The aim of this article was to investigate the relationship between service quality and customer satisfaction in the educational services provided by INTERPASS S.A.C. in Lima in 2021. The study used a survey technique and a questionnaire as data collection tool, with a sample of 325 students selected through random sampling. To test the hypothesis, the study employed Chi-square statistics and Spearman's correlation test. The results showed a statistically significant association between service quality and customer satisfaction. The statistical analysis confirmed the study’s main hypothesis that there is a positive impact of service quality on customer satisfaction in the company studied. This was evidenced by a high Chi-square value of 374.952 and a strong Spearman correlation of 0.806, indicating a significant relationship between the two variables.

Introduction: Peritonitis is an inflammatory process of multiple etiologies that can compromise the patient's life, so it is necessary to understand the risk factors that are associated with poor clinical evolution. Objectives: To determine the factors associated with poor clinical evolution in adult patients hospitalized for peritonitis in the Emergency Hospital "José Casimiro Ulloa, 2012 - 2016". Methods: Analytical, retrospective study, of type cases and controls. The universe population of the cases will be conformed by all the patients with bad evolution (patients with a hospital stay greater than 9 days). The universe population for the control group consisted of patients with peritonitis with favorable evolution (patients with a hospital stay of less than 9 days) hospitalized for peritonitis. The descriptive and analytical analysis was done with chi square and logistic regression...

Objective: To describe the conditions and characteristics of the tracheostomy procedure in a tertiary health care unit and analyze its association with the recorded outcome. Materials and methods: A retrospective, observational and descriptive study that included patients operated in the Otorhinolaryngology Unit of the Northwest National Medical Center, Sonora, from August 2014 to August 2015. Fifty-two (52) complete clinical records of consecutive series of cases were reviewed, out of which 57% were men with an average age of 56.2 years old. Descriptive statistics was used to characterize the distribution, and the differences were evaluated by chi-square test and Student’s t-test. Results: Seventy-one percent (71%) of the patients underwent surgery in an operating room and 29% in the ICU. In the latter, more than half of the cases had a tracheostomy (51.92%). Prolonged intubation was ...

Objective: To evaluate the risk factors for dengue with warning signs in patients seen in the emergency department of a Public Hospital located in Trujillo, Perú, during the period from January to October 2023. Materials and methods: A case- control study was conducted at the emergency department of the Hospital Distrital Jerusalén in Trujillo, Perú, between January and October 2023. In the data analysis, chi-square and Fisher tests were used to identify variables associated with warning signs of dengue (p<0.05); subsequently, multivariate logistic regression was performed to calculate the adjusted Odds ratio (ORa) with its respective 95% confidence intervals. Results: We included 92 cases of dengue with warning signs and 184 controls without warning signs. Age, education level, arterial hypertension, obesity and previous infection were significantly associated (p<0.05) to de...

This study evaluates the application of Total Productive Maintenance (TPM) and Lean methodologies in the Peruvian agricultural sector, focusing on asparagus packing operations. To this end, it develops an innovative model with the objective of increasing the productivity of asparagus packing, one of the main problems of the Peruvian agricultural industry. Through the application of an autonomous and preventive maintenance strategy, it seeks to eliminate untimely stops in the asparagus processing line. Meanwhile, with the implementation of standardized work, the aim is to eliminate activities that do not add value and downtime. A pilot project was implemented with a sample of 72.98 kg of processed asparagus, using the processing times of each activity as input data for the validation model, using Kolmogorov- Smirnov and Chi-square statistical tests to define the distributions of the times...

Purpose: The technical feasibility of using Benford's law to assist internal auditors in reviewing the integrity of high-volume data sets is analysed. This study explores whether Benford's distribution applies to the set of numbers represented by the quantity of records (size) that comprise the different tables that make up a state-owned enterprise's (SOE) enterprise resource planning (ERP) relational database. The use of Benford's law streamlines the search for possible abnormalities within the ERP system's data set, increasing the ability of the internal audit functions (IAFs) to detect anomalies within the database. In the SOEs of emerging economies, where groups compete for power and resources, internal auditors are better off employing analytical tests to discharge their duties without getting involved in power struggles. Design/methodology/approach: Records of eight databases of an...

Canine ehrlichiosis is a worldwide well known infectious disease and potentially lethal to dogs and other members of the Canidae family. It is caused by Ehrlichia canis and transmitted by the brown dog tick Rhipicephalus sanguineus. The aim of this work was to carry out a retrospective case-control study in order to evaluate the risk factors associated with the presence of canine ehrlichiosis in dogs that have been patients at the Clinic of Small Animals and at the Clinical Pathology Laboratory of the Veterinary Faculty, San Marcos University, Lima. For this purpose, cases (dogs with ehrlichiosis: n=50) as well as controls (dogs without ehrlichiosis: n=100) from clinical records in the period of 2002-2005 were used. Data was grouped by breed, sex, age, history of tick presence, and home location. Chi square, odds ratio (OR), and logistic regressions were performed. Among the cases, 50% w...
