Authors: Freitas Felipe Augusto Marques de , Figueredo Kytéria Sabina Lopes de
Published: March 2024

A implementação do novo Ensino Médio (EM) tem sido um marco significativo no panorama educacional, trazendo consigo mudanças substanciais nas diretrizes e parâmetros curriculares. Essas mudanças não só remodelaram a estrutura educacional, mas também influenciaram diretamente no Programa Nacional do Livro Didático (PNLD). Visando refletir na percepção docente o atual contexto da educação e seus reflexos na construção do saber para o futuro. Esse estudo foi conduzido com uma metodologia qualitativa e de caráter exploratório, utilizando recursos documentais e um questionário semiestruturado, aplicado a três professores de escola pública no município de Portalegre -RN. Os resultados obtidos destacam a importância da formação docente como elemento fundamental para impulsionar o processo de ensino. É evidente, também, nas observações dos colaboradores, que a atual configuração do EM enfrenta desafios e problemas, a saber no campo das Ciências da Natureza e suas tecnologias (CNT), com redução na carga horária e conteúdos descontextualizados com a realidade social dos estudantes, em que são refletidos nos Livros Didáticos (LD), esses, que revisitam a necessidade de educadores preparados para lidar com a interdisciplinaridade, a flexibilidade curricular e a inovação pedagógica. Portanto, é importante que as políticas educacionais se concentrem em investimentos na formação contínua dos professores e na criação de ambientes de aprendizagem que promovam uma educação mais relevante e significativa para que professores e alunos enfrentem os desafios e tirem o máximo proveito das oportunidades oferecidas pela nova era educacional.

The use of near-Earth space for scientific and commercial purposes has skyrocketed in recent years. However, progress continues to be hampered by the cost and availability of vehicles relied upon for delivering payloads to the Earth’s orbit. The Riga Technical University (Latvia), with the assistance of the Technological University in Kielce (Poland), is developing a concept of a novel payload launch system. The implications of such a system for launching payloads into low Earth orbit (LEO) are presented in the article. The system, intended for launching small spacecraft, comprises the A319 MPA transport airplane used as a platform aircraft and a three-stage payload carrier, codenamed LatLaunch. The first and second stages of the three-stage launch vehicle are unmanned winged aircraft. The third stage is a classic rocket which, once dropped from the launch platform, takes the payload to a specific height, at a given rate of speed and at a predetermined trajectory angle. The article presents the results of a study focusing on designing this system.

This paper presents the concept of a remotely controlled mobile robot that generates a two-dimensional map of its surroundings. The hardware platform developed relies on the LINUX operating system with the Robot Operating System (ROS) to function properly. The authors focused on discussing the robot's hardware and presenting the software used. In line with the assumptions made, the robot is capable of generating a two-dimensional digital map of its surroundings, as well as of recording images of those surroundings. The robot relies on lidar odometry for identifying its position, meaning that the developed algorithm calculates the vehicle's location based on data from a laser scanner. The main sources of environment-related information acquired by the robot include the following: RPLidar A3M1 laser scanner by Slamtec (generating a digital map) and a 5mpx HD OV5647 camera (capturing images of the surroundings). These devices are coupled with the Raspberry Pi 3B on-board computer via a CSI interface.

Published: March 2024

O objetivo deste estudo é a análise das variantes para a consoante lateral dental em coda silábica na escrita de crianças em processo de alfabetização, e apontar quais procedimentos pedagógicos podem ser adotados para auxiliar no avanço consciente do processo de escrita. Para tanto, foram analisados os registros das variantes da lateral dental presentes na escrita de alunos do 2º ano do Ensino Fundamental.Utilizamos como base teórica o conceito de vocalização, processo fonológico no qual uma consoante é transformada em vogal ou semivogal em determinadas posições da sílaba ou da palavra. De acordo com a literatura, a vocalização da lateral dental [l] ocorre frequentemente em crianças em processo de alfabetização, e pode ser observada na escrita em momentos como a substituição de "l" por "u" ou a supressão da consoante final em palavras como "saudade" (sa[l]dade) ou "sal" (sa[u]).Nossos principais resultados mostram que a vocalização da lateral dental em coda silábica está presente nos escritos dos alunos analisados, de forma variada e frequente. Além disso, foi observado que a ocorrência de vocalização estava relacionada a fatores linguísticos, como a posição da consoante na palavra, e também a fatores regionais, já que o fenômeno da vocalização é mais comum em certas regiões do país.Com base nesses resultados, nossas contribuições são voltadas para a prática docente sistematizada. Propomos estratégias de ensino baseadas na consciência fonológica, atividades lúdicas e na vocalização da lateral dental, visando auxiliar no enfrentamento desse desafio da escrita. Acreditamos que essa abordagem consciente pode contribuir para a melhoria da aprendizagem da escrita e para a compreensão do processo fonológico da vocalização. Assim, nosso estudo busca contribuir para a compreensão desse fenômeno linguístico tão comum na fala das crianças em processo de alfabetização, oferecendo subsídios teóricos e práticos para os professores que lidam com esse público.

Principal component analysis on the effect of early morning awakening in major depressive disorder
Authors:   Valdosta State University, Department of Biology, 1500 N Patterson St., Valdosta, Georgia 31698, USA, Higdon Julia R.
Published: March 2024

Sleep disturbance is one of the most prevalent symptoms associated with Major Depressive Disorder (MDD). A recent article (Wu et al., 2022, Journal of Multiscale Neuroscience 1, 133-139) explored the significant relationship between early morning awakening (EMA), a type of sleep disturbance, and recovery in MDD patients. In the paper, the authors examined the relationship between EMA and the treatment of MDD with twelve neuropsychological parameters. The authors employed two univariate statistical techniques, students’ t-test and ANOVA, to analyze their data. While their analysis derived a meaningful conclusion that EMA may result in a statistically and clinically significant delay in recovery, we found that a multivariate statistical technique, principal component analysis (PCA), extracted additional quantitative information from their study. In this paper, we present quantitative features in the interaction between EMA and the treatment of MDD obtained from PCA.

Published: March 2024

Mulut merupakan habitat bagi sekitar 700 spesies bakteri yang dapat memicu gangguan jika kebersihan mulut tidak terjaga. Salah satu upaya menjaga kebersihan mulut adalah dengan menggunakan mouthwash atau obat kumur. Saat ini masih banyak beredar obat kumur di pasaran yang mengandung alkohol, padahal penggunaan alkohol dalam obat kumur dapat menimbulkan beberapa efek samping setelah pemakaian. Di sisi lain, terdapat bahan alam yang memiliki aktivitas antibakteri terhadap bakteri mulut seperti Salvadora persica dan Syzygium aromaticum. Minyak cengkeh merupakan minyak atsiri yang kurang stabil, sehingga pada penelitian ini dikembangkan formula nanoemulsi minyak cengkeh dengan penambahan ekstrak siwak. Formula akhir nanoemulsi diuji aktivitas antibakterinya terhadap bakteri dari saliva mencit galur BALB/c melalui penentuan konsentrasi hambat minimum (KHM). Pada formula akhir, diperoleh nanoemulsi dengan ukuran 22,4 nm dengan indeks polidispersitas 0,385, zeta potensial -2,1 mV,dan pH 7,15. Hasil uji aktivitas antibakteri menunjukkan bahwa nanoemulsi yang ditambahkan dan tidak ditambahkan ekstrak siwak memiliki KHM terhadap bakteri saliva mencit sebesar 6,25 mg/ml. Hal ini disebabkan karena KHM dari minyak cengkeh adalah 6,25 mg/mL, sedangkan dari ekstrak siwak adalah 12,5 mg/ml sehingga jumlah ekstrak dalam formula tidak dapat menurunkan KHM nanoemulsi. Hasil uji stabilitas menunjukkan bahwa nanoemulsi stabil terhadap 2 siklus beku-cair dan masih dapat diterima pada penyimpanan selama 4 minggu dalam suhu 4°C. Oleh karena itu, dapat dikatakan bahwa formula yang dikembangkan memiliki aktivitas antibakteri terhadap bakteri saliva mencit BALB/c dan memiliki stabilitas yang cukup baik selama 4 minggu dengan suhu penyimpanan 4°C.

Using UK Data to Study the Effects of Dividends Announcements on Stock Market Returns
Authors: Hasan Fakhrul
Published: March 2024

Using a sample of firms listed on the FTSE-350, this study examines the effects of dividends announcements on the London Stock Exchange (LSE) during the period from 1990 to 2019. We use the dividend-signalling hypothesis to test whether dividends announcements have any effects on stock returns. Our results suggest that dividend increase announcements have a positive effect on stock returns, and dividend decrease announcement reduce stock returns. On average, a dividend increase is estimated to increase stock returns by 6 basis points and a dividend decrease is estimated to reduce stock returns by the same amount. These findings are consistent with the dividend-signalling hypothesis.

Published: March 2024

Pre-trained language models (PLM) based on transformer neural networks developed in the field of natural language processing (NLP) offer great opportunities to improve automatic content analysis in communication science, especially for the coding of complex semantic categories in large datasets via supervised machine learning. However, three characteristics so far impeded the widespread adoption of the methods in the applying disciplines: the dominance of English language models in NLP research, the necessary computing resources, and the effort required to produce training data to fine-tune PLMs. In this study, we address these challenges by using a multilingual transformer model in combination with the adapter extension to transformers, and few-shot learning methods. We test our approach on a realistic use case from communication science to automatically detect claims and arguments together with their stance in the German news debate on arms deliveries to Ukraine. In three experiments, we evaluate (1) data preprocessing strategies and model variants for this task, (2) the performance of different few-shot learning methods, and (3) how well the best setup performs on varying training set sizes in terms of validity, reliability, replicability and reproducibility of the results. We find that our proposed combination of transformer adapters with pattern exploiting training provides a parameter-efficient and easily shareable alternative to fully fine-tuning PLMs. It performs on par in terms of validity, while overall, provides better properties for application in communication studies. The results also show that pre-fine-tuning for a task on a near-domain dataset leads to substantial improvement, in particular in the few-shot setting. Further, the results indicate that it is useful to bias the dataset away from the viewpoints of specific prominent individuals.

Perspective Chapter: Management of Weeds in Organic Farming System – Special Focus on Organic Vegetable Farms of the USA
Authors: Shrestha Swati , Beneton Karina , Gweneth Abit Ma. , Shrestha Sanju , Dar Amna
Published: March 2024

Weed management is an important challenge in all farming systems, but it is more complicated in organic farming due to lack of chemical options. Concern about potential increases in weed populations without the use of herbicides has limited the uptake of organic farming even though organic products are gaining popularity among consumers. Different weed management strategies differ in their ability to control weeds, and often have unique agroecological implications. Broadleaf weeds, grasses and sedges are the three major classes of weeds impacting quality and yield in both horticultural and row crop systems. In an organic production system, the major concern is how and when to adopt the management practices to make the system productive and profitable. Generally, an integrated management approach using organic herbicides, mechanical, cultural, and biological practices is considered best for weed control in organic system. However, a systematic literature on different methods for weed management in organic farming system is not well developed. This book chapter outlines major weed problems in organic farming and various methods of weed control. The chapter is expected to disseminate information on strategies for sustainable weed management in organic farming systems.
Renoprotective interventions efficacy in the late stages of CKD
Authors: Sergeevna Sadovskaya Daria
Published: March 2024

The efficacy of renoprotective interventions in the late stages of chronic kidney disease (CKD) varies significantly from that in the early stages, with approaches in advanced CKD being insufficiently developed and sometimes conflicting. In a small prospective study, we evaluated the effectiveness of intensive follow-up protocol aimed at reducing CKD progression rates, cardiovascular complications, and improving outcomes among 100 patients with CKD3B-5 stages at a single center. This evaluation was compared with the outcomes of standard nephrology care. Positive changes in modifiable parameters resulting from interventions (such as serum albumin, hemoglobin, and standard bicarbonate) or reductions in negative parameters (like serum phosphate, plasma calcium deviation from target range, uric acid, and systolic blood pressure) were independently associated with a comparable reduction in the decrease of glomerular filtration rate (GFR). For the treatment group, the predicted time to reach the need for renal replacement therapy (RRT) from a conditional GFR of 20 ml/min/1.73 m2 was 5 months longer than in the regular follow-up group. The distribution of average GFR at the start of dialysis suggested a late and possibly premature start in the control group, with less than 60% of cases being planned. In contrast, the treatment group always had a planned start.
Perspective Chapter: Structures of Thinking in Community-Based Working Culture – Renewing Social Work Practices
Authors: Pekkarinen Anna , Kiviranta Joonas , Talvikki Tumi Tuuli , Metteri Anna
Published: March 2024

In this article, a community-based working culture is introduced, and the development of social work orientations within a socially and culturally diverse community in Finland is examined through a case study. The objective is to expand understanding of the evolution of social work, grounding it in its ethical foundations. Two authors have previously synthesized competences of community social work; here, these competences are revisited in the context of recent practice development, with a focus on deconstructing power and knowledge. The assertion is that structures of thinking are a requisite to translate competencies into action, while moral courage and a tangible scope for action are essential to transforming practices. Tailoring social work to the lived experiences and contexts of those in need is imperative to effectively respond to evolving social challenges, some of which emanate from structural injustices.

Published: March 2024

The present study was focused on the assessment of heavy metals in Lower Lake of Bhopal. With reference to toxic metal contamination, water samples were collected quaterly from four stations mentioned for a period of two years (January 2020 to December 2021). Heavy metals, i.e., iron, zinc, chromium, copper, and nickel were determined in surface and bottom waters taken from the Lower Lake, Bhopal, using atomic absorption spectroscopy (AAS) according to the Standard Methods of American Public Health Association (APHA). The range values of these metals were compared with the tolerance limits as laid down by the Central Pollution Control Board (CPCB), India. Results of this analysis revealed that the concentration of these metals was below the permissible limits both in surface and bottom waters except Fe, which was alarming. It was concluded that the metals (Fe, Zn, Cr, Cu, and Ni) were present in water, and the contamination was supposed to be due to a high degree of anthropogenic stress including idol immersion activity. The water quality of the Lake reveals that although the situation is not too bad, it is alarming. Proper conservation and management plans and strategies have to be formulated and implemented for the restoration, conservation, and management of these water bodies at the government and public level.
Perspective Chapter: Through Empathizing to Co-Constructing Uniquenesses
Authors: Stewart John
Published: March 2024

The traditional understanding of empathy as the capacity to sense and respond appropriately to another’s thinking and feeling effaces two related features of the important human events that his term attempts to name: their interpersonal nature and their culturally situated quality. Recent conceptual revisions helpfully respond to these effacements and position researchers to address a third feature of both traditional and revised versions of the construct; namely, empathy’s dependence on similarity. I address this feature here. I argue that empathy’s dependence on similarity makes it the penultimate rather than the decisive interpersonal event enabling humans to establish and maintain social and personal relations. Close relationships foreground not just similarities identified with the help of empathy but also differences; i.e., uniquenesses that are situation-specific and co-constructed in verbal/nonverbal talk. After describing what is meant by “co-,” “constructed,” and “uniquenesses,” I use close readings of three actual conversations to display how this process unfolds and to argue for the efficacy and utility of supplementing one’s focus on empathizing with close attention to how conversation partners co-construct uniquenesses.

Published: March 2024

This chapter highlights the diversity of Ethiopian fish species across 12 drainage basins. These include the Wabishebele-Genale, Abay, Omo-Gibe, Awash, Rift Lakes, and Baro Akobo basins. Ethiopia’s lakes, rivers, and reservoirs harbor over 200 fish species, categorized into East African, Nilo Sudanic, and endemic forms. The Nilo-Sudanic species are most diverse, particularly in the Abay, Baro-Akobo, Omo-Gibe, and Tekeze basins. Highland lakes and northern Rift Valley lakes host East African forms. Each of the seven drainage basins holds varying numbers of fish species, with high levels of endemism in the Abay, Rift Valley, and Awash basins. Endemic species counts are as follows: Abay (23), Rift Valley (7), Awash (6), Omo (2), and Baro (1). Rapid population growth, unemployment, and ineffective fisheries management threaten fish diversity. To prevent further degradation, urgent watershed management actions such as forestation, soil conservation, controlled grazing, and banning hillside crop farming are imperative in Ethiopia.
Progress on Application of Ceramic-Matrix Composites in Hot-section Components in Aero Engines
Authors: Li Longbiao
Published: March 2024

Ceramic-matrix composites (CMCs) are a class of materials that combine the high-temperature stability and strength of ceramics with the toughness and damage tolerance of fibers. One of the key advantages of CMCs is their ability to withstand high temperatures, making them ideal for applications in gas turbines, rocket nozzles, and heat exchangers. The high-temperature stability of CMCs is due to the ceramic-matrix material, which has a high melting point and excellent thermal conductivity. This allows CMCs to operate at temperatures above 1000°C, where traditional metal alloys would fail. These composites have gained significant attention in recent years due to their potential for use in a wide range of applications, including aerospace, automotive, energy, and defense. This chapter reviews the recent progress in the design, application, and challenges in CMCs, especially the hot-section components design and testing at elevated temperatures.
Perspective Chapter: Determinative Factors for Bridging Social Inequality Gaps – A South African Perspective
Authors: Kakwata Frederick
Published: March 2024

South Africa’s society has been significantly impacted by its colonial past and apartheid policies, resulting in long-lasting disparities based on race, class, and gender. Historical events have shaped the social structures and organisations that maintain inequality. The country exhibits pronounced income inequality, exacerbating social inequalities by impeding individuals with limited resources from accessing necessities and opportunities for upward social mobility. This study is a literature review that uses qualitative content analysis and an inductive approach as the methodological framework. It aims to investigate the factors contributing to bridging gaps in social inequality in South Africa. The findings indicate that several key factors, such as limited access to quality education, basic services, and employment opportunities, have contributed to social inequality in South Africa. The government has implemented redistribution of wealth, affirmative action, black empowerment, subsidised education and skills training to improve employment prospects, low-cost health services, and affordable housing to reduce socio-economic inequalities. However, corruption and a lack of political will pose significant obstacles and constraints. The government needs to address these barriers and develop comprehensive policies to reduce social inequality in the country.

Published: March 2024

For people with schizophrenia, home environments that are readily understandable, easily managed, provide opportunities for self-expression and support psycho-social needs can enhance their wellbeing. Importantly, symptoms of schizophrenia (including agitation, anxiety, helplessness, perceptual distortion) can potentially be reduced through responsive accommodation design. The embedded potential of design of homes to offer support or create hindrances for people with schizophrenia has been poorly explored. Cues as to what things are and how to function in a space can be designed to provide support. This chapter records a multi-prong action research approach to develop a resource to assist designers and service providers create responsive residential environments for people with impeded cognitive functioning. Research from such fields as environmental psychology, sociology and design, together with discussions with people with schizophrenia, indicates that quality of life for people with schizophrenia can be enhanced through design. A key outcome is a Framework that enables the user to both understand the reason why a person with schizophrenia may respond to the environment in a particular way and how to design to acknowledge that potential response.

Authors: Sato Hector , Gómez Villafañe Virgina , Bonillo Germán , Maria Gonzalez Ana
Published: March 2024

The main objective of this work is to conduct a review of the uses of parasitic plants of the family Balanophoraceae present in Argentina. This study attempts to change the perspective on parasitic plants, shedding light on their inherent value and economic importance in certain communities in Argentina. Rather than adhering to the prevailing bias that all parasitic plants are harmful or simple weeds, this study aims to redefine such perceptions. It highlights the fact that some parasitic plants play fundamental roles as sources of livelihood, traditional medicine, or ornamental elements among local populations. In addition, this study highlights the importance of certain parasitic plant species that face conservation threats. Their prioritization stems from the global commitment to biodiversity conservation. The exploration of these unique plants and their functions within ecosystems highlights the intricate interaction between species and their environment. Taken together, this research contributes to a more nuanced understanding of parasitic plants, recognizing their multifaceted contributions, economic potential, and crucial role in the broader context of biodiversity conservation.
Silicone Embolism Syndrome Causing Altered Mental Status and Respiratory Failure After an Unlicensed Gluteal Silicone Injection: A Case Report
Authors: Lin Christopher , Robison Jeremiah
Published: March 2024

Introduction: Unlicensed cosmetic procedures, which come at increased risk of infection and potential surgical complications, have introduced new challenges in healthcare. Physicians should be aware of presentations that may arise secondary to these procedures.Case Report: We describe a case in which a previously healthy, 28-year-old female presented with new-onset seizures and acute respiratory distress syndrome (ARDS) in the setting of a recent cosmetic procedure with silicone injections to the gluteal region. The patient’s hospital course was complicated by altered mental status, respiratory failure, rapid hemodynamic compromise, and eventual death.Conclusion: In rare cases, one possible complication of cosmetic procedures is silicone embolism syndrome, which is characterized by pneumonitis, alveolar hemorrhage, and ARDS. The patient described in this report also experienced neurologic symptoms including seizure and altered mental status. This is a clinical diagnosis that relies upon thorough history-taking and detailed physical exam. Documentation on this phenomenon is limited, and medical management has not yet been standardized for this condition. Morbidity and mortality remain high.

Authors: McGuire Duncan , Calleja Robert , Pai Eric , Bahl Amit
Published: March 2024

Introduction: Vision loss is a symptom found frequently in patients presenting to the emergency department (ED). Central retinal artery occlusion (CRAO) is an uncommon yet time-sensitive and critical cause of painless vision loss in which delayed diagnosis can lead to signiﬁcant morbidity. Emergency medicine literature documents the ability to diagnose a CRAO using ultrasound by identifying the hyperechoic thrombus coined the retrobulbar spot sign.Case Report: We present the case of a patient presenting with painless monocular vision loss for which CRAO was diagnosed in the ED using point-of-care ultrasound enhanced by the utilization of serial Doppler examinations as well as calculation of the central retinal artery resistive index.Conclusion: Despite the pre-existing literature on point-of-care ultrasound investigation of central retinal artery occlusion, there are no emergency medicine case reports describing serial examination of the central retinal artery by spectral Doppler or calculation of arterial resistive index to improve this evaluation and monitor progression of the pathology.

Authors: Meloy Patrick , Lindquester Will S. , Stebbins Jeffrey , Bromberek Elaine
Published: March 2024

Introduction: Visceral arterial aneurysms and pseudoaneurysms are rare but dangerous pathologies, with reported incidence of 0.01–0.2% of the worldwide population, as found on autopsy. Pancreaticoduodenal artery pathology accounts for approximately 2% of all visceral aneurysms; it is commonly caused by chronic inﬂammatory processes, such as pancreatitis or adjacent pseudocysts. Morbidity and mortality commonly result from rupture of the aneurysm itself, leading to life-threatening hemorrhage into the peritoneum or gastrointestinal tract.Case Report: Here we present the case of a 64-year-old male patient with previous history of alcohol use disorder leading to chronic pancreatitis and prior embolization of an inferior pancreaticoduodenal pseudoaneurysm, who presented to the emergency department (ED) with abdominal pain, nausea, and vomiting, and was found to have a large recurrent inferior pancreaticoduodenal pseudoaneurysm with associated obstructive cholangitis and pancreatitis via contrast-enhanced computed tomography (CT) of the abdomen and pelvis. The patient was managed emergently by interventional radiology angiography with embolic coiling and percutaneous biliary catheter placement, and he subsequently underwent biliary duct stenting with gastroenterology. The patient was successfully discharged after a brief hospitalization after resolution of his pancreatitis and associated hyperbilirubinemia.Conclusion: Pancreaticoduodenal artery aneurysms and pseudoaneurysms are rare and dangerous visceral pathologies. Patients can be diagnosed rapidly in the ED with CT imaging and needurgent endovascular management to prevent morbidity and mortality.

Authors: Abd Elmohsen Bedewy Ahmed , Mohamed Maged Salah , Sultan Hesham Mohamed , Khalil Moataz Salah
Published: March 2024

Background: Modified radical mastectomy (MRM) is the primary surgical treatment for breast cancer, yet it leads to significant postoperative pain. Objectives: This randomized controlled trial evaluates the effects of an erector spinae plane block (ESPB) versus a serratus anterior plane block (SAPB) on post-MRM pain management and stress response reduction. Methods: Sixty individuals scheduled for unilateral MRM under general anesthesia from October 2021 to October 2022 were divided into three groups. Group A comprised 20 patients who received ultrasound-guided ESPB (20 mL of 0.25% bupivacaine). Group B included 20 patients who received ultrasound-guided SAPB (20 mL of 0.25% bupivacaine). Group C was treated with intravenous morphine based on pain scores. Anesthesia was induced using 2 μg/kg of fentanyl and 2 - 3 mg/kg of propofol. The study compared the three groups regarding pain scores using a numerical rating scale, serum cortisol levels, total fentanyl, and morphine consumption, changes in mean arterial blood pressure (MAP) and heart rate (HR) during surgery, and the occurrence of postoperative complications. Results: Statistically significant reductions in pain scores were observed in group A compared to groups B and C. Moreover, group A exhibited a significant decrease in postoperative morphine consumption, serum cortisol levels 1 hour post-surgery (P = 0.021), MAP, and postoperative vomiting and nausea compared to group B. Furthermore, groups A and B showed statistically significant improvements in all parameters compared to group C. Conclusions: The study demonstrates that ESPB provides superior analgesic effects compared to SAPB in patients undergoing MRM, with reduced morphine use and lower postoperative cortisol levels. Both blocks offer more effective pain control than intravenous morphine alone.

Background: Spinal fusion surgeries are often associated with major blood loss. The aim of this study was to investigate the effect of oral clonidine as premedication on the amount of blood loss and the need for blood transfusion during lumbar laminectomy spine surgery with pedicle screw insertion, achieved by controlled hypotension. Methods: In this double-blind randomized clinical trial, 100 patients scheduled for lumbar spine laminectomy with pedicle screw insertion (as a fusion procedure) were included. Patients were classified into two groups: The intervention group received a 0.2 mg clonidine tablet one hour before entering the operating room, and the control group received a placebo. The patients were compared with respect to hemodynamic variables, quality of the surgical field, duration of the surgery, estimated amount of blood loss, and any blood transfusion. Results: Oral clonidine was found to be significantly better in terms of maintaining stable dynamics and having a lower amount of blood loss, thereby requiring fewer blood transfusions compared to the control group. Conclusions: Premedication with 0.2 mg oral clonidine in patients undergoing lumbar spine laminectomy with pedicle screw insertion results in improved perioperative hemodynamic stability and a reduction in the amount of intraoperative blood loss, thereby reducing the need for blood transfusion.
Completeness also Solves Carnap’s Problem

In what sense, and to what extent, do rules of inference determine the meaning of logical constants? Motivated by the principle of charity, a natural constraint on the interpretation of logical constants is to make the rules of inference come out sound. But, as Carnap observed, although this constraint does rule out some non-standard interpretations, it does not rule them all out. This is known as Carnap’s problem. I suggest that a charitable interpretation of the logical constants should, as far as possible, make the rules of inference both sound and complete, and I show how this idea can be brought to bear on a successful solution to Carnap’s problem in the case of classical propositional logic, as well as classical first-order logic. In fact, the solution generalizes to any logic whose rules of inference are sound and complete with respect to a bivalent semantics that is classical with respect to negation.

Siyalore, tükürüğün aşırı salgılanması ve ağız köşesinden akması olarak tanımlanır. Fiziksel ve psikososyal pek çok komplikasyona yol açabilen ve kişinin yaşam kalitesini önemli ölçüde düşüren bu durumun tedavisi için altta yatan nedenin doğru belirlenmesi önemlidir. Etiyolojisinde pek çok faktör rol oynadığı gibi klinikte ilaç kullanımına bağlı yan etki olarak da ortaya çıkabilmektedir. Psikiyatride kullanılan ilaçlar arasında siyalore ile en çok ilişkilendirilen ilaç klozapin olmasına rağmen, diğer birçok psikotrop ilaç nedeniyle de siyalorenin ortaya çıkabileceğini belirten yayınlar bulunmaktadır. Bu nedenle psikotrop ilaç kullanan kişilerde, siyalore etiyolojisinde ilaç yan etkisi de göz önünde bulundurulmalıdır. Bu yazıda, organik olmayan psikoz tanısıyla takip edilen 59 yaşında kadın hastada risperidon kullanımına bağlı siyalorenin literatür bulguları ışığında tartışılarak mevcut literatüre katkı sağlanması amaçlanmaktadır.

Background. Smash is synonymous with powerful punches and swift dives. Accuracy stands as the primary factor that holds significant importance. Purpose. The purpose of this study is to investigate the relationship between the independent variables, namely explosive power, elbow angle, and jump height, and the dependent variable, which is smash accuracy. Methods. Descriptive research design with correlational methods. This research involved a group of 15 male student athletes, whose age (M ± SD = 21.27 ± 1.163 years) and height (M ± SD = 167.67 ± 1.877 cm) were recorded. The sampling technique used purposive sampling, with certain criteria. Prerequisite tests such as normality test and linearity test were conducted, followed by hypothesis testing. The data was analyzed using SPSS 26.0. The results. The results demonstrate a significant and simultaneous asscosiation between the independent variable and the dependent variable, as indicated by the observed significance value of 0.015 <0.05. The data output reveals a simultaneous correlation coefficient of R = 0.776, with a determination coefficient of Rsquare = 0.601, indicating that 60.1% of the variation in the dependent variable can be explained by the independent variables. The remaining 39.9% is attributed to and explained by factors other than the independent variables. Conclusions. The findings and discussion of the research demonstrate a noteworthy association between explosive power, elbow angle, and jump height, and the accuracy of smashes in volleyball. As a result, this study presents substantial evidence supporting the significant contributions of explosive power, elbow angle, and jump height to smash accuracy.
Consumerisation of IT: Intersection of development streams of business and personal IT
Authors: Petrović Marijana , Sakal Marton
Published: March 2024

Background: In the age of IT consumerisation, private owned IT artifacts are increasingly used for business purposes. Management's approval is not required, but various approaches are used to create effective management strategies. Purpose: The historical development trends of business and personal ICT are examined in the paper to understand their intersection-IT consumerisation. Study design/methodology/approach: The paper provides a preliminary research assessment. The informative outcomes drawn from diverse perspectives and the comprehensive nature of 'gray literature' should serve as guidance for the direction, adjustments, and modifications of future research. Findings/conclusions: A number of technological and market factors have led to the consumerisation of IT. As a spinout from business IT, personal IT has had a feedback effect on it: the proliferation of computers and mobile devices on the consumer market, combined with affordable Internet-related resources, not only changed personal IT usage patterns, but also redefined the expectations that users have for enterprise software. In order to create an effective IT consumerisation management strategy, it is imperative to understand them. Limitations/future research: The paper is a starting point for future empirical research in the field of IT consumerisation, and as such, may be amended according to new knowledge that is obtained subsequently.

The aim of this research was to investigate how gender diversity and tax aggressiveness impact the profitability of mining sub-sector companies listed on the Indonesia Stock Exchange (IDX) from 2017 to 2022. The study encompassed a population of 75 such companies. Data collection was conducted through purposive sampling, and analysis employed multiple regression using the Eviews 8 software. The findings revealed that gender diversity did not have a significant effect on the profitability of mining sub-sector companies during the specified period. However, tax aggressiveness was found to have a positive impact on profitability within the same group of companies. Additionally, when considered together, gender diversity and tax aggressiveness were found to collectively influence profitability. It was also noted that 6.06% of the variability in profitability could be attributed to gender diversity and tax aggressiveness, while the remaining 93.94% was influenced by other unexamined variables.

Published: March 2024

This study examines the dissemination of the vision, mission, goals, and objectives (VMGO) of Urdaneta City University (UCU) and explores the ethical implications associated with their implementation. The VMGO serves as the guiding principles for UCU’s strategic planning and decision-making processes, shaping the institution’s identity and direction. However, the effectiveness of these VMGO relies on their dissemination among the primary stakeholders, the students. This research aimed to assess the current state of dissemination of UCU’s VMGO and identify potential ethical implications arising from any gaps or shortcomings in these processes. The study employed a mixed-methods approach, combining surveys, document analysis and philosophical interpretation. The survey gathered quantitative data regarding stakeholders’ experiences on the dissemination of the VMGO, while philosophical interpretation provided in-depth insights of ethical implications into their perceptions and experiences. Additionally, an analysis of relevant documents, such as official university publications and communication materials, provided contextual information. The study concluded that UCU can strengthen its commitment to integrity, teamwork, competence and transcendence that will foster a sense of purpose, honesty, accuracy, alignment, responsibility, respect, collaboration and societal impact within the university community. By upholding these values, UCU can strengthen its commitment to ethical practices, maintain the integrity of its messaging, encourage collaboration and inclusivity, enhance competence, and promote positive societal impact.
