  • 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.

  • 2005년 말을 기준으로 우리나라의 농림업 생산액은 총 36.3조원으로 이중 축산업 생산액은 11.8조원으로 전체 생산액의 32.5%를 차지하여 가장 많은 비율을 점유하고 있으며(농림부, 2006), 유제품의 소비량도 꾸준히 증가하여 1인당 63.6kg의 우유․유제품을 섭취하는 것으로 나타났다(농촌경제연구원, 2005). 이 같은 성장은 축산농가들이 국제 경쟁력 확보를 위해 그동안 보여준 각고의 노력과 꾸준한 투자의 결과로 평가되고 있으며, 이제는 축산물이 국민의 식생활에서 없어서는 안될 중요한 위치를 차지하게 되었다. 우리나라의 가축사육두수는 1970년대부터 해마다 계속 증가하여 2005년 말 현재 한우 1,819천두, 젖소 479천두, 돼지 8,962천두, 닭 109,628천수가 사육되고 있으며 사육농가의 전업화로 인하여 농가수는 점차 줄어들고 있는 반면에 농가당 사육두수는 증가하고 있는 실정이다(농림부, 2005). 농가당 평균 가축사육두수는 한우 8.8두, 젖소 51.7두, 돼지 671.4두, 닭 813.0수이며, 이중 부업이 아닌 전업농으로 볼 수 있는 한우 50두 이상의 사육농가가 전체 한우농가의 2.9%, 젖소 50두 이상 사육농가가 46.8%, 돼지 1,000두 이상의 농가가 21.6%, 닭 30,000수 이상의 농가가 1.0%를 차지하고 있어, 젖소가 다른 축종에 비해 전업농의 규모가 가장 많이 이루어졌다고 볼 수 있다(농림부, 2005). 따라서 매년 축산농가로부터 발생되는 분뇨의 양도 증가되고 있으며, 1990년초부터는 가축분뇨가 작물의 비료원으로 쓰이는 순기능보다는 환경오염의 한 요인으로 지목되면서 토양, 수질 및 대기오염이라는 역기능이 더 부각됨에 따라 도시근교의 낙농가, 초지나 사료작물포를 확보하지 못한 목장, 상수원 보호구역내에 위치한 목장에서는 분뇨처리에 고심을 하지 않을 수 없게 되었다. 특히 체격이 크고 방목지 및 운동장 등의 야외에서 사육되는 경우가 많은 젖소는 다른 가축에 비해 분뇨배설량이 많을 뿐 아니라, 운동장 등 축사 외부에서 활동하는 시간이 많기 때문에 주변으로부터 환경을 오염시키는 주범으로 지목을 받아 왔다. 또한 조사료 생산기반인 동시에 생산된 분뇨를 환원해야 할 경지면적이 협소한 상황에서 이루어진 젖소의 규모확대는 가축분뇨의 토양에 대한 부하를 높이게 되었고, 하천의 수질을 오염시키는 환경오염의 주범으로 인식되어 왔다. 이와같은 대내외적인 요인으로 인해 낙농가들은 목장의 규모에 관계없이, 분뇨를 적절하게 처리하는 것이 목장관리에 필수적인 사항으로 인식하게 되었다. 가축분뇨는 2, 3차 산업에서 발생하는 폐기물과는 그 성격 자체가 판이하게 달라 제도적 접근 방식도 나라와 환경에 따라 현격하게 다르다. 미국과 EC의 경우는 가축분뇨 자체를 환경보전재(Natural Resource)로 규정하고 적정한 사용방법을 정립하여 계도(Guide) 하므로서 환경을 보전하는 적극적인 환경보전 제도를 채택하고 있으며, 일본의 경우는 방류수의 수질을 규제하는 소극적 환경보전 제도로 출발했으나 1993년부터는 환경보전형 농업(축산)으로 정책방향을 전환하여 실행해 오고 있다. 우리나라도 이미 1981년부터 가축분뇨에 의한 환경오염 방지제도(법)가 시행되어 왔으나 법의 시행으로부터 25년이 경과한 현재까지도 가축분뇨에 의한 환경오염은 사회로부터 계속 지탄을 받고 있는 상태이다. 가축분뇨의 처리방식은 축종이나 농가 경영여건별로 크게 다르나, 궁극적으로는 경작지에 퇴비․액비 형태로 살포하여 이용하거나 또는 정화하여 방류하는 방법으로 이루어지고 있다. 따라서 젖소분뇨 또는 슬러리 처리에 필요한 시설 또는 활용계획을 세우기 위해서는 젖소로부터 배출되는 분뇨의 특성뿐만 아니라 오염물질 및 비료성분 배출량 추정이 무엇보다 중요하다고 할 수 있다. 본 연구는 젖소분뇨를 효율적이고 적절하게 처리하기 위한 기초자료를 제공하고 국가단위 관리방안을 제시하기 위하여 수행하였다.

  • 근관형성을 위해 표준화된 근관형성기구에 비해 taper가 큰 기구들이 사용되고 있으며 이를 이용하여 형성된 근관은 taper가 큰 근관의 모양을 갖는다. 근관충전방법에 있어 근관의 크기에 적합한 1차적 gutta-percha cone을 선택할 필요가 있다. 본 연구에서는 .04 및 .06 taper의 전동화일로 형성된 근관에 열연화충전법을 위해 가장 적합한 1차 cone을 선택하기 위한 지침 마련의 목적으로, 근단공의 크기와 근관의 taper에 따른 gutta-percha cone의 근단부 근관 내 적 합도를 평가하였다. ProFile$^{(R)}$ .04 taper와 .06 taper를 이용하여 Crown down 방법으로 60개의 모형근관을 형성하였다. 표준화 gutta-percha cone, Dia-Pro ISO-.04$^{TM}$ 및 .06 gutta-percha cone, MF, F, FM 및 M 크기의 비표준화 gutta-percha cone의 근관 내 적합도는 치근단 5mm의 근관면적에 대한 gutta-percha cone의 점유 면적비(%)로 하였다. .04 taper, 25번 크기의 근관에서는 F, MF 크기의 비표준화 cone이 표준화 cone과 Dia-Pro 180-.04$^{TM}$ 보다 우수한 근관적합도를 나타내었고(p<0.05), 30번 크기의 근관에서는 F, Dia-Pro ISO-.04$^{TM}$, FM 크기의 gutta-percha cone 모두 표준화 cone보다 우수한 근관적합도를 나타내었으나(p<0.05), 35번 크기의 근관에서는 모든 gutta-percha cone 사이에 유의한 차이를 나타내지 않았다(p>0.05) .06 taper, 25번 크기의 근관에서는 사용된 비표준화 cone 모두가 표준화 cone, Dia-Pro ISO-.06$^{TM}$ 보다 나은 근관적합도를 나타내었고(P<0.05), 30번 크기의 근관에서는 표준화 cone을 제외한 나머지 gutta-percha cone에서 유의한 차이를 발견할 수 없었다. 35번 크기의 근관에는 M 크기의 비표준화 cone이 가장 우수한 근관적합도를 보이고 있는 것으로 나타났으며, FM과 Dia-Pro ISO-.06$^{TM}$ 사이에서는 유의한 차이가 나타나지 않았다(p>0.05).
