| 1 | Development of underground mine monitoring and communication system integrated ZigBee and GIS显示文摘An automated underground mine monitoring and communication system based on the integration of new technologies is introduced to promote safety and health,operational management and cost-effectiveness.The proposed system integration considering Wireless Sensor Network(WSN) assisted Geographic Information System(GIS) enables to monitor and control underground mining applications from surface office.Based on the capabilities of WSNs,ZigBee network is adapted for near real-time monitoring,ventilation system control and emergency communication in underground mine.ZigBee nodes were developed to sense environmental attributes such as temperature,humidity and gases concentration;switching ON and OFF ventilation fans;and texting emergency messages.A trigger action plan for monitored attributes above normal and threshold value limits is programmed in the surface GIS management server.It is designed to turn the auxiliary fans on remotely or automatically in orange condition and sending evacuation messages for underground miners in unsafe(red) condition.Multi-users operation and 3D visualisations are other successful achievements of the proposed system for the underground monitoring and communication. | Moridi Mohammad Ali Kawamura Youhei Sharifzadeh Mostafa Chanda Emmanuel Knox Wagner Markus Jang Hyongdoo Okawa Hirokazu | 2015 | International Journal of Mining Science and Technology2015，25，5： | 11 |
| 2 | Review of the malaria epidemiology and trends in Zambia显示文摘A comprehensive desk review of malaria trends was conducted between 2000-2010 in Zambia to study malaria epidemiology and trends to guide strategies and approaches for effective malaria control.This review considered data from the National Health Information Management System,Malaria Surveys and Programme Review reports and analyzed malaria in-patient cases and deaths in relation to intervention coverage for all ages.Data showed three distinct epidemiological strata after a notable malaria reduction(66%)in in-patient cases and deaths,particularly between 2000-2008.These changes occurred following the(re-)introduction and expansion of indoor residual spraying up to 90%coverage,scale-up of coverage of long-lasting insecticidetreated nets in household from 50%to 70%,and artemisin-based combination therapy nationwide.However,malaria cases and deaths re-surged,increasing in 2009-2010 in the northern-eastern parts of Zambia.Delays in the disbursement of funds affected the implementation of interventions,which resulted in resurgence of cases and deaths.In spite of a decline in malaria disease burden over the past decade in Zambia,a reversal in impact is notable in the year 2009-2010,signifying that control gains are fragile and must be sustained toeliminate malaria. | Freddie Masaninga Emmanuel Chanda Pascalina Chanda-Kapata Busiku Hamainza Hieronymo T Masendu Mulakwa Kamuliwo Wambinji Kapelwa John Chimumbwa John Govere Mac Otten Ibrahima Soce Fall Olusegun Babaniyi | 2013 | Asian Pacific Journal of Tropical Biomedicine2013，3，2： | 2 |
| 3 | A retrospective evaluation of the quality of malaria case management at twelve health facilities in four districts in Zambia显示文摘Objective:To establish the appropriateness of malaria case management at health facility level in four districts in Zambia.Methods:This study was a retrospective evaluation of the quality of malaria case management at health facilities in four districts conveniently sampled to represent both urban and rural settings in different epidemiological zones and health facility coverage.The review period was from January to December 2008.The sample included twelve lower level health facilities from four districts.The Pearson Chi-square test was used to identify characteristics which affected the quality of case management.Results:Out of 4891 suspected malaria cases recorded at the 12 health facilities,more than 80%of the patients had a temperature taken to establish their fever status.About 67%(CI_(95)66.1-68.7)were tested for parasitemia by either rapid diagnostic test or microscopy,whereas the remaining22.5%(CI_(95)213.1-23.7)were not subjected to any malaria test.Of the 2247 malaria cases reported(complicated and uncomplicated),71%were parasitologicaily confirmed while 29%were clinically diagnosed(unconfirmed).About 56%.(CI_(95)53.9-58.1)of the malaria cases reported were treated with artemether-lumefantrine(AL),35%(CI_(95)33.1-37.0)with sulphadoxine-pyrimethamine,8%(CI_(95)6.9-9.2)with quinine and 1%did not receive any anti-malarial.Approximately 30%of patients WHO were found negative for malaria parasites were still prescribed an anti-malarial,contrary to the guidelines.There were marked inter-district variations in the proportion of patients in WHOm a diagnostic tool was used,and in the choice of anti-malarials for the treatment of malaria confirmed cases.Association between health worker characteristics and quality of case malaria management showed that nurses performed better than environmental health technicians and clinical officers on the decision whether to use the rapid diagnostic test or not.Gender,in service training on malaria,years of residence in the district and length of service of the health worker at the facility were not associated with diagnostic and treatment choices.Conclusions:Malaria case management was characterised by poor adherence to treatment guidelines.The non-adherence was mainly in leans of:inconsistent use of confirmatory tests(rapid diagnostic test or microscopy)for malaria;prescribing anti-malarials which are not recommended(e.g.sulphadoxine-pyrimethamine)and prescribing anti-malarials to cases testing negative.Innovative approaches are required to improve health worker adherence to diagnosis and treatment guidelines. | Pascalina Chanda-Kapata Emmanuel Chanda Freddie Masaninga Annette Habluetzel Felix Masiye Ibrahima Soce Fall | 2014 | Asian Pacific Journal of Tropical Biomedicine2014，4，6： | 1 |
