유역 물순환 개선 기술은 기후변화 및 토지이용변화가 진행 중에 있거나 예상되는 지역에 대하여 강우-유출수를 지연, 저류, 침투시켜 지속가능한 물순환체계를 유지?회복하도록 하는 기술이라 할 수 있다. 기후변화 및 토지이용변화에 따른 영향을 평가하고, 지속가능한 유역 물순환체계를 구축하여 적응 전략을 체계적으로 수립하기 위해서는 물순환 개선 기술의 정립 및 개발이 필수적이다. 그러나 현재 유역 물순환 개선기술은 일부 시가화 지역에 국한되어 있어 유역 규모의 개선 전략을 수립하는데 한계가 있다. 또한, 물순환계의 변화량을 평가하기 위한 모형화 기법 역시 해외에서 개발된 기술을 여과 없이 도입하여 국내의 환경을 충분히 반영하기는 어렵다. 개발된 유역 물순환 개선 및 평가시스템은 기존 국가연구개발사업을 통해 개발되고 사업화에 성공한 바 있는 유역 물순환 평가 모형인 CAT(Catchment hydrologic cycle Assessment Tool)을 수정 및 개선하여 기후변화에 따른 영향을 평가하고 적응 대책을 수립하기 위한 실무적인 소프트웨어이다. 침투트렌치, 식생침투트렌치, 습지, 저류지, 빗물탱크 등의 물순환개선시설에 대한 효과를 평가할 수 있도록 개별시설의 제원에 따른 물순환개선 효과를 정량적으로 평가하여 제시한다. 기후변화에 따른 장기간의 유역 물순환을 평가하기 위해서는 물리적 매개변수 기반의 수문해석 보다는 단순환된 개념적 매개변수 기반의 집중형 장기유출 해석이 필요할 수 있다. 따라서 국내외에서 많이 사용되고 있는 장기 일유출 모형(GR4J, GSM, HBV, SYMHYD, TANK, TPHM 등)을 유역 물순환 개선 평가 플랫폼에 탑재함으로써 소유역의 특성을 반영한 기후변화 적응 일유출 해석이 가능하도록 하였으며, 각 모형들의 매개변수는 수동보정 외에도 SCE-UA를 이용한 자동보정이 가능하도록 시스템으로 구축하였다. 개발된 유역물순환 개선 및 평가시스템은 실무적 차원에서 기후변화에 따른 유역 물순환 개선 기술을 적용하고 평가하는데 있어서 매개변수 입력자료 구축에 따른 자원 소요 시간 및 시스템 개발 비용을 획기적으로 단축시켰으며 국외 의존도가 높은 수문 해석모형을 국내 기술로 개발함으로써 기술자립도를 높이고 국내 및 해외의 유역의 성공적인 적용을 통하여 성능을 입증하였다. 기후변화에 따른 수자원의 재평가, 개선시설의 정량적 평가 및 하천유역의 수자원관리 실무에 적용성이 높을 것으로 기대된다.

Works recreated modernly succeeding classics often appear in novels, plays and movies. Observing 'modern succession and transfiguration of classics', 1 became curious about 'recreation of classics' in Sijo genre, and in that interest this thesis begins the argument. I identified that many Sijo are recreations of classics, and also classical literature are continually being transformed into modern Sijo. Especially Sijo of Lee Guang-Soo in 1920s and Sijo of Cho Un In 1940s are pioneering works. Thereafter modern Sijo have been continuously recreated from classics. This paper is about what are the meanings of modern Sijo in this category, and how should they advance. Also this argument will indicate how Sijo will be created in the future. Transforming classics into modern works is a valuable task, because it succeeds traditional culture and connects the classics' age to the modem age. For example, the Sijo of Lee Guang-Soo and Cho Un have significance in terms of literature history. The problem lies in modern Sijo that is creatively experimenting with classics succeeding those. Many modem Sijo are created attaching too much importance to the technique of contents, not comprehending the structural principles and formal aesthetics of Sijo. Thus, Sijo that adopt classics modernly reveals the limit of creation. Furthermore, recreating Sijo with the original contents untouched has no meaning at all. From this standpoint, modern Sijo recreated from classics can be reasonable only when they reflect the life, culture. and reality of present and comprehend the formal aesthetics of Sijo.

Daseuk Yeungmo Ryu, the author of the most Sijo poems in the history of Korean Literature, and his Sijo poems were once introduced by me. which is a small part of his world of Sijo, though. The goal of this study is, as its succeeding research, to reveal the features of Daseuk's Sijo poems and their significance in detail. There have been not a few poems which accepted religious contents in the history of Korean literature. Especially, Gesong In the Buddhist Zen is a typical example of the encounter between literature and religion. What is more. Buddhism was in alliance with Hyang-go in the Silla dynasty and with Gasa in the Chosun dynasty. Gasa was effectively used in accepting Buddhism as well as Taoism and Catholicism. Sijo has seemed to be farther from religion than Gasa has. However, Daseuk, a renowned religious thinker in the 21st century. expressed his religious ideas in Sijo, which has not been found in the history of Sijo before. Considering Hangeul as a special tool of expression, Daseuk delivered his condensed ideas in poetic dictions in a unique way. Each word in his Sijo poems implies his religious ideas, which are marked in a special transcription. It makes his Sijo difficult to understand. Yeungmo Ryu's Sijo poems should not be left unnoticed just because they are hard to understand but should have follow-up researches so that Daseuk's Sijo, which is the most in number and the most unique in its style, have to be embraced in Korean literature.

This paper is a study on the Jeonwonsasiga of Shin Gye Young. Jeonwonsasiga is as a out of Sasiga-Line(사시가계) Yeonsijo(연시조), the singing Spring. Summer. Autumn, Winter and Jesuk. The meanwhile, a study on the Jeonwonsasiga is in the relations with other literary works, or a history of Siga in 17th century. A out of specific character's of Jeonwonsasiga is the singing Spring, Summer, Autumn, Winter and Jesuk about order. Jesuk with a New year's Eve, is the stand for a watch night.'Chun Ha Chu Dong(Spring, Summer, Autumn, Winter, 춘하추동)' are included in the Sasi of One Year(일년 사시), And the Jesuk is included in the Sasi of one day(하루 사시). Buy the way, Jeonwonsasiga make an equal about all of two. And then, this paper is focused on the 'Jesuk'. The role of Jesuk is coexistence together with the Sasi of One Year and the Sasi of one day. That is to say, Jeonwonsasiga's singing from the 1st works to the 8st works are the Sasi of One Year in the surface. But, singing the Sasi of One Day of 'Dan Ju Mo Ya(단주모야)' in the inside story. And Jesuk is a finished role the mean's of literary works. And this provide an opportunity which can be speaker's recognition of Jeonwon (전원). The Jeonwonsasiga of ten works are have a value of Yeonsijo in continyal structure. And so. it is to be watched sense of proportion of Yeonsijo in the 17th century.

The genetic algorithm (GA) and branch and bound (B&B) methods are the useful methods of searching the optimal project combination (combinatorial optimization) to maximize the project effect considering the budget constraint and the balance of regional development with regard to the Urban Regeneration New Deal policy, the core real estate policy of the Moon Jae-in government. The Ministry of Land, Infrastructure, and Transport (MOLIT) will choose 13 central-city-area-type projects, 2 economic-base-type projects, and 10 public-company-proposal-type projects among the numerous projects from 16 local governments while each government can apply only 4 projects, respectively, for the 2017 Urban Regeneration New Deal project. If MOLIT selects only those projects with a project effect maximization purpose, there will be unselected regions, which will harm the balance of regional development. For this reason, an optimization model is proposed herein, and a combinatorial optimization method using the GA and B&B methods should be sought to satisfy the various constraints with the object function. Going forward, it is expected that both these methods will present rational decision-making criteria if the central government allocates a special-purpose-limited budget to many local governments.

Rimbaud's prose poem, Barbare in Illuminations, is known for its abstruseness with regard to forms, themes, metaphors. This paper first analyzes the poem's grammatical structure to make sense of such an inscrutable piece of work, then discusses its autotextuality in order to decipher its meaning by comparison with Rimbaud's other works. Autotextuality, a method of literary interpretation of Rimbaud's prose poem presented by Steve Murphy, refers to the intertextuality between the author's works. Despite some previous researches focusing on the intertextuality of Barbare, previous authors have failed not only to find its meaning but also to determine its significance. The abstruseness of Rimbaud's Barbare is sometimes considered an example of the meaningless of Rimbaud's work. However, examining the textual structure and the autotextuality builds meaning, rather than rendering the work meaningless. Barbare which consists entirely of noun phrases and metaphors means destruction, fusion and the pure power of regeneration in the original context of Rimbaud's work. This poem is Rimbaud's answer to Baudelaire's poetic question, Any of where out of World, and presents a strange scenery that uses 'the eternal female voice' to reach the Vulcan in the North Pole. Interpretation of Barbare could provide a methodology for reading the difficult Illuminations. The kind of analyses used are, for example, analysis of the text, analysis of verbal indicators, autotextuality, and an understanding of the joy and the solitude in the silence of the poem. Understanding Barbare may provide a method of interpreting the abstruseness of Illuminations. Through this approach, we can connect and combine every fragment of the Illuminations, so that we can reconstruct the story and the adventure contained therein.

Despite the rapid expansion of satellite images supply, the application of imagery is often restricted due to unautomated image processing. This paper presents the automated process for the selection of training areas which are essential to conducting supervised image classification. The training areas were selected based on the prior and cover information. After the selection, the training data were used to classify land cover in an urban area with the latest image and the classification accuracy was valuated. The automatic selection of training area was processed with following steps, 1) to redraw inner areas of prior land cover polygon with negative buffer (-15m) 2) to select the polygons with proper size of area ($2,000{\sim}200,000m^2$) 3) to calculate the mean and standard deviation of reflectance and NDVI of the polygons 4) to select the polygons having characteristic mean value of each land cover type with minimum standard deviation. The supervised image classification was conducted using the automatically selected training data with Sentinel-2 images in 2017. The accuracy of land cover classification was 86.9% ($\hat{K}=0.81$). The result shows that the process of automatic selection is effective in image processing and able to contribute to solving the bottleneck in the application of imagery.

The purpose of this study is to analyze how Corporate Real Estate Ratio affects Firm's Value for KOSPI Companies and KOSDAQ Companies. The period of analysis is the period of the Financial Crisis (2007-2008), the period immediately after the Financial Crisis (2009-2011), and the period following the introduction of IFRS (2012-2016). The samples of 2761 KOSPI Companies years and 3719 KOSDAQ Companies years are used in this study. The result of Regression Analysis shows that the higher Corporate Real Estate Ratio is, the more negative Firm's Value is. In the comparison of markets, both KOSPI Companies and KOSDAQ Companies had no statistically significant effects during the Financial Crisis. Although KOSDAQ Companies had a greater negative effect on the Firm's Value than KOSPI Companies right after the Financial Crisis, KOSPI Companies have had a greater negative influence on the Firm's Value than KOSDAQ Companies since the introduction of IFRS. Therefore, each corporation should pay more attention to identifying the appropriate amount of their Corporate Real Estate Ratio and should continue to analyze and make decisions on the most efficient use of real estate which is owned by each company. This study shows speciality in dividing into three period, such as the period of the Financial Crisis, the period immediately after the Financial Crisis, and the period following the introduction of IFRS and comparing the degree of influence on the KOSPI Companies and KOSDAQ Companies for the each period. I hope to study the factors that affect the company's real estate policy.

Drought is a longer lasting and more extensive disaster than other natural disasters, resulting in significant socioeconomic damage. Even though drought events have same severity, their damage vary from region to region because of spatial, technical, economic, and social circumstances. In this study, drought vulnerability was assessed considering socioeconomic factors. Preliminary factors were identified from the case study for Chungcheong province, and evaluative factors were selected by applying the principal component analysis. The entropy method was applied to determine the weights of evaluative factors. As a result, in Chungcheong province, farm population, number of recipient of basic living, water fare gap indicator, area of industrial complex, amount of underground water usage, amount of water available per capita, water supply ratio, financial soundness for water resources, amount of domestic water usage, amount of agricultural water usage and agricultural land area were chosen as the evaluative factors. Among them, the factors associated with agriculture had larger weights. The overall assessment of vulnerability indicated that Cheongju, Dangjin and Seosan were the most vulnerable to drought.
