Purpose - The purpose of this paper is to examine the buyer's right to avoid the contract under SGA and CISG. Design/methodology/approach - This paper has conducted literature reviews to analyze the right to avoid the contract of the buyer based on the comparative study. Findings - Under s. 11(3) of SGA, the breach of a condition and an intermediate which deprives the buyer substantially of the whole benefit of the contract may give rise to a right to treat the contract as repudiated. But under Art. 49 of CISG, the buyer has the right to terminate the contract where the seller's failure to performance amounts to a fundamental breach of contract. Regarding the breach of an intermediate and the breach under CISG, the buyer should take into account where the seller's breach is fundamental or not. Moreover, an anticipatory breach can give rise to a right to avoid the contract. The anticipatory breach of a condition justifies termination. The breach of an intermediate and the breach under CISG require an anticipatory fundamental breach of the contract. Under SGA, the buyer has to prove an anticipatory breach in fact but CISG does not require virtual certainty, which SGA has stricter criteria to assess an anticipatory breach. Research implications or Originality - Comparative study helps to understand the nature of provisions under SGA and CISG and suggests practical advice to choose applicable laws. SGA gives more certainty to classify a contractual term. In case of the breach of a condition including the anticipatory breach under SGA, the buyer does not have to ask how much serious the breach is. But CISG requires the fundamental breach of the contract, which means that the buyer has the more burden of proof compared with SGA.

In this paper, we empirically evaluate the potential performance of energy conversion policy and analyze its effects on power generation sector. We first examine the degree of substitutability between energy inputs by measuring the price elasticities of energy demands and then estimate the changes in CO₂ generation when the proportions of nuclear power plants and renewable power generation are increased. The shadow prices of nuclear power and renewable energy are calculated to compare the potential costs of power generation between the two energy sources. We analyze the impacts of the expansion of nuclear power plants and renewable power generation on power supply price. Nuclear and renewable energy were measured to be complementary to each other. The expansion of nuclear power plants has been more effective in reducing CO₂ emissions than increasing renewable power generation. In most years over 2002 to 2016, the impact of nuclear power expansion on the power supply price was generally higher than that of renewable power generation, with relatively large range of fluctuations.

Since the recent COVID-19 pandemic, countries have been strengthening trade protection for their security, and the importance of securing strategic materials, such as food, is drawing attention. In addition to the cultural aspects, the global preference for food produced in Korea is increasing because of the Korean Wave. Thus, the Korean food industry can be developed into a high-value-added export food industry. Currently, Korea has a low self-sufficiency rate for foodstuffs apart from rice. Korea also suffers from problems arising from population decline, aging, rapid climate change, and various animal and plant diseases. It is necessary to develop technologies that can overcome the production structures highly dependent on the outside world of food and foster them into export-type system industries. The global agricultural industry-related technologies are actively being modified via data accumulation, e.g., environmental data, production information, and distribution and consumption information in climate and production facilities, and by actively expanding the introduction of the latest information and communication technologies such as big data and artificial intelligence. However, long-term research and investment should precede the field of living organisms. Compared to other industries, it is necessary to overcome poor production and labor environment investment efficiency in the food industry with respect to the production cost, equipment postmanagement, development tailored to the eye level of field workers, and service models suitable for production facilities of various sizes. This paper discusses the flow of domestic and international technologies that form the core issues of the site centered on the 4th Industrial Revolution in the field of agriculture, livestock, and fisheries. It also explains the environmental awareness production technologies centered on sustainable intelligence platforms that link climate change responses, optimization of energy costs, and mass production for unmanned production, distribution, and consumption using the unstructured data obtained based on detection and growth measurement data.

Natural gas is globally emerging as an important energy source for environmental, political and regional reasons. In Korea, natural gas imported from oversea natural gas resources as a LNG, it is increased for an applications as a fuel and feedstock which replace the coal and nuclear energy. Because it is relied on the import market in Korea, it is very important to analyze the security for supply. Therefore, this study suggested a method for reducing supply risk and for providing stable supply and demand through risk analysis of Korea's import structure. In order to reduce the supply risk, the concentration of importing countries should be lowered and it is necessary to lower the proportion of countries with relatively low GSSI and increase the imports from Russia. Finally increasing the number of importing countries or maintaining friendly relations with countries where the supply is stable could give us the positive impact in terms of total GSSI.

For The purpose of this study is to understand the cultural differences between Yemen and Ethiopia for Koreans who love coffee and to find ways to cooperate with the region. The Islamic region is not able to cooperate directly, so we thought about how to exchange through the coffee industry. Therefore, the regional exchange model and prior research were examined. And examined the characteristics of early cultures and religions. We learned about political and regional relations through cultural cooperation and the history of Islamic conflict in Yemen. Finally, the local coffee industry and culture were explained. In conclusion, education is needed for regional cooperation in Islamic studies, and for this purpose, First, overcoming cultural clashes; Second, new strategic regional cooperation, Third, a cultural approach rather than a religion, Fourth, new technological regional cooperation; Fifth, parallel regional cooperation with Yemeni refugees; Sixth, a method such as a bridgehead in Ethiopia (Yemen trade and regional cooperation) was proposed.

Due to increased competition in supply side to reduce operational costs, port professionals have experienced extreme pressure, which demanded academicians to develop the model for efficient port operations from the industry perspective. Among many ports in the world, U.S. ports are our primary interest to analyze in our study for its high volume of cargoes transacted in the U.S. ports. We primarily employed DEA (Data Envelopment Analysis) technique to research the productivity of U.S. ports and applied the algorithm of double bootstrapped DEA proposed by Simar & Wilson (2007) to further investigate the driving forces of the performance of U.S. port operations. The external variables employed in our study comprise onDock Rail, Channel Depth, Location, Area, Acres, ForeignCargoRatio, and TEUChange, out of which onDock Rail, Acres, ForeignCargoRatio, and TEUChange were significant. In order to evaluate the effects of methodology selection, we conducted the same analysis applying the Censored model (Tobit) and contrasted the outcomes drawn from the two different techniques. Based on the findings from this work we proposed managerial implications and concluded.

Unauthorized generations and sales of non-funable tokens (NFTs) without the consent of the creator is one of the biggest problems that arise in NFT Marketplaces. This study proposes a method to practically reduce the problem of NFT sales without the consent of the creator by means of authentication with social media accounts. Through the proposed method, creators who are already using social media as a means of communication and marketing for creative activities can authenticate with their own accounts. Creators who have difficulty authenticating with their own accounts will be provided with alternatives to authenticate using human networks. In addition, the proposed method of protecting creator rights was designed using a flowchart to enable development using only the public API (Application Programming Interface) provided by social media. The proposed method can protect creators' rights and reduce damage caused by NFT fraud by inducing buyers to trade NFTs of authorized sellers through social media.
