Recently the paradigm of cyber attacks is changing due to the information security technology improvement. The cyber attack that uses the social engineering and targets the end users has been increasing as the organization's systems and networks security controls have been tightened. The 91% of APT(Advanced Persistent Threat) which targets an enterprise or a government agency to get the important data and disable the critical service starts with the spear phishing email. In this paper, we analysed the security threats and characteristics of the spear phishing in detail and explained why the technical solutions are not enough to prevent spear phishing attacks. Therefore, we proposed the administrative prevention methods for the spear phishing attack.

This paper introduces a possibility for attackers to acquire the keyboard scan codes through using the RESEND command provided by the keyboard hardware itself, based on the PS/2 interface that is a dominant interface for input devices. Accordingly, a keyboard sniffing program using the introduced vulnerability is implemented to prove the severeness of the vulnerability, which shows that user passwords can be easily exposed. As one of the intrinsic vulnerabilities found on the existing platforms, for which there were little considerations on the security problems when they were designed, it is required to consider a hardware approach to countermeasure the introduced vulnerability.

매크로 프로그램에 의한 피해는 꾸준히 보고되어 왔다. 최근 코로나 19로 인해 마스크 품귀 현상이 발생하여 매크로 프로그램을 이용한 구매가 사회적 이슈로 떠오르면서 매크로에 대하여 법적 처벌을 하는 등 매크로에 대한 관심이 부각되고 있다. 본 논문에서는 매크로 프로그램을 효과적으로 탐지하기 위한 방법을 제안한다. 본 논문에서는 매크로 탐지를 위해 access.log의 다양한 필드를 분석하고, 이 중 매크로 식별에 효과가 있는 필드를 추출하여 매크로를 탐지한다. 제안하는 기술의 효과성 검증을 위해 매크로의 공통적인 기능이 포함된 매크로 프로그램을 직접 제작하고, 실제 구매 웹사이트와 유사한 판매 사이트를 제작하여 실험을 통해 제안하는 방법이 매크로를 효과적으로 탐지하는 것을 보인다.

The object of this dissertation is to teach the divorced inmates the method to deal with the conflicts which they have had. This program constitutes 10 terms session, and the participants are 6 at first, but reduced one latter. In the process of the program, when making nickname, the participants preferred the words that present their personal emotion and experience. And the participation rate by each participants were ascent more and more in accordance with the process. After the whole process of the program, we executed conflict-dealing scale test before and after the program. The result showed that 'Patience' and 'Siloam' presented change from emotional dealing to rational dealing. 'Sea', 'Jin' and 'Birth' presented higher level of emotional dealing than before the test. Therefore Through this result, we knew that conflict-dealing method program improved the skills and abilities which are used for the situation making conflicts.

This thesis is the study of the analysis about Direction of Promote and Acquisition Program of Human Strength. Now we have question 'How we should develop the human resources program to gain human strength in the strategic environment of the future?' We know that if we don't estimate our project precisely, then we can't get good human resources. The purpose of this study is to find the way that how to gain excellent human resources now and in the future. The Ministry of National Defense to study US military Acquisition system. Korean military strategy in the situation of the confrontation between South and North Korea and in the situation of the international relationship and the way of constructing the military strength for the future. To improve Acquisition Program of Human Strength, we must develope and assess the future strategic environment of the Korean Peninsula especially Acquisition Program of Human Strength.

The current research aimed to ascertain the effectiveness of the early intervention program based on electronic games in developing the visual perception of children with intellectual disabilities within the age group of (2-5) years, using the quasi-experimental approach with one group, and the study sample consisted of (11) children with disabilities. Simple and medium intellectuals enrolled in the early intervention program at the Successful Communication Center for Day Care in Makkah Al-Mukarramah and were deliberately selected. To achieve the research objectives, the researchers prepared and applied the visual perception scale after ensuring its validity and stability. Three electronic games were also designed and applied to the sample for (17) sessions. The results showed the effectiveness of the electronic games program in developing the visual perception of children with intellectual disabilities within the age group (2-5) years and maintaining this improvement over time. Where the results showed that there were statistically significant differences at the level (α = 0.05) between the grades of the group children in the pre and post-measurements on the visual perception skills scale for children with intellectual disabilities in the post-measurement after applying the program, in favor of the post measurement. The results also showed that there were no statistically significant differences at the level (α = 0.05) between the grades of the group children in the two post and follow-up measurements on the visual perception skills scale for children with intellectual disabilities in the follow-up measurement which indicates the long-term impact of the program. The researchers recommend the necessity of activating educational programs based on various electronic games to develop the visual perception of children with intellectual disabilities and employ them effectively in the educational process for children with intellectual disabilities.

A movie information program has a positive effect on the viewer's intention to watch the movie by providing an indirect experience of the movie based on trust. In order to increase the effectiveness of a movie information program, a data service that provides the additional information on the movies introduced in a movie information program has been studied. However, since the study limited the data service to one movie information program, it was difficult to apply it to the actual environment of general cable broadcasting companies or satellite broadcasting companies that transmit multiple movie information programs. Therefore, this study expanded the existing research limited to one movie information program to provide additional information of several movie information programs. This study is meaningful in that it suggests a data service that can be operated in the realistic environment of a broadcaster that actually transmits several movie information programs.

Because the movie has the characteristics of a cultural product where experience is important, a promotional strategy is used to convert viewers into movie audiences by providing indirect experiences of movies through professional movie information programs. Considering that the movie information program is a strategic publicity medium that raises the audience's intention to watch a movie, a study on the data service that provides useful additional information to the viewer in conjunction with the movie information program is meaningful. Against this background, this study contains the core research contents in the development of data service linked with movie information program. Specifically, additional information of the movie information program was defined. And to provide the additional information to the data service, the digital broadcasting international standard DVB-SI-based additional information transmission method was devised.
