Detailed morphological documentation is provided for established Proschkinia taxa, including the generitype, P. bulnheimii, and P. complanata, P.

Complete mitochondrial genome of a rare diatom (Bacillariophyta) and its phylogenetic and taxonomic implications.

We obtained the complete mitogenome of sp. strain SZCZR1824, a strain belonging to a poorly known diatom genus with no previous molecular data. This genome is 48,863 bp long, with two group I introns in and three group II introns in 1.

Work Engagement in South Korea.

This study aims to validate Korean versions of the 9-item Utrecht Work Engagement Scale, testing for its factor pattern validity through Exploratory Factor Analysis and Confirmatory Factor Analysis, reliability, and convergent and discriminant validity. The 9-item Utrecht Work Engagement Scale was translated according to the guidelines of the International Test Commission and tested with two Korean samples. First, the Exploratory Factor Analysis found that both two-factor and three-factor solutions were viable options with the first sample.

Influence of the tidal front on the three-dimensional distribution of spring phytoplankton community in the eastern Yellow Sea.

Hydrographic observation and biological samplings were conducted to assess the distribution of phytoplankton community over the sloping shelf of the eastern Yellow Sea in May 2012. The concentration of chlorophyll a was determined and phytoplankton was microscopically examined to conduct quantitative and cluster analyses. A cluster analysis of the phytoplankton species and abundance along four observation lines revealed the three-dimensional structure of the phytoplankton community distribution: the coastal group in the mixed region, the offshore upper layer group preferring stable water column, and the offshore lower layer group.
