여기서 결함 소자란 센서의 출력이 없거나 정상적으로 동작하는 센서에 비해 그 이득이 크게 감쇄되어 미세한 출력을 얻는 현상을 의미한다. 결함 소자 발생시에 기존의 방향 탐지 방법들의 성능은 크게 저하된다. 제안된 방법에서는 제한 조건을 만족하면서 공간 스펙트럼 값을 최대화하는 방향으로 보정 벡터값을 구하며, 이 보정 벡터를 이용하여 개선된 성능을 갖는 공간 스펙트럼을 얻는다. 제안된 방법의 성능을 고찰하기위해 컴퓨터 시뮬레이션을 수행하였으며 기존의 결함 소자 문제 해결 방법중의 하나인 부분 처리 방법과 비교하였다.

The sustained-release beads containing terbutaline sulfate (TBS) were prepared by rotogranulation method. The drug was dusted on the non-pareil seeds in a CF-granulator. The sustained-release beads were obtained by coating the active beads with ethylcellulose or $Eudragits^{(R)}$, using in any case the same granulator employed for active beads preparation. The release characteristics of sustained-release beads were examined in vitro by rotating basket method applied to $Bricanyl^{(R)}$ durules which is a sustained-release TBS matrix tablet. The release of terbutaline from the beads in vitro was first-order, and the release rate was dependent on both the coat weight ratio and membrane hydrophilicity. Both surfaces of the beads before and after dissolution were smooth. The drug release pattern from the beads could be thought the diffusion through the polymer membrane. The release rate and the surface of the beads stored for 3 years at room temperature were the same with those of the initial beads.

Steam reforming of methane using Xe-arc solar simulator was studied for the application of concentrated solar energy into chemical reaction. The reactor, a volumetric absorber, consisted of a porous ceramic foam disk coated with commercial reforming catalyst. Operating temperature was in the range of $450\;-\;550^{\circ}C$ and the excess steam ratio to methane was from 3.0 to 5.0. At the steady-state condition, the conversion of methane Increased with temperature in the range of 15 % - 30 % and the experimentally determined conversion was found to be close to theoretical equilibrium conversion. It was also found that the CO selectivity slightly decreased with excess steam ratio. Finally, the conversion of methane decreased significantly with space velocity of reactants.

Steam reforming of methane using Xe-arc solar simulator was studied for converting solar radiation into energy foam that one can readily utilize. The Xe-arc lamp produce a spectrum similar to that of the sun. SiC ceramic foam, resist high temp.(>900?C), is used to catalytically active foam absorber, and to support of reforming catalyst. The catalyst on the surface of foam were directly irradiated with solar simulated xe-light in order to carry out the steam reforming of methane. The reactor was made of stainless steel and quartz window was located on a place of the xe-light irradiation and temperature was controlled using K-type thermocouple in contact with catalyst located inside the reactor. The result show that a possibility of solar reforming using catalytically active foam absorber is exist.

디지털 시네마의 “프레임” 개념에 대한 연구

김기만 ( Ki Man Kim ) 부산대학교 영화연구소 2012 아시아영화연구 Vol.5 No.2

매체의 변화에서 기인한 새로운 예술발전 경향에 관한 논의들은 무엇보다도 예술의 전통적인 개념들의 반성을 불러일으킨다. 본 연구는 시네마에서 디지털 시네마로의 이행이 야기하는 개념들의 변화양상을 미학적 측면, 그 중에서도 프레임 개념의 변화를 중심으로 살펴본다. 디지털 시네마에서 프레임은 기존의 현실을 드러내는 것이 아니라 이미지 내부에 잠재되어 있는 디지털 알고리즘 형식을 현실화하는 것 이다. 디지털 시네마에서의 프레임은 앙드레 바쟁의 주장처럼 현실의 일부분을 드러내는 차폐물이 아니라, 디지털 이미지의 잠재성을 현실 화하는 표출(Expose)-프레임이다. 표출-프레임은 잠재적 코드를 가시화 하는 디지털 이미지가 현실화하는 것이다. 그것은 현실을 가려서 현실 의 일부분만을 보여주는 가림막이 아니라 디지털 이미지의 잠재성을 열어 펼치는 열림막이다. 외화면이 없는 디지털 프레임의 내부로 향하는 움직임은 그 자체로 잠재적 시간성을 나타낸다. 일상적 지각으로 파악하지 못하는 잠재적 시간성을 관객에게 보여주는 것이다. 디지털 시네마에서 프레임은 외부로 열려있지 않고 그 자체로 완벽한 내부를 이룬다. This study deals with the relationship of digital technology and aesthetics of digital cinema. The ways of reception of images are changed by modification of the media. And the concept and the discourse about the art have changed by the media. Digital technology penetrated into cinema than any other technological changes in the past and has been leading the shift in cinema`s concept and discourse. The frame in digital cinema does not represent things which exist in real world but actualizes the virtuality which is immanent in digital image. According to Andre Bazin opinion, the frame in film cinema is a cache which reveals some part of reality. But the frame in digital cinema is the ``Expose-Frame`` which actualizes the virtuality of digital image. Expose-frame visualizes the algorithm codes and actualizes the virtuality of digital image. It is not the cache which covers reality of real world and shows things what a part of Real, but the exposure space which exposes the virtuality of digital image. Theframe in digital cinema does not have the hors-champ. The digital cinema frame which does not have the hors-champ moves inside the image and this movement shows the virtuality time in itself.

이야기에 기초한 유아 집합교육 少考

김기만(Kim, Ki Man) 한국영재학회 1995 영재교육연구 Vol.5 No.2

The radical development of modern mathematics is due to the appearance of Collection Theory by George Cantor. The Set Theory is independent as an area and also closely interrelated with other areas. So its content becomes a common sense and a basic part across the whole area of modern mathematics. Accordingly, the basic element of modern mathematics is helping young children get familiar with set as early as possible. The thinking of set by which children can categorize, make partial sets and correspondences, understand the general characteristic, and conceptualize the discovered relationships is very important for young children. At this point where the Math education for young children is emphasized under the influence of the modernization movement of Math education, the systematic education for building up the set concept as the basic background of number concept during the early childhood is required. On current mathematics education for young children, graphs, the foundation of geometry, time, and patterns have been included in the traditional and practical content related to numbers. However, the education on collection which is the foundation of number concept is insufficient. A study shows that the level of young children's understanding on set is quite high, but the set concept isn't reflected in current Math curriculum for young children. And basic activities neccessary on building up the set concept, such as categorization, comparison, etc. are conducted in kindergardens but unsatisfactory because of those kindergarden teachers' premature understanding on the set concept. In conclusion, the curriculum for young children should be reorganized based on the set concept as the kernel concept. Also, the reappraisal of the training curriculum and the supplementary efucation for kindergarden teachers are urgent for raising the teaching ability of those kindergarden teachers.
