- PublicationImplementation of Web based GIS Application for Mapping of Health Facilities, Services and Providers in Malaysia(2014)
;Hazrin H ;Tahir A.Fadhli YBackground: This study is to design, develop, create, deploy, test and deliver, together with documentation, help manual and training for web based GIS application of health facilities and services under Ministry of Health, Malaysia. Methods: The system is web-based mapping and navigation can be used with Internet such as Internet Explorer and Mozilla Firefox. The development of web mapping system was programmed by using ArcGIS Server. Tools and GIS software functions will be simplified to allow the search and analysis process can be done more easily. Results: There are four modules in the system created. First module is view for display list of health facilities in the system. Second module is search to obtain information on health facilities, services, providers and specialty. Third module is analysis for gathered an area of geographic information, get ratios facilities, services, and providers of services to the population, analysis of the buffer zone (buffer) to find coverage of a health facility for a certain distance and other geostatistical analysis. Last module is tools for issue the results of the analysis in the form of tables, graphs and maps that can be stored or printed. The system is controlled by the administrator where users need to request to use this application. Discussions: Web mapping can be expanding by using smartphones and tablet that supports Android, iOS and Windows phone. This system can also know the distribution of the disease in real time by appropriate user can update through online. Web mapping application enables user to use the GIS database has information facilities, services and service providers without having to have a deep knowledge in the field of GIS or using GIS software. - PublicationSpatial-temporal analysis for identification of vulnerability to dengue in Seremban district, Malaysia(2014)

A.Dengue is a major public health threat in Malaysia, which is known for the hyperendemicity with all the four serotypes of the dengue virus circulating concurrently. Annual dengue cases reported were 43,000 cases for 2013, and this imposed a heavy toll on the resources for dengue prevention and control program. The objective of mapping in our study is to determine the spatial clustering of the dengue cases and to identify the areas that are vulnerable to dengue outbreaks. A Geographical Information System (GIS) was used to assess the vulnerability of Seremban district. Dengue data were obtainedfrom the Ministry ofHealth. We determined the spatial distribution, the average distance of dengue cases and identified hotspots areas using the Moran'-s -I, Average Nearest Neighbourhood (ANN), Kernel density estimation. Vulnerability to dengue was assessed with the spatial temporal analyses and Local Indicator for Spatial Autocorrelation (LISA). From 2003-2009 Seremban recorded 6076 dengue cases. Moran'-s I showed the cases occurred in clusters with a Z-score of 16.384 (p<0.001). ANN 0.264 (p<0.001) indicated the mean distance between every dengue case was 55 meters. Kernel density estimation showed hotspots of dengue were concentrated in two subdistricts. This paper discusses how spatial-temporal approach can be used to assess the vulnerability of Seremban to dengue where control activities can be more focused to these high risk areas. Mapping the dengue distribution using spatial-temporal approach is useful and guides the public health management of dengue.
