Introduction. In recent decades, the figures of diseases and their related factors have been changed from infections disease to chronic ones. In this regards, the relation between improper nutrition models and non-infectious disease such as CVD, Cancers, and Diabetes has been diagnosed. This study examines to determine KAP of nutrition and food models by Sepah formal personnel.Materials and Methods. This is descriptive study through a Cross-sectional method, conducted on 425 formal personnel of a military populations including 393 men and 32 women with and age range of 19-65 years drawn by simple random sampling. To determine the subjects, KAP, a Researcher made questionnaire was used. The validity of the questionnaire was confiremed by experts. The collected data has been analyzed using the SPSS14. Three different levels, low, middle, and good was defined for KAP categorizing.Results. The mean of scores for knowledge, attitudes, and practice of nutrition by personnel was reported 63.1, 73.1, and 38.3 respectively. In knowledge domain, only 14.3% of the subject, more than 60% of the study population had a good attitude toward the issue. This percentage for the practical domain was reported only 0.2%. That is, the majority of the subjects (60.5%) has a desirable view and attitude toward the issue, and a positive powerful association has been proved between knowledge and attitudes toward food models by the subjects (r= 0.71). The association between knowledge and practice, however, was not statistically significant (r=0.303). In addition, subjects with academic levels of education have more knowledge about the issue than uneducated subjects (p<0.009). Based on the findings of the study, air forced personnel got more grade than other force in both knowledge and attitude domains (p<0.001).Conclusion. The findings of the study indicate that in spite of having good and desirable knowledge about the issue by the subjects, their attitude and practices were not acceptable. Thus, planning a educating them with regards the food and nutritional models through various for improving their nutritional status is recommended.

Introduction. Giardia, a flagellate protozoan, is a sort of intestinal parasite in human and animal bodies. Despite of man-to-man conventional method of transferring, this parasite is one of the main causes of water born diseases, and addition of conventional rates of chlorine to water cannot remove it. Ozone is an excellent disinfectant and can inactivate the most resistant microorganisms. It is used periodically to disinfect drinking water. The aim of this study is to evaluate the rate of ozone used for removal of giardia cysts in water.Material and Methods. This is an experimental study and corona discharge method is used to generate ozone. Giardia cysts were separated by concentration density slope with sucrose, counted 10 times with Thoma lam and then the mean was calculated. This solution, containing 120,000 cysts/lit, was ozonated in 5, 7 and 9 min with the density of 1.3 mg/lit in city water, distillated water and physiology serum. In another test, the effect of elapsed time on ressistance of giardia cyst was evaluated for a 6-day period, in the first, 3rd and the 6th day for various minutes of 1, 3, 5, 7 and 9 with the density of 2 mg/lit in the city water.Results. Durations of 5 and 7 minutes could not remove all of the cysts, but after ozonation for 9 minutes, all of the cysts were removed. When tests were performed in distillated water and physiology serum, all of the cysts were removed completely. In another test, all of the cysts were removed in the durations of 7 and 9 minutes of the first day, while in the third and the sixth day, the efficiency of cyst removal rate decrease in the 7 and 9 minutes and fresh cysts were observed.Conclusion. Distillated water and physiology serum caused disturbance in the test and resulted in incorrect data, so decolorized city water is used in this pilot study. As time elapsed, environmental conditions caused difficulties for cyst life continuing. Cyst's cell wall gets resistant and removal of all of giardia cysts with first day Ct is impossible.

Introduction. Health care worker always are in risk of injury with sharp devices that can be a risk factor for HIV, HBV, HCV and other blood borne pathogen. Nurses experience the most injuries from sharp devices. Severity and fatality consequences of such exposure and limitation of effective treatment result in preventive planning. Therefore we design this study to evaluation of needle stick prevalence in nurses of a military hospital and investigate the risk factors.Material and Methods. In this descriptive cross sectional study, we used a two-page questionnaire. At the time of the survey 613 nurses were employed in this military hospital. The questionnaire include sections for demographic items (such as age, sex and years of experience), type of device that caused the injury, the event that lead to the NSI, and whether the event was reported. We also asked the location where the NSI occurred. The survey instrument was distributed and collected during October 2007.We used SPSS version 12 for evaluation of collected data.Results. Of 613 nurses occupied, 201 nurses were been needle sticked (32.78), 107 nurses were male (53.2) and 94 female (46.8) average age in time of N.S was 34 (SD: ± 6.5). in education level in 15 nurses was "kardan" (7.5%) and 178 nurses was license (88.6) and 8 nurses were in level of master of sciences. Needle of syringe was most common for N.S percent of 70.6% (142 cases). Blood sampling was most action for N.S with 49 cases (24.4%). The most common organ that injured was the second right hand finger with 60 cases (32.8%). The most common time of injuries was in morning shift. Conclusion. High rate of N.S and occupational exposure with Blood is a alarm for nurses, there for in field education and informing for reporting the all person who needle sticked.

many factors such as a diabetes, hypertension, hyper lipidemia, smoking and occupational stress are in association with atherosclerosis. Up to now there isnt and study about risk factor differences between military occupation and non millenarian. Therefore we designed this study to investigate these differences.

in this cross-sectional study all patient had angiography, angioplasty or CABG in year of may 2006 to may 2008 in Baqiyatallah or Shahid rajaee hospital were investigated. We collect data by face to face questionnaire based material. Our variable include age, sex, smoking, hyper lipidemia, diabetes, psychological history, chemical weapons exposure, first line standing.Results. form 196 patient referred to Baqiyatallah and Shahid rejaee 2 patient were excluded, from 194 left, 132 (68%) were non military and 62 (32%) had military occupation. average age of CABG was 51.5 in miltaries and 57.5 in non militaries hypertension and diabetes were more common in non military occupation and smoking and psychological histories were more common in military occupation. All patent undergo CABG were male.Conclusion. in patient undergo CABG and who had chemical weapons exposure hand less average age that maybe because of military occupation and its occupational life style or because of exposure with chemical weapons that result in cardiovascular disease in lower age.
