COVID-19 pandemic has put traditional forms of work and education on hold for many institutions. The impact of the transition to "online" work and education mode on mental and education on mental health is particularly interesting. The primary objective of this paper was to to identify advantages and disadvantages of transition to the online work regime that were additionally exacerbated by the pandemic (managerial aspect). The secondary objective was to consider this impact on the mental health of the individuals (socio-psychological aspects). A review of the literature published so far related to the work and teaching process in the Covid-19 pandemic recommends an online regime whenever possible. The results in the labor market domain indicate that if a person is self-disciplined, does not require supervision, has clear tasks and motivation, the online regime provides a number of benefits to such an employee, and consequently to the employer. On the other hand, for people who find motivation to work primarily in contact with colleagues, require supervision, lack self-discipline, as well as for those who aspire to managerial positions, teleworking does not give favorable results. In the field of teaching, in online education, quantitative analysis shows an improved success of pupils and students, but raises the question of whether this success is backed by real knowledge. The identified health consequences for individuals exposed to long-term online interaction regimes are, primarily: burnout syndrome, isolation from friends, problems in family relationships, experience of reduced happiness at home, general poor health and lack of sleep. It is likely that this regime will continue to some extent in the foreseeable future; work organizations and educational institutions will need to implement formalized policies that take into account support for managing the boundary between work and home activities, role clarity, workload, performance indicators, technical support, facilitating networking and training for managers.

The promptness of providing services to patients directly affects the success of healthcare organizations. In this regard, the implementation of contemporary concepts in healthcare organizations is synonymous with success. Subject of research: The subject being researched in this paper is the possibility of applying the SIPOC method to the clinical process in obstetrics. A more precise application of the abovementioned method would mean a prompter implementation of activities within the clinical process (pregestational counseling, antenatal care of expectant mothers, deliveries, supervision of women during puerperium). Through the activities of the abovementioned clinical process, an effort is made to meet the health needs of expectant and new mothers. The application of the SIPOC method is not sufficiently present in clinical processes, especially the clinical process in obstetrics, and therefore this paper opens a new research area. Aim: The aim of this paper is to indicate the relevance of the SIPOC method as one of the tools within the Lean methodology, which can be used to improve the clinical process in obstetrics. Materials and methods: The following materials and methods were applied in this study: the method of analysis, the inductive - deductive method, the method of synthesis, the method of description, the method of proof. Case analysis was also used in the application of the SIPOC matrix at a gynecology and obstetrics outpatient clinic. Results: The results of the research showed that there was a positive impact on improving the efficiency of the provision of health services, through the implementation of modern methods. The SIPOC method affected the improvement of the efficiency of the clinical process in obstetrics. The review of the literature and the obtained results revealed that there is no formalized concept with instructions on the implementation of clinical process improvement methods.

Plant extracts are widely used as biofungicides and medical bioproducts because of their eco-friendly nature and cost effectiveness. The present investigation focuses on the activity of a solvent based on industrial hemp extracts against two phytopathogenic fungi and five human pathogenic bacteria. The present study suggests the potential of the industrial hemp extracts for the development of novel broad spectrum herbal formulations used in plant protection and medicine.

Using natural and modified Ca-bentonite as an adsorbent to observe a satisfactory trend in the removal of heavy metal ions As(V) and Hg(II) from simulated wastewaters. In this original scientific paper, Ca-bentonite was modified in two ways, thermally activated at a temperature of 300 °C for 3 hours and acid activated with HCl and H2SO4, molar concentrations 0,4 mol/L. Ca-bentonite used in this original scientific work was used from the Shipovo mine (Šipovo mine), Bosnia and Herzegovina and proved to be an excellent bioadsorbent for the removal of present ions from simulated wastewaters. Also this is eco-friendly adsorbent and low costed compared to other expensive adsorbents. Due to its chemical composition in which two oxides predominate, namely SiO2 (48.28 mass %) and Al2O3 (23.04 mass%), it can be concluded that Ca-bentonite from the Shipovo mine (Šipovo mine), Bosnia and Herzegovina belongs to the group of refractory materials. The highest removal efficiency of As(V) ions expressed in % was 75.11 at the initial concentration of 1.5 mg/L and was recorded using HCl acid-activated Ca-bentonite. The efficiency of Hg(II) ion removal was the highest using thermally activated Ca-bentonite and this value was 99.66% at an initial concentration of 1 mg/L.

Protests among citizens of Bosnia and Herzegovina are becoming more frequent. Most often, their aim is to decry the dysfunctionality and opacity of the government, which are the result of the ethno-political structure created by the Dayton Agreement, but also a trend towards democratic regression and autocracy. A number of authors have tackled the ?JMBG? protests of 2013 and the Plenums that emerged from the February 2014 protests, from their particular disciplines. The focus of this paper is the social movement ?Justice for Dzenan,? organized by the Memic family upon the tragic death of Dzenan Memic in Sarajevo in February 2016. An in-depth study was conducted with key actors of the movement, as well as those who follow or in some way support the protests. Particular emphasis in the research was paid to the pragmatic symbiosis of the social movement and one political party. We argue that it is possible to identify a pragmatic symbiosis as a novel form (democratic innovation) of socio-political cooperation that can impede rising autocratization. Through the quest for accountability, social movements are introducing new strategic practices of mobilization and a novel type of alliance-building with external factors (new political parties as well as other social movements). The goal of the paper is to explore how the social movement ?Justice for Dzenan? interacts with political parties and approach the political sphere in BiH. Also, the idea is to examine the possibilities and functionality of this kind of cooperation with the framework of contentious politics.

Background/Aim: Sulphur mineral water is widely used in the treatment of musculoskeletal diseases. Hydrogen sulphide is an important regulator of bone metabolism and its application in the treatment of osteoporosis is intensively researched. The aim of this study was to analyse biochemical and histological effects of H2S containing mineral water of "Mlječanica" spring on ovariectomy-induced experimental osteoporosis in rats. Methods: In this experiment a 14-week-old Wistar female rats were used. The animals undergone bilateral ovariectomy (OVX groups) as an experimental model for oestrogen-deficient osteoporosis. After six weeks, animals were divided into control and the experimental group. Rats from the experimental group treated with H2S (SW group) containing mineral water ad libitum during five weeks. Biochemical parameters for monitoring sulphur water effects were concentration in serum of osteocalcin, alkaline phosphatase, calcium and phosphorus. Histological analyses of the left tibia coloured with haematoxylin-eosin were carried out. Results: Regarding the biochemical parameters, a statistically significant increase was observed in the OVX group for osteocalcin, alkaline phosphatase calcium and phosphorus compared to the sham-operated (CNT) group (p < 0.01). In SW + OVX, alkaline phosphatase was statistically significantly decreased (p < 0.01) and serum osteocalcin and phosphorus increased (p < 0.01). Calcium values were increased without significance. In the OVX + SW group, histological analyses showed numerous osteoblasts along the trabecular endosteum and the growth of young chondrocytes in the central bone zone and their migration to the peripheral parts. Conclusion: Drinking the H2S containing "Mlječanica" mineral water has led to decreased alkaline phosphatase, increased osteocalcin and phosphorus concentration in serum and stimulated the bone reparation in osteoporotic rats.

The research sample consisted of 43 first-year male students at the Faculty of Security Studies Banja Luka. This study was conducted to with the aim of determining the relationship between student self-assessment of motor skill performance and the results of the same obtained based on the application of appropriate tests for the assessment of students' motor status. The assessment of motor skills was performed through a battery of seven tests: maximum number of push-ups in 10 seconds (MSKL) - used to assess the dynamic strength of the arm and shoulder girdle, standing long jump (MSDM) - used to assess the explosive power of the lower extremities, agility with a stick (MOKP) - used to assess coordination, the maximum number of trunk lifts in 30 seconds (MPTR) - used to assess the dynamic strength of the trunk, hand tapping (MTAR) - used to assess the frequency of hand movements, forward roll - backward roll - running (MKNT) - used to assess agility, and the Cooper's 12-minute running test (MKUP) - used to assess aerobic endurance. For the self-assessment of motor skills, a constructed questionnaire with six responses was used: excellent (5), above average (4), average (3), below average (2), poor (1), and very poor (0). The obtained results showed a positive transfer of the Special Physical Education (SPE) curriculum to body coordination, agility, and the dynamic strength of the arm and shoulder girdle. Students' self-assessments of motor skills in the test for the assessment of trunk dynamic strength, dexterity and agility were excellent. The students provided poor self-assessments regarding the test for the assessment of explosive power of the lower extremities, speed, and the frequency of movement, the dynamic strength of the arm and shoulder girdle and body coordination. The students provided overestimated self-assessments in the aerobic endurance test. The obtained results indicate the need to enrich the teaching content of SPE, primarily in the area of motor skills aimed at the development of aerobic endurance, as well as the implementation of the self-assessment method in the same.

Introduction. Combustible tobacco smoking accounts for nearly 30% of all cancer deaths in the United States of America and about 7 million deaths worldwide each year. Nowadays, e-cigarettes are increasingly used, especially among young people, but nicotine addiction that develops by such smoking easily converts to smoking combustible tobacco. Therefore, public health efforts must be directed to the prevention of initiation of smoking all nicotine-containing products. Role of Physicians. Medical doctors are very influential in smoking-related changes in local society, especially those who work in primary care, and they have an important role in both prevention and cessation of tobacco smoking. Tobacco smoking should be eliminated among medical doctors, yet many of them still smoke. The lowest percentage of smoking among physicians is in Oceania and North America (less than 11%) and the highest in Eurasia (25%). Smoking prevalence among medical students is higher than 35% in Georgia, Greece, Spain, and Italy, but less than 5% in the United States of America and Australia. In Serbia, 23% of physicians smoke. The age of physicians does not affect the number of smokers, but gender has a significant effect; women smoke less than men. Smoking Prevention and Cessation. Education about the effects of combustible tobacco smoking is a critical issue for successful smoking prevention and cessation; the best way is to provide educational programs on smoking at medical schools by introducing a mandatory course on combustible tobacco smoking at the beginning of the first year of study, especially in societies with a large percentage of smokers. Conclusion. In this paper, we showed how smoking can be eliminated among physicians and how they can affect the patients, public health policies, and antismoking campaigns.

Let me explain the principle of bioassay. It is an analytical method for determination of the relative strength (concentration or potency) of a substance by comparing its effect on a test organism (living animal, cells or tissues) with that of a standard preparation. Bioassays are used in pharmacology mainly to determine the concentrations of hormones or drugs, eg biologically active peptides, acetylcholine, catecholamines, prostaglandins, histamine and prostacyclin. However, there are other forms of bioassay in which one can use isolated tissues and determine actions of their nerves, such as the nerve to the diaphragm from rats. Bioassays may also be done in vivo in individual humans. The assessment of drug effects in humans is designated by clinical pharmacologists as a clinical trial. Such trials often require hundreds or sometimes thousands of patients in order to test efficacy and safety of any new drug before it can be marketed. If the human investigations produce unexpected results, quite different of those obtained in the animal experiments the trials must be redesigned, to examine why and how this occurred. There are many examples of how such discoveries resulted in new clinically useful medications (eg, discovery antihypertensive effect of beta-adrenergic blocking agents).6 Accordingly, the pharmacologists have the bioassays, as a tool, which help them in the discovery process. I wrote on the renowned pharmacologist Professor Ervin G Erdös and his scientific opus in my reminiscence article written on the occasion of his death in 2019.1 When I attended the Fourth International Congress in Pharmacology in Basel in 1969, Dr Ervin G Erdös invited me to join his laboratory. Thus, in April 1970, I arrived in Oklahoma City as a Fulbright Fellow to work with him for two years. Later on, as a visiting scientist I frequently worked in his research laboratories in Dallas and Chicago and we shared research interests through visits across the Atlantic between the former Yugoslavia and the United States.2, 3

Tobacco smoking is a mental and behavioral disease. It causes significant pathology and premature death in more than seven million individuals a year around the globe. Because smoking is such important public health issue, the general public will benefit from targeted preventive strategies. Medical doctors have a vital role in smoking cessation of their patients. Non-smokers are more successful in this role than chronic smokers. Governmental regulation on smoking, as well as strict no-smoke policy in hospitals and university campuses will help not only medical students, other health workers and the general public to quit smoking and contribute to the general good health of this population. The aim of this comment is to analyse the current smoking habits of physicians and medical students and presents policies and other help to the medical students to stop tobacco smoking.

The aim of this paper is to review and summarize the theoretical and empirical facts of using the (BMI), (body mass index) in determining the relationship between body constitution and motor skills. Several key circumstances have been identified in which the body mass index can give erroneous information about the actual body composition, and especially about the amount of adipose tissue in the body. Factors such as age, sex, race, health status and muscle mass can influence the connection between(BMI) and body fat. Due to a relatively low coefficient of determination between (BMI)and percentage of body fat, one should be cautious when using (BMI) to evaluate body composition as a predictor of obesity or as a substitution measure in evaluating the influence of body constitution on the efficiency of motor performances. The analysis of the sources indicates that the existence of unexplained facts uses alternative measures of body composition and their limited use in research and direct training practice. Therefore, new concepts and models are necessary in order to explain the influence of body composition on the efficiency of motor performance. Apart from the necessary evaluation of variables of percentages of fatty and muscle tissues, it could be assumed that the application of two component (BMI) = (FFMI+FMI), (Fat Free Mass Index, Fat Mass Index) and/or (MFR) model (Muscle to Fat Ratio) would provide a better comprehension of these relations.
