Background: The distribution of childhood nutritional diseases is shifting from a predominance of under nutrition to a dual burden of under-and over nutrition in low and middle income countries. Rapid economic development and urbanization lead to an increase in overweight and obesity and diet-related chronic diseases. The co-existence of under-and over nutrition is double burden and this is a public health challenge for community. Objective: To find out the nutritional status of primary school children. Method: The study was school based descriptive study and conducted during November 2014 to February 2015 in basic primary schools, basic middle schools and basic high schools in urban and rural area of Yangon, Mandalay, Taungyi and Mawlamyaing. A total of (2937) Grade IV and Grade V students were measured for weight, height and 592 students were measured for haemoglobin by standard equipment and standard procedure. Results: The overall prevalences

The research problem in this study is the longitudinal optical phonon energy on metal/semiconductor interface for high performance semiconductor *** research solution is to make the software model with finite difference time domain(FDTD)solution for transmission and reflection pulse between metal and semiconductor interface for carrier dynamics *** objective of this study is to find the quantum mechanics understanding on interface engineering for fabricating the high performance device for future semiconductor technology *** analysis was carried out with the help of *** quantum mechanical spatial field on metal-semiconductor stripe structure has been analyzed by FDTD *** emission reveals a characteristic polar radiation distribution of electric dipoles and a wavelength independent of the structure size or the direction of emission;consequently,it is attributed to thermally generate electric dipoles resonating with the longitudinal optical phonon *** energy occurs lattice vibration of material by the polarization of light,if the material has rigid structure reflect back the incident ***,high reflective metal-semiconductor structure always use as photodectors devices in optical fiber *** lattice vibration material structure has no phonon effect,so this structure based devices can get high performance any other structure based *** transmission and reflection coefficient of metal-semiconductor GaN/Au layer structure compare with GaN/Ti and GaN/Pt ***(P)and transverse(S)polarization of light incident on a metal-semiconductor nanolayer structure with IR *** use of the layer by layer(LbL)method to fabricate nanofilms requires meeting certain conditions and limitations that were revealed in the course of research on model systems.
