The necessity of developing digital technologies for managing biotechnological processes in long-term agrocenoses based on cognitive modeling is substantiated. Methodological approaches to the construction of effective management tools for biotechnological processes based on the logical concept of the triad (organization, management, efficiency) in a dynamic cycle have been developed. An algorithm for the formation of digital technologies for managing biotechnological processes is proposed, including: the formation of multifunctional databases and data banks and digital applications, cognitive modeling of system relationships and the formation of cognitive maps, the development of a system architecture of a prototype program, approbation and verification of the adequacy of a digital application. An algorithm has been developed for constructing cognitive models for the formation of management tools for biotechnological processes in long-term agrocenoses, including clarification of goal setting and local tasks; the distribution of functional relationships between the structural components of the agrocenosis using methods of correlation and regression analysis; economic and statistical characteristics of systemic relationships in reproductive processes by functional areas of influence using correlation matrices and discriminant analysis; verification of the results of optimization of parameters of functional stability and technological and economic efficiency of production and technological processes. A cognitive process management map is constructed using the example of protecting fruit plantations from pests. A flowchart of an algorithm for building a digital control program for biotechnological processes for protecting fruit plantations is proposed using the example of an apple moth, which provides for the development of a technology for importing data from a weather station to determine the sum of effective temperatures and determine the start of processing depending on the stage of development of the pest; neural network technologies for detecting a harmful object; a module for automated selection of a protection system.

The article contains a review of literature sources reporting on the relevance of agrochemical monitoring of ampelocenosis soils in conditions of intensification of production, prospects for mechanized sampling of agricultural soils for chemical analysis of samples, assessment of the level of effective fertility and "health" of soils of agrocenoses, as well as a comparative analysis of manual and mechanized methods of soil sampling. The characteristics of automatic samplers for agriculture are given. Based on the results of experimental data presented by researchers in the literature, for a number of years, a production test of the effectiveness of a mechanized method of soil sampling in various agrocenoses was carried out using a Tornomar CH-200 hydraulic soil sampler, adaptation of the method in accordance with GOST R 58595-2019, analysis of the results of laboratory studies, creation of a database “db. Agrosoil”. Mechanized soil sampling was carried out in conditions of chernozem soils in non-irrigated field crop rotations on an area of more than 850 hectares and sod-carbonate soils on sites of various configurations (including on slopes) with a total area of more than 100 hectares before laying vineyards. Soil samples were taken using the Tornomar CH-200 sampler in the stationary state of the unit evenly along the route. Mixed soil samples weighing at least 400 g consisted of 7-10 point samples. The timing of the mechanized sampling of soil samples in the flat areas of the field crop rotation confirmed the previously established significant reduction in the time spent on the survey by more than 5 times covering a significant area. Labor productivity using the Tornomar CH-200 sampler on more difficult slope areas, according to timekeeping data, increased more than 4 times. The formed database based on the results of the survey will allow effective monitoring of soil fertility of ampelocenoses in selected control areas and promptly carry out measures to increase it and predict possible changes over time.

Juice yield is a very important characteristic of pomegranate fruits (Punica granatum L.) in economic terms. In this study, the limits of variability of morphological and technological characteristics of fruits of 25 varieties and forms of pomegranate from Geokchai (Azerbaijan) were studied. The values of these features were determined using the weight method. An attempt was also made to establish the nature of the formation of the ratio between the individual parts of the fruit using the method of biological statistics. The results showed that the studied varieties and forms can be grouped into three different groups, taking into account the changing balance between individual parts of the fruit during its active growth and development on the tree. In the fruits of one group of the studied varieties and forms, the increase in the total mass of the rind and bare seeds was slower than the increase in the mass of the juice. 5 medium-fruited varieties and forms with juice yield from ripe fruits averaging 53.2 % of their total weight were assigned to this group. The other two groups included 7 small-fruited and 13 large-fruited varieties and forms, in which this indicator was significantly lower (juice yield 45.4 and 43.1 %, respectively). Thus, it is the medium size fruit (and not the large size fruit, as is now customary) that should serve as the main phenotypic feature – a guideline when choosing juice material from existing varieties and creating new pomegranate juice varieties. This result can be included in the instructions for processors of this specific raw material and guidelines for breeders working towards the creation of new juice varieties of pomegranate.

Agriculture has a negative impact on environmental components. This exposure is mainly due to the use of pesticides, fertilizers and other toxic agricultural chemicals. And wine production is no exception, the process of growing grapes and processing them into wine also contributes to these effects. Using a method called life cycle assessment (LCA), the impact on environmental components of the life cycle of various products can be assessed and compared. In this article, we present some of the main stages of the wine's life cycle. To determine the environmental impact of an agricultural product, it is necessary to conduct a life cycle analysis of an individual product. The life cycle of wine production is divided into the following stages: production, transportation, storage, processing and completion of the product life cycle – consumption. The purpose of the study is to assess the impact of the winery on the environment. In the course of the research, methods were used to assess the impact of the life cycle of food products on environmental components: the method of balance schemes and the method of relevant tables (ABC-analysis), which allow taking into account incoming (raw materials, resources, including fuel and energy), outgoing (solid waste, gas emissions, wastewater) and risky environmental aspects. For comparative analysis, methods have been developed to assess the impact of the life cycle of wine products obtained by traditional and biodynamic methods on environmental components. It has been revealed that solid and liquid waste products have the greatest negative impact on the environment. The results obtained are aimed at improving the environmental safety of the enterprise and reducing its harmful effects on the environment.

The article presents the results of research for 2020-2022 on the collection and mother site in the village of Uch-Dere. Differences in the weather conditions of tea bushes growing in humid subtropics of Russia with a natural habitat (China) have been determined. Tea plants in the humid subtropics of Russia are more susceptible to stress factors. Due to weather conditions during the growing season (from April to September), where the main leaf period lasts four months (from May to August inclusive). In China, on the contrary, the tea leaf harvest period lasts from April to September and occurs more smoothly due to some differences in weather conditions. Temperature fluctuations in China and in the humid subtropics of Russia are similar, but there are differences in the phase of the active temperature of more than 10 ºС, by month. A steady transition through 10 ºС in the subtropics of Russia is 2-3 decades of April, and in China it is 2-3 decades of March, which allows to start collecting flushes in April. Further, by month, the temperature regime between China and Russia is leveled and the difference in the amount of flushes by month depends only on the amount of precipitation. So, in China, the main precipitation intake is spring 41 %, summer – 34 %, winter and autumn account for 9 % and 16 % of the total annual intake. Therefore, the productive period of receipt of tea leaves in China begins in April and ends in September. Another trend of precipitation distribution in the subtropics of Russia. The main intake occurs in winter and autumn (33.1 % and 28.0 %) during the period of relative rest, which subsequently negatively affects the regrowth of flushes (productive shoots).

Впервые экспериментально продемонстрирована возможность усиления ударной волны в двухфазной смеси перегретого водяного пара и жидкого триэтилалюминия (ТЭА, Al(C2H5)3). Показано, что тонкая синхронизация момента впрыска ТЭА в поток перегретого водяного пара с моментом прихода затухающей ударной волны позволяет обеспечить незатухающий характер распространения ударной волны в двухфазной среде перегретый водяной пар - ТЭА со скоростью на уровне 1500-1700 м/с. Такой уровень скорости согласуется с термодинамическим расчетом для скорости детонации в обедненной горючим смеси перегретого водяного пара с ТЭА. Поскольку зарегистрированные в экспериментах профили давления в целом не соответствуют профилю давления в детонационной волне, утверждать, что получен переход ударной волны в детонацию пока преждевременно.

Published: June 2024

The positive online behavior effects of digital citizenship have increasingly attracted the attention of scholars. This study designed and tested the psychometric properties of an Adolescent Digital Citizenship Scale (DCS-A) in two independent samples of Mexican secondary students (Sample 1, M age = 13.2 years, SD = 1.5 and Sample 2, M age = 13.4 years, SD = 1.4; N1 = 750, N2 = 750). We examined content, factorial, discriminant, concurrent validity, and reliability. We also tested the cross-sample and gender invariance. Confirmatory factor analysis (CFA) demonstrated goodness-of-fit on a second-order factorial model that displays three first-order factors (online ethic, online civic engagement, and online diversity acceptance). Cross-validation confirmed the factorial structure stability of the DCS-A across the independent sample. The result demonstrated the equivalence of the measurement model in both genders (configural, metric, and scalar invariance). The latent means comparison indicates that females held greater online ethics, online civic engagement, and online inclusive behaviors than males. Finally, the concurrent validity of the scale was supported by finding a positive relationship between DCS-A dimensions and defender behavior and a negative association with passive and reinforces interventions in cyberbullying events. These results suggest that the DCS-A is a theoretically and psychometrically grounded measure of digital citizenship in adolescents.
Actitudes del profesorado de formación vial en formación para educar personas conductoras con riesgo cero

Published: June 2024

Existen escasas investigaciones sobre las actitudes del profesorado de formación vial hacia la enseñanza de la conducción segura. Los datos sobre accidentalidad muestran la necesidad de investigar sobre el papel de este profesional en la capacitación de personas conductoras, puesto que a nivel internacional la educación destaca por ser una herramienta imprescindible para mejorar la seguridad vial. Se ha aplicado un cuestionario para evaluar la predisposición a la enseñanza de la conducción segura (EPRECONS) del profesorado a una muestra de 378 aspirantes en formación. Los resultados muestran que el cuestionario tiene buenas propiedades psicométricas.  Los 9 factores que lo integran contribuyen a explicar la variable dependiente, aunque los que mejor lo hacen son: “anticipación al riesgo”, “práctica de conducción segura” y “control social de riesgos”, todos ellos relacionados con el comportamiento de la persona como conductora. Se visualizan algunas diferencias en los modelos por sexo: en los hombres la predisposición a formar personas conductoras seguras se explica principalmente por el factor “práctica de conducción segura”, mientras que en las mujeres por el factor “anticipación al riesgo”. Las profesoras muestran mayor nivel de seguridad en “alcohol y conducción” y mayores niveles competenciales en “transmisión de sentimientos”. Los resultados obtenidos suponen un notable avance por su contribución en el diseño de acciones formativas relacionadas con la formación de estos profesionales y permiten considerarlos como modelos docentes que inciden en la formación inicial de personas conductoras seguras, favoreciendo así, la reducción de la siniestralidad y avanzando hacia el riesgo cero.

Published: June 2024

This paper analyses the result of applying podcasts as a teaching-learning tool for university students. Using a quantitative methodology, with a descriptive and correlational design, Levene's inferential t-test for equality of variances was used to compare two groups of students to assess if there are differences regarding the academic, design, usability and learning variables, in order to verify the differences between students creating the contents and those only listening to the end result. A sample of 461 students was used in this research, distributed in two groups. In the first group, the teaching staff oversaw preparing and carrying out the dynamics of the podcast. In the second group, the students collaboratively created the podcast. To analyse the differences between the two groups, the Educational Innovation Questionnaire (CINNE) was applied, based on the Podcast Evaluation Questionnaire, QAEP (Alarcón and Blanca, 2020), and the SUS Scale (Brooke, 2013). The results indicate significant differences (99.95% CI 99.95%) between the groups in the usability and design dimensions. No gender differences were found. In conclusion, this research paper has confirmed the effectiveness of using podcasts as a didactic strategy, in particular regarding its accessibility, use, and design by students.

Published: June 2024

El entorno laboral de los educadores sociales de centros de menores es complejo, siendo un desafío adicional atender a los perfiles con múltiples dificultades que presentan los menores. En este contexto, ciertas variables relacionadas con su desarrollo afectivo y sus competencias emocionales podrían desempeñar un papel crucial en la efectiva gestión de su trabajo. Esta investigación explora las relaciones entre los estilos de apego, la inteligencia emocional y el compromiso laboral en educadores sociales de centros de menores en riesgo de exclusión social de Andalucía. Los resultados revelaron patrones significativos de asociación entre estilos de apego formados durante la infancia de los educadores de menores y la inteligencia emocional. Se observó que los educadores con un apego seguro se perciben con una alta habilidad para manejar sus emociones, mientras que aquellos con un apego inseguro se percibían con niveles más bajos. El estilo de apego seguro no tuvo un impacto directo en sus niveles de compromiso laboral. En cambio, los profesionales que se perciben con una alta habilidad para regular de manera inteligente sus emociones tuvieron niveles mayores de compromiso en sus funciones laborales. Estos hallazgos sugieren que la relación del apego con la inteligencia emocional y de esta con el compromiso laboral, desempeñan un papel crucial en los niveles de energía, entusiasmo y dedicación de los educadores sociales en contextos de atención a menores en riesgo de exclusión social, teniendo implicaciones importantes para el diseño de intervenciones socioemocionales y programas de apoyo en el ámbito laboral de estos profesionales.
Los impactos subjetivos de la desaparición de personas en el norte de Veracruz, México
Authors: Márquez Verduzco David
Published: June 2024

La desaparición de personas ha sido una de las manifestaciones más ominosas de la violencia en México iniciada a partir de la “Guerra contra el narcotráfico” en el año 2006. Este trabajo pretende dar cuenta de la particularidad de la desaparición de personas en un contexto situado. Inicialmente, se explicitará el marco teórico y el concepto de subjetividad del cual se parte para, después, dar paso a un recorrido histórico-social de la violencia en México e insertar la desaparición de personas como una forma extrema de ésta. A partir de ello, se describirá el contexto situado y la significación particular de la desaparición en el norte de Veracruz, México, a través del acompañamiento psicosocial realizado, consistente en trabajo etnográfico y de entrevistas, además de contención emocional. Se discute sobre los impactos que la desaparición ha dejado en esta zona de México, así como la importancia de los colectivos de familiares de personas desaparecidas para hacer frente a la violencia.
Silent rifles? Criminal agendas and paramilitary demobilization in Colombia under the Peace Triangle
Authors: Arratia Sandoval Esteban
Published: June 2024

How do criminal agendas affect a peace process with violent non-state actors? This article attempts to resolve this question by presenting a qualitative analysis of the demobilization process of the United Self-Defense Forces of Colombia (AUC) during the government of Alvaro Uribe using the Peace Triangle as an analytical framework, based on three study variables: issues, behavior and attitudes.The review from this model aims to make a double contribution to peace studies. On the one hand, it fills a gap in academic knowledge about the sustainability of peace processes. And, on the other, to examine the relationship between criminal agendas and conflict resolution. The research reveals that the former Colombian President's inadequate management of criminal agendas transformed the peace negotiation into a damage control strategy since it did not intend to modify the scale of predatory crimes committed by the AUC, but rather to shape its behavior

Published: June 2024

With solely academic knowledge, it appears challenging for today's students to find a place for themselves in the business world where they will operate in the future. Therefore, it is crucial to provide students with a variety of abilities, such as problem-solving, critical thinking, creativity, collaboration, and analytical thinking, in addition to academic knowledge. The STEM education approach is one of the approaches that aims to equip students with the knowledge and abilities they need in the fields of science, technology, engineering, and mathematics while also educating them as persons with 21st-century competencies. In this context, it is the teachers who will provide students with these knowledge and skills and apply STEM education. In this sense, it is thought that teachers' knowledge and competencies in STEM teaching are significant. In this study, it was aimed to determine the STEM teaching competencies of pre-service teachers studying in the last year of education faculties. The case study design, one of the qualitative research methods, was used in the research. The study group of the research consists of 45 final year science and classroom teaching students studying at 21 different universities in Turkey. The data of the research was obtained by the "STEM Teaching Competencies Questionnaire" developed by the researchers. The obtained data were analyzed simultaneously by three different researchers using content analysis. During the analysis process, codes, categories and themes were created. As a result, it can be claimed that pre-service teachers have theoretical knowledge of STEM education, but they do not think of themselves as highly competent. They require more hands-on education and wish to use it when they begin their careers, but they need practice-based education for this

Paradoxical sleep deprivation (PSD) or sleep disorders can affect sexual function and potentially reduce fertility rates. The active substance of Purwoceng (Pimpinella pruatjan Molk.), namely flavonoid and tannin compounds can improve the quality of function. Drug nanoemulsion is expected to increase the therapeutic effect and reduce toxicity. This study aims to determine the effect of purwoceng nanoemulsion on serum testosterone levels, testicular volume and testicular histopathology of male Wistar rats after stress induction of paradoxical sleep deprivation for 96 hours. This research is an experimental study with a post-test only design with a control group. A total of 24 rats were divided into 6 treatment groups. Group A was given PSD, group B was given PSD and sleep recovery, group C was given PSD and purwoceng extract 25 mg/300 gBW/day, group D was given PSD and purwoceng nanoemulsion 25 mg/300 gBW/day, group E was given PSD and purwoceng nanoemulsion. 50 mg/300 gBW/day, and group F was given PSD and purwoceng nanoemulsion 75 mg/300 gBW/day. Serum testosterone levels were measured by the ELISA method,  testicular volume and histopathology determined using Image J software and data were analyzed by One Way ANOVA test and followed by Post Hoc Bonferroni test. Statistical analysis showed that there were significant differences in serum testosterone levels, testicular volume and testicular histopathology (p<0.005). Administration of purwoceng nanoemulsion affects serum testosterone levels, testicular volume, and testicular histopathology after PSD induction
The nexus between information sources, gender and adoption of fall armyworm management practices in Southern Ghana
Authors: Ngissah Ebenezer
Published: June 2024

The impact of Fall Army Worm (FAW) infestation on the livelihood outcomes of farmers in Africa is an issue of critical concern. Specificities of information sources and their efficacy in the management of Fall Armyworm remain crucial. Yet still, the nexus between farmers’ information sources and the management of Fall Armyworm appears scarce in the related literature pertaining to the global south. This article answers the research question: What is the relationship between specific information sources and the management practices of Fall Army Worm in Ghana? Using cross-sectional data on 340 smallholder farmers, the findings showed that information derived from peer farmers, Agricultural extension officers, and the media related to the adoption of fall armyworm management practices. Additionally, information from agricultural extension agents has a significant relationship with the use of pesticides, handpicking, and frequent weeding. Generally, the majority (97%) of smallholder farmers remained aware of the presence of FAW and had been negatively affected. We recommend that peer-to-peer extension be harnessed and scaled up in the dissemination of useful agricultural information given the shortfall in adequate agricultural extension officers in Ghana and most countries in Sub-Saharan Africa.

It is shown that during this period it had fluctuating trends: the deviation between the minimum and maximum values was 109 million tonnes (7.7 %) for iron and 112 million tonnes (5.7 %) for steel. Domestic steel production in 2019-2021 was characterised by an increase of 1.1 million tonnes (5.2 %) in iron and fluctuations (the deviation was 0.8 million tonnes, i.e. 3.7 %) in steel, and a sharp decrease of 14.8 million tonnes (69.7 %) in steel. t (69.8 %) for iron and 15.1 million tonnes (70.6 %) for steel in 2022 and a further decrease of 0.4 million tonnes (6.2 %) for iron and 0.1 million tonnes (1.6 %) for steel in 2023 is due to the consequences of Russia's armed aggression against Ukraine. The article considers and analyses the volumes of global production of metallurgical coke in 20192021. It is shown that during this period it had fluctuating trends: the deviation was 21 million tonnes (3.0 %). The volume of coke production in China in 2020-2023 increased at an average annual growth rate of 2.2, 2.4, and 3.8 %, respectively. Domestic production of metallurgical coke in 20192021 was characterised by a decrease in volume by 0.44 million tonnes (5.2 %), and a rapid decrease by 5.6 million tonnes (59.0 %) in 2022 is also due to the consequences of armed aggression. Separate forecasts for global metallurgical coke production in the short and long term are considered. It is shown that there is no consensus on the development of global coke production. The most negative scenario is a decline in global coke production to $84.016 billion (USD) in 2029, while the most positive is an increase to $325.78 billion in 2034. In 2024, on average, the global metallurgical coke market will be around $106 billion according to negative forecasts and around $205 billion according to positive forecasts. Given the World steel Association's weak positive outlook for global steel production, as well as the existing increase in coke production in China in 2020-2023 and the planned expansion of coke production capacity in India and Brazil, a restrained positive outlook for global coke production is most likely (for 2024 and beyond).

In an environment with unprecedented unemployment levels, entrepreneurship is promoted as an approach that has a potentially positive effect on the economy through innovation and employment creation. The objective of the current study was to determine entrepreneurial interest and intention among college students. This study examined the entrepreneurial tendencies of students registered for an entrepreneurship module in a college. The study was quantitative and used Caird’s General Enterprising Tendencies Questionnaire to collect information from students registered at the local college. The theory of planned behavior was utilized to explore whether, if the students have an interest in business, they are also inclined to act on that desire to participate in business undertakings. The results suggested that the students in the study possessed the tendency to be entrepreneurial and were keen to start businesses at some point in their lives. Yet, they mostly do not intend to start business ventures for several reasons, including fear of failure. The study contributes to the knowledge that underprivileged still contributes to a lack of entrepreneurial inclination, and support is paramount in nurturing that entrepreneurial interest. The study recommends that the college’s entrepreneurship education emphasizes information about reasonable small business prospects in the area; provide relevant information such as funding or registration, for the encouragement and advancement of especially youth-owned businesses; and host dialogues that should be delivered by young successful small business owners or managers.

Urban human-made environments present a range of potential benefits for wellbeing through their design. However, there is a lack of comprehensive organization on this topic. To this end, we performed a scoping review to provide an overview of how the urban environment, particularly its designed components, has been previously studied in relation to aesthetics and wellbeing. A total of 255 articles related to urban aesthetics were identified, of which 122 were also related to wellbeing. The results showed the frequency (most and least studied) and the diversity in the man-made components, aesthetic and wellbeing dimensions studied in relation to the urban environment within two decades. Our review highlights the need for consensus in terminology regarding the distinction between aesthetics and wellbeing concepts, and which terms/measures ought to be implemented more in environmental psychology research. All in all, we provide the basis for (1) researchers from various fields, who can use our findings to plan future studies, and (2) urban planners and designers alike, who can use our review to assess the aesthetic and wellbeing potential of urban elements for their designs; so that they can make our cities more aesthetically pleasing, better for wellbeing, and, fundamentally, better places to live.

Published: June 2024

The importance of solar photovoltaic (PV) systems has increased over the past ten years due to the solar PV industry's explosive growth. To ensure the reliable, safe, and efficient operation of residential PV systems, fault detection is crucial. Early classification of faults can improve PV system performance and reduce damage and energy loss. Many recent studies have focused on classifying and detecting PV faults but most of them are limited to specific reasons like Real-world data can be restricted, unbalanced, or include noise, all of which may decrease the effectiveness of ML models. This paper proposes a method for identifying and classifying both physical and electrical faults in the PV array system applying a machine learning (Random Forest) model to that is trained using a synthetic photovoltaic training database. Make use of a synthetic PV database opens the door to a more precise, effective, and scalable PV system by addressing the limitations of real-world data. MATLAB is used to create a synthetic database while scikit-learn tool in Jupyter Notebook is used to train an ML model are the two main steps in this paper. The performance of the proposed model is compared with the existing ML model and achieves the most effective algorithm offering higher accuracy in detection of 98.6% and classification accuracy is 94.2% for both physical and electrical faults after being successfully tested on real-world datasets and trained on historical data from the PV array system (PV Database).
An Efficient DC-AC Power Integration Model for Single-Phase Systems, Simulated in MATLAB

Published: June 2024

In the face of growing clean energy demands, this study presents a model for integrating Direct Current (DC) sources into the existing Alternating Current (AC) grid. The model is based on a single-phase system where a DC source is added. A converter, designed using the synchronous reference frame, is proposed to address integration issues. This converter allows for the control of both active and reactive power using a dq reference frame. A Proportional-Integrator (PI) controller is chosen for this purpose. To generate the necessary operational references, a Phase-Locked Loop (PLL) is used. An LCL filter is also incorporated based on its performance quality. The entire model is simulated in MATLAB, and the output obtained confirms the model’s ability to control both active and reactive power when integrating DC with AC and T. This work significantly contributes to the efforts of integrating clean energy into our existing grid systems.

Research on the military-technogenic burden on the natural environment as a result of international conflicts is relevant since military operations cause catastrophic consequences for the environment and natural resources, which can lead to irreversible disturbances in ecosystems. The study is devoted to the examination of the impact of military-technogenic loads on the soils of military training grounds. The paper considers methods of soil sampling and their analysis for the content of heavy metals and other chemical compounds and determines the impact of this load on the ecosystem and possible consequences for human health. The influence of military activity on the soil quality of military training grounds, in particular in the Cherkasy region, is analysed. The study includes the determination by X-ray fluorescence and atomic emission method of the content of various elements in the soil. The results showed a substantial iron content, which may be due to the use of explosives in military exercises. It is noted that despite the fact that exceeding the norms of maximum permissible content concentration, no heavy metals were recorded in the examined soils, and the maximum lead content approached the maximum permissible concentration, which requires further monitoring and control of this parameter. Ph determination showed a slightly acidic soil condition in combat exercise sites, which can affect plant fertility and growth. The content of nitrogen, phosphorus, potassium, and boron was assessed, and the results showed a lack of these nutrients for normal plant development. It is established that soil damage as a result of military operations can have a long-term negative impact and pose a threat to residents and territories. The results of the tests indicate a slight technogenic load at the sites of military exercises. The detected contamination of the examined samples is insubstantial, which indicates that the impact of military activities on the soil condition is limited. The results of the study will help to understand the possible health risks for people living near military training grounds and respond appropriately to protect their health

Published: June 2024

This research article presents a descriptive cross-sectional study titled "Workplace Violence among Nurses in a Hospital." The study was conducted at Nepalgunj Medical College Teaching Hospital in Banke as a partial fulfillment of the requirements for the Bachelor in Nursing Science Programme. The primary objectives of the study were to determine the prevalence of workplace violence among nurses in a hospital setting. A quantitative approach utilizing a non-probability purposive sampling technique with a sample size of 62 was used to collect data, and a semi-structured questionnaire was employed as the instrument for data collection. The collected data was analyzed using the statistical package for social sciences (SPSS) version 20, and the findings were analyzed with various descriptive statistics such as frequency and percentage. The results of the study indicated that half of the nurses (50%) reported experiencing some form of violence in their workplace. Verbal violence was found to be the most prevalent form of workplace violence, accounting for nearly half (43.5%) of the incidents, while physical violence was reported by only 9.7% of the nurses and sexual violence by 8.1%. These findings underscore the need for proactive measures to prevent and address workplace violence in healthcare settings, with a particular emphasis on preventing verbal abuse.

Published: June 2024

In our case, a newborn with FATCO (fibular Aplasia, Tibial Campomelia and Oligodactyly) syndrome is described. FATCO syndrome is a syndrome characterized by shortening and forward bending of the lower extremities at the distal third point of the tibia, standing oligodactyly and fibular aplasia. In our case, there was no other anomaly except extremity anomalies. The karyotype was normal male (46,XY). In addition to presenting a new case report of this syndrome, we would like to emphasize the importance of prenatal diagnosis and genetic counseling for families at high risk for genetic disease, especially in developing countries.
William of Tyr’ın Gözünden İslam ve Müslümanlar
Authors: Çekiç Ayşe
Published: June 2024

Ortaçağ, Batı dünyasının İslam ve Müslümanlar hakkında geniş kapsamlı veri ürettiği bir zaman dilimidir. Haçlı Seferleri tarihi ele alındığında belki de sürecin en mütekâmil kalem ehli sayılabilecek kişisi William of Tyr’dır. Historia Rerum in Partibus Transmarinis Gestarum adını verdiği 23 bölümden müteşekkil Haçlı Seferleri anlatısında yazar, İslam ve Müslümanlar hakkında kapsayıcı bilgiler aktarmaktadır. Haçlı tarih yazımının genel seyrinde İslam’a ve Müslümanlara karşı olumsuz bakış açısının zirve noktası sayılabilecek William’a göre İslam dini ve Müslümanlar uydurulmuş bir inanç sisteminin ürünüdür. Haçlı seferleri tarihinde İslam ve Müslümanları bu bakış açısıyla sistematik olarak tasnifleyen ve düşman olarak telakki eden yazarın anlatıları gerçekle örtüşmemektedir. Bu makale William’ın gözünden İslam ve Müslümanların konumunu ve hangi gerekçeyle ele alındığı kaygısını incelemektedir. Kaynak analizi yöntemiyle İslam ve Müslümanları tasvir eden anlatıların tasnifiyle yazarın zihnindeki profil anlamlandırılmaya çalışılmıştır. Sonuç itibariyle William’ın gözünden İslamiyet ve Müslümanların varlığının Haçlı seferlerini tetikleyen bir sürece tekabül etttiği sürecine ulaşılmıştır.
