Individual management of the animal is the first step towards reaching the goal of precision livestock farming that aids animal welfare. Accurate recognition of each individual animal is important for precise management. Electronic identification of cattle, usually referred to as RFID (Radio Frequency Identification), has many advantages for farm management. In practice, however, RFID implementations can cause several problems. Reading speed and distance must be optimized for specific applications. Image processing is more effective than RFID for the development of precision farming system in livestock. Therefore, the aim of this paper is to attempt the identification of cattle by using image processing. The majority of the research on the identification of cattle by using image processing has been for the black-and-white patterns of the Holstein. But, native Japanese and Korean cattle do not have a consistent pattern on the body, so that identification by pattern is impossible. This research aims to identify to Japanese black cattle, which does not have a black-white pattern on the body, by using image processing and a neural network algorithm. 12 Japanese black cattle were tested. Values of input parameter were calculated by using the face image values of 12 cows. The face was identified by the associate neural memory algorithm, and the algorithm was verified by the transformed face image, for example, of brightness, distortion, noise and angle. As a result, there was difference due to a transformation ratio of the brightness, distortion, noise, and angle. The algorithm could identify 100% in the range from -30 to +30 degrees of brightness, -20 to +40 degrees of distortion, 0 to 60% of noise and -20 to +30 degree of angle transformed images.
This paper presents a study on the discharge capacity of geotextiles as a horizontal drain layer placed between the layers of earth fill and natural soft ground. Required discharge capacity of geotextiles as drain layers estimated by consolidation analysis is proportional to the consolidation coefficient of the ground soils and the width of the earth fills.The field discharge capacity of the geotextiles are measured by the hydraulic transmissivity test. And the results show wide variation according to the material characteristics of geotextiles, water content of the soils, vertical pressure, and etc. For the short horizontal drain length, geotextile filter mat can be used for the horizontal drain layer. And for the long drain(25∼55m), it is used for the drain together with Bord Drain.
New balloon flower (Platycodon grandiflorum) variety, Jangbaek, had been developed by pureline selection from some native cultivars collected in Milyang by the medicinal crops research team of the National Yeongnam Agricultural Experiment Station at 2002. Major agronomic characters of this variety is white flower, large primary root and higher total amount of crude extract in root than that of check cultivar. Fresh and dry root yield of Jangbaek are 16.63 ton, 3.836 ton per hectare, respectively, 14 percent higher than that of check cultivar in regional adaptation trial. This new variety, Jangbaek adaptable to most of cultivating area in Korea.
The purpose of this study was investigated the effect of training and antioxidant compounded administration for 6 weeks on blood glucose, lipid peroxidation, vitamin E, selenium concentration by 30minute edurance exercise in STZ induced diabetic rats. It was respectively random assigned to 12, divided into three group(training, antioxidant compounded administration and exercise, antioxidant compounded administration group respcectively). Endurance exercise test(16-17m/min) was performed at six weeks exercise method(30min, 5day/week) similarly. The follow results was obtained which was measured by experimental. Each exercise test periods, blood glucose concentration decreased any significant in post-exercise than rest. Each exercised test periods, TBARS showed any significant differences among groups. especially TBARS decreased in training group and antioxidant compounded administration training group. Each exercise test periods, vitamin E concentration in liver showed any significant differences among three groups. especially antioxidant compounded administration training group and antioxidant compounded administration group decreased in post-exercise. Each exercise test periods, selenium concentration in liver showed any significant differences among three groups. especially selenium concentration of all groups decreased in post-exercise. These results indicate that training and vitamin E, selenium compounded administration function lead to antioxidant system acceleration and inhibition of lipid peroxidation. Also, thesis suggests the possibility that transient exercise inhibit the effect of lipid peroxidation adapted in long periods training and antioxidant compound administration.
