This essay is about the considering the mutual relevance of animation and literary work in a case. The television animation Heidi, Girl of the Alps made in Japan is the most famous media version of the original novel. The novel Heidi by the Switzerland writer Johanna Spyri has been translated in a lot of countries, and the original Heidi has been adapted for mass media - literary(translation), movie, play, animation, cartoon, picture book. Here, with the relation between animation Heidi, Girl of the Alps and Spyri's Heidi and the present condition of the change in Japan and Korea, the relevance of animation and literature was reconsidered. First, Heidi, Girl of the Alps and Heidi have the different characteristic as media, and the content has some different set-up. On the other hand, original soul is inherited in the animation. Second, the animation has affected Heidi related visual image and the original media diffusion. The above consideration from a viewpoint of the mutual relevance between media shows the importance to return aiming at mutual understanding of animation and literature and mutual value between the diversified media. Moreover, it suggests a possibility of leading to creation of the energy which results in transformation also to action.

In this study, threshold runoff which is a hydrologic component of flash flood guidance(FFG) is estimated by using Manning's bankfull flow and Geomorphoclimatic Instantaneous Unit Hydrograph(GcIUH) methods on Han River watershed. Geographic Information System(GIS) and 3' Digital Elevation Model database have been used to prepare the basin parameters of a very fine drainage area($1.02\~56.41km^2$), stream length and stream slope for threshold runoff computation. Also, cross-sectional data of basin and stream channel are collected for a statistical analysis of regional regression relationships and then those are used to estimate the stream parameters. The estimated threshold runoff values are ranged from 2 mm/h to 14 mm/6hr on Han River headwater basin with the 1-hour duration values are$97\%$ up to 8mm and the 6-hour values are $98\%$ up to 14mm. The sensitivity analysis shows that threshold runoff is more variative to the stream channel cross-sectional factors such as a stream slope, top width and friction slope than the drainage area. In comparisons between the computed threshold runoffs on this study area and the three other regions in the United States, the computed results on Han River watershed are reasonable.

As the Fundamentals of Construction Business Act was revised in December 2004 and its implementing ordinances and enforcement regulations were adjusted in June 2005, the screening system of low price subcontracting has been an obligation to the public owners, having brought about arguments for and against since it enacted in 1983. The statutes for low price subcontracting have been reinforced from this year; for example, it underlines to submit to a project and builds an information network of subcontracting works. The system's original intention was that prevents shoddy and fraudulent constructions caused by low price subcontracting and precludes disturbances of fair trade by screening that whether it satisfies the conditions or not in advance. But, the criterion for the existing low price subcontracting has several issues having held up a true mirror to the real situation. It is arguable to discharge an important task with the primary purpose. This dissertation have researched the problem with a deposit of subcontract and the low price subcontracting basic rate are being used by the criteria for deciding whether it is a low price subcontracting or not, so showing the plan of reformation based on the findings, it wishes to contribute toward making the most of the system's essential intent.

This paper is about Zhuzi(朱子) writings entitled Yixueqimeng("易學啓蒙"). There are only four research articles on Yixueqimeng("易學啓蒙"), although it had taken important role in the process of formation of Zhuzi(朱子) study of changes, comparing with 30 different kinds of research on his works after this Yixueqimeng("易學啓蒙"). In line with this, the author intends to make this paper as a full-scale research article on Zhuzi(朱子) work - Yixueqimeng("易學啓蒙"). Zhuzi(朱子) exposes the meaning of the Xiangshuyixue(象數易學), to wit, the emblem and numerology of Emblem and Numerology in interpreting Zhouyi("周易") again by accepting Hetu("河圖") and Luoshu("洛書"). When discussing the Zhouyi("周易"), Yiliyixue(義理易學) had drawn supports from Wangbi(王弼) Deyiwangxianglun(得意忘象論). Likewise, Zhuzi(朱子) tried to ruminate upon the meaning of the Hetu("河圖") and Luoshu("洛書") through the Yixueqimeng("易學啓蒙"). As he interprets all things through Hetu("河圖") and Luoshu("洛書"), these two systems of emblem have become essential. Even in Shifa(筮法), he elicited Dayanzhishu(大衍之數) from Hetu("河圖") and Luoshu("洛書") so that he related the divination rule to Hetu("河圖") and Luoshu("洛書"). By doing so, Zhuzi(朱子) concatenates Dayanzhishu(大衍之數) to Hetu("河圖") and Luoshu("洛書") too. Furthermore, by interpreting Yongjiu(用九) and Yongliu(用六), which belong to Qiangua(乾卦) and Kungua(坤卦) as prognostication that will be referred to when all six-line symbols are changed, he had made a great contribution to the history of Zhouyi("周易") study. Zhuzi(朱子) is responsible for a sizable part of the history of Zhouyi("周易") study as much as Wangbi(王弼) and Chengyi(程?). Of course, there are some parts where efforts were made in vain, however, the method to interpret the Zhouyi("周易") have developed day by day owing to the efforts of Zhuzi(朱子).

In this study, a comparative review was conducted on how to use RGB images to obtain river topographic information, which is one of the most essential data for eco-friendly river management and flood level analysis. In terms of the topographic information of river zone, to obtain the topographic information of flow section is one of the difficult topic, therefore, this study focused on estimating the river topographic information of flow section through RGB images. For this study, the river topography surveying was directly conducted using ADCP and RTK-GPS, and at the same time, and orthomosiac image were created using high-resolution images obtained by drone photography. And then, the existing developed regression equations were applied to the result of channel topography surveying by ADCP and the band values of the RGB images, and the channel bathymetry in the study area was estimated using the regression equation that showed the best predictability. In addition, CCHE2D flow modeling was simulated to perform comparative verification of the topographical informations. The modeling result with the image-based topographical information provided better water depth and current velocity simulation results, when it compared to the directly measured topographical information for which measurement of the sub-section was not performed. It is concluded that river topographic information could be obtained from RGB images, and if additional research was conducted, it could be used as a method of obtaining efficient river topographic information for river management.

하도에서의 홍수추적시 유역내의 지류 혹은 지표 및 지하수등은 추적대상이 되는 하도구간내에서 측방유입량의 되어 유출수문곡선의 첨두유량, 첨두시간, 수문곡선의 형태등에 영향을 주므로 정확한 산정이 필요하며, 직접유출수문곡선에서 측방유입량은 지표유출에 의해 발생하므로 강우발생시 유역에서 하도까지 걸리는 도달시간의 산정이나 측방유입속도의 결정이 필요하다. 기존의 강우-유출 수문모형은 지표수흐름의 복잡한 메카니즘 및 수리특성을 규명하는데 어려움이 있다. 본 연구에서는 관측유입수문곡선 및 유출수문곡선을 이용하여 측방유입량을 산정하고, 하도구간으로 유입되는 기지의 측방유입량으로부터 수리학적 홍수추적을 위한 지배방정식인 Saint-Venant방정식의 수치해법중 하나인 양해법에 diffusing scheme을 적용하였다. 또한 하도 전구간에 동일한 측방유입속도로 유입될 경우와 하도중심을 기점으로 상류부와 하류부로 구분하여 두 구간의 측방유입속도가 다른 두가지 경우에 대해 측방유입속도를 역추정하였으며, 계산 유출 수문곡선과 관측 유출수문곡선을 비교$\cdot$분석함으로써 구성한 홍수추적모형에 대한 정확성과 타당성, 적용 가능성등을 검증하고자 하였다.

하천수를 취수원으로 하는 우리나라의 많은 취수장의 경우, 유사유입 및 유로 변경에 따른 취수장애를 겪고 있으나 유로의 변화특성을 분석하고 취수장 위치선정에 활용한 수 있는 실무적 기법에 대한 연구는 거의 없는 실정이다. 따라서 본 연구에서는 유로가 좌${\cdot}$우안으로 수시로 바뀌어 갈수기는 물론 평수기에도 취수장애를 겪고 있어 대책 강구가 요구되는 국내 취수장을 선정하고 취수지점의 계속적인 하상 및 유로변동 현상을 규명하여 안정적인 취수를 가능케 하는 근본적인 대책을 수립하기 위한 유로변화 특성 분석기법을 제시하였다. 연구내용으로는 과거 30여년에 걸친 하도의 평면학적 변화양상을 인공위성영상자료, 지형도자료 및 하도단면 실측자료를 활용하여 각 지점별 유로변화에 대한 동계분석을 실시하였다. 또한 하도의 전단응력, 마찰 속도 등을 산정하여 하상형태를 분석하여 대상구간의 흐름특성을 분석하였다. 분석결과 하도의 사행은 지속적으로 진행되고 있음을 알 수 있으며 특히 취수장부터 상류 수km구간 하도에서는 밤섬이 지속적으로 생긴다 사라지는 현상이 반복되고 있음을 확인할 수 있었다. 취수장 주변에서는 유로의 변동이 하폭의 $70\%$에 달하는 심한 유로변화 특성을 나타내고 있어 취수지점으로 적당치 못함을 알수 있었으며 주변 상하류 십수 km구간 중에는 유로의 변화가 거의 없는 구간도 존재함을 알 수 있이 본 연구의 유로변화 분석기법이 향후 유로변화 분석 및 취수장 건설 위치 선정에 효과적인 분석기법으로 활용 가능함을 입증하였다.
