Dylan Thomas was in a rather peculiar position among the contemporary poets. Pound, Eliot, Yeats and Auden all represent an intellectualization of the poetic world or an implied view of poetry as social achievement. On the other hand, Thomas takes an attitude of antithetical movement such as William Blake. Thomas’ whole interest was in the self-exploration. He, casting light on the dark interior of the self, tried to discover himself. His poetry explores the subject of birth and death, creation and destruction in terms of primitivism, pantheism and finally love of man, accepting and celebrating the tragic human condition. In his early poetry based upon the “womb and tomb” motif, he attempted to overcome the fear of death by firmly believing the coexistence of birth and death. What Thomas found to symbolize this belief was the womb where birth and death seems to coexist. And he considered death as a part of nature’s process. His poetry of the middle period shows a greater involvement with others, as “A Refusal to Mourn the Death” and “After the funeral”, he does not deny the death of all things, including himself, but in anticipating this necessary destruction within poems and by participating in it, Thomas can overcome the fear of death. And the final period, characterized by longer, narrative poems like “Fern Hill” or “Poem in October” is one of acceptance of humanity and the tragic condition of man, or a movement toward affirmation and a conditional consent to the presence of death in life. Though Thomas dealt with the familiar theme to us, he dealt with it in a strange, surprising way. His originality and worthiness lies in the technique rather than themes. In talking of the change of technique, Thomas’s idiosyncratic language in his early poem is the reflection both of joy in playing with words and of a necessity to express the ineffable unity of the universe. While Thomas’ middle period shows a greater concern with the specifics of eternal reality displaced the primary vision, so that in the later poems ultimate realities are approached through nature and daily life instead of visionary imagery.

Mullitization in a multicomponent oxide system(alumina-kaolin-quartz-feldspar-talc) was studied as a function of sintering temperature from 1200 to 1500$^{\circ}C$ based upon a quantitative X-ray diffraction analysis. In the present study mullite grew as wiskers and its formation reaction showed characteristic there stages as follows In the first stage(1255-1295$^{\circ}C$) an appreciable mullitization(nucleation) occurred while corun-dum dissolution into glass (increasing glass content ) limited the rate of the reaction. At 1295-1335$^{\circ}C$ (second state) the reaction was significantly enhanced with a considerable glass consumption and with no appreciable change in corundum content. Finally (above 1335$^{\circ}C$) the reaction rate was attenuated re-markably with an apparent decrease in glass consumption rate. The impingement of mullite whiskers by oth-er whiskers and crystals was speculated to cause mullite growth in thickness direction with a slow growth rate resulting in the diminished reaction rate in the final stage.

This study was conducted in 8.2m wide single-span greenhouse to investigate the effect of presence or absence of rafter steel pipe joint and foundation conditions on greenhouse structural performance. Structural performance was evaluated by static loading test using the structural performance evaluation system for single-span greenhouse. The measured displacement was compared with the predicted result by numerical analysis. The displacement of each measurement location showed a significant difference regardless of the conditions of the foundation and presence or absence of rafter steel pipe joint. Compared to the hinge conditions, the difference in structural performance of the greenhouse in the fixed conditions was seen to be relatively large. The difference in structural performance according to presence or absence of rafter steel pipe joints, the lateral stiffness of the joint was 8.1% greater. 본 연구에서는 원예특작시설 내재해형 규격서에 등록되어 있는 폭이 넓은 단동온실(10-단동-5형)을 대상으로 기초의 경계조건과 서까래 강관의 이음 유무에 대해 실물 크기 실험을 실시하고 그 결과를 수치해석 결과와 비교하여 이음부가 있을 때 구조성능 차이에 대해 알아보았다. 각 측정 위치별 변위를 실험에서 측정한 값과 수치해석으로 예측한 값을 비교한 결과에서는 기초의 조건 및 서까래 강관 이음 유무에 상관없이 모두 상당한 차이를 보였고, 힌지 조건 보다 고정 조건이 상대적으로 차이가 컸다. 그리고 모든 절점을 강접합으로 가정하고 구조해석한 결과를 구조실험과 비교한 결과에서는 힌지조건이 고정조건 보다 잘 일치하였지만 해석값이 실험값 보다 크게 나타났다. 수치해석은 모든 절점을 강접합으로 가정했기 때문에 실제 성능과 달랐다. 따라서 현재 모든 절점을 강접합으로 가정하고 온실을 설계를 하면 과소설계될 우려가 있어 앞으로 신뢰성 높은 온실 설계를 위해서는 서까래와 도리가 교차하는 교차부 성능 특성을 고려한 구조해석 기술 개발이 이루어져야 할 것으로 판단된다.

본 논문에서는 Zhang & Huang 모델, AkasakaⅠ 모델, AkasakaⅡ 모델을 사용하여 충남 서산지역의 최근 10년간(2007~2016년)의 시각별 일사량을 예측한 후, 실측치와의 추정오차를 검토하였다. 검토 결과, MBE, RMSE 값이 AkasakaⅡ 모델에서 가장 작아 AkasakaⅡ 모델이 가장 우수한 것으로 확인되었다. 특히, AkaskaⅡ 모델의 경우, 국내 기상데이터를 통계 처리한 계수를 사용하여 추정오차를 추가적으로 낮춤으로써 건물 에너지 시뮬레이션 프로그램에 유용하게 활용할 수 있을 것으로 기대된다. In this paper, hourly solar radiations were predicted on Seosan area in Chungnam for late 10 years (2007-2016) by use of models of Zhang & Huang, Akasaka I, Akasaka II, and estimation errors were examined. As a result, the value of MBE and RMSE of Akasaka II model was the smallest, and it confirmed that Akasaka II model was the most excellent. Especially, it is expected that Akasaka II model will be able to use in building energy simulation, by reducing estimation errors by use of parameters processing domestic weather data statistically.

Recently, there has been a growing interest in mini-channels owing to their high heat transfer coefficients and compact sizes. To enhance the performance of mini-channels, different fin arrays have been studied widely. However, there have been a few studies comparing the performance of fin geometries. In this study, a comparative study of plate fins, pin fins, oblique fins is performed by using computational fluid dynamics. Mini-channels with pin fins shows the highest heat dissipation performances, and mini-channels with oblique fins shows the lowest pressure drop results.
