Research findings on the relationship between vitamin D and suicide are not consistent; therefore, the objective of the present paper is to assess the relationship between vitamin D and suicide behaviors using a systematic review and meta-analysis.

A search strategy was developed using keywords including “Vitamin D”, “Vitamin D deficiency”, “suicide” "attempted suicide", "completed suicide”, “Suicide, Attempted”, “Suicidal Ideation.” We searched databases including Scopus, Medline, Web of Science, and Google Scholar by July 7, 2022. We examined the titles, abstracts, and full texts of the articles to select eligible ones. To pool the results of the selected studies, we used the random-effect method and mean difference as the effect size. The quality of the articles was evaluated by the Newcastle-Ottawa Scale (NOS). Moreover, heterogeneity and bias of reporting were evaluated by the I2 statistic and Egger's and Begg's tests, respectively.

Out of 149 studies retrieved in the databases, 11 studies were included in the final phase. Among these, the pooled findings of seven studies included in the meta-analysis phase showed that low levels of vitamin D are related to increased probability for suicide behaviors (P < 0.05). Moreover, subgroup analysis showed a significant relationship between vitamin D and suicide ideation and suicide attempt (P < 0.05). In addition, the I2 statistic indicated moderate heterogeneity (58%) and Egger's and Begg's tests did not show any evidence of publication bias (P > 0.05).

This study provides evidence in favor of the relationship between vitamin D and suicide behaviors. It suggests that insufficient levels of vitamin D play a role in suicidal behaviors. However, it should be noted that further and stronger evidence is needed to establish this role. Finally, incorporating vitamin D-rich foods into the diet or taking vitamin D supplements is recommended to reduce the risk of suicide.

The Loud Thinking Protocol is utilized as a verbal reporting method in the fields of psychology and cognitive sciences. aim The aim of this research is to examine the methodology of the Loud Thinking Protocol in the dimensions of education and research.

This study adopts a qualitative approach and is conducted through a systematic review.

Data collection tools include a systematic review of keywords such as "Loud Thinking Protocol, verbal thinking, thinking aloud, specified thinking" in databases such as Sid, Irandoc, Magiran, ISC, Emerald, Scholar Google, Science Direct, ProQuest, Web Science, Eric Web of, and Scopus, They were systematically examined in several stages.

In this study, 17 concepts regarding the applications of the Loud Thinking Protocol in the field of education were obtained. Some of these concepts include: influencing individual knowledge, expressing and generating new ideas, enriching classroom discourse, and serving as a means to guide behaviors and problem-solving processes. Additionally, 13 concepts regarding the applications of the Loud Thinking Protocol in the field of research were identified. Some of these concepts include: a useful and effective method in research for extracting sufficient and reliable data in the study of metacognition of readers and the use of cognitive strategies, achieving analysis of tangible data, ensuring intercoder reliability in data coding, and providing direct data.

The utilization of this protocol leads to the generation of new ideas and the production of valuable and direct data in research. Its application creates new mental and linguistic communications within a community. Moreover, it adds new information to individuals' cognitive processes, enhancing their creativity, facilitating better understanding of others' mental and emotional states, and enabling behavior alignment with expected individuals' perceptions.

Bibliotherapy is a low-cost and safe way to treat mental health problems. Given that the success of bibliotherapy depends on the positive attitude and familiarity of those involved in this therapy method, this study aims to investigate the familiarity, attitude, and use of bibliotherapy by psychologists working in counseling centers and the barriers and limitations in using bibliotherapy.

In this practical research, conducted using an analytic survey method in 2020, 101 psychologists working in counseling centers in Hamadan province, Iran, were selected by the census. The survey response rate was 100 %. All data for this study were collected using a researcher-made questionnaire. Its reliability (using the indicator of Cronbach's alpha) and validity (using two indicators of CVI and CVR) were confirmed. The data were analyzed using SPSS software version 25 using frequency distribution, Mann-Whitney, Chi-square, and Kruskal-Wallis tests.

The results showed that more than half of the participants (53.5%) were moderately familiar with the bibliotherapy, and their level of familiarity was less than average; more than half of the participants (55.4%) used moderate bibliotherapy to treat their patient's problems, and their use rate was low to medium levels. However, psychologists' attitudes toward bibliotherapy are positive and higher than average.

Despite bibliotherapy's effectiveness and psychologists' favorable view of it, awareness and utilization remain low, highlighting the need for strategies to enhance the adoption of this therapeutic approach.

ResearchGate is one of the most popular social networking websites for scholars. This study aims to investigate the presence of the faculty members of Hamadan University of Medical Sciences (HUMS) on ResearchGate by using an Altmetrics approach.

The study population consists of the profiles of the faculty members from HUMS, Hamedan, Iran on ResearchGate in 2021. For Altmetrics study, first their profiles were visited. Their data were then extracted which included Research items, Total Research Interest, Questions, Answers, Followers, Followings, Reads, Recommendations, RG Score, Citations, and h-index. Their total citations were then extracted from the Web of Science, Scopus, and Google Scholar databases. Finally, the collected data were analyzed in SPSS v. 25 software, using Kolmogorov–Smirnov test and Spearman correlation test.

All faculty members of HUMS had a profile in ResearchGate and 78.31% had joined ResearchGate. The statistical analysis showed a significant positive correlation between RG score and citations on ResearchGate, Web of Science, Scopus and Google Scholar.

Through active participation in ResearchGate and sharing published studies, medical scholars can make their works more visible and get more citations.

H-index is one of the main bibliometric indicators for evaluating researchers.It has been criticized due to the effect of self-citation rate on its increase.

This study aimed at analyzing the state of top 1% highly-cited Iranian scientists in medical sciences in ESI for investigating the effect of their self-citations on their h-indices.

Iranian Medical Science Scientometric Information Database, Essential Science IndicatorsTM(ESI) and Scopus indexing/abstracting database were used for data extraction. Data analysis was conducted in Excel and SPSS..

In total, 6.15% of citations were self-citations that resulted in increase in h-index by 2.49 units. After excluding self-citations, the h-indexes of 23.4% of the studied scientists did not change and the mean rate of h-index decreased by 2.49. A correlationaltest showed the strong correlation between self-citation count and h-index rate (r=.718).

Self-citation is present as a common phenomenon in all scientific communities and increases in h-index. If not used for manipulating bibliometric indicators, it can make the scientific works more visible for potential readers and consequently receiving more citations.

The purpose of this study is to investigate the effect of social capital on the emotional-cognitive readiness of faculty members for scientific collaborations with the presence of a mediation of psychological capital.

This practical research was conducted in an analytic-survey method. The statistical population consisted of all faculty members of two medical universities in Iran (709 people), and the sample size is calculated to be 250 people. The stratified and random sampling method was used. All data for this study were collected using three standard questionnaires: (a) Nahapiet and Ghoshal's social capital questionnaire, (b) emotional-cognitive readiness questionnaire, and (c) Lathan's psychological capital questionnaire. The Kolmogorov–Smirnov test was used to check the normality of data distribution. Spearman correlation and Structural equation modelling (SEM) were used to analyze and test hypotheses using PLS 3 and SPSS version 25.

The results showed that social capital and psychological capital and their dimensions affect cognitive-emotional readiness for scientific collaboration. Also, the findings indicate that the level or the degree at which social capital alone contributes to cognitive-emotional readiness is weaker than when it is mediated by psychological capital.

Through the creation and development of social and psychological capital, university administrators can gradually create a common language and, as a result, common insight among faculty members to provide the basis for more scientific collaboration.

This research aims to examine the influence of social capital on the emotional-cognitive readiness of faculty members for scientific collaborations using Structural Equation Modeling, considering the importance of social capital and its dimensions in social interactions. This study is applied research that was conducted in a survey method. The statistical population includes all faculty members (709) of two universities of medical sciences in Iran: Hamadan and Kurdistan universities of medical sciences. The sample size of this study was 250 people who were selected using stratified random sampling. Data were collected using two standard questionnaires. Spearman correlation and Structural equation modeling (SEM) were used to test the research hypotheses using SPSS version 25 and PLS 3. The results showed a positive and significant relationship between the dimensions of psychological capital (self-efficacy, optimism, resilience, and hope) and cognitive-emotional readiness for scientific collaboration. Also, the results obtained from Structural Equation Modeling indicated the relative compatibility of the experimental model with the conceptual model of the research, which indicates the effect of psychological capital on cognitive-emotional readiness for scientific collaboration. This research can give university administrators insight into increasing scientific collaboration among faculty members. The factors affecting it should be identified and planned to strengthen them

Nursing is one of the most important areas of medical sciences whose developmentsincluding its scientific publications can influence health care. Therefore, the aim of this study was toinvestigate nursing articles published from 2013 to 2018, and to provide a comprehensive view ofcommon topical clusters in this research area.

In this practical research,bibliometrics method and co‑word analysis technique are used. The study population includedall the articles in nursing area indexed in Web of Science from 2013 to 2018. The bibliometricssoftware, including BibExcel, UCINET, and SPSS was used to analyze the data.

Resultsindicated that the most frequently used nursing words in nursing research articles were “Qualityof life,” “Aged,” “Education,” and “Nursing.” Moreover, the pairs such as “Anxiety-Depression”,“Education, Nursing-Students, Nursing” and “Depression‑‑Quality of life” were the most frequentco‑occurrences. The use of hierarchical clustering led to the formation of seven topical clusters inNursing: “Nursing care for the Aged,” “Self‑care,” “Physical, emotional, and social support, “Motherand child health,” “Preventing nursing care,” “Nursing profession Research,” and “Quality of nursingcare.”

The growth of nursing scientific productions is an indicative of the importanceof this subject area in healthcare services; however, there is no balanced growth in various subjects. 

Every scientific activity needs to needs to know the previous related scientific activities so that its various aspects can be better investigated in order to obtain a richer intellectual heritage. So this article aims to identify and analyze the historical origins of ergonomics using two scientometric techniques named RPYS and RPYS-Co.

This applied research was conducted in a scientometrics method. The research data consists of 31239 articles in the field of Ergonomics which are indexed over the 20-year period (2000-2019) in the web of science database. After extracting all the references of these articles, the results were analyzed using the CRExplorer software.

Results showed that in the field of ergonomics, from 1700 to 2000, a total of 19 mutations occurred in the two periods of 1900-1700 and 2000-1900. The article "the information capacity of the human motor system in controlling the amplitude of movement" by Fitts (1954) was recognized as an outstanding and index work. According to RPYS-CO results the most co-citations with index work are related to the works of 1997 and 2004, which are on Fitts Law.

In the period of 1700 to1900 influential works were related to the field of psychology, biology and economics, and in the period of 1900-2000 influential works were related to the field of psychological theories, work environment and research methodology.

The novel coronavirus disease 2019 (COVID-19), which was first identified in Wuhan, China, in late 2019, has now spread around the world. It significantly affects the lower respiratory tract, and pneumonia is always present in patients with the severe form of the disease. Many studies have shown that the severity of COVID-19 is lower in pediatric populations. It is important to determine why infants and young children are not severely affected by COVID-19. By increasing our awareness of this disease, we can prioritize our limited health resources. Several theories have been proposed to explain such significant differences between the pediatric and adult populations with COVID-19. Some of them are: (1) the role of angiotensin-converting enzyme 2 (ACE2); (2) cross-immunity with other severe acute respiratory syndrome (SARS)-like viruses; (3) obtunded systemic inflammatory response in children; (4) more efficient T cells in them; (5) interactions of SARS-Coronavirus-2 (SARS-CoV-2) with other viruses in the mucosa of the lungs and airways; and (6) a hypothesis that COVID-19 proteins onslaught the heme on the β-1 chain of hemoglobin. The important thing to keep in mind is that the asymptomatic and mildly symptomatic pediatrics are crucial in the spread of COVID-19.

This study aimed to investigate the knowledge map in obstetrics and gynecology research using network analysis and visualization approaches through co-word analysis.

This applied research has been conducted with a scientometrics approach using the co-word analysis. The study population consisted of 57769 records on obstetrics and gynecology indexed in the Web of Science Database during 2014-2018.

The keywords "Pregnancy" and "Pregnancy-Preeclampsia" have been shown to have the highest rate of frequency and co-occurrence frequency in obstetrics and gynecology research, respectively. Hierarchical clustering leads to the formation of seven clusters, Clusters of "Caesarean", "Preeclampsia" and "Women's Cancer" are considered as adult clusters and "infertility" cluster is not a central cluster, but it is developed. It was also found that the clusters of "pre-natal screening", "menopause" and "pregnancy complications" are among the emerging or declining clusters.

Conclustion: 

The knowledge structure of obstetrics and gynecology revealed the status of research in this field which could be a guide for future researches. In the field of obstetrics and gynecology, issues related to infertility and its psychological problems need more attention from researchers.

Increasing massive amount of data and using them to improve the quality of management decisions are the problems of libraries and information centers. In the meantime, a powerful data mining tool can analyze data to predict and analyze user transactions and stop wasting time to use useful data from among massive data, identify valid patterns and unknown relationships, and help libraries in strategic decision-making and effective management assistance. This study using association rules technique, which is one of the data mining methods, seeks to analyze the transactions of user lending and discover their access pattern. In this cross-sectional descriptive study required data were collected from transactions of users of the libraries and information centers of Hamedan University of Medical Sciences and after preprocessing these data, the total number of 6636 user transactions was 132833 using a census method during a three-year period examined. The results of this study showed that most transactions and referrals with the score of 20.7±24.4 were related to the students and the highest delay and duration of loan respectively with the score of 884.3±1396.9 and 885.7±1765.3 related to the faculty members. Also, the rules derived from the Apriori algorithm showed by providing a users access pattern based on demographic information and determining subject dependence of information resources could be used as an appropriate pattern for analyzing and predicting user transactions.  Using association rules technique and implementing the Apriori algorithm, the best rules governing the data set were extracted. Therefore, using association rules technique can be designed as a book advisory system in libraries and information centers. Managers and policy-makers can also use these patterns and rules to align their supply and information resources with the real needs of their members, and can benefit greatly from library procurement, collection, management and services.

Identification of the effective organizational culture is one of the necessities of organizational culture management in any organization. This study is intended to design the effective organizational culture pattern of public libraries in Iran.  This is a qualitative study conducted by using the grounded theory method. By purposive sampling, 23 of librarians and managers of public libraries in 10 provinces were interviewed using depth and semistructured interviews. The data analysis was performed by theoretical coding (open, axial and selective coding). In the axial coding, core category was determined and in selective coding, final model was presented. Causes, intervening conditions, contexts, main strategies, and the main consequences of crisis management in libraries was presented in the model.  Based on the data from the research, 6 categories and 16 subcategories were identified as the dimensions and components of effective organizational culture in public libraries. The causal conditions preparing the ground for the explanation of the effective organizational culture in public libraries as the core category include: decrease in the number of users, reduction of employees' motivation, Failure to achieve the goals and roles, and the tendency for cyberspace. Conditions affecting the codification of strategies include: user's diversity, diversity of needs, being cultural, public and non-profit. Finaly, the outcome of the implementation of the said strategies are attracting users and social sublimity. The value of this paper is that it draws the attention of managers and researchers involved in the public libraries management to the fact that they must take into consideration the dimensions and components of effective organizational culture in managing the public libraries.

Despite continuous efforts to reduce human error in various systems, unsafe errors and behaviors are the main cause of incidents in the workplace. Hospitals are one of the places where human error events are abundant. Therefore, a systematic review of past studies is the best way to share the useful findings of studies and the availability of future studies in the field of human error. The electronic search of databases in Persian and English was done in three months from the beginning of the establishment of the databases. These articles were searched from PubMed, Scopus, web of science databases, and using the (or human) OR (human error) AND (health care OR health section) performance shaping factors (OR PSF). After searching, 6800 abstracts were searched. 5327 articles were excluded because they were not in line with the study objectives and inclusion criteria. Then 1473 abstract articles were independently studied by two researchers and the unrelated studies were excluded. 81 articles were independently reviewed by two researchers. Finally, 30 articles were fully in the study. The lack of skills and experience (26.6%), drug misconception (13.33%), negligence in treatment (10%), error of delay and error, and failure to implement the proper protocol for each share were equal (6.66%), security issues and Organizational culture and lack of complete patient examination, system failure, calibration and error selection, and diagnostic error and lack of information and error in implementing regulations (3.33 percent) also had a similar effect

Aim: Nursing is an important area in medical sciences whose developments can influence health care. One of the development indices in every field or profession is its scientific productions published in international journals. So, this study intends to investigate Iran’s Nursing articles from 2000 to 2016.
This research has been conducted by scientometrics approach. Research population includes all Iranian articles in nursing area indexed in Web of Science from 2000 to 2016 indexed in Web of Science in terms of number, productive and influential authors, international co-authorship, and subject world cloud and so on. For data analysis, a combination of bibliometric software, including NetRaw, BibExel and Cities are applied.
Findings revealed that during 2000-2016, Iran’s nursing studies have a growing trend. Ahmadi F, with 44 articles and h-index of 12, is the most productive and influential scientist in Iran’s Nursing studies. Iranian Nursing authors have many collaborative articles with their counterparts in USA, Australia, and Sweden, respectively. Moreover, qualitative research is the major research methodology within nursing studies. “Anxiety”, “Children”, “Breast Cancer”, and “Cancer” are the most frequent keywords in Iranian nursing studies.
The growth of nursing scientific productions is an indicative of the importance of this subject area in health care services; but, there is no balanced growth in various subjects. Meanwhile, the tendency of Iranian Nursing research is toward qualitative research which is due to the nature of the nurse-patient interactionism

Databases play a main role in education and research, so academics should be familiar with them and use them optimally. The aim of this study was to investigate the use and awareness of medical multimedia databases in integrated digital library by graduate students at the Hamadan University of Medical Sciences.
The current research is a descriptive survey and data collection tool is questionnaire. 260 people, as sample size, were selected by the stratified randomized sampling technique and finally 200 questionnaires were analyzed. And, the collected data were analyzed by means of descriptive statistics like frequency, frequency distribution, and mean using the SPSS16 software.
The results showed that familiarity rate of 85.1% of the Students with medical multimedia databases were unfavorable and 66.3% of the participants never used the multimedia databases. The most important barrier in using multimedia databases was the lack of notification about existence of the databases (74%).
Most of the graduate students were not familiar with multimedia databases at all and never used them. Considering the results of the current study as well as high costs spent on database subscription, it is necessary to pay more attention to the education and use of the databases by experts.

Job motivation is one of the factors factors influencing the behavior of librarians that can improve their performance. Considering that organizational culture is one of the factors influencing job motivation, the purpose of this study is to identify dimensions of organizational culture affecting job motivation of librarians in public libraries of Iran.
This qualitative study was conducted using content analysis. By purposive sampling, 19 people of librarians of public libraries in 10 provinces were interviewed using depth and semi-structured interviews. After extracting the primary codes, they classifyied in 3 dimmensions and 8 components.
Based on data dimmensions of organizational culture affecting job motivation are: Knowledge-oriented and Capability-oriented Culture (includes: professionalism and meritocracy, professional capability, use of technology, organizational learning), independency culture (inclides: non- politicization in the library, decentralization), and participatory and motivational leadership culture (includes: participatory management, motivational management). of public libraries in Iran shows that all of them have conducted by use of existing models. In view of nature and social roles of public libraries and broad impressive factors on them, these models have limitations to assess status of organizational culture in public libraries. So it is necessary to identify dimensions and components of effective organizational culture in public libraries of Iran and then manage the organizational culture on basis of this effective culture.
Dimensions and components of effective organizational culture resulted from this study can use as an ideal model for managing organizational culture or efforts to rule these cultural components in the public library of Iran.

Progressive enhancement and growth of population urbanized cities in the country, pay attention to how to control the spread of cities and taking steps in the direction of sustainable development in order to create a healthy city is essential. Humidity of the city ecosystem functions in recent years with the rapid increase in the population has faced that this would cause the city to expand and fitted up for peripheral environment. Therefore, the purpose of the necessity of paying attention to its future growth as well as the formulation of a suitable program, to develop suitable fitted the city is magnificent. In this study, has been trying to identify it with the influential factors and evaluation of optimum ways of physical development, the city of humidity using SWOT model. At this stage the development of the city, according to the index of the physical development of natural and synthetic evaluated for index. Methods of data collection and analysis of information and preparation of analytical-descriptive map needed more and using a soft-ARC GIS. derived from this research suggests that the lands located on the East and Southeast, the land for the town as well as within the context of the Bayer have academic centers, is considered the best of the physical development of the city's strengths can be fitted. Severe shortage of green space in the city, the user is not an appropriate system of networking for the city, did not focus on vertical construction compared to most of the population in the town centre and the lack of urban sewage system at the level of the entire city of the weaknesses.

One of the criteria showing the importance of a research area is the scientific products in that research area. The aim of the current study was to investigate the situation of scientific products on the topic of Patients’ rights indexed in ISI-Web of Science between the years 2000 until 2014.
The method used was descriptive-cross sectional with a Scientometrics approach. Thus, 347 documents of scientific products indexed in ISI-Web of Science with the topic of patients’ rights were studied using the search engine of this webpage between the years 2000 and March 2014. The collected data were analyzed with descriptive statistics.
The findings showed that the studied 347 documents had been published in six different formats, which 246 documents were of research articles, 73 documents were review articles and the rest were of other formats. Moreover, the countries the USA, England, and Germany had the most number of documents, respectively. Further, the American Journal of Comparative LAW, among journals, and Jansen, N, among researchers, had the most documents in this field. The scientific products experienced an upward trend after 2008.
One of the gaps in knowledge mapping in Iran, is low research activities in the field of patient rights; therefore, that results of this study can contribute to Iranian researchers to get more information about development of this subject area and even recognize top researchers working on the patient rights in order to establish more scientific communication with authors of this area.

Regular evaluation of websites in terms of structure, content and identifying the strengths and weaknesses of them provide an appropriate strategy for policy and decision making. Some of the most frequently used webometric indicators of evaluating are “visibility”, “web impact factor”, “rich files” and “size”. The aim of this research was evaluation of hospitals’ Websites of Hamadan University of Medical Sciences based on webometrics indicators in 2014.
The study was done by webometrics method. The population under study was all of hospitals’ websites of Hamadan University of Medical Sciences. Data was collected by Google search engine.
The results indicate that website of Ekbatan hospital in terms of “visibility” and “absolute WIF” and website of Shahid¬Beheshty hospital in terms of “size”, “traffic rank” and “rich file” ranked first. In overall ranking website of Shahid¬Beheshty hospital ranked first and website of Valyeasr hospital in Toyysrkan ranked at the end.
Results show that Hamadan University of Medical Sciences have little presence on the Web. Given the importance of websites in information, and dominance of cyberspace on the organizations services, it requires that the websites officials do further actions to enhance the quality and quantity of their websites.

Flows of natural hydro-environments are usually turbulent and mostly stratified، like the flows in lakes، reservoirs، estuaries and atmosphere to name a few. In stratified flows due to the buoyancy forces، the turbulent stresses are usually non-isotropic. Therefore the accuracy of the numerical simulations for such flows is highly dependent on the turbulence model and the implementation of non-isotropic stresses. The hydrodynamic model deployed herein is the 2DV WISE (Width Integrated Stratified Environments) numerical model. In this paper an explicit algebraic Reynolds stress model together with an explicit algebraic scalar flux model have been developed and implemented in the original hydrodynamic model. To validate the EARSM turbulence model، lock release tests have been simulated for saline and dense stratified flows. The predicted values of the evolution and the front head position of the stratified flow، and the velocity profiles simulated by EARSM model have been compared against the measured values reported in the literature and the predicted results of the buoyant k-ε model originally included in the hydrodynamic model. The comparisons indicated good performance of the EARSM turbulence model and showed its superiority compared to the k-ε turbulence model in these regions.

In this paper, the effect of the position of the pin relative to tool shoulder has been investigated in the friction stir welding process on aluminum 5083. Firstly, the preparation of the process is performed that includes tool, work piece fastened to dynamometer by special fixture and milling machine. Test is performed by tool with pin coaxial with the axis of tool shoulder in this process. So, the tool enters the edges of joint location and moves along joint line. Results are heat generation, severely plastic deformation and material displacement in joint location and this leads to complete joint of the edges. Force and temperature in joint region are measured during the process. Then, the parameters of the shape and the position of tool pin change and joint test is performed. The shape of the tool changes by offsetting the axis of tool pin relative to the axis of tool shoulder with different designs and the results of welding forces and tool temperature and mechanical properties are considered.
