Authors: Reyes-Fernandez Diana Laura , Lugo-Machado Juan Antonio 
Published: February 2025

Abstract
OBJECTIVES. To assess the association between tympanoplasty outcomes and the Middle Ear Risk Index (MERI).
MATERIAL AND METHODS. Observational, retrospective, analytical, and cross-sectional study. The files of the operated cases were reviewed, and demographic, clinical and MERI parameters were included. Descriptive statistics and measures of dispersion were used. To assess associations, Pearson’s chi-square test was applied, with a significance level set at p ≤ 0.05.
RESULTS. A total of 82 files were included, with an average age of 43.12±16.9; 67% of the patients were women and 51.2% had comorbidities. The most used technique was overlay in 76.8%, with the temporal fascia being the most frequently used graft in 81.7%. The degree of middle ear disease was mild in 41 patients (50%), moderate in 28 (34.1%), and severe in 13 ears (15.9%). An association was found between the degree of MERI and surgical success, with a p -value of 0.02.
CONCLUSION. It seems that the index is associated with the graft outcome at 6 months. Moderate MERI appears to be linked to lower success rates.

Abstract
Germany is facing demographic change, with the number of people in employment set to fall significantly by 2050. A sustainable education policy is crucial to counteract the shortage of skilled labour. Early investment in education, especially in disadvantaged families, is particularly effective according to skills formation theory. Families and day care centres play a central role here. In order to reduce educational inequalities, measures such as the expansion of early childcare, better support for parents and standardised quality standards for daycare centres are required. An education fund could ensure long-term, equivalent provision.

Abstract
We discuss the importance of a sustainable education policy for the prosperity and stability of society. Early childhood education, schools and vocational training must all be seen as a lifelong learning project in order to promote equal opportunities. Despite the expansion of day care centres and schools, inequalities in access to education persist, especially for children from disadvantaged backgrounds. Vocational education and training is under pressure as the number of trainees is falling and there are matching problems. Education policy must therefore be inclusive in order to open up educational and career opportunities for all.

Abstract
The German economy is stuck in a structural crisis, with GDP hardly rising above its pre-COVID-19 level. In the run-up to the federal election, political parties propose various incentives for private investment and disagree about the extent of the intended stimulus for the corporate sector. The article examines the overall economic effects of these measures, the impulses for investment activity and the efficiency of the instruments. While the measures envisaged by FDP and CDU/CSU have the strongest economic impulses, the measures taken by SPD and the Greens are more targeted and therefore more efficient.
Institutions Matter – Nobelpreis 2024 an Daron Acemoğlu, Simon Johnson, James Robinson
Authors: Sauerland Dirk 
Published: February 2025

Abstract
Daron Acemoğlu, Simon Johnson and James Robinson were awarded the Nobel Prize in 2024 for their research on the impact of institutions on the prosperity of nations. They expanded the classical economic theory of market mechanisms, capital accumulation and technology to include the institutional and political-economic dimension. By skilfully identifying natural experiments, they show how inclusive institutions promote long-term prosperity, while extractive institutions lead to instability. The choice of institutions – not geography – determines economic success. Various critiques of their work demonstrate how they advance the debate, address their identification, the role of property rights and the insufficient differentiation between countries with similar institutional structures.

Published: February 2025

Kirkuk province needs a comprehensive and specialized strategy to address these difficulties and identify the most suitable solar energy solutions to reduce its ecological impact and improve its energy security and economic sustainability in future years. This study aims to present a framework for solar energy farm site selection working with Geographic Information System (GIS) and Multi-Criteria Decision Analysis (MCDA) techniques surrounding Kirkuk province, Iraq. Several spatial data sets were integrated in two steps to locate the best locations for solar energy farms. The first stage was to identify land availability with the elimination of constraints areas such as distance from major roads, distance from bodies of water, urban areas, distance from electric power transmission lines, and distance from industrial locations. The second stage was to choose the essential criteria, weigh them using an Analytical Hierarchy Process (AHP), and finally analyze the criteria using GIS to determine the best sites for solar energy farms. The available land results indicated their distribution in three regions with large areas, which are the north-east, north-west, and south-east, with a total area estimated at 40.182 km2, in addition to separate small areas of about 1.698 km2 in the rest regions of the study area. The highly suitable lands were dispersed throughout the northwest and north of the research region, covering a total area of 7.4304 km2, while medium suitable lands, indicated by the yellow color, are spread out in the southeast, with a total area estimated at 2.9376 km2. The low suitable lands cover some small areas south of the research area, shown in green, and cover an area of 1.8432 km2.

Based on an analytical study of a set of patented technological solutions, a methodology for assessing the quality of ASW as an object of processing and disposal is proposed. A rationale for the feasibility of using such a methodology is given. Resource-saving technologies for waste processing that have undergone pilot and pilot testing are presented. The reasons for the feasibility of largescale involvement in the processing and disposal of technogenic raw materials concentrated in artificial accumulations of waste that pollute the environment are considered. It is noted that resource efficiency characterizes the resource-saving system in terms of the degree of waste utilization and the quality of the resulting products (while minimizing costs and environmental risks). The criteria for resource efficiency of waste and secondary raw material processing are noted: the degree of waste utilization, technological indicators of the processes used, indicators of new products, specific energy consumption. An assessment of resource efficiency is given using ASW as an example. The fundamental directions of ASW processing and disposal and ways to improve their quality as secondary raw materials are shown.

В данной статье представлен обзор советских и российских разработок, и текущие состояние дел. Вопрос повторного использования ступеней или всей ракеты-носителя (РН), был актуален еще в первые годы разработки ракетно-космической техники (РКТ). Повторное использование РН является одним из немногих путей в уменьшении стоимости запуска полезной нагрузки и стоимости эксплуатации изделий РКТ в целом. Многие конструкторские бюро и исследовательские институты по всему миру проводили исследования и испытания различных систем посадок. Основным вопросом при разработке многоразовых РН является выбор принципиальной схемы посадки.
This paper presents a review of Soviet and Russian developments and the current state of affairs. The issue of reuse of stages or the whole launch vehicle (LV) was relevant in the early years of space rocket technology (SRT) development. The reuse of boosters is one of the few ways to reduce the cost of launching payloads and the cost of operating RCT products in general. The main issue in the development of reusable boosters is the choice of the principle landing scheme. Many design bureaus and research institutes around the world have conducted studies and tests of various landing systems.

Data on the content of one of the groups of persistent organic pollutants – polybrominated diphenyl ethers (PBDEs) in various types of technogenic substrates obtained for the first time for Belarus are discussed. The objects of the study were chemical enterprises where PBDE-based flame retardants were used, enterprises for the production of computers and household equipment, mechanical engineering and other industries potentially using materials containing PBDEs, sites for collecting and processing waste electrical and electronic equipment, waste landfills, waste water sewage sludge (WWSS) storage sites. 40 samples of technogenic substrates and 17 samples of WWSS were taken and analyzed. Chemicalanalytical determinations of PBDEs were performed using gas chromatography methods with mass spectrometric detection. Additionally, the content of bromine and antimony as indicators of the brominated flame retardants use was determined using X-ray fluorescence spectroscopy. It was shown that PBDEs were detected in 33.3 % of samples with maximum values of 5.11 mg/kg, bromine – in 40.4 % (236 mg/kg), antimony – in 15.8 % of samples (maximum value of 319 mg/kg). PBDEs were found in WWSS, technogenic substrates and silt deposits in impact zones of various local sources. The main routes of hazardous substances release into the environment and the most likely sources of brominated persistent organic pollutants (POP) are discussed. The need to develop a methodological base for environmental-geochemical studies in Belarus is shown.

Sphenoid sinus is one of four air-filled spaces inside cranium bones, which drain into the nasal cavity. It has high individual anatomical variability, including sexual dimorphism, ethnic and geographic variations in morphometric parameters.The purpose of the study was to establish the dependence of the morphometric parameters of the sphenoid sinus on its extent in the dorsal and lateral directions.Сone beam computed tomography (CBCT) data of 245 patients (98 males and 147 females, mean age 37 ± 13 years) who received dental and ENT care at a private medical center in Minsk in 2023–2024 were assessed.The postsellar type of the sphenoid sinus was more frequent in males and females (71.4 and 66.6 %, respectively). The volume of the sinus in the present study varied between 3.4–37.5 cm3. It was larger in males. In patients under 30 years of age, the volume and width of the sphenoid sinus were significantly larger compared to patients 31–84 years old. All linear dimensions of the sinus were significantly larger in the postsellar type. The width and volume of the sinus were significantly larger as lateral expansion into the greater wings of the sphenoid occurred. In 56.7 % of patients, the sphenoid sinus was divided by the septum into right and left parts, most often asymmetric. In 11.0 % of cases, one air cavity was detected. In 32.3 % of patients, in addition to the main septum, accessory septa were present, which in about half the cases were inserted at the wall of carotid prominence.Due to the high variability of the morphometric parameters of the sphenoid sinus, when considering the possibility of an endoscopic transsphenoidal approach to the skull base, a thorough preoperative CBCT examination of the sinuses is recommended.

Authors: Małysa Tomasz 
Published: February 2025

Abstract
The issue of safety in the use of machinery is an important issue for both manufacturers and employers. The current legislation imposes a number of obligations on manufacturers (essential requirements) and employers (minimum requirements) related to ensuring safety at every stage from design to operation. The study analyzes the possibility of applying selected Lean Manufacturing tools to improve occupational safety in the use of machinery (work equipment). The purpose of the study is to present the possibility of application of selected LM tools on operator safety, as well as to meet the requirements of legislators relating to safety related to the use of machinery. Implemented LM solutions improve communication and organization of work, and most importantly, reduce the risks associated with the operation of machinery and equipment.

Abstract
This study examines the relationships between lean manufacturing, green supply chain management (GSCM), supply chain resilience (SCR), and firm performance in Thai manufacturing companies. Using data from 322 employees across various industries, the research employs co-variance-based structural equation modelling to test a series of hypotheses. The findings reveal that lean manufacturing has significant positive effects on both GSCM practices and firm performance. GSCM practices demonstrate a strong positive impact on SCR. However, contrary to expectations, the study finds no significant direct relationship between GSCM practices and firm performance, nor between SCR and firm performance. The hypothesized mediating roles of GSCM practices and SCR in the relationship between lean manufacturing and firm performance are not supported. These results suggest that while lean manufacturing and GSCM practices contribute to improved operational efficiency and environmental sustainability, their translation into enhanced financial performance may be more complex than previously thought. The study contributes to existing literature by providing empirical evidence from the Thai manufacturing context and highlights the need for further research into how operational improvements in lean and green practices can be converted into tangible financial outcomes.

Published: February 2025

Abstract
The article analyses studies on the impact of the COVID-19 pandemic on outpatient services in a large hospital, aiming to provide insights for resource management amidst disruptive events. The objectives include identifying challenges and proposing solutions to optimize service delivery and address spatial constraints using discrete-event simulation. Utilizing a case study approach, the research employs simulation as a key methodology to analyse outpatient service scenarios. Scenarios are generated by combining different probabilities of patient return to check-in with various team parameterizations. The researchers analysed historical data and key performance indicators from the simulation. The study focuses on a collaborative approach with the hospital team to ensure the relevance and applicability of proposed solutions. The research identifies bottlenecks induced by social distancing measures, particularly in patient reception and check-in areas. Uneven service distribution throughout the day leads to a misallocation of resources and reduction of available physical space. Telemedicine emerges as a significant response, effectively addressing both service optimization and physicians’ workload despite spatial constraints. Additionally, the study underscores the role of simulation in crisis decision-making for hospital operations management. Practical applications emanating from the study emphasize the need for healthcare institutions to adopt adaptable strategies and leverage simulation tools for effective resource management during disruptive events. Hospital administrators can draw insights to inform resource reallocation and workflow optimization, with a focus on negotiating flexible scheduling and exploring telemedicine to enhance service delivery.
