Alcohol exposure during development leads to significant long-term neurobehavior dysfunction and central nervous system alteration. The purpose of this study was to determine the effects of enriched enviroment in developmental period through motor behavior test and expression of BDNF. Neonatal rat exposed to alcohol on postnatal days 4 through 10 were studied. Female Sprague-Dawley pups were assigned to two groups. Experimental group(EG) via 4.5 g kg-1day-1 of ethanol was housed in enriched enviornment for 9 weeks. The main result of this study were as follows: 1. There was significant difference in the mean of weight change between control and experimental group. 2. In motor behavior test, there was significant difference in the mean of weight change between control and experimental group. 3. Regarding the immunoreactivity of BDNF were higher appeared experimental group than control group. In conclusion, the present results reveals that enriched enviroment in developmental period is to be extremely useful in neuronal reprganization and motor behavior improvement after alcohol exposure.

Cim realization for the machinery manufacturing plant has several problems such as a lack of the adaptibity for system integration of the production machines, a lack of the flexibility for the information flow and a lack of the interchangeability fot the variety of the interchange information. In the paper the development of VMD for the object oriented machine tool in Cim enviroment is accomplised. FOr this purpose VMD is constructed in PC with NT 3.51/OS enviroment by using the exculsive comunication board and PLC for the conventional CNC machine tool that VMD support is not available. And also RS232 interface between VMD and CNC's and DNC 2 comunication board supplied by FANUC for two types of CNC are used. This developed VMD is very useful for CIM construction in the shop floor having the multi-vendor CNC controllers.

This article described the production problems, import conditions of organic livestock products and background of CODEX-guideline, and presented the counterplan for future organic livestock production policy. The essential counterplan for CODEX-guideline and construction of organic livestock production basis include ; - Specific funding of research and development for excellent livestock breeding with consideration of regional enviroment-friendly applications to improve the quality of organic livestock products, - Development of production potential and resources utilization of organic feeding stuffs in domestic and foreign countries, - Horizontal and vertical organization of organic livestock farming and multifarm cooperation, - Specialization of organic livestock farming, and construction for direct or indirect linkage markets and Agro-food corporation for closer cooperation between inner and outer factor of farm management, - Construction of recycling system for the enviroment-friendly utilization of animal excrements.
