Bioactive components and the effect of aqueous leaf extract of Maesobotrya barteri (Baill.) Hutch. (Euphorbiaceae) on haematological profile in paracetamol-induced Wistar rats
Authors: Ogunka-Nnoka C. U. , Abbey B. W.
Published: January 2020

The study evaluates the bioactive components and the effect of aqueous leaf extract of Maesobotrya barteri (Baill.) Hutch. (Euphorbiaceae) on the haematological profile of paracetamol-induced Wistar albino rats. Standard methods were used in the proximate, phytochemical and haematological profile analysis. The results of the proximate composition revealed high values for crude fiber (49.13%), carbohydrates (16.33%) and protein (10.94%). Phytochemical studies showed the presence of alkaloids, flavonoids, saponins, phenols and tannins within the concentration range of 0.0003-94.68 µg/mL. Twenty-four hours after the last oral administration, the rats were sacrificed. Blood was obtained by cardiac puncture. Results of the haematological profile at different dose levels (200 mg/kg, 300 mg/kg and 500 mg/kg body weight) did not show any significant difference (p > 0.05) when compared with the control. A slight increase was observed in the erythrocytes (red blood cells, haemoglobin, packed cell volume and platelets). Meanwhile, a significant increase (p <= 0.05) was observed in the WBC and platelets of the groups induced with paracetamol only. However, administration of ascorbic and the sample extract reduced the white blood cells and platelet levels. The study revealed that M. barteri leaves contain an appreciable amount of nutrients, bioactive constituents and may serve as a blood booster.
Modified Carbon Nanostructures Obtained from Sugarcane Bagasse Hydrochar for Treating Chromium-polluted Water
Authors: Fathy Nady A. , El-Khouly Sahar M. , El-Shafey Ola I.
Published: January 2020

Background:

Application of nanotechnology in wastewater treatment is the solution to
cope with the conflict between people’s increasing demand for water and the world-wide water
shortage. The main goal of this study is to prepare modified carbon nanostructures (CNSs) from sugarcane
bagasse waste (SCB) as effective adsorbents for removing toxic Cr(VI) ions from their aqueous
solutions.

Methods:

The preparation of CNSs was performed via catalytic hydrothermal/carbonization of SCB.
The resultant CNSs sample was oxidized by oxidation with HNO3/H2O2 (O-CNSs) and then followed
by coating with diethylenetriamine (N-CNSs). Transmission electron microscope (TEM), scanning
electron microscope attached to energy-dispersive X-ray (SEM/EDX), fourier transform infrared
(FTIR) and nitrogen adsorption analyses were used to determine the morphology and surface properties
of CNSs. Adsorption and desorption studies of Cr(VI) ions onto these modified CNSs were investigated.
Effects of initial concentration of Cr(VI), pH of solution and temperature in the batch
mode were estimated. Adsorption studies were analyzed by Langmuir, Freundlich and Dubinin-
Radushkevich models. Pseudo-first-order, pseudo-second-order and intraparticle diffusion models
were undertaken to follow the adsorption mechanism.

Results:

The prepared samples composed of carbon nanotubes and graphene sheets were evident by
TEM and SEM. The adsorption of Cr(VI) is exothermic in nature, well-fitted with Langmuir, described
by pseudo-second order kinetic model and then is uncontrolled by intraparticle diffusion step.
It was found that the adsorption of Cr(VI) was higher uptake over O-CNSs (56 mg/g) than that by NCNSs
(44 mg/g). This was ascribed to that the first sample is enriched with acidic O-functional
groups and possessed higher specific surface area (188 m2/g). Desorption studies were achieved by
HNO3 and NaOH reagents for recovering the Cr(VI) from O-CNSs. Results revealed that about 90%
of Cr(VI) can be recovered by HNO3 more than that by NaOH till the third run.

Conclusions:

Two modified CNSs samples were successfully prepared from SCB. Adsorption of
Cr(VI) is highly relied on initial concentration of Cr(VI), pH and temperature. The main factors controlling
the adsorption behavior of Cr(VI) are the acidic functional groups and the accessible surface
area on O-CNSs. Furthermore, the O-CNSs attained high stability in recycling tests for Cr(VI) removal.

Authors: Asgharzadeh Mohammad , Rashedi Jalil , Poor Behroz Mahdavi , kafil Hossein Samadi , Zadeh Hossein Moharram , Ahmadpour Ehsan
Published: January 2020

Background:

Nowadays, due to the incidence of specific strains of Mycobacterium tuberculosis
and also an increase in the rate of drug resistant-TB, the mortality rate has been increased
by this disease. The identification of common strains in the region, as well as the sources of transmission,
is essential to control the disease, which is possible by using molecular epidemiology.

Objective:

In this survey, the studies utilizing the spoligotyping method in Muslim Middle East
countries are reviewed to determine their role in the control of TB.

Methods:

All studies conducted from 2005 to June 2016 were considered systematically in three
electronic databases out of which 23 studies were finally selected.

Results:

The average rate of clustering was 84% and the rate of recent transmission varied from
21.7% to 92.4%. The incidence of Beijing strains has been found to be rising in the abovementioned
countries. In Iran and Saudi Arabia known as immigration and labour-hosting countries,
respectively, rapid transmittable and drug-resistant Beijing strains were higher than those in other
Muslim Middle East countries.

Conclusion:

Considering the incidence of highly virulent strains, due to the increase in immigration
and people infected with HIV, tuberculosis, especially drug-resistant form, careful monitoring is
needed.

Authors: Yadav Om P. , Pahuja Gobind L.
Published: January 2020

Objectives:

The main objectives of this manuscript are to investigate and diagnose
rolling element bearing defects in its inception time.

Methods:

Vibration signal generated by the induction motor contains a series of frequency components
that have rich and viable information about bearing health conditions. Recently, the Maximum
Energy Concentration (MEC), measure of time-frequency spectrum has been employed to investigate
the small variations in low frequency biomedical signal spectrum. In this paper, the above technique
has been modified and applied to study the bearing defects of induction motor using vibration
signal and it is termed as Adaptive Modified Morlet Wavelet (AMMW) transform. Initially, this
proposed method was validated on two medium frequency synthetic time series signals in terms of
MEC measurement at different Signal to Noise Ratio (SNR).

Results:

The simulated results have depicted that the AMMW method provides excellent timefrequency
localization capability over other time-frequency methods like Morlet wavelet transform,
modified Morlet wavelet transform, adaptive S-transform and adaptive modified S-transform. Then,
this method has been applied to the standard database of vibration signal to determine interquartile
power for fault detection purpose and also fault index parameter termed as IFI has been analyzed to
detect small variation in vibration signals.

Резюме. Метою дослідження стало покращення лікування пацієнтів з облітеруючим атеросклерозом нижніх кінцівок, яким проводяться відкриті шунтуючі оперативні втручання на артеріях, шляхом вивчення частоти та причин тромбозів шунтів після реконструктивних операцій на різних артеріальних сегментах. Впродовж 3 років динамічно спостерігалися 93 такі хворі. У 81 хворого були виконані «одноповерхові» артеріальні реконструктивні втручання і у 12 – «двоповерхові». Було виявлено, що в осіб, у яких упродовж спостереження шунти затромбувалися, швидкість агрегації тромбоцитів та рівень фактора Віллебранда перед операцією були статистично значуще вищими, ніж у хворих без тромбозів шунтів (р=0,037 та 0,048). Частота тромбозів шунтів була також статистично значуще вищою у осіб з доопераційним активованим частковим тромбопластиновим часом, відхиленим у бік гіперкоагуляції (р=0,039). Серед осіб зі стенозами 50-70 % в аорто-клубовому сегменті та протяжними оклюзіями у стегново-підколінному сегменті, яким реконструктивні операції виконували лише на стегново-підколінному сегменті, частота тромбозів шунтів виявилася статистично значуще вищою, ніж у осіб, у яких стенози в аорто-клубовому сегменті були попередньо ліквідовані шляхом стентування зовнішньої чи загальної клубової артерії (р=0,041). Було також встановлено, що при відсутності адекватної вени, для стегново-підколінних шунтувань з дистальним анастомозом вище коліна допустимо використовувати алошунтування, а для стегново-гомілкових реконструкцій – алоаутошунтування. Проведення нового дослідження з вивченням частоти тромбозів шунтів у випадку протидії виявленим у цій праці предикторам може зумовити суттєве покращення результатів лікування таких хворих.

Резюме. Хіміотерапевтично-індукована периферична нейропатія є дозолімітуючим побічним нейротоксичним ефектом цілого ряду хіміопрепаратів, серед яких препарати платини, таксани, алкалоїдні препарати, а також нові таргетні препарати, зокрема бортезамід та ленолідамід. Типовим шляхом попередження периферичної нейропатії є редукція доз хіміопрепаратів або відмова від застосування таксанів, що, у свою чергу, негативно позначається на безпосередній ефективності та віддалених результатах лікування. Периферична нейропатія, викликана таксанами, негативно впливає на довготривалу якість життя пацієнтів, характеризується тривалим персистуючим перебігом та в 40 % випадків призводить до інвалідизації.

Патофізіологічний механізм таксан-індукованої нейропатії на даний час не є цілковито розкритим та зрозумілим. Пригнічення деполяризації тубуліну і, як наслідок, дисфункція мікротрубочок наразі є найбільш загальноприйнятим поясненням нейротоксичності таксанів. Даних морфологічного дослідження периферичних нервів у пацієнтів у науковій літературі бракує. Біопсія литкового нерва (nervus suralis) із наступним вивченням морфологічних змін при застосуванні паклітакселу та доцетакселу проводилась тільки у декількох пацієнтів. Більше того, вичерпні дані морфологічного дослідження неоднозначні та суперечать загальноприйнятій теорії патогенезу нейропатії.

Для того, щоб своєчасно та ефективно попереджати і запобігати дану побічну реакцію, необхідно знати причини, що призводять до розвитку периферичної нейропатії, і розуміти, які клітинні структури і механізми беруть у цьому участь. У даній статті наведено огляд літературних даних, присвячених питанню розвитку периферичної нейропатії, індукованої таксанами.
ДОСЛІДЖЕННЯ МЕХАНІЗМІВ ОНКОЛОГІЧНОГО РИЗИКУ У ХВОРИХ З ЦУКРОВИМ ДІАБЕТОМ 2 ТИПУ.
Authors: Вацеба Т. С. , Соколова Л. К.
Published: January 2020

Резюме. Метою дослідження було вивчити механізми формування онкологічного ризику у пацієнтів із цукровим діабетом (ЦД) 2 типу шляхом визначення залежності вмісту фосфорильованого PRAS40 (фосфо-PRAS40) від рівнів інсуліну та IGF-1.
Матеріали та методи. Обстежено 100 пацієнтів, які розділені на групи: І – здорові (n = 14); ІІ – хворі з ЦД 2 типу (n = 28); ІІІ – хворі з раком без ЦД (n=34); IV – з поєднанням раку і ЦД. До ІІІ і IV груп залучені хворі з раком молочної залози (МЗ), ендометрію (ЕМ) і підшлункової залози (ПШЗ).
Імуноферментним методом в мононуклеарах периферичної крові (МНПК) визначали рівні інсуліну, IGF-1 та фосфо-PRAS40, використовуючи діагностичні набори Insulin ELISA EIA-2935, IGF-1 600 ELISA EIA-4140 (DRG, Німеччина) та ELISA КНО0421 (Іnvitrogen, США). Компенсацію ЦД оцінювали за рівнем HbA1c. Аналіз даних проводили за допомогою програми Statistica 12.0 (StatSoft Inc., США).
Результати. Ожиріння та достовірна гіперінсулінемія виявлені у пацієнтів II групи з ЦД 2 типу і в хворих ІІІ і IV груп із раком МЗ та ЕМ (Р < 0,05). Підвищений рівень IGF-1 виявлений у хворих IІ і ІІІ груп (Р < 0,05), а також у жінок IV групи з раком МЗ та ЕМ (Р < 0,05). Рівень фосфо-PRAS40 був підвищений у хворих ІІ групи і в жінок ІІІ групи з раком МЗ та ЕМ (Р < 0,05), а в пацієнтів IV групи – знижений (P < 0,05). Декомпенсований ЦД мали 53,4% пацієнтів ІІ групи і 75,0% хворих IV групи.
Висновки. Ожиріння, гіперінсулінемія та підвищений рівень IGF-1 є факторами активації сигнального шляху PI3K/Akt/mTOR у хворих із цукровим діабетом 2 типу. Вміст фосфо-PRAS40 відображає активацію PI3K/Akt/mTOR і може свідчити про схильність жінок з діабетом до раку молочної залози та ендометрію. Рак ПШЗ із тривалістю діабету до 3-х років, не асоційований з ожирінням та гіперінсулінемією, може бути проявом вторинного діабету типу T3cDM, зумовленого онкологічним процесом в залозі.
Two-Way Text Messaging to Support Self-Care and Delivery of an Online Sexual Health Service: Mixed Methods Evaluation (Preprint)
Authors: Shanks Sarah , Morelli Alessandra , Ardines Elena , Holdsworth Gillian , Baraitser Paula
Published: January 2020

BACKGROUND

Digital health care is increasingly used to improve health service accessibility and reduce costs. Remote health care requires a significant self-management role for service users, and this generates information provision and support needs that should be reflected in service planning. SMS text messaging offers a convenient and low-cost method of communication and is increasingly used across digital health care services to provide remote support.

OBJECTIVE

The aim of this study was to quantify the number of messages generated through user interaction with a two-way SMS text messaging support service within an online sexual health service and to thematically explore the content of the messages and type of support required to facilitate self-management.

METHODS

The content of all SMS text messages received by an online sexual health service was analyzed from April 4, 2018, to July 5, 2018. Messages were classified as being either administrative or clinical in nature and service or user initiated. For those messages that were both clinical and user initiated, a qualitative thematic analysis was completed to fully describe the content of the interactions.

RESULTS

A total of 267 actionable messages were generated per 1000 orders requested through the service. Of the 8562 messages, 5447 (63.62%) messages were administrative and 3115 (36.38%) were clinical. Overall, 4306 of the 8562 messages (50.29%) responded to service-generated queries reflecting the public health and clinical responsibilities of an online provider, and 4256 (49.71%) were user-generated queries, demonstrating a willingness by users to proactively engage with a two-way SMS text messaging support service. Of the 3115 clinical messages, 968 (31.08%) clinical messages were user initiated and shared personal and complex clinical information, including requests for help with the self-testing process and personalized clinical advice relating to symptoms and treatment.

CONCLUSIONS

This study demonstrates the willingness of users of an online sexual health service to engage with two-way SMS text messaging and provides insight into the quantity and nature of the support required to facilitate service delivery and self-care. Further work is required to understand the range of clinical problems that can be managed within this medium.

Authors: Bendre Dr Salil , PS Dr Shankar , Korukonda Dr Krishnaprasad ,   EMA Expert Panel
Published: January 2020

BACKGROUND

Cough is a common yet distressing symptom that results in significant health care costs from outpatient visits and related consultations.

OBJECTIVE

Understanding the pathobiology of cough in recent times has undergone an evolution with Cough hypersensitivity syndrome (CHS) being suggested in most cases of dry cough. In case of productive cough however ancillary mechanisms including impaired Mucociliary clearance in addition to hypermucosecretory bronchospastic conditions of Smoker’s cough, asthma-COPD overlap syndrome, AECB, allergic bronchopulmonary aspergillosis need to be critically addressed while optimizing patient care with symptomatic therapy in such cases while avoiding its misuse in most of the situations

METHODS

In this review, evidence-based graded recommendations on use of Pro- & Antitussives as a Position Paper were developed based on the Level and Quality of Scientific evidence as per Agency of Health Care and Quality Systems (AHRQ) and Clinical insights, offered by a multidisciplinary EMA panel in India.

RESULTS

Management of acute or chronic cough involves addressing common issues of environmental exposures and patient concerns before instituting supportive therapy with antitussives or bronchodilatory cough formulations containing mucoactives, anti-inflammatory or Beta-2 agonist agents

CONCLUSIONS

The analyses provides a real world approach on the management of acute or chronic cough in various clinical conditions including with Pro- or antitussive agents
How the Use of a Patient-Accessible Health Record Contributes to Patient-Centered Care: Scoping Review (Preprint)
Authors: Benjamins Janine , Haveman-Nies Annemien , Gunnink Marian , Goudkuil Annemieke , de Vet Emely
Published: January 2020

BACKGROUND

Worldwide, patient-centered care is becoming a widely used concept in medical practice, getting more and more attention because of its proven ability to improve quality of care and reduce costs. Although several studies show that patient-accessible electronic health records (PAEHRs) influence certain aspects of patient-centered care, the possible contribution of PAEHR implementation to patient-centered care as a comprehensive concept has not, to our knowledge, been structurally evaluated to date.

OBJECTIVE

The objective of this study is to review whether and how the use of PAEHRs contributes to patient-centered care both in general and among specific population groups.

METHODS

We followed PRISMA Extension for Scoping Reviews reporting guidelines. We identified literature in 5 databases, using the terms “patient-accessible medical records,” “patient experiences,” and “professional experiences” as key concepts. A total of 49 articles were included and analyzed with a charting code list containing 10 elements of patient-centered care.

RESULTS

Studies were diverse in design, country of origin, functionalities of the investigated PAEHR, and target population. Participants in all studies were adults. Most studies reported positive influence of PAEHR use on patient-centered care; patient accessible health records were appreciated for their opportunity to empower patients, inform patients about their health, and involve patients in their own care. There were mixed results for the extent to which PAEHRs affected the relation between patients and clinicians. Professionals and patients in mental health care held opposing views concerning the impact of transparency, where professionals appeared more worried about potential negative impact of PAEHRs on the patient-clinician relationship. Their worries seemed to be influenced by a reluctant attitude toward patient-centered care.
Disadvantaged groups appeared to have less access to and make less use of patient-accessible records than the average population but experienced more benefits than the average population when they actually used PAEHRs.

CONCLUSIONS

The review indicates that PAEHRs bear the potential to positively contribute to patient-centered care. However, concerns from professionals about the impact of transparency on the patient-clinician relationship as well as the importance of a patient-centered attitude need to be addressed. Potentially significant benefits for disadvantaged groups will be achieved only through easily accessible and user-friendly PAEHRs.
The Impact of Brexit on the Pharmaceutical Supply Chain of the United Kingdom: Scoping Review Protocol (Preprint)
Authors: Milne-Ives Madison , Lam Ching , van Velthoven Michelle , Meinert Edward
Published: January 2020

BACKGROUND

The continuing uncertainty around Brexit has caused concern in the pharmaceutical industry and among health care professionals and patients. The exact consequences of Brexit on the pharmaceutical supply chain in the United Kingdom will depend on whether a deal is reached and what it entails, but it is likely to be affected by the withdrawal of the United Kingdom from the European Union. Regulatory issues and delays in supply have the potential to negatively affect the ability of UK residents to receive an adequate and timely supply of necessary medicines.

OBJECTIVE

The purpose of this protocol is to provide an overview and critical analysis of current perspectives on the effect of Brexit on the UK pharmaceutical supply chain.

METHODS

The PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews) guidelines will be used to structure this protocol. A systematic search of MEDLINE, EMBASE, PsycINFO, Healthcare Management Information Consortium (HMIC), Cochrane, Web of Science, Business Source Complete, EconLit, and Economist Intelligence Unit will be conducted, as well as a Google and Nexis.UK search for grey literature such as reports, opinion pieces, and press releases. Two reviewers will independently screen the titles and abstracts of identified references and select studies according to the eligibility criteria. Any discrepancies will then be discussed and resolved. One reviewer will extract data from the included studies into a standardized form, which will be validated by a second reviewer. Risk of bias will be assessed using the Cochrane Collaboration Risk of Bias tool for any randomized controlled trials; quality will be assessed using the relevant Critical Appraisal Skills Programme (CASP) checklists; and grey literature will be assessed using the Authority, Accuracy, Coverage, Objectivity, Date, Significance (AACODS) checklist. Outcomes include the agreement between sources on the potential, likelihood, and severity of the consequences of Brexit on the UK pharmaceutical supply chain.

RESULTS

Results will be included in the scoping review, which will be published in 2020.

CONCLUSIONS

This scoping review will summarize the currently expected consequences of Brexit on the UK pharmaceutical supply chain.

Improving the Reproducibility of LaTeX Documents by Enriching Figures with Embedded Scripts and Data
Authors: Jacobs Christian Thomas
Published: January 2020

The introduction of open-access data policies by research councils, the enforcement of best practices, and the deployment of persistent online repositories have enabled datasets which support results in scientific papers to become more widely accessible. Unfortunately, despite this advancement in the curation/publishing workflow, the data-driven figures within a paper often remain difficult to reproduce. Plotting or analysis scripts rarely accompany the manuscript or any associated software release; and even if they do, it may be unclear exactly which version was used. Furthermore, the precise commands and parameters used to execute the scripts are often not included in a README file or in the paper itself. This paper introduces a new open-source digital curation tool, Pynea, for improving the reproducibility of LaTeX documents. Each figure within a document is enriched by automatically embedding the plotting script and data files required to generate it, such that it can be regenerated by readers of the paper in the future. The command used to execute the plotting script is also added to the figure's metadata, along with details of the specific version of the script used (if the script is tracked with the Git version control system). If the document is to be recompiled with a figure that has since changed, or had its plotting script or data files modified, the figure is regenerated such that the author can be confident that the latest version of the figure and its dependencies are included.

Published: January 2020

El uso de fibras naturales (yute, coco, caña, etcétera.) y desechos agroindustriales (ceniza, cascarilla de arroz, etcétera) como materiales de refuerzo en la obtención de materiales compuestos ha ido en aumento, debido a que se consideran de bajo costo y fácil obtención. Se han estudiado las interacciones de los materiales de refuerzo, así como las propiedades físicas, químicas y mecánicas que le transfieren al material. En esta investigación se desarrolló un material con una matriz de cemento portland compuesto (CPC-30R) reforzado con agregado fino de carboncillo de bagazo de caña (CBC) y fibra de bagazo de caña de azúcar (FO). La FO fue modificada superficialmente, inicialmente se sometió a un proceso de deslignificación con NaOH a 6.0 % y blanqueo con NaClO2 V/V a 0.5 % y H2O2 V/V a 0.34 %, para remoción de hemicelulosa y obtener una fibra con mayor exposición de celulosa, posteriormente se modificó con dos tipos de compuestos silánicos, Isooctyl-trimethoxylsilane a 97 % y Trimethoxy-methylsilane a 95 %. La FO se analizó mediante espectroscopia de infrarrojo con Transformada de Fourier (FTIR) y se evaluó su hidrofobicidad en un sistema Agua-Tolueno. La FO tratada se mezcló con cantidades diferentes de CPC-30R y agua. La morfología del material compuesto se observó mediante Microscopía Electrónica de Barrido (SEM), la cual mostró la interacción del agregado fino de CBC en la matriz de CPC-30R. El comportamiento térmico del material se evaluó en un equipo de placa caliente aislada, conforme a la norma ASCTM – C177, obteniendo resultados de conductividad térmica de 0.21 W/m °C.

Published: January 2020

La gestión de implementación de nueva tecnología en empresas manufactureras se enfrenta a problemas complejos como recursos humanos y financieros escasos y cambiantes, avances tecnológicos que superan la capacidad de infraestructura y de compatibilidad, necesidad de reconfiguración inmediata y un cambio constante de requisitos. Este artículo propone un modelo de gestión de ingeniería utilizando el enfoque de Pensamiento Sistémico y Modelado (PSyM) en sus 5 fases: la estructuración del problema, modelado de lazo causal, modelado dinámico, planificación y modelización de escenarios y por último la implementación y aprendizaje organizacional. Su objetivo es mejorar la actividad de implementación de nueva tecnología contemplando la herramienta de modelado Vensin® PLE, permitiendo estudiar su reacción a ciertos cambios a lo largo del tiempo; el modelo se validó sometiéndolo a las siguientes verificaciones: el diagrama de lazo casual que corresponde a la declaración del problema, el modelo es dimensionalmente válido, documentación adecuada de cada ecuación en el modelo, el modelo no produce valores irreales, el comportamiento del modelo es plausible, el modelo mantiene la “conservación del flujo” y cada ecuación tiene sentido cuando sus entradas toman valores extremos. Se consideró la experimentación con un esquema de simulación de 22 parámetros de políticas agrupadas en 4 sectores estratégicos: tecnológico, de ingeniería, recursos humanos y finanzas, utilizando la capacidad de evaluación del modelo, se identificaron las debilidades de cada sector y se propone un escenario para mejorarlas. Al analizar el modelo de Gestión de Ingeniería e Introducción de Nueva Tecnología (GIINT) los gerentes pueden considerar las decisiones en función al efecto de estas en la actividad de implementación de nueva tecnología de su empresa, pueden identificar los elementos que influyen en la implementación de tecnología y relacionarlos con los efectos en diferentes áreas de la empresa.
“Lo realizamos para todos, para que todos estemos mejor en esta tierra”
Authors: Franco García Martha Josefina
Published: January 2020

Este estudio se realizó en una escuela de educación indígena, en torno al eje de la gestión escolar. Nuestro objetivo fue analizar las funciones que el Estado delega a la escuela, en un contexto sociohistórico particular, e identificar lo que intenta instituir en cuanto a orden y normatividad, así como la manera en que el colectivo escolar se organiza. La metodología empleada fue la etnografía, lo cual permitió reconocer que, más allá de los planteamientos de la SEP sobre autonomía de gestión, la escuela tiene una historia que condensa aspectos como participación, responsabilidad, trabajo comunitario, toma de decisiones, gestión y acuerdos. Con estas acciones, el colectivo no sólo logra que opere la escuela, también instituye su legitimidad mediante el vínculo cultural que cohesiona a partir de los compromisos que se generan en el día a día.

El ciberacoso es un problema complejo que afecta el desarrollo psicosocial de los adolescentes. El presente estudio se propuso analizar las diferencias en variables personales, familiares, escolares y comunitarias de estudiantes con y sin conductas de ciberacoso. Se seleccionaron aleatoriamente 1,488 estudiantes de educación media superior de Sonora, 669 (45 por ciento) del sexo masculino (M edad=15.88, DE=2.20 años) y 819 (55 por ciento) del femenino (M edad=15.78, DE=2.22 años). Los resultados del modelo de regresión logística mostraron que la empatía, el apoyo parental, el apoyo docente y los activos de la comunidad disminuyen la probabilidad de ciberacoso, mientras que la violencia familiar y el acoso tradicional favorecen la ciberagresión. Esta información sugiere que la prevención del ciberacoso en la adolescencia debe incluir intervenciones enfocadas en promover el desarrollo socio-emocional y en fortalecer el apoyo social (parental, docente y comunitario) disponible para los adolescentes.
¿Qué significa evaluar?

Evaluar y proveer retroalimentación de aprendizajes es una tarea compleja del profesorado y constituye un desafío para la formación inicial docente, ya que coexisten diversos enfoques y representaciones sobre la evaluación en la cultura escolar. Sin embargo, son escasas las investigaciones que ofrecen evidencia empírica sobre cómo son dichas representaciones en futuros profesores. El presente estudio explora los significados que 112 estudiantes de Pedagogía de una universidad del centro sur de Chile atribuyen a la evaluación y la retroalimentación. Se utilizó la técnica de redes semánticas como método para dar cuenta de las representaciones implícitas a partir de constructos naturales. El análisis cuantitativo de las respuestas indica que la mayoría de los términos relacionados con evaluación se vinculan al discurso de la racionalidad técnica, mientras que el concepto de la retroalimentación se asocia a procesos cognitivos y de ejecución; estos hallazgos podrían relacionarse con una transición hacia la evaluación formativa.

EM RESGATE DA HONRA, DOS VALORES FAMILIARES E DO FORTALECIMENTO DA NAÇÃO: LIGA DA DEFESA NACIONAL

A constituição da “moderna” ordem republicana associava-se à ideia de representatividade, de parceria, engajamento, socialização de um espaço, de uma causa, de um movimento de agentes sociais em disputa pela construção de uma identidade nacional. A década de 1910 no Brasil é marcada por uma fase de desestabilização social, representada pelo protagonismo de uma parcela da sociedade politicamente ativa, hegemônica, que se apoiava no discurso de transformação do país. Nessa direção, ampliava-se o envolvimento dos setores militares e de intelectuais pertencentes às instituições sociais de prestígio, como o IHGB, a ABL, alinhados a esses setores. Com o intuito de se problematizar espaços e agências sociais responsáveis pelo processo educativo, o estudo das Ligas nesse período sinaliza a existência de organizações que se articulam para a defesa nacional, a organização do trabalho e a propagação da instrução popular. Propõe-se investigar a Liga da Defesa Nacional (LDN), pela análise dos discursos e dos efeitos de verdade que produz (FOUCAULT, 2001), por via das notícias disseminadas na imprensa carioca, buscando-se compreender o seu papel a partir de diferentes versões da história (CHALHOUB, 2012). À frente desse movimento, destaca-se a liderança de Olavo Bilac, tendo na associação uma ideia de programa social, “com vistas antes de cuidar da educação cívica, buscar na instrução primária, profissional e na militar, mudar a face das coisas” (O PAIZ, 28/10/1915, p.01). Entre seus propósitos, buscava-se o combate ao anarquismo, ao estrangeirismo, aos comícios e às greves, na tentativa do resgate da honra, dos valores familiares e do fortalecimento da nação.
Spatial organisation concept of two-entrance apartment
Authors: Alfirevic Djordje , Alfirevic Simonovic
Published: January 2020

The location of the entrance and its relation to the main functional
apartment groups in multi-storey, multi-family buildings, is to a great
extent determined by the organizational concept of the apartment. The
apartments with auxiliary entrances are less present in practice, majority
of apartments fit the spatial frame of the building itself. The apartments
can border with the next apartment on the same floor, be oriented towards
one or more facades, but what is of key importance in determining the number
of apartment entrances and their positioning is the size of contact zone
between the apartment and common communication areas, as well as the
configuration of the apartment. The aims of this paper include the analysis
of the main positions of the entrance and the concepts of apartment
organization that they determine, analysis of characteristic concepts of
two-entrance apartments in multi-storey, multi-family buildings and
re-examination of the relation between the introduction of the additional
entrance and the necessity of having constant or occasional segregation of
certain activities in them.
Gis application in analysis of erosion intensity in the Vlasina River Basin

Published: January 2020

This paper analyses the state of erosion intensity in the Vlasina River
Basin, the right tributary of the Juzna Morava River. To determine the
erosion intensity (Z) and sediment production, the Gavrilovic method was
used, in combination with the bare-soil index (BSI), with the application of
geographic information systems (GIS) and multispectral satellite imagery. An
erosion coefficient of 0.31 has been identified in the territory of the
Vlasina River Basin, which has an area of 1,061.72 km?. The prominent
vertical fragmentation of the relief, large amount of precipitation in the
source parts, density of the river network (1.65 km/km2), which is above the
average river network density in Serbia, as well as inadequate land
exploitation, are the main reasons why it is necessary to monitor the
erosion intensity in the Vlasina River Basin. The annual production of the
sediment is 462,496.30 m?, while the value of specific sediment production
is 435,47 m?/km?/year. This study represents the attempt to apply modern
technologies to d1etermine the intensity of erosion in the Vlasina River
Basin, and the results obtained could be used for more adequate management
of land and water resources, sustainable planning of the forest ecosystems
and environmental protection.
Space, agglomeration economies and urban development
Authors: Vracarevic Bojan
Published: January 2020

In the major theories of economic development, the spatial aspect has often
been neglected. Within the evolution of regional development theories, not
only is there a shift in focus from exogenous to endogenous factors, but
also an increasing importance of human capital in the development process.
Agglomeration economies are ultimately driven by savings in transport costs,
related not only to the exchange of goods and services, but also to people
and ideas. Large cities play crucial role in knowledge spillover because the
interaction of educated and creative people stimulates innovation. Also, it
is obvious that there is a very pronounced feedback principle between urban
growth and the knowledge spillover. Contemporary urbanization trends are
perfectly matched with the technological advances of the new age which led
to sharp decrease of costs of communication and transfer of information.
These processes (that trigger pronounced agglomeration diseconomies, such as
pollution, rising cost of living and congestion), accompanied by the
demographic explosion that is especially evident in developing countries,
bring into focus the problems of urban development.
KONFLIK PULAU IEO DENGAN CINA DAN DILEMA ALIANSI KORSEL – AS
Authors: Jaegyu Park
Published: January 2020

Tulisan ini menganalisa hubungan Korea Selatan dengan Amerika Serikat sebagai aliansi militer asimetris untuk menjelaskan Strategi Korsel pada konflik Pulau Ieo dengan Cina. Sebagaian besar, kajian terdahulu mengenai topik ini telah menjelaskan pentingnya keamanan Aliansi Korea Selatan dengan Amerika Serikat, historis dan politik– ekonomi. Namun, kajian-kajian tersebut belum menjelaskan mengapa Korea Selatan mengembangkan Pangkalan Angkatan Laut Pulau Jeju untuk melawan Cina. Dengan menggunakan konsep dilema aliansi, tulisan ini menjelaskan rezim, diplomasi Aliansi Amerika Serikat terhadap ancaman Korea Utara dan Cina sebagai faktor-faktor yang menjadi latar belakang pembangunan pangkalan Angkatan Laut baru di dekat daerah Pulau Ieo. Temuan tulisan ini menunjukkan bahwa diplomasi Korea Selatan tentang Aliansi tersebut merupakan Strategi Cooperate untuk tidak terjadi Penolakan oleh AS.
KERJA SAMA PEMBERANTASAN PENDANAAN TERORISME DI ASIA TENGGARA
Authors: Leatemia Max Fredrik
Published: January 2020

Tulisan ini menganalisis kerja sama regional di bidang pemberantasan pendanaan terorisme (PPT) antara negara-negara Asia Tenggara. Berbagai kajian sebelumnya telah membahas faktor-faktor yang mengkonstruksi respon negara-negara Asia Tenggara terhadap terorisme, beserta faktor-faktor yang menghambat upaya kontra terorisme di kawasan. Kendati demikian, kajian-kajian tersebut belum secara spesifik menjawab permasalahan pendanaan terorisme yang masih tinggi di Asia Tenggara, khususnya yang berkaitan dengan upaya regional untuk menanggulangi isu tersebut. Dengan menggunakan teori Regional Security Complex, tulisan ini akan menjelaskan polaritas serta struktur sosial yang membentuk karakteristik kerja sama PPT antar unit-unit di kawasan Asia Tenggara, maupun dengan aktor eksternal lainnya. Fokus dari penelitian ini adalah pada aspek pendanaan dari kelompok - kelompok teroris transnasional yang aktif paska Serangan September 2001 seperti Al-Qaeda dan Islamic State (IS). Oleh karena itu, pembahasan mengenai upaya PPT di Asia Tenggara pun akan difokuskan pada lima negara yang menghadapi ancaman dari kelompok-kelompok tersebut, yakni Indonesia, Filipina, Malaysia, Singapura dan Thailand. Temuan tulisan ini menunjukkan bahwa karakteristik kerja sama PPT di kawasan Asia Tenggara lebih dipengaruhi oleh kekuatan eksternal kawasan, sementara struktur sosial antar unit-unit internal kawasan tidak dominan. Kondisi ini pada akhirnya membuat kerja sama antar negara-negara Asia Tenggara tidak efektif untuk mengatasi pendanaan terorisme di kawasan.

DISKURSUS FEMINISME TRANSNASIONAL: PENGARUH INTERSEKSIONALITAS DALAM AGENDA KEAMANAN MANUSIA DI ASIA TENGGARA
Authors: Afriantari Rini
Published: January 2020

The emergence of feminism after global political depolarization after September 11, 2001, has a strategic role in designing the security agenda of a sovereign country with the emergence of the intersexional paradigm. In Southeast Asia, the excitement of the securitization of the non-traditional security agenda sprang up among regional authorities. Unfortunately, the security depolarization agenda is not followed by gender analysis where the state still uses realism among patriarchal global political hierarchies and excludes women in the global political arena. In this paper, the author will analyze how intersexionality in the agenda of human security in Southeast Asia emphasizes the discourse of transnational feminism.
