Since the marking robot draws lines by point-to-point operation, the robot's shifting path greatly affects the working time and productivity. Therefore, it is required to analyze the movement method based on the robot's motion and plan to minimize the movement time. Therefore, this study proposes a method that can optimize the robot's shifting path to minimize the working time of the marking robot. Through the results of this study, it is expected that the non-working time of the marking robot will be reduced and the efficient operation will be possible.

In the process of ship building, it is known that the maintenance of working period and saving cost are one of the important part during the logistics of blocks transportation. Precise operational planning inside the shipyard plays a big role for a smooth transportation of blocks. But many problems arise in the process of block transportation such as the inevitable road damage during the transportation of the blocks, unpredictable stockyard utilization of the road associated with a particular lot number, addition of unplanned blocks. Therefore, operational plan needs to be re-established frequently in real time for an efficient block management. In order to find the shortest path between lot numbers, there are several representative methods such as Floyd algorithm that has the characteristics of many-to-many mapping, Dijkstra algorithm that has the characteristic of one-to-many mapping, and the A* algorithm which has the one-to-one mapping, but many authors have published without the mutual comparisons of these algorithms. In this study, some appropriate comparison have been reviewed about the advantages and disadvantages of these algorithms in terms of precision and cost analysis of calculating the paths and planning system to operate the transporters. The flexible operating plan is proposed to handle a situation such as damaged path, changing process during block transportation. In addition, an operational algorithm of a vacant transporter is proposed to cover the shortest path in a minimum time considering the situation of transporter rotation for practical use.

This study is searching the characteristics of transferred element in composition of architectural spaces ; it is ultimate goal that frame of reference is arranged system about path of horizontal direction is two-dimension and stairs of vertical in three-dimension as transferred element in Architectural plan. With the exception of stylized discussion or rhetorical analysis about these, it is analysed as element in physical order of a whole architecture in relation to another elements in composition of architecture spaces. And one who is perceptible and cognitive through spaces is the subject. Consequently , these elements are classified concept of location and circulation. And it can't think that the formal is divided the latter for accept behavior of pedestrican and thinking system to consider verticality and time property is absolutely conceptual elements in space of architectural plan.

In order to make good educational circumstance of the Technical High-school, it is important that we must aware of the characteristics of technical high-school and take all considerations into the planning. This study is to plan the architectural space and path of flow in practice rooms through questionnare survey. The result are as follow. A majority of respondents recognize that the existing facility and space condition are not appropriate, because the past investment has overemphasized on the quantitative aspect. It is time to need the change of its directions toward the quantitative investment in future. It is also necessary to plan the space and the path of flow of the practice rooms in consideration of the characteristics of school.

We have built a robot soccer system to participate in MIROSOT97. This paper represents hardware specification of our system and our strategy. We select a centralized on-line system for a soccer game. The paper explains hardware specifications of our system for later development. Also, the paper explains our strategy from two viewpoints. From the viewpoint of cooperation, some heuristic ideas are implemented. From the viewpoint of path plan, Cubic spline is used with cost function which minimized time, radius of curvature for smoothness, and obstacle potential field. Direct comparison will be realized in MIROSOT97.

Given a certain target point, the mobile robot's navigation could be mainly considered about two areas, 'how fast and accurate' and 'how safe'. Such problems regarding the velocity and stability possess close relationship with the path in which the mobile robot navigates in. Thus, the system proposed in this research paper was constructed so the mobile robot can obtain the optimum path by utilizing the information according to the environmental map, based on the Global Path Planning. Also by inducing the Local Path Planning method, it was constructed so that the robots can avoid the obstacles, which were not shown in the environmental map on-line. Particularly, by fusing the Local and Global Path Planning together, it is possible for the robots to plan similar path. At the same time, the focus was on the materialization of effective mobile robot's navigation. It was made possible by utilizing the Fuzzy Logic Control. Also, the validity of the algorithm proposed was proven through the trial experiment.

The purpose of this study is to compare and seize the type of the path of flow for nurses and living assistant, of the path of flow for evacuation and walking practice by analysis plan for the care facilities in the out-of-home service. It supposed many problem for living in the care facilities for the aged get down activity, especially their relates with difficulty in walking. And services of nurses and living assistant get mixed properties by that problem for the aged with difficulty in walking. It classified into T type, L type, H type, ${\Box}$ type, - type all the path of flow for nurses and living assistant on the longest from nursing station to each bedroom, the path of flow for evacuation from each room to exit, the path of flow for walking practice on the corridor and lobby. The three path of flow are influenced by an inner court, especially passable court is the important primary factor in the communication between the aged, a course and time required of flow.

The current drone flight plan creation creates a flight path point of two-dimensional coordinates on the map and sets an arbitrary altitude value considering the altitude of the terrain and the possible flight altitude. If the created flight path is a simple terrain such as a mountain or field, or if the user is familiar with the terrain, setting the flight altitude will not be difficult. However, for drone flight in a city where buildings are dense, a safer and more precise flight path generation method is needed. In this study, using high-precision spatial information, we construct a drone safety flight map with a 3D grid map structure and propose a flight path search algorithm based on it. The safety of the flight path is checked through the virtual drone flight simulation extracted by searching for the flight path based on the 3D grid map created by setting weights on the properties of obstacles and terrain such as buildings.
