Soluble poly(dimethyl-co-diphenylsilane)copolymer,[(SiMe₂)x(SiPh₂)1-x]n where x=0.5 to 0.9., was synthesized by condensation polymerization of dimethyldichlorosilane and diphenyldichlorosilane in xylene. In the TG analysis of the copolymer, weight loss started at 170℃ and the weight residue at 1000℃ was 32%. The copolymer was stabilized by thermal oxidation at 80 to 110℃ for 5 hr. in air, and its thermal stability increased as the temperature increased. The copolymer heat treated above 700℃ showed no organic bonds of C-H and Si-CH₃. while Si-C, and Si-O large bonds were observed. Amorphous SiC was obtained by pyrolysis at 1000℃ and β-SiC at 1200 to 1400℃, in which a better crystallinity of β-SiC was observed at a higher temperature.

The project of desalinization in the new reclaimed land should be executed above all, because the damage of salinity in the paddy fields is due to the excess of salinity. Open ditch one of the most important methods of desalinization for expulsion of salinity by the irrigation water as well as decreasing the ground Water contained salinity. In this research, the effects of open ditch and of desalinization by irrigation water during the period of paddy plants growing, and changes of saline content in reclaimed land which is located in Kang-Hwa-Goon, Kyung-Ki-Do, were investigated. The results obtained in this research are summarized as follows: 1. The depth of saline expulsion by supplying of irrigation water was approximately 30cm to 50cm under the ground surface, but saline expulsion was hardly done in case of the depth which is deeper than the above mentioned, because the moisture and saline content hardly change in such a condition. 2. Infiltration speed of the Horizontal drainage was more rapid than that of vertical drainage in soil of Kang-Hwa reclaimed land. 3. In open ditch, we could make a good condition for the growth of rice plants, because the desalinization was not only rapid but also effective up to the subsoil layer. 4. The reasonable interval of open ditch was about 18m, and we could set limits approximately 30cm to 90cm in the depth of open ditch. 5. Saline changes of the soil in the reclaimed land was sensitive to weather condition and discharge of irrigation water, and changes of the monthly saline content was extreme in case of drying seasons and non-supplying of irrigation water, and saline content of surface layer seemed to be higher than that of subsoil. 6. The saline content of soil and the rate of disalinization showed a tendency to decrease according to cultivating years of rice plants. Rice plants was not nipped by salinity after 3 years cultivating in the conditin of open ditch by 18m iterval on the new reclaimed land.

Hyun-jee Kang and Myungki Oh. 2018. A Study on Joke Misinterpretation in L2 Settings: Viewed from The Benign-Violation Theory. Studies in Modern Grammar 99, 161-176. This paper examines cases in which Korean college students might misinterpret superiority, incongruity, and sarcastic English jokes. In parallel the writer tries to bring to light possible background reasons for their misinterpretation from the perspective of the Benign-Violation Theory’ concepts of norm violation, commitment, and psychological distance. Arguably Korean college students are likely to misinterpret English humor codes influenced by their ingrained belief system of strict moral standard as well as insufficient exposure to particular genres of English jokes.

오음(吳音) 일본전파설과 관련된 신라 김예신(金禮信)에 대한 논의

강대현 ( Kang Dae Hyun ) 한국사상사학회 2015 韓國思想史學 Vol.0 No.51

고대일본의 오음(吳音) 한음(漢音)은 중국 한자음의 발음양상에 대한 개념적 정의이다. 이러한 오음의 일본전파에 큰 영향을 준 고대한국인이 일본의 사료와 실담장에 등장하고 있다. 그들이 백제의 비구니법명과 신라인 김예신이다. 이들 중 김예신은 불교경전과 관련된 오음전문가로서, 명경 관련 음박사이면서 한음 전문가인 표신공[원진경]과 함께 일본에서 크게 활약한 것으로 보인다. 비록 현재까지 김예신의 행적에 관한 뚜렷한 기록을 찾아볼 수는 없으나, 그에 관한 사료 및 실담장 등 선행의 연구를 살펴보면, 일본 초기한자음의 오음이라고 하면 김예신, 일본 한자음의 한음이라고 하면 표신공이라는 고대일본 한자음의 대표적 인물로 인식되고 있는 것만큼은 사실이다. 일본의 실담학이 형성되기 이전 한 중 일 삼국의 관계성 안에서, 인도불전이 중국으로 전해지고 고대한국을 통하여 불교를 접한 일본은 그 불교적 한자음으로서 오음을 인식하였는데, 특히 일반 경구와는 달리 한자로 번역하지 않고 그 원형을 유지해야 하는 수많은 불교의 진언ㆍ다라니와 밀접한 관계를 가지는 한자음이 바로 오음이었다. 이는 진언밀교적 일본불교의 특성상 오음 위주의 진언 다라니 염송이 수행자에게는 그 어떤 수행의 요소보다도 중요한 기초였기 때문이다. 이에 본고에서는『일본삼대실록』, 『왜한삼재도회』 등을 비롯하여, 일본의 실담장, 그리고 일본학자들의 중국 한자음에 대한 여러 연구 가운데 오음과 관련된 김예신의 행적 및 그 선행의 연구 성과를 통하여, 그의 오음 일본전파에 관한 사실관계를 밝혀보려고 노력하였다. 본고를 계기로 신라김예신에 관한 긍정적이고 적극적인 논의를 기대해 본다. GO-On(吳音) and KANG-ON(漢音) in ancient Japan are the conceptual definition of Chinese sound in pronunciation aspects. It transmitted in ancient Japan through the ancient Korean people, which is appearing in Japanese history books and siddhavastu. There are two scholar, of the two men, the expert Silla Kim Ye-sin for GO-On associated with Buddhist scriptures seems to have the greater activity in conjunction with the expert of KANG-ON Biao Xin-gong[also called Yuan Jin-qing, he is a professor specializing in the reading of kanji in classic Confucianist texts] in ancient Japan. Even though, there is no distinct footprints of him, so we can’t determine about the relevant fact of GO-On, but there is a proof about Kim Ye-sin was involved in the branch of early Japan of GO-On in earlier Chinese sound and Biao Xin-gong was involved in another Japanese branch of pronunciation in Chinese characters, if we look at the preliminary study about Kim Ye-sin. So He had been mentioned as an exponent of the representative of Japan. Around at the study of Japan’s siddha., if we look at relationship among Korea, Japan and China, India carried Buddhist scriptures to China, and it was spreaded by China to ancient Korea and Japan, which Japan recognized the Buddhist GO-On that was all the Chinese sound, so after all, unlike the ordinary words of the scriptures, especially the Buddhist mantra and dharani is not translated into Chinese characters which we must maintain of its original form of Chinese sound that have a close relationship with GO-On, what we see in the character of Buddhism in Japan, it is more important than any other to a meditator when they chant sutra and mantra dharani to Buddha by GO-On in Japanese Buddhism. Therefore, in this paper, I can finally say that I checked out the truth of footsteps about Silla Kim Ye-sin through the various books, i.e. 『Nihon sandaizturoku』(日本三代實錄), 『Wakan sanzaizie』(倭漢三才圖會) written by Japanese people and through the studies of GO-On in Japan that performed by the several scholars. I look forward to using this research as instruments to be positive and active discussion about Silla Kim Ye-sin.

At the area of Yuhak, Cheonsaeng and Seongam mountains in Kyeongbuk, we studied the vegetation patterns with 75 plots on the base of Braun-Blanquet methods from March to October 2002. For the analysis of community patterns with 75 plots we used interspecies Affinity analysis method, DECORANA and TWINSPAN. The investigated area was divided into 17 communities with 177 species, and 20∼100% of treelayer, 10∼95% of shrublayer and 20∼100% of herblayer. By toe method of affinity analysis, it showed a big community with 86 species, but divided into 6 small groups by ordination and classification methods. Although it appeared as one group by the affinity test, the area divided into two groups by classification method at second level with eigenvalue of 0.320 and 0.430. It shows that the area of Yuhak, Cheonsaeng and Seongam mountains have own properties and in the process of succession.

노화가 인체 중간엽 줄기세포로부터 조골세포로의 증식 및 분화에 미치는 영향

백기현,태현정,오기원,이원영,조정기,권순용,강무일,차봉연,이광우,손호영,강성구,김춘추 대한내분비학회 2003 Endocrinology and metabolism Vol.18 No.3

연구배경: 일반적으로 골다공증과 연관된 위험인자로는 연령, 폐경, 약물, 불충분한 칼슘섭취, 만성질환 및 운동부족 등이 있는데, 특히 노화가 진행할수록 골밀도가 감소하는 것은 잘 알려져 있다. 노화와 관련하여 진행되는 골소실은 조골세포 및 전구조골세포의 기능적 결핍에 의한 골형성의 감소가 주요한 요인으로 여겨지고 있다. 그 동안 연령이 조골모 세포의 양과 조골모 세포로부터 성숙조골세포로의 분화 및 증식에 미치는 영향에 대한 일부 보고들이 있었으나 아직 일치된 견해는 없는 형편이다. 방법: 다양한 연령의 사람으로부터 골수를 채취, 중간엽 줄기세포가 포함된 단핵세포를 분리한 후 조골세포로 분화하기 좋은 조건하에서 배양하였다. 대상군은다시 젊은군과 노령군으로 구분하여 다양한 변수를 비교 분석하였다. 일차배양에서는 CFU-F를 계수하여 골수내 중간엽 줄기세포의 수를 추산하였고, 칼슘측정을 통하여 기질의 무기화 정도를 비교하였다. 계대배양후 이차배양에서는 시기별로 알카리성 포스파타제 활성도를 측정하고 오스테오칼신 mRNA의 발현을 관찰하여 젊은군과 노령군 사이의 증식능 차이를 비교하였다. 또한 이차배양 시기별로 MTT 측정을 하여 양군간에 증식능 차이가 있는지 알아보았다. 결과: 1. 일차배양 15일째에 평균 CFU-F의 수는 젊은군에서 유의하게 많았다(젊은군 148.3±28.9, 노령군 54.3±9.1, p=0.02). CFU-F의 평균면적은 젊은군에서 넓은 경향을 보였으나 통계적으로 유의하지는 않았다. 2. 일차배양 17일 경과 후 양군간에 기질 칼슘 침착정도는 유의한 차이를 보이지 않았다(젊은군 103.6±50.6, 노령군: 114.0±56.5, p=NS). 3. 이차배양 10일째에 젊은군에서 알카리성 포스파타제 활성도가 고령군에 비해 유의하게 높았다(젊은군: 935.5±115.0 U/mg, 노령군: 578.4±115.7U/mg,p.0.05). 고령군에서는 시간 경과에 따른 변화가 미약했으며 전반적으로 알카리성 포스파타제의 활성도가 젊은군에 비해 낮았다. 4. 이차배양도중 오스테오칼신 mRNA의 발현은 배양시기별로 젊은군에 비해 고령군에서 더 낮은 경향을 관찰할 수 있었다. 5. 이차배양 10일과 15일에 젊은군에서 노령군보다세포증식이 유의하게 증가된 양상을 보였다(10앓 젊은군 0.73±0.05, 노령군 0.58±0.04, p=0.05, 15일; 젊은군 0.80±0.05, 노령군 0.70±0.03, p=0.05).결론: 이상의 연구에서 저자들은 노령군에서 젊은군보다 골수 내 중간엽줄기세포의 수가 적고, 노령군에서 유래한 전구조골세포의 성숙조골세포로의 증식 및 분화가 젊은군 보다 감소해 있는 것을 관찰할 수 있었다. Background: Osteoblasts originate from osteoprogenitor cells in bone marrow stroma, termed mesenchymal stem cells (MSCs) or bone marrow stromal cells. Each MSC forms colonies (colony forming units-fibroblasts [CFL-Fs]) when cultured ex vivo. There are some reports about the age-related changes of the number and osteogenic potential of osteoprogenitor cells, but any relationship has not been clearly established in humans. In this study, we counted MSCs using CFU-Fs count and examined the proliferative capacity and differentiation potential of osteoprogenitor cells. Finally, we analyzed how these parameters varied with donor age. Methods: Bone marrow was obtained from the iliac crest of young (n=6, 27.2±8.6 years old) and old (n= 10, 57.4k6.7 years old) healthy donors. Mononuclear cells, including MSCs, were isolated and cultured in osteogenic medium. In primary culture, we compared the colony-forming efficiency of MSCs between the two groups and determined the matrix calcification. When primary culture showed near confluence, the cells were subcultured. Alkaline phosphatase activity, osteocalcin expression by RT-PCR and proliferative potential by MTT assay were examined by the time course of secondary culture. Results: At the 15th day of primary culture, the mean number of CFU-Fs was significantly higher in the younger donors (young: 148.3±28.9, old: 54.3±9.1, p=0.02) and the mean size of CFL-Fs was also larger in the younger donors than the older donors. However, matrix calcification was not different between the two groups (young: 103.6±50.6, old: 114.0±56.5, p=NS). In secondary culture, alkaline phosphatase activities were significantly lower in the older donors. The younger donors showed peak alkaline phosphatase activity at day 10, while the older donors didn't showed a remarkable peak (young: 935.5±115.OU/mg, old: 578.4±115.7U/mg, p<0.05). Total cell number as a proliferative index increased progressively during the secondary culture and a significantly greater cell number was noted in the younger donors. Osteocalcin expression was generally upregulated in the younger donors, but this was not statistically significant. Conclusion: Our study shows that the number of osteoprogenitor cells is decreased during aging and that the proliferative capacity and differentiation potential of osteoprogenitor cells seem to be reduced during aging (J Kor SOC Endocrinol 18:296-305, 2003).

한성준의 한국 전통춤 사장 : 승무를 중심으로

백현순;이예순;강미선;김현남;이현진 한국무용연구회 2007 한국무용연구 Vol.25 No.1

This paper aims to investigate the origin and movement of Buddhist dance, recognized as the most artistic one of Han sung Jun’s dances and from this draw the idea on Korean traditional dance. First, to summarize the idea on Buddhist dance, on the basis of his biography and historical background of his times, it is believed that the East would look upon the sky as the president of the universe and the origin of life as God; carry out the religious rituals as to natural phenomenon along with human beings. The spiritual thought during the ceremonies is certain to immanent in current Buddhist dance. Buddhist dance is also called “Bǔm-pae”, which means it has a close relationship with Buddhism. And his dance seems to be associated with Buddhism in a degree. The fact, however, that his dance ultimately has not any meaning in it, demonstrates Buddhist dance has the idea of emptiness, that is, “to stay at the quiet state without any mental affliction.” Second, the analysis of his dance shows that the principal motion of Buddhist dance is being represented as Pil-che, Hak-che and Goong-che. In other words, the stirring movement reveals that his dance certainly has a set pattern of points(Pil-che), lines(Hak-che) and circles(Goong-che); It is equivalent to the shape and spirit of the Endless(Mu-kǔk) and the Great Absolute(Tae-kǔk) in the eastern philosophy. Both of them are to result in ǔm-Yang and in this way, the idea of Takǔkǔmyang is obviously indwelling in Buddhist dance. 본 논문은 한국 전통춤의 맥을 이어 온 한성준의 승무를 대상으로 그 춤의 연원(淵源)과 춤사위의 구조(構造)룰 밝혀 춤의 실체인 한국 전통춤을 철학해 보고자 한 것으로 연구 결과는 다음과 같다. 첫째. 한성준 춤의 일대기를 바탕으로 그 시대적 배경에 따른 승우 춤 사상을 정리해 보면 동앙에서는 천(天)·신(神)에게 제사지내는 제천의식을 행해 왔는데 이때 행해지는 천신사상이 오늘날 승무 춤 속에 내재되어 있으며 또한 승무는 불교의식인 범패에서 기원 되어 성행된 것으로 볼 때 승무가 불교사상인 공사상(空思想) 깊은 연관이 있음을 알 수 있다. 둘째, 한성준 승무의 춤사위를 분석해 보면 승무 춤의 대표적인 춤사위가 필체(筆體), 학체(鶴體), 궁체(弓體)로 나타남을 알 수 있으며 이는 동양철학에 있어서 무극(無極)과 태극(太極)구조의 형상과 맥을 같이함을 알 수 있다. 무극과 태국은 곧 음양으로 귀결되며 따라서 승무 춤사위에는 태극음양사상(太極陰陽思想)이 내재되어 있음을 알 수 있다. 한국 전통춤은 익히 알다시피 악(惡), 가(歌), 무(舞)가 함께 어울려 시대의 흐름에 따라 한국인의 정서와 사고를 복합적으로 배태(胚胎)한 것이므로 한국 전통춤을 단순히 하나의 사상만으로 채울 수 없으므로 이상과 같은 결론은 한성준의 승무 춤에 내재되어 있는 한국춤 정신의 극히 일부분일 수 밖에 없다. 그럼에도 불구하고 승무 춤 속에 녹아있는 본질적 사상을 유추해 보고자 한 것은, 한국 전통춤의 대표적언 춤인 승무를 통해, 한국인의 정신인 춤 사상에 함축되어 있는 민족성을 도출해 낼 수 있는 바탕의 자료를 제시코자 한 것이다.
