Factors Affecting Minor Psychiatric Disorder in Southern Iranian Nurses: A Latent Class Regression Analysis

Background: Mental health is one of the most important dimensions of life and its quality. Minor Psychiatric Disorder as a type of mental health problem is prevalent among health workers. Nursing is considered to be one of the most stressful occupations. Objectives: This study aimed to evaluate the prevalence of minor psychiatric disorder and its associated factors among nurses in southern Iran. Patients and Methods: A cross-sectional study was carried out on 771 nurses working in 20 cities of Bushehr and Fars provinces in southern Iran. Participants were recruited through multi-stage sampling during 2014. The General Health Questionnaire (GHQ-12) was used for screening of minor psychiatric disorder in nurses. Latent Class Regression was used to analyze the data. Results: The prevalence of minor psychiatric disorder among nurses was estimated to be 27.5%. Gender and sleep disorders were significant factors in determining the level of minor psychiatric disorder (P Values of 0.04 and < 0.001, respectively). Female nurses were 20% more likely than males to be classified into the minor psychiatric disorder group. Conclusions: The results of this study provide information about the prevalence of minor psychiatric disorder among nurses, and factors, which affect the prevalence of such disorders. These findings can be used in strategic planning processes to improve nurses’ mental health

Determinants of patient satisfaction with ultrasound-assisted liposuction

Background: Liposuction is one of the most common aesthetic procedures and a number of options are available to practitioners in terms of surgical technique. One of those options is ultrasound-assisted liposuction (UAL), which has garnered considerable attention in the literature and from patients themselves. Because the role of ultrasound in body sculpting is continuing to increase over time, the authors believe that a comprehensive assessment of patient satisfaction after the procedure is essential. Currently, there are very few reports in the literature examining patient satisfaction with UAL, and to the authors' knowledge, no reports in the literature have successfully outlined the determinants and predictors of long-term satisfaction with the procedure. Objective: The authors examine the correlates and predictors of patient satisfaction after UAL. Methods: The authors conducted a prospective cross-sectional study on 609 consecutive patients who underwent UAL from 2002 to 2008. One hundred and sixty (54) out of 300 patients with whom the authors could make contact agreed to answer a standardized questionnaire regarding their overall satisfaction. Results: Nearly 80 of the patients were completely or mostly satisfied with UAL. Seventy-five percent reported that they had or would recommend UAL to others. Women (P =.009), patients who did not gain weight after their UAL procedure (P <.001), patients who were content with their body appearance (P <.001), patients whose dress sizes decreased after UAL (P =.001), and patients with confidence in their body (P <.001) showed statistically significant higher rates of satisfaction with UAL. Among these correlates, confidence in body (odds ratio OR = 24.4; 95% confidence interval CI: 6.8-83.3) and contentment with body appearance (OR = 5.5; 95% CI: 1.5-19.4) were found to be reliable independent predictors of patient satisfaction. Conclusion: Most patients were satisfied with UAL, but certain patient responses were more highly correlated with overall satisfaction than others and therefore can be considered predictors of long-term patient satisfaction with this procedure. The results of this study may provide plastic surgeons with valuable clues that can enhance preoperative planning and therefore enable further improvement of patients' satisfaction with UAL. © 2010 The American Society for Aesthetic Plastic Surgery, Inc

Nanotechnology and global energy demand: challenges and prospects for a paradigm shift in the oil and gas industry.

The exploitation of new hydrocarbon discoveries in meeting the present global energy demand is a function of the availability and application of new technologies. The relevance of new technologies is borne out of the complex subsurface architecture and conditions of offshore petroleum plays. Conventional techniques, from drilling to production, for exploiting these discoveries may require adaption for such subsurface conditions as they fail under conditions of high pressure and high temperature. The oil and gas industry over the past decades has witnessed increased research into the use of nanotechnology with great promise for drilling operations, enhanced oil recovery, reservoir characterization, production, etc. The prospect for a paradigm shift towards the application of nanotechnology in the oil and gas industry is constrained by evolving challenges with its progression. This paper gave a review of developments from nano-research in the oil and gas industry, challenges and recommendations

Background & aim: Due to the high prevalence of chronic non-specific back pain and its effects on daily activities and people's lifestyle, it is important to study about new treatment perspectives and therapeutic exercises for this disease. Therefore, the aim of the present study was to determine and evaluate the effect of eight weeks of exercises. It was based on prayer movements on the amount of pain and endurance of trunk flexor and extensor muscles in patients with non-specific chronic back pain. Methods: The present semi-experimental study was conducted in 2019. the research population included all patients with non-specific chronic back pain referred to Shahid Muftah Clinic No. 1 in Yasuj, Iran. Sixty-six eligible patients were selected by non-probability sampling method and were divided into two groups based on random block allocation: test (33 people) and control (33 people). Two participants from the intervention group refused to participate in the study during the implementation of the intervention. For the patients of the test group, exercises based on prayer movements were performed 3 times a week for 8 weeks, and no training was given to the control group. From the demographic data collection form and the Quebec back pain disability questionnaire, the visual pain measurement scale, the 60-degree body support test and the Byring Sorensen test to collect data before the intervention and immediately after the intervention from the visual measurement scale Pain, one week after the intervention, the body maintenance test at a 60-degree angle and Sorensen bearings were used. The collected data were analyzed using t-paired, Man-Whitney, independent t, Wilcoxon, chi-score and Shapiro-Wilk statistical tests. Results: At the starting point of the study, there was no significant difference between the groups under study in terms of the amount of pain and endurance of the trunk muscles, except for the endurance of the extensor muscles (p<0.05). After the completion of the research intervention, a significant decrease in the amount of pain and a significant increase in the endurance of the trunk muscles were observed (p<0.05). Conclusion: According to the results of the present study, increasing the level of endurance of flexor muscles, trunk extensors and relieving pain and improving the level of performance in patients with non-specific chronic back pain, it can be said that exercises based on prayer movements had an effect on the level of pain and endurance of trunk muscles in patients. Suffering from non-specific chronic back pain, it was effective

Background & aim:  Evaluation is an integral part of educational programs and undoubtedly, for conducting appropriate evaluation Students should be evaluated in simulated conditions of the future workplace. The purpose of the present study was to design, implement and evaluate an objective structured practical test to assess the practical capabilities of environmental health engineering students at Yasuj Health Faculty in 2020-2021. Methods: In the present descriptive study, 18 senior students of Environmental Health Engineering of Yasuj School of Health and Nutrition Sciences in 2021 were studied. The study instruments were checklists from eleven different stations, which were prepared based on the training program of the relevant course and Its content validity was examined by a panel of experts. Students' skills were evaluated in each station by the evaluator using a checklist. At the end, students completed the Survey form. After collecting the data, it was entered into SPSS20 software and t-test, Mann-Whitney and correlation tests were used to analyze the data. Results: The results indicated that the average score of stations was more than 50% (63.54). Students in nine stations had a score above 50%, which indicated that the selected stations could be a suitable criterion for evaluating practical skills and OSFE exam was a suitable alternative to written and oral tests at the end of the semester. The score of two stations was less than 50%. This was due to the virtual nature of universities during the COVID-19 epidemic and it was not possible for the students to perform the necessary skills sufficiently during the study period. Stations with an average score of more than 70% indicate the mastery of students in the skills they have learned in laboratories and health-treatment centers. The level of students' satisfaction with the test was also 77.94%. Conclusion: According to the level of student satisfaction (77.94), it can be said that this exam is a suitable and student-friendly method for assessment and its use is suitable for different courses. Given the average scores that are above average, it seems necessary to review the evaluation methods in the practical sections

Badanie wpływu właściwości skał na prędkość wiercenia przy zastosowaniu metod statystycznych i inteligentnych: studium przypadku: szyb naftowy w południowo-zachodniej części Iranu

Rate of penetration (ROP) is one of the key indicators of drilling operation performance. The estimation of ROP in drilling engineering is very important in terms of more accurate assessment of drilling time which affects operation costs. Hence, estimation of a ROP model using operational and environmental parameters is crucial. For this purpose, firstly physical and mechanical properties of rock were derived from well logs. Correlation between the pair data were determined to find influential parameters on ROP. A new ROP model has been developed in one of the Azadegan oil field wells in southwest of Iran. The model has been simulated using Multiple Nonlinear Regression (MNR) and Artificial Neural Network (ANN). By adding the rock properties, the estimation of the models were precisely improved. The results of simulation using MNR and ANN methods showed correlation coefficients of 0.62 and 0.87, respectively. It was concluded that the performance of ANN model in ROP prediction is fairly better than MNR method.Prędkość wiercenia jest jednym z podstawowych parametrów charakteryzujących tempo prac wiertniczych. Oszacowanie prędkości wiercenia jest zagadnieniem kluczowym dla inżynierów wiertnictwa, gdyż pozwala na dokładne określenie czasu trwania prac, a co za tym idzie także kosztów operacyjnych. Szacowanie prędkości wiercenia odbywa się na podstawie modelu uwzględniającego parametry pracy oraz parametry środowiskowe. Pierwszy krok obejmuje pozyskanie danych o fizycznych i mechanicznych właściwościach skał na podstawie profilowania geofizycznego otworu. Zastosowano korelację odpowiednich par danych dla pokreślenie wpływu głównych czynników warunkujących prędkość wiercenia. Nowy model obliczania prędkości wiercenia opracowany został w okręgu naftowym Azadegan w południowo-zachodniej części Iranu. Symulacje prowadzono w oparciu o metodę wielokrotnej regresji nieliniowej a także przy wykorzystaniu sztucznych sieci neuronowych. Poprzez dodanie danych o właściwościach skał, model został znacznie udoskonalony. Wyniki symulacji prowadzonych w oparciu o powyższe metody wykazały współczynniki korelacji na poziomie 0.62 i 0.87. Stwierdzono, że metoda wykorzystująca sztuczne sieci neuronowe daje dokładniejsze szacunki prędkości wiercenia niż podejście bazujące wyłącznie na metodzie obliczania regresji nieliniowe
