The purpose of this study was to examine the existence of subclinical left ventricular dysfunction by using 2D-STE and NT-ProBNP levels in children and adolescent patients with type 1 diabetes mellitus. Furthermore, it was also aimed to investigate the effects of the diabetes duration and the metabolic control of the disease on cardiac functions. The patient group was composed of 63 children who were being followed up for the type 1 diabetes mellitus. The control group was composed of 36 healthy children who were of the similar age. Patients with type 1 diabetes mellitus were divided into groups; according to the duration of the disease; group 1: 3-5 years, group 2: 6-10 years of follow-up. The conventional echocardiography and 2D-STE were applied to all of the patients and control individuals. NT-Pro BNP level was measured in the diabetes group. In the conventional echocardiographic examination; there was no difference between the patient and control groups in terms of left ventricular systolic functions, left ventricular diastolic functions; late-diastolic flow velocity in mitral valve (A) values increased and E-wave/A-wave ratio (E/A ) values decreased in diabetes mellitus patients. According to the 2D-STE results; global longitudinal strain, (-17.28±2.24 vs. -19.49±2.22; p < 0.05) and circumferential strain (-12.86±3.19 vs. -17.71±4.62; p < 0.05) were lower in diabetic patients compared to the parameters of control group individuals. There was no difference between levels of NT-ProBNP of the group 1 and group 2 diabetes mellitus patients. Our study showed that there was a dysfunction on the left ventricular systolic functions of the patients with type 1 diabetes mellitus. NT-Pro BNP levels were not considered as a distinguishing factor for the early stages of diabetes mellitus.

Published: July 2019

Subcutaneous allergen immunotherapy (SCIT) has been shown to improve clinical course in children with asthma and allergic rhinitis (AR). Systemic and local side-effects may be seen during its administration. The purpose of this study was to evaluate risk factors associated with systemic and local side-effects in children receiving SCIT. We performed a retrospective chart review in the children who received allergen subcutaneous immunotherapy for asthma and/or allergen rhinitis. Demographic data, diagnosis, skin prick test results, presence of additional allergic diseases, the seasonal variation of adverse events in the first and third years of SCIT were recorded. A total of 508 eligible patients were included in the study. Mean age of the children was 10.9±3.2 years, and 65.4% were male. Asthma was present in 21.9% of the children, AR in 44.7%, 33.5% of them had both asthma and AR. According to the skin prick test results, sensitivity to more than one allergen was present in 45.1%, while the most common single-allergen sensitivities were to grass pollen and dermatophagoids (32.5% and 14.4%, respectively). Ratio of systemic and local side-effects was 4.7% and 9.3%, respectively. Local side-effects were more common than systemic reaction. SCIT is a safe treatment modality while using the appropriate dose and with the administration of dose-escalation protocol.

Published: July 2019

This study aimed at investigating the lactate to albumin ratio, as a newly introduced biomarker of multiple organ dysfunction syndrome (MODS) and mortality compared to the classic lactate clearance in pediatric patients. We designed a prospective cohort study and 155 patients with severe sepsis or septic shock admitted to a Pediatric Intensive Care Unit were included, starting from January 2016 to March 2017. The data of 119 patients who completed the study, were analyzed. Results revealed that lactate clearance (6h, 24h) was significantly lower and lactate/albumin ratio (0h, 6h, 24h) was significantly higher in patients who developed MODS and in those who passed away. The univariate logistic regression showed that both lactate clearance and lactate/albumin ratio were significant prognostic factors of MODS and mortality. According to the AUC, lactate/albumin ratio (0h, 6h, 24h) showed better discrimination of MODS development (with AUC of 0.729, 0.814, and 0.819, respectively) compared to lactate clearance (6h, 24h; AUC of 0.738, and 0.672, respectively). Again the lactate/albumin ratio (0h, 6h, 24h) showed better discriminatory power of mortality (0.681, 0.741, and 0.856, respectively) compared to the lactate clearance (6h, 24h; 0.638 and 0.77, respectively). The Youden Index specified a lactate/albumin ratio (0h, 6h, 24h) of 1.17, 1.07, and 1.1 to be the cut-off discriminating values, respectively. The Kaplan-Meier curves revealed that the cumulative of survival is significantly better for the group of patients with a lactate/albumin ratio less than the cut-off values. It was concluded that lactate/albumin ratio is a better discriminator of MODS development and mortality than lactate clearance in pediatric patients with severe sepsis or septic shock.

Published: July 2019

Children spend a significant proportion of their day in school when they are not with their families.Therefore they might experience medical emergency situations due to injuries, complications of chronic health conditions, or unexpected major illnesses that occur in school. In cases of emergencies, school teachers are expected to play a key role in performing basic life support (BLS) on school children. Very limited data are present in the literature that address the knowledge of the schoolteacher regarding BLS. The primary objective of this study was to asses the BLS knowledge, training status and attitude towards pediatric BLS among schoolteachers. The study had a cross-sectional research design and was conducted between January and March 2017. A self administered questionnaire was used for data collection to assess the knowledge of teachers. The questionnaires were filled in by 541 teachers (243 male and 298 women). The median age of the study population was 39 (34-45) years. One-third of the respondents reported having taken a BLS class in the past (33.1%). The mean for the correct answers for the study population was 5/14 (4/14-7/14). For trained teachers, it was 6/14 (4/14-8/14) and for untrained teachers, it was 5/14 (3/14-7/14)(P < 0.001). There were no differences between teachers who had attended different BLS courses. Significant differences between teachers were observed: 62% of teachers with previous BLS training felt capable of providing cardio pulmonary resusitation (CPR) to their students compared to 48% in the group without previous training (P =0.001). Ninety- five percent of the teachers were eager to attend a BLS course and 92% reported that BLS training should be mandatorily given for teacher certification. Teachers are aware of the importance of BLS and they are willing to attend BLS training programs and improve their knowledge. Despite the fact that the knowledge of trained teachers was found to be better than those of untrained teachers, school teachers in Turkey have a low level of knowledge and skills regarding BLS.

Published: July 2019

This study aimed to determine prevalence and severity of malnutrition with respect to underlying diagnosis and co-morbid nutrition and feeding related problems in pediatric neurology outpatients. A total of 1,057 pediatric neurology outpatients (7.2±5.4 years, 56.9% males) were included. Data on patient demographics, neurological diagnosis, anthropometrics and Nutritional Questionnaire (NQ) for co-morbid feeding difficulties and nutritional problems were recorded. Epilepsy (45.2%) was the most common diagnosis, while prevalence of acute malnutrition was 17.7%. Nutritional support resulted in a significant decrease in the percentage of malnourished patients (from 17.1% to 6.7%, p˂0.001) and significant improvement in weight for height scores (increased to 81.42±8.17, p=0.045). In NQ-10 item assessment, at least one item was positive in 66.0% (gastrointestinal in 54.3%) of acutely malnourished patients, more commonly in severe acute malnutrition. NQ 4- item set of `red flags` revealed that prolonged meal time, meal time stressful to child or parent, lack of weight gain not just weight loss and cough during feeding were evident in 45.2%, 46.8%, 36.7% and 14.8% of patients with acute malnutrition, respectively; and more common in patients with severe malnutrition. NQ 4-item set of `red flags` was associated with high sensitivity (95%) and specificity (88%) in detection of malnutrition. In conclusion, our findings in a cohort of pediatric neurology outpatients revealed that 17.1% of overall patients were acutely malnourished along with higher prevalence of malnutrition in underlying diagnosis of cerebral palsy and higher likelihood of nutritional problems and feeding difficulties in severe malnutrition. Given the association of 6-month nutritional support with improved anthropometrics and decreased percentage of malnourished patients, our findings indicate that increased awareness of nutritional status and nutritional support is essential for the care of neurologically impaired children with potential benefit of identifying early feeding/swallowing related signs of malnutrition.

Published: July 2019

The aim of this study was to investigate the impact of general versus local anesthesia on the Posttraumatic Stress Disorder (PTSD) symptoms after circumcision. Of the 134 consecutive children (7-12 years of age) who underwent circumcision, 71 had general anesthesia (GA) and 63 had local anesthesia (LA). All participants completed the child depression inventory (CDI), State Anxiety (SA) and Trait Anxiety (TA) inventories, and Childhood Anxiety Sensitivity Index (CASI) before the operation as well as the Child Posttraumatic Stress Reaction Index (CPSRI) one month after the operation. The CDI, CASI and TA scores of the children were similar in both groups, while the SA scores of the LA group were higher than those in GA group (p < 0.001). The CPSRI scores of the GA group were higher than those of the LA group (p=0.04). When the other parameters were controlled via regression analysis, only the CDI scores and being in the GA group predicted the CPSRI scores. This study suggests that children witnessing the surgical procedure of the circumcision developed no serious symptoms of PTSD. In contrast, children exposed to GA during circumcision developed more serious PTSD symptoms than children who had LA. The severity of depressive symptoms may be important in the development of PTSD symptoms after circumcision.

Published: July 2019

Leptospirosis caused by spirochetes of the genus Leptospira in most patients result in very mild illness without jaundice. However, a small portion of patients develop various complications due to the involvement of multiple organ systems. Hemophagocytic lymphohistiocytosis is characterized by prolonged fever, hepatosplenomegaly and cytopenias, hyperferritinemia and hypertriglyceridemias, hyperfibrinogenemia, and hemophagocytosis in bone marrow, lymph nodes, spleen, or liver. Hemophagocytic lymphohistiocytosis associated with leptospirosis is a very rare condition and it should be considered in patients with multiple organ dysfunctions, together with adequate laboratory findings. It can delay the correct diagnosis of leptospirosis and contribute to an adverse outcome. We present a 13-year-old girl with secondary hemophagocytic lymphohistiocytosis caused by leptospira infection and favorable outcome with appropriate antibiotics and corticosteroid therapy.

Hematohidrosis (bloody sweat), also known as hematidrosis, is a rare clinical entity characterized by recurrent, spontaneous, self-limited episodes of blood oozing from intact skin or mucosa that are witnessed by medical personnel. We hereby report three healthy children with the history of recurrent episodes of bleeding from the intact skin over their various parts of the body. Most of these bleeding episodes occurred after stressful situations. On the basis of clinical presentation and normal investigation, they were diagnosed with hematohidrosis. We treated them with non-specific beta-blocker (propranolol). Follow-up observation of these patients demonstrated marked diminish in the frequency and severity of their episodes. In spite of the rarity of hematohidrosis, it should be considered as a differential diagnosis of bleeding episodes in patients with normal physical and laboratory investigations.

Published: July 2019

A gastric outlet obstruction (GOO) is a major complication of peptic ulcers (PUs) and corrosive ingestion in children; however, the optimal management of a patient with a GOO after a PU remains controversial. Although surgical correction is the most common treatment option, endoscopic balloon dilatation and simultaneous dilatation with a steroid injection are used more frequently as first-line treatments for PU-related GOOs. These patients require operative interventions when the obstruction cannot be managed using endoscopic approaches or in cases of relapsing after the procedure. Here, we present a case to create awareness that endoscopic balloon dilatation is a simple, effective, and safe therapy for a PU-related GOO.

Inscription, Place, and Memory: Palimpsest Rock Art and the Evolution of Highland, Andean Social Landscapes in the Formative Period (1500 – 200 BC)
Authors: Ambrosino Gordon
Published: July 2019

As more than a means of recalling, memory is an active cultural creation and landscape inscriptions construct memories by locating place-based historical narratives. To model memory in terms of engagement with a place through inscription, this study focuses on a complex palimpsest petroglyph panel at the site of Kiñan Tanka, which is situated in the highland north-central Andes. Photogrammetric modeling and vector renderings of Kiñan Tanka’s panel are analyzed to identify the microstratigraphy of its motifs. These data are paired with recently-acquired excavation data from three nearby rock art sites to reveal a tradition of incised petroglyphs that covered approximately 1300 years (1500 - 200 BC). The spatio-temporal relationships of Kiñan Tanka’s iconography are considered within its context as a venerated place and a threshold between distinct worlds during the Formative Period.

Published: July 2019

Pemeriksaan pajak sebagai wujud pengawasan dan pembinaan oleh Fiskusterhadap tingkat kepatuhan Wajib Pajak akan kewajibannya, dalam banyak hal, dapat menimbulkan "sengketa pajak", yaitu segala sesuatu yang bermuara kepada penghitungan pajak yang seharusnya dibayar oleh Wajib Pajak.Perbedaan-perbedaan yang ada pada hakikatnya memang merupakan suatu yang(hampir) lazim terjadi setelah Wajib Pajak diperiksa, karena masing-masing pihak yang bersengketa, yaitu Wajib Pajak di satu pihak dan Fiskus di pihak yang lain, merujuk kepada prinsip yang berbeda, terutama dari perbedaan prinsip yang dianut oleh akuntansi komersial dan akuntansi fiskal. Di samping itu masih ada perbedaan-perbedaan yang menyebabkan timbulnya sengketa tadi, baik yang bersifat pemahaman atas peraturan perundangan maupun perbedaan yang bersifat “non teknis”. Sarana atau upaya untuk mengatasi perbedaan-perbedaan tersebut pada tingkat yang paling awal adalah dilakukannya berbagai penyesuaian (rekonsiliasi) terhadap perbedaan prinsip yang dianut dalam sistem akuntansi, yaitu yang semula menganut prinsip akuntansi komersial dikonversi ke prinsip akuntansi fiskal. Dalam hal sengketa dimaksud menjadi berlanjut, kesempatan memperoleh hak yang dituntut oleh Wajib Pajak, masih diapresiasi oleh peraturan perundang-undangan, melalui berbagai upaya hukum yang dimulai dari hak mengajukan keberatan, upaya banding dan bahkan sampai upaya peninjauan kembali ke Mahkamah Agung. Dengan demikian harapan untuk mencapai tingkat keadilan yang hakiki bagi kedua belah pihak yang bersengketa, dapat terwujud.

Possessing language students who are skilled in creating a structured, orderly and no error-found piece of composition constitutes a hope and a wish for many EFL teachers, as they are the individuals who undergo a big problem when their students commit numerous errors in EFL writing as a result of their native language interference. This study is aimed at exploring native language influence on students� English writings as well as investigating the salient and common grammatical errors in their writing with the purpose of checking whether or not Indonesian as the students� L1 influence them when writing in English. To this end, a corpus of 22 English essays written by students is examined and the errors are then categorized according to the following aspects: grammatical, lexico-semantic, mechanics, and word order sorts of errors. In this study, mixed methods research designs are used: quantitative and qualitative. The results revealed that UNIRA students commit different sorts of errors which are chiefly on account of their native language (Indonesian) interference. The students highly rely on their L1 in stating their thoughts, even though the ranking processes revealed that their essays hold different sorts of errors, those in the grammar and the lexico-semantic statistically constitute the most serious and recurrent ones.Keywords: grammatical sentence; L1 interference; lexico-semantic; writing.

The casual conversation analyzed was a conversation of two non-native English speakers who are an English teacher and a student at a convenient situation. The conversation lasted for eighteen minutes was transcribed. Results showed that S1 dominantly used features of spontaneity on the field of repetition, incomplete utterances, and chunks. On the features of interactivity, S2 is more cooperative than S1. In addition, on the feature of interpersonally, both speakers seemed to appeal more agreement. Thus, in terms of coherence, both speakers can run the conversation smoothly. The two speakers were still making conversation in line with the topic although they changed the topic three times.
Highly Enantioselective Catalytic Allylboration of Ketiminoesters: Practical and Scalable Synthesis of α-Fully-Substituted Amino Esters
Authors: Bhakta Urmibhusan , Kattamuri Padmanabha V. , Siitonen Juha H. , Alemany Lawrence B. , Kurti Laszlo
Published: July 2019

We report the first catalytic enantioselective allylboration of α-ketiminoesters to afford chiral α-allyl-α-aryl and α-allyl-α-trifluoromethyl amino esters in excellent isolated yields and with high optical purity. This operationally simple allylation proceeds under ambient conditions with indium(I)-iodide/BOX-type ligand (5–10 mol%) and can be performed on a gram scale. A proposed qualitative model for the high stereoselectivity indicates that the origin of selectivity is likely due to attractive interactions between the substrate and the BOX ligand. Using a different BOX-type ligand reverses the reaction’s absolute sense of enantioselectivity. The allylated products are easily converted to enantiomerically enriched α-substituted proline derivatives.
Dopant Selection Strategy for High Quality Factor LSPR from Doped Metal Oxide Nanocrystals
Authors: Tandon Bharat , Ghosh Sandeep , Milliron Delia
Published: July 2019

Thin films of degenerately doped metal oxides such as those of Sn-doped In2O3 (Sn:In2O3) are commercially significant for their broad utilization as transparent conducting electrodes in optoelectronic devices. Over the last decade, nanocrystals (NCs) of Sn:In2O3 and other doped metal oxides have also attracted interest for localized surface plasmon resonance (LSPR) that occurs in the near to mid-infrared region. The suitability of this LSPR for some applications depends on its capacity to concentrate light in small regions of space, known as near-field hot spots. This efficiency to create near-field hot spots can be judged through an LSPR figure-of-merit such as Quality factor, defined as the ratio of LSPR peak energy to its linewidth. The free electron density determines the LSPR peak energy while the extent of electron scattering controls the LSPR linewidth and hence these factors together essentially dictate the value of the Quality factor. An unfortunate tradeoff arises when dopants are introduced since the aliovalent dopants generating the free electrons (increasing LSPR energy) also act as centers of scattering of electrons (increasing LSPR linewidth), thereby decreasing the LSPR Quality factor. Dopant selection is hence of paramount importance to achieve a high value of LSPR Quality factor. Here, we describe the properties of aliovalent cationic dopants that allow both high LSPR energy and low LSPR linewidth and, subsequently, high LSPR Quality factor. In this context, we identify Zr4+ as a model aliovalent dopant for high LSPR Quality factor in the In2O3 lattice. The resulting Zr-doped In2O3 NCs exhibit one of the highest LSPR Quality factors reported in the mid-infrared region while also performing equivalently to the recognized materials for either high dopant activation (Sn:In2O3 NCs) or low LSPR linewidth (Ce-doped In2O3 NCs), simultaneously. The Zr donor level is positioned well into the conduction band of In2O3 and Zr doping is surface segregated, both minimizing electron scattering. The combination of this low electron scattering and high dopant activation of Zr4+ ions is responsible for the high LSPR Quality factors. These strategies can be used to design a variety of doped metal oxide NC systems exhibiting high LSPR Quality factors.
A LITERATURA ORAL COMO FORÇA DE EXPRESSÃO DA CULTURA POPULAR:
Authors: Lummertz Frank Cardoso
Published: July 2019

Contadores de história são comuns em todo o território nacional, e a variedade de lendas, contos, fábulas e anedotas é incalculável. Essas singulares manifestações culturais aparecem por todo o mundo. Africanos, asiáticos, europeus e americanos: as pessoas do mundo todo transmitem o seu conhecimento por meio da palavra falada através do tempo. Não raro, às vezes esses conhecimentos espalhados pelos continentes se encontram e se fundem, adquirindo uma variedade de riquezas culturais ímpares. São as músicas cantadas e encenadas junto à literatura falada que constituem, em síntese, o poder da palavra no universo cultural da humanidade. Duas facetas empregam o sentido da oralidade: uma assumida pela história e outra assumida pela literatura, ora fundindo-se, ora distinguindo-se. É explicitamente específica a figura do contador, do narrador popular, aquele que unicamente se recorda das histórias fantasiosas ou não, e, nesse momento, ganha importância a partir de uma construção sociocultural. É durante a sua experiência de vida que ele, o contador, ouviu ou vivenciou as histórias para recordá-las e contá-las em uma roda de bate-papo com familiares e amigos. São os casos e são as lendas, é o real e é o imaginário, fundindo-se dentro de uma perspectiva sociocultural. O presente artigo busca intermediar significados encontrados em narrativas orais, presentes no imaginário e nas representações feitas pelo contador da história, e tenta observar elementos tidos como o real, capazes de transmitir história do tempo presente. Essa pesquisa se restringiu a vinte e dois moradores do entorno do Parque Nacional de Aparados da Serra, município de Praia Grande, Santa Catarina. Em sua integralidade destaca-se pela riqueza de detalhes históricos locais, regionais e até de aspecto nacional. Restringi o trabalho a um único exemplo adquirido nas entrevistas: a “Lenda do Gritador”, um conto local ou “causo acontecido” – como diriam alguns dos moradores – das grotas dos Aparados da Serra. Por fim, registro a importância dessas lendas, histórias e causos acontecidos, capazes de produzir sentido para diferentes grupos sociais, que num tempo passado viviam longe das redes de energia elétrica, comunicação e estradas automotivas, nesta busca que “mistura” literatura oral com uma leitura de olhar historiográfico.

Da cidade à república das letras. Jesuítas, administração vice-real, grupos letrados (México, sécs. XVI-XVII)
Authors: Reis Anderson Roberti dos
Published: July 2019

O presente artigo propõe uma reflexão sobre o papel desempenhado pelos jesuítas na formação de grupos letrados e, pois, de parcela das elites coloniais na capital da Nova Espanha. Parte-se de uma leitura clássica a respeito desse tema, aquela oferecida pelo crítico uruguaio Ángel Rama em La ciudad letrada, a fim de buscar outras possibilidades de compreensão para as relações entre os padres da Companhia de Jesus, os grupos letrados e a administração vice-real. O argumento central deste artigo sustenta que a conformação política da Monarquia Espanhola e de seus vice-reinos americanos nos séculos XVI e XVII, distante da noção de Estado Moderno e mais próxima de um modelo corporativo, torna difícil o enquadramento da atividade dos padres na perspectiva de “intelectuais a serviço da monarquia absoluta”.

O objeto do artigo é a novela alegórica História do Predestinado Peregrino e de seu irmão Precito escrita no Brasil pelo jesuíta Alexandre de Gusmão e publicada em 1682, tendo várias reedições. Gusmão ocupou na Companhia de Jesus funções importantes dentre os quais a direção de um Colégio próximo da cidade de Salvador. A hipótese proposta é a de que a novela veicula no Brasil conteúdos e métodos dos Exercícios espirituais de Inácio de Loyola. O texto segue também as orientações da Ratio Studiorum. Portanto, Gusmão teria concebido a novela como importante veículo de circulação dos exercícios inacianos. Além disto, mostra-se que a novela foi texto pioneiro escrito com o objetivo pedagógico de iniciar à leitura o público brasileiro: para esta iniciação, a novela sugere um método de leitura orientado pelos Exercícios inacianos.
Literatura religiosa nas trincheiras:
Authors: Piovezan Adriane
Published: July 2019

Levar consigo uma oração, imagem religiosa ou Bíblia era comum entre os soldados no front. Na Primeira Guerra Mundial (1914-1919) a distribuição de material religioso para os combatentes foi realizada pelos exércitos de ambos os lados do conflito. Com a Segunda Guerra Mundial (1939-1945) essa prática não foi descartada, e ao contrário, a confecção e distribuição de material religioso específico para a guerra foi aprimorada. No caso brasileiro, com o envio da FEB (Força Expedicionária Brasileira) para a Itália em 1944 para lutar ao lado dos aliados nesse conflito não foi diferente. O “Manual de Orações do Soldado Brasileiro” se insere nesse universo de material de literatura religiosa. Carregado pelos indivíduos que iriam combater como forma de apoiar sua fé essa compilação de orações abordava diversos aspectos presentes naquele contexto. Entre estes destaca-se a posição do soldado frente a iminência de sua própria morte, a questão da morte do inimigo e os procedimentos diante da morte de seus companheiros.
Definindo a ordem e a margem:

O artigo apresenta uma reflexão sobre a(s) feminilidade(s) e a(s) masculinidade(s) na Polícia Militar do Paraná, no ano de 1979, a partir de um estudo de caso. A análise de um processo de transgressão disciplinar, no qual figura como transgressores uma agente da Polícia Feminina e um Oficial da PMPR, é norteada pela categoria gênero e pelo conceito de masculinidade hegemônica. A análise indica que a relação entre a punição e a vigilância constitue as fronteiras entre a ordem e a transgressão, na Polícia Militar do Paraná, as quais são orientadas pela legislação e pela subjetividade dos agentes.
Relações de gênero e estereótipos femininos em anúncios de ontem e de hoje

Esta investigação tece reflexões questionando estereótipos femininos que evidenciam desvalorizações da mulher na mídia, e busca demonstrar que ferramentas como a propaganda não só permitem difundir discursos sexistas, mas também possibilitam abordar criticamente as relações de gênero. Para ilustrar esta discussão, foram elencados anúncios publicitários com relações intertextuais que apresentam representações de caráter generalizante e outros que combatem visões sexistas, de diferentes temporalidades e contextos. Os anúncios que ilustram o estudo têm a mulher como figura central e apelos que reiteram ou desconstroem desigualdades de gênero, denotando mudanças e permanências nas representações de ontem e de hoje. A partir dos materiais analisados, argumenta-se que os estereótipos presentes nas comunicações têm servido de modelo e parâmetro para dissolver diferentes modelos femininos, e também revelam as marcações de relações entre mulheres e homens, apontando para desafios tais como a problematização das estruturas sociais discriminatórias.
A estetização política dos lugares de memória
Authors: Bezerra Daniele Borges , Serres Juliane Conceição Primon
Published: July 2019

Neste artigo discute-se a preservação da memória em antigos leprosários, instituições criadas, nas décadas de 1930 e 1940 para isolar pessoas acometidas pelo Mal de Hansen. Com a política de profilaxia da lepra, o exercício do poder disciplinar, perpassado pela perseguição e pelo isolamento social, gerou um tipo de experiência traumática compartilhada. O sofrimento humano, de pessoas que tiveram seus direitos violados por políticas de estado, tem sido foco de atenção no campo do Patrimônio Cultural, pois as memórias incômodas, de eventos que marcaram a humanidade, dos quais Auschwitz se tornou um emblema, não podem cair no esquecimento. Chama-se atenção, contudo, para a tendência à estetização dos usos políticos da memória. É necessário observar as formas narrativas pelas quais as memórias são contadas, em lugares que se configuram como lugares de memória.
Avaliar para aprender em inglês e matemática no ensino secundário
Authors: Vieira Isabel , Santos Leonor
Published: July 2019

O presente estudo procurou compreender como duas professoras, Leonor de inglês e Ilda de matemática, implementam práticas avaliativas capazes de apoiar a aprendizagem dos seus alunos. Seguindo uma metodologia de natureza interpretativa, optámos pelo design de estudo de caso. A recolha de dados recorreu à observação de aulas e a entrevistas às professoras e a grupos focais de alunos, com registo áudio. A análise de dados seguiu a análise de conteúdo. Embora em disciplinas muito distintas, ambas as professoras apoiam os seus alunos com uma prática de avaliação formativa, assente numa abordagem positiva do erro que constitui uma fonte promissora para a atribuição de feedback.
A avaliação formativa do desempenho do ensino
Authors: Wiliam Dylan
Published: July 2019

A argumentação deste artigo se baseia em quatro propostas. Em primeiro lugar, fazem-se necessários maiores realizações educacionais tanto para os indivíduos quanto para a sociedade. Em segundo lugar, para conseguir maiores realizações educacionais se requer maior qualidade nos professores. Em terceiro lugar, uma maior qualidade nos professores demanda investir nos professores que já se encontram trabalhando em nossas escolas. Em quarto lugar, esse investimento precisa tomar um formato radicalmente distinto do desenvolvimento profissional que comumente os professores receberam.
Avaliações externas e aprendizagens dos alunos: uma reflexão crítica
Authors: Fernandes Domingos
Published: July 2019

O propósito deste texto era produzir uma reflexão crítica acerca das avaliações externas e das suas relações com as avaliações internas e com as aprendizagens dos alunos. Discutiram-se efeitos positivos e negativos das avaliações externas sobre as aprendizagens e o ensino e a necessidade de aprofundar e melhorar as avaliações internas. A reflexão produzida mostrou a possibilidade de se evoluir para outra geração de avaliações externas, baseada em princípios socialmente construídos e centrados nas aprendizagens dos alunos, devidamente articulada com outras avaliações (internas e externas) e enquadrada por políticas públicas materializadas em programas que apoiem a formação dos professores.
The Effectiveness of the Monetary Transmission Mechanism in Ukraine since the Transition to Inflation Targeting
Authors: Zholud Oleksandr , Lepushynskyi Volodymyr , Nikolaychuk Sergiy
Published: July 2019

This paper analyzes the effectiveness of monetary transmission channels in Ukraine since the National Bank of Ukraine (NBU) transitioned to inflation targeting and after the central bank established its new approach to monetary policy implementation. The authors conclude that the central bank has sufficient control over short-term interest rates in the interbank market and that it uses them to influence other financial market indicators. At the same time, further transmission via the interest rate channel is constrained by weak lending and the banking system’s slow post-crisis recovery. The exchange rate channel remains the most powerful avenue of monetary transmission. After the NBU switched to a floating exchange rate and an active interest rate policy, its key rate became a means of influencing exchange rates. The exchange rate channel’s leading role is expected to gradually decrease but remains important, as is typical for small open economies.
Estimating a Natural Level of Financial Dollarization in Ukraine
Authors: Khvedchuk Kostiantyn , Sinichenko Valentyna , Topf Barry
Published: July 2019

This article overviews the background for financial dollarization in Ukraine. We apply quantitative techniques including both minimum variance portfolio and peer comparison taking into consideration country-specific characteristics to derive an estimated natural dollarization level for Ukraine. The study also discusses potential ways for Ukraine to converge to its natural level, which we estimate at 20%. Additional factors indicate dollarization in the range of 20-30% as realistic medium-term policy goal.

Abstract- Sopo is a granary house in traditional Batak Toba architecture. Sopo is important for Batak Toba community because it serves as a place to store rice which is the source of life. Nowadays sopo is harder to find than ruma. Most of the sopo has transformed into Batak Toba house and uses as a residence. Sopo is located in Lake Toba, North Sumatra, which is prone to earthquakes. Sopo Nagari Sihotang was built in the 1920s and has experienced many earthquakes, now the sopo still survive without any structural damage. The resistance of the sopo over the years proves the sopo resilience to earthquakes. From the evidence of resilience to earthquake, its interesting to investigate the tectonics of this sopo. The purpose of the research is to understand the tectonic of Sopo Nagari Sihotang that resilience to earthquake and find local wisdom in facing earthquake disaster.The research used descriptive method with qualitative approach by describing the existing state of Sopo Nagari Sihotang and comparing it with tectonic theory and earthquake resistant structure. The sopo’s data were collected by field observation and literature study. The data are grouped into four parts, namely construction, detail, space, and ornaments that become points for analysis of tectonics. Tectonic analysis is associated with the theory of earthquake resistant structures to find out what makes tectonic of the sopo resilient to earthquakes.The result is the tectonic resilience of the Sopo Nagari Sihotang to earthquakes are found in the tectonics construction in the use of materials; tectonics detail on vertical structures and horizontal structures; and tectonics space at the story height – the activity, the spatial form – the building hape, the spatial form - the structure, and the activity - the structure. The tectonic resilience of Sopo Nagari Sihotang to earthquakes is not found in the tectonics construction and tectonics ornament. The local wisdom which are the main factors make the sopo resilience to earthquake are found on, the tectonics detail of the sopo post-batu ojahan can retain the sopo by relying on the frictional force resulting from self-weight of the sopo; the tectonics detail of the sopo post-ransang can bind every sopo posts; the use of lightweight wood materials thus reducing inertia forces. Key Words: resilience, tectonics, sopo, earthquake, Batak Toba

The Maturity of watermelons can be recognized based on watermelon skin textures. The similarity of watermelon skin texture to the background of this research was carried out. The introduction of skin texture can be extracted first-order statistical features. With the application of histogram equalization, it is expected that the statistical feature calculation process is more accurate. The use of a Gaussian filter is used to improve the image of the histogram equalization result. Support vector machine (SVM) is one method that can be used as a classification method. In this research, the statistical trait parameters used are mean, variance, skewness, kurtosis, entropy. The test was carried out using 100 images consisting of 70 training data and 30 test data. Based on the results of classification testing with SVM, 26 data were verified correctly. Accuracy results obtained were 86.66%.
