This study was to investigate the effects of special strength coordination training posture stability and lower segment movements in female sprinters. In order to achieve the purpose of this study, female sprinters at c and k local, were selected at random and allocated 12 female sprinters each for the Non Exercise group(NEG), Deficient Exercise group(DEG), Over Exercise group(OEG) and measured posture stability and lower segment movements before and after the experiment. The special strength coordination training program for 12 weeks. The results of this study were as follows: First, As a result of analyzing the change of posture stability according to special strength coordination training, OEG was significantly improved compared to NEG and DEG. Second, As a result of analyzing the change of lower segment movements according to special strength coordination training, OEG was significantly improved compared to NEG and DEG. As conclusions, this study confirmed that the special strength coordination training on posture stability and lower segment movements in female sprinters. However, there is a need for more specific exercise programs to be developed for the continual improvement of athletic performance in athletics along with further studies to confirm the physiological benefits of those programs.

Magnesium alloys have recently been considered as candidate materials for many automotive components in Europe and North America because of their high specific strength and stiffness with good damping capacity. With the growing environmental reinforcements, the magnesium alloys consumption in automobiles is projected to grow in next decade. Currently, many automobile makers in Europe including Volks Wagen and BMW use magnesium alloys for powertrain components, chassis, and suspension parts. In this paper, the applications of magnesium alloys to automobiles, the prospects of their consumption, and the demand and suppy of magnesium ingots in Europe have been reviewed.<br/>

Metal parts are produced by conventional methods such as casting, forging and cutting, extrusion, etc. However, nowadays, with additive manufacturing (AM), it is possible to directly commercialize by means of stacking of equipment to the 3D drawing and use of high precision tools such as laser source. Thus, drawing of materials is an important aspect in delivering good products. AM deals with production of lighter aircraft parts and few more three-dimensional molds, it wish to manufacture special medical parts and want to steadily expand the new market area. The cost of related equipment and materials are still expensive and difficult to obtain on a mass production. However, the ability to make changes and lead the innovation in the paradigm of traditional manufacturing process is still effective. In this paper, we introduce metal AM and the principles of the related devices, metal powder production process, and their application.

The ubiquitous computing & technology is to make passive IT machinery as the smart-object to solve the problems of information management. These ubiquitous devices can be a concierge of humans lives. In addition, the ubiquitous computing & technology added with Pro-Active processing technology is the intellectual automatic process capacity that probably enhance quality of human`s life. Although the social influencing power of ubiquitous computing technology is so critical, research on the social impact of ubiquitous has been studied insufficiently. And, we also need the countermeasures to protect the societies from the side effect of the ubiquitous computing technology. The purpose of this research is to minimize the loss which comes from the new ubiquitous society, by presenting the technological and systematic alternatives and by researching the various side effects. This research suggests the proper alternatives by reviewing and by researching the adverse effects of the ubiquitous computing technology.

Temperature is a major factor that affects the physiochemical properties of compounds. This study focus on the determination of thermostability and the effect of temperature on antioxidant activities of Ecklonia cava (E. cava) ethanoic extract. The ethanoic extracts of E. cava were evaluated at 30˚C, 60˚C and 90˚C for 0 to 7 days. The antioxidant activities were determined by DPPH, hydroxyl radical and hydrogen peroxide scavenging activities. The intracellular reactive oxygen species (ROS) scavenging activity was investigated using DCFH-DA assay. Results revealed that the ethanoic extract of E. cava incubated at different temperatures for 0 to 7 days, showed stable scavenging activities on DPPH, hydroxyl radical and hydrogen peroxide. The ROS scavenging activities of ethanoic extract and ascorbic acid were also investigated. The extract showed a stable ROS scavenging activity from 0 to 7 day at 90˚C. However, the scavenging activity of ascorbic acid at 90˚C decreased starting from day 3. These results indicated that the antioxidant effects of this food grade ethanoic extract of E. cava could remain stable during the employed temperatures of food processing.
