The current research aims to identify the level of extension of the sense of self and the cognitive style (complexity - simplification) among university students, as well as the significance of the difference according to gender (males - females), as well as the correlation between the two variables, and in order to verify this, the researcher has constructed The measure of the extension of the sense of self based on the theory of Alport 1961, as the number of its final paragraphs reached (28) paragraphs, and the cognitive style scale (complexity - simplification) prepared by (Abdullah 2017) was adopted, as the scale consisted of (32) paragraphs in its final form. To verify their psychometric properties, and the two tools were applied to

Lack of awareness of food for mothers of children Riyadh of the factors affecting the nutritional status of the child, and that child health is closely linked to the nature of the child as much as the quality and quantity of food, so current research aims to identify:

- Food awareness among mothers of children Riyadh.

- Statistically significant differences in nutritional awareness depending on the collection of the mother.

- Statistically significant differences in nutritional awareness depending on the age of the mother.

- With statistical significance in food awareness of the mother differences being an employee or non-employee.

So researchers randomly chosen sample of (200) or from mothers chil

Abstract

       The grey system model GM(1,1) is the model of the prediction of the time series and the basis of the grey theory. This research presents the methods for estimating parameters of the grey model GM(1,1) is the accumulative method (ACC), the exponential method (EXP), modified exponential method (Mod EXP) and the Particle Swarm Optimization method (PSO). These methods were compared based on the Mean square error (MSE) and the Mean Absolute percentage error (MAPE) as a basis comparator and the simulation method was adopted for the best of the four methods, The best method was obtained and then applied to real data. This data represents the consumption rate of two types of oils a he
