This study was conducted to evaluate effects of dietary pine cone meal on egg production, egg quality, serum cholesterol and cholesterol content and fatty acid composition of egg yolk in laying hens. The total of 252 (51-wks) Hy-line brown commercial hens were used for 5 weeks. Dietary treatments included 1) T1 (basal diet + 1% cottonwood sawdust), 2) T2 (basal diet + 0.5% cottonwood sawdust + 0.5% pine cone meal) and 3) T3 (basal diet + 1% pine cone meal). During the overall period, there was no significant difference in egg production, egg weight and egg quality among the treatments. Lipids profile(total, HDL, LDL cholesterol and triglyceride) in serum was not affected by treatments. Egg yolk cholesterol was not significantly different among the treatments. In fatty acid contents of yolk, C18:3 was higher in T1 treatment than T3 treatment(P<0.05). Total SFA, PUFA, MUFA and UFA/SFA were not significantly different in experimental period. In conclusion, dietary supplementation of pine cone meal affected C18:3 fatty acid content of yolk in laying hens, without any adverse effect on egg production.

Drones, which were early operated by remote control, have evolved to enable autonomous flight by combining various sensors and software tools. In particular, autonomous flight of drones was possible since the application of GNSS-RTK (global navigation satellite system with real-time kinematic positioning), a precision satellite navigation technology. For instance, unmanned drone delivery based on GNSS-RTK data was demonstrated for pizza delivery in Korea for the first time in 2021. However, the vulnerabilities of GNSS-RTK should be overcome for delivery drones to be commercialized. In particular, jamming in the navigation system and low positioning accuracy in urban areas should be addressed. Solving these two problems can lead to stable flight, takeoff, and landing of drones in urban areas, and the corresponding solutions are expected to establish a hybrid positioning technology. We discuss current trends in hybrid positioning technology that can either replace or complement GNSS-RTK for stable drone autonomous flight.

When ICP(Inductive Coupled Plasma) type etching and wafer manufacturing is being processed m semiconductor process, a noxious gas in PFC and CFC system is generated Gas cleaning dry scrubber is to remove This noxious gas. This paper describes a power source device, 2MHz switching frequency class 2kW RF Generator, used as a main power source of the gas cleaning dry scrubber. The power stage of DC/DC converter is consist of full bridge type converter with 100kHz switching frequency. Power amplifier is push pull type inverter with 2MHz switching frequency, and transmission line transformer The adequacy of the circuit type and the reliability of generating plasma In various load conditions are verified through 50Ω dummy load and chamber experiments result
