The world population is rapidly aging and according to the World Health Organization report, the number of people aged 60 and over will reach two billion in 2050. Because of this, an important issue is emerging. It defines a new generation of healthcare platforms with the ability to monitor people's quality of life. In recent years, an increasing interest in product-service systems has been recorded in many industries. Various companies have recently introduced new services related to their products to meet customers' new and higher expectations. This interest increased with the introduction of new technologies and developments brought about by the Fourth Industrial Age. In this research, after presenting an introduction about the health-oriented smart product-service system, its importance has been examined for the components and indicators of the health-oriented smart product-service system for older adults.

In this qualitative study, by analyzing and reviewing the content of the studies conducted regarding the health-oriented smart product-service system and by obtaining the opinion of a focus group including 10 managers and experts in this field, the conceptual model of the smart product-service system The health of older adults was presented.

According to the review of the literature on the subject and the study of past research, the components and indicators of the smart health-oriented product-service system in a comprehensive manner (taking into account all the models and opinions raised in this field) present and the components of the system consisting of 10 main components; Actors and integration network, cost of system implementation and management, cloud platform and platform, physical platform, connectivity, personalization and customization, experience management and user interface (UI, UX), user feedback systems, drug management and clinical review. It is an educational guide and rules, and each component's indicators and system parameters are also mentioned.

The most important achievement of this research is a general initial model for this, which can be used as a basic architecture and structure by public and private organizations in the field of health, and especially technology-oriented startup companies to design a health-oriented intelligent product-service system. Also, the design of smart health-oriented product-service systems based on the cognitive factors of older adults and insurance systems based on the components and indicators proposed are topics for future research.

Knowledge-based industrial organizations need to take advantage of intellectual and knowledge capital in order to be a leader in the field of knowledge-based production. The knowledge-oriented approach of the future Ministry of Defense, on the one hand, and the development of new defense products according to the environmental conditions, on the other hand, has caused the need to identify and manage intellectual capital in the Ministry of Defense to be felt more than ever. Accordingly, it can be stated that the transformation in the nature and form of battle and the change in the nature of military threats and the formation of the fourth wave defense industries increase the importance of paying attention to a systemic approach in measuring and managing intellectual capital for the Ministry of Defense. Therefore, the main goal of this research is to design a native model of intellectual capital in order to measure it in the Ministry of Defense. The research method is mixed and in the qualitative stage, after conducting exploratory interviews, local dimensions, components and indicators were identified using the data foundation method, and after aggregating with the dimensions, components and indicators obtained from the literature, using Delphi method in two stages, the final model of the research will be calculated. Also, in the quantitative phase of the research, inferential statistics will be used to validate and measure the existing situation in the industrial organizations of the Ministry of Defense

Probiotics are one of the most effective methods for replacing antibiotic therapy. Aquatic animals' quality can be enhanced through the use of probiotic products in various ways. The right choice of probiotics is crucial because unsuitable microorganisms can lead to negative effects on the host. A microbial consortium is not only a mixture of different strains, but also consists of different populations of microorganisms that interact with each other. The advantages of a bacterial consortium are the synthesis of complex molecules, such as extracellular enzymes. The use of a probiotic consortium that provides multiple beneficial functions and it is considered a new generation of probiotic products. Understanding the current interactions among consortium members and the dynamics of existing populations is essential for designing a microbial consortium with industrial applications.

Today, with the expansion of the use of smart phones, every passenger is also equipped with a small GPS device. This issue has provided a new range of information, the analysis of which will help to improve the performance of the taxi transport fleet. However, the survival and success of businesses that provide online transportation services depends on attracting new customers and maintaining previous customers, and with the growing desire to use these services, it seems necessary to investigate the factors affecting the profitability of these companies. The present research investigates the effect of online service level and perceived risk on the intention to use online services. The statistical population of this research is the customers of Snap smart transportation system in Tehran, who used the online services of this company. The results of the analysis of 419 questionnaires collected using the structural equation modeling method showed that the level of service (pre-purchase services and services related to transaction and payment) has a positive effect on the intention to use online services, and perceived risk has a negative effect on the intention to use of online services. Finally, suggestions for attracting and retaining customers are presented to internet business managers.

The spread of the Covid-19 disease for the past three years has forced many organizations and governments to formulate and implement ways to achieve the ultimate goals of the organization. In this, the role of technology is very important. With technology, all activities can continue. This study explains that technology, organizational culture and job satisfaction in the national hospitals of one district of Tehran are motivations to improve performance, especially during the epidemic.

181 questionnaires were distributed among employees. Respondents must meet the following criteria: at least one year of work experience and at least a diploma. The dependent variable is employee performance. The independent variables are organizational culture, motivation and job satisfaction. Intervening variable is information technology. Due to the presence of intervening variables, research hypotheses were analyzed by PLS factor analysis method and using SPSS version 19 software.

The results of the research show that organizational culture, job satisfaction, and motivation have a significant positive effect on employee performance, and also organizational culture and motivation through information technology have a significant impact on employee performance.

The results of the study can be used as a basis for designing business strategies to improve the performance of employees in a competitive environment to improve the credibility of hospitals.

Since the onset of the Enlightenment in the early 18th century, and the subsequent establishment of museums, galleries, and private collections, the acquisition of cultural artifacts to populate these institutions became imperative. However, this period also witnessed the emergence of counterfeit works, crafted in collaboration with specialists across various disciplines. A crucial inquiry arises regarding the identification of the methods and techniques employed by forgers, the recent surge in counterfeit production, and the detrimental impact of such works on archaeological studies and museum activities. This paper aims to provide a comprehensive examination of counterfeit works, tracing their origins in Iran, elucidating the typology of counterfeit objects, detailing the methods of forgery, and analyzing their dissemination to target audiences. Through a combination of library research and field studies, this investigation reveals that counterfeit works exploit historical and cultural significance, often leveraging contemporary scientific knowledge. The lack of precise discernment by target groups regarding these counterfeit works has facilitated their creation and distribution across three primary levels: 1) individuals seeking to amass wealth, 2) domestic enthusiasts of historical and cultural artifacts, and 3) galleries and foreign museums.

From the beginning of the discussion of commercialization of technology in the country's research institutions, regardless of their size and specialized field of activity, the problem that has been constantly faced by the managers of these centers is that despite the many achievements and research results obtained by knowledge-based companies and research institutes; Most of them have not been successful in commercializing and delivering the results of these researches to the final consumer in the market and society and generating a good income. The present research was conducted with the aim of identifying and prioritizing factors affecting the commercialization of products of knowledge-based companies in the field of biotechnology. The statistical population of the research is 19 members of academic staff and managers in the field of commercialization of products of knowledge-based companies in the field of biotechnology and they have a visible work experience. The current research is applied in terms of purpose and descriptive in terms of data collection method. To collect data, qualitative methods of interviews with experts and content analysis were used, as well as a questionnaire tool for prioritizing factors using the Danp method. The results of the research showed that 6 government criteria, economic factors, legal factors, senior management, project management and organizational factors were identified as effective factors on technology commercialization. Then, these criteria along with 22 related sub-criteria were weighted using Danp technique. Finally, the results of the research indicate the high importance of the role of organizational factors (flexible organizational structure and innovative organizational culture) on the commercialization of the products of biotechnological knowledge-based companies.

Police command is one of the institutions involved in the establishment, maintenance and increase of security, which played a fundamental role in the Islamic revolution and in realizing its ideals. Considering the diverse and extensive missions and the threats that are directed at the police command in order to fulfill the assigned mission, the implementation of these tasks requires a revolutionary approach.

The method of collecting information is documentary, the present research is fundamental in nature and developmentally applied in terms of purpose, qualitative content analysis was used to develop a model of revolutionary management in Faraja; the data includes the Supreme Leader's speeches about Faraja, which were categorized and analyzed.

After finalizing the categories, their relationships with each other were examined and the research model was presented. The second layer consists of ten categories, including: Patience, bringing authority and love to people and paying attention to the position, mission and capabilities of Faraja, security-creating, transformational, interactive, law-abiding, wise, healthy life and enemy. Science and at the end of the category that connects the two layers is the category of "thinking based on science, reason and determination". So that from the heart of the first layer, a kind of methodology is obtained, which is a methodology centered on science, reason and determination, which leads to the second layer and the categories of revolutionary management, together with the production of science. and this science is considered as an accumulation that again forms a new movement in the direction of creating new layers of revolutionary management and this movement is constantly repeating itself; If Faraja has a comprehensive revolutionary management model, it can show better performance in the direction of maintaining security, and make an effective contribution in the direction of the full realization of Islamic goals.

Explaining the quality of employee-organization relations in unplanned changes resulting from an event such as an epidemic in the workplace is an important concern. With this aim, this article presents a model on the effect of transparent communication within the organization on the quality of employee-organization relations. From the point of view of use, purpose and time, this research is applied, exploratory and a cross-sectional study, and in general, it is a quantitative research with a survey and gathers data by a questionnaire tool that is in the form of a matrix and with scalable closed questions resulting from literature review and interviews. The statistical population includes the employees of one of the subordinate organizations of the Ministry of Defense and Armed Forces Support, and the sample size, using the available method, was 95 people. Structural equation modeling and SmartPLS software have been used to test the hypothesis. The findings of the research include that clear communication within the organization directly and through the mediating variables of "control exposure strategies" and "perceived uncertainty" affects the employee-organization relationship in unplanned changes. It can be concluded that transparent communication methods provide the possibility for employees to participate in the decision-making process and receive sufficient and reliable information during unplanned change, to equip themselves with the tools to face such changes. Also, clear communication practices help manage unplanned changes by reducing uncertainty.

Risk management in today's organizations has become a part of the strategic approach to achieve projects, Failure to pay attention to the risks in any project can cause threats in the implementation of the project, so that the consequences of those factors directly affect the time, cost and quality. military organizations, as the main elements of defense, are obliged to protect the country from foreign threats, Therefore, they should identify potential risks, plan for proper management and avoid unexpected decisions. Considering the importance of military equipment projects and referring to the lack of full transfer of construction technologies, the lack of reconstruction from the manufacturing countries, and the existence of sanctions, this research aims to identify, evaluate and rank the risks affecting the reconstruction of a Armored combat vehicle. The risks were identified by reviewing articles and the Delphi method, and the Multimora method was used to rank them. In order to weight the indicators, the best-worst method was used. Also, a questionnaire was designed for implementing the multi-mora method And it used the Likert method with the opinion of 5 activists in the field under discussion. The results indicated that the issue of quality is more important than other indicators. Also,the absence of manufacturing technologies and lack of the technical experts are the most important, and the lack of tools and recognition of the existing capabilities are the most worthless risks. This research can help to develop and create opportunities for military organizations to carry out such projects.

The transformation in the nature and form of battle and the change in the nature of military threats and the formation of the fourth wave defense industries increase the importance of paying attention to a systemic approach in measuring and managing intellectual capital for the Ministry of Defense. Therefore, the main goal of this research is to design a native model of intellectual capital in order to measure it in the Ministry of Defense.

The research method is qualitative and in this method, after conducting exploratory interviews with experts and researchers in the field of intellectual capital, dimensions, components and native indicators were identified using the data foundation method and using the Delphi method in two stages. The final sample of the research was calculated.

This model includes the dimensions of human capital, structural capital and social capital and will be implemented in the Ministry of Defense in order to measure the state of intellectual capital.

The results of the research show that this model includes the dimensions of human capital, structural capital and human capital. Also, this dimension has 13 components and 72 indicators.

The Internet of Things (IoT) essentially refers to the connectivity of various objects through the internet to facilitate a more efficient and intelligent experience. However, due to the emerging nature of this technology in Iran, instances of its full deployment in service organizations, including hospitals, are rare or infrequent. Therefore, the aim of this study is to identify the key success factors for the deployment of IoT and assess the readiness for implementing this technology in Milad Hospital, Tehran.

This research is a descriptive-survey study conducted in two phases. In the first phase, 30 key success factors were identified through a review of previous studies. In the second, survey phase, 93 managers and staff members of Milad Hospital formed the statistical population, and data was collected through a researcher-made questionnaire. The comparison of the current and ideal states of success factors for IoT implementation, and their ranking, were done using the t-test and Friedman test in SPSS software.

Based on this study, factors such as information technology, organizational culture, organizational structure, and human resources were identified as the most crucial for successful IoT deployment in the hospital. Additionally, the results showed that there is a significant gap between the hospital's current state and the desired state for IoT implementation in these identified areas.

Successful implementation of IoT requires enhancement in readiness, both in terms of technological and organizational-cultural infrastructures

The current research was conducted with the aim of using blockchain in human resource management of educational organizations. The statistical population of the research is 10 people who are experts in the field of human resources and know the basics of technology and blockchain and have a visible work experience.The current research is applied in terms of purpose and descriptive in terms of data collection method. To collect data, qualitative methods of interviews with experts and content analysis were used, as well as a questionnaire tool for prioritizing factors using the Denap method. After reviewing the literature and interviewing related experts, nine main factors were identified in line with the applicability of blockchain in human resource management of educational organizations. Following the prioritization done in the studied university, it showed that one of the main reasons for using blockchain in human resources management is blockchain-based human resources records. As mentioned in the research literature, blockchain makes both the job seeker and the employer clearly consider the records and then make a choice. The results of the research showed that increasing efficiency and productivity (accurate decision-making - optimal services-...), reducing human resource management violations and errors, and maintaining and securing data based on blockchain have the greatest impact in the application of blockchain. China has in human resource management. On the other handHuman resource records based on blockchain (trust-convenience-fast recovery-fast access-simultaneous access-accuracy-reliability-...), transparency and data integration in blockchain are the most effective factors.

 The primary purpose of this manuscript is to present the knowledge management strategy compilation model based on Business strategy.

This research uses quantitative and qualitative methods to extract the key components of the organization's knowledge strategy from descriptive and analytical (qualitative) methods. Quantitative and statistical methods will be used to validate the model.

The research results showed that to develop a knowledge strategy model since knowledge management processes are carried out in the organization's context, they are under the influence of the organization's background. The organization field includes 1) knowledge management enablers such as organizational factors (such as structure and culture) and technology, and 2) knowledge management drivers such as business strategy and intellectual resources of the organization. Also, knowledge and learning should support the organization's business strategy.Originality/Value: The focus of knowledge management so far is more on knowledge enablers, such as Creating a suitable cultural structure for the creation and sharing of knowledge or the development of technologies to facilitate these matters, and much less emphasis on the drivers of knowledge management such as; the mission and strategy of the organization has been realized, which makes knowledge management, although it works very well in its defined area, ultimately does not have a favorable effect on the performance of the organization. This research aims to design a model to develop a knowledge strategy and establish the correct relationship between knowledge strategy and business strategy. Then, the validation of the model will be done by obtaining experts' opinions.

Knowledge management is a process that helps the organization to find, select, organize and publish important and useful information. This article aims to investigate the effects of knowledge management in the organization and identify the factors affecting the performance of intellectual capital in one of the hospitals in Tehran.

This research is an applied research in terms of its purpose and descriptive and correlational in terms of data collection method. After studying the background of the subject and examining the existing models regarding the management of knowledge and intellectual capital and the formation of the theoretical framework, the important variables of the research were identified and the hypotheses of the research were determined. The statistical population of the research includes researchers and employees of one of the hospitals in Tehran. They were selected as a sample using the Krejs and Morgan table and based on the simple random sampling method (n=80). The tools used in this research are Proust et al.'s knowledge management questionnaire (2000) and Botis' intellectual capital (1998).

The validity of the questionnaires was confirmed by 10 experts, and through Cronbach's alpha test, the reliability of both questionnaires was 0.78 and 0.80, respectively. The results of the data analysis showed that each of the dimensions (evaluation, goal, identification, acquisition, development, sharing, maintenance and use) of knowledge management directly had a positive effect on the performance of intellectual capital.

From the above findings, it can be concluded that in order to improve intellectual performance in their organization, each of the organizations should make necessary plans to improve each aspect of knowledge management.

Prioritizing the impact of intellectual capital factors of the Ministry of Defense.

The method used in this research was quantitative in terms of nature of data, applied in terms of purpose and descriptive research in terms of data collection. In this research, the dematel questionnaire tool was used to collect data and the danp technique was used to prioritize the criteria. All steps are done using EXCEL software.

The number of 3 criteria and 13 sub-criteria of intellectual capital were weighted using the danp technique. Finally, the finding of the research indicate the high importance of the human capital criterion in promoting the authority of defense power, and social capital and structural capital are the next priorities. Idealist, authoritarian, relational sub-criteria are respectively the most important in the.

One of the key issues of today and the future of the country's armed forces is not only the use of expert and committed human capital to create or develop advanced technologies and capabilities, but the armed forces and especially the Ministry of Defense need to design an efficient model for the use of human capital and special talents in line with Achieving groundbreaking innovations and developments shows the importance of addressing intellectual capital and prioritizing its factors.

The present research was conducted with the aim of investigating the effect of spiritual leadership style on employee loyalty with the role of moderating trust in the organization. The statistical population of the research is the employees of the airport and air navigation company, and the sample size was obtained using the Cochran formula equal to 284 people by simple random sampling method.

The current research is applied in terms of purpose and descriptive-correlation in terms of data collection method. And three localized questionnaires of spiritual leadership style, employee loyalty and trust in the organization were used as research tools. The reliability of the spiritual leadership questionnaire was estimated using Cronbach's alpha coefficient equal to 0.82, employee loyalty equal to 0.82 and trust in the organization 0.79. Also, structural equations were used to test the hypotheses.

The research results showed that spiritual leadership has an effect on employee loyalty, the effect of spiritual leadership on loyalty is equal to 0.41, as well as the sub-components of spiritual leadership (spiritual vision, hope and faith, organizational commitment, love for one another, membership, meaningfulness and performance feedback) have an effect on loyalty,

The results of the research showed that the effect of trust in the organization on employee loyalty is significant, path analysis based on structural equations confirmed the moderating role of trust in the organization between the two variables of spiritual leadership and employee loyalty.

Implementation of the strategic plans will lead to building culture and institutionalization of participatory management, process management and strategic thinking in management of organizations. This paper presents a heuristic method for establishing and achieving the goals of knowledge management at Project-based contracting companies through strategic planning and balanced scorecard methodology. In this research, strategies have been planned and monitored by Balanced Scorecard tool. This tool will establish a balance between organization approaches and goals, including desired goals of knowledge management and its approaches. Sepasad group have been used strategic management process in order to integrate other organizational improvement systems and activities.

The model presented in this paper is exclusively for implementing knowledge management through Balanced Scorecard in project-oriented construction companies.

With the prevalence of COVID-19 in the world and the sharp increase in deaths due to it, hospitals are in dire need of changing their situation and raising their preparedness in the face of the crisis. Therefore, the aim of the present study is to prioritize the factors related to the readiness of hospitals against COVID-19.

In this descriptive-survey study, first, by reviewing the literature, factors related to hospital readiness were extracted. Then, in order to validate these factors and reach the consensus of the expert group (40 physicians and nurses involved in the front line of the corona), the Delphi method was used. Finally, the identified indicators were ranked and prioritized using the SWARA (Stepwise Weight Assessment Ratio Analysis) technique.

The literature review and Delphi method led to the identification of 18 indicators related to hospital readiness, the most important of which were the number of staff, medical equipment, education and work experience, emergency network and manpower readiness, respectively.

Considering the severe vulnerability of hospitals to possible corona peaks, based on the results of this study, the condition of hospitals can be evaluated from five perspectives: hospital building, medical equipment, communication equipment, transportation and personnel, and necessary measures should be taken to eliminate their shortcomings.

The purpose of the upcoming research is to identify the dimensions and components of open innovation in knowledge organizations (universities) and provide a model for moving from closed innovation to open innovation with a knowledge management approach in these organizations, considering the effectiveness of each of The dimensions are The statistical population consists of 10 members of the practical board who are knowledgeable about the basics of knowledge management and innovation, who were selected in a targeted manner.

The research tool is the interview in the qualitative part and the questionnaire in the quantitative part. After identifying the components and dimensions of open innovation in academic organizations (universities) and selecting a number of these dimensions according to the opinions of the expert team, these dimensions were examined using the DANP decision-making and prioritization method, and the intensity and effectiveness of each of the factors Was obtained.FindingsThe results of the analysis showed that the number of 75 components was reduced to 30 after merging similar components and categorizing them, then with the opinions of the 8-dimensional expert team, it was identified for the implementation of open innovation in knowledge organizations.

In this model, the three components of management support and commitment, organizational culture and training and skilled workforce have been identified as the most important influencing factors, which also influence each other. More attention of organizations to the components of support and commitment of managers and organizational culture, according to the presented model, will cause it to indirectly affect them even with less attention to other components and finally cause The organization was promoted in the desired field. Forming departments to monitor the factors mentioned in the category of components, because promotion starts from the lowest levels and causes changes at the highest levels of the organization.

In a knowledge-based economy, there are successful organizations that use this intangible asset better and faster. Research shows that knowledge is the most valuable and strategic resource in today's business environment. In this regard, knowledge management and intellectual capital has become one of the main characteristics in universities, whose main task and purpose is to produce and disseminate knowledge. Managers know that they have to manage the learning process and measure the results. However, organizations do not have the appropriate knowledge model and measurement tools to evaluate their learning outcomes. Therefore, in this research, an attempt is made to design a suitable model for measuring structural capital (as one of the main components of intellectual capital). The present study is applied in terms of purpose and combined in terms of data collection method. First, a conceptual model of research was extracted from literature studies and interviews with technical experts. A sample of 9 people was selected by qualitative method using snowball method. Also, 70 questionnaires were distributed among the available professors and experts in a simple random method to evaluate the extracted indices and the existing model. Finally, using various tests (reliability, convergent validity, diagnostic validity, regression analysis, factor load analysis), the validity of the indicators was examined and in order to confirm the model, the structural equation model and PLS software were used.

 Due to the increasing importance of intellectual capital in today's companies, many researchers are looking for ways to measure intellectual capital and examine its relationship with the performance of organizations. The main purpose of this study is to determine the role of intellectual capital on performance of knowledge-based organizations based on the role and position of organizational innovation.

 The required data were collected through the distribution of a researcher-made questionnaire with 94% reliability among the managers and researchers of a defense-based knowledge organization. The present study is an applied research in terms of purpose and also in terms of descriptive-correlational research in terms of its method.

 The results of this study show that the dimensions of intellectual capital, including human capital and relational capital, both directly and indirectly affect the performance of the organization through the mediating role of innovation variable.

 It is suggested that in the field of human capital, more emphasis is placed on the field of knowledge and creativity in order to strengthen the amount of human capital and, consequently, innovation and organizational performance. On the other hand, processes and guidelines in the field of structural capital need to be strengthened to speed up the process. Also, proper team building and utilizing the intellectual chain and knowledge network in performing the work of the organization strengthens the capital, which can increase customer trust and the level of organizational performance.

In order to evaluate the dietary effects of housefly larvae (Musca domestica) as an alternative to Perinereis nuntia, on fecundity rate and larval stages development of Pacific white leg shrimp Litopenaeus vannamei, 30 pairs of L. vannamei shrimp were stocked in 3 fiberglass tanks of 5 tones containing filtered seawater under identical conditions. The brooders were fed with 3 diets including conventional diets of hatchery (P. nuntia, squid, oysters and food pellets), along with 5% of housefly larvae as a supplement (Diet A), conventional diets of hatchery along with 10% of housefly larvae as an alternative to P. nuntia (Diet B) and conventional diets of hatchery as a control (Diet C). The experiment results showed that diet A presented significant differences in promoting fecundity rates of shrimp broodstocks with the other treatments (p<0.05). The number of hatching eggs (hatching) in the treatments did not show any significant difference (p>0.05). The larval development stages of hatched eggs produced with different treatments showed that a greater percentage of larvae from broodstocks fed with diet A have developed faster to the next stage than the other two treatments, which has shown a significant difference (p<0.05), especially in post-larvae stages. However, the use of housefly larvae diet as a supplement to conventional diets of hatchery can increase the fecundity rates of shrimp broodstocks and result in faster larval development; but as an alternative to the polychaete worm (P. nuntia) in conventional diets of the hatchery, have no effect on shrimp broodstock hatcheries.
