The technology for the production of high-quality concrete products includes the vibration of the concrete mixture at various frequencies. For this, an electromagnetic vibration drive can be used, which has high reliability, durability and controllability. For its effective application, it is necessary to adjust the resonance frequency of the oscillating system in order to ensure the near-resonance mode of operation at different frequencies. This is possible by using devices with adjustable stiffness, in particular, controlled dynamic vibration absorbers with nonlinear elastic elements. In the article the electromagnetic, electromechanical, mechanical, and energy processes in a controlled vibration system, which includes an electromagnetic vibrator and a vibration absorber with conical springs, the stiffness of which is regulated by compression using a press, have been investigated. Using the circle-field method, a mathematical and simulation model of electromagnetic and electromechanical processes in the vibrator has been developed. For this purpose, numerical calculations of the magnetic field in the vibrator have been performed and, based on the obtained results, the functional dependences between the electromagnetic force, magnetic flux, magnetomotive force and the size of the air gap have been determined. A model of the mechanics of the oscillating system, processes in the vibration absorber press drive and processes in the control system has been also developed. The built simulation models were combined into a general model in the Simulink environment, by means of which the time diagrams of the processes have been obtained. The modeling results show that the system provides a smooth transition from one vibration frequency to another while maintaining the specified amplitude of the working body oscillations and near-resonance mode with high energy efficiency.

To determine the mutually agreed parameters of the output link of the generator of short (~100 ns) pulses with a working chamber, in which water is treated in the droplet-film state by a pulsed barrier discharge, an approximate mathematical model was developed that describes the transient processes in the circuit. The reliability of the model is confirmed by experimental data. The optimal parameters of the capacitance of the dielectric barrier and magnetic keys were calculated, according to which the efficiency of energy transfer to the working chamber reaches 62%. It is shown that it largely depends on the ratio of the barrier capacity of the working chamber to the output capacity of the pulse generator, the optimal value of which is ≈2.6. The selection of the value of the dissipation inductance of the magnetic key, through which the discharge of the barrier capacity occurs after the end of the direct current pulse, is justified. It was established that the consistency of the parameters of the output link of the pulse generator and the working chamber makes it possible to significantly reduce the thermal load on the fast-acting opening diode in the output link of the pulse generator.

The article reports distribution data on a rare fungus Chlorophyllum agaricoides (Agaricales, Basidiomycota) in Ukraine. This species has secotioid fruiting bodies as a result of adaptation of agaricoid fungi to arid environmental conditions. Chlorophyllum agaricoides is on the Red Lists of fungi in several European countries. In Ukraine, it is known from the following regions: Central (Right Bank) Polissya; Right Bank and Kharkiv Forest-Steppe; Donetsk, Right Bank, Left Bank, and Starobilsk Grass-Meadow Steppe; Right Bank and Left Bank Grass Steppe. New records from Dnipropetrovsk, Donetsk, Kherson, Mykolaiv, and Poltava regions were provided mainly by members of the Facebook group Fungi of Ukraine and added to the list of previously known localities of the fungus. Despite the increased number of finds, C. agaricoides remains a very rare species in Ukraine. Therefore, this species is proposed to be included in the Red Data Book of Ukraine and the need of searching for its new localities is emphasized.

Published: June 2023

New records of Tulipa suaveolens (incl. T. schrenkii: Liliaceae) in Odesa Region are reported. During 2017–2021, 23 localities of T. suaveolens with an area from 1.5 m2 to 730 m2 were found along 5.4 km of the right-bank slopes of the Kuyalnyk Estuary. The total area of all localities was 3458 m2 with a maximum plant density of 78 individuals per 1 m2. Almost all plants had yellow flowers; in some localities, there were plants with other perianth colors, but their number did not exceed 20 %. Based on the original and published data, it is demonstrated that the modern western border of the species range is located along the slopes of the Kuyalnyk Estuary. It has been established that the most negative impact on the steppe vegetation and plants of this tulip species is caused by insufficient precipitation. In particularly dry years (2019, 2020), most plants remained dormant. The habitats of T. suaveolens in the studied area are subject to significant anthropogenic influence and require specific protection measures.

Published: June 2023

In this article we prove sharp Landau-Kolmogorov type inequalities on a class of charges defined on Lebesgue measurable subsets of a cone in $\mathbb{R}^d$, $d\geqslant 1$, that are absolutely continuous with respect to the Lebesgue measure. In addition we solve the Stechkin problem of approximation of the Radon-Nikodym derivative of such charges by bounded operators and two related problems. As an application, we also solve these extremal problems on classes of essentially bounded functions $f$ such that their distributional partial derivative $\frac{\partial ^d f}{\partial x_1\ldots\partial x_d}$ belongs to the Sobolev space $W^{1,\infty}$.

Late antique Mediterranean rotary keys from Avaria
Authors: Bollók Ádám
Published: June 2023

The present paper describes and discusses a group of iron and copper-alloy rotary keys characterised by a moveable joint connecting the shaft and the key-ring, appearing in the seventh-century material record of the Carpathian Basin whose origins can be sought in the Mediterranean. While the few published examples of the class were in previous studies mainly regarded as Roman-period artefacts secondarily re-used as amulets by the Avar-period population of the Carpathian Basin, the present study argues that these pieces in fact have a sixth-to seventh-century production date, being thereby contemporaneous with their deposition in seventh-century mortuary assemblages. Taking this observation as a springboard for further interpretation, an overview of the possible meanings and symbolic associations attached to keys in Roman, late antique, and early medieval times is offered. The main argument presented here is that besides serving amuletic purposes, some of the Avar-period keys could in all probability have conveyed more explicit messages about their owners, such as that of their feminity and of their economic role and authority in their respective households. The Appendix supplementing the present paper seeks to provide a theoretical reconstruction of a wooden casket buried with the woman interred in Grave 119 of the Kölked-Feketekapu B cemetery, one of the burials yielding a Mediterranean hinged rotary key.
Gambling participation among Connecticut adolescents from 2007 to 2019: Potential risk and protective factors
Authors: Stefanovics Elina A. , Gueorguieva Ralitza , Zhai Zu Wei , Potenza Marc N.
Published: June 2023

Background and aims

Gambling in adolescents is a public health concern. This study sought to examine patterns of gambling among Connecticut high-school students using seven representative samples covering a 12-year period.

Methods

Data were analyzed from N = 14,401 participants in cross-sectional surveys conducted every two years based on random sampling from schools in the state of Connecticut. Anonymous self-completed questionnaires included socio-demographic data, current substance use, social support, and traumatic experiences at school. Chi-square tests were used to compare socio-demographic characteristics between gambling and non-gambling groups. Logistic regressions were used to assess changes in the prevalence of gambling over time and effects of potential risk factors on the prevalence, adjusted for age, sex, and race.

Results

Overall, the prevalence of gambling largely decreased from 2007 to 2019, although the pattern was not linear. After steadily declining from 2007 to 2017, 2019 was associated with increased rates of gambling participation. Consistent statistical predictors of gambling were male gender, older age, alcohol and marijuana use, higher levels of traumatic experiences at school, depression, and low levels of social support.

Discussion and conclusion

Among adolescents, older males may be particularly vulnerable to gambling that relates importantly to substance use, trauma, affective concerns, and poor support. Although gambling participation appears to have declined, the recent increase in 2019 that coincides with increased sports gambling advertisements, media coverage and availability warrants further study. Our findings suggest the importance of developing school-based social support programs that may help reduce adolescent gambling.
Who makes in-play bets? Investigating the demographics, psychological characteristics, and gambling-related harms of in-play sports bettors
Authors: Vieira Jenna L. , Coelho Sophie G. , Snaychuk Lindsey A. , Parmar Puneet K. , Keough Matthew T. , Kim Hyoun S.
Published: June 2023

Background and aims

Sports betting has increased markedly in recent years, in part due to legislative changes and the introduction of novel forms of sports betting (e.g., in-play betting). Some evidence suggests that in-play betting is more harmful than other types of sports betting (i.e., traditional and single-event). However, existing research on in-play sports betting has been limited in scope. To address this gap, the present study examined the extent to which demographic, psychological, and gambling-related constructs (e.g., harms) are endorsed by in-play sports bettors relative to single-event and traditional sports bettors.

Methods

Sports bettors (N = 920) aged 18+ from Ontario, Canada completed an online survey containing self-report measures of demographic, psychological, and gambling-related variables. Participants were classified as either in-play (n = 223), single-event (n = 533), or traditional bettors (n = 164) based on their sports betting engagement.

Results

In-play sports bettors reported higher problem gambling severity, endorsed greater gambling-related harms across several domains, and reported greater mental health and substance use difficulties compared to single-event and traditional sports bettors. There were generally no differences between single-event and traditional sports bettors.

Discussion

Results provide empirical support for the potential harms associated with in-play sports betting and inform our understanding of who may be at risk for increased harms associated with in-play betting.

Conclusions

Findings may be important for the development of public health and responsible gambling initiatives to reduce the potential harms of in-play betting, particularly as many jurisdictions globally move towards legalization of sports betting.

Bevezetés: A probiotikumok az Egészségügyi Világszervezet
meghatározása szerint: „Élő, speciálisan kiválasztott, a bél szempontjából
releváns mikroorganizmusok, amelyek fogyasztása megfelelő mennyiségben, a
hagyományos tápanyagokat meghaladó mértékben gyakorolnak jótékony hatást az
egészségre.” A jótékony baktériumok feladata a normálbélflóra egyensúlyának
fenntartása és a patogén baktériumok elszaporodásának megelőzése. A szájüregi
egészség megőrzésére egyre gyakrabban ajánlják a probiotikumok terápiás
alkalmazását. Az irodalom számos sikeres eredményről számol be, elsősorban a
fogszuvasodás és a fogágybetegség probiotikummal történő kezelésével
kapcsolatosan. Ezen esetekben a probiotikumok a betegséget kialakító
baktériumflórára vannak hatással. Saját kutatásunk során a caries és az 1-es
típusú diabetes esetén kialakult szájflóra esetleges eltéréseit vizsgáljuk.
Célkitűzés: A témával kapcsolatos irodalom összefoglalása
mellett célunk saját eddigi vizsgálatainkat bemutatni; összehasonlítani a
cariesmentes és a carieses, illetve az 1-es típusú diabetesszel élő és az
egészséges gyermekek szájflóráját; vizsgálni az összcsíraszámot, a
Lactobacillusok öszcsíraszámát, illetve ezek speciesszintű
összetételét. Módszer: A résztvevőktől (20 fő/csoport) 0,5 ml
nyugalmi nyálminta gyűjtése. Az összcsíraszám meghatározását véres táptalajon, a
Lactobacillusok tenyésztését Rogosa agaron végeztük. A
Lactobacillusok speciesszintű azonosítására speciális
tömegspektrométert alkalmaztunk. Eredmények: Az összcsíraszám
tekintetében a két vizsgálati csoport eredményei az adott kontrollcsoportok
eredményeihez képest nem mutattak szignifikáns különbséget (109
vs. 108 CFU/ml). Ezzel szemben mind a carieses, mind
a diabetesszel élő gyermekek csoportjában szignifikáns eltérést tapasztaltunk a
Lactobacillus-összcsíraszámban a kontrollcsoportokhoz
képest (102
vs. 103 CFU/ml). A Lactobacillusok
kvalitatív összetétele mindegyik vizsgálati csoportban különbözött.
Megbeszélés: A caryogen szájflóra kiszoríthatja a
probiotikus törzseket, ez a szájüreg normálflórájának felborulását okozhatja. Az
1-es típusú diabetes gyermekkorban is hatással lehet az orális flóra
összetételére. Következtetés: A szájüreg normálflórájának
probiotikumokkal történő helyreállítása egy lehetséges prevenciós út a szájüregi
kórképek kialakulása szempontjából. Az egyes probiotikumtörzsek működésének
részletesebb vizsgálata további kutatások részét kell, hogy képezze. Orv Hetil.

Authors:   Cairo University, Faculty of Veterinary Medicine, Department of Internal Medicine and Infectious Diseases, Giza, Egypt, Ghanem Yehia Shimaa
Published: June 2023

The objective of this study was to determine the activities of lactate dehydrogenase (LDH), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in the milk and blood of lactating Holstein cows and investigate their association with subclinical mastitis (SCM). This study also aims to evaluate the impact of SCM and its severity based on California mastitis test (CMT) scores on the above mentioned enzymes, as well as to test the efficiency of their use as an early predictive diagnostic tool. Thirty multiparous, lactating dairy Holstein cows were examined using CMT and according to the obtained results classified into four groups; control group 1 (SCM-free = 10, score = 0), group 2 (weak positive = 8, score +1), group 3 (positive = 7, score +2) and group 4 (strong positive = 5, score +3). The milk LDH, ALP, and GGT activities were significantly higher in groups 3 and 4 compared to group 2 and the control group. LDH activity was significantly higher in group 2 compared to the control group. The mean blood LDH and ALP activities in SCM groups were significantly higher than in the control group. ALP blood activity was significantly higher in group 4 compared to group 2. The blood GGT activity was significantly higher in group 4 compared to other groups. There was a significant positive association between milk LDH, ALP, and GGT enzymes as well as the blood enzymes (ALP and GGT) in SCM cows. The results showed that subclinical mastitis causes considerable changes in the activities of enzymes in milk and blood of infected cows.

Authors:   Hatay Mustafa Kemal University, Faculty of Veterinary Medicine, Department of Biostatistics, TR-31060 Hatay, Türkiye, Kaya Ufuk
Published: June 2023

The aims of this study were to establish a cut-off point by evaluating the usability of the somatic cell count (SCC) and milk components (fat, fat-free dry matter (FFDM), protein, lactose, freezing point, electrical conductivity and pH) to observe the pregnancy status, and to determine the practical usage of these parameters as diagnostic biomarker of pregnancy status. In the present study, primiparous Holstein cows (n=133) were included in the mid and late lactation. Milk samples were collected in sterile tubes for SCC and milk components analysis. In each lactation period, SCC, milk yield and milk component parameters were analysed by Student's t test according to pregnancy status. Receiver operating characteristic curves were used to determine the predictive threshold using SCC and milk component parameters to discriminate between pregnant and non-pregnant cows. SCC levels were similar for all cows in the mid and late-lactation. In the mid lactation, FFDM, protein, lactose and electrical conductivity were higher and milk yield, fat, freezing point and pH were lower in pregnant cows (p<0.05). In the late lactation, FFDM, protein, lactose and electrical conductivity were significantly higher and milk yield, fat and pH were significantly lower in pregnant cows (p<0.05). Furthermore, fat, FFDM, protein, lactose, freezing point, electrical conductivity, and pH were the best predictors for pregnancy diagnosis in mid-lactating cows with the AUC values of 0.840, 0.768, 0.780, 0.772, 0.693, 0.792, and 0.901 respectively. Furthermore, fat, FFDM, protein, lactose, electrical conductivity, and pH could be useful diagnostic tools for pregnancy determination in late lactating cows with the AUC values of 0.869, 0.684, 0.661, 0.689, 0.756, and 0.841 respectively. In conclusion, the milk components could be used as rapid, easily accessible, and inexpensive markers for the evaluation of the diagnosis of pregnancy status in primiparous Holstein cows.
Quality indices of ice cream produced from dairy milk partially substituted with Bambara groundnut (Vigna subterranean (L)Verdc.) beverage

Published: June 2023

The most important ingredient in ice cream production is milk. However, keeping the body, structure, and texture of ice cream requires maintaining the right balance of various constituent ingredients. Recently, a number of plant-based milk alternatives have emerged with reduced particle size distribution. Although Bambara groundnut milk (BGNM) beverage appears increasingly applicable in yoghurt production, there is paucity of relevant literature reporting its application in ice cream production. In order to supplement the existing information, this work investigated the quality indices of ice cream from dairy milk partially substituted with Bambara groundnut beverage. Different proportions of dairy milk and BGNM blended to produce ice cream involved seven formulations (100:0, 0:100, 90:10, 80:20, 70:30, 60:40 and 50:50, all v/v %). Quality indices measured included the antinutrients (phytic acid and tannins), physicochemical, microbial and sensory aspects. The obtained results showed that fat and ash content decreased with increased substitution of dairy milk, whereas the protein, carbohydrate, calcium, iron, potassium and magnesium contents increased with addition of Bambara groundnut. In addition to statistical differences that occurred across the samples (p<0.05) in most cases, with varying ranges from pH (5.20-6.61), overrun (11.00-73.50%), total solids (10.98-12.35%), viscosity (1.00-2.25 Pa.s), to total titratable acidity (0.05-0.11 g/100 mL). Besides the increased meltdown values, and the somewhat varying anti-nutrients (tannin = 0.32-2.64 mg/100 g; phytic acid = 2.97-63.85 mg/100 g), the total viable count ranged from 1.2 x 103 to 8.7 x 102 CFU/mL, while sensory characteristics had quite a number of resemblances (p>0.05) between some samples. This current work has demonstrated a desirable ice cream can be produced by partially substituting dairy milk with up to 30% Bambara groundnut extract.

Community welfare is a benchmark of various conditions that can represent a quality community life. It is undeniable that welfare in a comprehensive sense can be realized if certain economic conditions can be achieved, one of which is prosperity. Economic freedom is a framework in which principles compatible with the ideals of prosperity are implemented in economic institutions and processes. Important components in economic freedom such as size of government, legal system and property rights, sound money, freedom to trade internationally, and regulation have a significant influence on the welfare of the people of a country. This study aims to examine the effect of economic freedom on the welfare of the people in several countries with the Muslim majority population. By using unsupervised learning methods and decision tree algorithms in the classification, the experiment result found that 35% of countries with a majority Muslim population in the world were classified as Moderately Free.

THE STATE OF STANDARDIZATION OF POST-QUANTUM CRYPTO-ALGORITHMS AT THE GLOBAL LEVEL
Authors: Tsentseria Oleksandra , Hleha Kateryna , Matiyko Aleksandra , Samoilov Igor
Published: June 2023

Abstract. In the digital age, cryptography is widely used in various important systems such as financial, military and government ones, medical records etc.
The life of modern people is closely connected with the cryptography. We send messages via instant messengers without even considering in which way the security of communications and data is ensured. We buy things both online and transfer money with confidence in transaction security. The level of digitization of our society is constantly increasing, and the digital data needs a reliable protection, which makes cryptography a current topic.
Cryptographic systems ensure our security and the basic properties of information, such as privacy, integrity, availability.
However, with the beginning of the development of quantum computers, the field of cryptography has developed in a new direction. Quantum cryptography is a science that studies the methods of communication systems protection. It is based on the idea that patterns of quantum physics (physical properties described by the laws of quantum optics, quantum electrodynamics, or quantum field theory) are inviolable. The current state of development and usage of powerful quantum computers, as well as their mathematical and software, is strictly confidential and securely protected. Only clear-cut information about quantum computers and their usage in cryptography is provided.
NIST has announced an open competition to select quantum-resistant public-key cryptographic algorithms. After the third round, CRYSTALS-KYBER, CRYSTALS Dilithium, FALCON, and SPHINCS+ were proposed to be standardized. NIST has already recommended moving from the sizes of keys and algorithms that provide 80 security bits to the sizes of keys and algorithms that provide 112 or 128 security bits in order to protect against classic attacks.
Post-quantum cryptography, which with its complexities still requires a more detailed study, challenge science once more. However, it is unknown when the changes will occur and when the quantum era will begin, as well as what consequences they will have. It is only possible to predict how many advantages will have quantum calculations compared to usual, and how different the new quantum models will be from classic ones.

В 2022 році ці енергоблоки були однією з основних цілей ракетних атак з метою розбалансування енергосистеми. Аварійне відключення одних енергоблоків має компенсуватися потужністю інших, в протилежному випадку впроваджуються аварійні відключення електропостачання споживачів. Питання підвищення маневрових можливостей існуючих енергоблоків сьогодні стоїть вкрай гостро. Котлоагрегатам ТЕС притаманні зміни динамічних характеристик при зміні режиму їх роботи. Тому до систем регулювання висуваються підвищені вимоги до якості функціонування і запасів стійкості. Стаття містить аналіз сучасних розробок в області синтезу робастних і адаптивних систем регулювання інерційними контурами котлоагрегатів ТЕС. Розглянуті схеми регулювання з табличним підлаштуванням параметрів ПІ-регулятора, кусково-лінійною адаптацією, а також схеми з внутрішньою моделлю та з динамічним коректором. В якості об’єкта керування розглядається водопаровий тракт пиловугільного прямоточного котлоагрегату ТЕС потужністю 300 МВт. Параметри налаштування розглянутих схем розраховані за відомими методиками. Побудовані комп’ютерні моделі схем регулювання, на основі яких проведене моделювання їх роботи. Здійснений порівняльний аналіз показників якості їх функціонування. Розраховано запаси стійкості систем регулювання в усьому діапазоні робочих навантажень енергоблоку. Побудовані графіки залежності запасів стійкості за підсиленням і за фазою залежно від навантаження енергоблоку. Отримані результати зведені в підсумкову таблицю із зазначенням переваг і недоліків кожної з розглянутих схем.
Zamanın Ötesinde Geleneksellik ve Çağdaşlık Üzerine

Geleneksellik kavramı, toplumların yaşayış biçimlerini kurallara bağlayan, onları şekillendirerek insanlar arası ilişkileri düzene sokan kurallar bütünü olarak değerlendirilmiştir. Ancak bu kavramın ifade ettiği kapsamın bu denli dar olmadığını ortaya koyan çalışmalar yapılmış olsa da geleneksellik özellikle günümüz sanatında ötelenmiş hatta reddedilmiş bir konumda karşımıza çıkmaktadır.
Gelenekselliğin bu örselenmişliğinin ortadan kaldırılabilmesi için kavramın reddedilmesi değil, onun yapısal özelliklerindeki farklılaşmayla ortaya koydukları üzerinde durularak, daha doğru bir değerlendirme yapılması gerekmektedir. Sanatsal üretimlerde, gelenekselliğin toplumların yaşayış biçimini şekillendirdiği gerçeği ihmal edilerek bu kavramdan kaçınmak, yanılgıya düşülmesine neden olabilir.
Bu bağlamda sanatçının ekonomi, teknoloji, ticaret, siyaset ve kültür gibi olguların içerisinde yer almasından kaynaklanan etkilenmeleri sanatına yansıtmaması gibi bir durum söz konusu olamaz şeklindeki yorum yadsınamaz. Ülkemizde 1940 yılından itibaren yaygınlaşan geleneksel sanatlarımızdan yararlanma olgusu 1950’li yıllarda yoğun olarak devam etmiş ve 1980’lerden günümüze de yansımıştır. Araştırma kapsamında çağdaş Türk sanatçılarımızdan bu anlayışla çalışan Bedri Rahmi Eyüboğlu, Devrim Erbil, Süleyman Saim Tekcan, Nur Koçak ve Gülsün Karamustafa’nın sanat anlayışları genel bir çerçevede seçki yapılan eserleri ile birlikte geleneksellik, biçimsel yapısı ve kuramı ile değerlendirilmiştir. Bunula birlikte, geleneksellikten yararlanma yaklaşımı, Türk sanatçıların yanı sıra yabancı sanatçılardan Judy Chicago ve Takashi Murakami’nin eserlerinden birer seçkiyle de desteklenmiştir. Bu sanatçıların gelenekten ne şekilde yararlandıkları ve geleneği yansıtma biçimleri betimsel analizler yerine bilimsel araştırmalarla desteklenerek açıklanmıştır.
Geleneksellik ve çağdaşlık üzerine yapılan bu çalışma nitel araştırma yöntemi kullanılarak literatür taramasıyla yapılmış ve bazı sanatçı eser örneklemleri üzerinden çıkarımlara destek niteliğinde sonuca ulaşılmıştır. Sanatçı eser örnekleminin, sanatçıların yapıtlarında gelenekselliğin çağdaş sanatta yansımalarını kişisel üslupları ile bağımsız olarak uygulamalarının ve aktarımlarının devam edeceğinin bir göstergesi olduğu söylenebilir. Bu bağlam günümüzde geleneğin farklılığını okuyabilmek açısından oldukça önem taşımaktadır.

Published: June 2023

RESUMO Introdução: a cirurgia pediátrica representa especialidade com demanda significativa de encaminhamentos dos serviços de atenção primária para avaliação da necessidade de intervenção cirúrgica. Contudo, nem sempre o acesso a essa intervenção ocorre no momento adequado. Nesse sentido, objetivou-se caracterizar o perfil dos pacientes pediátricos operados eletivamente, no recorte temporal 2018-2020, e identificar pacientes que foram encaminhados em atraso para a avaliação com o cirurgião. Métodos: Estudo descritivo, transversal e retrospectivo mediante a revisão de prontuários eletrônicos. As variáveis avaliadas foram dados sociodemograficos, informações das doenças de base, dados do encaminhamento, da avaliação do especialista e do procedimento cirúrgico. Resultados: neste período 410 pacientes foram submetidos a procedimento cirúrgico eletivo, dos quais 289 foram incluídos na pesquisa. O sexo masculino (72,3%%) foi predominante, com idade média de 57,9 meses na avaliação pelo cirurgião e 59 meses na data da cirurgia. A procedência dos pacientes foi na maioria da atenção básica (75%) e a patologia mais incidente foi a hérnia inguinal (39,1%). O intervalo de tempo médio entre o encaminhamento pela atenção primária até a realização da cirurgia foi 4,98 meses e entre a avaliação pelo cirurgião e a realização da cirurgia foi 1,21 meses. Do total, 77 (26,6%) pacientes foram identificados como encaminhados em atraso para a realização do procedimento cirúrgico. Conclusão: conhecer o perfil dos pacientes e os problemas vivenciados nesta região em relação aos atendimentos prestados na cirurgia pediátrica apresenta subsídios para propor estratégias de melhoria não só do sistema de saúde local, mas de diversas regiões interioranas do Brasil em situação semelhante. .
As novas estratégias tecnológicas das multinacionais do setor das telecomunicações
Authors: MACULAN ANNE-MARIE
Published: June 2023

RESUMO O setor de equipamentos de telecomunicações é considerado um setor estratégico de alta tecnologia e precisa de grandes investimentos de longa data em P&D. Nas últimas três décadas, as estratégias tecnológicas das empresas multinacionais que controlam 80% do mercado mundial foram moldadas de acordo com dois padrões. Durante as décadas de 60 e 70, a administração pública de telecomunicações costumava selecionar a base técnica dos principais sistemas de equipamentos, financiar e realizar projetos de P&D em conjunto com empresas locais, para alocá-las às compras públicas. Isso permitiu fortalecer as empresas locais nos mercados nacional e internacional. Desde os anos 80, fusões e acordos tecnológicos geram um processo de concentração. As empresas japonesas e europeias intensificam seus investimentos diretos no mercado dos EUA. A concorrência cresce rapidamente no mercado desregulado de pequenos equipamentos.
Fatores aceleradores, mantenedores e sancionadores da inflação: um teste de evidência empírica para o Brasil
Authors: GUALDA NEIO LÚCIO PERES
Published: June 2023

RESUMO O objetivo deste artigo é testar empiricamente a formulação teórica do artigo de Bresser-Pereira & Nakano, “Os fatores de aceleração, mantenedores e sancionadores da inflação” (1984). O teste empírico suporta os resultados do seu estudo teórico. Destaca-se o papel do conflito distributivo como fator de manutenção no processo inflacionário, uma vez que a inflação passada cria forte rigidez descendente dos preços. Outra hipótese que se mostrou consistente refere-se ao caráter do dinheiro, pois representa uma variável endógena no sistema.

Objective: to identify the factors associated with antiretroviral therapy abandonment among adolescents and young people living with HIV/AIDS during the COVID-19 pandemic. Method: a case-control study carried out between 2020 and 2021 in Maringá, Paraná. The cases corresponded to the following: adolescents and young people (aged from 10 to 24 years old) diagnosed with HIV/AIDS and who abandoned treatment, while the Control Group consisted of people with similar sociodemographic characteristics, diagnosed with HIV/AIDS and with no history of treatment abandonment. Pairing of the cases and controls was by convenience, with four controls for each case. The research instrument presented sociodemographic variables, clinical characteristics and others, whose association with treatment abandonment was analyzed by means of logistic regression. Results: a total of 27 cases and 109 controls were included in the study (1/4 ratio). The variable associated with an increased chance of abandonment was age close to 22.8 years old (ORadj: 1.47; 95% CI: 1.07-2.13; p=0.024). Sporadic condom use (ORadj: 0.22; 95% CI: 0.07-0.59; p=0.003) and having an opportunistic infection (OR: 0.31; 95% CI: 0.10-0.90; p=0.030) were protective factors. Conclusion: age close to 23 years old at the last consultation was associated with antiretroviral therapy abandonment. The presence of opportunistic infections and condom use are determining factors for treatment continuity during COVID-19.

Objective: to analyze the effects of educational technologies in the prevention and treatment of diabetic ulcers. Method: a systematic review conducted in seven databases, a bibliographic index, an electronic library and the Gray Literature. The sample consisted of 11 randomized controlled clinical trials. The synthesis of the results was descriptive and through meta-analysis. Results: the predominant educational technologies were training sessions and verbal guidelines, with soft-hard technologies standing out. When compared to usual care, the educational technologies presented a protective factor to prevent the incidence of diabetic ulcers (RR=0.40; 95% CI=0.18-0.90; p=0.03) and the certainty of the evidence assessment was low. The educational technologies also had a protective factor to prevent the incidence of lower limb amputations (RR=0.53; 95% CI=0.31-0.90; p=0.02) and certainty of the evidence was very low. Conclusion: soft-hard educational technologies such as structured verbal guidelines, educational games, lectures, theoretical-practical training sessions, educational videos, folders, serial albums and playful drawings, and hard technologies such as therapeutic footwear, insoles, infrared digital thermometer, foot care kits, Telemedicine app and mobile phone use, were effective for the prevention and treatment of diabetic ulcers, although more robust studies are required.

Objetivo: evaluar la efectividad de la auriculoterapia para reducir el dolor musculoesquelético crónico de la columna vertebral de los trabajadores de la salud. Método: ensayo clínico aleatorizado, triple ciego, realizado con trabajadores de la salud diagnosticados con dolor crónico en la columna vertebral. Se aplicaron ocho sesiones de auriculoterapia con semillas, dos por semana. Los resultados fueron medidos con la Escala Numérica del Dolor, el Inventario Breve del Dolor, el Cuestionario de Discapacidad de Roland-Morris y los instrumentos SF-36, en la 1.ª, 4.ª, 8.ª sesión y follow-up a los 15 días. Análisis descriptivo e inferencial. Resultados: participaron 34 trabajadores del grupo intervención y 33 del grupo control, ambos mostraron una reducción en la intensidad del dolor (p>0,05). En el follow-up se registró una mayor reducción en el grupo intervención (3,32 ± 0,42) que en el grupo control (5,00 ± 0,43) (p=0,007). En cuanto a la calidad de vida, mejoró la vitalidad (p=0,012) y la limitación por aspectos emocionales (p=0,025). La relación entre auriculoterapia, discapacidad física e interferencia del dolor no difirió entre los grupos (p>0,05). El uso de medicamentos en el follow-up se mantuvo en el grupo control (77,8%) con respecto al grupo intervención (22,2%) (p=0,013). Conclusión: la auriculoterapia tuvo el mismo efecto en ambos grupos sobre la intensidad del dolor y duró más en el follow-up. Hubo una mejora en la calidad de vida y una reducción en el consumo de medicamentos. REBEC: RBR-3jvmdn.

Resumo Objetivos: identificar variáveis associadas à presença de acompanhante na sala de parto e sua associação com o aleitamento materno (AM) na primeira hora de vida. Métodos: análise transversal de dados provenientes de um estudo de coorte (n=344). Para investigação dos fatores associados entre a presença de companhia durante o parto e o AM na primeira hora foram realizadas análises de regressão de Poisson, considerando p<0,05 como nível de significância estatística. Resultados: 93,9% das parturientes tiveram acompanhante na sala de parto, não sendo encontrada associação entre características socioeconômicas, obstétricas e neonatais do binômio mãe-filho e esta presença. Em análise univariada, a ausência de acompanhante reduziu a frequência de AM na primeira hora (RP=0,64; IC95%=0,42-0,96), resultado que não se confirmou nas análises ajustadas (RP=0,79; IC95%=0,54-1,15). Secundariamente, identificou-se que o Apgar no quinto minuto associou-se com AM na primeira hora (RP=1,27; IC95%=1,14-1,40) independentemente dos demais fatores. Conclusões: a maioria das mulheres da coorte contou com acompanhante na sala de parto, sem diferenças segundo variáveis socioeconômicas, obstétricas e neonatais. A frequência de AM na primeira hora também foi alta e menor na ausência de acompanhante, contudo, essa associação não se mostrou independente de outros fatores.
