In 1990s, as the extreme weather events according to the global warming climate change are occurred frequently all around the world and the scale of the damage increases, the developed countries are promoting various policies for reducing greenhouse gas emissions setting the goal of greenhouse gas reduction with the level of State and local government. Especially for the greenhouse gas reduction of buildings and the inducement of eco-friendly design, the green certification system is strengthened with the assessment of energy and greenhouse management, and recently, according to the policy change of climate and energy, the certification system expanded from the buildings to the level of city and district is piloted. So this research is to understand the main contents and the assessment system of domestic green building certification system implemented in March 2013 in response to the policy change of climate and energy and to suggest the basic data for the improvement of present domestic greenhouse certification standard through the analysis of actual certification and the main case analysis of international green certification system. Recently in developed countries, in 1990s, for the reduction of building's greenhouse gas emission and the inducement of eco-friendly design, from the building of LEED, BREEAM, DGNB to the level of city and district such as LEED Neighborhood Development, BREEAM Communities, DGNB Stadtquartiere, the system is expanded and piloted. On the contrary, as for the domestic standard of green building certification system, the distribution ratio according to the assessment items in each category consists of the assessment system based on the buildings, and just the simple adjustment of some items and the improvement of weighted value are performed. Actually, as a result of selecting the 30 districts of apartment housing with the most certification performance by use among the 49 buildings certified by Institute of Land & Housing from December 2014 to July 2016 and analyzing the assessment score, the certification level is determined by the sectors of high distribution like indoor environment and energy not by the ineffective sector of external environment with low distribution so this system has a limitation to perform the practical means for the policy change of climate and energy. Thus for the national green building certification standards, the assessment system in the sector of external environment is to complemented and furthermore, reflecting domestic reality, through the introduction of certification system and the assessment system with the level of city and district, this system should be improved to meet the international certification standard.

In spite of some similarities between KS(Korean Industrial Standards) certification audit criteria and ISO 9001 certification requirements, most of companies manage the two certification systems independently. In this study, we analyze two certification systems, find common points and propose a model or guideline of the integrated system management for small companies. This research compares KS criteria with ISO requirements in detail. A survey is carried out to check and review the situation of the manufacturers which obtain both KS and ISO 9001 certification. Survey results show that there is a small difference in certification management according to company's size, but some benefit points of the integration management regardless of company's size.

This study investigates consumers' purchasing behavior and perception of the low-carbon certificated agricultural product. To this end, we surveyed 1,000 consumers and the main findings are as follows. First, Even after six years of national certification, it is important to promote the low-carbon certification system due to insufficient awareness and purchase experience. Second, the certificated area is small at around 5% of the area of environment-friendly agricultural products and GAP certification, and certification is concentrated on fruit trees. Third, an appropriate level of high-priced strategy can be useful considering the cost of low-carbon certification, image management of low-carbon certificated agricultural products, and quality is the most important factor for consumers to consider when purchasing fresh agricultural products. Fourth, consumers recognized that the contribution of low carbon certification in reducing greenhouse gas emissions and preserving the environment was higher than that of environment-friendly agricultural products or GAP certification. Considering that, promotional activities linked to environment-friendly agricultural products and GAP certification may be effective when promoting low-carbon certification. Finally, the Ministry of Agriculture, Food and Rural Affairs is implementing a carbon point system linked to Green Card to revitalize low carbon certification, but 25.7% of consumers are aware of it, and 8.4% have little experience in issuing it.

현재 국내의 무인항공기 기술은 첨단성과 산업 경쟁력 측면에서 모두 항공 선진국에 비해 뒤쳐져 있지만 무인항공기를 기존의 유인 항공 체계에 편입하고 산업에 응용하고자 하는 세계적 노력을 방관만 할 수 없는 실정이다. 무인항공기는 기존의 항공 체계에 비교적 새로운 시스템이지만, ICAO는 체약국들과 항공업계가 무인항공시스템을 좀 더 이해하고 활용을 촉진할 수 있도록 많은 노력을 기울이고 있다. 특히 무인항공기시스템을 원격조종항공기시스템(RPAS)과 기타의 무인항공기시스템으로 분류하고, 가까운 장래에 RPAS를 유인항공기 영역에 통합해서 운용하기 위한 표준화 작업을 선도하고 있다. 이러한 취지에서 ICAO는 RPAS의 글로벌 운용을 위한 표준화를 추진하게 되었고, 본 연구에서는 ICAO 표준화 활동을 포함한 국내 RPAS 인증체계 구축 전략 연구를 수행하게 되었다. 따라서 본 논문에서는 RPAS 안전에 대한 국내외 규제 프레임워크를 분석하고 국내 RPAS 인증 체계 구축을 위한 전략을 제시하였다.

The ZEB certification system has come into effect since 2018 according to the ZEB road map. From 2020, the public buildings with the total floor area smaller than $3000m^2$ are the target of the certification, and it will be extended to the buildings with up to $5000m^2$ floor area in 2025. However, current mandatory regulations for public office buildings seem already to meet the ZEB certification system planned for 2025. In this work, two buildings belong to $3,000{\sim}5,000m^2$ in total floor area were selected to analyze the possibility of meeting the ZEB certification only by following current obligation regulations. Results showed that the test buildings satisfied the minimum building energy efficiency and energy self-sufficiency rates for the ZEB certification when the mandatory insulation and installation ratio of renewable energy are applied. This can be useful for revising the road map or extending the target buildings of the ZEB certification.

A survey was conducted on the awareness and demand for the Multi-crew Pilot License (MPL) to prepare the legal institutional basis for the MPL certification system. A total of 288 airmen were asked questions about the awareness and demand of the MPL certification system, and factors affecting the establishment and participation of MPL training programs. The survey results show the understanding of the MPL certification system is significantly lower than that of the current pilot certification system. The demand for the MPL training program was found to be significant, trainees and low-skilled airmen was greater demand. The factor that has the greatest influence on the establishment and participation of the MPL training program was identified as employment connection (airline recruiting). It is expected that the result of this study will be used as basic data necessary for establishing MPL certification system policy.
