BACKGROUND

Third-wave psychological treatments, such as Acceptance and Commitment Therapy (ACT), can be effective for improving depression and anxiety in youth. However, third-wave therapeutic techniques such as cognitive defusion can be abstract, challenging to learn, and difficult to apply in real-world settings. Translating these techniques into virtual reality (VR) may provide interactive, enjoyable, and concrete learning opportunities, potentially enhancing engagement and effectiveness. This study evaluated a novel VR application (‘app’) that translates the technique of cognitive defusion into a brief, gamified VR experience.

OBJECTIVE

The objectives of this study were to evaluate the feasibility, acceptability, usability, and safety of the VR cognitive defusion app, examine whether it could improve negative thinking and mood states, and understand how it compared to a non-VR cognitive defusion exercise.

METHODS

In a mixed methods experimental study, 20 young people completed both a VR and audio cognitive defusion exercise in randomized order within a single session. Quantitative state-based measures were taken before and after each exercise, and a qualitative interview at the end focused on how the two experiences compared.

RESULTS

It was feasible to recruit participants, and all participants completed both exercises and assessments. Both the VR and audio exercise were acceptable to participants, with qualitative themes highlighting a preference for VR due to the novel and engaging format, however there was a need for better guidance and more personalized environments. No severe adverse events were reported, though one participant experienced distress during the VR exercise. Pre-post effects showed improvements in thought discomfort, cognitive defusion, and state anger for both the VR and audio conditions, with the latter showing broader improvements, including thought negativity, rumination, tension, depression, anger, and confusion.

CONCLUSIONS

The VR cognitive defusion app was feasible, safe and acceptable for young people, with potential to enhance mental health treatment through an engaging and enjoyable approach to learning third-wave CBT techniques. While VR was preferred by participants, further refinements could improve effectiveness. Future research should focus on enhancing the VR app design based on user feedback, incorporating audio guidance, and conducting a larger trial in real-world settings to thoroughly evaluate its effectiveness and implementation.

Published: December 2024

Wellness is the theoretical underpinning of the counseling profession (Witmer, 1985) and the wellness of graduate counseling students has been thoroughly studied (Puig et al., 2012; Young & Lambie, 2007). There is a gap in research related to the wellness of accounting students, a group not typically focused on wellness. This investigation examined overall wellness and perceived stress in 108 undergraduate accounting majors at two large Midwestern universities. Results indicated moderate levels of perceived stress and overall wellness, with the physical and social domains of wellness being rated the lowest. Recommendations for mental health counselors and student affairs professionals working with accounting students are discussed.
K-5 School Counselors’ Use and Perception of Educational Apps for Students with Disabilities
Authors: Bullen-Johnston Casie , Lee Sung Hee
Published: December 2024

School counselors play an important role in supporting students with disabilities. While counseling is done primarily through verbal communication, students with disabilities may have difficulties in communication, which could hinder their participation in such counseling sessions. One way to remove their communication barriers is to use educational technology, such as applications (apps) on mobile devices. Yet, current research is still uncertain regarding how school counselors, specifically K-5, perceive and incorporate these apps into their counseling sessions. The present study surveyed and reported the use and perception of school counselors working with K-5 students with disabilities in the state of Ohio. The survey data showed that the majority of K-5 school counselors did not use educational technology including apps; however, a significant number of counselors perceived technology apps as being important for students with disabilities and would utilize the technology if their school provided access to it.

Creating a conceptual framework for analysis of vascular plant diversity in a coastal landscape: functional aspects and ecosystem services for plants at the Baltic Sea
Authors: Ievinsh Gederts
Published: December 2024

The aim of the study is to develop a conceptual framework for the analysis of the diversity of coastal plant species of the Baltic Sea in relation to adaptation to specific conditions and participation in the provision of ecosystem services. The possibilities of coastal plant classification for further analysis of their properties will be described, concentrating on both opportunities and weaknesses of each particular system. These will include approaches related to aspects of taxonomy, life forms and functional strategies, geographical- and habitat-related distribution, ecological indicators, species associations forming vegetation, dependence on landforms as well as provision of ecosystem services. All of these approaches make important contributions to the context of coastal plant occurrence. However, at the level of distribution of individuals of plant species, the perspective is in analysis of their relationship with coastal landscape elements, landforms. Abiotic and biotic aspects of the ecological niche should also be taken into account for the analysis of plant functional diversity, together with the morphological, physiological and biochemical characteristics of individuals. The importance of plants in the functional diversity of coastal ecosystems should be linked to their contribution to ecosystem services.

Published: December 2024

Introducción: la diabetes, como patología crónica mundial, ha exigido un abordaje multidisciplinar, dado que se relaciona con múltiples patologías, entre ellas, el deterioro cognitivo, el cual es más evidente en personas de mayor edad. El objetivo de esta investigación fue realizar un estudio prospectivo para determinar la prevalencia entre diabetes mellitus y el déficit cognitivo, en una corte de pacientes en una institución del nororiente colombiano, mediante el test de evaluación cognitiva de Montreal (MoCA, según sus siglas en inglés).
Materiales y métodos: participaron 170 personas que cumplieron con los criterios de inclusión, aplicándoles el test de MoCA, versión 8.1 en español, y se solicitaron paraclínicos completos. Para elaborar y compartir el cuestionario con los participantes se usó Google Forms. Luego, para la validación de los resultados del análisis estadístico, las variables categóricas se describieron con frecuencias absolutas y porcentajes, mientras que las variables continuas se validaron con medidas de tendencia central y dispersión, y la distribución se evaluó mediante la prueba de Shapiro-Wilk. Así mismo, para el análisis bivariado en variables continuas se usó el test de chi cuadrado y el exacto de Fisher, y para las continuas se usó la prueba U de Mann-Whitney. Finalmente, para realizar los análisis estadísticos se usó el programa Stata 16.
Resultados: en el test de MoCA se evidenciaron diferencias estadísticamente significativas con la edad, siendo mayor el grado de deterioro cognitivo severo en mayores de 50 años.
Discusión: la diabetes como patología metabólica crónica multifactorial, se asocia a deterioro cognitivo, con una asociación estadísticamente significativa en personas mayores de 50 años con larga historia de DM2. El tamizaje temprano y el buen control metabólico son importantes para minimizar el impacto cognitivo y de salud en general de esta población.
Conclusiones: el control glucémico adecuado, el mantener una mente activa y el control periódico, especialmente en personas mayores de 50 años o en pacientes con larga data, son aspectos a tener en cuenta para evitar la aparición o la rápida progresión de los trastornos cognitivos en la población con diabetes.

Published: December 2024

This article aims to analyze the definite changes by the Brazilian National Strategic Defence (NDS) about the Brazilian Airspace Control System (SISCEAB). The NDS indicates the Brazilian Airspace Defence Command (COMDABRA) as the new manager of the equipments and resources of surveillance and communication for the airspace control. It was made a research on books and documents approaching the facts with theories such as, the General Systems Theory and those which deals with concepts about Security and Defence, because the Air Force manages the Airspace Defence and the Civilian Air Traffic Control. The analysis of the NDS suggests a modification in the structure of COMAER, including the shift from the Air Traffic Control to civilian management. This fact is possible to come up because one of the NDS’ goals is to restructure the Armed Forces, besides the Air Force has agreed with this possibility in 2007.

This study refers to the controversy that began in 2000 the transfer of the Escola Superior de Guerra (ESG) from Rio de Janeiro to Brasilia, precisely about what determines the National Defense Strategy: the transfer of the ESG to Brasilia. This essay, which was initially a result of bibliographical readings and documental research, as well as exploratory research, aimed at developing studies on whether the transfer of the ESG from Rio de Janeiro to Brasilia was necessary. First, the study shows the foundation, the performance and the current direction of the ESG, as well as discusses the counterpoints of the change of location. Secondly, it addresses the creation of the National Defense Institute (INAD), based in Brasília, and reaffirms the necessity of the Escola Superior de Guerra, but with a new approach - focused on the interoperability, joint staff forces, and on an interinstitutional integration of a mandatory nature for the senior officers of the national Armed Forces. Lastly, final comments are made portraying that the feeling should be left behind and an action must be taken, because, in a changing world, excellent opportunities arise for creation, recreation, unity and innovation. This whole new world demands post-modern thoughts and actions. Thus, it directs the ESG to the continuing and integrated education for the Officers of the FFAA and INAD for the initial and ongoing training of the Defense Analysts, as well as to the creation of Course of Defense, Development and Diplomacy for the Officers already selected for the generalship

Authors: Rastelli Fábio Luiz Barbosa
Published: December 2024

The automation technology found in Aviation a fertile field for its development. This development reached the Brazilian Air Force C-130 aircraft through the modernization program of the ten aircraft acquired from the Italian Air Force, with its beginning in 2005. The objective of this study was to determine whether the modernization of the C-130 meets the ergonomic principles for a perfect human-computer interaction, aiming mainly at the safe operation of aircraft, and considering the piloting or the pilot as the main factor in the cause of accidents. In order to achieve this goal, we adopted a descriptive methodology, through desk research and literature. Through a thorough theoretical study on the subject, it was possible to evaluate the ergonomic influence based on two aspects: the suitability of the position of EFIS control panel for the pilot, under instrument flight, and adequacy of the position of the backup instruments. To do that, the equipment incorporated in the aircraft for modernization were described, detailing their role and location in the cabin. Data on ergonomic factors related to automation and the flight were also collected, in order to seek a well-designed cockpit and the problems that may occur if that is not observed. In these two devices, probable loss of situational awareness and the appearance of visual illusions or spatial disorientation in the pilot were identified. These points were listed and discussed as a contribution to the operators of the aircraft and the other Brazilian Air Force squadron passing through the same process.

Informal reports based on personal pilots experiences, at 7th Squadron of the 8th Aviation Group (7°/8° GAv), hypothesizing that after the introduction of H-60L Blackhawk helicopter, a greater incidence of stress factors in operational situations, has arisen in spite of the high technology and safety of the new equipment This fact caused uneasiness and it was verified the relation between the 7°/8° GAv operational characteristics after the introduction of H-60L Blackhawk and the stress level perceived by the pilots while in mission, therefore a scientific research was raised. This research was divided in two phases: the first one, with the purpose of surveying what were the operational changes introduced by the new helicopter while the second phase a questionnaire was applied. For that purpose, it was collected the profile of missions lead by the 7°/8° GAv before and after the implantation of the H-60L Blackhawk. It has surveyed the pilots stress perception in missions that used to be accomplished before the new ones. Hans Selye’s General Adaptation Syndrome Theory (1956) and Albrecht’s Situational Stress Theory (1979) were the base for this work. Finally, after analyzing the data it was concluded that there were influences on the pilots stress level by the operational characteristics of the 7°/8° GAv, acquired after the introduction of H-60L Blackhawk.

Published: December 2024

The objective of this research was to investigate the prevalence of motion sickness among aviation students of the Brazilian Air Force in Pirassununga, state of São Paulo, their search for medical treatment and the influence of symptoms on their performance. To this end, a cross-sectional prevalence study was conducted, based on a questionnaire created by the researcher.  Then, the data were tabulated and analyzed confidentially. The number of cadets evaluated was 105. Their average age was 20 years, and the majority were male (97%). The small number of women does not allow inferring a comparison between the sexes. The number of individuals diagnosed with motion sickness was 46 (43.8%), while in international studies it ranges from 10% to 39%. Stunts were the most provocative maneuvers, cited by 28 of the 46 cadets. Of the 46 cadets affected, 45.6 (n=21) denied interference of symptoms in performance, 26.1% (n=12) reported that their performance was affected in one mission, 13% (n=6) in two missions, 4.4% (n=2) in three missions, 8.7% (n=4) in four or more missions and 2.2% (n=1) in all missions, corroborating previous studies of decreased performance caused by motion sickness. Of the cadets with symptoms of motion sickness, 58.7% (n=27) sought medical assistance after the crisis, but only 30.4% (n=14) underwent some type of treatment. Thus, a prevalence of motion sickness among Brazilian cadets was slightly higher than that found in international studies.

Published: December 2024

This paper to intended to present how a set of logistic information, made available by the Materials and Services Integrated Logistics System (SILOMS), complies with MSG-3 (Maintenance Steering Group-3) methodology, applied to Brazilian Air Force (FAB) C-105 Amazonas airship maintenance plan. The research, based on technical documents on MSG-3 and COMAER handbooks and instructions, has identified the information required to an eventual review of the maintenance plan. A comparison between the needs and the content made available by SILOMS has shown a partial compliance that hinders the plain use of MSG-3 methodology. In this paper it is concluded that this lack of information available makes unfeasible any initiative related to C-105 Amazonas airship maintenance plan review, if the correct support of MSG-3 methodology is a requirement.
O papel das Nações Unidas para a manutenção da paz e segurança internacionais
Authors: Philippini Ana Claudia Moreira Miguel
Published: December 2024

The United Nations was created with the purpose of maintaining peace and international security to replace the extinct League of Nations. Within its organizational structure, the Security Council was responsible for the direction and improvement of the system of collective security. During the Cold War the role of the Security Council was compromised due to the veto policy used by the United States and the Soviet Union in the dispute for primacy in the international system. Peacekeeping operations have emerged in this context, as mechanisms to promote international peace and security in the face of Council stoppage. This article aims to analyze the use of the UN in international politics, whether in regard to the institutionalization of norms both in regard to international security. To do so it was based on a literature of authors such as Claude, Mingst, Karn, Bellamy, William, Buzan, Barnett, Finnemore, Thakur, Schnabel, among others. In order to complement the study, research was performed using the UN Charter and reports “An Agenda for Peace” and “Bahimi”. The main conclusion is that, with the end of bipolarity, the role of the UN has become more effective due to reduced veto policy, which allowed the decision-making process of the Security Council was stimulated and complex peace operations including humanitarian crises in intra -state conflicts have arisen.

This article aims to analyze the use of unmanned aerial vehicles (UAVs) in the context of irregular warfare. Through a guided theoretical foundation in the latest concepts and definitions about the asymmetric conflicts, the practical experiences of the use of drones and the data and information related to the results obtained during and after conflict, we seek to understand the dynamics of applicability of the equipment in question, taking into account especially its psychological impact in the many spheres of the societies involved, making a specific evaluation of the conflict in Afghanistan. This text does not aim finding exact answers, but lighten the scenario involving these two issues, which although much debated, have few national studies and profound difficulties of conceptualization and regulations due to the contemporaneity of them.
Debates sobre o ensino nas academias militares e sua articulação no campo científico brasileiro
Authors: Montejano Paulina
Published: December 2024

Focusing on our object of study, which is the officers’ training at the Brazilian Air Force (FAB), we have initially resorted to several sources of data to gather researches addressing military education in Brazil. In this process, the small number of productions found in the educational field has motivated the researcher to an exercise of reflecting on the perceived gap in the literature and its articulation with the considerations of Pierre Bourdieu’s theory on the scientific field. Thus, the purpose of this study is, in summary, to present the way in which military affairs are being established in the field of research on education, elucidating historical aspects of this movement. To reach the objective proposed, in the methodology adopted, bibliographical and Internet researches were used, specifically in books, articles, dissertations and theses by authors who approach the process of social practice development in the military field in Brazil, which allowed us to describe, analyze and discuss how the research in the military field has been carried out in our country. The obtained result has shown that the experience of dictatorship and the absence of external threats in our territory have left the topic out of discussions for a long period. However, in circumstances of current challenges in the 21st century and the end of the dictatorship, military studies in Brazil have been gradually resumed
Maquiavel, o estrategista pensador e sua contemporaneidade

Published: December 2024

Niccolò Machiavelli became one of the most celebrated and studied Renaissance thinkers that made the advent of the modern Era possible. However, even if his most famous work is the book The Prince, other works also bring strong relevance over his TrailBlazer bias. The present paper is intended to demonstrate that his contribution goes beyond the political thresholds, also bringing innovations in the strategic area and the use of force by the instituted power. This study is based on all of the most well-known works of the Florentine (The Prince, Discourses on the first decade of Tito Lívio and The art of war), combining and confronting this bias to subsidize the highlighting of which areas of strategic thinking he addressed. It is therefore intended to present its contribution in the formulation of rules that, only long after, founded new advances of the western strategic thought. On the other hand, it is also intended to show, by means of a critical approach, the paths indicated by it that have turned out to be unpromising to this day.

Published: December 2024

One of the great challenges faced by aviators is to realize the individual physiological effects caused by hypoxia. Hypoxia is the condition that the human body faces when it does not receive an adequate supplement of oxygen in the body tissues and cells. Deprivation of appropriate oxygenation leads to reduced cognitive and visual capacity, thereby leading to unconsciousness and even death in extreme cases. It is therefore required that aviators receive training to recognize such symptoms to ensure flight safety. This paper describes the development of a portable and low cost Normobaric Hypoxia Chamber (NHC). The NHC provides training in situations of hypoxia for aviators. To be portable and cost-effective, the NHC was constructed using a PVC pipe structure, coated with transparent vinyl canvas and fitted with latches to access and seal the internal atmosphere of the chamber from the rest of the environment. The NHC control system was designed to acquire signals from O2 and CO2 sensors, to process and control the hardware of the gas mixture actuators, which allow the oxygen concentration within the NHC to be changed, and to homogenize the air within the NHC and carry out the exhaustion of the interior of the chamber. The results show that the development of the CHN has fulfilled the prerequisites established in the project. The NHC can be used to train aviators under controlled conditions and to carry out research on human physiology related to hypoxia.

The objective of this research is to verify to what extent the curricular content of the Operational Specialization Course in Rotary Wing Aviation (CEOAR), taught by the First Squadron of the Eleventh Aviation Group (1st/11th GAV), responsible for helicopter pilot training of the Brazilian Air Force (FAB), develops the necessary skills for the pilot who will perform the Attack Action with the AH-2 Sabre. From a theoretical framework, methods that enabled the collection of the desired data have been applied. Thus, the necessary competences for the pilot who will perform the Attack Action with AH-2 have been determined by a survey with the application of the Delphi Method (expert opinion) in two rounds that resulted in 15 knowledge, 17 skills and 20 attitudes. The competences developed in the CEOAR, in turn, were extracted by documentary research of the Minimum Curriculum and its Order of Instruction. The correlation of these lists revealed that the current curriculum of the CEOAR is efficient for the proposal to develop, although superficially in some cases, 100% of the knowledge, 82% of the skills and 95% of the desired attitudes, as presented in the analysis of the data.

In high, mixed, middle-aged and maturing Penduculate oak stands, the
possibility of using aerial photogrammetry in the inventory was tested,
both to obtain informa?tion related to site and stand information and to
determine numerical elements (number of trees, basal area and volume per
hectare) obtained on the basis of data read from the images (crown diameter,
height and estimated breast height diameter of the tree based on the
selected mathematical model). Most of the information from the site and
stand infor?mation, especially the information about the above-ground parts
of the forest (presence of dead cover, ground vegetation, shrubs, weeds,
saplings and the degree of their damage, etc.) could not be identified from
the image. There was a significant difference in the aver?age number of
trees, basal area of stands and stand volume per hectare determined on the
basis of aerial image data, compared to the values determined by the
terrestrial survey. In middle-aged stands, the number of trees determined
from aerial image is 21.5 % higher and in maturing stands 9.5 % lower than
the values determined by a total measurement. In middle-aged stands, the
basal area AP-1 is 13.5 % higher and AP-2 15.6 % higher than the values
determined in the total measurement. In the maturing stands, these
deviations are 13.1 % and 3.7 %. The stand volume is the element with the
greatest deviations compared to the total measurement. In middle-aged stands
the difference is 31 % and 28.1 %, and in maturing stands 37.9 % in AP-1 and
even 67.1 % in AP-2. The reasons for the impossibility of a precise
interpretation of most of the information related to the information of the
site and the stand and for the significant differences in the numerical
elements compared to the total measurement lie in the broad and intertwined
crowns (dense canopy closure) of the oaks in the upper storey and in the
vertical structure of these mixed stands. The results obtained exclude the
use of aerial photogrammetry in the inventory of this certain forests, as it
does not provide a reliable information basis for the development of
realistic forest management plans. Possible applications exist in
distinguishing of land use, locating fire areas, areas af?fected by
hurricanes and other disasters, etc., and even in the inventory of pure
stands with low canopy closure.

Until now, protective forest belts have mainly been raised around the world
with the aim of protecting against aeolian erosion. Nevertheless, they
represent multifunctional objects, which, in addition to the primary
function of protection against erosion, perform a large number of ecosystem
services and represent one of the most frequently applied practices of
agroforestry. Protective forest belts are a suitable measure for increasing
forest cover, improving soil quality, as well as for the restoration of the
agricultural production area in general, thus changing the entire landscape.
This paper shows the impact of protective forest belts on carbon storage in
the soil. The tree and shrub species in these belts are of particular
importance to the state of organic matter in the soil in the belts. The
inclusion of these agroforestry measures in the system would significantly
contribute to the regeneration of the land area.
Inonotus hispidus (Bull.) P. Karst. - bioecological characteristics, significance and possibility of use for medical purposes (medicinal properties)
Authors: Radulovic Zlatan , Karadzic Dragan , Milenkovic Ivan
Published: December 2024

Inonotus hispidus develops as a parasite on living trees and causes white,
central rot. Infections occur through injuries on branches or stems. Its
ability to cause cankers differentiates it from fungi that only cause heart
rot. In Serbia, it is quite frequent on Persian walnut (Juglans regia),
black walnut (Juglans nigra), plane tree (Platanus acerifolia) or common ash
(Fraxinus excelsior). In urban conditions, apart from plane trees,
carpophores sometimes occur on horse chestnut (Aesculus hippocastanum),
sycamore maple (Acer pseudoplatanus), Turkey oak (Quercus cerris) and some
fruit trees (e.g. Malus spp.). The colony of this fungus in media amended
with gallic and tannic acid shows a positive oxidase reaction (the diffusion
zone is dark brown, opaque, spread over a considerable distance from the
colony?s periphery, with equal intensity on media with gallic and tannic
acid). After seven days of incubation, the growth of the colony on the

transformações do Estado no desenvolvimento capitalista contemporâneo: do capitalismo regulado ao capitalismo neoliberal
Authors: Franca Acson Gusmão
Published: December 2024

Esse artigo discute as transformações que ocorreram no papel do Estado em relação ao desenvovlimento capitalista em dois importantes momentos históricos distintos: os anos dourados (1945 - 1970) e o período pós-1970. Desse modo, procura-se compreender como o mesmo alterou a sua forma e reorientou as suas funções, com o principal intuito de garantir ao capital as condições para a sua valorização; primeiro, na esfera produtiva, e, em seguida, na esfera financeira. Em suma, esse esforço de síntese nos permitirá construir uma revisão crítica acerca do Estado, tanto na sua formatação Keynesiana quanto na Neoliberal, revelando os reais interesses que estão por trás da sua intervenção e as consequências disso para as esferas do capital e do trabalho.
Cuidado e renda das pessoas idosas no Brasil: uma equação para além da educação financeira?
Authors: Debert Guita Grin , Félix Jorge
Published: December 2024

O artigo desce da análise macro e investiga o aspecto micro para captar o perfil sociológico da pessoa endividada. Segue a trilha de gastos de cuidado de longa duração para o risco de inadimplência. O rastreamento pretende ampliar a discussão na definição da “financeirização da velhice” (Debert e Félix, 2024), isto é, a invocação entre Estado e mercado para assumir serviços de proteção social antes típicos da esfera pública, configurando assim o que foi denominado de “Estado fiador” (Debert e Félix, 2024). São analisadas três pesquisas relevantes para guiar a política econômica brasileira. É destacada a importância de políticas de proteção social para mitigar o peso dos custos de cuidado na cesta de consumo das pessoas idosas e problematizada a solução apontada por governo e organismos multilaterais de promover educação financeira para combater o endividamento vis à vis a queda da renda.
“Igrejas S/A”: o evangelicalismo não denominacional brasileiro como uma empresa religiosa neoliberal
Authors: Viração Francisca Jaquelini de Souza
Published: December 2024

O presente trabalho procura defender a ideia de que as igrejas evangélicas não-denominacionais brasileiras se comportam como empresas neoliberais. No texto, o neoliberalismo é entendido a partir das reflexões de Dardot e Laval, como uma racionalidade que toma conta de todas as esferas da vida, portanto, também da esfera religiosa. A discussão é feita a partir de como o Estado foi transformado em um Estado empresarial, através de uma mudança conceitual das funções do Estado. E assim como o Estado foi transformado em um Estado empresarial, através de mudanças conceituais especialmente na linguagem, comparar-se-á o mesmo fenômeno nas igrejas, analisando as transformações na linguagem, estética e especialmente na arquitetura. Por fim, pretende discutir o que são igrejas evangélicas não-denominacionais, suas origens, como pensam e atuam, e por que consideram o capitalismo como a ordem natural da vida.

Many factors can influence the extubation of premature infants and it is not safe to use only the spontaneous breathing trial. Objective: To connect cardiac, neurological and pulmonary factors that influence the extubation success in premature infants submitted to the 5-minute Spontaneous Breathing Trial (SBT). Methods: The sample consisted of 27 premature infants that passed through the weaning protocol until eligibility for extubation. The premature infants were followed daily from birth to post-extubation. The extubation protocol/checklist was composed for clinical and neurological conditions, pulmonary and cardiac factors, medication, post-extubation ventilatory support, physiological variables, ventilatory parameters and SBT test with the Silverman Andersen Respiratory Severity Score (SA-RSS). Descriptive analyzes of quantitative variables and Mann-Whitney statistical tests were performed. Results: The ventilatory parameters that showed statistical differences between the groups were plateau pressure and tidal volume. The gestational age (GA) using Capurro method, GA corrected and birth weight were higher in the success group (0.02, 0.003 and 0.0). The use of caffeine may have contributed to successful extubation (p = 0.03). The post-extubation support that presents statistical significance was non-invasive intermittent positive pressure ventilation (NIPPV) (0.01). Conclusion: The study pointed out important variables that contributed to the extubation success, such as the ventilatory parameters, clinical stability and use of caffeine for the weaning process.

Published: December 2024

Objetivo: avaliar a intensidade dos fatores de estresse entre estudantes do curso de enfermagem durante sua vida acadêmica. Métodos: realizou-se um estudo quantitativo, descritivo e exploratório, no período de junho a agosto de 2023, junto aos estudantes de enfermagem de uma instituição de ensino superior privada e filantrópica no interior do estado de São Paulo. Utilizou-se o instrumento Avaliação do Estresse do Estudante de Enfermagem, composto por dados sociodemográficos e aspectos específicos em situações comuns na rotina dos estudantes para quantificar a intensidade do estresse, abrangendo seis domínios: “Ambiente”, “Atividade Teórica”, “Atividade Prática”, “Comunicação”, “Gerenciamento de Tempo” e “Formação Profissional”. A análise dos dados incluiu estatísticas descritiva e inferencial para identificar associações entre variáveis. Resultados: dos 66 participantes, 43,9% estão na faixa etária entre 21 e 25 anos; 77,2% são do gênero feminino; 28,7% encontram-se matriculados no 2º período do curso, sendo que 59% dos entrevistados já trabalham; 68,1% residem com a família; e 66,6% moram na cidade do curso. Os resultados do nível de estresse foram estratificados pela classificação geral. A frequência de classificação da intensidade do estresse indicou baixo nível em todos os seis domínios. Houve associação significativa nos domínios do “Ambiente” com duas variáveis: idade (p - valor: 0,023) e reside em Sorocaba (p - valor: < 0,001); também entre “Atividade Teórica com local de moradia” (p - valor: 0,004). Conclusão: a análise ao longo dos períodos revelou um resultado favorável, pois os estudantes de enfermagem conseguem manter uma rotina acadêmica com baixo nível de estresse, evidenciando...

Ética na arbitragem e seus desafios assim como reflexões sobre sua natureza híbrida
Authors: Pretti Gleibe
Published: December 2024

A Lei de Arbitragem (Lei nº 9.307/96) trouxe para o ordenamento jurídico brasileiro a regulamentação da arbitragem como método de resolução de conflitos, alternativo ao Poder Judiciário. Contudo, a natureza jurídica da arbitragem ainda é alvo de debates e divergências doutrinárias e jurisprudenciais. Embora a Lei 9.307/96 não defina expressamente a natureza jurídica da arbitragem, ela apresenta características que permitem classificá-la como um instituto híbrido, com elementos de jurisdição e de contrato. Por um lado, a arbitragem se assemelha à jurisdição estatal, pois produz decisões com força de sentença judicial, vinculando as partes e seus sucessores. Além disso, a sentença arbitral pode ser executada diretamente, sem necessidade de homologação judicial. Por outro lado, a arbitragem possui uma forte natureza contratual, pois se origina da vontade das partes, expressa em um contrato (cláusula compromissória ou compromisso arbitral). As partes têm ampla liberdade para escolher os árbitros, o procedimento e o direito aplicável ao caso. Diante dessas características, a arbitragem pode ser compreendida como uma forma de jurisdição privada, exercida por árbitros escolhidos pelas partes, com base em um contrato. Essa natureza híbrida da arbitragem é o que lhe confere flexibilidade, eficiência e autonomia, tornando-a uma alternativa atraente para a resolução de conflitos. Para conduzir esta pesquisa, foi utilizado o método hipotético-dedutivo, empregando uma abordagem comparativa e a técnica de documentação indireta. Realizou-se uma revisão bibliográfica em livros e periódicos jurídicos, além de consultas a documentos e sites relevantes.
