Objective: To estimate the percentage of households of lung cancer patients with health insurance that suffer catastrophic health expenditure at National Cancer Hospital in 2020. Methods: A cross-sectional study on 102 lung cancer patients who have been treated continuously for at least 1 year at the hospital. Results: There is 89.2% of Households experienced financial catastrophe at 20% threshold, 62.7% at 40% threshold. Households of patients in stage IV experienced financial catastrophe at 40% equal to 0.292 patients in stage II-III. Up to 36.3% of patients have ever lacked or could not pay for medical examination and treatment, 29.4% of patients used to spend or could not pay for drugs, 62.7% of patients had to borrow from relatives, or friends; and 42.2% of patients had to use their savings for other purposes to cover the costs of lung cancer treatment. Conclusion: Despite having health insurance, the proportion of households and lung cancer patients experienced financial catastrophe at National Cancer Hospital in 2020 accounts for a large proportion. It is necessary to strengthen communication activities to encourage people to participate in continuously health insurance scheme, improve the rate of screening and early detection of cancer. In addition, it is necessary to expand the list under the payment scope of the Health Insurance Fund as well as enhancing the effectiveness of cancer drug price negotiation to reduce the economic burden for patients.

The study was carried out on raw food materials including pork, fish of all kinds and leafy vegetables at collective kitchens, industrial catering establishments at factories and enterprises. in Quang Ngai province from January to November 2021. The study aims to: determine the percentage of fresh ingredients at the collective kitchens of factories and enterprises in the area of Quang Ngai province meeting food safety criteria and study some related factors between fresh ingredients meeting food safety criteria and the origin of fresh raw materials in the study area. The results by sampling method of cross-sectional study showed that: 100% of pork met with the lean substances Salbutamol, Clenbuterol, Cimaterol by quantitative method; 13.9% fish met safety criteria for urea by quantitative method; 53.4% ​​of leafy vegetables met safety criteria for pesticides by qualitative method.

In this paper, we present a design of a concurrent dual-band power amplifier operating at 5.8 GHz and 9.4 GHz employing a MMIC technology for wireless communications. The active device used is a 0.25 µm AlGaN/GaN HEMT from WIN Semiconductor, Taiwan. The design goal is to achieve the high-efficiency while still retaining other important metrics including output power and power Gain at concurrent dual frequency bands. The performance of the designed amplifier is evaluated at both small and large signal levels through theoretical analyses and simulation using a Keysight ADS simulator. The developed dual-band amplifier delivered a 47% PAE with 30.5 dBm output power and 12.5 Gain at 5.8 GHz, and a 37% PAE with 30.2 dBm output power and 12.2 Gain at 9.4 GHz.
