Structure of Wind and Turbulence below and above a building canopy during the BBMEX–Wind Campaign period in Seoul Open
A building-block urban meteorological observation experiment – wind (BBMEX-Wind) campaign was carried out to observe vertical profile of 3-dimensional wind speed below and above the building canopy of a street canyon at Gangnam district in…
Converting a high-level air temperature and wind speed to a reference level ones: Application to the Ieodo Ocean Research Station Open
Air temperature and wind speed observed at reference levels (the former 2 m and the latter 10 m) are essential for validating a performance of meteorological models as well as for parameterizing a boundary-layer processes such as air-sea m…
Development of a Pedestrian-Feeling Temperature Prediction (PeFT) Model during the Heatwave using Artificial Intelligence Open
The urban heat island is intensified due to the continuous temperature increase caused by climate change, leading to consistent property and casualty damages in urban areas. Urban areas are more vulnerable to heatwave events than rural are…
Attrition and morphological analysis of CaCO3 corresponding to oxy-fuel circulating fluidized bed conditions Open
The specific surface area of CaCO3 has always been an essential parameter for various oxy-fuel combustion processes and chemical looping processes. However, the circulating of bed material through the furnace, cyclone and loop-seal in an o…
Quality Management System for an IoT Meteorological Sensor Network—Application to Smart Seoul Data of Things (S-DoT) Open
Meteorological data with a high horizontal resolution are essential for user-specific weather application services, such as flash floods, heat waves, strong winds, and road ice, in urban areas. National meteorological observation networks,…
One-step Oxidation of Total Organic Carbon, Total Nitrogen, and Total Phosphorous using Wet Chemical Oxidation Open
Objective:This study proposed the simultaneous multi-oxidation of total organic carbon, total nitrogen, and total phosphorous using modified wet chemical oxidation method.Methods:The multi oxidation process was based on the dual radical sy…
Study on removal of Se(IV) using Fe-Mn layered double hydroxides and Fe-Mn Dos (double oxides) Open
In this study, Fe-Mn-CO3 layered double hydroxide (LDHs) and Fe-Mn Double oxide (DOs) were synthesized by the co-recipitation methods for Se(IV) removal from aqueous solutions. The Se(IV) adsorption capacities and removal mechanism of Fe-M…
Feasibility Study on Stabilization Technique of Cr(VI)-contaminated Site Open
In this study, a remedial investigation using reductive stabilization was conducted to treat Cr(VI)-contaminated soil. The influences of various operational parameters, including reaction time and the mass of ferrous iron, were also evalua…
Treatment of Selective Sequential Precipitation for Recovering Fe and Al From Mine Water an Abandoned Coal Mine Open
Mine drainage discharged from abandoned mines are causing a lot of pollution. Conventional lime dosing process is generates a lot of waste due to the generation of the sludge in the process. Therefore, this study aims to assess the feasibi…
Influence of Physicochemical Properties on Cesium Adsorption onto Soil Open
Cesium (Cs) generated by nuclear accidents is one of the most hazardous radionuclides because of its gamma radiation and long half-life. Especially, when Cs is exposed on the soil environments, Cs is mainly adsorbed on the topsoil and is s…
