This paper asks what the Selection Attributes of urban open space are which carries out a role as an Urban Entertainment Destination. Case studies have chosen the Cheonggyecheon Waterfront, Seoul Forest Park, Seonyudo Park and Banpo Hangang Park as the representative open spaces in Seoul. The methods of study are observation investigation, a literature investigation and the survey to 233 visitors that conducted the ANOVA analysis and Regression analysis by SPSS 18.0. As a result, first, the urban open space in Seoul has had 8 elements of UED; Landscape, Multi anchoring, Contextual links, Programmability, Community, Branded identity, Security and Service. Second, they are being used not the neighborhood type but a wide area type. Third, Landscape, Security and Service are most important while Programmability and Community are less important than other factors in EUOS factors. Lastly, it was analysed that the influential factor of revisitation and satisfaction is Landscape, which is the common factor. Security in revisitation and Contextual links in satisfaction are especially additional factors. The landscape property is an important element to make an Entertainment Urban Open Space(EUOS). The virtue of landscape in the EUOS relates not only park facility or program that installed in the place but also the overall mood involving park user's activities in the place. To be a successful EUOS, a park facility, program and the overall mood involving user's activities need to be integrative approach to enhance the virtue of landscape.

Increasing discovery cases of underground storage facilities made of earth, wood, or stone are being reported from the recent excavation survey of the Baekje relics. Accordingly, the purpose of this study is to examine the structure and function of the underground storage facilities of Baekje following a classification made by the type and building method as follows: plask shape, wooden box shape, and stone box shape. The plask shape storage is the most representative underground storage of Baekje that has been found in numerous relics more than 600 sets around Hangang(Han River) and Geumgang(Geum River) from the Hansung period to Sabi period in Baekje Dynasty. It is a historical artefact as a part of the unique storage culture of Baekje around Hangang and Geumgang from the 3rd to 7th Century. Considering its structure and the example of Chinese one, it might had been used for a long-term storage of grains and various other items including earth wares. The storage facility in wooden box shape and stone box shape are found mostly in the relics Of Sabi period. Thus it might had taken some functions of the storage in traditional pouch shape which had decreased after the 6th Century. In particular, the wooden box shape and stone box shape storage required enormous labor force to build owing to their structure and building method. Thus, they were considered to had been used for official purposes in province fortress and citadel artefact. The wooden box shape storage facility is classified into flat rectangular type and square type based on the structure, and into Gagu type(架構式) and Juheol type(柱穴式) based on the building method. It might had been decided according to the geography and geological feature of the place where the storage was to be built. Considering the examples of Gwanbuk-ri relics and Weolpyong-dong relics, the wooden box shape storage facility might had been used for various items depending on the needs, including foods such as fruits and essential provisions at the military base. Considering the long-term food storage, the examples in Japan, and the functional characteristics of the underground storage facility, there is a possibility that the wooden and stone box shape storage facilities had been built so as to safely store important items in case of fire. This study is only a rudimentary examination for the storage facility in Baekje. Thus further studies are to be made specifically and comprehensively on the comparison with other regions, distribution pattern, discovered relics and artefacts, and functions.

The buffer is one of the major components of an engineered barrier system (EBS) for the disposal of high-level radioactive waste (HLW). As the buffer is located between a disposal canister and host rock, it is indispensable to assure the disposal safety of high-level radioactive waste. It can restrain the release of radionuclide and protect the canister from the inflow of groundwater. Since high quantity of heat from a disposal canister is released to the surrounding buffer, thermal properties of the buffer are very important parameters for the analysis of the entire disposal safety. Especially, temperature criteria of the compacted bentonite buffer can affect the design of HLW repository facility. Therefore, this paper investigated thermal properties for the Kyungju compacted bentonite buffer which is the only bentonite produced in South Korea. Hot wire method and dual probe method were used to measure thermal conductivity and specific heat capacity of the compacted bentonite buffer according to the temperature variation. Thermal conductivity and specific heat capacity were decreased dramatically when temperature variation was between $22^{\circ}C{\sim}110^{\circ}C$ as degree of saturation decreased according to the temperature variation. However, there was little variation under the high temperature condition at $110^{\circ}C{\sim}150^{\circ}C$.

SWAT모형은 장기간에 모의가 가능하며 다양한 토양이용과 토지특성을 고려할 수 있는 유역 단위 모형으로 많은 연구에서 이용된다. 이러한 유역단위 수문모형의 평가는 통계적 지수(NSE, R2)들로 모형의 적합성을 평가한다. NSE, R2는 상대적으로 큰 값에 대한 영향을 많이 받는다. 따라서 많은 강우량이 발생하는 시점에서의 유출량과 SS농도가 중요시되었다. 하지만 강우시에 하천으로 유입된 토양 중 일부는 하천에 퇴적물로 침전된다. 이 침전된 토양이 비강우시 바람 등과 같은 이유로 재부유되며 이로 인해 수중 DO를 고갈시켜 수생태계 악영향을 미친다. 이에 따라 비점오염저감시설 평가는 강우시 발생하는 SS농도도 중요하지만 비강우시 재부유되는 SS농도도 중요한 부분이다. SWAT모형에서는 하천 SS농도를 계산하는데 사용되는 매개변수가 강우시와 비강우시에 동일하게 적용되어 비강우시에 과대 산정되어 비강우시 SS농도가 증가되도록 sediment routing이 진행되고 있었다. 본 연구에서는 sediment routing을 수정하여 비강우시 SS농도를 실측 농도와 비슷하게 보정할 수 있도록 개선하였다. 비점오염관리지역 중 하나인 자운천 유역에 개선된 sediment routing을 적용하였다. 개선된 모형은 비강우시 농도가 잘 반영하는 것으로 확인되었다.

최근 기후변화로 인해 지역 및 시기별로 강수량이 편중되면서 가뭄(0.72회/년) 등 물 관련 재해가 빈번하게 발생하고 있으며, 가뭄의 강도 또한 심화되는 추세이다. 본 연구대상 지역인 태안군과 괴산군의 경우 기후변화 시나리오(RCP 4.5)를 적용, 미래(~2100년) 기상조건에 대하여 기존 농업용 저수지의 용수공급능력을 평가한 결과, 가뭄대응(내한) 능력이 감소하는 것으로 분석되었다. 한편, 농업가뭄의 경우 주로 영농기에 발생하여 장마가 시작되면서 해소되었으나, 최근 기후변화로 인해 지속기간이 점차 증가하여 가뭄피해가 매년 반복되고 있다. 그러나, 현재까지 추진된 가뭄대책의 경우 관정개발, 저수지 준설 등 단기·사후처방 중심의 대책이 마련되어 지속적인 재해관리와 예방에 많은 어려움을 겪고 있다. 이에 본 연구에서는 지역 맞춤형 가뭄대응 종합대책을 마련하여 기후 변화대비 안정적인 영농기반을 구축하고자 하였다. 기존시설 개선, 수요관리 등 최근 정부정책 방향과 재원조달 방안을 고려, 법적근거(농어촌정비법 등)에 의한 실현 가능한 사업계획을 수립하는 한편, 다목적 농촌용수 개발, 용수이용체계 재편 등 사업유형을 구분한 후 단계별(장·단기) 가뭄대책을 마련하였다. 가뭄대책 수립 시 한국농어촌공사에서 개발한 '수리수문 설계 시스템(K-HAS)'을 이용하여 용수 수요량을 산정하였고, 기존 수리시설물별 물 수지 분석을 통해 여유수량이 확보된 수원을 최대한 활용코자 하였다. 저수지 개발 등 신규 수자원 확보가 용이한 내륙·산간지역의 경우 중·대규모 저수지(유효저수량 1백만m³, 유역면적 200ha이상) 개발계획을 수립하는 한편 지역특성(형상, 표고차 등), 개발여건 및 경제성 등을 고려하여, 적정 개발범위(수혜면적 20ha이상)을 설정하였다. 한편, 신규 수자원개발이 어려운 도서·해안지역의 경우 용수 재이용(회귀수 활용) 및 담수호 내 염해방지시설을 도입하는 등 지역 맞춤형 가뭄대책을 수립하였다. 본 연구에서 제시한 단계별(장·단기) 가뭄대책이 차질없이 시행될 경우 기후변화 대비 안정적인 농업용수공급이 가능하고, 상습가뭄 발생(물 부족) 지역에 대하여 효율적이고 합리적인 물(수요·공급)관리가 가능할 것으로 기대된다.
