  • This study investigated the cause of the heavy snowfall that occurred in the East Coast of Korea from 6 February to 14 February 2014. The synoptic conditions were analyzed using blocking index, equivalent potential temperature, potential vorticity, maritime temperature difference, temperature advection, and ground convergence. During the case period, a large blocking pattern developed over the Western Pacific causing the flow to be stagnant, and there was a North-South oriented High-to-Low pressure system over the Korean Peninsula because of this arrangement. The case period was divided into three parts based on the synoptic forcing that was responsible for the heavy snowfall; detailed analyses were conducted for the first and last period. In the first period, a heavy snowfall occurred over the entire Korean Peninsula due to strong updrafts from baroclinic instability and a low pressure caused by potential vorticity located at the mid-troposphere. In the lower atmosphere, a North-South oriented High-to-Low pressure system over the Eastern Korea intensified the easterly airflow and created a convergence zone near the ground which strengthened the upslope effect of the Taebaek Mountain range with a cumulative fresh snowfall amount of 41 cm in the East Coast region. In the last period, the cold air nestled in the Maritime Province of Siberia and Manchuria strengthened much more than that in the first half and extended to the East Sea. The temperature difference between the 850 hPa air and the SST was large and convective clouds developed over the sea. The highest cumulative fresh snow amount of 39.7 cm was recorded in the coastal area during this period. During the entire period, vertically oriented equivalent potential temperature showed neutral stability layer that helped the cloud formation and development in the East Coast. The 2014 heavy snowfall case over the East Coast provinces of Korea were due to: 1) stagnation of the system by blocking pattern, 2) the dynamic effect of mid-level potential vorticity of 1.6 PVU, 3) the easterly air flow from North-South oriented High-to-Low pressure system, 4) the existence of vertically oriented neutral stable layer, and 5) the expansion of strong cold air into the East Sea which created a large temperature difference between the air and the ocean.

  • 동해 남서부 해역의 해양생태계에 큰 영향을 미치는 연안용승의 변화를 파악하기 위해 1948년 1월부터 2018년 9월까지의 NCEP/NCAR 재분석자료를 이용하여 용승지수를 계산하였다. 평균 용승지수는 4월부터 8월까지 용승이 발생하는 양의 값이 보이며 7월에 최대 값이 나타났다. 용승지수의 장기 변화는 6월과 7월에 통계적으로 유의미한 감소추세가 나타났으며, 5, 6, 7월 용승지수의 합도 통계적으로 유의미한 감소 경향을 보였다. 한반도 주변의 대기압 분석을 통하여 용승지수의 변화 추세는 동해남부해역을 기준으로 북서쪽 영역($35-50^{\circ}N$, $114-129^{\circ}E$)의 기압 변화 추세의 영향이라는 것을 밝혔다. 최근 7년간(2012년-2018년)의 용승지수 분석결과 2017년 7월에 용승지수가 표준편차의 3배 이상 높은 것을 발견하였다. 이것은 중국 북동쪽 지방에 평년과 다르게 저기압이 발달하였고 북태평양고기압이 일본과 대만 사이까지 영향을 주어 동해 남부에 큰 기압 차이가 발생했기 때문이었다. 반면에 평년에 비하여 북쪽의 저기압과 남쪽의 고기압의 영향이 적었던 2018년 7월은 용승지수가 음의 값이었다. 동해남부 연안용승지수는 기후변화에 따라 감소하는 경향을 보이고 경년변동이 커서 생태환경에 대한 영향을 파악하기 위해서는 지속적인 모니터링이 필요하다.

  • Khori(高麗) refers to the Chaabog(reindeer) that live on lichens(蘚) on Mt. Soyon(鮮) in which pastures are the cold and dry plateau of North Eurasia. Thus, the origin region of the Khori or Koguryo that are the ancestors of the reindeer-herding pastoral nomads(馴鹿 遊牧民) can be said to be the Steppe-Taiga-Tundra pastoral areas of North Eurasia and North America. When the pastoral nomads moved on to the great mountain(大山) zone of the Jangbaek(長白) to the Baekdu(白頭) Mountains, they could have been in contact with pastoral farmers or agricultural farmers living there and they became the farmers remaining on agricultural farms. They were the Koryo people, the ancestors of Korea. Staying in one place, they gradually forgot the origin of their reindeer-herding pastoral nomadic history in the Northwest area of Mt. Soyon, the small mountain(小山) zone of the Steppe-Taiga-Tundra pastoral areas. In other words, they lost their identity as reindeer-herding pastoral nomads when they entered the agricultural area after leaving the pastoral area. However, since their basic genes had already formed when they lived on the cold and dry plateau of North Eurasia, it is possible to study their pastoral nomadic history focusing on 'the minority living in the broad area(廣域少數)', by utilizing highly advanced biotechnological science and focusing on genes and information technology innovation, and removing various past hindrances in research. Therefore, it is not so difficult to restore the reindeerherding pastoral nomadic history of the Koguryo(高句麗) people and secure their pastoral nomadic identity, of which the first steps have already been taken into their historical stages. The Eurasian continent and the Korean peninsula, especially the cold and dry plateau of North Eurasia and the Korean peninsula have been closely related to each other ecologically and historically. They can never be a separate space at all. The Eurasian continent lies horizontally east to west and thus, the continent forms an isothermal zone. Also, since the time of producing their own foods, it was relatively easy for people with their technology to move to other places owing to the pastoral nomadic characteristic of mobility. Unlike the Chungyen(中原) region, western Asia and the regions covering the Siberia-Manchu-Korean peninsula where food production revolution was first made were connected to the Mongolian lichens route(蘚苔之路: Ni, ukinii jam) and steppe roads. Although the ecological conditions of nature have changed a bit throughout a long history, it was natural for the many tribes in North Asia living on the largest Steppe-Taiga-Tundra area in the world to have believed 'the legends related to animals in relation to their founders and ancestors(獸祖傳說)'. Assuming that Siberian tigers and the tigers living on Mt. Baekdu were connected ecologically and genetically because of the ecological characteristics of the animals, and their migration from plateau to plateau, we would suspect that the Chosun(朝鮮) tribe living on Mt. Baekdu were ethnically and culturally more closely connected to the farther removed Ural-Altai tribes that lived on the cold and dry plateau region than to the Han(i14;) tribe who lived in Chungyen(中原) that was close to Mt. Baekdu. More evidence is the structure of the Korean language which has the form of 'Subject + Object + Verb', which is assumed to have originated from the speedy lifestyle of the reindeer-herding pastoral nomads. The structure is quite different from that of the Han(漢) language, which is based on agricultural life. Also, it is natural for reindeer riding reindeerherding pastoral nomads or horse-riding sheep-herding pastoral nomads(騎馬, 羊遊牧民) to have held military and political power over the region and eventually to have established an ancient pastoral nomadic empire in the process of their conquest of agricultural regions. The stages for founding global empires in the history of mankind maybe largely divided into two, in terms of ecological conditions and occupations. They are the steppes and the oceans. Of course, the steppe-based empires were established based on the skills to deal with horses and the ability to shoot arrows while riding horses, along with the use of iron ware in the 8th century BC. The steppe-based empires became the foundation for an oceanic empire, which could have been established by the use of warships and warship guns since the 15th Century. Based on those facts, we know that Chosun, Puyo(夫餘), and Koguryo are the products of a developmental process of pastoral nomadic empires on the steppes. Maybe we can easily find the pastoral nomadic identity of the Koguryo more than we expected when we trace the origins and history of the Korean tribe living in the pastures located in the northwest area of Mt. Jangbaek by focusing on pastoral nomadic mobility and organization just as we have investigated the historic origins of Anglo-Saxons in America by focusing on the times before the 15th Century. In the process, we should keep in mind that English culture originated from the Industrial Revolution and was directly delivered to the American continent, although America was far from England and was not an intermediate point on long sojourns either. Further, American culture came back to England in a more advanced form later. The most important thing currently to be resolved is to cause Koreans to look back on their own history in a freer way of thinking and with diverse, profound, and sharp insight, taking away the old and existing conventional recognition that is entangled with complicated interests with Korean people and other countries. The meanings of Chosun, Khori, and Solongos have been interpreted arbitrarily without any historic evidence by the scholars who followed conventional tradition of fixed-minded aristocrats in an agricultural society. If the Siberian cultural properties of the stone age, the earthenware age, the bronze age, and the iron age are analyzed in such a way, archaeological discovery will never be able to contribute to the restoration of the Koguryo's pastoral nomadic identity. One should transcend the errors that tend to interpret the cultural properties discovered in the pastoral nomadic regions as not being differentiated from those of agricultural regions and just interpret them altogether from the agricultural point of view. A more careful intention is required in the interpretation of cultural properties of ancient Korean empires that seem to have been formed due to mutual interactions of pastoral nomadic and agricultural cultures. Also, it is required that the conventional recognition chain of 'reverse-genes' be severed, which has placed more weight on agricultural properties than pastoral nomadic ones, since their settlement on agricultural farms was made after the establishment of their ancient pastoral nomadic empires. There is no reason at all to place priority on stoneware, earthenware, bronze ware, and iron ware than on wooden ware(木器) and other ware which were made of animal skins(皮器), bones and horns(骨角器), in analyzing the history in the regions of reindeer or sheep pastures. Reading ancient Korean history from the perspective of pastoral nomadic history, one feels strongly the instinctive emotions to return to the natural 'mother place'. The reindeer-herding pastoral nomadic identity of the Koguryo people that has been accumulated in volumes in their genes and hidden deep inside and have interacted organically could be reborn with Burqanism(Burqan refers to 不咸 in Chinese), which was their religion by birth and symbolized as the red willow(紅柳=不咸). The mother place of the Koguryo's people is the endless vast green pastures of North Eurasia and North America, where we anticipated the development of Korean livestock farming following the inherent properties in the genes of the reindeer-herding pastoral nomads with Korean ancestors. We anticipate that the place would be the core resource that could contribute to the development of life of living creatures following the inherent properties of their genes and biotechnological factors. In other words, biotechnology used for a search for clues on the well-being of humans could be the fruit brought by Burqanism of the Koguryo people and the fruit of the globalization of Korean livestock farming. It is the Chosun farmer in China come from the vast nomadic reindeer pastures of North Eurasia that resolved the food problem of a billion Chinese people with lowland paddy rice seeds (水稻) by transforming Heilongjiang Province(黑龍江省) into an oceanic lowland paddy rice field(水田). Even Mao Tse-tung(毛擇東) could not resolve the food problem by his revolution campaigns for tens of years. Today is the very time that requires the development of special livestock farming following the inherent properties of the ancient Korean reindeer-herding pastoral nomads that respected the dignity of life on the cold and dry plateau of North Eurasia and the America continent. I suggest that research should be started from the pastures of the Dariganga Steppe in East Mongolia that was the homeland of Hanwoo(韓牛) and the central horse-herding steppe place(牧馬場) of Chingis Khan's Mongolia. The Dariganga Steppe is awash with an affluent natural environment for pastoral nomadic living however, the quality of life of the pastoral nomads there is still low. I suggest we Koreans, the descendents of the Koguryo, should take our first steps for our livestock farming business project and develop the Northern nomadic pastures, here at the pastures of the Dariganga Steppe, which is the Mongolian core place of state-of-the-art technology for military weapons.

  • Loulan was an ancient kingdom located on the northeast of the Taklamakan Desert, a diverging point between the north and south of Silk Road, on the east of the current Turpan, from the 2nd century BC and the 7th century A.D, absorbing and propagating culture of both sides through active trade. Meanwhile, as many previous research investigations suggest the early trade between Korea and the countries bordering on Western China, characteristics of Loulan costume have been found to have similarity to those of ancient Korean costume. Also, it can be compared to costume in other surrounding regions. Therefore, it is a highly valuable region in researching ancient costume. This study examined the historical background of Loulan and its relationship with ancient Korea, analyzed the clothes found in historic sites of Louland and Niya, and compared costume elements of Loulan and those of Korea. The result of the study shows that first, the Loulan Jeogori was based on the Jikryeonggyoim, with Chaksu, narrow sleeves and the length coming between below the chest and above the bottom, and the line decoration and waist belt were very similar to Korean costumes, as well as the Banryeong, curved collar and Bansu, short sleeves. Second, the types of pants included Gunggo, characterized by closed bottom and many creases, and Daegugo, wide-leg trousers, which are very similar in shape to the Korean Shilla lay sculpture, Stele To Martyr Yi Ch'a-don, Yangjikgongdo and Wangheedo. Third, in accessories as well, the Jowu stuck on the Gwanmo is similar in the shapes to Korean costume.

  • Orientalism은 동양을 서양과는 다른 이질적 인 대상, 괴상하고 후진적이며 수동적 인 특성을 지닌 열등한 타자로 서양인의 무의식 속에 내면화되어 왔다. 아시아를 일정한 지배의 틀 속에 가두는 문화적 장치와 담론의 체계인 Orientalism은 원래 남유럽과 북아프리카를 포함한 서남아시아에 해당하는 서유럽 중심의 용어였으며, 비 서구사회는 서구문명을 수용함으로써만 발전할 수 있다는 논리의 사상이다. 따라서 이러한 용어의 무분별한 사용은 부적절하다. 또한 아시아의 이미지나 복식양식을 차용한 서구의 아시안 룩에 아시아 본래의 정신은 사라졌다고 하여도 아시아를 저급한 타자로 인식한 것에서 비롯된 것이 아니다. Asian Ethnic Look은 동양적 미학에 매료되어 동양의 이미지나 양식을 차용한 서양의 복식이므로 Orientalism의 속성과는 차이가 있다. 국내의 패션계에서는 이에 대한 분별없이 혼용하여 사용하고 있고, 특히 Orientalism Fashion 또는 Oriental Look이라고 자주 사용하고 있다. 아시아의 복식이나 이미지를 기괴하게 조작한 일부 특정한 복식만을 Orientalism Fashion 또는 Oriental Look이라 해야 하며, 이를 제외하고는 'Asian Look', 'Asian Fashion', 'Asian Ethnic Look' 등으로 바꾸어 쓰거나, 'Korean Look' 등의 개별 국가나 지역 명으로 바꾸어 쓰는 것을 분명히 해야 한다 한국을 비롯한 아시아는 서구 중심의 수동적 입장이 아니라, 세계 패션산업의 중심축 중 하나로써 세계 패션을 리드하고 있다. 이제는 우리 스스로가 서구중심의 이분법적 편견을 해체해 나가야 할 것이다.

  • 일반적으로 인도양 동쪽 해수면 온도는 따뜻하고, 서쪽 해수면 온도는 차갑다. 이러한 인도양 동/서쪽의 해수면 온도 변화는 인도 해양 다이폴 현상(Indian Ocean Dipole Mode, IODM)이 그 원인이다. 다이폴의 양의 위상은 서쪽 인도양에 양의 SST 아노말 리가 나타나고, 남동 인도양에는 음의 SST 아노말리가 나타나고 음의 위상은 이와 반대의 SST 아노말리가 나타난다. 반면 태평양의 경우, 일반적으로 서쪽 해수면 온도는 따뜻하고, 동쪽 해수면 온도는 차갑다. 중앙/동(서) 태평양 해양의 양(음)의 SST 아노말리가 현상이 나타날 때는 엘니뇨 시기이다. 이와 반대의 SST 아노말리 현상은 라니냐 시기이다 이러한 태평양의 대기-해양간의 상호작용으로 나타나는 현상을 엘니뇨 난방진동(El Nino Southern Oscillation, ENSO)이라 한다. 본 연구에서는 IODM과 ENSO현상에 따른 동아시아 몬순 변동성을 분석하기 위해 관측자료와 NCAR MCA모델 자료를 사용하였다 IODM과 ENSO 현상과 관련된 SST 아노말리 5가지 실험을 수행하였다. IDO모드는 최고의 값이 나타난 이후 약 $3\~4$계절의 시간 지연을 가지고 동아시아의 여름 몬순 활동에 영향을 주는 반면, ENSO는 동아시아 여름 몬순과 같은 계절에 영향을 준다. IODM 음(양의)위상과 태평양에서의 엘니뇨(라니냐) 현상은 한국과 일본지역에서 몬순 활동을 강화(억제)하는 역할을 한다. 반면 중국 지역에서는 IDOM과 몬순 변동성과는 별다른 연관성이 없는 것으로 나타났다. 그러나 엘니뇨(라니냐)일 때, 중국 지역에서 몬순 활동은 억제(강화)되는 경향을 보였다. IODM은 북태평양 아열대 고기압이 강화 할 때 나타나고, ENSO는 북서 태평양 알류산 저기압의 영향으로 나타난다. 따라서 태평양으로부터 동아시아 쪽으로의 수분 공급은 아열대 고기압과 알류산 저기압의 강화/약화에 의해 결정된다.

  • 한국전쟁의 결과 한반도의 허리에 해당하는 DMZ 지역은 반세기 이상 인간의 관심에서 잊혀진 공간이었다. 그러나 최근 국 내외적으로 DMZ에 대한 관심이 고조되면서, 오늘날 DMZ를 대상으로 하는 연구는 점차 활발해 지고 있다. 그러나 정작 연구의 대상인 DMZ의 공간적 범위에 대한 연구는 매우 미약하다. 그마저도 선행연구를 분석한 결과 대부분의 연구에서 군사분계선과 DMZ, 한강하구 중립지역, 그리고 NLL에 대한 기술에 있어서 공간적인 오류를 범하고 있었다. 본 연구에서 조사한 결과, 동해안 고성의 명호리에서 서쪽의 임진강 하구에 이르는 군사분계선의 길이는 약 238km(148마일)이고, 군사분계선을 따라 설정되어 있는 DMZ의 면적은 약 $903.8km^2$로 측정되었다. 이는 현재 '155마일 휴전선' 등과 같이 남북을 양분하는 공간을 지칭하는 용어에 대한 재정립이 필요함을 의미하는 것이다.

  • The six-year (2000~2005) record of aerosol optical thickness (AOT or $\tau$) data from the Moderate Resolution Imaging Spectroradiometer (MODIS) was analyzed over the Northeast Asia. The MODIS AOT standard products (MOD04_L2) over both ocean and land were collected to evaluate the spatial and temporal variability of the atmospheric aerosols over the study region ($32^{\circ}N{\sim}42^{\circ}N$ and $115^{\circ}E{\sim}133^{\circ}E$). The monthly averaged AOT result revealed slight changes(${\pm}0.002{\tau}/month$), which was almost unchangeable, over Korea. In contrast, the large AOT values (> 0.6) and a significant AOT increase (> 0.004 ${\tau}/month$) over East China were observed. For the analysis of spatio-temporal variability of AOT values, study area was divided by six sectors (I: North-East China, II: East China, III: Yellow Sea, IV: Korea Peninsular, V: East Sea, and VI: South Sea and Western part of Japan). The considerable result showed that particularly high AOT contribution was observed over sector I (32.5%) and II (25.5%) where some major urban and industrialized areas and agricultural fields are located and other cases were observed 13.2%, 14.6%, 7.1%, 7.0% over sector III, IV, V, and VI, respectively. In addition, yearly AOT changes based on seasons are observed differently at each sector but increasing trends reveal in summer and fall over all sectors.
