Air Traffic Control is a job that aptitude is strongly needed. According to this, air traffic controllers have to be chosen and arranged by their duty characteristic. With the development of aviation industry, we need more capable air traffic controllers than before. However, it is true that there is no aptitude test for them in Korea. The world wide trend for air traffic control is changing that decision making and high ability with awareness for solving problem. Therefore the aptitude test is certainly required in order to select suitable people having basic abilities for the duty. This research inquires into the aptitude test which is globally taken because of the reason. And with result of that, inspection list is made for development of a tool for aptitude test which is suitable in Korea and additionally there are some special opinions of experts about the list. It is judged that this research will be based for the development of aptitude test in order to select air traffic controller.

This paper describes atmospheric phenomena and effects for satellite-to-ground laser communication channel. Satellite laser communication has advantages such as very high bandwidth, inherent security, robustness to electromagnetic interference, unlicensed frequency band. However, satellite laser communication is affected by various factors. Transmission quality is degraded by factors as system loss, geometric loss, misalignment loss, atmospheric loss. Atmospheric loss is major factor of performance degradation. In this paper, the atmospheric phenomena such as absorption, scattering and turbulence are discussed and analyzed for developing satellite laser channel model and laser transmission scheme robust to atmospheric phenomena.

The neural network with radial basis function is introduced for position tracking control of AC servo drive with the existence of system uncertainties. An adaptive robust term is applied to overcome the external disturbances. The proposed controller is implemented on a high performance digital signal processing DSP TMS320C6713-300. The stability and the convergence of the system are proved by Lyapunov theory. The validity and robustness of the controller are verified through simulation and experimental results

Danger to export-oriented East Asia and Latin America lurked closer in the form of “global imbalances.” East Asia and Latin America are at crossroads in global financial crisis. The common experiences of serious global imbalances and the financial and real sector challenges from imminent rebalancing let them reflect on their macroeconomic soundness and new trade trend between the two regions. Despite the dynamism of interregional trade in recent years, intra-industrial trade pattern has not evolved much throughout the past 20 years, which implies the level of integration between the two regions. There are several policy initiatives to accelerate the institutionalization of trade interdependency in the form of FTAs, but financial and monetary sector cooperation has ended up as symbolic and rhetoric stage by far, or falls short of rigorous development with intensive attention.

As environmental regulations have been tightened around the world, domestic and foreign automobile industries are increasing the proportion of hydrogen and electric automotive components using lightweight materials to reduce exhaust gas emissions and improve fuel efficiency. In particular, hot-stamped boron steel is being used as an alter- native material for frame weight reduction due to thickness reduction, excellent workability, and good elongation. However, surface coating is essential to prevent surface decarburization phenomena and oxidation scale formation between hot stamping processes of boron steel. The coating layer causes many problems in the weldability such as a narrow weldable current range and deterioration of mechanical properties during resistance welding. Therefore, in this study, we introduce research performed to improve the weldability of Al-Si coated hot-stamped boron steel in terms of the material and process.
