With the development of society and the progress of science and technology, the agricultural engineering information grows fast. For this, this paper takes agricultural engineering information system as the object, analyzes the agricultural engineering information system by SWOT analysis method. Then proposed the countermeasure of establish agricultural engineering information system operation mechanism.

Highmark Medicare Services, Inc. (Highmark) is a Medicare Administrative Contractor (MAC) under contract with CMS to administer the Medicare Part A (hospital insurance) program. Highmark administers the program for MAC Jurisdiction 12, which consists offour StatesPennsylvania, Maryland, New Jersey, and Delaware-and the District of Columbia. For fiscal year (FY) ended 2006, 133 hospitals in MAC Jurisdiction 12 collected and reported information to the IRIS on residents. In FY ended 2007, the figure was 132 hospitals. National Government Services, Inc. (NGS) is a MAC under contract with CMS to administer the Medicare Part A program for MAC Jurisdiction 13, which consists oftwo States-New York and Connecticut. For FY ended 2006, 139 hospitals in MAC Jurisdiction 13 collected and reported information to the IRIS on residents. In FY ended 2007, the figure was 137 hospitals. The objective of our review was to determine whether hospitals in MAC Jurisdiction 12 claimed Medicare GME reimbursement for residents also claimed by hospitals in MAC Jurisdiction 13 in accordance with Federal requirements.

This report describes the architecture, functionality and the field demonstration of a newly developed dedicated short??range communication (DSRC)-based Vehicle to Infrastructure (V2I) communication system for improving traffic efficiency and safety in the work-zone related congestion buildup on US roadways. The goal was to develop a portable system that can be easily deployed at a work zone site to acquire and communicate important travel information, e.g., travel time (TT) and start of congestion (SoC) location to the driver. By providing this information, i.e., SoC location and TT, drivers can make informed decisions on route choice and be prepared for upcoming congestion. The system is composed of a portable road-side unit (RSU) that can engage the on board units (OBUs) of the traveling vehicles using DSRC technology to acquire necessary traffic data (speed, time, and location). From the acquired data, the RSU periodically estimates the SoC location and TT that are broadcast to all vehicles in its coverage range. An OBU receiving the broadcast message calculates the distance to the SoC location. The distance to the SoC location and TT are then relayed to the driver, who can make smart decisions regarding whether to seek an alternate route and when to expect a sudden speed reduction. Results from the field demonstration have shown that the developed system can adapt to changing work-zone environments smoothly under various congestion patterns on the road.

The purpose of this toxicological review is to provide scientific support and rationale for the hazard and dose-response assessment in IRIS pertaining to chronic exposure to tetrahydrofuran. It is not intended to be a comprehensive treatise on the chemical or toxicological nature of tetrahydrofuran. The intent of Section 6, Major Conclusions in the Characterization of Hazard and Dose Response, is to present the major conclusions reached in the derivation of the reference dose, reference concentration and cancer assessment, where applicable, and to characterize the overall confidence in the quantitative and qualitative aspects of hazard and dose response by addressing the quality of data and related uncertainties. The discussion is intended to convey the limitations of the assessment and to aid and guide the risk assessor in the ensuing steps of the risk assessment process.

The drainage basin is a fundamental hydrologic entity used for studies of surface-water resources and during planning of water-related projects. Numeric drainage areas published by the U.S. Geological Survey water science centers in Annual Water Data Reports and on the National Water Information Systems (NWIS) Web site are still primarily derived from hard-copy sources and by manual delineation of polygonal basin areas on paper topographic map sheets. To expedite numeric drainage area determinations, the Colorado Water Science Center developed a digital database structure and a delineation methodology based on the hydrologic unit boundaries in the National Watershed Boundary Dataset. This report describes the digital database architecture and delineation methodology and also presents the results of a comparison of the numeric drainage areas derived using this digital methodology with those derived using traditional, non-digital methods.

This project conducted a thorough review of the existing Pavement Management Information System (PMIS) database, performance models, needs estimates, utility curves, and scores calculations, as well as a review of District practices concerning the three broad pavement types, asphalt concrete pavement, jointed concrete pavement, and continutously reinforced concrete pavement. The proposed updates to the performance models, utility curves, and decisions trees are intended to improve PMIS scores and needs estimates so that they more accurately reflect District opinions and practices, and reduce performance prediction errors. Reseachers hope that implementation of these PMIS modifications will improve its effectiveness as a decision-aid tool for the Districts. Appendices H, J, and K contain calibrated PMIS performance model coefficients for asphalt concrete pavement (ACP), continuously reinforced concrete pavement (CRCP), and jointed concrete pavement (JCP), respectively; they are recommended for use in the existing PMIS performance models (summarized in Chapter 4). Appendices M and N contain new revised utility curves and coefficients for ACP, CRCP, and JCP pavement distresses. Appendices T, U, and V contain revised ACP, CRCP, and JCP decision trees for needs estimates determination. Appendix Z contains a recommended priority index that can be used for programming projects for preservation, rehabilitation, and reconstruction.
