  • The Connected Speech Test (CST) was developed to test hearing aid performance using realistic stimuli (Connected speech) presented in a background of noise with a visible speaker. The CST has not been investigated as a measure of speech reading ability using the visual portion of the CST only. Thirty subjects were administered the 48 test lists of the CST using visual presentation mode only. Statistically significant differences were found between the 48 test lists and between the 12 passages of the CST (48 passages divided into 12 groups of 4 lists which were averaged.). No significant differences were found between male and female subjects; however, in all but one case, females scored better than males. No significant differences were found between students in communication disorders and students in other departments. Intra- and inter-subject variability across test lists and passages was high. Suggestions for further research include changing the scoring of the CST to be more contextually based and changing the speaker for the CST.

  • Small boat operator's certificate of competency took up 39.0% of total license holders and required for at least 19,000 boats in 2013, was proposed the improvement items by reviewing the acts and criteria related to the current test and analyzed the questions of set at examinations. About 31% of questions of the current written test are unsuitable for the target boat and operational knowledge of the operator. It is appropriate that the subject categorization criteria and contents of the subjects will be improved to include practical details related to safe ship operation, and the number of questions increased according to each subject category in amended examination after January 1st, 2017. The interview test should be improved so that the questions can be forwarded in a clear manner through formulation of practical problems, photos, etc. considering the real situations such as high age/low education status of testee and it is necessary to lengthen the interview time per testee. The test and interview personnel should consist of a human resource pool with experience in small boat operator training and workers of related areas familiar with field terminology. Furthermore, the test should be divided into small boats of 2 to 5 tons and those exceeding 5 tons according to the tonnage of small boats.

  • Background: Understanding the history of human papilloma virus (HPV) infection is important for interpretation of a positive HPV DNA screening test, future work-up and treatment. We investigated the transition of HPV DNA test results in Korean women, and analyzed the association of cytology result with transition type. Materials and Methods: We retrospectively reviewed annual HPV DNA test results for 5,274 subjects between January 2005 and December 2012. Each subject had a minimum of five annual tests over the eight-year period. Based on the pattern of results, the transition type for each subject was assigned to one of the following: negative, persistent, latent, transient, and unclassifiable. Associations of cytology results with the HPV DNA transition types, number of positive results, and the durations of positive results were also analyzed. Results: The proportion of abnormal cytology findings decreased in the following order of transition patterns: persistent, latent, transient, and negative. Among transient patterns, a duration of three years or more significantly correlated with cytology results of non-high grade squamous intraepithelial lesion (HSIL; p<0.001). In the persistent group, duration of five years or more correlated with both non-HSIL and HSIL (p<0.001). Latent group showed no correlation with duration. Irrespective of patterns, having five or more positive results was significantly associated with HSIL (p<0.001). Conclusions: Our findings may contribute to better understanding of HPV infection, interpretation of HPV DNA screening results, and prediction of prognosis according to transition type.
