ADAPTATION AND PROGRESS THROUGH CHANGE MANAGEMENT

The technological progress, digitization and the explosion of information significantly change how individuals, the business environment, and society act, develop and add value. New, interdisciplinary approaches, constantly adapted and sustainable both at the micro and the macro levels are required. Within a company, change management is a systematic element of the strategic business process and involves the early identification of the opportunity of the employees’ development, courage, commitment and flexibility; under no circumstances should it be seen as a risk and instability factor, as it may be considered in the early stages. The example presented in this article proves that the openness to change and continuous improvement develops advantages, optimizes processes and sustains long-term progress

ECONOMIC IMPLICATIONS OF SEVERAL SPECIAL PROPER NOUNS

Our ability to function in today’s social and economic world is mightily affected by our language skills and word knowledge. A spoken language is dynamic, its vocabulary being enriched by new words all the time. A special category of lexical creations are the eponyms and the antonomasias, linking various fields: literature, history, mythology, economics, marketing, law etc. A brief analysis of some of these proper names, now common nouns, shows us that poor interdisciplinary knowledge makes the understanding of a text almost impossible. Eponyms and antonomasia are met in everyday language. Their study yields a fascinating insight into the rich heritage of the languages and their development. From a legal and an economic point of view, these phenomena have affected the right of a trademark since becoming legal. It is true that finding a name for a new product is a risky approach, particularly from the financial point of view. The paper provides examples and discusses the most important aspects implied by these linguistic issues.economic phenomenon, brand risk, linguistic phenomenon, lexical creations

On certain surfaces in the Euclidean space E3{\mathbb{E}}^3

In the present paper we classify all surfaces in \E^3 with a canonical principal direction. Examples of these type of surfaces are constructed. We prove that the only minimal surface with a canonical principal direction in the Euclidean space ${\mathbb{E}}^3$ is the catenoid.Comment: 13 Latex page

Premature ventricular beats in school-age children

Introduction. Premature ventricular beats (PVB) have been described in 40–75% of apparently healthy persons as detected by 24–48 hour ambulatory (Holter) ECG recordings. This decreases in 10% of young children and school-age children and increases in 20% -30% of normal adolescents. Pediatric studies have shown that in some asymptomatic children, an increase in the frequency of PVB can cause ventricular dysfunction and arrhythmogenic cardiomyopathy. Aim of study. Clinical-paraclinical evaluation of PVB in children with normal structural heart. Methods and materials. A descriptive analytical study was performed, which included all children of both sexes of school age (7-18 years), hospitalized consecutively in the pediatric cardiology service of the Mother and Child Institute for a period of 3 years (2019-2021). The data of the patient files were analyzed, including the results of instrumental investigations, such as standard 12-lead ECG, Holter ECG monitoring (24 hours), and echocardiography. Results. The study group included 55 children of both sexes, with a prevalence of boys (62%). From the general group, the vast majority (50 ptc, 90,9%) of children had PVB on a normal structural heart. Analysis of ECG pathways and Holter ECG protocols determined the prevalence of PVB in 16 (32%) children and 7 cases with combined extrasystoles (PVB and premature supraventricular beats, SVPV). It should be noted that in a significant number of patients (15 children) there was a combination of PVB with other arrhythmias, including 5 children with AV block and 1 case with long QT syndrome. Performing the ECG test with effort showed the disappearance or thinning of PVB in most patients, only in 4 children the test induced arrhythmia. Echocardiography performed in all patients in the study confirmed the presence of arrhythmogenic cardiomyopathy criteria in 6 (12%) of cases (dilation of the left or right ventricular cavity ˃ 2 z score, decreased ventricular ejection fraction ˂ 60%). Regardless of the symptoms, both patients with cardiomyopathy and children with frequent, polymorphic and allorhythmia type of PVB or SVPB administered chronic antiarrhythmic treatment, mainly beta-blockers (83.9%) of the 2nd or 3rd generation. Evaluation of patients at 2.5-3 months confirmed the efficacy of treatment by clinical ECG and echocardiographic improvement. No side effects have been reported. Conclusion. PVB is frequent asymptomatic arrhythmia in school-age children. Some children (12%) may evaluate with ventricular dysfunction or cardiomyopathy. Beta-blockers may be used for symptom control and improve systolic ventricular function
