The principal objective of this study was to determine the effects of diet knowledge and perception on diet practice behavior among university students. Data were collected between March and April of 2005 from 523 male and female university students in Seoul and Chungbuk, via a self-administered questionnaire. The subjects included 217 male students (41.5%) and 306 female students (58.5%), and 52.0% of the subjects were 21-23 years old. With regard to residence type, 42.6% of the subjects lived in the dormitory, home (29.1%) self-boarding (19.5%) and meal (8.8) were in the order. The average weights and heights of the subjects were as follows: 70.9$\pm$9.0 kg and 174.3$\pm$4.4 cm in the male students and 53.9$\pm$5.9 kg and 161.3$\pm$4.5 cm in the female students. The average BMI values of the male and female students were 23.4$\pm$2.5 and 20.8$\pm$2.1, respectively. The average nutritional knowledge scores were as follows: 1.96 out of 3.0, dietary habit (2.13), nutrition (2.0), exercise (1.98), preferred food (1.90), and chronic disease (1.79). We noted no significant differences between the male and female subjects in terms of scored points. Nutritional knowledge by gender and residence type were shown to be significantly different--the male subjects had higher scores for exercise than did the female subjects. The self-boarding subjects had significantly lower scores with regard to nutritional knowledge and chronic disease. The experience and duration of previous diet practice were also significantly different with regard to gender and residence type. The male subjects tended to conduct diet practice for longer periods than females. The self-boarding students reported more attempts at diet behavior, but for shorter durations. The results show that the nutritional knowledge and diet practice behavior of the subjects were influenced by gender and residence type.

A 6-year-old neutered male Poodle with a body weight of 2.7 kg was diagnosed with a congenital extrahepatic portoazygos shunt presented with progressive hepatic encephalopathy. Five days after surgical attenuation, the patient showed post-attenuation neurological signs (PANS) such as generalized tonic-clonic seizure, dull mentation, and tremor. PANS were successfully managed with antiepileptic drugs, but third-space fluid accumulation (ascites and peripheral edema) and phlebectasia were newly identified, suggesting marked portal hypertension (PHT). Telmisartan, spironolactone, carvedilol, and prednisolone were sequentially administered. Three months after surgery, both abnormal clinicopathological values such as anemia and hypoalbuminemia, and clinical signs completely resolved. Herein, we report successful management strategies for PANS and PHT in a dog following surgical attenuation of a congenital portoazygos shunt.

Understanding adipocyte development in fetus during bovine pregnancy is important for strengthening fattening technology. Additionally, nutritional level of dams during pregnancy has the potential to improve offspring growth and fat development. The purpose of this study is to evaluate the intramuscular adipocyte development and expression level of related genes in bovine fetus, and the effect of increased crude protein (CP) intake during pregnancy on the growth performance and carcass characteristics of male offspring. Eighty six pregnant Hanwoo cows (average body weight, 551.5 ± 51.3 kg, age 5.29 ± 0.61 y) were used. Fetuses were collected at 90, 180 and 270 d of gestation from 18 pregnant Hanwoo cows. The remaining 68 pregnant cows were randomly assigned to 2 feeding groups. The control (CON) group was provided the standard protein diet (n = 34), and treatment (TRT) group was provided a diet with a 5% increase in CP intake (n = 34). Male offspring were divided into two groups according to protein treatment of the pregnant cows: CON male offspring (CON-O) and TRT male offspring (TRT-O). Intramuscular adipocytes were found in the fetal skeletal muscle after 180 days of gestation. Male calf's birth weight increased in the TRT group compared to that in the CON group (p < 0.002). The final body weight (p < 0.003) and average daily gain (p < 0.019) of male offspring were significantly higher in TRT-O than in CON-O. The feed conversion ratio was also improved by 10.5% in TRT-O compared to that in CON-O (p < 0.026). Carcass weight was significantly higher in the TRT-O group than that in the CON-O group (p < 0.003), and back fat was thicker in the TRT-O group (p = 0.07). The gross receipts and net income were higher in TRT-O than in CON-O (p < 0.04). Thus, fetal intramuscular fat can be formed from the mid-gestation period, and increased CP intake during pregnancy can increase net income by improving the growth and carcass weight of male offspring rather than intramuscular fat.

This study researches an obesity index and the realities of physical activity of elementary school children and provide basic data to instruct correct physical activity for low weight and obese children. The subject was 813 Elementary School Children of grade 4-6 in Kyungju and data were collected with a Physical Activity Questionnaire from YHS, USA. The collected data were analyzed with real number, percentage, average and standard deviation techniques. The range was by SPSS WIN. Both of them were in the normal range, between -38.3 and 77.7, between low weight and obesity. The results are as follows : 1. An Obesity index according to grade and sex: the average obesity index of 423 boys was $7.56{\pm}15.7$, for girls it was $2.56{\pm}14.3$. Both of them were in the normal range, between -38.3 and 77.7. There were low weight($-38.85{\pm}0.9$) students as well as obese, including extremely low weight children ($-38.85{\pm}0.9$) and extremely obese children. 2. On the whole, in the Frequency of the 25 item physical activities breakdown, children reported to watch TV 1. ($2.7{\pm}0.6$), or do homework($2.1{\pm}0.9$), more than three-fourths of the week, male children, however, played more football($2.0{\pm}0.9$). As male obese children do less MET5, MET8(highly active activity) than male normal children, it was also discovered that low weight children do more severe activity in MET8(high activity). In female cases, it was revealed that neither do highly intense activity. 3. In physical activity, male children received higher points than female children with $92.94{\pm}37.95$ to $74.46{\pm}29.50$. On the whole, male and female obese children had lower score than normal children. 4. As for attitude toward physical activity, male children($31.96{\pm}4.37$) had a positive attitude than female children ($29.57{\pm}3.89$), but obese male children had a negative attitude regarding activity viewed as normal. Therefore, in preventing obesity in elementary school children the treating of under-weight children should be included in the obesity program so as to prevent mal-nutrition or deficiency. It is needed to instruct obese children to carry out intensive work-outs at least 3 times a week through systematic programs. It is also needed that parents and teachers educate elementary school children from an early age with information on the frequency and intensity of work-outs to prevent obesity. It is also desirable that children be educated to carry out physical activities that address their specific needs. As a result of this study, obesity management must be started from elementary school and children should be instructed to act in high-intensity actirities when they spend leisure time.

점박이응애(Tetranychus urticae Koch)의 감수성계통(S)과 dicofol 저항성계통(R)을 공시하여 dicofol저항성의 안정성을 조사하였다. Dicofol 저항성계통(저항성비 23.0)의 약제도태없는 조건하에서 사육된 암컷성충의 dicofol에 대한 저항성 수준은 1년이 경과된 후에도 변화가 없었다. 그러나 1년 이후부터는 감소하기 시작하여 2년째에는 저항성비가 15.8배, 3년째에는 10.7배로 감수성쪽으로 기울었다. 점박이응애의 dicofol 저항성계통과 감수서계통의 상호교배 $(R_{female}\timesS_{male},R_{male}\times S_{female})$에서 얻어진 세대별 약제 감수성도 세대가 경과됨에 따라 감수성쪽으로 기울었다.
