Architectural Enablement for Time Sensitive Communications
Authors:   DDC-I Inc., Gilliland Gary
Published: August 2024

Deos includes an industry standard lightweight TCP/IP stack (LwIP) with a DAL-A sockets library so it can provide data transport during in flight or on ground as part of its standard package. While it may have high data integrity (e.g., through CRC or other such mechanisms), TCP/IP over Ethernet is a non-deterministic protocol. As such, it is not suitable for avionics applications that require determinism or high robustness.
In contrast, there are several are several redundant and deterministic data network technologies such as ARINC-664/AFDX, time triggered ethernet (TTE), and time sensitive networking (TSN). These interfaces are based on switched Ethernet technologies and can include system redundancy such that they are applicable for aircraft data network applications. Their feature set enables them to be used as a digital backbone for aircraft control and other applications where both integrity and availability are essential.
Each of these solutions generally requires specific end point hardware to implement the protocols in firmware in order to meet the required communication timing and throughput. The implementation of the software device drivers for these technologies on Deos can leverage Deos' I/O Infrastructure (IOI) data distribution service for data decoupling. IOI is a DO-178 DAL-A module that can distribute data based on XML configuration files that specify the data paths, access control and optionally data formatting. It implements an inter-partition communications data interface between avionics applications including ARINC-653 partitions using the ARINC-653 APEX API sampling/queueing ports. Together, these features allow developers to readily adapt to changes in communication structures all through XML configuration files, versus recompiling which would impact the verification evidence of the module.

This paper will talk about the different networking standards and how the use of Deos' IOI provides a way for the system to easily adapt to different network configurations without causing the driver library or end application(s) to be modified and thereby minimize change impact for reuse/reverification.

Published: August 2024

The purpose of this paper is to present the technical details of the US Army Program Executive Office - Aviation (PEO AVN) Enterprise Architecture Framework (EAF) while describing its development status as of January 2024. The Future Vertical Lift (FVL) Program developed and continues to improve the FVL Architecture Framework (FAF) (Ref. 1) for use by FVL programs. The EAF is intended to be compatible with the FAF and to provide specific guidance to enduring programs. The EAF contains modeled content from the FAF and employs a technical approach that contains different perspectives for enterprise (i.e., PEO AVN) and program users depending on how the EAF will be used. As an architecture framework, the structure of the EAF follows International Standard ISO/IEC/IEEE 42020 (Ref. 2). The EAF prescribes the conventions, principles, and practices for the development of the Enterprise Architecture (EA). The EA communicates the technical, business, and organizational architecture of the enterprise for the purpose of enabling Modular Open System Approach (MOSA) (Ref. 3) objectives, such as improved affordability, increased readiness, enhanced capabilities, reduced schedule pressure, and reduced supply chain risk.

Authors:   UMBRAGROUP S.p.A, Biagetti Francesco , Borgarelli Nicola , Malleret Frederic , Pelliccia Stefano
Published: August 2024

The paper deals with the status of development and qualification/certification of electromechanical actuation for Helicopters and VTOL applications with the focus on aspects relevant to the Fault-Tolerance. In particular a linear Electromechanical Actuator (EMA) architecture is presented, derived from a fault tolerant ballscrew-based differential (speed-summing arrangement) actuation system patented by UMBRAGROUP S.p.A. The focus is on safety-critical and high reliability/availability requirements for electromechanical actuation certification.
The main characteristic is the use of two independent mechanical actuation channels in the same envelope driven by independent Motor Control Electronics (MCEs). At the state of the art, the presented fault-tolerant architecture is under development in flight-critical swashplate application for eVTOL platform and under feasibility study in flight-critical swashplate application for CS27 platform.
A Pragmatic Approach to DO-178C-Inclined Software Development for Lift-to-Cruise Aircraft Nonlinear Flight Control
Authors:   University of the Bundeswehr Munich, Panchal Purav , Surmann Denis , Myschik Stephan
Published: August 2024

Systems whose failure or defective behavior can lead to either the loss of human life, serious injury, environmental harm, or significant equipment or property damage are referred to as safety-critical systems. Considering the impact that these systems have on human safety, it is necessary to thoroughly verify their behavior and rigorously test them before exposing them to the public. In aviation, the development of such safety-critical software, such as a flight controller or a battery controller, requires adherence to stringent methodologies to formally certify the software according to standards like DO-178C/DO-331. One such safety-critical flight controller software, based on the incremental nonlinear dynamic inversion (INDI) approach, is being developed for an electric vertical take-off and landing (eVTOL) aircraft. This aircraft features a fixed-wing configuration with a wingspan of 2.1 meters and is equipped with an electric propulsion system consisting of two propellers and one impeller. The complete software development toolchain used for this flight controller development is presented, along with the necessary requirements-based verification results. The research showcases the model-based software development and static model and code verification results.

Published: August 2024

This paper describes the methodology, involving testing and simulation activities, to assess malfunction conditions of complex systems installed on fly-by-wire vehicles, including the evaluation of their effects. This paper provides also a description about how the system malfunction tests are designed, driven by input requirements and systems capability and behavior. With respect to prior publications, this paper includes some practical test examples, based on systems monitoring, logics and alerting functions. The case study described here comes from a portion of multiple laboratory certification tests done for AW609 Tiltrotor, focused on Avionics System malfunctions. These tests and simulations are a valuable Means of Compliance with respect to applicable airworthiness rules, and a suitable means to verify the design safety requirements. Three relevant examples are presented, grouped by input requirement and safety conditions. The effect of such malfunctions is evaluated, with respect to the Avionics System output produced to keep adequate flightcrew awareness about the vehicle status.
Mapping neonatal hearing screening services in Cape Town metro: A situational analysis
Authors: Louw Petronella H. , Odendaal Tara , Ramma Lebogang
Published: August 2024

Background: Childhood hearing loss is a global health concern. Despite the proven benefits of neonatal hearing screening (NHS), it is not yet mandated in South Africa. The lack of awareness of hearing loss and absence of NHS leads to delayed diagnosis and adverse developmental outcomes for affected children.Aim: The study aimed to assess the availability of NHS services across primary healthcare (PHC) facilities in the City of Cape Town (CCT).Setting: Surveys were conducted with 26 PHC facilities in the CCT metropolitan areas that offer mother and child healthcare services.Methods: Surveys gathered data through online and telephone methods. The surveys aimed to assess the availability and nature of NHS services, care pathways and training of healthcare professionals regarding NHS.Results: None of the facilities used objective screening methods to screen hearing or have standardised care pathways for at-risk babies. Instead, they relied on parental concerns, with the use of the Road to Health book. None of the respondents reported having received hearing screening training, and the majority of participants (62%) lacked confidence in their knowledge of ear and hearing care.Conclusion: The absence of NHS services highlights the need for standardised protocols and increased awareness among healthcare workers and caregivers. Implementing NHS services could facilitate earlier diagnosis and intervention of hearing loss for infants in the Western Cape.Contribution: This study’s findings could guide efforts to improving access to NHS access at PHC level in Cape Town, ultimately providing early hearing screening services to infants.
The resilience of rankings in the neoliberal academy
Authors: McKenna Sioux
Published: August 2024

The multi-billion-dollar university rankings industry purports to offer insights into the quality of institutions, but the extent to which it does so has consistently been refuted. Critics argue that problematic proxies, composite indexing, homogenising effects, and several other issues make them both unscientific and neo-colonial. This article outlines these criticisms and argues that if we are to understand the resilience of rankings, we need to acknowledge the context in which they have become ubiquitous. This article offers the prevalence of university rankings as an example of neoliberalism’s conditioning effects on the sector. It is not enough to demonstrate the problematic nature of rankings; we must also ask the question: what must universities be like for them to support rankings despite repeated evidence of their problematic nature? Answering this question should help us engage with the hold that rankings have over us, and it should also help us to imagine the university we want and need.Contribution: This article brings together literature on neoliberalism in the academy with that on university rankings. It argues that we can only understand the hold that the international rankings industry has by seeing the alignment between the rankings’ methodologies and aims on the one hand and the incursion of a neoliberal ideology across the higher education sector on the other.
On the Complexity of Target Set Selection in Simple Geometric Networks
Authors: Dvořák Michal , Knop Dušan , Schierreich Šimon
Published: August 2024

We study the following model of disease spread in a social network. At first,
all individuals are either infected or healthy. Next, in discrete rounds, the
disease spreads in the network from infected to healthy individuals such that a
healthy individual gets infected if and only if a sufficient number of its
direct neighbors are already infected. We represent the social network as a
graph. Inspired by the real-world restrictions in the current epidemic,
especially by social and physical distancing requirements, we restrict
ourselves to networks that can be represented as geometric intersection graphs.
We show that finding a minimal vertex set of initially infected individuals to
spread the disease in the whole network is computationally hard, already on
unit disk graphs. Hence, to provide some algorithmic results, we focus
ourselves on simpler geometric graph classes, such as interval graphs and grid
graphs.
A Note on Graph Burning of Path Forests
Authors: Tan Ta Sheng , Teh Wen Chean
Published: August 2024

Graph burning is a natural discrete graph algorithm inspired by the spread of
social contagion. Despite its simplicity, some open problems remain steadfastly
unsolved, notably the burning number conjecture, which says that every
connected graph of order $m^2$ has burning number at most $m$. Earlier, we
showed that the conjecture also holds for a path forest, which is disconnected,
provided each of its paths is sufficiently long. However, finding the least
sufficient length for this to hold turns out to be nontrivial. In this note, we
present our initial findings and conjectures that associate the problem to some
naturally impossibly burnable path forests. It is noteworthy that our problem
can be reformulated as a topic concerning sumset partition of integers.

Published: August 2024

Para observar la resiliencia se identifican cualidades del adolescente en un proceso de adaptación en su desarrollo, y así encontrar un sentido y crecimiento, aún en experiencias desfavorables. La resiliencia, desde la mirada de la psicología positiva de Seligman (2019), rompe con la visión negativa del proceso salud-enfermedad, y concuerda con procesos positivos del desarrollo humano; se centra en el bienestar emocional positivo, la persona mira hacia el pasado con satisfacción, orgullo y serenidad; al presente, con alegría, gozo, placer, satisfacción, y al futuro con optimismo, confianza y esperanza. Conlleva a una vida placentera, a veces con el uso de fortalezas para el logro. El significado de la vida involucra disfrutar de los momentos felices y también el hacer uso de las fortalezas para enfrentar una situación que podría rebasar los propios recursos. La importancia de dar soporte a los estudiantes tanto desde los vínculos motivadores y facilitadores como desde el hogar y las instituciones educativas podrá fortalecer en ellos la resiliencia para procurarse bienestar. El objetivo fue analizar las relaciones entre resiliencia con habilidades interpersonales, afrontamiento y estado emocional positivo, rendimiento académico y barreras en adolescentes, estudiantes de bachillerato.

PRE-SERVICE TEACHERS’ VIEWS ABOUT THEIR COMMUNICATIVE COMPETENCE: AN ANALYSIS OF ESL STUDENTS' GROUP ORAL PRESENTATIONS AT TUMU COLLEGE OF EDUCATION, GHANA
Authors: Wasila Mahamud , Owusu Sefa
Published: August 2024

Oral presentations are a major pedagogical activity recommended by the curriculum designers of the Bachelor of Education programme, which was implemented in 2018 in Ghana. In light of this, students are frequently called upon to work in groups and participate in oral group work. The study sought to find out the views of pre-service teachers of group oral presentations on their communicative competence and to assess the extent to which they exhibit communicative competence during group oral presentations. 112 third-year Bachelor of Education students at Tumu College of Education were purposively selected for the study. The questionnaire survey was responded to through Google Forms. The data was analyzed through SPSS, and the results were tabulated using percentages, mean and standard deviation. The study findings revealed that the group oral presentations created anxiety for students, though they proved to positively impact their language skills. Based on the students’ general acknowledgement of its positive impact they strongly endorsed the presentations as an important tool for language learning. The study further indicated that the students had knowledge of communicative competence as they rated themselves high in most competencies except a few areas, such as lack of confidence and not considering the socio-cultural background of colleagues during group presentations, among others. Hence, they needed more interactive instructional strategies that could help them boost their communicative competence.

THE WASHBACK EFFECT OF THE MOROCCAN ENGLISH BACCALAUREATE EXAMINATION ON TEACHING PRACTICES
Authors: El Ourf Mounir , Marjane Driss
Published: August 2024

This study investigated the possible influence of the Moroccan English baccalaureate examination on what and how teachers teach in class. This study was carried out in the city of Fes, Morocco, where classroom observations were conducted in three high schools. These were followed by post-observation interviews and a structured questionnaire. The findings indicated that teachers’ choice of teaching materials, the content of their course, and their teaching methodology were affected by the examination. However, the teachers in the study revealed that they were subjected to different degrees of influence. Some teachers thought that it was necessary to adopt exam-oriented activities to meet the demands of the examinations, whereas others were aware of the limitations associated with concentrating on examination preparation and thus were not affected by it to a great extent. Based on those results, it was recommended that any reform of teaching materials or teaching methodology has to go hand in hand with a reform of the format and content of the English baccalaureate examination.

THE EFFECT OF PERFORMANCE ASSESSMENT APPROACH ON THE DEVELOPMENT OF READING COMPREHENSION SKILLS IN ENGLISH FOR SPECIFIC PURPOSES CONTEXT
Authors: Boubekri Abdelhakim , Rouijel El Hassan
Published: August 2024

Reading comprehension is a crucial component of academic development for students engaged in English for Specific Purposes (ESP). This study investigates the efficacy of alternative assessment methods, specifically performance assessment, in enhancing reading comprehension skills within the ESP context. Given that reading comprehension is a fundamental input skill, deficiencies in this area can significantly impede academic progress. The research employed a pre-test and post-test experimental design with a control group to evaluate the impact of performance assessment on reading comprehension. Participants, after a proficiency test, were randomly assigned to either a control group or an experimental group, each of comparable proficiency levels. The experimental group received continuous assessment and immediate, relevant feedback during the training, while the control group did not receive such assessment or feedback. The experimental group's assessment was facilitated through a detailed assessment grid. Data were collected through pre-tests and post-tests administered to both groups and analyzed using SPSS (2018). Statistical analyses, including paired samples t-tests and independent samples t-tests, were conducted to measure intra-group progress and inter-group differences. Findings indicate that both groups showed significant improvement in reading comprehension; however, the experimental group exhibited superior performance across all comprehension categories compared to the control group. The results underscore the effectiveness of performance assessment in fostering both higher-order and lower-order reading comprehension skills, suggesting a pronounced advantage over traditional assessment methods. The study affirms the value of performance assessment in ESP contexts while also acknowledging the continued relevance of traditional assessment techniques.

STRATEGIES IN ORAL ENGLISH INSTRUCTION: A PEDAGOGICAL STUDY OF SOME GHANAIAN SENIOR HIGH SCHOOLS
Authors: Gyasi Emmanuel Appiah , Owusu Sefa
Published: August 2024

Research on English language instruction, particularly on oral English, is increasingly growing in Ghana and in many countries where the English language is not only used as an official language but also as a language for the medium of instruction and a subject of study in schools. This can perhaps be attributed to the global demand for and use of the English language despite the many difficulties in its instruction. The current study investigates the instructional strategies teachers of English in selected senior high schools in Ghana employ during oral English instruction. Utilizing a mixed-method approach with a convergent parallel design, the study collected data through questionnaires, interviews, and classroom observations involving 43 English teachers from five senior high schools. The findings reveal a predominant reliance on traditional and direct instructional strategies such as question-and-answer sessions and drills in lieu of more interactive and indirect methods like paired conversations, oral reports, debates, etc. Meanwhile, teachers attribute their instructional choices to large class sizes, teaching environment, instructional resources and the teacher’s pedagogical skills. Based on these findings, The study concludes by advocating for the integration of a diverse range of instructional strategies, especially interactive and experiential strategies, to enhance student engagement and improve oral language competencies both inside and outside the classroom.

ASSESSING THE REPERCUSSIONS OF DICTIONARY FORMATS ON SCHOLARLY WRITING OUTCOMES: UNDERTAKING MIXED-METHOD APPROACH
Authors: Wei Li-Wei
Published: August 2024

The complexity of foreign vocabulary and the multifaceted meanings of word combinations often pose significant challenges to language learners, potentially deterring their motivation. Dictionaries, however, serve as pivotal tools in surmounting these obstacles. Extant research has extensively explored the intersection of language acquisition and dictionary utilization, revealing a marked preference among EFL students for online or electronic dictionaries over traditional paper formats. Despite the recognized importance of dictionary use in fostering language proficiency, there remains a notable paucity of research investigating the specific impact of different dictionary formats on learners' writing skills. This study adopted a quasi-experimental between-groups design, including a control group and two experimental groups, involving a cohort of 67 Chinese EFL graduates from an international college in China. Over a ten-week experimental period, participants in the experimental groups utilized digital and paper dictionaries as reference aids for abstract writing, whereas the control group was deprived of any dictionary usage. Following the experiment, a semi-structured interview was conducted to assess the benefits of dictionary use in abstract writing and to elicit learners' perceptions of digital versus print English dictionaries. The weekly abstract writing submissions from all three groups were collected and meticulously analyzed. The findings revealed that both digital and paper dictionaries significantly enhanced the abstract writing performance of the Chinese EFL graduates in the experimental groups. Notably, participants who used digital dictionaries demonstrated a substantial and statistically significant improvement in overall abstract writing quality and language usage compared to those in the print-dictionary group. Furthermore, the study reported that digital dictionaries were particularly favored by Chinese EFL graduates due to their numerous advantageous attributes, including their reliability and efficacy in identifying appropriate linguistic expressions and vocabulary. In conclusion, the empirical evidence underscores the efficacy of digital dictionaries in augmenting the writing skills of EFL learners, suggesting a potential pedagogical shift towards the integration of digital lexicographical resources in language education curricula.

The present work deals with the pedagogical coordinator in democratic school management. Democratic school management originated in the 1970s and 1980s, when the state decentralized its power. It is important that this management occurs, so that the elements involved feel part of the decision-making processes and solutions of problems, exercising democracy in search of the collective benefit. The pedagogical coordinator plays a fundamental role in this type of management, not being a leader or an authority, but an articulating leader, who harmonizes the relationships between school, student, teacher, director, community, parents and others involved, always giving priority to the pedagogical proposal decided by team and the qualification of the learning teaching process.
SEDATION AND LARYNGOSPASM IN PEDIATRIC SURGERY
Authors: Alves Bezerra Bezerra Rebeca , Ester Silva Damasceno Jullyanne , Ferreira de Farias Natália , Da Nóbrega Dias Milena
Published: August 2024

Introduction: The use of anesthetics in pediatrics is essential for diagnostic and therapeutic procedures. The incidence of post-anesthetic respiratory complications is often avoidable with appropriate intervention. Laryngospasm, a reflex obstruction of the vocal cords, is more common in children. Objective: To discuss respiratory complications, with an emphasis on laryngospasm, during the use of anesthetics in pediatric procedures. Method: The Medical Literature Analysis and Retrieval System Online (MEDLINE, via PUBMED), Latin American and Caribbean Health Sciences Literature (LILACS), Scientific Electronic Library Online (SciELO), and Virtual Health Library (VHL) databases were used. Seven articles were selected that met the systematic review criteria. Results: The incidence of laryngospasm is 0.87% in adults, 1.7% in children, and 2.82% in babies. In children, it occurs mainly during emergence from anesthesia. Risk factors include inadequate anesthesia, respiratory infections and multiple attempts at airway management. Drug combinations such as propofol, ketamine and fentanyl are used to minimize complications. Preventive measures include clearing secretions and adequate depth of anesthesia. Drugs such β2-adrenergic agonists, such as albuterol, are used to reduce respiratory resistance during intubation. Training strategies with low-cost simulators are effective for managing difficult airways in pediatrics. In pediatric surgery, the laryngeal mask is preferred to endotracheal intubation to reduce respiratory complications. Studies indicate that positive communication between anesthesia teams improves performance in critical situations. Conclusion: Laryngospasm is a serious complication in pediatric anesthesia, more common in children due to their anatomy and sensitive reflexes. Risk factors include respiratory infections, asthma, smoking, gastroesophageal reflux, and superficial anesthesia. Prevention involves the proper use of anesthetics, cleaning secretions and careful monitoring. Medications such as propofol, ketamine, and albuterol can reduce adverse effects. Simulator training and effective communication in anesthesia teams improve clinical performance. With proper management, most episodes are resolved without long-term complications.

Authors: Borisenko Aleksander , Uzakov Yassin , Greseva Ekaterina , Razinkova Victoria , Borisenko Aleksey
Published: August 2024

ABSTRACT
The problem of providing the population with a full-fledged balanced diet is currently quite acute worldwide. Therefore, one of the main tasks is to expand the range of fortified and functional food products, including those with prebiotic effects. The article presents the results of developing fortified boiled sausages, liver pates, and chopped semi-finished products, which have high consumer properties, nutritional and biological value, organoleptic characteristics, and a balanced nutritional composition. The minimum amino acid score value for the proposed boiled sausages is 95.6%, and, for liver pate – 99.6%, for chopped semi-finished products – 88.1%. The biological value of the protein of the developed products reaches 92.8%, 87.7%, and 99.7%, respectively. This is achieved through specially selected components of animal and vegetable origin. Meat and meat-plant products were developed based on an analysis of the nutritional status of North Caucasus Federal University students. The optimal formulation was determined, and the nutrient balance of the finished products was ensured using computer modelling. Using dry milk molasses with lactulose "LactuVet-1" in the formulations of fortified meat products made it possible to increase their organoleptic characteristics and enrich them with calcium (about 150 mg per 100 g of finished product) and other minerals. The developed meat products contain lactulose, g/100 g of product: boiled sausages – 0.46, chopped semi-finished products – 0.61, liver pate – 0.76. This helped to ensure the prebiotic effect of the finished product. The proposed meat products are a source of vitamin A and calcium, contain most B vitamins, macroelements potassium and magnesium, and microelements iron and zinc. The complex of tasks to reduce the deficit of the main types of nutrients, revealed during the study, can be solved by including the developed meat products in the diet of the target group of consumers.

A method for determining polychlorinated biphenyls (PCBs) in fish roe by gas chromatography (GC) has been developed. The suitability (validation) of the process for the determination of 14 PCBs (PCB 18, PCB 31, PCB 28, PCB 52, PCB 44, PCB 101, PCB 149, PCB 118, PCB 153, PCB 138, PCB 180, PCB 170, PCB 194, PCB 209) in fish roe by GC using an electron capture detector (ECD) was evaluated according to the following criteria: selectivity, linearity, limits of detection (LOD), limits of quantification (LOQ), accuracy and precision. Automated Soxhlet extraction and sample clean-up by solid phase extraction (SPE) were proposed for extracting PCBs from fish roe. The results of the method selectivity study showed that the determination of PCBs in fish roe is not affected by other components in the sample. The correlation coefficients for fourteen PCBs ranged from 0.9962 to 0.9999 (R2 ≥0.995). The limits of detection (LOD) and limits of quantification (LOQ) of PCBs are below the maximum permissible levels set by the European Union (EU). The recovery percentage ranged from 81.5% to 107%, indicating the PCB extraction procedure's acceptability (R, 80 – 120%). The relative standard deviation (RSD, %) of the measurement results under convergence conditions ranged from 1.02% to 9.43% (RSD ≥15%). The obtained method suitability (validation) data meets the Commission Regulation (EU) No 589/2014 criteria.

Currently, about 5% of the earth's population suffers from gluten-related disorders. Modern technologies for gluten-free diets and filling the protein deficit are aimed at manufacturing gluten-free (GF) pasta products using non-conventional plant raw materials with high biological value. GF grains and crops (rice, corn, buckwheat, amaranth, quinoa, etc.) are used to produce GF pasta products. However, there is a scarcity of studies that comprehensively understand GF flour addition on the nutritive, sensory and cooking properties. Therefore, the scope of this literature review covers the main types of non-conventional raw materials for GF pasta products and summarizes the research on pasta products made from them. Results indicate that the rheological and sensory attributes of pasta made from pure GF flours such as rice or corn still requires a deeper study of technological processes in producing GF pasta. Incorporating nutrient-dense ingredients such as amaranth, quinoa, sorghum, and chia flours not only enhances the nutritional profile of gluten-free pasta but also offers opportunities for diverse culinary applications. The improvement of sensory attributes in rice-, corn-, buckwheat-based pasta, coupled with the effective use of cooking enhancers like xanthan gum, transglutaminases, inulin, and alternative starches, paves the way for creating more palatable gluten-free options. As techniques such as high-temperature treatment, extrusion cooking, and starch pregelatinization become more refined, future developments may focus on optimizing these processes to further improve the texture, taste, and overall quality of gluten-free pasta. Continued research and innovation in ingredient selection and processing technologies will be crucial for meeting the growing demand for gluten-free products that do not compromise on culinary experience or nutritional value.

The article is devoted to the influence of natural antioxidants on the quality parameters of meat semi-finished products from horse meat and the microbiological stability of the product during its storage. In solving the set tasks, the standard, generally accepted methods of research were used. Statistical processing of the obtained results and assessment of data reliability were carried out by statistical methods using Microsoft Excel and Statistica (version 12.0). A new antioxidant of natural origin, dihydroquercetin, has been proposed and tested. Effective doses of its application have been established: 0.05 - 0.075% for raw horse fat and 0.075% for semi-finished meat products from horse meat produced with its addition. It has been shown that the administration of dihydroquercetin (Dx) together with ascorbic acid (AA) and tocopherol (Tp) is 10-30% more effective. The effect of dihydroquercetin on the indicators of oxidative spoilage in the technological process, from the production of horse meat to finished products using the latter, has been studied. The organoleptic parameters (appearance, odour, colour) of the control sample and the sample with 0.025% Dx by fat weight corresponded in their characteristics to the experimental samples with 0.05%, 0.075% and 0.1% by 45 days of storage. The introduction of dihydroquercetin, ascorbic acid, and tocopherol also makes it possible to slow down the microbiological spoilage of the semi-finished products that have been obtained during storage.

Research on the nutritional content of wild plant fruits in Kazakhstan, including Hawthorn fruit (Crataegus laevigata), rosehip fruit (Rose canina L. variety), sea buckthorn fruit (Hippophae rhamnoides - Altai variety), and black chokeberry fruit (Aronia melanocarpa), has determined that these fruits possess a combination of properties essential for maintaining human health, attributed to the presence of bioactive substances (BAS) and other components.  The technological process for obtaining extracts and concentrates from wild-growing raw material fruit has developed. The following extraction modes were proposed: ultrasonic wave frequency 40 kHz, extraction time 30 minutes, temperature 500С, and concentration of the obtained extracts was carried out by vacuum evaporation method, using IKA RV-10 apparatus at 40-50°С and pressure 800 mbar. Found that extracts and concentrates have a higher concentration of nutritional substances when compared to the fruits themselves.  Thus, the vitamin C content in hawthorn fruits was 27.8 mg, while in the extract, it was 47.84 mg, and in the concentrate – 62.19 mg. The vitamin C content in rosehip fruits, extracts, and concentrates was 578.01 mg, 811.8 mg, and 1101.3 mg, respectively. The vitamin C content in sea buckthorn fruits, extracts, and concentrates was 285.05 mg, 518.8 mg, and 640.9 mg, respectively. The vitamin C content in black chokeberry fruits, extracts, and concentrates was 86.2 mg, 128.8 mg, and 160.5 mg, respectively. A similar increase was observed for the content of vitamin E and other components. Furthermore, the obtained concentrates meet the safety parameters required by regulatory documents. A technology for producing grain crispbread using the extrusion method has developed, incorporating whole grains, groats, flavouring additives, and concentrates derived from wild fruits such as hawthorn, rosehip, sea buckthorn, and black chokeberry into the recipe.
