An early echocardiographic prediction for functional myocardial recovery after ST elevation myocardial infarction
Authors: Karakus Alper , Uğuz Berat
Published: March 2021

Goals Discrimination of the time course of functional recovery in early period following ST elevation myocardial infarction (STEMI) has prognostic importance. This study aims to establish the ability of the combined systolic-diastolic index (E / (Ea x Sa), for differentiating recoverable myocardium or persistent non-viability in subjects with STEMI.Material and methods 77 patients with first acute STEMI were enrolled to the study. Serial transthoracic echocardiography (TTE) examinations were performed at the time of the admission (immediately after reperfusion), hospital discharge (5±1 days) and control examination (30±2 days). To assess the association between E / (Ea×Sa) index and myocardial recovery, two categories (Transient stunning and persistent non-viability) were defined on basis of improvement of left ventricle ejection fraction (LV EF) (Improvement was defined as an increase more than 10 % in LV EF at day 30 compared to baseline).Results 55 patients (71.4 %) had improvement of LV EF and 24 patients (28.6 %) had no recovery of systolic function (30 days LV EF 48.78±6.1 vs. 39.31±8.1 %, p=0.01). The E / (Ea×Sa) index were significantly higher in the “non-viability” than in stunning group on predischarge and 1 month (1.61±0.64 vs 1.25±0.43, p=0.01 and 1.33±0.25 vs 1.14±0.21, p=0.01, respectively). The change in the E / (Ea×Sa) index in early period (within 5±1 days) was higher in the stunning group (26 %) compared to non-viability group (15 %) (p=0.033). E / (Ea×Sa) index was found to be a significant predictor of myocardial recovery in multivariable logistic regression (OR 0.91, 95 % CI 0.83–0.98, p=0.001). Roc curve showed that the cutoff value of E / (Ea×Sa) index is 1.29 with 73 % of sensitivity and 61 % of specificity (AUC: 0.71, p=0.01, CI: 0.54–0.89).Conclusions Our findings suggest that E / (Ea×Sa) index is a strong predictor of functional recovery; the odds of recovery decreases as E / (Ea×Sa) index value increases.

AIM: To evaluate the safety, refractive outcomes and vision after phakic posterior chamber implantable collamer lens (ICL) after keratoplasty (KP).
METHODS: This retrospective single center study evaluated 32 (35 eyes) patients who received an ICL for myopia and/or astigmatism after keratoplasty. Patients underwent ICL surgery if they were unable to wear glasses or contact lenses and excimer laser surgery was contraindicated. Data were collected on uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), refraction and complications. Data were analyzed for the preoperative and last postoperative visits (16.7±13mo) (P<0.05).
RESULTS: Preoperatively, spherical equivalent (SE) ranged from -4.00 to -20.00 D and cylinder from -2.00 to -9.00 D. The mean SE decreased statistically significantly from -11.41±3.62 D preoperatively to -1.95±1.78 D postoperatively (P<0.0001). Mean UDVA increased statistically significantly from 20/400 preoperatively to 20/25 postoperatively (P<0.0001). There was a mean improvement in postoperative CDVA of 1.5 lines compared to preoperatively, 37% of eyes had an increase of 2 or more lines. One eye (2.8%) lost ≥1 line of CDVA. There were no intraoperative or postoperative complications.
CONCLUSION: Posterior chamber phakic intraocular lens implantation is a safe and effective treatment for post-keratoplasty myopia and astigmatism in patients unable to wear spectacles or contact lenses and where corneal refractive surgery is contraindicated.

AIM: To develop a feasible method to correct congenital ptosis in children.
METHODS: Sixty-four patients (102 eyelids) were divided into three groups based on the degree of ptosis: mild (<2 mm); moderate (3-4 mm); and severe (>4 mm). All patients underwent the same levator resection surgery in which the suspensory system of the LPS is retained. After capturing a standard photograph of primary position, the height of the superior palpebral margin was measured preoperatively by using Image J software to calculate its ideal height required during surgery. Postoperative outcome measures included upper eyelid margin height, degree of scleral exposure and exposure keratitis. The patients were followed-up at 1wk, 1mo and 6mo postoperatively.
RESULTS: In the early postoperative period, except two cases with overcorrection, the positions of the eyelid upper margins were normal in all cases in the mild and moderate groups. Six months postoperatively, the eye with overcorrection in the moderate group showed improvement, while the eye in the mild group did not. Seven eyes in the severe group exhibited residual ptosis to varying degrees. The eyelids exhibited appropriate closing functionality; exposure keratitis was absent.
CONCLUSION: Using this preoperative quantification technique to guide surgery not only provide a gauge for LPS shortening under general anesthesia, but also increase the success rate of surgery.

AIM: To assess the efficacy, safety, stability and predictability of an implantable Phakic contact lens in patients with stable keratoconus.
METHODS: The uncorrected and the best corrected visual acuity, defocus curve, contrast sensitivity, refraction and possible side effects were measured in 14 patients after utilizing implantable phakic contact lens (IPCL) to correct refractive errors. The result was assessed for more than 6mo.
RESULTS: The mean preoperative spherical equivalent (SE) and astigmatism got changed from -6.94±2.79 DS and -4.24±1.42 DC to -0.23±0.43 DS and -1.05±0.49 DC, respectively at the last examination after 6mo. Before the preoperative the mean Snellen visual acuity was 0.18±0.10 logMAR. The mean uncorrected and the best corrected visual acuity got changed to 0.13±0.10 logMAR and 0.05±0.15 logMAR, respectively in 6mo. The mean safety indices were 1.11. There was no loss of visual acuity in any of the eyes and 22 eyes (78.5%) gained one or more lines. Twenty eyes (71.4%) were within 0.50 ?D and 27 (96.42%) were within ±1.00?D of the desired SE refraction. There was a change in manifest refraction of -0.23±0.43 (range from -1.00 to +0.75) from the first week of surgery to 6mo. Contrast sensitivity got improvement value at 3 per degree (P<0.005) after Toric IPCL implantation. The total 6mo corneal endothelial cell loss (ECL) was <5%. Intraocular pressure (IOP) was 11.32±2.28 mm Hg after 6mo.
CONCLUSION: The clinical consequences of the present study exhibit the efficacy, safety, and predictability of Toric implantable Phakic contact lens in the correction of myopia and myopic astigmatism related with stable keratoconus.
Investigating the Influence of Dam-Breach Parameters on Dam-Break Connected Flood Hydrograph
Authors: NAJAR Mohamed , GÜL Ali
Published: March 2021

The dam-break connected flood hydrograph properties primarily depend on the breach geometry and the time for the breach to fully develop. Therefore, the prediction of dam’s breach geometry is essential in dam-break studies. To understand the impact of breach parameters on flood peak hydrograph, five of the most common breach prediction methods are implemented in the presented study to estimate the flood hydrographs using 2-dimensional HEC-RAS model. The Ürkmez Dam is chosen as the case study due to the presence of a residential settlement located right at the dam downstream where undesirably any breach of the dam body can have inevitable and dramatical risks on downstream populations and properties. Various levels for reservoir storage are investigated in each method. In order to assess the impact of each breach parameter on the resulting flood hydrographs, sensitivity analysis is carried out. The peak discharge rates and the times to peak for each analyzed scenario are investigated and discussed. Results reveal that Froehlich approach is the most reasonable method for estimating dam-breach parameters as far as exemplified in the Ürkmez Dam case. Furthermore, sensitivity analysis points out that the parameter of the breach side slope has no major influence on the time to peak while having an insignificant impact on the peak discharge. Besides, the study exhibits that both the peak discharge and the time to peak characteristics are highly sensitive to breach time formation parameter. In the light of these targeted findings, the study is aimed to contribute to other relevant research in designating the set of key parameters in experimental or modeling efforts in a way to limit the uncertainty that substantially originates from personal judgment.

Published: March 2021

The results of the study of the ecological condition of small watercourse in the areas of influence of various mainly organic, agricultural sources of pollution are presented. In terms of contamination with organic matter and compounds of biogenic elements, the watercourse belongs to the category "very dirty" and hypertrophied. Ammonium ions are shown to be a priority pollutant of the watercourse. Biotesting and laboratory modeling methods have studied their effect onDaphnia magna Sr.hydrobiont filters on the mortality of the daily young with 96 hours of cultivation. It has been established that nitrifying bacteria have a wide range of tolerance to ammonium nitrogen. The optimal concentration for their life is the concentration of NNH4+and 3.2 mg/dm3. Ammonium nitrogen is toxic toDaphnia magna Sr.freshwater rhacies at a concentration of more than 4 MPC (1.6 mg/dm3). It is noted that the system of environmental control of small rivers should be revised towards tightening, since it is the small watercourses that serve as the numerous primary contaminants of large river basins.

Published: March 2021

El artículo explora los proyectos de reforma política en el caso brasileño desde un aspecto inexplorado: las estrategias para maximizar las ganancias electorales inherentes a las propuestas de reforma electoral. Para ello, analizamos las Propuestas de Reforma Constitucional (PEC) presentadas en el Congreso Nacional sobre el tema de los 29 años de democracia brasileña y creamos una base de datos con 493 observaciones con 52 variables que agrupamos en 5 categorías de análisis. De la literatura (Benoit, 2007; Boix, 1999; Colomer, 2004, 2005, 2018) pretendemos inferir sobre los diseños propuestos en los PEC, evaluando las posibles ganancias y pérdidas estratégicas para las partes. Los resultados muestran que los PEC no parecen estar guiados por intereses estratégicos de las partes, como se predice en la literatura. Por el contrario, la investigación sugiere una racionalidad normativa (sin maximizar las ganancias).

Providing of Reasonableness in Decisions of the Constitutional Court in the Scope of Recognition of the Echr’s Decisions
Authors:   Chernivtsi National University, Ukraine, BZOVA Laura
Published: March 2021

The relevance of the study of judicial reasoning in public law is related to the challenges of modern litigation, which require new approaches to the construction of a court decision. This is also due to the constitutional reform in Ukraine, in particular the latest amendments to the Constitution of Ukraine in the field of justice. The emergence of the priority issue of constitutionality led to the rupture of the system, where the protection of fundamental rights in a particular issue was essentially ensured in accordance with the case law of the European Court of Human Rights. The Constitutional Court of Ukraine always uses the decisions of the European Court of Human Rights to form its own legal positions, after which they actually become a substantive element of the motivating part of the decision of the Constitutional Court of Ukraine. It is concluded that regardless of whether the decision of the European Court of Human Rights has been ruled on Ukraine or not, it is a source of constitutional law of Ukraine.

Human rights are an inalienable right of everyone from birth. Respect for human rights and freedoms is seen as an indicator of the development of society. The Convention on the Rights of the Child, adopted in 1989 by the UN General Assembly and entered into force a year later, profoundly changed the world treatment of children. Like the Universal Declaration of Human Rights, the Convention formulated something fundamental to human well-being and acted as a watershed and a guide for future generations. According to the provisions of the Convention, the child is an active member of the family, community and society. The announcement of the Global Movement for Children in 1999 marked the beginning of major changes. All over the world, the movement aims to unite all those who believe that children's rights should be a priority. One of the main goals of the movement is to provide a clear understanding that the world's citizens care for children and expect governments to keep their promises.

The article is devoted to the study of human rights in terms of data available to an indefinite number of persons in the electronic services of the site Judiciary of Ukraine. It is established that along with the availability of the Internet the protection of fundamental human rights should be developed in any information environment. It is proved that the possibility of litigation online is combined not only with the availability of the Internet of a person - a participant in the process but also the current technical inability of a significant number of courts to onduct high-quality court hearings. The main obstacle is the poor quality of communication infrastructure and the lack of knowledge and skills of using digital technologies of the majority of the population. These obstacles must be removed by the State which has a duty to provide the basis for the dignified treatment of every member of society. It has been found that the openness of court decisions affects access to justice and does not promote respect for the rights of individuals to the confidentiality of personal data private and family life. It is substantiated that the indefinite storage of electronic copies of court decisions violates the human right to be forgotten. In order to overcome the identified gaps in the regulation of the use of digital technologies in the judiciary it was concluded that a clear regulatory environment should be created to achieve a balance of interests of the state and society and protect fundamental human rights in the digital age because the essence of man and changes.

Methodology of overhead power transmission line pylons technical state assessment with typical exploitation faults accounted
Authors: Burnysheva T.V. , Kozhevnikov A.N.
Published: March 2021

Structure safety estimation via the results of modal testing is widely used in building field. However, overhead power line pylons are so specialised that it is not possible to expand existing standards so that those could be employed to assess pylon conditions. These standards do not contain any information about the pylon eigenvalues, methodology of full-scaled experiment execution or criteria to differentiate pylons with respect to the extent of the structure defects occurred. This means that it is necessary to develop a dedicated approach to estimating the safety of this type of structures. The method proposed boasts an additional advantage, that is, it takes into account the operating defects that are typical for the type of structures under consideration. The point of this method is comparing the computed and experimentally determined natural frequencies of overhead power line pylons. This comparison enables us not only to detect the defect type present in the structure, but also to find whether it is located closer to the base of the structure or in the latticework on one of the sides. The paper presents the results of using our method for estimating the safety of intermediate towers for a 110 kV overhead power line as represented by the SV-5 segment and states the advantages of using our method when planning real-time inspection of structures, as well as for monitoring select towers constantly.

Published: March 2021

Background: Several animal species may act as a possible reservoir for transmission of MRSA to human. The aim of this study was to determine the antibiotic resistance profiles of Staphylococci from animals. Methods: A total of 754 nasal and rectal swab samples collected from apparently healthy animals at Batna and Setif governorate, eastern Algeria. For this purpose, we studied the antimicrobial susceptibility of the isolates by conventional methods (Disk diffusion test and methicillin resistance by Cefoxitin disk diffusion test). Result: The overall prevalence of S. aureus isolates from 754 samples was 43.61%, with a high rate of S. aureus isolation in rabbits (92%). Goats, bovine, dogs, cats, horses, poultry presented a medium prevalence with 31.91%, 25%, 23.75% 21.25%,15% and 15% respectively, while the lowest rate was observed in sheep with 10%. MRSA were isolated in all animal species (29.46%). All detected isolates were multiple drug resistant (MDR). A complete resistance (100%) was noted for ciprofloxacin and gentamicin in sheep and horses and to penicillin in dogs. MRSA is a serious problem for human and animal health; therefore, several experiments must be carried out to demonstrate possible transmission of MRSA between companion or food-chain animals and humans, as well as some MRSA clones of human origin that have adapted to new animal hosts eventually by losing useless virulence factors or acquiring new mobile genetic elements.

Published: March 2021

Background: Brinjal is one of the most popular and important vegetable crops grown throughout the year in India and other parts of the world. Though a large number of brinjal genotypes are available in India, only a few have good quality and yield during kharif. Therefore, the current study was carried out to identify and/or superior varieties with high yield and better quality brinjal during kharif, 2017-2018 consisted of thirty brinjal genotypes obtained from different places of India. Methods: All the genotypes were evaluated for fifteen morphological and six biochemical characters viz., plant height (cm), plant spread (cm), number of primary branches per plant, leaf blade length (cm), leaf blade width (cm), number of leaf prickles, days to first flowering (days), days to 50% flowering (days), fruit pedicel length (cm), fruit length (cm), fruit circumference (cm), number of fruits per plant, fruit weight (g), fruit yield per plant (kg), fruit yield per hectare (t), moisture content (%, FW), crude fiber content (%, DW), crude protein content (%, DW), ascorbic acid (mg/100g FW), solasodine content (mg/100g DW) and total phenol content (mg GAE/g FW). Result: Mean performance of brinjal genotypes revealed significant variation for morpho-biochemical characters. This variation may be due to the effect of genotype, environment or their interaction. Morphological characters of brinjal genotypes revealed that among the thirty genotypes, eighteen genotypes viz., Kuchia, Brinjal-3, Khoruah-1, Brinjal-6, Brinjal-8, Brinjal-4, Seujia Bengena, Brinjal-1, Brinjal-9, Brinjal-2, Brinjal Long, Green Long, Boga Bengena, Kajala, Sagolishingia, Long Khoruah, Brinjal-7 and Koni Bengena were found to be the superior performers for fruits/plant, primary branches per plant, days to first flowering, days to 50% flowering and fruit yield during kharif. The mean performance for biochemical characters also revealed wide variability among the genotypes in respect to quality performance.

Published: March 2021

Background: This study was conducted to explore the contribution of poultry farms to the contamination of the environment with ESBL-producing Escherichiacoli and there with, potentially to the spread of these bacteria to humans and other animals. Hence, the present work is a poultry farm based study aimed to detect prevalence of ESBL producing E.coli among poultry of small scale farmers. Methods: ESBL-producing E. coli were detected at poultry farm (n=40). The E. coli was isolated from poultry droppings in irrespective of diseases. The required data were collected through well-structured interview schedule in farm premises. E.coli isolates were more susceptible to Gentamicin, Aztreonarm, Cefrtrazindime and Cefotoxime. Result: Detection of ESBL isolates was performed by Combined Disc Diffusion Methods. Out of 40 E.coli isolates 12 were phenotypically identified as ESBL producers. The prevalence of CTX-m gene is 50% and Bla (TEM) gene is 50%.

Background: Assessment of semen quality of bulls in frozen semen stations is of paramount importance as they are used for inseminating large number of cattle. The present study was conducted to assess the in vitro fertilisation capacity of crossbred bull semen cryopreserved during different seasons in Kerala as reports of such an evaluation are scarce. Methods: Semen samples from six crossbred bulls of same exotic inheritance, cryopreserved during rainy, post monsoon and summer seasons were procured from KLDB, Dhoni. The collected samples were evaluated for their in vitro fertilisation potential. Result: Hot dry summer season in Kerala adversely affects the fertilisation capacity of spermatozoa. Rainy season was observed to be the most favourable season for good quality semen production and post monsoon season was intermediate between summer and rainy season. It can be concluded from the present investigation that semen cryopreserved during summer season have lower fertilisation and cleavage rate than rainy and post monsoon season. This might be due to the harmful effect of significantly higher average maximum temperature and lower relative humidity occurred in the area during summer season on spermatogenesis.
Genetic Relationship and Assessment of Variability of Mungbean [Vigna radiata (L.) Wilzek] Genotypes Based on Morphological Traits
Authors: Kumar Vinod
Published: March 2021

Background: The present investigation was undertaken to examine the genetic variability and relationship between traits among the 73 germplasm lines of mungbean collection of diverse nature. Genetic variability and association studies play an important role in developing a new genotype. The mungbean productivity remains low in India because of low genetic base for yield improvement, absence of variability for yield traits, poor ideotype of mungbean plant, inadequate management of the crop, weed infestation and susceptibility to biotic and abiotic stresses. Genetic variability is most important factor of success of any crop improvement programme. Methods: An experiment was conducted in a completely randomized block design with two replication at Regional Agricultural Research Station, Sagar, Madhya Pradesh in high productive black cotton soils during kharif 2016 on 73 mungbean genotypes. Result: The study revealed that the mean sums of squares due to genotype were highly significant for all the morphological traits. High estimates of heritability and genetic advance were recorded for clusters per plant, no. of branches per plant, days to maturity, seed yield, days to 50% flowering; plant height and no. of pods per plant indicating the role of additive gene effects with low environmental influence for the determination of these traits and simple phenotypic selection may be effective. The results also indicated improvement through direct selection for these traits can increase directly the grain yield in mungbean. Genotype Pusa Baisakhi, HUM-16, IPM-02-03, IPM-02-19, PM-5, AKM-9904, COGG-912 and RMG-991 were found good donors for these traits in recombinant breeding programme for yield enhancement in mungbean.
Primary school-level responses to the COVID-19 pandemic in Ethiopia: Evidence from phone surveys of school principals and teachers

Published: March 2021

Located at the intersection of the education system, the school and community, school principals now have the responsibility for the effectiveness of school-level responses to the COVID-19 crisis. This includes translating directives into practice during school closures as well as supporting teachers to continue to provide learning and responding to local needs, including the specific needs of disadvantaged students. Subsequently, teachers have a direct responsibility for supporting students during school closures, especially those who are disadvantaged. This article aims to provide an understanding of the response of school principals and teachers during school closures using data collected in Ethiopia through phone surveys with 127 school principals and 316 teachers in August 2020. We explore the support school principals received from the government during school closures as well as contact by school principals and teachers with parents and caregivers. Our findings suggest an important role for the local government in supporting school-level responses to the COVID-19 pandemic while parents and caregivers are important in helping to cater for the needs of disadvantaged groups.

For a competitive organisation, it is important to invest in employee's education to keep their knowledge up to date and ensure continuous growth in terms of employees' competence and skills. Continuous learning is considered as one of the success factors for the organisation, since this ensures constant growth of employees' competence that results in productiveness and effectiveness in its product development. Nowadays, more and more organisations are investing in performance analytics, Big Data analytics, artificial intelligence and process automation that are strongly related. However, such initiatives and projects can fail due to the lack of skills and competence of employees, which is strongly related to certain learning barriers. Therefore, the objective of the article is to create a conceptual framework for the elimination of learning-related barriers. The methods employed in this research are scientific literature analysis, synthesis and logical analysis of information, comparison of information, systemisation and visualisation. The conceptual framework illustrates the learning process for learning-related barriers elimination and suggests learning solutions: e-learning, mentoring, in house sessions, generic courses and external training solutions such as conferences and seminars.

Internet gaming disorder: Remarks of psychiatrists
Authors: Yesilyurt Ferahim
Published: March 2021

Psychiatrists were interviewed to elicit their remarks on and clinical experiences with Internet Gaming Disorder (IGD). A case study design with four open-ended questions was chosen. Psychiatrists were asked to answer questions related to the clinical cases they encountered, what they have gone through and what they think about the diagnosis of IGD. Purposive sampling was employed and eight psychiatrists working in Ä°stanbul made up the study sample. There have been numerous studies focusing on its prevalence and treatment but, to the best of authorâ€™s knowledge, there are no studies on psychiatristsâ€™ experiences with and remarks on IGD. Therefore, the current study will contribute to the literature by shedding light on practical knowledge and experience, which is as much important as theory. The findings showed that psychiatrists diagnosed a few of the patients suspected of IGD with depression, anxiety disorder and attention-deficit/hyperactivity disorder as comorbidities. Medications were often used to treat comorbidities and cognitive behavioural therapy in some cases. They also stated that they had difficulties while applying the criteria for diagnosis and paid attention to various symptoms. Functionality was reported as the most important criterion and it was suggested to be coded separately in clinical trials.

It is well known that the application of ICT in education helps us to develop skills for competent and efficient problem solving in the field of professional activities. This paper aims to examine the attitudes of students towards the use of ICT as a source of education. The methodology adopted was that of original research, with a qualitative and quantitative approach. This study included 175 students from Serbia and Bulgaria. The variables of this study were gender and the years of study. In order to assess the attitudes of students towards the use of ICT in education a five-point Likert scale was used across forty-five statements. The results of the research show that students are very interested in using ICT as a source of education. Thus, it is evident that information and communication technologies have become very important pedagogical resources in approaching the teaching and learning processes in an innovative way.

Published: March 2021

The paper aims to present the conditions surrounding the use of ICTs in Brazilian schools. The goal of the study was to offer a wide perspective that included the opportunities, barriers, transfer of knowledge, and challenges related to introducing information technology into education. The technique used was qualitative - an expert interview with four experienced respondents. The individuals interviewed represented different areas of professional activity: the academic sector, the implementation of practical activities in schools, pedagogical supervision, and the development of commercial software. The study was conducted in 2019, as part of the expert conference CBIE (Congresso Brasileiro de Informática da Educação – Brazilian Conference on Computers in Education). The results of the analyses reveal that the challenges of implementing ICT in educational processes are similar to those found in the global perspective. According to these experts, Brazil faces similar issues to those found in other countries, namely: the appropriate preparation of teachers in the use of ICT, supplying schools with high-speed and up-to-date hardware and software, encouraging teachers to use ICT, the re-constitution of educational policies, and changes in administering IT resources within schools.
