An advanced real-time satellite simulator (ARTSS) has been developed to support the ground operations activities of the ETRI satellite control system, such as testing of the system facilities, validation of flight control procedures, verification of satellite commands as well as training of the ground operators. The design of ARTSS is based on the top-down approach and makes use of a modular programming to ensure flexibility in modification and expansion of the system. Graphics-based monitoring and control facilities enhance the satellite simulation environment. The software spacecraft model in ARTSS simulates the characteristics of a geostationary communication satellite using a momentum bias three-axis stabilization control technique. The system can be also interfaced with a hardware payload subsystem such as Ku-band communication transponder to enhance the simulator capability. Therefore, ARTSS is a high fidelity satellite simulation tool that can be used on low-cost desk top computers. In this paper, we describe the design features, the simulation models and the real-time operating functions of the simulator.

It is known that to automate the quantity take-off process enables you to increase the productivity best among the construction business field. However, the limitation of 2D(Two-dimension) CAD System prevented a cost-estimating system which makes the great effects on the quantity take-off process from being developed. This study aims that you can automate both the itemized statements and the quantity take-off process by using commercially available object-oriented CAD system. The commercially available CAD system today does not give us entire satisfaction. This study shows the deduction of the old boundaries of the object-oriented CAD system and the solution of those problems. And it also studied about the quantity take-off process and the automated cost-estimating system that can be used in the simple and plain repair-maintenance work such as the execution drawing which doesn't need the complicated drawings.

In this paper, the cupola heat balance has been carried out by using programmable calculator with BASIC language. Computers tend to be used in almost every fields but for many people, computers are not handy yet because of its high equipment cost and its difficult language system. In view of this fact, a desk-top or a hand-held programmable calculator is the pertinent device in its calculation speed, accuracy, and easy programming language (BASIC), let alone its low cost. There have been some attempts to apply them to the foundry,${^{1),2)}}$ but they are little in number. This paper is the first attempt to apply the programmable calculator to the calculation of the cupola heat balance. After several applications in some practicalcases, the program has resulted in very satisfactory results such as saving of time and accuracy.

With installation of the computerized data acquisition system on the towing carriage of KRIS towing tank, the testing techniques of resistance test, propeller open-water test, self-propulsion test and wake survey at propeller disk were remarkably improved and automated. For the self-propulsion test a new method was developed with aid of a digital desk-top computer. This method is based on extracting advantages both from British method and Continental method, that is, the accuracy from the constant speed method and the effciency from the constant load method. The KRIS method has been successfully practized with the improved accuracy, stability and efficiency. Details of the new method are described in this paper.

The treatment of chronic digital pain and cold intolerance due to Raynaud's phenomenon is quite difficult especially it is combined with scleroderma. Several surgical trial such as cervicothoracic sympathectomy have been attempted for the medically unresponsible Raynaud's phenomenon, but their results were unsatisfactory. We have tried peripheral periarterial sympathectomy for the 44 years old female patient who had medically unresponsible severe Raynaud's phenomenon with scleroderma. Periarterial adventitial stripping was performed at the level of wrist, superficial palmar arch, common digital artery and proper digital artery about 1.5-2 cm in length. Preoperative angiography and radioactive angiography were done and preoperatively and postoperatively the blood flow was measured by the desk top computer-aided histogram. Both hands digital pain were markedly reduced after operation and blood flow increased as compaired with the preoperative measure.

The safe passing maneuver of a large vessel along the designed course through a narrow channel in the flow of strong current is greatly related with her maneuvering characteristics. This paper treats maneuvering characteristic of a large vessel changing her course with the use of her control surface in a narrow channel with strong current. In this paper, the author proposed mathematical models of calculating maneuvering motions of the very large LNG tanker altering course using her control surface and calculated passing tracks of the vessel through the channel and compared the calculated results with those of maneuvering simulations by a desk-top simulator. In general the motions with the calculated values and the simulated motions are well coincided with each other.

In this study, micro tools(WC) to produce micro-structure and parts, were fabricated ell a cylindrical grinding machine using ELID(Electrolytic In-process Dressing) technique. The shape of the micro-carbide tool was square, corn. The size of the micro-carbide tool was measured less than 10$\mu\textrm{m}$ respectively by SEM(Scanning Electron Microscope). Furthermore, we fabricated micro structure by different processing methods on the desk top cylindrical grinding machine. The manufactured shape was like a tower and the measurement showed that the endpoint of micro structure was $50{\times}50$$\mu{\textrm}{m}$.
