The purpose of this study was to investigate donning and doffing independence of the disabled individuals. The subjects of this study were who had kinetic disabilities on upper-limbs. 31 women and 38 children were participated in the survey. They were classified with six groups according to their upper-limbs' kinetic ability levels. Three upper-limbs' kinetic abilities were adopted: Lifting arms up to the chest, twisting shoulder to throw arms toward the back, and buttoning clothes by oneself. The independency of donning and doffing of 14 upper-body garment styles were evaluated by subjects. The donning and doffing independency of 14 garment styles was significantly differentiated by the level of kinetic abilities and garment styles. The person who able to button clothes by oneself could don and doff clothes by oneself. The results also revealed that the independency of donning and doffing was significantly different between cerebral palsy and apoplexy groups. The persons having a stroke of apoplexy were more likely to be able to dress independently than the persons with cerebral palsy. The persons with a paralysed arm were more likely able to wear ready-to-wear clothes of various styles. The donning and doffing independency was also significantly differentiated by the styles of garments. The tight fit style garments were more difficult to be dressed independently than the loose fit style garments. The jacket and shirts, which were buttoned from neck to bottom, were more difficult to be dressed independently than T-shirts.

The prevalence rate of low back pain in nurses is higher than that of other jobs, because there are many more risk factors(for example, standing postures, lifting and carrying heavy loads, transfering patients, changing a patient's position etc.). This investigation is to provide basic data for prevention of low back pain by analyzing the prevalence rate and related factors of low back pain in nurses(esp. operating room staff) in general hospitals. A self-reported questionaire survey was carried out on three hundred and five nurses of three general hospitals in Seoul from June, 1996 to August, 1996. Subjects of the survey were divided into a low back pain group(LBP) and a cotrol group to investigate the association between low back pain and the general characteristics and work related factors of each group. The results were as follows: 1. In the subjects of the survey, the prevalence rate of low back pain was 60.0% for the last year. 2. 73.6% of operating room(OR) staff complained of low back pain. 3. Standing for a long time and working in twisting postures were associated with low back pain, and so were the shift, the type of work, and the frequency of transfering patients. 4. The weight loads which nurses frequently carried were, under 5kg, 5-10kg, 15-20kg, 15-20kg, over 20kg, and all, except for 10-15kg, were associated with LBP. 5. 76.9% of the LBP experienced low back pain within 3 years after starting nursing jobs. 6. Concerning the degrees of low back pain: 75.8% was limited to waist; 18.8% reached the knees; 4.2% reached ankles. In conclusion, the prevalence rate of low back pain in general hospital nurses was associated with the works in operating room and other work related factors, therefore it is necessary to develop on educational program for the prevention of low back pain as well as and to improve working environments.

Objective: This study was performed to evaluate the child-care teachers' job in relation to physical work. Background: Child-care teacher is directly related to the quality of child care. And their physical activity is higher than general education teachers because the proportion of day care is high. But analyzes of child-care teachers' job burdens and the work environment associated with physical activity is not well established. Method: To conduct this study, the child-care teachers' job was classified into 18 physical works. After classification, posture was evaluated by ergonomic posture evaluation schemes of OWAS, RULA, REBA and evaluated for each physical part. Next, musculoskeletal subjective symptoms were analyzed. Results: The results showed the following: The highest assessment on the posture evaluation was "helping children to ride a school bus", "feeding: meal/snack", "brushing children's teeth" and "arrangement of nap-stuff". The rank of high-risk assessment on the neck/trunk/leg part was arranged by: "feeding: meal/snack", "helping children to ride a school bus", "making nap", "arrangement nap-stuff" and "brushing children's teeth". The rank of high-risk assessment on the upper limbs part was arranged by: "helping children to ride a school bus", "the bust - group activity", "meal/snack time - preparing, feeding, arrangement", "nap time - preparing, arrangement", "brushing children's teeth", and "using the toilet". According to the results of each musculoskeletal subjective symptom, teachers ordered the pain area as follows: waist, shoulder, leg/feet, and neck, and they showed more pain on trunk than the upper limbs. Conclusion: To sum up the results from ergonomic posture evaluation and a subjective symptom, the following are high working pressures: "feeding: meal/snack", "the bust - group activity", "making nap", "brushing children's teeth" with deep bending and waist twisting, "helping children to ride a school bus", "brushing children's teeth" with lifting shoulder; "meal/snack time - preparing, arrangement", "nap time - preparing, arrangement", and "using the toilet" with moving or an up-down position in their job. Application: The results of this study might be information for improvement of the child-care teachers' job environment.

이 연구는 동서양 춤 동작의 원리를 비교하는 것으로 다리와 팔을 동시에 움직이는 즉, 한쪽 다리로 신체를 지탱하는 공통점을 지닌 수족상응(手足相應) 동작에 대하여 형태학적으로 접근하였다. 따라서 발레에서는 아라베스크(arabesque), 데벨로뻬(developpe), 아띠?드(attitude) 동작을 수족상응 동작의 예로 제시하였고, 한국무용에서는 탈춤의 외사위, 겹사위, 멍석말이 등을 포함한 민속무용의 수족상응 춤사위를 고찰하여 이들 춤에서 나타나는 형태학적 특징을 인종의 형질적 측면, 춤의 사상적 측면, 동작의 조형적 측면으로 탐색하였다. 그 결과 수족상응 동작의 형태에 나타난 양태는 다음과 같다. 첫째, 인류의 생태와 관련하여 인종의 형질이 동서양간 각각 다르기 때문에 무용수의 체격이나 체형은 춤의 형태를 다르게 발달시켰다. 따라서 발레는 긴 팔과 다리를 이용하여 신전하는 형태의 춤으로 수족상응 동작에서 신체의 한계선을 더욱 확장시킴으로써 우아하고 아름답게 보일 수 있도록 하였다. 반면 우리나라는 농업이 생업이었으므로 항상 땅과 가까이 한 탓에 체격이 왜소해졌고 이 때문에 춤사위는 '휘젓는 춤사위'와 '굴신걸음'으로 발전하여 대부분의 수족상응 동작에서도 이와 같은 형태를 취하고 있는 것으로 나타났다. 둘째, 동서양간의 자연관에 따라 동일한 형태의 수족상응 동작임에도 불구하고 발레는 천향(天香)을, 한국무용은 지향(地響)의 형태를 띠고 있다. 이것은 수족상응 동작의 원리가 땅을 지향(地向)하는 것임에도 불구하고 서양인의 사상과 추구하는 미적 가치가 천향(天向)을 지향(志向)하고 있기 때문인 것으로 추측된다. 셋째, 발레에서 미(美)의 초점은 외형으로 나타난 아름다운 동작 그 자체에 있다. 따라서 수족상응 동작에서도 신체가 완벽한 균형을 이룰 수 있도록 팔과 다리의 위치 및 각도를 규정하고 있다. 반면 한국무용의 수족상응 동작은 대부분 일상생활에서 나오는 자연스러운 움직임과 일의 능률을 올릴 수 있는 움직임에서 발전된 동작임으로 신체가 다소 불균형을 이루더라도 멋스러운 기교로 간주하고 있음을 고찰하였다.
