In the present article, we define the concept of isoclinism for n-Hom-Lie algebras and investigate some of its properties. Also, we introduce the factor sets on n-Hom-Lie algebras. As a result, it is shown that the equivalency between isoclinism and isomorphism of two finite- dimensional n-Hom-Lie algebras just depends on whether one of them be regular.

The present study was conducted to predict risky sexual behaviors of female high school students based on executive functions and emotion regulation. The present research method was descriptive-correlational. The statistical population included all female secondary school students of Babol City in the academic year of 2022-2023, from which 200 people were selected as a sample using available and non-random sampling methods. Data were collected using Zarei et al.'s Risky Sexual Behavior Questionnaire (RSBQ, 2009), Gioia et al.'s Behavioral Rating List Of Executive Functions (BRIEF, 2000), and Garnefski & Kraaij's Cognitive Emotion Regulation Questionnaire (CERQ, 2006). Multiple regression analysis was used to analyze the data. The findings of the research showed that executive functions and emotion regulation were able to predict sexual risky behaviors (p<0.05) and in total explain 49% of the variance of sexual risky behaviors. Therefore, it can be concluded that executive functions and emotion regulation play a significant role in predicting risky sexual behaviors and the need to pay attention to these factors seems necessary to reduce risky sexual behaviors in students.

Based upon WHO (World Health Organization) Coronavirus Dashboard more than 5 million deaths worldwide have been attributed to the COVID-19 (Coronavirus Disease 2019) caused by the SARS-Cov-2 virus (Severe Acute Respiratory Syndrome Coronavirus) till November 2021. The annual flu vaccination has raised many questions about the vaccine's effects on Covid-19 outcomes. Several possible mechanisms including cross-reactivity and cross-protection have been reported to be responsible for the potential protective effect of the flu vaccine on the COVID-19 infection. This study was performed to evaluate the possible effect of the influenza vaccine on the disease severity, the mortality rate, and the length of hospitalization in COVID-19 patients. 

The data of 1300 patients were recorded from May 2020 to October 2020. Patients with a previous history of COVID-19, patients under 18 years old, and patients who did not have accurate information about their influenza vaccination history were excluded. 498 hospitalized unvaccinated COVID-19 patients with typical clinical manifestations and a positive PCR (Polymerase Chain Reaction) test for COVID-19 were included in this observational, cross-sectional study. The participants were divided into two groups (vaccinated and unvaccinated) based on the history of influenza vaccination at the time of admission.

The length of hospital stay was lower in the vaccinated compared to the unvaccinated group (p < 0.05). However, there was no significant difference between the mortality rate, the need for ICU (Intensive Care Unit) admission, and the severity of the disease between the two groups (p> 0.05).

Since the patients studied in this article did not receive any of the Covid-19 vaccines; Therefore, the effect of influenza vaccination on the clinical course of Covid-19 can be evaluated using the results of this study. A longer length of hospital stay was observed in the unvaccinated patients in our study, which may suggest the possible protective effect of the influenza vaccine against COVID-19.
