Recently, the monitoring technology of machining process is very important to improve productivity and quality in manufacturing filed. Such monitoring technology has been performed to measurement using vibration signal, acoustic emission signal and tool dynamometer. However, micro machining is limited small-scale parts machining because micro tool is very small and weakness to generate signal in micro machining process. Therefore, this study has efficient sensing technology for real monitoring system in micro machine that is proposed to supplement a disadvantage of single-sensor by multi sensor. From experimental result, it was evaluated tool wear and cutting situation according to repetitive slot cutting condition and changing cutting condition, and it was performed monitoring spindle rpm and condition according to compare acceleration signal with current signal.

Purpose: The purpose of this study was to examine the difference of family relationship and health promoting behaviors between two groups depending on presence and absence of climacteric symptoms among middle-aged male. Methods: Samples of 220 men aged between 40 and 64 were recruited from metropolitan areas. The subjects responded to self-report questionnaires on general characteristics, climacteric symptoms, family relationship and health promoting behaviors. Data was collected from September 13, 2016 to September 30, 2016 and analyzed by using t-test, Pearson's correlation efficient, -test, frequency and percentage analysis. Result: In general characteristics of subjects, according to the presence or absence of climacteric symptoms, there were significant differences in occupation( =12.12, p=0.02), average monthly incom ( =11.01, p=0.01), and physical condition( =12.07, p=0.02). Mean scores of family relationship(t=-2.784, p=.008) and health promotion behaviors(t=3.629, p=.000) were significantly higher in climacteric symptom group. Significant positive correlation appeared between family relationship and health promoting behaviors in both presence(r=.493, p=.000) and absence group(r=.698, p=.000). But climacteric symptoms were in negative correlation with family relationship(r=-.187, p=.018) and health promoting behavior(r=-.233, p=.002) only in presence group. Conclusion: This study suggests that family relationship and health promoting behaviors should be considered in developing nursing intervention for climacteric middle–aged males.
