This research carried out composition analysis the subject of potteries from kiln site at Gangwon-do, Chungcheong Nam∙Buk-do and the followings are the results. Firstly, XRD analysis results showed that soft potteries were consisted of $\alpha$-quartz, feldspar and soil minerals while hard potteries were consisted of high temperature crystals like mullite, tridymite and cristobalite. Secondly, the firing temperatures of the soft potteries were determined using XRD analysis. It ranged from $550^{\circ}C$ to $870^{\circ}C$.While the firing temperatures of the hard potteries were divided into 3 groups; Group Ⅰ: Potteries with Mullite and Feldspar - ranged from $1000^{\circ}C$ to$1200^{\circ}C$. Group II : Potteries with Mullite and Tridymite - ranged from $875^{\circ}C$ to $1200^{\circ}C$. Group III : Potteries with Cristobalite - ranged above $1200^{\circ}C$.Thirdly, the result of correlation analysis using trace element such asSc, Rb of the potteries form Gangwon do and Chungcheong Nam.Bukdokilns allowed us to divide the area with their own characteristics into 4-groups. Using the same result, kilns sited at Chungcheong Nam.Buk-do were classified into 3-groups.

This research was conducted to investigate the actual condition of injured wild animals in Gangwon-do between January and December in 2002. The subject of this study was the wounded wild animals on the receipt of the governmental and the civil organizations for medical treatment. Especially, the natural monuments among the wounded were included in this research. 363 cases in birds and 274 cases in mammals were saved from injuries. In the case of the natural monuments, 140 and 7 cases got help in birds and mammals, respectively. Wild animals were injured particularly in summer and the ultimate causes were trauma and dehydration. More than 50% out of the animals under medical treatment from the organizations were dead. It was clear that most causes of the animal injuries were artificial owing to the breakdown of the ecosystem. Consequently, the consistent observation on the control system of the wild animals will be needed. And it will be also necessary to increase research works and the nationwide public city activities on the wild animals.

This study was limited Gangwon-do's manufacturing companies that participated in the educational-industrial consortium. These companies' present status and activities under implementation identified and interpreted by this study, therefore, are insufficient to be generalized into knowledge applicable to most of the companies in Gangwon-do. For more precise and detailed results, it is suggested to make further studies that cover not only those consortium companies but also non-consortium manufacturing companies in Gangwon-do. The results also suggest that it is necessary to promote some periodic manpower training programs in cooperation with local universities, to utilize professors and experts to build management strategies that can bring and secure the power of competition, and to construct a system of educational-industrial cooperation, as ways leading these companies to the 21 st century's type of business enterprise.

This study was conducted for comparison of ingredients, phytochemical compounds and antioxidant activity of Wofiporia extensa cultured in Gangwon-do, Gyeongsang-do, and Jeolla-do. Three contents of Wofiporia extensa were analyzed as oxygen (46~48%), carbon (38~39%), hydrogen (6.05~6.1%) and nitrogen (0.17~0.21%). The mineral contents of 50% ethanol Wofiporia extensa extracts were measured as sulfur (S) 145~149 ppm, Magnesium (Mg) 69~72 ppm, phosphorus (P) 122~154 ppm and calcium (Ca) 210.61~509.98 ppm. Wofiporia extensa from Gyeongsang-do (509.98 ppm) contained a significantly higher quantity of Ca than that from Gangwon-do (210.62 ppm) and Jeolla-do (223.88 ppm). In the gas chromatograph-mass spectrometry (GC-MS) analysis, oleic acid was identified in three 50% ethanol Wofiporia extensa extracts. In the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) assay for antioxidant activity, the $IC_{50}$ values of Wofiporia extensa cultured in Gangwon-do, Gyeongsang-do and Jeolla-do were calculated as 2.966 mg/mL, 23.03 mg/mL, and 4.16 mg/mL and 3.521 mg/mL, 12.17 mg/mL, and 7.40 mg/mL. In the ferric reducing antioxidant power (FRAP) assay, the $IC_{50}$ values of Wofiporia extensa cultured in Gangwon-do, Gyeongsang-do, Jeolla-do were 6.585 mg/mL, 19.06 mg/mL, and 18.97 mg/mL, respectively. In summary, Wofiporia extensa cultured in Gangwon-do had stronger antioxidant activity and higher concentration of oleic acid than that of Geyongsang-do and Jeolla-do. However, Wofiporia extensa cultured in Geyongsang-do contained a much higher concentration of Ca than that of Gangwon-do and Jeolla-do.

The objective of this study was to determine the effect of sakso 2 corn kernels and cobs extracts on antioxidant activity in rats fed a high fat-cholesterol diet (HFC) for 2 weeks. 48 male Sprague-Dawley (4-weeks-old) were randomly divided into 6 groups: normal diet (N), HFC (C), HFC and 0.05% kernel extracts of Saekso 2 (T1), HFC and 0.25% kernel extracts of Saekso 2 (T2), HFC and 0.05% cob extracts of Saekso 2 (T3), HFC and 0.25% cob extracts of Saekso 2 (T4). The weight gain in all treatment groups were significantly lower and the food efficiency ratio (FER) in all treatment groups except T3 were lower than C group. Liver index (liver weight/100 g body weight) in N group and T2 were significantly lower than C group. The level of total cholesterol in plasma of N group and T2 were significantly lower than C group and HDL-cholesterol in plasma of N group and T2 were significantly lower than C group. Malondialdehyde (MDA) concentration of thiobarbituric acid reactive substances in N group, T3 and T4 were significantly lower than C group. Activity of catalase (CAT) in all treatment groups were lower than C group. These result suggest that saekso 2 corn kernels and cobs extracts may reduce oxidative damage through the activation of antioxidative defense systems in rats fed high fat-cholesterol diets.

This study was carried out to investigate the effect of Lythrum salicaria L. ethanol extract on anti-obesity effects in rat fed a high fat diet for 8 weeks to induce obese rat model. Male SD rats were divided into normal group, control (high fat diet) group, positive control (Garcinia Cambogia extracts) group, high fat group supplemented with ethanol extracts of Lythrum salicaria L. (EELS). The body weight gain and control (high fat diet) were increased by a high fat diet, but decreased in the EELS. At the end of the experiment, the body weight in high fat diet groups was higher than that of normal diet group, while the body weights of EELS and positive control group were significantly reduced by 16.62%, as compared with that of high fat diet group (p < 0.05). The levels of serum triglyceride, total cholesterol in EELS group were significantly decreased as compared with high fat diet group (p < 0.05). The liver and mesenteric adipose tissue weights of control (high fat diet) increase than that for normal group, whereas EELS and positive control group were significantly decreased (p < 0.05). Levels of triglyceride in liver were significantly lower in EELS group than those in high fat diet group (p < 0.05). These results indicate that Lythrum salicaria L. extract may improve lipid metabolism and reduce fat accumulation and body weight.
