Ownership is the bundle of rights that allow a person or institute to use and control an object. As the biomedical science is advanced, we should consider whether human biological material should be recognized as property. Whether separated parts of the human body can be objects of ownership is a different issue. Many thought that separated parts of the human body could not be objects of ownership. This idea is primarily based on this thought: even if a piece of human biological material is separated from a person, it still relates to that person, and if treated as a thing, human dignity may be harmed. However, some commentators have admitted separated parts of the human body into the realm of property. Though a person owns his/her body or body parts, this does not mean that he/she can do anything he/she desires. There are many natural and social limitations to exercise the ownership of human biological material as discussed above. Human dignity is the core consideration whether or not we recognize that ownership of human biological material biomedical research and knowledge.

This paper presents a novel method for minting hierarchical Non-Fungible Tokens(NFTs) via a parent-child structure. In contrast to existing NFT structures, our proposed model enables an NFT to act as a parent, creating child NFTs and distributing ownership stakes among them. These child NFTs are recursively structured, allowing them to generate their own descendants. The existing structure of NFTs does not inherently allow for fractional ownership. However, our proposed hierarchical model provides a feasible solution to this restriction. By dividing an NFT into multiple child NFTs, each with its own unique identity, we facilitate the detailed division of an asset, thereby making fractional ownership possible. In conclusion, the hierarchical NFT model proposed in this paper offers a promising solution to the challenges of fractional ownership in the digital asset arena. By enabling the detailed division of NFTs through a parent-child structure, we anticipate a future where digital assets can be owned and traded more flexibly and transparently.

대체 불가능 토큰 (NFT, non-fungible token)은 고유하고 더 이상 분할할 수 없는 특성을 가지고 있다. NFT 는 디지털 콘텐츠에 대한 소유권을 증명해 주지만 현재 1) 소유권 증명 이상의 유틸리티가 명확하지 않고, 2) 토큰이지만 유동성이 거의 없으며, 3) 가격이 예측 불가능하다. 특히, 부동산의 경우 가격이 매우 높은 특징으로 인하여 투자 진입장벽이 매우 높다. NFT 분할을 하면 유동성의 증가, 그리고 접근성 증가에 따른 커뮤니티 볼륨의 증가를 기대해 볼 수 있다. 이러한 특성을 활용하여 기존에 투자하기 어려웠던 부동산을 다양한 기술을 활용하여 쉽게 투자를 할 수 있게 된다. 또한, Black Litterman 모델을 활용하여 보다 여러 종류의 NFT 들에 대한 최적 포트폴리오를 구성할 수 있는 알고리즘을 설계하고 구현하였다.

With the development of information and communication technology, online fractional investment platforms have emerged through the convergence of online platform technology and new investment techniques for asset-backed derivatives. In this study, the concept and previous studies of the online fractional investment platform business, commercialization models and service processes, market status, and pending discussions and alternatives were presented. Recently, the Securities and Futures Commission's decision on securitization of split ownership has become an important guide to the stable business sustainability of platform operators, but academic research is needed according to the current status and case analysis. To identify specific market issues, examples of representative online fractional investment securitization platform businesses such as "MusiCow" for music copyright, "Tessa" based on art, "Kasa" for real estate, "Piece" based on real assets, and "BangCow" for Korean beef shipments were analyzed. Through the case analysis of this study, the characteristics of the business model according to the basic assets of the online fractional investment platform were compared and presented. Since most business models are judged to be securitic, they must comply with the provisions of the Capital Markets Act or be recognized as the target of innovative financial services. From a practical point of view, it is meaningful in that it presented improvement directions that online fractional securitization platform operators should consider and organized institutional considerations for investor protection.

The software industry is so important to the 21C information society Not only the digital content control but the technology of software source code for the intellectual property is so much mean to international competition. On occurring disputation property of software source code, we have to prove the fact, there is a problem to discriminate the original software source code. In this paper, we make a study of the digital licence prototype for discriminate the original source code. Reserved words of software source code by parsing express to XML file that have hierarchical structure. Then, we can express node pattern and architecture pattern of software source code by tree structure form instead of complex software source code. And we make a simulation of discrimination possibility of digital license and propose CRYPTEX model.

Building Information Modeling, and its associated work practices, requires project participants to share not only 3D geometric data, but also information in the model that may be considered proprietary and even trade secrets. Thus protection of intellectual property, or BIM copyrights, must be in place for participants to share proprietary information among project stakeholders. Currently Korea does not have adequate copyright laws or mechanisms to provide such protection. This research examined three BIM copyright legal documents, namely U.S.' ConsensusDOCS 301, AIA Document E203/G202, and U.K.'s CIC BIM Protocol to determine how copyright protection is realized, and to formulate appropriate stipulations within the Korean construction context. The resultant requirements include stipulating ownership at to the BIM originator, adopting a license-sublicense scheme, employing a federated model, and use of a formal model delivey table to allocate responsibilities. Given Korea's adoption stage, liability should be minimal, and license revocation should be allowed if payments are not met. The three BIM legal documents focus on practical measures that allow participants to customize requirements for individual projects, and such conventions should be emulated in Korea.

We designed a role-based access control model that can resolve the complicated tasks of control requirements. The designed access control model can control permissions efficiently use of a role-based access control. It guarantees the confidentiality integrity and availa information making use of identity-based and rule-based access controls. It can also centre information flow. Our access control model protects resources from unauthorized accesses b multi-level security policies such as role, security level, integrity level and ownership.
