  • The blockchain is still new and unfamiliar. But blockchain appears to shake an entire technology innovation system. Blockchain is rapidly drawing attention in that it will be able to fundamentally revolutionize industry ecosystem. While cryptocurrency transactions and market capitalization have been popular in mass media, several platform operators in non-cryptocurrency areas such as jewelry, social networks, and entertainment, are also moving to introduce blockchain technology in full swing. In this brief note, we intend to present integrated theoretical strands to summarize various prospects for blockchain technology. Further, we want to provide a reflection as to whether this new technology gives opportunities, challenges, or risks to future society. Particularly, we point out one of its alternative and promising adoption that gives way to new forms of decentralized and autonomous organizations (DAOs).

  • This study is written with a purpose to force the changes of way of life in the 21st century through recognizing an environment based on a correct ecological world-view, and to create environmental design of seeing the nature and humans as one organism. This study is focused especially in environmental design and written generally based on urban ecology, human ecology, cultural ecology, and plant ecology with this multi-interdisciplanary approach. To understand meaning of ecosystem by considering the theory of ecology for ecological approach of the environmental design, and to grope for possibility of applying environmental design by considering what to analyze and how to differenciate concept for ecological environmental plan from the mechanical design. Through this study it was realized that the ecological design starts from the recognition of seeing the humans and nature as a one and form being aware of significance of all the living things in our surrounding environment.

  • As most of environmental impacts caused by development projects are irrevocable, a thorough review is utmost necessary. Ecological-economic integrated approach inspired by Norgaard's co-evolution theory should be applied to the environmentally adjusted CBA, which plays a decisive role in the feasibility analysis. Based on case studies of NamHan River Management Project and Yeongsangang Wetland Reclamation Project, this paper attempts to show the usefulness of linking basic plan and implimentation design to EIA and suggests to integrate EACBA into the current EIA system institutionally as a more effective policy tool for realizing sustainable development in Korea.

  • In this paper, we are interested in how creator economy startups allowing creators to make money from doing that they love. So, we look at European creator economy startups among Web3.0 business model landscape surveyed in 2022, because the US is home of Web2.0 giant platforms like YouTube. Totally seventeen European startups are investigated, and the theoretical logic is the disruptive innovation. We firstly review the survey published in 2022 and utilize the theory of the disruptive innovation to design the research framework including questions with each type of the disruptive innovation. In this paper, we firstly show, Kalao and Gem as NFT ecosystem platforms aim at service convenience. Secondly, Talkbase, Passionfroot, Bildr, Customuse, and Earnr aim at providing creator tools for under-skilled customers. Lastly, when it comes direct monetization with a decentralized business model, CrowdPad, Admix, GOALS, Realm, Dropstar, Pianity, Sonomo, Stage11, Miiji, and ReadyPlayerMe are representative. Despite the relatively small data size, the results are meaningful as they contribute to a more profound comprehension of the Web3.0 business models and offer guidance for future research directions.

  • The purpose of this research is to evaluate five types of eco-village planning in order to introduce a landscape unit concept and theory in Korea. Although they had different backgrounds and motives of eco-villages planning, their common goal is to always maintain ecological planning and design in their villages. As concrete methods of ecological planning, we suggest three fundamental planning theories. 1. The boundary of a plan unit should be a watershed. 2. The survey and analysis of village ecotopes should be done in that defined watershed. 3. These results should be applied in the site and lot planning of eco-villages. These 3 steps should be done in a process and relevantly. In the evaluation of the five eco-village planning types, we found three results. 1. On a viewpoint of watershed, most planners recognized a watershed in survey and planning stages unconsciously. But they did not mention watersheds concretely and did not use this concept in the planning stage. 2. They did not define the concept of ecotope, but most planners recognized land-uses and vegetations of villages and vicinities as ecotopes. Also these could be proper ecotopes, but they did not use these compartment of ecotopes in the planning of ecosystem structure in villages. In addition, they did not deeply survey and analyze the ecotopes of villages and its vicinity. 3. On the viewpoint of sites and lots planning, they did not relevantly use the characteristics of watersheds and ecotopes in sites and lots planning. Therefore, they failed to implement the indigenous lots and subdivisions plan. In the size of lots and sites, they did not seriously consider the carrying capacity of ecosystem. We hope that our suggestion about the establishment of eco-villages planning is a fundamental theoretical framework of ecological planning in future eco-village planning.

  • In this work, we analyzed the effects of drought on the water temperature (WT) of Nakdong river basin major river sections using Standardized Precipitation Index (SPI) and WT data. The analysis was carried out on a seasonal basis. After calculating the optimal time scale of the SPI through the correlation between the SPI and WT data, we used the copula theory to model the joint probability distribution between the WT and SPI on the optimal time scale. During spring and fall, the possibility of environmental drought caused by high WT increased in most of the river sections. Notably, in summer, the possibility of environmental drought caused by high WT increased in all river sections. On the other hand, in winter, the possibility of environmental drought caused by low WT increased in most river sections. From the risk map, which quantified the sensitivity of WT to the risk of environmental drought, the river sections Nakbon C, Namgang E, and Nakbon K showed increased stress in the water ecosystem due to high WT when drought occurred in summer. When drought occurred in winter, an increased water ecosystem stress caused by falling WT was observed in the river sections Gilan A, Yongjeon A, Nakbon F, Hwanggang B, Nakbon I, Nakbon J, Nakbon K, Nakbon L, and Nakbon M. The methodology developed in this study will be used in the future to quantify the effects of drought on water quality as well as WT.
