A new annual dose evaluation system called E-DOSE has been developed. The system is based on the methodology of the previous version, K-DOSE60, which uses the dose evaluation methods of the International Commission on Radiological Protection (ICRP-60). However, E-DOSE is coded in ABAP to be compatible with the KHNP’s enterprise resource planning (ERP) system, SAP. This allows E-DOSE to use the real-time data from SAP, which minimizes the need for user intervention. The socio-environmental data, which was previously managed by the staff of each plant sites, can now managed in the system in a centralized manner. This is a significant improvement over the previous system, as it reduces the risk of errors and makes it easier to track and manage data. The system also automatically generates the reports required by regulations. EDOSE is expected to minimize the occurrence of human errors in preparing and managing the input data. This is because the system uses the data from SAP, which is less prone to errors than manually entered data. Additionally, the automatic generation of reports reduces the risk of errors in report preparation. E-DOSE is also expected to improve work efficiency. This is because the system automates many of the tasks involved in annual dose evaluation, such as data entry, calculation, and report generation. Overall, E-DOSE is a significant improvement over the previous annual dose evaluation system. It is more efficient, accurate, and user-friendly.
Ostrea denselamellosa and Eriocheir japonica samples were collected from the Seomjin River in 2019 as part of the “Research of Host-Associated Bacteria” research program. Almost 200 bacterial strains were isolated from the O. denselamellosa and E. japonica samples and subsequently identified by 16S rRNA gene sequencing. Among the bacterial isolates, ten strains possessed greater than 98.7% sequence similarity with published bacterial species that had not previously been recorded in Korea. These species were phylogenetically diverse, belonging to three phyla, four classes, seven orders, and eight genera. At the genus and class level, the previously unrecorded species belonged to Pseudoalteromonas, Aliivibrio, Rheinheimera, Leucothrix, and Shewanella of the class Gamma-proteobacteria, Olleya of the class Flavobacteriia, Algoriphagus of the class Cytophagia, and Lactococcus of the class Bacilli. The previously unrecorded species were further characterized by examining their Gram staining, colony and cell morphology, biochemical properties, and phylogenetic positions.
This study was intended to investigate the characteristics of muffins prepared with allulose which is low-calorie and physiologically functional rare sugar. Volume and specific volume of muffins increased significantly with allulose addition, but not with its contents. Muffin heights also increased as allulose was added more. Baking loss rate and moisture contents were not significantly different among samples. Allulose seemed to have nearly same water holding capacity with sucrose. Lightness of muffin crust and crumb both decreased, but redness and yellowness increased according to allulose, the reducing sugar addition by Maillard reaction. In the texture profile analysis, Hardness of AL100 was higher significantly (p<0.05) and springiness, cohesiveness and fracturability increased according to the allulose contents. In the sensory evaluation, AL0 was the sweetest and AL0 and AL25 got higher overall acceptance score. Physical characteristics were not different (p<0.05) among AL0, Al25 and AL50. As a result, 25% sucrose substitution with allulose can provide low-calorie, anti-hyperglycemic and tasty muffin.
The dynastid beetle Allomyrina dichotoma has been used as a herbal medicine. Recently, we performed de novo RNAsequencing of Allomyrina dichotoma and identified several antimicrobial peptide candidates based on in silico analysis.Among them, cationic antimicrobial peptide, Allomyrinasin, was selected and we assessed the anti-inflammatory activitiesof Allomyrinasin against mouse macrophage Raw264.7 cells. The results showed that Allomyrinasin decreased the nitricoxide production of the lipopolysaccharide-induced Raw264.7 cells. In addition, quantitative RT-PCR, ELISA and Westernblot analysis revealed that Allomyrinasin reduced cytokine expression levels in the Raw264.7 cells. Taken together, thesedata indicated that Allomyrinasin had anti-inflammatory activity in the lipopolysaccharide-induced Raw264.7 cells.
Although the grasshopper Oxya chinensis sinuosa has long been used as a food in Korea, there is little data on itsfunctional effects. Thus we prepared and analyzed total RNA from the whole body of adult Escherichia coli non-immunizedand immunized Oxya chinensis sinuosa strains. Using an Illumina Hiseq sequencer, we generated a total of 66,555 pooledtranscriptome and singletons with and without Escherichia coli immunization, respectively. Then, we performed in silicoanalysis of the Oxya chinensis sinuosa transcriptome, using bioinformatics tools for screening putative antimicrobial peptides(AMPs) and 38 AMPs were finally selected and tested their antimicrobial activity of Gram positive, Gram negative bacteriaand antifungal activity with radial diffusion assay. As a result, 5 out of 38 AMPs showed the highest antimicrobial activityand antifungal activity against microbes and it also evidenced with no hemolytic activity.
The purpose of this study was performed to determine the whitening effect of organic solvent extracts from the centipede, Scolopendra subspinipes mutilans. We prepared different concentrations (50%, 70% and 100%) of ethanol, methanol, 100% ethyl acetate and water extracts. We tested melanin inhibitory effect and tyrosinase activity using B16/F10 melanoma cell. As a result, treatment of organic solvent extracts is decreased the biosynthesis of melanin and tyrosinase activity to 30~60%. Especially the 70% ethanol extracts was the most effective in B16/F10 melanoma cells. In the study on melanogenic protein expression, 70% ethanol extracts of Scolopendra subspinipes mutilans blocked glycosylation of tyrosinase. Therefore this result suggests that 70% ethanol extracts could be developed as a skin whitening agents.
Wet noodles with different percentages of amaranth powder were prepared and their cooking characteristics were evaluated. The cooking quality, mechanical textural properties, and a sensory evaluation was conducted with the prepared noodles. Cooked noodle properties, weight, and volume decreased as amaranth content of the wheat flour increased, whereas turbidity and water absorption of the soup increased, except for cooked noodles with 30% amaranth. The L-value of the raw and cooked noodles decreased significantly with increasing amaranth powder content. The a- and b-values increased with increasing amounts of added amaranth powder. The L-value of the raw and cooked noodles with amaranth was significantly lower than that of the control, and the a-value was lower than that of the control, whereas the b-value was higher than that of the control for both raw and cooked noodles. A texture profile analysis of the raw noodles showed significantly higher levels of hardness, cohesiveness, gumminess, chewiness, and springiness in the amaranth noodles compared to those in the control; the values for adhesiveness were not significantly different. The hardness, gumminess, springiness, and chewiness of the cooked noodles decreased in proportion to the quantity of added amaranth. The springiness, adhesiveness, and cohesiveness of cooked noodles with amaranth decreased slightly. Overall, the results of a sensory evaluation revealed that the cooked noodles with amaranth had higher values than those of the control, except for overall acceptability. Amaranth added at a concentration of up to 30% increased brown color and the peculiar amaranth odor. In a sensory evaluation, cooked noodles with 20% amaranth powder were preferred more than the other noodles for overall acceptability.
Thermally processed vegetables have long been considered to have lower nutritional values compared to fresh produce. This consideration is based on the fact that ascorbic acid(vitamin C) or other thermolabile compounds may lose their activity due to oxidation or by consequence of leaching into the water during home cooking or industrial processing, such as by blanching. In this study, major agricultural products such as carrots, broccoli, and potatoes were exposed to steam treatments of different types. Then, changes in color and levels of ascorbic acid, carotene, and moisture in the fresh and steam processed vegetable samples were measured and evaluated. The results clearly showed that steam-processing using a natural convection type method was superior to the other treatments in terms of quality, including color and nutrient retention, among all the vegetables tested.
Rice bran is byproducts of the hulling of rice, an important food resource in Korea. Various studies have been reported immune-enhancing effects of rice bran cultured with Lentinus edodes. In particular black rice bran contains anthocyanin, and the effects of antioxidant have been reported. The objective of the this study was to investigate the possible immuneenhancing effects of black rice bran substance extracted from a submerged culture of Lentinus edodes with black rice bran (crude fermentation-polysaccharide, CFP) and products(crude fermentation-polysaccharide-S. cerevisiae CFP-S, crude fermentationpolysaccharide- L. gasseri, CFP-L) which are of secondary fermentation of by using Saccharomyces cerevisiae and Lactobacillus gasseri in the Blab/c male mice. We found that supplementation of CFP, CFP-S and CFP-L enhanced macrophage and splenocyte proliferation compared to the control group(NC) in mice. Also, we measured the concentration of cytokines(IFN- γ, TNF-α, IL-6) secreted by activated macrophage and splenocyte. The results of the experiment are that supplementation of CFP and CFP-S increased the macrophage and splenocyte proliferation compared to the control group but supplementation of CFP-L decreased the splenoyte proliferation compared to the control group(without mitogen and treated with LPS). When macrophage and splenocyte were stimulated by CFP and CFP-S supplementation, it was increased IFN-γ, TNF-α and IL-6 concentration compared with the control group. These results suggest that the capacity of CFP and CFP-S seem to act as a potent immune modulator causing augmentation of immune cell activity, and enhance the immue function through regulating cytokine production capacity by activated macrophage and splenocyte in mice.

Fluorescence in situ hybridization (FISH) is a powerful tool for the detection of DNA sequences in the specific region of the chromosomes. As well as for the integrated physical mapping, FISH karyotype analysis has to be preceded. The detailed karyotypes of two onion cultivars, which are resources for onion genome sequencing project (‘Eumginara’ and ‘Sinsunhwang’), were constructed based on triple color fluorescence in situ hybridization (FISH) using 5S rDNA, 45S rDNA, and tandem repeat sequence. All used our materials showed 2n=2x=16 with x=8 as basic chromosome number. 5S rDNAs were located on 4 loci in one pair of interstitial region of short arm chromosome in both onion cultivars. Two pairs of 45S rDNAs were positioned in distal region of short arm chromosome in ‘Eumginara’. Otherwise 5 loci of 45S rDNAs were located in distal region of two pairs of short arm chromosome in ‘Sinsunhwang’. Among them, two signals of 45S rDNAs were co-localized in distal part of short arm and long arm chromosome, respectively. In case of tandem repeat sequence was detected on telomeric region of 8 pairs of chromosomes except on 45S ribosomal DNA sites. These results will provide a valuable background for physical mapping and help to further more understand the genome sequencing project in Allium cepa.
Ilpumbyeo, a japonica rice cultivar which is known to have premium eating-quality, and high yield potential, but susceptible to rice blast disease was studied whether it has any specific rice blast resistance gene/QTL. Using CAPS markers which were develo
