Authors: Santang Nur Amalia , Sutanto Yusup Subagio , Septiawan Debree
Published: October 2023

ackground: Bronchoscopy is a relatively safe diagnostic and therapeutic procedure, but it is often reported as an uncomfortable experience and causes acute procedural anxiety that affects the procedure and the patient and operator's comfort. Anti-anxiety drugs have the risk of causing mild to severe side effects. Therefore, we need premedication with potent anxiolytics with minimal side effects, such as the use of aromatherapy. This study aims to analyze the effectiveness of aromatherapy as an additional premedication to reduce anxiety, respiratory rate, pulse rate, and pain in patients undergoing bronchoscopy.
Method: A clinical study with experimental quasi pre-post test control group design using consecutive sampling was performed in pulmonary patients undergoing bronchoscopy in dr. Moewardi Hospital from February to March 2020. The study subjects were randomized into three groups: lavender aromatherapy, orange aromatherapy, and control. Hospital anxiety and depression scale (HADS) score, respiratory rate, pulse, and visual analogue scale (VAS) pain score were measured before and after bronchoscopy. 
Results: A total of 45 subjects of lung patients undergoing bronchoscopy participated in this study. Post hoc test differences in the HADS anxiety score of lavender and orange groups showed a significant decrease (P=0.011); (P=0.083), respectively. The decrease in the control group was not significant (P=0.622). There was a significant decrease in the respiratory rate of lavender (P≤0.0001), and orange groups (P=0.001), while the control group did not decrease (P=0.515). There was a significant decrease in pulse rate in the lavender (P=0.004) and orange (P=0.011) groups. The decrease in the control group was not significant (P=0.900). There was a significant decrease in VAS pain scores in the lavender and orange groups with each (P<0.001), whereas, in the control group, there was an increase in VAS pain scores.
Conclusion: Aromatherapy effectively controls anxiety, respiration rate, pulse, and pain in bronchoscopy patients.

Authors: Yarov Yuriy Yu. , Tkachenko Irina I. , Skripnikov Petro P. , Pavlenkova Olena O. , Pavlenko Svitlana S.
Published: October 2023

The aim is to study the dynamics of prostaglandins and cytokines in the blood and gingival fluid against the background of differential drug correction in patients with generalized periodontitis with different body reactivity.
Materials and methods: 216 people aged 45 between 55 years with a diagnosis of generalized periodontitis of II, III degree of severity, chronic course were examined. Depending on the state of reactivity of the organism, the patients were divided into three groups: the first one consisted of people with normoreaction; the second group included patients with hyperreaction; the third group was made up of people with hyporeaction. The patients underwent patch surgery after the initial therapy. Initially, on the 1st, 2nd, 4th, 6th and 9th day after the operation, the content of prostaglandins (PG) E, E2, F2alpha and cytokines (IL-1β, IL-6, TNF, IL-4) in the blood and gingival fluid was performed. Patients with impaired body reactivity were treated with the proposed differential drug correction of cytokines and prostaglandins. Statistical processing of the obtained digital data was performed using the computer program Statistica 8.0.
Results: The proposed differential drug correction in patients with generalized periodontitis against the background of hyper- and hyporeactivity of the body brings the content of IL-1β, IL-6, TNF, IL-4 to that of normal body reactivity, which ultimately restores the disturbed balance of pro- and anti-inflammatory cytokines in the blood and gingival fluid. On the 9th day, the content of all proinflammatory cytokines in the main groups was normalized and was commensurate with that of the body’s normal response (p>0.05). Differential drug correction led to normalization of the prostaglandin balance index on day 9 after flap surgery (p>0.05), indicating the establishment of a normal balance of eicosanoids in the blood and approximating the values of pro- and anti-inflammatory fractions of prostaglandins to those of normal body reactivity.
Conclusion: Correction of altered parameters in patients with generalized periodontitis accompanied by impaired (hyper- and hypo-) reactivity of the body with bringing them to values that are typical for normoreactivity is considered to be a condition for optimizing mucosal wound healing after surgery and further stabilization of periodontal tissues.

tiempo principia en Xibalbá», de Luis de Lión
Authors: Arce Oses Sebastián
Published: October 2023

Se aborda la novela El tiempo principia en Xibalbá, de Luis de Lión, como una práctica de espacio a través del análisis de la constitución espacio/temporal a partir de la cosmovisión maya. Gracias al trasfondo cultural sobre el que se asienta esta novela, hay una fuerte vinculación de las representaciones y semantizaciones del espacio físico, del tiempo, del movimiento y de los personajes, pues los mayas tienen una concepción cíclica y de reconstrucciones que los apartan de la linealidad occidental cristiana. Aunque el plano narrativo parte de la voz del pueblo indígena como centro, en el imaginario expresado se marcan posturas fuertes en la oposición entre el indio y el ladino, en donde el desencuentro y la violencia tornan imposible un espacio de diálogo entre ambos mundos. Estos desencuentros se manifiestan principalmente en las prácticas religiosas, la sexualidad, la violencia, el racismo y la percepción de la belleza.
novelas de Sergio Ramírez
Authors: Besse Nathalie
Published: October 2023

Sergio Ramírez resulta ser un escritor imprescindible en las narrativas del istmo, singularmente interesante además por su doble itinerario, literario y político. De hecho, sus novelas, en las que el poder aparece como un tema central y estructural, son posibles respuestas de la literatura al poder político, entre referencias extraliterarias e imaginarios propios de la ficción. Se tratará de estudiar primero las figuras del poder, sus modalidades novelescas que, entre abusos, corrupción y muerte, conforman un poder degradado, cuando no ridiculizado mediante una tonalidad discursiva esencialmente satírica cuya función crítica resulta evidente. Nos interesaremos luego en los procedimientos narrativos relacionados con el poder que deconstruyen la trama, el género, el relato mismo y la noción de verdad objetiva y única. Nos preguntaremos finalmente en qué medida Sergio Ramírez revela frente al poder una ética de la escritura, en tanto contradiscurso e implicación, ¿es decir una escritura actuante?

Authors: Akter Rima , Khan Md. Ashikur Rahman , Rahman Fardowsi , Soheli Sultana Jahan , Suha Nusrat Jahan
Published: October 2023

Cloud computing security has become the most crucial problem in its growth. Encryption has been developed as a solution and plays a vital role in the security of information systems in cloud computing. Many methods are required to secure the shared data. The advanced internet, networking firms, health information, and cloud applications have significantly increased our data every minute. The current work focuses on cryptography to protect sensitive data exchanged between personal users, companies, organizations, or in the cloud applications and others during data transfer across the network. Firstly, data sent from the sender to the network receiver must be encrypted using the cryptographic algorithm. Secondly, the recipient shows the original data using the decryption technique. In this paper, we have proposed a model to use a hybrid encryption and decryption process based on AES-128 and the RSA algorithm. Furthermore, we used the HMAC algorithm to ensure the integrity and authenticity of data. Our experiment work has been done to explain the time required and throughput for encryption and decryption of three encrypting algorithms, AES, RSA, and hybrid algorithms, based on different data sizes, and their efficiency is compared. The results of the experiments show that the hybrid algorithm is better in terms of security.

Authors: Bicak Besim Enes , Hattermann Mathias , Hübner Clara
Published: October 2023

Das Thema Digitalisierung und die Verwendung digitaler Medien in Schule und Unterricht erfährt innerhalb der letzten Jahre ein stetig steigendes Interesse in Forschung und Politik. Im Zuge der Coronapandemie haben diese Themenfelder auch in der allgemeinen öffentlichen Wahrnehmung nochmals an Bedeutung gewonnen. Dieser Beitrag präsentiert eine Fragebogenstudie, in der Lehrkräfte (n = 151) aus der Region Braunschweig über ihr Nutzungsverhalten digitaler Medien befragt wurden. So kann ein Überblick über die Nutzung bestimmter Hard- und Software, die Einstellung der Lehrkräfte zur Verwendung digitaler Medien und das digitale Selbstkonzept der befragten Lehrkräfte gegeben werden. Es ist zu konstatieren, dass die befragten Lehrkräfte eine sehr positive Einstellung zu digitalen Medien besitzen und sich ihr Hard- und Softwarerepertoire durch die Coronapandemie erweiterte. Für die jüngeren Lehrkräfte zeigt sich darüber hinaus, dass die Thematisierung der Nutzung von digitalen Medien in Studium und Referendariat erfolgt, aber weiter ausgebaut werden sollte.

Hier geht es um eine mathematische Fragestellung, die sich elementar formulieren lässt, aber nur schwer, oder gar nicht, vollständig zu beantworten ist. n Steine sollen so auf die Kacheln einer Zerlegung der Ebene in Quadrate gelegt werden, dass in jeder Reihe und jeder Zeile gerade viele Steine liegen. Es ist ganz erstaunlich, welche Reichhaltigkeit an mathematischen Themen sich ergeben, wenn man dieses Problem untersucht.
Rhombenfiguren
Authors: Walser Hans
Published: October 2023

Wir verwenden Rhomben als Bauteile für zusammengesetzte Figuren in der Ebene und im Raum. Zunächst arbeiten wir mit Rhomben, die alle die gleichen Winkel haben, die also zueinander ähnlich sind. Dies ermöglicht Verallgemeinerungen von Sätzen der Elementargeometrie. Wir finden eine struktursymmetrische Schließungsfigur und erhalten eine neue Sicht auf den Satz des Pythagoras. Anschließend verwenden wir Rhomben, die alle die gleiche Seitenlänge haben. Damit schaffen wir den Übergang von der Ebene in den Raum. Wir konstruieren einen Rhombenkörper, der die Kosinusspindel approximiert.

Authors: Igben Harvey G.O. , Adebayo Rhoda Giddijios
Published: October 2023

The study explored the influence of Mass Communication collaboration on research outcomes in selected universities in the South-South of Nigeria. The paper observed that the influence of research collaboration amongst Mass Communication scholars was high. The most influential factors to collaborative research practice were enhanced team approach in research and the generation of new insights or perceptions that individuals working on their own may not have been able to achieve. The issue of internet connectivity, difficulty in working with colleagues in research as many of them may not be able to contribute anything, and being afraid of inadequate contribution by co-authors were the most established drawbacks discovered in this study. The study recommended that there should be research collaboration that is anchored on the necessary atmosphere that will make the exercise worthwhile by institutions of learning.

A Full and Detailed Proof for the Riemann Hypothesis & the Simple Inductive proof of Goldbach’s Conjecture
Authors: Shun Lam Kai
Published: October 2023

As in my previous two papers [2] & [3] about the boundary of the prime gap still cause some misunderstanding, I here in this paper tries to clarify those detailed steps in proving such boundary of the prime gap for a contradiction. Indeed, the general idea of my designed proof is to make all of the feasible case of the Riemann Zeta function with exponents ranged from 1 to s = u + v*I becomes nonsense (where u, v are real numbers with I is imaginary equals to (-1)1/2 except that u = 0.5 with some real numbers v as the expected zeta roots. Once if we can exclude all other possibilies unless u = 0.5 with some real numbers v in the Riemann Zeta function’s exponent “s”, then the Riemann Hypothesis will be proved immediately. The truth of the hypothesis further implies that there is a need for the shift from the line x = 0 to the line x = 0.5 as all of the zeta roots lie on it. However, NOT all of the points on x = 0.5 are zeros as we may find from the model equation that has been well established in [2]. One of my application is in the quantum filtering for an elimination of noise in a quantum system but NOT used to filter human beings like the political counter-parts.In general, this author suggests that for all of the proof or disproof to any cases of hypothesis, one may need to point out those logical contradictions [14] among them. Actually, my proposition works very well for the cases in my disproof of Continuum Hypothesis [15] together with the proof in Riemann Hypothesis

Published: October 2023

A ludicidade é um tema importante e necessário no contexto escolar. Ao abordar este tema, remete-se imediatamente aos jogos e brincadeiras. De fato, estes termos interligados à ludicidade pois é através dos jogos e brincadeiras que a criança, de um modo simbólico, expressa seus desejos e suas fantasias. É através deles também que fluem a criatividade e a imaginação infantil. Desse modo, valer-se da ludicidade no ambiente escolar proporciona uma aprendizagem prazerosa e significativa. Além disso, a utilização de jogos e brincadeiras oportunizam à criança o contato com situações nas quais deverá lidar com regras, o que favorecerá sua autonomia. Este artigo aborda também a Educação Especial, uma modalidade de educação oferecida preferencialmente no ensino regular e que tem como clientela alunos com deficiência, transtornos globais do desenvolvimento e altas habilidades. Pensar a Educação Especial leva a reflexão de que maneira esta educação pode caracterizar-se como inclusiva, uma educação que assegure acesso e permanência de todos em qualquer modalidade de ensino. Desse modo, o tema A Ludicidade no contexto da Educação Especial Inclusiva aqui explanado, tem como objetivo geral refletir sobre a importância da ludicidade para a inclusão dentro do contexto da Educação Especial. Para tal utiliza a pesquisa bibliográfica serão reunidas informações que respondam também aos objetivos específicos que são: compreender o conceito de ludicidade; conhecer as leis que norteiam a Educação Especial Inclusiva e compreender de que maneira a ludicidade pode ser usada como recurso pedagógico na Educação Especial Inclusiva. A pesquisa comprova que a ludicidade é um recurso importante já que brincar é inerente ao ser humano. Ao brincar a criança elabora estratégias que mais tarde serão utilizadas em seu cotidiano, além é claro de estimular a criatividade.

A pesquisa intitulada A Filosofia como exercício espiritual em Pierre Hadot: Repensando o ensino filosófico com vistas à autonomia e à emancipação intelectual de alunos no ensino médio alcança o tema referente aos objetivos da educação básica brasileira na atualidade e, em específico, o espaço destinado à filosofia e ao seu ensino sob o prisma da emancipação. Diante de um problema apresentado a partir da experiência do professor-pesquisador, esta investigação passou a admitir a hipótese de uma determinada filosofia, considerada modo de vida e explicitada por meio dos chamados exercícios espirituais, contribuir para a autonomia e para a emancipação intelectual dos sujeitos, graças à (trans) formação que eles podem ensejar”. Para enfrentar a questão-problema, propôs-se uma revisão de literatura que permitiu uma aproximação entre conceitos filosóficos extraídos do pensamento de Pierre Hadot, na obra Exercícios Espirituais e Filosofia Antiga (2014a), com outras ideias encontradas em O mestre ignorante – cinco lições sobre a emancipação intelectual (2002), de Jacques Rancière, sem deixar de lado o aporte de outros pensadores, como Michel Foucault e Walter Omar Kohan. A investigação, estruturada sob a forma de uma pesquisa-ação em virtude do intento de solucionar ou amenizar a situação descrita, se debruçou sobre a compreensão de conceitos-chave, como os de exercícios espirituais e emancipação intelectual para, a partir deles, discutir a possibilidade e a viabilidade de alguns exercícios espirituais contribuírem para a autonomia dos sujeitos, no caso específico, de alunos e alunas da primeira série do novo ensino médio da educação básica, objetivo principal do estudo. A relação teoria/empiria foi evidenciada por meio de uma ação educativo-filosófica executada na Escola Estadual Querubina Silveira, em Cerro Corá/RN, cujos procedimentos se pautaram na articulação entre os conceitos trazidos na pesquisa e as ações e pensamentos dos(as) alunos(as) integrantes do estudo, os(as) quais foram submetidos(as) às práticas espirituais de Pierre Hadot. Dessa experiência, foram construídos os dados necessários para a fase seguinte: a análise dos resultados. Em sede conclusiva, observamos a possibilidade de um reposicionamento da filosofia no contexto escolar e o seu fortalecimento graças ao protagonismo dos(as) estudantes durante a investigação e, sobretudo, devido às reflexões oportunizadas pelas práticas realizadas nas sessões/aulas da ação educativo-filosófica, somadas ao surgimento de novos olhares acerca dos temas trazidos à discussão, culminando em uma verdadeira experiência filosófica. Em linhas gerais, esta investigação se apresentou como instrumento para compreensão da realidade educacional brasileira, no que toca especificadamente ao ensino filosófico, e para a transformação não só da situação-problema descrita.

Objetivo: O objetivo do estudo foi quantificar as variações morfométricas de frutos e pirênios de Syagrus coronata, de diferentes habitats (natural e manejado) e explorar as relações com a predação. Métodos: Para condução do estudo foram coletados 600 frutos em cada habitat. Os frutos e pirênios foram mensurados através do tamanho (comprimento, largura e espessura) e peso. Avaliou-se também a massa corporal do predador a fim de analisar a relação deste com as medidas morfológicas dos frutos. Resultados: Frutos e pirênios de hábitat natural apresentaram maiores valores, tanto para medidas associadas à morfologia quanto para o peso, destacando que há mais recurso disponível para seu desenvolvimento, o que os torna mais vigorosos. A maior taxa de predação foi para os pirênios coletados em habitat natural, que por exibirem vigorosidade, tornaram-se preferência do predador devido à riqueza nutritiva. Essa condição expõe compatibilidade com estratégia de sobrevivência e reprodução da fêmea, além de tornar-se um facilitador para o ataque por parte de P. nucleorum. Quanto à massa corporal do predador, houve seletividade associada às medidas morfológicas referentes a comprimento e espessura, com correlação positiva. Conclusão: A escolha do predador é por frutos mais vigorosos, indicando maior disponibilidade de recurso para sobrevivência e desenvolvimento da prole. Espera-se que com este estudo possa haver melhor compreensão para a conservação da população de Syagrus coronata, como o entendimento dos efeitos da ocorrência da modificação por parte de atividades antrópicas na cobertura vegetal da Caatinga.
Large Eddy Simulation of Hydrogen/Natural Gas/Air Premixed Swirling Flames and CIVB Flashback Risks

Published: October 2023

The desire to develop gas turbines (GTs) that can utilise natural gas (NG) blended with hydrogen (H2) often encounters operability challenges related to combustion-induced vortex breakdown (CIVB) flashback issues. Hence, a detailed Large Eddy Simulation (LES) was employed in this study to examine the impact of H2-NG co-firing on central recirculation zones (CRZs), combustion properties, and the risk of CIVB flashback in a pilot-scale swirl burner facility. The LES model successfully replicated the swirling component of the flame observed in the experiment with reasonable accuracy. The findings revealed that the introduction of H2 into the burner increased the velocity and temperature of the burned gases. The higher reactivity of H2 resulted in faster burning rates and a shift in the reaction zone, indicating that NG-H2 firing burns more rapidly than pure NG firing. Additionally, H2 was found to enhance the velocity gradient, pushing the CRZ upstream. Changes in the location of the CRZ can disrupt density and velocity gradients, affecting the generation of vorticity by the baroclinic torque and potentially increasing negative axial velocity, thereby increasing the risk of CIVB flashback. Further research is necessary to comprehensively assess the CIVB flashback risk, particularly when the proportion of H2 exceeds 30 %.

AbstractPersyaratan Umum Instalasi Listrik (PUIL) are requirements that must be met in electrical installations. The application of the PUIL standard in electrical installations is very important in order to avoid unwanted things due to errors in electrical installations such as fire. West Aceh State Community Academy, which is a vocational college, really needs electricity to operate practicum equipment. If the electrical installation at the Aceh Barat State Community Academy does not meet PUIL standards, it is very vulnerable that the practicum equipment will be damaged quickly and even a fire occurs because the practicum equipment requires a fairly large amount of electrical power. The purpose of this study was to analyze the suitability of the Kuat Hantar Arus (KHA) in the electrical installation conductors of the West Aceh State Community College based on the 2011 PUIL standards. The research method used was the method of literature study and field observation. The results showed that in general the KHA conducting electrical installations at the West Aceh State Community Academy which was divided into 10 lines was very good where 2 lines were in accordance with the standards and 8 lines were above the 2011 PUIL standards. Keywords:PUIL 2011; Electrical Installation; Strong Conducting Current..__________________________ AbstrakPersyaratan Umum Instalasi Listrik (PUIL) merupakan persyaratan yang harus dipenuhi pada instalasi listrik.
