The theoretical basis of acupuncture and moxibustion in traditional Chinese medicine is recognized as "dredging meridians, promoting blood circulation, and removing blood stasis". In modern medical theories, the mechanism of acupuncture and moxibustion is discussed as "analgesia, improving the microenvironment, influencing hormone release and inflammatory mechanism". Many studies have confirmed its healing effects and established it as an effective method for treating sports medicine conditions. The application of acupuncture and moxibustion in the treatment of sports medicine conditions, such as tendinopathy, myofasciitis, ligament injury, peripheral nerve injury, tendon and bone healing, has been analyzed to understand its clinical efficacy and mechanism. Although acupuncture and moxibustion are widely used in sports medicine conditions, most of the current studies are retrospective and lack randomized double-blind controlled trials. Future research should include more randomized double-blind trials, using multi-center and large sample clinical observation, to further confirm the efficacy of acupuncture and moxibustion in the treatment of sports medicine disorders and improve its clinical application.

Algorithmic Governance, Public Participation and Trust
Authors: Bruun Maja Hojer
Published: January 2025

Two intertwined trends have hit cities all over the world: an increasing drive towards experimentation with citizens as participants that is turning cities into ‘living labs’ or ‘test-beds’, and the use of streams of digital data from people and devices for the algorithmic management of urban life following the ‘smart city’ model. In the visions of smart city designers and developers of data systems, public participation is configured as a matter of motivation and trust and how citizens can be persuaded to contribute their data through processes such as gamification. In this context, technomoral politics become a matter of engaging citizens in allegedly neutral data systems that are supposed to govern social and political processes. Yet, based on ethnographic work with citizens and officials who manage everyday life with floodings in Vejle, Denmark, this article demonstrates that the visions for technomoral participation tied to a smart city project can be challenged by alternative ways of participating through everyday acts of mutual investment and care, including also alternative uses of and experimentation with data.

Deux tendances interdépendantes ont impacté des villes à travers le monde : une campagne croissante pour des projets participatifs et expérimentaux qui permettent les citoyens de transformer des villes en ‘laboratoires vivantes’ ou ‘lits d'essai’, et l'utilisation de données générées pendant le streaming numérique pour la gestion de la vie urbaine fondée sur le modèle de la ville connectée. Pour les designers de la ville connectée et les développeurs de systèmes de données, la participation publique est configurée comme une question de motivation et de confiance. Elle montre comment les citoyens pourraient être persuadés à contribuer leurs données au travers des processus comme la prolifération des jeux. Dans ce contexte, la politique techno-morale devient une façon d'engager des citoyens dans les soi-disant systèmes de données neutres qui doivent gouverner des processus sociaux et politiques. Cet article s'appuie sur la recherche ethnographique avec les citoyens et les fonctionnaires qui gèrent des situations d'inondation à Vejle au Danemark. Nous montrons que les visions pour une participation techno-morale liée à un projet de ville connectée se sont heurtées contre les manières alternatives de participer au travers des actes journaliers d'investissement mutuelle et de soutien, qui utilisent elles-mêmes des stratégies alternatives pour expérimenter avec des données numériques.

Comparison of HTTP 2 Header Compression Methods
Authors:   Central Ukrainian National Technical University, Ulichev Olexandr , Revniuk Olexandr ,   Central Ukrainian National Technical University
Published: January 2025

The primary aim of this research is to analyze the key methods of header compression in the HTTP 2 protocol to optimize data transmission over the network. This study explores the prerequisites for developing the HPACK compression algorithm, assesses the potential threats and data loss risks associated with compression, and identifies strategies to minimize these risks. Additionally, the research focuses on the challenges of handling cookies in HTTP headers and determining optimal compression methods for reducing the volume of transmitted data, with practical examples from commercial code.
Introduced in 2015, HTTP 2 significantly improves web communication efficiency by utilizing multiplexing and header compression. Unlike HTTP 1.1, which involves repetitive transmission of headers for each request, HTTP 2 addresses this redundancy through HPACK, which uses static and dynamic header tables alongside Huffman coding. These techniques substantially reduce the data volume transmitted between client and server, lowering the load on network resources, especially in mobile environments with limited bandwidth. This paper examines how HPACK achieves data optimization by compressing frequently used headers while maintaining secure data transmission. It also explores various methods of implementing compression, including Huffman coding and lookup tables, to enhance efficiency in practical web applications. The findings highlight the trade-offs between compression efficiency and security, especially concerning the transmission of sensitive information like cookies.
The use of HPACK for header compression in HTTP 2 drastically reduces the volume of transmitted data, thereby improving network request efficiency. While Huffman coding is often effective, its benefits may not always outweigh those of traditional ASCII encoding, particularly for larger or less frequently used headers. The study concludes that effective compression strategies must consider both data optimization and security, especially when transmitting sensitive information such as cookies. By selecting the appropriate compression methods, it is possible to balance the efficiency of data transfer with the protection of confidential information. Future research should focus on enhancing HPACK's balance between compression and security as technologies evolve and potential vulnerabilities emerge.

It is shown that traditional models of ensuring information security, based on the security perimeter, do not allow to provide the required level of protection against possible threats.
ADNR is a defined set of management principles for the organization of activities that should be used in order to improve the information security of enterprises and increase the level of their security.
The main task of ADNR is to minimize information security risks from the impact of external intrusions by intruders on the company's information assets and ensure its normal functioning.
With the development of network technologies and the emergence of the possibility of remote work, there was a need to provide employees with secure access from their home computers to information services and corporate databases of enterprises. As a result, the architecture of information systems and security systems became more complicated. With the development of network technologies and the emergence of the possibility of remote work, there was a need to provide employees with secure access from their home computers to information services and corporate databases of enterprises. The result was the complication of information systems and security systems of enterprises.
When using the ADNR model, it is assumed that the attacker, who is most often from the outside, can also be inside the enterprise, and there is no difference between them. Based on this, when using the ADNR model, the company must abandon unquestioning trust in its own employees and constantly monitor its assets. At the same time, information security measures must be carried out constantly.

The article considers specific features of ensuring quality indicators of the technological process of sowing crops using coulters of various types. The existing designs of coulters are analysed, indicating their advantages and disadvantages. It is emphasised that the use of disc coulters for direct sowing is limited due to the need to apply significant efforts to deepen them into the soil. A well-known alternative design of operating parts for seed placement into the soil is a coulter with a sharp angle of entry, but its design and parameters need further improvement.The paper proposes the design of a sowing section for sowing spiked grain crops on the soil after no-till tillage methods with the presence of plant residues in the upper soil layers. The basis of this sowing section is a coulter with a sharp angle of entry into the soil, the design of which provides the use of a holding heel.
The article presents methodology for conducting field comparative tests of coulters with a sharp angle of soil penetration, which are represented by an experimental sowing section and a serial double-disc coulter with a packer roller. The section consists of a coulter with a sharp angle of penetration equipped with a holding heel.The performance was assessed by two indicators – uniformity of seed placement over the depth of seedbed and compliance with the specified seed placement depth. The working speed and the set seeding depth were taken as influential factors.The experimental section was mounted on a SZ-3.6 “Astra” grain seeder instead of one of the serial coulters being compared. The preliminary tillage was chiselling with surface disking. The coulters with a sharp angle of entry into the soil, which are equipped with the sowing section, are less dependent on the sowing speed, which makes it possible to perform sowing processes at higher operating speeds without reducing quality indicators.
It was found that the sowing section demonstrated a 7.5% better uniformity of seed distribution over the depth. This is most likely a positive consequence of the work of the holding heel.The actual seeding depth of both operating parts decreases with increasing working speed, the coulters deepen, but the degree of dependence for the experimental section is much lower than for the double disc coulter.

The development of the lavender business requires the expansion of the use of mechanization of technological processes, in particular, when sorting lavender seeds. The purpose of the research is to increase the productivity and quality of sorting lavender seeds by studying and using its physical and mechanical properties. Research methods: mathematical modeling, laboratory experiment, methods of mathematical statistics.
An analysis of existing lavender cultivation technologies and technical means for sorting seeds was carried out. The length, width and thickness of narrow-leaved lavender seeds and their frictional properties were determined. The influence of the angle of inclination of the surface on the coefficient of dynamic friction of lavender seeds was studied. The need to take into account the aerodynamic properties of seeds was identified. Based on the knowledge of these patterns, the design parameters were determined and an experimental installation for separating lavender seeds was manufactured. Its main elements are a screw seed dispenser with an electric drive, an inclined acceleration chute, an inclined friction sorting plane and a set of containers for sorted seeds. Laboratory experiments have confirmed its efficiency and high quality of sorting lavender seeds.
Lavender seeds have a length of 1.67–2.64 mm, a width of 0.93–1.32 mm and a thickness of 0.49–0.84 mm. The size distribution along the length corresponds to the normal law. The aerodynamic properties of seeds affect the patterns of their movement and require further study. It is also advisable to analyze the relationship between seed germination and their frictional properties. The developed installation for sorting lavender seeds in small private farms will allow to increase the productivity and quality of sorting lavender seeds.

Throughout the history of agriculture, farming has evolved from simple hand tools and animal-drawn machines to sophisticated automated equipment. One of the most promising technological solutions in agricultural production is the use of agricultural robots to ensure a high-quality and timely technological process. Agricultural robots are smart robots that can be controlled by various programs and software adapted to different technological operations. Bringing intelligence to agriculture, while increasing the efficiency and sustainability of agricultural production, ensures a future in which food is produced with minimal environmental damage.
The purpose of this article is to analyze the existing designs of agricultural robots for inter-row tillage, weed control, and spraying in the inter-row.
All of the analyzed designs of agricultural robots provide high-quality performance of one or more technological processes. However, there is one huge disadvantage: they are very expensive. In times of war, not all agricultural producers can afford such a device.
The functional capabilities of agricultural robots for inter-row tillage, weed control and spraying were analyzed. Their advantages and disadvantages are analyzed. The design of an agricultural robot is proposed to ensure high-quality work in the row spacing of row crops. Also, to unify the work of the agro-robot on one body, it is possible to create designs of various variations of the agro-robot, such as a transport unit and an intelligent sprayer.
The intellectualization of agriculture is moving towards enabling existing machines to work autonomously and without human intervention. The level of complexity of work that can be performed by agricultural robots is increasing. Agricultural robots, as the latest technology for agricultural production, not only save labor costs, but also improve quality control capabilities and increase the ability to withstand natural risks. Therefore, the proposed design of a simple and reliable agricultural robot to ensure high-quality work in the rows of row crops is a relevant and timely solution for agricultural production in our country.

Published: January 2025

The article presents the results of a study on the technological process of dehulling industrial hemp seeds. The aim of the study is to increase the productivity of the dehulling process while maintaining the integrity of the seed kernels. To achieve this goal, an experimental prototype of a centrifugal dehuller was developed, capable of processing seeds without the need for preliminary calibration or moisture normalization, significantly simplifying the raw material preparation process.
The study investigated the influence of key operating parameters of the mechanism on dehulling efficiency, including the rotational speed of the working wheel, feed rate, and seed moisture content. A multifactorial experiment was conducted, the results of which allowed for the identification of optimal parameter values to achieve maximum productivity and dehulling quality. The optimal parameters of the centrifugal dehuller were established as follows: working wheel rotational speed of 6200±200 rpm, feed rate of 100 kg/h, and raw material moisture content within 8.8–11.5%. Under optimal conditions, the throughput capacity of the mechanism was increased from 30 kg/h to 100 kg/h, ensuring a high yield of quality kernels.
Mathematical models of the dehulling process were developed to determine the dependence of the mechanism's efficiency on the selected parameters. It was found that significant deviations from the optimal parameter values negatively affect the efficiency of the process due to increased seed fragmentation.
The obtained results have significant practical importance for the industrial hemp processing sector, as the developed mechanism can be utilized to improve existing technological solutions. Further research is recommended to focus on enhancing the stability of the mechanism's operation under variable seed moisture conditions and increasing productivity, which will ultimately improve the efficiency of hemp production as a whole.

The work involves physical and mathematical modeling of the process of seed mixture movement along a designed helical surface of a feeder and its preliminary separation based on the physical and mechanical properties of the components, followed by directing them to the working surfaces of a vibro-friction separator. This ensures the achievement of the main condition for the quality separation process on the friction surfaces of such machines: dispersing the seed mass to the level of a monolayer in the feeding zone, which reduces mutual entanglement and deviation from the intended trajectories of the seed material components, thereby enhancing the efficiency of the separation process. The aim of the theoretical research was to numerically model the trajectory of the component mixture flow along the designed helical plate of the vibro-friction separator feeder and to justify the seed material feeding speed. In the calculations, the physical and mechanical properties of the seed mixture components were considered as ranges of their average values, accounting for normal distribution. The fractional content of the components in the seed mixture – χn, χd, χb, and the mixture feeding speed Q (units per second) were taken as the research factors. Based on the numerical modeling results of the component mixture flow trajectory along the designed helical plate of the vibro-friction separator feeder, the dependence of the total overlap area Sf of the component distribution across the width of the helical plate on the fractional content of the components in the mixture χn, χd, χb, and the feeding speed Q was determined. The evaluation criterion was that the total overlap area Sf should be minimal, and the feeding speed Q should be maximal.

Published: January 2025

Introduction: Condyle fracture is a fracture of the mandible which is quite common. Treatment of mandibular fractures can be with open reduction or closed reduction. This situation can be obtained by opening the fracture fragments, obtaining a normal relationship and fixing on its position. The goal of surgical treatment of fractures is to return the fracture fragments to their anatomical position. Surgical treatment can be intraoral or extraoral approach. The aim of this case report is to discuss the management of a patient with an unilateral condylar fracture of mandible through open reduction and internal fixation (ORIF) with an extraoral approach using the risdon technique.
Case: We report a case with complaints of pain when opening the mouth and limited mouth opening. Two and a half months prior to admission the patient had an accident but he refused ORIF treatment. One and a half months prior to admission, he complained of pain when opening his mouth and limited mouth opening. He had no infection and was diagnosed with Neglected fracture of left condyle.
Case Management: We performed head CT Scan to establish the diagnose. One day before the surgery, an interdental wiring fixation was performed to prepare for ORIF treatment. We performed ORIF with an extraoral approach using risdon technique. During the surgery we performed refracture and fixation using plate and screws. We followed up this patient until five months after the surgery. The result was acceptable and his complaints was resolved.
Conclusion: ORIF is the treatment of choice for neglected condylar fractures.

Introdução: O câncer do colo do útero continua sendo um problema de saúde pública apesar da possibilidade de rastreamento e diagnóstico precoce. Objetivo: Análise comparativa de 2.486 pacientes analíticas e não analíticas, encaminhadas ao INCA apenas para tratamento, com acompanhamento no hospital de origem, admitidas com câncer do colo do útero, entre janeiro de 2017 e dezembro de 2021, no Hospital do Câncer II (HCII/INCA), utilizando como base de dados o Registro Hospitalar de Câncer. Método: Estudo quantitativo e observacional dividido em quatro grupos: analíticos pré-pandemia, analíticos pandemia, não analíticos pré-pandemia e não analíticos pandemia. As cinco variáveis selecionadas foram analisadas de forma descritiva: tempo entre diagnóstico e admissão hospitalar, primeiro tratamento recebido no hospital, estado da doença após primeiro tratamento, razão para o não tratamento e estadiamento. Utilizou-se o teste chi-quadrado de Pearson para verificar a associação das variações das frequências com os períodos pré-pandemia e pandemia. Resultados: Entre as pacientes analíticas, na pandemia, houve aumento de 34,1% na proporção de pacientes admitidas com mais de 61 dias após o diagnóstico, 4,6% de encaminhamentos ao suporte terapêutico e redução de 6,3% de casos com remissão completa da doença pós-tratamento. Entre as não analíticas, na pandemia, houve aumento de 20,6% da proporção de pacientes admitidas em estádio IV, 23,3% de pacientes submetidas a nenhum tratamento por avanço da doença ou falta de condições clínicas e 12,1% de encaminhamentos ao suporte terapêutico. Conclusão: A pandemia da covid-19 teve impacto negativo sobre a doença e o acesso ao sistema de saúde.
INVESTMENT ATTRACTIVENESS OF UKRAINE AND EU SUPPORT DURING CRISIS PERIODS

Published: January 2025

The study of Ukraine’s investment attractiveness during periods of crisis highlights the significant influence of external factors on the investment situation in the country, particularly regarding the inflow of Foreign Direct Investment (FDI). In the context of global and local crises such as the COVID-19 pandemic and Russia’s military invasion, Ukraine’s economic situation has experienced significant fluctuations, which have reflected on the investment climate. European Union countries play a key role in providing financial support, which is an important factor in stabilizing Ukraine’s economy during this period. The aim of this research is to assess investment flows from EU countries and the investment attractiveness of Ukraine during crisis times. One of the key aspects of the study is analyzing the dynamics of FDI from EU countries. During the analyzed period, the volume of investments fluctuated significantly, indicating the instability of the investment environment. The largest investments in Ukraine come from the Netherlands and Germany, indicating the long-term interest of these countries in the Ukrainian market despite the crisis periods. Despite difficulties, 57% of companies already operating in Ukraine plan to continue their investments, and 79% are ready to contribute to the country’s reconstruction after the war. This emphasizes the potential for economic recovery in the future, particularly due to international support. The methodology of the research includes both quantitative and qualitative methods of analysis, particularly statistical and comparative analysis. The practical value of the article lies in identifying the main factors affecting changes in the investment situation in Ukraine during crisis periods, as well as in developing recommendations to improve the investment climate. To enhance investment attractiveness and stabilize Ukraine’s economy, it is crucial to continue reforms in the legal system, combat corruption, and improve the business climate through deregulation and simplification of administrative procedures. Additionally, Ukraine needs to actively work on infrastructure recovery plans, which will create new investment opportunities. The success of these measures depends on achieving stability and security, which form the basis for Ukraine’s economic development in the future.

В умовах сучасного сільського господарства, що характеризується зміною кліматичних умов та зниженням родючості ґрунтів, існує нагальна потреба у збільшенні посівних площ під зернобобовими культурами. У цьому дослідженні запропоновано стратегії оптимізації поживних умов для вирощування гороху озимого з акцентом на ресурсозбереження та підвищення вмісту азоту в ґрунті. Для визначення ключових стратегій оптимізації технологій вирощування гороху зимуючого було проведено огляд існуючої літератури з питань вирощування озимого гороху, управління поживними речовинами та покращення родючості ґрунту. Крім того, були проведені польові експерименти та спостереження для оцінки ефективності сучасних біологічних добрив, регуляторів росту та контрольованих доз мінеральних добрив у підвищенні врожайності озимого гороху зимуючого та якості ґрунту. Застосування сучасних біологічних добрив, регуляторів росту та контрольованих доз мінеральних добрив рекомендується для підвищення врожайності та збагачення якості ґрунту. Крім того, пропонується вивчити можливість вирощування озимого гороху поряд з традиційно вирощуваним ярим горохом, оскільки озимий горох краще використовує зимові запаси вологи, що призводить до підвищення врожайності та раннього очищення поля для подальшого посіву сільськогосподарських культур. Впроваджуючи інноваційні стратегії, такі як застосування біологічних добрив, регуляторів росту та контрольованих доз мінеральних добрив, фермери можуть підвищити врожайність озимого гороху, покращити якість ґрунту та сприяти сталому розвитку сільськогосподарських практик. Це дозволить не лише стабілізувати врожайність культури, а й підвищити екологічну ефективність землеробства шляхом зменшення використання мінеральних добрив та збереження природного ресурсу ґрунту. Подальші дослідження щодо вирощування озимого гороху, зокрема в Південному Степу України, спрямовані на вирішення нагальних сільськогосподарських проблем у цьому регіоні.
