Predict new cases of the Coronavirus 19; in Michigan, U.S.A. or other countries using Crow-AMSAA Method (Preprint)
Authors: Wang Yanshuo
Published: April 2020

BACKGROUND

Statistical predictions are useful to predict events based on statistical models. The data is useful to determine outcomes based on inputs and calculations. The Crow-AMSAA method will be explored to predict new cases of Coronavirus 19 (COVID19). This method is currently used within engineering reliability design to predict failures and evaluate the reliability growth. The author intents to use this model to predict the COVID19 cases by using daily reported data from Michigan, New York City, U.S.A and other countries.
The piece wise Crow-AMSAA (CA) model fits the data very well for the infected cases and deaths at different phases during the start of the COVID19 outbreak. The slope β of the Crow-AMSAA line indicates the speed of the transmission or death rate. The traditional epidemiological model is based on the exponential distribution, but the Crow-AMSAA is the Non Homogeneous Poisson Process (NHPP) which can be used to modeling the complex problem like COVID19, especially when the various mitigation strategies such as social distance, isolation and locking down were implemented by the government at different places.

OBJECTIVE

This paper is to use piece wise Crow-AMSAA method to fit the COVID19 confirmed cases in Michigan, New York City, U.S.A and other countries.

METHODS

piece wise Crow-AMSAA method to fit the COVID19 confirmed cases

RESULTS

From the Crow-AMSAA analysis above, at the beginning of the COVID 19, the infectious cases did not follow the Crow-AMSAA prediction line, but during the outbreak start, the confirmed cases does follow the CA line, the slope β value indicates the pace of the transmission rate or death rate in each case. The piece wise Crow-AMSAA describes the different phases of spreading. This indicates the speed of the transmission rate could change according to the government interference, social distance order or other factors. Comparing the piece wise CA β slopes (β: 1.683-- 0.834--0.092) in China and in U.S.A (β:5.138--10.48--5.259), the speed of infectious rate in U.S.A is much higher than the infectious rate in China. From the piece wise CA plots and summary table 1 of the CA slope βs, the COVID19 spreading has the different behavior at different places and countries where the government implemented the different policy to slow down the spreading.

CONCLUSIONS

From the analysis of data and conclusions from confirmed cases and deaths of COVID 19 in Michigan, New York city, U.S.A, China and other countries, the piece wise Crow-AMSAA method can be used to modeling the spreading of COVID19.

Authors: Ahmad Araz Ramazan , Murad Hersh Rasool
Published: April 2020

BACKGROUND

In the first few months of 2020, information and news reports about the coronavirus disease (COVID-19) were rapidly published and shared on social media and social networking sites. While the field of infodemiology has studied information patterns on the Web and in social media for at least 18 years, the COVID-19 pandemic has been referred to as the first social media infodemic. However, there is limited evidence about whether and how the social media infodemic has spread panic and affected the mental health of social media users.

OBJECTIVE

The aim of this study is to determine how social media affects self-reported mental health and the spread of panic about COVID-19 in the Kurdistan Region of Iraq.

METHODS

To carry out this study, an online questionnaire was prepared and conducted in Iraqi Kurdistan, and a total of 516 social media users were sampled. This study deployed a content analysis method for data analysis. Correspondingly, data were analyzed using SPSS software.

RESULTS

Participants reported that social media has a significant impact on spreading fear and panic related to the COVID-19 outbreak in Iraqi Kurdistan, with a potential negative influence on people’s mental health and psychological well-being. Facebook was the most used social media network for spreading panic about the COVID-19 outbreak in Iraq. We found a significant positive statistical correlation between self-reported social media use and the spread of panic related to COVID-19 (R=.8701). Our results showed that the majority of youths aged 18-35 years are facing psychological anxiety.

CONCLUSIONS

During lockdown, people are using social media platforms to gain information about COVID-19. The nature of the impact of social media panic among people varies depending on an individual's gender, age, and level of education. Social media has played a key role in spreading anxiety about the COVID-19 outbreak in Iraqi Kurdistan.

Malang Regency has 33 districts. Jabung sub-district is one of the regions in Malang Regency. Jabung village is located in Jabung sub-district, has a population of 9,224 people and an area of 705.78 ha. The number of family heads or families is 2564 with an average family member of 4 people per family. The Jabung Village development index is 0.656 which includes a developing classification. This means that Jabung Village is a village that has village potentials that need to be developed and need real touch and contribution.The conditions that have occurred in Jabug Village for activists in Malang masks are the lack of educational infrastructure and the lack of efforts to preserve the art of Malang masks. This is indicated by the small number of poor mask activists at a young age. Besides, the problem faced by partners in maintaining the Malangan Mask art as an art of ancestral heritage is the inclusion of Westernization culture that has engulfed Indonesia as globalization is expanding resulting in the less desirable local culture. This also had an impact on the Malangan Mask art which was increasingly abandoned by the public. And also the problem of partners is that there are no poor mask educative media to introduce mask characters to visitors, or students who want to learn mask characters.The solution to the problem that occurs in mask craftsmen is by giving lectures about the preservation of the malangan mask art is the absence of science and technology-based educational media for the community (IBM) to preserve and preserve the history of the poor art character. The outcome of the use of Science and Technology for the Community (IBM) is the creation of an e-catalog is a media catalog book in electronic form that makes it easy for everyone to read information through smartphones or other electronic media. Making the malangan mask E-catalog will contain the history and character of the mask as well as souvenir information from the malangan mask art in Jabung village. Key words: Mask Village; Jabung Village; preservatione; science and technology

EXAMINING HIGHER ORDER THINKING IN INDONESIAN LOWER SECONDARY MATHEMATICS CLASSROOMS
Authors: Tanudjaya Citra Putriarum , Doorman Michiel
Published: April 2020

Indonesian students’ poor performance in the mathematics test of PISA 2015 prompted the decision by the Ministry of Education of Indonesia to pay more attention to the integration of higher-order thinking (HOT) in the curricula starting in 2018. This new regulation emphasizes the need to have a shared understanding of HOT in mathematics on many levels, such as curriculum, pedagogy, and assessment, and among students, teachers and policy makers. This study aims to examine HOT in Indonesian lower secondary mathematics classrooms by assessing students’ ability to demonstrate HOT skills through an open-ended mathematics problem, and by exploring teachers’ views of HOT skills through semi-structured interviews. It involved 372 ninth-grade students and six mathematics teachers from six lower secondary schools in Jakarta and Palembang. The findings show that most students could construct the mathematical model but experienced difficulty in transferring knowledge into new contexts, in applying creative thinking, and with information literacy skills. Besides, some of the teachers were familiar with the concept of HOT, but some viewed HOT as skills for talented students, or HOT problems having a high level of difficulty and long storylines. The knowledge of existing teaching strategies, familiarity with HOT problems, and colleague-support are needed to improve the development of HOT skills in the mathematics classroom.

Published: April 2020

Cloud
computing defines the SPI model, which is generally agreed upon as providing Software-as-a-Service,
Platform-as-a-Service and Infrastructure-as-a-Service. Interest in those
service delivery models is growing because the paradigm offers to cloud
customers high computational resource on-demand with a low cost. However,
trustiness in the cloud services regarding the security and the privacy of the
delivered data is the most critical issue in the SPI model. In this paper we
propose a trusted SPI model that gives cloud customer more confidence into SPI
services by leveraging a trust in a neutral SPI certifying authority. The
proposed model prevents insider attacks from tampering with application service
before and after the computational resource was launched and allow cloud
customer to verify if its node run in a secure environment
AN EFFECT ANALYSIS OF THE PARALLEL MIGRATING BIRDS OPTIMIZATION ALGORITHM PARAMETERS
Authors: KUVAT Gültekin , TÜLEK Abdullah
Published: April 2020

Migration is the process of sending selected solutions from a sub-population to the neighboring sub-population at specified intervals in parallel metaheuristic algorithms (PMAs). Topology, migration rate (MR), migration interval (MI), migration policy and communication model are the factors which characterize the nature of migration. Identification of relationship between migration parameters and an accurate selection of such parameter values increase the performance of PMAs. The number of sub-populations (NS) denotes the number of different populations in which algorithm can perform simultaneous searches. In this study, Migrating Birds Optimization (MBO) Algorithm, no migration performed, was applied for four different NS values. Additionally, Parallel Migrating Birds Optimization (PMBO) Algorithm is executed using five MR values, five MI values and four NS values and obtained fitness values are provided. According to the results, PMBO algorithm outperforms MBO in 99% of case studies. Therefore, the contribution of migration to the performance of the algorithm is evidently demonstrated. Furthermore, the values obtained during the iterations are shown on graph to investigate the effect of MI and MR changes on search performance of algorithms. As MI decreases, it is confirmed that the algorithm produces good results in early steps of iterations, making faster searches. MR has a greater effect on performance if MI is kept low. If MI increases, the changes in MR have less affect. Additionally, the effect of MI, MR, NS values and their correlation on fitness value is analyzed with analysis of variance (ANOVA). According to the analysis, MI is identified to be the most significant factor. The least significant factor is NS. Combinations of such parameters are analyzed and it was shown that MR*MI combination has the most significant effect on performance.

Geometrical realisations of the simple permutoassociahedron by Minkowski sums
Authors: Ivanovic Jelena
Published: April 2020

This paper introduces a family of n-polytopes, PAn,c which is a geometrical realisation of simple permutoassociahedra. It has significant importance serving as a topological proof of Mac Lane's coherence. Polytopes in this family are defined as Minkowski sums of certain polytopes such that every summand produces exactly one truncation of the permutohedron, i.e. yields to the appropriate facet of the resulting sum. Additionally, it leads to the correlation between Minkowski sums and truncations, which gives a general procedure for similar geometrical realisation of a wider class of polytopes.

Published: April 2020

We obtain structural theorems for the so-called S-asymptotic and quasiasymptotic boundedness of ultradistributions. Using these results, we then analyze the moment asymptotic expansion (MAE), providing a full characterization of those ultradistributions satisfying this asymptotic formula in the one-dimensional case. We also introduce and study a uniform variant of the MAE.

Background/Aim. Identification of caries risk indicators involved in the disease development is of great importance. The aim of this study was to assess the association between distinctive risk indicators and different stages of caries disease process in children. Methods. The cross-sectional study was conducted on a sample (n = 327) of school children ages 7?11. A questionnaire submitted to parents was used to record the data regarding demographic characteristics, children's dietary habits, oral hygiene habits and oral health behaviors. Caries was assessed using the International Caries Detection and Assessment System (ICDAS) II and subjects were stratified according to the highest and most prevalent caries lesion stage. The data obtained were analyzed using the ?2 or Fisher`s exact test and multinomial logistic regression. Results. Caries lesions were detected in 56.6% of examinees observed in the study. Compared to caries-free subjects, appearance of initial caries lesions was statistically significantly influenced by maternal education level (p = 0.021), paternal occupational status (p = 0.023), toothbrushing frequency (p < 0.001), and caries status of deciduous teeth (p = 0.027). Maternal educational level (p = 0.026), paternal occupational status (p = 0.003), sweets and snacks taking frequency (p = 0.005), toothbrushing frequency (p < 0.001), and fluoridate dentifrice usage (p = 0.027) were associated with moderate caries lesions. Maternal educational level (p < 0.001), sweets and snacks taking frequency (p = 0.022) and toothbrushing frequen-cy (p < 0.001) were associated with extensive caries lesions. Maternal educational level (p = 0.02) and brushing frequency (p < 0.001) were statistically significantly associated with the highest prevalence of initial caries lesions. Maternal educational level (p = 0.025), toothbrushing frequency (p < 0.001) and frequency of dental check-ups (p = 0.016) were statistically significantly associated with the highest prevalence of moderate caries lesions. Conclusion. Parental socioeconomic indicators and children's behavior related to oral health were involved in the changes from caries-free status to different caries stages.

Published: April 2020

Background/Aim. Cholesteatoma is characterized by progressive growth with the erosion of surrounding bone due to pressure effects, enzymatic activity and activation of osteoclasts. The aim of this study was to examine the expression levels of tumor necrosis factor (TNF)-alpha receptor 2 (TNF R2) and interleukin-1 (IL-1) in chronic otitis media (COM) with and without acquired cholesteatoma and correlate them with the degree of bone destruction. Methods. The study included 178 patients of both sexes, aged 5?75 years, who underwent microsurgical treatment for COM, with and without cholesteatoma at the Ear, Nose and Throat Department, University Clinical Center of Republika Srpska (UCC RS), Banja Luka from 2015 to 2018. Based on cholesteatoma presence, the patients with COM were divided into two groups: with cholesteatoma (CCOM) (n = 97) and without cholesteatoma (COMWC) (n = 81). Samples of cholesteatoma perimatrix in the CCOM group and tympanic cavity inflamed mucosa in the COMWC group were collected intraoperatively. Intraoperative exploration of the middle ear included the status of the ossicular chain, individual ossicles, osseous walls of the external auditory canal (EAC) and tympanic cavity. Expression levels of TNF R2 and IL-1 were investigated by immunohistochemical analysis of tissue samples obtained during ear surgery. Results. The correlation between the level of osteodestruction and the presence of cholesteatoma was significant (p < 0.01). Elevated expression levels of TNF R2 and IL-1 were most frequent in CCOM patients with osteodestruction. The probability of osteodestruction of EAC and tympanic cavity walls was significantly higher in patients with high TNF R2 expression (p < 0.05). With respect to IL-1 expression levels, no significant correlation with the described pathomorphological changes was observed. Correlation between TNF R2 and IL-1 expressions and ossicular chain destruction was significant (p < 0.01). Conclusion. Cholesteatoma presence and elevated expression levels of TNF R2 and IL-1 in COM patients are significantly correlated. Expression levels of TNF R2 and IL-1 in acquired cholesteatoma tissue have a potential clinical significance for the occurrence of bone destruction compared to expression levels in inflamed mucosa of the tympanic cavity.

OBJECTIVE

Type 2 diabetes (T2D) is increasingly diagnosed at younger ages. We investigated the association of adolescent obesity with incident T2D at early adulthood.

RESEARCH DESIGN AND METHODS

A nationwide, population-based study evaluated 1,462,362 adolescents (59% men, mean age 17.4 years) during 1996–2016. Data were linked to the Israeli National Diabetes Registry. Weight and height were measured at study entry. Cox proportional models were applied.

RESULTS

During 15,810,751 person-years, 2,177 people (69% men) developed T2D (mean age at diagnosis 27 years). There was an interaction among BMI, sex, and incident T2D (Pinteraction = 0.023). In a model adjusted for sociodemographic variables, the hazard ratios for diabetes diagnosis were 1.7 (95% CI 1.4–2.0), 2.8 (2.3–3.5), 5.8 (4.9–6.9), 13.4 (11.5–15.7), and 25.8 (21.0–31.6) among men in the 50th–74th percentile, 75th–84th percentile, overweight, mild obesity, and severe obesity groups, respectively, and 2.2 (1.6–2.9), 3.4 (2.5–4.6), 10.6 (8.3–13.6), 21.1 (16.0–27.8), and 44.7 (32.4–61.5), respectively, in women. An inverse graded relationship was observed between baseline BMI and mean age of T2D diagnosis: 27.8 and 25.9 years among men and women with severe obesity, respectively, and 29.5 and 28.5 years among low-normal BMI (5th–49th percentile; reference), respectively. The projected fractions of adult-onset T2D that were attributed to high BMI (≥85th percentile) at adolescence were 56.9% (53.8–59.9%) and 61.1% (56.8–65.2%) in men and women, respectively.

CONCLUSIONS

Severe obesity significantly increases the risk for incidence of T2D in early adulthood in both sexes. The rise in adolescent severe obesity is likely to increase diabetes incidence in young adults in coming decades.
Cost and Cost-Effectiveness of Large Scale Screening for Type 1 Diabetes in Colorado
Authors: McQueen R. Brett , Geno Cristy , Waugh Kathleen , Frohnert Brigitte I. , Steck Andrea K. , Yu Liping , Baxter Judith , Rewers Marian
Published: April 2020

Objective:
To assess the costs and
project the potential lifetime cost-effectiveness of the ongoing Autoimmunity
Screening for Kids (ASK) Program, a large-scale pre-symptomatic type 1 diabetes
screening program for children and adolescents in the metro Denver region.

Research
Design and Methods: We report the resource utilization, costs, and
effectiveness measures from the ongoing ASK program as compared to usual care
(i.e., no screening). Additionally, we report a practical screening scenario by
including utilization and costs relevant to routine screening in clinical
practice. Finally, we project the potential cost-effectiveness of ASK and
routine screening by identifying clinical benchmarks (i.e., DKA events avoided,
HbA1c improvements vs. no screening) needed to meet value thresholds of $50,000
to $150,000 per quality-adjusted life year (QALY) gained over a lifetime
horizon.

Results:
Cost per case detected was $4,700
for ASK screening and $14,000 for routine screening. To achieve value
thresholds of $50,000 to $150,000 per QALY gained, screening costs would need
to be offset by cost savings through 20% reductions in DKA events at diagnosis
in addition to 0.1% (1.1 mmol/mol) improvements in HbA1c over a lifetime as
compared to no screening for patients that develop type 1 diabetes. Value
thresholds were not met from avoiding DKA events alone in either scenario.

Conclusions:
Pre-symptomatic type 1 diabetes screening may be cost-effective in areas with
high prevalence of DKA and infrastructure facilitating screening and monitoring
if the benefits of avoiding DKA events and improved HbA1c persist over long-run
time horizons. As more data
are collected from ASK, the model will be updated with direct evidence on
screening effects.
Anticipating heat accumulation in laser oxygen cutting of thick metal plates
Authors: Levichev Nikita , Costa Rodrigues Gonçalo , Dewil Reginald , Duflou Joost R.
Published: April 2020

Excessive heating of the metal sheet during laser oxygen cutting can cause quality deterioration and even lead to cut loss and possible machine idle time, especially for cutting of thick plates, where the cutting speed is slower. There are at least three different strategies to handle quality deterioration by heat accumulation in flame laser cutting of thick plates: to optimize the process parameters for preheated zones, to generate tool paths that avoid such regions, or to use active cooling to remove the excessive heat. For any of these strategies to work, it is crucial to correctly identify when and where heat accumulations occur. This can be done by real-time temperature measurements, by simulating heat propagation on the metal plate, or by defining empirical criteria based on experimental data. This paper takes a close look at these methods of heat accumulation detection, their advantages and disadvantages, and how they can be integrated into different approaches to tackle unwanted heat accumulations in laser cutting. Furthermore, three case studies are provided, one for each above-mentioned method, where the detection of quality degradation due to heat accumulation is demonstrated with a series of experiments. For all case studies, at least one action is proposed to improve the cut quality. All experiments were conducted for 15 mm mild steel plates using a 4 kW industrial fiber laser cutting machine.

The Effect of Sport on Life Skills of Athlete-Students in Different Education Levels: Mixed Research Approach
Authors: YILMAZ Aynur
Published: April 2020

The aim of the study is to examine the contribution of sports to the life skills of athletes-students. In the 2018-2019 academic year, a total of 219 athletes-students, 141 of whom are men and 78 of them are women who regularly study at different educational levels, aged between 11 and 24, participated in the study. The research was designed with a converging parallel pattern, one of the mixed research approaches. While the quantitative data of the study was obtained through the “Personal Information Form” and “The Effect of Sports on Life Skills” scale; qualitative data were obtained through the "open-ended question form". Parametric tests (independent groups t test, One-Way ANOVA, Pearson Correlation Analysis) were used in the analysis of quantitative data. In qualitative data analysis, content analysis technique was used. According to the data obtained, it was found that gender is an important variable in the effect of sports on life skills and the contribution of sports to women's life skills is higher than that of men. In addition, it was determined that the sports branch showed a significant difference. It was determined that the effect of athletes-students who are interested in athletics on the life skills of sports is higher than those who are interested in tennis. There is no relationship between sports age and the effect of sports on life skills. In the qualitative part of the research, it was stated in the statements of the participants that sports contributed significantly to individuals in terms of health, psychological / spiritual, personality, physical and cognitive development. Therefore, considering that sports have important contributions to people from all walks of life; Special applications should be given to the applications that will enable sports to take place in individuals' lives.

Published: April 2020

Bu araştırma bir devlet üniversitesinin farklı bölümlerinde öğrenim görmekte olan öğretmen adaylarının siber aylaklık puanlarının çeşitli değişkenler açısından incelenmesini amaçlamaktadır. Bu bağlamda öğretmen adaylarının siber aylaklık puanlarının demografik özellikler (cinsiyet, bölüm), öğrenim gördükleri bölümden memnuniyetleri ve bölümü tercih sıralamaları ile internet kulanım davranışları (gün içinde internet kullanım sıklığı ve internet kullanma becerileri) açısından farklılaşıp farklılaşmadığı belirlenmeye çalışılmıştır. Bu amaç doğrultusunda Akbulut, Dursun, Dönmez ve Şahin (2016) tarafından geliştirilen “Öğrenme Etkinlikleri Sırasında Bilgi ve İletişim Teknolojileri Kullanımı Ölçeği” ve araştırmacı tarafından hazırlanan kişisel bilgi formu uygulanmıştır. Araştırma nicel araştırma yöntemlerinden tarama modeli kullanılarak yürütülmüştür. Katılımcılar 2018-2019 eğitim öğretim yılı bahar döneminde bir devlet üniversitesinin eğitim fakültesinde farklı bölümlerde öğrenim görmekte olan 207 öğretmen adayından oluşmaktadır. Araştırmanın bulgularına göre, öğretmen adaylarının siber aylaklık toplam puanlarında cinsiyet ve bölümden memnuniyet değişkenleri açısından anlamlı bir farklılık olmadığı sonucuna varılmıştır. Ancak, öğrenim görmekte oldukları bölüm, günlük internet kullanma süreleri ve internet kullanma becerileri açısından anlamlı farklılık olduğu belirlenmiştir. Bunun yanısıra öğretmen adaylarının bölüm tercih sıralamaları ile siber aylaklık toplam puanları arasında anlamlı bir ilişki olmadığı görülmüştür.

A razão agoniza em uma casa vazia: modernismo arquitetônico no filme O Desafio
Authors: Pinto Carlos Eduardo
Published: April 2020

Paulo César Saraceni’s The dare (1965) is a milestone of the Brazilian Cinema Novo. Considered the first cinematographic movie to openly address the 1964 civil-military coup, it also inaugurated a lineage of intimate Rio films, committed to reading beyond the representation of the city through postcard images. The film pays special attention to the scenarios, especially houses and apartments, defining the political and psychological contours of the characters through their interaction with the environments. In this article I make explicit the impact caused by this new form of urban representation and, finally, I make the analysis of two sequences, in which an almost empty modernist house is set against a burning, ruined pension. The aim is to demonstrate that, while the contours of these scenarios define the protagonists’ conflicts, the actions taken in each environment add meaning to the architecture.
História escrita com imagens: as fotografias dos profetas de Congonhas do Campo por Marcel Gautherot
Authors: Mannarino Ana
Published: April 2020

The photographs by Marcel Gautherot documenting the sculptures of the Twelve Prophets, at Congonhas do Campo, attributed to Antonio Francisco Lisboa, the Aleijadinho, go beyond the purpose of recording the works. They also contribute to the writing of history, through the images produced. In accordance with the SPHAN orientation, which aimed to construct a Brazilian art history that valorized the artistic production of the colonial period, the images by Gautherot help in a decisive way to consolidate the Aleijadinho myth, not only for their documental significance and widespread circulation, but also for the regard the photographer develops about the works. The images direct the regard and build a discourse, through framing, lighting and point of views assumed, leading to the identity between the work photographed and its author.
Paisagem e natureza na arte contemporânea: ressignificação do espaço e experiência da obra
Authors: França Ana Marcela
Published: April 2020

This paper aims to discuss the installations made in the 1970s to the present day, which dialogue directly with the “natural” landscape, extending the significance of the artistic object to the reconfiguration of the space. In particular, works that have action in the biophysical space will be discussed, in which elements of the environment become devices of artistic manifestation. It will be seen that these performances transform the landscape and the notion of a work of art, creating tensions in what we understand as nature and culture.

Determinantes do crédito
Authors: Santos Priscila Soares dos , Moreira Roni Barbosa
Published: April 2020

O microcrédito ganhou destaque no Brasil e no mundo como uma modalidade de empréstimos para os microempreendedores, sobretudo os localizados no setor informal. No estado do Espírito Santo, em exemplo, a experiência de destaque é o Programa Nossocrédito, que conta com um grande número de atendimentos ao longo de seus anos de funcionamento. O objetivo deste trabalho é analisar os determinantes do crédito do Programa Nossocrédito do Espírito Santo no período de 2013 a 2015. Para tal, foram estudadas as relações das variáveis socioeconômicas como renda, população e o IFDM, bem como as variáveis sexo e setor para onde o crédito é destinado, além do faturamento bruto dos microempresários, para verificar se essas variáveis exercem algum efeito sobre o nível médio de crédito concedido pelo programa aos municípios capixabas. Como instrumento,  utilizou-se de modelagem econométrica do tipo dados em painel com efeitos fixos. Os resultados encontrados apontaram para um efeito positivo da população e do PIB per capita dos municípios no valor médio de crédito concedido, o que demonstra que o programa atende majoritariamente aos municípios mais populosos e com maiores PIB per capita. Em contrapartida, os municípios considerados menos desenvolvidos pelo IFDM, que destinam mais créditos para o setor informal e para tomadores do sexo feminino, contaram com um menor valor médio de crédito emprestados.  Conclui-se que as variáveis socioeconômicas exercem influência sobre a quantidade de crédito fornecida pelo programa e que o Nossocrédito apresenta algumas dificuldades para atender ao público alvo dos programas de microcrédito.

Aim

A validated algorithm for automatic aortic arch measurements in aortic coarctation (CoA) patients could standardize procedures for clinical planning.

Methods

The model-based assessment of the aortic arch anatomy consisted of three steps: first, machine-learning-based algorithms were trained on 212 three-dimensional magnetic resonance (MR) data to automatically allocate the aortic arch position in patients and segment the aortic arch; second, for each CoA patient (N = 33), the min/max aortic arch diameters were measured using the proposed software, manually and automatically, from noncontrast-enhanced three-dimensional steady-state free precession MRI sequence at five selected sites and compared (‘internal comparison’ referring to the same environment); third, moreover, the same min/max aortic arch diameters were compared, obtaining them independently, manually from common MR management software (MR Viewforum) and automatically from the model (external comparison). The measured sites were: aortic sinus, sino–tubular junction, mid-ascending aorta, transverse arch and thoracoabdominal aorta at the level of the diaphragm.

Results

Manual and software-assisted measurements showed a good agreement: the difference between diameter measurements was not statistically significant (at α = 0.05), with only one exception, for both internal and external comparison. A high coefficient of correlation was attained for both maximum and minimum diameters in each site (for internal comparison, R > 0.73 for every site, with P < 2 × 10−5). Notably, in tricuspid aortic valve patients external comparison showed no statistically significant difference at any measurement sites.

Conclusion

The automatically derived aortic arch model, starting from three-dimensional MR images, could be a support to take the measurements in CoA patients and to quickly provide a patient-specific model of aortic arch anomalies.
Silver and zinc nanoparticles in animal nutrition – a review
Authors: Bąkowski Maciej , Kiczorowska Bożena , Samolińska Wioletta , Klebaniuk Renata
Published: April 2020

The use of metal nanoparticles as supplements of animal diets does not always bring unambiguous results. There are many reports in the literature about the multifaceted effects of this type of supplementation on the animal organism. Therefore, the aim of the paper is to present the current knowledge of the possible application of nanometal forms in animal nutrition and its potential benefits and threats. The positive effect of nanoparticles used as feed additives has most frequently been reflected in an increase in body weight, higher average daily gain, or improvement of the FCR value. In some cases, however, the effect of nanoparticle addition to diets was indiscernible. The potent antibacterial activity of nanoparticles, especially against Gram-negative bacteria and Gram-positive bacteria, is regarded as a positive effect. In turn, the probability of their toxicity is a potential risk in application thereof. Supplementation of diets with nanometals has been accompanied by pathological changes in animal tissues, primarily in the pancreas, kidney, liver, rumen, abomasum, small intestine, adrenal glands, and brain. Additionally, at the the cellular level, nanoparticles were found to induce toxicity, inflammatory excitation, and cell death. Oral administration of nanoparticles induced a risk of malfunction of the nervous system and even impairment of cognitive processes in animals. The increasing knowledge of the possible toxic effects of nanoparticles on the animal organism suggests caution in their use in animal production and necessitates further precise investigations in this area.
