1. BACKGROUND 1.1. Definition and Significance of Management As there is no universally accepted definition for management, it is difficult to define it. Father of scientific management, Frederick W. Taylor gave the following definition: “Management is an art of knowing what is to be done and seeing that it is done in the best possible manner.” A more elaborate definition was given by Henri Fayol (18411925), one of the most influential contributors to modern concepts of management. He considers a management as a process that comprises planning, organizing, staffing, leading or directing, and controlling an organization or initiative to accomplish a goal (1, 2). The verb ‘manage’ comes from the Italian maneggiare (to handle, especially tools), which derives from the Latin word manus (hand). The French word mesnagement (later ménagement) influenced the development in meaning of the English word management, that literally means to conduct, control and direct the affairs of a business, institution, etc. (1). The size of management can range from one person in a small organization to hundreds or thousands of managers in multinational companies. The success of any business depends heavily on the effectiveness of its managers. The significance of management is huge to that point that some people agree that in order to evaluate a company’s current and future worth, the most important factors are the quality and experience of the managers. 1.2. The Difference between Efficiency and Effectiveness Efficiency and effectiveness are both commonly used management terms. These words, while they sound similar and start with the same letters, are often considered synonyms. Yet they both mean different things. Efficiency refers to doing things in a right manner. Scientifically, it is defined as the output to input ratio and focuses on getting the maximum output with minimum resources (1). Effectiveness, on the other hand, refers to doing Professional paper, Received: Apr 05, 2021, Accepted: Jun 23, 2021, doi: 10.5455/ijbh.2021.9.97-104, Int J Biomed Healthc. 2021; 9(2): 97-104

The idea for establishing “EFMI Inside” Newsletter was born in Lyon in August 2019, during “MEDINFO 2019” Conference and EFMI Council meeting, when Catherine Chronaki, Izet Masic, and some other EFMI Council members discussed and concluded to start with magazine in which we can record important and prompt facts and information about past, current and future activities of European Federation for Medical Informatics (EFMI). EFMI has other types of spreading information about important facts of its activities, as “Reports”, but closely for official Council members, as reports of national and other representatives in EFMI. This publication will be an important and useful resource of EFMI and its activities for everybody who wants to be familiar with Medical informatics development and achievements in all areas of this academic and scientific discipline in European countries, but also, worldwide. In the first issue of of “EFMI Inside” readers can find contributions of influential medical informatics persons, former or current EFMI Council members - Presidents or Chairs of Working Groups, Honorary Fellows, and other EFMI members who were actively involved in the development of Medical informatics in their countries, but also worldwide. A lot of facts “inside” of the ”newsletter” was not available and visible on the way like presented in this issue.

The paper discusses the processes of implementation of digital platforms, a special group of network media, in the filed of education. The effects of platform mechanisms on established learning concepts, especially the notion of education as a common good, are critically considered. Special attention is given to the implications of ''pandemic pedagogy'' conditioned by the appearance of the disease COVID-19 on the reconfiguration of previous practices and educational institutions. The paper points to the fruitfulness of the interdisciplinary dialogue of media studies and sociology of education in the analysis of the dynamics and transformation of modern educational systems.

INTRODUCTION Gastric acidity plays an important role in the protection of infants against various pathogens from the environment. The histamine-2 receptor blockers (H2-blockers) are off-labeled drugs that are frequently prescribed in preterm neonates to prevent stress ulcers. The impact of the H2-blockers on the development of the necrotizing enterocolitis (NEC) in preterm infants is still controversial, particularly in the developing world. MATERIALS AND METHODS One hundred twenty-two preterm infants were enrolled in the study. The multivariate logistic regression model was used to identify potential postnatal risk factors associated with NEC. RESULTS Preterm infants (n = 51) with total NEC, medical NEC, and surgical NEC had the highest rate of receiving ranitidine compared with controls (n = 71) (39.2%, 19.6%, and 47.6%, p < 0.05). Logistic regression analysis revealed that ranitidine use and nosocomial infections were significantly associated with NEC development (odds ratios 1.55 and 3.3). CONCLUSIONS We confirm that ranitidine administration was associated with an increased risk of NEC in preterm infants. H2-blockers use should be only administered in very strictly selected cases after careful consideration of the risk-benefit ratio.

Deployable lightweight structures are studied in the disciplines of architecture, civil engineering, aerospace engineering, mechanical engineering and other fields of their application. The research into these structures in individual fields resulted in a large amount of data sorted out by numerous classifications. The previously made classifications proposed by different authors are presented in this paper by the usage of reasonably unified tables that enabled a direct insight into the essential characteristics of these structures, their analysis and mutual comparison. One of the results of these analyses is the proposal for the unified classification given in a separate table in this paper. The results of interdisciplinary studies have been collected into a unified classification which could be applied for the research in different scientific fields, presenting the basic types of these structures, including individual elements and details with their characteristic features. The proposal of the unified classification of deployable structures is made according to the application of the basic elements used for structure forming. The suggested classification, with the review of the results of the present research, is a significant starting point for the scientists in different disciplines and it provides a detailed insight into the studied characteristics of these structures.
