  • Fuel cell systems are a completely different form of electricity source that has been used so far and is an aggregation of multiple technologies with multidisciplinary features that can be operated safely only when gas and electrical safety are being considered. Since fuel cells generate through electrochemical reactions there are difficulties in ensuring electricity safety, power quality assessment, effective control and reliability standards for system faults using conventional inspection techniques and even though they are necessary as a primary means for reduction of CO2 owing to the Climate Convention, electrical safety assessment and measures are required for the prevention of faults in residential facilities. Although small-scaled distributed power supplies can be utilized as important means of peak control and energy management measures, research is required for observing the effects on the system and the development of inspection technology to ensure stable operation, and the electrical safety of residential fuel cell systems need to be assessed and the problems derived for establishing electrical safety standards. From the year 2002, Japan has established laws on technical safety standards and development and rules on the product specifications and standards for the industrialization of hydrogen fuel cells. Also, a lot of effort have been made for the commercialization of fuel cells by building one-stop certification services. Internationally, the IEC TC 105 has established international standards based on fuel cells. In order to protect the national interest, the country should be able to respond accordingly meet global standards. In fact, in Korea, to comply with the international trend, Korea Energy Management Corporation is establishing a certified agenda for fuel cells and Korean Agency for Technology and Standards is enacting technical standards for fuel cells. The current terms of fuel cells are that research has been focused more on the quality and performance of manufactured products rather than stable power operation and maintenance over time. In this paper, by considering the household fuel cell as a power device, the safety standards of the fuel cell system for a reliable operation with the existing power system is being proposed.

  • A longitudinal study traced changes in students' understanding of Nature Of science (NOS) through the public secondary science education in Ontario Canada. Although the concepts of NOS are complicated, and students' understandings are not easy to change, not many longitudinal studies have been done across the world. The current study tried to identify the changes of participating students' understandings of NOS for two and half years of public secondary science education in Ontario Canada. Pretest was administered using Views of Nature of Science (VNOS-C) when six participants graduated from a middle school of Toronto. Two and half years of secondary education, the posttest was carried out using the same instrument. After pre and posttest, probing interviews were performed. The analysis of the data was founded on the Standards and the conceptual framework for this study. The findings were that the initial views have little changed. Most examples and explanations the participants provided were from their science classes. Lab activities for confirming the existing laws and theories and observable photos in science textbooks made students regard the knowledge as a truth. Naturally, their knowledge has been expanded for 2 and 1/2 years, but this expansion of scientific knowledge led students toward Universalist views on science. On the other hand, when science was presented with a historical approach or was networked with other concepts, students acknowledged science and scientific knowledge had been induced from inferences as well as observations and experimental results. Based on the findings the authors of this research suggest that educating the knowledge of science should be historical and networked approaches rather than teaching the knowledge as concise and true statements of the nature.

  • The purpose of this study is to analyze green growth issues such as employment, education and training, social capital and nature's standing right from the complementary perspective between natural environment conservation and economic growth. Green growth can be defined as a growth which lowers an increasing rate of entropy and at the same time improves our living standard. Green growth paradigm requires a quite amount of understanding the laws of thermodynamics and the uncertainty principle as the highest orders which regulate our overall socio-economic behaviors. They suggest that socio-economic growth is a mere transformation process of natural energy from one form to another and they increases natural manmade entropy over time. The most important issue of green growth policy may be a problem concerning employment and/or unemployment since green growth may induce inevitable movement of resources from the existing industries to the green sector. In particular, green industries will demand more highly specialized manpower than the existing ones. Without a well-designed new training education system and social capital accumulation toward environmental concerns, green growth may accompany a substantial amount of structural involuntary frictional unemployment. This may increase not only wealth-distribution disparity but also political instability. In order to achieve harmonious green growth, we should recognize that there are important complementary relationships between green and growth. Our society should also be able to innovate the existing educational system to accumulate social capital, to create a new sharing system, and to admit nature's standing right. Although the 2003 lawsuit case of Korean Salamander in Cheonseong Mountain went against plaintiff, it would provide apparently our society with a way of green development ahead.

  • Japanese welfare legislation for the disabled was enacted via Law 283 on December 26. 1956. The push for such legislation at the national level had gown concurrent with development of Japan's post-war economy Korean welfare law for disabled was made 22 years later and was again amended in 1989. The current legislation promotes and supports the legal welfare of the Koran disabled. The following are the results of a comparison between Korean and Japanese accessibility facilities and welfare law; 1) Japan's developement of disabled people's welfare law is inextricably linked to the development of disabled people's advocacy and the human rights movement. In addition, welfare policy has shifts its mandate from rehabilitation to independent living. It follows that local altitudes will play a pivotal role in further policy initiatives. Korean disabled people's welfare policy emerged hand in hand with economic recovery and development following the Korean War. By 1977 a special education law was enacted which-like it Japanese counterpart-promoted the education of disabled children. 2) Accessibility facilities were developed privately movement. The disabled faced constant and systematic disadvantages in public/private buildings and transportation systems. A general lack of cultural awareness and information relating ti these problems prevailed. These included-hut were by no means limited to sign language (for hearing the impaired) and braille(the language of blind). However, new attitudes and improvements have since emerged and new laws have resulted in the publication of Korean 'White Book' outlining the everyday problems faced by the disabled. In addition, mort convenient access facilities have been constructed in public and private buildings. In closing, legal support for the disabled, senior citizens and pregnant women continues to be improved by newer legislation enacted tin April 6, 1977.

  • The International Chamber of Commerce published the millennium edition of its standard trade definitions, Incoterms 2000. Incoterms are a basic reference for sales contracts, in constant daily use throughout the world. The new version will make it easier for traders to do business in the new century, despite the growing volume and complexity of international transactions. Since Incoterms were first published in 1936, they have been updated six times. They precisely define the responsibilities of buyer and seller and are recognized as the international standard by customs authorities and courts in all the main trading nations. It is important for traders to incorporate the correct Incoterms into their international contracts to avoid unnecessary legal problems. Courts may otherwise interpret trade terms according to often widely divergent national laws and unless the use of Incoterms is specified, expensive legal disputes can arise. Division of costs is a most important element in every contract of sale. The parties must know not only who does what but also how costs resulting therefrom should be divided between them. In most cases the fact that a party must do something means that he must also bear the resulting costs, unless otherwise agreed. But there are many exceptions to this principle and uncertainties arise, particularly with respect to services performed by other parties. Also, difficulties arise with respect to the division of costs whenever additional costs are caused by unexpected events, such as hindrances causing a ship to deviate or to remain in a seaport longer than expected. The main principle of the division of costs is clear enough: the seller has to pay costs necessary for the goods to reach the agreed point of delivery, and the buyer has to pay any further costs after that point. But as noted, it is not always easy to implement this principle in practice, since the detailed distribution of functions under the various trade terms is not and cannot be fully defined in Incoterms. Instead, failing precise stipulations in the contract of sale, guidance must be sought from other criteria such as commercial practices used earlier by the same parties or the custom of trade.

  • We are concerned about how to apply the theories of oriental medicine appropriately, which direction should it be taken, and how it should be developed. And it is believed to be essential for the government to make efforts to set a standard and laws to validate the medicinal effects and process of the assessment so that the systematic development can be encouraged, and to prepare guidance for the food development for national health improvement Ihis study was peformed to provide basic data that predict the usefulness of oriental medicinal herbs to remove the dampness through diuresis for excess syndrome obesity with oriental diet therapy cuisine(Yak-Sun). Five oriental medicininal herbs, Coix lachryma-jobi L, Atractylodes lancea DC., Ligusticum wallichii F., Angelica sinensis D., Zingiber officinale R. were collected and made into mixing extracts(OMCE). And we examined the effects of OMCE on body weight serum glucose, insulin and lipid profile improvement in rats fed high fat diets. Sprague-Dawley rae(230-250 g) were randomly divided into five groups : basal diet(normal diet control group, NCG), only high fat diet(High fat control group, HCG), high fat diet and supplemented with 25mg/100g body weight 50mg/100g body weight 75mg/100g body weight by OMCE(HLG, HMG, HHG). These experimental diets were fed for 6 weeks. The OME fed groups decreased more significantly in weight serum glucose insulin and lipids than the high fat control group did. These results imply that the OMCE can be used as a safe and clinically applicable ingredients for diet called Yaksun of excess syndrome obesity in human.
