This research focuses on the Fourth Industrial Revolution and Korean National Competency Standards. The aim of this is to perform a comparative study two university engineering courses present difference between effect virtual reality (VR)-based teaching traditional learning robotics. To achieve goal, authors used expert method, focus group interviews, study. There were three hypotheses four questions relationship method competency development. As case for research, chose Korea University...

As there is increased concern over the radiation exposure particularly in adolescents and young adults, computed tomography (CT) dose reduction needed diagnosis of acute appendicitis.To evaluate optimal strength sinogram affirmed iterative reconstruction (SAFIRE) to obtain best image quality on a 30-mAs applied low-dose CT (LDCT 30mAs) compare diagnostic performances LDCT 30mAs with different SAFIRE strengths that 100-mAs 100mAs) for appendicitis.A total 102 consecutive patients (47 men, 55...

This study was undertaken to determine the concentrations of volatile organic compounds (VOCs) in indoor air atopy patients' (atopic dermatitis 50, allergic asthma 36) and control houses (28 nonpatients). A goal this also investigate whether VOCs were risk factors for development atopic sensitization. Eleven alkanes, 13 aromatics, 7 chlorinated hydrocarbons, 3 terpenes, 15 aldehyds measured from 10 March June, 2006. Aldehyde are most abundant chemical group all air, followed by aromatic...

BACKGROUND: Accurate and timely diagnosis of acute surgical disease in pregnant patient is challenging.Although magnetic resonance imaging (MRI) the most accurate modality to diagnose appendicitis patients, it often used as a last resort because high cost long scan time.We performed this study analyze differential diagnoses appendix MRI investigate if there are any blood tests that can predict condition patients. METHODS:A retrospective, cross-sectional was conducted on 46 patients who...

Background A hyper-intense vessel sign on fluid attenuated inversion recovery magnetic resonance imaging (FHV) represents slow blood flow in the cerebral arteries. Purpose To investigate relationship between proximal FHV (pFHV) initial (MRI) and status of culprit (stenosis, obstruction) hyper-acute strokes affecting territory middle artery (MCA). Material Methods The study participants consisted 105 patients presenting to emergency department (ED) with acute MCA infarction within 4.5 h onset...

Aim. To determine whether the chest compression depth of at least 1/3 Anteroposterior (AP) diameter and about 5 cm is appropriate for children all age groups via computed tomography. Methods. The AP chest, anterior wall diameter, compressible (Cd) were measured lower half sternum patients aged 1-18 years using mean ratio to Cd adult was used as limit, 6 upper limit. Also, resulting in a residual <1 considered cause internal injury potentially. With limits, ratios compared when...

The online audience for newspapers continues to grow in both numbers and sophistication. However, most still offer all users the same content fail raise an individual user's satisfaction increase revenue newspaper company. Dynamic Dissemination of Digital Information (DDDI) system developed here provides personalized based on a preference. DDDI is hybrid application machine learning techniques, combined with Bayesian classification, neural clustering, matching. In addition, adopts...

Objective: This study was conducted to determine whether the presence and degree of left ventricular diastolic dysfunction (LVDD) can be predicted by simple computed tomography (CT)-measured atrial diameter (CTLAD).Methods: Among adult patients who underwent both chest CT imaging echocardiography in emergency department from January 2020 December 2021, a retrospective cross-sectional enrolled whom time interval between two tests <24 hours. Receiver operating characteristic (ROC) curve...

A cardiothoracic ratio ≥0.50 is widely used as an indicator of cardiomegaly, but associations between the and left ventricular systolic dysfunction (LVSD) have not been investigated previously. We conducted this study to investigate relationship measured using computed tomography (CT) ejection fraction (LVEF), determine optimal for predicting (LVSD).A retrospective cross-sectional was performed data from patients who underwent both chest CT echocardiography at emergency department January 1...

Patients suspected as having acute ischemic stroke usually undergo blood tests, including coagulation-related indexes, because thrombocytopenia and coagulopathy are contraindications for recombinant tissue plasminogen activator (rtPA) administration. We aimed to identify test indexes associated with symptomatic intracranial hemorrhage (sICH) in patients who received intravenous rtPA.This retrospective observational study included diagnosed were treated rtPA at the emergency department of a...

We investigated whether counting inflation breaths out loud during cardiopulmonary resuscitation (CPR) led to an earlier resumption of chest compressions.In this randomised controlled manikin simulation study, conducted from February 2015 April 2015, 32 fourth-year Korean medical students, equally divided into study and control groups, performed 10 cycles 15:2 CPR while administering using a bag mask. The first participant counted the number loud, second was told perform compressions as soon...

The purpose of this study was to assess if a modified airway (MA), developed by the authors, would act as guide and improve performance intubation when used with video stylet (VS) or fiberoptic bronchoscope (FOB) for endotracheal intubation.This randomized crossover simulation using manikins conducted 36 novice operators. Time complete intubation, time see glottis, success rate each device were measured compared without use MA.For FOB MA, median significantly reduced from 46 31 seconds...

We aimed to investigate the causes and clinical laboratory features of patients with ureteritis observed on intravenous contrast-enhanced abdominopelvic computed tomography (APCT) conducted in emergency department (ED).All APCTs ED from November 2017 2020 were investigated for presence ureteritis. The incidence ureteritis, presumed cause as well retrospectively analyzed.Ureteritis was 422 out 7,386 (5.7%) who underwent APCTs. two main reasons undergoing APCT abdominal pain (49%) infection...

The current guidelines for the diagnosis of acute pyelonephritis (APN) recommend that APN be diagnosed based on clinical features and presence pyuria. However, we observed some patients who are with do not have characteristic or pyuria at initial examination. We performed this study to investigate characteristics without pyuria.A retrospective, cross-sectional was conducted 391 radiologic findings, between 2015 2019. features, laboratory results, computed tomography (CT) findings were...
