Abstract Objective: To evaluate the imaging findings of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) and computed tomography (CT) in patients with additional primary tumors, correlating the results with those of the method used in order to elucidate the diagnosis and of the pathology reports. Materials and Methods: We retrospectively analyzed the medical records, pathology reports and images of 11 patients who underwent CT, 18F-FDG PET/CT, or both. We included patients with at least two tumors, with confirmed distinct histopathological profiles, at different sites. Patients in whom there was no diagnostic confirmation were excluded, as were those in whom the additional lesion was suspected of being a metastasis of the first. Results: New primary malignancies were identified in 11 patients, one new tumor being found in 10 and two new tumors being found in 1. The confirmed sites of the additional malignancies were the lung, kidney, prostate, jejunum, and breast. Single or multiple percutaneous biopsies were performed in 10 patients, and 1 patient underwent a surgical procedure for diagnostic and therapeutic purposes. The tumors were metachronous in 6 cases and synchronous in 5. Conclusion: CT and 18F-FDG PET-CT combined with multiple percutaneous biopsy could facilitate the diagnosis of additional lesions, thus optimizing the treatment and follow-up of the affected patients.

ABSTRACT: This paper aimed to evaluate the technological properties of particleboards produced with particles of unconventional species, bamboo of the species Phyllostachys edulis, and of the genus traditionally used by the sector for the production of the particulate panels in Brazil, Pinus spp.The bamboo splints of 3 years old were collected in Frei Rogério, Santa Catarina, being transformed into particles in a mill hammer, while the particles of Pinus spp. were collected from the industrial process of MDP production in Bonet Madeiras e Papéis Ltda Company in Santa Cecília, Santa Catarina. The company used eight-year-old logs of P. taeda and P. elliottii from the thinning process, without distinction of the species. The experiment was composed of five compositions with mixing the bamboo and wood particles in different proportions ((T1)100:0%; (T2)75:25%; (T3)50:50%; (T4)25:75%; (T5)0:100%). The panels were produced nominal density of 700 kg / m³ and pressing cycle of 160ºC and 40 kgf/cm² for 8 minutes. Results reporting physical and mechanical properties of panels were evaluated through Analysis of Variance and Tukey´s Test at 95% probability. The results evidenced that bamboo particles presented potential for the production of particleboard. The most promising results were presented with the addition of 50% of bamboo in the panel composition (T3), mainly by means observed for dimensional stability, as for strength and stiffness. Values of internal bond presented significantly lower averages with the addition of more than 25% of bamboo.

Published: June 2019

ABSTRACT: This study vised to detect possible changes in chemical and cellular composition of cow’s milk at different milking sessions and to test if proportional or composite milk sampling can be used instead of separate milk analysis. Two experiments were conducted: one in cows milked thrice daily and the other one in cows milked twice daily. In both experiments, three milk samples were collected from each cow in each milking session in order to determine milk composition at each milking; to have a composite sample, i.e., a single sample from the same aliquots of milk from each milking session; and to have a proportional sample, i.e., a single sample from each milking session in a volume proportional to milk volume yielded. Fat content and fat to protein ratio were higher in the afternoon on both experiments. Protein content was larger in the afternoon on cows milked twice daily, but not on cows milked thrice daily. Lactose level was not different across the milking sessions in any of the experiments. The urea level was higher in the afternoon and evening milking on cows milked thrice daily, and in the morning milking on cows milked twice daily. Somatic cell count did not differ between milking in any experiment. No difference in milk composition was noted between proportional and composite samples on cows milked thrice or twice daily. The collection of proportional and composite samples is recommended in twice or thrice daily milking sessions so that the analysis of milk components becomes more easy and cheap.

Published: June 2019

ABSTRACT: In recent years, Brazil has encouraged the cultivation of pecans to meet both demands of domestic and international market of nuts. New genetic varieties of pecans have been selected in recent years, but available scientific information on the occurrence of fungi and aflatoxins in the international literature is out of date. Therefore, the present study aimed to quantify and identify fungal microbiota and the presence of aflatoxins in pecan nuts cultivated in southern Brazil. Fifty-two pecan nut lots (Barton variety) were obtained from producers from 19 cities of Rio Grande do Sul State and analyzed by direct plating in Agar Dichloran Glycerol 18% (DG18) and Aspergillus Flavus and Parasiticus Agar (AFPA), following incubation at 25 °C for 7 days. Aflatoxins analyses were carried out using HPLC coupled with a mass spectrometer. Results revealed at least 10 different genera of fungi. Aspergillus, Penicillium, Fusarium, and Cladosporium were predominant. Xerophilic species of Aspergillus (A. wentii, A. ruber, A. pseudoglaucus, and A. chevalieri) were commonly reported in the samples. No potential aflatoxin-producing species was isolated and no aflatoxins were detected (LOQ=1 μg/kg and LOD=0.1 μg/kg for AFB1 and AFB2, and 0.3 μg/kg for AFG1 and AFG2) in the evaluated samples. The absence of this carcinogenic group of mycotoxins is highly positive and could boost the investments in the sector, as well as stimulate the commercialization and consumption of this variety of nut.
Azeredo Coutinho e a física do voo controlado de balões
Authors: Andrades José Carlos Corrêa de , Moutinho Adriano Martins , Pereira José Fernandes
Published: June 2019

Resumo Este artigo tem por objetivo fazer a análise de um manuscrito elaborado pelo bispo Azeredo Coutinho – fundador, em 1800, do Seminário de Olinda, em Pernambuco –, no qual se preocupa com os princípios físicos necessários para dar direção a um balão. Esse manuscrito, ofertado ao príncipe D. Pedro, foi posteriormente publicado em 1819. O problema da dirigibilidade de balões só foi efetivamente resolvido em 1901, com o voo de Santos Dumont em seu dirigível N.° 6, que lhe valeu o Prêmio Deutsch. Desde a exibição da subida aos ares de um balão de ar quente na corte de D. João V, realizada pelo padre Bartolomeu de Gusmão, em 1709, a dirigibilidade de aeróstatos – aeronaves mais leves que o ar – parecia um problema insolúvel. Para subsidiar essa análise, buscando contribuir com a história da física no Brasil, o texto explora o desenvolvimento histórico de alguns conceitos físicos que contribuíram para a aerostação, em um contexto de emergência da ciência moderna em detrimento da física aristotélica. A conclusão revela pressupostos das novas ciências naturais, compatíveis com a física de Newton, presentes no pensamento do bispo.

Published: June 2019

ABSTRACT Objective: To identify the epidemiological profile of accidents with biological material occurring in the dental clinic of a university in the southern region of the country. Methods: This is a descriptive, cross-sectional, retrospective study, which analyzed the reports of the Epidemiological Surveillance (SINAN) that occurred between March 2013 and December 2016. We analyzed the demographic variables and data related to the notification of accidents with biological material in the SINAN file, such as: age, sex, race, occupation (student, teacher, oral health technician, residents), time and place of occurrence of the accident, agent causing the perforation, total or partial use of PPE (personal protective equipment) at the time of accident, contact with organic material, contact agent and up-to-date vaccination against hepatitis B and treatment withdrawal. The data obtained were analyzed in EpiInfo Software. Statistical analysis included descriptive and inferential analysis, with significance level of p?0.05 and confidence interval (CI) of 95%. Results: In total there were 55 reports of accidents with piercing-cutting materials, of which 12 were men (21.82%) and 43 were women (78.18%). The mean age of the sample population was 24.2 (± 6.3) years. Regarding the occupation, 80% (n = 44) were undergraduate students, 12.72% were residents, 5.45%, teachers and 1.82%, oral health technicians. The majority (61.8%) were perforated during the dental procedure, 21.82% during material washing and 16.36% during surgery, but 20% claimed that they did not use any personal protective equipment. Regarding the organic material, there was a high prevalence of contact with blood, 70.9%, the needle was the main agent (n = 26; 47.3%). Still, 3.7% stated that they were not vaccinated against hepatitis B. In the bivariate analysis, the site of the accident was associated with the use of personal protective equipment (p = 0.01). Conclusion: The results showed that the number of incidents is high and can be attributed to several factors, such as lack of experience of students and the non-use of personal protective equipment. As a result, it is necessary to establish a permanent education program focused on education and accident prevention strategies to minimize these problems.

Authors: LIMA Suyanne Pimentel , SOUSA Erick Thiago de , MELO Marcílio Oliveira , SILVA Markelane Santana
Published: June 2019

ABSTRACT This article describes the application of Photodynamic Therapy as an aid to the endodontic treatment performed on a permanent tooth iatrogenically perforated and with pulp necrosis. After clinical and radiographic examination, the coronary access, curettage of the drilling area and mechanized preparation with the Reciproc System were performed. The drilling area was sealed with Mineral Trioxide Aggregate after prior alkalinization and decontamination by a calcium hydroxide buffer. After successive intracanal medication changes, the remission of the fistula, a clinical sign of endodontic infection, was not observed. Photodynamic therapy was then performed to reduce bacterial load in the root canal system, which resulted in fistula suppression. Then, it was possible to end the treatment with the obturation of the ducts by the Tagger Hybrid thermomechanical technique. After a year of proservation, the tooth presents no symptomatology and it is concluded that the Photodynamic Therapy was an effective solution in this case.

Published: June 2019

ABSTRACT Objective: This study aimed to assess the bond strength and marginal microleakage in composite resin restorations, using the Single Bond Universal adhesive system associated with Ultralux (halogen) and Bluephase (LED) light curing units. Methods: For bond strength, 80 healthy human third molars were divided into halogen light (n=40) and LED (n=40), and subdivided according to the following application techniques for the adhesive system: etch-and-rinse (enamel), self-etching (enamel), etch-and-rinse (dentin), and self-etching (dentin). The teeth were subjected to the microtensile test and the fracture pattern was observed under an optical microscope at 40X magnification; they were analyzed by ANOVA, and Fisher and Tukey’s tests (5%). For the marginal microleakage test, 120 class II cavities were prepared in 60 healthy human third molars that were randomly divided into halogen light (n=30) and LED (n=30), and subdivided according to the following application techniques for the adhesive system: etch-and-rinse, selective etching, and self-etching. The teeth were thermocycled 2000 times (±5/55°C), stained in 5% basic fuchsin and sectioned for qualitative and quantitative assessments; they were analyzed by Kruskall-Wallis and Dunn tests (5%). Results: For the bond strength of enamel and dentin, the adhesive application with prior acid etching was better than self-etching (p<0.0001), regardless of the type of light curing unit (p<0.05). Etch-and-rinse showed the lowest microleakage values (p<0.0001). Conclusion: Etch-and-rinse obtained the best results relative to the other application techniques for the adhesive system in both tests, regardless of the type of light curing unit.
Time-space characterization of droughts in the São Francisco river catchment using the Standard Precipitation Index and continuous wavelet transform
Authors: Santos Marcus Suassuna , Costa Veber Afonso Figueiredo , Fernandes Wilson dos Santos , Paes Rafael Pedrollo de
Published: June 2019

ABSTRACT This paper focuses on time-space characterization of drought conditions in the São Francisco River catchment, on the basis of wavelet analysis of Standardized Precipitation Index (SPI) time series. In order to improve SPI estimation, the procedures for regional analysis with L-moments were employed for defining statistically homogeneous regions. The continuous wavelet transform was then utilized for extracting time-frequency information from the resulting SPI time series in a multiresolution framework and for investigating possible teleconnections of these signals with those obtained from samples of the large-scale climate indexes ENSO and PDO. The use of regional frequency analysis with L-moments resulted in improvements in the estimation of SPI time series. It was observed that by aggregating regional information more reliable estimates of low frequency rainfall amounts were obtained. The wavelet analysis of climate indexes suggests that the more extreme dry periods in the study area are observed when the cold phase of both ENSO and the PDO coincides. While not constituting a strict cause effect relationship, it was clear that the more extreme droughts are consistently observed in this situation. However, further investigation is necessary for identifying particularities in rainfall patterns that are not associated to large-scale climate anomalies.

Published: June 2019

ABSTRACT: Allelopathy is defined as the ability of certain plants and microorganisms to interfere with the metabolism of other species through substances released into the environment, being an alternative to control weeds and diseases. In this context, this study aimed to evaluate the allelopathic potential and identify groups of secondary metabolites of Paspalum maritimum Trind. The species Lactuca sativa, Digitaria insularis, Emilia coccinea, and Portulaca oleracea were used as recipient plants. The ethanolic extract was obtained from shoot and root of donor species to evaluate the allelopathic potential. Potentially allelopathic effects were evaluated by means of germination tests, germination speed index, and initial seedling growth. A phytochemical analysis of the extract was also performed to identify the secondary metabolites. The ethanolic extract from both plant parts had an allelopathic effect on recipient species. The presence of condensed tannins, chalcones and aurones, flavonones, steroids, and saponins were detected in the most active fraction of the shoot of P. maritimum.

Published: June 2019

RESUMO: Este estudo investigou o nível de autoeficácia docente de futuros professores para a inclusão em aulas de Educação Física e sua relação com a fonte dos estados fisiológicos e afetivos e variáveis pessoais e contextuais. Participaram do estudo 188 estudantes de Licenciatura em Educação Física de duas universidades do interior de São Paulo. Os participantes tinham idade entre 18 e 38 anos (M = 22,6 anos) e 51,6% eram do sexo masculino. Os instrumentos de coleta de dados foram compostos por um questionário de caraterização, escala de autoeficácia para a inclusão de alunos com deficiência em aulas de Educação Física e escala de fontes de autoeficácia docente. Os dados, analisados por meio de estatística descritiva, revelaram que os participantes apresentaram níveis moderados de autoeficácia docente para inclusão em aulas de Educação Física, sendo a dimensão que obteve maior escore médio a da inclusão de alunos com deficiência física. Estados fisiológicos e afetivos relacionaram-se com maior força à inclusão de alunos com deficiência intelectual que a daqueles com deficiência física ou visual. Dada a relevância e a regularidade com que a inclusão está presente nas aulas de Educação Física, é fundamental que a formação inicial possa oferecer oportunidades para que licenciandos adquiram experiências que lhes sejam essenciais na construção, no fortalecimento e na confiança nas próprias competências, para promover a inclusão nas aulas regulares na escola.

Published: June 2019

RESUMO: O Imperial Instituto dos Meninos Cegos foi a primeira instituição escolar fundada no Brasil, no Rio de Janeiro, voltada à educação de pessoas com deficiência visual, provendo o ensino primário, musical, profissional e alguns ramos do ensino secundário. O objetivo desta pesquisa é apresentar e analisar a estrutura organizacional do Imperial Instituto dos Meninos Cegos, fundado em 1854, que utilizava o método simultâneo de ensino e esteve sob a proteção direta do Imperador até a queda da monarquia. Para tal, este trabalho consiste em uma pesquisa documental (Gil, 2002), realizada com base em fontes primárias localizadas no Arquivo Nacional, na Biblioteca Nacional, no Almanak Laemmert e em fontes bibliográficas, tais como: Aranha (2006), Araújo (1993), Jannuzzi (2004), Mazzotta (2001), Penna (2008), Veiga (2007) e Zeni (1997, 2005). O recorte geográfico e temporal da pesquisa dá-se no Rio de Janeiro, durante a segunda metade do século XIX, momento que nasceu a primeira instituição de ensino para a pessoa com deficiência visual na capital do Império. As fontes primárias analisadas constituíram-se, principalmente, por relatórios dos gestores do Instituto e dos Ministros e dos Secretários dos Negócios do Império, responsáveis pelo acompanhamento da educação. O Imperial Instituto dos Meninos Cegos instituiu as bases para a educação dos cegos no Brasil e, apesar de dar certa autonomia e proporcionar o desenvolvimento intelectual de seus alunos, fora criticada pelo seu caráter asilar, assumido por meio de suas práticas ao longo da história.

RESUMO: Este texto analisa a produção científica sobre a formação de professores no GT 15 - Educação Especial da Associação Nacional de Pós-Graduação e Pesquisa em Educação (ANPEd) no período de 2011 a 2017. Para tanto, consultou-se o resumo das comunicações e pôsteres apresentados nas páginas das edições nacionais do evento. Os dezenove estudos encontrados foram lidos e organizados em eixos: Formação inicial, Formação continuada, Formação ao longo da vida e Análise de políticas e propostas formativas. Os apontamentos iniciais indicam o crescimento da temática no GT 15, o retorno de pesquisas sobre formação inicial e a incorporação de narrativas autobiográficas. Existe uma variedade nos procedimentos adotados nos estudos - grupo focal, entrevistas, questionários e análise documental. Nas proposições, evidencia-se que: a formação nas licenciaturas tem se dado a partir de ações localizadas; há valorização dos conhecimentos produzidos coletivamente na formação continuada; existe reconhecimento dos modos que as vivências e as condições de trabalho impactam na formação; os dizeres oficiais e as propostas formativas investem em práticas de autogestão/autoinvestimento, valorizam a formação continuada em detrimento da inicial e prestigiam um saber-fazer técnico. Considera-se a necessidade de pesquisas que abordem a formação inicial do professor que atua no Atendimento Educacional Especializado, a construção de conhecimento sobre a vivência e o processo formativo nos cursos de licenciatura e trabalhos que reflitam acerca do papel da teoria na formação continuada em Educação Especial.

Published: June 2019

ABSTRACT Objective: Evaluate the performance of the Vascular Complications Risk Score in two public referral centers for interventional cardiology. Method: Subsample analysis of the Vascular Complications Risk Score, which was developed and validated in the catheterization laboratories of three cardiology referral centers (two public, one private) with a cutoff of <3 for no risk of developing vascular complications and ≥3 for risk. In this new analysis, we excluded data from the private facility, and only included participants from the original (validation) cohort of the two public hospitals. Results: Among the 629 patients studied, 11.8% had vascular complications; of these, 1.8% were major and 10% minor. Among the patients with a score <3, 310 (94.5%) presented no vascular complications; of those with a score ≥3, 50 (17%) developed complications. Of those who developed vascular complications, 18 scored <3; two of these had major complications. Conclusion: This subanalysis confirms the ability of the Vascular Complications Risk core to predict low risk of vascular complications in patients with a score < 3.

Published: June 2019

ABSTRACT Objective: To estimate the prevalence of mechanical restraint in the hospital environment and the factors associated with its performance. Method: A cross-sectional, observational study with patients from a public hospital from the medical clinic, surgical clinic and intensive care unit evaluated by descriptive, univariate and multivariate analyses. Results: One hundred eleven (111) patients participated in the study. The prevalence of mechanical restraint was 51.4%; bilateral rails on the bed were used in 100% of the restraints, and bilateral wrist restraints were also observed in 29.8%. The most common justifications were the risk of falls (100.0%) and the risk of non-scheduled removal of invasive devices (57.9%). The restrained patients differ significantly from those not restrained by the following associated factors: male gender; age; stroke diagnosis; the hospitalization unit; ambulation capacity; the use of sedative medication; and the use of invasive devices. Conclusion: This study estimated a high mechanical restraint prevalence in the hospital environment and determined factors associated with the risk of a patient being restrained. A medical restraint evaluation team is recommended for an in-depth analysis of indication and therapy.

Digital Literacy Through Digital Citizenship: Online Civic Participation and Public Opinion Evaluation of Youth Minorities in Southeast Asia
Authors: Yue Audrey , Nekmat Elmie , Beta Annisa R.
Published: June 2019

The field of critical digital literacy studies has burgeoned in recent years as a result of the increased cultural consumption of digital media as well as the turn to the production of digital media forms. This article extends extant digital literacy studies by focusing on its subfield of digital citizenship. Proposing that digital citizenship is not another dimension or axis of citizenship, but a practice through which civic activities in the various dimensions of citizenship are conducted, this article critically considers how the concept of digital citizenship can furnish further insight into the quality of online civic participation that results in claims to and acts of citizenship. Through interdisciplinary scholarship, drawing from critical media and cultural theory, and media psychology, and deriving new empirical data from qualitative digital ethnography and quantitative focus group and survey studies, it presents original case studies with young people in Southeast Asia, including young Muslim women’s groups in Indonesia and youth public opinion on LGBTs in Singapore. It argues that Southeast Asian youth digital citizenship foregrounds civic participation as emergent acts that not only serve to make society a better place, but also enacts alternative publics that characterise new modes of civic-making in more conservative, collectivistic Southeast Asian societies.
The Social Impact of Digital Youth Work: What Are We Looking For?
Authors: Pawluczuk Alicja , Webster Gemma , Smith Colin , Hall Hazel
Published: June 2019

Digital youth work is an emerging field of research and practice which seeks to investigate and support youth-centred digital literacy initiatives. Whilst digital youth work projects have become prominent in Europe in recent years, it has also become increasingly difficult to examine, capture, and understand their social impact. Currently, there is limited understanding of and research on how to measure the social impact of collaborative digital literacy youth projects. This article presents empirical research which explores the ways digital youth workers perceive and evaluate the social impact of their work. Twenty semi-structured interviews were carried out in Scotland, United Kingdom, in 2017. All data were coded in NVivo 10 and analysed using thematic data analysis (Braun & Clarke, 2006). Two problems were identified in this study: (1) limited critical engagement with the social impact evaluation process of digital youth work projects and its outcomes, and (2) lack of consistent definition of the evaluation process to measure the social impact/value of digital youth work. Results of the study are examined within a wider scholarly discourse on the evaluation of youth digital participation, digital literacy, and social impact. It is argued that to progressively work towards a deeper understanding of the social value (positive and negative) of digital youth engagement and their digital literacy needs, further research and youth worker evaluation training are required. Recommendations towards these future changes in practice are also addressed.
Critical Perspectives on Digital Literacies: Creating a Path Forward
Authors: Spires Hiller A.
Published: June 2019

This thematic issue of Media and Communication features a range of critical perspectives on digital literacies with the aim of shedding light on a path forward with respect to theory, research and practice. The issue hosts fourteen articles divided into four themes that address digital literacies in varying ways. The four themes are (a) defining digital literacies, (b) socio-cultural theories of digital literacies, (c) digital literacies in practice, and (d) digital skills and efficacy. The articles make a strong case for the continued exploration of the significance and (re)definition of digital literacies within our global communicative landscape. The authors have inspired new dialogue, research directions, innovative practices, and policy on digital literacies. As digital technologies continue to evolve so too will intellectual frameworks—generating nuance and scope for and by researchers as well as practitioners.
SOCIAL RESOURCES OF THE PRIMORSKY KRAI FOR SERVICE UNDER THE CONTRACT IN ARMED FORCES OF RUSSIA
Authors: VASHCHUK Angelina S. , CHERNOLUTSKAIA Elena N.
Published: June 2019

Introduction. The topic of military reform in Russia in the late XX - early XXI centuries is part of the fundamental problem of relations between Russian society and the army. The literature traces different approaches in her research. One of the important areas is the study of the transition to a professional army, which actualizes the problem of the social resources of such a transition, taking into account the characteristics of specific territories. The proposed article discusses the quantitative and qualitative characteristics of social resources of the Primorsky Krai for the formation of contract troops, including the demographic dynamics of the respective age cohorts, attitudes towards this type of professional activity from those who have not yet served youth (for example, students) and those who have experience contract military service.

Methods. The empirical basis of the article consists of official documents, statistical data on demographic dynamics, materials of opinion polls of 2017. The study used factor and comparative analysis; in the study of demographic resources - the method of compiling tables, longitudinal and transverse analysis. Conclusions are also obtained on the basis of the application of the questionnaire method.

Results. Over the past 10 years after the end of hostilities in Chechnya, a new social and professional group has emerged in the country - peacetime contract servicemen; elements of increased expectations of positive changes in the Russian army are actively forming in Russian society. Nevertheless, the Primorsky Krai remains a territory with a reduced social resource for recruiting young people under contract, which is important to take into account in Russia’s domestic policy. In the foreseeable 20-year term, the reduction in the number of male population suitable for contract service will continue. On the other hand, in Primorye, a low degree of orientation among students towards military service as a form of social mobility remains.

Conclusions. Despite the good implementation of recruitment plans for the Armed Forces of the Russian Federation under the contract in recent years, the degree of physical and moral readiness of young people for it was insufficient, which entailed a high “turnover” of contract soldiers in the army, the predominance of insufficiently experienced personnel among them. The policy of increasing the prestige of the social and professional status of a contractor, along with measures of material interest, must be supported by in-depth (and not just “parade”) patriotic education and preliminary moral and psychological training for young people. It is the qualitative characteristics that can increase the importance of a social recruitment resource for a contract service and, to a certain extent, compensate for the demographic restrictions in the territories.
Diagnosis and treatment of invasive Candida infections – a review article
Authors: Dąbrowska Marta , Sienkiewicz Monika , Kwiatkowski Paweł , Dąbrowski Michał
Published: June 2019

Candida albicans is the most common cause of fungal infections worldwide. Invasive candidiasis comprises candidemia and deep-seated candidiasis. Most yeast invasive infections are endogenous with a high mortality. Pathogenesis of candidiasis depends on avoiding host immune responses, as well as the virulence factors of the fungus enabling colonization and invasion of tissues. Adequate source control and antifungal therapy administered within a short time is critical to get a better prognosis. The emergence of drug resistance and the side effects of currently available antifungals are becoming the major problem in the management of Candida spp. infection.
Sosyal Bilgilerde Çevre Eğitimi: Lisansüstü Çalışmalara Ait Bir İnceleme
Authors: İBRET Bilgin Ünal , YILMAZ Onur
Published: June 2019

Çevre eğitimi, pek çok derste olduğu gibi Sosyal

Bilgiler dersinde de son derece önemli konular arasında yer almaktadır. Öyle

ki, çevre eğitiminin gerekliliği Sosyal Bilgiler Öğretim Programında da sürekli

vurgulanmaktadır. Bu bakımdan, gerek öğretmenlere gerekse bu alanda çalışan

araştırmacılara Sosyal Bilgilerde çevre eğitiminin önemini anlatmaya yönelik

büyük görevler düşmektedir. Çünkü, bir alanda yapılan akademik çalışmalar o

alanın gelişmesine katkı sağlar. Bu araştırmada, Türkiye’de Sosyal Bilgilerde

çevre eğitimine yönelik hazırlanan yüksek lisans ve doktora tezleri

incelenerek, yapılan bu lisansüstü çalışmaların yönelimleri belirlenmeye

çalışılmıştır. Araştırmada nitel araştırma yöntemlerinden doküman incelemesi

kullanılmıştır. Elde edilen veriler satır satır kodlama yapılarak

tümdengelimsel (betimsel) analiz yöntemiyle analiz edilmiş; önce temalara sonra

bu temalardan da bulgulara ulaşılmıştır. Araştırma sonucunda; Sosyal Bilgiler

alanında çevre eğitimi ile ilgili tezlerin sınırlı olduğu; Sosyal Bilgilerde

çevre eğitimi konusunun daha çok yüksek lisans düzeyinde çalışıldığı

belirlenmiştir. Ayrıca, araştırmaların genel olarak öğretmenlerden ve öğretmen

adaylarından mesleki yeterliliklerine ve çevreye karşı tutumlarına ilişkin

görüş alma şeklinde yapıldığı görülmüştür. Araştırmalar genellikle nicel

araştırma yöntemi ile yürütüldüğünden nitel araştırma yöntemine dayalı

çalışmaların çok sınırlı olduğu; daha çok ölçek ve anket uygulamaya dayalı

araştırmaların yapıldığı tespit edilmiştir. Araştırma sonuçlarına dayanarak,

çevre eğitimini konu edinen uygulamalı doktora tez çalışmalarına öncelik

verilmesi gerektiği söylenebilir. Ayrıca araştırmalarda daha derinlemesine veri

toplayabilmek amacıyla nitel araştırma yöntemlerine ağırlık verilmesi

gerekmektedir.
Reflexiones en torno al derecho a la verdad
Authors: Correal Tovar Manuel Alejandro
Published: June 2019

Las reflexiones que se ponen en consideración de la comunidad académica, están basadas en la necesidad de garantizar el derecho a la verdad en los procesos judiciales civiles, laborales y administrativos, como mecanismo para lograr el fortalecimiento y revitalización de la administración de justicia como presupuesto indispensable para la construcción de una paz estable y duradera.

 

También se examina la responsabilidad interna e internacional del Estado cuando incumple la obligación de respeto y garantía del derecho a la verdad, que cada vez cobra mayor importancia en la jurisprudencia de los Tribunales Internacionales con miras a convertirse en un derecho autónomo; empero, mientras se da el paso trascendental para el goce efectivo de los derechos humanos, se tiene que el derecho a la verdad en la mayoría de los casos se interpreta a partir de las normas consignadas en los tratados internacionales que regulan las garantías judiciales y la protección judicial.

 

Este artículo pretende identificar el estándar internacional de interpretación del derecho a la verdad y se propone examinar la línea jurisprudencial que ha trazado la Corte Interamericana de Derechos Humanos, particularmente en los casos referidos a Colombia.

La ética en la investigación
Authors: Mosquera Abadía Henry Alberto
Published: June 2019

El trabajo pone de manifiesto la falta de ética, en el desarrollo de la investigación, encontrando cómo algunos investigadores tienen la costumbre de realizar el proceso sólo por el dinero que pueden obtener, esto en ocasiones hace que se caiga en la premura o en la tentación de amañar los resultados, para complacer al financiador. También pueden ser estimulados por el deseo de prestigio, por las relaciones actuales o futuras, con lo cual hacen de la investigación una vitrina, y no un verdadero aporte a la gestión de conocimiento tanto local como nacional. Se evidenció además que una parte de los proyectos o planes de investigaciones se hacen para pedir fondos, o por lo menos se tratan cuidadosamente para tal fin. Esta práctica está muy generalizada, dicho comportamiento es perjudicial para la investigación y la sociedad, lo que hace que los problemas locales queden sin solución y lo que es peor, sin doliente. Se hicieron consultas bibliográficas relacionadas con las temáticas asociadas al estudio, así como entrevistas a colaboradores e investigadores de las Organizaciones Intensivas en Conocimiento a nivel regional. Estas técnicas proporcionan información para un análisis detallado del objeto de estudio, con el fin de establecer los factores comunes que las caracterizan, lo cual proporciona elementos para gestionar adecuadamente este tipo de organización.
Condiciones de seguridad y salud laboral identificadas en trabajadores bajo la modalidad de teletrabajo en Popayán, Cauca, Colombia*
Authors: López-Medina Ruth Esperanza , Mosquera-Angulo Hermes , Nieto-Gómez Libia Esperanza
Published: June 2019

El objetivo de esta investigación fue la identificación de condiciones de seguridad laboral y riesgo psicosocial en trabajadores bajo la modalidad de teletrabajo en la ciudad de Popayán, Cauca, Colombia. Se centró en diagnosticar el cumplimiento de la normatividad vigente: Ley 1221 de 2008 del Ministerio de Trabajo sobre el teletrabajo, y el Decreto 884 de 2012, artículo 9 que establece la Actuación de Riesgos en situaciones que llegaren a presentar los teletrabajadores. El trabajo se caracteriza por ser un estudio exploratorio. Se realiza un análisis partiendo de la caracterización de la muestra objeto, respaldada en una encuesta validada según la guía técnica para la promoción de la salud y la prevención de los riesgos laborales en el teletrabajo. La población estuvo conformada por teletrabajadores identifi- cados en Popayán de distintas entidades públicas, privadas, Network Marketing y algunos actores que ejercen la actividad de forma independiente, obteniendo como resultado índices considerables en esta población bajo algún tipo de riesgo. A nivel general se hace necesario el apoyo y la disposición de las entidades regulatorias para ejercer una política pública que conlleve al reconocimiento de esta modalidad laboral, ya que hay personas que la ejercen sin saberlo quedando expuestos a riesgos.
Responsabilidad Social Empresarial en las ladrilleras del municipio de Cartago
Authors: Duque Ceballos José Luis , García Solarte Mónica , Asprilla-Leudo An Mauricio , López-Serna Diana Marcela
Published: June 2019

En el presente artículo se hace una revisión y análisis del contexto de la Responsabilidad Social Empresarial (RSE) en el municipio de Cartago, específicamente en el sector productivo de las ladrilleras y las prácticas que éstas implementan hacia dos grupos de interés específicos: comunidad y medio ambiente. La investigación se lleva a cabo a través de un análisis cualitativo de datos e información organizacional y se complementa con trabajo de campo realizado en cinco de las ocho ladrilleras del municipio a través del diseño y aplicación de entrevistas en profundidad, con las cuales se logra concluir, entre otros elementos, que la RSE en Cartago es tema de relevancia para el sector productivo. Sin embargo, no existen lineamientos claros que permitan vincular la RSE a la estrategia de las organizaciones, por lo cual se diseñan e implementan actividades y prácticas aisladas que no se documentan o comunican con el entorno.
Derechos fiduciarios
Authors: Rolong Nieto Fernando
Published: June 2019

A diario se escucha hablar de términos como: derechos fiduciarios, encargos fiduciarios, patrimonios autónomos, fideicomisos, y otras expresiones o servicios que se presentan dentro del sector financiero; sin embargo, estos términos no siempre son bien asimilados por el escucha o por el lector pudiendo estos caer en ambigüedades o imprecisiones conceptuales o de aplicación pues en algunos casos son una figura de inversión (visto desde una óptica) y en otros constituyen una figura de financiación (como contraparte de la inversión) y en otras es un mecanismo de recaudo y posterior desembolso (cuando se contratan pagos o giros); por lo tanto, aunque el término pueda llegar a ser el mismo, su aplicación no siempre lo es, siendo entonces conveniente establecer precisiones sobre el tema. Ahora bien, en la medida en que continúen los flujos de capital extranjero, se presenten proyectos inmobiliarios, lleguen nuevas sociedades extranjeras, se expanda el mercado de capitales vía bolsa de valores, etc., conviene ambientar al lector sobre el tema fiduciario para tratar de que este tenga medianamente claro cómo funcionan estas figuras, la importancia que ellas tienen, cuáles son sus alcances, que tipo de limitantes existen y demás situaciones que le caracterizan, condicionan o limitan su actuar, sobre el entendido de que no todas las figuras serían aplicables en todas las situaciones.
