        Dylan Thomas 詩 硏究

        신현호 ( Hyun-ho¸ Shin ) 현대영미어문학회 1993 현대영미어문학 Vol.11 No.-

        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.

        Objective : The studies on liver effect in administration of western medicine have been well-established so far, but the studies on liver effect in administration or herbal medicine haven't been made. To make things worse, people who have liver disease generally believe that taking a herbal medicine is not useful to take care or their disease and even think it can cause liver disease. But this belief is not verified at all. So we feel the need to study about how taking herbal medicine affect to liver injury patient. Methods : We chose the 4 patient who seems to have the liver injury on the index of liver function test and we administrate the herbal medicine and after several day or weeks we recheck the liver function test. Results : Through the this method, we find the positive effect of taking herbal medicine on the patients who have the liver disease. Conclusions : Our results give no evidence that herbal medicine is harmful for liver disease. We need to study more about this.

        온실 난방부하 산정방법의 검증 및 틈새환기와 지중전열의 영향 분석

        신현호(Hyun-Ho Shin),남상운(Sang-Woon Nam) 한국원예학회 2015 원예과학기술지 Vol.33 No.5

        원예시설의 환경설계 중 난방부하 산정방법에 대한 검증을 위하여, 대규모 플라스틱 온실에서 총난방부하와 틈새환기율, 지중전열량을 계측하여 계산결과와 비교 분석하였고, 지중전열 및 틈새환기가 온실의 난방부하에 미치는 영향을 검토하였다. 실험기간 동안 실내기온은 13.3 ± 1.2℃, 실외기온은 -9.4~+7.2℃의 범위를 보였으며, 우리나라의 난방설계 외기온 범위에서 유효한 것으로 확인하였다. 가스트레이서법으로 측정한 틈새환기율은 평균 0.245h<SUP>-1</SUP>로 나타났다. 온실의 피복면적에 일정한 환기전열계수값을 사용하는 방법은 온실의 규모에 따라서 문제가 있는 것으로 분석되었다. 따라서 환기전열부하는 온실의 체적과 틈새환기율을 이용하는 방법이 합리적인 것으로 판단된다. 온실 중앙에서 측정한 지중열류는 실내외 기온차에 따라 음으로 약간 증가하는 경향을 보이고, 온실 측면에서 측정한 지중열류는 실내외 기온차에 따라 양으로 크게 증가하는 경향을 보였다. 계측 결과를 바탕으로 온실의 외주부를 통한 열손실 개념을 도입한 새로운 지중전열부하 산정 방법을 개발하였으며, 검증결과 잘 일치하는 것으로 나타났다. 관류열부하는 대체로 실내외 기온차에 비례하는 것으로 나타났으나, 열관류율은 작아지는 경향을 보였다. 따라서 관류열부하 산정시 설계조건에 따라 열관류율의 선택에 주의를 기울여야 할 것으로 판단된다. 실험온실의 열관류율은 평균 2.73W·m<SUP>-2</SUP>·℃<SUP>-1</SUP>로 단일피복의 플라스틱 온실 대비 60%의 열절감율을 보이는 것으로 나타났다. 전체 난방부하 중에서 관류열부하가 84.7~95.4%, 환기전열부하가 4.4~9.5%, 지중전열부하가 -0.2~+6.3%를 차지하는 것으로 나타났다. 관류열부하는 실내외 기온차가 낮은 그룹에서 더 큰 비율을 차지하고, 환기전열부하는 실내외 기온차가 높은 그룹에서 더 큰 비율을 차지하는 것으로 나타났다. 지중전열부하의 경우 실내외 기온차가 낮은 그룹에서는 부하를 경감시키는 방향으로 작용하고, 실내외 기온차에 따라 부하를 증가시키거나 경감시키는 방향으로 작용하는 것으로 나타났으므로 이 기준 온도차의 선택이 중요한 것으로 판단된다. 지중전열부하에 비하여는 환기전열부하가 더 큰 비중을 차지하므로 에너지 절감을 위해서는 틈새환기율을 줄일 수 있는 대책이 필요한 것으로 판단된다. To investigate a method for calculation of the heating load for environmental designs of horticultural facilities, measurements of total heating load, infiltration rate, and floor heat flux in a large-scale plastic greenhouse were analyzed comparatively with the calculation results. Effects of ground heat exchange and infiltration loss on the greenhouse heating load were examined. The ranges of the indoor and outdoor temperatures were 13.3 ± 1.2℃ and -9.4~+7.2℃ respectively during the experimental period. It was confirmed that the outdoor temperatures were valid in the range of the design temperatures for the greenhouse heating design in Korea. Average infiltration rate of the experimental greenhouse measured by a gas tracer method was 0.245 h<SUP>-1</SUP>. Applying a constant ventilation heat transfer coefficient to the covering area of the greenhouse was found to have a methodological problem in the case of various sizes of greenhouses. Thus, it was considered that the method of using the volume and the infiltration rate of greenhouses was reasonable for the infiltration loss. Floor heat flux measured in the center of the greenhouse tended to increase toward negative slightly according to the differences between indoor and outdoor temperature. By contrast, floor heat flux measured at the side of the greenhouse tended to increase greatly into plus according to the temperature differences. Based on the measured results, a new calculation method for ground heat exchange was developed by adopting the concept of heat loss through the perimeter of greenhouses. The developed method coincided closely with the experimental result. Average transmission heat loss was shown to be directly proportional to the differences between indoor and outdoor temperature, but the average overall heat transfer coefficient tended to decrease. Thus, in calculating the transmission heat loss, the overall heat transfer coefficient must be selected based on design conditions. The overall heat transfer coefficient of the experimental greenhouse averaged 2.73 W·m<SUP>-2</SUP>·C<SUP>-1</SUP>, which represents a 60% heat savings rate compared with plastic greenhouses with a single covering. The total heating load included, transmission heat loss of 84.7~95.4%, infiltration loss of 4.4~9.5%, and ground heat exchange of -0.2~+6.3%. The transmission heat loss accounted for larger proportions in groups with low differences between indoor and outdoor temperature, whereas infiltration heat loss played the larger role in groups with high temperature differences. Ground heat exchange could either heighten or lessen the heating load, depending on the difference between indoor and outdoor temperature. Therefore, the selection of a reference temperature difference is important. Since infiltration loss takes on greater importance than ground heat exchange, measures for lessening the infiltration loss are required to conserve energy.
