오늘날의 정보시스템 환경에서는 물리적인 접근 통제나 정보보호기술 측면에서의 통제만으로 정보자원을 효과적으로 보호하기 어렵다. 흔히 정보보호는 기술보다는 관리의 문제라고 한다. 따라서 효과적인 정보보호는 조직 구성원의 정보보호 중요성에 대한 인식을 전제로 하며, 인식을 높이기 위해서는 적절한 교육과 훈련이 수반되어야 한다. 본 연구에서는 사회심리학 관점으로부터 의사결정과정 측면과 교육 및 훈련의 효과성 측면에서 정보보호에 대한 사용자의 실제 행동과 내면화 과정을 규명하였다. 이를 토대로 조직 구성원이 지속적인 정보보호 실제 행동을 할 수 있는 정보 보호 교육 및 훈련 프레임워크를 제안하고, 구성요소별 전략과 프로그램의 실행 단계를 소개하였다.

정부의 녹색성장 정책에 의해 배전계통에 태양광, 풍력발전 등 분산전원의 설치가 급증함에 따라 기존의 배전계통의 조류의 방향 및 고장전류, 부하전류가 변화되어 배전계통의 보호협조 운용상에 여러 가지 문제점들이 발생할 가능성이 커지고 있다. 특히 분산전원연계시 임피던스 병렬화로 보호기기에 흐르는 사고전류가 감소하는 분류효과가 발생할 가능성이 있다. 따라서 본 논문에서는 분산전원이 연계된 경우 보호협조를 검토하기 위한 양방향 보호협조 평가프로그램을 이용하여 분산전원이 연계된 경우 계통에서 발생할 수 있는 문제점 중 분류 효과로 인한 보호기기의 부동작 사례를 시뮬레이션하고, 그 결과를 분석하여 본 프로그램의 유용성을 확인하였다.

This study developed a relapse prevention program for substance abusing women and evaluated its effectiveness. The major contents of the program include to enhance cognitive and behavioral coping skills, to identify and expand supportive social networks, and to deal with women-related issues. The program was operated 3 times with 24 female clients in a probation office in Seoul from August 2003 to October 2004. The program changed the participants' attitudes toward substance use and improved their drug-refusal skills. This study mentions that the findings may be useful for practitioners as well as researchers because this study was first one that dealt with a women-only group in Korea. Finally, this study suggests that more studies be conducted in order to provide better understandings on substance abusing women and more effective interventions skills.

Many researches have been performed to resist buffer overflow attacks. However, the attack still poses one of the most important issue in system security field. It is because programmers are using library functions containing security hole and once buffer overflow vulnerability has been found, the security patches are distributed after the attacks are widely spreaded. In this paper, we propose a new cache level return address stack architecture for resisting buffer overflow attack. We implemented our hardware onto SimpleScalar simulator and verified its functionality. Our circuit can overcome the various disadvantages of previous works with small overhead.

Recently, the importance of information security is emphasized in IT related field. The agency related to information security implements the policies to emphasize the security and protection of the privacy. However, the issue in many companies and users is that awareness of security is still poor. Therefore, in this paper, we develope the learning program for AES(advanced encryption standard) block cipher, to raise the awareness of security. Also, wish to cause interest about AES cipher because user confirms process that is encryption/decryption through program of this paper directly and prove awareness about information security.

The purpose of this study was to research the perception on patient private information protection of 126 nursing students before clinical practice. The mean score of perception on patient private information protection was 4.52 points of full 5. The perception of protecting patient privacy was no significantly differentiated with general characteristics of nursing students. Development and application of patient private information education program for inexperienced nursing students is necessary. Also it is necessary to seek joint plans between medical institutions and universities to improve the awareness of patient privacy.

The purpose of this study was to evaluate the effects of the meaning of life, change to attitude toward the old and hospice perception through pre/post hospice education program of care worker trainees. Methods: This study is a quasi-experimental research using one group pretest-posttest design. The research period was from May to June, 2011. The subjects of the study were 53 care worker trainees in T city and S city. The data were analyzed by SPSS/WIN 17.0 program with descriptive statistics and paired t-test, mean, standard deviation. The period of this study was from May 9 to June 20 of 2011. Results: The meaning of life and hospice perception were significantly different between pre- and post-program. The attitude toward the old did not show a significant difference before and after the program. Conclusion: This study is need to improve hospice education program for comprehend meaning of life, change to attitude toward the ole and improve hospice perception.

Virtualization obfuscation makes hard to analyze the code by applying virtualization to code section. Protected code by common used virtualization obfuscation technique has become known that it doesn't have restored point and also it is hard to analyze. However, it is abused to protect malware recently. So, It is been hard to analyze and take action for malware. Therefore, this paper's purpose is analyze and take action for protected malware by virtualization obfuscation technique through implement tool which can extract virtualization structure automatically and trace execution process. Hence, basic structure and operation process of virtualization obfuscation technique will be handled and analysis result of protected malware by virtualization obfuscation utilized Equation Reasoning System, one kind of program analysis. Also, we implement automatic analysis tool, extract virtualization structure from protected executable file by virtualization obfuscation technique and deduct program's execution sequence.

The purpose of this study was to examine the impact of education for welldying on the death anxiety and death reception of care workers who were most closely linked to death among workers who were engaged in senior welfare. It's basically meant to let care workers have a good understanding of death, death process and death-related factors to help elderly people close their life in a comfortable manner. The subjects in this study were the care workers who worked in J nursing home in the region of Gwangju. They received education in nine sessions, once a week, and the collected data were analyzed by the statistical package 15.0. The statistical analysis methods used in this study were reliability analysis, descriptive statistics analysis, t-test and ANOVA. The findings of the study were as follows: First, the welldying program participants showed a decrease in death anxiety. Second, the welldying program participants became more receptive to death.

기존의 고정적 웹 페이지에, 실시간적으로 변화하는 내용의 제공을 가능하게 하기 위해, 추가적으로 코드를 첨가할 수 있도록 만든 것이 웹 응용 프로그램이다. 그 예로는 cgi, php, jsp, java, python 등이 있다. 많은 수의 언어와 다수의 프로그램들이 빠른 속도로 개발됨에 따라 많은 수의 보안 문제점들이 발생하였고 실제로 대단히 많은 서버들이 침입의 대상이 되었다. 웹 응용 프로그램의 보안에 많은 문제점이 발생한 이유는 첫번째, 기존의 서버 응용 프로그램들에 비하여 웹 응용 프로그램은 휠씬 많은 수가 아주 빠르게 개발되었다는 점이다. 두 번째는 웹 응용 프로그램에서 발생한 새로운 종류의 보안 위험성을 들 수 있다. 기존의 서버 응용 프로그램에서 발생하는 위험성들은 서버프로그램의 버그를 이용한 것이었고, 이들은 외부 입력의 내용보다는 그 크기 등의 간단히 검사 가능한 특징에 의존하는 경우가 많았다. 하지만, 웹 응용 프로그램이 외부 입력의 내용을 코드의 일부로 사용하는 경우가 많음으로 인해서, 웹 응용 프로그램에서는 간단히 검사하기 어려운 특징인 입력의 내용에 의존하는 위험성들이 많이 발생한다. 본 논문에서는 이러한 새로운 방식의 위험성을 소스코드를 이용해서 어떻게 자동적으로 검사할 수 있을 지에 관해서 새로운 아이디어를 제시한다. 이 아이디어는 현재 구현 중에 있으며, 초기 실험 결과 기존의 검사 프로그램들이 찾아내지 못하는 취약점들을 찾아낼 수 있음이 확인되었다.
