This research aims to cast light upon security characteristics of the Peace Line, which have been underestimated. To understand maritime order and maritime security policy of the Republic of Korea between 1950 and 1970, it is necessary to analyze the Peace Line as line of defence and to investigate its character This research begins with analyzation of historical facts and investigation on security characteristics of the Peace Line. It goes further to examination of legal justification of the Peace Line, which was one of international legal issues of the period, principally regarding its security characteristics. As results of the study, it could be said that the security characteristics of the Peace Line was the line of defensive waters, which set its goal mainly to prevent infiltration of communist spies. The Peace Line had practical effect as it functioned as a base line of the ROK Navy to take anti-spy operation. At the early phase of the Korea-Japan Negotiation, the Korea delegation interpreted significance of the Peace Line passively. After abrogation of Clark Line, the delegation, however, became positive to maintain the Peace Line and its security characteristics. Security characteristics of the Peace Line was recognized again, as it became the base line of special maritime zone which was made in 1972. Through analysis on international law, it is concluded that the Peace Line was fair as a part of the right of self-defense against indirect aggression. North Korea attempted indirect aggression mainly from sea way, and these might undermine peace and cause urgent and unjust damage on the ROK. Thus the ROK's action of anti-spy operation through the Peace Line can be justifiable as considering the right of self-defence. Also the Peace Line accorded with principles of necessity, immediacy and proportionality. As it was argued on the above, the Peace Line as line of defence was one of the most significant factor in the ROK's maritime security history from the Hot war against communist forces to Cold war period after Korean War and must not be underestimated.

보안운영체제는 운영체제에 내재된 보안상의 결함으로 인하여 발생할 수 있는 각종 해킹으로부터 시스템을 보호하기 위해서 기존 운영체제에 다양한 보안기능을 추가한 운영체제이다. 보안운영체제는 시스템 보안을 목적으로 고안되었으나 전체 시스템의 안전을 위해서는 네트워크 측면에서의 보안이 필수적이다. 이를 위해서 IPsec이나 SSL과 같은 네트워크 보안 프로토콜들이 개발되어 사용되고 있으나 정책이나 키 관리에 많은 주의를 필요로 하고 보안운영체제의 특성을 반영하기 어렵다. 본 논문에서는 보안운영체제 사이에서 안전한 통신을 제공하기 위한 간단한 신뢰채널 메커니즘을 소개한다. 본 신뢰채널은 네트워크 트래픽에 대해 기밀성과 인증 서비스를 제공하며, 보안운영체제에 사용되는 특정 보안정보를 전달할 수 있는 구조를 가진다. IP 계층의 커널 수준에서 구현된 신뢰채널은 단순한 처리구조를 통하여 신뢰채널 처리과정에서 발생할 수 있는 오버헤드를 줄일 수 있다.

Carriage return (CR) and line feed (LF), also known as CRLF injection is a type of vulnerability that allows a hacker to enter special characters into a web application, altering its operation or confusing the administrator. Log poisoning and HTTP response splitting are two prominent harmful uses of this technique. Additionally, CRLF injection can be used by an attacker to exploit other vulnerabilities, such as cross-site scripting (XSS). Email injection, also known as email header injection, is another way that can be used to modify the behavior of emails. The Open Web Application Security Project (OWASP) is an organization that studies vulnerabilities and ranks them based on their level of risk. According to OWASP, CRLF vulnerabilities are among the top 10 vulnerabilities and are a type of injection attack. Automated testing can help to quickly identify CRLF vulnerabilities, and is particularly useful for companies to test their applications before releasing them. However, CRLF vulnerabilities can also lead to the discovery of other high-risk vulnerabilities, and it fosters a better approach to mitigate CRLF vulnerabilities in the early stage and help secure applications against known vulnerabilities. Although there has been a significant amount of research on other types of injection attacks, such as Structure Query Language Injection (SQL Injection). There has been less research on CRLF vulnerabilities and how to detect them with automated testing. There is room for further research to be done on this subject matter in order to develop creative solutions to problems. It will also help to reduce false positive alerts by checking the header response of each request. Security automation is an important issue for companies trying to protect themselves against security threats. Automated alerts from security systems can provide a quicker and more accurate understanding of potential vulnerabilities and can help to reduce false positive alerts. Despite the extensive research on various types of vulnerabilities in web applications, CRLF vulnerabilities have only recently been included in the research. Utilizing automated testing as a recurring task can assist companies in receiving consistent updates about their systems and enhance their security.

This study is to understand the situations of special education classroom layout, find differences according to school levels and summarize the findings in order to build up the indicators for special classroom layout. As for elementary school level, special classrooms are using multi-purposes desk or group desk for diverse activities such as basic learning and formation of basic life practice. The most frequent type in classroom layout is Type E which is for diverse coner-learning and play activities and the next is Type C which secures activity space. Because security of dynamic activity which most teachers find problematic is important, it needs more research to secure dynamic activity space within classroom. As for middle school level, the most frequent type in classroom layout is Type B which is equiped for computer aided learning and the next is Type C which secures activity space. Research for systematic layout of activity space is needed in order to secure the spaces of dynamic activity and basic job training. As for high school levels, mostly Type B which emphasizes computer activities is adopted and next is Type F which is capable for job training. The survey about the size of special education classroom proves that most teachers want one and half size classroom which in not such a large classroom. It is expected that more systematic research of special classroom layout according to school levels may reach for rational space layout.

The research involved children and parents of primary school-aged children with cognitive development disorder, as well as scientific and pedagogical workers who organized the psychological and pedagogical principles for organizing distance learning. The purpose of the research lies in establishing how effectively children, parents and their teachers cope with online distance learning during the pandemic, as well as investigating the extent to which such educational technology affects the emotional and behavioural state of the child. The research methodology is based on complexity. In the course of the research, the method of pedagogical experiment was used; observation and questionnaire methods were also introduced; the descriptive method, analysis and synthesis were used to review the theoretical material. The hypothesis lies in the fact that distance online education increases academic difficulties, changes the behavioural and emotional picture of a child with cognitive development disorder; consequently, the behaviour and emotional background will be limited by certain parameters, and this requires the active involvement of parents and teachers in the distance work process. The results of the research have revealed that distance education causes a number of restrictions for children with cognitive development disorder, namely: concentration of attention has decreased, anxiety has increased, and sleep has worsened. Behavioural changes predicted increased restlessness and aggression. Parents and teachers have had methodological, academic and everyday difficulties; all participants in the educational process have been more limited in the conditions of online distance learning. difficulties and improving the behaviour and emotional states of all participants in the educational process.

주요 선진국에서 민간조사제도는 민간경비업의 하나로 보편화되어 있고 국내에서도 민간조사제도의 필요성은 끊임없이 제기되고 있지만 아직까지 입법화 되지 못하여 불법적으로 운영되는 심부름센터는 그 수요에 따라 업무영역이 세분화되어 증가하고 있다. 이것은 경찰과 민간경비 모두 국민의 치안수요를 만족시키고 있지 못하고 있다는 반증인데 경찰은 수사, 교통, 정보, 방범과 같은 본연의 업무가 있고, 민간경비는 "경비업법"에 따라 시설경비, 호송경비, 신변보호, 기계경비, 특수경비로 업무 영역이 한정되어 있기 때문이다. 이 연구에서는 국내 민간경비 시장에 민간조사업의 접근에 따른 구조적 차이에 대하여 살펴보고자 하였고 이와 같은 질문에 민간경비업과 민간조사업은 매우 다르다(71.2%), 다르다(22.4%), 보통(6.3%), 비슷하다(0.0%), 매우 비슷하다(0.0%)순으로 응답하여 대체적으로 다른 업무로 인식하고 있는 것으로 나타났으며, 비수량분석 결과 그 차이는 업무성격, 비용, 업무수행범위, 공권력 영역, 법제의 유무, 위협대상, 조직규모인 것으로 나타났다. 국내에서 민간조사제도 도입을 위한 노력은 지난 1999년 하순봉의원의 발의 이후 현재 윤재옥의원의 "경비업법전부개정안"과 송영근의원의 "민간조사업에 관한 법률안"이 국회에 계류 중이다. 이 연구결과는 윤재옥의원의 "경비업법전부개정안" 법안과 같이 "경비업법"을 개정하여 민간조사업을 도입할 경우 민간경비업과 민간조사업의 차이점을 탐색적으로 살펴보고 정책적 제언을 하고자 한다.
