최근 해양 분야에서는 해상과 육상의 다양한 데이터를 통합, 활용하여 해상에서의 선박의 안전 운항, 해양 환경 및 자원의 보호 등의 활동에 필요한 정보를 적시에 제공하는 정보 서비스 체계로 e-Navigation에 대한 관심이 높아지고 있다. 국제해사기구(IMO)를 비롯한 해양 분야 국제기구 등은 e-Navigation을 위한 정책, 표준, 관련 기술 및 시스템 개발 등 e-Navigation을 주도하기 위한 많은 노력을 기울이고 있다. UN산하 해사안전 분야 전문기구인 국제해사기구(IMO)는 인적과실에 의한 해양사고를 줄이기 위해 2006년 e-Navigation 도입을 결정, 2018년부터 시행하기 위해 국제협약 제 개정 등을 추진하고 있다. 해양수산부는 국제해상안전 규제동향에 선제적으로 대응함으로써 해양안전을 강화하는 한편, 관련 분야 신산업 육성과 일자리 창출 등을 목표로 하는 "한국형 e-Navigation 대응전략"을 발표하였다. 항로표지는 해상에서의 안전한 활동을 지원하는 필수 시설로써 e-Navigation 시스템의 중요한 운영자원으로 활용될 예정이며 이에 국내에서도 e-Navigation 시스템 운영을 위한 항로표지시설에 대한 기술 개발이 절실한 실정이다. 이러한 항로표지를 이용한 한국형 e-Navigation 운영을 위한 발전 방안에 대하여 기술하였다.

NAT-PT는 IETF의 NGTrans WG에서 표준화한 IPv4/IPv6 변환기술 중 하나로서 IPv4/IPv6 헤더 변환기술(IPv4/IPv6 header translation)을 적용한 변환 메커니즘의 대표적인 사례로 꼽힌다. NAT-PT 변환기술은 그 이름에서 유추할 수 있듯이 NAT 기술에 기반을 두고 있는데, 이러한 연유로 NAT가 가지고 있는 여러 장. 단점을 그대로 계승하고 있다. 따라서 이러한 NAT-PT 변환기술의 태생적인 제약점은 NAT-PT가 standard track RFC임에도 불구하고 이 기술의 사용에 대한 갖가지 논란을 불러 일으키는 근본적인 이유가 되어 왔다. NGTrans WG의 종료 후 새로 결성된 v6ops WG에서는 추가적인 변환기술에 대한 작업보다 IPv6 도입을 위한 시나리오 작업에 중점을 두고 있는데, 이 시나리오에 사용될 변환기술에 대한 논의가 진행되면서 자연스럽게 NAT-PT의 사용에 대한 문제점이 제기되었다. NAT-PT 기술의 향후 진로에 대한 의견은 결국 이 기술의 적용성에 대한 문서를 정리하여 권고안을 만들자는 쪽으로 모아졌고, NAT-PT applicability 저자그룹이 결성되어 지난 57차 IETF 미팅때 첫번째 버전의 문서가 제출되었다. 본 고에서는 이 NAT-PT applicability 00 버전의 문서를 중심으로 NAT-PT 기술의 적용성과 문제점 등을 분석할 것이다.

Beyond the digital world from the analog age, the contents are very easily copied under the illegal conditions and these are rapidly distributed by the information super highway. The increase of ilegal usage and conflict in digital content market would diminish motivation of creators for their work, furthermore break down digital content market on cyberspace. Watermarking technology support to the legal users by the protection technique based chi the digital content copyright protection method(DRM). Most of previous digital watermarking have embeded to the content. In this paper, we have researched the standardization of digital rights management and developed more efficient watermark embedding method.

The customer cabling systems play an important role in the telecommunication networks as an distribution network facilities between the exchange and customer premises. The present standards for domestic customer cabling systems are insufficient for supporting high speed multimedia services. In this paper, the status of the related international standardization and technical standards are investigated in order to enhance current customer cabling facilities in Korea. This paper analyzes the problems in the current technical standards and suggests how to improve technical standards.

As market expansion and demand for smart phone have increased, the wireless data trafic is rapidly growing now. To solve this problem, common carriers in Korea distribute the trafic over Wi-Fi. Smart phones have multi interfaces such as 3G radio, Wi-Fi, Bluetooth, and etc and can utilize them. However these interfaces support seamless handover between not different interfaces but same interfaces, so that users couldn't be supported continuity for handover. In this paper, we describe the Media Independent Handover(MIH) services that is proposed by IEEE 802.21. The standard enhance the handovers across heterogeneous access networks and to optimize the service continuity during handovers.

Recently, financial institutes and industrial companies are adopted to security token such as OTP, smart card, and USB authentication token and so on for secure system management and user authentication. However, some research institutes have been introduced security weaknesses and problems in security tokens. Therefore, in this paper, we analyses of security functions and security requirements in security token performed by analyses of standardization documents, trends, security problems, attack methods for security tokens. Finally, we propose a CC v.3.1 based security token protection profile.

Existent public key certificates provide authentication information through some information on user\`s public key. However, an attribute certificate which stores and manage user\`s attribute information, provides various privilege information such as position, privilege and role. In recent, international organizations establishes standards on attribute certificate, and the researches and developments on attribute certificate have been widely made. In addition it may be expected to be used many real application area requiring for authorization information as well as authentication information. Therefore, this paper considers background and standardization trends of attribute certificate and describes the profile and related techniques of attribute certificate currently established by IETF. In addition, it introduces and access control system using attribute certificate and specifies applications of attribute certificate.

Objectives : Moxibustion-related standards have been established by organizations such as the International Organization for Standardization (ISO) and the Korean Standards Association (KSA), among others. Methods : We summarized moxibustion-related standards that have been published by ISO and KSA. Results : Technical Committees 249 (ISO/TC 249), which was established in 2009, has been established moxibustion devices standards in working group (WG) 4. International standards have been established for moxibustion devices, smokeless moxibustion devices, moxa floss quality, and electric heating moxibustion equipment. Work on international standards for infrared moxibustion-like instruments and moxibustion device terminology is currently in progress. Conclusions : Korea has taken a central role establishing international standards for a wide range of moxibustion devices, supported by fundamental research data in this field. To continue its influence in establishing these international standards, further studies providing the basis for moxibustion device standardization are required.

Since the Korean government has decided to apply the policy of BIM (Building Information Modeling) to the entire construction industry, it has experienced a positive trend in adoption and utilization. BIM can reduce workloads by building model objects into libraries that conform to standards and enable consistent quality, data integrity, and compatibility. In the domestic architecture, civil engineering, and the overseas landscape architecture sectors, many BIM library standardization studies have been conducted, and guidelines have been established based on them. Currently, basic research and attempts to introduce BIM are being made in Korean landscape architecture field, but the diffusion has been delayed due to difficulties in application. This can be addressed by enhancing the efficiency of BIM work using standardized libraries. Therefore, this study aims to provide a starting point for discussions and present a classification system for objects and attribute information that can be referred to when creating landscape libraries in practice. The standardization of landscape BIM library was explored from two directions: object classification and attribute information items. First, the Korean construction information classification system, product inventory classification system, landscape design and construction standards, and BIM object classification of the NLA (Norwegian Association of Landscape Architects) were referred to classify landscape objects. As a result, the objects were divided into 12 subcategories, including 'trees', 'shrubs', 'ground cover and others', 'outdoor installation', 'outdoor lighting facility', 'stairs and ramp', 'outdoor wall', 'outdoor structure', 'pavement', 'curb', 'irrigation', and 'drainage' under five major categories: 'landscape plant', 'landscape facility', 'landscape structure', 'landscape pavement', and 'irrigation and drainage'. Next, the attribute information for the objects was extracted and structured. To do this, the common attribute information items of the KBIMS (Korean BIM Standard) were included, and the object attribute information items that vary according to the type of objects were included by referring to the PDT (Product Data Template) of the LI (UK Landscape Institute). As a result, the common attributes included information on 'identification', 'distribution', 'classification', and 'manufacture and supply' information, while the object attributes included information on 'naming', 'specifications', 'installation or construction', 'performance', 'sustainability', and 'operations and maintenance'. The significance of this study lies in establishing the foundation for the introduction of landscape BIM through the standardization of library objects, which will enhance the efficiency of modeling tasks and improve the data consistency of BIM models across various disciplines in the construction industry.
