Fast computers and powerful data management & graphk software's are indispensable elements of precision farming technology. Activities like yield monitoring and on the go soil sampling provide vast amount of data on the variation in crop and soil conditions throughout the field. The collected data must be processed and reduced into maps to provide serviceable information. The objectives of this study were to develop a software for analyzing the compaction data of a soil excavator and convert it into a colored map. A program was written in C++ language with about 2000 lines and it was evaluated by a simulation method. For testing the software, a force measuring hydro-electronic transducer was designed and fabrkated. By exciting the transducer its output signals were sent to the software which was loaded on a Pentium Pc. Execution of each part of the program follows a flow chart which starts by an icon identifier on the main display. On line progress of the compaction map was visible during the operation period of the transducer. After conduction of each test and making the selevant file, tables of data and functional plot of compaction versus depth at any soil profile is accessible. Results showed that with high confidence, this software could be conjugated on soil compaction scanning. Its facilities seem to be valuable enough to make it as a geographical information system (GIS) software.

Background: Appropriate utilization of primary physician and specialty care. Hs stimulated substantial debate, but the portion of discussion focused on policies that restrict or discourage direct access to specialist. We examined the self-referral incidence rate and the association of health care delivery system structure with utilization of primary physician and specialist.Materials and method: Office visit for patients in private sector and outpatients in public clinic care, stratified by insurance status (Rural Health Insurance, Imam Khomeini Welfare Committee, private insured patients and non insured patients or self-pay patients). 1306 subjects were randomly selected for the study purposes. 39.9% were covered by Imam Khomeini Welfare Committee, 14% Rural Health Insurance. While 46.1%were open for direct referral to specialty services.Results: In Imam Khomeini Welfare Committee closed loop referral system, 6.8% of patients were direct self- referral. In rural health insurance 29.7% of patients were direct self-referral, while in open referral system 75.5% of the patients were direct self-referral to specialist. Significant association was detected between the structure of health care delivery system and patient self- referral to specialty care. The incidence rate of self- referral in public sector was 60.5 and in private sector was 36.4%.Significant association was detected between public and private sector self- referral (P<0.001). Patients' reasons for skipping the general practitioner was high specialist competency as those problems were specific for the specialist, waste of time, friends recommendations and weakness information about referral system.Conclusion: The results suggest greater utilization of specialist in open referral system. Closed loop referral system like Imam Khomeini Welfare Committee may reduce some of these disparities.

The word sign as well as semiotics are considered as one of the important topics in social psychology, linguistics and literature today, which were used and discussed by Charles Sanders Pierce and Ferdinand Desoseur in late nineteenth and early twentieth century. Then it was Jacques Derrida, the French philosoper, who made some criticism towards its outlooks. The present article does not intend to review and criticize all these opinions, rather it tries to clarify that how semiotics can be employed in literary critique and stylization; and the main question of this article is how we can investigate and classify the literary works through semiotics, and how it is possible to find out the evaluation and application of signs in the literary texts.
