We Don't Know That We Have Been Left Behind: The Neoliberalization Of Conservation In The Burunge Wildlife Management Area, Northern Tanzania
Authors: Croucher Elizabeth
Published: March 2020

Poverty alleviation policies in Tanzania are focused on market development and local economic transformations as primary contributors to the countrys growth. These policies are intertwined with government legislation creating Wildlife Management Areas (WMAs) near protected areas which encourage local people to use village land for ecotourism activities which will add value to natural resources while providing local opportunities for expanded livelihood options. Actively promoted by international conservation NGOs, WMAs are marketed as a people-friendly way to protect wildlife while encouraging conservation-friendly livelihood strategies. This study uses qualitative ethnographic methods to determine the effects of the Burunge WMA in northern Tanzania on people living in nearby villages. Results indicate that the needs and priorities of local people were not adequately or equitably identified and that WMAs actually reregulate land and resources in a way that allows external stakeholders to gain control of village assets, exclude local people, and capitalize on newly available economic opportunities. Moreover, because WMAs merge economic and conservation objectives in a way that is consistent with both the global neoliberal framework and powerful Western images and beliefs about nature and consumption, the rhetoric regarding this newest form of community-based conservation has been transformed into an officially legislated truth that is difficult to challenge. Suggestions forcountering this discourse and for future research into the effectiveness of community-based conservation as a viable mechanism for environmental protection and economic development are offered.
The Status of Advanced Imaging Techniques for Optical Biopsy of Colonic Polyps
Authors: Glover Ben , Teare Julian , Patel Nisha
Published: March 2020

The progressive miniaturization of photonic components presents the opportunity to obtain unprecedented microscopic images of colonic polyps in real time during endoscopy. This information has the potential to act as “optical biopsy” to aid clinical decision-making, including the possibility of adopting new paradigms such as a “resect and discard” approach for low-risk lesions. The technologies discussed in this review include confocal laser endomicroscopy, optical coherence tomography, multiphoton microscopy, Raman spectroscopy, and hyperspectral imaging. These are in different stages of development and clinical readiness, but all show the potential to produce reliable in vivo discrimination of different tissue types. A structured literature search of the imaging techniques for colorectal polyps has been conducted. The significant developments in endoscopic imaging were identified for each modality, and the status of current development was discussed. Of the advanced imaging techniques discussed, confocal laser endomicroscopy is in clinical use and, under optimal conditions with an experienced operator, can provide accurate histological assessment of tissue. The remaining techniques show potential for incorporation into endoscopic equipment and practice, although further component development is needed, followed by robust prospective validation of accuracy. Optical coherence tomography illustrates tissue “texture” well and gives good assessment of mucosal thickness and layers. Multiphoton microscopy produces high-resolution images at a subcellular resolution. Raman spectroscopy and hyperspectral imaging are less developed endoscopically but provide a tissue “fingerprint” which can distinguish between tissue types. Molecular imaging may become a powerful adjunct to other techniques, with its ability to precisely label specific molecules within tissue and thereby enhance imaging.

Authors: Almeida Maria Mota , Mendes Clarisse , Fernández Carmen
Published: March 2020

Like so many secondary schools, in Portugal and elsewhere, the Sebastião e Silva Secondary School in Oeiras has important scientific collections. These mainly encompass the Natural Sciences, Physics and Chemistry fields, and their significance is associated both with the memory and identity of the School, and with local pedagogic practices, contributing therefore to the history of sciences and education in Portugal. Moreover, they reflect the value given to these subjects by their host institution, for example, by the selection of materials which integrate the collection.
The main purpose of the present essay is to explain the origins and context of the collection and its institutionalization as a museological nucleus of the School. The collection relevance and its immeasurable heritage value is a maker of a collective identity and memory of the School and the educational community. In the present paper implemented strategies of pedagogical interaction are discussed and, ultimately, problems and future perspectives are highlighted. A reflection is made about the relevance of this heritage in an era of digital technologies, as well as the main challenges in its preservation, study, interpretation and dissemination.

Published: March 2020

Mangrove forest ecosystems are  habitat of various types of microorganisms, but now, problems of mangrove forests experience are in quality and wealth. Efforts to rehabilitate activities  mangrove forests againts had been carried out but the results shown had not been maximized, so it is need the correct strategies  to achieve the success for rehabilitation activities. The studied was conducted in Teluk Kupang, East Nusa Tenggara, covered coastal areas of Kupang's mangrove forests and coastal mangrove forests in Kupang district. The method used in this studied was a systematic sampling method that was systematically distributed across all the mangrove forest areas. The method used for salinity measurement was  method of transmission and Transect Line Plots. Measurements was made in straight line and the size of the plot is 10 m x 10 m, the distanced between lines was 50 meters so that  total lane is 547 with the number of plots of observation 1641 plots. The value of  measurement results was made into the spread of salinity used the interpolation method. The condition of the crossed of  mangrove forest located on  coastal panoramas of  Kupang city shows a salinity value of 10,26 - 26.33%, while  salinity conditions was on the coast of  Kupang ten district 10-42.33 ‰. The salinity condition was formulation of the environmental conditions  mangrove forest on  coast of the island as well as attempts to support  management of mangrove forest activities. The distribution of different mangrove forest conditions along the coastal zone of North Sumatra shows an environmental condition that supports mangrove growth even though in some places the salinity values are high. Results of this study of salinity conditions is a study of the environment of mangrove growth so that it can provide an overview for the government in conducting various activities to rehabilitate mangrove forests.
Evolution of mitochondrial protein import – lessons from trypanosomes
Authors: Schneider André
Published: March 2020

The evolution of mitochondrial protein import and the systems that mediate it marks the boundary between the endosymbiotic ancestor of mitochondria and a true organelle that is under the control of the nucleus. Protein import has been studied in great detail in Saccharomyces cerevisiae. More recently, it has also been extensively investigated in the parasitic protozoan Trypanosoma brucei, making it arguably the second best studied system. A comparative analysis of the protein import complexes of yeast and trypanosomes is provided. Together with data from other systems, this allows to reconstruct the ancestral features of import complexes that were present in the last eukaryotic common ancestor (LECA) and to identify which subunits were added later in evolution. How these data can be translated into plausible scenarios is discussed, providing insights into the evolution of (i) outer membrane protein import receptors, (ii) proteins involved in biogenesis of α-helically anchored outer membrane proteins, and (iii) of the intermembrane space import and assembly system. Finally, it is shown that the unusual presequence-associated import motor of trypanosomes suggests a scenario of how the two ancestral inner membrane protein translocases present in LECA evolved into the single bifunctional one found in extant trypanosomes.
The structure of the TOM core complex in the mitochondrial outer membrane
Authors: Bausewein Thomas , Naveed Hammad , Liang Jie , Nussberger Stephan
Published: March 2020

In the past three decades, significant advances have been made in providing the biochemical background of TOM (translocase of the outer mitochondrial membrane)-mediated protein translocation into mitochondria. In the light of recent cryoelectron microscopy-derived structures of TOM isolated from Neurospora crassa and Saccharomyces cerevisiae, the interpretation of biochemical and biophysical studies of TOM-mediated protein transport into mitochondria now rests on a solid basis. In this review, we compare the subnanometer structure of N. crassa TOM core complex with that of yeast. Both structures reveal remarkably well-conserved symmetrical dimers of 10 membrane protein subunits. The structural data also validate predictions of weakly stable regions in the transmembrane β-barrel domains of the protein-conducting subunit Tom40, which signal the existence of β-strands located in interfaces of protein-protein interactions.
Modular assembly of yeast mitochondrial ATP synthase and cytochrome oxidase
Authors: Franco Leticia Veloso Ribeiro , Su Chen Hsien , Tzagoloff Alexander
Published: March 2020

The respiratory pathway of mitochondria is composed of four electron transfer complexes and the ATP synthase. In this article, we review evidence from studies of Saccharomyces cerevisiae that both ATP synthase and cytochrome oxidase (COX) are assembled from independent modules that correspond to structurally and functionally identifiable components of each complex. Biogenesis of the respiratory chain requires a coordinate and balanced expression of gene products that become partner subunits of the same complex, but are encoded in the two physically separated genomes. Current evidence indicates that synthesis of two key mitochondrial encoded subunits of ATP synthase is regulated by the F1 module. Expression of COX1 that codes for a subunit of the COX catalytic core is also regulated by a mechanism that restricts synthesis of this subunit to the availability of a nuclear-encoded translational activator. The respiratory chain must maintain a fixed stoichiometry of the component enzyme complexes during cell growth. We propose that high-molecular-weight complexes composed of Cox6, a subunit of COX, and of the Atp9 subunit of ATP synthase play a key role in establishing the ratio of the two complexes during their assembly.
Syntheticity and Recent Metaphysical Readings of Kant’sCritique of Pure Reason
Authors: Gurofsky Simon R.
Published: March 2020

Metaphysical readings of Kant’s theoretical philosophy in the Critical period are ascendant. But their possibility assumes the possibility of existence- and real-possibility-judgments about things in themselves. I argue that Kant denies the latter possibility, so metaphysical readings have dubious prospects. First, I show that Kant takes existence- and real-possibility-judgments, as necessarily synthetic, to require a relation to sensible intuition. Second, I show that the most promising metaphysical readings can ultimately neither satisfy nor explain away that requirement for existence- and real-possibility-judgments about things in themselves. I conclude with pessimistic reflections on the prospects for the metaphysical interpretive project.
Kant über das Recht des Privatgebrauchs des Erdbodens
Authors: Wolff Michael
Published: March 2020

As is well known, § 6 of Kant’s Metaphysical First Principles of the Doctrine of Right contains five paragraphs that do not belong there. The article shows that their correct location is at the end of § 16. This sheds some new light on Kant’s theory of property and its significance for Kant’s doctrine of cosmopolitan right.
The typology of sound symbolism: Defining macro-concepts via their semantic and phonetic features
Authors: Erben Johansson Niklas , Anikin Andrey , Carling Gerd , Holmer Arthur
Published: March 2020

Sound symbolism emerged as a prevalent component in the origin and development of language. However, as previous studies have either been lacking in scope or in phonetic granularity, the present study investigates the phonetic and semantic features involved from a bottom-up perspective. By analyzing the phonemes of 344 near-universal concepts in 245 language families, we establish 125 sound-meaning associations. The results also show that between 19 and 40 of the items of the Swadesh-100 list are sound symbolic, which calls into question the list’s ability to determine genetic relationships. In addition, by combining co-occurring semantic and phonetic features between the sound symbolic concepts, 20macro-conceptscan be identified, e. g. basic descriptors, deictic distinctions and kinship attributes. Furthermore, all identified macro-concepts can be grounded in four types of sound symbolism: (a) unimodal imitation (onomatopoeia); (b) cross-modal imitation (vocal gestures); (c) diagrammatic mappings based on relation (relative); or (d) situational mappings (circumstantial). These findings show that sound symbolism is rooted in the human perception of the body and its interaction with the surrounding world, and could therefore have originated as a bootstrapping mechanism, which can help us understand the bio-cultural origins of human language, the mental lexicon and language diversity.

Published: March 2020

Aim

This study aims to explain the role and mechanism of lncRNA LINC00152 in esophageal cancer.

Methods

The 30 pairs of esophageal cancer and adjacent normal tissues were collected and measuring the lncRNA LINC00152 expression by ISH and RT-qPCR assay. In the next cell experiment, Eca 109 and Kyse 150 cells were divided into 3 groups: NC group were treated with non-treatment; BL group were transfected with empty vector and lncRNA group were transfected with lncRNA LINC00152. The cells proliferation were measured by MTT assay; the cells apoptosis and cell cycle were evaluated by flow cytometry. The relative proteins expressions were measured by WB assay.

Results

Compared with NC groups, the cell proliferation rate of lncRNA groups were significantly suppressed (P<0.05, respectively); the cell apoptosis and G1 phase rates were significantly enhanced in the lncRNA groups (P<0.05, respectively). In the proteins expressions, the EGFR, PI3K and AKT proteins expressions of lncRNA group were significantly inhibited and the P21 proteins expressions were significantly stimulated in the lncRNA groups compared with those of NC groups in Eca 109 and Kyse 150 cells.

Conclusion

The lncRNA LINC00152 had anti-tumor effects on esophageal cancer in the Eca 109 and Kyse 150 cells, the mechanisms were relative with EGFR pathway.
Diversity and biogeography of picoplankton communities from the Straits of Malacca to the South China Sea
Authors: Jiang Zhao-Yu , Sun Fu-Lin
Published: March 2020

Marine picoplankton, including prokaryotic and eukaryotic picoplankton, drive many biogeochemical processes, such as carbon, nitrogen and sulfur cycles, making them crucial to the marine ecosystem. Despite the fact that picoplankton is prevalent, its diversity and spatial distribution from the Straits of Malacca (SM) to the South China Sea (SCS) remain poorly investigated. This work explores the phylogenetic diversity and community structure of picoplankton in relation to environmental factors from the SM to the SCS. To this end, the Illumina MiSeq sequencing technique was applied to 16S and 18S rRNA genes. The results showed significant differences in the dynamics of picoplankton between the open sea and the strait region. Proteobacteria and Cyanobacteria constituted a larger part of the prokaryotic group. Within Cyanobacteria, the abundance of Prochlorococcus in the open sea was significantly higher than that of Synechococcus, while the opposite trend was observed in the strait. Dinoflagellata, Cnidaria, Retaria, Tunicata, and Arthropoda dominated among the eukaryotic taxa. High-throughput sequencing data indicated that salinity, temperature and NO2-N were the key factors determining the prokaryotic community structure, while temperature and dissolved oxygen determined the eukaryotic community structure in the studied region. The network analysis demonstrated that the cooperation and competition were also important factors affecting the picoplankton community.
An algebraic model for the propagation of errors in matrix calculus
Authors: Van Tran Nam , van den Berg Imme
Published: March 2020

We assume that every element of a matrix has a small, individual error, and model it by an external number, which is the sum of a nonstandard real number and a neutrix, the latter being a convex (external) additive group. The algebraic properties of external numbers formalize common error analysis, with rules for calculation which are a sort of mellowed form of the axioms for real numbers.

We model the propagation of errors in matrix calculus by the calculus of matrices with external numbers, and study its algebraic properties. Many classical properties continue to hold, sometimes stated in terms of inclusion instead of equality. There are notable exceptions, for which we give counterexamples and investigate suitable adaptations. In particular we study addition and multiplication of matrices, determinants, near inverses, and generalized notions of linear independence and rank.
Tumor size estimation of the breast cancer molecular subtypes using imaging techniques
Authors: Sezgın Gulten , Apaydın Melda , Etıt Demet , Atahan Murat Kemal
Published: March 2020

Background and aim. In medical practice the classification of breast cancer is most commonly based on the molecular subtypes, in order to predict the disease prognosis, avoid over-treatment, and provide individualized cancer management. Tumor size is a major determiner of treatment planning, acting on the decision-making process, whether to perform breast surgery or administer neoadjuvant chemotherapy. Imaging methods play a key role in determining the tumor size in breast cancers at the time of the diagnosis.

We aimed to compare the radiologically determined tumor sizes with the corresponding pathologically determined tumor sizes of breast cancer at the time of the diagnosis, in correlation with the molecular subtypes.

Methods. Ninety-one patients with primary invasive breast cancer were evaluated. The main molecular subtypes were luminal A, luminal B, HER-2 positive, and triple-negative. The Bland–Altman plot was used for presenting the limits of agreement between the radiologically and the pathologically determined tumor sizes by the molecular subtypes.

Results. A significantly proportional underestimation was found for the luminal A subtype, especially for large tumors. The p-values for the magnetic resonance imaging, mammography, and ultrasonography were 0.020, 0.030, and <0.001, respectively. No statistically significant differences were observed among the radiologic modalities in determining the tumor size in the remaining molecular subtypes (p > 0.05).

Conclusion. The radiologically determined tumor size was significantly smaller than the pathologically determined tumor size in the luminal A subtype of breast cancers when measured with all three imaging modalities. The differences were more prominent with ultrasonography and mammography. The underestimation rate increases as the tumor gets larger.

Published: March 2020

We considera dynamical problem for semi-infinite viscothermoelastic semi infinite cylinder loaded mechanically and thermally and investigated the behaviour of variations of displacements, temperatures and stresses. The problem has been investigated with the help of five theories of the generalized viscothermoelasticity by using the Kelvin – Voigt model. Laplace transformations and Hankel transformations are applied to equations of constituent relations, equations of motion and heat conduction to obtain exact equations in transformed domain. Hankel transformed equations are inverted analytically and for the inversion of Laplace transformation we apply numerical technique to obtain field functions. In order to obtain field functions i.e. displacements, temperature and stresses numerically we apply MATLAB software tools. Numerically analyzed results for the temperature, displacements and stresses are shown graphically.
ThreThree-Dimensional Paladar Shutter Fisurated in Pediatric Patiente-Dimensional Paladar Shutter Fisurated in Pediatric Patient
Authors: Guerrero Moreno DDS Jefferson , Ubilla Mazzini DDS, Esp William
Published: March 2020

Palatal fissure is one of the congenital craniofacial malformations with the highest incidence worldwide, which compromises both the aesthetic and functional part, thus altering the vital functions: chewing, phonation, hearing and swallowing. The literature indicates that this anomaly occurs in 25% individually and 50% when associated with the cleft lip. One of the characteristics of these patients is the presence of notable malnutrition, caused by difficulty feeding, because they cannot exert enough pressure to suck breast or bottle milk; In addition, oral-nasal communication will lead to food entering the nostrils, causing regurgitation until possible bronchial aspiration. Given this problem, it is necessary to use an acrylic device capable of momentarily sealing the palatal fissure, in order to prevent the diversion of food and restore the sucking reflex in the infant. The objective of this study is to determine the effectiveness of the Three-dimensional Cleft Palate Shutter in a pediatric patient who attended the National Foundation of Maxillofacial Rehabilitation (FUNARMAF) in June 2019. The methodological design corresponds to an analytical – synthetic study since it was based on the analysis of a single case of a 5-month-old female patient, with a Unilateral Palatal Fissure (right), giving her the treatment. Results show that a closure of the oral-nasal communication was obtained, re-establishing the suction reflex. In all, it was observed that the use of this device is effective in patients with lip-palatal fissure since it acts as an adjuvant in breastfeeding and feeding the baby.

Research on gingival health of 12-year-old schoolchildren in Costa Rica is scarce. Since nutrition is an integral component of oral health, this study aimed to determine gingival status of 12-year-olds at Carmen Lyra Public School, San José, Costa Rica, and correlate these variables with the frequency of intake of different types of food and body mass index (BMI (kg/m2)). Sixty-two 12-year-old schoolchildren were recruited. A periodontist assessed Plaque Index (Silness and Löe,1964), presence of calculus, and Gingival Index (Löe and Silness, 1967). Gingivitis was defined as the presence of  bleeding on probing (BOP) on at least one site, and the extent was classified according to the percentage of teeth whose gingiva presented BOP limited: 25-49% of teeth tested; extensive >50% of teeth tested. A semi-quantified food consumption frequency questionnaire was administered. BMI was calculated for each participant. Overall Plaque Index was 1.18. Calculus was present on 40.40% of the sample, 19.4% had supragingival calculus and 21% had either supragingival/subgingival calculus or both. Presence of calculus was related with number of bleeding surfaces (p=0.030). Number of teeth with calculus was related to bleeding(p=0.029), and number of bleeding surfaces (p=0.009). Gingival Index was 0.97, mild gingivitis. Gingivitis was present on 96.8% of children examined. Limited gingivitis was present in 11.5% of children and extensive gingivitis in 88.5%. None of the variables measured differed by gender. No relationships were found between the consumption of starchy foods, animal and vegetable protein sources, fruit, vegetables, fast foods, sugar sweetened beverages and desserts with Plaque Index, calculus, Gingival Index, and BOP. Teeth calculus was related with being overweight (chi-square=0.038). BMI for males was 20.21 and females 20.11. BMI was not related to BOP or calculus. Within the limitations of this pilot study, we concluded the prevalence of gingivitis and calculus is high in the sample examined. A greater sample is needed to determine correlations between the frequency of foods evaluated and gingival health.

The traditional, Turing computation model does not have so distinct influence on knowledge creation because it is hardware-oriented. An object oriented programming language is more influential on discovery, because it works directly in the scientific domain.

The article discusses the problem of the christian concept of the human person in theological and philosophical context, and with reference to evolutionary sciences. It was pointed out that the naturalistic evolutionism undermines the most important assumptions (especially thesis proclaiming the unique status of human in nature), which is based on christian anthropology. In this paper it was also an attempt to justify that philosophical reflection can be important in the analysis of problems located between science and religion (among others the issue of the origin, nature and destiny of man). The question about new type of christian philosophy is a challenge in theology, which will be obliged – because of the changing image of the world and man – to modify its foundations, rooted mainly in the Thomistic metaphysics so far. Besides, in the context of issues relating to the meaning of human life it indicates that there is a need to develop such a philosophy, which is based on the achievements of natural science, and would be in dialogue with the contemporary humanities.

Abstract This study aimed to evaluate the factors associated with the occurrence of severe oral mucositis (SOM) in pediatric oncology patients during the chemotherapeutic treatment. This is a nested case-control to a prospective cohort that monitored 105 patients for 10 consecutive weeks after the beginning of the chemotherapy treatment. Logistic regression was used to identify the factors associated with SOM, by group of malignancy (hematologic or solid tumors) (Sig.=5%). To patients with hematologic tumors were found factors associated with SOM in two weeks of treatment: in the 6th week (increase in frequency of chemotherapy doses (OR=3.02)) and in the 7th week (female sex (OR=21.28); and increase in frequency of chemotherapy doses (OR=2.51)); and to patients with solid tumors were found factors associated with SOM in five weeks of treatment: in the 1st week (female sex (OR=14.43); age increase (OR=1.24)); in the 2nd week (Miscellany (OR=6.39)); in the 5th week (Antimetabolites (OR=17.44); Miscellany (OR=45.42); and platelets reduction (OR=1.12)); in the 6th week (creatinine increase (OR=1.63)); and in the 7th week (creatinine increase (OR=2.39)). For patients with hematologic tumors, to be female, and the increase in the frequency of chemotherapy doses increased the risk for SOM and for patients with solid tumors, to be female, the increase in age and in level blood concentration of creatinine, the reduction in number of platelets and the use of chemotherapy with miscellany and antimetabolites agents were associated with an increase in risk for occurrence of SOM.

Abstract The objective was to evaluate the color stability of ceramic veneers luted with resin cements and pre-heated composite resins (60oC) for 12 months, and determine the degree of conversion (DC) of the luting agents. Two resin cements (AllCem Veneer, light-cured (LRC) and AllCem, dual-cured (DRC)] and three composite resins [Z100 (MNCR-minifilled), Herculite Classic (MHCR-micro-hybrid) and Durafill (MCCR-microfilled)] were used for cementing 0.8-mm-thick lithium-silicate glass-ceramic laminates (Suprinity, shade B2-HT, Vita) on bovine enamel (n=10). The specimens were stored at 37oC in distilled water. CIELab parameters were determined at 24h after luting (baseline), 7, 30, 90, 180 days and 12 months. Three specimens were prepared for DC evaluation, performed by micro-Raman spectroscopy. Data were analyzed by ANOVA and Tukey’s test (a=5%). For ΔEab and ΔE00, there were significant differences for luting material (p<0.001), time (p<0.001), and double interaction (p<0.001). The groups cemented with MHCR (1 year), MCCR (90 days and 1 year) and MCCR-PH (1 year) were the ones with ΔE values greater than the acceptability threshold. All other groups maintained their ΔE lower than the acceptability threshold after 1 year in distilled water. Regarding DC, there were no significant differences (p=0.127) among the materials. Non-significant negative correlations were observed between the mean ΔEab and DC (R=-0.65) and ΔE00 and DC (R=-0.64). A significant positive correlation was observed mean ΔEab and ΔE00 (R=0.99). It was concluded that the different luting agents influenced the final color of the restorations. The heating of the composite resins did not affect their DC.

Abstract The present study was evaluated the effect of different light activation and thermocycling methods on the shear bond strength (SBS) and on the adhesive remnant index (ARI) of metal brackets bonded to feldspathic ceramic. Hundred metal brackets were bonded to 20 porcelain cylinders, divided into four groups (n=25) based on light activation and thermocycling processes. The cylinders were etched with 10% hydrofluoric acid for 60 s and coated with two layers of silane. The brackets were bonded with Transbond XT composite resin. Light activation in Groups 1 and 3 was performed during 3 s using the VALO Ortho Cordless appliance with irradiance 3,200 mW/cm2 and in Groups 2 and 4 for 40 s using Optilight Max appliance with irradiance 1,200 mW/cm². The samples were stored in deionized water at 37°C for 24 h and the samples from Groups 1 and 2 were submitted to the SBS test at a rate of 1 mm/min, whereas the samples from Groups 3 and 4 were submitted to 7,000 thermal cycles (5°/55°C) before to the SBS test. The data were assessed by two-way analysis of variance and by Tukey’s test (a=0.05). No significant difference was observed between SBS means in the different light activation devices used. The samples subjected to thermocycling revealed lower SBS values (p≤0.05). There was predominance of score 0 for ARI in all groups. Therefore, the different light activation methods did not interfere in SBS, but thermocycling reduced SBS.

Abstract The Brazilian Dental Journal (BDJ) was officially launched in 1990, stimulated by the courage and boldness of researchers dedicated to teaching and research in dentistry. The journal was conceived in a worldwide coverage and universal language to allow publication of the results of Brazilian studies, which otherwise would not be accessible to the scientific dental community. In the year we celebrate the thirtieth anniversary of BDJ, this article presents a brief overview of Brazilian dental research and a bibliometric analysis of the articles published in this journal as a contribution to our readers and fellow researchers. The purpose was to identify the mot frequent categories of study, the most published areas of dentistry and BDJ’s top 50 most-cited articles in the Scopus and Google Scholar databases. A search was performed on all BDJ online issues published from 1990 to 2019. In this period, BDJ published 1,710 articles. Based on their distribution by category of study, 557 articles were in the basic research/dental materials area, 527 in the basic research/biology area and 280 in the clinical research area. Eight articles were cited more than 100 times in the Scopus database and 266 times in the Google Scholar database. Endodontics was the most published area. This overview of BDJ production over those 30 years allows establishing a profile of the characteristics, impact and trends of the published studies, as well as the journal’s contribution to the top 50 most-cited articles in the Scopus and Google Scholar databases.
Austeridade fiscal, autoritarismo e política educacional: as mudanças legislativas na gestão democrática do sistema estadual de ensino e da escola pública de Mato Grosso
Authors: Costa Marilda de Oliveira , Domiciano Cassia
Published: March 2020

RESUMO Este texto analisa parte do mapeamento iniciado em Mato Grosso que modificou a legislação estadual relacionada à gestão democrática da escola pública. Alterações que não encontram terreno fértil em um Estado democrático de direito, mas emergem em um contexto de aprofundamento de medidas neoliberais e neoconservadoras que ganharam espaço, principalmente, a partir de 2016 com o “impeachment”, ou golpe de Estado, que retirou a presidenta eleita do executivo nacional. Após tal feito, em nome do emprego, do crescimento e da estabilidade econômica são reproduzidos e ampliados discursos que invocam a revisão constitucional (Emenda 95/2016), reformas trabalhista e previdenciária. Em Mato Grosso (MT), o governador Pedro Taques (2015-2018), do Partido da Social Democracia Brasileira (PSDB), vem desconstruindo os princípios da gestão democrática, garantidos constitucionalmente, por meio de um conjunto de medidas legislativas que os descumprem. O método adotado para análise entrecruza informações do período de 2016 a 2018, coletadas em sites oficiais do governo do estado do MT e dados documentais, confrontados com discursos e motivações dos principais atores envolvidos na alteração da política do estado, analisado à luz de referenciais teórico-críticos que abordam o tema Estado, sociedade e educação no contexto de (re)atualização neoliberal. Ao final, discute-se a relação entre a corrosão do princípio constitucional da gestão democrática nas escolas públicas do estado e o retorno mais virulento de velhas e autoritárias formas políticas no país.
Perspectivas conceptuales en salud mental y sus implicaciones en el contexto de construcción de paz en Colombia
Authors: Hernández-Holguín Dora María
Published: March 2020

Resumen Este artículo presenta una reflexión crítica sobre las perspectivas conceptuales en salud mental, en busca de nuevos sentidos para este concepto y sus implicaciones en el contexto de construcción de paz en Colombia. Para esto se realizó una revisión integrativa de la literatura, por medio de siete bases de datos bibliográficas y motores de búsqueda. Como resultado, se identificaron cinco perspectivas conceptuales de salud mental: 1) biomédica y conductual, 2) del bienestar y las potencialidades, 3) cultural, 4) psicosocial y 5) de la determinación social, cuyos fundamentos epistemológicos, sus aportes, críticas y limitaciones se describen en cada caso. Al encontrar mayor pertinencia en la propuesta de salud mental desde la salud colectiva/medicina social que desde la salud pública clásica para la construcción de paz en Colombia, se propone una mirada integral de la salud mental que tenga en cuenta su pertinencia socio-cultural desde una posición crítica y socio-histórica.

Resumo Este artigo objetiva i) descrever e analisar a expansão do provimento de dentistas no Sistema Único de Saúde (SUS); ii) identificar e analisar as características do vínculo trabalhista dos dentistas com o serviço; iii) caracterizar as vagas em concurso público, no que se refere aos requisitos, atribuições e remuneração. Neste estudo de caso, descritivo, foram consultados bancos de dados do Ministério da Saúde e editais de concurso público. Os achados apontam que 48% dos dentistas cadastrados no Cadastro Nacional dos Estabelecimentos de Saúde (CNES) realizam atendimento no SUS, em 13 anos observou-se um aumento de 118% dos municípios com equipes de saúde bucal (eSB) implantadas. A cobertura populacional estimada pelas eSB aumentou 10,46% entre os anos de 2007 e 2015. O principal mecanismo de ingresso nos Centros de Especialidades Odontológicas (CEO) foi o concurso público. O salário na atenção primária variou de 1,05 a 12,67 salários mínimos, para cargos de 40 horas semanais e nos CEOs de 3,35 a 7,05. Conclui-se que é necessário, entre outras medidas, o planejamento de estratégias voltadas aos recursos humanos em saúde. A continuidade dos êxitos alcançados demanda que medidas regulatórias dos contratos de trabalho e apoio aos gestores entrem na agenda das ações da política em saúde bucal.

Resumo O objetivo deste artigo é estimar a prevalência de acesso e uso dos serviços de Fonoaudiologia e identificar as variáveis associadas ao acesso. Estudo transversal de base populacional. A amostra foi composta de indivíduos adultos residentes em Porto Alegre/RS. Os dados foram coletados a partir de um instrumento construído com domínios de questionários de pesquisas nacionais, com um módulo sobre Fonoaudiologia. O desfecho estudado foi o acesso ao fonoaudiólogo. Regressão de Poisson com variância robusta foi utilizada para cálculo de Razões de Prevalência com intervalos de confiança de 95%. Aceitaram participar deste estudo 214 pessoas, das quais 67,3% (n = 144) eram do sexo feminino. A média de idade foi de 54,28 (±18,83) anos. Referiram necessidade de consulta fonoaudiológica 56 (26,2%) pessoas. Todos os 56 indivíduos conseguiram realizar atendimento fonoaudiológico, dos quais 69,4% (n = 39) em consultório particular e 19,6% (n = 11) em consultório conveniado ao plano de saúde. No modelo final, maior prevalência de acesso foi associada ao sexo feminino (RP = 1,09; IC95% 1,01-1,18) e possuir alguma deficiência (RP = 1,09; IC95% 1,03-1,17). O acesso ao fonoaudiólogo é mais frequente de forma privada. Observa-se que as mulheres e deficientes possuem maior prevalência de acesso ao fonoaudiólogo.
