Published: August 2020

This study aims to determine the perceptions of the use of scientific process skills of in-service and pre-service teachers working in branches related to science courses in secondary and high schools. Therefore, this research was designed based on a relational survey model and was carried out with 150 science teachers in Turkey and 260 pre-service teachers from two different universities. The Scientific Process Skills Perception Scale was used to measure their perceptions of scientific process skills. An independent sample t-test was applied to compare the difference between the perceptions of scientific process skills of in-service and pre-service teachers. The results showed no significant difference between the two groups. The ANOVA results further showed that the duration of teachers’ service did not make a significant difference in their scientific process skill perceptions. The results of this study revealed that in-service and pre-service teachers should be supported with training to reduce their reservations about using scientific process skills.

Students’ Perception on Pedagogical Approaches and its Relation to Exam Performance in Professional Accounting Education
Authors: Mohammed Nor Farizal , Che Kassim Che Fatimah , Ismail Puteh Mariam
Published: August 2020

With the Malaysian government’s aim to increase the number of Bumiputera professional accountants, it is important for institutions to search for efficient ways in delivering professional accounting education in order to improve the performance of students. Despite the suggestion from prior literature to adopt student-centered pedagogy, the issue is still not much explored in professional accounting education. Therefore, the aim of this study is to examine whether students’ perception on student-centered pedagogy and teacher-centered pedagogy are associated with the exam performance in professional accounting examinations. The approach of student-centered pedagogy is to promote students to actively take responsibility of their own journey of learning. This study gathered data from 88 professional accounting students in Universiti Teknologi MARA (UiTM). The results reveal that students prefer teacher-centered pedagogy. The results contrast the findings from western literature, and hence it reflects, the learning environment in Malaysia which is still passive. Additionally, the better perception of students on both pedagogies are positively significant with better exam performance, emphasizing the work of both students and teachers are essential for better exam performance. The emphasis on exam orientation in professional accounting education is seen as a limitation to implement student-centered pedagogy in professional accounting education. It implies that the classrooms in Malaysia are not adept into making a shift to empower students’ responsibility. This study adds value by highlighting the best practice that provides benefit to the professional accounting education in Malaysia.

Published: August 2020

There is a growing interest among higher education (HE) researchers regarding the relevance of measuring quality via the lived experiences of teachers and students. However, relatively few studies have examined more broadly the pedagogical practices and student learning experiences in HE. In addition, there is a minimal study that compared students’ perceptions of learning behaviors with that of their teachers. The current study explores students’ and teachers’ perceptions about the existing pedagogical practices and learning experiences by analyzing each group’s responses and examining similarities and differences between their perspectives. For this, undergraduate students (n = 536) and teachers (n =89) at Jimma University, Ethiopia voluntarily participated in filling out two separate questionnaires. The findings show that university teaching and student learning in Ethiopia face considerable challenges that originated from different sources of influences, including input, process, and outcome dimensions. As the study participants reported, they faced high challenges in teaching and learning mainly due to the shortage of required inputs and processes. The role of pedagogical practices and learning experiences within universities' quality measurement and developing strategies to use such data for continuous quality improvement are discussed.
An Examination of the Rational Model in Business Education in the Greater Bay Area (Guangdong, Hong Kong, and Macau) for Curriculum Revision and Development Aimed at Improving Graduates’ Employability Potential
Authors: Carter Jason Lee , Wu Xuemei
Published: August 2020

The rational action model are techniques and processes of decision-making from data for effective decision-making. Business leaders are strategizing for their futures for their future employment needs in the Greater Bay Area region of Hong Kong, Macau, and the Guangdong province. Tertiary business curriculum revision and development efforts are focused on properly preparing graduates’ productive decision-making skillsets that ultimately increases their employability. This qualitative study examines the perspectives of regional business leaders for the knowledge and use of rational action in their own companies, the need or not for the rational action model in future employment decisions, and their take on the rational model inclusion in business curriculum. The purpose is determining what entanglements rational action has in delivering on business leaders’ expectancies in their employment decisions. The findings indicate a strong use by business leaders of rational action and a desire for new graduates to be proficient in rational decision-making, but without a cohesive expression between the three major areas of how to affect curriculum enhancement efforts. The conclusion is a positive demand for rational models to be included in curriculum revision and development efforts, but dependent on the tertiary institutions themselves for design. Recommendations focus on the rational action model in studies of a similar nature, but focused on other regions where emerging economies are focusing on the business education enhancements.

Authors: Răpan Florian , Răpan Daniela , Stoica Ivona
Published: August 2020

In the last decade, following the climate and environmental changes, the geopolitical and strategic importance of the Arctic Region has grown substantially. Global warming has rendered it more and more accessible from the economic, energetic, commercial and even touristic point of view, but on the other hand, this fact also represents a concern for some global, regional or state actors. Warming in the region has created a new space, important from the point of view natural resources, but a non-governed space, which a series of governments are willing to attribute to themselves. The situation tends to complicate because of territorial disputes, the activity and military presence in the Arctic region have grown, generating a more and more complex competition and rivalry, however this state does not necessarily suggest an imminent conflict. On the other hand, at present, the region does not have a security architecture generating a cooperation dynamics. The paper proposes a synthetic analysis and a prognosis on the possibilities of confrontation in the region, based on geopolitical, economic, military and non-military interests of the actors in the Arctic space in global context, using elements of PMESII matrix.

Therefore, they can be considered as a separate part, but not insignificant, of the business of a functioning market economy. Moreover, they benefit from its own law, including the global economic agreements governing commercial transactions of this type. Public Procurement is an important element of the Internal Market and a basic method of public spending and ensuring the free movement of goods, services and works by domestic and foreign companies. Through the adoption and implementation in the national legislation of the Member States of a package of Directives 2014, a new Public Procurement regime is settled. The Public Procurement Law provides two new awarding procedure. Simplified procedure – may be applied by the contracting authority for the contracts with a reduced value and the Innovation partnership. The above procedures are in addition to the procedures below which were already provided for by the prior legislation. In Romania a simplified procedure is applied for contracts /framework agreements with an estimated value below the above mentioned thresholds but with exceed RON 135,060 for supply and services contracts and RON 450,200 for works contracts. Within a simplified procedure, contract notices are published only in the Electronic System for Public Procurement.
Some Comments on the Highest Attainable Standard of Health
Authors: Belova Gabriela , Pavlov Stanislav
Published: August 2020

The last decades present a significant development of the economic, social and cultural rights and specifically, the right to health. Until 2000, the right to health has not been interpreted officially. By providing international standards, General Comment No.14 on the right to the Highest Attainable Standard of Health has led to wider agreement that the right to health includes the social determinants of health such as access to various conditions, services, goods or facilities that are crucial for its implementation. The Reports of the Special Rapporteur on the right to health within the UN human rights system have contributed to the process of gaining the greater clarity about the right to health. It is obvious that achieving the highest attainable level of health depends on the principle of progressive implementation and the availability of the necessary health resources. The possibility individual complaints to be considered by the Committee on Economic Social and Cultural Rights was introduced with the Optional Protocol to the International Covenant on Economic, Social and Cultural Rights, entered into force in 2013.
Technology as a Support for Constructive Learning
Authors: Duralia Daniela
Published: August 2020

The integration of high technology in education has been the topic of many conferences. Being a new concept, many teachers feel anxious when having to use it, whereas students show much excitement. When choosing to integrate technology in their LES (Learning Evaluation Situation), teachers need to have their pedagogical goals established. As Peter Lindsay puts it, “we do not decide on the technology and let that decision dictate the experience” [1].This paper explores the importance of using technology in a constructive way in ESL (English as a Second Language) or EFL (English as a Foreign Language) classes. Most often the teacher does not manage to provide each student with feedback. Such feedback represents the building blocks in students’ learning process. Most often they become demotivated because they have no idea of how they could improve. Not only is feedback through technology a way to save teachers’ and students’ time, but it also gives the latter the opportunity to use metacognitive thinking. Teacher’s control and guidance in view of overcoming their difficulties is indispensable. While monitoring the students, the teacher intervenes correcting them in view of putting them back on the right track so that they finally follow the trajectory drawn in the LES to obtain the final pedagogical goals.

Authors: Rusu Maria-Lucia
Published: August 2020

The current COVID-19 pandemic has led to a reconfiguration of the social paradigm and has brought about a challenge in terms of social distancing during this critical period. Dynamic and interconnected social networks are prone to the spread of the virus both individually and at the macro-social level. The spread of the disease is controlled by allowing sensitive people to temporarily reduce their social contacts, as an attitude taken due to the presence of the virus in the local neighborhood. The social distancing promoted by governments and public health bodies comes as a method to control the pandemic, in the absence of antiviral drugs or a vaccine. Therefore, the control and management of this network during the pandemic is essential. The paper aims to present and analyze the changes that this measure produces in all sectors of society, globally. Also, it emphasizes the role of the government in implementing the measure and the need for cooperation of the population.

KRATKOROČNA PONOVLJIVOST I UTICAJ PROFILA ŠTAMPE NA PROMENU RAZLIKE U BOJI U ELEKTROFOTOGRAFIJI
Authors: Prošić Tamara , Dedijer Sandra
Published: August 2020

Vremenska ponovljivost štampe predstavlja vrlo bitan faktor za kvalitetnu reprodukciju svakog štamparskog sistema. Da bi se osigurala ponovljivost potrebno je kontrolisati kvalitet grafičkih proizvoda i napraviti pravilan izbor osnovnih parametara štampe. Standardizacija štampe značajno pomaže u pravilom upravljanju štamparskim sistemom i na kraju obezbeđenjem  kontinuiranog kvaliteta reprodukcije.

Kako bi ispitali ponovljivost i uticaj profila štampe na promenu razlike u boji u elektrofotografiji vršen je eksperiment na digitalnoj štamparskoj mašini štampom test karti i merenjem i analizom reprodukovanih vrednosti. Na ovaj način vrši se kontrola štampe i regulišu potencijalne greške u reprodukciji.

Predmet istraživanja ovog master rada fokusiran je na tehnologiji flekso štampe u cilju tretmana crne flekso grafičke boje primenom Fenton procesa, kao i ispitivanje uticaja pojedinih parametara na efikasnost obezbojavanja. Fenton proces predstavlja jedan od najefikasnijih unapređenih procesa oksidacije koji se primenjuje za oksidaciju/koagulaciju voda koje imaju visok sadržaj površinski aktivnih materija kao i mnogih drugih teško degradabilnih jedinjenja. Bazira se na generisanju hidroksil radikala iz vodonik-peroksida jonima gvožđa kao katalizatorima pri kiseloj vrednosti i ambijentalnim uslovima. Tokom eksperimenta ustanovljeno je da koncentracija katalizatora i pH vrednost u najvećoj meri doprinose odigravanju i efikasnosti heterogenog Fenton procesa. Takođe je ustanovljeno da smanjenje pH vrednosti dovodi do povećanja efikasnosti obezbojavanja sintetičkog rastvora crne boje.

Background and Objectives. Patients with cystic fibrosis (CF) have a varying spectrum of clinically significant Aspergillus disease in addition to allergic bronchopulmonary aspergillosis (ABPA). Here we aimed to review the different clinical phenotypes related with Aspergillus growth on the airway culture of patients with CF, we also aimed to investigate the effect of Aspergillus growth on lung function tests.
Method. The medical records of 100 patients with CF who had Aspergillus growth on airway culture within the period of April 2001 and June 2016 were retrospectively analyzed. Age, gender, symptoms, physical examination findings, pulmonary function tests, the diagnosis of ABPA, and airway culture results were recorded for every visit. Patients with Aspergillus growth on airway cultures were classified into different groups as ABPA, Aspergillus sensitization, Aspergillus colonization and Aspergillus bronchitis.
Results. Medical records of 83 patients and 147 sputum cultures were attained from 100 patients. The mean age of the patients was 17.6±7.6 years and the mean age of the first Aspergillus growth in sputum culture was 12.5±6.7 years. At first isolation, Aspergillus fumigatus SC was the most common Aspergillus SC in sputum (76.3%) and 14.5% of these patients required hospitalization. Aspergillus sensitization was diagnosed in 3.6% (n= 3) of the patients. Aspergillus colonization was diagnosed in 18.1% (n= 15) of all patients and led to a decline in FEV1%, FVC% and FEF25-75% which was not statistically significant, furthermore. ABPA was detected in 9.6% (n= 8) of all patients and led to a statistically significant decline in FEV1% (p= 0.02); nonsignificant decline in FVC% and FEF25-75%. Aspergillus bronchitis was detected in 43.4% (n= 36) of all patients and led to nonsignificant decline in FEV1%, FVC% and FEF25-75%.
Conclusion. ABPA is recognized as the most common Aspergillus associated disorder in CF patients and is related to deteriorated pulmonary function tests; however Aspergillus colonization and bronchitis may also be associated with worsening lung function.

Background and Objectives. In this study, we aimed to review the treatment options and long-term problems of patients who were diagnosed with coronary artery fistulae (CAF) in our institution. We also tried to determine the most appropriate time for treatment of this condition.
Method. From 2000 to 2018, the medical records of 56 patients (33 males and 23 females) who had CAF diagnoses were retrospectively reviewed.
Results. The mean age of the patients at the time of diagnosis was 3.9 ± 4.6 years (range, 1 month to 18 years) and the mean duration of the follow-up period was 7.4 ± 4.5 years (range, 1 year to 17.5 years). The right coronary artery (RCA) was the most common origin site for CAF, the left main coronary artery (LMCA) was the second most common origin site whereas the left anterior descending coronary artery (LAD) was the third most common origin site. Catheter angiography showed that right ventricle (RV) was the site of termination for CAF in 23 patients (41.1%) while the CAF drained to the pulmonary artery in 16 patients (28.6%). Transcatheter intervention was performed in ten patients, while CAF were corrected surgically in five patients. Transcatheter intervention was initially attempted in two out of the five surgically-treated patients, but the procedure was unsuccessful. A vascular plug was deployed in six patients, a platinum coil was used in three patients, and a platinum coil with tissue adhesive was placed in one patient using a catheter. Early complications were seen in two patients during transcatheter intervention and in one patient during surgery. There were no instances of death or late complications in patients treated surgically or via transcatheter.
Conclusions. Coronary artery fistulae are usually asymptomatic, and medical therapy with long term follow up is the first line treatment. Fistulae that cause hemodynamically significant shunting, chamber enlargement, or visible symptoms should be closed at an early age. This study shows that transcatheter closure is a safe treatment option for CAF that may be performed with high success. Also, it should be known that surgery may be performed effectively with low rates of complications. Because complications can develop in treated and untreated patients of all ages, follow-up should occur during the patient`s lifetime.

Background. The recently described FBXL4-related encephalomyopathic mitochondrial DNA depletion syndrome 13 (MTDPS13) manifests with severe encephalopathy, early-onset lactic acidosis, hypotonia, developmental delay and feeding difficulty. Less than 100 cases with FBXL4-related MTDPS13 and 47 pathogenic mutations in the FBXL4 gene have been identified thus far. Here, we describe a patient diagnosed with MTDPS13 with two novel variants of the FBXL4 gene.
Case. A 51-day-old male was admitted with the complaint of bloody stool. His physical examination revealed facial dysmorphic features, developmental delay and truncal hypotonia with lack of head control. Laboratory investigations showed anemia, neutropenia, metabolic acidosis with hyperlactatemia, elevated fumaric acid, 2-ketoglutaric acid in urine and elevated alanine level in plasma which were consistent with mitochondrial dysfunction. Brain magnetic resonance imaging (MRI) showed large ventricles, thin corpus callosum and poor myelination. Drug-resistant epilepsy developed during the clinical follow-up. Ketogenic diet was initiated for intractable epilepsy; which was then interrupted due to severe metabolic acidosis. Compound heterozygous pathogenic variants were detected in the FBXL4 gene [p.Gly258* (c.772G > T, Exon 5)/p.Trp354Ser (c.1061G > C, Exon 6)] with whole-exome sequencing.
Conclusion. We detected two novel variants of the FBXL4 gene. To the best of our knowledge, this is the first case in the literature that presented with gastrointestinal bleeding as an encephalomyopathic form of mitochondrial DNA depletion syndromes and for whom ketogenic diet was initiated due to intractable epilepsy, which was not reported in previous cases.

Background. Herein we present our experience with abatacept in a patient diagnosed with primary focal segmental glomerulosclerosis (FSGS) and resistant to steroid and other immunosuppressives.
Case. A 17-year-old girl was diagnosed with idiopathic nephrotic syndrome (NS) at the age of 8 years. Kidney biopsy was performed when she did not respond to 6-weeks of steroid (2mg/kg) therapy followed by three doses of pulse methylprednisolone (PMP) and considered as steroid resistant NS. The biopsy revealed focal segmental glomerulosclerosis (FSGS) and cyclophosphamide was added to the steroid treatment but the patient had no response. The genetic analysis revealed G34G/A318A compound homozygous synonym aminoacid variation in NPHS2 gene, thus all immunosuppressive regimes were stopped and she was put on supportive treatment. Throughout this period, she had nephrotic range of proteinuria, however serum albumin levels were > 3g/dl. At the end of two years, the patient had NS with severe edema and hypoalbuminemia. When the genetic analysis was interpreted again, it was found to be consistent with a polymorphism rather than a mutation. Following 3 doses of PMP, oral steroid treatment was resumed and cyclosporine (CsA) was added to the treatment at the fifth year of follow up. However, she was unresponsive to CsA at the end of the first year as well as mycophenolate mofetil used for 12 months and rituximab used for 6 months, respectively. Then abatacept was instituted and proteinuria decreased below 1 gr/day and serum albumin levels increased to 3 g/dl at the end of 6 doses. Serum albumin levels remained stable in the following 7 months.
Conclusion. Partial remission including the decrease in proteinuria and increase in albumin levels achieved in our patient encourages the usage of abatacept in patients who do not respond to multiple immunosuppressive therapies.
