Diplophonia is generally defined as the perception of more than one fundamental frequency component in a voice. Its perceptual aspect has traditionally been used to evaluate diplophonia because the perceptions can be easily evaluated, but there are limitations in the validity of the reliability of the intra- and inter-raters, examination situation, and variation of voice sample. Therefore, the purpose of this study is to confirm the reliability and accuracy of auditory perceptual evaluation by comparing non-invasive indirect assessment methods (sound waveform and EGG analysis), and to identify their usefulness with diplophonia. A total of 28 diplophonic voices and 39 non-periodic voices were assessed. Three raters assessed the diplophonia by performing an auditory perception evaluation and identifying the quasi-periodic perturbations of the acoustic waveform and EGG. Among the three discrimination methods, intra- and inter-rater reliability, sensitivity, specificity, accuracy, positive likelihood ratio, and negative likelihood ratio were examined, and the McNemar test was performed to compare the discriminant agreement. The accuracy of the auditory perceptual evaluation (86.57%) was not significantly different from that of sound waveform acoustic (88.06%), but it was significantly different from that of EGG (83.33%). The reading time (6.02 s) for the auditory perceptual evaluation was significantly different from that for sound waveform analysis (30.15 s) and EGG analysis (16.41 s). In the discrimination of diplophonia, auditory perceptual evaluation has sufficient reliability and accuracy as compared to sound waveform and EGG. Since immediate feedback is possible, auditory perceptual evaluation is more convenient. Therefore, it can continue to be used as a tool to discriminate diplophonia in clinical practice.

Purpose : The examine the reliability and validity of the modified Emory Functional Ambulation Profile(mEFAP) for assessing gait function in chronic stroke patients. Methods : A total of 45 stroke patients, who had a stroke more than 6 months, participated in the study. Reliability was determined by Intra-class Correlation Coefficient($ICC_{3,1}$), including Bland and Altman method (Standard Error of Measurement: SEM, Small Real Differences: SRD). Validity was examined by correlating results to the gait ability(mEFAP, Modified Motor Assessment Scale-Gait(MMAS-G), Scandinavian Stroke Scale-Gait(SSS-G), Functional Ambulation Category(FAC), 10m Waking Test(10m WT)), and Fugl Meyer-Lower/Extremity(FM-L/E), Berg Balance Scale(BBS). Results : Inter-rater reliability for the total mEFAP was High($ICC_{2,1}$=.998), and absolute reliability were excellent (SEM: 1.75, SRD: 4.85). Subjects without assistance factor performed better on all tests than did subjects who had stroke. There were significant correlations between the mEFAP and MMAS-G, SSS-G, FAC(r=-.66~-.79), 10 m WT(r=-.86), and FM-L/E, BBS(r=-.72~-.78), indicating good validity. Increased times on the mEFAP correlated with poor performance on the gait ability, motor function of lower extremity, BBS and slow gait speeds on the 10 m WT in stroke patients. Conclusion : The mEFAP can be administered easily and comprehensively. It is a reliable gait assessment tool for patients with stroke and correlated with known of function, the mEFAP may be a clinically useful measure of ambulation.

The purpose of the present study was to conduct a preliminary study for developing a Korean version of the Fine Motor Scale of the Bayley Scales of Infant and Toddler Development, $3^{rd}$ Edition(Bayley-III). The subjects for this study included 313 Korean infants and toddlers aged from 16 days to 42 months and 15 days. The results of this study were as follows. Firstly, the analysis of the degree of item difficulty indicated that the arrangement of the items corresponded with child development by age. Secondly, the analysis of the inter-item consistency, the test-retest reliability and the inter-rater reliability revealed a high degree of reliability of the scale. Thirdly, the Fine Motor Scale of K-Bayley-III score showed a significant high correlation with the Motor composite score but a significant moderate correlation with the Language composite score, providing evidence of its convergent and discriminant validity. This study demonstrated that the preliminary version of the K-Bayley-III Fine Motor Scales can be applied to assess the development of fine motor skills of Korean infants and toddlers.

Objective: The study examined the validity and reliability of tele-assessment of cervical range of motion (ROM) through video conferencing. Design: A cross-sectional study Methods: The study included 22 healthy adults as subjects and 10 physical therapists as evaluators. The subjects underwent both face-to-face and tele-assessment of cervical ROM. The CROM (Cervical Range of Motion) device was used for reference measurements in the face-to-face assessment. The evaluators assessed the subjects' ROM through visual inspection (VI) and using a Universal Goniometer (UG) in the tele-assessment. Results: The results showed a significant correlation between the face-to-face and tele-assessment measurements for all ROM contents. The correlation coefficients ranged from r=0.54 to 0.71 (p<0.05), indicating concurrent validity. In terms of inter-rater reliability, the ICC values for both VI and UG assessments in the tele-assessment were high, with ICCs of 0.93 and 0.92, respectively. Additionally, the study investigated the usability of the tele-assessment method and environment. The satisfaction of the participants and evaluators was assessed using the Telehealth Usability Questionnaire (TUQ), which evaluates perceptions, usability, and satisfaction with telehealth services. Conclusions: In conclusion, tele-assessment of cervical range of motion using video conferencing was valid and reliable. Also, investigated participant and evaluator satisfaction and opinions, providing insights into the clinical value of tele-assessment. It is important to note that the study was conducted only healthy adults, and further research may be needed to validate the tele-assessment method in populations with cervical dysfunction or neck pain. These findings support the potential effectiveness of telerehabilitation services in assessing and managing musculoskeletal disorders.

This study was to investigate for comparison between single rating and average ratings from multiple presentations of the same stimulus for measuring the voice quality of dysphonia using 7-point equal-appearing interval (EAI) rating scale. Overall severity of voice quality for 46 /a/ vowel stimuli (23 stimuli from dysphonia, 23 stimuli from control) was rated by 3 experienced speech-language pathologists (averaged 19 years; range = 7 to 40 years). For average ratings, each stimulus was rated five times in random order and averaged from two to five times. Although higher inter-rater reliability was found in average ratings than in single rating, there were no significant differences in rating scores between single and multiple average ratings judged by experienced listeners, suggesting that auditory perceptual ratings judged by well-trained listeners have relatively good agreement with the same stimulus across the judgment. Larger variations in perceptual ratings were observed for moderate voices than for mild or severe voices, even in the average ratings.

News in the form of web data generates increasingly large amounts of information as unstructured text. The capability of understanding the meaning of news is limited to humans; thus, it causes information overload. This hinders the effective use of embedded knowledge in such texts. Therefore, Automatic Knowledge Extraction (AKE) has now become an integral part of Semantic web and Natural Language Processing (NLP). Although recent literature shows that AKE has progressed, the results are still behind the expectations. This study proposes a method to auto-extract surface knowledge from English news into a machine-interpretable semantic format (triple). The proposed technique was designed using the grammatical structure of the sentence, and 11 original rules were discovered. The initial experiment extracted triples from the Sri Lankan news corpus, of which 83.5% were meaningful. The experiment was extended to the British Broadcasting Corporation (BBC) news dataset to prove its generic nature. This demonstrated a higher meaningful triple extraction rate of 92.6%. These results were validated using the inter-rater agreement method, which guaranteed the high reliability.
