Abstract
The purpose of this study was to investigate the effect of jujube on the physicochemical properties of Injeulmi during storage. Various Injeulmi samples were prepared with steamed glutinous rice, glutinous rice flour, or brawn glutinous rice flour along with the addition of chopped jujube at 3, 6, 9, or 12% of rice. In sensory evaluation, the more jujube was added, the stronger sweetness and bitterness were obtained. The samples made with steamed glutinous rice gave the harshest texture. Tenderness and moistness of Deachu-Injeulmi were the highest in the samples made with glutinous rice followed by brown glutinous rice flour, and glutinous rice flour, and they were increased with less amount of jujube. The chewiness of the samples made with brown glutinous rice flour was the highest and the samples made with glutinous rice were the coarsest. The more jujube was added, the redness and yellowness of Daechu-Injeulmi were increased. The moisture content was higher in the samples made with glutinous rice followed by glutinous rice flour and brown glutinous rice flour. The reducing sugar content of samples during storage was higher in the order of glutinous rice, glutinous rice flour, and brown glutinous rice flour, and it was dramatically reduced until 48 hr of storag e ; however, it was increased a little bit after 72 hr. The degree of gelatinization was reduced rapidly during the first 24 hr of storage, and it was decreased in the order of brown glutinous rice flour, glutinous rice flour, and glutinous rice. The springiness and cohesiveness were decreased during storage. The chewiness and gumminess were increased with the increase of added jujube, and they were increased until 24 hr of storage, then decreased after 48 hr. The hardness was the highest in the samples made with glutinous rice and 12% of chopped jujube showed the least change in the hardness. The more jujube was added, the less change in the hardness of samples was observed during storage, consequently retarded the speed of retrogradation.

Abstract
This study was to investigate the behavior related to health, food habits, food consumption pattern and nutrient intakes of female students who residing in dormitory(self cooking) according to BMI(Body Mass Index). This study was carried out by questionnaired on June, 2000. Three hundred nine students were answered. The results were as follows: The means of height, weight and BMI were 162.37±4.36㎝, 52.48±5.54㎏ and 19.89±1.89. Under 20 of BMI among students were 53.1% and 20-25 of BMl were 46.9% of students. In the self recognition of body shape, 63.4% of under weight subjects answered that their weight were normal. 73.1% of normal weight regard themselves more obese than their actual body shape normally shows. 51.2% of under weight subjects had attempted to control their weight. This resu1ts suggest that their weight control attempts were unnecessary. 81.4% of subjects were answered irregular meals regardless BMI. 89.6% of subject skipped breakfast. The main reasons were due to lack of time or not to eat proper food. Under weight subjects had less snack than normal weight subjects did(p＜0.05). Normal weight subjects had more bun and cake than under weight subjects(p<0.05). The consumption of vegetables and fruits were low regardless BMI. Mean energy, protein, Fe, Vit A. B_1, B_2, niacin, Vit C were above 75% of RDA, except calcium, in subjects. This study suggest that a comprehensive nutrition education program is need for college student in dormitory to impove their eating habits about skipping meal and breakfast and to increase the consumption of vegetables and fruits.

Abstract
The effects of α-chymotrypsin and trypsin treatments on the functional properties (degree of hydrolysis, solubility, and emulsifying capacity) of the soy protein isolate prepared from Jinpum soybean milk(JS milk) which has been developed as low lipoxidase-active soybean variety in Korea and extracted from commercially defatted soybean meal milk(DSM milk). The mixing ratios of JS milk to DSM milk were adjusted to 10:0, 7:3, and 5:5, respectively. The general quality attributes(yield, pH, titrable acidity, moisture contents, crude protein contents, color, textural properties, and sensory characteristics) of soybean cheese which has been prepared with the resulting soy protein hydrolysates were evaluated. Jinpum SPI was better subjected to trypsin than α-chymotrypsin hydrolyses as indicated by better solubility and emulsifying capacity of the hydrolysates. The degree of hydrolysis and solubility of Jinpum SPI were higher than the soybean isolates from DSM milk. The increased ratios of DSM milk in the mixture resulted in the reduced yields and crude protein content along with the lowered titratable acidity while the pH values and moisture contents showed the opposite trends. In color characteristics, the increased amount of DSM milk brought about the significantly lower Hunter color reflectance values of lightness of the cheese products, along with the higher redness and total color difference value(ΔE). However, the enzyme treatment alone was not enough to cause any color differences. The increased ratios of DSM milk also caused the significantly lowered textural parameters such as hardness, adhesiveness and cohesiveness of the soybean cheese. Between the enzyme treatments, the α-chymotrypsin treated samples resulted in the higher hardness and cohesiveness values of the products than those from the trypsin-treated ones. In organoleptic properties of the product, the better mouthfeel and overall quality scores were obtained from the trypsin treatments as compared with those from the α-chymotrypsin ones. The mixing ratios of 10:0 and 7:3 were more favored than that of 5:5 as far as mouth-feel, yellowness and overall quality of the products were concerned. On the overall, the mixing ratio of 7:3(JS milk : DSM milk) and the trypsin treatment of the mixture was recommended for better manufacturing of high-quality soybean cheese.
