Abstract
The start of this survey, 588 students (294 in either area) were selected randomly but the ultimate size of the sample was increased to 905, allowing for a 35% omission rate. Anthropometric measurements and stool examinations were performed. Questionnaires dealing with socioeconomic status were completed through interviews with mothers. We also carried out blood tests on a subsample of 180 individuals (1/5 of the the original sample).The results of the study were as follows:In Area 1:4.3% and 15% of the subjects showed evidence of anemia and parasites, respectively.Th mean hemoglobin and hematocrit concentrations were 13.46 g/dland40%.Anthropometric assessment revealed rates of 8.6% and 1.3% for severe wasting and obesity, and 11.9% for severe stunting. Gauging the weight-for-age index on standard growth charts, 13.1% of the subjects had severe wasting and 14.4% suffered from severe stunting and based on BMI, 21.3% were severely malnourished.ln Area 2:5.8% and 13% of the subjects suffered from anemia and parasites, respectively.Mean hemoglobin and hematocrit concentrations were 13.05 g/dl and 37.8%.Anthropometric assessment showed that 9% of the subjects had severe wasting, and 1.8% were obese. 11.7% showed severe stunting. On standard growth charts, 12.4% had severe wasting and 15.3% were severely stunted. Judging by the Body Mass Index, 21.6%) of the subject had severe malnutrition.The mean weight, height and BMI in both areas were substandard and the mean weight in Area 1 was lower than in Area 2. Statistical Associations:In Area 1: the following variables showed statistically significant relationships: History of parasite infection in the last year with child's weight for age. Mother's age and history of maternal parasite infection in the fast year with child's height for age.Parasites infection in the last year with BMI.In Area 2: statistically significant relationships were found:Between mother's literacy / mother's job /family income and child's weight for age.Between family income / percentage of income spent on food/ current parasite infection and height for age.Between diseases affecting food intake and BMI.

Abstract
Background and Aim: In the raw furniture preparation workshops, in which the workers usually have an undesirable postures when at work, ergonomic assessment and the work environment improvement seem essential. Developing checklists and calculating ergonomic indices would be useful in this assessment. This study was conducted with the objectives of assessing musculoskeletal disorders (MSDs) risk factors and determining types of corrective measures in raw furniture preparation workshops.
Materials and methods: After conducting task analysis, 268 workers were assessed using an ergonomic checklist developed for the purpose and ergonomic indices were calculated. The Nordic musculoskeletal disorders questionnaire was used to determine the prevalence rate of MSDs among the workers. Data were analyzed using the t-test and the test of proportions.
Results: The highest prevalence was in the lower back (38.4%) and the knees 36.2%). Statistical analysis revealed that there were significant associations between MSDs and calculated ergonomic indices (p<0.001). In addition, calculation of OR revealed that ergonomic conditions were associated with MSDs in different body parts (OR=2.90-9.49, p<0.001). On the whole, the working conditions of 32.46% of the workers studied were poor from an ergonomic point of view.
Conclusion: The checklist developed was found to be an appropriate and low-cost tool for ergonomic assessment. The most important problems in the workshops were due to inappropriate general working conditions, inappropriate organization, and unsuitable work stations.

Abstract
Background and Aim: Vitamin D deficiency is highly prevalent in Asia, including the Middle East. Vitamin D deficiency has been found to have an inverse relationship with occurrence of type-2 diabetes mellitus (DM). In this study we assessed the vitamin D and calcium status in type-2 diabetic patients and compared it with that of healthy subjects in Tehran, Iran.
Materials and Methods: This cross-sectional study included 180 Tehrani individuals, including 95 DM patients, selected randomly from among the members of Iranian Diabetes Association, and 85 healthy subjects in Tehran, Iran. Age and gender were adjusted between the two groups. Serum levels of 25(OH)-vitamin D, calcium, phosphorous, and Parathormone (PTH), as well as weight, height and body mass index (BMI) were measured.
Results: The mean and SD age and BMI of the diabetic patients were 51.26 ± 11.18 years and 26.22 ± 9.30 kg/m2, respectively the corresponding figures for the healthy subjects were 51.55 ± 13.39 and 26.26 ± 4.55. The prevalence of calcium deficiency was close in the 2 groups, it being 55.8% in the diabetic, and 57.0% in the healthy, subjects. The data also showed that while 26.3% of the patients suffered from a poor vitamin D status, only 18.6% of the healthy subjects had this problem.
Conclusion: Vitamin D deficiency is highly prevalent among both type-2 diabetic and healthy subjects and should be considered a public health and nutritional problem in Tehran city, Iran.

Abstract
Background and Aim: Measuring the hand's grip strength and comparing it with its normative data is a valid method for detecting intensity of the numerous damages of hand. In addition, co mparing grip strength of people in different regions can reveal hidden facts resulting from genetic and environmental factors . Therefore , the present study was carried out with the aim of comparing grip strengths and three types of pinch (tip, key and palmar) strengths of healthy people living in five Iranian cities and determining normative data of grip strengths of citizens of these cities.
Materials and Methods: This was an applied cross-sectional study. The study population included 1008 healthy adults (526 males and 482 females) from the Fars (Persian) ethnic populations in five cities of Iran ( Mashhad, Isfahan, Shiraz , Kerman and Yazd ). The American Society of Hand Therapists (ASHT) recommendations were followed to establish normative data of grip and pinch strengths . Jamar dynamometer and Seahan pinch gauge were used to measure grip and pinch strengths. In addition, the effect of body mass index (BMI) and other anthropometric variables (hand length, height and weight) on grip strengths was assesed.
Results: In the present study, no significant differences were found between grip and pinch strengths of adults in the five cities. From among the parameters studied , height and hand length had the most influence on the grip strengths .
Conclusion: The findings of this study show that populations of any particlular ethnic group have similar grip strength despite living in different geographical areas. The normative data of grip strength obtained in this study are important for ergonomists helping them to optimize work programs and designing tools, as well as for therapists helping them to reach the goals of treatment, assessing the body response to medical treatment, and detecting good function of the upper extremities .

Abstract
Backgrond and Aim: Demodicosis is a common skin disease. Great number of admissions to the clinics is occurring in the country. Regarding the high prevalence of this parasitic arthropod, investigating on pathogenesis, route of transmission and the complications they may produce, is considered of great importance. Generally, demodex parasites often exist in the skin tissue and tend to live in the face specifically in cheeks, forehead and nose, where sebum excretion is active and may provide a favorable habitat for living and breading the parasite. Diagnosis is carried out during an exploratory skin test for a cne, pityriasis rosacea and ophthalmic infectious diseases such as blepharitis. Determination of their biological role in chronicity of general skin disorders is an interesting topic in research.
Materials and Methods: Patients were admitted to the Razi hospital, Research Center for skin diseases and leprosy, and three other clinical laboratories considered for assays. The questionnaire was filled for each patient and the sample was taken from the affected area. Ecto parasites were transferred to the potassium chloride solution 10% and studied under a light microscope.
Results: A total of 100 patients were studied, from which 78 patients were diagnosed as infected with the Demodex folliculorum. Of these, (%92) were female and (%7.6) male (p <0.05). The highest frequency was observed in the age group 41 to 50 years (P <0.05).
Conclusion: In this study, the relative frequency of demodicosis was more common in women and in the middle-aged group. Generally this high level of frequency will intensify the necessity of the identification of parasites and its pathological effects in chronic infectious diseases.

Abstract
Background and Aim: Candida albicans, the most common human fungal commensal pathogen, is a normal member of the human microbiota which can colonize the oral cavity, vagina and gastrointestinal tract. This opportunistic pathogen can cause diseases ranging from mucosal infections to systemic mycoses, depending on the vulnerability and weakness of the immune system of the host. In addition, it is the most common cause of septicemia with 50-100% mortality. Ultraviolet-B (UV-B) radiation is an electromagnetic radiation with a wavelength of 100-400 nm. It reduces the synthesis of proteins and nucleic acids, retards growth, and causes mutation in eukaryotic and prokaryotic cells. Previous investigators have reported on the different effects of UV irradiation on Candida albicans including cidal effect, inhibitory growth, as well as phenotype switching. In the present study we investigated the effect of UV-B irradiation on C. albicans’s growth in a solid medium, production of chlamydoconidia, carbohydrate assimilation and pathogenesis in mice.
Material and Methods: C. albicans was grown in a SC medium, followed by incubation at 30° C for 24 hours and irradiating the cells with UV-B for 5,10,15,20 min at 302 nm wavelength by transilluminator. A sample of non-irradiated yeast cells served as control.
Results: After 24, 48 and 72 hours of irradiation growth rate was reduced, the maximum reduction occurring after 20 minute. There was no difference between irradiated and non-irradiated C. albicans samples as regards sugars assimilation. Irradiation could inhibit production of chlamidoconidia by the fungus, the magnitude of inhibition increasing with increasing length of exposure to irradiation, such that after 20 minutes no chlamidoconidia could be seen in the medium. Further analysis of the data showed that pathogenicities of the fungus in irradiated and control samples were not statistically different. Neither was there any difference between them as regards size or number of bands of DNA molecules on 1% agarose gel.
Conclusion: The findings throw some light on how UVB irradiation can affect the phenotype of C. albicans isolates. Certainly more studies, e.g., on gene regulation, are required to find the effects of UVB at the molecular level in this fungus.

Abstract
Background and Aim: Xylanases are widely used in various food industries, including livestock and poultry feed industries, the pulp and paper industry, as well as the pharmaceutical industry. Several strains of microorganisms are capable of producing this enzyme by different mechanisms, Bacilliaceae being one of its important sources at the commercial scale. The culture medium for xylan is expensive and, therefore, it is not economical to use in producing xylanase by Bacillus subtilis S7e. The purpose of this study was to explore the possibility of using industrial-agricultural wastes as a source of carbon and nitrogen in submerged fermentation, for producing xylanase in amounts higher than that which can be produced by xylan culture (10048 U/).
Materials and methods: The indigenous strain of Bacillus subtilis S7e was cultured in the xylan medium, followed by incubation at 30°, 37° and 40° C. Then the nitrogen sources (rapeseed meal, soybean meal, tomato seeds, tea seeds, peptone, Vinas alcohol, casein, and ammonium sulfate) and carbon sources (molasses, wheat bran, rice bran, rice industry waste, gluten waste, malt waste, whey powder, and bagasse) were substituted for the meat and yeast extracts and the xylan culture medium, respectively.
Results : The maximum enzyme activity was observed at 30° C after 48 hours of incubation (6183U/l). Rapeseed meal with an enzyme activity of 10048U/l and molasses with an enzyme activity of 3759U/l were found to be the best nitrogen and carbon sources for Bacillus subtilis S7e , respectively.
Conclusion: Based on the findings of this study, f rom an economic point of view, agricultural-industrial wastes (rapeseed meal and molasses) are an excellent substitute for the more expensive culture media currently in use for producing the enzyme xylanase.

Abstract
Background and Aim: The hypersexual disorder is described as multiple unsuccessful attempts to control or diminish the amount of time spent on engaging in sexual fantasies, urges, and behaviors in response to dysphoric mood states or stressful life events. The purpose of the present research was to determine the validity, reliability and factor structure of the Hypersexual Behavior Inventory (HBI) for use for students, developed by Reid and colleagues.
Materials and Methods: In this descriptive study, 300 male students of Azarbaijan Shahid Madani University were selected by cluster random sampling on the basis of school and field of study. Data were collected using the HBI, and its reliability and validity were determined using Cronbach’s alpha and confirmatory factor analysis (CFA).
Results: The reliability coefficients obtained for control, consequences, coping components and total scale were 0.82, 0.80, 0.86 and 0.90, respectively, which showed good reliability. In addition, the results of factor analysis showed a statistically significant association between observed variables (questions) and the latent structures (factors), indicating an appropriate/desirable fitness for the three-factor structure in the sample (GFI = 0.91, AGFI= 0.88, CFI= 098, RMSEA= 0.057).
Conclusion: The Hypersexual Behavior Inventory is a valid and reliable tool to be used for the students, and, therefore, the use of this tool in future research is recommended.

Abstract
Background and Aim: Nowadays, the need for informing children and teens in different ages, about sexual problems, is felt more than ever before. Sexual training and education; such as every other original training, must be done at the right place and time. On the other hand, this training should be based on a systematic program and educational models to achieve the desire results. The aim of this study is to determine the effect of educational intervention on the BAZNEF Model on mother's skill about sexual care of their children, Tehran 2017.
Materials and Methods: This study was a quasi-experimental intervention with control group. Ninety six mothers of children aged 5-6 were selected in Tehran pre-schools. They were randomly divided into two groups; intervention and control. Data were collected by a researcher made questionnaire based on BAZNEF Model whose the validity and reliability were confirmed. After pre-test, according to educational needs, educational content and program were based on BAZNEF Model and that were conducted in the intervention group. Data were analyzed by SPSS23, independent t, Mann-Whitney and Chi- squar statistic tests.
Results: The mean scores of attitude, subjective norms, behavioral intention and behavior showed no significant difference before the education in both intervention and control group. However, the result showed compelling difference in mean scores of attitude, subjective norms, behavioral intention and behavior after the education (p<0/001).Enabling factors showed no important variation among intervention and control groups before and after the experiment.
Conclusion: The finding of current study confirmed the educational intervention, based on BAZNEF Model, was effective on mother's attitude, subjective norms, behavioral intention and behavior about sexual care of their children.

Abstract
Background and Aim: One of the complex processes in the Ministry of Health and Medical Education in Iran is the process of registering pharmaceutical supplies. Currently the registration process is a multi-stage process, resulting in parallel services, a waste of time and unnecessary expenses. Therefore, an integrated system will improve the relevant service delivery. The purpose of this study was to identify a set of activities that could be collectively considered as a single service to create an integrated system for registering pharmaceutical supplies in the Ministry of Health and Medical Education, Iran.
Materials and Methods: This was an applied research, beginning with collecting information about the registration processes for 20 different products. In order to identify the services/steps of an integrated system for recording pharmaceutical supplies, first the Gray-Wolf multi-objective optimization (GWO) algorithm was proposed. Then the values of the algorithm parameters were extracted by the goal-based requirements analysis method and the algorithm was implemented. Finally the best services were extracted by the hierarchical analysis process.
Results: Through the proposed algorithm seven services were identified, including product class inquiry, document registration, document review according to license type and product class, licensing, laboratory services, clinical studies and payment service. These services were carefully approved with a precision of 97.3 by the experts of the Ministry of Health. The proposed framework for recording drug requirements was found to be effective and could facilitate the process by up to 90%, reduce the processing time by 80% and reduce the processing costs by 65%.
Conclusion: Creating an integrated system for registering pharmaceutical supplies is one of the important challenges of the Ministry of Health and Medical Education. This can be achieved by identifying services and combining these services to create an integrated system.
