An actual fire test was performed on single combustibles placed in a local cinema complex, and quantitative differences in the maximum heat release rate (HRR) and fire growth rate were investigated based on the design fire curve methods (i.e., the general and 2-stage methods). In terms of combustible use and fire load, a total of 12 combustibles were selected, classified into cinema lounge and movie theater. It was found that the maximum HRR and fire growth rate determined using the two-stage method were quantitatively different from those of the general method. The application of the two-stage method, which can be used to determine the fire growth rate of the initial fire stage more precisely, could be useful in accurately predicting the activation time of fire detectors and fire-extinguishing facilities, as well as the available safe egress time (ASET) and required safe egress time (RSET).

This study conducted empirical analysis through user experience and questionnaire to find out whether the technical and contextual elements of the 'COVID-19 SABER' VR game produced and developed through initial research affect the improvement of the user's visual immersion. As a result first, the hypotheses regarding the resolution, viewing angle, effect, and design quality of the technical elements were accepted, but the hypotheses regarding the frame rate and the brightness of the lighting were rejected. Next, as for the hypothesis of the contextual elements, the hypothesis about background, directing, color and texture, interest and fun was adopted, and the hypothesis about storytelling was rejected. In summary, it was concluded that in order to increase the visual immersion of VR games, technical elements resolution, viewing angle, effect, design quality, contextual elements background, directing, color and texture, interest and fun must be designed and produced. The results of this study are expected to serve as basic data for the production and development of VR games that can induce and improve user's visual immersion in the future.

A mobile phone became the practical necessities of Chinese life that can not be explained without a mobile phone as it is rapidly popularized in China in recent years. As income increases due to economic growth, so did desire to buy better products. And This desire has made consumers in China more concerned about design and consequently leads to artistic design of a mobile phone. And also this trend is getting linked to people's personalisation in that people prefer rather to choose products they like than standardized ones in the middle of a variety of cultural inflows. This study mainly focuses on the development of the characterized mobile phone with a high class brand by use of traditional elements and of design identity of a mobile phone with Chines style that is well harmonized with cultural and personalized identity as consumers' preferences are quite different from each other depending on each country's culture. For this, this study investigates traditional elements such as patterns, colors and characters as well as development and features of the mobile phone design. This will also lead to the development of a mobile phone with traditional elements of China by studying utilization of design with traditional patterns. To do this, the study analyzes to research traditional patterns(Dragon, Phoenix, Peony, Lotus Flower), colors(Red, Yellow, Blue, Black, White) and historical origin and concept of characters. The study also looks into instances and personalisation of mobile phone design by analyzing literatures.

Recently, many musical instrument mobile apps have been released targeting normal people who can't play musical instrument at all. The reason of developing video system based on step sequencer are as follows; first, users can freely play the musical instruments; second, induce multiple users to play; and third, develop and suggest new step sequencer fused with the video. To resolve issue in video synchronization caused by sync issues when operating multiple step sequencers, the Pocket Operator of Teenage Engineering was used to realize multiply-connected step sequencer and also, the ultimate video system was developed through Mira-Web for multiple participation. In addition, it's required to make the Pocket Operator as software and receive various feedbacks to continue and complement study in order to develop the better video system.

First of all, What was the modeling technique used to model 3D-Game character? It's a technique developed along several years, by experience... here is the bases Low polygons characters I always work in low polygon for two reasons -You can easily modify a low-poly character, change shapes, make morph for facial expressions etc -You can easily animate a low-poly character When the modeling is finished, Second, In these days, Computer hardware technologies have been bring about that expansion of various 3D digital motion pictured information and development. 3D digital techniques can be used to be diversity in Animation, Virtual-Reality, Movie, Advertisement, Game and so on. Besides, as computing power has been better and higher, the development of 3D Animations and Character are required gradually. In order to satisfy the requirement, Research about how to make 3D Game modeling that represents Character's emotions, sensibilities, is beginning to set its appearance. 3D characters in 3D Games are the core for the communications of emotion and the informations through their facial expression and characteristic motions, Sounds to Users. All concerning about 3D motion and facial expression are getting higher with extension of frequency in use. Therefore, in this study we suggest the effective method of modeling for 3D character and which are based on 2D Graphics.

The study is a user experience design study on the function of action cams used for leisure activities that have been on the rise recently. Along with the video platforms that are developing in a user-friendly way, the size of the action cam market is also growing. However, there is a lack of research on the quality of a function that enhances the user experience. Thus, this study classified action cam functions according to user experience elements by using Kano Model's analysis method and in-depth interview, and analyzed how the quality of action cam functions affects the user experience by conducting a satisfaction survey by function. The results of the study have shown which functions should be improved first and which functions should be continuously researched and invested. I hope this study will contribute useful information to developing user-centered action cams.

Using content analysis, this study explored design differences between Korean and the U.S. corporate characters. Top 100 corporate logs are collected from Korea and the United States. The results showed that Korean characters appear a group of or friends than the ones of the U.S. This result stems from the collective nature of Korea. Korea used more motif of things than the U.S., and Korean personalized characters more often that those of the U.S. Uses of human and animals did not showed statistical differences. In addition, it is found that Korea used blue as main color, and the U.S. used red as main color more often. The number of colors used in character design is not statistically different. These findings could provide academic implications that cultural differences could be adapted to corporate character marketing, and also provide managerial implications.

This study attempts to examine the recent trend of 'Maison & Objet' exhibition which shows everything that forms a space, and seek cases where such 'green amenity' is applied. In terms of morphology, a minimal space was filled with a curved shape, and gradually a design that reproduces nature was produced. As the maximalism gradually emerged, decorative elements were added to the design, and a lot of craft products appeared. In terms of materials, the emotion of naturalism was the most common, and natural wood materials were mainly used. These materials combine with various heterogeneous materials to complete a new design, and natural elements were shaped in space. In terms of colors, the theme in 2016 was 'Wild', and it was possible to see a space where wild nature can be experienced. It showed various colors of nature centered on brown and green of trees. 'Silence' in 2017 is distinguished and characterized by its pink color. Also, pieces of warm reddish brown furniture were made. In the past, brass or rose gold would be trendy, but in 2017, gold or silver colors showed a greater popularity. In 2018, 'Show Room' was the theme, and the representative color was green, which affected new designs with yellow and pink.
