The purpose of this study is to compare and analyze the educational philosophy, goal, method, content, and environment of ecologically-oriented alternative elementary schools and suggest several practical methods for alternative education. Both ecologism and alternative education pursue sustainable values. The educational content of ecologically-oriented alternative elementary schools, analyzed from the view of sustainable development, focuses most on the natural resources, biodiversity, and sustainable food production, and also include human rights, peace and security, unification, cultural diversity, and health food in terms of the social sustainability and sustainable production and consumption concerning economic sustainability. This study should help environmental education become establish its possibility and position as alternative education and be recognized of its educational value. Furthermore, based on the cases of ecologically-oriented alternative elementary schools that are becoming 'garden of environmental education' as sustainable development education, it should lead to 'education communicating with environmental education at schools'.

In its Declaration of Principles, the United Nations Conference on Environment and Development recommends that, "to achieve sustainable development and a higher quality of life for all people, states should reduce and eliminate unsustainable patterns of production and consumption...." This notion of sustainability lies at the core of many "commons" problems, where the central issue is to enable "individuals to sustain long-term, productive use of natural resource systems". In other worlds, a common definition of "sustainability" captures the idea of aligning human consumption with the capacity of ecological systems to supply, over a long period of time, such natural resources as air, soil, or water on which production depends. The concept of sustainability raises all sorts of political, social, and economic questions about the distribution of environmental protection. For sustainable community development to be addressed, these questions must be raised. In order to convince different citizenry of the necessity of sustainability, these questions must also be answered. This is where questions of equity, justice, and fairness arise. Sustainability and equity require that we deal with nature as an undivided whole, with no part being unsustainable. Sustainability and social policy also requires that we deal with the human population as an undivided whole. We simply cannot move people around the planet to either perpetuate past practices of earth exploitation or to implement sustainable planning. Everyone must work with the people inhabiting sensitive ecological areas, especially areas of regeneration. In the sustainable global community, we are as strong as our weakest link, or our most toxic community. This is the undeniable driving force for the infusion of equity into the sustainable development debate.

This study was carried out to improve the electric power consumption of HVAC in the blow mold machine(BMM) and work environment. The experiment was conducted with the simulated HVAC system of 1/15 of the actual BMM. The temperature of main facility and two preheaters was fixed at 200 and $60^{\circ}C$ respectively in all test conditions. The measured points of temperature were chosen as critical locations considering the work environment. The tendency of temperature distributions decreases as the duct was closed to the main facility. The reduction rate of power consumption of HVAC increases up to 32.3% when both duct and cooling systems are operated. Also the efficiency of HVAC is improved about 9% through the modified design of duct system. It notes that the electric power consumption of HVAC can be reduced by the optimum design and operating condition of duct and cooling system.

Anomaly detection on building energy consumption has been regarded as an effective tool to reduce energy saving on building operation and maintenance. However, it requires energy model and FDD expert for quantitative model approach or large amount of training data for qualitative/history data approach. Both method needs additional time and labors. This study propose a machine learning and data science approach to define faulty conditions on hourly building energy consumption with reducing data amount and input requirement. It suggests an application of Support Vector Data Description (SVDD) method on training normal condition of hourly building energy consumption incorporated with hourly outdoor air temperature and time integer in a week, 168 data points and identifying hourly abnormal condition in the next day. The result shows the developed model has a better performance when the ${\nu}$ (probability of error in the training set) is 0.05 and ${\gamma}$ (radius of hyper plane) 0.2. The model accuracy to identify anomaly operation ranges from 70% (10% increase anomaly) to 95% (20% decrease anomaly) for daily total (24 hours) and from 80% (10% decrease anomaly) to 10%(15% increase anomaly) for occupied hours, respectively.

The purpose of this study is to analyze policies on environmental-friendly agriculture(EFA) and find out some implications. As we know well, EFA contributes environmental substantiality by using organic production methods and provides consumers with a secure, safe nutritious food supply. As consumption of environmental-friendly agricultural products increasing, policies on EFA began in the 1990s and it has been generally expanded in Korea. The strategies for sustainable EFA aim to promote harmony among human beings and between humanity and nature require. In addition, support to develop marketing activities, regionalization, and political support must be further developed.

The fashion industry is facing numerous sustainability-related challenges due to growing consciousness about the egregious extent of global environmental problems. This study examines research trends on sustainable fashion based on five macro trends related to sustainable innovation in the fashion industry. Using the content analysis and network analysis methods, 115 research papers published in domestic and international journals from 2017 to 2021 were collected and analyzed. The study conclusions are as follows. First, majority of domestic papers(55.41%) focused on circular economy, whereas other topics such as consumer awareness(1.35%) and corporate social responsibility(2.70%), are yet to be thoroughly examined; majority of international papers(53.65%) focused on sharing economy and collaborative consumption, whereas other topics such as technological innovation(2.44%), are yet to be thoroughly examined. Second, domestic papers have found that many brands(68.57%) are applying the concept of circular economy, whereas international papers have found that many brands(51.56%) are applying the concept of sharing economy and collaborative consumption. The study results provide useful data for corporate management in the fashion industry.

This study developed teaching-learning materials for 10 class periods that applies design thinking process for the units of 'sustainable consumption' of home economic subject, and examined the learning experience of students in the class. After the classes, reflection journals and in-depth interviews from 276 male and female students in ten classes were analyzed. The main results are as follows: The five steps of the design thinking process of the Stanford University d-School were applied to develop teaching-learning materials for the 'Sustainable Consumption Practice Book Creation Project'. Students' positive learning experience was evidenced through sustainable consumption classes that applied design thinking. The students were able to reflect through the experience of sympathizing with the real problem, and experienced an improvement in problem-solving ability through the process of idea construction and prototyping. Students expressed difficulties in reaching consensus among the members, and in devising ideas and implementing prototypes. Based on the learning experience of students this study, it is suggested that home economic teachers further develop and implement classes of various topics to which design thinking process is applied. A future study may need to verify the effectiveness of home economic classes to which design thinking is applied.

The global warming caused by consumption of fossil fuel and energy has been interested. Therefore, several policies and regulations have been discussed to reduce greenhouse gas emission and effective energy consumption. The construction industry that takes 45% of energy consumption makes efforts to develop green construction methods and materials and reuseable energy. However, there is no common definition to calculate greenhouse gas and database in the construction industry. Especially, transportation infrastructure like road, railway, harbor, and airport consumes 21% energy of construction facilities. Therefore, this paper develops the causal relationship to define performance of sustainable road construction and maintenance. The performance indices are grouped into economic, social, and envirionmental impacts. Then, the causal map is developed based on survey results of construction experts. This will provide the baseline to evaluate the performance of sustainable construction and to establish the objective goals.
