Abstract This paper presents a comprehensive approach to the sizing of parallel hybrid propulsion systems for multi-megawatt aircraft, with a specific focus on baseline turboprop aircraft. By exploring key performance variables such as power distribution, system efficiency, or fuels and aircraft weights. The study provides a detailed analysis of how these factors influence overall hybrid aircraft performance. Special attention is given to the impact of these variables on range and fuel consumption, aiming to quantify potential fuel savings and range improvements under different operating conditions. The paper investigates the level of hybridization at various phases of flight, such as take-off, climb, cruise, and descent, seeking to optimize the distribution of power between the electric power train (fuel cell sizing) and gas turbine propulsion systems. By evaluating different scenarios and performance sensitivities, the study aims to identify optimal design strategies for enhancing both efficiency and sustainability in future aircraft propulsion systems. The findings contribute to a better understanding of how hybrid-electric technologies can be integrated into next-generation turboprop aircraft, with implications for reducing emissions and quantify impact on top level aircraft requirement.

This paper aims to analyse the main trends in the intersection of these two fields, the current focus of the literature and synthesises the main findings. Design/methodology/approach The analysis consists of bibliometric literature research and relevant peer-reviewed literature content analysis based on a corpus of 74 papers. The analysis aims to understand how sustainable entrepreneurs can fund their ventures and the main funding sources that could be used. The study also presents the challenges and the strategies to fund sustainable ventures. Findings The findings show that the literature in the field is still nascent, even though scholars have shown a growing interest in it in the past five years. The focus of the literature is quite diverse between macro- and micro-level analysis and there are some rising topics such as alternative finance like crowdfunding. Originality/value Based on the content analysis, the paper synthesises the main trends of the literature and identifies some potential research gaps, such as post-funding empirical research and the efficiency of regulations supporting the emergence of sustainable entrepreneurship.

<i>Goal:</i> This pilot study aims to assess accuracy in detecting patient presence or absence by using a bed sensor based on mmwave radar technology above the patient bed. <i>Methods:</i> Patients and healthy volunteers were observed during their presence or absence in a bed in hospital and home location. These observations were compared with data coming from bed sensor monitoring patient presence using tina.care bed sensor ASWA. <i>Results:</i> A total of 53 different observations were performed during the study period and the bed sensor reached accuracy of 94%, precision of 90%, sensitivity of 99% and specificity of 89% to detect presence or absence of patients in a bed. <i>Conclusions:</i> The sensor demonstrated strong performance in detecting patient presence in bed, with reasonable specificity and low false negatives. Further research should assess bed-exit and bed-entry events, system's accuracy in a larger cohort, its impact on patient care, and the precision of vital health parameters measured by the sensor in order to compare it with similar studies.

Para manter a vantagem competitiva e a satisfação dos seus clientes, as empresas devem analisar constantemente seus processos de atendimento, com o propósito de identificar oportunidades de melhoria. Dentre os pontos a serem investigados, as filas é um dos fatores que geram maior incidência de insatisfação dos clientes, devido aos longos tempos de espera associados à sua formação. Desta forma, o presente trabalho tem por objetivo investigar e analisar como a simulação computacional pode otimizar o fluxo de atendimento, reduzir os tempos de espera e melhorar a qualidade do serviço prestado aos pacientes em uma unidade hospitalar no município de Natal/RN. Para isso, foi utilizada uma metodologia descritiva, aplicada e qualitativa, com o método de estudo de caso e aplicação do software Arena. Primeiramente, foram coletados, durante seis meses, dados sobre o fluxo de atendimento atual na unidade hospitalar, incluindo os tempos de espera, a utilização dos recursos e as demandas dos pacientes. Em seguida, foi desenvolvido um modelo de simulação computacional que reproduzisse o sistema de atendimento atual. Esse modelo foi validado com base nos dados reais coletados. A simulação apontou elevados tempos de filas nas etapas de atendimento e triagem. Diante disso, foram realizadas simulações com diferentes cenários e estratégias para identificar as melhores soluções para otimizar o fluxo de atendimento. Por fim, foi proposto a inserção de profissionais nos setores e apontados como gargalos, o que resultou em melhoria no atendimento e redução significativa no tempo de espera das filas. Assim, com essas medidas, espera-se aumentar a satisfação dos clientes sem incorrer em elevados custos para a organização.

The current study seeks to examine the learning outcomes of an ESP course project intended for MA students of Management and Human Resources. The project´s aim is to create learning opportunities that are perceived as relevant by students in terms of progress in language proficiency, field subject knowledge, developing professional skills, and personal growth. The main priority is to integrate the current Business English course curriculum (C1) with real-life tasks in real-life settings that are considered authentic and relevant enough to increase student engagement and motivation in learning. The presented study examines the affective learning outcomes (students´ perceptions of the project assignment benefits and the experience of doing research), cognitive outcomes (students´ perceptions of the language and subject knowledge growth), and behavioural ones (skills and engagement). The project evaluation results will be used to enhance students´ satisfaction with the ESP course and improve the project assignment and its procedures.

The paper proposes a new soil evaluation system using the principle of the Saaty method. The Saaty method has been modified and named Soil Assessment System (SAS). Significance weights are assigned to individual soil characteristics (indicators). This provides a more detailed differentiation of the significance of the indicator on soil quality and a more accurate assessment, especially in marginal cases where the assessment by the methods used so far has not been fully conclusive. In addition to physico-chemical properties, other criteria are taken into account to assess not only productional but also non-productional functions. The possibility of using indicators referring to a broader context (e.g., soil sealing value) is also important, thus enabling a comprehensive assessment of the quality of the land. This results in points for individual sampling locations. Soils are categorized according to the number of points and results are shown on maps.

Cultural tourism is critical to the growth of destinations all over the world. Cultural activities and events, as well as existing local historical and cultural assets or cultural capital, shopping, and event attractions, are all believed to play a key role in the nations' cultural and economic development. In the Nepalese context, cultural tourism is widely discussed for the potential development of local and indegenous communities. Thus, the research aims to identify Newari Community’s attitude toward promoting cultural tourism development in Kathmandu Valley. Newari community people from Kathmandu valley were taken as a population, a total of 280 individuals were taken as a sample, and data were collected using a structured questionnaire. The attitude level of Newari people was measured using the attitude index. The Ordered Logistic Model was used to test the factors determining the Newari community's attitude towards promoting cultural tourism development. The result revealed that the Newari community is highly aware of cultural tourism development. Further, regression result shows that monthly income, employment opportunities, a wide variety of cultural activities, developed partnership, pride of local residents, sufficient information, cost of living, a problem with parking or traffic, and household employed in art and cultural activities statistically influence attitude level of Newari community to promote cultural tourism development. Hence, the Newari community should focus on promoting cultural tourism development through conservation, protection, and development of cultural management.

People make three general types of judgments to express importance, preference, or likelihood and use them to choose the best among alternatives in the presence of environmental, social, political, and other influences. They base these judgments on knowledge in memory or from analyzing benefits, costs, and risks. From past knowledge, we sometimes can develop standards of excellence and poorness and use them to rate the alternatives one at a time. This is useful in such repetitive situations as student admissions and salary raises that must conform with established norms. Without norms one compares alternatives instead of rating them. Comparisons must fall in an admissible range of consistency. The analytic hierarchy process (AHP) includes both the rating and comparison methods. Rationality requires developing a reliable hierarchic structure or feedback network that includes criteria of various types of influence, stakeholders, and decision alternatives to determine the best choice [8]. for well-known statement that the maximal eigenvalue \(\lambda_{\max }\) is equal to \(n\) for the eigenvector problem \(\mathrm{A} w=\lambda w\) where \(A\) is, so called, the consistent matrix of pairwise comparisons of type \(\mathrm{n} \times \mathrm{n}(\mathrm{n} \geq 2)\) with the solution vector \(w\) that represents the probability components of disjoint events. Moreover, we suggest an algorithm for the determination of the eigenvalue problem solution \(A w=\mathrm{n} w\) as well as the corresponding flowchart. The algorithm for arbitrary consistent matrix \(A\) can be simply programmed and used.

Cílem této práce je zjistit, zda a do jaké míry současné učebnice obecného francouzského jazyka pro dospělé podporují u studentů rozvoj nepřímých strategií učení. Metodou výzkumu byla obsahová analýza, při které jsme detailně prozkoumali 5 sérií současných učebnic francouzského jazyka. Bylo zjištěno, že většina z těchto sérií učebnic nepřímé strategie učení rozvíjí spíše v menší míře. Za nejzdařilejší v tomto ohledu považujeme sérii Nouveau Rond-Point. Autoři této řady učebnic věnují pozornost všem typům nepřímých strategií učení – tj. jak metakognitivní, tak afektivní i socializační.
