The purpose of our work is to develop a system that can detect and alarm the individual's sitting position of inactive period. Non-wearable sensor system based on FSR includes a H/W device for interfacing between a computer S/W that process sensing data and FSR module as a Sitting Mat. Pressure intensity of each sensing point on computer S/ W can be showned by color change and area expansion and we observe changes in the quantitative and qualitative. Our system has an edge in price competitiveness compared to the existing foreign system by reducing the number of FSR sensor array and improve the sensitivity of Load Measurements with computer S/W algorithm. In the future , it will continue to be developed smartphone apps to check real-time alerts with transmitting data over the bluetooth interface. and we will be expected to develope FSR sensors with durability and ductility by performing clinical trials with Office workers who sit for a long time.

This study conducted a comparative analysis of laser power feedback control by measuring the melting pool size and temperature in the Directed Energy Deposition (DED) of SUS316L, to identify the effect of a conventional melting pool monitoring system on 3D metal printing performance. In the study, a CLAMIR was used on a developing 3D metal printer to control the laser beam power by measuring the size and temperature of the melting pool using an IR camera. Test parts were built from same CAD model but under different conditions, specifically, with CLAMIR on and off. The parts were investigated three ways: by 3D scanning to measure geometric errors, CT scanning to look into pore creation and distribution, and tensile tests to analyze mechanical performance.
