Rehabilitation assistive devices not only assist the rehabilitation therapy and daily life of the disabled and the elderly, but also assist the labor of their caregivers, so various functions are required to improve their quality of life. In this study, a design method considering its practicality is introduced for an active rehabilitation assistive device that can perform both standing and walking assistance by driving various actuators. For this purpose, the force required to assist standing was calculated using statics with the body segmentation method. Also, the overturning stability of the device was verified for various physical conditions and postures. The actuator in the active rehabilitation assistive device was operated by a patient using a graphical user interface in an embedded computer and a touch panel for easy usage. The detailed design was performed for implementation through the help of 3D-CAD and the finite element analysis, and a prototype was produced. Finally, it was proven that the design goal was satisfied by experimental validation.

The aim of this study was to investigate the effects of computer-based cognitive rehabilitation and traditional cognitive training on the working memory and executive function of patients with mild traumatic brain injury. The sample consisted of 20 patients with mild traumatic brain injury who had received rehabilitation treatment in a rehabilitation unit. The subjects were assigned to either the experimental (n = 10) or control group (n = 10). The experimental group received computer-based cognitive rehabilitation and traditional cognitive training for 60 minutes, whereas the control group received only traditional cognitive training for 60 minutes. Both the groups received their respective interventions for 60 minutes a day and 5 times per week across a period of 4 weeks. Working memory and executive function were assessed using the digit span test (forward and backward), visual memory 1 and 2 of the Motor-free Visual Perception Test-3, trail making test, and Stroop test (A and B) both before and after the intervention. The experimental group showed a significantly greater improvement in visual memory and performance on the Stroop test A than the control group. These findings suggest that computer-based cognitive rehabilitation and traditional cognitive training are more effective in promoting positive changes in the working memory and executive function of individuals with mild traumatic brain injury than traditional cognitive training.

This study selected a total of 19 studies using databases of PubMed, SAGE Journal, and Wiley Online Library from 2000 to 2019 to find out about vocational rehabilitation of patients with schizophrenia in the area of overseas occupational therapy. First, the quality level of the study was all Level I. Second, the diagnosis for participants of the studies other than schizophrenia had the most schizoaffective disorder. Third, by types of interventions, 11 papers, the largest, were about social skills and cognitive rehabilitation training plus supported employment, followed by 4 about supported employment and 3 about social skills and cognitive rehabilitation training, 1 about other vocational approaches. Regarding studies showing effects in the employment rate by interventions type following three types of employment, as the most effective of studies, they were social skills and cognitive rehabilitation training plus support employment in competitive employment, social skills and cognitive rehabilitation training in non-competitive employment, and support employment in paid employment. Fifth, looking at the studies trend in the last 5 years, the most studies were social skills and cognitive rehabilitation training plus supported employment. Since this study classified the types and effects of vocational rehabilitation for patients with schizophrenia based on previous overseas studies, it is hoped that this study will be provided as basic data for understanding vocational rehabilitation of schizophrenic patients and applying them in domestic clinical settings.

Magnetic sensors and actuators have been widely used in industry and medical fields. Integrated systems based on sensors and actuators are defined as mechatronics that is the general combination of mechanics and electronics. Recently, magnetic wireless sensors and actuators have been developed and used at a systematic level. In particular, their mechanisms depend on magnetic, such as magnetic material and physical phenomena. However, their research boundary has not been clear. Researchers talk of magnetic micro-robots, magnetic actuators and sensors. Therefore, a new and correct definition is required. In this study, we introduce the advanced and extended concept of mechatronics, which is a magneto-mechantronics for biomedical and rehabilitation. Among various applications, we focused on wireless pump and sensing system for blood vessel rehabilitation and local motion capture, respectively.

In recent years the research and development about the new material proceeds rapidly and actively in building industry. We are concerned with high-strength concrete as a new material. As the building structure becomes bigger, higher and more specialized, so does the demand of material and member with high strength for building expands greatly. In the future, we will quite need to research repair and rehabilitation to make high strength concrete structural building for our safe. So, I did an study on carbon fiber sheet rehabilitation(CFSR) of reinforced high strength concrete beams. The carbon fiber reinforced plastic(CFRP) bonding method is widely used for reinforcing the existing concrete structure among the various methods. The test results indicate that CFS is very effective for strengthening the damaged beams and controlling deflections of the repaired beams. When carbon fiber sheet rehabilitation of reinforced high strength concrete beams happened diagonal crack, the increase in the number of CFS layer didn't effect the increase in strength of beams. Also, by changing the CFS stick position gave diversified ultimate load in CFSR beams.

As a means of treatment for people with disabilities, there is a growing interest in horse riding. Horse riding improves physical conditions such as muscles, joints, and cardiopulmonary function, alleviates tension, and encourages confidence through large animals such as horses. The various therapeutic effects of therapeutic horse riding have been recognized by many medical professionals, including the American Occupational Therapy and Physical Therapy Association. On the other hand, in Korea, there is not yet a scientific basis for the therapeutic effects of specific diseases or clinical treatments. The purpose of this study was to investigate the possibility of rehabilitation related professional worker's therapeutic horse riding. Recognition and use experience of therapeutic horse riding were generally low, but doctors who wanted to use it when the expectation of effectiveness and therapeutic horse riding education were assumed were relatively high. Based on these results, it can be confirmed that the therapeutic horse riding will be recognized as a clinical treatment method in the future.
