Abstract
Background: Health literacy (HL) is the capacity to obtain, process, and understand basic health information and the required services to make proper health decisions, which empowers the individuals to perform self-care behaviors. This study aimed to determine the relationship between health literacy and self-care in patients with type 2 diabetes. Methods: This cross-sectional study was conducted on 390 patients who referred to rural health centers with type 2 diabetes in Babol, Iran, during 2017. The data were collected using Health Literacy for Iranian Adults and the Summary of Diabetes Self-Care Activities. Furthermore, the data were analyzed in SPSS software (version 20) through one-way ANOVA, t-test, and Pearson correlation coefficient.
Findings: According to the results, the mean±SD HL of the patients was 48.56±16.31. Moreover, the results revealed that 55.9% of the patients had an inadequate level of HL. Moreover, the mean±SD of self-care score was obtained at 50.77±15.18 in one week. The results also revealed no significant relationship between HL and self-care behavior (P=0.064). However, HL was significantly correlated with gender, age, marital status, educational level, occupational status, socioeconomic status, and disease duration (P<0.05). Furthermore, self-care behavior was significantly correlated with the number of family members, educational level, and disease duration (P<0.05).
Conclusion: Given that over 50% of the patients have an inadequate level of HL, and considering that demographic characteristics play an important role in HL and performing self-care behavior, it is suggested that health care providers include these issues while developing healthcare programs.

Abstract
Background: Despite its significant impact on the global economy, the iron and steel industry is also the largest consumer of energy and leaves behind a significant environmental footprint. Iran is also one of the top 10 steel producing countries, with more than 77% of its steel being produced in electric arc furnaces (EAFs). Therefore, a proper environmental assessment should be done to minimize the negative effects on the environment. The purpose of this study was to evaluate the life cycle of steel production using EAF method in Iran. This study identifies the major processes and inputs that affect the environmental impact of steel production and proposes effective methods to prevent pollution.
Methods: In this study, SimaPro software with ecoinvent database and IMPACT 2002+ evaluation method were used. Life cycle inventory data were obtained from the average performance of factories in one year and the functional unit was considered to be one ton of rolled steel (coil).
Findings: Among different categories of environmental impacts, non-renewable energy, global warming, and inhalation of mineral particles had the most significant threat, respectively, so that these three categories included 86.5% of the total environmental impact. Among several processes, the greatest effects were related to EAFs (35%), followed by sponge iron production (28.9%) and pellet production (17.1%) in second and third places, respectively. The highest environmental impacts of input materials included electricity (33.8%) and gas consumption (25.8%), respectively.
Conclusion: Despite significant advances in iron and steel industries in recent decades, they still have high energy consumption and carbon dioxide emissions. Conducting a life cycle assessment allows steel producers to identify the most polluting processes in order to make the necessary plans to improve them.

Abstract
Background: Since sponge iron is the main feed of steel furnaces for the production of crude steel, especially in electric arc furnaces, the production of quality sponge iron is one of the concerns of the steel industry. The reduction process, which is the conversion of pellets into sponge iron using reduction gases, has been used in Iran for many years. Therefore, there is a necessity for a proper environmental assessment to reach the minimum level of negative impact on the environment. This study aims to investigate the environmental impacts of sponge iron production by Midrex method using natural gas and to compare the effects associated with different production processes. This paper identifies the processes and significant inputs that affect the environmental impact of sponge iron production and proposes effective methods to diminish contamination.
Methods: The OpenLCA software with the Ecoinvent database was used by using IMPACT 2002+ evaluation method. Life cycle inventory data were obtained from the average performance of factories in one year, and 1 ton of produced sponge iron was considered as the functional unit.
Findings: Among different types of environmental impacts, non-renewable energy, mineral particle respiration, and global warming had the most significant effects, respectively. These three categories of impact together accounted for about 87.5% of the total environmental impact of the whole process. Among the processes, the greatest impacts were related to the production of sponge iron (62.8%), followed by the pellet production process (37.8%), and the greatest environmental impacts of input materials were related to natural gas (44.3%) and iron ore (23.9%), respectively.
Conclusion: Despite significant advances in sponge iron industries in recent decades, they still have high energy consumption as well as mineral particles and carbon dioxide emissions. Conducting a life cycle assessment allows producers to identify the most polluting processes in order to make the necessary plans to improve them.
