The purpose of this study was to investigate the test-retest reliability of speech recognition thresholds (SRTs) measured by Korean standard bisyllabic word list for adults (KS-BWL-A). Thirteen normal-hearing adults (14 ears) and 67 hearing-impaired persons (93 ears) with sensorineural hearing loss (SNHL) participated in this study. Subjects with SNHL were categorized into four groups: 1) mild hearing loss, 2) moderate hearing loss, 3) moderately severe hearing loss, and 4) severe-to-profound hearing loss. Pure tone audiometry and the SRT test with KS-BWL-A were administered in all participants. The SRTs were mathematically calculated based on the national and international standards (ISO 8253-3, 2012, KS I ISO 8253-3, 2009). The retest of the SRTs was performed within two weeks with the same procedure as the initial test. Results showed that the first SRTs were highly correlated with the second SRTs for normal-hearing and hearing-impaired groups. There was no significant difference between the first and second SRTs for normal-hearing group. For hearing impaired groups, the second SRTs were slightly decreased than the initial SRTs in all four groups. The 95% confidence intervals for each group were between ± .82 ~ ±1.44 dB and the 95% prediction intervals of individual scores for each group were between ±3.10 ~ ±4.34 dB. Results recommend that SRT test using the KS-BWL-A be a reliable method in every category of SNHL as well as normal-hearing based on high correlation, narrow CI and PI. It is also suggested that a difference greater than 5 dB between the first and second SRTs be interpreted as significant in clinical situations.

The article analyzes the historic inevitability of which chinese Government chose the production-typed VAT legal system in 1994 on the basis of the research and comparison to national VAT laws. Now, VAT has become the largest tax in chinese tax system, and VAT law has been the most important component in Chinese tax system. However, along with the rapid development of economy, VAT law has increasingly exposed a good many of maladies which impede economic development. Therefore, China keep the transition of VAT as the central task to undertake reforms. But the post-transformation VAT is a non-completed consumption AVT, and it still need to be further improved.

Background : Cervicovaginal cytology is a screening test of uterine cervical cancer. The sensitivity of cervicovaginal cytology is less than 50%, but studies of cytologic/histologic correlation are limited. We analyzed the diagnostic accuracy of cervicovaginal cytology in the detection of the squamous epithelial lesions of the uterine cervix and investigate the cause of diagnostic discordance. Materials and Methods : We collected a total of 481 sets of cervicovaginal cytology and biopsies over 5 years. The cytologic diagnoses were categorized based on The Bethesda System and the histologic diagnoses were classified as negative, flat condyloma, cervical intraepithelial neoplasia (CIN) I, CIN II, CIN III, or squamous cell carcinoma. Cytohistologic discrepancies were reviewed. Results: The concordance rate between the cytological and the histological diagnosis was 79.0%. The sensitivity and specificity of cervicovaginal cytology were 80.6% and 92.6%, respectively. Its positive predictive value and negative predictive value were 93.7% and 77.7%, respectively. The false negative rate was 19.4%. Among 54 false negative cytology cases, they were confirmed by histology as 50 flat condylomas, 2 CIN I, 1 CIN III, and 1 squamous cell carcinoma. The causes of false negative cytology were sampling errors in 75.6% and interpretation errors in 24.4%. The false positive rate was 7.4%. Among 15 false positive cytology cases, they were confirmed by histology as 12 atypical squamous cells of undetermined significance (ASCUS) and 3 low grade squamous intraepithelial lesions (LSIL). The cause of error was interpretation error in all cases. The overall diagnostic accuracy of cervicovaginal cytology was 85.7%. Conclusions : Cervicovaginal cytology shows high overall diagnostic accuracy and is a useful primary screen of uterine cervical cancer.
