Pruritus is [CHECK DEFN] itchy feeling of one's skin. We often face stroke patients who complain about Pruritus. They occasionally fail to fall asleep or have a secondary infection as a result of scratching. For these reasons, severe Pruritus brings down general condition and interferes with recovery. The causes of Pruritus are distributed to from skin diseases and from internal diseases. Especially among the skin diseases, Xerotic Eczema, which is called Senile Eczema causes the dry skin in the elderly, especially lower limb's extensor part. According to the epidemiology, 20% of the old have Xerotic Eczema. In oriental medicine, Pruritus is called Pungsoyang(風瘙痒), Pungyang(風痒), Yangpung(痒風), Sinyang(身痒). The cause of Pruritus is divided into two. One is endogenous factors and the other is exogenous factors. The former are deficiency of blood(血虛), blood fever(血熱), wind-heat due to internal damage(內傷風熱), damp-heat in the liver and gallbladder(肝膽濕熱), endogenous wind stirring in the liver(肝風內動), deticiency syndrome of the spleen(脾虛), deficiency of Yin of the liver and kidneys(肝腎陰虛) and deficiency of the Penetration and Conception Vessels(衝任不足). The latter are wind-cold due to exogenous affection(外感風寒) and wind-heat due to exogenous affection(外感風寒). We report two stroke patients who complained of severe Pruritus They were diagnosed as having Xerotic Eczema by a dermatologist. We regarded their Pruritus as blood fever(血熱) and wind-heat(風熱) and prescribed Sopung-San to these patients. These patients showed significant improvement.

Purpose: This study was aimed for service to clinical data of physical therapy necessity of bone complication through analysis method of BMD (bone mineral density) used DEXA (dual energy X-ray absorptiometry) to their skeletal system for physical therapy assesement and intervention program in type II diabetic patients. Methods: Experimental group of 75 subjects and comparison group of 62 subjects were participated in type II diabetic patients(40-80 ages). BMD was measured by DEXA. BMD change of BMI score and BMD comparison of age and sex would be known. Results: This study was found that decreased BMD and increased osteopenea in type II diabetes. In particular, women were lower BMD and higher incidence of osteopenea than men. Men showed significant difference in normal group. Influence of type II diabetes was great on change of BMD in men. however, it showed no significant difference from normal group. Conclusion: it was found that skeletal system complication by type II diabetes had some relations. Because reduction of BMD had a great danger to induce trauma by fall or degenerative disease of system, evaluation of proper physical therapy for its prevention and improvement and intervention program are needed. In addition, it would be important to divide type II diabetic patients into osteopenea and osteoporosis changes of skeletal system at comprehensive aspect of physical therapy.

Due to the rapidly ageing population and low birth rates, most countries have faced with the problems of an ageing population. As a result, research into aging and the means to support an aging population has therefore become a priority for many governments around the world. Ambient Assisted Living(AAL) approach is the way to guarantee better life conditions for the aged and for monitoring their health conditions by the development of innovative technologies and services. AAL technologies can provide more safety for the elderly, offering emergency response mechanisms and fall detection solutions. Since the information transmitted in AAL systems is very personal, however, the security and privacy of such data are becoming important issues that must be dealt with. In this paper, we propose a Chameleon hash-based secure authentication protocol for AAL systems. The proposed authentication protocol not only supports several important security requirements needed by the AAL systems, but can also withstand various types of attacks. In addition, the security analysis results show that the proposed authentication protocol is more efficient and secure than the existing authentication protocols.

Patients with dementia or elderly patients who can not move at all by themselves are at a high risk of falls and bedsore due to lack of caregivers. In this paper, to solve this problem, we propose an algorithm to determine the patient's lying postures by discriminating the main body parts such as head, shoulders, and hips based on the pressure intensity sensed at regular intervals. A smart mat with a lattice structure in which a pressure sensor is arranged so that the body part can be discriminated irrespective of the physical characteristics has been implemented. It consists of two modules of $7{\times}7$ array size. Each module consists of 49 FSR-406 sensors and independently senses pressure. For each module, the body part corresponding to the upper body or the lower body is sequentially discriminated by using a pressure distribution such as a cumulative pressure sum using a filter. The proposed algorithm can identify five lying positions by examining the inclusion relationship between body parts belonging to layer-1 such as head, shoulder, and hip area.

Due to the recent outbreak of COVID-19 and an aging population and an increase in single-person households, the amount of time that household members spend doing various activities at home has increased significantly. In this study, we propose an algorithm for detecting anomalies in members of single-person households, including the elderly, based on the results of human movement and fall detection using an image sensor algorithm through home CCTV, an activity sensor algorithm using an acceleration sensor built into a smartphone, and a 2D LiDAR sensor-based LiDAR sensor algorithm. However, each single sensor-based algorithm has a disadvantage in that it is difficult to detect anomalies in a specific situation due to the limitations of the sensor. Accordingly, rather than using only a single sensor-based algorithm, we developed a fusion method that combines each algorithm to detect anomalies in various situations. We evaluated the performance of algorithms through the data collected by each sensor, and show that even in situations where only one algorithm cannot be used to detect accurate anomaly event through certain scenarios we can complement each other to efficiently detect accurate anomaly event.

Background: This study investigated the effects of face-to-face and non-face-to-face McKenzie exercises and elastic band strengthening exercises on falls and fitness in older adults. Methods: A total of 44 subjects were divided into a face-to-face group (FG; n=22) and a non-face-to-face group (NFG; n=22) who met older adults. Both groups used McKenzie exercises and strength training with elastic bands The fall efficacy scale (K-FES) and glycosylated hemoglobin (HbA1c) Pro were used to compare the senior fitness test (SFT). Results: No significant differences were detected between the two groups before the intervention; however, a significant difference was noted in the K-FES scores after the intervention. The change in HbA1c after the intervention was not statistically significant in the FG or the NFG, and no significant difference was detected between the two groups. The change in lower limb muscle strength in the elderly physical fitness test showed no significant difference between the two groups before or after the intervention. The change in upper limb flexibility after the intervention was not significantly different in the FG or NFG, indicating no significant difference between the two groups. The change in the 3-meter round-trip test after the intervention was significantly different in both the FG and NFG groups, but the difference between the groups was not statistically significant. The change in the grip strength test of the dominant hand showed no significant difference after the intervention in the FG or the NFG, and the difference between the FG and NFG groups was not statistically significant. The dominant foot external standing after the intervention was significantly improved in the FG, but no significant difference was detected in the NFG, and the difference between the two groups was not statistically significant. Conclusion: The study findings revealed that FG and NFG McKenzie exercises and elastic band strengthen exercises were equally effective at preventing falls and improving fitness in older adults.

Objective: This study aimed to report the relationship between walking activity and perceived physical activity barriers after classifying the age group(≤64, 65-74, ≥75). Methods: The subjects were conducted on 1500 residents of two areas, and the walking activity was defined as five or more times a week, 10 minutes or more at a time, and 30 minutes or more per day. Perceived physical activity barriers were lack of time, lack of social support, lack of energy, lack of willpower, and fear of falling. Results: In the group under 64 year, the lack of time (exp(B)=0.819, p=0.002) and the lack of willpower (exp(B)=0.656, p<0.001) were significantly associated. In the 65-74 year old group, the lack of willpower (exp(B)=0.714, p<0.001) and fear of falling (exp(B)=0.787, p=0.003) were a significant association. In the group aged 75 years and over, lack ofwill power (exp(B)=0.734, p<0.001) and fear of falling (exp(B)=0.807, p=0.003) were significantly associated. Conclusion: In order to solve the lack of willpower and lack of time, a walking activity should be performed together at a certain time in the village, and the elderly in the late ages should reduce the fear of falling by performing a fall prevention exercise in parallel.
