Eco-driving technique for electric vehicles (EVs) is investigated in this paper. Many findings on EVs have been reported; however, they did not deal with eco-driving from the viewpoint of theoretical study. The authors have developed an energy-saving driving technique - the so-called "eco-driving" technique based on dynamic programming (DP). Optimal speed profile of an EV, which minimizes the amount of total energy consumption, was determined under fixed origin and destination, running time, and track conditions. DP algorithm can deal with such complicated conditions and can also derive the optimal solution. Using the proposed method, simulations were run for some cases. In particular, the author ran simulations for the case of a gradient road with a traffic signal. The optimization model was solved with MATLAB.

Since Seoul city supplied 'Sangsang Children's Park', domestic children's parks are changing from formal facilities to creative play space recently. From eco-friendly safe playground model development project, the awareness of eco-friendly playground, namely children's park is increasing and its necessity is magnified. However, we could not know how well most children's parks aimed at the eco-friendly playground reflect eco-friendly features and whether they are eco-friendly or not because there are not the specific planning guidelines and evaluation standards for making the eco-friendly playground or children's park. Therefore, in this study we established the environment-friendliness evaluation standards of children's parks and estimated the environment-friendly features of the 9 parks built on the subject of green among Sangsang Children's Parks. In the observational survey of the 9 parks, we evaluated the environment-friendliness of these parks in the 8 fields(location and placement, ecological environment, play space, play equipment and facilities, additional facilities, materials and resources, energy saving, environmental load reduction) according to the levels(suitable, partial reflection, unsuitable, non-reflection) of reflection of eco-friendly planning factors. The assessment results showed that 4 items (location and placement, additional facilities, play space, play equipment and facilities) were suitable and others (energy saving, environmental load reduction, ecological environment, materials and resources) were partial reflection or unsuitable. Therefore, on the basis of these results, this study proposed the planning indicators to be considered first and the planning factors that should be complemented and improved in the construction of eco-friendly children's park in future.

The purpose of this study is to consider for the introduction of the school eco-audit system as an educational method for sustainable development. First of all, the concept and objective of the education for sustainable development(ESD) are reviewed in order to advance a theory on school eco-audit system. ESD which under the premise of global inter and intra generation justice, resolves to address a mixture of ecological, economical and social aspects, as well as safeguarding limited resources and protecting the environment from pollution and energy. In order to effectively structure uncoordinated environmental activities carried out by schools, the introduction of school eco-audit system in Korea is suggested, which as the model for long-term development, has since been integrated into the school's programme. Activities related to waste, heating, electricity and water are run by a 'Management Team'. By combining all 3 fields of action - i.e. establishing basic organizational conditions, education, and individual ecological measures - the eco-audit proves to be the key to success. In particular, administration agency and method, institutional improvement are presented.

Purpose: As global interest in environmental issues increases, the demand for green products/services is increasing. Companies are establishing eco-friendly policies to meet the changing expectations of customers. Therefore, this study aims to analyze the effect of eco-friendly behavior and third-party certification on trust, satisfaction, and loyalty as well as the mediating role of satisfaction based on SOR and signaling theory. Research design, data and methodology: This study collected data from 501 respondents who visited restaurant and analyzed using measurement model with SPSS 28.0 and SmartPLS 4. Results: First, restaurants' eco-friendly behavior and third-party certification (TPC) positively influenced trust while these did not influence satisfaction. Second, trust positively influenced satisfaction. Third, trust and satisfaction positively influenced loyalty. Fourth, TPC had stronger impact on trust and satisfaction compared to eco-friendly behavior in female group while TPC had stronger impact on trust in male group. Conclusions: This study emphasized the importance of TPC over eco-friendly behavior. Restaurants should maintain pro-environmental behaviors such as reducing single-use items while obtaining TPC such as ISO and LEED certifications to increase customer trust. It also found the importance of trust and satisfaction in securing loyal customers. Restaurants should make efforts to build bonds with customers through authentic marketing such as events that encourage customer participation.

In this research, we examined the shifts in determinants influencing the frequency of eco-friendly food purchases pre- and post-COVID-19. Our analysis utilized filtered 2019-2021 Consumption Behavior Survey data from the Korea Rural Economic Institute Food, excluding any irrational responses. Given the nature of the dependent variable, a multinomial logistic regression model was employed with demographic factors, variables pertaining to food consumption behavior, and variables concerning food consumption awareness as predictors. Following the onset of the COVID-19 pandemic, an individual's level of education was observed to positively influence the frequency of eco-friendly food purchases. In contrast, income level and fluctuations in food consumption expenditure did not appear to have a discernible impact on the purchasing frequency of such eco-friendly products. Irrespective of the advent of COVID-19, variables such as the frequency of online food purchases, the utilization of early morning delivery services, dining out frequency, and the intake of health-functional foods consistently demonstrated a positive correlation with the propensity to purchase eco-friendly foods. Overall, consumers prioritizing safety, quality, and nutrition over price, taste, and convenience in their procurement decisions for rice, vegetables, meat, and processed foods exhibit an increased inclination toward the acquisition of eco-friendly food products.
