To date, no direct measurements of primary production were taken in the Amundsen Sea, which is one of the highest primary productivity regions in the Antarctic. Phytoplankton carbon and nitrogen uptake experiments were conducted at 16 selected stations using a 13C–15N dual isotope tracer technique. We found no statistically significant depletions of major(More)

The rapid melting of glaciers as well as the loss of sea ice in the Amundsen Sea makes it an ideal environmental setting for the investigation of the impacts of climate change in the Antarctic on the distribution and production of mesozooplankton. We examined the latitudinal distribution of mesozooplankton and their grazing impacts on phytoplankton in the(More)
The purpose of this study was to report variations of the cubital superficial vein patterns in the Korean subjects, which was investigated by using venous illuminator, AccuVein. The 200 Korean subjects were randomly chosen from the patients and staff of the Keimyung University Dongsan Medical Center in Daegu, Korea. After excluding the inappropriate cases(More)
BACKGROUND This study was conducted to determine the early cardiac valvular changes in young male ankylosing spondylitis (AS) patients. METHODS A total of 70 AS patients on treatment without clinical cardiac symptoms were divided into group I (< 10 years, n = 50) and group II (≥ 10 years, n = 20) depending on their disease duration after first diagnosis.(More)
BACKGROUND Although patients may present with typical chest pain and exhibit ischemic changes on the cardiac stress test, they are frequently found to have a normal coronary angiogram. Thus, we wanted to determine which procedures should be performed in order to make an adequate diagnosis of the cause of chest pain. METHODS 121 patients (males: 42, 34.7%)(More)
