We investigated the chemical properties and antioxidant activities of sword bean (SWB) and compared it to soybean (SB) and black soybean (seoritae, BSB). The value of vitamin C, vitamin A, crude fat, and crude protein in SWB was 25.5, 0.37 mg/kg, 1.2, and 25.6%, respectively. The crude fat content (1.2%) in SWB was very low in comparison with those of SB (16.5%) and BSB (16.1%). In 16 free amino acids investigated, the histidine content (9.2%) was high in SWB, followed by SB (3.0%) and BSB (2.9%). Total flavonoid content of SWB (493.2 mg/100 g) was significantly higher than those of SB (71.8 mg/100 g) and BSB (97.5 mg/100 g). Total polyphenol content of SWB (1,152.0 mg/100 g) was not significantly different from that of SB (1,165.7 mg/100 g) but lower than that of BSB (1,298.6 mg/100 g). DPPH radical scavenging activity (SC 50 , 50% scavenging concentration) of SWB was 13.1 µg/mL, whereas that of positive control (α-tocopherol) was 8.3 µg/mL.
There are many factors to influence the amount of terpene at the forest. However, it is poorly understood whether the amount is altered by meteorological factors. In order to study correlation analysis between terpene amount and meteorological(i.e., temperature, humidity, wind speed, solar radiation) and environmental factors(i.e., oxygen, carbonb dioxide) at the artificial coniferous forest of Chamaecyparis obtusa (site 1) and Cryptomeria japonica (site 2) nearby the 1 st reservoir at Mt. Moodeung, the research was executed during April to November in 2011. Forest density at site 1 was 1,692 trees/ha, being occupied with 87.2% of Chamaecyparis obtusa, higher than 925 trees/ha at site 2. Carbon dioxide at site 1 was in the range of 385∼410 ppm in June, similar to at Anmyundo(395 ppm in 2010). Solar radiation has positive correlation with ambient temperature and inversely negative with relative humidity. Main species of terpene released were α -pinene, camphene, β-pinene, cymene, δ-limonene and camphor at two sites and terpene was more effluent at spring and summer than at fall. The large amount of terpene was emitted in the afternoon than in the morning under the influence of the wind speed and the topographical property. The terpene amount has positive correlation with relative humidity and oxygen, and negative with wind speed and soil temperature. Because correlations of α-pinene and other terpene materials showed statistically significant within p=0.01. α-pinene could be suggested as the basic material in explaining the amount of other terpene materials.
This survey was conducted to monitor the safety of red ginseng products in Gwangju, in 2010. Among 100 samples, 37 were beverages, 5 were functional health foods on the market, and 58 were beverages from a tailor-made shop. All samples were negative for coliform bacteria. Aerobic plate counts were detected from 13 samples in the 58 tailor-made products but not detected in the other types of products. Benzoic acid was detected in 5 samples (range, 19.2-543.0 mg/kg). Among heavy metals, lead was detected, ranging from 28.8-62.3 µg/kg, cadmium, from 1.15-4.18 µg/kg, and mercury from 0.10-0.18 µg/kg. Benzopyrene was not detected in any samples. Ginsenoside Rg1 and Rb1 were detected in 0.1-23.4 mg/90 mL of beverages and 12.1-66.8 mg/90 mL of functional health foods. These results indicate that red ginseng products are safe in terms of microbial contaminants and hazardous chemical compounds such as heavy metals and benzopyrene.
In the paper, we describe the design and implementation of middleware for NCW, which provides automatic military operation services based on the inferred battlefield contexts using ubiquitous computing. Middleware for NCW is composed of two layers which support automatic military operations by providing a decision support system using context-awareness service in ubiquitous computing for various military applications. For the traditional Platform Centric Warfare model, we have developed middleware consists of two layers for Network Centric Warfare based on ubiquitous computing: Context-aware Reasoning Layer and Ubiquitous Main Layer. Context-aware Reasoning Layer provides the intelligent context by processing data obtained through military sensor network. Executing specific military operations, Ubiquitous Main Layer generates proper military operations and controls military devices which makes applications or services used everywhere such as display, Army PC, or MSP (Military Smart Phone) with the choice of a number of input devices by provides the automatic computing environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
