Security incidents using vulnerabilities in cloud services occur, but it is difficult to collect and analyze traces of incidents in cloud environments with complex and diverse service models. As a result, the importance of cloud forensics research has emerged, and infringement response scenarios must be designed from the perspective of cloud service users (CSUs) and cloud service providers (CSPs) based on representative security threat cases in the public cloud service model. This simulated hacking-based proactive cloud infringement response framework can be used to respond to the cloud service critical resource attack process from the viewpoint of vulnerability detection before cyberattacks occur on the cloud, and can also be expected for data acquisition. Therefore, in this paper, we propose a framework for preventive cloud infringement based on simulated hacking by analyzing and utilizing Cloudfox, a cloud penetration test tool.

A location information used in LBS provides convenience to the user, but service provider can be exploited depending on how much risk you have. Location information can be exploited to track the location of the personal privacy of individuals because of the misuse of location information may violate the user can import a lot of damage. In this paper, we classify the life cycle of location information as collection, use, delivery, storage and destroy and analyze the factors the privacy is violated. Furthermore, we analyze information security mechanism is classified as operation mechanism and policy/management mechanism and propose a security solutions of all phase in life cycle.

As the development as the IT society accelerates, the frequency of terrorism from malignant codes and other cyber crimes is increasing. Malignant codes show various forms of attack according to the intentions of the attacker, and leaves behind digital evidences, not analog evidences when damages occur. Digital forensic, the procedure of collecting and analyzing digital evidence is one of the main factors that must be carried out when damages from malignant codes arise. However, there are the difficulties of not being able to preserve the integrity and authenticity in the procedure of coping witht infringements, which must be maintained in the digital forensic procedure. To complement such problems, this paper suggests the method of applying forensic by identifying the malignant code infringement incidents according to the type of damages.

The purpose of this study was to examine the effects of a script intervention based on multimedia on the verbal and behavioral self-advocacy skill of elementary school students with disabilities. A multiple probe baseline design across subjects had been used with 4 students with intellectual disabilities. The results showed all participants showed significant increase of verbal and behavioral self-advocacy performance in asking for help, expressing one's opinions, and coping with violations, and the effects were maintained. The intervention was more effective for verbal self-advocacy than behavioral. Some suggestions for future study are discussed.

In this treatise I have advanced a theory to regulate legal problems rationally arising from a right to a view and I have checked some precedents dealing with the temporary injunction, compensation for damage and the demolition of a house(mainly apartment) owing to an infringement of a right to a view. Relating to an infringement of a right to a view, there are more lawsuits which are instituted together with an infringement of a right to enjoy sunshine than lawsuits related only to the right to a view. In the cases of an infringement of a right to a view connects with educational or religious environment, the court made it a decision that the construction is prohibited from constructing more than a certain-story building to protect a right to a view. Plaintiffs won a case their suit in the original judgement regarding a claim for damages owing to an infringement of a right to a view, but the Supreme Court reversed the decision of a lower court. The right to a sky view should not be infringed in case of a dwelling house which is not built for the purpose of business or a view.

Nowadays, social networking sites (SNSs), such as Twitter, LinkedIn, and Tumblr, are coming into the forefront, due to the growth in the number of users. While users voluntarily provide their information in SNSs, privacy leakages resulting from the use of SNSs is becoming a problem owing to the evolution of large data processing techniques and the raising awareness of privacy. In order to solve this problem, the studies on protecting privacy on SNSs, based on graph and machine learning, have been conducted. However, examples of privacy leakages resulting from the advent of a new SNS are consistently being uncovered. In this paper, we propose a technique enabling a user to detect privacy leakages beforehand in the case where the service provider or third-party application developer threatens the SNS user's privacy maliciously.

With diffusion of Smart Work, a problem has been raised that Smart Work makes the boundary between work and nonwork blur, and may cause technostress. In order to find out whether Smart work copes with techno-invasion stress in work domain, we need to understand the precedence factors influencing on job satisfaction and the role of boundary management strategy which Smart Workers actively choose. This paper developed a research model containing a causal relationship among four factors, nonwork-to-work interference, job autonomy, job commitment, and job satisfaction, and the moderation effect of boundary management strategy. The findings show that overall hypotheses were accepted based on the pooled data, but three hypotheses test on job satisfaction by boundary management strategy type differed. These results suggest that in accordance with the boundary management strategy of Smart Work users, different change management need to be prepared.

인터넷 환경의 발달에 의해서 사용자의 편리성은 증가하였지만, 사용자의 프라이버시가 노출되는 위험 또한 증가하였다. 그 중에서 사용자의 신원이 인증 절차에서 서비스 제공자에게 노출됨으로 사용자 프라이버시 침해 문제가 발생할 수있는데 , 본 논문에서는 인증 절차시 사용자의 익명성을 제공하고 유사시 제 3의 기관과 협력해서 익명성을 제거할 수 있는 새로운 신원위탁방식을 제안한다.
