To investigate the acute effects of hemodialysis on the left ventricular function of dialysis patients, M-mode and Doppler echocardiographic studies were performed in 17 patients undergoing maintenance hemodialysis using acetate buffered dialysis solution. The results were as follows: 1) Blood urea nitrogen, creatinine, potassium, body weight, left ventricular end diastolic volume, left ventricular end systolic volume, sroke volume and cardiac index showed significant decreases after hemodialysis. 2) There was no change in sodium, heart rate, ejection fraction and fractional shortening. 3) Peak E velocity and peak A velocity were decreased significantly after hemodialysis and the E/A ratio was increased significantly. In conclusion, hemodialysis improves the left ventricular diastolic function in patients with chronic renal failure, and Doppler echocardiography is one of the useful tools for non-invasive and repeated evaluation of left ventricular diastolic function.

Ectopic or heterotopic pancreas is a developmental anomaly, Since the first gross description of heterotopic pancreas in the gastrointestinal tract by Schultz in 1727 and the first histologic descrip- tion of this phenomenon by Klob in 1859, intermittent resports have appeared in the literature adequately reviewing the clinical, radiologic, endoscopic and surgical aspects of this lesion. Reported here is a case of heterotopic pancreas of the stomach by gastrofiberscopic examination. A 65-year-old woman visited in April, 1989 to this hospital for evaluation and treatment of postprandial substernal pain and epigastric discomfortness for 10 days. Gastrofiberscopy revealed a 6 >< 7 cm sized protruding mass along the posterior wall on mid-body of stomach. It's center appeared an umbilical shaped dimple with a relatively normal mucosa. Biopsy showed a nest of pancreatic acini. Symptoms relieved after soft diet and now we follow up the patient at O.P.D.

본 연구는 교사의 셀프리더십이 창의적역할에 미치는 영향과 임파워먼트 조절효과에 대해 알아보고자 하는 데 그 목적이 있다. 이를 위하여 본 연구에서는 선행연구에 대한 검토를 통하여 3개의 변인을 도출하고 서울, 경기, 인천 지역의 중등학교 교사를 대상으로 설문조사를 실시하였다. 배부된 설문지 215부 중 200부가 회수되었으며, 회수된 설문은 SPSS 21.0 프로그램을 이용하여 통계분석을 실시하였다. 분석한 결과, 셀프리더십과 창의적역할에서 임파워먼트가 영향을 미치는 것으로 나타났다. 따라서 교사의 셀프리더십이 높을수록 창의적역할에 영향을 미치는 요인임을 알 수 있었다. 교사의 창의적역할을 위한 연수, 교사교육 프로그램 개발 시 임파워먼트와 셀프리더십을 신장시킬 수 있는 내용과 방법을 강구해야 할 필요가 있음을 시사한다. 본 연구 결과를 바탕으로 향후 교사의 셀프리더십에 대한 심도 있는 연구를 기대해 본다. The purpose of this study is to investigate the influence of teachers’ self-leadership on their creative roles and the effect of controlling their empowerment. To this end, in this study, three variables were derived through a review of previous studies, and a survey was conducted targeting secondary school teachers in Seoul, Gyeonggi, and Incheon. 200 of the distributed questionnaires were recovered, and the recovered the collected questionnaires were statistically analyzed using the SPSS 21.0 program. As a result of the analysis, it was found that empowerment had an effect on self-leadership and creative roles. Therefore, it was found that the higher the self-leadership of the teacher, the more influential the creative role. Training for the creative role of teachers. This suggests that it is necessary to devise contents and methods that can enhance empowerment and self-leadership when developing teacher education programs. Based on the results of this study, I expect an in-depth study on self-leadership of teachers in the future.
