  • A grounding scheme is one of important parts in protection for safety of electrical installations. Terminologies are successively creating and gradually increasing due to diversity and external environments. The declaration and definition of terminologies concerning grounding are in disorder in several KS standards, electrotechnical provisions for electrical installations and electrotechnical guides related to electrical installations. There seem to be serious confusions in use among technicians and experts. In this paper, we proposed a new scheme and system to consistently use the technical terms concerning grounding described in KS standards and technical provisions. Different use examples and the present state of terminologies on grounding described in Korean documents such as KS IEC standards, technical provisions for electrical installations, consumer's electrical installation guide, and etc are investigated. Although the scope of this work is limited to examine the terminologies on grounding, it is expected that the proposed method could be contributed to the consistent use of terminologies in all areas in KS C IEC standards and technical provisions for electrical installations.

  • In this paper we introduce mathematical modellings in teaching and learning differential equations which were adopted by 2009 revised curriculum. The textbook of 'Advanced Mathematics II' published in 2014 with one publisher includes the content of the second order differential equation y"+y=0 by the power series method. This paper discusses the issue of the power series and gives an alternative method to explain problems of differential equation. Also, we found that the textbook of 'Advanced Mathematics II' used the mechanical system not electrical system in solving differential equation problems. Thus this paper suggests a method using an electric circuit in teaching and learning the first order differential equation. Finally we suggest some terminologies in the teaching and learning of differential equations.

  • Through the correspondence works with international electrotechnical vocabulary(IEV) in the smart grid field and power information technology field, we analyzed cases for discussion of terms and definitions in the IEV and then proposed an advanced procedure and computing system for standardization of International Electronical Committee(IEC) terminologies. The standardization procedure consists of processes for existing terminology, new terminology and correspondent terminology which have different structures. An example of the standardization work of correspondent terminology is given. The standardization computing system are based on the process for terminology extraction, terminology verification and terminology management which could provide the Wikipedia type terminology search function. In order to prevent that there exist multiple terminologies in IEV, the database search system is needed to be developed. We proposed the 'IEV_Term_Search' program which is the database search system. Terminology standardization of different technical committees(TC) and completion of the IEV to promote cooperation between TC 1 and the TCs must be followed by revision and standardization using the standardization computing system.

  • Through the correspondence works with IEC in the smart grid fields and power IT fields, we set up the interpretation work procedure and defined the work rule for correspondence by analyzing the work results. In addition, we suggest cases for discussion of terms and definitions in the IEC and analyze them and then propose a matrix classification system for standardization to solve the cases for discussion. The matrix classification system with 3-axes of classification has been applied to newly emerging terminologies followed by smart gird. We drew the usefulness in search of terms in application fields and showed the cases of applying the matrix classification. The IEC Electropedia classification standard is unclear and the classification is mixed with principle, application and product areas. We proposed a new working group in IEC TC1 for research on the matrix classification system and then TC 1 decided to organize a new WG titled in the "IEV structure and supporting tools".

  • As technology is developed, the quantity of new vocabularies is increasing more rapidly. So many vocabularies of technology have various meanings for each part and are used diversely according to circumstances. Therefore, the necessity of reasonable methods of standardization and purification is increasing and it is necessary to establish a classification system of terminology for the first phase of the standardization. Firstly, based on classification systems of power and IT standard dictionaries, scientific and technological standard, SPARK, power IT fields of IEC and organization units of corporations, we propose a new classification system for the standardization of power IT terminologies. The classification system consists of a hierarchical structure with general classification, application fields and specific technologies while keeping the conventional matrix-type classification system. And interpretation methods of power IT terminologies, which are classified according to the new classification system for the standardization of power IT terminologies, is proposed. The interpretation works of the power IT terminologies confirm that the classification system is systematic and the interpretation process is efficient.

  • Power system technologies in the area of smart grid are being converged with communication system technologies or information technologies(IT). This interdisciplinary action affects on two parts vigorously so that IT has become a essential part of power industry. But terminologies of two parts are confused and it is necessary that these are standardized to develop the industry. The writing system of the Open Korean Knowledge Dictionary for standardization of smart grid terminologies which are IEC TC 57 glossary and non-glossary is proposed. The writing system includes the process of collection, writing guideline and standardization of terminologies. Writing results of 90,000 terminologies for electricity, communication and computer fields including smart grid terminologies, which are registered in the Open Korean Knowledge Dictionary, are shown. The system provides the capability of collection and delivery of academic society opinions for the selected and interpreted terminologies through the internet for standardization and industry propagation of smart grid terminologies.

  • 멀티미디어라는 단어는 이제 더 이상 낯선 용어가 아니며 일반에 널리 알려지고있다. 사람에 따라 그에 대한 개념이 약간씩 다르긴 하지만 그 차이는 미미하다. 이는 산업계에서도 마찬가지이다. 멀티미디어가 산업을 변화시키고 있다는 사실은 누구나 인정하고 있으며, 단지 업체별로 멀티미디어에 대한 대응 전략이 각 업체의 특성에 따라 차이를 보이고 있을 뿐이다. 다양한 정보처리를 지원하는 멀티미디어 OS는 현재 두가지 방향으로 발전하고 있는데, 그중 하나가 가정용 시장이다. 본 고는 일본의 니케이 일렉트로닉스지가 보도한 내용을 중심으로 멀티미디어 OS를 요약, 소개한 것으로, 가정 전기제품의 정보처리용으로 신영역을 개척하고 있는 멀티미디어 운영체계(OS)에 대해서 기술하고자 한다. 현재 가정용 멀티미디어 OS는 카레이다(Kaleida)사가 개발하고 있는 재생전용 멀티미디어 플레이 OS이고, 다른하나는 PC를 시장으로한 애플사의 퀵타임(Quick Time), 마이크로소프트사의 MME (MultiMedia Extension)와 IBM사의 MMPM/2 (MultiMedia Presentation Manager/2)가 그 주도권을 다투고 있다.

  • 삼성전자가 주최하는'삼성 4G포럼'이 지난 8월 27일과 28일 이틀 간 서울 신라호텔에서 개최됐다. 삼성 4G포럼은 2005년 모바일 와이맥스(와이브로) 기술을 세계 최초로 선보였고, 지난해에는 세계 유수의 경쟁업체들을 크게 앞서는 4G 기술을 선보임으로써 차세대 통신기술의 발전상을 꿰뚫어볼 수 있는 행사로 자리를 잡고 있다. 올해 행사에서는 삼성전자가 주도하는 모바일 와이맥스뿐만 아니라, 3GPP LTE(Long Term Evolution), 3GPP2 UMB(Ultra Mobile Broadband) 등 ITU가 4G의 유력 후보 기술로 꼽은 3대 통신기술이 한자리에서 소개되고 기술개발 및 표준화 동향을 공유하는 자리가 마련돼 더욱 눈길을 끌었다. 4세대 이동통신, 즉'4G'란 이동 중 100Mbps, 정지 상태에서는 1Gbps급 속도를 제공하는 무선 통신기술로, 지난 2005년 10월 ITU(국제전기통신연합)이'IMT-어드밴스트(advanced)'를 공식 명칭으로 결정한 바 있다. 하지만 현재의 3G와는 완전히 다른 새로운 세대의 통신 기술이라는 점을 강조하기 위해 여전히 4G라는 용어가 널리 쓰이고 있다.

  • 전 세계는 지구온난화와 고유가시대를 맞이하여 배출가스 규제에서 온실가스와 연비 규제로 확대되면서 그린카라는 새로운 용어가 등장하였다. 원유 고갈과 원전 불안으로 수송연료에도 신재생 에너지와 세일가스 등장에 큰 기대를 걸고 있으며, 새로운 에너지원을 사용하는 전기자동차와 수소연료전지 자동차의 개발도 활발이 진행되고 있으나 자동차시장의 형성은 각종 규제의 만족은 물론이고 경제성, 안전성, 편리성 등이 수반되어야 한다. 향후 세계 자동차시장은 에너지의 수급 사정과 시대의 요구 조건에 따라 크게 좌우되므로 각 국가별 여건을 고려하여 단계를 구분해서 그 시대에 가장 적합한 그린카 차종이 무엇인지를 신중하게 분석하여 산업화 정책을 추진해야 할 것이다. 이러한 관점에서 최근 기계연구원이 주축이 되어 개발하여 운행 중인 디젤하이브리드 자동차를 중심으로 세계 그린카 개발동향을 소개하고자 한다.
