Survey on milk consumption of Daegu citizen was carried to get information for the increasing milk demand in Korea. Eighty percent of the families was found to consume milk, and 87.0 percent of the milk-drinking families stored the milk in a refrigerator. Reason of milk-drinking was appeared to be 44.0 percent for health, 39.0 percent for children's nutritional source and 14.2 percent for children's favor. The reason why the milk is not consumed was found to be 24 percent for high price of milk, 24.6 percent for yoghurt or egg consumption instead of milk and 16.2 percent for undesirable flavor of milk. The desirable milk pack was found to be 60.7 percent for cartoon pack, 29.2 percent for bottle and 10.1 percent for poly pack.

In review of he current technical difficulties and weaknesses in producing filters, this investigation presents a method to evaluate metallic fiber filters by utilizing the theory of fluid dynamics. A method for evaluations of the efficiency of filters in estabilished. Also the filter configuration is analyzed and the filter media is characterized. A trial product of pleated type filter is designd and produced. The product has optimal filtering surface area per unit flow rate. Also tests for filtration efficiency and characterizations of the products were conducted.

Recently, there have been much corncerns about the strategies which can reasonably increase farm income at the average farm level. In other words, as a result of third-term Five Year Economic Development Plan there was a remarkable gap between farm household and non-farm household incomes. Therefore, various policy tasks to eliminate this unbalanced income growth are currently being implemented. This study was carried out to identify the situation of livestock farming at general farm level, regarded as one of income generation strategies for the farm sector. Some results of the study can be summarized as follows: First of all, it was found that a group of farms which raise a small size of animals like Korean cattle, hog, and various poultry gave higher resource bases as compared with that of non-livestock farms. Secondly, it was also recognized that both farm and farm household income levels of small-scale livestock farms were higher than those of non-livestock farm group within the same region, specifically as much as approximately ₩200,000. Thirdly, it was known that the average size of animal raising per household in 0.9 head of cattle, 0.8 head of hog, and 34 lyers of poultry, respectively. To the end, according to the farm disposal practices of major by-products, only about 18 percent of total rice straws produced at individual farms was utilized for the animal raising, and about 45 percent of all the brans available at farms for the livestock enterprise. The rest of straw and brans in regarded as selling at farm level. In this respect, it may be recommended either to increase current size of animals or to expand number of livestock farms.

A new colorimetric method for determining phospholipid in serum and red blood cell membrane has been presented. The advantages of the present method over previous methods are simple and rapid treatments with reasonable accuracy. The procedure includes the following steps; extraction of total lipid from the sample with lipid extraction solvent, isolation of phospholipids from total lipid with chilled acetone and treatment of phospholipid toluene solution with copper reagent, followed by color development of copper salts of phospholipids with sodium-diethyldithiocarbamate. The recovery and reproducibility of the present method were proven to be 99.41% and 1.97%(coefficient of variability), respectively. By the present method, phospholipid concentrations in serum and red cell membrane of slaughtering cattles were determined to be 59.64㎎/dl and 178.63㎎/dl, and those of slaughtering pigs were 72,00㎎/dl and 190.27㎎/dl, respectively.

To investigate the effect of testosterone upon the body weight, feed intake, and creatinine and cholesterol content in the blood plasma, thirty rats which were three months old, were assigned into 6 groups of 5 rats. Those groups included one control group and 5 castrated groups which injected 0 to 4 mg of testosterone each. The body weight gain in the control showed relatively higher value than the castrated, showing no significant effect between the groups. Also no significant effect in the feed intake between the groups, due to the amount of testosterone injection, was found. The creatinine content in the plasma showed a highly significant effect between the groups, giving a lower concentration in the castrated group compared with the control while the content in the hormone treated groups inceased with increasing amount of testosterone injection. Otherwise the cholesterol concentration in the plasma was inversely proportional to the creatinine in each group.
