This paper proposes an Object-oriented model for Generic Equipment Model(GEM) which is applied to semiconductor processing Equipment. A proposed implementation model for GEM consists of three modules : a module to convert SECS-II message and a module to transmit messages between GEM and a physical equipment. The proposed Object-oriented model for GEM has advantages in reuse and user management from the point of view of development program. Especially, this paper proposes a GEM agent COM, which is a base of GEM, transmits messages and events among modules. This Object-oriented model is analysed and developed by using UML.

This paper describes the universal-type signaling service equipment which provides a signaling service function (R2 MFC, DTMF, Continuity check tone, and Audible tone sending and/or receiving) for call processing control in TDX-10 switching system. Based upon the structure of the TDX-10 switching system, the philosophy of design and technology on the universal-type signaling service equipment has been investigated in order to realize a reduction in size and cost, as well as assuring high reliability and flexible operation. Finally, the control method, fuctional operation and principal feature of the designed universal-type signaling service equipment have been described.

In the study, Methods for operating measures in equipment security to find out dangerousness timely in the system and to need for the prevention and measures. The method for analyzing and reconstructing the causes of accident of equipment in site, and try to save the information of site in real-time and to analyze the state of equipment to look for the factors of accidents. By this analysis, one plan for efficiency of production, Equipment Fault Diagnosis Management and security is integrating and building module of using the Fuzzy Inference based on fuzzy theory. The case study is applied to the industrial electric motors that are necessarily used to all manufacturing equipment. Using the sensor for temperature is attached to gain the site information in real time and to design the hardware module for signal processing. In software, realize the system supervising and automatically saving to management data base by the algorithm based in fuzzy theory from the existing manual input system

Recently, the tracking radar continues research to develop a new operation algorithm that can acquire and track a target in various environments. In general, modeling similar to the real target and environment is used to develop a new operation algorithm, but there is a limit to modeling the real environment. In this paper, a RAW data storage device was developed to efficiently develop a new operation algorithm required for the tracking radar using millimeter wave to acquire and track the target. The RAW data storage equipment is designed so that the signal processing device of the tracking radar using millimeter wave can save the RAW data output from 8 channels to OOOMSPS. RAW data storage equipment consists of data acquisition equipment and data storage equipment. The data acquisition equipment was implemented using a commercial Xilinx KCU 105 Evaluation KIT capable of high-speed data communication interface, and the data storage equipment was implemented by applying a computer compatible with the commercial Xilinx KCU 105 Evaluation KIT. In this paper, the performance of the implemented RAW data storage equipment was verified through repeated interlocking tests with the signal processing device of the millimeter wave tracking radar.

An alarm gathering interface equipment has been developed to collect the hardware failure activities in 1$1, 024\times1, 024$ ATM switching system. The equipment use 8-bit microprocessor and ELA-232C port, and is fabricated in a single board, which called Alarm Gathering Interface board Assembly(AGIA). It is programmed to ensure flexibility in modification and expansion of the system capability. The performance is successfully proved through communication test with hardware blocks or modules consisting a ATM switching system, these techniques can be used to develop operation and maintenance functions for more superior ATM switching system in the near future. we additionally have presented some items for further study on alarm subsystem often ATM switching system.

This paper proposes the architecture and major functionalities of IT converged smart outdoor exercise equipment and health cashback system. It provides basic information such as date, time, weather information, and display the amount of exercise, thermal images for monitoring the change of user's body temperature and health cashback point. The amount of exercise is transferred to a health cashback server via mobile communication network and the server provides the exercise history and health cashback point. Also, as additional public services, a fine dust alarm light and an emergency alarm function are embedded. The proposed IT converged smart outdoor exercise equipment will be a reference model for studying and commercializing the next generation product.

In this paper, we suggest the basic components of monitoring system for the semiconductor wafer cleaning equipment and a monitoring system model based on these components. Basic component is defined as a mandatory function which consists of communication with the control system, user interface, communication with the remote monitoring system, management of monitoring data and inter-task communication. We have defined the function of each component and the relation among them, and designed each component as a task. To evaluate the validity of the suggested model, we have implemented the basic components using the Visual C++ on Windows NT and applied them to the Monitoring System for the semiconductor wafer cleaning equipment.

A new concept ？？soft solution processing？？ has been introduced to fabricate advanced solid state materials in an economical, environmentally friendly, and energy and material efficient way. The prepared films show the desired and prospective properties despite of low temperature synthesis and no post-synthesis annealing. Successful examples demonstrate that soft solution processing is capable of preparing advanced materials with planned properties through the easy control of reaction conditions in a suitable aqueous solution in a single synthetic step without huge energy consumption and without any sophisticated equipment.
