Urban soil survey is necessary in terms of asses the life quality of their inhabitants. From this point of view the detection of the ecological risk in urban soils was done. At first fifteen samples were collected from a depth 0-30cm, in Košice city, Eastern Slovakia around the lake located in the residential zone. In collected samples potential toxic trace elements were established and also the presence of soil organic matter (SOM) was studied, because at present the SOM was recognized as an indicator of sustainable development in the frame of the UN Agenda 2030. SOM and soil organic carbon (SOC) have a positive effect on soil chemical, physical and biological properties. The pH of all studied samples was estimated in the range 6.83-7.42. For rapid screening were used following methods: X-ray fluorescence spectrometry (XRF) and total organic carbon (TOC) analysis. SOM was determined by calculation from the SOC amount. On the basis of XRF analysis it was found that the permitted limits for the elements Co, Ni, Cu, Zn, As were largely exceeded.

A soil has been of great concern throughout the world due to increasing environmental awareness and interest in the quality and management of such soils. Košice, the city in eastern Slovakia, is exposed to typical urban contamination sources such, furthermore, being the largest steel producer in Central Europe, it is long-term environmentally loaded by the iron and steel works that represent the largest source of (metallic elements) contamination in Slovakia. Five sampling sites located in the surrounding of U.S.Steel Košice (Slovakia), were selected, where almost all the agricultural soils were polluted by the metallic elements (Fe3+, Al3+, Mn2+, Cu2+, As3+). Agricultural soils toxicity was assessed with the toxicity bioassay -Phytotoxkit. Tests of limit concentrations of the elements (Fe3+, Al3+, Mn2+, Cu2+ and As3+) and Tests of soil concentration series (100-50-25-12.5%) - screening tests mustard Sinapis alba and Lepidium sativum were performed. The testing of the concentration range was performed in order to determine the values of 14d/EC50 and the possibility of comparing the ecotoxicity of metallic elements in agricultural soils (ISO 11269-2 Soil quality). Four concentrations were prepared in test plates: 12.5 - 25 - 50 - 100% soil samples. Concentration of metals in the soil samples ranged from 24400 to 39000 mg/kg for iron; 54000 to 85000 mg/kg for aluminum; 381 to 1035 mg/kg for manganese; 27 to 59 mg/kg for copper; and 7 to 36 mg/kg for arsenic. Based on the median concentration, the metals in the soils were arranged in the following decreasing order: Al3+ > Fe3+ > Mn2+ > Cu2+ > As3+. In the agricultural soils (4USS-PW) showed high contamination values for the iron with a median 35300 mg/kg, aluminum with a median 82500 mg/kg, manganese with a median 1027 mg/kg. The median level of arsenic in the soil (4USS-PW) was 34 mg/kg, this indicate higher concentration as the limit concentration is 25 mg/kg (Law No. 220/2004-2). Agricultural soils 1-3USS and 5USS showed less than 50% inhibition of the seed germination and root growth in the S.alba and L. sativum tests compared to the control, excepting of soil from 4USS plant west (values of the EC50 to 65%). Thus, the results of phytotoxicity tests were consistent with the chemical data. The rapid increase in urbanization, industrialization, human population, and traffic flow has resulted in the environment surrounding farmland ecosystems being critically contaminated by metallic elements.

Adequate management and protection of underground water resources is a desideratum of the current period of evolution as consumption, requirements and degree of impurity of fresh water is increasing with the development of human society. Also, the limited nature of continental fresh water resources requires additional protection measures for current resources, so the understanding and objective assessment of aquifers’ vulnerability degree in case of accidental pollution, represents the basis of environmental policies developed for the purpose of sustainable development of human communities. The study of the vulnerability degree of environmental factors and ecosystems that directly or indirectly interact with groundwater resources was carried out by analyzing groundwater quality indicators (BTEX) based on the vulnerability intervals established according to national legislation in force. The aquifers’ vulnerability degree the was evaluated for 3 possible scenarios of accidental pollution with petroleum products for a well field located in the south of Romania. The effects of BTEX compounds on ecosystems that directly or indirectly interact with groundwater were evaluated according to synergistic effects of xenobiotics, manifested at ecological niche level. The aim of the vulnerability degree study is for it to function as an analytical tool to identify areas vulnerable to pollution phenomenon and to develop the best measures to limit the phenomenon of contaminants’ transfer to other underground water bodies. Aquifers and ecosystems’ degree of vulnerability to external pressures is an integrated component of the environmental or ecotoxicological risk assessment process associated with the phenomenon of accidental pollution that may have effects on the quality of water stored in aquifers. Results of the conducted research are of interest for engineers and researchers who study the hydrological and hydrodynamic phenomena of underground water in order to develop and apply the best measures to reduce the impact caused by economic activities.

We are currently in the period of an intensive climate change, resulting from changes in the heat balance of the earth’s surface and causing an increase in the temperature of the lower troposphere levels. According to the latest IPCC report of 2021, it is human activity that has indisputably caused the increase in atmospheric concentrations of greenhouse gases, responsible for this process. The consequences of climate change under Polish conditions, apart from a rise in temperature especially in the spring and winter months, are also changes in the amount and distribution of precipitation totals. A slight increase in precipitation totals is observed, however heavy rainfall is significantly more frequent, interspersed with periods of droughts and heatwaves. Ground frost-free periods are prolonged, and a negative trend in the duration and thickness of snow cover is recorded in most parts of the country. Although extreme phenomena occurring in Poland are permanently inscribed in its climatic conditions, the threat of strong winds has been increasing in recent years, and the intense precipitation that often accompanies them is the cause of peak discharges and flooding. Forecasts for progressive climate change are not optimistic, either on a global scale or for the country in question. The article examines the impact of climate change on the design, construction and maintenance of engineering structures globally and for Poland. Changes in design standards, selected examples of disasters and solutions to adapt and build resilience to climate change have been analysed. For most building disasters, climatic factors were the direct cause of the disaster, although in the course of the analysis it has usually turned out that the disasters exposed human errors in the design, construction and, to a lesser extent, the improper maintenance of engineering structures. However, there is an increasing number of new approaches to creating a climate change resilient built environment, including the latest one, which proposes to use the grey infrastructure of cities to build resilience to climate change.

Land units refer to coherent spatial areas characterized by a degree of homogeneity concerning certain properties like geology, soils, and climate. The Land use mosaic corresponds to a circumstantial layer representing the landscape’s present state, depicting the present resource allocation factors. Nevertheless, the stable potential layer is related to the stable characteristics of each site and allows the identification of use constraints or potentials. In this study, we use a methodology based on the land unit concept to define a stable potential layer at a regional level. Therefore, land units were delimited for the Central region of Portugal, resulting from the combination of geomorphology, soil parent material, and bioclimatic influence. For each land unit representative sample areas were characterized in terms of their land use mosaic characteristics. For that purpose, selected landscape metrics were used to quantify the land use mosaic geometrical attributes: Shannon’s Diversity Index, Edge Density, Mean Patch Size, and Number of Patches. The existing land use types were also quantified. Finally, a cluster analysis was performed to define groups of samples representing the land units with similar land-use mosaic types. The landscape metrics that best explain the influence of the permanent structure of the territory on the circumstantial structure of use are Shannon's Diversity Index, Edge Density, and Number of Patches. The highest diversity land cover patterns are located in formations with a lithology rich to very rich in silica under Mesomediterranean dry to subhumid climate. The validation of the previously defined land units confirmed the reliability of the proposed methodology, with most of the land units strongly influencing the land use mosaic. The delimitation and characterization of homogeneous land units are useful for the definition of soil suitability and for the choice of the most appropriate uses and activities by the stakeholders.

Wastewater generated during the production of pomace olive oil is complex and highly variable due to different cultivation and processing characteristics. It has a high toxic organic load, low pH, and high chemical and biological demands. To reduce the concentration of chemical oxygen demand (COD) and total phenolic compounds (TPh) in pomace olive oil wastewater, several treatment processes have been studied. These include: (i) coagulation/flocculation, (ii) electrocoagulation, (iii) peroxy-electrocoagulation, (iv) electrochemical peroxidation, (v) Fenton, (vi) electro-Fenton, (vii) photo-Fenton, and (viii) adsorption. Coagulation/flocculation and electrocoagulation resulted in a maximum COD removal of 16%, while techniques involving the addition of hydrogen peroxide (iii-vii) had an average of 78% TPh removal but only 20% COD removal. Adsorption resulted in a maximum of 29% COD and 75% TPh removal. None of the tested techniques were able to remove more than 50% of COD, indicating the difficulty of removing organic matter in this effluent. However, advanced oxidation techniques were effective in degrading phenolic compounds, although they required relatively high dosages of oxidant.

Se analizó la alocución de un colectivo estudiantil, representado por 77 estudiantes distribuidos en 11 grupos de discusión; para ello, se elaboró un abanico de instrumentos propios, que fungen como serie de filtros para reconocer momentos, actores e ideas clave que incidieron en sus posibilidades de sostenerse en la trayectoria escolar. La peculiaridad del discurso es que funge como sujeto colectivo de investigación y no por cada persona que en su momento lo expresó. Así, se procedió a tamizar la diversidad de contenedores del discurso por medio de rejas y tablas analíticas. Se presenta aquí únicamente los arquetipos que resultan de la imagen simbólica que el estudiantado elabora en torno a las formas de docencia que le significan para afianzar su paso por la institución educativa. Los resultados corroboran una interesante complejidad en los arquetipos de docencia resultantes, los cuales, al ser entidades meramente teóricas, extraídas por medio de la mitificación hermenéutica, basada, por citar algunos, en Jung, Durand, Jodelet, Cassirer, Castoriadis, De Rosa, y se conforma un esquema teórico-conceptual a favor de la construcción de condiciones que favorecen la permanencia escolar de las juventudes de la entidad estudiada.

Esta investigación tuvo por objetivo valorar la utilización de un Instrumento para la evaluación de Entornos Virtuales de Aprendizaje (EVA), específicamente el DELES (Distance Education Learning Environments Survey) para el Proyecto Europeo de Educación Inclusiva denominado LOVEDISTANCE (Learning Optimization and Academic Inclusion Via Equitative Distance Teaching and Learning). El supuesto inicial es que el instrumento puede ser útil, pero está desactualizado y no necesariamente enfocado a los objetivos del proyecto LOVEDISTANCE, en particular al de Educación Inclusiva. El ejercicio académico se llevó a cabo en la Universidad de Levinsky, en Tel Aviv, Israel, y el análisis de la información se hizo con un enfoque cuanti-cualitativo, donde se utilizó, en una primera parte, la medida del consenso entre expertos para medir la fiabilidad estadística de las respuestas de los expertos, y después se realizó un análisis de la varianza (ANOVA) para determinar si existían diferencias significativas entre las medias de los grupos; posteriormente, se hizo un análisis cualitativo pormenorizado de las observaciones a partir de tres ejes de análisis: consideraciones del ejercicio investigativo, perfil de los investigadores y análisis de cada escala del instrumento. Algunas de las conclusiones más relevantes fueron que el instrumento es, en su mayoría, útil para los propósitos del proyecto LOVEDISTANCE, pero precisa mejoras en lo referido a las siguientes escalas: relevancia del aprendizaje para el alumno, apoyo por parte del instructor y la medición en la autonomía del estudiante.

Este artigo tem por objetivo analisar as competências e percepções dos professores sobre a carreira de Administração, avaliando até que ponto a docência nesta área contribui para o desenvolvimento profissional dos licenciados em um mercado de trabalho cada vez mais exigente e competitivo. A formação por competências dos cidadãos baseia-se no cultivo de conhecimentos. Sob esse ponto de vista, o trabalho aborda as competências pedagógicas dos professores do Ensino superior do Curso de administração, procurando identificar as competências em geral, apontando sua importância na prática docente face às exigências da sociedade do conhecimento. A parte metodológica consiste em uma revisão da literatura, qualitativa e descritiva. Os resultados sugerem o desenvolvimento de competência docente no campo da formação do professor de administração, uma vez que influencia diretamente na melhoria do desempenho acadêmico no processo educativo, o que contribui para a formação de profissionais de excelência, capazes de responder de forma eficaz, eficiente e específica às necessidades dos alunos. A formação de profissionais competentes, vincula o seu projeto de vida à sua autorrealização e à melhoria permanente do ser humano, para isso é implementada uma abordagem educativa baseada em competências. A qualidade dos professores universitários dependerá de novas formas de ensino e condições de aprendizagem, de novas abordagens de avaliação, da renovação do currículo definido em termos de competências e da formação dos professores para adquirirem as qualidades docentes necessárias. Todo professor deve adaptar-se continuamente a tais mudanças, deve estar atento à qualidade de sua competência docente.

O estudo tem por objetivo analisar como as ferramentas tecnológicas podem melhorar o desenvolvimento cognitivo e emocional de crianças. A introdução dos jogos por meio das tecnologias de informação e comunicação (TIC) no ensino e aprendizagem tem sido tema de debate e discussão nos últimos anos. A perspectiva dessa junção, lúdico e tecnologias, é de vital importância na investigação, pois permite analisar os efeitos que estas podem ter nas crianças e no seu desenvolvimento cognitivo, social e emocional. Além disso, também ajuda a compreender como as TIC e os jogos podem influenciar as práticas pedagógicas e a forma como os professores ensinam as crianças. É essencial considerar que as TIC juntamente com os jogos são ferramentas que podem melhorar a aprendizagem das crianças, se forem utilizadas de forma adequada. O resultado do estudo apontou que, desde muito cedo a conveniência e a necessidade de dominar e introduzir as TIC juntamente com o lúdico na prática pedagógica visando o desenvolvimento cognitivo, contribui positivamente para desenvolver diversas dimensões cognitivas, ativando a memória, estimulando a atenção e a concentração, promovendo a criatividade e a imaginação, e proporcionando oportunidades para o desenvolvimento de habilidades cognitivas superiores, pois existe a necessidade de abordar essas questões para garantir que os alunos possam aproveitar ao máximo o jogo por meio das TIC para o seu desenvolvimento cognitivo.

Published: June 2024

De acordo com dados da Organização Mundial da Saúde, a Síndrome de Burnout constitui- se como uma das doenças com maior prevalência, em conjunto com as doenças cardiovasculares e diabetes. Compreende-se que a Síndrome de Burnout é capaz de acarretar prejuízos à saúde do trabalhador baseando-se nos riscos em que os funcionários estão expostos, especialmente profissionais que atuam na área da saúde. O presente estudo tem como objetivo analisar as evidências científicas acerca da Síndrome de Burnout em profissionais de enfermagem que trabalham nos serviços de urgência e emergência. Trata-se de uma Revisão Integrativa da Literatura que foi realizada nas bases de dados: MEDLINE, LILACS, BDENF e IBECS por meio da BVS, e para melhor seleção dos arquivos também foi utilizado o banco de periódicos SCIELO. Para realizar a busca, foram utilizadas combinações com os seguintes Descritores em Ciências da Saúde (DeCS) “Esgotamento profissional”, “Enfermagem” e “Emergência” combinados por meio do operador booleano “AND” entre si. Foram identificadas 305 publicações, sendo 10 incluídas para análise, considerando-se os critérios de inclusão e exclusão. Entre os resultados, destacam-se que a Síndrome de Burnout mostrou-se mais elevada entre os profissionais de enfermagem, mostrando valores mais acentuados nos que trabalham nos serviços de atendimento móvel de urgência, além dos profissionais com idade mais avançada e baixa renda. Destaca-se a necessidade da implementação de estratégias de promoção da saúde com possam contribuir para a redução do estresse físico, psíquico e emocional que colocam em risco a saúde dos profissionais de enfermagem.
