1438. Effects of governmental data governance on urban fire risk : a city-wide analysis in ChinaZhao-Ge Liu, Xiang-Yang Li, Grunde Jomaas, 2022, original scientific article Abstract: The effects of data governance (as a means to maximize big data value creation in fire risk management) performance on fire risk was analyzed based on multi-source statistical data of 105 cities in China from 2016 to 2018. Specifically, data governance was first quantified with ten detailed indicators, which were then selected for explaining urban fire risk through correlation analysis. Next, the sample cities were clustered in terms of major socio-economic characteristics, and then the effects of data governance were examined by constructing multivariate regression models for each city cluster with ordinary least squares (OLS). The results showed that the constructed regression models produced good interpretation of fire risk in different types of cities, with coefficient of determination (R2) in each model exceeding 0.65. Among the indicators, the development of infrastructures (e.g. data collection devices and data analysis platforms), the level of data use, and the updating of fire risk related data were proved to produce significant effects on the reduction of fire frequency and fire consequence. Moreover, the organizational maturity of data governance was proved to be helpful in reducing fire frequency. For the cities with large population, the cross-department sharing of high-value data was found to be another important determinant of urban fire frequency. In comparison with existing statistical models which interpreted fire risk with general social factors (with the highest R2 = 0.60), these new regression models presented a better statistical performance (with the average R2 = 0.72). These findings are expected to provide decision support for the local governments of China and other jurisdictions to facilitate big data projects in improving fire risk management.

1439. Fire safety assessment of sprinkler systems for car parks using the J-value methodologyMalika Alimzhanova, Michael Spearpoint, Grunde Jomaas, 2022, original scientific article Abstract: A J-value assessment was carried out to quantify the costs and benefits of sprinkler system installation in car parks, both with respect to life safety and property protection. Nine scenarios were established based on collected input data. All car park types were considered for the USA, England, Scotland, Wales and the UK nations collectively, while separate considerations were made for multi-storey car parks (MSCPs) in the UK and for MSCPs, underground and other parking types in England.
Even when assuming 100% sprinkler effectiveness, the J-values for the nine scenarios were all larger than unity (ranging from 5 to 555), thus indicating that the installation of sprinklers is not a cost-effective investment for car parks from a societal point of view. The analysis showed that different car park types must be treated separately, due to specifics of structure and fire statistics. The lowest J-values were obtained for MSCPs and underground car parks. Sprinkler installation mainly provides property protection benefits, because of property loss savings substantially outweigh those associated with life safety.
Even though sprinklers were not cost-effective for car parks in the current analysis, the scarcity of data and new emerging technologies suggests that further investigation is needed.

1440. Kulturna in jezikovna dediščina Hijacinta Repiča, frančiškana pri sv. Ani v KopruDiana Košir, 2023, original scientific article Abstract: Prispevek prinaša pregled zapisane zapuščine frančiškana Hijacinta Repiča (1863–1918) iz koprskega samostana sv. Ane. Arhivski viri so danes hranjeni na Domoznanskem oddelku koprske knjižnice, v Pokrajinskem arhivu Koper, v provincialnih arhivih reda manjših bratov v Ljubljani in Benetkah ter v samostanu sv. Ane. Avtorica jih analizira, opiše in umesti v slovensko kulturno zgodovino v Istri na prelomu 19. stoletja. Na temelju analize primarnih in sekundarnih virov se v novi luči predstavlja plodovito delovanje p. Repiča. Njegova prizadevanja za širjenje slovenske besede kažejo, da je bil – čeprav za samostanskimi zidovi – na prelomu stoletij eden od prvih predstavnikov slovenskega slovstva v Istri.
Keywords: pater Hijacint Repič, frančiškani, samostan sv. Ane v Kopru
