Background and Aim: Considering the increasing use of dental implants in replacing lost teeth, the odds of failure over time in this treatment are inevitable, as with other dental treatments; thus, it requires careful and regular follow-up. Accordingly, the present study aimed to evaluate the awareness and attitude of general dentists about the follow-up of the dental implants to create baseline information to schedule future workshops concerning dental implants.
Methods & Materials: In this analytic cross-sectional study, 98 general dentists of Arak City, Iran were evaluated. Questionnaires were designed in 3 sections, as follows: demographic, awareness, and attitude. After checking the validity and reliability of the questionnaires, they were distributed among the research participants. The obtained data were analyzed using descriptive analysis, Chi-squared test, and Independent Samples t-tests. The significance level was considered 0.05.
Ethical Considerations: This article was approved by the Ethics Committee of Arak University of Medical Sciences (Code: IR.ARAKMU.REC.1397.283).
Results: The average score of awareness of the questionnaires was equal to 10.8 (based on the score of 0-19); the mean score of attitude was measured as 12.8 (based on the score of 7-21). Fifty-Three of the explored dentists had performed implant treatment, whose awareness and attitude toward implants follow-up were significantly higher than those of the dentists who did not perform such treatment (P=0.0001). Work experience presented no significant effect on the examined dentists’ awareness and attitude (P>0.05).
Conclusion: General dentists have low awareness and attitude about implant follow-up. Follow-up plays an important role in the long-term success of implant therapy; therefore, dental education/retraining programs should be reviewed in this field.

Background and Aim: The human coronavirus is a member of the Coronaviridae family and causes upper respiratory tract infections. Despite repeated severe epidemics and the lack of appropriate antiviral drugs, not much progress has been made on the epitope-based vaccine designed for HCoV. 
Methods & Materials: The method of this study was to select the spike corona virus protein sequence from NCBI, retrieve the protein sequence and determine the T, B epitopes required to produce the chimer vaccine, evaluate the antigenicity and allergenicity and toxicity of the selected epitopes, respectively. Different servers were designed to configure the primary chimer composition of the epitope vaccine. Then, the chimer vaccine was evaluated in terms of structure and connectivity to B cells and MHCI and II compounds, and the two-dimensional structure and position of amino acids and bonds in the immunogenic model were studied, as well as the physicochemical and stability of the model vaccine by some other servers. Finally, it was tested for binding against HLA molecules using silico docking techniques to investigate the interaction with the epitope.
Ethical Considerations: All ethical principles are considered in this article. Participants were informed about the research objective and its implementation stages. They also made sure their information was confidential. The principles of the Helsinki Convention were also observed.
Results: The results showed that the immunogenic construct created in terms of two-dimensional and three-dimensional structure and the position of amino acids and bonds in the model of immunogenic structure, toxicity and allergenicity and antigenicity were in good condition. And had stability (instability index 33.93) and favorable half-life and suitable physicochemical conditions.
Conclusion: In general, the immunogenic structure that was prepared in this research process could have a favorable interaction with some components of the immune system (HLA) in the docking process, which indicates the optimal identification of this structure by the humoral and cellular immune system and stimulation in In order to produce immunity in the body of the host, of course, more reliable proof of it requires clinical phase processes.

Background and Aim The occupational environment, the type of work overload or underload, physical risks, how individuals adapt to the workplace, and face the family - work constitute the sources of stress or occupational distress. Job stress emerges as the duties and tasks assigned to people are more than their abilities. This study aimed to investigate the relationship between stress management training and work ethics of employees.
Methods & Materials This research was an applied study in terms of purpose, a mixed exploratory (qualitative and quantitative) study in terms of data, a content analysis (qualitative stage) and  cross-sectional survey (quantitative stage) in term of conduct. The study population in the qualitative section comprised experts (Experts in Psychology, Educational Management, and Social Medicine) according to the inclusion and exclusion criteria. In the qualitative section, the study population included experts and managers who had received stress management training. Sample size and sampling method in qualitative part was based on the principle of theoretical saturation, resulting in 12 people using purposive sampling method. In the quantitative part, the sampling was based on the Cochran’s formula, resulting in 220 people who were selected using cluster sampling method. 
Ethical Considerations This barcode research was presented to the Ethics Committee and registered in the system (IR.IAU.TNB.REC.1400.121). 
Results The results showed that to deal with stressful situations, three basic strategies of event-focused coping, anxiety-focused coping, and avoidance-focused coping strategies can be used for stress management training models. Overall, the components presented for coping with stressful conditions have the necessary and appropriate validities. All three main coping strategies (event-focused, anxiety-focused, and refusal-focused) are suitable for explaining and fitting. So, they all are reliable and confirmed in the current research questionnaire of coping with stress.
 Conclusion Strategies for coping with stressful situations have a different effect on people’s professional work ethics so that the event-focused coping strategy has a significant positive relationship with professional ethics. On the other hand, the anxiety-focused and avoidance-focused coping strategies have negative and decreasing relationship with professional ethics. The more emphasis on the event-focused coping strategy, the more would be the professional ethics of individuals and the more emphasis on the anxiety-focused and avoidance-focused coping strategies, the less would be the professional ethics of individuals..

Introduction: Traffic accidents are a principal challenge in the injury and death of people in Iran and many other countries, which has made the formulation of necessary strategies and planning for inter-sectoral cooperation to prevent and reduce traffic accidents undeniable. Therefore, this research was conducted to investigate the dimensions of inter-sectoral collaboration in preventing traffic accidents in Iran.
Methods: This research is a qualitative study that was conducted in 2023. In this study, sampling was done in a targeted manner, and 15 people from the statistical population were interviewed. The statistical population of the research at this stage included executive managers, traffic police, field activists, and public institutions active in the field of traffic accidents in Central Province and Tehran, who, due to the relevance of their job field, were informed or participated in intersectoral cooperation in line with the management of accidents and traffic accidents were included in the study. Data were collected and analyzed through structured interviews, and their coding was done with the help of MAXQDA 11 software.
Results: The study identified and extracted eight main dimensions of intersectoral cooperation in preventing traffic accidents. These dimensions include laws and law enforcement, research and development, information and data management, internal and external coordination, crisis management, education and awareness, roads, and vehicles.
Conclusions: Providing platforms for promoting the development and expansion of inter-sectoral cooperation in accident prevention and traffic accidents can have various benefits, including long-term social, political, economic and, well-being. Therefore, based on the findings of the research, it is suggested to design an intersectoral cooperation model for the prevention of accidents and traffic accidents so that traffic accidents can be reduced to the minimum possible with proper planning and design so that we can witness the highest level of effectiveness and efficiency in this area.
