The development of cloud computing technology and smart devices have increasingly been expanding the influence in various fields. Although DRM(Digital Rights Management) is a very important technology for secure content services, interoperability among DRM technologies must be addressed in order to provide the service without the constraints of time and place on various smart devices. In this paper, we study DRM Cloud which provides DRM functions as a service in cloud computing environment, and address interoperability problem by providing different DRM technologies as a cloud service. That is, when a user wants to play contents with the different DRM technologies on a smart device, the usage of the content is controlled by providing the corresponding DRM module and function as SaaS from DRM cloud. To do this, we define the functions and structure of DRM Proxy which performs smooth service call and provision between DRM cloud user and DRM cloud, and finally we describe the experimental implementation result.

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.

Purpose: This study aimed to identify the factors influencing nursing students' intentions to report child abuse. Methods: The participants of this study were 151 nursing students who were currently enrolled in nursing departments in Korea and who were at least 18 years of age or older. This study used a descriptive cross-sectional design, and the data were collected from February 16, to March 13, 2023, using an online self-administered survey. The questionnaire included general characteristics, empathy ability, child rights recognition, child abuse perception, and intention to report child abuse. The data were analyzed with descriptive statistics, an independent t-test, one-way ANOVA, Scheffé test, and multiple regression analysis using SPSS Statistics 29.0. Results: The intention to report child abuse showed statistically significant positive correlations with empathy ability (r=.23, p<.001), child rights recognition (r=.34, p<.001), and child abuse perception (r=.63, p<.001). In the multiple regression analysis, the factors significantly related to nursing students' intention to report child abuse were as follows: awareness of mandatory reporting (yes) (β=.16, p=.021) and child abuse perception (β=.56, p<.001). The explanatory power of these factors was 45.0% (F=20.03, p<.001). Conclusion: Considering the findings of this study, it is necessary to develop and implement educational programs for improving the perception of child abuse and thus enhancing nursing students' intention to report child abuse.

This paper provides a framework for information assurance within collaborative design, based on a technique we call role-based viewing. Such role-based viewing is achieved through integration of multi-resolution geometry and security models. 3D models are geometrically partitioned, and the partitioning is used to create multi-resolution mesh hierarchies. Extracting a model suitable for access rights for individual designers within a collaborative design environment Is driven by an elaborate access control mechanism.

Information assurance(IA) refers to methodologies to protect engineering information by ensuring its availability, confidentiality, integrity, non-repudiation, authentication, access control, etc. In collaborative design, IA techniques are needed to protect intellectual property, establish security privileges and create "need to know" protections on critical features. Aside from 3D watermarking, research on how to provide IA to distributed collaborative engineering teams is largely non-existent. This paper provides a framework for information assurance within collaborative design, based on a technique we call role-based viewing. Such role-based viewing is achieved through integration of multi-resolution geometry and security models. 3D models are geometrically partitioned, and the partitioning is used to create multi-resolution mesh hierarchies. Extracting an appropriately simplified model suitable for access rights for individual designers within a collaborative design environment is driven by an elaborate access control mechanism.

The importance of design is emphasized in many industries. It began to earn recognition as part of industry rather than the arts. In particular, utilization of visual information design including moving images, packaging, advertisement, publication, editorial and visual information processing is higher than others in the design field. However, disputes relating to intellectual property rights have been also increasing as it became known. Therefore, now is the time to consider and establish an effective dispute settlement system for the design industry. In this view, arbitration will be a suitable method for dispute settlement in visual information design because of characteristics such as confidentiality, professionalism, efficiency, economy and flexibility. However, Arbitration system is not well known to the people who work in this industry. Thus, in order to aggressively advertise the arbitration system, an arbitration institution has to appoint design experts as new arbitrators for domestic and international arbitration. Next, an arbitration institution needs to prepare the new and expediting rules with design field characterization. Finally, it has to plan to cooperate with all of the institutions and schools concerned.

인터넷의 확산과 더불어 디지털 컨텐츠의 유통도 확산되었다. 그러나 디지털 컨텐츠들은 쉽게 원본과 똑같은 품질로 복제할 수 있으며, 인터넷을 통해 빠르게 이동이 가능하고 사용자들은 얼마든지 불법으로 이용할 수 있다는 것이다. 최근 국내·외에서 이러한 문제를 해결하기 위해 디지털 컨텐츠들을 보호하고 관리할 수 있는 DRM 기술이 활발히 연구 중이다. DRM 기술은 암호화 기술을 이용하여 허가되지 않은 사용자로부터 디지털 콘텐츠를 안전하게 보호하고 디지털 컨텐츠 저작권 관련 당사자의 권리 및 이익을 지속적으로 보호 및 관리 할 수 있는 기술이다. 본 논문에서는 저작권 보호를 위해 안전한 DRM 메커니즘을 제안한다.

컴퓨팅 환경이 유리쿼터스 환경으로 변해가면서 다양한 컨텐츠와 다양한 디바이스들이 등장하게 되었고, 디지털 컨텐츠를 보호하기 위해 DRM(Digital Rights Management) 기술이 적용된 서비스가 제공되고 있다. 그러나 현재 DRM 기술의 디지털 컨텐츠 보안 정책은 일정한 키 길이에 동일한 암호 알고리즘을 사용함으로써 비효율적이고, 사용자의 다양한 요구를 만족시키지 못하고 있다. 본 논문에서는 디지털 컨텐츠에 보안 정책을 효율적으로 적용하고 디바이스의 성능과 디지털 컨텐츠의 가치에 따라 의사 결정 방법인 MAUT(Multi-Attribute Utility Theory) 알고리즘을 이용하여 최적의 보안 등급을 동적으로 결정하는 컨텐츠 암호화 모듈을 설계하고 구현한다.

The paper focuses on the clothing codes described in the Analects of Confucius, and explores the reasons for the rules setting up, including the rules of color, the design, the pattern, and even the material of the clothes whose distinct features reflect the ceremony and etiquette of the time in the classic, which are in correspondence with the requirements of Confucianism, especially for stressing the social rights, obligations and codes of conduct to everyone in the society.

디지털 컨텐츠의 생산과 수요가 폭발적으로 증가함에 따라 컨텐츠에 대한 지적 재산권 및 수익 창출에 대한 중요성이 대두되었다. 이를 위해 디지털 컨텐츠 자체에 저작권을 보호살 수 있는 기능을 부여하는 기술인 DRM이 개발되었다. 본 논문에서는 DRM(Digital Rights Management)의 영역에 속하는 디지털 컨텐츠 접근을 제어하기 위한 기술 중에서 이미지 컨텐츠에 대한 불법적인 캡쳐 방지를 위한 모델을 제안한다.
