Although having only become a unified nation in latter 19th century, Germany saw a movement centered on intellectuals to find culture via mental revolution after experiencing much confusion amidst rapid urbanization and materialism. Having expressed as they are such psychological states as anger, sorrow, repression, etc., which arise in reality, by remaining faithful to instinctive sensibility, the form naturally becomes distorted or exaggerated and continues on the tradition of romanticism of a powerful, dark, and introverted atmosphere. Having been discontinued after being branded as 'decadent art' by the Nazis of Fascism, expressionist art has returned in latter 20th century mainly centered on Germany, and this merits our attention. While neo expressionists actively use various objets and media, they metaphorically express hope about Germany's culture and society by again placing on the screen figures, myths, and symbols using rough brush touch, rich colors, etc., which past expressionists enjoyed using to represent the inner world of humans. As such, by examining expressionism, which can be seen as the origin of neo expressionism, we will discover the context in which these people conform to Germany's traditional romanticism and how they inherited and developed it.

To study stratigraphy of tidal basin deposits, related unconformity and source of late Holocene tidal sediments in Namyang Bay, west coast of Korea, total 8 vibracore sediments have been analyzed. The uppermost stratigraphic sequence of the late Holocene Namyang intertidal deposit overlies three different stratigraphic sequences (1) oxidized reddish brown muddy deposit (Yongduri Member), (2) oxidized yellow deposit (Kanweoldo Formation) and (3) the pre-Cambrian gneiss complex unconformably. Accordingly, three unconformities between those different sequences are recognized. The Namyang tidal deposits (late Holocene) with several meter thickness are mostly coarsening upward sequence suggesting transgressive phase during a continuous rise of sea level. The tidal deposit vibracored down to 4.5 m in depth contains clastic glauconite sands (2% in average) from 2.5 m to the vibracore bottom. These glauconite sands are considered to be transported to the site of Namyang Bay tidal sedimentation from offshore continental shelf of the Yellow Sea along the course of late Holocene sea-level rise.

대표적인 하천수질모형으로는 정상상태 모형인 QUAL2E와 비정상상태 모형인 CE-QUAL-RIV1이 있다. 정상 및 비정상상태 수질모형의 용도는 QUAL2E가 월별 및 순별 장기수질예측에 매우 활용도가 높다고 하면 CE-QUAL-RIV1는 갑작스런 수질사고와 같은 단기수질모의 즉, 댐방류 플러싱효과를 분석하는 효과에 매우 최적화된 모형이라 할 수 있다. 대부분의 하천 수질 예측모델이 비정상상태 흐름이 아닌 정상상태 흐름만을 고려하여 개발되었기 때문에 댐이나 수문에 의해 차단된 조절하천에서 부정류 흐름상태를 고려한 수질예측 모델이 필요하다. 본 연구의 대상 유역인 서낙동강은 상류에는 대저수문, 하류에는 녹산수문이 위치하고 있으며, 이와 같은 수문들에 의하여 하천의 유량이 조절되는 호소형 하천으로 자연적인 하천흐름이 원활하지 않은 정체수역이다. 따라서 장기간 오염물질이 퇴적되고 있으며, 이로 말미암아 수질오염이 매우 심한 곳이기도 하다. 서낙동강은 대저수문 유입량과 녹산수문 방류량에 따른 하천수질의 영향이 크며, 개발욕구가 강한 경상남도 김해시와 부산광역시 강서구가 위치한 수계로서 현재 발생부하량 뿐만 아니라 장래에 예상되는 발생부하량도 매우 큰 하천이다. 이와 같은 문제를 해결하기 위한 가장 근원적인 방안은 적절한 수문운영을 통하여 수역 내의 유속을 적절히 조절하고, 이를 통하여 수질개선 효과를 확보하는 것이다. 본 연구에서는 정체수역인 서낙동강의 대저수문 유입량과 녹산수문 방류량을 수문운영에 따라 하천유량을 통하여 실측하고, 이로 인한 수질 변화를 체계적으로 조사함으로써 다수의 수문운영 조건에 따른 비정상상태에서의 서낙동강 본류의 수질을 실측하여, 수질이 좋은 낙동강 본류 원수의 유입에 따른 수질개선 효과와 녹산수문 방류에 의한 플러싱 효과를 정량적으로 평가해보고자 하였다. 본 연구에서 실측된 수문 유입량 및 방류량 증가에 따른 하천수질변화 결과를 비정상 하천수질모형을 통해 검증하고, 이를 활용하여 서낙동강의 수질 개선을 위한 적절한 유량 및 운영방안을 구축할 수 있을 것으로 판단된다.

In the recycling procedure of the refrigerator, the fire frequently breaks out. In this study, to clarify the exact cause of the fire, the components and concentration of the materials produced in the process are analysed as well as the problems in the process system, and the protective measure to prevent the fire and the explosion fundamentally is proposed. In this procedure, the preventive measures of fire by removing the combustible materials such as polyurethane and inflammable gases, by removing the ignition sources and by reducing the oxygen concentration to the minimum are proposed along with the protective measures to reduce the damage in the fire. In the crushing procedure where the fire or explosion can break out in diverse ways, the forced ventilation or exhaust system applied to the small partial ventilation facility are installed to reduce the concentration of inflammable gas mixture to lower than the inflammable limit by injecting and exhausting the air forcibly.

In the previous paper (Choi et al., 1992), we found that a large but transient elevation in intracellular cGMP levels occur concomitant with the myoblast fusion. To establish the physiological significance of the elevation of cGMP levels, the change in guanylate cyclase activity dudng myoblast fusion and the correlation hetween various chemicals that may affect guanylate cyclase adivity and myoblast fusion were examined. Sodium nitroprusside, a nitric oxide-forming compound, induced a precocious fusion and increased guanylate cyclase activity compared to the control. Furthermore, L-NG-monomethyl arginine, specific inhibitor of L-arginine: nitric oxide synthase, inhibited the cell fusion in a dose-dependent manner, without affecting biochemical differentiation. On the basis of our present findings, we propose that the onset of myoblast fusion is somehow correlated with the rise in cellular cGMP levels that is regulated by the activation or inhibItIon of soluble guanylate cyclase, via as yet undefined mechanism but possibly through L-arginine: nitric oxide pathway.

Populus euramericana and Betula platyphylla var. japonica have been identified as possible species for use for phytoremediation of landfills. To identify the effects of waste leachate on growth and physiological characteristics in Populus euramericana and Betula platyphylla var. japonica, four different treatments were applied to seedlings for 3 months: leachate solution(100% leachate), 50% dilution(50% leachate: 50% water, v/v), 75% dilution(25% leachate: 75% water, v/v) and control(tab water) were applied to these two species. Treatment with waste leachate significantly stimulated both Populus euramericana and Betula platyphylla var. japonica height, diameter at root collar and biomass production relative to the water control. Chlorophyll contents, photosynthesis and transpiration of leachate irrigated-trees were significantly higher than those of water control. These results suggested that these two species could be suitable species for phytoremediation in landfills because these species showed good growth performance and were capable of taking up waste leachate.

This study was conducted to investigate effects of fertilization treatments (non-fertilizing, deep-fertilizing 20g, 50g, 100g, and surface-fertilizing 20g) on survival rate, growth performances, and seedling quality index (SQI) of container seedling and bare root seedling of Pinus densiflora in the field. There were no significantly differences in survival rate among fertilization treatments in the field. Besides, there was no toxic effect on seedling by over 100g fertilization in deep-fertilizing treatment. The root collar diameter and height of P. densiflora in both seedling types were the highest at 100g fertilization in deep-fertilizing treatments, and the biomass products and SQI were the same as above growth of root collar diameter and height. In most of the treatments, container seedlings showed better growth performances than bare root seedlings. In optimal fertilization, effect of fertilization was higher in container seedling than bare root seedling.

The most of groundwater with high U-concentration occur in the Jurassic granite of Gyeonggi massif and Ogcheon belt, and some of them occur in the Cretaceous granite of Ogcheon belt. On the contrary, they do not occur in the Jurassic granite of Yeongnam massif and the Cretaceou granite of Gyeongsang basin. The Jurassic and Cretacous granite, the host rock of high U-groundwater, were resulted from parental magma with high ratio of crustal material and highly differentiated product of fractional crystalization. These petrogenetic characteristics explain the geological evidence for preferential distribution of uraniferous groundwater in each host rock. It were reported recently that high U-content, low Th/U ratio and soluble mineral occurrence of uraninite in the two-mica granite of Daejeon area which have characteristics of S-type peraluminous and highly differntiated product. It is the mineralogical-geochemical evidences supporting the fact that the two-mica granite is the effective source of uranium in groundwater. The biotite granite and two-mica granite of Jurassic age were reported as biotite granite in many geological map even though two-mica granite occur locally. This fact suggest that the influence of two-mica granite can not be ignored in uraniferous groundwater hosted by biotite granite.

Purposes: This study is to examine the causes of limitations of modern western science and philosophy through Ayurvedic thought, and to seek the path of holism for the development of national healing projects. Methods: Therefore, it was inferred that the background of modern Western civilization and the reality of the national healing project would share the flow. In order to examine this, the difference between the East and West's 'recognition of the body and the mind' and the 'perspective on the origin of existence' was examined, and the characteristics of the Ayurvedic five-element novel were examined. Results: Through that process, the "mind and body dualism" in the West and the absence of the "empty element( 空 Śunya)" in Western four-element novels were pointed out as the cause of the limitations. In the sense that the 'empty element' is an invisible world and an immaterial world, it was concluded that the absence of justice was a limitation of Western civilization and a problem of the reality of the national healing project. Conclusions: I hope that this study will lead to continuous research on Ayurvedic ideology and research in the field of natural healing, thus contributing to the development of national healing projects and leading to health, well-being, and self-healing of the people.
