Intelligence develops according to the environment that influences an individual. Then it is this intelligence that makes the difference between one individual and another. This intelligence is important in life because basically humans cannot live alone. Humans are social creatures who are always in contact with other people. Relationships with people around, of course, communicate with each other which is the basis for interaction between individuals because basically communication is very intertwined with interpersonal relationships. However, it is unfortunate that children's interpersonal intelligence is still very low, due to a lack of interaction with peers, teachers, and the environment, so they feel isolated. People who are belittled have negative characteristics such as being aggressive, difficult to cooperate with, and a lack of sympathy and empathy. That way it is necessary to do a research in order to improve and realize preventive efforts. The purpose of this study was to implement the Science, Environment, Technology, Society (SETS) model for the development of interpersonal intelligence in grade IV students in science learning. The research method used in this study was quantitative with a pre-experimental approach with fourth grade students at Balerejo State Elementary School. Based on the results of the research and discussion, students must establish good relationships with other people, have a sense of empathy and sympathy and be able to maintain good friendships with friends. That way, it is highly recommended for teachers to develop interpersonal intelligence by applying model sets.

Published: July 2024

Nocturnal Leg Cramps (NLC) are involuntary lower limb contractions that are painful and occur during long rest periods. Magnesium is thought to have potential in the treatment of NLC as one of the precipitating factors of NLC is low levels of certain minerals, such as magnesium deficiency. This study aimed to assess the effectiveness of magnesium adjunctive therapy in reducing cramping pain intensity in patients with NLC. This study was a randomized clinical trial, open-label, controlled group that was followed up for 2 weeks. 30 subjects who have been diagnosed with the NLC short-form adaptation of ICSD 2005 were divided into 2 groups; (1) the intervention group who was given standard NLC therapy (calcium and gabapentin) with additional therapy of magnesium citrate 100 mg (Hi-Mg100) one tablet a day, (2) the control group who was only given standard NLC therapy. NLC cramping pain was measured using the Numeric Rating Scale (NRS) before the administration of therapy (baseline) and at week 2 after therapy. The results obtained were the addition of magnesium to standard therapy provided a significant reduction in cramping pain intensity between before and after treatment based on the Wilcoxon signed rank test (p=0.000). However, there was no statistically significant difference effect between the two therapy groups based on the Mann-Whitney test (p=0.073). In conclusion, magnesium adjunctive therapy was not significantly more effective in reducing cramping pain than standard drug therapy in patients with NLC.

Published: July 2024

Nanogels (Ngl) have emerged as one of the most prominent and convenient systems to act as site-specific drug delivery systems and antimicrobial agents for a varied range of diseases. Super absorbent silver incorporated gelatine-based nanogel (Ngl) grafted with acrylic acid (AAc) (gelatin-grafted-acrylic acid) (SGlAsTC) was synthesized by the chemical polymerization method for use as antimicrobial agents and prospective drug delivery matrices. The nanogel was synthesized employing N, N, Methylene bisacrylamide as a crosslinker and TEMED (N, N, N,N-Tetramethylethylenediamine) as a surfactant. The thus obtained Ngl was characterized by particle size analysis (DLS), FT-R, XRD, EDX, FESEM, and DSC to get evidence of nanogel synthesis. FTIR analysis confirmed the crosslinking reaction with AAc of Ngl, and the spherical morphology studies of SGlAsTC were confirmed by the FESEM image, which showed a sphere-like morphology with porous and crumpled particles. A swelling study was carried out at different pHs (2.2, 4.2, 6.5, 7.4, and 8.2) and at two different temperatures (at 25°C and 37°C) to evaluate the water absorption ability of the synthesized Ngl. The synthesized Ngl was subjected to antimicrobial studies against four different bacteria, exhibiting an exceptional inhibition zone for SGlAsTC against Pseudomonas aeruginosa. Excellent results were observed for SGlAsTC against the bacteria compared to the positive control (azithromycin). The results could be attributed to gelatin molecules that facilitated the absorption of the silver-incorporated AAc chains into the bacterial cell wall and speeded up the destruction of the cell cytoplasm

Published: July 2024

In this work, a series of planar anode billes for a solid oxide fuel cell based on NiO/Ce0.8Gd0.2O2 (NiO/GDC) was fabricated using the microdroplet 3D printing method with a pneumatic metering valve. The porosity and shrinkage coefficient during sintering of the anode billes, depending on the method of fabrication, have been investigated.
Anode billes were reduced in a hydrogen flow, and the effect of printing parameters on the morphological, structural, and electrochemical characteristics of NiO/Ce0.8Gd0.2O2 cermet was studied. The use of 3D printing was found to increase the porosity of the Ni/GDC composite from 7 to 23% as compared to that of the sample prepared by means of casting, while the value of electrical conductivity, (2.82 ± 0.06)·103 S/cm, remains high.
Influence of the nature of a heterogeneous dopant on the transport and thermodynamic properties of composites based on n-methyl-n-butyl-piperidinium tetrafluoroborate

Published: July 2024

Composite solid electrolytes based on n-methyl-n-butyl-piperidinium tetrafluoroborate [(CH3)(C4H9)C5H10N]BF4–A (where A is γ-Al2O3, SiO2) were synthesized and their thermal and electrically conductive properties have been studied. It was found that the conductivity of the [C10H22N]BF4–Al2O3 composites passes through a maximum at x~0.9 and reaches a value of 4.6·10-4 S/cm at 130оC for the 0.1[C10H22N]BF4–0.9Al2O3 composite. The absence of a thermal effect at the melting temperature of the ionic salt, which indicates a high ionic conductivity, indicates that at x ≥ 0.9, n-methyl-n-butyl-piperidinium tetrafluoroborate is in the amorphous state and ion transfer occurs along the ionic salt/oxide phase boundary. In the case of [C10H22N]BF4 – SiO2 composites, the effect of a heterogeneous dopant on ion transport is less significant and the conductivity is due to the ionic salt of the additive present in the pores.

The involvement of inflammation, disturbances of glutamate metabolism and oxidative stress in the pathogenesis of schizophrenia and affective disorders has been proven by numerous studies. It seems relevant to assess the role of these systems in the development of prodromal stages of schizophrenia in juvenile patients with depression. The aim of this study was to investigate the connection between markers of inflammation, energy and glutamate metabolism, and antioxidant defense with the clinical features of patients with adolescent depression. 74 males aged 16–25 years with a first depressive episode (F32.1–2, F32.38, F32.8) were observed: 32 subjects with attenuated positive symptoms, 22 persons with attenuated negative symptoms, 20 individuals without attenuated schizophrenia symptoms. The control group included 57 mentally healthy adults aged 16–25 years. The activity of leukocyte elastase and α1-proteinase inhibitor, the level of autoantibodies to S100B and myelin basic protein in plasma and the activity of cytochrome c-oxidase, glutamate dehydrogenase, glutathione reductase and glutathione-S-transferase in platelets were determined. Within each clinical group, differences in the profiles of immunological and biochemical parameters were identified. Division of patients into clusters according to all biological parameters showed different level of inflammation and changes of glutamate metabolism and antioxidant defense related to the features of psychopathological symptoms. The results confirm the connection of the studied metabolic systems and their different involvement to the development of adolescent depression with different psychopathological structure, which is important to assess the role of these systems in the trajectory of the disease and early therapeutic correction.

Published: July 2024

The Meetings, Incentives, Conferences, and Exhibitions (MICE) industry, particularly within the domain of music concerts, stands poised for significant enhancement in Indonesia. It is worth noting that Indonesia has successfully hosted numerous international music concerts; however, there is still considerable room for growth compared to other ASEAN countries. This study employs theory synthesis to achieve conceptual integration as a research framework construct by combining the FoMO phenomenon, which is currently prevalent due to the rise of social networking sites (SNS), with different policies facilitating music concerts in Indonesia. This review study aims to achieve its research objectives and establish that the Fear of Missing Out (FoMO) phenomenon can significantly enhance music performance ticket sales. This is achieved by constructing the FoMO trait and the Bergen Facebook Addiction Scale, then classifying products according to each concert theme, whether virtual or physical. By capitalizing on the ubiquitous presence of social networking sites (SNS) and the heightened Fear of Missing Out (FoMO) phenomenon post-COVID-19, we anticipate significant improvements. This conceptual study can serve as a valuable resource for enhancing research on the optimization of music concerts, which is also an area that is still underexplored, particularly in Indonesia.

Virtual Reality (VR) has grown rapidly since the COVID-19 pandemic and continues to grow even after the pandemic is over. In the tourism industry, VR applications are often used in the tourism process to promote destinations and attract tourists to visit. Starting from the quality of VR applications, tourists will intend to use VR applications if these applications have good quality. For this reason, by assessing VR quality and incorporating it into TAM, this study aims to explore the adoption of VR applications in the tourism sector. This study included 400 VR users as participants. Using the partial least square structural equational model (PLS-SEM), a number of hypotheses were assessed. The findings demonstrate that VR quality significantly influences all TAM constructs, including attitude and intention to use. Then, attitude is significantly influenced by perceived usefulness and ease of use. Finally, the intention to use is significantly influenced by attitude. These results indicate that VR quality that is useful and easy to use will determine the adoption of VR applications in tourism. This paper advances both theory and practice by explaining the importance of VR quality and TAM in the adoption of VR applications in tourism.

METHODS: In our study, 80 patients with HCC were analyzed retrospectively. According to the gold standard of postoperative pathology, the patients were divided into MVI positive group (n = 39) and MVI negative group (n = 41). we were to analyze the correlation between CEUS and MVI in combination with MFI, to identify independent risk factors for the occurrence of MVI positive, and to analyze the predictive efficacy of every independent risk factor and their combination in preoperative prediction of MVI. RESULTS: In our study, 80 patients were enrolled, including 39 patients in the MVI-positive group and 41 patients in the MVI-negative group, with a MVI-positive rate of 48.8%. By univariate analysis and multivariate analysis, it was found that there were statistically significant differences in enhancement range extension, start time of wash out and CEUS-MFI between the two groups, which were independent risk factors for MVI-positive. The combination of three independent risk factors is more effective than single one in predicting MVI of HCC. CONCLUSIONS: CEUS combined with MFI is feasible for the preoperative prediction of MVI in HCC, and can provides meaningful help for individualized clinical treatment.

Published: July 2024

BACKGROUND:

Although plateletpheresis donation is commonly accepted as a safe procedure, its influence on platelet function, coagulation system and fibrinolysis is not completely elucidated.

OBJECTIVES:

In this study, we tried to assess the effects of plateletpheresis on donor’s hemostasis system by measuring platelet activation, development of platelet-leukocyte aggregates, and coagulation activation.

STUDY DESIGN:

Prospective observational study.

METHODS:

We used flow cytometry to determine the levels of platelet-monocyte complexes (PMC) and platelet-neutrophil complexes (PNC). sP-selectin and prothrombin fragment (PF) 1 + 2 values were determined by ELISA.

RESULTS:

The PMC levels increased significantly seven days after apheresis in comparison with just after apheresis and 24 h after apheresis ( p < 0.05). The PNC levels increased significantly seven days after apheresis compared to immediately after apheresis ( p < 0.05). sP-selectin values decreased significantly immediately after apheresis ( p < 0.05). While sP-selectin values increased seven days after apheresis in comparison with immediately after apheresis and 24 h after apheresis, but there were not statistically significant differences for sP-selectin levels ( p > 0.05). PF1 + 2 levels decreased significantly immediately after apheresis compared to pre-apheresis ( p < 0.05) and increased 24 h after apheresis and seven days after apheresis, but these differences were not statistically significant.

CONCLUSION:

We concluded that plateletpheresis affects platelet activation but does not cause any change in coagulation activation.

BACKGROUND: The coronavirus disease (COVID-19) caused mandatory lockdowns across all organizations. Telework generated challenges in workflow due to limited organizational communication. OBJECTIVE: This study seeks to examine the impact of pre-, during, and post-COVID-19 on accounting professionals’ job behaviors and tests the moderating effect of organizational communication. Also, the study aims to provide implications for practitioners from the findings. METHODS: Survey data for accounting professionals working in North Carolina across COVID-19 time periods was collected to achieve a sample size of 333. Pairwise t-tests and hierarchical regression analyses were applied to test the hypotheses. RESULTS: The results suggest a statistically significant difference across certain time periods for job performance and turnover intentions but not job satisfaction. Furthermore, organizational communication moderates the relationship between post-COVID-19 and job performance and turnover intentions but not job satisfaction. CONCLUSIONS: Organizations should search for ways to enhance organizational communication to increase employee perceived job performance and decrease employee turnover intentions.

Published: July 2024

The artifacts affecting electroencephalographic (EEG) signals may undermine the correct interpretation of neural data that are used in a variety of applications spanning from diagnosis support systems to recreational brain-computer interfaces. Therefore, removing or - at least - reducing the noise content in respect to the actual brain activity data becomes of fundamental importance. However, manual removal of artifacts is not always applicable and appropriate, and sometimes the standard denoising techniques may encounter problems when dealing with noise frequency components overlapping with neural responses. In recent years, deep learning (DL) based denoising strategies have been developed to overcome these challenges and learn noise-related patterns to better discriminate actual EEG signals from artifact-related data. This study presents a novel DL-based EEG denoising model that leverages the prior knowledge on noise spectral features to adaptively compute optimal convolutional filters for multi-artifact noise removal. The proposed strategy is evaluated on a state-of-the-art benchmark dataset, namely EEGdenoiseNet, and achieves comparable to better performances in respect to other literature works considering both temporal and spectral metrics, providing a unique solution to remove muscle or ocular artifacts without needing a specific training on a particular artifact type.

Published: July 2024

Game-Based Learning (GBL) and its subset, Board Game-Based Learning (bGBL), are dynamic pedagogical approaches leveraging the immersive power of games to enrich the learning experience. bGBL is distinguished by its tactile and social dimensions, fostering interactive exploration, collaboration, and strategic thinking; however, its adoption is limited due to lack of preparation by teachers and educators and of pedagogical and instructional frameworks in scientific literature. Artificial intelligence (AI) tools have the potential to automate or assist instructional design, but carry significant open questions, including bias, lack of context sensitivity, privacy issues, and limited evidence. This study investigates ChatGPT as a tool for selecting board games for educational purposes, testing its reliability, accuracy, and context-sensitivity through comparison with human experts evaluation. Results show high internal consistency, whereas correlation analyses reveal moderate to high agreement with expert ratings. Contextual factors are shown to influence rankings, emphasizing the need to better understand both bGBL expert decision-making processes and AI limitations. This research provides a novel approach to bGBL, provides empirical evidence of the benefits of integrating AI into instructional design, and highlights current challenges and limitations in both AI and bGBL theory, paving the way for more effective and personalized educational experiences.

Published: July 2024

Background: Personalized dance-based movement therapies may improve cognitive and motor function in individuals with mild cognitive impairment (MCI), a precursor to Alzheimer’s disease. While age- and MCI-related deficits reduce individuals’ abilities to perform dance-like rhythmic movement sequences (RMS)—spatial and temporal modifications to movement—it remains unclear how individuals’ relationships to dance and music affect their ability to perform RMS. Objective: Characterize associations between RMS performance and music or dance relationships, as well as the ability to perceive rhythm and meter (rhythmic proficiency) in adults with and without MCI. Methods: We used wearable inertial sensors to evaluate the ability of 12 young adults (YA; age = 23.9±4.2 years; 9F), 26 older adults without MCI (OA; age = 68.1±8.5 years; 16F), and 18 adults with MCI (MCI; age = 70.8±6.2 years; 10F) to accurately perform spatial, temporal, and spatiotemporal RMS. To quantify self-reported music and dance relationships and rhythmic proficiency, we developed Music (MRQ) and Dance Relationship Questionnaires (DRQ), and a rhythm assessment (RA), respectively. We correlated MRQ, DRQ, and RA scores against RMS performance for each group separately. Results: The OA and YA groups exhibited better MRQ and RA scores than the MCI group (p < 0.006). Better MRQ and RA scores were associated with better temporal RMS performance for only the YA and OA groups (r2 = 0.18–0.41; p < 0.045). DRQ scores were not associated with RMS performance in any group. Conclusions: Cognitive deficits in adults with MCI likely limit the extent to which music relationships or rhythmic proficiency improve the ability to perform temporal aspects of movements performed during dance-based therapies.

Published: July 2024

Background: There are indications for sex-specific differences regarding the association between kallikrein-8 (KLK8) and cognitive impairment in early stages of Alzheimer’s disease for which KLK8 may be an early blood-based biomarker. These may be due to different levels of sex hormones. To correctly interpret KLK8 blood concentrations, sex-specific analyses are needed. Objective: The aim of our exploratory study was to investigate sex-specific differences in blood-based KLK8 in participants of the population-based Heinz Nixdorf Recall study with different cognitive status and the association between KLK8 and sex hormones. Methods: In 290 participants (45% women, 69.7±7.4 years (mean±SD)) we investigated sex-specific serum KLK8 differences between cognitively unimpaired (CU, 43%) and cognitively impaired (CI) participants and the association between KLK8 and dehydroepiandrosteronsulfate (DHEAS), estradiol and testosterone, using adjusted multiple linear regression. Results: The mean±SD KLK8 was similar for CU men (808.1±729.6 pg/ml) and women (795.9±577.7 pg/ml); adjusted mean-difference [95%-CI]: –95.3 [–324.1;133.5] pg/ml. KLK8 was lower in CI women (783.5±498.7 pg/ml) than men (1048.4±829 pg/ml); –261 [–493.1; –29] pg/ml. In men but not women, there was a weak indication for a positive slope between estradiol (11.9 [–0.4;24.3] pg/ml) and DHEAS (1.4 [–0.5;3.3] pg/ml) with KLK8, while testosterone had no impact. Conclusions: The results suggested a different role for KLK8 in the development of cognitive impairment in men and women, potentially influenced by sex hormones. To use blood KLK8 as an early biomarker, further research on hormonal regulation of KLK8 expression is needed as a part of the investigation of the KLK8 involvement in cognitive impairment and Alzheimer's disease pathology.
Progressive Supranuclear Palsy: Subcortical Tau Depositions Are Associated with Cortical Perfusion in Frontal and Limbic Regions

Published: July 2024

In progressive supranuclear palsy (PSP), subcortical tau and cortical perfusion can be assessed using the tracer [18F]PI-2620. We investigated if subcortical tau (globus pallidus internus, dentate nucleus) and frontal/limbic perfusion correlate in a cohort of 32 PSP patients. Tau in subcortical regions showed significant negative correlation with perfusion in limbic cortex. Perfusion in frontal regions was negatively associated with tau in both subcortical regions, but the significance threshold was only passed for the dentate nucleus. A reason could be a diaschisis-like phenomenon; that is, subcortical tau could lead to reduced connectivity to frontal regions and, thereby, to decreased perfusion.
