This paper describes a passive SID sensor tag that provide physical security functions based on a sensor interface module. It elementarily consists of a serial I/O interface, control module, and sensor module. In this paper, it show tamper-proof security functions by comparison and encryption with the sensor signal data using the physical resistors. The passive SID sensor tag can be realized by the real time management for the safety, forgery, and so on. The proposed SID tag embedded with a sensor module is expected to find wide physical security applications.

Purpose: This study aimed to determine the effects of sensory feedback training of the ankle with visuoperceptual stimulation on static balance and gait functions in patients with chronic post-stroke hemiparesis. Methods: This study included 16 patients with chronic post-stroke hemiparesis. The subjects were randomly assigned toeither the experimental group (EG) or the control group (CG), with 8 subjects in each group. All the subjects received a routine physical therapy. The EG subjects received a 30-min sensory feedback training for the foot and ankle with visuoperceptual stimulation by using Tetrax Portable Multiple System. This training was conducted 3 times a week for 4 weeks. The scores of balance ability, timed up and go (TUG), and dynamic gait index (DGI) were assessed before and after the intervention. Results: In the EG, the scores of static balance, TUG, and DGI obtained afterthe intervention significantly differed from those obtained before the intervention (p<0.05). Further, in the EG, a significant difference was noted in the rate of change of all the variables when compared with those of the CG (p<0.05). However, in the CG, post-intervention score were only significantly different for DGI. Conclusion: Our findings indicate that the sensory feedback training with visuoperceptual stimulation improves balance and gait functions of patients with chronic post-stroke hemiparesis. Further studies are needed to generalize the results of this study.

Background: A cancer survivor is defined as anyone who has been diagnosed with cancer, from the time of diagnosis through the rest of their life. The purpose of this study was to examine whether physical functions, health-related outcomes, nutritional status and blood markers in community-dwelling cancer survivors aged 75 years and older are different from those who do not have cancer Materials and Methods: Two hundred seventy-five participants were asked by physicians, nurses, and physical therapists, questions regarding cancer history in a face-to-face interview. Data were collected for demographic information, physical functions, such as handgrip strength, knee extension power, abdominal muscle strength, static standing balance, walking speed and the timed-up-and-go test, health-related outcomes, nutritional status, and blood markers. The measured parameters of survivor diagnosed with cancer were compared with those without a history of cancer. Results: Thirty-seven older adults were previously diagnosed with cancer. Female cancer survivors had lower knee extension power (p<0.05), abdominal muscle strength (p<0.05), walking speed (p<0.05), timed-up-and-go test score (p<0.05), and time to spend on walking per day (p<0.05) than older women without a history of cancer. In men, none of the measured parameters were significantly different between cancer survivors and older men with no history of cancer. Conclusions: The present study shows that partial physical function of women cancer survivors aged 75 years and older differs from that in women with no history of cancer.

The purpose of this study was to examine the effect of the upper limb nerve mobilization (ULNM) on functional recovery of upper extremity in hemiplegic patients following stroke. Twenty patients who had functional impairment on upper extremity were participated. Subjects were randomly divided into two groups: Control group (n=10) received traditional physical therapy only for 4 weeks; Experimental group (n=10) received ULNM treatment along with traditional physical therapy for the same period. Upper extremity functions were assessed by manual muscle test (MMT), modified Ashworth scale (MAS), and Fugl-Meyer assessment (FMA) before and after the treatment. In both experimental and control group, upper extremity functions were significantly improved in MMT (p<.01) and FMA (p<.01), however only experimental group showed significant improvement in FMA after the treatment (p<.05). Moreover, experimental group showed significantly greater improvement than control group in MMT (p<.05), MAS (p<.05), and FMA (p<.05). We conclude that the upper extremity functions is a useful additional therapeutic technique for the effective treatment of upper extremity deficits in hemiplegic patients.

PURPOSE: This study compared the effects of computer-based and virtual reality-based cognitive rehabilitation programs on the cognitive function, upper limb function, activities of daily living, and their impact on the prefrontal cortex in convalescent stroke patients. METHODS: Ten recovering stroke patients were assessed for their cognitive function, upper limb function, and daily living activities using the Neurobehavioral Cognitive Status Examination, the Korean version of the Fugl-Meyer Assessment, and the Korean version of the Modified Barthel Index. The prefrontal cortex activity was measured with functional Near Infrared Spectroscopy. The virtual reality-based cognitive rehabilitation group utilized a program of daily living activities delivered via a laptop and Oculus Rift. The computer-based cognitive rehabilitation group performed various cognitive tasks on an all-in-one PC. Both groups underwent cognitive rehabilitation training for 30 minutes per day, three times a week, for six weeks, with identical conventional rehabilitation therapies in the hospital. RESULTS: Both programs positively impacted the cognitive and physical functions. On the other hand, the virtual reality-based cognitive rehabilitation program had a larger influence on improving the cognitive and physical functions of convalescing stroke patients. CONCLUSION: The virtual reality program suggests its potential to enhance cognitive and physical functions in convalescent stroke patients through increased engagement, focus, real-time feedback, and game elements, making it a promising rehabilitation approach.

The Goal of this study was to assess the effect of aerobic exercise on cognitive function of elderly people. The participants' cognitive functions were measured before exercise. Exercise was practiced three times a week for nine weeks. The aerobic exercises consisted of warm-up exercises for five minutes followed by cycling for 30 minutes. The exercise intensity was set to 65%~75% of the intensity for the maximum heart rate(220-age). The control group did not perform any exercises. The subjects' cognitive functions were measured nine weeks later. In the aerobic exercise group, between before and after the exercises, significant increases appeared in total K-MMSE scores and scores of some sub items comprising memory registration, concentration and calculation abilities but not in other items. In the control group, no significant differences appeared in any items between before and after the experiment. In a comparison between the aerobic exercise group and the control group, significant differences appeared in total K-MMSE scores and scores of two sub items comprising concentration and calculation abilities but not in other items(p<.05). Aerobic exercises were effective in the improvement of cognitive functions and among sub items of cognitive functions, concentration and calculating abilities were improved. Aerobic exercises performed by elderly persons are considered to be effective in improving cognitive functions.

Although the physical therapy of both East and West has been based on an identical philosophy, they have had their own therapy with difference in its form and pattern. In general, cupping is used to diagnose and treat viscera by means of acupuncture point, and myofascial release is also used for both diagnosis and orthopedic treatment on the basis of trigger point and myofascial however, when they have a lot of identical facts such as using both mental and physical aspects of human beings for treatment, keeping nervous action balanced, and recovering depressed nervous functions and relieving the pain. In addition. their identical fact includes that they tend to treat patients by using symptoms and reaction shown in their skin, and that both East and West try to consider myofascia as an integrated totality and as a unified body of organic functions with correlations. Among the principles of myofascial release, recently, it has been very identical that stimulus given to the skin results in synapse to sympathetic nerve through dosal horn cell has an effect on viscera, and that cupping is sued for diagnosis and treatment of viscera. It is required, therefore, to continue to carry out studying on this field.

This study performed a virtual reality exercise program for self-back pain control of industrial workers with chronic back pain and analysed their physical function and health-related quality of life relating to industrial chronic back pain. The subjects of the study were thirty chronic back pain patients working for K company and were divided into Nintendo Wii Sports Group made of 15 subjects and Physical Therapy Group made of 15. As variables for physical functions, back strength, flexibility, balance and pain were measured and for the health-related quality of life, SF-36 of each group was measured before and after the exercise program. To compare differences before and after the program, a paired t-test was used and to compare differences between both groups, an independent samples t-test was used. As a result of the test, it was discovered that balance and pain of the both groups were improved statistically significantly. Physical functions of the Nintendo Wii Sports Group were improved statistically significantly in comparison with those of the Physical Therapy Group. The health-related quality of life was improved statistically significantly only for the Nintendo Wii Sports Group. In conclusion, it is suggested that as the virtual reality exercise program had a positive influence on chronic back pain of industrial workers, it should be considered as a home exercise program for back pain control.
