조선 전기 대여진정책과 여진 귀화인 童淸禮

권영란(Kwon, Young-Ran) 역사실학회 2017 역사와실학 Vol.62 No.-

이 논문은 조선 전기 귀화인 童淸禮의 대여진 활동과 그것이 조선의 대여진 관계에서 차지하는 의미에 대해 검토한 것이다. 건국 초기 조선은 대내적 안정과 더불어 북쪽의 변방 안정이 매우 중요하였다. 이 때문에 조선은 북쪽 변방에 흩어져 살고 있던 여진을 藩籬로 인식하였고, 그들을 좀 더 효율적으로 통제하기 위하여 여진 귀화인을 적극적으로 활용하였다. 이들은 동류들을 회유하거나 여진의 형세를 살피기도 하고 노략해간 인구나 도망한 향화인을 쇄환하는 역할 등을 담당하였다. 동청례 가문은 이와 관련하여 여러 활동을 수행한 대표적 가문이었다. 이들은 조선 전기 여진정책이 북방의 상황에 따라 다변화하는 시점에서 항상 중요한 역할을 담당하였다. 특히 동청례는 선조들의 활약에 힘입어서 성종·연산군 대 활발한 활동을 펼친 인물이었다. 당시 建州三衛 추장들은 동청례 일족으로 구성되어 있었기 때문에 여진과의 관계에서 그의 교량적 역할은 큰 비중을 차지하였다. 뿐만 아니라 그는 변방의 울타리인 城底女眞의 동향까지도 정확하게파악하고 있었기 때문에 조선의 북방 안정에 크게 기여하였다. 그러나 동청례는 중종 3년(1508) ‘辛服義의 獄’에 연루되어 사망하였는데, 그의 사망 이후에는 여진과의 관계에서 교량적 역할을 수행할 인물이 거의 없었다. 이로 인해 조선은 건주삼위 뿐만 아니라 성저여진에 대해서도 조차 소통부재로 인해 효율적인 통제에 어려움을 겪었다. 따라서 조선과 여진 사이에서 향도적 역할을 주도적으로 수행한 동청례의 활동은 중요한 의미를 가진다. This study set out to investigate the activities of Dong Cheong-Rye(童淸禮) a naturalized person in the former half of Joseon, against Jurchen and review the meanings of his activities in Joseon"s relations with Jurchen. In the early days of its foundation, Joseon placed enormous importance on the stabilization of its northern frontier in addition to its domestic stabilization. Joseon thus regarded the Jurchens, who were scattered along the northern frontier, as the fence and made active use of Jurchen people that were naturalized into Joseon people to control them more efficiently. They conciliated their fellow Jurchens, monitored the situations of Jurchen, and repatriated the plundered population or escaping naturalized persons. The family of Dong Cheong-Rye was one of representative families that engaged in various activities in the concerned areas. Living in the frontier of Joseon, they always played crucial roles at a time when the government diversified its policies for Jurchen according to the situations of northern regions during the former half of Joseon. On the back of his ancestors" active roles, Dong Cheong-Rye did especially active activities during the reign of Kings Seongjong(成宗) and Yeonsangun(燕山君). Since the chiefs of Keonjusamwi(建州三衛) were from his kin at that time, he held a significant position as a bridge in Joseon"s relations with Jurchen. Furthermore, he followed even the trends of the Jurchens under the fortress(城底女眞) that was the fence in the frontier accurately, thus making considerable contributions to the stabilization of Joseon"s northern region. He was, however, involved in "Shin Bok-ui"s death in prison(辛服義의 獄)" in the third year(1508) of King Jungjong(中宗)"s rule and killed. Since his death, there were few figures that served as a core bridge in Joseon"s relations with Jurchen. As a result, Joseon suffered difficulties with controlling both Keonjusamwi and the Jurchens under the fortress efficiently due to the lack of communication. Those findings shed light on the important significance of activities of Dong Cheong-Rye that played initiative roles as a guide between Joseon and Jurchen.

Purpose: To verify the anti-microbiotic activity and to develop eco-friendly surface disinfectants using the Opuntia ficus-indica extract. Methods: The stem and fruits of the Opuntia cultivated in Jeju Island were extracted with hot water, 70% EtOH and 100% MeOH, respectively. To examine the antimicrobial activity of the extracts, gram positive bacteria (Bacillus subtilis, Staphylococcus aureus), gram negative bacteria (Escherichia coli, Salmonella typhimurium), yeast (Candida albicans), mold (Aspergillus flavus) and antibiotic resistant bacteria (E. coli, S. aureus) were measured to form a clear zone. Results: The antibacterial activity of the fruit extract was higher than that of the stem extract, and the antibacterial activity of the 100% MeOH (FM) extract and the 70% EtOH (FE) extract of the palm cactus fruit was suitable for the surface disinfectant overall, and clear-zone formed even at relatively low concentrations (250 mg/mL). The FM and FE have antibacterial activity against various bacteria, therefore they can be used as disinfectants. Conclusion: The antimicrobial activity of Opuntia ficus-indica extract from Jeju Island by stem and fruit was determined at relatively low concentrations (250 mg/mL). The Opuntia ficus-indica extract will be useful for surface disinfectants dissolving the patients’ bath, oral gargling, and powdered powder in water or ethanol in appropriate concentrations.

The purpose of this study is to examine the characteristics of negative architectural heritage and to argue for the a methodology differentiated from positive heritage. In addition, the limits of the current architectural heritage system are explored through the registered cultural heritage system. Negative architectural heritage is a media to leave to future generations the memories of the terrible history and the lessons learned from the history. However, the current system does not distinguish between negative heritage and positive heritage, there is a problem that the same heritage conservation and utilization decision-maker and valuation system are applied. It is expected that these problems can be solved through research on expanding the participants in decision-making, and methodologies for judging the value of negative heritage.

An acute fatal infectious disease in rabbits has been outbroken in Korea since 1985. This disease has been characterized as an acute hepatitis caused by viruses. However, viral pathogenesis in rabbit viral hepatitis leading to sudden death remain unclear. This report dealt with the electron microscopic findings on the spleen of experimentally infected rabbits, because spleen is one of the affected organs which have high titer of virus by a haemagglutination test. A typical crystalline array of virus was not found in the splenic cells of infected rabbits with acute hepatitis. Virus-like particles were seen within the phagosome of macrophages of the spleen. Ultrastructural changes in the spleen were severe with the lapse of time after inoculation. From these results, virus-like particles in the spleen were supposed to be phagocytosed by macrophage during viremia, while active replication of virus occurred in the liver. It was concluded that sudden death in this viral disease was caused by hepatic coma and/or circulatory disturbance.

This paper dealt with the clinical and pathological observations on the experimental rabbit viral hepatitis. Rabbits with 2-14 months of ages were intramuscularly inoculated with virus suspension. The results were summarized as follows. Ninety percents of experimental rabbits inoculated with virus died within 96 hours postinoculation. Common clinical signs were inappetence, increase in body temperature, depression, mild diarrhea and in three cases, bloody foam from nostrils was recognized. At necropsy, in most of the experimental cases, there were hyperemia or haemorrhages in many organs and pale liver. Intestinal catarrh and retention of turbid urine in urinary bladder were seen in some cases. Histopathologically, liver necrosis was found in all the cases died of this disease. However, there was a difference in the severity of hepatic necrosis. Haemorrhages were Iecognized in lungs, heart, liver, spleen, kidneys and thymus, in order. Liver necrosis was marked even in the cases with no haemorrhage. Perivascular cuffing in brain and catarrhal enteritis in small intestine were seen in many cases. From these results, consistent and primary lesion in this viral disease is hepatitis in susceptible rabbits. It was concluded that rabbit hepatitis virus might have the properties of hepatotropism and consequently induce peripheral necrosis in the liver leading to acute viremia with haemorrhages. 국내에서 발생된 토끼 virus성간염의 병리학적 소견을 명확히 규명하기 위하여 2~14개월령의 재래토끼에 간염에 이환된 토끼의 간조직 유제를 접종한후 임상 및 병리학적으로 관찰하였던 바 다음과 같은 결과를 얻었다. 접종한 30마리중 90%인 27마리가 감염되어 접종후 96시간이내에 폐사되었고 2~3월령 3두는 감염이 일어나지 않았다. 임상증상으로는 식욕부진, 체온상승, 연변 등이 나타났고 3두에서는 비강내로부터 혈액성 포말이 관찰되었다. 부검소견으로는 장기의 충출혈, 간장의 변성이 전예에서 관찰되었고 소장의 카타르성 장염과 방광내 혼탁한 뇨충만도 관찰되었다. 광학현미경적 소견으로는 간괴사가 정도의 차이가 있기는 하나 폐사된 27두 전예에서 관찰되었고, 출혈빈도는 폐가 가장 많았고 심장, 간장, 비장, 신장 및 흉선 순으로 나타났다. 한편 출혈이 관찰되지 않은 예에서도 간의 괴사소견은 현저하였다. 소장의 카타르성 장염과 뇌의 혈관주위 임파구 침윤도 관찰되었다. 이상의 결과를 종합해 볼 때 본 질병에서 출혈소견은 개체에 따라 변화가 심하였으나 중요한 소견은 간염으로 나타났고 원인 virus는 일차적으로 간에 친화성을 가지며 동시에 viremia를 일으켜 전신장기에 출혈을 야기하는 것으로 추정된다.

진효상(Hyo Sang Jin),권영란(Young Ran Kwon),윤영주(Yeong Ju Yun),이경자(Kyung Ja Lee) 한국식품영양과학회 2007 한국식품영양과학회지 Vol.36 No.12

전주지역에서 김장시기에 수거한 김치의 미생물 조성과 관능성적간의 상관성을 조사하여 다음의 결과를 얻었다. 김치는 21 표본 중 11 표본에서 L. mesenteroides가 8.31~11.27 logCFU/g의 범위에서 지배균으로, 16 표본에서 L. sakei가 7.97~10.57 logCFU/g의 범위에서 차지배균으로 나타났다. 김치의 관능성적은 총균수, 지배균수, 차지배균수, 균종수 등 계량적 특성에는 유의적 상관성이 없었다. 가장 맛이 좋은 김치 3종은 모두 지배균이 L. mesenteroides, 차지배균은 L. sakei인데 비해 가장 맛이 없는 김치 3종은 지배균에 L. sakei가 많아 김치의 맛은 주요 미생물의 균종의 조합과 관련이 있었다. 효모는 8표본에서 3.80~4.62 logCFU/g의 범위로 검출되었으며 모두 Saccharomyces servazzii로 동정되었다. 곰팡이는 전혀 검출되지 않았다. 효모 균수와 김치의 관능성적은 유의적 상관성이 없었다. The 21 Kimchi samples collected by a contest for the best Kimchi homemaker in Jeonju were analysed to find major microbial composition and the correlation between sensory scores and the microbial properties, which include total microbial numbers, dominant strain number, subdominant strain number, yeast strain numbers, and floral diversity. The most common microbial composition of the Kimchi samples was Leuconostoc mesenteroides as dominant strain, and Lactobacillus sakei as subdominant strain, the pattern of which was also observed in all three Kimchi samples with the highest sensory scores, but not in all three Kimchi samples with the lowest sensory scores. However none of the other examined properties showed any significant correlation to sensory scores. This result means that the taste of fermented Kimchi depends mainly on the composition of bacterial species and that of Leuconostoc mesenteroides as dominant strain and Lactobacillus sakei as subdominant strain is the best for good taste. Yeast strains were found in the range of 3.8~4.6 logCFU/g from 8 Kimchi samples and all the strains were identified to be Saccharomyces servazzii. However, fungi were not detected from any of the Kimchi. samples.

Negative heritage refers to cultural heritage that causes negative emotions and conflicts in the community depite having cultural heritage values. In Korea, after the 2000s, as ‘the registered cultural heritage’ was introduced and the importance of modern and contemporary heritage increased, negative heritage also began to change into an asset to be conserved and utilized rather than demolished. However, at the same time, conflicts expressed by negative emotions caused by negative heritage are also gradually increasing. In this study, by analyzing the conflict characteristics that occur in negative heritage in Korea through literature review and case study, implications that can contribute to future negative heritage conservation and utilization policies are derived.
