Histogram-based methods have been used generally for retrieving an image to be searched in the video database. In this paper, we present an algorithm to retrieve an image incorporating the HVS. Comparing the performance of the previous algorithm with that of the proposed one, the new and better algorithm is proposed than the previous algorithm.

For the study of the hemodynamic changes of the cranial pancreaticoduodenal arterial flow(cPDAF) in the dog with acute pancreatitis, acute pancreatitis was experimentally induced in 10 dogs by the injection of oleic acid into the accessory pancreatic duct. The parameters of cPDAF were measured by transcutaneous pulsed-wave Doppler ultrasonography. The hemodynamic changes included resistive indexe(RI), pulsatility index(PI) and maximum velocity (Vmax). Ultrasonographic scans were performed before the induction of pancreatitis and once daily for five days after the induction. The RI, PI and Vmax were increased with day as follows; the RI prior to induction was 0.625$\pm$0.096 (mean$\pm$SD), the PI was 1.117$\pm$0.289 and the Vmax was 0.349$\pm$0.094 m/s. After five days, the RI was 0.727$\pm$0.051 (p<0.0l), the PI was 1.480$\pm$0.284 (p<0.0l) and the Vmax was 0.585:$\pm$0.114 m/s (p<0.00l). These results show that there is some relation between the increase of the RI, PI and Vmax of cPDAF and the progress of acute pancreatitis in dogs. Therefore, the measurements of the hemodynamic changes of cPDAF may be a valuable technique for the evaluation of acute pancreatitis in dogs.

이 연구는 시각장애학교 이료재활전공과 졸업생들의 교육 경험과 개선 방안에 대한 인식을 조사하는 것이 목적이었다. 연구 참여자는 2019년 2월 기준 전국 시각장애학교 12개교의 졸업생 총 104명 중 71명이었다. 이 연구에서 사용한 조사도구는 선행 문헌을 기초로 구성한 설문지로서 참여자에 관한 기초 사항, 이료재활전공과 교육 경험 및 이료재활전공과 교육 개선 방안 등 3개 분야로 구성되었다. 연구 참여자들은 전반적으로 이료재활교육에 대해 만족하고 있었고, 다른 중도 실명 시각장애인에게 이료재활전공 교육을 추천하겠다는 의견을 제시하였다. 이료재활전공과 졸업생들이 바라는 이료재활전공과 교육의 개선 방안은 이료재활전공과에 적합한 교육과정 개발, 실기 과목 수업 시수 증가, 시각장애인 자립생활 관련 과목 개설 확대, 저시력 학생의 특성을 반영한 교과서 제작⋅보급, 이료 수업의 모형과 교구 사용 등이었다. The purpose of this study was to explore the implications for improving the educational system and curriculum of riryo by investigating the graduates experiences and opinions from special schools for students with visual impairments. A total of 71 graduates from riryo rehabilitation programs of such special schools in February, 2019, participated in this study, which asked them by phone about their educational experiences and opinions on the directions for improving riryo education at the special schools. Overall, the graduates were satisfied with the riryo rehabilitation programs and thought that the program had much influence on their current jobs. The graduates proposed the following directions for improving riryo rahabilitation programs: (a) the development of riryo rehabilitation curriculum different from the curriculum for high school students; (b) the increase in the number of credit hours for practice-oriented subjects; (c) the expansion of the extended core curricular subjects (i.e., braille, orientation & mobility, daily living skills, and assistive technology) for the riryo rehabilitation program; (d) the production and dissemination of textbooks reflecting the needs of students with low vision; and (e) the wide use of models or devices for practical and concrete instruction in riryo subjects.
