The purpose of this study was to identify the effects of visual programs on job stress and burnout in emergency room nurses. This study used a nonequivalent control group pretest-posttest design. There were 26 participants in the experimental group and 27 in the control group. Data collection took place from December 12, 2017 to February 17, 2018. The program comprised eight weekly 120-minutes sessions, which included understanding and assessing job stress and burnout. Data were analyzed using the Chi-square test, paired t-test, and independent t-test. As a result, levels of job stress (t=-20.09, p<.001) and burnout (t=-22.31, p<.001) decreased significantly in the experimental group. The results suggest that the Visual Media Program could be an effective strategy for reducing job stress and burnout. Therefore, it is deemed a useful intervention for improving the quality of nursing care provided in emergency rooms.

Recently, advance in technology have increased the importance of visual inspection in semiconductor inspection areas. In PCB visual inspection, accurate line estimation is critical to the accuracy of the entire process, since it is utilized in preprocessing steps such as calibration and alignment. We propose a line estimation method that is differently weighted for the line candidates using a histogram of gradient information, when the position of the initial approximate corner points is known. Using the obtained line equation of the outline, corner points can be calculated accurately. The proposed method is compared with the existing method in terms of the accuracy of the detected corner points. The proposed method accurately detects corner points even when the existing method fails. For high-resolution frames of 3.5mega-pixels, the proposed method is performed in 89.01ms.

Although many children with cerebral palsy have problems with their eye movements available data on its intervention is minimal. The purpose of the study was to determine the effectiveness of the postural movement normalization and eye movement program on the oculomotor ability of children with cerebral palsy. Twenty-four children with cerebral palsy (12 male and 12 female), aged between 10 and 12, were invited to partake in this study. The subjects were randomly allocated to two groups: an experimental group received the postural movement normalization and eye movement program and a control group which received conventional therapy without the eye movement program. Each subject received intervention three times a week for twelve weeks. The final measurement was the ocular motor computerized test before and after treatment sessions through an independent assessor. Differences between the experimental group and control group were determined by assessing changes in oculomotor ability using analysis of covariance (ANCOVA). The changes of visual fixation (p<.01), saccadic eye movement (p<.01) and pursuit eye movement (p<.01) were significantly higher in the experimental group than in the control group. These results show that the postural movement normalization and eye movement program may be helpful to treat children with cerebral palsy who lose normal physical and eye movement.

Purpose: The study investigated the effect of combined balance exercise using visual feedback and balance pads in rehabilitation of chronic stroke patients. Methods: The participants were 30 patients diagnosed with stroke who met the study selection criteria. Participants were randomly divided into 3 groups of 10: a balance pad exercise (BPE) group, a visual feedback exercise (VFE) group, and a combined balance exercise (CBE) group. All three groups engaged in 30 minutes of exercise, 3 times per week, for 6 weeks. Results: Pre-test and post-test results were analyzed using the functional reach test (FRT), the Berg balance scale (BBS), the timed up & go test (TUG), and the Korean version of the activities-specific balance confidence (K-ABC) scale. The study yielded the following results. Pre- and post-program FRT measures showed significant differences between the BPE and CBE groups (p < 0.05). BBS, TUG, and K-ABC scores showed clear differences in all three groups. Secondly, the CBE group and the BPE group a differed significantly on the BBS before and after the 6-week program (p < 0.05). Finally, the CBE group and the VFE group differed significantly on the BBS before and after the 6-week program (p < 0.05). Conclusion: The study results indicate that combined balance exercise improves balance more effectively than the balance pad and visual feedback exercises. This finding should help to improve rehabilitation in the future.

Purpose : The purpose of this study was to examine the effects of applying occupational therapy that uses motion recognition on the physical self-efficacy, visual-motor integration ability, and play skills of children who have neurodevelopmental disorder before and after treatment. Methods : This The study chose 16 children with neurodevelopmental disorder as research subjects who were randomly and evenly allocated into an experimental group and a control group. The experiment followed a pretest-posttest design. As an intervention, the experimental group received motion recognition-based occupational therapy and a separate sensory integration program. The control group only participated in the separate sensory integration program. The eight-week experiment duration included 24 intervention sessions where the a 50-minute session was implemented three times a week for eight weeks. To compare the physical self-efficacy, visual-motor integration ability, and play skills before and after the intervention, measurement tools including the Physical self efficacy, Beery VMI-6, and Penn interactive peer play scale were used. All measured variables were analyzed and expressed as mean, standard deviation and percentage. Results : The motion recognition-based occupational therapy demonstrated a significant effect on improving the physical self-efficacy, visual-motor integration ability, and play skills of the experimental group. The intervention also caused a significant difference between the experimental group and control group in terms of the physical self-efficacy, visual-motor integration ability, and play skills. Conclusion : We confirmed the possibility motion recognition-based occupational therapy could be effective in improving the physical self-efficacy, visual-motor integration ability, and play skills for patients who have neurodevelopmental disorder. Based on the study result, further future studies are expected based on this study result that prove the application effect of the motion recognition-based occupational therapy using disabled and non- disabled children as subjects are expected in the future.

The land use type of Korea is high-density. So, the image classification using coarse resolution satellite image may not provide land cover classification results as good as expected. The purpose of this paper is to compare the result of visual interpretation with that of digital image classification of 20 m resolution SPOT satellite image at Kwangju-eup, Kyunggi-do, Korea. Classes are forest, cultivated field, pasture, water and residential area, which are clearly discriminated in visual interpretation. Maximum likelihood classifier was used for digital image classification. Accuracy assessment was done by comparing each classification result with ground truth data obtained from field checking. The classification result from the visual interpretation presented an total accuracy 9.23 percent higher than that of the digital image classification. This proves the importance of visual interpretation for the area with high density land use like the study site in Korea.
