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.

최근 높은 관심을 모으고 있는 모바일 증강현실 게임은 몰입감을 높이기 위한 접근 방법으로 손꼽히고 있다. 모바일 디바이스의 카메라를 이용하여 대상 물체를 인식하고 게임 캐릭터가 등장하도록 하는 기존 증강현실 기반의 게임에서는 대부분이 터치 기반의 인터랙션만을 사용하고 있다. 본 논문에서는 게임의 몰입도를 높이기 위하여 증강현실 타겟 이미지를 움직임으로써 게임 속 변형 객체를 직관적으로 조작하는 기법을 제안한다. 제안 방법에서는 타겟 이미지들 사이의 거리와 방향을 계산하고, 이에 따라 변형객체에 주어지는 외부력(external force)의 크기를 조정함으로써, 직관적 방법으로 변형 객체의 움직임을 조작할 수 있도록 하였다. 본 논문에서는 게임 콘텐츠에서 자연스러운 객체 표현을 위하여 많이 사용되고 있는 변형 직물(cloth) 모델에 초점을 맞추었고, 바람(wind)과 강체(rigid object)로 표현되는 게임 객체들과 상호작용하는 자연스러운 직물의 움직임을 표현하였다. 실험에서는 유니티 에셋 스토어에서 판매하는 기존 유료 직물 모델의 적용 결과와의 비교를 통하여 제안 기법이 보다 현실감 있는 직물의 움직임을 표현하고 있는 것을 보였다.

증강현실은 역사적 건조물이나 유물의 과거 시점의 모습, 환경, 혹은 관련 정보를 현재 실제 환경에 더하여 보여줄 수 있다는 장점이 있다. 문화유산 전시부분에서 증강현실 기술의 도입은 관람객에게 현실과 같은 현전감을 제공하고, 문화유산과 실제로 접촉하면서 생길 수 있는 훼손 요소를 줄여준다는 점에서 더욱 활발하게 요구되고 있다. 이러한 장점과 가치를 가지고 있음에도 불구하고 현재 국내에 가상현실 기반 문화유산콘텐츠 전시환경은 문화유산 콘텐츠를 단순히 증강해서 보여주거나 가이드 정도로 사용하는 등 매우 소극적인 행보를 보이고 있다. 국외의 다양한 성공적인 사례를 분석한 결과 완성도 높은 증강현실을 결합한 문화유산콘텐츠의 전시 시스템을 갖추기 위해서는 문화재에 스토리텔링을 더하는 아이디어와 함께 디스플레이, 센서 등의 기술 여건 개선, 와이파이 구축 등의 제반 시설이 동반되어야 할 것이다. 본 연구는 국내의 증강현실 기반의 문화유산콘텐츠 개발 역사가 짧고, 전시사례가 부족하다는 점에서 한계점을 가지나 추후 후속 연구를 통해 우리의 훌륭한 문화유산에 증강현실이 결합된 문화유산콘텐츠 전시사례들이 많이 나오기를 기대한다.

최근 증강현실(Augmented Reality)에 대한 관심이 증대되고, 이와 관련된 기술들이 발전함에 따라서 증강현실이 다양한 분야에 적용하려는 시도가 늘어나고 이에 대한 활용에도 기대가 모아지고 있다. 본 논문에서는 기존의 전자책과 모바일 기기 기반 증강현실 기술을 접목할 수 있는 방안을 제안하였다. PC 상에서 구현된 증강현실 콘텐츠가 pITX 임베디드 계열(CPU Intel ATOM Z530)에서 대부분 잘 동작함을 실험을 통해서 확인하였으며, 이를 바탕으로 전자책 속의 마커를 이용한 증강현실을 pITX 임베디드 계열에서 구현하였다. 그 결과 전자책에서 표현하기 어려운 콘텐츠를 동시에 제시할 수 있으며, 기존의 증강현실 콘텐츠를 그대로 이용할 수 있으므로 사용자가 현실 세계에서 가상의 콘텐츠 또는 서비스와 직접적이고 직관적인 상호작용을 손쉽게 할 수 있을 것으로 기대된다.

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.
