논문 : 동북아지역(東北亞地域)에서의 다뉴경(多뉴鏡) 부장묘(副葬墓)의 전개(展開)

이청규 ( Chung Kyu Lee ) 단국사학회 2012 史學志 Vol.44 No.-

청동기는 생업도구의 수준에서 벗어나 전쟁무기와 종교의기로 제작·보급되었다. 이논문은 종교의기이자 무구(巫具)로서 제사장들이 보유했던 청동거울, 그 가운데서도 다뉴경을 중심으로 다뉴경이 부장된 무덤들의 역사문화적 의미를 고찰한다. 다뉴경은 대릉하유역부터 한반도를 거쳐 일본 구주(九州)지역에 이르는 범(汎) 십이대영 자문화권(十二臺營子文化圈)을 나타내는 유물이다. 다뉴경 부장묘는 이 문화권에 속한 고조선, 부여, 한 왜(倭)의 범주에 속하는 소국(小國)들의 수장들의 무덤으로서, 다뉴경뿐만 아니라 다른 청동기 및 토기부장품들이 부장되어 있다. 이 부장품들은 당시의 chiefdom 사회의 수장들을 중심으로 한 정치상황뿐만 아니라 범 대영자문화권 내의 기술교류를 반영한다. 다뉴경은 중국 동북지역에서 한반도와 일본열도에 걸쳐 당시 엘리트들이 제사장의 신분과 지위를 과시하는 위세품인데, 전파과정에 따라 대릉하지역의 A형 다뉴경, 요동과 길림지역의 B형 다뉴경, 한반도 서남부와 일본 구주지역의 C형 다뉴경으로 발전되어갔다. A형 다뉴경으로부터 B형 다뉴경의 등장은 연(燕)나라의 동진으로 고조선의 강역이 이동한 것에 기인한다. C형 다뉴경은 중국 동북지역에서는 발견되지 않고 한반도 서북한과 서남한 지역, 일본 구주(九州)지역에서 발견된다. 이는 다뉴경을 최고 위세품으로 채용하는 계층이 상위급 수장(首長)에서 차상급 이하의 엘리트로 내려갔음과 일본 구주 지역의 소국들이 한반도 서남부지역의 마한(馬韓)지역과 교류하고 있었음을 보여준다. The geometric-design bronze mirrors of which numbers about 80, are assumed to be as ritual tools and political symbols of priest-king during the 8th~2nd century BCE. Those are classified into three types, that are A, B, and C, and each of them is assumed to be made and used in 800~400BCE, 400~200BCE, and 200~50BCE. The distributional range of three types were changed under the historical conditions, which includes Yen(燕)`s advance toward the northeastern China and Wiman(衛滿) becoming a king of Gojoseon(古朝鮮). The first A type mirrors were distributed mainly in northeastern China, B type ones in the geographical range from northeastern China to the Korean peninsular, and C type ones from the Korean peninsular to the Japanese archipelago. The size and numbers of mirrors are reflective of the social position of the person with whom are buried in the grave, and so the graves with mirrors in each type are those of the most unfluential leaders of ``Kuk(國)``―the political and regional groups at the time. In A type mirror stage, the graves with most abundant artefacts are located in Liaoning pronince(遼寧省); the graves with most abundant artefacts in B type mirror stage are in Chung-nam(忠南) province; and the graves with C type mirrors in Cheon-nam(全南) province. Each region with those burials was the trade-center in Korea connecting China and Japan, and is assumed to be the location of the most influential ``Kuk(國)`` in old Korea.

Crohn`s disease is a chronic inflammatory bowel disease that can involve the whole gastrointestinal tract. The orofacial manifestation of Crohn`s disease, which is rare, can develop irrespective of intestinal involvement. These orofacial lesions are often misdiagnosed as simple oral ulcers. Corticosteroids are the mainstay of therapy for orofacial Crohn`s disease. However, infliximab, the chimeric monoclonal antibody to tumor necrosis factor-α, is now considered as a primary treatment because of the disease`s relatively high rate of steroid resistance. We present a case of deep oral ulcer and periorbital swelling in a 65-year-old woman. She was diagnosed with intestinal Crohn`s disease 7 years ago, which was in remission after treatment with an immunosuppressive agent (azathioprine). The patient was given the diagnosed with orofacial Crohn`s disease and successfully treated with infliximab. (Korean J Gastroenterol 2012;59:437-440)

최근접 Clustering 방법을 이용한 비디오 스토리 분할

이해만,정규식 崇實大學校 2000 論文集 Vol.30 No.1

We are approaching to an age of mobile multimedia information service which allows mobile network appliances to exchange multimedia information efficiently and effectively. As a core technology for the service, multimedia transcoding which transforms multimedia information to be suited for the appliance environment will be needed. In dealing with video transcoding, we need a good method of video representation for efficient storage and retrieval. One way to do so is to represent a video in a hierarchy of three levels; Frame Shot & Story. In this thesis, we propose a method of story segmentation by joining the neighbor shots, assuming that a video is already segmented into a set of shots. In the proposed method, firstly, we extract a representative (key) frame from each shot by considering its motion information and secondly extract CCV(Color Coherence Vector) features from the extrarted key frame as a visual feature. Thirdly, we apply a nearest neighbor clustering method to the key frames using two measures of visual similarity and temporal similarity. Using clustering results and story repetition property, we spit and merge video shots to make a set of stories. We implement the proposed method using Visual C++ in a IBM PC and perform experiments using movie videos. Experimental results show the effectiveness of the proposed method.

Facial spasm is the most common in middle aged women, which is a distressing condition characterized by involuntary, intermittent, unilateral twitching of the muscles innervated by the facial nerve. There are various treatments for facial spam, such as neurovascular decompression, local injection of botulinum, facial nerve compression at stylomastoid foramen and facial nerve block with O'Brien method. There are the same clinical problems associated with the reported procedure in pain clinic, such as severe pain and recurrence of spasm. In this paper, we report the modified facial nerve block using electric nerve stimulator at the stylomastoid foramen. This new technique will be able to reduce the pain and the discomfort during facial nerve block, and reduced the recurrence of facial spasm.

光令里와 郭支里 遺蹟·遺物의 比較 : 濟州島 先史文化에 對한 考古學的 硏究 Culture in 'Mumun T'ogi' Period

李淸圭,金宗業 제주대학교 1985 논문집 Vol.22 No.2

Ⅰ. Both of Kwanyoˇng and Kwakchi sites locate in the northwestern area of Cheju Island, the first is noted for the group of dolmens, the second for the shell-mound in prehistoric period. Two sites belong to the thick soiled area in the vicinity of sea-shore,have a big stream, and so the more advantagable places for cultivation, domestication than the other spots in Cheju Island. But the geological environments of the two are a little different from one another Kwanyoˇng site in the hilly land 70-90M above the sea and the center of it 3kM distant from it, and Kwakchi In the lower land 30M altitude and 0.7KM from the sea-shore. Ⅱ. Archaeological data of Kwanyoˇng site, which are collected through surface-survey method, informs the following facts : (1) 'Mumun T'ogi' or 'plain coarse potteries' are widely prevalent and 'Kimhae potteries' also used ; but stonewares of three kingdoms period are not discovered ; that means Kwanyoˇng culture began around B.C. 1C. and did not continue after A.D. 3-4C, three-kingdoms period. (2) There are many stone-made tools and most of them are classified into two groups ; the wood-cutting or soil-digging tools such as axe, plane, adze and the grain-grinding tools such as pestle, mano and saddle quern. But fishing and animal hunting tools are scarcely discovered. This suggests that fishing and hunting practices were less prevailed than the cultivation-dryfield farming at the Kwanyoˇng site. Ⅲ. (1) Kwakchi culture were clarified with a method of stratigraphical excavation of the shell-mound and can be divided into the following three stages ; ①rim-perforated Mumun T'ogi stage ②Mumun T'ogi with shallow rim(A)·Kimhae pottery stage ③Mumun T'ogi with shallow rim(B)·Three Kingdoms stone-ware stage. The first stage dates from B.C. 3~4C, the second from B.C. 1C, and the last around A.D 3~4C, and so Kwakchi culture began earlier and continued later than Kwanyoˇng culture. (2) We cannot say positively with lack of enough data, but only guess that fishing and hunting are not prevalent more than farming in the first stage, because the cultural layers of this stage in the shell-mound do not contain animal bones and shells. Most of stone-tools in the second stage are grain-grinding tools and fishing tools, and this reflects farming and fishing are prevalent. Some Iron-made artefacts are also discovered in the layers of this stage, and on the basis of these advanced metal tools·fishing and hunting are more efficient and prevalent than the preceeding stage. Therefore it is a natural result that we can find many aninal bones and shells in those cultural layers. In the last stage, Mumun Tog'i are much improved and stonewares are also made for a variety of uses. A few stone-made tools are discovered, with most of them grain·grinding tools and the more improved iron-tools also discovered in this stage. Ⅳ. Therefore it is understood that the Kwakchi site had been habitated by peoples longer than the Kwanyoˇng site , because the natural condition of the first is more advantagable than that of the second for the habitation.

Vincristine Sulfate가 백서 척수내 신경원의 Acetylcholinesterase 활성에 미치는 영향

이규식,이군자,정호삼,김승현,백태경 漢陽大學校 環境科學硏究所 1992 環境科學論文集 Vol.13 No.-

Vincristine은 협죽도과에 속하는 열대식물인 Madagascum periwinkle에서 추출한 천연 alkaloid계 항암제로서 암세포의 미소관 형성을 억제하고 미소관을 파괴하며 또한 핵산 및 단백질합성을 방해하여 암세포의 증식을 억제하므로 현재 백혈병 및 임파종등 혈액종양과 여러 충실성종양의 치료에 유용하게 사용된다. 그러나 다른 항암제와 마찬가지로 암세포에만 특이하게 작용하지 않고 정상세포에도 손상을 야기하므로 vincristinc을 투여받은 암환자에서 혈액독작용, 소화기장애, 피부장애 및 신경독작용등 여러 부작용이 유발되고 특히 신경독 작용은 vincristine을 사용을 제한하는 가장 심각한 장애로 알려져있다. 저자는 백서에 vincristine을 투여하면 vincristine이 실험동물의 척수내 신경원에 손상을 야기하여 척수내 신경원의 acetylcholinesterase활성에 변화가 초래될 것으로 사료되어 본 실험을 시도하였다. 실험동물로는 체중 200gm내외의 Wistar계의 웅성 백서 35마리를 사용하여 백서 체중 kg당 0.5mg의 vincristine sulfate(Abic Ltd.) 0.2cc를 1일 1회씩 5일간 복강내로 주사하였고 정상대조군 백서에는 동량의 생리적 식염수를 같은 방법으로 투여하였다. 실험동물은 최종 주사후 24시간 및 72시간 경과 후에 후두부 강타로 도살하고 10% neutral buffered formaline으로 관류시킨 후 육안으로 해부하여 척수를 절취하고 10% neutral buffered formaline에 4℃에서 18시간 고정후 일부 조직은 paraffin에 포매하여 Nissl체를 관찰하기 위한 cresyl violet염색을 시행하고, 일부조직은 -20℃로 조절된 cryostat로 두께 10㎛의 동결절편을 제작하여 Gredtzoff(1959)의 방법에 따라 acetyl-cholinesterase활성을 관찰하기 위한 조직화학적 처리를 한 후 광학현미경으로 관찰하여 다음과 같은 결과를 얻었다. 1. Vincristine투여군 백서의 척수내 체성운동신경원 및 내장성운동신경원에 chromatolysis가 유발되었으며, 소신경원의 수와 cresyl violet 에 대한 염색성이 감소되었다. 2. Vincristine투여군 백서 척수경부의 acetylcholinesterase활성은 1일 경과군의 복측각내 체성 운동신경원에서는 강한 양성반응을 나타내었고 배측각에서는 약한 양성반응을 나타내었으며 중간부에서는 미약한 양성반응을 나타내었으나 3일 경과군의 복측각내 체성운동신경원과 배측각내 교양질부에서는 중등도 양성반응을 나타내었으며 중간부에서는 미약한 양성반응을 나타내었다. 3. Vincristine투여군 백서 척수흉부의 acetylcholinesterase활성은 1일 경과군의 복측각내 체성운동신경원과 외측각내 내장성운동신경원에서는 약한 혹은 중등도 양성반응을 나타내었고 배측각에서는 약한 양성반응을 나타내었으며 척수수질의 중간부에서는 미약한 양성반응을 나타내었으나, 3일 경과군의 복측각내 체성운동신경원에서는 중등도 양성반응을 나타내었고 외측각내 내장성 운동신경원에서는 강한 양성반응을 나타내었으며 배측각내 교양질부에서는 중등도 양성반응을 나타내었으나 배측각의 나머지 부분에서는 약한 양성반응을 나타내었고 척수수질의 중간부에서는 미약한 혹은 약한 양성반응을 나타냈었다. 4. Vincristine 투여군 백서 척수요부의 acetylcholinesterase활성은 1일 경과군의 복측각내 체성운동신경원에서는 중등도 혹은 강한 양성반응을 나타내었고 배측각의 교양질부와 Lamina Ⅳ에서는 중등도 양성반응을 나타내었으며 배측각의 나머지 부분은 약한 양성반응을 나타내었고 척수수질의 중간부에서는 미약한 양성반응을 나타내었으나, 3일경과군의 복측각내 체성운동 신경원에서는 약한 혹은 중등도 양성반응을 나타내었고 배측각내 교양빌부와 Lamina Ⅳ에서는 약한 양성반응을 나타내었으며 척수수질의 중간부에서는 미약한 혹은 약한 양성반응을 나타내었다. 이상의 소견을 종합한 바, vincristine은 백서 척수내 신경원에 세포독으로 작용하여 신경원 손상을 초래하고 신경원의 acetylchlinesterase활성을 억제 하나, 이러한 손상은 시간이 경과함에 따라 일부 회복되는 것으로 사료된다. Vincristine, one vinca alkaloids, is widely used for chemotherapy of a variety of malignancy. The mechanism of anticancerous activity of this agent is based on inhibition of mitosis by interference with development of microtuble, of syntheses of nucleic acid and protein, and of destruction of cytoplasic membrane and microtubule. However, these inhibitory effects on cancer cell proliferation are non-specific, so clinical use of vincristine is frequently limited due to its toxic effects on the hematopoietic and nervous system especially. The author had undertaken this study to pursue the effect of vincristine on the nuerons in rat spinal cord histolgically and histochemically. Totals of 35 healthy male Wistar stain albino rats, weighing about 200 gm, were used as experimental animals. The experimental animals were divided into normal control and vincristine treated groups, and then vincristine treated rats were subdivided into 24 hours and 72hours groups by time passage. All vincristine treated rats were abministrated intraperitoreally with 0.5mg of vincristine per kg of rat body weight diluted in 0.2cc of normal saline for 5 days and rats of vincristine treated group were sacrificed by occipital blow at 24 hours and 72 hours after administration and then perfused by 10% neutral buffered formaline. The spedimen, spinal cord was collected and them fixed with 10% neutral buffered formaline during 18 hours at 4℃. For observing the histological change, cresyl violet stain was performed by routine pareffin method, and for histochemical study of acetylcholinesterase, frozen sedtions of 10 ㎛ in thickness were treated with Gerebtwoff method(1959). The results obtained were as follows : 1. In vincristine treated rat, a part of the somatic and visceral motor neurons were brought on chromatolysis. And the numer and the stain activities of small neurons were decreased in cresyl violet stain. 2. The activities of acetylcholinesterase of cervical segment in vincristine treated rat spinal cord were strongly positive at somatic motor meuron, weakly positive at dorsal horn and tracely positive at intermediate zone in 1 day passed group after the final administration, and moderately positive at somatic motor neuron and substantia gelatinosa, weakly positive at remainder of dorsal horn and tracely positive at intermediate zone in 3 days passed group. 3. The activities of acetylcholinesterase of thoracic segment in vincristine treated rat spinal cord weakly or moderately positive at somatic and visceral motor neurons, weakly positive at dorsal horn and tracely positive at intermdeiate zone in 1 day passed group after the final administration, and moderately positive at somatic motor mourons, strongly positive at visceral motor meurons, moderately positive in substantia gelatinosa, weakly positive at remainder of dorsal horn and tracely positive at intermediate zone in 3 days passed group. 4. The activities of acetylcholinesterase of lumbar segment in vincristine treated rat spinal cord were moderately or strong positive at somatic motor meurons, weakly positive at substantia gelatinosa and lamina Ⅳ, weakly positive at remainder of dorsal horn and tracely positive at intermediate zone in 1 day pssed group after the final administration, weakly or moderately positive at somatic motor neurons, weakly positive at sugstantia gelationsa and lamia Ⅳ and tracely or weakly positive at remainder of spinal medulla in 3 days passed group. It is consequently suggested that vincristine would induce the degeneration of neurons and inhibit acetylcholinesterase activity resulting from its neurotoxic effects on neurons in spinal cord of albino rats, but this damage would partially recover by time passage.

考古學을 통해 본 琉球와 주변지역과의 교류

李淸圭 서울대학교 비교문화연구소 2000 비교문화연구 Vol.6 No.1

Ryukyu Islands is divided into three sub-regions, the north include Tane and Yaku Islands, the second Amami and Okinawa Islands, and the last Miyako and Yayeyama Islands. The Chronological Systems of Archaeological Culture in these Islands have been suggested by some Scholors, among which Takemiya's System is accepted as the most appropriate one. Takemiya suggested three-period system, the first shellmound period corresponding to Jomon age of Japan mainland, the second shellmound period the Yayoi Age, and Kusuku period the Kofun and Heiyan Age. Some Jomon and Yaoi culture of Kyushu were imported in these Islands, but the rice cultivation and metallurgy of Yayoi Age seems not to be imported in the first shellmound period. According to Kinoshita's study on shell-made artifacts, the trade of Ryukyu Islands between Kyushu Island were executed by not Ryuku Islanders but North Kyushu People. Kofun style tombs similar to those of Kyushu were not discovered in these Islands in second shellmound period. There are some archaeolgical data in this period, for example Chinese Tang Dynasty coins, suggests that Ryukyu Island functioned as the intermediate trade place between China and Japan. The cultural interaction between Ryukyu Islands and the Korean Peninsula can be identified by archaeolgical data in the Kusuku and post-Kusuku Period. Those data are the roof tiles with inscription of Korean craftsman and Punch'ong Porcelain in 14~15th Cent.
