Large-strain monotonic and cyclic loading tests of AZ31B magnesium alloy sheets were performed with a newly developed testing system, at different temperatures, ranging from room temperature to 250 °C. Behaviors showing significant twinning during initial in-plane compression untwinning in subsequent tension slightly above recorded. Strong yielding asymmetry nonlinear hardening behavior also revealed. Considerable Bauschinger effects, transient behavior, variable permanent softening...
The East/Japan Sea (hereafter, the East Sea) is highly dynamic in its physical phenomena and biological characteristics, but it has changed substantially over last several decades. In this study, a recent decadal trend of primary productivity was analyzed based on Moderate-Resolution Imaging Spectroradiometer (MODIS)-derived monthly values to detect any long-term change. daily productivities averaged using from 2003 2012 were 719.7 mg·C·m−2·d−1 (S.D. ± 197.5 mg·C·m−2·d−1, n = 120) 632.3...
Understanding the responses of marine organisms to environmental changes at their distribution limits is crucial for predicting climate-change associated habitat changes. This study analyzed effect sea surface temperature (SST) on temporal Chum salmon ( Oncorhynchus keta ) in eastern and southern coastal waters Korea (ESCK) limit North Pacific. The ESCK adjacent rivers was statistically compared based three SST types (T1–T3). were first caught northern then area, with riverine migration...
No ideal serum markers for screening colorectal cancer (CRC) have been identified. The aim of this study was to determine the usefulness endothelial cell‐specific molecule‐1 (ESM‐1) as a marker CRC. Illumina microarray carried out search CRC‐related biomarkers. cDNA detected that ESM‐1 one overexpressed genes in Overexpression mRNA confirmed tissues CRC by RT‐PCR and real‐time PCR. Immunohistochemical staining showed strong expression cytoplasm tumor cells. human with found Western blot...
The decline in walleye pollock (Gadus chalcogrammus) stocks Korean waters is a major concern for fishery conservation and management. However, the causes mechanisms of this collapse remain unclear. This study investigated complex dynamics influencing abundance pollocks East Sea Korea over several decades, by analyzing data from long-term changes biological factors including composition length sex, catch, oceanographic condition. Prior to mid-1980s, catch ratio juveniles was higher than that...
Long-term variations (1975–2002) in climatology of marine environmental parameters, Antarctic krill, Euphausia superba , and the pelagic tunicate, Salpa thompsoni were compared within Atlantic Sector Southern Ocean. Sea water temperature top 400 m increased at a rate 0.020–0.030 ° C ⋅ yr −1 which was accompanied by dissolved oxygen decline. Top 100 layer became fresher with lower concentrations phosphates nitrates, while subsurface layers (200–400 m) both salinity nutrients showed small...
Largehead hairtail ( Trichiurus japonicus ) is one of the most commercially important fishes in western North Pacific. To identify dietary changes across ontogeny and seasons, we investigated its stomach contents stable isotope signatures (δ 13 C δ 15 N) South Sea Korea. The index relative importance revealed that composition largehead consisted mainly Pisces (1.6%–84.8%) Euphausiacea (3.0%–93.0%). However, proportions items differed by season anal length (ALs), suggesting a trophic...
This paper demonstrates the fabrication and performance of a micro-thermoelectric gas sensor for an effective inexpensive analysis system. The proposed was fabricated by using surface micromachining technique. sensing mechanism, consisting thermoelectric material novel metal catalyst, on highly thermally resistive layer reduced heat transfer to substrate allowing simple process. detects target species measuring reaction catalytic between catalyst Cu–Bi thermopiles. occurs only hot junction...

It has traditionally been prized Chinese folk medicine for human well-being. Because similarity chemical structure adenosine, cordycepin focused on...
The climate-induced changes in marine fishery resources South Korea have been a big concern over the last decades. climate regime shift has led to not only change dominant resources, but also decline landings several species. habitat suitability index (HSI) widely used detect and forecast fishing ground formation. In this study, catch data of Todarodes pacificus (Japanese Common Squid) satellite-derived environmental parameters were estimate HSI for T. around Korea. More than 80% total was...
Recent global climate change often leads to poleward expansions of habitat range marine organisms in response increasing water temperature at high latitude. This study investigated latitudinal distribution patterns Turbo sazae from 2009 2018 along the southern and eastern coasts Korea verify whether gradual increases seawater East Sea/Sea Japan (hereafter East/Japan Sea) accelerate changes geographic T. sazae. Between 2018, underwater SCUBA surveys were conducted 19 subtidal rocky shore...
Walleye pollock ( Gadus chalcogramma ) caught in the Korean fishing area dramatically decreased late 1980s. To investigate potential impact of 1980s climate regime shift on collapse catch, we developed a three-dimensional hydrodynamic model with data assimilation and particle tracking model. Data-assimilated reanalysis showed that sea surface temperature increased by approximately 2°C spawning The suitable East Bay due to warming Spawned eggs walleye were tracked using for 30 days January...
