| ○ | ○ | Article | SmartFormer: Graph-based transformer model for energy load forecasting | Electric load forecasting is a pivotal component in the power industry, providing essential intelligence for optimizing smart grid operations. Energy load data, inherently characterized as a multivariate time series, is influenced by various interdependent factors such as weather conditions, economic activity, and seasonal variations, all of which significantly impact the overall load dynamics. Though deep learning techniques, particularly with transformer-based models, have achieved significant progress in forecasting time series data, a gap exists in adequately acknowledging the importance of inter-series dependencies in multi-series load data. This paper proposes a novel graph-nested transformer model to effectively capture inter-series dependencies and forecast the load using a graph structure. The proposed Transformer model addresses two primary challenges: efficiently representing various temporal patterns and reducing redundant information within the series. In the proposed model, the graph neural network components are seamlessly integrated into the Transformer layers, allowing for the fusion of sequence encoding and graph aggregation in an iterative workflow. Evaluations across four distinct datasets demonstrate the superiority of the proposed model over state-of-the-art techniques in power load forecasting. | Saeed, Faisal; Rehman, Abdul; Shah, Hasnain Ali; Diyan, Muhammad; Chen, Jie; Kang, Jae-Mo | Shenzhen Univ, Coll Comp Sci & Software Engn, Shenzhen 518060, Guangdong, Peoples R China; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Artificial Intelligence, Daegu 41566, South Korea; Teesside Univ, Dept Comp & Games, Middlesbrough, England | ; Rehman, Abdul/KCZ-1929-2024; Diyan, Muhammad/AAM-5848-2021 | 58165089300; 57200894071; 57762344700; 26028317800; 57212281942; 56024930400 | jmkang@knu.ac.kr; | SUSTAINABLE ENERGY TECHNOLOGIES AND ASSESSMENTS | SUSTAIN ENERGY TECHN | 2213-1388 | 2213-1396 | 73 | SCIE | ENERGY & FUELS;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2024 | 7 | 26.0 | 2.1 | 2025-05-07 | 2 | 2 | Power industry; Graph neural network; Self-attention; Transformers; Load forecasting; Smart grid | Graph neural network; Load forecasting; Power industry; Self-attention; Smart grid; Transformers | Energy; Graph neural networks; Graph-based; Load data; Load forecasting; Power industry; Self-attention; Smart grid; Transformer; Transformer modeling; artificial neural network; energy market; energy use; forecasting method; smart grid; time series analysis | English | 2025 | 2025-01 | 10.1016/j.seta.2024.104133 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | Circadian clock regulation in soybean senescence: a transcriptome analysis of early and late senescence types | BackgroundPlant senescence is the process of physiological maturation of plants and is important for crop yield and quality. Senescence is controlled by several factors, such as temperature and photoperiod. However, the molecular basis by which these genes promote senescence in soybeans is not well understood. We identified senescence-related genes via transcriptome analysis of early-senescence (ES)- and late-senescence (LS)-type plants to elucidate the molecular mechanisms of senescence in soybeans.ResultsWe obtained early-senescence (ES)- and late-senescence (LS)-type F7 plants from a cross between a hybrid (Glycine max x Glycine soja) and the Glycine max cultivar. The ES-type plants presented the reproductive (R2) growth stage at 50 days after sowing (DAS) and the R7 growth stage at 95 DAS, whereas the LS-type plants presented the beginning of the R1 and R6 growth stages at 50 and 95 DAS, respectively. To understand the molecular mechanisms underlying this senescence, we performed transcriptome analysis of leaves from 50 to 95 DAS of ES- and LS-type plants. A total of 2,414 and 2,471 genes at 50 and 95 DAS, respectively, were differentially expressed between ES-type and LS-type plants. Twenty-three candidate genes associated with the circadian clock, chlorophyll biosynthesis, phytohormones, and senescence-associated protein kinases were identified, and their expression levels were analyzed. In addition, to understand interaction between circadian clock and senescence, we analyzed expression patterns of seven circadian clock-related genes during the time period (light and dark condition): CIRCADIAN CLOCK ASSOCIATED 1 (CCA1), LATE ELONGATED HYPOCOTYL (LHY), CONSTANS-LIKE 9 (COL9), LUX ARRHYTHMO (LUX) EARLY FLOWERING 3 (ELF3), PSEUDO-RESPONSE REGULATOR5 (PRR5) and GIGANTEA (GI). The expression patterns of circadian clock-related genes were similar in the ES- and LS-type plants. However, the transcription levels of these genes were compared between ES- and LS-type plants, and the expression of these genes was greater than that in LS-type plants during the period when expression increased. Therefore, each set of candidate genes regulated senescence in each plant by regulating their expression level.ConclusionsThese findings provide novel insights into the regulation of senescence in soybean plants, which could lead to the development of new strategies to improve agriculture. | Basnet, Prakash; Lee, Sevin; Moon, Ka Hee; Park, Nam-Il; Lee, Gang-Seob; Lee, Seongkon; Um, Taeyoung; Choi, Ik-Young | Kangwon Natl Univ, Dept Agr & Life Ind, Chunchon 2434, South Korea; Gangneung Wonju Natl Univ, Dept Plant Sci, Kangnung 25457, South Korea; Kyungpook Natl Univ, Dept Coastal Agr Res Inst, Daegu 41566, South Korea; Rural Dev Adm, Natl Acad Agr Sci, Dept Agr Biotechnol, Jeonju 54874, South Korea; Kangwon Natl Univ, Agr & Life Sci Res Inst, Chunchon 24341, South Korea | CHOI, Ik-Young/ABI-6938-2020 | 57219932310; 59366628300; 59357417000; 35071692900; 25927158200; 37056895800; 56754885900; 11340068900 | prakashbasnet2007@kangwon.ac.kr; huko1541@kangwon.ac.kr; moonkahee0633@kangwon.ac.kr; nipark@gwnu.ac.kr; kangslee0227@gmail.com; goryeong@korea.kr; taeyoung@kangwon.ac.kr; choii@kangwon.ac.kr; | BMC GENOMICS | BMC GENOMICS | 1471-2164 | 26 | 1 | SCIE | GENETICS & HEREDITY;BIOTECHNOLOGY & APPLIED MICROBIOLOGY | 2024 | 3.7 | 26.4 | 0 | 2025-05-07 | 0 | 0 | Soybean; Inbred lines; Senescence; Circadian clock; Transcriptome analysis | INDUCED LEAF SENESCENCE; PSEUDO-RESPONSE REGULATORS; CHLOROPHYLL DEGRADATION; NUTRIENT REMOBILIZATION; PLANT SENESCENCE; ZINC-FINGER; ARABIDOPSIS; PROTEIN; GENE; EXPRESSION | Circadian clock; Inbred lines; Senescence; Soybean; Transcriptome analysis | Circadian Clocks; Gene Expression Profiling; Gene Expression Regulation, Plant; Glycine max; Plant Leaves; Plant Proteins; Plant Senescence; Transcriptome; deoxyribonuclease I; genomic DNA; nucleic acid binding protein; porphyrin; protein kinase; transcriptome; plant protein; transcriptome; Arabidopsis; Article; circadian clock regulation; circadian rhythm; drug mechanism; human; KEGG; light intensity; mRNA expression level; nonhuman; phenotype; plant senescence; protein binding; protein degradation; protein phosphorylation; real time reverse transcription polymerase chain reaction; RNA sequencing; senescence; soybean; soybean senescence; gene expression profiling; gene expression regulation; genetics; growth, development and aging; metabolism; plant leaf; plant senescence | English | 2025 | 2025-01-21 | 10.1186/s12864-024-11095-3 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Genome diversity, population structure and MALDI-TOF MS profiling of Aspergillus oryzae/flavus strains from fermentation and wild environments | Various strains of Aspergillus oryzae, regarded as a domesticated variant of aflatoxigenic Aspergillus flavus, are utilized in the soybean fermentation industry of Korea. This study compared A. oryzae/flavus strains isolated from various environments in Korea including industrial settings, Meju (brick of dried fermented soybeans), and wild conditions with globally reported strains using genomic analysis to determine their taxonomic positions and risk of mycotoxicity. Using population genomics, five distinct groups (A to E) were identified, with all aflatoxigenic Korean strains in Group C and non-aflatoxigenic Korean strains in Groups A, B, and E. Korean strains from Meju and wild conditions are distributed across Groups A and B, and most of the Korean industrial strains form a sub-cluster with Japanese industrial strains in Group A. Comparing secondary metabolite gene cluster mutation pattern, three gene clusters (Aflatoxin, Cyclopiazonic acid and Ditryptophenaline) were revealed as group specific ones. In aflatoxin and cyclopiazonic acid clusters, most of the Group C strains had intact regions compared to strains in other groups. Since most of the Group C strains produce aflatoxin and have intact Aflatoxin and Cyclopiazonic acid gene clusters, we considered that this group represent A. flavus. Profiling using MALDI-TOF MS analysis also distinguished Group C from Groups A, B and E by specific three proteomic peaks. Among the three peaks, those around 12,700 to 12,900 m/z (Da) are expected to correspond to AflF (nor B), an enzyme involved in Aflatoxin metabolism. These results showed taxonomic positions of Korean strains of A. oryzae/flavus from various environments and also showed possibility to differentiate between A. oryzae and A. flavus with genome and MALDI-TOF MS analysis. | Kim, Dong-Hyun; Kim, Dong-Chan; Seo, Donggun; Kim, Ki-Tae; Lee, Sang-Han; Hong, Seung-Beom | RDA, Natl Inst Agr Sci, Agr Microbiol Div, Korean Agr Culture Collect, Wanju 55365, South Korea; Kyungpook Natl Univ, Dept Food Sci & Biotechnol, Daegu 41566, South Korea; NQ Lab Inc, Div Med Device R&D, Yongin 16827, South Korea; Sunchon Natl Univ, Dept Agr Life Sci, Sunchon 57922, South Korea | 57994755300; 59368628400; 59368304300; 57202965736; 57221453703; 35198177100 | sang@knu.ac.kr; funguy@korea.kr; | BMC GENOMICS | BMC GENOMICS | 1471-2164 | 26 | 1 | SCIE | GENETICS & HEREDITY;BIOTECHNOLOGY & APPLIED MICROBIOLOGY | 2024 | 3.7 | 26.4 | 0 | 2025-05-07 | 0 | 0 | Genomics; Aspergillus oryzae/flavus complex; Structure analysis; Aflatoxin; MALDI-TOF | FLAVUS; BIOSYNTHESIS; MEJU | Aflatoxin; Aspergillus oryzae/flavus complex; Genomics; MALDI-TOF; Structure analysis | Aflatoxins; Aspergillus flavus; Aspergillus oryzae; Fermentation; Genetic Variation; Genome, Fungal; Genomics; Indoles; Multigene Family; Phylogeny; Republic of Korea; Spectrometry, Mass, Matrix-Assisted Laser Desorption-Ionization; aflatoxin; cyclopiazonic acid; indole derivative; Article; Aspergillus oryzae; controlled study; cross validation; DNA extraction; environment; fermentation; gene linkage disequilibrium; genetic variability; genomics; matrix assisted laser desorption ionization time of flight mass spectrometry; maximum likelihood method; nonhuman; phylogenetic tree; population structure; single nucleotide polymorphism; structure analysis; taxonomy; wild environment; Aspergillus flavus; classification; fungal genome; genetic variation; genetics; isolation and purification; matrix-assisted laser desorption-ionization mass spectrometry; metabolism; multigene family; phylogeny; South Korea | English | 2025 | 2025-04-30 | 10.1186/s12864-025-11596-9 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Genome Sequencing of Rare Disease Patients Through the Korean Regional Rare Disease Diagnostic Support Program | Affecting fewer than 20,000 people as defined in South Korea, rare diseases pose significant diagnostic challenges due to their diverse manifestations and genetic heterogeneity. Genome sequencing (GS) offers a promising solution by enabling simultaneous screening for thousands of rare genetic disorders. This study explores the diagnostic utility and necessity of GS within the government-funded Korean Regional Rare Disease Diagnostic Support Program (KR-RDSP), a collaborative initiative involving 11 regional rare disease centers across Korea. The program was launched as a proof-of-concept study in 2023 to equip the genetic clinics with a diagnostic tool to expedite the diagnoses for rare disease patients who reside outside the urban Seoul region where diagnostic resources are limited. The study leveraged GS to diagnose a cohort of 400 patients exhibiting a wide spectrum of symptoms. The overall diagnostic yield was 36.3% (145/400), with 4.8% (7/145) of the diagnosed patients being reported with variants that could not have been identified by chromosomal microarray or exome sequencing (ES), highlighting the added value of comprehensive genomic analysis. The implementation of a centralized GS analysis system streamlined the diagnostic process, enabling timely reporting within a reasonable turnaround time of <= 35 days. Segregation analysis by Sanger sequencing played a crucial role in confirming or reclassifying variant pathogenicity by elucidating inheritance patterns. Here, we summarize diagnostic statistics from the 400 GS dataset gathered from June 2023 to December 2023 and show interesting and informative case examples that illustrate the diagnostic efficacy of GS, highlighting its ability to uncover elusive genetic etiologies and provide personalized treatment insights. The study also highlights the successful implementation of the program for the 11 regional rare disease centers across Korea with a practical workflow, comprehensive testing, comparable diagnostic yield to previous reports, and, most importantly, reasonable turnaround time. | Khang, Rin; Lee, Hane; Kim, Jihye; Moon, Dongseok; Jang, Seokhui; Lee, Eugene; Song, Yongjun; Ryu, Seung Woo; Lee, Sohyun; Han, Heonjong; Kim, Sukwon; Jang, Sohyun; Sohn, Young Bae; Kim, Won Seop; Lee, Ji-Eun; Kim, Juwon; Cho, Yonggon; Lee, Bo Lyun; Lim, Han Hyuk; Kook, Hoon; Kang, Ki-Soo; Kwon, Soonhak; Lee, Jiwon; Seo, Go Hun; Oh, Seung Hwan; Cheon, Chong Kun | 3Billion Inc, Med Genet Div, Seoul, South Korea; 3billion Inc, Res & Dev Ctr, Seoul, South Korea; Ajou Univ, Sch Med, Ajou Univ Hosp, Dept Med Genet,Rare Dis Ctr Southern Gyeonggi Reg, Suwon, South Korea; Chungbuk Natl Univ Hosp, Rare Dis Ctr Chungbuk Reg, Dept Pediat, Cheongju, South Korea; Inha Univ Hosp, Rare Dis Ctr Northwestern Gyeonggi Prov, Dept Pediat, Incheon, South Korea; Yonsei Univ, Wonju Coll Med, Wonju Severance Christian Hosp, Rare Dis Ctr Gangwon Reg, Wonju, South Korea; Jeonbuk Natl Univ Hosp, Jeonbuk Reg Ctr Rare Dis, Dept Lab Med, Jeonju, South Korea; Inje Univ, Busan Paik Hosp, Coll Med, Dept Pediat,Coll Med, Busan 633165, South Korea; Chungnam Natl Univ, Chungnam Natl Univ Hosp, Dept Radiol, Dept Pediat,Coll Med, Daejeon, South Korea; Chonnam Natl Univ Hwasun Hosp, Rare Dis Ctr Chonnam Reg, Dept Pediat, Gwangju, South Korea; Jeju Natl Univ, Jeju Natl Univ Hosp, Rare Dis Ctr Jeju Reg, Dept Pediat,Coll Med, Jeju, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Childrens Hosp, Rare Dis Ctr Daegu Gyeongbuk Reg, Daegu, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Childrens Hosp, Dept Pediat, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Daegu, South Korea; Korea Dis Control & Prevent Agcy, Div Rare Dis Management, Cheongju, South Korea; Pusan Natl Univ, Pusan Natl Univ Yangsan Hosp, Dept Lab Med, Sch Med, Yangsan, South Korea; Pusan Natl Univ, Pusan Natl Univ Childrens Hosp, Rare Dis Ctr Gyeongnam Reg, Dept Pediat,Sch Med, Yangsan, South Korea | ; Lim, Han Hyuk/AFT-1442-2022; Cheon, Chong Kun/GLU-0305-2022 | 56310395100; 9746013300; 59448914700; 57200175629; 57222558713; 57705058300; 58261082700; 57072394700; 59562951500; 56688001500; 57575038900; 59563121300; 56457557700; 36677553400; 56813210000; 57207437257; 57712996300; 24553938600; 36986990700; 7006255531; 59705406100; 55468232200; 59705224300; 57062033100; 59705224400; 26649396100 | paracelsus@daum.net; chongkun@pusan.ac.kr; | HUMAN MUTATION | HUM MUTAT | 1059-7794 | 1098-1004 | 2025 | 1 | SCIE | GENETICS & HEREDITY | 2024 | 3.7 | 26.4 | 0 | 2025-05-07 | 0 | 0 | VARIANTS; GENETICS | Female; Genetic Testing; Genome, Human; Genomics; Humans; Male; Rare Diseases; Republic of Korea; Whole Genome Sequencing; adolescent; adult; Article; body dysmorphic disorder; bone disease; cardiovascular disease; child; chromosome analysis; cohort analysis; congenital disorder; controlled study; diagnostic value; endocrine disease; eye disease; female; funding; gastrointestinal disease; gene sequence; genetic disorder; hematologic disease; human; immunopathology; infant; kidney disease; liver disease; major clinical study; male; mental disease; metabolic disorder; microarray analysis; molecular diagnosis; neurologic disease; newborn; pathogenicity; pilot study; preschool child; proof of concept; rare disease; Sanger sequencing; school child; segregation analysis; skin disease; South Korea; tumor syndrome; turnaround time; urban area; urinary tract disease; whole exome sequencing; diagnosis; genetic screening; genetics; genomics; human genome; procedures; rare disease; South Korea; whole genome sequencing | English | 2025 | 2025 | 10.1155/humu/6096758 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Highly sensitive voltammetric detection of 4-nitrobenzoic acid using Zn2SnO4/porous graphene oxide nanosheets composite electrode | Detecting 4-nitrobenzoic acid (4-NBA) is crucial due to its prevalence as an industrial pollutant and associated health hazards. In this study, we synthesized a novel stannate-based nanocomposite, Zn2SnO4/porous graphene oxide nanosheets (Zn2SnO4/PGO), through a facile hydrothermal method followed by ultrasonication-assisted dispersion. For the first time, this Zn2SnO4/PGO nanocomposite was employed as an electrode modifier for 4-NBA detection. The structural and physicochemical properties of the synthesized Zn2SnO4/PGO nanocomposite were systematically characterized using various spectroscopic techniques. Electrochemical studies, including electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), and differential pulse voltammetry (DPV), demonstrated that the Zn2SnO4/PGO-modified electrode has a significantly enhanced electroactive surface area and efficient electron transport, resulting in superior electrocatalytic activity for 4-NBA detection. From the DPV quantification experiments, the limit of detection was calculated as 3.3 nM within the linear detection range of 0.1–231 μM. The sensor demonstrated high accuracy, repeatability, reproducibility, and long-term stability. Anti-interference studies indicated no significant cathodic potential shifts in the presence of common interfering species. Finally, the Zn2SnO4/PGO-modified sensor was successfully applied to detect 4-NBA in real samples, including human urine, river water, and wastewater, showing excellent recovery rates. These findings confirm the sensor's potential for reliable and sensitive electrochemical monitoring of 4-NBA in different matrices, underscoring the importance of environmental safety and public health protections. © 2025 Elsevier B.V. | Balasubramanian, Kavitha; Alagarsamy, Saranvignesh; Raj, Michael Ruby; Chen, Shen Ming; Seemaladinne, Ramanjaneyulu; Gandhiraj, J.; Cheemalapati, Srikanth; Karuppiah, Chelladurai; Yang, Chun-Chen; Ramaraj, Sayee Kannan | PG and Research Department of Chemistry, Thiagarajar College, Affiliated to Madurai Kamaraj University, Tamil Nadu, Madurai, 625009, India; Department of Chemical Engineering and Biotechnology, National Taipei University of Technology, No. 1, Section 3, Chung-Hsiao East Road, Taipei, 106, Taiwan; School of Chemical Engineering, Yeungnam University, Gyeongsan-Si, 38541, South Korea; Department of Chemical Engineering and Biotechnology, National Taipei University of Technology, No. 1, Section 3, Chung-Hsiao East Road, Taipei, 106, Taiwan; Department of Chemistry, School of Applied Sciences and Humanities, Vignan's Foundation for Science, Technology and Research (VFSTR) Deemed to be University, Vadlamudi, Andhra Pradesh, Guntur, 522213, India; Department of Chemistry, Ramakrishna Mission Vivekananda College, Mylapore, Chennai, 600004, India; Department of Chemical Engineering and Biotechnology, National Taipei University of Technology, No. 1, Section 3, Chung-Hsiao East Road, Taipei, 106, Taiwan, PAI Pharma, R&D, Bridgewater, 08807, NJ, United States; Department of Chemistry and Green-Nano Materials Research Center, Kyungpook National University, 80 Daehakro, Buk-gu, Daegu-City, 41566, South Korea, Center of Molecular Medicine and Dianostics (COMManD), Saveetha Dental College and Hospitals, SIMTS, Saveetha University, Tamil Nadu, Chennai, 600 077, India; Battery Research Center of Green Energy, Ming Chi University of Technology, New Taipei City, 24301, Taiwan; PG and Research Department of Chemistry, Thiagarajar College, Affiliated to Madurai Kamaraj University, Tamil Nadu, Madurai, 625009, India | 57901032200; 57699618400; 57218300638; 58788922100; 57194761743; 59970592000; 55337829900; 55910716400; 35241314100; 57191341839 | smchen78@ms15.hinet.net; kcdurai.rmd@gmail.com; | FlatChem | FLATCHEM | 2452-2627 | 2452-2627 | 52 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 6.2 | 26.4 | 0 | 4-Nitrobenzoic acid; Environmental monitoring; Modified electrode; Porous graphene oxide; Voltammetric sensor; Zn<sub>2</sub>SnO<sub>4</sub> | English | Final | 2025 | 10.1016/j.flatc.2025.100906 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | ○ | Article | Insights into the nuclear-organelle DNA integration in Cicuta virosa (Apiaceae) provided by complete plastid and mitochondrial genomes | BackgroundGene transfer between the organelles and the nucleus plays a central role in shaping plant genome evolution. The identification and analysis of nuclear DNA of plastid (NUPTs) and mitochondrial (NUMTs) origins are important for exploring the extent of intracellular DNA transfer in genomes.ResultsWe report the complete plastid and mitochondrial genomes (plastome and mitogenome) of Cicuta virosa (Apiaceae) as well as a draft nuclear genome using high-fidelity (HiFi) PacBio sequencing technologies. The C. virosa plastome (154,449 bp) is highly conserved, with a quadripartite structure, whereas the mitogenome (406,112 bp) exhibits two chromosomes (352,718 bp and 53,394 bp). The mitochondrial-encoded genes (rpl2, rps14, rps19, and sdh3) were successfully transferred to the nuclear genome. Our findings revealed extensive DNA transfer from organelles to the nucleus, with 6,686 NUPTs and 6,237 NUMTs detected, covering nearly the entire plastome (99.93%) and a substantial portion of the mitogenome (77.04%). These transfers exhibit a range of sequence identities (80-100%), suggesting multiple transfer events over evolutionary timescales. Recent DNA transfer between organelles and the nucleus is more frequent in mitochondria than that in plastids.ConclusionsThis study contributes to the understanding of ongoing genome evolution in C. virosa and underscores the significance of the organelle-nuclear genome interplay in plant species. Our findings provide valuable insights into the evolutionary processes that shape organelle genomes in Apiaceae, with implications for broader plant genome evolution. | Park, Seongjun; Hwang, Yong; Kim, Heesoo; Choi, Kyoungsu | Yeungnam Univ, Inst Nat Sci, Gyongsan 38541, Gyeongbuk, South Korea; Nakdonggang Natl Inst Biol Resources, Divers Conservat Res Dept, Biol Specimen Conservat Div, Sangju 37242, Gyeongbuk, South Korea; Nakdonggang Natl Inst Biol Resources, Divers Conservat Res Dept, Dives Forecast & Evaluat Div, Sangju 37242, Gyeongbuk, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Dept Biol, Daegu 41566, South Korea | 56174240800; 57223012097; 58419765200; 59510703100 | seongjun.og@gmail.com; hdragon@nnibr.re.kr; heesookim@nnibr.re.kr; choiks010@knu.ac.kr; | BMC GENOMICS | BMC GENOMICS | 1471-2164 | 26 | 1 | SCIE | GENETICS & HEREDITY;BIOTECHNOLOGY & APPLIED MICROBIOLOGY | 2024 | 3.7 | 26.4 | 0 | 2025-05-07 | 1 | 1 | Nuclear DNAs of plastid and mitochondrial origin; Intracellular DNA transfer | GENE-TRANSFER; EVOLUTION; INSERTIONS | Intracellular DNA transfer; Nuclear DNAs of plastid and mitochondrial origin | Apiaceae; Cell Nucleus; DNA, Plant; Evolution, Molecular; Genome, Mitochondrial; Genome, Plant; Genome, Plastid; Phylogeny; Plastids; ribosomal protein s11; ribosomal protein s14; ribosomal protein s19; ribosomal protein s2; ribosomal proteins L2; ribosome protein; succinate dehydrogenase; unclassified drug; plant DNA; Angelica; Article; Bupleurum; carrot; chromosome; Cicuta virosa; coriander; Cuminum; DNA extraction; DNA integration; gene transfer; high-fidelity simulation; intracellular gene transfer; intron; mitochondrial genome; nonhuman; nuclear organelle DNA integration; Oenanthe; phylogeny; plastid genome; Apiaceae; cell nucleus; genetics; molecular evolution; plant genome; plastid | English | 2025 | 2025-02-03 | 10.1186/s12864-025-11230-8 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Machine learning assessment of zoonotic potential in avian influenza viruses using PB2 segment | BackgroundInfluenza A virus (IAV) is a major global health threat, causing seasonal epidemics and occasional pandemics. Particularly, Influenza A viruses from avian species pose significant zoonotic threats, with PB2 adaptation serving as a critical first step in cross-species transmission. A comprehensive risk assessment framework based on PB2 sequences is necessary, which should encompass detailed analyses of specific residues and mutations while maintaining sufficient generality for application to non-PB2 segments.ResultsIn this study, we developed two complementary approaches: a regression-based model for accurately distinguishing among risk groups, and a SHAP-based risk assessment model for more meaningful risk analyses. For the regression-based risk models, we compared various methodologies, including tree ensemble methods, conventional regression models, and deep learning architectures. The optimized regression model, combined with SHAP value analysis, identified and ranked individual residues contributing to zoonotic potential. The SHAP-based risk model enabled intra-class analyses within the zoonotic risk assessment framework and quantified risk yields from specific mutations.ConclusionExperimental analyses demonstrated that the Random Forest regression model outperformed other models in most cases, and we validated the target value settings for risk regression through ablation studies. Our SHAP-based analysis identified key residues (271A, 627K, 591R, 588A, 292I, 684S, 684A, 81M, 199S, and 368Q) and mutations (T271A, Q368R/K, E627K, Q591R, A588T/I/V, and I292V/T) critical for zoonotic risk assessment. Using the SHAP-based risk assessment model, we found that influenza A viruses from Phasianidae showed elevated zoonotic risk scores compared to those from other avian species. Additionally, mutations I292V/T, Q368R, A588T/I, V598A/I/T, and E/V627K were identified as significant mutations in the Phasianidae. These PB2-focused quantitative methods provide a robust and generalizable framework for both rapid screening of avians' zoonotic potential and analytical quantification of risks associated with specific residues or mutations. | Kim, Sangwook; Kim, Min-Ah; Kim, Bitgoeul; Lee, Jisu; Jung, Se-Kyung; Kim, Jonghong; Chung, Ho-Young; Lee, Chung-Young; Jeong, Sungmoon | Kyungpook Natl Univ Hosp, Biomed Res Inst, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Microbiol, Daegu, South Korea; Keimyung Univ, Dongsan Med Ctr, Dept Neurol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Med Informat, Daegu, South Korea; Kyungpook Natl Univ, Untreatable Infect Dis Inst, Daegu, South Korea; Kyungpook Natl Univ Hosp, Res Ctr Artificial Intelligence Med, Daegu, South Korea | 59377738500; 59749485100; 59749648500; 59749808900; 59749648600; 57022250500; 56008255800; 57195422071; 23100090400 | cylee87@knu.ac.kr; jeongsm00@gmail.com; | BMC GENOMICS | BMC GENOMICS | 1471-2164 | 26 | 1 | SCIE | GENETICS & HEREDITY;BIOTECHNOLOGY & APPLIED MICROBIOLOGY | 2024 | 3.7 | 26.4 | 0 | 2025-05-07 | 0 | 0 | Influenza A virus; Avian influenza virus; PB2; Artificial intelligence; Machine learning; SHAP; Mutation analysis | A VIRUS; TRANSMISSION; ADAPTATION; CELLS | Artificial intelligence; Avian influenza virus; Influenza A virus; Machine learning; Mutation analysis; PB2; SHAP | Animals; Birds; Humans; Influenza A virus; Influenza in Birds; Machine Learning; Mutation; Risk Assessment; RNA-Dependent RNA Polymerase; Viral Proteins; Zoonoses; RNA directed RNA polymerase; viral protein; ablation therapy; accuracy; Article; artificial intelligence; avian influenza; avian influenza virus; deep learning; gene mutation; global health; human; Influenza A virus; Influenza virus; machine learning; nonhuman; pathogenicity; Phasianidae; random forest; regression model; risk assessment; risk model; zoonotic transmission; animal; bird; chemistry; genetics; Influenza A virus; mutation; virology; zoonosis | English | 2025 | 2025-04-23 | 10.1186/s12864-025-11589-8 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Noise-Reduced WSe2 Phototransistors for Enhanced Photodetection Performance via Suppression of Metal-Induced Gap States | Phototransistors are critical components in optoelectronics, and 2D transition metal dichalcogenides (TMDC), such as tungsten diselenide (WSe2), show promise for phototransistor applications due to their strong light-matter interaction, unique excitonic properties, and high surface-to-volume ratio. In 2D TMDC-based phototransistors, 1/f noise, caused by complex defect states, acts as a dominant low-frequency noise (LFN) and is crucial for obtaining accurate photodetection characteristics. However, many studies still overlook LFN and focus on enhancing photocurrent or response time. In this study, the importance of LFN analysis is highlighted in WSe2 phototransistors and demonstrate reduced noises and enhanced photodetection performance through the suppression of metal-induced gap states (MIGS) that act as noise sources by utilizing semimetal bismuth (Bi) contact. The WSe2 phototransistors demonstrated approximate to 1000 times lower noise, 100 times higher responsivity, and 10 times higher specific detectivity than devices with conventional metal contacts. The results of this study suggest that reducing LFN in photodetection devices, such as by suppressing MIGS, can be an efficient way to enhance device performance. | Ryoo, Sunggyu; Sim, Jinwoo; Jeong, Seungjun; Jang, Juntae; Woo, Jaeyong; Park, Jaehyoung; Ko, Seongmin; Kim, Yeeun; Song, Youngmin; Yoo, Jongeun; Ahn, Heebeom; Kang, Keehoon; Cho, Daeheum; Cho, Kyungjune; Lee, Takhee | Seoul Natl Univ, Dept Phys & Astron, Seoul 08826, South Korea; Seoul Natl Univ, Inst Appl Phys, Seoul 08826, South Korea; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea; Seoul Natl Univ, Dept Mat Sci & Engn, Res Inst Adv Mat, Seoul 08826, South Korea; Univ Cambridge, Dept Mat Sci & Met, 27 Charles Babbage Rd, Cambridge CB3 0FS, England; Seoul Natl Univ, Res Inst Adv Mat, Inst Appl Phys, Dept Mat Sci & Engn, Seoul 08826, South Korea; Korea Inst Sci & Technol, Convergence Res Ctr Solut Electromagnet Interferen, Seoul 02792, South Korea; MIT, Dept Elect Engn & Comp Sci, 77 Massachusetts Ave, Cambridge, MA 02139 USA | Kang, Keehoon/W-9664-2018; Lee, Takhee/AAR-9632-2021; Kang, Keehoon/AGB-9894-2022 | 59188870800; 59188793600; 59523138200; 58280606700; 57219663401; 36068041600; 59072379500; 57218761714; 59523480200; 59069910000; 57207363129; 56062418000; 59510667800; 56956109300; 55731236400 | kcho@kist.re.kr; tlee@snu.ac.kr; | ADVANCED MATERIALS TECHNOLOGIES | ADV MATER TECHNOL-US | 2365-709X | 10 | 9 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 6.2 | 26.4 | 0 | 2025-05-07 | 0 | 0 | low-frequency noise; metal-induced gap states; phototransistors; semimetal; transition metal dichalcogenides | MONOLAYER; MOS2 | low-frequency noise; metal-induced gap states; phototransistors; semimetal; transition metal dichalcogenides | Bismuth compounds; Germanium compounds; Indium phosphide; Layered semiconductors; Photodetectors; Tungsten compounds; Critical component; Excitonic properties; High surface-to-volume ratio; Light-matter interactions; Low-Frequency Noise; Metal-induced gap state; Performance; Photo detection; Transition metal dichalcogenides (TMD); Tungsten diselenide; Phototransistors | English | 2025 | 2025-05 | 10.1002/admt.202500064 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Reconfigurable Planar Huygens' Metasurface for Wide Beamforming | Huygens' metasurfaces (HMSs), which independently control electric and magnetic dipole responses, have been implemented in planar platforms. However, dynamically controlling both dipole responses to achieve reconfigurability at the sub-wavelength scale remains challenging with conventional planar HMSs. In this work, these challenges are addressed by introducing the first planar, reconfigurable HMS design that integrates varactors and embedded bias lines, allowing for precise and independent control of electric and magnetic surface impedances at the sub-wavelength scale (λ0/9.4 × λ0/6.3 × λ0/22.7) at 5.5 GHz. A large-aperture HMS (4.47λ0 × 4.47λ0), integrated with 3,528 varactors and fed by a 4 × 4 patch array at a focal-length-to-diameter ratio of 1.6, demonstrates wide beamforming angles ranging from −70° to +70° with an aperture efficiency of 21.09%. This innovative design offers a promising solution for efficient and compact reconfigurable intelligent surfaces, paving the way for advanced wave control in next-generation wireless communication and sensing applications. © 2025 Wiley-VCH GmbH. | Lee, Sangmin; Choi, Sangjo | The School of Electronic and Electrical Engineering, Kyungpook National University, Daegu, 41566, South Korea; The School of Electronic and Electrical Engineering, Kyungpook National University, Daegu, 41566, South Korea | 57213176293; 36697690200 | sangjoc@knu.ac.kr; | Advanced Materials Technologies | ADV MATER TECHNOL-US | 2365-709X | 2365-709X | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 6.2 | 26.4 | 0 | 2025-05-07 | 0 | Beamforming; Huygens' metasurface; reconfigurable intelligent surface | Beam forming networks; Beamforming; Bias line; Huygen' metasurface; Huygens; Metasurface; Precise control; Reconfigurability; Reconfigurable; Reconfigurable intelligent surface; Sub-wavelength; Wavelength scale; Varactors | English | Article in press | 2025 | 10.1002/admt.202402131 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Article | Effectiveness of the Mindfulness-Based Social-Emotional Growth (MSEG) Program in Enhancing Mental Health of Elementary School Students in Korea | Since the COVID-19 pandemic, mental health challenges among children and adolescents in South Korea have intensified with rising rates of depression and suicide. Proactive interventions focusing on mental well-being are needed to address this critical issue. This study examines the effectiveness of the Mindfulness-based Social-Emotional Growth (MSEG) program for enhancing the mental health of elementary school students in Korea. This quasi-experimental study evaluated the impact of the MSEG program on students at an elementary school in Gyeonggi-do, South Korea. A total of 70 students (35 from lower grades [grades 1-3] and 35 from upper grades [grades 4-6]) participated in the 12-week intervention group, while 72 students were in the control group. Pre- and post-intervention assessments measured social-emotional, mindfulness, and clinical domains. The findings revealed significant improvements in emotional regulation across all grades. Lower-grade students showed substantially reduced anxiety and depression, while upper-grade students demonstrated enhanced resilience compared to the control group. These results indicate the potential of the MSEG program to promote early mental health when integrated into elementary school curricula. Further research is needed to adapt the program to diverse educational settings and optimize its effectiveness and impact. | Kim, Jongtae; Kim, Seonyeop; Kim, Misan W.

| ○ | ○ | Article | Spatial Compression in Memory: How Repeated Walks on Familiar Routes Shorten Perceived Distance | Many experiments on distance perception have revealed that there is a difference between perceptual distance and objective distance. It has been accepted that a route with more memorable features will make its perceived distance longer. This study revisited this information storage model and examined how estimations change by repeated journeys in a university campus. While the outcome confirms the existing hypothesis, an unexpected pattern of distance compression by time was found. Spending more years on the campus, the estimation tended to decrease. The rate of decrease was bigger and more distinctively gradual for architecture and female students than non-architecture and male students. At the end, a cognitive threshold hypothesis was suggested as a possible model to explain the complexity of distance perception. Before reaching it, the distance grows along with the knowledge on a route but beyond the point of knowledge saturation, it begins to compress. | Seo, Kyung Wook; Lee, Hyung-Sook; Kim, Joo Young | Northumbria Univ, Dept Architecture & Built Environm, Newcastle Upon Tyne NE1 8ST, England; Kyungpook Natl Univ, Dept Landscape Architecture, Daegu 41561, South Korea; Siheung Res Inst, 11 Soraesan Gil, Siheung Si 14902, South Korea | 55035682900; 35210890100; 57141245400 | kyung.seo@northumbria.ac.uk; soolee@knu.ac.kr; jooyoung@shri.re.kr; | BEHAVIORAL SCIENCES | BEHAV SCI-BASEL | 2076-328X | 15 | 4 | SSCI | PSYCHOLOGY, MULTIDISCIPLINARY | 2024 | 2.5 | 26.5 | 0 | 2025-05-07 | 0 | 0 | cognitive threshold; information storage model; repeated journey; distance compression; spatial perception | PERCEPTION; DIRECTION | cognitive threshold; distance compression; information storage model; repeated journey; spatial perception | English | 2025 | 2025-03-22 | 10.3390/bs15040404 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Functional Potential and Network-Based Insights into the Rhizosphere Microbiomes of Quercus mongolica and Larix kaempferi Stands | Evaluating forest functional indicators is essential for effective forest management planning. In this study, we conducted a metagenome-based comparative analysis of the rhizosphere soils from a natural Quercus mongolica stand and an artificial Larix kaempferi stand on Mt. Gariwang, Pyeongchang, Republic of Korea. Both stands originally belonged to the same natural forest and represent the current dominant tree species. Bacterial communities were affected more by climate than by tree species. A bacterial co-occurrence network analysis showed more complex interactions in the Q. mongolica than in L. kaempferi. Conversely, fungal communities were affected more by tree species than by climate. Specifically, the Q. mongolica stand had a high ratio of saprotrophic fungi, whereas the L. kaempferi stand exhibited a higher ratio of fungi associated with nutrient decomposition and harbored a high proportion of fungi that form ectomycorrhizae with long-distance exploration types. These fungal traits serve as indicators of soil ecological changes in Q. mongolica and L. kaempferi stands. Our comparative analysis of the microbial communities of Q. mongolica and L. kaempferi, representative plantation species in the Republic of Korea, revealed seasonal and host species-specific bacterial and fungal associations, and fungal communities were less variable than bacterial communities and more accurately reflected host tree traits. | Lee, Seok Hui; Park, Jun Young; Jeon, Su Hong; Kim, Dae Sol; Lee, Su Ho; Park, Yeong Dae; Kang, Jun Won | Kyungpook Natl Univ, Sch Forest Sci & Landscape Architecture, Dept Forestry, Daegu 41566, South Korea; Daegu Univ, Dept Forest Resources, Gyongsan 38453, South Korea | 58419182700; 58418511600; 58421874800; 58420519800; 59426213900; 7405375245; 35224649300 | svbreqwaiu@naver.com; paul05241@naver.com; tnghd8802@naver.com; skyds4499@naver.com; lsh94@daegu.ac.kr; parkyd@daegu.ac.kr; jwkang15@knu.ac.kr; | FORESTS | FORESTS | 1999-4907 | 16 | 6 | SCIE | FORESTRY | 2024 | 2.5 | 26.6 | 0 | 0 | diversity; forests; Haliangium; keystone taxa; Larix kaempferi; microbiome; Quercus mongolica | FOREST; SOIL; COMMUNITY; BACTERIA; LITTER | diversity; forests; Haliangium; keystone taxa; Larix kaempferi; microbiome; Quercus mongolica | Bacteria; Ecology; Fungi; Larix Leptolepis; Quercus Mongolica; Kangwon; Pyeongchang; South Korea; Bacteria; Biotic; Ecology; Fungi; Soils; Community IS; Diversity; Forest; Functionals; Haliangium; Keystone taxon; Larix kaempferi; Microbiome; Quercus mongolica; Tree species; deciduous forest; keystone species; rhizobacterium; rhizosphere; soil microorganism; stand structure; Forestry | English | 2025 | 2025-05-23 | 10.3390/f16060883 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | Article | Graphical Representation of Zadeh’s Max-Min Composition Operator for Two 3-Dimensional Quadratic Fuzzy Numbers | We computed the extended operations for generalized quadratic fuzzy sets and extended quadratic fuzzy numbers from R to R2. By defining parametric operations between two α-cuts, which are regions, we derived the parametric operations for two quadratic fuzzy numbers defined on R2. The outcomes of these parametric operations serve as a generalization of Zadeh’s extended algebraic operations. We demonstrated that the results obtained from the parametric operations represent an extension of Zadeh’s extended algebraic operations. Additionally, we expanded quadratic fuzzy numbers initially defined in two dimensions to three dimensions and calculated Zadeh’s max-min composition operator for two extended three-dimensional quadratic fuzzy numbers. We presented an illustrative example of three-dimensional results along with corresponding graphs. © 2025 The Author(s). | Yun, Yong Sik; Lee, BongJu | Department of Mathematics, Jeju National University, Jeju, 63243, South Korea; Department of Mathematics Education, Kyungpook National University, Daegu, 41566, South Korea | 7201731116; 56178581400 | leebj@knu.ac.kr; | European Journal of Pure and Applied Mathematics | EUR J PURE APPL MATH | 1307-5543 | 1307-5543 | 18 | 1 | ESCI | MATHEMATICS | 2024 | 1 | 26.6 | 6.72 | 2025-05-07 | 1 | 3-dimensional quadraric fuzzy number; Graphic representation; parametric operation | English | Final | 2025 | 10.29020/nybg.ejpam.v18i1.5601 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Article | The Efficacy of Simulator Technology for Forwarder Operator Training: A Preliminary Study in South Korea | Simulator training offers a safe and cost-effective approach to providing new operators opportunities to become familiar with operating modern machinery. However, in Korea, the current programs are insufficient in training skilled operators capable of handling advanced forestry machinery. Consequently, these programs fall short of developing the required technical expertise, leading to difficulties in workforce employment. We compared the performance of simulator-trained participants with that of machine-trained participants by testing operators on real equipment and assessing their stress levels. Participants were categorized as those with and without excavator certificates. Within each category, participants were further divided into those receiving training via simulators or those who were trained using actual equipment. Although we detected no significant differences in the overall performance of simulator- and machine-trained participants, compared with real machine training, simulator training promoted better performance, lower levels of frustration, and a reduced mental workload due to the safer and more controlled virtual environment. These findings can be used to develop more effective training programs by incorporating simulator-based modules that enhance skill acquisition whilst reducing risks. They can also inform policy decisions to improve workforce training in industries dependent on the operation of advanced machinery, thereby ensuring that operators achieve higher levels of competence and safety. | Lee, Eunjai; Mun, Hoseong; Lim, Heemin; Park, Sangjun | Yeungnam Univ, Dept Forest Resources, Gyongsan 38541, South Korea; Natl Inst Forest Sci, Forest Technol & Management Res Ctr, Pochoen 11186, South Korea; Kyungpook Natl Univ, Dept Forestry, Daegu 41566, South Korea | 56995405700; 57211068897; 57222960516; 57209022140 | ejay.lee@yu.ac.kr; munhs@korea.kr; heemin@knu.ac.kr; sjupark@knu.ac.kr; | FORESTS | FORESTS | 1999-4907 | 16 | 6 | SCIE | FORESTRY | 2024 | 2.5 | 26.6 | 0 | 0 | ground-based harvesting system; performance test; excavator certificates; performance; safety | excavator certificates; ground-based harvesting system; performance; performance test; safety | Cost Effectiveness; Excavators; Forestry; Performance; Personnel Training; South Korea; Construction equipment; Cost effectiveness; Excavators; Forestry; Personnel; Personnel training; Virtual reality; Excavator certificate; Ground-based harvesting; Ground-based harvesting system; Harvesting system; Operator training; Performance; Performance tests; Simulator technology; Simulator training; South Korea; employment; performance assessment; policy analysis; safety; training; Accident prevention | English | 2025 | 2025-05-23 | 10.3390/f16060882 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
