Four-week toxicity of EPO(erythropoietin) was investigated using New Zealand White rabbits according to the established regulations of Korean National Institute of Safety Research. Rabbits were administered intravenously seven days per week for 28 days with dosage of 0, 80, 400 and 2000IU/kg B. W./day. Animals administered with EPO showed no significant changes of body weight, water consumption and feed consumption, and no clinical signs and death. They were not significantly different from the control group in hematological and serum biochemical analysis, urinalysis, prothrombin time, and partial thromboplastin time. In this study, we concluded that EPO had no toxic effect in the New Zealand White rabbits when they were administered intravenously below 2000IU/ kg B.W./ day for 28 days.

The objective of this study was to determine the safety test for propolis in Beagle based on blood count, serum biochemistry, and electrolyte. Total six beagle dogs were assigned to this experiment. To investigate the safety of propolis in beagle dogs, we performed oral administration of propolis (5%) for 8 weeks. Among six beagles, three beagle dogs were randomly allocated to the control group which were fed only regular fodder, and the other three dogs were assigned as the treatment group which were fed regular fodder and propolis (5%). No clinical signs were observed in neither group throughout the experimental period. During the experimental period, there were no significant change in feed intake, water consumption, and body condition. Also, there were no statistically significant differences in hematological and biochemical analyses between the control group and the treated group. Our safety study showed that oral consumption of propolis did not cause any toxicological effects in beagle dogs.

Generally, in machining operations, the required machining performance can be obtained by properly combining several machining parameters properly. In this research, we construct a simulation model, which that predicts the relationship between the input variables and output variables in the turning operation. Input variables necessary for the turning operation include cutting speed, feed, and depth of cut. Surface roughness and electrical current consumption are used as the output variables. To construct the simulation model, an Artificial Neural Network (ANN) is employed. With theIn ANN, training is necessary to find appropriate weights, and the Ant Colony Optimization (ACO) technique is used as a training tool. EspeciallyIn particular, for the continuous domain, ACOR is adopted and athe related algorithm is developed. Finally, the effects of the algorithm on the results are identified and analyzsed.

Although renewable energy sources are more environmentally friendly than fossil energy sources, it is far more costly, considering current technological standards. It would not present many competitive advantages in the power market. If the renewable electricity is viable in the market, the government should take 'visible' actions to compensate production costs. Popular policies, such as Feed-In-Tariff and Renewable Portfolio Standards, can help to attract investors into generators of renewable electricity. But presently, they are mainly financed through a undifferentiated increase of electricity bills and occasionally confronted with the opposition of the electricity consumers. And most policies tend to focus on increasing the supply of renewable electricity with little consideration toward elevating the motivation of consumers. This study evaluates the potential of environmentally friendly energy consumption and examines the 'green pricing' program which realize the potential.

Large amounts of poultry processing wastes including blood, feathers, offal, bones and manure are produced annually from the poultry industry. Over the past years, these products have been wasted and now there is a need for the treatment of these processing wastes. These processing wastes could be either discarded, a rather expensive option considering the cost of sewage disposal, or processed into animal feed or food for human consumption. This paper mainly deals with the various methods through which the different poultry processing wastes have been further processed and/or utilized for human flood or animal consumption. This paper also reviews steps involved in general poultry processing.

Building energy simulation has become a useful tool for predicting cooling, heating and air-conditioning loads for facilities. It is important to provide building energy performances feed back to the mechanical and electrical system operator and engineer for energy conservation and maintenance of building. From this research, we set up the typical weather data of location, basic description of building, geometric modelling data and the specification of Installed primary HVAC system for establishing the simulation model about energy consuming that take place in multipurpose building complex. The simulation tool of building energy - EnergyPlus (DOE and BLAST based simulation S/W), it has been used and accomplished calculations and analyses for evaluating the effect of the system types and operating condition of central HVAC plant on the building energy consumption. In this paper, we offer comparison and simultaneous results those involve electricity consumption pattern and amount between actual operation versus EnergyPlus simulation to the object building during summer season.

This paper approaches Sir Thomas More, Coriolanus, Pericles in terms of the relationship of food to national identity. These three plays examine ways in which food is essential to what constitutes English national identity, and food shortages give rise to riots thereby throwing everyday life into disorder. In Sir Thomas More food shortages are caused by foreign foodstuff and foreign habits of consumption. Rioting Londoners fear that the European foreigners' strange dietary habits would do harm on English food, the English body and English economy. In Coriolanus starvation is the primary trigger for the enmity between the senators and citizens. Menenius employs the fable of the belly to quell the hungry citizens' anger and to emphasize the senators' role as a store of nutrition to feed the body, that is, the citizens. Coriolanus' contempt for the body's need comes to a devastating end. In Pericles the famine is brought about by the gluttonous consumption of specific foods. The problem of greedy consumption becomes that of living in the cannibalistic situation where mothers are willing to eat their children and married couples one another. Pericles feeds the hungry people with bread, and is also saved from starvation by the fishermen after shipwreck. In this way the three plays provide the examples of Shakespeare's notion on healthy food and feeding.

Food sovereignty is the right of peoples to healthy and culturally appropriate food produced through ecologically sound and sustainable methods, and their right to define their own food and agriculture systems. An increase in the price of food that occurs as a result of increased demand from human consumption and use as an alternative energy resource. Furthermore, agflation, a combination of the words "agriculture" and "inflation", will also affect non-vegetative foods as the price increases for grain will make livestock feed more expensive as well. Food sovereignty implies new social relations free of oppression and inequality between men and women, peoples, racial groups, social classes and generations.

Livestock products like meat, milk and egg have been principal food sources for human beings since the historic periods of time. Nowadays consumption of these food items have been avoided due to its high contents of SFA, cholesterol and total fat which are major culprits of chronic adult diseases causing major deaths of people. However, the relationship between livestock products and diseases is not always true because the amounts of fat and cholesterol and types of fatty acids in meat and meat by-products depend on the part of the meat and types of animals. Although meat intakes do not always cause mai or adult diseases, still the developmental necessity does exist for animal foods equipped with biologically active properties, which in turn can improve nutritional status and health more than ever Meat with high protein lean part and low fat can be produced by applying synthetic somatotropin and beta-adrenergic agonists like clenbuterol, cimaterol etc. during breeding. This application brings benefits like higher growth rate, lower fat contents and improve feed efficiency ratios. Meats fortified with long chain PUFA($\omega$-3 fatty acids) can also be produced by modulating feed composition.Egg Products have faced the reduced sales annually because of its high cholesterol contents. Recently brand eggs fortified with special nutrients or chemical components having functional proper ties in the human body system are very popular Research Interests have been focused on eggs with low cholesterol and high omega-3 fatty acids. Low cholesterol eggs and high omega-3 eggs can be produced in several different ways, but popular way to increase is feeding the feeds with different oil sources containing high omega-3 and 6 fatty acids such as fish oil, perilla oil, linseed oil and lecithin etc. But proper compositon of feed formula should be found and economically beneficial. Brand eggs fortified with vitamin, mineral, unknown growth factors are also manufactured. Low cholesterol and high $\omega$-3 PUFA milk are marketed recently Cholesterol removal technology is not completely established and has several limitations to be overcome. Milk fortified with $\omega$-3 fatty acids is made by incorporating high &13 fatty acid foods in feed despite of extraordinary way of fatty acid metabolism In cow. All these biologically active products will be very beneficial and useful for human consumption when limitations of manufacturing technology such as safety and lowered sensory qualities are resolved. Furthermore, thorough and precise tests and quality control for these products should be performed to ensure the effectiveness and usefulness in terms of improving health and nutritional status in general. However one caution should be pointed out to lay people informing that these items are nothing but a food and not panacea. Therefore, it is important to remember that the only way of maintaining good health is absolutely through consuming balanced diet.

This paper proposes an architecture of $3^{rd}$ order SDM(Sigma-Delta Modulator) with delayed feed-forward path in order to reduce the power consumption and area. The proposed SDM improve the architecture of conventional $3^{rd}$ order SDM which consists of two integrators. The proposed architecture can increase the coefficient values of first stage doubly by inserting the delayed feed-forward path. Accordingly, compared with the conventional architecture, the capacitor value($C_I$) of first integrator is reduced by half. Thus, because the load capacitance of first integrator became the half of original value, the output current of first op-amp is reduced as 51% and the capacitance area of first integrator is reduced as 48%. Therefore, the proposed method can optimize the power and the area. The proposed architecture in this paper is simulated under conditions which are supply voltage of 1.8V, input signal 1Vpp/1KHz, signal bandwidth of 24KHz and sampling frequency of 2.8224MHz in the 0.18um CMOS process. The simulation results are SNR(Signal to Noise Ratio) of 88.9dB and ENOB(Effective Number of Bits) of 14-bits. The total power consumption of the proposed SDM is $180{\mu}W$.
