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.

The purpose of this study is to introduce a non-fungible token(NFT) for the protection of Gotjawal, and to propose a virtuous cycle of re-donation to a donation organization for the main goal and protection through the auction process. The Gotjawal Trust of Jeju is active in Jeju Island. It started with a problem consciousness to link the NFT to the movement of the Gotjawal Gong Yoo Fire Foundation. It proposed requirements for successful application of NFT to Gotjawal sharing. First, there is a need for a convincing story about why the Gotjawal Shared Fire Foundation entered the NFT market. Second, it is necessary to examine whether there is a reputation of the Gotjawal Gong Yoo Fire Foundation that can be solved by NFT. Third, it is important to develop and promote logic that can guarantee the "future value will continue or increase" of the Gotjawal Shared Foundation NFT. The effects of applying NFT to the protection of Gotjawal are as follows. Securing the reliability of the Gotjawal Foundation Movement, adding the concept of investment to donations, continuing activation of donations through a virtuous cycle structure, connecting donations to ownership, and digitalizing donation certificates to secure objectivity of certification.

This study conducted a survey and evaluation on ‘The 2021 Jeju World Natural Heritage Festival’ with a framework of various stakeholders related to festivals. While aiming for the essential context of the celebration, we tried to find suggestions to ensure the continuity of the celebration and the designation of the World Natural Heritage. As a methodology, surveys and interview surveys were conducted in parallel with the framework of multifaceted evaluation. To summarize the important contents presented as policy suggestions, first, it is necessary to expand the concept of ' encounter with hidden nature' from the positivity of the concept of 'encounter with hidden nature' to have fellowship with mankind about natural heritage. For reference to this, efforts should be made to secure the continuity of the designation of World Natural Heritage through a contextual approach using the frame of 'encounter'. Second, since the participation of experts can help in many ways, it is necessary to encourage many experts to participate as a staff or activist. Third, it is necessary to sublimate Jeju's natural heritage into a public celebration without damaging it. Finally, it should be a festival centered on local communities and local residents. It is necessary to actively seek a system in which the World Natural Heritage Village Preservation Association, which will be created (tentative name), will be centered and promoted by the villagers.

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.
