Artificial intelligence (AI) is becoming an emerging tool in medicine and more recently in the operating room. Existing research mainly focuses on the possibilities and future expectations of AI in surgery. The aim of this study is to provide a systematic review of current applications of AI to support processes within the operating room. Articles describing applications of AI in surgery were reviewed. Several applications of AI in the operating room were reviewed, including surgery duration prediction, gesture recognition, intraoperative cancer detection, intraoperative video analysis, surgical nodule detection, and automated bone registration in orthopedic surgery. Current applications of AI are still in their early stages but have great potential to improve surgical accuracy, provide guidance in decision-making, and increase surgical safety. However, the integration of AI in the operating room faces several challenges, including regulatory issues, ethical considerations, and the need for clinical approval. Future research should focus on clinical validation, legal considerations, and pathways for implementing AI in the operating room.

A new photonic crystal fiber (PCF) biosensor based on surface plasmon resonance (SPR) phenomenon is proposed. In terms of chemical stability of the active plasmonic material gold (Au) and the sensor layer outside the fiber structure, it is used to simplify the sensor configuration. The proposed sensor can detect unknown analytes flowing on the metal surface or dripping on the outer surface of the metal layer. The proposed sensor consists of symmetrical circular air holes. Two small air holes are used in the second ring. which helps to generate the field and also helps to adjust the phase matching between the guided state of the nucleus and the surface plasmon teppolaritons (SPP). Surface plasmons are excited along the metal surface by the guided mode of the leakage-like Gaussian kernel. The guiding properties and the sensing performance are numerically investigated by the Finite Element Method (FEM). A perfectly matched circular layer is used to absorb the radiation towards the surface. The sensor offers a maximum sensitivity of 1000nm/RIU with a sensor resolution of less than 1×〖10〗 ^(-4) RIU.The proposed sensor design shows promising results that can be used in the detection of biological and biochemical analytes.

The purpose of this research is to investigate the factors affecting the unfulfilled need of having children of women living in Tehran. The research method was a survey and the data was collected using a questionnaire. The statistical population included married women aged 30-44 in Tehran in 1400, of which 400 were selected as a sample using a multi-stage cluster sampling method. The findings show that most people consider the ideal number of children in the family to be two children. The results of bivariate analysis showed the unfulfilled need of women to have children and the variables of respondents' age, age at first marriage, age gap between couples, length of marriage, number of children, religious adherence, attitude towards the value of children, social network norms, individualism and control perception. Behavior has a significant relationship. The results of the multivariate regression also showed that in the final model, the variables of women's attitude towards the value of children and the level of religious adherence of women have a direct, positive and significant effect, and the variables of the number of children of women, the attitude of women towards the norm of the social network regarding the increase of children. and individualism have a direct, negative and significant effect on the unestimated needs of women.

The aim of this study was to investigate the causes and factors affecting the unfulfilled childbearing intentions of women living in Tehran. The research method was survey and data were collected using a questionnaire. The statistical population included women aged 30-44 married in Tehran in 1400, of which 400 were selected as a sample using multi-stage cluster sampling. The findings show that most people consider the ideal number of children in a family to be two. The results of bivariate analysis showed that between unfulfilled intentions of women having children and respondents age, age at first marriage, age difference between couples, duration of marriage, number of children, religious affiliation, attitude towards child value, social network norms, individualism and control Perceived behavior has a significant relationship. The results of multivariate regression also showed that in the final model, the variables of women's attitude towards child value and women's religious adherence have a direct and positive effect, and significant and the number of female children variables, women's attitude towards social network norm regarding Increased childbearing and individualism have a direct and negative negative effect on women's unapproved intentions. Perceived control variables of women's behavior, age, age of marriage, duration of marriage, age difference of couples indirectly affect women's unfulfilled / fulfilled intentions by having an effect on other variables.

Paying attention to the diversity of teaching-learning strategies is the most effective tool. Electronic content production is an effective teaching-learning process based on new scientific findings, which is used to increase the efficiency of education, due to the increasing development. The use of education technology, in this research, according to the researches, the advantages and limitations of using education through electronic content were studied. In the present age, technology can help education and put an end to the repetitive process of questions and answers. Improve the deep quality of sustainable learning and teaching. This research is based on a field study with the aim of investigating the factors affecting the development of the electronic content market at the level of Rasht Advanced Skills Training Center. For this purpose, a questionnaire was prepared that considered the main features of e-learning and important factors in content production. By selecting active workshops of Rasht Advanced Skills Training Center in face-to-face or electronic sessions, they were completed and the desired information was collected. Then, by averaging the answers given, the existing challenges and shortcomings were identified and solutions were proposed to address them.

The purpose of this research, which has been done through research method, is to provide solutions to attract trainees and solve the existing problems in teaching 18-month plan courses. This research has conducted surveys of 18-month trainees over a long period of time. Then, by examining the existing problems and providing suggestions, a number of suggestions that can be implemented and planned, have been applied in subsequent periods. After reviewing the problems in the 18-month plan and conducting a survey of trainees, we came to the conclusion that the problems we listed at the beginning of the work in consultation with our colleagues in this area are largely correct and consistent with the trainees' opinions. Therefore, in consultation with our expert colleagues and implementers of the 18-month plan, we prepared a list of suggestions to solve the problems of these courses. Also, in order to analyze the information using descriptive statistics as well as qualitative reports that are the result of the instructor's experiences, the research findings are collected and the main methods of collecting information are the instructor's observations, interviews with trainees and also the use of trainees's surveys. The findings of this study show the process of improving the trainees' satisfaction with the 18-month plan training courses and increasing the interactions between the skills of the graduates of this course and industries.
