Analysis of R-R interal variability is a useful method of obtaining many information about cardiovascular control mechanisms. Among the many methods of analyzing R-R variability, power spectral analysis(PSA) is said to be the most powerful and acurate tool. Although application of computer techniques in analysing R-R interval variability were introduced, as most of the studies on the R-R interval variability have been off-line and invasively, they were not suitable for practical use. So we prepared a program for non-invasive on-line perioperative assessment of R-R interval variability. We used Turbo C++(ver 1.0, Borland International, USA) and Turbo Assembler(ver 2.0, Borland International, USA) for programing. Data were collected by A/D converter(PCL 718,, Taiwan) by interrupt mode and transferred to TBM386 compatibie computer with VGA color monitor. By applying PSA to R-R interval variation, we can get an almost as confident information about the cardiovascular system as analysis of arterial waveform, In addition to this we can get data that requires very reduced momory size, and get them non-invasively. So analysing R- R interval variability may be the most suitable method for on-line continuous assessment of cardiac parameters.

8.Immune support from mother to infant
Journal of Medical and Pharmaceutical Information 2003;0(4):2-6
The child needs time to develop his own immune system and to have specific immune responds. Thus the child needs his mother's support to have immediate protection against bacteria from mother's gastrointestinal tract that infected the baby and have longer protection during his development of immune system. This immune supporting of mother for her baby was conducted thru placenta and breast milk. The immune supporting thru breast milk was directly and indirectly by indirect transmitting of resistance for baby thru breast milk, direct stimulating of baby immune system, and preventing some immune diseases
