Security operating system applied to MAC(Mandatory Access Control) or to MLS(Multi Level Security) gives both subject and object both Security Level and value of Category, and it restrict access to object from subject. But it violates Security policy of system and could be a circulated course of illegal information. This is correctly IPC(Interprocess Communication)mechanism and Covert Channel. In this thesis, I tried to design and implementation as OS kernel in order not only to give confidence of information circulation in the Security system, but also to defend from Covert Channel by Storage and IPC mechanism used as a circulated course of illegal information. For removing a illegal information flow by IPC mechanism. I applied IPC mechanism to MLS Security policy, and I made Storage Covert Channel analyze system call Spec. and than distinguish Storage Covert Channel. By appling auditing and delaying, I dealt with making low bandwidth.

The National Assessment of Educational Achievement has been conducted in the form of sampling assessment until 2007, but it was converted into sampling assessment one hundred percent working with relevant whole students in 2008. Therefore, the necessity of new study on the national assessment system of educational achievement was on the rise. The National Assessment System of Educational Achievement, which was implemented in this thesis was designed to analyze educational achievement status all over the province, total score and score frequency distribution per subject, item difficulty and item discrimination, degree of attraction of wrong answers, educational achievement per subject, gender, region, office of education, school, individual and status of students with high educational achievement.

Most previous studies on A Gesture Life focused on illuminating the role and significance of Kkutaeh, the Korean comfort woman, whom Hata runs across at a military camp in the Burmese jungle. For instance, Carroll Hamilton argues that the return of Kkutaeh as a traumatic subject disrupts Hata's nationalist narrative, causing the protagonist's eventual failure at national enfranchisement. However, this paper focuses on Hata's relationship with Bedley Run, the sleepy suburban white town, in which the protagonist settles down right after immigration to the US. The racial/racist nature of Bedley Run has not received due critical attention, although a few studies on the novel saw Hata's gestures as a survival tactic deployed against the hostile environment of his new host society. This paper, resorting to Pierre Macherey's thesis on symptomatic reading, exposes what Hata, the narrator/protagonist, hides from his readers concerning his status in his muchbeloved town; and it also explores the subversive significance of Hata's ethnic memories. The aim of this study is, after all, to map both the subversive possibilities and the limitations of Hata's immigrant narrative as a bildungsroman.

The purpose of this thesis is to derive a strategy to establish an ecosystem for promoting health my data projects in the public domain. To this end, first, the types of my data business were classified by business domain, subject, purpose, and method, and based on this, my data business being promoted in Korea and abroad was analyzed by type. After that, based on the analysis results, scenarios for my data projects that public domain can promote and the roles and major issues of each subject were identified, and the strategic direction for each subject of the ecosystem was presented. Such an attempt is of primary significance in revealing the role that the health MyData project can take the lead in the public domain to settle in Korea targeting sensitive information. Through this, it is expected that it will be a cornerstone of discussion to identify issues that are expected to establish an ecosystem in Korea, and to present a direction in which the my data business can be promoted in the right direction in the future.

Objective : This study examined the characteristics of the literature involving a single-subject research design among positive behavior support intervention studies to improve problem behavior in children with autism spectrum disorders and assess the quality level. Methods : This is a literature study, and the targets of analysis were nine single-subject research papers published between 2011 and 2020. The subject papers were analyzed by dividing them into general characteristics and the qualitative levels according to the content of the research method. Results : Analysis of analyzing the contents of the study showed that the subjects were preschool and elementary school-age children at the same ratio. Furthermore, the study design involved mostly the middle and multiple baseline designs among the behaviors. All papers presented social validity, intervention fidelity, and observer reliability. Problem behaviors included self-injury and aggression behaviors, disturbing behaviors, and seat break-away behaviors, while the most dependent variables were measured through partial interval recording. As a result of confirming the intervention effect, the effect was confirmed in intervention, maintenance, and generalization. All analysis studies showed high-quality levels. Conclusion : This study confirmed the content and qualitative level of the thesis that applied the single-subject research design among positive behavior support intervention studies for problem behaviors of children with autism spectrum disorders. Positive behavior support intervention, an evidence-based intervention for children with autism spectrum disorders, was confirmed an effective intervention for autism spectrum disorders.

In the present architectural culture of Korea, the expression of Korean values and the contemporary trends of global architectures are not identified and arranged distinctly, so diverse tendencies are applied to the architectures of Korea recklessly. In this situation, minimal architecture is significant, which pursues the essence of architecture through the minimal materials. This thesis analyzes the characteristics of minimal architecture seeking after the essence of architecture by minimalization and examines Seung, Hyosang's architectures showing expressional traits similar to those of minimal architecture in the modem architectures of Korea, so this study can show the expressional characteristics and materials of minimal architecture. Nevertheless, it does not mean that all the Seung, Hyosang's works have the tendency of minimal architecture and that he has to be classified as a minimal architect, but it means only that the values and thoughts like the expressional traits of minimal architecture are seen in his architectural opinions! and works, which will be the subject of this study.
