A public library is changing into a place where people can freely acquire and make use of information in digital environment with the basic ideology of publicity. In spite of such changes, multimedia center is still biased with the function of computer room to use PC and is not used actively by many users. This study can be summarized and concluded as follows and spatial characteristics of digital data room of public library can make use of space planning elements by aspects as an analysis tool. First, designed characteristics focusing too much on the possession of seats for reading digital data. Therefore, spatial planning for users to choose necessary facilities according to the data they wish to read and type of users is needed. Second, interior tone of multimedia center is applied with identical color for all floors, walls, and ceilings, to create sense of unification. However, due to the arrangement of similar colors, while using identical brightness and chroma, some users felt difficult to realize shape or depth in space. It is more appropriate to apply distinctive color plan according to the characteristic of the data or space region, in order to create pleasant digital environment for visually weaker people or elderly. Third, psychological or technical factors of multimedia center is not sufficiently applied in space planning elements for users. In order for various digital service of public library to be technically implemented, it is necessary to organize open space by expanding the size of multimedia center to utilize high-tech facilities.

Packet losses in the Internet can dramatically degrade quality of multimedia streams. Forward Error Correction (FEC) is one of the best methods that can protect data from packet erasures by means of sending additional redundant information. Proposed control algorithm provides the possibility of receiving real-time multimedia streams of given quality wifth minimal traffic overhead. The traffic optimization is reached by adjusting packet size as well as block code parameters. Calculations and simulation results show that for non-bursty network conditions traffic optimization can lead to more than 50% bandwidth reduction.

The recent broadcasting environment has shifted to embrace multimedia and multi-channel features through terrestrial, satellite and cable media. This has multiplied the number of broadcasting programs. With the information on a myriad of programs provided to TV viewers, information overload occurs, and thus, the TV viewing environment is shifting to one where viewers cannot select programs passively. Thus, a growing need is emerging to ensure a personalized electronic program guide (EPG) to help individuals select TV programs according to their taste. This paper presents a personalized EPG that enables a purpose-oriented broadcasting service to provide personalized broadcasting programs in tune with the user's requirements and preferences.

As contemporary men's clothing is becoming slimmer, people consider it important not only the existing simple design, but also intricate design and its fitness that can complement one's body. Therefore, in this study, we reproduced Men's wear fabrication process with 3D process. As a result, it was well received, as it can check the fitness, and allows modifying the design and mixing different texture easily.

현재까지의 음성 출력 시스템은 텍스트를 있는 그대로 읽어 주는 것에 불과했다. 단위, 약어의 경우 알파벳을 그대로 읽어 주게 되어 그 본래의 의미를 제대로 파악하기 어려웠다. 본 연구에서는 단위나 약어의 본래의 의미를 찾아서 풀어서 음성 변환해 주는 방법을 제안함으로써 시각 장애인에게도 텍스트의 정확한 정보를 전달할 수 있다는 장점이 있다.

A literature analysis for the planning and realization of the multimedia meta database and digital library's integrated information system was carried out to establish the various oceanographic resources in the Oceanographic Information Center, the first in Korea. The study targeted from printed matter, network resources, full-text and to VOD. The focus of the analysis lies in the providing practical integrated information retrieval service for oceanographic resources based on the framework of effective MODS metadata with network resources description. The analyses included oceanographic resources, multimedia information processing, MODS metadata descriptive elements, metadata classification, system organization, and retrieval for planning and implementation of the multimedia meta database system.

The manufacturing industry is continuously pursuing advanced technology and smartization as it converges with innovative technology. Improvement of manufacturing productivity is achieved by monitoring, analyzing, and controlling the facilities and processes of the manufacturing site in real time through a network. In this paper, we proposed a new OPC-UA based digital twin model for smart factory facilities. A testbed system for USB flash drive packaging facility was implemented based on the proposed digital twin model and OPC-UA data communication scheme. Through OPC-UA based digital twin model, equipment and process status information is transmitted and received from PLC to monitoring and control 3D digital models and physical models in real time. The usefulness of the developed digital twin testbed system was evaluated through usability test.

Due to the rapid development of Information and communication, the technology of multimedia presentation technology is evolving into the service that user can actively, realistically enjoy and play based on user's preference and taste not only for User's passive service. Especially, the industry related the realistic multimedia service that supports targeting Human emotion with the property of Human hearing is expected to be formed of the high value-added premium market. Audio technology is affected on human's emotion and the viewing environment around than video technology. Also the audio technology compared to video technology is a research part that appeals to human emotion and emphasize on psychological aspects. With this viewpoint, the development of intelligent and realistic audio technology needs highly specialty. In this study, "intelligent real-sound presentation technology" that support high quality and realistic audio and the "core technologies" that are composing of this will be introduced.
