  • In this paper, we propose a highly secure technique to hide confidential data in image pixels using a quadruple encryption techniques. In the proposed technique, the boundary surface where the image outline exists and the flat surface with little change in pixel values are investigated. At the boundary of the image, in order to preserve the characteristics of the boundary, one bit of confidential data that has been multiply encrypted is spatially encrypted again in the LSB of the pixel located at the boundary to hide the confidential data. At the boundary of an image, in order to preserve the characteristics of the boundary, one bit of confidential data that is multiplely encrypted is hidden in the LSB of the pixel located at the boundary by spatially encrypting it. In pixels that are not on the border of the image but on a flat surface with little change in pixel value, 2-bit confidential data that is multiply encrypted is hidden in the lower 2 bits of the pixel using location-based encryption and spatial encryption techniques. When applying the proposed technique to hide confidential data, the image quality of the stego-image is up to 49.64dB, and the amount of confidential data hidden increases by up to 92.2% compared to the existing LSB method. Without an encryption key, the encrypted confidential data hidden in the stego-image cannot be extracted, and even if extracted, it cannot be decrypted, so the security of the confidential data hidden in the stego-image is maintained very strongly. The proposed technique can be effectively used to hide copyright information in general commercial images such as webtoons that do not require the use of reversible data hiding techniques.

  • Objectives: Underpinned by the context of a Korean traditional medicine cohort study on healthy aging, this research primarily aims to guide the selection of Clinical Outcome Assessments (COAs) for elderly healthy aging patient registry research, offering insights into the selection process; and secondly, to streamline the resource-intensive process of obtaining permissions for validated COAs, benefiting future traditional Korean medicine clinical researchers. Methods : In this study, we identified outcomes through a review of previous studies, followed by a process involving expert consultations to select the final outcomes. Subsequently, for the selected outcomes that were Clinical Outcome Assessments (COAs) developed tools, we searched in commercial databases to confirm the availability of Korean versions and the necessity of obtaining permissions. Finally, we obtained permissions for their utilization and, when needed, acquired the original instrument questionnaire through payment. Results: Through a literature review of existing observational studies, a total of 57 outcomes were selected, with 19 of them identified as COA instruments. Upon verifying usage permissions for these 19 instruments, it was found that 17 required author-specific permissions, and among these, 2 needed a purchase as they were commercially available. Conclusion: This study provides a detailed overview of outcome selection and permission acquisition for elderly patient registry research. It underscores the importance of Clinical Outcome Assessment (COA) tools and the rigorous approval process, aiming to enhance research reliability. Continuous verification of COA information is essential, and future research should explore Core Outcome Set (COS) development through consensus-building approaches like Delphi studies.

  • Academic libraries are at the forefront of supporting their parent institutions in teaching and learning, research activities, and community services for the students and faculty members, but, the researchers observed that some of the research emanating from faculty members in academic institutions particularly universities remains largely unknown, unrecognized and invisible on the global scene. This present paper is therefore a modest attempt towards addressing the issue of enhancing the faculty research visibility in the institutions of higher learning by the academic libraries. It also examines the extent academic libraries in public universities in Nigeria use research visibility channels to increase the global visibility of their faculty members. Difficulties encountered by librarians and ways of tackling the visibility of the faculty were also examined. A descriptive survey research design was adopted and the population consisted of all the 162 librarians in public universities in South-East (S.E), Nigeria. Telephone calls and Online Questionnaire were used for data collection. The number of librarians was obtained through phone calls from the Heads of each of the Libraries. The Online Questionnaire was submitted to the WhatsApp platforms of librarians in Nigeria- Academic and Research Libraries (ARL) and Chartered Librarians in Nigeria Connect (CLN-Connect). The questionnaire was structured in such a way that only the Librarians in Public universities in the S.E. Nigeria will respond to it. At the end of the day only 120 librarians responded, at a response rate of 74%. The study was analysed using tables, percentages and charts. The study recommended that librarians who are unaware of RVCs and its utilization should go for training to acquire the knowledge that will enable them enhance the global visibility of faculty staff, Management of Public universities in S.E, Nigeria should in addition to addressing copyright issues by the use of disclaimer notices and creative common licensing and provision of infrastructural facilities e.g. steady power supply, High power brand Internet connectivity, establishment of an Institutional Repository, etc, also should mandate the faculty staff to release their productive work to the library for onward submission to the RVCs platforms for enhancement of their global visibility.

  • Software is expensive, labor-intensive, and time-consuming to develop. To solve this problem, many organizations turn to publicly available open source, but they often do so without knowing exactly what they're getting into. Older versions of open source have various security vulnerabilities, and even when newer versions are released, many users are still using them, exposing themselves to security threats. Additionally, compliance with licenses is essential when using open source, but many users overlook this, leading to copyright issues. To solve this problem, you need a tool that analyzes open source versions, vulnerabilities, and license information. Traditional Blackduck provide a wealth of open source information when you request the source code, but it's a heavy lift to build the environment. In addition, Fossology extracts the licenses of open source, but does not provide detailed information such as versions because it does not have its own database. To solve these problems, this paper proposes a version and license detection tool that identifies the open source of a user's source code by measuring the source code similarity, and then detects the version and license. The proposed method improves the accuracy of similarity over existing source code similarity measurement programs such as MOSS, and provides users with information about licenses, versions, and vulnerabilities by analyzing each file in the corresponding open source in a web-based lightweight platform environment. This solves capacity issues such as BlackDuck and the lack of open source details such as Fossology.

  • At a time when interest in the educational use of ChatGPT is increasing, it is necessary to investigate the perception of ChatGPT among college students. A survey was conducted to compare the current status of internet and interactive artificial intelligence use and perceptions of ChatGPT after using it in the following courses in Spring 2023; 'Family Life and Culture', 'Fashion and Museums', and 'Fashion in Movies' in the first semester of 2023. We also looked at comparative analysis reports and reflection diaries. Information for coursework was mainly obtained through internet searches and articles, but only 9.84% used interactive AI, showing that its application to learning is still insufficient. ChatGPT was first used in the Spring semester of 2023, and ChatGPT was mainly used among conversational AI. ChatGPT is a bit lacking in terms of information accuracy and reliability, but it is convenient because it allows students to find information while interacting easily and quickly, and the satisfaction level was high, so there was a willingness to use ChatGPT more actively in the future. Regarding the impact of ChatGPT on education, students said that it was positive that they were self-directed and that they set up a cooperative class process to verify information through group discussions and problem-solving attitudes through questions. However, problems were recognized that lowered trust, such as plagiarism, copyright, data bias, lack of up-to-date data learning, and generation of inaccurate or incorrect information, which need to be improved.

  • This paper summarizes the legal problems and issues raised in relation to generative AI. In addition, we looked at what regulatory discussions individual countries or international organizations have in order to solve or respond to these issues or to minimize the risks posed by generative AI. Infringement of individual basic rights raised by generative AI, the emergence and control of new crimes, monopolization of specific markets and environmental issues are mainly discussed, and although there are some differences in the necessity and direction of regulation, most countries seem to have similar views. Regarding AI, the issues that are currently being raised have been discussed continuously from the beginning of its appearance. Although certain issues have been discussed relatively much, there are some differences between countries, and situations that require consideration of phenomena different from the past are emerging. It seems that regulations and policies are being refined according to the situation of individual countries. In a situation where various issues are rapidly emerging and changing, measures to minimize the risk of AI and to enjoy the utility and benefits of AI through the use of safe AI should be sought. It will be necessary to continuously identify and analyze international trends and reorganize AI-related regulations and detailed policies suitable for Korea.

  • This study aims to analyze the regulations and actual operation status related to IR operations for eight institutions participating in the OAK project to examine the need to establish an IR operation policy and the components of an operation policy. The results showed that IR management policies need to include collection and disclosure of research results, copyright management, whether to support APC, and management plans for each type of research result. In particular, clear regulations on the collection and disclosure of research outputs are essential to ensure consistency and efficiency in IR operations. In addition, it is necessary to create an institutional foundation for researchers to share research outputs through OA publication by converting the publication fee support policy of many institutions to a support policy for OA publication. In addition, there are differences in IR management methods depending on the characteristics of each institution, and it is necessary to establish customized IR management policies that fit the characteristics of each institution. In this regard, OAK should provide standardized guidelines and technical support to facilitate the development of IR management policies for each institution. This study can be used as a basis for establishing IR management policies for domestic organizations.

  • 지적재산권의 속지주의 원칙에 따라 전통적으로 지적재산권의 침해에 있어서 결과의 발생이 없는 행위지를 침해지로 인정하지 않았다. 어문과 예술작품을 보호하기 위해 1886년 체결된 베른협약(Berne Convention for the Protection of Literary and Artistic Works) 제5조 제1항은 저작자가 베른협약에 따라 보호되는 저작물에 관하여 본국 이외의 동맹국에서 각 법률이 현재 또는 장래에 자국민에게 부여하는 권리 및 이 협약이 특별히 부여하는 권리를 향유한다고 규정하여 내국민대우원칙을 천명하고 있다. 또한 베른협약 제5조 제2항은 저작권의 보호와 향유는 저작물의 본국에서 보호가 존재하는 여부와 관계가 없이, 보호의 범위와 저작자의 권리를 보호하기 위하여 주어지는 구제의 방법은 오로지 보호가 주장되는 국가의 법률의 지배를 받는다라고 규정하여 저작권 침해가 발행한 국가의 법률의 적용을 명시하고 있다. 인터넷과 무선통신 기술의 발달은 저작물을 디지탈 형식으로 실시간에 전세계에 배포하는 것을 가능하게 하였다. 특히 저작물의 인터넷상에서의 배포는 다국적 저작권 침해행위를 야기하여, 저작권자가 다수의 국가에서 저작권 침해소송을 제기하여 판결을 집행하는 것이 필요하게 되었다. 헤이그국제사법회의(Hague Conference on Private International Law)에서 1992년부터 논의되어 온 민사 및 상사사건의 국제재판관할과 외국판결에 관한 협약(Convention on Jurisdiction and Foreign Judgment in Civil and Commercial Matters)에서 채택된1999년의 예비초안(preliminary draft) 및 2001년 외교회의에서 수정된 잠정초안(Interim text) (이하 헤이그 협약 )은 저작권자가 저작권침해행위가 발생한 각 국가에서 저작권 침해행위를 금지하는 소송을 제기할 필요없이, 동 협약의 한 가맹국가의 법원의 저작권침해금지판결을 다른 가맹국가에서도 집행할 수 있는 가능성을 제시해 주는데 의미가 있다. 헤이그 협약 제10조는 불법행위(torts)에 관한 일반적인 재판관할에 관한 규정을 두고 있으며, 저작권침해에 관한 분쟁은 동 조항의 적용을 받는다. 제10조에 의해 당사자는 가해행위지 국가의 법원 또는 결과발생지 국가의 법원에서 소송을 제기할 수 있다. 결과발생지의 경우 제10조 1항 (b)는 피고가 자신의 행위가 본국의 법규에 비추어 동일한 성격의 손해를 초래할 수 있다라고 합리적으로 예견할 수 없었던 경우에 본 조항의 적용을 배제하고 있다. 인터넷을 통한 저작권침해의 경우, 피고가 자신의 국가의 법규하에서 합법적으로 저작물을 웹사이트에 게시하였으나, 그 행위가 다운로딩이 행해진 국가에서 불법인 경우, 피고는 저작권침해를 예견할 수 없었으므로 이에 문제가 제기된다. iCrave TV사건에서, 피고인 캐나다회사가 미국 및 캐나다에서 방송되는 텔레비젼 방송 프로그램을 자신의 웹사이트에 게시하여 이용자들로 하여금 컴퓨터를 통하여 방송을 재시청 할 수 있도록 하였는데 이는 캐나다에서 합법인 반면에 미국에서는 저작권 침해에 해당한다. 피고는 방송 프로그램을 인터넷상에서 재방송하는 것은 캐나다법상 합법이므로 저작권침해를 예견할 수 없었다고 주장하면서, 해당 사이트에 오직 캐나다 거주자만의 접속을 허용하고 미국 거주자의 접속을 제한하는 일련의 Click-Wrap 계약과 스크린 장치를 제공하였다고 주장하였다. 본 사건 피고의 주장을 받아들인다고 가정할 때, 제10조 1항(b)에 의해 원고는 결과발생지인 미국법원의 재판관할을 강제할 수 없을 것이다. 지적재산권을 둘러싼 분쟁에 관한 재판관할과 국제법상의 판결의 승인 및 집행의 통일성을 기하기 위하여 2001년 1월 세계지적재산권기구(World Intellectual Property Organization)가 제안한 WIPO 협약초안(Draft Convention on Jurisdiction and Recognition of Judgments in Intellectual Property Matters)은 헤이그 협약이 재판관할과 판결의 승인 및 집행에 대한 일반적인 접근을 하고 있는 점에 반하여 지적재산권자의 보호라는 측면을 고려하여 지적재산권침해소송에 국제재판관할권을 규정하고 있다. WIPO 협약초안 제6조는 저작권자가 저작권 침해를 막기 위한 합리적인 조치를 취한 국가에서 저작권 침해소송을 피할 수 있다고 규정하고 있다. 따라서 본 조항에 의할 경우, iCrave TV사건의 피고는 미국에서의 저작권 침해소송을 회피할 수 있을 것이다. 이상과 같이 헤이그 협약이 외국판결의 승인 및 집행을 가능하게 하고 있음에도 불구하고, 외국법원의 판결이 다수의 가맹국가에서 집행되지 못하는 가장 큰 장애는 대다수의 국가들이 외국법원의 판결이 공서양속(Public Policy)에 반하는 경우 판결을 승인하지 않는 예외규정을 두고 있기 때문이다. 미국의 경우, Uniform Recognition Act와 Restatement(Third) of Foreign Relations에 따른 공서양속의 예외규정(Public Policy exception)은 외국법원의 판결의 승인을 부인하는 근거가 된다. Yahoo! 사건에서 Yahoo! Inc.의 옥션 사이트를 통해 독일 나치 소장물의 판매가 이루어졌는데, 프랑스 형법상 이는 범죄행위에 해당하므로, 프랑스 법원은Yahoo! Inc.에게 프랑스 이용자가 당해 옥션 사이트에 접속할 수 없도록 모든 가능한 조치를 취할 것을 명하였다. 이에 미국 법원은 프랑스 법원의 판결은 Yahoo! Inc.의 미국헌법 제1 수정(First Amendment)의 언론의 자유(freedom of speech)에 반하므로 판결의 집행을 거부하였는데 이는 공서양속의 예외규정을 보여주는 예이다. 헤이그 협약 제28조와 WIPO 협약초안 제25조 또한 공서양속의 예외규정을 두고 있다. 본 논문은 인터넷과 통신기술의 발달로 야기되는 다국적 저작권 침해사건에서 한 국가의 법원의 저작권 침해금지판결이 다수의 국가에서 승인 및 집행될 수 있는 능성을 헤이그 협약과 WIPO 협약초안 및 미국판결을 중심으로 살펴보았다. 국제적으로 통일된 저작권법이 존재하지 않고 외국 판결의 승인을 부인하는 예외조항과 외국판결의 집행에 관한 각국의 이해관계와 준거법의 해석이 다른 현시점에서 지적재산권의 속지주의를 뛰어넘어 외국법원의 판결을 국제적으로 집행하는 것은 다소 어려움이 있어 보이나 국제적인 집행가능성의 열쇠를 제시하는 헤이그 협약과 장래의 국제조약에 그 기대를 걸어볼 수 있겠다.

  • Recently, the shrunk influence of printed cartoon has been superseded by the influence of Webtoon in the comic industry. Webtoon has gained popularity and interest by being served on internet quickly and easily. Their novel material and sympathetic topic have made it possible for many Webtoons to be reproduced into tv dramas and movies, so, the influence of them has been increased as the copyright industry of culture contents industry. The increasing interest for Webtoon has induced academic studies for the subject. Among the various studies in need on Webtoon, the most important study topics in need are 'Story' and 'Quality' which are criterion for readers to choose Webtoons to read. To create the Webtoon that are great at 'Story' and 'Quality', the study on plots should be preceded, which recast episodes organically through a logical causal relationship. Therefore, in this study, the plots of Webtoons have been analyzed through Rescue plot in and the Riddle plot in selected from the Kang Full's Webtoon series, 'mystery psychology horror season', which are evaluated as the great work at 'Story' and 'Quality.' The analysis was implemented based on Tobias' theory which suggests 'the characteristics of plot' and '8 principles for good plot.' First, Kang Full's webtoons were analyzed through 'the characteristics of plot' and '6 principles for good plot' which is modified from '8 principles of good plot' based on Tobias' theory. Applicability was checked if Tobias' theory could be applied to Kang Full's Webtoon checking through the scenes and contents of the Webtoon. (1) Tobias' 'the characteristics of plot' could be applied to both Rescue plot in and the Riddle plot in . (2) Among '6 principles for good plot', 5 principles are shown in The Lighting Store and all of the 6 principles in Neighbor. The result shows that Tobias theory could be applied to the plot of Webtoon. The fact that Kang Full's Webtoons are composed in a formulaic form could be identified through 'the characteristics of plot' and '6 principles for good plot' shown in Rescue plot in and the Riddle plot in .

  • Watermarking is a widely employed method tn protecting copyright of a digital image, the owner's unique image is embedded into the original image. Strengthened level of watermark insertion would help enhance its resilience in the process of extraction even from various distortions of transformation on the image size or resolution. However, its level, at the same time, should be moderated enough not to reach human visibility. Finding a balance between these two is crucial in watermarking. For the algorithm for watermarking, the predefined strength of a watermark, computed from the physical difference between the original and embedded images, is applied to all images uniformal. The mean brightness or contrast of the surrounding images, other than the absolute brightness of an object, could affect human sensitivity for object detection. In the present study, we examined whether the detectability for watermark noise might be attired by image statistics: mean brightness and contrast of the image. As the first step to examine their effect, we made rune fundamental images with varied brightness and control of the original image. For each fundamental image, detectability for watermark noise was measured. The results showed that the strength ot watermark node for detection increased as tile brightness and contrast of the fundamental image were increased. We have fitted the data to a regression line which can be used to estimate the strength of watermark of a given image with a certain brightness and contrast. Although we need to take other required factors into consideration in directly applying this formula to actual watermarking algorithm, an adaptive watermarking algorithm could be built on this formula with image statistics, such as brightness and contrast.
