도토리의 항산화 효능을 평가하기 위해 선충을 실험동물로 사용하여 생체 내 산화성 스트레스에 대한 저항성을 평가하였다. 배양배지에 50, 100, 500, 1,000 mg/L 농도의 도토리 분말 수용액을 첨가하여 산화성 스트레스 하에서의 생존률을 비교한 결과, 500 mg/L의 농도에서 유의적인 생존률 증가를 관찰할 수 있었다. 그 다음 위의 생체 내 항산화 효능 농도에서 도토리 분말 수용액이 개체의 수명에 미치는 영향을 측정하였다. 그 결과 도토리 분말 수용액을 첨가한 배양배지에서 키운 선충이 대조군에 비해 유의적으로 증가된 평균 수명과 최대 수명을 가지는 것을 관찰하였다. 이는 도토리 분말 수용액이 생체 내에서 항산화 효능을 발휘하여 노화에 따른 세포 내 물질의 산화적 손상을 완화시키고, 그로 인해 개체의 수명 연장까지 일으킨 것으로 사료된다. 또한 번식률 변화를 관찰한 결과, 도토리 분말 수용액은 개체의 번식률에는 영향을 미치지 않는 것으로 나타났다. 이는 기존의 많은 수명 연장 표현형을 보이는 돌연변이 선충들에서의 결과와는 상반되는 것으로, 도토리 분말 수용액의 경우에는 번식력 감소를 수반하지 않고서도 수명 연장이 가능하다는 것을 보여준다. 본 연구의 결과는 향후 도토리를 이용한 항산화, 항노화 기능성 식품 개발과 같은 응용 연구 분야와 도토리의 생체 기능성과 관련 기전 연구와 같은 기초 연구 분야에도 널리 활용될 것으로 사료된다.

As Korea has reached a free trade agreement with the United States of America, it is required to provide an appropriate procedure to ".kr" domain name disputes based on the principles established in the Uniform Domain Name Dispute Resolution Policy(UDRP). Currently, Internet address Dispute Resolution Committee(IDRC) established under Article 16 of the Act on Internet Address Resources provides the dispute resolution proceedings to resolve ".kr" domain name disputes. While the IDRC's proceeding is similar to the UDRP administrative proceeding in procedural aspects, the Domain Name Dispute Mediation Policy that is established by the IDRC and that applies to disputes involving ".kr" domain names is very different from the UDRP for generic Top Level Domain (gTLD) in substantial aspects. Under the Korea-U.S. Free Trade Agreement(KORUS FTA), it is expected that either the Domain Name Dispute Mediation Policy to be amended to adopt the UDRP or the IDRC to examine the Domain Name Dispute Mediation Policy in order to harmonize it with the principles established in the UDRP. It is a common practice of cybersquatters to warehouse a number of domain names without any active use of these domain names after their registration. The Domain Name Dispute Mediation Policy provides that the complainant may request to transfer or delete the registration of the disputed domain name if the registrant registered, holds or uses the disputed domain name in bad faith. This provision lifts the complainant's burden of proof to show the respondent's bad faith because the complainant is only required to prove one of the three bad faiths which are registration in bad faith, holding in bad faith, or use in bad faith. The aforementioned resolution procedure is different from the UDRP regime which requires the complainant, in compliance with paragraph 4(b) of the UDRP, to prove that the disputed domain name has been registered in bad faith and is being used in bad faith. Therefore, the complainant carries heavy burden of proof under the UDRP. The IDRC should deny the complaint if the respondent has legitimate rights or interests in the domain names. Under the UDRP, the complainant must show that the respondent has no rights or legitimate interests in the disputed domain name. The UDRP sets out three illustrative circumstances, any one of which if proved by the respondent, shall be evidence of the respondent's rights to or legitimate interests in the domain name. As the Domain Name Dispute Mediation Policy provides only a general provision regarding the respondent's legitimate rights or interests, the respondent can be placed in a very week foundation to be protected under the Policy. It is therefore recommended for the IDRC to adopt the three UDRP circumstances to guide how the respondent can demonstrate his/her legitimate rights or interests in the disputed domain name. In accordance with the KORUS FTA, the Korean Government is required to provide online publication to a reliable and accurate database of contact information concerning domain name registrants. Cybersquatters often provide inaccurate contact information or willfully conceal their identity to avoid objection by trademark owners. It may cause unnecessary and unwarranted delay of the administrative proceedings. The respondent may loss the opportunity to assert his/her rights or legitimate interests in the domain name due to inability to submit the response effectively and timely. The respondent could breach a registration agreement with a registrar which requires the registrant to submit and update accurate contact information. The respondent who is reluctant to disclose his/her contact information on the Internet citing for privacy rights and protection. This is however debatable as the respondent may use the proxy registration service provided by the registrar to protect the respondent's privacy.

At its thirty-second session in 1999, the UNCITRAL had before it the requested note entitled "Possible future work in the area of international commercial arbitration." After concluding the discussion on its future work in the area of international commercial arbitration, it was agreed that the priority items for the working group should be conciliation, requirement of written form for the arbitration and enforceability of interim measures of protection. the Commission entrusted the work to the Working Group on Arbitration which held its thirty-second session at Vienna from 20 to 31 March 2000. The Working Group discussed agenda item 3 on the basis of the report of Secretary General entitled "Possible uniform rules on certain issues concerning settlement of commercial disputes : conciliation, interim measures of protection, written form for arbitration agreement." At its thirty-three session in 2000, the UNCITRAL had before it the report of Secretary General on agenda item 3 discussed by the Working Group. The Working Group discussed the issues relating to certain aspects of conciliation proceedings ; (1) Admissibility of certain evidence in subsequent judicial or arbitral proceedings ; (2) Role of conciliatior in arbitration or court proceedings ; (3) Enforceability of settlement agreements reached in conciliation proceedings ; (4) Other possible items for harmonized treatment : a) Admissibility or desirability of conciliation by arbitrators b) Effect of an agreement to conciliate on judicial or arbitral proceedings c) Effect of conciliation on the running of limitation period d) Communication between the conciliator and parties ; disclosure of information e) Role of conciliator. It was generally considered that decisions as to the form of the text to be prepared should be made at a later stage when the substance of prepared solutions would become clearer. However, it was noted that model legislative provisions seemed to be appropriate form for a number of matters proposed to be discussed in the area conciliation. There was general support in the Working Group for the proposition to perpare a legislative regime governing the enforcement of interim measures of protection ordered by arbitral tribunals. It was generally considered that legislative regime should apply to enforcement of interim measures issued in arbitration taking place in State where enforcement was sought as well as outside that State. It was generally observed that there was a need for provisions which conformed to current practice in international trade with regard to requirements of written form for arbitration agreement. The view was adopted by the Working Group that the objective of ensuring a uniform interpretation of the form requirement that responded to the needs of international trade could be achieved by : preparing a model legislative provision clarifying, for avoidance of doubt, the scope of article 7(2) of the UNCITRAL Model Law on International Commercial Arbitration : and adopting a declaration, resolution or statement addressing the interpretation of the New York Convention that would reflect a broad understanding of the form requirement. There was general agreement in the Working Group that, in order to promote the use of electronic commerce for international trade and leave the parties free to agree to the use of arbitration in the electronic commerce sphere, article II(2) of the New York Convention should be interpreted to cover the use of electronic means of communication as defined un article 2 of the Model Law on Electronic Commerce and that it required no amendment to do that. The UNCITRAL may wish to consider to the desirability of preparing uniform provisions on any of those issues concerning conciliation and arbitration proceedings, possibly indicating whether future work should be towards a legislative text or non-legislative text.

재판매가격유지(再版賣價格維持)는 어떤 다른 제품보다도 도서유통(圖書流通)에서 가장 오랫동안 쓰여 왔으며, 원칙적으로 재판매가격유지를 금지하고 있는 우리의 "독점규제(獨占規制) 및 공정거래(公正去來)에 관(關)한 법률(法律)"에서도 출판물(出版物) 등 저작물(著作物)에 대해서만은 이를 예외적으로 허용하고 있다. 본고(本稿)는 도서유통에서의 재판매가격유지(再版賣價格維持)와 반품제(返品制)의 경제적(經濟的) 기능(機能)과 효과(效果)를 분석하고 있다. 재판매가격유지는 서점(書店)이 수집 전달하는 시장정보(市場情報)에 대한 재산권(財産權)을 확립하여 판매전망이 불확실한 도서가 취급 전시되도록 하는 것으로 반품제(返品制)가 이와 동일한 경제적 기능을 제공하는 대체적(大替的) 수단(手段)이 된다. 미국에서 재판매가격유지(再版賣價格維持)가 위법화(違法化)되자 반품제(返品制)가 도입되었고 판매마진이 감소하면서 반품율(返品率)이 증가한 것이나, 재판매가격유지를 허용해 온 영국 등 유럽제국에서 반품제 없이 도서유통(圖書流通)이 이루어지고 있는 것이 이를 뒷받침해 준다. 도서(圖書)의 재판매가격유지(再版賣價格維持) 허용으로 출판사들은 반품(返品)에 따른 비용(費用)을 감소시킬 수 있고 서점들이 대형화(大型化) 유인(誘引)을 갖게 될 것이다. 그러나 재판매가격유지계약(再版賣價格維持契約)을 체결한 출판사가 많지 않다는 것은 이미 반품제(返品制)가 광범위하게 쓰이고 있는 현실을 반영하는 것으로 재판매가격유지는 출판사가 원하는 도서에 대해서만 허용되어야 하며 할인판매여부(割引販賣與否)와 시기(時期)도 출판사가 제한없이 결정할 수 있도록 하여야 할 것이다.

From the ancient times, incense was used for various usages including a means of beauty expression with flavor, a medicine for disease treatment and a device for religious event or ritual. The period of T'ang was the times when cultural and material exchanges with foreign countries were very actively made under the political openness of the Chinese nation. Here the exchanges were made mainly through inland trade, called Silk Road(絲綢之路) and marine trade routes, Incense Road(香料之路). This indicates that incense was one of the main items actively traded at that time. In addition, literatures of the T'ang period show that in the Chinese nation, a wide range of classes from the imperial family to the public used incense for many different purposes. This suggests that the culture of incense was deeply prevailed and very socially significant in T'ang. This study investigated social factors that promoted the incense culture of T'ang and the applications and types of incense widely used in the period of T'ang. First, influential religions and the openness of sex culture were main social factors that made incense culture flourish in the period of T'ang. Above all, two main religions of the Chinese nation, Buddhism and Taoism became secularized under political protection by the imperial family. As Buddhism was popularized, the Buddhist ritual of incense burning made a contribution to making public incense culture. Providing its doctrines of eternal youth and eternal life, Taoism necessarily used incense to form a Taoistic climate. The flourishment of the foresaid religion in T'ang added more fuel to that of incense culture in the Chinese nation. The openness of sex culture brought about the Inauguration of the empress, improvement in female position and free relationships between man and woman. It was accelerated by sexology as a method of eternal youth provided by Taoism. The opened culture also developed the culture of kibang where female entertainers called kinyeo consumed lots of incense for decoration and sexual desire stimulation. These open climates of T'ang society made a great contribution to making incense culture, especially for decoration, prevailed throughout the Chinese nation. Second, types of incense prevailed and widely used in the period of T'ang included olive incense, germander(廣藿香), olibnum(乳香), myrrh Resinoid(沒藥), jia Xiang(甲香), clove(丁香) and Shen xian(沈香), all of which were imported from foreign nations and had various applications. Specifically, olive incense, germander(廣藿香), olibnum(乳香) and myrrh Resinoid(沒藥) were used for religious purposes while, jia Xiang(甲香), clove(丁香) and Shen xian(沈香) for the purposes of religion and decoration. In conclusion, a number of social factors including political, religious and medical purposes and the openness of sex culture set fundamentals on which the culture of incense was extensively developed and established as a social trend in T'ang. In the Chinese nation, incense culture was not just an option for taste, but a part of life style social members needed to know. People of T'ang not only enjoyed incense mainly for purposes of religion, pleasure and make-up, but also had the wisdom to know various effects of incense, curiosity about such new things and the will to imitate and pursue alien culture, resultantly flourishing incense culture. Thus the culture of incense represented many social aspects of T'ang.

A total of 12 mineral commodities significant in domestic output, economy and/or strategy of the Republic of Korea are chosen to examine the structural changes in production and demand-supply of these minerals during the last two decades of her industrialization. These include iron and manganese ores as the raw materials for iron and steel making, copper, zinc and tungsten ores among other non-ferrous metallic minerals, limestone (cement), kaolin, talc, pyrophyllite and graphite among other non-metallic minerals, and anthracite coal as the only domestic source of fossil energy. These are reviewed historically in time-series based on the statistical data which are tabulated and graphed in terms of domestic output, export, import, apparent demand-supply, its increasing rate, and self-sufficiency rate of each commodity. The increasing rates of demand-supply (IRDS) of some more important commodities are compared with those of Gross Domestic Production (GDP) and Economic Growth Rate (EGR) to evaluate how the IRDS contributed to the GDP and EGR. The major results revealed are as follows: Among the 12 commodities, the domestic output of 8 commodities appeared to have grown with steady upward trends: they are ores of lead, zinc and tungsten, limestone (cement), kaolin, talc, pyrophyllite and anthracite coal. Two commodities, ores of iron and copper, continued with unchanging or slightly declining trends and varied fluctuations, in spite of their cardinal importance to the heavy industry and strategy of Korea. The remaining two, graphite and manganese ore, have gradualy declined in domestic output in which the former has still enough resource potential but the latter has not and virtually ceased its domestic output. Trade patterns for mineral commodities in the Republic of Korea during the last two decades have changed greatly, being marked by a shift from mineral-exporting to mineral importing, mainly because of increasing consumption of mineral raw materials for industrialization rather than beceuse of decreasing output of domestic mineral commodities in quantity. In terms of trade patterns, the 12 commodities concerned in this study can be classified into the following four groups. The 1st group - ores of lead and tungsten have only been exported without imports. The 2nd group - amorphous graphite, and pyrophyllite have mainly been exported but partly been imported. The 3rd group - kaolin, talc and crystalline graphite have equally been exported and imported, but quantity of imports have rapidly been increased with time. The 4th group - ores of iron, manganese and zinc have shifted from exports to imports during the industrialization, particularly owing to the initiation of iron and steel making by the Pohang Iron and Steel Company in the middle 1970' s and the new establishment of the Onsan Zinc Refinery in the late 1970' s. All of the 12 commodities under considerations were far above 100% in self-sufficiency rate before or in the early 1960' s. Recently, however, most of them have been declined to below 100% except for those of limestone (cement) and pyrophyllite. It is particularly serious to identify that the self-sufficiency rates of the three important metallic minerals, iron, copper and manganese ores in 1982 appeared to be 5.1%, 0.5%, and 0.01%, respectively. The average self-sufficiency rate of the total domestic minerals produced in 1982 was 14.4% (in value) for that year. Mining industry appeared to be extremely high in its intermediate demand rate whereas its intermediate input rate to be quite low indicating that mineral raw materials have been exerted strong forward linkage effects upon the other industries rather than backward linkage effects. In comparing the curves of increasing rates of demand-supply of several major minerals - iron ore, manganese ore, copper ore, limestone (cement), kaolin, and anthracite coal - with those of Gross Domestic Production and Economic Growth Rate drawn on every graph, it is clearly shown that the curves of increasing rates of demand-supply comprise around 6 to 7 periods of cycles which roughly harmonious with those of the curves of GDP and EGR, except for the curve of anthracite coal of which the configuration seems to have resulted from the (artificial) government's mineral policy rather than from economic free market mechanism. The harmonic feature of these curves well suggests that the increasing rates of demand-supply of major minerals have been significantly contributed to the GDP and EGR. In addition, the wider amplitudes of the iron, manganese and copper curves than those of the limestone (cement) and kaolin curves indicate that the contribution of the former, metallic commodities, has been greater than that of the latter, non-metallic commodities.

1990년 시장평균환율제도에서 1997년 외환위기 이후 자유변동환율제도까지 환율제도의 변경과 더불어 자본시장 자율화로 인하여 환율의 변동성이 증대되고 있다. 이와 같은 환율 변동성의 증대는 우리나라와 같은 소규모 개방경제와 수출중심의 경제기반 하에서 주요관심사가 아닐 수 없다. 이에 본 연구는 자유변동환율제도를 설명하기 위해 이론적으로 고안된 통화론적 접근방법을 적용하여 우리나라의 대미 환율 결정요인을 실증적으로 분석하였다. 이들 모형에 근거하여 설명변수로는 통화량과 소득, 이지율, 자본수지, 엔화환율, 교역조건 등을 선택하였다. 또한 분석기간을 1990년부터 2009 년으로 하여 외환위기 전 후 균형관계의 차이를 비교분석할수 있도록 하였다. 공적분 검정과 벡터오차수정모형을 통한 실증분석 결과, 우리나라에서도 통화적 접근방법은 자유변동환율제도 기간인 외환위기 이후기간에 더 설명력 있는 것으로 나타났다. 외환위기 이후기간에는 통화량, 소득, 단기이자율로 구성된 가격신축적 Bilson 모형이 가장 우세하였으며, 환율과 장기적 관계에 았는 변수들이 환율의 단기변동에도 영향을 미치는 것으로 드러났다.
