The objective of this study was to prove the effect of pig slurry application with charcoal on nitrogen use efficiency (NUE), feed value and ammonia (NH₃) emission from maize forage. The four treatments were applied: 1) non-pig slurry (only water as a control), 2) only pig slurry application (PS), 3) pig slurry application with large particle charcoal (LC), 4) pig slurry application with small particle charcoal (SC). The pig slurry was applied at a rate of 150 kg N ha^-1, and the charcoal was applied at a rate of 300 kg ha-1 regardless of the size. To determine the feed value of maize, crude protein, dry matter intake, digestible dry matter, total digestible nutrient, and relative feed value were investigated. All feed value was increased by charcoal treatment compared to water and PS treatment. Also, the NUE for plant N was significantly higher in charcoal treatments (LC and SC) compared to PS treatment. On the other hand, there is no significant difference for feed value and NUE between LC and SC. The NH₃ emission was significantly reduced 15.2% and 27.9% by LC and SC, respectively, compared to PS. Especially, SC significantly decreased NH₃ emission by 15% compared to LC. The present study clearly showed that charcoal application exhibited positive potential in nitrogen use efficiency, feed value and reducing N losses through NH₃ emission.

Alkaline hydrolysis to improve the hand of PET/acetate union fabric was studied in relation to skin saponification and retarding effect of salts on the alkaline hydrolysis of cellulose acetate fiber, accelerating effect of salts on the alkaline hydrolysis of PET fiber, and changes of total hand value(T.H.V) of PET/acetate union fabric treated with alkali/salt solution. It was found that the rate of saponification of acetate was delayed by the addition of salts such as LiCl, NaCl and CH$_{3}$COONa into NaOH solution below 10 minutes. The rate of shrinkage of acetate fabric treated with 5g/l NaOH solution at 9$0^{\circ}C$ and 60 minutes showed 20 % but it was decreased 8% by. the addition of 120g/l Concentration of inorganic salts. We could know that the rate of alkaline hydrolysis of filament yarn treated with alkali solution at 9$0^{\circ}C$ and 60 minutes was delayed about 3 % using 2,000T/M of hard twist yarn, especially acetate filament treated with alkali solution at 9$0^{\circ}C$ and 10 minutes was delayed about 10%. T.H.V. of PET/acetate union fabric was increased from 2.77 to 3.04~3.18 by the addition of salts into alkali solution.

A total of 331 dairy cattle in Jeonnam area were examined for the breeding status and hematological values during the period from June to August. 1971 and 1974. The data obtained were analysed according to the status of breeding and the type of farm management. The results obtained in this work were summarized as follows: 1. 331 dairy cows were grouped as pregnant (63.81%) anestrus after parturition (12.45%), pregnancy unknown (11.48%), repeat breeder (10.32%), and others (1.94%). 2. The summery of reproductive histories and clinical examination were as follows. Average of calving interval was 16.5 months, interval from parturition to first breeding 97 days and postpartum interval to first estrus 72 days. Services per conception was 1.6 rate of postpartum estrus (60 days) 12.0%, and the rate of repent breeder 10.3%. 3. Generally, the blood values of RBC, Hb, serum total protein and A/G ratio were lower than those normal values, especially, the cows which showed abnormal values belonged to the repeat breeder and the unknown to conception group. The mean value for serum inorganic phosphorus was the normal value or hyperphosphatemia, on the other hand, the mean value for serum calcium of the repeat breeder group was the lowest than the other group. 4. Follow-up evaluations on the results of the laboratory tests strongly suggest that the problems of repeat breeder had a tendency to occur more frequently in the large herd (A and B type farm), and the Ca/P ratio of almost all the cows showed abnormal values.

The purpose of this study was to evaluate the quality characteristics of chicken sausage prepared with turmeric (Curcuma longa L.) powder (T) during storage at $4^{\circ}C$ for 20 days. The pH and color values (a and b values) of sausage containing turmeric powder were significantly higher (P<0.05) than the control for both uncooked and cooked sausage. The hardness, chewiness, and gumminess of control sausage significantly changed after 15 days of storage, while the hardness and gumminess of turmeric-supplemented sausages (T) significantly increased after 5 days (until 15 days) for cooked sausages. The total phenolic content and DPPH radical scavenging activity of turmeric-supplemented sausages was significantly higher (P<0.01) than the control for both uncooked and cooked sausage during storage. On the other hand, the acid value of the control was higher than the turmeric-supplemented sausages and the peroxide value of the control was significantly higher (P<0.05) than the turmeric-supplemented sausages after 15 days of storage. Microorganism analysis revealed that total plate counts of uncooked and cooked control sausages were significantly higher (P<0.05) than turmeric-supplemented sausages at 20 days of storage. As a result, sausages prepared with turmeric powder demonstrate antioxidative activity and lipid oxidative stability during storage.

This study explored an impact of consumer innovativeness on fashion consumption propensity and clothing satisfaction, focusing on female consumers in 20's and 30's. Specifically, the smart phone users had been the subjects of study because they accept new things earlier than others. The collection of data was carried out for one month in September 2011, and a total of 390 copies were used for final analysis. A statistical package SPSS 16.0 was used for analysis of data. First, the impact of innovativeness on fashion consumption propensity was explored. It was found that the innovativeness has impact on ostentation-seeking propensity and personality-seeking propensity. The impact of innovativeness on the clothing satisfaction was explored. It was found that the innovativeness has negative impacts on tangible value satisfaction and intangible value satisfaction. Second, it was found that if an innovative consumer has less ostentation-seeking propensity and less personality-seeking propensity, the innovative consumer gets more satisfaction from tangible value of clothes. On the other hand, if an innovative consumer has less ostentation-seeking propensity, the innovative consumer gets more satisfaction from intangible value of clothes. Third, the differences in consumer innovativeness, fashion consumption propensity and satisfaction dependent on the age of consumers were explored. In innovativeness and fashion consumption propensity, fashion-seeking propensity and personality-seeking propensity had significant differences between different age groups. In satisfaction, tangible value satisfaction had significant difference between different age groups. However, there was no significant differences between different age groups in ostentation-seeking propensity, economy-seeking propensity and intangible value satisfaction.

According to the dietary surveys and national food balance sheets, the dietary state of person living in Korea is ingesting a high level of grain and vegetable diet and very low animal sources. The daily calory intake is about 2,300-2,600 Cal. per head in which a total protein intake is 69-86 gm respectively. These data indicate no shortage of calory and total protein intake. However, the intake of animal protein is only 4-11 gm and the fat is 8-18 gm, both of which are far below the requirment. The low fat intake brings about a low level of fat soluble vitamins, and that V-A intake is as short as the half amount of the allowance. Riboflavine is also about a half of dietary requirment. Both thiamin and ascorbic acid intake are sufficient. The calcium intake is 0.26-0.5 gm per day which is inadequate. In fact, biochemical findings through field survey show; serum protein 6.7 gm, hemoglobin 13.1 gm and hematocrite 41.5% all of which are lower than the Kwon's report. The serum V-A and uunrinary riboflavin value are also lower than the Williams'es report. Clinically, inflamation of the eyes, cheilosis, pathological signs of tangue, xerosis of the hand and arm, or the like are frequently seen. On the other hand, there is no suitable diet available for the weaning infant and delayed weaning is a common practice. A school lunch program is still in an early stage of development. Another example can be cited that the Korean infant grows faster than the Japanese until one year of age, and no difference is noted between the Korean and the American infants up to six monthes of age, thereafter the former lags in the growth rate. This might be mainly due to the nutritional reasons as mentioned above, and in part due to the high inidence of intestinal parasitism and others.

By applying super-high pressure (150-250 MPa) to a sealed pressure vessel, it is possible to make oyster shucking machine that automatically opens two-sheet shellfish or oysters. Possibility of developing a shucking machine was confirmed by identifying the working pressure for meat of oysters produced in the southern coast and conducting sensory evaluation of meat oysters. As a result of confirming the shucked oysters under super-high pressure of 150 MPa in the pressure vessel, the number of type A with separated shells and well-separated meat was 22 and type B with both shells and internal meat and shells not separated. For the oysters that were treated at 175 MPa, there were 58 type As with shell separated and meat well separated and 42 type Bs without oyster shells and insides. When looking at the oysters shucked at 200 MPa in the pressure vessel, the number of type A was 86 and type B was 14 accounting for 86% of oysters with good marketability. As a result of shucking oysters by applying 250 MPa, 96% type A oysters and 4% type B oysters were obtained from the total specimen. The total specimen oyster weight used in the conducted experiment was 6 kg, the average oyster shell weight was 3.99 kg and the average oyster meat weight was 1.25 kg. Therefore, the fatness of oyster meat, which measures the added value of oysters, is 20.8%. Sensory evaluation was conducted on thinned oysters by hand and type A oysters shelled by machine with an operating pressure of 200 MPa. The hand-worked oyster sample scored 4.7 points only in salty taste, and scored 5.0 or higher in color, shape, smell, fishy taste, texture and preference.
