Subgroups of sperm which share similar motility features documented in mammals indicate between-subject variations that might be related to fertilizing potential of the respective ejaculates. The objectives of this study were to define subpopulations of motile sperm in Gyr falcon semen using kinematic parameters driven by Computer Assisted Semen Analysis (CASA) and to investigate the subjectrelated variations in these subpopulations. A total of 24 fresh ejaculates from 6 falcons were used to assign each of the 20473 sperms into 3 subpopulations by a multivariate cluster analysis. The proportion of sperms in different sub-populations were compared among subjects by a generalized linear model and repeatability of sperm frequency in different subpopulations was investigated by corelation analysis. The resulting 3 categories of sperm indicated significant differences in all kinematic parameters (p < 0.05). Subpopulation 1 (15.91%) contained sperms with the highest velocity and progressiveness of movement trajectory while subpopulation 3 (6.4%) included the least progressively motile sperms. Proportion of rapid and medium progressive sperm were consistently higher in the ejaculate of three falcons compared to the two other birds which also had the highest proportion of slow non-progressive sperms (p < 0.05). Respective proportion of sperms in each subpopulations indicated significant repeatability over multiple measurements (p < 0.05). In conclusion, subpopulations of motile sperm in Gyr falcon can be identified using kinematic parameters generated by CASA. Individual differences in the proportion of these subpopulations might have potential application for identifying the males with higher fertilizing capacity.

In 450mm wafers production environment for next generation Fab, one of the most significant features is the adoption of full automation to the whole manufacturing processes involved. The full automation system will prevent the workers from intervening the manufacturing processes as much as possible and increase the importance of each individual wafer noticeably, and thus require a more robust scheduling system for entire semiconductor manufacturing processes. The scheduling system for 450mm wafers production also should be capable of monitoring the status of each individual wafer and collecting useful Fab data in real time. In this study, we first analysis of cluster tool in 450mm wafers production environment, and then propose a real-time scheduling algorithm based on timetabling algorithm.

본 연구는 두 지역의 초등학교 창의적 체험활동 편성·운영의 사례 분석을 통해 문제점을 밝히고 이를 개선하기 위해 창의적 체험활동과 교과 교육과정의 연계 도구로서 내러티브의 적용 가능성을 탐구하는 데 목적이 있다. 연구의 결과, 교육과정 개발과 수업의 측면에서 내러티브의 적용 가능성을 제안하였 다. 첫째, 교육과정 개발의 측면에서 내러티브는 교과와 창의적 체험활동을 통합하는 매개체로 작용할 수 있다. 둘째, 수업의 측면에서 내러티브는 수업의 소재와 내용, 내용 전달 방식, 학습 공동체 형성의 도구로 작용될 수 있다. 마지막으로 창의적 체험활동의 네 가지 영역별로 내러티브 적용 방안을 제안하였다. 창의적 체험활동 편성·운영 시 내러티브를 활용하여 교과와 연계한다면 창의적 체험활동의 진정한 목표를 달성하는데 유용할 것으로 기대한다.
