  • Fog deposition onto the cool-temperate deciduous forest around Lake Mashu in northern Japan was estimated by the inferential method using the parameterizations of deposition velocity and liquid water content of fog (LWC). Two parameterizations of fog deposition velocity derived from field experiments in Europe and numerical simulations using a detailed multi-layer atmosphere-vegetation-soil model were tested. The empirical function between horizontal visibility (VIS) and LWC was applied to produce hourly LWC as an input data for the inferential method. Weekly mean LWC computed from VIS had a good correlation with LWC sampled by an active string-fog collector. By considering the enhancement of fog deposition due to the edge effect, fog deposition calculated by the inferential method using two parameterizations of deposition velocity agreed with that computed from throughfall data. The results indicated that the inferential method using the current parameterizations of deposition velocity and LWC can provide a rough estimation of water input due to fog deposition onto cool-temperature deciduous forests. Limitations of current parameterizations of deposition velocity related to wind speed, evaporation loss of rain and fog droplets intercepted by tree canopies, and leaf area index were discussed.

  • 풀무치(Locusta migratoria)는 벼과 작물(벼, 옥수수 등)에 큰 피해를 주는 세계적으로 유명한 메뚜기목 해충의 하나로서 밀도요인에 따라 형태와 행동적으로 구별되는 단독형(solitaria)과 군집형(gregaria)을 나타낸다. 풀무치는 전세계적으로 다양한 형태적인 변이가 알려져 있으나 최근의 분자생물학적 연구에 따르면 2가지 계통, 즉 남방계통(아프리카, 남유럽, 동남아시아, 호주)과 북방계통(동아시아, 유라시아)으로 나뉜다. 2014년 8월 전남 해남군 산이면에서 군집형 약충들이 대발생하여 주변 잡초 및 작물(벼, 기장)에 큰 피해를 주었다. 우리나라에서 군집형 풀무치의 발생에 대한 명확한 학술적 보고는 이번이 처음이다. 해남지역의 풀무치 대발생 지점에서 채집한 풀무치 12개체의 COI 염기서열을 분석한 결과, 0.0%-0.9%의 유전적 변이를 보였으며, 모두 북방계통에 속했다.

  • In September 2013, President Park Geun-hye announced her controversial "Look North" policy, of which the most salient aspect is the "Eurasia Initiative". This comprises various proposals designed to overcome existing constraints by developing new markets and creating new economic partners in continental areas from which South Korea has been alienated since the end of World War II, and this dovetails nicely with China's One Belt, One Road Initiative. The concepts of the "Silk Road Rail Express (SRX)" and the "East Sea Rim Maritime Community (ESRMC)" have also been discussed. SRX is at present a purely symbolic railroad project intended to encourage individual, cultural, trade and diplomatic exchanges. ESRMC is a model for establishing an ad hoc community to promote regional economic cooperation around the East Sea. President Park's Eurasia Initiative will provide South Korean investment for the Northeast to complement Russian plans, like the "Northern Energy Road" being built by Gazprom, and Chinese plans, like the Chang-Ji-Tu Development Plan for the North Korean port of Rajin. China's trade, as well as its energy and food supplies, pass through the Strait of Malacca and the Indian Ocean, and are thus vulnerable to interdiction by India or the US. China is therefore trying to reduce its exposure geopolitical risk by establishing a network of corridors between the Belt and the Road to provide alternative paths. The "China-Pakistan Economic Corridor" and the "China-Myanmar Economic Corridor" provide such connections, and South Korea hopes that SRX and ESRMC can become part of a "China-South Korea Economic Corridor". This concept could do much to revitalize the underdeveloped northern provinces of China and Russia's Far East, not to mention North Korea. By linking up the Trans-Siberian Railway, the Trans-China Railway, the Trans-Mongolian Railway and the Trans-Korean Railway all these Asian countries will be connected to one another, and ultimately to Europe. An interim connection between China and South Korea using a rail-ferry has also been proposed.

  • 베 한필이 작은 대통이나 여인들의 식기인 바리 안에 들어간다 하여 '통포', '발내포' 등으로 불리기도 한 '북포'는 조선시대 함경도 육진 지역에서 생산하던 올이 가늘고 고운 삼베이다. 우리나라는 1950년 한국전쟁의 발발로 인해 국토가 남북으로 분단되었다. 이에 북한 지역의 생활 관습이나 전통 기술 등, 그 정보를 구체적으로 확인하기 어려운 실정으로 그 지역의 삼베 제작 기술 또한 전해지고 있지 않다. 이 논문에서는 조선 후기 북포 제작 공정이 기록된 유일한 문헌인 "오주연문장전산고"를 통해 북포 제작의 특징을 살펴보고, 이를 근대기 문헌 기록과 비교하여 기술의 변천과 그 의의를 짚어보고자 하였다. 이 과정에서 19세기 함경도 육진 지역의 제섬 방식이 유럽 및 중국 묘족의 제섬 기술과 유사성이 있음을 발견하였고, 19세기 중반 이후에서 20세기 이전 사이, 함경도 지역의 제섬 기술에 변화가 있었음을 확인할 수 있었다. 북포 제섬 기술 변천은 기술사적 맥락에서 전통공예기술의 선후 관계를 살펴볼 수 있는 사례라 할 수 있겠다.

  • 제2차 고기후 모델링 비교 프로그램(Paleoclimate Modelling Intercomparison Program phase II, PMIP2)의 대기-해양-해빙 접합모형을 통해 얻어진 시뮬레이션 자료를 이용하여 마지막 최대빙하기(Last Glacial Maximum)의 북극 기후변화를 연구하였다. 연구에 이용된 모형은 미국 해양대기청의 CCSM, 독일 막스플랑크 연구소의 ECHAM3-MPIOM, 영국 기상청의 HadCM3M2, 프랑스 라플라스 연구소의 IPSL-CM4, 프랑스 기상연구소의 CNRM-CM3, 일본 동경대 기후연구소의 MIROC3.2, 그리고 중국 대기물리연구소의 FGOALS을 포함해 총 7개로 구성된다. 7개 모형들에 의해 재현된 현재 기후를 관측에 기초로 한 재분석 자료와 비교해 본 결과, 모든 모형에서 관측에 나타나는 북극기후의 특징들이 비교적 잘 재현되었다. 모든 기후 모형들에 마지막 최대빙하기의 대기 이산화탄소 농도를 포함한 온실기체, 지구공전궤도함수, 그리고 빙상 및 지형의 경계 조건이 적용되었다. 빙하기 경계 조건에 대하여 대륙빙하가 발달했던 북미와 북유럽에서 $24^{\circ}C$ 이상의 온도 감소가 나타나는데, 이는 빙하의 발달에 따른 표층의 알베도 증가와 고도의 증가에 기인하는 것으로 여겨진다. 또한 빙하의 발달에 기인하여 북극해에서도 $10^{\circ}C$ 이상의 온도 감소가 나타난다. 여름철에 비해 겨울철 온도 감소가 대체로 더 크게 나타나며, 북극 주변에서 평균 약 $14^{\circ}C$ 정도의 연평균 온도 감소를 보이고 있다. 저위도에 비해 북극 지역의 온도 감소가 모든 계절, 특히 겨울철에 더 크게 나타나는데, 이는 최근 지구 온난화의 정도가 극 지역에서 저위도나 중위도에 비해 더 크게 나타나고 있는 것과도 잘 대비된다. 본 연구결과와 최근의 온난화가 서로 대비되게 일어나기 때문에, 마지막 최대빙하기의 연구를 통해 미래 지구온난화 하에서 나타날 수 있는 기후변화를 간접적으로 이해할 수 있을 것으로 사료된다.

  • This thesis focuses on the study of costume and ornaments of Shilla which had been severely affected by Uighur, and those of Uighur in Uighur self-governing district located in Shin Kang. East Turkestan, in Centrals Asia. This study aims to identifty the way of intergration of Uighur's costume and ornaments into Shilla, and orgins of Shill's costume and ornaments which had amix of internationl elelemnts thoursh cross exchanges, by comparing the differences between the two, and at the same time to clarify the pedigree of Korean costume and ornaments which are said to be udner a severe Chinese influence, by highlingting its uniqueness and originality . The result of the study demonstrates and originality of SHilla by melting foreign cultures into its own style in the process of accepting them. This means that the Shilla has recreated them in t도 form of simplification, and added naturalistic abstratness which is an element of Norther culture. The costume and ornaments are divided into coronets men's costuem, women's costume, and accessories 1. Coroncts A horse-riding man, and the costume type of 유고제 착유지체형 tell the Northern culture's influence on 백화수피기마인물채화담립 and patterns of a lotus flowr and arabesque show the 백화수피기마인물채색답립 has an influence of Buddhism with cluture of bordering countries of Western China , The origin of 뱍회수피제안형건(원정형, 방정형) lies in Northern cultures which can be found in ancient tombs of the Huns in noin-Ila , and stone caves of Jizil in Kochang. The wall paintings in Alexandropol, Murutuk and 돈황 No. 409 cave show that 초화형입식계금관 is under the influence of Northern culture, and Bezerkrick No, 25 cave and 회 번 in Kocho also show 수목녹각형입식관 is under the influence of Northern culture, with its origin in Novecherkaask. In this regard, the transformed coroncts of Shilla has shows a blended culture of Shilla with Nothern, Chinese, and Western cultures. 2. Men's Costume 반령포 derives from cultures of bordering countries of Western China centering around Uighur and Turkey. 연주문 in Uighur prince's costume and in Uighur paintings of Central Asia were reflected into the arts of Shilla in a direct way, and the motive of Uighur was deviatelly expressed at Shilla's arts in the form of simplicity , and naturalistic abstract paintings as in shown at 입수쌍조문 in tiles and brick. Along with this , 고착지체형 costume originates from Eurasia's Northern horseriding costumes as was shown in a golden man in B.C.4-5C which is now possessed by Kazakstan Republic Academy Archelogy Center Museum, and a golden figure from Skitai ancient caves, an the origin is carried away into wall paintings of Kizil No.14. cave in 8c and Astana's early period ancient tomb. No.6. 3. Women's Costume The hair styles of Shilla people are either 변발 or up -style with a lot of hair around it whose origin can be seen in Astana No.216 and No.187 caves of Kochang and Uighur's wall paintings of royal princess's hair style. Astana's middle period No. 206 and No.230 tombs reveal the its origin of 고착장군 while Astana early period No. 6 tomb shows that of 광유풍만형. 4. Accessories The earrings with small golden beads is seen at earring of figure holding a sword in wall painting of figure holding a sword in wall painting of Kizil in about 5 C. and those of a offering people in Sorchuk wall paintings. The earrings with small golden beads originates from a golden pendant of Shivargan, Afganistan, and golden pendants and other golden and metal accessories from Chrioba ancient tombs in Skiti Critia peninsula. Shilla's costume derives from the costume style of horse-ridding man, which proves the fact that Shilla people are horse-ridding peoplewith excellent horse-ridding techniques, and traditions. The people of Shilla are from horse-ridding people of local mounted momads in Northern part of Siberia steppe and this origin of Northern culture had been carried into Uighur in East Turkestan. At the same time , Shilla has a wealth and power since it was rich in gold and iron , thus producing lots of materials made of them. The results of this study emphasizes Shilla's identity and self-control by creating an independent an innovative heterogeneous culture since Shill's active exchanges with East Asia allowed it to accept the most civilized Uighur culture in East Turkestan among Altai languate which had frequent cross contacts with India and Europe.

  • In order to assess the chronic impact of tropospheric ozone on vegetation in the Seoul metropolitan area, it is necessary to quantify ozone exposure. Two ozone indices commonly used to relate ozone exposure to injury of vegetation were calculated. SUM06(SUM of hourly concentrations at or above 0.06 ppm) and AOT40(Accumulated exposure Over a Threshold of 40 ppb) which are widely used as ozone indices in the US and Europe were calculated based on hourly ozone concentrations in 5 areas of Seoul and 5 cities of Kyunggido during 1990~1997. Most SUM06 levels were 1~5ppm.hr, however several areas in Northern and Eastern Seoul reached about 5~7 ppm.hr in 1996~1997. AOT40 values were as high as 17~24 ppm.hr. Although measured SUM06 levels would not be expected to significantly impact vegetation, the overall ozone index, as well as annual average, 95th, and 99th percentile have increased continuously over the last 8 years. Often, ozone concentrations are lower in cities where there is a significant NOx concentration, than in outlying rural agricultural areas where NOx scrubbing is not as important. Concentrations greater than 40 ppb, which can cause chronic ozone toxicity to vegetation, were found mostly in the summer and constitutued about 5~15% of total hourly ozone cocentrations.

  • Many studies such as Pepin (1999a; 1999b), Kaiser (2002), and Park & Leung (2006) revealed that there is a strong dependence of mathematics teaching on cultural traditions in different countries. This study was set up as a detailed comparison between the intended curricula in Berlin and Hong Kong to explore how cultural tradition influenced the intended curriculum. In this study, the intended curriculum is what the (local, state or national) curriculum developers stipulate in the official documents. The German educational system is influenced by the curriculum tradition called Didaktik. Didaktik is a tradition about teaching and learning. Since 16th century, Didaktik has been the most important tool for planning, enacting, and thinking about teaching in most of northern and central Europe (Westbury, 1998). On the other hand, the education system in Hong Kong is influenced by both the Anglo-Saxon curriculum tradition and the Confucian heritage culture (CHC). It was found in this study that, although many studies revealed that there is a strong dependence on cultural traditions of mathematics teaching in different countries, other factors such as social factors or the education system also played an important part in shaping the intended mathematics curriculum. So a simplistic view of dependence of the curriculum on cultural traditions is not warranted. The formation of the curriculum is a much more complicated process encompassing various factors including needs of society, advancement of technology, and government policies at different levels.

  • The Silk Road, a trans-Eurasian network of trade routes connecting East and Southeast Asia to Central Asia, India, Southwest Asia, the Mediterranean, and northern Europe, which flourished from roughly 100 BCE to around 1450, has enjoyed two modern eras of intense academic study. The first spanned a period of little more than five decades, from the late nineteenth century into the early1930s, when a succession of European, Japanese, and American scholar-adventurers, working primarily in Chinese Turkestan (present-day Xinjiang Uyghur Autonomous Region, which comprises China's vast northwest) and China's Gansu Province (to the immediate east of Xinjiang) rediscovered and often looted many of the ancient sites and artifacts of the Silk Road. The second era began to pick up momentum in the 1980s due to a number of geopolitical, cultural, and technological realities as well as the emergence of the New World History as a historiographical field and area of teaching. This second period of fascination with the Silk Road has resulted in not only a substantial body of both learned and popular publications as well as productions in other media but also in an ever-expanding sense among historians of the scope, reach, and significance of the Silk Road.

  • Organic livestock farming in northern European regions has been expanded with the major animals of large ruminants using pastures and grass silages. Organic livestock farming in some European countries has been in rather short of productivity compared to the conventional livestock farming, however since the gap of productivity between organic and conventional livestock farming has been reported to be reduced when the efficiency of management would improve, organic livestock farming has a potential to develop as a clean livestock farming in the future. We expect that organic livestock farming be propelled to a future model of livestock farming in Korea too. As the schemes for realization of organic livestock farming in Korea, firstly a system for the consistent supply of organic feed should be established. Mountainous areas that represents 63 % of total area of Korea could be utilized for the production of organic forages. Uncultivated rice paddy and upland agricultural field could also be used for this purpose. The active application of organic agricultural by-products such as organic rice straw, organic rice bran and SO forth can be considered for organic livestock farming. Secondly, the replacement of anti-biotics for the management of animal diseases should be developed using natural products. Plants and microbes would be good sources of natural products. Thirdly, the realization of organic livestock farming may require a system for certification of the organic farms and consequently the experts to work on.
