  • 본 논문은 국가직무능력표준(NCS)기반 국가기술자격검정의 용접분야 실기시험 평가방법 개선을 목적으로 수행된 연구에 대한 내용을 기술한 것이다. 현행 용접기능장의 실기시험 내용을 체계적으로 분석한 후 최신 용접기술 동향을 반영하고 국가직무능력표준의 능력단위, 수행준거 등을 적용하여 용접기능장 실기시험의 새로운 평가방법을 제시하였고, 자문회의 및 시범평가를 통해 그 효과를 검증하였다. 향후 한국산업인력공단 기술자격출제실에서는 본 연구를 기초로 세부직무분야 전문가를 통한 출제 기준 개정을 완료 한 후 용접기능장 국가기술자격검정에 실제 적용할 예정이다.

  • 음성급 서비스 위주로 설치되어 있는 국내의 구내통신 설비는 서비스와 무관한 접지 및 본딩에 관한 제방 규정이 미비한 상황이다. 고속, 광대역 서비스용 구내통신 설비의 신뢰성 제고를 위해 구내에 설치되는 기자재의 접지와 본딩에 관한 연구 및 표준안 작성을 구내통신운용의 효율성을 도모하기 위해 꼭 필요한 분야이다. 따라서 본고는 국내 접지현황 및 문제점을 고찰하고, 이에 비교할 만한 국외의 여러 접지 및 본딩에 관련한 기술표준을 살펴 본 후, 국내의 취약한 부분에 외국의 기술표준을 적용한다. 결과적으로 건물의 신/개축 시 구내통신설비에 맞는 접지와 본딩의 국내 기술표준안을 제시하여, 신뢰성있는 시스템을 제공하도록 관련된 모든 분야에 일반성과 효율성을 부여하고자 한다.

  • It is reported that, admitting some of the Small and Medium Industries in Korea have world-wide up-to-date technology, but technical competitiveness of most of Industries is approximately 43% that of advanced countries. A research has been carried out to evaluate technical competitiveness of the Small and Medium Industries in Kangwon Province based on the objective standards. It is identified that competitiveness of technology is higher in general while capability of technical development is relatively lower.

  • As the European Union has strengthened and computerized signalling systems have been widely used, the European common standards for the safety of railway signalling systems such as EN 50126, EN 50128, ENV 50129, EN 50159 began to be published from 1996 in CENELEC. At that time, a safety guideline, 'Safety Guidelines for Computerized Train Control and Protection Systems' was published in Japan. The Korean National Railroad also published a safety recommendation for the train control systems with taking into account the Korean railway conditions. Now the preparations for IEC/TC9 Standards are well underway and these standards correspond to CENELEC Standards referred above. These movements and activities are to cope with many technical and operational changes and to reflect the globalization trend of railway sectors along with the computerization of signalling devices. In this connection, this paper studies the globaliztion trend in the safety standards for railway signalling systems and discusses the counterplans for the trend.

  • Electric activity of cardiac muscles generates magnetic fields. Magnetocardiography (or MCG) technology, measuring these magnetic signals, can provide useful information for the diagnosis of heart diseases. It is already about 40 years ago that the first measurement of MCG signals was done by D. Cohen using SQUID (superconducting quantum interference device) sensor inside a magnetically shielded room. In the early period of MCG history, bulky point-contact RF-SQUID was used as the magnetic sensor. Thanks to the development of Nb-based Josephson junction technology in mid 1980s and new design of tightly-coupled DC-SQUID, low-noise SQUID sensors could be developed in late 1980s. In around 1990, several groups developed multi-channel MCG systems and started clinical study. However, it is quite recent years that the true usefulness of MCG was verified in clinical practice, for example, in the diagnosis of coronary artery disease. For the practical MCG system, technical elements of MCG system should be optimized in terms of performance, fabrication cost and operation cost. In this review, development history, technical issue, and future development direction of MCG technology are described.

  • The BIM libraries and technical contents in order to develop common technical standards that reflect the contents for a BIM design support should be based. It is essential to redress the technological burden on design office requirements. The technical contents consisted of Material Information, Standard Details and Cost Information are made by system of standard classification. By connecting BIM libraries with each of information including the contents, it derives the consistent BIM data application through the integrated model. In addition, we look forward to introducing and applying BIM more easily through securing common technical contents which remove the pressure of engineering developments of each individual architectural design office and prevent overlapping investments.
