Authors: Ji Lingzhu
Published: June 2023

In current English learning, listening, and speaking is an important part of English learning. To cultivate students’ English listening and speaking ability and meet the demand for language communication improvement today, this paper uses big data technology as the main support to recognize, noise reduction and feature extraction of input speech using speech recognition algorithm, noise elimination algorithm and feature extraction algorithm, respectively. Obtain data related to students’ English listening and speaking abilities to form systematic and complete student big data. Through preprocessing and mining, it provides a basis for decision making in English listening and speaking teaching. According to the results of the analysis of students’ English listening and speaking ability, the percentage of students who liked English listening very much in the pre-test was 25% of the class, and the percentage of students who thought they could be optimistic about the hardships in learning was 18%. After practicing the improvement path, the percentages of students increased to 38% and 29%, respectively. The mean value of listening at the pre-test was 20.23, which was lower than the mean value of listening at the post-test, 21.72. The above experimental results are sufficient to show that the development of the pathway in this paper can make students more motivated and enthusiastic in learning English listening and speaking, and thus improve their English listening and speaking skills.

Authors: Ding Jian , Xu Zhiguang
Published: June 2023

In order to reduce energy dissipation and alleviate the energy crisis, this paper proposes an absorption mode of distribution network with distributed power supply. First of all, the starting power coefficient and cutting off power coefficient are set to reflect the efficiency of the inverter and obtain the active output power of the photovoltaic system. Then, the Gaussian iterative algorithm is used to calculate the power flow of the distribution network, which forms a model along with the branch switch to complete the variables optimization under the conditions that all power conversion elements are removed from the system and the security constraint is satisfied. Afterwards, through the apparent power of the distribution network node, the single feeder is transformed into two feeders to ensure the fixed voltage at the front end of the line and make the node voltage rise and exceed the limit. Meanwhile, the active power and reactive power are provided for distribution network to reduce the feeders voltage loss, the reasonable regulation measures are used to stabilize the voltage, and the constant power factor and voltage amplitude of the network connection point are added to address voltage over limit and lighten the influence of increasing distributed power on voltage rising. Finally, the size of voltage amplitude is referred to determine the reactive power, so as to realize reasonable absorption of distribution network. The analysis results show that the voltage regulation measures proposed significantly improve the overall absorption capacity of the power supply, with the capacity increased by 0.54MW and 0.2MW respectively.

Authors: Sun Dan , Zhou ZhiMin , Liao ZhiWu
Published: June 2023

In recent years, the frequent occurrence of earthquakes, landslides, debris flow and other geological disasters worldwide is endangering people's production and life, which not only causes serious damage to infrastructure, but also creates a certain degree of fear for people. Geological disaster is an open nonlinear complex system, which has extraordinary complex geological process, formation conditions, and causes. Therefore, it makes difficulty in capturing the dynamic information and searching for the global optimal solution. Meanwhile, traditional geological disaster warning system has the deficiencies of single disaster warning and low accuracy. In order to improve the level of early warning and detection of geological disasters, this paper combined the genetic algorithm with superior performance and Support Vector Regression (SVR) algorithm to establish a feasible and credible early warning and monitoring model for geological disasters. The experimental results show that the early warning and monitoring model proposed in this paper can greatly improve the ability of geological disaster prevention and early warning, and greatly improve the level of disaster prevention and early warning, with good engineering application value.

Published: June 2023

A LoRa (Long Range Radio) based smart home product interaction system for the elderly is designed to solve the problem of reliability communication in the collection and information transmission of smart home environment parameters, device status parameters and the complex layout of communication lines inside smart devices. A privacy-preserving data aggregation scheme without a trusted authority center is proposed to address the privacy protection problem in the process of Internet of things (IoT) data collection. Firstly, without relying on the trusted authority center, the key exchange algorithm is used to generate shared secret keys and construct encryption keys among terminal devices to ensure the privacy of reported data; secondly, a fault tolerance mechanism is designed according to Carmichael’s theorem, so that the control center can still aggregate the received data when the terminal device fails or the network connection is wrong; in addition, the batch In addition, the integrity of the reported data is ensured by means of batch verification. Finally, the theoretical analysis proves the correctness and security of the scheme in this paper. The performance experiments show that the required computational overhead is lower compared to existing schemes, while some communication overhead is increased in order to have fault tolerance and to improve the verification efficiency of digital signatures. The application of this system will highlight the main position of the elderly, so that they can truly experience and accept the benefits of smart home for their lives and improve their quality of life.

Published: June 2023

Introduction

Because of the activities and effects they induce, hormones are prohibited for use for anabolic purposes in farm animals intended for slaughter, which is regulated in the European Union by relevant legal provisions. Therefore, there is an obligation to monitor residues of hormones in animals and food of animal origin to ensure consumer safety. A hormone banned but used formerly for fattening cattle, stanozolol, and its metabolite 16β-OH-stanozolol are synthetic compounds that belong to a large group of steroid hormones. This study investigates residues of these compounds in animal urine.

Material and Methods

From 2006–2022, 2,995 livestock urine samples were tested for stanozolol residues in Poland as part of the National Residue Monitoring Programme. A liquid chromatography–tandem mass spectrometry method to determine stanozolol and 16β-OH-stanozolol in animal urine was developed and validated according to the required criteria. Urine sample analysis was based on enzymatic hydrolysis of hormones potentially present in it to the free form, extraction of them from the sample with a mixture of n-hexane and butyl alcohol, purification of an extract on an NH2 amine column and finally, instrumental detection.

Results

The apparent recovery and precision parameters of the developed method were in line with the established criteria, while its decision limits CCα and detection capabilities CCβ were lower than the recommended concentration for analytical purposes set at 2 μg L−1 (valid until December 15, 2022; currently set as 0.5 μg L−1).

Conclusion

All examined samples were compliant with the evaluation criteria.

Ductal carcinoma in situ arises from microglandular adenosis and atypical microglandular adenosis in a young woman
Authors: Thu Huong Nguyen , Hue Tran-Thi , Duy Hung Nguyen , Minh Duc Nguyen
Published: June 2023

Microglandular adenosis (MGA) and atypical microglandular adenosis (AMGA) are intensely rare and distinctive forms of adenosis of the breast, usually occurring in middle-aged women. Carcinoma arising in MGA is an extremely rare subtype of breast carcinoma, and most reported cases are of invasive carcinoma. Ultrasound and magnetic resonance imaging are accurate imaging modalities for diagnosing these abnormalities. Our goal in this article was to report a rare instance of ductal carcinoma in situ (DCIS) arising from MGA and AMGA in a very young Vietnamese woman who presented with a palpable mass in her right breast for 1 month. During clinical examination and imaging, suspected lesions were found and categorized as BI-RADS 4a. The final histopathological findings confirmed DCIS arising from MGA/AMGA. In this patient, the disease was detected and managed early when the lesion was localized in the duct and there were no signs of invasive ductal carcinoma.

Authors: Faraj Moneer K. , Al-Musawi Mustafa Salih , Ali Abdulameer Tabarek
Published: June 2023

Background:

This study evaluates an alternative to the classical method of head fixation during Gamma Knife radiosurgery using a Leksell head frame. In the Gamma Knife® Icon™ model, a new method of head fixation is used by utilizing a thermal molded polymer mask that takes the shape of the patient’s head before fixing the head to the table. However, this mask is for single use and quite expensive.

Methods:

We describe a new, very economical method to fix the head of the patient during radiosurgery. We used commercial, quite cheap material [polylactic acid (PLA)] plastic and made a 3D printing model for the patient’s face, taking special measurements to put this mask and fix it on the Gamma Knife. The actual material cost is only $4 (100 times less than the original mask cost).

Results:

The new mask efficiency was tested using the movement checker software, the same one used to measure the efficiency of the original mask.

Conclusion:

The newly designed and manufactured mask is quite effective for use with the Gamma Knife® Icon™, with a much lower cost, and it can be manufactured locally.

Published: June 2023

Background:

We previously demonstrated the usefulness of periorbital electrodes in supplemental recording to detect epileptiform discharges in patients with mesial temporal lobe epilepsy (MTLE). However, eye movement may disturb periorbital electrode recording. To overcome this, we developed mandibular (MA) and chin (CH) electrodes and examined whether these electrodes could detect hippocampal epileptiform discharges.

Methods:

This study included a patient with MTLE, who underwent insertion of bilateral hippocampal depth electrodes and video-electroencephalographic (EEG) monitoring with simultaneous recordings of extra- and intracranial EEG as part of a presurgical evaluation. We examined 100 consecutive interictal epileptiform discharges (IEDs) recorded from the hippocampus and two ictal discharges. We compared these IEDs from intracranial electrodes with those from extracranial electrodes such as MA and CH electrodes in addition to F7/8 and A1/2 of international EEG 10-20 system, T1/2 of Silverman, and periorbital electrodes. We analyzed the number, rate of laterality concordance, and mean amplitude of IEDs detected in extracranial EEG monitoring and characteristics of IEDs on the MA and CH electrodes.

Results:

The MA and CH electrodes had nearly the same detection rate of hippocampal IEDs from other extracranial electrodes without contamination by eye movement. Three IEDs, not detected by A1/2 and T1/2, could be detected using the MA and CH electrodes. In two ictal events, the MA and CH electrodes detected the ictal discharges from the hippocampal onset as well as other extracranial electrodes.

Conclusion:

The MA and CH electrodes could detect hippocampal epileptiform discharges as well as A1/A2, T1/T2, and peri-orbital electrodes. These electrodes could serve as supplementary recording tools for detecting epileptiform discharges in MTLE.

Authors: Aleid Abdulsalam Mohammed , Alaethan Mohammed Hijji , Alsaati Ahmed Abdulaziz , Alhejji Murtadah Hassan , Ali Alkathem Jafar
Published: June 2023

Background:

Medullary brainstem lesions are rare tumors that are challenging to treat due to their location in the brainstem, which controls vital functions such as breathing, heart rate, and blood pressure. While the most common subtype is the aggressive diffuse intrinsic pontine glioma, other subtypes exist, including focal brainstem gliomas and cervicomedullary gliomas. The prognosis for patients with brainstem gliomas is generally poor, and treatment options are limited. Early detection and treatment are crucial to improve outcomes for patients with these tumors.

Case Description:

In this case report, the authors describe a 28-year-old male from Saudi Arabia who presented with headaches and vomiting. Imaging studies and clinical examination revealed a high-grade astrocytoma medullary brainstem lesion. The patient underwent radiation therapy and chemotherapy, effectively controlling tumor growth and improving his quality of life. However, a residual tumor remained, and the patient underwent neurosurgery to resect the remaining tumor was successful in removing the tumor, and the patient showed significant improvement in his symptoms and overall health.

Conclusion:

This case highlights the importance of early detection and treatment of medullary brainstem lesions. While radiation therapy and chemotherapy are primary treatment options, neurosurgery may be necessary to resect residual tumors. In addition, cultural and social factors may need to be considered in managing these tumors in Saudi Arabia.
A case of infectious intracranial aneurysm that formed and ruptured within a few days after occlusion of the proximal middle cerebral artery by infective endocarditis
Authors: Yanagawa Taro , Ikeda Shunsuke , Yoshitomi Shota , Shibata Aoto , Ikeda Toshiki
Published: June 2023

Background:

Embolic cerebral infarction and infectious intracranial aneurysms (IIAs) are well-known central nervous system complications of infective endocarditis (IE). In this report, we describe a rare case of cerebral infarction caused by the occlusion of the M2 inferior trunk due to IE, followed by the rapid formation and rupture of IIA.

Case Description:

A 66-year-old woman was admitted to the hospital with a diagnosis of IE and embolic cerebral infarction after being brought to the emergency department with a 2-day history of fever and difficulty walking. After admission, she was immediately started on antibiotic therapy. Three days later, the patient suddenly became unconscious, and a head computed tomography (CT) scan showed massive cerebral hemorrhage and subarachnoid hemorrhage. Contrast-enhanced CT showed a 13-mm large aneurysm in the left middle cerebral artery (MCA) bifurcation. An emergency craniotomy was performed, and intraoperative findings revealed a pseudoaneurysm at the origin of the M2 superior trunk. Clipping was considered difficult, so trapping and internal decompression were performed. The patient died on the 11th day after surgery due to the worsening of her general condition. The pathology of the excised aneurysm was consistent with a pseudoaneurysm.

Conclusion:

IE may cause occlusion of the proximal MCA and rapid formation and rupture of IIA. It should be noted that the location of IIA may be a short distance away from the occlusion site.

Published: June 2023

Aliphatic C(sp3)‒H bonds are inherently difficult to activate owing to their inertness and chemical indistinguishability. This challenge has been overcome mostly by directing group approach however the regioselectivity in distal aliphatic positions has mostly been substrate dependent, with substrate biasness being a pre-requisite for distal C(sp3)‒H activation; a direct consequence of the Thorpe-Ingold effect. Extending the methodology to fully unbiased straight chain aliphatic substrates, in which all the available positions are sterically and statistically equally probable for functionalization and in which the Thorpe-Ingold effect loses its significance, has been a long-standing problem. To this aim, we developed a ligand enabled orthogonal selectivity between the proximal γ and distal δ positions of such fully unbiased straight chain aliphatic amines in a regioselective fashion. These straight chain alkyl amines, though both δ and γ positions are equally probable for functionalization, can be orthogonally functionalized between these two positions just by changing the ligand, all other reaction parameters remaining constant; signifying the immense importance of ligand in controlling the selectivity between the aforementioned positions of such inert aliphatic C(sp3)‒H bonds. Experimental as well as DFT studies have been carried out to generalize the nature of ligand that would be promoting the orthogonal selectivity between these positons, with electron-rich pyridone ligands favoring selective distal δ functionalization while electron-deficient pyridone ligands tuning the selectivity favorably towards the γ position. This regioselective orthogonal selectivity tuned from γ to δ positions have also been mechanistically established through control reactions, kinetic studies and theoretical calculations.

Discovery of new to nature ‘de novo’ macrocyclic peptides has been greatly facilitated by the integration of genetic recoding approaches with peptide display technologies. Perhaps most important among the changes that can made to a peptide to allow its use in a biological setting is macrocyclisation, which has beneficial impacts on target affinity, selectivity, stability, and cell permeability. However, introducing macrocyclisation into a linear sequence is unlikely to be successful unless the sequence is already primed to adpot an appropriate conformation. As a result it is important to include cyclisation already at the discovery stage, meaning there is a need for more diverse cyclisation options that can be deployed in the context of peptide display techniques such as mRNA display. In this work we show that meta-cyanopyridylalanine can be ribosomally incorporated into peptides, forming a macrocycle in a spontaneous and selective reaction with an N-terminal cysteine generated from bypassing the initiation codon in translation. This reactive amino acid can also be easily incorporated into peptides during standard Fmoc solid phase peptide synthesis, which can otherwise be a bottleneck in transfering from peptide discovery to peptide testing and application. We demonstrate the potential of this new method by discovery of macrocyclic peptides targeting influenza haemagglutinin, and molecular dynamics simulation indicates the mCNP cross-link stabilises a beta sheet structure in a representative of the most abundant cluster of active hits. Our new approach generates macrocycles with a more rigid cross-link and with better control of regiochemistry when additional cysteines are present, also allowing easy access to spontaneously forming bicyclic peptides, and so is a valuable addition to the mRNA display toolbox.
Experimental Phase Diagram and Its Temporal Evolution for Submicron 2-Methylglutaric Acid and Ammonium Sulfate Aerosol Particles

Published: June 2023

Liquid–liquid phase separation (LLPS) in aerosol particles is important for the climate system due to its potential to impact heterogeneous chemistry, cloud condensation nuclei, and new particle growth. Our group and others have shown a lower separation relative humidity for submicron particles, but whether the suppression is due to thermodynamics or kinetics is unclear. Herein, we characterize the experimental LLPS phase diagram of submicron 2-methylglutaric acid and ammonium sulfate aerosol particles and compare it to that of supermicron-sized particles. Surprisingly, as the equilibration time of submicron-sized aerosol particles was increased to 60 min, the experimental phase diagram converges with the results for supermicron-sized particles. Our findings indicate that nucleation kinetics are responsible for the observed lower separation relative humidities in submicron aerosol particles. Therefore, experiments and models that investigate atmospheric processes of Aitken and accumulation mode organic aerosol particles may need to consider the temporal evolution of aerosol LLPS.

Authors: Sun Weisheng
Published: June 2023

Objective: To analyze the effect of early rehabilitation on motor dysfunction in patients with acute cerebral infarction. Methods: A total of 70 patients with acute cerebral infarction admitted to Suqian Zhongwu Hospital (our hospital) from January 2020 to December 2021 were selected as research subjects. The participants were divided into two groups through envelopes. The patients of the reference group (n = 35) received conventional treatment whereas the observation group underwent early rehabilitation and conventional treatment (n = 35). The scores of limb motor function (Fugl-Meyer Assessment [FMA]), functional independence (Barthel Scale), and Motor Assessment Scale (MAS) of the two groups were compared. Results: There was no significant difference between the scores of the two groups before treatment (P > 0.05); after early rehabilitation, the FMA and Barthel scale scores of the observation group were higher than those of the reference group, and the MAS scores of the observation group were also better than the reference group (P < 0.05). Conclusion: Early rehabilitation treatment on the basis of conventional treatment for patients with acute cerebral infarction can promote the recovery of motor function and improve the ability to perform daily activities of patients, thus it should be popularized.

Voltando o olhar para o ambiente interno das organizações, assimila-se que a constituição dos processos diversos e a forma como se manejam os recursos impactam diretamente no desenvolvimento e no alcance dos objetivos empresariais e como condutores para atingir essas propostas têm-se as lideranças em nível estratégico na organização. Para que isso ocorra de maneira a beneficiar, otimizar e efetivar os resultados obtidos pela gestão lança-se o pressuposto de reconhecimento do perfil do líder, incluso ao papel organizacional praticado e compreendido pelos princípios que sustentam a organização. Nesse sentido, em vista da relevância da temática e sabendo que a comunidade LGBT+ se caracteriza como grupo minoritário, cabe refletir sobre os aspectos de liderança e da inserção desse grupo em empresas da microrregião de Adamantina. Para tanto, este estudo analisou dados extraídos em pesquisa com 32 empresas das cidades de Adamantina e Lucélia, a fim de traçar a configuração dessas organizações para com os colaboradores LGBT+, dado o fator de inclusão, a sua mensuração na contribuição com o papel organizacional, e o posicionamento das empresas em relação às lideranças LGBT+, tendo em vista a ausência prática da inclusão do grupo nos contextos organizacionais nas cidades do interior. O objetivo se fixou em conceituar e contextualizar, com bases teóricas, os assuntos inerentes à comunidade LGBT+, às lideranças, bem como o papel do líder e sua constituição, e da realidade das cidades em que se encontram as empresas que compuseram a pesquisa, fornecendo dados necessários para as discussões e pontuações a respeito da temática. Para a realização da pesquisa foi distribuído, aleatoriamente, um questionário on-line às empresas que participam da economia da microrregião de Adamantina, obtendo-se 32 respostas, que foram analisadas de maneira comparativa e crítica, possibilitando a construção dos gráficos oferecidos no presente artigo, demonstrando, nessa amostragem das empresas que compuseram a pesquisa, que mais da metade pontuou ter ciência de LGBT+ no quadro funcional, porém somente 5,5% dessas organizações alocam esse capital intelectual no nível estratégico, que agrupa, em si, os cargos de liderança das organizações.

Authors: Khrystyna Khimenes , Yuriy Briskin , Maryan Pityn , Lyubomyr Malanyuk
Published: June 2023

The aim of the study. To systematize factual data on the formation and development of the competition system components in professional tennis before the beginning of the "tennis open era". Material and methods. Facts from the history of the formation of systematicity in professional tennis competitions and the formation of key competitions in the period up to 1968 was the main material of the research. The results. The era of modern tennis begins in the second half of the 19th century. It was found that the game began to be commercialized already in 1894, and this process began with the sale of tennis training equipment and textbooks. The first competitions, which were open to everyone, including professional tennis players, were held in Great Britain (Wimbledon tournament, 1875), but they cannot be called professional, since in British society attention was focused on the development and popularization of amateur sports. Summarizing the facts made it possible to find out that tennis began to develop as a professional sport in the United States, where were favorable economic and geopolitical conditions for this. Here, in 1926, the promoter K. Pyle held exhibition tours exclusively for professional tennis players with whom he concluded contracts. It was found that in the late 20s – early 30s of the XX century, three professional tennis majors of those times were created – U.S. Professional Championship, Wembley Professional Championships and French Pro Championship. These competitions actually set the pace for the development of the direction. It is established that characteristic for that time was a constant change in the number of participants, the format of holding and the surface of the tournament courts. The key barrier (separation between amateur and professional tennis) was overcome in 1968. In addition, the experience gained in the past in organizing professional tennis tournaments gradually received a new level of adaptation in the “Open Era tennis”. However, the period until the 1980s remained difficult to determine a unified attitude of the leading tennis organizations in the world to the process of its further professionalization. Conclusions. Tennis as a type of professional sport began to form in the US at the end of the 19th century and immediately developed dynamically, at the same time separated from the amateur (until 1968). The main tournaments (majors) of that time were the U.S. Professional Championship, Wembley Professional Championships and French Pro Championship, However, others tournaments developed too and they were even a priority for many leading professional tennis players periodically. The competition system was not stable, competition formats often changed, but professional tennis gained popularity and increasingly became a source of income for the athletes themselves and entire organizations.

Authors: Svitlana Biriuchynska , Victoriia Biletska
Published: June 2023

Introduction. The article examines modern methods of evaluating the performance of fitness club employees and analyzes approaches to evaluating the work of staff in leading international companies. The advantages and disadvantages of using separate methods for evaluating the fitness clubs’ staff are determined. The purpose of the work is to determine approaches to evaluating the work of staff in leading international companies and to analyze modern methods of evaluating the performance of employees of fitness clubs. Results. The study shows the peculiarities of using quantitative methods in the fitness industry to evaluate the work of staff: the method of return of investment (ROI), the method of determining key performance indicators (KPI), benchmarking. It has been established that the ROI method is suitable for evaluating the work of employees related to the provision of services, working with clients (fitness coaches). Most of the KPI indicators are of strategic importance specifically for the fitness sector, because with the help of KPI it is possible to create a system for evaluating the performance of individual employees, departments, and the fitness club in general. The benchmarking method in the field of fitness is used to adopt the experience of world fitness clubs and introduce new training programs or new training formats. The vectors of the application of qualitative methods have been determined: the "360 degrees" method - for preliminary formation of the personnel reserve of fitness personnel, identification of the need for training, assessment of its results, creation of individual development plans for each employee of the fitness club; psychological methods - complement the picture of leadership qualities and skills of an employee. The use of combined methods (the DISC INSURANCE method, the HOGAN method) allows you to optimize work in the fitness club team, choose the optimal position for the employee to maximize the realization of professional qualities and potential, and improve the psychological climate in the team.

Such a study is taking place in Ukraine for the first time. The study aims to check the reliability of the Ukrainian version of the questionnaire Multidimensional Assessment of Interoceptive Awareness, Version 2 (MAIA-2 ukr), and compare the data with the original versions. The results. Four hundred first-year Borys Grinchenko Kyiv University students took part in the study. The sample was relatively homogeneous — all students were 17-18 years old (80.3% women and 19.7% men) and consented to process personal data. It was the first attempt at the end of 2022 with this contingent, and the translation for which was refined. Two more such attempts for 2023 we planned. Used IBM SPSS Statistics, the validation results are consistent with the original versions of the Multidimensional Assessment of Interoceptive Awareness. Conclusions. For the first time in Ukraine, the results of verifying the Ukrainian adaptation of the Multidimensional Assessment of Interoceptive Awareness, Version 2 (MAIA-2) questionnaire, its reliability, and consistency of interoceptive dimensions have been published. The revealed connections of elements in the correlation matrix have a high statistical significance (Determinant = 1.11E-007). Additional tests indicate the desired measure of sampling adequacy (Kaiser-Meier-Olkin test = 0.889) and a high criterion of sphericity (Barlett's test: Chi-Square = 6179.671, p<0.001). For the early stage of the study, the reliability coefficient (Cronbach's alpha), which assesses the internal consistency of the items of the scales, corresponds to the recommended value for all interoceptive dimensions.

Introduction. One of the types of biochemical reserves of the human body is the antioxidant system, which reverses the destructive effect of free radicals and keeps the level of lipid peroxidation (LPO) within physiologically safe limits. The article presents the results of determination of the antioxidant properties of the blood of wrestlers and boxers at rest and after physical activity for 10 minutes of recovery, after 1 hour and in the morning of the next day. The activation of LPO under the influence of physical activity is one of the manifestations of the general adaptation syndrome - stress, and the quantification of its parameters is important for the timely use of antistress agents and measures. The purpose of the study: to study the informative indicators of the antioxidant system of the blood of athletes of different specializations at rest and after the influence of physical activity. Materials and methods. The study involved 21 high-class athletes (men and women) aged 19-30 years. The content of TBA-active products was determined in the capillary blood of athletes by the colorimetric method of reaction with thiobarbituric acid. The peroxide resistance of erythrocytes was studied using a photometer LP-400, "Dr. Lange" (Germany), using ready – made reagent kits. Statistical processing of the data was performed using standard computer programs. Results. After control-training loads lasting about 1.5 hours in representatives of Greco-Roman wrestling and boxing, the content of TBA-active products and erythrocyte peroxidation increased significantly relative to the resting state at the 10th minute of recovery, after an hour and in the morning of the next day. The increase in the content of TBA-active products and erythrocyte hemolysis under the influence of physical activity indicates excessive activation of the process of free radical generation and increased LPO due to insufficient antioxidant protection. Conclusions. Summarizing the analysis and interpretation of the results of the study presented in this paper, as well as the results of previous studies, we can consider the fact of activation of LPO in tissues that function intensively during intense muscle activity and the important role of the body's AO system in ensuring high physical performance to be convincingly proven. The specificity of the functioning of individual mechanisms in various sports is an objective basis for the choice of means and methods of their correction, which provides a protective effect against the negative effects of increased free radical reactions and thereby increases the body's resistance to free radicals, stimulates the efficiency of muscle activity and accelerates the recovery process.

The development of technology in the transportation sector at this time is increasingly crucial. So the company innovates to create a car that can run itself with a high level of security. In this study, we designed an autonomous drive system for a 1:10 scale RC car using the main components in the form of a Raspberry Pi 4 and a Raspberry Pi camera as image processing for automatic control of an self driving car. Then the Arduino Nano, BTS7960, and Driver L298N components are used to regulate the movement of the DC motor. In this article, the control strategy of this self-driving car will be shown which will be implemented to detect lanes as a guide to walk autonomously. This study uses the HSV color filer method with morphology techniques to detect the path to be passed. This study resulted in a path detection that was very accurate and operated in real-time when compared to the CNN method using sampling paths to be passed that had previously been researched. After the path is detected, the interconnection between the mini computer and the microcontroller will work to synchronize the path detection and motor movement. In trials and hardware implementations carried out in the self-driving car laboratory with artificial intelligence, it can work according to the algorithm created with a success rate of 90%.

In this study, the analysis of the effect of loading on the DGA results of the Paiton UAT 2A transformer units 1 and 2 was carried out using the DGA (Dissolved Gas Analysis) test tool with the X-DGA kelman tool to determine the gas content contained in oil or oil. The UAT 2A transformer is a type of oil-cooled distribution transformer that uses the Nytro Libra oil type. The oil in the UAT 2A transformer is useful for insulating and cooling media so that the UAT 2A transformer does not get hot. In the oil content there is a gas content that causes transformer failure. Gas failure is called gas fault which results in thermal and electrical failure. The results of the DGA (Dissolved Gas Analysis) test analysis show that loading greatly influences the DGA test results because there are contents that are indicated to experience Low Energy Electrical Discharge, Hight Energy Electrical Discharge and Thermal Fault, namely H2, CH4, C2H4, C2H6, C2H2, CO, CO2, and H2O continue to increase due to Thermal Fault
