Effective use of agricultural informations is crucial for 21 century farming. An interactive agricultural machinery information system was developed. It consisted of databases, knowledge bases, expert systems, a server engine, clients for a multimedia agricultural machinery information system based on Java and distributed objects technology. It is supposed to be served through a nationwide super information communication network for my farmers to utilize it interactively and quickly. Several user-friendly interface programs for users were developed to use texts, static k dynamic images, and expert systems easily. Tools for providing the informations were built with JAVA. Information providers permitted to access to the system such as agricultural machinery companies can easily add or modify the informations using distributed object technology. This system can interact among three groups : prime information provider (or system manager), permitted information providers, and farmers.

초고속통신망의 확대와 인터넷 사용자의 증가로 인해 가상공간상의 교육, 오락, 문화 등 콘텐츠의 다양성 및 효율성에 대한 요구가 증대되고 있다. 대부분 가상공간상의 놀이공원은 2차원적인 한계를 벗어나지 못하고 있는 실정이다. 이러한 2차원적인 구조는 사용자들이 놀이공원에 대한 정보를 스스로 찾아보아야 하며 흥미를 유발하는데 한계가 있다. 즉, 엔터테인먼트 분야에는 적합하지 않은 인터페이스 구조인 것이다. 본 논문에서는 3차원적인 인터페이스와 3D 아바타가 주도하는 가상놀이공간을 구축한다. 사용자가 능동적으로 참여하고 즐길 수 있는 생동감 있는 web3D 기반 인터렉티브 콘텐츠를 개발한다.

An Interactive grid generation program(KGRID) with graphical user interface(GUI) has been improved. KGRID works on the UNLX environment and GUI has been implemented with OSF/Motif and X Toolkit and the graphics language is Open GL for visualization of the 3D objects. It supports more convenient user environment to generate 2D and 3D multi-block structured grid systems. It provides various useful field grid generation methods, which are the algebraic methods, the elliptic partial differential equations method and the predictor-corrector method. It also supports 3D surface grid generation with NURBS(Non-Uniform Rational B-Spline) and various stretching functions to control grid points distribution on curves and surfaces. And some menus are added to perform flexible management, for the objects. We generated surface and field grid system about full aircraft configuration using KGRID. The performance and stability of the KGRID is verified through the generation of the grid system about a complex shape.

3D 집적 영상 기술은 연속적인 시점, 완전 시차와 풀칼라 영상을 공중에 표현하는 유망한 기술이다. 본 논문에서는 한 대의 카메라를 이용한 새로운 형태의 인터렉티브 3D 집적영상 시스템을 제안한다. 이 장치는 기존의 3D 집적 영상 디스플레이 시스템에 단순한 한대의 카메라를 추가적으로 사용하여 유저 인터페이스가 구현될 수 있다. 제안하는 시스템의 가능성을 보이기 위해서, 실험적인 장치 구현을 수행하고 기초적인 실험 결과를 보고한다.

This paper presents the development of an interactive knowledge-based CAM system for design-ing and manufacturing the mold. The system is composed of two functional parts. One is the geo-metric modeller that uses the feature-based models. The models include base plate step, hole, pocket, boss and slot, These are designed by interactive user interface. The other is the expert sys-tem module with inference engine and knowledge database of workpiece material tools manufac-turing machines process an working conditions. With two parts the final mold shape is generated with manufacturing information for effective production.

In this letter, we introduce a new middleware architecture and its generic application programming interface (API) (called the T-DMB MATE API) for terrestrial digital multimedia broadcasting (T-DMB). Middleware in T-DMB enables inter-operable applications to be downloaded from both broadcast and telecommunication networks in advance and to be executed in any type of T-DMB receiver. The middleware we introduce here is especially designed to support a proposed method for application provisions applied to a concept of application module appropriate to the service environment of T-DMB. We also verify the designed T-DMB MATE API through the implementation of the middleware and its application in a PC-based receiver.

Fe-Co-Ni particles with an average size of 45 and 135 nm are characterized in terms of magnetic phase transformation and magnetic properties at room temperature. BCC structure of Fe-Co-Ni spherical particles can be synthesized from Fe-Co-Ni-Al-Cu precursor films by heating at 600-80$0^{\circ}C$ for the phase separation of Fe-Co rich Fe-Co-Ni particles, followed by a post heating at $600^{\circ}C$ for 5 hours. The average size of nanoparticles was directly determined by the thickness of precursor films. Exchange interactive hysteresis was observed for the nano-composite (Fe-Co-Ni)+(Fe-Ni-Al) films resulting from the short exchange interface between ferromagnetic Fe-Co-Ni particles surrounded by almost papramagnetic Ni-Al-Fe matrix. Arraying the isolated Fe-Co-Ni nano-particles in a random arrangement on $Al_2O_3$substrate the particle assembly showed a behavior of dipole interactive ferromagnetic clusters depending on their volume and inter-particle distance.

Digital technology makes changes of people's behavior style and characteristic of space in which people live. Therefore, we need to adjust conceptual meaning related to digital technology properly. For deriving emotional interactive space design, we need to understand following meanings: the meaning of interaction and interaction design, the meaning of emotion and emotional design, the meaning of space, emotional design, and interaction design in digital society. Consequently emotional interactive space design makes people satisfied with their five senses, communication with people increase and enable people to experience something new that they haven't experienced before transcending time and space.

Advances in interactive multimedia and Internet technologies present an array of options that allow the development of very effective training programs. Interactive training is the delivery and management of training using Internet. The trainee actively participates in the training/learning sessions by means of a user-friendly interface that empowers the participant with a sense of control over what they are teaming and the pace at which they are teaming. In this paper, we show process on the development of 3 dimensional e-learing system for Ubiqitous Environment using 3 dimensional supersonic sensor.

This study examines the response of users' feelings from a gender perspective toward interactive video mobile learning (IVML). An IVML prototype was developed for the Android platform allowing users to install and make use of the app for m-learning purposes. This study aims to measure the level of feelings toward the IVML prototype and examine the differences in gender perspectives, identify the most responsive feelings between male, and female users as prominent feelings and measure the correlation between user-friendly feeling traits as an independent variable in accordance with gender attributes. The feelings response could then be extracted from the user experience, user interface, and human-computer interaction based on gender perspectives using the Kansei engineering approach as the measurement method. The statistical results demonstrated the different emotional reactions from a male and female perspective toward the IVML prototype may or may not have a correlation with the user-friendly trait, perhaps having a similar emotional response from one to another.
