The facade design of apartment is getting more important, since residents'needs on raising the quality of housing have increased, and also public interests on urban landscape are higher than before. As a way of improving facade design the necessity of remodeling consequently has been risen. The government also relieves the regulations related to remodeling. A apartment facade design should address how to express both identities and aesthetic tastes of residents, so they want to reflect their own ideas and opinions on the apartment facade design during the remodeling process. It is not always easy, unfortunately, to reflect residents'ideas and opinions due to the public characteristics of apartment facades and absence of tools that support effective design participation. This paper proposes an internet-based collaborative design process that supports residents'active participation in the exterior remodeling process of apartment. We outline three main issues involved in developing the design system: 1) a semantic facade database built upon classification of building facades; 2) an Internet-based facade modeler based on a real-time, rule-based procedural modeling method; and finally 3) the virtual reality(VR) simulation that allows a group of designers and residents to design in a collaborative fashion.

The virtual engineering technologies have been broadly used for the design, testing, manufacturing and maintenance works of industrial product. Recently many VR systems with walk through navigation and web databases; such as design and installation database. load history database, maintenance history database et al. are developed. However, the virtual engineering in railroad industry is not well developed compared to other industries like automobile, air, shipbuilding. In this paper, we explain the strategy that we have applied the virtual engineering technology to the design works of rolling stock and our plan to build the virtual testing laboratory(VTL) in the Korea Railroad Research Institute.

It is an interesting area in the field of artifical intelligence to find an analytic model of cooperative structure for multiagent system accomplishing a given task. Usually it is difficult to design controllers for multi-agent systems without a comprehensive knowledge about the system. One of the way to overcome this limitation is to implement an evolutionary approach to design the controllers. This paper introduces the use of a genetic algorithm to discover a fuzzy logic controller with rules that govern emergent agents solving a pursuit problem in a continuous world. Simulation results indicate that, given the complexity of the problem, an evolutionary approach to find the fuzzy logic controller seems to be promising.

In the paper the authors describe the development of ITIS(Intelligent Tunneling Information System) for the Purpose of applying the 3D visualization technique, GIS, AI(Artificial Intelligence) to tunnel design and construction. VR(Virtual Reality) and 3D visualization techniques are applied in order to develope the 3D model of characteristics and structures of ground and rock mass. Database for all the materials related to site investigation and tunnel construction is developed using GIS technique. AI technique such as fuzzy theory and neural network is applied to predict ground settlement, decide tunnel support method and estimate ground and rock mass properties according to tunnel excavation steps. ITIS can help to inform various necessary tunnel information to engineers quickly and manage tunnel using acquired information based on D/B.

Haptic systems have been widely used for both virtual reality and augmented reality application including game, entertainment, education and medical sectors. Clothing designers and retailers initiated using AR and VR technologies to help the consumers find style with the perfect fit. Most of the developed augmented reality shopping is implemented by overlapping the image of the clothes on the customer so that he/she can find the fit. However, those are only visual information and the customer cannot experience the real size and the stiffness of the clothes. In this paper, we present the haptic upper garment which provides the haptic feedback to the user using cables. By controlling the length of the cable, the size of the clothes is set and by stiffness control, the compliance of the fabric is implemented. The haptic garment is modeled for precise control and the distributed controller architecture is described. With the haptic upper garment, the user's experience of the virtual clothes is greatly enhanced.

This study proposes a STEAM (Science, Technology, Engineering, Arts, and Mathematics) program for career exploration of middle school students. The proposed program utilizes VR (Virtual Reality) for new digital technology and webtoon as a popular cultural element. It enables the students to investigate promising fields and experience them virtually for themselves. We design the program based on the 2015 revised curriculum, which enhances the learning effects with existing subjects. In particular, the program provides a hybrid education to combine contact and untact classes considering the COVID-19 situation. The educational goal of the proposed program is to improve creativity and convergence capability. Specifically, it aims to prepare an educational foundation that integrates new digital technologies into education and applies the programs to school education fields. To prove the effectiveness of the developed program, we applied the program to the second graders of A middle school located in Seoul. We expect that the proposed program helps students learn how to utilize new digital technologies and explore future career paths.

The purpose of this study is to investigate the educational needs of virtual reality(VR)-based communication and teamwork skills for patient safety intended for nursing students and nurses. For this study, mixed method design was used with surveyed data collected 60 nursing students and 123 nurses. And fourteen nurses was conducted focus group interview. SPSS/WIN 25.0 and inductive content analysis for focus group interviews were utilized for data analysis. The results indicated that the awareness of VR and educational needs of team communication, and teamwork skills were above average, and nursing students required higher educational needs than nurses. Teamwork knowledge was moderate, and there was no significant difference between the two groups. Regarding nurse's communication in hospital, 4 themes of contributing factors and 2 themes of result factors that cause communication difficulties among nurses were derived from the qualitative data. Therefore, it is necessary to develop a virtual reality-based simulation program reflecting the educational needs of nursing students and nurses in order to improve team communication and teamwork skills for patient safety required for nursing students and nurses.

The purpose of this study is to analyze the characteristics and problems of the content of flower design education videos on YouTube and to search for improvement direction. The subjects of analysis were 129 pieces of videos uploaded in the last one year including 'craftman floral design' as a search term. The result shows that contents covered were practical lectures, theory lectures, test related tips, job and character introduction, test work, educational guidance and publicity. The production format could be divided into studio lecture, classroom lecture, video feature, interview, Vlog, and television program. The hub-type programming strategy that periodically uploads the videos satisfying the target audiences' interests is mostly applied. The type of lecture covered 'practical skill test' got a good response from the users. Overall, content diversity, interaction between creators and users, and harmonious programming strategies are lacking. In order to improve this, it is necessary for emotional and expressive creators to pioneer differentiated fields and practice based on actual field. The introduction of interactive elements such as games and quizzes and the application of new media technologies such as VR and AR are worth trying. Three strategic types of 'hero', 'hub', and 'how to' should be applied complementary. As the demand for education content related to flower design is expected to expand in the future, it is required to develop content that can be used in various platforms, foster professional creators, and develop associated business models.
