In the coming age of information warfare, information security patterns take on a more offensive than defensive stance. It is necessary to develop an active form of offensive approach to security protection in order to guard vital information infrastructures and thwart hackers. Information security products need to support an automatic response facility without human intervention in order to minimize damage to the attacked system and cope with the intrusion immediately. This paper presents an automatic intrusion response model which is developed on a Self-Extension Monitoring. It also proposes an ARTEMIS(Advanced Realtime Emergency Management and Intruder Identification System), which is designed and implemented based on the suggested model. The Self-Extension Monitoring using self-protection and replication minimizes spatial limitations on collection of monitoring information and intruder tracing. It enhances the accuracy of intrusion detection and tracing.

In this study, we investigate on the crystal microstructure and magneto-resistance (MR) change of Bismuth(Bi) thin films for annealing process, in order to apply Bi thin films to the spin electronic devices. As-prepared Bi thin films show the randomly oriented find grains whose size was measured to about 100 nm and the very low MR (4.7 % at room temperature) while careful annealing results in not only grain growth up to ${\sim}2{\mu}m$ but also drastic MR improvement (404 % at room temperature). The drastic change in the MR after applying the annealing process is attributed to the grain growth decreasing grain boundary scattering of electron. Therefore, in this study, we confirm the annealing effect for the grain boundary formation and MR improvement of Bi thin films, and demonstrate the feasibility of spin electronic devices.

The purpose of this study is to examine the application of in-depth interviews in terms of exploration on the basis of the theoretical basis of various aspects of consumer empathy, and the question of whether the consumer can expand to the process of self empathy. Most studies related to consumer empathy divide the responsive dimension of consumer empathy into rational and emotional dimension based on empathy theory, and look at the empathic response perceived by consumers to the stimulus presented from the current point of view. In this study, however, we want to go one step further and confirm that the consumers themselves can ultimately go to the self-empathy stage by forming a creative street of reproduction and redevelopment. As a result of exploratory research through in-depth interviews, it was indirectly confirmed that consumer's empathetic response to specific marketing stimulus exists at the level of creative and self-empathetic as well as the emphasis of previous studies. Based on these findings, this study confirmed that consumer empathetic responses could go beyond a single dimension to form a multidimensional structure and move toward an expanded structure of empathic self-creation. This suggests that consumers' empathic responses should be grasped in terms of continuity of empathic responses rather than explained in a specific dimension. Although this study is meaningful as an early research of exploratory nature, it is necessary to supplement various content validity and refine the research method through subsequent studies. This study is expected to expand the understanding that consumer's empathy can be extended to other people's empathy and to be self-empathy.

Magnetic sensors and actuators have been widely used in industry and medical fields. Integrated systems based on sensors and actuators are defined as mechatronics that is the general combination of mechanics and electronics. Recently, magnetic wireless sensors and actuators have been developed and used at a systematic level. In particular, their mechanisms depend on magnetic, such as magnetic material and physical phenomena. However, their research boundary has not been clear. Researchers talk of magnetic micro-robots, magnetic actuators and sensors. Therefore, a new and correct definition is required. In this study, we introduce the advanced and extended concept of mechatronics, which is a magneto-mechantronics for biomedical and rehabilitation. Among various applications, we focused on wireless pump and sensing system for blood vessel rehabilitation and local motion capture, respectively.

The purpose of this study is to develop a service norm construct influencing behavioral intention in a service purchasing situation and investigate how the construct is related with other constructs in the theory of planned action model. Furthermore, a moderating variable, self-monitoring concept, in the model is considered. As a result, the influence of attitude, subjective norm, and perceived control on behavioral intention were all significant. Other consumers' norm was a significant factor affecting behavioral intention. Service provider norm, however, was not significant. In addition, self-monitoring played a moderating role in the model. The implication of this study is that service company or manager should consider service customer compatibility because focal customers are conscious that they face other customer's response.

소변이 오랜 시간 방광에 머물면 방광염이 생길 가능성도 많고, 또한 방광의 확장으로 방광근육의 손상이 생기기 쉽다. 그러므로 당뇨병환자에서는 혈당조절이나 식이 요법 등의 자기관리가 필요한데, 남성에서는 전립선도 자기관리 항목에 추가하는 것이 좋을 것으로 생각한다.

이진값을 가지는 이진 시스템을 모델화하고 설계하여 구현할 수 있도록 Petri Net의 한 부류인 박스의 마크수가 최대 1인 안전(safe)한 확장된 마크흐름선도(EMFG : Extended Mark Flow Graph)를 재구성하였다. 레벨박스와 펄스박스 및 게이트박스를 하나의 박스로 통일하였으며, 보존아크를 제거하고 서로 상반되는 개념을 가지는 일반아크와 역아크만을 사용하였고, 특히 트랜지션의 출력아크로 새로이 역아크를 도입함으로써 EMFG의 표현을 명확하게 하였다. 또한 EMFG에서 자기루프를 정의하였다. 그리고 이진 시스템을 모델링한 EMFG를 실제회로로 구현하는 방법이 새로이 제시되었다.

XML은 자기 서술적인 표현 언어라는 중요한 장점을 가지고 있기 때문에 인터넷 관련 응용들에서 정보의 표현 및 문서 교환의 표준으로 빠른 속도로 자리잡아 가고 있다. 본 논문에서는 SQL에 XPath 표현 중 일부를 추가하여 SQL을 확장함으로써 XML 문서에 대한 질의를 가능하게 하였고, 또한 SQL의 CRUD(Create, Read. Update, Delete) 기능을 그대로 사용함으로써 XML 문서의 변경이 가능한 XML 질의를 위한 새롭게 확장된 SQL을 제안하였다. 그리고 폭 넓게 사용되고 있는 ORDBMS 환경에서 XML 색인 정보를 자동 생성 관리하는 XML 저장 관리기 및 확장된 SQL 처리기를 설계하고 구현하였다. 본 논문에서 제안하는 확장된 SQL 처리기는 XML 원문 자체의 보관을 원칙으로 하여 완벽한 문서 복구 등에 따르는 부담을 제거하였고, XML 저장 문서에 대한 원본성 및 무결성을 쉽게 유지할 수 있도록 하였으며, 색인 정보를 자동 생성 관리함으로써 파일 처리 시간과 XML 트리 운행 시간 및 XPath 파싱 처리 시간을 줄였다. 또한, “path”라는 키워드를 추가로 관리함으로써 ORDBMS 환경에서 XML 질의를 위한 SQL 변환 과정에서 PATH의 깊이 만큼 조인이 중첩되는 문제를 배제하여 조인이 발생할 가능성을 줄이는 방법을 제시하였다.
