Purpose: In Korea, the frequency and frequency of earthquakes are increasing every year. Therefore, the purpose of this study was to compare and analyze the characteristics and examples of earthquakes in Korea and Japan, and to propose improvements to the earthquake prevention policy in Korea. Method: In this study, we investigate and evaluate Japan's response in two cases: the Kobe earthquake and the East Japan earthquake. After surveying and evaluating the nation's countermeasures in the two events, Gyeongju and Pohang, they were compared. Result: When comparing recovery systems in Korea and Japan, there were significant differences in plans for restoration of road transport networks, regional disaster prevention plans, and the introduction of Conclusion: considering the physical distance between Korea's earthquake-prone areas and the capital, the government should quickly come up with countermeasures to ensure that immediate earthquake response in the region is enhanced through the detailed establishment of the Functional Continuity Plan (COOP), and that administrative functions will function normally in the event of a disaster through the introduction of the administrative BCP concept.

본 연구에서는 여성복지정책 개념이 갖는 지향성에 따라 노무현 정부 여성복지정책과 김대중 정부 여성복지정책을 비교함으로써 노무현 정부 여성복지정책의 성격 규명을 시도하였다. 부녀복지정책에서 여성복지정책으로 개념이 진일보한 1990년대 이후 여성복지정책은 일반 여성을 대상으로 한 정책이라는 막연한 이미지 전달을 시도하였다. 그러나 이같은 여성복지정책 개념은 여성복지정책이 추구하는 사회적 기능의 회복, 인간다운 삶 등이 무엇을 의미하는지 추상적인 나열을 하는 데 그침으로써 성차별 문제를 희석시키는 한계를 보인다. 따라서 김대중 정부 이후 대중적 차원에서 자리매김을 확고히해 가고 있는 여성복지정책의 성격이 좁은 의미에서 복지 문제와 넓은 의미에서 성차별 문제 중 어느쪽에 비중을 두면서 변화해 가고 있는지 혹은 변화해 가야 하는지 등에 대만 분석과 전망을 제대로 제시할 수 없는 제한점을 갖는다. 따라서 본 연구에서는 사회복지정책의 한 영역으로서 '여성복지'를 보는 여성복지정책과 '여성정책'의 한 영역으로서 '여성복지'를 보는 여성복지정책의 차원에서 김대중 정부와 노무현 정부 여성복지정책에 대한 논의를 전개하였다. 김대중 정부 출범 이후 여성복지정책의 변화 양상은 어떠한가? 여성복지정책과 여성복지정책 중 어떤 차원으로의 변화가 두드러진다고 볼 수 있나? 김대중 정부 여성복지정책 기조가 노무현 정부에서 계승되는 양상은 어떠한가? 노무현 정부 여성복지정책 기조는 여성복지정책과 여성복지정책 중 어느 것이 될 것인가? 김대중 정부 출범 이후 사회보험을 중심으로 일어난 변화는 여성복지정책이 전통적인 부녀복지정책 개념에서 탈피하는 양상을 잘 보여주고 있다고 알 수 있다. 또한 여성의 소득 수준 향상 등 여성복지정책적 측면에서 변화를 관찰할 수 있다. 그러나 여성복지정책적 성격을 드러낼 만큼 여성복지정책이 성차별 문제 해소에 중점을 두었다고 보기는 어렵다. 게다가 공공부조에서는 성차별 문제나 복지 문제 중 어느 것에 초점을 둔 정책 방향의 일관성을 발견하기 힘들다. 대통령 공약 사항을 중심으로 살펴본 노무현 정부 여성복지정책은 사회보험 대상자 확대라는 측면에서 여성복지정책적 차원의 단초를 보이고 있으니, 정색 기조는 김대중 정부의 여성복지정책 흐름을 계승하고 있다. 그러나 노무현 정부 출범 이후 관찰할 수 있는 정색 환경의 변화로서 여성부 기능 강화와 급격한 인구학적 변동을 고려할 때 정책 추진 주체 변화를 전제로 한 여성복지정책 강화를 예측해 볼 수 있다.

As the distribution rate of a smart phone which can actualize even augmented reality is getting higher, the application scope of a smart phone is sharply increasing. However, in spite of various functions of it, there is still lack of learning app. Mobile equipments can bring no spatial-temporal restriction of learning to a learner, but they can tempt a learner into inappropriate spaces. In this sense, learning app is necessarily needed to motivate and keep learner's inner desire. This thesis suggested considerations when learning mobile app is designed by analyzing motivation strategy of ARCS Theory and UI of web based contents. Also, a design method of mobile learning app was suggested based on a procedural model of mobile learning app adapting ARCS Theory.

Recently, we developed a new subway train with many cooperative companies. The main controller of the subway train is Control and Monitoring System (TCMS), so we conducted requirement analysis of TCMS considering system performance, easy maintenance and service oriented flexibility. Hence, we adopted new bus architecture and QNX as a Real-time Operating System (RTOS) and developed hardware systems. The functions of TCMS are employed into two computers, service computer and control/monitor computer, to increase on their performance and to yield easy maintenance and to satisfy customer needs. The TCMS controls and monitors control devices equipped in the train through various protocols which are implemented in hardware. In order to evaluate the performance of the system and to satisfy reliability, various experiments including EMC/ECI were performed. Now the TCMS is installed on the newly developed train and is under performance evaluation through test driving.

This paper proposes a mutual identification and session key exchange scheme in secure vehicular communication based on the group signature. In VANETs, security requirements such as authentication, conditional privacy, non-repudiation, and confidentiality are required to satisfy various vehicular applications. However, existing VANET security methods based on the group signature do not support a mutual identification and session key exchange for data confidentiality. The proposed scheme allows only one credential to authenticate ephemeral Diffie-Hellman parameters generated every key exchange session. Our scheme provides a robust key exchange and reduces storage and communication overhead. The proposed scheme also satisfies security requirements for various application services in VANETs.
