바이오 플라스틱, 에코패키징, 인체 무해성 등과 관련하여 국내외적으로 다양한 규격 및 시험방법이 있다. 바이오 플라스틱(Bio plastics)은 최근 생분해 플라스틱(Biodegradable plastics), 산화생분해 플라스틱(Oxo biodegradable plastics), 바이오 베이스 플라스틱(Bio based plastics)의 3가지로 나뉘어지고 있는 추세이다. 생분해 플라스틱 규격기준은 국제규격인 ISO 14855를 기준으로 국가별로 자국내 규격기준이 제정되어 있고, 이에 따른 인증마크를 시행하고 있다. 최근에 아랍에미레이트(UAE)에서 국제 환경규제를 전면 시행하면서 부각되고 있는 산화생분해 플라스틱은 미국의 ASTM D 6954:2004, ISO 14855 등의 기준을 토대로 제정한 UAE S 5009:2009에 의해 시행되고 있다. 또한 산업화가 급속하게 추진되고 있는 바이오 베이스 플라스틱 관련한 규격 기준은 미국 ASTM D 6866을 기준으로 시행되고 있고, 일부 국가는 자국내 규격기준을 제정하여 인증라벨을 부여하고 있다. 현재 바이오 베이스 플라스틱 인증라벨은 2002년 미국을 시작으로 2006년 일본, 2009년 벨기에, 2010년 독일, 2011년 한국에서 시행되고 있다. 그 외에도 GR마크, 녹색 인증, 단체 규격 인증, 업계 자체 규격 기준 등이 다양하게 시행되고 있다.

IT 업계에도 저탄소 녹색 성장을 추구하는 Green IT 시대가 찾아왔다. 이에 따라 여러 IT 기업들에서 IT 자원을 소유하지 않고 빌려 쓰는 형태의 클라우드 컴퓨팅이 큰 이슈가 되고 있다. 클라우드 컴퓨팅은 기존의 조직이 유지 보수에 사용하던 인력과 비용을 감소시킬 수 있다는 점에서 경제적 이익을 창출하고 있다. 그러나 다수의 이해당사자(Mlti-tenant)가 존재하는 공공 클라우드 환경에서는 사용자의 인증이 보안 문제로 대두되고 있다. 본 논문에서는 공공 클라우드 환경에서 신뢰할 수 있는 클라우드 서비스를 제공하기 위한 사용자 인증 방법을 제시한다. 사용자는 계약관계로 맺어진 클라우드와 조직사이에서 클라우드 서비스를 제공받으며 조직으로부터 인증 받는다. 클라우드에서는 조직에서 제공하는 인증 정보와 클라우드의 서비스 제공 정책으로 이루어진 보안연계를 통해 사용자를 확인함으로써 사용자에게 적합한 서비스를 제공한다.

With the enactment of the "Framework Act on Carbon Neutrality and Green Growth to Cope with Climate Crisis," various sector-specific plans are being implemented to achieve carbon neutrality. School facilities are mandatory buildings for the "Zero Energy Building Certification" and are the buildings that account for the highest proportion among public institution buildings. Therefore, they play a major role in achieving carbon neutrality in the construction sector. This study analyzed the recent energy use trends and zero energy levels in varied ways to promote the spread of building energy management systems and to provide basic data for efficient operation management and investigated the effectiveness and user opinions of the Building Energy Management System (BEMS) applied to school facilities.

Recently, the most important paradigm is to prepare future and to protect the environment through the carbon savings occurs in everyday life and whole industry. For the success of this new paradigm, Korean government encourages the green certification and the development of green technologies and green growth as one of the important policies are adopted and implemented. Public agencies and companies establish the plans about the carbon savings and implement a lot of research has moved on using IT technology. There are some attempts in Korea to use as an electronic document instead of the use of paper document using these green IT and mobile devices. In this paper, the waiting sequence system using mobile phone is proposed as an example of practical engineering education for 'Low carbon, Green growth'.

Hydrogen is emerging as an essential material for carbon neutrality. In particular, Korea needs 22.9 million tons of imported clean hydrogen by 2050 to achieve carbon neutrality. However, a large amount of carbon is emitted during the import process, and market regulations are being discussed. This research estimates the carbon emissions of importing green hydrogen from Vietnam, Australia, and the United Arab Emirates to Korea, and calculates imported green hydrogen prices under carbon emission market regulations.

The paper affirms the weight proportion concept as an element, which could be empirically analyzed quantitatively through the developmental expansion of qualitative empirical analysis on taxonomy that is required for the construction Low-Carbon Green Cities and their eco-friendly elements, such as a pleasant residential environment The weight proportion concept is proposed as a new measure to identify eco-friendly elements and as an objective assessment indicators. To perform an empirical analysis, surveys were first given to the residents of Metropolitan Newtown (50 persons) and outside experts (50 persons) for the total of 100 persons. Second, the paper surveyed 74 sites of Eco-Environmental Certified Apartment Housing Complexes. Upon analysis of eco-friendly elements by their type and total weight, the largest weight proportion was expressed in the interior and eco-environmental elements, carbon-decrease types, and carbon-absorption types. The results of this paper confirm recent positive sentiments and preference toward a variety of future-oriented and sustainable eco-friendly elements like the eco-housing and new renewable energy, In addition, the paper affirmed the new housing trend towards constructing eco-friendly elements, such as carbon-decrease and carbon-absorption, that induce long-term investments, despite their need for higher investments.

Recently, there are effects such as commercial investment and introducing new technology by introducing a BTL project. As a result, School's conditions are getting better and Numbers of certified schools are increasing, because the Green Building Certification Criteria was created in 2002 and expanded to schools in March, 2005. But the certificated schools just get the minimum score for certificate level 'good' about 65 points and there is no certificated school level 'very good'. The users of school stay in long time in the facility cause of the unique function of school. It means Indoor Environment Quality Criterion of the school is very important than any other criteria. Therefore, this study aims to analyze the indoor environment factor for the plan of the certificated school by green building rating systems. And this study also wants make the basement of a substantial technical application and development of the criteria in the plan for sustainable green school.

The purpose of this study is to suggest the way how to improve the school green building certification system based on life cycle assessment methodology and to assess $LCCO_2$ in outline. Green Building Certification System for School is comprised of 7 categories and 39 items. 7 categories include Land use and Transport, Energy and Atmosphere, Materials and Resources, Water, Management, Ecology, Indoor environmental quality. School is a public facility for students. So Green Building Certification System for School must have educational point of view adding to energy saving, reduction of greenhouse gas emission, etc. Also it needs to be classified into three categories ; kindergarten, elementar/middl/high school and university. Improvement plans for items are as follows ; energy consumption and $LCCO_2$ assessment considering life cycle, deletion or integration of duplicate items by comparing other systems, application of passive solar systems, consideration of the law and standards change, and selection of items considering specific building use.

Currently, as the public interest for environmental issues has grown rapidly, the needs for G-SEED have also increased. However, as investment according to eco-friendly elements is inevitable to receive G-SEED certification, it is necessary to find out whether or not the sales price of apartments have increased compared to investment costs. Therefore, the objective of this study is to analyze the sales price of apartments according to G-SEED by using T-test. To achieve the objective, First, variables affecting on the sales price of apartments are selected. Second, the data are collected by using GIS(Geographic Information System). Third, after testing the normality, a comparison analysis is conducted on the sales price between G-SEED certified and non-certified apartments by using T-test. As a result, it is concluded that G-SEED certified apartments are more expensive than non-certified apartments. In the future, these findings can be utilized to develop of apartments price calculation model based on the G-SEED.
