This experiment was conducted to investigate the effects of different fat source feeding on growth performance, visceral organ weight, meat color, excreta microflora and blood profiles in broilers. A total of 768 1-d-old ROSS 308 broilers (mixed gender) with an initial average body weight of 39.68 ± 0.14 g were randomly allotted to 4 treatments with 12 replicate pens per treatment and 16 broilers per pen for 32 days. Dietary treatments were: 1) SBO, basal diet + 5% soybean oil, 2) PF, basal diet + 5% poultry fat, 3) TAL, basal diet + 5% tallow, and 4) LARD, basal diet + 5% lard. During d 1 to 14, broilers fed TAL diet had a higher (P<0.05) body weight gain (BWG) than broilers fed with PF and LARD diets, moreover, broilers fed TAL diet had a higher (P<0.05) feed intake than broilers fed SBO, PF and LARD diets. Overall (d 0-32), BWG in SBO and TAL treatments was greater (P<0.05) than that in LARD treatment. The meat color a<sup>*</sup> (redness) of broilers fed with LARD diet was increased (P<0.05) compared with broilers fed with PF and TAL diets. No difference was observed in visceral organ weight of liver, spleen, bursa of Fabricius, breast muscle, abdominal fat, gizzard and excreta concentrations of Lactobacillus and Escherichia coli. The blood LDL cholesterol concentration in TAL treatment was higher (P<0.05) than that in LARD treatment. In conclusion, broilers supplementation with tallow could improve not only the body weight gain and feed intake but also blood LDL cholesterol concentration. Moreover, broiler fed lard could increase a<sup>*</sup> (radness) of meat color, while the soybean oil supplementation improve body weight gain in broilers.

Offspring of 14 sows were used to evaluate the effect of yogurt substituted for creep feed on growth performance, diarrhea score and blood profiles. The piglets of sows were randomly allocated into 1 of 2 treatments (1 treatment separated piglets of 7 sows). The dietary treatments were as followed: CF, creep feed; YG, yogurt. The creep feed and yogurt diets were given from 3 d after piglets were born to the day of weaning (21 d after piglets were born). The body weight and feed consumption were weighed and recorded at d 0, 7, 14, and 21 after piglets were born for calculating average daily gain (ADG) and average daily feed intake (ADFI). At the weaning day, two piglets were randomly chosen from each pen and bled via jugular venipuncture to obtain blood samples for WBC and IgG measurement. All data were subjected to the GLM procedures of SAS (2002) as a randomized complete block design, with pen as the experimental unit. Differences among dietary treatments were separated by Duncan's multiple range test, and P < 0.05 was considered statistically significant. No significant difference (P > 0.05) were observed in number of born piglets, weaning pigs, survival rate, body weight of piglets at d 0, 7, 14, and 21, ADG and ADFI. At d 21, piglets fed with creep feed had a higher (P < 0.05) IgG compared with piglets fed with yogurt. No significant difference (P > 0.05) was observed in WBC among treatments at d 21. In conclusion, yogurt substituted for creep feed had no adverse effect on growth performance in lactating piglets.

A study has been conducted experimentally on the natural convection heat transfer characteristics of fin arrays on a horizontal flat plate in air. The effects of fin heights and Rayleigh numbers are mainly investigated.<br/> The experimental results are as follows;<br/> 1. The mean fin and mean total Nusselt numbers increase as dimensionless fin heights increase at 0.67≤H/S≤1.67. The mean plate Nusselt numbers increase in case of upward facing fins, but they decrease in case of downward facing fins. <br/> 2. The mean Nusselt numbers increase as Rayleigh numbers increase. 3. The mean fin surface Nusselt numbers has its maximum outside surface (Y₁) where there is no interference from each other fin.<br/> 4. The mean total Nusselt numbers in case of upward facing fins increase by 47% and 26%, respectively at H/S = 0.67 and 1.67 than those in case of downward facing fins for Ra_s = 6.50 X 10³.<br/>

In this paper, we present the development procedure of fully implantable hearing device with round window driving method which is named ACROSS-RW. The system consists of an implantable microphone, a signal processing body, and a vibration transducer. Each component is developed with needs of hearing losses and novel idea for overcoming lacks of previous studies. The performance of the system is evaluated from public certification organization and mechanical engineering laboratory of Stanford University in USA, which is well-known for testing of active middle ear implants. ACROSS-RW can provide natural sound and good cosmetic to people who suffer from hearing loss.

A conjugate conduction-convection analysis has been made for a plate fin which exchanges heat with its fluid environment by forced convection. The analysis is based on a one-dimensional model for the plate fin whereby the transient heat conduction equation for the fin is solved simultaneously with the conservation equations for mass, momentum, and energy in the fluid boundary layer adjacent to the fin.<br/> The forced convection heat transfer coefficient is not specified in advance but is one of the results of the numerical solutions. Numerical results of the overall heat transfer rate, the local heat transfer coefficient, the local heat flux, the fm efficiency and the fin surface temperature distribution for Pr=O.7 are presented for a wide range of operating conditons.

<br/> The intake system of 4-cycle, 4-cylinder reciprocating engine is investigated the simple model composed of vessel, duct and throttling part. The numerical calculation based on the simulation is performed for the flow phenomena including heat transfer, friction and bend of duct at each part. In the multi-cylinder engine, the volumetric efficiency is increased a little as the junction location is closed to cylinder at the engine speed having maximum volumetric efficiency. The confIguration and dimension of intake system have an influence on the inertia effect by resistance and pressure variation, and the magnitude of that is varied by the engine speed. Thus the volumetric efficiency is correlative to them. The volumetric efficiency is high as the intake valve close is advanced at the low engine speed, and is delayed at high speed.

The problem of laminar mixed convection flowing over a vertical plate fin is analytically studied by onjugate convection-conduction theory. The analysis is based on a first principles approach whereby the heat conduction equation for the fin is solved simultaneously with the conservation equations for mass, momentum and energy in the fluid boundary layer adjacent to the fin. Numerical results are given for various quantities of interest including the local heat transfer coefficient, local heat flux, fin efficiency and temperature distributions of fm under the effects (if Prandtl number, the buoyancy parameter and the convection-conduction parameter. The results of the present numerical solution have been compared with those of the conventional fin theory. It is found that there are some discrepancies in the fin efficiency and the temperature distribution between present method and the conventional fin theory.
