Authors: Chandra Julius Adi Chandra , Rian Sacipto  , Muktiono Muktiono
Published: July 2023

Sustainable Finance is one of the government's steps in preserving the Environment. A concrete form of sustainable finance is an ESG-based sustainable investment. Financial Service Institutions, Issuers, Banks, and Public Companies are required to implement Sustainable Finance in order to achieve a national economy that grows stably, inclusively, and sustainably and can prevent forms of investment in business activities that use excessive resources that have the potential to damage the Environment, these demands are based on POJK Number 51 /POJK.03/2017. However, the regulation still does not regulate specific classifications and indicators for companies that do use nature as one of their business prospects, as a result of which Greenwashing practices often occur indirectly. Therefore, according to the author, OJK as an institution in charge of regulating and supervising financial services activities in the Banking sector, Capital Market sector, and IKNB sector, must make special arrangements related to Greenwashing practices so as to eliminate ambiguity in implementing Sustainable Finance in ESG-based Sustainability Investment strategies.

Pore Structure and Fractal Characteristics of Mixed Siliciclastic-Carbonate Rocks from the Yingxi Area, Southwest Qaidam Basin, China
Authors: Zhang Xinlei , Gao Zhiqian , Maselli Vittorio , Fan Tailiang
Published: July 2023

Evaluating reservoir properties at the pore scale is vital to better estimate hydrocarbon reserves and plan field development. The lacustrine mixed siliciclastic-carbonate deposits of the Upper Paleogene Xiaganchaigou Formation in the west Yingxiongling area form one of the most important hydrocarbon reservoirs in the southwestern Qaidam Basin (China). In this study, we analyzed well samples with X-ray diffraction (XRD), nuclear magnetic resonance (NMR), and mercury injection capillary pressure (MICP) data in integration with scanning electron microscopy (SEM) images to decipher the mineral composition and pore structure characteristics of the Xiaganchaigou Formation. We also calculate the fractal dimensions using MICP, NMR T2 spectrum, and SEM images based on fractal theory models. The results indicate that the mixed siliciclastic-carbonate samples of the upper section of the Xiaganchaigou Formation are mainly formed by dolomite and clay minerals with low siliceous and calcite content. Porosity is relatively low (2.01−9.83%) and positively correlated with dolomite content, thus indicating that the dolomite intercrystalline pores formed by infiltration and reflux dolomitization control the reservoir characteristics. The size of dolomite intercrystalline pores varies between several and hundreds of nanometers. The porosity has a poor correlation with permeability, which indicates that the pores are mostly primary, which lack the transformation of late dissolution. Three types of mixed siliciclastic-carbonate reservoirs are identified according to pore size distribution (<20 nm, 20−300 nm and multiple distribution), calculated using the NMR T2 spectrum. Fractal curves calculated by combining the MICP and NMR data are characterized by multisegments. The number of segments depends on the degree of heterogeneity of pore structure: two segment for high heterogeneity and three segment for low heterogeneity, also indicating a multifractal feature in mixed rock reservoirs. There is a negative correlation trend between porosity and fractal dimensions, and larger pores often have larger fractal dimensions. These results show that MICP-based fractal values are higher than those of NMR-based, which result from unconnected pores that the MICP is unable to reach. Fractal dimensions obtained from SEM have a small and narrow distribution range and are negatively correlated with the number of pores with smaller sizes. In essence, this study shows that the fractal dimension can be a concise index to evaluate the heterogeneity of lacustrine mixed siliciclastic-carbonate reservoirs, which can serve as an important reference for hydrocarbon development plans.

Published: July 2023

Iron sulfide (FeS) scale is a known problem that can significantly impact oil and gas (O&G) production. However, current monitoring methods cannot detect the problem at early stages, not until it is too late for any meaningful remedial action. Spectral induced polarization (SIP) is an established geophysical method increasingly used in near-surface environmental applications. The unique characteristics of the SIP method, mainly the sensitivity to both bulk and interfacial properties of the medium, allow for the potential use as a characterization and monitoring tool. SIP is particularly sensitive to metallic targets, such as FeS, with direct implications for the detection, characterization, and quantification of FeS scale. In a column setup, various concentrations of pyrite (FeS2), a common form of FeS scale, within calcite were tested to examine the SIP sensitivity and establish qualitative and quantitative relationships between SIP signals and FeS2 properties. The concentration of FeS2 in the samples directly impacts the SIP signals; the higher the concentration, the higher the magnitude of SIP parameters. Specifically, the SIP method detected the FeS2 presence as low as 0.25% in the bulk volume of the tested sample. This study supports the potential use of SIP as a detection method of FeS2 presence. Furthermore, it paves the way for upcoming studies utilizing SIP as a reliable and robust FeS scale characterization and monitoring method.
Protocol for a scoping review study on learning plan use in undergraduate medical education
Authors: Romanova Anna , Touchie Claire , Humphrey-Murto Susan , Ruller Sydney , Cole Victoria
Published: July 2023

Background
The current paradigm of competency-based medical education and learner-centredness requires learners to take an active role in their training. However, deliberate and planned continual assessment and performance improvement is hindered by the fragmented nature of many medical training programs. Attempts to bridge this continuity gap between supervision and feedback through learner handover have been controversial. Learning plans are an alternate educational tool that help trainees identify their learning needs and facilitate longitudinal assessment by providing supervisors with a roadmap of their goals. Informed by self-regulated learning theory, learning plans may be the answer to track trainees’ progress along their learning trajectory. The purpose of this study is to summarize the literature regarding learning plan use specifically in undergraduate medical education and explore the student’s role in all stages of learning plan development and implementation.
Methods
Following Arksey and O’Malley’s framework, a scoping review will be conducted to explore the use of learning plans in undergraduate medical education. Literature searches will be conducted using multiple databases by a librarian with expertise in scoping reviews. Through an iterative process, inclusion and exclusion criteria will be developed and a data extraction form refined. Data will be analysed using quantitative and qualitative content analyses.
Discussion
By summarizing the literature on learning plan use in undergraduate medical education, this study aims to better understand how to support self-regulated learning in undergraduate medical education. Results from this project will inform future scholarly work in competency-based medical education at the undergraduate level and have implications for improving feedback and supporting learners at all levels of competence.

Real-life impacts of olipudase alfa: The experience of patients and families taking an enzyme replace therapy for acid sphingomyelinase deficiency
Authors: Raebel Eva M , Wiseman Samantha , Donnelly Conan Brian , Mathieson Toni , Poutney Jackson , Crowe Joslyn , Hopkin Justin
Published: July 2023

Background:
Acid Sphingomyelinase Deficiency (ASMD) is an ultra-rare autosomal recessive lysosomal storage disorder characterized by intracellular lipid accumulation because of the reduced function of acid sphingomyelinase. Olipudase alfa, an enzyme replacement therapy, was recently approved in several countries for the treatment of the non-neurologic manifestations of ASMD. Studies demonstrate improvement in organomegaly, pulmonary function and lipid profiles with olipudase alfa, yet little is known about its impact on quality of life (QoL) for patients and caregivers. The purpose of this study is to better understand the real-life impact of ASMD on patients and caregivers and assess how olipudase alfa impacts QoL for pediatric patients and their caregivers.
Methods:
Parents of pediatric patients (≤ 18 years of age) with a confirmed diagnosis of ASMD that received olipudase alfa for at least 12 months were recruited in early 2022 through national patient organizations to participate in a global online questionnaire followed by semi-structured interviews. Ten parents of patients with ASMD who utilized olipudase alfa as an experimental therapy for pediatric patients participated in the study. Quantitative analysis of the results was undertaken and interview transcripts were analyzed using an inductive thematic approach.
Results:
Five themes emerged from analysis: (1) ASMD is a systemic disease with a wide array of manifestations that significantly impact QoL. (2) Olipudase alfa was associated with improvements in all non-neurologic manifestations of ASMD. (3) Participants perceived the risk associated with olipudase alfa to be low and the benefits to greatly outweigh any risk or burden. (4) Participants reported an unmet need to treat the neurologic manifestations of the disease despite the benefits of olipudase alfa in the management of non-neurological symptoms. (5) Participants felt all patients with ASMD need access to olipudase alfa based on the life-changing experience they perceived.
Conclusions:
These findings highlight the sustained positive impact olipudase alfa had in many domains that are deemed important to patients and families living with ASMD and outline the significant unmet need for patients and families living with ASMD.
Leaf phenotypic plasticity and integration balance plant adaptation to water table decline: a mesocosm experiment
Authors: Yang Jun , Gao Yongheng , Zhao Chuan , Chen Huai
Published: July 2023

Functional trait-based approaches have been widely used to explore the relationship between plants and their surroundings. Yet, whether phenotypic plasticity and phenotypic integration are differently functional coordination to enhance plant adaptation to declining water levels is still lacking in empirical knowledge. We conducted a mesocosm experiment in an alpine wetland with two dominant plants, Carex muliensis (hygrophytes) and Pedicularis longiflora var. tubiformis (mesophytes), exposed to four water table gradients (WT10, WT0, WT-20 and WT-50, representing the water table at 10 cm, 0 cm, -20 cm and -50 cm from the surface). We measured leaf traits related to resource use strategies, and the relationship between leaf phenotypic plasticity and integration. We found that hygrophytes shifted their leaf traits towards resource-conserving strategies, such as increasing leaf thickness and decreasing leaf area and specific leaf area, under water table decline. In contrast, mesophytes shifted their leaf traits towards resource-acquisition strategies, enhancing their competitiveness and fitness at low water levels. We also found a negative correlation between leaf phenotypic plasticity and integration in both plant species, suggesting a trade-off between them. which was attributed to the fact that wetland plants may prioritize traits that reduce water loss (e.g. larger leaf thickness), resulting in lower integration with other traits (photosynthetic and nutrient use related traits). We conclude that, water table decline alters plant leaf resource use strategies and that the balance between leaf phenotypic plasticity and integration contributes to plant adaptation to water table decline. This study improves our understanding of the role of leaf phenotypic plasticity and integration in plant adaptation in the context of declining water levels in wetlands will help predict the future structure and composition of alpine wetland ecosystems.

Published: July 2023

As global climate and environmental issues continue to increase, Green Gross Domestic Product (GGDP)
has become a more suitable indicator of economic health and development than Gross Domestic Product
(GDP). This paper proposes a new climate-environment cost-based GGDP model in macro form, using
shadow price that is more economically sound than existing GGDP models. We also introduce a new
method called relation chain analysis to export the GGDP model to micro form. Our mathematical
analysis predicts a positive impact of using our model on the global economy and climate.
Attributes of errors, facilitators, and barriers related to rate control of IV medications: A scoping review
Authors: Park Jeongok , You Sang Bin , Ryu Gi Wook , Kim Youngkyung
Published: July 2023

Background
Intravenous (IV) medication is commonly administered and closely associated with patient safety. Although nurses dedicate considerable time and effort to rate control of IV medications, many medication errors have been linked to the wrong rate of IV medication. Further, there is a lack of comprehensive studies examining the literature on rate control of IV medications. This study aimed to identify the attributes of errors, facilitators, and barriers related to rate control of IV medications by summarizing and synthesizing the existing literature.
Methods
This scoping review was conducted using the framework proposed by Arksey and O'Malley and Preferred Reporting Items for Systematic Reviews and Meta-Analyses Scoping Review extension. Overall, four databases— PubMed, Web of Science, EMBASE, and CINAHL—were employed to search for studies published in English before January 2023. We also manually searched reference lists, related journals, and Google Scholar.
Results
A total of 1,211 studies were retrieved from the database searches and 23 studies were identified from manual searches and Google Scholar searches, after which 22 studies were selected for the analysis. Among the nine experimental studies, two interventions were effective in decreasing errors related to rate control of IV medications. One of them was prospective, continuous incident reporting followed by the implementation of prevention strategies, and the other encompassed six interventions to mitigate interruptions in medication verification and administration. Facilitators and barriers related to rate control of IV medications were classified as human, design, and system-related contributing factors. The sub-categories of human factors were classified as knowledge deficit, performance deficit, and incorrect dosage or infusion rate. The sub-category of design factor was device. The system-related contributing factors were classified as frequent interruptions and distractions, training, assignment or placement of healthcare providers or inexperienced personnel, policies and procedures, and communication systems between healthcare practitioners.
Conclusions
Further research is needed to develop effective interventions to improve IV rate control. Considering the rapid growth of technology in medical settings, interventions and policy changes regarding education and the work environment are necessary.

Published: July 2023

Rock types are the reservoir's most essential properties and show special facies with a defined range of porosity and permeability. This study used the fuzzy c-means clustering technique to identify rock types in 280 core samples from one of the wells drilled in the Asmari reservoir in the Mansouri field, SW Iran. Four hydraulic flow units were determined for studied data after classifying the flow zone index with histogram analysis, normal probability analysis, and the sum of square error methods. Then the two methods of flow zone index and fuzzy c-means clustering were used to determine the rock types in given wells according to the results obtained from the implementation of these two methods in-depth, and continuity index acts, the fuzzy c-means methods with continuity number 3.12 compared to flow zone index with continuity number 2.77 shows more continuity in depth. The relationship between porosity and permeability improved using hydraulic flow unit techniques significantly. In this study, the correlation coefficient between porosity and permeability improves and increases in each hydraulic flow unit using the flow zone index method. So that in the general case, all samples increased from 0.55 to 0.81 in the first hydraulic flow unit and finally 0.94 in the fourth hydraulic flow unit. The samples were characterized by similar flow properties in a hydraulic flow unit. In comparison, the correlation coefficient is obtained less than the general case in the fuzzy c-means method in all hydraulic flow units.
Tunable Parity-Time Symmetry Vortex Laser from Phase Change Material Based Microcavity
Authors: Cao Tun , Su Ying , Fan Hongji
Published: July 2023

Traditional light sources cannot emit the electromagnetic (EM) field with orbital angular momentum (OAM), limiting their applications in modern optics. The recent development of the OAM laser, mainly based on micro- and nanostructures, can satisfy the increasing requirements for on-chip photonics and information capacities. Nevertheless, the static nature of constitutive parameters of photonics structure inherently forbids the attainment of a dynamically tunable OAM laser. Here, we propose a tunable vortex lasing from a micro-ring cavity integrated by a phase change material, Ge2Sb2Te5 (GST225). By modulating the complex refractive index to create an exceptional point (EP) to break the degeneracy of oppositely oriented whispering gallery modes, the micro-laser working at EP can impart an artificial angular momentum, thus emitting vortex beams with well-defined OAM. The grating scatter on the edge of the micro-ring can offer efficient vertical radiation. We find that the vortex laser wavelength from the GST225/InGaAsP dual-layered micro-ring cavity can be dynamically tuned by switching the state of GST225 between amorphous and crystalline while fixing the micro-ring geometry. An electric-thermal model is built to show a tuning range of operating wavelength (EP) from 1544.5 to 1565.9 nm in ~ 25 ns. Our exploration of high-speed tunable PT-symmetry vortex laser opens the door to the next generation of integrated optoelectronic devices for optical computing and communications in both classical and quantum regions.

Published: July 2023

Climate change stabilization at 1.5°C to 2°C requires a shift in paradigm of industries to transition to low carbon industries. The way forward to decarbonize industries is green manufacturing, as the environmental facet of manufacturing has often been compromised for the sake of economic gains. In order to implicate green manufacturing, it is incumbent upon manufacturing facilities to introduce such measures which ensure that carbon footprint and environmentally detrimental emissions are minimized. In this context, Life-cycle Assessment (LCA) is an excellent tool to record, analyze and critically review the environmental impact of a process. In order to investigate the environmental hotspots, the authors have performed LCA of an auto-parts manufacturing industry in Pakistan by using a unique gate-to-gate approach. ReCiPe Midpoint (H) impact assessment method was utilized to investigate the effects of manufacturing and transportation related emissions of the monthly produce on climate change, fossil depletion, ionizing radiation and human toxicity. Furthermore, the authors discuss three scenarios in results, which include current state, optimized future state and an energy mix involving hydropower and photovoltaic generation. The results helped in developing a comprehensive framework for green manufacturing which suggests that the prerequisite of a green manufacturing process is an optimized process flow, which significantly reduces the environmentally detrimental emissions up to 24%. Moreover, the use of photovoltaic cells results in 54% reduction, thus indicating that conventional hydropower systems in developing countries should be mixed with solar power to reduce the environmental burden. A detailed green manufacturing framework based on LCA is proposed by the authors to enhance the functionality and to improvise the carbon burden of the manufacturing sector of Pakistan.

Authors: Fu Xiaokui , Yan Xiaoling , Liu Yanqiu
Published: July 2023

Objective: To compare the value of ECG markers such as QT interval, Tp-e interval and index of cardiac electrophysiological balance (iCEB) in evaluating the effect of sevoflurane on cardiac electrophysiology.
Methods: Sixty patients undergoing elective gynecological surgery were randomly divided into group S1, group S2 and group S3, 20 cases in each group. Patients were received 10ml/kg of hydroxyethyl starch, 0.1mg/kg of midazolam, 0.1 mg/kg of vecuronium, 3μg/kg of fentanyl and 0.3mg/kg of etomidate intravenously. Mechanical ventilation was performed after endotracheal intubation. Sevoflurane concentration was maintained at 0.6 MAC, 1.3 MAC and 2.0 MAC in group S1, group S2 and group S3 respectively. The QT interval, QRS interval and Tp-e interval were measured before anesthesia induction (T1), 5 minutes after tracheal intubation (T2), and 20 minutes after rising to the set concentration of sevoflurane (T3). The QTc interval, Tp-e/QT ratio and iCEB were measured and calculated. MAP and HR were recorded at the same time.
Results Compared with T1-2, MAP and HR decreased at T3 in S1-3 group (P < 0.05); Compared with T1, iCEB increased at T2-3 in S1-3 groups, QTc interval prolonged at T3 in S1-3 groups (P < 0.05). Compared with T2, iCEB increased at T3 in S1-3 groups. Compared with S1 group , the Tp-e Shortened, iCEB increased in S2-3 groups . Compared with S2 group, iCEB decreased in S3 group at T3.
Conclusion: iCEB is more sensitive and objective, and can better predict the risk of arrhythmia. iCEB can be used as the preferred index to evaluate the electrophysiological effects by anesthetics in clinic.

Published: July 2023

Reinforced Concrete (RC) technology is moving towards new frontiers improving its sustainability and durability throughout innovative materials. In particular, the application of Glass Fiber Reinforced Polymer (GFRP) bars, in lieu of the steel reinforcement, shows excellent performance, especially in aggressive environments However, current international design guides and standards are quite conservative, particularly for the shear reinforcement, and this makes the technology less competitive both in terms of the amount of material used and especially in terms of construction. This research aims to analytically compare and experimentally validate the formulations of some international standards on shear capacity in case of reduced shear reinforcement and when the number of stirrups is less than the minimum recommended by the standards itself. The sample beam tests considered two different flexural GFRP reinforcement ratios to assess their role in shear capacity resulting in different collapse mechanisms: longitudinal GFRP bar rupture and concrete crushing. The experimental results were used to compare the North American ACI, French AFGC, and Italian CNR shear capacity design approaches. Analytical capacity expressions are discussed with some remarks aiming to structural optimization.
Research on 5G Heterogeneous Ultra Dense network selection algorithm based on Dueling- DDQN
Authors: XIE JIANLI , ZHU BINHAN , Li Cuiran
Published: July 2023

In the 5G Heterogeneous Ultra Dense Network environment, due to the dense deployment of the network and the diversity of user service types, a more flexible network selection algorithm is required to reduce the network blocking rate and improve the user’s quality of service (QoS). Considering the QoS requirements and preferences of the users, a network selection algorithm based on Dueling-DDQN is proposed by using deep reinforcement learning, which defines the state, action space and reward function of the different services to maximize the cumulative reward value of the network selection algorithm. The simulation results show that compared with other algorithms, the proposed algorithm can effectively reduce the network blocking rate while reducing the switching times.

Authors: Samejima Mai , Nakashima Mitsuko , Shibasaki Jun , Saitsu Hirotomo , Kato Mitsuhiro
Published: July 2023

Background
Neurooculocardiogenitourinary syndrome (NOCGUS), a multisystemic syndrome characterized by motor disorder, intellectual disability, seizures, abnormal brain structure, ocular diseases, and cardiac diseases, has been reported with missense variant of WD repeat-containing protein 37 (WDR37) in humans. This report aimed to identify the cause of neurooculocardiogenitourinary syndrome (NOCGUS) in an affected patient.
Case presentation
We identified a de novo intronic 4-bp deletion of WDR37, c.727 − 27_727-24del, which were predicted to cause abnormal splicing by SpliceAI, in the patient with NOCGUS. Reverse transcription polymerase chain reaction (RT-PCR) revealed intron retention of 63 base pairs before exon 10 in messenger RNA, which was predicted to insert 21 additional aberrant amino acids (p.S242_I243insLCQKKLKISRKCLFWPSLWQQ). The patient had novel phenotypes, anal atresia, and polycystic kidney, in addition to intellectual disability, seizures, cerebellar vermian anomaly, and coloboma, which are typical in NOCGUS. We did not observe motor impairments or cardiovascular anomalies.
Conclusion
This is the first reported case of NOCGUS with the splicing variant of WDR37, which manifests with distinctive but variable features. Our findings may expand a possible phenotypic expression of NOCGUS.

A series of BN/BiOBr heterojunctions was constructed using in situ hydrothermal-precipitation method and was employed to remove the tetracycline molecules in aqueous solution. The rate of photocatalytic degradation efficiency of tetracycline by 0.05BN/BiOBr was ensured to be more excellent than that by BiOBr. The type-II heterojunciton fabricated between BN and BiOBr enforced an internal electron transfer from BiOBr to BN, which inhibited charge recombination. The major reactive species involved in the photocatalysis system were found to be hydroxyl radicals (•OH) and photo-holes (h+), which was verified by the scavenger tests. 0.05-BN/BiOBr heterojunctions showed remarkable reusability and still could degrade 89.25% of tetracycline after four consecutive cycles. According to the characterization and experimental results, a plausible enhanced photocatalytic mechanism was put forward. This work provided the guidance for rational designing heterojunctions with remarkable performance towards antibiotics elimination from wastewater.

Performance monitoring (PM) is a vital component of adaptive behavior and known to be influenced by motivation. We examined effects of potential gain (PG) and loss avoidance (LA) on neural correlates of PM at different processing stages, using a task with trial-based changes in motivational context. Findings suggest more attention is allocated to the PG context, with higher amplitudes for respective correlates of stimulus and feedback processing. The PG context favored rapid responses, while the LA context emphasized accurate responses. Lower response thresholds in the PG context after correct responses derived from a drift-diffusion model also indicate a more approach-oriented response style in the PG context. This cognitive shift is mirrored in neural correlates: negative feedback in the PG context elicited a higher feedback-related negativity (FRN) and higher theta power, whereas positive feedback in the LA context elicited higher P3a and P3b amplitudes, as well as higher theta power. There was no effect of motivational context on response-locked brain activity. Given the similar frequency of negative feedback in both contexts, the elevated FRN and theta power in PG trials cannot be attributed to variations in reward prediction error. The observed variations in the FRN indicate that the effect of outcome valence is modulated by motivational salience.

The authors have been studying the system-scientific modeling of the inpatient flow in an acute-care hospital using the recorded order log data for the movement of patients over a finite observation period. We have thus far published the study results for the patient flows of obstetric and neonatal patients in a hospital. The order log in the University of Tsukuba Hospital during the two fiscal years 2010-2011 was used as a data source.
In the present study, we deal with pediatric patients who are transferred over several wards from their admission until their discharge. We calculate the number of admissions, ward transfers, and discharges during the two years of observation. Special attention is paid to the numbers of patients who are hospitalized before and after the finite observation periods. We consider the total number of days on which patients stay in each ward over the observation period, which is called the patient-days (PD) as a measure of clinical load brought by patients on the hospital. We count the numbers of patients who arrive to, depart from, and stay in each ward over the observation period and show that these numbers satisfy the conservation law for the patient flow in a hospital. We also confirm an identity relation among the mean number of patients staying in each ward per day, mean number of patients who arrive to that ward per day, and mean number of days a patient stays in that ward, called the mean length-of-stay (LoS), which may be thought of as a discrete-time, finite-horizon version of Little's law in queueing theory. We propose a patient residence chart to visualize the movement of each patient during their hospitalization. We present a method to classify the paths of patients, i.e., a sequence of pairs (ward number, length-of-stay on that ward), from which we calculate a variety of measures of patient movement.

Heart rate variability (HRV) analysis is often used to estimate human health and fitness status. More specifically, a range of parameters that express the variability in beat-to-beat intervals are calculated from electrocardiogram beat detections. Since beat detection may yield erroneous interval data, these errors travel through the processing chain and may result in misleading parameter values that can lead to incorrect conclusions. In this study, we utilized Monte Carlo simulation on real data, Kolmogorov-Smirnov tests and Bland-Altman analysis to carry out extensive analysis of the noise sensitivity of different HRV parameters. The used noise models consider Gaussian and student-t distributed noise. As a result we observed that commonly used HRV parameters (e.g. pNN50 and LF/HF ratio) are especially sensitive to noise and that all parameters show biases to some extent. We conclude that researchers should be careful when reporting different HRV parameters, consider the distributions in addition to mean values, and consider reference data if applicable. The analysis of HRV parameter sensitivity to noise and resulting biases presented in this work generalizes over a wide population and can serve as a reference and thus provide a basis for the decision about which HRV parameters to choose under similar conditions.

Estuarine areas usually suffer significant trace element contamination effects, resulting in significant environmental risks. This is the case of the Paranaguá Estuarine System (PES), located in Southern Brazil, home to one of the largest ports in Latin America and it still boasts of a remarkable biodiversity surrounding by threatened mangrove areas. In this context, this study aimed to assess the quality of sediments concerning metals and metalloid As contamination and comparison to sediment contamination guidelines. In addition, biochemical normalization factors were applied to find out if the sources of the investigated elements were natural or anthropogenic. In 2018, 38 surface sediment samples were sampled seasonally from different PES areas to the determination to metals, metalloid As, and geochemical characteristics. Higher element values analyzed were detected close to the cities of Antonina and Paranaguá and near river mouths, potentially associated with port activities and anthropogenic throughout the surrounding drainage basins. The results revealed concentrations above the Threshold Effect Level (TEL) for Cr, Cu, and metalloid As. The Principal Component Analysis of the analyzed variables showed a strong interaction involving metals/metalloids, organic matter, nutrients, total organic carbon and the fine fraction of sediments. Metals and metalloid As concentrations were lower than in other tropical estuaries, which may indicate water column desorption or aquatic organism absorption, potentially associated to physicochemical water variations or sediment remobilization and resuspension due to dredging activities. The applied geochemical indices indicate low to moderate PES sediment contamination, although some areas presented high values, leading to ecological concerns.

Background
Patient satisfaction is currently a recognized measure of the effectiveness and quality of the healthcare system. It serves as an essential tool in raising the standard of care. The objective of this study was to examine patients' satisfaction with the quality of nursing care provided.
Methods
A cross-sectional hospital-based study was conducted, involving 400 patients selected through a systematic random sampling method, meeting the selection criteria. Data were collected using the "Patient Satisfaction with Nursing Care Quality Questionnaire," comprising a total of 19 items. The collected data were then analyzed and interpreted using descriptive and inferential statistics. Data was analyzed using STATA software V17.
Results
The study revealed that the highest level of satisfaction (mean 2.31, SD 1.33) was observed in the coordination of care after discharge, specifically nurses' efforts to cater to patients' needs after they left the hospital. The lowest satisfaction level was related to privacy, with provisions for patients' privacy by nurses scoring 3.9 (SD 1.00). Overall, questionnaire scores ranged from 2.31 to 3.9, with an average score of 3.26 (SD 0.64).
Conclusion
Overall, patients expressed general satisfaction with the inpatient nursing care they received, and their perceived needs and care expectations from nurses significantly influenced their satisfaction levels. Therefore, we recommend that hospital administrators regularly assess patient satisfaction levels and provide specialized on-the-job training to nurses to enhance their ability to meet patients' needs and increase their overall satisfaction.
