This study aims to identify differences and lessons in eco-school planning techniques and sustainable design methods by analyzing comparatively green building certification system and the cases of sustainable schools in US, Korea and Japan. As a result of the comparative analysis, green building certification system for school facilities, both domestic and international, is categorized into external environment, energy, materials and resources, and indoor environment. From the case study, it is common that roof garden and biotopes are installed for external environment, while energy saving, passive energy utilization methods for natural lighting and ventilation such as arrangement planning, courtyard, top-light, shading devices, solar panel and insulation by roof garden are most frequently used. Also, storm water uses, water saving equipment and sustainable materials are often introduced for resource savings. Concerns for indoor environment is frequently addressed by introducing natural light and ventilation in the buildings, which makes ultimately a comfortable space.

국내에 청정생산기술에 대한 개념이 도입된지 16년이 되었지만 아직도 청정생산기술에 대한 정의와 의미가 중소기업들에 확산이 되지 않은 상황이다. 본 연구에서는 청정생산기술에 대한 개념과 구분을 살펴보고, 환경기술과 녹색기술과의 관계 그리고 국내외에서 구분하고 있는 기술 종류 등을 비교분석하였다. 그리고 국내 중소기업들에 청정생산기술이 확산되기 위한 방안으로 현재 정부에서 지원하고 있는 지역에코혁신사업을 확대하는 정책 제안을 하였다.

Livestock farmers are using animal carcasses to dispose of the carcasses of livestock that have died of natural causes or disease. Most of the existing livestock carcass processors are mechanical in their structure without considering the environment. It has a function of sterilizing dead bodies at high pressure after processing them and causes environmental problems such as carbon monoxide emissions. If livestock carcasses occur, livestock farmers have to purchase their own livestock carcasses or entrust them to the outside world, which is costly. For this reason, the possibility of environmental pollution, infectious diseases, and spread has been increased recently by frequent dumping of dead bodies. The carcass of livestock mixed with manure not only serves as a medium for infectious diseases but also needsto be buried on a large scale as foot-and-mouth disease and avian influenza spread. As a result, the possibility of environmental pollution, such as contamination of groundwater, is increasing, so research is needed to protect and improve the environment. We aim to improve the process of processing livestock carcasses and purify the agricultural environment through development results on the form, structure and function of eco-friendly livestock carcasses. Its shape is applied with naturalshapessuch asstones and seeds. The material used in the dead body processis a brown beggar biocouple and is applied with an eco-friendly industrial animal recycling process. As a result of the study, it is expected to improve odors and the environment, and to be used as data to improve and help the livestock industry in the future.

With the commercialization and full-timeization of the livestock industry, civil complaints continue to increase, and the livestock industry is facing a crisis due to social problems such as odor caused by livestock manure, soil pollution, water pollution, and environmental pollution. In order to increase productivity in livestock farms, the amount of livestock manure generated is increasing due to excessive use of protein feed and high-density breeding environment, and complaints such as odor and water pollution due to management problems are increasing rapidly. Livestock odor has emerged as a serious social problem, and due to growing complaints, conflicts between the Ministry of Agriculture and Forestry and the Ministry of Environment are even causing the livestock industry to lower its status. There is an urgent need for solutions to identify problems in the livestock industry and improve policies. This study aims to develop a " Abelmoschus Manihot Jinhuakui " brand that can improve the intestinal environment of livestock, reduce odors caused by livestock excrement, and improve the productivity of livestock farms in order to improve the increasingly serious odor problem in livestock sites. For Jeju livestock farms, which place more importance on the environment by securing tourists, eco-friendly feed additives were applied to the experiment, the results were derived, and the focus was on solving fundamental problems of odor generation through the development and packaging of feed additive brands. We aim to fundamentally solve the odor problem of domestic livestock farms, secure eco-friendly livestock farms, and contribute to reducing livestock odors and increasing productivity through research results that reduce ammonia levels in each livestock farm.

Purpose: The purpose of this study is to present an efficient emission reduction ratio of plastic to reduce carbon dioxide, the main cause of greenhouse gases. Research design, data and methodology: This study calculated the absolute value of carbon dioxide by setting an equation through the emission coefficient using the US EPA's WARM model. Results: In the recycling ratio of 70%, it was found that the energy recovery ratio was 15.6%, which was the energy recovery ratio without generating carbon dioxide. When carbon dioxide is generated by changing plastic waste emissions, optimal efficiency is achieved by reducing emissions by 10% to 30% of energy recovery ratio, 20% to 50% of energy recovery ratio, and 30% to 80% or more of energy recovery ratio. Conclusions: The recycling rate should be set at a minimum of 70%, so that a carbon dioxide-free energy recovery rate could be obtained during the recycling process, supporting an eco-friendly basis for environmental policies aimed at this rate. In addition, it was possible to suggest that it is essential to reduce emissions by at least 30% for eco-friendly recycling measures that can achieve both economic and environmental feasibility in the energy recovery process through incineration during recycling in Korea.

We developed the Eco medium for Escherichia coli and total coliforms, which was modified by Violet Red Bile (VRB) medium, and derived the standard curve of exponential phase at $OD_{410}$ by using type strains such as E. coli ATCC11303, Enterobacter cloacae KCTC2361, Klebsiella pneumoniae KCTC2241, and Citrobacter freundii KCTC2359. Also, we used total 93 samples of spring and stream water to compare the detection ability of total coliforms between the method using Eco medium and such as most probable number (MPN), and plate count methods. As a result, the qualitative analysis of E. coli and total coliforms using Eco medium contained ortho-nitrophenyl-$\beta$-galactoside (ONPG) and 4-methylumbelliferyl-$\beta$-D-glucuronide (MUG) was same as those of Korean standard methods (Colilert kit). And the colony forming unit (CFU) detected in Eco medium was similar to those of result from MPN and plate count methods. Moreover, the agreement, sensitivity, and specificity of the developed kit was more than 97.5% in comparison with Colilert kit for 350 samples. Thus, the Eco medium can be used both qualitative and quantitative analysis of E. coli and total coliforms.

본 연구는 대학생들의 라이프스타일 유형을 분류하여 그 유형별로 환경의식에는 어떠한 차이가 있으며, 환경의식은 친환경제품의 구매의도에 어떠한 영향을 미치는가를 분석하는 데 연구의 목적이 있다. 그 결과를 요약하면 다음과 같다. 첫째, 라이프스타일 유형 중 건강지향형은 환경실천과 환경보호의 모두에서 유의한 수준으로 나타나 가설이 채택되었다. 그러나 자기추구형과 적극활동형의 유형은 모두 유의하지 않은 값으로 기각되었다. 둘째, 환경보호가 높은 집단이 친환경제품 구매의도에 있어서 유의한 수준으로 가설이 채택되었다. 따라서 건강지향형의 라이프스타일을 지닌 대학생들이 환경에 대한 의식이 높았으며, 환경보호의식이 높은 집단에서 친환경제품에 대한 구매의도가 높다는 사실을 알 수 있다.
