A study to assess household food insecurity was carried out among 150 n=150) households in Mukim Kemumin, Kota Bharu, Kelantan. Apart from this study, an assessment of nutritional status and dietary pattern of children of the selected
household aged below 12 years old was implemented, where a total of 150 households were selected through proportion sampling
Online 3D Terrain Visualization: Implementation and Testing
Geographical Information Systems (GIS) and three dimensional (3D) World Wide Web (WWW) applications usage are on the rise.The demand for online 3D terrain visualization has increased not just for cartographers, geographers, geologists and psychologists but also popular among the ordinary people.The aim of study was to determine that how online 3D terrain visualization could be employed using the most appropriate GIS software by finding the applicable web sewer to launch the system.The Virtual Reality Markup Language (VRML) was used as the file format for visualizing 3D terrain in online environments.For that
purpose, two experiments were conducted in these studies. First experiment involved the comparison of VRML output from four different GIS software in terms of terrain visualization quality (bad, acceptable, better) and data
file size (VRML original, VRML compress and image).The technique of 3D terrain draped with satellite imageries
was involved in these experiments.The Arc GIs 9.2 software was found to be the best GIS software which produced promising results with high quality of terrain visualization.Second experiment involved on finding
the best web sewers by comparing four selected web servers at different locations for launching the system online.The Spatial Research Group web sewer which is located close to the testing environment found to be the best.This is because it has the best value and fastest time for most of the tests being done.Therefore, these findings are useful in guiding the developers to choose the most suitable GIS software for developing online 3D terrain visualization.It is also could assists the developers to choose the applicable web sewer for the development of online 3D terrain visualization

Rewriting queries for web searches that use local expressions
Users often enter a local expression to constrain a web search to ageographical place. Current search engines’ capability to deal with expressionssuch as “close to” is, however, limited. This paper presents an approach thatuses topological background knowledge to rewrite queries containing localexpressions in a format better suited to standard search engines. To formalizelocal expressions, the Region Connection Calculus (RCC) is extended byadditional relations, which are related to existing ones by means of compositionrules. The approach is applied to web searches for communities in a part ofSwitzerland which are “close to” a reference place. Results show that queryrewriting significantly improves recall of the searches. When dealing withapprox. 30,000 role assertions, the time required to rewrite queries is in therange of a few seconds. Ways of dealing with a possible decrease ofperformance when operating on a larger knowledge base are discussed

Rendimento de milho em área de integração lavoura-pecuária sob o sistema plantio direto, em presença e ausência de trevo branco, pastejo e nitrogênio Corn yield on no tillage crop-pasture rotation in presence and absence of white clover, grazing and nitrogen
O trabalho experimental foi realizado no campo, na Estação Experimental da Fundação Agrária de Pesquisa Agropecuária (FAPA), em Guarapuava (PR), Brasil, nos anos agrícolas de 1999 e 2000, com o objetivo de verificar a influência da adubação nitrogenada residual na cultura do milho, em Sistema Plantio Direto, cultivado em seqüência, em áreas que no inverno tinham presença e ausência de trevo branco e de animais em pastejo. O delineamento experimental foi o de blocos ao acaso com três repetições. Os tratamentos foram arranjados em parcelas subdivididas. No inverno, nas parcelas, foram aplicados quatro doses de nitrogênio (N-TI = 0, 100, 200 e 300 kg ha-1 de N) e, nas subparcelas, a combinação de presença e ausência de trevo branco e de pastejo (CT = com trevo; ST = sem trevo; CP = com pastejo e SP = sem pastejo). No verão, em cada subparcela proveniente do inverno, foram aplicadas cinco doses de N (N-TV = 0, 60, 120, 180 e 240 kg ha-1 de N), em cobertura, e cultivado o milho. A máxima eficiência técnica de rebrote da cultura de inverno, avaliada dezoito dias após a retirada dos animais, foi obtida com a aplicação de 231 kg ha-1 de N (N-TI). As áreas CP/N-TI apresentaram maiores produtividades do milho que as áreas SP; contudo, estes resultados não foram estatisticamente significativos. As áreas sem N-TI produziram mais milho em subparcelas SP. As parcelas que receberam 300 kg ha-1 de N N-TI não mostraram resposta do milho ao N-TV, comprovando o efeito residual do N-TI. Conclui-se que a interação entre pastejo e N-TI contribui para a nutrição nitrogenada da cultura do milho.<br>This field experiment was carried out at the Fundação Agrária de Pesquisa Agropecuária [Agrarian Foundation for Agricultural and Cattle Research] (FAPA), in Guarapuava, State of Paraná, Brazil, during the growing seasons of 1999 and 2000. The objective was to verify residual effects of nitrogen fertilization on maize crop under a no tillage system, in presence and absence of white clover and grazing animals. The experimental layout was a completely randomized block design with three replications. The treatments were arranged in split-plots. Four N rates (N-TI = 0, 100, 200, and 300 kg ha-1 of N) were previously applied on the main plots during the winter season, while the treatments of the sub-plots consisted in combinations of presence and absence of white clover and grazing (CT = with clover; ST = without clover; CP = with grazing, and SP = without grazing). During the summer each sub-plot that had been prepared during the winter was cultivated with corn which received five N rates (N-TV = 0, 60, 120, 180, and 240 kg ha-1 of N) top dressed. The maximum re-growth efficiency of winter culture plants occurred eighteen days after the animals had been removed from the plots, obtained with 231 kg ha-1 of N (N-TI). The areas CP/N-TI presented higher corn yields than the SP plots, although these differences were not statistically significant. The areas without N-TI produced most in the SP subplots. On plots that had received 300 kg ha-1 of N N-TI there was no response of corn to the N-TV, confirming the residual effect of N-TI. The conclusion was drawn that the interaction between grazing and N-TI contributes to nitrogen nutrition in maize
