La importancia de la obligatoriedad para exigir el derecho a la educación en México
Authors: Benavides-Lara Mario Alberto
Published: October 2020

The present text offers a conceptual analysis about the implications of the Mexican legislation framework as a tool of obligatoriness to advance education as a right.  The central argument of the article is that obligatoriness, beyond being a normative postulate, is a mechanism that allows the enforceability of the right to education, which responds to a specific socio-political context.  However, the way in which the Mexican state has met this demand requires a new level of reflection in which the pedagogical proposals that are to emerge, be committed to be committed with the recognition of difference and diversity that currently seems to be absent.

Published: October 2020

The cellulolytic bacterial flora present in the rumen of Inner Mongolian sheep are thought to have a high degree of cellulose-degrading activity because of their foraging feeding regimen. However, there are no report on the genetic and species composition of the cellulolytic bacterial flora. In this study, cellulolytic bacteria were isolated from the rumen of Inner Mongolian sheep using a combined method of transparent zone and filter paper degradation. Twenty-two strains were identified via morphological, physiological, and biochemical tests. Ten strains were further identified via DNA (G + C) mol%, together with 16S rDNA gene sequencing analysis. Four types of extracellular and total cellulase activities of representative strains were determined. The results demonstrated that the isolates included Butyrivibrio fibrisolvens, Rumincoccus albus, R. flavefaciens, Fibrobacter succinogenes, and Clostridium polysaccharolyticum. A big proportion of cellulolytic Butyrivibrio fibrisolvens was found in the rumen of Inner Mongolian sheep. This was the first study to analyze the cellulolytic bacterial flora in the rumen of foraging Inner Mongolian sheep. These results indicated that the rumen of Inner Mongolian sheep represents an attractive source for cellulolytic microorganisms and enzymes, and the research results have a certain guiding importance for the efficient degradation of cellulosic materials.

Published: October 2020

Tissue paper conversion consists of the transformation of base tissue papers into finished tissue products to meet specific demands. When base tissue paper arrives at the converting line, it already holds different requirements that were met during its manufacture in the paper machine (e.g., grammage, bulk, tensile index, etc.). However, what happens during converting can still influence the performance and quality of the finished products. The current work addresses this topic and aims to evaluate the influence of converting conditions on the final softness. For that, two 5-ply finished tissue products were analyzed using different methodologies for their proper characterization in terms of softness and surface analysis. The analyzed products are composed by the same base tissue papers, but some changes were applied on their settings in the converting line. In particular, the base tissue papers arrangement and the embossing pressure affected the finished products, resulting in one of them being softer and more pleasant to touch, with a global handfeel (HF) value of 75.3 units, and the other revealed to be rougher and less pleasant, with a global handfeel (HF) value of 68.0 units.
Flocculation Behavior of Borax Clayey Tailings in Mono- and Dual- Flocculant Systems: Effect of Tailings Slurry Characteristics and polyDADMAC Type
Authors: Karapinar Nuray
Published: October 2020

The effect of tailings slurry characteristics such as solid ratio and solid particle size both, in mono- and dualflocculant systems, were studied as well as the effect of POLYDADMAC type in dual-flocculant system. Oppositely charged flocculants, a polyacrylamide (PAM)-typed anionic and two poly diallyl-dimethyl-ammonium chloride(polyDADMAC)-typed cationic polymers, were employed for the flocculation. Tailings slurry samples were taken on different dates from the discharge point of Kırka Borax Concentrator. Flocculation performance was characterized by the initial settling rate as well as the residual turbidity of supernatant and the extent of sediment compaction. All tests were performed at the natural pH of the tailings slurry (~pH 9.4) at which borax buffered the suspension. The results showed that an increase in solid load of the tailings slurry results in a dramatic decrease in settling rate of flocculated tailings regardless of flocculant system employed. This can be attributed to the possible change in rheological property of the slurry due to the increasing clay content of the slurry with solid ratio. While the solid ratio has an influence on the settling rate of the flocculated tailings, the amount of slimes determines the optimum dosage of cationic flocculant to obtain clear supernatant in dual-flocculant system. When anionic and cationic flocculants were used in combination, the best synergy was achieved with low weight cationic flocculant. Increasing molecular weight of the cationic flocculant from low to medium resulted in two-fold increase in the required dosage to obtain the same flocculation performance. In dualflocculant system, optimum results were obtained by anionic and cationic flocculant combination at around 0.4 kg/ton and 0.8 kg/ton solid dosages, respectively, indicating 11.7 cm/min of settling rate and 85.7% of transmittance value.

Influence of drought on the photosynthetic apparatus activity, senescence rate, and productivity in wheat plants
Authors:   Institute of Plant Physiology and Genetics, National Academy of Sciences of Ukraine 31/17 Vasylkivska St., Kyiv, 03022, Ukraine, Stasik O.O.
Published: October 2020

Effects of soil drought at flowering stage on the functional state of photosynthetic apparatus and chloroplast enzymatic antioxidant defense systems in flag leaf during reproductive period, and the productivity of winter wheat plants of high-protein Natalka variety and drought-tolerant Podolyanka variety were studied in pot experiment. Until flowering and for the control plants during the entire vegetation, the soil moisture content was maintained at a level of 60—70 % of field capacity (FC). Drought treatment (soil moisture 30 % FC) was applied for 7 days covering flowering—early kernel watery ripe period (BBCH 61—71). After that, watering of plants was resumed to a control level which was maintained until the end of the growing season. The estimation of the chlorophyll and Rubisco content, the chloroplast antioxidant enzymes activity, and the net CO2 assimilation and transpiration rates was carried out on flag leaves. The measurements were taken on the third day of watering cessation (the first day the soil moisture reached 30 % FC, BBCH 61), at the end of the drought period (seventh day at 30 % FC, BBCH 71), and after watering resumed at the medium milk (BBCH 75) and late milk (BBCH 77) stages. The components of plant grain productivity were determined by weighing air-dry material at grain full ripeness. It was revealed, that drought stress during flowering inhibited CO2 assimilation and accelerated induction of senescence processes in wheat plants associated with degradation of photosynthetic apparatus and manifested in quicker ontogenetic drop in chlorophyll and Rubisco contents and loss of leaf photosynthetic activity. This exacerbated the drought impact on the plant organism so that after optimal watering return, the physiological and biochemical parameters were not restored to the values of control plants that were all time under optimal moisture supply. Stress-induced premature senescence reduced the supply of plants with assimilates and ultimately led to a decrease in their grain productivity. Impact of drought on flag leaf photosynthetic activity and especially on senescence induction were much more pronounced in the high-protein wheat variety Natalka with a genetically programmed earlier start of the nitrogen-containing compounds remobilization from leaves than in Podolyanka variety. The drought-tolerant variety Podolyanka keep ability to maintain much higher CO2 assimilation activity during drought period and to preserve photosynthetic apparatus from early induction of senescence due to likely more efficient chloroplast antioxidant defense systems, thereby gaining a better assimilates supply for yield formation.

The mechanisms of low-temperature adaptation of triticale (w Triticosecale Wittm.), an intergeneric hybrid that combining high productivity and frost resistance, are not well understood. In particular, the question remains open about the contribution of secondary metabolites to the functioning of its antioxidant system during the formation of frost resistance. The dynamics of the total content of phenolic compounds, flavonoids, and separately the amount of anthocyanins under cold hardening conditions (6 days at temperature of 2—4 °C) of seedlings of varieties with different frost resistance: Buket and Raritet (winter, high-frost-resistant), and Alexandra (winter, notfrostresistant) and Pidzymok kharkivskiy (facultative, less resistant) were studied. The content of phenolic compounds in non-hardened seedlings of various genotypes differed slightly, only in the Pidzymok kharkivskiy variety was slightly lower compared with other studied genotypes. Hardening caused a slight increase in the total content of phenolic compounds in all studied varieties. The total amount of flavonoids in non-hardened seedlings of various genotypes differed slightly. Six-day hardening led to an increase in the content of flavonoids in the seedlings of all studied varieties by 1.7—1.9 times, with no significant differences between varieties. The content of anthocyanins in the non-hardened seedlings of various varieties was different: it was the highest for the Buket variety, and the lowest for the Pidzymok kharkivskiy variety. During the process of cold hardening, it was increasing and had reached approximately the same values in the varieties Buket, Raritet and Alexandra, however, in the least frost-resistant variety Pidzymok kharkivskiy this index was significantly lower. The conclusion about the contribution of anthocyanins, but not secondary metabolites in general, to the formation of frost resistance of triticale seedlings and the antioxidant defense system at low temperatures was made.

The purpose of this study was to evaluate the effect of the laryngopharyngeal reflux (LPR) on the number of tumourinfiltrating T-lymphocytes in laryngeal cancer (LC). According to the results of pH monitoring, 87 patients with laryngeal tumours were subdivided into three groups: 1st group included patients with LC without LPR; 2nd group comprised LC patients with coexisting LPR, patients with benign neoplasms of the larynx with LPR were enrolled into 3d group. TIME was assessed immunohistochemically by counting T-lymphocytes (CD3+), T-cytotoxic cells (CD8+) and T-regulatory cells (Treg; FOXP3+) number within the tumour, in the peritumour stroma, and in the intact areas of the larynx. It was shown that LPR leads to chronic inflammation and affects TIME of laryngeal carcinomas. LC with coexisting LPR demonstrated a higher inflammatory infiltration of tumour area and intact mucosa. However, no statistically significant differences were found between a number of CD3+- and CD8+-cells in LC of the 1st and 2nd groups. In contrast, LPR was associated with higher number of immunosuppressive Treg-cells within tumour and in intact mucosa that could affect immune tolerance and efficacy of anti-tumour immunity facilitating LC progression.

The paper considers voltage converters as sources of conductive electromagnetic interference (EMI). Some features of the standard measurement method of converters EMI are considered and it is shown that it measures only the total level of noise, which can be the same at completely different relations between the differential and common components of EMI. This leads to inefficient use of means reducing the total converter noise to the permitted level, because the different ratio between the above components of this noise requires different means to reduce them. The paper proposes to supplement the standard noise measurement method by two additional measurements at frequencies where the total noise exceeds the permitted level, using during the first measurement the additional RFI common mode filter which effectively reduces only the common noise, and the additional RFI differential mode filter which effectively reduces only the differential noise during the second measurement. It is shown that these two additional measurements make it possible to determine the differential and common components of the total noise. This, in turn, makes it possible to reduce the total noise to the permitted level at the minimal cost. References 6.

This paper deals with an analysis of impedance-differential protection algorithm applied to locate faults on a double-circuit transmission line. In particular, the study of fault location accuracy for the case of using the relation between currents for negative-sequence not for zero-sequence, as it was presented so far, is provided. It results from the well-known fact that zero-sequence impedances are in practice considered as quite unreliable data. Therefore, one has to limit usage of zero-sequence impedance parameters as much as possible. Such approach was applied in this paper and therefore the use of the additional relation of currents for negative-sequence is under investigation. The fault signals from ATP-EMTP simulation on the sample double-circuit transmission line was applied for evaluating the fault location accuracy. References 8, figures 4, table 1.

An analytical method of calculating the thermal condition of foil windings of lower voltage oil distribution transformers has been developed. At known oil temperatures in the tank, this technique provides the identification of heat-recoil ratios on winding surfaces, taking into account their design features and heat loads, as well as calculating the excess esexcesses of the average temperature of the winding and its most heated point above the oil and over the cooling environment. In order to calculate the excess temperature of the winding over the oil by the method of separating variables using the final cosinus-conversion Fourier obtained the solution of the edge problem for the Poisson equation with heterogeneous boundary conditions on the surfaces of the rectangular section winding with anisotropic properties and with its uneven distribution of losses. In addition, an alternative approach has been developed to determine the thermal state of an axisymmetric transformer model by numerical CFD modeling of the system of equations of motion and continuity of the Navier-Stokes coolant. This allows you to obtain the distribution of the oil velocity field and absolute temperatures, both of the oil in the tank, and of the foil and ball windings of the transformer using the minimum empirical data on the physical properties of the oil and the heat transfer of the tanks. The methods are verified by known experimental data for transformers TM-1000/35 and TM-630/10. References 11, figures 4, tables 2.

Absztrakt:

Bevezetés: A korai életkorban szívsebészeti beavatkozáson
átesett gyermekek fejlődése során fellépő viselkedési diszfunkciók jelentősen
függenek a perioperatív szakban átélt eseményektől. Célkitűzés:
A jelen vizsgálat célja, hogy feltárja a hosszú távú viselkedési változásokat a
szívsebészeti beavatkozáson átesett gyermekek körében, és leírja azokat a
perioperatív állapotokat, melyek befolyásolhatják a későbbi megküzdési
mechanizmusokat. Módszer: 80, szívműtéten átesett és 62
egészséges kontroll adatait elemeztük. A pszichológiai status felmérése a
vizsgálati időszakban a Megküzdési Módok Kérdőív, illetve a Gyermekviselkedési
Kérdőív önértékelő kérdéssorának segítségével, míg a perioperatív adatok
felvétele az intézeti adatbázisból retrospektíven történt.
Eredmények: Az operált gyermekek körében mind a
problémamegoldó, mind az érzelemközpontú megküzdési főskála szignifikánsan
alacsonyabb értékeket mutatott az egészséges kontrollcsoporthoz képest. A
Gyermekviselkedési Kérdőív önértékelő változata sem internalizáció, sem
externalizáció tekintetében nem mutatott szignifikáns eltérést. A hosszú időn át
inkomplett keringéssel rendelkező betegek és a kontrollcsoport között
szignifikáns eltérést figyeltünk meg az érzelemközpontú megküzdés, illetve a
szomatizáció terén, míg az acyanoticus és a kontrollcsoport között a
problémaközpontú megküzdés alskáláin (problémaelemzés, alkalmazkodási képesség).
A többszöri műtét mind az érzelem-, mind a problémaközpontú megküzdés
alacsonyabb fokú aktivációjával összefüggést mutatott, és a hosszú kórházi
tartózkodással együtt egy menekülő-elkerülő magatartásforma kialakulásához
vezetett. Következtetés: Úgy tűnik, hogy a kialakult maladaptív
viselkedési mechanizmusok jellege jelentősen függ az inkomplett keringés
fennállásának időtartamától, a műtétek számától és a kórházi tartózkodás
hosszától. A megküzdési stratégiák mozgósítása legfőképp csökkent érzelem- vagy
problémaközpontú válaszkészségben, illetve a szomatizációs tendenciák és a
menekülő-elkerülő magatartásforma felerősödésében nyilvánul meg. Orv Hetil.

Fearing God and Evil Spirits: The Preaching of Malagasy Shepherds
Authors: Austnaberg Hans
Published: October 2020

This article investigates how so-called “shepherds” (mpiandry) in the Malagasy revival movement (Fifohazana) recognize, identify, and address fears through their preaching in what here are called healing services. The services follow a strict liturgy and allow for homiletical spaces where fears are expressed and addressed. This essay presents a few detailed stories from field material produced from qualitative research interviews and observation of preaching in these services. The specific emphasis in the material reveals how in their preaching the shepherds interpret the problems of life in terms of a fight with evil spirits and the devil. Preaching in the movement transforms and empowers vulnerable and excluded people, it reconciles them with God, and it gives meaning and direction to their day-to-day struggles. The preaching, however, is mainly occupied with individual salvation. The author challenges the movement to find contextually and culturally coherent ways to advocate for justice for the vulnerable and excluded.

A Tutorial on the Use of Differences-in-Differences in Management, Finance, and Accounting
Authors: Schiozer Rafael Felipe , Mourad Frederico Abou , Martins Theo Cotrim
Published: October 2020

ABSTRACT Context: natural experiments or quasi-experiments have become quite popular in management research. The differences-in-differences (DiD) estimator is possibly the workhorse of these techniques. Objective: the goal of this paper is to provide a tutorial that serves as practical guide for researchers considering using natural experiments to make causal inferences. Methods: we discuss the DiD advantages, concerns, and tests of validity. We also provide an application of the technique, in which we discuss the effect of government guarantees on banks’ degree of risk, using the 2008 financial crisis as a natural experiment. The database used, as well as the Stata and the R scripts containing the analyses, are available as online appendices. Conclusion: DiD may be used to tackle endogeneity concerns when treatment assignment is random.
Cluster Analysis in Practice: Dealing with Outliers in Managerial Research
Authors: Lopes Humberto Elias Garcia , Gosling Marlusa de Sevilha
Published: October 2020

ABSTRACT Context: in recent years, cluster analysis has stimulated researchers to explore new ways to understand data behavior. The computational ease of this method and its ability to generate consistent outputs, even in small datasets, explain that to some extent. However, researchers are often mistaken in holding that clustering is a terrain in which anything goes. The literature shows the opposite: they must be careful, especially regarding the effect of outliers on cluster formation. Objective: in this tutorial paper, we contribute to this discussion by presenting four clustering techniques and their respective advantages and disadvantages in the treatment of outliers. Methods: for that, we worked from a managerial dataset and analyzed it using k-means, PAM, DBSCAN, and FCM techniques. Results: our analyzes indicate that researchers have distinct clustering techniques for dealing with outliers accordingly. Conclusion: we concluded that researchers need to have a more diversified repertoire of clustering techniques. After all, this would give them two relevant empirical alternatives: choose the most appropriate technique for their research objectives or adopt a multi-method approach.
A GARCH Tutorial with R

Published: October 2020

ABSTRACT Context: modeling volatility is an advanced technique in financial econometrics, with several applications for academic research. Objective: in this tutorial paper, we will address the topic of volatility modeling in R. We will discuss the underlying logic of GARCH models, their representation and estimation process, along with a descriptive example of a real-world application of volatility modeling. Methods: we use a GARCH model to predict how much time it will take, after the latest crisis, for the Ibovespa index to reach its historical peak once again. The empirical data covers the period between years 2000 and 2020, including the 2009 financial crisis and the current 2020’s episode of the COVID-19 pandemic.

Authors: Irigonhê Alan Tibério Dalpiaz , Moreira Angélica Malman Thomazine , Valle Daniel Almeida do , Santos Mara Lúcia Schmitz Ferreira
Published: October 2020

ABSTRACT Objective: To report a rare case of mucopolysaccharidosis IIIB in a pediatric patient, with emphasis on the description of the clinical manifestations and the early diagnosis. Case description: A 14-year-old male patient, who presented regression of neuropsychomotor development since his three years and six months old, with speech loss and frequent falls, evolving with behavioral changes, with agitation and aggressiveness. Although being diagnosed with autism, there was no response to the established treatment; he was subsequently submitted to metabolic investigation, which lead to the diagnosis of Mucopolysaccharidosis IIIB. Comments: Identifying a metabolic disorder requires connecting multiple signs and symptoms, as well as eliminating other apparent causes. MPS IIIB is a diagnostic challenge, particularly in the early stages and in the absence of a family history of the disease.
Afecto, efecto y realismo en las tres últimas novelas de Ruffato
Authors: Dujisin Matias Rebolledo
Published: October 2020

Resumen Es bien sabido que la poética escritural de Luiz Ruffato consiste en la recuperación del proyecto realista, de su compromiso político y social y de la búsqueda formal de estrategias escriturales que comuniquen la experiencia de su tiempo. Su novela eles eram muitos cavalos es paradigmática de las transformaciones estéticas que buscan responder a las nuevas condiciones de realidad. Sin embargo, en sus últimos textos el autor pareciera dar un vuelco a la experimentación formal que caracterizaba a los textos que le dieron renombre. En las tres novelas analizadas en este artículo el autor asegura transcribir relatos de individuos reales, donde solo participaría como editor; de este modo se aleja del relato fragmentario que explora la potencia significante del lenguaje y construye una narración simple y oralizada. La propuesta de este artículo es enmarcar estos textos dentro de la problemática de los realismos actuales, discutiendo su lugar dentro del proyecto ruffatiano, y planteando como hipótesis el lugar central del esfuerzo de reconstitución de un sujeto fragmentado e inalcanzable, como gesto estético y político en estas novelas.

RESUMO O estudo tem como objetivo compreender a dinâmica estabelecida entre o Sistema de Seleção Unificada e a evasão, mediante as estratégias de escolha do curso, da natureza das motivações e das expectativas em relação ao ensino superior, com estudantes dos bacharelados interdisciplinares de ciência e tecnologia, saúde, humanidades e artes da Universidade Federal da Bahia, ingressantes em 2016. Adotou-se o delineamento de estudo exploratório, com abordagem quantitativa e qualitativa, utilizando questionário on-line desenvolvido unicamente para esse fim, sendo discutidos os resultados provenientes da análise qualitativa. Destaca-se que os estudantes recorrem a diversas estratégias de escolha pelo Sistema de Seleção Unificada, mas utilizam o bacharelado interdisciplinar, majoritariamente, como porta de entrada para os cursos profissionalizantes. Foram encontrados três aspectos motivadores para ingresso na universidade: o suporte social percebido, a motivação pessoal e o mercado de trabalho. Quanto às expectativas, os estudantes esperam usufruir mais da Universidade Federal da Bahia e de seus benefícios do que do curso em si.

Abstract The objective of this study was to investigate the frequency of antibodies to Toxoplasma gondii present in wild mammals that were trap captured in forest fragments in the State of Bahia, northeastern Brazil. A total of 368 individuals (246 rodents, 104 marsupials and 18 bats) were captured using live catch traps. Serum samples were tested using the modified agglutination test, with a cut-off point at 1:25 dilution. The total occurrence of antibodies to T. gondii was 10.6% (39/368), being 16.3% (17/104) in marsupials, 8.5% (21/246) in rodents, and 5.5% (1/18) in bats. Antibody titers varied between 25 and 50 for rodents, between 25 and 400 for marsupials, and were 25 for bats. This is the first report on antibodies to T. gondii in certain rodent species (Thaptomys nigrita, Hylaeamys laticeps, and Cerradomys subflavus), marsupial species (Monodelphis americana, Gracilinanus microtarsus, Gracilinanus agilis and Marmosops incanus), and bats of the genus Rhynchonycteris. The presence of antibodies to T. gondii in wild mammals demonstrates the possibility of these animals as sentinels of toxoplasmosis, especially on regions under high anthropogenic effect.

PURPOSE: to test the effectiveness of dance aerobics to optimize the motor activity and the psychophysical state of female students. METHODS: medical and biological: body weight (kg), BPM and BPD(mmHg), ChSS in a state of rest and the Stange test. All the data obtained by the study were processed by the procedures of descriptive and comparative statistical methods. From the area of the descriptive statistics the following parameters were defined: representative central and dispersive parameters: arithmetic average –; standard deviation –; initial and final measuring. Unpaired test, applied in comparative statistics, was performed in order to compare the arithmetic means of two independent data sets (experimental and control groups). Statistical analysis was performed by applying SPSS statistical software.RESULTS: During the studying, and especially the examination time, students experiencestrong psycho-emotional stress andthephysical state becomes worse. The use of dance aerobics has a positive influence on the psychophysical state of female students and the optimization of their physical activity.CONCLUSIONS:Comparative analysis of data confirmed the effectiveness of dance aerobics tools not only in the absence of negative changes during the examination session, but also improvement of the psychophysical state (state of health by the method of WAM in KG – 3,8 points, EG1 – 4,3 points, EG2 – 4,5 points, ЕG3 – 4.8 points) and the level of somatic health of students (in KG 0.23 ± 0.04 points, ЕG1 8.78 ± 0.50 points, ЕG2 8.77 ± 0.61 points, ЕG3 11, 65 ± 0.55 points)
Kansas Family Physicians Perceptions of Parental Vaccination Hesitancy
Authors: Mills Kale , Nilsen Kari
Published: October 2020

Introduction. In the past few decades, patients expressing the idea that vaccines are unsafe or unneeded have been experienced increasingly by physicians and other healthcare providers. Discussions with patients regarding their reasons for vaccine refusals are important, as it may provide information that can be utilized in an intervention to increase vaccination rates and combat the spread of diseases that are making a resurgence in the United States. The main objective of this study was to explore the perceptions of family physicians as to why parents in Kansas may be vaccine hesitant.

Methods. An electronic survey was distributed to family physicians in the State of Kansas via the University of Kansas School of Medicine-Wichita Family Medicine Research and Data Information Office (FM RADIO). Several aspects of physician perceptions regarding patients’ vaccine hesitancy were measured in this study, including vaccines that are most often refused, reasons for refusing vaccinations, as well as what responses physicians employ when presented with vaccine concerns.

Results. The majority of physicians surveyed have experienced vaccine hesitancy or refusal in their practice, and the human papillomavirus (HPV) and flu vaccines were reported to be the primary vaccines refused for children. In addition, physicians reported frequently employing various practices in response to vaccine refusals, including requiring parents to sign a form (40%) and dismissing families from their practice (1.5%). Physician perceptions on the reasons as to why parents/guardians refuse vaccinations also were measured, and the most common response was that parents possess a fear of long-term complications for their children as a result of vaccines (74%). Additionally, the three most commonly refused vaccines were HPV, influenza, and measles, mumps, and rubella.

Conclusion. Physicians must not only deal with time constraints that vaccine hesitant discussions require, but also must try and implement discussions or interventions suited to the varying reasons why parents/guardians refuse vaccines to convince parents of their safety. The results suggested that vaccine refusals by parents/guardians seemed to be affecting Kansas family physicians’ clinics in more than one way. This study could be a useful tool to help physicians better understand why vaccine refusals occur and be able to combat unwarranted concerns about vaccines.

Of the main types of persistent disorders of the body functions of the disabled due to coronary artery disease, violations of the functions of the cardiovascular system were noted: in 72.0% of cases – moderate, in 26.0% – pronounced, in 1.2% – significantly pronounced; neuromuscular associated with movement (statodynamic) in 41.0% of cases – insignificant, in 8.1% – moderate and in 1.6% – pronounced. Dysfunctions of the endocrine system and metabolism are moderate in 3.6% and insignificant in 23%. Respiratory system dysfunctions in 6% of cases are insignificant, in 2.8% - moderate. Dysfunctions of the blood system and immunity in 2.0% are insignificant and moderate. The total violations in 73.0% of cases are moderate, in 26.0% – pronounced and in 1.6% - significantly pronounced. Among disabled people with higher education, violations of the statodynamic function were observed in 75.0% of cases, moderate, and among those with secondary education – pronounced, dysfunctions of the cardiovascular system in 75.4% of cases were expressed in people with higher education, and among people with secondary education only in 24.6% of cases. Moderate and severe persistent disorders of the cardiovascular system were more often recorded in men. The largest share among the restrictions was I degree of restriction of life activity. More pronounced limitations of the I–II degree of vital activity were noted among men. Limitations of the ability to self-service have a direct strong correlation with disorders of the cardiovascular system and total disorders, a weak direct correlation between limitations to self-service, movement, and work activity with static-dynamic disorders. Restriction to work activity has a direct strong correlation with disorders of the cardiovascular system. There is a direct mean correlation between movement restriction and cardiovascular disorders.
