Introduction: Psoriasis is a chronic disease. Research shows the emergence of harmful habits such as cigarette smoking and alcohol consumption in people with psoriasis. Aim: The aim of this study was to determine the frequency of habits, cigarette smoking and alcohol consumption in patients with psoriasis, sexual distribution, and the relationship of habits with the severity of the disease. Methods: The prospective study included 129 subjects with psoriasis, of which 67 or 51,94% were women and 62 or 48,06% were men. Results: The frequency of cigarette smoking was 41,09%, alcohol consumption 24,80%. The gender distribution of cigarette smoking was: 35,82% of women and 46,77% of men smoked cigarettes. The gender distribution of alcohol consumption is: women 5,97% and men 45,16%. The severity of psoriasis, that is PASI score and cigarette smoking were statistically significantly related (r=0,63), and PASI score and alcohol consumption were not statistically significantly related (r=0,32). Conclusion: Cigarette smoking and alcohol consumption are present in psoriasis sufferers, cigarette smoking is associated with disease severity, and alcohol consumption is not. It takes knowledge of the habits of people with psoriasis and a multidisciplinary approach to get rid of harmful habits.

The Internet of Things (IoT) is a leading trend with numerous opportunities accompanied by advantages as well as disadvantages. Parallel with IoT development, significant privacy and personal data protection challenges are also growing. In this regard, the General Data Protection Regulation (GDPR) is often considered the world’s strongest set of data protection rules and has proven to be a catalyst for many countries around the world. The concepts and interaction of the data controller, the joint controllers, and the data processor play a key role in the implementation of the GDPR. Therefore, clarifying the blurred IoT actors’ relationships to determine corresponding responsibilities is necessary. Given the IoT transformation reflected in shifting computing power from cloud to the edge, in this research we have considered how these computing paradigms are affecting IoT actors. In this regard, we have introduced identification of IoT actors according to a new five-computing layer IoT model based on the cloud, fog, edge, mist, and dew computing. Our conclusion is that identifying IoT actors in the light of the corresponding IoT data manager roles could be useful in determining the responsibilities of IoT actors for their compliance with data protection and privacy rules.

Future denser air-ground vehicle networks (AGVNs) face challenges such as resource allocation, mobility management, secure transmission, and so on. At the same time, surveillance is a must for modern air traffic management. This motivates us to find opportunities in the aerial vertical by forming a conceptual surveillance plane for aerial vehicles. In this article, we propose an enhanced software-defined network architecture where the surveillance plane can provide local and global surveillance information to macro stations, acting as a side system for the communication links. We review air- ground communications and, by summarizing challenges and opportunities, propose the enhanced architecture of side-information-assisted networks in detail. We then present how we obtain, organize, manage, and utilize the local and global side information by a so-called aviation data lake (ADL). The data lake can be easily connected with advanced machine learning schemes and, thus, provide timely, context-aware metrics and predictions.

Pyrrhalta viburni (Coleoptera: Chrysomelidae), is a chrysomelid native to Eurasia. It gained importance as an invasive species in North America due to its ability to cause serious damage to native and ornamental Viburnum spp. plants. In our study Pyrrhalta viburni was recorded as a new record in the fauna of Bosnia and Herzegovina. It has been recorded on four locations in Bosnia and Herzegovina in the region of Sarajevo. As it is feeding on Viburnum spp. that are commonly used as ornamental plants, its monitoring in urban and other habitats is suggested.

A company that handles natural resources such as forests is a complex economic entity. In addition to economic performance at annual level, the biological component of sustainable forest management should also be considered. It is therefore extremely important to achieve efficient business performance. Financial analysis is a process of determining important business and financial characteristics of a company from accounting data. It is characterized by a wide use of financial reports and various financial indicators key figures. The paper presents business indicators of the main state-owned forest companies in selected countries of South East Europe (Croatia, Slovenia, Serbia, Bosnia and Herzegovina, and North Macedonia) using the method of comparative analysis based on financial reports (such as balance sheet and income statement). In countries where there are more than one state-owned forest companies, they were selected according to their importance for forest management and business results (share of forests, number of employees, profit and annual felling). The research results show the revenue and expenditure of the selected companies and profitability indicators such as return on equity (ROE) and return on assets (ROA). According to the annual business reports for 2017 and 2018, the company Croatian Forests Ltd. has the highest number of employees (7787 in 2018). The highest ratio ROA (32.17) and ROE (39.82) were achieved in the Slovenian state forestry company in 2017, which was founded in 2016. For 2018, the best results are achieved in the Slovenian Forest Company (SiDG), while the weakest results are achieved in the State Forest Company in North Macedonia. The profit per employee decreased in 2018 for most companies, but most significantly in North Macedonia, where it was four times lower. On the basis of the comparative analysis presented, all companies have a positive cost-benefit ratio, but longterm planning of forest management should follow biological and economic regulations to be competitive on the free market.

Cilj istraživanja je usporediti rast provenijencija obične bukve, te utvrditi početak i završetak fenoloških faza listanja provenijencija obične bukve u međunarodnom testu provenijencija u Bosni i Hercegovini. Test obuhvaća osam provenijencija iz Bosne i Hercegovine, četiri iz Njemačke, tri iz Srbije, po dvije iz Hrvatske, Rumunije i Švicarske te jednu iz Mađarske (tablica 1). U proljeće 2017. godine mjerili smo visine i promjere vrata korijena biljaka u međunarodnom testu provenijencija. Također smo promatrali i bilježili pojavu fenoloških faza listanja kroz šest faza (slika 1): A – Spavajući pup; B – Pupovi izduženi, nabubreni, žućkasto-zelenkaste boje; C – Pupovi se počinju otvarati i vidi se prvo zelenilo; D – Počinju se javljati savijeni dlakavi listići; E – Listovi su odmotani, još lepezasti, prisutne blijede liske; F – Listovi su potpuno ­razvijeni, glatki i široki. Prosječna visina za sve provenijencije bila je 164,6 cm (tablica 2), a prosječan promjer vrata korjena 33,4 mm (tablica 5). Najmanju prosječnu visinu (104,2 cm) i promjer (22,6 mm) imala je provenijencija Alba - Iulia iz Rumunije (9664). Najveću prosječnu visinu (197,4 cm) i promjer (40,1 mm) imala je provenijencija Dilj Čaglinski iz Hrvatske (9624). Utvrdili smo razlike između provenijencija u pogledu pojavljivanja fenoloških faza listanja (tablica 8), kao i dužini trajanja faza (tablica 10). Faza B se najranije pojavila 31.3. kod provenijencija Grmeč Jasenica i Dinara iz Bosne i Hercegovine i Cer iz Srbije. Najkasnije se pojavila 8.5. kod provenijencija Herzogenbuchsee iz Švicarske i NS Hasbruch iz Njemačke. Fenofaza F najranije se pojavila 1.5. kod provenijencije Valkonya iz Mađarske. Analiza varijanse pokazala je da postoje statistički značajne razlike između provenijencija, kako u visini (tablica 3) i promjeru vrata korijena (tablica 6) tako i u dužini trajanja fenoloških faza (tablica 10). Biljke u međunarodnom testu provenijencija obične bukve su za vrijeme mjerenja bile stare 12 i 13 godina. Potrebno je vršiti daljnja mjerenja morfoloških svojstava kako bi se utvrdile tendencije rasta pojedinih provenijencija u idućim fazama razvoja. Također je potrebno promatrati fenološke faze kako bi se procijenili utjecaji genetske konstitucije i godišnje klime na fenološka kretanja. Rezultati ovog istraživanja poslužit će za odabir najboljih provenijencija po produktivnosti i otpornosti na kasne proljetne mrazeve.

Background and Objective: Although smoking and the physical activity level (PAL) are important determinants of health status in adolescence, there is a lack of information on the relationship between smoking and PAL in early adolescence. The objective of this study was to evaluate the gender-specific relationship between smoking and PAL in 14-to-16-year-old adolescents. Materials and Methods: The sample included 650 adolescents (337 girls, 14.7 ± 0.5 years at first testing wave) from Bosnia and Herzegovina. During the first testing wave, participants were tested using structured questionnaires. Second testing was commenced after approximately 20 months (16.4 ± 0.6 years). The variables were age, gender, socioeconomic status, living environment, cigarette smoking (predictors), and PAL (criterion). Predictors were measured at the first wave, and criterion at the first-wave and second-wave. Results: For girls, smoking was negatively correlated to PAL at the first-wave (OR: 0.75, 95% CI: 0.55–0.95) and at the second-wave (OR: 0.73, 95% CI: 0.71–0.96). No significant association between smoking and PAL was found for boys. Results suggest that adolescent boys and girls do not follow the equal trajectories when it comes to relationships between smoking and PAL. Conclusions: In developing promotional public health actions related to a decrease of smoking and increase of PAL, a gender-specific approach is highly recommended. Further studies analyzing the cause–effect relationship between consumption of other types of psychoactive substances and PAL in this age group are warranted.

The possibility for utilization of waste heat from processes in the food industry is presented in this paper. The need for reuse of waste heat comes from the fact that energy consumption in industrial companies is uneconomical and that environmental pollution has increased. Therefore, one of the method of reuse of waste heat that is applicable in industrial processes is presented in the paper. Potential primary energy savings is presented by implementing the waste heat recovery in the food factory. The paper presents a simplified solution proposal for installation of heat exchangers with the aim of utilizing the waste heat of the refrigerant. The results showed that by the implementation of simple heat recovery significant annual fuel energy savings can be achieved as well as fuel cost savings.

Background Patients with head and neck squamous cell carcinoma (HNSCC) can develop lung squamous cell carcinoma (LuSCC), which could be the second primary tumor or HNSCC metastasis. Morphologically it is difficult to distinguish metastatic HNSCC from a second primary tumor which presents a significant diagnostic challenge. Differentiation of those two malignancies is important because the recommended treatments for metastatic HNSCC and primary LuSCC differ significantly. We investigated if the quantification of the promotor methylation status in HNSCC and LuSCC differs. Methods Primary HNSCC ( N  = 36) and LuSCC ( N  = 17) were included in this study. Methylation status in the ASC/TMS1/PYCARD (apoptosis-associated speck-like protein containing a caspase recruitment domain; 8 CpG sites) and MyD88 (Myeloid differentiation primary response protein 88; 10 CpG sites) promoters was analyzed. Bisulfite converted DNA, isolated from tumor tissue was quantified using pyrosequencing. Results of pyrosequencing analysis were expressed as a percentage for each tested CpG site. Receiver-operating characteristic (ROC) curve analysis was used for the evaluation of the diagnostic properties of selected biomarkers. Results CpG sites located in the promoters of ASC/TMS1/PYCARD_CpG8 (− 65 upstream) and MyD88_CpG4 (− 278 upstream) are significantly hypermethylated in the HNSCC when compared with LuSCC ( p  ≤ 0.0001). By performing ROC curve analysis we showed that corresponding areas under the curve (AUC) were 85–95%, indicating that selected CpG sites are useful for a distinction between primary LuSCC and primary HNSCC. Conclusions Results of the present study indicate that there is a significant difference in the methylation status of tested genes between primary HNSCC and LuSCC. However, to prove this approach as a useful tool for distinguishing second primary LuSCC from HNSCC metastasis, it would be necessary to include a larger number of samples, and most importantly, metastatic samples.

In the modern world of rapidly changing technologies, fiscal policy engagement is also needed to promote and adapt to these changes. In order to achieve economic growth, every country needs to ensure an adequate institutional environment and financial incentives for technological development. These investment incentives operate through tax system directly or indirectly. The aim of the paper is to assess the impact of Slovenia's endogenous economic growth factors on exports in the 2009–2016 period. A panel data analysis was applied to obtain empirical results. The analysis showed that a 1% real increase in government subsidies to the economy over three subsequent years increases real investment in research and development by 0.45%, and after a two-year period yields a 0.27% increase in employment of persons with higher education. The latter has a 0.14 % positive impact on the growth of exports after another three-year term. In addition to endogenous factors of economic growth in the Slovenian case, exports are also affected by the dynamics of real world trade, by the dynamics of exchange rates corrected for relative prices, and by the dynamics of wage rates.
