As a digital TV has outstanding features of being the most influential device in the living room and having the wide spectrum of users, several internet services has been ported on the digital TV platform (in the form of data services) in order to enhance their brand powers. Most of the services, however, failed to get a satisfactory results as the data services are defeated by the broadcasting contents in the competition for the viewer's interests. In the paper, the design guidelines that make data services not to compete with the broadcasting contents are proposed and a prototype of a data service that accommodates the guidelines is introduced.

By using Monte Carlo simulation method we developed a new molecular simulation software which can be used to predict the thermodynamic properties of organic compounds. Starting from molecular structure and intermolecular potential function, rigorous statistical mechanical principles give a probability distribution for the behavior of a system containing many molecules, which enables us to calculate macroscopic thermodynamic properties of the system. The software developed in this work, cheMC, is based on Windows platform providing with easy access. One can efficiently administrate simulations by using an intuitive interface equipped with visualization tool and chart generation. It is expected that molecular simulations supplement the equation of state approach and will play a more important role in the study of thermodynamic properties.

웹 기술의 발전과 스마트폰 이용자 수의 증가는 소비자와 기업 간의 관계를 혁신적으로 변화시키고 있다. 기업이나 공공기관들은 고객들과 커뮤니케이션 효과를 극대화 하기 위해 새로운 크로스미디어 플랫폼으로 등장한 소셜미디어를 적극적으로 활용하고 있다. 블로그, 페이스북, 인스타그램 등 더욱 다양하지고 변화의 속도가 빨라지는 소셜미디어 트렌드 속에서 기업들은 채널의 특성에 따라 어떠한 콘텐츠가 소비자에게 만족과 구매에 중요한 영향을 미치는지 체계적인 분석과 운영전략이 필요한 실정이다. 본 연구에서는 기업 마케팅의 활용 관점에서 블로그와 SNS 채널 특징에 따라 콘텐츠 유형의 만족도를 비교 분석하고, 이용자의 개인 특성에 따라 채널별로 어떠한 차이가 있는지에 관한 전략적 틀과 시사점을 제시하고자 한다. 이를 위해 소비자와 판매자 간의 커뮤니케이션 방법에 따라 소셜미디어 콘텐츠를 홍보성, 정보성, 소통성 유형으로 구분하여 블로그 페이스북, 인스타그램의 소셜미디어 채널별로 소비자 만족도를 조사하고자 한다. 또한, 인터넷 이용자의 개인 특성에 따라 선호하는 SNS 콘텐츠 유형이 다를 수 있음에 착안하여 SNS를 이용하는 사용자의 특성을 네 가지 형태로 분류하고 특성에 따른 만족도의 영향관계를 분석하였다. 본 연구 결과를 통해 다양한 소셜미디어 채널을 활용하고자 하는 기업들에게 효율적인 SNS 마케팅 전략구축 방안과 인터넷 이용자 특성을 고려한 콘텐츠 활용 방안에 대한 시사점을 제시하였다.

Virtual reality items are increased take-all type of markets like Universal, such as the United States as a leader in the virtual reality technology. Multi-user have to get direct experiences with the whole body like visual, tactile, hearing, sense of movement, and it must be developed new forms of content platform to enjoy immerse deeply into the content. Visitors are not to enjoy the content passively but rather to enjoy the content actively. So it like that should develope content to maximize the immersion. It need the development of new forms of mixed 5D virtual reality Attraction content with all of factors like $360^{\circ}$ circle vision, stereoscopic images, interaction, simulator, and the environmental effect. We proposes how to make the color and brightness calibration technology for this purpose.

Mobile network evolution and development of USN technologies introduce new business model based on context awareness. Cellular operators provide friend finding service using cell based location information and telematics service using GPS location information. Recently cellular operators provide yellow page service based cell based location information. In this paper, we develop mobile tour application on WIPI platform based on location information. Mobile tour information services provide the best information based on context awareness using user location information from LBSP (Location Based Service Platform), season, weather conditions, time from Web server, and personal preference information stored in database. Mobile tour information service application is developed on WIPI platform.

최근 인터넷 이용이 증가하면서 원격 교육자료, 전자상거래용 자료 등 여러 이용자가 사용하는 자료를 하나의 서버가 아니라 분산된 형태로 나누어 관리하는 것이 통신량을 줄이기 위해 점차 중요시되고 있다. 특히 멀티미디어 자료는 데이터 량이 많으므로 이용자에게 가까운 서버에 분산 관리하는 것이 더욱 필요하다. 본 논문에서는 CORBA 표준을 따르는 미들웨어를 사용하여 인터넷으로 상호 연결된 임의의 시스템에 자료를 분산 관리할 수 있는 분산형 자료 관리 시스템 DDM(Distributed Data Manager)을 구축하였다. DDM은 크게 나누어 사용자 관리, 데이터 관리, 시스템 상태 관리 기능을 제공하며 단순히 분산 자료의 위치만을 관리하는 것이 아니라, 자료를 종류별 또는 용도별로 통합된 category를 관리한다. DDM은 분산 자료의 통합관리와 시스템 상태 관리를 위해서 주 에이전트(Primary Agent, 이하 PA)와, 이용자에게 직접 서비스를 제공하는 보조 에이전트(Local Agent, 이하 LA)를 중심으로 구성된다. DDM은 모든 자료에 대한 현재 상태를 관리하는데, 자료의 등록, 수정, 삭제 등의 요구가 보조 에이전트를 통하여 실시간으로 이루어지며 자료의 통합 관리와 백업 관리는 주 에이전트가 담당한다. 한편 DDM는 자바와 JDBC를 사용하여 구축함으로써 임의의 플랫폼과 데이터베이스를 이용할 수 있게 하였다.

This service uses beacon with BLE technology, and USER APP has priority with Anchor IPS which secures location and device. Since then, it has been linked with character beacons that can be used in various places. The character beacon which is recognized as a service is able to confirm the user's location through API key of the LBS CMS server, and receives various contents services of the UESR CMS server. The service network consists of character beacon, Anchor IPS, USER APP, LBS CMS server, and USER CMS server. The purpose of the service is to promote local tourism and local culture to tourists through local unique characters.

This paper describes a design and implementation of monitoring applications on shipboard integration network. A wrapping module is designed to reuse pre-developed communication library of shipboard integration network. By using the wrapping module, monitoring applications are also designed to display several kinds of shipboard data. They are implemented and tested on general PC and embedded PC to verify that they can be applicable to different platforms.

In order to understand the concepts of image processing with effect, a learning system with an actual practice is necessary. As most image processing learning materials have some inconvenient respects that it is difficult to understand the processing procedure because they simply show the processed results as figures in the contents, and also, a separate practice tool is needed to operate the source codes because they provide the program source codes as a part in the context. In this paper, in order to solve above inconvenient respects, an image processing learning system that be able to improve the learning effects as accomplishing the theory studying and the actual practice in parallel is proposed. As this system is composed on the bases of java, it is independent to the platforms and it is possible to implement on the Web.
