눈-손 협응력은 시각정보를 손의 운동 정보에 적용시키는 뇌의 능력으로 일상생활을 하거나 복잡한 운동 기술을 발휘하는데 필수적인 기능이다. 본 논문은 눈-손 협응 능력이 발달하는 과정에 있는 아동을 대상으로 게임을 통해 눈-손 협응력 훈련을 진행할 수 있는 가상현실 콘텐츠를 제작하였다. 제작된 가상현실 콘텐츠는 눈과 손 인터페이스를 통해 가상현실의 물체와 상호작용하도록 요구함으로써 게임형식으로 과제를 제공한다.

Objective : The purpose of this study was to investigate the effects of bimanual intensive training on Upper Extremity Function and activities of daily living in stroke patients. Methods : The subjects were 18 patients who were diagnosed with hemiplegic stroke. They were randomly assigned to bimanual intensive training group (n=9) and unilateral intensive group (n=9). Bimanual training group performed bimanual task and unilateral training group performed one hand task for 1 hour per session, 5 times a week, for 4 weeks. Chi-square test, Wilcoxon signed rank test, and Mann-Whitney U test were used for analysis. Results : The results showed that, upper extremity motor function and bimanual coordination were significantly improved in patients in the bimanual training group (p<.05). Additionally, the ratio of affected hand use and amount of use/quality of movement in the hemiplegic upper extremity in activities of daily living for patients in the bimanual training group were significantly improved (p<.05). Although the unilateral group improved motor upper extremity function and activities of daily living in the upper extremity (p<.05), it was not significantly different from that in the bimanual training group. In between-group comparison, bimanual coordination and ratio of the affected hand use in a day were significantly different (p<.05). Conclusion : It is reasonable to conclude that bimanual intensive training therapy is an effective intervention method to improve upper extremity motor function, and activities of daily living in stroke patients.

Objective: The purpose of this study is to ob serve effects of CPM(Continuous Passive Motion) on hand functional and upper-extremity muscular strength rehabilitation for stroke patients. Method: Objects of this study, three patients have the symptoms of hemiplegia due to stroke. These are acute patients, within a 18 months after treatment and correspond in Brunnstrom stage 4~6. This study used single subject (A-B) design for three patients with a stroke and the effect of CPM was measured using Jebsen-Taylor hand function test, Purdue Pegboard test, hand muscular strength test. They received CPM for 3 weeks, 2 per day, 30 minutes for each, total 30 times. Results: Two patients' results of fingertip grip test in hand strength measurements did not change. Results of Jebsen-Taylor hand function test, Purdue Pegboard test and other hand muscular strength test were improved. To validate statistical results nonparametric statistical method, Wilcoxon signed ranks test was performed. P-Values are greater than 0.05 so difference between be fore and after treatment is not statistically significant result. Conclusion: Despite of limitation of short program period and fewer participants, CPM which has been conducted for stroke patients showed the effect on improvement of hand function and muscle strength. This study shows that CPM which is mainly used to treate lower-extremity rehabilitation can be use to improve performance of hand function and strength for patients with stroke.

The purpose of this study was to determine the relationships with physical activity and depression and body function in elderly. Methods: Total 79 elderly(over 65years old) were participated in this study. A Korean Form of Geriatric Depression Scale(KGDS), Mini-Mental State Examination(MMSE-K), Jebsen hand function test, dynamometer, five time sit-up test were used to measure the depression and cognition, body function(hand function, grasp power, lower extremity strength). Results: Physical activity participated group shows higher in the body function and lower in the depression than non participated group. Conclusion: The findings of this study indicate that the physical activity is helpful to indicate and manage the depression and body function in elderly.

수화는 청각장애인이 사용하는 시각적인 언어이다. OpenGL 기반의 가상 현실 공간에서 수화 동작을 표현하기 위해서는 수화 동작 데이터를 삽입하고 수정하는 편집 프로그램이 필요하다. 하지만, 기존의 수화 동작 편집기는 수화를 잘 이해하지 못하는 일반 사용자가 손 모양을 정확하게 편집하거나 얼굴 표정을 표현하는데 어려움이 있다. 또한, 수화 사전에 포함되는 각 수화 단어의 데이터 수가 많기 때문에 이를 효율적으로 생성하고 저장하는 프로그램이 절실히 필요하다. 본 논문에서는 사용자의 편의성을 높이기 위해 수화 동작 그래픽 편집기를 개선하는 방법을 제안한다. 이를 위해 각 손 모양에 대해 21 개의 파라마터로 구성된 데이터를 손가락 별로 분류한 후, 손가락 고유 기호로 변환하고, 손 모양 이름과 일련 번호를 부여하여 손 모양 데이터를 얻었으며, 유사한 손 모양을 그룹으로 묶은 손 모양 그룹 데이터를 구성하여 손 모양 데이터 사전을 구축하였다. 구축된 손 모양 사전을 수화 동작 편집기에 적용함으로써 사용자는 손 모양 그룹과 손 모양 이름, 일련번호를 선택하여 손의 각 관절 움직임을 쉽게 편집할 수 있으며, 이를 가상현실 공간에서 움직여 볼 수 있다. 또한, 얼굴 표정과 안색을 편집할 수 있는 기능을 추가함으로써 수화 동작 중에 얼굴 표정을 쉽게 표현할 수 있도록 하였다.
