The research aimed to find the relationship between Internet Vigilance, emotional creativity, and self-sufficiency. The current research sample consisted of (898) male and female students at Damietta University in the faculties of (Specific Education - Education - Physical Education - Applied Arts - Commerce - Science - Engineering - Literature – Computers and information) in the first and fourth academic year, with an average age of 20.09 and a standard deviation of 2.56 in the first university semester of the academic year 2022/2023. With the aim of revealing their levels in the Internet Vigilance variable, the level of the emotional creativity and self-efficacy variables, and the extent of the differences between them due to gender, academic stage, and specialization, and the nature of the relationship between each of the electronic alertness variable, the emotional creativity variable, and self-efficacy among male and female university students. Damietta, in the colleges of (Specific Education - Education - Physical Education - Applied Arts - Commerce - Science - Engineering - Literature - Computers and Information), Regarding the extent to which it is possible to predict each of the variables of emotional creativity and self-efficacy through the dimensions of the Internet Vigilance variable, the researcher here relied on two tools to measure the variable dimensions of Internet Vigilance, the (Reince et al., 2018) scale to measure the trait, and the (Johannes et al., 2020) scale to measure the situation, as the researcher Arabized it, codified it, and verified the extent of its psychometric properties, and two tools to measure the variables of emotional creativity and self-efficacy among male and female students at Damietta University in the faculties of (Specific Education - Education - Physical Education - Applied Arts - Commerce - Sciences - Engineering - Literature - Computers and Information) prepared by the researcher. To identify the results of the research, the following statistical treatments were used: T-test for independent samples, Cronbach's Alpha test, One-Way ANOVA, frequencies, arithmetic means, standard deviations, and correlation analysis. Pearson correlation coefficients, multiple regression analysis, and the bootstrap method to test confidence interval (CI) estimates, using version 23.0 of the statistical program SPSS. The research showed several results, the most important of which are: the existence of a significant correlation between Internet Vigilance and emotional creativity, and that the Internet Vigilance variable predicted emotional creativity, while The results related to self-efficacy showed its mediation in the relationship between each of the variables (Internet Vigilance and emotional creativity).The results also showed that the effect of self-efficacy on Internet Vigilance among university students varies according to the students’ academic stage. The results also showed that there are statistically significant differences in the relationship between self-efficacy and emotional creativity among university students depending on the variable of type (sex), as well as specialization (scientific/ literary).

The current research aims to form a standard to measure the orientation towards life among orphaned adolescents to provide researchers in the field of Mental Health with suitable standards for measuring Orientation towards life among Orphaned adolescents, The researcher has built the scale in the light the results of theoretical frameworks and previous studies that dealt with concept of orientation towards life, and it was reached the final image which consisted of (33) statement, distributed on three basic dimensions (Optimism, Pessimism, Orientation towards future). This scale was applied to a sample of (105) male and female orphan adolescents of residing in residential institutions and those residing among their extended families, of age ranged between 15-18 years, with a mean chronological age of (16.45), and a standard deviation of (0.87). The validity and reliability of the scale were measured to ensure of the psychometric efficiency of the scale, The researcher has followed in measuring the validity several methods, including the validity of the arbitrators, the validity of affirmative construction. As for the credibility of the scale the researcher relied on Alpha Cronbach's method, The half-segmentation method and retest method The scale seemed to has acceptable credibility and validity indications at (0.01). This prove the credibility of the scale factors to measure what it meant to measure. [ABSTRACT FROM AUTHOR]

Results indicate a high relative importance of variable costs, as the average variable costs of manufacturing a ton of ore milk ranged between a minimum of 93.15% of the total manufacturing costs of turkey cheese, and the maximum about 98.94% of the total manufacturing costs of liquid milk.in addition, average fixed costs ranges between a minimum of 1.06% of the total manufacturing costs for liquid milk and the maximum about 6.85% of the total manufacturing costs for turkey cheese. The decrease of relative importance of fixed costs is due to an increase in the size of the maximum operating energy, also the productive unit (laboratory) produces more than one type of milk products, which leads to distribute total fixed costs to these products. The results also indicate that yogurt achieve the highest profit where a ton of raw milk achieves a profit about 6872.71 L.E, Followed by the ice cream, where it achieves a profit about 5721.00 L.E, While turkey cheese achieves the lowest profit at about 821.26 L.E. By studying the added value of different dairy products, it was found that the yogurt ranked the first at 7784.31 L.E, while the added value of turkey cheese reached the lowest value about 2563.51 L.E. Total profit resulting from manufacturing of raw milk to different dairy products reached about 4595.25 L.E. Also, yogurt gets about 1580.72 L.E, with a relative importance is about 34.40% of the total profit, It is followed by an ice cream with about 858.15 L.E, with a relative importance is about 18.67% of the total profit, Then white cheese by about 798.37 L.E, with a relative importance of about 17.37% of the total profit, while the rest of the milk products (liquid milk, cottage cheese, ripe milk and turkey cheese) get about 1358.01 L.E, with a relative importance about 29.55% of the total profit. Total added value resulting from the manufacture of a ton of raw milk into different dairy products were about 5552.07 L.E The yogurt gets about 1790.39 L.E with relative importance about 32.25% of the total added value, followed by the white cheese was about 1063.19 L.E with a relative importance about 19.15 % of the total added value, followed by ice cream was about 952.23 L.E, with a relative importance about 17.15% of the total added value, and the rest of the milk products (liquid milk, cottage cheese, ripe milk and turkey cheese) get about 1746.26 L.E, with a relative importance about 31.45% of the total value added. Therefore, the research recommends that, according to the profitability and the added value of dairy products, Dairy Management must restructure the manufacturing rates of these products by increasing the percentage of the quantities that used from raw milk to manufacture the most profitable products (yogurt, then ice cream, then cottage cheese, then white cheese, then the ripe milk, then the liquid milk and finally the turkey cheese) to maximize its economic returns.
