Maya Deren is well known as the 'mother' of the American avant-garde films by her first short, Meshes of the Afternoon (1943). One of the major contributions of Maya Deren's theoretical body of work to the visibility was the invention of a new vocabulary for independent film-making such as 'film-poems', and 'choreo-cinema'. To create experimental film forms, she chose poetry, dance, architecture and music as a metaphor to describe her images. On the top of these arts, Maya uses camera works and editing system to achieve an 'artificial reality' whose character is miraculous in that living whole, in order to help the audience to experience a protagonist's psychological journey.

Through the computer simulation of virtual reality techniques, prospective clients can experience the surroundings such as the view, traffic and convenience facilities in advance. Also, consumers can reflect their own tastes in the real apartment Interior construction through their own work in relation to furniture arrangement, color choices, etc. inside the apartments. The virtual model house not only replaces the function of the existing model house but it can also provide some services that could not be provided easily due to some restrictions under real conditions. More, it can provide a precise view of the outside appearance and surrounding environment as well as inside the house, as virtual structures on the computer. Consumers can search for the information through the Web in advance and consumer-satisfaction type of apartments can be built. For this purpose, smooth communications among the designers, server managers, and consumers should be achieved as a prerequisite to the delivery of the necessary information.

The aim of this study was to perform a meta-analysis of the learning outcomes of immersive learning technologies in English language teaching (ELT). This study examined 12 articles, yielding a total of 20 effect sizes. The Comprehensive Meta-Analysis (CMA) program was employed for data analysis. The findings revealed that the overall effect size was 0.84, implying a large effect size. Additionally, the mean effect sizes of the dependent variables revealed a large effect size for both the cognitive and affective domains. Furthermore, the study analyzed the impact of moderator variables such as sample scale, technology type, tool type, work type, program type, duration (sessions), the degree of immersion, instructional technique, and augmented reality (AR) type. Among the moderators, the degree of immersion was found to be statistically significant. In conclusion, the study results suggested that immersive learning technologies had a positive impact on learning in ELT.

Virtual reality is becoming a powerful tool for various applications such as training, entertainment, surgery, tele-robotics etc. One potential use for virtual reality is to allow several users to interact in a single virtual environment, for example several students sitting in front of different computers connected over a network. In this paper, we present a loosely coupled architecture of haptic display in the multi-user virtual world. The method of controlling haptic devices as well as the way of configuring individual haptic display system are addressed. We will develop an experimental virtual reality system for two remote users and conclude with an experimental work for the task of a multi-player ping-pong and grasping of a common object.

This paper describes elemental technologies for the creation of three-dimensional(3-D) sound-field to implement the next-generation Ship Handling Simulator with human -computer interaction, known as Virtual Reality. In the virtual reality system, Head-Related Transfer Functions(HRTF's) are used to generate 3-D sound environmental context. Where, the HRTF's are impulse response characterizing the acoustical transformation in a space. This work is divided into two parts, the part Ⅰis mainly for the model constructions of the HRTF's, the part Ⅱis for the control of 3-D sound-field by using the HRTF's . In this paper, as first part, we search for the theory to formulate models of the HRTF's which reduce the dimensionalityof the formulation without loss of any directional information . Using model HRTF's we report results from psychophysical tests used to asses the validity of the proposed modleing method.

As non-face-to-face activities have become commonplace, online video conferencing platforms have become popular collaboration tools. However, existing video conferencing platforms have a structure in which one side unilaterally exchanges information, potentially increase the fatigue of meeting participants. In this study, we designed a video conferencing platform utilizing virtual reality (VR), a metaverse technology, to enable various interactions. A virtual conferencing space and realistic VR video conferencing content authoring tool support system were designed using Meta's Oculus Quest 2 hardware, the Unity engine, and 3D Max software. With the Photon software development kit, voice recognition was designed to perform automatic text translation with the Watson application programming interface, allowing the online video conferencing participants to communicate smoothly even if using different languages. It is expected that the proposed video conferencing platform will enable conference participants to interact and improve their work efficiency.

This study examines the themes the two authors shared - anti-colonialism, anti-imperialism, anti-imperialism, and anti-ideology - 《The Myth of the 20th Century》 and 《The Age of Passion》, 《Waiting for the Barbarians》 and 《Disgrace》. Both pieces opposed imperialist aggression and oppression and rejected colonial rule with the issue of their identity as strangers, and stood up against huge powers, including the fictionalization of ideology, racism, and despotism. Kim Hak-chul understood communism as a humanitarian, not a personal cult or individual dictatorship. Most of his work is autobiographical novels that he has experienced and are based on realism. Kim Hak-chul voluntarily chose China to actively fight against reality and showed the reality as it is to change history and politics, but Coetzee did not directly reveal the relationship between the perpetrator and victim, the ruler and the one being ruled, but maintained a certain distance from politics, revealing the reality of society and its system.

가상현실 기술의 발전과 해양개발 산업의 급성장으로 해양 산업 분야에서 데이터 분석, 가상 체험, 교육 및 모의 훈련 등의 목적에 활용할 수 있는 가상 해저 시뮬레이션에 대한 연구가 다양하게 진행되고 있다. 가상 해저 시뮬레이션 시스템은 3차원 그래픽 기술을 통한 시각적인 체험을 위주로 개발되고 있어 체험자가 현실감을 경험하기에는 한계가 있다. 가상현실을 이용한 해저 시뮬레이션을 구현하는데 있어서 현실감 향상을 위해서는 모의적으로 생성된 가상환경에서 시청각적인 요소 이외의 감각적인 부분을 통해 사실적인 체험이 가능한 요소가 필요하다. 본 논문에서는 해저환경의 물리적 현상에 따라 다감각 효과를 제공할 수 있는 가상 해저 체험 시뮬레이션 시스템을 개발 하였다. 또한 제안 시스템의 유효성을 검증하기 위하여 참가자 실험을 통하여 현실감에 대하여 평가 하였다.

본 연구는 최근 건설분야에서 활용도가 높아지고 있는 증강현실 도구를 활용하여 학생들이 철근공사 배근작업을 학습할 수 있는 교육지원 컨텐츠를 개발하고 적용효과를 분석하였다. 구조도면에 대한 이해도를 높이기 위해 구조도면을 마커 이미지로 활용하였으며, 구조도면에 따라 배근된 가상의 3D 배근 모델을 화면에 겹쳐 표현하는 방식으로 증강현실을 구현하였다. 또한 3D 배근 모델과 함께 2D도면의 독도법, 이음 정착길이 기준, 부재별 구조설계기준에 따른 배근방법, 그리고 실제 배근하는 순서 등을 학습할 수 있도록 컨텐츠를 구성하였다. 적용결과 인터페이스 스타일, 지각된 유용성, 지각된 활용의 용이성, 지각된 즐거움, 활용 태도, 활용 의도 측면에서 긍정적으로 평가되었으며, 증강현실은 교육적 측면에서 시각화와 상호작용의 장점이 있기 때문에 활용가치가 높을 것으로 판단된다.

This study was undertaken to evaluate the living condition and the reality of visiting part-time workers through the survey. On the matter of living condition, the most difficult problem is financial problem followed by residential problem. On the matter of female's household labor, there was a considerable difference according to the houseband's age and academic background, and family monthly income. On the question of family relationship, it was found that there was rare communication between children and father because father was rigid to talk with. In the case of mother and children, they could not find time to talk with each other. In the group of the old aged, they work to make their living. On the other hand, in the group of younger generations and the higher educated, they replied that they should work whatever the work is. It was found that they were subjected to their work because of their financial situation and that they were under the double yoke of family and work because there were no legal protection and organizational devices.
