description: Background:

Cholecystogastric fistulas are a rare complication of chronic biliary disease, characterized by an abnormal communication between the gallbladder and the stomach. This condition can cause symptoms such as abdominal pain, nausea, vomiting, and weight loss. This article presents the clinical case of a male in his 8th decade who was experiencing a typical case of biliary colic. During the surgical procedure, a cholecystogastric fistula was identified, and the management provided by our team resulted in a favorable outcome.

description: A lattice Boltzmann scheme simulating the dynamics of shell models of turbulence is developed. The influence of high order kinetic modes (ghosts) on the dissipative properties of turbulence dynamics is studied. It is analytically found that when ghost fields relax on the same time scale as the hydrodynamic ones, their major effect is a net enhancement of the fluid viscosity. The bare fluid viscosity is recovered by letting ghost fields evolve on a much longer time scale. Analytical results are borne out by high-resolution numerical simulations. These simulations indicate that the hydrodynamic manifold is very robust towards large fluctuations of non hydrodynamic fields.

description: A numerically effective description of the total active reflection coefficient and realized gain are studied for multi-port antennas. Material losses are fully considered. The description is based on operators represented in an entire-domain port-mode basis, i.e., on matrices with favorably small dimensions. Optimal performance is investigated and conditions on optimal excitation and matching are derived. The solution to the combinatorial problem of optimal ports' placement and optimal feeding synthesis is also accomplished. Four examples of various complexity are numerically studied, demonstrating the advantages of the proposed method. The final formulas can easily be implemented in existing electromagnetic simulators using integral equation solver.

title: The Development and Evaluation of a Time-Resolved Fluoroimmunoassay for Lipoprotein (a) in Human Serum
Creators: name: Burling, Keith Anthony
Publisher: name: The Open University
Year: 1995

description: Lipoprotein (a) (Lp(a)) has a complex structure which includes two apolipoproteins, apolipoprotein B (which is also present in other serum lipoproteins) and apolipoprotein (a) (which is unique to Lp(a)). Raised serum concentrations of Lp(a) have been associated with an increased risk of coronary heart disease. Commercially-available Lp(a) assay systems suffer from poor analytical performance. In this study, cell lines secreting anti-Lp(a) antibodies are identified using a series of immunoassay-based screening tests. Monoclonal antibodies developed from these cells lines are used (in conjunction with commercially-available polyclonal anti-Lp(a) antibodies) to develop a two-site time-resolved fluoroimmunoassay for Lp(a) in human serum. This assay format requires one antibody to be immobilised onto the surface of a microtitre plate and a second antibody to be labelled with an element from the lanthanide series (europium) which, under certain reaction conditions, is fluorescent. Protocols for the labelling of polyclonal and monoclonal antibodies with europium are presented in this thesis. Various combinations of anti-Lp(a) antibodies are used in assay development. The combination found to give the best assay performance with the minimum of interference from other biomolecules was:- a monoclonal anti-apo (a) capture antibody with a europium-labelled polyclonal anti-apo B detection antibody. Data obtained during the optimisation of antibody concentrations, sample dilution and reaction times is also presented. In the optimised assay, 200μl of a 1:1000 dilution of serum is incubated with the capture antibody for three hours. Following a wash step, immune complexes are detected fluorimetrically after incubation with a europium-labelled second antibody for two hours. The performance of the assay is compared to that of commercially-available kit assays. The time-resolved fluorescence assay is shown to be more precise and to have a much wider working range (1-1500 mg/L) than the commercial assays. However, data from analysis of samples distributed as part of an external quality control scheme is used to demonstrate the wide inter-assay variability of Lp(a) measurements. Measured Lp(a) concentrations in a series of human serum samples demonstrate the highly skewed distribution previously reported in adult Caucasian populations. No significant differences are observed in the mean serum Lp(a) concentrations of males and females and no correlation could be made between age and serum Lp(a) concentration in the adult population studied. In a limited study, a wide day-to-day percentage variation in serum Lp(a) concentration is demonstrated in one subject.

description: Background: Health apps can improve access to behaviour change interventions. However, the selection of apps is often influenced by factors such as popularity as opposed to evidence-based content. Rapid disengagement is also common. Purpose: To explore how potential users 1) select and 2) engage with health apps in commercial app stores and on curated health app portals. Methods: Semi-structured interviews and a think-aloud approach were used. 18 UK-based adults who were interested in using a health app were recruited online. Participants were asked to verbalise their thoughts whilst searching for a health app of their choice. Data were analysed using the framework approach. The COM-B model and the Theoretical Domains Framework informed the analysis. The study protocol was registered on the Open Science Framework (https://osf.io/jrkd3/). Findings: The following factors influenced the selection of and engagement with health apps: 1) physical capability (e.g. enhancing app literacy skills to reduce the digital divide); 2) psychological capability (e.g. reduced cognitive load); 3) physical opportunity (e.g. low financial cost and tailored content); 4) social opportunity (e.g. social proof and embedded practical support); 5) automatic motivation (e.g. emotional factors and rewards); 6) reflective motivation (e.g. beliefs about the utility of the app). Conclusions: Health organisations that develop app portals may consider targeting the factors identified across the COM-B domains as this could help to increase impact through better selection of apps. The findings will inform the development of web-based interventions that aim to promote the uptake of and engagement with evidence-based health apps.

An Investigation of Parent-Teacher Conferences as a Means of Promoting Better Understanding of Mentally Handicapped Children
Creators: name: Scott, Nellie B.
Publisher: name: American University
Year: 2023

description: Responsibility for the guidance and development of the mentally handicapped child is generally shared by the home and the school. Parent-teacher conferences should be one of the most direct and effective means of building a foundation of understanding and cooperation in discharging this dual obligation to the youngster who does not measure up to a regular school program. However, little can be accomplished and maintained for the child unless the teacher knows how to establish a favorable working relationship with the parent.
Recent Results from 2 pi-zero Photoproduction off the Proton

description: The reaction $γp \to π^0 π^0 p$ has been measured using the TAPS BaF$_2$ calorimeter at the tagged photon facility of the Mainz Microtron accelerator in the beam energy range from threshold up to 820 MeV. Close to threshold, chiral perturbation theory (ChPT) predicts that this channel is significantly enhanced compared to double pion final states with charged pions. The strength is attributed dominantly to pion loops in the 2\Piz{} channel - a finding that opens new prospects for the test of ChPT. Our measurement is the first which is sensitive enough for a conclusive comparison with the ChPT calculation and is in agreement with its prediction. The data are also in agreement with a calculation in the unitary chiral approach. In the second resonance region, a recent model interpretation of new GRAAL data claimed a dominance of the $\Roper \to σN$ reaction process. We present very accurate invariant mass distributions of ${\Piz \Piz}$ and ${\Piz p}$ systems, which are in contrast to the $σN$ intermediate state and which show a dominance of the $Δπ$ intermediate state.

description: We have used the Far Ultraviolet Spectroscopic Explorer to search for OVI 1031.926, 1037.617 A emission in the halos of the edge-on spiral galaxies NGC4631 and NGC891. In NGC4631, we detected OVI in emission toward a soft X-ray bubble above a region containing numerous Halpha arcs and filaments. The line-of-sight component of the motion of the OVI gas appears to match the underlying disk rotation. The observed OVI luminosities can account for 0.2-2% of the total energy input from supernovae (assuming a full OVI emitting halo) and yield mass flux cooling rates between 0.48 and 2.8 M_sun/yr depending on the model used in the derivations. Based on these findings, we believe it is likely that we are seeing cooling, galactic fountain gas. No emission was detected from the halo of NGC891, a galaxy in a direction with considerably high foreground Galactic extinction.

description: Using the dual cone of sums of nonnegative circuits (SONC), we provide a relaxation of the global optimization problem to minimize an exponential sum and, as a special case, a multivariate real polynomial. Our approach builds on two key observations. First, that the dual SONC cone is contained in the primal one. Hence, containment in this cone is a certificate of nonnegativity. Second, we show that membership in the dual cone can be verified by a linear program. We implement the algorithm and present initial experimental results comparing our method to existing approaches.

description: Background: Participation in esports has grown significantly leading to potential concerns regarding the health status of players due to the inherent sedentary nature of playing video games. Purpose: To examine the weight related health status via body mass index (BMI), waist-to-height ratio (WHtR), and body composition (BC), as well as maximal grip strength (MGS) in a sample of esport athletes (EA) living in Germany and Switzerland. Methods: To date, the sample consists of 36 male EA (age: 24.2±3.5 years). Body mass index (BMI), waist-to-height ratio (WHtR), and body composition (BC) using bioimpedance analysis (Tanita RD-545) were assessed. MGS was recorded using a digital hand dynamometer (Saehan DHD-1). Descriptive statistics were compared to established age-matched normative data from the German population. Results: According to BMI, 16.7% (n=6) of the EA were classified as obese, while 16.7% (n=6) and 66.7% (n=24) were classified as overweight and normal weight respectively. Compared to age-matched population data from Germany, the esport players had a higher percentage of obesity (16.7% vs 6.6%) but lower percentage of overweight (16.7% vs 26.0%). From WHtR measurements, 25.0% (n=9) were classified as at an increased health risk while 75% (n=27) were classified as having healthy values. According to body fat percentage, 16.7% (n=6) were over the 25% threshold for overweight. As for MGS, only 15.9% (n=5) had values above their respective age-height matched normative values, with 25% (n=9) of the esport participants being considered "weak" and at an increased risk for health issues. Conclusions: The prevalence of obesity was higher amongst EA compared to values from the general population, however, the prevalence of overweight was much lower, highlighting the diversity of EA health status. Overall, the prevalence of obesity and subaverage MGS suggests EA may be an ideal target group for health promotive efforts. Funding: None.

description: Grounded haptic devices can provide a variety of forces but have limited working volumes. Wearable haptic devices operate over a large volume but are relatively restricted in the types of stimuli they can generate. We propose the concept of docking haptics, in which different types of haptic devices are dynamically docked at run time. This creates a hybrid system, where the potential feedback depends on the user's location. We show a prototype docking haptic workspace, combining a grounded six degree-of-freedom force feedback arm with a hand exoskeleton. We are able to create the sensation of weight on the hand when it is within reach of the grounded device, but away from the grounded device, hand-referenced force feedback is still available. A user study demonstrates that users can successfully discriminate weight when using docking haptics, but not with the exoskeleton alone. Such hybrid systems would be able to change configuration further, for example docking two grounded devices to a hand in order to deliver twice the force, or extend the working volume. We suggest that the docking haptics concept can thus extend the practical utility of haptics in user interfaces.

description: Bond-dependent magnetic interactions can generate exotic phases such as Kitaev spin-liquid states. Experimentally determining the values of bond-dependent interactions is a challenging but crucial problem. Here, I show that each symmetry-allowed nearest-neighbor interaction on triangular and honeycomb lattices has a distinct signature in paramagnetic neutron-diffraction data, and that such data contain sufficient information to determine the spin Hamiltonian unambiguously via unconstrained fits. Moreover, I show that bond-dependent interactions can often be extracted from powder-averaged data. These results facilitate experimental determination of spin Hamiltonians for materials that do not show conventional magnetic ordering.

description: Background: The association between video game genre and esport athlete (EA) health is unknown. EA who compete in sport games may have a different health profile than EA who compete in non-sport games. Purpose: To compare the body composition (BC), and maximal grip strength (MGS) between “sport” EA (SEA) and “non-sport” EA (NSEA). Methods: To date, the sample comprises 16 male SEA (age: 24.1±3.2 years) and 20 male NSEA (age: 24.1±3.8 years). Body mass index (BMI), waist-to-height ratio (WHtR), and body composition (BC) using bioimpedance analysis (Tanita RD-545) were assessed. MGS was recorded using a digital hand dynamometer (Saehan DHD-1). Welch’s t-test and Cohen’s d were used to compare EA groups. Results: NSEA had higher BMI values than SEA (p = 0.06; d = 0.6). WHtR (p = 0.04; d = 0.68), and body fat percentage (p = 0.02; d = 0.75) were also higher amongst NSEA than SEA, with both reaching statistical significance with large effect sizes. No statistical significance was found for MGS (p = 0.1; d = -0.54). Conclusions: Overall, SEA appear healthier than NSEA, however differences between MGS could not be drawn. Further research is needed with more objective fitness assessments and larger sample sizes to establish if health promotive efforts should be directed more strongly towards NSEA.

Magnetohydrodynamic Density Waves in a Composite Disk System of Interstellar Medium and Cosmic-Ray Gas

description: Multi-wavelength observations from radio to soft X-ray bands of large-scale galactic spiral structures offer synthesized and comprehensive views of nearby disk galaxies. In the presence of a massive dark-matter halo, the density-wave dynamics on galactic scales involves the stellar disk, the gas disk of interstellar medium (ISM), the magnetic field, and the cosmic-ray gas (CRG). In this paper, we explore the dynamic and electromagnetic interplay between the magnetized ISM disk and CRG disk so that structural and diagnostic features of optical, infrared, and synchrotron radio-continuum emissions from a spiral galaxy can be physically understood. On timescales of galactic density waves, cosmic rays collectively may be treated as a relativistically hot tenuous gas fluid that is tied to the large-scale mean magnetic field in transverse bulk motions but moves otherwise differently along the magnetic field relative to the ISM. For both fast and slow magnetohydrodynamic (MHD) density waves in a composite disk system of magnetized ISM and CRG, the minute CRG mass density enhancement is phase shifted relative to the enhancement of parallel magnetic field. Owing to an extremely small number of cosmic rays, the large-scale magnetic field enhancement dominates in synchrotron radio-continuum emissions (as if the CRG is almost unperturbed) for spiral structural manifestations. In addition to the fast and slow MHD density waves, there also exists a suprathermal MHD wave mode by which CRG adjusts itself with an effective suprathermal sound speed close to the speed of light c.
On expansion parallax distances for planetary nebulae

description: The distances to individual wind-driven bubbles such as Planetary Nebulae (PNe) can be determined using expansion parallaxes: the angular expansion velocity in the sky is compared to the radial velocity of gas measured spectroscopically. Since the one is a pattern velocity, and the other a matter velocity, these are not necessarily the same. Using the jump conditions for both shocks and ionization fronts, I show that for typical PNe the pattern velocity is 20 to 30% larger than the material velocity, and the derived distances are therefore typically 20 to 30% too low. I present some corrected distances and suggest approaches to be used when deriving distances using expansion parallaxes

title: WHISTLEBLOWING INTERNAL AUDITORS - A CONTRADICTION IN TERMS?
Creators: name: Vinten, Gerald
Publisher: name: The Open University
Year: 1995

description: The topic of whistleblowing is achieving unprecedented prominence in official reports, publications, research, legislation and the media. Some influential voices are suggesting that far from whistleblowing - informing on organizations that commit illegal or unethical acts - being subversive and undesirable, it may in certain circumstances deserve high praise. Inevitably it entails huge risks, and these risks need to be personally and carefully considered. The first part of this thesis examines the case of external audit, a close cousin of internal audit. There should be fewer opportunities for the external auditor to blow the whistle, although such instances are likely to be highly material. There has been much international debate on the role and purpose of external audit, and this has tended to exclude whistleblowing. However there are winds of change, and tightening of legislation and recent ethical guidance suggests that there are occasions when whistleblowing is either required or seriously to be contemplated. Attention then turns to the central theme of internal audit. For practitioners the issue is far from clear-cut, and the Code of Ethics of the Institute of Internal Auditors and its other guidance is found to be ambiguous and even prejudicial to the interests of the individual member. Case studies of internal audit whistleblowing highlight the issues. Participant observation and social audit are explored, since both result in the possession insights that are the substance from which whistleblowing revelations are derived. Generalized examples of whistleblowing are then presented to shed light on the wider context. Disaster situations by their life-threatening nature receive more widespread assent as to their societal value . The extent of legal protection for whistleblowers follows. Finally come criteria for valid forms of whistleblowing, the formulation of codes of ethics for whistleblowers, and suggest the way forward for the internal audit profession

description: The standard model of cosmology with postulated dark energy and dark matter sources may be considered as a fairly successful fitting model to observational data. However, this model leaves the question of the physical origin of these dark components open. Fully relativistic contributions that act like dark energy on large scales and like dark matter on smaller scales can be found through generalization of the standard model by spatially averaging the inhomogeneous Universe within general relativity. The spatially averaged 3+1 Einstein equations are effective balance equations that need a closure condition. Heading for closure we here explore topological constraints. Results are straightforwardly obtained for averaged 2+1 model universes. For the relevant 3+1 case, we employ a method based on the Gauss-Bonnet-Chern theorem generalized to Lorentzian spacetimes and implement a sandwich approach to obtain spatial average properties. The 3+1 topological approach supplies us with a new equation linking evolution of scalar invariants of the expansion tensor to the norm of the Weyl tensor. From this we derive general evolution equations for averaged scalar curvature and kinematical backreaction, and we discuss related evolution equations on this level of the hierarchy of averaged equations. We also discuss the relation between topological properties of cosmological manifolds and dynamical topology change, e.g. as resulting from the formation of black holes.

description: Background: Mental health problems have been clearly identified in medical students. A growing body of literature indicates that physical activity is associated with positive mental health characteristics. Purpose: This study aimed to evaluate physical activity and psychological distress among Moroccan medical students and to analyze the association of levels of physical activity with psychological distress. Methods: 635 participants were included in this cross-sectional study. The International Physical Activity Questionnaire (IPAQ) was used to assess physical activity and the Kessler Psychological Distress Scale (K10) to evaluate the psychological distress. The data obtained were analyzed by Statistical Package for the Social Sciences (SPSS). Results: Among the whole participants, 55.1% were females and 42.6% lived in university campus. The median age was 20.0 [19.0 – 21.0] years. 25,1% of students reported low level of physical activity, with 30.4% in females and 18,8% in males. The overall prevalence of psychological distress was 48,1% and 14,7% experienced severe level. Females had higher levels of psychological distress than males (p<0,001). The multivariate analysis showed significant association between levels of physical activity and psychological distress. Low level of physical activity is associated with a higher risk of psychological distress (OR=2.98; 95% CI: 1,95; 4.54). Conclusions: The prevalence of psychological distress and low physical activity appears to be high and are significantly associated amongst medical students.

Creators: name: Guenther, Liane

Publisher: name: The Health & Fitness Journal of Canada
Year: 2022

description: Background: In Germany, 67% of women and 44% of men aged 18-29 years with low levels of education do not reach the WHO recommendations for physical activity (PA). Online social networks, such as Facebook, are used by 67% of individuals with low levels of education and may therefore be an appropriate channel for delivering PA interventions. This pilot study aims to evaluate the feasibility of a PA intervention delivered via an online social network in a sample of socially disadvantaged young adults. Program Delivery: In this two-armed controlled intervention trial, 160 participants will be recruited either at vocational schools or via Facebook and randomized to an experimental or a waitlisted control group. Vocational school students will be asked to set up their own team of 2-8 Facebook friends. Through rival comparison and self-monitoring, the teams in the intervention arm will be encouraged to walk 10.000 steps per day for two months using Facebook and a linked pedometer app. Evaluation: To estimate the feasibility of the intervention, aspects related to the process of implementation will be tracked. Potential intervention effects on PA will be assessed at baseline, two- and four–month follow-ups via accelerometers and questionnaires in both groups. Conclusions: The current study will help guide the development and implementation of future social media-based PA interventions on a larger scale targeting young socially disadvantaged adults. Funding: This study is part of the dissertation of the first author and not externally funded.

description: The nature of adsorption on platinum in the presence of trifluoromethanesulfonic acid (TFMSA) has been studied in an attempt to understand what factors make TFMSA a superior electrolyte to H(,3)PO(,4) under fuel cell conditions. The study has encompassed both molecular adsorption and ionic adsorption. From the molecular point of view, the adsorption of carbon monoxide has been investigated to determine why CO is the rate controlling species in the reaction of synthetic reformate fuels on platinum. Potentiokinetic and linear potential sweep techniques have been used to follow the adsorption and desorption processes. The study verified that, just as in the case of other acids, CO readily adsorbs on platinum but it is neither oxidized to CO(,2) nor desorbed at any appreciable rate. The rates of oxidation and desorption can be significantly increased by either increasing temperature or electrode potential. The absence of a strong interaction between the anion of TFMSA and the catalyst is believed to be one of the factors responsible for the superior performance of TFMSA. Using cyclic voltammetry the structure of hydrogen adsorption and desorption on platinum has been used as a tool for measuring anion adsorption. The results have shown that the adsorption/desorption structure in TFMSA is identical to the structures of other non-adsorbing acids such as HF or HClO(,4). In contrast, the hydrogen structure in H(,3)PO(,4) is significantly different from those of either TFMSA, HF or HClO(,4). The non-adsorbing nature of TFMSA has been attributed to the presence of a fully fluorinated hydrocarbon structure but when unfluorinated alkanesulfonic acids (C(,1)-C(,3)) were examined, only ethanesulfonic acid showed any indication of surface activity. While the presence of fluorine in the hydrocarbon structure has not been found to be critical at low acid concentrations (< .5N), at higher concentrations, fluorination will probably be necessary.

description: Background: Urban and rural areas experienced rapid developments over the last decade, but it is unclear how youth’s physical activity and screen time have developed across urban and rural areas. Purpose: To investigate youth’s physical activity and screen time trends across urban and rural areas. Methods: We obtained weighted data of three cross-sectional studies of the German nationally representative Motorik-Modul (MoMo) Study at three timepoints between 2003 and 2017 (N=12,161, age=4-17 years). We analyzed trends in self-reported physical activity and screen time domains over time and across four urbanicity levels (rural, small town, medium-sized town, city) using structural equation modeling. Results: A 30.26 minutes/week-decrease in total physical activity was only observed in rural areas. Leisure time physical activity and outdoor play decreased across all levels, with the strongest decline in rural areas (leisure time physical activity: -41.00 minutes/week, outdoor play: -0.54 days/week). Physical education and extracurricular sports increased between 4.74-7.20 minutes/week across all levels. Computer and gaming time increased across all levels except cities, with the strongest increase in rural areas (+36.66 minutes/day). The decline in outdoor play was driven by adolescents, the incline in computer and gaming time by adolescents and girls. Conclusion: Detrimental trends in physical activity and screen time occur at higher rates in rural areas, contributing to the urban-rural health gap. Rural youth should be specifically targeted to tackle decreasing levels of physical activity and increasing levels of screen time. Funding: Federal Ministry of Education and Research (01ER1503).

description: We introduce a theoretical framework to analyze the thermal properties of a recently proposed "excluded volume" model of quarkyonic matter. This entails proposing finite temperature distribution functions and entropy functionals constrained by internal theoretical consistency. We use the formalism developed here to analyze the effect of temperature on the quark onset as a function of baryon density. We find that the baryon density at which the quarkyonic phase emerges decreases only slightly with temperature, an effect produced by large $N_c$. We furthermore find that a finite temperature increases the density of quarks produced. The framework presented here can be used to compute the equation of state of hot and dense quarkyonic matter which is of relevance to neutron star mergers.

description: The energy density associated with Planck length is $ρ_{uv}\propto L_P^{-4}$ while the energy density associated with the Hubble length is $ρ_{ir}\propto L_H^{-4}$ where $L_H=1/H$. The observed value of the dark energy density is quite different from {\it either} of these and is close to the geometric mean of the two: $ρ_{vac}\simeq \sqrt{ρ_{uv} ρ_{ir}}$. It is argued that classical gravity is actually a probe of the vacuum {\it fluctuations} of energy density, rather than the energy density itself. While the globally defined ground state, being an eigenstate of Hamiltonian, will not have any fluctuations, the ground state energy in the finite region of space bounded by the cosmic horizon will exhibit fluctuations $Δρ_{\rm vac}(L_P, L_H)$. When used as a source of gravity, this $Δρ$ should lead to a spacetime with a horizon size $L_H$. This bootstrapping condition leads naturally to an effective dark energy density $Δρ\propto (L_{uv}L_H)^{-2}\propto H^2/G$ which is precisely the observed value. The model requires, either (i) a stochastic fluctuations of vacuum energy which is correlated over about a Hubble time or (ii) a semi- anthropic interpretation. The implications are discussed.

description: В данной работе рассматривается процесс обследования и коррекции фонематического слуха у детей с дизартрией. Описываются методы, используемые логопедами для анализа произносительной стороны речи, включая выявление ошибок и искажений в произношении звуков. Подробно освещаются задания, направленные на оценку способности детей различать и идентифицировать фонемы, а также анализировать звуковой состав слов, включая работу с паронимами и оппозиционными фонемами. Также рассматривается важность формирования артикуляторной моторики и кинестетического восприятия для улучшения фонематического восприятия. Важным аспектом является комплексный подход к коррекционной работе, включающий профилактику и коррекцию нарушений чтения и письма, а также развитие лексико-грамматического строя речи. Работа подчеркивает, что успешная коррекция фонематического слуха требует систематического и многостороннего подхода, направленного на всестороннее развитие речевых навыков у детей с дизартрией, что в конечном итоге способствует их успешной адаптации в обществе.
