To investigate the effects of Protaetia. brevitarsis extracts on the protection against liver damage by carbon tetrachloride($CCl_4$) in rat, two kinds of experiment were performed, firstly by the primary hepatocyte culture and secondly by the animal feeding. The primary hepatocyte culture with the extracts of P.brevitarsis showed significantly low activities of GPT, bile acid, and bilirubin, indicating an excellent protective effect against liver damage by $CCl_4$. Especially, below molecular weight 1,000 blew the water to have 32.1% recovery degree. In the seconde experiment, serum GPT activity was significantly decreased in water fraction of P. brevitarsis compared to $CCl_4$ treatment by 98.2%. Serum concentration of bile acid and bilirubin were tended to increased by $CCl_4$ treatment, but water fraction of P. brevitarsis and silymarin recovered the level. These consistent results in vitro and in vivo suggest that the extracts of P. brevitarsis may have strong protective effects against liver damage induced by the potential toxicants such as $CCl_4$.

This study aimed to verify the effects of a 4-week program of ankle-strengthening exercise and toe-taping walk exercise on the basic lower body strength and walking to examine the benefits of the two exercises. The subjects involved 30 women in their 20s enrolled in university A. The subjects were equally divided into three groups - ankle-strengthening exercise group, toe-taping walk exercise group, and control group. The subjects were instructed to massage and do ankle-strengthening exercises using a towel, massage ball, and CRT, for 60 minutes, 3 times a week. They also taped their hallux valgus using a kinesiology tape and walked for 20 minutes with white tape applied. To sum up, the 4-week ankle-strengthening exercise and toe-taping walk exercise were identified to have a partial statistical significance on the basic lower body strength (muscular strength, power, and balance) and walking (length of gait line, plantar pressure, and COP) of women in their 20s. Therefore, the study confirmed the effects of ankle-strengthening exercises and toe-taping walk exercise on the lower body exercise function, and it is considered that further studies should be conducted on more various effects of the exercises by subdividing them into different pain locations and orthomechanic findings.

The purpose of this study was to assess the antioxidant activity of vegetable extracts (pumpkin, aloe, and artichoke) containing Protaetia brevitarsis (PB) and the clinical and pathological changes in ICR mice after a single oral administration. The total polyphenol (TP) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging ability, total radical trapping antioxidant potential (TRAP), oxygen radical absorbance activity (ORAC), and single cell gel electrophoresis assay were done to measure their antioxidant activities. The effect of vegetable extracts containing PB in TP and the ORAC value was significantly higher than those without PB. In addition, all extracts had effective $DPPH{\cdot}$ scavenging and $ABTS{\cdot}+$ scavenging activities. The protective effect of vegetable extracts with/without PB on $H_2O_2$-induced DNA damage was found. In a single-dose toxicity study, mortality, body weight, physiological signs, and biochemical analysis were analyzed. Seventy mice were randomly assigned to 7 experimental groups and were administered three vegetable extracts with and without PB (2 g/kg). A full 14 days after administration, no mice mortality was observed in any group. Body weight, physiological signs, and biochemical analysis were never significantly different from those of the control group. Taken together, these findings indicate that vegetable extracts containing PB with antioxidant activities and safety could be applied as medicinal and edible resources in an industrial area.

In an architectural construction, underground construction is a critical path forming a major part of the total construction period and cost, and particularly in big cities, its size has been increasing every year. A basement wall currently constructed in the field needs a large functional work force, and the construction is under progress by the Euroform and Soldier system, which is disadvantageous in terms of the construction period. Therefore, in this research, non-supporting forms which are applicable to the buildings construction were developed, based on the non-supporting forms partly used in some civil engineering works. In addition, the size of a form was assumed and its economical efficiency was compared to that of the Euroform and Soldier system which is used most in construction fields, and the results were analyzed. The study results showed that the construction cost of composite non-supporting forms was higher than that of the Euroform and Soldier system by about 8%, and the construction cost of non-composite non-supporting forms were lower than that of the Euroform and Soldier system by about 9%. However, in the case of composite non-supporting forms, the amount of concrete and reinforcing rods remarkably decreased in structural construction, so it has the effect of an economical cost reduction compared to the construction cost of existing walls by about 35%

This study was carried out to evaluate the effect of fermentation by Lactobacillus acidophilus on the antioxidant activity of Protaetia brevitarsis larvae fed with mushroom substrates (king oyster mushroom). The total polyphenol content of the P. brevitarsis larvae extracts (PLEs) (93.33±0.98 mg GAEs/extract g) was higher than that of the fermented P. brevitarsis larvae extracts (FPLEs) (65.02±1.32 mg GAEs/extract g). The flavonoid contents of the PLEs and FPLEs were 18.3±1.57 QEs mg/extract g and 17.69±0.95 QEs mg/extract g, respectively. The DPPH radical scavenging activity showed no significant difference between the PLEs and FPLEs at a concentration of 2-4 mg/ml. However, at a concentration of 8 mg/ml or more, the DPPH radical scavenging activity of the FPLEs was higher than that of the PLEs. The reducing power of the FPLEs was also higher than that of the PLEs, and more than twice as high at a concentration of 1.6 mg/ml or more. The ORAC value of the FPLEs (79.22±0.72 μM TEs/extract g) was higher than that of the PLEs (74.34±0.37 μMTEs/extract g). A WST-1 assay of the RAW 264.7 cells indicated that the PLEs and FPLEs showed no cytotoxicity.

This study was carried out to obtain information about a several environmental factors influencing on the bionomical characteristics of Protaetia brevitarsis and Allomyrina dichotoma, which have been used for an important traditional medicinal stuffs. The moisture contents of humus affected the oviposition of P. brevitarsis and A. dichotoma, showing a suitable condition in range of $65{\sim}75%$. Very high or very low moisture condition in humus decreased the egg laying of P. brevitarsis and A. dichotoma, Also, moisture condition of humus was an important factor influencing on the egg and larval survival, egg developmental period, and feeding activity of P. brevitarsis and A. dichotoma.
