The subject of the research is the analysis of services that should be offered by public administration toward legal entities and natural persons. We will suggest that it uses real-time intelligent IT systems based on data storage based on the data warehouse. Our opinion is that such systems implemented in the public administration of Bosnia and Herzegovina could offer an appropriate service to each user at a time when they need the service in a form that suits them, on the spot where he is in the moment of delivery and in the quantity that he needs. In order for a public administration to be able to offer an appropriate service, it must know its users much better and know which service they need at what time. In this paper, we analyze self-service as well as the necessary activities for all that. These are all activities that should be carried out in the future, and this work could contribute to the implementation of these processes.

Strategies to mitigate urban heat islands are a recent issue in the Austrian capital, Vienna. In this study, the uhiSolver-v2106-0.21 software was used to evaluate the summer cooling effects and humidity production of small-scale facade greening and a green pergola located in two schools within the city. Based on on-site measurement data, the study revealed that small-scale greening measures are not able to substantially reduce ambient air temperature. On a hot summer day, at 3 p.m. local time (CEST), the maximum decrease amounted to 0.3 °C at 0.1 m from the facade greening as well as inside the green pergola. As for the apparent (perceived) temperature, a reduction of up to 4 °C was observed under the green pergola compared to the unshaded roof terrace. Hence, the simulation results show that, within urban areas, a significant improvement of thermal comfort in summer can only be achieved through large-scale greenery that provides shade for pedestrians.

New online forms of giving have appeared next to more traditional ways like door-to-door collections. One of these new forms is philanthropic crowdfunding: donation- and reward-based crowdfunding. Crowdfunding is a promising method for mobilising and recruiting donors who may be unreachable via traditional methods. We analysed online giving via crowdfunding, focusing on donor characteristics and giving behaviour before and during the COVID-19 pandemic. Our analysis comprises survey research (n = 2125) observing giving behaviour on an individual level for both donors and non-donors. Our contributions are twofold. First, we report on the characteristics of donors who give to crowdfunding sources and in relation to donors who give via a door-to-door (i.e., ‘traditional’) collection focusing on micro- rather than macro-level data. Second, we compare the giving behaviour via crowdfunding with references to door-to-door collections before and during the COVID-19 pandemic. We show that the percentage of individuals supporting crowdfunding did not increase between 2018 (11%) and 2020 (12%). Regarding the amount, donors donated 13% higher amounts in 2020, but the difference was not significant. Regarding the characteristics of donors, we find that social media has a substantive role in giving via crowdfunding irrespective of other personal markers such as age, education, income, and gender, while this is not relevant in the case of door-to-door collection. Moreover, most people give to crowdfunding projects that are connected to an acquaintance, which signals that familiarity with the person initiating the crowdfunding projects plays a role. We conclude that crowdfunding, relative to more traditional giving, focuses more on informal giving than formal giving. Such an understanding requires different strategies and stimuli to increase giving via crowdfunding. © 2022 The Authors. Journal of Philanthropy and Marketing published by John Wiley & Sons Ltd.

Objective Intracerebral hemorrhage (ICH) volume is a strong predictor of outcome in patients presenting with acute hemorrhagic stroke. It is necessary to segment the hematoma for ICH volume estimation and for computerized extraction of features, such as spot sign, texture parameters, or extravasated iodine content at dual-energy computed tomography. Manual and semiautomatic segmentation methods to delineate the hematoma are tedious, user dependent, and require trained personnel. This article presents a convolutional neural network to automatically delineate ICH from noncontrast computed tomography scans of the head. Methods A model combining a U-Net architecture with a masked loss function was trained on standard noncontrast computed tomography images that were down sampled to 256 × 256 size. Data augmentation was applied to prevent overfitting, and the loss score was calculated using the soft Dice loss function. The Dice coefficient and the Hausdorff distance were computed to quantitatively evaluate the segmentation performance of the model, together with the sensitivity and specificity to determine the ICH detection accuracy. Results The results demonstrate a median Dice coefficient of 75.9% and Hausdorff distance of 2.65 pixels in segmentation performance, with a detection sensitivity of 77.0% and specificity of 96.2%. Conclusions The proposed masked loss U-Net is accurate in the automatic segmentation of ICH. Future research should focus on increasing the detection sensitivity of the model and comparing its performance with other model architectures.

: The samples of Clinopodium nepeta (L.) Kuntze (Lamiaceae) aerial parts were collected from four different localities in sub-Mediterranean area of Bosnia and Herzegovina and subjected to phytochemical profiling. Shade-dried and fresh samples were used to determine their headspace volatile organic composition by solid-phase microextraction on two differently coated fibers. Corresponding essential oils were obtained by hydrodistillation. Both headspace and essential oil were analysed by gas chromatography-mass spectrometry Among detected compounds, piperitenone oxide and pulegone were dominant in the headspace of shade-dried and fresh C. nepeta samples. The essential oils contained 42 compounds including pulegone (44.8%), piperitenone (48.8%) and piperitenone oxide (60.2%) as the major compounds, followed by limonene, cis piperitone oxide, p -menthone and dihydrocarvyl acetate. In this work, a wide range of volatile compounds present in C. nepeta samples from Bosnia and Herzegovina was determined. The obtained data provides detail phytochemical analysis of the volatiles of C. nepeta and therefore completes earlier researches of this plant from the other geographical areas.

The method of power transformer neutral point grounding is very important for power distribution network operation because it strongly affect the shapes and values of overvoltages and fault currents. Many methods of grounding are used in medium voltage (MV) power distribution networks. The selection of grounding method largely depends on the characteristics of power network connected to the substation. It is also necessary to consider the advantages and disadvantages of various neutral grounding methods during selection process to find the best solution from a technical and economical point of view. The effects of grounding methods on the characteristics of single-phase short circuit fault are discussed in this paper on the example of 110/20 kV substation ′′Bugojno′′. Modeling and simulation of the considered substation, power transmission and distribution lines are implemented in EMTP-RV software.

Razumijevanje odnosa svjesnih i nesvjesnih procesa koji se odvijaju unutar čovjekovog uma pomoću kojih se izraţavaju određena pozitivna ili negativna ponašanja, implicitna ili eksplicitna - predstavlja područje istraţivanja mnogih nauka. Buđenjem svijesti posebno u posljednjih petnaest godina akcenat se stavlja na uzroke ponašanja koja diskriminiraju po bilo kojoj osnovi i ukazuju na potrebu razvijanja boljih socijalnih odnosa na temelju ravnopravnosti, tolerancije, čovjekoljublja i isti su intencijom brojnih školskih programa.Škola i druge institucije koncipirane su tako da predstavljaju resurs društvu, pa čak i onda kada isto modeluje neprihvatljive oblike ponašanja budućim generacijama. Odgojno-obrazovni sistem djeluje interventnim i preventivnim programima radi preveniranja ovih oblika ponašanja dok djeca istodobno usvajaju raznovrsne predrasudne i stereotipne modele ponašanja, izgraĎujući stavove o drugima, čak i onda kada “te druge” nikada nisu sreli. Implicira da kompetitivna sredina, nedostatak saradnje, pasivnost i sankcionisanje kritičkog mišljenja predstavlja pogodno tlo za diskriminaciju svih kategorija društva te da načinom rada heterogene skupine nastavnog osoblja, ni škola nije imuna na nedostatak kvalitete. U radu se upravo bavimo procjenom jačine djelovanja kvalitete rada nastavnika i stručnih saradnika i to onih, fokusiranih na prevenciju neprihvatljivih obrazaca ponašanja kroz minimum tj. samo sedam radionica stručnih saradnika i nastavnika. Pred test i post test obuhvataju 246 učenika različitih uzrasta iz osnovnih i srednjih škola i 147 radionica od strane 21 nastavnika/stručnog saradnika. Rezultati govore u prilog potreba za intervencijama u slučajevima pojave nasilja u školama, te o promjenama ponašanja učenika prilikom rješavanja problema u situacijama prije i poslije učestvovanja u radionicama Programa. Više od 50% odgovora nastavnika i saradnika govore u prilog pozitivnih efekata nakon primjene sedam radionica. Rad je empirijskog karaktera zasnovan na imenovanju pojava koje ugroţavaju kvalitet (su)ţivota, a koje djeca internalizuju u budućim ponašanjima, te nudi smjernice za uspostavljanje prakse bazirane na obrazovanju koje poziva na mir u svim aspektima života trenutnih i budućih generacija.

On a sample of 147 students (78 male and 69 female), in the first year of the Faculty of Security Studies from Banja Luka, research was conducted with the aim of determining the differences between the achieved grade and the selfassessment of motor skills between male and female students, based on the results obtained by applying adequate tests for assessment and self-assessment of students motor status. Assessment of the motor abilities was performed through a battery of six tests: the maximum number of push-ups performed in 10 seconds (MSKL) - used to assess the dynamic strength of the arms and shoulder girdle, the standing long jump (MSDM) - used to assess the explosive power of the lower extremities, agility with with a club (MOKP) - used to assess the coordination of the whole body, the maximum number of trunk lifts performed in 30 seconds (MPTR) - used to assess the dynamic strength of the trunk, hand tapping (MTAR) - used to assess the frequency of arm movements, forwardroll – back roll - running (MKNT) – used to assess the motor ability of agility. For the self-assessment of motor skills, a constructed questionnaire with six answers was used: excellent (5), above average (4), average (3), below average (2), bad (1) and very bad (0). The respondents showed a good self-assessment of motor skills, where a statistically significant difference between male and female students was recorded only in the variable for self-assessment of dynamic arm and shoulder girdle strength. Male students showed better self-assessment in the variables for assessing dynamic arm and shoulder girdle strength, dynamic trunk strength, body coordination and hand movement frequency, while female students showed better self-assessment in variables for assessing explosive leg strength and agility. The authors recommendation is that the method of self-assessment of motor skills be implemented in the teaching process, when teaching the subject Special Physical Education 1, in order to improve awareness of the role and importance of the anthropological status of students and to encourage them to exercise regularly.
