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.

This study was designed to examine the relationship between clinical symptoms, self-efficacy, and performance of women with osteoarthritis. It is a survey study of 60 women who were diagnosed as osteoarthritis and given medical treatments from September, 2005 to October, 2005 in hospital 'H' located in Yongin-si. For clinical symptoms, radiographs of the subjects' knees were taken and evaluated the pathology grade by the Kellgren-Lawrence grade. Pain and stiffness was measured by the measure of WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index), and functional reach test was measured in order to examine balancing abilities. Self-efficacy was measured by a tool which has revised the ASES (Arthritis Self-Efficacy Scale), and performance was measured by recording the difficulty of the WOMAC measurements themselves, and the time taken for 20 m walking, going up and down 9 stairs, and 5 sit-down and stand-up repetitions. The resulting differences in the other variables according to performance and the relationship between performance with variables are the following. First, an increase in pain in women with osteoarthritis led to decreased functional ability. Second, an increase in stiffness in women with osteoarthritis led to a decrease in functional ability. Third, a decrease in balance in women with osteoarthritis led to a decrease in functional ability. Fourth, a decrease in self-efficacy in women with osteoarthritis led to a decrease in functional ability. Fifth, the variables for estimating the performance by self-report were pain and self-efficacy. The variables for estimating the performance by recording the time taken was balance and self-efficacy. As a result factors such as pain, balance and self-efficacy in women with osteoarthritis were closely related to performance. Based on the results, it seems that physical therapy programs to decrease pain and to increase the balance in women with osteoarthritis, and psychological approaches to increasing self-efficacy are needed. I hope that the results of this study will be useful data for clinical management and intervention for women with osteoarthritis.

The present study is a preliminary research improving the dwelling quality of one-room type multi-family housings around the university campus. The purpose of the study is to investigate the present condition of Indoor noise level using · residents' responses and field measurements. The respondents are 104 residents living in one-room type multi-family housings. The field measurements on equivalent noise level of indoor and outdoor were carried out in 6 subject house units during the $26th\~28th$ of November 2002. The results are as follows. 1) The residents show relatively non-positive responses at evening and night on the present condition of indoor noise. 2) They answer 'living equipment foise' and 'water hammer' as major types of indoor noise of house unit. 3) Outdoor noise levels, basic factor of noise environment in 6 subject buildings were distributed $52.8\~65.3dB(A)Leq_{5min}$ and were inappropriate to the standard for environmental noise, $55 dB(A)Leq_{5min}$. 4) Indoor noise levels of subject house units were measured as $27.5\~63.5dB(A)Leq_{5min}$, the average of each house unit except one house unit was higher than the level feeling as noise, 40dB(A). 5) It was found that the differences of indoor noise levels between subject house units were caused by 'residents' living noise', 'living equipment noise', 'water hammer', and 'walking and talking noise in stairs and corridors'. 6) Therefore, it is required to plan for improving the quality of noise environment in one-room type multi-family housing around the campus. For example, soundproof construction (including double window with pair glass and balcony), outdoor garden with trees and water for increasing natural sound, interior materials with sound absorbing power to absorb living noise, soundproof pipe or double surface pipe for decreasing 'water hammer', and noiseproof floors, etc. are required.

This study was done to determine the situations of stress incontinence(SI) and the differences in general characteristics, obstetrical history and SI related variables between women with stress incontinence and normal women. The design for study was a descriptive study. The number of subjects consisted of 156 women who were selected by systematic random sampling in Kwangju city. Data collection was done with the modified Hendrickson's Stress Incontinence Scale(1981) which was analyzed using frequency and percentiles. The results were as follows : 1. The stress incontinence (SI) rate of the sample was 64.1% and the majority of the women(40.9%) had experienced SI for a period of five years(the mean period was 2.7 years) without any treatment or care(83.0%). The amount of SI was from one drop(40.0%) to one teaspoon(16.7%) daily. 2. Items on the SI scale had the scores ranging from 4 to 44 with a mean score of 13.7 which showed mild SI. 3. The priority of provocative factors for SI were abdominal tightening(83%), coughing(58%), laughing(52%), sneezing(40%), steeping(18%), sudden standing(17%), nose blowing(13%), heavy exercise(11%), rapid walking up-stairs(10%) and excitment (9%) in that order. 4. There were no significant differences in age, education, spouse, job and income between the women with SI and the normal women. 5. There were no significant differences in the age at the last delivery, age of last baby. number of vaginal, or cesarean deliveries, or abdominal operations between the women with SI and the normal women. It can be concluded that SI in women has a high incidence nth various provocative factors but it is relatively mild SI on a daily basis and generally there has been no treatment. It is suggested that a descriptive study of emotional problems and precipitating variables in SI women will increase the knowledge of SI.

Purpose: This study was conducted to determine the structural change in knees caused by quadriceps angle and the muscle activity in lower limbs. Indirect intervention was provided by using taping for stability in the ankle joints, which affected patellofemoral pain. Methods: The subjects in this study were 20 patients with patellofemoral pain who visited ${\bigcirc}{\bigcirc}{\bigcirc} $ Hospital in Busan. The visual analogue scale measured the dynamic quadriceps angle and the degree of pain felt by the patients while walking down stairs, which was a known factor of patellofemoral pain. In addition, muscle activities in the rectus femoris, vastus lateralis, vastus medialis, tibialis anterior, peroneus longus, and biceps femoris, which affect the knees and ankles, were measured using surface electromyography. The muscle activities were converted into %RVC for this study. The data obtained in this study were analyzed with the Wilcoxon signed-rank test using the SPSS Ver. 25.0 statistical program. The significance level ${\alpha}$ was 0.05. Results: The study results showed that the pain and dynamic quadriceps angle were significantly reduced statistically when applying the calcaneus fixation taping (p<0.05). Muscle activity in the lower limbs was significantly decreased in the vastus medialis, vastus lateralis, and tibialis anterior (p<0.05). Conclusion: The summary of the study results verified that the calcaneus fixation taping reduced the pain and dynamic quadriceps angle by providing stability in the ankle joints. It also produced efficient movement due to the difference in lower-limb muscle activity.

Purpose: The purpose of this study is to compare variant analysis results regarding overcrowded spaces and suggest a space analysis model for women's hospitals at the outpatient clinic department, central treatment department, and inpatient ward considering evacuation capability of newborns unable to perform automotive evacuation, pregnant patients and maternal patients with limited mobility. Methods: Firstly, precedent studies on women's hospitals and evacuation in hospitals were reviewed. Secondly, the analysis conditions and necessary set values for simulation were designed after analyzing the design documents of the research target hospital. Thirdly, evacuation simulation was conducted by adjusting the variables related to the evacuation behavior of inpatients and newborns. Fourthly, based on the derived results, overcrowded spaces were compared and analyzed according to evacuation behavior. Result: The study results are as follows: (1) It is necessary to check the main escape routes for occupants and to expand and adjust the size of mainly used entrances. (2) It is necessary to widen the stairs' width to alleviate overcrowding caused by patients with non-autonomous walking. (3) Due to overcrowding of the main escape route, it is necessary to identify the bypass route and adjust the width of the corridor. (4) It is necessary to plan an evacuation route for newborns to escape from the main escape route for occupants. Implications: The study result is expected to be used as primary data for research that considers the evacuation behavior of newborns and pregnant women in women's hospitals.

As the world's elderly population increases, the proportion of visually impaired is also increasing, and there are still many restrictions on the use of outside activities, such as safety problems and lack of guidance information. To solve this problem, research on smart devices such as smart glasses with optical character recognition (OCR) function is being actively conducted. In this paper, we propose a system that recognizes obstacles ahead and informs information by voice, and also guides the way to the destination. Using the deep learning object recognition model Yolo, it let them to recognize the risk factors as obstacles such as stairs and Larva cones. and it also deliver the information with a voice. so you can expect that the visually impaired can do a lot of different activity even more now that system takes the visually impaired to the destination by using the directions API, voice recognition, TTS library.

Pedestrian facilities encompass pedestrian roads, stairs, and queuing areas exclusively designed for pedestrian use. The Korean Highway Capacity Manual provides guidelines for analyzing the capacity and level of service of pedestrian facilities. However, there is a lack of analysis methods tailored specifically for pedestrian facilities. Therefore, in this study, we introduced a new standard of pedestrian space to account for changes in the Korean body ellipse. Furthermore, based on this newly defined pedestrian space, we proposed a new standard value for the level of service of queuing areas. The results of on-site surveys confirmed that the proposed level of service can effectively reflect the actual walking situation.
