Survival characteristics of food and beverage businesses in a gentrified commercial area-A case study in Seoul, Korea

Commercial gentrification is a common cause of urban transformation in modern cities. Former residential and industrial areas are being transformed into commercial ones specializing in the food and beverage (F&B) industry because of their unique atmosphere. However, F&B businesses in the gentrified commercial areas are prone to intense competition for survival that debate on the emerging commercial street's sustainability. Thus, this study analyzed F&B street businesses' survival characteristics where commercial gentrification has occurred. The research site was selected among Seoul's commercial streets by performing data analysis. The Cox proportional hazards model and urban spatial indicators were used to analyze the factors affecting survival time. The research findings were as follows: First, physical attractiveness, such as openness or visual accessibility, lowered the closure risk. Second, accessibility to cultural facilities or open spaces was beneficial for the nearby F&B demands; however, it occasionally intensified the competition. Finally, competitive businesses' agglomeration increased the closure risk, while non-competitive ones' agglomeration and diversification decreased it. This research's results could be useful for policymakers in promoting a more sustainable business environment for F&B entrepreneurs.

Current status and development prospects of aquatic vaccines

Diseases are a significant impediment to aquaculture's sustainable and healthy growth. The aquaculture industry is suffering significant financial losses as a result of the worsening water quality and increasing frequency of aquatic disease outbreaks caused by the expansion of aquaculture. Drug control, immunoprophylaxis, ecologically integrated control, etc. are the principal control strategies for fish infections. For a long time, the prevention and control of aquatic diseases have mainly relied on the use of various antibiotics and chemical drugs. However, long-term use of chemical inputs not only increases pathogenic bacteria resistance but also damages the fish and aquaculture environments, resulting in drug residues in aquatic products, severely impeding the development of the aquaculture industry. The development and use of aquatic vaccines are the safest and most effective ways to prevent aquatic animal diseases and preserve the health and sustainability of aquaculture. To give references for the development and implementation of aquatic vaccines, this study reviews the development history, types, inoculation techniques, mechanisms of action, development prospects, and challenges encountered with aquatic vaccines.
