The purpose of this study was to investigate where a feedback schedule controlled by learner would be a more effective means of delivering feedback than any predetermined feedback schedules. Subjects were randomly assigned to one of three conditions : control condition(n=12), yoked condition(n=12) and experimental condition(n=12). Data obtained from all subjects in four acquisition and two retention trials blocks were analyzed with two separate analyses of variance for each of four error scores. Analysis performed on the acquisition trials were a 3×4(condition ×trial block) analysis of variance (ANOVA) with repeated measures on the second factor. The retention trials were a 3×2(condition ×trial block) analysis of variance (ANOVA) with repeated measures on the second factor. Dependent measures were absolute error, variable error, radial error and directional angle error. Analysis on the experiment indicated a significant main effect for the trial blocks during retention phase. The variable error in the retention phase revealed that the second block performed significantly better consistency than the frist block.

The purpose of this study was to investigate the effect of physical education preferences on physical education classes content, motor skill, exercise environment, and pleasure derived from physical activity factors in Korea and Japan elementary students. The results of this study are as followed. Firstly, with regard to physical education classes content preferences of comparison between nation·sex, the like group of Korean and Japanese has significantly high preference than that of the neither and dislike group in gymnastics, track & field, swim and ball game. Comparison between like group, Japanese male and Female students showed significantly high than that of the korean male and female students in gymnastics, track & field, swim. Secondly, with regard to motor skill of comparison between nation·sex, the Korean group higher than that of the Japanese group in ‘mat rolling back’, ‘wall upside down’ and twirl hula hoop’, and the Japanese group has higher than that of the Korean group in ‘can do’ of ‘iron bar kick up’, ‘soccer ball lifting’, and ‘25m swim’. Third, with regard to exercise environment of comparison between nation·sex, the like group of Korean and Japanese has higher than that of the neither and dislike group in ‘exercise confidence’, ‘thank you teacher’, and ‘low grade sports play’. But the dislike and neither group has higher than that of the like group in ‘exercise useless work’, and ‘exercise shame’. Lastly, with regard to pleasure derived from physical activity factors of comparison between nation·sex, the like group of Korean and Japanese has significantly higher than that of the neither and dislike group in factor 1, factor 2 and factor 3.

본 연구에서는 생성적 적대 신경망(GAN; Generative Adversarial Network)기반의 딥러닝 모델을 이용하여 라이다 반사강도 데이터의 자연칼라 영상화를 수행하였다. 반사강도 데이터는 능동센서인 레이저 스캐너에 의해 근적외선 파장대에서 획득되므로 광학영상과 비교하면 물리적, 광학적, 해상도, 품질, 패턴 등 여러 측면에서 다른 특성을 가지고 있다. 특히 라이다 데이터는 중심투영의 광학영상과 다르게 정사투영에 의해 획득되고, 폐색영역과 그림자 영향이 없으므로, 라이다 반사강도 데이터를 딥러닝에 의해 고품질의 자연칼라로 영상화하면 엄밀정사영상을 효율적이고 획기적으로 생성할 수 있는 방법이라고 판단된다.

The prupose of this study was to analyze the effect of precue on a event uncertainty of information processing for movement execution. Subjects(n=33) was randomly assigned to control and experimental condition. The experimental group performed reaction time tasks with the different precue condition but control group performed only same number of stimulus-response alternatives. Data obtained from all subjects were analyzed with two separate analyses of variance. By experimenting the groups and the precue condition, there was a significant difference by showing p<.001 a significant level for groups, p<.001 a significant level for precue conditions. And the group precue phase revealed that the experimental group; performed significantly faster than control group on the precue 1 and precue 2. In conclusion, a precue is advance information that recuces the amount of processing required and this reduces reaction time as well. And a precue may functionally reduce the number of alternative that must be considered.

The aim of this study was to investigate how the simple stimuli-response (1-choice) and the choice stimuli-response (2-choice, 4-choice) make an influence on Reaction Time (RT) of the Athletes. Subjects were 8 Athletes (Archery : 4, Soft tennis : 4). Lab Activities Manual with Software were used as an experimental device. Thirty reaction time trials will be administered. On each trial, four circles will be presented on the computer monitor.The subject task is to depress the appropriate key (DFJK) as quickly as possible when the stimuli is illuminated. The experimental data were analysied by Regression and Paired t-test through SPSS/PC+. The experimental results were as followed. The RT increaces by nearly an equal amount each time the number of alternative is doubled(1 to 2 to 4). The relationship between the choice RT and the Logarithm to the base two of the number of stimulus alternative should be so linear. The RT values of Soft-tennis ball group are shown on the faster on the choice stimuli-response than Archery group(P<.05).
