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.

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.

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.

In this paper, a novel method for electric field intensity and magnetic flux density estimation in the vicinity of the high voltage overhead transmission lines is proposed. The proposed method is based on two fully connected feed-forward neural networks to independently estimate electric field intensity and magnetic flux density. The artificial neural networks are trained using the scaled conjugate gradient algorithm. Training datasets corresponds to different overhead transmission line configurations that are generated using an algorithm that is especially developed for this purpose. The target values for the electric field intensity and magnetic flux density datasets are calculated using the charge simulation method and Biot-Savart law based method, respectively. This data is generated for fixed applied voltage and current intensity values. In instances when the applied voltage and current intensity values differ from those used in the artificial neural network training, the electric field intensity and magnetic flux density results are appropriately scaled. In order to verify the validity of the proposed method, a comparative analysis of the proposed method with the charge simulation method for electric field intensity calculation and Biot-Savart law-based method for magnetic flux density calculation is presented. Furthermore, the results of the proposed method are compared to measurement results obtained in the vicinity of two 400 kV transmission lines. The performance analysis results showed that proposed method can produce accurate electric field intensity and magnetic flux density estimation results for different overhead transmission line configurations.

This research aimed to determine the differences between the junior (U18) water polo players of five Croatian and one Montenegrin clubs in the anthropometric characteristics and body composition. The first sample of the subjects consisted of 14 players of the water polo club Mladost average age 17.57 ±0 65, the second sample consisted of 11 players of the water polo club Sibenik (17.82±0.65), the third sample consisted of 13 players of the water polo club Primorje (17.23 ±1.01), the fourth sample consisted of 15 players of the water polo club Mornar (17.13 ±0.64), the fifth sample consisted of 13 players of the water polo club Medvescak (17.92 ±0. 6) and the sixth sample consisted of 10 players of the water polo club Jadran Herceg Novi (Montenegro) (17.70 ±1.34). In the 2010–11 season, these clubs participated in Regional Water Polo League, commonly known as the Regional League or Adriatic League in Sou theast Europe. The measurements was conducted in the competition season in the period September-December 2010, at sports centers and swimming pools of water polo clubs that participated in the research. Anthropometric characteristics and body composition were evaluat d using a battery of 12 variables: body height, body weight, arm length, arm span, leg length, foot length, chest skinfold, trice ps skinfold, back skinfold, abdominal skinfold, upper leg skinfold and body mass index. The standard central and dispersion parameters of al l variables were calculated. The significance of the differences between the water polo players of six teams in the variables for ssessing anthropometric characteristics and body composition were determined using ANOVA and an LSD Post Hoc test.Based on the central a nd dispersion parameters, it can be stated that the values of all the variables are highly similar to all of the water polo player s of these six clubs. The ANOVA test found that the water polo players of the six international clubs do not have statistically significant di fferences in the variables for assessing anthropometric characteristics and body composition.
