| ○ | ○ | Article | Is ulnar shortening osteotomy effective for the treatment of ulnar styloid impaction syndrome compared to ulnar impaction syndrome? | PurposeThis study aimed at evaluating the outcomes of ulnar shortening osteotomy (USO) for the treatment of ulnar styloid impaction syndrome (USIS) and to compare them with those of USO for the treatment of ulnar impaction syndrome (UIS).MethodsWe enrolled 144 patients who underwent USO between March 2015 and October 2021. The patients were divided into a UIS group (group I, n = 93) and a USIS group (group II, n = 51). Clinical and radiological parameters, including Disabilities of the Arm, Shoulder, and Hand (DASH) score, ulnar variance, ulnar styloid length, and ulnar styloid process index (USPI), were collected pre-operatively and one year post-operatively, and a comparative analysis was performed.ResultsThe DASH score showed significant improvement in both groups (p < .001 and p < .001), and there was no significant difference between the two groups one year after surgery (p = .143). The USPI was significantly different between the two groups (p < .001). The ulno-lunate and ulno-triquetrum distances showed significant increases in both groups, with significant differences between the two groups (p = .020, and p < .001, respectively). The incidence of post-operative arthritic changes in the distal radioulnar joint was significantly greater in the UIS group than that in the USIS group (21 vs 3, respectively; p = .017). No remarkable differences were observed in the post-operative evidence of chondromalacia at the last follow-up between the two groups.ConclusionThe USO, which was performed as a treatment for USIS showed reliable outcomes compared to the USO for the treatment of UIS. Therefore, USO is a viable option for the treatment of USIS. | Kim, Kyung Wook; Kwak, Kwon Young; Lee, Hyung Jun; Kim, Seong Wook; Shim, Bum-Jin | Dankook Univ Hosp, Dept Orthopaed Surg, Cheonan 31116, South Korea; Kyungpook Natl Univ, Coll Med, Dept Orthopaed Surg, Daegu 41944, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Dept Orthopaed Surg, Daegu 41404, South Korea | 58392720700; 57212379642; 58535767900; 58536115900; 57201499293 | redpross@naver.com; | INTERNATIONAL ORTHOPAEDICS | INT ORTHOP | 0341-2695 | 1432-5195 | 47 | 11 | SCIE | ORTHOPEDICS | 2023 | 2 | 35.7 | 0.29 | 2025-06-25 | 1 | 1 | Ulnar styloid impaction syndrome; Ulnar impaction syndrome; Ulnar shortening osteotomy; Ulnar styloid process index | Ulnar impaction syndrome; Ulnar shortening osteotomy; Ulnar styloid impaction syndrome; Ulnar styloid process index | Humans; Joint Diseases; Osteotomy; Retrospective Studies; Treatment Outcome; Ulna; Wrist Joint; adult; arm disease; Article; chondromalacia; Disabilities of the Arm, Shoulder and Hand (score); female; follow up; human; length; lunate bone; major clinical study; male; osteotomy; outcome assessment; postoperative period; preoperative period; radioulnar joint; treatment outcome; triquetrum bone; ulnar head; ulnar impaction syndrome; ulnar shortening osteotomy; ulnar styloid impaction syndrome; ulnar styloid process; arthropathy; diagnostic imaging; osteotomy; retrospective study; treatment outcome; ulna; wrist | English | 2023 | 2023-11 | 10.1007/s00264-023-05928-1 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Protoplast isolation and transient gene expression in different petunia cultivars | The protocol optimized for Petunia hybrida cv. Mirage Rose produced high protoplast yields in 3 out of other 11 cultivars (Damask White, Dreams White, and Opera Supreme White). Factors optimized in the protoplast transfection process showed that the best transfection efficiency (80%) was obtained using 2.5 x 10(5) protoplast density, 40% polyethylene glycol (PEG) concentration, 10 mu g plasmid DNA, and 15 min of transfection time. Assessing the usability of the protocol for other cultivars (Damask White, Dreams White, and Opera Supreme White), a reasonable protoplast transfection efficiency (similar to 50%) was observed in the cultivars Dreams White and Opera Supreme White, with lower efficiency (similar to 50%) observed in the cv. Damask White. The transient expression of enhanced green fluorescent protein (eGFP) in the nucleus of the transfected protoplasts of all cultivars was confirmed using PCR. This system could be valuable for genome editing of unwanted genes in petunias using the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9) technology. Furthermore, it could contribute to other studies on protein subcellular localization, protein-protein interactions, and functional gene expression in the petunias. | Kang, Hyunhee; Naing, Aung Htay; Park, Soon Ki; Chung, Mi Young; Kim, Chang Kil | Kyungpook Natl Univ, Dept Hort, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Appl Biosci, Daegu 41566, South Korea; Sunchon Natl Univ, Dept Agr Educ, Sunchon 540950, Jeonnam, South Korea | Naing, Aung Htay/AAF-4277-2019 | 57217681910; 37112768100; 8055974900; 24821361600; 7409880701 | ckkim@knu.ac.kr; | PROTOPLASMA | PROTOPLASMA | 0033-183X | 1615-6102 | 260 | 1 | SCIE | CELL BIOLOGY;PLANT SCIENCES | 2023 | 2.5 | 35.7 | 0.95 | 2025-06-25 | 5 | 7 | eGFP; PCR; Petunia cultivars; Protoplast isolation; Transfection efficiency | MESOPHYLL PROTOPLASTS; SYSTEM; TRANSFORMATION | eGFP; PCR; Petunia cultivars; Protoplast isolation; Transfection efficiency | CRISPR-Cas Systems; Gene Editing; Gene Expression; Petunia; Protoplasts; CRISPR Cas system; gene editing; gene expression; genetics; Petunia; procedures; protoplast | English | 2023 | 2023-01 | 10.1007/s00709-022-01776-9 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Risk prediction models incorporating institutional case volume for mortality after hip fracture surgery in the elderly | Introduction While higher institutional case volume is associated with better postoperative outcomes in various types of surgery, institutional case volume has been rarely included in risk prediction models for surgical patients. This study aimed to develop and validate the predictive models incorporating institutional case volume for predicting in-hospital mortality and 1-year mortality after hip fracture surgery in the elderly. Materials and methods Data for all patients (>= 60 years) who underwent surgery for femur neck fracture, pertrochanteric fracture, or subtrochanteric fracture between January 2008 and December 2016 were extracted from the Korean National Health Insurance Service database. Patients were randomly assigned into the derivation cohort or the validation cohort in a 1:1 ratio. Risk prediction models for in-hospital mortality and 1-year mortality were developed in the derivation cohort using the logistic regression model. Covariates included age, sex, type of fracture, type of anaesthesia, transfusion, and comorbidities such as hypertension, diabetes, coronary artery disease, chronic kidney disease, cerebrovascular disease, and dementia. Two separate models, one with and the other without institutional case volume as a covariate, were constructed, evaluated, and compared using the likelihood ratio test. Based on the models, scoring systems for predicting in-hospital mortality and 1-year mortality were developed. Results Analysis of 196,842 patients showed 3.6% in-hospital mortality (7084/196,842) and 15.42% 1-year mortality (30,345/196,842). The model for predicting in-hospital mortality incorporating the institutional case volume demonstrated better discrimination (c-statistics 0.692) compared to the model without the institutional case volume (c-statistics 0.688; likelihood ratio test p value < 0.001). The performance of the model for predicting 1-year mortality was also better when incorporating institutional case volume (c-statistics 0.675 vs. 0.674; likelihood ratio test p value < 0.001). Conclusions The new institutional case volume incorporated scoring system may help to predict in-hospital mortality and 1-year mortality after hip fracture surgery in the elderly population. | Yoo, Seokha; Jang, Eun Jin; Jo, Junwoo; Lee, Hannah; Hwang, Yoonbin; Ryu, Ho Geol | Seoul Natl Univ, Dept Anaesthesiol & Pain Med, Seoul Natl Univ Hosp, Coll Med, 101 Daehak Ro, Seoul 03080, South Korea; Andong Natl Univ, Dept Informat Stat, Andong, Gyeongsangbuk D, South Korea; Kyungpook Natl Univ, Dept Stat, Daegu, South Korea | Yoo, Seokha/H-1638-2018; Ryu, Ho/J-5463-2012 | 55883558900; 37861741600; 57210425017; 55634905800; 57552135800; 7202277246 | hogeol@gmail.com; | ARCHIVES OF ORTHOPAEDIC AND TRAUMA SURGERY | ARCH ORTHOP TRAUM SU | 0936-8051 | 1434-3916 | 143 | 5 | SCIE | ORTHOPEDICS;SURGERY | 2023 | 2 | 35.7 | 0.87 | 2025-06-25 | 3 | 3 | Case volume; Elderly; Hip fracture; Mortality | HOSPITAL VOLUME; CANCER-SURGERY; SCORE; VALIDATION; ASSOCIATION; MORBIDITY; SURVIVAL; QUALITY; SYSTEM; ADULTS | Case volume; Elderly; Hip fracture; Mortality | Aged; Comorbidity; Hip Fractures; Hospital Mortality; Humans; Logistic Models; Retrospective Studies; Risk Factors; adult; aged; anesthesia; Article; bipolar hemiarthroplasty; cerebrovascular disease; chronic kidney failure; closed reduction (procedure); cohort analysis; comorbidity; controlled study; coronary artery disease; dementia; diabetes mellitus; female; femoral neck; femoral neck fracture; femur pertrochanteric fracture; femur subtrochanteric fracture; fracture external fixation; hip arthroplasty; hip fracture; hip replacement; hip surgery; hospitalization; human; hypertension; ICD-9; in-hospital mortality; major clinical study; male; mortality; national health insurance; open reduction (procedure); osteosynthesis; outcome assessment; postoperative period; predictive model; randomized controlled trial; retrospective study; risk assessment; risk factor; scoring system; validation process; hip fracture; hospital mortality; statistical model | English | 2023 | 2023-05 | 10.1007/s00402-022-04426-0 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Review | Surgical strategy of the treatment of atypical femoral fractures | The atypical femoral fracture (AFF) has been attracting significant attention because of its increasing incidence; additionally, its treatment is challenging from biological and mechanical aspects. Although surgery is often required to manage complete AFFs, clear guidelines for the surgical treatment of AFFs are currently sparse. We reviewed and described the surgical treatment of AFFs and the surveillance of the contralateral femur. For complete AFFs, cephalomedullary intramedullary nailing spanning the entire length of the femur can be used. Various surgical techniques to overcome the femoral bowing common in AFFs include a lateral entry point, external rotation of the nail, and the use of a nail with a small radius of curvature, or a contralateral nail. In the case of a narrow medullary canal, severe femoral bowing, or pre-existing implants, plate fixation may be considered as an alternative. For incomplete AFFs, prophylactic fixation depends on several risk factors, such as a subtrochanteric location, presence of a radiolucent line, functional pain, and condition of the contralateral femur; the same surgical principles as those in complete AFFs can be applied. Finally, once AFF is diagnosed, clinicians should recognize the increased risk of contralateral AFFs, and close surveillance of the contralateral femur is recommended. | Shim, Bum-Jin; Won, Heejae; Kim, Shin-Yoon; Baek, Seung-Hoon | Kyungpook Natl Univ, Chilgok Hosp, Dept Orthoped Surg, Daegu 41404, South Korea; Kyungpook Natl Univ, Coll Medincine, Dept Orthoped Surg, Daegu 41944, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Coll Med, Dept Orthoped Surg, 130 Dongdeok Ro, Daegu 41944, South Korea | ; Kim, Soo/J-5411-2012 | 57201499293; 57209207044; 26663842900; 56232924900 | insideme@paran.com; | WORLD JOURNAL OF ORTHOPEDICS | WORLD J ORTHOP | 2218-5836 | 14 | 5 | ESCI | ORTHOPEDICS | 2023 | 2 | 35.7 | 0.43 | 2025-06-25 | 3 | 4 | Atypical femoral fracture; Surgical treatment; Surveillance; Contralateral femur; Femoral bowing | FEMUR FRACTURES; HEALING TIME; OUTCOMES; COMPLICATION; MANAGEMENT; NONUNIONS; FIXATION | Atypical femoral fracture; Contralateral femur; Femoral bowing; Surgical treatment; Surveillance | English | 2023 | 2023-05-18 | 10.5312/wjo.v14.i5.302 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | The role of an augmentative plating in the management of femoral subtrochanteric nonunion | Introduction Owing to its distinct biomechanical properties, nonunion is common (7-20%) after intramedullary (IM) nailing of subtrochanteric femoral fractures. Unlike diaphyseal nonunion, it is difficult to provide sufficient stability by exchanging nailing alone in subtrochanteric nonunion. This study investigated the clinical outcomes of femoral subtrochanteric nonunion initially treated with an IM nail and subsequently managed with minimally invasive augmentative plate fixation.Materials and methods Nineteen patients were enrolled retrospectively. The mechanisms of initial injury were traffic accidents in 8, falls from a height in seven, and slipping in two patients. Two patients with atypical subtrochanteric femoral fractures without a specific trauma history were further included. All patients underwent IM nailing as the index operation. Nonunion surgery was performed an average of 45.2 weeks after the initial surgery. In cases of hardware damage and/or atrophic nonunion, exchange nailing and bone grafting were performed in addition to augmentative plating, as necessary. Conversely, augmentative plating alone was performed in cases of hypertrophic nonunion without any failure of the preexisting IM nail or malalignment. A narrow locking compression plate was fixed after contouring according to the shape of the proximal femur. The mean follow-up period was 36.1 months.Results Bony union was achieved in 18/19 patients (94.7%), at an average of 19.8 weeks after nonunion surgery. In the case that did not heal even after exchange nailing, additional plating and bone grafting, further autogenous bone grafting was required after 11 months, which healed uneventfully. There were 2 cases of soft tissue irritation over the plate, but no major complications were observed.Conclusions Additional plate augmentation over a retained IM nail yields satisfactory outcomes in terms of the bony union in subtrochanteric nonunion. Given its expected biomechanical superiority and relatively easy surgical technique, it may be a reasonable option for the management of femoral subtrochanteric nonunion. | Kim, Joon-Woo; Oh, Chang-Wug; Park, Kyeong-Hyeon; Oh, Jong-Keon; Yoon, Yong-Cheol; Hong, Wonki; Kim, Jaehyup | Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Orthopaed Surg, 130 Dongduk Ro, Daegu 41944, South Korea; Korea Univ Guro Hosp, Dept Orthopaed Surg, 148 Gurodong Ro, Seoul 08308, South Korea; Gachon Univ, Trauma Ctr, Orthoped Trauma Div, Coll Med, 21 Namdong Daero 774 Beon Gil, Incheon 21565, South Korea | ; Oh, Chang-Wug/AAO-4602-2021; Park, KyeongHyeon/KEH-4919-2024; Yong-Cheol, Yoon/HPD-8077-2023 | 22951329000; 22135834200; 56969984400; 7402155046; 37082544400; 57218322356; 58046882000 | cwoh@knu.ac.kr; | ARCHIVES OF ORTHOPAEDIC AND TRAUMA SURGERY | ARCH ORTHOP TRAUM SU | 0936-8051 | 1434-3916 | 143 | 8 | SCIE | ORTHOPEDICS;SURGERY | 2023 | 2 | 35.7 | 0.58 | 2025-06-25 | 2 | 2 | Subtrochanteric fracture; Nonunion; Minimally invasive augmentative plating; Intramedullary nailing; Exchange nailing | ASEPTIC NONUNION; GAMMA-NAIL; FRACTURES; FAILURE | Exchange nailing; Intramedullary nailing; Minimally invasive augmentative plating; Nonunion; Subtrochanteric fracture | Bone Nails; Bone Plates; Femoral Fractures; Femur; Fracture Fixation, Intramedullary; Fractures, Ununited; Hip Fractures; Humans; Retrospective Studies; Treatment Outcome; adult; aged; Article; atrophic nonunion; bone malformation; bone scintiscanning; bone transplantation; clinical article; controlled study; female; femur subtrochanteric fracture; fracture nonunion; human; intramedullary nailing; male; minimally invasive surgery; plate fixation; radiodiagnosis; retrospective study; surgical technique; traffic accident; very elderly; x-ray computed tomography; femur; femur fracture; fracture nonunion; hip fracture; intramedullary nailing; procedures; treatment outcome | English | 2023 | 2023-08 | 10.1007/s00402-023-04767-4 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |

| ○ | ○ | Article | Extracellular production of a thermostable Cellvibrio endolytic β-agarase in Escherichia coli for agarose liquefaction | Four GH16 family beta-agarases (GH16A, GH16B, GH16C, and GH16D), originated from an agarolytic bacterium Cellvibrio sp. KY-GH-1, were expressed in an Escherichia coli system and their activities were compared. Only GH16B (597 amino acids, 63.8 kDa), with N-terminal 22-amino acid signal sequence, was secreted into the culture supernatant and demonstrated a robust endolytic agarose hydrolyzing activity for producing neoagarotetraose (NA4) and neoagarohexaose (NA6) as end products. The optimal temperature and pH for the enzyme activity were 50 degrees C and 7.0, respectively. The enzyme was stable up to 50 degrees C and over a pH range of 5.0-8.0. The kinetic parameters, including Km, Vmax, kcat, and kcat/Km, of GH16B beta-agarases for agarose were 14.40 mg/mL, 542.0 U/mg, 576.3-s(-1), and 4.80 x-10(6) s(-1) M-1, respectively. The addition of 1 mM -MnCl2 and 15 mM tris(2- carboxyethyl)phosphine enhanced the enzymatic activity. When agarose or neoagaro- oligosaccharides were used as substrates, the end products of enzymatic catalysis were NA4 and NA6, whereas agaropentaose was produced along with NA4 and NA6 when agaro-oligosaccharides were used as substrates. Treatment of 9%[w/v] melted agarose with the enzyme (1.6 mu g/mL) under continuous magnetic stirring at 50 degrees C for 14 h resulted in efficient agarose liquefaction into NA4 and NA6. Purification of NA4 and NA6 from the enzymatic hydrolysate (9%[w/v] agarose, 20 mL) via Sephadex G-15 column chromatography yielded similar to 650 mg NA4/similar to 900 mg NA6 (i.e., similar to 85.3% of the theoretical maximum yield). These findings suggest that the recombinant thermostable GH16B ss-agarase is useful for agarose liquefaction to produce NA4 and NA6. | Lee, Hee Kyoung; Jang, Won Young; Kim, Young Ho | Kyungpook Natl Univ, Coll Nat Sci, Sch Life Sci & Biotechnol, Lab Immunobiol, 80 Daehak Ro, Daegu, South Korea | 58241864400; 56373427000; 57208312159 | ykim@knu.ac.kr; | AMB EXPRESS | AMB EXPRESS | 2191-0855 | 13 | 1 | SCIE | BIOTECHNOLOGY & APPLIED MICROBIOLOGY | 2023 | 3.5 | 35.9 | 0.59 | 2025-06-25 | 3 | 3 | Freshwater agar-degrading Cellvibrio; Neoagarotetraose; Neoagarohexaose; Recombinant his-tagged enzyme; Sephadex G-15 column chromatography; Thermostable endolytic GH16B beta-agarase | MARINE BACTERIUM; BIOCHEMICAL-CHARACTERIZATION; POLYSACCHARIDE; DEGRADATION; HYDROLYSIS; HYDROLASE; FAMILY; ENZYME; OLIGOSACCHARIDES; OVEREXPRESSION | Freshwater agar-degrading Cellvibrio; Neoagarohexaose; Neoagarotetraose; Recombinant his-tagged enzyme; Sephadex G-15 column chromatography; Thermostable endolytic GH16B β-agarase | agarose; cellulase; fresh water; genomic DNA; manganese chloride; monophenol monooxygenase; oligosaccharide; recombinant protein; sephadex; signal peptide; tris(2 carboxyethyl)phosphine; affinity chromatography; amino acid sequence; animal cell; animal experiment; animal model; animal tissue; Article; bacterial strain; bacterium culture; bacterium isolation; biocatalysis; biochemical analysis; catalysis; catalytic efficiency; Cellvibrio; colony forming unit; column chromatography; controlled study; drug synthesis; enzyme activity; Escherichia coli; extracellular production; hydrolysis; immunization; kinetic parameters; liquefaction; mass spectrometry; maximum reaction velocity; molecular cloning; mouse; nonhuman; optimal temperature; pH; phylogenetic tree; phylogeny; polyacrylamide gel electrophoresis; protein degradation; protein expression; protein phosphorylation; protein purification; protein quantitation; sequence alignment; sequence analysis; sequence homology; site directed mutagenesis; size exclusion chromatography; temperature; thin layer chromatography; Western blotting; zymography | English | 2023 | 2023-05-05 | 10.1186/s13568-023-01551-w | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | A Comparative Study of Optimal Individual Pitch Control Methods | Wind turbines are subjected to asymmetric loads and fatigue with subsequent increases in their dimension and capacity, leading to a reduction in their lifetime. To address this problem, the individual pitch control (IPC) technique is quite familiar in the control of wind turbines. IPC is used to reduce the tilt and yaw moments, simultaneously alleviating the turbine blade-root bending moments (BRBMs). This study discusses the performance of model predictive control (MPC), H-infinity (H & INFIN;), and proportional and integral (PI)-based IPC strategies integrated with collective pitch control. The performance of the reported controllers has been validated using the National Renewable Energy Laboratory (NREL) 5 MW full nonlinear reference wind turbine. Simulation studies are conducted at varying wind speeds and turbulent intensities as per international electrotechnical commission (IEC) norms. Comparative results in the time and frequency domains indicate that the H & INFIN; based IPC achieves enhanced control performance in terms of reduction in BRBMs and damage equivalent load compared to MPC and PI-based control strategies. | Routray, Abhinandan; Sivakumar, Nitin; Hur, Sung-ho; Bang, Deok-je | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Korea Electrotechnol Res Inst KERI, Nano Hybrid Technol Res Ctr, Changwon Si 51543, Gyeongsangnam D, South Korea | ROUTRAY, ABHINANDAN/IVU-9009-2023 | 57200499011; 59432626600; 36455858700; 24778272200 | abhinandan@knu.ac.kr;nitin@knu.ac.kr;shur@knu.ac.kr;djbang@keri.re.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 15 | 14 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2023 | 3.3 | 36.0 | 1.06 | 2025-06-25 | 9 | 8 | wind turbine; individual pitch control; optimal control; load reduction | H-INFINITY; WIND | individual pitch control; load reduction; optimal control; wind turbine | comparative study; control system; fatigue; wind turbine | English | 2023 | 2023-07 | 10.3390/su151410933 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | A Comprehensive Review on Machine Learning Techniques for Forecasting Wind Flow Pattern | The wind is a crucial factor in various domains such as weather forecasting, the wind power industry, agriculture, structural health monitoring, and so on. The variability and unpredictable nature of the wind is a challenge faced by most wind-energy-based sectors. Several atmospheric and geographical factors influence wind characteristics. Many wind forecasting methods and tools have been introduced since early times. Wind forecasting can be carried out short-, medium-, and long-term. The uncertainty factors of the wind challenge the accuracy of techniques. This article brings the general background of physical, statistical, and intelligent approaches and their methods used to predict wind characteristics and their challenges-this work's objective is to improve effective data-driven models for forecasting wind-power production. The investigation and listing of the effectiveness of improved machine learning models to estimate univariate wind-energy time-based data is crucially the prominent focus of this work. The performance of various ML predicting models was examined using ensemble learning (ES) models, such as boosted trees and bagged trees, Support Vector Regression (SVR) with distinctive kernels etc. Numerous neural networks have recently been constructed for forecasting wind speed and power due to artificial intelligence (AI) advancement. Based on the model summary, further directions for research and application developments can be planned. | Sri Preethaa, K.

| ○ | ○ | Article | Analysis of the Energy Performance of a Retrofitted Low-Rise Residential Building after an Energy Audit | The main reason for this research is to support the Korean government building retrofitting program initiated to evaluate energy usage trends, propose energy-saving technologies, and focus on reducing the energy demand in residential buildings through energy efficiency improvement. This is achieved by assessing the energy saved after introducing a simple retrofitting measure to an existing residential building. The energy savings in the building were realized after collecting relevant data from the house occupants, analyzing electricity bills, and introducing energy conservation measures (ECMS), leading to an improvement in the energy performance of the building. The building envelope saved 2098 kWh and 6307 kWh of energy via the heating and cooling equipment with an initial incremental cost of USD 500, fuel cost savings of USD 306, and a simple payback of 1.6 years. The analysis takes the occupants 2.6 years to recoup the initial cost of USD 2400 invested with an electricity savings of 2144 kWh. Also, 3.3 tons of CO2 emissions per year were reduced, equivalent to 3.3 people reducing energy use by 20%. Finally, the actual and simulated data are almost the same for the consumption period, with only a slight difference in October and December, given 0.92 as the Pearson Correlation coefficients. | Owolabi, Abdulhameed Babatunde; Yahaya, Abdullahi; Li, Hong Xian; Suh, Dongjun | Kyungpook Natl Univ, Reg Leading Res Ctr Smart Energy Syst, Sangju 37224, South Korea; Kyungpook Natl Univ, Dept Convergence & Fus Syst Engn, Sangju 37224, South Korea; Deakin Univ, Sch Architecture & Built Environm, Geelong Waterfront Campus, Geelong 3220, Australia | ; Li, Hong/ABC-9167-2021 | 57192210107; 58419707700; 36701739500; 36613529600 | owolabiabdulhameed@gmail.com;yahaya@knu.ac.kr;hong.li@deakin.edu.au;dongjunsuh@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 15 | 16 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2023 | 3.3 | 36.0 | 0.26 | 2025-06-25 | 2 | 2 | energy audit; energy saved; regression analysis; building performance; RETScreen Expert software | building performance; energy audit; energy saved; regression analysis; RETScreen Expert software | Korea; energy conservation; energy efficiency; equipment; regression analysis; savings; software | English | 2023 | 2023-08 | 10.3390/su151612129 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Artificial Intelligence/Machine Learning in Energy Management Systems, Control, and Optimization of Hydrogen Fuel Cell Vehicles | Environmental emissions, global warming, and energy-related concerns have accelerated the advancements in conventional vehicles that primarily use internal combustion engines. Among the existing technologies, hydrogen fuel cell electric vehicles and fuel cell hybrid electric vehicles may have minimal contributions to greenhouse gas emissions and thus are the prime choices for environmental concerns. However, energy management in fuel cell electric vehicles and fuel cell hybrid electric vehicles is a major challenge. Appropriate control strategies should be used for effective energy management in these vehicles. On the other hand, there has been significant progress in artificial intelligence, machine learning, and designing data-driven intelligent controllers. These techniques have found much attention within the community, and state-of-the-art energy management technologies have been developed based on them. This manuscript reviews the application of machine learning and intelligent controllers for prediction, control, energy management, and vehicle to everything (V2X) in hydrogen fuel cell vehicles. The effectiveness of data-driven control and optimization systems are investigated to evolve, classify, and compare, and future trends and directions for sustainability are discussed. | Fayyazi, Mojgan; Sardar, Paramjotsingh; Thomas, Sumit Infent; Daghigh, Roonak; Jamali, Ali; Esch, Thomas; Kemper, Hans; Langari, Reza; Khayyam, Hamid | Univ Melbourne, Sch Engn, Royal Melbourne Inst Technol RMIT, Melbourne, Vic 3083, Australia; FH Aachen Univ Appl Sci, Dept Aerosp Engn, D-52066 Aachen, Germany; Amal Jyothi Coll Engn, Dept Chem Engn, Kottayam 686518, Kerala, India; Univ Kurdistan, Dept Mech Engn, Sanandaj 6617715175, Iran; Kyungpook Natl Univ, Dept Artificial Intelligence, Daegu 37224, South Korea; Texas A&M Univ, Engn Technol & Ind Distribut ETID, College Stn, TX 77843 USA | ; daghigh, Roonak/AAZ-1669-2020 | 57218481711; 58911229700; 58910822500; 55405375500; 13805822900; 56942306700; 7007038918; 7006275578; 26422988300 | 3694457@student.rmit.edu.au;sardar@fh-aachen.de;sumit.153@hotmail.com;r.daghigh@uok.ac.ir;alijamali@knu.ac.kr;esch@fh-aachen.de;h.kemper@fh-aachen.de;rlangari@tamu.edu;hamid.khayyam@rmit.edu.au; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 15 | 6 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2023 | 3.3 | 36.0 | 8.2 | 2025-06-25 | 42 | 64 | intelligent energy management; artificial intelligence; machine learning; fuel cell vehicle; intelligent control; optimization system | HYBRID ELECTRIC VEHICLES; MODEL-PREDICTIVE CONTROL; DIAGNOSIS METHODOLOGIES; DEGRADATION PREDICTION; FUZZY-LOGIC; POWER; STRATEGIES; BATTERY; CYCLE; TECHNOLOGIES | artificial intelligence; fuel cell vehicle; intelligent control; intelligent energy management; machine learning; optimization system | artificial intelligence; electric vehicle; energy management; fuel cell; hydrogen; machine learning; optimization | English | 2023 | 2023-03 | 10.3390/su15065249 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Assessing Coastal Land-Use and Land-Cover Change Dynamics Using Geospatial Techniques | Geospatial techniques can be used to assess the dynamic conditions of coastal land use and land cover in order to make informed decisions about future management strategies for sustainable development through a combination of remote sensing data with field observations of shoreline characteristics along coastlines worldwide. Geospatial techniques offer an invaluable method for analyzing complex coastal systems at multiple scales. The coastal land use and land cover from the Subarnarekha (Orissa) to the Rasulpur estuaries (West Bengal) along the Bay of Bengal are dynamically modified by a complex interaction between land and sea. This is due to various dominating factors of physical and anthropogenic activities, which cause changes in the landscape. The main objective of this study was to identify the periodical transformation and changes in land-use/land-cover (LULC) features by the USGS-LULC classification method using a maximum-likelihood classifier (MLC) algorithm and satellite images for the period 1975-2018. The entire study area was divided into three 'littoral zones' (LZs). This will help in understanding how LULC has changed over time, as well as providing insight into human activities impacting on coastal environments. This study focused on five features selected for LULC classification, namely, built-up, vegetation, soil, sand and shallow-water areas. The purpose of this study was to investigate human encroachment near shore areas as well as the transformation of soil and sand into built-up areas over a 43-year period from 1975 to 2018 using geospatial techniques. To estimate the changes in the areas, a geodatabase was prepared for each LULC feature. Finally, statistical analysis was performed on all available datasets, which allowed the researchers to identify trends in land-cover change from 1975-2018 within each category, such as increasing deforestation and urbanization rates due to increased population growth. The results of the study show the expansion of shallow-water areas, which is one of the major factors influencing coastal erosion. Maximum shallow-water-level enhancement was observed in LZ I and LZ II. In LZ I, shallow water increased from 1 km(2) to 4.55 km(2). In LZ II, the initial 1.7 km(2) shallow-water area increased to 13.56 km(2), meaning an increase of 11.86 km(2) in shallow-water zones. A positive change was noticed in vegetation area, which increased from 2.82% (4.13 km(2)) to 15.46% (22.07 km(2)). Accuracy assessment was applied for all classified images, and more than 85% accuracy was considered for the overall accuracy assessment. Finally, Kappa coefficient statistics were adopted to complete the accuracy analysis, and 80% or more than 80% accuracy was obtained for all classified images. This information can also help inform policy makers about potential environmental impacts associated with certain activities, such as coastal development and agricultural expansion, so that appropriate steps can be taken towards mitigating these impacts before it is too late. | Nath, Anindita; Koley, Bappaditya; Choudhury, Tanupriya; Saraswati, Subhajit; Ray, Bidhan Chandra; Um, Jung-Sup; Sharma, Ashutosh | Jadavpur Univ, Dept Construct Engn, Kolkata 700032, India; Bankim Sardar Coll, Dept Geog, South 24 Parganas 743329, Tangrakhali, India; Univ Petr & Energy Studies, Sch Comp Sci, Dehra Dun 248007, India; Jadavpur Univ, Dept Chem, Kolkata 700032, India; Kyungpook Natl Univ, Coll Social Sci, Dept Geog, Daegu 41944, South Korea; Southern Fed Univ, Dept Informat & Analyt Secur Syst, Rostov Na Donu 344006, Russia | Um, Jung-Sup/F-5351-2018; Koley, Bappaditya/ABD-2038-2021; Choudhury, Tanupriya/AAB-8947-2020; Nath, Anindita/ADD-4573-2022; Sharma, Dr. Ashutosh/AAA-4601-2021 | 57219157935; 57219158700; 57193140084; 12809435400; 15837829900; 35173565000; 57191186424 | tanupriya@ddn.upes.ac.in;sharmaashutosh1326@gmail.com;tanupriya1986@gmail.com; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 15 | 9 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2023 | 3.3 | 36.0 | 2.78 | 2025-06-25 | 13 | 21 | land use; land cover; MLC algorithm; littoral zone; geodatabase; geospatial techniques; accuracy assessment | SEA-LEVEL RISE; ACCURACY ASSESSMENT; SHORELINE CHANGE; CLASSIFICATION; GIS; INDIA; UTTARAKHAND; FEATURES; IMAGERY; IMPACT | accuracy assessment; geodatabase; geospatial techniques; land use/land cover; littoral zone; MLC algorithm | Bay of Bengal; India; Indian Ocean; West Bengal; algorithm; coastal development; deforestation; land cover; land use change; remote sensing; shallow water; statistical analysis; sustainable development | English | 2023 | 2023-04-29 | 10.3390/su15097398 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Design of an Optimal Adoptive Fault Ride through Scheme for Overcurrent Protection of Grid-Forming Inverter-Based Resources under Symmetrical Faults | As the integration of inverter-based resources (IBRs) is rapidly increasing in regard to the existing power system, switching from grid-following (GFL) to grid-forming (GFM) inverter control is the solution to maintain grid resilience. However, additional overcurrent protection, especially during fault transition, is required due to limited overcurrent capability and the high magnitude of spikes during fault recovery in IBRs, specifically in the GFM control mode. Furthermore, the power system stability should not be compromised by the employment of additional fault ride through (FRT) schemes. This article presents the design and implementation of an adoptive fault ride through (FRT) scheme for grid-forming inverters under symmetrical fault conditions. The proposed adoptive FRT scheme is comprised of two cascaded power electronic-based circuits, i.e., fault current ride through and a spikes reactor. This adoptive FRT scheme optimizes the fault variables during the fault time and suppresses the fault clearing spikes, without affecting system stability. A three-bus inverter-based grid-forming model is used in MATLAB/Simulink for the implementation of the proposed scheme. Further, a conventionally used FRT scheme, which includes fault current reactors, is simulated in the same test environment for justification of the proposed adoptive scheme. The adoptive FRT scheme is simulated for both time domain and frequency domain to analyze the response of harmonic distortion with the suppression of the fault current. Moreover, the proposed scheme is also simulated under the GFL mode of IBRs to justify the reliability of the scheme. The overall simulation results and performance evaluation indices authenticate the optimal, fault tolerant, harmonic, and spike-free behavior of the proposed scheme at both the AC and DC side of the grid-forming inverters. | Islam, Saif Ul; Kim, Soobae | Kyungpook Natl Univ, Dept Elect Engn, Sch Elect & Elect Engn, Daegu 41566, South Korea | Islam, Saif ul/AAX-4521-2020 | 59083068700; 55377374400 | soobae.kim@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 15 | 8 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2023 | 3.3 | 36.0 | 0.4 | 2025-06-25 | 4 | 4 | grid-forming (GFM) inverters; PI controller; overcurrent protection; adoptive fault ride through scheme; optimization; point of common coupling (PCC); symmetrical faults | adoptive fault ride through scheme; grid-forming (GFM) inverters; optimization; overcurrent protection; PI controller; point of common coupling (PCC); symmetrical faults | adoption behavior; control system; coupling; fault; optimization; power generation; smart grid; symmetry | English | 2023 | 2023-04 | 10.3390/su15086705 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Developing an Optimal Ensemble Model to Estimate Building Demolition Waste Generation Rate | Smart management of construction and demolition (C & D) waste is imperative, and researchers have implemented machine learning for estimating waste generation. In Korea, the management of demolition waste (DW) is important due to old buildings, and it is necessary to predict the amount of DW to manage it. Thus, this study employed decision tree (DT)-based ensemble models (i.e., random forest-RF, extremely randomized trees-ET, gradient boosting machine-GBM), and extreme gradient boost-XGboost) based on data characteristics (i.e., small datasets with categorical inputs) to predict the demolition waste generation rate (DWGR) of buildings in urban redevelopment areas. As a result of the study, the RF and GBM algorithms showed better prediction performance than the ET and XGboost algorithms. Especially, RF (6 features, 450 estimators; mean, 1169.94 kg & BULL;m(-2)) and GBM (4 features, 300 estimators; mean, 1166.25 kg & BULL;m(-2)) yielded the top predictive performances. In addition, feature importance affecting DWGR was found to have a significant impact on the order of gross floor area (GFA) > location > roof material > wall material. The straightforward collection of features used here can facilitate benchmarking as a decision-making tool in demolition waste management plans for industry stakeholders and policy makers. Therefore, in the future, it is required to improve the predictive performance of the model by updating additional data and building a reliable dataset. | Cha, Gi-Wook; Hong, Won-Hwa; Choi, Se-Hyu; Kim, Young-Chan | Kyungpook Natl Univ, Sch Sci & Technol Accelerat Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, 80 Daehak Ro, Daegu 41566, South Korea; Dongguk Univ WISE Campus, Div Smart Safety Engn, 123 Dongdae Ro, Gyeongju 38066, South Korea | ; Choi, Se-Hyu/R-9264-2019 | 55754413300; 7401527968; 7408119153; 56463201400 | cgwgnr@gmail.com;hongwh@knu.ac.kr;shchoi@knu.ac.kr;yyoungchani@gmail.com; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 15 | 13 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2023 | 3.3 | 36.0 | 0.93 | 2025-06-25 | 5 | 7 | machine learning; random forest; extreme gradient boost; construction and demolition; waste generation | SUPPORT-VECTOR-REGRESSION; CONSTRUCTION; MACHINE; PREDICTION; MANAGEMENT; CHINA; AREA | construction and demolition; extreme gradient boost; machine learning; random forest; waste generation | algorithm; decision making; demolition; machine learning; policy making; stakeholder; waste management | English | 2023 | 2023-07 | 10.3390/su151310163 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effect of Curing Condition and Solvent Content on Mechanical Properties of Zein-Biopolymer-Treated Soil | The curing condition and solvent composition of biopolymer binders may impact their efficacy for soil stabilization. This study introduces a novel hydrophobic biopolymer, zein, and investigates the effects of solvent and curing conditions on the mechanical properties of zein-treated soils. The zein biopolymer is used to prepare cohesionless soil with various ethanol contents. Unconfined compressive strength and microscopic tests are used to investigate the treated specimens under two different curing conditions. The mechanical properties of the treated specimens are evaluated in terms of compressive strength and the secant elastic modulus. The experimental results show that the compressive strength and elastic modulus increase with the curing period under both curing conditions. Higher curing temperature improves the compressive strength of biopolymer-treated specimens. The linear relationship between compressive strength and the elastic modulus of zein-treated soils shows higher strength and a lower elastic modulus compared to rock. Furthermore, the zein biopolymer shows significant strength improvement compared to the existing biopolymers, including casein and lignin. Thus, the effects of solvent and curing conditions on the mechanical properties of zein-treated soil should be considered for its application to soil stabilization. | Babatunde, Quadri Olakunle; Son, Dong Geon; Kim, Sang Yeob; Byun, Yong-Hoon | Kyungpook Natl Univ, Sch Agr Civil & Bioind Engn, 80 Daehak ro, Daegu 41566, South Korea; Konkuk Univ, Dept Fire & Disaster Prevent, 268 Chungwon daero, Chungju 27478, South Korea | Byun, Yong-Hoon/JKI-8441-2023 | 58102290600; 58490365100; 57202787920; 42761048000 | yhbyun@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 15 | 15 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2023 | 3.3 | 36.0 | 0.66 | 2025-06-25 | 5 | 5 | biopolymer; cementation; curing condition; hydrophobic; soil stabilization; zein | biopolymer; cementation; curing condition; hydrophobic; soil stabilization; zein | cohesionless soil; compressive strength; elastic modulus; hydrophobicity; soil stabilization; temperature effect | English | 2023 | 2023-08 | 10.3390/su151512048 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
