Neurofibromatosis, first described by von Recklinghausen in 1882, is a dominantly inherited mesodermal and ectodermal dysplasia with a broad spectrum of clinical findings. Most clinicians know that von Recklinghausens neurofibromatosis denotes more than the dermatologic curiosity of cafe-au-lait spots. In this disease, neurofibroma can be found everywhere in the body, but gastrointestinal neurofibroma associated with von Recklinghausens disease is infrequently reported. Patients with this disease may experienee gastrointestinal hemorrhage, small bowel obstruction, malignant degeneration of neurofibromas. Recently, the authors experienced a case of simultaneously developed gastric neurofibroma and leiomyoma in a patient with von Recklinghausens disease and associated literatures were reviewed.

To overcome the negative effects of too frequent feedback, researchers have explored several different schedules for reducing the frequency of augmented feedback, among them summary feedback, average feedback and bandwidth feedback. Summary feedback involves withholding feedback from subjects until the last trial in a block is completed, and then presenting feedback about each trial. A variation of this method called average feedback presents subject with only the means of the trial block. The bandwidth feedback refer to a range of correctness related to performance and is the type of feedback used "naturally" by those who provide augmented feedback to others(such as teachers and therapists). Summary feedback, average feedback and bandwidth feedback have similar effects on learning, and these schedules are more effective them every-trial feedback. During acquisition, the performance of the average, summary and bandwidth feedback generally was poorer the every-trial feedback. However if the take being learned is measured by performance on the retention tests, after any temporary effects of the feedback manipulations during practice have dissipated.

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 purpose of this study was to investigate where a feedback(self-controlled) schedule controlled by learner would be a more effective means of delivering feedback than any predetermined feedback schedule. Subjects(n=60) were randomly assigned to one of five conditions : Control condition, 50% relative frequency feedback condition, bandwidth feedback condition, self-controlled performance feedback condition, and yoked control condition. Experiment was designed to determine the optimal feedback condition for performance and learning of underhand toss. In experiments, subjects performed 50 acquisition and two retention trials blocks were analyzed with two experimental conditions to which they had been assigned. Data obtained from all subjects in five 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 5×5(condition ×trial block) analysis of variance(ANOVA) with repeated measures on the second factor. The retention trials were analyzed in a 5 ×2(condition ×trial block) analysis of variance with repeated measures on the second factor. Dependent measures were absolute error(AE), and variable error(VE). In conclusion, it should be stressed that the results of this study do support the guidance hypothesis of feedback and these findings showed that self-controlled subjects tend to produce improvements in the learning of underhand toss.

The purpose of this study was to investigate the effects of participation of the physical educational club on high school students' self-esteem and mental health improvement. The subjects for this study were 126 male students who were studying in an Electronic High-Tech High School. All of subjects were freshman. Subjects were divided into two groups. The experimental group was 63 male students who were acting in the Physical Educational Club, and the control group was 63 male students who did not join any student club. Pre-test was conducted on March when the school start, and post-test was completed on October(after 7 months). The statistical method was used paired t-test. The results of this investigation were as follow. 1. The experimental group who were participated in physical education club had more significantly positive improvement than control group on general self-esteem and social self-esteem. 2. The experimental group who were participated in physical education club had more positive effect than control group on the decrease of obsessive-compulsive, interpersonal sensitivity, depression, paranoid ideation, anxiety, phobic anxiety.

The purpose of this study was to analyze contextual interference in acquisition and retention of motor skill of children(9.2 year) by computer software(Charles H. Shea, 1993). Subject performed 54 trial with blocked practice and random practice in acquisition performance phase. Retention performance phase was measured after a 5-min and a day in random practice. The results are as follows : 1. In the acquisition performance phase, blocked practice condition had faster RT than random praction condition. 2. In retention performance phase, blocked practice condition and random practice condition revealed no significant difference.

In the early decades of this century, Charisma which originally means endowment with the gift of grace, has been introduced to social sciences by German sociologist, Max Weber. It quickly became interested in the field of sociology and politics. But, into the 1970s, charismatic leadership still had not became a subject for empirical or experimental research related to organizational theory. Recently, much attention has been paid to charismatic leadership as the prototype of leadership that people have in mind when they describe their ideal leader and is more likely to provide a role model with which subordinates want to identify. As a result, in will perform further study related to Charisma leadership which developing various kind of measurement and instrument. Finally, it should identify lost of possibility and phenomenon through the study of charisma leadership.
