Purpose To test the predictive value of skewness and kurtosis changes normalized cerebral blood volume (nCBV) during early treatment period for differentiating tumor progression from pseudoprogression in patients with newly diagnosed glioblastomas. Materials Methods The institutional review board approved this retrospective study. authors assessed 135 glioblastomas who underwent concurrent chemotherapy radiation therapy (CCRT) after surgical resection. Patients developed new or enlarged...
The purpose of this study is to understand interrelationships among culinary employees' perception role stress, burnout, and turnover intent in a deluxe hotel. A total 316 employees Korea participated the study. results showed positive relationship between perceptions stress burnout. Participants who reported high level burnout were more likely leave their position. In addition, there moderating effects related tenure causal relationships intent. Limitations future research directions are...
This study applies experiential value, satisfaction, brand love, loyalty, and generation to identify consumer behavior toward robot baristas providing new non-face-to-face services during the COVID-19 pandemic. For analysis, a set of hypotheses was developed tested based on data collected from 404 customers who had visited barista coffee shop (RBCS) in South Korea. The results show that playfulness most positive effect followed by service excellence return investment (CROI). Satisfaction...
To evaluate whether artificial intelligence (AI) for detecting breast cancer on mammography can improve the performance and time efficiency of radiologists reading mammograms.A commercial deep learning-based software was validated using external data collected from 200 patients, 100 each with without (40 benign lesions 60 lesions) one hospital. Ten readers, including five specialist (BSRs) general (GRs), assessed all images a seven-point scale to rate likelihood malignancy in two sessions,...
Objective:To analyze the diagnostic accuracy and trend in screening mammography Korea. Materials Methods:We retrospectively linked information from hospitals participating Alliance of Breast Cancer Screening Korea (ABCS-K) database National Program.We calculated performance indicators, including recall rate, cancer detection rate (CDR), positive predictive value (PPV), sensitivity, specificity, false-positive (FPR), interval (ICR).Changes indicators were as annual percent change with 95%...
This study aimed to investigate the feasibility of using artificial intelligence (AI) identify normal chest radiography (CXR) from worklist radiologists in a health-screening environment.This retrospective simulation was conducted CXRs 5887 adults (mean age ± standard deviation, 55.4 11.8 years; male, 4329) three health screening centers South Korea commercial AI (Lunit INSIGHT CXR3, version 3.5.8.8). Three board-certified thoracic reviewed CXR images for referable abnormalities and grouped...
Although core needle biopsy was introduced as a diagnostic alternative to fine-needle aspiration, the utility and safety of for thyroid nodules in large population has yet be studied comprehensively. We evaluate yields on large-scale basis investigate its potential preliminary diagnosis nodules.Between March 2005 December 2013, 2448 initially detected from 2120 consecutive patients who underwent were retrospectively evaluated. Of these, 72 63 excluded due prior aspiration attempts. The...
Abstract Traditional regression-based approaches do not provide good results in diagnosis and prediction of occurrences cardiovascular diseases (CVD). Therefore, the goal this paper is to propose a deep learning–based model occurrence major adverse cardiac events (MACE) during 1, 6, 12 month follow-up after hospital admission acute myocardial infarction (AMI) patients using knowledge mining. We used Korea Acute Myocardial Infarction Registry (KAMIR) dataset, disease database registered 52...
Purpose The primary purpose of this article is to develop and test a model the antecedents consequences (Cho et al., 2016) bullying in Korean hotel kitchens. Design/methodology/approach Cross-sectional survey data were collected from 288 kitchen workers at 12 upscale hotels. Proposed path models tested using Hayes' (2013) PROCESS syntax SPSS for mediation moderated analyses. Findings empirical results indicated that an employee's acquiescent silence behavior increases likelihood being...
Traumatic neuroma may be easily confused with recurrent lymphadenopathy in the neck, causing patient anxiety, need for fine-needle aspiration (FNA), and even surgery. The purpose of this study was to evaluate ultrasound (US) features that differentiate traumatic from after lateral neck dissection (LND), focusing on direct continuity involved nerve.This compared US 56 neuromas 36 consecutive patients, lymphadenopathies 34 patients who had a previous history total thyroidectomy LND thyroid...
Objective:To analyze participant factors that affect the diagnostic performance of screening mammography.Materials and Methods: We enrolled 128756 cases from 10 hospitals between 2005 2010.We analyzed recall rate, cancer detection rate (CDR) per 1000 examinations, positive predictive value (PPV), sensitivity, specificity, false (FPR), interval (ICR) negative examinations according to including age, breast density, number visit same institution, adjusted for confounding variables.Results:...
This paper describes an improving method for solving localization problems with a highly accurate model of mobile robot either in uncertainly large-scale environment. Firstly, we motivate our approach by analyzing intensively the dead-reckoning tricycle type. Secondly, propose algorithm based on Hybrid Extended Kalman Filter using artificial beacons. In this paper, 360° sensor scan is used each observation and odometry data updated to estimate position. Then comparison between real estimated...
Ultrasonography (renamed from the Journal of Korean Society Ultrasound in Medicine January 2014), official English-language journal (KSUM), is an international peer-reviewed academic dedicated to practice, research, technology, and education dealing with medical ultrasound, Aims Scope:Ultrasonography ultrasound.It published four times per year: 1, April July October 1. Original articles, topical reviews, pictorial essays, notable case reports are covering state-of-the-art content. also...
Abstract Purpose The objective of this study was to compare the false negative rate, sensitivity and positive rate ultrasound (US)‐guided fine needle aspiration (FNA) with those US‐guided core biopsy (CNB) for large thyroid nodules ≥2.0 cm, which reportedly have an increased risk malignancy. Methods We retrospectively studied surgically confirmed that had preoperative FNA or CNB between March 2005 December 2013. reviewed nodule size, sonographic features, cytohistologic results, final...
