Elektriksel Kas Uyarımı Antrenmanının Sedanter Kadınlarda Vücut Kompozisyonu, Denge ve Sıçramaya Etkisi
Authors: PANCAR Serkan , ÖCAL Tuncay
Published: March 2023

Bu araştırmanın amacı, sedanter kadınlarda 6 haftalık EMS ile kombine olarak yapılan yüksek şiddetli egzersizlerin fiziksel performansa etkilerini incelenmesidir. Araştırma, deney (TV-EMS) (yaş = 25,6  1,26 yıl, n=10) ve kontrol grubu (yaş = 25,6  1,26 yıl, n=10) grubu olmak üzere 20 genç gönüllü kadın üzerinde gerçekleştirilmiştir. Çalışmada, deney grubu toplamda 18 seans (3seans/6 hft) 20 dakikalık tüm vücut EMS egzersizi gerçekleştirmiştir. Kontrol grubu da aynı egzersizleri EMS cihazı olmadan gerçekleştirmiştir. Çalışma öncesinde ve sonrasında vücut kitle indeksi (VKİ), denge ve sıçrama performansları ölçülmüştür. Verilerin analizi için SPSS v 26.0 yazılımı kullanılmıştır. Betimsel değerler için aritmetik ortalama ve standart sapma analizleri TV-EMS grubu ile kontrol grubuna ait ön ve son testler arasındaki iki faktörlü tekrarlanan ölçümlü ANOVA yapılmıştır. Tüm istatistiksel testler için anlamlılık kriteri p < 0.05 olarak belirlenmiştir. Araştırma bulgularına göre, grupların son test ölçümlerinin karşılaştırmasında VKİ, % yağ oranı, denge ve sıçrama değerlerinde anlamlı farklılık görülmezken, yağsız kütle değerlerinde TV-EMS grubu, kontrol grubuna göre anlamlı düzeyde artış göstermiştir. Bu bulgu sonucunda, deneysel prosedürün daha uzun süre yapılması halinde VKİ’ de değişim olabileceği, % yağ değerlerinde azalma meydana gelebileceği düşünülebilir. Ancak sedanter kadınlarda EMS ile yapılan antrenmanların fiziksel performans (sıçrama ve denge) değerlerine olumlu etkisinin olmadığı söylenebilir.

We present the discovery of TOI-3235 b, a short-period Jupiter orbiting an M dwarf with a stellar mass close to the critical mass at which stars transition from partially to fully convective. TOI-3235 b was first identified as a candidate from TESS photometry and confirmed with radial velocities from ESPRESSO and ground-based photometry from HATSouth, MEarth-South, TRAPPIST-South, LCOGT, and ExTrA. We find that the planet has a mass of 0.665 ± 0.025 M
J and a radius of 1.017 ± 0.044 R
J. It orbits close to its host star, with an orbital period of 2.5926 days but has an equilibrium temperature of ≈ 604 K, well below the expected threshold for radius inflation of hot Jupiters. The host star has a mass of 0.3939 ± 0.0030 M
☉, a radius of 0.3697 ± 0.0018 R
☉, an effective temperature of 3389 K, and a J-band magnitude of 11.706 ± 0.025. Current planet formation models do not predict the existence of gas giants such as TOI-3235 b around such low-mass stars. With a high transmission spectroscopy metric, TOI-3235 b is one of the best-suited giants orbiting M dwarfs for atmospheric characterization.

Short review of collecting technologies and methods in forest harvesting residues recovery
Authors: Ghaffariyan Mohammad Reza
Published: March 2023

Tree felling and processing can create harvesting residues including leaves and twigs (needles), cones, barks, and branches. Collecting forest harvesting residues requires application of suitable machines and working methods. This article is aimed at reviewing the published reports to identify new harvesting machines and working methods for recovering harvesting residues and the current gaps. The scope of review included published research reports/articles from 2017 to 2022 (last five years). This global review results showed that popular methods for residue collection are chipping residues at roadside/landing and integrated biomass recovery. Forwarder, cable yarder and in-field chipper are predominantly applied within various recovery methods depending on ground and stand conditions. Harvesting residues are one of the promising sources for bioenergy production which requires developing efficient and low-cost harvesting systems. Latest research findings indicate that piling harvesting residues by a harvester-pro-cessor can improve the collecting productivity by the forwarder within cut-to-length harvesting opera-tions. Integrating residue biomass recovery with conventional timber supply can reduce the total supply chain cost by 2%. Researchers also recommend applying more climate-friendly technologies and focus-ing on developing new machines with lower fuel consumption and subsequent emissions. Future studies can focus on the following subjects; a) to determine the productivity and cost rates of various residue recovery systems, b) to develop and test technologies with lower fuel consumption rates and c) to find in-novative solutions to utilize thinning materials and best practices to store and process biomass materials.
L’Union européenne à la recherche de sa sécurité énergétique
Authors: Rebière Noémie , Gobin Léa
Published: March 2023

L’Union européenne fait face à une crise énergétique de grande ampleur, amplifiée par la guerre russo-ukrainienne. Pour répondre à l’objectif politique qu’elle s’est fixé de se soustraire aux importations énergétiques russes à horizon 2027, l’UE cherche à accélérer la mise en œuvre à la fois de sa stratégie de décarbonation et de sa politique de sécurité énergétique en diversifiant ses sources, ses voies et ses moyens d’approvisionnement. Pour ce faire, elle doit construire de nouvelles infrastructures énergétiques clés, tels des terminaux gaziers, des interconnexions ou des stations de stockage. Celles-ci nécessitent des investissements conséquents et de long terme, qui sont incompatibles avec l’objectif européen d’être neutre en carbone en 2050. Les priorités géopolitiques semblent précéder les ambitions climatiques des pays européens et, malgré une baisse globale des consommations énergétiques due à l’envolée des prix, la part des énergies fossiles dans le mix européen restera à moyen terme largement prédominante.
Psychological capital and entrepreneurship: A systematic literature review of a growing research agenda
Authors: Margaça Clara , Sánchez García José Carlos , Hernández Sánchez Brizeida
Published: March 2023

Purpose: Psychological resources are determinant for the entrepreneur' individual performance. Psychological capital has been seen as one of the pillars of entrepreneurship and this is one of the reasons that the study of the relationship between these two constructs has become emerging. This systematic literature review contributes to a more robust and grounded understanding of this relationship.Design/methodology/approach: This systematic review used the PRISMA Protocol guidelines and the VOSviewer software for cluster analysis. The articles gathered in this article cover the annual period from 2006 to 2021 and allowed the identification and analysis of the main themes on psychological capital and entrepreneurship.Findings: The systematic analysis brought to light integrative relationships between the concepts of positive psychological capital and entrepreneurship, which allowed the construction of an overview of this spectrum of study. This resulted in four large groups of analysis that point the direction of the literature. The main contributions resulted in the presentation of principles and recent scientific ideas, which consider psychological capital as a valuable resource for entrepreneurship.Originality/value: This research provides an incisive understanding with the aim of being a starting point for deepening knowledge about the synergies of studies between psychological capital and the entrepreneurship research agenda. Finally, a set of future lines of study is also proposed.
Single machine Pareto scheduling with positional deadlines and agreeable release and processing times
Authors: Li Shuguang , Sun Yong , Khan Muhammad Ijaz
Published: March 2023

This paper studies the problem of scheduling $ n $ jobs on a single machine to minimize total completion time and maximum cost, simultaneously. Each job is associated with a positional deadline that indicates the largest ordinal number of this job in any feasible schedule. The jobs have agreeable release and processing times, meaning that jobs with larger release times also have larger processing times. The agreeability assumption is reasonable since both the single-criterion problems (without positional deadline constraints) of minimizing total completion time and maximum lateness on a single machine with arbitrary release and processing times are strongly NP-hard. An $ O(n^3) $-time Pareto optimal algorithm is presented. The previously known algorithms only solve two special cases of the agreeability assumption: either the case of equal release times in $ O(n^4) $ time, or the case of equal processing times (without positional deadline constraints) in $ O(n^3) $ time.
Stability of the 3D MHD equations without vertical dissipation near an equilibrium
Authors: Ji Ruihong , Jiang Liya , Luo Wen
Published: March 2023

Important progress has been made on the standard Laplacian case with mixed partial dissipation and diffusion. The stability problem of the 3D incompressible magnetohydrodynamic (MHD) equations without vertical dissipation but with the fractional velocity dissipation $ (-\Delta)^\alpha u $ and magnetic diffusion $ (-\Delta)^\beta b $ is unfortunately not often well understood for many ranges of fractional powers. This paper discovers that there are new phenomena with the case $ \alpha, \beta \leq 1 $. We establish that, if an initial datum ($ u_0, b_0 $) in the Sobolev space $ H^3(\mathbb{R}^3) $ is close enough to the equilibrium state, and we replace the terms $ (-\Delta)^\alpha u $ and $ (-\Delta)^\beta b $ by $ (-\Delta_h)^\alpha u $ and $ (-\Delta_h)^\beta b $, respectively, the resulting equations with $ \alpha, \beta \in(\frac{1}{2}, 1] $ then always lead to a steady solution, where $ \Delta_h = \partial_{x_1}^2+\partial_{x_2}^2 $.

We provide an iterative algorithm for fixed point issues in vector spaces in the paragraphs that follow. We demonstrate that, compared to the Ishikawa technique in Banach spaces, the iterative algorithm presented in this study performs better under weaker conditions. In order to achieve this, we compare the convergence behavior of iterations, and taking into account a few offered cases, we support the major findings.

A constrained optimal control framework for vehicle platoons with delayed communication
Authors: Mahbub A M Ishtiaque , Chalaki Behdad , Malikopoulos Andreas A.
Published: March 2023

Vehicle platooning using connected and automated vehicles (CAVs) has attracted considerable attention. In this paper, we address the problem of optimal coordination of CAV platoons at a highway on-ramp merging scenario. We present a single-level constrained optimal control framework that optimizes the fuel economy and travel time of the platoons while satisfying the state, control, and safety constraints. We also explore the effect of delayed communication among the CAV platoons and propose a robust coordination framework to enforce lateral and rear-end collision avoidance constraints in the presence of bounded delays. We provide a closed-form analytical solution to the optimal control problem with safety guarantees that can be implemented in real time. Finally, we validate the effectiveness of the proposed control framework using a high-fidelity commercial simulation environment.

Published: March 2023

A huge volume of Engraulis ringens (Peruvian anchoveta) is caught together with the species Pleuroncodes monodon (munida), whose potential bioactive lipids are not commercially exploited. In the present study, lipid with carotenoid pigment (astaxanthin) and essential fatty acids (EPA+DHA) were obtained from munida lipids extracted with hexane:isopropyl alcohol (He-I), acetone (Ac), ethanol (Et) and supercritical CO2 + ethanol (SC-CO2-Et). The functional quality of the fatty acids was determined by atherogenicity index (AI), thrombogenicity index (TI) and the hypocholesterolemia:hypercholesterolemia (H:H) ratio. The highest astaxanthin (ASTX) contents (4238.65 and 4086.71 µg/g lipid) corresponded to extractions using Ac and SC-CO2-Et. EPA+DHA ranged from 31.15 to 31.85% and the functional quality ranges were between 0.56-0.61 (AI), 0.19-0.21 (TI) and 1.73-1.81 (H:H). Consequently, SC-CO2-Et extraction would be advisable because of its low environmental impact. The IA and IT quality indexes suggest that the consumption of munida lipids would be healthy, although the H:H ratio shows the opposite.

Annatto seed oil (ASO) and cupuassu seed fat (CSF) were combined at the ratios: 30:70, 50:50, and 70:30 (% w/w). Their fatty acid profile, nutritional quality, FTIR (Fourier Transform Infrared) spectra, and rheological behavior were evaluated. ASO increased the content of polyunsaturated fatty acids in the blends; whereas CSF conferred higher contents of monounsaturated fatty acids. The blends exhibited low atherogenicity and thrombogenicity indices, suggesting nutritional advantages. The Newtonian fluid behavior and FTIR results suggested that mixing ASO and CSF at different proportions did not affect the functional groups. ASO showed an activation energy value which indicated that this fat viscosity was more sensitive to temperature changes. The Newtonian model proved to be suitable to describe the behavior of samples, according to statistical fit parameters R2, χ2, and RSS. The resulting blends presented improved physicochemical properties and nutritional attributes, indicating their feasibility for the development of new products.

Authors: Shmelova Tetiana , Yatsko Maxim , Sierostanov Iurii
Published: March 2023

The authors present a new approach to decision-making to ensure the proper collaboration of different personnel. Models are used in intelligent integrated decision support systems, especially for actions in emergencies. Behavioral deterministic models are used for synchronization actions of all operators, to support and timely predicting of operators' actions in an emergency. To determine the quantitative characteristics of risk levels, models for collaborative decision making (CDM) under uncertainty by the operators (pilots, air traffic controllers, flight/dispatch), and other invited specialists, have been developed. The decision-making modeling of a group of operators in case of an emergency situation such as “pilot incapacitation” was presented. The methodological basis for CDM in certainty is network planning, in conditions of Stochastic uncertainty – is a decision tree, in conditions of non-stochastic uncertainty – is a matrix of decisions, and outcomes are made this using the expert judgment method for obtaining quantity estimations.
Evaluating the Effectiveness of Boxing Headguards in Mitigating Head Impact Accelerations That Cause Concussions by Using a Dynamic Head Model
Authors: Rybak Tyson R. , Sanzo Paolo , Liu Meilan , Zerpa Carlos E.
Published: March 2023

Boxing headguards offer a form of head protection to minimize the risk of head injuries for athletes. Existing literature, however, lacks information regarding the protective capabilities of boxing headguards. This study examined the protective capacity of three boxing headguards in minimizing impact accelerations to the head that cause concussions using a dynamic head model. The researchers implemented thermoplastic polyurethane (TPU) inserts in one of the headguards and conducted static tests to examine the material properties of the headguards. The researchers also conducted dynamic testing using a surrogate headform to compare the three boxing headguards in minimizing the risk of concussion for measures of linear and rotational accelerations across different head impact locations. The results of this study revealed that TPU significantly mitigated the magnitude of linear and rotational accelerations when compared to the other headguards. This study offers an avenue to improve athlete safety.
The Usability of Management Information Systems Applications
Authors: AlFahl Husam
Published: March 2023

Many management information systems applications can be used to support businesses. One example is platforms that support electronic commerce, so retailers can sell products and services online. The use of electronic commerce applications is so common that virtually every smartphone owner has used them. In this research, the author evaluates the usability of mobile applications for electronic commerce in the Kingdom of Saudi Arabia and introduces a measure with which developers and organizations can evaluate the usability of their mobile applications. Applying quantitative research methods, including structural equation modeling, the research shows that three constructs—application design, application utility, and user interface structure—are the strongest predictors of both continued intention to use a mobile application and loyalty to the mobile application.

Background: Frequent socio-political conflicts in the past decades have adversely affected the well-being of youth in Sri Lanka. There is a need to support youth development, mitigate past trauma, and promote social harmony. School-based interventions to improve character development, emotional regulation, and tolerance have good evidence and may benefit adolescents in Sri Lanka. Our objective was to develop a novel character strength program in Sinhala to promote Leadership, Empathy, Altruism, Personal Growth, and Social Responsibility (LEAPS). This program consists of ten web-based modules and is facilitated by teachers. This initial evaluation focuses on the first module and its acceptability among students and teachers.
Method: Program modules were developed by a child and adolescent psychiatrist with the support of mental health and educational experts. The first module was piloted among grade 8 students (12-14 years) and teachers of two schools in the Gampaha District. It was designed to be interactive and contains various cultural activities and questions. On completion, participants gave feedback online via Likert scales. Ethical approval for the study was obtained from the Faculty of Medicine, University of Kelaniya.
Results: A total of 115 students and 66 teachers participated. Overall, more than 95% of students and teachers found the module appropriate and suitable. The students had more favourable ratings for the module compared to the teachers on aspects of understanding the content (p<0.001), ability to complete by self (p<0.001), suitability to age (p<0.001), shorter time for completion (p<0.001) and suitability of the design (p<0.001). Both groups suggested that the pictures and activities be increased.
Conclusions: Teaching character strengths using a web-based intervention was well accepted by adolescent students and teachers in Sri Lanka.

Health-Care Disparities in the Use of Diabetes Technologies in the UK
Authors: Barnard-Kelly Katherine , Parkin Christopher G.
Published: March 2023

Health inequalities have been a longstanding challenge for decades with widening disparities in recent years. Much focus is rightly placed on inequalities based on race/ethnicity, but it is clear that racial disparities and socioeconomic deprivation are interlinked. The connection between systematic and personal bias against individuals from the most deprived groups, irrespective of ethnicity, clearly exists. Socioeconomic deprivation appears to be an influential factor driving health disparities, with implicit bias directed against individuals living in poverty. This is reflected in access to diabetes technologies such as insulin pump therapy, continuous glucose monitoring systems, and automated insulin delivery where those from ethnic minority backgrounds and those in areas of highest deprivation are least able to access or benefit from such technological advancements. Inequalities are further reinforced by government cuts in spending. Between 2009 and 2020, net expenditure per person in local authorities in the 10% most deprived areas fell by 31% compared with a 16% decrease in the least deprived areas. These regressive cuts included a failure of health-care spending to rise in accord with historical patterns. Compounding the challenges were cuts to public health funding and reductions in welfare payments to families most in need. These widening health inequalities are unacceptable and unfair within a national health system where all individuals are entitled to the same level of care. Improved access to specialist diabetes care teams and to life-enhancing technologies could improve the health of all people with diabetes and reduce its human and financial cost.
Rook placements in $G_2$ and $F_4$ and associated coadjoint orbits
Authors: Ignatev Mikhail V. , Surkov Matvey A.
Published: March 2023

Let $\mathfrak{n}$ be a maximal nilpotent subalgebra of a simple complex Lie
algebra with root system $\Phi$. A subset $D$ of the set $\Phi^+$ of positive
roots is called a rook placement if it consists of roots with pairwise
non-positive scalar products. To each rook placement $D$ and each map $\xi$
from $D$ to the set $\mathbb{C}^{\times}$ of nonzero complex numbers one can
naturally assign the coadjoint orbit $\Omega_{D,\xi}$ in the dual space
$\mathfrak{n}^*$. By definition, $\Omega_{D,\xi}$ is the orbit of $f_{D,\xi}$,
where $f_{D,\xi}$ is the sum of root covectors $e_{\alpha}^*$ multiplied by
$\xi(\alpha)$, $\alpha\in D$. (In fact, almost all coadjoint orbits studied at
the moment have such a form for certain $D$ and $\xi$.) It follows from the
results of Andr\`e that if $\xi_1$ and $\xi_2$ are distinct maps from $D$ to
$\mathbb{C}^{\times}$ then $\Omega_{D,\xi_1}$ and $\Omega_{D,\xi_2}$ do not
coincide for classical root systems $\Phi$. We prove that this is true if
$\Phi$ is of type $G_2$, or if $\Phi$ is of type $F_4$ and $D$ is orthogonal.

O presente artigo objetiva analisar o risco e o retorno inerente a quatro índices do IMA (IRF-M, IMA-B, IMA-C e IMA-S) para auxiliar na tomada de decisão do investidor no Tesouro Direto. Para isso, calculou-se o retorno diário dos índices de fevereiro de 2006 até maio de 2017 e a partir disso analisou-se estatisticamente os resultados e as variáveis que afetaram a flutuação de preços. E em seguida, calculou-se as equações de risco como o Value at Risk (VaR), o Expected Shortfall (CVaR) e por último o Tracking Error. Como resultado, percebe-se que os títulos do IMA-C tiveram em média o maior retorno, mas foi o que pior replicou o benchmark. O IMA-B, por sua vez, foi o índice de maior risco ao contrário do IMA-S que obteve o menor risco e retorno. Por último, o IRF-M replicou muito bem a média dos benchmarks dos demais índices.

The non-resonant microwave discharge in strong magnetic fields was investigated in Heliotron J under the condition, ωce/ωMW > 1 (ωce and ωMW are the angular electron cyclotron frequency and the angular microwave frequency, respectively). Following the production of a non-resonant microwave discharge plasma, it undergoes
several phases in sequence: breakdown and formation of pre-ionized plasma, increase in linear and nonlinear phases of plasma density, and quasi-stationary stage. Several modes of non-resonant microwave discharge were investigated. In the power-scanning mode in non-resonant microwave discharge, a higher plasma density than that in
the constant-power mode is achieved. The maximum average density achieved in the experiments is substantially greater than the critical density for O-wave (ordinary waves) 7.45 ⸱1016 m -3 and can reach the value of 2.5⸱10 18 m -3.

DYNAMICS OF THE ION ENERGY DISTRIBUTION AND PLASMA PARAMETERS IN FLOWS OF THE NON-SELF-SUSTAINED ARC DISCHARGE IN MOLYBDENUM VAPORS
Authors: Borisenko A.G.
Published: March 2023

In these experiments, the energy distribution functions of ions and plasma parameters in the generated flows of a non-self-sustained arc discharge in pure molybdenum vapors and in a mixture of molybdenum vapors with gas were investigated. It is proved that there are practically no ions with energy over 100 eV in the flows, and that the maximum of the ion distribution function shifts to lower values of the ion energy when the vacuum arc discharge current increases. The values of the plasma potential in the flows, the density and temperature of the plasma electrons at different discharge currents were determined. It is shown that the working medium of the discharge in pure molybdenum vapors is formed during the diffuse evaporation of the working material, which ensures the absence of droplets of the working material in the generated flows. Growth rates of deposited molybdenum films at different operating modes of the discharge were determined. It has been proven that the plasma flow created by a discharge of this type in molybdenum vapors has a compensated volume charge and can be used to apply metal films and coatings to substrates made of various materials, including dielectric ones.

A pilot model of an ozone generator with a pulsed power supply has been developed. The ozone generator can be used for disinfection of domestic and industrial premises, in medicine and the chemical industry. Ozone is generated by a surface dielectric barrier discharge reactor (SDBD), consisting of 18 parallel-connected quartz tubes, inside and
outside of which spiral the stainless steel high-voltage electrodes are wound. The measurements of the main parameters of the ozone generator showed that the ozone concentration reached 57 mg/l, and the output ozone concentration is 9.4 g/h. The developed design takes into account the technical features of the implementation of a
particular type of discharge used, allows reducing energy consumption for ozone generation, having improved output parameters.

A pequena cidade: inserção regional, dinâmica e produção do espaço urbano de Piraúba-MG
Authors:   , Vidal Angélica Silva Arruda
Published: March 2023

A maioria das cidades brasileiras podem ser consideradas pequenas, seja pelo seu porte demográfico, pela dimensão, pela inserção na rede urbana ou na participação na economia regional. Apesar de maioria no território, as pesquisas realizadas sobre o espaço urbano brasileiro são focadas em cidades grandes, mais recentemente passou a incluir as médias, deixando lacunas a serem preenchidas no que tange ao estudo das urbes que compõe as pequenas cidades. Durante a elaboração do projeto de pesquisa foi identificada uma carência de pesquisas voltadas para compreender a dinâmica de produção e reprodução do espaço urbano das pequenas cidades, bem como quem são os agentes atuantes, quais processos se realizam em seu território e quais formas urbanas são consequentes dessa dinâmica. Em busca de trabalhos dentro da temática foi identificado que não haviam pesquisas que tratassem do espaço urbano da pequena cidade como um todo, nem que elencassem os agentes atuantes. Portanto essa pesquisa busca responder a seguinte pergunta: Como e quem produz o espaço urbano da cidade de Piraúba e quais são as consequências físico-territoriais dessa dinâmica? Como campo de estudos foi escolhida a cidade de Piraúba, localizada na Região Imediata de Ubá, na Zona da Mata de Minas Gerais. A escolha se justifica pela relação da pesquisadora com o campo de estudos e decorrente percepção do desenvolvimento da urbanização do município, ocorrida a partir dos anos 1990, a área urbana tem passado por expansão tanto vertical como horizontal e pelo desenvolvimento de setores econômicos propriamente urbanos. A dissertação se dividiu em quatro capítulos, dois de embasamento teórico, sobre espaço urbano e pequena cidade, dois de pesquisa, sobre a inserção regional de Piraúba e a produção do espaço urbano do município. Ao fim debate-se a presença dos agentes e a forma com que os processos acontecem na cidade. Palavras-chave: Pequena cidade. Produção do espaço urbano. Inserção regional.

Published: March 2023

Este estudo objetivou avaliar o acesso de pacientes com necessidades especiais aos serviços odontológicos no município de Viçosa e Microrregião. Para investigar estes desfechos, nesta dissertação é apresentado um artigo original intitulado “ACESSO À ASSISTÊNCIA ODONTOLÓGICA DE PACIENTES NECESSIDADES ESPECIAIS NO SISTEMA ÚNICO DE SAÚDE”. COM Trata-se de estudo transversal descritivo cuja população foi constituída por dentistas da Atenção Primária de Saúde, e pacientes Oncológicos e Nefrológicos de uma cidade da Zona da Mata Mineira e de sua Microrregião. Os dados foram coletados mediante a aplicação de questionários validados e analisados por meio de estatística simples. Com respeito aos aspectos éticos. Dos 31 dentistas entrevistados, 22 afirmaram atender o paciente com necessidade especial, 26 realizaram exame clínico e o tratamento possível, 9 não se consideraram aptos para o atendimento e encaminharam o paciente a um colega e 27 profissionais responderam já encaminharam paciente para a Atenção Secundária. Dos 292 PNEs avaliados, 167 eram oncológicos, em que 83 relataram ter facilidade em conseguir o tratamento, e 125 PNEs eram nefrológicos, em que 50 afirmaram ter facilidade de acesso ao tratamento odontológico. Destaca-se, que os pacientes encaminhados para a Atenção Secundária foram predominantemente para realizarem ações de promoção da saúde, prevenção de agravos, procedimentos cirúrgicos e de endodontia. Embora, o tratamento Odontológico ao PNE, seja realizado pela maioria dos dentistas deste estudo, evidencia-se que os atendimentos na Atenção Secundária, são de demandas que seriam passíveis de resolutividade na Atenção Primária à Saúde (APS) por contemplarem seu escopo de complexidade clínica.
