Granular cell tumors (GCT) are rare tumors of neural origin involving mostly the tongue and skin. However, with the increased use of endoscopy, the gastrointestinal tract has been reported as a common location. the esophagus is the gastrointestinal site most frequently affected. Such tumors are rarely seen in the stomach, colon or rectum. It usually appears as a small, poorly circumscribed nodule with benign clinical course. Subsequently one case of a granular cell tumor of the ascending colon in 38 year-old female which were successfully diagnosed by a endoscopy and a endosonography and confirmed using snare polypectomy is here in reported.

Background/Aims: When determining the subsequent management after endoscopic resection of the early colon cancer (ECC), various factors including the margin status should be considered. This study assessed the subsequent management and outcomes of ECCs according to margin status. Methods: We examined the data of 223 ECCs treated by endoscopic mucosal resection (EMR) from 215 patients during 2004 to 2014, and all patients were followed-up at least for 2 years. Results: According to histological analyses, the margin statuses of all lesions after EMR were as follows: 138 cases (61.9%) were negative, 65 cases (29.1%) were positive for dysplastic cells on the resection margins, and 20 cases (8.9%) were uncertain. The decision regarding subsequent management was affected not only by pathologic outcomes but also by the endoscopist’s opinion on whether complete resection was obtained. Surgery was preferred if the lesion extended to the submucosa (odds ratio [OR], 25.46; 95% confidence interval [CI], 7.09–91.42), the endoscopic resection was presumed incomplete (OR, 15.55; 95% CI, 4.28–56.56), or the lymph system was invaded (OR, 13.69; 95% CI, 1.76–106.57). Fourteen patients (6.2%) had residual or recurrent malignancies at the site of the previous ECC resection and were significantly associated with presumed incomplete endoscopic resection (OR, 4.59; 95% CI, 1.21–17.39) and submucosal invasion (OR, 5.14; 95% CI, 1.18–22.34). Conclusions: Subsequent surgery was associated with submucosa invasion, lymphatic invasion, and cancer-positive margins. Presumed completeness of the resection may be helpful for guiding the subsequent management of patients who undergo endoscopic resection of ECC.

대한민국이 고령사회에 접어듦에 따라 관련 제품의 연구 및 개발이 많이 진행되고 있으나, 활동영역의 제약 및 리프트 장치 이용 시 불안정성 등 다양한 문제가 존재한다. 본 연구는 편안하고 안정적인 이동을 보장하기 위해 여러 가지 기구학적인 설계와 기계적 요소를 결합하여 호환 장치와 현가장치가 갖춰진 전동휠체어를 설계하였다. 또한, 리프트 사용 시 발생할 수 있는 전복 사고를 방지하기 위해 전복방지 장치를 추가로 구성하였다. 본 연구는 실버 세대의 활동 환경을 개선할 뿐만 아니라 추후 의료 등 다양한 분야에 활용할 수 있는 몇 가지 가능성을 제시하였다. As Korea enters an aging society, many studies of related products are being conducted. But there are various problems such as activity restrictions and instability using a lift. This study designed an electric wheelchair equipped with compatible devices and suspension devices by combining various kinematic designs and mechanical elements to ensure comfortable and stable movement. In addition, Overturning-device was additionally configured to prevent accidents that may occur using the lift. This study not only improves the activity environment of the user, but also presents several possibilities that can be used in various fields such as medical care in the future.

최근 과학예술융합교육(Science, Technology, Engineering, Art and Mathematics; STEAM)의 중요성이 증대되고 있으며, 로봇활용교육도 좋은 대안으로 고려되고 있다. 현재 대부분의 초등 로봇활용교육은 방과후교실로 운영되고 있는데, 주로 과학과 로봇에 관심이 많은 남학생들을 중심으로 이루어지고 있다. 본 논문에서는 먼저 초등학생들이 로봇을 활용하여 STEAM에 대한 흥미를 유발하게 되는지를 살펴보고자 하였다. 로봇활용의 범주를 5가지(추상적 이해형, 구조중심형, 운동중심형, 지능중심형, 가치지향형)로 나눈 후, 초등정규교육과정을 분석하여 적용 가능한 모든 교과와 단원을 추출하였다. 그리고 추출된 단원에 대하여 정규수업시간 내에 수행이 가능한 로봇을 활용하는 교안을 개발하고, 5개월간 적용하였다. 분석 결과, 로봇활용교육이 STEAM에 대한 흥미를 유의미하게 증진시키는 것으로 나타났으며, 특히 여학생의 경우가 더 두드러졌다. 이와 더불어서, 정규 수업에서 로봇활용교육을 운영하는 데 있어서 당면하게 되는 문제점들에 대해 논하고, 향후 STEAM을 위한 로봇활용교육과 관련한 제언을 제시하였다. 'Learning with a robot' is now considered as one of the best candidates for STEAM education, which is recently growing its importance. Most of the 'learning with a robot' programs in elementary schools serve as afterschool classes. The students participating in the afterschool classes are mostly boys who are interested in science and robots. This paper mainly concerns that a robot can be helpful for improving students' interest in STEAM education. We divided the robot utilizable aspects into 5 areas with educational points of view; abstract concept understanding type, structure-oriented type, athletics-oriented type, intelligence-oriented type and value-orientated type. We extracted all robot utilizable subjects and units from elementary school curriculum, and developed lesson plans which can be applicable to regular classes. And we also verified them by applying into an elementary school for 5 months. As the result of the analysis, we can conclude that 'learning with a robot' can encourage students' interest in STEAM, and it is more effective for girls than boys. Finally, we discuss problems that teachers may face in using a robot for regular classes, and make suggestions about the use of a robot for STEAM education.
