Introduction : This study reviews the main areas of cognitive rehabilitation including executive dysfunction, memory dysfunction, perceptual dysfunction, attention deficit, and dysfunctions in activities of daily living in order to apply to the adaptation of occupational therapy. Body : Cognition programs based on the virtual reality are being used not only to evaluate but to train the overall components of human's cognition. Because the cognitive program is concentrating on the real environment, it is known to bring a remarkable transitional effect to the actual environment, compared to the basic computer-based evaluation and training. Applying virtual reality to the rehabilitation program can develop and advance the high technology and can result in a major effect on the innovative treatment technology. Conclusions : In this process, virtual reality is expected to be researched more in the near future. Particularly in the cognitive realm, it is imperative for researchers to pay attention to the improved transitional effect of the virtual reality toward the actual environment, rather than the already existing method of evaluations. Therefore, application of the virtual reality for the cognitive training should be researched for various types of subjects in the diverse aspects of congnitive function. Application of the virtual reality in the cognitive function has its unlimited potential, thus the rehabilitation program integrated with not only evaluation but training and education is expected extensively in the future.

The purpose of this study was to investigate the effect of white noise on memory and attention of local community elderly during computer-based cognitive rehabilitation program(COMCOG). 30 elderly subjects were recruited and conveniently allocated into experimental and control group. Experimental group subjects carried out COMCOG with white noise. Control group subjects received COMCOG for 30 minutes, 3 times per week for 6 weeks. Neurocognitive funtion test(CNT) were used to evaluate memory and attention during pre and post. The most CNT outcome at post was significantly improved than the pre outcome in the both group(p<.05). And the experimental group showed significantly difference from control group(p<.05). The result of this study show that the COMCOG with white noise may be appropriate for improving memory and attention in elderly. This will enable the application of COMCOG with white noise in cognitive rehabilitation therapy of local elderly and it will help guide the selection of the therapist as one therapeutic basis

The purpose of this study is to investigate the effects of Korean computer-based cognitive rehabilitation program (CoTras) on frontal-executive functions in patients with traumatic brain injury (TBI). This study was performed at C hospital in Changwon, Gyeongsangnam-do, Korea from August 2013 to March 2014. Ten patients with TBI were randomly divided into two groups. The experimental group had been given CoTras once a day, five times a week for four weeks, whereas the control group had performed self-cognitive training under the same conditions. To verify the effect of intervention, the following executive function measures were used: Korean Montreal Cognitive Assessment (K-MoCA), Executive Clock Drawing Test (ECDT), Trail Making Test (TMT), Rey-Complex Figure Test (RCFT). Intervention group showed significant increase in K-MoCA, TMT, RCFT-delayed recall (p<.05). However, control group showed no significant change in any test. There was significant difference of changed scores (post test-pre test) between two groups in K-MoCA, TMT and RCFT-delayed recall (p<.05). This study showed that CoTras is effective to improve frontal-executive functions in patients with traumatic brain injury.

Objective: This study aims to recognize the risk of current traffic systems and to investigate a method to decrease risk by doing exercise using an elastic-band and cognitive rehabilitation. Background: The existing traffic system usually focuses on the ordinary citizens, which may not be appropriate to the elderly. It may affect the cognition and walking speed of the elderly. This study tries to examine whether cognition and muscle training is appropriate to improve their vulnerability. Therefore this study will provide human ergonomics - based basic data in relation to the elderly to identify the risk of current signal system and to mitigate the risk. Method: A total of 30 elderly participants were divided into two groups: experimental and control groups. Experimental group (n=15) was trained to strengthen their muscles and to promote cognition, whereas control group (n=15) was not. The training was conducted twice a week for three weeks. To strengthen muscles, a yellow colored elastic-band was used, and a computer program for cognitive rehabilitation was used to develop cognition. In the experimental group, there were significant differences between pre and post exercises However, the control group didn't show any significant difference. The increase in cognition and walking speed was found in the experimental group, whereas there were no differences in the control group. Statistically there was no significant difference between the two groups. Results: The results of this study show that the exercise program using the elastic-band gave a positive effect on gait training thanks to the development of muscle power and balance. Conclusion: This study did not show any statistical difference or significant differences between the two groups, since time was restricted, we believe. Application: The results of the walking speed will help to prevent traffic collision.

Up to now, several tools to evaluate visual perception tests have been introduced for different purposes. However, they were mostly manual tools, paper books in which the therapists would turn the pages while working together with patients. This paper discusses a potential plan to develop motor-free visual perception test software for Korean patients with brain injury, and to construct a centralized database for their evaluated data in a client/server environment. Through its development, we eventually hope to achieve effective management of the data for better understanding of patients' visual perceptual skills and the standardization of the evaluation for Korean patients. With the help of the computerized environment, we also expect some advantages such as acquisition of reliable results from patients with brain injury, automation for storing and accessing patients' data, construction of the patients' database and the management of a vast amount of the data within it and the provision of a foundation to promote further development of various perceptual-cognitive rehabilitation programs.

The result of analyzing the cognitive reaction due to the color environment has been applied to various filed especially in medical field. Moreover, the study about the identification of patient's condition and examination the brain activity by collecting the bio-signal based on the color environment is being actively conducted. Even though, there were a variety of experiments by convention the color environment using a light or LED color, it still has a problem that affects the psychological information. Therefore, our proposed system using a HMD (Head Mounting display) to provide a completed color environment condition. This system uses the BMS(Biomedical System) to collect the biometric information which responds to the specific color condition and the human body response information can be measured by the development the Memory and Attention test on Mobile phone. The collection of Biometric information includes electro cardiogram(ECG), respiration, oxygen saturation (Sp02), Bio-impedance, blood pressure will store in the database. In addition, we can verify the result of the human body reaction in the color environment by Memory and Attention application. By utilizing the reaction of the human body information that is collected thought the proposed system, we can analyze the correlation between the physiological information and the color environment. And we also expect that this system can apply to the medical diagnosis and treatment. For future work, we will expand the system for prediction and treatment of Alzheimer disease by analyzing the visualization data through the proposed system. We will also do evaluation on the effectiveness of the system for using in the rehabilitation program.
