In this work we deal with the problem of how to squeeze multiple ciphertexts without losing original message information. To do so, we formalize the notion of decomposability for public-key encryption and investigate why adding decomposability is challenging. We construct an ElGamal encryption scheme over extension fields, and show that it supports the efficient decomposition. We then analyze security of our scheme under the standard DDH assumption, and evaluate the performance of our construction.

Walking passenger injury accidents in and around stations have increased in recent years, and passengers are now more aware of being able to claim compensation for such accidents. Therefore, it is anticipated that station managers and owners will need to take measures to improve the condition of walking areas so that performance objectives are met an the compensation paid for passenger accidents is limited. The aim of this study covers the following: accidents statics and contributory factors, station flooring and footway material, guidance for flooring, and test methods for slipperiness and surface profile.

본 논문에서는 아동 교육시 활용할 실감형 교육 콘텐츠(Realistic Educational Content)를 구축하여 수업활동시 활용했을 때의 학습향상 효과를 살펴 본 결과 시각 청각을 이용한 콘텐츠보다, 후각을 추가하여 수업을 진행하였을 때 학생들의 집중과 수업에 대한 몰입감이 높아진 것을 실험결과 알 수 있었다.
