Colorectal cancer is a global health problem, but most of these patients are curable through early diagnosis. The present study aimed to investigate the effect of an educational intervention through a campaign on health anxiety and participation of middle-aged people (ages 50-70 years) in CRC screening based on the Health Belief Model in urban areas.

A quasi-experimental study was conducted on 390 people in age range 50-70 years in Parsian in 2021. The participants were selected using convenience sampling. Champion’s Health Belief Model Scale and Health Anxiety Questionnaire were used to collect data. The educational intervention was carried out in the form of a campaign through educational video clips and a banner for four weeks. Data analysis was done in SPSS 26 software using descriptive statistics and univariate analysis of covariance.

There was a significant difference between the intervention and control groups in terms of the mean scores of the Health Belief Model scale (knowledge, perceived severity, perceived sensitivity, perceived benefits, perceived barriers, perceived self-efficacy, and action guide) and the health anxiety questionnaire (consequences of disease and probability of disease) after the intervention (p<0.001).

The constructs of the Health Belief Model are good determinants of the action of high-risk individuals to undergo fecal occult blood testing. This highlights the necessity of implementing comprehensive educational programs focusing on the constructs of the Health Belief Model in this population.

Plastics are the most important pollutants in oceans and seas and are regarded as serious threat to aquatic ecosystems. The effect of tide, wind and water depth on movement of plastic marine debris has been examined in north of Hormuz Strait in Hormozgan province coasts, Hormuz Island and east of Qeshm Island. Particle tracking is used by numerical modeling using MIKE software for time interval of January to March 2017. Field study and model output clarified that direction of the particle movement during a tidal period made an elliptical shape that the small diameter formed due to wind and the large diameter varied with tide motion. The highest movement of the particle was observed one hour after high water (low water) to one hour before low water (high water). Wind was the most effective parameter within one hour before and after low water (high water). At same the time interval, as the area deepened, more movement was observed. Tracking the samples showed that more than 60% reached Bandar Abbas coasts in less than 8 days after release. The other regions receiving the samples were coasts of Hormuz Island and East of Qeshm Island with estimates of 30% and 2%, respectively. The results can be used to forecast marine macro debris accumulation zones and time duration which assist the management system as a cleanup tool.

In the current research in order to recognition and explaination of operational strategies compilation components of I.R.I.Navy through achieving marine authority, in addition to the exploration study, deep interviews with genius people, the state and military authorities, there were field studies (by considering the country's south east given responsibility) and also taking into account the geopolitics situation, threats (military and non-military), Iran Navy approach and related upper hand documents study, we have tried to step forward in research goals and response to the questions and approving research hypothesis based on identification and definition of operational strategies compilation components of I.R.I.Navy through achieving marine authority. Also the output of this paper could be a road map to form organizations and equipments related to the operational needs of Iran navy through country's marine power and to be an efficient step in theoretical operational strategies explanation of the I.R.I.Navy. According to the surveys from a thirty-nine statistical society selected by objective sampling method and using content analyzing and data description method, a final questionnaire has distributed among statistical society members after measuring and crediting tools explanations. By analyzing and interpreting of the output data, four main components should be considered: principle component, strategic policies and documents (by six factors), the main component of internal environment of I.R.I.Navy (by nine factors), the operational scene of international forces (by six factors), and finally the main component of operational area situation (by five factors).
