The fashion system has been criticized for relying on a linear economy to reduce short-term costs and increase profits. Meanwhile, the circular economy strives to expand the value chain through a closed loop for companies, society, and the environment by separating consumption from resources. This study aims to elucidate the strategic characteristics of the technological measures that fashion companies and brands are trying to innovate into a sustainable fashion system on the basis of the circular economy concept. Thus, we conducted case studies by dividing the value chain of the fashion system into design, production, and consumption to identify the technological development of the circular fashion system from a technologization perspective that incorporates technological values. First, design appeared to strengthen emotional durability, design and process with circulation in mind, and fashion product digitalization. Second, production manifested itself as material development for the new fiber economy, improvement of non-environmental processes, and customization of demand-driven, responsive production. Third, consumption was the spread of the environmental consumption culture through the sharing economy platform, the realization of a virtual wearing experience to prevent rapid disposal, and the provision of information on sustainable consumption.

Sustainability is commonly recognized as one of the new paradigms or norms that will reign the new era after the modern age of revolutionary economic development. This global trend calls for the adoption of the sustainability concept to soil and groundwater management. In fact, there are several such ongoing movements in practicing soil and groundwater management. Through literature review, this paper discusses the concept, practices, and future research needs of sustainable soil and groundwater management. We first discuss the definition of sustainable soil and groundwater management and possible methodologies to gauge or improve the sustainability of soil and groundwater management. Then, we introduce the research topics, exemplary practices, and propose solutions to elaborate sustainability in three representative subfields including soil and groundwater remediation, groundwater management, and soil management. We conclude with suggestions on the future research directions for successful adoption of sustainability concept to soil and groundwater management in the Republic of Korea.

Sustainable supply of minerals and energy is global problem. Metals and energy consumption in the world has increased with economic growth. Currently more than 40 metals are systematically extracted and used in many different fields in civilized society. Recycling and reuse have become very important because recycling contributes to supplying the materials and protecting the environment of society. It is not realistic that all waste materials are capable of being recycled, because recycling metals have fundamentally been competing with primary production. In this point of view, prior to discuss on current recycling technology of waste resources in Korea, world wide trend and Korean recent activity in the supply-demand far minerals and energy resources are reviewed.

Plans to utilize the resources of the coast guard are underway for the revitalization of the area and the development of tourism resources in recent years. As most of the plans have been focused on some specific factors such as geographical or regional conditions, and therefore systematic approaches are needed in corporation with other related projects. This study suggested the measures on activating the coastal tourism resources for Woodoo~Woocheon village in Goheung-gun by using the coastal landscape elements. The current status of natural environment and tourism resources for coastal regions were investigated in Woodoo~Woocheon village and plans for enhancing connectivity with local residents were suggested. Based on the scenic values of coastal region, landscape were assessed from the perspective of the sustainable coastal tourism resources in the future. Several solutions were suggested to enhance tour values; coastal deck road to enhance connectivity between resources and accessibility of foreign tourists, social communication among local residents and authorities, continuous development of cultural and historic resources in local area. In addition, information signs and new stair ways would be needed to improve the accessibility of tourists. In the future, if the plan for this study was to generate profitability with persistence, it suggested that there was a way to move forward in conjunction with the profit rate local projects distributed around it.

Cultured meat is under investigation as an environmentally sustainable substitute for conventional animal-derived meat. Employing a scaffolding technique is one approach to developing cultured meat products. The objective of this research was to compare soy and pea protein in the production of hydrogel scaffolds intended for cultured meat. We examined the gelation process, physical characteristics, and the ability of scaffolds to facilitate cell adhesion using mesenchymal stem cells derived from porcine adipose tissue (ADSCs). The combination of soy and pea proteins with agarose and agar powders was found to generate solid hydrogels with a porous structure. Soy protein-based scaffolds exhibited a higher water absorption rate, whereas scaffolds containing agarose had a higher compressive strength. Based on Fourier transform infrared spectroscopy analysis, the number of hydrophobic interactions increased between proteins and polysaccharides in the scaffolds containing pea proteins. All scaffolds were nontoxic toward ADSCs, and soy protein-based scaffolds displayed higher cell adhesion and proliferation properties. Overall, the soy protein-agarose scaffold was found to be optimal for cultured meat production.

This study found that introduction of environmental systems and increased environmental investment have a major impact on K company's sustainable development. The analysis indicated that the environmental investment variable has a close relationship with production quantity, sales, and the amount of sludge treatment variables in K company. However, all other variables including the cost of disinfection chemicals, and the expenditure of sludge treatment have no relationship with the environmental investment variable. Additionally, short-term results show that the company's environmental expenditure variable is conversely related with the environmental performance variable.

A country's macro developing strategies will greatly impose upon its water resources allocation. Based upon the relationship between national macro developing strategies and water diversion projects layout, the paper discusses the vital influence of water diversion projects caused by China's food security and sustainable development strategy implemented in recent years, and points out that it is an inevitable choice of constructing inter-basin water diversion projects in north China in view of local water resources can't meet the demand of socio-economic development and eco-environment protection, and then recommends China's water diversion projects layout in the current and future, which attaching most importance to the South-to-North Water Diversion Project.

There are 109 A class rivers in Japan. One purpose of river management is to reduce the flooding. For this purpose, government provides the information to public, as flood forecasting, rainfall forecasting and estimate the runoff magnitude to avoid the flood and inundation. In this paper, we introduce current situation of flood forecasting and rainfall forecasting in Japan, and we describe how to use the information of flood forecasting and rainfall forecasting in conjunction with current strategy for river management.

Many reservoirs have been constructed for sustainable utilization of water resources in Korea. Effective management of water resources in Korea becomes very important in resent years. Especially, the dredging in reservoirs is important for effective water resources management and one in easy water resources security methods. According to "The reservoir dredging mid-long term planning investigation report", it was investigated that 1221 reservoirs need to dredge among 3,288 reservoirs managed by KARICO. And, KARICO made a survey of reservoirs for the sediment and storage change in $2002{\sim}2004$. In results, it was investigated total storage $1,406{\pm}10^6m^3$, effective storage $1,344{\pm}10^6m^3$ in mid-small 2,748 reservoirs and the storage ratio decreased total storage ratio 15.7%, effective storage ratio 4.4%.
