Dziecko i dzieciństwo: wybrane konteksty badań
Authors: MŁYNARCZUK-SOKOŁOWSKA ANNA
Published: May 2020

Dziecko jest niezwykle istotnym podmiotem edukacji o którym dużo pisano i pisze się na płaszczyźnie różnych nauk (pedagogiki, psychologii, filozofii, socjologii). Zmiana paradygmatyczna wyzwoliła nowe wizje dziecka w teoriach naukowych (Zwiernik 2015: 84–86). Zaczęto dostrzegać, że dziecko jest autonomicznym podmiotem, który może być skoncentrowany na sobie w sposób podmiotowy oraz być twórcą własnego świata i rozwoju. Dlatego też dziś coraz częściej zwraca się uwagę na fakt, iż dziecko jest zdolne do aktywnej partycypacji w życiu społecznym zarówno w grupach rówieśniczych, jak i w kręgu dorosłych (Śliwerski 2007). W takim ujęciu dzieciństwo jest poznawczą, afektywną i behawioralną rzeczywistością dziecka w której ono partycypuje i zarazem jej wytworem (Smolińska-Theiss 1993: 11–12). Dziecko w aktywny i twórczy sposób doświadcza dzieciństwa.

Authors: Cid J. Ángel
Published: May 2020

We provide new sufficient conditions for the existence ofT-periodic solutions for theϕ-laplacian pendulum equation (ϕ(x′))′ +kx′ +asinx=e(t), wheree∈C͠T. Our main tool is a continuation theorem due to Capietto, Mawhin and Zanolin and we improve or complement previous results in the literature obtained in the framework of the classical, the relativistic and the curvature pendulum equations.
A novel motion coupling coding method for brain-computer interfaces
Authors: Yan Wenqiang , Xu Guanghua
Published: May 2020

Objectives

The best frequency response band for the steady-state visual evoked potential (SSVEP) stimulus for humans is limited. This results in a reduced number of encoded targets.

Methods

To circumvent these limitations, we propose a motion-coupled, steady-state motion visual evoked potential (SSMVEP) method. We designed a stimulus paradigm that couples both sinusoidal and square wave motions. The paradigm performs a spiral motion with a higher frequency in the form of sinusoidal wave, and alters the size of the lower frequency via the square wave form.

Results

The motion-coupled SSMVEP method could simultaneously induce stable motion frequency and coupling frequency, and there was no loss of frequency component.

Conclusions

The proposed method has been evaluated to have substantial potential for increasing the number of coding targets, which is an effective supplement to the existing studies.
On birational boundedness of foliated surfaces
Authors: Hacon Christopher D. , Langer Adrian
Published: May 2020

In this paper we prove a result on the effective generation of pluri-canonical linear systems on foliated surfaces of general type. Fix a function{P:\mathbb{Z}_{\geq 0}\to\mathbb{Z}}, then there exists an integer{N>0}such that if{(X,{\mathcal{F}})}is a canonical or nef model of a foliation of general type with Hilbert polynomial{\chi(X,{\mathcal{O}}_{X}(mK_{\mathcal{F}}))=P(m)}for all{m\in\mathbb{Z}_{\geq 0}}, then{|mK_{\mathcal{F}}|}defines a birational map for all{m\geq N}.

On the way, we also prove a Grauert–Riemenschneider-type vanishing theorem for foliated surfaces with canonical singularities.
Fabrication of highly stable and durable furfurylated wood materials. Part I: process optimization
Authors: Li Wanju , Liu Minghui , Wang Hankun , Yu Yan
Published: May 2020

In order to improve dimensional stability and durability of wood, furfurylation of poplar and Chinese fir wood using newly developed furfuryl alcohol (FA) formulation combined with a common vacuum and pressure impregnation process was studied. An orthogonal experiment was designed to optimize the furfurylation process for the two wood species. The weight percent gain (WPG), equilibrium moisture content (EMC), anti-swelling efficiency (ASE), modulus of rupture (MOR), modulus of elasticity (MOE), as well as resistance to mold, decay fungi, and termites were evaluated. The results showed that nearly all the properties of the furfurylated wood could be improved to various extents. The average ASE of the furfurylated Chinese fir and poplar could reach as high as 80, 71, 92% and 79, 90, 75% in tangential and radial directions, and by volume, respectively, higher than most previously reported wood modification processes. Furthermore, the modified wood had excellent biological durability, with nearly 100% mold resistance, strong decay and termite resistance. Finally, processing parameters with 50% FA, 105–115 °C curing temperature, and 5–8 h curing time were therefore recommended for pilot-scale production of furfurylated poplar and Chinese fir wood based on range analysis.
How to manage BRCA mutation carriers?
Authors: Sabiani Laura , Barrou Julien , Mathis Jérome , Eisinger Francois , Bannier Marie , Lambaudie Eric , Houvenaeghel Gilles
Published: May 2020

Inherited mutations in BRCA1 and BRCA2 genes increase the risk of development of cancer in organs especially in breast and ovary. Prevention and screening in BRCA mutation carriers are of high importance. Prophylactic surgeries are possible but are still insufficiently performed because they require surgical procedures in healthy patients. Guidelines for the management of BRCA mutations carriers must absolutely be part of the standard practice of all those involved in the management of these patients to increase the impact of the implementation of these preventive measures. There is no screening recommended for ovarian cancer. A risk-reducing bilateral salpingo-oophorectomy should be performed from age 35 to 40 years for BRCA1 mutation carriers and 40 to 45 years for BRCA2 mutation carriers. A screening for breast cancer should be performed annually from 30 years old by breast MRI and mammography. A risk-reducing bilateral mastectomy is recommended with nipple sparing mastectomy and immediate breast reconstruction from 30 years and before 40 years. A multidisciplinary care must be implemented for these patients with an important psychological support.
Topological properties of metal-organic frameworks
Authors: Awais Hafiz Muhammad , Jamal Muhammad , Javaid Muhammad
Published: May 2020

Metal-organic frameworks (MOFs) are porous materials formed by strong bonds between metal ions and organic ligands to represent very high surface area, large pore volume, excellent chemical stability and unique morphology. Work on synthesis, structures and characteristics of many MOFs shows the importance of these frameworks with versatile applications, such as energy storage devices of excellent electrode materials, gas storage, heterogeneous catalysis, environmental hazard, assessment of chemicals and sensing of different gases. A topological property or index is a numerical invariant that predicts the physicochemical properties of the chemical compounds of the underlying molecular graph or framework. Wiener (1947) created the practice of the topological indices (TI’s) in organic molecules with the reference of boiling point of paraffin. In this paper, we study the two different metal-organic frameworks with respect to the number of increasing layers with metal and organic ligands as well. We also compute the generalized Zagreb index and generalized Zagreb connection index of these frameworks. Moreover, the various indices and connection indices are obtained by using the aforesaid generalized versions. At the end, a comparison is also included between the indices and connection indices with the help of numerical values and their 3D plots.

Published: May 2020

We report experimental observation of polarization attractors in the form of vector dissipative solitons from a carbon nanotube mode locked fiber laser. At a time scale of 14–14,000 roundtrips, the typical polarization locked vector solitons, and other appealing attractors are shown. In addition, we observe the vector dissipative solitons operated in dual-wavelength regime with central wavelength of 1533 and 1557 nm which can be related to a fixed point polarization attractor. The results unveiled complex oscillatory behavior of dissipative solitons in the polarization domain which may help understand laser physics, nonlinear optics. The demonstrated work may underpin a new type of high energy laser source leading to possible applications in nanoparticle manipulation, micromachining, spectroscopy etc.
Dynamic tuning of enhanced intrinsic circular dichroism in plasmonic stereo-metamolecule array with surface lattice resonance
Authors: Liu Shao-Ding , Liu Jun-Yan , Cao Zhaolong , Fan Jin-Li , Lei Dangyuan
Published: May 2020

Enhancing the circular dichroism signals of chiral plasmonic nanostructures is vital for realizing miniaturized functional chiroptical devices, such as ultrathin wave plates and high-performance chiral biosensors. Rationally assembling individual plasmonic metamolecules into coupled nanoclusters or periodic arrays provides an extra degree of freedom to effectively manipulate and leverage the intrinsic circular dichroism of the constituent structures. Here, we show that sophisticated manipulation over the geometric parameters of a plasmonic stereo-metamolecule array enables selective excitation of its surface lattice resonance mode either by left- or right-handed circularly polarized incidence through diffraction coupling, which can significantly amplify the differential absorption and hence the intrinsic circular dichroism. In particular, since the diffraction coupling requires no index-matching condition and its handedness can be switched by manipulating the refractive index of either the superstrate or the substrate, it is therefore possible to achieve dynamic tuning and active control of the intrinsic circular dichroism response without the need of modifying structure parameters. Our proposed system provides a versatile platform for ultrasensitive chiral plasmonics biosensing and light field manipulation.
We Make Up the Rules as We Go Along: Improvisation as an Essential Aspect of Human Practices?
Authors: Bertinetto Alessandro , Bertram Georg W.
Published: May 2020

The article presents the conceptual groundwork for an understanding of the essentially improvisational dimension of human rationality. It aims to clarify how we should think about important concepts pertinent to central aspects of human practices, namely, the concepts of improvisation, normativity, habit, and freedom. In order to understand the sense in which human practices are essentially improvisational, it is first necessary to criticize misconceptions about improvisation as lack of preparation and creatio ex nihilo. Second, it is necessary to solve the theoretical problems that derive from misunderstandings concerning the notions of normativity, habit, and freedom – misunderstandings that revolve around the idea that rationality is a form that is developed out of itself and thus works in a way similar to algorithms. One can only make sense of normativity, habit, and freedom if one understands that they all involve conflictual relationships with the world and with others, which in turn enables one to adequately take into account their constitutive connection to improvisation, properly understood. In outlining these conceptual connections, we want to prepare the foundations for an explanation of rational practices as improvisational practices. The article concludes by stating that human rational life is improvisatory because the conditions of human practice arise out of practice itself.
Growth-Dependent Activation of Protein Kinases Suggests a Mechanism for Measuring Cell Growth

Published: May 2020

In all cells, progression through the cell cycle occurs only when sufficient growth has occurred. Thus, cells must translate growth into a proportional signal that can be used to measure and transmit information about growth. Previous genetic studies in budding yeast suggested that related kinases called Gin4 and Hsl1 could function in mechanisms that measure bud growth; however, interpretation of the data was complicated by the use of gene deletions that cause complex terminal phenotypes. Here, we used the first conditional alleles of Gin4 and Hsl1 to more precisely define their functions. We show that excessive bud growth during a prolonged mitotic delay is an immediate consequence of inactivating Gin4 and Hsl1. Thus, acute loss of Gin4 and Hsl1 causes cells to behave as though they cannot detect that bud growth has occurred. We further show that Gin4 and Hsl1 undergo gradual hyperphosphorylation during bud growth that is dependent upon growth and correlated with the extent of growth. Moreover, gradual hyperphosphorylation of Gin4 during bud growth requires binding to anionic phospholipids that are delivered to the growing bud. While alternative models are possible, the data suggest that signaling lipids delivered to the growing bud generate a growth-dependent signal that could be used to measure bud growth.

Published: May 2020

Telmatobius atacamensis es un anuro microendémico amenazado de la Puna salteña. En el presente estudio se identificaron los núcleos de reproducción caracterizando sus poblaciones. Para ello se realizó un muestreo anual en los ríos Los Patos y San Antonio, estableciéndose un total de diez sitios, registrándose pH, temperatura y conductividad eléctrica en los cuerpos de agua. Se empleó la técnica de encuentro visual (TEV) para la detección de los individuos. Se establecieron tres categorías de desarrollo larval, prometamórfico (G1), premetamórfico (G2) y clímax metamórfico (G3). Se identificaron seis núcleos reproductivos, cuatro en río San Antonio y dos en río Los Patos. Los individuos se localizaron en refugios subacuáticos con un rango reducido de conductividad eléctrica y uno amplio de temperatura mientras que el pH fue alcalino. Ambos ríos mostraron diferencias en cuanto a la frecuencia relativa de categorías de estadio larval. Las abundancias de esta etapa fue significativamente diferente entre ambos (ANOVA F= 109.41 p<0.000) siendo mayor para el río Los Patos. Los individuos adultos fueron registrados en ambos ríos durante todo el ciclo, con diferencias significativas en sus abundancias (T= 19.83 p<0.0001), resultando mayor para el río Los Patos. El presente trabajo aportaría información relevante para la evaluación del estado actual de conservación y la elaboración objetiva de estrategias para el diseño de monitores efectivos, comparaciones poblacionales futuras y protección de la especie.
Selection of suitable fragment from rbcL gene for DNA barcode analysis of family Halymeniaceae, Rhodophyta
Authors: Vy Nguyen Xuan , Thu Nguyen Nhat Nhu , Hieu Nguyen Trung , Thuy Nguyen Thi Xuan
Published: May 2020

Among the members of Halymeniaceae family, Grateloupia sensu lato occupies the largest composition in species. Classification based on morphological traits is difficult due to the highly variable terete to blade-like thalli among the members of this genus that usually leads to misidentification. Molecular systematics has been applied to classify Grateloupia sensu lato so that the taxonomists acquire a better understanding of the species diversity in general. The plastid gene encoding the large subunit of ribulose-1,5-bisphosphate-carboxylase-oxygenase (rbcL) was the focus of numerous marine algal studies concerning phylogeny and molecular evolution. However, using the full length of rbcL showed disadvantages such as cost and time consuming due to two times of sequencing and two times of PCR. In the present study, the shorter sequence, fragment 773 bp at 5’ end and fragment 579 bp at 3’ end of rbcL were applied and compared for the phylogenetic analysis of Halymeniaceae members. The results indicated there are no differences of topological phylogenetic trees, species resolution within genus and genus resolution within the family between fragment 773 bp at 5’ and the full length of rbcL. Therefore, we conclude that fragment 773 bp at 5’ should be used as DNA barcodes for the Halymeniaceae to reduce the cost and time during phylogenetic analysis. Two taxa Grateloupia newly collected in Vietnam were grouped to the known Phyllymenia, a new genus in Vietnam.
Autonomy of Russian Universities: Historical Documentation Research of the 19th – 21st Century University Charters
Authors: Mazur Lyudmila , Karmanova Ekaterina
Published: May 2020

Introduction. The article compares the charters of Russian universities and brings to light the principles of universities’ operation throughout their history from the 19th to the 21st century. The article describes the model of university autonomy in Russia and its influence on the development of the academia, including contemporary universities’ ambitions in terms of global rankings.

Methods and Materials. The conceptual framework is based on the methods of documentary studies applied to analyze universities’ charters and the procedures of their development and use, including the preparation of the draft version, editing and further adjustments as well as the origin and characteristics of the document, that is, whether they resulted from ‘bottom-up’ or ‘top-down’ initiatives. The documentary analysis reveals not only the functions of charters but also the degree of universities’ autonomy as defined by these documents.

Analysis. In terms of their history and functions, three types of university charters can be identified: general (unified), standard and individual. In the Soviet and post-Soviet periods, individual charters were mostly based on standard provisions or charters, that is, they were ‘top-down’ initiatives. General and standard charters were devised by the related governmental agencies and, therefore, corresponded to the goals pursued by the government at that stage. Individual university charters resulting from ‘bottom-up’ initiatives were created in the transition periods of 1918–1922 and the 1990s, which were characterized by massive socioeconomic change and search for new models of higher education institutions.

Results. In the history of Russian higher education, there are several periods when universities had limited autonomy: early and mid-19th century (liberal reforms); 1920s (organizational and methodological experiments); 1960s (revival of limited autonomy of universities); 1990s (self-government and academic freedoms). Liberal cycles are directly reflected in the university charters, but the analysis of the procedural aspects of their development and functioning allows to conclude that autonomy should be considered as a temporary deviation from the basic model of a state university.
Between Revolt and Loyalty: Students of the Austrian Empire in the 1848 Revolution
Authors: But Julija
Published: May 2020

Introduction. As a social group with its specific features and motivation, students have been long characterized by their active involvement in social and political unrest. However, the behavioral analysis of students in different historical situations has become an independent research topic as late as in the 1960s. Numerous nuances of student activity remain for that reason unexplored. That is true of the process of student politicization and nationalization in the multi-ethnic Austrian empire during the tumultuous year of 1848. In literature, this issue is either pushed aside or based on an image of a radical “Austrian” student helping proletarians to fight against the regime on barricades. The latter is not relevant in view of the diversity of student sentiments and ideas that were present in the vast Habsburg hereditary lands.

Methods and materials. This article analyzes students’ sympathies and actual participation in the rebellious events of 1848 considering the cases of two universities – that of the capital city of Vienna and the university of provincial Innsbruck. The study is based on students’ memoires, pamphlets, letters and newspapers of that time, as well as official documents and appeals by the government.

Analysis. The analysis shows that Viennese students had an effective voice in revolutionary events, but their demands were of relatively moderate liberal character, while they largely remained loyal to the emperor. The revolutionary activity of provincial students was much more modest and peaceful than in Vienna. In case of Innsbruck, in particular, an image of a patriotic student fighting with arms for his emperor and fatherland replaced the image of a student fighting for political freedoms.

Results. The participation of students in the revolutionary events of 1848 resulted in politicization of the “Austrian” student body and its consolidation as an independent social group.
O pesadelo macabro da Covid-19 no Brasil: entre negacionismos e desvarios
Authors: Campos Gastão Wagner de Sousa
Published: May 2020

Resumo O texto discute as dificuldades para o enfrentamento do Covid-19 suscitadas pelo discurso e pelas ações defendidas por parte do governo federal. Em contraste com os governantes de países que obtiveram e00279111resultados eficazes no controle da pandemia, representantes do governo brasileiro, entre os quais se destaca o Presidente da República, vêm continuamente a público desqualificar tanto os riscos, quanto a adoção das medidas de prevenção fundamentadas cientificamente, em especial o isolamento social, defendendo, em seu lugar, a denominada ‘imunidade de rebanho’. O argumento reiterado é que existe uma oposição entre a preservação da economia e da vida, sendo prioritária a primeira. Tais manifestações vêm acompanhadas de constrangimentos para que governos estaduais e municipais possam efetivar ações de prevenção localmente definidas. Essa postura expressa o desprezo pela vida humana e uma aguda desconsideração com a população socialmente mais vulnerável, que, em países com desigualdades crônicas, como Brasil, sofrem os efeitos mais graves de uma epidemia.
Influência da propriedade familiar na estrutura e custo de capital das empresas brasileiras
Authors: Wildner Roberto , Oro Ieda Margarete , Petry David Rodrigo
Published: May 2020

Este estudo mensura a influência da propriedade na estrutura de capital das empresas familiares, comparando com as empresas não familiares, listadas na B3. As relações existentes entre estas variáveis são alvo de discussões e não há na literatura um consenso quanto à influência exercida pela gestão familiar na estrutura de capital. Para tanto, este estudo caracteriza-se como descritivo com abordagem quantitativa. Os dados foram resgatados da base de dados Economatica e a amostra consistiu de 269 empresas entre as familiares e não familiares. A revisão de literatura gerou 6 hipóteses que observaram as dimensões de propriedade, endividamento e custo de capital. Os dados foram tratados e analisados com auxílio do software SPSS, mediante estatística descritiva, correlação e regressão linear. Os resultados demonstram que o Endividamento a Longo Prazo e o Endividamento Total apresentaram coeficientes negativos, o que denota uma relação inversamente proporcional entre eles e a gestão familiar. Na regressão, os resutados apontam que as dimensões de propriedade na gestão familiar e a concentração acionária influenciam significativamente no endividamento das empresas. Denota-se uma tendência de que essa influência em empresas familiares torna-se mais significativa quando avaliada em aspectos de longo prazo. Mesmo com essa característica, empresas familiares tendem a apresentar-se menos endividadas se comparadas às demais. O controle acionário nelas não se mostrou significante nas análises propostas. E a relação entre gestão familiar, concentração acionária e controle acionário com o custo de capital não demonstrou significância, divergindo de outros estudos que evidenciaram significativas influências nessas relações. Ao final são apresentadas limitações e sugestões para novas investigações.
Gastos com vigilância epidemiológica nos municípios de Santa Catarina
Authors: Fabre Valkyrie Vieira , Engelage Emanuele , Flach Leonardo , Borgert Altair
Published: May 2020

A limitação de recursos e a priorização social têm feito com que a eficiência na saúde pública se torne pauta de diversos debates. Contudo, muitas vezes as escolhas dos governantes podem seguir prioridades individuais, conforme preconizado pela teoria das escolhas públicas, em especial na área epidêmica, que é fortemente influenciada pelo pânico e pela mídia. Diante disso, objetiva-se analisar a eficiência dos recursos públicos aplicados em vigilância epidemiológica, na mitigação de doenças como a Aids, a Dengue e a Gripe Influenza. Por meio de estatística descritiva, correlação e regressão de dados em painel, analisam-se 240 observações, em 60 municípios catarinenses, durante 4 anos. Os resultados indicam que os gastos explicam as ocorrências de Aids e de Gripe em sentido inverso ao sugerido pela literatura (quanto mais gastos, mais casos dessas doenças). Por outro lado, os casos das três doenças aumentam os gastos epidemiológicos. Portanto, as escolhas dos gestores parecem se direcionar mais para o tratamento do que para a prevenção das doenças, o que contraria os preceitos do Sistema Único de Saúde, aumenta os riscos de epidemias e pode agravar a crise na saúde pública. As discussões demonstram possíveis fatores ocasionais, como a falta de temporalidade na alimentação do sistema e distorções quanto ao local de incidência dos casos, o que também pode levar o gestor à tomada de decisão equivocada ou divergente daquela esperada por seus eleitores.

INTRODUÇÃO: A doença renal crônica (DRC) é caracterizada por alterações heterogêneas, que afetam tanto a estrutura quanto a função renal, poderá decorrer com redução da capacidade funcional e da qualidade de vida dessa população. OBJETIVO: avaliar a capacidade funcional e qualidade de vida de pacientes com DRC hospitalizados. MATERIAIS E MÉTODOS: Estudo de natureza observacional, quantitativo, descritivo, transversal. Utilizou três questionários: um clínico, o SF36 para a avaliação da qualidade de vida, e o Health Assessment Questionnaire (HAQ), para avaliação da capacidade funcional. Os dados foram analisados através de estatística descritiva, considerando média, desvio padrão e porcentagem. RESULTADOS: A amostra foi composta por 11 pacientes com DRC (63,63% homens). Os piores scores no SF36, em ambos os gêneros, foram relacionados aos aspectos físicos (0) e emocionais (0). O HAQ evidenciou maior déficit funcional no sexo feminino (1,80). Em relação à idade, em todas as faixas etárias o SF-36 apontou “aspectos físicos” (0) e “emocionais” (0) com piores índices. O HAQ encontrou pior escore na faixa de 30-59 anos e nos indivíduos com mais de três doenças associadas, Doença Renal Crônica, Hipertensão Arterial e Diabetes (deficiência moderada 1,09/1,70, respectivamente). Também foram encontrados nesses indivíduos piores scores no SF36 para os domínios de “capacidade funcional” (66,20), “estado geral” (56,50), “vitalidade” (55,00) e “aspectos sociais” (43,50). CONCLUSÃO: Os indivíduos analisados com DRC apresentaram baixos escores relacionados à qualidade de vida, e capacidade funcional moderada nas mulheres e leve nos homens.

Corruption Risks in Renewable Resource Governance: Case Studies in Iceland and Romania
Authors: Gisladottir Johanna , Sigurgeirsdottir Sigurbjörg , Stjernquist Ingrid , Ragnarsdottir Kristin Vala
Published: May 2020

In this research, we attempt to shed light on the question of where corruption risks in the governance of renewable resources are located and how they have been addressed in European countries that have different levels of corruption. A comparative case study design was chosen, looking into the fisheries sector in Iceland and the forestry sector in Romania. We conducted 25 semi-structured interviews with various stakeholders sampled through a snowball method. Qualitative coding and systems analysis were used to analyse the interviews. The results indicate that comprehensive and ambitious legislation does not necessarily translate into successful resource governance systems. In general, the institutions that were put in place to enforce and monitor the legal codes and regulations did not have the capacity to carry out their role. Additionally, interviewees were generally found to have a widespread perception of there being a corrupt relationship between politics and big companies operating in their sectors. Our findings suggest that when people hold such perceptions, it undermines anti-corruption policy efforts in the resource sectors, which can then impede sustainable resource management.

Exploring the Benefit of Yoga Programs in Carceral Settings
Authors: Rousseau Danielle , Horton Carol
Published: May 2020

This article presents a perspective on the value of yoga and mindfulness programming in carceral settings. The authors explore this topic through interviews with two formerly incarcerated people who participated in yoga programming while incarcerated and who went on to become yoga instructors themselves. Also examined are the potential effects of yoga programming for people who are incarcerated, for those working within carceral settings, and on carceral environments generally. We share recommendations for implementing yoga programming in carceral institutions and discuss policy implications. The stories of both interviewees reflect the value and potential positive effects of yoga programming within criminal justice settings and suggest the need for sustained programming and ongoing empirical evaluation.

Background: recently, it has been proved that copolymers with dextran cores and grafted polyacrylamide are effective in photodynamic and chemotherapy. However, further research is needed to define correct dosage and to assess the risks. Thus, animal studies are becoming more relevant to determine the effect of the treatment of such drug nano-systems on female reproductive function in particular.Methods: a technique for estimation of pre- and post-implantation death rates, in vitro meotic maturation of oocytes, double fluorescent vital assay and statistical analysis were used. The effects of a one-time treatment of different doses of dextran-polyacrylamide matrices and silver (Ag)-nanoparticles-dextran-polyacrylamide (AgNPs-D-PAA) on reproductive function, namely on 1) the number of oocytes isolated from one ovary and the meiotic maturation of such oocytes in vitro; 2) the indicators of cell viability of the cells of follicular environment of oocytes (FEO) and the cells of inguinal lymph nodes (ILN); 3) the pre- and post-implantation mortality rates and the number of live newborns (pups) were investigated in female mice.Results: no significant changes in the number of oocytes isolated from one ovary and meiotic maturation of such ovarian oocytes in vitro, the number of living cells of follicular environment of oocytes  and the number of such cells with morphological signs of apoptosis and necrosis, pre- and post-implantation mortality rates of embryos and the number of live newborns (pups) have been established under conditions of one-time treatment with dextran-polyacrylamide at doses of 0.39 mg/kg and 3.90 mg/kg and Ag-nanoparticles-dextran-polyacrylamide at doses of 0.20 mg/kg and 2.00 mg/kg.Conclusions: branched polymer systems (dextran-polyacrylamide (D-PAA) polymer matrices) are promising materials for use in next-generation medicine.

Published: May 2020

Background: Worldwide hypertension during pregnancy is a common cause of maternal and fetal morbidity and mortality. Effective control of blood pressure is one of the important steps in management of preeclampsia. Few drugs like nifedipine, labetalol, methyldopa, and hydralazine have acceptable high safety profile during pregnancy.Methods: In this study 120 antenatal women with non-severe preeclampsia were compared by giving either nifedipine or labetalol as a single drug therapy for control of blood pressure. Various parameters like control of blood pressure, side effects of drugs, gestational age at the time of delivery, mode of delivery, any complication and perinatal outcome were assessed.Results: In this study authors found that in both group, adequate control of blood pressure was achieved. This study shows slightly higher rate of pre term delivery and LSCS with labetalol and minimal side effects with nifedipine but difference in each group is insignificant.Conclusions: Labetalol and nifedipine both the drugs are equally effective in reducing blood pressure and any of it can safely be used as a first choice of drug for management of hypertension in preeclampsia and it can be decided as per clinician’s experience and familiarity with drug.

Background: In a well-equipped hospital, trial of vaginal delivery is done in selected cases of previous C-section (CS). Epidural analgesia administration has been proved to be good adjunct in trial of labor after caesarean (TOLAC).Methods: This study is a prospective observational study done in a tertiary care institution in Tamil Nadu from May 2019 to July 2019. 50 cases with previous history of one CS were selected. Single ton pregnancy, previous transverse lower segment cesarean section admitted cases with adequate pelvis with no other co-morbidities were selected. Epidural analgesia was administered once mother was in established labor. TOLAC was continued till satisfactory progress and emergency repeat caesarean was taken in case of Suspected scar dehiscence (SSD) or abnormal fetal heart rate tracings. Quantitative data was expressed in mean and standard deviation. For qualitative data percentage was used.Results: In 50 cases observed the mean age of the cases was 26±3.64 years. TOLAC was successful in 41 (82%) mothers out of 50. The mode of delivery in 41 TOLAC mothers was found to be forceps in 18 cases (36%) and ventouse delivery 18 cases (36%). Only 9 cases had needed emergency CS (18%). The major indication for CS in TOLAC was found to be fetal distress in 4 number of cases (8%). 43 babies delivered were healthy, 6 babies (12%) admitted in NICU.Conclusions: With the application of epidural analgesia on attempted vaginal delivery in previous cesarean, vaginal delivery was 82% cases.

Published: May 2020

Background: MTP (is common procedure done by obstetrician under certain circumstances as per MTP rules and guideline, but it has certain complication and data about complication are not fully available. The aims of this study are to analyse various complication and causes of this complication following MTP presenting at our hospital.Methods: This study was conducted in 100 patients coming to Pannadhay Rajkiya Mahila Chikitsalaya, RNT Medical college, Udaipur attending OPD (including emergency OPD) and IPD during August and September 2019 after MTP. This Study also included maternal mortality among all women participated in the study.Results: A total of 100 cases included in study attended OPD (including emergency OPD) and IPD during study period. All cases were eligible for inclusion in the study. Medical method of abortion (MMA) was the most common method of termination of pregnancy adopted by patient. Prolonged bleeding, anaemia and Incomplete abortion was the common complication related to MTP and manual vacuum aspiration was done in majority of cases to manage incomplete abortion in our hospital setting.Conclusions: The high rate of MTP related morbidity is due to induced abortion continue to be done at inappropriate places using inappropriate methods by person not eligible to do so.
Is it correct to trust each ultrasonography report blindly? a case report on misdiagnosis, diagnosis and management of acardiac twin pregnancy
Authors: Chandak Pooja , Toshniwal Shobha
Published: May 2020

Multifetal gestation is often a high-risk pregnancy and especially the monochorionic twin pregnancy significantly contributes to fetal morbidity and mortality. Acardiac twinning, earlier known as chorioangiopagus parasiticus, is the most extreme manifestation of this condition. An acardiac twin is a rare complication of multifetal pregnancy, in the literature reported at an incidence of 1% of monochorionic twin pregnancies, i.e. 1 of 35,000 pregnancies. Often results from abnormal placental vascular anastomoses. This leads to twin reversal arterial perfusion with complex pathophysiology. Here authors present a case of acardiac twin pregnancy presented at 26 weeks with the ultrasonography report suggested?? Placental teratoma of size 11×11×13 cm with polyhydramnios as there was no reason to suspect something else as the picture described in the USG report with the polyhydramnios was fitting with the diagnosis of placental teratoma but as the scan was done at taluka place and the images provided were not clear authors decided to confirm the diagnosis from fetal medicine specialist as MTP was not the option for the patient as she was 28 weeks who confirmed that as a case of acardiac twin pregnancy and the case was managed accordingly.

Background: Road traffic injuries are the leading cause of death among young people globally, especially in developing countries and burden is more among males compared to females. Human behaviors play a significant role in road traffic Injuries (RTIs), understanding road user behaviors, perception and gender differences in them is very essential to plan strategic road traffic injury prevention programs. The objectives of this study behaviors, risk perception and gender differences in young road users of a district of South India.Methods: This cross-sectional study was undertaken among 2000 young people in the age group of 18-25 years in a district of South India.Results: More than half of the youth reported unsafe behaviors as a road user. Risk behaviors such as playing on roads, using mobile while on road, high speed driving, hanging on to the doors of the bus were reported more in male gender. More than 40% perceived not following traffic safety norms as safe without significant gender differences.Conclusions: Young road users of South Indian district irrespective of gender, do not follow majority of safety norms and they perceived its safe not to follow them.

Published: May 2020

Background: Nearly 104 million (9%) of the total Indian population live in tribal areas. For the tribal population, in the recent past, many organizations initiated health programs. However, there is little understanding of the work they do in the health and nutrition area. In this scoping study, the study aimed to review NGO based models of healthcare delivery with an emphasis on reproductive, maternal health, neonatal and child health, and nutrition (RMNCHN) related interventions in tribal areas of India.Methods: A list of NGOs, in districts having 35% tribal population, was made. NGOs with functional websites, RMNCHN related interventions and registered with the Government of India online portal “NGO darpan” were selected using multistage search criteria. NGO types, their approaches for RMNCHN and intervention models were studied.Results: A total of 1503 NGOs were working on tribal health in 115 districts having >35% tribal population. Out of these, only 103 NGOs had an active health intervention and provided information freely in open public access. Only 36 NGOs had a well-structured program in reproductive, maternal, child health and nutrition area. A compendium of good practices by 12 NGOs working in RMNCHN was prepared.Conclusions: A limited number of NGOs in tribal India works on reproductive, maternal health, neonatal and child health, and nutrition issues. The health-related interventions are primarily at a small scale, community-based, lacks continuum of care and are present in districts with a lesser tribal population.
