| ○ | ○ | Article | Pathways toward zero-emission textile industry by 2050: A case study of Albania | The growing energy demand in the textile and leather sub-branch presents a crucial opportunity to integrate sustainable solutions. By leveraging renewable energy systems (RES), enhancing efficiency measures, and adopting advanced technologies, the sector can address escalating energy needs while minimizing environmental impact and optimizing cost. Aligning these efforts with the National Energy and Climate Plan (NECP) and Sustainable Development Goals (SDGs) objectives strengthens supply resilience. It accelerates the transition toward a zero-emission society through sophisticated modeling tools. At the core of this research is the seamless integration of RETScreen Expert, a globally recognized tool for clean energy management, and the Low Emissions Analysis Platform (LEAP), an advanced system for energy optimization, scenario analysis, and addressing supply challenges enabling to establish a cohesive framework, effectively balancing energy demand management with bold decarbonization strategies. Artificial Intelligence (AI) further amplifies this approach, employing supervised Machine Learning (ML) techniques as AI's subset, particularly Multi Linear Regression (MLR), to forecast longterm activity levels trained on GDP and population dynamics labeled data leading to a near-perfect coefficient of determination (R2) of the association of 0.99. Simulation results highlight substantial advancements at the factory level, with annual specific energy consumption decreasing from 1255 kWh per employee to -341 kWh, effectively transforming the facility into a Positive Energy Factory (PEF). LEAP utilizes historical energy data (2005-2022), categorized by fuel type and activity level data, to generate detailed and precise projections.

| ○ | ○ | Article | Design of a Lifting Robot for Repetitive Inter-Floor Material Transport with Adjustable Gravity Compensation | The construction of high-rise buildings necessitates efficient and reliable material transport systems to improve productivity and reduce labor-intensive tasks. Traditional methods such as cranes and elevators are widely used but are often constrained by high costs and spatial limitations. Manipulator-based robotic systems have been explored as alternatives; however, they require complex control algorithms and struggle with confined construction environments. To address these challenges, we propose a lifting robot designed for repetitive inter-floor material transport in construction sites. The proposed system integrates a gear-connected double parallelogram linkage with a crank-rocker mechanism, enabling one-degree of freedom (1-DOF) operation for simplified control and precise positioning. Additionally, a spring-cable-based gravity compensation mechanism is implemented to reduce actuator torque, enhancing energy efficiency and structural stability. A prototype was fabricated, and experimental validation was conducted to evaluate torque reduction, positioning accuracy, and structural performance. Results demonstrate that the proposed system effectively minimizes driving torque, improves load-handling stability, and enhances overall operational efficiency. This study provides a foundation for developing automated lifting solutions in construction, contributing to reduced worker strain and increased productivity. | Kwak, Byungseo; Lim, Seungbum; Suh, Jungwook | Kyungpook Natl Univ, Dept Robot & Smart Syst Engn, Daegu 41566, South Korea | 59486895200; 58627825200; 36606826500 | qudtj0216@knu.ac.kr; tmdqjas2@knu.ac.kr; jwsuh@knu.ac.kr; | ROBOTICS | ROBOTICS | 2218-6581 | 14 | 6 | ESCI | ROBOTICS | 2024 | 3.3 | 42.7 | 0 | 0 | lifting robot; material transport; gravity compensation; construction automation; mechanical design | construction automation; gravity compensation; lifting robot; material transport; mechanical design | English | 2025 | 2025-05-26 | 10.3390/robotics14060069 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||||
| ○ | ○ | Article | How to Coordinate Urban Ecological Networks and Street Green Space Construction? Insights from a Multi-Scale Perspective | Rapid socio-economic development and imbalanced ecosystem conservation have heightened the risk of species extinction, reduced urban climate adaptability, and threatened human health and well-being. Constructing ecological green space networks is an effective strategy for maintaining urban ecological security. However, most studies have primarily addressed biodiversity needs, with limited focus on coordinating street spaces in human settlement planning. This study examines the area within Chengdu's Third Ring Road, employing the following methodologies: (1) constructing the regional ecological network using Morphological Spatial Pattern Analysis (MSPA), the Integrated Valuation of Ecosystem Services and Trade-offs (InVEST) model, and circuit theory; (2) analyzing the street green view index (GVI) through machine learning semantic segmentation techniques; and (3) identifying key areas for the coordinated development of urban ecological networks and street green spaces using bivariate spatial correlation analysis. The results showed that (1) Chengdu's Third Ring Road exhibits high ecological landscape fragmentation, with 41 key ecological sources and 94 corridors identified. Ecological pinch points were located near urban rivers and surrounding woodlands, while ecological barrier points were concentrated in areas with dense buildings and complex transportation networks. (2) Higher street GVI values were observed around university campuses, urban parks, and river-adjacent streets, while lower GVI values were found near commercial areas and transportation hubs. (3) To coordinate the construction of ecological networks and street green spaces, the central area of the First Ring Road and the northwestern region of the Second and Third Ring Roads were identified as priority restoration areas, while the northern, western, and southeastern areas of the Second and Third Ring Roads were designated as priority protection areas. This study adopts a multi-scale spatial perspective to identify priority areas for protection and restoration, aiming to coordinate the construction of urban ecological networks and street green spaces and provide new insights for advancing ecological civilization in high-density urban areas. | Hou, Shujun; Yu, Ying; Jung, Taeyeol; Han, Xin | Kyungpook Natl Univ, Dept Landscape Architecture, Daegu 41566, South Korea; Shandong Agr Univ, Dept Landscape Architecture, Tai An 271018, Peoples R China; Zhejiang A&F Univ, Coll Landscape Architecture, Hangzhou 311300, Peoples R China | 59524885200; 58742619600; 55490551100; 57716224500 | jungty@knu.ac.kr; hanxin@zafu.edu.cn; | LAND | LAND-BASEL | 2073-445X | 14 | 1 | SSCI | ENVIRONMENTAL STUDIES | 2024 | 3.2 | 42.7 | 0 | 2025-05-07 | 0 | 0 | ecological networks; MSPA; circuit theory; street view images; green view index; bivariate spatial autocorrelation | ECOSYSTEM SERVICES; HABITAT PATCHES; CITY; INFRASTRUCTURE; OPTIMIZATION; CONSERVATION; BIODIVERSITY; MANAGEMENT; STABILITY | bivariate spatial autocorrelation; circuit theory; ecological networks; green view index; MSPA; street view images | Chengdu; China; Sichuan; autocorrelation; greenspace; machine learning; spatial analysis; urban area | English | 2025 | 2025-01 | 10.3390/land14010026 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Review | Extracellular vesicle-derived MicroRNAs as potential therapies for spinal cord and peripheral nerve injuries | Complete nerve regeneration is limited in current therapeutic approaches for spinal cord injuries (SCIs) and peripheral nerve injuries (PNIs). Extracellular vesicles (EVs) and microRNAs (miRNAs) play a pivotal role in intercellular communication by transporting various biomolecules, including miRNAs, to the recipient cells. Thus, they are promising targets for novel neural regeneration drugs. This comprehensive study examined the roles of EV-derived miRNAs in facilitating neural rejuvenation after SCI and PNI. It also explored the mechanisms by which they augment neuroprotection and promote cell viability. It also discusses their translational potential for treating nerve injury and evaluates their potential impact on advancements in nerve resurrection and prospective research in regenerative medicine. The findings may provide effective treatments and improve outcomes, as well as contribute to addressing the direction for the next studies, for the pathologies of SCI and PNI. | Lim, Young-Ju; Seo, Min-Soo; Park, Wook-Tae; Park, Sangbum; Lee, Gun Woo | Yeungnam Univ, Coll Med, Dept Orthoped Surg, Daegu, South Korea; Kyungpook Natl Univ, Coll Vet Med, Dept Vet Tissue Engn, Daegu, South Korea; Michigan State Univ, Coll Human Med, Dept Med Pharmacol & Toxicol, East Lansing, MI, USA; Michigan State Univ, Inst Quantitat Hlth Sci & Engn IQ, East Lansing, MI, USA; Yeungnam Univ, Coll Med, Med Ctr, Dept Orthoped Surg, 170 Hyonchung Ro, Daegu 42415, South Korea | 57220206982; 35254332100; 57216658028; 55390841500; 59660308500 | gwlee1871@gmail.com; | RNA BIOLOGY | RNA BIOL | 1547-6286 | 1555-8584 | 22 | 1 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY | 2024 | 3.4 | 42.8 | 0 | 2025-06-11 | 0 | 0 | Spinal cord injury; peripheral nerve injury; extracellular vesicles; microRNAs; neural regeneration; therapeutic implications | AXONAL REGENERATION; NEURITE OUTGROWTH; ISCHEMIC-STROKE; EXPRESSION; BIOMARKERS; P27(KIP1); RECOVERY; NEURONS; PATHWAY; GROWTH | extracellular vesicles; microRNAs; neural regeneration; peripheral nerve injury; Spinal cord injury; therapeutic implications | Animals; Extracellular Vesicles; Humans; MicroRNAs; Nerve Regeneration; Peripheral Nerve Injuries; Spinal Cord Injuries; microRNA; microRNA; cell viability; exosome; human; nerve injury; nerve regeneration; neuroprotection; peripheral nerve injury; pharmaceutics; regenerative medicine; rejuvenation; review; spinal cord; spinal cord injury; therapy; animal; genetics; metabolism; nerve regeneration | English | 2025 | 2025-12-31 | 10.1080/15476286.2025.2512618 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Impact of open femoral endarterectomy on treating multilevel iliac and common femoral artery occlusive disease | Purpose This study aimed to evaluate the impact of femoral endarterectomy (FE) on treating multilevel iliac and common femoral artery occlusive disease.Materials and methods From January 2013 to December 2022, 106 limbs in 103 patients with multilevel arterial occlusive disease underwent open FE and iliac angioplasty (FEIA) with or without infrainguinal revascularization. The primary outcome assessment was the changes in the TransAtlantic Inter-Society Consensus (TASC) II classification during the operation; the secondary outcomes included the primary patency (PP) and secondary patency (SP) of FEIA. The risk factors for PP loss were evaluated.Results Of the 103 patients, 91 were male. A total of 56 limbs were treated for chronic limb-threatening ischemia, and 61 limbs underwent infrainguinal revascularization. Preoperatively, aortoiliac occlusive disease (AIOD) was classified as TASC II C in 65 (61%) limbs and D in 41 limbs. During the operation, 19 limbs received additional thrombectomy for subacute or chronic thrombus components. Overall, FE and additional thrombectomy reduced the TASC II classification of AIOD from complex lesions (TASC II C/D) to simple lesions (B or lesser) in 101 (95%) of 106 limbs. Three early mortalities (2.8%, two from acute myocardial infarctions and one from pneumonia) were recorded. The PP and SP of FEIA were 89% and 96% at 1 year, 80% and 94% at 3 years, and 77% and 94% at 5 years, respectively. The severity of iliac and common femoral artery disease was not associated with PP loss of FEIA.Conclusions Despite the challenging nature of initially classified TASC II C/D lesions, our findings highlight the effectiveness of FE in reducing TASC II classification and the durable patency achieved with FEIA. Hybrid FEIA could be a viable primary treatment option, particularly for lesions featuring severe iliac and common femoral artery disease. | Park, Suehyun; Ku, Taewan; Hwang, Deokbi; Yun, Woo-Sung; Huh, Seung; Kim, Hyung-Kee | Kyungpook Natl Univ Hosp, Dept Surg, Div Vasc & Endovasc Surg, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Surg,Div Vasc & Endovasc Surg, Daegu, South Korea | Kim, Hyung-Kee/JBR-8125-2023 | 58081703400; 58081357900; 57194422879; 35070717000; 7101832929; 35169819900 | hkkim6260@knu.ac.kr; | FRONTIERS IN SURGERY | FRONT SURG | 2296-875X | 12 | SCIE | SURGERY | 2024 | 1.8 | 42.8 | 0 | 2025-05-07 | 0 | 0 | peripheral arterial disease; ischemia; treatment outcome; endarterectomy; stent; common femoral artery | ENDOVASCULAR TREATMENT; VASCULAR-SURGERY; OPEN REPAIR; SOCIETY; HYBRID; RECONSTRUCTION; GUIDELINES; MANAGEMENT; STANDARDS | common femoral artery; endarterectomy; ischemia; peripheral arterial disease; stent; treatment outcome | English | 2025 | 2025-01-21 | 10.3389/fsurg.2025.1445846 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Examining the Potential of CuO/ZnBi2O4 Heterojunction Photocathode in the Photoelectrochemical Water-Splitting Applications | The primary objective of this study is to synthesize and examine a highly efficient photo-catalyst endowed with robust and sustained photo-catalytic capabilities, with a particular focus on its applicability within photoelectrochemical (PEC) processes. The methodology employed involves the hydrothermal synthesis of CuO, subsequently subjected to a spin-coating process for the deposition of ZnBi2O4 (ZBO) across a multi-layer, followed by high-temperature annealing for structure optimization. A comprehensive suite of analyses encompassing morphological, structural, textual, optical, and PEC measurements was conducted on the synthesized samples. Experimental findings underscore the notable enhancement in photo-catalytic performance achieved through the formation of heterojunction, particularly conductive to facilitating the PEC hydrogen evolution reaction (HER) process when juxtaposed with the individual constituents (CuO and ZBO). Among these samples, CuO/ZBO-10 exhibited commendable photo-stability and demonstrated remarkable visible-light-induced photo-catalytic efficiency in driving the PEC HER process. The integration of ZBO coatings notably augments the PEC performance of CuO, with the CuO/ZBO-10 photocathode attaining a photo-current density of up to -1.35 mA.cm(-2) at 0 V vs. RHE, under standard test conditions. Importantly, the CuO/ZBO-10 photocathode exhibits superior retention of optical activity, with 63.11% maintained after 3600 s of irradiation, significantly surpassing the performance of bare CuO (10.98%). A detailed examination of the experimental data elucidates that the observed enhancements in photo-current density and stability can be attributed to the facilitated electrochemical charge transfer at the electrode/electrolyte interface and the concomitant mitigation of photo-corrosion rates. | Nguyen, Hoang Lam; Truong, Nguyen Tam Nguyen; Sang-June, Kwon; Tamboli, Mohaseen S.; Shaikh, Hamid; Poulose, Anesh Manjaly; Kang, Seung Beom; Chung, Dong Chul; Kim, Chang-Duk; Jung, Jae Hak | Yeungnam Univ, Sch Chem Engn, 280 Daehak Ro, Gyeongbuk 38541, Gyeongsan, South Korea; Korea Inst Energy Technol KENTECH, 21 KENTECH Gil, Naju 58330, Jeonnam, South Korea; King Saud Univ, SABIC Polymer Res Ctr, Dept Chem Engn, POB 800, Riyadh 11421, Saudi Arabia; Korea Carbon Ind Promot Agcy, Res & Dev Ctr, 110-11 Banryong Ro, Jeonju 54853, South Korea; Jeonbuk Natl Univ, Carbon Fiber Convergence Technol Res Ctr, 567 Baekjedaero, Jeonju 54896, South Korea; Kyungpook Natl Univ, Dept Phys, 80 Daehakro, Bukgu 41566, Daegu, South Korea | Truong, Nguyen/KPB-0969-2024; Lam, Nguyen/KRO-9111-2024; Shaikh, Hamid/ABD-2221-2020 | 58313026700; 25958384000; 59155220900; 6506784566; 55919054400; 57003694700; 58032913000; 7401719367; 57200982445; 13308234300 | nhlam@tvu.edu.vn; jhjung@ynu.ac.kr; | KOREAN JOURNAL OF CHEMICAL ENGINEERING | KOREAN J CHEM ENG | 0256-1115 | 1975-7220 | 42 | 2 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, CHEMICAL | 2024 | 3.2 | 42.9 | 0 | 2025-05-07 | 1 | 1 | Coating layers; CuO; Photoelectrochemical; Photo-stability; ZnBi2O4 | CUO THIN-FILMS; ENHANCED PHOTOCATALYTIC ACTIVITY; P-N HETEROJUNCTION; CHARGE-TRANSFER; PERFORMANCE; PHOTOACTIVITY; PHOTOANODES; DECORATION; REDUCTION | Coating layers; CuO; Photo-stability; Photoelectrochemical; ZnBi<sub>2</sub>O<sub>4</sub> | Corrosion rate; Deposition rates; Electrolytes; Hard facing; Photocatalytic activity; Photocathodes; Photochemical forming; Spin coating; Zinc coatings; 'current; Coating layer; Hydrogen evolution reactions; Photo-catalytic; Photo-stability; Photoelectrochemical hydrogen; Photoelectrochemical water splitting; Photoelectrochemicals; Primary objective; Reaction process; Hydrothermal synthesis | English | 2025 | 2025-02 | 10.1007/s11814-024-00353-5 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Experimental investigation on metakaolin/coal fly ash-based porous geopolymer grouting material for geotechnical applications | This research investigates the development of a porous geopolymer cement grout for soil grouting applications, aiming to reduce carbon emissions associated with Portland cement while maintaining critical performance characteristics such as strength and permeability. Class F fly ash and metakaolin were used as aluminosilicate precursors, activated by sodium silicate and sodium hydroxide solutions. The addition of hydrogen peroxide served as a foaming agent to introduce porosity. Compressive strength and porosity were evaluated, with results showing that metakaolin significantly increased compressive strength due to its smaller particle size and higher reactivity. A higher molarity of sodium silicate enhanced strength by reducing the water-to-solid ratio, creating a denser matrix. In contrast, increasing hydrogen peroxide content raised porosity but reduced compressive strength by generating gas bubbles. X-ray diffraction (XRD) analysis revealed the ongoing formation of hydration products and a growing amorphous structure in the geopolymer matrix, contributing to strength development over time. The study concludes that the geopolymer grout can be optimized for a wide range of soil stabilization applications by adjusting material composition, foaming agent concentration, and activator molarity, offering an environmentally sustainable alternative to traditional cement grouts. | Sierra, Karla; Park, Philip; Cheng, Chu-Lin; Kim, Yong Je; Hwang, Jae-Hoon; Kim, Bubryur; Nam, Boo Hyun; An, Jinwoo | Univ Texas Rio Grande Valley, Dept Civil Engn, Edinburg, TX 78539, USA; Univ Texas Paso, Dept Civil Engn, El Paso, TX, USA; Concordia Univ, Dept Bldg Civil & Environm Engn, Montreal, PQ, Canada; Kyungpook Natl Univ, Sch Space Engn Sci, Daegu, South Korea; Kyungpook Natl Univ, Dept Robot & Smart Syst Engn, Daegu, South Korea; Kyungpook Natl Univ, Dept Safety Convergence, Daegu, South Korea; Kyung Hee Univ, Dept Civil Engn, Suwon, South Korea; Inst Adv Mfg IAM, College Stn, TX 77843, USA | 59366584400; 56523968800; 36150389500; 59773081100; 26967733100; 57198355299; 13806417200; 56319889200 | jinwoo.an@utrgv.edu; | GEOMECHANICS AND ENGINEERING | GEOMECH ENG | 2005-307X | 2092-6219 | 41 | 2 | SCIE | ENGINEERING, CIVIL;ENGINEERING, GEOLOGICAL | 2024 | 2.4 | 42.9 | N/A | 0 | 0 | coal fly ash; grouts; metakaolin; porous geopolymer; sinkhole remediation | MEMBRANE | coal fly ash; grouts; metakaolin; porous geopolymer; sinkhole remediation | Foamed products; X ray powder diffraction; Cement grouts; Coal fly ash; Experimental investigations; Geopolymer; Grout; Metakaolins; Molarity; Porous geopolymer; Sinkhole remediation; Sodium silicate; Aluminosilicates | English | 2025 | 2025-04-25 | 10.12989/gae.2025.41.2.297 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Piecewise Response Surface Methodology for Enhanced Modeling and Optimization of Complex Systems | This study introduces an innovative adaptation of response surface methodology (RSM) by implementing piecewise modeling to address the limitations inherent to traditional second-order polynomial models. Traditional RSM often struggles with complex, nonlinear system behaviors, particularly when variable interactions exhibit abrupt changes or asymmetrical relationships. By segmenting the response surface into distinct regions, each modeled separately, the piecewise approach enhances the methodology's adaptability and accuracy in predicting complex system dynamics. The effectiveness of the proposed piecewise RSM is demonstrated through case studies, including the optimization of tetracycline removal from water using a combined adsorption-coagulation process. This approach not only improves prediction accuracy but also integrates economic considerations into process optimization, which is crucial for industrial applications where cost-effectiveness is as important as operational efficiency. The results indicate that piecewise RSM can provide more accurate modeling of environmental and chemical engineering processes, providing a robust tool for improving experimental designs and process efficiencies while maintaining its simplicity. | Kim, Jiyun; Kim, Do-Gun; Ryu, Kyung Hwan | Sunchon Natl Univ, Dept Chem Engn, Sunchon 57922, South Korea; Kyungpook Natl Univ, Dept Chem Engn, Daegu 41566, South Korea; Sunchon Natl Univ, Dept Environm Engn, Sunchon 57922, South Korea | 59641573000; 36623899900; 55376077100 | khryu@scnu.ac.kr; | KOREAN JOURNAL OF CHEMICAL ENGINEERING | KOREAN J CHEM ENG | 0256-1115 | 1975-7220 | 42 | 3 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, CHEMICAL | 2024 | 3.2 | 42.9 | 2.41 | 2025-05-07 | 1 | 1 | Piecewise modeling; Response surface methodology; Design of experiment; Complex system optimization; Antibiotic adsorption | AT-A-TIME; ACTIVATED CARBON; DESIGNS | Antibiotic adsorption; Complex system optimization; Design of experiment; Piecewise modeling; Response surface methodology | Coagulation; Design of experiments; Large scale systems; Nonlinear systems; System theory; Antibiotic adsorption; Complex nonlinear system; Complex system optimization; Modeling and optimization; Piece-wise models; Piecewise response surfaces; Polynomial models; Response-surface methodology; Second-order polynomial; System optimizations; Cost engineering | English | 2025 | 2025-03 | 10.1007/s11814-024-00362-4 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Resemblance and Difference in Hydrodynamic Aspects Between Critical Current Density in Water Electrolysis and Critical Heat Flux in Boiling System | Boiling and hydrogen evolving systems both exhibit N-shaped curves, which include peak points known as critical heat flux (CHF) and critical current density (CCD). Since the CCD represents the maximum manageable current density, it would be a tentative obstacle to improving the hydrogen generation rate using a water electrolysis. However, studies explaining the mechanism of or modeling the critical current density (CCD) are scarcely performed. In contrast, substantial efforts have been made to develop the CHF models in the nuclear engineering field, resulting in well-accepted CHF correlations. Based on the analogous N-shaped curves in the two systems, the present study explores the CCD in hydrodynamic perspectives by adopting CHF models. The critical superficial velocities of gas (bubbles), where CHF or CCD occurs are introduced to compare the bubble generation rate adjacent to the surface. The result shows that the critical superficial velocity in the hydrogen evolving experiment is about 100 times smaller than that predicted by the CHF correlation. It seems that remarkably higher active nucleation site density in the hydrogen evolving system attributes the discrepancy. In a phenomenological standpoint, the critical number of surrounding bubbles limiting the gas generation rate was estimated as six in the hydrogen evolving system with a maximum error of 8.07%, which is similar to estimate of five in the boiling system. It is concluded that the CCD phenomenon is governed by the hydrodynamic behavior of the bubbles adjacent to the surface similar to that of the CHF. This work also insists that the key parameter governs CCD is active nucleation site density, while CHF can be predicted well by physical properties of fluid solely. © The Author(s), under exclusive licence to Korean Institute of Chemical Engineers, Seoul, Korea 2025. | Park, Haekyun | School of Energy Engineering, Kyungpook National University, 80 Daehak-Ro, Buk-Gu, Daegu, 41566, South Korea | 56541973600 | hkyunp@knu.ac.kr; | Korean Journal of Chemical Engineering | KOREAN J CHEM ENG | 0256-1115 | 1975-7220 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, CHEMICAL | 2024 | 3.2 | 42.9 | 2.41 | 2025-05-07 | 1 | Active nucleation site density; Analogy; Critical current density (CCD); Critical heat flux (CHF); Water electrolysis | Bubbles (in fluids); Critical current density (superconductivity); Nuclear engineering; 'current; Active nucleation site density; Analogy; Critical current density; Critical heat flux; Critical heat flux models; Evolving systems; Generation rate; Heat flux correlations; Water electrolysis; Hydrodynamics | English | Article in press | 2025 | 10.1007/s11814-025-00385-5 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Article | Study of CO2 absorption by cement paste containing amine compounds: a comparative study of diethylamine, dimethylamine and isopropylamine | The immobilization of carbon dioxide (CO2) using mineral carbonation technology is a promising approach for mitigating greenhouse gas emissions. This study investigated the enhancement of the CO2 absorption properties of cement pastes by employing various amine compounds such as diethylamine (DEA), dimethylamine (DMA), and isopropylamine (IPA). Systematic investigations were also carried out by incorporating the optimum concentrations of amine: 1%, 2%, and 3% for DEA, DMA, and IPA, respectively. Accelerated carbonation tests were conducted to evaluate the CO2 absorption characteristics and TGA-DSC and XRD analyses were performed to characterize the structural properties of the materials. The results indicated that the cement paste with amine additives exhibited higher CO2 absorption rates than those of the pristine cement paste. Notably, DMA demonstrated the most effective uptake with increasing amine concentration, achieving a 2.3 times faster absorption rate than the plain cement paste at 3% concentration. TGA-DSC analyses revealed a reduction in the calcium hydroxide content from 9.0 to 8.6% and an increase in the calcium carbonate content from 2.0 to 3.4% in the amine-added cement pastes. XRD analyses confirmed enhanced crystallinity with CO2 absorption, particularly with DMA exhibiting peak intensity increases of up to 40% compared to the control samples. This investigation indicates that amine-enhanced cement paste demonstrates effective CO2 absorption properties and has potential applications in environmental mitigation strategies and sustainable construction materials. | Kim, Tae-heon; Kuppusamy, Madhan; Velmurugan, Karthikeyan; Park, Shin-Deuk; Kim, Sun-Woo; Park, Sung-Sik; Kim, Wha-Jung | Kyungpook Natl Univ, Dept Civil Engn, Daegu 41566, South Korea; GOONWORLD Corp Res Inst, Daegu 41065, South Korea; Chosun Univ, Dept Chem Educ, Gwangju 61452, South Korea | KUPPUSAMY, MADHAN/AEA-7121-2022; KIM, SUN/HSB-7040-2023; Velmurugan, Karthikeyan/ABE-5205-2022 | 57204217686; 57203712410; 59563889300; 59446506900; 57089310400; 36241850300; 57203533494 | huny1016@krindus.co.kr; mitmadhan@gmail.com; karthi230407@gmail.com; yyy608ttn@naver.com; swookim@chosun.ac.kr; sungpark@knu.ac.kr; kimwj@knu.ac.kr; | INNOVATIVE INFRASTRUCTURE SOLUTIONS | INNOV INFRASTRUCT SO | 2364-4176 | 2364-4184 | 10 | 1 | ESCI | ENGINEERING, CIVIL | 2024 | 2.4 | 42.9 | 2.75 | 2025-05-07 | 1 | 1 | Carbon dioxide absorption; Cement paste; Amine compounds; TGA-DSC analysis; XRD analysis | CAPTURE | Amine compounds; Carbon dioxide absorption; Cement paste; TGA–DSC analysis; XRD analysis | English | 2025 | 2025-01 | 10.1007/s41062-024-01813-x | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Anti-Inflammatory Activity of Labdane and Norlabdane Diterpenoids from Leonurus sibiricus Related to Modulation of MAPKs Signaling Pathway | Leonurus sibiricus, a widely cultivated herbaceous plant in Asian countries, exhibits diverse medicinal applications. Recent studies emphasize its pharmacological properties and efficacy in promoting bone health. In addition to the known compounds and their pharmacological activities, in this study, we isolated and elucidated two new labdane-type diterpenoids, (3R,5R,6S,10S)-3,6-dihydroxy-15-ethoxy-7-oxolab- den-8(9),13(14)-dien-15,16-olide (1) and (4R,5R,10S)-18-hy- droxy-14,15-bisnorlabda-8-en-7,13-dione (2), a new natural phenolic compound, and a known compound from L. sibiricus using advanced spectroscopic techniques, including circular dichroism spectroscopy, high-resolution mass spectrometry, and 1- and 2-dimensional NMR. Among these, compound 1 demonstrated potent inhibition of nitric oxide (NO) production and inducible nitric oxide synthase (iNOS) mRNA expression levels, followed by compound 2. Whereas compounds 3 and 4 did not exhibit effectiveness in RAW264.7 macrophages. Moreover, compound 1 suppressed pro-inflammatory markers induced by lipopolysaccharide (LPS) stimulation. Compound 1 also suppressed iNOS and cyclooxygenase-2 (COX-2) protein levels and downregulated pro-inflammatory cytokines. Additionally, compound 1 showed inhibition of the phosphorylation of p38, JNK, and ERK, key mediators of the MAPK signaling pathway. These findings indicate that a natural-derived product, compound 1, might be a potential candidate as an anti-inflammation mediator. | Trang, Nguyen Minh; Vinh, Le Ba; Phong, Nguyen Viet; Yang, Seo Young | Chungnam Natl Univ, Coll Pharm, Daejeon, South Korea; Vietnam Acad Sci & Technol, Inst Marine Biochem IMBC, Hanoi, Vietnam; Kyungpook Natl Univ, Teachers Coll, Dept Biol Educ, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Inst Phylogen & Evolut, 80 Daehak Ro, Daegu 41566, South Korea | ; Nguyen, Viet Phong/AAQ-4207-2021; Le, Vinh/AAK-7699-2021; Nguyen, Minh Trang/HLX-0330-2023 | syy@knu.ac.kr; | PLANTA MEDICA | PLANTA MED | 0032-0943 | 1439-0221 | 91 | 01/02 | SCIE | CHEMISTRY, MEDICINAL;INTEGRATIVE & COMPLEMENTARY MEDICINE;PHARMACOLOGY & PHARMACY;PLANT SCIENCES | 2024 | 2 | 43.0 | 0 | Leonurus sibiricus; labdane diterpenoid; anti-inflammation; MAPKs | NF-KAPPA-B; EXTRACTS; CELLS; PHYTOCHEMISTRY; JAPONICUS | English | 2025 | 2025-01 | 10.1055/a-2440-5166 | 바로가기 | 바로가기 | 바로가기 | |||||||||

| ○ | ○ | Article | Suppression of stress granule assembly by pyridoxal hydrochloride attenuates oxidative damage in skin fibroblasts | Stress granules (SGs) are membrane-less cytoplasmic structures that form in response to various stress stimuli and play a critical role in maintaining cellular homeostasis. Dysregulation of SG dynamics has been implicated in several diseases, including neurodegenerative and inflammatory conditions; however, their role in skin biology remains largely unexplored. In this study, we identified pyridoxal hydrochloride, a form of vitamin B6, as a novel regulator of SG formation through a metabolite library screening. Our results demonstrate that pyridoxal hydrochloride significantly suppresses oxidative stress-induced SG formation in skin fibroblasts, exhibiting effects comparable to G3Ia, a known SG inhibitor. Furthermore, pyridoxal hydrochloride mitigates oxidative stress by reducing reactive oxygen species (ROS) accumulation and preventing cell toxicity. Notably, it also attenuates ROS-induced upregulation of MMP1, thereby preserving collagen1 stability. These findings suggest the crucial role of SGs in skin fibroblast homeostasis and suggest that pyridoxal hydrochloride may serve as a potential therapeutic agent for oxidative stress-related skin disorders. | Kim, Seong Hyun; Kim, Yong Hwan; Kim, Joon Bum; Park, Na Yeon; So, Jun Hee; Park, Daeun; Choi, Dong Kyu; Yeom, Eunbyul; Gwon, Youngdae; Jo, Doo Sin; Lee, Jin-A; Bae, Ji-Eun; Cho, Dong-Hyung | Kyungpook Natl Univ, Sch Life Sci, BK21 FOUR KNU Creat Biores Grp, Daegu, South Korea; Kyungpook Natl Univ, Organelle Inst, 80 Daehakro, Daegu 41566, South Korea; Sungkyunkwan Univ, Sch Med, Dept Mol Cell Biol, Suwon, South Korea; Orgasis Corp, Suwon, Gyeonggi Do, South Korea; Hannam Univ, Coll Life Sci & Nanotechnol, Dept Biol Sci & Biotechnol, Daejeon, South Korea | Gwon, Youngdae/AAK-1621-2021; Choi, dongKyu/LKL-2959-2024 | 57253406700; 57204676401; 57190611030; 57190609826; 59559562200; 59560569000; 57215816624; 56058004100; 55236433800; 56335489800; 35337365000; 57190605352; 35093684400 | jieunbae@knu.ac.kr; dhcho@knu.ac.kr; | BIOORGANIC & MEDICINAL CHEMISTRY LETTERS | BIOORG MED CHEM LETT | 0960-894X | 1464-3405 | 123 | SCIE | CHEMISTRY, MEDICINAL;CHEMISTRY, ORGANIC | 2024 | 2.2 | 43.0 | 0 | 2025-05-07 | 0 | 0 | Pyridoxal hydrochloride; Stress granules; MMP1; Collagen1; Skin fibroblasts | HYDROGEN-PEROXIDE; MATRIX METALLOPROTEINASES; INITIATION | Collagen1; MMP1; Pyridoxal hydrochloride; Skin fibroblasts; Stress granules | Dose-Response Relationship, Drug; Fibroblasts; Humans; Molecular Structure; Oxidative Stress; Pyridoxal; Reactive Oxygen Species; Skin; Stress Granules; Structure-Activity Relationship; pyridoxal; pyridoxine; reactive oxygen metabolite; RNA binding protein; pyridoxal; Article; controlled study; cytoplasm; homeostasis; nonhuman; oxidative stress; protein interaction; skin fibroblast; stress granule; chemical structure; chemistry; cytology; dose response; drug effect; fibroblast; human; metabolism; oxidative stress; skin; structure activity relation | English | 2025 | 2025-08-01 | 10.1016/j.bmcl.2025.130238 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | ZLDI-8 facilitates pexophagy by ROS-mediated activation of TFEB and ATM in HeLa cells | Autophagy-mediated organelle quality control is vital for cellular homeostasis. However, the mechanisms underlying selective autophagy of peroxisomes, known as pexophagy, are less well understood than those of other organelles, such as mitochondria. In this study, we screened a phosphatase inhibitor library using a cell-based system and identified several potent pexophagy inducers, including ZLDI-8, a known inhibitor of lymphoid- specific tyrosine phosphatase. Notably, treatment with ZLDI-8 selectively induces the loss of peroxisomes without affecting other organelles, such as mitochondria, the endoplasmic reticulum, or the Golgi apparatus. The peroxisome loss induced by ZLDI-8 was significantly blocked in ATG5-knockout HeLa cells, confirming its dependence on autophagy. We further found that ZLDI-8 treatment increases both cellular and peroxisomal reactive oxygen species (ROS), which were effectively scavenged by N-acetylcysteine (NAC). The increase in peroxisomal ROS leads to the activation of ATM kinase and the dephosphorylation of TFEB. Moreover, ROS scavenging prevents all of these processes. Taken together, these findings demonstrate that ZLDI-8 induces pexophagy through a mechanism involving peroxisomal ROS-mediated activation of TFEB and ATM. This study provides valuable insights into the molecular mechanisms regulating selective peroxisome degradation and potential therapeutic strategies for targeting pexophagy. | Kim, Yong Hwan; Kim, Joon Bum; Bae, Ji-Eun; Park, Na Yeon; Kim, Seong Hyun; Park, Daeun; So, Jun Hee; Lee, Jae Man; Jeong, Kwiwan; Choi, Dong Kyu; Jo, Doo Sin; Cho, Dong-Hyung | Kyungpook Natl Univ, Sch Life Sci, FOUR KNU Creat BioRearch Grp BK21, Daegu 41566, South Korea; Kyungpook Natl Univ, Organelle Inst, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Med, Dept Biochem & Cell Biol, Daegu 41944, South Korea; Gyeonggido Business & Sci Accelerator, Bio Ind Dept, Suwon 16229, South Korea; ORGASIS Corp, 260 Changyong Daero, Suwon 08826, South Korea | Choi, dongKyu/LKL-2959-2024 | 57204676401; 57190611030; 57190605352; 57190609826; 57253406700; 59560569000; 59559562200; 59813119100; 57197993212; 59815938900; 56335489800; 58950702200 | doosinjo@gmail.com; dhcho@knu.ac.kr; | BIOORGANIC & MEDICINAL CHEMISTRY LETTERS | BIOORG MED CHEM LETT | 0960-894X | 1464-3405 | 120 | SCIE | CHEMISTRY, MEDICINAL;CHEMISTRY, ORGANIC | 2024 | 2.2 | 43.0 | 0 | 2025-05-07 | 0 | 0 | ZLDI-8; Pexophagy; Peroxisome; ROS; TFEB | PEROXISOME BIOGENESIS; LIPID-METABOLISM; AUTOPHAGY; PROTEIN; IDENTIFICATION; DISEASE; MITOCHONDRIAL; MECHANISM; MEMBRANE; HEALTH | Peroxisome; Pexophagy; ROS; TFEB; ZLDI-8 | Ataxia Telangiectasia Mutated Proteins; Autophagy; Basic Helix-Loop-Helix Leucine Zipper Transcription Factors; Dose-Response Relationship, Drug; HeLa Cells; Humans; Molecular Structure; Peroxisomes; Reactive Oxygen Species; Structure-Activity Relationship; acetylcysteine; ATM protein; autophagy related protein 5; protein; protein tyrosine phosphatase inhibitor; reactive oxygen metabolite; TFEB; unclassified drug; zldi 8; ATM protein; ATM protein, human; basic helix loop helix leucine zipper transcription factor; reactive oxygen metabolite; TFEB protein, human; Article; autophagosome; autophagy (cellular); biogenesis; dephosphorylation; detoxification; endoplasmic reticulum; fluorescence microscopy; HeLa cell line; homeostasis; human; human cell; immunohistochemistry; lysosome; mitochondrion; peroxisome; pexophagy; Western blotting; chemical structure; dose response; drug effect; HeLa cell line; metabolism; structure activity relation | English | 2025 | 2025-05-01 | 10.1016/j.bmcl.2025.130130 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effects of neuromuscular electrical stimulation on neuromuscular function and muscle quality in patient following anterior cruciate ligament reconstruction | Anterior cruciate ligament reconstruction (ACLR) leads to quadriceps neuromuscular dysfunction, including impaired force control and muscle degradation. Neuromuscular electrical stimulation (NMES) is widely used in rehabilitation to improve muscle mass and strength; however, its effects on neuromuscular functions and muscle quality, such as motor unit (MU) behavior and force steadiness (FS), remain unclear. This study investigated the effects of NMES on neuromuscular function and muscle quality in individuals with ACLR who could walk normally. Ten male ACLR patients underwent NMES 3 times weekly for 6 weeks, with 30 contractions per session. Neuromuscular function was assessed via FS, maximum voluntary isometric contraction (MVIC), and MU behavior in the rectus femoris and vastus lateralis. Muscle quality was evaluated using muscle thickness (MT), echo intensity (EI), and ultrasound texture features. Measurements were taken at baseline and weeks 3 and 6. NMES significantly improved MVIC, FS, MU behavior, and muscle quality (MT, EI, and homogeneity) on the ACLR side, with significant interaction effects observed. At week 3, MVIC and FS showed no significant improvement; however, structural and qualitative muscle changes were evident. NMES effectively enhanced neuromuscular function, MU behavior, and muscle quality impaired by ACLR. However, a 3-week intervention may not be sufficientfor optimal neuromuscular recovery, highlighting the need for extended NMES protocols. | Jo, Hyeon-Deok; Kim, Maeng-Kyu | Kyungpook Natl Univ, Sports Sci Res Inst, Daegu, South Korea; Kyungpook Natl Univ, Sports Med Lab, Dept Phys Educ, Daegu, South Korea | 57226105432; 26021932400 | kimmk@knu.ac.kr; | JOURNAL OF EXERCISE REHABILITATION | J EXERC REHABIL | 2288-176X | 2288-1778 | 21 | 2 | ESCI | REHABILITATION | 2024 | 1.6 | 43.1 | N/A | 0 | 0 | Anterior cruciate ligament; Neuromuscular electrical stimulation; Neuromuscular function; Motor unit behavior; Muscle quality | FORCE STEADINESS; QUADRICEPS STRENGTH; RETURN; SPORT | Anterior cruciate ligament; Motor unit behavior; Muscle quality; Neuromuscular electrical stimu-lation; Neuromuscular function | English | 2025 | 2025-04 | 10.12965/jer.2550086.043 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
