Excessive nitrogen fertilization influences crop yields and quality as well as environmental pollution. In this study, yields, nitrogen use efficiency and free sugar contents of burdock (Arctium lappa L.) were evaluated at different levels of nitrogen fertilization. Nitrogen fertilizer was applied at 5 levels (0, 50, 100, 150, 200%) based on the conventional fertilization ($N=230kg\;ha^{-1}$), and phosphate and potassium fertilizer were treated by conventional P and K fertilization ($P_2O_5-K_2O=140-210kg\;ha^{-1}$) in all plots. The root yields of burdock were the highest in N 100~150% treatment plots. Nitrogen use efficiency and nitrogen recovery decreased from over N 150% treatment. Nitrogen uptake of root was greater than that of shoot in N 50~200% treatments. Fructose contents in root were inversely proportional to the level of nitrogen fertilization. As considering nitrogen recovery and root quality, economical burdock yield was obtained in N $230kg\;ha^{-1}$.

This study was conducted to investigate the effect of Chinese artichoke powder on the physicochemical properties and the sensory characteristics of yanggaeng. According to the increasing contents of Chinese artichoke powder, the $^{\circ}Brix$ value and pH levels of yanggaeng were significantly decreased whereas the moisture contents of yanggaeng was significantly increased. The result of color measurement shown that L value of groups containing Chinese artichoke powder was lower than that of control group, but a value and b value of groups containing Chinese artichoke powder were higher. Texture measurement score in terms of cohesiveness, chewiness, and brittleness for yanggaeng were significantly decreased according to the levels of added Chinese artichoke powder content. The contents of total polyphenol, DPPH radical scavenging activity, and NSA of groups containing Chinese artichoke powder were higher than those of control group. As Chinese artichoke powder increased, antioxidative activity also became bigger. Sensory evaluation scores in terms of appearance, odor, taste, texture, and overall preference of groups with 2% and 4% of Chinese artichoke powder did not show any significantly differences when compared to the control group. Based on these findings, current study suggest that addition of 4% Chinese artichoke powder was the best substitution ratio for yanggaeng.

A study was performed to assess the quality equivalence of commercially available Hwang-Ryun-Hae-Dok-Tang granules from various vendors in terms of the contents of characterizing compounds. 'Hwang-Ryun-Hae-Dok-Tang'(or 'Huanglian Jiedu Tang') is the complex medicinal herbal product which is composed of four different herbal drugs; Scutellariae Radix, Coptidis Rhizoma, Phellodendri Cortex and Gardeniae Fructus. Using a high performance liquid chromatography and direct analysis in real time mass spectrometer (DART-MS), five characterizing compounds such as baicalin, baicalein, berberine, palmatine, and geniposide were analyzed to compare the variance of the contents between the products from four different vendors. Although five characterizing compounds were all successfully detected from all the products, the contents of each compound were shown to have significant difference among vendors. For real time monitoring of characterizing compounds in medicinal herbal products, DART-MS can be successfully adopted as a powerful analytical tool.

This study was conducted to find out the effect of long-term compost application on the chemical properties of the orchard soils and apple quality. The contents of P and cations in soils were increased by the application of compost, while there are no difference in that of organic matter. The increase in application rates of compost resulted to the increase in apple yields, however, firmness and Brix of apple were as not differentiated by the compost application. The application of lower chemical fertilizer and higher compost resulted to the increase in the contents of organic matter and Ca in soils. The compost application resulted to the increase in inorganic material contents in soil but was not effective on the quality of apple fruits.

Twelve varieties of Korean rice and ten varieties of Japanese rice were selected. After being milled. they were analyzed about various physicochemical properties such as moisture, protein and amylose, a -amylase activity, gelatinization properties. And after being cooked with proper amount of water texture and other physical properties were measured by Texturometer, Tensipresser and Rheolograph-micro. Finally the sensory evaluation test was carried out. The results were as follows. 1. In case of protein contents, amylose contents and $\alpha$-amylase activity, Korean rice had a slightly higher value than Japanese As a consequence. Korean rice showed a little stronger hardness and a little weaker stickiness compared with Japanese rice. 2. Amylose contents showed very high correlation with other physicochemical properties and peak viscosity and gelatinization temperature of RVA, the ratio of stickiness to hardness( -Hl/Hl ) of Texturometer and the tan $\delta$(the ratio of dynamic loss to dynamic viscoelasticity) of Rheolograph-micro showed high correlation with other analyzed properties. 3. The ( -/+)work balance of low compression test(25% ) of Tensipresser analysis(texture analysis on the surface of cooked rice) and tan f of Rheolograph-micro showed very high correlation with sensory evaluation results. By using this parameters as major independent variables, some trials to derive high confidence multiple regression equations were accomplished. By the equations it would be possible to make an approximate pre-estimate of eating quality for unknown japonica rice.

This study was carried out to investigate physical properties of chicken emulsion sausage containing various amount of buckwheat powder. The fat content and apparent viscosity were observed gradually raised with level of buckwheat powder. The buckwheat powder contents influenced to improvement of emulsion stability. Increasing of buckwheat powder contents induced statistically decreasing of cooking loss and increasing of moisture contents of cooked sausage. However, hardness of cooked sausage was increased with level of buckwheat powder, it was due to gelatinization between protein and starch. In this study, it was suggested that addition of buckwheat powder contained higher dietary fiber changed physical properties of meat products.

This study evaluated the quality of meals served by the elementary schools in Muan based on nutrient contents and food diversity. The contents, nutrient densities and nutrient adequacy ratios(NAR) of most nutrients were higher than those calculated from the Korean RDA. However, the content, nutrient density, and NAR of iron were lower than those calculated from the RDA for 10 to 12 year old girls. The content of sodium was somewhat high. The average number of different kinds of food and dishes per meal were 19.2 and 6.0, respectively. The more the number of dishes, the higher the NARs of calcium, calories, niacin, phosphorus and protein. However, the NAR of iron showed no correlation with the number of dishes. The meals belonging to the food group intake pattern containing fruits had more vitamin C and fiber, and less protein, lipid, and phosphorus than those belonging to the food group intake pattern not containing fruits. In conclusion, the quality of nutrition of meals served by school lunch program(SLP) was considered fairly good. However, the nutritionists should consider the iron for 10 to 12 year old girls and cut down the amount of sodium. In addition, unless the children prefer the foods served by SLP or adjust to the general aspects of SLP, SLP can't accomplish its purposes. Therefore, we suggest that nutritionists should survey children's food preference and satisfaction with the general aspects of SLP.
