Authors: Ramirez Del Castillo Miguel Daniel , Chavez-Romero Zaida Brenida , Alvarado-Silva Carlos Alexis , Rosario De Oliveira Geraldo Cesar , Gaytan-Reyna Sassy Emperatriz 
Published: September 2023

The aim of this research is to identify the factors impacting customer satisfaction, focusing on customer perceptions within one of the country's most prominent delivery companies, specifically centered in the city of Chiclayo, Peru. The study utilizes the SERVPERF model, which gauges customer perceptions across five dimensions: reliability, responsiveness, security, empathy, and tangibility. Interviews were conducted with the manager and several delivery drivers in the city to comprehend operational processes. To gather unbiased customer opinions, a survey was administered to 196 customers. The results indicate that customers assess the company's service quality as average. Despite the elevated demand, customers display a relatively low level of contentment with the service provided. Furthermore, the research explores the extent of customer satisfaction. Through Pearson's correlation analysis, it was ascertained that the dimensions exerting influence on satisfaction encompass reliability, security, and empathy. The study also establishes that the degree of satisfaction averages out and is intrinsically tied to the quality of service.

The Comparative of Arbitration Performance and Public Court on Settlement of Civil Disputes in Indonesia
Authors: Abdullah Iqbal Alan 
Published: September 2023

The purpose of this study is to describe the comparison of dispute resolution mechanisms by arbitration and dispute resolution through general courts. This study uses normative juridical, referring to legal norms which include laws and regulations, court decisions and applicable legal rules. Furthermore, this research will answer legal issues regarding dispute resolution through arbitration. Normative legal research is "legal research conducted by examining literature (secondary data). The results of the study indicate that there are two choices of arbitral institutions to resolve disputes, namely arbitration and general courts. Comparison of dispute resolution mechanisms between arbitration and institutional arbitration is that arbitration has the freedom of the parties to determine the arbitrator, guarantees the confidentiality of the parties because dispute resolution is carried out in private, the parties can determine the place of arbitration, choice of law in dispute resolution, and the dispute resolution process is faster, namely can be completed in no more than 180 days. While settlement through a general court requires a relatively long time, is open to the public, and is confrontational in nature, all decisions are final and binding. However, for arbitration, the recognition and implementation of the decision must still be registered with the district court. Weaknesses of arbitration are the emergence of suspicion of each party about the closeness of the arbitrator, given the current sophistication of technology, so that the number of dispute resolution through arbitration in Indonesia is very small. Society prefers litigation over non-litigation.

Various events can affect a country's exchange rate. In the period between 2020 and 2021, Peru experienced the severe effects of the COVID-19 pandemic, as well as political instability. This article has two objectives: first, to explore what was the average monthly exchange rate (sale) in Peru between January 2020 and December 2021; second, to determine if there is any significant trend in the data shown for that period. The research presented a quantitative approach, descriptive level, non-experimental design and retrospective cross-sectional cut. The technique was documentary review and the instrument was the registration form. The data provided by the Central Reserve Bank of Peru (Monthly average bank exchange rate -sale-) were explored. As a result, it was found that the lowest value was recorded in January 2020 (S/3,329), while the highest value was recorded in September 2021 (S/4,111). In addition, the result of the Mann-Kendall trend statistical test resulted in a p. value of < 0.0001, thus there is a significant trend in the average monthly exchange rate (sale) in Peru between January 2020 and December 2021.

Published: September 2023

Using the 3D printing method as an engineering teaching tool has been intensifying and implemented throughout all the courses of the engineering career and even in research departments, this means that it not only fulfills the functions for those that were originally designed (manufacturing of parts) but as a support for the acquisition of other important skills in future engineers. The research has a quantitative approach, experimental design with a control and experimental group of 35 and 37 students respectively. For its execution, a pre-test and post-test have been used as instruments, which were applied to students of a Technical Drawing subject of the career of Mechanical-Electrical Engineering. The findings reveal that the proposed teaching strategy using 3D printed elements significantly improves the level of abstraction for the generation of orthogonal projections. After the experiment, the control group showed an improvement in average grades of 20.3%, this indicates that the application of traditional teaching improves the level of abstraction. In the case of the experimental group, a higher average of the grades was obtained with a 30.8% improvement, which means that the students felt more comfortable with the proposed teaching strategy. On the other hand, the proposal was well received by the students who participated in the session, as they stated through the satisfaction survey that they were 90% between satisfied and very satisfied.

In this paper, the problem of bending of a multilayered rod by transverse loads in the presence of zones of elastic and nonlinear-inelastic deformation is considered, the retios are obtained to determine the boundary between the elastic and nonlinear-inelastic areas of deformation of the rod. Various cases of the position of the specified boundary between areas are considered, depending on external loads. The expressions for ultimate loads are given for each of the characteristic cases of the location of these boundaries: the first (deformation reaches the limit elastic value) and the second (deformation reaches the value of pre-fracture deformation).

Published: September 2023

The positive effects of plants, including stinging nettle (Urtica dioica L.) were reported by numerous researchers (1) as well as changes in the chemical composition of the plant due to heavy metal pollution (2, 3). This study aimed to compare the changes in body wight, total leukocyte numbers (TL) and delayed type hypersensitivity (DTH) in 28 days old chickens (n=12/group) injected subcutaneously twice (days 0 and 7), with 0.5 ml of alcoholic nettle extracts harvested from both unpolluted (group III) and polluted areas (group IV), against untreated (group I) and 700 alcohol treated (group II) controls. Blood was sampled three times, on days 0, 7 and 14, while the wattle test to a homologous lymphocyte suspension was performed on day 14 of the experiment.
There were no significant differences in weight gain/period between groups III (0.979 kg) and IV (0.967kg), against each other and controls (0.991 kg-group II and 1.029 kg - group I, respectively). As opposed to the slight changes of the TL in control groups, there was a constant increase in group III (from 15,400±3,421/mm3 to 17,125±4,231/mm3) and a decrease in group IV (17,611.1±2,401/mm3 to 17,166.7±2,522/mm3).
The wattle test results after 48 h were similar in groups I, II and IV, the differences ranging between 0.23 and 0.28 mm, while the unpolluted nettle extract diminished the DTH to a difference of 0.07 mm.
The polluted nettle extract induced the lowest weight gain and TL numbers, and increased the wattle reactivity when compared to the unpolluted one.
A New Insight into the Linear Theory of Magnetoacoustic Waves in the Homogeneous Flux Tubes with an Abrupt Boundary
Authors: Yelagandula Naga Varun 
Published: September 2023

Abstract
An important and interesting issue is brought to notice in the standard linear theory of the magnetoacoustic waves in the homogeneous magnetic flux tubes with an abrupt magnetic boundary, which are representative of the coronal, chromospheric, and photospheric loops of the solar atmosphere. It is shown that the dispersion relation given for the magnetoacoustic waves of such flux tubes by the linear standard theory is generally inapplicable because it does not take into account the electrodynamic boundary condition and the applicability is only restricted to the case β = 0, where β is the usual plasma parameter given by the ratio of the thermodynamic gas pressure to the magnetic pressure. This issue is then addressed, which gives us new insight into the standard linear theory of such modes, and a new dispersion relation is obtained, which is generally applicable i.e., for all β and would reduce to the earlier expression as a special case for β = 0. Finally a comparison is drawn between the dispersion curves described by the newly derived dispersion relation and its previous counterpart.
Toward an Optimal Reconstruction of the Shear Field with PDF-folding
Authors: Wang Haoran , Zhang Jun , Li Hekun , Liu Cong 
Published: September 2023

Abstract
Weak lensing provides a direct way of mapping the density distribution in the Universe. To reconstruct the density field from the shear catalog, an important step is to build the shear field from the shear catalog, which can be quite nontrivial due to the inhomogeneity of the background galaxy distribution and the shape noise. We propose the PDF-folding method as a statistically optimal way of reconstructing the shear field. It is an extention of the PDF-SYM method, which was previously designed for optimizing the stacked shear signal as well as the shear-shear correlation for the Fourier_Quad shear estimators. PDF-folding does not require smoothing kernels as in traditional methods, therefore it suffers less information loss on small scales and avoids possible biases due to the spatial variation in the shear on the scale of the kernel. We show with analytic reasoning as well as numerical examples that the new method can reach the optimal signal-to-noise ratio on the reconstructed shear map under general observing conditions, i.e., with inhomogeneous background densities or masks. We also show the performance of the new method on real data around foreground galaxy clusters.
Concerning the Verity of the MMRD Relation for Novae
Authors: Shafter Allen W. , Clark J. Grace , Hornoch Kamil 
Published: September 2023

Abstract
It has long been claimed that novae reaching the highest luminosity at the peak of their eruptions appear to fade the fastest from maximum light. The relationship between peak brightness and fade rate is known as the Maximum-Magnitude, Rate-of-Decline (MMRD) relation. Lightcurve parameters for the most recent sample of M31 recurrent novae are presented and used to buttress the case that the observed MMRD relation can be explained as a consequence of observational selection effects coupled with expectations from standard nova models.
Patient Safety Error Reporting Education for Undergraduate Nursing Students: A Scoping Review
Authors: Song Mi Ok , Yun So Young , Jang Aeri 
Published: September 2023

Background:
Patient safety error reporting is essential for learning and preventing errors, and nursing students should develop error reporting capabilities through error reporting education. This study examined undergraduate error reporting education to identify a sustainable development direction.

Method:
A systematic literature search of three major scientific databases identified nine articles that met the inclusion criteria. Data on error reporting education features and future error reporting education challenges were extracted.

Results:
Eight studies presented content and error levels according to World Health Organization incident type. Simulations and error reporting systems were used frequently as teaching-learning methods. Although most programs involved Level 3 of Kirkpatrick's levels in error reporting education, programs involving innovative thinking for sustainable error reporting education development are lacking.

Conclusion:

For more effective error reporting education, active teaching methods such as virtual reality simulations and planning, applying, and evaluating methods for long-term direct clinical error reporting are required.

Published: September 2023

Growing evidence shows that COVID-19 is associated with an increase in Tako-Tsubo syndrome (TTS) incidence. We collected data from patients hospitalized in our multidisciplinary COVID-19 department who had a diagnosis of TTS during the second and third wave of the pandemic in Italy. We reported four cases of TTS associated with COVID-19. No patient had any classical trigger for TTS except for COVID-19. Mean age was 72 years (67-81) and all patients had a SARS-CoV-2-related interstitial pneumonia confirmed by computed tomography. Typical apical ballooning and transitory reduction in left ventricle (LV) systolic function with a complete recovery before discharge were observed in all patients. The mean LV ejection fraction (LVEF) at TTS onset was 42% (40-48%). ECG showed ST-segment elevation in two cases, while an evolution with negative T waves and QTc prolongation was observed in all patients. Three patients underwent coronary angiography. Two patients had Alzheimer’s disease. The time interval from hospital admission to TTS onset was 4 (2-6) days, and the time interval from COVID-19 symptom onset to TTS diagnosis was 10 (8-12) days. COVID-19 may be a trigger for TTS, though TTS pathophysiology in COVID-19 patients remains unclear, likely due to its multifactorial nature.

Authors: Saveri Katragadda , Rachala Madhukar R. , Dasari Arun K. , Mallikarjun Vankre , Nikhil Sakam , Gurram Dhana P. 
Published: September 2023

OBJECTIVES:
This study aimed to compare and evaluate the effect of three staining solutions on the color stability of three different brands of esthetic archwires using a spectrophotometer and also to compare the fluorescence of esthetic archwires with extracted human teeth.

MATERIALS AND METHODS:
A total of 84 nickel–titanium (NiTi)-coated esthetic archwires with the same cross section and size (0.016 × 0.022″) were included. All samples were divided into four groups of 21 each, that is, group 1: artificial saliva (AS), group 2: coffee (C) solution, group 3: turmeric (T) solution, and group 4: chlorhexidine (CH) mouth rinse; each group was subdivided into three subgroups of seven each (Opal Classic (OC), Libral Rabbit Force (LRF), and Ortho Organizers (OO)). The baseline value (T0) was measured before immersion in the staining solution and then immersed in the staining solution for 21 days. The color measurements were recorded at different time intervals on the 7th, 14th, and 21st days using a spectrophotometer. The fluorescence of archwires is tested in a dark atmosphere using a fluorescent black lamp. The data obtained were analyzed using descriptive statistics, analysis of variance (ANOVA), and post hoc Bonferroni test.

RESULTS:
A significant amount of color change in all three brands of archwires from day 0 to day 21 (p < 0.005) was observed, except for OC in the CH mouth rinse group (p = 0.230). The fluorescence of OO matches with the natural teeth.

CONCLUSION:
LRF showed the highest overall color change followed by OO and OC. Turmeric is the most chromogenic agent, followed by Coffee and CH mouth rinse.

Published: September 2023

Infection control is essential to protect both the doctor and the patient by preventing the spread of infectious diseases. There is no exception in the field of dentistry, particularly in orthodontics, where numerous appliances are used for a variety of functions and also because the mouth cavity has the highest concentration of bacteria of any body part. Through this systematic review, we aimed to assess the various methods of sterilization employed in an orthodontic setting. Using relevant keywords, reference searches, and citation searches, the databases such as PubMed, MEDLINE, Web of Science, Cochrane, and Scopus were all searched; a total of 206 documents were found, of which 113 were initially selected. The remaining 23 distinct papers were initially made available after 90 publications that were identical to or similar to one another were eliminated. The final selection was made from eight documents that met all inclusion and exclusion requirements. The existing methods of sterilization were found to be competent in dealing with the microorganisms found in a typical orthodontic setting. The chemical method of sterilization was the norm in most of the studies that we assessed, with glutaraldehyde and peracetic acid (PAA) being the most commonly employed compounds for disinfection.
