The recent surge in live streaming has also changed the market for classical performing arts. Now more than just recording live performances, content specific to live streaming platforms is being produced, and live streaming is emerging as a new alternative to promoting and enjoying classical performances. Therefore, this study empirically analyzed the effect of service quality factors of the classical live streaming performance on the viewer satisfaction and the purchase intention of the on-site performance over the data collected from 198 viewers. Results suggest that, among the service quality factors of the classic live streaming performance, video content, convenience, and price, except for real-time interaction, affected the viewer satisfaction, and viewer satisfaction in turn affected the purchase intention of the on-site performance. Thus the publicity effect of live streaming for classical performing arts seemed to be proved.

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.

In this Paper, We proposed the HLS(Http Live Streaming) transmitter which is operated easily and cheap in all networks and client environments compared to the exist video live streaming transmitter. We analyzed the HLS protocol and then implemented for making the HLS transmitter cheaper and portable. After designing the HLS transmitter hardware using the RISC processor of Arm11 core, we ported the Linux Operating System and implemented the HLS protocol using the open source FFmpeg and Segmenter. For the performance evaluation of the developed HLS transmitter, we made the testing environment which is including the notebook, iPhone, and aroid Phone. In this testing environment, we analysed the received video data at the client displayer. As a results of the performance evaluation, we could certify that the proposed HLS transmitter has a higher performance than the Apple company's HLS.

In order to attain heavier live weight without impairing pork or sensory quality characteristics, carcass performance, muscle fiber, pork quality, and sensory quality characteristics were compared among the heavy weight (HW, average live weight of 130.5 kg), medium weight (MW, average weight of 111.1 kg), and light weight (LW, average weight of 96.3 kg) pigs at time of slaughter. The loin eye area was 1.47 times greater in the HW group compared to the LW group (64.0 and 43.5 cm², p<0.001), while carcass percent was similar between the HW and MW groups (p>0.05). This greater performance by the HW group compared to the LW group can be explained by a greater total number (1,436 vs. 1,188, ×10³, p<0.001) and larger area (4,452 vs. 3,716 μm², p<0.001) of muscle fibers. No significant differences were observed in muscle pH_{45 min}, lightness, drip loss, and shear force among the groups (p>0.05), and higher live weights did not influence sensory quality attributes, including tenderness, juiciness, and flavor. Therefore, these findings indicate that increased live weights in this study did not influence the technological and sensory quality characteristics. Moreover, muscles with a higher number of medium or large size fibers tend to exhibit good carcass performance without impairing meat and sensory quality characteristics.

This paper researches the algorithm, whose materiality and expressiveness can be obtained through live coding. Live coding is an improvised genre of music that generates sounds while writing code in real time and projecting it onto a screen. Previous studies of live coding have focused on the development environment to support live coding performance effectively. However, this study examines the aesthetic attitude immanent in the realization of the algorithm through analyzing mostly used languages such as ChucK, Impromtu, and the visualization of live code and cases of "aa-cell" and "slub" performance. The aesthetic attitudes of live coding performance can be divided into algebraic and geometric attitudes. Algebraic attitudes underline the temporal development of concepts; geometric attitudes highlight the materialization of the spatial structure of concepts through image schemas. Such a difference echoes the tension between conception and materiality, which appears in both conceptual and concrete poetry. The linguistic question of whether conception or materiality is more greatly emphasized defines the expressiveness of the algorithm.

The influence of supplementing diets with various levels of organic zinc (OZ) on the performance, meat quality attributes, and sensory properties of broiler chickens was investigated. A total of 3,200 1-d-old female broiler chicks were randomly allotted to 16 floor pens (replicates) with 200 birds per pen. A corn-wheat-soybean meal basal diet (control) was formulated and 20 ppm OZ (20 OZ), 40 ppm OZ (40 OZ), or 80 ppm OZ (80 OZ) was added to the basal diet to form four dietary treatments with four replicates per treatment. Live performance of broiler chickens, meat quality, and sensory properties were evaluated. The results showed no significant difference among the treatments for live performance of broiler chickens. Significant increases (p<0.05) in thigh skin epidermis and dermis thickness were shown in the OZ supplementation groups; however, no effect of OZ on the thickness of back skin epidermis or dermis was found. Dietary OZ levels did not affect the pH of breast and thigh meat or the water holding capacity (WHC) of thigh meat, but the WHC of breast meat increased significantly (p<0.05) when birds were fed 40 OZ and 80 OZ. Results of a sensory analysis showed no differences among the dietary treatments. In conclusion, dietary OZ did not affect live performance or sensory properties of broiler chickens but did increase the WHC of breast meat and thickness of skin layers; thus, improving carcass quality in broiler chickens.

Precision Guided Missiles after production and militarization have various characteristics that enable the final performance to be identified by conducting live-fire tests after long-term storage. Likewise, the performance and reliability of ${\bigcirc}{\bigcirc}$ Missiles, which are currently used by the Korean Navy, are also verified consistently by conducting live-fire tests after militarization. Specially, the live fire test at '00 year, which was conducted by Korean Navy, showed the result that 'Ring', which is a component of the canister's front cover, was jammed with wings for propulsion and then broke away from the canister during the missile launch process. This situation led to an interruption of the deployment of wings and finally affected the missile's flight performance. The results of a survey of the canisters of those missiles whose live fire tests were conducted successfully, based on the live fire test at '00 year, showed the 'Ring's separation from canisters. This raises recognition for the need to solve the problems of 'Ring's separation and breakaway. This study suggests an improvement derived by the result of live-fire tests and introduces the effect of final launch performance of ${\bigcirc}{\bigcirc}$ Missiles and test result after applying the improvement.

The multi-span suspension bridge having double main cables in the vertical plane is investigated regarding endurance of live load distribution in the case of non-displaced pylon and pylon displacement. The coefficient formula of live load distribution described as the ratio of live load on the bottom cable to the top cable is obtained. Based on this formula, some function in respect of this bridge are derived and used to analyze its characteristics. This analysis targets the cable force, the cable sag and the horizontal displacement at the pylon top under live load etc. The results clarified that the performance of the live load distribution and the horizontal force of cables in the case of non-deformed pylon has a similar tendency to those in the case of deformed pylon, and the increase of pylon rigidity can increase live load distributed to the bottom cable and slightly raise the cable horizontal force under live load. However, effect on the vertical rigidity of bridge and the horizontal force increment of cables caused by live load is different in the case of non-deformed pylon and deformed pylon.
