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.

Research on RSS(Really Simple Syndication) based application and services are being deployed both domestically and internationally. The RSS service in the area of science and technology should be flexible to the various sources of information as well as the various platform and environments that they are being serviced. It also requires a standardized system to meet the above needs. We have analyzed the use of RSS services overseas as well as domestic services to suggest the implementation of standard system for the syndication of science and technology information based on RSS.

The technical data for transmission line design and maintenance are calculated by a very complicated numerical formula so it is almost impossible to solve them by hand. Therefore the TOWER+ EXPERT SYSTEM was developed to systematically support technical data for transmission line design and maintenance. This system is able to calculate technical data which is applied to all conductors in our county, - that is 12 kinds of systems with 86 numbers of standard conductors, - and is programed to be user friendly by adopting dialogue windows, menu selection functions. Moreover, it minimizes input data by automatically providing standard transmission line design data, and it includes guidance of applicable work, program usage, data input process, help, explanation of terms and automatic error recovery functions that even a beginner can easily use.

Method of remodeling builder selection for remodeling is competitive bidding. also metropolitan city, megalopolis city, city more than 50million have to do basic plan for remodeling before establishment of a housing cooperative. Purpose of basic plan is improvement of living conditions & the Quality of Life for resident. Technical Proposal Tendering in spite of being the a reasonable bidding system, institutional part, appraisal standard and the item part, consider procedure pard is performed in a similar way to the existing bidding system. so, technical proposal tendering is appropriate for future Method of builder selection of remodeling. therefore, the study purpose is a evaluation element of technical proposal tendering for apartment remodeling business The methods of study is understanding concept through review of precedent literature. Next, case investigation through Analysis of focal points. Lastly, evaluation element deduction of technical proposal tendering for apartment remodeling business through specialist conversation. As a result, Alteration of a right & move management is added to evaluation element's professional field. And detail item is alteration of a right & move management.

The problem should be approached in terms of recovering essential functions of technical high school and identification to supply stable and quality human resources in technical sector. An adequate space programming for technical high school is needed to educate effective skills and techniques. Considering the education directions of vocational high school, the article covers principals of technical school's construction plan and directions and, based on this, suggest the way of estimating the scale in construction plan of technical school. Through this research, systematic and reasonable space planning can be possible. The range of this research is based on development directions of society and education and an objective standard in a newly reformed the 7th Stage of Education. In addition, the research is limited to technical high school among kinds of vocational high school. The purpose is to redefine the role of technical school that face identification crisis currently, comparing to the past, and to suggest a more effective space planning. The research limits the space to classes for specialized subjects, a core space for education in technical school among diverse spaces.

In order to overcome the drawbacks of low rated power of the string inverter, the necessity of micro -inverters and future development directions will be examined by comparing the power conditioner system with existing PCS using micro inverter. Currently, string inverters have been used in household solar power generation systems, and research and penetration of micro-inverters(PV-MIC) have been expanding, which can overcome the shortcomings of string inverters starting from Europe. However, in the PV inverter industry, precise technical standards, test measurement equipment and related test methods for micro-inverters(PV-MIC) are obstacles to product development. Therefore, in this paper, considering the characteristics of micro-inverter (PV-MIC), it aims to make it competitive so that it does not lag behind advanced technology change through test measurement equipment and related technical standard.

The study aims to supplement facility management plan and safety regulations & standard of oil pipeline by searching and reviewing related regulation & standard inside and outside of the country. Korean regulation & standard is reviewed based on harbor and fishery design standard of the ministry of maritime affairs and fisheries, general technology standard of oil pipeline safety regulation, gas excavation construction and safety maintenance indicator of Korea gas corporation. Global regulation & standard is reviewed based on U.S standard inspection for offshore pipeline and Europe/Mexico standard inspection for offshore pipeline. The contents of offshore pipeline installation is inserted into pipeline sector for objected facilities of safety inspection regulation & standard and, the standard of safety inspection for offshore pipeline is newly presented into pipeline maintenance part of the planning facilities management with its inspection period and method.

In Article 311 of the Regulation on Occupational Safety and Health Standards requires the use of Korean Industrial Standards Act in accordance with the Industrial Standardization Act. However, the classification, inspection, maintenance, design, selection, and installation of explosion hazard locations for explosion and explosion prevention and internalization of 'safety' in the performance maintenance phase of electrical machinery and equipment There is no technical and institutional management plan for remodeling and alteration. Analysis of actual conditions and problems related to the installation, use, and maintenance of explosion-proof equipment, comparative analysis of domestic and international technical standards and systems, technical, institutional and administrative systems and systems related to installation, use, and maintenance of explosion-proof equipment, technical personnel and qualifications, etc. It is to propose legislation, system improvement, and technical standard establishment related to the maintenance of explosion-proof facility performance through improvement of the necessity and feasibility study for establishment of the legal status of the management site and management plan. As technical measures, KS standard revision (draft), KOSHA guide (draft) and explosion-proof facility performance maintenance manual were presented. In addition, the institutional management plan proposed the revised rule on occupational safety and health standards, the revised rule on the restriction of employment of hazardous work, and the manpower training program related to the maintenance of explosion-proof facilities and the qualification plan. Enhance safety at the installation, use, and maintenance stage of explosion-proof structured electrical machinery. It is expected to be used to classify explosion hazards, select related equipment, and to update and standardize standards related to installation, use and maintenance.
