  COVID-19 has shown a high rate of spread and a high death rate. This disease puts the mental health of people in a different social class at risk. The present study was a comparison of meta-worry, rumination and cognitive distortions in COVID-19 pations recovered and normal individuals. Causal-comparative model was hired in the present study. The population of this study included all COVID-19 patients recovered as well as normal people referring to Tonekabon health centers in the period of July and August 2021, of which 120 people were selected according to conveniense sampling. The research instruments were meta-worry Questionnaire (MWQ), the ruminative response scale (RRS) and cognitive distortions scale (CDS). To analyze the collected data, a MANOVA was run using SPSS-24 software. Data analysis reveal that there were differences between meta-worry, mental rumination and cognitive distortions in the two groups of people who recovered from COVID-19 and normal people; those who recovered from COVID-19 indicated more meta-worry, mental rumination and cognitive distortions than normal people. It can be said that based on the results of this research indicating the higher level of rumination, cognitive distortion and meta-worry in people recovered from COVID-19, it is possible to reduce these variables by teaching adaptive strategies to recovered people to deal with meta- worry, rumination and cognitive distortion.

The effects of motor imagery and physical practice on motor learning in individuals with ADHD received very little attention. Therefore, in the present study, we aimed to examine the effects of motor imagery and physical practice on motor performance and learning dart-throwing in adolescents with ADHD. The current research was based on a causal-comparative approach. The participants included 60 adolescents with ADHD (with the age range of 12 to 17 years) randomly and equally assigned into four groups: 1) motor imagery, 2) physical practice, 3) combination of motor imagery and physical practice, and 4) control. The motor task involved dart-throwing, in which the accurate throw score was measured as the dependent variable. The participants performed the pre-test (ten throws) and the retention test (ten throws). ANOVA was run to analyze the throwing accuracy. Results showed that all groups had similar throwing scores in the pretest, however, in the retention test, the results indicated that combination group had significantly better throwing scores than all other groups (in all groups, P=0.000). In addition, physical practice group had significantly better throwing scores than motor imagery and control groups (both P=0.000). Finally, motor imagery group had significantly better throwing scores than control group (P=0.000). Individuals with ADHD benefit from motor imagery, indicating that they have the necessary mechanisms to learn new skills through motor imagery. Moreover, a combination of motor imagery and physical practice would be a better strategy for learning new motor skills.

Throughout history, Iran has always been exposed to many natural and unnatural crises due to its geographical, economic, cultural, natural, and political characteristics, and especially its location in the strategic region of the Middle East. This study aims to investigate the position and role of the logistics capacities of the Islamic Republic of Iran Navy (IRI Navy henceforth) in encountering the natural disaster crisis. The entire participants included 120 senior officers of the Deputy of Readiness and Support, the heads of readiness and support of the affiliated regions and bases, and the middle managers of the headquarters and ranks of the Readiness and Support Command of Najaf among whom 92 were selected randomly based on Krejcie and Morgan’s (19700 table. Data were collected quantitatively using researcher-made disaster management questionnaires and IRI Navy preparedness capacities. Then, the validity of the questionnaire was assessed through confirmatory factor analysis and its reliability was assessed by Cronbach’s alpha. To test the hypotheses and the accuracy of the conceptual model of the research, the structural equation modeling method using the partial least squares (PLS) method was used. Findings indicated the significance of the IRI Navy's preparedness hypotheses on managing and reducing the damage caused by the natural disaster crisis. The results showed that the component of responsibility had the highest rank and importance and the components of timeliness, information, and technology, coordination, mobile systems, efficiency, and preparedness were among the next priorities of logistics capacity in case of encountering a natural disaster crisis, respectively.

As one of the most popular means of trade in the world, shipping by sea has always been subject to maritime hazards. Thus, the implicit commitment of a ship lease contract is that the transport operator provides a seaworthy ship. There is, however, no specific definition of the legal nature of this obligation in most conventions or international laws, and it is only in this regard that the statement of seaworthiness is cited as an implied obligation. Having been written in the descriptive-analytical method, this study attempts to explain the legal nature of this obligation, its position among absolutes or relatives, primaries or subsidiaries, implicit fundamentals or customs, its compliance with the conditions of article 234, the burden of proving seaworthiness, and the lack of performance guarantees caused by its absence. According to the results of the study, a transport operator is under a relative obligation to provide a seaworthy vessel. The existence of this obligation can be mentioned both as a main condition and a secondary condition, and if there is no specification in the contract, it is referred to as a customary implied obligation. Additionally, the condition of seaworthiness would be close to the verb condition in accordance with Article 234 of the Civil Code of Iran. For a claimant (the owner of the goods) to prove a lack of seaworthiness, they only need to provide evidence that the loss has occurred. For the sea transport operator to be relieved of responsibility, s/he must prove that s/he took the necessary precautions at the start of the voyage. The owner, otherwise, is responsible for compensating the victim for the damages caused by the violation of unseaworthiness by restoring the previous situation by providing the property and if an excuse is provided, by supplying a substitute.

The seabed chamber of the International Tribunal for the Law of the Sea is an authority for dispute settlement in seabed area cases. This chamber, in nature, is a specific judiciary for dispute resolution of this marine area in the tribunal. First, the governments must settle their disputes based on one of the peaceful resolution methods, and then should refer to the tribunal in case of agreement. Compared to the International Court of Justice in referring to dispute settlement, the most important feature of the tribunal and its chamber is the creation of a specific chamber and dispute settlement through arbitration and the presence of a special judge for dispute parties. Moreover, the seabed chamber can issue an advisory opinion, if required. Therefore, the jurisdiction of the chamber depends on two kinds of optional and compulsory jurisdictions of the tribunal, so that contractors and their guaranteeing states have joint liability for international seabed authority. It should be noted that states are responsible for an action and omission of the act causing harm in the seabed and under the seabed only in case of failure to apply their regulatory advice for contractors. The first and most important compensation for harm to the seabed is prevention from more hazards against seabed and under the seabed. Furthermore, immediate notification to coastal authorities and states, postliminium (restoration of the status formerly possessed), and complete compensation are forms of respective actions.
