| ○ | ○ | Article | Earthwork Volume Calculation, 3D Model Generation, and Comparative Evaluation Using Vertical and High-Oblique Images Acquired by Unmanned Aerial Vehicles | In civil engineering and building construction, the earthwork volume calculation is one of the most important factors in the design and construction stages; therefore, an accurate calculation is necessary. Moreover, because managing earthworks is highly important, in this study, a three-dimensional (3D) model for earthwork calculation and management was performed using an unmanned aerial vehicle (UAV) and an RGB camera. Vertical and high-oblique images (45 degrees, 60 degrees, and 75 degrees) were acquired at 50 and 100 m heights for accurate earthwork calculations and a 3D model, and data were generated by dividing the images into eight cases. Cases 1-4 were images acquired from a height of 50 m, and cases 5-8 were images acquired from a height of 100 m. (case 1: 90 degrees, case 2: 90 degrees + 45 degrees, case 3: 90 degrees + 60 degrees, case 4: 90 degrees + 75 degrees, case 5: 90 degrees, case 6: 90 degrees + 45 degrees, case 7: 90 degrees + 60 degrees, case 8: 90 degrees + 75 degrees). Three evaluations were performed on the data. First, the accuracy was evaluated through checkpoints for the orthophoto; second, the earthwork volumes calculated via a global positioning system and UAV were compared; finally, the 3D model was evaluated. Case 2, which showed the lowest root mean square error in the orthophoto accuracy evaluation, was the most accurate. Case 2 was the most accurate in the earthwork volume evaluation and 3D model compared to other cases. Through this study, the best results were obtained when using a vertical image and a high-oblique image of 40 to 50 degrees when generating a 3D model for earthwork volume calculation and management. In addition, if the UAV is not affected by obstacles, it is better to shoot at about 50 m or less than to shoot the UAV height too high. | Lee, Kirim; Lee, Won Hee | Kyungpook Natl Univ, Dept Spatial Informat, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Convergence & Fus Syst Engn, Sangju 37224, South Korea | 57193932338; 57190774365 | wlee33@knu.ac.kr; | AEROSPACE | AEROSPACE-BASEL | 2226-4310 | 9 | 10 | SCIE | ENGINEERING, AEROSPACE | 2022 | 2.6 | 22.1 | 1.61 | 2025-06-25 | 12 | 14 | UAV; earthwork volume; high-oblique image; vertical image; 3D model | ACCURACY ANALYSIS; UAV; SFM; CAMERA; SYSTEM | 3D model; earthwork volume; high-oblique image; UAV; vertical image | English | 2022 | 2022-10 | 10.3390/aerospace9100606 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||

| ○ | ○ | Article | Validation of Relationship between Patients' Descriptions of Pruritus and Patient-burden of Chronic Pruritus using Structural Equation Modelling | Patients with chronic itch describe their pruritus in a wide variety of ways. However, these subjective descriptions are often not taken into consideration by physicians. This study aimed to validate patients' descriptions of pruritus, and to investigate the relationship between various descriptions of pruritus and the patient burden of chronic pruritus by examining the mediating effects of sleep disturbance and sexual dysfunction on patient's quality of life, as predicted by various descriptions of pruritus. Exploratory and confirmatory factor analyses were performed to identify the factor structure measured by 11 descriptions of pruritus. The study then analysed differences in the degree of sleep disturbance, sexual dysfunction, and quality of life deterioration factors using a structural equation modelling method. Using data from 419 patients with chronic pruritus, 11 descriptions of pruritus were classified into 2 groups: (i) sensory pruritus (i.e. stinging, stabbing, burning, painful, formication, throbbing, and cold) that are linked with descriptions of pruritus patterns; and (ii) affective pruritus (i.e. annoying, unbearable, worrisome, and warm) from patient reports of psychological or emotional distress. The study found that affective pruritus decreases patient's quality of life either directly or indirectly through sleep disturbance. In conclusion, clues about a patients' sleep disturbance or poor quality of life can be obtained through their descriptions of pruritus. | Ryoo, Ji Hoon; Lee, Seon Hwa; Ha, Dae-Lyong; Park, Kyung Duck; Rho, Jaehee; Park, Gyeong-Hun; Kim, Byung-Soo; Li, Kapsok; Park, Chang Ook; Kim, Hye One; Kim, Hei Sung; Jang, Min Soo; Lee, Dong Hun; Lee, Yang Won; Kim, Do Won; Jang, Yong Hyun; Kim, Seong-Jin | Yonsei Univ, Dept Educ, Seoul, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Dermatol, Daegu, South Korea; Hallym Univ, Dongtan Sacred Heart Hosp, Dept Dermatol, Coll Med, Hwaseong, South Korea; Pusan Natl Univ, Dept Dermatol, Sch Med, Busan, South Korea; Chung Ang Univ, Coll Med, Dept Dermatol, Seoul, South Korea; Yonsei Univ, Severance Hosp, Cutaneous Biol Res Inst, Dept Dermatol,Coll Med, Seoul, South Korea; Hallym Univ, Kangnam Sacred Heart Hosp, Dept Dermatol, Coll Med, Seoul, South Korea; Catholic Univ Korea, Dept Dermatol, Incheon St Marys Hosp, Incheon, South Korea; Kosin Univ, Dept Dermatol, Coll Med, Busan, South Korea; Seoul Natl Univ, Dept Dermatol, Coll Med, Seoul, South Korea; Konkuk Univ, Dept Dermatol, Sch Med, Seoul, South Korea; Chonnam Natl Univ, Dept Dermatol, Med Sch, Gwangju, South Korea | Ryoo, Ji/N-7643-2018; Lee, Jae-Hyun/ABE-3803-2020; Kim, Do-Yeon/B-1877-2009; Kim, Seong/AAV-1869-2020; Kim, Chang Gon/IAP-6721-2023; Kim, Sunuk/KJM-5211-2024; Lee, Dong Hun/AAS-6021-2021 | 56312837100; 57224078421; 57201367090; 55767995700; 57207755762; 24460704500; 55726523900; 57113935300; 57283808600; 8659715100; 9247821100; 56588449100; 55649570908; 15033490400; 57206101464; 57016046400; 57070811700 | yhjang@knu.ac.kr;seongkim@chonnam.ac.kr; | ACTA DERMATO-VENEREOLOGICA | ACTA DERM-VENEREOL | 0001-5555 | 1651-2057 | 102 | SCIE | DERMATOLOGY | 2022 | 3.6 | 22.1 | 0.36 | 2025-06-25 | 2 | 2 | chronic pruritus; description; sexual dysfunction; sleep disturbance; quality of life | QUALITY-OF-LIFE; ATOPIC-DERMATITIS; SEVERITY; INSTRUMENT; PSORIASIS; IMPACT; SCALE | chronic pruritus; description; quality of life; sexual dysfunction; sleep disturbance | Humans; Latent Class Analysis; Pain; Paresthesia; Pruritus; Quality of Life; Sleep Wake Disorders; adult; Article; chronic disease; confirmatory factor analysis; controlled study; deterioration; disease burden; emotional stress; exploratory factor analysis; female; human; major clinical study; male; middle aged; pruritus; quality of life; sexual dysfunction; sleep disorder; structural equation modeling; validation process; latent class analysis; pain; paresthesia; pruritus; psychology; quality of life; sleep disorder | English | 2022 | 2022-11 | 10.2340/actadv.v102.2527 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Tensile and High-Cycle Fatigue Properties of Extruded AZ91-0.3Ca-0.2Y Alloy with Excellent Corrosion and Ignition Resistances | Mg-Al-Zn-Ca-Y (SEN) alloys have been recently developed by adding small amounts of Ca and Y to commercial Mg-Al-Zn (AZ series) alloys. These alloys possess superior corrosion and ignition resistances to their commercial AZ series counterparts. Here, commercial AZ91 (Mg-9Al-0.8Zn, wt%) and developed SEN9 (Mg-9Al-0.8Zn-0.3Ca-0.2Y, wt%) alloys are extruded under the same conditions, and the microstructure, tensile properties, and high-cycle fatigue properties of the extruded alloys are compared. The extruded SEN9 alloy has a smaller average grain size and higher microstructural homogeneity than the extruded AZ91 alloy because the Al-2 Y, Al-2 Ca, and Al8Mn4 Y particles in the homogenized SEN9 billet promote dynamic recrystallization during extrusion. Despite their different microstructures, the two alloys possess similar tensile strengths because the strong precipitation hardening in the extruded AZ91 alloy is offset by strong grain-boundary hardening in the extruded SEN9 alloy. However, the extruded SEN9 alloy exhibits higher tensile elongation because deformation twinning is suppressed by the finer grains. The fatigue strength of the extruded SEN9 alloy (100 MPa) is slightly lower than that of the extruded AZ91 alloy (110 MPa). For the extruded AZ91 alloy, fatigue cracks initiate on the surface in all specimens, whereas for the extruded SEN9 alloy, fatigue cracks initiate in an Al2Ca or Al2Y particle present on the subsurface in some specimens, especially at low stress amplitudes. The Al2Ca and Al2Y particles are larger than the Mg17Al12 precipitates, and considerably harder than the matrix. Consequently, local stress is highly concentrated in these particles during cyclic loading, which eventually causes premature fatigue cracking and decreased fatigue resistance. | Cha, Jae Won; Kim, Ye Jin; Kim, Young Min; Bae, Jun Ho; Park, Sung Hyuk | Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea; Korea Inst Mat Sci, Adv Met Div, Chang Won 51508, South Korea | Park, Sung-Hyuk/AAE-6726-2022; Kim, Young Min/HCH-5414-2022 | 57221282466; 59052467200; 58795669000; 36900467300; 54786002500 | sh.park@knu.ac.kr; | METALS AND MATERIALS INTERNATIONAL | MET MATER INT | 1598-9623 | 2005-4149 | 28 | 2 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING | 2022 | 3.5 | 22.2 | 1.45 | 2025-06-25 | 16 | 16 | Mg-Al-Zn-Ca-Y alloy; Extrusion; Microstructure; Tensile properties; High-cycle fatigue | MECHANICAL-PROPERTIES; MICROSTRUCTURAL EVOLUTION; MAGNESIUM ALLOYS; GRAIN-SIZE; BEHAVIOR; DEFORMATION; AZ91; AZ31; TEMPERATURE; OXIDATION | Extrusion; High-cycle fatigue; Mg–Al–Zn–Ca–Y alloy; Microstructure; Tensile properties | Age hardening; Aluminum alloys; Binary alloys; Calcium alloys; Corrosion; Cracks; Dynamic recrystallization; Fatigue crack propagation; Grain boundaries; Hardening; Magnesium alloys; Manganese alloys; Microstructure; Precipitation (chemical); Stress analysis; Tensile strength; Twinning; Average grain size; Deformation twinning; Grain boundary hardening; High cycle fatigue properties; Ignition resistances; Microstructural homogeneity; Superior corrosion; Tensile elongation; Fatigue of materials | English | 2022 | 2022-02 | 10.1007/s12540-021-01101-8 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Constitutive modeling of principal stress rotation associated with sand under simple shear loading | An elasto-plastic constitutive model is proposed to account for the effect of principal stress rotation that commonly occurs and significantly influences soil behavior. The model is based on a concept of adding plastic strain increments obtained from two mobilized planes: a plane of maximum shear stress which swings as the principal stress rotates, and a horizontal plane which is spatially fixed. Models based on the plane of maximum shear stress alone are particularly sensitive to horizontal effective stress ratio K-0 (=sigma '(x)/sigma '(y)), whereas the proposed model gives a similar skeleton behavior for soils at the same density and mean effective stress, regardless of the value of K-0, as observed in laboratory tests. The model is firstly calibrated by data from drained and undrained monotonic and cyclic Direct Simple Shear (DSS) tests on K-0-consolidated specimens of Nakdong River sand in loose and dense states. The capability of the proposed model in modeling of the conventional liquefaction effects: initial shear stress condition alpha (=tau '(xy)/sigma '(y)) with K-alpha corrections, and initial confining stress condition sigma '(y) with K-sigma corrections, is also emphasized in this paper. | Park, Sung-Sik; Nong, Zhen-Zhen; Doan, Nhat-Phi | Kyungpook Natl Univ, Dept Civil Engn, Daegu, South Korea; Jiangsu Univ Sci & Technol, Sch Naval Architecture & Ocean Engn, Zhenjiang, Jiangsu, Peoples R China; Ind Univ Ho Chi Minh City, Dept Civil Engn, 12 Nguyen Van Bao,Ward 4, Ho Chi Minh City 71408, Vietnam | DOAN, NHAT-PHI/IAM-1883-2023; Doan, Nhat-Phi/IAM-1883-2023 | 36241850300; 57211377923; 58095587400 | phidoan.ksxd@gmail.com; | INTERNATIONAL JOURNAL FOR NUMERICAL AND ANALYTICAL METHODS IN GEOMECHANICS | INT J NUMER ANAL MET | 0363-9061 | 1096-9853 | 46 | 8 | SCIE | ENGINEERING, GEOLOGICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;MECHANICS | 2022 | 4 | 22.3 | 0.45 | 2025-06-25 | 5 | 5 | constitutive model; initial horizontal effective stress ratio; initial static shear stress ratio; mobilized plane; principal stress rotation; simple shear | 1998 NCEER/NSF WORKSHOPS; LIQUEFACTION RESISTANCE; SIMULTANEOUS INCREASE; LOOSE SAND; RATIO; STRENGTH; BEHAVIOR; SOILS | constitutive model; initial horizontal effective stress ratio; initial static shear stress ratio; mobilized plane; principal stress rotation; simple shear | Shear flow; Shear stress; Soil liquefaction; Stress analysis; Effective stress; Initial horizontal effective stress ratio; Initial static shear stress ratio; Maximum shear stress; Mobilized plane; Principal stress rotation; Shear stress ratio; Simple shear; Static shear stress; Stress ratio; constitutive equation; effective stress; loading; numerical model; sand; shear stress; stress analysis; Constitutive models | English | 2022 | 2022-06 | 10.1002/nag.3354 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Optimizing the performance of hybrid renewable energy systems to accelerate a sustainable energy transition in Nigeria: A case study of a rural healthcare centre in Kano | The COVID-19 pandemic brought tremendous pressure to the African continent's health sector, particularly in rural areas. Rural healthcare facilities experienced severe energy shortages due to the influx of Covid-19 patients, which strained their operating capacities. These facilities usually rely on diesel engines, and this unidirectional approach limited governments' vision in resolving the energy crisis. This paper aims to develop a hybrid energy system (HES) that combines alternate energy sources available at a rural healthcare centre in northern Nigeria and conduct a techno-economic analysis of the viability of such systems. The energy potential of available energy resources at the target location and comparison of various HES configurations were estimated with HOMER Pro software to determine the most feasible choices. These choices were analyzed for technical, financial, and environmental viability using RETScreen Expert. Due to an abundance of solar energy, low diesel cost, and sufficient wind energy potential, the results show PV - Diesel and Wind - Diesel system HES configurations as the only practical choices. Techno-economic analysis indicates that the PV - Diesel HES produces annual savings of $30,583 with a Net Present Value (NPV) of $390,949 compared to $15,174 and $193,980 for the Wind - Diesel configuration. Further analysis solidifies the PV-Diesel HES as the best choice with a payback period of 1.3 years, 75 tons of CO2 emission reduction, and annual savings of $30,583 compared to the initial diesel energy system. | Yakub, Abdulfatai Olatunji; Same, Noel Ngando; Owolabi, Abdulhameed Babatunde; Nsafon, Benyoh Emmanuel Kigha; Suh, Dongjun; Huh, Jeung-Soo | Kyungpook Natl Univ, Inst Global Climate Change & Energy, Dept Energy Convergence & Climate Change, Dept Convergence & Fus Syst Engn, Daegu 41566, South Korea; Inst Global Climate Change & Energy, Dept Energy Convergence & Climate Change, Daegu, South Korea | 57894905100; 57895613600; 57192210107; 57211664452; 36613529600; 7102258915 | Yakubabdulfatai1@gmail.com;Samenoel1@gmail.com;Owolabiabdulhameed@gmail.com;luxnsafon@gmail.com;dongjunsuh@knu.ac.kr;jshuh@knu.ac.kr; | ENERGY STRATEGY REVIEWS | ENERGY STRATEG REV | 2211-467X | 2211-4688 | 43 | SCIE | ENERGY & FUELS | 2022 | 8.2 | 22.3 | 3.01 | 2025-06-25 | 31 | 40 | Hybrid energy systems; Sustainable energy transition; HOMER; RETScreen; Payback period; Emission | PHOTOVOLTAIC POWER; CLIMATIC ZONES | Emission; HOMER; Hybrid energy systems; Payback period; RETScreen; Sustainable energy transition | Diesel engines; Economic analysis; Emission control; Energy conservation; Energy policy; Health care; Investments; Solar energy; Wind power; Emission; Energy systems; Energy transitions; HOMER; Hybrid energy system; Payback periods; RETScreen; Sustainable energy; Sustainable energy transition; Techno-Economic analysis; Rural areas | English | 2022 | 2022-09 | 10.1016/j.esr.2022.100906 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Patients presenting high fever with lymphadenopathy after COVID-19 vaccination were diagnosed with hemophagocytic lymphohistiocytosis | Background The coronavirus disease 2019 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is still continuing worldwide. Currently, two mRNA-based vaccines and two DNA vaccines using an adenovirus vector are representative vaccines. Since the SARS-CoV-2 vaccines began to be administered, a significant decrease in new infections and COVID-19-associated death has been reported. However, various adverse events from mild symptoms to death have also been described after vaccination. Case description Patients with high fever and lymphadenopathy who are diagnosed with hemophagocytic lymphohistiocytosis (HLH) after COVID-19 vaccination are very rare, and there is no standard management guideline for these patients thus far. Herein, we described two cases of HLH after the administration of an mRNA-based vaccine and adenovirus vector vaccine. Discussion HLH is a life-threatening hyperinflammatory syndrome that occurs due to persistent stimulation of lymphocytes and histiocytes in various underlying conditions at all ages. Although the exact mechanisms and risk factors of COVID-19 vaccination-related HLH are still unknown, vigorous immune stimulation may trigger a huge cytokine storm, rarely resulting in HLH. It is important to note that early suspicion by clinicians can lower the mortality rate. | Baek, Dong Won; Hwang, Soyoon; Kim, Juhyung; Lee, Jung Min; Cho, Hee Jeong; Moon, Joon-Ho; Hwang, Narae; Jeong, Ji Yun; Lee, Sang-Woo; Sohn, Sang Kyun | Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Hematol Oncol, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Infect Dis, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Lab Med, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Pathol, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Nucl Med, Daegu, South Korea | lee, sangwoo/KUD-1906-2024; Lee, Jung-Min/L-8227-2016 | 57191874272; 57203160675; 58739544500; 57211561890; 57216754907; 56568642700; 57224639090; 57205472984; 57196249819; 13310226800 | sksohn@knu.ac.kr; | INFECTIOUS DISEASES | INFECT DIS-NOR | 2374-4235 | 2374-4243 | 54 | 4 | SCIE | INFECTIOUS DISEASES | 2022 | 5.8 | 22.4 | 1.71 | 2025-06-25 | 17 | 15 | COVID-19; vaccination; lymphadenopathy; fever; hemophagocytic lymphohistiocytosis | COVID-19; fever; hemophagocytic lymphohistiocytosis; lymphadenopathy; vaccination | COVID-19; COVID-19 Vaccines; Humans; Lymphadenopathy; Lymphohistiocytosis, Hemophagocytic; SARS-CoV-2; Vaccination; apixaban; bnt 162 b 2; dexamethasone; etoposide; ferritin; tozinameran; vaxzevria; adult; aged; angiography; Article; case report; clinical article; computer assisted tomography; coronavirus disease 2019; cytokine storm; disease severity; excisional biopsy; female; fever; follow up; hemophagocytic syndrome; histiocyte; human; hypertension; hypotension; immunostimulation; liver dysfunction; lymphadenopathy; lymphocyte; male; medical examination; mortality rate; motor dysfunction; myalgia; nausea; neutropenia; nuclear magnetic resonance imaging; pandemic; positron emission tomography; rash; risk factor; slurred speech; splenomegaly; tachycardia; thrombocytopenia; vaccination; vein thrombosis; young adult; hemophagocytic syndrome; lymphadenopathy; vaccination | English | 2022 | 2022-04-03 | 10.1080/23744235.2021.2010801 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | A GMOS/IFU Study of Jellyfish Galaxies in Massive Clusters | Jellyfish galaxies are an intriguing snapshot of galaxies undergoing ram pressure stripping (RPS) in dense environments, showing spectacular star-forming knots in their disks and tails. We study the ionized gas properties of five jellyfish galaxies in massive clusters with Gemini GMOS/Integral Field Unit observations: MACSJ0916-JFG1 (z = 0.330), MACSJ1752-JFG2 (z = 0.353), A2744-F0083 (z = 0.303), MACSJ1258-JFG1 (z = 0.342), and MACSJ1720-JFG1 (z = 0.383). "Baldwin, Phillips, and Terlevich" diagrams show that star formation, active galactic nuclei (AGNs), or mixed effects are ionizing gas in these galaxies. Radial velocity distributions of ionized gas seem to follow disk rotation of galaxies, with the appearance of a few high-velocity components in the tails as a sign of RPS. Mean gas velocity dispersion is lower than 50 km s(-1) in most star-forming regions except near AGNs or shock-heated regions, indicating that the ionized gas is dynamically cold. Integrated star formation rates (SFRs) of these galaxies range from 7 M (circle dot) yr(-1) to 35 M (circle dot) yr(-1), and the tail SFRs are from 0.6 M (circle dot) yr(-1) to 16 M (circle dot) yr(-1), which are much higher than those of other jellyfish galaxies in the local universe. These high SFR values imply that RPS triggers intense star formation activity in these extreme jellyfish galaxies. The phase-space diagrams demonstrate that the jellyfish galaxies with higher stellar masses and higher host cluster velocity dispersion are likely to have more enhanced star formation activity. The jellyfish galaxies in this study have similar gas kinematics and dynamical states to those in the local universe, but they show a much higher SFR. | Lee, Jeong Hwan; Lee, Myung Gyoon; Mun, Jae Yeon; Cho, Brian S.; Kang, Jisu | Seoul Natl Univ, SNUARC, Dept Phys & Astron, Astron Program, 1 Gwanak Ro, Seoul 08826, South Korea; Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Daegu 41566, South Korea; Australian Natl Univ, Res Sch Astron & Astrophys, Canberra, ACT 2611, Australia | 57195344163; 7409116688; 57222089861; 57215605904; 56574541700 | joungh93@snu.ac.kr;mglee@astro.snu.ac.kr; | ASTROPHYSICAL JOURNAL | ASTROPHYS J | 0004-637X | 1538-4357 | 940 | 1 | SCIE | ASTRONOMY & ASTROPHYSICS | 2022 | 4.9 | 22.5 | 0.08 | 2025-06-25 | 2 | 1 | STAR-FORMATION ACTIVITY; STRIPPING EVENTS; MUSE VIEW; MATTER; DARK; GAS; EVOLUTION; STELLAR; CORE; DYNAMICS | English | 2022 | 2022-11-01 | 10.3847/1538-4357/ac9276 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | A Mid-infrared Flare in the Seyfert Galaxy NGC 3786: A Changing-look Event Triggered by an Obscured Tidal Disruption Event? | We report an exceptional mid-infrared flare in the Seyfert 1.8 NGC 3786. In the multiepoch data from the Wide-field Infrared Survey Explorer, the nuclear mid-infrared brightness of NGC 3786 appears to vary substantially up to 0.5-0.8 mag around mid-2020. However, there is no evidence of significant variation in the corresponding light curve of the optical band from the Zwicky Transient Facility. This implies that the flare may have been heavily obscured by nuclear dust. Through follow-up spectroscopic observations with Gemini-North after the flare, we find that broad emission lines in Pa alpha and Pa beta newly appear, while the broad H beta emission is marginally detected in the postflare spectrum. In addition, their central wavelengths are systematically redshifted up to 900 km s(-1) with respect to the narrow emission lines. This reveals that the flare is associated with the changing-look phenomenon from type 1.8 to type 1. Based on these findings, we argue that the flare is likely to originate from an obscured tidal disruption event, although extreme variation in the accretion rate may not be ruled out completely. | Son, Suyeon; Kim, Minjin; Ho, Luis C.; Kim, Dohyeong; Kim, Taehyun | Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Daegu 41566, South Korea; Peking Univ, Kavli Inst Astron & Astrophys, Beijing 100871, Peoples R China; Peking Univ, Sch Phys, Dept Astron, Beijing 100871, Peoples R China; Pusan Natl Univ, Dept Earth Sci, Busan 46241, South Korea | Kim, Minjin/AAU-9910-2020 | 57226328130; 56898213300; 57225302746; 55574223678; 57050549000 | mkim.astro@gmail.com; | ASTROPHYSICAL JOURNAL | ASTROPHYS J | 0004-637X | 1538-4357 | 937 | 1 | SCIE | ASTRONOMY & ASTROPHYSICS | 2022 | 4.9 | 22.5 | 0.17 | 2025-06-25 | 2 | 2 | ACTIVE GALACTIC NUCLEI; BLACK-HOLE MASSES; BROAD-LINE REGION; BOLOMETRIC LUMINOSITY; MULTIWAVELENGTH; STELLAR; STAR; DECOMPOSITION; DISTRIBUTIONS; CONSTRAINTS | English | 2022 | 2022-09-01 | 10.3847/1538-4357/ac8a9d | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | B-fields in Star-forming Region Observations (BISTRO): Magnetic Fields in the Filamentary Structures of Serpens Main | We present 850 mu m polarimetric observations toward the Serpens Main molecular cloud obtained using the POL-2 polarimeter on the James Clerk Maxwell Telescope as part of the B-fields In STar-forming Region Observations survey. These observations probe the magnetic field morphology of the Serpens Main molecular cloud on about 6000 au scales, which consists of cores and six filaments with different physical properties such as density and star formation activity. Using the histogram of relative orientation (HRO) technique, we find that magnetic fields are parallel to filaments in less-dense filamentary structures where NH2 < 0.93 x 10(22) cm(-2) (magnetic fields perpendicular to density gradients), while they are perpendicular to filaments (magnetic fields parallel to density gradients) in dense filamentary structures with star formation activity. Moreover, applying the HRO technique to denser core regions, we find that magnetic field orientations change to become perpendicular to density gradients again at NH2 approximate to 4.6 x 10(22) NH2 approximate to 16 x 10(22) cm(-2), magnetic fields change back to being parallel to density gradients once again, which can be understood to be due to magnetic fields being dragged in by infalling material. In addition, we estimate the magnetic field strengths of the filaments (B-POS = 60-300 mu G)) using the Davis-Chandrasekhar-Fermi method and discuss whether the filaments are gravitationally unstable based on magnetic field and turbulence energy densities. | Kwon, Woojin; Pattle, Kate; Sadavoy, Sarah; Hull, Charles L.

| ○ | ○ | Article | Determination of Sodium Abundance Ratio from Low-resolution Stellar Spectra and Its Applications | We present a method to determine sodium abundance ratios ([Na/Fe]) using the Na i D doublet lines in low-resolution (R similar to 2000) stellar spectra. As stellar Na i D lines are blended with those produced by the interstellar medium, we developed a technique for removing the interstellar Na i D lines using the relationship between extinction, which is proportional to E(B - V), and the equivalent width of the interstellar Na i D absorption lines. When measuring [Na/Fe], we also considered corrections for nonlocal thermodynamic equilibrium (NLTE) effects. Comparisons with data from high-resolution spectroscopic surveys suggest that the expected precision of [Na/Fe] from low-resolution spectra is better than 0.3 dex for stars with [Fe/H] > -3.0. We also present a simple application employing the estimated [Na/Fe] values for a large number of stellar spectra from the Sloan Digital Sky Survey (SDSS). After classifying the SDSS stars into Na-normal, Na-high, and Na-extreme, we explore their relation to stars in Galactic globular clusters (GCs). We find that while the Na-high SDSS stars exhibit a similar metallicity distribution function (MDF) to that of the GCs, indicating that the majority of such stars may have originated from GC debris, the MDF of the Na-normal SDSS stars follows that of typical disk and halo stars. As there is a high fraction of carbon-enhanced metal-poor stars among the Na-extreme stars, they may have a non-GC origin, perhaps due to mass-transfer events from evolved binary companions. | Koo, Jae-Rim; Lee, Young Sun; Park, Hye-Jin; Kim, Young Kwang; Beers, Timothy C. | Chungnam Natl Univ, Dept Astron & Space Sci, Daejeon 34134, South Korea; Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Daegu 41566, South Korea; Sejong Univ, Dept Phys & Astron, Seoul 05006, South Korea; Univ Notre Dame, Dept Phys, Notre Dame, IN 46556 USA; Univ Notre Dame, JINA Ctr Evolut Elements, Notre Dame, IN 46556 USA | ; Beers, Timothy/D-1193-2019 | 15127066700; 42262812000; 57272110400; 57478595500; 7005881539 | youngsun@cnu.ac.kr; | ASTROPHYSICAL JOURNAL | ASTROPHYS J | 0004-637X | 1538-4357 | 925 | 1 | SCIE | ASTRONOMY & ASTROPHYSICS | 2022 | 4.9 | 22.5 | 0.25 | 2025-06-25 | 6 | 3 | METAL-POOR STARS; GLOBULAR-CLUSTER SYSTEM; DIGITAL SKY SURVEY; MILKY-WAY; RICH STARS; SEGUE; DISCOVERY; HALO; ABSORPTION; ACCRETION | English | 2022 | 2022-01-01 | 10.3847/1538-4357/ac3423 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||

We carried out submillimeter observations using the SCUBA-2 camera at the James Clerk Maxwell Telescope and obtained flux or an upper limit at 450 and 850 mu m for each target. By experimenting with the effect of the AGN dust component in the SED fit, we find that the dust luminosity can be overestimated if the AGN contribution is ignored. While the SFR based on the 4000 angstrom break shows a significant offset compared to the dust-luminosity-based SFR, the SFR obtained by the artificial neural network generally shows consistency, albeit with a large scatter. We find that SFR correlates with the AGN outflow strength manifested by the [O iii] lambda 5007 emission line, and that AGNs with higher Eddington ratios and stronger outflows are generally hosted by galaxies with a higher SFR, which is consistent with the correlation reported by Woo et al. This suggests no instantaneous quenching of star formation due to AGN feedback. | Kim, Changseok; Woo, Jong-Hak; Jadhav, Yashashree; Chung, Aeree; Baek, Junhyun; Lee, Jeong Ae; Shin, Jaejin; Hwang, Ho Seong; Luo, Rongxin; Son, Donghoon; Kim, HyunGi; Woo, Hyuk | Seoul Natl Univ, Dept Phys & Astron, Astron Program, 1 Gwanak Ro, Seoul 08826, South Korea; Seoul Natl Univ, SNU Astron Res Ctr, 1 Gwanak Ro, Seoul 08826, South Korea; Yonsei Univ, Dept Astron, 50 Yonsei Ro, Seoul 03722, South Korea; Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Daegu 41566, South Korea | ; Lee, Jeong/G-7361-2012; HWANG, Ho/AAS-6010-2020; Woo, Jong-Hak/A-2790-2014 | 57476223300; 7401751171; 57226852976; 8100674200; 56915271300; 36782468900; 55554622900; 15131707100; 55659290900; 35222498700; 57476185900; 57476223400 | woo@astro.snu.ac.kr; | ASTROPHYSICAL JOURNAL | ASTROPHYS J | 0004-637X | 1538-4357 | 928 | 1 | SCIE | ASTRONOMY & ASTROPHYSICS | 2022 | 4.9 | 22.5 | 0.59 | 2025-06-25 | 10 | 7 | COMPLEX STRUCTURE; SDSS GALAXIES; AGN; DUST; EVOLUTION; EMISSION; ASTROPY; SCUBA-2 | English | 2022 | 2022-03-01 | 10.3847/1538-4357/ac5407 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Hard X-Ray Emission in Centaurus A | We use 13 yr of Swift/BAT observations to probe the nature and origin of the hard X-ray (14-195 KeV) emission in Centaurus A. Since the beginning of the Swift operation in 2004, significant X-ray variability in the 14-195 KeV band has been detected, with mild changes in the source spectrum. Spectral variations became more eminent after 2013, following a softer-when-brighter trend. Using the power spectral density (PSD) method, we find that the observed hard X-ray photon flux variations are consistent with a red-noise process of slope, -1.3, with no evidence for a break in the PSD. We find a significant correlation between the hard X-ray and 230 GHz radio flux variations, with no time delay longer than 30 days. The temporal and spectral analysis confirms that the X-ray emission generated by the accretion in the ADAF model is sub-dominant as compared with the emission arsiing from that produced by the inner regions of the radio jet. | Rani, B.; Mundo, S.

| ○ | ○ | Article | Measurement of High-energy Cosmic-Ray Proton Spectrum from the ISS-CREAM Experiment | The Cosmic Ray Energetics And Mass for the International Space Station (ISS-CREAM) experiment successfully recorded data for 539 days from 2017 August to 2019 February. We report the energy spectrum of cosmic-ray protons from the ISS-CREAM experiment at energies from 1.60 x 10(3) to 6.55 x 10(5) GeV. The measured spectrum deviates from a single power law. A smoothly broken power-law fit to the data, including statistical and systematic uncertainties, shows the spectral index change at 9.0 x 10(3) GeV from 2.57 +/- 0.03 to 2.82 +/- 0.02 with a significance of greater than 3 sigma. This bump-like structure is consistent with a spectral softening recently reported by the balloon-borne CREAM, DAMPE, and NUCLEON, but ISS-CREAM extends measurements to higher energies. | Choi, G.
