Background: The aim of this study is to determine the correlation between clinical assessment scales, self-assessment scales, and surface electromyography (SEMG) for facial nerve palsy. Methods: This study assessed 32 cases of facial nerve palsy on the first visit, 11 cases on the second visit, and 9 cases on the third visit to the Korean medicine hospital, university. This study was conducted from October 22, 2022, to December 22, 2022. The patients were evaluated using SEMG, clinical assessment scales, and self-assessment scales 3 times. The House-Brackmann grading systems (HBGS), Yanagihara unweighted grading system (Y-score), facial disability index, numerous rating scale, and accompanying symptoms of facial nerve palsy were used for assessment. Moreover, statistical correlation was analyzed using Pearson correlation. Results: On Visit 1, Significant correlations were observed between the results of SEMG and other clinical assessment scales as well as between SEMG-F (frontalis) and different parts of the Y-score. On Visit 2, significant correlations were observed between the results of SEMG and HBGS as well as between SEMG-F and the detailed parts of the Y-score. On Visit 3, significant correlations were observed only between SEMG-F and the detailed parts of the Y-score. A significant correlation was also observed between the changes in the clinical assessment scales on Visits 1 and 3 and between the changes in SEMG-F and those in the patient self-assessment scales. Conclusion: These findings suggest that SEMG can be used to evaluate facial nerve palsy in conjunction with the use of other clinical assessment scales.

연구목적: 대한치과보철학회지에 사용된 통계적 방법의 통계적 오류현황을 파악하여 통계적 방법의 잘못된 활용으로 인한 치의학 연구논문에서의 문제를 검토하고, 또한 통계적 오류의 유형과 빈도를 파악하여 동일문제의 재발 방지 및 효율적 대처의 기회로 삼고자 함이다. 연구 재료 및 방법: 2000년부터 2006년까지의 대한치과보철학회지에 게재된 총 399편의 논문 중 통계적 방법이 사용된 292편의 논문을 조사했고, 이를 위해 1997년 국제의학학술지 편집위원회의 "생의학 학술지에 투고하는 원고의 통일양식의 통계학적 방법론에 관한 서술지침" 15개항을 기초로 하여 1) 통계 프로그램의 불명시, 2) 통계 방법의 부적절한 기술, 3) 통계용어의 오용 등으로 크게 3가지 범주로 구성된 점검표를 사용하여 통계적 방법의 종류 및 통계적 오류부분을 확인하고 이를 한글판과 영문판으로 비교해 보았다. 그 결과는 다음과 같다. 결과 및 결론: 1. 통계 프로그램 명시 오류는 한글판에선 54%가, 영문판에선 59%가 있었으나 통계적으로 유의한 차이를 보이진 않았다 (P = .66). 2. 통계 방법의 부적절한 기술에 관한 오류는 한글판에선 49%가, 영문판에선 33%가 있었으나 통계적으로 유의한 차이를 보이진 않았다 (P = .09). 3. 통계용어의 오용오류는 한글판에선 54%가, 영문판에선 24%가 있었으며 통계적으로도 유의한 차이가 있었다 (P = .01). 상기 결과로 볼 때 통계용어의 오용 오류 이외엔 통계적 유의성을 보이진 않아서 한글판과 영문판의 통계적 오류의 비율은 유사하게 나타난 걸로 추정되며, 전체적으로 대한치과보철학회지의 통계적 타당성은 다소 부족하게 나타났다. 따라서 향후 치의학 연구자는 통계적 방법을 기술하고 적용할 때 통계적 오류를 피하기 위해 주의를 기울여야 할 것이며, 아울러 치의학 논문에서의 통계학적 방법론에 대한 인식의 제고가 필요하다고 보인다.

Sound quality engineering in automobile noise applications has become more and more important under the current quiet driving condition because various noise components masked under high noise level can be audible in quieter driving situation. Many researches have been carried out for subjective and objective assessments on automobile sounds and noises. In particular, the interior sound quality has been one of research fields that can give high-quality feature to automobile products. Although many works related to the interior sound quality have been progressed or completed in foreign countries, limited research results are presented in the country. In the study, subjective assessments are first performed with 20 subjects to select perceptual adjectives suitable to the assessment of car interior noises during acceleration. The selected perceptual adjectives are employed as the assessment scales to evaluate the acceleration noises in questionnaire procedures using 35 subjects, for which several noises are created through digital filtering of the acceleration noises measured. Mean values and standard deviations for subjective assessment scores obtained by the questionnaire procedures are calculated and their reliability are also verified. Finally, various statistical analyses such as the correlation analysis and the factor analysis are carried out to reveal the interrelationship between the assessment scales and the spectrum components of the acceleration noises.

Purpose: This study was to examine the reliability and validity of the Korean version of the Cornell Assessment of Pediatric Delirium (CAPD). Methods: For testing the reliability of the Korean version of the CAPD, this study calculated the internal consistency (Cronbach's α) and the Interrater Correlation Coefficient (ICC) by comparing the independent assessment results of three nurses in Pediatric Intensive Care Unit (PICU). For testing the validity of the Korean version of the CAPD, the assessment result of the Korean version of the CAPD compared with that of the Diagnostic and Statistical Manual of Mental Disorders V (DSM-V). Receiver Operating Characteristics (ROC) analysis was used for measuring sensitivity and specificity. Results: Overall interrater reliability of the Korean version of the CAPD, ICC was .98 (95% CI .96~.99). Cronbach's α was .91 for eight items. The concordance between the Korean version of the CAPD and psychiatrist's diagnosis was 90.0%. When the Korean version of the CAPD has the cut point of 9, sensitivity was 93.8%, and specificity was 75.0%. The area under the curve indicated by the ROC analysis was .88. Conclusion: The Korean version of the CAPD showed good reliability and validity. This tool will be useful for pediatric delirium screening and management in Korean PICU.

Information Technology (IT) and the internet have been major drivers the changes in all aspects of the business processes and activities. They have brought major changes to the financial statements audit environment as well, which in turn has required modifications in audit procedures. There exist, however, certain difficulties with current audit procedures especially for the assessment of the level of control risk. This assessment is primarily based on the auditors' professional judgment and experiences, not based on the objective hies or criteria. To overcome these difficulties, this paper proposes a prototype decision support model named CRAS-CBR using case based reasoning (CBR) to support auditors in making their professional judgment on the assessment of the level of control risk of the general accounting system in the manufacturing industry. To validate the performance, we compare our proposed model with benchmark performances in terms of classification accuracy for the level of control risk. Our experimental results showed CRAS-CBR outperforms a statistical model (MDA) and staff auditor performance in average hit ratio.
