The objectives of this study were to compare visual observation and an electronic grazing time method and to evaluate the effects of nutritional plans on intake, grazing behavior and horizontal and vertical locomotion of young bulls in a tropical pasture. Thirty-nine Nellore young bulls with an average body weight of $345{\pm}9.3$ kg kept in pasture were used. The experimental treatments consisted of: restricted: animals kept in a plot with a low mass of forage receiving mineral mixture only; control: animals receiving mineral mixture only; HPHC: a high protein and high carbohydrate supplement; HPLC: a high protein and low carbohydrate supplement; LPHC: a low protein and high carbohydrate supplement; LPLC: a low protein and low carbohydrate supplement. GPS collars equipped with activity sensors were used. Information about head position, latitude, longitude and altitude were recorded. Daytime grazing behavioral patterns monitored by a continuous focal animal recording method was compared to behavior estimated by the activity sensor. Feed intake was estimated by a marker method. The Restricted group presented lower (p<0.05) intake of dry matter and TDN. However, difference in dry matter intake was not found (p>0.05) between non-supplemented and supplemented animals. Difference was not found (p>0.05) in daytime grazing time obtained by visual observation or the activity sensor method. The restricted group showed longer (p<0.05) grazing time (9.58 h/d) than other groups, but difference was not found (p>0.05) in the grazing time between Control (8.35 h/d) and supplemented animals (8.03 h/d). The Restricted group presented lower (p<0.05) horizontal locomotion distance (2,168 m/d) in comparison to other groups (2,580.6 m/d). It can be concluded that the use of activity sensor methods can be recommended due to their being similar to visual observation and able to record 24-h/d. While supplements with high carbohydrates reduce pasture intake, they do not change grazing behavior. Moderate supplementation (until 50% of protein requirement and 30% of energy requirement) of beef cattle on tropical pasture has no effect on daily locomotion.

Objective: A study was conducted to evaluate the varietal differences among faba bean straws and also to assess the potentials of faba bean straws supplemented with concentrate fed at the rate 70% straws and 30% concentrate mixture on feed intake, digestibility, body weight gain and carcass characteristics of the animals. Methods: Forty yearling Arsi-Bale sheep with initial body weight of $19.85{\pm}0.29kg$ (mean${\pm}$standard deviation) were grouped in a randomized complete block design into eight blocks of five animals each based on their initial body weight. Straws included in the study were from Mosisa (T1M), Walki (T2W), Degaga (T3D), Shallo (T4S), and local (T5L) varieties of faba bean and concentrate (2:1 ratio of wheat bran to "noug" seed cake). The experiment consisted of seven days of digestibility and 90 days of feeding trials followed by evaluation of carcass parameters at the end. Results: Local variety had lower (p<0.05) in grain and straw yield compared to improved varieties but higher in crude protein, metabolizable energy contents and in vitro organic matter digestibility. The apparent digestibility of dry matter and crude protein of sheep fed Walki and Mosisa straws were higher than (p<0.05) straws from Shallo varieties. Sheep fed Walki straw had greater (p<0.05) dry matter intake, average daily gain and feed conversion efficiency than sheep fed local and Shallo straws. Slaughter body weight and empty body weight were higher (p<0.05) for sheep fed Mosisa and Walki straws as compared to sheep fed Shallo straws. Apart from this, the other carcass components were not affected (p>0.05) by variety of the faba bean straws. Conclusion: There is significant varietal differences between faba bean straws both in quality and quantity. Similarly, significant variation was observed in feed intake, digestibility, body weight gain and feed conversion efficiency among sheep fed different straws of faba bean varieties with concentrate supplement. Based on these results, Walki and Mosisa varieties could be recommended as pulse crop rotation with cereals in the study area.

This study was designed to examined psychosocial status and nutritional factors(nutrition knowledge, dietary attitudes, eating behavior, dietary intakes) among female university students and to investigate if there were differences in these variables by weight loss attempt. A cross-sectional survey was conducted to 225 female university students in Seoul. Survey instrument was adapted or modified based on literature review, and dietary intakes were assessed using 24-hour recall and CAN-pro. Descriptive statistics, t-test x$^2$-test were used in data analysis. Mean height, weight of subjects were 162.7cm, 51.3kg, and mean BMI was 19.4. One hundred-nine students(48.4%) were grouped into weight loss attempt roup and 116 students were grouped int non-attempt group. According to BMI, 58.7% of weight loss attempt group were underweight, suggesting that unnecessary weight control is common in college women. With respect to psychosocial status, subjects received moderate degree of stress and were slightly satisfied with life. There was no significant difference in stress, social support or self-esteem between the two groups, however, students in non-attempt group were more satisfied with their life(p<0.01) and adapted better in school that students in weight loss attempt group. Subjects scored 14.9${\pm}$2.1 (highest score : 20) on nutritional knowledge, and showed favorable dietary attitudes. Overall, nutritional knowledge and dietary attitudes were not significantly different between the two groups. Common eating problems were irregular meals(71.6%), followed by unbalanced meals and eating-out. Subjects in weight loss attempt group were more likely to change eating habit after entering the university and showed more undesirable eating habit. Dietary intake data indicated hat the energy derived from fat was slightly higher than the recommended level. Most of the nutrient intake was lower than the RDA, particularly, iron and calcium intake was below the 50% of the RDA. Although this study did not reveal significant difference in nutritional knowledge or dietary intake by weight loss attempt, this study showed status of weight control, eating habit and dietary intake in female university students, and provide some information for nutrition education of college women.

After the nuclear accident of the Fukushima Dai-ichi Nuclear Power Plants (FDNPPs) on 11 March 2011, a large amount of radioactive materials has been released into the atmosphere and the ocean. A compartment model is used to evaluate the circulation characteristics and the spatiotemporal concentration distributions of radionuclides in the ocean. In the comparison with observed concentrations of $^{137}Cs$ in seawater, calculated concentrations by the compartment model were well agreed with them. On the basis of these results, we performed evaluation of the effective dose and the cancer risk. In the early stage of the accident, the effective doses from ingestion of the seafood near the Fukushima region were much higher than 1 mSv which is the value of the annual effective dose limit to individual recommended by the International Commission on Radiological Protection (ICRP). However, the effective doses by ingestion of the seafood decreased below 1 mSv as distance from the FDNPPs increased and time passed. In addition, it was estimated that the cancer risks by intake of the contaminated marine products were less than natural occurrence probability of cancer. Consequently, it was inferred that the health risk due to the $^{137}Cs$ was low after since mid-term period of the accident.

This study was done to investigate the health-related habits, dietary intakes and serum lipid levels in overweight and obese women by body mass index(BMI). Subjects were 137 pre-menopausal women aged 19 to 49 years. They were divided by 3 groups, overweight($23{\leqq}BMI<25$), obese($25{\leqq}BMI<30$) and morbidly obese($BMI{\geq}30$) according to their BMI. Body composition was determined by bioelectrical impedance analysis(BIA) method. Dietary intakes were examined by 3-day record method and nutrient intakes were analyzed by the Computer Aided Nutritional analysis program for professionals(CAN-pro 3.1). Serum lipid levels were measured using automatic biochemical analyzer(Selectra E). The average age, height weight and BMI of subjects were 31.7 years old, 159.3cm, 69.4kg, and $27.4kg/m^2$, respectively. Their average consumption of energy were 1712kca1 and 86.4% of estimated energy requirement(EER). Their mom ratio of carbohydrate:protein:fat was 55.2:14.6:30.2. Particularly, the fat consumption of subjects tended to be elevated with increasing BMI. There was no significant difference in nutrient intakes among 3 groups. But the mom intakes of Ca, Fe, vitamin C and Na of all the subjects were 70.1%, 81.2%, 75.7% of recommended intake(RI) and 258.9% of adequate intake(AI), respectively, The intakes of vegetables and seaweeds were significantly higher in morbidly obese group while the intake of fruits was higher in overweight group compared to the other groups. Serum lipid analysis showed that there were no significant differences in the levels of total cholesterol, triglyceride and LDL-cholesterol among the groups. But the serum HDL-cholesterol level of the overweight group was significantly higher than that of the other groups. LDL-/HDL-cholesterol ratio and AI index were significantly higher in the morbidly obese group compared to the other groups. In addition, The systolic blood pressure of morbidly obese group was significantly higher compared to the other groups. Overall data suggest that morbidly obese women have to more concern about reducing systolic blood pressure and nm lipid levels by decreasing their fat consumption and salt intakes as well as loosing body fat. In addition, all the subjects participated in this study have to be careful about their meals and health-related behaviors in order to prevent obesity-related chronic diseases.

This study was performed to determine the dietary risk factors associated with hypertension. The hypertensive group were composed of 112 hypertensive patients (male 53, female 59) who first visited the hypertension clinic and had been diagnosed as having primary hypertension ($SBP{\ge}140mmHg\;or\;DBP{\ge}90mmHg$). The regular visitors or the subjects on special diets or medical therapies were excluded. The normal group consisted of as subjects (male 41, female 54) matched with age and socioeconomic levels. The subjects having higher intakes (above the 75 percentile) in energy, protein, iron, vitamin A or C showed significantly higher hypertension risk estimated with odds ratio after the covariance factors (age, sex and BMI) were adjusted. More than 2400 mg of sodium (6 g of salt) intake was associated with significantly higher risk of hypertension (odds ratio: 1.773, CI: 1.014-3.014 for $SBP{\ge}140mmHg$; odds ratio: 2.373, CI: 1.359-4.215 for $DBP{\ge}90mmHg$). Hypertensive group showed significantly increased intakes of vegetables and fish and shell fish compared to the normal group. When the vegetable intakes were classified into Kimchi, fresh vegetables and cooked vegetables with seasoning, the hypertensive group was observed as having higher intakes of Kimchi and cooked vegetables with seasoning. The intakes of highest quartile for vegetables (${\ge}327g/day$) (odds ratio: 3.164, CI: 1.740-5.752), fish and their products (${\ge}102g/day$) (odds ratio: 2.756, CI: 1.486-5.109), grains(${\ge}311g/day$) (odds ratio 2.393, CI: 1.186-4.832), meats and their product (${\ge}106g$) (odds ratio: 2.210, CI: 1.225 - 3.987) compared to the lower were significantly associated with the higher risk of hypertension estimated with DBP (${\ge}90mmHg$) after covariance factors were adjusted. In conclusion, our findings confirm that higher intake of energy or sodium are associated with the increased risk of hypertension. Because increased intake of vegetable or fish was associated with the higher risk of hypertension, in contrast with the finding of western countries, choosing or preparation of vegetables or fish with reduced salt is recommended.
