Developments and changes in digital environment based on computer technologies and internet networks enabled us interactive communication for planning and execution through the freedom of 'connection', 'sharing', and 'conversion'. The subject of this study, interactive commercial, might be the core of success based on creation which stems from communication design, revolution in design and technology, and conversion. Communication in modern economy is not optional, but essential. Furthermore, like evolution process up to Augmented Reality from developments of mobile communication technology, or concept in paradigm change, digital interactive commercial means the core of success, not a part of it. Therefore, in order to achieve success in the global competition structure, mobile communication design, revolution, and creation which produce added value shall be working as a base. In order to reach effective communication process performance of interactive commercial media, this study would like to propose building a media commercial system which is realized by human senses. Using this, standardized methods for interactive commercial which can be used together with augmented reality based on digital technology, and for using digital robot contents are available, along with methodology system of their use. In addition, the ultimate goal of this study aims to discover new factors through reorganization of precedent analysis and adaptation based on academic achievement and practical application. And thus, it wants to contribute to practical use of interactive commercial out of augmented reality-based communication in which technology, marketing, and design are integrated to be used in real sense.

본 연구는 가상현설 콘텐츠의 경제, 산업적 영향이나 파급효과 보다는 콘텐츠로서 가상현실 콘텐츠의 스토리텔링 방법이 기존 콘텐츠의 스토리텔링 방식과 어떠한 차이가 있는지, 어떠한 구별되는 특성을 가져야 하는지를 탐구한다. 웹툰 콘텐츠를 가상현실 콘텐츠로 전환할 경우, 기존의 웹툰 스토리텔링 방식이 가상현실 콘텐츠에서 어떻게 적용될 수 있는지를 고찰하고, 이를 통해 가상현설 콘텐츠 스토리텔링 기법의 한계와 가능성을 도출하는 것이 본 연구의 목적이다. 본 연구를 통해 가상현실 콘텐츠 스토리텔링의 핵심은 가상현실을 체험하는 대상이 기술과 서비스를 사용하는 사용자, 콘텐츠의 관람자로서의 관객, 스토리를 진행시키는 연출자 세 가지 역할을 동시에 수행하는 것에 있음을 알 수 있었다. 이는 영상콘텐츠 스토리텔링 기법에서 가장 중요한 연출자의 의도를 반영하는 편집 및 카메라 시점 변경 등의 방식이 가상현실 콘텐츠에서는 더 이상 강제요소가 될 수 없기 때문이다. 가상현실 콘텐츠의 스토리텔링 기법은 사용자의 상호작용, 감각의 확대, 시선 자유 보장에 있어서 기존 콘텐츠에 비해 제한적일 수밖에 없다.

Hijab as a symbol of women's oppression due to the opening and reform of Islamic State group, is becoming more diverse as younger generation begins to dress more freely than ever before, spreading the perception that it is a fashion item. In response, this research conducted a theoretical review about the history of hijab, various forms of hijab, and characteristics of hijab using relevant literature, media reports, and fashion media articles. As an empirical study, image-oriented photo data shared by Tehran Street Fashion from 2015 to November 2019 were analyzed separately by fashion majors into color, pattern, and hijab-making forms. According to the analysis, six different fashion images were categorized as romantic feminine, modern chic, natural elegant, classic formal, sporty casual and gorgeous ethnic. For Muslim women in the past, hijab was worn as a repressive and closed sense by the religious system. However, in modern times, it is a way to express one's style and ideas as a fashion item. It is also and a means to express one's thoughts and beliefs. Through aesthetic consideration of Hijab as a fashion item, it was found that it was a medium for freedom of expression and a medium for beauty and individuality.

The objective of this study was to evaluate the characteristics of the fashion narrative from the commercial and artistic viewpoints by identifying and evaluating the attributes of the fashion narrative and analyzing the fashion narrative focusing on various cases according to fashion media. Louis Vuitton, a brand of the Louis Vuitton $Mo{\ddot{e}}t$ Hennessy (LVMH) group that operates the entire fashion community platform, is recognized as an influential luxury company with enormous capital and capabilities. This study targeted Louis Vuitton to examine the fashion narrative. The common results of Louis Vuitton's fashion narrative according to the communication platform are as follows. First, it emphasizes well-designed craftsmanship and artistry to convey the value and meaning of the brand. Second, it expresses the lifestyle of the bourgeoisie using traveling for finding life purpose, nature, and freedom as common denominators. Louis Vuitton connects, shares, and engages with customers by crossing the communication platform and trying multi-sensory changes based on the fashion narrative of the 'artification' message encompassing craftsmanship, innovation, and travel. The fashion narrative of Louis Vuitton applies tools (e.g., design, direction, stage, and props) differently according to the nature of media. In other words, the fashion narrative in the form of transmedia storytelling is a marketing communication strategy that indicates the representation means and direction of a brand's goals by remediating the brand narrative in various ways through the communication platform.

Having gone through socioeconomic changes from an agricultural to a post-industrial society, mental health system accordingly has been changed. In Korea where the socioeconomic change has been so rapid, the mental health system and law have been behind the socioeconomic system. Post-industrial society needs more humanized and advanced mental health system, however, Korean mental health law reflects ideology of Korean society in industrial age. This paper attempts to assess the significance Korea's Mental Health Law against the backdrop of socioeconomic changes. A substantial part of the report is devoted to identifying discrepancies between Korea's Mental Health Law and the perspectives of post-industrial ideology and areas for improvement. Improvement in mental health law should take place in line with the changes occurring in socioeconomic environments, the social concept of family, and the public awareness of human rights. Korea's mental health law should be changed in a way to improve hospitalization procedure for people with mental illness, promote the opening of mental health facilities and improve the quality of the lives of the mentally ill. Further changes are deemed necessary in the public and media view of mental illness. Also, the national budget will have to be increased with a view to raise the social rights of those with mental illness to receive quality rehabilitation services.

The demand for virtual reality (VR) is rapidly increasing. Providing the immersive experience requires much operation and many data to transmit. For example, a 360-degree video (360 video) with at least 4K resolution is needed to offer an immersive experience to users. Moreover, the MPEG-I group defined three degrees of freedom plus (3DoF+), and it requires the transmission of multiview 360 videos simultaneoulsy. This could be a burden for the VR streaming system. Accordingly, in this work, a bitrate-saving method using projection conversion is introduced, along with experimental results for streaming 3DoF+ 360 video. The results show that projection conversion of 360 video with 360lib shows a Bjontegaard delta bitrate gain of as much as 11.4%.

Development of technology in the $20^{th}$ century has made great contributions to women's lives. With the development of digital convergence, home network, and DMBs (Distance Method Bracings), the ubiquitous technology information era is expected to create a new progressive era for women. The purpose of this study is to investigate the lifestyle that Korean women would like to pursue, especially in regards to the sense of value within the personal and social life of each individual. As a method to suggest how the socio-cultural trends of women's lifestyle will change in the ubiquitous era, qualitative interviews have been conducted over 6 groups with 77 persons between the digital ages of 20s and 30s, living in Seoul. The majority had positive opinions regarding the economic, cultural, emotional, and physical prospects of the ubiquitous information environment. Results show high expectations evolved around freedom from household chores, the equality between the sexes (at home and in society), enhancing the working environment at home, an expansion of human relationships leading to creative knowledge, being able to maintain a single life without economic constraints, and the enjoyment that the internet provides. for suggestions to improve the quality of women's lifestyle through ubiquitous technology, issues such as individual based customization, time management, creating emotional hyperspaces, multi-media communication systems, and women as leaders were studied.

The bobsleigh is a winter sport which use a sled to slide down an ice-covered course. There is a big expectation for having a training environment and being able to train year round. At present, training is very limited due to the season or course facilities. A variety of VR (Virtual Reality) equipment has been developed in recent years, and it is beginning to spread. We have also made our contribution in bobsleigh simulation. The reactive force applied in our bobsleigh simulation is much smaller than that of a real bobsleigh. This paper proposes a method to enhance reactive force of bobsleigh simulation in real time. The reactive force is magnified instantly in the physically-based simulation. The Laplacian filter is applied to the sequence of reactive force, this technique is often used in the field of image processing. The simulation is comprised of four large scale surround screens and a 6-D.O.F. (Degree Of Freedom) motion system. We also conducted an experiment with several motion patterns to evaluate the effectiveness of enhancement. The experimental results proved useful in some cases.
