Development of a Formalized Mentorship Program for Newly Licensed Registered Nurses at a Large Community Medical Center
Retention, competency, job satisfaction, and lateral violence are issues facing the nursing workforce, especially newly licensed registered nurses (NLRNs). The United States is facing a nursing shortage; therefore it is important to develop strategies to retain qualified registered nurses (RNs). The Master of Science in Nursing/Clinical Nurse Leader (MSN/CNL) student team conducted a literature review on how to address these issues. A mentorship program is the proposed intervention to assist novice nurses during their transition into the nursing role. The student team performed a needs assessment through surveys and interviews to gain valuable data on the medical center. The assessment informed recommendations for implementation and evaluation of a mentorship program. Results showed that positive responses for a mentorship program from both staff nurses and nursing leadership. Common themes emerged and assisted in the development of the recommendations for the medical center

Prevalence of Accidents and Injuries and Related Factors of Fishermen Fishing Offshore in the North of Vietnam
Introduction: Seafaring, particularly offshore fishing, exposes fishermen to various occupational risks leading to diseases and injuries. This study aimed to determine the prevalence of occupational risks, injury accidents, and contributing factors among offshore fishers in North Vietnam, to develop evidence-based recommendations to enhance their safety and well-being.
Methods: A cross-sectional study was conducted involving 420 fishermen with a minimum of two years of experience. Interviews were conducted between 2018 and 2020.
Results: The findings indicated that there is a 41.7% prevalence of accidents and an average injury rate of 280.2 per person per year. Most incidents occurred at night with 104 cases (59.4%), slips and falls 48 cases (27.4%), broken winch lines 40 cases (22.9%), and ship collisions 14 cases (8.0%) being the primary causes. The most common injuries included soft wounds in 92 cases (52.5%) and sprains/dislocations in 14 cases (8.0%). Fishermen with fewer than 10 years of experience exhibited a higher accident risk (odds ratio = 1.54; 95% confidence interval: 1.05-2.72), as did those in the role of a fisherman (odds ratio: 1.68; CI: 0.97-2.94) and those working without labor protection (odds ratio: 3.68; CI: 1.05-12.93).
Conclusion: Lack of labor protection equipment increased the risk by 3.68 times, and fishermen in the friend group had a 2.02 times higher risk of injury. Addressing these risks requires adherence to labor protection regulations and safe working procedures
Application of Kalman Filter and Breeding Ensemble Technique to Forecast the Tropical Cyclone Activity
Tropical cyclone (TC) is one of the major meteorology disasters, as they lead to deaths, destroy the infrastructure and the environment. Therefore, how to improve the predictability of TC’s activities, such as formation, track, and intensity, is very important and is considered an important task for current operational predicting TC centers in many countries. However, predicting TC’s activities has remained a big challenge for meteorologists due to our incomplete understanding of the multiscale interaction of TCs with the ambient environment and the limitation of numerical weather forecast tools. Hence, this chapter will exhibit some techniques to improve the ability to predict the formation and track of TCs using an ensemble prediction system. Particularly, the Local Ensemble Transform Kalman Filter (LETKF) scheme and its implementation in the WRF Model, as well as the Vortex tracking method that has been applied for the forecast of TCs formation, will be presented in subSection 1. Application of Breeding Ensemble to Tropical Cyclone Track Forecasts using the Regional Atmospheric Modeling System (RAMS) model will be introduced in subSection 2

DESIGN AND ANALYSIS OF COMPACT METAMATERIAL MIMO ANTENNA FOR WLAN APPLICATIONS
A compact three-port metamaterial multiple-input-multiple-output (MIMO) antenna using complementary split-ring resonator (CSRR) loaded ground have demonstrated in order to miniaturize the size and improve the antenna performance. The antenna is designed on FR4 material and simulated by HFSS software. By loading CSRRs in the ground plane, the size reduction of 77% of the individual patch antenna element is achieved, which appeared to be the major reason for the obtained the compact MIMO antenna. Furthermore, the simulated results show that the proposed MIMO antenna achieves the total gain higher than 5 dB, the isolation less than -11 dB, the envelope correlation coefficient (ECC) value lower than 0.015, and the bandwidth of 100 MHz through the whole WLAN band from 2.4 GHz to 2.484 GHz, indicating promises for WLAN applications
