저자들은 결절성 경화증에서 흔하게 동반될 수 있는 SEGA가 있는 환자에서 GK-SRS를 시행하여 초기 경과가 좋았으나, 재발을 하여 결국 수술적 절제를 시행하게 된 증례를 경험하여 이를 보고하였다. Subependymal giant cell astrocytoma (SEGA) is the most common brain tumor that develops in 5-20% of patients with tuberous sclerosis complex. Although these lesions are slowly growing tumor, they can cause morbidity and mortality due to acute hydrocephalus because of their prevalent location near the foramen of Monro. Surgery has been the standard care for SEGAs demonstrating serial growth and symptomatic hydrocephalus. However, not all SEGAs are treatable by complete surgical resection. Gamma Knife stereotactic radiosurgery can be considered as a second option, but it has shown highly variable responses in patients with limited data. In recent years, drugs with novel mechanism, sirolimus and other mammalian target of rapamycin (mTOR) inhibitors have been found to reduce the size of SEGAs. We report a case of treatment of SEGA with gamma knife surgery which continued for two years without progression, even though surgical resection was done, finally.

The Korean character recognition technology for user interface in multimedia terminal requires fast processing time and high recognition rate. In this paper, we propose an phoneme and character recognition technology which uses characteristic information of korean and features of input strokes, i.e, feature point, feature vector, virtual vector, position relation between strokes. And, a recognition both phoneme and character by the various writing types of users uses korean database. The Korean database has been constructed by the characteristic information of korean and phoneme models which have various stroke information. Also, we use successive processing by the position relation between strokes and backtracking processing by the modification processing of stroke numbers which composed of each phoneme. This method reduces the complex processing of phoneme separation. The proposed on-line korean character recognition system has obtained 13msec average character processing time and correct recognition rate more than $95{\%}$ In a recognition experiment, where we tested 600 characters written by 10 people among 1,200 words.

PURPOSE: This study examined effects of the untact trunk stabilization exercise program on muscle thickness, trunk strength, maximal expiratory flow, and static balance. METHODS: The subjects were 20 normal adults divided into 10 in the contact exercise group and 10 in the untact exercise group. The trunk stabilization exercise program was conducted for four weeks. The muscle thickness was measured using ultrasound. The maximal expiratory flow was measured using Personal Best Full Range Peak Flow Meter. The static balance was measured through Bio-rescue; and the trunk muscle strength was measured by bending the upper body forward and measuring the time for maintaining the posture. RESULTS: Both contact and untact exercise groups showed significant differences in muscle thickness, muscle strength, maximal expiratory flow, and static balance (p < .05). A significant difference in muscle thickness on ultrasound was observed between the contact and untact exercise groups (p < .05). CONCLUSION: Activation of the transverse abdominal muscle requires accurate instructions of the contact exercise, but despite environmental constraints, the untact exercise program is as effective as the contact exercise for improving muscle strength, maximum expiratory flow, and static balance.

PURPOSE: This study examined the effects of coordinative locomotor training on the physical factors for falls in the elderly with mild cognitive impairment. METHODS: This study examined thirty subjects diagnosed with mild cognitive impairment by the radiologic findings, history, and physical examination. The subjects were assigned to a control group (n = 15) or experimental group (n = 15, coordinative locomotor training). The experimental group underwent coordinative locomotor training for four weeks, with training sessions two times per week. The control group was given a fall-prevention education for 60 minutes without coordinative locomotor training. To evaluate the physical factors for falls, the lower extremity strength and the Korean version of the Fullerton advanced balance scale and biorescue were measured for balance. These tests were conducted before and after training. RESULTS: Significant differences were observed between the two groups after the four weeks of coordinative locomotor training for the elderly with mild cognitive impairment the experimental group had a greater degree of improvement in the physical factors for falls. CONCLUSION: These findings suggest that coordinative locomotor training may have a functional effect on fallprevention and the mobility of the elderly with mild cognitive impairment. In addition, it is expected to provide systematic and effective data that can be used as a fall prevention program for the elderly with mild cognitive impairment in each institution.

PURPOSE: This study examined the effects of videoconferencing- based telerehabilitation exercise program on the gait, knee function, and quality of life of patients with knee osteoarthritis. METHODS: Forty-eight subjects, who were diagnosed with osteoarthritis of the knee by the radiologic findings, history, and a physical examination, were assigned randomly to a Control group, Experiment group I, and Experiment group Ⅱ. The control group did not perform any exercise program and were educated in understanding and managing the disease of knee osteoarthritis for only one hour. Experimental groups I and Ⅱ were provided with an exercise guidelines book for knee osteoarthritis, and the same exercise programs were conducted by face-to-face visits and non-face-to-face using telerehabilitation for eight weeks, respectively. To verify the effectiveness of each exercise program, the gait speed, knee disability index, and health related quality of life were measured. All assessments were conducted twice before and after the intervention. RESULTS: The participants who underwent both face-toface and telerehabilitation exercise programs showed an improved gait speed, knee function, and health-related quality of life. In particular, there was no significant difference between the telerehabilitation exercise group and the direct face-to-face exercise group in improving the knee joint function and health related quality of life. CONCLUSION: A these findings the telerehabilitation exercise program for patients with knee osteoarthritis can alternate or supplement the face-to-face exercise program. Therefore, the telerehabilitation exercise program should be used not only as a substitute supplement program but also as an intervention for various diseases.

인터렉티브 멀티미디어 학습교재를 학습활동에 이용하는 경우, 매체의 다양한 속성으로 학습자의 흥미를 끌 수 있을 뿐 아니라 학습효과의 향상도 기대한다. 본 연구에서는 멀티미디어 매체를 대표하는 CD-Rom 타이틀이 학습자의 학습활동과 어떻게 구체적으로 관련이 있는지를 ‘상황화된 학습(situated learning)’이라는 개념을 적용하여 멀티미디어 매체 학습과정을 분석하고자 하였다. 각기 다른 5가지의 멀티미디어 학습타이틀을 이용하여 1차(33명)와 2차(24명)에 걸쳐 초등학교 3학년의 학습상황과 학습행동을 살펴보았다. 멀티미디어 타이틀에 대한 초등학생들의 반응은 학습타이틀의 내용 구조와 각 타이틀이 제공되는 상황에 따라 차이가 났다. 순환적인 내용 구조를 가진 타이틀이 위계적 이거나 선형적, 또는 유사 선형적인 내용구조에 비해, 학습자에게 다양한 행동과 흥미 반응을 더 유발하는 것으로 나타났다. 타이틀의 내용구조의 특성에 따라, 학습자에게 역할을 제공하는 상황이 달라질 뿐 아니라, 긍정적인 행동반응을 더 유도하는 것으로 나타났다. 멀티미디어 학습타이틀들이 학습보조물로서 많이 등장하는 상황에서, 타이틀의 매체적 특성보다는 내용구조에 따라 학습자의 행동방식이 체계적으로 달라진다는 본 연구결과는 멀티미디어 매체의 디자인과 내용 기획 그리고 실제 학습활동에서의 활용의 측면에서 시사점을 제공해준다. Interactive multimedia title has taken a position of attracting learner’s attention and increase learning by various media effect when they were applied in learning. In this study, we have tried to analyze the relation between the multimedia CD-Rom title and its impact on learning activities with a view of ‘situated learning’. With 5 different kinds of multimedia titles, third grade of elementary school children has participated in two sessions of studies of exploring the titles: 1st session(33 children). 2nd session(24 children). The behavior pattern of children and their response on usages of titles were analyzed in relation to the content structure of titles. There were differentiated response patterns in accordance with the content structure and the learning situation. The recursive content structure has attracted higher active engagement responses of children than those from the linear of semi-linear content structures. This content structure provides a diverse acting situation for the learner and facilitates higher participatory behavior to the learning situation. The results have implied that when the multimedia titles were used for learning material, they could have more impacts not by their diverse media effects, but by the content structure of titles to improvise the interactive nature of learner and learning situation.
