Recently, the rapidly development of computing environments and the spread of Internet make possible to obtain and use of information easily. Immediately, by opposition function the Hacker's unlawful intrusion and threats rise for network environments as time goes on. Specially, the internet consists of Unix and TCP/IP had many vulnerability. the security techniques of authentication and access controls cannot adequate to solve security problem, thus IDS developed with 2nd defence line. In this paper, intrusion detection method using Bayesian Networks estimated probability values of behavior contexts based on Bayes theory. The contexts of behaviors or events represents Bayesian Networks of graphic types. We profiled concisely normal behaviors using behavior context. And this method be able to detect new intrusions or modificated intrusions. We had simulation using DARPA 2000 Intrusion Data.

현대 사회에서 테러는 국제적으로 매우 빈번하게 일어나고 있으며, 대한민국도 더 이상 테러의 안전지대가 아니라는 뉴스가 보도되고 있다. 하지만 우리에 테러의 인식에 따른 시각은 다소 편협하여 성별, 나이, 직위, 장소등 많은 부분에서 갈등을 갖으며, 또한 한반도는 남북한의 갈등으로 인한 특수성은 게릴라 전을 테러라고 인식하는 시각이 있다. 국내 특수성으로 인해 테러를 전쟁의 영역으로 보고 테러대응 전략은 국가 안보로 많이 치우쳐져 있다. 역사와 정치적으로 또한 테러는 이념대립으로 인한 전쟁으로 치우쳐 전쟁의 전략에 한 부분으로 인식 되어 왔다는 것이 사실이다.(Rumyana G., 2014) 이는 전쟁의 시각에서 테러를 잘 설명하고 있다. 한편, 테러의 개념은 시간이 지남에 따라 기존의 안보의 개념뿐 아니라 재난의 개념에서도 찾을 수 있다. "불평등한 사회에 대한 민중의 분노로 이해하여야 한다"고 스위스 진보적 사회학자 장 징글러(Jean Ziegler) 는 말하며 무고한 사람들을 타겟으로 한 정치적 목적을 이루기 위한 비합법적 무력 사용으로 보았다. 즉, 비합법적 무력사용으로 무고한 다중(Innocent people)에게 폭력을 행사한 것이다. 젠킨스와 라쿼르의 정의를 살펴보면 "테러리즘이란 폭력 혹은 폭력의 위협이다"라고 정하였다.(Jenkins 2004) 폭력이란 형법에서는 다른 사람에게 상해를 입히거나 협박하거나 하는 등의 행위와 함께 다른 사람을 감금하는 행위, 주거에 침입하는 행위, 기물의 파손 등에 대해서도 폭력이라 표현한다. 철학, 정치학 등의 학문에서는 다른 사람 또는 국가나 세력을 제압하는 힘을 일반적으로 지칭하기도 한다. 힘자랑이나 힘겨루기가 이에 속한다. 무력의 사용으로 사회에 심리적인 영향을 끼치며 사회적 파괴를 일으키는 것을 보편적 테러의 개념으로 볼 수 있다. 테러는 국가 통치 질서와 사회질서 안정에 큰 위협과 혼란을 초래하는 파괴행위의 무력행사로 국가의 재난 상황을 유발하는 인류가 만든 재난으로 볼 수 있다. 자연현상으로 발생하는 자연재해는 인류의 시점에서 재난으로 해석된다. 마찬가지로 사회현상으로 발생하는 폭력적 파괴행위에 대한 피해는 인류의 시점에서 재난의 현상으로 해석 되어야 한다. 과학기술이 발달하면서 첨단기술을 이용한 폭력행위와 파괴의 두려움은 정보통신 기술의 발달로 두려움의 전파 속도도 빨라 질 것이다. 따라서 테러행위의 극복을 위해서는 테러를 인적재난(Man-made Disaster)로 보고 재난의 범주로 포함하여 미래의 테러를 위한 대비전략을 수립해야 할 것이다. 이를 위해 본 논문에서는 학계의 학자들과 기관 및 민간 의 전문기관들에 따른 테러의 정의를 분석하고 재난정의를 고찰하여 시사점을 제시하고, 대테러 대비 전략의 방향에 기틀을 마련하고자 테러정의를 도출하였습니다.

Despite anti-corruption has been one of the major governmental tasks in Korea, anti-corruption policies have been focused largely on government officials in public sectors, and most of the prior studies have examined government employees not public citizens. In order to fill the vacuum in the literature, this study aims to develop evidence-based anti-corruption policies via a survey of people in various job categories for the relationship between their experiences of any corruption and related factors. Researchers analyzed a secondary data gathered by the Korean Institute of Public Administration, which included a sample of 1,000 adults aged over 19. The results showed that indirect experiences of corruption and interaction with the corrupted were positively related to individuals' corruption behaviors. In addition, their perception towards low- and mid-ranking officials were statistically signifiant in explaining the corruption behavior. Thus, policy-makers should consider focusing on indirect experiences of corruption, interaction with the corrupted, and perception towards low- and mid-ranking officials. This study contributed as an attempt to suggest policy implications and further research ideas by examining factors related to individuals' corruption behaviors.

The purpose of this study was to investigate the nursing behavior and delegation status of nursing hospital nurses and to provide basic data for improving the quality of medical services. The subjects of this study were data collected from July 26 to December 23, 2013, for 140 nurses with more than 3 years of experience in nursing hospitals. Collected data were analyzed by frequency analysis, mean and standard deviation, independent t-test and One way ANOVA of SPSS 20.0 statistical program. Collected data were analyzed by frequency analysis, mean and standard deviation, independent t-test and one way ANOVA of SPSS 20.0 statistical program.. As a result of this study, the case of delegation of nursing behavior was higher in case of no protocol of nursing delegation procedure than in case of having protocol. This study suggests that nursing practice of nursing hospital nurses can be a major factor in declining the quality of medical services in the absence of specified standards or procedures for delegation. Procedures, methods and guidelines are required.

This study was conducted to find the relation among perceived health status, self-esteem, self-efficacy, and social support related with the health behavior in the aged, and to ascertain the factors which affect the health behavior in the aged. For this study, 271 old men and women were surveyed from June to July, 2008, who lived in Daejeon and Chungnam province, and were 65 years old and over. As a result, it was surveyed that the old having their religious beliefs were good in health behavior, and the old who had a spouse and a high level of education were good in health status. And also, old women had a higher self-efficacy than old men, and the old who had a high level of education had a higher self-efficacy than those who didn't. Among the subjects of this study, there was a significant correlation between the health behavior in the aged and perceived health status, self-esteem, and self efficacy, and one between perceived health status and self-esteem, and self efficacy. And also, there was a significant correlation between self-esteem and self efficacy. Self-esteem was confirmed as the important variable which affected the health behavior of the aged. The limitations, implications of this study and future tasks for the old were discussed.

This paper proposes normal behavior profiling methods for anomaly detection in IEC 61850 based substation network. Signature based security solutions, currently used primarily, are inadequate for APT attack using zero-day vulnerabilities. Recently, some researches about anomaly detection in control network are ongoing. However, there are no published result for IEC 61850 substation network. Our proposed methods includes 3-phase preprocessing for MMS/GOOSE packets and normal behavior profiling using one-class SVM algorithm. These approaches are beneficial to detect APT attacks on IEC 61850 substation network.

With the recent development of deep learning technology, computer vision-based AI technologies have been studied to analyze the abnormal behavior of objects in image information acquired through CCTV cameras. There are many cases where surveillance cameras are installed in dangerous areas or security areas for crime prevention and surveillance. For this reason, companies are conducting studies to determine major situations such as intrusion, roaming, falls, and assault in the surveillance camera environment. In this paper, we propose a real-time abnormal behavior analysis algorithm using object detection and tracking method.

Objectives: This research aimed to identify the level of perception, knowledge, preventive behavior, and factors affecting preventive behavior of patients with asthma and chronic obstructive pulmonary disease against particulate matter. Methods: This research was a descriptive survey research, and the subjects were chronic pulmonary disease patients over the age of 19 and under 80 who visited a university hospital in Daegu City. Data was collected by convenience sampling through structured self-administered questionnaire survey from December 2019 to January 2020, and a total of 212 copies were used for analysis. Results: Out of 212 total subjects, 112 were asthma patients (52.8%) and 100 were chronic obstructive pulmonary disease patients (47.2%). The average score (out of 10) of perception, knowledge and preventive behavior of patients with asthma for particulate matter was 7.92, 6.99, and 7.10, respectively, while those with chronic obstructive pulmonary disease scored 7.72, 6.24, and 6.80, respectively. The knowledge score was significantly higher in patients with asthma than those with chronic obstructive pulmonary disease (p=0.007). Factors affecting particulate matter preventive behavior were perception score, knowledge score, and age for asthma patients, and perception score for chronic obstructive pulmonary disease patients. Conclusions: As a result of the above, the factors relate to the preventive behavior of patients with asthma and chronic obstructive pulmonary disease were perception score, knowledge score, and age for asthma, and perception score for chronic obstructive pulmonary disease. Raising the level of particulate matter preventive behavior can prevent the deterioration of chronic pulmonary diseases caused by particulate matter, so the development of arbitration programs considering the characteristics of the patients according to the disease and continuous and repetitive education are required.
