The early day of manufacturing automation systems are NC machine tool Based automation, and now it become FA, DNC, FMC, FMS, CIM and IMS. Manufacturing Automation Technology is applied the increase of all industrial manufacturing competitve power. so the demand of this skill is repidly increase. This Technology can solve lack of manpower, decrease of productivity, and become weakened international competitive. But, automation rate of our country is 30-40%, because the level of domestic technology is low, so we need systemic research of manufacturing automation. The targets of this study are increase the data processing ability of CNC controller, and development of autonomous manufacturing system that can decision making between production module such as setup, manufacturing, inspection and transportation and part that object of manufacturing.

Breast cancer is growing rapidly year by year and has the highest incidence since 2001. As a result, the interest in mammography for early detection of breast cancer is increasing. However, mammography is accompanied by radiation exposure and therefore it is necessary to reduce exposure dose through appropriate test conditions. The significance of this study is that breast dose studies, which were limited to ordinary women, were applied to breast implant patient. Using MCNP simulation, the phantom with prosthesis inserted was developed to compare dose by tube voltage by pressure thickness. In addition phantom without prostheses has higher dose than phantom with prostheses. If these results were used as basic data, it would be possible to recommend test condition guideline only for breast implant patients.

In Korea, antibiotics have been widely used to prevent diseases and to enhance the growth of animals. Recently, it is reported that residual antibiotics in the environment caused harmful effects by producing antibiotic resistant bacteria (ARG) in the surrounding ecosystem. Thus, researchers started to monitor the occurrence, fate and transport of human and veterinary antibiotics in the environment. The objective of this article is to evaluate state-of-art technology to remove residual antibiotics in soil and water ecosystem based on recent published articles. We put focus on antibiotics degradation by adopting composting, anaerobic digestion, adsorption and phytoremediation technology. Although there is no regulation regarding treatment of wastes with antibiotics, continued research on this topic should be pursued.
