Web application protection is today's most important battleground between the victim, intruder, and web service resource. User authentication tends to be critical when a legitimate user of the web application abruptly ends the contact while the Session is still active, and an unauthorized user chooses the same Session to gain access to the device. For many corporations, risk detection is still a problem. In other cases, it is a usual way of operating that provides the requisite protection to keep the product free of weaknesses. Using various types of software to identify di erent security vulnerabilities assists both developers and organizations in securely launching applications, saving time and money. Di erent combinations of tools have been seen to enhance protection in recent years, but it has not been possible to combine the types of tools available on the market until the writing of this report. This paper aims to clarify vulnerabilities in broken authentication and Session Management. It is worth noting that if the creator practices the preventive techniques outlined in this article, the chances of exploitation being discussed are reduced. This paper revealed that the most powerful ways to exploit the Broken Authentication and Session Management vulnerabilities of the web application in those domains are Session Miscon guration assault and Cracking/ Guessing Weak Passwords. Correspondingly included techniques to defend authentication and the most important is using a robust encryption system, setting password rules, and securing the Session ID.

In the critical review of the book “Ethics of Management” written by Tomas Klikavar (2010), the present article has paid attention to the general approach of the author, the conceptual tools used, and the way of reasoning. According to the author, Management, especially business Management, due to the importance it attaches to the survival of the organization, has placed its fundamental principle on increasing benefit and earning profit, therefore, morality is not its fundamental issue, and it can even commit immorality in some cases, according to the necessity of tendencies and dispositions . As a theoretician of Management ethics, from a historical point of view, the author has tried to show that business Management has always been associated with unethical experiences, an experience that has continued until the present day as a kind of modern slavery. He believes that Management ethics as an inter-discipline, which is considered a branch of Management knowledge in terms of its subject, must be more intertwined with philosophy in practice. Finally, although the author has been able to show the inherent contradiction of Management, especially business Management, with ethics and provide a solution based on this, the fact that the author has succeeded in presenting a different theory in the field of “Management ethics” is a matter of doubt and reflection.

Introduction: We compared the effect of the teaching aids and review Sessions on learning anatomy subjects by the medical students of Rafsanjan University of Medical Sciences.Methods: In this study, during each semester, practical anatomy courses were presented by using different teaching aids such as, cadaver, bones, and training videos to the students. For all studied groups, at the end of each semester and a few days before the final exam, the regular review Sessions were held by course lecturers. Then, student’s viewpoints about the effect of both teaching aids and review Sessions on their learning process were investigated, using the study checklist. Finally, the mean final scores of students who participated in the review Session were compared with those who did not.Results: The mean scores of anatomy practice exam (range 1-20) of students who did not participate in review Sessions were significantly lower than the student who did participate in these Sessions. Among the medical and dental students, a significant difference was reported with regard to the effectiveness of teaching aids and review Sessions on learning process. Viewpoint of senior students in comparison to junior students were more positive about practical courses and review Sessions. Overall, students’ viewpoints about the effect of both teaching aids and review Sessions on their learning process were positive and there was no significant difference between them with regard to their gender or field of study. However, medical and dental students believed that using teaching aids such as bones and models was very effective in their learning process of head and neck course. These opinions were significantly different between students of these two courses compare to students in the other courses (for models: P=0.022, for bones: P=0.007).Conclusion: Practical anatomy and review Sessions play an important role in the learning process of different subjects. Therefore, we suggest that practical courses and review Sessions be held with greater emphasis and for a longer time.

In this Session, we will discuss 7 cases in pediatric musculoskeletal field. These cases will include different aspects of bone and MSK disorders in pediatrics such as bone tumors (benign and malignant), bone involvement in metabolic and hematologic disorders, infectious diseases and soft tissue vascular lesions. During this Session, we will ask some volunteered radiology residents to explain the radiological findings and deliver their differential diagnosis. Then, they will discuss the case interacting with the audience who will also comment on the topic and finally the confirmed diagnosis that will be offered and discussed in more depth.

Parallel execution of multiple threads of a web application will result in server-side races if the web application is not synchronized correctly. Server-side race is susceptible to aws in the relation between the server and the database. Detecting the race condition in the web applications depends on the business logic of the application. No logic-aware approach has been presented to deal with race conditions. Furthermore, most existing approaches either result in DoS or are not applicable with false positive. In this study, the Session puzzling race conditions existing in a web application are classi ed and described. In addition, we present Business-Layer Session Puzzling Racer, a black-box approach for dynamic application security testing, to detect the business-layer vulnerability of the application against Session puzzling race conditions. Experiments on well-known and widely used web applications showed that Business-Layer Session Puzzling Racer is able to detect the business layer vulnerabilities of these applications against race conditions. In addition, the amount of tra c generated to identify the vulnerabilities has been improved by about 94. 38% by identifying the business layer of the application. Thus, Business-Layer Session Puzzling Racer does not result in DoS.
