مقدمه: پیشرفت تکنولوژی انعطاف پذیری شغلی را برای کارمندان و کارفرمایان به طور یکسان افزایش داده است. با توجه به اینکه دورکاری موثر نیاز به برنامه ریزی دارد، همه گیری COVID-19 بسیاری از کارمندان را به سرعت به تغییر محل کار از بیرون به خانه، بدون اطمینان داشتن از مهیا بودن شرایط وا داشت. هدف از انجام این مطالعه بررسی تاثیر دورکاری بر اختلالات اسکلتی عضلانی و عوامل روانی-اجتماعی در ایام کرونا است. روش کار: این پژوهش به روش مروری انجام شده است. جستجوی مقالات از سال 2020 تا 2023 در سایت های PubMed، Science Direct، Google Scholar و با کلمات اصلی  Ergonomics، Teleworking، MSDs، ، COVID19صورت گرفت. یافته ها: در مجموع 93 مقاله در جستجوی اولیه انتخاب شدند. با ارزیابی عنوان ها، 45 مقاله مرتبط و با بررسی چکیده ها 30 مقاله که  در نهایت 13 مقاله که فول تکست آن ها در دسترس بود انتخاب شدند. این مقالات به بررسی تاثیرات دورکاری بر اختلالات  اسکلتی عضلانی و عوامل اجتماعی روانی در دوران کرونا اشاره دارند. نتیجه گیری: بیشتر مطالعات بر افزایش ناراحتی های اسکلتی عضلانی اشاره دارند. دورکارها درد و ناراحتی اسکلتی عضلانی را بیشتر در نواحی مختلف بدن تجربه کرده اند. ساعات کاری طولانی تر با استراحت کوتاه تر برای برآورده کردن افزایش تقاضای کاری، انزوای اجتماعی، عدم حمایت همکاران، مرزهای مبهم کار و خانه و حضور همه جانبه شغلی، از عوامل روانی اجتماعی و سازمانی مرتبط با اختلالات اسکلتی عضلانی هستند. برای تعدادی از کارمندان، دورکاری به عنوان یک روش معمول کار در دوره پس از همه گیری باقی خواهد ماند. بنابراین، شناسایی عوامل خطر مرتبط با دورکاری برای اختلالات اسکلتی عضلانی و رسیدگی به آنها با اقدامات پیشگیرانه به موقع از راه دور و نیازهای فردی کارمندان ضروری است.

The Big Five Inventory (BFI) is one of the most widely used personality questionnaires, but very few studies have been conducted on its psychometric properties in Iranian population. This study was carried out with the aim of studying the psychometric properties of the BFI questionnaire. For this purpose, 390 university students in Tehran (210 girls and 180 boys) with an age range of 18 to 56 years (M = 27.52; SD = 8.79) were selected using the convenience sampling method and completed BFI and NEO-FFI questionnaires. Cronbach's alpha, multitrait-multimethod matrix, and confirmatory factor analysis were used to estimate the psychometric properties of the questionnaire. The result of the confirmatory factor analysis showed that 15 of the 44 items did not have a strong factor loading (higher than 0.40) on the corresponding factors and were therefore removed from the questionnaire. The fit indices showed that the Persian version of 29 questions (BFI-29) with 5 factors has a good fit with the data. The reliability analysis also showed that the range of Cronbach's alpha coefficients of the factors is from 0.70 to 0.79. The lowest Cronbach's alpha coefficient was related to agreeableness factor and the highest was related to conscientiousness. The findings from the multitrait-multimethod matrix showed that the BFI-29 questionnaire has good convergent and divergent validity with the NEO-FFI questionnaire. In general, based on the results of the present study, it can be said that the BFI-29 questionnaire has desirable psychometric properties and whenever a short tool for personality measurement is needed, this questionnaire can be used.

Abstract: This study sought to answer the question of what are the causes of marital infidelity in the Iranian family. To Answer the Research Question, Qualitative Meta-Synthesis (QMS) Method Were Used. Then, 78 Scientific Papers Which Were Considered Marital Infidelity in Iran were identified and were Analyzed. The results showed that the factors of infidelity in Iran can be classified into 9 main categories, including: 1. Social factors, 2. Psychological factors, 3. Cultural factors, 4. Family factors, 5. Personal factors, 6. Relational factors, 7. Economic factors, 8. Media factors, 9. Contextual factors. Each of the main Categories is divided into Different Subcategories. The Social Factors of infidelity were including “Infidelity Opportunities”, “Friend groups” and “Environmental Conditions”. Psychological Factors of Infidelity Were Including “Personality Type”, “Attachment Styles”, and their “Love Schema”. Cultural Factors have Pointed to “Change in Beliefs and values” and “the level of Religious Education” of people. The Family Factors were including “Inappropriate Marriage”, “Family Conflict” and “the Kind of Family Background of people”. The Personal Factors are “Sexual Dissatisfaction”, “Emotional Dissatisfaction”, “the Feeling of Loneliness”, “the Spouse Unavailability”, “Weakness in Controlling Spouse”, “Domestic Violence”, “Revenge of the Spouse” and “the Role of the Third Person in the Relationship”. The Economic factors are including “the Economic Status of the person”, “the Role of Economic Problems”, “the motivation of entering into infidelity under the Pretext of Job promotion”. The media Factors Were Emphasized on “weakening Iranian Values through Social Media Networks and Foreign Satellite Channels” and “Producing of New Needs by Media”. Finally, the Contextual Factors were including the Role of “Age” and “Gender” in the Infidelity. Findings showed that Infidelity Occurred in the group of men and youth in Iran, more than other Social Groups.

زمینه و هدف: در مورد علت درگیری بعضی نواحی خاص لثه (نواحی دندان های 1 بالا و6 بالا و پایین) در برخی بیماری های پریودنتال، هیچ توجیه قابل توجهی عنوان نشده است. با توجه به این که مناطق یاد شده نزدیک فورامن های محل گذر اعصاب قرار دارند و با توجه به این که نوروپپتیدها که از انتهای اعصاب آزاد می شوند، نقش مهمی در برانگیختن التهاب دارند، همچنین از آنجایی که به نقش  SP و CGRP در بیماری های پریودنتال اشاره شده، بنابراین این تحقیق با هدف تعیین رابطه میان غلظت نوروپپتیدها با بافت سالم لثه نواحی مختلف دندانی صورت پذیرفت. مواد وروش ها: برای انجام این مطالعه تحلیلی، 17 نمونه بافت سالم لثه مربوط به دندان های 1 بالا و6 بالا و پایین (گروه مورد) و 23 نمونه بافت سالم لثه مربوط به سایر نواحی دندانی (گروه شاهد) جمع آوری شدند. نمونه های جمع آوری شده مورد کشت 72 ساعته بافتی قرار گرفته، با روش EIA به تعیین غلظت SP و CGRP در مایع رویی (supernatant) کشت آن ها اقدام شد. جهت انجام آنالیزهای آماری از آزمون های آماری غیرپارامتری (Non Parametric) U Mann Whitney و تعیین ضریب همبستگی Spearman استفاده گردید. یافته ها: در تمامی نمونه های مورد مطالعه، به حضور قابل توجه هر دو نوروپپتید برخورد شد. در مورد CGRP مشخص شد که غلظت این نوروپپتید در لثه مربوط به نواحی دندانی 6 بالا و پایین، به طور قابل توجهی پایین تر از سایر نواحی بود (P ≈ 0.023). در مورد SP به اختلاف آماری معنی دار بین گروه های مورد و شاهد برخورد نشد. نتیجه گیری: براساس یافته های به دست آمده از این تحقیق و با توجه به حضور SP و CGRP در تمام نمونه های بافت سالم لثه می توان چنین نتیجه گیری کرد که این دو نوروپپتید، احتمالا در تنظیم حفظ سلامت بافت لثه نقش دارند و با توجه به پایین تر بودن غلظت CGRP در نواحی دندانی 6 بالا و پایین، شاید بتوان یکی از دلایل درگیری بیشتر این نواحی در برخی بیماری ها به پایین بودن غلظت این نوروپپتید نسبت داد.

Identifying the constraining factors of production and yield gap is very important. Therefore; this research was performed to identify the production constraining factors of local rice cultivars. All management practices from nursery preparation to harvesting stages for 100 paddy fields of local rice cultivars were recorded through field studies, in Sari, from 2015-2016. In the CPA, the actual and calculated potential yield were 4495 and 5703 kg/ha, respectively and the gap was 1221 kg/ha. The yield gap caused by number of top-dressing variables was 324 kg/ha, equal to 27% of the total yield gap. The yield gap related to previous year of legumes cultivation was 218 kg ha-1, equal to 18% of the total yield variation. Among the 10 variables entered in the CPA model, the effects of top-dress fertilizer application and its application frequency and foliar application were remarkable, which could compensate a significant part of the yield gap (444 kg/ha, 37% of total) in the farmers’ fields by managing these variables. According to boundary line analysis (BLA) finding, actual yield mean on the basis of optimal limit related to 12 variables under study was 5369 kg/ha, with 881 kg/ha yield gap . Mean relative yield and relative yield gap for 12 variables (transplanting date, seedling age, number of seedlings per hill, planting density, nitrogen and phosphorous per hectare, nitrogen before transplanting, harvesting date, lodging problem, pest problem, diseases problem and weeds problem) were 83.64 and 16.35 kg/ha, respectively. Based on the finding, it can be stated that the model precision is appropriate and can be applied for both estimation of the quantity of yield gap and determining the portion of each restricting yield variables.

هدف: مطالعات از افزایش روند سالمندی و ناتوانی های آن در کشورهای در حال توسعه و روند نزولی ناتوانی ها در کشورهای غربی گزارش می دهند. با وجود این سلامت و وضعیت ناتوانی سالمندان در کشور ما مورد کم توجهی قرار گرفته است. این پژوهش با هدف بررسی میزان ناتوانی و برخی عوامل مرتبط با آن در سالمندان کاشان انجام شد.روش بررسی: پژوهش به صورت تحلیلی مقطعی بر یک نمونه 350 نفری از سالمندان 65 سال و بالاتر شهر کاشان انجام شد. از پرسشنامه سازمان بهداشت جهانی برای بررسی ناتوانی سالمندان (WHO-DAS-II) استفاده شد. این پرسشنامه دارای 48 سوال است که هر فرد می تواند نمره ای بین 0 تا 144 از آن کسب کند. برای بررسی ارتباط ناتوانی با خصوصیات سالمندان از آمار تحلیلی t و تحلیل واریانس استفاده شد.یافته ها: 61%  واحدهای پژوهش را مردان تشکیل دادند. 12% از سالمندان به تنهایی زندگی می کردند. یک چهارم سالمندان سیگار یا مواد اعتیاد آور مصرف می کردند. اکثر آنها بیسواد یا دارای سواد ابتدایی بودند. بیش از دو سوم فاقد فعالیت منظم فیزیکی بودند. 20% سالمندان ناتوانی متوسط و %4.3 ناتوانی شدید داشتند. ارتباط معنی داری میان شدت ناتوانی با سن، جنس، شیوه زندگی، نیاز به کمک، وضعیت تاهل، محل سکونت، اعتیاد ، توانایی کار کردن، فعالیت منظم بدنی، سطح سواد و نیز ابتلا به چند بیماری مشاهده شد.نتیجه گیری: سالمندان مطالعه حاضر در مقایسه با سایر کشورها از ناتوانی کمتری برخوردار بودند اما با توجه به روند افزایش جمعیت سالمندان، توجه به سلامت کاهش ناتوانیهای آنها ضروری است. بیشتر بودن شدت ناتوانی در زنان و افراد کم سواد ضرورت توجه به این گروههای آسیب پذیر را نشان می دهد.

ABSTRACT Despite a wide range of components and criteria affecting travel behavior presented through empirical research, the results of these studies are inconclusive, which could be due to the difference between these components and criteria in the study areas. Therefore, this research presented a method to determine which factors in different physical developments affect travel behavior due to the differences in various physical developments. The required information was collected through 271 questionnaires at the level of three neighborhoods of Monirieh, Koye Bimeh, and Koye Golestan in Tehran, Iran, as the old, conventional, and new neighborhoods, respectively. ANOVA test was exerted to analyze the significant difference between different development patterns in three neighborhoods. Dunnett's T3 was applied to determine which neighborhood caused the difference between groups. Also, the factors affecting travel behavior were obtained based on exploratory factor analysis indicators. Finally, by comparing the results of the ANOVA test and regression analysis, it was discovered that factors such as car ownership, dependence and pro-liking for private cars, density and access to educational centers and parks, access to medical and service centers, and variety and density of retail stores had been introduced as the factors affecting travel behavior due to the differences in development patterns. However, proximity to the public transportation station, accessibility preferences in choosing a residence, dependence, and pro-liking for other than a private car, having a license, number of children under five years old, and age have influenced travel behavior regardless of the variation between neighborhoods. Extended Abstract Introduction Finding factors affecting travel behavior has been one of the main concerns of transportation planners. However, in the last two decades, the importance of the influence of the features of the built environment, including land use, along with demographic-economic characteristics, travel behavior, and attitudes of people, has been raised by urban planners. Studies seek to find factors affecting travel behavior, especially land use characteristics. Despite presenting a wide range of components and criteria affecting travel behavior, the results of the studies are inconclusive, which could be due to the difference between these components and criteria in the study areas. Therefore, this research presented a method to determine which factors in different physical developments affect travel behavior due to the differences in various physical developments. In order to do this, it must first be determined whether the study areas/different development patterns have a significant difference in terms of travel behavior or not. In case of a positive answer to the previous question, the following question is which study areas caused this difference. The next question arises: -Which physical and non-physical characteristics affect travel behavior due to distinctions between different development patterns?   Methodology The present research method is analytical and experimental based on quantitative methods. This research chose the frequency of travel by private car, public transportation, and walking as the travel behavior. According to the research's purpose, indicators and criteria affecting travel behavior were extracted after reviewing the theoretical and experimental literature. Then, the required information was collected through 271 questionnaires at the level of three neighborhoods of Monirieh, Koye Bimeh, and Koye Golestan as the old, conventional, and new neighborhoods, respectively. The questionnaire was compiled as a Likert scale in five parts of travel information, demographic-economic characteristics, perceptual characteristics of land use, travel habits, and access preferences of people in choosing their residence. ANOVA test was used to analyze the significant difference between different groups of a characteristic (here, different development patterns or the three case studies). Dunnett T3 was exerted to determine which neighborhood caused the difference between groups. Also, the factors affecting travel behavior were obtained based on exploratory factor analysis indicators. Finally, by comparing the results of the ANOVA test and regression analysis, it was discovered which factors affecting travel behavior were due to the differences in study areas and which factors affect travel behavior regardless of development patterns.   Results and discussion This research aims to identify the factors affecting travel behavior due to the differences in development patterns. In this regard, the findings in line with the first research question show that the frequency of three modes of travel, by private car, transportation, and pedestrian, differ significantly in the three neighborhoods. Furthermore, ANOVA test results depict that there is a significant difference between these three neighborhoods in terms of factors affecting travel behavior, such as perceptually environmental characteristics of the neighborhood, dependence and pro-liking for personal cars, variety and density of retail stores, density and access to educational units and parks, access to medical and service centers, and car ownership. Finally, by comparing the results of the ANOVA test with the regression analysis assessing the relationship between physical and non-physical factors (the same indicators in the same study areas) with travel behavior, the factors affecting travel behavior owing to different development patterns were identified. Factors such as car ownership, dependence and pro-liking for private cars, density and access to educational units and parks, access to medical and service centers, and variety and density of retail stores have been introduced as the factors affecting travel behavior due to the differences in development patterns. However, proximity to the public transportation station, accessibility preferences in choosing a place of residence, dependence, and pro-liking for other than a private car, having a certificate, number of children under five years old, and age have influenced on travel behavior regardless of the variation between neighborhoods (different physical development patterns).   Conclusion In In order to discover the factors affecting travel behavior due to the differences in patterns of physical development, this research has provided a more detailed analysis of the factors affecting travel behavior. It has achieved more accurate components than previous studies in this regard. Detailed analysis of studies related to travel behavior and finding the main components affecting it, considering the extent of variables and data, can pave the way for professionals in transportation planning and urban planning, in addition to providing detailed methods and criteria in the related literature.   Funding There is no funding support.   Authors’ Contribution Authors contributed equally to the conceptualization and writing of the article.
