The contents of index components in 5 medicinal crops cultivated at different heights in Andong area. The contents of allantoin in Dioscorea batatas Decne and catalpol in Rehmannia glutinosa Liboschitz were not different by cultivation heights (100 ~ 200m). But the contents of index components in Astragalus membranaceus and Angelica acutiloba Kitagawa were higher in samples cultivated at elevated heights. At 700 m of heights, the contents of formononetin and astragaloside I in Astragalus membranaceus were 1.20 and $201.2{\mu}g/g$, respectively. The contents of decursin and nodakenin in Angelica acutiloba Kitagawa were 68.3 and 4.20 mg/g, respectively. Thus Astragalus membranaceus and Angelica acutiloba Kitagawa are recommended to be cultivated in higher altitude.

Recently, the electrical insulation design for electrical apparatuses is important to cope with the tendency of high voltage. The degradation characteristics of a superconducting coil due to an electrical breakdown should be considered to design a high voltage superconducting coil. In this paper, the degradation characteristics of 2G high temperature superconducting (HTS) wires are studied with respect to electrical breakdown tests. To analyze the dependency of the degradation characteristics of 2G HTS wires, the electrical breakdown tests are performed with AC(alternating current) and DC(direct current) voltage. All tests are performed by applying various magnitudes of AC and DC breakdown voltages. To verify the degradation characteristics of 2G HTS wires, the tests are performed with various 2G HTS wires with respect to stabilizer materials. The degradation characteristics of 2G HTS wires, such as Ic(critical current) and index number are measured by performing electrical breakdown tests. It is found that the characteristics such as Ic and index number can be degraded by an electrical breakdown. Moreover, it is concluded that the degradation characteristics of 2G HTS wires are affected by the stabilizer material and applied voltages. The cross-sectional view of 2G HTS wires is observed by using a scanning electron microscope (SEM). As results, it is found that the degradation characteristics of 2G HTS wires are concerned with hardness and electrical conductivity of stabilizer layers.

Milling qualities and indigestible carbohydrate fractions (ICF) depending on harvesting time of Goami2 (G2), mutant of Ilpum (IP) rice, was examined. Fifty days after heading (DAH) maximized head rice milling quality (57.69%) and ICF content ($5.09{\pm}0.36\;g/100\;g$). ICF contents and physical properties of G2 and IP at 50 DAH were compared. ICF of G2 was three times higher than that of IP ($1.61{\pm}0.09\;g/100\;g$). Parboiling treatment increased ICF of G2 to $7.18{\pm}0.16\;g/100\;g$. G2 showed lower water absorption index, which could lower pasting properties, but higher water solubility index, implying it contains more soluble components. Texture properties of G2 were different from those of IP, showing higher hardness, and lower adhesiveness and cohesiveness. Positive correlation was observed between ICF and hardness, but reverse correlation between ICF and cohesiveness.

As a countermeasure for reduction of corrosion in the delivery and distribution pipes used for tap water, materials for the pipelines in-houses and the effect of water quality on corrosivity of water pipelines were investigated in the distribution system of Han river. As the corrosion index at 6 water purification facilities of Han river, average Langelier Saturation Index (LI) of raw and finished water were -1.0 and -1.4 respectively and average Larson Index (LR) were 9.5 and 9.9, respectively. And also corrosion potential showed corrosivity in finished water (-431~-462 mV) as well as raw water (-426~-447 mV). This results indicate that tap water quality of han river have corrosivity. To understand the corrosivity effect in pipe material used for premise distribution system, water quality of stagnant tap water and tap water were analyzed and the differences between them were calculated. The difference concentration of iron, copper and zinc were $12.9{\mu}g/L$, $31.0{\mu}g/L$ and $45.0{\mu}g/L$ respectively in galvanized steel pipe for use more than 15 years and showed highest concentration. As a result, the control to corrosivity in the water pipelines, corrosivity control treatment in the water purification system can be applied. In advance it is necessary to monitor corrosivity of water quality using corrosive index because corrosivity may differ from the seasonal and regional characteristics and water chemicals dosage. For the future the guideline for corrosion index have to be established.

An experiment was conducted to determine the effects of different dietary crude protein (CP) levels on growth performance, nutrient utilization, small intestine protease activity and immunity index of weaner to 2 month-old New Zealand rabbits. Eighty weaner rabbits were allocated in individual cages to five treatments in which they were fed diets with CP at 14%, 16%, 18%, 20% and 22%, respectively. The growth performance and nutrient digestibility of rabbits increased firstly when dietary CP increased, then decreased. The average daily gain was the highest and feed conversion rate was the lowest when dietary CP reached 20%, namely 34.9 g/d and 2.74:1, respectively. Maximum CP digestibility was 72.1% in the 18% CP group, maximum crude fiber digestibility of 28.4% occurred in the 16% CP group and was significantly different from other treatments (p<0.01), apparent digestibility of Lys and Val followed the same trend as CP digestibility, and reached their maximum when dietary CP was 18%. Apparent digestibility of Cys, Tyr, Leu and Thr also had a similar trend to CP digestibility. Nitrogen retention (RN) increased with CP level (p>0.05), and was highest for 20% CP treatment (1.5 g/d). The effect of CP level on the rate of digestible nitrogen (DN) converted RN was small. The spleen index, thymus index, chymotrypsin and trypsin activities in small intestine were highest when dietary CP was 16%, which were 1.0, 2.8, 15.7 U/g and 125.7 U/g, respectively. There was no significant difference among treatments (p>0.05). According to the above results, the appropriate dietary CP level from weaner to 2 month-old meat rabbits was 18-20%.

Factors affecting fruit conformation of 'Fuji' apples (Malus domestica Borkh.) were investigated through correlation study of fruit weight, seed numbers, and seed weight in relation to fruit conformation indices. Apples were harvested from two orchards in 'Andong' and 'Youngyang' areas at commercial maturity and grouped by fruit weight. Average number of seeds and seed weight were 8.9 and 0.64 g in 'Andong' orchard, while 6.3 and 0.47 g in 'Youngyang' orchard, respectively. When pooled data from the both orchards were analyzed, correlation of fruit weight with seed weight was significantly positive, whereas that with seed number was not significant. Fruit shape index determined by length/diameter ratio was positively correlated with fruit weight, while relationship of the shape index with seed number or with seed weight was not significant. Asymmetry index tended to be low in apples from the 'Andong' orchard in which higher seed numbers and seed weight were observed. The asymmetry index showed highly negative correlations with seed numbers and with seed weight.

Objective : This study was conducted to investigate anti-obesity effects of mixed-Powder(Raphani Semen, Coicis Semen, Poria, Plantaginis Testa & Theae folium)(HP) & mixed water extract(Citri Pericarpium, Crataegi Fructus, Maydis Stigma, Allium Skin) (HE) in mice fed a high-fat diet. Method : 50 Female ICR mice were divided into six groups; Normal group (Ve), high-fat diet group (Po), Po+HP(0.6g/kg) group(HP), Po+HE(1g/kg) group(HE), Po+(HP+HE) group(HPE), Po+(HP+HE)*2 group(DHPE). For 8 weeks, these groups were fed their respective diets. Body weight, liver weight and weights of adipose tissues, GOT/GPT index changes & Blood Glucose index changes were measured respectively. Lipid profiles in serum were analyzed by kit of blood. Results : Groups HP, HE, HPE, DHPE had significantly reduced body weight, liver weight, adipose tissue weights and GOT/GPT index, blood glucose index compared to the Po group. Also, serum triglyceride and total cholesterol, low density lipoprotein, were significantly reduced when compared to the Po group. Group G1 had significantly increased high density lipoprotein levels. Conclusion : Mixed powder (HP) & mixed water extract (HE) show anti-obesity effects in mice fed a high-fat diet.
