  • 요즈음 교통사고를 줄이기 위하여 IT 기술을 이용한 교통사고 연구가 많이 진행되고 있다. 특히, 고속도로에서 교통사고를 예방하기 위해서 눈이나 비가 올 경우에는, 날씨조건을 고려한 최적의 교통속도를 실시간으로 산출해야한다. 본 논문에서는 교통사고를 예방하기 위하여 결빙 구간 및 안개구간 자동 경고 안내 방송 시스템을 웹기반에서 모의실험 하였다. 뿐만 아니라, 퍼지 추론 규칙을 이용하여서, 최악의 날씨 조건에서도 교통사고를 예방 할 수 있도록, 운전자 에게 최적의 교통 안전속도를 실시간으로 운전자에게 알려 주는 모의실험을 개발하였다.

  • Purpose: The purpose of this study is to research to protect to loss of chrome-plating of small arms barrel on high temperature in order to extend its life expectency. Methods: The reason why chrome-plating dropped out is main material is weak from heat. Therfore, to make barrel of small arms have higher heat-resistant property, nitriding for barrel before chrome-plating is needed and test of that barrel was handled to improve it. Results: Nitriding before chrome-plating is useful to protect to chrome-plating loss on high temperature. Conclusion: To protect loss of chome-plating of small arms barrel during on firing, pre-nitriding on barrel is effective finally it leads to extend to barrel's life expectency.

  • Recently, a cryptographic construct, called fuzzy vault, has been proposed for crypto-biometric systems, and some implementations for fingerprint have been reported to protect the stored fingerprint template by hiding the fingerprint features. In this paper, we implement the fuzzy fingerprint vault, combining fingerprint verification and fuzzy vault scheme to protect fingerprint templates. To implement the fuzzy fingerprint vault as a complete system, we have to consider several practical issues such as automatic fingerprint alignment, verification accuracy, execution time, error correcting code, etc. In addition, to protect the fuzzy fingerprint vault from the correlation attack, we propose an approach to insert chaffs in a structured way such that distinguishing the fingerprint minutiae and the chaff points obtained from two applications is computationally hard. Based on the experimental results, we confirm that the proposed approach provides higher security than inserting chaffs randomly without a significant degradation of the verification accuracy, and our implementation can be used for real applications.

  • The purpose of this study is to analyze protection functionality of supermodern fashion which is shown by responding to supermodern environment, where non-spaces increases in the 21st modern city. The theoretical background is drawn for supermodern environment theory. For the study, he researcher used existing study and specialized book and analyzed photograph materials by selecting them in specialized fashion book, internet site and designer's collection. The works from 1995 S/S collection to 2008 S/S collection are analyzed. The result of this study is as follow. First, supermodern design is adopting the shape of high-functional element, electronic device, protective device to protect wearer in non-space. Second, in order to mentally protect individual anonymous leadership of interaction is granted by adopting hood, veil or mask. Third, supermodern design is creating independent and user-based space by shape transformation in change of urban environment. Fourth, in order to protect wearer through camouflage or concealment, camouflage pattern or neutral color are used.

  • 개인 정보 유출로 인한 피해사례가 늘어나면서 사용자 프라이버시 침해에 대한 인식이 높아지고 있다. 그러나 기존의 DRM 시스템은 사용자의 프라이버시 보호가 저작권을 보호하는데 직접적으로 필요하지 않다는 이유로 사용자의 프라이버시 보호에 대해 고려하지 않았다. 본 논문에서는 DRM에서 사용자 프라이버시 보호 측면이 강조된 라이센스 관리 프로토콜을 제안한다. 제안한 프로토콜은 사용자 식별 정보의 노출을 보호하기 위해 임시 ID와 token을 사용함으로 익명성을 보장하고 ECDH 세션키와 공개키 암호 시스템을 이용하여 메시지를 암호화함으로써 사용자 정보의 유출을 방지하여 사용자의 프라이버시를 보호한다.

  • Any design engineer or coating formulator's primary objective is to protect metals. Large investments in terms of money, time, labour, and other resources are necessary for constructing large-scale machinery and structures. In terms of economy, the structure's lifespan should be as long as feasible to create revenue. It is becoming essential to protect metal substrates from corrosion to prolong the lifespan of such huge structures. One of the most exciting, durable, useful, and effective methods to protect metals from corrosion is the application of corrosion-resistant coating. Graphene is a novel material with a wide range of applications because of its extraordinary features. The use of graphene in coating creates an obstacle and complicates the path for corrosive medium to reach the metal. As the path to the metal elongates, the corrosion medium takes longer to reach the metal. Thus, metal corrosion can be avoided. In this paper, the importance of graphene in coating formulation is discussed, including chemical modifications of graphene, the effect of graphene concentration on corrosion inhibition, and the contact angle of coating. This review also highlights the significance of water-based corrosion-resistant coating for preventing environmental damage.
