The focus of this study is to examine the students’ degree of satisfaction towards the academic counseling or guidance services during the preparatory year at Prince Sattam bin Abdulaziz University for the academic year 2020-2021 and report the difference, if any, in the level of this satisfaction based on the difference of the students’ gender. This study used a self-administered survey as an instrument for data collection. The final sample consists of 440 students in Medical and Engineering Colleges. We find that there is a moderate level of satisfaction towards the services of academic guidance offered to the students. In addition, we find that there is a significant difference in the level of satisfaction towards the services of academic guidance by the gender at 5% level. The findings of this study are important for policymakers at the university and college levels. This study suggests that the colleges should increase their academic guidance services offered to students during their studying the preparatory year. Moreover, unifying the level of academic guidance services provided to both male and female sections in a manner to achieve the quality of this service provided to male and female students.

This paper aims at identifying the probability distributions used in controlling the quality of products of industrial companies by examining the degree of the probability distributions' efficient in strengthen the control process that, consequently, would lead companies to cope with the new technologies to overcome the difficulties and problems they counter in controlling the quality of their products. This study used discrete and continuous probability distributions and explained how they can be used in acceptance inspection plans and quality control charts by examining the inputs and outputs of the production process and the production process itself. The results of this study indicated to the use of probability distributions maintains continuous improvement in quality and checks for convergence between inputs and outputs. In addition, the use of probability distributions enhances the efficiency and effectiveness of quality control. The results of this study are of importance to managements in the manufactured companies concerning the significance of using probability distributions to control the quality of products at all stages of production. Moreover, the establishment of periodical training programs specialized in quality control, with a focus on the use of probability distributions.

This research aims to identify one of the methods of statistical quality control, which is represented in the indicators of the Capability Process and explains its importance and how to use it for knowing the extension of the process to fulfill the specifications through several indicators with a statement that through practical application on one of the pharmaceutical products (Paramol Tablets Weights) one of the products of Yemeni Drug Company for Industry and Commerce (YEDCO). Hence, the results showed that the permits of process specifications of the tablet weight are equal to about 5 standard deviations, which is less than the standard practices, which are 8 standard deviations. Therefore, the capacity of the process for tablet weight is Cp<1, which is an undesirable state; because the production process is unable to satisfy the specifications. The CPK indicator shows that the process is decentralized and hence the inability of the process to fulfill the specifications; therefore, the company has to revise the limits of Paramol tablet weights specifications and to expand it as the company adopts numerous pharmacopeias in its operations. It must select the pharmacopeia that gives specifications which can make the process capability indicator and the index of process concentration in their standard state (Cp, Cpk=1.33mg).
