Green New Deal (GND) proposals are suggested as a solution to cope with climate emergency, economic recession, and social inequality. This study aims to conceptualize GNDs through the political questions of who gets what, why, and how. This research defines the politics of GND as a government's stimulus policy to tackle climate change, economic downturn, and inequality by building up sustainable infrastructure, industries, and communities through investment, job creation, and innovation. The politics of the GND framework consists of actors, aims, contents, and measures. By applying this framework, empirical analyses examine the similarities and differences in the GND proposals of the EU and the US. This finding suggests that varying comprehensiveness and concreteness are presented in these proposals. The preliminary analysis demonstrates that measures for funding should be identified for implementing effective GND plans. Research applying the political analysis framework into recently announced Korean GND would contribute to enhancing the policy plan and implementation process.
In a roll-to-roll (R2R) system, the roller’s traction force for precision transportation is crucial for the commercialization of printed electronic devices. Moreover, greater traction force of the roller can prevent several issues, such as slippage, wrinkles, sagging, and air entrainment, which occur because of insufficient traction force. The wrap angle, tension, and friction coefficient between the roller and the transporting film are key factors for achieving greater traction force in an R2R transport system. However, design of the wrap angle and tension are limited by the film damage and complex arrangement of the rollers. For these reasons, this study focused on the method that increases the friction coefficient on the surface of the roller. We applied three methods—normal force, static electricity, and thin polydimethylsiloxane coating—on the surface of the roller. Then, we suggest an effective means of improving the friction coefficient to supplement the design restrictions of tension and the wrap angle in R2R transport systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
