  • In the event of a fire in a high-rise building, rapid evacuation through the stairwell is a very important factor in rapid evacuation. However, in the event of an actual fire, most of the occupants evacuate at the same time, resulting in a stay in the stairwell, reducing the evacuation speed. In Korea, conditions for buildings are created to evacuate quickly and safely while introducing performance-oriented designs to solve these problems, but there is no research data related to the evacuation speed due to joining in the event of vertical evacuation. Therefore, in this study, by analyzing the experiment conducted at W University in Japan, the density-speed relationship when staying in the staircase room was derived, and the regression equation was derived based on the results.

  • The study was conducted from November 1995 to May 1996 at the one general hospital in Seoul. The total subjects of this study were 412 patients who have the experience of fall accident, among them 31 was who have fallen during hospitalization and 381 was who visited emergency room and out patient clinic. The purposes of this study were to determine the characteristics, risk factors and results of fall accident and to suggest the nursing strategies for prevention of fall. Data were collected by reviewing the medical records and interviewing with the fallers and their family members. For data analysis, spss/pc+ program was utilized for descriptive statistics, adjusted standardized $X^2$-test. The results of this study were as follows: 1) Total subjects were 412 fallers, of which 245(59.5%) were men and 167(40.5%) were women. Age were 0-14 years 79(19.2%), 15-44 years 125(30.4%), 45-64 years 104(25.2%), over 65 years 104(25.2%). 2) There was significant association between age and the sexes ($X^2$=39.17, P=0.00). 3) There was significant association between age and history of falls ($X^2$=44.41. P= .00). And history of falls in the elderly was significantly associated with falls. 4) There was significant association with age and medical diagnosis ($X^2$=140.66, P= .00), chief medical diagnosis were hypertension(34), diabetis mellitus(22), arthritis(11), stroke(8), fracture(7), pulmonary tuberculosis(6), dementia(5) and cataract(5), 5) There was significant association between age and intrinsic factors: cognitive impairment, mobility impairment, insomnia, emotional problems, urinary difficulty, visual impairments, hearing impairments, use of drugs (sedatives , antihypertensive drugs, diuretics, antidepressants) (P < 0.05). But there was no significant association between age and dizziness ($X^2$=2.87, P=.41). 6) 15.3% of total fallers were drunken state when they were fallen. 7) Environmental factors of fall accident were unusual posture (50.9%), slips(35.2%), trips (9.5%) and collision(4.4%). 8) Most of falls occurred during the day time, peak frequencies of falls occurred from 1pm to 6pm and 7am to 12am. 9) The places of fall accident were roads(22.6%), house-stairs 06.7%), rooms, floors, kitchen (11.2%), the roof-top, veranda, windows(10.9%), hospital(7.5%), ice or snowy ways(5.8%), bathroom(4.9%), playground, park(4.9%), subway-stairs(4.4%) and public-bathrooms (2.2%). 10) Activities at the time of fall accident were walking(37.6%), turning around or reaching for something(20.9%), going up or down stairs09.2%), exereise, working07.4%), up or down from a bed(2.7%), using wheelchair or walking aids, standing up or down from a chair(2.2%) and standing still(2.2%). 11) Anatomical locations of injuries by falls were head, face, neck(31.3%), lower extremities (29.9%). upper extremities(20.6%), spine, thorax, abdomen or pelvic contents(l1.4%) and unspecified(2.9%). 12) Types of injures were fracture(47.6%), bruises03.8%), laceration (13.3%), sprains(9.0%), headache(6.6%), abrasions(2.9%), intracranial hemorrage(2.4%) and burns(0.5%). 13) 41.5% of the fallers were hospitalized and average of hospitalization was 22.3 days. 14) The six fallers(1.46%) died from fall injuries. The two fallers died from intracranial hemorrage and the four fallers died of secondary infection; pneumonia(2), sepsis(1) and cell lulitis(1). It is suggested that 1) Further study is needed with larger sample size to identify the fall risk factors. 2) After the fall accident, comprehensive nursing care and regular physical exercise should be emphasized for the elderly person. 3) Safety education and safety facilities of the public place and home is necessary for fall prevention.

  • 본 연구는 20 ~ 60대의 성인 109명 (남 54명, 여 55명)을 대상으로 13가지 대표적 신체활동에 대한 에너지 소비량(EE)및 신체활동 강도 (METs)를 휴대용 호흡가스 분석기($K4b^2$)를 이용하여 측정하고 이를 기준으로 가속도계(Actigraph $GT3X^+$)의 정확성을 성별에 따라 평가하였다. 그 결과를 요약하면 다음과 같다. 1. 휴대용 호흡가스 분석기로 측정한 보통 달리기를 제외한 모든 트레드밀 활동의 단위체중당 에너지 소비량과 METs값은 여자가 남자 보다 유의하게 높았다. 13가지 대표 활동 중 눕기, 앉기 및 서기와 같은 움직임이 없는 활동은 에너지 소비량이 가장 낮은 것으로 나타났고, 남자는 계단 올라가기 (에너지 소비량 포함)에서 여자는 8 km/h 속도의 보통 달리기 (에너지 소비량값 포함)에서 에너지가 많이 소비되는 고강도 활동으로 나타났다. 2. 가속도계 및 휴대용 호흡가스 분석기로 측정한 EE와 METs값을 비교한 결과, 남자는 계단 내려가기, 보통 걷기와 빠르게 걷기 활동에서 여자는 계단 내려가기를 제외한 모든 활동에서, 가속도계가 휴대용 호흡가스 분석기 보다 과소추정 하였다. 3. Compendium 2011 기준에 따라 강도를 분류하였을 때 가속도계와 휴대용 호흡가스 분석기는 저강도 활동에서 일치하는 비율이 가장 높은 (남자 88.3%, 여자 91.3%) 반면, 고강도 활동에서 가장 낮은 일치율을 보였고 여자 (58.3%)보다는 남자 (75.2%)에서 일치율이 유의하게 높았다. 4. 가속도계를 이용하여 EE 및 METs값 추정 시 준거도구와의 차이를 성별에 따라 비교하면, 계단 내려가기를 제외한 모든 활동에서 여자 보다 남자에서 오차가 작은 것으로 나타났다. 특히, 트레드밀 이외의 활동보다는 트레드밀 활동에서의 오차가 작은 것으로 나타났다. 본 연구는 다양한 연령대의 성인 남녀의 신체활동의 에너지 소비량 등을 휴대용 호흡가스 분석기로 측정하였다는데 큰 의의가 있으며 이와 같은 측정값은 한국인을 위한 활동분류표 개발 및 에너지 소비량 산출 시 활용될 수 있을 것이다. 추후 연구에서는 현재까지 개발된 다양한 가속도계 추정식의 정확성이 검증되어야 하며 향후 가속도계를 이용하여 EE 및 METs값 산출 시 필요한 추정식은 적용하는 신체활동 종류뿐만 아니라 성별에 따라 개발되어야 할 것이다.

  • Purpose: The purpose of this study was to assess the level of activities of daily living (ADL) in a group of community dwelling elderly. Methods: The subjects were 100 low-income elderly registered in a public health center. The data were analyzed using the SPSS/PC program. Results: The results were as follows: 1. The basic ADLs of the subjects were scored at 7 levels, and the mean score was 6.24 out of 7 points. The subjects did not necessarily require help from others, but might have needed more times or instrumental assists to perform ADLs. The lowest ADL score was reported on walking up to the stairs (5.05), for which the subjects did not need physical assistance, but needed a certain degree of supervision. The highest score was reported on self eating (6.74), followed by bowel management (6.60). 2. The mean IADL score of the subjects was 1.77 out of 4 points. indicating that the subjects were very independent in performing IADLs, without help from others. 3. In relation to general characteristics, the level of ADLs of the subjects was significantly different by age (F=6.65, P=.000), main activities (F=6.36, P=.001), perceived health status (P=4.66, P=.012), educational background (F=4.64, P=.03), marital status(F=4.62, P=.005), and major household income (F=4.15, P=.002). 4. The subjects' level of IADLs in relation to their general characteristics was significantly different by perceived health status (F=8.08, P=.001), major activities (F=7.33, P=.000), age (F=6.18, P=.000), family context (F=3.53, P=.018), religion (F=3.10, P=.019), marital status(F=2.62, P=.055), and major household income (F=2.31, P=.049).

  • In this study, we investigate characteristics of fall, requirements toward the impact protective clothing, design preferences, etc. to develop the fall impact protective clothing for the silver-aged women. Among the 242 women respondents aging 50s to 70s, 43% experienced the fall in recent 2 years. It is found that the fall mostly occurred in winter season and happened during the regular activities such as walking outside, going up and down stairs. Most of the respondents have no experience buying the impact protective clothing, but they expressed the fall impact protective clothing would help reducing the injury from falls. Moreover, the intention to purchase the impact protective clothing is increasing with an increasing target age. However, the respondents concerned with increasing volume and weight of clothing by the protecting pad inserted into the clothing. The respondents also claimed that the impact protecting clothing should not interfere with their regular physical activities. The survey showed that respondents preferred to embed the impact protective function in pants as a form of the protective clothing. For the design preferences on the pants, casual style and straight silhouette was preferred and stretch fabric was selected. The respondents preferred underwear made of cotton spandex blend with relaxed fit.

  • Osteoarthritis(OA) is a widespread, slowly developing disease with a high prevalence rate increasing with age. The most common big joints involved in OA is the knee, where the disease particulary strikes, causing difficulties in rising from a chair. climbing stairs, kneeling. standing, and walking. The primary complaints of these patients include pain, stiffness. instability, and loss of function. The purpose of this study was to assess the impact of self-reported symptoms and limited flexion, and limited extension on functional impairment in patients with knee osteoarthritis. In the data collection, a total of 206 who had visited the physiotherapy unit at six different departments of orthopedics were interviewed in K City from June to September, 2000. The results of the study summarized are as fellows: 1. There was a significant difference among different degree group of limited flexion(p<0.05). A group difference was demonstrated between <5 ${\sim}$ 15 and 16 > (F=16.21, p<0.05). In the relationship between the degree of limited flexion and the level of functional impairment, the h igher the range of limited flexion, the lower the level of functional impairment. 2. In the relationship between the degree of limited extension and the level of functional impairment, a group difference was revealed between the non-limitation group and the <10 and 11 < However, no significant difference was noted between 11 ${\sim}$ 20 and 21 >(F= 13.37, p<0.05). In conclusion, finding above suggest that functional impairment is closely correlated with limited tlexion and extenion

  • Purpose: Weight-bearing exercise is a type of physical exercise that is widely performed for rehabilitation after acquiring nervous-system diseases or sports-related injuries. It is one of the most commonly prescribed rehabilitation programs for strengthing of the lower extremities. Weight-bearing exercise is important for the conduct of such activity of daily living (ADLs) as walking, and up and down the stairs. The purpose of this study was to investigate the muscle activities during one-leg standing and one-leg squatting, the two most representative weight-bearing exercises. Methods: A total of 43 elderly (60~70 years old) males who could perform weight-bearing exercises were included in the study. During the one-leg standing and one-leg squatting, the electromyographic (EMG) signals were quantified as maximum voluntary isometric contraction (%MVIC) using surface EMG, and then the muscle activities of the lower extremities during the two exercises were compared. For statistical analysis, an independent sample t-test and one-way ANOVA were performed. Results: The results of the study are as follows: (1) in the one-leg standing, the activity of the gluteus medius was the greatest among the vastus medialis, vastus lateralis, bicep femoris, (2) in the one-leg squatting, the activity of the vastus medialis was the greatest; and (3) the activity was greater in the one-leg squatting than in the single-leg standing exercise. Conclusion: The one-leg standing and squatting exercises are suitable for strengthening the muscles for the prevention of and recovery from lower-extremity injury, and for functional ADL in elderly people. In addition, dynamic exercise was shown to be more effective than static exercise for strengthening the muscles.
