Recently many important systems that used to be operated in a closed environment are now providing web services and these kinds of web-based services are often an easy and common target of attacks. In addition, the great variety of web content and applications cause the development of new various intrusion technologies, while the misuse-based intrusion detection technology cannot keep the peace with the attacks and it seems to lack the capability to deal with such various new security threats, As a result it is necessary to research and develop new types of detection technologies that can detect newly developed attacks and intrusions as well as to be able to deal with previous types of exploits. In this paper, a HTTP traffic model is tested for its anomaly by using a HTTP request traffic pattern analysis and the field information analysis of the HTTP packet. Consequently, the HTTP traffic models by applying anomaly tests is designed and established.

The purpose of this study is to analyze the means of accounting fraud in Chinese listed agricultural companies and to suggest methods for the prevention of accounting fraud and follow-up measures. In this study, 21 Chinese agricultural enterprises were investigated and counted by means of accounting fraud. The means of accounting fraud of listed companies related to agriculture mainly consisted of profit inflation, inflating their net assets, the disclosure of accounting information violations, asset inflation for net asset inflation, and the incomplete disclosure for accounting information violations. Among these, income forgery was the most frequent among the 21 companies surveyed as a means of accounting fraud in profit inflation. Through this study, in the field of auditing academically, it is possible to find the motives of fraudulent acts in Chinese agricultural enterprises and to obtain advice to reduce fraudulent acts, and it will be of great help in theoretical research related to accounting frauds.

Vulnerable web applications have been the primary method used by the attackers to spread their malware to a large number of victims. Such attacks commonly make use of malicious links to remotely execute a rather advanced malicious code. The attackers often deploy malwares that utilizes unknown vulnerabilities so-called "zero-day vulnerabilities." The existing computer vaccines are mostly signature-based and thus are effective only against known attack patterns, but not capable of detecting zero-days attacks. To mitigate such limitations of the current solutions, there have been a numerous works that takes a behavior-based approach to improve detection against unknown malwares. However, behavior-based solutions arbitrarily introduced a several limitations that made them unsuitable for real-life situations. This paper proposes an advanced web browser based malicious behavior detection system that solves the problems and limitations of the previous approaches.

This study is to criticize whether festivals as cultural activities form cultural values by questioning about the animal cruelty in Korean festivals. Changes in the social awareness of animals and the viewpoint that shifted from human-centered thinking to values of the environment and life served as an opportunity to look back on animals. This study looked at festivals using animals in Korea and especially analyzed the four major animal festivals that have been criticized. A qualitative study method interpreting opinions, evaluations, alternatives, and arguments of cultural tourism and animal rights experts was implemented by conducting interviews with experts of cultural tourism and animal rights, who have conflicting views about animal festivals. The primary topic of discussion is a sharp criticism that 'sales of products based on innocence' is a commercialized cultural value. The expression that 'wrongful traditions do not need to be protected' is an escape from the customary memory of traditions that do not create cultural values. The act of stopping the long malpractice of traditional animal violence is the very act of creating 'cultural values.'

The purpose of this study was to examine the effect of an ICT based integrated dementia prevention program on vitality, fear of dementia, preventive behavior of dementia in the elderly using senior citizen centers. The experimental treatment was given an ICT based integrated dementia prevention program for the preventive behavior of dementia for 12 sessions over 6 weeks by the one group pretest-posttest design. Data analysis was Paired t-test, Pearson's correlation coefficient. The level of vitality and preventive behavior of dementia improved, and fear of dementia level decreased for these elderly using senior citizen centers. Therefore, it is recommended that the integrated ICT based dementia prevention program be utilized in clinical settings to prevent dementia among senior citizens using senior centers.

최근 들어 인터넷사업자들이 웹상에서 제공하는 새로운 서비스가 각국의 개인정보보호 법제에 저촉되는 사례가 늘고 있다 인터넷사업자들이 국경을 넘어 정보를 수집하고 이를 가공처리, 저장하는 과정에서 본인의 동의를 얻지 않거나 개인정보를 익명처리하지 않은 것이 주로 문제가 되고 있다. 본고는 국제적으로 서비스를 하고 있는 대형 인터넷사업자가 프라이버시 침해 혐의를 받고 있는 사례를 알아보고, 무엇이 문제가 되는지 쟁점을 검토하였다. 특히 현지 감독당국이 글로벌 인터넷사업자의 위법사실을 적발하였더라도 해당 사업자가 대리인이나 분신 도구를 통하여 행동한 사실이 없으면 본사에 제게를 가할 수 없는 실정이다. 사이버공간에서는 실제 위반행위자가 없더라도 중대한 개인정보를 침해하는 결과를 가져온다면 영화 <아바타>에서와 같은 해결방법을 모색해볼 수 있다. 아바타는 독자적인 사고나 판단능력이 전혀 없지만, 나비족이 사는 낙원이 지구인에 의하여 파괴될 수 있는 상황에서 아바타와 이를 조종하는 사람들이 한 몸이 되어 나비족과 힘을 합쳐 아름다운 낙원을 지켜낸다. 즉, 인터넷사업자가 국내 실재하지 않더라도 그의 활동결과로 볼 수 있는 침해행위가 발생하고, 그 결과 회복할 수 없는 피해가 발생할 우려가 있으며, 본인과 아바타를 한 몸으로 볼 수 있다면 아바타를 통해 위법행위를 저지른 본사의 책임자를 처벌할 수 있어야 한다. 만일 그 책임자를 특정할 수 없더라도 그의 감독책임이 있는 본사 법인에 책임을 물을 수 있다고 본다. 만일 법원에서 이러한 '아바타 이론'을 수용한다면 국내에서도 외국 본사에 벌금을 과하는 등 처벌이 가능할 것이다. 다만, 해당 인터넷사업자의 반발도 만만치 않을 것이므로 주요국 개인정보 감독기구는 수사정보를 교환하는 등 국제적으로 긴밀한 협조체제를 갖출 필요가 있다.

Despite previous literatures suggesting the co-occurrence of substance abuse and behavioral addiction, their relationship has not been systematically explored. Especially, college students are a high risk group for alcohol use and gambling activities and they have various psychosocial problems due to addictive behaviors. This study aimed to empirically examine that drinking problems predict gambling problems among college students. A total of 455 college students who experienced drinking and gambling completed a survey. Logistic regression analysis were performed. After adjusting for demographics and family related variables, drinking problems predicted the occurrence of problem gambling. Implications for social work practice, policy planning and research area on addiction are discussed.

Anomaly detection techniques have teen devised to address the limitations of misuse detection approach for intrusion detection. An HMM is a useful tool to model sequence information whose generation mechanism is not observable and is an optimal modeling technique to minimize false-positive error and to maximize detection rate, However, HMM has the short-coming of login training time. This paper proposes an effective HMM-based IDS that improves the modeling time and performance by only considering the events of privilege flows based on the domain knowledge of attacks. Experimental results show that training with the proposed method is significantly faster than the conventional method trained with all data, as well as no loss of recognition performance.

임베디드 소프트웨어의 적용영역이 확장됨에 따라 학계와 업계에서 임베디드 소프트웨어 개발 기술에 대한 관심이 고조되고 있다. UML 2.0은 산업체에서 많이 사용되는 모델링 언어로, 그 동안 현장에서는 주로 상태머신 다이어그램(State Machine Diagrams)을 사용하여 임베디드 소프트웨어의 동적 행위를 모델링하여 왔다. 그러나 모델러는 상태머신 다이어그램보다 시퀀스 다이어그램(Sequence Diagrams)을 선호하는데, 이는 시퀀스 다이어그램을 사용하는 것이 직관적이고 정확한 행위 모델을 개발할 수 있기 때문이다. UML 2.0이 최근 다양한 모델링 요소를 반영하도록 확장되었음에도 불구하고, 시퀀스 다이어그램을 사용하여 임베디드 소프트웨어를 모델링을 하기에는 아직 부족한 점이 있다. 이를 보완하고, 임베디드 소프트웨어를 더욱 잘 디자인하기 위하여 예외 상황과 인터럽트를 처리할 수 있는 방법을 제안한다.
