The purpose of this study was to evaluate the reliability and validity of the Force-Sensing Resistor (FSR) for measurement of static hindlimb weight distribution in beagle dogs and to compare these results to a Digital Weighing Scale (DWS). Nine healthy beagle dogs were recruited for this study. Static weight distribution was evaluated four times at intervals of 5 days with each device and two observers to calculate the intra- and interobserver reliability. The intraclass correlation coefficient (ICC) values of the FSR for intraobserver reliability were moderate to good (0.74). The results for the DWS showed poor to moderate (0.56) ICC values for intraobserver reliability. The ICC values for interobserver reliability were 0.53 and 0.61 for FSR and DWS, respectively, indicating poor to moderate agreement. Our findings suggest that the Force-Sensing Resistor can be used to measure static weight distribution in veterinary medicine. However, caution should be taken when comparing measured values of static weight distribution obtained utilizing both the FSR and DWS due to their low positive correlation (R = 0.41, p < 0.01).

Purpose: The purpose of this study was to examine the effects of team-based learning (TBL) program on problem solving ability, critical thinking disposition and self-directed learning in junior nursing students caring for patients with respiratory diseases. Methods: One-group pretest-posttest design was used. TBL program was carried out for 2 hours a week for 6 weeks. Data were collected by questionnaires from 167 nursing students from March 6 to June 5, 2013. Data were analyzed by paired t-test and Pearson correlation coefficient. Results: At the completion of TBL program, significant improvement was found in problem solving ability (t=-6.04, p<.001), critical thinking disposition (t=5.02, p<.001) and self-directed learning (t=5.96, p<.001). There was a significant positive correlation among problem solving ability, critical thinking disposition and self-directed learning. Conclusion: In conclusion, TBL is a useful teaching and learning method on nursing students. We suggest that it is needed to measure the educational effects of TBL against other teaching methods in the future studies.

The purposes of this study were to examine the reliability and validity of Korean translation of Pediatric Evaluation of Disability Inventory (PEDI-K) in school-aged children with cerebral palsy (CP). The PEDI-K, Functional Independence Measure for Children (WeeFIM) and Gross Motor Function Classification System (GMIFCS) were completed in 104 school-aged children with CP by therapists. The internal consistency of the PEDI-K was calculated by Cronbach's alpha (${\alpha}$) for assessing reliability. Concurrent validity was evaluated by correlation with the subsets of WeeFIM. Discriminant validity was assessed by comparing GMFCS levels with tests of the PEDI-K. The results showed that internal consistency was good (Cronbach's ${\alpha}$ ranged from .97~.98). Concurrent validity was demonstrated. The correlation with WeeFIM was high in the Functional Skills (self-care, r=.74~.94; mobility, r=.59~.91; social function, r=.65~.93) and in the Caregiver Assistance (self-care, r=.75~.94; mobility, r=.63~.90; social function, r=.78~.96). Discriminant validity was demonstrated on significant decreases in domain scores with increasing GMFCS levels. Reliability and validity have been demonstrated on the PEDI-K. This study extends usage of PEDI-K in clinical activities and research.

The purpose of the present study were (1) to assess differences in tongue performances and speech intelligibility between normal and dysarthric speakers; and (2) to analyze the possible interrelationships between tongue strength, range of motion, and speech intelligibility in dysarthric patients. In order to measure maximum strength of anterior and lateral tongue strength, a force transducer has been designed. And a ruler was used for guaging range of motion. 'Word intelligibility test' was administered to each group. The results were analyzed by a quantitative statistical method(t test, Pearson product- moment correlation, and one-way ANOVA). The results were as follows; (1) dysarthric speakers showed significantly poorer performance than the normal in the tongue strength, range of motion, and speech intelligibility tasks; (2) the correlation between speech intelligibility and instrumental tongue performance was high in the dysarthric group; and (3) instrumental assessment was coincide with perceptual judgement of dysarthric tongue performance. The present investigation demonstrated that tongue weakness is causally related to articulation deficits in dysarthric. The clinical use of the force transducer would help a speech pathologist to quantify the degree of tongue weakness.

The author had selected the roots and root-canal as measurable parts and sought the area ratio by measuring the respective areas of the root. Further, heplotted out a root caual index and studied the correlation with age. The teeth used as reserch material were permanent maxillary central incisors of Korean female. Some 296 teeth of known age were selected on condition that there is no caries or filling material and that they were not malformed in showing normal signs in roentgenograms. The $3" {\times} 4"$ printing paper so as to measure easily. On the ocassion of measureing the area of measured parts with a planimeter (Koizumi, type kp-27, Japan), the cervical lines were joined up into a straight line on a photograph (Figure 1) Root canal index = Area of the root / Area of the root canal The results of the root canal index in Korean female age groups were as follows : 1. The root canal index of maxilary central incisor in women was 4.74 im 20 years of age, 5.44 in 30, 5.90 in 40, 6.32 in 50, 6.63 in 60 in the order. 2. Root canal index and age were in positive correlation ; there was a tendency that the root canal index increase as age advances. 3.

Purpose: The study examined the psychometric properties of the Korean Geriatric Depression Scale Informant-15 (KGDSI-15), an instrument measuring geriatric depression through their primary caregivers. Methods: The participants were 370 Korean older adults $\geqq$65-years-of-age registered in a visiting health center in S city. The Korean version of Geriatric Depression Scale-Short Form (GDSSF-K) was used for comparison. Internal consistency measured tool reliability and Pearson correlation coefficient measured validity. One-way ANOVA was used to determine the clinical usability of the instrument: depression levels were classified as normal, mild depression, and severe using GDSSF-K, and the depression scores of these three groups were comparatively measured by KGDSI-15. Results: The Cronbach's alpha coefficient was .831. The correlation coefficient with GDSSF-K was r=.616 (p<.001). KGDSI-15 results showed the depression level of older adults with severe depression was highest followed by those with mild depression and normal. The group differences were also statistically significant, which indicated the clinical usability of the instrument. Conclusion: KGDSI-15 is suggested to be reliable and valid to measure the geriatric depression through the primary caregivers of older adult.

The purpose of this study was to evaluate the resistant force of medial pterygoid muscles against the mandibular advancement and distraction to anterior, and inquire into the relationship between medial pterygoid muscles and cephalometric variables. Sixty six patients with class III malocclusion underwent bilateral sagittal splitting of ramus with intraoralvertico-sagittal ramus osteotomy for mandibular set-back. The spring scale was used to measure the resistance of medial pterygoid muscles after splitting of ramus. Skeletaldental cephalometric analysis was made and statistic package was used for correlation between resistance and cephalometric variables. The resistant force of the right medial pterygoid muscle was greater than the left one in Koreans with class III malocclusion, and the force had a linear regression relationship with facial depth. The results suggested that facial depth has significant correlation with the resistance of medial pterygoid muscle, which can be acquired from patient's cephalometric analysis.

This paper describes development of a high speed Doppler OFDI system for non-invasive vascular imaging. Doppler OFDI (optical frequency domain imaging) is one of the phase-resolved second generation OCT (optical coherence tomography) techniques for high resolution imaging of moving elements in biological tissues. To achieve a phase-resolved imaging, two temporally separated measurements are required. In a conventional Doppler OCT, a pair of massively oversampled successive A-lines is used to minimize de-correlation noise at the expense of significant imaging speed reduction. To minimize a de-correlation noise between targeted two measurements without suffering from significant imaging speed reduction, several methods have been developed such as an optimized scanning pattern and polarization multiplexed dual beam scanning. This research represent novel imaging technique using frequency multiplexed dual beam illumination to measure exactly same position with aimed time interval. Developed system has been verified using a tissue phantom and mouse vessel imaging.
