When conducting experiments on the electric explosion of titanium foil in water, a “strange” radiation was detected, leaving dotted traces on the film. The velocity of the carriers of this radiation was estimated as 20–40 m/s, and their energy, estimated by the Coulomb drag mechanism, turned out to be equal to 700 MeV. Subsequently, it was found that similar traces are formed at various types of high-current arc discharges, both of artificial and natural origin. Many solutions have been proposed to explain the nature of “strange” radiation, but none of them describes the details of the process of formation of dotted traces. We believe that these traces on the film could appear due to the action of charged micron-sized clusters. The possibility of the existence of clusters in the form of a nucleus from a certain number of similarly charged ions enclosed in a spherical shell of water molecules is shown. The force of the Coulomb repulsion of ions is compensated by the compression force of the shell polarized by the inhomogeneous electric field created by the nuclear charge. As the cluster approaches the surface of the film, a cluster with a small charge separates from it. It is accelerated in the electric field of a “large” cluster to energy of about 1 GeV. Having received a recoil momentum, a large cluster moves away from the film, braking in an inhomogeneous electric field, and then “falls” onto it again, and the process is repeated.

The Arctic shelf zone is a very important region in our country due to the huge amounts of hydrocarbons, located there. The exploration of this region is difficult because of the presence of lots of various ice constructions, in particular, ice fields. While carrying out the seismic prospecting works, the reflected waves from the ice field contribute much to the seismograms. It sufficiently complicates the process of further interpretation of the seismograms. Only a few works are devoted to modelling the seismic waves spread through the geological layers of the Arctics in the presence of an ice field as this theme is rather new and needs deeper investigation. In this work we present the results of the investigation of the seismic waves spread in models with an ice field for the 3D case using the grid-characteristic method. The modelling results (wave fields of the velocity distribution and seismograms) allow to identify the reflected waves from the ice field from other waves. In addition, we carried out the comparative analysis of the wave fields and seismograms for the 2D model with an ice field on the surface of the calculated area for the problem description from the work of other authors. The results demonstrate a good qualitative coincidence under different approaches to the solution of the problem.

Published: September 2021

BACKGROUND:Intraocular lens (IOL) dislocation is a rare but serious complication of surgical treatment of patients with cataract. Among the factors contributing to its development, the main ones are pseudoexfoliation syndrome (PEX), high axial myopia, chronic uveitis, history of eye injury and age. There is no universal IOL dislocation correction technique.
PURPOSE:To evaluate the impact on corneal endothelium of two different methods of IOL dislocation correction: IOL repositioning with transscleral suture fixation or IOL exchange to iris-claw one.
MATERIALS AND METHODS:Within the study, 78 patients were examined and operated. All patients were divided into two groups: in the first group, IOL was repositioned with transscleral suture fixation, and in the second group IOL was exchanged to iris-claw IOL. Groups were equal by gender and age. Key estimated indicators were endothelial cell density and coefficient of variation reflecting the degree of polymegatism.
RESULTS:Endothelial cell density was significantly lower both before surgery and at any term after it, in the group with IOL exchange, and coefficient of variation was significantly higher in the group with IOL exchange throughout this study.
CONCLUSION:The choice of technique for IOL dislocation correction is the basis of success in surgical treatment. Certain preoperative examination data should be definitely considered, including the degree of dislocation, IOL type, IOP level, endothelial cell density and presence of concomitant ocular conditions.

Policing the Poachers in a Western State: Game Wardens and the Use of Discretion
Authors: Eliason Stephen L.
Published: September 2021

Game wardens are specialized law enforcement officers responsible for enforcing hunting and fishing laws designed to protect wildlife resources. While performing their duties they encounter a variety of wrongdoers that range from first time offenders to those who are chronic violators of the law. Little research exists on the use of discretion by wildlife law enforcement officers, or their attitudes toward offenders. This study took a qualitative approach to data collection and examined the use of discretion by game wardens in Montana and their perceptions of habitual poachers. Factors that were associated with the use of discretion included intent of the violator, seriousness of the offense, and age of the violator. The majority of wardens in the study expressed negative opinions toward violators that were chronic offenders. Findings contribute to our understanding of law enforcement attitudes and decision making.
A STUDY ON THE CAUSES OF INTERNATIONAL ANTI-CORRUPTION COOPERATION BETWEEN CHINA AND SOUTHEAST ASIAN COUNTRIES UNDER THE BELT AND ROAD INITIATIVE
Authors:   Jilin University, L. Sun , D. Zheng ,   Jilin University
Published: September 2021

With the continuous expansion of China’s outward direct investment in countries along the «Maritime Silk Road», the external environment faced by China’s outward direct investment has become increasingly complex. The impact of corruption and government quality has become more prominent. From 2014 to 2019, the corruption index and institutional distance had a significant impact on China’s outward direct investment in the ten ASEAN countries along the Maritime Silk Road and the quality of their governments. The complex situation presented by the cases of the ten ASEAN countries shows that it is difficult to fully analyze the relationship between government quality and direct investment by a single variable such as a corruption index or an institutional distance. It is necessary to introduce a comprehensive analy-sis of multiple factors, such as cultural distance, political stability, and bilateral rela-tions. In view of this, China should strengthen the «Maritime Silk Road» construction corruption risk assessment, create a risk control mechanism and provide more re-gional public products that contribute to sustainable economic development and trade cooperation between countries along the «Maritime Silk Road».

Authors: Tandon Nikhil , Paul Rajesh , Kwatra Gagandeep
Published: September 2021

Background: The study aimed to compare oral versus topical combination of glucosamine sulphate and diacerein in patients of grade 2 Osteoarthritis.

Methods: This was a prospective study of 70 patients with grade 2 osteoarthritis knee, randomly divided into 2 groups of 35 each. The first group was given oral 1500mg of glucosamine and 100mg of diacerein per day and second group was given topical preparation of 10% w/w glucosamine sulphate and 1% w/w diacerein to be applied twice. Both the groups were followed up at 1, 3, 6 and 12 weeks. At each follow up, Visual Analog Scale (VAS) and Lequesne et al scores were used as efficacy parameters. C-Reactive Protein (CRP) level was measured in the beginning and at the end of 12 weeks.

Results: Both the groups showed improvement in pain and joint function as depicted by VAS score and Lequesne index however the difference was not statistically significant. The decrease in CRP value was significant in oral group (p value<0.001) but not in topical group (p value of 0.047). Paracetamol demand was slightly higher in topical group however the difference was not significant.

Conclusions: Glucosamine sulphate and diacerein combination are effective in improving pain, stiffness and function in patients of grade 2 osteoarthritis knee. However, the efficacy of glucosamine sulphate and diacerein combination- oral as well as topical, in improving pain and stiffness is similar- there is no superiority of one over the other.

Published: September 2021

Phacoemulsification is a variant of extracapsular cataract extraction surgery which is the gold standard treatment modality for cataract surgery nowadays. The common nucleotomy techniques of phacoemulsification are divide and conquer, stop and chop and phaco chop.

Aim of this studyto compare different techniques of nucleotomy during phacoemulsification with respect to corneal endothelial cell loss, central corneal thickness (CCT) and comment on their merits and demerits.

60 patients undergoing cataract surgery by phacoemulsification were randomly divided into three groups of 20 each (Group A, B and C) who underwent nucleotomy by divide and conquer, stop and chop and phaco chop technique respectively. The preoperative endothelial cell density and central corneal thickness were recorded using Topcon SP3000P non-contrast specular microscope. All patients were followed up at 1, 4 and 12week after surgery and evaluated for vision, slit lamp examination, endothelial cell count and central corneal thickness.

The age group of patients studied was 50-80 years, where maximum number of patients were in 51-60 years age group. Out of 60 patients, most common morphological type of cataract was nuclear (40%) cataract followed by cortico-nuclear (36.67%) cataract. After 1 week of surgery, drop in endothelial cell density was 7.06% in Group A, 6.49% in Group B and 6.84% in Group C patients. A further slight decrease in endothelial cell count was recorded during 4week and on final follow up visit at 12 weeks after cataract surgery, there was an endothelial cell loss of 9.51%, 10.9% and 11% in Group A, B and C respectively. The central corneal thickness at 1postoperative week increased by 2.75%, 2.35% and 2.20% in group A, B and C respectively. Further evaluation of CCT at 4and 12 week after surgery showed the values to be almost same as preoperative values. The rate of complications, which mainly included postoperative keratitis, mild anterior uveitis and cystoid macular edema, were found to be almost the same in all the three study groups.

All the three nucleotomy techniques of phacoemulsification i.e divide and conquer, stop and chop and phaco chop are equally efficacious in terms of CCT changes, endothelial cell loss and complications rate in the hands of an experienced surgeon.
Factors affecting non-compliance to spectacle wear in children aged six years and below with refractive errors: A hospital based cross-sectional study in India
Authors: Kankonkar Prajoth , Pai Sharvani
Published: September 2021

Uncorrected refractive errors (RE) are the most common cause of preventable visual Impairment (VI) in children, which if not treated in time can lead to amblyopia. VI in early childhood interferes with their overall development affecting their future opportunities in life. Spectacles remain the most popular and effective method for correction of RE. Children unlike adults, often don’t understand the need for wearing spectacles, thus prescribing spectacles in children becomes difficult.

Aim of this study was to find out proportion of spectacle wear non-compliance in children aged six years and below and identify factors associated with it.

The study was conducted among 115 children aged six years and below with refractive errors who were prescribed spectacle correction. Children were selected using simple random sampling.

Multivariate logistic regression was used to identify independent factors associated with spectacle wear non-compliance.

Proportion of spectacle wear non-compliance was 53.04%. Children with spectacle wear non-compliance were more likely to: belong to age of two to four years (AOR = 4.3; 95%CI: 1.3-14.3); have mother with up-to primary school education (AOR = 3.7; 95%CI: 1.2-11.7); have anisometropia (AOR = 11.1; 95%CI: 3.4-36.7). Statistically significant association was observed between spectacle wear non-compliance and child’s age, mother’s education, anisometropia, astigmatism, manifest squint, intolerance to glasses, glasses lost, glasses broken, concerned teasing and cost issues.

Children less than four years of age; with anisometropia and those whose mothers had up-to primary school education were more likely to be non-compliant to spectacle wear.

Published: September 2021

The proposed new method of measuring angle of anterior chamber is an effective method of measuring the angles. Identification of narrow anterior chamber angle is important for glaucoma screening and prophylactic treatment prevents acute angle closure glaucoma event.

Aim of this study wasto measure the angle of anterior chamber using Topcon spectral domain optical coherence tomography (SD OCT).

In this cross-sectional study 120 normal subjects above the age of 40 years were enrolled. The study was done at the tertiary health care center of central Indian. All volunteers had visual acuity of at least 6/9 with no ocular diseases. Using OCT the angle opening distance (AOD-500), trabecular–iris angle (TIA) and trabecular-iris space area (TISA-500) were measured.

In this study the mean AOD was 0.430 µm in nasal and 0.433 µm in temporal quadrant. The mean TISA in nasal was 0.405 µm and temporal quadrant was 0.408 µm. While the mean trabecular iris angle (TIA) was 26.9° in nasal and 26.01° in temporal quadrant.

The study proved that the proposed method of measuring AOD, TISA, TIA is the effective method as the Topcon-2000 OCT does not have any inbuilt software like that of other ASOCT machines.

: The present study was carried out with objectives to evaluate the safety profile of Nd-YAG Laser Capsulotomy mainly in terms of rise in intraocular pressure (IOP) and other intra as well as post-operative complications.

This prospective observational study was carried out with prior Institutional Ethics Committee (IEC) approval and written informed consent from the participants at Ophthalmology Outpatients Department (OPD) of a tertiary care teaching hospital of western India, for the duration of two years from Oct’2015 to Sept’2017.

A detailed ocular, systemic, family history was taken of all the enrolled patients with pre- and post-procedure evaluation of IOP by Goldman’s Applanation Tonometry, Slit lamp examination and Fundus examination by direct and indirect ophthalmoscopy. Capsulotomy was done using VISULAS YAG III laser of Zeiss company.

The data was entered and tabulated in Microsoft Excel 2007 and analyzed. Data was analyzed by frequency distribution. The ‘p’ value was determined to finally evaluate and P <0.05 was considered as statistically significant.

Acute transient rise of IOP up to 5mmHg or more (P value <0.001) was found in Nine cases which is highly significant compared with pre-procedural stage. Intraocular lens pitting was observed in Four cases. Cystoid macular edema was found in one case. Two patients developed mild iritis.

Nd-YAG laser capsulotomy is an easy, practical modality to treat posterior capsular opacities, but is not a completely innocuous procedure.

Nd-YAG laser capsulotomy is an easy, practical modality to treat posterior capsular opacities, but is not a completely innocuous procedure. Due precautions should be taken in pre- and post-procedural stages including medications, thorough counselling, proper focusing and steady fixation of the patients to minimise the complication.
El problema de los contrafácticos en la semántica de Davidson

Discuto la semántica de las oraciones de acción de Davidson para argumentar que no tiene elementos suficientes para analizar contrafácticos. Presento dos críticas. En la primera, sostengo que dada la ontología del autor acerca de las acciones, resulta imposible considerar la misma acción en circunstancias contrafácticas. En la segunda, argumento que el carácter descriptivo de las oraciones impide que un hablante pueda extrapolar la semántica davidsoniana de oraciones que este conoce a oraciones de acción contrafácticas.

The reduction of dissolved oxygen (DO) in water is associated with the effect of climate change. The lack of oxygen in water bodies directly affects the biological species present in different shallow water bodies such as swamps and wetlands, as well as in aquaculture processes. An optimal value in the DO concentration favors the reproduction of these biological species present in both artificial and natural environments. For this, various equipment has been developed to favor the increase of DO in the water to acceptable values. However, some of these systems are expensive, energy inefficient, and noisy which generate adverse impacts in aquatic ecosystems due to perturbances in the water. This study measures the efficiency (KgO2·kWh-1) of introducing DO into the water using a paddle wheel aerator system at low RPMs destined for shallow bodies of water. Tests were performed on anoxic water samples using aerators with 6, 12, and 24 paddles at the laboratory level. By increasing the voltage (6, 9, and 12V), the RPMs applied to each device through a geared motor is also increased. The results show a higher DO transfer rate in the 1 and 5 mg of O2·L-1 range. The best configuration concerning energy consumption worked at low RPMs using the 6-paddle wheel aerator at 6V. This establishes that, in addition to the management of low revolutions, the use of a smaller number of wheels favors an increase in efficiency during the DO restoration process in shallow water bodies.

In this work, Peng-Robinson EOS (equation of state) was chosen to represent liquid phase behavior. Then, regarding the three acids, Lauric, Palmitic and Stearic, bulk modulus coefficients were calculated in three values of pressures (0.1, 1.0 and 2.0 GPa) and a range of temperature of 350-450 K. According to the literature, results for carbon dioxide, bulk modulus in the liquid phase is in the same line for the one in the solid phase considering the temperature dimension. Based on it, in this work, the bulk modulus was estimated at three temperatures for three acids in solid-phase by extrapolating the results in the liquid phase. Despite there are no experimental data available in the literature, these results seem to be consistent with the thermodynamic constraints, and useful discussions were provided.

El aumento de la población mundial ha tenido como consecuencia el crecimiento de la industria de la construcción. Lo anterior, implica la explotación de recursos naturales no renovables y por ende un mayor impacto ambiental por la contaminación del suelo, el agua y el aire. Así, el desarrollo sostenible se ha convertido en una prioridad en la industria, por ejemplo, por medio de la incorporación de residuos en la cadena productiva. El acero puede producirse por dos métodos: el alto horno (se funden minerales de hierro) y el horno de arco eléctrico (se funde chatarra metálica reciclada). En este último, el proceso más utilizado en Colombia, se forma la escoria horno de arco eléctrico (EHAE). Este residuo representa una oportunidad de aprovechamiento en la construcción. Varias investigaciones han estudiado el uso de este material como agregado y como materia prima del cemento. Así mismo, su utilización como sustituto de material granular en la construcción de terraplenes, bases, subbases y capas de rodadura, siendo en el área de pavimentos donde mayor aplicación puede darse a la escoria. Este trabajo tiene como objetivo realizar una revisión actualizada del estado del arte sobre el uso de la EHAE en la construcción, para promover la implementación correcta y segura de este residuo y aportar a la sostenibilidad de la industria siderúrgica.
Design of a Groundwater Level Monitoring System Based on Internet of Things and Image Recognition
Authors: Bo Qiuyu , Cheng Wuqun
Published: September 2021

This paper designs an intelligent groundwater level monitoring system based on image recognition and Internet of things (IoT). Image recognition technology was employed to process the water level image, and determine the water level line. The IoT was adopted to transmit the collected multimedia data accurately to the monitoring end, thereby realizing the automatic remote monitoring of real-time water level. After analyzing the image recognition technology and the key algorithm of water level recognition, the authors designed the whole process of groundwater level monitoring with two modules: water level monitoring base station, and remote monitoring management center. The water level monitoring base station is embedded with a data acquisition module to periodically collect data, including water level, videos, and images. The collected data were sent to the remote monitoring management center through the cellular network. Then, flood or low water warning could be determined according to the historical data. Finally, the proposed groundwater level monitoring system was tested. The results show that the system not only solves the problem of measurement accuracy, but also improves the work efficiency.
A Hybrid Method Based on LSTM and Optimized SVM for Diagnosis of Novel Coronavirus (COVID-19)
Authors: Challab Jamal Mhawesh , Mardukhi Farhad
Published: September 2021

The coronavirus disease of 2019 (COVID-19), a unique Coronavirus strain, has created a chaotic situation, negatively impacting the number of deaths and people's lives globally. The daily increase in COVID-19 instances is due to a lack of and restricted availability of detection techniques for determining the disease's presence. Therefore, detecting positive results as soon as feasible is important to preventing the spread of this epidemic and treating infected people as soon as possible. As a result of these constraints, the demand for clinical decision-making systems based on predictive algorithms has increased. The article describes a recurrent neural network (RNN) for identifying Coronavirus (COVID-19) and tries to improve the detection method. Different machine learning methodologies, such as Support Vector Machines (SVMs), were used to create a detection system with a deep learning algorithm called Long Short Term Memory (LSTM). The research describes a method for detecting COVID-19 in tagged CT images of patients. Various common picture features, such as central moments, Gabor wavelets, and GLCM-related features, are discussed. Ant colony optimization-ant lion optimization (ACO-ALO) is used to select optimum subsets of SVM parameters. The results show that SVM parameters such as penalty and kernel parameters have a positive effect on SVM model correctness and complexity. Besides, the findings revealed that the proposed method may be employed as a system of aid to diagnose COVID-19 disease. The findings uncover that the suggested strategy has promising behavior in terms of increasing classification accuracies as well as optimal feature selection. Promisingly, the presented strategy can be regarded as a useful clinical decision-making tool for clinicians.
About the origin of the acrocentric part of non-acrocentric satellited chromosomes in humans
Authors:   Friedrich Schiller University Jena, Abdulazeez Mohammed , Kankel Stefanie ,   Friedrich Schiller University Jena, Liehr Thomas ,   Friedrich Schiller University Jena
Published: September 2021

Variants in size of the acrocentric short arms (acro-ps) are normally not reported and considered as chromosomal heteromorphisms (CHMs) without any influence on the carrier’s phenotype. However, if acro-ps are translocated to ends of A-chromosomes (i.e. human chromosomes 1-22 and X or Y), those rearrangements are studied in more detail. The aim of the study: Here we characterized 11 healthy carriers of a non-acrocentric satellited chromosomes der(A)t(A;acro)(pter or qter;p1?1.2) to determine the frequency of chromosome 15p and 22p in such rearrangements. Materials and methods: 11 carriers of one (10 cases) or two (1 case) der(A)t(A;acro) were identified during routine cytogenetic analyses. They were originally referred due to infertility or due to a mentally retarded child with otherwise abnormal karyotype. Here derivative chromosomes were studied by fluorescence in situ hybridization applying probes D15Z1 (specific for 15p11.2) and D22Z4 (specific for 22p11.2). As there are no DNA-sequences available for 13p11.2, 14p11.2 and 21p11.2 these regions could not be tested. Results: D15Z1 sequences were identified in 1 out of 12 derivatives der(A)t(A;acro). D22Z1 could not be detected in any of the 11 remainder derivatives. However, only 3 of the 12 der(A)t(A;acro) had acro-ps large enough to potentially comprise sub-band p11.2. Conclusion: In contrast to der(Y)t(Y;acro)(q12;p1?1.2), where in at least 65% of the cases the acro-p part contains D15Z1 sequences, here it could be shown that in der(A)t(A;acro) 15p involvement can be substantiated much less frequently. Also, in none of the two groups D22Z4-sequences were detected in acro-p-parts yet. Besides, breakpoint of acro-pparts in der(A)t(A;acro) seem to be in ~75% of the cases distal from p11.2.
The relationship between polymorphism rs12449964 of the phosphatidylethanolamine- N-methyltransferase gene and hypertriglyceridemia and obesity in patients with type 2 diabetes
Authors:   Kursk State Medical University, Azarova Iuliia E.
Published: September 2021

Phosphatidylethanolamine N-methyltransferase (PEMT) is the enzyme of lipid metabolism that catalyzes the conversion of phosphatidylethanolamine to phosphatidylcholine in a series of three methylation reactions. Low activity of the enzyme can increase the availability of phosphatidic acid for triacylglycerol synthesis and thus favor obesity, one of the most important risk factors for type 2 diabetes (T2D). The aim of the study: To study the relationship of the rs12449964 (C>T) in the regulatory region of the PEMT (phosphatidylethanolamine-N-methyltransferase) gene with blood plasma triglycerides, as well as the risk of obesity and T2D in population of Central Russia. Materials and methods: The study included 2060 unrelated individuals of Slavic origin, including 1024 patients with T2D and 1036 healthy volunteers. Genotyping of PEMT gene polymorphism (C>T, rs12449964) was performed by laser desorption / ionization time-of-flight mass spectrometry using the MassArray Analyzer 4 platform (Agena Bioscience). SNPStats online program was used for statistical analysis of the obtained data. Results: Linear regression analysis did not reveal an association of rs12449964 of the PEMT gene with a risk of developing T2D regardless of body mass index (P>0,05). However, the T/T genotype of the studied SNP is associated with an increased risk of obesity in patients with type 2 diabetes (OR 1.66; 95% CI 1.11-2.46; P = 0.011, adjusted for sex and age, recessive model). In addition, carriage of the T/T genotype was associated with a higher level of triacylglycerols in the blood plasma of patients with T2D, both in the presence of obesity and without it (P<0.05). According to GTEx Portal, the rs12449964T allele is associated with decreased PEMT expression in various tissues. Conclusion: The study revealed for the first time the association of rs12449964 of the PEMT gene with hypertriglyceridemia and an increased risk of obesity in patients with T2D, which may be due to the low transcriptional activity of the phosphatidylethanolamine- N-methyltransferase gene in carriers of the alternative allele of the studied SNP.
PSZICHOMETRIAI KREATIVITÁS ALAKULÁSA GIMNAZISTÁK KÖRÉBEN VÉGZETT NÉGY ÉV IDŐTARTAMÚ LONGITUDINÁLIS VIZSGÁLATBAN
Authors: Mező Katalin
Published: September 2021

E tanulmányban a pszichometriai kreativitástesztek teszt-reteszt megbízhatóságát és intelligenciával való kapcsolatát elemezzük. Minta: n=107 (66 férfi, 41 nő) gimnazista. Módszer: 2011-ben felvettük a verbális Szokatlan használat és a figurális Körök kreativitásteszteket és (kiegészítő vizsgálatként) az APM intelligenciatesztet, majd 2014-ben e vizsgálatokat megismételtük. Eredmények:a kreativitásvizsgáló eljárások esetében hasonlóan mérsékelt együttjárásokat tapasztaltunk (rs=0,30-0,51), mint az intelligencia-vizsgálat esetében (r=0,53). Az elővizsgálatok során magasabb pontszámokat szerző tanulók inkább érnek el nagyobb pontszámkülönbséget az elő-és utótesztben, mint az elővizsgálatban alacsonyabb pontszámot szerző tanulók (rs=0,28-0,57).

Authors: Demeter Kármen , Szabó Kinga
Published: September 2021

Vizsgálatunkban az egyes agresszivitásformák és a kisiskolások csoportban elfoglalt szociometriai státusza közötti összefüggéseket céloztuk meg, figyelembe véve ezen tényezők hatását az agresszív gyerekek társaikkal szemben megfogalmazott gondolatainak ellenséges voltára. Minta: 321 erdélyi kisiskolást (M = 10,25 év, SD = 0,71) vizsgáltunk, akik közül 61,4% román és 36,8% magyar etnikumú diák volt.Módszer: eszközeink segítségével az esetlegesen megjelenő agresszivitás formáját, a gyerekek osztályban elfoglalt szociometriai státuszát, illetve a társakkal szembeni ellenséges gondolatok minőségét mértük. Eredmények: a nemi különbségeknek és szociometriai státusznak hatása van az agresszív viselkedés típusára. Az eredmények a prevenció és intervenció területén alkalmazhatók.
FEJLESZTŐPROGRAMOK HATÁSVIZSGÁLATÁNAK MATEMATIKAI STATISZTIKAI ALAPFOGALMAI
Authors: Máth János , Mező Ferenc , Abari Kálmán , Mező Katalin
Published: September 2021

Pedagógusok, óvodapedagógusok, gyógypedagógusok, fejlesztőpedagógusok, pszichológusok – egy csokorra való azon szakemberek köréből, akik képesség- és/vagy  személyiségfejlesztő programokat hozhatnak létre, valósíthatnak meg. E programokkal szemben elvárható azonban, hogy az általuk ígért fejlesztőhatást akár matematikai statisztikai elemzéssel is alá lehessen támasztani. Ez azonban nem mindig történik meg – ennek hátterében pedig részben a matematikai statisztikai fogalmi és módszertani hiányosságok, valamint a drága statisztikai szoftverek állnak. E tanulmány a különleges bánásmódot igénylők számára készült fejlesztőprogramok hatásvizsgálatának matematikai statisztikai elemzéséhez nyújt elméleti összefoglalót.

Published: September 2021

Cikkünkben a központosított oktatáshoz kapcsolódva egy új oktatási azonosító bevezetésének lehetőségét szeretnénk bemutatni. A megoldásunkhoz korábbi kutatásaink eredményei szolgáltatták az alapot. Célunk nem kizárólagosan elvetni a már meglévő törekvéseket, mint például az eduID szolgáltatás, hanem elsőként egy már működő infrastruktúra bevonásának lehetőségét megvizsgálni, másodsorban pedig egyfajta továbbfejlesztési irányt mutatni az említett eduID tekintetében. Az elkészített tanulmányunkban megfogalmazott hipotézisek alátámasztását egy felméréssel kívánjuk alátámasztani, mely nagymértékben igazolja is feltételezéseinket.
FACTORS OF PARENTAL INVOLVEMENT IN RELATION TO CHILDREN’S BEHAVIORAL SYMPTOMS
Authors: Kathyné Mogyoróssy Anita , Nagy Erika Beáta
Published: September 2021

In our study, the features of contact between parents and teachers and the particular patterns they take were examined in connection with children’s behavioral symptoms. With cluster analysis, seven clearly analyzable patterns of contact were identified, the two most frequent of which (unifacial and formal) do not favor problem solving, nor provide parental satisfaction.
   Two patterns (flexible and adaptive) proved to be the most satisfying and the most effective. Children’s symptoms (social problems, anxiety, somatization, attention deficit, deviant behavior, aggressivity) are significantly related to the quality of parent-teacher contact. In the case of the less favorable and less effective contact forms, parents report more behavioral symptoms, while in the case of the flexible, adaptive, emotionally satisfying, and effective problem-solving contact forms, there are fewer symptoms. These results draw attention to important tasks on many levels: to work out operable patterns of parent-teacher contact, to better understand the role and tasks of teacher training, and the need to involve experts to assist in developing parent-teacher contact, which is also indispensable in terms of helping and developing children and their mental health.
PÁN PÉTEREK? – AVAGY LÉTEZIK-E A KAPUNYITÁSI PÁNIK A SZAKKÉPZÉSBŐL KIKERÜLŐ FIATALOKNÁL?
Authors: Nagyné Kricsfalussy Anna
Published: September 2021

A tanulmány a Pán Péter Szindrómát, valamint a Kapunyitási Pánikot, az utóbbi évtized közkedvelt kifejezéseit és jelenségeit vizsgálja a felnőttkorba lépő, szakképzésből kikerülő fiatalok körében. Központi kérdései: Miért alakulhatott ki? Miért most? Létezik e valóban, vagy csak az elkerülési stratégiák egyik válfajáról van szó? Milyen jelenségek együttese okozza a kialakulását? Vannak- e életkori sajátosságok, amik hajlamosító tényezőkké válhatnak? Vannak-e nemi különbségek a jelenség megjelenésénél? A kérdések megválaszolásával próbálom igazolni, hogy Pán Péter szindróma helyett inkább egy speciális, életciklus váltás okozta krízis állapotról beszélhetünk.
OLVASÁSI KÉSZSÉG VIZSGÁLATA AFÁZIÁS BETEGEKNÉL A HÁROMUTAS OLVASÁSVIZSGÁLÓ TESZTTEL
Authors: Dankovics Natália , Mokuolu Tímea , Pelyvás Károlyné .
Published: September 2021

Az afázia, a nyelvi képesség szerzett zavara a szóbeli és az írásbeli kommunikációt egyaránt érinti (Osmanné, 1997, Gósy, 2005). Míg a szóbeli nyelvhasználat vizsgálatára több jól használható, a beteg nyelvi képességének állapotáról átfogó, hiteles képet adó eljárás áll rendelkezésre (Osmanné, 1983, 2007), addig az olvasási készség vizsgálatához csak a WAB olvasásvizsgálat néven ismert teszt érhető el magyar nyelven (Net 1). Mivel ez az eljárás tapasztalatunk szerint nehézkes, értékelése nem egyértelmű, a kapott eredmény pedig nem tükrözi a beteg foglalkozások alatt nyújtott olvasási teljesítményét, célul tűztük ki egy új diagnosztikai eljárás kidolgozását.

   Vizsgálóeljárásunk elméleti alapját Ellis és Young egyesített szófelismerési modellje adja (Ellis, 2004). Célunk az egyes olvasási utakon nyújtott teljesítmény feltárása volt annak érdekében, hogy a megtartottnak bizonyult útból kiindulva célzott terápiás módszer alkalmazását tegyük lehetővé a sérült utak helyreállításához. 

   Motoros túlsúlyú szenzomotoros afáziás betegek körében végzett első vizsgálataink tapasztalata, hogy anyagunk egyszerűen, gördülékenyen használható. Az eredmények azt igazolják, hogy a teszt alkalmas a különböző olvasási utakon nyújtott teljesítmények mérésére, ebből következően megfelelően támpontot ad a terápiás folyamathoz.
