| ○ | ○ | Article | Skin pore imaging using spectral-domain optical coherence tomography: a case report | Sebum is an important component of the skin that has attracted attention in many fields, including dermatology and cosmetics. Pore expansion due to sebum on the skin can lead to various problems. Therefore, it is necessary to analyze the morphological characteristics of sebum. In this study, we used optical coherence tomography (OCT) to evaluate facial sebum areas. We obtained the OCT maximum amplitude projection (MAP) image and a cross-sectional image of skin pores in the facial area. Subsequently, we detected the sebum in skin pores using the detection algorithm of the ImageJ software to quantitatively determine the size of randomly selected pores in the proposed MAP images. Additionally, the pore size was analyzed by acquiring images before and after facial sebum extraction. According to our research, facial sebum can be morphologically described using the OCT system. Since OCT imaging enables specific analysis of skin parameters, including pores and sebum, skin analysis employing OCT could be an effective method for further research. | Kim, Hyunmo; Kang, Dongwan; Seong, Daewoon; Abu Saleah, Sm; Luna, Jannat Amrin; Kim, Yoonseok; Kim, Hayoung; Han, Sangyeob; Jeon, Mansik; Kim, Jeehyun | Kyungpook Natl Univ, Coll IT Engn, Sch Elect & Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Inst Biomed Engn, Sch Med, Daegu 41566, South Korea | Kim, Jinhyun/AAK-3695-2020 | 58078407800; 58079924200; 57212512353; 57218499446; 58079161200; 57216828837; 57214326551; 57193695305; 24171094000; 7601373350 | msjeon@knu.ac.kr;jeehk@knu.ac.kr; | BIOMEDICAL ENGINEERING LETTERS | BIOMED ENG LETT | 2093-9868 | 2093-985X | 13 | 4 | SCIE | ENGINEERING, BIOMEDICAL | 2023 | 3.2 | 45.1 | 0.27 | 2025-06-25 | 2 | 2 | Facial skin pore; Spectral-domain optical coherence tomography (SD-OCT); Sebum extraction; Image processing; Cross-sectional image | SURFACE; SYSTEM; MICROSCOPY; TEXTURE; OCT | Cross-sectional image; Facial skin pore; Image processing; Sebum extraction; Spectral-domain optical coherence tomography (SD-OCT) | Coherent light; Extraction; Optical data processing; Pore size; Strain measurement; Cross sectional image; Facial skin; Facial skin pore; Images processing; Maximum amplitude; Projection image; Sebum extraction; Skin pores; Spectral domain optical coherence tomographies; Spectral-domain optical coherence tomography; A scan; amplitude modulation; Article; case report; detection algorithm; extraction; facial sebum extraction; fluorescence microscopy; human; image analysis; image processing; image quality; imaging; JAVA; maximum amplitude projection; measurement precision; optical resolution; parameters; pore size; quantitative analysis; sebum; skin analysis; skin examination; skin parameters; skin pore imaging; software; spectral domain optical coherence tomography; Optical tomography | English | 2023 | 2023-11 | 10.1007/s13534-023-00290-y | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Solar Array Drive Assembly Disturbance Modeling, Jitter Analysis and Validation Tests for Precision Space-Based Operations | Background Vibrations in space operations, induced by disturbance torque of solar array drive assembly (SADA), is one of the major setbacks, as these reduce performance precision of satellite. Purpose Aiming to simulate behavior of solar panel, this work provides an analytical modeling and analysis method to calculate the disruption response of SADA rotating flexible loading. Methodology The discussed SADA is 64 subdivisions bi-phase hybrid step drive with variably toothed rotor. Initially, vibration equation of step motor is obtained by linearization and simplification of electromagnetic torque. For precise ground testing, a measurement system comprising of piezoelectric test platform is designed to measure and validate no load SADA disturbance. Based on SADA dynamic equation and employing the force/moment analysis, disturbance torque produced by drive is approximated when it is operating rigid load. The results, validated through simulations to provide amplitude of coupled vibrations, imply that the suggested model for disturbance torque possesses the aptitude to demonstrate the vibrations generated by drive motor with high accuracy. Results and Conclusion Analytical and simulation studies, used to examine the effect of increasing the number of rotor teeth on the vibration behavior of subdivided SADA, show an increase in frequency and a decrease in amplitude of produced vibrations. All of the analysis approaches provide a foundation for analyzing SADA vibrations and their impact on actual solar arrays. | Sattar, Mariyam; Alzaid, Meshal; Junejo, Naveed Ur Rehman; Malik, Rizwan Ahmed; Tanveer, Muhammad; Latif, Muhammad | Inst Space Technol, Dept Mech Engn, Islamabad, Pakistan; Jouf Univ, Coll Sci, Phys Dept, POB 2014, Sakaka, Saudi Arabia; Univ Lahore, Lahore Campus, Lahore, Pakistan; Univ Engn & Technol, Fac Mech & Aeronaut Engn, Dept Met & Mat Engn, Taxila 47050, Pakistan; Kyungpook Natl Univ, Sch Mech Engn, Bio Expt Fluid Engn Lab, 80 Daehakro, Daegu 41566, South Korea; Inha Univ, Ctr Nanocellulose Future Composites, Dept Mech Engn, Michuhol Ku, 100 Inha Ro, Incheon 22212, South Korea | Malik, Rizwan Ahmed/O-1146-2016; Junejo, Naveed/ABD-7604-2020; Sattar, Mariyam/KCJ-9803-2024; Tanveer, MuhammadShahbaz/LUY-0421-2024; Alzaid, Meshal/AGK-6244-2022 | 57191824801; 57193761447; 57201306787; 35604043900; 23486949200; 58580759400 | mmalzaid@ju.edu.sa; | JOURNAL OF VIBRATION ENGINEERING & TECHNOLOGIES | J VIB ENG TECHNOL | 2523-3920 | 2523-3939 | 11 | 5 | SCIE | ENGINEERING, MECHANICAL;MECHANICS | 2023 | 2.1 | 45.1 | 0.5 | 2025-06-25 | 4 | 3 | Solar array drive assembly; Step motor; Disturbance torque; Rotor teeth; Subdivisions; Piezoelectric test platform; Electromagnetic torque | STEPPER MOTOR; DYNAMICS; SIMULATION; VIBRATION | Disturbance torque; Electromagnetic torque; Piezoelectric test platform; Rotor teeth; Solar array drive assembly; Step motor; Subdivisions | English | 2023 | 2023-07 | 10.1007/s42417-022-00688-5 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Discharge transitional care programme for older adults after hip fracture surgery: a quasi-experimental study | Background: Hip fractures require extended periods of recovery and rehabilitation, subjecting older adults to discontinuous care. Discharge transition is a critical point of heightened vulnerability for older adults. Aims: This study aimed to evaluate the effectiveness of a transitional care programme on the physical functions and quality of life (QOL) of older adults after hip fracture surgery. Methods: Seventy-five older adults were assessed from pre-discharge to 6 weeks after hip surgery, and their physical functions, including walking status and activities of daily living, were measured. The QOL was measured using the European Quality of life-5 Dimensions-5 Levels (EQ 5D 5L). Results: There was a significant strong effect of time (B = 10.565; 95% CI = 2.584-18.547; p = 0.009) on the EuroQol Visual Analog Scale (EQ-VAS) for the experimental group. However, there were no significant effects of time on physical functions and EQ-5D-5L scores. Conclusions: The discharge transitional care programme improved the EQ-VAS of older adults following hip fracture surgery 6 weeks post-surgery. However, there were no significant differences in physical functions and EQ-5D between the groups. | Ko, Youngji; Hwang, Jong-Moon; Baek, Seung-Hoon | Daegu Haany Univ, Dept Nursing, Room 201,12 Bldg, Gyongsan 38610, Gyeongsangbuk D, South Korea; Kyungpook Natl Univ Hosp, Dept Rehabil Med, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Orthoped Surg, Daegu, South Korea | Ko, YoungJi/ABD-6413-2020 | 57209233650; 56367634000; 56232924900 | yjko@dhu.ac.kr; | JOURNAL OF RESEARCH IN NURSING | J RES NURS | 1744-9871 | 1744-988X | 28 | 8 | ESCI | NURSING | 2023 | 1.6 | 45.3 | 0.31 | 2025-06-25 | 1 | 1 | hip fractures; older adults; patient discharge; quality of life; surgery; transitional care | INTERVENTIONS; QUALITY; LIFE | hip fractures; older adults; patient discharge; quality of life; surgery; transitional care | English | 2023 | 2023-12 | 10.1177/17449871231204499 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Impact of marginal defects on the accuracy of automated finish line detection in tooth preparation | Aim: The present study aimed to evaluate the accuracy of automated detection of preparation finish lines in teeth with defective margins. Materials and methods: An extracted first molar was prepared for a full veneer crown, and marginal defects were created and scanned (discontinuity of finish line: 0.5, 1.0, and 1.5 mm; additional line angle: connected, partially connected, and disconnected). Six virtual defect models were entered into CAD software and the preparation finish line was designated by 20 clinicians (CAD-experienced group: n = 10; CAD-inexperienced group: n = 10) using the automated finish line detection method. The accuracy of automatic detection was evaluated by calculating the 3D deviation of the registered finish line. The Kruskal-Wallis and Mann -Whitney U tests were used for between-group comparisons (alpha = 0.05). Results: The deviation values of the registered finish lines were significantly different according to conditions with different amounts of finish line discontinuity (P < 0.001). There was no statistical difference in the deviation of the registered finish line between models with additional line angles around the margin. Moreover, no statistical difference was found in the results between CAD-experienced and CAD -inexperienced operators. Conclusions: The accuracy of automated finish line detection for tooth preparation can differ when the finish line is discontinuous. The presence of an additional line angle around the preparation margin and prior experience in dental CAD software do not affect the accuracy of automated finish line detection. | Park, Jun Hyub; Lee, Du-Hyeong | Kyungpook Natl Univ, Dept Prosthodont, Sch Dent, Taegu, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Prosthodont, Daegu, South Korea; Kyungpook Natl Univ, Inst Translat Res Dent, Daegu, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Prosthodont, 2175 Dalgubeol Daero, Daegu, South Korea | 58742290500; 35770948000 | deweylee@knu.ac.kr; | INTERNATIONAL JOURNAL OF COMPUTERIZED DENTISTRY | INT J COMPUT DENT | 1463-4201 | 26 | 4 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2023 | 1.8 | 45.3 | 0 | 2025-06-25 | 0 | 0 | tooth preparation; marginal defect; computer aided design; finish line; automated detection; computer algorithm | IN-VITRO; CROWNS; FIT; FUTURE | automated detection; computer algorithm; computer-aided design; finish line; marginal defect; tooth preparation | Computer-Aided Design; Crowns; Dental Marginal Adaptation; Dental Prosthesis Design; Humans; Tooth Preparation; Tooth Preparation, Prosthodontic; Zirconium; zirconium; computer aided design; dental marginal adaptation; dental surgery; human; procedures; prosthesis design | English | 2023 | 2023 | 10.3290/j.ijcd.b3840393 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Secondary healing property using Neoveil®, a polyglycolic acid bioabsorbable sheet on the oral mucosal defects | Neoveil (R) is a wound surface-covering agent composed of polyglycolic acid(PGA) effective for secondary heal-ing. This study evaluated the secondary healing property of oral cavity mucosal defects using the PGA sheet. Thirty-four patients who underwent surgical excision of oral benign and malignant lesions, precancerous lesions, and tumors were evaluated. The PGA sheet was placed over the open wound to aid secondary heal-ing. The defects were reviewed post-operatively for secondary healing, contracture, and secondary defor-mity. Male to female ratio was 20:14, and the mean age was 63.5 years. In all cases, the oral mucosal defect was present after the wide excision of the mucosal lesion. The PGA sheet was used as a surface covering agent which was found to be effective in secondary healing of the wound. Any side effects and adverse reac-tions which were caused by the PGA sheet was not evident. It can be used to avoid skin graft or free flap reconstruction or deformity from the direct closure in moderate size oral mucosal defect.(c) 2022 Published by Elsevier Masson SAS. | Udayakumar, Santhiya Iswarya Vinothini; Kwon, Dohyun; Kwon, Tae-Geon; Paeng, Jun-Young | Sungkyunkwan Univ, Samsung Med Ctr, Dept Oral & Maxillofacial Surg, Sch Med, 50 Irwon dong, Seoul, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Oral & Maxillofacial Surg, Daegu, South Korea | Udayakumar, Santhiya Iswarya Vinothini/AAR-2150-2021 | 57746259400; 57800915900; 35205433300; 9041032900 | jypaeng@gmail.com; | JOURNAL OF STOMATOLOGY ORAL AND MAXILLOFACIAL SURGERY | J STOMATOL ORAL MAXI | 2468-8509 | 2468-7855 | 124 | 1 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2023 | 1.8 | 45.3 | 1.69 | 2025-06-25 | 5 | 5 | Secondary healing; Neoveil; PGA sheet; Polyglycolic acid sheet; Oral mucosal defects | AUTOLOGOUS FIBRIN GLUE; CLINICAL-APPLICATION; WOUND COVERINGS; RESECTION; TONGUE; POINT | Neoveil; Oral mucosal defects; PGA sheet; Polyglycolic acid sheet; Secondary healing | Absorbable Implants; Female; Fibrin Tissue Adhesive; Humans; Male; Middle Aged; Polyglycolic Acid; Precancerous Conditions; Wound Healing; fibrin glue; polyglycolic acid; biodegradable implant; female; human; male; middle aged; precancer; wound healing | English | 2023 | 2023-02 | 10.1016/j.jormas.2022.08.002 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |

| ○ | ○ | Article | Household financial health: a machine learning approach for data-driven diagnosis and prescription | Household finances are being threatened by unprecedented social and economic upheavals, including an aging society and slow economic growth. Numerous researchers and practitioners have provided guidelines for improving the financial status of households; however, the challenge of handling heterogeneous households remains nontrivial. In this study, we propose a new data-driven framework for the financial health of households to address the needs for diagnosing and improving financial health. This research extends the concept of healthcare to household finance. We develop a novel deep learning-based diagnostic model for estimating household financial health risk scores from real-world household balance sheet data. The proposed model can successfully manage the heterogeneity of households by extracting useful latent representations of household balance sheet data while incorporating the risk information of each variable. That is, we guide the model to generate higher latent values for households with risky balance sheets. We also show that the gradient of the model can be utilized for prescribing recommendations for improving household financial health. The robustness and validity of the new framework are demonstrated using empirical analyses. | Kim, Kyeongbin; Hwang, Yoontae; Lim, Dongcheol; Kim, Suhyeon; Lee, Junghye; Lee, Yongjae | Ulsan Natl Inst Sci & Technol, Dept Ind Engn, 50 UNIST Gil, Ulsan 44919, South Korea; Seoul Natl Univ, Technol Management Econ & Policy Program, 1 Gwanak Ro, Seoul 08826, South Korea; Kyungpook Natl Univ, Grad Sch Data Sci, Daegu 41566, South Korea; Seoul Natl Univ, Grad Sch Engn Practice & Technol Management, Econ & Policy Program, 1 Gwanak Ro, Seoul 08826, South Korea | ; Lee, Junghye/KUF-0668-2024; Lee, Yongjae/Q-4430-2018; hwang, yoontae/NBW-7066-2025 | 58642896200; 57900412600; 57224767610; 57216511251; 56055191300; 57092778500 | junghye@snu.ac.kr;yongjaelee@unist.ac.kr; | QUANTITATIVE FINANCE | QUANT FINANC | 1469-7688 | 1469-7696 | 23 | 11 | SSCI;SCIE | BUSINESS, FINANCE;ECONOMICS;MATHEMATICS, INTERDISCIPLINARY APPLICATIONS;SOCIAL SCIENCES, MATHEMATICAL METHODS | 2023 | 1.5 | 45.5 | 0.22 | 2025-06-25 | 1 | 1 | Household finance; Financial health; Heterogeneity; Risk scoring; Deep learning | EQUITY PREMIUM; ASSET; CONSUMPTION; MANAGEMENT; RISK | Deep learning; Financial health; Heterogeneity; Household finance; Risk scoring | English | 2023 | 2023-11-02 | 10.1080/14697688.2023.2254335 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Efficient and strategical installations of quaternary ammonium groups in metal-organic frameworks for hydroxide conductivity | Positively charged aromatic quaternary ammonium and aliphatic quaternary ammonium groups were successfully installed in metal-organic frameworks (MOFs) for hydroxide conductivity studies. Two representative solid-state MOF functionalization strategies, post-synthetic covalent modification (PSM) and post-synthetic ligand exchange (PSE), were used and their charge-loading efficiencies were compared. PSE processes were successfully performed for both aromatic and aliphatic quaternary ammonium groups, and the PSM technique was restricted to the aromatic ammonium functionalization of MOFs. Although all ammonium installations induced significantly enhanced hydroxide conductivities compared to the bare MOF, the aliphatic ammonium group via the triazole linker from the CuAAC click chemistry showed the best performance. This study discusses the practicality of PSE for MOF functionalization and the additional effects of functional group modification. | Choi, Ho Jeong; Hong, Seungpyo; Son, Younghu; Kim, Ki Tae; Kim, Cheoljae; Yoon, Minyoung; Kim, Min | Chungbuk Natl Univ, Dept Chem, Cheongju 28644, South Korea; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea | Kim, Cheoljae/GNW-6326-2022; Kim, Min/Q-9608-2019; Son, Younghu/AAX-9531-2021; KIM, KI-TAE/AAX-3175-2020; Kim, Min/D-2899-2011 | 57221859975; 57221596642; 57216839175; 56540161400; 36140227400; 25222186500; 25649767300 | myyoon@knu.ac.kr;minkim@chungbuk.ac.kr; | MOLECULAR SYSTEMS DESIGN & ENGINEERING | MOL SYST DES ENG | 2058-9689 | 8 | 5 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2023 | 3.2 | 45.7 | 0.38 | 2025-06-25 | 3 | 3 | DESIGN; EXCHANGE; FUNCTIONALIZATION; LIGAND; ION | Aromatization; Metal-Organic Frameworks; Covalent modifications; Functionalizations; Hydroxide conductivities; Ligand exchanges; Metalorganic frameworks (MOFs); Positively charged; Quaternary ammonium; Quaternary ammonium group; Solid state metals; Synthetic ligands; Aromatic compounds | English | 2023 | 2023-05-09 | 10.1039/d2me00238h | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Commercial artificial intelligence lateral cephalometric analysis: part 1-the possibility of replacing manual landmarking with artificial intelligence service | Artificial intelligence (AI) technology has recently been introduced to dentistry. AI assisted cephalometric analysis is one of its applications, and several commercial AI services have already been launched. However, the performance of these commercial services is still unclear. This study aimed to determine whether commercially available AI cephalometric analysis can replace manual analysis by human examiners. Eighty-four pretreatment lateral cephalograms were traced and examined by two orthodontists and four commercial AIs, and 13 commonly used cephalometric variables were calculated. Then, the Bland-Altman analysis was conducted to evaluate systematic and random errors between examiners. The interchangeability of an AI was determined if the random errors of the AI were smaller than the clinically acceptable limits derived from the random errors between human examiners. Finally, the inter-examiner reliability index was calculated, and Cohen's kappa was determined to assess the actual classification reliability of each examiner. The systematic errors of the AIs were clinically insignificant in general. However, the random errors of the AIs were approximately twice those of human examiners, which did not satisfy the interchangeability condition. Furthermore, even though the reliability indices of the AIs were in the good-to-excellent range, their classification reliability was unacceptable. Commercial AI is still at a level that makes it challenging to replace manual landmarking by human experts. Thus, a human examiner's landmark position review is mandatory when using commercial AIs. | Lee, Jaesik; Bae, Seong-Ryeol; Noh, Hyung-Kyu | Kyungpook Natl Univ, Sch Dent, Dept Pediat Dent, Daegu 41940, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Periodontol, Daegu 41940, South Korea | 57193887436; 58695571100; 57208229164 | hknoh@knu.ac.kr; | JOURNAL OF CLINICAL PEDIATRIC DENTISTRY | J CLIN PEDIATR DENT | 1053-4628 | 1557-5268 | 47 | 6 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE;PEDIATRICS | 2023 | 1.5 | 46.0 | 2.56 | 2025-06-25 | 6 | 10 | Cephalometric; Artificial intelligence; Accuracy; Precision; Reliability | IDENTIFICATION; RELIABILITY; AGREEMENT | Accuracy; Artificial intelligence; Cephalometric; Precision; Reliability | Artificial Intelligence; Cephalometry; Humans; Radiography; Reproducibility of Results; article; artificial intelligence; human; orthodontist; random error; reliability; systematic error; cephalometry; radiography; reproducibility | English | 2023 | 2023 | 10.22514/jocpd.2023.085 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Commercial artificial intelligence lateral cephalometric analysis: part 2-effects of human examiners on artificial intelligence performance, a pilot study | At the current technology level, a human examiner's review must be accompanied to compensate for the insufficient commercial artificial intelligence (AI) performance. This study aimed to investigate the effects of the human examiner's expertise on the efficacy of AI analysis, including time-saving and error reduction. Eighty-four pretreatment cephalograms were randomly selected for this study. First, human examiners (one beginner and two regular examiners) manually detected 15 cephalometric landmarks and measured the required time. Subsequently, commercial AI services automatically identified these landmarks. Finally, the human examiners reviewed the AI landmark determination and adjusted them as needed while measuring the time required for the review process. Then, the elapsed time was compared statistically. Systematic and random errors among examiners (human examiners, AI and their combinations) were assessed using the Bland-Altman analysis. Intraclass correlation coefficients were used to estimate the inter-examiner reliability. No clinically significant time difference was observed regardless of AI use. AI measurement error decreased substantially after the review of the human examiner. From the standpoint of the human examiner, beginners could obtain better results than manual landmarking. However, the AI review outcomes of the regular examiner were not as good as those of manual analysis, possibly due to AI-dependent landmark decisions. The reliability of AI analysis could also be improved by employing the human examiner's review. Although the time-saving effect was not evident, commercial AI cephalometric services are currently recommendable for beginners. | Lee, Jaesik; Bae, Seong-Ryeol; Noh, Hyung-Kyu | Kyungpook Natl Univ, Sch Dent, Dept Pediat Dent, Daegu 41940, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Orthodont, Daegu 41940, South Korea | 57193887436; 58695571100; 57208229164 | hknoh@knu.ac.kr; | JOURNAL OF CLINICAL PEDIATRIC DENTISTRY | J CLIN PEDIATR DENT | 1053-4628 | 1557-5268 | 47 | 6 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE;PEDIATRICS | 2023 | 1.5 | 46.0 | 1.42 | 2025-06-25 | 5 | 5 | Cephalometric; Artificial intelligence; Efficacy; Accuracy; Precision; Reliability | IDENTIFICATION; RELIABILITY; AGREEMENT | Accuracy; Artificial intelligence; Cephalometric; Efficacy; Precision; Reliability | Artificial Intelligence; Cephalometry; Humans; Pilot Projects; Radiography; Reproducibility of Results; article; artificial intelligence; controlled study; correlation coefficient; drug efficacy; human; measurement error; pilot study; random error; randomized controlled trial; reliability; cephalometry; pilot study; procedures; radiography; reproducibility | English | 2023 | 2023 | 10.22514/jocpd.2023.087 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effect of hospital case-volume on mortality after ovarian cancer surgery: a population-based retrospective cohort study | Objectives: The goal of ovarian cancer surgery has recently shifted from optimal cytoreduction to more complete resection. This study attempted to reassess and update the association between surgical case-volume and both in-hospital and long-term mortality after ovarian cancer surgery using recent data.Design: This study is a population-based retrospective cohort study. Participants/Material: Data from all adult patients who underwent ovarian cancer surgery in Korea between 2005 and 2019 were obtained from the national database. A total of 24,620 patients underwent ovarian cancer surgery in 362 hospitals during the period.Setting: In-hospital and 1, 3, 5-year mortality were set as primary and secondary outcomes.Methods: Hospitals were categorized into high-volume (>90 cases/year), medium-volume (20-90 cases/year), and low-volume (<20 cases/year) centers considering overall distribution of case-volume. Postoperative in-hospital and long-term mortality were analyzed using logistic regression after adjusting for potential risk factors. Results: Compared to high-volume centers (0.54%), in-hospital mortality was significantly higher in medium-volume (1.40%; adjusted odds ratio, 2.92; confidence interval, 1.82-3.73; P<0.001) and low-volume (1.61%; adjusted odds ratio, 2.94; confidence interval, 2.07-4.17; P<0.001) centers. In addition, 1-year mortality was 6.26%, 7.06%, and 7.94% for high-volume, medium-volume, and low-volume centers, respectively, and the differences among the groups were significant. However, case-volume effect was not apparent in 3- and 5-year mortality after ovarian cancer surgery.Limitations: Lacking clinical information such as staging or histologic diagnosis due to the nature of the administrative data should be considered in interpreting the data.Conclusions Case-volume effect was observed for in-hospital and 1-year mortality after ovarian cancer surgery while it was not clearly found in 3- or 5-year mortality. Dilution of the case-volume effect might be attributed to the high accessibility to care. | Kim, Bo Rim; Kim, Heewon; Joo, Se-gyeong; Jang, Eun Jin; Jo, Junwoo; Lee, Hannah; Ryu, Ho Geol | Korea Univ Guro Hosp, Korea Univ Coll Med, Dept Anesthesiol & Pain Med, Seoul, South Korea; Seoul Natl Univ Hosp, Seoul Natl Univ Coll Med, Dept Anesthesiol & Pain Med, Seoul, South Korea; Seoul Natl Univ Hosp, Dept Obstet & Gynecol, Seoul, South Korea; Andong Natl Univ, Dept Informat Stat, Andong, South Korea; Kyungpook Natl Univ, Dept Stat, Daegu, South Korea; Seoul Natl Univ Hosp, Seoul Natl Univ Coll Med, Dept Anesthesiol & Pain Med, Daehak ro 101, Seoul 03080, South Korea | ; Ryu, Ho/J-5463-2012; Kim, Bo Rim/AFQ-3640-2022 | 57189683654; 57219254817; 57782004000; 37861741600; 57210425017; 55634905800; 7202277246 | hogeol@gmail.com; | GYNECOLOGIC AND OBSTETRIC INVESTIGATION | GYNECOL OBSTET INVES | 0378-7346 | 1423-002X | 87 | 6 | SCIE | OBSTETRICS & GYNECOLOGY | 2023 | 2 | 46.0 | 0.57 | 2025-06-25 | 2 | 2 | CYTOREDUCTIVE SURGERY; SURVIVAL; OUTCOMES | Case-volume effect; In-hospital mortality; Long-term mortality; Ovarian cancer; Ovarian cancer surgery | Adult; Cytoreduction Surgical Procedures; Female; Hospital Mortality; Hospitals; Humans; Ovarian Neoplasms; Retrospective Studies; adjuvant chemotherapy; adult; aged; Article; cancer surgery; cohort analysis; female; high volume hospital; human; hysterectomy; in-hospital mortality; Korea; Korean (people); low volume hospital; lymph node dissection; major clinical study; mortality; national health insurance; ovary cancer; retrospective study; risk factor; salpingooophorectomy; cytoreductive surgery; hospital; hospital mortality; ovary tumor | English | 2023 | 2023-01 | 10.1159/000526833 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Evaluation of the neurofilament light chain as a biomarker in children with spinal muscular atrophy treated with nusinersen | Background: This study aimed to evaluate the neurofilament light chain (NfL) as a biomarker for treatment responses in children with a broad spectrum of spinal muscular atrophy (SMA) under nusinersen treatment.Method: We measured NfL levels in serum (sNfL) and cerebrospinal fluid (cNfL) in nusinersen-treated patients with SMA and children without neurologic disorders. Correlations between cNfL and sNfL levels and motor function scores were analyzed.Results: sNfL and cNfL levels were measured in eight patients with SMA (SMA type 1, n = 3; SMA type 2, n = 5). sNfL levels were strongly correlated with cNfL levels regardless of the SMA subtype (r = 0.97, P < 0.001). Patients with SMA type 1 had higher baseline cNfL and sNfL levels before treatment initiation than those with SMA type 2 and neurologically healthy children. In patients with acute stage of SMA type 1 and 2, the NfL level rapidly decreased during the nusinersen treatment loading phase followed by stabilization at a lower plateau level. In contrast, in a patient with a chronic stage of SMA type 2, the NfL level remained within the normal range with no apparent downward trend. Motor function scores showed a tendency toward an inverse correlation with NfL levels in patients with acute stage although not in patients with chronic stage.Conclusions: cNfL and sNfL levels can be promising biomarkers for monitoring treatment response in patients within their acute stage, particularly in SMA type 1, although not in patients with a chronic stage of SMA type 2.(c) 2023 Published by Elsevier B.V. on behalf of The Japanese Society of Child Neurology.

| ○ | ○ | Article | Foreign body ingestion trends in children in the Daegu-Kyungpook Province, Korea before and during the COVID-19 period: a repeated cross-sectional study | Background: During the coronavirus disease 2019 (COVID-19) period, children spent more time at home, which is where most foreign body ingestions (FBIs) in children occur. We compared the rate of FBI in children in the Daegu-Kyungpook Province during COVID-19 to the rate in the 2 years before the COVID-19 period. Methods: The period from January to December in the year 2020 was defined as the COVID-19 period, and the corresponding time period in 2018 and 2019 was defined as the pre-COVID-19 period. Medical records were analyzed retrospectively for pediatric patients aged 0-15 years who visited outpatient and emergency rooms at seven tertiary referral hospitals in Daegu-Kyungpook Province. Results: The annual occurrence rate of FBIs in patients visiting seven tertiary referral hospitals was not different during COVID-19 compared to that in the pre-COVID-19 period and the median age of these patients during the COVID-19 and pre-COVID-19 periods was similar. However, occurrence rates increased in the groups aged 0-3 and 4-6 years but decreased in the group aged 7-15 years during the COVID-19 period. The proportion of male patients as well as inpatients increased significantly during the COVID-19 period (both P=0.01). The proportion of foreign bodies located in the post-pyloric region increased during the COVID-19 period (P=0.02). The most common symptom, foreign body sensation in the neck, was similar in both groups. There was no significant difference in the foreign body removal method between the two groups. The occurrence rates of swallowing of toys, coins, magnets, button batteries, and superabsorbent polymers non-significantly increased; and the food ingestion rate decreased, while the non-food ingestion rate increased in all age groups during the COVID-19 period. Conclusions: The FBI rate in children did not differ during the COVID-19 period compared to that in the pre-COVID-19 period. The occurrence of FBI in boys, the number of foreign bodies located in the post-pyloric region, and the number of hospitalizations due to FBI increased during the COVID-19 period. | Hong, Suk Jin; Kim, Changho; Lee, Dong Won; Jang, Hyo Jeong; Cho, Seung Man; Choi, Kwang Hae; Hwang, Jun Hyun; Choe, Jae Young | Daegu Catholic Univ, Sch Med, Dept Pediat, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Emergency Med, 130 Dongdeok Ro, Daegu 41944, South Korea; Daegu Fatima Hosp, Dept Pediat, Daegu, South Korea; Keimyung Univ, Dept Pediat, Sch Med, Daegu, South Korea; Dongguk Univ, Dept Pediat, Sch Med, Gyeongju, South Korea; Yeungnam Univ, Yeungnam Univ Hosp, Dept Pediat, Sch Med, Daegu, South Korea; Daegu Catholic Univ, Dept Prevent Med, Sch Med, Daegu, South Korea | Lee, Dongwon/IAU-6865-2023 | 56573097000; 56441824200; 57219048083; 55355948500; 35168810700; 55040976900; 36129337200; 57023107400 | cjy@knu.ac.kr; | TRANSLATIONAL PEDIATRICS | TRANSL PEDIATR | 2224-4336 | 2224-4344 | 12 | 7 | SCIE | PEDIATRICS | 2023 | 1.5 | 46.0 | 0.33 | 2025-06-25 | 1 | 1 | Coronavirus disease 2019 (COVID-19); foreign bodies; pediatrics; emergency medicine | POISON DATA SYSTEM; PEDIATRIC GASTROENTEROLOGY; ENDOSCOPY; HEPATOLOGY; NUTRITION; SOCIETY | Coronavirus disease 2019 (COVID-19); emergency medicine; foreign bodies; pediatrics | polymer; adolescent; age distribution; Article; checklist; child; controlled study; coronavirus disease 2019; cross-sectional study; demographics; emergency ward; female; food intake; foreign body; foreign body ingestion; hospitalization; human; infant; ingestion; major clinical study; male; medical record review; neck; newborn; outpatient department; preschool child; pylorus; sensation; sex difference; South Korea; swallowing; tertiary care center; trend study | English | 2023 | 2023-07 | 10.21037/tp-23-21 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Gastric cancer with distinct Epstein-Barr virus-positive and -negative tumor components and their whole exome sequencing result: a case Report | BackgroundEpstein-Barr virus (EBV)-associated gastric cancer exhibits distinct clinicopathologic characteristics, showing a good response to immune checkpoint inhibitors and a favorable prognosis. However, gastric cancer comprising distinct EBV-positive and -negative components in a single mass have been rarely reported, and their detailed genetic characteristics have not yet been investigated. Therefore, we reported the case of gastric cancer exhibiting distinct EBV-positive and -negative areas and further investigated its genetic characteristics.Case presentationsA 70-year-old man underwent distal gastrectomy for gastric cancer, which was detected during a routine health check-up. EBV-encoded RNA in situ hybridization revealed distinct EBV-positive and -negative components at each other's borders, morphologically consistent with collision tumor. We separately sequenced EBV-positive and -negative tumor areas through whole exome sequencing (WES) with matched normal tissue. Remarkably, both EBV-positive and -negative areas shared pathogenic mutations of ARID1A, KCNJ2, and RRAS2. Furthermore, they shared 92 somatic single nucleotide variants and small insertion or deletion mutations, of which 32.7% and 24.5% are EBV-positive and -negative tumor components, respectively.ConclusionsWES results suggested that gastric cancer with distinct EBV-positive and -negative tumor components, formerly categorized as a collision tumor, can be clonally related. EBV-negative tumor component might be associated with loss of EBV during tumor progression. | Park, Ki Bum; Seo, An Na; Kim, Moonsik | Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Surg, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Pathol, 807 Hogukno, Daegu 41404, South Korea | 57220965452; 55804153700; 57195918515 | san_0729@naver.com;teiroa83@knu.ac.kr; | DIAGNOSTIC PATHOLOGY | DIAGN PATHOL | 1746-1596 | 18 | 1 | SCIE | PATHOLOGY | 2023 | 2.4 | 46.0 | 0.57 | 2025-06-25 | 2 | 2 | Epstein-Barr virus; Heterogeneity; Collision tumor; Gastric carcinoma with lymphoid stroma; Whole exome sequencing | IMMUNOHISTOCHEMICAL STAINING PATTERNS; CARCINOMA; MUTATIONS; P53 | Collision tumor; Epstein–Barr virus; Gastric carcinoma with lymphoid stroma; Heterogeneity; Whole exome sequencing | Aged; Epstein-Barr Virus Infections; Exome Sequencing; Herpesvirus 4, Human; Humans; Immune Checkpoint Inhibitors; Male; Stomach Neoplasms; immune checkpoint inhibitor; aged; case report; complication; Epstein Barr virus; Epstein Barr virus infection; genetics; human; male; stomach tumor; whole exome sequencing | English | 2023 | 2023-07-11 | 10.1186/s13000-023-01363-3 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Optimal post height and diameter in preformed zirconia crown restoration on 3D-printed primary incisors | In this in vitro study, fracture resistance was evaluated according to the post-diameter and-length in zirconia crown restorations on three-dimensional printed primary incisors undergone pulpectomy. One hundred-and-sixty primary incisor abutments were used which were artificially fabricated through 3D-printing. Each group was divided into two subgroups based on the zirconia post-diameter (1.5 mm and 2.0 mm) employed for post setting after pulpectomy. Furthermore, each group was divided into four subgroups based on the zirconia post-height (3.0, 4.0, 5.0 and 6.0 mm). Zirconia post setting was made by applying flowable resin after filling the pulp cavity with calcium hydroxide up to 3.0 mm below cemento-enamel junction (CEJ). Finally, a preformed zirconia crown of size #1 was cemented to the abutment through resin cement. A compressive load was applied to the middle palatal surface of incisors restored with zirconia crowns by using a universal testing machine at 145 degrees angle which is the normal interincisal angle of children. The root fracture specimens were excluded and the samples fractured within crown and core parts were included in the final fracture resistance analysis. The group with 1.5 -mm post-diameter and 5.0-mm post-height had the highest fracture resistance strength (130.63 +/- 55.75 N) under masticatory pressure condition. Fracture resistance was statistically greater in 5.0-mm than in 4.0-mm and 3.0-mm post-height groups for 1.5 -mm post-diameter subgroup. Moreover, 5.0-mm post-height subgroup had a statistically greater fracture resistance than that of 3.0-mm post-height subgroup for 2.0-mm post -diameter group. The 2.0-mm post-diameter subgroup had a statistically greater fracture resistance than that of 1.5-mm post-diameter subgroup for 3.0-mm and 4.0-mm post -heights. If zirconia post incorporation is required for deciduous incisor restoration, a post-length equal to facial CEJ level is recommended for gaining additional retention against masticatory pressure. | Kim, Jong -Sung; Kim, Gi-Min; Kim, Hyun-Jung; Lee, Jae-Sik | Kyungpook Natl Univ, Sch Dent, Dept Pediat Dent, Daegu 41940, South Korea | Kim, Seok-Hwan/G-9981-2015 | 58610938900; 57210885969; 57196215346; 57193887436 | leejs@knu.ac.kr; | JOURNAL OF CLINICAL PEDIATRIC DENTISTRY | J CLIN PEDIATR DENT | 1053-4628 | 1557-5268 | 47 | 5 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE;PEDIATRICS | 2023 | 1.5 | 46.0 | 0.85 | 2025-06-25 | 3 | 3 | 3D-printing; Fracture resistance; Zirconia crown; Zirconia post -setting | FRACTURE-RESISTANCE; CERAMIC POST; CORE; TEETH; STRENGTH; CHILDREN; SYSTEMS | 3D-printing; Fracture resistance; Zirconia crown; Zirconia post-setting | Child; Crowns; Dental Pulp Cavity; Humans; Incisor; Printing, Three-Dimensional; zirconium oxide; child; dental pulp cavity; human; incisor; three dimensional printing | English | 2023 | 2023 | 10.22514/jocpd.2023.053 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
