Pressure Ulcer Management Virtual Reality Simulation (PU-VRSim) for Novice Nurses: Mixed Methods Study
Authors: Jung Soo Youn , Moon Kyoung Ja 
Published: April 2024

Background
Pressure ulcers (PUs) are a common and serious complication in patients who are immobile in health care settings. Nurses play a fundamental role in the prevention of PUs; however, novice nurses lack experience in clinical situations. Virtual reality (VR) is highly conducive to clinical- and procedure-focused training because it facilitates simulations.

Objective
We aimed to explore the feasibility of a novel PU management VR simulation (PU-VRSim) program using a head-mounted display for novice nurses and to investigate how different types of learning materials (ie, VR or a video-based lecture) impact learning outcomes and experiences.

Methods
PU-VRSim was created in the Unity 3D platform. This mixed methods pilot quasi-experimental study included 35 novice nurses categorized into the experimental (n=18) and control (n=17) groups. The PU-VRSim program was applied using VR in the experimental group, whereas the control group received a video-based lecture. The PU knowledge test, critical thinking disposition measurement tool, and Korean version of the General Self-Efficacy Scale were assessed before and after the intervention in both groups. After the intervention, the experimental group was further assessed using the Clinical Judgment Rubric and interviewed to evaluate their experience with PU-VRSim.

Results
The results compared before and after the intervention showed significant improvements in PU knowledge in both the experimental group (P=.001) and control group (P=.005). There were no significant differences in self-efficacy and critical thinking in either group. The experimental group scored a mean of 3.23 (SD 0.44) points (accomplished) on clinical judgment, assessed using a 4-point scale. The experimental group interviews revealed that the VR simulation was realistic and helpful for learning about PU management.

Conclusions
The results revealed that PU-VRSim could improve novice nurses’ learning of PU management in realistic environments. Further studies using VR for clinical training are recommended for novice nurses.

Authors: Abbas Nasir , Raza Muhammad Ali , Paracha Zainab , Shahid Muhammad Sadiq 
Published: April 2024

Purpose: This study examines the internal factors that are influencing profitability in Pakistani Islamic banks during the period 2016-2021.
Design/Methodology/Approach: The analysis utilizes panel data regression models to address potential estimation bias.
Findings: The study covers key Pakistani Islamic bank financial performance criteria. Internal factors significantly affect ROE and EPS. Gearing and capital ratios enhance ROE/EPS. Due to increased capitalization and leverage, Islamic banks' capital management is vital to profitability. ROE and NIM models are affected by deposits. Deposit funding drives Islamic bank profitability and interest income. In the NIM model, liquidity and NPL ratios affect ROE and EPS significantly. Asset quality and liquidity management effect interest income, not profits. Bank size does affect ROE and EPS models, which is notable in the findings. Islamic financial institutions can prioritize specialization and efficiency over expansion. These numbers indicate Pakistani Islamic banks' finances. Capitalization, leverage control, and deposit mobilization are key to financial success, while risk management ensures stability and profitability during economic downturns.
Implications/Originality/Value: The detailed investigation shows Pakistan's Islamic banking profitability. Deposit management, capital structure, and asset quality impact profitability. Capitalization and leverage improve earnings, therefore financial management matters. Deposit management is vital to profitability since it affects performance. Recession-sensitive Islamic banks show resiliency. NPA mitigation and liquidity management affect net interest margin, as a key driver. This research offers valuable insights for internal management strategies and regulatory frameworks aimed at enhancing the stability and growth of Islamic banking in the region.

Background: Urinary calculi, particularly staghorn renal calculi, pose a significant health challenge. Percutaneous nephrolithotomy (PCNL) and open surgery are two distinct surgical interventions employed for treating staghorn renal calculi. This study aimed to compare the stone clearance rates of patients undergoing open surgery versus percutaneous nephrolithotomy at the Department of Urology, Sindh Institute of Urology and Transplantation (SIUT) in Karachi, Pakistan.
Methodology: A prospective cohort study was conducted from February 8th to August 7th, 2019. Patients aged 18 to 60 years, diagnosed with staghorn renal calculi, were included. Patients with other renal stones and untreated urinary tract infections were excluded. The study enrolled 230 patients, divided into two groups: Group I underwent percutaneous nephrolithotomies, and Group II underwent open surgery. Stone clearance was assessed through post-surgery X-ray KUB.
Results: The mean age of participants was 44.99 years, with a balanced gender distribution. Both PCNL and open surgery achieved stone clearance rates of 68.7%, with significantly higher rates observed in the PCNL group (74.8% vs. 62.6%, p = 0.04). Stratification by age, gender, illness duration, and stone location did not yield substantial variations in stone clearance rates.
Conclusion: PCNL demonstrated a superior stone clearance rate compared to open surgery in the treatment of staghorn renal calculi. This finding highlights the potential of PCNL as a more effective intervention for addressing this challenging urological condition.

Regional Clustering Based on Types of Non-Communicable Diseases Using k-Means Algorithm
Authors: Munandar Tb Ai , Yunizar Yusuf Pratama Ajif 
Published: April 2024

Noncommunicable diseases (NCDs) have become a global threat to public health, necessitating a comprehensive understanding of their geographic and epidemiological distribution in order to devise appropriate interventions. The objective of this study is to clustering areas of Banten Province based on NCDS profiles using the unsupervised learning technique. The method used in this study is the k-means algorithm for grouping types of non-communicable diseases based on region. The processing and normalisation of NCDS prevalence data from various health sources preceded cluster analysis using the k-means clustering algorithm. This research is categorised into two scenarios: the first involves the clustering of data obtained from outlier analysis, while the second scenario excludes any outliers. The objective is to observe disparities in regional clustering outcomes by categorising non-communicable diseases according to these two scenarios. The silhouette index is used to determine the validity of cluster results. These findings are analysed in depth to determine the geographic and socioeconomic patterns associated with each cluster's NCDS profile. Based on the mean silhouette index value of 0.812, the results indicate that the sum of k = 2 in the k-means algorithm is the optimal cluster result in this case. Five non-communicable diseases, namely diabetes, hypertension, obesity, stroke, and cataracts, necessitate significant focus in the first cluster (C1), where 202 regions were grouped. Six regions belong to the second cluster (C2), which includes areas that are not only susceptible to the five non-communicable diseases in cluster C1 but also to breast cancer, cervical cancer, heart disease, chronic obstructive pulmonary disease (COPD), and congenital deafness.
Odyssées décoloniales : la figure d'Ulysse dans les œuvres poétiques de Césaire, Campos et Walcott
Authors: Silva Rafael 
Published: April 2024

La figure d'Ulysse est souvent présente dans la littérature moderne et contemporaine. À partir d'un bref panorama historique sur la constitution de l'espace littéraire mondial, nous essayons de comprendre la présence d'Ulysse dans trois grandes œuvres de la littérature décoloniale produite dans le « Nouveau Monde » : celles d'Aimé Césaire (1913–2008), de Haroldo de Campos (1929–2003) et de Derek Walcott (1930–2017). Au-delà des spécificités linguistiques et culturelles, notre hypothèse est que la figure d'Ulysse, incarnant la tradition classique (gréco-romaine), joue un rôle fondamental – quoique paradoxal – dans le projet littéraire décolonial de l’écrivain martiniquais (francophone), aussi bien que dans celui du Brésilien (lusophone) et du Saint-Lucien (anglophone).

For the first time, data were obtained proving the modification of the activation of the pituitary-testicular complex of male house mice under the influence of early postnatal experience and the maternal environment when exposed to the odor of receptive females of their own and closely related species. We have confirmed the conjugacy of the formation of behavioral and physiological mechanisms of precopulatory isolation in early ontogenesis. The serum level of free testosterone in males of closely related species M. spicilegus and M. m. wagneri differ, it is significantly lower in mound-building mice. The level of free testosterone of males fostered by a conspecific female was significantly lower when they exposed a heterospecific in comparison with a conspecific female odor. The rearing of M. m. wagneri males by females of a closely related species caused a decrease in the testosterone response of males to the exposure of chemosignals from a female (both con-and heterospecific) and led to the absence of differences in the serum level of free testosterone when they exposed to the odor of a female of their own or closely related species. The data obtained indicate a significant influence of the rearing conditions on the formation of hormonal mechanisms of reproductive isolation.

Biotite-garnet-sillimanite-cordierite gneisses from the Leshchev zone of the Middle Volga megablock in the Volga-Ural segment of the East European craton have been studied. The obtained Sm-Nd model age of the rocks is 2.8 Ga. U–Pb isotope-geochronological study of zircon cores from these rocks was carried out. The CL images revealed several generations of the zircon cores. The obtained age of the main sources of detrital zircon is 2.58 Ga. Single zircon grains have ages of cores of 2.4, 2.7, and 3.1 Ga. The calculated ɛNd(2500) = = –0.6 indicates the crustal or mixed mantle-crustal nature of the protolith of these gneisses. High-alumina metaterrigenous rocks of the Bolshecheremshanskaya Group, the Leshchevskaya zone, and the South Volga supracrustal complex are considered as elements of time and spatial secuence of sediments of Neoarchean and Paleoproterozoic basins with a protoplatform base and a passive continental margin, successively replacing each other.

Upper Muna kimberlite field) showed that the crust at different levels is composed of pyroxene, garnet-pyroxene crystalline schists and garnet-pyroxene gneisses. Exsolution textures in pyroxenes and amphiboles, granat rims around grains of ilmenite and pyroxenes indicate that the mineral associations of crystalline schists were formed during cooling at constant pressure. Р–Т equilibrium parameters indicate that garnet-pyroxene crystalline schists are present in the middle crust (P = 7–8 kbar), while garnet-pyroxene gneisses can be considered as rocks of the lower crust (P = 9–10.1 kbar). For the first time, sodalite was found in xenoliths of crystalline schists, which indicates the presence of brines with a high concentration of NaCl at the final stages of rock cooling. The determination of the U–Pb age of zircons testifies to the Neoarchean (2.7 Ma) tectono-thermal event, accompanied by the melting of the crust. In the garnet–pyroxene gneisses, the 1.9 stage is weakly manifistated. The obtained data confirm the earlier conclusion about the vertical and lateral heterogeneity of the crust of the Yakutsk diamondiferous province and the absence of dependence between the degree of crust reworking and spatial location relative to the main collision zones of the Siberian craton.

In the Polar Urals, there are few small granitoid intrusions (Yarkeu, Yayu and Pogurei complexes), which are usually associated with the Ural collision. Their Carboniferous-Early Permian age, in most cases, is based on methodologically outdated K/Ar dates, and is also assumed from field geological relationships. We have studied the monzonitoids of the Yarkeu petrotypical pluton, one of the largest such intrusions, and for the first time obtained Late Precambrian U–Pb LA-ICP-MS (zircon) and 40Ar/39Ar (amphibole) ages of 687 ± 3, 669 ± 8 Ma years, respectively. Water-saturated fluid regime (presence of magmatic amphibole and high water content in it, 4.5–5.6 wt %,), hypabyssal formation conditions (P = 2.1–3.5 kbar, T = 871–960°C), features of the chemical composition of monzonitoids (low TiO2 (0.6–0.8 wt %) and CaO (3.6–6.3 wt %) contents, high Al2O3 (16.6–18.0 wt %) and K2O (1.7–4.6 wt %), enrichment in large-ion lithophile elements relatively high field strength and rare earth elements, Ta-Nb minimum and Pb maximum), as well as metallogenic specialization in Cu and Mo (±Pb, Hg, Au), indicate the formation of the rocks of the Yarkeu complex in a subuction-related setting in a fairly thick continental crust. Isotopic clocks in these monzonitoids captured two stages of the assembly of the Pangea supercontinent: the earliest stage in the Late Precambrian, when monzonitoids were formed on the active Bolshezemel margin of Arctida, and one of the final stages in the Middle to Late Carboniferous, when the rocks underwent metamorphism due to the closure of the Paleo-Ural ocean and the onset of collision between Arkt-Laurussia and Siberia.

Published: April 2024

A paleoclimatic reconstruction of the last 14 ka years was carried out based on the results of GPR sounding, spore-pollen analysis and radiocarbon dating of a peat section (7 m) located in a model bog of the Valdaisky National Park (Novgorod Region). Peat accumulation rates varied from 0.075 mm per year during the Late Glacial to 0.15–1.15 mm per year during the Boreal stage (when the levels of the Valdaian lakes dropped 10 m) and 4.25 mm/year in recent centuries. Numerous cycles of Holocene warming/cooling events were within ±1–2°C compared to the current ones and were accompanied by moderate fluctuations in annual precipitation (±25–50 mm). The greatest amount of forest compositional change took place during the Atlantic period, when spruce–broad-leaved forests and oak forests dominated. In the last two millennia, the vegetation dynamics of the region were mainly influenced by agricultural activity.

Published: April 2024

The effect of alkalinization of fulvic acids (FA) solutions on an increase in their optical density is studied. To explain the observed phenomenon, the investigation of FA particles in solutions with different pH was carried out using scanning electron microscopy (SEM) and scanning tunneling microscopy (STM). It was found that with an increase in pH, there is a noticeable decrease in the size of the observed supramolecular formations from FA from about 200 to 100 nm, and when studying FA samples on STM, it was shown that FA in solutions exist in the form of supramolecular formations several hundred nanometers in size, formed by particles-molecules of FA 10–20 nm. An explanation of the observed phenomenon was proposed based on existing ideas about the supramolecular fractal-cluster organization of humic substances (HS). It consists in the fact that the upper layer of F-clusters disintegrates into particles-molecules of FA with a decrease in their size observed with the help of SEM. At the same time, particles-molecules of FA due to their small size are not visible with the help of SEM, but they are well visualized when using STM.
AVERAGED CIRCULAR SPATIAL RESTRICTED THREE-BODY PROBLEM: INTERNAL CASE, NEW RESULTS

Published: April 2024

We investigate the spatial restricted circular three-body problem in the nonresonant case. Namely, we apply Gaussian averaging to obtain averaged equations in terms of osculating elements and then investigate them. Keplerian ellipse with a focus in the main body (the Sun) is taken as an unperturbed orbit assuming the semi-major axis of the ellipse to be less than the radius of the orbit of the outer planet (internal problem). Using the Parseval formula we have derived the twice-averaged perturbed force function of the problem in the form of an explicit analytical series with coefficients expressed in terms of the Gauss and Clausen hypergeometric functions. An investigation of averaged force function along it’s curves of non-analyticity showed that the series are asymptotic by Poincaré. For a reduced system with one degree of freedom, phase portraits of oscillations in the plane of the Keplerian elements \(e\), \(\omega \) are constructed in the second and fourth approximations. It is shown the topology of the phase portrait is more complicated in fourth approximation then in first and second approximations provided that the constant \({{c}_{1}}\) of the Lidov–Kozai integral belongs to the interval (0, 0.382).
