Among the many foods, it is hard to find perfect food with nutrition and functionality like beans. Korean food culture is the main ingredient of korean culture, kochujang, soybean paste, and soy sauce, and processed soybean tofu is the main ingredient. Soybean meets high quality protein and fat, and it has excellent results in prevention and treatment of all kinds of diseases. Soybean food is becoming a new generation health food. In countries where animal protein intake is low, soybean is used as a protein source instead of animal protein. Tofu, a processed food, is a complete food with high digestibility. In order to publicize the superiority of soybean nutritional value, Tofu processing and powder were investigated by observing the size, shape and characteristics of bean powder using domestic soybeans and imported soybean, and the variation of the amount of coagulant.

Bioelectrochemical systems (BESs) have been suggested as a new technology for wastewater treatment while accomplishing energy and chemical generation. This study describes the performance of BESs based on mixed culture that are capable of reducing carbon dioxide to acetate. The cathode potential was a critical factor that affected the performance of the BESs. The rate of acetate production increased as the electrode potential became more negative, from 0.38 mM $d^{-1}$ (-900 mV vs. Ag/AgCl) to 2.35 mM $d^{-1}$ (-1,100 mV), while the electron recovery efficiency of carbon dioxide reduction to acetate increased from 53.6% to 89.5%. The microbial population was dominated by relatives of Acetobacterium woodii when a methanogenic inhibitor was added to the BESs initially.

Recently, research is being conducted on the rapid service provision and reliability of the instance-based rather than the existing IP-based structure. Research is mainly conducted through Block cloud, a platform that combines service-centric networking (SCN) and blockchain. In addition, the Internet of Things network has been proposed as a fog computing environment in the structure of the existing cloud computing. Fog computing is an environment suitable for real-time information processing. In this paper, we propose a new Internet network structure based on fog computing that requires real-time for rapid processing of IoT services. The proposed system applies IoTA, the third-generation blockchain based on DAG, to the block cloud. In addition, we want to propose a basic model of the object block chain and check the application services of electric vehicles.

Despite considerable advancements achieved using next-generation sequencing technologies in exploring microbial diversity, several species of the gut microbiome remain unknown. In this transformative era, culturomics has risen to prominence as a pivotal approach in unveiling realms of microbial diversity that were previously deemed inaccessible. Utilizing innovative strategies to optimize growth and culture medium composition, scientists have successfully cultured hard-tocultivate microbes. This progress has fostered the discovery and understanding of elusive microbial entities, highlighting their essential role in human health and disease paradigms. In this review, we emphasize the importance of culturomics research on the gut microbiome and provide new theories and insights for expanding microbial diversity via the optimization of cultivation conditions.

In today's fashion Street is a birthplace of new generation fashion and Street Fashion have frequently influenced on high fashion. From this view point this study is a meaningful approach to forecast future fashion trend by examining the street style of youth who are regarded as Street Fashion leaders. The purpose of this study is to examine the Youth Fashion style in early 1990s and to pro-vide a reference to fashion designer and mer-chandiser in trend forecasting and product plan-ning. This study is focused on 1990s Youth Fashion style through the historical Street Fashion : 1950s Teddy boys & Mods 1960s Hippies & Skinhead and 1970s Punk. There were mainly two popular Street Fashion phenomena in early 1990s. There were mainly two popular Street Fashion phenomena in early 1990s. One is grunge fashion created by new gener-ation in opposition to existing generation society and impacting on hish fashion leaders. The other is Remix style that is mixed : sub culture fashion originated by young group in 1950-1970s with 1990s sensitivity. Both fashion styles origionated and led by youth of street have influenced on famous high fashion designeres as well as the general public. Street Fashion will continue to play an import-ant role in future fashion and more study and interest on Street Fashion should be taken by fashion forecaster and related.

The coastal marine ecosystems of Vietnam are one of the global biodiversity hotspots, but the biodiversity of marine fungi is not well known. To fill this major gap of knowledge, we assessed the genetic diversity (ITS sequence) of 75 fungal strains isolated from 11 surface coastal marine and deeper waters in Nha Trang Bay and Van Phong Bay using a culture-dependent approach and 5 OTUs (Operational Taxonomic Units) of fungi in three representative sampling sites using next-generation sequencing. The results from both approaches shared similar fungal taxonomy to the most abundant phylum (Ascomycota), genera (Candida and Aspergillus) and species (Candida blankii) but were different at less common taxa. Culturable fungal strains in this study belong to 3 phyla, 5 subdivisions, 7 classes, 12 orders, 17 families, 22 genera and at least 40 species, of which 29 species have been identified and several species are likely novel. Among identified species, 12 and 28 are new records in global and Vietnamese marine areas, respectively. The analysis of enzyme activity and the checklist of trophic mode and guild assignment provided valuable additional biological information and suggested the ecological function of planktonic fungi in the marine food web. This is the largest dataset of marine fungal biodiversity on morphology, phylogeny and enzyme activity in the tropical coastal ecosystems of Vietnam and Southeast Asia. Biogeographic aspects, ecological factors and human impact may structure mycoplankton communities in such aquatic habitats.
