The purpose of the present study is to examine effectiveness of self-controlled practice (USC and LSC) using a baseball throwing task. Specifically, the study examined the effects of practice with autonomy support on learners’ self-efficacy. Among 48 participants, 12 students were randomly assigned per group according to the exercise conditions. Participants practiced throwing with their non-dominant arm for target. Each experimental design of acquisition phase was 4 (group)×6 (block), retention and transfer tests were 4 (group)×2 (block), and self-efficacy was 4 (group)×3 (time) factorial design. Two-way ANOVA with repeated measure on blocks were conducted. Performance and self-efficacy scores were used for independent variables. In delayed retention and transfer test, USC (unlimited self-control) group was more effective than UY (unlimited yoke) and LY (limited yoke) groups. There was no difference between SLC (limited self-control) and LY groups. In addition, self-efficacy measured after practice and before delayed retention was increased in USC group and partially in LSC group. The findings indicate that the autonomy provided by self-controlled practice can raise learners’ self-efficacy, with effective consequences on motor learning.

Pyoderma gangrenosum (PG) is an inflammatory ulcerative condition of unclear etiology. In more than 50% of cases, lesions occur in association with an underlying systemic disorder-most notably; inflammatory bowel disease (IBD), rheumatoid arthritis, or a hematologic abnormality. Here, we report a rare case of pyoderma gangrenosum associated with autoimmune chronic active hepatitis. A 34-year-old woman presented pyoderma gangrenosum and an appropriate exclusion was performed. She had abnormal results for liver biochemical tests, with a hepatitis-like picture and high titer of antinuclear antibodies. According to the scoring system proposed by the Intemational Autoimmune Hepatitis Group she had `definite` autoimmune hepatitis and responded well to immunesuppressive treatment.
