The perspective of ‘a good doctor’ on university students
YoungJoon Ahn 조선대학교 의학연구원 2021 Medical Bilogical Science and Engineering Vol.4 No.1
People consider a doctor’s attributes and competencies in treating patients to be important when defining what a “good” doctor is. To determine the necessary attributes to develop “good” doctors, we analyzed questionnaires that were answered by university students. There were 154 male and 318 female university students that answered the questionnaires. The religions of the students were 249 (52.8%) in atheist, 122 (25.8%) in christian, 49 (10.4%) in catholic, 45 (9.5%) in buddhist and 7 (1.5%) in others. They thoughts that 1st factor as an excellent doctor was skilful and knowledgeable in 53.2% and 2nd was to give full explanation in 32.6% and 3rd was kind in 13.8%. They thoughts as a reliable doctor that 1st was to work at university hospital and 2nd at general hospital and 3rd at middle-sized hospital and last at private clinics. They needed to educate a professional skill and knowledge and active communication with patients for nurturing a good doctor. They thoughts that the reliability for doctor was 3.4 and for medical service 3.3 by Likert 5 scales. University students thought that a good doctor was skilful and knowledgeable and to explain in detail with patients and their caregiver fluently.
Ultrasound assisted batch-processing of EVA-organoclay nanocomposites
이재욱,Youngjoon Ahn,Hyungsik Kim 한국화학공학회 2010 Korean Journal of Chemical Engineering Vol.27 No.2
The aim of this study was to investigate the effect of ultrasound on the properties of a poly[ethylene-co-(vinyl acetate)] (EVA)-organoclay nanocomposite. By using a torque rheometer, in-situ rheological behaviors of various EVA resins with varying VA content were examined. It was found that the effect of ultrasound was most significant for EVA 31 (31 wt% VA). EVA31/organoclay nanocomposites were prepared in batch mixer with and without irradiation of ultrasound. The characterization of the nanocomposite was performed using XRD, TEM, rheometry, and universal testing machine. XRD and TEM results revealed that the produced EVA31/organoclay nanocomposite with ultrasonic irradiation possessed intercalated structure. Rheometry result indicated that EVA31/organoclay nanocomposite processed with ultrasound had a highly disordered or delaminated structure. A considerable increase in stiffness and Young’s modulus for the sonicated nanocomposite compared to those for unsonicated one was obtained. This study demonstrated the possibility of producing EVA-organoclay nanocomposites with enhanced dispersion of nanoclays using ultrasound assisted processing.
