One of the problems in increasing rice production is getting lines or varieties that have high adaptability so that able to produce maximum production in a variety of environmental conditions. One strategy that can be done to get adaptive varieties is through the improvement of native varieties. This research was conducted in rain fed paddy field, Aceh province, Indonesia from June to September 2014. The texture of the soil was clay-loam with the soil pH ranged from 6.5-6.7. Five potential progenies of rice from crossing between native Indonesian rice with introduced rice varieties consist of C3, C4, S3, S5, S6 were used in this study. Besides that, one national rice variety Ciherang also used as a comparison. The plants were growth in the plot with the size of $2m{\times}1.4m$ with plant distance was $20cm{\times}20cm$. The fertilizers used in this study were Urea, NPK, and KCl. Randomized block design with 6 rice progenies/variety and 3 replications were used in this study. There were 18 experimental units and each experimental unit had 10 samples for the sources of data. The variables that were observed in this study including plant height at harvesting time, number of productive tiller, the percentage of empty grains and filled grain per panicle, weight of filled grains per hill, weight of filled grain per plot and yield potential per hectare. Analyzed were also conducted for the depth of root penetration, dry-root weight, dry-shoot weight, shoot-root weight ratio and its correlation with the weight of filled grain per hill. The research results show that there was significant difference on plant height at harvesting time, number of productive tillers, the percentage of empty grains and filled grain per panicle, weight of filled grains per hill, weight of filled grain per plot and yield potential per ha (p>0.01) among the treatments. In addition, depth root penetration, dry-root weight, dry-shoot weight, shoot-root weight ratio also had significant difference (p>0.01) among the treatment. The highest plant at harvesting time was found in S6, reaching 129.8 cm and the shortest plants was found in C3 reaching 107.5 cm. The largest number of productive tillers and the highest percentage of filled grains per panicle were found in Ciherang reaching 10.5 tillers and 80.7% respectively. Ciherang also had the heaviest weight of filled grains per hill and per plot reaching 21.1 g and 2.18 kg respectively. Whereas, S6 had the lowest number of tillers and the lowest percentage of filled grain per panicle.. The highest yield potential per ha was found in Ciherang reaching 7.79 tons. Among the progenies, S5 had the highest yield potential reaching 5 tons/Ha. The result also showed significant relationship between shoot-root weight ratio with weight of filled grains per hill. The highest value of shoot-root weight ratio (1.57) in Ciherang is thought had closed relationship with its yield potential.
This study was carried out to investigate the eating habits and preference of snacks for students in Chungnam province. Questionnaires were collected from 333 students, which were divided into male and female, food nutrition majors and non-majors, and weight groups according to BMI. The results obtained were as follows; 1. 62.8% of students responded that they were healthy. A significant difference on the health question was found between male and female students (p<.05). Male students responded more positively to the question related to health than the females, saying they felt healthy (71.1%). There was no significance between the different majors, but a significant difference was found in weight groups compared to normal groups (p<.05). 2. 72.1% of respondents enjoyed omnivorous meals. The significant differences were not found in gender groups and major groups. However, there was a significant difference between the weights of the students (p<.01). 3. Most of the students liked sweet foods (42.3%). The significant difference was found in gender groups for food tastes. The male students preferred spicy foods (37.0%), but the females preferred sweet foods (49.5%). Taste for the major and weight groups was not significantly different. 4. 50.5% of respondents answered that they frequently ate snacks. The significance was found in gender groups (p<.01). The females had a higher intake of snacks than the males. The significant difference for taste was not shown in the major group, but was found in the weight groups (p<.05). 5. Students preferred snacks and candy (16.8%). The males liked dairy products (19.3%), while the females preferred snacks and candy (23.7%). Students majoring in food nutrition have a tendency to prefer snacks (32.1%). Appropriate calorie intake and desirable eating habits should be recommended for healthy control and maintenance of students through eating nutritionally balanced foods.

Objectives : This study was performed to investigate the effect of water extracts from Lagocephalus wheeled with several herbs(LW) on hyperlipemia and liver damage induced by alcohol. Methods : Except for the normal group, we fed rat on 25% alcohol for 55 days. And each extract was administrated for the same period. We measured the serum component in rat's blood, body weight and weight of liver. Results : At first, we observed effects of LW on hyperlipemia induced by alcohol. LW group didn't show significant increase of total cholesterol in comparison with those of the control group. LW group didn't show significant increase of HDL(High-Density lipoprotein) cholesterol in comparison with those of the control group. LW group showed significant decrease of triglyceride in comparison with those of the control group. LW group showed significant increase of body weight in comparison with those of the control group in 4weeks and 8weeks. LW group showed significant increase of liver weight in comparison with those of the control group. At second, we observed effects of LW on liver damage induced by alcohol. LW group showed significant decrease of ALP, GOT, GPT and LDH in comparison with those of the control group. Conclusions : Reviewing these experimental results, it appears that water extracts from Lagocephalus wheeleri with several herbs have pharmaceutical efficacy on hyperlipidemia and liver damage induced by alcohol. Therefore further additional study should be conducted to elucidate in depth the pharmaceutical efficacy of this.

This study assessed the amount of energy consumed and fat deposition after endurance training in order to review the effect of 4-week endurance exercise on resting metabolic rate of a mouse during and after exercise and the effect of exercise. A total of 19 seven-week-old ICR male mice were used as the study subject. Those mice were divided into sedentary group (Sed) and trained group (Tr) after a week of environment adaption. The Tr group was trained with endurance exercise five times a week for four weeks. Weight and the amount of food intake were daily weighed and resting metabolic rate and metabolic rate after exercise were assessed before starting exercise and on the fourth week after training. Metabolic rate during exercise were measured four weeks after training. At the end of breeding period, statistically significant difference was shown in weights of trained and sedentary groups (p < 0.05). During a resting period, no significant difference was shown in oxygen intake, respiratory exchange ratio, and the amount of carbohydrate and fat oxidized. Moreover, no significant difference was shown in excess post-exercise oxygen consumption (EPOC) of an hour period after training. In contrast, the maximal oxygen uptake (VO2 max) was approximately 11.1% higher in trained group after training compare to before. However, there was no significant difference in respiratory exchange ratio and carbohydrate and fat oxidization. During exercise, oxygen uptake, carbon dioxide production, and respiratory exchange ratio in energy metabolism during exercise showed no significant difference. However, significant difference was exhibited in the amount of fat oxidized in both groups. Summing up those results, endurance exercise could be concluded to be effective in weight control. However, weight loss is thought to be resulted from increase in fat oxidization during exercise unlike the conclusion made from previous studies where weight loss is prominently influenced by energy metabolism during a resting period and increased fat oxidation during post-exercise recovery. All experimental procedures were carried out at the Animal Experiment Research Center of Konkuk University. This study was conducted in accordance with the ethical guidelines of the Konkuk University Institutional Animal Care and Use Committee.
A trial with twenty-four newly weaned Awassi lambs (initial body weight=21.5$\pm$0.8 kg) was conducted using a 3$\times$2 factorial design to study the effect of feeding three sources of protein supplements (soybean meal (SBM), sunflower seed meal (SSM), and cottonseed meal (CSM)), either untreated or formaldehyde-treated on the growth performance and carcass traits of Awassi lambs. Lambs were randomly assigned to one of the six diets (4 lambs/treatment diet) and were individually fed for a period of 107 days. Experimental diets were isonitrogenous and isocaloric. Final live weight and average daily gain (ADG) were affected by both source of protein and formaldehyde treatment (undegradable protein). Lambs fed untreated diets had better (p<0.01) daily gain compared to those fed formaldehyde-treated diets. Similarly total feed intake per animal was significantly (p<0.05) affected by protein source and formaldehyde treatment. Formaldehyde treatment caused a significant decrease (p<0.01) in feed intake compared to lambs fed untreated diets. Feed requirement per unit of gain was not affected by formaldehyde treatment during all periods of the experiment except for the second period (the second 28 day period), whereby untreated SBM, SSM and CSM had better feed conversion ratio (FCR) than the treated groups. Source of protein had a moderate effect (p<0.10) on FCR but had a significant effect (p<0.05) on hot and cold carcass weight, digestive tract empty weight and liver weight, with lambs fed SBM having higher values than lambs fed SSM and CSM diets. Supplementation with undegradable protein had a significant effect (p<0.05) on dressing-out percentage (p<0.05), final live weight, and hot and cold carcass weight (p<0.01). The lower values pertain to lambs fed treated diets compared to lambs fed untreated diets. In general, there were no significant differences among all carcass linear dimensions, carcass cut weights and dissected loin tissue weights for both treatments (protein source and formaldehyde treatment). Supplementation with undegradable protein but not the source of protein resulted in significantly higher dissected leg total bone weight (p<0.05), tibia and femur weight (p<0.05), and femur length (p<0.01) at the same carcass weight. Results suggest that the treatment of SBM, SSM and CSM with formaldehyde did not improve efficiency of feed utilization, lamb performance or carcass traits and that the SBM diet resulted in an increase in lamb performance compared to other experimental diets.
Highly significant correlation (p < 0.001) was found between body weight and chest circumference of the local Katjang and cross-bred (local Katjang ♀ ${\times}$ German Fawn ♂ bucks under study. Increase in body length, chest circumference, depth of chest and height at withers (p < 0.001) reflected significantly the increase in body weight of the bucks. At the same age the cross-breds were bigger than the indigenous breed. No significant correlation was detected between body weight and scrotal circumference, or the latter with sperm counts in both buck types under study. However, the fluid portion of the semen increased in acidity and volume, the latter being significant (P < 0.01) in the local Katjangs, with increase in scrotal circumference. Although the effects of body condition on buck libido of both groups were not significant, the reaction time taken to mount the teaser females were significantly diminished (p < 0.001) with better body condition, at least in the local Katjangs. The reaction time gad an inverse, though not necessarily significant, relationship with semen characteristics such as volume, pH (in local Katjangs, p < 0.05), concentration, color (in cross-breds, p < 0.05), agglutination and mass movements in both phenotypes.
The purpose of this study was to investigate the body mass index and food habits of female university students (nutrition majors) in Seoul. The means of height, weight and BMI were 161.22${\pm}$4.63cm, 52.76${\pm}$6.59kg, and 22.20${\pm}$3.98, respectively. Subjects were divided into 3 groups based on BMI. The ratio of underweight, normal, and overweight students was 25.2%, 56.3%, and 18.5%. respectively. There were significant differences in the recognition rate of body shape and the way to maintain health by BMI. And self satisfaction rate of body shape was significantly higher in underweight subjects compared with others. There was no significant difference in the rate of activity and exercise, food behavior, intake frequency of various foods, intake of convenience food and carbonated drink according to BMI. Weight and body fat of subjects had a significant correlation with BMI. and height, frequency of taking food, frequency of meals, food behavior, intake food, health and exercise consciousness rate showed no correlation with BMI.
Decay and mold resistance of zinc borate (ZB) and calcium borate (CB) modified oriented strandboard (OSB) from southern mixed hardwood and southern yellow pine was investigated in this study. Brown rot fungus Gloeophyllum trabeum and white-rot fungus Trametes versicolar were used to examine the decay resistance of the OSB. The OSB test specimens were colonized by brown and white rot fungal mycelium in both the brown and white-rot culture bottles after 8 and 12 weeks, respectively. The wood species and fungus type had the significant effects on the decay resistance. Brown rot decay was evident for all untreated southern pine and mixed hardwood controls. The white-rot decay, however, did not show significant weight loss at both species control samples. The incorporation of ZB and CB composites provides suitable protection against brown-and white-rot fungi. No significant weight loss was observed from the borate treated OSB.
Objectives The purpose of this study is to find out the effect of KyungOcGogamibang(KOGE) on the growth of rats. Methods First of all, we divided male Sprague-Dawley rats into 4 groups(KOGE1, KOGE2, KOGE3 and control group). Then KOGE1, KOGE2 and KOGE3 groups were administered with KOGE water extracts once a day at a dosage of 250, 500, 1,000mg/kg respectively for 3 weeks. The control group was administered with normal saline in the same manner. We measured the rat's body weight, amount of body weight increased, length of femur, serum GH, serum IGF-Ⅰ, serum TSH and serum testosterone after each week of administration. Results 1. There were significant changes of the rat's body weight, the length of the femur, the level of GH, IGF-Ⅰand TSH in KOGE1 groups. 2. There were significant changes of the rat's body weight, the length of the femur, the level of IGF-Ⅰand TSH in KOGE2 groups. 3. There were significant changes of the rat's body weight, the length of the femur, the level of IGF-Ⅰand TSH in KOGE3 groups. Conclusions According to the results above, rat in KOGE group have been increased their body weight, length of femur, serum GH, serum IGF-1 compared to the control group. This study shows that groups of KOGE have an effect on promoting the growth, thus it is expected to treat growth problems for children.
