This paper describes our ongoing Korean-Chinese machine translation system, which is based on verb patterns. A verb pattern consists of a source language pattern part for analysis and a target language pattern part for generation. Knowledge description on lexical level makes it easy to achieve accurate analyses and natural, correct generation. These features are very important and effective in machine translation between languages with quite different linguistic structures including Korean and Chinese. We performed a preliminary evaluation of our current system and reported the result in the paper.

The mining-related damages such as ground subsidence, acid mine drainage(AMD), and deforestation in the abandoned underground coal mine areas become an object of public concern. Therefore, the system to manage the miningrelated damages is needed for the effective drive of rehabilitation activities. The management system for Abandoned Underground Coal Mine using GIS includes the database about mining record and information associated with the mining-related damages and application programs to support mine damage prevention business. Also, this system would support decision-making policy for rehabilitation and provide basic geological data for regional construction works in abandoned underground coal mine areas.

The KSTAR(Korea Superconducting Tokamak Advanced Research) superconducting magnet system consist of 16 TF(Toroidal Field) and 14 PF(Poloidal Field) coils. Internally-cooled cabled superconductors will be used for the magnet system. The magnet system adopt a superconducting CICC (Cable-In-Conduit Conductor) type. The KSTAR PF 6, 7 CICCs use NbTi Superconducting cable with stainless steel 316LN conduit while the other PF CICC use Incoloy 908 conduit. For the fabrication of PF CICC, superconducting cables have been fabricated and the cable has the diameter of 22.3mm. A continuous CICC jacketing system is developed for the CICC jacketing and the jacketing system uses the tube-mill process, which consists of forming, welding, sizing and squaring procedures. The cabling and the jacketing process is described. The welding condition and design specification of CICCs are also discussed. The fabrication results including the geometrical specification and the void fraction will be discussed.

The optics used in an infrared imaging system has a strong refractive-index change according to temperature, so an autofocus control function is essential for a military infrared imaging system with a wide operating-temperature range. In this study, we design a triple-magnification infrared imaging system, and to compensate for the change in refractive index according to temperature we measure the change in the lens focus according to temperature. The autofocus control function was implemented by using the measured movement amount, and we could obtain an image with satisfactory resolution performance over a wide range of operating temperatures.

MMI system for strip caster 2 is described. It has been developed as a PC-based MMI system whose data is collected from the VME-based control system by ETHERNET. MMI elements that mimic the caster and its utilities are designed by using commercial program. In order to implement the UDP/IP communication in MMI, UDP/IP manager program with DDE that is a intercommunication protocol in MS-window is developed and connected with MMI mimics. Operator commands in MMI system are carried out immediately in VME system and the responses are displayed on MMI system. The developed MMI system has been proven to be convenient and stable through the operation of the past 5 years.

According to the Korea Augmentation Satellite System (KASS) system milestone, Site Acceptance Test (SAT) has three steps test until the end of the project. SAT#1 is the first time of SAT steps and verify the KASS Reference Station (KRS) and Sub System (S/S) for the monitoring and controllable. After the equipment and software were installed at the Mission Control Center (MCC) with Central Monitoring and Control Simulator (CMS) for the SAT#1, the 1:1 test was progressed when the KRS and S/S are ready to test. SAT#1 has a 10 steps test case and it was progressed each KRS sites. The test was finished throughout the real-time monitoring and the data collection including the data analysis all of the 7 KRS sites. Finally SAT#1 was completed on December 2020 with successfully.

A tomography system using microwave multi-channel transceiver was fabricated and measured. The tomography system is applicable to detection of breast cancers in a human body. This system is configured by microwave muiti-channel transceivers, a illumination chamber housing monopole antennas and coupling liquid, and image reconstruction algorithm solving inverse scattering problem.

PACS is one of the most used medical information system and share information from other hospitals through the PACS. Data integrity means zero defects data and this is a prerequisite of information system performance. but I wonder if I can trust these informations that Incorrect information from radiotechnologist's mistakes, anonymous in emergency department, Newborn baby department, modified informations at later. And Modified informations causes defect in integrity of the data. When we import, we use DICOM header not DB data. so error occurs that DB data is deferent with DICOM Header information. This paper discusses to resolve as above problem using DICOM object such as DICOM PR, SR. And propose quality management system that can guarantee the patient information and can manage exam history.
