Dr. Eva Haljecka, a Jew of Polish origin, was born on 1869 in Poland, died on 1949 in Yugoslavia, Belgrade, was the first woman surgeon and gynecologist-obstetrician in Serbia and Yugoslavia. Carried out on 1910 the first caesarean section in Niš. She was a duty manager in district hospital in Niš in three occasions - during the Balkan wars, in the World War I and after the World War I. Dr. Eva Haljecka was the first woman doctor of that time in Serbia who seek the full equality beetween male and female doctors and she was awarded for that. German newspaper Illustrirte Zeitung wrote about her and also about other women doctors - Draga Ljočić, Darinka Maletić-Banković, Marija Vučetić-Prita and Ljubica Đurić. Dr. Eva Haljecka accepted Serbia as a new homeland and made it for her all that he could.

Coronavirus disease 2019 (COVID-19) is a severe infectious disease of the respiratory system with clinical signs of severe acute respiratory syndrome. The causative agent is coronavirus 2 (SARS-CoV-2). Common symptoms of COVID-19 pneumonia are fever, cough, shortness of breath, myalgia, expectoration of sputum and sore throat. The X-ray image of COVID-19 pneumonia has its own characteristics and changes with the evolution of the disease. At the beginning of the disease, the radiological finding in the lungs may be normal or changes may be visualized in the lungs in the form of multiple hazy vaguely delineated shadows, which occur gradually, discreetly and modestly, and in the later stage confluence into larger first irregular patch formations, then they grow into a massive irregular shadow of the intensity of the frosted glass, only to diffusely cover the whole lung. Inflammatory changes are usually bilateral, less often unilateral localization, predominantly in the middle or lower lung field, on the periphery along the chest wall and / or supraphrenic. The aim of this paper is to present an X-ray image of COVID-19 pneumonia and our experiences in the X-ray diagnosis of this disease. The material of the paper consists of selected digital radiographs of the lungs and heart and CT of the lungs with pneumonia COVID-19 in 220 patients, which are during the COVID-19 pandemic from April to July 2020. were examined in covid rendgen CC Niš. The results are presented illustratively. Conclusion: The X-ray examination methods in the diagnosis of COVID-19 pneumonia are sovereign, dominant and unrivaled, and the knowledge of the authors and collaborators and the experience gained through many years of work in the profession and co-X-ray are of crucial importance.

It's common for the syndromes indicate to the author or authors who discovered them. The paper aims to show the image of X-rays and ophthalmic syndrome and to point out to those who can be recognized by the proper radiological and ophthalmologic examination. The work is based on knowledge and experience of the author and co-author of the acquired long experience in the profession, acquired many years of ophthalmology and radiological material, the papers presented in the relevant national and international journals, history and local and foreign literary press. Are shown in - Syndrom Stuger-Weber-Krabbe, Syndrome Wyburn-Mason, Syndrome Von Hippel-Lindau, Syndrome Crouzon, Syndrome Apertand Syndrome Saethre-Chotzen. The authors conclude that ophthalmic syndromes have their own specificity in radiologically-ophthalmologic image.

Mind colonization has been a burning issue in the last few decades in the fields of science and humanities. It is argued that mind colonization of the indigenous populations has been conducted via education and language in the mission of ‘civilizing’ since education and language carry culture specific sets of meaning, including knowledge and truth which condition our perception of the world. Zitkala-Ša is one of the earliest Native American authors and activists who sought to subvert the epistemological hierarchy imposed through mind colonization. Zitkala-Ša’s autobiographical collection of short stories titled American Indian Stories (1921) documents her boarding school experience and the acquisition of the colonizer’s education and language. The present paper seeks to address mind colonization through language and education on the example of Zitkala-Ša’s American Indian Stories relying on a number of theories and approaches. The paper also reflects on the importance of Zitkala-Ša mastery of the colonizer’s language

One of the most important characteristics of the special (military) vehicles is possibility to move off-road. In order to achieve appropriate possibility characteristics, military vehicles need, beside other things, to fulfil geometric parameters of vehicle, traction characteristics, stability and ability to overcome obstacles of low load-bearing capacity. The contact between tire and ground is very significant for ensuring adequate performance of motor vehicles and great attention must be paid to it. With that in mind, this paper has developed and illustrated the method for calculating specific tire pressure on ground with use of image processing theory.

The main paper goal is to create an adequate trend model by applying a quantitative research method, i.e. trend analysis that will enable prediction of apple production in the Republic of Srpska for a three-year period (2019-2021). Trend analysis involved the use of linear, quadratic and exponential trend models. Prediction is based on data time series for the period 1998-2018. Gained results show that although the unstable production it could be expected the growth of total production and number of apple trees, while apple yields are expected to decline in the observed period. Obtained results can serve for strategic approach in further development of this sector of fruit production.

The aim of the authors was to create an adequate trend model that would be able to forecast the results of potato production in Bosnia and Herzegovina for a three-year period (2019-2021) by using quantitative research method and trend analysis. Data collected during twenty-seven years (1992-2018) were used for forecasting, and the research results have indicated that the farming area and production of potato will decrease, while yield will be the only parameter of potato production that will show the tendency of growth in the obserevd three-year period. The obtained research results can be used for making strategic decisions related to the development of this branch of agricultural production.
