KOMPONENTENETO OBRTNOG KAPITALA I PROFITABILNOST PODUZEĆA U HRVATSKOJ NA TEMELJU PANEL PODATAKA OD 2016. DO 2023.
No full textThis study examines the relationship between individual components of net working capital and corporate profitability in Croatia over the period from 2016 to 2023. The analysis focuses on two key profitability indicators, ROA and ROE, while the core working capital components included in the research comprise inventory, cash, receivables, and short-term liabilities. To account for the crisis period, a COVID_dummy variable was introduced to capture the direct pandemic impact years. Three methodological approaches were employed in the empirical analysis: classical OLS regression on transformed data, fixed effects panel regression, and dynamic GMM regression to address potential endogeneity and time dependence. The results indicate that receivables and cash have a positive influence on profitability, whereas short-term liabilities exhibit a negative effect. The impact of the COVID_dummy variable was not statistically significant. The findings confirm the importance of disaggregated analysis of working capital components in assessing firms’ financial performance and highlight the need to include additional control variables in future research.Ovo istraživanje ispituje odnos između pojedinačnih komponenti neto obrtnog kapitala i profitabilnosti poduzeća u Hrvatskoj u razdoblju od 2016. do 2023. godine. Analiza je usmjerena na dva ključna pokazatelja profitabilnosti, ROA i ROE, dok su ključne komponente obrtnog kapitala uključene u istraživanje obuhvaćaju zalihe, gotovinu, potraživanja i kratkoročne obveze. Kako bi se uzelo u obzir krizno razdoblje, uvedena je lažna varijabla COVID_dummy kako bi se obuhvatile godine izravnog utjecaja pandemije. U empirijskoj analizi korištena su tri metodološka pristupa: klasična OLS regresija na transformiranim podacima, panel regresija s fiksnim učincima i dinamička GMM regresija za rješavanje potencijalne endogenosti i vremenske ovisnosti. Rezultati upućuju na to da potraživanja i gotovina pozitivno utječu na profitabilnost, dok kratkoročne obveze imaju negativan učinak. Utjecaj varijable COVID_dummy nije se pokazao statistički značajnim. Nalazi potvrđuju važnost dezagregirane analize komponenti obrtnog kapitala u procjeni financijske uspješnosti poduzeća i naglašavaju potrebu uključivanja dodatnih kontrolnih varijabli u buduća istraživanja
Prediction of mechanical properties of zinc alloy based on machine learning algorithm
No full textAs a medical implant material, zinc alloys need to have high strength and suffi-cient hardness to support bone regeneration. Therefore, it is important to clearly define the design criteria for zinc alloys that meet the mechanical property re-quirements of degradable medical implants. In this work, mechanical property data of Zn-Mg-Mn alloys were obtained through experimental research and liter-ature collection. A performance-oriented machine learning (ML) model was used to predict the compressive yield strength and hardness of Zn-Mg-Mn alloys with different element types, contents and alloy preparation processes, and then the in-fluence of element types and contents on the microstructure and macroscopic me-chanical properties of the material was explored. Based on the existing dataset, the model compared six different ML algorithms and identified the optimal prediction algorithm. To further verify the accuracy of the model’s predictions, data outside the dataset were randomly selected for comparative analysis with the model re-sults. The results showed that the prediction errors of the algorithm designed in this work for compressive yield strength and hardness were less than 2 % and 2.4 %, respectively
DRUŠTVENE PREDRASUDE I NJIHOV UTJECAJ NA OGRANIČAVANJE PROFESIONALNOG RAZVOJA ŽENA – EMPIRIJSKI PRISTUP
No full textThe considerations contained in this article relate to the broad issue of discrimination against women in the labour market. In this respect, the aim of the study is to verify the areas in which women feel discriminated against in the labour market and which impact on the inhibition of their professional development. In the first part, a review of the literature is carried out, where the terms stereotype, prejudice and discrimination are defined. In this respect, the types of discrimination occurring in the labour market are also indicated. The empirical part presents the results of own research. Following on from the above, a preliminary survey was conducted with 310 respondents from Poland at the beginning of 2024. It concerned an assessment of society's views on the role of women in various dimensions of the socio-economic environment. Based on the respondents' answers, a verification of the employment areas in which women feel discriminated against was carried out. Furthermore, using the econometric package GRETL, an Ordinary Least Squares method (OLS) was used to assess the relationship between these areas. The final section presents detailed conclusions and identifies limitations and recommendations for further research.Razmatranja sadržana u ovom članku odnose se na široko pitanje diskriminacije žena na tržištu rada.

Acute Prostatitis
No full textAkutni prostatitis je bakterijska infekcija prostate koja zahtijeva adekvatnu empirijsku antimikrobnu terapiju. Klinički se manifestira naglim početkom općih simptoma poput visoke temperature i malaksalosti, uz izražene simptome donjeg urotrakta. Dijagnoza se postavlja na temelju kliničke slike i digitorektalnog pregleda. Liječenje se provodi dugotrajnom antibiotskom terapijom, najčešće fluorokinolonima, u trajanju od 4 do 6 tjedana kako bi se spriječio recidiv i razvoj kronične infekcije. Kod težih slučajeva indicirana je hospitalizacija s parenteralnom primjenom antibiotika. Potencijalne ozbiljne komplikacije su sepsa i apsces prostate, a dugoročno razvoj kroničnog prostatitisa. Akutni prostatitis značajno narušava seksualnu funkciju i kvalitetu života. U mlađih bolesnika dijagnostika i liječenje trebaju uključiti i prepoznavanje spolno prenosivih uzročnika.Acute prostatitis is a bacterial infection of the prostate that requires adequate empirical antimicrobial therapy. Clinically, it presents with a sudden onset of general symptoms such as high fever and fatigue, accompanied by pronounced lower urinary tract symptoms. The diagnosis is based on the clinical presentation and a digital rectal examination. Treatment involves prolonged antibiotic therapy, most commonly with fluoroquinolones, lasting 4 to 6 weeks to prevent recurrence and the development of chronic infection. In more severe cases, hospitalization with parenteral administration of antibiotics is indicated. Potential serious complications include sepsis and prostatic abscess, and in the long term, the development of chronic prostatitis. Acute prostatitis may also impair sexual function and quality of life, while sexually transmitted pathogens should be considered, especially in younger men
ALBUM NOVEL: FORCING REMEMBRANCE
No full textSummary:
This paper examines the way memory/remembrance works in some various (social and private) moments (a war and post-war period, crisis, need for self-determination) and analyses a dialectic relation between the culture of remembrance and the culture of oblivion. Inside the wider context of post-modernistic accords and due to the depression caused by the local war atmosphere, there appeared some new narrative forms which try to define the problems of the actual moment (mostly national and individual identity at the end of the 20th and the first years of the 21st century: Ž. Čorak, D. Ugrešić, J. Horvat, M. Kirin ) and we propose its genre-related form to be album novel. The justification for distinguishing this form and engaging with it is evidenced by the emergence of new works, among which we single out recent novels (20s of the 21st centuary) written in the Kajkavian idiom (P. Sabolek, T. Ribić). The discoursive space of this form encompasses, on the one hand, the discourse of hope based on the authority of tradition and on the other hand the discourse of scepticism, as it was adopted by the critics of postmodernism (Lyotard, Derrida)
Application of hydrogen peroxide in the protection of grapevine (Vitis vinifera L.) against grapevine, trunk diseases
No full textBolesti drva vinove loze ubrajaju se među glavne čimbenike koji smanjuju produktivnost vinograda, uzrokujući progresivno propadanje trsa i gubitak prinosa. Dosadašnja istraživanja naglašavaju potrebu za učinkovitijim alternativnim metodama zaštite zbog ograničenja konvencionalnih kemijskih tretmana. Vodikov peroksid (H₂O₂) prepoznat je kao potencijalni tretman zbog svojih antimikrobnih svojstava no, istraživanja o njegovoj primjeni u zaštiti vinove loze još su ograničena. Cilj ovog istraživanja bio je procijeniti učinkovitost primjene vodikovog peroksida na simptomatičnim trsovima u smanjenju simptoma bolesti drva te njegov utjecaj na prinos i kvalitativne parametre mošta. Pokus je proveden tijekom vegetacijske sezone 2021. na sortama vinove loze 'Malvazija istarska' i 'Cabernet Sauvignon'. Vodikov peroksid (10 %) u količini od 5 ml injektiran je u trsove, a učinkovitost tretmana procijenjena je na temelju vizualne ocjene zdravstvenog stanja trsa, kao i analiza prinosa, sadržaja šećera, pH vrijednosti i ukupne kiselosti mošta. Rezultati pokazuju da primjena vodikovog peroksida smanjuje simptome bolesti drva i potiče oporavak trsa, osobito kada se primjenjuje u ranim fazama bolesti. Dok je tretman značajno poboljšao prinos kod oporavljenih trsova 'Malvazije istarske', nisu uočene značajne negativne promjene u sadržaju šećera, pH vrijednosti ili ukupnoj kiselosti mošta. Tretman kod Cabernet Sauvignona nije utjecao na razlike u prinosu, sadržaju šećera, pH vrijednosti niti ukupnoj kiselosti mošta. Potrebna su daljnja istraživanja radi optimizacije uvjeta tretmana i razjašnjavanja mehanizma djelovanja vodikovog peroksida u upravljanju bolestima vinove loze.Grapevine trunk diseases (GTDs) are major contributors to vineyard productivity decline, causing progressive vine deterioration and yield loss. Existing research highlights the need for effective alternative protection methods due to the limitations of conventional chemical treatments. Hydrogen peroxide (H₂O₂) has been identified as a potential treatment because of its antimicrobial properties; however, studies on its use in grapevine protection are still limited. This study aimed to evaluate the effectiveness of H₂O₂ application on symptomatic grapevines in reducing GTD symptoms and its impact on yield and qualitative must parameters. The experiment was conducted during the 2021 growing season on the grapevine cultivars Malvazija istarska and Cabernet Sauvignon. H₂O₂ (10%) at a dose 5 ml was injected into the vines, and treatment efficacy was assessed through a visual evaluation of vine health, as well as analyses of yield, sugar content, pH, and titratable acidity of grape must. Results showed that H₂O₂ application reduced GTD symptoms and promoted vine recovery, particularly when applied at early disease stages. While the treatment significantly improved yield in recovered vines of Malvazija istarska, no significant negative changes were observed in sugar content, pH, or titratable acidity of the must. The treatment has not affected differences in yield of Cabernet Sauvignon, sugar content, pH, or total acidity of the must. Further research is required to optimize treatment conditions and elucidate the mechanisms of H₂O₂ action in grapevine disease management
