Ulsan made its contributions to modern Korea as an industrial city. In the 1960s, Ulsan was appointed as a special industrial zone. After that, industrial complexes were built without environmental considerations so Ulsan was once called "the polluted city". However, in the early 2000s, the main concern of Ulsan's policies was gradually shifted from the economic growth to the environmental issues. In order to enhance the environmental quality and to make the Ulsan more environmentally friendly eco-city where human and nature coexist, Ulsan city declared "The Eco-polis Ulsan" in 2004 based on "The Master Plan for Eco-polis Ulsan" which included the eco-industrial park as an action plan. This study aims at defining the concepts of eco-city and policies to build Ulsan-style eco-city as environmentally friendly city and proposing Ulsan as a role model to cities and towns of developing countries. In addition, Ulsan's EIP project which will be implemented for 15 years from 2005, is elaborated including regulatory issues and technologies to be applied.

The "Eco-friendly", "Green" concepts was began around 1992 after the Rio Environmental Summit, and the need for sustainable development globally widespread. The green building certification system was began around 2000 and the concept of green building was started in the late 1990s. The green building, which welcomes a period of radical change, is for the survival of the Earth "climate change" and reducing energy consumption in building sector. In this architecture of eco-friendly concept, the green building is rapidly expanding and existing as a ecological environment preservation. Moreover, the realization of zero energy house is to mandate for new buildings in 2025. The aim of further eco-friendly is through the prior ecosystems to restore and product energy for the 9 Green Building model houses in this paper. Building in the concept of ecology is to show about change into 7R's from the 3R's. The "Reduce", "Reuse", "Recycle" consisting of "3R's" is correlated with the traditional to the present Green Building Design. U.S. NCARB (National Council of Architectural Registration Boards) change into the concept of 7R's as "Receive", "Restore", "Respect" and "Remember", added to "3R's". In this paper, the 9 Green Building model houses do not meet the criteria of 7R's. But, the Green Tomorrow of Samsung C & T Corporation meet the 6 criteria for 7R's. This company is most comfortable at low carbon Green Building model houses.

The global waste crisis has been escalating and its consequent impact on soil, water, air pollution, and eventually climate change acceleration has shed light on the importance of reducing waste. Amidst COVID-19 and the following surge in single-use plastics for food delivery, waste generation is on the incline. Companies and governments have embarked on developing various eco-friendly packaging technologies, but their effectiveness on the consumers is vague as definitions of eco-friendly packaging are vague, and research on its link to purchase intention remains scarce. Thus, the adoption of eco-friendly packaging has been slow. To address this issue, this study analyzes the awareness and purchase intention of four visual attributes of eco-friendly packaging-material, verbal statement, eco-label, and color-along with the environmental consciousness among undergraduate university students in Korea through online surveys and the ordered logit regression model. The study distinguished the attributes into evidence-based and conjectural categories. The findings revealed that eco-friendly visual attributes had a positive effect on purchase intention amongst undergraduate students in Korea; however the level of environmental consciousness had marginal effect on the purchase intention of eco-friendly visual attributes. The level of effectiveness also varied with each visual element. Analyses revealed that visual attributes to eco-friendly material had marginal effect on purchase intention; color was deemed not an "Eco-friendly attribute" by most students, and although eco-friendly labels were deemed as an eco-friendly attribute, trust in the labels varied according to environmental consciousness. These findings have implications for businesses and policymakers aiming to promote eco-friendly consumption within packaged food products.

Since Seoul city supplied 'Sangsang Children's Playground', domestic playgrounds are changing from formal facilities to creative play and learning space recently. From eco-friendly safe playground model development project, eco-friendly playground planning and its actual cases have been occasionally introduced. However, we could not know how well most playgrounds reflect eco-friendly features and whether they are eco-friendly or not because the definition about the concept of eco-friendly playground is inadequate and there are not the specific planning guidelines and evaluation standards for making the eco-friendly playground. Therefore, the development of guidelines for the construction of eco-friendly playground is required and evaluation guidelines for them should be made for the active dissemination of the actual eco-friendly playground and the proper construction of the eco-friendly playground. In this study, we defined the concept of eco-friendly outdoor playground and presented the types and characteristics of the playground based on the concept and suggested basic plan guidelines based on the existing requirements for becoming eco-friendly playground. For this purpose, we checked the plan's common points in the existing playground configuration requirements, installation standards, regulations, and safety standards, and offered the planning elements and guidelines through the analysis of outdoor space evaluation standard in eco-friendly safe playground guidelines and eco-friendly building certification system.

A simple bimodal model has been developed to analyze charged particle coagulation by modifying previously suggested bimdal model for evolution of particle generation and growth. In the present model, two monodisperse modes are used and 40 charge nodes are assigned to each mode to account both change of the particle size and charge distribution. In addition, we also implemented the effect of electrostatic dispersion loss in the present model. Based on the developed model, we analyzed coagulation of asymmetric bipolar charged particles by computing evolutions of particle number concentration, geometric mean diameter of particles, charge asymmetric ratio and geometric standard deviation of particle size distribution for various initial charge asymmetric ratios. The number concentration of asymmetric bipolar charged particles decreases faster than that of neutral particles but that does not give faster growth of particles since the electrostatic dispersion loss overwhelms particle growth by coagulation.
