ОСОБЛИВОСТІ МІКРОКРИСТАЛІЗАЦІЇ РОТОВОЇ РІДИНИ В ДІТЕЙ ІЗ ЗУБОЩЕЛЕПНИМИ АНОМАЛІЯМИ
Authors: Лесіцький М.Ю.
Published: September 2021

Актуальність. Важливою функцією ротової рідини є мінералізувальна, оскільки вона забезпечує вторинну мінералізацію зубів після їх прорізування шляхом під- тримання гомеостазу порожнини рота, регулювання обмінних процесів в емалі зуба за рахунок врівнова- ження процесів демінералізаціїї та ремінералізації. Найпростішим та інформативним методом для вивчення балансу органічних та неорганічних ком- понентів та фізико-хімічних властивостей ротової рідини є оцінка мікрокристалізації ротової рідини. У процесі вивчення мікрокристалів ротової рідини враховується характер малюнку, що може свідчити про структурно-функціональні властивості емалі та резистентність органів та тканин порожнини рота в цілому. Особливої уваги заслуговує дослідження мікрокристалізації ротової рідини в дітей із різними видами зубощелепних аномалій, враховуючи можливі зміни складу та функціональної здатності рото- вої рідини при різній патології. Мета дослідження. Вивчення мікрокристалізації ротової рідини в дітей із зубощелепними аномаліями. Матеріали дослідження. Проведено вивчення особли- востей кристалоутворення у 88 дітей 12 та 15-річного віку із ЗЩА. Результати дослідження. У результаті проведених досліджень встановлено, що серед усіх обстежених дітей І тип мікрокристалізації ротової рідини виявлений, в середньому, лише у 32,95±5,01% дітей із ЗЩА, для якого характерним є чіткий рису- нок крупних подовжених кристалоприизматичних структур, які йдуть від центру краплі та утворю- ють так зване «листя папороті». Натомість ІІ та ІІІ тип кристалів зустрічається у 47,73±5,32% та 19,32±4,21% випадків. Встановлено, що серед дітей з карієсрезистентною емаллю І тип криста- лоутворення, за середніми даними, виявлений біль- шої половини обстежених із ЗЩА (у 53,33±7,44%), ІІ тип – у 35,56±7,14% дітей, натомість з ІІІ тип – лише в 11,11±4,68% випадків (р1>0,05, р2<0,001). Натомість серед дітей з ЗР-КС емаллю кристали І типу вста- новлено у 16,28±5,63%, ІІ тип – у 32,56±7,14% осію та ІІІ тип у 51,16±7,62%. Результати отриманих даних свідчать, що серед дітей із аномаліями окре- мих зубів та КР емаллю, за середніми даними, усі діти мали І тип мікрокристалізації. Серед дітей із УР-КС емаллю та аномаліями окремих зубів І тип криста- лів, за середніми даними, виявлений у 75,00±12,50%, а ІІ тип – у 3 рази рідше (у 25,00±12,50%, р<0,01). У дітей з аномаліями зубних рядів та КР емаллю І тип кристалів зустрічається у 61,90±10,59%, а у осіб із УР-КС емаллю – у 36,84±9,01%, р>0,05. При цьому увдітей з УР-КС емаллю та аномаліями зубних рядів частіше виявлені ІІ (на 10,54%) та ІІІ (в 3,31 рази) типи мікрокристалізації (р>0,05, р<0,05). Серед дітей з аномаліями прикусу встановлено достовірно вищу кількість осіб з КР емаллю та І типом кристалів у порівнянні з дітьми із УР-КС емаллю (в 6,46 разів, р<0,01) та тенденцію до збільшення кількості дітей із ІІ та ІІІ типом кристалів та УР-КС емаллю.

Мета дослідження – визначення мікробіологічного спектру та видового складу зубного нальоту у дітей із захворюваннями шлунково-кишкового тракту з ура- хуванням множинного ураження карієсом зубів. Методи дослідження. Для клініко-лабораторних досліджень було відібрано 120 дітей, з яких сформу- вали основну групу – 80 дітей з множинним карієсом на тлі захворювань ШКТ, та порівняльну групу – 40 дітей з інтактними зубами з аналогічними сома- тичними ураженнями ШКТ. Матеріалом для мікробі- ологічного дослідження був зубний наліт. Наукова новизна. Частота виділення та ступінь обсіменіння зубного нальоту у дітей з множинним карієсом була вищою, ніж у осіб з інтактними зубами та характеризувалася наявністю видоспецифічних мікроорганізмів. Насамперед варто зазначити, що за наявності уражень ШКТ специфічними мікроорга- нізмами в зубному нальоті дітей основної групи були Helicobacter pylori. Максимальна частота виділення припадала на Lactobacterium 68,5% за щільності коло- нізації 4,11±0,12 lgKYO/мл, (р<0,001) у дітей з мно- жинним карієсом. Були ідентифіковані грампозитивні факультативні палички Nocardia у дітей з множин- ним карієсом на фоні захворювань ШКТ, а грамне- гативні факультативні палички Proteus виявлялись у 2,2 рази частіше, ніж у дітей порівняльної групи. Висновки. Розширення спектра мікробних асоціацій, значне превалювання карієсогенних мікроорганізмів (Str.mutans, Str.sanguis, Lactobacterium) сприяло про- гресуванню патологічного процесу та переконливо доводить їх патогенетичну дію в розвитку множин- ного карієсу. Слід зауважити, що наявність у зубному нальоті Helicobacter pylorі варто розцінювати як додатковий патогенетичний механізм інтенсифікації уражень органів та тканин ротової порожнини.

Мета дослідження – на основі статистичних даних прослідкувати тенденцію поширеності потреби ортопедичного лікування повної відсутності зубів у мешканців Івано-Франківської області у період 2016–2020 років. Методи дослідження. Для реалізації мети дослі- дження нами проведено збір та аналіз офіційних статистичних даних щодо кількості пацієнтів, які звернулися по стоматологічну допомогу із потре- бою ортопедичного лікування повної відсутності зубів у лікувальні заклади Івано-Франківської області у період 2016–2020 років. Для визначення поширеності захворювання серед меш- канців Івано-Франківської області нами опрацьовані офіційні статистичні дані, надані Головним управлін- ням статистики в Івано-Франківській області, щодо розподілу постійного населення (18 років і старше), вікового та статевого складу населення Івано-Фран- ківської області у період 2016–2020 років. Наукова новизна. Вперше проведений збір та аналіз даних щодо поширеності повної відсутності зубів у мешканців Івано-Франківської області. На основі статистичних даних кількості пацієнтів, які зверну- лися у лікувальні заклади Івано-Франківської області з метою ортопедичного лікування повної відсутності зубів та чисельності населення області встановлено тенденцію розвитку патології мешканців Прикар- паття у період 2016–2020 років. Висновки. На основі статистичних даних зафік- совано тенденцію до росту поширеності потреби ортопедичного лікування повної відсутності зубів у мешканців Івано-Франківської області. Починаючи із 2016 року і до 2019 року спостерігався ріст кількості хворих із встановленим діагнозом «повна втрата зубів». 2020 рік став винятком – ймовірно зважаючи на карантинні обмеження. Встановлено перевагу осіб жіночої статі із встанов- леним діагнозом «повна втрата зубів» та визначено причини цієї переваги (вища чисельність постійного дорослого населення області та вищий рівень серед- ньої очікуваної тривалості життя в осіб жіночої статі Івано-Франківської області).

Мета дослідження – дослідити можливість комбіно- ваного використання PRF-згортку та випромінювання червоного спектру для покращення загоювання постек- стракційної рани у пацієнтів з цукровим діабетом . Методи дослідження. Дослідження по своїй організа- ції мало проспективний і порівняльний характер. Для дослідження були відібрані 2 групи пацієнтів. Група 1 (30 пацієнтів) – пацієнти, що хворіють на цукро- вий діабет, яким проводилось видалення зубів без застосування додаткового місцевого лікування, група 2 (30 пацієнтів) – пацієнти, що хворіють на цукровий діабет, яким проводилось видалення зубів, застосовува- лась фотонна терапія та внесення в лунку видаленого зуба PRF. Для оцінки клінічної ефективності запропо- нованого лікування проводили морфометричний аналіз. Наукова новизна. Використання PRF-згортку та випромінювання червоного спектру для оптимі- зації процесів регенерації в постекстракційній рані у пацієнтів на тлі цукрового діабету представляє інтерес як неінвазивний метод місцевого лікування. Висновки. В групі пацієнтів, яким проводилося місцеве лікування, виявлені морфологічні ознаки, які доказують прискорення процесів регенерації. А саме: під впливом фотонної терапії та PRF відбувалося зменшення від- носної площі стромального набряку, зменшення кіль- кості сегментоядерних лейкоцитів, покращення ангіо- генезу, оскільки більшою була кількість новоутворених судин та їх відносна площа, раніше появлялися макро- фаги та фібробласти, колагенові волокна та капіляри.

The effectiveness of insecticidal baits based on chlorfenapyr and hydramethylnone against colonies of the Pharaoh ant has been studied. Sugar baits containing 0.1–1.0 % chlorfenapyr are ineffective because after 4 weeks of the experiment, the viability of the colonies was not changed. Sugar baits based on 1 % hydramethylnon effectively destroyed workers, the effect on queens was weak, and depletion of the colony was achieved. Commercially produced baits effectively and completely destroy ant colonies both in the absence and in the presence of alternative food. Keywords: Pharaoh ant, baits, chlorfenapyr, hydramethylnon.

The article presents the results of a qualitative and quantitative analysis of the microbiome of places where dogs of service breeds are kept, obtained under the conditions of rotation of medicines for an active substance. In the period from 2017 to 2021, dynamic observations were made to assess the effectiveness of preventive disinfection measures carried out in the cynological town. The object of the study was the micro-and mycoflora of more than 20 dog enclosures in two versions: before disinfection and after mechanical treatment and fine-drip irrigation with preparations recommended for disinfection of veterinary surveillance facilities. Using differential diagnostic nutrient media, representatives of different groups of microorganisms were isolated from the surfaces of inventory, poilushki, the floor and walls of the walking enclosures. A qualitative analysis of biodiversity revealed that microbial isolates are conditionally pathogenic microorganisms and can be potentially dangerous infectious agents. The results showed that disinfection measures were not sufficiently effective against the selected groups of microorganisms. Using elective nutrient media, cultures of yeast-like and mold-like micromycetes were isolated from the surfaces of walking enclosures. The analysis of the data showed that both decompositions, claimed to be effective against mold micromycetes, do not withstand the contaminating load. The method of small-drop irrigation used for processing the walking of the kennels of the cynological town turned out to be low-effective in relation to the isolated microbial and fungal isolates. Within the framework of compliance with the sanitary and hygienic regime, an algorithm for organizing preventive disinfection measures in the cynological unit has been developed, based on the well-coordinated interaction of support services: medical, logistics, sanitary and veterinary. The research conducted jointly with representatives of the veterinary and sanitary service, with cadets of the cynological faculty, is of great practical importance for the formation of the professional competence of future officers – specialists-cynologists, heads of cynological units. The developed recommendations make it possible to adjust the algorithm of sanitary and hygienic measures in the cynological town and are of great importance in solving health-saving issues and maintaining the number of dogs of service breeds. Keywords: preventive disinfection; sanitary-indicative microorganisms; micromycetes; health care of dogs; cynologists.

The Moderating Role of Resource Accessibility to the TPB Components; A Study of E-entrepreneurship Intention among Saudi Women
Authors: Alzamel Samar
Published: September 2021

E-entrepreneurship has received significant attention in the 21st century as entrepreneurial activities anchor on creativity and innovation. Seeking to change from a petroleum-based to a service-based economy, the government of Saudi Arabia considers entrepreneurship as a critical option. This study investigates the influence of the TPB components (attitude towards entrepreneurship, subjective norms, and entrepreneurial self-efficacy) on the e-entrepreneurial intention of Saudi women. Five hundred thirty-four female undergraduate students from different universities in Saudi Arabia completed survey questionnaires to understand the moderating role of resource accessibility in influencing entrepreneurial intentions. Structural Equation Modeling (SEM) was used to test the model. The study reveals that attitude towards entrepreneurship and entrepreneurial self-efficacy are significantly related to e-entrepreneurial intention, while the subjective norm was insignificant. The moderation role of resource accessibility (RA) positively impacted the relationship between the TPB components and e-entrepreneurial intention. The findings of this study develop a base for supporting women's entrepreneurial intention through resource accessibility.

Antecedent of Organizational Change and Its' Consequnce towards Organizational Performance
Authors: Tua LG Lambas Marasi , Kurniawati Kurniawati
Published: September 2021

Even very successful organizations need to constantly change (evolve) due to very dynamic business environment conditions (Pangarkar, 2015). An organization needs to adapt to any changes in technology, economy, demographics, regulations, competition, and consumer preferences that change rapidly (Anyieni, 2016). Dynamic changes also constantly occur in the banking industry in Indonesia. As the central institution in driving economic growth, the bank needs to be more adaptive to changes in the business environment driven by customer expectations, technological capabilities, policies, demographics, and macroeconomic conditions. Over the last ten years, competitive pressures in the industry have put pressure on the level of banking profitability and efficiency issues (Source: SPI 2019, www.ojk.go.id). Barquin et al. (2018) also mentioned that technology development had brought a new competitive landscape in the banking industry. Technology has provided more convenience in terms of access to the financial services that also raise concern on the relevance of old-style banking services with high reliance on the conventional branch as access. As an impact of technology development change in financial services, increasing financial technology (fintech) services have emerged another competition platform in the banking industries in recent years. Digital technology will change the competition platform in the financial services industry. If banks are not ready to adapt to the change will be exposed to the shrinking market share (www. Economy.okezone.com, 2019). Fintech is expected to put more pressure on banking lending products, particularly within the retail banking segment, potentially will exist in 2025, as explained by McKinsey (www.keuangan.kontan.co.id, 2018). The commercial lending segment will expose to the competition due to technical support in terms of ease of access. Strong investor support to develop their market in Indonesia is expected to accelerate the change of competition landscape in the small-medium enterprise business (www.money.kompas.com, 2019).

Factors Affecting the Performance of Micro, Small and Medium Enterprises (MSMEs) in Indonesia during COVID 19 Pandemic
Authors: Wulandari Ririn , Koe Wei-Loon
Published: September 2021

Due to the Covid 19 pandemic, Indonesia's economic growth in the first quarter of 2020 has fallen to 2.97; it recorded -5.35 in the second quarter and -3.49 in the third quarter (Mulyani, 2020). This decline in growth has undoubtedly shaken micro, small and medium enterprises (MSMEs). According to the Ministry of Cooperatives for Micro, Small and Medium Enterprises (2020), 18.83% of MSMEs suffered hampered production, 22.9% experienced decreased demand, 18.87% faced difficulties in obtaining raw materials and 20.01% encountered hampered distribution. MSMEs in Indonesia contribute 60.4% of GDP and 97% of employment (Economic Indicator, 2019). However, they were severely affected by the Covid 19 pandemic. Therefore, examining the performance of MSMEs during the period of COVID 19 pandemic is crucial. Moreover, the pandemic has resulted chaotic economic conditions and changes in social order. Economic chaos and changes in social order could either strengthen or weaken the resilience of MSMEs. According to Tencer & Cadoso (2014), innovation arises because of chaos and unhealthy market domination. Ivanus & Repanovici (2016) mentioned that MSMEs need to have clear innovation strategy, adjust to market demand, make changes in production costs and show product quality in order to increase the economic growth. As supported by Christensen et al. (2018), MSMEs innovate to ensure their business continuity is maintained. Thus, innovation is particularly important for business survival in the era of Covid 19 pandemic. However, Martinez-Vergara and Vall-Pasola (2020) found that some businesses did not innovate. As such, there is a need to scrutinize further on the influence of business owners' characteristics on innovation and its effect on performance.

Authors: Hermawan Marko S , Burhanudin Burhanudin , Thoha Nurianna , Oscarin Irene
Published: September 2021

This paper investigates the SME's management control, human resources, and cultural context in Indonesia. These perspectives come into 2 (two) themes; Professional Capacity and Company Strategy. Most SMEs show a struggle in developing human quality and in particular, Indonesia's SMEs, also lack process controls due to their beliefs and cultures. Nonetheless, despite the positive impacts for the business sustainability that previous researchers have found, the implementation of MCS still has not been adequately done by the SME due to their several limitations. Thus, this paper aims to analyze a company perspective regarding the MCS implementation, specifically in the new phenomenon related to the contingent factors that arise from company issues and challenges using a case study from a clothing manufacturing company. The research question proposes for this research study is "How does Indonesia's SME implement its management control within limited resources and local culture?"

“POPULIST FOREIGN POLICY”: BARRIERS TO CONCEPTUALIZATION AND TYPOLOGIZATION
Authors: Shein S.A.
Published: September 2021

The “populist wave” in the EU member states is no longer a phenomenon isolated in domestic politics. It has a projection on the sphere of foreign policy of national states and the European Union. The article aims to “shed light” on the barriers arising on the way of conceptualizing and typologizing the foreign policy orientations of populist actors, relying on an ideological approach to populism. The study revealed that the main constraints for the conceptualization and typologization of populists' foreign policy are the fragmented nature of populism as an ideology, the limited ability to translate their attitudes into the political course, and gradual mainstreamization after coming to power.

Published: September 2021

Against the backdrop of Turkish-Russian cooperative rivalry – an ambiguous relationship fraught with strategic competition on the one hand, and driven by cooperation in key areas (energy, defence) on the other, the article surveys the growing interdependencies between Turkey and Ukraine and seeks to answer the question whether closer bonds – political and military – between these two countries could be seen as a strategy of soft balancing against Russia. On a broader level, the article speculates on the complex nature of Turkey-Russia relations, which have become increasingly volatile, transactional, opportunistic and compartmentalized.
Kierunki rozwoju globalnego klastra technologii i innowacji Greater Bay Area w Chinach – stan i perspektywy
Authors: Radomska Ewa
Published: September 2021

The purpose of this article is to describe the main directions for developing the global technology and innovation cluster Greater Bay Area (GBA) in China. Strengthening productivity and enhancing innovation have become focal points of the country’s next phase of economic growth. Under the conditions of the depleting traditional sources of growth and economic development in China, the initiatives aimed at the development of cluster structures play an important role in improving competitiveness, innovation and innovativeness of the economy. Among them, attention should be paid to the ambitious project to connect the major cities from the southern coast of China with Hong Kong and Macau into a cluster to provide an integrated economic and business centre of modern China. The main research question is: What are the opportunities and challenges in making the cluster concept at the initial stage of development a reality? A descriptive, comparative and analytical method has been used. The analysis has led to a few main conclusions. The GBA cluster has a great development potential. Creating a fully integrated region under the conditions of a collision between different legal, administrative systems and currency and business practices is a challenge. In order for a cluster to grow, it is essential to strengthen regional cooperation and to continue efforts to eliminate institutional and legal barriers in the region, to introduce incentives to encourage the establishment and development of cooperation between cluster participants, to provide reliable information and data on changes in the legal sphere and economic forecasts, and to create high quality local relationships to build and strengthen mutual partnership and trust.
CZTS polycrystal formation by laser annealing and demonstration of solar cell fabrication
Authors: Shimamune Yosuke , Inoue Shun , Jimbo Kazuo
Published: September 2021

Cu2ZnSnS4 (CZTS) is a promising material for solar cells because all its constituents are earth-abundant elements, and its light absorption coefficient is ∼100 times higher than that of Si. CZTS is generally formed by precursor formation followed by heat treatment at 400 °C–600 °C. In this work, a novel CZTS formation process, which consists of Cu-Zn-Sn-S containing CZTS precursor formation followed by 445 nm laser irradiation in atmosphere, is investigated. X-ray diffraction, Raman spectroscopy, scanning electron microscopy, and UV–vis spectroscopy analysis reveals that the poly crystallization of CZTS precursor is promoted by increasing the output power or scan time per unit length at the laser irradiation. This suggests that the defect or secondary phase reduces, and the precursor changes to CZTS polycrystal by laser annealing. Finally, a CZTS thin-film solar cell is fabricated through laser annealing, with an efficiency of 0.003% under AM1.5 G (100 mW cm−2) at 25 °C.
Türkçe-Arapça Dil İlişkilerine Tarihsel ve Güncel Bir Bakış: Mardin Arapçası Atasözleri Örneği
Authors: MUTLU Gamze
Published: September 2021

Anadolu coğrafyası, yüzyıllardır çeşitli medeniyetlere ev sahipliği yapmıştır. Bugün Türkiye Cumhuriyeti sınırları içerisinde bir yandan Anadolu kültürünün bir kolunu oluşturan, öte yandan tarihsel Mezopotamya kültürünü genlerinde taşıyarak devam ettiren Mardin; çeşitli dillerin iç içe geçmişliğine, yani dil katmanlaşmasına sahne olan yapısı ile oldukça dikkat çekici, aynı zamanda konuşulan dillerin birbirleriyle etkileşimini canlı olarak takip edebilme fırsatı sunduğu için de oldukça önemli bir dilbilimsel temas bölgesidir. Mardin Arapçası, Anadolu’da konuşulan diğer Arapça lehçelere, hatta modern Arap lehçelerine göre taşıdığı bazı arkaik dil özellikleri ile Fasih Arapçaya daha yakın olması ve baskın dil Türkçe ile çok yakın ve yoğun ilişkiler içerisinde olması dolayısı ile incelenmeye değerdir. Temelleri oldukça eskiye dayanan Türkçe-Arapça dil ilişkileri, bugün Mardin’de farklı bir boyutta ve seyirde devam etmektedir. Bu çalışmada, kalıplaşmış yapıları ile dilsel kodları ve kültürü muhafaza eden ve dilde var olan arkaik unsurları günümüze taşımada en ideal söz birlikleri olarak gördüğümüz atasözleri ekseninde Türkçe-Arapça dil ilişkilerinin günümüzdeki bu farklı boyutuna ve dildeki -şimdilik bu çalışma için kısmî- yansımalarına dikkat çekilecektir. Bu konuda; Türkçe-Arapça atasözleri odaklı yıllardır devam ettiğimiz karşılaştırmalı kaynak taramalarımız, derleme ve gözlemlerimiz neticesinde Türkiye Türkçesi yahut Anadolu ağızları ile kelimesi kelimesine aynı olan, aynı anlam ve bağlamda da kullanılabilen; ancak Mardin Merkez Arapçası özelinde daha geniş anlam ve bağlamlarda da kullanıldıklarını tespit ettiğimiz üç atasözü incelenerek konunun farklı ve örtük yönlerini ortaya çıkaran bulgular paylaşılacaktır.

In this review, we would like to present some of the most interesting modern designs of walking robots: bipedal, quadropedal, hexopedal, and octopods. Their advantages and disadvantages are highlighted. It has been determined that structures with eight or more limbs are ineffective due to high level of electricity consumption. The use of more than six number of legs does not give noticeable advantages in profile cross-country ability or maneuverability, however, it allows to reduce the forces and moments of inertia forces due to decrease in mode coefficient (ratio of time spent by propulsor in support to time of entire step), and, consequently, smoother leg movements in swing phase.
Coordinated Cooperative Distributed Decision-Making using Synchronization of Local Plans
Authors: Kloock Maximilian , Alrifaee Bassam
Published: September 2021

Centralized decision-making for a Networked Control System (NCS) suffers from a high computational burden on the planning agent. Distributed agents, which compute cooperative decision-making, increase computational performance. In cooperative decision-making, agents locally plan for a subset of all agents. Due to only local system knowledge of the agents, these local plans are inconsistent with the local plans of other agents. This inconsistency leads to the infeasibility of plans. This article introduces an algorithm for synchronizing local plans for cooperative distributed decision-making. The algorithm enables parallel decision-making and achieves feasible decisions. The algorithm consists of two iterative steps: local planning and global synchronization. In the local planning step, the agents parallelly compute local decisions, referred to as plans. Subsequently, consistency of the local plans across agents is achieved using global synchronization. The globally synchronized plans act as reference decisions for the local planning step in the next iteration. In each iteration, the local planning guarantees locally feasible plans, while the synchronization guarantees globally consistent plans in that iteration. The parallel algorithm converges to globally feasible decisions if the coupling topology is feasible. We introduce requirements for the coupling topology to achieve convergence to globally feasible decisions and present the algorithm using a model predictive control example. Our evaluations with car-like robots show that globally feasible decisions are achieved.

By their very nature, Spin Waves (SWs) consume ultra-low amounts of energy, which makes them suitable for ultra-low energy consumption applications. In addition, a compressor can be utilized to further reduce the energy consumption and enhance the speed of a multiplier. Therefore, we propose a novel energy efficient SW based 4-2 compressor consisting of 4 XOR gates and 2 Majority gates. The proposed compressor is validated by means of micromagnetic simulations and compared with the state-of-the-art SW, 22nm CMOS, Magnetic Tunnel Junction (MTJ), Domain Wall Motion (DWM), and Spin-CMOS technologies. The performance evaluation shows that the proposed compressor consumes 2.5x less and 1.25x less energy than the 22nm CMOS and the conventional SW compressor, respectively, whereas it consumes at least 3 orders of magnitude less energy than the MTJ, DWM, and Spin-CMOS designs. Furthermore, the compressor achieves the smallest chip real-estate. In summary, the performance evaluation of our proposed compressor shows that the SW technology has the potential to progress the state-of-the-art circuit design in terms of energy consumption and scalability.

The aim: To optimize diagnostic of pathological processes in lungs affected by COVID-19, dynamic monitoring and clinical decision making using lung ultrasound in limited resources settings.
Materials and methods: Between the onset of pandemics and January 2021, approximately 9000 patients have been treated for confirmed COVID-19 in the Olexandrivska Clinical Hospital. Assessment of all hospitalized patients included hematology, chemistries and proinflammatory cytokines – IL-6, CRP, procalcitonin, ferritin. Diagnosis was confirmed by PCR for SARS-CoV-2 RNA. Chest X-ray was performed in all hospitalized cases, while CT was available approximately in 30% of cases during hospital stay. Lung ultrasound was proactively utilized to assess the type and extent of lung damage and to monitor the progress of disease in patients hospitalized into the ICU and Infection Unit (n=135). Ultrasound findings were recorded numerically based on scales.
Results: In the setting of СOVID-19, bedside lung ultrasound has been promptly recognized as a tool to diagnose and monitor the nature and extent of lung injury. Lung ultrasound is a real time assessment, which helps determine the nature of a pathologic process affecting lungs. In this paper the accuracy of bedside LUS, chest X-ray and computer tomography are compared based on clinical cases, typical for COVID-19 lung ultrasound appearance is evaluated. Described in article data is collected in one of the biggest facility that deals with COVID-19. Chest X-ray was performed in all hospitalized cases, while CT was available approximately in 30% of cases during hospital stay. The cases presented in the paper indicate potential advantages to the use of ultrasound in limited resource healthcare settings, especially when the risk of transportation to CT outweighs the value of information obtained.
Conclusions: Grading of ultrasonographic findings in the lungs was sufficient for both initial assessment with identification of high risk patients, and routine daily monitoring. Hence, lung ultrsound may be used to predict deterioration, stratify risks and make clinical decisions.

The aim: Improve the treatment outcomes of patients with fluid collections following acute pancreatitis using an ultrasound-guided puncture and catheter drainage methods.
Materials and methods: 67 patients with acute pancreatitis complicated by fluid collections were divided into two groups. The first group (comparison group) consisted of 32 patients who underwent percutaneous ultrasound-guided puncture and catheter drainage interventions in addition to conservative therapy. The second group (control group) consisted of 35 patients receiving conservative therapy. The age of patients was from 18 to 77 years. In the comparison group among 32 patients there were 19 women and 13 men, the average age consisted 48.2 ± 2.2 years. In the control group among 35 patients there were 21 women and 14 men, the average age of patients consisted 47.1 ± 2.3 years.
Results: The mortality rate in the comparison group was 2 (6.2%) cases, in the control group – 4 (11.4%) cases (p <0.05). Infection of fluid collections developed in 2 (6.2%) patients of the comparison group and in 5 (14.3%) patients of the control group. The average length of stay in the hospital of patients in the comparison group was 24.13 ± 2.17 days, in the control group 28.11 ± 1.05 days (p <0.05). Also in the comparison group there was a faster normalization of clinical and laboratory indicators (level of leukocytes, serum amylase, C-reactive protein) (p <0,05).
Conclusions: the use of percutaneous ultrasound-guided puncture and catheter drainage methods has reduced mortality and improved treatment outcomes in patients with acute pancreatitis complicated by fluid collections

The aim: Gamma-glutamyl transferase (GGT) is a membrane-dependent enzyme and is primarily involved in glutathione metabolism. While a correlation between high GGT levels and oxidative stress, cardiovascular diseases, and some cancers has been shown in the literature, its prognostic effect in patients with non-small-cell lung cancer remains unclear. The aim of this study was to investigate the correlation between the preoperative GGT levels and the prognosis of non-small-cell lung cancers treated surgically.
Materials and methods: Following the approval of the loc al ethics committee, the medical records of patients surgically treated in our department for stage-I non-small-cell lung cancer between January 2010 and December 2019 were retrospectively reviewed. The patients were classified into a high group (high-GGT) and low group (low-GGT) according to the preoperative GGT cut-off levels, which were specific to our series and calculated by receiver operating characteristic (ROC) analysis. Survival differences between the groups were also investigated by Kaplan-Meier, log-rank, and Cox regression tests.
Results: A total of 219 patients fulfilled the inclusion criteria and were included in the study. The median survival was 75 (range: 58.4–91.1) months in the high-GGT group and 91 (range: 85–96.8) months in the low-GGT group, and this difference was statistically significant (Hazard Ratio: 2.0, 95% CI 1.0-3.9, p = 0.03).
Conclusions: Preoperative GGT may be an inexpensive and easily applicable prognostic indicator in early-stage non-small-cell lung cancers.

The aim: To study the microscopic, ultramicroscopic, and histomorphometric features of the knee articular cartilage in rats with an extra-articular injury of the femur and tibia.
Materials and methods: 60 white laboratory rats divided into three groups (I – control; II – animals with traumatic femur injury; III – animals with traumatic tibia injury) were used for the study. The light microscopy was performed by Olympus BH-2 microscope (Japan), transmission electron microscopy – by JEM-1230 microscope (Japan). SPSS software (version 17.0) was used for mathematical analysis.
Results: The more pronounced morphological changes were observed in the articular cartilage of the proximal tibial epiphysis after mechanical tibial injury. The thickness of the articular cartilage was 27.89 % less than in the control. The chondrocyte number in the superficial zone was lower by 8.94 %, intermediate zone – by 14.23 %, and deep zone – by 21.83%, compared to control. Herewith, the histological changes were mostly detected in the intermediate and deep zones of the articular cartilage of both bones. Also, some chondrocytes had deformed nuclei, hypertrophied organelles, numerous inclusions, and residual glycogen granules.
Conclusion: The extra-articular mechanical trauma of the lower limb bones leads to pathological changes in the knee articular cartilage. The structural changes include the articular cartilage thickening, the decrease in chondrocyte number, as well as chondrocyte rearrangement due to degenerative-dystrophic processes.

The aim is to study the level of insulin-like growth factor-1 (IGF-1) and insulin-like growth factor-2 (IGF-2) in the blood serum of patients with papillary thyroid cancer, depending on the main clinical and morphological features of the disease.
Materials and methods: The material was the information about 60 patients with papillary thyroid cancer (group 1). In group 2 there were 10 patients without oncopathology. All patients underwent clinical examination after total thyroidectomy before special treatment (radioiodine therapy): ultrasound diagnosis of the neck, confirmed diagnosis of papillary thyroid cancer by morphological examination of operative material. All patients underwent anthropometric studies (height, weight), on the basis of which the body mass index (BMI) was calculated. The study program also included determination of the level of thyroid-stimulating hormone of the pituitary gland (TSH), thyroglobulin (TG), antibodies to thyroglobulin (AB-TG). It was also determined the serum glucose level. In order to assess insulin resistance, the HOMA-IR index was calculated. All patients were tested for serum IGF-1 and IGF-2.
Results: In the blood serum of patients with papillary thyroid cancer in 63% of patients the level of IGF-1 and in 85% – IGF-2 was probably higher than in the control group. There is a relationship between the level of IGF-1, IGF-2 and elevated level of proliferating factor – insulin in the serum of patients with papillary thyroid cancer. This may indicate an aggressive potential of the disease (i.e. clinical data on the prevalence of papillary thyroid cancer coincide with laboratory data). There was found a relationship between the expression of IGF-1, IGF-2 and insulin: at elevated levels of insulin> 24.9 μIU/ml, IGF-1 increases 4.2 times, and IGF-2 – 2.5 times. Evaluation of the relationship between the level of IGF-1 and IGF-2 and cervical lymph node involvement shows that in the absence of lesion (N0) there is an increase in these indicators by 2.2 and 1.8 times, respectively.
Conclusions: The signaling system of insulin-like growth factors (IGF-1 and IGF-2) plays an important role in the occurrence and progression of malignant tumors. It is especially true for papillary thyroid cancer, so its components can be considered as potential diagnostic and prognostic markers of the disease and targets for anticancer therapy.
