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.

김기만,김영일,홍순억,Kim, Ki Man,Kim, Young Il,Hong, Soon Uk Korean College Of Clinical Pharmacy 1991 한국임상약학회지 Vol.1 No.1

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.

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.

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.

비윤리적 친조This study aimed to shed light on the generative mechanism and mediating mechanism of Unethical Pro-organizational Behavior (UPB) in the banking sector. To this end, we tried to empirically test the direct effect of the perceived Bottom-Line Mentality (BLM) on moral disengagement and UPB respsectively. Further, the study examined the mediating role of moral disengagement between the perceived BLM and UPB and the moderating role of the perceived leader integrity capacity between the perceived BLM and moral disengagement. As a quantitative study, a questionnaire survey method was used. Our respondents consisted of regular employees below the level of team managers and branch managers in bank branches. Using the final 438 respondents of the survey data, the empirical tests were conducted by using SPSS 25. The findings were as followed; first, the perceived BLM was significantly affected moral disengagement and UPB respectively. Second, moral disengagement positively mediated the relationship between perceived BLM and UPB. Third, contrary to our expectation, the perceived leader integrity capacity positively moderated the association between the perceived BLM and moral disengagement. In the conclusive part, this study summarized research findings, theoretical and practical implications, limitations of the research, and future research tasks.직 행동, 실적 중시 분위기, 도덕적 이탈, 상사의 도덕적 역량, 특성활성화 이론 본 연구는 국내 은행업 종사자들을 대상으로 비윤리적 친조직 행동에 미치는 선행요인에 관한 연구를 통해 비윤리적 친조직 행동의 발생 및 조절기제를 분석하고자 한다. 이를 위해 인지된 실적 중시 분위기가 도덕적 이탈, 비윤리적 친조직 행동에 미치는 직접효과와 도덕적 이탈의 인지된 실적 중시 분위기와 비윤리적 친조직 행동 간의 매개효과, 상사의 도덕적 역량의 인지된 실적 중시 분위기와 도덕적 이탈 간의 조절효과를 실증적으로 검증하고자 하였다. 본 연구를 위해 국내 은행 영업점에 종사하는 팀장·부지점장급 이하 정규직원을 대상으로 설문조사를 진행하였다. 최종 438부의 설문자료를 바탕으로 SPSS 25를 활용하여 실증분석하였다. 분석결과, 첫째, 인지된 실적 중시 분위기는 도덕적 이탈, 비윤리적 친조직 행동에 대해 정(+)의 방향으로 유의하였다. 둘째, 도덕적 이탈은 인지된 실적 중시 분위기와 비윤리적 친조직 행동 간의 관계를 정(+)의 방향으로 매개하였다. 셋째, 가설과 달리, 상사의 도덕적 역량은 인지된 실적 중시 분위기와 비윤리적 친조직 행동 간의 관계를 정(+)의 방향으로 조절하였다. 결론에서는 연구결과 요약과 연구의 의의와 시사점, 한계점과 향후 연구과제를 제시하였다.

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.
