The purpose of this study was measured and analyzed blood pressure, heart rate, brachial-ankle pulse wave velocity(PWV) and ankle brachial index(ABI) between groups to examine the effects of obesity on blood pressure, heart rate and vascular elasticity in 25 obese university students and 30 normal-weight university students. The study results are as follows. First, the obese group had a systolic blood pressure that was 8.77mmHg higher than the normal group, which means there was a statistically significant difference(p<.05). The obese group had a diastolic blood pressure of 0.26mmHg higher too, but there was no statistical significance. Second, the obese group’s heart rate was 2.58 times higher than the normal group’s, but there was no statistical significance. Third, the obese group’s PWV in the right upper extremity was 0.03 lower than the normal group’s and it was 0.05 higher in the left upper extremity, but no statistical significance was found. Fourth, the obese group’s ABI in the right lower extremity was 0.03 lower than the normal group’s and it was 0.02 lower in the left lower extremity, but no statistical significance was found. These results demonstrate the obese group has higher blood pressure and heart rate than the normal group even during resting and thus influences vascular elasticity.

A glucose biosensor using a microdisk resonator in polymeric waveguides was developed by observing either the shift in the resonant wavelength or the variation in the optical power. The deformation in the transfer curve of the vertically coupled resonator sensor resulting from the variation in the disk-to-ring coupling, which was incurred by the application of the target analyte, was suppressed. And the refractive index of the polymeric waveguide was devised to closely follow that of the analyte itself for enhancing the sensitivity of the sensor. The sensitivity and measurement range were observed to be respectively 0.14 pm/(㎎/dL) and 1500 ㎎/dL (theoretically up to 4700 ㎎/dL), for the wavelength shift method and 0.04 ㏈/(㎎/dL) and 140 ㎎/dL the power variation scheme.

Manufacturing enterprises have been doing their best endeavors to obtain global competitiveness using various methodologies, such as IT technology. In order to achieve global competitiveness, they are adopting Manufacturing Execution System (MES) for competitive production. MES is a total management system that manages from the beginning of the production by product order until the quality inspection of the finished product. And MES is an inter-mediator for supplementation of information gap between ERP and inspection machine and equipment. This paper describes on establishment of effective strategy based on BPR methodology and implementation of MES small and medium PCB manufacturing company with multiple-types of products and mixed process flows.
