  • Electric motors and drives consume the largest amount of electricity more than 40% of global electricity consumption. In addition, motors, drives and its components are included in the global high-trade products and the main driving source for industrial equipment and house appliances. Thus, International standards and regulations for their safety and efficiency are internationally being discussed and created for the protection of its citizens and energy saving. So, understanding the international standards and the regulation of each country is essential to enhance overseas market and to develop product. In this paper, on the basis of this background, status and trends of international standards and regulations are introduced for safety and efficiency of motors and the drives. Safety and efficiency of the IEC (International Electrotechical Commission) standards are introduced in the emphasis. Also, regulations are studied about the differences and trends in each county.

  • In this paper, we studied electrical characteristics of internal converter type of LED lamps for road and street lighting. We surveyed electro-technical regulations and KS(Korean industrial standards) about LED luminairs. Waveforms of voltage and current, thermal distributions, insulation resistances between live parts and exposed conductive parts, and flame test of cover of LED lamps were experimented and analyzed. In regulations, insulation resistance between live conductors and exposed conductive parts should be greater than $0.2M{\Omega}$ in case nominal voltage of wiring is 220V. In KS codes, the value of insulation resistance should be greater than $2M{\Omega}$ while applying DC 500V or DC 100V. In the result of this study, waveforms of primary voltage and current were distorted. There was difference in waveforms of secondary voltage and current according to composition of converter. Mostly, insulation resistances were measured high more than regulation and code value but some measured points were measured badly($0.0M{\Omega}$). Cover of LED lamps was ignited easily. We expect that the results of this study would be helpful for revision of regulations and national codes for the electrical safety of LED road and street lighting.

  • As Decentralized Generation(DG) becomes more reliable and economically feasible, it is expected that a higher application of DG units would be interconnected to the existing grids. This new market penetration of DG technologies is linked to a large number of factors like technologies costs and performances, interconnection issues, safety, market regulations, environmental issues or grid connection constrains. This paper describes the procedures and results for the mechanical, electrical, and environmental tests of MGT on actual grid-connection under Korean regulations. As one of the achievements, the simulation model of MGT was developed, so that it will be able to analyze or propose new distributed generation system using MGT. The field test was conducted in order to respond to a wide variety of needs for noise reduction and utilization and its performance was evaluated in consideration of its operational problems. The MGT is successfully supplying electricity to Korean grids with satisfying various regulations. The suggested strategy and experience for the evaluation of the distributed generation will be used for the introduction of other distributed generation technologies into the grid in the future.

  • Respirator fit testing is required before entering specific work environmentals to ensure that the respirator worn satisfies a minimum of fit and that the user knows when the respirator fits properly. The fit of a respirator can be determined by qualitative (QLFT) or quantitative fit test (QNFT). The QNFT, having been universally accepted more than the QLFT, provide an objective and numerical basis by measuring a fit factor (FF). Until a few years age, only one QNFT technigue was available and accepted by U.S. Occupational Safety and Health Administration (OSHA) regulations. In the 1980's and 1990's, several new and fundamentally different QNFT methods were developed. Two of the newer methods are commercially availale and are accepted by OSHA as suitable alternatives. In this articles, the principle of operation of each ONFT technique is explained and each technique's major advantages and disadvantages are pointed out. Emphasis is given to negative-pressure air-purifying respirators, as they are in most frequent use today. The requirements and recommendations for fit testing positive-pressure respirators are discussed as well. Finally, the presently available QNFT standards and regulations are summarized to assist the user in making fit testing decisions.

  • Objectives: The present system of occupational safety and health law gives priority to traditional command and control regulations. However, this may give rise to problems such as the delay of standard-setting and shortages of human resources. The aim of this study is to examine the usability of private standards in occupational safety and health systems. Materials: After the limits of occupational safety and health law were examined, an application plan for private norms (EN, as enforced in the EU) and occupational safety and health management systems (OSHMS) was investigated. Results: The utilization of private norms and OSHMS may address the limits of the current legal system. In particular, OSHMS is known internationally as a measure for achieving improvements in overall occupational safety and health performance. As a result, occupational safety and health law and private norms/OSHMS are complementary to one another. Conclusions: Even though the utilization of private standards may give rise to legal questions, such standards as complementary measures to traditional command and control regulations need to be utilized progressively in occupational safety and health systems.

  • This study examined the characteristics of the royal progress and regulations on costumes in the king's excursion by a royal carriage and then investigates King Gojong's costumes in "Dongga Painting of the Korean Empire". To examine the regulations on costumes in the king's excursion by a royal carriage, there are unique costumes, 'Ikseongwan and Gangsapo' for the great memorial service for ancestors during the Korean Empire period. 'Ikseongwan and Gangsapo' are not provided in the code during the Joseon Dynasty period. Thus, it was not provided in the regulations, in the actual execution of the ritual, the king put on 'Ikseongwan and Gangsapo,' so entering the Korean Empire period, it was legislated as 'Ikseon-gwanbok' in Daehan-yejeon. There is a scene in the "Dongga Painting of the Korean Empire" in which the king pays a visit on Yeon, holding 'Gyu' in 'Ikseongwan and Gonryongpo'. However, holding 'Gyu' on Yeon in 'Ikseongwan and Gonryongpo' can be seen in King Gojong's royal procession to hold Jongmyo Chunhyangdaeje in the year of Gabo (1894). This study showed that there was a compromise for the ritual despite not being regulated by law.

  • Mandatory shutdown policy of the juvenile protection act was enforced in December 2011 to prevent game addiction of the youth. However, the size of game market in Korea seems to be reduced significantly after implementation of the shutdown policy. The purpose of this study is to investigate the impact of current government regulations on Korean online game market. Based on empirical evidences and results from the related literature, we developed several causal loop diagrams(CLD) and system dynamics models. The CLD include sub-diagrams of innovation processes, user commitments, and operational costs. We conducted simulation analyses under various policy scenarios, adopting Normalized Unit Modelling By Elementary Relationship(NUMBER). Our results show that first, the impact of time regulation on the number of users is greater than the impact of content regulation. Second, the quality of domestic online game appears more elastic to regulations than the quality of foreign online game. The results of this study suggest that the deregulation in Korean online game market can narrow the gap in market outcomes between domestic and foreign online games. Some recommendations for future study are suggested.

  • We review the research literature on relationship between environmental regulation and industrial development in three aspects of environmental regulation and investment, environmental regulation and efficiency, environmental regulation and trade. Indeed, the linkage between environmental regulation and material consumption of industrial system is absent. Environmental regulation is measured as the expenditure share for industrial pollutants abatement, and effluent charge intensity. Using panel-level data from 31 provinces, municipalities and autonomous regions in China, we build correlation models between material consumption and environmental regulation, results show that: (1) there are significant quadratic function relationship between material consumption and environmental regulation. And there is the fact that inflection point exists. (2) On basis of inflection points, we make two remarkable reflections. Firstly, the inflection points are the most important scale to judge reasonability and performance of regulations. Secondly, a Pareto improvement may occur when the regulations achieve a certain target. (3) Both intensities of industrial pollutants abatement expenditure and effluent charge have not yet achieved the expected target in most regions of mainland China at present. And most of regions of material consumption decreasing are distributed in western China. Main reasons lie in the impacts of industrial features as well as the regulations.

  • To produce well-qualified medical doctors, clinical training is a crucial part of medical education. To this end, teaching hospitals should be carefully selected and professionally managed. However, in Korea, there are no regulations or standards for training hospitals. Instead, some of the regulations that target teaching interns and residents are applied to teaching hospitals. In this study, we reviewed standards and regulations for training hospitals in other countries as a basis for proposing new standards for teaching hospitals in Korea. These new standards take into account the current environment of Korean medicine with the aim of designing appropriate educational programs for students and professional development systems for professors as well as providing educational resources and addressing the local community and international exchange opportunities.
