In the ubiquitous computing environment, an intelligent vehicle is defined as a sensor node with a capability of intelligence and communication in a wire and wireless network space. To make it real, a lot of problems should be addressed in the aspect of vehicle mobility, in-vehicle communication, common service platform and the connection of heterogeneous networks to provide a driver with several intelligent information services beyond the time and space. In this paper, we present an intelligent information system for managing in-vehicle sensor network and a vehicle gateway for connecting the external networks. The in-vehicle sensor network connected with several sensor nodes is used to collect sensor data and control the vehicle based on CAN protocol. Each sensor node is equipped with a reusable modular node architecture, which contains a common CAN stack, a message manager and an event handler. The vehicle gateway makes vehicle control and diagnosis from a remote host possible by connecting the in-vehicle sensor network with an external network. Specifically, it gives an access to the external mobile communication network such as CDMA. Some experiments was made to find out how long it takes to communicate between a vehicle's intelligent information system and an external server in the various environment. The results show that the average response time amounts to 776ms at fixed place, 707ms at rural area and 910ms at urban area.

This study concerns the design strategy for the waterside of Gyeong-In Ara Waterway, Korea’s first constructed canal. This design focused on the creation of a new paradigm for waterway landscapes the major factors of which were geographical advantage, value of landscape and efficient approach. As the major space plan for the waterfront formed through the Gyeong-In Ara waterway from the Yellow Sea to the Han River, eight good views of the waterfront zone were designed by utilizing the waterway as a scenery viewpoint and, by constructing two traffic lanes for the scenic parkway connecting Incheon and the Gimpo terminal, both a linear greenway as well as various waterfront facilities were also designed. A boardwalk and bike path connecting the major theme parks were planned, and a waterfront pocket park was then organized based on the bike path. In this study, the result of the new waterfront result from the Gyeong-In Ara waterway was planned to have an identity as a new waterside culture space in order to achieve multiple functions including environmental, cultural, leisure, and tourism as well as management programs based on a variety of applied culture content and story-telling.

In 21 Century, people's living standards and material requirements have been continuously improved with the development of society. The demand for commercial space is not merely content with purchases. What's more, the consumers want to experience some activities offered by the brand while shopping. In this paper, we mainly research the spatial structure and the spatial expressional characteristics of brand lifestyle shop of Korean brands built in Seoul area. First, through the documentary research, we get the four characteristics of interior space performance of brand lifestyle shop, which are, interaction, proximity, symbolism and compound. Secondly, we select 8 brand lifestyle shops in the Seoul area as the object of this study, and analyze the actual application of the four characteristics in these cases. Thirdly, through the analysis of case study, we make a concrete analysis of the expressional characteristics of Korea's brand lifestyle shop. Finally, we reach the conclusions: First, the brand lifestyle shop provides space for both brands and consumers to communicate with each other. Second, in brand lifestyle shop there is a special space which is different from the other commercial space. The existence of this special space makes brand lifestyle shop more personalized and more specialized, and makes the customers have more interesting when they are shopping. Third, compared with the sales space, the non-sales space accounts for a larger proportion. Fourth, in spatial representation, interaction plays a role in connecting brands with consumers. Fifth, brand lifestyle shop has the same spatial concept, but it has different application and embodiment in each case. Each brand lifestyle shop has its own unique features. This is the economic strategy used by brand sustainable development and expansion.

This article describes a snake robot with 2-DOF actuator modules. The 2-DOF actuator modules make the snake robot move in the 3D space so that the snake robot can cross obstacles and rough terrain. Each 2-DOF actuator module is designed to have high torque output and an embedded controller. A cross bracket connecting the modules is designed be able to support the weight of two actuator modules. The developed snake robot shows 3-D motions such as side winding, standing/monitoring, and can climb in a narrow pipe with high torque modules. The snake robot moves fast with passive wheels in a plane while crossing obstacles.

This paper presents a practical technique for approximating the boundary surface of the volume swept out by three-dimensional objects using the depth-buffer. Objects may change their geometries and orientations while sweeping. The sweep volume is approximated as a union of volume elements, which are just rendered inside appropriate viewing frusta of virtual cameras and mapped into screen viewports with depth-buffer. From the depth of each pixel in the screen space of each rendering, the corresponding point in the original world space can be computed. Appropriately connecting these points yields polygonal faces forming polygonal surface patches approximately covering some portion of the sweep volume. Each view frustum adds one or more surface patches in this way, and these presumably overlapped polygonal surface patches approximately enclose the whole sweep volume. These patches may further be processed to yield non-overlapped polygonal surfaces as an approximation to the boundary of the original 3D sweep volume.

Through the rapid growth of Korea for the effectiveness and rationalization of the use of land the development of the underground land is mostly needed. Especially I think that in the limited country(like Korea) when we consider that the population of metropolitan area is almost a third if a total population of this country it is time that we should consider the method of transfer for using of under ground not of on the ground from the legal or systematic recognition of the land. In this respect it is necessary that the person involved in the urban development (the person for architect urban development landscape architect and adminstratives) should pay much attention to the using of the underground spaces.

It is well observed in the satellite telecommunication policy of several States that legal constraints imposed upon the service coverage of satellite telecommunication as well as broadcasting are to be relaxed in a progressive way. Major aspects of such policy change lie in the adoption of policy refusing traditional concept of national frontier. In the case of direct broadcasting satellite service, while a debate upon the legal issues regarding the spill-over effect of that service is no more major concern of the States, many multinational enterprises are looking for strategic alliance for regional or global DBS project. On the other hand, an implementation plan for connecting the world through global mobile personal communication satellite system is being pursued by several joint effort of multinational firms. Legal issues arise regarding the regulatory competence of each State, Especially, a controversial issue is concerning the sovereign right well recognized upon the regulation of telecommunication. This study is focusing upon the evolution of such policy change for the purpose of allowing us to expect future develpment of worldwide satellite telecommunication policy environment.

This research focuses on developing a new and computationally efficient algorithm for free space structuring and planning collision free paths for an autonomous mobile robot working in an environment populated with polygonal obstacles. The algorithm constructs the available free space between obstacles in terms of free convex area. A collision free path can be efficiently generated based on a graph constructed using the midpoints of common free links between free convex area as passing points. These points correspond to nodes in a graph and the connection between them within each convex area as arcs in this graph. The complexity of the search for collision free path is greatly reduced by minimizing the size of the graph to be searched concerning the number of nodes and the number of arcs connecting them. The analysis of the proposed algorithm shows its efficiency in terms of computation ability, safety and optimality.
