| ○ | ○ | Article | Immunoregulatory effects of Lactococcus lactis-derived extracellular vesicles in allergic asthma | Background Probiotics have been shown to prevent various allergic diseases by producing extracellular vesicles (EVs). However, the role of EVs in allergic asthma has not yet been completely determined. Methods Gut microbial composition, mainly genera related to probiotics, was investigated in allergic asthmatic mice. Moreover, EVs were isolated from Lactococcus lactis (L. lactis, a selected bacterium) and EV proteins were identified by peptide mass fingerprinting. EV functions in immune responses were evaluated in vivo or ex vivo. Furthermore, the levels of specific IgG antibodies (an alternative marker for EV quantification) to L. lactis-EVs were measured by ELISA in the sera of 27 asthmatic patients and 26 healthy controls. Results Allergic asthmatic mice showed a lower proportion of Lactococcus compared to healthy mice. L. lactis was cultured and its EVs abundantly contained pyruvate kinase. When allergic asthmatic mice were intranasally treated with EVs, airway hyperresponsiveness, eosinophil number, cytokine secretion, and mucus production were significantly decreased. Moreover, L. lactis-EV treatment shifted immune responses from Th2 to Th1 by stimulating dendritic cells to produce IL-12. In addition, significantly lower levels of serum specific IgG4 (but not IgG1) to L. lactis-EVs were noted in asthmatic patients than in healthy controls. A positive correlation between the levels of EV-specific IgG4 and FEV1 (%), but a negative correlation between the levels of EV-specific IgG4 and IL-13 were observed. Conclusion These findings suggest that L. lactis-EVs may have immune-regulating effects on airway inflammation mediated by dendritic cell activation, providing a potential benefit for allergic asthma. | Lee, Dong-Hyun; Park, Han-Ki; Lee, Hee-Ra; Sohn, Hyeukjun; Sim, Soyoon; Park, Hyeon Ju; Shin, Yoo Seob; Kim, Yoon-Keun; Choi, Youngwoo; Park, Hae-Sim | Ajou Univ, Dept Allergy & Clin Immunol, Sch Med, 164 Worldcup Ro, Suwon, South Korea; Kyungpook Natl Univ, Sch Med, Dept Allergy & Clin Immunol, Daegu, South Korea; MD Healthcare Inc, Seoul, South Korea | Lee, Heera/GWQ-5858-2022; KIM, JEONGSEON/AAA-4643-2022; Park, Han-Ki/AAY-3102-2020 | 57195772614; 57218664064; 57211691912; 57207965264; 57211678490; 57216210464; 55552132100; 7410211755; 57195469608; 57192203361 | cyw3789@gmail.com;hspark@ajou.ac.kr; | CLINICAL AND TRANSLATIONAL ALLERGY | CLIN TRANSL ALLERGY | 2045-7022 | 12 | 3 | SCIE | ALLERGY | 2022 | 4.4 | 44.6 | 3.26 | 2025-06-25 | 35 | 37 | asthma; extracellular vesicles; Lactococcus lactis; microbiota; probiotics | REGULATORY T-CELLS; DENDRITIC CELLS; AIRWAY INFLAMMATION; PROBIOTICS; MODEL; MICROBIOTA; CYTOKINES; BACTERIA; ADHESION; IMMUNITY | asthma; extracellular vesicles; Lactococcus lactis; microbiota; probiotics | ciprofloxacin; clindamycin; abdominal pain; abscess; adult; Article; carcinoma; case report; echography; human; male; neutrophilia; pilonidal sinus; umbilical abscess; urachal sinus; urachus; X ray; young adult | English | 2022 | 2022-03 | 10.1002/clt2.12138 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Natural History and Influencing Factors of Chronic Urticaria in Children | Purpose: Chronic urticaria (CU) can reduce the quality of life of children and their parents, but there are only a few studies on the course of CU in children. This study aimed to investigate the natural course of CU in children and identify the factors that influence its prognosis. Methods: We evaluated 77 children diagnosed with CU, who were monitored for at least 48 months. Subjects were classified as either chronic spontaneous urticaria (CSU) or other CU, and the clinical features were compared. Remission was defined as having no symptoms without treatment for more than 1 year. The remission rate was analyzed, and the factors influencing the prognosis were investigated. Results: The average age of the study population was 5.96 +/- 4.06 years, and 64 (83.1%) patients had CSU. The remission rates at 6 months, 1 year, 2 years, 3 years, and 4 years after symptom onset were 22.1%, 40.3%, 52.0%, 63.7%, and 70.2%, respectively, for children with CU. For children with CSU, these values were 23.4%, 43.7%, 56.2%, 68.7%, and 75.0%, respectively. The total serum immunoglobulin E (IgE) levels were positively correlated with disease duration (r = 0.262, P = 0.021); no other factors were associated with the duration of the disease. Conclusions: A high proportion of children with CU were classified as CSU. No indicators, except for total IgE were found to predict the timing of spontaneous remission. The CU remission rate identified in this study is expected to be used as one of the reference data for the progress of CU in patients. | Kim, Hyeon A.; Hyun, Myung Chul; Choi, Bong Seok | Kyungpook Natl Univ, Sch Med, Dept Pediat, 130 Dongdeok Ro, Daegu 41944, South Korea | 57416123700; 8704315000; 56547873100 | bschoi@knu.ac.kr; | ALLERGY ASTHMA & IMMUNOLOGY RESEARCH | ALLERGY ASTHMA IMMUN | 2092-7355 | 2092-7363 | 14 | 1 | SCIE | ALLERGY;IMMUNOLOGY | 2022 | 4.4 | 44.6 | 0.56 | 2025-06-25 | 7 | 6 | Chronic urticaria; chronic spontaneous urticaria; chronic inducible urticaria; child | CHRONIC IDIOPATHIC URTICARIA; SERUM TOTAL IGE; PROGNOSTIC-FACTORS; SKIN-TEST; CHILDHOOD; MANAGEMENT; CLASSIFICATION; EPIDEMIOLOGY; AUTOIMMUNITY; DEFINITION | Child; Chronic inducible urticaria; Chronic spontaneous urticaria; Chronic urticaria | antinuclear antibody; complement component C3; complement component C4; eosinophil cationic protein; hepatitis B surface antigen; immunoglobulin E; nonsteroid antiinflammatory agent; vitamin D; adult; allergic rhinitis; angioneurotic edema; Article; asthma; atopic dermatitis; autoimmune disease; child; chronic spontaneous urticaria; chronic urticaria; clinical feature; controlled study; eosinophil count; eosinophilia; food allergy; hepatitis B; history; human; human experiment; liver function test; major clinical study; mycoplasmosis; prognosis; quality of life; remission; retrospective study; solar urticaria; young adult | English | 2022 | 2022-01 | 10.4168/aair.2022.14.1.73 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Rumex acetosella Inhibits Platelet Function via Impaired MAPK and Phosphoinositide 3-Kinase Signaling | Objective: To examine the antiplatelet and antithrombotic activity of Rumex acetosella extract. Methods: Standard light aggregometry was used for platelet aggregation, intracellular calcium mobilization assessed using Fura-2/AM, granule secretion (ATP release) by luminometer, and fibrinogen binding to integrin alpha(IIb)beta(3) detected using flow cytometry. Western blotting is carried out to determine the phosphorylation of mitogen-activated protein kinase (MAPK) and phosphoinositide 3-kinase (PI3K)/Akt signaling. Results: Rumex acetosella displayed the ability to inhibit platelet aggregation, calcium mobilization, granule secretion, and fibrinogen binding to integrin alpha(IIb)beta(3). Rumex acetosella has also down-regulated MAPK and PI3K/Akt phosphorylation (all P<0.01). Conclusion: Rumex acetosella extract exhibits antiplatelet activity via modulating GPVI signaling, and it may protect against the development of platelet-related cardiovascular diseases. | Jeon, Bo-Ra; Irfan, Muhammad; Lee, Seung Eun; Lee, Jeong Hoon; Rhee, Man Hee | Kyungpook Natl Univ, Coll Vet Med, Lab Physiol & Cell Signaling, Daegu 41566, South Korea; Natl Inst Hort & Herbal Sci NIHHS, Dept Herbal Crop Res, Eumseong 27709, South Korea | Rhee, Man/O-5705-2016 | 55856757000; 35069404400; 57219018706; 57203144480; 57211035357 | rheemh@knu.ac.kr; | CHINESE JOURNAL OF INTEGRATIVE MEDICINE | CHIN J INTEGR MED | 1672-0415 | 1993-0402 | 28 | 9 | SCIE | INTEGRATIVE & COMPLEMENTARY MEDICINE | 2022 | 2.9 | 44.6 | 0.51 | 2025-06-25 | 3 | 3 | antiplatelet; ethnomedicine; integrin alpha(IIb)beta(3); mitogen-activated protein kinase; Rumex acetosella L | CARDIOVASCULAR-DISEASE; TRADITIONAL MEDICINE; THROMBUS FORMATION; ACTIVATION; ANTIPLATELET; GINSENG; PHOSPHORYLATION; GINSENOSIDES | antiplatelet; ethnomedicine; integrin α<sub>IIb</sub>β<sub>3</sub>; mitogen-activated protein kinase; Rumex acetosella L | Blood Platelets; Calcium; Fibrinogen; Mitogen-Activated Protein Kinases; Phosphatidylinositol 3-Kinase; Phosphatidylinositol 3-Kinases; Phosphorylation; Plant Extracts; Platelet Aggregation; Platelet Aggregation Inhibitors; Platelet Glycoprotein GPIIb-IIIa Complex; Proto-Oncogene Proteins c-akt; Rumex; antithrombocytic agent; calcium; fibrinogen; fibrinogen receptor; mitogen activated protein kinase; phosphatidylinositol 3 kinase; plant extract; protein kinase B; metabolism; phosphorylation; Rumex; thrombocyte; thrombocyte aggregation | English | 2022 | 2022-09 | 10.1007/s11655-021-2873-0 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | A Fine-Grained Secure Service Provisioning Platform for Hypervisor Systems | As computing technology has been recently widely adopted, most computing devices provide security-related services as basic requirements, which is an important research issue for sustainability of computing devices. The rapid increase of software components makes it difficult to detect or prevent vulnerabilities in the large-size software. One of the prominent approaches for ensuring secure service is the isolation of service which allows the related code and data to be executed only in a particular area. In this paper, we provide a secure service provisioning platform for hypervisor systems. The main contribution of the proposed framework is to enhance the previous secure service provisioning platform in order to solve the non-preemption problem of secure services. Thus, the proposed framework improves the security isolation service in hypervisors and can be used for fine-grained secure service in secure embedded systems. | Seo, Junho; Lee, Seonah; Kim, Ki-Il; Kim, Kyong Hoon | Gyeongsang Natl Univ, Dept Informat, Jinju 52828, South Korea; Gyeongsang Natl Univ, Dept AI Convergence Engn Grad & Aerosp & Software, Jinju 52828, South Korea; Chungnam Natl Univ, Dept Comp Sci & Engn, Daejeon 34134, South Korea; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea | ; Kim, Honghyok/LDF-5356-2024 | 56440656600; 25822639700; 57193788419; 15065463500 | joy2net@gmail.com;saleese@gnu.ac.kr;kikim@cnu.ac.kr;kyong.kim@knu.ac.kr; | ELECTRONICS | ELECTRONICS-SWITZ | 2079-9292 | 11 | 10 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;PHYSICS, APPLIED | 2022 | 2.9 | 44.7 | 0.23 | 2025-06-25 | 1 | 3 | trusted service execution; security isolation; hypervisor; fine-grained secure service; secure service provisioning platform | VIRTUALIZATION | fine-grained secure service; hypervisor; secure service provisioning platform; security isolation; trusted service execution | English | 2022 | 2022-05 | 10.3390/electronics11101606 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | A Secure Personal Health Record Sharing System with Key Aggregate Dynamic Searchable Encryption | Recently, as interest in individualized health has increased, the Personal Health Record (PHR) has attracted a lot of attention for prognosis predictions and accurate diagnoses. Cloud servers have been used to manage the PHR system, but privacy concerns are evident since cloud servers process the entire PHR, which contains the sensitive information of patients. In addition, cloud servers centrally manage the PHR system so patients lose direct control over their own PHR and cloud servers can be an attractive target for malicious users. Therefore, ensuring the integrity and privacy of the PHR and allocating authorization to users are important issues. In this paper, we propose a secure PHR sharing system using a blockchain, InterPlanetary File System (IPFS), and smart contract to ensure PHR integrity and secure verification. To guarantee the patient's authority over the management of his/her own PHR, as well as provide convenient access, we suggest a key aggregate dynamic searchable encryption. We prove the security of the proposed scheme through informal and formal analyses including an Automated Verification of Internet Security Protocols and Applications (AVISPA) simulation, Burrows-Abadi-Needham (BAN) logic, and security-model-based games. Furthermore, we estimate the computational costs of the proposed scheme using a Multiprecision Integer and Rational Arithmetic Cryptographic Library (MIRACL) and compare the results with those of previous works. | Oh, Jihyeon; Lee, JoonYoung; Kim, MyeongHyun; Park, Youngho; Park, KiSung; Noh, SungKee | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Elect & Telecommun Res Inst, Blockchain Res Sect, Daejeon 34129, South Korea | ; Park, Kisung/KIG-3849-2024 | 57222066296; 57203970123; 57210278739; 56962990300; 57194833768; 56207592700 | parkyh@knu.ac.kr; | ELECTRONICS | ELECTRONICS-SWITZ | 2079-9292 | 11 | 19 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;PHYSICS, APPLIED | 2022 | 2.9 | 44.7 | 0.23 | 2025-06-25 | 1 | 3 | personal health record; key aggregate dynamic searchable encryption; blockchain; interplanetary file system | PROTOCOL; MANAGEMENT; INTERNET; DESIGN | blockchain; interplanetary file system; key aggregate dynamic searchable encryption; personal health record | English | 2022 | 2022-10 | 10.3390/electronics11193199 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Differential Evolution with Adaptive Grid-Based Mutation Strategy for Multi-Objective Optimization | Differential Evolution (DE) has been extensively adopted for multi-objective optimization due to its efficient and straightforward framework. In DE, the mutation operator influences the evolution of the population. In this paper, an adaptive Grid-based Multi-Objective Differential Evolution is proposed to address multi-objective optimization (ad-GrMODE). In ad-GrMODE, an adaptive grid environment is employed to perform a mutation strategy in conjunction with performance indicators. The grid reflects the convergence and diversity performance together but is associated with the user-specified parameter "div". To solve this problem, we adaptively tune the parameter "div". Among the DE mutation strategies, "DE/current-to-best/1" is applied extensively in single-objective optimization. This paper extends the application of "DE/current-to-best/1" to multi-objective optimization. In addition, a two-stage environmental selection is adopted in ad-GrMODE, where in the first stage, one-to-one selection between the parent and its corresponding offspring solution is performed. In addition, to preserve elitism, a stochastic selection is adopted with respect to performance metrics. We conducted experiments on 16 benchmark problems, including the DTLZ and WFG, to validate the performance of the proposed ad-GrMODE algorithm. Besides the benchmark problem, we evaluated the performance of the proposed method on real-world problems. Results of the experiments show that the proposed algorithm outperforms the eight state-of-the-art algorithms. | Ghorbanpour, Samira; Jin, Yuwei; Han, Sekyung | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea | ; Jin, Yuwei/LIR-2747-2024 | 57207109590; 57212253293; 36023785800 | skhan@knu.ac.kr; | PROCESSES | PROCESSES | 2227-9717 | 10 | 11 | SCIE | ENGINEERING, CHEMICAL | 2022 | 3.5 | 44.7 | 0.25 | 2025-06-25 | 3 | 3 | multi-objective optimization; Differential Evolution (DE); adaptive grid environment; mutation; binomial crossover | ALGORITHM; SELECTION | adaptive grid environment; binomial crossover; Differential Evolution (DE); multi-objective optimization; mutation | English | 2022 | 2022-11 | 10.3390/pr10112316 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Efficient Perineural Invasion Detection of Histopathological Images Using U-Net | Perineural invasion (PNI), a sign of poor diagnosis and tumor metastasis, is common in a variety of malignant tumors. The infiltrating patterns and morphologies of tumors vary by organ and histological diversity, making PNI detection difficult in biopsy, which must be performed manually by pathologists. As the diameters of PNI nerves are measured on a millimeter scale, the PNI region is extremely small compared to the whole pathological image. In this study, an efficient deep learning-based method is proposed for detecting PNI regions in multiple types of cancers using only PNI annotations without detailed segmentation maps for each nerve and tumor cells obtained by pathologists. The key idea of the proposed method is to train the adopted deep learning model, U-Net, to capture the boundary regions where two features coexist. A boundary dilation method and a loss combination technique are proposed to improve the detection performance of PNI without requiring full segmentation maps. Experiments were conducted with various combinations of boundary dilation widths and loss functions. It is confirmed that the proposed method effectively improves PNI detection performance from 0.188 to 0.275. Additional experiments were also performed on normal nerve detection to validate the applicability of the proposed method to the general boundary detection tasks. The experimental results demonstrate that the proposed method is also effective for general tasks, and it improved nerve detection performance from 0.511 to 0.693. | Park, Youngjae; Park, Jinhee; Jang, Gil-Jin | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Neopons, Daegu 41404, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | 57697146800; 57697146900; 7102646102 | wim-c@knu.ac.kr;pjhdrin@knu.ac.kr;gjang@ee.knu.ac.kr; | ELECTRONICS | ELECTRONICS-SWITZ | 2079-9292 | 11 | 10 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;PHYSICS, APPLIED | 2022 | 2.9 | 44.7 | 0.23 | 2025-06-25 | 3 | 3 | deep learning; U-Net; boundary detection; perineural invasion detection; histopathological image | PATHOLOGY | boundary detection; deep learning; histopathological image; perineural invasion detection; U-Net | English | 2022 | 2022-05 | 10.3390/electronics11101649 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Evaluating the Efficiency of Connected and Automated Buses Platooning in Mixed Traffic Environment | Due to the battery capacity limitation of battery electric vehicles (BEVs), the importance of minimizing energy consumption has been increasing in recent years. In the mean time, for improving vehicle energy efficiency, platooning has attracted attention of several automakers. Using the connected and automated vehicles (CAVs) technology, platooning can achieve a longer driving range while preserving a closer distance from the preceding vehicle, resulting in the minimization of the aerodynamic force. However, undesired behaviors of human-driven vehicles (HVs) in the platooning group can prohibit the maximization of the energy efficiency. In this paper, we developed a speed planner based on the model predictive control (MPC) to minimize the total platooning energy consumption, and HVs were programmed to maintain a long enough distance from the preceding vehicle to avoid collision. The simulations were performed to determine how HV influences the efficiencies of the platooning group, which is composed of CAVs and HVs together, in several scenarios including the different positions and numbers of the HVs. Test results show that the CAVs planned by our approach reduces energy consumption by about 4% or more than 4% compared to that of the HVs. | Park, Suyong; Nam, Sanghyeon; Sankar, Gokul S.; Han, Kyoungseok | Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea; Ford Motor Co, Dearborn, MI 48126 USA | 57560254700; 58592160700; 55326286700; 56465294700 | kyoungsh@knu.ac.kr; | ELECTRONICS | ELECTRONICS-SWITZ | 2079-9292 | 11 | 19 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;PHYSICS, APPLIED | 2022 | 2.9 | 44.7 | 0.54 | 2025-06-25 | 7 | 7 | platooning; connected and automated vehicle (CAV); electric bus; energy optimization; model predictive control | STRATEGY | connected and automated vehicle (CAV); electric bus; energy optimization; model predictive control; platooning | English | 2022 | 2022-10 | 10.3390/electronics11193231 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Importance of Solvent Evaporation Temperature in Pre-Annealing Stage for Solution-Processed Zinc Tin Oxide Thin-Film Transistors | We focused on the importance of solvent evaporation governed by the temperature of the pre-annealing stage (T-S) in solution-processed zinc tin oxide (ZTO) thin-film transistors (TFTs). We controlled T-S based on the boiling point (B-P) of the solvent used. When T-S reaches the B-P, the field effect mobility is found to be about 1.03 cm2/V s, which is 10 times larger than the T-S < B-p case (0.13 cm(2)/V s). The reason is presumed to be that residual organic defects are effectively removed as T-S increases. In addition, when Ts is beyond B-p, the mobility is rather decreased due to structural defects such as pores and pinholes. Based on our results, it is noted that T-S plays a significant role in the enhancement of electrical performance and stability of solution-processed ZTO TFTs. | Jeon, Sang-Hwa; Wang, Ziyuan; Seo, Kyeong-Ho; Feng, Junhao; Zhang, Xue; Park, Jaehoon; Bae, Jin-Hyuk | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Shangdong Univ Sci & Technol, Coll Ocean Sci & Engn, Qingdao 266590, Peoples R China; Hallym Univ, Dept Elect Engn, Chuncheon 24252, Peoples R China; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, Peoples R China | Wang, Ziyuan/KIC-5864-2024; Feng, Junhao/KZF-5875-2024 | 57552166800; 57552166900; 57211978931; 57905127500; 55949859900; 55717156300; 35326180700 | jaypark@hallym.ac.kr;jhbae@ee.knu.ac.kr; | ELECTRONICS | ELECTRONICS-SWITZ | 2079-9292 | 11 | 18 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;PHYSICS, APPLIED | 2022 | 2.9 | 44.7 | 0.31 | 2025-06-25 | 4 | 4 | amorphous oxide semiconductors; zinc tin oxide; solution process; thin-film transistor; pre-annealing | PERFORMANCE; LAYER | amorphous oxide semiconductors; pre-annealing; solution process; thin-film transistor; zinc tin oxide | English | 2022 | 2022-09 | 10.3390/electronics11182822 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Kinetics of Reductive Dissolution of a Magnetite Specimen Using Oxalic Acid | The removal of radionuclides from the primary coolant system of nuclear power plants occurs with the dissolution of corrosion metal oxide layers deposited with the radionuclides. Kinetic dissolution experiments were conducted with a synthetic magnetite specimen in the form of a thin plate using an aqueous solution of oxalic acid as a reducing agent. The effects of acid concentration and temperature were investigated on the kinetics of the reductive dissolution of a magnetite specimen. In particular, the kinetic experiments were performed in a wide temperature range from low (57 degrees C) to high (120 degrees C), above the normal boiling point of water. The dissolution of magnetite increased with increasing acid concentration and temperature. The acid concentration dependence of the dissolution reaction rate of Fe at a given temperature was correlated with the nth power of the oxalic acid concentration. Additionally, the temperature dependence of the dissolution reaction rate of Fe at a fixed oxalic acid concentration was studied with an Arrhenius-type equation. | Kim, Hye Rim; Park, Jae Kwan; Lee, Su In; Oh, Wonzin; Kim, Jeongju; Kim, Chorong; Lee, Byung-Chul | Hannam Univ, Dept Chem Engn, Daejeon 34054, South Korea; Kyungpook Natl Univ, Res Inst Adv Energy Technol, Daegu 41566, South Korea; KHNP Cent Res Inst, Daejeon 34101, South Korea | 57607571600; 57610230000; 57606498400; 7201606916; 57471049800; 56158823200; 57203795455 | mnb1756@naver.com;qkrworhks01@gmail.com;enddl_dl@naver.com;wonzin@knu.ac.kr;jeongju.kim@khnp.co.kr;chorong.kim@khnp.co.kr;bclee@hnu.kr; | PROCESSES | PROCESSES | 2227-9717 | 10 | 4 | SCIE | ENGINEERING, CHEMICAL | 2022 | 3.5 | 44.7 | 0.42 | 2025-06-25 | 5 | 5 | magnetite specimen; chemical decontamination; reductive dissolution; kinetics; oxalic acid | CITRIC-ACID | chemical decontamination; kinetics; magnetite specimen; oxalic acid; reductive dissolution | English | 2022 | 2022-04 | 10.3390/pr10040696 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Lg = 50 nm Gate-All-Around In0.53Ga0.47As Nanosheet MOSFETs with Regrown In0.53Ga0.47As Contacts | In this paper, we report the fabrication and characterization of Lg = 50 nm Gate-All-Around (GAA) In0.53Ga0.47As nanosheet (NS) metal-oxide-semiconductor field-effect transistors (MOSFETs) with sub-20 nm nanosheet thickness that were fabricated through an S/D regrowth process. The fabricated GAA In0.53Ga0.47As NS MOSFETs feature a bi-layer high-k dielectric layer of Al2O3/HfO2, together with an ALD-grown TiN metal-gate in a cross-coupled manner. The device with Lg = 50 nm, WNS = 200 nm and tNS = 10 nm exhibited an excellent combination of subthreshold-swing behavior (S < 80 mV/dec.) and carrier transport properties (gmₘₐₓ = 1.86 mS/μm and ION = 0.4 mA/μm) at VDS = 0.5 V. To the best of our knowledge, this is the first demonstration of InxGa1-xAs GAA NS MOSFETs that would be directly applicable for their use in future multi-bridged channel (MBC) devices. © 2022 by the authors. | Lee, In-Geun; Jo, Hyeon-Bhin; Baek, Ji-Min; Lee, Sang-Tae; Choi, Su-Min; Kim, Hyo-Jin; Park, Wan-Soo; Yoo, Ji-Hoon; Ko, Dae-Hong; Kim, Tae-Woo; Kim, Sang-Kuk; Kim, Jae-Gyu; Yun, Jacob; Kim, Ted; Lee, Jung-Hee; Shin, Chan-Soo; Lee, Jae-Hak; Seo, Kwang-Seok; Kim, Dae-Hyun | School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; Korea Advanced Nano Fab Center (KANC), Suwon, 16229, South Korea; School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; Department of Materials Science and Engineering, Yonsei University, Seoul, 03722, South Korea; School of Electrical Engineering, University of Ulsan, Ulsan, 44610, South Korea; QSI Inc, Cheonan, 31044, South Korea; QSI Inc, Cheonan, 31044, South Korea; QSI Inc, Cheonan, 31044, South Korea; QSI Inc, Cheonan, 31044, South Korea; School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; Korea Advanced Nano Fab Center (KANC), Suwon, 16229, South Korea; School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; Korea Advanced Nano Fab Center (KANC), Suwon, 16229, South Korea; School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea | 37016357200; 57202871742; 57189694750; 57221766125; 57825819100; 57202516002; 57222957219; 57545572700; 16240618000; 57203495132; 57221604960; 59087926000; 57221602607; 57221599265; 57196140713; 57201540732; 55690077600; 58711653100; 57212363794 | dae-hyun.kim@ee.knu.ac.kr; | Electronics (Switzerland) | ELECTRONICS-SWITZ | N/A | 2079-9292 | 11 | 17 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;PHYSICS, APPLIED | 2022 | 2.9 | 44.7 | 0 | 2025-06-25 | 0 | Gate-All-Around (GAA); InGaAs; nanosheet (NS); selective regrowth | English | Final | 2022 | 10.3390/electronics11172744 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Review | Models of J/? photo-production reactions on the nucleon | The J/ iii photo-production reactions on the nucleon can provide information on the roles of gluons in determining the J/ iii-nucleon (J/ iii-N) interactions and the structure of the nucleon. The information on the J/iii-N interactions is needed to test lattice QCD (LQCD) calculations and to understand the nucleon resonances such as N*(Pc) recently reported by the LHCb Collaboration. In addition, it is also needed to investigate the production of nuclei with hidden charms and to extract the gluon distributions in nuclei. The main purpose of this article is to review six models of the gamma + p-* J/ iii + p reaction which have been and can be applied to analyze the data from Thomas Jefferson National Accelerator Facility (JLab). The formulae for each model are given and used to obtain the results to show the extent to which the available data can be described. The models presented include the Pomeron-exchange model of Donnachie and Landshoff (Pom-DL) and its extensions to include J/ iii-N potentials extracted from LQCD (Pom-pot) and to also use the constituent quark model (CQM) to account for the quark substructure of J/ iii (Pom-CQM). The other three models are developed from applying the perturbative QCD approach to calculate the two-gluon exchange using the generalized parton distribution (GPD) of the nucleon (GP D- based), two-and three-gluon exchanges using the parton distribution of the nucleon (2g+3g), and the exchanges of scalar (0++) and tensor (2++) glueballs within the holographic formulation (holog). The results of investigating the excitation of the nucleon resonances N*(Pc) in the gamma + p-* J/ iii + p reactions are also given. We demonstrate that the differences between these six models can be unambiguously distinguished and the N* can be better studied by using the forthcoming JLab data at large |t| and at energies very near the J/ iii production threshold. Possible improvements of the considered models are discussed. | Lee, T.

| ○ | ○ | Article | Photo-neutron cross-section of ⁿatGd in the bremsstrahlung end-point energies of 12-16 MeV and 60-70 MeV | The spectrum-averaged cross-sections of Gd-nat(gamma, xn)Gd-159,Gd-153 reactions induced by the bremsstrahlung end-point energies of 12, 14, 16. 60, 65, and 70 MeV were measured by activation and off-line gamma-ray spectrometric technique using the 20 MeV electron linac (ELBE) at HZDR, Dresden, Germany, and 100 MeV electron linac at Pohang Accelerator Laboratory, Korea. The TALYS 1.9 code was also used to calculate the theoretical Gd-nat(gamma, xn)Gd-159,Gd-153 reaction cross-sections as a function of photon energy. The spectrum-averaged values at various end-point energies were calculated from the literature data as well as theoretical values based on the TALYS 1.9 code, which is for mono-energetic photons. They were found to be in good agreement with the flux-weighted values of the current experimental data. It was also observed that the experimental and theoretical cross-sections increase from the threshold values to a certain energy, at which point another reaction channel opens, indicating the role of excitation energy. Individual reaction cross-sections decrease after a certain value as bremsstrahlung energy increases due to the opening of other reactions, indicating energy shearing among the different reaction channels. | Naik, H.; Kim, G.

| ○ | ○ | Article | Precipitation of Ferrous Oxalate from Ferrous Ammonium Sulfate in Oxalic Acid Solution | A kinetic study was conducted experimentally for the precipitation of ferrous oxalate. The ferrous oxalate, in the form of dihydrate (FeC2O4 center dot 2H(2)O), was produced by the acidic dissolution of ferrous ammonium sulfate (Fe(NH4)(2)(SO4)(2)) in an aqueous solution of oxalic acid, and then precipitated by nucleation and particle growth from supersaturated solution. The effect of the concentration of ferrous ammonium sulfate and oxalic acid as raw materials was investigated on the kinetics of the ferrous oxalate precipitation. Temperature was kept constant at 25 degrees C. The surface morphology, atomic compositions, and crystal phase were characterized for the ferrous oxalate precipitate collected. As the initial concentration of ferrous ammonium sulfate increased, the initial precipitation of ferrous oxalate occurred faster. The concentration of oxalic acid did not significantly affect the rate of precipitation of ferrous oxalate. The experimental behavior of ferrous oxalate precipitation was modeled with first-order models of reaction kinetics. | Lee, Su In; Kim, Hye Rim; Park, Jae Kwan; Oh, Wonzin; Kim, Jeongju; Kim, Chorong; Lee, Junghyun; Kim, Ki-Chul; Lee, Byung-Chul | Hannam Univ, Dept Chem Engn, Daejeon 34054, South Korea; Kyungpook Natl Univ, Res Inst Adv Energy Technol, Daegu 41566, South Korea; KHNP Cent Res Inst, Daejeon 34101, South Korea; KEPCO KPS, Busan 46036, South Korea | 57606498400; 57607571600; 57610230000; 7201606916; 57471049800; 56158823200; 58132648800; 57209366711; 57203795455 | wonzin@knu.ac.kr;bclee@hnu.kr; | PROCESSES | PROCESSES | 2227-9717 | 10 | 11 | SCIE | ENGINEERING, CHEMICAL | 2022 | 3.5 | 44.7 | 0.76 | 2025-06-25 | 9 | 9 | precipitation; ferrous oxalate; ferrous ammonium sulfate; oxalic acid; kinetics; chemical decontamination | DISSOLUTION; MAGNETITE | chemical decontamination; ferrous ammonium sulfate; ferrous oxalate; kinetics; oxalic acid; precipitation | Morphology; Nitrogen compounds; Oxalic acid; Precipitation (chemical); Reaction kinetics; Sulfur compounds; Surface morphology; Acidic dissolution; Atomic compositions; Atomic crystals; Chemical decontamination; Dihydrates; Kinetic study; Nucleation growth; Oxalic acid solution; Particle growth; Supersaturated solutions; Kinetics | English | 2022 | 2022-11 | 10.3390/pr10112420 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | PUF-PSS: A Physically Secure Privacy-Preserving Scheme Using PUF for IoMT-Enabled TMIS | With the development of telecare medical information system (TMIS), doctors and patients are able to access useful medical services via 5G wireless communications without visiting the hospital in person. Unfortunately, TMIS should have the essential security properties, such as anonymity, mutual authentication, and privacy, since the patient's data is transmitted via a public channel. Moreover, the sensing devices deployed in TMIS are resource-limited in terms of communication and computational costs. Thus, we design a physically secure privacy-preserving scheme using physical unclonable functions (PUF) in TMIS, called PUF-PSS to resolve the security requirements and efficiency of the existing related schemes. PUF-PSS prevents the security threats and also guarantees anonymity, key freshness, and authentication. We evaluate the security of PUF-PSS by performing formal and informal security analyses, including AVISPA implementation and ROR oracle model. We perform the test bed experiments utilizing well-known MIRACL based on a Raspberry PI 4 and compare the communication and computational costs of PUF-PSS with the previous schemes for TMIS. Consequently, PUF-PSS guarantees better efficiency and security than previous schemes and can be applied to TMIS environments. | Yu, Sungjin; Park, Kisung | Elect & Telecommun Res Inst, Daejeon 34129, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea | ; Park, Kisung/KIG-3849-2024 | 57203974524; 57194833768 | ks.park@etri.re.kr; | ELECTRONICS | ELECTRONICS-SWITZ | 2079-9292 | 11 | 19 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;PHYSICS, APPLIED | 2022 | 2.9 | 44.7 | 0.47 | 2025-06-25 | 4 | 6 | telecare medical information systems; healthcare; physical unclonable function; privacy-preserving; security protocol | USER AUTHENTICATION SCHEME; KEY AGREEMENT; LIGHTWEIGHT AUTHENTICATION; EXCHANGE; PROTECTION; PROTOCOL | healthcare; physical unclonable function; privacy-preserving; security protocol; telecare medical information systems | English | 2022 | 2022-10 | 10.3390/electronics11193081 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
