This study was conducted 1) to compare the nutrient content and mineral composition of the Philoppine indigenous sheep and goats diets when grazed in common pasture during rainy season, 2) to determine the influence of sampling methods on nutrient content and mineral composition of upland (UP) and lowland (LP) native pastures, and 3) to compare these two pasture types in terms of nutrient and mineral composition. Experiment 1 used sis esophageally fistulated animals, three each for sheep and goats. Weekly extrusa collection was done for a period of three months. Experiment 2 was conducted in UP and LP; these were sampled thrice by three methods, plucking, clipping and use of three esophageally fistulated sheep. Results of Experiment 1 indicated that the diets of sheep were greater in crude protein(CP; p < 0.01) and ether extract(EE; p < 0.05) but lower in crude fiber (CF) and acid detergent lignin (ADL; p < 0.05) than that of goat diets. All other nutrient fractions including mineral composition were not significantly different from each other. Significant findings of Experiment 2 were: CP content of UP was in the order fistulated > plucked > clipped (p < 0.05); CP content of LP was greater (p <0 .05) in fistulated and plucked samples; and ash content was greater (p < 0.05) in fistulated samples of both pastures. The CP of UP was different (p < 0.05) from each sampling method but the CP of LP and ADL of both pastures were greater (p < 0.05) in clipped samples. Most minerals either macro or microminerals were greater in fistulated samples of both pastures. Pooled data of the two pastures showed that LP had better nutrient characteristics and greater mineral composition. Based from this study, there were few differences between the diets of indigenous sheep and goats when grazed in common pasture. Also, sampling methods influenced the nutrient composition of indigenous sheep diets.

Tannery waste contained 90.93% DM, 77.02% CP, 0.77% CF, 2.83% EE, 7.19% ash and 3,450 kcal ME/kg DM. A total of 144 day-old broiler chicks were divided into three dietary groups; $D_1$ (Containing 10% protein concentrate-PC), $D_2$ (Containing 5% PC+5% tannery waste-TW) and $D_3$ (Containing 10% TW) having 3 replicates of 16 chicks in each. The birds were fed broiler starter diet containing 22% CP, 3,000 kcal ME/kg and broiler finisher diet containing 21% CP, 3,100 kcal ME/kg up to 42 days of age, and meat yield traits were measured from the representative birds from each replication to asses the feasibility of using tannery waste in the diet of broiler. Feed intake, live weight, feed conversion efficiency and livability did not differ between diets (p>0.05) but the cost of production and profitability differed significantly (p<0.001). Profitability of D1, D2, and D3 diets were 2.98, 9.90 and 14.04 Taka/kg respectively. Diets did not affect on meat yield traits (p>0.05), except gizzard, shank and feather weight (p<0.01). Gizzard and shank weigh were improved with increasing level of tannery wastes in the diet, hence tannery waste can be used without any harmful effect in the broiler diet.

Background: Chronic obstructive pulmonary disease (COPD) is an important cause of occupational mortality in miners exposed to coal mine dust. Although the inflammatory mediators involved in COPD have not been defined, many studies have shown that inflammatory mediators such as reactive oxygen and nitrogen species are involved in orchestrating the complex inflammatory process in COPD. Methods: To investigate the relevance of exhaled biomarkers of oxidative and nitrosative stress in participants with COPD, we determined the levels of hydrogen peroxide, malondialdehyde (MDA), and 3-nitrotyrosine (3-NT) in exhaled breath condensate (EBC) in 90 retired elderly coal miners (53 non-COPD and 37 COPD participants). Results: Mean levels of MDA (4.64 nMvs. 6.46 nM, p = 0.005) and 3-NT (3.51 nMvs. 5.50 nM, p = 0.039) in EBC were significantly higher in participants with COPD. The median level of MDA did show statistical difference among the COPD severities (p = 0.017), and the area under the receiver operating characteristic curve forMDA (0.67) for the diagnostic discrimination of COPD indicated the biomarker. The optimal cutoff values were 5.34 nM (64.9% sensitivity and 64.2% specificity) and 5.58 nM (62.2% sensitivity and 62.3% specificity) forMDA and 3-NT, respectively. The results suggest that high levels ofMDA and 3-NT in EBC are associated with COPD in retired elderly miners. Conclusion: These results showed that the elevated levels of EBC MDA and EBC 3-NT in individuals with COPD are biomarkers of oxidative or nitrosative stress.

While .NET and J2EE bisects recent distributed environment, .NET displays "Remoting" as a technology to call remote object. Remoting is frequently used as a protocol in OLTP's WEB program development in form of RPC that exchange data in XML form under HTTP environment. Purpose of this research is to draw problems when applying security to .NET remoting technology that is recently used in web programming, and to find effective application plan by implementing. The main discussion is following. First, network layer security should be replaced to application layer security for better performance and flexibility. Second, the serialization procedure that is repeated in both remoting and encryption module should take place once. Lastly, implementation of "Surrogate" and "Compress" will be discussed that enables to eliminate unnecessary data(table relations, keys, etc) that is used in dataset object of .NET in order to reduce the size of data. It is possible to achieve improvement in speed by two times through immediate implementation in these cases. In order for easier use, component based framework should be supplied hereafter.
Background: Liquid feeding system has been introduced to domestic swine farms, but negative cognition about liquid feeding system has been remained for feed waste decay related with poor management and microbial contamination. For these reasons, this study was conducted to evaluate the effects of feeding method in lactating sows. Methods: A total of 30 mixed-parity (average 4.13) lactating sows (Yorkshire ${\times}$ Landrace) with an initial BW of $218.8{\pm}19.5kg$ was used in a 3 week trial. Sows were allotted to 1 of 2 treatments in a completely randomized design by their body weight, backfat thickness, parity and alive litter weight. One of treatments was dry feeding and the other was liquid feeding (water to feed ratio, 1:1). Experimental diets contained 3265 kcal ME/kg, 12.6 % CP, 5.76 % EE, 1.09 % total lysine, 0.25 % total methionine, as fed basis. Results: Dry feeding treatment had high body weight loss rather than liquid feeding treatment (P = 0.04). Dry feeding treatment had tendency to increase litter weight at 21d of lactation (P = 0.06) and litter weight gain (P = 0.04) during lactation period (0-3 week). Sows fed dry feeding method made milk containing high content of casein and total solid rather than sows fed liquid feeding method (P = 0.04). In addition, dry feeding treatment had tendency to higher content of milk fat, protein and solid not fat on 21d of lactation (P = 0.07). Sows fed dry feeding type also showed higher milk energy content in milk of 21d lactation (P = 0.05). Furthermore, liquid feeding treatment showed high occurrence in feed waste during lactation period (P <0.01). Conclusion: Dry feeding method was more suitable feeding method to lactating sows under high temperature environment like lactating barn.
Oriental medicine statistics are essential in research planning, research evaluation, and policy decision based on objective data. However, integrated administration of such statistics is not presently possible in the oriental medicine field, which has been slow in incorporating information communication technology. In an effort to address this problem, the Korea Institute of Oriental Medicine (KIOM) developed an oriental medicine statistical system in 2009, and the system has been offered in the traditional medicine information portal of OASIS. However, according to a 2010 survey targeting OASIS users, those surveys reported that needs for a system where various statistical data can be extracted via an interactive approach to multidimensional data. As a result of an analysis of the functions of the existing system, it was found that it is necessary to array and arithmetically analyze Stats Value, Drill Up & Drill Down, and Pivot. To this end, the existing DB schema should be redesigned. Based on our analysis result, we redesigned the database into a structure that is applicable to the reverse pivot algorithm. We used J2EE/JSP and a Flex framework to design and develop an oriental medicine statistical system that can provide multidimensional statistical data. Considering that the improved oriental medicine statistical system is planned to be offered by OASIS of KIOM, utilization and value of oriental medicine statistical data are expected to be enhanced.
Three trials were conducted to study the effect of processing method on performance, apparent nutrient and amino acid digestibilities in growing-finishing pigs fed lupine seeds. Ground, expanded or flaked lupine seed was prepared for the trials. In trial 1, a total of 72 growing barrows ($Landrace{\times}Large$$White{\times}Large$, initial BW of $54.22{\pm}5.87$ kg) were allocated to three treatment diets containing 15% percent of differently processed lupine seed for 28 days. Each treatment had four replicates comprising 6 pigs each. In trial 2, a total of 48 finishing barrows ($Landrace{\times}Large$$White{\times}Large$, initial BW of $84.40{\pm}6.84$ kg) were subjected to three treatments for 21 days. The experimental design was the same as trial 1 except for supplementation with 20% of lupine seed. Each treatment had four replicates comprising 4 pigs each. To evaluate the ileal digestibility of amino acids, a total of 9 barrows ($Landrace{\times}Large$$White{\times}Large$), with an average initial BW of $41.07{\pm}1.98$ kg, were fed with ground, expanded or flaked lupine for 7 days. Each pig was surgically equipped with a simple T-cannula fitted in the distal ileum. Amino acid composition and presence of anti-nutritional factors (ANFs) in processed lupine sources were also evaluated. The results showed that there was no significant difference (p>0.05) in lupine amino acid composition due to the different processing methods. Expanded and flaked lupine significantly decreased (p<0.05) the concentration of ANFs compared with ground lupine. There was no effect (p>0.05) on the growth performance in growing pigs. However, processing method had a significant effect (p<0.05) on average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) in finishing pigs. There was no effect (p>0.05) of the different processing methods on the digestibility of dry matter (DM), gross energy (GE), ether extract (EE), Calcium (Ca) and phosphorus (P), but expanded lupine could significantly increase (p<0.05) the apparent digestibility of CP in finishing pigs. Furthermore, expanded lupine had a higher (p<0.05) apparent ileal digestibility for most indispensable and dispensable amino acids compared with ground and flaked lupine. It was concluded that expanded lupine could be beneficial in improving lupine's quality and improve performance and nutrient utilization in growing-finishing pigs.

Top synthetic spin valves with structure Ta/NiFe/CoFe/Cu/CoFe(P 1)/Ru/CoFe(P2)/FeMn/Ta on Si (100) substrate with natural oxide were prepared by dc magnetron sputtering system. We have changed only the thickness in free layers and the thickness difference (Pl-P2) in two ferromagnetic layers separated by Ru, and investigated the effect of magnetic film thickness on interlayer coupling field in spin valve with synthetic antiferromagnet. According to the decrease of free layer thickness, interlayer coupling field was increased due to the magnetostatic coupling(orange peel coupling). In case of t$\_$P1/>t$\^$P2/, interlayer coupling field agreed well with the modified Neel model suggested in conventional spin valve structures by Kools et al. However, in case of t$\_$P1/>t$\^$P2/, it was found that the interlayer coupling field was not explained by the Modified Neel Model and was confirmed the necessity of further remodeling. The dependence of Cu thickness on the interlayer coupling field was investigated and 10 Oe of interlayer coupling field was obtained when the Cu thickness is 32 $\AA$.
Effects of B addition and heat treatment on the magnetic and magnetostrictive properties of amorphous SmFe$_2$ thin films are investigated. A significant improvement in the magnetostrictive properties at low magnetic fields is observed with the addition of B. This improvement, however, is achieved at a heavy cost of intrinsic properties such as saturation magnetostriction. For example, at a magnetic field of 30 Oe, magnetostriction of a thin film with a B content of 9.9 at.% is increased from 190 to 333 ppm, but saturation magnetostriction is decreased by more than 50 %. This result is in accord with the deterioration (reduction) of saturation magnetization and the improvement (reduction) of coercive force at this B content. The magnetostrictive properties are also improved by annealing and optimum annealing temperature is found to be in the range 300-400 $^{\circ}C$. The main reason for the improvement is mainly considered to be due to the reduction of coercive force caused by stress relief, not due to the ultrafine SmFe$_2$ precipitates which were originally expected to form by annealing.
The experiment was conducted for a period of 56 days with twelve Bangladeshi bull calves of average body weight of $127.20{\pm}11.34$ kg. The calves were divided into 3 groups having 4 animals in each. The animals were fed urea-treated rice straw designated as A) 4% urea-treated rice straw, B) 4% urea+4% soybean-treated rice straw and C) 4% urea+6% soybean-treated rice straw. In addition, all the animals were supplied 2 kg green grass, 350 g Til-oil-cake and 100 g common salt per 100 kg body weight of animals. Straw was treated with 4% urea solution and soybean meal at 4 and 6% were added to treated straw and kept for 48 h in double layer polythene bags under anaerobic condition. Urea treatment improved crude protein (CP) content of rice straw from 2.68 to 8.70% and it was further increased by 10.74 and 12.12% with the addition of 4 and 6% soybean meal. Dry matter (DM) intake (kg) was higher (p<0.05) in C (4.2) followed by B (4.1) and A (4.0). Crude protein intake was significantly higher (p<0.05) in group B and C than group A. Total live weight gains were 20.2, 24.8 and 25.6 kg for calves of group A, B and C respectively (p<0.01). The addition of soybean meal to treated rice straw did not affect the coefficients of digestibility of DM, OM, EE and NFE. However, CP and CF digestibility were significantly higher in group B and C (p<0.05). The values for digestible crude protein (DCP), digestible ether extract (DEE), digestible nitrogen free extract (DNFE) and total digestible nutrients (TDN) were significantly (p<0.05) higher in diet C and B in comparison to diet A, but there were no significant difference in digestible organic matter (DOM) and digestible crude fibre (DCF) value among the groups. It may be concluded that 4% urea treated rice straw can be fed to growing bull calves with 2 kg green grass and a small quantity of concentrate without any adverse effect on feed intake and growth. Moreover, soybean meal at 4 and 6% can be added to urea treated rice straw at the time of treatment for rapid hydrolyzing of urea, which resulted an improvement in nutrient digestibility and better utilization of rice straw for growth of growing bull calves.
