  • Objectives The purpose of this study was to evaluate the reliability and the validity of Mibyeong Questionnaire (MQ). The subjects enrolled in this study was 165 from July 2015 to Jan. 2016. The surveys were conducted twice with 3 month terms. Methods The Cronbach's ${\alpha}$ analysis for internal reliability, Pearson Correlation Coefficient analysis for test-retest reliability, Factor analysis with varimax rotation for construct validity, Kappa analysis for diagnostic reliability were used. The significant p-value was less than 0.05. Results and Conclusions The result showed that the Cronbach's ${\alpha}$ of MQ was .857-.937 and total was .913. The reliabilities between test and retest for the MQ were .666-.832 (0.416-0.673, in case of including recovery question) in intraclass correlation coefficient (ICC). The Kappa of recovery question in each item was ranged 0.23(80.6% in agreement rate) to .46(87.9% in agreement rate). In test-retest the Kappa value of Mibyeong diagnosis referred by median value was .418(71% in agreement rate). This study revealed that MQ is a reliable and valid questionnaire.

  • Objectives: This study is aimed at assessing the reliability of a standard instrument of diagnosis and assessment for Spleen Qi deficiency pattern questionnaire (SQDQ) and examining the validity of the SQDQ by comparing the pattern identification scores of different groups. Methods: We conducted a survey of 72 participants (60 patients with chronic dyspepsia and 12 healthy subjects) using self-reported questionnaire. Participants were given written consent and this study was performed under the permission of institutional review board of Kyung-Hee university Korean medicine hospital. Results: The reliability and the validity of the questionnaire were inspected. Internal consistency of the SQDQ was excellent. Construct validity analyzed by exploratory factor analysis produced 4 factors, which were selected from eigenvalues that are greater than 1.0. The factor 1, 2, 3 and 4 showed 'fatigue', 'meal', 'diagnosis' and 'figure' respectively. For most of SQDQs' items, there were significant differences observed between the Spleen Qi and the non-Spleen Qi groups. However, the 'emaciation', 'tongue diagnosis' and 'pulse diagnosis' showed no significant differences. Conclusions: The SQDQ restructured in this study may provide a fundamental questionnaire and a further study is required for a more advanced, standardized and statistically proven questionnaire.

  • Purpose: This study assessed the validity of a questionnaire (SEID-Q27) for diagnosis of chronic fatigue syndrome (CFS), designed based on the systematic exertion intolerance disorder (SEID) criteria. Methods: Two groups of participants were recruited: 1. a non-CFS control group: adult university personnel with a Chalder fatigue scale (CFQ) score ≥15, and 2. a CFS patient group: patients from an online CFS community diagnosed with CFS (diagnostic code of G93.3) with the symptoms present. The survey ran from September to October, 2020. The validity of the questionnaire was investigated by factor analysis and receiver operator characteristic (ROC) analysis. Results: Among the 35 adults surveyed, 30 (86%) participants had CFQ scores ≥15 (15 males and 15 females) and 5 (14%) had a CFS diagnosis (2 males and 3 females). The total mean score was significantly different between the two groups (CFS: 6.8±2.2 vs. control: 4.4±2.4, p<0.05). The area under the curve (AUC) was 0.827. With a cut-off point 62, the sensitivity was 60%, specificity 97%, and the discriminant ability of the survey was 79%. Conclusions: The SEID -Q27 appears to be a useful instrument for the diagnosis of CFS using SEID criteria. However, further large-scale studies are needed with greater numbers of participants.

  • 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.

  • In this paper, ECG based cardiac disease diagnosis models are developed. Conventionally, ECG monitoring equipments can only measure and store ECG signals and they always require medical doctor's diagnosis actions which are not desirable for continuous ambulatory monitoring and diagnosis healthcare systems. In this paper, two kinds of neural based self cardiac disease diagnosis engines are developed and tested for four kinds of diseases, sinus bradycardia, sinus tachycardia, left bundle branch block and right bundle branch block. For diagnosis engines, error backpropagation neural network (BP) and probabilistic neural network (PNN) were applied. Five signal features including heart rate, QRS interval, PR interval, QT interval, and T wave types were selected for diagnosis characteristics. To show the validity of proposed diagnosis engine, MIT-BIH database were used to test. Test results showed that BP based diagnosis engine has 71% of diagnosis accuracy which is superior to accuracy of PNN based diagnosis engine. However, PNN based diagnosis engine showed superior diagnosis accuracy for complex-disease diagnoses than BP based diagnosis engine.

  • Nursing Diagnosis has evolved in the guest to define nursing and its functions. But for the application to clinical practice an unified system of terminology that helps nurses to assess selected data and identify potential or actual client problems is required. Consistent terminology that captures the real meanings of the nursing diagnosis makes oral and written communication more accurate and efficient. Therefore,' this study was performed to deliver a Korean-translated version of the nursing diagnoses through the process of content validity tests and translations. Data collection for the first content validity test was done from June 27, 1996 to August 1. 1996. Among 20 questionnaires only 16 were used for analysis. With the results of content validity, the list of 109 nursing diagnoses were reviewed by two linguists, one specialized in Korean and the other in English. To clear confusion on a diagnostic label "Incontinence" a urology specialist was invited for consultation. From this analysis and discussions a total of 98 nursing diagnoses was delivered and quesitons containing 98. 98 diagnoses were mailed to 741 subjects to test content validity from August 13, 1996 to October 7, 1996. Among 741 questionnaires, 343 were used for analysis. Total mean score of the diagnoses was 4.30 on the 5 point likert scale. The diagnoses that acquired less than 3.50 were "High risk for altered body temperature"(3.34), "Ineffective thermoregulation" (3.34), "Perceived cosntipation"(3.24). "Stress incontinence"(3.42), "Ineffective airway clearance"(3. 48), "Altered sexuality patterns"(3.35).
