  • WTO/TBT 협정에 따라 2006년부터 IEC 전선의 전면적인 사용과 전기설비기술기준의 판단기준에 IEC 60364 저압전기설비분야의 도입으로 국내현장에서 국제표준을 적용할 수 있게 되었다. 그러나 국제표준(IEC)은 내용이 포괄적이며, 원론적인 부분을 다루고 있어 실제 현장 적용에 많은 어려움이 있다. 이에 따라 대한전기협회에서는 국제표준(IEC)을 기초로 하여 국제수준과 대등한 "한국전기규정 KEC"를 제정중이며, 본 연구는 KS C IEC 60364-5-52 기초로 작성한 KEC 제2편 저압전기설비분야 제43장 배선설비의 제정현황을 소개하는 것이다.

  • This study analyzed how the subcontracting business relations and structures of cooperation affect the relationship skills (Outcome) that is divided into three steps. We analyzed integrated data every other year from 2005 to 2009. As a results, in the execution of technical cooperation trade relations have influenced the positive attributes, but recently their influence has been weakened. As for technical cooperation, the structure should alleviate the problem of the uneven performance of technical cooperation. We suggested that technical expertise and infrastructure make possible the culmination of the long-term technological competitiveness level.

  • The technical proposal suggested and published by MIC(Ministry of Information and Communication, henceforth MIC) contains too general assessment elements, which causes qualitative and subjective assessment of technical proposals. Thus, in terms of the technical proposal assessment. It lacks In fairness, validity and accuracy. Furthermore, it has a great deal of difficulty in assessment caused by the inconsistency between proposal planning and assessment methods. Also, each company has different writing format, so it is impossible to make use of its maneuvering data for the assessment. To overcome these weaknesses, our research focused on a quantitative evaluation on development organization, which is a part of organizational and administrative part of the technical proposal suggested and published by MIC. In this research, we divided development organization for the technical proposal into organization, teams, and team members, and then studied addition, deletion and merging for the assessment criteria. For the related study, we chose especially CMM(Capability Maturity Model) from a lot of international and national references, which is a model measuring the maturity of organization, and then we focused on Small-CMM which is available in the small-sized organization. We also suggested input form, description method, assessment elements for the quantitative assessment in the chosen developmental organization, and finally we proposed standard referencing criteria for the assessment. Our study concludes that our assessment method are valid and available in comparison with the previous Delphi method through a validity evaluation test.

  • This study analyzes the technical level and shows the priority technology for suspension bridges that play an iconic role as the country's landmark and contain an economic value. Analysis results show the technical level of suspension bridge is 82 percent compared to developed countries. In detail, the technical levels of 'materials', 'planning and design', and 'construction and maintenance' are 80.2 %, 81.7%, and 83.7% respectively. This study analyzes economic, social, technical importances and presents 'high-performance packaging material' as a priority technology.

  • ISO (International Organization for Standardization) is an independent, non-governmental international organization with a membership of 163 national standards bodies (NSB). The ISO standards are developed and processed within the technical committees (TC) or their subcommittees (SC) dealing with the different subject matters. The first technical committee, ISO/TC1, deals with screw threads and was created back in 1947. While, more recently, TC 309 was created to standardize organizational governance. The ISO technical committee in the field of metallic coatings was created in 1962 with the title ISO/TC107- Metallic and other inorganic coatings. This ISO/TC107 technical committee is dealing with the standardization of the characteristics of protective and decorative metallic coatings applied by electrolysis, fusion, vacuum or chemical means, mechanical deposition and ion plating. similarly, it also covers the standardization of the characteristics of protective and decorative non-metallic coatings (excluding paints and other organic coatings) on metal surface applied by electrolysis, fusion, vacuum or chemical means. Scope is further extended to the Standardization of the preparation of the substrates prior to the deposition of metallic and inorganic coatings. There are a total of 144 existing ISO standards published by this technical committee and has 19 participating countries (P-members) and 24 observing countries (O-members). Korean Agency for Technology and Standards (KATS), being the secretariat of ISO/TC107, is constantly supporting this technical committee for the development of standards and related activities.

  • In recent time there is vigorous requirement for the use of thick steel plate in various industrial fields including shipbuilding industry. Especially, with the continual increases in marine transportation volumes on a global scale, the steel of container ships has become thicker and thicker with the increased size of ships. In addition, the brittle crack arrestability of heavy thick plates was big issue, in recently. In this study, crack arrest test were conducted in order to investigate the crack arrestability of thick plates for shipbuilding steels, where test plate thicknesses were 50mm and 80mm. This paper introduces the brittle crack arrestability of heavy thick plates with thickness effect for shipbuilding.

  • The heating produced by the absorption of radiofrequency (RF) has been considered a secondary undesirable effect during MRI procedures. In this work, we have measured the power absorbed by distilled water, glycerol and egg-albumin during NMR and non-NMR experiments. The samples are dielectric and examples of different biological materials. The samples were irradiated using the same RF pulse sequence, whilst the magnetic field strength was the variable to be changed in the experiments. The measurements show a smooth increase of the thermal power as the magnetic field grows due to the magnetoresistive effect in the copper antenna, a coil around the probe, which is directly heating the sample. However, in the cases when the magnetic field was the adequate for the NMR to take place, some anomalies in the expected thermal powers were observed: the thermal power was higher in the cases of water and glycerol, and lower in the case of albumin. An ANOVA test demonstrated that the observed differences between the measured power and the expected power are significant.

  • While water management policies in Korea have focused on industrial water demand during the last decade, the amount of industrial water usage has decreased significantly. This paper estimates the technical efficiency of industrial water in order to test whether the reduction of industrial water usage is a result of improving the level of technical efficiency of industrial water. This paper shows that the technical efficiency of industrial water use slightly decreased from 0.5183 in 1998 to 0.4853 in 2003. In addition, these estimates are much less than those of other inputs and so, there is still much room for reducing the amount of industrial water use through improving technical efficiency even though the average productivity of industrial water has improved during this period.
