the purpose of this paper is to study on the proximate composition, mineral and saponin content in white sesame, black sesame, and perilla seed. For this purpose, we have compared six different materials: white-raw-sesame, white-roast-sesame, black-raw-sesame, black-roast-sesame, raw-perilla seed and roast perilla seed, and have come to the following results. The crude fat content was the highest in white-raw-sesame(55.3%). In all the six samples, the crude fat content in raw seeds was all higher than that in roast seeds. The crude protein content was the highest in the roast perilla seed(24.6%), and in the six samples, the crude protein content in roast seeds all higher than that in roast seeds. The total sugar content was found to be the highest in the roast perilla seed(8.29%). The reducing sugar content was higher in raw perilla seed(1.57%) than in other sample materials. The ash content was the highest in black raw-sesame(5.93%), and that percentage rates was the same as that of FAO and of Japan. Minerals like Cd. Mn. Cu. Na. Mg. Pb. and Ca. were found to be contained more in black sesame than in other sample materials. The minerals contained most in white sesame were Zn.(61.6ppm) and Fe(49.4ppm), and K was contained a little more in perilla seed than in the others. The sample materials which contain saponin most were white-roast-sesame(0.34%) and black-roast-sesame(029%).

This study was carried out to characterize the color of noodle sheet made from Korean wheat cultivars, which were then evaluated on grain and flour properties, in order to enhance the breeding-line selection for noodle wheat. In particular, a rapid method was applied to investigate the effects of iron (Fe) contents on the lightness of noodle sheet for the selection of breeding-lines with high Fe contents. Wheat flour lightness of Korean wheat cultivars had a negative correlation with ash (r = -0.634, P<0.01), protein (r = -0.635, P<0.01) and total polyphenols (r = -0.493, P<0.05). The noodle sheet color showed a positive correlation with lightness, but a negative correlation with test weight, 1000 kernels weight, PPO activity and total polyphenol contents. Also, upon the wheat flour properties, the ash, protein and total polyphenol contents had a negative correlation with the lightness of noodle sheet, and this relation varied depending on the year and cultivars. The Fe content had a negative relation with the color of wheat flour and the lightness of noodle sheet, and the potassium hexacyanoferrate(II) trihydrate (PHT) test resulted in blue color. There was no correlation between Fe contents and the color of grains with PHT treatment, but after grounding the whole grains, a negative correlation was found between Fe contents and redness (r = -0.665, P<0.001) and yellowness (r = -0.658, P<0.001) of whole wheat flour with PHT treatment. On the other hand, the lightness of wheat flour with PHT treatment showed a negative relation with Fe content.

Three types of Kochujang(soybean-red pepper paste) were prepared with glutinous rice flour (group A), glutinous rice grain (group B) or the mixture of flour and grain (group C) to investigate some chemical composition, enzyme activities and the texture during aging period. 'There were no remarkable differences in the contents of moisture, crude protein, crude fat, minerals and alcohols, titrable acidity and pH among the tested groups. Amino nitrogen content, acidic protease and saccharogenic amylase activities were measured to be higher values for group A whereas reducing sugar content higher values for group B. All tested groups contained Ca, Cu, K, Mn, Mg, P and Fe, particularly higher amount of K but a trace of Cu, Mn and Fe. All tested groups showed higher content of aspartic acid, glutamic acid, cystine, proline and lower content of histidine and valine 60 days after the preparation. The total free amino acid content was 16.49 mg/g for group A, 13.68 mg/g for group B and 15.84 mg/g for group C. The measurement of texture showed high values of hardness and adhesiveness with group A immediately after the preparation and with group B at the end of aging. Cohesiveness and springiness were high with group A while low with group B throughout aging period.

Changes in water content, dry weight, total nitrogen (T-N), P, K, Ca, Mg, B, Fe, Cu, Zn and Mn and death rate were studied in winter buds of mulberry trees. Winter buds of the early season varieties, Hongolbbong and Chongolbbong, (Morus Lhou Koioz) and midseason varieties, Kaeryangbbong and Chongilbbong, (Morus alba L.) were sampled every 7 days from February 28 to April 28, 1986. The result were as follow : 1. Water content was increased by 20% over the level of 45% in late February. The water content in Chongolbbing was the highest, whereas that in the rest of the varieties was nearly equal. 2. Dry weights of winter buds of the early varieties were always greater than those of midseason varieties. The dry weight of buds of early season varieties began to increase in late February and increased rapidly after April 18. There was no weight gain until April 12 in buds of midseason varieties, followed by a slow increase thereafter. 3. T-N and P, K, B, Fe, Cu and Zn concentration increased with time, Mn decreased, and Ca and Mg levels were constant. 4. T-N and Mn levels were higher and P, Ca, Fe and Cu lower in Hongolbbong than in the other varieties. T-N, Mg and Cu levels were lower in Chongolbbong. 5. The death rate of winter buds increased with the approach of the budding season. The rate was highest in Chongolbbong and lowest in Hongolbbong.

On the basis of the concept retained in nutition label(NL) the consumer's perception use and demand on NL nutrition knowledge(NH) purchase of nutrient controlled food and dietary modification for health were examined. The subjects were 1203 house wives mainly in the age of 30-40 and self administered questionnaire was employed. The results were as follows. Subjects' demand on nutrition information was greater while the availablity and usefulness of NL was unsatisfactory. The purchase frequencies of nutrient controlled foods were higher compared to NL reading. The use comprehenison reliability of nutrition information were better in high NK group compared to low NK group except the reliability on health claims. The required nutrients for content information were in the order of calorie Ca cholesterol Fe protein and total fat. The demand for nutrient content information was carrelated with intention of subjects' dietary modification but not the use of NL. These results indicate that NL be a good source of nutrition information and the consumers' demand for NL was based on their dietary purpose though the use of NL was unconfirmed.

This study was conducted to examine the quality characteristics of Oncorhynchus masou stock containing various amounts of tomato (2%, 4%, 6%, 8% and 10%). To accomplish this, the moisture contents, Hunter's color value, pH, salinity, sugar contents, free sugar contents, minerals and free amino acid were measured. The b value decreased, while the L value, a value, pH, salinity, sugar contents, total sugar (fructose, glucose, sucrose) and minerals (Na, Mg, K, Ca, Fe) increased as the ratio of tomato increased. A total of 33 free amino acids were detected, and the amino acid content increased as the ratio of tomato increased. Investigation of different attributes revealed that tomato content significantly affected color intensity, savory flavor and tomato taste. In the acceptance test, stock containg 8% tomato was preferred for flavor, taste, texture and overall quality ; therefore, this was taken as the optimal tomato content for maximizing the overall quality of Oncorhynchus masou stock.

Pig slurry is a good soil amendment not only because of its high organic matter content, but also because of its ability to provide various nutrients. The objective of this study was to estimate the influence of raw and processed pig slurry application on pot soil over chemical fertilizer and non-amended control soil. Change in the chemical parameters (pH, organic matter (OM), organic carbon (OC), macro and micronutrients) and microbial mass of the treated soils were monitored over 30 to 90 days. Pot soil was treated with the recommended dose of pig slurry and chemical fertilizer, and was sampled after 30, 60 and 90 days of incubation. The least significanct difference (p<0.05) was observed on Fe, Cu, Zn, available P and K between treatments. All treatments increased N, P and K content and microbial mass of soil over control soil. Interestingly, no significant effects were detected on OM, OC, total bacteria, actinomycetes and fungi mass in soil irrespective of treatments given. However fungal and bacterial counts, as well as available nutrients, were found to be higher in processed slurry (PS)-treated soil compared to other soils. In general a significant correlation existed between the fungal count and OM, OC, Zn, T Kjeldahl N (TKN), available P and K of soil. A strong negative correlation was observed between pH and Fe in soil. This study clearly demonstrated that the use of processed manure as a fertilizer could be a key for sustainable livestock agriculture.

Depositional environment off the Shihwa Dam has been studied to investigate the change of sedimentation process and the pollution. In order to understand how the sediments are distributed, polluted and modified, depositional factors have been analyzed and compared with the previous data. Study area, located off the Shihwa Dam, was surveyed to collect 25 bottom samples and 2 cores in 1996 and echo-sounding in 1997. These sediments were analyzed for the study of the global characteristics of sediment such as grain size and organic matter. Among these samples, the selected twenty surface sediments were analyzed for the comparison with their contents of metallic elements (Al, Mn, Fe, V, Cr, Co, Ni, Cu, Zn, Cd, Pb, As). According to field and lab analysis of sediments, three sedimentological zones have been generally identified around study area; near the dam (sandy Silt), near the dike (Sand) and offshore (silty Sand) zones. Textural parameters show that the content of silt and clay is dominant near the dam excepting the dike zone of LNG Storage Base and offshore (Palmido). The total concentration of Mn, Ni, Fe, Zn and Cd in bulk sediments was increased after the construction of the dam, while the content of Mn and Cr were higher near tidal channel than in the offshore area. Meanwhile, the annual increasing pattern of some heavy metal has appeared in this area. Based on this primary study, modification of the depositional environment may be caused by the construction of the dam and LNG Storage Base. Additionally, environmental evaluation on organic/inorganic factors has been suggested for interpreting environmental changes caused by coastal development in the nearshore such as the Shihwa coastal area.
