Polypropylene (PP) was modified by grafting of maleic anhydride(MAH) and blending of ethylene-methacrylic acid (EMAA) copolymer in biphenyl solution at $170^{\circ}C$. The films were examined by $^{13}C$ NMR, FT-IR, contact angle measurement and adhesion test in various MAH and EMAA copolymer compositions. The transition temperatures of the films remained constant irrespectively of MAH and EMAA copolymer compositions. From NMR and FTIR spectra the grafting of MAH onto PP backbone was checked. With contact angle measurements, it could be confirmed that the grafting of MAH and adding of EMAA copolymer onto PP made its surface more polar. Through the adhesive force evaluations, the value of peeling strength gave the maximum at the 1wt% of MAH and 0.5 wt% of EMAA copolymer.

수압파쇄 기법은 암반 내에 파쇄를 수압을 이용하여 생성하거나 확장시키는 기술로서, 이렇게 생성된 파쇄대는 지반 안에서의 흐름의 통로 역할을 하며, 지하수가 자유롭게 흐르도록 한다. 본 연구에서는 최근에 수압파쇄 기법이 수행된 12개 관정 결과를 바탕으로 암종별 특성을 분명하게 파악하기 위하여 7개의 관정에서 추가로 수압파쇄를 실시하였다. 총 19개소에 대해 화성암(9개소), 변성암(4개소), 퇴적암(6개소)으로 대분하여 암종에 따른 수압파쇄의 가능성을 평가하였으며, 시험결과 화성암은 평균 $93.4\%$, 변성암은 평균 $103\%$, 퇴적암은 $42.2\%$의 산출량 증가를 보였다. 본 연구에서 수행된 수압파쇄의 적용은 암종별로 차이를 보이지만, 전반적으로 관정의 산출량을 증대시키는 효과적인 방법임을 확인하였다. Hydraulic fracturing is guaranteed to create or enlarge fracture, so the hydraulically created fracture acts as a conduit in the rock, allowing the groundwater to flow more freely through the fracture system. In a recent study, it showed that 12 wells where hydraulic fracturing was performed increased well production. However, it was estimated not to present representation by rock type due to not enough wells. Therefore, this study was performed to clarify the application of hydraulic fracturing at 19 water wells. Rocks were divided into igneous rocks (9 sites), metamorphic rocks (4 sites), and sedimentary rocks (6 sites) to evaluate representative features. As a result, the average of well yield increases $93.4\%$ in the igneous rocks, $103\%$ in the metamorphic rocks, and $42.2\%$ in the sedimentary rocks. Accordingly, hydraulic fracturing presented in this study provides an effective method for increasing well production

The construction of large scale harbor structures at Maengbang beach, which is located on the eastern coast of Korea, is of great concern because it may cause disastrous beach erosion in the vicinity. Therefore, a hydraulic model experiment was conducted to examine the morphological changes after such construction. The water depth was scaled using the method of Van Rijn (2010), which is a well-known scale law, but the results appeared to be overestimated. The present study developed a new scale law that applies an equilibrium beach profile formula to scale the model evolution to the prototype scale. When compared with survey data observed at Maengbang beach, the proposed method showed better agreement than the method of Van Rijn (2010).

본 연구에서는 한계유출량(threshold runoff), 특정 유역의 토양수분 상태 및 레이더 추정강우 등으로부터 한강유역의 돌발 홍수능(Flash Flood Guidance, FFG)-을 계산할 수 있는 한국형 돌발홍수 예경보시스템(KoFFG, Korea FFG)을 개발하기 위한 수문기상학적 이론적 배경을 제시하였다. 또한, FFG 산출물들을 보다 손쉽게 활용할 수 있도록 입력 데이터의 실시간 수집 및 자료 전처리 과정과 돌발홍수 예측결과를 표출할 수 있는 후처리 과정으로 구성된 실시간 KoFFG 시스템 설계방안을 제시하고, 레이더 및 RDAPS(Regional Data Assimilation and Prediction System) 강수자료를 활용한 돌발홍수 예경보 과정을 구축하였다. The objective of this study is to develop a Korea Flash Flood Guidance (KoFFG) system over the Han River basin. FFG is composed of threshold runoff computation and soil moisture accounting for hydrological component and radar rainfall estimates for meteorological component. In this paper, the background of hydrometeorological theory was described to construct FFG components. Each component is used to design the real-time flash flood guidance system composed of pre-processing for collecting various input data and post-processing for a dissemination and an easy use of the FFG products. Also, This system was constructed with the precipitation data of radar and RDAPS(Regional Data Assimilation and Prediction System) to forecast a flash flood warning and watching, respectively.
