This study is to think about how to invite a model of culture and arts administrative governance for Blockchain-based Initiative in the nearer future. In particular, it was conceived only in the field of performing arts and was intended to be proposed by referring to the situation in Jeju. Four major governance models were devised. The first is subsidy-related governance. Second, governance related to donations and support, third, governance related to artistic activities, and fourth, governance models for securing customers and resonating between performers were proposed. There are factors to keep in mind to establish governance based on blockchain technology, which is such a future technology. Jeon Myung-san (2017) proposes elements to keep in mind when introducing blockchain technology into the administrative domain in a book called Blockchain Gourbonment. Accepting the proposal, this paper also intends to present matters to be noted in order to build a blockchain gubernator in the conclusion. Among the fields of culture and arts administration, a step-by-step approach will be needed to establish blockchain-based governance of performing culture. First of all, in the first stage, local governments, related organizations, artists, and associations must work on governance construction offline. In the second stage, the blockchain base is learned and governance activities begin within the blockchain base. The third stage should involve citizens as audiences to operate governance.

Stevioside, a natural sweeteners presently used in various kinds of food and food products in Korea, was evaluated for its toxicity potential in the 14 day feeding study using B6C3F1 mice. Stevioside was added to the diet at different concentrations of 0.31, 0.62, 1.25, 2.5 and 5%, and was administered for 14 consecutive days. An increase of liver organ weight in male mice was observed. No diet-related differences were noted in clinical signs, food consumption, and gross and histopatholgical evaluation. Based on these results, we concluded that the concentration of 5% in the diet was a suitable maximum tolerable dose of stevioside for a 90 day study in mice.
