  • Growth characteristics and crude protein content of soybean sprouts cultivated with extracts of some Korean herb medicines for 4 days were investigated. Extracts of Korean herb medicines were utilized and adjusted to 100 ppm, 200 ppm, 300 ppm and 400 ppm as culturing water of soybean sprouts. Of Korean herb medicines tested, extract of Panax ginseng was most effective to increase of weight and length of soybean sprouts, followed by Glycyrrhiza glabra. Extracts of Angelica gigas and Cnidium officinale were similar with that of control group. Extract of Coptidis japonica inhibited the growth of soybean sprout. Optimal concentrations of extracts of Glycyrrhiza glabra and Panax ginseng for growth of soybean sprout were 100 ppm and 200 ppm, respectively. Weight of soybean sprout cultivated with extract of Panax ginseng (PGE) was increased to 7.2%(wet basis) as compared with that of control group. Length of soybean sprouts cultivated with 200 ppm of PGE was accelerated to 32% and increased to 50% in soybean sprout cultivated for 3 days. Crude protein contents of soybean sprout cultivated with extract of Angelica gigas or Panax ginseng was slightly increased according to cultivation period. In Cnidium officinale group, crude protein contents was increased at a 300∼400 ppm concentration and 4 days of cultivation.

  • The goal of this study was to evaluate the anti-obesity effect of radish leaf extracts (MU-C) and radish leaf extracts with 3% citric acid (MU-CA) in a high-fat diet (HFD)-induced C57BL/6 mice. The effects of radish leaf extracts on adipogenesis were also investigated using 3T3-L1 adipocytes. As determined by Oil red O staining, MU-C inhibited adipogenesis in 3T3-L1 adipocytes. Four-week-old male C57BL/6 mice were fed an HFD for 6 weeks and then treated with radish leaf extracts (500 mg/kg, p.o.) for 6 weeks. Then, the serum levels of Aspartate aminotransferase, Alanine aminotransferase, Total cholesterol, Triglyceride and low-density lipoprotein cholesterol in the mice were measured using an automatic chemical analyzer and enzyme-linked immunosorbent assay. Administration of MU-C significantly reduced the fat weight when compared with HFD controls. As confirmed by histopathologic analysis, adipose tissue size markedly decreased in mice treated with MU-C. Therefore, this study could provide a basis for investigating the clinical use of MU-C as an agent for preventing obesity.

  • To investigate whether genistein regulates menopause-induced obesity, it was studied the effects of genistein on anti-obesity effects in female ovariectomized (OVX) mice, an animal model of postmenopausal women. 7-week-old female mice (C57BL/6J) were randomly divided into three groups. All the animals received a high fat diet or a high fat diet supplemented with genistein for 8 weeks and variables and determinants of obesity were measured. The OVX mice had significantly higher body weight and adipose tissue mass than sham mice. However, genistein supplementation reduced body weight, adipose tissue mass, and adipocyte size of OVX mice. The OVX mice treated with genistein had significantly lower levels of serum triglycerides and total cholesterol than the vehicle-treated OVX mice. Lipid accumulation in liver was also markedly decreased by genistein in OVX mice. The results suggest that genistein can effectively prevent adiposity, adipocyte phertrophy, and llipid disorders caused by ovariectomy. Moreover, this study may contribute to the alleviation of metabolic syndrome, including obesity and hyerlipidemia in postmenopausal women.

  • Salicornia herbacea L. is an annual herb that grows in salt marshes and salt fields along the seashores. It is also commonly used as a folk remedy in Korea. The objective of this study was to investigate the beneficial effects of Salicorrnia herbacea L. (SH) hot water extract on obesity. Five-week old male Sprague-Dawley rats (n=36) were divided into two groups and provided either a normal fat diet (11.5% fat from kcal) or a high fat diet (40.5% fat from kcal) for 6 weeks to induce obesity. Then, rats were blocked into six groups of six mice each and provided either a diet containing SH (0.5% of diet; g/kg) or a normal diet for another 6 weeks. Final body weights were significantly reduced when rats were fed SH among the high fat diet groups (HNS and HHS). Serum triglyceride concentrations significantly decreased in every group provided SH. HDL-cholesterol concentrations significantly increased in SH-fed groups among the high fat diet groups. Further, atherogenic index significantly decreased when rats were fed SH diet (HHS). There were no differences in LDL-cholesterol between the high fat diet groups, and glucose concentrations decreased when rats were fed SH diet (HNS). These results indicate that dietary intake of Salicornia herbacea L. hot water extract might have beneficial effects on obesity by reducing body weight, fat weights, and improving blood lipid profile.

  • A fault is one of the critical factors that may lead to a possible ground collapse occurring in construction site. A fault core, however, possibly acting as a failure plane in whole fault zone, is composed of fractured rock and gouge nonuniformly distributed and thus can be characterized by its wide range of shear strength which is generally acquired by experimental method for stability analysis. In this study, we performed direct shear test and grain size distribution analysis for 62 fault core samples cropped from 12 different spots located in the vicinity of Kyongju and Ulsan, Korea. As a result, the range of shear strength representing the characteristics of fault cores in the study regions is determined with regard to vertical stress using a regression analysis for experiment data. The weight ratio of gravels in the samples is proportional to the shear strength and that of silt and clay is in inverse proportion to the shear strength. For most samples, the coefficient of determination is over 0.7 despite of inhomogeneity of them and consequently we determined the lower limit and upper limit of the shear strength with regard to the weight ratio by setting the confidence interval of 95%.

  • WIM(Weigh-In-Motion) is the system measuring the weight of the vehicle with a high-speed. In the existing WIM system, vehicle weight is measured based on the constant speed and the error ratio has 10%. However, because of measuring the driving pattern, that is abnormal driving pattern which is like the acceleration and down-shift of the drivers, it has the error ratio which is bigger than the real. In order to it reduces the error ratio of WIM system, the improved WIM system needs to find the abnormal driving pattern. In order to reducing the error ratio of these WIM systems, the improved WIM system can find abnormal driving patterns. In this paper, the improved WIM system which analyzes the abnormality driving pattern influencing on the error ratio of WIM system of an existing and minimizes the error span is designed. The improved WIM system has the multi step loop structure of adding the loop sensor to an existing system. In addition, the measure function defined as an intrinsic is improved and the weight measured by the abnormal driving pattern is amended. The analysis of experiment result improved WIM system can know the fact that the error span reduces by 8% less than in the existing the maximum average sampling error 22.98%.

  • Morphometrical data for diploid and induced triploid cherry salmon, Oncorhynchus masou were analyzed prior to the spawning season to compare their commercial values. The following traits were measured with the diploids and induced triploids : ungutted and gutted body weight; body length; dressing percentage; condition factor; gonad weight and gonad index; belly thickness; viscera weight; viscera index; body circumference at the pelvic, dorsal and anal fins; area of the cross sections at the pelvic and dorsal fins; two belly thickness traits measured on each cross section; total height, height and width of each cross section; three body shape traits; and nine cross section shape traits. Body length and body weight of diploids were larger than those of induced triploids and dressing percentage, gonad weight, gonad index, viscera index, and liver index were also larger in diploids. However, induced triploids showed higher values in one belly thickness trait and some section shapes than diploids. Differences in body traits were due to the sterility of induced triploids. Therefore, induced triploid cherry salmon appears to have greater potentials for the commercial values than their diploids.
