Objective: To assess the effectiveness and utility of a low-contrastvolume, coronary computed tomography angiography (CCTA) protocol that leverages a lower tube peak voltage (80 kVp) compared to the conventionally employed 120 kVp in patients referred for diagnostic coronary CT angiography.
Materials and Methods: 120 patients (60 males, between 23 to 86 years) were randomly assigned to two groups (n=60) who were scanned with either the 80 kVp (“Group A”) or the 120 kVp (“Group B”) protocols using retrospective ECG gating. All patients had body mass index (BMI) under 25 kg/m2 and heart rates under 120 beats per minute. On a patient-by-patient and segment-by-segment basis, the signal-to-noise (S/N) and contrast-to-noise (C/N) ratios, effective radiation dose given in mSv, and diagnostic confidence (DC) were assessed for both groups by two independent readers with 8 and 7 years experience in coronary CT angiography.
Results: Patients in group A received a significantly reduced radiation dose of 2.57 mSv compared with 7.07 mSv in group B (p < 0.001). The total administered amount of Iodine per scan was also significantly lower in Group A (17.5g) than in Group B (24.5g). A significant reduction in image noise with higher S/N and C/N ratios in coronary vessels was seen in group B (p < 0.001). S/N ratios in group A were 18.7, 18.6, 18.7, and 18.6 for left main, proximal left anterior descending, proximal left circumflex arteries, and proximal right coronary, respectively, and 16.7, 17.4, and 18.3 for distal left anterior descending, distal left circumflex, distal right coronary arteries, respectively, in group A. Conversely, in group B the S/R values were 22.5, 22.0, 22.0, 21.4,19.0, 18.8, and 21.7 in group B patients. C/N ratios were 22.2, 22.1, 21.9, 22.1, 20.5, 21.0, and 21.9 in group A compared with group B patients, who had ratios of 26.6, 26.1, 25.9, 25.5,23.2, 23.0 and 25.6 (in a vessel-by-vessel assessment, each vessel in group B had p < 0.001). No significant difference in DC per patient was seen between the groups (ICC 1.0 for Group A and 0.9 for Group B).
Conclusion: The retrospective ECG-gated low-kVp low-volume contrast coronary CT angiography protocol provides angiograms without penalty in diagnostic confidence in patients with BMI up to 25 kg/m2 and heart rates of less than 120 beats/min. It is beneficial for patients whose kidney functions are not good and for those who increased risk for extravasations to diminish the risk of compartment syndrome in severe cases.

Published: March 2024

Objective: This study aims to assess the efficacy of CT-guided splanchnic nerve neurolysis in alleviating pain associated with malignancies in the upper abdominal viscera.
Methods: A single-arm investigation involved 20 patients diagnosed with upper abdominal visceral malignancies and experiencing pain with a VAS ≥ 7. All participants underwent CT-guided splanchnic nerve neurolysis utilizing absolute alcohol ablation. Pain intensity was measured using the visual analog scale (VAS) one-day post-procedure, at one week, and at one-month follow-up. The primary endpoint was to evaluate the effectiveness of pain relief based on VAS scores. Incidences of intra- and post-procedural complications were meticulously documented.
Results: The mean age of participants was 60.7±11.1, with 12 men and 8 women included in the study. Assessment of pain relief, as per the Visual Analogue Scale (VAS) one day following the intervention, revealed a 70% efficacy in the group with substantial relief and 30% with moderate relief. The average VAS score exhibited a significant decrease immediately post-intervention (8.7±1.1 vs. 3.4±1.3, p<0.05). The average VAS scores remained relatively stable at 2.6±1.5 and 2.1±1.5 at the one-week and one-month follow-up, respectively. Common complications included orthostatic hypotension (40%), initial pain (30%), acute intoxication (25%), and diarrhea (15%). No instances of severe complications were recorded.
Conclusion: CT-guided splanchnic nerve neurolysis using absolute alcohol is deemed a secure and productive method for promptly mitigating pain and sustaining pain stability for up to one month.
La representación del movimiento como problematización para enseñar M.R.U. y M.R.U.V.

Transitar por la “Física” en el nivel medio suele ser difícil, no solo porque se requiere de saber física sino también de dominar la matemática. Aún como estudiante del profesorado en física y ante el desafío del desarrollo de mi práctica docente, se me plantea trabajar con el MRU. Frente a la propuesta considerada personalmente como poco atractiva, se busca una alternativa que podríamos considerar “no convencional” que reconsidera el uso y la presentación que le damos tradicionalmente a las representaciones en física. A través de esta propuesta diferente, los estudiantes pusieron en evidencia con gran desarrollo, el sentido físico que lograron encontrar en las representaciones matemáticas de gráficos cartesianos, en diversos movimientos reales y modelizados, cumpliendo ampliamente con los objetivos que me proponía.
Análisis sobre las palabras específicas de la cultura china en el Nuevo Diccionario Chino-Español
Authors: Chen Xiang 
Published: March 2024

Como parte indispensable del idioma chino, las palabras y expresiones específicas de la cultura son difíciles para los hispanohablantes que estudian chino como lengua extranjera y necesitan una atención especial. Por lo tanto, se debería atribuir importancia a dichas palabras y expresiones en los diccionarios chino-españoles. No obstante, se encuentra que los diccionarios a menudo carecen de información de fondo cultural, las frases no se proporcionan con contextos efectivos, los refranes se privan de las historias de fondo relevantes, y las entradas de poemas, refranes y otros dichos resultan inadecuadas en términos de etimologías, etc. Teniendo en cuenta esto, tomamos el Nuevo Diccionarios Chino-Español (1999) como tema de investigación, y se sugiere que la compilación de los diccionarios chino-españoles podría guiarse por la teoría de la semiótica cultural: con motivo de construir “textos culturales”, que incluyan la estructura cognitiva de los estudiantes (interno) y reflejen las costumbres y el conocimiento de fondo chinos (externo), se pueden realizar mejoras en los diccionarios para estudiantes en los niveles macroestructural, microestructural y medioestructural. Sobre todo, la información puede reorganizarse y adjuntarse a las definiciones, sentidos correspondientes, etiquetas, glosas, ejemplos e ilustraciones. Con estas modificaciones implementadas, se espera que los diccionarios se conviertan en herramientas más útiles para consulta, lo que puede beneficiar a los estudiantes de chino como lengua extranjera y cerrar brechas en la comunicación intercultural.

Published: March 2024

Humans in the view of Islam have good innate potential. In the view of Islam, this potential is called fithrah. Humans since being born already have the potential for good and kindness. But in living his life, when humans relate to something outside themselves, due to environmental influences, humans who previously had good potential, became bad behavior and had bad morals.. The research used a qualitative approach with a literature study method. The research findings is moral education simply has the aim of improving student behavior and instilling it deeply so that the urge to have good behavior remains embedded in him. Humans have good innate potential (fithrah). Education as an effort to humanize humans is carried out to deliver humans to be as before, in a good state. Humans who return to the state of fithrah are humans with good morals. The process of moral education has the aim that humans become good human beings. In praxis, educational institutions not only prepare students to have certain intelligence and skills. Creating a good relationship between individuals and their God, both sirri (secretly) and a'lany (openly), makes individuals istikamah close to Allah Swt as if they see Him, feel His presence, and are sincere in worship.

Work Life Balance Problems of Industrial Workers in Kerala: A Study in the Perspective of Toiling Class Theory
Authors: Dhanabhakyam M. , Fahad K.P  
Published: March 2024

Since human resources are assets to the organizations, it is important to draw attention to their work life balance aspect. It is highly important in the industrial sector where the employees have to devote a lion’s share of their time for work and are hardly striving to balance their work lives and personal lives. The Toiling Class theory propounded by late former minister Sri KM Mani, clearly points out the relevance of work life balance. According to this theory, there are two classes of working people which include ruling class and toiling class where the latter (toiling class) is prone to the exploitation of the former (ruling class). Such exploitation probably results in detrimental effect on the work life balance of the toiling class. The researcher aims to analyze the work life balance of industrial workers in Kerala. A convenient sample of 116 industrial workers working in different industries in Kozhikode, Malappuram and Ernakulam Districts of Kerala were selected as a part of the study. Average Score Analysis, Independent sample t test and One Way ANOVA are the statistical tools used by the researcher for analyzing the Work Life Balance problems of the respondents. The results of analysis showed that there is moderate to high existence of work life balance problems or work life imbalances among the respondents. Various concerns of work life imbalance incorporated from the previous studies have proved to be the effect on the employees in the present study also. The findings of the present study provide worthy suggestions to the researchers, academicians and policy makers to understand and consider the work life balance problems of the industrial workers in Kerala

Authors: Zhang Yuting , Yu Han Hsing 
Published: March 2024

Purpose: This paper aims to investigate the effect of social capital on the contributions of knowledge and the behavior of citizens towards customer participation and value co-creation in virtual brand communities.
Design/Methodology/Approach: This study uses structural equation modelling (SEM) to analyse 213 questionnaires in order to validate a model that is based on social capital theory. This method examines the assumed theoretical connections assessing both the direct and indirect impacts of social capital on customer engagement in value co-creation.
Findings: The findings indicate that social interaction ties, principles of reciprocity and trust and a shared vision of social capital positively influence customers' knowledge contribution behaviors and citizenship behaviors for engaging in value co-creating in virtual brand communities.
Conclusion: The study concludes that societal capital plays a significant role in customer participation in value-creating behaviors within the communities of virtual brands.
Research Limitations/Implications: The main limitation of the study is the potential bias of self-reported data and it proposes to conduct a longitudinal study to dynamically understand customer engagement value co-creation and explore the interactions between dimensions of social capital.
Practical Implications: The study points out that strengthening social capital in virtual brand communities can motivate customers to participate more in knowledge contribution and civic behavior, thereby enhancing value co-creation. Therefore, companies should aim to strengthen interaction, trust and shared vision within the community to drive this process.
Contribution to the Literature: This study expands the existing research on value co-creation by revealing the mechanism of social capital influencing the participation of customers in value co-creation in virtual brand communities.

Published: March 2024

This paper deals with the design of a hybrid system for the generation of electricity and heat that will supply a remote fishpond in eastern Serbia. The proposed hybrid system consists of a micro-hydro power plant (MHPP), a photovoltaic (PV) generator, a combined heat and power (CHP) unit with one diesel generator, batteries, a converter, a thermal load controller (TLC), and a boiler. A comprehensive techno-economic analysis is performed in the HOMER Pro software, which evaluated and compared 12 possible configurations with different combinations of system components. The results show that the optimal system has the lowest total net present cost (NPC) and the lowest levelized cost of energy (COE) amounting to 284421.0 $ and 0.178 $/kWh, respectively. Compared to a diesel/batteries/converter/boiler hybrid system, the proposed system produces 65.4 % less greenhouse gas (GHG) emissions, while the shares of electricity, heat, and renewable energy generation are increased by 31.1 %, 5.0 %, and 51.2 %, respectively. It is shown that covering the demand for heat by regenerating the waste heat from the diesel generator and excess electricity from renewables contributes to reducing the total cost of the system and the GHG emissions. This finding finally emphasised the necessity of applying TLCs in off-grid hybrid systems.
