Purpose This study aims to introduce a Smart-Platform for solving numerous problems in urban cities and improving citizens' convenience. This Smart-Platform is achieved by studying the City Data Hub technology to build and spread a Smart City Data Hub . Design/methodology/approach In this study, we analyzed the functions in detail and interlocking flows specific to the published City Data Hub module and designed a Smart-Platform with additional UI-based functions to improve users' convenience based on our previous experience. Findings The City Data Hub will provide a modular data hub platform functionality for application by different stakeholders. However, further research on detailed functionality and experience in interworking legacy systems will be required to apply the platform realistically. Therefore, we judged that this Smart-Platform, which supplements the City Data Hub with additional functions, would be useful for utilizing the City Data Hub in the future. Through the demonstration of the platform designed, it is also necessary to explore the direction of continuous development for the future.

Although subcellular localization and substrate specificity of thioredoxin isoforms have been characterized, there is little information on the specific functions of mtype plant thioredoxins or their interaction targets. Here, we describe the functional characterization of an Oryza sativa thioredoxin m (OsTrxm). We undertook yeast twohybrid screening using OsTrxm as a bait and found three interaction proteins, Pex14 and two Pex5 variants. Furthermore, two cysteines of OsTrxm were sufficient for the interaction between OsTrxm and these peroxisome proteins. To verify whether OsTrxm and the target proteins can be co-localized in vivo, we examined subcellular localization of OsTrxm-GFP and a peroxisomal marker RFP-SKL in Arabidopsis protoplast cells. Surprisingly, we detected OsTrxm localization in the cytosol and chloroplast. We confirmed these results by 2-D PAGE and Western blot analysis. Our results indicate that OsTrxm may play important roles in the cytoplasm for peroxisome biogenesis as well as in redox regulation of chloroplast proteins.
