Medications are of special importance in the treatment of human and veterinary diseases and the introduction of various types of antibiotics into sewage as well as wastewater has been known as the most important source of antibiotic entry into the environment. The purpose of this study was to evaluate the effectiveness of various parameters on the removal of metronidazole by the advanced oxidation process (H2O2 / MgO) from aqueous media.

This experimental study was carried out in a closed system and the effects of parameters such as pH (11, 9, 7, 5, 3), molar ratios of H2O2 / MgO (5, 3, 1.5, 1), initial concentration of metronidazole mg / L (80, 60, 40, 20), and reaction time (100, 80, 60, 40, 20 minutes) were investigated on the efficiency of metronidazole removal by advanced oxidation process.

The results of this study indicated that the advanced oxidation process (H2O2 / MgO) could remove 84.98% of metronidazole from aqueous media at an optimum pH of 3, a reaction time of 40 minutes, a metronidazole concentration of 20 mg per liter, and a molar ratio of H2O2 / MgO equivalent to 3, while the removal of metronidazole followed first-order kinetics (R2 = 0.958).

The results have shown that the use of advanced refining processes in combination (magnesium oxide nanoparticles in the presence of hydrogen peroxide) can be effective in the removal of metronidazole from aqueous solutions, and the efficiency of removal by this method is inversely correlated with pH and metronidazole concentration, while it shows a direct relationship with exposure time and molar ratio.

Dust deposition phenomenon is one of the most important environmental crisis in places close to desert or dry areas. One of the environmental issues in the eastern regions of Iran is the activity of dust storms and aerosols in the atmosphere of cities. Therefore, this study aims to determine the effects of dust on the prevalence of respiratory diseases among the second-grade high school female students in Zabol City.

In this descriptive-analytic research, 300 female students of the second grade of 5 high schools in the Zabol city were selected randomly in the academic year of 2018-19. Data is collected through demographic and standard respiratory diseases questionnaire and inserted intoSPSS21 software and analyzed via descriptive-analytical statistics.

The results revealed that the prevalence of respiratory diseases and allergy symptoms are higher on stormy daysamong the students (p value < 0.05). Besides, there is a statistically significant correlation between the students' educational level, the presence of respiratory diseases, the Chest pressure and allergy symptoms
(p value < 0.05). The most common respiratory diseases in the mentioned cases are related to year eleven. Moreover, there is a significant relationship between lower grade (or Less GPA) and respiratory distress (p value > 0.05).

Due to the results of this study, most of the students have breathing difficulties on stormy days and the effects of dust were quite clear on them. In addition to the necessity of remedial actions of dust control in the Sistan province, screening and monitoring breathing difficulties among students should be considered in their health control schedule.

The Internet is a strong and multimedia technology that meets the most basic needs of human beings; however, this new technology can have great negative effects on people's lives. The purpose of this study was to investigate the role of Internet addiction on the quality of life of nursing students in Islamic Azad University of Ghaenat.

This study was a descriptive-correlational study. The statistical population consisted of all undergraduate students at the Islamic Azad University of Ghaenat Branch in the academic year of 2018. In order to select the sample group, available sampling method was used and the Yang Internet addiction inventory questionnaire was used for data analysis. The data were analyzed using Pearson correlation analysis with spss-18 software.

The results showed a significant negative correlation between internet addiction (p value < 0.05) and quality of life of students, as well as positive correlation between quality of life (p value < 0.05).

The Internet can relieve a person from everyday life and endangers many of life's homework. Therefore, it is recommended that educational programs be designed to push students towards the proper use of the Internet and scientific sites. The results can be solved by counselors, Psychologists and relevant authorities.

Iodine deficiency disorders (IDD) are the most important epidemic disorders in the world. Goiter is a major public health problem for population living with iodine deficient environments, particularly for young children. In the last two decades, the elimination of IDD has been considered as an integral part of many national nutrition strategies. The aim of current research was to determine urine iodine in elementary students and its relationship with their nutrients intake.

In a cross sectional study 240 students of both genders, aged from
8-10 years were selected from urban and rural area of Zabol city, through cluster random sampling methods. Urine of participants collected and then their urine iodine were determined by digestion methods. Information about nutrients intake gathering by 24 recall method and FFQ questionnaire. Data analyzed by SPSS 19.
P value < 0.05 was considered to be statistically significant.

Out of 240 participants registered in current research 41.7% of them were male and 58.3% were female. The median and mean iodine intake were 104µg and 108.13 ± 21.28 µg respectively. The median and mean of urinary iodine were 10.5 and 13.29 ± 6.95 µg/dl respectively. Mean daily intake of energy, carbohydrate and protein were 2292.58 Kcal, 150.42 and 48.59 gr respectively.

Data analysis showed a significant relationship between urinary iodine concentration and iodine intake (p value < 0.05). Statistical analysis also showed that there was no significant difference between urinary iodine in urban and rural areas (p value = 0.71) and their gender (p value = 0.43).

Professional ethics is a kind of ethical commitment and conscientiousness towards any kind of duty and responsibility. Professional ethics in the educational environment is explicitly and explicitly induced in students' performance. Clinical education was designed and conducted from the perspective of clinical professors and students of Zabol University of Medical Sciences.

In this study, simple random sampling with proportional distribution among clinical students was used and 205 students and clinical professors were surveyed in a census of 60 people. Data gathering tool was Abolghasemzadeh Professional Ethics Questionnaire (2014) Data were analyzed by SPSS software version 19 using frequency, mean and standard deviation indices.

The findings of this study indicate the importance of professional ethics in education, with 60.51% of clinical professors and 51.63% of students agreeing with this issue. In this study, the component of self-sacrifice (73.3%) was observed by professors and the component of observance of social norms (62.9%) was the most observed by clinical faculty members. The empathy component (44.4%) and the respect for others (53.2%) were the least evaluated by clinical faculty members. Statistical tests showed that adherence to all components of professional ethics was strongly evaluated by clinical faculty members.

Adherence to some of the components of professional ethics at a relatively low level Leda recommends that relevant authorities conduct workshops for clinical professors to further promote professional ethics.

It is believed that during pregnancy, it is necessary to have a proper balanced diet to ensure sufficient energy intake for adequate growth of fetus without drawing on mother’s own tissues to maintain her pregnancy. A woman who has been well nourished before conception, begins her pregnancy with reserve of nutrients, so that the needs of fetus can be met without affecting her health. The aim of the study was to assess the knowledge, attitude, and practice of pregnant regarding intake of supplements during pregnancy periods in 2016.

The current research was an analytical and descriptive study. This cross-sectional study was carried out in 2016. The subjects were 280 pregnant women that selected via random cluster sampling method, among whom referred to the health care centers in Zabol city. Data collected using a questionnaire including four parts.

The mean age of pregnant women was 26.1 ± 5.6 years. The knowledge, attitude and practice of pregnant women regarding use of supplement were in medium level (82.3%, 88.8%, and 83.8% respectively). Analysis of data showed a significant relationship between knowledge and attitude of pregnant women about using of supplements during pregnancy periods (p value < 0.05).

Finding showed the knowledge, attitude and practice of pregnant women were in medium levels. However, there is an urgent need to educate and practice about using supplements during pregnancy periods.
