| ○ | ○ | Article | NMR analysis of structural geometry and molecular dynamics in perovskite-type N(CH3)4CdBr3 crystal near high-temperature phase transition | The NMR chemical shifts, linewidths, spin-lattice relaxation times in the rotating system T-1 rho, and spin-lattice relaxation times in the laboratory system T-1 were evaluated for the perovskite-type N(CH3)(4)CdBr3 crystal, aiming to understand the changes in the structural geometry and molecular dynamics from phase I to phase II. From the temperature-dependence of the H-1, C-13, N-14, and Cd-113 NMR chemical shifts, the structural geometry underwent a continuous change, without anomalous changes around (T-C = 390 K). However, the linewidths in phase I were narrower than those in phase II, indicating that the motional averaging effects were caused by the rapid rotation of the N(CH3)(4) group. Sudden changes in T-1 and T-1 rho were observed near T-C, for which the activation energy E-a in phase I was approximately 12 times larger than that in phase II; the small E-a values in phase II indicate a large degree of freedom for the methyl group and CdBr6 octahedra, whereas the large E-a in phase I was primarily attributed to the overall N(CH3)(4) and the Cd-113 in the CdBr6 groups. Consequently, the phase transition mechanisms of N(CH3)(4)CdBr3 are related to reorientation of the N(CH3)(4) group and the arrangement of the CdBr6 groups. | Lim, Ae Ran; Kim, Sun Ha | Jeonju Univ, Grad Sch Carbon Convergence Engn, Jeonju 55069, South Korea; Jeonju Univ, Dept Sci Educ, Jeonju 55069, South Korea; Seoul Western Ctr, Korea Basic Sci Inst, Seoul 03759, South Korea; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea | 7202659025; 54386953600 | aeranlim@hanmail.net; | RSC ADVANCES | RSC ADV | 2046-2069 | 14 | 19 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2024 | 4.6 | 31.2 | 0.29 | 2025-05-07 | 1 | 1 | Activation energy; Bromine compounds; Cadmium compounds; Chemical shift; Degrees of freedom (mechanics); Geometry; Molecular dynamics; Perovskite; Relaxation time; High temperature phase transitions; In-phase; NMR analysis; NMR chemical shifts; Perovskite type; Phase I; Phase II; Rotating systems; Spin lattice relaxation time; Structural geometry; Temperature distribution | English | 2024 | 2024-04-22 | 10.1039/d4ra02220c | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||||
| ○ | ○ | Article | Ultrasmall cerium oxide nanoparticles as highly sensitive X-ray contrast agents and their antioxidant effect | Owing to their theranostic properties, cerium oxide (CeO2) nanoparticles have attracted considerable attention for their key applications in nanomedicine. In this study, ultrasmall CeO2 nanoparticles (particle diameter = 1-3 nm) as X-ray contrast agents with an antioxidant effect were investigated for the first time. The nanoparticles were coated with hydrophilic and biocompatible poly(acrylic acid) (PAA) and poly(acrylic acid-co-maleic acid) (PAAMA) to ensure satisfactory colloidal stability in aqueous media and low cellular toxicity. The synthesized nanoparticles were characterized using high-resolution transmission electron microscopy, X-ray diffraction, Fourier transform-infrared spectroscopy, thermogravimetric analysis, dynamic light scattering, cell viability assay, photoluminescence spectroscopy, and X-ray computed tomography (CT). Their potential as X-ray contrast agents was demonstrated by measuring phantom images and in vivo CT images in mice injected intravenously and intraperitoneally. The X-ray attenuation of these nanoparticles was greater than that of the commercial X-ray contrast agent Ultravist and those of larger CeO2 nanoparticles reported previously. In addition, they exhibited an antioxidant effect for the removal of hydrogen peroxide. The results confirmed that the PAA- and PAAMA-coated ultrasmall CeO2 nanoparticles demonstrate potential as highly sensitive radioprotective or theranostic X-ray contrast agents.

| ○ | ○ | Article | Scaling of the linear viscoelasticity of entangled poly(ethylene oxide) aqueous solutions | The dynamic modulus of polymer solutions and melts can be expressed as a universal function of reduced frequency when the modulus is scaled by a characteristic value according to the scaling theory of polymer physics. Although the plot of the scaled modulus as a function of the scaled frequency supports the theory, it suffers from considerable scattered distribution of data points around the hypothetical master curve. Compared with the master curve of the time-temperature superposition (TTS) of polymer melts, the master curve of polymer solutions has poor quality. Furthermore, the scale factors of polymer solutions may not show a clear dependency on molecular weight and concentrations. Experimental errors and molecular weight distribution appear to enhance the inaccuracy of the master curve. Therefore, we apply a global optimization for the superposition of the viscoelastic data of polymer solutions with various molecular weights and concentrations. The global optimization resulted in the superposition of data as accurate as that of TTS. Furthermore, the numerically determined shift factors, which were relative scale factors, showed clear dependences on molecular weight and concentrations. We compared our global optimization with previous scaling methodologies. | Lee, Heeyeol; Lee, Junghaeng; Ahn, Hye-Jin; Hwang, Wook Ryol; Cho, Kwang Soo | Kyungpook Natl Univ, Dept Polymer Sci & Engn, Daegu, South Korea; Gyeongsang Natl Univ, Sch Mech Engn, Jinju, South Korea | 59447648100; 57198781113; 56808653600; 10641313400; 56316379300 | polphy@knu.ac.kr; | JOURNAL OF RHEOLOGY | J RHEOL | 0148-6055 | 1520-8516 | 68 | 4 | SCIE | MECHANICS | 2024 | 3.2 | 31.3 | 0 | 2025-05-07 | 0 | 0 | scaling analysis; superposition principle; poly(ethylene oxide) aqueous solutions; molecular weight distribution (MWD); linear viscoelasticity | POLYMER-SOLUTIONS; SPECTRUM | linear viscoelasticity; molecular weight distribution (MWD); poly(ethylene oxide) aqueous solutions; scaling analysis; superposition principle | Ethylene; Global optimization; Polyethylene oxides; Polymer melts; Viscoelasticity; Global optimisation; Linear viscoelasticity; Master-curve; Molecular weight distribution; Molecular-weight distributions; Poly(ethylene oxide) aqueous solution; Poly(ethylene) oxide; Scaling analysis; Superposition principle; Time temperature superposition; Molecular weight distribution | English | 2024 | 2024-07 | 10.1122/8.0000757 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Association between heart rate variability metrics from a smartwatch and self-reported depression and anxiety symptoms: a four-week longitudinal study | Background: Elucidating the association between heart rate variability (HRV) metrics obtained through non-invasive methods and mental health symptoms could provide an accessible approach to mental health monitoring. This study explores the correlation between HRV, estimated using photoplethysmography (PPG) signals, and self-reported symptoms of depression and anxiety. Methods: A 4-week longitudinal study was conducted among 47 participants. Time–domain and frequency–domain HRV metrics were derived from PPG signals collected via smartwatches. Mental health symptoms were evaluated using the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) at baseline, week 2, and week 4. Results: Among the investigated HRV metrics, RMSSD, SDNN, SDSD, LF, and the LF/HF ratio were significantly associated with the PHQ-9 score, although the number of significant correlations was relatively small. Furthermore, only SDNN, SDSD and LF showed significant correlations with the GAD-7 score. All HRV metrics showed negative correlations with self-reported clinical symptoms. Conclusions: Our findings indicate the potential of PPG-derived HRV metrics in monitoring mental health, thereby providing a foundation for further research. Notably, parasympathetically biased HRV metrics showed weaker correlations with depression and anxiety scores. Future studies should validate these findings in clinically diagnosed patients.

| ○ | ○ | Article | Dietary 7,10-dihydroxy-8(E)-octadecenoic acid reduces fat accumulation and prevents hyperglycemia and hyperlipidemia in diabetic/obese KK-Ay mice | 7,10-Dihydroxy-8(E)-octadecenoic acid (DOD) is a dihydroxy fatty acid produced by Pseudomonas aeruginosa PR3 from oleic acid. Present study investigated preventive effects of dietary DOD on obesity, hyperlipidemia and hyperglycemia in diabetic/obese KK-A(y) mice. After one week of acclimation, mice (5-week-old) were divided three groups fed with AIN-93G-based high fat diet (20% fat, w/w) as follows; Control group: 3% soybean oil + 17% lard, DOD 1% group: 3% soybean oil + 16% lard +1% DOD, DOD 2% group: 3% soybean oil + 15% lard + 2% DOD. Four weeks feeding with 1% and 2% DOD diets suppressed body weight gain and visceral fat accumulation, and improved blood glucose and serum lipids levels as well as hepatic lipid accumulation compared to control group. RT-PCR analysis revealed no changes were observed in mRNA of adiponectin (Adipoq) and proinflammatory TNF-alpha (Tnfa) and MCP-1 (Ccl2), but a decreasing trend in leptin mRNA expression in mesenteric white adipose tissue (WAT), suggesting that suppressed fat accumulation by DOD contribute to prevention of over production of leptin. We also observed a reduction of mRNA expression of hepatic insulin-target gluconeogenic enzymes such as PEPCK and G6Pase and the transcription factor sterol regulatory element-binding protein-1. These results showed that dietary DOD is effective to improve glucose and lipid metabolism in KK-A(y )mice. The present study provides new insights showing potential use of dihydroxy fatty acids as functional lipids. | Beppu, Fumiaki; Fuji, Shota; Kim, Hak-Ryul; Hou, Ching T.; Miyashita, Kazuo; Hosokawa, Masashi | Hokkaido Univ, Fac Fisheries Sci, Hakodate, Hokkaido, Japan; Kyungpook Natl Univ, Daegu, South Korea; USDA, Natl Ctr Agr Utilizat Res, Agr Res Serv, Peoria, IL USA | ; Hosokawa, Masashi/C-3024-2008; BEPPU, Fumiaki/O-1986-2014 | 6506604528; 59348914700; 57191717289; 7202210071; 57541565100; 7202009871 | hoso@fish.hokudai.ac.jp; | BIOCATALYSIS AND AGRICULTURAL BIOTECHNOLOGY | BIOCATAL AGR BIOTECH | 1878-8181 | 61 | ESCI | BIOTECHNOLOGY & APPLIED MICROBIOLOGY | 2024 | 3.8 | 31.4 | 0 | 2025-05-07 | 1 | 1 | 10-Dihydroxy-8( E )-octadecenoic acid; Hydroxy fatty acids; Obesity; Hyperglycemia; Hyperlipidemia | ELEMENT-BINDING PROTEIN-1; OLEIC-ACID; GENE-EXPRESSION; ANTIBACTERIAL ACTIVITY; INSULIN-RESISTANCE; LINOLEIC-ACID; BIOCONVERSION; INTERMEDIATE; ACTIVATION; COMPOUND | 7,10-Dihydroxy-8(E)-octadecenoic acid; Hydroxy fatty acids; Hyperglycemia; Hyperlipidemia; Obesity | English | 2024 | 2024-10 | 10.1016/j.bcab.2024.103390 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Facial emotion-recognition deficits in patients with schizophrenia and unaffected first-degree relatives | Introduction This study aimed to determine trait- and state-dependent markers of schizophrenia by investigating facial emotion-recognition (FER) deficits in remitted patients with schizophrenia and their first-degree relatives (FR).Methods Three groups were included: the Schizophrenia group (n=66), their unaffected FR group (n=40), and healthy controls (n=50) who were matched for age, sex, and years of education. A facial-labeling task was used to examine FER deficits using the following eight standardized expressions: happy, fearful, disgusted, angry, sad, contemptuous, surprised, and neutral.Results There was a poorer accuracy in the recognition of sadness and anger in the Schizophrenia group as well as in contempt in both the Schizophrenia and FR groups compared with healthy controls. The response times for the recognition of contempt, sadness, and neutral emotion were delayed in the Schizophrenia group and those for fear were delayed in the Schizophrenia and FR groups compared with healthy controls.Conclusion Concerning the accuracy in FER, sadness and anger can be considered state-dependent markers of remitted schizophrenia, and contempt is a trait-dependent marker of schizophrenia. Similarly, for response times in FER, contempt, sadness, and neutral emotion can be considered state-dependent markers of remitted schizophrenia, while fear is considered a trait-dependent marker of schizophrenia. These findings may contribute to the early diagnosis of schizophrenia and the development of relevant therapeutic interventions. | Bae, Minjae; Cho, Jihyun; Won, Seunghee | Kyungpook Natl Univ, Sch Med, Dept Psychiat, Daegu, South Korea; Gyeongsan Joongang Hosp, Dept Psychiat, Gyongsan, Gyeongbuk, South Korea; Kyungpook Natl Univ Hosp, Dept Psychiat, Daegu, South Korea | 59001123700; 59001897600; 35278955600 | wonsh864@knu.ac.kr; | FRONTIERS IN PSYCHIATRY | FRONT PSYCHIATRY | 1664-0640 | 15 | SCIE;SSCI | PSYCHIATRY | 2024 | 3.2 | 31.4 | 0.72 | 2025-04-16 | 2 | 1 | schizophrenia; emotion recognition; facial emotion; 1st degree relatives; high-risk group | CLINICAL HIGH-RISK; RATING-SCALE; PERCEPTION; INDIVIDUALS; RELIABILITY; IDENTIFICATION; EXPRESSIONS; SIBLINGS | 1st degree relatives; emotion recognition; facial emotion; high-risk group; schizophrenia | antidepressant agent; benzodiazepine; beta adrenergic receptor blocking agent; cholinergic receptor blocking agent; adult; anger; Article; Beck Depression Inventory; cognition; controlled study; DSM-5; emotion; facial expression; facial recognition; fear; female; first-degree relative; Hamilton Depression Rating Scale; human; major clinical study; male; mental disease; Montreal cognitive assessment; participation; Positive and Negative Syndrome Scale; reaction time; sadness; schizophrenia | English | 2024 | 2024-04-12 | 10.3389/fpsyt.2024.1373288 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Neural correlates of thought-action fusion and their associations with rumination in patients with major depressive disorder | Thought-action fusion (TAF) is the metacognitive belief that the power of thoughts can have real-life consequences, often inducing unpleasant inner experiences and recruiting coping strategies such as rumination. Therefore, this study aimed to investigate the neural correlates of TAF and their associations with rumination in depression. A total of 37 patients with major depressive disorder (MDD) and 37 healthy controls (HCs) underwent functional magnetic resonance imaging with a TAF induction task and psychological assessments. In the TAF induction task, participants were asked to read the name of a close person (CP) or neutral person (NP) in association with negative (Neg) TAF and neutral (Neu) control statements. In this study, our TAF induction task activated brain regions, including the salient and default-mode networks, in the MDD and HC groups. However, along with higher likelihood TAF and rumination, behavioral data showed less negative feelings and longer reaction times under the NegCP condition in the MDD group compared with the HC group. Furthermore, in the MDD group, significantly higher activation in the bilateral caudate nuclei, left inferior frontal gyrus/anterior insula, putamen, and inferior parietal lobule under the NegCP condition was positively correlated with TAF and reflection. These findings suggest that during the TAF task, patients with MDD may activate different brain areas associated with the maintenance of high stimulus saliency and habit formation, which are important neural correlates linking TAF and rumination in depression. | Lee, Sang Won; Kim, Seungho; Lee, Hansol; Chang, Yongmin; Lee, Seung Jae | Kyungpook Natl Univ, Chilgok Hosp, Dept Psychiat, Daegu, South Korea; Kyungpook Natl Univ, Dept Psychiat, Sch Med, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Dept Med & Biol Engn, Taegu, South Korea; Kyungpook Natl Univ, Dept Mol Med, Sch Med, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ Hosp, Dept Radiol, Taegu, South Korea; Kyungpook Natl Univ Hosp, Dept Psychiat, Taegu, South Korea | Lee, Seung/AAI-1191-2020 | 55820414800; 57218284791; 59299461900; 7501840633; 58509400200 | ychang@knu.ac.kr;jayleemd@knu.ac.kr; | JOURNAL OF PSYCHIATRIC RESEARCH | J PSYCHIATR RES | 0022-3956 | 1879-1379 | 180 | SCIE;SSCI | PSYCHIATRY | 2024 | 3.2 | 31.4 | 0.57 | 2025-05-07 | 1 | 1 | fMRI; Transdiagnostic; Salience network; Response inhibition; Caudate; Insula | OBSESSIVE-COMPULSIVE DISORDER; DEFAULT-MODE; RELIABILITY; SUPPRESSION; EMOTION; ANXIETY; VERSION; SCALE | Caudate; fMRI; Insula; Response inhibition; Salience network; Transdiagnostic | Adult; Brain; Default Mode Network; Depressive Disorder, Major; Female; Humans; Magnetic Resonance Imaging; Male; Middle Aged; Rumination, Cognitive; Thinking; Young Adult; amfebutamone; benzodiazepine derivative; desvenlafaxine; escitalopram; venlafaxine; adult; anterior insula; Article; brain region; caudate nucleus; controlled study; default mode network; electroencephalogram; female; functional magnetic resonance imaging; human; inferior frontal gyrus; inferior parietal lobule; major clinical study; major depression; male; metacognition; psychologic assessment; psychological aspect; putamen; reaction time; rumination; salience network; thought action fusion; brain; cognitive rumination; diagnostic imaging; middle aged; nuclear magnetic resonance imaging; pathophysiology; physiology; thinking; young adult | English | 2024 | 2024-12 | 10.1016/j.jpsychires.2024.10.005 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

The main findings of this study are tested by using multivalued functions,sectorial operators, fractional derivatives, and the fixed point theorem. To begin,the existence of mild solutions is established and verified primarily by using avery well multivalued fixed point theorem and the characteristics of generalizedClarke subdifferential problems. Furthermore, we get a finding on the existenceof optimal control for the presented control system under particular reasonableconditions. After that, we will move on to the time optimal control results forthe given system.

In this letter, we present a novel approach for remote heart rate measurement leveraging a Spatial-Temporal SwiftFormer architecture (STSPhys). Our model addresses the limitations of existing methods that rely heavily on 3D CNNs or 3D visual transformers, which often suffer from increased parameters and potential instability during training. By integrating both spatial and temporal information from facial video data, STSPhys achieves robust and accurate heart rate estimation. Additionally, we introduce a hybrid loss function that integrates constraints from both the time and frequency domains, further enhancing the model's accuracy. Experimental results demonstrate that STSPhys significantly outperforms existing state-of-the-art methods on intra-dataset and cross-dataset tests, achieving superior performance with fewer parameters and lower computational complexity. © 1994-2012 IEEE. | Kim, Hyunduk; Lee, Sang-Heon; Sohn, Myoung-Kyu; Kim, Jungkwang; Park, Hyeyoung | Daegu Gyeongbuk Institute of Science and Technology, Division of Automotive Technology, Daegu, 42988, South Korea, Kyungpook National University, School of Computer Science and Engineering, Daegu, 37224, South Korea; Daegu Gyeongbuk Institute of Science and Technology, Division of Automotive Technology, Daegu, 42988, South Korea; Daegu Gyeongbuk Institute of Science and Technology, Division of Automotive Technology, Daegu, 42988, South Korea; Daegu Gyeongbuk Institute of Science and Technology, Division of Automotive Technology, Daegu, 42988, South Korea; Kyungpook National University, School of Computer Science and Engineering, Daegu, 37224, South Korea | 55579821400; 57192514407; 55545956400; 59496729000; 55713613500 | IEEE Signal Processing Letters | IEEE SIGNAL PROC LET | 1070-9908 | 1558-2361 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC | 2024 | 3.9 | 31.6 | 0 | 2025-05-07 | 0 | rHR; RPPG; spatial-temporal visual trasnformer | Frequency estimation; Photoplethysmography; Physiological models; Video analysis; Video recording; Heart activities; Heart-rate; Parameter instability; Physiological signals; Rate estimation; Rate measurements; RHR; RPPG; Spatial temporals; Spatial-temporal visual trasnformer; Heart | English | Article in press | 2024 | 10.1109/lsp.2024.3522854 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
