This study proposes the metaverse content production pipeline using ZEPETO World, one of the representative metaverse platforms in Korea. Based on the Unity 3D engine, the ZEPETO world is configured using the ZEPETO template, and the core functions of the metaverse content that enable multi-user participation such as logic, interaction, and property control are implemented through the ZEPETO script. This study utilizes the basic functions such as properties, events, and components of the ZEPETO script as well as the ZEPETO player which includes avatar loading, character movement, and camera control functions. In addition, based on ZEPETO's properties such as World Multiplayer and Client Starter, it summarizes the core synchronization process required for multiplay metaverse content production, such as object transformation, dynamic object creation, property addition, and real-time property control. Based on this, we check the proposed production pipeline by directly producing multiplay metaverse content using ZEPETO World.

In this paper, the weak point of AOS jenre online game which occupies the majority of Korea game market of 2014 year is analyzed and to solve the problem, the enhanced design and implementation content is introduced. The proposed game is based on the custom AOS jenre format but has the TPS view and nontargeting format to enhance the action feel. To enhance the game quality, graphics, animation, effect and sound resources are organized. Game server is implemented by multithread of IOCP model to support many clients. The technical issue and design method of client and server are described.

The SMIL specification that is recently approved by the W3C and is meant to help deliver multimedia content to the Web, is widely used in these days and they have continuously emerged tools or softwares related with that. In this paper, I propose an algorithm to convert temporal scripts of RASP that is an experimental toolkit for computer animation that promotes interaction-based programming over time into a SMIL document. For making better use of SMIL documents, we can improve reusability of animation components. And, main contribution of this paper is that it verifies the sequence diagram generated for synchronization of documents by reconverting SMIL from UML sequence diagram.

There have been increasing interests in 3D mobile content service with emergence of a terminal equipping with a mobile 3D engine and growth of mobile content market. Mobile 3D Avatar is the most effective product displaying the character of a personalized mobile device user. However, previous studies on the method of expressing 3D Avatar have been mainly focused on natural and realistic expressions according to the change in facial expressions and lip shape of a character in PC based virtual environments. In this paper, we propose a method of synchronizing the lip shape with voice by applying a SMS message received in mobile environments to 3D mobile Avatar. The proposed method enables to realize a natural and effective SMS message reading service of mobile Avatar by disassembling a received message sentence into units of a syllable and then synchronizing the lip shape of 3D Avatar with the corresponding voice.

This research is to develop the Web-Based Ventilator Management Education Program that reflects the needs of nursing site nursing which is intended to help nursing duties. ISD model-building process has been developed for the analysis, design, development, operation, and evaluation of methods. The education program was developed from April to July 2011, and SPSS 18.0 was used for data analysis. The analysis stage, document review and requirement analysis, content analysis, learner analysis, technology and environment analysis have been executed. Through the processes, higher education requirements for the practical ventilator, a large number of subjects under the age of 30, and the career of less than 3 years of ICU were searched. At the design stage, the education content that was presented by the content expert group was executed in information design, mutual interaction design, synchronization design through discussion with program experts. At the development stage, author made the story flow and gathered data and integrated it through the review of related document and data. At the operation and evaluation stage, author executed the developed program and revised and supplemented it on the basis of the evaluation results through the experts and subjects evaluation. The Web-Based Ventilator Management Education Program could contribute to the improvement of nursing because the program has been developed to reflect the diverse needs of nursing practice in the process of building program.

Multimedia title needs player that depends upon operate system. This raises problems of data compatibility and resource consumption by overlapping development of player. To solve problems, we propose a method which produce multimedia title contents to internet document and then display on internet browser. Contents in multimedia title are transcoded to internet pages, having greate quality, based on CSS Layer for spatial synchronization of multimedia data. This method converts existing DB into XML for multimedia title including personal information. Therefore, XML data and resource information is playable by private multimedia player. Consequently, user can display multimedia content without player using internet browser in anytime.

MPEG-4 is a standard for multimedia applications and provides a set of technologies to satisfy the needs of authors, service providers and end users alike. In this paper, we suggest a Real-time Multiple Circular Buffer (M4RM Buffer) model, which is suitable for streaming these MPEG-4 contents efficiently. M4RM buffer generates each structure of the buffer, which matches well with each object composing an MPEG-4 content, according to the transferred information, and manipulates multiple read/write operations only by its reference. It divides the decoder buffer and the composition buffer, which are described in the standard, by the unit of frame allocated to minimize the range of access. This buffer unit of a frame is allocated according to the object description. Also, it processes the objects synchronization within the buffer and provides APIs for an efficient buffer management to process the real-time user events. Based on the performance evaluation, we show that M4RM buffer model decreases the waiting time in a buffer frame, and so allows the real-time streaming of an MPEG-4 content using the smaller size of the memory block than IM1-2D and Window Media Player.
