The administrative management of skills on both qualitative and quantitative levels is one of the essential functions of a health system. To better implement policies of fight against High Blood Pressure (HBP) and other chronic diseases, it is important to establish strategies to retain health personnel. This loyalty requires favorable working conditions and consideration of the contribution-reward couple. Good working conditions are likely to reduce the phenomenon of medical nomadism;conversely, poor HR management can contribute to their exodus towards exotic “green pastures”, thus leading to an additional crisis in the Cameroonian health system. The fight against HBP is a complex, multifaceted and multifactorial reality that requires appropriate management model for all types of resources mainly HR. The main objective of this research is to show the impact of poor management of human resources in Cameroon health system on medical nomadism and the ineffectiveness of the fight against High Blood Pressure. Method: A cross-sectional descriptive survey among five hundred (500) health facilities in the center region of Cameroon has been conducted. A stratified probabilistic technique has been used, and the number of health facilities to be surveyed has been determined using the “sample size estimation table” of Depelteau. The physical questionnaires have been printed and then distributed to data collectors. After data collection, the latter were grouped during processing in Excel sheets. The Chi-square test was used for data with a qualitative value and that of Kolmogorov-Sminorf for data with a quantitative value to assess the normality and reliability of data. The Crochach’s Alpha reliability test allowed us to have a summary of the means and variances and then to search for intragroup correlations between variables. Descriptive analysis was possible with the XLSTAT 2016 software. Results: 43.60% of Health Facilities (HF) managers were unqualified. 82.20% of HF managers have staff in a situation of professional insecurity. They are mainly contractual (49.00), decision-making agents (24.40%), casual agents (08.80). The proportion of unstable personnel is average of 22.00% and very unstable, 12.00%.展开更多

Inner Mongolia grassland is a sensitive and vulnerable area of climate and an important region for adaptation to climate change. New climate change adaptation approaches with nomadic culture characteristics should be exploded in the context of climate warming. In this paper, the different utilization pattern of grassland in different regions, the different modes of production and management and historical culture were analyzed first in Nenjiang-West Liaohe plain and Ke'erqin region, Inner Mongolia Plateau and Ordos Plateau. Then, nomadic culture on the grassland was discussed from the productivity to biodiversity, from local livestock variety to resource-used system. Finally, new approaches of climate change adaptation with inheriting the essence of nomadic culture were proposed, including protecting biodiversity and using resources reasonably, performing a practice of grazing suspension-rotational grazing system,fencing degenerated grassland to facilitate its growth, founding new farming and husbandry system on the grassland, and establishing an incentive mechanism favorable to grassland and ethical cultural protection.展开更多

The body of terrorism rests not on ideology/beliefs/religions-it is purely a practical idea, behind which there is only one thing: terra nova-the habitat. It is necessary to look for other reasons for the massacres and public executions of modern times, because no religion calls for open murder-only dogmatists armed with faith, craved crusaders hikes, and therefore cannot be recognized and accepted as responsible for the murder. This is the search for the guilty, but only the person is guilty-the fault is his area of responsibility. The Utopians of Thomas More, who revered Mithra, acted like him: like Greek gods, they interfered in human wars, descending from heaven, and restored justice by waging war beyond their state borders, as if protecting the inviolability of their territory and their laws, whose rejection, like, and encroachment on them, led to armed conflicts, the purpose of allowing them was the introduction of forced disciplina (established order), sanctioned by Mithra himself. It is this identity that allows us to consider Utopia as an extended invective for the entire social order, regardless of time and place, and in particular the state as a paramilitary mechanism for the improvement of the human hostel, based on regulations that allow and, more often, provoke its violation, since destabilization is the driving force of existence. This polar involvement of Mithra in the war lies hidden in the very aporia of the world-war, which turns the god of treaties into the chthonic deity of destruction and murder.展开更多

The disease is common in most developing countries, the human mortality rate is about 2%, and the disease causes severe rheumatism, infertility in males, spontaneous abortion and also results in wastage of resources through prolonged treatment. Brucella organisms are also potential biological weapon which could be cheaper to produce but more devastating than chemical weapons. About 5 mililitres of blood was drawn from 228 subjects using sterile vacutainers and analyzed by using standard tube agglutination tests: (SAT3 160) and ELISA (IgG, IgM) kits specific for Brucella abortus and Brucella melitensis antibodies. Semi structured questionnaire was administered to collect data. In the study, overall sero prevalence was 70 (30.8%). More male participated in the study with a frequency of 24.6% of whom 7.92% falls within the age group of 20 to 30, followed by 31 - 35 years with 5.72% and 3.52% within 36 - 45 years. Least affected were those in the age groups above 46 years (2.20%). Approximately, 21.54% of the subjects had formal education either at Quranic, primary and secondary or tertiary level. Majority acquired Quranic education (9.68%), 7.48% primary and 0.88% had tertiary training. A total of 21 (9.24%) never acquired any form of education. Headache, muscle aches, malaise, chills and fatigue were the most common clinical signs and symptoms experienced by about 30% among the participants. In the distribution of Brucella antibodies, ELISA diagnostic kits showed high sensitivity with the prevalence rate of 18.04% (n = 41) followed by SAT 12.76% (n = 29). The sensitivity and specificity of RDPT kits were 37 % and 69%, with a positive and negative predictive value of 18% and 86% respectively. Unprocessed milk from the market and consumption of unboiled milk were associated with brucellosis. Therefore, patients with brucellosis should be treated to prevent the devastating effect of the disease and the accompanying sequelae, public health education programs should explain modes of transmission and Brucella febrile diagnostic kit should be used at the health facilities.展开更多

The above conditions contribute to the types and nomadic features of traditional Mongolian furniture. Most traditional Mongolian furniture has a box-like structure, and the nomadic features are reflected in the following aspects: made of local materials; small size for the application in Mongolian yurt; demountable and foldable for the convenience of transportation,because Mongolians have to move to different grasslands for grazing; the furniture parts is bulky for frequent transportation; and colored drawing and carved furniture enrich the life color.展开更多
