본 연구에서는 녹용의 상품성 향상을 위한 건조 및 포장방법의 개발, 녹용의 유통체계 확립 및 녹용 수요의 다변화에 대처하기 위한 기초연구로 엘크녹용의 물성 특성을 규명하였으며 그 결과는 다음과 같다. 1. 압축응력은 생녹용 중심부의 경우 상대 $60.73\;g/mm^2$, 중대 $145.65\;g/mm^2$, 하대 $260.97\;g/mm^2$, 벨벳층은 상대 $70.67\;g/mm^2$, 중대 $811.90\;g/mm^2$, 하대 $3,235.52\;g/mm^2$ 건녹용 중심부의 경우 상대 $190.43\;g/mm^2$, 중대 $445.81\;g/mm^2$, 하대 $705.86\;g/mm^2$, 벨벳층은 상대 $734.01\;g/mm^2$, 중대 $1,238.40\;g/mm^2$, 하대$ 4,134.03\;g/mm^2$ 였다. 2. 전단응력은 생녹용의 경우 상대 $50.24\;g/mm^2$, 중대 $294.44\;g/mm^2$, 하대 $423.47\;g/mm^2$, 건녹용은 상대 $124.14\;g/mm^2$, 중대 $367.69\;g/mm^2$, 하대 $425.86\;g/mm^2$ 였다. 3. 인장응력은 생녹용의 경우 상대 $13.59\;g/mm^2$, 중대 $62.85\;g/mm^2$, 하대 $112.07\;g/mm^2$, 건녹용은 상대 $77.24\;g/mm^2$, 중대 $175.87\;g/mm^2$, 하대 $184.06\;g/mm^2$ 였다. 4. 녹용을 건조할 경우 수분증발과 수축, 표면경화 등의 조직 변화에 의해 물리적 성질이 변화하며 중심부는 상대에서 하대로 갈수록, 벨벳층부는 하대에서 상대로 갈수록 물리적 변화가 크게 나타났다. 5. 엘크(Elk(Cervus canadensis))녹용은 생물체의 뿔이라는 특성상 생장점의 위치에 따른 응력의 크기변화가 크게 나타났다. In this study, physical properties of Elk antler was investigated to develop the optimum drying and packaging methods for improving the antler quality as well as deal with diversify of demand. After the antler was sliced with 5 mm thickness, and the compressive, shear, and tensile stresses were measured at the center and velvet parts of pre-dried and dried antlers after the contained water rate of the dried antlers was maintained below 10%. The results are as follows. 1. Considering the center of pre-dried antlers, the compressive stresses were $60.73\;g/mm^2$, $145.65\;g/mm^2$, and $260.97\;g/mm^2$, respectively at the upper, middle, and lower parts while $70.67\;g/mm^2$, $811.90\;g/mm^2$, $3,235.52\;g/mm^2$, respectively for velvet layer. Considering the center of dried antlers, the compressive stresses were $190.43\;g/mm^2$, $445.81\;g/mm^2$, and $705.86\;g/mm^2$, respectively at the upper, middle, and lower parts while $734.01\;g/mm^2$, $1,238.40\;g/mm^2$, $4,134.03\;g/mm^2$, respectively for velvet layer. 2. For the pre-dried, the shear stresses were $50.24\;g/mm^2$, $294.44\;g/mm^2$, and $423.47\;g/mm^2$, respectively, and $124.14\;g/mm^2$, $367.69\;g/mm^2$, and $425.86\;g/mm^2$, respectively for the dried antlers. 3. The tensile stresses were $13.59\;g/mm^2$, $62.85\;g/mm^2$, and $112.07\;g/mm^2$, respectively for the pre-dried and $77.24\;g/mm^2$, $175.87\;g/mm^2$, and $184.06\;g/mm^2$, respectively for the dried antlers. 4. In the case of drying antlers, the physical characteristics of the antlers was. changed such as moisture evaporation, contraction, and surface hardening. For the center part, the changes of the physical characteristics were more significant at the lower part while at the upper part for the velvet layer. 5. The stress changes of Elk antlers was shown very remarkably according to growth point. Moreover, the stress was clearly higher at velvet layer part to the center part, base parts compared to the upper parts.

A study was conducted to develop a management policy of animal waste in Northern Chungbuk province through investigating the status of animal waste management. In management of swine manure, rotary composting including a simple piling method has a portion of $64\%$ using as a liquefied fertilizer $18\%$, purification $9\%$ and ocean dumping $9\%$ respectively. Most of them use the animal waste as a fertilizer to the agricultural land. The exercise ground of dairy farms was bedded with $70\%$ of sawdust and $30\%$ of conventional soil ground besides the stall. They had a storage tank for the waste water from milking parlor. Korean beef cattle farms mostly run sawdust stall, which changed new one in a term of 6$\~$12 months. In case of layer, manure management was conducted in the order of simple piling method, rotary composting and ventilation into the piling mostly. Comparing the amount of excreted animal manure with that of possible spreading, the latter can be spread more than 2.9 times than the former in Northern Chungbuk province. The Northern Chungbuk province is an appropriate place to carry out an environmentally friendly animal production. An utilization model as a liquefied fertilizer should be developed for paddy field, upland field, orchard, and forage field to in-crease the value of animal waste effectively.
