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.

If a drama play is interested in recreating the play text on stage, the post-drama play aims at a drama that has been liberated from the play text. In this process, the boundaries created by drama theater are dismantled. Actors and audiences, fiction and reality, theater and non-theater, works and events, language and non-language are the names of typical boundaries. The demolition of these boundaries is an opportunity to restore the festival character of ancient Greek theater, which was forgotten by drama theater. This has led to the dismantling of language-centric and play-centricism, which has dominated the play since Aristotle, and has led to a new play. If language-centered, play-centricism has brought about the crisis of drama, the post-dramatic play dismisses them and finds ways to communicate with the audience as new cultural content. The method is found above all in the restoration of dramaturgy. This is because the post-drama plays are more dependent on theatricality than literature. The demilitarized nature of post-dramatic play with enhanced theatricality will be a stepping stone to popularization, and this shows the possibility of post-dramatic play as cultural contents.

The emergency restoration scenarios for efficient railway accident management and restoration were developed. The emergency restoration procedures defined by the worst case of emergency restoration and the important events was proposed based on questionnaires from specialists and the result of survey. Via these studies, the railway accident in the tunnel could be the worst case among all railway accident types. Therefore, educations for a restoration team in confined area condition should be planned and performed to recover the worst case accident. In order for the emergency restoration, when a railway accident is occurred, the restoration should be performed in orders of handing collapse of facilities, burying track, and derailment of vehicle in tunnel based on the statistical analysis. The result of priorities were established by the period of restoration. The standard operation system for efficient railway accident management was developed by synthesizing the worst case for rapid emergency restoration, and important events for the standard operation procedures according to each emergency restoration type. Through this study, the restoration operation system of railway accident are recommended. This paper suggests to develop emergency restoration scenarios for the efficient railway accident management and recovery system. The study results will contribute not only for insuring punctuality, but also for minimizing delays from accidents. Therefore, emergency restoration scenarios will play a major role in the SOP for the damage limitation and the prevention of accident spread.
