Emerging noncommunicable diseases (NCDs) with premature mortality are one of the major concerns in health supervising organizations of the world. High intake of energy, salt, sugar, fat, and trans fatty acids are introduced as dietary risk factors of NCDs. The status of food risk factors is presented in Traffic Light (TL) food labeling through colors of red, yellow, and green as the signs of stop, wait and watch and go, respectively. This stepwise interventional study examined whether TL education can result in choosing healthier food via assessing the impact of face-to-face educational sessions on knowledge, attitudes, and practices of 673 respondents toward TL food labeling through a self-administered and structured questionnaire. Paired t test or alternatively Wilcoxon test was used to evaluate the influence of education in total scores of knowledge, attitudes, and practices in test–retest. Results indicated that before education, the average of the scores for the knowledge, attitudes, and practices was 1.003 ± 0.69, 10.97 ± 1.86, and 1.60 ± 1.84, respectively. After education, the scores were increased to 8.72 ± 3.11, 15.95 ± 2.64, and 8.42 ± 1.69. Significant differences in the scores of the respondents were observed before and after education ( p < .05). This study revealed that the intervention of education had positive effect on the knowledge, attitudes, and practices of the studied population. Even though general awareness about the food risk factors of NCDs existed, special education is required to make public TL and food labeling information usage as an actual guidance for every food item in Iran.

Breast cancer is the second leading cause of death after lung cancer. The only possible way to save patients' lives is early diagnosis of the disease; Because if this disease is diagnosed in the early stages and with a high level of accuracy, the chance of survival increases. Different fuzzy-based soft computing techniques have been proposed. In this research, the proposed fuzzy hybrid algorithm -particle swarm has been used to detect the type of breast tumors based on the analysis of features in mammography images. The proposed method in this study, the fuzzy hybrid algorithm -the proposed particle swarm algorithm, has a remarkable performance of 94.58% in breast cancer diagnosis. The results obtained from this study can be used for timely diagnosis and providing effective treatments for breast cancer.

The purpose of the present study was to investigate the predictive contribution of attitude to life and belief system on self-resilience and psychological toughness of cancer patients about the mediating role of emotion regulation. The current research is fundamental in terms of its purpose and descriptive of correlation type in terms of method. The statistical population consists of all cancer patients of Shahinshahr city. The sample size was 150 people based on Cochran's formula and the country's corona situation. The sampling method of the current research is available. This research used tools of attitude to life, belief system, self-resilience, psychological toughness, and emotion regulation, all of which had acceptable reliability and validity. The research data was done in two parts, descriptive and inferential, with the help of Excel, SPSS, and SmartPLS software. The results showed that the attitude towards life and the belief system with the role of mediating emotion regulation has a significant predictive ability on the self-resilience of cancer patients. Also, attitude towards life and belief systems with the role of mediating emotion regulation can predict the psychological toughness of cancer patients. In addition, emotional regulation has a significant relationship with self-resilience and psychological toughness. According to the research results, it can be concluded that the attitude towards life and the belief system mediating emotion regulation can predict cancer patients' resilience and psychological toughness. Also, the attitude toward life and the belief system directly impacts. In addition, attitude towards life has a direct positive relationship with psychological toughness.
