This paper presents the use of Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method to determine the optimum process parameters in plasma arc cutting of stainless steel. Two input process parameters, cutting speed and plasma gas pressure are considered and experiments are conducted based on Taguchi L9 orthogonal array. After performing the experiments, the surface roughness, cut perpendicularity and kerf width are measured. The analysis of variance (ANOVA) are performed in order to identify the effect of each input process parameters on the output responses. The results indicate that TOPSIS method is appropriate for solving multi-criteria optimization of process parameters. Results also showed that cutting speed of 2500 mm/min and plasma gas pressure of 6 bar are the optimum combination of process parameters.

Aim: Aim of article was to evaluate knowledge and practice of authorship issues among the academic population in the medical field. Material and methods: Article has an analytical character and includes 69 academic workers (from the medical field, with the status of a regular employee of the Faculty of Medicine or a professional associate) who responded to the survey. Results: Within the total number of respondents in the study, 34.8% of them were added as coauthors, although they did not have any input in the writing process. Even 47.8% of the respondents were under psychological pressure, that they have to add their superiors to the list of authors, though they did not have any contribution at any stage of the article preparation, while 29% of the respondents had a tacit agreement about mutual adding to the author’s list, and 36.2% added their superiors to the author’s list, in order that the first author would get a permission to publish the article in a certain journal. Conclusion: The relationship between the author, the mentor, the data processing person, the person providing the moral support etc. must be established, and not all of them has a place in the list of authors, they should be given special places at the end of the article, a space for acknowledgments, where these people may be mentioned. The consciousness of the academic community must change for the purpose of the concrete progress of the academic community and the scientific contributions of its members.

The development of medical informatics goes back to the second half of the twentieth century with the start of the automation of processes. Medical informatics education plays an important role in the education of health care providers and medical providers. Education in medical informatics is not only important for medical students but also for other medical staff at all professional levels of education. Integrating medical Informatics into the full spectrum of medical education is a vital step required for the understanding and practice of modern medicine. There are curricula in the field of medical informatics at many universities in Europe. Great roles in this field had the International Medical Informatics Association (IMIA) and – the European Federation for Medical Informatics (EFMI). Working groups of IMIA and EFMI defined and recommended concepts and methodologies of education for medical informatics on three levels. Generally in all European countries medical education at universities is organized on the basis of the Bologna concept, which has improved the quality of teaching process in plenty matters, but it has brought a big number of highly educated staff, that are younger than average, but also have average level of knowledge. Basically, the Bologna system has brought averageness we tried to escape from. With the introduction of the Bologna process in Bosnia and Herzegovina and other countries, a new process is being introduced which introduces a new curriculum, a greater number of subjects, a complemented systematization of knowledge and the need to correct past attitudes. Since the curriculum of medical informatics varies between countries and universities and faculties in the country, it is necessary to take steps towards the unification of the curriculum at the international level. Aim of the article is to show the status of medical informatics education in Bosnia and Herzegovina and Europe.

Robert Steven Ledley (1926-2012) is one of the most influential Medical informatics scientists in the history of development of Medical informatics (1-3). Robert S. Ledley and his colleague Lee B. Lusted (1922-1994) wrote a seminal 1959 paper in Science that many people cite as the publication that launched the informatics field (Reasoning Foundations of Clinical Diagnosis).

An assessment of the effectiveness of inertization of coal dust with inert dust is an important step in prevention of coal dust explosions. According to the tests on their explosive properties, coal dusts from all the mines in Bosnia and Herzegovina present an explosion hazard. The measure applied in order to prevent the transmission of deposited coal dust explosion, in both methaneous and non-methaneous pits, is wetting. The prescribed content of solid non-combustible particles in coal dust which makes the dust non-explosive (defined by BH regulations)  is based on the figures taken from Polish regulations. In order to get the content of inert component in coal dust which will prevent the transmission of explosion, relevant for BH coals, a research was conducted on brown coal dusts from the three largest producing coal mines in BH. In this case, limestone rock dust was used to inert coal dust. Tests were conducted in accordance with the methods defined by EN 14034-1 and EN 14034-2. The tests conducted indicate that the content of inert component in BH coal dusts differs from the amounts defined by the adopted Polish regulations and, consequently, that BAS (Bosnian and Herzegovinian) standards need to be changed accordingly.

The medieval heritage in the context of cultural and historical tourism in Bosnia and Herzegovina is often neglected, but the practice of other European countries shows that this segment of history can be exploited on a very high level. This is primarily related to large objects in the form of fortresses, which generally have a dominant position over the surrounding area. In Bosnia and Herzegovina there are a large number of such forts (over a hundred), which testify to the turbulent medieval past. The fact is also that a large number of such facilities are in an inadequate state, but there are also those who may or already have their tourist function. Within this paper, four examples of medieval forts in Bosnia and Herzegovina - two in the Bosna River valley and two in Northeast Bosnia, from the aspect of their tourism attractiveness and degree of valorization have been analyzed. The methodology in this paper is based on detailed empirical research conducted through very extensive field observation, with the application of combined qualitative and quantitative comparative method of tourism valorization. The particular method used in the paper was based on the application of GIS cartographic models for adequate spatial representation of the study objects.
