본 연구는 실업계 고등학교 컴퓨터교육에서 협동학습방법의 적용 가능성을 검증하기 위해 협동학습 교수 학습 지도안을 설계하여 실험집단에 적용한 후, 전통학습을 적용한 통제집단과의 학습동기와 학습성취도 효과를 비교 분석하여 실업계 고등학교 컴퓨터교육에 바람직한 교수 학습방법을 마련하고 학생중심 교육과정에 알맞은 학습구조를 제안하는데 목적이 있다. 연구의 결과, 협동학습 프로그램을 적용한 실험집단이 학습동기 및 학습성취도에 대한 평균점수의 검증결과 가장 높게 나타났으며, 통계적으로도 p<.001 수준에서 유의미한 것으로 나타났다. The purpose of this paper is to compare and analyze on the result of academic motivation and achievement between two groups in order to certify the application possibility of the cooperative learning method in computer education, and on these research results this paper is to propose the profitable learning and teaching method to the teachers in the class of the computer department and to contribute the improvement of the academic motivation and achievement in computer education of the vocational high school's students. As a result, the post-test average score of academic motivation and achievement in experimental group appeared to be significantly higher than that of the comparative group. And that result is accepted as statistical in significance level p<.001

Hyalinizing trabecular tumor (HTT), a type of thyroid lesion, was first reported by Carney in 1987 and has since been reported continuously. Due to its histological non-specificity, HTT can be misdiagnosed as papillary thyroid cancer or medullary thyroid cancer. For this reason, over treatment might occur; for example, total thyroidectomy and lymphade-nectomy. Diagnosis and treatment is a challenge because there is still controversy regarding HTT characters. We report on two cases. One patient was a 48-year-old female and the other was a 46-year-old female. Both patients complained of a thyroid mass and were diagnosed as HTT.

Purpose: The aim of this study was to investigate the risk factors of reflux associated complications (reflux symptoms, reflux esophagitis, and esophageal stricture) after gastrectomy for proximal gastric cancer. Methods: 150 patients with proximal gastric cancer were included from January 2005 to December 2008. Their medical and surgical records were retrospectively analyzed concerning clinical and pathologic characteristics, operation methods, morbidity, reflux associated complications and nutritional states. Results: Tumor sizes and operation methods were statistically significant in univariate analysis of risk factors for reflux associated complications (P<0.05). However, only operation methods were statistically significant in multivariate analysis (P=0.00). We, thus, compared operation methods. There were no significant differences in morbidity, body weight, hemoglobin, serum cholesterol, protein and albumin between total gastrectomy groups and proximal gastrectomy groups (P>0.05). However, reflux complications were significantly more common in proximal gastrectomy groups (72.4%) than in total gastrectomy groups (29.5%). Severe reflux esophagitis (LA classification C or D) was found in only proximal gastrectomy groups. Conclusion: Total gastrectomy is favorable for proximal early gastric cancer in terms of reduced esophageal reflux complications.
