Purpose : This study aims to evaluate the correlation of cognitive function, activities of daily living (ADL), and driving performance in stroke hemiplegic patients residing in Korea. Methods : Subjects of the study were 18 stroke hemiplegic patients admitted to hospitals situated in Seoul. A clock drawing test (CDT), a modified Barthel index (MBI), and a virtual reality driving simulator (Eca faros-driving simulator) were used to examine their cognitive function, their ADL ability, and their driving skills, respectively. Results : Driving skills of stroke hemiplegic patients were shown to be associated with the CDT evaluation tool (r=-.777) (p<.001), but they were found to have any correlation with MBI (r=-.022) (p>.05). Additionally, an individual's CDT showed that the driving simulator evaluation result (pass/fail) could be discriminated with a sensitivity of 100.0 %, a specificity of 40.0 %, and an accuracy of 66.7 %. The result confirmed that the CDT is a useful evaluation tool for screening driving ability in people with stroke. But the MBI did not show any significant results (sensitivity of 62.5 %, specificity of 40.0 %, and predicted the results of the simulator with 50.0 % of accuracy) (p>.05). Conclusion : This study shows that cognitive function influences the driving performance in people with stroke. Driving skills of stroke hemiplegic patients are seen to be highly related to CDT. In the field of driving rehabilitation, these findings could be useful for evaluating driving skills relating to CDT. Furthermore, the study results will set a guideline for domestic occupational therapists to use the evaluation tool for assessing driving abilities in people with stroke.

Objective : To investigate the correlation between relationship ability and ADL performance ability of patients with TBI. Methods : This study was carried out from March 2012 to April 2012 with 20 patients with TBI. Relationship ability assessed using Relationship Change Scale(RCS), ADL performance ability assessed using Functional Independence Measure(FIM). Results : The RCS showed a high level of correlation with marital status and duration of illness. The RCS showed a high level of correlation with the FIM total score and the FIM cognition area. However the RCS did not show a correlation with the FIM motor area. Conclusions : Functional disability of social cognition is a factor that disturbs rehabilitation after TBI and it has a negative influence on the relationship in ADL. If accurate evaluation and treatment on relationship ability after TBI are carried out side by side from the initial stages of onset, we could expect more patients to improve their social cognition and ADL performance ability.

Objective : The purpose of this study was to compare with the effects of driving simulator and Dynavision training after stroke through the test of cognitive ability and driving performance. Methods : Twenty-one stroke patients were randomly classified to the driving simulator training group (N=11) and Dynavision training group (N=10), and were carried out respectively training for 15 times. The driving performances was measured by the driving simulator test, and cognitive-perceptive abilities was measured by the DriveABLE Cognitive Assessment Tool, Trail Making Test-A, Trail Making Test-B and Mini Mental State Examination-K. Results : The driving simulator training group showed significant changes in all cognitive tests and most of driving performances. The Dynavision training group also showed significant changes in all cognitive tests except for Trail Making Test-A and some driving performances. The significant differences on both groups were found regarding the estimated degree of results on the on-road evaluation, the number of off road accidents and collisions. In addition, the causal influence of the two training methods on these variables was analyzed to be more than 20%. Conclusion : The driving simulator and Dynavision training were found to be effective intervention in the driving rehabilitation after stroke. In particular, it was confirmed that the driving simulator is an effective training to improve overall driving ability of stroke patients. In addition, the difference in training effect between the two training methods was found to be more than 20%.

Objectives: This study assessed the status of domestic industrial hygiene laboratories using data from on-site investigation for revision of quality control systems in 2012-2013. Methods: The target laboratories were 60 industrial hygiene laboratories chosen by random selection and nationwide distribution which had participated in on-site investigations for revision of quality control systems from March 2012 to August 2013. The investigation was performed on-site following standard quality control procedures. The score between each group was compared using Mann-Whitney and Kruskal-Wallis tests, and the correlation between analytical career, sex, academic major of analyst and score of analytical performance was expressed as Spearman's rank correlation coefficient. Results: The assessment revealed that the items to be improved, in sequence, were effort at staff training (score 65.5), ability to calculate data (score 73.4), establishment of internal quality control guidelines (score 75.7), laboratory facilities (score 77.1), degree of understanding and skill at gas chromatography (score 77.1). Analysis performance showed a positive correlation with career of analyst (r=0.56, p<0.01). Conclusions: The practice of on-site investigation for quality control systems showed the current status of industrial hygiene laboratories in the first trial. There were many laboratories which needed improvement and development of analytical systems. This assessment can provide information for the systematic operation and improvement of facilities at each laboratory. Further practice of this investigation will lead to a proficiency testing and accreditation system for autonomous quality control as is the practice in many countries, rather than mandatory practice by legal regulation.

Conventional occupational therapy (OT) is conducted under the observation of an occupational therapist, and there are limitations in measuring and analyzing details such as degree of hand tremor and movement tendency, so this important information may be lost. It is therefore difficult to identify quantitative performance indicators, and the presence of observers during performance sometimes makes the subjects feel that they have to achieve good results. In this study, by using the Unity3D and artificial intelligence (AI) speaker, we propose a system that allows the subjects to steadily use it by themselves and helps the occupational therapist objectively evaluate through quantitative data. This system is based on the OT of the sensory integration approach. And the purpose of this system is to improve children's activities of daily living by providing various feedback to induce sensory integration, which allows them to develop the ability to effectively use their bodies. A dynamic OT cognitive assessment tool for children used in clinical practice was implemented in Unity3D to create an OT environment of virtual space. The Leap Motion Controller allows users to track and record hand motion data in real time. Occupational therapists can control the user's performance environment remotely by connecting Unity3D and AI speaker. The experiment with the conventional OT tool and the system we proposed was conducted. As a result, it was found that when the system was performed without an observer, users can perform spontaneously and several times feeling ease and active mind.

The purpose of this study was to investigate the changes of the activities of daily living (ADL) by the motor learning program for upper extremity in stroke patients. The subjects were sixty-two members who were treated at the department of occupational therapy. The ADL were measured with Functional Independence Measure (FIM). The result's were as fol1ows; 1. The ability to perform daily activities after treatment was significantly increased independent of age, gender, cause, affected side and speech disability (p<.01). The differences between the pre-treatment and the post-treatment was no significant correlation to sex, cause, affected side and duration of treatment, but the speech disability was significant. Therefore the pre-treatment scores and post-treatment scores were significantly different. 2. The variation of the pre-treatment and the post-treatment in the detail item to the performance of daily life of the stroke patients through the upper extremity motor learning program was significantly increased in self-care, sphincter control, locomotion, mobility, communication and social cognition (p<.01) Consequently, The motor learning program for upper extremity significantly improved the performance level of all ADL areas in stroke patients.

Purpose: In this study, we tried to determine the effect of upper extremity training such as functional reaching on improved trunk control and ADL performance in post-stroke hemiplegic patients. Methods: We randomly selected 11 stroke patients in the hospital, who had a problem with the upper extremity, trunk and ADL performance. The patients were divided into the conservative training group and the functional reaching training group. We applied general occupational therapy only in the conservative training group whereas we applied upper extremity training with a focus on functional reaching in the functional reaching training group. To compare the two groups we used several assessment tools such as Modified Barthel Index (MBI), total Trunk Impairment Scale (TIS), static TIS, dynamic TIS and coordinative TIS. Results: The results obtained were as follows: (1) In the functional reaching training group, there was a statistically significant difference in the total TIS score, dynamic TIS score, and MBI. (2) We compared the results obtained before training with the changes in the results obtained after training and found that there was a relation between the assessment outcomes. Especially, static TIS score showed a relation in both groups. Conclusion: Functional reaching training influenced both the trunk control and ADL performance. Especially, the functional reaching training group demonstrated better static trunk control ability than the conservative treatment group.
