The fact that since March 2018 Agile is included in the Project Management Body of Knowledge (PMBOK), indicates the importance of this methodology in project management. Scrum as the one of the most accepted Agile forms emphasizes the importance of Scrum Master who has many responsibilities: teaching, coaching, mentoring the team, removing impediments, acting as a protector of the team, etc. However, many companies assign this role as additional work to a team member, a project manager or even to an executive. Guided by the impression that the role of Scrum Master is not fully recognized and appreciated, this paper will attempt to determine the potential risk of not having a dedicated Scrum Master within an agile team. As a research tool, we used interviews and online surveys with employees of companies that use Scrum.

The purpose of this paper is to bring to light the biographical details, the professional work and the publishing activities of Bogusławą Keckovą (Bohuslava Kecková in Czech and Keck in German), who functioned as an Austro-Hungarian health officer in Mostar from 1893 to 1911 during the period of the Austro-Hungarian occupation of Bosnia and Herzegovina (BH). Keckovą, who came from Prague, was the second of nine female physicians to be employed by the Austro-Hungarian authorities between 1892 and 1918. Keckovą contributed significantly to the improvement of public health and hygiene in BH, especially by organising the medical treatment of Muslim women. She published a series of popular medical articles, both in Czech and in Bosnian. Her medical articles in the Mostar newspaper, 'Osvit', were among the first in BH to promote public health education and aimed at improving the health of the population. In the Czech Republic, 'Bohuslava Kecková' is renowned for being the first Czech female physician to graduate, who, due to Austria's conservativism and anti-feminism, had been forced to study and practise abroad. After Keckovą's efforts to have her Swiss MD degree (1880) recognised in Austria failed in 1882, she acquired an Austrian midwife's diploma and established a maternity home in Prague. In 1892, she accepted the invitation to serve as an Austro-Hungarian female health officer in Mostar, where she initialised and popularised the utilisation of public health among (Muslim) women. CONCLUSION: Bogusławą Keckovą's work as a physician, medical writer and health educator, which she continued tirelessly until her death in 1911, was based on gender-specific socialmedical concepts, which were at the core of the contemporary Czech feminist movement.

Introduction: Achilles tendon injuries usually occur with abrupt movements at the level of the ankle and foot, and the consequence is the overload of the Achilles tendon. Aim: Examine the Achilles tendon load as a function of the landing angle, and find the critical point at which the tendon overload begins and when a further increase in the landing angle can lead to rupture. Methods: The study has a prospective character. The input data represent the anthropometric values of the respondents, who are professional basketball players in the senior national team of Bosnia and Herzegovina and were processed in the CATIA v5-6 software solution. Software data processing analyzed the landing angles and the transfer of force to the Achilles tendon. The end result is a regression curve, which projects the angle at which the Achilles tendon is overloaded, and indicates an increased risk of possible injury to the tendon itself. Results: The onset of overloading starts at an angle of 32.28° and at an angle of 35.75° the overloaded load occurs, indicating the need for the subject to change the position of the foot to prevent damage to the tendon itself. Conclusion: An angle of 35.75° is the critical point at which the Achilles tendons are overloaded at the very landing. Prevention of injury should go in the direction of practicing the feet for a particular position at the time of the landing, and in the direction to develop adequate footwear that would mitigate the angle at the landing.

In order to support modern business environment, software engineering has a constant tendency to increase productivity and thus the quality of the software. When recruiting, a biography can tell a lot about an individual, about expertise to do a certain job, but that is often not enough. For this reason, a model for prediction of work habits based on personality types has been introduced in this paper. Through the results of the research, by analyzing the employees of the FitSoft company (Bosnia and Herzegovina), a statement has been made of the existence of a certain correlation between the types of personality and the way they perform their tasks. The purpose of testing personality types is to determine how an individual performs their daily activities, and which features give them the advantage of choosing and performing certain jobs. A proposed model for predicting employees’ habits inside agile software teams based on personality estimates should present a clear insight of all factors that are related to employees, their productivity and business results.

Aim To identify short-term effects of extracorporeal shock wave lithotripsy (ESWL) on renal function in children and adolescents with single kidney stones. Methods In a 4-year period 30 children (15 boys and 15 girls) from 10 to 18 years of age were treated for unilateral renal stones with ESWL. Inclusion criteria were: up to 18 years of age, kidney stone (from 4 to 20 mm in diameter) visible on X-ray, first ESWL treatment, unilateral lithotripsy treatment without previous kidney surgery, patients without infravesical obstruction, patients without proven urinary infection, repeated use of one (the same) analgesic, patients without anticoagulant and antihypertensive therapy, patients without use of nephrotoxic drugs prior to and during the treatment, normal blood pressure, non-pregnancy patients with normal renal function. Serum enzymes (alkaline phosphatase, lactate dehydrogenase), cystatin C, serum and urine electrolytes (sodium, potassium, chloride), and urine neutrophil gelatinase-associated lipocalin (uNGAL) were tested before, on the first and fifth day after the treatment. Results An increase of alkaline phosphatase and lactate dehydrogenase was statistically significant on day 1 (p<0.05) and values returned to normal on day 5. Serum cystatin C level was also significantly increased during the first four days after ESWL treatment (p<0.05) and returned to baseline on post-treatment day 5. There was a statistically significant difference in the level of uNGAL in urine before and 24 hours after ESWL treatment (p<0.05). Conclusion The ESWL is a safe and curative procedure for the treatment of kidney stones in children and adolescents with no evidence of serious adverse effects on renal function.

Aim To compare hospital costs of acute limb ischemia treatment in two periods of time and to show evidence of long-term repercussions on reducing costs during successful treatment. Methods Retrospective analysis of data obtained from 100 patients' medical history in the period 2000-2016 at the Clinic of Vascular Surgery Sarajevo: group A - 60 patients with acute limb ischemia in the period 2005-2016 and group B - 40 patients with acute limb ischemia (ALI) in the period 2000-2005. From 2000 to 2005 conservative treatment method was used, invasive diagnostic and surgical procedures were often delayed for a shorter or longer period of time. During the period from 2005 to 2016, the management model and safe practice included emergency diagnostic procedures, colour-Doppler, arteriography, emergency surgery (embolectomy by Fogharty and if necessary, vascular by-pass). Results Better health service for the patients with acute limb ischemia was offered in the period 2005-2016, which relied on proven medical treatment trends. The largest share of the total costs of each patient included costs of hospital bed with significant difference between the period 2005-2016 and 2000-2005, mean of 1398.71 KM and 2480.45KM, respectively (p<0.0001), indicating rationalization of time that patients spend at the Vascular Clinic. Conclusion This trend of money/fund savings is an example of good practice, effectiveness and efficiency in the treatment of ALI and as such was used in patients with other vascular diseases.

More than 200 men were killed at the Korićani Cliffs on Mount Vlašić in central Bosnia during the Bosnian war. The location of this mass grave remained unknown for a long time following the war, until 2008, when the Missing Persons Institute discovered a site containing the remains of approximately 60 individuals. Later, in September 2017, a new mass grave was identified at this location that had not been robbed and skeletal remains remained close to the location where the victims had died. This grave was also unique, by definition, as it was a primary inhumation site, but with a high degree of commingling and disarticulation, typical of secondary inhumation locations. The exhumation team found the first remains in this grave approximately one and a half meters beneath the rocks, while the extent of the commingling resulted in necessary modifications to standardized exhumation protocols. The search and recovery process primarily focused on skulls, groups of bones that remained in clothing, and any bones that were still connected to each other. In total, 86 skulls, 137 groups of bones that had at least 2 bones connected, and a couple of hundred small bones that could not be appointed to individuals, were retrieved. The material was taken to the Šejkovaca Identification Centre where the team took over 1,300 DNA samples for analysis and are now awaiting the results.

Aim To compare intraoperative hemodynamic and respiratory stability and postoperative emergence delirium between two anaesthesia regimens in children (caudal block with intravenous continuous analgosedation versus general endotracheal anaesthesia) and intensity of postoperative pain and quality of postoperative analgesia. Method Forty children aged 2-6 years who underwent lower abdominal surgery were randomized depending on performed anaesthesia into two groups: caudal block with analgosedation (group CB) and general endotracheal anaesthesia (group GA). Intraoperative hemodynamic and respiratory stability were evaluated measuring systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial blood pressure (MAP), heart rate (HR) and arterial oxygen saturation (SaO2) in preinduction (t0), at the moment of surgical incision (t1), 10 minutes after surgical incision (t2) and at the time of skin suturing (t3). Postoperative emergence delirium was evaluated using Paediatric Anaesthesia Emergence Delirium score (PAED). Postoperative pain was evaluated by Children's and Infants' Postoperative Pain score (CHIPPS). Both scores were recorded every 5 minutes during first half hour postoperatively, additionally after 60 minutes postoperatively for CHIPPS score. Results SBP, DBP and MAP were lower at t1 (p<0.0001), t2 (p<0.05) and t3 (p<0.001) in the group CB. HR was lower at all studied time points (p<0.005) in the group CB. SaO2 was lower in the CB group but comparable with the GA group. PAED and CHIPPS scores were lower at 5, 10, 15, 20 and 25 minutes postoperatively (p<0.001) in the CB group. Conclusion Caudal block with analgosedation provides better control of intraoperative hemodynamic conditions, postoperative emergence delirium and postoperative pain than general endotracheal anaesthesia.

Background: Some of main raisons for the elderly graft occlusion after successful aortal-iliac, aortal Femoral and Femoral Distal Vein Bypass, progression of main disease, continuing bad life Habits and uncontrolled risk factors such are mostly: poor nutrition traditional or fast food, Smocking and Lacks of Walking and Physical Activity Habits. Objective: The primary objective of the study was to estimate influence of Interval Walking Training Program combine with Tribulus Terrestris, 3-5 gram of Taurine and high dose of 1800mg supplementation of ALA on primary potency and vascular treatment. Secondary goals of this study is determinate by establishing better understanding connection between ordinary vascular walking therapy 30-45 min and interval walking program combine with Tribulus Terrestris, Taurine and high dose of and ALA as secondary supplementation after surgical and endovascular treatment. Methodology: The study included 112 patients, at the Clinic of cardiovascular surgery, Clinical Center University of Sarajevo, age between 50 and 75 (50 patients surgical treated with aortic-iliac, aortic-femoral and femoral distal vein bypass with and without Linton-patch/Taylor patch-first group) and (62 endovascular Iliac treated patients (indication TASC II A and B) with and without support Tribulus Terrestris, high dose of ALA and Taurine - second group). Results: Final analysis has reveal the rehabilitation outcome in 83% patients with bypass above the knee was fully rehabilitated compared to 46,6% patients with bypass below the knee was statistically considered significant by using p value less than (p<0,05) In anamnestic history in 83% patient with amputation above the knee was documented the presence of hypertension, hyperlipidemia, nicotinismus and diabetes compared to 66,7% of patients with amputation level below the knee but there was no statistically significant difference (p>0,05). Conclusion: Interval Walking Training Program on Tribulus Terrestris, Taurine and high dose of ALA had a significantly and successfully higher bypass potency and rehabilitation prognosis compare to patients without supplementation and postsurgical physical therapy concept. It is obviously the is certain link between physical activity, life style modification and serum testosterone on primary bypass potency.

Difference between industrial designer and product designer is not precisely defined. There is a lot of discussions and misunderstandings about these two professions. What is the job of industrial designer and what is the job of product designer? This question if often asked from people, which want to hire someone to design a new product for them. Through this research, same real-life design contest is given to group of students from Faculty of Mechanical Engineering, Department of Mechanical Design, at Industrial design course and to group of students from Academy of Fine Arts, Department of Product Design as product design project. Goal of the contest was to design an upholstered chair for indoor use with a modern and refined style. Goal of this research was to find some unique characteristic of designs from industrial designers and product designers. Resulted designs were evaluated analysing the fulfilment of the requirements criteria defined by contest and analysing additional criteria, which is important for new product design. Analysing the resulted designs some important conclusions are made. Most important conclusion is that industrial designer can be product designer but product designer cannot be industrial designer. For product design, engineering knowledge is not necessary, but for industrial design, it is most important.

The periodicity of Vostok ice core climate temperature and gas concentration data  indicate inherent long term past regularity of Earth’s climate, with a period of around 100,000 years, warming around 15,000 and cooling of around 85,000 years. At this point we are at the top of one of the warming periods. Vostok data cover around 430,000 years, ie 4 climate cycles (warming-cooling), of similar but not quite the same duration. In this paper we perform a detailed time and frequency analysis of these data for each of the cycles as well as their various combinations, including a full tested period of 430,000 years. Time correlation analysis allows for more accurate time lag estimate in each cycle already noted between temperature change and carbon dioxide content. We estimate these lags to lie between 1000-2500 years, longer than previously concluded. On the frequency side we perform Fast Fourier Analysis and identify full spectrum of harmonics for various cycles, and then perform energy analysis to identify which of the harmonics contributes the most. The idea is to reduce the computational load for further modeling and analysis using Kalman Filter based prediction method.  Once the prediction model is defined (a follow up paper) data will be split into two segments, Learning and Testing, in preparation of a Machine Learning fine tunning methodology. We can use last three or last two or even just last cycle to learn on, and then the current on going cycle to test on. This will result in real time prediction of relevant climate data. Assuming causal time regularity, more of these cycles are employed in training, more the prediction error for the next cycle should be reduced. Hence it is critical to perform very detailed time and frequency analysis of Vostok data as a solid data base for the prediction model to follow. 

A  hypothesis that the increasing application of both surface and ground water for irrigation of crops is a significant source of anthropogenic global warming is tested. In climate models, water is already assigned a major secondary amplifying role in warming, solely as a positive feedback from an atmosphere previously warmed by other GHGs. However, this conclusion ignores the direct anthropogenic forcing from increasing use of water in dry regions to grow crops for the human population. The area irrigated worldwide increased by around 1.5% annually between 1960 and 2000, almost trebling in magnitude.  Importantly, though only a small proportion of the Earth’s surface, this additional water vapour is dynamically focussed on dry land, intensifying its potential to elevate the troposphere and reduce the regional OLR. Our modelling analysis suggests that the increase in atmospheric water vapour from irrigation could be significantly more than 1% by 2050 compared to 1950, imposing a global forcing exceeding 1.0 W/m2.  Fortunately, this hypothesis can be tested, for example, using the satellite data on OLR acquired since the 1970s, relating this to local trends of increasing irrigation or major floods in arid regions. If found consistent with the data, current proposals to mitigate climate change by limiting combustion of fossil fuels may prove less effective. This prediction regarding the warming effect of increasing irrigation is tested using NCAR reanalysis data made possible by the natural experiments of the periodic flooding of Lake Eyre in Australia's semi-arid interior. It is recommended that this hypothesis be tested using data from local studies in irrigated regions such as changes in outgoing longwave radiation and in increased absorption of incoming shortwave radiation in air.
