This study questionnaires 166 inpatients and outpatients with stroke in 8 hospitals, including Wonkwang University Gwangju Korean Hospital from July 2 to 31, 2001 in order to find out the influence of general nature, smoking, drinking, obesity, and perception of saltness of patients with stork on the outbreak of stroke and to examine important factors by dividing into hemorrhagic and ischemic stroke. Finally, collected data is analyzed statistically, using SPSS 7.5 statistics package. This study reaches a conclusion as follows. 1. For general nature, 86(51.8%) patients have hemorrhagic stroke and 80(48.2%), ischemic stroke in the rate of 1.59:1(male:female), suggesting that male's outbreak is more than female's. Outbreak age is ranged from 20 years to 90 years in order of 60's, 50's, and 40's. 50's-60's accounts for more than half percentage. 2. For smoking, 73(71.6%) of male patients has smoking experience and their 562% has ischemic stroke. Their cross-analysis for hemorrhagic and ischemic stroke shows significant difference with $x^2=3.90$(p<0.05). 48.6% of patients with smoking experience is ranged from 1 to 10 a day in smoking quantity. 3. For drinking, 90(88.2%) of male patients has drinking experience and their 53.3% has hemorrhagicstroke. Their cross-analysis for hemorrhagic and ischemic stroke shows no significant difference with x2=3.40(p<0.1). 59.3% of patients with drinking experience is classified as a overdrinking group. 4. For obesity, low weight is 8(4.8%): normal, 111(66.9%): excessive, 40(24.1%), and obesity, 7(4.2%). In patients with hemorrhagic stroke, excessive weight and obesity are somewhat high(33.7%). The cross-analysis for male's hemorrhagic and ischemic stork by dividing BMI into more and less than 25 shows no significant difference with x=3.52(p<0.1). 5. For perception of saltness, 21(12.7%) patients eat flat: 76(45.8%) normally, and 69(41.5%), saltily. Many patients with ischemic stroke are classified as a group who eat saltily. The cross-analysis for male's hemorrhagic and ischemic stroke shows signifiant difference with x2=10.99(p<0.05). As this study has small sample and selects inpatient and outpatient in certain local hospital, it is difficult to generalize. But the cross-analysis of male's hemorrhagic and ischemic stroke shows signifiant difference in smoking and perception of saltness. Drinking and obesity are more important factors in hemorrhagic stroke and smoking and perception of saltness in ischemic stroke.

A total of 582 gilts and barrows were analyzed to investigate the regressive relationships to slaughter weight (SW) of variables related to production efficiency and pork quality. Average initial weights and SW were 88.6 and 122.5 kg, respectively, for gilts and 88.7 and 121.4 kg, respectively, for barrows. Average daily gain and gain:feed ratio were not affected by SW. Backfat thickness, which was significantly greater (p<0.01) in barrows (23.3 mm) than in gilts (20.7 mm), increased with increasing SW (0.21 mm/kg; p<0.001). When the 4-notch carcass yield and quality grades were quantified according to an arbitrary 1 point-per-1 notch scale, the former, but not the latter, regressed on SW (-0.64/10 kg; p<0.01). The percent yield of the belly per total lean (overall mean=20.7%) increased with increasing SW (0.37%/10 kg; p<0.001), whereas in other cuts, the SW effect was negligible. The redness of the loin also increased with increasing SW (p<0.05), but other physicochemical characteristics were minimally influenced by SW. In sensory evaluation, effects of SW for fresh and cooked loin, ham, and belly were mostly considered insignificant in terms of quality, albeit statistically significant in several cases. However, positive regressions on SW (p<0.01) of the marbling and acceptability scores of fresh loin as well as the fat:lean ratio of fresh belly were noteworthy. Collectively, SW of approximately 125 kg was maximal for both sexes under the current carcass yield grading, in which 94 kg is the upper weight limit for grade A carcass. However, if the carcass weight limit of the grading was to be removed or broadened, the SW for gilts (but not that for barrows because of their excessive fat content at above 125-kg SW) could be increased to 135 kg or greater without compromising carcass quality.

국내 밤 산업은 박피율을 높이기 위한 목적으로 과도한 칼날박피로 인해 과육 손실이 높아 생산 효율성이 저하되는 문제가 있다. 이에 본 연구에서는 밤 박피 공정의 구동 조건 최적화를 위한 기초 연구로 머신러닝 알고리즘 기반 박피공정 단계별 밤의 중량감모율을 예측할 수 있는 모델을 도출하였다. 6개의 제어조건을 바탕으로 51가지 2단 칼날박피기 실험 세팅 조합을 도출하고 이를 3번씩 반복하여 총 153가지의 데이터를 획득하였다. 인공신경망과 랜덤 포레스트 머신러닝 모델을 이용하여 밤 박피 단계별(1단 박피 후, 2단 박피 후, 최종 배출 후) 중량감모율을 예측하는 머신러닝 모델을 도출하였고, R(coefficient of determiantion), nRMSE(normalized root mean square error), MAE(mean absolute error) 값을 통해 모델의 성능을 평가하였다. 모든 박피 단계에서 인공신경망 모델보다 랜덤 포레스트 모델이 높은 R값으로 우수한 예측 정확도를 가지는 것으로 나타났고, 낮은 nRMSE와 MAE값으로 낮은 예측 오차를 가지는 것으로 나타났다. 최종적으로 랜덤 포래스트 예측 모델이 도출되었으며, 실제로 계측된 중량감모율과 예측한 중량감모율의 오차가 미미함을 확인할 수 있었다. 결과적으로, 도출된 모델은 밤 과육의 중량감모율을 최소화하는 동시에 최대 박피율을 도출할 수 있는 최적 박피공정의 구동 조건을 설정하는 데 활용함으로써, 이를 바탕으로 국내 밤 산업에 이바지 할 수 있을 것으로 예상된다.

Under a typical Mediterranean environment in southern Australia, the evaporation rate increases significantly in hot summers, resulting in highly saline drinking water for grazing animals. Also in the cropping areas, dryland salinity is a problem. Grazing animals under these environments can ingest excessive amount of salt from feed, drinking water and soil, which can lead to a reduction in growth rate. To understand the impact of high salt intake on grazing deer, two experiments were conducted to assess the effect of salt levels in drinking water on feed intake and growth rate of red and fallow weaner deer. The results revealed that fallow deer did not show any abnormal behaviour or sickness when salt level in drinking water was increased from 0% to 2.5%. Feed intake was not affected until the salt content in water exceeded 1.5%. Body weight gain was not affected by 1.2% salt in drinking water, but was reduced as salt content in water increased. Compared with deer on fresh water, the feed intake of red deer on saline water was 11-13% lower when salt level in drinking water was 0.4-0.8%. An increase in salt level in water up to 1% resulted in about a 30% reduction in feed intake (p<0.01). Body weight gain was significantly (p=0.004) reduced when salt level reached 1.2%. The deer on 1% salt tended to have a higher (p=0.052) osmotic pressure in serum. The concentration of P, K, Mg and S in serum was affected when salt level in water was over 1.0%. The results suggested that the salt level in drinking water should be lower than 1.2% for fallow weaner deer and 0.8% for red weaner deer to avoid any reduction in feed intake. Deer farmers need to regularly test the salt levels in drinking water on their farms to ensure that the salt intake of grazing deer is not over the levels that deer can tolerate.

Back extension exercises have been used for rehabilitation of the injured low back, prevention of injury, and fitness training programs. However, excessive loading on low back can exacerbate existing structural weakness. The purpose of this study was to compare muscle activity of low back muscles during back extension exercises. Twenty healthy male subject s were evaluated. Electromyographic (EMG) activities of low back muscles at L1 and L5 level were recorded during seven different back extension exercises and two reference tasks by surface EMG and saved for data analysis. Reference tasks of lifting 20% and 40% of their body weight were included for comparison. The result were as follows: 1) Single-arm extension and single-leg extension exercises on quadruped position appeared to constitute a low-risk exercise for initial extensor strengthening. 2) When arm extension was combined with contralateral leg extension on quadruped position, EMG activities of low back muscles were increased. 3) EMG activity of low back muscles was highest during the trunk extension exercises on prone position. 4) EMG activities of low back muscles during arm and leg extension exercises on quadruped position were less than those of reference task of lifting 40% of their body weight. These result s have important implications for progressive back extensor muscle strengthening exercises in patients with back pain.

The purpose of this study was to determine the outcome of distal femoral osteotomy for distal femoral varus and medial patellar luxation (MPL) grade 4 in small-breed dogs. Radiographs and medical records were reviewed to collect data and plan the surgery in small-breed dogs with MPL grade 4. Computed tomography (CT) imaging was also performed in cases of severe bone deformities. Signalment, weight, medial patellar luxation and lameness grade, radiographic bone union, complications, pre- and postoperative femoral varus angle, passive range of motion, static weight bearing distribution and visual analogue scale scores were recorded. Thirteen corrective distal femoral osteotomies were performed with ancillary and additional procedures in 9 dogs; 4 dogs had staged bilateral procedures; and four stifles were suspected to have partial or complete rupture of the cranial cruciate ligament. One stifle underwent patellar groove replacement. The mean ± SD pre- and postoperative femoral varus angles were 109.15°± 3.71° and 96.30°± 2.97°, respectively. Significant improvements in passive range of motion, thigh circumference and visual analogue scale (VAS) scores were observed. There was no reluxation of the patella. This study suggests that distal femoral osteotomy with traditional and additional procedures provided satisfactory outcomes in patient healing and functional recovery in small-breed dogs with excessive femoral varus angles.

Benign prostatic hyperplasia (BPH) is one of the most common diseases among elderly men. As the old-age population is increasing recently, it is to our interest to observe the growing BPH within them. In BPH, the dihydrotestosterone (DHT) acts as promotes prostate growth. It inhibits enzyme $5{\alpha}$-reductase that is involved in the conversion of testosterone to the DHT activity which reduces the excessive prostate growth. Through experiments, the effects of Phellius linteus water extract performed on the BPH rats were induced by testosterone treatments. For 12 weeks, Sprague-Dawley rats were treated with testosterone for the induction of BPH. Rats were divided into four experimental groups: the not treated group (N), the testosterone injection and D.W treatment group (TN), the testosterone injection and Phellinus linteus treatment group (TP) and testosterone injection and finasteride treatment group (TF). Prostate weight, volume and weight ratio in the TP group and the TF group were significantly lower than the TN group. Testosterone and DHT levels in the TN group were significantly higher than that of the N group. And the TP group was significantly decreased than that of the TN group. While prostates of control rats revealed severe acinar gland atrophy and stromal proliferation; the TP and TF groups showed trophic symptoms and were lined by flattened epithelial cells, thus, the stromal proliferation is relatively low as compared to the TN group. These suggest that Phellinus linteus water extracts may be an useful remedy for treating the benign prostatic hyperplasia.
