About the Lab
Professor Sin-Woo Lee's research spans environmental science, sustainable manufacturing, and geochemical analysis, with a strong focus on isotopic tracing for pollution source identification and green productivity assessment. His lab investigates environmental contaminants such as MTBE and petroleum hydrocarbons using stable isotope signatures to trace origins and support remediation strategies. Additionally, the lab explores sustainable industrial practices, including green productivity in manufacturing and efficient food processing techniques like salting and dehydration. The integration of analytical chemistry with real-world environmental challenges defines the lab’s interdisciplinary approach.

15본 연구는 대학에서 플립드 러닝 수업을 수강한 학생들의 학습 경험을 파악하기 위해 질적 연구로 수행되었다. 연구의 목적은 대학생들이 어떤 배경에서 플립드 러닝 수업을 선택하고, 온라인과 오프라인으로 구성된 각각의 수업을 학습하는 과정에서 어떠한 경험하는지 밝히는 것이다. 이에 플립드 러닝이 활성화 되어 있는 국내 A대학교를 사례로 하여, 플립드 러닝 수업을 들은 경험이 있는 학생 7명을 대상으로 심층면담, 온라인 커뮤니티를 관찰, 연구자의 성찰일지를 바탕으로 연구를 진행하였다. 연구결과 대학생들은 플립드 러닝 수업에 대해 잘 모르고 있으며, 학점 대비 수업시간이 짧다는 것에만 매력을 느꼈다. 수업형태라는 것에 별 관심이 없었다. 온라인 수업은 제 때 듣지 않거나, 복습용의 의미가 컸으며, 현장감의 부재를 체험했다. 오프라인 수업에서는 동료 학생들의 구성이 중요하며, 커뮤니케이션 능력이 향상되었고, 교수와 소통하는 기회가 많아졌다고 진술했다. 이러한 경험을 종합하면 중요한 것은 방법의
Magnesium is an important element in both the lithosphere and biosphere. Many previous studies have focused on directly tracing Mg cycles using Mg isotopes, and various methods for Mg purification and isotopic measurement have been previously elucidated. Here, we present a newly developed Mg separation method, along with a verification of the method by measuring the Mg isotope composition (expressed as δ26Mg relative to DSM-3) of various standard materials. All matrix cations causing significant
This study measures and decomposes green productivity growth of Korean manufacturing industries between 2004 and 2010 using the Malmquist-Luenberger productivity index. We focus on differences in the measures of productivity growth by distinguishing carbon emissions from either end-user industries or the electricity generation industry. Empirical results suggest three main findings. First, the efficiency of total emissions is higher than that of direct emissions except for the shipbuilding indus
In this study, salting conditions and dehydration methods were investigated. Salting time, concentration and temperature could be considered to variables in salting conditions. The diffused salt amounts to beef jerky depending on time are sharply increased in two hours. This result is caused by the difference decrease of concentration gradient between bulk solution and beef jerky. The increase of salting concentration and temperature resulted also in the increase of a diffused salt. The deeper b
Since the late 1990s, methyl tert-butyl ether (MTBE) contamination in groundwater aquifers has become a serious concern in many countries. This study focused on the carbon and hydrogen isotopic compositions of MTBE reagents produced by six manufacturers from three regions, to investigate the potential of utilizing stable isotopes in tracing the production origin of MTBE. The carbon and hydrogen isotopic compositions (δ13C and δD) of MTBE ranged from −31.0% to −26.4% and −101% to −54%, respective
RATIONALE: Leakage of gasoline and diesel from underground tanks has led to a severe environmental problem in many countries. Tracing the production origin of gasoline and diesel is required to enable the development of dispute resolution and appropriate remediation strategies for the oil-contaminated sites. METHODS: We investigated the bulk and compound-specific isotopic compositions of gasoline produced by four oil companies in South Korea: S-Oil, SK, GS and Hyundai. The relative abundance of

This paper measures the technical inefficiency and the shadow price of Korean fossil-fuel generation companies (GENCOs) between 2001 and 2016 at the firm-level. To obtain robust empirical results, this study employs both commonly used deterministic and stochastic estimation methods. The empirical results are as follows: the inefficiency estimates are approximately 0.09 (deterministic) and 0.08 (stochastic); the estimates of CO 2 shadow price, in KRW/tCO 2 , are 82,758 (deterministic) and 49,830
Soil properties and heavy metal (HM) concentrations in the field soils where balloon flowers (Platycodon grandiflorum, BF) were cultivated, were investigated together with HM (Cd, Cu, Pb, and Zn) accumulation by the BF roots. Basically, in most soils examined (51-97% among 65 samples), the chemical properties including soil pH, organic matter, available-P, and exchangeable cation contents appeared to be lower than the optimal ranges for balloon flower cultivation. There were no samples exceeding
