The development of agriculture is closely linked to technology and innovation. Drones have become a practical tool that helps improve agricultural production. This research focuses on choosing the spraying drone with the best features for the companyAgricultural goods Semberija. A multi-criteria decision-making process based on expert opinions was used to evaluate eight different drones across ten criteria. The fuzzy SiWeC (Simple Weight Calculation) method was applied to determine theimportance of each criterion, showing that all criteria were similarly important in the decision-making process. To select the best drone, the fuzzy COmpromise Ranking from Alternative SOlutions (CORASO) method was used. The results show that theDJI Agras T30 drone has the best features and is the preferred choice for purchase. These findings were confirmed by further comparative and sensitivity analyses. This study highlights the use of new methods for selecting equipment in agriculture.

Background/Aim: Basal cell carcinoma (BCC) is the most common cancer of the skin. It is believed that increased UV radiation from the sun accounts for almost 90 % of the risk of BCC. There is a growing trend in the incidence of BCC in a younger population. The aim of study was to analyse the initial clinical symptoms of BCC that may be important for the early detection of this skin tumour. Method: The study was a prospective, multicentre study performed in the period from March 2017 to February 2022. A total of 69 respondents with BCC were analysed. Respondents applied for a targeted examination to examine a suspicious skin lesion (due to certain symptoms) or were diagnosed with BCC by accident, when examining other skin changes. Respondents were divided into 2 groups. The first, Group I (35 respondents), consisted of respondents with nodular BCC. The second, Group II (34 respondents), consisted of respondents with superficial spreading BCC. Initially, a careful history and data on the characteristics, shape and character of the tumour were taken from all respondents. Data on all (even the smallest) initial symptoms and relevant signs of evolution, as well as subjective problems related to the tumour were noted. All respondents underwent dermoscopy of suspected skin changes. Results: A significant difference was found between the examined groups in the characteristics of bleeding, crust formation and tendency to injury in lesions, where they occur more often in patients with nodular BCC. Symptoms such as burning and flaking occurred significantly more often in patients with superficial spreading BCC (p < 0.01), as well as the diameter of lesions over 5 mm (p < 0.05). Conclusion: Early clinical diagnosis of BCC is possible with a tumour diameter of only a few mm. The predominant initial (highly susceptible) symptoms of nodular BCC were initial bleeding and / or scab formation on the lesions, as well as propensity to injury. The superficial spreading form of BCC was often larger than 5 mm in diameter, with more frequent scaling of the lesion, as well as burning and stinging sensations in the tumour area. Itching was observed to be a very common previous occurrence in the BCC initial focus zone in subjects of both study groups. Dermsocopy is a highly reliable diagnostic method for early detection of BCC.

Background: Lyme borreliosis is a multisystemic infection caused by the spirochete Borrelia burgdorferi. Erythema migras is the main clinical marker of the disease. Objective: This study aimed was to investigate the frequency and clinical manifestations of European borreliosis on the skin, and to determine the significance of these findings for diagnosis and therapy. Methods: A retrospective-prospective clinical study of outpatients treated and monitored in a private clinic of an infectologist was conducted over nine years from to 2013-2021. The study was clinical, descriptive and analytical in nature. Results: In the investigated period, 509 (30.8%) patients with borreliosis symptoms were treated. EM in our patients occurred under the following conditions: a) ringed redness, b) redness of target cels and d) continuous round or oval redness of different sizes of individual redness, or multiple occurrences with primary dissemination. Skin changes with multiorgan chronic symptoms of borreliosis occurred in 67.7% of cases the including: walking redness of different shapes and sizes, pink borreliosis stretch marks, white borreliosis stretch marks, borreliosis palms and soles, psoriatic changes, Acrodermatitis chronica atrophicans, Scleroderma circumscripta-morphae, Erythema nodosum, Granuloma anulare and Lichen striatus et atrophicans. Of the 509 patients treated for borreliosis, 32.3% with multi-organ symptomatology had no skin changes. Conclusion: The skin manifestations of European borreliosis are multi-layered and Erythema migrans are basic, but not the only markers of the disease. ‘Pink borreliose stretch marks, “white borreliosis striae”, “borreliosis palms or soles”, and intermittent redness accompanied by itching are unique markers for the diagnosis of chronic borreliosis, if they are manifested.

To behave in a socially responsible manner and to support the concepts of sustainable development, organizations apply various processes and activities for greening their business. In addition to green marketing, supply and distribution chain, production, packaging and recycling, green human resources management (GHRM) also plays a big role. For this purpose, organizations incorporate a green component into all human resources management (HRM) phases, thereby building a green employer brand. This paper examines the extent to which organizations in Serbia and Bosnia and Herzegovina apply GHRM activities and practices, and whether there are differences in the application of these practices depending on the size and business sector. Empirical research carried out in Serbia and Bosnia and Herzegovina has found that green activities and HRM practices are applied to a small extent, with slightly higher results achieved by small and manufacturing organizations. The findings indicate the need for greater engagement of organizations to strengthen the awareness of the importance of GHRM, support their sustainable development and strengthen the brand in domestic and foreign markets.
