The aim of this paper was to determine the topographic distribution of gastritis lesions in pigs through an open source geographic information system (GIS) software analysis. The stomachs of 146 Italian heavy pigs were collected at slaughter and subjected to macroscopic pathological examination of the internal mucosa. A total of 623 lesions were either classified as hyperplastic or follicular (97%) with the remaining minority of lesions categorised as atrophic and simple. The hyperplastic gastritis lesions had an average surface of 77.8 cm<sup>2</sup> and were mainly located in an oval shaped area of the fundus region of the stomach near the <em>Curvatura ventriculi major</em>. The follicular gastritis lesions had generally a smaller surface (40.3 cm<sup>2</sup>) and were concentrated in two distinct small areas of the pyloric region. The GIS analysis provided the opportunity to produce useful maps showing the distribution and characteristics of gastritis in pigs.

QGIS is a free and open-source software that allows viewing, editing, and analyzing georeferenced data. It is a Geographic Information System (GIS) software composed by tools that allow to manipulate geographic information and consequently to create maps which help to get a better understanding and organization of geospatial data. Unfortunately, maps created directly in the GIS desktop software are not automatically transferred to a website. This research aimed to compare publishing capabilities in different QGIS plugins to create Web Maps. This study analyzes four QGIS plugins (QGIS2Web, QGIS Cloud, GIS Cloud Publisher and Mappia Publisher), performing a comparison between them, considering their advantages and disadvantages, the free and subscription plans, the tools offered by each plugin and other generic aspects. The four plugins were tested in a specific case study to automatically obtain different Web Maps. This study could help users to choose the most adequate tools to publish Web Maps under QGIS software.

Kajian dialek di Malaysia secara tradisional telah banyak dilakukan. Kajian secara tradisional ini telah menghimpun varian-varian fonologi yang ada sehingga terhasilnya   dialek Melayu di Malaysia. Kemudian ada kemajuan dari segi penghasilan isoglos yang dilakar pada peta secara impresionistik melalui kajian dialek geografi. Namun terdapat kelompongan kajian dialek untuk beberapa ketika sebelum kajian dialek dengan aplikasi Geographic Information System (GIS) diperkenalkan. Kajian berasaskan teknologi mampu melakar peta isoglos dengan teknik overlay dan penandaan choropleth bagi varian bunyi dengan lebih tepat. Artikel ini bertujuan menghuraikan pengaruh penyebaran dialek Melayu Thai dengan mengaplikasikan GIS. Kajian dialek ini telah melibatkan negeri Perlis, Kedah Langkawi, Pulau Pinang dan Perak. Kajian bersifat multidisiplin ini akan menjelaskan bagaimana faktor bukan linguistik seperti bentuk muka bumi, migrasi dan sejarah selain faktor linguistik mencorakkan penyebaran dialek ini di utara Semenanjung Malaysia khususnya. Lebih seribu orang responden yang terlibat dengan tiga kategori usia dikenal pasti, iaitu golongan tua (50 tahun ke atas), dewasa (26-49 tahun) dan remaja (15-25 tahun). Responden telah melalui sesi temu bual dan menjawab soal selidik. Sebanyak empat puluh (40) senarai perkataan yang berkaitan kehidupan responden telah dipilih. Hasil kajian menunjukkan memang   terdapat penyebaran yang meluas dialek Melayu Thai di Malaysia. Yang menarikya, dialek yang tersebar bukan hanya dialek Patani tetapi juga dialek Satun terutama di Langkawi dan Perlis. Aplikasi GIS ternyata bukan sahaja mampu melakar isoglos dengan tepat tetapi dapat membuktikan bahawa faktor bukan linguistik menjadi faktor tambahan kepada mengapa tersebarnya sesuatu dialek itu ke satu-satu kawasan.   Kata kunci: Dialek Melayu, dialek Melayu Thai, Geographic Information System (GIS), isoglos, varian fonologi   ABSTRACT Traditional dialect studies in Malaysia have widely been explored. These studies managed to group all the phonological variants which produce various Malay dialects in Malaysia. Then there were progresses in terms of producing isoglosses which were drew impressionistically on the maps in the studies of geographical dialects. However, there were gaps in the dialect studies for some time before the dialect studies with Geographic Information System (GIS) application was introduced. This technology-based study has the ability to produce isogloss maps using the overlay technique and choropleth marking for the sound variants precisely. This article aims to explain the influence for the dissemination of Thai Malay dialects by applying GIS. This study involves the states of Perlis, Kedah Langkawi, Penang and Perak. This multidisciplinary study explains how non-linguistics factors such as geography, migration and history as well as linguistics factors shape the distribution of the Malay dialects in the northern Peninsular Malaysia in particular. More than a thousand respondents were involved who were divided into three age categories namely, the elderly (50 and older), adults (26-49 years) and adolescents (15-25 years). Respondents were interviewed and required to answer questionnaires. Forty (40) word lists related to respondents' lives were selected. The result shows that there is a widespread of Thai Malay dialects in Malaysia. Interestingly, the dialects are not only the Patani dialect but also the Satun dialect especially in Langkawi and Perlis. GIS application has not only been able to accurately reproduce isoglosses but have proven that non-linguistic factors are additional factors that explained the reasons for dialects to disseminate in an area.   Keywords: Geographic Information System (GIS), isoglosses, Malay dialects, phonological variants, Thai Malay dialects   Cite as: Jalaluddin, N.

Seepage velocity is a very important criterion in infrastructure construction. The planning of numerous large infrastructure projects requires the mapping of seepage velocity at a large scale. To date, however, no reliable approach exists to determine seepage velocity at such a scale. This paper presents a tool within ArcMap/Geographic Information System (GIS) software that can be used to map the seepage velocity at a large scale. The resultant maps include both direction and magnitude mapping of the seepage velocity. To verify the GIS tool, this study considered two types of aquifer conditions in two regions in Iraq: silty clayey (Babylon province) and sandy (Dibdibba in Karbala province). The results indicate that, for Babylon province, the groundwater flows from the northwest to southeast with a seepage velocity no more than 0.19 m/d; for the Dibdibba region, the groundwater flows from the west to the east with a seepage velocity not exceeding 0.27 m/d. The effectiveness of the presented tool in depicting the seepage velocity was thus demonstrated. The accuracy of the resultant maps depends on the resolution of the four essential maps (groundwater elevation head, effective porosity, saturated thickness, and transmissivity) and locations of wells that are used to collect the data.

This research is aimed at predicting erosion and sedimentation in the Ghareh Aghach Basin in the central part of Iran using Erosion Potential Model (EPM) models incorporated into Geographic Information System (GIS) software. This basin has an area of about 8955 hectares. The region has a range of vegetation, geological, soil texture and land use types. The basin was subdivided into 5 sub-basins. Data required for this study were collected in part through published reports, whilst the remaining was derived by field surveys. Necessary maps in EPM models were prepared in Autocad-2006 medium and were transported to IILWIS, after some revision. After constructing topologies for all polygons, we entered weightings for all layers within the Arc-View software. Combinations of all layers were managed thereafter. Coefficient of each factor was determined, and erosion intensity coefficient (Z) was calculated. Four layers for EPM model were combined to develop the final layer of erosion and sedimentation. The results of the EPM model for homogenous and uniform sampling units showed that 0.19% (16.7 ha) of the total watershed area were classified as class I of erosion category with very low sedimentation and 15.1% (1352 ha) were classified as class II of erosion category with low sedimentation and 41.3% (3699 ha) were classified as class III of erosion category with medium sedimentation and 13.2% (1175 ha) were classified as class IV of erosion category with high sedimentation and finally 30.2% (2711 ha) were classified at class V of erosion category with very high sedimentation, respectively. The result of comparing erosion and sediment values using an EPM model with measured values showed that no significant difference was observed between the estimated and measured values ( P < 0.05).
