| ○ | ○ | Article | Working Load Analysis of a 42 kW Class Agricultural Tractor According to Tillage Type and Gear Selection during Rotary Tillage Operation | The objective of this study was to analyze the effect of tillage type (i.e., primary and secondary tillage) and gear selection (P1L2 to P1L4) on the working load of tractor-implement systems during rotary tillage. Soil properties change with depth, and differences in properties along the depth distribution, such as the location of formation of the hardpan layer, internal friction angle, and moisture content, affect the load of rotary tillage operations. Therefore, the physical properties of soil along the field depth distribution were measured to analyze the effect of tillage type and gear selection on workload in rotary tillage. In addition, a load measurement system equipped with PTO torque meter, axle torque meter, proximity sensor, and RTK-GPS were configured on the 42 kW agricultural tractor. The experimental results show that the combination of tillage type and gear selection has a wide-ranging effect on the tractor's workload and performance when the rotavator operated at the same tilling depth. Overall working load was higher by up to 14% (engine) and 29.1% (PTO shaft) in primary tillage compared to secondary tillage when the gear selection was the same. When the tillage type is the same, it was analyzed that the overall average torque increased by up to 35.9% (engine) and 33.9% (PTO shaft) in P1L4 compared to P1L2 according to gear selection. Based on load analysis results, it was found that the effect of gear selection (Engine: 4-14%, PTO: 12.1-28.6%) on engine and PTO loads was higher than that of tillage type (Engine: 31.6-35.1%, PTO: 31.9-32.8%), and the power requirement tended to decrease in secondary tillage. Therefore, working load should be considered according to the soil environment and tillage type when designing agricultural machinery system. | Kim, Yeon-Soo; Bae, Bo-Min; Kim, Wan-Soo; Kim, Yong-Joo; Lee, Sang-Dae; Kim, Taek-Jin | Pusan Natl Univ, Dept Bioind Machinery Engn, Miryang 50463, South Korea; Kyungpook Natl Univ, Dept Bioind Machinery Engn, Daegu 41566, South Korea; Chungnam Natl Univ, Dept Biosyst Machinery Engn, Daejeon 34134, South Korea; Korea Inst Ind Technol KITECH, Smart Agr R&D Grp, Gimje 54325, South Korea; TYM R&D Ctr, Dept Drive Syst Team, Iksan 54576, South Korea | Kim, Yong-Joo/AAK-1840-2021; Kim, Ho Jin/IZP-7210-2023; Lee, Sang-Woong/ABF-6191-2020 | 57192923355; 58547463300; 57192918810; 57204759454; 59845799100; 57211191417 | skim23@pusan.ac.kr;hals806@pusan.ac.kr;wansoo.kim@knu.ac.kr;babina@cnu.ac.kr;sdlee96@kitech.re.kr;taek.kim@tym.world; | AGRICULTURE-BASEL | AGRICULTURE-BASEL | 2077-0472 | 13 | 8 | SCIE | AGRONOMY | 2023 | 3.3 | 15.5 | 0.67 | 2025-06-25 | 4 | 4 | working load; agricultural tractor; rotary tillage; soil property; tillage type | FORCE REQUIREMENTS; PTO LOAD; PERFORMANCE; TRANSMISSION; SPEED; DRAFT | agricultural tractor; rotary tillage; soil property; tillage type; working load | English | 2023 | 2023-08 | 10.3390/agriculture13081556 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Determination of ileal digestibility of tryptophan in tryptophan biomass for broilers using the direct and regression methods | A total of 372 Ross 308 male broilers were used in a 2-day trial to determine the ileal digestibility of tryptophan in tryptophan biomass using the direct and regression methods, and to compare the digestibility between the 2 methods. A nitrogen-free diet was prepared to estimate the basal endogenous losses of amino acids of birds. Two semi-purified diets were formulated to contain tryptophan biomass as the sole source of amino acids. Five corn-soybean meal-based diets consisted of a basal diet and 4 assay diets containing either 30 or 60 g/kg of tryptophan biomass A or B (TBA or TBB) at the expense of corn and soybean meal in the basal diet. The ratio of corn and soybean meal remained consistent across the basal and assay diets. Birds received a standard starter diet (193 g/kg crude protein) from day 0-19 post-hatch and 8 experimental diets for 2 days from day 19. On day 21 post-hatch, birds were asphyxiated with carbon dioxide and digesta samples from the distal section of the ileum were collected. The linear regression of tryptophan biomass-associated digested tryptophan against tryptophan biomass-associated tryptophan intake was conducted to determine the ileal tryptophan digestibility in tryptophan biomass. The apparent and standardized ileal digestibility of tryptophan determined by the direct method were 0.993 and 0.993 in TBA, and 0.995 and 0.996 in TBB, respectively. The apparent ileal digestibility of amino acids in corn-soybean meal-based diets quadratically increased (P < 0.05) as dietary levels of tryptophan biomass increased. The ileal digestibility of tryptophan determined by the regression method was 1.013 and 1.009 for TBA and TBB, respectively. The ileal digestibility of tryptophan in TBA derived from the regression method was greater (P = 0.033) than that of determined using the direct method, but no difference (P = 0.193) was observed in TBB. However, the ileal digestibility of tryptophan in the tryptophan biomass was close to 100 % irrespective of the method used. | Yoon, June Hyeok; Kong, Changsu | Kyungpook Natl Univ, Dept Anim Sci & Biotechnol, Sangju 37224, Gyeongsangbug, South Korea; Kyungpook Natl Univ, Dept Anim Sci, Sangju 37224, South Korea; Kyungpook Natl Univ, Res Inst Horse Ind, Sangju 37224, South Korea | 57995779900; 36027521600 | changsukong@gmail.com; | ANIMAL FEED SCIENCE AND TECHNOLOGY | ANIM FEED SCI TECH | 0377-8401 | 1873-2216 | 304 | SCIE | AGRICULTURE, DAIRY & ANIMAL SCIENCE | 2023 | 2.5 | 15.6 | 0.3 | 2025-06-25 | 1 | 1 | Tryptophan biomass; Broiler; Direct method; Ileal digestibility; Regression method | AMINO-ACID DIGESTIBILITY; FEED INGREDIENTS; SOYBEAN-MEAL; APPARENT; ENERGY; CORN; REQUIREMENTS; CHICKENS; PIGS | Broiler; Direct method; Ileal digestibility; Regression method; Tryptophan biomass | English | 2023 | 2023-10 | 10.1016/j.anifeedsci.2023.115732 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Transition to Sustainable Growth in South Korea: Investment and Trade under Uncertainty | This study examines major challenges for the Korean economy since East Asia has undergone significant transitions with the emergence of China in the 2000s. Because the transition has created uncertainties in the economy, South Korea has been exposed to a high degree of international competition in the turbulence of regional integration. We first employed structural vector autoregression to provide the impulse response of investment to various economic shocks, revealing the effects of structural changes and competition on industry. Furthermore, we identified the reasons behind low investment in South Korea over the past two decades. Second, as a proxy for structural change in the economy, we addressed the effects of extraneous shocks on the Korean economy by considering industry competitiveness. The results indicate that heightened uncertainty and export demands have shaped the dynamics of the Korean economy. In particular, the overall competitiveness of South Korea's merchant trade in major products such as mobile phones, automobiles, ships and optics has weakened due to intensifying competition and increasing overseas production. These changes suggest that South Korea needs to revise its economic development strategy, which has been largely driven by exports. To address the diverse challenges faced by the Korean economy, we highlighted the importance of indigenous dynamism for sustainable growth. | Jang, Tae-Seok; Oh, Sehwan | Kyungpook Natl Univ, Sch Econ & Trade, Daegu, South Korea; Kyungpook Natl Univ, Sch Business Adm, 80 Daehak Ro, Daegu 41566, South Korea | Oh, Sehwan/AAV-5689-2020; Jang, Tae-Seok/AFP-9841-2022 | 55951739600; 55879912900 | sehwano@knu.ac.kr; | MILLENNIAL ASIA | MILLENN ASIA | 0976-3996 | 2321-7081 | 14 | 3 | ESCI | AREA STUDIES | 2023 | 1.3 | 15.6 | 1.37 | 2025-06-25 | 4 | 6 | Investment; Korean economy; sustainable; trade; uncertainty | INNOVATION; FIRMS | Investment; Korean economy; sustainable; trade; uncertainty | English | 2023 | 2023-09 | 10.1177/09763996211065139 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Objective Assessment of Perioperative Anxiety using Functional Near-infrared Spectroscopy in Elderly Patients: A Prospective Randomized Observational Pilot Study | Background: Assessing and managing patient anxiety is essential to reduce postoperative complications in elderly patients. However, monitoring patient anxiety objectively is impossible. This study aimed to investigate the correlation between the level of fNIRS signals and anxiety in patients aged 65 and older undergoing artificial joint replacement surgery.Material and Methods: Sixty patients aged >= 65 years scheduled for elective total knee arthroplasty under spinal anesthesia were included. To differentiate the degree of anxiety, the patients were randomly divided into three groups, each consisting of 20 patients (group 1: administered normal saline as a placebo; groups 2 and 3: administered dexmedetomidine at a rate of 0.2 and 0.5 mu g/kg/h, respectively, for 10 min). Functional near-infrared spectroscopy was measured continuously for 10 min in each session (session 1: pre-anesthetic period; session 2: immediately after the spinal anesthesia period; session 3: normal saline or dexmedetomidine receiving period) in all patients. Vital signs were measured thrice at 5-min intervals during each session. State-Trait Anxiety Inventory -S (STAI-S) and Ramsay Sedation Scale (RSS) scores were assessed at the end of each session.Results: The STAI-S score was significantly correlated with power of bandwidth (p = 0.034). In addition, the RSS score was significantly correlated with BW 1, 2, and 3 (p = 0.010, p < 0.001, and p = 0.003, respectively).Conclusion: The STAI-S score and BW 3 were significantly correlated, suggesting that fNIRS might help objectively and directly monitor anxiety levels. | Kim, Hyae Jin; Lee, Dowon; Ri, Hyun-Su; Choi, Jongkwan; Choi, Jinhyung; Rhee, Seung Joon; Baik, Jiseok; Hwang, Boo-young; Park, Gayoung; Cha, Jihyun; Lee, Sang Don | Pusan Natl Univ, Sch Med, Dept Anesthesia & Pain Med, Busan, South Korea; Pusan Natl Univ Hosp, Biomed Res Inst, Dept Anesthesia & Pain Med, Pusan, South Korea; Kyungpook Natl Univ, Sch Med, Dept Anesthesiol & Pain Med, Daegu, South Korea; OBELAB Inc, Seoul, South Korea; Pusan Natl Univ, Pusan Natl Univ Hosp, Biomed Res Inst, Dept Orthopaed Surg,Sch Med, Busan, South Korea; Pusan Natl Univ, Yangsan Hosp, Sch Med, Dept Urol, Yangsan, South Korea; Biomed Res Inst, 179 Gudeok Ro, Busan 49241, South Korea | Kim, Hyae Jin/HIR-5575-2022 | 56668955600; 55981553800; 42462457900; 55660583900; 58667318800; 57196117405; 26029761100; 55273339500; 58668232100; 57713137100; 8147482300 | leedw@pusan.ac.kr; | INTERNATIONAL JOURNAL OF MEDICAL SCIENCES | INT J MED SCI | 1449-1907 | 20 | 13 | SCIE | MEDICINE, GENERAL & INTERNAL | 2023 | 3.2 | 15.7 | 0 | 2025-06-25 | 0 | 0 | Anesthesia; Spinal; Anxiety; Perioperative period; Spectroscopy; Near-Infrared | CEREBRAL-BLOOD-FLOW; PREOPERATIVE ANXIETY; COHERENCE ANALYSIS; RISK-FACTORS; INFORMATION; OXYGENATION; ANESTHESIA; MORTALITY | Anesthesia; Anxiety; Near-Infrared; Perioperative period; Spectroscopy; Spinal | Aged; Anxiety; Dexmedetomidine; Humans; Pilot Projects; Prospective Studies; Saline Solution; Spectroscopy, Near-Infrared; dexmedetomidine; sodium chloride; dexmedetomidine; aged; aging; anxiety; Article; controlled study; female; functional near-infrared spectroscopy; human; major clinical study; male; observational study; perioperative period; pilot study; premedication; prospective study; Ramsay Sedation Scale; randomized controlled trial; spinal anesthesia; State Trait Anxiety Inventory; total knee arthroplasty; vital sign; anxiety; diagnosis; etiology; near infrared spectroscopy | English | 2023 | 2023 | 10.7150/ijms.89287 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | OsCM regulates rice defence system in response to UV light supplemented with drought stress | center dot Studies on plant responses to combined abiotic stresses are very limited, especially in major crop plants. The current study evaluated the response of chorismate mutase overexpressor (OxCM) rice line to combined UV light and drought stress. center dot The experiments were conducted in pots in a growth chamber, and data were assessed for gene expression, antioxidant and hormone regulation, flavonoid accumulation, phenotypic variation, and amino acid accumulation. center dot Wild-type (WT) rice had reduced the growth and vigour, while transgenic rice maintained growth and vigour under combined UV light and drought stress. ROS and lipid peroxidation analysis revealed that chorismate mutase (OsCM) reduced oxidative stress mediated by ROS scavenging and reduced lipid peroxidation. The combined stresses reduced biosynthesis of total flavonoids, kaempferol and quercetin in WT plants, but increased significantly in plants with OxCM. Phytohormone analysis showed that SA was reduced by 50% in WT and 73% in transgenic plants, while ABA was reduced by 22% in WT plants but increased to 129% in transgenic plants. Expression of chorismate mutase regulates phenylalanine biosynthesis, UV light and drought stress-responsive genes, e.g., phenylalanine ammonia lyase (OsPAL), dehydrin (OsDHN), dehydration-responsive element-binding (OsDREB), ras-related protein 7 (OsRab7), ultraviolet-B resistance 8 (OsUVR8), WRKY transcription factor 89 (OsWRKY89) and tryptophan synthase alpha chain (OsTSA). Moreover, OsCM also increases accumulation of free amino acids (aspartic acid, glutamic acid, leucine, tyrosine, phenylalanine and proline) and sodium (Na), potassium (K), and calcium (Ca) ions in response to the combined stresses. center dot Together, these results suggest that chorismate mutase expression induces physiological, biochemical and molecular changes that enhance rice tolerance to combined UV light and drought stresses. | Jan, R.; Kim, N.; Asaf, S.; Lubna; Asif, S.; Du, X. -X.; Kim, E. -G.; Jang, Y. -H.; Kim, K. -M. | Kyungpook Natl Univ, Sch Appl Biosci, Div Plant Biosci, Coll Agr & Life Sci, Daegu, South Korea; Kyungpook Natl Univ, Coastal Agr Res Inst, Daegu, South Korea; Univ Nizwa, Nat & Med Sci Res Ctr, Nizwa, Oman; Natl Acad Agr Sci, Biosafty Div, Adm, Rural Dev, Jeonju, South Korea | Kim, Kyung-Min Kim/C-7007-2014; Jan, Rahmatullah/AIC-3439-2022; Asaf, Sajjad/ABA-3647-2021 | 57201981969; 57395985700; 56595059900; 57200621537; 57396413700; 57209098077; 57221496070; 57219901992; 34868260300 | kkm@knu.ac.kr; | PLANT BIOLOGY | PLANT BIOLOGY | 1435-8603 | 1438-8677 | 25 | 6 | SCIE | PLANT SCIENCES | 2023 | 4.2 | 15.7 | 1.22 | 2025-06-25 | 6 | 6 | Abscisic acid; drought stress; lipid peroxidation; reactive oxygen species; rice; UV light | B RADIATION; SALICYLIC-ACID; ULTRAVIOLET-RADIATION; IMPROVES DROUGHT; OVER-EXPRESSION; DEHYDRIN GENE; CELL-DEATH; TOLERANCE; L.; BIOSYNTHESIS | Abscisic acid; drought stress; lipid peroxidation; reactive oxygen species; rice; UV light | Amino Acids; Chorismate Mutase; Droughts; Flavonoids; Oryza; Reactive Oxygen Species; Ultraviolet Rays; amino acid; chorismate mutase; flavonoid; reactive oxygen metabolite; amino acid; ammonia; antioxidant; drought stress; growth rate; hormone; oxidative stress; protein; drought; genetics; Oryza; ultraviolet radiation | English | 2023 | 2023-10 | 10.1111/plb.13564 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Predicting the probability of good neurological outcome after in-hospital cardiac arrest based on prearrest factors: validation of the good outcome following attempted resuscitation 2 (GO-FAR 2) score | The Good Outcome Following Attempted Resuscitation (GO-FAR) 2 score is a prognostic tool developed to support decision-making for do-not-attempt-resuscitation (DNAR) orders by predicting neurological outcomes after in-hospital cardiac arrest (IHCA) based on prearrest variables. However, this scoring system requires further validation. We aimed to validate the GO-FAR 2 score for predicting good neurological outcome in Korean patients with IHCA. A single-centre registry of adult patients with IHCA from 2013 to 2017 was analysed. The primary outcome was discharge with good neurological outcome (Cerebral Performance Category score of 1 or 2). The patients were divided into four categories according to the GO-FAR 2 score: very poor (>= 5), poor (2-4), average (- 3 to 1), and above-average (= 2), only 0.9% had good outcome. GO-FAR 2 score >= 2 showed a sensitivity of 98.8% and a negative predictive value of 99.1% in predicting good neurological outcome. The GO-FAR 2 score can predict neurological outcome after IHCA. In particular, GO-FAR 2 score >= 2 may support decision-making for DNAR orders. | Kim, Boram; Hong, Seok-In; Kim, Youn-Jung; Cho, Yeon Joo; Kim, Won Young | Ulsan Univ, Asan Med Ctr, Dept Emergency Med, Coll Med, Seoul 05505, South Korea; Kyungpook Natl Univ, Dept Emergency Med, Sch Med, Daegu, South Korea | Kim, Yong Won/AAA-2134-2022 | 57944706500; 56763081800; 35280110200; 57219251787; 55661654200 | wonpia73@naver.com; | INTERNAL AND EMERGENCY MEDICINE | INTERN EMERG MED | 1828-0447 | 1970-9366 | 18 | 6 | SCIE | MEDICINE, GENERAL & INTERNAL | 2023 | 3.2 | 15.7 | 0.27 | 2025-06-25 | 1 | 1 | Asian; Cardiopulmonary resuscitation; GO-FAR; In-hospital cardiac arrest; Validation | CARDIOPULMONARY-RESUSCITATION; INTACT SURVIVAL; GUIDELINES; UPDATE | Asian; Cardiopulmonary resuscitation; GO-FAR; In-hospital cardiac arrest; Validation | Adult; Aged; Cardiopulmonary Resuscitation; Female; Heart Arrest; Hospitals; Humans; Male; Prognosis; Retrospective Studies; adult; aged; female; heart arrest; hospital; human; male; prognosis; resuscitation; retrospective study | English | 2023 | 2023-09 | 10.1007/s11739-023-03271-2 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Using a knowledge structure perspective to improve in-service teachers' content knowledge about active galaxies | The aim of this research study was to explore learning, i.e., changes in the knowledge structures of three in-service science teachers for the subject of active galaxies, through group activity conducted as part of a teacher training program. Qualitative methods were used in this study consisting of creating visual representations of the teachers' knowledge structures by analyzing texts, drawings, and data obtained through observations of and interviews with the teachers. The results show that new information acquired through conversations was incorporated into the teachers' preexisting knowledge structures through elaboration and organization. In the case of a teacher with a cognitive conflict, acceptance of the new information depended on the teacher's level of satisfaction with the explanations given. The main influence factor for the modification of knowledge structures was the teachers' orientation to science teaching. These findings suggest that in-service teacher training based on group activities can effectively enhance teachers' confidence in content knowledge (CK) of recent updates in scientific research. However, some format modifications are needed to guarantee efficient learning, such as the addition of a CK representation stage and discussion items based on the preactivity knowledge structure selected through expert review. | Eom, Heungjin; Shim, Hyunjin | Kyungpook Natl Univ, Dept Earth Sci Educ, Daegu 41566, South Korea; Seonju High Sch, Gumi 39211, South Korea; Kyungpook Natl Univ, Sci Educ Res Inst, Daegu 41566, South Korea | Shim, Hyunjin/LZI-7486-2025 | 58537353800; 14061137700 | hjshim@knu.ac.kr; | PHYSICAL REVIEW PHYSICS EDUCATION RESEARCH | PHYS REV PHYS EDUC R | 2469-9896 | 19 | 2 | SSCI;SCIE | EDUCATION & EDUCATIONAL RESEARCH;EDUCATION, SCIENTIFIC DISCIPLINES | 2023 | 2.6 | 15.7 | 0.17 | 2025-06-25 | 1 | 1 | PEDAGOGICAL CONTENT KNOWLEDGE; SCIENCE; MODELS | English | 2023 | 2023-08-10 | 10.1103/physrevphyseducres.19.020108 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||

| ○ | ○ | Article | Interior and H∞ feedback stabilization for sabra shell model of turbulence | Shell models of turbulence are representation of turbulence equations in Fourier domain. Various shell models are studied for their mathematical relevance and the numerical simulations that exhibit at most resemblance with turbulent flows. One of the mathematically well-studied shell model of turbulence is called sabra shell model. This work concerns with two important issues related to shell model, namely, feedback stabilization and robust stabilization. We first address stabilization problem related to sabra shell model of turbulence and prove that the system can be stabilized via finite dimensional controller. Thus, only finitely many modes of the shell model would suffice to stabilize the system. Later, we study robust stabilization in the presence of the unknown disturbance and corresponding control problem by solving an infinite time horizon max-min control problem. We first prove the H-infinity stabilization of the associated linearized system and characterize the optimal control in terms of a feedback operator by solving an algebraic Riccati equation. Using the same Riccati operator, we establish asymptotic stability of the nonlinear system. | Biswas, Tania; Dharmatti, Sheetal | Kyungpook Natl Univ, Dept Math, 80 Daehak Ro, Daegu, South Korea; IISER Thiruvananthapuram, Sch Math, Maruthamala PO Vithura, Trivandrum 695551, Kerala, India | 57202829208; 10840626600 | sheetal@iisertvm.ac.in; | MATHEMATICAL METHODS IN THE APPLIED SCIENCES | MATH METHOD APPL SCI | 0170-4214 | 1099-1476 | 46 | 2 | SCIE | MATHEMATICS, APPLIED | 2023 | 2.1 | 15.8 | 0.27 | 2025-06-25 | 1 | 1 | feedback control; H-infinity control; Navier-Stokes equations; Riccati equation; shell models; stabilization | BOUNDARY STABILIZATION; ROBUST-CONTROL; STOKES; SYSTEMS | feedback control; H∞ control; Navier-Stokes equations; Riccati equation; shell models; stabilization | Asymptotic stability; Feedback control; Navier Stokes equations; Riccati equations; Robust control; Shells (structures); Turbulence; Control problems; Feedback stabilization; Fourier-domain; H ∞; H ∞ control; Navier-Stokes equation; Robust stabilization; Sabra shell models; Shell models; Turbulence equations; Stabilization | English | 2023 | 2023-01-30 | 10.1002/mma.8615 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Investigating the law of tendential fall in the rate of profit based on feedback control | The rate of profit is a key element for understanding the movement of capitalism such as technological progress and economic crisis. Even though capitalists seek larger profit rates, there exists a tendency of stagnating or falling profit rates. According to Marx, the rate of profit would tend to decline in the long run as a result of technological progress, termed the law of tendential fall in the profit rate. This article introduces a novel approach based on the discrete-time feedback control mechanism to elucidate Marx's theory. Specifically, this study presents a mechanism and conditions to show how the effort to maximize the profit rate, implemented by designing an "appropriate" control law under the sampling of fiscal years, eventually leads to the gradual decrease in the rate of profit in the long run.(c) 2023 The Author(s).

| ○ | ○ | Article | Performance evaluation of AMQP over QUIC in the internet-of-thing networks | In today's world, the use of IoT devices is growing every day. For connecting IoT devices from various ven-dors and supporting a variety of IoT use cases, an interoperable protocol like AMQP is necessary. Researchers are striving to minimize delay because many IoT applications are sensitive to it. The trans-port layer protocol that is used underneath, such as TCP or UDP, is one of the main causes of the delay. Although TCP is slower than UDP because to the three-way handshake and the usage of TLS for security, it is more reliable than UDP. The Internet Engineering Task Force has introduced a new transport layer pro-tocol called QUIC that combines the best features of UDP and TCP to offer quick and reliable communi-cation. In this study, we integrated QUIC and AMQP1.0 using the Go programming language. The Docker tool was used to containerize the AMQP1.0 Broker, Sender, and Receiver implementations. The perfor-mance of AMQP1.0 over TCP and AMQP1.0 over QUIC was benchmarked in the NS3 simulator over various wireless networks including WiFi, 4G/LTE, and satellite. QUIC showed considerable improvement over lossy networks. The results showed that switching from TCP to QUIC at the transport level lowered Communication Time by 8.57% over Satellite network. Although Round Trip Time was almost same yet Start up Latency showed improvement of 52%, 38% and 34% in case of WiFi, 4G/LTE and Satellite respec-tively. In addition, the performance of AMQP1.0 over TCP and AMQP1.0 over QUIC has been evaluated over different Packet Loss values, the results show that AMQP1.0 over QUIC outperforms AMQP1.0 over TCP in all the cases. The testing results revealed that TCP performance was degraded by 20%, 16%, and 36% over WiFi, 4G/LTE, and satellite, respectively at Packet loss of 15%, while QUIC performance was only degraded by 4%, 8%, and 9% in each of these cases.(c) 2023 The Author(s).

| ○ | ○ | Article | Singular Value Decomposition of the Wave Forward Operator with Radial Variable Coefficients | Photoacoustic tomography (PAT) is a novel and promising technology in hybrid medical imaging that involves generating acoustic waves in the object of interest by stimulating electromagnetic energy. The acoustic wave is measured outside the object. One of the key mathematical problems in PAT is the reconstruction of the initial function that contains diagnostic information from the solution of the wave equation on the surface of the acoustic transducers. Herein, we propose a wave forward operator that assigns an initial function to obtain the solution of the wave equation on a unit sphere. Under the assumption of the radial variable speed of ultrasound, we obtain the singular value decomposition of this wave forward operator by determining the orthonormal basis of a certain Hilbert space comprising eigenfunctions. In addition, numerical simulation results obtained using the continuous Galerkin method are utilized to validate the inversion resulting from the singular value decomposition. | Moon, Minam; Hur, Injo; Moons, Sunghwan | Korea Mil Acad, Dept Math, Seoul 01805, South Korea; Chonnam Natl Univ, Dept Math Educ, Gwangju 61186, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Dept Math, Daegu 41566, South Korea | 55840599300; 55122034300; 56063426100 | hereandnow@kma.ac.kr;injohur@jnu.ac.kr;sunghwan.moon@knu.ac.kr; | SIAM JOURNAL ON IMAGING SCIENCES | SIAM J IMAGING SCI | 1936-4954 | 16 | 3 | SCIE | COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE;COMPUTER SCIENCE, SOFTWARE ENGINEERING;IMAGING SCIENCE & PHOTOGRAPHIC TECHNOLOGY;MATHEMATICS, APPLIED | 2023 | 2.1 | 15.8 | 0 | 2025-06-25 | 0 | 0 | photoacoustic; image reconstruction; wave equation; singular value decomposition; tomography; Helmholtz equation | INVERSION FORMULAS; RECONSTRUCTION; TOMOGRAPHY; TRANSFORM; EQUATION; FAMILY | Helmholtz equation; image reconstruction; photoacoustic; singular value decomposition; tomography; wave equation | Acoustic waves; Diagnosis; Eigenvalues and eigenfunctions; Electromagnetic waves; Galerkin methods; Medical imaging; Numerical methods; Photoacoustic effect; Tomography; Wave equations; Acoustics waves; Diagnostics informations; Helmholtz's equations; Images reconstruction; Initial functions; Mathematical problems; Photoacoustic tomography; Unit spheres; Variable coefficients; Variable speed; Image reconstruction | English | 2023 | 2023 | 10.1137/22m1511643 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Cell recognitive bioadhesive-based osteogenic barrier coating with localized delivery of bone morphogenetic protein-2 for accelerated guided bone regeneration | Titanium mesh (Ti-mesh) for guided bone regeneration (GBR) approaches has been extensively considered to offer space maintenance in reconstructing the alveolar ridge within bone defects due to its superb mechanical properties and biocompatibility. However, soft tissue invasion across the pores of the Ti-mesh and intrinsically limited bioactivity of the titanium substrates often hinder satisfactory clinical outcomes in GBR treatments. Here, a cell recognitive osteogenic barrier coating was proposed using a bioengineered mussel adhesive protein (MAP) fused with Alg-Gly-Asp (RGD) peptide to achieve highly accelerated bone regeneration. The fusion bioadhesive MAP-RGD exhibited outstanding performance as a bioactive physical barrier that enabled effective cell occlusion and a prolonged, localized delivery of bone morphogenetic protein-2 (BMP-2). The MAP-RGD@BMP-2 coating promoted in vitro cellular behaviors and osteogenic commitments of mesenchymal stem cells (MSCs) via the synergistic crosstalk effects of the RGD peptide and BMP-2 in a surface-bound manner. The facile gluing of MAP-RGD@BMP-2 onto the Ti-mesh led to a distinguishable acceleration of the in vivo formation of new bone in terms of quantity and maturity in a rat calvarial defect. Hence, our protein-based cell recognitive osteogenic barrier coating can be an excellent therapeutic platform to improve the clinical predictability of GBR treatment. | Jo, Yun Kee; Choi, Bong-Hyuk; Zhou, Cong; Jun, Sang Ho; Cha, Hyung Joon | Kyungpook Natl Univ, Sch Convergence, Dept Biomed Convergence Sci & Technol, Daegu, South Korea; Kyungpook Natl Univ, Cell & Matrix Res Inst, Daegu, South Korea; Nat Gluetech Co Ltd, Seoul, South Korea; Shandong Univ, Sch Stomatol, Jinan, Peoples R China; Korea Univ, Dept Oral & Maxillofacial Surg, Anam Hosp, Seoul, South Korea; Pohang Univ Sci & Technol, Dept Chem Engn, Pohang, South Korea; Pohang Univ Sci & Technol, Dept Chem Engn, Pohang 37673, South Korea; Korea Univ, Dept Oral & Maxillofacial Surg, Anam Hosp, Seoul 02841, South Korea | ; Joon, Hyung/AAO-8422-2020; Jun, Sang Ho/LCE-7830-2024 | 56123757800; 15053071900; 57206698242; 35114981500; 55954303800 | junsang@korea.ac.kr;hjcha@postech.ac.kr; | BIOENGINEERING & TRANSLATIONAL MEDICINE | BIOENG TRANSL MED | 2380-6761 | 8 | 3 | SCIE | ENGINEERING, BIOMEDICAL | 2023 | 6.1 | 15.9 | 0.85 | 2025-06-25 | 6 | 6 | barrier coating; bone morphogenetic protein-2; guided bone regeneration; mussel adhesive proteins; titanium mesh | BMP-2; DIFFERENTIATION; EXPRESSION; SUBSTRATE | barrier coating; bone morphogenetic protein-2; guided bone regeneration; mussel adhesive proteins; titanium mesh | Acceleration; Adhesives; Biocompatibility; Biomechanics; Bone; Coatings; Mesh generation; Molluscs; Peptides; Stem cells; Titanium; adhesive agent; bone morphogenetic protein 2; peptide; xylazine; zolertine; Barrier coatings; Bio adhesives; Bone morphogenetic protein-2; Guided bone regeneration; Localized delivery; Mussel adhesive proteins; Osteogenic; Regeneration treatment; RGD peptide; Titanium meshes; alveolar ridge; animal experiment; animal model; animal tissue; Article; behavior; biocompatibility; biodegradation; biological activity; biomechanics; bone density; bone regeneration; bone turnover; cell adhesion; cell differentiation; cell function; controlled study; drug delivery system; enzyme linked immunosorbent assay; histology; immunoblotting; male; micro-computed tomography; nonhuman; ossification; osteoblast; osteocyte; prediction; protein expression; protein phosphorylation; rat; scanning electron microscopy; tissue engineering; Cell culture | English | 2023 | 2023-05 | 10.1002/btm2.10493 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Laparoscopic right hemicolectomy with aortocaval lymphadenectomy, and pelvic peritoneum partial resection for ascending colon cancer | The aim of this video is to present the procedural details of laparoscopic right hemicolectomy with aortocaval (infrarenal aortic bifurcation) lymphadenectomy, partial resection of the pelvic peritoneum (peritoneal carcinomatosis index, 3), and hyperthermic intraperitoneal chemotherapy in a patient who received neoadjuvant chemotherapy for stage IVc colorectal cancer. The total operation time was 290 minutes, and the patient was discharged on a postoperative day 13 without any complications. No postoperative complications occurred until postoperative day 60. The pathological stage of the tumor was determined to be T3N2bM1c. The pelvic peritoneal nodule was pathologically confirmed as a metastatic lesion. Among the 12 harvested aortocaval lymph nodes, 6 were metastatic lymph nodes. The minimally invasive approach was safe and feasible in this highly selected patient with colon cancer, aortocaval lymph nodes, and peritoneal metastases. | Kim, Hannah; Seo, An Na; Park, Soo Yeun | Kyungpook Natl Univ Hosp, Dept Surg, Daegu, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Pathol, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Colorectal Canc Ctr, Sch Med, Daegu, South Korea; Kyungpook Natl Univ, Dept Colorectal Surg, Chilgok Hosp, 807 Hoguk Ro, Daegu 41404, South Korea | 58525469100; 55804153700; 40561578300 | psy-flower@daum.net; | ANNALS OF COLOPROCTOLOGY | ANN COLOPROCTOL | 2287-9714 | 2287-9722 | 39 | 3 | ESCI | GASTROENTEROLOGY & HEPATOLOGY;SURGERY | 2023 | 3 | 15.9 | 0.26 | 2025-06-25 | 1 | 1 | Colon neoplasms; Neoplasm metastasis; Laparoscopy; Hyperthermic intraperitoneal chemotherapy | METASTATIC COLORECTAL-CANCER; EXTRAHEPATIC DISEASE; LIVER METASTASES; PROGNOSIS | Colon neoplasms; Hyperthermic intraperitoneal chemotherapy; Laparoscopy; Neoplasm metastasis | anesthetic agent; antineoplastic agent; bevacizumab; CA 19-9 antigen; fluorodeoxyglucose f 18; fluorouracil plus leucovorin plus oxaliplatin; mitomycin; unclassified drug; abdominal cavity; abdominal radiography; adenocarcinoma; adult; aortocaval lymph node; Article; ascending colon; cancer chemotherapy; cancer regression; cancer staging; case report; clinical article; colorectal cancer; computer assisted tomography; dissection; frozen section; general anesthesia; greater omentum; hemicolectomy; hospital discharge; human; hyperthermic intraperitoneal chemotherapy; Kocher maneuver; laparoscopic surgery; lithotomy position; lymph node dissection; lymph node metastasis; male; middle aged; multidisciplinary team; multiple cycle treatment; neoadjuvant chemotherapy; oncological parameters; operation duration; paraaortic lymph node; pelvic peritoneum partial resection; pelvis radiography; peritoneal carcinomatosis index; peritoneum metastasis; positron emission tomography-computed tomography; postoperative period; preoperative period; primary tumor; radical resection; soft diet; surgeon; surgical margin; surgical technique; thorax radiography; treatment outcome | English | 2023 | 2023-06 | 10.3393/ac.2022.00780.0111 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Peptidylarginine deiminase 2 plays a key role in osteogenesis by enhancing RUNX2 stability through citrullination | Peptidylarginine deiminase (PADI) 2 catalyzes the post-translational conversion of peptidyl-arginine to peptidyl-citrulline in a process called citrullination. However, the precise functions of PADI2 in bone formation and homeostasis remain unknown. In this study, our objective was to elucidate the function and regulatory mechanisms of PADI2 in bone formation employing global and osteoblast-specific Padi2 knockout mice. Our findings demonstrate that Padi2 deficiency leads to the loss of bone mass and results in a cleidocranial dysplasia (CCD) phenotype with delayed calvarial ossification and clavicular hypoplasia, due to impaired osteoblast differentiation. Mechanistically, Padi2 depletion significantly reduces RUNX2 levels, as PADI2-dependent stabilization of RUNX2 protected it from ubiquitin-proteasomal degradation. Furthermore, we discovered that PADI2 binds to RUNX2 and citrullinates it, and identified ten PADI2-induced citrullination sites on RUNX2 through high-resolution LC-MS/MS analysis. Among these ten citrullination sites, the R381 mutation in mouse RUNX2 isoform 1 considerably reduces RUNX2 levels, underscoring the critical role of citrullination at this residue in maintaining RUNX2 protein stability. In conclusion, these results indicate that PADI2 plays a distinct role in bone formation and osteoblast differentiation by safeguarding RUNX2 against proteasomal degradation. In addition, we demonstrate that the loss-of-function of PADI2 is associated with CCD, thereby providing a new target for the treatment of bone diseases. | Kim, Hyun-Jung; Shin, Hye-Rim; Yoon, Heein; Park, Min-Sang; Kim, Byung-Gyu; Moon, Jae-, I; Kim, Woo-Jin; Park, Seung Gwa; Kim, Ki-Tae; Kim, Ha-Neui; Choi, Je-Yong; Ryoo, Hyun-Mo | Seoul Natl Univ, Sch Dent, Dept Mol Genet & Dent Pharmacol, Seoul 08826, South Korea; Seoul Natl Univ, Dent Res Inst, Seoul, South Korea; Inst Basic Sci IBS, Ctr Genom Integr, Ulsan, South Korea; Univ Arkansas Med Sci, Ctr Musculoskeletal Dis Res, Little Rock, AR USA; Univ Arkansas Med Sci, Ctr Osteoporosis & Metab Bone Dis, Dept Internal Med, Div Endocrinol & Metab, Little Rock, AR USA; Kyungpook Natl Univ, Cell & Matrix Res Inst, Skeletal Dis Anal Ctr,Sch Med, Korea Mouse Phenotyping Ctr,Dept Biochem & Cell Bi, Daegu, South Korea | Choi, Je-Yong/AAR-7334-2021; kim, woojin/HPG-7753-2023; Ryoo, Hyun-Mo/D-5839-2012; KIM, KI-TAE/AAX-3175-2020 | 57206210508; 56479679400; 57195284327; 58144114500; 55797167500; 57471738600; 57217161143; 57970501400; 57202965744; 55012027000; 7501391068; 7005485966 | hmryoo@snu.ac.kr; | CELL DEATH & DISEASE | CELL DEATH DIS | 2041-4889 | 14 | 8 | SCIE | CELL BIOLOGY | 2023 | 8.1 | 15.9 | 0.99 | 2025-06-25 | 9 | 7 | CORE-BINDING-FACTOR; CLEIDOCRANIAL DYSPLASIA; OSTEOBLAST DIFFERENTIATION; TRANSCRIPTION FACTOR; STATISTICAL-MODEL; MUTATIONS; PROTEIN; CBFA1; GENE; PATHOGENESIS | Animals; Chromatography, Liquid; Citrullination; Cleidocranial Dysplasia; Core Binding Factor Alpha 1 Subunit; Mice; Mice, Knockout; Osteogenesis; Tandem Mass Spectrometry; acid phosphatase tartrate resistant isoenzyme; proteasome; protein arginine deiminase type 2; transcription factor RUNX2; ubiquitin; transcription factor RUNX2; animal experiment; animal model; Article; bone development; bone disease; calvaria; citrullination; cleidocranial dysplasia; controlled study; gene expression; gene mutation; hypoplasia; knockout mouse; liquid chromatography-mass spectrometry; loss of function mutation; male; micro-computed tomography; mouse; nonhuman; ossification; osteoblast; phenotype; protein function; protein stability; regulatory mechanism; Sanger sequencing; animal; cleidocranial dysplasia; genetics; liquid chromatography; tandem mass spectrometry | English | 2023 | 2023-08-30 | 10.1038/s41419-023-06101-7 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
