鄕歌의 思想的 背景攷 : 彌勒思想을 中心으로 Stressing upon the Idea of Statue of Buddha

曺平煥 건국대학교 1990 論文集 Vol.30 No.1

The writer of this paper has looked first into the idea of Stone Statue of Buddha that is appeared in Buddhist Scripture, and also has examined how such were accepted in Silla Dynasty. Based on these, the writer has further studied about the works of Native Song, 'Hyang-ka' such as Dosol-ka(Written by Monk, Wolmyung-sa), MoJukjirang-ka(Written by Duko longing Hwarang "Jukji"), Anmin-ka(Written by Monk, Chungdam-sa) and Chankiparang-ka(Written to cherish the memory of the deceased Monk, Chungdam-sa).

To offer a reperence date for scientified vineyard management plan, I inuestigated yields according to increase in tree-age at seuera vineyard in young period. The results obtained were as follows: 1. Both varieties of campbell Early and Muscat Bailey A began to yield berries from the 2nd year after planting, but Delaware from the 3rd year. 2. The economic age of each variety was 3years after planting in both varieties of campbell Early and Muscat Bailey A, but 4 years in Delaware. 3. It was suggested that the fruiting period of each variety began from the 5~6 th year after plantning in Campbell Early, but from the 7th year in Delawara.

三國遺事 非鄕札表記詩歌 硏究

曺平煥 건국대학교 1982 論文集 Vol.14 No.1

The poems and songs, the subject of this study, are those odd works carried in Samkukyusa(삼국유사) excluding 14 pieces of Hyangka (향가, old Korean folk song) and Hyangchan(향찬). And a consideration had been given to the relation between the tales and the poems and songs prior to the study of those works. The sketch of the study is as follows: 1.We can see that the poems and songs and the tales, in the process of running parallel with each other for a long period of time, had developed into full bloom, one as legendary literature and the other as lyric literature, respectively. 2.The total number of works of our native poems and songs carried in Samkukyusa(삼국유사) is 19 pieces. Every one of these works sings about a phase or a problem of the then real life of our people, and therefore, the significance of the works can be said to have been so much grearter. 3.Eleven pieces of poems of Chinese language and three pieces of Kye(계) were also considered. Although these works were expressed in the form of Chinese poetry from the beginning, their sphere of works bear no resemblance to that of China, reflecting real life and singing the emotion of our people and, in consideration thereof, should be considered with great care. 4.Considering that tales, in which the real life of our people is reflected, forms the backbone of all the works from those native to our people to poems of Cinese language and Kye (계), it is hereby made clear that the study of tales should be done parallel with the study of poems and songs.

This paper presents the analysis of starting characteristics in wind power generating system. In this field, induction machine is mainly used as a generator. If it is applied at this field, there will be appeared the large inrush currents compared with rated current when starting. So this is a big problem for stability of power system and generating control system. According to control methods for starting, we can get different results. To analyze the proposed method, computer simulation using Psim are presented to support the discussion.

This writer had studied primarily on peculiar of the Buddhism during the Korea dynasty by this specific thesis and then conducted further its study for the matters of implicated between Buddhist thought and Sog-Yo(속요:popular song), Hyang-Ga(향가:native poem & song) and Ga-sa(가사:type of native poem & song) of which made and sang during the aforementioned period and consequently, the following conclusion has reached: Firstly, it was revealed that Seon-Jong(선종: one of Buddhism sect) kept definite standpoint rather than Gyo-Jong(교종: Buddhism sect) in relation to the Buddhism during the Korea dynasty. Secondly, Hwa-doo(화두) was utilized so often times as a means of an evangelization by Seon priests(선승) during the dynasty and Seon poem(선시) and Buddhistical Chinese poem(한시) were yielded by basis of large scale. Thirdly, although both Hyang-Ga and Ga-Sa are preserved their characteristics adequately, however, it was revealed that there were no available even single performance as recognizing pure Buddhist hymn among Sog-Yo(속요) Finally, concerning the study on Buddhist poem & song during the Korea dynasty, there enable to insist that Seon-Si(선시: Seon poem) and Buddhistical Han-Si(한시: Chinese poem) shall be emphasized than our current type of Han-Si

액체-고체 순환유동층에서 액상의 반경 방향 혼합 및 액체-고체 Chaotic 흐름 거동

직경이 0.102m이고 높이가 3.5m인 액체-고체 순환유동층의 상승관에서 압력요동 및 액체의 반경 방향 혼합 특성을 고찰하였다. 상승관에서 얻은 압력요동을 해석하기 위하여 chaos 이론을 도입하였다. 액체 유속, 유동입자의 크기 그리고 고체 유동입자의 순환속도가 연속액상의 반경방향 분산계수 및 압력요동의 위상공간투영과 상관차원에 미치는 영향을 결정하였다. 본 연구의 결과 액상의 반경방향 분산계수는 유동입자의 크기와 순환속도가 증가함에 따라 증가하였으며 액상의 유속이 증가함에 따라 감소하였다. 상승관에서 압력요동의 위상공간투영은 유동입자의 크기가 고체 유동입자의 순환속도가 증가함에 따라 점점 분산되고 복잡하게 되었으나, 액체유속이 증가함에 따라서는 위상공간에서 궤적의 분산이 다소 감소하는 경향을 나타내었다. 압력요동의 상관차원은 유동입자의 크기와 고체 순환속도가 증가함에 따라 증가하였으나, 액체의 유속이 증가함에 따라서는 큰 변화가 없었다. 본 연구의 결과는, 상승관에서 액상의 반경 방향 혼합 특성 압력요동 측정함으로써 실시간으로 예측하는 것을 가능하게 하여 실제공정에 응용함으로써 그 실용적 측면이 크다고 하겠다. Characteristics of pressure fluctuations and liquid dispersion in the radial direction were investigated in the riser of a liquid-solid circulating fluidized bed whose diameter was 0.102m and 3.5m in height. The concept of chaos theory was employed to analyze the pressure fluctuations obtained in the riser. Effects of liquid velocity, particle size, and solid circulation rate on the liquid radial dispersion coefficient and phase space portraits and correlation dimension of pressure fluctuations were determined. It was found that the radial dispersion coefficient of liquid phase increased with increasing particle size or solid circulation rate, but decreased with increasing liquid velocity. The attractor in the phase space portraits became more scattered and complicated with increasing particle size or solid circulation rate, but it became somewhat less scattered with increasing liquid velocity. The correlation dimension of pressure fluctuations increased with increasing particle size or solid circulation rate, but it did not change considerably with increasing liquid velocity. The results of this study enable us to predict the characteristics of liquid radial dispersion by means of the pressure fluctuations for the practical applications.

均如傳의 鄕歌硏究 : 形式을 中心으로

曺平煥 건국대학교 1984 論文集 Vol.18 No.1

As a result of through consideration both externally and substantially on the Hyang-Ka(鄕歌) transmitted in the Kyun-Yo Legend (均如傳), I have become to know that it is a "Yun-Hyang-Ka" (連鄕歌), which was written in the form of a continuation as wall as a 10-phrase style fort· form's sake. Therefore, this work of Songs and Poems can be said as the frrst long poem in the history of Korean Literature on Songs and Poem. Even if a little difficulty may exist in designating it as a long poem, it is considered unquestionable that it had arranged a key-point of a long poem for the future generations.

직경이 0.102 m이고 높이가 3.5 m인 액체-고체 순환유동층에서 액체의 점도가 고체입자의 체류량과 열전달계수에 미치는 영향을 검토하였다. 밀도가 2,500 kg/㎥인 유리구슬(d_(p)=1.0, 1.7, 2.1 또는 3.0 mm)과 CMC 용액(μ_(L)=0.96-38 mPas)을 각각 고체상과 액체상으로 사용하였다. 액체-고체 순환유동층에서 고체입자의 체류량은 액체의 유속이나 점도가 증가함에 따라 감소하였고 유동입자의 크기나 입자의 순환속도가 증가함에 따라 증가하였다. 액체-고체 순환유동층에서 열전달계수는 액체의 점도가 증가함에 따라 감소하였고 유동입자의 크기나 순환속도가 증가함에 따라 증가하였으나, 액체의 유속이 증가함에 따라서는 큰 변화가 없었다. 액체-고체 순환유동층에서 고체입자의 체류량과 열전달계수는 다음과 같이 실험변수와 무차원군에 의해 상관식으로 얻을 수 있었다.

Glass beads (d_(p)=1.0, 1.7, 2.1 or 3.0 ㎜) whose density is 2,500 ㎏/㎥ and aqueous solutions of carboxymethy cellulose (CMC)(μ_(L)=0.96-38 mPas) have been used as the solid and liquid phase, respectively. It has been found that the solid holdup decreases with increasing liquid velocity or viscosity, but it increases with increasing solid particle size or solid circulation rate. The heat transfer coefficient decreases with increasing liquid viscosity but it increases with increasing particle size or solid circulation rate, however, it does not change considerablely with increasing liquid velocity. The solid holdup and heat transfer coefficient have been well correlated in terms of operating variables or dimensionless groups as fellow: ◁수식원문참조▷
