  • Nasopharyngeal carcinoma (NPC) is a disease with distinct ethnic and geographic distribution. The incidence of NPC in Chinese residing in Asia has declined over the last few decades, but NPC mortality trends in the entire Chinese population over time have not been systematically evaluated. In this study, we examined NPC mortality at the national level in China between 1973-2005. Mortality rates were derived from the databases of national retrospective surveys on cancer mortality conducted in the periods of 1973-1975, 1990-1992, and 2004-2005, respectively. NPC was classified according to the International classification of diseases. Age-adjusted mortality rates were calculated by direct standardization according to the world standard population. Trends in rates were evaluated by age, gender, geographic areas, and socioeconomic status. From 1973 to 2005, there was a general trend of decrease in NPC mortality in China, with higher rates in the south on a downward trend in the north. The age-standardized NPC mortality rates were 2.60 per 100,000 in 1973-1975, 1.94 per 100,000 in 1990-1992, and 1.30 per 100,000 in 2004-2005, respectively. The trend was similar in both men and women, in both urban and rural areas, but the declining rates in females were more remarkable than in males. The mortality rates were higher for the age groups above 50 years than those less than 50 years of age, both showing downward trend over 30-year period. In summary, the overall NPC mortality has consistently decreased in China over the past three decades, particularly in women and in old adults.

  • 잠재증발량에 대한 많은 경험식들이 제시되어 있지만 각각의 방식에 대한 국내의 적용성에 대하여 구체적으로 비교검토된 사례는 매우 제한적이다. 널리사용되고 있는 Hargreaves식은 비교적 단순한 형태를 지니고 있으나 대기수분량을 계산에 반영치 못하는 한계를 지니고 있다. 본 연구에서는 남한 내 다목적 댐 유역의 1973-2014년 기상자료를 바탕으로 Penman-Monteith (P-M) 식과 Hargreaves식을 통해 계산한 잠재증발산량($ET_{PM}$, $ET_{Harg}$)의 비교를 통해, Bouchet (1963)의 보완 관계 관점에서 $ET_{Harg}$$ET_{PM}$에 비해 과다 산정되는 경향이 있음을 확인하였다. 이에, 1973-2004년에 대한 각 댐 유역의 기상관측소 단위별로 산정된 $ET_{PM}$을 상대적인 정해로 간주하여 Hargreaves식의 매개변수를 추정하였다. 추정된 매개변수는 동일 관측소의 2005-2014년 기상자료와 함께 Hargreaves식에 적용 후, 다목적 댐 유역별 $ET_{PM}$$ET_{Harg}$을 산정하여 검정을 수행하였다. 수행 결과, Hargreaves 식의 매개변수 조정 전 $ET_{PM}$과의 Nash-Sutcliffe 일치계수는 0.47-0.79 (1973-2004), 0.28-0.76 (2005-2014)이었고, RMS 오차는 17.79-25.85 (1973-2004), 18.24-27.40 (2005년-2014년)이었으나, 매개변수 조정 후 Nash-Sutcliffe 일치계수는 0.96-0.98 (1973-2004), 0.95-0.98 (2005-2014)로, RMS 오차는 5.78-7.11 (1973-2004), 4.97-6.95 (2005-2014)로 조정 전 보다 향상된 결과를 보였다.

  • We used the Braun-Blanquet method to study coastal dune vegetation of South Korea. Coastal vegetation was monitored in thirty sites from April 2004 to September 2005. Seventeen plant communities were classified into five groups as follows: A. Two associations of herbaceous sand dune plants in Salsoletea komarovii Ohba, Miyawaki et Tx. 1973 (Calystegia soldanella community, Lathyrus japonicus-Calystegia soldanella community), B. Twelve associations of herbaceous perennial sand dune plants in Glehnietea littoralis Ohba, Miyawaki et Tx. 1973 (Carex pumila community, Elymus mollis community, Vitex rotundifolia-Elymus mollis community, Ixeris repens community, Elymus mollis-Ixeris repens community, Lathyrus japonicus community, Messershmidia sibirica community, Glehnia littoralis community, Carex kobomugi community, Calystegia solda-nella-Carex kobomugi community, Ishaemum anthephoroides community, Zoysia macrostachya community), C. One association of shrubby perennial sand dune plant in Viticetea rotundifoliae Ohba, Miyawaki et Tx. 1973 (Vitex rotundifolia community), D. One association of shrubby perennial sand dune plant in Rosetea multiflorae Ohba, Miyawaki et Tx. 1973 (Rosa rugosa community), E. The naturalized community (Diodia teres community).

  • The purpose of this study is to compare and analyze the print form of UDC(Universal Decimal Classification) standard edition which was published by British Standards Institution in 2005 to Korean edition which was published by Korea Scientific & Technological Information Center in 1973, and to suggest the appropriate revision directions of future Korean edition. This study suggests that the future Korean edition should be revised based on the Master Reference File and should be a print edition which is composed of systematic tables and alphabetical index from the standard edition. In addition, the future Korean edition needs to strengthen international universality and to extend synthetic method using its auxiliary tables.

  • Since the 1970s, rapid Industrialization has brought urbanization nationwide. In this paper, thirty one years data(1973-2003) ate used to evaluate variability of major cities. Before assessing the context between urbanization and variability of rainfall, the rural areas are selected to compare with urban ones. Thus, average, trends, variations, and nonparametric frequency analysis methods were employed for evaluating variation of annual precipitation, seasonal precipitation, 1 hour annual maximum design rainfall and 24 hour annual maximum design rainfall for both urban and rural areas. The result have shown that summer precipitation relatively increased In urban areas compared to that in rural areas.

  • 독점금지법과 지적재산권 양자간에는 항상 긴장관계가 존재해 왔다. 이러한 근본적인 대립관계에도 불구하고, 양자는‘소비자 복지의 극대화’와‘창조적 활동과 공정한 경쟁의 촉진’이라는 공통된 경제적 목적을 공유하고 있다(WARD S. BOWMAN, JR.,PATENT & ANTITRUST LAW: A LEGAL & ECONOMIC APPRAISAL 1-14 (1973). 그럼 과연 독점금지법이 지적재산권자 의 권리행사를 제한할 수 있을까? 만약 그것이 가능하다면, 어떤 경우에 지적재산권의 행사가 금지되는 것인가? 이하에서는 최근의 ‘마이크로소프트(MS)의 끼워팔기(tying) 사건’과 특허권자에 의한 거래거절행위의 위법성 여부가 문제됐던 미국의‘코닥사건’을 살펴봄으로써 이러한 궁금증을 해결하고자 한다.

  • Since 1970s, rapid industrialization brought urbanization nationwide. In this paper, precipitation changes have been studied for Seoul and other 6 major cities using 31 years of precipitation data from 1973 to 2003. In addition, to consider the other global climatic impacts including El Nino events, precipitation change comparisons have been made between urban and rural areas. Thus, statistical analysis methods have been adopted for annual precipitation, summer precipitation, 1 hour annual maxima series, and 24 hour annual maxima series for both urban and rural areas. The result yields that annual and summer precipitation have been increased in urban areas compare to rural areas.

  • The Arbitration Act of Korea was promulgated in 1966. Since the promulgation of Arbitration Act of Korea, consecutive amendments took place in 1973, 1993, 1997, 1999, 2001 and 2002. Among the various set of amendments, those of 1999 were designed to accommodate the UNCITRAL Model Law on international Commercial Arbitration of 1985. Korea has acceded to special international conventions on dispute settlement such as the New York Convention of 1958 and the Washington Convention of 1965. The Korean Commercial Arbitration Board(KCAB) administers the arbitration proceedings in accordance with its Arbitration Rules approved by the Korean Supreme Court. Since the establishment of the first Arbitration Rules in 1966. consecutive amendments took place in 1973, 1981, 1989, 1993, 1996, 2000 and 2004. The KCAB plans to enact the International Arbitration Rules, which will be available to disputing parties in addition to the KCAB Arbitration Rules. In 2005, arbitration applications received at KCAB recorded a historic high at 213 cases, an increase of 22% from 175 cases in 2000. But in 2005, the total amount involved in the arbitration cases decreases to US$ 129 million, a decline of 63% from US$ 346 million in 2000. The KCAB should take the following measures for activating the commercial arbitration system: the globalization of KCAB, the advertisement of arbitration system, the security of qualified arbitrators, and the enhancement of the secretariat service. In conclusion, the KCAB should make efforts for the development of the arbitration system and for the upgrade of customer satisfaction. Moreover the KCAB should make further efforts to grow into a global arbitration institution as well as strengthening relations with international arbitration institutions.
