An agent-based intelligent system for information gathering from world wide web environment

To use the vast amount of information efficiently and effectively from Web sites is very important for making informed decisions. There are, however, still many problems that need to be overcome in the information gathering research arena to enable the delivery of relevant information required by users. In this paper, an information gathering system is develop by means of multiple agents to solve those problems. We employed some ideas of Gaia\u27s methodology and an open agent architecture to analyze and design the system. The system consists of a query preprocessing agent, information retrieval agent, information filtering agent, and information management agent. The filtering agent is trained with categorized documents and can provide users with the necessary information. The experimental results show that all agents in the system can work cooperatively to retrieve relevant information from the World Wide Web environment. <br /

Data on Breastfeeding and State Policies in the United States

Breastfeeding is critically important to maternal and child health in the United States. Examining the relationship between breastfeeding outcomes and state policies requires multidisciplinary efforts to link data from various sources. This article describes an integrated dataset that was used to understand the relationship between participation in a nutrition assistance program and low-income children\u27s breastfeeding outcomes [1]. This dataset merged public health information from the National Immunization Surveys Data from 2006 to 2016 and matching state policy data from the Correlates of State Policy Project (CSPP), the U.S. Department of Agriculture/Economic Research Services (USDA/ERS) Supplemental Nutrition Assistance Program (SNAP) Policy Index, the U.S. Bureau of Labor Statistics (BLS), Centers for Medicare & Medicaid Services (CMS), and the Census Bureau. The integrated dataset compiles variables in breastfeeding outcome, child\u27s and mother\u27s socio-demographic characteristics, and state-level policy measures, including SNAP participation rates, SNAP policy indices, unemployment rates, and Children\u27s Health Insurance Program (CHIP) enrollment rates. This multidisciplinary dataset included information on a total of 219,904 children with 98 variables

Motion State of Fuel within Shell in Projection Acceleration Process

The fuel-air explosive (FAE) warheads are charged with the liquid-solid mixture fuel. The fuel is different 'om conventional solid explosives in physical and mechanical properties. The mass centre of the charged fuel changes during projecting the projectile. In this study, a method to calculate the mass centre change of the charged fuel is suggested and the  influence of this change on the projectile motion state in the projection process is discussed. The results show that in projection, the fuel mass centre varies with the projection acceleration and the deformation characteristics of the mixture fuel. The higher is the acceleration, the larger is the displacement of the mass centre. This displacement also increases with the compressibility of the fuel. It constitutes an influence on the state of motion for the whole projectile in the projection process, whose calculation approach is also proposed. The result provides a theoretical basis for the design of the FAE weapons

Disparities in Caregiver-Reported Dental Cavities and Toothaches Among Children in the Special Supplemental Nutrition for Women, Infants, and Children (WIC) Program

Purpose: Dental caries is prevalent among low-income and minority children despite oral health promotion programs. The purpose of this study was to examine disparities associated with caregiver-reported cavities and toothaches among children in the United States aged 2-4 years by their eligibility for and participation in the Special Supplemental Nutrition for Women, Infants, and Children (WIC) program. Methods: A secondary data analysis was performed using the 2016 National Survey of Children\u27s Health (NSCH) data on children aged 2-4 years (n=7,719) with complete WIC participation information. Three groups were formed based on WIC eligibility and participation status: WIC participants, income-eligible non-participants, and higher-income non-participants. Caregiver-reported cavities and toothaches were compared by WIC eligibility and participation using chi-square tests and multivariate logistic regression analysis. Results: Among all children in the data set, 2,069 were WIC eligible, 49.8% of whom participated in WIC. Participants in WIC had higher reported cavities and toothaches (10.0% and 5.2%) than income-eligible, or higher-income non-WIC participating children (8.9% and 3.2%; 4.4% and 0.1%, respectively; p \u3c 0.001). However, non-Hispanic, white WIC participants, had a higher proportion of reported cavities (14.0%) and toothaches (8.2%) than income-eligible nonparticipants (6.7% and 1.9%, respectively; p \u3c 0.05). While non-Hispanic, black WIC participating children, had nearly 3.6 times more reported cavities than income-eligible nonparticipants (9.0% vs. 2.5%, p \u3c 0.05). Conclusion: Caregiver-reported cavities and toothaches varied by sociodemographic characteristics within WIC participation and eligibility groups. These findings suggest that more research is warranted to explore factors that are contributing to oral health disparities associated with WIC eligibility and participation
