Relevância e Factibilidade do Envolvimento das Mulheres na Promoção da Produção e da Segurança Alimentar no Sul da África
Authors: Assan Never
Published: September 2022

Harnessing women’s potential for food production and security has been a challenge in Southern Africa. The face of food production in Southern Africa is often female, but more often than not, their roles are generally undervalued and constrained by gender inequalities and limitations on their access to resources, services, and market opportunities. This chapter explores how women involvement in food production can have a positive impact on food security in Southern Africa. The gender aspect of food security assume significance, as it is widely recognized that women are the custodian of food production in many communities in Southern Africa. There is a tendency of men and women participating unevenly in food production, have unequal access to productive resources and exhibit different levels of engagement in rural, urban and home-based food production. Despite this anomaly, there is still a common understanding that food production needs to be increased in order to cope with the increased human population and achieving food security in the region. With this in mind, food production and security have emerged as key development targets in Southern Africa. This has propelled the urgent need for promoting food production, reducing food insecurity and poverty reduction in its totality. One of the factors contributing to perpetual low food production and insecurity has been gender discrimination and/or lack of participation of women in agricultural programs and projects. In this chapter there is an attempt to describe the impact of gender-based discrimination on food production and its implication on food security. The indispensable role and challenges faced by women in food production are highlighted. The need to invest in education and training of women to support food production systems in order to accrue maximum benefit is acknowledged. In this regard, it is imperative that planning and implementation of any food production programs focusing on improving food security should be based on gender sensitive policies. Policies which give women due recognition as far as food production decision making processes are concerned are sought. The chapter concludes with the understanding that involvement of women in food production becomes a key component of addressing food insecurity in Southern Africa. The vulnerability of people in Southern Africa to food insecurity depends both on measures that can be implemented in a given context and the capacity of families, and women in particular, to respond to food shortages. It is important, therefore that food security remains high on the regional development agenda. The region should prioritize appropriate interventions which help women fully participate in food production and develop sustainable livelihoods.

Modifiable nutritional factors in hyperuricemia and gout
Authors: Georginova Olga A. , Astashkevich Polina N. , Krasnova Tatyana N.
Published: September 2022

Uric acid is an independent risk factor for socially important diseases, such as chronic heart failure and chronic kidney disease. The review summarizes current data on the impact of nutrition as a presumably modifiable factor into the development of hyperuricemia and gout. The authors describe biochemical mechanisms underlying hyperuricemia and present data on the influence of excessive intake of fructose, purines, and various alcohol-containing drinks on the risk of gout. Favorable impact of vitamin C supplements, coffee, cherry juice, some chemical elements (magnesium, zinc, and copper) on uric acid levels has been shown, as well as the impact of intake of low fat dairy products, polyphenols, food fibers, and omega-3 polyunsaturated fatty acids on the incidence of hyperuricemia. The information presented in the review can be used in clinical practice for preparation of an individualized nutritional plan aimed at normalization of uric acid levels. This would minimize the use of agents affecting the synthesis of uric acid and slow down the progression of chronic heart failure and chronic kidney disease.
Psychological symptoms in children who are victims of war and migration: Comparison of Turkish and Syrian students
Authors: Çekiç Ali
Published: September 2022

The aim of this study is to examine whether exposure to war and migration trauma has a long-term effect on psychological symptoms in children. The Brief Symptom Inventory was administered to a total of 207 students, 111 of whom were Syrians and 96 of whom were Turks, studying at a secondary school in the Mamak district of Ankara. The data obtained show that Syrian students have higher average scores in the anxiety, negative self and somatisation sub-dimensions than their Turkish peers. This situation can be considered an important indicator as war and forced migration caused by war negatively affect children’s mental health. As a matter of fact, the effects of post-traumatic mental health disorders in children who have experienced war trauma can be seen even 5 years after the traumatic event. Syrian students whose mental health was evaluated within the scope of this research have been living in Turkey for 4–6 years.

Mujeres empresarias colombianas
Authors: Berdugo Cotera Elber Enrique
Published: September 2022

A través de la historia, las mujeres han sido relegadas a un segundo plano e invisibilizadas. El Estado y la sociedad las han visto únicamente como reproductoras y proveedoras sexuales, responsables de los oficios del hogar y la crianza de los hijos, pese al papel que han desempeñando, en distintos roles, a la par con los hombres. Han sobresalido en diversos campos (científico, cultural y político) y ocupado altos cargos, tanto en organizaciones públicas como privadas. También, han participado activamente en los sectores económicos (primario, secundario y terciario), como empleadas en niveles inferiores o mediante sus emprendimientos empresariales, con lo cual han contribuido a la generación de riqueza y bienestar a la sociedad. Los aportes de las mujeres al desarrollo de los países son significativos: en el ámbito internacional, han fundado y son propietarias, sobre todo, de empresas micro, pequeñas y medianas, aunque también de grandes, como lo demuestran diferentes investigaciones y publicaciones, aun cuando falta documentar más sobre su papel de empresarias.

Este libro nace con el objetivo de acercar al lector a nuevos temas de investigación aplicada en la empresa familiar que ha de sobrevivir en entornos competitivos a escala global. Con la excepción de los microemprendedores, especialmente aquellos cuyos micronegocios nacen por la necesidad de supervivencia, tanto la pequeña y la mediana empresa (pyrne) como las empresas transnacionales y multinacionales actúan en entornos basados en la glocalidad (piensa globalmente, actúa localmente), de forma que solamente sobreviven aquellas empresas que han sabido aprovechar de forma eficiente sus oportunidades de negocio. Para la realización de este libro, hemos invitado a docentes, investigadores y consultores especializados en empresa familiar en España, Colombia y Brasil para así tener una visión transatlántica del tema. La edición del libro en español y portugués proporciona una visión internacional del contexto en que la empresa familiar se encuentra inmersa en la vorágine de una globalización económica impulsada por las tecnologías de la información y la comunicación (TIC) que han cambiado nuestras vidas.
Gestión humana en la empresa colombiana
Authors: Díaz Vargas Esperanza , Rodríguez Restrepo Víctor José
Published: September 2022

Todas las personas están en capacidad de trabajar mancomunadamente; sin embargo, es necesario conocer las diferentes técnicas y los avances generados en los últimos años en materia de talento humano, con el fin de alcanzar un buen grado de satisfacción y desarrollo profesional y personal. Las empresas, en particular las colombianas, apenas están reconociendo la importancia del trato con sus colaboradores para generar una cultura organizacional responsable. Después de trabajar varios cursos de esta asignatura en el transcurso de los años, se ha elaborado un documento denominado Gestión humana en la empresa colombiana, el cual contiene puntos esenciales de la gerencia de personal para que los estudiantes se apropien de este conocimiento y no cometan errores muy recurrentes en el trato continuo con la gente en las empresas, al desarrollar actividades de manejo, coordinación y ubicación del personal. Este libro pretende establecer una diferencia entre administrar personal y gestionar talentos: ¿cómo desarrollar las habilidades de la gente para mostrar y emplear ese potencial en puestos determinantes de la tarea empresarial? ¿Cómo hacer uso de las técnicas empleadas por varios autores especialistas en materia del análisis ocupacional, en la actividad por procesos diversos, existentes en las empresas hasta llegar a lo más innovador del desarrollo operativo de las personas, llamado lo polifuncional?

Humanitarian Considerations in Disarmament, Demobilisation and Reintegration (DDR)
Authors: Kelly Luke
Published: September 2022

This rapid literature review finds that disarmament, demobilisation and reintegration (DDR) raises a number of humanitarian considerations, centred on the treatment of participants and the unintended consequences of the programmes. In particular, DDR undertaken during conflicts is linked to several protection risks and is difficult to implement in a neutral, equitable and humanitarian manner. By humanitarian concerns, this report means: • Some of the functions undertaken in DDR, • Humanitarian risks to individuals in DDR programmes, • Indirect risks of conflict arising from DDR programmes; DDR is a broad and multi-faceted process involving security, humanitarian and development aspects and actors, with wide-ranging impacts. Humanitarian actors do not undertake DDR, but they may support some DDR processes, and maybe affected by DDR or its effects. According to UN guidance and the academic literature, successful DDR will consider socio-economic conditions in the community, as well as for the ex-combatants. It should be attuned to the range of needs of participants and should abide by relevant international law. The political dynamics of a conflict or post-conflict situation shape the success of DDR. It was first used in post-conflict situations, but the increasing use of DDR in ongoing conflicts creates new difficulties. The failure or partial implementation creates many humanitarian problems. This may arise from a lack of resources; competing authorities (and particularly the co-option of DDR for war aims); ongoing conflict and instability; mistakes in implementation; and socio-economic conditions unconducive to successful reintegration. Unsuccessful DDR may see partially demobilised actors remain dangerous, or may fuel new grievances around the perceived unfairness of granting support to former combatants. There is a large body of evidence on the successes and failures of DDR programmes, how they vary over time and across contexts, and guidance on how to implement DDR. Relatively little refers explicitly to humanitarian concerns, but many of the issues covered can be characterised as humanitarian. DDR has been employed in many situations since the 1980s, meaning that it is not possible to comprehensively survey the guidance or case study evidence. Instead, this review focuses on the main areas where DDR can be said to raise humanitarian concerns, with a particular focus on the problems raised by DDR in ongoing conflicts.

A Educação Profissional na Rede Estadual de Educação do Rio Grande do Norte: da Lei nº 5.692/1971 ao Programa Brasil Profissionalizado
Authors: Silva José Moisés Nunes da , Nascimento Suerda Maria Nogueira do , Freitas José Flavio de
Published: September 2022

The text presents a reflection about the professional education in the State Education Network of Rio Grande do Norte. The objective is to analyze the offer of this kind of education, since Law number 5.692/1971 since the Professionalized Brazil Program (PBP), in order to consider the development of professional education in the mentioned Network. Methodologically, the research is qualitative, supported by bibliographic research (authors who discuss the theme) and documentary research (laws, decrees, resolutions, reports etc.), having dialectics as the main thread of analysis. The offer of professional education was historicized in the light of the Law number 5.692/1971 and the Law number 9.394/1996 in the State Education Network of Rio Grande do Norte, identifying its specificities. Additionally, we discussed the contribution of the PBP as an inducer of the expansion of enrollment in professional education in the Network. The results point out that since the 1970s the state actions in the epistemic field have been timid; the PBP was decisive in the resumption and expansion of professional education in the Network; and that the State Government has been carrying out actions toward the implementation of a state professional education policy.
Institutos Federais de Educação, Ciência e Tecnologia: travessia para uma nova sociedade
Authors: Donadel Taigra Biasi , Rodrigues Ricardo Antonio , Castaman Ana Sara
Published: September 2022

This study has the purpose of discussing about science and technology, as prerogatives of the Federal Institutes of Education, Science and Technology (IF), to emphasize its responsibility in the integrated training of the students, and not to launch itself as a mere strategic arm of the market and capital. For that, it was guided in the bibliographic technique, from exploratory and descriptive objectives, privileging an approach of critical analysis of historical-dialectical matrix. It is divided into three parts: a) the methodological procedures are presented; b) it deals with science and technology as elements that need to be interconnected in the training of the subject at IF; c) it deals with the integrated training at IF. It appears that teaching in Professional and Technological Education requires clarification from those involved in the epistemic challenges of the scientific and technological knowledge production, as well as their role in building a solidary, free, fair, and democratic society, considering the integrated human training.

Authors: Macedo Laiz Mara Meneses , Cavalcante Ilane Ferreira , Frutuoso Camilla Munay Dantas
Published: September 2022

The present article evaluated the State of Knowledge of the concept of Integrative Pedagogical Practices. The purpose of this evaluation is to contribute to debates that connect to the perspective of praxis in Vocational and Technological Education. In view of the above, the following guiding question is established: How does the field of Integrative Pedagogical Practices present itself in the scientific and knowledge production? Methodologically, this research is classified as being of a basic nature, with a quali-quantitative approach, supported by the assumptions of the analyses of the "production of knowledge" type. This methodological delineation allowed the survey and mapping of data, as well as their categorization. The analysis made it possible to describe the conceptual trajectory of Integrative Pedagogical Practices in the scientific production and knowledge about the theme. The analysis indicated that the concept of Integrative Pedagogical Practices epistemologically connects to the concept of emancipatory praxis and consequently to the assumptions of integrated human formation.
Comportamento autolesivo e ideação suicida na Adolescência: desafios na Educação Profissional e Tecnológica
Authors: Barbosa Xênia de Castro , Oliveira Rodrigo Leonardo de Sousa
Published: September 2022

This article aims to communicate the results of the research entitled “Pedagogy of presence applied to the prevention of suicidal ideation and self-harm in adolescence”, developed at the Federal Institute of Rondônia. The objectives of the study were to contribute to the pedagogical management of the problem of suicidal ideation and self-harming behavior in adolescents, through theoretical reflection and transfer of two educational products. The research was developed in a qualitative approach, based on the Educational Action Research methodology. The results indicate that the school is both a factor of stress and illness and it has the potential to contribute to the promotion of students' mental health, self-care and care for others. It is argued that an omnilateral training, supported by the Pedagogy of Presence is capable of favoring the understanding of the structural and conjunctural factors of our time - which favors the reduction of personal frustrations, the flexibilization of the notions of failure and success among adolescents, and the development of cognitive and socio-emotional skills, in addition to what has been stimulated by neoliberal education reforms.
Saberes e disposições para a docência: um estudo com professores de Libras do ensino superior
Authors: Corrêa Lucinara Bastiani , Brancher Vantoir Roberto , Bortolin Luana Cassol
Published: September 2022

This article aims to get to know the teaching knowledge that is mobilized by Libras (Brazilian Sign Language) teachers in Higher Education. The profession of Libras teachers is relatively recent, and it came into existence in Brazil with the officialization of Libras as a language of communication and expression for Brazilian deaf people according to Law 10436/2002. Thus, researching teaching knowledge becomes important in qualifying the training of Libras teachers. Through a qualitative methodology it was possible to interview six Libras teachers working in Higher Education. The interviews were categorized by content analysis (BARDIN, 2016) for further interpretation. Authors such as Nóvoa (2009), Tardif (2014), and Cunha (2010) theoretically referred to the discussions about teaching in Libras. As a result, the data showed the different origins of this knowledge which have been established since entering school as students and developing throughout life. Furthermore, it indicated the temporality of training and professional development, as a continuous process, and the importance of collective work and the exchanges between peers as a device of significant training.
The characteristic of follower’s personal mastery: A case in Indonesian construction industry
Authors: Soeprapto Dedy Dewanto
Published: September 2022

The purpose of this study is to understand the characteristics of Follower's Personal Mastery in the construction industry where followers are the givers of ideas and knowledge. We recognize the construction industry as one of the project-based organizations, has stiff competition criteria and the need for innovation in a short time span, so this research is very important because innovation results from the exchange of ideas and knowledge between leaders and followers ( Nahapiet & Ghoshal, 1998) through the Leader-member Exchange (LMX) mechanism (Dewanto, 2013). Leaders are known to have comprehensive general knowledge, while followers are known to have deep specialized knowledge (Hobday, 2000; Dewanto, 2013). The higher the Follower's Personal Mastery level, the higher the quality of the exchange of ideas and knowledge that is exchanged between followers and leaders. We chose research conducted in a construction State-Owned Enterprise (BUMN) in Indonesia which has many branches throughout the region, so that it is able to represent the construction industry. This study involved all 121 projects spread across Indonesia that existed at the time of data collection. The analytical method used in this research is descriptive statistical analysis, and the participation rate is 97.52 percent. The findings show that Follower’s Personal Mastery Variables has a high level with a mean of 4.56, especially In-Process Behavior 4.77 and Output Behavior 4.73.

Published: September 2022

Childhood asthma is a chronic airway disease, which pathogenesis is markedly heterogeneous–with multiple phenotypes defining visible characteristics and endotypes defining molecular mechanisms. Cytokines and chemokines released during inflammatory responses are key immune mediators. The cytokine response can largely determine the susceptibility to childhood asthma and its severity. The purpose of this study was to characterize the immune profile of childhood asthma. The study involved 26 children (3–18 years old), who were divided into 2 groups: study–with childhood asthma; control–without asthma. The innovative Bio-Plex method was used to determine the serum concentration of 37 inflammatory proteins in one experiment. The results were analyzed using univariate statistical tests. In the study group, the level of the 10 tested markers increased, while the level of the remaining 9 decreased compared to the control; a statistically significant reduction in concentration was obtained only for the MMP-1(p<0.05). According to the ROC curve, MMP-1 can be considered an effective discriminator of childhood asthma (p<0.05; AUC=0.752). Cytokines/chemokines may be useful in the diagnosis of childhood asthma and may also become a prognostic target in determining the phenotype/endotype of this condition. This study should be a prelude to and an incentive for more complex proteomic analyzes.
All-Polymeric Electrode based on PEDOT:PSS for In-Vivo Neural Recording

Published: September 2022

One of the significant challenges today in the brain-machine interface using invasive methods is the stability of the chronic record. In recent years, polymer-based electrodes have gained notoriety for achieving mechanical strength values close to that of brain tissue, promoting a lower immune response to the implant. In this work, we fabricated fully polymeric electrodes based on PEDOT:PSS for neural recording in Wistar rats. We characterized the electrical properties and both in-vitro and in-vivo functionality of the electrodes. Also, we employed histological processing and microscopical visualization to evaluate tecidual immune response in 7, 14, and 21 days post-implant days. Electrodes with 400-micrometer channels showed a 12dB signal-to-noise ratio. Local field potentials were characterized under two conditions: anesthetized and free-moving. There was a proliferation of microglia to the tissue-electrode interface in the first days, with a decrease after 14 days. Astrocytes also migrated to the interface, but there was no continuous recruitment of these cells in the tissue, showing inflammatory stability at 21 days. The signal was not affected by this inflammatory action, demonstrating that fully polymeric electrodes can be an alternative to prolong the valuable time of neural recordings.
Contract Farming and Climate Change Adaptation in Rural Zimbabwe
Authors: Ndhlovu Emmanuel
Published: September 2022

The literature on contract farming and climate change in Zimbabwe has blind spots in relation to the study of contract farming as a climate change response. While the literature on contract farming and climate change abounds, such literature is lacking when it comes to the exploration of how contract farming can facilitate climate change coping and adaptation strategies by smallholder farmers. This paper fills this gap. It draws on in-depth interviews with 10 contracted and 10 non-contract farmers who were engaged through face-to-face in-depth interviews in the Chipinge South Constituency. It found that contract farming does not only boost productivity, but it also enables farmers to positively respond to the ravages of climate change, and therefore, it should be supported and encouraged. Future research should explore more viable and sustainable way through which the state, instead of private sector actors, should be at the centre of contract farming.
Quantum Mechanical Comparison between Lithiated and Sodiated Silicon Nanowires
Authors: Boone Donald
Published: September 2022

This computational research study will compare the specific charge capacity (SCC) between lithium ions inserted into crystallize silicon (c-Si) nanowires versus sodium ions inserted into amorphous silicon (a-Si) nanowires. It will be demonstrated that the potential energy V(r) within the lithium-silicon nanowire supports a coherent energy state model with discrete electron particles while the sodium-silicon nanowire potential energy will be discovered to be essentially zero and thus the electron current that travels through the sodiated silicon nanowire will be modeled as free electron with wave-like characteristics. This is due to the vast differences in the electric fields of the lithiated and sodiated silicon nanowires where the electric fields are of the order of 1e10 V/m and 1e-15 V/m respectively. The main reason for the great disparity in electric fields are due to the present of optical amplification within lithium ions and the absence of this process within sodium ions. It will be shown that optical amplification develops coherent optical interactions which is the primary reason for the surge of specific charge capacity in the lithiated silicon nanowire. Conversely, the lack of optical amplification is the reason for the incoherent optical interactions within sodium ions which is the reason for the low presence of SCC in sodiated silicon nanowires.

Published: September 2022

Aim. In the current study, we aimed at identifying resting-state brain networks, which are different in patients with depression compared to healthy individuals. Moreover, we analyzed the potential for clinical use of different network measures that could discriminate the two groups and thus help the diagnostic process. Method and subjects. We recruited 90 subjects: 49 healthy controls (HC) and 41 patients with a major depressive episode (MDE). All subjects underwent clinical evaluation and functional resting-state MRI. The data were processed to investigate functional connectivity network measures across the two groups using Brain Connectivity Toolbox. The statistical inferences were made at the functional networks level, using false discovery rate method. Independent samples t-test was performed on the network measures mean values to reveal differences between HC and MDE groups. Permutation-based statistical testing was used to test the significance of the difference between the distributions of the network measures by nodes for HC and MDE groups. Linear discriminant analysis was used to differentiate between the groups. Results and discussion. Significant differences in FC between depressed patients and healthy controls were found with the most prominent changes encompassing within-region as well as between-region connectivity of occipital lobe areas such as precuneus (PreCu), cuneus (Cu), superior occipital gyrus (SOG), lingual gyrus (LG), fusiform gyrus (FG), cerebellum, along with limbic structures including the hippocampus (Hipp) and cingulate gyrus. Linear discriminant analysis demonstrated that the full connectivity matrices, as well as those with only the significant connections identified in advance, were the most precise in differentiating between depression and health. These measures reached precision levels of 97% and 94%, respectively. Conclusion. Our study delivered further evidence about impairment of functional connectivity networks in MDE that may contribute to differentiate patients with depression from healthy subjects.
What is New in Prophylaxis and Treatment of Covid- 19 in Renal Transplant Patients?
Authors: Salvadori Maurizio
Published: September 2022

Abstract Kidney transplant recipients, because of a weak immune response due to the assumption of immunosuppressant are exposed to the risk of COVID-19 infection. This fact realize the problem on how to treat the severe infection without carrying the risk of acute rejection due to the reduction of the immunosuppressive drugs. The best are the prophylactic measures to be taken before transplantation as vaccination. If the patient is already transplanted, three measures may be undertaken: Vaccination, use of monoclonal antibodies, use of therapeutic antiviral small molecules. Concerning vaccination is still debated which one is the best and how many doses should be given. The surge of new virus variant is the major problem and invites to find new active vaccines. In addition, not all the transplanted patients develop antibodies. The other measure is the use of monoclonal antibodies. They may be used as prophylaxis or in the early stage of the disease. Finally, the antiviral small molecules may be used again as prophylaxis or treatment. Their major drawback are the interference with the immunosuppressive drugs and the fact that some of them cannot be administered to patients with low eGFR.

Latar Belakang: Peningkatan angka penderita sindrom metabolik secara global dianggap mengkhawatirkan karena mengakibatkan komplikasi masalah kesehatan pada berbagai organ termasuk organ reproduksi pria. Infertilitas pada pria yang disebabkan oleh inflamasi kronik dan kematian sel yang terjadi pada sindrom metabolik erat kaitannya dengan peran TNF-α sebagai mediator inflamasi. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ekstrak etanolik daun kelor terhadap ekspresi TNF-α pada jaringan testis tikus Wistar model sindrom metabolik.

Metode: Penelitian bersifat ekperimental laboratorik dengan rancangan penelitian posttest only control group design. Subjek tikus Wistar dibagi menjadi 5 kelompok dengan masing-masing kelompok berisi 6 tikus, KI sebagai kontrol normal, KII sebagai kelompok induksi sindrom metabolik, dan KIII, KIV, KV sebagai kelompok sindrom metabolik yang diberi ekstrak etanolik daun kelor dengan dosis secara berurutan 150 mg/kgBB, 250 mg/kgBB, dan 350 mg/kgBB. Induksi sindrom metabolik menggunakan pakan tinggi lemak dan STZ-NA. Perhitungan ekspresi TNF-α menggunakan metode semikuantitatif IDS. Analisis ekspresi TNF-α menggunakan uji One-Way ANOVA yang dilanjutkan post hoc LSD dan uji regresi linear.

Hasil: Uji One-Way ANOVA ekspresi TNF-α pada jaringan testis menunjukkan p=0,001 (p<0,05), maka terdapat perbedaan ekspresi TNF-α yang signifikan pada kelima kelompok. Perbedaan bermakna terdapat pada KI terhadap KII dan KII terhadap KIV dan KV. Uji regresi linear menunjukkan pengaruh dosis ekstrak etanolik daun kelor memberikan arah negatif terhadap ekspresi TNF-α.

Simpulan: Pemberian ekstrak etanolik daun kelor (Moringa oleifera, Lam) dengan dosis 150 mg/kgBB, 250 mg/kgBB, dan 350 mg/kgBB dapat menurunkan ekspresi TNF-α.

Electronic encumbrance Right is one of the breakthroughs made by the Minister of Agrarian Affairs to improve services in the land sector and support the Government in realizing a digital bureaucracy in Indonesia. This paper aims to deeply examine the validity and execution of such electronic Encumbrance Right Certificates.The main findings show that the electronic Encumbrance Right Certificate cannot be separated from the provisions of the Electronic Information and Transactions law, which lays out the conditions that must be met for the validity of electronic certificates and their status as evidence in court. The problem of authentication differs from the acknowledgement of electronic data. If the data or electronic documents are accepted or legally recognized, the authentication process for the data will automatically follow. The authentication process is a matter of technology while acknowledging electronic documents involves formal recognition in laws and regulations. Electronic evidence consisting of Electronic Information or Electronic Documents or the printouts produced by the Electronic System is legal evidence. On the other hand, if the Electronic Information is not generated through the Electronic System, the evidence cannot automatically be assessed as valid. Such electronic information can be used as electronic evidence if the authenticity, accuracy, and integrity have been verified through an information technology forensic audit

The subject of the article's research is the improvement of structural methods of image classification in computer vision systems. The goal is to reduce computational costs for classification by implementing a device for decomposing image description components using a system of orthogonal functions and implementing feature space compression models. Applied methods: ORB key point detector, set theory apparatus and vector spaces, metric models for determining relevance to sets of multidimensional vectors, theory of orthogonal decomposition of vectors, elements of probability theory, software modeling. Obtained results: modifications of the image classification method based on the introduction of orthogonal data decomposition in vector space were developed, models were proposed for data compression in the transformed feature space, Tanimoto metric was introduced for image comparison, a threshold selection method was established for determining equivalent description components. The effectiveness of the developed modifications of the classifier depends on the selection of a subset of functions for decomposition, the metric for comparing descriptions, and the method of determining the equivalence threshold. The implementation of the apparatus of orthogonal functions not only reduced computational costs tenfold, but also ensured sufficiently high indicators of classification performance and interference resistance. The practical significance of the work is the construction of new models of the image classifier in the transformed space of features, confirmation of the functionality, speed and immunity of the proposed modifications on examples of images, the creation of a software application for the implementation of the developed classification methods in computer vision systems.
EFFECT OF AMBIENT TEMPERATURE ON THERMODYNAMIC TEMPERATURE MEASUREMENTS

The development of science and technology is closely related to the use of measuring instruments. Measurements are one of the ways to know nature as a process and help to make scientific discoveries and apply these discoveries in production and technology. Measurements are also of great importance as the only means of monitoring technological processes in various fields of industry and production processes. Properly organized measurements ensure the reliability, economy and convenience of conducting production processes, as well as provide opportunities for their extensive automation. In addition, it is not possible to provide safe and trouble-free maintenance of production processes and facilities without using measurement tools. Today, the national economy of the country is provided with a large arsenal of measuring instruments of both domestic and foreign production, from the simplest primary converters and measuring devices to complex automatic tools and systems that allow controlling technological devices and complex production using information and computers. A wide variety of measuring tools requires the right choice for specific purposes. In this regard, one of the important issues is the question of their metrological assurance. Accurate and correct measurements performed during technological processes lead to an increase in product quality, a reduction in waste products, as well as a minimization of time and material losses. For this reason, ensuring the accuracy of temperature measurements performed in technological processes is one of the most urgent issues today. The research work has shown that the most important part of the error of the temperature measurements is the influence of the environment on the measurement process. For this reason, the amount of this effect was determined and analyzed during the research work.
