Dust phenomenon is one of the most harmful disasters that has caused a lot of problems in different parts of the world. In Iran, the Zabol area is heavily influenced by this phenomenon. Therefore, the necessity of conducting research on the effects of these effects on the health of people is necessary. Therefore, the purpose of this study is to investigate the effects of dust on mental health of students in Zabol University of Medical Sciences. A descriptive-analytic study was conducted in Zabol University of Medical Sciences during the period of 2018-2019. In this study, a sample of 320 students was selected randomly. To collect data on the effects of dust on Students' mental health was a researcher-made questionnaire with 27 questions using the Likert scale method. The validity of the questionnaire was performed by multi-expert opinion and reliability was calculated with Cronbach's alpha coefficient of 92%. About 82% of the participants were indigenous people of Zabol city and 17.8% of them were non-native. The mean and standard deviation of mental health score were 70.89 ± 12.44 in gairls and 72.38 ± 12.54 in boys. About 73% of the subjects had moderate mental health and 6.6% had mild health and about 20% had no mental health. Mental health at undergraduate level was better than other levels, but there was no relationship between mental health and other variables. Psychological issues are factors that may be more frequent with the subsequent occurrence of dust. During the dusty phenomenon, people are at risk and suffer from stress. Also, the tolerance threshold may decrease and cause aggression and anger, so the authorities should In order to make the students happy, they should provide facilities for exposure to dust and provide students with the necessary training on health and safety issues.

Antibiotics, due to cumulative properties, cause major problems in humans and the environment. The purpose of this study was to evaluate the effect of zinc oxide nanoparticles (ZnO) to remove antibiotics ciprofloxacin from aqueous solutions. In this experimental study, the effect of parameters such as solution pH, antibiotic concentration, contact time and dose of nanoparticles in antibiotic degradation of ciprofloxacin was investigated. At each step, keep parameters constant and variable of one parameter, test was done. The results of the experiment showed that the initial pH of the solution in the antibiotic removal process is the main parameter. And the optimum pH value was 7. The removal value at this pH is 93/53%. Also, the contact time parameters were obtained at 93/55% and the nanoparticle dosage at 0.01 g / l was equal to 92.66%. The results of the experiment showed that the use of ZnO nanoparticle in the antibiotic removal of ciprofloxacin is effective.

Staphylococcus aureus (S. aureus) is one of the most important etiological agents of Blood stream infections, urinary tract infections and respiratory tract infections. Rapid and precise typing of S. aureus is a prerequisite for epidemiological surveillance and controlling of infection caused by this bacterium. Therefore, the aim of the present study was to determine different biotypes of S. aureus isolated from nasal cavity of Amir-almomenin hospital health care workers. In this study, a total of 278 nasal swabs were collected. The isolates were identified using conventional microbiology tests. Finally, biotypes were determined by standard biotyping methods. Of 278 collected samples, 31 (11%) were known as nasal carriage of S. aureus. Based on the biotyping methods, 19% of isolates belonged to human ecovars, while 45% and 29% of isolates were classified as bovine and ovine ecovars, respectively. Meanwhile, 6% of isolates were found to be non-host specific (NHS) biotypes by this method. The results of the present study showed that in studied hospital, healthcare staff samples were frequently contaminated by strains belonging to various ecovars. However, among host specific (HS) biotypes, bovine ecovar was the most common biotype. The results show that different ecovars can be transmitted between various hosts.

New approaches to learning based on learning and learning are aimed at facilitating the learning process and ultimately promoting academic achievement, and since students have a large volume of content during their studies, the lack of a choice of methodology leads to confusion, this study aimed to identify student’s in Zabol Univercity of Sciences study habits and its relationship with academic performance was performed. In this cross-sectional study, 313 students were selected by random sampling method in Zabol University of Medical Sciences (2019). Data was collected using study habits questionnaire (PSSHI) that has 45 questions in eight areas. In order to measure academic performance, the mean of total score was used. Data were analyzed by descriptive and inferential statistics. The mean and standard deviation of reading habit score in female students was 122.22 ± 29.58 and male students were 119.47 ± 28.27. 28.1% of students were inappropriate study habits, 67.7% had moderate study habits and 4.2% had appropriate study habits. There was no significant relationship between the mean score of study habits and their academic performance. Also, there was no meaningful relationship between the study habits of people with academic term, gender, marital status, employment status, educational level, place of residence. There was a meaningful and reverse relationship between the habit of studying and age and there was also a significant relationship between the habit of study and the field of study. In general, student’s study habits are in moderate grade and can say that the study method in students have not a good quality. On the other hand, due to the significant relationship between study habits and academic performance, pay attention to this issue is considered necessary by the faculty education authorities. Holding training courses, in this regard can be effective in improving student learning process.
