Current Global Status Research Articles

Die Rol van die Algemene Praktisyn/ - Huisarts in die Handhawing van 'n Gesonde Omgewing

The Rio de Janeiro earth summit placed new emphasis on the ecological crisis. Some researchers predict that there is about 8 years left before a totality irreversible systems collapse of the earth will occur, unless timely action is taken. This paper summarises the current global and South African status of the ecological crisis, as well as the immediate and future health effects ensuing from it. Both the general and the occupational environment are addressed. As a well informed and respected member of any community, the family physician has a crucial role to play in protecting the environment. Ways of doing this include; active involvement in environmental health matters in a given community; involvement in occupational health at employing institutions, involvement in the development of communities ; sensitivity to environmental causes of ill health and environmental friendly medical practice.

Progress in worldwide control and elimination of disease through immunization

Routine immunization against childhood diseases has been so successful in recent years that many vaccine-preventable diseases occur infrequently in the United States. Many pediatric residents now comptete training without encountering a single child with poliomyelitis, diphtheria, tetanus, or measles (rubeola). As a result, some pediatricians may have lost sigh t of the continuing impact these diseases have on child health in other parts of the world. Some seem surprised to learn, for example, that almost 2 million children still die annually from measles, and another 800,000 infants die each year from neonatal tetanus (Table I). Despite the continuing toll of these disease, great strides have been made over the past decade toward improving rates of immunization among all children. One important contributor has been the Expanded Programme on Immunization of the World Health Organization. Our purposes are to familiarize pediatricians with the strategies and accomplishments of this program, to review the current global status of several vaccine-preventable childhood diseases, and to outline strategies for improvement in the years ahead

Long-term and continuous large-scale exploitation has increasingly exhausted shallow metal mineral resources, and deep mining has become inevitable. The current global status of deep mining of metal mineral resources was presented, a series of engineering challenges faced by deep mining were systematically analyzed, and some progress and future innovation focus in key engineering technologies, such as the prediction and prevention of rockburst, cooling techniques, rock support techniques, deep hoisting techniques, and several nontraditional deep mining techniques, were highlighted. Meanwhile, new insights into development strategies of deep mining technology were proposed. The integration of these forward-looking key innovative technologies will form the overall framework of an innovative technology system for the deep mining of metal minerals. This technology system will help to achieve safe, efficient, and green exploitation of deep underground metal mineral resources and ensure the sustainable development of the metal mining industry.
