It was assumed that the voice of cattle is generated with the virtual white noise through the digital filter called the linear prediction filter, and filter parameters (prediction coefficients) were estimated by the maximum entropy method (MEM) , using the sound signal of the animal . The feature planes were defined by the pairs of two parameters selected appropriately from these parameters. The cattle voices were divided into three levels, that is the high, medium and low levels according to their total power equivalent to the variances of the sound signal . It was found that the straight lines could be used for recognizing tow cow and one calf for high level voices. For high and medium level voices, however, it was difficult or impossible to recognize individual cattle on the parameters planes.

Purpose Five animals sounds which are come under five sounds(Gong, Sang, jiao, zhi, yu) which are compared with the musical scale. It is looking for similarity between five animals' sounds and the musical scale. Methods 녹음 record 1 ig machine 1. Five animals (cattle, horse, pheasant, pig, sheep) sounds has been recording on tape. 2. That was transfer to CSL(computerized speech lab) 3. That was analysed to pitch, formant 1,2,3. energy pitch 4. That analysed result (Pitch, formant 1,2,3. energy ratio) of five animals are calculated and compared with the five musical scale(five sounds) Result The ratio of five animals sounds is not consistent with the musical scale in any five item (pitch, formant 1,2,3. energy). Conclusion 1.The five musical scale has no similarity with the five animals sounds 2.The five sound is supposed to oriented form theoretical back ground of five-going not have no relative with the five animals sounds

During the period of 2 years from 1993 to 1994, epidemiological investigation were carried out each time the outbreak of rabies suspected cases were informed and all specimens were transported to the Kangwon-do Veterinary Service Lab. At the Lab., autopsy and laboratory examinations were conducted as well. The results obtained as follows 1. The dogs and cattles were confirmed to be infected with rabies virus by routine histopathological findings, indirect flulrescent antibody technique, and mouth inoculation test. 2. The total numbers of rabies occured in dogs and cattles were 9, 5 heads, respectively. The regional distribution of total of 14 heads were 9 heads in Chulwon, 2 heads in Hwachun, 1 head Yangku, 2 heads in Inje and the highest number of outbreaks were orrured in Chulwon. 3. Most of dogs showed furious type and dumb type found in only one dog. 4. Cattles showed the symtoms of uneasiness feeling, excitement, disturbance howling, the change of voice, sexual accelaration, foreign body swatting and attacked to human and ani-mal and found to be died after two or four days. 5. In the seasonal outbreaks of rabies, 8 heads of the highest incidence were occured in win-ter followed by 4 heads in autumn, 1 head in spring and 1 head in summer. 6. The first outbreaks of rabies was reported in Chulwon and then transmitted into Hwachun, Yangku and Inje in turn. 7 The infectious source was supposed to be wild animals such as laccon dog, badger etc. living around the D.
