Characterization of Three Complete Mitochondrial Genomes of Hemiculter and Comparative Mitogenomic Analysis of Cultrinae Fishes

Seung Hyun Lee, Sang Ki Kim, Seung Woo Jang, Kyong In Suh et autres

The genus Hemiculter includes closely related freshwater fishes widely distributed across East Asia, and several species are difficult to distinguish using external morphology alone. Mitochondrial markers have been widely used for species identification and phylogenetic inference in fishes, but single-gene approaches may …

Timber resources and management characteristics of economic forestry management areas and other forests in South Korea: post-reforestation challenges

Joungwon You, Seung Hyun Lee, Sun Jeoung Lee, Joo Won Lee et autres

Over the past 50 years South Korea has made considerable strides in economic development and reforestation by converting barren land into dense forests. Despite these achievements, the forestry sector still faces significant challenges in economic viability and resource utilization. Economic Forestry Management …

Grain size distribution and chemistry of the brackish Lake sediment in Korea

ImChul Shin, Tetsuji Akatsuka, Hisayuki Azumi, Lan Ao et autres

To determine the grain size distribution and chemical characteristics of bottom surface sediments in shallow brackish lagoons, we studied sediment samples collected from the entire horizontal lake area and in vertical profiles from three stations in Lakes Youngrang and Hwajinpo, on the …

Comparison of groundwater age models for assessing nitrate loading, transport pathways, and management options in a complex aquifer system

Eun‐Hee Koh, Eunhee Lee, Dugin Kaown, Christopher T. Green et autres

Abstract In an aquifer system with complex hydrogeology, mixing of groundwater with different ages could occur associated with various flow pathways. In this study, we applied different groundwater age‐estimation techniques (lumped parameter model and numerical model) to characterize groundwater age distributions and …

The role of eddies in solute transport and recovery in rock fractures: Implication for groundwater remediation

Seung Hyun Lee, In Wook Yeo, Kang‐Kun Lee, Won Sang Lee

Abstract A better understanding of solute transport and retention mechanism in rock fractures has been challenging due to difficulty in their direct observations in microscale rough‐walled fractures. Six representative troughs in a rough‐walled fracture were selected for microscale observations of eddy formation …

Assessment of the validity of Stokes and Reynolds equations for fluid flow through a rough‐walled fracture with flow imaging

Seung Hyun Lee, Kang‐Kun Lee, In Wook Yeo

Abstract Understanding fluid flow through a rough‐walled fracture is important in many problems such as petroleum and geothermal reservoir exploitation, geological storage of CO2, and sitting of radioactive waste repositories. In order to advance the understanding of fracture flow, we conducted the …

Soil Gas Movement and VOC Concentration Change in Unsaturated Zone with Fluctuating Groundwater Table: Implication for CO₂ Monitoring

Kang‐Kun Lee, W. H. Jeon, Seung Hyun Lee, Seong-soon Lee

Evidences of in Situ Remediation from Long Term Monitoring Data at a TCE-contaminated Site, Wonju, Korea

Seong‐Sun Lee, Hun-Mi Kim, Seung Hyun Lee, JaeHa Yang et autres

The contamination of chlorinated ethenes at an industrial complex, Wonju, Korea, was examined based on sixteen rounds of groundwater quality data collected from 2009 to 2013. Remediation technologies such as soil vapor extraction, soil flushing, biostimulation, and pumping-and-treatment have been applied to …
