We report on the design, fabrication and performances of a low-noise Nb SQUID sensor for neuromagnetic measurements. The main features of the developed sensor are i) large flux-to-voltage transfer, making the SQUID readout electronics simple, and ii) use of the integrated planar pickup coil to eliminate the environmental magnetic field noises. The magnetic field noise of the developed SQUID sensor is below 5 fT/√Hz at 100 Hz, which is low enough to be used in neuromagnetic measurements.

<P>Excess production of nitric oxide by activated macrophages <I>via</I> inducible nitric oxide synthase leads to the development of various inflammatory diseases. Heme oxygenase-1 expression <I>via</I> activation of nuclear factor-erythroid 2-related factor 2 inhibits nitric oxide production and inducible nitric oxide synthase expression in activated macrophages. Okanin is one of the most abundant chalcones found in the genus <I>Bidens</I> (Asteraceae) that is used as various folk medications in Korea and China for treating inflammation. Here, we found that okanin (possessing the α-β unsaturated carbonyl group) induced heme oxygenase-1 expression <I>via</I> nuclear factor-erythroid 2-related factor 2 activation in RAW264.7 macrophages. 3-Penten-2-one, of which structure, as in okanin, possesses the α-β unsaturated carbonyl group, also induced nuclear factor-erythroid 2-related factor 2-dependent heme oxygenase-1 expression, while both 2-pentanone (lacking a double bond) and 2-pentene (lacking a carbonyl group) were virtually inactive. In lipopolysaccharide-activated RAW264.7 macrophages, both okanin and 3-penten-2-one inhibited nitric oxide production and inducible nitric oxide synthase expression via heme oxygenase-1 expression. Collectively, our findings suggest that by virtue of its α-β unsaturated carbonyl functional group, okanin can inhibit nitric oxide production and inducible nitric oxide synthase expression <I>via</I> nuclear factor-erythroid 2-related factor 2-dependent heme oxygenase-1 expression in lipopolysaccharide-activated macrophages.</P>

Improvement of winter hardiness, lodging resistance and good quality have been recently received more attention by covered barley(Hordeum vulgare L.) breeders than ever in Korea. ‘Hyeyang’, a new covered barley cultivar with early maturing and high yield was developed by the National Institute of Crop Science, RDA in 2010. It was derived from the cross between‘Milyang87’and‘Wolsung8120’with good quality. The initial cross was done in 1999 and the selected line, ‘Iksan432’ (YB4494-B-B-21-2), showed high yield and good quality characteristics under yield trial test from 2008 to 2010. The following is the characteristics of‘Hyeyang’that is characterized as the vernalization of Ⅰ, green leaf, compact spike and long rough awns. The heading date of‘Hyeyang’were similar to‘Olbori’. The culm length was 82 cm which was 6 cm shorter than‘Olbori’. It showed the spike length of 4.3 cm, 798 spikes / m2, 56 grains / spike and 26.7 g for 1,000 grains weight. It showed similar winter hardiness and stronger resistance to barley yellow mosaic virus (BaYMV) compare to‘Olbori’. It showed higher diastatic power 235DP than that of check cultivar, ‘Olbori’. Average yield of ‘Hyeyang’ was 4.44 MT/ha in the regional yield trials carried out in four location at double cropping system in Korea from 2008 to 2010, which was 8 percent higher than ‘Olbori’. ‘Hyeyang’would be suitable for the area above –8℃ of daily minimum temperature in January in Korean peninsula.

Vegetable seeds are one of the most important key factors to determine the way of vegetable’s production, distribution, processing and storage. Unfortunately, because of international exchange crisis in 1997, the most of main Korean seed companies were merged into foreign capitals. Currently, many domestic seed companies are incapable of their own survey and development of vegetable seed markets in foreign countries. To provide valuable seed market information for these companies, China, especially Yunnan and Guangdong provinces in China, was selected. Since China is one of the major vegetable seed importers. Also, Yunnan and Guangdong provinces are the most promising targets to export Korean vegetable seeds. The current status of vegetable production in China was analyzed with consideration of Yunnan and Guangdong provinces. The contents of survey and analysis are covering major vegetable crops’ cultivation area, farm number, cultivation type, production amount, market price, farm income, packaging method, distribution type and amount of seed consumption. And particularly, major horticultural characteristics of leading varieties were presented to assist the development of exportable varieties of domestic seed companies. We assume the results of this study would be practically usable for the development of exportable varieties.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Obesity is a major cause of morbidity and mortality and is associated with risks for type 2 diabetes mellitus, heart disease, metabolic syndrome, hypertension, stroke, and certain forms of cancer. The glutamate decarboxylase 2 (GAD2), insulin-induced gene 2 (INSIG2), ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1), melanocortin 4 receptor (MC4R), fresh touring origination (FTO), and uncoupling protein-1 (UCP-1) genes have been investigated for their association with obesity. Since the A-3826G SNP in the UCP-1 gene was first shown to be the key genetic determinant of obesity and body fat accumulation, many studies have been performed in various populations to measure the association of the G allele of this SNP with obesity phenotypes. The association of the A-3826G SNP with obesity has been controversial, however, suggesting that one SNP does not sufficiently explain the effects of genomic variation on body fat accumulation. In this study, 9 SNPs were newly identified in the 5'-flanking region of the UCP-1 gene by direct sequencing of genomic DNA from 21 Korean subjects, and 6 haplotypes were obtained by SNP genotyping and haplotype reconstruction. According to our haplotype analysis, ht2 of the G allele of A-3826G, was significantly associated with overall fat measures after age and body weight were adjusted. Ht6 of the A allele of A-3826G, was significantly linked to reduced fat accumulation. These results provide an explanation for the controversies that have been reported in many obesity association studies and suggest that haplotype associations between polymorphic loci and neighbor loci that harbor functional sequence variants can be exploited to identify disease-predisposing alleles.

화산분출물 중에서 균질한 화학조성을 가지는 화산유리는 제4기 지형 발달순서 및 지층연대에 많이 사용된다. 비정질 화산유리는 실험실에서 세척, 분리, 감정의 과정을 걸쳐 시료로부터 분리되어 분석된다. 그러나 일련의 과정들 속에서 오류가 발생할 수 있고, 오류로부터 층서대비 및 연대측정에 오차를 발생시킬 수 있으므로 화산유리 연구의 오차 범위를 줄이기 위해, 간단하며 정확한 화산유리 세척, 분리, 감정과정의 이해가 필요하다. 여기에서는 테프라를 통한 정확한 실험을 하기 위해 필요한 올바른 절차에 대해 제안을 해본다. Volcanic glass shard, which shows relatively homogeneous chemical composition in volcanic eruption materials, is used to determine ages of tephra layers and then to correlate tephra layers each other for understanding of evolution of Quaternary geomorphology. For reducing processing errors in age determination and correlation of units, amorphous glass shard should be separated carefully from soil sample through laboratory procedures such as washing, separation, and identification. Introduction of these processes in detail could be reduced errors in tephrochronology by using volcanic glass shard.
