전기통신설비에 대한 기술기준은 통신망 운용에 대한 정책이기도 하며 또한 통신사업자에 대한 관리체계이기도 하다. 기술기준은 전기통신망에 대한 법령으로서 통신망의 총체적인 설계 목표가 된다. 기술기준으로 다루어야 할 범위와 기준의 수준 등은 통신망 환경에 따라 다르게 운용되며, 권고적 성격을 띠고 있는 표준과는 달리 강제규정으로 운영되고 있다. 기술기준은 특성상 통신망 환경을 반영하여 규정되어야 하기 때문에 각국에서의 고유의 통신망 환경에 맞는 기술기준 체계 및 조직을 구축하고 기술기준 업무를 수행하고 있다. 본 고에서는 국내외 주요국의 기술기준 체계 현황 및 상호간의 차이점을 종합적으로 비교.분석하고 향후 발전전망을 나타내었다.

Plant industry is very important industry that dominate 70% of standard foreign countries construction acceptance an order woe 2004 years. Technique of plant industry is state that secure part equipment connection detailed design and construction class' competitive power. But, high added value creation among plant industry need technique elevation because available plan, basic design technology is insufficient. Therefore, high added value creation wishes to present problem of standard code and improvement direction for plant design to improve available plan, basic design technology competitive power.

Recently, the number of tourists using cruise ships in Korea is increasing. and an big cruise ship with an gross tonnage of 160,000 tons or more has entered the domestic ports. Therefore, the government has been making a lot of efforts to confirm the cruise infrastructure for revitalization of the domestic cruise industry. However, there are no standards for cruise ship specifications and water facilities in the domestic port and fishery design standards. Currently, construction of dedicated cruise facilities is under way in major domestic ports. However, due to lack of specifications and domestic standards for cruise ships, it is difficult to design and license special facilities. Therefore, in this study, PIANC rule and domestic harbor and designing standard of fishing port were compared and analyzed in order to present the standard specification of cruise ships. And analyzed the representative linearity of cruises currently being operated. As a result of the ship characteristics analysis, There was a difference in coastal passenger ship in specifications and ship maneuverability. Therefore, in order to design facilities dedicated to cruising, the specifications of the target ship must be included in the domestic design standard. In addition, in order to calculate the scope of the target ship, I applied the coverage rate of 75% to the average specification value of the cruise ship and presented the standards of the cruise ship and the standard of the water area facilities.

Aircraft engine and auxiliary power units are certified in processes of design, production according to airworthiness requirements. The aircraft engines shall demonstrate compliance with the design and production through the Type Certificate and the auxiliary power unit shall demonstrate compliance with the design and production through the Technical Standards Order Approval. MOLIT(Ministry of Land, Infrastructure and Transport) established the law and the airworthiness requirements for aircraft engines such as KAS Part 33 but didn't issue the Technical Standards Order for auxiliary power unit. In this paper, we proposed and explained the plan for improvement of our aircraft engines industry through building and expanding the certification infra-structure for aircraft engines and auxiliary power unit.

본 논문에서는 보의 주철근을 대상으로 건물정보모델링(BIM, Building Information Modeling)통합 설계 시스템 상에서 배근 설계 및 철근 형상화 알고리즘을 구축하여 자동배근 시스템(ARPM, Automatic Reinforcement Placing Module)을 개발하는데 목적이 있다. 구조분야에서의 BIM 프로세스는 정보호환체계를 구축하는 과정에 있으며, 철골 구조 프로세스의 경우 표준 호환 포맷을 이용하여 원활한 정보 호환 체계를 유지하고 있다. 하지만, 철근 콘크리트의 BIM 통합 설계 시스템은 철근 배근정보의 생성과 호환이 원활하지 않아 표준 정보 호환 체계가 구축되지 않은 실정이다. 기존 2차원 기반 프로세스에서는 철근 배근 설계에 있어 표준화된 기준에 따른 배근이 아닌 관행이나 일률적인 배근 지침에 따라 배근 상세를 정하고 있고, 2차원 배근 설계 결과만 제시하고 있어 상호 호환 가능한 철근 배근 정보데이터가 생성되지 않는다. 철근 콘크리트 구조에서의 철근 배근 정보를 생성하고 BIM 통합 구조 설계시스템에서의 정보 호환성을 확보하기 위해, 보의 주철근을 대상으로 구조 해석 데이터베이스와 통합 설계 플랫폼 간의 호환 시스템을 생성하고, 콘크리트학회 콘크리트 구조설계기준에 따른 배근 설계 및 철근 형상화 알고리즘을 구축하여 자동배근시스템(ARPM)을 개발하는데 목적이 있다.

In 2017, the Ministry of the Interior and Safety conducted research for the revision of seismic design standards and performed studies on standard design response spectra. As a result, the Common Application Guidelines for Seismic Design Standards were introduced, and these guidelines have been implemented in the national design standards of the Ministry of Land, Infrastructure, and Transport for practical use. However, it should be noted that the research for proposing standard design response spectra during the 2017 revision was conducted before the occurrence of the significant seismic events in South Korea, such as the 2016 Gyeongju Earthquake and the 2017 Pohang Earthquake. To account for these recent major earthquakes, this study adjusted the standard design spectra based on the records of the 2016 Gyeongju Earthquake and the 2017 Pohang Earthquake and conducted ground response analyses accordingly. The results revealed variations in peak ground acceleration (PGA) at the ground surface even within the same ground classification. It was confirmed that this variation can lead to overestimation or underestimation of seismic loads.
