Authors: Усачук Анатолий Николаевич , Горошников Андрей Алексеевич , Мимоход Роман Алексеевич 
Published: April 2023

В 2022 г. во время продолжающихся раскопок поселения позднего бронзового века Панагия 1 в юго-западной части Таманского п-ва среди большого количества различных костяных изделий были выделены при трасологическом изучении три орудия первичного цикла работы с шерстью: ламель (стригальная полочка), применяемая как пластина-упор для срезания металлическим лезвием шерсти овцы во время стрижки, и остатки зубьев гребней-кард для расчесывания овечьей шерсти, удаления из нее спутанных участков, грязи и мусора. На основе привлечения большого круга аналогий авторы исследуют историографию вопроса, разбирают ошибки, допущенные в процессе изучения, а на основе трасологического анализа – взвешивают все «за» и «против» в процессе реконструкции способов изготовления и использования этих категорий костяных орудий. Попутно поднимается вопрос о наличии в погребениях эпохи бронзы разных типов гребней. Предлагаются и обосновываются изменения в названиях орудий и их частей, затрагиваются вопросы ритуального использования орудий.

Informal Self-Employment in the Market of Tutoring Services: International Experience of State Regulation
Authors: Donetskaya S. S. , Tretyakova V. A. 
Published: April 2023

Private tutoring is currently an international phenomenon and, as research in this field demonstrates, has a pronounced upward trend in many countries around the world. At the same time, the issues of functioning and development of the tutoring services market remain insufficiently covered due to the lack of reliable information on tutoring services, imperfect legislative framework in this area, as well as due to the complex changes in the educational system and in the socio-economic life of society in general, to which the analyzed market is extremely susceptible. Therefore, the purpose of the article is to reveal the features of approaches and methods used in the international practice of regulating the tutoring services market.The article reveals that tutoring services market in any country, despite the sufficient openness to new participants, operates under certain restrictions: natural and unnatural barriers. The former is conditioned by the peculiarities of natural development and scale of the market; the latter are created through administrative control of tutoring activities. The classification of barriers is given, which makes it possible to single out state regulation of self-employment in the tutoring services market into a separate category. The types of state policy of different countries in relation to tutoring activities are presented. It is revealed that the current system of state regulation of the tutoring services market in Russia is characterized by a focus on tax control without considering the social significance of the nature of tutoring services and its impact on the state education system. In this regard, it is necessary to analyze international experience, especially about the possibility of implementing the most successful solutions of state regulation of the tutoring services market in relation to Russian conditions.
Coil embolization for post-bypass aneurysm of middle meningeal artery for moyamoya disease – preservation of transdural anastomosis
Authors: Maruyama Kunitaka , Kashiwazaki Daina , Yamamoto Shusuke , Akioka Naoki , Hori Emiko , Kuroda Satoshi 
Published: April 2023

Background:
Middle meningeal artery (MMA) pseudoaneurysm following revascularization surgery for moyamoya disease (MMD) is rare.

Case Description:
Here, a 29-year-old man presented with an MMA pseudoaneurysm after he underwent revascularization surgery (superficial temporal artery-to-middle cerebral artery bypass and encephalo-duro-myoarterio-pericranial synangiosis) for hemorrhagic MMD. At 3 months post-surgery, digital subtraction angiography showed a pseudoaneurysm in the right MMA. Transdural anastomosis to the parietal and occipital lobes was opacified at the distal MMA of the pseudoaneurysm. Intra-aneurysmal coil embolization was performed for preservation of transdural anastomosis. The postoperative course was uneventful. At 1 month post-embolization, angiography revealed an entirely occluded pseudoaneurysm.

Conclusion:
An increase in blood flow in the MMA due to bypass surgery may accelerate aneurysm development by increasing the hemodynamic stress. This case suggested that intra-aneurysmal embolization may be a potential treatment.
A combined, supraclavicular, infraclavicular, transaxillary, and posterior subscapular approaches for en bloc resection of giant myxofibrosarcoma
Authors: Bethel Jacob A. , McCarthy Daniel P. , Weisman Paul S. , Glazer Tiffany A. , Hanna Amgad S. 
Published: April 2023

Background:
Myxofibrosarcoma (MFS) is a rare and locally infiltrative tumor that commonly occurs in extremities in older adults; however, truncal and head and neck cases have been reported. They are characterized by multinodular growth, incomplete fibrous septa, and myxoid stroma. Surgical resection is the mainstay of treatment.

Case Description:
The authors report a case of a combined, supraclavicular, infraclavicular, transaxillary, and posterior subscapular approaches for resection of giant MFS.

Conclusion:
The anatomical complexity and rarity of tumors involving the brachial plexus impose many challenges onto surgeons performing surgical resections. Treatment choices and surgical outcomes rely heavily on meticulous multidisciplinary planning, anatomical knowledge, careful dissection, and extent of resection. This case is unique in utilizing four different approaches to the brachial plexus to resect one tumor.

Waduk atau tampungan merupakan kolam besar di alam yang dibuat dengan cara membangun bendungan untuk menampung air pada saat air berlebih (musim hujan) untuk digunakan pada waktu dibutuhkan. Desa Jelantik memiliki sebuah waduk yang masyarakat sebut Telaga Ijo. Kunci dari kelestarian waduk adalah terjaganya lingkungan sekitar waduk. Kelestarian waduk dapat dilakukan dengan menjaga lingkungan sekitar waduk tetap hijau melalui penghijauan dan menjaga kebersihan air di waduk. Namun untuk menjaganya membutuhkan pendekatan, sosialisasi dan edukasi ke masyarakat. Masih banyak masyarakat tidak peduli lingkungan karena keterbatasan pengetahuan yang dimilikinya. Membangun kesadaran masyarakat untuk cinta dan peduli lingkungan tidaklah mudah, memerlukan proses yang panjang melalui kerjasama berbagai pihak, sikap saling percaya dan menumbuhkan komitmen bersama. Metode yang digunakan dalam kegiatan pengabdian ini dengan metode PAR (Participatory Action Research) yang merupakan edukasi berdasarkan teori dan praktek. Hasil kegiatan menunjukkan edukasi berbasis teori menekankan pada pengelolaan lingkungan hidup, pentingnya air bagi kehidupan dan penghijauan. Sedangkan edukasi berbasis praktek yaitu dengan penanaman berbagai jenis pohon di sekitar waduk Jelantik. Hasil dari aplikasi edukasi tersebut menunjukkan kepedulian masyarakat terhadap lingkungan semakin baik. Hal tersebut dapat dilihat dari antusiasnya masyarakat dari anak-anak hingga orang dewasa

Background At the time when COVID-19 was declared a pandemic in March 2020, its spread in the African continent was slow. However, confirmed cases of the virus have since risen steadily over the years in the African continent for many reasons. This study aimed to determine factors associated with perceptions of COVID-19 vaccines among adult age-group populations in northern Uganda. Methods We conducted this study as part of a larger study to determine factors associated with COVID-19 vaccine hesitancy/acceptance among 723 adult age-group populations selected by stratified and systematic sampling approaches from northern Uganda. We used a questionnaire with an internal validity of Cronbach’s α= 0.772. A five-point Likert scale, with responses categorized as strongly agree “SA”, agree “A”, neutral “N”, disagree “DA”, and strongly disagree “SD”, was used to assess participants’ perceptions on COVID-19 vaccines. A multivariable regression analysis was conducted with P-value set at <0.05. Results Overall, 723 participated in the study with a mean age of 31.4 years (standard deviation, SD, +10.1). The majority 54.5% (n=394) were males. There were no significant differences in perceptions of COVID-19 vaccines among age-group populations (adjusted odds ratio, aOR=0.99, 95% confidence interval, CI=0.98-1.01). Key finding include: (i) it was important to take a COVID-19 vaccine (aOR=1.02, 95% CI=1.00-1.04); (ii) vaccines have unlikely unforeseen side effects (aOR=0.98, 95% CI=0.97-0.99); (iii) vaccines were unlikely being promoted for commercial gains (aOR=0.98, 95% CI=0.97-0.99); and children could take COVID-19 vaccines (aOR=1.02, 95% CI=1.00-1.03). Stratified by age-groups, the 20–29-year-old perceived COVID-19 vaccines developed in Uganda as unlikely safe and effective (aOR=0.59, 95% CI=0.35-0.97), and COVID-19 vaccines have likely unforeseen side-effects (aOR=2.1, 95% CI=1.3-3.6). While the ≥50-year-old group perceived that COVID-19 vaccines were unlikely being promoted for commercial gains (aOR=0.2, 95% CI=0.1-0.6). Conclusions There were no substantial differences in perceptions on COVID-19 vaccines in adult age-group populations in northern Uganda. The determinants of COVID-19 vaccine perceptions were its importance against the virus; vaccines have unlikely unforeseen side-effects, and children could take it. Stratified by age-groups, some age-groups perceived COVID-19 vaccines developed in Uganda as unlikely safe and unlikely being promoted for commercial gains.

Published: April 2023

Osmanlı toplumsal hayatı, II. Mahmud dönemindeki batılılaşma, yenilik hareketlerinin yanında, 3 Kasım 1839’da ilan edilen Tanzimat Fermanı ile birlikte kapsamlı bir değişim sürecine girmiştir. Bu değişim neticesinde sanat dallarında çeşitli reformlar ortaya çıkmış-tır. Geleneksel yaklaşımların yanında Batı ekolleri de yavaş yavaş etkisini göstermeye başlamıştır. Resimden heykele, edebiyattan müziğe sanatın hemen her alanında yeni yönelimler ortaya çıkmaya başlamıştır. Türk müziği icrâcılığı ve besteciliği alanında da bu yönelim ile birlikte, gelenekselden uzaklaşma ve batı formlarına doğru değişim ve dönü-şümler görülmüştür.
Osmanlı Devleti’nin kuruluşundan bu yana askerî müziğin resmî temsilcisi olan Meh-terhâne-i Hümâyun, II. Mahmud döneminde 1826 yılında görev kapsamı daraltılarak yerine, Batı müziği icrasını esas alan Mûzikâ-yı Hümâyun kurulmuştur. Bu değişim, Batı-lılaşma hareketinin müzik alanında da görülmeye başlandığını ifade etmektedir.
Batı standartlarında bir bando kurma düşüncesi ile İstanbul’da bulunan Fransız Manguel ilk olarak Mûzikâ-yı Hümâyun’da görevlendirilmiştir. Sonrasında İtalyan ekolünde yeti-şen Giuseppe Donizetti ile birlikte kurum istenilen seviyeye ulaşmaya başlamıştır. Donizet-ti, Mûzikâ-yı Hümâyun ustakârı unvanı ile göreve getirildiği gün itibari ile Batı müziği eğitimine başlayarak, kısa süre içerisinde saraya bağlı ilk Batı repertuvarı icra eden bando takımını kurmuştur.
II. Mahmud döneminden itibaren Cumhuriyetin kurulduğu döneme kadar Mûzikâ-yı Hümâyun faaliyetlerine devam etmiştir. Cumhuriyet’in ilanı ile birlikte Riyaset-i Cumhur Orkestrası adını alan Mûzikâ-yı Hümâyun, günümüzde Cumhurbaşkanlığı Senfoni Or-kestrası olarak faaliyetlerini sürdürmektedir.
Bu çalışmada 19. Yüzyıl’da faaliyet gösteren Mûzikâ-yı Hümâyun ile başlayan müzik reformları ve aynı yüzyılda Osmanlı Devleti’ndeki Batılılaşma temâyülü incelenecektir.

Published: April 2023

The most common supply of freshwater for drinking, irrigation, and other domestic uses is groundwater; however, because of increased radon concentrations brought on by mining activities, its quality is still a severe concern. Using a liquid scintillation detector, this study investigated the radon content, its related toxicity, and its risk to human health in the groundwater of the Keana in Nasarawa, Nigeria. Ten (10) borehole samples and five (5) well samples totaling fifteen (15) groundwater samples were taken. The results showed that the average radon concentration in water samples from Keana was 2.25 Bq/L. The mean annual effective dosage (ingestion) for adults and children in Keana was 0.016 mSv/y and 0.027 mSv/y, respectively. In Keana, the additional lifetime cancer risk per adult was 5.65 × 10–5, and per child, it was 8.79 × 10–5. The study’s radon concentration was lower than the benchmark of 11.1 Bq/L established in 1991 by the Nigerian Standard Organization and the US Environmental Protection Agency. The results of this study indicate that the level of radon is safe; as a result, people can continue farming and other activities. To reduce the risk of cancer, however, more research could be done in the area. Further research should be done by looking at additional sources in the study area in order to cover the entire zone. Further investigation should be carried out both during the dry and wet seasons because radon concentrations in groundwater alter over time due to dilution by recharge from rainfall.

Abstract
The authors of this manuscript present the development of a braking system with friction material base WC-Cu coating for the electric vehicle. This manuscript follows on from the original development of an AGV multi-disc braking system and an experimental investigation of the friction factor of WC-Cu coatings. In addition to developing the mechanical elements and construction of the electric vehicle, the tribological parameters of three samples of the steel substrate, the C45 with WC-Cu coating, were investigated in the tribological laboratory. A metallic coating of the WC-Cu base was applied on the C45 steel substrate using electro-spark deposition coating technology. The experiment used three samples with different percentage ratios of chemical elements in the coating structure. The tribometer working on a “Ball on Plate” principle was an investigation of the friction factor of all samples during the experiment. Subsequently, the surface of the samples was modified structure WC-Cu with laser technology. The microhardness of modified and unmodified coatings according to the Vickers methodology was investigated in the next stage. At the end of the experimental investigation, a braking simulation was created in the programming environment of the Matlab® software, considering all driving resistances. The researchers also focused on the simulation of heat conduction during braking for some considered driving modes with braking on a level and with a 20% slope roadway. The simulation of heat flow was carried out in the Matlab® programming environment using the Fourier partial differential equation for non-stationary heat conduction.

Introduction: In this paper we tried to conduct a novel nanomaterial strategy to overcome osteoarthritis (OA) in a mouse model.Methods: In this regard, after synthesizing the Mil-88a nanozyme, as a certain Fe-MOF, its toxic effects were detected by CCK-8 method and live-dead staining. The OA model of mouse was constructed, and paraffin sections of joints were taken for histological evaluation. In addition, immunofluorescence and immunohistochemistry were used to identify the OA progression and OARSI was used to evaluate the OA grades. We observed that Mil-88a could be easily synthesized and has high biocompatibility.Results: We observed that Mil-88a could significantly promote the expression of OA anabolism-related genes such as Col2 and also significantly inhibit the expression of OA catabolism-related genes MMP13. Besides, we observed better OARSI score in animals treated with Mil-88a nano-enzyme loading on organic metal matrix.Discussion: Overall, Mil-88a nano-enzyme could be used as a novel strategy to treat OA.

Published: April 2023

ObjectivesThe relationship between rheumatoid arthritis (RA) and coronary atherosclerosis is widely concerned, but observational studies have not clarified causality. We performed two-sample Mendelian randomization (MR) study to assess the causal association between RA and coronary atherosclerosis.Methodswe mainly conducted MR analysis using the inverse variance weighted (IVW) approach. Weighted median, MR-Egger regression and maximum likelihood were conducted as sensitivity analyses for supplementary analysis. Multivariate MR also were performed to validate the results of two-sample MR. Furthermore, we performed the MR-Egger intercept, MR-PRESSO, Cochran's Q test, and “Leave-one-out” to assess the levels of pleiotropy and heterogeneity.ResultsIVW result showed a positive link between genetic predisposition to RA and increased relative risk of coronary atherosclerosis (OR: 1.0021, 95%CI 1.0011-1.0031, P &lt; 0.05). The result was confirmed by the weighted median method (OR: 1.0028, 95%CI 1.0014-1.0042, P &lt; 0.05), MR-Egger regression (OR: 1.0031, 95%CI 1.0012-1.0049, P &lt; 0.05) and maximum likelihood (OR: 1.0021, 95%CI 1.0011-1.0030, P &lt; 0.05). Multivariate MR also reached a consistent conclusion. In addition, MR-Egger intercept (P = 0.20) and MR-PRESSO (P = 0.06) did not provide evidence of horizontal pleiotropy. Meanwhile, the results of Cochran's Q test (P = 0.05) and “Leave-one-out” failed to detect significant heterogeneity.ConclusionThe result of the two-sample MR analysis found genetic evidence to support the positive causal association between RA and coronary atherosclerosis, suggesting that active intervention for RA may reduce the incidence of coronary atherosclerosis.
