Dynamic Pricing Policy Using Preservation Technology with Stock and Price Sensitive Demand
Authors: Khedlekar Uttam Kumar , Singh Priyanka , Gupta Neelesh
Published: April 2021

This paper aims to develop a dynamic pricing policy for deteriorating items with price and stock dependent demand. In declining market demand of items decreases with respect to time and also after a duration items get outdated. In this situation it needs a pricing policy to sale the items before end season. The proposed dynamic pricing policy is applicable for a limited period to clease the stock. Policy decision regarding the selling price could aggressively attracts the costumers. Objectives are to maximize the prot/revenue, pricing strategy and economic order level for such a stock dependent and price sensitive items. We are giving numerical example and simulation to illustrate the proposed model.

Authors: Abdel-Sattar Rashad Abdel-Baky , Unluturk Yasin
Published: April 2021

We construct a developable surface normal to a surface along a curve on the surface. As differs from the work Hananoi, we choose the curve as the normal direction curve on which the new surface is formed in Euclidean space. We obtain some results about the uniqueness and the singularities of such developable surfaces. We also give two invariants of curves on a surface which characterize singularities.

Two sides of the same coin? How quality improvement can be used to augment program evaluation in health professions education to promote social accountability
Authors: Brown Allison , Grierson Lawrence
Published: April 2021

Health professions education is in constant pursuit of new ways of
teaching and assessment in order to improve the training of healthcare
professionals. Educators are often challenged with designing,
implementing, and evaluating programs in the context of their
professional practice, particularly those in response to dynamic and
emerging social needs. This article explores the synergies and
intersections of two approaches – quality improvement and program
evaluation – and the potential utility of their combinations within our
field to design, evaluate, and most importantly, improve educational
programming. We argue that the inclusion of established quality
improvement frameworks within program evaluation provides a proven
mechanism for driving change, can optimize programming within the
multi-contextual education systems, and, ultimately, that these two
approaches are complementary to one another. These combinations hold
great promise for optimizing programming in alignment with social
missions, where it has been difficult for institutions worldwide to
generate and capture evidence of social accountability.
Evaluation and Comparison of the GWR Merged Precipitation and Multi-Source Weighted-Ensemble Precipitation based on High-density Gauge Measurement.
Authors: Zhao Jing , Qiqi Yuan , Yang Long , Wu Hao , Wang lachun
Published: April 2021

Accurate estimation of precipitation in both space and time is essential
for hydrological research. We compared multi-source weighted ensemble
precipitation (MSWEP) with multi-source fused satellite precipitation
(CHIRPS) based on high-density rain gauge precipitation observations in
the Taihu Lake basin. We proposed a new merge precipitation algorithm
GWRMP based on the geographically weighted regression (GWR) method.
GWRMP corrects the bias of MSWEP by using high-density rain gauge
precipitation to address the common problem of daily precipitation
underestimation in MSWEP. The large-scale spatial coverage of the water
surface in this region leads to the uneven distribution of rain gauges
on the lake. There are differences in the descriptive ability of the
three spatial precipitation types, MSWEP, GWRMP, and IDW, for spatial
and temporal precipitation information in the Taihu Lake basin. A
comparison shows that GWRMP has a significant advantage in obtaining the
spatial and temporal variability of precipitation in areas with complex
topographic conditions. GWRMP compensates the problem of underestimation
of precipitation by MSWEP (10% to 25%), and avoids the risk of the
high dependence of IDW on rain gauges, and improves the accuracy of
spatial and temporal precipitation in large lake areas with sparse
distribution of rain gauges (Pbias limited to 10%). GWRMP improved the
estimation for different rainfall intensities in the Taihu Lake basin,
especially in the mid-level rainfall and above precipitation
frequencies. Compared with IDW and MSWEP, GWRMP is more suitable for
intense precipitation monitoring and storm flood frequency study in the
basin. Therefore, GWRMP is a better choice for spatial and temporal
estimation of precipitation in the Taihu Lake basin. The GWRMP algorithm
can be applied to other regions with unevenly spaced high-density rain
gauges.

Authors: Venclovaite N. D. , Goryacheva L. G. , Greshnyakova V. A. , Efremova N. A. , Shilova I. V.
Published: April 2021

There is a close relationship between intestine and liver, so-called ‘gut liver’ axis, especially in patients suffered from chronic liver diseases with significant degree of fibrosis. Small intestinal bacterial overgrowth and disturbance in the microbiota composition lead to an increase in the permeability of the intestinal epithelium, the development of endotoxinemia, the activation of pro-inflammatory cytokines and, as a consequence, an additional damage to hepatocytes.

Objective. To estimate the incidence of bacterial overgrowth syndrome (BOS) in the small intestine in adolescents with chronic hepatitis C (CHC), to identify the interaction between this syndrome and cytolytic activity, the degree of fibrosis.

Materials and methods. There is a group of 33 patients aged 12—17 years old with CHC. All children underwent a hydrogen breath test with lactulose. The degree of fibrosis was assessed by the results of liver elastography (Fibroscan), cytolytic activity was determined by the level of alanine transaminase in serum.

Results. The frequency of BOS was 81.8% in the study group. As a result of the correlation analysis, no relationship was found between the development of BOS and the degree of cytolytic activity of chronic hepatitis C (criterion χ2= 0.914, p > 0.05). Also, there was no correlation between excessive bacterial contamination and the degree of fibrosis in the liver tissue (criterion χ2= 0.914,p> 0.05).

Conclusion. BOS in children with CHC occurs much more often than in adults. However, no relationship was found between this syndrome and the severity of cytolytic activity, the degree of fibrotic changes in the liver.

Published: April 2021

Insulin-like growth factor 1 (IGF-1) plays an important role in the energy balance of the newborn baby's body, is associated with protein stores, which allows us to consider its level as an indicator of nutritional status.

Objective: to study the value of insulin-like growth factor 1 and basic nutrients in the blood in premature infants in the process of neonatal adaptation.

Materials and methods. Dynamics blood levels of insulin-like growth factor 1 in premature newborns included two trends: decrease (1 group) and increase (2 group). During a pregnancy most mothers of newborns from 1 group had been nonspecific respiratory and urinary-sexual organs’sinfectious diseases, in mothers of newborns from 2 group prevailed disorders which carried high risk of fetal hypoxia. During a neonatal period blood levels of albumen of newborns from 1 group decreased and blood levels of glucose increased; blood levels of nutrients in newborns from 2 group did not change.

Conclusions. Dynamics blood levels of insulin-like growth factor 1 in premature newborns are markers of metabolism’s processes which were originated in fetal stage and continue in the neonatal period.

To the question of the reasons for the activation of the epidemic process of Мeasles at the stage of elimination of infection and the forecast of the situation in the near and long term
Authors: Platonova T. A. , Golubkova A. A. , Smirnova S. S.
Published: April 2021

Introduction. Measles infection in recent years has become particularly relevant in connection with the registration of outbreaks of this disease in various territoriesof the Russian Federation and abroad.

The aim of the study is to characterize the epidemic process of measles in a large industrial city in the near and long term with the use of modern mathematical modeling technologies for making new management decisions on infection control at the elimination stage.

Materials and methods. The research materials were data from statistical reports of measles incidence in Yekaterinburg from 1950 to 2019 (70 years of follow-up), medical documentation of measles cases, population vaccination data (form No. 6 for 2000—2018 and outpatient maps of children under two years of age vaccinated against measles), results of screening for measles IgG ofmedical organizations, data of planned serological monitoringof population immunity to measles in «indicator» groups in the period from 2013 to 2017 and the results of mathematical modeling of measles incidence in different scenarios of its prevention.

Results. Under the influence of vaccination, the epidemic process of measles in Yekaterinburg — a city with a population of 1.5million inhabitants-has undergone significant changes. During the observation period, the incidence decreased to sporadic levels, there was no indigenous measles, drifts from endemic areas had no consequences, the epidemic process was under control. However, outbreaks of 72 cases in 2016 and 90 cases in 2019 have changed our view of measles as a eradicated infection.

Of the factors that led to the spread of infection in the foci, the most significant were the presence of measles-susceptible children and adults, including those previously vaccinated, mainly in the periods remote from vaccination and revaccination, defects in the clinical diagnosis of measlesin the first and subsequent cases, and violations in the organization and conduct of anti-epidemic measures. Conclusion. Based on the data of mathematical modeling of the epidemic process of measles with different combinations of its determinants, for the elimination of infection, it is necessary to ensure vaccination against measles at the age of 1 year and 6 years in 95—97.5%. In vulnerable groups for infection to discuss the introduction of routine revaccination among people up to 50 years of age with an interval of 10 years.
Toxocarosis as a possible cause of gastrointestinal diseases in children
Authors: Utenkova E. O.
Published: April 2021

Toxocarosis is a widespread geohelminthiasis in the world. In the body of children, the eggs of the parasite usually fall with the soil. Larvae enter the bloodstream through the intestinal wall and are carried by blood to various organs, where they cause inflammation and necrosis. The diseaseis characterized by non-specific clinical manifestations, as a result of which the diagnosis is not always timely. In children, toxocarosis often occurs againstthe background of various diseases of the respiratory, cardiovascular and gastrointestinal systems.

The article presents a case of a combined course of gastric ulcer and visceral toxocarosis in a child of 2 years and 4 months. Taking into account the uncharacteristic disease for this age and the absence of risk factors for the development of stomach ulcers in this patient, it is suggested that toxocarosis may cause the development of stomach ulcers in children.

Published: April 2021

Introduction. Asthma and obesity are the most common chronic health disorders
in children. Although heredity plays a significant role in their
development, environmental factors and early exposure have contributed to
the increasing incidence of both disorders in recent decades. The aim of the
study was to estimate asthma prevalence in schoolchildren in Indjija, Srem
District, Serbia, and to investigate differences in nutritional status of
children with asthma as well as differences between their nutritional status
and prescribed asthma medications. Material and Methods. A cross-sectional
retrospective cohort study was conducted at the Primary Health Center in
Indjija. Of all the medical records of children aged 6 - 14 years, a cohort
of children with asthma was formed. The retrospective study evaluated their
nutritional status and the prescribed asthma medications. Results. The
prevalence of asthma in children aged 6 - 14 was 6.9%. Children with asthma
were significantly more overweight and obese (40.5%) than children without
asthma. Boys accounted for 63.7% of children with asthma, with a
statistically significant gender difference. Abnormal nutritional status was
found in 44.3% of children with asthma and boys with asthma were
significantly more obese (23%) compared to girls (7.8%). Overweight and
obese children with asthma were not prescribed significantly more
medications to relieve asthma symptoms than normal-weight children.
Conclusion. The prevalence of asthma among schoolchildren in Indjija was
6.9%. Children with asthma were more likely to be overweight and obese than
children without asthma, whereas boys with asthma were significantly more
obese than girls. No significant differences were found between their
nutritional status and prescribed asthma medications.

Published: April 2021

Introduction. The aim of this study was to determine the prevalence of
microvascular complications in type 1 and type 2 diabetes mellitus patients
in relation to glycated hemoglobin. Material and Methods. This
cross-sectional study analyzed the prevalence of microvascular complications
in patients with diabetes mellitus registered at the Primary Health Center
Banja Luka. Demographic data, duration of diabetes, blood pressure, glycated
hemoglobin, dyslipidemia, type of therapy, presence of retinopathy,
neuropathy and nephropathy were analyzed. Data collection was done from
December 2017 to November 2018. Results. The study included 228 patients,
132 (57.9%) men and 96 (42.1%) women. The most common microvascular
complication was diabetic neuropathy (24.2%). The mean glycated hemoglobin
level in patients with diabetic complications was 7.75 ? 1.66%. Although all
participants with complications had unregulated diabetes mellitus (glycated
hemoglobin > 7%), a statistically significant difference was found in regard
to microalbuminuria (> 30 mg/24 h) and/or proteinuria (> 0.15 g/24 h) and/or
decreased creatinine clearance (< 1.5 ml/sec) and their mean glycated
hemoglobin (p = 0.025), while for other complications (neuropathy and
retinopathy) the same was not confirmed. Multivariate logistic regression
analysis confirmed that microalbuminuria and/or proteinuria and/or decreased
creatinine clearance (odds ratio = 2.174; 95% confidence interval: 1.040 -
4.543; p = 0.039) as well as elevated diastolic blood pressure (odds ratio =
1.09; 95% confidence interval: 1.024 - 1.162; p = 0.007) were factors
associated with glycated hemoglobin > 7%. Conclusion. The most common
microvascular complication in patients with both types of diabetes mellitus
is diabetic neuropathy with a prevalence of 24.2%. The presence of
microalbuminuria and/or proteinuria and/ or decreased creatinine clearance
were associated with glycated hemoglobin > 7% and elevated diastolic blood
pressure.

Published: April 2021

Introduction. In recent years, the number of diabetic patients requiring
cataract surgery has been on the rise. The aim of this study was to examine
the effects of cataract surgery on visual acuity and changes in the central
retinal thickness in diabetic patients with and without retinopathy, in
relation to the duration of the disease, type of therapy, and the level of
glycated hemoglobin and serum lipids. Material and Methods. The prospective
study included 51 eyes of 34 patients divided into three groups.
Preoperatively, all patients underwent best-corrected visual acuity
evaluation with Snellen chart, cataract grading using lens opacities
classification system III, as well as fundus examination and optical
coherence tomography. Postoperative follow-up visits were scheduled after
the first, fourth, sixth, eighth, and twelfth weeks after which the patients
underwent best-corrected visual acuity evaluation and optical coherence
tomography. The obtained values were statistically processed and analyzed in
relation to the duration of the disease, the type of therapy, and the level
of glycated hemoglobin and serum lipids. Results. Of 51 eyes, 5.9% developed
macular edema during the fourth postoperative week with central retinal
thickness > 310 ?m. Subclinical central retinal thickness changes were
registered in all groups with the highest values in group I (diabetics with
retinopathy) in the sixth postoperative week. The average value of central
retinal thickness in group I was 256 ? 11 ?m at baseline and 273 ? 11 ?m in
week 6. The best-corrected visual acuity improved in all groups, without
changes in central retinal thickness. Conclusion. Good visual acuity and
absence of significant changes in macular thickness are helpful when making
the decision to perform cataract surgery in patients with diabetes.
Postoperative follow-up visits should include optical coherence tomography
in addition to standard procedures.

Published: April 2021

Introduction. Tooth color can be represented in a three-dimensional color
system by applying L* (lightness), a* (red-green color tone) and b*
(yellow-blue color tone) coordinates. Clinically significant color
difference, Delta-E, can be expressed in units that are correlated with
visual perception using the International Commission on Illumination L*a*b*
system. The aim of the study was spectrophotometric analysis of the natural
maxillary central incisor color, and to establish any gender-related
differences in lightness, red-green tone, and yellow-blue tone coordinates.
Material and Methods. The study included 80 students (40 male and 40 female,
with an average age of 22 years). The color of the maxillary right central
incisor was determined using an intraoral spectrophotometer and VITAPAN
Classical and VITA 3D-Master color shade guides. Lightness, red-green tone,
and yellow-blue tone values were recorded for each result. The obtained data
were processed by using ?2, Student?s t-test and Mann-Whitney test. Results.
Results showed no statistically significant gender-related difference in
color according to the VITApan Classical and VITA 3D-Master color key. No
difference was found in the lightness of the central maxillary incisor
between genders, or in terms of red-green tone (p = 0.860573). A
statistically significant difference was found when observing the
sex-related yellow-blue tone of the color of the central maxillary incisor.
Conclusion. The analysis of colorimetric parameters of the International
Commission on Illumination L*a*b* system provides useful information about
the tooth color in the examined population, while potentially revealing
differences in lightness, red-green tone and yellow-blue tone between
genders.

Authors: Demir A. , Irfan M.
Published: April 2021

A holmium:yttrium aluminum garnet (Ho:YAG) laser is mainly used in medical surgeries such as tissue ablation and removal of urinary stones. In the present study, a 20 W solid-state 2.08 μm Ho:YAG laser was designed and implemented for lithotripsy applications. Effects of the temporal profile beam of the Ho:YAG laser on stone fragmentation were demonstrated. Moreover, the power supply driver of the xenon flashlamp was implemented with a distinctive trigger circuit at the start of the laser operation. The home-built power driver was customized to deliver a 0.2–3 ms rectangular pulse duration between 1 and 20 Hz frequencies. Laser pulse energies at 5 Hz in response to pumping energy were measured with 3.55% slope efficiency. Similarly, laser pulse energies at 10 Hz were recorded with a slope efficiency of 2.96%. Overall, 1.7% wall-plug (electrical to optical) efficiency was obtained at 5 and 10 Hz laser operations.
Plagiera eller referera vetenskapligt? En studie om vad studenter behöver lära sig för att bli bättre på referathantering
Authors: Hellman Josefin , Thorsten Anja
Published: April 2021

Den här artikeln fokuserar på studenters referathantering i examinerande uppgifter i högre utbildning och vad studenterna behöver urskilja för att utveckla detta kunnande. Dataunderlaget består av intervjuer och studenttexter. Resultatet bygger på två typer av analyser. Genom en fenomenografisk analys framkom fyra kategorier som beskriver kvalitativt skilda sätt att erfara och hantera referatet. Via en variationsteoretisk analys, utifrån skillnaderna mellan kategorierna, påvisades sedan fyra aspekter som kan anses kritiska för att lära sig referathantering. De beskriver att studenter behöver urskilja att A) textens innehåll kan separeras från dess form, B) det finns ett idéinnehåll i hela källtexten och i längre textavsnitt, C) källans idéinnehåll ska fylla en funktion i relation till den egna textens idéinnehåll och D) referathantering placerar in den egna texten i ett vetenskapligt sammanhang. De kritiska aspekterna som framkommit i studien kan användas som underlag för att planera undervisning i akademiskt skrivande i högre utbildning.

Abstract: Russia's Defence Policy and Military Presence in the Caucasus and Central AsiaThese two reports, Security in the Caucasus. Russian policy and military posture and Security in the Caucasus. Russian policy and military posture, analyse and discuss Russia’s security policy and military posture after 2014 in two regions often described as part of Russia’s ‘near abroad’, the Caucasus and Central Asia. The reports find that although both regions are considered as within Russia’s ‘sphere of influence’, the Russian military structure and policy varies significantly. While geared towards crisis management of potential conflicts in Central Asia, the frozen conflicts in the South Caucasus have made Russia set up for regional war.

Using discourse analysis to understand professional music teacher identity
Authors: Jordhus-Lier Anne
Published: April 2021

The purpose of this article is to discuss the use of discourse analysis in order to understand music teachers’ professional identities. This is done by elaborating on the theory and methodology of a study on professional identities of music teachers within the Norwegian municipal school of music and performing arts. Theoretical and methodological perspectives, including research design, analysis, results, validity and ethics, are discussed in the article. An argument in favour of discourse analysis is put forward: that it offers focus on the context, complexity and power relations of the field, as well as providing an understanding of how identities are constructed and negotiated. The use of discourse analysis in the study provided analytical tools which challenged taken-for-granted knowledge, discovered binary discursive oppositions, and unmasked power relations. The study found that teachers construct their identities within a contested discursive field where meanings are attached to the work they perform, as well as to the institutions they represent.

Published: April 2021

Geometry is one of the particular problems for students. Therefore, several methods have been developed to attract students to learn geometry. For undergraduate students, learning geometry through surface visualization is introduced. One topic is studying parametric curves called the hypocycloid curve. This paper presents the generalization of the hypocycloid curve. The curve is known in calculus and usually is not studied further. Therefore, the research's novelty is introducing the spherical coordinate to the equation to obtain new surfaces. Initially, two parameters are indicating the radius of 2 circles governing the curves in the hypocycloid equations. The generalization idea here means that the physical meaning of parameters is not considered allowing any real numbers, including negative values. Hence, many new curves are observed infinitely. After implementing the spherical coordinates to the equations and varying the parameters, various surfaces had been obtained. Additionally, the differential operator was also implemented to have several other new curves and surfaces. The obtained surfaces are useful for learning by creating ornaments. Some examples of ornaments are presented in this paper.

Published: April 2021

The goal of this study is to compare the types of questions between the 2013 Curriculum Mathematics textbooks and the IB Curriculum on quadratic equations. The approach used in this research is a six-dimensional analysis method consisting of: mathematical activity, the difficulty level of the questions, the types of answers expected, the contextual situation, the types of responses, and the stages of the mathematical questions. The data collection technique is conducted by evaluating and explaining the types of questions. The types of questions were obtained from the 2013 Curriculum Mathematics textbook and the IB Curriculum based on a six-dimensional analysis, namely: mathematical activity, question complexity, type of answer, contextual situation, type of response, and mathematical questions. Based on the type, the results of this study show that the questions in the 2013 curriculum mathematics textbooks are more varied than the questions in the IB curriculum mathematics textbooks on the subject of quadratic equations. However, based on the number, there are more questions in the IB curriculum mathematics textbook than the questions in the 2013 curriculum mathematics textbook.
Nature: the cure we've been looking for
Authors:   , Knowles Sarah
Published: April 2021

Nature-based therapy is a therapeutic lens that utilizes nature as a co-therapist. This approach addresses the disconnect between land and people, a disconnect that negatively impacts the mental health of many of those seeking mental health services. Consequently, this approach is now considered an effective treatment for youth and is used as a standalone approach or integrated with cognitive behavioural therapy, gestalt, or group therapy. In either case, this nature-based lens provides a bridge between traditional Indigenous practices and Western psychology. My project highlights various activities and ideas in order to incorporate nature into one’s practice as a therapist, specifically within a northern context. Information regarding benefits, ethical concerns and various types of nature-based therapy will be discussed and guide the development of the manual. The guidebook will assist those interested in nature therapy by creating a place where tangible and realistic ideas for how to incorporate it into practice are located.
Reconversão de áreas industriais e inclusão social? o caso da LX Factory, Lisboa | Reconversion of industrial areas and social inclusion? The case of LX Factory, Lisbon
Authors: Somekh Nadia , Cardoso Thais Luppi
Published: April 2021

Este artigo tem como objeto de estudo o caso da LX Factory, na cidade de Lisboa, Portugal, e apresenta uma questão: é possível que as transformações contemporâneas, incentivadas por políticas culturais, sejam capazes de promover e garantir a inclusão social? A partir da leitura do projeto da LX Factory, foi possível identificar em que circunstâncias essa iniciativa se consolidou e se desenvolveu, assim como apontar como foi tratada a questão da inclusão social, além do possível processo de gentrificação do espaço e do seu entorno. Desse modo, este artigo busca compreender se é possível promover a inclusão social, de forma sustentável, a partir de um projeto de intervenção urbana compartilhado, baseado em uma política cultural. Nessa leitura, considera-se a ideia de que pensar em um espaço público democrático como nova alternativa de trabalho e renda pode ser um critério de inclusão social. Embora a gestão do espaço em questão seja privada, há políticas nacionais e municipais que estimulam o desenvolvimento local. Por meio de uma descrição do projeto da LX Factory, em Lisboa, são apontados a sua origem, seu desenvolvimento, bem como seu impacto no bairro de Alcântara e para a cidade de Lisboa. É possível compreender esse caso icônico como uma referência a ser replicada em outras cidades em transformação? Essa é a indagação que permeia este artigo.
Jesuítas e ensino religioso no Brasil
Authors: Batista Eraldo Leme
Published: April 2021

Neste artigo, abordamos os primórdios da educação religiosa em terras brasileiras, destacando como ametrópole portuguesa realizou as primeiras experiências educacionais no Brasil Colônia mediante açõescatequéticas e educacionais da Companhia de Jesus, ordem religiosa sob o comando da Igreja Católica.Os jesuítas, com apoio incondicional da Coroa portuguesa, desenvolveram hegemonicamente o trabalhoeducacional em terras nativas em um período em que a Igreja buscava se fortalecer. A Companhia deJesus, chefiada por Manuel da Nóbrega, chegou ao solo brasileiro no ano de 1549 com a missão deevangelizar e instruir. Os primeiros ensaios educacionais dos padres jesuítas foram com as criançasindígenas, tendo em conta que os índios adultos se evadiam, rejeitando a aproximação que visava àcatequização. O objetivo do artigo é analisar a educação brasileira no Brasil Colônia no período históricode 1549 a 1759, fase em que os jesuítas desenvolveram suas atividades religiosas e educacionais nopaís, sendo depois expulsos pelo Marquês de Pombal. Entendemos que o primeiro trabalho pedagógico,educacional e de ensino religioso foi realizado sistematicamente na colônia pelos jesuítas, com apoio dogoverno de Portugal, portanto estatal.

O Programa Nacional de Alimentação Escolar–PNAE é responsável pela distribuição de recursos financeiros para alimentação de alunos de escolas públicas no Brasil, garantindo merenda escolar para todos os estudantes matriculados. Este trabalho apresenta como objetivo geral analisar os tipos de gestão da alimentação escolar utilizados pelos municípios brasileiros, tendo como objetivos específicos: Descrever os aspectos introdutórios sobre alimentação escolar, Informar os valores dos repasses enviados aos estados e municípios e o número de beneficiados como o PNAE e Identificar as vantagens e desvantagens de cada tipo de gestão da alimentação escolar. Este é um estudo de revisão bibliográfica, onde foram utilizados sites de busca, como Google Acadêmico e SCIELO, através das palavras-chave: alimentação escolar, gestão, tipos de gestão. Como resultado da pesquisa foi formulado um quadro comparativo com as vantagens e desvantagens dos 4 (quatro) modelos de gestão da alimentação escolar adotados pelos municípios brasileiros. Conclusões: Conclui-se então que devido à extensão territorial do Brasil, uma gestão pode ser melhor empregada do que em outra, pois os problemas e as necessidades são peculiares a cada região, sendo complexo apontar qual a melhor gestão, pois cabe a Entidade Executora analisar qual o modelo que melhor atende a sua realidade e necessidade.
