The Relationship

Introduction: The Singapore Armed Forces (SAF) collaborated with the Meteorological Service Singapore (MSS) to study the relationship between weather parameters and the incidents of exertional heat injury (EHI) to mitigate the risk of EHI in a practical manner. Methods: Data from the SAF’s heat injury registry and MSS’ meteorological data from 2012 to 2018 were used to establish a consolidated dataset of EHI incidents and same-day weather parameters rank-ordered in deciles. Poisson regression modelling was used to determine the incidence rate ratios (IRRs) of the EHI, referencing the first decile of weather parameters. Two frames of analysis were performed - the first described the relationship between the weather parameters and the adjusted IRR for the same day (D), and the second described the relationship between the weather parameters and the adjusted IRR on the following day (D+1). Results: For wet-bulb temperature, the IRR on D+1 approximated unity for the first nine deciles but rose to 3.09 at the tenth decile. For dew-point temperature, the IRR on D+1 approximated unity for the first nine deciles but rose to 3.48 at the tenth decile. By designating a single dew-point temperature cut-off at  25.1°C (transition between the ninth and tenth decile), the adjusted IRR on D +1 was 2.26 on days with dew-point temperature  25.1°C,. Conclusion: Integrating the data from the SAF and MSS demonstrated that a dew-point temperature ≥ 25.1°C on D correlates statistically with the risk of EHI on D +1and could be used to supplement the risk mitigation system.

Insulation Performance

The outer surface temperature of cold insulation structure must be higher than air dew point temperature is stipulated in national standard.But the outer surface temperature of cold insulation structure and air dew point temperature normally wave in a certain range with the change of environmental parameters. In Practical application, it is difficult to determine the relationship between these two temperatures. Functional relationship between the outer temperature, air dew point temperature and environmental temperature or humidity is fitted.The influence of the air temperature and humidity is analyzed. Some suggestions about design and evaluation index of cold insulation are offered based on this research.

Bangladesh Coast

During the transition of tropical cyclone in the coast of Bangladesh, it is normally observed that there is a noticeable perturbation of weather parameters around the cyclone landfall zone. Through this research the extent of perturbation is assessed. To make the inventory 4 recent cyclones were selected that had made landfall in Bangladesh coast. They are cyclone MORA, cyclone ROANU, cyclone KOMEN and cyclone MAHASEN. Weather parameters selected to check their perturbation are wind speed, temperature, dew point temperature, atmospheric pressure, relative humidity and precipitation. The dispersion of these parameters from their normal state was measured also in accordance of their distance from the landfall area. To perform the task a time scale of 15 days was selected for each cyclone. Middle 3 days window were considered as most affected weather, 6 days prior and after the event were considered as normal (prevailing) weather. The Synop (observed) data was downloaded from the Ogimet.com. The data was then processed and decoded by Synop decoder and then further analyzed in MS Excel. In case of atmospheric pressure perturbation the highest perturbation was found 5.8 mb low on average than prevailing pressure up to 50 km from cyclone landfall. Wind speed perturbation was highest in 50 to 100 km area. Perturbation of temperature was highest in 0 to 50 km (about 2.1 °C low on average). Perturbation of dew point temperature was found negligible and humidity perturbation was found highest 6.63% high on average up to 50 km of landfall. In case of precipitation perturbation highest was found in 0 to 50 km area of landfall (38.76 mm high on average than prevailing weather), however precipitation perturbation was irregular beyond 100 km of landfall. The most perturbed weather parameter was found atmospheric pressure and the least affected was dew point temperature.

This study is dedicated to the regional history of the East-West conflict on the basis of the relationship between the Germany military and the Belgian armed forces stationed in Germany. The central question it addresses is which factors were largely responsible for the interdependence between actors and institutions of both armies. In addition to analysing the limited time of the peak phase of Belgian military deployment in the Federal Republic 1946–1990, the book concentrates regionally on the military training areas of Vogelsang in the Eifel and the Wahner Heide near Cologne as military contact zones. For this purpose, the author evaluates unpublished archival sources at the local level for the first time.

The Relationship

Extensive research on the relationship between employees' use of English in the workplace and their job performance has revealed that the use of English at work leads to increased job performance and positive interactions among staff. In relation to this, a good command of English among military staff, especially officers, is of great importance to the Armed Forces, as military personnel often serve abroad and need to be proficient in communicating their instructions and orders to a foreign team. Previous research has also shown that self-efficacy is a significant predictor of job performance; however, the role of self-efficacy in learning English language skills has not been widely explored as mediator in the relationship between motivation to learn, intention to share knowledge, and job performance. Therefore, this paper aims to develop a conceptual framework that can be used to improve the understanding of English self-efficacy and its relationship with employees’ motivation to learn, intention to share knowledge, and capability to complete a given task. This framework informs and guides future research that will test the hypothesized relationships. The findings would assist the English Department of the Education Directorate of the Malaysian Armed Forces to design or revise military training syllabi and approaches.
