Assayed value of LDL cholesterol was compared with calculated value of LDL cholesterol by Friedewald and DeLong etc, determine its clinical usefulness. When the lipid profiles are in the normal ranges, the calculated value correlated well enough to the assayed value to be clinically useful. However, when the lipid profiles are abnormally high, the values of two methods did not correlate well to be useful. Therefore it is considered that the Cardiac Risk Factor should be determined by actually assaying the LDL cholesterol.

This paper presents the development of an IoT system for online monitoring and management of book sterilizer using Ultraviolet(UVC) LEDs. We developed OMS(Online Maintenance System) to store, manage, and analyze daily operation data of major parts collected through the data collection board. This system allows to evaluate the failure of the maJor components of the book sterilizer and predict the remaining life for predictive maintenance.

The Seoul Clinical Laboratories(SCL), a branch of the Seoul Medical Science Institute undertook CBC examination on l, 039 male and 527 female healthy individuals from May 1st. through July 31 th. 1991. Coulter S-Plus II was used for CBC and the data was handled with modified statistical method by SAS PC program. 13 parameters of CBC of both male and female groups were separately studied. The majority of items were comparable to the normal distribution pattern. However, some items were not in accord with normal pattern. There were minimal difference between data treated with Mean± 2SD and non parametric method. Among 13 items, Hb, Hct, platelets were slightly higher than many previously published data and other items are almost identical. There seems to be ahead for better scientific approach to handle statistics utilizing ever improving software program and continuous studies on normal data.
