In this study, diagnostic algorithm was suggested to diagnose quantitatively the degree of the stress urinary incontinence. The bio-signal measurement system was developed to measure the contraction pressure of the pelvic floor muscle and diagnostic parameters were drawn out by analyzing the contraction pressure data. Statistical evaluations were done to classify the diagnositc parameters by order that relationship is high. The diagnostic algorithm that was able to diagnose degree of the urinary incontinence as quantitatively was realized from the high relationship parameters.

During the electromyographic evaluation, the presence and site of lession may be predicted by a detection of denervation potentials such as fibrllation potentials or positive sharp waves in the group of muscles. Currently, clinicians diagnose the neuropathy by detecting fibrillation potentials during EMG tests, and sometimes it is not easy to distinguish between denervation potentials and endplate spikes. The purpose of this study was to find statistically significant parameters for the quantitative distinction between denervation potentials and endplate spikes. Endplate spikes and denervation potentials from the EDB muscle of 10 patients were extracted. Also, EMG signals were classified by experienced clinicians, and were collected using a 12 bit ADC with a sampling rate of 20KHz for the duration of 400msec. In order to find statistically significant parameters, positive and negative peaks were used for analysis. As a results, standard deviation of the endplate spikes and denervation potentials showed more significant difference than others specially for the positive sharp waves. It was concluded that the results of this study could be used to develope an automated system of a EMG analysis.

WTO/TBT requires that, for technical regulations affecting trade, technical regulatory requirements must be specified where possible in terms of performance rather than design or descriptive characteristics. The movement which made "performance" a keyword in landscape architecture was activated in Japan, one of the leading counties in performance-based regulatory system(PBRS). The Japanese recent movement of systematization activity on performance-based standards and specifications was reviewed and operational applications for performance-based regulatory system in South Korea are summarized as follows: 1. The establishment of performance standards that can be properly evaluated by assessment indicators is necessary in cases when quantitative evaluation is difficult. 2. As a preparation for PBRS, a brief procurement system by technical proposal for the landscape design and construction is necessary. 3. As a preparation for PBRS, activation of an environmental performance evaluation on experimental construction is necessary. 4. As a preparation for PBRS, a certification system of environmental performance on various landscape construction methods is necessary. 5. The Private Finance Initiative Project is the most similar to PBRS therefore, activation of the Private Finance Initiative Project is necessary in landscape architecture projects for park rehabilitation.

Purpose: Cancer patients are at a higher risk of being unemployed or facing difficulty in returning to work (RTW) than individuals without health concerns. The aim of this study is to identify and describe interventions developed specifically to assist cancer patients to RTW after treatment. Methods: A comprehensive search was conducted from September to October 2018 in different international databases: PubMed, Medline, and Embase. Studies using qualitative, quantitative, or mixed designs were included if they satisfied the following criteria: (a) described an intervention to assist cancer patients to RTW during or after treatment; (b) conducted on patients aged 18 and over and diagnosed with cancer; (c) written in English; (d) published in peer-reviewed journals. Results: Fourteen studies met the inclusion criteria. Counseling with physical activity intervention, behavioral training to reduce fatigue, and multi-disciplinary rehabilitation programs were found to be effective. Conclusion: Interventions adopting a multidisciplinary approach were effective for RTW in cancer patients. This literature review emphasizes the need for more tailored interventions based on survivors' needs and characteristics in the RTW field.

Purpose: This study was conducted in order to evaluate the quantitative effectiveness of region of interest (ROI) setting in MR-DTI analysis with and without fMRI activation results. Methods: Ten right-handed normal volunteers participated in this study. DTI and fMRI datasets for each subject were obtained using a 1.5T MRI system. For neural fiber tracking, ROIs were drawn using two methods: The drawing points were located in the fMRI activation areas or areas randomly selected by users. In this study, the neural fiber tract targeted the corticospinal tract (CST) Quantitative analyses were performed and compared. The pixel numbers passing through the fiber tract in the individual brain volume were counted. The ratios between the ROI pixel numbers and the extracted fiber pixel numbers, and the ratios between the fiber pixel numbers and the whole-brain pixel numbers were also calculated. Results: According to our results, extracted CST fiber tract in which the ROI was drawn with fMRI activation areas showed higher distribution than drawing the ROI by users' hands. In addition, the quantitatively measured values represented higher pixel distribution: The counted average pixel numbers were 4553.8 and 1943.3. The average ratios of the ROI areas were 33.87 and 22.52. The average percentages of the individual whole-brain volume numbers were 2.06 and 0.87. Conclusion: Results of this study appear to indicate that use of this method can allow for more objectives and significant for study of the recovery of neural fiber mechanisms and brain rehabilitation.

Because facial asymmetry is caused by various causes, the cause analysis is important and quantitative index is needed to the evaluation. In this study, we applied the Nottingham Grading System that was used as a quantitative index to evaluate the facial paralysis by tracking the markers through the image processing and calculating the distance between the markers with images obtained by using the webcam, to evaluate facial asymmetry. The existing Nottingham Grading System has a problem of causing a measurement error in the specific case because the left and right are compared by summing the distance change between the feature points of the face part according to the change of the facial expression. We compared the case of the facial asymmetry and case of normal subject by using the existing Nottingham Grading System and the improved Nottingham grading system. In the existing Nottingham Grading System, case of facial asymmetry and case of facial symmetry were 99.0% and 95.0% respectively in the normal range, but the improved Nottingham Grading System showed facial asymmetry case was 74.0% and facial symmetrical case was 93.2%. The results of experiment show that the improved Nottingham Grading System allows detailed evaluation of each site and improved the problem of the Nottingham Grading System for specific cases.

A quantitative evaluation of postural balance training using a virtual reality bicycle system was performed. In the experiment, the effectiveness of virtual reality bicycle system on postural balance training was analyzed with four male subjects in their twenties. The parameters measured during cycling were cycling time, average velocity, number of times subject deviated from path, and weight shift. Those parameters were evaluated for the quantification of the extent of control. We also measured the parameters on postural control capability after 5th trial and 10th trial in a balance testing system with a force plate to find out the effectiveness of the training. In the balance test with force plate, it was found out that the weight shift was almost zero and the deviation from the target trace reduced significantly after the training with the virtual cycle. The result showed that the virtual bicycle system was an effective system as a rehabilitation training device.

Purpose : The purpose of this study was to investigate the quantitative evaluation of the corticospinal tract (CST) at the multiple levels by using functional MRI (fMRI) co-registered to diffusion tensor tractography (DTT). Materials and Methods : Ten normal subjects without any history of neurological disorder participated in this study. fMRI was performed at 1.5 T MR scanner using hand grasp-release movement paradigm. DTT was performed by using DtiStudio on the basis of fiber assignment continuous tracking algorithm (FACT). The seed region of interest (ROI) was drawn in the area of maximum fMRI activation during the motor task of hand grasp-release movement on a 2-D fractional anisotropy (FA) color map, and the target ROI was drawn in the cortiocospinal portion of anterior lower pons. We have drawn five ROIs for the measurement of FA and apparent diffusion coefficient (ADC) along the corona radiata (CR) down to the medulla. Results : The contralateral primary sensorimotor cortex (SM1) was mainly found to be activated in all subjects. DTT showed that tracts originated from SM1 and ran to the medulla along the known pathway of the CST. In all subjects, FA values of the CST were higher at the level of the midbrain and posterior limb of internal capsule (PLIC) than the level of others. Conclusion : Our study showed that co-registered fMRI and DTT has elucidated the state of CST on 3-D and analyzed the quantitative values of FA and ADC at the multiple levels. We conclude that co-registered fMRI and DTT may be applied as a useful tool for clarifying and investigating the state of CST in the patients with brain injury.

Objectives: There have been several studies evaluated effect of electroacupuncture (EA) on spasticity but most studies could not assess spasticity quantitatively because they used clinical rating scales for assessment spasticity. The objective of this study is to evaluate effect of EA on poststroke spasticity quantitatively using tendon reflex (T-reflex). Methods: 29 stroke patients with upper extremity spasticity were randomized to EA group and control group. The EA group received combined EA and rehabilitation therapy 5 times a week for 3 weeks. Acupuncture treatment was given at Jian Yu (LI 15), Qu Chi (LI 11), Shao Hai (HT 3), Wai Guan (TE 5), He Gu (LI 4), Lie Que (LU 7), Hou Xi (SI 3) of the affected side, 30 minutes of electrical stimulation with a frequency of 40/13 Hz was applied at Qu Chi (LI 11), He Gu (LI 4). The control group received only rehabilitation therapy. The efficacy of treatment was assessed using T-reflex latency and amplitude, modified Ashworth scale (MAS) of biceps brachii, brachioradialis and triceps brachii. Fugl-Meyer motor function assessment (FMA) and functional independence measure (FIM) were also measured to assess motor function and functional independence. All outcomes were measured before treatment, immediately after 3 weeks of treatment and 1 week after 3 weeks of treatment. Results: No statistically significant differences were found in outcomes including T-reflex between the study groups except for FIM values immediately after 3 weeks of treatment (p=0.037). Conclusions: These results suggest that 3 weeks of EA does not reduce poststroke upper extremity spasticity electrophysiologically and clinically. However, small sample sizes and contradictory tendency between results from T-reflex and those from MAS require cautious judgement on interpretation of the results. A larger, well-designed clinical trials for quantitative evaluation of effect of EA on poststroke spasticity will be needed.
