침해사고는 시스템 해킹, 바이러스 및 웜, 홈페이지 변조, 자료 유출 등 그 유형이 다양하고, 단순한 바이러스나 웜 등의 유포가 아닌 개인정보 및 기업기밀 정보를 취득하거나 금전적 이득을 취하기 위한 목적으로, 공격자가 사용하는공격 기법이 고의적인 데이터의 삭제나 변경 등 고도의 은닉 기법을 활용하여 흔적을 남기지 않기 때문에, 정확한 자료를 수집하기가 쉽지 않다. 침해사고 초기 대응시 초동 대응자는 신속한 조사를 수행해야할 필요가 있는 침해위협 또는 범죄와 관련 현장 정보를 취급한다, 이때 체계적인 증거 수집을 위하여 침해사고의 식별에 적합한 디지털 포렌식 프로세스 방법론의 적용이 요구된다. 본 논문에서는 초동 대응자가 효과적인 초기 대응을 위하여, 윈도우 시스템 환경에서의 디지털 포렌식 측면에서 CFFTPM 포렌식 프로세스 모델을 적용하여 사용자 사용 정보, 타임라인 정보, 인터넷 정보 등 증거 수집 기본정보를 분석하고 이에 따라 클라이언트/서버 모델로 증거수집 응용시스템을 설계하고 이를 구현하였다.

Purpose: This study was conducted to evaluate the effectiveness of an evidence-based nursing (EBN) course using action learning-based team learning in undergraduate nursing students. Methods: A quasi-experimental pretest-posttest control group design was employed. The participants who consented were 45 second-year nursing students (22 in the experimental, 23 in the control group) from a university in G-city, Korea. The intervention included lectures, practicals, team activities and reflection on overviewing EBN, formulating clinical questions, searching the evidence, and criticizing the research articles. At the beginning and the end of the 7-week EBN course, the participants completed self-reported questionnaires. Frequencies, $x^2$-test, t-test, and ANCOVA with the SPSS program 18.0, were used to analyze the data. Results: The experimental group showed significantly higher scores on EBN competency (F=25.80, p<001), information literacy (F=13.75, p=.001), and proactivity in problem solving (F=5.32, p=.026) than the control group. Conclusion: This study provides evidence that an EBN course improves undergraduate nursing students' EBN competencies, information literacy, and proactivity in problem solving. Team learning in EBN education can be an effective teaching strategy.

Variable selection in oriental medical research is considered. Decision tree analysis algorithms such as CHAID, CART, C4.5 and QUEST have been successfully applied to a medical research. Paralysis disease is a highly dangerous and murderous disease which accompanied with a great deal of severe physical handicap. In this paper, we explore the use of CHAID algorithm for selecting variables for evidence-diagnosis of paralysis, disease. Empirical results comparing our proposed method to the method using Wilks $\lambda$ given.

범죄수사에서 디지털증거가 중요해지면서 법정에서 다툼이 많아지고 있다. 매체가 다양화되고 분석범위가 확장되면서 디지털포렌식에 대한 전문성 수준도 높아지고 있다. 그러나 아직까지 디지털증거분석관의 역량을 정의하거나 전문성을 판단하는 역량모델 개발은 이루어지지 않고 있다. 디지털증거분석관에게 필요한 역량을 도출한 일부 연구가 있었으나 여전히 미흡한 수준이다. 따라서 본 연구에서는 전문가 FGI, 델파이 조사 등의 방법론을 활용해 총 9개의 역량군 25개의 역량평가 요소를 정의하였다. 구체적으로 디지털포렌식 이론, 디지털증거 수집 및 관리, 디스크포렌식, 모바일포렌식, 영상포렌식, 침해사고포렌식, DB포렌식, 임베디드(IoT)포렌식, 클라우드포렌식으로 규정하였다. 디지털증거분석관 역량모델은 향후 선발, 교육훈련, 성과평가 등 다양한 분야에 활용할 수 있을 것으로 기대한다.

Objective: The purpose of this study was to identify the practitioner and organizational characteristics that either detracted from or encouraged the use of evidence-based practice (EBP) by physical therapists. Design: A cross-sectional survey study Methods: Participants were 260 physical therapists currently practicing in South Korea. They completed a questionnaire designed to determine attitudes, beliefs, interest, self-efficacy and barriers to EBP, as well as demographic information about themselves and their practice settings. Logistic regression was used to examine relationships between socio-demographic and work environment characteristics and each practitioner factor. Results: Respondents agreed that the use of evidence in practice was necessary. Although 80% of them agreed that research findings are useful, 71% felt that a divide exists between research and practice. In terms of confidence in their skills, the ability to interpret results of statistical procedures ranked lowest. Despite internet access at work for 63% of respondents, only 14% were given protected work time to search and appraise the literature. Only 2% of respondents stated that their organization had a written requirement to use current evidence in their practice. The primary barrier to implementing EBP was a reported lack of time. Conclusions: In conclusion, most physical therapists stated they had a positive attitude toward EBP and were interested in learning or improving the skills necessary for implementation. Most recognized a need to increase the use of evidence in their daily practice, but a lack of ability to understand the results of research represents a significant barrier to implementing EBP.

It is becoming more important as the growing of health information and increasing in cancer patients diagnose over the time gradually. Among the various types of cancer, we focuses on breast cancer diagnosis. The accuracy of breast cancer diagnosis is increasing when the diagnosis is based on evidence and statistics. To do this we use the weka data mining tools and analysis algorithms significantly associated with the decision tree uses rules. In addition, the data pre-processing and cross-validation are used to increase the reliability of the results. The number and cause of the disease becomes important to increase evidence-based medical doctors. As the evidence-based medical, the data obtained from patients in the past through the disease by calculating the probability for future patients to diagnose and predict disease and treatment plan. It can be found by improving the survival rate plays an important role.

The forms of current war are diversified over the pan-national industry. Among these, one kind of threats which has permeated the cyber space based on the advanced information technology causes a new type of war. C4ISR, the military IT revolution, as a integrated technology innovation of Command, Control, Communications, Computer, Intelligence, Surveillance and Reconnaissance suggests that the aspect of the future war hereafter is changing much. In this paper, we design the virtual decoy system and intrusion trace marking mechanism which can capture various attempts and evidence of intrusion by hackers in cyber space, trace the penetration path and protect a system. By the suggested technique, we can identify and traceback the traces of intrusion in cyber space, or take a legal action with the seized evidence.

The evaluation process of rock mass properties intrinsically contains some uncertainty due to the inhomogeneity of rock mass and the measurement error. Although various empirical methods for the determination of rock mass properties were suggested, there is no way of integrating various information on rock mass properties except averaging. For these reasons, this research introduces evidence theory which can model epistemic uncertainty and yield reasonable rock mass properties through combining various information such as empirical equations, in-situ test results, and so on. Through the application of evidence theory to the real site investigation and in situ experiment results, an interval of deformation modulus, cohesion and friction angle of rock mass were obtained. The ratios between lower and upper bound of those properties ranges from 1.6 to 3.6. Numerical analyses of circular hole using the properties for TYPE-2 rock mass were carried out. The magnitude or size of plastic region and radial displacement in case of lower bound properties is about 4 times larger than that of upper bound properties.

Purpose: The purpose of this study was to explore nurses' access and use of information resources and to identify the barriers and competency to evidence based practice (EBP). This study used descriptive method to identify baseline data for the purpose of developing strategies for establishing EBP in clinical nursing practice. Methods: Participants in this study were 278 nurses from five hospitals in Daegu and Kyungsangbukdo. The data were collected by self administered questionnaires and SPSS/WIN 15.0 program was used to analyze the data with descriptive statistics, t-test, Pearson's correlation coefficients, and ANOVA. Results: Nurses reported $^*most$ frequently using paper and human resources. The mean score of barriers was $3.02{\pm}0.41$, and competency was $2.70{\pm}0.50$. The reported competency was correlated with nurse factors (r=-.31, p<.001) organization factors (r=-.20, p<.001) and research factors (r=-.12, p<.040) as the barriers to evidence based practice. Conclusion: To promote competency in EBP and to decrease the barriers, it would be necessary to develop the organizational culture that encourages nurses to be involved in research activities. In addition, the development of systemic methods to introduce and establish an education program for facilitating EBP in the clinical settings is needed.
