The purpose of the present study was to examine dental hygienists' perception of the current national practical examination. This research was performed using 199 self-reported surveys answered by professors of dental hygiene studies and clinical dental hygienist. Frequency analysis, chi-square tests, and analysis of variance were performed by using IBM SPSS Statistics ver. 20.0. The results revealed that many of the respondents consider the current national practical examination to be neutral. They did not think that the current national practical examination questions are useful for assessing occupation-centric integrated clinical practice ability and counseling techniques for patient intervention. The professors of dental hygiene studies believed that among the research tasks required as mentioned in the national practical examination questions, dental polishing and tooth brushing education are of paramount importance, whereas clinical dental hygienists believed that ultrasonic scaling is the most important (p<0.05). Most of the professors of dental hygiene studies reported that they conducted skills education for dental polishing and tooth brushing education, while most of the clinical dental hygienists reported that tasks actually performed in the clinic included impression taking, model fabrication, ultrasonic scaling, and explaining treatment precautions (p<0.05). Therefore, these tasks can be effectively carried out with the improvement of the national dental hygienist practical examination.

BACKGROUND/AIMS: The optimal training mode for linear array endoscopic ultrasonography (EUS) has not been established. Prior radial-scanning EUS training seems to improve subsequent linear array EUS learning. The objective of this randomized controlled trial was to evaluate its value in linear array EUS training. METHODS: In total, 18 freshman trainees conducted hands-on EUS operations on a live pig model. The training contents consisted of visualization and tracking of the pancreas and splanchnic vasculature and performing fine-needle aspiration of the body or tail of the pancreas and celiac plexus neurolysis through the stomach. The trainees were randomized into two groups: group A received linear array EUS training after receiving radial-scanning EUS training, whereas group B conducted linear array EUS training alone. Two teachers assessed the competence of each trainee using a scoring system and relevant parameters before and after the training process. RESULTS: Groups A and B showed significant improvement between the pretests and posttests in terms of diagnostic and interventional procedures. There was no intergroup difference in terms of improvement. CONCLUSIONS: Prior radial-scanning EUS training did not contribute to subsequent linear array EUS study performance in the pig stomach model; thus, this training mode may need to be changed.

Sonography is a subjective diagnostic method which is highly dependent on the experience of the operator and the equipment quality which requires real-time adjustments. Breast screening examination currently consists of clinical examination and mammography. Breast sonography, either supplementary to mammography or independently, is indicated for the dense breast, especially in younger women. Breast sonography is especially applicable for Korean women because of the denser breast parenchyma and the approximately 10-year younger incidence rate of breast cancer of Korean women compared to western women. To avoid unnecessary breast biopsy because of the high rate of false positive lesions in breast parenchyma, which is different from other body organs such as the liver or the kidney, a quality assurance program for breast sonography is essential. The quality assurance of breast ultrasound involves quality assurance of the equipment, imaging display and acquisition of clinical images, personnel qualifications and other aspects such as unification of lexicon, guideline of diagnostic examination and reporting system; US BI-RAD reporting system, assessment items and organization, education program, medical audit, certification issues, and medicolegal issues. A breast sonographic quality assurance system should be established before a scheme to initiate governmental medical insurance for breast sonography.
