Abstract
Introduction and purpose: Parasitic diseases have led to economic and health problems around the world. One of the most common ways for the transmission of these diseases is the consumption of raw vegetables contaminated with parasite. These diseases can be prevented through obtaining knowledge about the parasitic contamination of the vegetables. Regarding this, the aim of the present study was to evaluate the prevalence and type of raw vegetables contamination in Sanandaj, Iran, in 2013.Methods: This cross-sectional study was conducted on 360 vegetable samples distributed in 60 greengroceries in Sanandaj in 2017. The data were analyzed using the SPSS version 16.Results: In total, 16.3% of the vegetable samples were contaminated with various types of parasites, including free-living nematode (12.2%), Entamoeba coli (1.7%), Giardia (0.8%), Blastocystis hominis (0.8%), and Dicrocoelium (0.8%). However, most of the contaminations (81.6%) were found in the vegetables, which were imported from regions other than Kurdistan province. Basil had the highest level of contamination, whereas coriander and lettuce had the lowest contamination level (P=0<05). Additionally, the vegetables had the highest and lowest contamination levels in the winter and spring, respectively.Conclusion: Regarding the findings of the present study, it is recommend to thoroughly perform parasite decontamination before the consumption of vegetables. Furthermore, the officials can prevent the parasitic diseases by careful monitoring of public food distribution centers and controlling the source of vegetables in the winter.

Abstract
Introduction and purpose: Ticks as biological vectors and reservoirs of diseases, such as Crimean-Congo hemorrhagic fever (CCHF), have an important role in the transmission of pathogens to humans and animals. In this regard, this study aimed to determine the biodiversity indices, distribution, and fauna of the vectors of CCHF in Ahvaz, Iran.
Methods: The tick samples were collected and identified from the head, ear, groin, under the tail, and around the rectum of cattle, sheep, and goats in spring and autumn. Biodiversity indices were calculated based on the host type. Moreover, the frequency map of the ticks was drawn using ArcGIS software (version 10.4).
Results: A total of 287 livestock were examined in this descriptive cross-sectional study. Overall, five species of tick were identified from three genera. Frequency rates of Hyalomma marginatum, Hyalomma anatolicum, Rhipicephalus bursa, Rhipicephalus sanguineus, and Boophilus annulatus were calculated as 21.25%, 2.5%, 61.25%, 11.25%, and 3.75%, respectively. According to the Shannon-Weiner index, the species diversity of the goat host was less than that of the hosts of cow and sheep. In addition, based on the Simpson index, the diversity of dominant species in the goat host was less than that of the other two hosts. Furthermore, the species richness index in sheep host was the highest among the hosts. However, the evenness index of the species based on the host type was calculated to be the highest equal to 0.789 for the host of the cow.
Conclusion: According to the obtained results, there was a relation between biodiversity indices and tick-borne diseases. The aforementioned relationship provides useful information in terms of preventing diseases transmitted by ticks.

Abstract
Introduction and purpose: Manpower is the most important element of organizational productivity. The improvement of the level of creativity as a component affecting the performance of individuals has always been an undeniable necessity in organizational productivity. This study investigated the correlation between creativity and productivity among the staff of Hamadan University of Medical Sciences, Hamadan, Iran.
Methods: This descriptive-analytical study was conducted based on a correlational and cross-sectional research approach at Hamadan University of Medical Sciences, Hamadan, Iran, in 2022. The sample size was estimated at 327 people based on Cochran's formula. The data were collected using Employee Productivity Questionnaire (ACHIEVE Model Hersey & Goldsmith) and Rendsip's Creativity Questionnaire. The data were analyzed in SPSS software (version 22) through descriptive statistics (frequency, percentage, and mean±SD) and inferential statistics (correlation coefficient).
Results: There is a relationship between creativity and productivity of university staff. Moreover, creativity had a significant effect on productivity components. Regarding the productivity levels, ability and understanding, motivation and credibility, as well as organizational support, feedback, and adaptation, ranked the first, last, and average, respectively. The correlation coefficient of creativity and employee productivity was obtained at 0.148 (P=0.008). No significant difference was observed between the creativity and productivity scores of the staff regarding demographic characteristics.
Conclusion: By focusing on staff creativity, the university can achieve a more desirable level of productivity. The results showed that it is possible to nurture the creative thinking of employees due to the high level of ability and understanding of employees; however, motivation and creditability in the employees need to be improved by the university.
