From the hazard which it prepares in the hazards increase which it follows in information demand augmentation of information technical development and the consumer from inside systematizing integrity and solubility of information technological resources. inside against a confidentiality. The control against information and a system and a data outside is demanded. From the dissertation which it sees demand function and the structure which do information technical risk management system development it will be able to manage the danger which it infiltrates with the root which is various overview in hazard necessity it investigated the inside and outside of the country instance in the center and it analyzed. And it plans the dangerous civil official integrated process model ultimately as against a hazards it will be able to prepare in the dictionary in order, it put the place objective which it induces.

There are a lot of on-going researches on various security technologies for guaranteeing the safety of home network systems. Until now, a few security technologies such as device authentication mechanism, user authentication mechanism, access control mechanism and firewall are generally deployed, and they are just simple. However, we need some representation skills in order to efficiently define the home network and describe the security for managing and performing these security mechanisms. So, in this paper, we define the xHDL language to define and describe the security components of home network and analyze the semantics of each components.

급속한 정보기술 및 인터넷의 발달로 인해 네트워크를 통한 정보의 교류가 활발해지고 온라인 뱅킹 등 전자상거래와 관련된 산업의 규모가 커지면서 정보보안과 휴대용이 용이한 스마트카드는 여러 활용분야에서 사용되고 있다. 계속적인 하드웨어 기술의 발전으로 스마트카드의 표준으로 자리 잡고 있는 자바카드는 스마트카드 플랫폼에 자바의 기술을 접목시킨 것으로써 객체지향 중심의 기법으로 보안상 매우 좋은 이점을 지니고 있다. 또한 특성이 다른 하드웨어에서 같은 동작을 할 수 있는 개방형 운영체제를 가짐으로써 다양한 다수의 응용 프로그램을 수용할 수 있는 유연성을 가지게 한다. 본 논문에서는 이러한 자바카드의 특성을 이용하여 하나의 회원 카드로 다수의 사용자가 사용할 수 있는 접근통제가 가능한 회원카드를 설계하였다. 사용자에게 발급된 하나의 카드에 들어있는 정보를 개인이 아닌 다수의 사용자가 서로 다른 PIN을 이용하여 카드 내에 있는 사용자 정보를 접근하여 개인 정보의 확인, 관리내용 업데이트, 내용에 따른 청구를 카드 하나로 가능하게 하였다. 이때 사용자 인증수단으로 사용되는 PIN의 보안성을 높이기 위해 개인별로 고유한 생체인식의 한 구성요소인 서명 데이터를 이용하여 패스워드가 가지는 보안상의 취약요소를 없애 보다 안전한 사용자 인증을 하고자 한다. 이러한 자바카드의 이용기술과 생체인식 및 다중PIN을 이용한 사용자 인증, 파일의 보안 등급의 차등적인 접근권한을 설계하고 마지막으로 비주얼한 응용프로그램을 구현함으로써 카드를 보다 안전하고 편리하게 사용할 수 있기를 기대한다.

Recently, the importance of personal information security has emerged. In particular, the importance of biometrics such as voice recognition, fingerprint recognition, face recognition has been highlighted in various fields such as access control, banking security, personal PC security and so on. But if such conventional security techniques are likely to be recognized by an external factor failure. In contrast, if the vein recognition is impossible to copy and counterfeit. Therefore less likely to fail due to external factors has the advantage. In this paper, propose a preprocessing method to improve on the existing vein pattern recognition with high reliability than existing biometric technologies.

Due to the increase in the demand for anomaly detection according to the ageing of power generation facilities, the need for developing an anomaly detection method that can provide high-reliability turbine blade anomaly detection performance has been continuously raised. Additionally, the false detection results caused by a human error accelerates the increase of the need. In this paper, we propose an anomaly detection technique for turbine blades in power plants using deep neural networks. Experimental results prove that the proposed technique achieves stable anomaly detection performance while minimizing human factor intervention.

A large number of FRP decks are already in service worldwide because the lighter FRP-based bridge decks are ideal for rapid construction to reduce the dead load of superstructures. And the proper design process is demanded for the effective FRP deck application. In this paper, to get the basic prototype of FRP bridge decks, the ratio of individual parameters, which compose the specification of FRP bridge decks, are determined by a finite element analysis. In addition, optimum FRP deck shapes are determined considering complex constraints and material properties of bi-directional characteristics. Upon these results, the prototype of FRP bridge decks is validated.

It is required for enterprises to construct the proper information management system in order to cope with the volatile business situations. The mobile office system is introduced from the needs to provide organization members smart information and mobility. By setting the model, hence, we intend to scrutinize the impact of the task-technology fit model and organizational characteristics of the mobile office system on the job performance. As a result, system quality, information quality and mobility are revealed to affect positively the task-technology fitness and the fitness also affects the job performance positively. Organization characteristics affects the job performance positively through the task-technology fitness, too. Therefore the organization which plans to introduce the mobile office system should consider the task-technology fitness and exert organizational-level efforts to adopt and use the mobile office system in the workplace.

The purpose of this paper is to analyze the influence of marketing capabilities on business performance among SMEs. The results suggest that complexity, trialability, and observability are among the technological factors that have a significant influence on ICT adoption. Research advantage and compatibility do not influence ICT adoption. Meanwhile, organizational factors such as owner/manager knowledge and innovativeness significantly influence ICT adoption among SMEs. Environmental factors such as competitive pressure, institutional intervention contribute significantly to the adoption. Moreover, data analysis reveals that ICT adoption has a positive influence toward SMEs' marketing capabilities. Finally marketing capabilities significantly influence a firm's business performance.

This study analyzes the political and legislative progress that although basic acts to establish an integrated system of cybersecurity are steadily being proposed, they have not been passed as legislative deadlocks under the two major parties. It shall be analyzed through Korea's legislative system, including differences in contents and interests of the disposal act, the timing and cycle of election ect. The study analyzes why the basic cybersecurity law was previously scrapped and faced political gridlock situation by analyzing the differences in the contents and interests of the two major parties, and the timing and cycle of the proposed legislation.
