Irland und Europa 2002 - 2009
Authors: Alioth Martin
Published: June 2021

Diese Publikation beginnt mit einem historischen Blick auf das Verhältnis zwischen Irland und der EU und versucht, die historischen Grundlagen für Irlands Blick auf Europa aufzuzeigen. Der zweite Teil dieser Publikation betrifft die Gegenwart. Die dramatische Wirtschaftskrise, die Irland in den letzten zwölf Monaten erfasst hat, führte nämlich zu einer deutlichen Verschiebung der irischen Wahrnehmung der EU. Namentlich die Zugehörigkeit zum Euro-Raum hat Irland bisher vor dem Schlimmsten bewahrt. So werden wir versuchen, die Umstände zu rekapitulieren, die letztes Jahr zur Verwerfung der Vorlage führten. Anschliessend kommen die Bemühungen der irischen Regierung zur Sprache, die zugkräftigsten Argumente der Gegner zu entschärfen, und schliesslich skizzieren wir die Ausgangslage vor dem eigentlichen Abstimmungskampf, der nach der Sommerpause beginnen wird.
Die Wirtschaftskrise - eine Chance für die Umwelt?
Authors: Conradt Sarah
Published: June 2021

Was bedeutet die Wirtschaftskrise für die Umwelt? Eine „Atempause“, also ein kurzfristige Erholung, oder zusätzlichen Stress? Stimmt das Kredo „jede Krise eine Chance“?In dieser Arbeit wird diese Fragestellung diskutiert, wobei nur auf den Klimawandel als Umweltproblem eingegangen wird. Zunächst wird der öffentliche Diskurs über das Verhältnis von Wirtschaft und Umwelt dargestellt. Hierfür werden die unterschiedlichen Meinungen analysiert, die in Zeitungen von beispielsweise Wissenschaftlern und Ökonomen vertreten werden. Im dritten Kapitel wird ein knapper Theorieteil über den Zusammenhang von Umweltbelastung und Wirtschaftswachstum bis hin zur Thematik der Entkoppelung dargelegt. Anschliessend wird Kohlenstoffdioxid (CO2) als Umweltindikator vorgestellt und das Europäische Zertifikatshandelssystem EU ETS erläutert. Dieses Emissionshandelssystem wird als Modell verwendet, um den Einfluss der Wirtschaftskrise auf die Umwelt oder genauer, den Einfluss auf den Umweltindikator, zu erörtern. Schliesslich werden zwei Thesen entwickelt, die im vierten Teil anhand empirischer Daten analysiert und diskutiert werden. Im letzten Teil werden die wichtigsten Punkte zusammengefasst und die persönliche Meinung dargelegt.

Authors: Ibrahim Rasha H. , Saleh Abdul-Rahman H.
Published: June 2021

An evaluation was achieved by designing a matlab program to solve Keplerâ€™s equation of an elliptical orbit for methods (Newton-Raphson, Danby, Halley and Mikkola). This involves calculating the Eccentric anomaly (E) from mean anomaly (M=0Â°-360Â°) for each step and for different values of eccentricities (e=0.1, 0.3, 0.5, 0.7 and 0.9). The results of E were demonstrated that Newtonâ€™s- Raphson Danbyâ€™s, Halleyâ€™s can be used for e between (0-1). Mikkolaâ€™s method can be used for e between (0-0.6).The term  that added to Danbyâ€™s method to obtain the solution of Keplerâ€™s equation is not influence too much on the value of E. The most appropriate initial Gauss value was also determined to be (En=M), this initial value gave a good result for (E) for these methods regardless the value of e to increasing the accuracy of E. After that the orbital elements converting into state vectors within one orbital period within time 50 second, the results demonstrated that all these four methods can be used in semi-circular orbit, but in case of elliptical orbit Danbyâ€™s and Halleyâ€™s method use only for e â‰¤ 0.7, Mikkolaâ€™s method for e â‰¤ 0.01 while Newton-Raphson uses for e < 1, which considers more applicable than others to use in semi-circular and elliptical orbit. The results gave a good agreement as compared with the state vectors of Cartosat-2B satellite that available on Two Line Element (TLE).

Published: June 2021

The aim of the study is the measuring of changes in the spectral reflectivity water quality, analyzing the seasonal difference of Tigris River within Mosul City in the north of Iraq using Geographic Information Systems (GIS) and remote sensing techniques during the period (2014-2018). For this paper, Satellite images of the 8 Landsat in 2018 for four seasons have been selected in order to study the seasonal changes on the river they took place during 2018.  A total of ten sample datasets were taken at the upstream, midstream and downstream along the Tigris River. This research focuses on analyzing the locational variance of reflectance, analyzing seasonal difference, and finding modeling algal amount change. There are distinctive reflectance differences among the downstream, mid-stream and upstream areas. Red, green, blue and near-infrared reflectance values decreased significantly toward the upstream. Results also showed that reflectance values are significantly associated with the seasonal factor. In the case of long-term trends, reflectance values have slightly increased in the downstream, while decreased slightly in the mid-stream and upstream. The modeling of chlorophyll-a and Secchi disk depth implies that water clarity has decreased over time while chlorophyll-a amounts have decreased. The decreasing water clarity seems to be attributed to other reasons than chlorophyll-a.

Published: June 2021

People who undertaken different X-ray examinations are already exposed to ionizing radiation which causes biological effects. Therefore assessing the patient radiation dose is a prerequisite element in optimizing the X-ray practice and to avoid the unnecessary radiation dose. The aim of this research is to assess the skin radiation dose for those patients who undertaking routine X-ray examinations in selected three hospitals in Al Najaf city.

     Three X-ray units were involved in this experimental study; these were belonging to three hospitals in Al Najaf city-Iraq, namely Al-Sadder teaching hospital, Al-Hakeem general hospital and Al-Zahraa hospital. Data of exposure parameters (tube potential (kVp), tube current (mAs) and source to detector distance (d cm)). The data were collected from 160 patients exposed to radiation during different X-ray examinations. Patients were chosen to be within adult range (>18 years) and the selection was random (male and female). Patient skin dose was calculated mathematically using an established formula depending on the recorded exposure factor (kVp, mAs and d). Different X-ray examinations were considered, namely skull Posterior â€“anterior (PA), skull Lateral (LAT), chest PA, chest LAT, abdomen Anterior-posterior (AP), pelvis AP, lumbar spine  AP and lumbar LAT. The average skin dose for all X-ray examinations considered in this research were as follow: 0.9, 0.76, 0.23, 0.41, 1.85, 1.82, 2.03 and 3.44 mGy, for skull PA, skull LAT, chest PA, chest LAT, abdomen AP, pelvis AP, lumbar spine(LS) AP and Lumbar spine (LS)LAT respectively. The results demonstrate that the dose values were comparable to those that were previously reported in published reference.

Published: June 2021

In this research, we obtained nanoparticles (NPs) using a type of microwave (cold plasma) and water extract from Origanum vulgare with the addition of silver nitrate (AgNO3) solution. Silver nanoparticles are characterized by high production techniques. Experimental factors such as morphology, structure, optical properties and active compounds of the nanoparticle extract were studied through specific tests such as morphology, UV spectroscopy, FE-SEM, FT-IR, and Atomic Force Microscopy (AFM). Plants were used in manufacturing the nanoparticles, as plants are well known for their accessibility and applicability in different pathological areas. The current research provides information on the Green Union System of Nanoparticles. It is concluded that, under the influence of cold plasma, the nanoparticles increased the nanoscale size of the molecules and thus increased the aggregation and the transformation of the pink color of the nanocrystal line to brown due to increased absorption.

Authors: Al Siaede Riaed S.
Published: June 2021

Geotechnical soil problems underneath foundation of hydraulic structures occurs due to engineering soil properties, geological setting and hydraulic properties of the projects. Two finite element programs of Geoslope 2012 software, SIGMA/W and SEEP/W, were used for analysis of in situ stresses, load deformation behavior, seepage quantity and vertical gradient below Teeb weir foundation, to compute factors of safety against seepage uplift. The site soil is a granular (gravel, sand and silt), weakly cemented soil cohered by gypsum and clay materials. The area has low lying topography, with slightly tectonic activities. The model results show that the upstream side stresses are reduced while the pore pressure are increased, indicating decreased stability. Soil displacement and settlement were measured and the effects of these displacements on the low cemented soil particles were discussed. The pressure distribution and vertical hydraulic gradient  measured and used for analyze the weir stability. Finally, the soil potential failure zones were drawn to fix the main risks in each sides of the weir.

Published: June 2021

The present study aims to assess inter-specific competition between Hydrilla verticillata and Ceratophyllum demersum. A competition experiment design has five treatment combinations to terminal shoots of C. demersum only, terminal shoots of H. verticillata only and three different treatment combinations of C. demersum and H. verticillata together. Our results showed parameters growth of C. demersum were decreased of which, total chlorophyll, protein, and biomass while Superoxide dismutase (SOD), and Catalase (CAT) enzymes increase were significantly (p<0.05) compare with control treatment. While H. verticillata were increased total chlorophyll, biomass, CAT and little increase in protein and SOD were significantly (p<0.05) compare with control treatment. Therefore, due to the competition, with the introduction of C. demersum, the performances growth of H. verticillata were increased. Based on our result, showed H. verticillata and C. demersum species were coexist, C. demersum will have a competitive advantage over H. verticillata. Therefore, this study suggests, H. verticillata could out-compete for C. demersum in many situations, that despite the similar ecology.

Published: June 2021

Purpose: The aim of the study was to describe the use of masks among health care personnel (HCP) exposed to index cases of coronavirus disease 2019 (COVID-19), and to evaluate any association with infection rate.

Methods: We did a retrospective, observational study of HCP at Zhongnan Hospital of Wuhan University for the management of COVID-19 (before person-to-person transmission was official confirmed, no additional protection was provided). A questionnaire was given to all staff listed on the roster in the clinical regions providing care for index patients with COVID-19. All participants were surveyed regarding hand-washing and use of surgical masks and gloves and were tested for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Data were analysed (Student’s t test and Pearson χ2 test) for an association between infection and use of personal protective equipment.

Results: Exposure of a total of 299 non-infected and 30 infected staff was confirmed. None of the 149 staff who reported use of all three preventative measures (hand-washing and use of gloves and masks) became infect-ed. In contrast, all 30 of the staff who became infected had omitted at least one of the measures. Fewer staff who wore surgical masks (P=0.000003) became infected compared with those who did not. Infections rates were significantly lower in HCP from the internal medicine departments, as these personnel generally wore masks.

Conclusion: An association was found between SARS-CoV-2 infection of HCP and the non-use of masks when working with index cases in clinical settings. We recommend that all HCP follow the strict instructions for prevention and treatment of nosocomial infection during intimate contact with COVID-19, especially staff from surgical departments.
The Role of Type III Interferons in Human Disease
Authors: Malik Aniko E. , Issekutz Thomas B. , Derfalvi Beata
Published: June 2021

Purpose: This literature review summarizes the main immunological characteristics of type III interferons (IFN) and highlights the clinically relevant aspects and future therapeutic perspectives for these inflammatory molecules.

Source: Relevant articles in PubMed MEDLINE from the first publication (2003) until 2020. N=101 articles were included in this review.

Principal findings: Type III IFNs represent a relatively newly described inflammatory cytokine family. Although they induce substantially similar signalling to the well-known type I IFNs, significant functional differences make these molecules remarkable. Type III IFNs have extensive biological effects, contributing to the pathogenesis of several diseases and also offering new diagnostic and therapeutic approaches: 1) their potent anti-viral properties make them promising therapeutics against viral hepatitis and even against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is causing the current coronavirus disease 2019 (COVID-19) pandemic; 2) imbalances in the IFN-λs contribute to several forms of chronic inflammation (e.g., systemic and organ-specific autoimmune diseases) and potentially predict disease progression and therapeutic response to biologic therapies; and 3) the antitumor properties of the type III IFNs open up new therapeutic perspectives against malignant diseases.

Conclusion: Over the last 18 years, researchers have gathered extensive information about the presence and role of these versatile inflammatory cytokines in human diseases, but further research is needed to clarify the mechanistic background of those observations. Better understanding of their biological activities will permit us to use type III IFNs more efficiently in new diagnostic approaches and individualized therapies, consequently improving patient care.

Published: June 2021

This case study aims to analyze how preschool educators can play the role of language educators (Spanish and English) and how their pedagogical and teaching practice is being transformed. This study considers the theoretical framework behind the constructivist paradigm, which states that the context, participants' actions and views, and historical elements all play a part in constructing a theory. That truth is relative depending on one's perspective, while also focusing on establishing a rigorous and thorough process throughout this study, focusing on qualitative research principles (Creswell, 2014). The findings show that preschool educators can significantly improve their communicative competence, particularly in discourse, strategic and socio-cultural competencies. Furthermore, through reflection and self-assessment, preschool educators refine their classroom practices and enhance their conception about teaching English to preschool learners.

Political power and fear: dialectics of interpenetration
Authors: Barinov Dmitrii Nikolaevich
Published: June 2021

This article is dedicated to the problem of fear as a phenomenon of political power and dominance-subordination relations. The theoretical-methodological framework for the analysis of correlation between fear and political power is comprised of the works of Russian and foreign philosophers and sociologists (O. Comte, H. Spencer, T. Parsons, N. Luhmann, E. Shils, A. S. Panarin, and other.). The author examines such phenomenon as the fear of punishment, the peculiarities of occurrence of fear in the conditions of total control over citizens under despotic and democratic political regime, in the situation of destruction of the government. Characteristic is given to the fears of politicians (personal fears, fear of losing power, fear of democracy). Based on the theoretical models along with attracted historical and statistical material, it is demonstrated that fear is an inevitable side effect of any power that tends to conservation of the existing model of relations between the government and society. The article provides a new interpretation of the idea of the supporters of psychoanalysis on channeling the fears of politicians onto the population. It is underlined that in the current conditions, it is not so much the fears of the political elite, as on converting them into a governing technique. The latter conceals the true concerns of the political elite, as well as displaces the moods of discontent and social tension, turning them into fear towards the objects developed in the information field.
Males que vêm dos deuses: esboço de uma antropologia da doença na Grécia Antiga
Authors: Bacelar Agatha Pitombo
Published: June 2021

Ancorada na materialidade do corpo, a elaboração sociocultural da doença é reveladora das antropologias nativas, da produção de modelos do humano no seio das culturas. Por mais que a irrupção de problemas biológicos tenha alcance universal, afetando humanos no mundo inteiro ao longo de todas as épocas, as maneiras de experimentá-los e de concebê-los, as práticas segundo as quais são enfrentados e as relações intersubjetivas em torno deles tecidas são construídas no interior de uma situação cultural e histórica bem específica. Dialogando com estudos de antropologia da doença, o presente artigo investiga as dinâmicas de sentido subjacentes às representações de doenças como forma de punição divina na Grécia antiga, sobretudo em Hesíodo e Homero. Constata-se que a atribuição da origem de doenças às divindades pode tanto se inscrever em uma vindicta específica quanto remeter ao caráter fortuito das doenças a que toda gente está suscetível. Contudo, ambos os sentidos não deixam de articular a ordem do corpo e a ordem social. Na medida em que o antropomorfismo divino grego faz coincidir em um único vocábulo, timé, a estima social humana e a divina, que se expressa em atos de culto, a doença pode remeter à justiça divina quer em uma dinâmica retributiva como punição, quer em uma dinâmica distributiva que garante a distinção ontológica entre mortais e imortais.

Purpose. To compare and evaluate long-term results of two-stage surgical treatment of patients with advanced proliferative diabetic retinopathy and complicated incipient cataract. Material and methods. 73 patients with advanced proliferative diabetic retinopathy and complicated incipient cataract performed by vitrectomy from 2016 to 2020 were analyzed. In the 1st group patients were subjected to a two-step surgical procedure: vitreoretinal surgery with silicone oil tamponade performed as the 1st step in their treatment; followed by the 2d step, phacoemulsification surgery and silicone oil removal, and the IOL implantation, respectively. In the 2d group phacoemulsification performed simultaneously with vitreoretinal surgery: phacoemulsification, IOL implantation, vitreoretinal surgery with silicone oil tamponade. The second step differed in the removal of silicone oil from the vitreous cavity. Results. Visual functions improved in 88.8% of cases in group 1, and in 51.3% in group 2. Conclusion. Outcomes of the studies suggest that it is more viable to perform phacoemulsification surgery sometime later along with silicone oil removal on PDR patients with complicated primary cataract. This sequence of treatment procedure ensures a more gentle approach to the anatomic structures of the eye during the first stage (vitreoretinal surgery) and contributes to the reduction in the number of intraoperative and postoperative complications. Key words: diabetic retinopathy, cataract, vitreoretinal surgery.

Currently, vitreoretinal surgery is one of the most effective methods of treating macular holes that can improve the quality of vision, and the most common method of such treatment is vitrectomy with the removal of the internal border membrane around the rupture and the use of autoplasty of the internal border membrane. Microperimetric retinal testing measures the sensitivity of the retina at certain points on a larger surface and detects relative or absolute microscotomas, which allows you to objectively assess the state of the central part of the retina. At the same time, the search for ways to reduce the risk of macular surgery complications and improve functional results continues. Purpose. To propose a new technique for macular tear surgery, which is based on autoplasty of the VPM and reduction of microtraumatization of the retinal layers. Material and methods. The results of surgical treatment of 240 patients (240 eyes) with a diagnosis of macular holes were analyzed. All patients underwent surgical treatment for MH. Depending on the method of closing the macular hole, the patients were divided into two groups: group 1 – patients who underwent surgical treatment using the standard introverted flap technique. Group 2 – patients who were operated on according to the original method with partial peeling of ILM in the macular area. All parameters in the preoperative period were statistically comparable. Results. The most significant are the results obtained on the 30th day after surgical treatment. According to the results of surgical treatment, there was a significant excess of light sensitivity parameters in the nasal part of the pattern used: the upper-nasal and lower-nasal quadrants, where peeling was not performed. Conclusion. During this technique, there is a preservation ILM, which reduces the risk of intraoperative damage to the retinal layers. A higher functional result was obtained.

Purpose. To assess the clinical effectiveness of the developed surgical method for treating paralytic strabismus. Material and methods. The operation was performed on 32 patients with paralytic strabismus (32 eyes) aged 3 to 12 years. All patients had diplopia in the primary gaze position or in a small abduction. Convergent strabismus was diagnosed in 26 children (81%), divergent strabismus – in 6 patients (19%), in 34% of cases (11 people) strabismus was with a vertical component. Strabismus angle according to Hirshberg before surgery: horizontal deviation from 10 to 30°, vertical – from 5 to 15°. Results. On the 7–10th day after the operation, orthotropy and the appearance of mobility of the eyeball towards the affected muscle were achieved in all operated patients. In the long term (6–12 months) after surgery, 23 children (72%) fully recovered the mobility of the eyeball in 8 directions and formed stable binocular vision, and orthotropy remained. In 9 patients (28%), there was a limitation of the mobility of the eyeball to 5–7°. Conclusion. The proposed method for the surgical treatment of paralytic strabismus makes it possible to achieve in one stage the correction of the deviation angle and the improvement of mobility with the elimination of diplopia, avoids the appearance of postoperative vertical deviation and eliminates large deviation angles. Using the proposed method, it is possible to simultaneously correct both horizontal and vertical deviations. Key words: paralytic strabismus, deviation angle, horizontal deviation, vertical deviation.

Purpose. To study effectiveness combination of topical corticosteroid therapy and sulodexide in complex treatment of patients with isolated optic disk vasculitis (IODV). Material and methods. The study included 17 patients with IODV (middle age was 26.7±6.2 years on average). Depending on different of additions to topical corticosteroid therapy, the patients were divided into two groups: the main group (8 people), treatment regimen of which additionally included sulodexide during and after the end of inpatient treatment, and the control group (9 people), which at inpatient treatment sulodexide was not prescribed, and then picamilon was prescribed. The results of treatment were assessed according to the measured of best corrected visual acuity (BCVA), static perimetry with determination total number of scotomas (TNS) in the central visual field, and the central retinal thickness (CRT) was examined. Morphometric indicators of intact eyes were taken as variant of the norm. Based on the data of ophthalmoscopy and biomicroscopy, the total clinical index of inflammation (TCII) was calculated. All studies were performed upon admission of patients to inpatient treatment and after its completion, and then after 1, 3 and 6 months. Results. As result of study, an increased efficacy of pharmacotherapy in patients with IODV was established when sulodexide is included in the complex treatment. We noted: reduction times of disappearance of TCII by 1.6 times; increase of BCVA by 3 times after 6 months; disappearance of TNS in the central visual field is 2 times faster; restoration of CRT to normal values by 3 times faster. Conclusion. Comparative analysis of clinical efficacy of complex treatment of IODV, including topical corticosteroid therapy and sulodexide, allows us to recommend it for use in clinical practice.

Purpose. To study the frequency, structure and outcomes of keratitis caused by wearing contact lenses. Material and methods. A continuous sample of all cases of the incidence of keratitis provoked by an error in wearing contact lenses in adult patients from 2017 to 2019 was carried out. All of them underwent inpatient treatment for this matter in the ophthalmological department of the City Clinical Hospital No. 10 of the Ministry of Health of the Khabarovsk Territory. The provoking factors, etiological structure, the frequency of restoration of visual functions and the outcomes of these keratitis were determined. Results. The total number of cases studied was 51 (52 eyes). Keratitis was provoked by wearing soft contact lenses (SCL) mainly in females (76.5%) aged 20– 30 years. Lenses were selected mainly for moderate myopia (44%). Bacterial etiology of keratitis was detected in 61% of cases, mixed – in 31% of cases, viral – in 8%. The main reason for the development of keratitis is violations in the mode of using SCL (sleep in lenses, prolonged use of SCL with an expired wearing period, violation of the rules for caring for lenses). Conclusion. In the structure of keratitis, provoked by wearing SCL, there were mainly bacterial keratitis (61%). The predominant factors contributing to the formation of keratitis were: sleeping in lenses (51%) and prolonged wearing of lenses exceeding their useful life (24%). The treatment made it possible to completely restore visual functions in 38% of patients. Key words: keratitis, soft contact lenses, myopic refraction.

Clinical case of successful treatment ocular hypertension caused by organic closure of anterior chamber angle after penetrating keratoplasty is presented. The patient underwent keratoplasty in the right eye and on the first day after the operation the clinic of acute glaucoma attack in the operated eye was revealed. In view lack of effect from medication and laser treatment carried out, the synechiae surgical removal was done. Carbachol Intraocular Solution (0.1 ml MIO-CHOL Sterile Solution, APPASAMY OCULAR DEVICES (P) LTD. (PHARMA DIVISION), India) was injected into anterior chamber to narrow the pupil. But its action turned out to be paradoxical – instead of constriction there was sharp pupil dilation. In addition to standard treatment, the patient received keratoprotection and reparative therapy. To restore neurotrophic processes in the iris, intravenous infusions of 1000 mg of gliatilin were first performed, followed by a switch to the tablet form of this drug. After 4 months, the patient experienced increase in uncorrected visual acuity to 0.1; best corrected visual acuity – up to 0.2 with diaphragm against the background of complete absence of signs of inflammation. The graft was completely transparent, the intraocular pressure – 19 mm Hg, mydriasis persisted 5–6 mm, the reaction of the pupil to light appeared, but was weakened. Key words: ocular hypertension after penetrating keratoplasty, acute glaucoma attack, synechiae surgical removal.

Progress in the treatment of Chronic Myeloid Leukaemia (CML) has significantly improved the survival rates and prognosis of these patients. As a result, there is a growing awareness of the adverse effects that the treatments used can have on the Cardiovascular (CV) system. A high percentage of patients develop sequential resistance to CML treatments and, in these cases, ponatinib represents a good therapeutic option that has been associated with cardiovascular events. This required the development of recommendations for its management. A Delphi analysis conducted by a multidisciplinary panel of experts developed and agreed on clinical practice recommendations to optimize cardiovascular risk control in CML patients requiring ponatinib treatment.

Background: Children with Autism Spectrum Disorders (ASD) are at particular risk of impairment in social interaction, repetitive and stereotyped behaviors, and a poor quality of life. We tested whether applied behavior analysis intervention could, compared to a control condition, reduce repetitive and stereotyped behaviors, and increase social skills and thus enhance the quality of life among children with ASD. Methods: Thirty children with ASD (mean age: 6.5 years) were randomly assigned either to applied behavior analysis intervention or to a control condition. All participants completed Gareth test on stereotypical behaviors, social communication, and interaction skills at the following time points: baseline, and six months later at completion of the intervention. Findings: Stereotypical behaviors, social communication, and interaction skills improved over time from baseline to intervention completion, but more so in the applied behavior analysis intervention than in the control group. Compared to the control group, the applied behavior analysis intervention group reported had more positive scores. Conclusion: The findings suggest that among children with ASD and compared to a control condition, applied behavior analysis intervention has the potential to improve symptoms of autism, thus contributing to their quality of life.
