Procedury stosowane u noworodka donoszonego w oparciu o standard organizacyjny opieki okołoporodowej
Authors: Kęska Emilia , Kochman Dorota
Published: January 2023

Wstęp. Noworodek donoszony zarówno zaraz po urodzeniu, jak i również podczas swojego krótkiego pobytu w szpitalu na oddziale Neonatologii musi mieć wykonanych wiele procedur medycznych. Procedury te znajdują uzasadnienie w wielu aktach prawnych. Poszczególne procedury są doprecyzowywane przez rekomendacje różnych towarzystw naukowych. Personel medyczny, który je wykonuje musi świadczyć usługę najwyższej jakości. Środowisko szpitalne dla matki i noworodka zawsze będzie obcym i nie do końca akceptowalnym. Personel medyczny przez wysoką jakość opieki powinien sprawić, żeby matka ze swoim dzieckiem czuła się tam bezpiecznie i miała zaufanie do bezpiecznego stosowania wszystkich procedur u noworodka.Cel. Celem pracy jest analiza realizacji procedur medycznych w ramach standardu organizacyjnego opieki okołoporodowej wobec noworodka donoszonego.Materiały i metody. Materiał badawczy obejmuje 102 osoby-kobiety, które są matkami noworodków donoszonych urodzonych w WSS we Włocławku, w oddziale Położniczo Neonatologicznym. W pracy wykorzystano autorski kwestionariusz ankiety niezbędny do przeprowadzenia badań, skalę Apgar oraz arkusz danych o noworodku.Wyniki. Większość procedur takich, jak: odpępnienie, ocena w skali Apgar, oznakowanie, testy słuchu, testy suchej bibuły, test pulsoksymetryczny, kangurowanie, ocena stanów przejściowych, pomiary antropometryczne wykonana został u wszystkich dzieci. W najmniejszym stopniu wykonano testy: odśluzowanie – 29 osób (28,4%), odruchy – 4 osoby (3,9%) oraz HBS – 1 osoba (1,0%). Wiek badanych, nie pozostawał w istotnej statystycznie korelacji z wynikami wykonywanych procedur (p>0,05). Ze względu na poziom istotności (p>0,05),nie odnotowano istotnych statystycznie różnic pomiędzy grupami miejsca zamieszkania dotyczących wykonania procedur.Wnioski. Zdecydowana większość procedur medycznych w oparciu o standard organizacyjny opieki okołoporodowej wykonano u wszystkich dzieci, świadcząc przez personel medyczny usługę o najwyższej jakości. Matki w większości nie posiadają wiedzy na temat procedur okołoporodowych sosowanych u ich dzieci. Największe zapotrzebowanie na edukację dotyczących procedur medycznych u noworodka mają kobiety z niższym wykształceniem i pierwiastki.
Features of photoluminescence of oxygen-saturated films of methoxypolyphenylene vinylene (MEH-PPV)
Authors: Kucherenko M.G.  , Penkov S. A.
Published: January 2023

The effects of the influence of the magnetic field on the luminescence intensity of methoxypolyphenylene vinylene (MEH-PPV) films at various air pressures above the samples are investigated. An inversion of the sign of the magnetic field effect was detected with a smooth change in the oxygen concentration in the system. Based on the balance equations, a theoretical model of processes is proposed that takes into account the formation of populations of triplet (T) excitons of MEH-PPV and singlet oxygen during the reactions of triplet-triplet annihilation, T-3Sigmag(O2)-quenching and T-1Deltag(O2)-cross-annihilation of electronic excitations. According to the proposed theoretical model, the magnetic field effects of delayed fluorescence at different concentrations of O2 molecules in MEH-PPV films are calculated, consistent with the experimental results. Keywords: triplet excitons, π-conjugated polymers, magnetically dependent fluorescence, singlet oxygen.

Published: January 2023

To explain the experimentally observed effect of silver nanoparticles on the fluorescence of organic dyes and the nonradiative intermolecular transfer of electronic excitation energy in multilayer nanostructures, the previously proposed theoretical model of plasmon resonance in spherical nanoparticles of metals was used. The rates of radiative and nonradiative (FRET) processes in film structures with Ag nanoparticles were calculated for fluorescein and rhodamine B molecules, as well as for two-component systems fluorescein-nile red (NR) and rhodamine B-NR. A version of the model was used that takes into account the effect of NPs on FRET between molecules, the radiative decay of donor and acceptor molecules, and the energy transfer from the dye to plasmonic nanoparticles. The calculation of the UDA rate for pairs with different energy transfer efficiency showed a greater increase in the UDA parameter for the fluorescein-nile red pair than for the rhodamine B-nile red pair. Estimation of the fluorescence enhancement factor of donor and energy acceptor molecules and the rate of energy transfer from the dye to silver NPs showed their insignificant contribution to the formation of the resulting energy transfer efficiency enhancement in the presence of plasmonic NPs. Keywords: energy transfer, silver nanoparticles, plasmon, model

The kinetics of photooxidation of tetrahydrobiopterin was investigated, the quantum yields of the formation of dihydropterin dimers were calculated when using a xenon lamp, a tunable UV laser and a UV LED as UV radiation sources. A comparative analysis of the effectiveness of these sources for the photooxidation process of tetrahydrobiopterin allowed us to conclude that the most effective for the purposes of vitiligo phototherapy are, apparently, UV LED sources with emission maxima in the region of 325 nm. Keywords: vitiligo, tetrahydrobiopterin, melanin, oxidative stress, H2O2, UVB vitiligo phototherapy.
The Success of Cancer Crowdfunding Campaigns: Project and Text Analysis
Authors: Zhang Xupin , Tao Xinqi , Ji Bingxiang , Wang Renwu , Sörensen Silvia
Published: January 2023

Background

Recent studies have analyzed the factors that contribute to variations in the success of crowdfunding campaigns for a specific cancer type; however, little is known about the influential factors among crowdfunding campaigns for multiple cancers.

Objective

The purpose of this study was to examine the relationship between project features and the success of cancer crowdfunding campaigns and to determine whether text features affect campaign success for various cancers.

Methods

Using cancer-related crowdfunding projects on the GoFundMe website, we transformed textual descriptions from the campaigns into structured data using natural language processing techniques. Next, we used penalized logistic regression and correlation analyses to examine the influence of project and text features on fundraising project outcomes. Finally, we examined the influence of campaign description sentiment on crowdfunding success using Linguistic Inquiry and Word Count software.

Results

Campaigns were significantly more likely to be successful if they featured a lower target amount (Goal amount, β=−1.949, z score=−82.767, P<.001) for fundraising, a higher number of previous donations, agency (vs individual) organizers, project pages containing updates, and project pages containing comments from readers. The results revealed an inverted U-shaped relationship between the length of the text and the amount of funds raised. In addition, more spelling mistakes negatively affected the funds raised (Number of spelling errors, β=−1.068, z score=−38.79, P<.001).

Conclusions

Difficult-to-treat cancers and high-mortality cancers tend to trigger empathy from potential donors, which increases the funds raised. Gender differences were observed in the effects of emotional words in the text on the amount of funds raised. For cancers that typically occur in women, links between emotional words used and the amount of funds raised were weaker than for cancers typically occurring among men.

Published: January 2023

Background

Echocardiography (ECHO) is a type of ultrasonographic procedure for examining the cardiac function and morphology, with functional parameters of the left ventricle (LV), such as the ejection fraction (EF) and global longitudinal strain (GLS), being important indicators. Estimation of LV-EF and LV-GLS is performed either manually or semiautomatically by cardiologists and requires a nonnegligible amount of time, while estimation accuracy depends on scan quality and the clinician’s experience in ECHO, leading to considerable measurement variability.

Objective

The aim of this study is to externally validate the clinical performance of a trained artificial intelligence (AI)–based tool that automatically estimates LV-EF and LV-GLS from transthoracic ECHO scans and to produce preliminary evidence regarding its utility.

Methods

This is a prospective cohort study conducted in 2 phases. ECHO scans will be collected from 120 participants referred for ECHO examination based on routine clinical practice in the Hippokration General Hospital, Thessaloniki, Greece. During the first phase, 60 scans will be processed by 15 cardiologists of different experience levels and the AI-based tool to determine whether the latter is noninferior in LV-EF and LV-GLS estimation accuracy (primary outcomes) compared to cardiologists. Secondary outcomes include the time required for estimation and Bland-Altman plots and intraclass correlation coefficients to assess measurement reliability for both the AI and cardiologists. In the second phase, the rest of the scans will be examined by the same cardiologists with and without the AI-based tool to primarily evaluate whether the combination of the cardiologist and the tool is superior in terms of correctness of LV function diagnosis (normal or abnormal) to the cardiologist’s routine examination practice, accounting for the cardiologist’s level of ECHO experience. Secondary outcomes include time to diagnosis and the system usability scale score. Reference LV-EF and LV-GLS measurements and LV function diagnoses will be provided by a panel of 3 expert cardiologists.

Results

Recruitment started in September 2022, and data collection is ongoing. The results of the first phase are expected to be available by summer 2023, while the study will conclude in May 2024, with the end of the second phase.

Conclusions

This study will provide external evidence regarding the clinical performance and utility of the AI-based tool based on prospectively collected ECHO scans in the routine clinical setting, thus reflecting real-world clinical scenarios. The study protocol may be useful to investigators conducting similar research.

Published: January 2023

Abstract: Each individual has a distinctive signature that is primarily used for personal identification and the confirmation of significant papers orlegal transactions. Static (offline) and dynamic signature verification come in two flavours (online). After a signature has been made, it can be verified using a methodknown as static verification. For a lot of documents, off line signature verification is ineffective and slow. Online biometric personal verification, such as fingerprints, eye scans, etc., has increased in recent years as a way to get over the limitations of offline signature verification. Convolution neural network (CNN)-based offline signature verification is proposed inthis study. We can extract more accurate representations of the image content using a neural network model called CNN. In order to improve categorization, CNN starts with the raw pixel datafrom the image, trains the model, and then automatically extracts the features. CNN's key advantage over its forerunners is that it automatically identifies significant features without human supervision and that it predicts images with the highest degree of accuracy of any algorithm.

Review: Advances in Lung Cancer Research
Authors: Gavhane Santosh Bhagwan
Published: January 2023

Abstract: Lung cancer is one of the most leading causes of cancer death in the world. Lung cancer also known as lung carcinoma is a malignant lung tumor characterized by uncontrolled cell growth in tissues of the lung. If left untreated this growth can spread beyond the lung by process of metastasis into nearby tissue or other parts of the body. Most cancers that start in the lung known as primary lung cancers are carcinomas that derive from epithelial cells. The main primary types are smallcell lung carcinoma (SCLC) and non-small-cell lung carcinoma (NSCLC). The vast majority (85%) of cases of lung cancer are due to long-term exposure to tobacco smoke. About 10–15% of cases occur in people who have never smoked. These cases are often caused by a combination of genetic factors and exposure to radon gas, asbestos, or other forms of air pollution, including second-hand smoke. This review gives a detailed idea on the epidemiology, causes, types, signs & symptoms, and treatment of lung cancer.
Fracture mechanics and its application in the fatigue behavior of reinforced welded hand-holes in aluminum light poles
Authors: Rusnak Cameron R. , Menzemer Craig
Published: January 2023

Fracture mechanics can be defined as a methodology that is used to
predict and diagnose failure of a part with some kind of existing crack
or flaw. These models can be used to aid in the examination of
laboratory experiments and possibly give an explanation into its fatigue
life. This study utilized AFGROW as the fracture mechanics software. All
models were used on a previous study conducted on aluminum light poles
containing hand-holes and reinforcement (when applicable). The ultimate
goal of this study was an attempt to replicate the laboratory results
from these previous studies and to gain a deeper understanding of the
failure modality. In total, eight fracture mechanics models were created
to achieve this goal. Of these models, three contained an initial break,
two had a beta correction added, one contained an open hole, and two
were modeled as a plate. From all of the fracture mechanics models,
models containing plates yielded the best results when it came to
replicating lab results. Some finite element analysis (FEA) in ABAQUS
was used in conjunction with the fracture mechanics models.
Chromosome-level genome assembly and population genomic analysis provide novel insights into the immunity and evolution of Sogatella furcifera

Published: January 2023

Sogatella furcifera is an agricultural pest of great concern in
China and Southeast Asian countries. However, the lack of accurate and
complete reference genome resources has hindered the understanding of
immunity and evolution of S. furcifera. Here, we utilized
Nanopore sequencing to generate a chromosome-level assembly and
annotation of the S. furcifera genome (0.64 Gb), with a GC
content of 34.25%. This genome comprised 15 chromosomes covering
95.04% of the estimated genome size, together with an additional 624
small scaffolds making up the remaining 4.96% of the genome of S.
furcifera. A total of 24,669 protein-coding genes as well as 1211 long
noncoding RNA and 7595 circular RNA transcripts were well annotated and
predicted. Comparative genomic analysis revealed the rapidly evolved
genes associated with multiple immune-related pathways in S.
furcifera, which may be responsible for its rapid evolutionary
adaptation. In addition, 14 immune genes in the classic immune pathways
were selected for functional validation through RNA interference
experiments, demonstrating the antiviral effects of Dorsal and Dif genes
in S. furcifera. Genome resequencing of 44 individuals from 12
geographic populations revealed an absence of population structures and
frequent gene flow among all populations. Sweep analysis indicated that
2926 genes were under natural selection and significantly enriched in
several biological processes of morphogenesis and immunity. The first
systematic identification of immune genes and noncoding RNAs from
chromosome-level genome assembly plus the comparative and population
genomic analysis will provide more insights into the understanding of
the immunity and evolutionary adaptation of S. furcifera.
Calculation of the solid fat content of vegetable fats using the Hildebrand equation
Authors: Schaink Hermanus
Published: January 2023

Vegetable fats are complex multi-component mixtures of triglycerides.
Here, the solidification behavior of a few vegetable fats is calculated
using the Hildebrand equation. This calculation assumes, in the liquid
phase, ideal mixing of the different components, in combination with
literature data about the temperatures and enthalpies of fusion of the
individual triglycerides. It further assumes a decomposition of the
triglyceride blend into binary blends dissolved in an inert solvent. The
solid fat content is calculated as function of the temperature, assuming
that all triglycerides solidify in a single crystal habit (all α or all
β or all β’). The minor triglyceride components are explicitly taken
into account. The calculated solid fat contents for cocoa butter, palm
oil, inter-esterified palm oil and palm kernel olein oil are compared to
pNMR data, reported in the literature. Temperature ranges are found, in
which specific crystal modifications match to the pNMR data for the
solid fat content. These temperature ranges are found to be consistent
with literature data obtained using X-ray diffraction. As a by-product,
the calculation presented here, enables the construction of scenarios
that describe which triglyceride solidifies in which temperature
interval.
Fault detection and classification of VSC-HVDC transmission lines using a deep intelligent algorithm
Authors: Salehi Amir Inanloo , Ghaffarzadeh Navid , Ghashghaei Saber
Published: January 2023

Considering the sensitivity of HVDC-transmission system protection and
the difficulty in identifying high-resistance earth-faults,this paper
presents three methods for fault location and classification in VSC-HVDC
transmission lines.These methods are evaluated in terms of efficiency
and reliability.The current and voltage signals obtained from the
network are pre-processed by performing DWT,and then using feature
extraction methods,special and unique features are extracted for
different states of the signals,and then using these features and
proposed algorithms,network learning was performed to detect faults.In
addition,the effectiveness of the proposed plan has been confirmed for
different fault scenarios related to extensive changes in fault
resistance,fault starting angle and fault location.These algorithms were
also investigated in unwanted noise-conditions and the reliability of
these algorithms was confirmed.In this article methods,k nearest
neighbor(KNN),support vector machine(SVM) and deep-neural network(DNN)
have been investigated.The strength of this research is use of a new
method of extracting features from the fractal dimension,which has been
able to provide outstanding capabilities that can lead to improved
diagnosis with a small number of study data and different conditions.The
main advantages of proposed-method are higher speed and accuracy than
conventional methods.The test results show that the proposed method can
reliably and accurately identify and classify high-impedance faults.
Adoption of digital vaccination services: It is the click flow, not the value. An empirical analysis of the vaccination management of the COVID-19 pandemic in Germany.
Authors: Alscher Alexander , Schnellbächer Benedikt , Wissing Christian
Published: January 2023

This research paper examines the adoption of digital services for the
vaccination in the COVID-19 pandemic in Germany. Based on a survey in
Germany’s federal state with the highest vaccination rate, which used
digital vaccination services, its platform configuration and adoption
barriers are analyzed to understand existing and future levers for
optimizing vaccination success. Though technological adoption and
resistance models have been originally developed for consumer goods
markets, this study gives empirical evidence for the applicability of an
adjusted model explaining platform adoption for vaccination services in
special and for digital health services in general. In this model, the
configuration areas personalization, communication, and data management
have a remarkable effect to lower adoption barriers, but only functional
and psychological factors affect the adoption intention. Above all, the
usability barrier stands out with the strongest effect while the
often-cited value barrier is not significant at all. Personalization is
found to be the most important factor for managing the usability barrier
and thus for addressing the needs, preferences, situation, and
ultimately the adoption of the citizens as users. Implications are given
for policy makers and managers in such pandemic crisis to focus on the
click flow and server-to-human interaction rather than emphasizing value
messages or touching traditional factors.

Localization of deformation in a non-collisional subduction orogen: the roles of dip geometry and plate strength on the evolution of the broken Andean foreland, Sierras Pampeanas, Argentina
Authors: Pons Michaël , Piceda Constanza Rodriguez , Sobolev Stephan V. , Scheck-Wenderoth Magdalena , Strecker Manfred R.
Published: January 2023

The non-collisional subduction margin of South America is characterized
by different geometries of the subduction zone and upper-plate
tectono-magmatic provinces. The localization of deformation in the
southern Central Andes (29°S–39°S) has been attributed to numerous
factors that combine the properties of the subducting oceanic Nazca
plate and the continental South American plate. In this study, the
present-day configuration of the subducting oceanic plate and the
continental upper plate were integrated in a data-driven geodynamic
workflow to assess their role in determining strain localization within
the upper plate of the flat slab and its southward transition to a
steeper segment. The model predicts two fundamental processes that drive
deformation in the Andean orogen and its foreland: eastward propagation
of deformation in the flat-slab segment by a combined bulldozing
mechanism and pure-shear shortening that affects the broken foreland and
simple-shear shortening in the fold-and-thrust belt of the orogen above
the steep slab segment. The transition between the steep and
subhorizontal subduction segments is characterized by a 370-km-wide area
of diffuse shear, where deformation transitions from pure to simple
shear, resembling the transition from thick to thin-skinned foreland
deformation in the southern Sierras Pampeanas. This pattern is
controlled by the change in dip geometry of the Nazca plate and the
presence of mechanically weak sedimentary basins and inherited faults.
The evolution of African monsoons and its impacts on precipitation seasonality in the late Cenozoic and future climate change
Authors: Arthur Frank , Boateng Daniel , Baidu Michael , Aryee Jeffrey N A
Published: January 2023

The West African Monsoon (WAM) strongly drives precipitation variability
and seasonality across continental West Africa and the tropical Eastern
Atlantic. However, the evolution of the WAM in the late Cenozoic, in
response to changes in vegetation, atmospheric CO ,
orbital forcings, paleogeography, and orography as well as its
teleconnections such as the mean location of the African Easterly Jet
(AEJ), Tropical Easterly Jet (TEJ), SubTropical Jet (STJ),
Inter-Tropical Discontinuity (ITD) and low-level westerly flow is not
well constrained. We contribute to understanding past WAM dynamics by
performing high-resolution, time-specific paleoclimate simulation using
General Circulation Model ECHAM5. We focus our analysis on the migration
and intensification of the WAM and its associated atmospheric
thermodynamic structure which influence the rainfall seasonality and
patterns across the Sahel, Guinea Coast, and Sahara regions.
Seismotectonics of Sulawesi, Indonesia
Authors: Serhalawan Yopi , Chen Po-Fei
Published: January 2023

In eastern Indonesia, Sulawesi Island lies at the triple junction of the
Australian, Sunda, and Phillippine Sea plates. The distinctive K-shape
of Sulawesi, consisting of four arms (North, South, East, and
Southeast), resulted from continuous geological evolution at different
stages. Consequently, each arm has a different deformation style and
tectonic setting. We studied the seismotectonics of Sulawesi using the
updated dataset for earthquake seismicity and focal mechanisms,
including additional supporting data. We grouped Sulawesi shallow part
(< 60 kilometers) into six regions, while the deep part
(60-400 kilometers) related to the Celebes Sea and Sula slabs. Regarding
the shallow part, we found a lack of seismicity in the northern
Palu-Koro fault and near the center of the North Sulawesi Trench,
although these zones have high slip rates. On the deep part, the Celebes
Sea slab showed an increasing dip as depth increased, whereas the Sula
slab showed a steeply dipping slab. Moreover, the western Sula slab
indicated an absence of shallow depth earthquakes (60–230 kilometers).
Based on our investigations, we derived the following well-founded
conclusions: (1) The northern Palu-Koro fault was beyond the high
relative motion of the Makassar and North Sula blocks, resulting
inactive seismicity. (2) A seismic gap or aseismic slip from the Celebes
Sea subduction probably produced the low seismicity level near the
center of the North Sulawesi Trench. (3) The shallow inactive seismicity
in the western Sula slab might be due to the upper slab detaching during
the first stage collision in the Early Miocene.
Local beamforming and back-projection of induced earthquakes in Helsinki, southern Finland
Authors: Li Bo , Gabriel Alice-Agnes , Hillers Gregor
Published: January 2023

Seismic array processing is routinely used to infer detailed earthquake
properties of intermediate and large events, however, the source
properties of microseismicity often remain elusive. In this study, we
use high signal-to-noise ratio seismograms of 204 earthquakes induced by
the 6 km deep 2018 Espoo/Helsinki geothermal stimulation to evaluate the
capabilities of beamforming and back-projection array methods. We show
that mini array beamforming is sensitive to medium heterogeneity and
requires calibration to mitigate systematic slowness biases.A combined
and wave back-projection approach significantly improves depth
resolution, reducing offsets to catalogue locations from km to m.
Supported by numerical experiments, we demonstrate that back-projection
swimming patterns can constrain focal mechanisms. Our results imply that
back-projection of data collected over a wide azimuthal range can be
used to monitor and characterize local-scale microseismicity, whereas
beamforming calibration requires independently obtained reference
observations.
Fluidos, Perispírito e as Manifestações Espirituais
Authors: Da Fonseca Alexandre
Published: January 2023

Fluido espiritual ou, simplesmente, fluido, é um conceito central na Doutrina Espírita (DE). Toda fenomenologia espírita, desde a simples ação sobre o próprio corpo material até a mais complexa modalidade de mediunidade, envolve essa substância. Manifestação espiritual é o nome dado a um fenômeno psíquico cuja causa é espiritual. Fenômenos anímicos ou mediúnicos, de efeitos físicos ou intelectuais, são manifestações espirituais. A compreensão precisa da relação entre os fluidos e as manifestações espirituais requer aprofundamento no estudo da DE. Em particular, considerado por Kardec “um dos mais importantes produtos do fluido cósmico”, o perispírito também será abordado. Tem se tornado comum confundir o que é causa e o que é efeito nas relações entre fluidos e a matéria densa e entre fluidos e o princípio inteligente individualizado. Neste artigo, uma revisão do conceito de fluidos espirituais e seu papel nos fenômenos espíritas é apresentada com base na DE. Em vista de alguns equívocos que se tornaram comuns no meio espírita, como considera-los como sendo “energias” ou “ondas”, além de serem esclarecidos com base na DE e na Ciência, a atualidade científica do termo fluido será mostrada. Esse trabalho também abrange o papel dos fluidos nos mecanismos da mediunidade e nos mecanismos do passe, de modo totalmente coerente com a DE.

In Latvia, the employment of persons with disability is two times lower than the European Union average, which indicates a marked social and income inequality in the country, as well as the dependence of such persons on national and local government support. One of the solutions for increasing the employment of people with disability is social entrepreneurship. In Latvia, 28% of a total of 189 social enterprises are work integration social enterprises, which mostly employ persons with disability. The research aims to examine the experience of work integration social enterprises in Latvia. To achieve the aim, the research performed a case study of three work integration social enterprises. It was found that the main goal of all the enterprises was to integrate people with disability into the labour market through their training and skills development. The main challenges of employing the target group were their insufficient level of education and poor professional skills, as well as the need to adapt the working environment and equipment. Depending on the degree and kind of disability, the workloads for such persons are also adapted. National, local government and other available support instruments for social enterprises are used to expand their operation, the most important of which are the grants administered by the Ministry of Welfare and the finance institution Altum, as well as a tax credit – a lower employer mandatory state social insurance contribution rate if employing people with disability

A baixa cobertura da Estratégia de Saúde da Família (ESF) nos grandes municípios (35%) evidencia a dificuldade para se consolidar como política de saúde.  Objetivos: Identificar a situação da ESF em Sorocaba/SP e entender as dificuldades para a sua implementação e manutenção. Métodos: Pesquisa descritiva, exploratória e qualitativa. Foram avaliados dados documentais da Secretaria Municipal de Saúde (SMS) e realizadas entrevistas com 6 gestores. De 1998 a 2016 a cobertura populacional da ESF passou de 2,5% a 25,5%, aumento devido à adesão ao Programa Mais Médicos. Resultados: Os gestores apontaram como dificuldades para a implementação da ESF: falta de financiamento, pouco apoio estadual e federal, mudanças frequentes na SMS, resistência dos profissionais de saúde às políticas do SUS. Conclusões: são necessárias mudanças de conceito da gestão municipal e quebra de resistências políticas para viabilizar a ESF como modelo de Atenção Primária à Saúde em grandes municípios.
Economic Modeling in Rawls
Authors: Coker David C.
Published: January 2023

Critics of Rawls's A Theory of Justice frequently envision his original position as containing a human consciousness. Thus, the re- strictions Rawls introduces for this ‘individual’—the lack of particular circumstantial and personal information—is considered a potential problem. The very ways in which Rawls circumscribes the knowledge available in this position is thought to compromise the personhood of the individual there, and hence as well the conclusions reached (that is, Rawls’s two principles). This paper will argue that, on the contrary, the lack of full personhood is a critical part of Rawls’s modeling strategy, and that Rawls borrowed this particular sense of modeling from eco- nomics. It is well known that Rawls worked to verse himself in economic theory, and it is difficult to overlook its use in Theory. It will be argued that it is through parallels with economic reasoning that Rawls’s original position model can be most fruitfully understood.
Hair and Scalp Disease Detection using Machine Learning and Image Processing

Almost 80 million Americans suffer from hair loss due to aging, stress, medication, or genetic makeup. Hair and scalp-related diseases often go unnoticed in the beginning. Sometimes, a patient cannot differentiate between hair loss and regular hair fall. Diagnosing hair-related diseases is time-consuming as it requires professional dermatologists to perform visual and medical tests. Because of that, the overall diagnosis gets delayed, which worsens the severity of the illness. Due to the image-processing ability, neural network-based applications are used in various sectors, especially healthcare and health informatics, to predict deadly diseases like cancers and tumors. These applications assist clinicians and patients and provide an initial insight into early-stage symptoms. In this study, we used a deep learning approach that successfully predicts three main types of hair loss and scalp-related diseases: alopecia, psoriasis, and folliculitis. However, limited study in this area, unavailability of a proper dataset, and degree of variety among the images scattered over the internet made the task challenging. 150 images were obtained from various sources and then preprocessed by denoising, image equalization, enhancement, and data balancing, thereby minimizing the error rate. After feeding the processed data into the 2D convolutional neural network (CNN) model, we obtained overall training accuracy of 96.2%, with a validation accuracy of 91.1%. The precision and recall score of alopecia, psoriasis, and folliculitis are 0.895, 0.846, and 1.0, respectively. We also created a dataset of the scalp images for future prospective researchers.

As the geotechnical investigation is a challenging task due to natural heterogeneity and the limited data so the cheap surface geoelectric resistivity method is widely applied to know the complex subsurface information. To produce the electrical images for a site located at Balukhali Rohingya Refugee Camps area in Ukhiya-Teknaf, Cox’s Bazar, Bangladesh, a field data acquisition technique along with RES2DINV software has been performed. Two Wenner soundings on the 25 m and 50 m image lines at every 1 m and 2 m electrode spacing respectively reveal the shallow subsurface lithological variations. On the other hand, 34 samples were collected from two boreholes at different depths and tested under field and laboratory conditions to measure some basic geotechnical properties such as moisture content, grain size distribution, liquid limit, plastic limit, plasticity index, and specific gravity. These geotechnical parameters were compared with the constructed electrical images and confirmed the significance of the electrical resistivity values. Therefore, the geoelectrical resistivity method can be applied as an additional tool to support and enhance conventional geotechnical interpretation purposes as well as shallow landslide site characterization in Bangladesh.

Korišćenje energija iz obnovljivih izvorave više zaokupira pažnju istraživača. Potreba za redukcijom potrošnje električne enegije u oblasti klimatizacije i čuvanja hrane upućuje na sisteme u kojima se, za postizanje rashladnog efekta, koriste solarna energija ili otpadna toplota. Pored apsorpcionih i ejektorskih uređaja, značajno mesto u ovoj oblasti sve više zauzimaju i adsorpcioni rashladni sistemi. I pored toga što solarno adsorpciono hlađenje predstavlja jednu od najnovijih tehnologija solarnog hlađenja, ona u sadašnje vreme uveliko prevazilazi faze pilot ili demonstracionih instalacija. Proširenje tržišta, klimatske promene i povećana ekološka svest, pokazuju značajan potencijal za razvoj upravo ovkavih sistema. U radu je osnovna pažnja posvećena upravo solarnim adsorpcionim sistemima, principima njihovog rada i ukazivanju na određene prednosti i nedostatke.

Everyday demands for safer and more efficient therapy for many diseases, especially serious ones such as various types of cancer, put various challenges in front of modern science. One of them lies in the fact that numerous anticancer drugs are poorly-water soluble and therefore their encapsulation and controlled release are quite demanding processes. In the present study, we deepened our research of carrier based on hydrophilic poly(methacrylic acid) modified with amphiphilic casein, in which poorly water-soluble model drug caffeine was encapsulated (PMAC-Caf hydrogels). It was investigated how neutralization degree of methacrylic acid (MAA) and amount of encapsulated caffeine affected swelling behavior of the PMAC-Caf hydrogels and caffeine release. Easy, one pot, simultaneous synthesis of the carrier and the encapsulation of caffeine is presented, obtaining thereby as prepared PMAC-Caf drug delivery system that could respond to the specific demands of the targeted delivery of the poorly water-soluble drug - protecting it in the environment which simulated human stomach and releasing it in the environment which simulated human intestines. Changing the synthesis parameters (neutralization degree of MAA and/or amount of encapsulated caffeine) we achieved controlled release of caffeine, indicating that the number of the required doses of the drug in the treatment and its side effects could be reduced. Results showed that the PMAC-Caf drug delivery systems have huge potential for controlled release of poorly water-soluble drugs.

Ética y realidad económica: dilemas entre lo justo y lo legal para los contadores públicos. Discusión de algunos casos en la ciudad de Medellín
Authors: Agudelo Vélez María Alejandra , Londoño Cossío Ana María
Published: January 2023

Este articulo expone cómo los contadores públicos se encuentran inmersos entre lo justo y lo legal por el dilema que representa la ética y la situación económica del país; es así como se identifican algunas situaciones que podrían ser la causa de ese dilema, como lo es el diseño curricular de los programas. Así mismo, se evidencia desconexión entre la teoría y la práctica por la gran proliferación de normas en materia contable y tributaria que se presenta en el país, generando que los recién egresados ya estén desactualizados, además anteponer el interés particular al correcto ejercicio profesional es una de las consecuencias de la situación económica que enfrenta el país. Por su parte, la alta carga impositiva a la que son sometidas tanto las grandes como las medianas y pequeñas empresas influye en el quebrantamiento de los códigos de ética por parte del Contador Público por anteponer su propia visión de justicia ante la legalidad.
