Recently, there are lots of concerning on the integration of robot and virtual reality with the trends of the research of intelligent robot and mined reality. In this paper, a 3D GUI system is proposed based on Internet for remote controlling and monitoring of agent robot working for itself. The proposed system is consists of a manager ordering a new position and displaying the motion of robot, an agent robot moving to the destination according to the indication, a positioning module detecting the current position of robot, and a geographical information module. A user can order the robot agent move to a new position in a virtual space and watch the real images captured from the real sites of the robot. Then, the agent robot moves to the position automatically with avoiding collision by using range finding and a path detection algorithm. We demonstrate the proposed 3D GUI system is supporting a more convenient remote control means far the robots.

Open Decision Support System(DSS) is an automated and transparent system that is built to be shared both within and across organizations. The open DSS has been thought to be a set of decision components that are communicating through Web protocols. These characteristics intuitively invite the Web services concepts, which are currently one of the new trends in network-based business services. However, web services still are not active enough to be autonomous, and to provide for composing functionalities. These lead to the motivation on building a sophisticated web service to contain these features and to utilize web services on behalf of the user. This paper aims to propose a new concept of Meta Web Service, a web service-based open DSS. Decision modules in a dynamic and open DSS can be viewed as a web service. The Meta Web Service understands the users problem statement with ontology, performs web service discovery, web service composition, and automatically generates codes for composite web service execution. A prototype of example web service has been developed to show the feasibility of the proposed idea.

Systematic classification system for standardization in telecommunication is essential to the standardization R&D strategy. This paper suggests a new reference model for development of work area and classification scheme related to the telecommunications standardization : Cubic and matrix approach. Standardization Work Areas(SWAs) that are upper level of the reference model are classified by its main role and function reflecting the market trends and user needs. Standardization expertise is lower level scheme, which can be regarded as the different possible layers of standardization to be applied to each one of the SWAs grouped under upper level scheme. A new reference model consists of two planes that are SWAs plane and Standardization layer plane. Finally the reference model for classification of SWAs in telecommunication mapping onto matrix table that row and column are defined by SWAs and standardization layer respectively.

The environment which surrounds us such as climates, technology change rapidly. Forecasting the future of food by reviewing the subject at the moment would be meaningful, because we could understand the impact of new technology, set the new goal and create the future by speaking out on issues of our concern and by our choices. There are two points of view on our future, one is pessimistic view due to the food and the water shortage, as well as environmental contamination. Another is optimistic view mainly because of innovative technologies. Biotechnology would enable to develope the personalized food using nutrigenomics, nutrigenetics, and nutraceuticals. Nanotechnology and shelf-life extension techniques would contribute great deal to the development of the future food. Consumer's concern for the health and the wellness as well as palatability would affect the development of future food so that the involvment of food cookery scientists are more important to meet the consumer's needs and trends.

Some of the remarkable accomplishments mentioned in the special lecture recalling 38 years of my research on the development of herbicides can be summarized as follows; 1) The physiology, movement in the soil, and decomposition and/or inactivation of the phenoxy and other herbicides by the invention of the Raphanus test were elucidated. And these findings led to the establishment of the theory of herbicidal treatment layer with the result of the origination of the application of PCP in flooded lowland paddy, which opened new era of soil application of herbicides in lowland paddy. 2) The granulation of herbicides for lowland paddy including PCP urea was developed. 3) The fact that propanil has generic selectivity in gramineae was found. And propanil was distributed in rice growing regions of the world. In addition, satanil for upland and propanil/NAC for flooded lowland paddy, propanil mixtures, were developed. 4) 15 kinds of new herbicides derived from plant hormones developed in my laboratory were develop ed, and the research trends in the future were presented.

In 1980's to 1990's the marine propulsion diesel engines have been developed into lower speed and longer stroke for the energy saving(small S.F.O.C.). As these new trends the convetional mechnical-hydraulic governors were not adapted to the new requirements and the digital governors have been adopted in the marine use. The digital governors usually use the control algorithms such as the PID control, optimal control, adaptive control and etc. While the engine has delay time and parameter variations these control algorithms have difficulty in considering the stability and the robustness for the model uncertainty. In this study, the $H_{\infty}$ controller design method are applied to the speed control of the low speed marine diesel engine. By comparison the $H_{\infty}$ control results with the PID control results, the validity of the $H_{\infty}$ controller under the delay time and parameter variations is confirmed.

Recently 'full browsing service' is growing rapidly throughout the world. This service allows mobile phone users to access websites using their mobile phone as they do using a PC. Despite the rapid expansion of the mobile phone market, however, criteria or scales for evaluating the new services are being developed slowly and far behind the current demand trends. Thus, this study proposed a customer satisfaction evaluation model for full browsing services through empirical research. The proposed model is expected to derive and suggest key factors that users consider important in full browsing services and those factors can be used in developing marketing strategies for maintaining existing customers and creating new customers.
