Impact of video feedback system on medical students' perception of their clinical performance assessment.

Background: Providing feedback on student performance in the clinical performance assessment (CPA) is meaningful in that it helps students understand their strengths and weaknesses. This study compared students' perception of their CPA scores before and after providing personalized video feedback.

Methods: Two identical online surveys of Year 1 medical students (N = 103) that had undergone CPA were conducted to evaluate students' perceptions about their CPA scores before and after video feedback.

Holistic rubric vs. analytic rubric for measuring clinical performance levels in medical students.

Background: Task-specific checklists, holistic rubrics, and analytic rubrics are often used for performance assessments. We examined what factors evaluators consider important in holistic scoring of clinical performance assessment, and compared the usefulness of applying holistic and analytic rubrics respectively, and analytic rubrics in addition to task-specific checklists based on traditional standards.

Methods: We compared the usefulness of a holistic rubric versus an analytic rubric in effectively measuring the clinical skill performances of 126 third-year medical students who participated in a clinical performance assessment conducted by Pusan National University School of Medicine.

Effects of micro- and subtle-expression reading skill training in medical students: A randomized trial.

Objective: to investigate the effectiveness of the Micro Expression Training Tool (METT) and the Subtle Expression Training Tool (SETT) to help improve the non-verbal communication skills of medical students.

Methods: In a randomized controlled trial, all participants were randomly allocated to either a training (n=41) or control group (n=41) and were pre-tested before education with METT and SETT at baseline. Then, training students took second tests after a 1-h class about interpreting micro and subtle expressions and control students took the second tests without the class.

A pilot study on the evaluation of medical student documentation: assessment of SOAP notes.

Purpose: The purpose of this study was evaluation of the current status of medical students' documentation of patient medical records.

Methods: We checked the completeness, appropriateness, and accuracy of 95 Subjective-Objective-Assessment-Plan (SOAP) notes documented by third-year medical students who participated in clinical skill tests on December 1, 2014. Students were required to complete the SOAP note within 15 minutes of an standard patient (SP)-encounter with a SP complaining rhinorrhea and warring about meningitis.

[Two-and-a-half year follow-up study of strategy factors in successful learning to predict academic achievements in medical education].

Purpose: We performed a two-and-a-half year follow-up study of strategy factors in successful learning to predict academic achievements in medical education.

Methods: Strategy factors in successful learning were identified using a content analysis of open-ended responses from 30 medical students who were ranked in the top 10 of their class. Core words were selected among their responses in each category and the frequency of the words were counted.

Experience of clinical skills assessment in the Busan-Gyeongnam Consortium.

Purpose: The purpose of this study is to judge the quality of clinical skills assessment in Busan-Gyeongnam Consortium.

Methods: Fourth grade medical school students (n=350 in 2012 and n=419 in 2013) in the Busan-Gyeongnam Consortium were included in the study. The examination was consisted of 6 clinical performance examination (CPX) and 6 objective structured clinical examination (OSCE) stations.

Group counseling for medical students with drop-out experiences.

Purpose: The purpose of this research was to describe our group counseling methods for medical students with drop-out experiences.

Methods: Group counseling was offered to 11 medical students with drop-out experiences in their previous second semester. All subjects provided written informed consent before participating and completed a 2-day group counseling program using the Gestalt approach.

The impact of bladder distension on blood pressure in middle aged women.

Background: The purpose of the present study was to investigate the relation between the extent of bladder distention and the rise of blood pressure in middle aged women.

Methods: In a cross-sectional, descriptive observational study, we obtained data from 172 middle aged women at a health promotion center of Pusan National University Hospital. We measured duration of urine-holding as the degree of the extension of bladder distention.

Analysis of questioning technique during classes in medical education.

Background: Questioning is one of the essential techniques used by lecturers to make lectures more interactive and effective. This study surveyed the perception of questioning techniques by medical school faculty members and analyzed how the questioning technique is used in actual classes.

Methods: Data on the perceptions of the questioning skills used during lectures was collected using a self-questionnaire for faculty members (N = 33) during the second semester of 2008.

Differential expression of ghrelin mRNA according to anatomical portions of human stomach.

Background/aims: The detailed ghrelin distribution on mRNA level in different anatomical portions of adult stomach and its association with plasma ghrelin levels are not yet well established. We investigated the ghrelin mRNA and peptide expression in different anatomical portions of stomach in human adults.

Methodology: Stomach tissue samples were obtained from 16 patients with gastric cancer who underwent total gastrectomy.
