Purpose: This study was designed to systematically explore and elicit information about terminally ill cancer patients' and primary family caregivers' subjectivity of death. Method: Using Q-methodology, 21 terminally ill cancer patients and 19 primary family caregivers sorted 40 statements during personal interviews. Results: The results of this study show that terminally ill cancer patients have four factors ('Attachment to life', 'Hope for heaven', 'Resignation to reality', 'Avoidance of pain') of response and primary caregivers have four factors('Dependence on religion', 'Faithfulness to reality', 'Obedience to fate', 'Agony of reality'). Comparing the subjectivities of death of terminally ill cancer patients and primary family caregivers, 'Hope for heaven' and 'Dependence on religion' reveal the similarities of their outlook. On the other hand, 'Attachment to life', 'Resignation to reality', 'Avoidance of pain', 'Faithfulness to reality', 'Obedience to fate', 'Agony of reality' reveals different aspects of their outlook. The group of terminally ill cancer patients and their families divided into four types. Type A was 'Attachment to life and Agony of reality', type B was 'Attachment to life and Obedience to fate', type C was 'Hope for heaven and Dependence on religion' and type D was 'Resignation to reality and Faithfulness to reality'. The positive group was C or 'Hope for heaven and Dependence on religion'. Conclusion: There are significant differences found in the subjective structure of death among terminally ill cancer patients and primary family caregivers. Therefore, it is necessary to develop an individualized nursing intervention for terminally ill cancer patients and family caregivers.

In recent, mobile augmented reality game which has been attracting high attention is considered to be an good approach to increase immersion. In conventional augmented reality-based games that recognize target objects using a mobile camera and show the matching game characters, touch-based interaction is mainly used. In this paper, we propose an intuitive interaction method which manipulates a deformable game object by moving a target image of augmented reality in order to enhacne the immersion of the game. In the proposed method, the deformable object is intuitively manipulated by calculating the distance and direction between the target images and by adjusting the external force applied to the deformable object using them. In this paper, we focus on the cloth deformable object which is widely used for natural object animation in game contents and implement natural cloth simulation interacting with game objects represented by wind and rigid objects. In the experiments, we compare the previous commercial cloth model with the proposed method and show the proposed method can represent cloth animation more realistically.

This study aimed to output augmented reality display using chroma-key so that power tiller simulator can be operated smoothly while wearing the head mounted display. In this paper, we propose a chroma-eliminating image filtering method. Experimental results show that the maximum and minimum values of hue, saturation and intensity were 0.52, 0.153, 0.57, 0.16, 1, and 0.12, respectively. A keypad was used to set the initial position of augmented reality adjusted with the front, back, top, bottom, left, and right buttons. The initial position value is always maintained and managed according to the trailer attachment and detachment. Finally, we show that the augmented reality merged with virtual image and the acquired image of operation device using coordinate values obtained from the HMD and the position tracking sensor as relative coordinates in Unity program that is the ultimate game development platform.

Augmented reality makes people feel realistic and reduces the damage to cultural properties that can come into contact with the actual cultural heritage. Augmented reality has the advantage that it can show the past appearance of the historical building or relics, the environment, or related information in addition to the current real environment. Despite these values ​and advantages, As a result of researches and analyzes of the Augmented Reality contents of the National Museum, 'palace in my hand', and the Miruksa project In the field of domestic cultural heritage warriors, augmented reality technology has shown a very negative attitude such as simply showing cultural heritage content or using it as a guide. However, various conditions such as display and sensor hardware and technology needed to realize augmented reality more effectively are improving day by day. And If you have various facilities such as the idea of ​adding storytelling to the exhibits and WiFi building, In the near future, it will be equipped with a display system of cultural heritage contents that combines augmented reality with a more complete one.

Recently as AR(Augmented Reality) is focus of attention, AR is applied to various fields and is expected its valuable use. In this paper, we suggested the method to combine existing e_Book with augmented reality technology based on mobile equipment. We ascertained that augmented reality contents implemented on PC work well in pITX embedded lines (CPU Intel ATOM Z530) and we implemented augmented reality using marker in e_ Book in pITX embedded lines through these experiments. As the result of it, we could show the contents at the same time which had difficulty to be expressed on e_Book before. Also the existing augmented reality contents could be used as it is. Finally we expected that the user could interact with virtual contents or services directly and intuitively in the real world.

Training is one of the representative application fields of virtual reality technology where users can have virtual experience in a training task and working environment. Widely used in the medical and military fields, virtual-reality-based training systems are also useful in industrial fields, such as the aerospace industry, since they show superiority over real training environments in terms of accessibility, safety, and cost. The shipbuilding industry is known as a labor-intensive industry that demands a lot of skilled workers. In particular, painting jobs in the shipbuilding industry require a continuous supplement of human resources since many workers leave due to the poor working environment. In this paper, the authors present a virtual-reality-based training system for spray painting tasks in the shipbuilding industry. The design issues and implementation details of the training system are described, and also its advantages and shortcomings are discussed based on use cases in actual work fields.

The nature of animation is to create a moving image. Also, it creates a narrative space and visual image which is different form a reality. Therefore, image expression is very important in the animation. Although the domestic animation has a movement, it has not an image which has meaning. For instance, Korean fiction animation ${\ulcorner}$My beautiful girl, Mary${\lrcorner}$ has grand prize in Anncy International Animated Film Festival, 2002. Such achievement give new vision and present a clue of development to our national animation. However, not many people went to the cinema to watch it. The reason is that although 'Mary' has the Fantastic image, she doesn't show a true life image. The film is revival of reality through the image. However, animation is revival of reality through the 'transformation' of the existing image. Therefore, reviving exactly the same as a reality is not the most important fact in the animation image. Preferably, the most important fact in the animation image is that reviving reality into highly wrought image. This paper will study an expression form of animation trough the image. This paper will study an expression form of animation trough the image. Especially, it will concentrate on poetic image. For this, It will associate 'poetic' in literature with 'poetic image' in animation. For this, It will associate 'poetic' in literature with 'poetic image' in animation. Also, a variety poetic animation image will be divided into 1)mongtage 2)rhythm 3) compression 4)metaphor & symbol, and will be looked 'poetic image' effect.

While pursuing digitalization and paperless projects, the construction industry needs to settle on how to make the most of digitized data and information. On-site workers, who currently rely on paper documents to check and review design and construction plans, will need alternative ways to efficiently access the information without using any paper. Augmented Reality is a potential solution where the information customized to a user is aligned with the physical world. This paper proposes the Augmented Reality framework to deliver the information on on-site resources (e.g., workers and equipment) using head-mounted devices. The proposed framework was developed by interoperating Augmented Reality-supported devices and a digital twin platform in which all information related to ongoing tasks is accumulated in real-time. On-site resources appearing in the user's field of view are automatically detected by an object detection algorithm and then assigned to the corresponding information by matching the data in the digital twin platform. Preliminary experiments show the feasibility of the proposed framework. Worker detection results can be visualized on HoloLens 2 in near real-time, and the matching process obtained the accuracy greater than 88%.

Mixed-reality technologies have proven to be valuable in many architecture, engineering and construction / facilities management (AEC/FM) applications. However, its potential of being adapted to facilitate hazard identification and risk communication in construction workplaces has yet to be fully explored. This paper makes an attempt to evaluate the feasibility of applying mixed-reality to enhancing safety risk communication in construction workplaces. Experiments have been designed in which Microsoft HoloLens^® together with a developed application will be used to intervene in the practice of jobsite risk communication. A cross-sectional survey will then be followed to examine the effectiveness and acceptability of this technology through analysis on data collected from participants in the construction industry. The preliminary results show that this emerging HoloLens^® technology, compared to the traditional communication methods (i.e., phone calls, walking up people and talk, and video conferencing), facilitates accurate, prompt safety communication on construction sites. Such findings signify the potential of applying mixed-reality to safety performance enhancement in the construction industry.
