Locating Post Offices Using Fuzzy Goal Programming and Geographical Information System (GIS)

This paper deals with the problem of locating new post offices in a megacity. To do so, a combination of geographicalinformation system (GIS) and fuzzy goal programming (FGP) is used. In order to locate new offices, first six types of servicefacilities with high levels of interactions with post offices are defined. Then, aspiration level of proximity for each servicefacility is determined. Based on these values, a fuzzy goal programming model is constructed to find potential locations offacilities. In order to determine the optimal locations among potential facilities, a maximal covering location problem(MCLP) is solved and results are reported. Results show that although the current state is near-optimal, for future expansionsof the network, the government should spend money on central and southern parts of this megacity

Sleep Quality in Women with Endometriosis

Background: Endometriosis is a gynecological disorder characterized as the implantation of endometrial tissue outside the uterine cavity. Psychological symptoms such as anxiety, bipolar disorder, depressive symptom and impaired quality of life are common in these women. Sleep quality had not been considered in these women as it should be. The goal of this study was to evaluate sleep quality in women with endometriosis.Methods: In this cross-sectional study 61 married women with laparoscopically diagnosed endometriosis asked to fill valid and reliable Pittsburgh Sleep Quality Index (PSQI).Results: Mean age and mean education level were 31.4±6.7 years and 11.7±3.1 years, respectively. Dysmenorrhea followed by dyspareunia was the most common symptoms (68.8% and 40.3%). Mean PSQI score was 6.1±3.4, twenty eight (45.9%) had PSQI score equal or less than 5 and 33 (54.1%) had PSQI score more than 5 (poor sleep). Mean PSQI was significantly different between cases with and without dysmenorrhea and dyspareunia.Conclusion: Sleep quality should be considered in women with endometriosis

Evaluation of Yazd Dentist’s Knowledge, Attitude and Performance of Aesthetic Management of Anterior Composite Restorations in 2020

Introduction: Nowadays, due to the rapid development of new resin restorative materials and extensive media advertising concerning the importance and impact of a beautiful smile, there is an increased demand for the restoration of anterior teeth; thus, the beauty of smile is rendered as a major concern for patients and dentists. Methods: In this cross-sectional descriptive study, 165 general dentists in Yazd City, Iran were selected by random sampling. Of these, 158 dentists completed the study questionnaire, including 5 demographic items and 38 more items in three parts: knowledge, attitude and performance. Gleaned data were analyzed with SPSS 16 using T-test, one-way ANOVA, descriptive statistics (frequency/percentage). Results: In this study, 39.9% of dentists were male and 60.1% were female. There was no statistically significant correlation between the scores of attitude and knowledge with gender, age, history of activity, and the university of dentists' study (P>0.05). Yet, a statistically significant correlation was observed between the average attitude scores of dentists who participated in training courses and the dentists who did not participate in training courses (P<0.05). Conclusion: Based on the results of the present study, dentists had average knowledge and poor attitude regarding the aesthetic management of anterior composite restorations. However, participation in courses and workshops on aesthetic management of anterior composite restorations had a great impact on dentists' attitudes. Moreover, most dentists were not satisfied with the Dental School's training regarding anterior composite restorations
