The Intranet has been widely used in information system of the client/server software model. Due to the middleware software, this Intranet could be constructed based on database management system. CGI script can be easily connected to database using these middlewares either locally or remotely. In this paper Intranet system for member adminstration is developed using the miniSQL, Perl and C. The user authentication technique is also incooperated to secure the system. This system can be applied to any system for member administraction of a certain organization.
Physiologic Assessment of Coronary Artery Disease: Focus on Fractional Flow Reserve
황도연,이주명,구본권 대한영상의학회 2016 Korean Journal of Radiology Vol.17 No.3
The presence of myocardial ischemia is the most important prognostic factor in patients with ischemic heart disease. Fractional flow reserve (FFR) is a gold standard invasive method used to detect the stenosis-specific myocardial ischemia. FFR-guided revascularization strategy is superior to angiography-guided strategy. The recently developed hyperemia-free index, instantaneous wave free ratio is being actively investigated. A non-invasive FFR derived from coronary CT angiography is now used in clinical practice. Due to rapid expansion of invasive and non-invasive physiologic assessment, comprehensive understanding of the role and potential pitfalls of each modality are required for its application. In this review, we focus on the basic and clinical aspects of physiologic assessment in ischemic heart disease.

This study developed a saccadic eye movement training program and attempted to verify its effectiveness as a tool for training saccadic eye movements in stroke patients. This study included 26 stroke patients. The subjects were classified into an experimental group and a control group through random allocation, and the King-Devick test was administered as the pre-test. After the pre-test, the experimental group performed an existing occupational therapy intervention and a saccadic eye movement training program intervention for a total of 16 sessions. The control group underwent existing occupational therapy and additional occupational therapy interventions. After four weeks, the experimental and control groups were re-tested. The time and number of errors in the King-Devick test before and after intervention in both groups showed statistically significant differences (p<.05), and both parameters in the King-Devick test decreased after the intervention. In addition, the time and number of errors in the King-Devick test in the experimental group after the intervention were significantly lower than those in the control group (p<.05). This study showed that the saccadic eye movement training program had a positive effect on saccadic eye movements in stroke patients. 목적: 본 연구는 단속성 안구운동 훈련 프로그램(Saccadic Eye Movement Training Program)을 개발하고, 효과성을 검증하여 뇌졸중 환자의 단속성 안구운동 훈련을 위한 도구로써의 역할을 제시하고자 하였다. 방법: 본 연구는 뇌졸중 환자 26명을 대상으로 하였다. 대상자는 무작위 배정을 통해 실험군과 대조군으로 나뉘었고, King-Devick test로 초기평가를 진행하였다. 초기평가후 실험군은 기존 작업치료 중재와 단속성 안구운동 훈련프로그램 중재를 총 16회 동안 실시하였다. 대조군은 기존작업치료 중재와 추가 작업치료 중재를 실시하였다. 4주 후실험군과 대조군에게 재평가를 진행하였다. 결과: 실험군과 대조군의 중재 전⋅후 King-Devick test 의 시간과 오류 횟수 모두 통계학적으로 유의미한 차이를보였고(p<.05), 중재 전보다 후에 King-Devick test의 시간과오류 횟수가 감소하였다. 또한, 중재 후 실험군의 King-Devick test 시간과 오류 횟수가 대조군보다 통계학적으로 유의미하게 더 낮았다(p<.05). 결론: 본 연구를 통해 단속성 안구운동 훈련 프로그램이뇌졸중 환자의 단속성 안구운동에 긍정적인 영향을 주었음을 알 수 있었다.
