According to IT technology has evolved, smart phone rapidly propagates for mobility. A smart phone user acquires useful information, but attackers generate various damage. For example, an attacker must distribute to expose the privacy of others. To solve this problem, various information security products are being developed. In addition, information security has been strengthened. In this paper, we propose a scheme for secure use of smart phone. For development of secure smart phone, the development processes should be secure. In addition, we propose an information security production certification system for secure smart phone security.

Validation of viral safety is essential in ensuring the safety of mammalian cell culture-derived biopharmaceuticals, because numerous adventitious viruses have been contaminated during the manufacture of the products. Mammalian cells are highly susceptible to minute virus of mice(MVM), and there are several reports of MVM contamination during the manufacture of biopharmaceuticals. In order to establish the validation system for the MVM safety, a real-time PCR method was developed for quantitative detection of MVM in cell lines, raw materials, manufacturing processes, and final products as well as MVM clearance validation. Specific primers for amplification of MVM DNA was selected, and MVM DNA was quantified by use of SYBR Green I. The sensitivity of the assay was calculated to be $6{\times}10^{-2}TCID_{50}/mL$. The real-time PCR method was proven to be reproducible and very specific to MVM. The established real-time PCR assay was successfully applied to the validation of Chinese hamster ovary (CHO) cell artificially infected with MVM. MVM DNA could be Quantified in CHO cell as well as culture supernatant. When the real-time PCR assay was applied to the validation of virus removal during a virus filtration process, the result was similar to that of virus infectivity assay. Therefore, it was concluded that this rapid, specific, sensitive, and robust assay could replace infectivity assay for detection and clearance validation of MVM.

There are about 17,531 agricultural small dams and reservoirs in Korea. Ninety five percent of the small dams were constructed by earthfill and they were suffered severe damages or expected to repairs or rehabilitation. Therefore dams are evaluated and are identified their problems. Small Dams should be repaired before too late. Small dam safety evaluation is required to guarantee the proper functions of the existing agricultural dams and reservoirs in time and to minimize the damage.

계란으로 인한 살모넬라 식중독은 전 세계적으로 문제가 대두되고 있으며, 이를 해결하기 위하여 세계 각국은 대책을 강구하고 있다. 영국에서는 일찍이 라이언스 퀄리티 시스템을 도입하여 품질 보증된 안전한 계란을 생산하는 시스템을 구축하였으며, 미국과 일본 등도 각고의 노력을 기울이고 있지만, 아직 우리는 필요성만 인지하고 있을 뿐 구체적 대안을 제시하지 못하고 있는 실정이다. 열악한 환경에서 강한 면역체계를 갖춘 30대 이상의 건강한 사람의 경우는, 현재와 같은 시스템으로도 별반 문제가 없다 하더라도, 면역력이 떨어진 고령자나 어린이 등에게 있어서는 향후 치명적인 결과를 초래하여, 양계산업 기반이 흔들릴 소지가 있으므로, 미리 이에 대한 대비책을 강구하여야 한다. 이를 위해 도입된 시스템이 HACCP 시스템이다. 양계의 특성상 완전히 무균화된 생산 공정을 요구 할 수는 없다. 하지만 이의 목적은 단 하나다. 최종 소비자에게 이르렀을때는 안전한 계란이 되어야 한다는 것이다. 이 목적을 달성하기 위해서 사람, 설비, 방법 등을 어떻게 할 것이며 관리 감독할 것인가 절차를 명문화하고 이를 준수하고 개선하고 시정 조취를 취하느냐 하는 것을 표준화 한 시스템이다. 각론에서는 실행에 여러 어려움이 있겠지만, 안전한 계란을 생산하기 위한 목적을 달성하는 최적의 방법을 찾아가는 것이라 할 수 있으며, 이런 명제 하에 HACCP를 도입한다고 할 수 있으며, 이에 조금이라도 일조 하고자 IPPS JAPAN 2001에 소개된 농장에서 식탁 까지를 기본으로 한 양계장 에서의 HACCP 방식 이란 논문을 번역하게 되었다. 아직 양계 분야에서 어떻게 도입해야 할지 막막한 상황이므로 좋은 참고가 되었으면 하는 바램이며, 지면관계상 세심한 부분까지 거론되지 않은 부분도 있을 수 있으나 이를 실행함에 있어서 상호 충분한 토의를 거쳐 제도로 정착될 수 있도록 업계 여러분과 이에 대해 많은 협의를 할 수 있었으면 한다.

Areas of concentrations that can be exploited at all times, such as gas reservoirs in crude oil tanks, are called zero zones. In order to use various equipment in Zone 0, an intrinsically safe certification must be obtained that can guarantee that sparks will not occur in nature. Most devices that acquire intrinsic safety certification are mostly simple single-component devices or devices. In this study, it was a very difficult process because we intend to acquire the intrinsic safety certification of an electronic circuit including an ultrasonic generator and a microcontroller in which hundreds of components are mounted on a PCB substrate. Through this study, we have been able to understand how to design a circuit for intricate intrinsic safety certification. and Using the results of this study, it will be easier to design intrinsically safe circuits when trying to develop a circuit that can obtain intrinsic safety certification.

The aircraft system safety assessment, which is emphasized in the development and certification of aircraft, is a systematic and comprehensive evaluation process to determine that all relevant failure conditions have been identified and that all significant combinations of failures cannot result in unacceptable hazards. As the aircraft systems become more complex and require integrated function and performance, proper safety objectives must be established and appropriate assessments are need to be accompanied. This paper has prepared to propose the efficient probabilistic analysis of failure data to evaluate the risk level over the entire aircraft lifecycle through the safety assessment and to review the considerations for aircraft certification and safety improvement.

As the importance of software in various industry areas has been increased, the number of accidents related to software safety are growing up. The key industries such as railroads, aviation and medicine, recommend IEC 61508 and international safety standards for their own to achieve functional safety and reduce the issues caused by that. For equipment of ship navigation, there are not any particular standards or guidance which Korean users can introduce as considering software functional safety. This article defines the procedure and outcomes of the risk analysis in order to secure software functional safety in marine navigational equipment and applies them to an echo sounder as a case study.

As the applications within Internet becoming more extensive, the security issues of those applications are appearing to be the most important concern. We have to be sure if all elements of the system are robust and perform well. Even if some small part of the system is vulnerable, it might cause the total system crash-down. Therefore, every part of the system should be thoroughly designed and mutually coordinated in order to support overall security of the system. In this paper, we propose new technique which uses the fingerprint features in order to generate one time passwords(OTPs). Fingerprint is considered to be one of the powerful personal authentication factors and it can be used for generating variable passwords for one time use. Also we performed a simulation for proposed password generation method.
