The basic issue in the current research is the selection and prioritization of portfolio projects of modern technologies and defense medicine in an industrial research organization based on the portfolio management standard. Through library studies and interviews with experts, the criteria for selecting and prioritizing these projects were calculated in the form of five main criteria (including technical, resource, strategic, socio-political, and biomedical and defensive) and 22 sub-criteria. The statistical population includes managers and experts of biotechnology projects of an industrial research organization and two Imam Hossein University (AS) and Baqiyatullah University of Medical Sciences (AS) and their affiliated research centers. With a targeted sampling strategy from among available experts and experts, people who are more familiar with the field of modern technologies and defense medicine, missions and research centers related to this specialized field, and also have knowledge about things related to project portfolio management, for 55 people were chosen to answer the questionnaire, and 47 cases were received after distributing the questionnaire. To check the validity of the research, the Lawshe formula was used and Cronbach's alpha coefficient was used to check the reliability. To investigate the hypothesis tests, one-sample t-test was used, and to determine the weight of the main criteria and sub-criteria, the hierarchical analysis method was used. In the end, the Vicor method was used to rank and select the projects, and the biology system project won the first rank among the six new technologies and defense medicine projects.

Anterior cruciate ligament (ACL) injury is one of the most common and serious injuries of the knee joint, which accounts for 80% of all knee ligament surgeries. Studies have shown that a significant percentage of this injury (70%) occurs in a non-contact form, usually during activities like deceleration, landing, or side cutting. Studies have shown that focus instructions could improve and promote performance. This study aimed to investigate the acute effect of focus instructions on biomechanical indexes associated with ACL injury prevention.

In this research, 24 young football players from the two clubs of the Tehran Premier League, Tehran City, Iran, were randomly divided into two groups: external focus attention (n=12) and internal focus attention (n=12). First, the dynamic postural stability index (DPSI), the peak of vertical, anteroposterior, and mediolateral GRF components, and the rate of loading during the jump-landing movement from a box with 30 cm height were calculated using a force plate with a sampling frequency of 1000 Hz. Then, the internal and external focus instructions were taught to the participants, and the two groups performed a posttest to examine the changes. Statistical methods of repeated measures analysis of variance and paired t test were used to evaluate the changes.

The results showed significant changes in the vertical component and rate of loading variables in both groups of internal and external focus attention (P≤0.05). However, no significant difference was observed between the two groups in the DPSI, anteroposterior and mediolateral GRF.

The results of this study showed that acute instructions of both internal and external focus attention can improve landing mechanics and landing-related kinetic variables. It seems that the external focus instructions have increased the motor control of the limb, leading to a further reduction of vertical GRF and the load applied to the lower limb compared to the instructions of internal focus, thus reducing the risk of ACL injury.

Mulla Sadra is the first thinker who openly talked about three sources - revelation, intuition and proof - to reach a comprehensive reality and methodically used them in his philosophy. One of the interpretations of this theory is the "interdisciplinary approach" or "Talfigh". "Talfigh" here means intelligent, logical and coherent use of the three mentioned sources. In this research, we have criticised the mentioned interpretation to clarify its quality and identify whether it is the answer to the issues that Sadra was looking for or no? As a result, we found that this interpretation can be modified and completed in five axes. First, not stating how this approach works, second, not using Talfigh in all transcendental philosophy, third, not stating the position of these sources, fourth, the monopoly of synthesis in the philosophical method, and lastly, this interpretation is not responsible for solving the problems that Mulla Sadra sought to solve

Third party intervention in international justice has become increasingly important in contemporary international law. Recent developments in the case of Ukraine against Russia in the International Court of Justice may force the Court to pay attention to an important point related to the procedure of the Court regarding the entry of a third country and the manner of proceeding based on Article 63 of the Statute of the Court. The present study is written in a descriptive and analytical method and based on the study of the case of Ukraine to analyse the right of entry of the third state based on Articles 62 and 63 of the Statute and Articles 81 to 86 of the International Court of Justice's Rules of Procedure for violating universal obligations. It is argued that the court, taking into account the legal rules, the judicial procedure, the principles of humanity and the public conscience on which it acts, has adopted a precise interpretation regarding the entry of the third state. The results show that in cases where the rights between the international community of countries as a common whole are involved, if the existence of comprehensive obligations is proven, the Court should adopt a broad interpretation that favors the legal entity of the entry of the third country.

The overall aim of this study was to investigate the effect of eight weeks of upper quadrilateral training on chronic middle-age men's headache.

The research method was semi-experimental and research design was pre-test and post-test. The statistical population of the study included all middle-aged men with tension headache referring to health centers affiliated to Tehran University of Medical Sciences. The sample consisted of 6 subjects who were selected from among those referring to health centers. The criteria for entry into the study included: confirmation of the criteria for chronic tension headache by a neurologist and having a range of 40- 55 years. Information about the severity and frequency of headache and drug consumption in both groups before and after the exercise were assessed by a self-assessment questionnaire. Subjects' sleep quality was assessed in two stages: pre-test and post-test using the Pentecostal sleep quality questionnaire. Became

T-test results (at the level of error of α = 0.05) showed that eight weeks of upper quadrilateral training on the severity and duration of chronic tension headache and also the reduction in the dose of analgesics and ultimately the sleep quality of people with tension-type headache Chronic effects had a positive effect (p <0.001).

The results of the study suggest that occupational therapists use upper quadrant physical exercises to improve the patient's cold pain.

Fatigue of the quadriceps muscle causes pain and decreased knee proprioception. The aim of research was the effect of two PNF stretching programs and lower limb strengthening on pain and knee proprioceptive of the knee joint before and after local fatigue of the quadriceps muscle in male athlete with patellofemoral pain.

This research was semi-experimental and pre & post-test. The statistical population included men aged 20-30 with patella pain in Tehran. 24 people were placed in two groups of PNF stretching exercises (12 people) and strengthening (12 people) in a targeted and random selection. All subjects signed a personal consent form before participating in the study. Each group did their exercises for eight weeks and three 60-minute sessions each week. Before & after the exercises (before and after the test), knee pain and proprioceptive sensation were measured using visual pain measurement (VAS) and biodex isokinetic (model IV Pro made USA), respectively. Data were analysis significant (P<05/0) using the combined repeated measure.

the comparison of the first and third tests (before fatigue) (ES=0.5, p<0.05 and        F (1,22) =4.417) . The comparison of the second & fourth tests after fatigue(ES=0.8, p<0.05 and F (1,22) =148.4), there was a significant difference (ES=0.4, p<0.002 and F (1,22) =52.14). Pain reduction after training was 29% in the stretching group 18% in the strengthening group. The net effect of training on depth sensation improvement was significant (ES=0.6, p<0.005 and F (1,22) =2.404). Regarding the comparison of the first & third test (before fatigue) (ES=0.6, p<0.001 and F (1,22) =108.2). The comparison of the second & fourth test (after fatigue), there was a significant difference (ES=0.5, p<0.002 and F (1,22) =51.1). The improvement in proprioception after training was 15% in the stretching and 11% in the strengthening group. The exercises in the PNF stretching group were more effective on both variables in the post-test and after the training period.

Both exercise programs have been concluded for pain factor and proprioception, but the effect of PNF training to reduce pain and improve proprioception of patients was the amount of consumption.

Muscle injuries are one of the most common reasons for missed playing time in the football, and the hamstring muscle is one of the most common injures. The role of this muscle in supporting ligaments is also important. In spite of different structural and kinematic features of the hamstring in men and women, a few studies have investigated these differences; therefore, The purpose of this study was to determine the effect of six weeks of Nordic hamstring training on the isokinetic strength of the hamstring muscle of elite female and male soccer players.

24 soccer players (12 female and 12 male) from youth first division league in Tehran province participated in this study. The isokinetic strength of the hamstrings and quadriceps muscles at various angular velocities was measured. After the pre-test, the subjects performed six weeks of Nordic exercise as part of their warm-up.

Performing Nordic hamstring exercises caused a significant difference in the isokinetic strength of the hamstring muscle after the test and at angular speeds of 60, 180 and 300 degrees per second, as well as a significant difference in the ratio of the isokinetic strength of the hamstrings to the quadriceps at a speed of 60 degrees per second between of elite female and male soccer players (P=0.001).

It is concluded that Nordic hamstring exercise improve isokinetic strength of the hamstring muscles and reducing the risk of injury in the knee joint.

The need for change in the era of complexity is one of the basic needs of organizations. However, several studies indicate the failure of many organizations to successfully go through the change journey. Organizations not being ready to start the change journey is considered one of the reasons for this failure. Based on this, the existence of a tool that can evaluate the state of readiness for change and help managers to go through the change journey better is demanded by many organizations and managers. In this article, a framework for measuring the level of readiness for change is presented and based on it, the desired variable is evaluated in a military organization (Imam Hussein University (AS)) and the proposed model is also developed using the collected data. has been examined and fitted. The result of the research indicates that all the coefficients of the model have reached statistical significance with a confidence level of more than 99%, and the overall research model consisting of dimensions of behavioral factors, contextual factors, structural factors, and individual and group dynamic factors has been approved.

The aim of the present study was to compare the electromyographic activity of quadriceps muscles and hamstrings of male and female professional soccer players in a single-leg landing movement.The samples were 38 professional football players in Tehran province (19 women and 19 men). Electromyographic activity of quadriceps muscles and hamstrings were measured during the single-leg landing test. Independent t-test was used to compare muscle activity and timing of quadriceps and hamstrings in men and women.The results of this study revealed that there was a significant difference between men and women professional footballers between feedforward activity of rectus femoris muscles (P = 0.05),Vastus medialis (P = 0.05), Vastus lateralis (P = 0.05), feedback activity of Semitendinosus muscles (P = 0.05) and Biceps femoris(P = 0.05) . The induction of Semitendinosus muscles of women compared to men was reported with delay (p = 0.006). Also, early activation of Vastus lateralis muscles in women was observed compared to men (p = 0.001).As shown in this study, more feedforward activity of female quadriceps muscles, delayed onset of Semitendinosus activity and early activation of Vastus-lateralis muscles in women than men, in the task of landing on one leg, make women more prone to ACL injury. it can be stated that one of the causes of ACL injury in women is the presence of defects in their neuro-muscular control system. As a result, strengthening and improving the nervous system of the hamstring muscles, especially in women, is recommended to prevent ACL ligament injury.

Strengthening hip muscles considered as one of methods in prevention and rehabilitation injuries and musculoskeletal disorders. role of abdominal muscles in maintaining the stability of core especially prevention of unwanted movements in spine has been proven. exercise can strengthen these two areas is Plank. The aim of study was to compare hip abductor and abdominal muscles in different Plank exercises positions. according to selection criteria, 18 male aged 18 to 23 years were in study. The amount activity in terms of maximum voluntary isometric contraction and onset time activation of gluteus medius , Tensor fascia lata, internal oblique and external oblique in 3 types plank exercises; side plank with hip abduction, with hip abduction and flexed knee, with trunk abduction was measured by EMG. data obtained from study were analyzed based on Repeated Measure ANOVA test. results showed there was significant difference in activity of Gluteus medius, Tensor fascia lata and external oblique in 3 types Plank exercises (P≤0.05). maximum activation of gluteus medius, Tensor fascia lata and internal oblique was seen in first exercise but maximum activation of External oblique was seen in second exercise. Significance was not observed only in internal oblique muscle (P≥0.05). results did not show significant difference in onset time of any of muscles among exercises (P≥0.05). it can concluded Side Plank exercises used to strengthen hip muscles and also effective use of core muscles relation to each other. most effective condition for activation of abductor and internal oblique is side plank with hip abduction.

In recent years, our country has been subject to the most severe economic sanctions, and the oil industry has not been immune from these sanctions, so that it is difficult to purchase or renovate equipment in the boycott. The reconstruction and repair process is one of the best alternatives. Also, the uncertainty of the time of the implementation of activities has increased the understanding of project owners from the scheduling of activities and opened up a broader view of the project and the upcoming activities. In this research, the design of an integrated schedule of activities and supply chain for reconstruction projects of drilling rigs under conditions of uncertainty of the time of implementation of activities is presented and the costs of the contractor and suppliers have been observed, and the uncertain scheduling of activities and planning of orders have been made in such a way that the total cost The whole chain is minimized. Given the number of variables and model constraints, the problem is NP-hard. Therefore, to solve such problems, the meta-heuristic methods are used, which produces near optimal solutions in a reasonable time than the exact methods. By comparing the results of exact resolution and meta-heuristic-algorithms, it was found that with increasing problem dimensions, the exact solution time is exponentially exponentially, but the solving time by the meta-heuristic-algorithm has a steady trend that indicates the efficiency and effectiveness of the proposed algorithms.

The importance and position of common oil and gas resources in the global economy and their role in earning huge incomes and more importantly, the stabilization of the political position for the surrounding countries has caused the legal regime governing their exploitation to be of great importance in law. be international The close connection of common oil and gas resources with the legal phenomenon of border, jurisdiction and sovereignty of governments are among the most important and complex concepts of international law, which has made these resources more important in international relations between the beneficiary governments. In order to achieve a proper understanding and complete knowledge of the concept of common oil and gas resources and to master the legal regime governing them, first of all, the different dimensions and methods governing this economic and international phenomenon should be explored.

The current research method is based on descriptive-analytical method using library resources and research and study of books, articles, documents, statutes, conventions and international treaties.

We found that one of the most important and important economic, political and noteworthy issues in the last century in the national and international arena is the issue of common oil and gas resources and the rules and regulations governing the exploitation of these huge energy resources. Is. The issue of joint oil and gas fields has long been of interest to governments and large international oil companies, and without a doubt, it is necessary to define the issue of exploitation of these huge energy resources, specifically oil and gas, based on legal rules and regulations. be interpreted so that there is a logical and reliable framework for the stakeholders and actors of this important business area. With this description, international law as a regulator in various aspects, especially preventing disputes and threats to regional and international peace and security in legal dimensions, responds to the existing needs in the form of branches under the title of international oil and gas law. It appears to bring various issues related to the exploitation of joint oil and gas fields under the control of its laws and regulations.

The Persian Gulf, this advancement of water in the land, which has caused the separation of the Hejaz land from the Iranian plateau and the creation of geopolitics in the Middle East region, has a strategic and very important position in the field of international law. Considering the economic benefits of this waterway, especially in the field of oil and gas in the continental plateau region and the extensive exchange of goods in the Persian Gulf, the study and investigation of the legal system governing this international waterway is very sensitive and important.

The current research was conducted using analytical and descriptive methods.

In this research, by examining the legal system of the Persian Gulf and the agreements concluded regarding the delimitation of the boundaries between the coastal countries, the principles considered in the 1982 Convention on the Law of the Sea and the 1958 Convention on the Continental Shelf and the effect of the delimitation agreements between Iran And the countries of the Persian Gulf are taken into consideration in the formulation of the legal system of the Persian Gulf. According to the results obtained, in delimiting the limits of this strategic waterway, following the international laws and regulations, Iran has followed the usual and general practice in the Persian Gulf, which is to favor the fair line and the equal line of the parties.

Changing the knee flexion angle and using unstable devices are some ways to change the activity of the hip and trunk extensors in supine bridge exercise. The present study intends to compare the effect of different knee flexion angles in bridge exercise at the unstable surface on the activation of selected muscles of young male soccer players.

Eighteen young players performed one-session bridge exercises on a Bosu ball on full-extension (0°), 45°, and 90° of knee flexion, and electromyography was used to assess the amount and the onset of activity in selected hip muscles.

The results showed a significant difference in the electrical activity of Semitendinosus, Biceps Femoris, Gluteus Maximus, and Gluteus Medius at different knee angles (P=0.001). Furthermore, Even the results showed a significant difference in the onset of Gluteus Medius muscle activity at different knee angles (P=0.005), but the difference was not significant in the onset of Semitendinosus muscles (P=0.52), Biceps Femoris (P=0.12) and Gluteus Maximus (P=0.40) at different knee angles.

For strengthening the Hamstrings, bridge exercise with less knee flexion angles and for reinforcing the Gluteal muscles, bridge exercise with more knee flexion angles showed more effectiveness. Additionally, results have shown that performing bridge exercises on Bosu Ball with 45° of knee flexion can activate the Gluteus Medius muscle faster. Therefore, based on the findings of this study, this exercise on different angles of the knee joint can be used for specific aims and by considering the individual needs.

The purpose of this research is to present a two-objective nonlinear integer programming model for optimization of a general commodities supply chain, minimizing the purchase costs and delivery delays and maximizing the resilience with uncertain constraints and parameters of the objective functions. To solve the model, the weights of relevant metrics and sub-criteria for producers are obtained through multi-criteria decision making. These metrics are used as the input data to the proposed mathematical model. Since this is classified as a hybrid optimization problem in the NP-hard problem family, NSGA-II and MOPSO multi-objective evolutionary algorithms are used to solve the proposed model. Comparing the results of the algorithm is done with the help of comparative indices. In this study, the probability constraint programming is used for the fuzzy to deterministic conversion of models. This method fits the LAM and UAM estimation models appropriately to the pessimistic-optimistic changes due to the differences in the decision makers' attitudes. Results of comparing these algorithms indicate that the genetic algorithm performs better in the optimistic view, whilst the MOPSO algorithm performs better in the pessimistic case. The results of NSGA-II and MOPSO algorithm for the designed sample problem show that NSGA-II algorithm performs better than MOPSO algorithm in different criteria. For instance, better performance regarding the solution time and the criterion of the distance from the ideal point, is observed in all problems.

Recently the reactive neuromuscular training (RNT) has received increasing attention due to its function in decreasing the sport injuries. These exercises help athletes to quickly correct their faulty movement patterns. The aim of this study was to investigate the effect of eight weeks of reactive neuromuscular training on landing kinematics in Female Basketball Players. Thirty three players from the three teams of the Tehran Female's Basketball Premier League participated in this study. The teams were randomly divided into three groups: experimental 1 (n=11), experimental 2 (n=11) and control group (n=11). Experimental group 1 performed prevent injury and enhance performance (PEP) exercises for eight weeks and experimental group 2 performed PEP exercises with RNT instead of regular warming up. The control group performed their usual exercises. The kinematics of the trunk and lower extremity joints during landing were evaluated by pre-test and post-test. Three-dimensional lower-extremity kinematics was measured during drop jump with a single leg landing. Data were analyzed by 2-way repeated measures analysis of variance. The results showed that eight weeks of reactive neuromuscular training had a significant effect on hip flexion angle at landing (F(2,27)=3.40, P=0.04, ηp2=0.20). But there was no significant effect on knee valgus, knee flexion, ankle dorsiflexion, and trunk flexion at the moment of landing following RNT training. The presented results indicated that the injury prevention program using reactive neuromuscular exercises could well modify the athletes' movement patterns toward a lower risk of anterior cruciate ligament injury.

 The use of the seas and in a narrower sense of the oceans has always been the concern of governments in the economic, scientific, military and strategic fields throughout history, and this importance has been increased in the present era. The law of the seas is a part of the rules of customary law that have been gradually compiled later. The third United Nations Conference on the Law of the Sea, which successfully adopted the Convention on the Law of the Sea in 1982, has a special importance in the development of the law of the sea. The sources of the law of the seas include customary international treaties, general principles of law, rules governing unilateral legal actions, doctrine, judicial procedure and international arbitration. One of the most important sources of the law of sea waters is the procedures of the International Court of Justice, the International Court of Law of the Sea, because while citing the treaties related to the seas and their progressive change, they bring to the fore the creation of the customary rules of the seas as well as the expression of the existing customary rules of the seas. 

 The current research, which is written with an analytical-descriptive method, seeks to answer these important questions: how do the International Court of Justice and the International Court of Law of the Sea get help in solving international disputes from the law of the sea? And to what extent can the law of the seas be a solution to international disputes?

 The purpose of the current research, which is focused on the impact of the law of the sea on the fundamental structure of international dispute settlement rituals and on the extent of these laws in issuing the opinions of the International Court of Justice and the International Court of Law of the Sea, expresses this finding. May the law of the seas not have much effect on the decisions issued by the International Court of Justice. Another thing is that due to the shortcomings and gaps in this field, it cannot be the answer to solving international disputes. It seems that the law of the seas can be a guide in issuing the opinions of international organizations through the provision of solutions and legal rules accepted by countries.

 The present study examines one of the issues of the international law of the seas, namely the government's sovereignty in the territorial sea. This issue has always been one of the topics raised in the international law of the sea. In fact, the main motivation for writing this research was to investigate and analyze the aforementioned cases in the international arena and the legal status of Iran's coastal state on its territorial waters. In turn, this research has tried to avoid any one-sided interpretation of the governments in the field of issues related to the government's sovereignty in the territorial sea, to clearly examine this issue and related issues, for this purpose, the existing rules have been tried They should be detailed and, if necessary, accompanied by a historical review, and among the ambiguous rules, they should be clarified as much as possible. In cases where there are no rules, suitable suggestions have been made.

 The current research is trying to answer this question with a descriptive and analytical method, what are the legal foundations and competencies of the Iranian government compared to the conventions of 1958 and 1982?

 The results of this research show that Iran's maritime law system is based on three approaches compared to the 1958 and 1982 conventions: a) Iran's maritime law system has taken initiatives. b) Iran's legal system has approved the legal principles and rules contained in the Convention on the Law of the Sea. c) Iran's legal system in the third approach, contrary to the 1982 Convention on the Law of the Sea, has remained silent in explaining legal issues.

 There are rights whose purpose is to provide protection for people when they are under interrogation, the principle of innocence, the prohibition of torture and cruel, inhuman and degrading treatment, the prohibition of forcing people to confess or testify against themselves, the right to remain silent. , the right of access to the translator is one of those rights that will be discussed in this chapter with regard to international law. Several rights whose purpose is to guarantee the safety of the accused during the interrogation, including the presumption of innocence and the right to an interpreter, the preparation of interrogation minutes, the prohibition of any torture or cruel, inhuman and degrading treatment, the prohibition of forcing people to confess or testify against themselves, the right Silence and the right to access a lawyer.

 The research with an inferential method based on the analysis of events and police procedures in countries seeks to answer these questions: The main challenges raised at this stage are what rights does the accused have at this stage? Has his right to defense and silence been recognized at this stage? Are the judicial officers obliged to announce the right of silence to the accused? Asking such questions and answering them, as soon as the accused enters the cycle of criminal justice, because the progress of human rights and its connection with the understanding of human dignity and high value in society, respect and protection of his (accused) basic rights and freedoms ) and efforts to create and support peace and security in the society, strengthen and promote high human values ​​and achieve justice, become important.

 From the results and findings of the present research, it can be concluded that the police in most countries do not have a satisfactory record of compliance with international human rights standards in the police investigation process according to the available evidence. Therefore, this article aims to, firstly, the global standards of human rights in the process of police performance in the field of crime prevention and police investigation, according to international human rights documents and standards, with an emphasis on the international judicial practice of judicial authorities, especially the European Court of Human Rights, which in this regard It has valuable and path-breaking achievements, and secondly, the effects and consequences of violating these principles and standards will be examined according to the regime of international responsibility of governments as well as preventive mechanisms.

Functional Movement Screen Test is one of the tests used to identify asymmetries and limitations in basic and fundamental movements. For time management and fast execution of this test, some researchers have suggested reducing the number of tests. The purpose of the present study was to investigate the internal consistency and correlation between components of this test. The present study was a correlational study. In this study, movement screen test was performed on 165 male and female students aged 18 to 25 years of Shahid Beheshti University using a special FMS kit. Results The internal consistency of the test, measured by Cronbach's alpha method, was acceptable (α=0.71). The results of multivariate regression test showed that there was a low to medium correlation between the internal components of the test, but a high correlation was observed between the test components and the final FMS score. The results also showed a high correlation between the "four small movements" (Active leg raising, shoulder mobility, stability push up and rotary stability) and the total FMS score and a low correlation between the "three big movements" and the FMS score. Motor function screen test is a valid tool for evaluating motor performance. The results also show that in large communities such as students, and if there is a time limit, "four small movements" can be used instead of seven.

Organizations need effective human resource management to achieve the best results. Human resource management measures can affect the performance of the organization and create a sustainable competitive advantage and survival in the dynamic environment. High -performance work system is a coherent set of relevant human resource management measures that, while selecting and developing effective work forces to achieve the goals and purposes of the organization. The purpose of the research is to investigate the impact of high -performance work systems on individual and organizational effectiveness with mediation of the flexibility of human resources in a military organization. In this regard, based on a cross-sectional survey research in a Military organization with a sample sampling of 21 managers and experts, the selection to validate the model, the impact of high-performance work systems on individual and organizational effectiveness through the resilience of human resources flexibility Structural Equation Modeling Method. The results of the final modeling showed that the human resource flexibility variable had the highest possible effect size of 60% in the research model. Considering the significance of the whole model paths, the most effective path of the model with regard to the high value of the path coefficient, the pathway of the impact of the working system the high performance is on the flexibility of human resources with a value of 78%. Also, considering the values of the coefficient of model determination, all the measures in the power model explain 65 percent of the individual effectiveness changes and 70 percent of organizational effectiveness, while the flexibility of human resources in the role of mediator is 35 percent of the impact of high performance work systems on individual effectiveness and by 34 percent, the effect of high performance work systems on the effectiveness of the organization is moderated. If high-performance work systems can be designed and constructed correctly, it can be possible to consider the components of it, such as job design, bonus system, organizational structure, information system, people (selection, training and empowerment). A great impact on the flexibility of the organization's human resources can be created and consequently enhances the effectiveness of individual and organizational effectiveness..

Common Article 1 of the 1949 Geneva Conventions and the First Additional Protocol, open a new chapter on the concept and nature of states obligations to respect and ensure respect for humanitarian law in the occupied territories and impose binding obligations on occupying states. The present research, aims to answer the following question: the responsibility of the Israeli occupying forces to fight and prevent the spread of COVID-19 in the occupied Palestinian territories are organized and justified on what legal and intellectual foundations? Using a descriptive-analytical method, the paper provides a legal analysis of the existing facts. It is believed that despite the commitments of the occupying Israeli forces to ensure respect for international humanitarian law under Common Article 1 of the Geneva Conventions in terms of preventing and fighting COVID-19 as a vital example of the right to health and the protection of public health of the inhabitants of the occupied Palestinian territories, ensuring the actual implementation of these fundamental human rights faces serious challenges.

The aim of this study was to describe the profile of the Perceived Physical Fitness Scale among Iranian students. For this purpose, 13278 people (5153 men and 8125 women) with a mean age of 21.51 ± 5.01 in 3 age groups (under 20 years, 20-29 and over 30 years) participated in this study and completed the Perceived Physical Fitness Scale. The results showed that the overall mean of Perceived Physical Fitness in the age group of <20 years was 32.82 ± 4.89, in 20-29 years was 32.92 ± 4.84, and in the age group over 30 years was 32.88 ± 5.14 . Regardless of age, the 25, 50, and 75 percentage points were 30, 33, and 36, respectively. Therefore, according to the present results, it is possible to identify people in the perception of physical fitness and, if necessary, take solutions for those people who have a low perception of physical fitness.
