The study investigates how the presence of blockchain technology affects social fairness and selfish monetary decisions. Based on the assumption that blockchain technology enhances transparency and traceability in social exchanges, the study predicts that individuals will make less selfish decisions when blockchain is present. To test these predictions, the study conducted three experiments using a modified version of the dictator game scenario where participants decide how to divide a sum of money among themselves. In Study 1, the results show that individuals took less money for themselves and allocated more to the third player when blockchain technology was present, and the importance of social fairness was higher under the blockchain-presence condition. The mediation analysis indicates that the increase in social fairness mediates the effect of blockchain technology on monetary decisions. Study 2 replicated Study 1 with real monetary incentives. The results showed that individuals took less money for themselves only under the blockchain-image condition, and the importance of social fairness was higher only under the blockchain-image condition. Study 3 examined the moderating effect of the first player's allocation on participants' behavior under the presence or absence of blockchain technology. The study provides empirical evidence that blockchain technology can positively influence social fairness and reduce selfish monetary decisions. The findings have implications for policymakers and blockchain developers to design and implement blockchain systems that promote transparency and traceability in social exchanges, thereby enhancing social fairness.
EVALUATION OF MULTIPLE VARIATIONS WITH NONFUNGIBLE TOKENS (NFTS): IMPORTANCE OF UNIQUENESS
Jungkeun Kim,Daniel Chaein Lee,Jaehoon Lee,Jihoon Jhang,Jooyoung Park 글로벌지식마케팅경영학회 2023 Global Marketing Conference Vol.2023 No.07
This paper examines how consumers evaluate digital products with multiple Non-fungible Tokens (NFTs), which are blockchain-enabled cryptographic assets that represent proof-of-ownership for digital objects. The study predicts that people prefer fractioned NFTs (unique fractions of a digital object) versus duplicated NFTs (identical digital objects with distinct numbers) due to their preference for uniqueness. The study also examines the moderating role of product attributes, predicting that preferences for fractioned NFTs will be reduced when the product provides unique aspects, such as a serial number.
Obstacle avoidance for small UAVs using monocular vision

<B>Purpose</B> - The purpose of this paper is to propose that the three-dimensional information of obstacles should be identified to allow unmanned aerial vehicles (UAVs) to detect and avoid obstacles existing in their flight path. <B>Design/methodology/approach</B> - First, the approximate outline of obstacles was detected using multi-scale-oriented patches (MOPS). At the same time, the spatial coordinates of feature points that exist in the internal outline of the obstacles were calculated through the scale-invariant feature transform (SIFT) algorithm. Finally, the results from MOPS and the results from the SIFT algorithm were merged to show the three-dimensional information of the obstacles. <B>Findings</B> - As the method proposed in this paper reconstructs only the approximate outline of obstacles, a quick calculation can be done. Moreover, as the outline information is combined through SIFT feature points, detailed three-dimensional information pertaining to the obstacles can be obtained. <B>Practical implications</B> - The proposed approach can be used efficiently in GPS-denied environments such as certain indoor environments. <B>Originality/value</B> - For the autonomous flight of small UAVs having a payload limit, this paper suggests a means of forming three-dimensional information about obstacles with images obtained from a monocular camera.

The market for counterfeit luxury goods is growing rapidly, with estimates suggesting that counterfeit trades are valued at around $4.5 trillion globally, with 60% to 70% of this being made up of counterfeit luxury goods. Research has shown that counterfeits dilute the perceived quality of luxury brands and reduce consumers' purchase intentions. Non-fungible tokens (NFTs) are a form of ownership record that is linked and stored on a blockchain.
The deformation space of real projective structures on the $(^*n_1n_2n_3n_4)$-orbifold
Lee, Jungkeun Korean Mathematical Society 1997 대한수학회보 Vol.34 No.4
For positive integers $n_i \geq 2, i = 1, 2, 3, 4$, such that $\Sigma \frac{n_i}{1} < 2$, there exists a quadrilateral $P = P_1 P_2 P_3 P_4$ in the hyperbolic plane $H^2$ with the interior angle $\frac{n_i}{\pi}$ at $P_i$. Let $\Gamma \subset Isom(H^2)$ be the (discrete) group generated by reflections in each side of $P$. Then the quotient space $H^2/\gamma$ is a differentiable orbifold of type $(^* n_1 n_2 n_3 n_4)$. It will be shown that the deformation space of $Rp^2$-structures on this orbifold can be mapped continuously and bijectively onto the cell of dimension 4 - \left$\mid$ {i$\mid$n_i = 2} \right$\mid$$.
