Environmental issues have been a prominent issue worldwide and the increase in plastic production and the lack of post-consumer waste management programs result in inadequate disposal and deposition in terrestrial and aquatic environments, causing environmental impacts. This paper was developed through the analysis of aspects of pedagogical practice in relation to environmental education with the plastic theme and its environmental impact on the environment. In this perspective, environmental education through the individual and the collectivity builds social values, knowledge, skills and competences aimed at the conservation of the environment. However, it was observed that addressing environmental issues should be considered a challenge for teachers, as it is a broad and diverse subject, as they are not prepared for the development of these activities and schools do not have the infrastructure to meet the needs of approaches to environmental issues.

La educación ambiental es fundamental en la vida del ser humano, permite desarrollar hábitos que conllevan al desarrollo sostenible de la sociedad y la toma de conciencia sobre el medio natural del cual dependemos para la existencia de la vida como la conocemos. Los reglamentos que se establezcan en un país no son los que van a mejorar los conocimientos y actitudes ambientales; sino la educación constante de cada miembro de la sociedad; porque son las acciones individuales que sumadas en forma colectiva tienen el efecto de cambiar los hábitos y cultura de una comunidad. Ante esta situación, los docentes de las instituciones educativas deben ser pioneros en los temas medioambientales. Aún existe falta de consciencia ambiental, a causa de aquello ya se ha llegado a hechos irreversibles en el medio como perdida de áreas verdes y extinción de especies, entre otras consecuencias que seguirán sumándose si no actuamos ahora. Esta investigación se realizó en las instalaciones de la Universidad Técnica Estatal de Quevedo, con el propósito de valorar la incidencia que la educación ambiental tiene sobre sus alumnos y la práctica de valores que este tema deriva. Los métodos utilizados en la investigación son analítico, descriptivo y deductivo; los resultados encontrados revelan que al menos la mitad de los estudiantes, ocasionalmente aplican valores de educación ambiental en sus días cotidianos para el cuidado del medio ambiente; mientras que la mayoría de los estudiantes está de acuerdo en que la poca práctica en educación ambiental conlleva a la contaminación de los ecosistemas. PALABRAS CLAVE: medioambiente; educación ambiental; valores medioambientales; sostenibilidad; sustentabilidad. ENVIRONMENTAL EDUCATION AND PRACTICE OF VALUES OF UNIVERSITY STUDENTS ABSTRACTEnvironmental education is fundamental in the life of the human being, allows developing habits that lead to the sustainable development of society and awareness of the natural environment on which we depend for the existence of life as we know it. The regulations that are established in a country are not those that will improve environmental knowledge and attitudes; but the constant education of each member of society; because they are the individual actions that added together collectively have the effect of changing the habits and culture of a community. Faced with this situation, teachers of educational institutions must be pioneers in environmental issues. There is still a lack of environmental awareness, because of that irreversible events have already occurred in the environment such as the loss of green areas and the extinction of species, among other consequences that will continue to be added if we do not act now. This research was carried out in the facilities of the State Technical University of Quevedo, with the purpose of assessing the impact that environmental education has on its students and the practice of values ​​derived from this topic. The methods used in the research are analytical, descriptive and deductive; the results show that at least half of the students occasionally apply values ​​of environmental education in their daily days for the care of the environment; while the majority of students agree that the little practice in environmental education leads to the contamination of ecosystems. KEYWORDS: environment; environmental education; environmental values; sustainability; sustainability.

Abstract Introduction Audit of waste management in an elective orthopaedic complex was interrupted due Covid-19 pandemic. We investigated the impact of the enforced changes on theatre waste due to Covid-19. Method Over a 1week period data on waste bag availability and number of bags of each category of waste per surgical case in an elective theatre complex was collated; this was compared to waste generated during Covid-19 pandemic. Results Prior to Covid-19 only clinical waste bins were available in many non-dominant clinical areas providing evidence of inappropriate routine disposal of domestic/recyclable waste. Pre-Covid-19 a mean of 6waste bags were used per surgical case (3.7yellow clinical bags, 1.3black domestic bags, 0.4clear recycling bags), with Covid-19 changes to waste management practice the mean number of waste bags used per case increased to 11 (9 orange contaminated bags, 0.5black, 0.3clear bags). Conclusions Clinical waste management has a significant economic and environmental impact. Covid-19 has led to nearly all waste being deemed to be contaminated and so requiring incineration, with increased volumes of waste generated per case through widespread adoption of PPE. This has increased cost and reduced the ability to recycle non-contaminated waste.

The nuclear industry uses computer models to calculate and assess the impact of its present and future releases to the environment, both from operating reactors and from existing licensed and planned waste management facilities. We review four soil models varying in complexity that could be useful for environmental impact assessment. The goal of this comparison is to direct the combined use of these models in order to preserve simplicity, yet increase the rigor of Canadian environmental assessment calculations involving soil transport pathways. The four models chosen are: the Soil Chemical Exchange and Migration of Radionuclides (SCEMR1) model; the Baes and Sharp/Preclosure PREAC soil model, both used in Canada's nuclear fuel waste management program; the Convection-Dispersion Equation (CDE) model, commonly used in contaminant transport applications; and the Canadian Standards Association (CSA) derived release limit model used for normal operations at nuclear facilities. We discuss how each model operates, its timestep and depth increment options and the limitations of each of the models. Major model assumptions are discussed and the performance of these models is compared quantitatively for a scenario involving surface deposition or irrigation. A sensitivity analysis of the CDE model illustrates the influence of the important model parameters: the amount of infiltrating water, V; the hydrodynamic dispersion coefficient, D; and the soil retention or partition coefficient, Kd. The important parameters in the other models are also identified. This work shows we need tested, robust, mechanistic unsaturated soil models with easily understood and measurable inputs, including data for the sensitive or important model parameters for Canada's priority contaminants. Soil scientists need to assist industry and its regulators by recommending a selection of models and supporting them with the provision of validation data to ensure high-quality environmental risk assessments are carried out in Canada. Key words: Soil transport models, environmental impact assessments, model structure, complexity and performance, radionuclides 137Cs, 90Sr, 129I

El presente trabajo se realizó con el objetivo de indagar acerca de los conocimientos sobre temas ambientales generales, los hábitos cotidianos, la predisposición hacia el cuidado del ambiente y el índice de cultura ambiental de un grupo de estudiantes ingresantes a la carrera ingeniería agronómica de la Universidad Nacional de Luján (UNLu) y consistió en una encuesta escrita, individual y anónima realizada a 81 alumnos. Los resultados obtenidos permiten afirmar que resulta necesario promover no solo la difusión de conocimientos vinculados al impacto de las actividades de producción agropecuaria sobre el ambiente natural, sino también la separación de residuos, la reutilización de materiales tales como papel, vidrios o metales, la compra de productos que sean amigables con el ambiente, la disminución del consumo de productos innecesarios, la utilización de bolsas reutilizables al hacer las compras y los desplazamientos a pie o en bicicleta y con el fin de lograr que estos hábitos puedan extenderse a un mayor número de personas. Estos resultados, sumados al interés expresado por los encuestados en participar en diferentes acciones vinculadas al cuidado del ambiente natural, invitan a pensar en la importancia de desarrollar acciones de educación ambiental desde las distintas instituciones educativas, incluida la universidad. Abstract The present work was carried out with the aim of inquiring about knowledge on general environmental issues, daily habits, predisposition towards caring for the environment and the index of environmental culture of a group of students entering the agronomic engineering career at the National University of Luján (UNLu) and consisted a written, individual and anonymous survey of 81 students. The results obtained confirm that it is necessary to promote not only the dissemination of knowledge related to the impact of agricultural production activities on the natural environment, but also the separation of waste, the reuse of materials such as paper, glass or metals, the purchase of products that are friendly to the environment, the decrease in the consumption of unnecessary products, the use of reusable bags when shopping and traveling on foot or by bicycle and in order to ensure that these habits can be extended to a greater number of people. These results, added to the interest expressed by the respondents in participating in different actions related to the care of the natural environment, invite us to think about the importance of developing environmental education actions from the different educational institutions, including the university.

In this democratic era, two of the largest previously disadvantaged communities in Port St Johns i.e. Mtumbane and Maheng were still without waste collection services. Solid waste was dumped indiscriminately and posed risks to health and the environment. To help these communities to achieve better health, this study aimed to investigate the effectiveness of environmental education on waste management practices (WMP). The key objectives entailed establishing the knowledge, attitude and behaviour of sampled households towards WMP; evaluating the intervention of the 4Rs (reuse, reduce, recycle and recover) of WMP as taught to Grades 4 to 7 residing in the previously sampled households and assessing the impact of the intervention on WMP in these households. This study was undertaken in three phases. The pre-intervention and post-intervention phases included questionnaire administration occurring over two months. The intervention comprised the teaching of the 4Rs of WMP and the completion of a daily diary by Grades 4 to 7 residing in the previously sampled households.This study focused on statistically significant differences that were reported between pre- and post- intervention. The differences were meant to establish if the respondents had any changes in knowledge regarding solid waste management. Results showed that the use of plastic bags increased which showed a significant difference (p-value 0.034).Indiscriminate dumping of waste in Mtumbane decreased whereas in Maheng, there was no difference with their practices. Among the majority of respondents from Mtumbane, waste was regarded as something useful (p-value 0.003). The education associated with waste management for both townships increased by more than 15% and that made a significant difference (p-value 0.025). Further, more than half of the respondents in Mtumbane separated their waste. The results show that there was a significant difference (p-value 0.001) in Mtumbane and not in Maheng. This significant difference may be attributed to the distribution of adequate information as the two townships vary in distance from the municipal offices i.e. Mtumbane: three kilometres and Maheng: 15 km). It was found that the number of respondents willing to pay for waste collection services increased post-intervention (p-value 0.003). It appears that in every aspect when pre- and post-intervention were reported, there was a positive difference after the intervention phase. Four recommendations are proposed: (1) organising solid waste cleaning campaigns and environmental education in schools and communities; (2) the introduction of the 4Rs to communities; (3) the provision of communal waste skips and (4) the use of incentives to foster proper waste disposal practices. It is important for all future studies to consider a method for disseminating important information to the community in order that waste management strategies can be fully and successfully implemented.

The Christian Foundation for Children and Aging (CFCA) is an organization that responds to environmental awareness and education through an environmental recollection. Environmental recollection was conducted among twenty student respondents who are scholars of CFCA. Using a researcher-developed questionnaire, data on the level of knowledge on four environmental issues: global warming, climate change, waste management and resource preservation and the action plans were gathered. Results show that the student respondents are well informed of the environmental issues prior to the environmental recollection but a significant increase in the level of knowledge was found after the environmental recollection. The students strongly agree on the plan to preserve the resources and the proper waste management procedures. All the students get information on environmental issues from their teachers, while majority also obtain them from media and seminars. Other information was obtained from home through their parents, classmates, and pamphlets. There is significant association between prior level of knowledge in waste management, prior level of knowledge in resource preservation and the post level of knowledge in all environmental issues and number of sources from which they get the information. Environmental recollection is a good tool in awakening the students in the current environmental situation.   Keywords - environmental recollection, environmental education, environmental sensitivity, environmental awareness, responsible behaviour, preservation

AbstractEnvironmental issues, linked to the production of animals in lowland farming systems, are reviewed, using pigs, poultry and dairy cattle as examples. The principal livestock production factors influencing their environmental impact are identified as the balance between different farm animal types and the husbandry practices used for these species, the variable potential which exists for the recycling of wastes and the modification of inputs to systems, the extent to which animal production can be integrated into more holistic farming systems and the impact of livestock on 'wildlife' (plant and animal) biodiversity. The production of large quantities of nitrogenous waste, resulting from the importation of large quantities of nitrogen to intensive animal production units, is identified as the major environmental problem for lowland animal production. The development of-systems which allow these waste products to be re-used at sites of primary crop production is seen as a sustainable solution to this problem.

We aimed to determine the relationship between gaming disorder, narcissism, and happiness levels of children between the ages of 9 and 15. This study was based on the compensation theory. The sample consists of 461 boys who continue their education in public schools in Istanbul. In the study, a mixed research design, which nests qualitative data into quantitative, was used. In addition to the scales and sociodemographic form, the Draw-a-Person test was also used to better understand children’s inner world. According to the findings, there is a significant relationship between gaming disorder and narcissism and happiness levels in children. Accordingly, as narcissism increases in children, the gaming disorder level increases, and happiness decreases. We also found a mediation effect in the impact of narcissism on happiness through gaming disorder. According to the results, we think that the problem is not caused by the individual but by society. For a solution, we recommend making more macro-level social work interventions within the framework of system theory instead of the current medical model in combating gaming disorder.

AbstractThe goal of this article is to analyse the impact of specific public policies on the school trajectories of socially vulnerable Ciganos (Gypsies/Roma) who reside/live in the Metropolitan Areas of Lisbon and Porto. Through carrying out qualitative research, the analysis of key factors will allow us to understand the reasons behind school continuity and educational success of Ciganos, as well as the identity (re)configuration processes associated with the education paths of these individuals. We find that trajectories are not only intertwined with public policies and programmes, but also with other explanatory factors inherent to the individual, to the type of support he/she receives from his/her family, the presence of key figures in their lives, and the importance of peers and institutional factors inherent to the way public schools operate.

Compreendamos a Educação Ambiental como sendo um bloco de ensinamentos teórico-práticos que objetiva fazer com que o indivíduo atente para as ações promovidas por ele mesmo e perceba a importância destas para a preservação e conservação do meio ambiente, visando o bem-estar e a saúde de todos os seres vivos. O objetivo desta pesquisa foi fazer um levantamento do perfil dos gestores escolares entrevistados, além de analisar as contribuições dos gestores para a promoção do conhecimento acerca dos temas “Sustentabilidade” e “Meio Ambiente”, contribuindo para a Educação Ambiental nas escolas e na sociedade. Esta é uma pesquisa de campo e apresentou uma abordagem qualitativa, sendo realizada em sete escolas de ensino público municipal da Regional V, na cidade de Fortaleza. Participaram desta pesquisa sete gestores escolares, das sete escolas que foram o cenário desta pesquisa. Utilizou-se um questionário e uma entrevista semi-estruturada para a coleta de dados. Sobre o exercício da função de gestor, percebeu-se que 71,4% dos entrevistados gerem apenas uma escola, enquanto apenas 28,56% gerem duas ou mais. Notou-se, também, que, sobre o tempo total de experiência na função, 28,56% dos entrevistados informaram que têm entre 16 – 20 anos como gestor e, sobre o tempo de gestão nas escolas atuais, 42,84% estão entre três e cinco anos na função. Conclui-se que, na comunidade escolar, todos os integrantes têm o seu devido papel, mas, diante da sua função, o gestor é a pessoa responsável por incentivar, apoiar e se mostrar disponível para ações desta natureza.AbstractWe understand Environmental Education as being a block of theoretical-practical teachings that aims to make the individual attentive to the actions promoted by himself and realize the importance of these for the preservation and conservation of the environment, aiming at the well-being and health of all living things. The objective of this research was to survey the profile of school managers interviewed, as well as to analyze the contributions of managers to the promotion of knowledge about "Sustainability" and "Environment", contributing to Environmental Education in schools and society. This is a field research and presented a qualitative approach, being carried out in seven municipal public schools of the Regional V, in the city of Fortaleza. Seven school managers participated in this research, from the seven schools that were the scene of this research. A questionnaire and a semi-structured interview were used to collect data. Regarding the role of manager, 71.4% of respondents managed only one school, while only 28.56% managed two or more. It was also noted that 28.56% of the respondents reported that they had between 16 and 20 years of age as manager, and 42.84% of their three and five years in office. It is concluded that, in the school community, all the members have their proper role, but, given their role, the manager is the person responsible for encouraging, supporting and showing himself available for actions of this nature.
