In this paper, we introduce an integrated communication and control system(ICCS) for control of a crane. The system is integrated with a compasite technique as a network interfacing, a user interfacing and a system control for continuous process like as a container crane. The field-bus(Profibus) network module is used to interconnect each input/output module with main control unit. The MMI system for user interfacing is integrated with an ODBC-based data management tool and IECl131-based control logic design tool(Soft-Logic Designer:SLD). The each programmed control task in the main Controller is executed using a petri-net based scheduler.

We demonstrated micro-scale conducting polymer patterning based on a selective surface treatment. A substrate with a patterned photoresist was immersed into OTS (Octadecyltrichlosilnae) solution. The protected substrate areas were hydrophilic after removing the PR resist, where a conducting polymer solution was coated selectively by spin-coating method.

EMU Traction Control System has been largely relied on foreign technology until now. In this time, this system is developed by own local technology according to national technology development policy during 3 years. In this paper, the new developed Traction Control System of EMU and its testing results are introduced. The Traction Control System is consisted latest IGBT switching elements and its traction control algorithm is realized by the state-of-the-art technology, vector control. The system is fully tested in various conditions and the quality is well verified in those tests.

In this study, We evaluated the efficiency of the smart ventilation system being developed at the test-bed(KCL). Smart ventilation system improve the indoor air quality by absorbing carbon dioxide. It is reducing the infusion of outside air can be reduced to minimum energy consumption. To evaluate the energy savings and carbon dioxide removal efficiency. It was more effective when working with air conditioning and ventilation system at the same time.

A blind system for window glass has been designed and manufactured as a CapStone Design project at Seoul National University of Science and Technology. This system automatically controls the interior illuminance to maintain a uniform temperature. The aim of this project was to support an air conditioning system and heating equipment to maintain a good indoor environment. Proportional integral differential (PID) control using cadmium sulfide (CdS) sensors was applied to control it. Polaroid film was attached to the new blind system to reflect sunlight. It was found that the system had the potential to reduce energy consumption and may be used with a building energy management system (BEMS).

There has been much interested on the issues of designing and implementing the data acquisition and display system. This paper describes how to acquire and manage the data to be generated from sensor sources in a manufacturing process. The functionality of this data management system is composed of data acquisition, database management, processing and display of the available data. Also, this system has a adaptability to be carried throughout configuration management.

Though a demand for 3-D CG (Three-Dimensional Computer Graphics) drastically increases, traditional modeling system for virtual objects are very difficult to handle. Applying VR (Virtual Reality) technology is, however, able to make the modeling systems more efficiently and intuitively. In this paper, traditional modeling operations are analyzed and their problems are clarified. We discuss what can be improved with VR technology. Then, a guideline of merging VR technology into the modeling system is described. A new modeling system is proposed using a CAVE system which is utilized in the latest VR technology. This proposed system aids in creating 3-D objects with high immersion in VEs (Virtual Environments)

Airborne infrared techniques have been used in wild land fire management for decades. This paper describes a kind of infrared scanning system based on a rotating drum with a tilted porthole underside the plane nose. This design increases the stability of the mechanism system, reduces air resistance and protects inner parts. Aberration characteristics of a tilted ellipsoid porthole are analyzed and an effective solution is invented which makes the system achieve $30^{\circ}$ field of regard. The system's ultimate value of modulation transfer function is near the diffraction limit, which indicates that the performance of the rotating optical system meets the imaging requirements.
