Purpose: This study is know the home care nursing specialists' copying method for life-threatening emergency situation occurred while changing the tracheotomy tube in the patient's home through case-based learning. Methods: Two cases were analyzed using structured critical reflection while changing the tracheal tube. In the first case, the patient presented with dyspnea, cyanosis, and low oxygen saturation when connected to home mechanical ventilator after replacement of the tracheotomy tube. In the second case, replacement of the tracheal tube was difficult due to a narrowed airway from proliferated granulation tissue. Results: From the case-based learning. using a critical reflection instrument, home care nursing specialists indicated that it was important to explain the possibility of danger to the client and that nurses must check the operation of the ambu-bag to prepare for an emergency when replacing a tracheotomy tube. Moreover, they stated a need for two nurses during client visits when there is the possibility of an emergency. Conclusion: Case-based learning through critical reflection provides actual practice-focused knowledge that is helpful to home care nurse specialists who face emergency situations in a restricted environment. Therefore, we hope that home care nursing specialists will use this method to strengthen their professional knowledge.

The Korea Copyright Commission has pursued copyright technology R&D projects to prevent illegal copying of comics and Webtoons. We developed a feature-based scanned comic filtering technology in order to apply technical measures to specific types of online service providers. We also developed technologies in order to monitor and identify illegally distributed comics on webhard sites and to monitor and identify illegally distributed webtoons. Even though all comic books posted on webhard sites are illegal, it is no trouble to download and access popular comics by accessing websites in foreign countries. Even under these circumstances, the comic and webtoon copyright protection technologies developed over the past six years have been used at all. In this paper, we examine what the problems are and find solutions to propose a copyright protection method for webtoons.

In this study, we propose a logical transfer method of records using cloud storage to solve the integrity problem of digital component, which is generated when electronic records are transferred from the electronic record production system to the record management system. This method, which produces electronic records using cloud storage from the production stage and transfers them to the archives, has the following advantages. First, as a record management method, it can be effectively applied in public institutions by utilizing cloud computing technology, which has been the trend recently. Second, unlike the existing method of copying and physically transferring electronic records, the proposed method can reduce various risk factors that may occur in the transfer of electronic records by logically transferring the storage. Third, the method can prevent errors of the digital component according to the physical transfer of the electronic record; hence, the integrity of the electronic record can be guaranteed. Fourth, administrative power and cost that are wasted because of the electronic transfer of electronic records can be reduced.

Design is a key factor that determines the competitiveness of products in the textile and fashion industry. It is very important to measure the similarity of the proposed design in order to prevent unauthorized copying and to confirm the originality. In this study, a deep learning technique was used to quantify features from images of textile designs, and similarity was measured using Spearman correlation coefficients. To verify that similar samples were actually detected, 300 images were randomly rotated and color changed. The results of Top-3 and Top-5 in the order of similarity value were measured to see if samples that rotated or changed color were detected. As a result, the VGG-16 model recorded significantly higher performance than did AlexNet. The performance of the VGG-16 model was the highest at 64% and 73.67% in the Top-3 and Top-5, where similarity results were high in the case of the rotated image. appear. In the case of color change, the highest in Top-3 and Top-5 at 86.33% and 90%, respectively.

This research aims to reconsider the necessity of an alternative way(s) for contemporary actor training and acting in discussing and articulating Diderot and Suzuki's concepts and approaches for acting/training. First of all, the physical body, assumed and conceptualized by Diderot is beyond our control by means of a type of radical body/mind dualism, and is based on the concept that body and mind are separate. In contrast, Suzuki's notion of acting/training is raised by his concern about the role of an actor's body in the constitution of an actor's bodily experience against the imitation of the West-oriented theatre/acting/training. The descriptions of the two theatre artists' notion of acting/training gives us insight into the place and role of contemporary theatre as a practical root to encounter and communicate between a doer and a spectator where an actor's body must appropriately be attuned and cultivated towards the cultivation of bodily attributes which are foundation but usually neglected by actors/directors/practitioners particularly in Korea. Especially, misunderstanding of a specific training sources/approaches, namely 'scientific system' and the 'method' have taken us away from the potential possibilities of the lived oneness. Here, the 'possibility' refers to the primary bodily functions within a specific context or being in the here and now rather than attempting to copying, imitating and/or adapting a specific cultural source(s)/approaches/techniques as we have faced with through the previous century. We reconsider and argue that a potential way to correspond the nature of theatre/acting/training is that how to meet the demand of contemporary spectators which in turn intensifies an actor's stability, sustainability and hopefully professional identity in this contemporary era.

When the owners of the intellectual property rights of digital content have lost control over it in the digital environment, there emerged fears that the intellectual property laws, especially copyright law, would not be effective as in the material (Offline ) world. The reason is that the digital environment helps to reproduce copies in high quality and at almost no cost, while copyright law protection has been limited to programs embedded in CDs. According to copyright laws, the owner of the program did not have the right to prevent buyers of the initial physical copy of the program from copying and reselling it to more than one individual without the permission of the original owner. As a result, business owners have invented the idea of licensing digital content and programs instead of selling them. They set out terms that serve their commercial interests regardless of their abuse to intellectual property laws or even the rules of the traditional contract to sell a material property. The abuse has resulted from the way those terms are concluded and the heavy rules that are unfair to consumer rights. Therefore, business owners insisted on dealing with the website and its programs and digital content as material property. Here raises the question of whether the website and its digital content are subject to the protection of copyright law or the rules of the traditional contract or licensing contracts. As the answer to this question affects the protection of consumer rights, is it possible to find a balance between it and the protection of the owners of digital programs' rights.That is what we will discuss in this paper.

Due to the rapid progress in network technology, many research on content security technologies is also being conducted in the mobile digital content sector. In the meantime, content protection has been immersed in preventing illegal copying, certifying, and issuance/management certificates, but still have many vulnerabilities in managing or authenticating confidential information. This study aims to strengthen confidential information about content based on dual management of content download rights through mobile phone numbers or device numbers. It also protect replay-attack by building a secure mobile DRM system where digital content is safely distributed based on a three-stage user authentication process. In addition, blockchain-based content security enhancements were studied during the primary/secondary process for user authentication for the prevention of piracy and copyright protection. In addition, the client authentication process was further improved through three final stages of authorization in the use of illegal content, considering that legitimate users redistributed their content to third-party.

The state-of-the-art video-based point cloud compression(V-PCC) has a high efficiency of compressing 3D point cloud by projecting points onto 2D images. These images are then padded and compressed by High-Efficiency Video Coding(HEVC). Pixels in padded 2D images are classified into three groups including origin pixels, padded pixels and unoccupied pixels. Origin pixels are generated from projection of 3D point cloud. Padded pixels and unoccupied pixels are generated by copying values from origin pixels during image padding. For padded pixels, they are reconstructed to 3D space during geometry reconstruction as well as origin pixels. For unoccupied pixels, they are not reconstructed. The rate distortion optimization(RDO) used in HEVC is mainly aimed at keeping the balance between video distortion and video bitrates. However, traditional RDO is unreliable for padded pixels and unoccupied pixels, which leads to significant waste of bits in geometry reconstruction. In this paper, we propose a new RDO scheme which takes 3D-Distortion into account instead of traditional video distortion for padded pixels and unoccupied pixels. Firstly, these pixels are classified based on the occupancy map. Secondly, different strategies are applied to these pixels to calculate their 3D-Distortions. Finally, the obtained 3D-Distortions replace the sum square error(SSE) during the full RDO process in intra prediction and inter prediction. The proposed method is applied to geometry frames. Experimental results show that the proposed algorithm achieves an average of 31.41% and 6.14% bitrate saving for D1 metric in Random Access setting and All Intra setting on geometry videos compared with V-PCC anchor.
