  • In this paper, an IoT system which is increasingly popular in these days is developed. Among various international standards on the area, one M2M communication protocol is used in the system. The 0neM2M-based IoT system consists of ADN-AE modules and CSE modules. The ADN-AE module provides applications of various services. It also monitors a CSE module. The CES module is a platform that provides common services which should be provided to various AEs in an IoT system. The CSE module consists of a Network Manager module, a Message Handler module, and a Resource Manager module. The Network Manager module controls oneM2M communication and data flow in the system. The Message Handler module processes transmitted messages and the Resource Manager module manages the Resource Tree. The resource tree stores information of the objects to be managed in the system. Also, internal data flow and protocol mapping in the modules are explained.

  • The purpose of this study was to examine the intake of Cr, Cu, and Zn, which play important roles in lipid metabolism, and the relationship of these microminerals with serum lipids of healthy college living in the Choongnam area. The nutritional status of the subjects(35 women) was evaluated based on anthropometric measurements, 24-hr dietary recall for 3 days. Three-day meals and fasting blood were collected to analyze Cr, Cu, and Zn. The mean age, height, weight and BMI were 20 years, 158 cm, 55kg and 22.42kg/$m^2$ respectively. The mean daily energy intake was 85.9% of RDA for Koreans. The ratio of energy from carbohydrate, protein and fat was 60 : 24 : 16. The mean daily intake of Cr, Cu, and Zn was 60.07 $\mu\textrm{g}$/day, 2.64 mg/day, and 11.35 mg/day, respectively. The mean serum levels of Cr, Cu, and Zn were 143$\mu$g/dl, 81.34$\mu$g/dl, adn 101.54$\mu$g/dl, respectively. The mean serum levels of total cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol were 158.56mg/dl, 29.27 mg/dl, 56.00mg/dl, 6.12mg/dl, respectively. In conclusion, the subjects of the present study were healthy and consumed normal levls of dietary Cr, Cu and Zn, which play roles in lipid metabolism. Therefore, serum lipids of the subjects were all in the normal range. There was no significant correlation between dietary microminerals and serum lipids.
