| ○ | ○ | Article | Public effect of the 2022 Colorectal Cancer Awareness Campaign delivered through a metaverse platform | Purpose: The Korean Society of Coloproctology has been conducting Colorectal Cancer Awareness Campaign, also known as the Gold Ribbon Campaign, every September since 2007. The 2022 campaign was held through a metaverse platform targeting the younger age group under the slogan of raising awareness of early -onset colorectal cancer (CRC). This study aimed to analyze the impact of the 2022 campaign on a metaverse platform. Methods: Anonymized survey data were collected from participants in the metaverse campaign from September 1 to 15, 2022. The satisfaction score of the participants was evaluated by sex, age group, and previous campaign participation status. Results: During the campaign, 2,770 people visited the metaverse. Among them, 455 people participated in the survey (response rate, 16.4%). Approximately 95% of the participants reported being satisfied with the information provided by the campaign, understood the necessity of undergoing screening for and prevention of early -onset CRC, and were familiar with the structure of the metaverse. The satisfaction score for campaign information tended to decrease as the participants' age increased. When the participants' overall level of satisfaction with the metaverse platform was assessed, teenagers scored particularly lower than the other age groups. The satisfaction scores for CRC information provided in the metaverse, as well as the scores for recognizing the seriousness and necessity of screening for early -onset CRC, indicated a high positive tendency (P < 0.001). Conclusion: Most of the 2022 Gold Ribbon Campaign participants were satisfied with the metaverse platform. Medical society should pay attention to increasing participation in and satisfaction with future public campaigns. {GRAPHIACAL ABSTRACT} | Lee, Tae-Gyun; Song, Gil-Hyeon; Ahn, Hong -min; Oh, Heung-Kwon; Byun, Moonkyoung; Han, Eon Chul; Kim, Sohyun; Kim, Chang Woo; Kim, Hye Jin; Hong, Samin; Song, Kee-Ho; Kim, Chan Wook; Cho, Yong Beom | Seoul Natl Univ, Bundang Hosp, Dept Surg, Seongnam, South Korea; Seoul Natl Univ, Dept Med, Coll Med, Seoul, South Korea; Sungkyunkwan Univ, Dept Appl Artificial Intelligence, Seoul, South Korea; Dongnam Inst Radiol & Med Sci, Colorectal Div Gen Surg, Busan, South Korea; Yeungnam Univ, Coll Med, Dept Surg, Daegu, South Korea; Ajou Univ, Dept Colorectal Surg, Sch Med, Suwon, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Colorectal Canc Ctr, Daegu, South Korea; 365 Hang Surg Clin, Seoul, South Korea; Seoul DHU Surg Clin, Seoul, South Korea; Univ Ulsan, Coll Med, Asan Med Ctr, Dept Surg, Seoul, South Korea; Sungkyunkwan Univ, Sch Med, Samsung Med Ctr, Dept Surg, 81 Irwon ro, Seoul 06351, South Korea; Seoul Natl Univ, Coll Med, Dept Surg, Bundang Hosp, 82 Gumi ro 173beon gil, Seongnam 13620, South Korea | ; Byun, Moonkyoung/LSK-7774-2024; Kim, Chang Woo/G-5001-2015; Cho, Yong/F-4606-2014; Oh, Heung-Kwon/S-1292-2019; Kim, Hye/W-1059-2019; Kim, Chang/G-5001-2015 | 58560392900; 59120472400; 57218762260; 36246541800; 57195357109; 59118719200; 39361754400; 57205308396; 57204567554; 59116926000; 59635031100; 55966571500; 55363735500 | crsohk@gmail.com;gscyb@skku.edu; | ANNALS OF COLOPROCTOLOGY | ANN COLOPROCTOL | 2287-9714 | 2287-9722 | 40 | 2 | ESCI | GASTROENTEROLOGY & HEPATOLOGY;SURGERY | 2024 | 2.1 | 32.5 | 2.59 | 2025-05-07 | 4 | 4 | Online social networks; Colorectal neoplasms; Health campaigns; Early detection of cancer; Cancer screening | Cancer screening; Colorectal neoplasms; Early detection of cancer; Health campaigns; Online social networks | adult; aged; Article; awareness; colorectal cancer; controlled study; female; human; male; medical society; middle aged; satisfaction | English | 2024 | 2024-04 | 10.3393/ac.2023.00122.0017 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Realization of giant superstructural chirality at broadband optical wavelengths via perovskite dielectric metasurfaces | Recently, perovskite materials have gained much attention for their potential in large chirality applications, particularly in chiral photonics and metamaterials. However, the intended chirality response is not achieved due to the substantial size disparity and the limited interactions between the structures and the wavelength of light. To overcome these limitations, we propose a planar all-dielectric nanostructure-based metasurface integrated with perovskite to realize exceptional superstructural chirality in the broadband visible regime. A low-loss dielectric hydrogenated amorphous silicon (a-Si:H) and the perovskite cesium lead bromide (CsPbBr3) are used to design this giant superstructural chiral perovskite metasurface. Due to the strong interaction of light with the proposed chiral perovskite metasurface and tuning of the electric and magnetic multipolar resonances, it achieved the maximum anisotropy factor of similar to 1.55 and the circular dichroism of similar to 42 934 (mdeg), almost reaching the theoretical limit of 2.0 and 45 000 (mdeg), respectively. This perovskite integration with dielectric chiral metasurfaces could pave the way for potential applications in chiral photonics, spintronics, and optoelectronics. | Asad, Aqsa; Khaliq, Hafiz Saad; Kim, Min-Seok; Lee, Jae-Won; Kim, Hak-Rin | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | ; Kim, Hak-Rin/T-1897-2019; Khaliq, Hafiz Saad/ITW-2129-2023 | 58072931900; 56725698200; 59073001500; 58377059800; 7410124944 | rineey@knu.ac.kr; | MATERIALS ADVANCES | MATER ADV | 2633-5409 | 5 | 6 | ESCI | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 4.7 | 32.5 | 0.38 | 2025-05-07 | 2 | 2 | HALIDE PEROVSKITES; PHOTOLUMINESCENCE; ENHANCEMENT | Chirality; Laser beams; Magnetic anisotropy; Metamaterials; Perovskite; Photonic devices; Silicon photonics; Chiral metamaterials; Chiral photonics; Hydrogenated amorphous silicon (a-Si:H); Lead bromide; Low-loss; Metasurface; Multipolar resonances; Optical wavelength; Strong interaction; Wavelength of light; Dichroism | English | 2024 | 2024-03-18 | 10.1039/d3ma00953j | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Review | The role of lateral pelvic lymph node dissection in advanced rectal cancer: a review of current evidence and outcomes | Metastatic lateral pelvic lymph nodes (LPNs) in rectal cancer significantly impact the prognosis and treatment strategies. Western practices emphasize neoadjuvant chemoradiotherapy (CRT), whereas Eastern approaches often rely on LPN dissection (LPND). This review examines the evolving role of LPND in the context of modern treatments, including total neoadjuvant therapy (TNT), and the impact of CRT on the management of clinically suspicious LPNs. We comprehensively reviewed the key literature comparing the outcomes of LPND versus preoperative CRT for rectal cancer, focusing on recent advancements and ongoing debates. Key studies, including the JCOG0212 trial and recent multicenter trials, were analyzed to assess the efficacy of LPND, particularly in conjunction with preoperative CRT or TNT. Current evidence indicates that LPND can reduce local recurrence rates compared to total mesorectal excision alone in patients not receiving radiation therapy. However, the benefit of LPND in the context of neoadjuvant CRT is influenced by the size and pretreatment characteristics of LPNs. While CRT can effectively control smaller metastatic LPNs, larger or clinically suspicious LPNs may require LPND for optimal outcomes. Advances in surgical techniques, such as robotic-assisted LPND, offer potential benefits but also present challenges and complications. The role of TNT in controlling metastatic LPNs and improving patient outcomes is emerging but remains underexplored. The decision to perform LPND should be individualized based on patient-specific factors, including LPN size, response to neoadjuvant treatment, and surgeon expertise. Future research should focus on optimizing treatment protocols and further evaluating the role of TNT in managing metastatic LPNs. | Choi, Gyu-Seog; Kim, Hye Jin | Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Colorectal Canc Ctr, 807 Hoguk Ro, Daegu 41404, South Korea | 8058759100; 57204567554 | kyuschoi@knu.ac.kr; | ANNALS OF COLOPROCTOLOGY | ANN COLOPROCTOL | 2287-9714 | 2287-9722 | 40 | 4 | ESCI | GASTROENTEROLOGY & HEPATOLOGY;SURGERY | 2024 | 2.1 | 32.5 | 2.46 | 2025-05-07 | 5 | 5 | Lateral pelvic node dissection; Rectal neoplasms; Chemoradiation; Total neoadjuvant therapy; Local recurrence | TOTAL MESORECTAL EXCISION; PREOPERATIVE CHEMORADIOTHERAPY; NEOADJUVANT CHEMORADIOTHERAPY; METASTASIS; MULTICENTER; LYMPHADENECTOMY; SURGERY; RADIOTHERAPY; FEASIBILITY; RECURRENCE | Chemoradiation; Lateral pelvic node dissection; Local recurrence; Rectal neoplasms; Total neoadjuvant therapy | advanced cancer; cancer diagnosis; cancer patient; cancer prognosis; cancer radiotherapy; cancer recurrence; clinical outcome; diagnostic accuracy; follow up; human; lymph flow; lymph node dissection; lymph node metastasis; neoadjuvant chemoradiotherapy; neoadjuvant therapy; pelvis lymph node; positivity rate; prevalence; rectum cancer; recurrence risk; Review; robot assisted surgery; sensitivity and specificity; surgical technique; total mesorectal excision | English | 2024 | 2024-08 | 10.3393/ac.2024.00521.0074 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Alpha backgrounds in NaI(Tl) crystals of COSINE-100 | COSINE -100 is a dark matter direct detection experiment with 106 kg NaI(Tl) as the target material. 210Pb and daughter isotopes are a dominant background in the WIMP region of interest and are detected via ������ decay and a decay. Analysis of the a channel complements the background model as observed in the ������/������ channel. We present the measurement of the quenching factors and Monte Carlo simulation results and activity quantification of the a decay components of the COSINE -100 NaI(Tl) crystals. The data strongly indicate that the a decays probabilistically undergo two possible quenching factors but require further investigation. The fitted results are consistent with independent measurements and improve the overall understanding of the COSINE -100 backgrounds. Furthermore, the half-life of 216Po has been measured to be 143.4 +/- 1.2 ms, which is consistent with and more precise than most current measurements. | Adhikari, G.; Carlin, N.; Cavalcante, D. F.

| ○ | ○ | Article | Development of ultrathin 2D layered titanate Pt/K2Ti4O9/rGO nanocomposites for enhanced visible active photocatalytic detoxification of harmful organic pollutants | In this work, different wt% of rGO-loaded Pt-K2Ti4O9 (x = 2.5, 5, 7.5, 10, and 12.5 wt%) nanocomposites were prepared by a facile hydrothermal process and used for the degradation of two different dyes such as congo red (CR) methylene blue (MB) and tetracycline (TC) antibiotic solution under visible light illumination. The bare K2Ti4O9 (labeled as KTO) and the most active Pt-K2Ti4O9/5% rGO (labeled as Pt-KTO/5% rGO) composite catalysts were thoroughly characterized by XRD, FT-IR, Raman, XPS, FE-SEM with EDS, HR-TEM, UV-DRS, and PL analyses. The photocatalytic activity of Pt-KTO/5% rGO was remarkable compared to bare KTO and other rGO-supported catalysts. Pt-KTO/5% rGO composite photocatalyst showed enhanced photocatalytic degradation of 97%, 99%, & 99% for CR, MB & TC at 180, 120 and 180 min, respectively. Mineralization of dyes (TOC of 85%, 87%, and COD of 76%, 79% for CR, MB) and antibiotics (TOC of 78% and COD of 69% for TC) was confirmed by chemical oxygen demand (COD) and total organic carbon (TOC) measurements.

| ○ | ○ | Article | Facile synthesis of Co-doped In2O3 integrated with tubular g-C3N4 heterostructure and their synergistic effect on the enhanced photocatalytic degradation of tetracycline and oxygen evolution reaction | In this work, we developed cost-effective and environmentally friendly bifunctional catalysts for energy and environmental applications. Tubular graphitic carbon nitrides (TCN), In2O3, In2O3/TCN, and x% cobalt (Co) doped In2O3/TCN (x = 1 %, 3 %, and 5 wt% of Co) composite materials synthesized by polymerization and hydrothermal methods. The photocatalytic activity of these materials was tested for tetracycline (TC) removal under sunlight and visible light illumination. Among them, 5 % Co-In2O3/TCN composite exhibited the highest photocatalytic efficiency, achieving 100 % and 94 % TC degradation under sunlight and visible light, respectively. PL analysis indicated that the 5 % Co-In2O3/TCN composite exhibited superior charge separation efficiency. Scavenging tests confirmed that holes (h(+)) and superoxide radicals (O-2(center dot-)) play important roles in the photocatalytic process. The electrochemical performance of the prepared materials was investigated in 1.0 M KOH. Among the catalysts, the 5 % Co-In2O3/TCN@nickel foam (NF) composite showed the best oxygen evolution reaction (OER) performance with low overpotential (240 mV) and Tafel slope (95 mV/dec) and maintained stability for more than 24 h at 10 mA/cm(2). An electrolyzer using 5 % Co-In2O3/TCN@NF||Pt/C@NF catalyst achieved cell voltages of 1.73 V and 2.23 V at 10 mA/cm(2) and 100 mA/cm(2), respectively. In this study, we developed low-cost photo and electrocatalysts that exhibited excellent environmental remediation and energy production capabilities. | Kumaravel, Saranraj; Kumaravel, Sakthivel; Mukherjee, Arkadeep; Subash, B.; Periyasami, Govindasami; Chandramoorthy, Chandrasatheesh; Erusappan, Elangovan; Somu, Prathap; Ahn, Young-Ho; Liu, Chuan-Ming | Natl Taipei Univ Technol, Coll Elect Engn & Comp Sci, Taipei 10608, Taiwan; Saveetha Inst Med & Tech Sci SIMATS, Saveetha Sch Engn, Chennai 602105, Tamil Nadu, India; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Yeungnam Univ, Dept Civil Engn, Gyongsan 38541, South Korea; St Josephs Coll Engn, Dept Chem, OMR, Chennai 600119, Tamil Nadu, India; King Saud Univ, Coll Sci, Dept Chem, POB 2455, Riyadh 11451, Saudi Arabia; Seoul Natl Univ Sci & Technol, Dept Environm Engn, Seoul 01811, South Korea; Manipal Univ Jaipur, Sch Civil Biotechnol & Chem Engn, Dept Biotechnol & Chem Engn, Jaipur 303007, India; Natl Taipei Univ Technol, Dept Comp Sci & Informat Engn, Taipei, Taiwan | ; Erusappan, Elangovan/GON-8284-2022; Somu, Prathap/AAC-6584-2020; KUMARAVEL, SAKTHIVEL/KBC-0974-2024; Mukherjee, Arkadeep/JMC-0189-2023; Subash, B./AAH-7295-2020; SOMU, PRATHAP/AAC-6584-2020; Chandramoorthy, Chandrasatheesh/JAA-9487-2023; Govindasami, Periyasami/K-9962-2016 | 57189380978; 57212580936; 58453084200; 57210975646; 15059331100; 56137108100; 57195219856; 57202019969; 24586951200; 8202608200 | sakthivel@knu.ac.kr;prathaps1987@gmail.com;yhahn@ynu.ac.kr;cmliu@ntut.edu.tw; | COLLOIDS AND SURFACES A-PHYSICOCHEMICAL AND ENGINEERING ASPECTS | COLLOID SURFACE A | 0927-7757 | 1873-4359 | 703 | SCIE | CHEMISTRY, PHYSICAL | 2024 | 5.4 | 32.7 | 0 | 2025-05-07 | 0 | 2 | Photodegradation; Co-In2O3/TCN; Visible light; Solar light; Tetracycline; Oxygen evolution reaction | PERFORMANCE; ENERGY; CO3O4 | Co-In<sub>2</sub>O<sub>3</sub>/TCN; Oxygen evolution reaction; Photodegradation; Solar light; Tetracycline; Visible light | Bioremediation; Graphitic Carbon Nitride; Laser beams; Photocatalytic activity; Photodegradation; Photolysis; Rate constants; alcohol; carbon; cobalt; indium; nitrogen; oxygen; superoxide; tetracycline; water; Cobalt-in2O3/tubular graphitic carbon nitride; Evolution reactions; Graphitic carbon nitrides; Oxygen evolution; Photo degradation; Solar light; Tetracycline; Tubulars; Visible light; ]+ catalyst; Article; decomposition; degradation; detoxification; ecosystem restoration; electron; electron transport; energy yield; field emission scanning electron microscopy; Fourier transform infrared spectroscopy; illumination; impedance spectroscopy; light; oxygen evolution reaction; photocatalysis; photodegradation; photoluminescence; pore volume; renewable energy; separation technique; sunlight; synergistic effect; transmission electron microscopy; X ray photoemission spectroscopy; Potassium hydroxide | English | 2024 | 2024-11-20 | 10.1016/j.colsurfa.2024.135340 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Graphitic carbon nitride sheets sandwiched metal oxides: A novel platform for S-Scheme heterojunction generation for efficient photodegradation of volatile organics | This study reports the preparation of new kind of S-Scheme heterojunction (SSHJ) photocatalyst by distributing two semiconducting metal oxides (titanium dioxide and ZnO) onto the surface of graphitic carbon nitride (G-CN) two dimensional (2D) sheets. The composite photocatalysts, designated as T/Z@ GCN SSHJ, were prepared with different mass ratios of T,Z and G-CN.X-ray diffraction (XRD) analysis, transmission electron microscopy (TEM), field emission scanning electron microscopy, X-ray photoelectron spectroscopy (XPS), UV-Vis diffuse reflectance spectroscopy (DRS), photoluminescence (PL) spectroscopy were used to characterize the microstructure, morphology, chemical composition, electronic states, and optical properties of the T/Z@ GCN SSHJ composite. TEM image of the typical T/Z@ GCN SSHJ composite shows the presence of distribution of particles with sizes in the range 40-80 nm on the lamellar surface of G-CN inferring the formation of a heterostructure Z(0 D) /G-CN(2D)/T(0D) SSHJ composite. The comparison of the core level XPS spectrum of Ti 2p, Zn 2p, C1s, O1s and N1s of T/Z@ GCNSSHJ composite with the binary composites (T+G-CN and Z+G-CN) and pristine components clearly suggests that that Z, T and G-CN are kept together through van der Walls interactions. The T/Z@ GCN SSHJ composite photocatalyst with T: Z: G-CN mass ratio of 1.0: 0.80: 0.12 exhibited enhanced photocatalytic degradation (%) over binary and pristine single components for all the tested volatile organic compounds (VOCs), namely, acetaldehyde (ACD), ethyl acetate (EA), toluene (T) and benzaldehyde (BA). On comparing the % removal of VOCs after 20 minute of light irradiation, BA showed the highest removal % (94.3 %) and the others take the following order: ACD (70.9 %) >EA (56.45 %)> TL (40.12 %). The study explains the enhanced performance of T/Z@ G-CN HJ composite towards VOC photodegradation in terms of S-Scheme based charge transfer and internal electric field driven efficient charge separation. The charge transfer process of T/Z@ GCN HJ composite photocatalysts is discussed through S-Scheme HJ formation and supported with electronic states and band energy levels of the constituent components derived through the results of XPS and DRS analysis. This study gives insight into the design for regulating the hetero-interfaces for enhancing the photocatalysis and expected to further understand into charge transfer mechanism at multi-junction-based photocatalysts. | Nandakumar, Velu; Arumugam, Chandravadhana; Karthikeyan, Vaithinathan; Roy, Vellaisamy A.

| ○ | ○ | Article | Influence of nanoprecipitation techniques on lignin nanoparticle structure | Lignin nanoparticles (LNPs) have garnered significant interest as sustainable and bioactive materials, finding promising applications across diverse fields. In this study, we synthesized LNPs using four nanoprecipitation methods: dialysis, evaporation, dilution, and acidic dilution. Our investigation delved into how these methods affect LNP morphology and properties. Results unequivocally demonstrate the profound impact of the chosen nanoprecipitation method on LNP characteristics. Dialysis and dilution methods yielded LNPs distinguished by their pronounced hollowness, with an average diameter of 330 nm and 430 nm, whereas the evaporation and acidic dilution methods resulted in less hollow structures with average diameter of 270 nm and 800 nm. The duration of unstable conditions during synthesis significantly influenced particle aggregation, giving rise to a broad size distribution. Furthermore, our prepared LNPs showcased exceptional antioxidant activity (>80 % radical scavenging activity at 0.05 mg/mL of LNPs) and potent antibacterial efficacy against gram-positive bacteria Staphylococcus aureus. This study not only offers crucial insights into optimizing LNP synthesis but also elucidates the nexus between different nanoprecipitation methods and resulting morphology and functionality. The findings provide a fundamental framework for tailoring LNP properties to specific applications, advancing sustainable and eco-friendly technologies within the biomedical, nanotechnology, and materials science domains. | Kim, Gyuhwan; Park, Jaehyeon; Kim, Bo Min; Kim, Jinho; Kim, Kang-Jae; Park, Jaehyeung | Kyungpook Natl Univ, Dept Biofibers & Biomat Sci, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Carbon & Fiber Composite Mat, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Wood Sci & Technol, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Forestry Sci & Landscape Architecture, Major Wood Sci & Technol, Daegu 41566, South Korea | ; Kim, Kang-Jae/K-3915-2019 | 58745378700; 58745582800; 58641148700; 56813308400; 35733947500; 55566554000 | parkj@knu.ac.kr;jaeya0624@knu.ac.kr; | COLLOIDS AND SURFACES A-PHYSICOCHEMICAL AND ENGINEERING ASPECTS | COLLOID SURFACE A | 0927-7757 | 1873-4359 | 682 | SCIE | CHEMISTRY, PHYSICAL | 2024 | 5.4 | 32.7 | 3.29 | 2025-05-07 | 10 | 11 | Lignin nanoparticle; Nanoprecipitation; Morphology; Antioxidant; Antibacterial | ANTIMICROBIAL ACTIVITY; FORMATION MECHANISM; SIZE; ANTIOXIDANTS; NANOSPHERES; FABRICATION | Antibacterial; Antioxidant; Lignin nanoparticle; Morphology; Nanoprecipitation | Agglomeration; Antioxidants; Bacteria; Dialysis; Dilution; Evaporation; Agglomeration; Antioxidants; Bacteria; Dialysis; Dilution; Evaporation; Lignin; Morphology; lignin; nanoparticle; Antibacterials; Average diameter; Bioactive material; Dilution method; Lignin nanoparticle; Nano precipitations; Nanoparticle properties; Nanoparticle structures; Nanoprecipitation method; Sustainable materials; antibacterial activity; antioxidant activity; Article; chemical structure; controlled study; dialysis; dilution; evaporation; morphology; nonhuman; precipitation; Staphylococcus aureus; synthesis; Nanoparticles | English | 2024 | 2024-02-05 | 10.1016/j.colsurfa.2023.132803 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Risk tolerance towards research and development investment: the role of firm size and technology intensity | This research examines how risk tolerance towards research and development (R&D) investment varies by firm size and technology intensity using a case study of four groups of manufacturing firms (i.e. large high-tech firms, small high-tech firms, large low-tech firms, and small low-tech firms) in South Korea. Our research contributes to the literature by offering the first empirical application quantifying different risk tolerances towards R&D investment of firms of varying sizes and technology intensities using total factor productivity and optimal portfolio frontiers. We find that the risk tolerance towards R&D investment is proportional to firm size, and high-tech firms tend to be more risk tolerant than low-tech firms given the same firm size. Furthermore, we find that large low-tech firms have a greater tolerance for risk than small high-tech firms when the present guaranteed return is lower, but risk tolerance is reversed as the current guaranteed return increases. These findings could be used to inform R&D project funding decisions in particular, our finding of higher risk tolerance of small high-tech firms with higher present guaranteed return suggests that government subsidies for R&D investment may function as the present guaranteed return for small high-tech businesses. © 2024 Informa UK Limited, trading as Taylor & Francis Group. | Cho, Seong-Hoon; Kang, Nawon; Lee, Jaimin | Department of Agricultural and Resource Economics, University of Tennessee, Knoxville, TN, United States; Department of Agricultural Economics, Texas A & M University, College Station, TX, United States; Department of International Economics and Trade, Kyungpook National University, Daegu, South Korea | 22940061400; 57846455500; 56106356700 | jm064@knu.ac.kr; | Applied Economics | APPL ECON | 0003-6846 | 1466-4283 | SSCI | ECONOMICS | 2024 | 2.1 | 32.7 | 0 | 2025-05-07 | 0 | firm size; R&D investment; risk tolerance; technology; total factor productivity | English | Article in press | 2024 | 10.1080/00036846.2024.2384671 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | The cosmic ray energetics and mass for the international space station (ISS-CREAM) instrument | The ISS-CREAM instrument is the modified version of the Cosmic Ray Energetics And Mass (CREAM) experiment, which was flown on balloons multiple times over Antarctica and later installed on the International Space Station (ISS). Its primary objective is to measure the energy spectra of individual cosmic-ray elements for the charge range of Z = 1 to Z = 26, in the energy range of similar to 10(12) to similar to 10(15) eV. The instrument comprises a tungsten/ scintillator calorimeter and a pixelated silicon charge detector as primary detectors to determine the energy and charge of cosmic rays. Additionally, it includes top and bottom scintillator counting detectors and a boronated scintillator detector to differentiate between electrons and hadrons for multi-TeV electron measurements. The ISS-CREAM instrument was installed on the ISS in August 2017 and operated until February 2019. This paper provides an overview of the instrument, focusing on its detectors, trigger systems, common electronics, and power systems. The paper highlights the modifications made to these components to optimize their performance for ISS operations. | Yoon, Y. S.; Amare, Y.; Angelaszek, D.; Anthony, N.; Cheryian, K.; Choi, G.

| ○ | Article | Adhesion and volume filling in one-dimensional population dynamics under Dirichlet boundary condition | We generalize the one-dimensional population model of Anguige & Schmeiser [1] reflecting the cell-to-cell adhesion and volume filling and classify the resulting equation into the six types. Among these types, we fix one that yields a class of advection-diffusion equations of forward-backward-forward type and prove the existence of infinitely many global-in-time weak solutions to the initial-Dirichlet boundary value problem when the maximum value of an initial population density exceeds a certain threshold. Such solutions are extracted from the method of convex integration by Müller & Šverák [12]; they exhibit fine-scale density mixtures over a finite time interval, then become smooth and identical, and decay exponentially and uniformly to zero as time approaches infinity.

| ○ | ○ | Article | Eligibility and Cost-Utility Analysis of Dapagliflozin in Patients with Heart Failure Across the Whole Spectrum of Ejection Fraction in South Korea | Background The DAPA-HF and DELIVER trials demonstrated the clinical benefits of dapagliflozin in heart failure (HF) patients across the entire ejection fraction (EF) spectrum. However, further investigation is needed for the real-world application of dapagliflozin in HF patients. This study examines the proportion of real-world HF patients eligible for dapagliflozin and evaluates the cost-effectiveness of adding dapagliflozin to current HF therapy. Methods Data from the nationwide prospective registry, the Korean Acute Heart Failure (KorAHF) registry, were used to determine dapagliflozin eligibility based on the enrollment criteria of the DAPA-HF/DELIVER trials. A cost-utility analysis was conducted using a Markov model to assess the cost-effectiveness of dapagliflozin by comparing it to the standard of care. Results Out of 5178 KorAHF patients, 48.7% met the enrollment criteria of the DAPA-HF/DELIVER trials, while 89.5% met the label criteria (US Food and Drug Administration, European Medicines Agency, and Korean Ministry of Food and Drug Safety). Eligibility was highest among HF patients with preserved EF (55.3% vs. HF with mildly reduced EF and HF with reduced EF 46.4%). Dapagliflozin proved to be cost-effective, with an incremental cost-effectiveness ratio (ICER) of 4557 US dollar (US$) per quality-adjusted life year, which falls below the US$18,182 willingness-to-pay threshold. The cost-effectiveness benefit was more pronounced in patients with a left ventricular EF (LVEF) 40%). Conclusions Discrepancies in dapagliflozin eligibility were observed between real-world data and clinical trial results. The addition of dapagliflozin to HF therapy proved to be highly cost-effective across the entire EF spectrum. | Kim, Eui-Soon; Park, Sun-Kyeong; Cho, Daniel Sung-ho; Youn, Jong-Chan; Lee, Hye Sun; Lee, Hae-Young; Cho, Hyun-Jai; Choi, Jin-Oh; Jeon, Eun-Seok; Lee, Sang Eun; Kim, Min-Seok; Kim, Jae-Joong; Hwang, Kyung-Kuk; Cho, Myeong-Chan; Chae, Shung Chull; Kang, Seok-Min; Park, Jin Joo; Choi, Dong-Ju; Yoo, Byung-Su; Cho, Jae Yeong; Kim, Kye Hun; Oh, Byung-Hee; Greenberg, Barry; Baek, Sang Hong | Korea Adv Inst Sci & Technol KAIST, Grad Sch Med Sci & Engn, Daejeon, South Korea; Catholic Univ Korea, Coll Pharm, Bucheon, South Korea; Catholic Univ Korea, Seoul St Marys Hosp, Catholic Res Inst Intractable Cardiovasc Dis, Coll Med,Div Cardiol,Dept Internal Med, 222 Banpo Daero, Seoul 06591, South Korea; Yonsei Univ, Coll Med, Biostat Collaborat Unit, Seoul, South Korea; Seoul Natl Univ Hosp, Dept Internal Med, Seoul, South Korea; Seoul Natl Univ, Sch Med, Seoul, South Korea; Sungkyunkwan Univ, Coll Med, Dept Internal Med, Seoul, South Korea; Univ Ulsan, Coll Med, Asan Med Ctr, Dept Internal Med, Seoul, South Korea; Chungbuk Natl Univ Hosp, Dept Internal Med, Cheongju, South Korea; Kyungpook Natl Univ, Coll Med, Dept Internal Med, Daegu, South Korea; Yonsei Univ, Coll Med, Dept Internal Med, Seoul, South Korea; Seoul Natl Univ, Bundang Hosp, Dept Internal Med, Seongnam, South Korea; Yonsei Univ, Wonju Coll Med, Dept Internal Med, Wonju, South Korea; Chonnam Natl Univ, Med Sch, Dept Cardiovasc Med, Gwangju, South Korea; Incheon Sejong Hosp, Dept Cardiovasc Med, Incheon, South Korea; UC San Diego Hlth Syst, Dept Cardiol, La Jolla, CA USA | Cho, Jae Yeong/GVT-2986-2022; Oh, Byung-Hee/G-9875-2011; Youn, Jong-Chan/AAS-1405-2020; Lee, Hye Sun/J-2154-2015; choi, jo/O-5940-2014; Choi, Dong-Ju/J-5686-2012; Jeong, Gi/AAB-2830-2021; LEE, JI/L-6920-2013; Lee, Hye/J-2154-2015; Kim, Soo-Yeon/ADR-9663-2022; CHO, SUNGHWAN/HGE-0864-2022 | 57220956934; 56010737100; 58353239600; 14070921900; 57208650357; 56151235500; 35285421400; 15848011800; 7004279641; 57207065107; 57212315719; 57225030259; 58842870300; 58092080500; 7101962036; 7405685375; 35799900000; 35274349200; 7102851884; 23024350000; 56150430800; 57216293873; 7201629440; 7201371594 | jong.chan.youn@gmail.com; | AMERICAN JOURNAL OF CARDIOVASCULAR DRUGS | AM J CARDIOVASC DRUG | 1175-3277 | 1179-187X | 24 | 2 | SCIE | CARDIAC & CARDIOVASCULAR SYSTEMS;PHARMACOLOGY & PHARMACY | 2024 | 3 | 32.8 | 0.69 | 2025-05-07 | 2 | 2 | ASSOCIATION; COMMITTEE | Benzhydryl Compounds; Cost-Benefit Analysis; Glucosides; Heart Failure; Humans; Republic of Korea; Stroke Volume; angiotensin receptor antagonist; beta adrenergic receptor blocking agent; dapagliflozin; dipeptidyl carboxypeptidase inhibitor; mineralocorticoid antagonist; benzhydryl derivative; dapagliflozin; glucoside; aged; Article; cohort analysis; cost effectiveness analysis; cost utility analysis; eligibility; female; heart ejection fraction; heart failure with preserved ejection fraction; heart failure with reduced ejection fraction; heart left ventricle ejection fraction; human; major clinical study; male; Markov chain; patient registry; quality adjusted life year; South Korea; Willingness To Pay; cost benefit analysis; heart failure; heart stroke volume | English | 2024 | 2024-03 | 10.1007/s40256-024-00632-w | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

If (M, g) is a (2n+1)-dimensional Kenmotsu manifold and g represents an almost Ricci-Bourguignon soliton, then we find a sufficient condition under which the manifold M is Einstein (trivial). Next, we show that if g is an almost Ricci-Bourguignon soliton on M and the Reeb vector field 4 leaves lambda + pr invariant, then g reduces to Ricci-Bourguignon soliton on M. Finally, we prove that if g is a gradient almost Ricci-Bourguignon soliton, then the manifold M is either Einstein or g is a gradient n-Yamabe soliton on M. As a consequence of the results, we obtain several corollaries. | Prakasha, D. G.; Amruthalakshmi, M.
