… The goal of the current meta-analysis is to understand the overall effectiveness of CSCL in STEM education while attending to some of the … levels can also significantly moderate outcomes in CSCL, although the examination of learning domains...

Large-scale quantitative analysis of painting arts.

Scientific reports

Kim D, Son SW, Jeong H.
PMID: 25501877
Sci Rep. 2014 Dec 11;4:7370. doi: 10.1038/srep07370.

Scientists have made efforts to understand the beauty of painting art in their own languages. As digital image acquisition of painting arts has made rapid progress, researchers have come to a point where it is possible to perform statistical...

PURPOSE: Prognostic factors for distal bile duct cancer are contentious. This study was conducted to analyze the prognostic factors of distal bile duct cancer after surgery with the aim of identifying those associated with diminished survival.METHODS: Two hundred forty-one...

Babinet-inverted optical Yagi-Uda antenna for unidirectional radiation to free space.

Nano letters

Kim J, Roh YG, Cheon S, Choe JH, Lee J, Lee J, Jeong H, Kim UJ, Park Y, Song IY, Park QH, Hwang SW, Kim K, Lee CW.
PMID: 24801373
Nano Lett. 2014 Jun 11;14(6):3072-8. doi: 10.1021/nl500062f. Epub 2014 May 06.

Nanophotonics capable of directing radiation or enhancing quantum-emitter transition rates rely on plasmonic nanoantennas. We present here a novel Babinet-inverted magnetic-dipole-fed multislot optical Yagi-Uda antenna that exhibits highly unidirectional radiation to free space, achieved by engineering the relative phase...

Draft Genome Sequence of a Diazotrophic, Plant Growth-Promoting Rhizobacterium of the Pseudomonas syringae Complex.

Genome announcements

PMID: 27660794
Genome Announc. 2016 Sep 22;4(5). doi: 10.1128/genomeA.01023-16.

We report here the draft genome sequence of Pseudomonas syringae GR12-2, a nitrogen-fixing, plant growth-promoting bacterium, isolated from the rhizosphere of an Arctic grass. The 6.6-Mbp genome contains 5,676 protein-coding genes, including a nitrogen-fixation island similar to that in...

Reconfigurable van der Waals Heterostructured Devices with Metal-Insulator Transition.

Nano letters

Heo J, Jeong H, Cho Y, Lee J, Lee K, Nam S, Lee EK, Lee S, Lee H, Hwang S, Park S.
PMID: 27704847
Nano Lett. 2016 Nov 09;16(11):6746-6754. doi: 10.1021/acs.nanolett.6b02199. Epub 2016 Oct 05.

Atomically thin two-dimensional (2D) materials range from semimetallic graphene to insulating hexagonal boron nitride to semiconducting transition-metal dichalcogenides. Recently, metal-insulator-semiconductor field effect transistors built from these 2D elements were studied for flexible and transparent electronics. However, to induce ambipolar...

Genome Announc. 2015 Oct 01;3(5). doi: 10.1128/genomeA.01121-15.

We report the 4.0-Mb draft genome sequence of Bacillus amyloliquefaciens (syn. Bacillus velezensis) KCTC 13012, which exhibits a broad spectrum of antagonistic activity against bacteria and fungi and promotes plant growth as well. The genome contains an array of...

Carrier localization in In-rich InGaN/GaN multiple quantum wells for green light-emitting diodes.

Scientific reports

Jeong H, Jeong HJ, Oh HM, Hong CH, Suh EK, Lerondel G, Jeong MS.
PMID: 25792246
Sci Rep. 2015 Mar 20;5:9373. doi: 10.1038/srep09373.

Carrier localization phenomena in indium-rich InGaN/GaN multiple quantum wells (MQWs) grown on sapphire and GaN substrates were investigated. Temperature-dependent photoluminescence (PL) spectroscopy, ultraviolet near-field scanning optical microscopy (NSOM), and confocal time-resolved PL (TRPL) spectroscopy were employed to verify the...
