Authors: ANTIPENKO A.A.
Published: November 2024

Large integrated production structures are an integral part of the base that ensures the stable development of the economy, which, using the tools of technological development, allow accumulating the potential of industrial enterprises in order to ensure competitiveness in the world market. One of the key branches of Russian industry, in which a significant share belongs to vertically integrated production structures, is metallurgical production. The effective development of metallurgical production is one of the key factors that contribute to the development of related industries and have a positive impact on the growth of the efficiency of the state economy as a whole. Thus, the article reflects the importance of the development of the metallurgical industry for Russia, in which today there are a large number of both internal and external difficulties that need to be overcome. The main purpose of the scientific article is to study the current level of development of the metallurgical industry and the metallurgical industry as a whole, as well as to determine the factors that slow down this process. Based on the analysis carried out in the article, the conclusion is formed that the metallurgical industry is vulnerable and dependent on a combination of internal and external factors. Thus, in order to effectively develop the metallurgical industry in the long term, it is necessary to use methods of state support aimed at overcoming negative factors and supporting the long-term sustainable development of the industry, since the level of development of metallurgy largely depends on the degree of development of related industries. The results of the study may be in demand for understanding issues related to the current level of industrial development and factors affecting it, mainly in the field of metallurgical production.

Published: November 2024

Currently the effectiveness of personnel is the most important factor in the success of the organization. That is why the assessment of factors and reserves for the growth of labor productivity is necessary for every organization. Special attention should be paid to the evaluation of middle managers activities. Until recently, there was an opinion that middle managers as a separate social group did not exist - it was believed that their functionality and social capital did not differ from the functionality and social capital of other managers. It has now been proven that middle managers are a separate group that has its own characteristics and socio-demographic features, and performs functions that are different from other categories of personnel. That is why, when identifying reserves for labor productivity growth, a group of middle managers should be considered separately. The article presents the results of a study of the reserves of labor productivity growth of middle managers in Russia and Belarus. To assess the reserves, there was carried out an analysis of the managers’ labor practices by conducting a workday study by observing them at certain points in time. In total, there was collected information on 17,592 periods, which then were analyzed to find reserves for labor productivity growth. As a result, there were identified some reserves, the use of which will increase labor productivity. We also identified differences in reserves among managers of two countrie. It was concluded that the cross-country differences in reserves are due to national peculiarities of doing business. At the same time, both countries are characterized by the presence of such a reserve as performing work as a specialist. More than a quarter of the working time of the managers studied was spent on performing this function. Working with this reserve will significantly increase labor productivity.

Authors: Shaymaa Majeed AL–Dahlaki
Published: November 2024

Protues mirabilis has the ability to induce urinary tract infections primarily has to do with theformation of biofilms on catheter and UTI surfaces. This bacteria expresses a number ofvirulence factors essential to the creation of biofilms. Fifty urine specimens were taken frompatients who were hospitalized and under treatment from the clinical laboratories of BaqubaTeaching Hospital. Of those fifty specimens, fifteen clinical specimens were positive forisolates of Protues mirabilis. The results showed that all the P. mirabilis isolates under studywere 100% resistant to the Gentamicin, Cefotaxime and the resistance of the isolates toVancomysin and Azithromycin were 90%, Cefixime, Augmentin by 80%, and their resistanceto Piperacillin-tazobactam by 70%. According to these percentages, the isolates were dividedinto two classes Extensively Drug Resistance (XDR) (90%), which were resistant to the sevenantibiotics that were used in the study, and (10%) were Multi Drug Resistance (MDR) whichwere resistant to four antibiotic. Results showed that the P. mirabilis have the ability to producebiofilm, all isolates could produce biofilm but in deferent percentage 70% were strong ,30%were moderate, and the absorbency value was ranged from (0.353 – 0.159). The conventionPCR analysis revealed that the gene (Esp), encoding the enzymes that cause Proteus mirabilisto form biofilm, accounted for 15 (40%) of the total.
A sectoral perspective on corporate cash holdings
Authors: Botha Ilsé , Thompson Carol
Published: November 2024

The main purpose of this research is to investigate the cash holdings behaviour on sectoral level for South African firms listed on the Johannesburg Stock Exchange (JSE). The accounting cash ratio is used to identify abnormal (excess) cash holdings for the firms listed on the JSE. This informed the panel regression analysis to identify cash holdings determinants on a sectoral level. The sample data included 255 firms of which 102 represent Financial Firms and 153 represent Non-Financial Firms for 2005 to 2019. The findings show the significant internal and external determinants of cash holdings. Comparing coefficient sizes, this research finds that financial and non-financial sectors with abnormal (excess) cash holdings exhibit higher coefficient sizes as opposed to sectors without. As a result, the higher coefficient size shows that the internal and external determinants of cash holdings have a greater effect on the cash holding levels of these sectors. The implications of the findings of this study are that each sector operates differently and that each firm within each sector has differing cash management policies and procedures. Therefore, analyzing cash holdings behaviour on an aggregated level and assuming that all sectors and firms within the collective operate the same is an erroneous assumption, as shown by this study. This research firstly contributed by introducing the use of the accounting cash ratio to indicate the presence of abnormal (excess) cash holdings. Most research focus on cash holdings of Non-Financial Firms. Therefore, the second contribution of this research is that both Non-Financial and Financial Firms with and without abnormal (excess) cash holdings were included to identify determinants of cash holdings, this was also done on a sectoral level.

Published: November 2024

Our study aimed to assess the prevalence of fall risk-increasing drugs (FRIDs) in a sample of community-residing older patients in Croatia and its association with negative health outcomes. An observational, cross-sectional study was conducted on older patients (65+) visiting community pharmacies in three regionally different study sites in Croatia. Data were collected using a questionnaire developed for that purpose and included components of comprehensive geriatric assessment. Prevalence of FRIDs was identified using the “Screening Tool of Older Persons Prescriptions in older adults with high fall risk” (STOPPFall). In the sample of 407 participants (median age 73 (IQR 69–70) years; 63.9 % females), 79.1 % used at least one FRID. The most common drug classes were diuretics, benzodiazepines, and opioids (in 51.1 %, 38.1 %, and 17.2 % participants, respectively). More FRIDs were prescribed to the oldest old patients (85+) and participants from poorer regions of Croatia (Slavonia) (p < 0.05). Exposition to FRIDs was identified as the significant risk factor associated with falls (OR = 1.24 (1.04–1.50); p = 0.020) and higher health-care utilization (OR = 1.29 (1.10–1.51); p = 0.001). Our study highlights the need for rationalization of FRID use. To reduce the unnecessary exposure to FRIDs in older adults, health-care professionals must consider high individualization of medication schemes regarding selection, dosing, and combinations of only necessary FRIDs.

Published: November 2024

Parkinson disease (PD) is a neurodegenerative movement disorder. Beginning with Braak’s theory that hypothesized a connection between gut, inflammation, and substantia nigra degeneration, many studies were made to put a link between inflammatory bowel disease and P D. We studied several patients with advanced PD, submitted in our Neurology Center, between July and September 2022 for initiation of device aided therapy with intestinal gel that fulfilled the admission criteria. We took under consideration the demographic data, UPDRS motor part III, ADL and IADL scales at day 1, after discharge and after 3 months. We provided biological analysis for D-Dimers, Fibrinogen, C Reactive Protein, ESR, and we compared the values from the 1st day of hospitalization and after 3 months; fecal samples were collected to evaluate the presence and the levels of fecal calprotectin (FC). In more than 60% of the cases, fecal calprotectin was higher than 100 ug/g (5 times normal), 80% more than 400, 20% more than 1000 ug/g, associating with modified inflammatory marks and clinical evaluation scores with no significant improvement in motor abilities in 3 months after discharge. In only 2 cases where calprotectin was below 22, there was a positive evolution in UPDRS motor part III score from 52 to 36 and from 29 to 21(from day 1 and after 3 months), alongside with 2 points in ADL, IADL scales. Inflammation biomarkers and fecal calprotectin in high ranges seem to associate difficulties in obtaining a good therapeutical response in advanced PD stages.
A Sustainable Approach to Teacher Professional Development on Self-Regulated Learning (SRL) Implementation
Authors: Taranto Daniella
Published: November 2024

Self-Regulated Learning (SRL) is widely acknowledged as essential for educational achievement and fostering continuous learning skills (Taranto & Buchanan, 2020). As a result, there has been a marked escalation in embedding SRL criteria within academic curriculums, including primary education (De Smul et al., 2020; Heirweg et al., 2021). However, implementing SRL poses a significant challenge for educators, as it requires them to focus not just on delivering content but also on guiding students through the process of strategic learning. Teachers require specialised knowledge and expertise in effectively teaching SRL (De Smul et al.,2019). Understanding how to offer teachers support for effectively implementing SRL into classroom settings represents a vital area for future research (Dignath, 2021; Greene, 2021; Karlen et al., 2020). To this end, the current study investigated teachers’ understanding of acquiring professional expertise in implementing SRL within Grades 5 and 6 classrooms. The research was conducted in a Catholic primary school in Victoria, Australia, employing a comprehensive SRL approach to teaching and learning practices. To gather insights from the participants, unstructured interviews were conducted. The methodology of Classic Grounded Theory (Glaser & Strauss in 1967) was applied to identify, conceptualise, and examine the participating teachers’ perspectives. This study demonstrated the preference among teachers towards a multifaceted approach to SRL-focused professional development (PD) for enhancing critical aspects of teacher knowledge they deemed vital for SRL implementation. Furthermore, the findings emphasised the significance of teachers participating in training sessions to enhance their SRL content knowledge, team teaching opportunities centred on SRL pedagogical content knowledge and teacher coaching that emphasised teachers’ experiences with practising SRL. The research underscored professional expertise in SRL implementation as an incremental process of cultivating specific areas of professional knowledge that relied on diverse approaches to PD and required a sustained approach.

Authors: Siagian Pariang
Published: November 2024

The pharmaceutical industries are crucial for the nation’s health and economy; therefore, their performance must be maintained. When they obtain the more successful performance indicators that can sway investors to raise their confidence as well as market value. This study aims to examine the effect of the Fama-French five factors and environmental performance on share returns. This was conducted on pharmaceutical industries listed on the Indonesia Stock Exchange, and all data was obtained from annual-quarterly reports in the period 2017–2023. A total of 196 panel data observations have been conducted, and the analysis technique has employed quantitative approaches, notably autoregressive distributed lag analysis, of time series data. The results showed that market risk premium (MRP), firm size (SMB), profitability (RMW), and environment performance (EP) have a significant impact on share returns (SR), while firm size (SMB) and book value to equity (CMA) have not been significant statistically. The study is important for a variety of stakeholders, including managers, investors, and policymakers, who are interested in resolving the financial and environmental performance of pharmaceutical companies and preserving market prices by establishing mitigation strategies related to the specific factors. However, this study has limited relevance to the presence of F-F five factors and environmental performance that cannot maximally encourage the disclosure of market value.

Published: November 2024

With a harmonious pattern between the workforce and the company, job satisfaction will result. East Kalimantan is very popular for its abundant natural resources, including mining. Referring to the terminology above, this paper focuses on the causality between training and rewards on employee productivity by involving job satisfaction as a mediator. The focus of this paper is one of the largest companies operating in the mining sector located in the Balikapan area. The assessment was carried out by distributing an open questionnaire to 346 employees who worked at the company. The quantitative approach is implemented in Smart-PLS, where the output is two schemes (outer model and inner model). In general, the statistic analysis finds that training and rewards have direct implications for employee job satisfaction and productivity. At the same time, job satisfaction does not have direct implications for employee productivity. Unfortunately, job satisfaction is unable to mediate the relationship between training and rewards on employee productivity. In essence, although training and rewards function in stimulating job satisfaction and employee productivity, they have not been proven optimal in encouraging employee productivity which is mediated by job satisfaction. Therefore, companies need to prioritize job satisfaction with more comprehensive proportions.

Published: November 2024

Climate change and its impact on the economic and social welfare is a vitally important problem explored everywhere in the modern world. The objective of this research is to determine a correlation between the amount of carbon dioxide emissions in Ukrainian regions and their economic and demographic indicators: gross regional product, turnover of business entities and population density. The study is focused on CO2 emissions from stationary pollution source. The article provides evidence-based arguments that circular economy is the model integrating two central objectives: economic growth and mitigation of effects from climate change. The study revealed a strong correlation between the implementation of circular economy practices and objectives of Sustained Development Goas, in particular with respect to minimization of СО2 emissions. A statistical analysis of the relationship between СО2 emissions and gross regional product (GRP), turnover of business entities and population density at the level of Ukrainian regions was made. It was revealed that all the Ukrainian regions with high rates of per capita GRP growth there is no tendency to increase CO2 emissions. This complies with circular economy priorities: minimization of resource extraction through processing and re-production. The regions with a higher population density were revealed to have lower СО2 emissions, which can be attributed to the fact that a higher population density often entails a more compact urban habitat. The regions with the largest turnover of business entities include regions with their highest population density. Economically developed regions often push technological innovations with breakthrough effects for energy technologies, transport and industrial processes, which help reduce CO2 emissions.

Interprofessional collaboration (IPC) is important for shaping healthcare to meet the increasing demands of the health care system. Interprofessional (IP) training approaches are increasingly being pursued in the education of healthcare professionals (HCPs). The Zurich interprofessional clinical training ward (ZIPAS®) is implementing this approach in HCP’s education. This study is part of the evaluation and explores fostering factors for perspective taking among students during ZIPAS®-internships.

84 HCP-students who participated in the ZIPAS®-program between 2018 and 2022 took part in this study. Semi-structured focus group interviews with the students and their facilitators were conducted and analyzed thematically. This study focuses on the category “benefits” and its subcode “perspective taking”.

In the coding of perspective taking, getting to know the competences of others was mentioned the most by students, followed by work shadowing and understanding others. This was promoted through willingness to learn, communication, openness of the students, and spatial proximity.

ZIPAS® created a safe space for students to learn IPC. A shared office is a strong fostering factor of perspective taking and IP information sharing. Positive expectations promote perspective taking and therefore are a learning benefit. The ZIPAS®-program provides learners with valuable experiences and enhances interprofessionality. IP clinical education in real settings should become an educational standard for HCP-students.
From Measuring “Integration” to Representing “Superdiversity”
Authors: Bevelander Pieter
Published: November 2024

International migration to Sweden and its larger cities has been substantial over the last six decades. In particular, the last three decades have seen a growing number of individuals settling in the third major city of the country, Malmö, whose population now originates globally. University education on the topic (IMER) at Malmö University and research conducted at the Malmö Institute for Migration Studies has kept pace with these demographic and societal developments, including through the development of the Migration Society 2.0 database, a unique database built on a recurring survey that will help enhance our knowledge and understanding of the patterns of migration-induced diversity, inclusion and exclusion that characterize Sweden.
The Chronopolitics of Migrant Temporalities
Authors: Kierulf Gavin
Published: November 2024

This paper seeks to understand the relationship between migrants’ journeys and time as a distinctly political phenomenon. By drawing on conceptualizations of temporality developed in queer theory and sexuality studies, the chronopolitical continuities of migrant’s journeys are drawn out. Moreover, to better analyze the problematizations which arise from inquiry along temporal lines, this paper takes on scholars Brigden and Mainwaring’s concept of ‘Matryoshka Journeys.’ Understood on these terms, migrant journeys are made up of moments of temporal experience, characterized by interrelated occasions of advancement, deceleration, and waiting. By interrogating the relationships between these temporal aspects of migrant journeys, and by using select examples to further illustrate these relationships, this paper concludes that the chronopolitical nature of migrant temporalities can be understood as a kind of ‘temporal governance’ made possible by the separations between ‘settled’ temporalities and ‘migrant’ temporalities maintained by border regimes which – through cycles of deportation, (de)prioritization, and carcerality – sustain waiting as a fixture of migrants’ journeys, and their (re)victimization.
Value Added Tax Collection Efficiency and Economic Activity
Authors: Liko Elida
Published: November 2024

Objective: Revenue enhancement through improving the tax efficiency generates more income for the government without increasing the tax burden, and sustain economic growth. The objective of this study is to investigate the relationship between value added tax collection efficiency and growth.
 
Theoretical Framework: Endogenous economic growth model allows for investigating the effects of fiscal policy on growth. In tax literature, indirect taxes are considered close to growth because they do not discourage saving and investment. The study decomposes the VAT revenues and use the VAT C efficiency to estimate the impact on growth.
 
Method: The methodology adopted for this research is based on structural vector autoregressive SVAR. SVAR allows us to impose structural restrictions according to economic theory and to analyze the impact that an individual shock has on other variables included in the model.
 
Results and Discussion: The study found that value added C -efficiency has a small and positive impact on growth, only in the short term. The maximum effect is in the third quarter, when one percentage point improvement in collection efficiency, increase the real per capita GDP, about 0.3 percent. Further improvements in collection efficiency are needed to generate more tax revenues and sustain growth. The study also found that total tax to GDP has a positive impact on growth, that is significant only in the short time. Government expenses have supported economic growth. An increase in government expenses as a percentage of GDP, is followed by an improvement in real per capita GDP with about 1.05 percent, average impact.
 
Research Implications: The present research uses four fiscal variables, and only inflation rate based on GDP deflator as a control variable. Further research could be extended by including other control variables.
 
Originality/Value: This study contributes to the tax literature in developing countries by estimating the impact of VAT on growth using C -efficiency ratio.

Published: November 2024

Purpose: Job satisfaction among young employees is crucial for organizations, as it positively influences productivity and well-being. This study explores the factors associated with job satisfaction among employees aged 20 to 30 in organizations in Medellín-Colombia.
 
Design/methodology/approach: Data was collected from 400 young employees across various organizations in Medellín, a pilot test ensured the reliability of the instrument using Cronbach’s Alpha. A CUB model was used to identify key factors affecting job satisfaction.
 
Findings: Professional development (PD) and workload (WL) appeared as significant factors influencing both job satisfaction and the intention to stay, while Leadership quality persepction of superiors (LQ) lacked individual statistical significance, they contributed to the overall model's significance.
 
Practical implications: Organizations should foster professional development and manage workloads effectively to reduce turnover among employees aged 20 to 30.
 
Originality/value: Although job satisfaction has been widely studied, little attention has been given to young employees. This research bridges that gap by analyzing the social-psychological factors influencing their job satisfaction and intention to stay, offering insights for HR managers and organizational leaders.

Published: November 2024

Objective: The aim of this study is to assess the air and water permeability of soil mixtures with organic compost in different proportions in order to determine the gas and liquid fluxes for use in landfill cover layers.
 
Method: The methodology adopted for this study includes laboratory tests to characterize the materials and the use of the flexible wall permeameter model Tri-flex 2 from Soil Test – ELE to determine the air and water permeability of the materials. Mixtures in proportions of 2:1 (soil:compost) and 1:1 (soil:compost) were used as materials for the oxidative covering layer.
 
Results and Discussion: Based on the results obtained, it is possible to conclude that the mixtures present permeabilities to air and water in accordance with the standards indicated by USEPA (2003) for covering layers in sanitary landfills, thus ensuring that there is no excess percolation of water from rain, as well as the emission of polluting gases into the atmosphere.
 
Research Implications: The studied material is potentially suitable for use in oxidative cover layers for sanitary landfills, proving to be a viable alternative for implementation in smaller municipalities with less purchasing power, reducing the need to use clay materials, without detriment to the operational efficiency of the landfill.
 
Originality/Value: One of the difficulties faced by municipalities in using sanitary landfills is the search for suitable materials, especially in municipalities with lower purchasing power or located in arid regions, where the use of conventional layers presents problems, with drying out and opening of fissures. The relevance and value of this research are evidenced by the feasibility of combining clay soils with organic compost to create oxidative cover layers, reducing the pollutant load of organic waste.

Cause-and-effect relationship between elements of the country's economic security
Authors: FEOFILOVA Tat'yana Yu.
Published: November 2024

Subject. I present my own concept of the country's economic security structure, the elements of which are economic stability, economic independence, and economic sovereignty. The article considers the problem of forming a system of indicators designed to assess economic security.
Objectives. The article focuses on the analysis of Russia's historical experience in the interaction with the International Monetary Fund for 1990–1999.
Methods. The study draws on comparative analysis, observation, and modeling.
Results. The adoption of the recommendations of the International Monetary Fund by the Government of the Russian Federation, as well as the loss of economic stability, contributed to the loss of economic sovereignty. The paper confirms that the loss of economic stability leads to the reproduction of threats to economic independence and sovereignty. The loss of economic sovereignty increases the threats of loss of independence and stability. A decrease in the degree of independence contributes to the reproduction of threats to sovereignty and stability.
Conclusions. Elements of the structure of economic security have cause-and-effect relationships and intersection zones, which should be taken into account when developing a system of indicators to measure the stability, independence and sovereignty of the national economy.

Authors: Ragavan K V Santhosh , Revi Aromar , Sudhakar Srinithi , Vijendra Mahima , Vimala P. P. , Wankhade Kavita
Published: November 2024

Significant gaps and inequities in urban water and sanitation services persist, with a growing risk of exacerbation due to changes in the climate, global water cycle, and patterns of urbanisation. Urban water and sanitation systems need to transition to accelerate access to safe, equitable, and sustainable water and sanitation services, while enhancing resilience to respond to increasing risks. This paper reviews the persistent challenges in water and sanitation services, emerging risks from climate change, and imbalances in the global water cycle that threaten to impact urban water cycles, and potentially disrupt existing urban Water, Sanitation and Hygiene (WASH) systems. It identifies critical concerns in three areas: institutional arrangements (including informal service provisioning), technology and infrastructure, and financing (including operations and maintenance). The paper concludes by identifying critical elements required in these areas for successful transition of water and sanitation services and systems.

This research paper explores the critical role of teacher agency in the implementation and effectiveness of plurilingual strategies in educational contexts. It investigates how teachers’ beliefs, identities, and capabilities influence their adoption of plurilingual methods and assesses the impact of these factors on curriculum design. The discussion focuses on the dualistic nature of teacher agency, which can both enable and limit teachers as they deal with the complexities of plurilingual education. The paper reviews literature that illuminates the challenges and possibilities created by teacher agency, providing insights into how it shapes educational strategies and outcomes. It offers recommendations on how teacher education programs can leverage this agency to enhance plurilingual education effectively. This paper not only clarifies essential concepts but also critically examines the role of agency in advancing plurilingual educational practices, deepening the understanding of its application across educational settings.
Cali Salsa Forever
Authors: Quintero Rafael
Published: November 2024

El fenómeno de la música salsa en Cali ha sido objeto de controversias, hitos y mitos, que paradójicamente han venido enriqueciendo esta importante tendencia musical que llegó a la ciudad en los barcos, y se quedó para siempre. Justamente, Cali: Salsa Forever despeja esta discusión en el barrio. Partiendo de la pregunta: ¿Por qué nuestra ciudad adoptó la música del Caribe que se desarrolló con mayor ahínco en Nueva York?, Rafael Quintero hace un viaje por la música del Caribe en Cali, desde los años cuarenta hasta los años setenta, y revela aquella tesis que alguna vez dijera el escritor cubano Alejo Carpentier en el sentido de que un país no se define por sus fronteras geopolíticas sino por sus regiones geoculturales. El libro de Quintero es una deliciosa crónica, fácil de leer, que se sustenta en referencias históricas y de sus protagonistas. Es un ajuste de cuentas con aquellos que creen que la salsa llegó a Cali y se quedó para siempre. Cali: Salsa Forever es un libro necesario que hacía falta para ponerle punto final a tanta hipocresía y tanta vanidad, como diría Eddie Palmieri. Nos da luces de navegación para comprender mejor la cultura caleña que hace parte de aquella diáspora musical que se originó en un bohío cubano, viajó hasta Nueva York y retornó a nuestras raíces para quedarse para siempre. Cali: Salsa Forever es un homenaje a Cali, a nuestros padres y a nuestros hijos. -Fabio Martínez Siempre me enamoró su forma exquisita de escribir. En su libro encontraremos la verdad de la Salsa en Cali, en un periodo fundamental de su historia. -Gary Domínguez
Operational Noise Abatement Through Control of Climb Profile on Departure

This work introduces a noise abatement procedure for reducing aircraft community noise during departures based on the control of climb profiles via procedural level-offs. The proposed procedure consists of enforcing an altitude restriction along a departure path such that aircraft maintain level flight when overflying strategically selected regions. During this level segment, thrust demand is lower than during climbing flight, which results in lower engine noise. However, this effect must be balanced with the lower aircraft altitude in the level segment, which may reduce the distance between aircraft and observers. Thus, a systematic analysis methodology is needed to design an effective noise abatement procedure based on this technique, which has been developed and is presented in this paper. Modeling results show potential undertrack peak A-weighted noise level reductions of 2–4 decibels for both narrowbody and widebody aircraft in the level-off area depending on the level-off altitude and an associated increase of 1.5–6 decibels in the region where the climb is resumed. An example application of this procedure is demonstrated at Boston Logan Airport, with cumulative changes in noise impacts being assessed for one full day of operations. In this example application, fuel burn penalties are estimated at 37 pounds for a representative narrowbody operation and 142 pounds for a representative widebody operation.

To address the challenges associated with existing space solar power station (SSPS) concepts, including noncompact structural design, nonuniform solar energy flow density, and orbital deployment complexities, an integrated, highly modular, flat functional structure based on the Miura origami pattern is proposed. The flat functional structure consists of a flat quadrilateral Fresnel concentrator for solar energy collection, a photovoltaic array for photoelectric conversion, and a transmitting array for microwave power transmission. To optimize space utilization and enhance the deployment ratio, the Miura origami pattern is introduced, and the subarray composed of multiple flat functional structures can be packaged in a payload capsule before launch and unfold as a standard rectangle with uniform thickness and a flat surface in orbit, improving the transportability of the launch vehicle. Additionally, to solve the nonuniform solar energy flow density, a Fresnel concentrator was employed to achieve uniform irradiation, while the transmitting array was designed to achieve good electrical performance. Finally, the structural parameters and efficiency of the SSPS system composed of multiple subarrays are presented in detail.

Background: Prematurity is a serious public health problem, due to its high morbidity and mortality, with 15 million premature births and one million deaths annually worldwide. The main causes of neonatal mortality in premature infants are necrotizing enterocolitis and late sepsis. In Peru, the percentage of premature births increased from 6.4% in 2020 to 7.5% in 2023, with an average of 30,000 premature newborns annually. In 2023, 70% of neonatal deaths corresponded to premature babies. The National Maternal Perinatal Institute reported high rates of neonatal mortality, especially in premature babies weighing less than 1500 grams. It is worth mentioning that of all neonatal deaths by 2023, 70% corresponded to premature babies and 46.5% to those less than 1500g. Objective: Determine the protective effect of colostrotherapy in premature newborns with birth weight less than 1500g in the INMP during the period 2018-2021. Methods: Longitudinal analytical observational and retrospective cohort study. The bivariate analysis was carried out, where the presence of the association between the variables and the administration of colostrotherapy was evidenced. In the multivariate analysis, 3 study models were proposed (model 1: necrotizing enterocolitis, model 2: requirement for mechanical ventilation and model 3: mortality), and Poisson-type multiple logistic regression was used, indicating the adjusted relative risk and its respective 95% confidence intervals. Results: In the multivariate analysis, the 1st model showed that colostrotherapy (adjusted RR: 0.304, 95% CI: 0.099-0.93) acts as a protective factor against necrotizing enterocolitis. In the 2nd model, colostrotherapy showed no association with the requirement for mechanical ventilation. And finally, in the 3rd model it was shown that colostrotherapy (RR: 0.494, 95% CI: 0.32-0.76) acts as a protective effect with respect to mortality. Conclusions: The administration of oropharyngeal colostrum is a simple and safe procedure, it can reduce the incidence of necrotizing enterocolitis and mortality in premature neonates less than 1500g.
