Objectives: To measure the level of job satisfaction among primary health care physicians Ministry of Health (MOH) Primary Healthcare Center (PHC) physicians, to evaluate the physicians’ mental health, and to assess their associated factors. Study Setting: Kuwait Ministry of Health, Primary Care Centers. Study Design: Cross-sectional study. Data Collection: The study was conducted from July to September, 2017. Of 746 questionnaires distributed to all PHC physicians in the MOH, 417 questionnaires were completed. Information was collected on socio-demographic characteristics, work and health-related factors, job satisfaction (using the Warr-Cook-Wall job satisfaction scale), and mental health (using General Health Questionnaire). Principal Findings: Of participants, 40.8% were male, and 24.9% were Kuwaitis. Median overall job satisfaction was 71.4%. There were significant differences in overall job satisfaction with the physician rank (p = 0.008) and governorate (p = 0.05). The GPs were moderately satisfied with work surroundings;work freedom;recognition;degree of responsibility;salary;opportunity to use abilities;attention given to suggestions;relationship with hospital physicians, colleagues, and fellow workers;relations between management and workers;working hours;and the amount of variety in their job, but more satisfied with their immediate supervisors. Conclusions: Job satisfaction of PHC physicians is critical for the improvement of health systems. This study showed that GPs (General Practitioners) were more satisfied overall than previously reported studies done in Kuwait. They were moderately satisfied with their salary and the amount of variety in work.

The development of high-performance non-precious metal-based robust bifunctional electrocatalyst for both hydrogen evolution reaction(HER) and oxygen evolution reactions(OER) in alkaline media is essential for the electrochemical overall water splitting technologies. Herein, we demonstrate that the HER/OER performance of Co Se_(2)can be significantly enhanced by tuning the 3d-orbital electron filling degree through Mo doping. Both density functional theory(DFT) calculations and experimental results imply that the doping of Mo with higher proportion of the unoccupied d-orbital(P_(un)) could not only serve as the active center for water adsorption to enhance the water molecule activation, but also modulate the electronic structures of Co metal center leading to the optimized adsorption strength of*H. As expected, the obtained Mo-Co Se_(2)exhibits a remarkable bifunctional performance with overpotential of only 85 m V for HER and 245 m V for OER to achieve the current density of 10 m A/cm^(2)in alkaline *** work will provide a valuable insight to design highly efficient bifunctional electrocatalyst towards HER and OER.

Orthogonal frequency division multiplexing (OFDM) waveform is promising to converge communications and sensing functionalities for future wireless applications. This paper presents a novel method to improve the OFDM-based sensing accuracy by estimating the delay/Doppler leakages in the channel matrix, which is constructed by the received and the transmitted OFDM symbols. Both simulation and proof-of-concept experiment validate the proposed method for sensing *** experiment uses a heterodyne W-band system at 97 GHz to transmit and receive an OFDM waveform of bandwidth 3.9 *** achieve an improvement in sensing accuracy by an order of magnitude which is significant for OFDM-based converged systems.
