Las experiencias traumáticas en la infancia durante el confinamiento por la pandemia mundial por Covid-19 se han incrementado, el ministerio de salud y protección social ha informado que el aislamiento físico aumentó las alteraciones de la salud mental (ansiedad, depresión y estrés postraumático) en los niños, niñas, adolescentes y jóvenes así mismo se generó un mayor reporte de casos a nivel nacional por diferentes tipos de violencia en el contexto de las relaciones familiares. Se analiza la posible relación entre experiencias traumáticas en la infancia y Covid 19 a partir de una revisión documental entre marzo y noviembre de 2020, la estrategia de búsqueda fue: -traumatic childhood experience and covid-19- -childhood emotional abuse and covid-19- -childhood neglect abuse and covid-19- -childhood physical abuse and covid-19- -childhood violence or intrafamiliar or poverty and covid-19-, en las bases de datos: EBSCO, Google Scholar, PubMed y Science Direct. Se encontró que durante la pandemia por Covid-19 se ha intensificado los factores de riesgos psicosociales que propicia experiencias adversas durante la infancia, requiriéndose mayor atención en salud mental en la población colombiana.
Población callejera en Brasil y Colombia: una propuesta de creación del “Observatorio de las Calles”
Authors: Adoryan Machado Maria Luiza
Published: March 2022

Este ensayo presenta algunas líneas críticas y reflexivas sobre una propuesta de investigación que tiene como interés central el fenómeno social “situación de calle” en Brasil y Colombia. Actualmente tenemos algunos estudios producidos sobre el fenómeno de la situación de calle y vemos que cada territorio (ciudad, Estado, país) instrumentaliza estudios, encuestas e investigaciones en general, con el fin de garantizar los derechos de una población que vive al margen. En Brasil hemos hecho importantes avances en la agenda pública desde el año 2000 a través de luchas y resistencias sociales para garantizar los derechos de la población callejera. Sin embargo, las tasas siguen siendo alarmantes por el número de personas que hacen de las calles sus hogares, el escenario de las relaciones interpersonales, el autocuidado y auto sostenimiento. Lo que se configura cómo una cuestión social. En Colombia vemos que las primeras líneas legislativas específicas sobre la población en situación de calle toman forma en 2013 a través de la Ley 1641 (2013). Como propuesta de intervención, teniendo en cuenta la importancia del trabajo que se puede hacer a través de un observatorio, la importancia de las redes, el amplio acceso y alcance, se afirma que la creación de un observatorio específico sobre la situación de calle como un tema social en el que se puede trabajar de manera transdisciplinaria puede ser un paso importante para los derechos de miles de personas que viven en las calles de Brasil y Colombia.
El trasegar hacia los saberes colectivos
Authors: Clavijo Zapata Sandra Juliet
Published: March 2022

El presente artículo pretende develar lo que se ha entendido en Occidente por conocimiento; para ello nos serviremos de un trasegar por tres importantes ámbitos de este, a saber, el surgimiento del conocimiento como logos a la manera griega de comprender el término; el momento que se instaura en la Modernidad y la acepción de ciencia clásica, y finalmente, el denominado pensamiento crítico manifiesto en la Escuela de Frankfurt. Exhortando al lector a pensar el conocimiento como un concepto móvil, inacabado y siempre en potencial construcción.
Foreign capital inflows, trade openness and output performance in selected sub-Saharan African countries
Authors: Damson Nthangu Noel , Gerry Bokana Koye
Published: March 2022

This study empirically examined the dynamic impact of foreign capital inflows and trade openness on output performance and national productivity in 31 selected countries in sub-Saharan Africa (SSA) between 1985 and 2018. The study employed random effects and fixed effects models to estimate the coefficients. However, the results from the two models portray similar behaviors. Both estimates revealed a significant relationship between output performance and the independent variables. This suggests that the macroeconomic variables examined are good explanatory variables for analyzing the determinants of output performance and national productivity in the SSA region. The study further found that foreign capital inflows, trade openness and inflation rate have a positive and significant influence on output performance and national productivity. In contrast, exchange rate and interest rate exhibited a negative and significant relationship with such output performance. This result implies that policymakers in SSA countries must formulate policies that can successfully ensure trade openness and promote foreign capital inflows so as to stimulate national productivity and boost output performance in the region. Therefore, it can be concluded that foreign capital inflows and trade openness affect the industrial sector in contributing to output performance and national productivity in the SSA countries.

Authors: Carneiro Ana Carla , Meneguin Joziane , dos Santos Paula , Corazza Marcela , Prete Maiyara Carolyne , Rinaldi Andrelson Wellington , Tarley César Ricardo
Published: March 2022

Metal-organic framework (MOF) UiO-66 was synthesized and evaluated as solid-phase extractor support for cadmium preconcentration in a micro-flow injection system coupled to thermospray flame furnace atomic absorption spectrometry (TS-FF-AAS) detection. The adsorbent was characterized by X-ray diffraction, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), Raman spectroscopy, and textural data from N2 adsorption/desorption isotherm data. The optimized conditions were achieved by loading 10.0 mL of a sample, containing 0.05 mol L-1 of phosphate buffer solution at pH 8.0, at a high flow rate of 10.0 mL-1 through 20.0 mg of UiO-66 packed into a mini-column, followed by elution with 1.0 mol L-1 HCl. At these conditions, the method presented a preconcentration factor of 35.7, limit of detection of 0.03 μg L-1 and a dynamic linear range from 0.1 to 8.0 μg L-1. The adsorption performance of UiO-66 towards cadmium was not influenced by Pb2+, Hg2+, Fe2+, Co2+, Cu2+, Ni2+, Zn2+, Mg2+ and Ca2+ ions. Analysis of different waters samples (tap water, physiological solution, mineral water, and lake water) was carried out without matrix interference, yielding recovery values ranging from 92.0 to 111.9%.
O que é governança da internet? - uma revisão sistemática de literatura
Authors: Rocillo Paloma , Duarte Felipe , Roman Juliana
Published: March 2022

As diferentes concepções sobre governança da internet mobilizam esse termo de formas distintas a depender dos atores e interesses envolvidos. O problema central deste estudo foi compreender o arcabouço do conceito de governança da internet. Para isso, foi realizada revisão sistemática de literatura, aliando análise qualitativa e quantitativa de aspectos relevantes para examinar os elementos estruturantes da governança da internet e a localização das discussões acadêmicas a seu respeito. Observou-se predominância da adoção do conceito estabelecido na Cúpula Mundial da Sociedade da Informação nas 36 publicações analisadas. Algumas ainda sugerem revisões e acréscimos conceituais, principalmente em relação à concepção do modelo multissetorial, à exclusão de elementos práticos e informais desse domínio e à relação deste domínio à administração dos recursos mobilizados na rede. Identificou-se ainda que a consolidação de uma definição específica sobre termo é uma demanda secundária se comparada à necessidade da moldura teórica da governança da internet abarcar práticas e atores que ainda não são reconhecidos como pertencentes a este campo.

In this work, we investigated the possibility of using a nanoporous Ge layer (p-Ge) formed by implantation with Ag+ ions on a single crystal c-Ge substrate as an anode electrode for a lithium-ion battery. For this, ion implantation of c-Ge plates was carried out at an energy of E = 30 keV, a current density in the ion beam of J=5 μA/cm2, and a dose of D=1.3·1016 ion/cm2. It is shown that the obtained spongy Ag:p-Ge layers, consisting of intertwining Ge nanowires, demonstrate a high Coulomb efficiency (> 97%) after the first cycle and show up to 79.5% of reversible capacity after 1000 cycles.

Managing Diabetes Using Mobiab: Long-Term Case Study of the Impact of a Mobile App on Self-management
Authors: Burda Václav , Mráz Miloš , Schneider Jakub , Novák Daniel
Published: March 2022

Background

This paper describes the development of a mobile app for diabetes mellitus (DM) control and self-management and presents the results of long-term usage of this system in the Czech Republic. DM is a chronic disease affecting large numbers of people worldwide, and this number is continuously increasing. There is massive potential to increase adherence to self-management of DM with the use of smartphones and digital therapeutics interventions.

Objective

This study aims to describe the process of development of a mobile app, called Mobiab, for DM management and to investigate how individual features are used and how the whole system benefits its long-term users. Using at least 1 year of daily records from users, we analyzed the impact of the app on self-management of DM.

Methods

We have developed a mobile app that serves as an alternative form to the classic paper-based protocol or diary. The development was based on cooperation with both clinicians and people with DM. The app consists of independent individual modules. Therefore, the user has the possibility to use only selected features that they find useful. Mobiab was available free of charge on Google Play Store from mid-2014 until 2019. No targeted recruitment was performed to attract users.

Results

More than 500 users from the Czech Republic downloaded and signed up for the mobile app. Approximately 80% of the users used Mobiab for less than 1 week. The rest of the users used it for a longer time and 8 of the users produced data that were suitable for long-term analysis. Additionally, one of the 8 users provided their medical records, which were compared with the gathered data, and the improvements in their glucose levels and overall metabolic stability were consistent with the way in which the mobile app was used.

Conclusions

The results of this study showed that the usability of a DM-centered self-management smartphone mobile app and server-based systems could be satisfactory and promising. Nonetheless, some better ways of motivating people with diabetes toward participation in self-management are needed. Further studies involving a larger number of participants are warranted to assess the effect on long-term diabetes management.

A REVIEW ON THE DEVELOPMENT OF FAVIPRAVIR AGAINST SARS COV 2 INFECTION
Authors: B. VINOD
Published: March 2022

Covid 19, the disease first identified in the Chine city of Wuhan in December 2019 had been declared as a pandemic by WHO. This pandemic caused by Sars Cov 2 has resulted in 165.5 million infections and 3.5 million deaths globally, as of now. Till now no drug isavailable to fight against this deadly disease. The strategy adopted by drug discovery groups is drug repurposing which has not met much success with chloroquine as well as remdesivir. A relatively new candidate in the fray is favipravir which was originally developed by Toyama chemical company against influenza strains. Few synthetic routes are developed for this compound and the safety concerns are relatively few. If favourable results from the ongoing clinicaltrials arise, that may provide the therapeutic community a lethalweapon against the virus.

The spread of fire from an open car park on the ground floor of a residential building
Authors: Khasanov I. R. , Zuev S. A. , Abashkin A. A. , Zuevа A. S.
Published: March 2022

Introduction. The problem of car parks and parking spaces is relevant in many large cities, and it requiresthe optimization of parking spaces. The arrangement of open car parks on the ground floors of apartment buil­dings is an effective way to organize car parks in a house in addition to covered parking lots. In this regard, in order to assess the fire hazard of such a design solution, it is necessary to study the spreadability of fire from an open ground floor parking lot to upper floors and develop reasonable proposals for the development of new and optimization of effective fire safety requirements.

Goals and objectives. The goal of this work is to study the spread of fire hazards using the field modeling of the car burning process in an open parking lot on the ground floor of an apartment building and to assess the possibility of the fire safe arrangement of such parking lots in residential buildings.

Method. To achieve the purpose of the study, the field (CFD) modeling of the fire development pattern was performed using FDS computer software. In the course of modeling, the authors analyzed the spread of the fire hazard from an open parking lot, located on the ground floor, to the upper floors of a residential building.

Results and discussion. Temperature distributions, smoke and heat flows at various points in time were obtained as a result of modeling the development of fire in a parking lot. The results of calculations allowed to evaluate the effectiveness of various types of fire barriers and determine their parameters to meet the condition of the non-proliferation of fire. The most optimal solution is a non-combustible visor made of fire-resistant materials and installed above the opening leading to a parking lot. Given the results of the work, a set of necessary fire-figh­ting actions are proposed to ensure the possibility of arranging open parking lots in residential apartment buildings.

Conclusions. It is shown that the fire safety of residential apartment buildings that have open single-level parking lots is achievable in case of the use of fire-resistant bearing and enclosing building structures, non-combustible materials for cladding, finishing the facade of a building, as well as in the case of making a canopy, a balcony or a gallery above the opening that leads to the parking lot.

An Epistemological Appraisal of Walton’s Argument Schemes
Authors: Lumer Christoph
Published: March 2022

The article critically discusses Walton’s (and co-authors’) argument scheme approach to good argumentation. Four characteristics of Walton’s approach are presented: 1. Argument schemes provide normative requirements. 2. These schemata are enthymematic. 3. There are associated critical questions. 4. The method is inductive, abstracting schemata from groups of similar arguments. Four adequacy conditions are applied to these characteristics: AC1: effectiveness in achieving the epistemic goal of obtaining and communicating justified acceptable opinions; AC2: completeness in capturing the good argument types; AC3: efficiency in achieving the goals; AC4: justification of the argument schemes. The discussion reveals weaknesses in Walton’s account, including they are neither effective nor truly justified. A better alternative is an epistemological approach based on epistemological principles.

Published: March 2022

A inclusão das lentes de gênero nas relações internacionais contribui para a elucidação não só de lacunas existentes na elaboração das políticas em âmbito global, bem como para indicar a atuação e articulação de mulheres em torno dos temas que impactam diretamente suas vidas cotidianas. Esta análise se desenvolve no intuito de indicar as capacidades políticas e materiais articuladas por mulheres e coletivos feministas no processo de elaboração e negociação do Acordo de Paz colombiano. Para tanto, assumiu-se a importância da pluralidade de atores envolvidos na política externa, apara além dos Estados, como forma de incidir positivamente na elaboração das agendas. A partir do trabalho de Vargas-Alzate (2014), foram analisados os processos de representação do problema, elaboração da agenda, processo de tomada de decisão, implementação e avaliação do Acordo, de modo a identificar as contribuições diretas e a Cooperação Internacional das mulheres para a integração da agenda de gênero no texto final, aprovado em 2016. Concluindo que, os coletivos de mulheres de base e ex-combatentes das FARC atuaram de forma direta na formulação da agenda de gênero no Acordo Final, em Cooperação com agências multilaterais e Estados com experiência no tema internacionalmente.
TINJAUAN FIQH MUAMALAH TERHADAP PRAKTIK TABUNGAN SELASANAN (Studi Kasus Di Desa Bekonang, Kecamatan Mojolaban)
Authors: Kuswandari Nandia Arna
Published: March 2022

Penelitian ini berangkat dari fenomena praktik tabungan Selasanan dimana anggota menabung setiap hari selasa, kemudian tabungan tersebut dikelola oleh pengurus untuk dipinjamkan kepada anggota maupun luar anggota dengan penambahan manfaat sebesar 3% setiap bulan. Penulis tertarik untuk meneliti tabungan ini dengan tinjauan Islam, karena menurut wawancara dengan pengurus semua anggota dalam tabungan ini adalah beragama Islam. Mereka menabung untuk pemenuhan hari raya. Sebagaimana yang kita ketahui, sebagai umat beragama Islam harus bermuamalah sesuai dengan syariat Islam. Dari uraian di atas maka masalah yang dapat dirumusan dalam skripsi ini adalah bagaimana praktik tabungan Selasanan di Desa Bekonang, Kecamatan Mojolaban dan bagaimana praktik tabungan Selasanan ditinjau dari Fiqh muamalah.Penelitian ini termasuk jenis penelitian lapangan (field research) dengan pendekatan kualitatif tentang Fiqih Muamalah dan praktik tabungan selasanan. Sumbernya didapat dari data primer dan sekunder. Teknik pengumpulan data dengan wawancara, dokumentasi kemudian dianalisis dengan teks yang bersifat narasi lalu ditarik kesimpulan.Praktik tabungan Selasanan ini konsepnya seperti akad mudharabah, namun untuk prosentase bagi hasil tidak jelas. Hal ini menyebabkan akad ini menjadi fasidÂ  dalam praktiknya, pinjaman yang ada di tabungan Selasanan Desa Bekonang masih terdapat penambahan manfaat sebesar 3% setiap bulan. Hasil penelitian menunjukkan bahwa tambahan manfaat sebesar 3% bukan termasuk riba, namun penambahan 3%Â  setiap bulan tersebut untuk anggota sebagai pemilik dana dan sebagai ujrah bagi pengurus karena telah mengelola dana tabungan ini.

Penelitian ini bertujuan untuk menjelaskan praktik sewa menyewa indekos dikawasan kampus IAIN Surakarta pada masa pandemi Covid-19 dan menjelaskan perspektif akad ijÄrah praktik sewa menyewa indekos di kawasan kampus IAIN Surakarta pada masa pandemi Covid-19. Penelitian ini menggunakan jenis penelitian lapangan (filed research) bahwa dalam penelitian ini dilakukan secara langsung di lapangan. Sumber data didapat dari data primer berupa hasil wawancara dengan pemilik dan penyewa indekos serta data sekunder yaitu berupa buku-buku, peraturan-peraturan yang seluruhnya berkaitan dengan permasalahan yang diteliti. Metode yang digunakan studi kasus karena terjadi di lingkungan masyarakat serta fokus pada kasus tertentu untuk diamati dan dianalisis lebih mendalam. Hasil dari penelitian ini, praktik sewa menyewa sudah sesuai dengan akad ijÄrah karena adanya kedua belah pihak berakad, upah sewa, barang, dan manfaat atas barang yang disewakan. Namun, pada masa pandemi Covid-19 hak manfaat penyewa tidak sepenuhnya didapati karena force majeure atau darurat membuat penyewa tidak menempati indekos. Kewajiban penyewa pada masa pandemi Covid-19 tetap dilaksanakan dengan membayar ujroh indekos, hal tersebut membuat penyewa merasa kecewa karena tidak menempati indekos tetapi tetap diminta untuk membayar ujroh secara penuh. Kekecewaan penyewa atas ujroh pada masa pandemi tidak membatalkan akad. Dalam keadaan sulit karena Covid-19 sebenarnya penyewa dapat kelonggaran, karena keadaan penyewa bukan hal yang disengaja. Dan dalam akad ijÄrah kelonggaran bagi penyewa yakni khiyar atau memutuskan akad.

Objetivo: determinar la tasa de detección de los adenomas (TDA) e identificar las indicaciones de colonoscopia que predicen su hallazgo.

Materiales y métodos: estudio de corte transversal. Se incluyeron pacientes mayores de 18 años sometidos a colonoscopia entre febrero y julio de 2020 en un centro especializado de Medellín, Colombia. Se estimó la TDA y se identificaron las indicaciones de colonoscopia, que se consideran predictores para el hallazgo de adenomas.

Resultados: la detección general de adenomas fue del 21 % (n = 992) y la TDA en la población de tamizaje fue del 25 %. El rango de 40 a 49 años aportó el 12 % del total de adenomas detectados y la población masculina tuvo mayor incidencia (OR 1,73; IC 95 % 1,25-2,38; p < 0,001). El antecedente personal de pólipos (OR 1,86; IC 95 % 1,25-2,78; p = 0,002) y la presencia de sangre oculta en heces (OR 2,67; IC 95 % 1,12-6,35; p 0,026) se consideran predictores para el hallazgo de adenomas. El uso de filtros LCI mostró mejores resultados en la detección de las lesiones (OR 1,43; IC 95 % 1,02-2,0).

Conclusiones: las indicaciones de la colonoscopia pueden predecir la probabilidad de detección de adenomas. El género masculino, el antecedente personal de pólipos, la presencia de sangre oculta en heces y la búsqueda de adenomas a partir de los 40 años son las variables que aumentan la probabilidad de encontrar adenomas. El uso de filtros LCI aumenta la detección de lesiones. La edad sugerida para el inicio del tamizaje de CCR es a partir de los 40 años.

Background: The changes in ventricular repolarization after
cardiac resynchronization therapy (CRT) are poorly understood.
Objective: Address this knowledge gap using a multimodality
approach including electrocardiographic and echocardiographic
measurements in patients and using patient-specific computational
modeling. Methods: In 33 patients electrocardiographic and
echocardiographic measurements were performed before and at various
intervals after CRT, both during CRT-ON and temporary CRT-OFF. T-wave
area was calculated from vectorcardiograms, reconstructed from the
12-lead ECG. Computer simulations were performed using a
patient-specific eikonal model of cardiac activation with spatially
varying action potential duration (APD) and repolarization rate, fit to
a patient’s ECG. Results: During CRT-ON T-wave area diminished
within a day and remained stable thereafter, whereas QT-interval did not
change significantly. During CRT-OFF T-wave area doubled within 5 days
of CRT, while QT-interval and peak-to-end T-wave interval hardly
changed. Left ventricular (LV) ejection fraction did not significantly
increase before 1 month of CRT. Computer simulations indicated that the
increase in T-wave area during CRT-OFF can be explained by changes in
APD following chronic CRT that are opposite to the change in CRT-induced
activation time. These APD changes were associated with a reduction in
LV dispersion in repolarization during chronic CRT. Conclusions:
T-wave area during CRT-OFF is a sensitive marker for adaptations in
ventricular repolarization during chronic CRT that may include a
reduction in LV dispersion of repolarization.

monitoring. To maximize eDNA detection probabilities of sparsely
distributed populations, water samples are usually concentrated from
larger volumes and filtered using fine-pore membranes, often a
significant cost-time bottleneck in the workflow. This study aimed to
streamline eDNA sampling by investigating plankton net versus bucket
sampling, direct versus sequential filtration including self-preserving
filters. Biodiversity was assessed using metabarcoding of the small
ribosomal subunit (18S rRNA) and mitochondrial cytochrome c oxidase I
(COI) genes. Multi-species detection probabilities were estimated for
each workflow using a probabilistic occupancy modelling approach.
Significant workflow-related differences in biodiversity metrics were
reported. Highest amplicon sequence variant (ASV) richness was attained
by the bucket sampling combined with self-preserving filters, comprising
a large portion of micro-plankton. Less diversity but more metazoan taxa
were captured in the net samples combined with 5 µm pore size filters.
Pre-filtered 1.2 µm samples yielded few or no unique ASVs. The highest
average (~32%) metazoan detection probabilities in the
5 µm pore size net samples confirmed the effectiveness of
pre-concentrating plankton for biodiversity screening. These results
contribute to streamlining eDNA sampling protocols for uptake and
implementation in marine biodiversity research and surveillance.
Analysis of superposition effect of land subsidence and sea level rise in Tianjin coastal area and its emerging risks

Tianjin, as a major coastal city in China, many economic construction
planning parks and engineering construction projects have relied on the
special advantages of it. The relative sea level has brought huge hidden
danger to the economic and social development of Tianjin. And, land
subsidence is the most important factor that influences relative sea
level rise. Research analyzed Radarsat-2(2012-2016) and
Sentinel-1(2016-2018) through PS-InSAR. And the results indicated that
the subsidence rate of the southern plain of Tianjin slowed down as a
whole, however, the annual average maximum subsidence rate was still
more than 100mm/a. In addition, Wuqing and Jinghai sedimentary areas as
well as several subsidence centers have been formed, and the settlement
scope tends to expand to the east coast. By establishing a regular grid
of land subsidence and groundwater to construct a geo-weighted
regression model (GWR), it is found that Wuqing sedimentary area as a
whole is positively correlated with TCA. While for Jinghai sedimentary
area, there is a spatial difference in terms of TCA and SCA. According
to the relative sea level change, it can be predicted that the natural
coastline of Tianjin will recede by about 28 km in 5
years and 87 km in 20 years. Based on the above
research results, this paper integrates land subsidence, groundwater,
land classification status and other related factors, and uses machine
learning method (XGBoost) to evaluate Tianjin’s urban safety as well as
analyze high-risk areas and main contributing factors. From the
perspective of earth system science, this paper analyzes the potential
risks of seawater inundation and urban security caused by the
superposition of sea level rise and coastal plain land subsidence, so as
to improve the ability of coastal areas to resist disasters.

Host-specialist parasites of endangered large vertebrates are in many
cases more endangered than their hosts. In particular, low population
densities and reduced among-host transmission rates are expected to lead
to inbreeding within parasite infrapopulations living on single host
individuals. Furthermore, spatial population structures of
directly-transmitted parasites should be concordant with those of their
hosts. Using population genomic approaches, we investigated inbreeding
and population structure in a host-specialist seal louse
(Echinophthirius horridus) infesting the Saimaa ringed seal (Phoca
hispida saimensis), which is endemic to Lake Saimaa in Finland, and is
one of the most endangered pinnipeds in the world. We conducted genome
resequencing of pairs of lice collected from 18 individual Saimaa ringed
seals throughout the Lake Saimaa complex. Our analyses showed high
genetic similarity and inbreeding between lice inhabiting the same
individual seal host, indicating low among-host transmission rates.
Across the lake, genetic differentiation among individual lice was
correlated with their geographic distance, and assignment analyses
revealed a marked break in the genetic variation of the lice in the
middle of the lake, indicating substantial population structure. These
findings indicate that movements of Saimaa ringed seals across the main
breeding areas of the fragmented Lake Saimaa complex may in fact be more
restricted than suggested by previous population-genetic analyses of the
seals themselves.

Las unidades de hospitalización a domicilio (HAD) realizan cuidados complejos de nivel hospitalario a los pacientes que están en casa. Uno de los criterios esenciales para ser admitido en este servicio es tener la posibilidad de comunicarse con el equipo de HAD por teléfono para que el paciente y el cuidador puedan estar en contacto permanente con dicho equipo de atención multidisciplinar domiciliaria. Este criterio de inclusión, sin embargo, implica un impacto en la organización de las Unidades de HAD que responden a estas demandas ya que puede representar, a veces, cambios en la organización de los circuitos, visitas extraordinarias de urgencia ... etc.
El asesoramiento telefónico facilita información y capacitación para el empoderamiento del paciente y del cuidador.
Este estudio tiene como objetivo recopilar y examinar prospectivamente el impacto que estas llamadas tienen en el desarrollo del trabajo del equipo HAD, así como evaluar las razones que los generan para trabajar en la línea de la mejora continua.
A Review of Bias and Discrimination In Digital Platforms

Published: March 2022

Digital bias and discrimination have become major concerns around the world, prompting developed and developing countries to set up a legal framework to address the issues; recent articles revealed that Nigeria took a step in this establishment. Users of digital platforms are treated unfairly, unethically, and partially discriminated against based on personal data that is automatically processed by an algorithm. This study used a mixed methods research design. This included conducting a literature search, conducting a systematic literature review by assessing the literature, and analyzing studies on digital discrimination. Digital discrimination often replicates offline discrimination, either by inheriting the biases of previous decision makers or simply reflecting societal prejudices. It may also worsen existing inequalities by giving less weight to historically disadvantaged groups. This review examines this difficult problem, existing solutions, and their limitations from a legal and computer science standpoint. An empirical Study of Apparent Gender-Based Discrimination in the Display of STEM Career Ads is featured in the review to highlight algorithmic bias. It concludes with a road map of outstanding issues for mitigating these constraints. Keywords: Digital Discrimination, algorithmic bias, Machine Learning, AI, Online advertisement

Published: March 2022

The project focus on design of parking lot in school of Engineering, the parking lot design objective is to maximize the total number of parking spaces available with the considerations that the design should allow for appropriate landscaping of the parking areas without conflicting with lighting. The rapid development of available land in Auchi polytechnic, Auchi has produced large increase in land usage, to the extent that the use of large areas of land for parking cars in the school is uneconomical. It is obvious therefore, that optimum use of the available space in the school for effective space management for car storage during office hours can only be achieved through the use of good parking lot design. The peculiarity of school of Engineering in terms of shortage of space for expansion purposes cannot be overlooked, hence the disorderliness in terms of traffic parking.

Fusarium avenaceum (Fr.) Sacc. is an important phytopathogen. Fight against F. avenaceum includes primarily fungicide usage. However, novel strategies are needed in a struggle with F. avenaceum. In this study, terpinolene was used against F. avenaceum as an antimicrobial agent, and the harmlessness of terpinolene was tested on two contrast barley genotypes, Hordeum vulgare L. cv. Cervoise and H. vulgare L. cv. Premium. Firstly, minimum inhibitory concentration (MIC) and half inhibitory concentration (IC50) were detected as 6 and 3 µg µL-1. Quantitative real-time polymerase chain reaction (qRT-PCR) assay was informative about the effects of terpinolene on enniatin and zearalenone biosynthesis in F. avenaceum. Terpinolene leads to the potential decreased enniatin and zearalenone biosynthesis in F. avenaceum. However, no significant differences were recorded for gene expression of aurofusariun biosynthesis. In barley, electroconductivity (EC), catalase (CAT) activity, coupled restriction enzyme digestion-random amplification (CRED-RA), and qRT-PCR assays were tested. No significant ion leakage differences (p>0.05) were detected. Similarly, CAT activity and water loss rate (WLR) values in barley sets were not affected (p>0.05) by terpinolene treatment in majority of experiment sets. Relatively low levels of genomic template instability (75-85%) and epigenetics changes (11-20.6%) were recorded in barley due to terpinolene treatment. WRKY6, WRKY24, and WRKY41 expressions were not significantly changed. The findings showed that terpinolene could be accepted as a potential plant protective agent against phytopathogenic fungi.

Published: March 2022

The presence of supernumerary teeth is one of the most common factors that can alter the normal eruption pattern. We present here a rare phenomenon of four, molariform mesiodentes in a systemically healthy, non-syndromic patient, with non-contributory family history, causing delayed eruption of permanent, upper, central incisors. Multiple supernumerary teeth can be an important component of distinctive disorders and a valuable clue for their early diagnosis. However, this case highlights the importance of non-hereditary factors in the pathogenesis of multiple supernumerary teeth in a non-syndromic patient.

Published: March 2022

Medication-related osteonecrosis of the jaw (MRONJ) is a serious side effect of bisphosphonates, denosumab, and antiangiogenic drugs. Although the literature is rich with research work discussing MRONJ, the pathogenesis of this devastating condition has not been adequately understood yet. Roles of infection, immunity and genetic predisposition have been extremely unclear. Moreover, many controversies have been governing risk assessment and management guidelines. In 2003, 36 cases of osteonecrosis of the jaw (ONJ) associated with the use of either pamidronate or zoledronate were reported. Furthermore, in 2014, the American Association of Oral and Maxillofacial Surgeons (AAOMS) suggested the term “medication-related osteonecrosis of the jaw” (MRONJ) to describe jaw osteonecrosis related to the use of medications. This review sheds the light on recent research work discussing the pathogenesis of MRONJ. Moreover, it suggests possible guidelines for risk assessment and management based on information gathered from different research papers found in the literature.
