Background: Scientific researchers in the field of biomedicine have the role to interact through published articles in the scientific journal or presentations at scientific and professional conferences because on this way they can affect to the practices that can make people healthier and more satisfied with outcomes of health care systems. For this reason, scientists are encouraged, especially young ones, that after complete the project and finalyze their research investigation to publish scientific work outcomes in a professional and scientific journals. Objective: The aim of this article is to present the current tools available in scientometry for the evaluation of scientific validity of published articles and explain the purpose and, also, to describe the role of important indexed database in dissemination knowledge through the biomedical journals. Methods: Author searched the most influential on-line databases and analyzed deposited papers within the topic scientometrics and used descriptive method of reviewing important facts about experiences with scientometrics in the scientific and academic practice. Results and Discussion: Bibliometric methods are used for quantitative analysis of written materials. Citation provides guidelines for scientific work, because it stimulates scientists to deal with the most current areas of research, and organizes scientific article at the world level, or shapes and directs it. Citation is influenced by: article quality, understanding of the article, language in which the article is written, loyalty to a group of researchers, article type, etc. Some of the indicators used in the evaluation of scientific work are: Impact factor (IF); Citation of the article; Journal citations; Number and order of authors, etc. Impact Factor is the number of citations of articles published in the journal during the previous two years divided by the total number of articles published in the journal during the same period. Factor of influence depends on: the quality of the journal, the language on which it was printed, the area it covers, the journal distribution system. Conclusion: In this article we pointed that h-Index and Google Scholar indexes presents one of a set of valuable measures to determine scientific excellence. Although the h-Index is a better measure than a citation impact factor (IF), it is still based on the opinions of other authors. Since research in medicine can affect the improvement of clinical and public health practices, it is necessary to conduct them. Only quality research with exact results offers the scientific community new information about the examined problem, and the researcher personal satisfaction, the possibility of communicating and conducting scientific dialogue with other members of the academic community, and opening opportunities to receive critical review of those who have insight into the research.

<abstract> <p>Newton's identities of an infinite polynomial with complex-conjugate roots <italic>n</italic>^{<italic>−(</italic>σ+<italic>it</italic>)} and <italic>n</italic>^{<italic>−(</italic>σ<italic>−it</italic>)} are multiple zeta functions for <italic>n</italic>∈[1, ∞), σ∈R and <italic>t</italic>∈R. All Newton's identities can be represented by Macdonald determinants. In a special case of the Riemann hypothesis, the multiple zeta function of the first order is equal to zero, ζ(σ+<italic>it</italic>)+ζ(σ−<italic>it</italic>) = 0. The special case includes all non-trivial zeros. The value of the last, infinite multiple zeta function, in the special case, changes the structure of the determinant that can be calculated. The result is the reciprocal of the factorial value (<italic>n</italic>!)⁻¹. The general value of the infinite multiple zeta function is calculated based on Vieta's rules and is equal to (<italic>n</italic>!)^−2σ. The identity based on the relation of the special case and the general case (<italic>n</italic>!)⁻¹ = (<italic>n</italic>!)^−2σ is reduced to the equation −1 = −2σ. The value of the critical line for all non-trivial zeros is singular, σ = ½.</p> </abstract>

Smoking is a global public health problem, and control measures should be implemented in the community so as to reduce the number of smoking-related diseases and healthcare costs. Community pharmacies are ideal places for providing tobacco cessation counselling as a type of public health service, because they are the most accessible health facilities with direct contact with patients. We aimed to examine attitudes towards the implementation of such services, conducting surveys on a sample of pharmacy students (N=300), community pharmacists (N=383) and the general public (N=987) in the Republic of Serbia. The introduction of smoking cessation services at pharmacies was supported by pharmacy students (59.7%), pharmacists (49.2%), and the general public (36.7%). No difference was found between pharmacistsàttitudes in terms of their gender, age, level of education and years of experience. We found evidence that pharmacists as public health practitioners were recognized mostly by students (94.3%). The majority of them (86.3%) recognized the need for additional education in order to implement new services, and every third pharmacist recognized a gap in their education. The data indicate the need for directed research in order to explore the educational needs and competences for practicing pharmacists and enable them to perform services such as smoking cessation in the future.

The most significant characteristic of the investment interventions that are the subject of this paper is that their activation periods are one year and that their cash inflows are one-time. If there are several independent operations of this type, all those with a positive net present value, and therefore an internal rate of return that is higher than the actualization rate, will be accepted. In the case of competing operations (at certain rates of actualization), especially those whose exploitation periods are different, we may have the case that one of them is better from the aspect of net present value, and the other from the aspect of internal rate of return. The decision on their proper ranking must be based on determining the net present value for exploitation periods that are mutually equal. In the paper, we analyzed two ways of equalizing exploitation periods, the method of reciprocal interventions and the method of replacement, and obtained relevant information for their ranking, which was also confirmed by the annuity method.

Eating disorders affect both the physical health, but also the psychological and social aspects of life of the people who suffer from them. The World Health Organization (WHO) uses the term "quality of life" to define the individuals' perception of their position in life in the context of their culture and values, and in relation to their goals, expectations, standards and concerns, to express a wide range of changes in the life of a person. Some of these changes are either caused or affected by eating habits that often present in a form of eating disorders. In recent decades, there has been growing interest in finding adequate questionnaires to help identify and measure the severity of eating disorders, as well as the quality of life of these patients. Several studies have been conducted on this topic, and scientific evolution and progress will be discussed in detail below to identify the most appropriate questionnaire to assist clinicians in their therapeutic practices. The primary objective is the detailed identification and classification of eating disorders in line with the most recent findings. The secondary objective is identification and classification of the questionnaires for testing eating disorders and quality of life. We conducted a review of the current research into developing the possibility of detecting eating disorders and potential health risks in untreated patients. The following index data bases were digitally searched: PubMed-Medline, Web of Science, Scopus, Cochrane database of systematic reviews, Embase, Epistemonikos, all searched up to August 2022. The combination of keywords revised in the list of medical subject headings (MeSH) was used to select relevant articles: (eating disorders) and (tests and/or questionnaires for eating disorders and quality of life). The analysis included meta-analyses, systematic reviews and original scientific articles. Special attention was paid to the discussion on identifying and providing insight into eating disorders in line with the latest findings, as well as to the examination and description of questionnaires for exploring eating disorders and quality of life. Among the first questionnaires used in practice to assess the quality of life of patients with eating disorders were Short Form-36 (SF-36) and the Eating Disorder Examination Questionnaire (EDE-K). Although generic questionnaires were applied and had produced good results, there is still no specific questionnaire on the quality of life of persons with eating disorders. New discoveries emerge as the search continues for highly specialized and sensitive questionnaires. Several instruments and questionnaires are used to get a final result in several studies investigating the connection between the intensity of symptoms caused by eating disorders and the quality of life, which shall be discussed below. Great progress has been made in evaluating and designing appropriate questionnaires to help clinicians and researchers in diagnostics, developing treatment strategies and providing prognoses for eating disorders, as well as in assessing the quality of life of these patients. Most studies and research come to the conclusion that a combination of multiple questionnaires simultaneously is the best choice for detection and prevention of deterioration in the quality of life of patients with eating disorders, as well as for considering the predictive factors that pertain to the quality of life. It is important to emphasize frequent comorbidity of other mental illnesses, such as depression and anxiety, meaning that it is important to use instruments that help in early detection of these comorbidities during examination.

The discussion about whether the internet addiction disorder should be considered a primary addiction disorder or a secondary disorder due to other psychiatric illnesses is a very current topic. Although the term "addiction" has historically been associated with the pathological use of psychoactive substances, research over the past few decades indicates that various behaviors are also part of the spectrum of addiction. Accordingly, addictions to psychoactive substances and behavioral addictions overlap in several segments, but there are also certain differences between them. Taking into account these statements, the subject of this research was the analysis of the personality structure of Internet addicted adolescents, aimed at identifying if there are specific differences in certain personality dimensions between adolescents addicted to the Internet (reference group) and adolescents who abuse psychoactive substances, as well as in adolescents from the non-clinical population. The methodology was applied to a sample consisting of 125 respondents of both genders, aged 13 to 24, of whom 27 were from the clinical group of Internet addicts, 24 from the clinical group of psychoactive substance addicts, and 74 from the non-clinical population. A questionnaire was used for assessing Internet addiction (Internet Addiction Test) and a questionnaire for assessing the personality of adolescents (Belgrade Personality Inventory of Adolescents). The results indicate that we cannot talk about a specific profile that distinguishes respondents who are addicted to the Internet. However, despite the limitations, significant differences in certain dimensions indicate certain deviations between groups of adolescents with Internet addiction, addiction to psychoactive substances and the non-clinical population. Low research curiosity, poorly developed perseverance and goal orientation play a significant role in the aetiopathogenesis of Internet addicts. We conclude that the obtained results can have a significant role in solving the current dilemma whether Internet addiction disorder should be considered a primary addiction disorder or a secondary disorder due to other psychiatric diseases.

The authors analyse the peculiarities of contracting in the business of vessel leasing in the Republic of Croatia and its relation to other movable properties. General business conditions as part of the vessel leasing contract are the focus of this research. In the paper, the authors examine different approaches of leasing companies in relation to the specifics of the vessel, as an object of leasing, which, through the general conditions of business, determine the specific rights and obligations of the leasing provider and receiver. A critical review is given of the various solutions that are prescribed by leasing companies in the Republic of Croatia through the general terms of business. For a complete analysis of the scope of the parties in the contracting process, the legal framework of the leasing contract is analysed beforehand.
