Background: Salmonella species and Escherichia coli (E. coli) are important foodborne pathogens affecting humans and animals. They are among the most important causes of infection that are associated with the consumption of contaminated food. This study was aimed to determine the prevalence, antimicrobial susceptibility patterns and associated risk factors for Salmonella species and E. coli in raw meat from butchery houses of Mekelle, Northern Ethiopia.MethodA cross-sectional study was conducted from January to December 2019. Socio-demographic data and risk factors were collected using a predesigned questionnaire. Meat samples were collected aseptically from the butchery houses and transported using icebox to Mekelle University, College of Veterinary Sciences for the isolation and identification of Salmonella species and E. coli. Antimicrobial susceptibility patterns were determined using Kirby disc diffusion method. Data obtained were cleaned and entered into Statistical Package for the Social Sciences version 22 and logistic regression models with odds ratio were calculated. P-value < 0.05 was considered as statistically significant.ResultsA total of 153 out of 384 (39.8%) of the meat specimens were found to be contaminated. The contamination of Salmonella species and E. coli were 15.6% (n=60) and 20.8%) (n=80), respectively. Mixed contamination (Salmonella species and E. coli) was observed in 13 (3.4 %) of the analyzed. Poor washing hands regularly (AOR = 8.37; 95% CI: 2.75-25.50) and not using gloves during meat handling (AOR=11. 28; 95% CI: (4.69‑27.10) were associated with an overall bacterial contamination About 95.5% of the tested isolates were sensitive to chloramphenicol and norfloxacin while the resistance of amoxyclav_amoxicillin and erythromycin were both isolated bacteria species. The overall multidrug resistance pattern for Salmonella and E. coli were 51.4% (n=19) and 31.8% (14), respectively.ConclusionOf the 153 (153/384) contaminated raw meat, 60 (15.6%) and 80 (20.8%) were contaminated by Salmonella species and E. coli, respectively.

Published: June 2020

Los escenarios educativos digitales requieren el diseño de métodos de evaluación que promuevan la participación, la actividad cognitiva y la colaboración entre estudiantes. En este sentido en la etapa de evaluación entre pares de la metodología SOOC se enfatiza la retroalimentación entre pares como un proceso que contribuye a su aprendizaje. El objetivo de este trabajo fue diseñar un guion para elaborar una retroalimentación entre pares considerando las características de la retroalimentación que realizaron los aprendices durante esta etapa en un curso en línea. Se encontró que las categorías más frecuentes fueron identificación, cortesía, formación, motivación y apropiación, mostrando un grado de pensamiento reflexivo. Asimismo, las categorías de motivación y cortesía proveen rasgos afectivos que contribuyen al aprendizaje colaborativo y la categoría interrogación favorece cuestionamientos para solicitar claridad a la actividad que se evalúa. Por ello, se retoman las seis categorías para proponer un guion para elaborar retroalimentaciones que favorezcan al aprendizaje del estudiante y sus compañeros que pueda emplearse a futuro en la metodología SOOC.

Published: June 2020

Actualmente, las redes sociales virtuales son uno de los recursos más utilizados por jóvenes y adolescentes, lo que conlleva que sus niveles de adición también se estén viendo incrementados. Tomando como base este hecho, se presenta una investigación que tiene como objetivo analizar las percepciones que los estudiantes y que sus profesores tienen sobre los grados de adicción a las redes sociales que presentan. La muestra la conforman 17600 estudiantes de México, de los que 15751 realizaban sus estudios online y 1849 de forma presencial, y 1498 docentes, 1222 de las modalidades de enseñanza en línea y 276 de la presencial. El instrumento utilizado para establecer los niveles de adicción es el cuestionario “Social Media Addiction Scale-Student Form” (SMAS-SF), adaptado y fiabilizado al contexto mexicano. Entre los resultados destaca que, en general, los estudiantes no consideran que presentan altos niveles de adicción, frente al profesorado que señala lo contrario. Además, son los estudiantes que desarrollan sus estudios de forma presencial los que muestran mayor grado de adicción a las redes sociales.
Mid- to long-term runoff prediction by combining the deep belief network and partial least-squares regression
Authors: Yue Zhaoxin , Ai Ping , Xiong Chuansheng , Hong Min , Song Yanhong
Published: June 2020

Data representation and prediction model design play an important role in mid- to long-term runoff prediction. However, it is challenging to extract key factors that accurately characterize the changes in the runoff of a river basin because of the complex nature of the runoff process. In addition, the low accuracy is another problem for mid- to long-term runoff prediction. With an aim to solve these problems, two improvements are proposed in this paper. First, the partial mutual information (PMI)-based approach was employed for estimating the importance of various factors. Second, a deep learning architecture was introduced by using the deep belief network (DBN) with partial least-squares regression (PLSR), together denoted as PDBN, for mid- to long-term runoff prediction, which solves the problem of parameter optimization for the DBN using PLSR. The novelty of the proposed method lies in the key factor selection and a novel forecasting method for mid- to long-term runoff. Experimental results demonstrated that the proposed method can significantly improve the effect of mid- to long-term runoff prediction. Also, compared with the results obtained by current state-of-the-art prediction methods, i.e., DBN, backpropagation neural networks, and support vector machine models, our prediction results demonstrate the performance of the proposed method.
A varying comprehensive hydropower coefficient for medium/long-term operation of a single reservoir
Authors: Gong Wenting , Liu Pan , Cheng Lei , Li He , Yang Zhikai
Published: June 2020

In medium/long-term reservoir operation, the hydropower output is calculated from k × q × h, where q is the power discharge, h is the water head, and k is the comprehensive hydropower coefficient. k indicates the conversion efficiency from water power to electricity, however, it is standard practice to use a constant k. We developed a novel method to derive the varying k based on observed big data. The operational frequencies of different units for time (multiple periods) and space (multiple units) were accounted based on the observed big data from each unit, and then weights were obtained. Finally, k was derived by integrating the efficiency curves (hill charts) of the different units with their weights. The Three Gorges Project, China, was selected for a case study. Results indicated that: (1) the varying k value can improve hydropower simulation accuracy, (2) simulations using 10-day intervals have a higher accuracy for hydropower calculation than daily and monthly scales, (3) the evaluation of hydropower plant benefits is sensitive to k, and there is potential for producing more hydropower. These findings are highly relevant to the operation of hydropower plants and to the evaluation of medium/long-term hydropower generation for a hydropower plant.

Authors: Slavik Irene , Oliveira Keila Roberta , Cheung Peter Batista , Uhl Wolfgang
Published: June 2020

In many parts of the world, drinking water storage takes place in near-house or in-house tanks. This can impact drinking water quality considerably. International and numerous national standards and guidelines addressing the construction, installation and operation of domestic drinking water storage tanks are reviewed on their consideration of water quality aspects and the minimisation of health risks associated with drinking water storage. Several national and international standards and guidelines are reviewed in terms of drinking water quality requirements. Factors that have an impact on water quality in relation to the use of domestic drinking water storage tanks are summarised comprehensively. The impact of the domestic storage of drinking water on water quality, the points and locations of use, their positioning, the materials they are made of, their design and operation, as well as aspects of how they are operated and maintained is outlined and discussed in detail. Finally, the incorporation of aspects regarding water quality in drinking water storage tanks in standards and guidelines is presented and assessed. To make the use of domestic drinking water storage tanks safer and more efficient, recommendations for modifications, improvements and extensions of respective standards are made.
Study on the efficient removal of azo dyes by heterogeneous photo-Fenton process with 3D flower-like layered double hydroxide
Authors: Bao Siqi , Shi Yuqi , Zhang Youshan , He Longjie , Yu Wangyang , Chen Zexiang , Wu Yunfeng , Li Leijiao
Published: June 2020

As organic dyes are the main pollutants in water pollution, seeking effective removal solutions is urgent for humans and the environment. A novel environmentally friendly three-dimensional CoFe-LDHs (3D CoFe-LDHs) catalyst was synthesized by one-step hydrothermal method. Scanning electron microscopy, energy dispersive spectroscopy, Fourier transform infrared spectra, X-ray diffraction, X-ray photoelectron spectroscopy, Brunauer-Emmett-Teller technique as well as UV-Vis diffuse reflectance spectra were used to characterize the prepared samples. The experimental results revealed that 3D CoFe-LDHs exhibited a rapid decolorization of methyl orange and Rhodamine B by heterogeneous photo-Fenton process after reaching the adsorption equilibrium, and the final decolorization efficiency reached 91.18% and 93.56%, respectively. On the contrary, the decolorizing effect of 3D CoFe-LDHs on neutral blue was relatively weak. The initial concentrations of azo dyes, pH and H2O2 concentration affected the decolorization of dyes and the catalyst maintained excellent reusability and stability after reuse over five cycles. The quenching experiments found that •OH, •O2− and h+ were the main active substances and reaction mechanisms were further proposed. The study suggests that the synergistic effect of photocatalysis and Fenton oxidation process significantly improved the removal of azo dyes and the synthesized catalyst had potentially promising applications for difficult-to-biodegrade organic pollutants in wastewater.
Preoperative Circulating MiR-210, a Risk Factor for Postoperative Delirium Among Elderly Patients with Gastric Cancer Undergoing Curative Resection
Authors: Chen Yun , Zheng Jinwei , Chen Junping
Published: June 2020

Background:

Postoperative delirium (POD) is a very common complication in elderly patients with
gastric cancer (GC) and associated with poor prognosis. MicroRNAs (miRNAs) serve as key post-transcriptional
regulators of gene expression via targeting mRNAs and play important roles in the nervous system. This study
aimed to investigate the potential predictive role of miRNAs for POD.

Methods:

Elderly GC patients who were scheduled to undergo elective curative resection were consequently
enrolled in this study. POD was assessed at 1 day before surgery and 1-7 days after surgery following the guidance
of the 5th edition of Diagnostic and Statistical Manual of Mental Disorders (DSM V, 2013).
The demographics, clinicopathologic characteristics and preoperative circulating miRNAs by quantitative reverse
transcription-polymerase chain reaction (qRT-PCR) were compared between patients with or without POD. Risk
factors for POD were assessed via univariate and multivariate logistic regression analyses.

Results:

A total of 370 participants were enrolled, of which 63 had suffered from POD within postoperative 7
days with an incidence of 17.0%. Preoperative miR-210 was a predictor for POD with an area under the curve
(AUC) of 0.921, a cut-off value of 1.67, a sensitivity of 95.11%, and a specificity of 92.06%, (P<0.001). In the
multivariate logistic regression model, the relative expression of serum miR-210 was an independent risk factor
for POD (OR: 3.37, 95%CI: 1.98–5.87, P=0.003).

Conclusions:

In conclusion, the present study highlighted that preoperative miR-210 could serve as a potential
predictor for POD in elderly GC patients undergoing curative resection.

Authors: Nayeri Tooran , Sarvi Shahabeddin , Moosazadeh Mahmood , Hosseininejad Zahra , Amouei Afsaneh , Daryani Ahmad
Published: June 2020

Background:

The impact of infectious agents, such as Toxoplasma gondii (T. gondii),
on human behavior and mental disorders, has recently attracted the attention of researchers. T. gondii
has emerged as a suitable candidate for such disorders due to its neutral nature. Therefore, the
current study aimed at investigating the possible relationship between T. gondii infection and headache.

Methods:

Five databases were thoroughly searched (up to October 4, 2019) for articles on the prevalence
of T. gondii in headache sufferers. In this study, the odds ratio (OR) and corresponding
95% confidence interval (CI) were estimated using a random effect model and forest plot to gauge
effect size and effect of each study.

Results:

A total number of four articles, including one cross-sectional and three case-control
studies 2517 participants, entered the meta-analysis, out of whom, 1205 subjects were afflicted
with headache or migraine (17.67% positive for toxoplasmosis) and 1312 participants were not
(18.29% for toxoplasmosis). The results of the meta-analysis indicated a common OR of 1.59
(95% CI: 1.03-2.47) by the random effect model.

Conclusion:

The obtained results of several studies have linked toxoplasmosis and headache.
Therefore, more quality studies with larger sample sizes are needed to determine the detailed association
between headache and T. gondii infection for the prevention and control of toxoplasmosis
among headache sufferers.

Authors: Smith Alexander , Bains Natalie , Copeland Lauren , Pennington Anna , Carter Ben , Hewitt Jonathan
Published: June 2020

BACKGROUND

Knowledge of the prevalence of morbidity secondary to stroke is important for health care professionals, health care commissioners, third sector organizations, and stroke survivors to understand the likely progress of poststroke sequelae and to aid in commissioning decisions, planning care, and adjusting to life after stroke.

OBJECTIVE

The primary aim of the Morbidity PRevalence Estimate In StrokE (MORe PREcISE) study is to determine the prevalence of morbidity secondary to a stroke, predictors of morbidity, and trends in quality of life and functional status using patient-reported outcomes, cognitive and functional assessments.

METHODS

A total of 500 participants will be recruited across Wales and England within 14 days following an admission to a stroke unit for either an ischemic or hemorrhagic stroke as part of a multicenter cohort study. Participants are assessed at baseline ≤14 days poststroke and subsequently at 90 (± 14) days and 180 (± 14) days poststroke. At each time point, data will be collected relating to the following domains: participant demographics, routine clinical, patient reported, cognitive status, emotional well-being, and functional ability.

RESULTS

Recruitment commenced in October 2018 with 20 sites opened as of September 2019 and was closed on October 31, 2019.

CONCLUSIONS

The primary outcome is the prevalence of morbidity at 6 months secondary to a stroke. Further analysis will consider temporal changes in the health-related domains to describe trends among baseline, 3-, and 6-month time points.

Authors: Leenen Jobbe PL , Leerentveld Crista , van Dijk Joris D , van Westreenen Henderik L , Schoonhoven Lisette , Patijn Gijsbert A
Published: June 2020

BACKGROUND

Continuous monitoring of vital signs by using wearable wireless devices may allow for timely detection of clinical deterioration in patients in general wards in comparison to detection by standard intermittent vital signs measurements. A large number of studies on many different wearable devices have been reported in recent years, but a systematic review is not yet available to date.

OBJECTIVE

The aim of this study was to provide a systematic review for health care professionals regarding the current evidence about the validation, feasibility, clinical outcomes, and costs of wearable wireless devices for continuous monitoring of vital signs.

METHODS

A systematic and comprehensive search was performed using PubMed/MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials from January 2009 to September 2019 for studies that evaluated wearable wireless devices for continuous monitoring of vital signs in adults. Outcomes were structured by validation, feasibility, clinical outcomes, and costs. Risk of bias was determined by using the Mixed Methods Appraisal Tool, quality assessment of diagnostic accuracy studies 2nd edition, or quality of health economic studies tool.

RESULTS

In this review, 27 studies evaluating 13 different wearable wireless devices were included. These studies predominantly evaluated the validation or the feasibility outcomes of these devices. Only a few studies reported the clinical outcomes with these devices and they did not report a significantly better clinical outcome than the standard tools used for measuring vital signs. Cost outcomes were not reported in any study. The quality of the included studies was predominantly rated as low or moderate.

CONCLUSIONS

Wearable wireless continuous monitoring devices are mostly still in the clinical validation and feasibility testing phases. To date, there are no high quality large well-controlled studies of wearable wireless devices available that show a significant clinical benefit or cost-effectiveness. Such studies are needed to help health care professionals and administrators in their decision making regarding implementation of these devices on a large scale in clinical practice or in-home monitoring.
Artificial Intelligence for COVID-19: Rapid Review (Preprint)
Authors: Chen Jiayang , See Kay Choong
Published: June 2020

BACKGROUND

COVID-19 was first discovered in December 2019 and has since evolved into a pandemic.

OBJECTIVE

To address this global health crisis, artificial intelligence (AI) has been deployed at various levels of the health care system. However, AI has both potential benefits and limitations. We therefore conducted a review of AI applications for COVID-19.

METHODS

We performed an extensive search of the PubMed and EMBASE databases for COVID-19–related English-language studies published between December 1, 2019, and March 31, 2020. We supplemented the database search with reference list checks. A thematic analysis and narrative review of AI applications for COVID-19 was conducted.

RESULTS

In total, 11 papers were included for review. AI was applied to COVID-19 in four areas: diagnosis, public health, clinical decision making, and therapeutics. We identified several limitations including insufficient data, omission of multimodal methods of AI-based assessment, delay in realization of benefits, poor internal/external validation, inability to be used by laypersons, inability to be used in resource-poor settings, presence of ethical pitfalls, and presence of legal barriers. AI could potentially be explored in four other areas: surveillance, combination with big data, operation of other core clinical services, and management of patients with COVID-19.

CONCLUSIONS

In view of the continuing increase in the number of cases, and given that multiple waves of infections may occur, there is a need for effective methods to help control the COVID-19 pandemic. Despite its shortcomings, AI holds the potential to greatly augment existing human efforts, which may otherwise be overwhelmed by high patient numbers.

Exploring Teachers’ Conceptual Uses of Research as Part of the Development and Scale up of Research-Informed Practices
Authors: Flood Jane , Brown Chris
Published: June 2020

This article examines the idea of research-informed teaching practice (RITP) and how such practice can best be facilitated to improve aspects of teaching and learning. After first exploring RITP as a concept, the paper then engages with Carol Weiss’ seminal typology of research-use, and makes the argument that Weiss’ notion of conceptual research-use is both more likely and more realistic than instrumental research-use. The paper then illustrates how the idea of conceptual research-use aided the design of a small-scale project that sought to help teachers engage with and employ research, such that this engagement might impact positively on teaching and learning. In-depth semi structured interviews were undertaken with 15 project participants to examine whether the approach employed by the project: 1) helped teachers engage with research; 2) helped teachers develop new strategies for teaching and learning; and 3) whether the strategies developed by teachers were thought to impact on practice and student outcomes. Analysis of the interview data indicates that the approach employed has enabled teachers to successfully engage with research and use research to improve teaching and learning. Furthermore, the analysis also provides clues regarding effective ways to replicate research-informed teaching strategies in new settings and contexts.

O artigo analisa alguns aspectos que evidenciaram a ação da Igreja Católica na configuração das lutas agrárias no Brasil entre as décadas de 1950 a 1980. Entende-se ser um período efervescente de lutas sociais em torno do que se convencionou chamar de “questão agrária brasileira”. O objetivo é demonstrar a mediação da referida instituição, as disputas internas, as ambiguidades nas ações e sua intensa influência na constituição e nas ações iniciais do Movimento dos Agricultores Sem Terra (MST). As fontes utilizadas foram leituras sobre o tema e o contexto político e econômico brasileiro do período, mas, em particular, boletins, documentos, cartas, relatórios, dentre outros, frutos de encontros, seminários e assembleias efetivados pela oficialidade da Igreja Católica e publicados pela CNBB no período em questão. As conclusões que se chega são que houve várias disputas no interior da instituição religiosa em torno das diretrizes de suas ações no horizonte social e no meio rural em particular; sempre houve uma preocupação com as questões que envolviam o pequeno agricultor e o modelo de desenvolvimento que produziam sua exclusão. Essa experiência de inserção social lhe deu credenciais para a mediação na efetivação do MST.
O medievo e a forja de um adversário: O Islã em Al-Andaluz
Authors: Rocha Augusto Machado
Published: June 2020

Parto da ideia de representação, baseado nos escritos de Chartier e Ginzburg, buscando perceber a definição do ser a partir do não ser, analisando a motivação e contexto de formação da imagem do inimigo muçulmano em Al-Andaluz, a partir dos escritos de Eulógio de Córdoba. Busco demonstrar o papel dos “Mártires de Córdoba” na formação e propagação da representação do Islã – pensando nas formas que uma escrita “local”, e seu contexto, oportunizaram uma imagem de aversão à cultura islâmica.

Ti6Al4V alloy exhibits good biocompatibility and has a wide range of applications in the medical fields. Additive manufacturing, especially selective laser melting (SLM), provides a new and effective way for the fabrication of Ti6Al4V alloy biological components. The corrosion resistance of SLM processed Ti6Al4V alloy needs further investigation, which is important for the application of biological components. In this study, Ti6Al4V alloy was fabricated by SLM using different process parameters. Electrochemical measurements including open circuit potential, potentiodynamic polarization, and electrochemical impedance spectroscopy were performed to study the influence of laser scan speed on the corrosion behavior of SLM fabricated Ti6Al4V specimens. The corrosion resistance on different planes of SLM fabricated Ti6Al4V alloy was further characterized. The electrochemical measurements indicated that the corrosion resistance was reduced as the laser scan speed increased. Microstructure analysis suggested that the inferior corrosion resistance under a high laser scan speed was related to the decreased densification behavior. Compared to the XZ-plane, the XY-plane possesses a superior corrosion resistance. The anisotropic corrosion resistance on XY- and XZ-planes of SLM fabricated Ti6Al4V alloys is attributed to the different microstructures on different planes, where more α′ martensite and less β-Ti phase were formed on the XZ-plane than on the XY-plane.
The Etiology of COVID-19 in Silico by SARS-Cov-2 Infection with the Quantum Microrna Language-AI
Authors: YR Fujii
Published: June 2020

Objective: Coronavirus disease 2019 (COVID-19) is complexed infectious disease caused by severe respiratory syndrome (SARS) human coronavirus 2 (CoV-2). We have previously shown that the microRNA (miRNA) entangling sorter (METS) analysis with quantum miRNA/miRNA language is available for the etiology investigation in silico of human virus-associated diseases. To investigate COVID-19 etiology, SARS-CoV-2 infection was simulated by METS algorithm with artificial intelligence (AI) machine learning (MIRAI). Materials and Methods: The information of coronavirus was extracted from database. Putative CoV-2 miRNAs were predicted by functionally analogy analysis. Statistical data was calculated by Prediction One. Results: The quantum miRNA immunity was observed in SARS-CoV-2 infection. Acute inflammation and viral infection mechanisms in COVID-19 were independently shown in host and viral miRNA networks according to the output of MIRAI. SARS-CoV-2 infection induced IL-6 upregulation by downregulation of miR-98-5p hub, and hypoxia was induced protein HIF1A suppression by viral miRNAs. C1q complement inhibition was tuned by viral miRNAs. Conclusion: We found in silico that COVID-19 might show IL-6 production by host miRNAs, and hypoxic vascular hypertension and hypocomplementemia-like symptom by viral miRNAs.

ResumoEste artigo trata de uma pesquisa bibliográfica que tem por objetivo analisar dissertações e teses que investigaram o pensamento algébrico nos anos iniciais do Ensino Fundamental. O referencial teórico salienta um modelo dominante de ensino da Álgebra reduzido a uma Aritmética generalizada no Ensino Fundamental, que será bruscamente algebrizado no Ensino Médio. E na atual proposta da BNCC temos a algebrização do currículo desde os anos iniciais. Foram adotadas algumas palavras chave relacionadas ao pensamento algébrico para o levantamento dos trabalhos no banco de teses e dissertações da Coordenação de Aperfeiçoamento de Pessoal do Nível Superior (Capes). Em relação ao tema pensamento algébrico nos anos iniciais do Ensino Fundamental, foram encontrados onze trabalhos sobre sequências didáticas ou a produção escrita dos alunos e dois trabalhos sobre o professor dos anos iniciais. E podemos dizer também que nenhum dos estudos está relacionado à análise de materiais didáticos e existe, nesse levantamento, apenas um trabalho envolvendo a BNCC. Palavras-chave: Pensamento algébrico; Anos Iniciais; BNCC.AbstractThis article refers to a bibliographic research that aims to analyze dissertations and thesis that investigated algebraic reasoning in the early years of Elementary School. The theoretical framework highlights a dominant model of teaching Algebra reduced to a generalized Arithmetic in Elementary School, which will be sharply algebraized in High School. And the current proposal of the Base Nacional Comum Curricular (BNCC) (National Common Curricular Base) present an algebraized curriculum since the early years. Some keywords related to algebraic reasoning were adopted to survey the work in the thesis and dissertation database of the Coordenação de Aperfeiçoamento de Pessoal do Nível Superior (Capes) (Coordination for the Improvement of Higher Education Personnel). Regarding the theme algebraic reasoning in the early years of Elementary School, eleven works were found on didactic sequences or the student’s' written production and two works on the teacher of the early years. And we can also say that none of the studies is related to the analysis of teaching materials and there is, in this survey, only one work involving BNCC.Keywords: Algebraic reasoning; Elementary Education; BNCC.

Timor island consists of five districts and one city, namely Kupang District, South Central Timor District, North Central Timor, Belu District, Malaka District, and Kupang City. On the Timor island, it has natural tourist destinations, culinary tours, cultural and historical attractions most on the island of Timor. The Ant Colony Optimization (ACO) Algorithm is very unique compared to the other nearby search algorithm, this algorithm adopted because of Ant Colony who were looking for food from the nest to food sources by leaving a footprint called Pheromone. Mapping system algorithm using ant, tourist sites can show the shortest route between two points is desired. Ants algorithm proved to be applied in determining the optimum route, but still has the disadvantage of dependence on the parameter value is not maximized. From the test results based on parameters of the cycle and the number of ants affects the simulation time, for ant algorithm parameters. From the test results based on the parameters, α and β affects, number of node, the simulation time and the shortest distance varying toward the destination even if the starting location and ending on the same location.
Infant and Young Child Feeding in Croatian Nursing Programs
Authors: Vidović Roguljić Ana , Zakarija-Grković Irena
Published: June 2020

Introduction. Breastfeeding rates in Croatia are far from WHO recommendations, with only 8% of women exclusively breastfeeding at 6 months. Nurses play a key role in supporting optimal infant feeding; therefore, their undergraduate training should cover this topic.

Aim. The aim of this study was to determine if infant feeding is part of undergraduate nursing programs in Croatia, and to analyse relevant textbooks.

Methods. Between January and March 2019, all publicly available nursing undergraduate curricula (N=9) for the 2018/2019 academic year were assessed. Required textbooks were analysed by two independent assessors using the WHO Infant and Young Child Feeding: Model Chapter for textbooks for medical students and allied health professionals.

Results. Infant feeding was included in all the curricula. The mean number of topics from the Model Chapter covered in the four evaluated textbooks was 30.4%, of which 2.7% were classified as correct and thorough, 21% as correct and brief, and 6.7% as incorrect. Fields most poorly covered were: ‘Policy, health system and community actions’ and ‘Appropriate feeding in exceptionally difficult circumstances’.

Discussion. This is one of only a few published studies looking at nursing textbook content related to infant feeding. Less than a third of topics, considered mandatory for health professional education, were covered in the required textbooks.

Conclusion. Even though infant feeding was part of all assessed nursing curricula in Croatia, the required textbooks were largely outdated, incomplete and at times incorrect.
