Authors: José Cherem Jorge , Testoni André Filipe , Valler Ícaro William , Althoff Sérgio Luiz
Published: January 2022

As florestas estacionais são ecossistemas marcados por grande sazonalidade climática, que ocorrem na região tropical em todo o mundo e estão associadas aos vários biomas brasileiros. Apesar do clima subtropical, estas florestas também ocorrem no sul do Brasil, na calha do rio Uruguai e seus principais afluentes, uma região ainda carente em estudos sobre a fauna. Neste sentido, apresentam-se aqui os resultados obtidos com o levantamento da mastofauna durante a etapa de implantação da Usina Hidrelétrica Foz do Chapecó, na divisa entre os estados de Santa Catarina e Rio Grande do Sul, no período de setembro de 2007 a junho de 2010. Foram empregados os métodos de observação direta, levantamento de vestígios e atropelamentos, armadilhas fotográficas, captura de pequenos mamíferos com armadilhas de arame e chapa de alumínio e com armadilhas de interceptação e queda, captura de morcegos com redes de neblina, busca por colônias e entrevistas. Foram registradas 68 espécies, pertencentes a 22 famílias e nove ordens de mamíferos, incluindo 16 espécies ameaçadas e duas exóticas. A riqueza de pequenos mamíferos foi relativamente alta. Akodon spp. e Oligoryzomys nigripes foram as espécies mais abundantes entre os não voadores, e Sturnira lilium e Artibeus spp. entre os morcegos. Várias espécies de médio e grande porte registradas são raras ou estão extintas localmente. Esses dados possivelmente refletem os impactos da grande perda de cobertura floresta e da pressão caça, cuja mitigação é fundamental para conservação da biota regional.
Alteração cromática em Alouatta guariba clamitans Cabrera, 1940 no estado de Santa Catarina, sul do Brasil
Authors: Meyer Douglas
Published: January 2022

Alteração cromática na pelagem de bugios ainda é um evento raro, podendo estar relacionado à fragmentação florestal que isola as populações da espécie, favorecendo a endogamia, e ao uso intensivo de pesticidas à base de enxofre, acumulados durante a alimentação. Um indivíduo com alteração cromática - pelagem amarelada - foi registrado compondo um grupo de cinco indivíduos no sul de Santa Catarina. Relatos sobre o assunto são importantes para estudos de ecologia e deverão estabelecer bases para o conhecimento da frequência com que essas alterações aparecem em indivíduos na natureza e como o indivíduo é afetado.

Abstract:

This research is oriented to analyze the use of Youtube as a learning media of religious tolerance for virtual communities. The focus of the research is on the "jeda nulis" youtube channel with the content "toleran dalam berdakwah, dakwahkan toleransi." This research was conducted based on the reality of the rise of radical Islamic accounts that spread negative content in the form of teachings that are easy to disbelieve and convert to those who have different understandings and traditions. This research is descriptive-qualitative with a literature study approach. To explore the data obtained by watching and analyzing videos on related content. The results of the study found that Youtube can be used as a medium to spread the teachings of religious tolerance. In the youtube content mentioned above, Habib Husein collaborated with Christian and Buddhist religious figures, the three figures succeeded in bringing religious narratives that made virtual communities aware to better understand and apply the teachings of religious tolerance. religion is tolerance, but its people cannot necessarily be tolerant.  The three religious leaders agreed that ego, lust, and group fanaticism must be eliminated in humans in order to be tolerant. If someone cannot become a brother in faith, then compete in goodness in the name of humanity. Because the real enemy for someone is itself so that must be clear first.

Published: January 2022

Blood supply is an important part that is very influential on health because almost all blood types are necessary for medical activities. This condition makes blood management very important, but improper blood management can cause a waste that results in huge final costs and causes losses for both the customer and the blood supplier. In this case, Monte Carlo simulation can be used to develop several policies that can optimize blood inventory levels and minimize inventory costs at Indonesian Red Cross XYZ. In this simulation, input data required are blood donor supply and Packed Red cells (PRC) demand data, this data will be used to determine the shortage and expired rate. From simulation will be obtained shortage rate of 33 blood bags and an expired rate of 75 blood bags with inventory cost Rp. 36,226,964. Monte Carlo simulation will make new policy rules with increasing the supply of whole blood (WB) which will be used as a component of the PRC and reducing the supply level. From these simulation results, the best policy will gain and applied at PMI XYZ to optimize inventory cost.
La autonomía de las universidades chilenas para sancionar hechos de violencia contra las mujeres
Authors: Iuspa Santelices Carla
Published: January 2022

El presente trabajo analiza las consideraciones de la Corte Suprema chilena suscitadas al alero de la reciente normativa universitaria en materia de acoso sexual y otras formas de violencia en contra de las mujeres. Se sostiene que la tesis sostenida por el máximo tribunal chileno (replicada por algunas Cortes de Apelaciones) adolece de una ceguera importante frente a las desigualdades de género que subyacen a los fenómenos de acoso y violencia en contra de las mujeres y que fundamentan la institucionalidad universitaria en la materia. Para ello, se analiza desde una perspectiva de género la forma de reconstruir la autonomía universitaria para sancionar dichos hechos y se contrasta con otros pronunciamientos de la Corte en que se otorga una mayor amplitud a la potestad sancionatoria de las universidades en el marco regulatorio chileno.

Authors: Gaiger Luiz , Wanderley Fernanda
Published: January 2022

El articulo sintetiza los resultados de una investigación internacional, abarcando América Latina, y tiene por objetivo presentar los principales tipos de organizaciones económicas no determinadas exclusivamente por la lógica del mercado y de las empresas capitalistas, y en algunos casos en conflicto con las mismas. Siete patrones de organizaciones alternativas son identificados, con sus respectivos contextos y trayectorias de diseminación e institucionalización, las cuales originaron formas de actuación económica distintas a las típicamente capitalistas, como la economía comunitaria, popular, cooperativa y solidaria. El análisis se apoya en investigaciones nacionales con base en revisiones bibliográficas, análisis estadísticos, estudios de caso y cuestionarios aplicados en los sectores más relevantes. En conclusión, el documento resalta el papel central desempeñado por el paradigma cooperativo en la región y al hecho de que las organizaciones alternativas funcionan como factores de contención de la lógica de mercado y de preservación de colectividades cuyo sistema de vida se funda en otros principios económicos, especialmente el de la reciprocidad.
PHYSICAL-MECHANICAL PROPERTIES OF NANOCOMPOSITES BASED ON GRAPHITE AND MODIFIED POLYOLEFINS
Authors:   Institute of Polymer Materials of the National Academy of Sciences of Azerbaijan, Allahverdiyeva Kh.V.
Published: January 2022

The influence of the graphite concentration on the main physical-mechanical properties of nanocomposites based on such polyolefin as high density polyethylene, low density polyethylene and polypropylene is considered. Properties such as tensile yield stress, ultimate tensile stress, and ultimate bending strength, elongation at break, heat resistance, flexural strength, MFI, and melting points are analysed. To improve the compatibility of the mixed components of the mixture, we used an Exxelor PO1040 compatibilizer for all grades of polyethylene and Exxelor PO1020 for polypropylene. Graphite was introduced into the composition of polyolefin at the following concentrations: 1.0, 3.0, 5.0, 10, 15, 20, and 30 wt%. As a result of the research, it was found that the introduction of graphite into the composition of polyolefin was accompanied by an improvement in strength characteristics with maximum at various concentrations. For high density polyethylene, the maximum values of strength characteristics are observed at 3.0 wt%, for low density polyethylene at 10 wt%, and for polypropylene at 5.0 wt% content of graphite. It revealed that such a difference in the value of the threshold concentration of graphite which provides the maximum value of strength indicators,was directly related to the degree of crystallinity of the polymer matrix.
A szerződés érvénytelensége mint jogvédelmi eszköz
Authors: Menyhárd Attila
Published: January 2022

A szerződés érvénytelensége a társadalmi cselekvés korlátja, és kevésbé szankció. E korlát célja köz- vagy magánérdekek védelme. Az érvénytelen szerződés társadalmi kapcsolat, így az érvénytelenség következményei az érvénytelenség társadalmi hatásairól szólnak. Az érvénytelenség következményeinek a szabályai a magyar szerződési jogban extenzív állami beavatkozást jelentenek és jól illeszkednek abba a folyamatba, amely megkérdőjelezi a szerződési szabadságra épülő hagyományos szerződési modell fenntarthatóságát. Az eredeti állapot helyreállítása vagy az értékbeli restitúció a szerződési szabadság és a magánautonómia védelmét preferáló megoldás. Ezzel szemben a bírósági szerződésmódosítással való érvényessé tétel paternalista megközelítést tükröz, és ez vonatkozik a részleges érvénytelenség szabályaira is. A bíróság ezekben az esetekben voltaképpen az egyik fél érdekeit védi meg a másik féllel szemben. Ezeket a sajátosságokat és hatásokat elemzi részletesen a tanulmány.
„Érvénytelenségi határkérdések” – úszó határok az érvénytelenség és hatálytalanság problémakörében
Authors: Leszkoven László
Published: January 2022

A tanulmány a polgári jogi érvénytelenség és hatálytalanság jogintézményeinek alapvető, fogalmi kérdéseivel foglalkozik. Az „úszó határok” kifejezés a fogalmak közötti átmenetet, az elhatárolás elmosódottságát hivatott érzékeltetni. A tanulmányban kitérünk a „nem létező” (non existens) szerződések kérdéseire, röviden bemutatva az elméleti és a gyakorlati reakciókat. Áttekintjük a két fogalom kombinációjaként előálló egyes jogi jelenségek közül a legfontosabbakat, elsősorban a relatív hatálytalanság esetköreit, például a fedezetelvonó szerződés (actio Pauliana) és az elővásárlási jog megsértése miatti személyi hatálytalanság esetét. Kitérünk a generálklauzulákon keresztüli szabályozás néhány jellemzőjére, ebben a vonatkozásban a jóerkölcsbe ütköző szerződés semmisségi tényállásának a polgári jog alapelveivel, elsősorban a jóhiszeműség és tisztesség (Treu und Glauben) elvével való kapcsolatára mutatunk rá.
Az érvénytelenség és a szerződésszegés összefüggéseiről
Authors: Nochta Tibor
Published: January 2022

A tanulmányban felvázolt tézisek alapján azt a következtetést vonhatjuk le, hogy az érvénytelenség és a szerződésszegés intézményei, mint a magánjogi jogellenesség fontos esetei, egymással összefüggenek, egymásra hatással vannak, amely fontos irányokat szab az elmélet, a jogalkotás és a joggyakorlat számára egyaránt. A szerződés ezen létszakaszait nem lehetséges izoláltan kezelni, ugyanakkor az elhatárolások fontosságára is figyelemmel kell lennie az elméletnek és a bírói gyakorlatnak.
Az akarati hiba miatti jognyilatkozat és az általános szerződési feltétel, valamint az annak alapján kötött munkaszerződés megtámadását érintő munkajogi szabályozás problémája
Authors: Prugberger Tamás
Published: January 2022

A tanulmány két témakört ölel fel. Az első azzal a diszkriminatív kettősséggel foglalkozik, ami abból ered, hogy a Munka Törvénykönyv a munkaviszonnyal kapcsolatos kötelezettségvállalási nyilatkozatát kényszer, fenyegetés, tévedés vagy megtévesztés esetében a Polgári Törvénykönyv szerződésmegtámadási határidővel szemben egész rövid határidőn belül támadhatja csak meg. A szerző szerint semmi sem indokolja a speciális, rövid munkajogi megtámadási határidőt. A másik témakörben a szerző azt veti fel, hogy a munkaszerződést többnyire előre gyártott blankettán kötik meg, ezért a fogyasztói szerződésekhez hasonlóan kellene kezelni a foglalkoztatással kapcsolatos jogügyleteket, kiterjesztve a blanketta munkaszerződésekre is a közérdekű kereset (polularis actio) lehetőségét.
Harmadik államok imperatív szabályai, mint a szerződés érvényességét befolyásoló tényező
Authors: Palásti Gábor Péter
Published: January 2022

A több ország jogához is kapcsolódó szerződések esetén gyakori a többjogúság jelensége, amikor az egyes jogkérdésekre az elsődlegesen alkalmazandó jog szabályai mellett más államok jogrendszerei is hatással vannak. Ilyen esetkör az imperatív szabályok köre (az EU-ban lásd a szerződések kapcsolóelveit egységesítő Róma I. rendelet 9. cikkét). A tanulmány annak a kérdését járja körül, hogy harmadik államok imperatív szabályai hogyan befolyásolják többek között a szerződések érvényességét, mind elméleti, mind gyakorlati szempontból.
Az értékaránytalanság, mint érvénytelenségi ok a családtagok vagyonjogi szerződéseiben
Authors: Kriston Edit
Published: January 2022

A családtagok vagyonjogi szerződései sajátos helyet foglalnak el a kontraktusok világában. A vonatkozó jogszabályi rendelkezések komplex rendszert alkotnak, hiszen egyfelől a családjogi normák, másrészt a kötelmi jog általános előírásai irányadóak. A szerződések tartalma kapcsán a szerződési szabadság teljeskörűen érvényesül, ugyanakkor mégis találkozunk különböző korlátokkal. Az egyik ilyen korlát éppen a szerződések érvénytelenségének megítélése. Jelen tanulmányban arra helyezem a hangsúlyt, hogy a családtagok vagyonjogi kontraktusainak érvénytelenségét kifejezetten csak az értékarányosság szempontjából vizsgáljam.
Az ajánlat hatálytalansága és érvénytelensége a közbeszerzési jogban
Authors: Máté Gergő
Published: January 2022

A közbeszerzési jog alapvető elemének, az ajánlat fogalmának mélyebb megértését teszi lehetővé érvénytelenségének, illetve hatálytalanságának megfelelő elhatárolása, amely végső soron az ajánlat eljárásjogi létezésének kérdését veti fel. A tanulmány azt az általános elméleti következtetést vonja le az ajánlat példáján keresztül, hogy a jog(ügylet)i létezés (vagy nemlétezés) megállapítása egyrészt önálló, másrészt elsődleges döntést feltételez az érvényességének vagy érvénytelenségének megállapítását megelőzően.
Az érvénytelenség további jogkövetkezményei, különös tekintettel az árfolyamkockázat fogyasztóra telepítése tisztességtelenségének megállapítása esetén alkalmazandó jogkövetkezményekre
Authors: Pomeisl András József
Published: January 2022

A tanulmány a deviza alapú fogyasztói kölcsönszerződés érvénytelenségének megállapítása esetén alkalmazandó jogkövetkezmények problémáját vizsgálja. Áttekinti az alkalmazandó jogkövetkezmények kiválasztásának általános szempontjait a hazai jogban. Rámutat a tisztességtelenség fogalmi elemeinek jelentőségére, és az Európai Unió Bíróságának joggyakorlata alapján összegzi a 93/13/EGK irányelv 6. és 7. cikkéből fakadó követelményeket. Végül a mellett érvel, hogy a Kúria elnöke által felállított Konzultatív Testület által javasolt két megoldás lényegében egyenértékű.

Published: January 2022

Historical masonry structures that connecting the past to the present have great importance because they represent the experiences and characteristics of various cultures. Therefore, the protection of historical structures is important. In this study, the structural response of the historical masonry Mosque was evaluated through dynamic analyses. For this purpose, the Sütlü Minaret Mosque which is located in Malatya, Turkey, was investigated. The three-dimensional model of the historical mosque was generated with ANSYS software. The material properties of the mosque were obtained with experimental tests. The time history analyses were used to obtain the seismic behavior of masonry mosque. In the time history analyses, six different strong ground motion records, including the 2020 Elazığ earthquake, were used. After the analysis, displacement and stress values in the mosque were given. The absolute peak displacement value among these earthquake records was obtained from the 1999 Düzce earthquake and the highest principal compressive and tensile stress values were determined for the 2010 Darfield earthquake. Also, the crack regions which occurred in the mosque after the 2020 Elazığ earthquake were compared with the dynamic analysis result of the 2020 Elazığ earthquake. The crack regions formed after the Elazığ earthquake are similar to the possible crack regions formed after the dynamic analysis.
El primer proyecto gótico de Santa Maria de Castelló d’Empúries
Authors: Boto Gerardo
Published: January 2022

Resumen: Este estudio presenta un meticuloso análisis de la iglesia de Santa Maria de Castelló d’Empúries, sin duda uno de los edificios más originales y portentosos del primer gótico en Cataluña. Explicitando los objetivos, metodologías e hipótesis de trabajo, se disecciona su proceso constructivo, particularmente su primera fase, argumentando los fundamentos de una nueva interpretación, de modo que se superan hipótesis precedentes. Atendiendo a evidencias que han pasado desapercibidas, se propone una acotación cronológica para esta fase del edificio ca. 1261–1290. Del mismo modo, se identifican los referentes arquitectónicos de la fábrica de Castelló d’Empúries, que explicitan el currículum formativo del maestro responsable del primer proyecto constructivo, que hay que identificar con Reinald de Chartres. Los perfiles de esta personalidad artística son reconocibles a partir de la comprensión de los detalles más elocuentes y fundamentales de la fábrica. Se establece una perspectiva internacional, desde el gótico rayonnant de mediados del siglo XIII, para la iglesia de Santa Maria, deslindable del resto de la producción arquitectónica catalana del siglo XIII y primera mitad del XIV.

 

Abstract: This study offers a detailed analysis of the church of Santa Maria de Castelló d’Empúries, undoubtedly one of the most original and portentous early Gothic buildings in Catalonia. The main objective of this text is to dissect the construction process of Santa Maria, especially its  first phase, according to a methodology that focuses on the material analysis and documentary understanding of the church. Taking into account unnoticed particulars, it argues for a new interpretation that goes beyond previous hypotheses. Through material evidences, this study proposes a chronological estimation of the first project of the building to around 1261–1290, as well as its architectural references. These make explicit the architectural curriculum of the master responsible for the first construction project, who is to be identified as Reinald de Chartres. His artistic personality and technical skills are recognizable from the most eloquent and fundamental facts of the construction. The chronology and authorship of the building represent a significant change in perspective. From the Gothic style of the mid-13th century, an international perspective is established for the church of Santa Maria, which is distinguished from the rest of the architectural production in Catalonia during the 13th century and the first half of the 14th century.

Authors: Sabah Saed , Hammouri Hind , Akour Mutasem
Published: January 2022

The purpose of the present study was to validate a scale of attitudes toward science based on items and data of TIMSS 2007. The present research introduces several implications and recommendations for science education researchers who are interested in validating and using instruments to measure attitudes toward science. This research examined, from Rasch measurement perspectives, to what extent the scale was valid across diverse participating countries from Rasch measurement perspectives. The data of the highest three achieving countries (Singapore, Taiwan, and Japan), the lowest three achieving countries (Qatar, Botswana, and Ghana), and three average achieving countries (Australia, Scotland, and Italy) were analyzed using WINSTEPS software. Several Rasch analyses (e.g, fit statistics, PCA, and person/item map reliability analysis) were performed to validate the scale. Although most of the item fit the Rasch model, a few items were found to be misfitting. Then, the misfitting items were eliminated and a second analysis for the fitting eight items was performed to check on the validity of the scale. The results provided evidences that support the validity of the scale based on Rasch measurement. Key words: attitudes toward science, Rasch measurement, science education, validity.

Authors: Puhek Miro , Perše Matej , Vršnik Perše Tina , Šorgo Andrej
Published: January 2022

In the present research the results of 288 lower secondary schools in-service teachers, 192 undergraduate students and 211 lower secondary school students from Slovenia were analysed in terms of importance of fieldwork and the information and communication technology (ICT) as a solution for supporting or replacing fieldwork itself. The main aim of the analysis was to compare the points of view in all stages: from students to teachers. Also, comparisons with international data obtained as part of TIMSS and TALIS studies were made. The analysis showed that participants tend to acknowledge a very positive effect to this kind of learning, despite the obstacles connected therewith. A comparison of the usage of ICT at home and in the school environment, as predicted, showed that students tend to be more digitally competent than their teachers. Also, the statistically significant difference pointed out that older teachers are less favourable towards ICT in education than their younger colleagues.

Diabetic neuropathy (DN) is one of the main complications of diabetes mellitus (DM), responsible for a high morbimortality rate and burdening public health resources. Photobiomodulation has proven to be effective in relieving pain, reducing the inflammation, and improving vascularization. We report an evaluation of the effectiveness of photobiomodulation for the relief of pain and to improve the quality of life in patients with diabetic neuropathy. A total of 30 diabetic volunteers with DN were randomly divided into three groups: control, photobiomodulation (PBM), and placebo (P-PBM). Those in Group control were instructed to take diabetic neuropathy medication for 30 days. The PBM group received laser photobiomodulation treatment with the following protocol: three sessions per week for 30 days, totaling 12 applications (wavelength, 808 nm; energy density, 12 J/cm²). in the of following nerves: tibial medial plantar, own plantar digital, common plantar digital, superficial fibular, deep fibular, sciatic, saphenous, and common fibular. Patients in the P-PBM Group were submitted to the PBM protocol, but with the device switched off. Before and after applying the therapeutic protocols, all volunteers were subjected to pain evaluations. The results showed a statistically significant difference between the groups (p < 0.05). The PBM group confirmed an analgesic effect directly related to the use of the photobiomodulation, whilst the patients in group control and P-PBM, did not present significant results. The study demonstrated that laser photobiomodulation is effective in significantly reducing pain and improving the quality of life of patients with diabetic neuropathy.

Objetivo: Descrever os cuidados do enfermeiro a criança na sessão de hemodiálise. Metodologia: Trata-se de uma revisão de literatura, de abordagem qualitativa. Foram utilizados oito artigos disponíveis nas bases de dados LILACS, MEDLINE e BDENF, escritos em português e publicados no período de 2010 a 2021. Para analisar os artigos selecionados, foram criados dois quadros: O Quadro 1 que traz o nº, título, autor, ano, periódico e base de dados, e o Quadro 2, que traz o n°, título, objetivo e principais resultados. Resultados: Dos artigos encontrados, poucos abordam sobre a criança, o que demonstra que ainda é muito limitado os estudos relacionados ao tema, justificando o escasso número de artigos que compuseram a amostra final. Observou-se a prevalência das temáticas: qualidade de vida e assistência do enfermeiro a pacientes em hemodiálise. De uma forma geral, os estudos trazem que o enfermeiro necessita ter grande conhecimento, sensibilidade e humanização, para saber lidar com tantas tecnologias e a parte administrativa, sem colocar em segundo plano o cuidado prestado a criança.  Conclusão: Conclui-se que o enfermeiro não pode ser apenas um realizador de cuidados técnicos ao paciente, ele precisa proporcionar um tratamento que seja menos traumático, minimizando o sofrimento causado à criança devido a sua enfermidade e tratamento. Através deste estudo, evidenciou-se a importância de futuros estudos na área de enfermagem em nefrologia pediátrica, principalmente no que tange os cuidados prestados a criança no tratamento hemodialítico, desde o momento da admissão até a saída.

A dor é uma experiência sensitiva e emocional desagradável associada a lesão tecidual real ou potencial; de natureza multifatorial e reconhecida como sério problema de saúde pública. Embora com diversos fármacos sintéticos empregados na terapêutica, é constatado crescente expansão no uso popular de plantas e produtos derivados no tratamento e/ou alívio da dor; situação que merece destaque pela perspectiva do uso popular possibilitar seleção de espécies vegetais para os estudos de validação, mas alertar também para riscos pois a utilização dos insumos vegetais para fins terapêuticos exige certificação de eficácia, segurança e qualidade. Assim, este trabalho objetiva realizar revisão dos estudos etnodirigidos de espécies vegetais utilizadas nas popuçarmente para tratamento da dor. A busca foi realizada nas bases Scielo, LILACS e Pubmed, incluindo artigos publicados de 2011 a 2021, usando como descritores: “dor”, “etnobotânica” e “fitoterapia”. Foram selecionados 66 artigos, com predomínio de publicações no Brasil e Índia, na língua inglesa; com 70 espécies vegetais referidas, pertencentes a 40 famílias, predominando Asteraceae (12,35%). As espécies mais referidas foram Curcuma longa L. (7,14%), Zingiber officinale Roscoe (5,71%) e Mentha x piperita (4,28%); predominando uso das folhas (54,54%), preparadas por decocção (15,15%) e extração aquosa (13,63%). Embora diversas espécies sejam usadas popularmente para tratamento de dor, ainda são escassos os estudos de segurança e eficácia para uso terapêutico. Essa revisão sinaliza espécies a serem selecionadas para prosseguimento com estudo de validação, visando contribuição na oferta de novas opções de tratamento para dor, mas desperta para necessidade de ações de Farmacovigilância em Fitoterapia.

Cancer is an important cause of lethality, and melanoma is associated with less than 10% of survival. The traditional treatment includes the use of vinblastine, and it is associated with side effects. Curcumin is extracted from Curcuma longa rhizomes, and studied in many diseases, producing a variety of effects. We investigated the role of various cellular pathways concerning apoptosis, cell cycle enzymes in melanoma cell line SK-MEL-28, after treatment with curcumin, vinblastine, or a combination of both, for 24 hours. After this, we performed cell cycle, apoptosis, wound healing assay, comet assay on cells, and evaluated nitrite accumulation (nitric oxide (NO•) byproduct). Curcumin increased cells in apoptosis and reduced the number of cells in the G1 phase. Vinblastine increased the production of nitrite, and cells in early apoptosis, mainly through the inducement of DNA damage. Cell migration was impaired in all tested groups. In conclusion, curcumin impaired migration, producing NO•, and promoting apoptosis of tumoral cells. Vinblastine also impaired cell migration and increased levels of NO•. Curcumin might be included as an adjuvant in the treatment of melanoma, and help treatment of melanoma, and further studies are needed, especially regarding the synergistic effect of curcumin and vinblastine in the treatment.

Published: January 2022

En este artículo analizamos los decretos y leyes que retratan la Educación Profesional en la segunda mitad del siglo XIX y en el transcurso del siglo XX, en Brasil y Argentina. Tomamos como punto de partida el proceso de expansión de la escuela en esos espacios, en razón de coadunarse al movimiento internacional de escolarización de las masas populares ocurrido en el siglo XIX, con vistas a la formación de mano de obra para el trabajo, en alineamiento con los ideales liberales difundidos en América Latina. Esos ideales se difunden a través de leyes que refuerzan la dualidad educacional y contribuyen al aumento de las desigualdades sociales, siendo la escuela uno de los espacios fundamentales de disputas políticas y sociales. Seleccionamos, para ese fin, fuentes documentales y bibliográficas referentes a reglamentos que tratan sobre educación profesional en Brasil y Argentina. Utilizamos ese recorte hermanado de espacio y tiempo, buscando percibir por intermédio de la metodología de la Historia Comparada las diferencias y semejanzas, pero también las singularidades, para así pensar en las influencias compartidas entre esas dos realidades. Concluyendo que, esos países se acercan en lo que respecta a sus modelos educativos orientados al trabajo y están fuertemente dirigidos por los intereses de las elites y de los organismos internacionales en el proceso de construcción de sus leyes y reformas educativas, que no siempre son sinónimos de progreso e inclusión.

Surgical management of impacted third molars is a treatment performed by dentists and its indicated for various conditions, among the indications has the prevention of mandibular fracture, but this is a factor that has been discussed and is controversial. Fractures caused by a third molar can occur, and on the other hand, the fractures after or during the management of impacted third molar are a possible complication. Surgical planning as the indication to the surgery has to be performed to avoid complications as the fracture. Thus this study aims to report a case about a mandible fracture after third molar extraction, presenting edema, pain, and restriction in mandible mobility in 01-day follow-up. A 27-year-old female was referred to the oral and maxillofacial surgery service of the Santa Casa Hospital of Araçatuba (Araçatuba, Brazil), reporting dental history of third molar removal, with immediately chief complaints. In the assessment, the patient presented edema, pain, malocclusion, and restriction in mandible mobility, and the panoramic X-ray showed a mandible fracture with displacement. The patient underwent surgery under general anesthesia to open reduction with internal fixation (ORIF) through an intraoral approach. On the follow-up, the patient showed an improvement in mouth opening and mandibular mobility without pain or infection signs. The panoramic X-Rays showed us the bone fracture healing.

Os conhecimentos de fisiologia aeroespacial são essenciais para as equipes aeromédicas realizarem a assistência aos pacientes em voo. O Conselho Federal de Enfermagem (COFEN), entendendo a importância de regulamentar a atuação da enfermagem nesse contexto de atuação, publicou em 2017 a Resolução nº 0551 que determina quais são os conhecimentos essenciais de fisilogia aeroespacial necessários para a atuação do enfermeiro de voo. Desta forma, esse estudo desenvolveu-se com o Objetivo de realizar, por meio de levantamento bibliográfico,  quais os conhecimentos de fisiologia aeroespacial são evidenciados na literatura como importantes para a atuação do enfermeiro aeroespacial. Material e Método: Estudo de revisão integrativa, de abordagem qualitativa elaborada em seis etapas: elaboração da pergunta norteadora; busca ou amostragem na literatura, coleta de dados, análise crítica dos estudos incluídos, discussão dos resultados e apresentação da revisão integrativa. Foram pesquisados artigos publicados no período de 2008 a 2021, nas bases Literatura Latino-americanos e do Caribe em Ciências da Saúde - LILAC, Scientific Electronic Library Online - Scielo e Biblioteca Virtual em Saúde - BVS. Dos artigos encontrados 07 publicações apresentavam aderência ao tema em estudo. Resultados e Discussão: Foram evidenciados alguns efeitos importantes da fisilogia aeroespacial ao corpo humano e tais efeitos interferem sobre a assistência de enfermagem em voo. Sendo eles, a hipóxia de voo, o disbarismos, a alteração abrupta da temperatura e da umidade, a aerocinetose e as acelerações. Conclusão: o enfermeiro de voo, para realizar com segurança a assistência aos pacientes aerorremovidos, necessita de sólidos conhecimentos de fisiologia aeroespacial para realizar uma assitência de enfermagem eficiente, segura e baseada na cientificidade. Observou-se ainda que, apesar de haver concenso sobre a importância desse tipo de conhecimento para as tripulações aeromédicas, pouco material literário foi encontrado nas bases indexadas.
