The parking area for the disabled is a parking facility for the pedestrian disabled and is a parking space for securing pedestrian safety passage for the disabled. However, due to the lack of social awareness of areas for the disabled, the use of parking areas is restricted, and violations such as illegal parking and obstruction of parking are increasing every year. Therefore, in this study, we propose a system to crack down on illegal parking in handicapped parking areas using the YOLOv5 model, a deep learning object recognition model to improve parking interference within parking spaces.

Objective: To investigate the effect of long-term water exercise on gait parameters in the elderly post stroke patients. Design: One group pretest-posttest design. Methods: Twenty elderly post stroke patients (age: $56.5{\pm}10.1$ years, height: $168.6{\pm}5.8cm$, body mass: $69.3{\pm}6.9kg$, handicapped level: $2.5{\pm}0.8$) participated in this study. Participants took part in gait training of 1 hour per day, three days per week, for three months. Participants' gaits were analyzed to find the effect of 3 months water exercise by a 3-D motion analysis with 8 infrared camera and 1 force plate (sampling frequency: 100 and 1,000 Hz, respectively). A paired t-test was used to find the significance with significant level as 0.05. Results: Gait velocity, step length & step width significantly increased, and asymmetric index for gait parameters significantly decreased after the water exercise (p<0.05). Conclusions: The water exercise effectively affect on patients' gait ability and electromyography analysis will be needed further study.

Many studies have shown that the parents of developmentally disabled children are adversely affected by the experience of raising a child of this type. However, the range of reactions to parenting a handicapped child is quite varied and is presumably affected by a wide variety of variables. This study examined a number of demographic and psychosocial variables to determine which particular combination could best predict the current level of stress and coping behavior of mothers. Among predictor variables, marital satisfaction and dysfunctional attitude are variables that I am particularly interested in which can mediate parental stress. Five variables are found to be related to the stress of mothers, that is, level of disability, level of needed help, marital satisfaction, type of disability, father's education level. Also variables that affect four different types of stress (which are four factors of QRS-F) are analysed and the results presented. Among these variables, some are pre-determined and some are intervenable. We should make an effort to make changes in those intervenable variables such as marital satisfaction, beliefs and attitude about disability, and level of needed help. In future research we need to search and clarify the beliefs and attitude that help mothers adjust to a life with a disabled child. Also governmental support and policy making to reduce the burden of these mothers should be accompanied as well.

Objective : The purpose of this research is to examine the effects of Gleditsiae Spina (GS) extract on immune cells and cytokines in ovalbumin (OVA)-induced asthmatic mice. Methods : In vivo, C57BL/6 mice were sensitized and handicapped by OVA for 12 weeks. During this experiment, the one group was then treated with GS extract for the later 8 weeks (3 times per week) and analyzed by ELISA, flow cytometer and RT-PCR. Results : In vivo, there were significant decreases in eosinophils, IL-4, IL-5, IL-13, IgE in BALF (bronchoalveolar lavage fluid). However, $IFN-{\gamma}$ in BALF of GS group increased significantly, compared with that of control group. Additionally, the population of $CD3e^-/CCR3^+,\;CD69^+/CD3e^+,\;IgE^+/B220^+,\;CD11b^+/Gr-l^+$ cells in the GS group decreased. Conclusion : The results of this study support a role for GS as an effective treatment for asthma in its experimental success in significantly decreasing inflammation and asthma reactions, and in increasing $IFN-{\gamma}$, which helps prevent such reactions.

The primary purpose of this study was to determine the reliability of lumbar flexion and extension range-of -motion measurements obtained with the modified -modified $Sch{\ddot{o}}ber$ methods on normal and subjects with low back pain. Sixty two, aged 20 to 30 years(x = 22.0, SD = 2.07), with normal and twenty two, aged 14 to 66 years(x = 35.6, SD = 15.88) with chronic low back pain were measured by two physical therapist with 3 to 10 years (x = 6.5) of clinical experience. The therapist used the modified-modified $Sch{\ddot{o}}ber$(MMS) techniques to measure, in random order and on two occasions, the subjects' lumbar flexion and extension. For therapist 1, Intraclass correlation coefficients(ICC) for test-retest reliability for normal varied .9923, .8802(flexion, extension). and low back pain pateint varied .9950, .9313(flexion, extension). For therapist 2. ICC. for test-retest reliability for normal varied .9903, .8921(flexion, extension). and low back pain pateint varied .9843, .9551(flexion, extension). Interrater reliability for normal varied .9477, .6960(flexion, extension) and low back pain pateint varied. 9776, .7576(flexion, extension). Thus the MMS. method appears to be a reliable method for normal and patient with low back pain.

BCI (Brain Computer Interface) is technology to control external devices by measuring the brain activity, such as electroencephalogram (EEG), so that handicapped people communicate with environment physically using the technology. Among them, EEG is widely used in various fields, especially robot agent control by using several signal response characteristics, such as P300, SSVEP (Steady-State Visually Evoked Potential) and motor imagery. However, in order to control the robot agent without any constraint and precisely, it should take advantage of not only a signal response characteristic, but also combination. In this paper, we try to use the fusion of motor imagery and P300 from EEG for practical use of robot control in BCI environment. The results of experiments are confirmed that the recognition rate decreases compared with the case of using one kind of features, whereas it is able to classify each both characteristics and the practical use technology based on mobile robot and wireless BCI measurement system is implemented.

Korean railroad company is continuously improving the service for the disabled. They also install and reform many facilities for them. However, It is not considered the importance of egress when fire occurred in a cabin Now, Fire hazard analysis and risk assessment are introduced into domestic regulations for improving fire safety performance of train car and railroad facilities. Considering the fact that fire safety evaluation process doesn't fully include disabled person, fundamental egress data for them is very important for life safety aspect. In this paper, Egress experiments and analysis were conducted to measure the movement speed of the disabled with Mugunghwa and Saemaul.

Resistive therapeutic exercise prescription goal is to improve functional performance and capabilities through the development of increased muscular strengh endurance or power. Resistance can be applied to either dynamic or static muscle contractions. Resistive therapeutic exorcise can be carried nut concentrically, eccentrically, isometrically, isokinetically. Neurodevelopmental treatment has not resistive therapeutic exercise concept. But proprioceptive neuromuscular facilitate techniques have resistive therapeutic exercise concept with pattens and techniques. It is aid muscle contraction, motor control and increase strength. Manual muscle testing will help the therapist establish a qualitative and quantitative baseline level of strength. Manual resistance maybe applied a against controlled lengthening contraction re static contraction of a muscle. A repetition maximum is not easy to calculate and is not the most accurate method available today to measure strength before of after a resistive therapeutic exercise program. Oddvar Holten Diagram is essy to calculate and is the most accurate method available today to measure strength before of after a resistive therapeutic exercise program. Plyometric training emphasize the development of muscular power and coordination. Quick bursts of force in functional movement patterns are often necessary of a patient is to return to high-demand occupational, recreational or sports related activities.
