  • High-quality digital broadcasting contents are susceptible to illegal copy and unauthorized redistribution, which makes broadcasters difficult to protect valuable media assets. So, broadcasters and content providers need the technology for copyright protection of professional digital content. Digital watermarking technology is one of the most actively developed solutions for the copyright protection. This paper suggests the requirements of watermarking technology in DTV(Digital TV) environment for copyright protection and shows the developed real-time watermark embedding/detecting system for HD(High Definition)/SD(Standard Definition) video and experimental results of the system against watermark attack tests. Our watermarking system meets the watermarking requirements of invisibility, robustness and security of DTV environment.

  • Objectives : The purpose of the study was to examine the ethical requirements for the protection of human subjects in the publication guidelines of dental health journals. Methods : The guidelines of 27 dental health journals were reviewed to determine ethical standards alone, with Helsinki Declaration, by an institutional review board (IRB), informed consent, protection of subject privacy and confidentiality, and no conflicts of interest. Results : 1. Dentistry journals listed on National Research Foundation of Korea had a conflict of interest disclosure provisions of the contribution(76.9%) and the IRB approval(61.5%). 2. Half of the dental health journals were not listed on National Research Foundation of Korea Society but they agreed the advance posting provisions. 3. Dental hygiene journals provide 100% of ethics alone and receive 75% of IRB in the papers. 4. Dental health and dental hygiene journals have conflicts of interest disclosure regulations(59.2%) and IRB approval(51.8%). 5. There existed statistically significant differences between the dental health journals whether they were listed on the human subjects and ethical standards for protection in National Research Foundation of Korea or not. Conclusions : While the publication guidelines of dental health journals have followed to a greater extent in recent years, there is still a need for further instructions to ensure that the authors satisfy all ethical requirements in conducting research on human subjects. IRB approval for dental journals must be standardized and reinforced reflecting the characteristics of each journals. The researchers should obey the code of ethics suitable for education and the editors must review the paper continuously.

  • 원자력 발전소의 디지털 제어 시스템에 적용되는 소프트웨어는 안전성이 중요시되는 safety-critical 소프트웨어로, 충분한 수준의 안전성을 보장하기 위해서 여러 기법들이 적용되고 있다. 특히, 정형명세 기법은 개발의 초기 단계에서 소프트웨어 요구 사항들을 명확하고 완전하게 명세 하도록 유도함으로써 안전성을 크게 향상시킬 수 있는 기법으로 인정받고 있다. 본 논문에서는 원자력 발전소 디지털 제어 시스템 소프트웨어의 요구 사항 명세에 적합하도록 개발된 정형명세 기법인 NuSCR을 논의한다. 또한, 개발된 NuSCR의 적용성을 검토하기 위해, 현재 KNICS 사업단에서 개발중인 발전소보호계통 소프트웨어의 요구사항을 정형 명세 한 경험을 소개하고 있다. 또한, 원자력 도매인에 특화된 정형명세 기법인 NuSCR의 우수성도 실례를 들어 설명하고 있다.

  • This paper first outlines the technology used in Power Line Communications(PLC) systems, and the political support being offered to the technology, from the point of view of its effect on electromagnetic compatibility (EMC). The radio spectrum needs protection from other interferers, and there is a regime in place to provide this interference avoidance/mitigation. Nevertheless, PLC has several features that mean that it is capable of creating such interference. These features are discussed, and some published field trial results are reviewed. Difficulties in achieving compatibility between the requirements for radio protection and the requirements for operation of the PLC system mean that there is no consensus as yet as to how PLC system components can be made compliant with EMC requirements. It is concluded that there is little prospect of an accommodation between the competing demands, so that if PLC is to become widespread it will be at the expense of the radio environment.

  • UAE(United Arab Emirates) 원전(원자력발전소)의 수출을 목적으로 UAE, 미국, 일본, 한국의 원전 화재방호규정을 상호 비교 검토하였다. UAE를 포함하여 미국, 일본의 원전 화재방호규정은 화재하중에 따른 화재위험도 분석결과에 따라 소화설비를 설치하도록 규정하고 있다. 반면, 우리나라는 소방관계법에서 원전을 발전시설로 구분하고 있으나, 원자력법에서는 원자로 및 관계시설로 분류하고 있고, 각 법률간 화재방호 설계기준도 상이하다. 앞으로 우리나라가 원전 수출국의 지위를 계속적인 유지하기 위해서는 화재 위험도분석의 결과가 설계에 반영될 수 있어야 한다. 결론으로, 국내 소방관계법이 원전의 특수성을 반영하기 위해서는 소방시설공사업법 시행령 제2조 2항의 성능위주설계를 해야 할 특정소방대상물에 원전이 추가되어야 함을 제안하였다.

  • In order to ensure reliability the high-level automated driving such as Advanced Driver Assistance System (ADAS) and universal robot taxi provided by autonomous driving systems, the operation with high integrity must be generated within the defined Operation Design Domain (ODD). For this, the position and posture accuracy requirements of autonomous driving systems based on the safety driving requirements for autonomous vehicles and domestic road geometry standard are necessarily demanded. This paper presents localization requirements for safe road driving of autonomous ground vehicles based on the requirements of the positioning system installed on autonomous vehicle systems, the domestic road geometry standard and the dimensions of the vehicle to be designed. Based on this, 4 Protection Levels (PLs) such as longitudinal, lateral, vertical PLs, and attitude PL are calculated. The calculated results reveal that the PLs are more strict to urban roads than highways. The defined requirements can be used as a basis for guaranteeing the minimum reliability of the designed autonomous driving system on roads.

  • 차세대 자동차 기술 중의 하나인 V2V 통신은 차량 간에 통신할 때 사용되는 기법으로 차세대 ITS의 핵심기술이다. 기존 V2V 통신 인증 서비스 구조를 살펴보면 프라이버시 보호에 대한 보안 요구사항을 충족시키기 위해 가명 인증서를 사용한다. 가명 인증서를 사용하기 위해 발급 및 관리하는 기관이 필요하고 한번 발급할 때 여러 개의 인증서를 발급하기 때문에 시간이 많이 소요된다. 본 논문에서는 가명 인증서를 사용하지 않고 프라이버시 보호에 대한 보안 요구사항을 충족시키기 위해 차량 ID를 활용한 기법을 제시하고자 한다.
