Windows 11 is one of the products launched by Microsoft. When this research was made, Windows 11 only had 15.54% of global users. Even though the number of users is still much less than Windows 10, which reached 70.3%, in the future the adoption rate of Windows 11 will continue to increase. However, behind the continued increase in adoption, there are problems experienced by users that make users feel uncomfortable when using it, such as the operating system running slowly and applications not running properly. This problem can affect the user experience. This research aims to determine the level of user experience experienced by users using the User Experience Questionnaire (UEQ) method. This research obtained a total of 117 respondents who were shared via social media. Based on the results obtained from respondents, the Windows 11 operating system received a positive evaluation value which, if sorted from the highest, was in the Attractiveness aspect of 1.21, Clarity of 1.12, Stimulation of 1.01, Efficiency of 0.95, and Accuracy of 0.89. Apart from that, there is the Novelty aspect which gets a neutral evaluation value of 0.49. Recommendations that can be made to improve the Windows 11 user experience are to make improvements to the novelty aspect, such as adding new features that did not exist before, as well as changing the appearance to be more attractive.
Finacial Aspects of Municipal Waste Management
Authors: Valach Maroš , Cifranič Michal 
Published: June 2024

Abstract
Municipal waste management plays a crucial role in our communities and has far-reaching implications. Effective waste management contributes to environmental conservation. By reducing waste, recycling, and implementing sustainable practices, we protect our ecosystems and natural resources. Due to the increasing volume of waste and the increasingly complex administration of its collection and disposal, solid waste management is quickly becoming a demanding issue for municipalities all over the world. The objective of the paper was to describe the impacts of communal waste management on municipal budgets and to compare waste management expenditure intensity. The legislative changes, the focus on minimising waste for disposal and promoting a material recycling orientation will have a significant impact on municipal budgets. Local authorities must adjust to the standards established by the European Union. The Slovak Republic will need to progressively adopt these standards by incorporating them into national law

Abstract

Background
Lung cancer is one of the leading causes of cancer-related mortality worldwide. It frequently metastasizes to bone, brain, lung, and liver, causing a shorter survival. Unusual metastasis also occurs. A few reports have been published, and the majority of described metastatic sites involved the gastrointestinal system and, occasionally, the thyroid gland. Gastrointestinal metastasis from primary lung cancer is rare; however, metastasis to the gastrointestinal tract as an event is frequent. However, distant metastasis to the thyroid gland is a rare event for all types of tumors.

Case presentation
In the present study, we report two cases of primary lung carcinoma with isolated colonic and thyroid metastases. The first one was a patient with lung cancer who presented with an acute abdomen and underwent right hemicolectomy, which revealed moderately differentiated adenocarcinoma of lung origin. The second one was a patient who presented with thyroid swelling that was preoperatively diagnosed as a metastatic thyroid carcinoma to the lung. So, the patient underwent total thyroidectomy with bilateral neck dissection. But the microscopic examination showed a picture of metastatic adenocarcinoma with mucoid activity, which was of pulmonary origin.

Conclusion
Thyroid and gastrointestinal metastases from lung cancer are rare, but they should be put into consideration. Clinical and radiologic evaluations are mandatory to help reach the diagnosis, but pathologic confirmation is inevitable.

Published: June 2024

Abstract
Soccer academies are responsible for the comprehensive development of young athletes, including formal education, living, and preparation for tournaments. Research on soccer youth development from the perspectives of coaches and parents of sports academy students has been limited. This study aimed to discover their perspectives on the key internal and external factors that influence the development of young soccer talents. Questionnaire data were collected from 79 coaches and 326 parents of U15 to U19 soccer players across eight soccer academies across four Central and Eastern European countries. The questionnaires presented 33 Likert-scale type questions organized around four dimensions to include internal factors, professional/sports factors, family/school factors, and other external factors.
Independent sample t-tests were used to demonstrate the differences between sub-samples, and a stepwise discriminant analysis to highlight the major influential factors.
The results indicate that both coaches and parents emphasize the importance of internal, professional/sports, and other external factors in soccer talent development. Coaches ranked cognitive (t=2.450, p=0.015), psychological (t=3.082, p=0.002), pedagogical (t=2.663, p=0.008) and moral role modeling (t=3.382, p=0.001) factors higher than parents. Parents gave higher priorities to the importance of the team’s results in the championship (t=-4.827, p=0.000), school results (t=-4.028, p=0.000), and financial support from family (t=-6.836, p=0.000). Overall, coaches’ beliefs focus upon professional conduct, expectations of the profession and the academy, while parents focus on supporting their children’s school and sports successes.
Ongoing cooperation between parents and coaches is critical to bring positive changes in the development and long-term successes of young players.
The violent beauty of a banlieue wasteland garden
Authors: Harper Sarah 
Published: June 2024

Abstract
Participatory arts can invite stormy and violent forms of participation when they are commissioned for sites where frustration, territorial control and pre-emptive self-defense involve practices of accepted street codes by those living within racialized, febrile territories. Through the case study of Aroma Home, a participatory art gardening project, in Paris’s northern peripheries, I analyze instances of affective, symbolic, performative and territorial violence as non-normative political acts of participation. Examining the underlying contexts and logics that led to these incidents, I argue that the most insidious act of violence in the project was the creation of our invasive, extractive garden on a hitherto unclaimed and unidentified patch of ‘free’ public ground. In creating a new identity for this wasteland and defining its use, we effectively limited, and implicitly prescribed, modes of participation that were culturally alien to those we most wanted to involve.
Deconstructing homelessness: Alternative narratives on and by marginalized and homeless groups in the city of Bologna
Authors: Sabatini Francesca 
Published: June 2024

Abstract
The paper addresses the political and cultural problem underpinning mainstream narratives on homelessness. The absence of data, in conjunction with the misconceptions associated with homelessness, translate into the criminalization and stigmatization of homelessness, both at the local level and in fragmented policies at national and international levels. Section one presents an overview of homelessness as a cultural and political problem; section two then introduces the Italian situation and Bologna as a case study. After a presentation of the method followed in section three, sections four and five describe and then discuss two projects initiated by a political collective in the city of Bologna that directly involve homeless people in the deconstruction of imageries and narratives around homelessness. Finally, section six draws conclusions about the need to generate new narratives capable of accounting for the intersectional and complex nature of the phenomenon of homelessness: new narratives capable of restoring to the homeless their articulate human identity.

Objective: It aims to carry out a comprehensive review of the scientific literature on this serious complication. Through critical analysis of relevant articles, we seek to deepen knowledge about the main infection control measures, the clinical panorama of events and the impacts on patients' health.

Method: In a systematic journey through relevant databases, such as PubMed, LILACS and SCIELO, 10 studies published between 2019 and 2024 were identified and analyzed.

Results and Discussion: The incidence of ACSC varies according to several factors, such as type of catheter, insertion site, length of stay and patient characteristics. The use of long-term catheters, insertion into the subclavian vein and colonization by antibiotic-resistant microorganisms increase the risk. ACSI can manifest itself through fever, chills, sweating, hypotension and other symptoms. Diagnosis is made through blood cultures and other laboratory tests. ACSCs can lead to prolonged hospitalization, increased costs, septic shock, organ failure and death. Preventing CLABSIs is fundamental and depends on rigorous measures, such as: Recent literature offers several valuable studies that contribute to the understanding of CLABSIs. The development of risk prediction models and the implementation of prevention packages such as the PPC are promising tools for reducing the incidence of CLABSI and improving patient outcomes.

Conclusion: CLABSI represents a significant challenge, but with effective prevention and control, we can minimize its impacts and guarantee patient safety. Continuous research and implementation of best practices are essential to combat this serious complication.
Enzymatic precipitation of cadmium by means of native bacteria of the genus Citrobacter.
Authors: Mogollón L. I. , Rodríguez M. R. , Ramírez N. E. , Zaucher F. 
Published: June 2024

Native strains were isolated from heavy metal contaminated waters and soils. The microorganism selection was conducted based on the quantification of the phosphatase enzyme activity. Citrobacter cells in batch studies showed five times more enzymatic activity than that of available collection cultures and the reported values in previous studies using other strains. Uptake results show that cadmium removal increases with cell exposure time when the cell are in the presence of the enzymes substrate glycerol 2-phosphate. Metal enzyme affinity improves by increasing solution pH to 8-1 0. Precipitation is caused by passive bounding of cadmium to reactive groups at the cell wall and the "in situ" metal accumulation as nonsoluble phosphate on microbial cells wall.

The return home: Disability experiences of Second World War Veterans with amputations
Authors: Lowe Mikaela , Lara Peralta Fernanda , Letts Lori 
Published: June 2024

LAY SUMMARY Analysis of oral history interviews conducted with Canadian Second World War Veterans with amputation identified themes of disability experiences. Overall, the experience and understanding of disability by Veterans with amputation was based on activities they could perform independently, how others saw them, and how they viewed their injuries. The inherent pride and masculinity in not showing a disability was celebrated by the Veterans and is still relevant today, where life-changing injuries, such as amputations, are often thought of as tragedies an individual needs to be strong enough to overcome. The way disability was understood during this time as an individual responsibility influenced today’s military culture. Rehabilitation professionals working with military personnel are encouraged to be conscious of reinforcing injuries as tragedies that need to be independently overcome.
ANÁLISE PSICANALÍTICA DA SEXUALIDADE EM SUJEITOS COM DEFICIÊNCIA INTELECTUAL
Authors: Souza Débora Viana de 
Published: June 2024

O presente artigo orientado pela psicanálise, procurou estudar a condição sujeitos com deficiência intelectual no desejo materno e os efeitos dessa interação na constituição de sua sexualidade. Ao nascer, a forma como a criança é acolhida pela mãe e inserida no meio familiar é determinante na constituição do sujeito, pois é a partir dessa relação pulsional que se pode ter condições de ser inserido no campo da linguagem, permitindo ao sujeito a sua inserção ao mundo comum. Dessa forma, a pesquisa visou analisar quais os efeitos e consequências quando a criança, pelo fato de sua deficiência, é imersa no campo do Outro materno, tornando- se um corpo de puro objeto, em que o seu saber só pode ser localizado no campo do Outro, seja no campo da medicina, bem como no campo materno. Para tanto, foi realizada uma pesquisa bibliográfica sobre conceitos psicanalíticos, retomando alguns autores, como Jacques Lacan e Maud Mannoni, que permitem verificar a posição subjetiva desse sujeito através da fórmula Holofráse em relação ao Outro e o modo como esses sujeitos conseguem lidar com sua própria sexualidade. Assim, esse artigo procurou salientar pontos importantes na construção de um saber do campo sexual e a particularidade de sujeitos com deficiência intelectual nesse processo, pois a maneira como o sujeito é acolhido pela mãe é o que determina sua posição frente ao seu próprio desejo, limitando ou possibilitando sua condição de se relacionar como sujeito do desejo e, dessa forma, ter condições necessárias de vivenciar momentos de prazer com o Outro.
