Mountain streams, which are major components of an entire river network, play an important role as the source of water, sediment, coarse and fine organic matter, and nutrients for lowland rivers. Therefore, dynamics and downstream linkages of each compartment of the mountain stream can be essential for watershed management in catchment scale. The dynamics and downstream linkages are understood as a development of step-pool sequences along a river course. Recently, stream restoration after flooding event often employ the development of step-pool sequences in the world. In this paper, we 1) examined the geomorphic characteristics and the role of step-pool sequences in steep mountain streams by reviewing the results of past studies, and 2) introduced the case studies of stream restoration using step-pool sequences, and finally 3) addressed design methods considering geometry and stability of artificial step-pool sequences for stream restoration. Step-pool sequences play an important role not only as roughness with energy dissipation but also as heterogeneity of stream feature for aquatic habitat. Step-pool sequences, even if they are constructed artificially along a stream, may be effective for small stream restoration considering eco-friendly torrent controls. So far the artificial step-pool sequences were employed for mountainous streams, but those would be applied to urban stream.

This essay explores Congreve's last play The way of the World in terms of English new identity of the gentry represented by Mirabell in political, social and historical context of the Bloodless Revolution. Particularly, this essay focuses on behavioral differences between Mirabell and Fainall as characters who manage a certain type of acceptable Englishness through their heir. The acceptable Englishness separates what the differences are between two rakes from the outside of normative principle. The Way of the World reflects Lockean republican ideology in personal and familial relationships. Mirabell as a heroic rake represents new expectations for Englishmen who rejects absolute sovereign contrasted by Fainall's foreign tyrannical ways of domesticity. The Foreignness of Fainall's in the play is displaced by corollary change in the new model of English identity exemplified by Mirabell. Through the play, Congreve tends to satirize repressive morality of Hobbesian extremism and emphasizes the Revolution settlement based on consent sand trust instead. Mirabell's normative will harmonizes individual desire for happiness with social demand. In a sense Congreve's The Way of the World is a play reaching typical Restoration ending of intrigue and conspiracy through two rakes's interaction. Accordingly, this essay tries to show what separates the heroic rake from tyrannical libertine through their way of love, money, compromise and negotiation, which is their way of life.

This paper suggests to standardize railway accident restoration types as the standardized code and to develop standard operation procedures(SOP) for the efficient railway accident management and recovery system. First of all, occurred damage types as the existing railway accident types in both domestic and foreign cases have been carefully analyzed and then reclassified. Therefore, this study suggested the combination of 3 distinct code factors: restoration class, restoration object, and restoration location to standardize them. In addition, temporary restoration SOP will play a major role in the railway accident batabase management system and SOP for the damage limitation and the prevention of accident spread.

The wound healing process in fetus is quite different form that of adult. Regeneration plays an important role and scarless wound healing is possible in early gestational fetal period. Recently, the various effects of the hypoxia and reoxygenation in the wound healing process have been investigated by many researchers. The hypoxic state is known to alter protein synthesis and gene expression of TGF-${\beta}$, VEGF. The authors hypothesize there may be differences between fetal and adult fibroblast and this difference may play a possible role in the mechanism of scarless fetal wound healing. In this study, we investigated the growth of fibroblast, the amount of collagen deposition, the amount of protein synthesis and gene expression in TGF-${\beta}$(transforming growth factor-${\beta}$), VEGF(vascular endothelial growth factor) under the various hypoxic and reoxygenation conditions. Through these processes, we tried to determine the relationships between scarless fetal wound healing and hypoxic condition. In control group, fetal and adult fibroblasts were cultured under normoxic condition. The experimental groups were allocated into four different groups. The differences in TGF-beta, VEGF under 24, 48, 72 hours were statistically investigated. Compared to adult fibroblast group, there was a statistically significant increase (p<0.01) in the rates of protein synthesis in TGF-beta and VEGF of fetal fibroblast. In this study, these results may reflect the possibility that fetal fibroblast are more susceptible to change in oxygen and has a superior rate of angiogenesis through increased VEGF expression. The possible superiority of angiogenesis in fetal fibroblast may play an important role in scarless wound healing.

Most domestic small rivers and streams due to industrialization and urbanization have managed by concrete structures. The environmental functions of the river and stream are disappearing and urban streams play only the role of drainage systems. Also, the researches to restore natural streams are something yet to develop and not established the restoration for ecological functions of a small stream. Therefore the researches are required to develop ecological engineering system for watershed management system to handle various pollutants with restoration for ecological functions of a small stream. To develop this, the ecological engineering system for watershed management system could be developed with ecological conservation. In addition, ecological engineering system for watershed management system should be prior to conserve the habitat of biological resources and water conservation and applied to the original shape of streams. Also, it should be designed to restore the micro-topography of stream, the habitat of plant population in watershed. It is needed to develop the integrated researches to restore a small stream ecosystem.

드라마 연극이 희곡 텍스트를 무대 위에 재현하는데 관심을 두고 있다면, 포스트드라마 연극은 희곡 텍스트로부터 해방된 연극을 지향한다. 이 과정에서 드라마 연극이 만들어놓은 여러 경계들이 해체된다. 배우와 관객, 허구와 현실, 연극과 비연극, 작품과 사건, 언어와 비언어 등이 대표적인 경계의 이름이다. 이러한 경계의 해체는 드라마 연극에 의해서 잊혀졌던 고대 그리스 연극의 축제적 성격을 복원하는 계기가 된다. 이것은 아리스토텔레스 이래로 연극을 지배하였던 언어중심주의, 희곡중심주의를 해체하고 새로운 연극을 지향하게 한다. 언어중심주의, 희곡중심주의가 연극의 위기를 자초했다면, 포스트드라마 연극은 그것들을 해체함으로써 새로운 문화콘텐츠로서 관객과 소통하는 방법을 찾게 한다. 그 방법은 무엇보다 연극성의 회복에서 발견된다. 드라마 연극이 연극성보다 문학성에 종속된 것에 비해서 포스트드라마 연극은 문학성으로부터 해방된 연극성을 지향하고 있기 때문이다. 연극성이 강화된 포스트드라마 연극의 탈경계적 성격은 대중성 획득의 발판이 될 것이며, 이는 포스트드라마 연극의 문화콘텐츠로서의 가능성을 보여준다.
