이번 실험은 차광조건하에서 생장조절제들이 한국잔디 ‘제니스’의 수평생장에 미치는 영향에 대하여 알아보기 위하여 수행하였다. 실험포지 잔디를 무차광, 47%와 77%의 차광조건 하에 flurprimidol(FP), paclobutrazol(PB), trinexapac-ethyl(TE) 세가지의 생장조절제를 각각 0.2, 0.4, and 0.8 ㎏ㆍ㏊?¹ FP, 0.16, 0.32, and 0.64 ㎏ㆍ㏊?¹ PB, 그리고 0.04, 0.08, and 0.16 ㎏ㆍ㏊?¹ (TE)씩 처리하였다. 한국잔디 ‘제니스’의 수평생장은 차광정도가 증가함에 따라 감소하였다. 무차광조건에서 0.2, 0.4 ㎏ㆍ㏊?¹ FP, and 0.16 ㎏ㆍ㏊?¹ PB를 처리한 결과 포복경의 전체 길이와 수가 대조구에 비하여 2배 정도 증가하였다. 77% 차광조건에서는 0.8 ㎏ㆍ㏊?¹ FP를 처리하였을 경우 포복경의 수는 170%, 전체 포복경의 길이는 140%증가하였다. 분얼경수는 무차광조건에서는 0.08 ㎏ㆍ㏊?¹ TE를, 77% 차광조건에서는 0.16 ㎏ㆍ㏊?¹ TE를 처리하였을 경우 각각 40%, 72%의 증가를 보였다. 전체 당함량은 0.8 ㎏ㆍ㏊?¹ FP와 0.16 ㎏ㆍ㏊?¹ TE 처리구에서 대조구 대비 약 50%의 증가를 보였으며, 특이한 것은 비구조성 탄수화물이 잔디의 잎에서 기는 줄기로 이동하는 것으로 나타나, 이는 한국잔디의 수평생장을 증가시켜 회복속도를 높이는데 도움이 될 것으로 판단된다. 이상의 결과를 통하여 그늘상태에서의 한국잔디의 도장과 줄기밀도의 감소를 방지시키고, 또한 포복경의 발달을 촉진시켜 회복력을 높이기 위하여 생장조절제의 처리가 매우 효과적인 것인 것으로 판단되었다. This study was conducted to examine the effects of plant growth regulators (PGRs) on the lateral stem growth, and the change of total nonstructural carbohydrate (TNC) status of ‘Zenith’ zoysiagrass under shaded conditions. Well-established turf was subjected to a full sun, 47%, and 77% shade in a field study. Three different rates of flurprimidol (FP: 0.2, 0.4, and 0.8 ㎏ㆍ㏊?¹), paclobutrazol (PB: 0.16, 0.32, and 0.64 ㎏ㆍ㏊?¹), and trinexapac-ethyl (TE: 0.04, 0.08, and 0.16 ㎏ㆍ㏊-1) were applied. Lateral development of ‘Zenith’ zoysiagrass decreased with increasing shade levels. However, compared with control plots, total stolon length and stolon number increased two fold at 0.2, 0.4 ㎏ㆍ㏊?¹ FP, and 0.16 ㎏ㆍ㏊-1 PB under full sun. Under 77% shading, stolon number increased by 170% and total stolon length increased by 140% at 0.8 ㎏ㆍ㏊?¹ FP. Tiller number increased by 40% at 0.08 ㎏ㆍ㏊?¹ TE under full sun, and by 72% at 0.16 ㎏ㆍ㏊?¹ TE under 77% shading. The TNC contents of turfgrass treated with 0.8 ㎏ㆍ㏊?¹ FP and 0.16 ㎏ㆍ㏊?¹ TE increased by 50% as compared with control. Remarkably, nonstructural carbohydrates (NC) partitioning was enhanced by PGRs from leaf tissue to lateral stem tissue, which increased lateral development and may have contributed to recuperative rate. These results suggested that treatments of proper rate of PGRs could enhance the recuperative rate of ‘Zenith’ zoysiagrass by increasing lateral stem growth especially in shaded conditions.

The bleaching of discolored nonvital teeth is conservative treatement that satisfy the cosmetic desire. The most common method for this treatement, walking bleaching, is using 30% hydrogen peroxide and sodium perborate. Many alternatives are suggested for preventing the external cervical root resorption that is the common complication of the nonvital teeth bleaching with 30% hydrogen peroxide. The same extent of oxidation reactions as that resulted by the bleaching with the application of 30% hydrogen peroxide and sodium perborate can also be acquired more safely by materials that contain 10% carbamide peroxide, used primarily for the bleaching of vital teeth. Therefore, this study was performed to evaluate the efficacy of 10% and 15% carbamide peroxide bleaching gel in nonvatal teeth bleaching. The internal bleaching of intentionally discolored teeth was performed in vitro with 10% carbamide peroxide (Group 1), 15% carbamide peroxide (Group 2), mixture of distilled water and sodium perborate (Group 3), and mixture of 30% hydrogen peroxide and sodium perborate (Group 4). The bleaching materials were refreshed following 3, 6, 9 and 12 days. To evaluate the bleaching effect, the color change of the crowns was measured at 1, 2, 3, 4, 7 and 15 days of bleaching using the colorimeter. The results were as follows : 1. L^* and ΔE^* values were increased with time in all bleaching agents(p<0.01). 2. There was no significant difference in L^* and ΔE^* value among bleaching agents. 3. Δ^* value higher than 3 was shown after 3 days of bleaching with 10% carbamide peroxide gel, 1 day with 15% carbamide peroxide gel, 4 days with mixture sodium perborate and distilled water and 4 days with mixture sodium perborate and 30% hydrogen peroxide, respectively. These results revealed that the use of 10% and 15% carbamide peroxide bleaching gel in non-vital teeth bleaching is as effective as mixture of distilled water and sodium perborate and mixture of 30% hydrogen peroxide and sodium perborate. Accordingly, carbamide peroxide could be used clinically to bleach discolored non-vital teeth.

孤山 尹善道의 삶과 文學 小考

오선주(Oh Sun-Ju) 한국시조학회 2005 시조학논총 Vol.23 No.-

이 글은 강호자연과 정치현실을 반복적으로 넘나든 孤山 尹善道의 삶과 그의 문학에 대해서 고찰한 것이다. 특히 강호와 조정의 두 현실에 대해서 어떤 인식 양상을 보이며, 작품에 어떻게 투영되어 나타나는가에 초점을 두어 살폈다. 그리고 이를 바탕으로 그의 문학관을 검토하였다. 먼저 정치적 시련의 시초가 된 상소문을 통해서 정치현실과 타협하지 않는 직선적 성격과 이에 내재된 강한 정치적 성향을 지적하고, 이를 출처관과 관련지어 논의하여 재설명하였다. 이에 두 면모는 각각 대결의식과 두 현실을 상황에 따라 넘나드는 모습으로 투영됨을 확인하였다. 그리고 윤선도가 주로 기거한 金鎖洞의 산수 경관을 술회한 〈金鎖洞記〉의 내용을 분석하여 자연관의 총체가 ‘會心’으로 집약됨을 밝혔다. 이 회심에는 강호 생활에 대한 만족과 그에 따른 윤리의식이 내포되어 있는데, 이것이 그대로 작품에 투영되고 있다. 끝으로 단편적으로 문학에 대해 언급한 글을 살펴보고, 자연의 법칙과 윤리의식을 작품에 담아내야 한다는 것이 윤선도의 문학관이라고 규정하였다. This study is about literature of Gosan Yun Sun-do(孤山 尹善道) and his life that haunted Gang-ho(江湖) natures and political realities repeatedly. Especially, it considers what aspect of cognition he had about two realities. Gang-ho(江湖) and the Imperial Court(朝廷) and how it throws image on his works. And through these. it is examined what his viewpoint of literature is. First of all, through a memorial to the Throne that put him in first political trial, we can know that he was so strict that he didn't compromise with political realities and at the same time, he has a strong political inclination hidden behind his character. These two aspects are reflected on his works as his confrontation will and his agony between the two realities two realities. And through analysing the contents of 〈金鎖洞記〉 that recollect landscapes of 金鎖洞 where Yun Sun-do mostly stayed, it can be found that his total viewpoints of nature is complacency. This complacency including the satisfaction of Gang-he life and his ethics is intactly reflected on his works. Finally, it is dearly revealed that he tried to embody the principle of nature and ethics in his literary works and his reference to the literary as well.

백서에서 Depulpin®과 Formocresol에 대한 치수와 치근단 조직의 반응

문형인,김선호,황윤찬,오병주,황인남,김선헌,정선와,윤창,오원만 大韓齒科保存學會 2002 Restorative Dentistry & Endodontics Vol.27 No.4

One fifth dilution of formocresol is usually for pulpotomy of the primary teeth and emergency pulpotomy of the permanent teeth. However, the use of formaldehyde has been subjected to criticism because it may be absorbed into the blood stream and become distributed systemically, it may also alter the pulp tissue rendering it immumologically active, and have carcinogenic potential. Recently Depulpin®(VoCo., Germany) gains popularity as a devitalizing agent during root canal therapy in spite of high concentration of 49% paraformaldehyde because it facilitate devitalization of pulp and make root canal therapy easier. But there have been not enough publications about the reaction of pulp and periapical tissue caused by Depulpin. This study was performed to evaluate the histological changes in pulp and periapical tissue of rats after pulpotomy using formocresol and Depulpin and to elucidate the toxic effects of these agents. Thirty six Sprague-Dawley rats were anesthetized by intraperitoneal injection of ketamine. Maxillary first molar teeth were used for pulpotomy with formocresol and Depulpin. Rats were sacrificed after 2 days, 4 days, 1 week, 2 weeks, 3 weeks and 4 weeks respectively. Specimens were histologically observed by light microscope changes in pulp and periapical tissue. The obtained results were as follows. 1. Formocresol group A zone of fixed tissue, in which odontoblasts could clearly be defined, was present directly underneath the pulpotomy dressing in almost all teeth of this group. This was followed by an area of necrotic tissue which resembled dried out fibrous tissue with no cellular detail except some pyknotic nuclei. In the specimens of after 2 days, 4 days, 1 week, 2 weeks in which vital tissue was present. it was separated from the fibrous area by a zone of inflammation. In the specimens of after 3 weeks and after 4 weeks, inflammatory infiltrate was in the periodontal ligament adjacent to the apical foramina of the teeth. 2. Depulpin® group The area of necrotic tissue which had no cells and fibers , was present adjacent to the dressing. This was followed by dried out fibrous tissue with no cellular details except some pyknotic nucleli. A short stump of vital pulp with odontoblasts was present at the end of the canal after 2 days. Inflammatory infiltrate was in the periodontal ligament after 4 days and after 1week. Severe root resorption and necrosis of periapical tissue opposite the root resorption site were defined after 2 weeks and after 3 weeks. Periapical lesion which consist of necrotic tissue surrounded by a fibrous connective wall. was found after 4 weeks. The results indicated that Depulpin can cause more adverse reaction to the dental pulp and periapical tissue than formocresol, and further studies are needed for its clinical use with safety.

강현모,이정은,장필순,이연선,권선중,안진영,정성수,김주옥,김선영 충남대학교 암연구소 2006 암연구소 업적집 Vol.5 No.-

Background : The survival benefit associated with first-line chemotherapy in lung cancer has led to the need for second -line chemotherapy, for which Docetaxel (Taxotere^(?)) has proven efficacy in both settings. This study evaluated the safety and efficacy of docetaxel in patients with non-small cell lung cancer who had failed first-line platinum-based chemotherapy. Methods : Thirty one patients with non-small-cell lung cancer, who had failed first line platinum-based chemotherapy, between March 1999 and August 2003, were enrolled in this study. Patients received intravenous docetaxel, either 75 mg/㎡ or 100 mg/㎡, with routine premedication every three weeks. Results : Fourteen patients (45.2%) had a partial response. The median survival and progression- free survival times were 12.5 months (95% CI 7.3-17.6) and 3.0 months (95% CI 1.6-4.5), respectively. This study showed 2 factors gave different survival benefits; the age (< 60 years: 20.1 months vs. > 60 years: 6.6 months, p=0.0105) and the histological type (adenocarcinoma: 25.6 months vs. others: 7.9 months, p=0.0055). The predominant toxicity was neutropenia, which occurred as WHO grade 3 or 4 in 38.7 % of patients. One treatment related death was also reported. Non-hematological toxicity was minor and easily controlled. There were no significant statistical differences in the survival benefit and toxicity between the two doses. Conclusion : Docetaxel, as second-line monotherapy, was well tolerated and effective in patients with non-small-cell lung cancer who failed first line platinum -based chemotherapy.

인구재분배(Population Redistribution) 정책에 대하여

권태환(Kwon Tae Whan),Yoon Jong Ju(토론자),Kim Sun Oong(토론자) 한국인구학회 1979 한국인구학 Vol.2 No.1

The population redistribution policy of Korea may be summarized as follows: 1. Decentralization of industries. 2. Construction of new towns including development of temporary administrative city. 3. Development of growth poles. 1. The decentralization of industries as a means of population dispersion has been widely debated and proven to be effective in many other countries. As pointed out before, the decentralization of industries has a widely varying degree of impacts on population dispersion according to the nature of industrial re-location programs. 2. The construction of new towns and the development of administrative cities have proven to be effective as a population redistribution policy in socialist countries and Japan. These example do not guarantee success if such policy is applied in Korea. The success depends on the amount of the concomitant investment to be made in educational and cultural facilities in the new towns. 3. The development of growth poles as a means of population dispersion has not proved to be successful in the Eastern Block Countries and Japan. However, this may be the optimal means of dispersion population for Korea when one considers her present level of economic development. (1) The development of farming sector and (2) the slow-down of farming population exodus into cities should be considered as a viable alternative program for population dispersion policy. We cannot cite many examples in other countries where the development and improvement of farming sector has been successful as a means of dispersing population. However, Japan's development of her northern areas has not only improved the standard of living in Hokkaido but also contributed to population dispersion. Discussant Yoon, Jong Ju: Population movements in Korea have resulted in the concentration of people in cities and the reduction of farming households. In the Sixties, the population of the nation converged into Seoul. As a result, the population dispersion policy emphasized the "slowing-down" of the population movements in to Seoul. This policy has shown some success in that the rate of population growth in Seoul has decreased since 1970 and the more so since 1975. This phenomenon, however, is confined to the city of Seoul. The surrounding areas have shown an increasing rate of population growth. The above indicates that population policy and population dispersion program should be conducted with long-range planning, if they were to be successful. However, such has not been the case. It should also be pointed out that population policy should be a comprepensive program encompassing population, economic and social aspects. Korean population policy has not been such comprehensive program. The population policy in the Eighties should not confine itself in decreasing the rate of population growth. Instead, it should focus on improving the quality of population and thereby, increasing the manpower of high quality. In order to carry out such policy, investment should be made to improve the data on population, in particular, on children. Discussant Kim, Sun Dong: Korean population policy does not possess foresight and is segmented without a clearly formulated long range goal. One inevitable and undeniable fact appears to be that three quarters of the nation's population will eventually settle in urban cities. There are many problems associated with the population concentration in the urban areas. First, there exist the well-known problems of environments and traffic congestions in urban centers. Second, there are the problems associated with the effective utilization of the nation's land and natural resources. Third, there are the geopolitical issues related to the national defense and security. Although we recognize these problems, it should be also pointed out that population concentration in cities is an inevitable result and cause of economic development.<
