| ○ | ○ | Article | Recyclable Magnetic MOF-Catalyzed Synthesis of 1-Aminoisoquinolines and 6-Aminophenanthridines from 5-(2-Bromoaryl)tetrazoles and 1,3-Diketones under Microwave Irradiation | In this study, 5-(2-bromoaryl)tetrazoles were reacted with 1,3-diketones in DMF in the presence of a catalytic amount of magnetic Cu-MOF-74 (Fe3O4@SiO2@Cu-MOF-74) and a base under microwave irradiation to yield the corresponding 1-aminoisoquinolines. The Fe3O4@SiO2@Cu-MOF-74 catalyst could be easily recovered from the reaction mixture and reused four times without any significant loss of catalytic activity. An initial copper-catalyzed C(sp2)-C(sp3) bond formation accompanied by retro-Claisen deacylative cyclocondensation (for acyclic 1,3-diketones) and direct cyclocondensation (for cyclohexane-1,3-diones) is proposed as a key reaction pathway for this process. Cyclohexanone-fused 1-aminoisoquinolines produced from the reaction between 5-(2-bromoaryl)tetrazoles and cyclohexane-1,3-diones could be aromatized into 6-aminophenanthridines via a one-pot sequential process involving reduction, dehydration, and oxidation. | Dao, Pham Duy Quang; Lee, Seong Weon; Lim, Ho-Jin; Cho, Chan Sik | Vietnam Acad Sci & Technol, Inst Appl Mat Sci, Ho Chi Minh City 700000, Vietnam; Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea | Dao, P.

| ○ | ○ | Article | Rivoceranib, a VEGFR-2 inhibitor, monotherapy in previously treated patients with advanced or metastatic gastric or gastroesophageal junction cancer (ANGEL study): an international, randomized, placebo-controlled, phase 3 trial | Background Rivoceranib is an oral, selective tyrosine kinase inhibitor of vascular endothelial growth factor receptor-2. ANGEL (NCT03042611) was a global, randomized, double-blinded, placebo-controlled, phase 3 study evaluating rivoceranib as 3rd-line or >= 4th-line therapy in patients with advanced/metastatic gastric or gastroesophageal junction (GEJ) cancer. Methods Patients had failed >= 2 lines of chemotherapy and were randomized 2:1 to rivoceranib 700 mg once daily or placebo with best supportive care. Primary endpoint: overall survival (OS) in the intention-to-treat population. Secondary endpoints: progression-free survival (PFS), objective response rate (ORR), and disease control rate (DCR) by blinded independent central review (BICR). Results In total, 460 patients (rivoceranib n = 308, placebo n = 152) were enrolled. OS was not statistically different for rivoceranib versus placebo (median 5.78 vs. 5.13 months; hazard ratio [HR] 0.93, 95% CI 0.74-1.15; p = 0.4724). PFS by BICR (median 2.83 vs. 1.77 months; HR 0.58, 95% CI 0.47-0.71; p = 4th-line therapy, OS (median 6.34 vs. 4.73 months; p = 0.0192) and PFS by BICR (median 3.52 vs. 1.71 months; p = 3 treatment-emergent adverse events with rivoceranib were hypertension (17.9%), anemia (10.4%), aspartate aminotransferase increased (9.4%), asthenia (8.5%), and proteinuria (7.5%). Conclusions This study did not meet its primary OS endpoint. Compared to placebo, rivoceranib improved PFS, ORR, and DCR. Rivoceranib also improved OS in a prespecified patient subgroup receiving >= 4th-line therapy. | Kang, Yoon-Koo; Ryu, Min-Hee; Di Bartolomeo, Maria; Chau, Ian; Yoon, Harry; Kim, Jong Gwang; Lee, Keun-Wook; Oh, Sang Chul; Takashima, Atsuo; Kryzhanivska, Anna; Chao, Yee; Evesque, Ludovic; Schenker, Michael; Mcginn, Arlo; Zhao, Yufan; Lee, Jennifer; Wyrwicz, Lucjan; Boku, Narikazu | Univ Ulsan, Dept Gastroenterol, Asan Med Ctr, Coll Med, 88 Olymp Ro 43 Gil, Seoul 05505, South Korea; Fdn IRCCS Ist Nazl Tumori, Milan, Italy; Royal Marsden Hosp, Sutton, England; Mayo Clin, Canc Ctr, Rochester, MN USA; Kyungpook Natl Univ, Chilgok Hosp, Daegu, South Korea; Seoul Natl Univ, Bundang Hosp, Seoul Natl Univ Coll Med, Dept Radiol, Songnam, South Korea; Korea Univ Guro Hosp, Seoul, South Korea; Natl Canc Ctr, Tokyo, Japan; Ivano Frankivsk Reg Clin Cardiol Ctr, Ivano Frankivsk, Ukraine; Taipei Vet Gen Hosp, Taipei, Taiwan; Ctr Antoine Lacassagne, Nice, France; Centrul Oncol Sf Nectarie, Sect Oncol Med, Craiova, Romania; Elevar Therapeut Inc, Ft Lee, NJ USA; Inst Im Marii Sklodowskiej Curie, Klinika Onkol & Radioterapii 1, Ctr Onkol, Warsaw, Poland | Di Bartolomeo, Maria/D-1655-2017; Kryzhanivska, Anna/ABG-4997-2020; Kang, Yoon-Koo/ABL-4264-2022; Schenker, Michael/AAD-6920-2022; Chau, Ian/ABC-2023-2020 | 7402784198; 7101754860; 57192340883; 14526721100; 53867574500; 59501049300; 35205887300; 55647062500; 24781455800; 57205724674; 7402865850; 36774191700; 14050923200; 6701515734; 58849982300; 58744354700; 6602585943; 55359026700 | ykkang@amc.seoul.kr; | GASTRIC CANCER | GASTRIC CANCER | 1436-3291 | 1436-3305 | 27 | 2 | SCIE | GASTROENTEROLOGY & HEPATOLOGY;ONCOLOGY | 2024 | 5.1 | 16.7 | 1.6 | 2025-05-07 | 3 | 6 | Stomach neoplasms; Tyrosine protein kinase inhibitors; Vascular endothelial growth factor receptor-2 | SELECTIVE INHIBITOR; DOUBLE-BLIND; ADENOCARCINOMA; APATINIB | Stomach neoplasms; Tyrosine protein kinase inhibitors; Vascular endothelial growth factor receptor-2 | Antineoplastic Combined Chemotherapy Protocols; Double-Blind Method; Esophagogastric Junction; Humans; Pyridines; Stomach Neoplasms; Vascular Endothelial Growth Factor A; Vascular Endothelial Growth Factor Receptor-2; placebo; rivoceranib; antineoplastic agent; pyridine derivative; rivoceranib; vasculotropin A; vasculotropin receptor 2; abdominal pain; adult; aged; anemia; Article; Asian; asthenia; cancer chemotherapy; controlled study; decreased appetite; diarrhea; disease control; double blind procedure; drug efficacy; drug safety; drug tolerability; fatigue; female; gastric junction cancer; gastric junction cancer; gastroesophageal junction cancer; gastroesophageal junction cancer; hand foot syndrome; human; hypertension; hypertransaminasemia; intention to treat analysis; major clinical study; male; middle aged; monotherapy; multicenter study; nausea; overall survival; patient care; phase 2 clinical trial; phase 3 clinical trial; population structure; progression free survival; proteinuria; randomized controlled trial; South Korea; stomach cancer; stomatitis; treatment failure; treatment outcome; United States; very elderly; clinical trial; gastroesophageal junction; pathology; stomach tumor | English | 2024 | 2024-03 | 10.1007/s10120-023-01455-5 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Silver tungstate-tellurite glass for radioactive iodine immobilization | The use of 235U as a fuel in nuclear power plants results in the formation of various fission products. Among them, 129I exhibits a long half-life (t1/2 = 15.7 million years) and tends to easily volatilize, making its capture and treatment necessary. In this study, silver tungstate-tellurite glass (Ag2O center dot WO3 center dot TeO2 with different mol% of AgI loading) was developed for radioactive iodine immobilization. The glass matrix was investigated by varying the fraction of Ag2O and/or WO3. AgI was added to each matrix, ranging from 0 to 40 mol% in increments of 10 mol %. The glass samples were prepared by the melt-quenching process at 850 degrees C for 90 min. X-ray fluorescence analysis indicated no significant loss of elements in the samples, whose amorphous phase was confirmed by X-ray diffraction analysis. The effects of increasing the amount of AgI on the glass matrix are discussed considering the results of X-ray photoelectron spectroscopy. The leaching properties of all samples were evaluated via the product consistency test-A. Finally, the normalized release of all elements satisfied the US regulation of 2 g/m2. | Shin, Seong-Sik; Kim, Ga-Yeong; Lee, Byeonggwan; Yang, Jae-Hwan; Son, Yeon-Su; Choi, Jung-Hoon; Pyo, Jae-Young; Lee, Ki Rak; Park, Hwan-Seo; Kang, Hyun Woo | Korea Atom Energy Res Inst, Daejeo 34057, South Korea; Chungnam Natl Univ, Dept Environm Engn, Daejeon 34134, South Korea; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu 41566, South Korea; KAIST Res Anal Ctr, Daejeon 34141, South Korea | ; Lee, Byeonggwan/HPD-2363-2023; Kim, Ga-yeong/HPE-4623-2023 | 57765349600; 57766427400; 57201269846; 55240130900; 58701618800; 56227488100; 57213033278; 14420116600; 56175751900; 55128039500 | hyunwookang@kaeri.re.kr; | JOURNAL OF NON-CRYSTALLINE SOLIDS | J NON-CRYST SOLIDS | 0022-3093 | 1873-4812 | 624 | SCIE | MATERIALS SCIENCE, CERAMICS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 3.5 | 16.7 | 0.99 | 2025-05-07 | 3 | 3 | Iodine immobilization; Radioactive iodine; Silver tellurite glass; Silver tungstate glass; Leaching property; Vitrification | XPS; SPECTRA; VITRIFICATION; SPECTROSCOPY; RADIOIODINE | Iodine immobilization; Leaching property; Radioactive iodine; Silver tellurite glass; Silver tungstate glass; Vitrification | Fission products; Fluorescence; Leaching; Nuclear fuels; Nuclear power plants; Radioactive wastes; Radioactivity; Silver oxides; Tellurium compounds; Tungsten compounds; X ray photoelectron spectroscopy; X ray powder diffraction; Glass matrices; Half lives; Iodine immobilizations; Leaching property; matrix; Property; Radioactive iodine; Silver tellurite glass; Silver tungstate glass; Tellurite glass; Glass | English | 2024 | 2024-01-15 | 10.1016/j.jnoncrysol.2023.122728 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Synthesis and characterization of eco-friendly, stable green-emitting Tb 3+-doped borosilicate glasses using waste silica gel | We present the results of an investigation that aimed to optimize the conversion of silica degradation from silica gel into glasses in hopes of reducing the amount of harmful chemical waste that is released into the environment. Glass samples were created by moderate- temperature melting process at 1200 degrees C, with the system combination of (69-x)B 2 O 3 - 18Li 2 O - 12BaO - xRSGW-1.0Tb 2 O 3 , where x = 0, 10, 20, 30, 40, 50 and 60 mol%, and RSGW stands for recovered silica gel waste. The chemical recycled silica gel waste was characterized using x-ray fluorescence (XRF) to determine its chemical composition. The recovered silica gel waste (RSGW) was employed in the manufacturing of glass in the role of a network former due to the considerable amount of SiO 2 that it contains. The optimal concentration of RSGW in the glass matrix is 30 mol% to achieve the highest excitation and emission intensities in photoluminescence and X-ray luminescence. The spectroscopic characteristics of borosilicate glass doped with Tb 3+ were investigated to show the influence of rare-earth ion additives on the composition, luminescence, and color of the materials. Green emissions of Tb 3+ (544 nm, 5 D 4 -> 7 F 5 ) was seen in Tb-doped glass when excited at 223 nm, 377 nm (under UV excitation). The color coordinates of the International Commission on Illumination chromaticity show the same shade of green color under different Tb 3+ concentrations (under 377 nm). The results of radioluminescence support the trend observed in the emission spectra. The concentration quenching of Tb 2 O 3 in (40-y)B 2 O 3 - 18Li 2 O - 12BaO - 30RSGW-yTb 2 O 3 glass is y = 1.0 mol% and suitable for use in light -emitting optoelectronic devices that emit the color green. | Rittisut, W.; Manyum, P.; Wantana, N.; Ruangtaweep, Y.; Rujirawat, S.; Kamonsuangkasem, K.; Yimnirun, R.; Prasatkhetragarn, A.; Kothan, S.; Kim, H.

| ○ | ○ | Article | Temperature Controlled Decay and Pendulum Dynamics of Green Fluorescent Protein (GFP) Chromophore | The excited-state dynamics of the GFP chromophore, HBDI- (anionic p-hydroxybenzylidene-2,3-dimethylimidazolinone), were investigated through a combination of theoretical nonadiabatic molecular dynamics (NAMD) simulations and femtosecond transient absorption spectroscopy (fs-TA). The NAMD simulations revealed that the primary dynamics in excited states involve the formation of a P-twisted intermediate (S1min,P ), which undergoes pendulum-like oscillations with respect to phi = 90 degrees. This motion serves as a reservoir for the excited-state population and the primary source of fluorescence. Rather than a direct channel from the major S1min,P , a coordinated pathway of S1min,P -> S1min -> S1min,I -> S0 is responsible for the decay to the ground state, emphasizing the importance of planar intermediate (S1min ) formation. The experimental fs-TA spectra confirmed these dynamics, revealing three distinct time scales (340-470 fs, 1.4 ps, and 8.3 ps), corresponding to the formation of S1min,P and its decay governed by the coordinated pathway. At low temperatures, the coordinated decay pathway is suppressed, leading to prolonged fluorescence lifetimes, consistent with low-temperature experimental results. This study presents a new model for the excited-state dynamics of GFP chromophore, suggesting that pendulum motion and the coordinated decay pathway play a crucial role in regulating fluorescence intensity. | Park, Woojin; Oh, Juwon; Kim, Jinseok; Lee, Seunghoon; Kim, Ji Heon; Huix-Rotllant, Miquel; Kim, Dongho; Choi, Cheol Ho | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Soonchunhyang Univ, Dept Chem, Asan 31538, South Korea; Yonsei Univ, Spect Lab Funct Mu Elect Syst, Seoul 03722, South Korea; Yonsei Univ, Dept Chem, Seoul 03722, South Korea; Seoul Natl Univ, Dept Chem, Seoul 151747, South Korea; Aix Marseille Univ, CNRS, ICR, F-13397 Marseille, France | Huix-Rotllant, Miquel/J-3291-2016; Lee, Seunghoon/AAB-4846-2021; , dongho/KIK-0073-2024 | 57223952329; 55812113000; 57194942520; 57194591254; 59089862800; 25634188900; 58476170300; 7402958948 | dongho@yonsei.ac.kr;cchoi@knu.ac.kr; | JOURNAL OF PHYSICAL CHEMISTRY LETTERS | J PHYS CHEM LETT | 1948-7185 | 15 | 46 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, ATOMIC, MOLECULAR & CHEMICAL | 2024 | 4.6 | 16.7 | 0.37 | 2025-05-07 | 3 | 3 | EXCITED-STATE DYNAMICS; RELAXATION; ALGORITHM; ORIGIN; CASPT2 | Green Fluorescent Proteins; Molecular Dynamics Simulation; Spectrometry, Fluorescence; Temperature; Decay (organic); Terahertz spectroscopy; Transient absorption spectroscopy; green fluorescent protein; Dynamics in excited state; Dynamics simulation; Excited-state dynamics; Excited-states; Femtosecond transient absorption spectroscopy; Green fluorescent protein; Hydroxybenzylidene; Lows-temperatures; Nonadiabatic molecular dynamics; State population; chemistry; molecular dynamics; spectrofluorometry; temperature; Pendulums | English | 2024 | 2024-11-08 | 10.1021/acs.jpclett.4c02761 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | The difference between service robots and human staff in the extended TPB model in airports | This study examined how to form behavioural intentions in regards to using the extended Theory of Planned Behaviour (TPB) model. This study more specifically proposed the effect of the overall service quality on attitude. In addition, it was hypothesized that attitude, subjective norm and perceived behavioural control have a positive influence on intention to use. Lastly, this study investigated the moderating role of the employee type, which included robots and humans, in the proposed model. The study collected data from 320 travellers who received services from only service robots and from 316 travellers who received services only from human staff at Incheon Airport in South Korea. The data analysis indicated that the overall service quality has a positive influence on attitude. In addition, it was discovered that intentions to use is positively affected by attitude, subjective norm and the perceived behavioural control. Finally, the type of employee moderated the relationship between the overall service quality and attitude. | Hwang, Jinsoo; Joo, Kyu-Hyeon; Kim, Heather (Markham); Lee, Jenni Soo-Hee | Sejong Univ, Coll Hospitality & Tourism Management, Seoul, South Korea; Kyungpook Natl Univ, Dept Tourism, Sangju, South Korea | Hwang, Jinsoo/AAG-9531-2019 | 36052898700; 57487338300; 57298775500; 57201076247 | jdmr0503@gmail.com; | CURRENT ISSUES IN TOURISM | CURR ISSUES TOUR | 1368-3500 | 1747-7603 | 27 | 12 | SSCI | HOSPITALITY, LEISURE, SPORT & TOURISM | 2024 | 4.6 | 16.9 | 3.89 | 2025-04-16 | 13 | 13 | Service robots; extended Theory of Planned Behavior (TPB); airline industry; behavioural intentions | PLANNED BEHAVIOR; QUALITY; ATTITUDE; TECHNOLOGY; INTENTION; NORM; SATISFACTION; ADOPTION; DRIVERS; TRAVEL | airline industry; behavioural intentions; extended Theory of Planned Behavior (TPB); Service robots | Incheon [South Korea]; South Korea; airline industry; airport; perception; public attitude; robotics; service quality | English | 2024 | 2024-06-17 | 10.1080/13683500.2023.2215975 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Clinical Role of Upfront F-18 FDG PET/CT in Determining Biopsy Sites for Lung Cancer Diagnosis | Purpose: This study aimed to investigate the impact of FDG PET/CT timing for biopsy site selection in patients with stage IV lung cancer regarding complications and diagnostic yield. Methods: This retrospective analysis was performed on 1297 patients (924 men and 373 women with a mean age of 71.4 +/- 10.2 years) who underwent percutaneous needle biopsy (PNB) for stage IV lung cancer diagnosis in two hospitals. Data collected included the patient's characteristics, order date of the biopsy and PET/CT exams, biopsy target site (lung or non-lung), guidance modality, complications, sample adequacy, and diagnostic success. Based on the order date of the PNB and PET/CT exams, patients were categorized into upfront and delayed PET/CT groups. Results: PNB for non-lung targets resulted in significantly lower rates of minor (8.1% vs. 16.2%), major (0.2% vs. 3.4%), and overall complications (8.3% vs. 19.6%) compared to PNB for lung targets (p < 0.001 for all types of complications). Compared to the delayed PET/CT group, the upfront PET/CT group exhibited a lower probability of lung target selection of PNB (53.9% vs. 67.1%, p < 0.001), including a reduced incidence of major complications (1.0% vs. 2.9%, p = 0.031). Moreover, there was no significant difference in the occurrence of minor and total complications between the two groups. Upfront PET/CT and delayed PET/CT groups showed no significant difference regarding sample adequacy and diagnostic success. Conclusions: Upfront PET/CT may have an impact on the selection of the biopsy site for patients with advanced lung cancer, which could result in a lower rate of major complications with no change in the diagnostic yield. Upfront PET/CT demonstrates potential clinical implications for enhancing the safety of lung cancer diagnosis in clinical practice. | Park, Byunggeon; Lim, Jae-Kwang; Shin, Kyung Min; Hong, Jihoon; Cha, Jung Guen; Cho, Seung Hyun; Park, Seo Young; Ryeom, Hun Kyu; Kim, See Hyung; Seo, An Na; Cha, Seung-Ick; Lee, Jaehee; Lee, Hoseok; Park, Jongmin | Kyungpook Natl Univ, Sch Med, Dept Radiol, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Pathol, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu 41944, South Korea; Semyung Radiol Clin, Dept Radiol, Gumi 39254, Gyeongsangbuk D, South Korea | Kim, Sang-Hyun/J-5402-2012; Lee, Yoojin/AAB-9799-2022; Lee, Jaehee/S-1697-2018; Seo, An Na/F-6440-2015 | 57211532915; 55515341400; 7402410737; 57215858314; 57206855971; 55686242700; 57210379391; 6505864513; 57216511386; 55804153700; 35227126400; 13805476000; 57200653487; 57216463879 | jmmpark@knu.ac.kr; | DIAGNOSTICS | DIAGNOSTICS | 2075-4418 | 14 | 2 | SCIE | MEDICINE, GENERAL & INTERNAL | 2024 | 3.3 | 17.0 | 1.62 | 2025-04-16 | 2 | 2 | lung cancer; biopsy; positron emission tomography computed tomography | TRANSTHORACIC NEEDLE-BIOPSY; GUIDED PERCUTANEOUS BIOPSY; PERIPHERAL LUNG; CT; LESIONS; SAFETY; PERFORMANCE; ACCURACY; YIELD; US | biopsy; lung cancer; positron emission tomography computed tomography | fluorodeoxyglucose f 18; aged; Article; bleeding; cohort analysis; diagnostic value; female; hematoma; hematothorax; hemoptysis; human; human tissue; large cell carcinoma; lung adenocarcinoma; lung cancer; major clinical study; male; multidetector computed tomography; needle biopsy; non small cell lung cancer; pneumothorax; positron emission tomography-computed tomography; retrospective study; safety; sarcomatoid carcinoma; small cell lung cancer; squamous cell lung carcinoma | English | 2024 | 2024-01 | 10.3390/diagnostics14020153 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Exploring Voice Acoustic Features Associated with Cognitive Status in Korean Speakers: A Preliminary Machine Learning Study | Objective: To develop a non-invasive cognitive impairment detection system using speech data analysis, addressing the growing global dementia crisis and enabling accessible early screening through daily health monitoring. Methods: Speech data from 223 Korean patients were collected across eight tasks. Patients were classified based on Korean Mini-Mental State Examination scores. Four machine learning models were tested for three binary classification tasks. Voice acoustic features were extracted and analyzed. Results: The Deep Neural Network model performed best in two classification tasks, with Precision-Recall Area Under the Curve scores of 0.737 for severe vs. no impairment and 0.726 for mild vs. no impairment, while Random Forest achieved 0.715 for severe + mild vs. no impairment. Several acoustic features emerged as potentially important indicators, with DDA shimmer from the /i/ task and stdevF0 from the /puh-tuh-kuh/ task showing consistent patterns across classification tasks. Conclusions: This preliminary study suggests that certain acoustic features may be associated with cognitive status, though demographic factors significantly influence these relationships. Further research with demographically matched populations is needed to validate these findings. | Lee, Jiho; Kim, Nayeon; Ha, Ji-Wan; Kang, Kyunghun; Park, Eunhee; Yoon, Janghyeok; Park, Ki-Su | Neopons Inc, Daegu 41260, South Korea; Daegu Univ, Dept Speech Language Pathol, Gyongsan 38453, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurol, Daegu 41404, South Korea; Kyungpook Natl Univ, Sch Med, Dept Rehabil Med, Daegu 41404, South Korea; Konkuk Univ, Dept Ind Engn, Seoul 05029, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurosurg, Daegu 41404, South Korea | 57221320001; 57072206000; 57072470300; 55365592200; 56107216400; 36451492000; 55932363100 | jiholee255@neopons.com;nancy@neopons.com;jw-ha@daegu.ac.kr;kangkh@knu.ac.kr;ehmdpark@naver.com;janghyoon@konkuk.ac.kr;kspark@neopons.com; | DIAGNOSTICS | DIAGNOSTICS | 2075-4418 | 14 | 24 | SCIE | MEDICINE, GENERAL & INTERNAL | 2024 | 3.3 | 17.0 | 0 | 2025-05-07 | 0 | 0 | cognitive impairment; pre-screening; K-MMSE; speech features; speech tasks; deep learning | ALZHEIMERS-DISEASE; DEMENTIA; SPEECH; IMPAIRMENT; JITTER; AGE; DIADOCHOKINESIS; CLASSIFICATION; BIOMARKERS; ALGORITHM | cognitive impairment; deep learning; K-MMSE; pre-screening; speech features; speech tasks | acoustics; adult; aged; Article; binary classification; cognition; cognitive defect; controlled study; data analysis; deep neural network; dementia; disease severity; female; human; Korean (people); machine learning; major clinical study; male; mild cognitive impairment; Mini Mental State Examination; monitoring; non invasive procedure; random forest; speech; task performance | English | 2024 | 2024-12 | 10.3390/diagnostics14242837 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Human Papillomavirus Infection of the Oropharyngeal and Laryngeal Squamous Papilloma: Disparities in Prevalence and Characteristics | Human papillomavirus (HPV) infection has emerged as an etiologic factor of squamous papilloma (SP). The oropharynx and larynx are common sites of SP, but studies on the prevalence of HPV infection in these sites are lacking. This study aimed to evaluate and compare the prevalence and characteristics of HPV infection in oropharyngeal SP (OPSP) and laryngeal SP (LSP). HPV detection and genotyping data of patients with pathologically confirmed OPSP and LSP were retrospectively analyzed. A total of 119 patients were enrolled, consisting of 93 patients with OPSP and 26 patients with LSP. Of those patients, 13 patients with OPSP and 14 patients with LSP were positive for HPV infection, accounting for a prevalence of 14.0% and 53.8%, respectively (p < 0.001). The most prevalent genotype was HPV16 in OPSP and HPV6 in LSP. Over two-thirds (69.2%) of HPV(+)-OPSP infections were high-risk types compared with 14.3% of HPV(+)-LSP infections (p = 0.004). The prevalence of HPV infection in patients with OPSP and LSP demonstrated no differences in terms of age, sex, and smoking status. These results could provide a better understanding of HPV infection in OPSP and LSP and serve as a background for the epidemiology of HPV-related tumorigenesis of the oropharynx and larynx. | Kwak, Jihye; Ahn, Dongbin; Kim, Mee-seon | Kyungpook Natl Univ, Sch Med, Dept Otolaryngol Head & Neck Surg, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Pathol, Daegu 41944, South Korea | 57393330600; 44761055400; 56123006700 | laugh112@naver.com;godlikeu@naver.com;kimm23@naver.com; | DIAGNOSTICS | DIAGNOSTICS | 2075-4418 | 14 | 11 | SCIE | MEDICINE, GENERAL & INTERNAL | 2024 | 3.3 | 17.0 | 0.73 | 2025-05-07 | 1 | 1 | squamous papilloma; human papillomavirus; oropharynx; larynx; prevalence; genotype | UNITED-STATES; HPV INFECTION; NECK; HEAD; CANCER | genotype; human papillomavirus; larynx; oropharynx; prevalence; squamous papilloma | adult; Article; cohort analysis; controlled study; current smoker; dysplasia; ex-smoker; female; genotype; genotyping; histopathology; human; Human papillomavirus type 11; Human papillomavirus type 16; Human papillomavirus type 6; human tissue; immunohistochemistry; laryngeal squamous papilloma; major clinical study; male; middle aged; never smoker; oropharyngeal squamous papilloma; papilloma; papillomavirus infection; people by smoking status; prevalence; retrospective study | English | 2024 | 2024-06 | 10.3390/diagnostics14111163 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Intraoperative Facial Nerve Monitoring during Parotidectomy: The Current Practices and Patterns of the Korean Society of Head and Neck Surgery (KSHNS) | Objectives: This study aimed to evaluate the current practices and trends of intraoperative facial nerve (FN) monitoring (IOFNM) during parotidectomy. Methods: A questionnaire containing 33 questions collecting information on the usage, indications, settings, techniques, loss of signal (LOS) management, anesthesiologist cooperation, and perception of usefulness of IOFNM was distributed among 348 members of the Korean Society of Head and Neck Surgery (KSHNS) via a dedicated website. Results: The response rate was approximately 25.6%, and 97% of the respondents reported using IOFNM selectively or routinely during parotidectomy. IOFNM usage decreased as the surgeon's level of experience increased (p = 0.089), from 100% in those with less than 5 years of experience to 75% in those with 20 or more years. Approximately 95% of respondents reported that the initial event threshold for electromyography activity used was 50-149 mu V. Moreover, 52.4% of respondents performed neural mapping of the FN before visual identification. Initial management of LOS in visually intact FNs included checking the IOFNM system (75.3%), confirmation of muscle relaxant dosage (75.3%), and facial twitch identification (58.8%). Further management included proceeding with surgery regardless of persistent LOS (81.2%) and steroid administration sometimes or all of the time (72.9%). Overall, 98.8% of respondents found IOFNM beneficial for safe execution of parotidectomy. Conclusions: The majority of KSHNS surgeons used IOFNM during parotidectomy, although the clinical implementation of the procedure and LOS management varied between practitioners. This could be attributed to the lack of standardized protocols for IOFNM, emphasizing the need for the development of evidence-based consensus guidelines for all institutions. | Ahn, Dongbin; Kwak, Ji Hye; Kim, Geun-Jeon; Kim, Heejin; Lee, Dong Won; Cho, Kwang Jae | Kyungpook Natl Univ, Sch Med, Dept Otolaryngol Head & Neck Surg, Daegu 41566, South Korea; Catholic Univ Korea, Coll Med, Dept Otolaryngol Head & Neck Surg, Seoul 06591, South Korea; Hallym Univ, Dept Otolaryngol Head & Neck Surg, Sacred Heart Hosp, Anyang 14068, South Korea; Catholic Univ Daegu, Sch Med, Dept Otolaryngol Head & Neck Surg, Daegu 42472, South Korea | Lee, Dongwon/IAU-6865-2023 | 44761055400; 57393330600; 56532862800; 56984360400; 57202974901; 34867747900 | godlikeu@naver.com;laugh112@naver.com;emelenciana@naver.com;heejin5020@daum.net;ldw3878@hanmail.net;entckj@catholic.ac.kr; | DIAGNOSTICS | DIAGNOSTICS | 2075-4418 | 14 | 20 | SCIE | MEDICINE, GENERAL & INTERNAL | 2024 | 3.3 | 17.0 | 0 | 2025-05-07 | 0 | 0 | parotid; facial nerve; palsy; electromyography; monitoring | THYROID-SURGERY; STEROIDS; TUMORS | electromyography; facial nerve; monitoring; palsy; parotid | muscle relaxant agent; steroid; adult; anesthesiologist; Article; clinical practice; electromyography; facial nerve; female; head and neck surgery; human; incidence; intraoperative period; Korea; major clinical study; male; medical society; muscle twitch; paralysis; parotidectomy; practice guideline; questionnaire; surgical technique; treatment indication; trend study | English | 2024 | 2024-10 | 10.3390/diagnostics14202277 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Opportunistic Screening for Acute Vertebral Fractures on a Routine Abdominal or Chest Computed Tomography Scans Using an Automated Deep Learning Model | Objectives: To develop an opportunistic screening model based on a deep learning algorithm to detect recent vertebral fractures in abdominal or chest CTs. Materials and Methods: A total of 1309 coronal reformatted images (504 with a recent fracture from 119 patients, and 805 without fracture from 115 patients), from torso CTs, performed from September 2018 to April 2022, on patients who also had a spine MRI within two months, were included. Two readers participated in image selection and manually labeled the fractured segment on each selected image with Neuro-T (version 2.3.3; Neurocle Inc.) software. We split the images randomly into the training and internal test set (labeled: unlabeled = 480:700) and the secondary interval validation set (24:105). For the observer study, three radiologists reviewed the CT images in the external test set with and without deep learning assistance and scored the likelihood of an acute fracture in each image independently. Results: For the training and internal test sets, the AI achieved a 99.86% test accuracy, 91.22% precision, and 89.18% F1 score for detection of recent fracture. Then, in the secondary internal validation set, it achieved 99.90%, 74.93%, and 78.30%, respectively. In the observer study, with the assistance of the deep learning algorithm, a significant improvement was observed in the radiology resident's accuracy, from 92.79% to 98.2% (p = 0.04). Conclusion: The model showed a high level of accuracy in the test set and also the internal validation set. If this algorithm is applied opportunistically to daily torso CT evaluation, it will be helpful for the early detection of fractures that require treatment. | Kim, Ye Rin; Yoon, Yu Sung; Cha, Jang Gyu | Soonchunhyang Univ, Bucheon Hosp, Coll Med, Dept Radiol, Bucheon 14584, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Radiol, Daegu 41944, South Korea | Cha, Jang/U-3216-2019 | 57781335000; 57414392900; 16027832300 | zick1853@gmail.com; | DIAGNOSTICS | DIAGNOSTICS | 2075-4418 | 14 | 7 | SCIE | MEDICINE, GENERAL & INTERNAL | 2024 | 3.3 | 17.0 | 0 | 2025-05-07 | 1 | 2 | deep learning; artificial intelligence; vertebral compression fracture; spine; computed tomography | BODY COMPRESSION FRACTURES; CT; UNDERDIAGNOSIS | artificial intelligence; computed tomography; deep learning; spine; vertebral compression fracture | abdominal radiography; adult; Article; artificial intelligence; clinical practice; cohort analysis; compression fracture; controlled study; deep learning; emergency medicine; false positive result; female; human; major clinical study; male; middle aged; nuclear magnetic resonance imaging; osteophyte; radiologist; retrospective study; spine surgery; thorax radiography; vertebra body; x-ray computed tomography | English | 2024 | 2024-04 | 10.3390/diagnostics14070781 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Visceral Obesity and Its Association with Severe Coronary Artery Calcification in Patients with Metabolic Dysfunction-Associated Steatotic Liver Disease | Background/Objectives: The role of body composition parameters in patients with metabolic dysfunction-associated steatotic liver disease (MASLD) with presence and severity of coronary artery calcification (CAC) is still not fully elucidated. We aimed to evaluate the impact of computed tomography (CT)-based body composition parameters in patients with MASLD with CAC severity. Methods: In this multicenter study, 1870 individuals underwent cardiac CT for the detection of CAC as well as ultrasonography for the diagnosis of hepatic steatosis. The presence of CAC was defined by a CAC score threshold of >0, while severe CAC was defined by a threshold of >300. Using the abdominal cross-sectional CT images at the L3 vertebra level, we analyzed the skeletal muscle index, visceral to subcutaneous adipose tissue ratio, and muscle density using the Hounsfield unit. Results: Of 648 patients with MASLD, the proportions of presence of CAC and severe CAC were 45.2% and 9.9%, respectively. Visceral obesity was not associated with the presence of CAC after adjustment for age, sex, smoking, statin therapy, type 2 diabetes, and advanced fibrosis (adjusted odds ratio (aOR), 1.38; 95% confidence interval (CI), 0.86-2.23; p = 0.180). However, visceral obesity was independently associated with severe CAC after adjustment for several metabolic risk factors (aOR, 3.54; 95% CI, 1.25-14.90; p = 0.039), and adjustment for atherosclerotic cardiovascular disease risk scores (aOR, 3.74; 95% CI, 1.31-15.79; p = 0.032). Conclusions: Visceral obesity may serve as a novel prognostic CT-based radiological biomarker for patients with MASLD with severe CAC. | Kang, Min Kyu; Song, Jeung Eun; Kweon, Young Oh; Tak, Won Young; Park, Soo Young; Lee, Yu Rim; Park, Jung Gil | Yeungnam Univ, Coll Med, Dept Internal Med, Daegu 42415, South Korea; Daegu Catholic Univ, Sch Med, Dept Internal Med, Daegu 42472, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Internal Med, Daegu 41994, South Korea | ; Park, Jung/AAK-5167-2020; Kang, Min/U-8050-2018 | 59142854300; 57189097150; 7004694832; 7004074582; 57191674344; 57194094753; 57216816399 | kmggood111@naver.com;ssong3004@naver.com;yokweon@knu.ac.kr;wytak@knu.ac.kr;psyoung0419@gmail.com;deblue00@naver.com;gsnrs@naver.com; | DIAGNOSTICS | DIAGNOSTICS | 2075-4418 | 14 | 20 | SCIE | MEDICINE, GENERAL & INTERNAL | 2024 | 3.3 | 17.0 | 0 | 2025-05-07 | 0 | 1 | atherosclerotic cardiovascular disease; coronary artery calcification; metabolic dysfunction-associated steatotic liver disease; visceral obesity | DELPHI CONSENSUS STATEMENT; FATTY LIVER; ADIPOSE-TISSUE; CARDIOVASCULAR-DISEASE; RISK-FACTORS | atherosclerotic cardiovascular disease; coronary artery calcification; metabolic dysfunction-associated steatotic liver disease; visceral obesity | biological marker; hemoglobin A1c; hydroxymethylglutaryl coenzyme A reductase inhibitor; adult; aged; Article; body composition; computer assisted tomography; controlled study; coronary artery calcification; coronary atherosclerosis; cross-sectional study; current smoker; disease association; disease risk assessment; disease severity; echography; female; human; liver fibrosis; major clinical study; male; metabolic fatty liver; multicenter study; multicenter study (topic); obesity; prevalence; retrospective study; risk factor; sarcopenia; skeletal muscle; subcutaneous fat; third lumbar vertebra | English | 2024 | 2024-10 | 10.3390/diagnostics14202305 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | A deep clustering framework for load pattern segmentation | In recent years, the widespread use of smart meters in power networks has generated a wealth of data from electricity customers. However, much of this real-world smart meter dataset lacks labeled data, posing a significant challenge that can be addressed by clustering. Traditional clustering methods often struggle in high-dimensional spaces, leading to less accurate results and increased computational demands. In response to these challenges, this research introduces a framework that utilizes a deep-learning-based clustering approach to address the issue of accurate customer clustering based on usage patterns in unlabeled data. Using an autoencoder, our approach integrates dimensionality reduction and clustering into an end-to-end unsupervised learning framework. Our algorithm significantly improves load profiling by tackling challenges related to nonlinear decision boundaries at the autoencoder bottleneck. Unlike traditional approaches, we propose separating the optimization of reconstruction and cluster loss, bridging the gap between clustering quality and reconstruction efficiency. We rigorously analyze the performance of our approach by comparing classical and state-of-the-art algorithms using two real-world smart meter data. We provide a comprehensive comparative analysis of our method against five common dimension reduction techniques used in high-dimensional clustering. The experimental analysis concludes that the proposed algorithm significantly enhances load profiling more than others, as confirmed through detailed load curve analysis and clustering validity indexes. This comprehensive assessment highlights the effectiveness and versatility of our proposed methodology when compared to others. Moreover, this research advances load profiling in smart grid analytics, providing practical insights for utilities and stakeholders looking to optimize power network operations. | Kumar, Abhimanyu; Mallipeddi, Rammohan | Kyungpook Natl Univ, Dept Artificial Intelligence, DaehakRo, Daegu 41566, South Korea | Mallipeddi, Rammohan/AAL-5306-2020 | 57845674200; 25639919900 | abbhikummar@gmail.com;mallipeddi.ram@gmail.com; | SUSTAINABLE ENERGY GRIDS & NETWORKS | SUSTAIN ENERGY GRIDS | 2352-4677 | 38 | SCIE | ENERGY & FUELS;ENGINEERING, ELECTRICAL & ELECTRONIC | 2024 | 5.6 | 17.1 | 1.19 | 2025-05-07 | 5 | 6 | Smart grid; Deep clustering; Load pattern; Dimensionality reduction; Autoencoder | CLASSIFICATION; BUILDINGS | Autoencoder; Deep clustering; Dimensionality reduction; Load pattern; Smart grid | Cluster analysis; Clustering algorithms; Deep learning; Electric loads; Electric network analysis; Learning systems; Power quality; Reduction; Smart power grids; Auto encoders; Clusterings; Deep clustering; Dimensionality reduction; Electricity customers; Load patterns; Load profiling; Power networks; Real-world; Smart grid; Smart meters | English | 2024 | 2024-06 | 10.1016/j.segan.2024.101319 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Development of a high-performance cymbal vector hydrophone | Detecting the direction of sound wave propagation using conventional acoustic hydrophones can be challenging, as they are omnidirectional and only measure the magnitude of sound pressure. However, vector hydrophones offer a solution to this problem, which enables the determination of both magnitude and direction of sound waves. In this study, we propose a novel structure for a vector hydrophone that consists of two cymbal transducers attached to a hollow cylindrical frame, positioned facing each other. Initially, we analyze the received voltage sensitivity of the two cymbal transducers and evaluate the suitability of the structure as a vector hydrophone by implementing a dipole mode beam pattern. Furthermore, we investigate the impact of structural parameters on the performance of the vector hydrophone. Based on these findings, we derive the optimal structure for the vector hydrophone, maximizing its sensitivity. Finally, we validate the design by manufacturing a prototype of the cymbal vector hydrophones and comparing their measured performance with the calculated values. | Kim, Donghyun; Roh, Yongrae | Kyungpook Natl Univ, 80 Daehakro, Daegu 41566, South Korea | 58950709000; 7102361870 | yryong@knu.ac.kr; | SENSORS AND ACTUATORS A-PHYSICAL | SENSOR ACTUAT A-PHYS | 0924-4247 | 1873-3069 | 365 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;INSTRUMENTS & INSTRUMENTATION | 2024 | 4.9 | 17.1 | 2.06 | 2025-04-16 | 6 | 6 | Cymbal transducer; Vector hydrophone; Receiving voltage sensitivity (RVS); Dipole mode beam pattern | SENSOR; TRANSDUCER | Cymbal transducer; Dipole mode beam pattern; Receiving voltage sensitivity (RVS); Vector hydrophone | Acoustic wave propagation; Structural optimization; Vectors; Beam pattern; Cymbal transducer; Dipole mode; Dipole mode beam pattern; Performance; Receiving voltage sensitivity; Sound pressures; Sound wave propagation; Vector hydrophones; Voltage sensitivity; Hydrophones | English | 2024 | 2024-01-01 | 10.1016/j.sna.2023.114928 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
