Abstract Background：Groundwater serves as the drinking water source, which chemical components directly affect human health. Different regions own their groundwater hydro-chemical characteristics based on various geological, hydro-geological conditions, human activities. From the perspective of human health, it is necessary to select groundwater quality health risk assessment （GQHR） factors combined with hydro-chemical characteristics of different regions.Methods：In this paper, taking Tongzhou of Beijing,China as the study area, according to the groundwater hydro-chemical characteristics, NO3-, NO2-, NH4+ and F- were extracted as assessment factors to evaluate the GQHR. Based on GQHR results, the formation and concentration characteristics of health risk factors and the prominent controlling role of influencing risk distribution were explored from natural and human factors. Furthermore, the targeted measures to prevent the increase of groundwater health risk were put forward.Results：Assessment factors: NO3-, NO2- and NH4+ are derived by human factors, such as sewage irrigation, fertilization, and F- stems from irrigation of geogenic high fluoride groundwater and fertilizer use. Still, their distribution is affected by natural factors (geology, geomorphology, and climate). The GQHR follows the order: children > adult females > adult males. The low and medium risk regions are located in upper groundwater, which are mainly controlled by natural factors (groundwater depth, aquifer medium, hydraulic conductivity coefficient, etc.) The measures to prevent the increase of groundwater health risk are to control the pollution sources and reduce the change of groundwater hydrodynamic conditions. The high-risk regions are located in eastern part of the study area, which are affected by both natural and human factors. The preventative measures are to reduce pollution caused by human factors and scientific groundwater resource exploitation and management. Conclusions：In this study, corresponding preventative and control measures were proposed for health risks caused by different dominant control effects. Meanwhile, the research results provide a scientific basis for the safety of groundwater supply and environmental exposure in this area. The research ideas and methods can be used as a reference for similar studies.

Micronutrient Intake

Nutrition is important for human health in all stages of life - from conception to old age. Today we know much more about the molecular basis of nutrition. Most importantly, we have learnt that micronutrients, among other factors, interact with genes, and new science is increasingly providing more tools to clarify this interrelation between health and nutrition. Sufficient intake of vitamins is essential to achieve maximum health benefit. It is well established that in developing countries, millions of people still suffer from micronutrient deficiencies. However, it is far less recognized that we face micronutrient insufficiencies also in developed countries.

Abstract. The Human Factors Analysis and Classification System (HFACS) methodology was applied to accident reports from three African countries: Kenya, Nigeria, and South Africa. In all, 55 of 72 finalized reports for accidents occurring between 2000 and 2014 were analyzed. In most of the accidents, one or more human factors contributed to the accident. Skill-based errors (56.4%), the physical environment (36.4%), and violations (20%) were the most common causal factors in the accidents. Decision errors comprised 18.2%, while perceptual errors and crew resource management accounted for 10.9%. The results were consistent with previous industry observations: Over 70% of aviation accidents have human factor causes. Adverse weather was seen to be a common secondary casual factor. Changes in flight training and risk management methods may alleviate the high number of accidents in Africa.

This article focuses on a major human factors–related issue that includes the undeniable role of cultural factors and cockpit automation and their serious impact on flight crew performance, communication, and aviation safety. The report concentrates on the flight crew performance of the Boeing 777–Asiana Airlines Flight 214 accident, by exploring issues concerning mode confusion and autothrottle systems. It also further reviews the vital role of cultural factors in aviation safety and provides a brief overview of past, related accidents. Automation progressions have been created in an attempt to design an error-free flight deck. However, to do that, the pilot must still thoroughly understand every component of the flight deck – most importantly, the automation. Otherwise, if pilots are not completely competent in terms of their automation, the slightest errors can lead to fatal accidents. As seen in the case of Asiana Flight 214, even though engineering designs and pilot training have greatly evolved over the years, there are many cultural, design, and communication factors that affect pilot performance. It is concluded that aviation systems designers, in cooperation with pilots and regulatory bodies, should lead the strategic effort of systematically addressing the serious issues of cockpit automation, human factors, and cultural issues, including their interactions, which will certainly lead to better solutions for safer flights.
