Countries around the world have already taken direct and indirect measures to warn of the harmful effects of mobile phone electromagnetic waves. On the other hand, in the Republic of Korea the installation of Wi-Fi has been expandedwithout restrictions by location, and there is a widespread atmosphere of protesting human rights violations even if young students cannot use mobile phones, ignoring problems caused by the use of mobile phones. Human brain cells are increasingly exposed to electromagnetic waves of mobile phones as the penetration rate of smartphones grows.In order to solve the long-lasting question of whether electromagnetic waves from mobile phones will harm the human body, many studies are being conducted in various countries around the world, andthe recently published findingshave warned of the potential for harm. The labeling of electromagnetic waves alone is not sufficient to raise awareness about the dangers of electromagnetic waves. It is necessary that the Republic of Korea organize and operate a national electromagnetic wave research center in line with its status as an IT powerhouse, along with the revision of the Radio Wave Act, which directly warns the public about the hazards of mobile phone electromagnetic waves and can directly impose obligations on the mobile phone industry.

This study focuses on Korea's traditional-style soryebok, in terms of its foundation, progression, and structural features. The research methods employed here include literature analyses of relevant laws and an official daily gazette, and practical analyses of artifacts and photographic documents. Especially, the artifacts of heukdannyeong(black uniform for officials with a round neck) in the form of chaksu(tight sleeves) were examined, which was regulated as soryebok in Eulmiuijegaehyeok. The term "soryebok" firstly appeared in "使和記略"(Sahwagiryak) written by Park Yeong-hyo, a foreign envoy to Japan, in 1882. Emperor's invitation written in the book asked him to wear daeryebok at the ritual and soryebok to the banquet. Soryebok was not adopted in Gapshinuijegaehyeok in 1884. However, several illustrated documents of the modern banquets at that time reveal that sabok, which was included in the 1884 reform, was used as soryebok. According to the Gapouijegaehyeok in December 1894, courtiers were required to wear heukdannyeong as daeryebok, and add juui(topcoat) and dapho(sleeveless coat) as tongsangyebok when they visited the royal palace. In Joseon's first daeryebok system, the term "tongsangyebok" that had been used in Japan was employed before soryebok was used. According to Eulmiuijegaehyeok in August 1895, the term "soryebok" originated from a costume ritual for courtiers of the Joseon Dynasty. Soryebok featured heokbannyeong chaksupo, samo (winged hat for officials), sokdae(belt), and hwaja (shoes for officials). There are around 24 artifact pieces of heukdannyeong in the form of chaksu(tight sleeves) in the following locations: garments of Prince Heungwangun and Wansungun, the court artifacts, Korea University Museum, Yun Ung-ryeol's family housed at Yonsei University, and Kyungwoon Museum. Artifacts have mu(godet) pulled back and a topcoat-like triangular mu. In conclusion, heukdannyeong, traditional-style soryebok has significance in the history of modern dress because streamlined traditional clothes and newly introduced Western dress system were able to be combined.

An apartment house and an officetel are already our most important residential space generally. Among food, clothing and shelter, an apartment and an officetel are in charge of a shelter as the most fundamental in our life. To live in an apartment and an officetel, it is necessory for residents to write a lot of informations about themselves. Therefore massive privacy files about apartment's residents is inevitable and it is managing in its own way. A privacy accident in an apartment houses would be a big society problem. This study examined 'tenant list' to find out what it collects and what it's problems are and proposed some vairous measures about the privacy improvements like items reduction & consent process improvement in an apartment house and an officetel from privacy laws perspective.

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.

The U-City comprehensive plan has been settled on November in 2009 by U-City law which was enacted in 2008. On this, the U-City plan's framework which local governments established has been set. However, those who work for U-City in local governments and private sector would be fallen into confusion because they have not fully understood yet the concept of planning system in the U-City plan. In this condition of the early stage, some problems that are overlapping investments and lack of coordination between plans may occur. On this background, it is needed to understand the U-City plan's status and role by figuring out the relationship between U-City plan and other related plans. The goal of this paper is to suggest implications that are differences and similarities for coordination among the plans through a comparison with detailed instructions and laws related to U-City planning.
