강남의 집값이 뜀박질하자 강북을 개발해 강남 수요를 이전시키겠다는 서울시의 야심찬 계획안이 올 2월 발표된 '강북 U턴 프로젝트'다. 이 프로젝트는 서울시에서 청사진만 내놓은 수준에 그쳐 있지만 시장 수요자들은 이러한 호재를 가만히 둘 리 없다. 이미 올 상반기 동안 용산, 뚝섬 주변의 아파트 값이 뜀박질을 했고 재개발 지역도 거래가 없는 상황에서 호가가 꾸준히 오르고 있다. 오는 7월 도시재정비촉진특별법 실행을 앞두고 '강북 U턴 프로젝트' 수혜지로 꼽힌 용산, 뚝섬, 은평 일대 부동산 시장을 돌아보았다.

This study analyzed the specific items and contents of district unit plan for responding to commercial gentrification on the west side of Gyeongbokgung Palace, Ikseon and Ttukseom surrounding area. By analyzing the major regulatory items and ranges currently used in the 'district unit plan' for responding to gentrification, it was intended to draw up the limitations of the district unit plan of the study target and the significant issues to be considered when establishing a district unit plan for future respond to gentrification. In the district unit plan around Seochon, Ikseon and Ttukseom surrounding area, location restrictions are imposed on franchises for responding to gentrification in common, and in the case of Ikseon and Ttukseom surrounding area, the maximum development scale is especially smaller than that of the surrounding areas. Also, in the Ttukseom surrounding area, incentives are given to the use of certain exterior materials to preserve regional characteristics.

We analyzed the meteorological and radiation characteristics of Seoul metropolitan area using data from energy flux towers that were installed and operated by the Weather Information Service Engine (WISE). The meteorological and radiation variables included temperature, pressure, wind speed, wind direction, relative humidity, surface temperature, rainfall amount, upward and downward solar radiation, upward and downward longwave radiation, albedo and emissivity from 14 energy flux stations located in the Seoul metropolitan area from July 2016 to July 2017. According to the monthly data during the period, the albedo is low and emissivity is high at the Jungnang station in the urban and opposite at Bucheon station in the suburban area. For a station in natural state, the albedo was higher than urban stations because solar radiation reflects effectively. Relatively high temperatures were shown at stations located in urban area with low albedo and high emissivity, in general. However, temperature was high at Gajwa and Ttukseom stations, the albedo was relatively high due to the station environment surrounded by glass wall buildings and the Han river. In the station located in suburban area, both emissivity and temperature were low. Among these stations, Bucheon station had the highest emissivity values because the surface temperature was relatively lower than that of the suburban area. As a result, the albedo decreased and the emissivity increased at stations in urban areas. Additionally, Seoul metropolitan area had less than $100Wm^{-2}$ of net radiation, which implied that radiation energy could be absorbed in the atmosphere.

Currently, melamine is being used variously in our lives such as resins, flame retardants, adhesive, laminate etc. And understandably sewer of stream of wastewater containing Melamine has also increased. GHS (Globally Harmonized System of Classification and Labelling of Chemicals) of EU safety guidelines says that it can cause cancer. Still, study on toxicity of Melamine is going on. In this research, melamine contamination level of the Han River and River Basin was analyzed by HPLC/UV. And the experiments of GAC adsorption were conducted and the model was studied. We collected the 3 same samples at the suburbs of Paldang Dam located in the relative upstream in Han River and Ttukseom amusement park, the downstream region and collected samples equally at the Hongreung stream, Wangsuk stream, Cheonggye stream among streams flowing into Han River and then measured Melamine concentration after purification. As a result, melamine was not detected at the suburbs of Paldang Dam and it was detected at Ttukseom amusement park, the downstream of it, in the concentration of $0.312{\mu}g/L$. The Wangsuk stream with $0.578{\mu}g/L$ highest Cheonggye stream and Hongreung stream was detected with each $0.197{\mu}g/L$ and $0.325{\mu}g/L$. Although the concentration was low in general, melamine detection could be checked at most point. In 1970, the world capacity of Melamine was estimated at 200,000 ton, with current production estimated to be 1,400,000 ton. Melamine of Han River and rivers flowing into Han River is present at low concentration but pollution will increase in the future due to increase of use. Depending on the size of activated carbon in the experiment were slightly different. But the breakthrough model is almost identical.
