  • Purpose : Authors designed a customized Small Bowel Displacement System (SBDS) to displace the small bowel from the Pelvic radiation fields and minimize treatment-related bowel morbidities. Materials and Methods : From August 1995 to Mar 1996. 55 consecutive patients who received pelvic radiation therapy with the SBDS were included in this study. The SBDS consists of a customized styrofoam compression device which can displace the small bowel from the radiation fields and an individualized immobilization abdominal board for easy daily setup in prone position After opacifying the small bowel with Barium3, the patients were laid Prone and posterior-anterior (PA) and lateral (LAT) simulation films were taken with and without the SBDS. The areas of the small bowel included in the radiation fields with and without the SBDS were compared. Results : Using the SBDS, the mean small bowel area was reduced by $59\%;on\;PA\;and\;51\%$ on LAT films (P=0.0001). In six Patients (6/55. $11\%$), it was Possible that no small bowel was included within the treatment fields. The mean upward displacement of the most caudal small bowel was 4.8 cm using the SBDS. Only $15\%$ (8/55) of patients treated with the SBDS manifested diarrhea requiring medication. Conclusion : The SBDS is a novel method that can be used to displace the small bowel away from the treatment portal effectively and reduce the radiation therapy morbidities. Compliance with setup is excellent when the SBDS is used.

  • From 1990s the Ministry of Education and KERIS have developed nationwide academic resource sharing and service system based on universities, and have contributed to bridge the gap of information and to facilitate resource sharing between universities. Meanwhile, in Japan which starts 15 years earlier than us, the Ministry of Education and NII built nationwide academic resource sharing and service system with starting on the project of university holding resource sharing and until now have shown similar aspect of development like us. But lately, since information environment has been changing rapidly, Japan try to find new paradigm which goes around electronic resources management substitute for physical resources and open access based academic communication, institutional repository which disseminate university's research output to the outside world. This study compare academic resource sharing and service system between Japan and Korea and try to suggest for Korean academic resource sharing and service system development. In Korea, firstly we should try to replacing published resources management system to electronic resources', secondly, reorganizing oversea's resource sharing and service system, thirdly, reactivating institutional repository toward open access, finally, unification of distracted driving force.

  • Human organs in the body have a complex structure, and in particular, the small intestine is about 7m long, so endoscopy is not easy and the risk of endoscopy is high. Currently, the test is performed with a capsule endoscope, and the test time is very long. The doctor connects the removed storage device to the computer to store the patient's capsule endoscope image and reads it using a program, but the capsule endoscope test results in a long image length, which takes a lot of time to read. In addition, in the case of the small intestine, there are many curves due to villi, so the occlusion area or light and shade of the image are clearly visible during the examination, and there may be cases where lesions and abnormal signs are missed during the examination. In this paper, we provide a method of assisting small intestine capsule endoscopic lesion examination using artificial neural networks to shorten the doctor's image reading time and improve diagnostic reliability.
