Published: October 2024

Zdravstvena zaštita u Republici Hrvatskoj organizirana je na primarnoj, sekundarnoj, tercijarnoj te razini zdravstvenih zavoda. Većina medicinskih sestara i tehničara radi na sekundarnoj i tercijarnoj razini koja uključuje kontinuiranu 24-satnu skrb te je iz tog razloga i najveći broj medicinskih sestara i tehničara izloženo utjecaju noćnog rada. Noćni rad utječe na zdravlje na način da dovodi do deprivacije sna, umora, rizika za psihičke i fizičke smetnje te bolesti, ali i poremećaje u socijalnom i obiteljskom životu. Pretražene su 3 baze podataka: Pubmed, Google scholar i Proquest; kriterij za odabir bio je sustavni pregled literature i meta analiza, a u obzir su dolazili samo članci na engleskom jeziku. Pregled literature rađen je prema PRISMA smjernicama, kvaliteta članaka ocijenjena je AMSTAR-R instrumentom za ocjenjivanje, pouzdanost između ocjenjivača napravljena je Cohenovim kappa koeficijentom, a kako bi se utvrdilo preklapanje korištene literature korištena je metoda ispravljenog pokrivenog područja (eng. Corrected Covered Area (CCA)). Pregledom sustavnih pregleda i meta analiza, rezultati prikazani u ovom radu dobiveni su iz 8 istraživanja od kojih su 3 sistematski pregled, a 5 meta analize, objavljivani između 2013. i 2021. godine iz različitih dijelova svijeta (Europa, Azija, Amerika, Australija, Afrika). Istraživanja su pokazala da noćni rad utječe na san medicinskih sestara u smislu smanjenja njegove kvalitete te na samo zdravlje u smislu povećanja rizika od povećane težine, razvoja metaboličkog sindroma, dijabetesa tipa 2, kardiovaskularnih bolesti, karcinoma dojke, bolova u leđima te povećanja unosa alkohola. Osim utjecaja na san i zdravlje medicinskih sestara, noćni rad može dovesti i do drugih rizika kako za medicinske sestre poput rizika od ubodnih incidenata, ozljeda i bolova, psihičkih i emocionalnih smetnji, željom za odlaskom te automobilskih nesreća, tako i za krajnje korisnike zdravstvene zaštite, a to su pacijenti, a odnose se na rizik od pogrešne administracije lijekova, dekubitusa, hipoglikemije, urinarne infekcije te bolničke infekcije. Potrebna su dodatna istraživanja povezana s problematikom noćnog rada kako za same rizike koje on donosi tako i za utjecaj potencijalnih rješenja na iste. Osim toga, potrebna je trajna edukacija medicinskih sestara o ovom problemu kako bi se na vrijeme prepoznale posljedice, na njih pravovremeno reagiralo te na taj način smanjile dugoročne posljedice na zdravlje. Nužno je i kontinuirano praćenje zdravstvenog stanja te poboljšanje radnih uvjeta u skladu s procjenom rizika pojedinog radilišta.
Utjecaj buke na zdravstvene djelatnike u jedinicama intenzivnog liječenja
Authors: Desić Doris , Nola Iskra Alexandra
Published: October 2024

Unatoč preporukama Svjetske zdravstvene organizacije o ograničavanju buke u bolnicama na prosječnu razinu zvuka koja ne bi trebala prelaziti 35 dB (a najviše 40 dB tijekom noći), mjerenja intenziteta buke u jedinicama intenzivnog liječenja dosežu nerijetko i dvostruko više vrijednosti. Američka agencija za zaštitu okoliša preporučuje dnevnu i noćnu razinu do 45 dB.
Zvukove koji stvaraju buku u jedinicama intenzivnog liječenja čine medicinsko i nemedicinsko osoblje: hodanjem, razgovorima, promjenama položaja predmeta, svakodnevnim medicinskim i nemedicinskim aktivnostima; uz brojne elektroničke uređaje i uređaje za monitoring koji svojim alarmnim sustavom dodatno pridonose ukupnoj buci. Pretjerana buka u radnom okolišu utječe na fluktuiranje pažnje, pad koncentracije zdravstvenih djelatnika te može pojačati simptome povezane sa stresom, a sve to često dovodi i do promjena ponašanja, iritabilnosti i socijalnih problema unutar tima. U ovom preglednom radu korištena je metoda pretraživanja dostupne literature, a koja je korespondirala s temom i ciljem rada. Prikazan je utjecaj okolišne buke na zdravstvene djelatnike u jedinicama intenzivnog liječenja. Također, prikazane su moguće mjere smanjenja buke u svrhu zaštite navedenih zdravstvenih djelatnika.
New finds of fauna and flora from the locality Krsmol (Upper Carboniferous, Ploužnice Horizon) in the Krkonoše Piedmont Basin (Bohemian Massif )
Authors: Štamberg Stanislav
Published: October 2024

The paper presents new finds of fossil fauna and flora at the rediscovered locality Krsmol “Deep gorge” (“Hluboká rokle”) of the Ploužnice Horizon (Semily Formation, Krkonoše Piedmont Basin). Several metres thick reddish to grey tuffaceous siltstones of this lacustrine horizon contain 10 centimetres thick layer of grey, hard, siltstones with good fissility, containing one to two thin layers enriched in isolated osteological fragments of vertebrates at the base. Scales and teeth of actinopterygians, scales and fragments of the pectoral girdle of acanthodians are common, and teeth of chondrichthyans can be occasionally found. Rare scales of actinopterygians, isolated insect wings and sporadic plant remains are also present in the overlying reddish-purple siltstone. The newly found fauna in Krsmol extends the existing knowledge based on the old collections and coincides in species with the findings at other sites of the Ploužnice Horizon. From the biostratigraphic point of view, the findings of scales of actinopterygian fish Sphaerolepis kounoviensis, which is an important representative of the biozone corresponding to the uppermost Carboniferous shark teeth and especially the wings of the insect Sysciophlebia rubida of the family Spiloblattinidae are significant, on the basis of which the strata can be classified as Stefan B/C (Kasimovian/Gzhelian) similarly to the strata at other sites of the Ploužnice Horizon.
Corkite and metatorbernite from the Kosobody uranium occurrence at Jesenice (Czech Republic)
Authors: Žáček Vladimír , Laufek František , Škoda Radek
Published: October 2024

Corkite and metatorbernite occur in the supergene zone of uranium mineralization at an abandoned exploration shaft No 36 situated about 1 km NW from the village of Kosobody at Jesenice in the Rakovník District. The locality was explored for uranium in 1954–1959 and subsequently in 1970–1972 (Mrázek 1972). The mineralization is confined to discordant mm–cm thick veinlets in brecciated phyllite. The veinlets are composed of quartz, barium-rich K-feldspar, “limonite” (goethite), kaolinite, metatorbernite and corkite. The country rock is Neoproterozoic phyllite of the Teplá-Barrandian Zone (Chlupáč – Štorch 1992, Kopecký et al. 1997, Klomínský et al. 2010). The samples were collected in 2021 and studied by PXRD and in carbon-coated polished sections by EMPA. Metatorbernite forms apple-green, thin tabular to lamellar crystals 0.1–1 mm in size (Fig. 1a, b). In the thin section, it also forms more massive fillings and radiating aggregates up to several millimeters (Fig. 2a–c, Fig. 3a). EMPA showed good agreement with the theoretical formula. The content of barium fluctuates in the range of 0.0–5.51 wt. % BaO, which corresponds up to 36 mol. % of metauranocircite component. The mean empirical formula is: (Cu0.79Ba0.12Ca0.03) (UO2)2.03(PO4)1.98 · 8 H2O, see Table 1. The lattice parameters calculated for the Space Group P4/n: a = 6.9647(8) A, c = 17.322(2) A, V = 840.2(2) A3 are in good agreement with published data (compare Table 2). Corkite forms isometric or irregular accumulations up to 1 mm in size of yellow colour, which are mostly brown cloudy, intergrown ith metatorbernite and are often surrounded by aggregates of “limonite” (goethite) and kaolinite flakes (Fig. 2a–c). In BSE, corkite aggregates show irregular darker and lighter domains (Fig. 3b). Lighter domains have slightly higher Pb contents, otherwise the differences in chemical composition are negligible. To calculate the empirical formula, the numbers of atoms were normalized to the sum T-site elements = 2. The mean empirical formula: (Pb0.99U0.04)(Fe2.85Al0.26) [(PO4)1.46 (SO4)0.49] (OH)6, displays a significant predominance of P over S. The data are thus plotted near the corkite – kintoreite boundary in the ternary P – As – S diagram (Fig. 4). The Al, which partly replaces Fe3 , indicates 4–12 mol. % of isomorphic admixture of hinsdalite, ideally PbAl3(PO4)(SO4)(OH)6. There is also low but omnipresent content of uranium (0.03–0.05 U apfu, see Table 3), which was not reported among minerals of the crandallite group (Fig. 5). The lattice parameters a = 7.265(3) A, c = 16.87(1) A, V = 771.5(6) A3, calculated for the Space Group R3m, are in the agreement with the published data (compare Table 4).
The use of thermal camera on UAV in the research of the landslide area the village of Březno u Postoloprt
Authors: Kořínková Barbora , Kýhos Martin , Koucká Lucie , Jelének Jan
Published: October 2024

Landslides are complex geological phenomena that can cause significant damage to property and infrastructure and put public safety at risk. For mitigation of these risks, monitoring of landslides is essential. The application of thermal imaging on board unmanned aerial vehicles (UAVs) represents one of the recently developing methods for landslide monitoring. The thermal imaging can be used to detect changes in surface temperature that are associated with landslide deformation. In this study, the Workswell WIRIS 2nd gen 640 thermal camera on the UAV DJI Matrice 600 Pro (Fig. 1) was used to investigate a landslide in Březno u Postoloprt (Fig. 2). This small-scale active rotational landslide occurs in Cretaceous marlstones with a variety of deformation features, including cracks, gullies, and toppling. The flight was planned considering the local topography, vegetation season and weather. It took place in October 2022, during constant cloud cover, approximately at an altitude of 27 meters above the terrain using the pilot-controlled mode. The final spatial resolution was 2.92 cm per pixel with approximate image overlap of 90 %. The thermal orthomosaic was analysed using a standard deviation threshold-based classification algorithm (Fig. 3), where the threshold defining the deformation features was set as 2,5 times standard deviation from mean temperature. Based on the algorithm, pixels with temperatures below 13.4 °C were identified as potential landslide deformation features (Fig. 4). These features were then verified using the 3D photogrammetric model (Fig. 5). The results of the study showed that the thermal orthomosaic was able to successfully detect the main system of cracks that runs perpendicular to the slope of the landslide. These thermal anomalies may results from the air circulation in the fractures, cooling caused by evaporation in the higher-moisture zones or the shadowing effect of the terrain roughness. The findings of this study suggest that UAV thermal imaging represents a promising tool for landslide monitoring upon condition that a number of factors such as the vegetation cover, actual temperature, the aspect of the slope and its exposure to the sunlight during the day are taken in account before making conclusions. The results of UAV thermal imaging should be also interpreted in conjunction with other data, such as RGB and multispectral imaging and ground-based observations. Thanks to easy implementation, the UAV thermal imaging represents an effective option for landslide monitoring.
NEITHER CREATED NOR DESTRUCTIBLE
Authors: Arif Syamsuddin

This article discusses Ibn Sīnā’s reasons for upholding the eternity of the world in his major philosophical writings and the ensuing heated debate between his detractors (al-Ghazālī, al-Shahrastānī and al-Rāzī) and supporters (al-Ṭūsī and al-Āmidī). I argue that notwithstanding the responses and surrejoinders it had elicited, Ibn Sīnā’s position on the issue is indeed coherent and irrefutable, since he distinguishes three modes of eternity, corresponding to the hierarchy of beings which he introduced, namely, (i) absolutely eternal (by virtue of itself); (ii) relatively eternal (by virtue of something else); and (iii) not eternal both considered per se as well per aliud. With this distinction he evades both horns of the dilemma: either the universe is eternal or it is not eternal. On Ibn Sīnā’s account, therefore, the universe is both eternal and not eternal. It is eternal because the efficient cause that necessitates and sustains its existence is eternal, but also not eternal in view of its essential contingency.

The present work focuses on the behavior of the stopping power of a polymer gel dosimetry system, known as PAGAT,infused with high atomic number nanoparticles formed by gold, with a 1 % mass concentration. The study is carried out for different energies of electron and proton beams within ranges of therapeutic applications, first by theoretical assessment, and then by simulation with Monte Carlo codes: PENELOPE in the case of electrons, and FLUKA in the case of protons. The results obtained analytically show promising behavior for gold nanoparticle infused tissue-equivalent systems, while the simulation results show better correspondence with models that consider the net path traveled, instead of models based on the thickness of the samples as typically done in experimental determinations.

Forecasting the number of road accidents in Poland using trend models depending on the days of the week
Authors: Gorzelanczyk Piotr
Published: October 2024

Every year a very large number of people die on the roads. From year to year, the value decreases, there are still a very high number of them. The pandemic has reduced the number of road accidents, but the value is still very high. For this reason, it is necessary to know on which days the highest number of traffic accidents occur, and to know the forecast of accidents by day of the week for the coming years, so that we can do everything possible to minimize the number of traffic accidents. The purpose of the article is to make a forecast of the number of road accidents in Poland according to the day of the week. The research was divided into two parts. The first was the analysis of annual data from the Police statistics on the number of road accidents in Poland in 2000-2021, and on this basis the forecast of the number of road accidents for 2022-2031 was determined. The second part of the research, dealt with monthly data from 2000-2021. Again, the analyzed forecast for the period January 2022 - December 2023 was determined. The results of the study indicate that we can still expect a decline in the number of accidents in the coming years, which is particularly evident when analyzing annual data. It is worth noting that the prevailing pandemic distorts the results obtained. The research was conducted in MS Excel, using selected trend models.

لم تنجح حكومة السودان بتحقيق سلام مستدام رغم توقيعها على العديد من اتفاقات السلام، كذلك لم تنجح في إقناع الحركات المسلحة التي وقعت معها تلك الاتفاقات بالانخراط في الحياة المدنية والكف عن العودة إلى العمليات المسلحة. يناقش هذا التقرير سياسات وبرامج نزع السلاح والتسريح وإعادة الإندماج الواردة في اتفاقات السلام بعد استقلال السودان في عام ١٩٥٦. فمنذ اتفاق أديس أبابا وحتى اتفاق جوبا للسلام، شهدت سياسات نزع السلاح والتسريح وإعادة الاندماج تقدماً ملحوظاً على مستوى الأحكام القانونية والمؤسسات ذات الصلة. لكن الممارسة والتطبيق كانا ضعيفين للغاية وغير مناسبين. ويشكل فشل برامج نزع السلاح والتسريح وإعادة الاندماج تهديداً مستمراً لعملية بناء سلام مستدام في السودان. لقد أدى الفشل المتكرر في إعداد وتنفيذ سياسات وطنية مناسبة لإقامة سلام عادل ومستدام في السودان إلى تكرار العودة إلى الحرب بشكل أعنف في كل مرة. يسلط هذا التقرير الضوء على تلك الاتفاقات، ويضع صانعي السياسات العامة على المستويين الوطني والدولي بصورة التجارب السابقة والدروس المستفادة.

Five coordination compounds of the general formula [LnL2(NO3)3]n (Ln3+ = Eu (I), Sm (II), Tb(III), Dy (IV), and Gd (V)) are synthesized from 2-[((4-chlorophenyl)amino)methylene]-5,5-dimethylcyclohexane-1,3-dione (L). The crystal structures of the ligand and complex III are determined by X-ray diffraction (XRD) of single crystals (CIF files CCDC nos. 2298715 (L) and 2298716 (III)). Complex III is polymeric due to the bidentate-bridging coordination of the ligand by the oxygen atoms of the cyclohexanedione fragment, and the coordination number of the central atom is ten. According to the phase XRD data, all synthesized polycrystalline compounds are isostructural to the single crystals of complex III. The photoluminescence properties of the ligand and coordination compounds in the polycrystalline state are studied. The energy transfer from the ligand to lanthanide(III) ion is shown to proceed via the “antenna” mechanism in the case of the europium(III), samarium(III), and terbium(III) compounds. Among the series of the complexes, the highest quantum yield is observed for compound I (21.9%), and the sensibilization efficiency of the europium(III) complex is 43.5%.

The reactions of cobalt(II) nitrate or perchloride with acetamide (AA) or carbamide (Ur) in an aqueous medium produce coordination compounds [Co(Ur)4](NO3)2 (I), [Co(Ur)6](NO3)2 (II), [Co(AA)4(H2O)2](NO3)2 (III), [Co(AA)4(H2O)2](NO3)2 ∙ 2AA (IV), [Co(Ur)6](ClO4)2, (V), [Co(AA)4(H2O)2](ClO4)2 (VI), and [Co(AA)6](ClO4)2 (VII). The compositions of the isolated complexes are determined by physicochemical methods, and the crystal and molecular structures of compounds II, V, VI, and VII are solved. Specific features of the thermal behavior of all synthesized compounds in a wide temperature range are studied in detail. These compounds are shown to be used as precursors in the preparation of nanosized Co3O4 using self-propagating high-temperature synthesis. The catalytic activity of thus synthesized Co3O4 in the model epoxidation of allyl alcohol is studied.

The reaction of 1,4,7-trimethyl-1,4,7-triazacyclononane with samarium, gadolinium, and terbium chloride tetrahydrofuranates gives mononuclear complexes [LnCl3(Me3tacn)(THF)n] (Me3tacn = 1,4,7-trimethyl-1,4,7-triazacyclononane; Ln = Sm (I), Gd (II), n = 1; Ln = Tb (III), n = 0). The treatment of complexes I or II with 1,2,4-triphenylcyclopentadienyl potassium affords mono(cyclopentadienyl) complexes [CpPh3LnCl2(Me3tacn)] (CpPh3 = = 1,2,4-triphenylcyclopentadienyl; Ln = Sm (IV), Gd (V)). Complexes IV and V are formed even when a twofold excess of CpPh3K is used. The molecular structure of complexes I–V was established by X-ray diffraction analysis (CCDC nos. 2299485 (I), 2299487 (II), 2299486 (III), 2305352 (IV), 2306051 (V)).

The reactions of the dilithium derivatives of 9,12-dihalogen-ortho-carboranes 1,2-Li2-C2B10H8-9,12-X2 (X = Cl, Br, I) with mercury chloride HgCl2 afford a number of complexes of the chloride ion with the halogen derivatives of [12] mercuracarborand-4: {[(9,12-X2-C2B10H8-1,2ʹ-Hg)4]Cl}Na · nH2O. The molecular crystal structure of the complex of the[12]mercuracarborand-4 octaiodine derivative with the chloride ion is determined by X-ray diffraction. The substituents at the periphery of the mercury-containing macrocycle are found to exert a substantial effect on the macrocycle geometry leading to the transition from the planar to butterfly conformation, whose geometry is predetermined by a set of intermolecular interactions in the crystal.
The Problem of the Shortage of Fresh Water in Egypt and the Possibilities of Its Solution
Authors: Volkov S. N
Published: October 2024

The population growth rates that increased after the 1952 revolution accelerated the decline in the supply of fresh water to Egyptians due to the exhaustion of its traditional sources. As a result, at the turn of the 1980s – 1990s, Egypt has overcome the water deficit limit of 1000 m3 per person per year. In order to reduce water stress, the Government of the country in the second half of the twentieth century pursued a policy of birth control and reduction of cultivation of moisture-loving crops. Since the beginning of the 21st century, with the slow introduction of modern irrigation methods, it has focused on increasing the reuse of treated drainage waters in agriculture and the construction of seawater desalination plants to meet the needs of industry and public utilities. The Egyptian Government sees prospects for solving the problem of water scarcity, the growth rate of demand for which in the 21st century will decrease as population growth and economic development slow down, in the achievements of scientific and technological progress and the widespread use of cheap water treatment technologies.

Construction work is divided into different scopes of work, including structural, architectural, MEP and others. The structure is a means that functions to distribute live loads and dead loads into the ground. One part of the structure is the foundation which is a part of the building construction whose task is to place and transmit the load of the upper part of the building to the subgrade. The selection of the type of foundation structure is carried out by taking into account the condition of the soil, the limitations imposed by the structure above it, the limitations of the surrounding environment, the cost and time of carrying out the work. For example, the Majalengka District Attorney's building construction project uses a Strauss Pile foundation as the lower. Strauss foundation is a type of foundation that is used to carry loads when hard soil that has a strong bearing capacity is located very deep from the ground surface. In this project, the implementation of the Strauss Pile work refers to the provisions that must have the ASTM D 1143-81 standard regarding static compressive loading, using concrete quality K300 and reinforcing steel Ø ≥ 10 BJTD 40 and Ø≤ 10 BJTP 24.

In the modern era, face recognition is one of the important technologies used in various security and data analysis applications. This paper aims to use Python to implement the K-Nearest Neighbors (KNN) algorithm to detect gender and age through face recognition. The main problem faced is the accuracy in classifying gender and estimating age from various facial images with lighting, pose, and expression. This study uses various steps to collect facial data, use image processing techniques to extract features, and use the KNN algorithm for classification. The results show that applying KNN can detect gender and age from faces with sufficient accuracy, although there are some problems with extreme lighting and pose conditions. These findings indicate that the KNN algorithm can be used in facial recognition applications to detect gender and age. By fixing parameters and improving data quality, further improvements can be achieved.
