Multi-touch sensing exists in a number of applications and is presently used in personal computing devices (i.e. Laptops and desktop computers), mobile touch screens, kiosks, interactive wall displays (i.e. subway station map), ATMs, and any display requiring an interactive platform. Current multi-touch sensing methods use capacitive and or resistive based touchscreens both which are expensive and difficult to make. Infrared based touchscreens is being studied as an alternative method that is effective and low-cost solution of producing equal results particularly with large interactive displays. Previous research using infrared based touch screens is not new and has been studied using several implementations and a trade-off decision must be made when considering which technology to use. Our approach combines two infrared based technologies together to effectively eliminate limitations placed on the touch screen when only one implementation is used and reduces the complexity of design and cost.

We grasped the information on how working in the beauty industry influenced the students and the new trends of working field in the industry. We want this treatise to be a great source for the students in the future who are seeking for their career. We surveyed 360 students of Seoul and the Kyeonggi province and here are the results. the students majoring beauty related majors' big concern was, the atmosphere of salons relations between co-workers, and the personality of the owner. Therefore, the maintenance was the most concern for the students. Furthermore, the training system, payment designers' skill salon maintenance system, holidays, working time, and benefit package were the other considerations. Accordingly, we can tell that students are considering the more humane fact weather they can learn and develop their skills, more than concerning about payments or working atmospheres.

Herein, we report synthesis of Co3V2O8 nanoparticles for an electrocatalyst of seawater batteries. The cellusing Co3V2O8 achieves a higher voltage efficiency of76% than72% of the cell without catalyst. Inaddition, the Co3V2O8 shows a good rate capability with reduced voltage gaps and an increased powerdensity of5.9 mW cm 2. This cell is stable over 20 cycles for 400 h with reduced voltage gap of0.95 V. Thesefindings are attributed to the facilitated redox kinetics of the clustered Co3V2O8 nanoparticlesarising from the optimal metal OH bond strength and large surface area.

This study investigates the characteristics, development trends, and airworthiness criteria of key technologies of electric propulsion systems for electric aircrafts. Additionally, previously developed airworthiness certifications for electric aircrafts and propulsion systems were analyzed, and the characteristics of each airworthiness criterion were comparatively analyzed. In conclusion, it is believed that the electric propulsion system for military aircrafts can be applied for developing separated airworthiness criteria by modifying SC-E-19, SC-VTOL, ‘Standard airworthiness certifications for military aircraft Part 3’.
