Authors: Batubara Saiful
Published: February 2021

Dari survei antropometrik di tujuh daerah di Indonesia didapatkan bahwa usia menstruasi pertama anak Indonesia bervariasi dari usia 12,5 tahun sampai dengan usia 13,6 tahun. Pengetahuan mengenai menstruasi sangat diperlukan oleh remaja yang telah mengalami menstruasi maupun yang belum mengalami nya. Perlunya dilakukan pendidikan kesehatan mengenai menstruasi melalui media video untuk memberikan informasi kepada remaja putri guna untuk menghindari kekeliruan yang mengaitkan menstruasi dengan suatu penyakit dan kesalahpahaman dalam praktik kebersihan diri saat menstruasi. Penelitian ini dilakukan untuk mengetahui pengaruh penyuluhan menstruasi melalui media video terhadap pengetahuan siswi kelas VII di SMPN 42 Batam. Metode penelitian ini menggunakan rancangan Quasi Experiment dengan pendekatan yang digunakan adalah one grup pretest-posttest. Penelitian ini dilakukan di SMPN 42 Batam dengan jumlah sampel sebanyak 90 yang didapatkan dari hasil perhitungan rumus slovin dan dengan teknik pengambilan yang digunakan adalah acak stratifikasi. Subjek diberi kuesioner pretest dilanjutkan dengan penyuluhan melalui media video dan kemudian diberi kuesioner posttest. Analisa data dilakukan dengan menggunakan paired t test. Terdapat pengaruh penyuluhan menstruasi melalui media video terhadap pengetahuan siswi kelas VII di SMPN 42 Batam dengan nilai p value 0,00. Perbedaan tingkat pengetahuan dapat dilihat dari kenaikan nilai mean pada saat sebelum penyuluhan 56,89 dan setelah penyuluhan menjadi 73,11 terjadi peningkatan sebesar 16,22. Berdasarkan hasil penelitian dapat disimpulkan bahwa terdapat pengaruh penyuluhan menstruasi melalui media video terhadap pengetahuan siswi kelas VII di SMPN 42 Batam.

Objective This study aimed to develop a brief self-report measure of depressive and anxiety symptoms in victims of sexual violence.Methods The sample, which consisted of 215 victims and 255 healthy controls, was recruited between December 2016 and November 2018 from eight Sunflower Centers. Eligible items were selected from existing scales of depression (CES-DC and CES-D) and anxiety (SAI-C and BAI) symptoms by item-total correlation coefficients and item response theory (IRT) analysis. Internal consistency coefficients were computed and the receiver operating characteristics curve was inspected to assess the validity of the brief scale and determine optimal cutoff scores.Results The brief scales showed high internal consistency across all age groups. The optimal cutoff score of brief depression scale was 1.5 for children, 2.5 for adolescents, and 2.5 for the adults. That of brief anxiety scale was 8.5, 6.5, and 3.5, respectively.Conclusion The results underscore the need for age-appropriate screening measures of depressive and anxiety symptoms in victims of sexual violence.
Desinforme Pisa

Published: February 2021

En los últimos años se ha infiltrado en la sociedad resultados del Informe PISA, dándole usos de claro tatuaje ideológico según quien empuña veredictos. El PISA puede aparecer tan legítimo para justificar políticas de empleo agresivas contra el proletariado (cobran poco o están en desempleo por baja formación o escaso rendimiento en el Informe PISA, en comparación con trabajadores de otros países...), como puede blandirse para evadir mejoras pendientes del sistema educativo. Es decir, incitan a conformarse con leves apaños aparentes desde los resultados del alumnado obtenidos en pruebas a ciencias o lenguaje -sin mero análisis a si la lectura es comprensiva y crítica-. Este artículo profundiza en parcelas del sistema educativo igual de importantes a las que aborda el PISA, pero no tan presentes o que son desconsideradas como subalternas: profesorado, clases sociales o cultura escolar dominante.

“Senecio ucranicus” Besser (1822) versus Senecio ucranicus Hodálová (1999) and Jacobaea borysthenica (Asteraceae): a nomenclatural clarification
Authors: Mosyakin S. L.
Published: February 2021

It is demonstrated that the name “Senecio ucranicus” has never been validated by Besser (1822) because he did not accept that name; moreover, this binomial is non-existing because the word “ucranicus” was not intended as a species epithet. The unnamed species No. 1082 discussed and compared to some other taxa by Besser in his Enumeratio… is identifiable as the currently recognized species Jacobaea borysthenica(Senecio borysthenicus). Consequently, the name S. ucranicus Hodálová (1999) proposed for a Carpathian species of Senecio s. str. is legitimate, and the name S. hercynicus Herborg subsp. ucranicus should be considered a nomenclatural combination with the authorship “(Hodálová) Greuter”. Synonymy of Jacobaea grandidentata is briefly discussed and updated.

SOSIALISASI BAHAYA SAMPAH PLASTIK BAGI MASYARAKAT DALAM KOMUNIKASI LINGKUNGAN MESSY WINDISARI 1910701005
Authors: Windisari Messy
Published: February 2021

Pencemaran Lingkungan akibat sampah plastik semakin mengkhawatirkan. Masyarakat yang kurang pengetahuan dan berperilaku buruk dalam pengelolaan sampah plastik dapat menimbulkan gangguan kesehatan dan lingkungan karena derajat kesehatan masyarakat ditentukan oleh kondisi pejamu, agent (penyebab penyakit), dan lingkungan .Sampah plastik yang berbahaya dan sulit dikelola memerlukan waktu yang cukup lama untuk membuat sampah plastik benar-benar terurai. Sampah plastik yang tidak bisa terurai oleh bakteri merupakan masalah yang serius bagi pencemaran lingkungan. Dalam Undang Undang Nomor 18 Tahun 2008 Tentang Pengelolaan Sampah, bahwa pertambahan penduduk dan perubahan pola konsumsi masyarakat menimbulkan bertambahnya volume, jenis, dan karakteristik sampah yang semakin beragam kini perlu perubahan cara pandang masyarakat mengenai sampah dan cara memperlakukan atau mengelola sampah.

Work-to-family conflict, family-to-work conflict and their relation to perceived parenting and parent-child relationship before and during the Covid-19 lockdown
Authors: Verweij Renske , Helmerhorst Katrien , Keizer Renske
Published: February 2021

Objective: Our objective is twofold: First, to examine whether, to what extent and for whom (by sex and educational attainment) work-to-family conflict (W→F-conflict) and family-to-work conflict (F→W-conflict) increased from the pre-Covid-19 period to the lockdown period. Second, to examine whether, to what extent and for whom the associations between W→F-conflict/F→W-conflict and perceived parenting (positive encouragement, coercive parenting and parent-child relationship) became stronger.Background: During the Covid-19 lockdown, parents were asked to provide childcare and home-schooling for their children while also being expected to fulfil their work obligations. Under these circumstances, this study was set out to examine how W→F-conflict/F→W-conflict, perceived parenting and their association were affected.Method: Multilevel regression models were applied to longitudinal data collected among 59 employed mothers and 77 employed fathers with a 3-year-old child.Results: We found that F→W-conflict/W→F-conflict increased most strongly among highly educated mothers, followed by lower/medium educated mothers and highly educated fathers, while no increase or even a decrease was observed among lower/medium educated fathers. We found some associations between W→F-conflict/F→W-conflict with perceived parenting, but these were not consistent for fathers nor mothers, nor across waves. Although overall heightened levels of conflict did strongly not spill-over to mothers’ and fathers’ perceived parenting, our results showed that for some parents, in particular those with high working hours, conflict clearly increased with negative implications for their perceived parenting.Conclusion: With some noteworthy exceptions, increases in F→W-conflict/W→F-conflict did not coincide with decreases in perceived parenting, indicating that most parents did not let increased conflict between work and family affect their parenting.

Multi-talented Microbots
Authors: Jain Aryan
Published: February 2021

The microbot/xenobot designs focused on in this paper have applications both inside and outside the body. What you need to know about xenobots, since they are a very new invention, is that they are layered heart and skin tissue robots built from frog stem cells. The observed tasks that have been pub- lished are organizing microplastics, self-healing, and chemical communication with pheromones. There has never been an invention similar to xenobots, which is why they are paving a revolution as the first “Living Robots”[1]. These ap- plications include micro-sculpting nerve tissue inside the body and virus detec- tion/monitoring outside the body.Inside the body, microbots and xenobots working together can represent an effective new treatment against peripheral and diabetic neuropathy, preventing paralysis. Bolstering the body’s response to neural damage by clearing the restrictions of natural neural growth would allow neurons to regrow and connect much faster[2]; xenobots[1] alone can be injected into the traumatized area to decompose myelin sheath if this process is accessible within a few hours of serious nerve damage. In the long-term, after several months/years, xenobots and microbots[3] will come together, carrying neural stem cells, and following an external electromagnetic field to regenerate neurons and micro-sculpt nerve tissue in a three-step process. First, the xenobots (with biogenic magnetite) carry the cargo of neural progenitors, dropping them off at the dorsal root ganglion (also infected with biogenic magnetite). Then, axons of the neurons growing from the neural progenitor would grow in the direction of the microbot pulling it. The infrared light would power the twisted graphene bilayer and direct the microbot, pulling neurons to invoke growth and reconnecting the network of neurons near muscles.[5]Outside the body, xenobots will monitor virus concentrations with a virus stimulus and fluorescent light indication. After the coronavirus pandemic, virus destruction products such as the MAP-1 spray for coronavirus (distributed by Germagic) have proven successful. Determining exactly when a virus has resided in a particular area has not been proven, but would greatly aid in contact trac- ing. Microbots[3] and xenobots[1] are essential for determining how long a particular virus has resided on a surface, giving information about when peo- ple could have been infected. Horizontal gene integration from synthetic RNA and DNA origami mechanisms give xenobots sensitivity to viruses. Xenobots coming in contact with viruses can indicate surface virus contact by gradually increasing/decreasing the green color that they illuminate as the Green Fluo- rescent Protein goes through a positive feedback loop as viruses increase and decrease in contact with the xenobot. [8] This half-life of fluorescence is modeled by a differential equation in Attenuation of green fluorescent protein half-life in mammalian cells.[4]

Dakwah dalam perspektif ilmu dakwah kontemporer
Authors: adawiyah Robiatul adawiyah
Published: February 2021

AbstractKeberadaan dakwah kontemporer perlu didekatkan dengan sains, terutama dalam menghadapi masalah-masalah kontemporer dewasa ini. Islam sebagai agama rahmatan lil ‘alamin harus mampu memberikan kontribusi dan sekaligus solusi terhadap perkembangan dan Perubahan masyarakat modern. Selama ini peradaban Islam, mengalami stagnan bahkan Islam terkesan menjauh dari hiruk-pikuk dunia sains. Kalau kita menengok ke belakang, justru Islam sebagai pelopor terhadap temuan-temuan sains yang kemudian dikembangkan oleh peradaban Barat. Ilmu pengetahuan dan peradaban dunia sekarang ini, kiblatnya berada pada peradaban Barat dan seakan-akan peradaban Islam mengalami stagnan tanpa ada kemajuan yang signifikan untuk kemaslahatan umat. Kemunduran sains dalam Islam dipicu oleh pemasungan pemikiran umat Islam dengan ditutupnya pintu ijtihad ditambah lagi wacana epistemologi keilmuan Islam klasik yang berpola Ghazalian (mazhab Al-Ghazali) yang belakangan lebih dominan. Tidak heran kalau prestasi temuan di bidang iptek kalah jauh dari orang Barat, bahkan dalam dunia muslim temuan sains hampir dikatakan tidak ada. Agar dakwah Islam kembali concern dengan visi sains seperti pada awal-awal peradaban keilmuan Islam, ada beberapa tawaran epistemologi dan metode dakwah melalui keilmuan muslim kontemporer, yang saat ini perlu dicoba dengan melakukan pelacakan kembali untuk melakukan integrasi sains dan agama dengan menggunakan pisau empat paradigma yang ditawarkan oleh Ian Barbour yaitu: tipologi konflik, independensi, dialog, dan integrasi. Selain itu perlu adanya redefenisi atau rekonseptualisasi terhadap wacana integrasi sains dan agama dalam keilmuan dakwah Islam.Kata kunci: IlmuDakwah Kontemporer;

Agent, Behaviour, Trace, Repeat: Understanding the Cognitive Processes Involved in Human Stigmergic Coordination
Authors: Topf Sabine , Speekenbrink Maarten
Published: February 2021

Stigmergy refers to the coordination of agents via artifacts of behaviours (behavioural traces) in the shared environment. Whilst primarily studied in biology and computer science/robotics, stigmergy underlies many human indirect interactions, both offline (e.g., trail building) and online (e.g., development of open-source software). In this review, we provide an introduction to stigmergy and emphasise how and where human stigmergy is distinct from animal or robot stigmergy, such as intentional communication via traces and causal inferences from the traces to the causing behaviour. Cognitive processes discussed on the agent level include attention, motivation, meaning and meta-cognition, as well as emergence/immergence, iterative learning and exploration/exploitation at the interface of individual agent and multi-agent systems. Characteristics of one-agent, two-agent and multi-agent systems are discussed and areas for future research highlighted.
Major Project Risk Management: Reconciling Complexity during Delivery with the Inside View in Planning
Authors: Chapman Paul , Quang Cuong
Published: February 2021

Recent research on the origins of risk during the planning and delivery of major projects broadly addresses two root causes: (i) complexity at the planning phase and also during project delivery, and; (ii) ‘the inside view’ at the planning phase and the associated issues of strategic misrepresentation and cognitive biases such as optimism bias. This paper presents the results of a systematic review that finds a schism in the literature showing theoretical and empirical treatment of project delivery risk polarises into considering either the effect of complexity or the inside view; rarely are they considered jointly. This work discusses the implications for theory and practice and identifies Case Based Decision Theory and Bayesian modelling, both of which are outside view techniques, as having potential to reconcile complexity and the inside view and thus provide for their joint treatment.
COVID-19 pandemic’s impact on online sex advertising and sex trafficking
Authors: Coxn Julia , Castro Vanessa , Carr Bridgette , Bredin Glen , Guikema Seth
Published: February 2021

Disruptive social events like the Covid-19 pandemic can have significant impact on the commercial sex industry, yet these effects have been little understood. This paper examines the effect of the pandemic on one part of the commercial sex industry: sex trafficking. Our results from scraped sexual service advertisements show that the pandemic has had measurable impact on online advertising for sex trafficking in the United States, with a significant decrease associated with stay-at-home orders followed by an increase to levels well above prepandemic levels as Covid-related restrictions were relaxed. We contribute to the policy landscape by showing that the initial decrease was associated with a loss of demand for sexual services due to pandemic-related health concerns, but that a confluence of factors, including the lack of economic and social support, increased the number of people vulnerable to being exploited. This study can assist policy makers in predicting future changes in the sex industry to support a more just and inclusive society. In the context of future health crises, natural disasters, and major social disruptions it can guide policy makers in apportioning public aid in a way that does not leave vulnerable populations and existing sex workers powerless to being trafficked.
Development Education – Globales Lernen – Global Citizenship Education. Bleibende Aporien und strategische Offerten im Weltkollektiv
Authors: Lang-Wojtasik Gregor , Schönborn Selina
Published: February 2021

The current transformation challenges of the world span between communication offers of the world society and action-related options of the world community. The inseparable unity of their difference is marked by the construct of the global collective. This serves as the point of departure for questions concerning the future potential that is intended and expectable through education and learning and that is immanent to conceptions of globally oriented educational work. Thus, the type of framework moves into focus in which the concepts of development education, global learning and global citizenship education can flourish.
Children’s Agency as a Theoretical Problem and a Practical Concern (an Anthropological Remark)
Authors: Kozlovskaya Angelina , Kozlova Anna
Published: February 2021

The introduction opens the proceedings for the conference on childhood studies “‘Through Children’s Eyes’: The Child’s Subjectivity in Social Studies and in the Public Sphere” (December 21–22, 2018, EUSPb, St Petersburg). The paper traces the history of the New Social Studies of Childhood, a research paradigm which has put forward the notion of children as competent social actors and has made claims for its universality as a conceptual framework for studying children. A close examination of the discipline formation shows that—in an attempt to draw attention to the worthiness of childhood as a research subject—proponents of the new paradigm have used politically informed arguments and have drawn on the “adult” model of rational subjects for the conceptualization of children’s practices. These, in turn, have led to the loss of specificity in the accounts of childhood experiences. Several theoretical efforts made both within and outside the “new sociology of childhood” to overcome the conceptual crisis are considered. The present collection consists of four ethnographic studies related to the issue of children’s agency. Two of these examine the soviet pedagogical disputes on the meaning of children’s independency (which in many ways are congruent to the theoretical discussion of children’s agency) and the two others explore the different forms and formats agency takes in natural settings within peer interaction.

Authors: Syamsul Tri Damayanty , Natzir Rosdiana , Hardjo Marhaen , Kasim Hasyim , Bahar Burhanuddin , Jafriati Dr. , Wahyuni Dr.
Published: February 2021

Introduction Diabetes Mellitus (DM) is a multicultural metabolic disease characterized by hyperglycemia due to abnormalities in insulin secretion, insulin action, or both. Abnormalities in insulin secretion or action cause problems in the metabolism of carbohydrates, fats, and proteins. DM Type II is characterized by the occurrence of insulin resistance in body tissues. Trigona honey is rich in phenolic compounds because it is food collected by bees from plants. The total phenolic content in honey is highly correlated with antioxidant activity. In this study, we aimed to see the different effects of trigona honey (Tetragonula sp) on plasma insulin and blood glucose levels in mice with diabetes mellitus. Methods. Balb/c mice (n= 28) were randomly assigned into the control group (n=7), negative control, positive control, and intervention group which received a daily intake of trigona honey (n= 14). Results. showed that administration of trigona honey can increase administration of the metformin. This is caused because honey contains high antioxidants and contains bioactive compounds such as alkaloids, flavonoids, triterpenoids, and phenol compounds. Conclusion. Daily consumption of trigona honey has a remarkable potential to decrease the blood glucose, thus it can contribute to the prevention of the diabetes mellitus development.
Phytochemical Screening of Plant Extracts and GC-MS Analysis of n-Hexane Extract of the Leaves of Cassia alata Linn
Authors: Saha Koushik , Proma Rezwana Zaman , Khan Nasima
Published: February 2021

The purpose of this investigation was to undergo the preliminary phytochemical screening of the plant extracts and identify the presence of pharmacologically bioactive constituents in the leaves of Cassia alata by using gas chromatography-mass spectrometry (GC-MS) technique. The preliminary phytochemical screening of different leaf extracts of Cassia alata revealed the presence of various phytochemical compounds such as terpenoids, steroids, flavonoids, phenolic compounds, quinones, carbohydrates, tannins and alkaloids. Qualitative and quantitative determination of different biologically active compounds from the crude n-hexane extract using gas chromatography-mass spectrometry disclosed 20 compounds with varying amounts where main components were identified as palmitic acid (26.65%), stearic acid (14.27%), (E)-9-octadecadienoic acid (11.40%), erucylamide (8.34%), 1,19-eicosadiene (5.15%), stigmasterol (4.68%), linoleic acid (4.06%), vitamin E (3.97%), methyl palmitate (3.93%) and methyl 11-octadecenoate (3.32%). The compounds identified through this investigation may be responsible for any of the pharmacological properties of Cassia alata and could be of considerable interests for the development of new drug leads.

Published: February 2021

The effect of ethanol leaf extract of Jatropha tanjorensis on hepatorenal function of Plasmodium berghiberghi infected mice treated with root bark extract of Hippocratea africana was evaluated. Twenty-One (21) male mice weighing between 27 – 33 g used for the study were divided into seven groups. Group 1 served as normal control while Groups 2 – 7 were parasitized with Plasmodium berghi-berghi and Group 2 was the test control group (parasitized without treatment). Group 3 was administered 8 mg/kg bw of artemether-lumefantrine for 3 days. Group 4 and 5 received daily, 200 mg/kg bw and 300 mg/kg bw of Hippocratea africana and Jatropha tanjorensis respectively for 4 days. Group 6 received 8mg/kg bw of artemether-lumefantrine for 3 days followed with 300 mg/kg bw of Jatropha tanjorensis for 4 days. Group 7 was treated with 200 mg/kg bw of Hippocratea africana for 4 days followed by 300 mg/kg bw of Jatropha tanjorensis for 4 days. The concentration of urea, creatinine and the activities of the liver enzymes were observed to increase significantly following induction of malaria when compared to normal control. Treatment with artemether-lumefantrine and root bark extract of Hippocratea africana showed drug induced hepatorenal toxicity which was ameliorated with the administration of ethanol leaf extract of Jatropha tanjorensis. The study showed that Jatropha tanjorensis leaf extract had hepatorenal protective function against Plasmodium berghi-berghi infection and malaria treatment induced toxicity, that may be due to its rich phytochemicals with antioxidant activity.
Quantum Molecular Polyhedra and Atomic Populations
Authors: Carbó-Dorca Ramon
Published: February 2021

The present paper uses the LCAO MO theory formalism. The structure of the first order electronic density function is decomposed in two kinds of quantum polyhedra to discuss the behavior of quantum atomic populations. Among the many aspects one can consider about atomic populations here, the quantum mechanical structure of the density function is taken as the most important characteristic to think about. Apart of the usual one-electron basis set, centered in the molecular atoms, there is also discussed the possibility that the three-dimensional space where the molecular structures are described can be also the site of basis functions centered in points non-coincident with atomic positions.

Signatures, as one of the behavioral human characteristics are generally recognized as legal means for verifying an individual's identity by administrative and financial institutions. A signature is developed by a person and it can change over time. Signatures are prone to influences by age, physical and mental conditions. In this study tremulous signatures including questioned and standards related to 50 real cases resolved by National Forensic Science Laboratory of Nepal were collected. The time interval between questioned and standard signatures was up to ten years. Sixteen major characteristics along with their forty-one sub characteristics of each case were studied. Among sixteen major characteristics in the tremulous signatures, study shows that the characteristics like the style of writing in hand printed form, pen pauses, medium pen pressure, poor line quality, pen lifts are most prominently observed. Tremors were absent mostly in the terminal strokes of letters. The letters written were varied in size and those were 6% small, 70% medium and 24% large. Interestingly no any retouch attempts were found to complete the shape of letters.
Extracción de polifenoles y composición de vinos tintos Tannat elaborados por técnicas de maceración prefermentativa
Authors: Piccardo Diego , González-Neves Gustavo
Published: February 2021

Con el objetivo de evaluar el efecto de la técnica de maceración sobre la extracción de compuestos fenólicos y la composición del vino al descube, durante la vendimia 2011 se elaboraron vinos tintos Tannat por maceración prefermentativa en frío (MF: mosto sometido cinco días a una temperatura entre 5 y 10 °C con una maceración fermentativa posterior de ocho días), prefermentativa en caliente (MC: mosto sometido seis horas a temperatura entre 60-65 ºC previo a una maceración fermentativa de ocho) y tradicional (MT: mosto sometido a una maceración con fermentación de ocho días). Se comparó la extracción de polifenoles totales y de antocianos obtenida con cada técnica de vinificación, realizando análisis diarios de estos compuestos desde el encubado hasta el descube, en donde se determinó además la intensidad colorante, tonalidad y porcentajes de amarillo, rojo y azul para cada técnica empleada. La extracción de polifenoles totales y antocianos en los mostos MF presentó una cinética más lenta durante la maceración, produciendo vinos que no se diferenciaron significativamente de los elaborados por MT. Los mostos MC presentaron mayor extracción de polifenoles totales y antocianos durante la etapa prefermentativa, que se mantuvieron durante la fermentación alcohólica, obteniendo vinos con mayor intensidad colorante y mayor tonalidad respecto a los elaborados por MT. La maceración prefermentativa en caliente es una alternativa tecnológica que permite mejorar la extracción de polifenoles y potenciar el color de los vinos tintos Tannat,

Con el objetivo de evaluar el efecto de la ingesta de deoxinivalenol (DON) y de un adsorbente de micotoxinas en la producción de vacas lecheras, 32 vacas fueron asignadas a los siguientes tratamientos en un diseño de bloques completos al azar durante nueve semanas: oferta de 6 kg/día de concentrado/vaca con a) 0, b) 2,5, c) 5,0 o d) 5,0 ppm de DON más 0,1 % de un adsorbente de micotoxinas, equivalente a una oferta de 0, 15, 30 y 30 mg de DON/día, respectivamente. Los concentrados fueron formulados para ser isoenergéticos e isoproteicos, y se ofreció a todas las vacas la misma cantidad de pradera y ensilaje de maíz. El consumo de concentrado y la producción de leche no difirió entre tratamientos, pero la oferta de 30 mg/día de DON sin adsorbente disminuyó el porcentaje, el rendimiento de grasa y la producción de leche corregida a 4 % de grasa (LCG), e incrementó el recuento de células somáticas (RCS). La inclusión de un adsorbente en el concentrado con 5,0 ppm de DON evitó el aumento del RCS y la disminución de la producción de LCG. No hubo efecto del DON sobre la variación de peso o condición corporal, o la concentración plasmática de las enzimas aspartato aminotransferasa y gamma glutamil-transferasa. En condiciones pastoriles, una ingesta diaria mayor a 14 mg/vaca de DON redujo la productividad de vacas lecheras en lactancia temprana, lo que fue evitado mediante la inclusión de un adsorbente comercial.
Kłączowanie czy Bildung? Dydaktyka akademicka na rozdrożu
Authors: Stępkowski Dariusz
Published: February 2021

Academic science education is currently in crisis, which primarily involves the transmission of thinking skills as a priority task of the university. The author sketches a picture of this crisis by contrasting two theoretical models of teaching and learning at the university which are essentially identified with the terms “rhizoming” and Bildung. The presented ways of using the models in academic practice are used to consider the possibilities of overcoming the crisis and determining the conditions.
Biblioterapia w procesie socjoterapeutycznym dzieci i młodzieży – wykorzystanie potencjału
Authors: Świątek-Gruszka Jolanta
Published: February 2021

This article sets out to present possible application of bibliotherapy in the social therapeutic process. Bibliotherapy and social therapy share such elements as: education, correction of behavioural disorders, personality enhancement, and the prevention of social maladjustment. While analysing the goals of the aforementioned methods, a thesis has been proposed that they may be common for both. Bibliotherapy may serve as reinforcement of the social therapeutic process by enriching it and making it more enjoyable. Its goal is to build up the participants’ personal resources, supporting them in difficult situations, and providing a therapeutic impact. The article points out the key role that a literary text plays in the bibliotherapeutic process, and constitutes a starting point for bibliotherapeutic interactions. The article emphasises the potential of literature as a tool for the therapeutic and educational process, social rehabilitation and health improvement. Thus, social therapy may approach bibliotherapy as a way to enrich its educational and therapeutic offer.
Zajęcia z filozofii dla najmłodszych w opinii edukatorów
Authors: Wąsik Barbara
Published: February 2021

Due to my belief that classes in which children (preschool and primary learners) can philosophise require a specific attitude from the person conducting them, different from a typical attitude of most school teachers, I have decided to reconstruct the views of those people on various aspects of their activities. I was interested in their motivation, the goals which they set for themselves, the methods of their work, the didactic aids they use, as well as the assessment of their own efforts and the results of classes, including the prospects of the projects which are being realised. The research was qualitative. The internet survey was filled in by eight people mainly living in the big cities (among them seven females), most of whom had a higher education degree, generally in philosophy. By using consecutively three different criteria: the type of motivation which drives the examined people; the degree to which the projects they partake in are institutionalised; the type of public institution with which they cooperate, I discerned six types of teachers, whose views I described in detail. With regard to the represented views the group turned out to be almost uniform, although singular respondents attached different significance to individual issues.

The influence of defects in solid-state dielectric samples on the parameters of the electromagnetic response under deterministic acoustic influence on the control object is shown. The regularities of changes in the parameters of electromagnetic signals with variations and increases in the electric field strength vector relative to the contact of the sample materials and the defect are presented. It is shown that the amplitude-frequency parameters of the emitted electromagnetic signals are directly related to the acoustic impedance and conductivity of the contacting medium and the defect. The amplitudes of electromagnetic responses correspond to the distribution in time and space determined by mathematical modeling of mechanical stresses that occur in a defective system during the propagation of an acoustic pulse. Data on changes in the parameters of electromagnetic signals with an increase in the size of model defects in similar samples are presented.
La resilience en temps de pandemie au Cameroun: de la difficile distanciation a l’impossible enfermement social
Authors: Mbatchou Joseph Yannick
Published: February 2021

La COVID-19 est une pandémie à l’échelle planétaire dont la propagation a été facilitée par plusieurs vecteurs qui sont à la fois naturels et humains. La dangerosité du virus, sa mutation et la difficile maîtrise de ce dernier par les hommes de sciences font du SARS-COV 2 une menace qui n’épargne aucun pays. Pour éviter l’hécatombe des sociétés comme dans les récentes pandémies qu’a connu le monde, la résilience semble être une stratégie plausible pour protéger l’humanité. Face à l’angoisse, la psychose qui alimente les populations et la déficience d’un système sanitaire, les politiques camerounais ont instauré le port de masque obligatoire dans les lieux publics non pas pour briser la résilience; mais pour s’inscrire dans la continuité de la vie. Ce projet se propose, d’étudier l’intérêt épistémique de la résilience des Camerounais face à la pandémie du coronavirus. De même, il s’agit de clarifier le concept de distanciation sociale, voire physique qui semble avoir perdu son contenu au début de la crise face aux traditions des peuples. Dans un contexte comme celui du Cameroun où le secteur informel absorbe plus de la moitié du taux de chômage, l’enfermement social a évolué en dents de scie. La réalisation de cette étude emprunte les canons de la discipline historique. Pour mener à bien ce travail, nous avons utilisé les décrets, les circulaires de la Primature et ceux du Ministére de la santé publique afin d’analyser les dispositions qui ont été prises par les hommes d’Etat pour préserver la santé des individus. Ces archives ont été confrontées aux entretiens menés auprès des acteurs économiques et des ménages dans le but, d’évaluer l’impact desdites décisions dans le quotidien des populations. Les résultats de ce travail sont pluriels et permettent de savoir, que la résilience est un concept mis sur pied au Cameroun pour protéger les populations et limiter la propagation du virus. Il ressort également que les Camerounais ont du mal à respecter la distanciation physique car cette dernière n’entre pas dans leurs mœurs. C’est pourquoi, l’enfermement social qui a plus ou moins réussi draine avec lui plusieurs maux socioculturels.
