  • This research aimed to define the energy requirement of Dorper and Hu Hybrid $F_1$ ewes 20 to 50 kg of body weight, furthermore to study energy requirement changes with age and evaluate the effect of age on energy requirement parameters. In comparative slaughter trial, thirty animals were divided into three dry matter intake treatments (ad libitum, n = 18; low restricted, n = 6; high restricted, n = 6), and were all slaughtered as baseline, intermediate, and final slaughter groups, to calculate body chemical components and energy retained. In digestibility trial, twelve ewes were housed in individual metabolic cages and randomly assigned to three feeding treatments in accordance with the design of a comparative slaughter trial, to evaluate dietary energetic values at different feed intake levels. The combined data indicated that, with increasing age, the net energy requirement for maintenance ($NE_m$) decreased from $260.62{\pm}13.21$ to $250.61{\pm}11.79kJ/kg^{0.75}$ of shrunk body weight (SBW)/d, and metabolizable energy requirement for maintenance (MEm) decreased from $401.99{\pm}20.31$ to $371.23{\pm}17.47kJ/kg^{0.75}$ of SBW/d. Partial efficiency of ME utilization for maintenance ($k_m$, 0.65 vs 0.68) and growth ($k_g$, 0.42 vs 0.41) did not differ (p>0.05) due to age; At the similar condition of average daily gain, net energy requirements for growth ($NE_g$) and metabolizable energy requirements for growth ($ME_g$) for ewes during late fattening period were 23% and 25% greater than corresponding values of ewes during early fattening period. In conclusion, the effect of age upon energy requirement parameters in the present study were similar in tendency with previous recommendations, values of energy requirement for growth ($NE_g$ and $ME_g$) for Dorper and Hu crossbred female lambs ranged between the NRC (2007) recommendation for early and later maturating growing sheep.

  • This study was carried out in order to determin optimum irrigation requirements and water management practices for normal growth of dry field crops in reclaimed tidelands, and apply m planning of the irrigation projects. Desalinization experiments were performed by water management practices in the experimental field with high salt concentration, and growth experiments were conducted by irrigation point treatments using tomato and beet with relatively high salt tolerance. The results obtained from this study were summarized as follows : 1. Leaching or rinsing-leaching method was found to be effective in desalinizing the reclaimed tideland with rather high permeability. In this case, the water requirement for desalinizing the root zone layer of 40cm in depth, was estimated to be 1,200mm in depth. 2.The gypsum treatment in the desalinization of reclaimed tidelands, was ineffective in water requirements ; however, it could produce the desired effect in the facility of desalinization and the shortening of desalinization period with the sustaining permeability, in case of the desalinization by leaching method. 3.The optimum irrigation point which maintains the salt concentration within salt tolerance and maximizes the crop yield in reclaimed tidelands of silt loam soil, was found to be pF 1.6 in tomato and pF 1.8 in beet. The interval of irrigation date within 2 days was proved to he effective in both cases. 4.The optimum irrigation requirement and the water reguirement for the prevention of salt rise during the growing period after transplanting, were estimated to be 602mm(6.7mm/day) and 232mm for tomato, respectively. 5.The optimum irrigation requirement and the water requirement for the prevention of salt rise during the growing period after transplanting, were estimated to be 261mm(3.7mm/day) and 66mm for beet, respectively.

  • This study was conducted on the nutritional status of 1,805 patients with allergic diseases (atopic dermatitis, allergic rhinitis, and asthma) aged 19 to 64 years according to their state of depression, based on the data from the Korea National Health and Nutrition Examination Survey (KNHANES). The Patient Health Questionnaire-9 (PHQ-9) was used to diagnose depression. Subjects with a score of 10 or more were categorized into the depression group (n=152) and the rest into the non-depression group (n=1,653). The results of this study were as follows: The proportion of women (75.7%) was higher than that of men (24.3%) in the depressed group (P<0.01). In terms of energy intake per 1,000 kcal, both men and women in the depressed group showed a lower energy intake than the non-depressed group and this intake was less than the estimated energy requirement (EER). The nutrient intakes of protein, calcium, phosphorus, iron, vitamin A, thiamine, riboflavin, niacin, folic acid, and vitamin C were below the estimated average requirement (EAR). Also, the intakes of fiber and potassium were less than the adequate intake (AI) (P<0.001). In the lifestyle parameters, the ratio of eating alone at lunch was 54.1%:33.1%, indicating that more than half of the depression group ate alone. In conclusion, it was observed that the nutritional status of allergic disease patients was imbalanced. The nutritional imbalance was due to insufficient energy intake and inadequate intake of nutrients, which was below the average requirements of vitamins and minerals and this was more evident in the depression group than in the non-depression group.

  • 원초적 확률주의자들은 명제가 경험을 표상한다는 것을 거부한다. 그러나 경험의 영향은 다른 믿음에 전파되고, 다른 사람과 소통될 수 있어야 하기 때문에 명제와 다른 방식으로 경험, 혹은 경험의 영향을 표상할 수 있는 대안을 찾아야 한다. 그들이 제안하는 경험의 영향을 표상하는 유력한 대안은 베이즈 인수이다. 왜냐하면 베이즈 인수는 사전확률의 영향을 제외하고 있으며, 교환성 역시 성립하기 때문이다. 본 논문은 베이즈 인수만이 그런 역할을 하는 것이 아니라고 주장한다. 즉 베이즈 인수의 대안으로 제시된 q(E|$N_p$) 역시 사전확률의 영향이 제외되어 있으며, 교환성 또한 성립한다는 것을 보인다. 그리고 더 나아가 q(E|$N_p$)는 베이즈 인수가 결여한 프래그마틱한 장점을 가진다고 주장한다.

  • The objective of this study is to investigate geochemical characteristics of mine wastes including tailings in various abandoned mines in Korea. Tailings and wastes were sampled in and around 39 metalliferous mines, and analysed heavy metal concentrations including Cd, Cu, Pb and Zn extracted by 0.1N HCl and aqua regia by Atomic Absorption Spectrometry. Measurements of paste pH and lime requirement were carried out to examine a general geochemical characteristics of the materials. Lots of mine wastes were characterized by very low pH values of 2 to 4 and high lime requirement to control neutralization of the wastes. In addition, elevated levels of heavy metals were found in various mine wastes extracted by both 0.lN HCl and aqua regia. Because the mine wastes can be dispersed into the downstream by clastic movement and wind-blow, it is necessary to control the materials with a proper method for their reclamation.

  • Two feeding trials were conducted to evaluate the effects of inclusion levels of dietary vitamin and trace mineral (VTM) premixes on growth and nutrient digestibility in growing pigs. A total of 112 pigs ($24.82{\pm}3.22kg$) were employed for 49 days (exp. 1), and 168 pigs ($21.64{\pm}1.41kg$) for 40 days (exp. 2) in completely randomized block designs. Treatments were: 1) 100%, 2) 150%, 3) 200% and 4) 250% NRC (1998) requirement of VTM in exp. 1, and the ratio of vitamins to trace minerals at 1) 100:100%, 2) 100:150%, 3) 150:100% and 4) 150:150% of NRC (1998) requirement in exp. 2. Basal diets for feeding trials were formulated to contain 3,310 kcal ME/kg and 18% crude protein, and contained 0.25% chromic oxide as an indigestible marker for digestibility trials. Increasing dietary VTM premix in growing pigs had linear and quadratic effects (p<0.05) on ADG, and feed conversion ratio was also improved (p<0.05) as VTM premix was increased by 150-250% of NRC (1998) requirements in exp. 1. Adding vitamin to trace mineral premixes at 150% NRC (1998) over the control improved (p<0.05) ADG and feed efficiency in growing pigs, but performances were not improved by vitamin nor by trace mineral premixes alone (p>0.15) (exp. 2). There were no differences (p>0.05) in the digestibilities of energy, crude protein and fat among dietary treatments. However, increasing dietary VTM premix in growing pigs had a linear effect (p<0.05) on the digestibilities of calcium and phosphorus. The 200 or 250% fed group showed improved (p<0.05) calcium digestibility, and 250% fed group also showed improved (p<0.05) phosphorus digestibility as compared to 100% or 150% fed group (exp. 1). The digestibilities of Ca and P were higher (p<0.05) in 150% addition of vitamins than in 150% addition of trace minerals in the diet (exp. 2).

  • The objectives of this study were to characterize the health status, the requirement of home nursing care, and dependency of daily life of the elderly so that the result could be used to provide basic data necessary for establishing home nursing care practices. The study subjects were 249 elders over 65 years old who resided at home in low income areas of three districts in Pusan. The field survey was conducted from December 27, 1993 through January 27, 1994, with a structured questionnaire. Statistical analysis was done by X²-test and Student's T-test using SPSS/PC/sup +/ program. The result were as follows; 1. Alcohol drinking rate was 50.0% for men and 27.7% for women, and cigarette smoking rate was 77.8% for men and 27.1% for women. 92.9% of elders aged 65-75 exercised regularly as compared to 81.9% of elders aged 75 and over(p<0.05). 2. 63.9% of male and 85.9% of female elders had chronic diseases showing singnificant differences(p<0.01), and both sexes had 1.7 kinds of chronic diseases in average; musculoskeletal diseases were the most common in 25.7%, while 6.8% of the elderly had cardiovascular diseases. 3. Partially movable elderly was 6.9% for men and 6.8% for woman, showing 47.1% of causes being cerebrovascular accidents. 4. The home nursing requirement was the highest for medication(66.3%), intramuscular injection(53.8%), and measurement of blood pressure·body·temperature·pulse rate(47.0%). 5. Among Physical Activities of Daily Life, bathing(10.4%) and movement(4.0%) showed high dependency rates, and among Instrumental Activities of Daily Life, phone calling(25.3%), shopping(24.5%), going out by bus(22.5%) showed high dependency rates. 6. For five categories of home nursing showing high requirements such as physical health examination, blood pressure·temperature·pulas rate measurements, medication, and intravascular injection, the requirements were different by age groups, education, and marital status(p<0.05).

  • Objective: The main objective of this study was to evaluate the effect of different feeding levels of a total mixed ration silage-based diet on feed intake, total tract digestion, enteric methane emissions, and energy partitioning in two beef cattle genotypes. Methods: Six mature bulls (three Thai natives, and three Thai natives - Charolais crossbreeds) were assigned in a replicated $3{\times}3$ Latin square design, with cattle breed genotype in separate squares, three periods of 21 days, and three energy feeding above maintenance levels (1.1, 1.5, and 2.0 MEm, where MEm is metabolizable energy requirement for maintenance). Bulls were placed in a metabolic cage equipped with a ventilated head box respiration system to evaluate digestibility, record respiration gases, and determine energy balance. Results: Increasing the feeding level had no significant effect on digestibility but drastically reduced the enteric methane emission rate (p<0.05). Increasing the feeding level also significantly increased the energy retention and utilization efficiency (p<0.01). The Thai native cattle had greater enteric methane emission rate, digestibility, and energy utilization efficiency than the Charolais crossbred cattle (p<0.05). The daily metabolizable energy requirement for maintenance in Thai native cattle ($388kJ/kg\;BW^{0.75}$, where $BW^{0.75}$ is metabolic body weight) was 15% less than that in Charolais crossbred cattle ($444kJ/kg\;BW^{0.75}$). Conclusion: Our results suggested that the greater feeding level in zebu beef cattle fed above maintenance levels resulted in improved energy retention and utilization efficiency because of the reduction in enteric methane energy loss. The results also indicated higher efficiency of metabolisable energy utilization for growth and a lower energy requirement for maintenance in Bos indicus than in Bos taurus.
