| ○ | ○ | Article | Development of Worth Estimation and Key Target Selection Methods for Effective VE | VE is a powerful technique for analyzing a design with a focus on functionality, reducing costs, and increasing value. However, in order to proceed with the design of VE, the theoretical basis for the VE target selection process, which must be preceded in the preparation stage, is lacking, and as a result, it is difficult to verify the most effective target selection. Thus, a theoretical basis is needed. In this study, we intend to quantify the "Worth" value of the "Cost to Worth" technique and present an objective model of the target selection method using the derived value index (VI). For this purpose, cost worth (Worth C) was calculated based on the performance data of 1008 cases for 15 building types provided by the Domestic Public Procurement Service and the share of 83 detailed processes in seven fields. Then, a survey was conducted targeting the ordering companies, and the final worth (Worth F) was calculated by multiplying the derived customer value (Worth V) weight for each detailed work type. We calculated the value index (VI) by comparing "Cost" and "Worth F" for each detailed construction type of the VE project and developed a model to select construction types that exceed the VI standard value derived using the standard error of the population. Both cost experts and non-cost experts can use the developed model to specify the VE target selection criteria in order to easily select the key target, objectively sort the values that serve as the basis for calculating the value index, and make it possible to more easily select the VE target selection criteria based on theoretical evidence. Also, the model can be used to obtain effective detailed design VE results. | Jeong, Yeon-Goo; Jeong, Hye-Min; Kim, Byung-Soo | Kyungpook Natl Univ, Dept Civil Engn, 80 Daehakro, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Architectural Engn, 80 Daehakro, Daegu 41566, South Korea | 59148740600; 59148637400; 57013677400 | jygp0907@hanmail.net;jhm6076@gmail.com;bskim65@knu.ac.kr; | BUILDINGS | BUILDINGS-BASEL | 2075-5309 | 14 | 5 | SCIE | CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL | 2024 | 3.1 | 32.1 | 0 | 2025-05-07 | 0 | 0 | public buildings; cost to worth; worth; VI; key targets selection | cost to worth; key targets selection; public buildings; VI; worth | Cost to worth; Key target selection; Objective models; Public buildings; Reducing costs; Selection criteria; Selection methods; Targets selection; Value indices; Worth; Structural design | English | 2024 | 2024-05 | 10.3390/buildings14051235 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Experimental and Analytical Study on Non-Damaged Reinforcement Method for Pipe Rack Steel Structures | Pipe racks are steel structures that support various pipes transporting materials in industrial complexes. The pipes on pipe racks may transport hazardous substances, which imposes limitations on their structural reinforcement. Therefore, this study aimed to propose methods for reinforcing the joints of pipe rack structures through non-welding and non-drilling techniques. The joints of pipe rack structures were connected by end plates. Initially, this study evaluated the capacity of existing end plates in a real-world experiment and conducted cyclic loading tests with two additional reinforcement methods to validate their performance. Finally, finite element analysis was conducted to explore additional variables that were not covered in the experiments, and the optimal reinforcement method that demonstrated the best performance was proposed. | Lee, Jun-Seop; Shin, Kyung-Jae; Woo, Jong-Hun | Kyungpook Natl Univ, Reg Ctr Land Infrastruct & Transport Technol, Daegu 41566, South Korea | 57221623386; 59510719600; 57210344487 | kore6987@knu.ac.kr;shin@knu.ac.kr;wdusdka@knu.ac.kr; | BUILDINGS | BUILDINGS-BASEL | 2075-5309 | 14 | 9 | SCIE | CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL | 2024 | 3.1 | 32.1 | 0 | 2025-05-07 | 0 | 0 | pipe rack; end plate; steel reinforcement method; FEA | PLATE MOMENT CONNECTIONS; PANEL ZONE; BEHAVIOR; PERFORMANCE; EARTHQUAKE | end plate; FEA; pipe rack; steel reinforcement method | Cast iron pipe; Pipe joints; Reinforcement; Steel pipe; Welded steel structures; Analytical studies; Endplates; Industrial complex; Performance; Pipe rack; Rack structures; Reinforcement method; Steel reinforcement method; Steel reinforcements; Transporting materials; Plates (structural components) | English | 2024 | 2024-09 | 10.3390/buildings14092637 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Exploring Cost Variability and Risk Management Optimization in Natural Disaster Prevention Projects | The purpose of this study is to analyze the causes of cost variation in natural disaster prevention projects (NDPPs) in Gyeongsangbuk-do, South Korea, and develop tailored cost and risk management strategies. Utilizing a binary logistic regression model, this research uniquely focuses on the Gyeongsangbuk-do region, gathering data from 244 stakeholders through an online survey. The study identifies critical variables influencing cost deviation, including project management risk (PMR), project costing and execution risk (PCER), project execution strategy risk (PESR), construction project risk (CPR), project cost and schedule risk (PCSR), project management challenges (PMCs), and construction project subcontractor and safety management (CPSSM). Significant findings revealed PMR (OR = 3.744, 95% C.I. [1.657, 8.457]), PCER (OR = 5.068, 95% C.I. [2.236, 11.484]), and PESR (OR = 3.447, 95% C.I. [1.853, 6.413]) as the primary causes of cost deviation, alongside the notable impacts of other factors such as CPSSM. The developed predictive model is instrumental for NDPP stakeholders in Gyeongsangbuk-do, providing advanced risk management capabilities and aiding in effective preventive measures. This study not only corroborates theoretical hypotheses from previous research but also offers new insights into cost deviation causes in NDPPs, thereby enhancing strategic decision-making and advancing risk management perspectives. | Cho, Jin-Ho; Shin, Young-Su; Kim, Jae-June; Kim, Byung-Soo | Kyungpook Natl Univ, Dept Ctr Intelligent Construct Automat, 80 Daehakro, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Law Sch, 80 Daehakro, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Civil Engn, 80 Daehakro, Daegu 41566, South Korea | 57469331000; 56626639300; 58903761100; 57013677400 | chojinho36@gmail.com;shinys@knu.ac.kr;jaejune.kim@daum.net;bskim65@knu.ac.kr; | BUILDINGS | BUILDINGS-BASEL | 2075-5309 | 14 | 2 | SCIE | CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL | 2024 | 3.1 | 32.1 | 1.25 | 2025-05-07 | 2 | 3 | natural disaster prevention projects; cost deviation; binary logistic regression; risk management strategy; project management optimization | binary logistic regression; cost deviation; natural disaster prevention projects; project management optimization; risk management strategy | Costs; Decision making; Disasters; Logistic regression; Project management; Risk assessment; Risk management; Binary logistic regression; Cost deviation; Management risk; Natural disaster prevention project; Natural disasters; Optimisations; Project execution; Project management optimization; Risk management strategies; Risks management; Disaster prevention | English | 2024 | 2024-02 | 10.3390/buildings14020391 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Methods for Selecting Design Alternatives through Integrated Analysis of Energy Performance of Buildings and the Physiological Responses of Occupants | We propose a technique that allows designers to develop energy-efficient buildings focused on occupants from the early design stage. The technique integrates the physiological responses of occupants and the energy performance of buildings. Among the architectural design elements, we considered the aspect ratio, ceiling height, and window-to-wall ratio as design variables and created 30 design alternatives for a single-occupancy room in a postpartum care center. These design alternatives were recreated in virtual reality, allowing 33 female participants to immerse themselves in the designed rooms. During the experiment, we collected electroencephalography (EEG) data from the participants. Furthermore, we used DesignBuilder to simulate 30 design alternatives and calculated the primary energy consumption per unit area for each alternative. By integrating the EEG data and energy performance analysis, we identified the design alternative among the 30 options that positively influenced the physiological responses of occupants while also being energy efficient. The selected alternative was designed with an aspect ratio of 1:1.6, a ceiling height of 2.3 m, and a window-to-wall ratio of 60%. This research represents a creative exploration that demonstrates how studies combining human physiological responses and architecture can evolve through integration with other subjects. Our findings provide a robust framework to explore the relationship between physiological responses and energy optimization for detailed architectural design elements. | Kim, Sanghee; Ryu, Jihye; Lee, Yujeong; Park, Hyejin; Lee, Kweonhyoung | Kyungpook Natl Univ, Sch Architecture, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Convergence Inst Construct Environm & Energy Engn, Daegu 41566, South Korea; Dong Eui Univ, Major Architecture, Busan 47340, South Korea; Kyungpook Natl Univ, A3 Architectural Lab, Daegu 41566, South Korea | 57222484247; 56192651000; 58738917200; 57226002455; 56726955000 | sangheekim@knu.ac.kr;ryou0407@knu.ac.kr;leeujeong0@gmail.com;phj8598@knu.ac.kr;idleekh@deu.ac.kr; | BUILDINGS | BUILDINGS-BASEL | 2075-5309 | 14 | 1 | SCIE | CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL | 2024 | 3.1 | 32.1 | 1.38 | 2025-04-16 | 3 | 3 | early architectural design; energy performance; occupant physiological response; virtual reality; EEG; DesignBuilder | STAGE; OPTIMIZATION; SIMULATION; WINDOW; SPACES; SHAPE | DesignBuilder; early architectural design; EEG; energy performance; occupant physiological response; virtual reality | Aspect ratio; Electroencephalography; Electrophysiology; Energy efficiency; Energy utilization; Physiological models; Thermal comfort; Virtual reality; Walls (structural partitions); Aspect-ratio; Ceiling height; Design alternatives; Design elements; Designbuilder; Early architectural design; Energy performance; Energy performance of buildings; Occupant physiological response; Physiological response; Architectural design | English | 2024 | 2024-01 | 10.3390/buildings14010237 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article; Retracted Publication | RETRACTED: Enhancing Data Quality Management in Structural Health Monitoring through Irregular Time-Series Data Anomaly Detection Using IoT Sensors (Retracted Article) | The importance of monitoring in assessing structural safety and durability continues to grow. With recent technological advancements, Internet of Things (IoT) sensors have garnered attention for their complex scalability and varied detection capabilities, becoming essential devices for monitoring. However, during the data collection process of IoT sensors, anomalies arise due to network instability, sensor noise, and malfunctions, degrading data quality and compromising monitoring system reliability. In this study, Interquartile Range (IQR), Long Short-Term Memory Autoencoder (LSTM-AE), and time-series decomposition were employed for anomaly detection in Structural Health Monitoring (SHM) processes. IQR and LSTM-AE produce irregular patterns; however, time-series decomposition effectively detects such anomalies. In road monitoring influenced by weather and traffic, the time-series decomposition approach is expected to play a crucial role in enhancing monitoring accuracy. | Cho, Junhwi; Lim, Kyoung Jae; Kim, Jonggun; Shin, Yongchul; Park, Youn Shik; Yeon, Jaeheum | Kangwon Natl Univ, Dept Reg Infrastruct Engn, Chunchon 24341, South Korea; Kyungpook Natl Univ, Dept Agr Civil Engn, Daegu 41566, South Korea; Kongju Natl Univ, Dept Rural Construct Engn, Yesan 32439, South Korea | Yeon, Jaeheum/AAC-5073-2019 | 58519202500; 35176071700; 35435507500; 55659438100; 56128581100; 57188756067 | xnxlwnsgnl@kangwon.ac.kr;kjlim@kangwon.ac.kr;jgkim@kangwon.ac.kr;ycshin@knu.ac.kr;park397@kongju.ac.kr;jyeon@kangwon.ac.kr; | BUILDINGS | BUILDINGS-BASEL | 2075-5309 | 14 | 7 | SCIE | CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL | 2024 | 3.1 | 32.1 | 0.35 | 2025-05-07 | 1 | 1 | structural health monitoring; IoT sensors; time-series data; anomaly detection; irregular data patterns | CONCRETE; SYSTEM; BRIDGE | anomaly detection; IoT sensors; irregular data patterns; structural health monitoring; time-series data | Anomaly detection; Long short-term memory; Quality management; Structural health monitoring; Time series; Anomaly detection; Auto encoders; Data patterns; Data quality management; Inter quartile ranges; Internet of thing sensor; Irregular data; Irregular data pattern; Time series decomposition; Time-series data; Internet of things | English | 2024 | 2024-07 | 10.3390/buildings14072223 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Shear Behavior of High-Strength and Lightweight Cementitious Composites Containing Hollow Glass Microspheres and Carbon Nanotubes | In this study, an experimental program was conducted to investigate the shear behavior of beams made of high-strength and lightweight cementitious composites (HS-LWCCs) containing hollow glass microspheres and carbon nanotubes. The compressive strength and dry density of the HS-LWCCs were 87.8 MPa and1.52 t/m3, respectively. To investigate their shear behavior, HS-LWCC beams with longitudinal rebars were fabricated. In this test program, the longitudinal and shear reinforcement ratios were considered as the test variables. The HS-LWCC beams were compared with ordinary high-strength concrete (HSC) beams with a compressive strength of 89.3 MPa to determine their differences; the beams had the same reinforcement configuration. The test results indicated that the initial stiffness and shear capacity of the HS-LWCC beams were lower than those of the HSC beams. These results suggested that the low shear resistance of the HS-LWCC beams led to brittle failure. This was attributed to the beams' low elastic modulus under compression and the absence of a coarse aggregate. Furthermore, the difference in the shear capacity of the HSC and HS-LWCC beams slightly decreased as the shear reinforcement ratio increased. The diagonal compression strut angle and diagonal crack angle of the HS-LWCC beams with shear reinforcement were more inclined than those of the HSC beams. This indicated that the lower shear resistance of the HS-LWCCs could be more effectively compensated for when shear reinforcement is provided and the diagonal crack angle is more inclined. The ultimate shear capacities measured in the tests were compared with various shear design provisions, including those of ACI-318, EC2, and CSA A23.3. This comparison showed that the current shear design provisions considerably overestimate the contribution of concrete to the shear capacity of HS-LWCC beams. | Lee, Dongmin; Lee, Seong-Cheol; Kwon, Oh-Sung; Yoo, Sung-Won | Kyungpook Natl Univ, Dept Civil Engn, 80 Daehak Ro, Daegu 41566, South Korea; Univ Toronto, Dept Civil & Mineral Engn, 35 St George St, Toronto, ON M5S 1A4, Canada; Gachon Univ, Dept Civil & Environm Engn, 1342 Seongnamdae Ro, Seongnam 13120, South Korea | Kwon, Oh-Sung/ABB-6825-2020; Kwon, Oh-Sung/H-1059-2013 | 57670923900; 35784449900; 56459431700; 56532969900 | knucon@naver.com;seonglee@knu.ac.kr;os.kwon@utoronto.ca;imysw@gachon.ac.kr; | BUILDINGS | BUILDINGS-BASEL | 2075-5309 | 14 | 9 | SCIE | CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL | 2024 | 3.1 | 32.1 | 0.42 | 2025-05-07 | 1 | 1 | crack angle; high-strength concrete; lightweight concrete; shear behavior; shear design | REINFORCED-CONCRETE BEAMS; TRANSVERSE REINFORCEMENT; MECHANICAL-PROPERTIES; FAILURES; MEMBERS; SIZE | crack angle; high-strength concrete; lightweight concrete; shear behavior; shear design | Carbon carbon composites; Compressive strength; Concrete aggregates; Concrete beams and girders; Microspheres; Shear strength; Cementitious composites; Composite beam; Crack angles; High strength concretes; High-strength; High-strength concrete beams; Lightweight concrete; Shear behaviour; Shear design; Shear reinforcement; Cracks | English | 2024 | 2024-09 | 10.3390/buildings14092824 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Assessment of deep learning image reconstruction (DLIR) on image quality in pediatric cardiac CT datasets type of manuscript: Original research | Bakground To evaluate the quantitative and qualitative image quality using deep learning image reconstruction (DLIR) of pediatric cardiac computed tomography (CT) compared with conventional image reconstruction methods. Methods Between January 2020 and December 2022, 109 pediatric cardiac CT scans were included in this study. The CT scans were reconstructed using an adaptive statistical iterative reconstruction-V (ASiR-V) with a blending factor of 80% and three levels of DLIR with TrueFidelity (low-, medium-, and high-strength settings). Quantitative image quality was measured using signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR). The edge rise distance (ERD) and angle between 25% and 75% of the line density profile were drawn to evaluate sharpness. Qualitative image quality was assessed using visual grading analysis scores. Results A gradual improvement in the SNR and CNR was noted among the strength levels of the DLIR in sequence from low to high. Compared to ASiR-V, high-level DLIR showed significantly improved SNR and CNR (P<0.05). ERD decreased with increasing angle as the level of DLIR increased. Conclusion High-level DLIR showed improved SNR and CNR compared to ASiR-V, with better sharpness on pediatric cardiac CT scans. | Cho, Hyun-Hae; Lee, So Mi; You, Sun Kyoung | Ewha Womans Univ, Seoul Hosp, Coll Med, Dept Radiol, Seoul, South Korea; Ewha Womans Univ, Seoul Hosp, Med Res Inst, Coll Med, Seoul, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Radiol, Daegu, South Korea; Chungnam Natl Univ Hosp, Dept Radiol, Daejeon, South Korea | 56544900900; 56824903400; 56710939300 | picoai@yahoo.co.kr; | PLOS ONE | PLOS ONE | 1932-6203 | 19 | 8 | SCIE | MULTIDISCIPLINARY SCIENCES | 2024 | 2.6 | 32.2 | 0.41 | 2025-05-07 | 1 | 1 | CONGENITAL HEART-DISEASE; ITERATIVE RECONSTRUCTION; COMPUTED-TOMOGRAPHY; ANGIOGRAPHY | Adolescent; Child; Child, Preschool; Deep Learning; Female; Heart; Humans; Image Processing, Computer-Assisted; Infant; Infant, Newborn; Male; Radiographic Image Interpretation, Computer-Assisted; Signal-To-Noise Ratio; Tomography, X-Ray Computed; adaptive statistical iterative reconstruction; adult; article; child; clinical article; computer assisted tomography; contrast to noise ratio; controlled study; deep learning; diagnosis; female; human; image quality; image reconstruction; intravenous drug administration; male; retrospective study; signal noise ratio; adolescent; computer assisted diagnosis; diagnostic imaging; heart; image processing; infant; newborn; preschool child; procedures; signal noise ratio; x-ray computed tomography | English | 2024 | 2024-08-26 | 10.1371/journal.pone.0300090 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | Article | Association between hemoglobin trajectories and the incidence of dementia in a cohort of females aged 55-79 years | Purpose To assess the association between pattern changes in hemoglobin levels over time and the incidence of dementia using trajectories in females aged 55-79 years.Materials and methods We conducted a retrospective cohort study using females of aged 55-79 years from the National Health Insurance Service National Health Screening Cohort in Korea. To identify hemoglobin trajectories over eight years (2002-2009), we performed a three-step approach comprising measures of change, factor analysis, and cluster analysis. Univariate and multivariate Cox proportional hazard models were used to assess the associations between hemoglobin trajectories and the incidence of dementia.Results We included 20,195 of 235,742 female participants. New dementia (N = 2664) was developed during follow-up period (2010-2015). Five hemoglobin trajectories were identified: high, mid, low, increasing, and decreasing. With high as a reference, the hazard ratios (HRs) for low and decreasing trajectories were significant, 1.28 (95% confidence interval [CI], 1.13-1.45) and 1.21 (95% CI, 1.10-1.34) in univariate models, respectively. However, only the HR for the decreasing trajectory was significant, 1.12 (95% CI, 1.01-1.24) after adjustment for confounders.Conclusion The decreasing trajectory of hemoglobin levels within the normal range was associated with dementia. Even females aged 55-79 years without anemia might be vulnerable to dementia development risk. | Lee, Dong Yoon; Jeong, Jihyeon; Choi, Won-Il | Hanyang Univ, Myongji Hosp, Dept Internal Med, Goyang, South Korea; Kyungpook Univ, Dept Stat, Daegu, South Korea; Hanyang Univ, Dept Publ Hlth Sci, Grad Sch, Seoul, South Korea | Lee, DongYoon/KFR-2934-2024 | yardsticklee@gmail.com; | PLOS ONE | PLOS ONE | 1932-6203 | 19 | 4 | SCIE | MULTIDISCIPLINARY SCIENCES | 2024 | 2.6 | 32.2 | 1 | COGNITIVE IMPAIRMENT; ANEMIA; RISK; EPIDEMIOLOGY; CHOLESTEROL; PREVALENCE; DISEASE; KOREA | English | 2024 | 2024-04-03 | 10.1371/journal.pone.0300784 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | ○ | Article | Comparative study between biliary covered self-expandable metal stent and conventional endoscopic bile drainage treatment in endoscopic retrograde cholangiopancreatography-related Stapfer type II retroperitoneal perforations | Background Perforation is one of the most serious complications of endoscopic retrograde cholangiopancreatography (ERCP). Conventional nonsurgical endoscopic treatments including intravenous antibiotic administration and plastic endoscopic biliary drainage are generally approved for the treatment of ERCP-related Stapfer type II perforation (perivaterian type). Biliary covered metal stent placement has recently been reported to have favorable outcomes in ERCP-related Stapfer type II perforations. We aimed to compare the outcomes of conventional endoscopic bile drainage and biliary covered self-expandable metal stent (SEMS) insertion in patients with Stapfer type II perforation.Methods Medical records of patients who underwent ERCP at Kyungpook National University Hospital in Daegu from 2011 to 2022 were retrospectively reviewed.Results A total of 8,402 ERCP procedures were performed in our hospital. Sixty-six ERCP-related perforations (0.78%) were identified. Among them, 37 patients (56.1%) who had Stapfer type II perforations were enrolled. Thirteen and twenty-four patients received biliary covered SEMS insertion and conventional endoscopic bile drainage treatments, respectively. No significant differences were observed in the clinical success rate (92.3% vs. 91.7%, p = 1.000), hospital stay (9.46 +/- 5.97 vs. 13.9 +/- 13.2 days, p = 0.258), and post-ERCP-related fasting time (5.4 +/- 3.4 vs 4.3 +/- 3.0 days, p = 0.305). Complications including bleeding, post-ERCP pancreatitis, fever, and death were not significantly different between the two groups. The conventional endoscopic bile drainage group took less time for ERCP than the SEMS group (11.5 +/- 5.2 vs. 18.5 +/- 11.2 min, p = 0.013).Conclusions Compared with the conventional endoscopic bile drainage treatment method, biliary covered SEMS did not improve patient outcomes in ERCP-related Stapfer type II perforations. | Heo, Jun; Jung, Min Kyu; Lee, Jieun; Lee, Dong wook; Cho, Chang Min; Cha, Jung Guen | Kyungpook Natl Univ, Sch Med, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Radiol, Daegu, South Korea | KANG, MIN KYU/ACI-8824-2022 | 36448170600; 56783168100; 57195958819; 57202974895; 57158287600; 57206855971 | minky1973@knu.ac.kr; | PLOS ONE | PLOS ONE | 1932-6203 | 19 | 3 | SCIE | MULTIDISCIPLINARY SCIENCES | 2024 | 2.6 | 32.2 | 0.41 | 2025-05-07 | 1 | 1 | DUODENAL PERFORATION; RISK-FACTORS; MANAGEMENT; ERCP; SPHINCTEROTOMY | Bile; Cholangiopancreatography, Endoscopic Retrograde; Drainage; Humans; Retrospective Studies; Stents; Treatment Outcome; abdominal pain; adult; aged; Article; balloon dilatation; biliary tract drainage; bleeding; cholangitis; clinical outcome; common bile duct stone; comparative study; controlled study; endoscopic retrograde cholangiopancreatography; endoscopic sphincterotomy; female; fever; fluoroscopy; heart arrest; hospital patient; hospitalization; human; intensive care; male; middle aged; myelodysplastic syndrome; pancreatitis; percutaneous transhepatic drainage; perforation; resuscitation; Stapfer type II retroperitoneal perforation; bile; procedures; retrospective study; treatment outcome | English | 2024 | 2024-03-12 | 10.1371/journal.pone.0300029 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Deep learning algorithm for the automated detection and classification of nasal cavity mass in nasal endoscopic images | Nasal endoscopy is routinely performed to distinguish the pathological types of masses. There is a lack of studies on deep learning algorithms for discriminating a wide range of endoscopic nasal cavity mass lesions. Therefore, we aimed to develop an endoscopic-examination-based deep learning model to detect and classify nasal cavity mass lesions, including nasal polyps (NPs), benign tumors, and malignant tumors. The clinical feasibility of the model was evaluated by comparing the results to those of manual assessment. Biopsy-confirmed nasal endoscopic images were obtained from 17 hospitals in South Korea. Here, 400 images were used for the test set. The training and validation datasets consisted of 149,043 normal nasal cavity, 311,043 NP, 9,271 benign tumor, and 5,323 malignant tumor lesion images. The proposed Xception architecture achieved an overall accuracy of 0.792 with the following class accuracies on the test set: normal = 0.978 +/- 0.016, NP = 0.790 +/- 0.016, benign = 0.708 +/- 0.100, and malignant = 0.698 +/- 0.116. With an average area under the receiver operating characteristic curve (AUC) of 0.947, the AUC values and F1 score were highest in the order of normal, NP, malignant tumor, and benign tumor classes. The classification performances of the proposed model were comparable with those of manual assessment in the normal and NP classes. The proposed model outperformed manual assessment in the benign and malignant tumor classes (sensitivities of 0.708 +/- 0.100 vs. 0.549 +/- 0.172, 0.698 +/- 0.116 vs. 0.518 +/- 0.153, respectively). In urgent (malignant) versus nonurgent binary predictions, the deep learning model achieved superior diagnostic accuracy. The developed model based on endoscopic images achieved satisfactory performance in classifying four classes of nasal cavity mass lesions, namely normal, NP, benign tumor, and malignant tumor. The developed model can therefore be used to screen nasal cavity lesions accurately and rapidly. | Kwon, Kyung Won; Park, Seong Hyeon; Lee, Dong Hoon; Kim, Dong-Young; Park, Il-Ho; Cho, Hyun-Jin; Kim, Jong Seung; Kim, Joo Yeon; Hong, Sang Duk; Kim, Shin Ae; Yoo, Shin Hyuk; Park, Soo Kyoung; Heo, Sung Jae; Kim, Sung Hee; Won, Tae-Bin; Choi, Woo Ri; Kim, Yong Min; Kim, Yong Wan; Kim, Jong-Yeup; Kwon, Jae Hwan; Yu, Myeong Sang | Sungkyunkwan Univ, Samsung Changwon Hosp, Dept Otolaryngol, Sch Med, Chang Won, South Korea; Konyang Univ, Coll Med, Dept Biomed Informat, Daejeon, South Korea; Chonnam Natl Univ, Dept Otolaryngol Head & Neck Surg, Med Sch, Hwasun, South Korea; Hwasun Hosp, Hwasun, South Korea; Seoul Natl Univ Hosp, Dept Otorhinolaryngol Head & Neck Surg, Seoul, South Korea; Korea Univ, Coll Med, Dept Otorhinolaryngol Head & Neck Surg, Guro Hosp, Seoul, South Korea; Gyeongsang Natl Univ, Sch Med, Dept Otorhinolaryngol, Jinju, South Korea; Gyeongsang Natl Univ Hosp, Jinju, South Korea; Jeonbuk Natl Univ, Coll Med, Dept Otorhinolaryngol Head & Neck Surg, Jeonju, South Korea; Kosin Univ, Coll Med, Dept Otolaryngol Head & Neck Surg, Busan, South Korea; Sungkyunkwan Univ, Sch Med, Dept Otorhinolaryngol Head & Neck Surg, Samsung Med Ctr, Seoul, South Korea; Soonchunhyang Univ, Coll Med, Dept Otolaryngol Head & Neck Surg, Seoul Hosp, Seoul, South Korea; Dankook Univ, Coll Med, Dept Otorhinolaryngol Head & Neck Surg, Cheonan, South Korea; Chungnam Natl Univ, Sejong Hosp, Coll Med, Dept Otorhinolaryngol Head & Neck Surg, Sejong, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Otorhinolaryngol Head & Neck Surg, Daegu, South Korea; Natl Med Ctr, Dept Otorhinolaryngol Head & Neck Surg, Seoul, South Korea; Seoul Natl Univ, Bundang Hosp, Dept Otorhinolaryngol Head & Neck Surg, Seongnam, South Korea; Chungnam Natl Univ, Coll Med, Dept Otorhinolaryngol Head & Neck Surg, Daejeon, South Korea; Inje Univ, Dept Otorhinolaryngol, Haeundae Paik Hosp, Busan, South Korea; Univ Ulsan, Coll Med, Asan Med Ctr, Dept Otorhinolaryngol Head & Neck Surg, Seoul, South Korea | ; Park, Il-Ho/AAI-1394-2019; Kim, Jong-Yeup/ISA-2120-2023; 허, 성재/AAU-3921-2020 | 58478930600; 58938465800; 55568531298; 56493287200; 7403243047; 57205203680; 57218494735; 55414725000; 24072844200; 9239080300; 57220743530; 57203275869; 55822906000; 57208644913; 21935553000; 57202982637; 55644003352; 57196171184; 55912024300; 55807257400; 35977162700 | dryums@gmail.com;entkwon@hanmail.net;jykim@kyuh.ac.kr; | PLOS ONE | PLOS ONE | 1932-6203 | 19 | 3 | SCIE | MULTIDISCIPLINARY SCIENCES | 2024 | 2.6 | 32.2 | 2.45 | 2025-05-07 | 8 | 8 | SINONASAL INVERTED PAPILLOMA; NETWORK; CANCER | Algorithms; Deep Learning; Endoscopy; Humans; Nasal Cavity; Neoplasms; Article; artificial neural network; benign neoplasm; deep learning; endoscopy; female; human; human tissue; image analysis; learning algorithm; machine learning; major clinical study; male; nose cavity; nose tumor; receiver operating characteristic; retrospective study; sensitivity and specificity; sinonasal polyp; support vector machine; algorithm; diagnostic imaging; endoscopy; neoplasm; nose cavity; procedures | English | 2024 | 2024-03-13 | 10.1371/journal.pone.0297536 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Diagnostic accuracy of dental caries detection using ensemble techniques in deep learning with intraoral camera images | Camera image-based deep learning (DL) techniques have achieved promising results in dental caries screening. To apply the intraoral camera image-based DL technique for dental caries detection and assess its diagnostic performance, we employed the ensemble technique in the image classification task. 2,682 intraoral camera images were used as the dataset for image classification according to dental caries presence and caries-lesion localization using DL models such as ResNet-50, Inception-v3, Inception-ResNet-v2, and Faster R-convolutional neural network according to diagnostic study design. 534 participants whose mean age [SD] was 47.67 [+/- 13.94] years were enrolled. The dataset was divided into training (56.0%), validation (14.0%), and test subset (30.0%) annotated by one experienced dentist as a reference standard about dental caries detection and lesion location. The confusion matrix, area under the receiver operating characteristic curve (AUROC), and average precision (AP) were evaluated for performance analysis. In the end-to-end dental caries image classification, the ensemble DL models had consistently improved performance, in which as the best results, the ensemble model of Inception-ResNet-v2 achieved 0.94 of AUROC and 0.97 of AP. On the other hand, the explainable model achieved 0.91 of AUROC and 0.96 of AP after the ensemble application. For dental caries classification using intraoral camera images, the application of ensemble techniques exhibited consistently improved performance regardless of the DL models. Furthermore, the trial to create an explainable DL model based on carious lesion detection yielded favorable results. | Kang, Sohee; Shon, Byungeun; Park, Eun Young; Jeong, Sungmoon; Kim, Eun-Kyong | Yeungnam Univ, Coll Med, Dept Dent, Daegu, South Korea; Kyungpook Natl Univ Hosp, Res Ctr Artificial Intelligence Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Med Informat, Daegu, South Korea; Kyungpook Natl Univ, Coll Sci & Technol, Dept Dent Hyg, Sangju, South Korea | 57874967700; 58635954000; 57188575494; 23100090400; 55915892100 | jinha01@naver.com; | PLOS ONE | PLOS ONE | 1932-6203 | 19 | 9 | SCIE | MULTIDISCIPLINARY SCIENCES | 2024 | 2.6 | 32.2 | 0.41 | 2025-05-07 | 0 | 2 | ASSESSMENT SYSTEM ICDAS; INTERNATIONAL CARIES; LESIONS; RESIN | Adult; Deep Learning; Dental Caries; Female; Humans; Image Processing, Computer-Assisted; Male; Middle Aged; Neural Networks, Computer; ROC Curve; accuracy; adult; Article; computer assisted tomography; cone beam computed tomography; deep learning; dental caries; dental restoration; female; human; image segmentation; machine learning; major clinical study; male; optical coherence tomography; receiver operating characteristic; task performance; tooth disease; visual information; artificial neural network; diagnosis; diagnostic imaging; image processing; middle aged; pathology; procedures | English | 2024 | 2024-09-06 | 10.1371/journal.pone.0310004 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Effects of team-based mixed reality simulation program in emergency situations | Background This study aimed to demonstrate the effectiveness of a team-based mixed reality simulation program about emergencies. Method A nonequivalent control group pretest-posttest design was utilized. We recruited 32 nurses for the experimental group and 32 for the control group, resulting in a total of 61 nurses ultimately included as subjects for analysis. This mixed reality program is designed to facilitate responses in cardiopulmonary resuscitation situations simultaneously using four HoloLens. With shared content visible to all four trainees, the participants could engage in simulation while freely communicating. The experimental group engaged in cardiopulmonary resuscitation emergency simulation while wearing the HoloLens, while the control group was provided with written CPR materials. Results There were significant increases in the experimental group's critical thinking (p < .001), learning transfer motivation (p = .006), communication confidence (p = .033), and learning immersion (p < .001) compared to the control group. Conclusion The program developed in this study presents an effective educational strategy that can enhance nurses' emergency competencies and leverage the practicality of mixed reality. | Choi, Moon-Ji; Kim, Kyeng-Jin | Kyungil Univ, Dept Nursing, Gyongsan, South Korea; Kyungpook Natl Univ, Coll Nursing, Daegu, South Korea | 57201942705; 57226488036 | kkjin@knu.ac.kr; | PLOS ONE | PLOS ONE | 1932-6203 | 19 | 2 | SCIE | MULTIDISCIPLINARY SCIENCES | 2024 | 2.6 | 32.2 | 0 | 2025-05-07 | 1 | 2 | NURSES; RESUSCITATION; GUIDELINES; ATTITUDES; VALIDITY; CPR | Augmented Reality; Communication; Computer Simulation; Control Groups; Humans; Learning; adult; Article; communication clarity; communication confidence; controlled study; critical thinking; decision making; electrocardiogram; emergency; emergency situation; female; human; human experiment; learning; learning immersion; Likert scale; male; nurse; nursing education; pretest posttest design; problem based learning; resuscitation; simulation training; team based mixed reality simulation program; transfer of learning; virtual reality; augmented reality; computer simulation; control group; interpersonal communication | English | 2024 | 2024-02-29 | 10.1371/journal.pone.0299832 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Efficacy and safety of three-dimensional magnetically assisted capsule endoscopy for upper gastrointestinal and small bowel examination | Background Magnetically assisted capsule endoscopy (MACE) showed the feasibility for upper gastrointestinal examination. To further enhance the performance of conventional MACE, it is necessary to provide quality-improved and three-dimensional images. The aim of this clinical study was to determine the efficacy and safety of novel three-dimensional MACE (3D MACE) for upper gastrointestinal and small bowel examination at once. Methods This was a prospective, single-center, non-randomized, and sequential examination study (KCT0007114) at Dongguk University Ilsan Hospital. Adult patients who visited for upper endoscopy were included. The study protocol was conducted in two stages. First, upper gastrointestinal examination was performed using 3D MACE, and a continuous small bowel examination was performed by conventional method of capsule endoscopy. Two hours later, an upper endoscopy was performed for comparison with 3D MACE examination. The primary outcome was confirmation of major gastric structures (esophagogastric junction, cardia/fundus, body, angle, antrum, and pylorus). Secondary outcomes were confirmation of esophagus and duodenal bulb, accuracy for gastric lesions, completion of small bowel examination, 3D image reconstruction of gastric lesion, and safety. Results Fifty-five patients were finally enrolled. The examination time of 3D MACE was 14.84 +/- 3.02 minutes and upper endoscopy was 5.22 +/- 2.39 minutes. The confirmation rate of the six major gastric structures was 98.6% in 3D MACE and 100% in upper endoscopy. Gastric lesions were identified in 43 patients during 3D MACE, and 40 patients during upper endoscopy (Sensitivity 0.97). 3D reconstructed images were acquired for all lesions inspected by 3D MACE. The continuous small bowel examination by 3D MACE was completed in 94.5%. 3D MACE showed better overall satisfaction (3D MACE 9.55 +/- 0.79 and upper endoscopy 7.75 +/- 2.34, p<0.0001). There were no aspiration or significant adverse event or capsule retention in the 3D MACE examination. Conclusions Novel 3D MACE system is more advanced diagnostic modality than the conventional MACE. And it is possible to perform serial upper gastrointestinal and small bowel examination as a non-invasive and one-step test. It would be also served as a bridge to pan-endoscopy. | Oh, Dong Jun; Lee, Yea Je; Kim, Sang Hoon; Chung, Joowon; Lee, Hyun Seok; Nam, Ji Hyung; Lim, Yun Jeong | Dongguk Univ, Ilsan Hosp, Dept Internal Med, Goyang, South Korea; Nowon Eulji Med Ctr, Dept Internal Med, Seoul, South Korea; Kyungpook Natl Univ Hosp, Dept Internal Med, Daegu, South Korea | ; LIM, Yun Jeong/KVY-6446-2024 | 57203029221; 58023468800; 57215900945; 57563445400; 36647886100; 42361607200; 56501161800 | drlimyj@gmail.com; | PLOS ONE | PLOS ONE | 1932-6203 | 19 | 5 | SCIE | MULTIDISCIPLINARY SCIENCES | 2024 | 2.6 | 32.2 | 0.41 | 2025-05-07 | 0 | 1 | CANCER SCREENING-PROGRAM; UPPER GI TRACT; GASTRIC-CANCER | Adult; Aged; Capsule Endoscopy; Female; Humans; Imaging, Three-Dimensional; Intestine, Small; Male; Middle Aged; Prospective Studies; Upper Gastrointestinal Tract; macrogol derivative; midazolam; propofol; simethicone; abdominal tenderness; adult; aged; anatomical concepts; Article; capsule endoscopy; controlled study; diagnostic test accuracy study; duodenal bulb; duodenum; dyspepsia; endoscopic ultrasonography; endoscopy; esophagus; female; follow up; gastrectomy; gastroesophageal junction; gastrointestinal tract examination; gastroscopy; human; image analysis; image reconstruction; intestine parameters; intestine transit time; major clinical study; male; measurement accuracy; outcome assessment; patient satisfaction; prospective study; pylorus; retention time; safety; sensitivity and specificity; small intestine; stomach cancer; stomach lesion; stomach polyp; stomach ulcer; three dimensional magnetically assisted capsule endoscopy; upper gastrointestinal tract; clinical trial; diagnostic imaging; middle aged; pathology; procedures; three-dimensional imaging; upper gastrointestinal tract | English | 2024 | 2024-05-07 | 10.1371/journal.pone.0295774 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Hybrid operating rooms and the risk of postoperative hypothermia in pregnant women with placenta previa: A retrospective cohort study | Background Births at advanced maternal ages (>= 35 years) are increasing. This has been associated with a higher incidence of placenta previa, which increases bleeding risk. Hybrid operating rooms, designed to accommodate interventions and cesarean sections, are becoming more prominent because of their dual capabilities and benefits. However, they have been associated with increased postoperative hypothermia in pediatric settings; moreover, this has not been studied in pregnant women with placenta previa. Methods This retrospective cohort study included pregnant women diagnosed with placenta previa who underwent elective cesarean section under general anesthesia between May 2019 and 2023. The patients were categorized according to the operating room type. The primary outcome was to determine whether the hybrid operating room is a risk factor for immediate postoperative hypothermia, defined as a tympanic membrane temperature below 36.0 degrees C. The secondary outcomes were the effects of immediate postoperative hypothermia on the durations of postanesthetic care unit and postoperative hospital stays and incidence of complications. Results Immediate postoperative hypothermia (tympanic membrane temperature < 36.0 degrees C) was more prevalent in the hybrid than in the standard operating room group (20% vs. 36.6%, p = 0.033), with a relative risk of 2.86 (95% confidence interval 1.24-6.64, p < 0.001). Patients undergoing surgery in the hybrid operating room who experienced immediate postoperative hypothermia stayed longer in the postanesthetic care unit (26 min vs. 40 min, p < 0.001) and in the hospital after surgery (4 days; range 3-5 vs. 4 days; range 4-11, p = 0.021). However, the complication rates of both groups were not significantly different (11.3% vs 7.3%, p = 0.743). Conclusion Hybrid operating rooms may increase the risk of postoperative hypothermia. Postoperative hypothermia is associated with prolonged postanesthetic care unit and hospital stays. Preventing hypothermia in patients in hybrid operating rooms is of utmost importance. | Lee, Sou Hyun; Lee, You Hyun | Kyungpook Natl Univ Hosp, Dept Anesthesiol & Pain Med, Daegu, South Korea; Keimyung Univ, Sch Med, Dongsan Med Ctr, Dept Ophthalmol, Daegu, South Korea | Lee, Sou Hyun/JAC-3771-2023; Lee, You Hyun/ISV-2828-2023 | 57223957892; 57191708556 | lyh8686@dsmc.or.kr; | PLOS ONE | PLOS ONE | 1932-6203 | 19 | 6 | SCIE | MULTIDISCIPLINARY SCIENCES | 2024 | 2.6 | 32.2 | 0 | 2025-05-07 | 0 | 0 | Adult; Anesthesia, General; Cesarean Section; Female; Humans; Hypothermia; Operating Rooms; Placenta Previa; Postoperative Complications; Pregnancy; Retrospective Studies; Risk Factors; fresh frozen plasma; midazolam; propofol; rocuronium; sevoflurane; suxamethonium; adult; Article; balloon occlusion; bispectral index; blood transfusion; body temperature; cesarean hysterectomy; cesarean section; cohort analysis; endotracheal intubation; female; general anesthesia; gestational age; hospitalization; human; hypothermia; incidence; length of stay; major clinical study; Modified Aldrete score; muscle relaxation; operation duration; outcome assessment; perioperative complication; placenta previa; postoperative complication; pregnant woman; retrospective study; risk factor; scoring system; adverse event; cesarean section; epidemiology; etiology; operating room; postoperative complication; pregnancy; risk factor; surgery | English | 2024 | 2024-06-25 | 10.1371/journal.pone.0305951 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
