The new characteristic of Millennial High-Tech Media is breaking the existing standardized creative grammar. The destructive form of high-tech media is differently accommodated according to the consumer's tendency or characteristics. The purpose of this study is to explore guidelines for effective creative strategy creation of high-tech media. In consumer psychology, consumer innovation is a key factor in evaluating the creativeness of high-tech media. The results of finding out the effect of persuasive communication on consumer innovation and advertising creative type are as follows. Informative(image) creative type showed higher attitude toward advertisement, brand attitude, purchase intention, and prior intention to consumers with high innovation than consumers with low innovation.

Since concentration of greenhouse gas increases continuously from human's fossil fuel use, urbanization, and cultivation, it is trend that climate change is appearing. In Addition, in 20th century, occurrence of disaster is accidental and huge, and damage level also increases gradually. Therefore, in order to preserve the territory and to protect people's life and property against new type disasters, disaster detection satellite (payloads) development is required urgently. In this paper, we conduct a research and development for the prompt preemptive action when occurred a disaster, in particularly, about the disaster observation optimized at Korea's geographical features for the irregular future disasters. For the payload design which is specialized detect disasters, we create a tech tree of satellite imagery applications based 10 disaster types, and analyze the satellite sensor technologies referred to Landsat-8, Worldview-3 and ALOS-2.

A cross drilling/milling Unit is an important mechanical part which is widely used in many kinds of machining tool, and various gear trains with good accuracy and reliability features are widely used in power transmission systems. A study on a novel power transmission optimization method for driving gear trains in cross drilling/milling units is presented in this paper. A commercial program for gear system simulation, Romax Designer, was used in this research to intuitively observe the gear meshing and the load distribution conditions on the gear teeth. We obtained the optimal modification value through comparing the results of repeated experiments. For validation, optimized gears were fabricated and then measured with a precision tester.
