Self-weight consolidation test and soil property of dredged soil at Incheon habour route were analyzed to determine the initial dredging reclamation amount, reclamation depth, and estimating the required time of self-weight consolidation with calculation of the final planned height of dredging reclamation site. The moisture content, void ratio and ratio of volume change with elapsed time after throwing were estimated through Yano's empirical equation. As a result, there was a less variation in elements when fine-grained soil content was low as similarly to the behavior of coefficient of sedimentation-consolidation, Cs and the highest variation was shown at the fine-grained soil content of 50%. The retention ratio according to the fine grained soil content that could reinforce the comprehensive aspect of retention ratio for each particle size presented in the standard of estimate for reclamation construction work was calculated and presented using the calculated ratio of volume change.

The purpose of this study is to analyse the effects of obesity management program in food attitude and food habit, body composition(body fat ratio, body fat weight, lean body mass, total body water), abdominal girth(waist, hip, thigh), and serum lipid level(cholesterol, low density lipoprotein, triglyceride, phospholipid, NE fatty acid, high density lipoprotein) of middle aged women. Data for the study were collected from July 4 to August 25, 2000. The study objects were 20 middle aged women(10 controls and 10 experimental objects) from 40 to 50 years old who had body fat ratio more than $30\%$ and waist girth more than 80cm. The results were as follows: 1. Similarity test between experimental group and control group processed by serum HDL level showed the significant difference(t=3.25, p=0.004), but that processed by age, body weight, body fat ratio, body fat weight, lean body mass, total body water, waist girth, hip girth, thigh girth, cholesterol level, LDL level, triglyceride level, NE fatty acid level, food attitude and food habit score showed no significant difference(p>0.05). These findings imply that the two groups are similar in the sample distribution. 2. The effects of the abdominal obesity management program The obtained results indicate that the abdominal obesity management program in middle aged women changes the food attitude & the food habit. decreases the body fat ratio & the body fat weight and increases the lean body mass, and decreases the girth of waist & hip and the serum level of cholesterol & LDL. Therefore, it is concluded that the abdominal obesity management program can be applied for nursing intervention to decrease the body fat weight and abdominal obesity.

Regarding the fattening of younger cattle that the Ministry of Agriculture Forestry and Fisheries (MAFF) recommends in Japan, this study looked at vitamin A control in feed and blood and its effect on performance of production and carcass composition of Wagyu steers. Five sets from 10 Wagyu artificial identical twins were divided to into 2 groups, a restricted group (Test) and a supplied group (Control). The body weight at the finishing time of the Test was significantly lower than that of the Control (p<0.05). The daily gain from 13 to 21 months old, as the animals in the Test were fed the concentrated feed without Vitamin A, was significantly different (p<0.05) between the Test and the Control. The total daily gains for the Test and the Control for the fattening period were 0.82 kg/day and 0.93 kg/day, respectively, which showed a significant difference (p<0.01). Regarding the rib thickness, the Test was thinner than the Control. The Beef Marbling Scores of the Test and Control were 3.60 and 2.80, respectively. The muscle weight of the Test was significantly smaller than that of the Control (p<0.01). However, regarding the ratio to the carcass, the Test was significantly higher than the Control (p<0.05). For the fat weight, the Test was smaller by about 15 kg than the Control (p<0.01). Furthermore, for the fat ratio to the carcass, the Test was significantly lower than the Control (p<0.05). The bone weights of the two groups were approximately the same. Regarding the ratio of bone to carcass, the Test was higher than the Control (p<0.01). For the younger fattening method, the low level vitamin A in the serum had the effect that the muscle ratio to the carcass weight was greater and the fat was less, but the carcass and muscle weight were less.

This research aims to find a way to utilize the literature to select the herbs to be added or subtracted according to the condition of the patient after determining the basic prescription to be used for the patient. The study is based on data concerning the herbal composition and application of prescriptions described in the Donguibogam. The composition herbs was expressed as a weight ratio, the standard deviation of the weight ratio was calculated for each prescription, and the case where the weight ratio was greater than the base value (highest weight ratio - standard deviation) was designated as a principal herb. The various expressions of applications were changed to representative terms by the researcher and used to calculate the frequency. Of the 4,373 prescriptions for Donguibogam, 3,307 were able to be expressed in terms of weight ratios with 640 prescriptions using Rehmannia glutinosa, Cnidium officinale, Angelica gigas and Paeonia lactiflora as the principle herb. Of the 640 prescriptions, 508 prescriptions included applied information. Rehmannia glutinosa can also be used for symptoms such as fetal leakage(胎漏), short ingestion(食少), fever(發熱), dazed expression(眼花). Cnidium officinale can also be used for symptoms such as migraine(偏頭痛), stroke(中風癱瘓), tetanus(破傷風). Angelica gigas can also be used for symptoms such as forgetfulness(健忘), incontinence of urination(小便不通), palpitations(驚悸). Paeonia lactiflora can also be used for symptoms such as heart pain and abdominal pain(心腹痛), cough(咳嗽).

The purpose of this experiment was to determine the influence of providing laying hens with extra feed on egg production and egg quality parameters. A total of 480 laying hens (38-weeks old), were divided into five treatment groups (eight replicate cages/treatment and 12 layer/replicate) according to their starting body weight (1.98 ± 0.05 kg) in this four-week feeding trial. Five different feed allowances of the same diet (105, 110, 115, 120, and 125 g·day^-1·bird^-1) were assigned to layers. Daily inspections of remaining feed (around 0.1g) and layer mortality (0%) showed no harmful impact of supplying extra feed to layers. Providing 120 and 125 g of feed per day to layers resulted in the highest final body weight, large-egg ratio, and improved yolk color among all treatment groups. Layers receiving 125 g of feed daily had the highest egg weight, but the highest egg production ratio was observed in layers receiving 110 g of feed/day. The additional supply of feed did not have a negative impact on the productive performance or egg quality of the layers. The provision of 125 g feed per day led to an improvement of large-egg ratio, egg weight, and yolk color, but likely led to obesity of the layers, which manifested as an increase in body weight and a decline in the egg production ratio. We concluded that 110 grams of feed was the proper quantity after taking into consideration the significance of the health of the laying hen to the overall production performance.

The ratio of aniline dimer (p-aminodiphenylamine), which is a nucleation site of chain growth in a chemical polymerization of aniline monomer, to aniline monomer was controlled to synthesize polyaniline with the molecular weight ($M_w$) between 10000 and 20000 g/mol. The result of OCP measurement showed that the reaction rate of polymerization was increased as the mole ratio of dimer was increased. The increase in the molar ratio of dimer resulted in the shift of absorption wavelength of polyaniline to the short wavelength region on measurement of UV/Vis and the decrease of molecular weight on the measurement of GPC.

In order to select the suitable soybean cultivars for paddly field cultivation, growth response and yields characters were investigated with 37 Korean domestic soybean cultivars, in Yeoncheon, Gyeonggi province. The results can be summarized as follows ; When the soybeans were cultivated in paddy field, significant differences were observed in growth responses at each growth stage and yields among the cultivars. Yields of six cultivars, such as Danbaekkong, Paldokong, Pungsannanulkong, Myeongjunamulkong, Saeolkong, and Namhaekong, were less than 200kg/10a, however, seven cultivars, such as Shinpaldalkong 2, Sohokong, Dormikong, keumkangkong, Bukangkong, Dajangkong, and Geomjeongkong 2, showed highest yields ranged from 301~385kg/10a. At V5 stage, highly positive correlation(r=091$^{{\ast}{\ast}}$) was observed between the top dry weight and leaf area while negative correlation was existed between T/R ratio and root dry weight. However, at R2 age, leaf area was correlated with both top and root dry weight while T/R ratio was correlated with leaf area and top dry weight. Thirty-seven soybean cultivars used in this experiments were classified into 3 different clusters based on 19 important agronomic characters, and genotypic properties of the cultivars were similar in each cluster. In results, high yields could be achieved by selected cultivation of suitable soybean cultivars such as Shinpaldalkong 2 which showed early maturation date and highly ripening ratio.

It is well known that many kinds of chemical or metalic agent which were ionized or undissociated at toxified external medium and remarkable effect occurred to the fresh water fish. The effects of hydrogen ion concentration on serum protein of fresh water fish, (phycephalus argus CANTOR) had not been reported yet. In this point, authors attempted to study the changes of A/G ratio, total protein, hemoglobin, hematocrit, RBC , liver and kidney weight of snake head in the above environment. 95 snake heads were subjected to external medium with PH-4.5 and A/G ratio, hematocrit, hemoglobin, total protein, RBC, and liver & kidney weight were measured at 32.80, 15202000 and 272 hours respectively. In whole experimental period, L 1 and L2 globulin increased, on the other, albumin decreased as compare with control . Hence, the A/G ratio decreased remarkably . Though, total protein increased prominently through the whole experimental period, hematocrit, hemoglobin, RBC, increased only at 80 hours, and then decreased as compared to the control. Liver weight revealed distinctive increase at 80 hours, but no remarkable change could be seen there after. Hence, kidney weight revealed continuous rise. By these results, it may be said that as snake head were subjected to external medium with PH-4.5, this environmental factor influenced protein metabolism , blood component and organs.
