In order to investigate the effect of feeding live yeast (Sacckaromyces cerevisiae) on the growth performance and changes of intestinal microorganism (E. coli), a growth assay was conducted with 144 broiler chicks. Treatments were consisted of corn-soybean meal control, 0.05% live yeast, and 0.05% dead yeast. Most of the chick protein of the live yeast was in the pure protein form, and had a high amino acid composition with 47% of essential amino acids and 53% of non-essential amino acids. No differences in growth performance were shown among dietany treatments. Total number of E. coli in the small intestine of chicks fed either live or dead yeast was significantly reduced compared to chicks fed the control diet. Although the changes of E. coli in the cecum were not identical to differences in the small intestine, the changes of E. coli in the cecurn had a similar trend.

The number of students graduating from accredited programs has been increasing annually since the first students graduated from accredited engineering programs in Korean universities in 2004. In this paper, we evaluate the effect of engineering education accreditation by the Accreditation Board for Engineering Education of Korea (ABEEK). We developed performance evaluation indices based on the balanced scorecard concept and applied the proposed indicators to graduates, faculty, and industry employers to see if there are significant differences between accredited and non-accredited groups. Overall, regardless of survey object, engineering education accreditation was perceived to contribute to the elevation of engineering and science and the level of national growth. However, the differences between accredited and non-accredited groups for some key performance indicators were statistically insignificant. The results of this paper are expected to provide crucial feedback information for the improvement of engineering education accreditation in Korea.

Two experiments were conducted to evaluate the performance of broilers and layers fed locally produced fish waste meal (LFWM) in Western Samoa. LFWM, which was produced by mincing and oven drying of rejects from filleted fish, was included in both broiler and layer diets at the complete expense of imported meat and bone meal (MBM). The experiments were of a completely randomised design. In experiment 1, 120 day-old Strabro broiler chicks were raised to 49 days of ages. In experiment 2, 80 Shaver 288 pullets, 20 weeks of age, were housed in pairs in cages and raised up to 72 weeks of age. There were no differences (p > 0.05) in performance of broilers as measured in terms of final bodyweights, feed intake, feed efficiency and carcass yield between the two diets. Similarly, no differences (p > 0.05) existed in egg production, egg weight and feed required per kilogramme of eggs. It is concluded that LFWM is nutritionally as good as imported MBM and could be used to completely replace MBM in broiler and layer diets.

A new combat uniform is improved for added combat safety with various functions such as survivability, battle conformity and a camouflage performance system. Camouflage performance is an important factor in terms of combat survivability since it makes identification difficult and provide security. The combat uniform is worn under extreme conditions (exposure to ultraviolet light, sweat and friction) and an excellent color fastness to repeated washing is required. In this study, we investigated the color management, durability and discoloration of new combat uniform fabric with a digital pattern for camouflage performance to provide preliminary color management data. We examined color differences between standard fabric and mass-produced combat uniform fabrics, color differences between each military supply contract firm and color changes in combat uniforms after 60 washing cycles. The slight color differences between standard fabric and mass-produced combat uniform fabrics were tolerable under quality criteria of Republic of Korea Ministry of National Defense. However, the differences between the military supply contract firms were recognizable to the naked eye and increased with repeated washing. Continuous research on color fastness under repeated washing and color management is required to standardize reliability from each military supply contract firm for the daytime performance of a combat uniform's camouflage.

This study was to examined the effect of chain types exercise of lower limbs on the motor performance differences for the life-carement. For this, twenty normal adult women participated and they were examined the differences of exercise effects about abdominal muscle activity and balance ability by applying two types of chain exercise. In order to identify the differences we let them conduct exercise for 4 weeks with each type of exercise. And we used paired t-test and Independent sample t-test for comparing the differences in the group and inter groups. There was a significant difference in the value of 0.05 to verify statistical significance. As a result of this research, it was found that closed chain exercise is more effective than open chain exercise in muscle activity and balance function. Therefore, in the clinical therapeutic environment, if you apply chain exercise for patient to improve lower limb motor performance, we would recommend the close kinematic chain exercise.
