Authors: Makasów Klaudia
Published: October 2024

Russian aggression against Ukraine has far-reaching consequences not only for the oppressed country, but for the whole world. However, it affects refugee children from Ukraine, who are experiencing ‘displaced childhood’. Additionally, burdened by trauma, culture shock and identity destabilization, they may experience many disorders (e. g. post-traumatic stress disorder) that resonating throughout their adult lifes. In order to minimize the negative effects of ‘displaced childhood’ these individuals are being included into by inclusive children the Polish education system and theseby lives are being structured. A stabilizing role is also played by bibliotherapy taking place in the Voivodeshi and Municipal Public Library in Gorzów Wielkopolski, which is a form of desensitization for refugee children. This article also draws attention to the challenges faced by Polish educational institutions and cultural institutions in the face of the mass influx of young immigrants to Poland.
Oddychanie – ważny element profilaktyki uniwersalnej
Authors: Gebreselassie Jolanta
Published: October 2024

The aim of the article is to reflect on the properties of respiratory, which should be the main element of the prevention of voice and speech disorders. Theoretical considerations include the issues of physiological respiratory. A contemporary, narrow concept of prevention is also signaled, which deserves attention due to its significant practical importance. With a view to being useful for teachers and speech therapists, the last part includes suggestions for respiratory exercises to be used when planning and conducting activities at the level of universal prevention. The study assumes a close connection between theoretical reflection and solutions to real preventive-diagnostic-therapeutic problems, because, as Franciszek Grucza wrote, “science and practice mutually determine each other, are mutually dependent on each other”.

Los resultados mostraron que el pastizal kikuyo se encuentra en zonas óptimas para su desarrollo, mientras que la melina y el tabaco, aunque en su mayoría en áreas adecuadas, no alcanzan su máximo potencial debido a ciertas limitaciones en el terreno. En conclusión, la zonificación agroecológica en La Maná es una herramienta valiosa para mejorar la eficiencia agrícola y fomentar un uso más sostenible de los recursos naturales, asegurando así la viabilidad a largo plazo de la actividad agrícola en la región.
Clinical pathological features and radiotherapy treatment for adenoid cystic carcinoma of the head and neck
Authors: Maluf Gabriel , Vianna Alberto , Kenupp Maria Graziela , Uyeda Mari
Published: October 2024

Adenoid Cystic Carcinoma (ACC) is a slow-growing, locally invasive malignant tumour, with a deceptively benign histological appearance, a high probability of local recurrence and distant metastasis. The tumour comprises basaloid cells with small, angular and hyperchromatic nuclei and scarce cytoplasm arranged into three significant prognostic patterns: cribriform, tubular, and solid. In some tumours, dedifferentiation to a high-grade form occurs. The authors have reviewed numerous studies which have attempted to demonstrate accurate histological prognostic features, but these have often produced conflicting results.
The literature review suggests that Analysis of microarray and gene expression profiles provided new potential diagnostic and prognostic markers. However, tumor grade, lymph node metastasis, invasion of major nerves, and resection margin status continue to be the most consistent predictors of prognosis. The optimal treatment of ACC has not yet been fully established, although most studies advocate using surgical excision and postoperative radiotherapy. Careful tumor staging and grading with documentation of perineural invasion and margin status remain important prognostic tools. ACC has been incurable, and most patients will eventually succumb to local recurrence, distant metastasis, or both. The clinical course of the disease can be surprisingly heterogeneous, with some patients surviving decades and others surviving only months. The combination of surgery and radiotherapy in the postoperative period has shown the best locoregional disease control.
Contribution to Evidence-Based healthcare: This review contributes to a better understanding of the treatment of patients diagnosed with cystic adenocarcinoma of the head and neck, with regard to treatment with curative radiotherapy, as part of the proposed treatment or even to reduce the effects of the disease.

Exploring the influence of e-governance on family business strategy execution
Authors: MANSOURI ALI , BELHAJ Ismail
Published: October 2024

In a context marked by increasing digital transformation, this study sets out to examine the influence of e-governance on strategy execution within family businesses in Morocco. Adopting a qualitative approach, this research looks specifically at the effects of three dimensions of e-governance - e-participation, e-transparency, and e-accountability - on the effectiveness of strategic execution. Based on data collected from 31 family businesses, the analysis reveals that e-participation and e-accountability contribute significantly to improving strategic alignment, thus fostering more efficient strategic execution. On the other hand, the impact of e-transparency, while relevant, remains less pronounced. This study enriches the literature by highlighting the transformative potential of e-governance in the strategic management of family businesses, while taking into account the particularities of family culture, resistance to change and technological capabilities specific to these organizations.

The study objective is to examine the impact of the metaverse and corporate social responsibility (CSR) on agriculture production and accounting firm performance output of Nigerian firms. The study ascertained that metaverse is described as a communal virtual shared environment that is produced when physically persistent virtual reality (VR) and virtually augmented physical reality collide while CSR assists firms in becoming socially responsible to the public, their stakeholders, and themselves. the study findings recognized that firms that effectively use technology to showcase their dedication to ethical CSR practices will likely draw investors who support the Sustainable Development Goals (SDGs). Thus, the production of agricultural products and the performance of accounting businesses within Nigerian firms are significantly impacted by both the metaverse and CSR. Their integration improves community ties, stimulates creativity, increases productivity, supports sustainability, and eventually results in a stronger economic framework within Nigeria's crucial agriculture industry. It was concluded in the study that the synergistic impact that improves the performance of accounting firms and agricultural production is produced when CSR initiatives are combined with metaverse technologies. Businesses can create creative solutions to address social concerns that farmers confront, including market access or teaching about sustainable practices, by utilizing the metaverse technology included in CSR frameworks

Ovoid pontics in the aesthetic management of the upper anterior sector. Case report
Authors: Espinal Mora Juan Carlos , Díaz Pérez Carlos Alberto
Published: October 2024

Tooth loss in the anterior sector causes not only functional alterations, but also aesthetic ones that alter people's quality of life, which is why its rehabilitation is one of the most common demands of patients in dentistry. One of the techniques used for the aesthetic management of partial edentulism is ovoid pontics. The clinical case of a 46-year-old female patient treated at the dental and aesthetic surgery postgraduate clinic of the San Gregorio de Portoviejo University, for the rehabilitation of the edentulous upper anterior sector, is reported. After the clinical radiographic study, the diagnosis and a comprehensive and interdisciplinary treatment plan were established, which included: oral prophylaxis, removal of dental calculus, endodontics, dental surgery, surgical procedure for modeling the gingival ridge, and creation of ovoid pontics with Zirconium. The ovoid pontic made with zirconium to rehabilitate the anterior areas of the oral cavity is an excellent option that meets the aesthetic and functional expectations of the patient

A Text-based Intelligently driven Emotion Recognition Framework
Authors: Wu Xiaoping , Lu Hanyu
Published: October 2024

Introduction: Emotion recognition from text has gained considerable interest due to its applications in human-computer interaction, emotion analysis, and psychiatric research. Traditional methods have struggled with emotional ambiguity, cultural nuances, and the dynamic nature of language, which affect the reliability of emotion recognition. This paper presents a novel emotion recognition framework named Artificial Gorilla Troops driven Modified Gaussian Support Vector Machine (AGT-MGSVM).Methods: We gathered a publicly available ISEAR dataset containing various textual emotional expressions and applied natural language processing (NLP) techniques for text pre-processing. The suggested AGT-MGSVM approach combines the resilience of the Gaussian assist vector gadget (GSVM) with the ability of AGT, a bio-stimulated optimization method. AGT improves the MGSVM with the aid of dynamically regulating its parameters based on the evolutionary conduct of gorilla troops, optimizing the version to enhance emotion popularity. Results: We examine the performance of the proposed technique against traditional emotion reputation methods using standard metrics inclusive of recall (89.2%), precision (89.5%), F1-score (89.4%), and accuracy (89.9%). Conclusion: The counseled AGT-MGSVM method is a promising improvement in intelligence-driven emotion reputation from the text.

Published: October 2024

State-owned energy, transportation, and telecommunications enterprises power many countries' economies and societies. Considering commercial and social objectives, SOE performance evaluation is complex. Rather than innovation, sustainability, and stakeholder satisfaction, financial factors have determined SOE's success. The present study simulates an SOE Fuzzy Comprehensive Evaluation approach to overcome the constraint. The model encompasses quantitative and qualitative performance. The proposed model prioritizes the whole evaluation aim and follows it with performance criteria and sub-criteria. This paper used the analytical hierarchy process with expert survey input to fine-tune the standard weights. Fuzzy logic addresses the uncertainty in qualitative analysis. This method performs traditional financial ratio analysis, balanced scorecard, and data envelope analysis
Appraisal of species composition and ecology of Drosophilids in the Lower Swat Valley, Pakistan
Authors: Rahman Hamid Ur , Hadi Gulalai
Published: October 2024

The drosophilid fauna of Pakistan remains largely understudied with numerous cities in the country yet to be thoroughly surveyed. This study aimed to investigate the drosophilid fauna of tehsil Babuzai in the Lower Swat Valley, Pakistan. The aerial net was used to collect flies from ten distinct locations within the tehsil. The specimens underwent dry preservation and subsequently analyzed using a digital microscope. Five distinct species were identified, all classified into two distinct genera within the family Drosophilidae. The taxa mentioned include Drosophila melanogaster, Drosophila immigrans, Drosophila willistoni, Drosophila hydei, and Zaprionus indianus. The present study reports that D. melanogaster exhibits a wider distribution than that of Z. indianus. The subsequent species in the distribution sequence was D. willistoni, whereas D. hydei and D. immigrans exhibited equivalent distribution patterns. The daily study of the flies' habitat ecology revealed that their population peaked during low temperatures and high humidity. Dipteran insects were gathered from diverse fruit sources, and it was noted that they exhibited no preference for specific hosts. Drosophila melanogaster and D. immigrans were widely distributed and documented in all surveyed areas of Pakistan. The three remaining species showed a non-cosmopolitan distribution, and their inclusion in the present study indicates that the Swat Valley possesses favorable climatic conditions for their proliferation.
Otra vuelta sobre dale y meta: eventos, cuantificación y aspecto
Authors: Kornfeld Laura Malena
Published: October 2024

El presente artículo se propone analizar desde el punto de vista descriptivo y teórico las formas verbales gramaticalizadas meta y dale, en particular en la combinación con infinitivos (e.g., Meta/ Dale charlar ese día), donde su comportamiento es el propio de un operador aspectual con significado durativo o iterativo (tal como aquí discutiremos), ya que puede ser asimilado al de auxiliares de perífrasis (Di Tullio, 2006). En este trabajo intentaremos determinar la distribución, la semántica y el análisis sintáctico de meta y dale en diversos tipos de cláusulas con infinitivo, pero también en su combinación con nombres (e.g., meta charla) y construcciones preposicionales (e.g., meta a la charla, dale con la charla). El interés descriptivo de esta indagación reside en que, con la excepción de Di Tullio (2006), solo habían sido tratados tangencialmente por la bibliografía, presumiblemente por su condición de recursos acotados a ciertas variedades del español americano (como el español de la Argentina). Desde un punto de vista teórico, esperamos que un análisis sistemático de las diversas construcciones que involucran a estos operadores suponga un aporte significativo a la discusión sobre las relaciones entre conceptos tan relevantes para la gramática como el aspecto gramatical, el aspecto léxico, la cuantificación, la intensificación y la ponderación.
El pretérito perfecto compuesto en contextos de aoristo en el español de Catamarca, Argentina
Authors: Seco María Alejandra
Published: October 2024

En este artículo analizamos la variación entre el pretérito perfecto simple (canté) y el pretérito perfecto compuesto (he cantado) en el español hablado en Catamarca (Argentina). A partir de un corpus de entrevistas semidirigidas a hablantes catamarqueños, divididos por edad y grado de instrucción formal, observamos la frecuencia de uso de cada tiempo y su distribución en la muestra, en relación con estos parámetros. Luego, nos centramos en el análisis de los registros del pretérito perfecto compuesto (PPC) en contextos de aoristo, con el objetivo de aportar datos para esta región poco explorada hasta el momento. Sostenemos que pueden encontrarse usos del PPC como aoristo, es decir, que funcionan como base de secuencias narrativas y que admiten adjuntos de localización temporal específica en el pasado, concentrados en los grupos de hablantes de mayor edad y menor grado de instrucción formal. En cambio, en los grupos más jóvenes y con mayor grado de instrucción, prevalece ampliamente el uso de la forma simple (PPS). Proponemos que esta distribución se debe a que el uso del PPC está sufriendo un proceso de retracción como consecuencia del avance del PPS, como la forma más prestigiosa, por la incidencia de la variedad rioplatense en el noroeste argentino.

Published: October 2024

Sound is a persistent yet dynamic component of the marine environment, reflecting both physical and biological properties. Whereas light can only travel tens of meters in the ocean, sound is able to travel tens to thousands of kilometers under certain conditions, revealing information at specific times and places. In addition, underwater sound provides opportunities for sustainable development and blue economy growth that aren’t readily available with other technologies. For example, the melting rate of Arctic ice and the health of coral reefs can be estimated from acoustic measurements (Becker et al., 2023). However, underwater acoustics is a complex topic, requiring specialized education and equipment. To expand the capacity of underwater acousticians requires dedicated educational opportunities and low-cost equipment and analysis resources.
Kefalet Sözleşmesinin Şekli Geçerlilik Şartları ve Ticaret Hukuku Açısından Özellik Arz Eden Hususlar
Authors: Güner Temel
Published: October 2024

Türk Borçlar Kanunu (TBK) m. 12/1 gereği, sözleşmelerin geçerliliği kural olarak şekle tabi değildir. Ancak özelikle ivazsız olarak sorumluluk altına giren zayıf konumdaki kişileri korumak, onları sorumluluk altına girmeden önce bir kez daha düşünmeye sevk etmek amacıyla bazı sözleşmeler şekle tabi tutulmuştur. Bu bağlamda şekle tabi tutulan sözleşmelerden birisi de kefalet sözleşmesidir. Kefalet sözleşmesinin geçerli olabilmesi için yazılı şekilde akdedilmesi, sorumlu olunacak azami miktarın, kefalet tarihinin ve müteselsil kefalet söz konusu ise buna ilişkin iradenin kefilin el yazısı ile yazılması gerekmektedir (TBK m. 583/1). Ayrıca kefil olan kişi evli ise eşin rızası alınmalıdır (TBK m. 584). Şekle ilişkin bu şartlar bütün kefalet sözleşmeleri için geçerlidir. Ancak bu şartların uygulama alanı ticaret hukuku açısından özellik arz edebilmektedir. Nitekim TBK m. 584/3’te, ticari işletme ile ilgili işletme sahibi; ticaret şirketleri ile ilgili ortak ve yöneticiler tarafından verilen kefaletlerde eşin rızasının aranmayacağı öngörülmüştür. Ayrıca TBK m. 603’te, kefaletin şekline, kefil olma ehliyetine ve eşin rızasına ilişkin şartların, gerçek kişilerce, kişisel güvence verilmesine ilişkin olarak başka ad altında akdedilen diğer sözleşmelerde de aranacağı öngörülmüştür. Bu noktada avalin de TBK m. 603 kapsamında değerlendirilip değerlendirilmeyeceği sorusu gündeme gelmektedir. Yine Türk Ticaret Kanunu (TTK) m. 7/2’de, ticari işlerde müteselsil kefalet karinesi öngörüldüğünden, ticari işlerde müteselsil kefaletin söz konusu olabilmesi için buna ilişkin iradenin kefilin el yazısı ile yazılmasının gerekli olup olmadığı sorusu gündeme gelmektedir. Çalışmamızda kefalet sözleşmesinin şekli geçerlilik şartları ve bu şartların ticaret hukuku açısından özellik arz eden durumları incelenmiştir.
Canine Genetics and Epidemiology of Behavior in Dogs
Authors: Amfim Adriana , Cătălina Bercea Livia , Cucu Natalia
Published: October 2024

According to Acheson Roy, the constant aim in epidemiology is that of answering the question ‘why did this individual develop this disease in this moment of time?.’ Similar to studies applied in classical epidemiology, observational epidemiological studies in genetics are divided into descriptive and analytical. Descriptive studies verify the variance model of the disease or behavior and can offer clues about the involvement of genetic or environmental factors. Analytical studies establish the causal effect (genetic cause) on the disease or behavior phenotype; in the case of an existing genetic cause, it remains to be identified. An analytic study model would be appropriate for the analysis of idiopathic aggressivity and epilepsy in dogs. In some cases, common etiological factors can be the basis of both situations. One such potential factor can be changes in dopaminergic function codified by the SLC6A3 gene. In the central nervous system of mammals, dopamine is a key neurotransmitter involved in locomotory activity, objectives, and reward processing-oriented behavior, as well as in convulsive activity.
Molecular Profiling of Follicular Helper T-Cell Lymphomas
Authors: Etebari Maryam , Navari Mohsen , Paolo Piccaluga Pier
Published: October 2024

Follicular helper T-cell Lymphomas (FH-TCL) refers to a group of peripheral T-cell lymphomas (PTCLs) that phenotypically shows T follicular helper cell markers. These tumors morphologically are heterogeneous and correspond to angioimmunoblastic T-cell lymphoma (AITL), follicular helper T-cell lymphoma, follicular type (FTCL), and a subset of nodal PTCL/NOS with TFH phenotype (FH-TCL/NOS), all included in a same chapter since 2017 in the two latest Editions of the WHO Classification. Though these three groups of PTCLs share some biological and clinicopathological features, their correlation at transcriptome level is still uncertain. While some authors suggest that FTCLs might actually be a part of AITL spectrum, some consider them solely to share common origin. In order to improve our understanding of the matter, we studied the correlation of these lymphomas based on their global gene expression profiles. Our results suggest that FTCLs, similar to FH-TCL/NOS, show a molecular profile distinct from AITL. Furthermore, we suggest that differences in molecular signatures of FTCL and AILT might be related to differences in their master transcription regulators. We conclude that our data support the most recent WHO classification, maintaining distinct the three groups of FH-TCL though under a same chapter.

Published: October 2024

The purpose of this research is to identify strategies to enhance school effectiveness by strengthening transformational leadership, interpersonal communication, ICT literacy, and knowledge management. A quantitative method with path analysis was applied, and SITOREM analysis was used to optimize each indicator. The study involved 445 teachers from private vocational schools in Depok City, with a sample of 211 teachers. The findings reveal that school effectiveness can be improved by reinforcing transformational leadership, interpersonal communication, ICT literacy, and knowledge management. Key strategies include addressing weak indicators such as feedback, empathy, knowledge application, and access. Statistical tests show significant positive direct effects of: 1) transformational leadership on school effectiveness (Sig=0.032), 2) interpersonal communication on school effectiveness (Sig=0.000), 3) ICT literacy on school effectiveness (Sig=0.001), and 4) knowledge management on school effectiveness (Sig=0.001). Additionally, transformational leadership, interpersonal communication, and ICT literacy all positively affect knowledge management. Knowledge management serves as an effective mediator for the influence of transformational leadership (Sig=0.004) and interpersonal communication (Sig=0.001) on school effectiveness, but not for ICT literacy (Sig=0.356).

Los desafíos mundiales asociados a la contaminación plástica intensifican la necesidad imperante de encontrar soluciones sostenibles en lugar de depender exclusivamente de plásticos convencionales. En este escenario, la explotación eficiente de los desechos generados por la industria cangrejera emerge como un enfoque prometedor para obtener quitosano, un biopolímero que destaca por su versatilidad y su naturaleza respetuosa con el medio ambiente. Varios estudios han resaltado las características singulares del quitosano, incluyendo su biodegradabilidad, biocompatibilidad en aplicaciones biotecnológicas. Investigaciones anteriores han examinado su utilización en una variedad de sectores, desde el ámbito médico hasta el alimentario, evidenciando su capacidad para enfrentar desafíos ambientales y fomentar la sostenibilidad. El uso del quitosano como biopolímero procedente de cangrejo para potenciales aplicaciones como la bioremedicación de cuerpos de agua o la obtención de plásticos biodegrables se basó en la despigmentación, desmineralización, desproteinización y desacetilación. Es de importancia, la incorporación del quitosano en procesos de depuración de aguas residuales como sustituto del sulfato de aluminio o en la fabricación de plásticos biodegradables se presenta como un área de investigación prometedora y pertinente. Además, se concluyó con éxito la extracción de quitosano mediante la caracterización, logrando un quitosano con un porcentaje de desacetilación del 56.1% obtenidos por FTIR este logro representa un paso significativo hacia la utilización efectiva de recursos renovables en la producción de materiales sostenibles, contribuyendo a la mitigación de la contaminación plástica y al fomento de prácticas más respetuosas con el medio ambiente.

The Effects of Unethical Practices on the Burnout Level of Accounting Professionals and an Implementation in Bursa Province
Authors: Yücel Elif , Zarper Ali
Published: October 2024

Burnout, which hinders individuals from performing their professions by complicating both work and social life, is also common in the accounting profession due to factors such as the large number of communication parties, intense work pace, and the mentally demanding nature of the job. Given that burnout experienced by accountants is a significant issue affecting many parties, it is essential to evaluate the factors contributing to this condition. Among these factors are unethical practices encountered in the profession. Accountants frequently face ethical dilemmas due to their responsibilities to various stakeholders. This study, designed to determine the impact of unethical practices on accountants' burnout levels, gathered insights from CPAs via surveys and analyzed them using statistical methods. The analysis revealed that accountants experience a significant decline in personal accomplishment and, to a lesser extent, emotional exhaustion, but do not become desensitized to the profession.
Computing aerodynamic damping in roll and pitch of a supersonic finner model

Published: October 2024

Accurate aerodynamic coefficients and their derivatives are crucial for flight dynamics analysis and appropriate control definition. Even when the investigated geometry is simple (e.g. a revolution body, with simple control or stabilizing surfaces), determination of its aerodynamic derivatives, particularly at supersonic regimes, is rather challenging, and usually includes extensive computational and experimental campaigns. This paper computationally investigates quasi-steady or unsteady supersonic flows that include rigid body motion effects around the Army-Navy Finner geometry (a basic, revolution body with L/D = 10 fineness, slender, conical nose section, and wedge-section fins in × configuration). To elucidate the flow fields, the Reynolds-averaged Navier-Stokes equations are closed by k-o SST turbulence model. Roll and pitch damping are estimated by different approaches, and the obtained values are compared mutually, but also to the available experimental data. In addition, some representative flow visualizations are included.

The fast-moving technologies have enabled many new applications of Unmanned Aerial Vehicles for military and commercial purposes. This technology improvement has opened an incredible number of new opportunities for UAVs to be used for a variety of societal challenges. Despite the considerable investments and operational success, the nonconventional UAV design has not been well documented in the literature. In this paper, the nonconventional X-tail design will be evaluated. Control derivative estimation has been done by different methods.
The effectivnes of the use of drones in modern conflict

Published: October 2024

We are witnessing armies participating in the conflict posting videos on social media depicting drones as cheap weapons that can effectively destroy expensive artillery pieces or tanks worth millions of dollars. Drones have transformed from performing specialized functions into one of the most important and widespread weapons on the battlefield. The deployment of smaller drones, which was inconsistent at the beginning of the war, has now become extremely organized. Almost every combat brigade has a company of attack drones, while most units have small reconnaissance drones. If we are at the beginning of the drone revolution, world politics will change dramatically in the near future. If the drone revolution is in the making, states will have to significantly revise their defense policies. Troops on the battlefield will become increasingly vulnerable and all states will have to restructure their armed forces away from expensive and complex military platforms in favor of new, less sophisticated and cheaper technologies such as drones. However, drone technology is most effective when used in conjunction with other types of weapons.
Failure analysis of aircraft structural elements

Published: October 2024

The attention in the work is focused on the strength analysis of the vital elements of the aircraft structure. Special attention is focused on defining critical locations from the aspect of possible failures during exploitation. Then, initial damage in the form of initial cracking is assumed in the defined critical zone. The assumed crack sizes are in accordance with the recommendation on allowable damages. For the cracks defined in this way and the corresponding load spectrum, the propagation of the crack until the effective fracture is analyzed. Different crack propagation laws can be used for this purpose. In this paper, the various models were used. The finite element method (FEM) was used for the structural analysis, where special 6-node singular finite elements were used around the crack tip. Since there are always peaks within the real load spectrum, they are modeled using in-house software. This paper deals with research in the domain of estimating the failure of aircraft structures in critical locations under the effect of cyclic loads. The main goal is to provide an efficient computation method. The previous method is illustrated on the analysis of the failure of parts of vital connections of aircraft structures.
