Student Selection Methods for Medical School and Progress after Admission Follow-up Study at Yamaguchi University. 3. Relation of Interview Evaluation and Progress after Admission / 医学教育

The relation between results of interview evaluation and progress after admission, especially the need to repeat years of school, dropping out, and results of the national examination for medical practitioners, was investigated in 318 students. Among students who had been admitted on the basis of open entrance examination, those who had lower interview evaluations needed to repeat a year of school at least three times more often than did other students. Among students who had been amitted on the basis of recommendations of high school principals, no such difference was observed, probably owing to selection bias. On the other hand, students who repeated a year of school had a significantly higher failure rate on the national examination for madical practitioners than did other students.

Student Selection Methods for Medical School and Progress after Admission. Follow-up Study at Yamaguchi University. 2 / 医学教育

The relation between student selection methods, including results of entrance examinations, and progress after admission was analyzed by means of path analysis and discriminant analysis in 318 sudents. Among students who had been admitted on the basis of an open entrance examination, those with rank in high school record from high school and female students performed better in medical school, whereas students who had prepared for the entrance examination after graduation from high school performed worse. On the other hand, students who had rank in high school record from high shool, who had higher interview evaluations, or who had earned a degree other than a medical degree were more likely to pass the national examination for medical practitioners after a minimum of 6 years of study. Among students who had been admitted on the recommendations of high shool principals, those with better grades during high school records and higher interview evaluations had a higher success rate on the national examination for medical practitioners.

Methods of Selecting Students for Medical School and Performance after Admission. Follow-up Study at Yamaguchi University. 1. Relation between Characteristics at Entrance Examination and Performance after Admission / 医学教育

A follow-up study of the relation between methods of selecting medical students and performance after admission was investigated. The subjects were 318 students who had entered our medical school from 1987 through 1989. Two hundred fiftynine students had passed open entrance examinations and 59 students had passed special examinations for those who had been recommended by their high school principals. We found that students who had earned a degree other than a medical degree had the best performance, as measured by academic records, promotion, and results of the national examination for medical practitioners. They were followed in descending order by students who had been admitted upon recommendations of high school principals, students who had passed open entrance examinations immediately after graduation from high school, students who had prepared for entrance examinations for 1 or 2 years after high school, and students who had prepared for 3 years or more.

An Experimental Study of F Wave Morphology

The characteristics of the surface recorded F responses including minimal latency, mean latency, amplitude, duration, area and shape were investigated in the posterior tibial nerves of rabbits. During a train of 100 stimuli, each F wave was divided by the recurrence of shape into repeaters and nonrepeaters. There was no significant difference between the parameters of repeaters and nonrepeaters such as mean latency, minimal latency, amplitude and area. These findings suggest that the associated discharges of motor neurons generating the repeaters of F wave represented no definite distinctions from that of nonrepeaters in the aspect of the neuron size or the number of neurons contributing to each parameters of F wave. After the sciatic nerve was exposed, it was minimally injured by compression and then F responses were studied. Mean latency and minimal latency were prolonged, and amplitude and area were diminished in post-injured group. The frequency of repeater waves was increased but was not a useful parameter in the assessment of injury model due to a wide range of normal value.
