Moshta fishing: A link between fish and fisheries and art

Fish and fisheries have long been subject of art works of ancient Persians, Egyptians and Chinese. Art has a variety of dimensions and perspectives associated with nature/environment including marine or freshwater bodies. Following the idea of linking art, fish and fisheries and the marine environment, in this study, we used local set-net fishing known as Moshta as a traditional fishing gear at the coastal area of Bandar Abbas, Iran to present emotional state and concept of repeatability. The Moshta fishing (i) repeats almost every day, (ii) stimulates emotions, (iii) brings deaths to fishes, (iv) supplies food to peoples and birds, and (v) contributes to the economy of local families. Hence, there is always a reproducibility creation in this man-made fishing gear. This process in a worthy way to bring lights to the creation of different links between fish and fisheries from one hand and art in the other hand

ANFIS to Quantify Maintenance Cost of IT Services in Telecommunication Company

The maintenance cost predication of information technology (IT) regarding their important role and well-time availability in organization is valuable for IT managers. Therefore their decision originated from the predication might be great effect on organizational budgeting, planning, and strategy management. In this regard, having enough knowledge of IT system behavior and their cost forecasting may help IT managers to develop their organization. In this chapter, adaptive neuro-fuzzy inference system (ANFIS) with capability of modeling and predication is introduced, respectively, for quantifying information technology services and their maintenance cost in one of the telecommunication companies in Iran. Because of easy accessibility in finding parameters and also prevention from the complexity of information resulting from some available services in case study organization, automation services are selected by author as kind of user-involved and widely used in finding and studying on the variable data for implementation of the model

The Effect of Organizational Commitment and E-training on E-tourism Job Performance

E-tourism combines e-commerce and Information Technology (IT) in the tourism industry. It can be defined as the investigation, strategy, application and implementation of e-commerce solutions and IT in the travel, leisure, and tourism industry. Training is required to update the skills and knowledge of employees. This learning is mandatory for performance enhancement of job-related tasks. Training and development also strives to increase organisational commitment, which can be defined as an effective connection with the organisation that encourages the employee to work productively as well as to continue to work with the organisation. Organisational commitment can be characterised by the willingness of employees to contribute to the objectives of the organisation. Previous works in the literature have investigated e-training and development and its correlation with e-tourism performance. However, the impact of organisational commitment on the relationship between e-training and development and e-tourism performance, particularly in a virtual team setting, is not well understood. Therefore, this paper investigates the mediatory role of organisational commitment on e-training and IT project performance for virtual teams working in the e-tourism field. The primary objective of this paper is to prove that improvement in e-training and development and organisational commitment of e-tourism virtual teams will also improve the job performance of the virtual teams. This work is justified from the needs of current organisations that are embracing a more virtual working environment, with the aim of catering to detached workforces—internally and externally—that communicate through IT and thus further improve organisational performance. The results help determine whether or not e-training and development helps employee participation in training programs and their perceptions towards it. The findings also prove that organisational commitment is a crucial factor affecting the productivity and efficiency of employees in the workplace

Septum Perforation in a Patient with Asymptomatic Systemic Lupus Erythematosus

Background: Systemic lupus erythematosus (SLE) is an autoimmune disease in which organs and cells are damaged by autoantibodies and immune complexes. This disease often affects the body organs, one of which is the vascular system that manifests itself as vasculitis. Rarely, this vasculitis can cause perforation and epistaxis in the nasal septum. Most people who present this manifestation in lupus are people who have a known lupus case and develop septal perforation over time. Case Presentation: In this article, a patient with epistaxis and septal perforation was referred and, finally, she was diagnosed with lupus. Conclusion: This study shows that other than granulomatous and eosinophilic angiitis (Wegner & Churg-Strauss), systemic lupus erythematous should be in mind in diagnosis of septal perforation

Preparation of Naringenin-Load Polyethyleneglycol(PEG)/Polycaprolactone (PCL) Electrospun Nnanofibers for Eevaluating the In-Vivo Wound Healing of Naringe

The skin is one of the most important defenses against pathogens. It can also be a penetrate way by wounds, damages and diseases. Some compounds like polycaprolactone fibers, phenolic plant compounds and naringenin are considered in wound treatment due to their stimulating collagen production, less side effects and high efficiency, respectively. Combining nanofibers and phenolic compounds is noticed to accelerating wound treatment. Materials and methods Synthesizing nanofibers of polycaprolactone and polyethylene glycol 3:1 in ratio using electrospinning and confirming by scanning electron microscope and FTIR test was done to perform this project. Then the rate of releasing of 3.125% naringenin of synthesized nanofibers were investigated by UV-visable. The animal test was done by creating wound on the Wistar breed rat and measuring the wound area during the test for 14 days and analyzing the datas use of imageJ and spss softwares. The wound tissue was removed for the tissue studies on the 15th day. Test results showed that the increase in naringenin concentration along nanofibers reduces the releasing rate. Likewise, in animal studies, outcomes showed that wound treatment in the nanofibers group on 1st, 4th, 7th days has no noticeable differences compared with the control group, on 10th and 14th days the treatment was decreased significantly and on the 1st day there was no significant differences compared with the nanofibers group containing naringenin. On the 4th , 7th , 10th , and 14th days there was no significant difference in nanofibers group containing naringenin compared with control group, but on 1st ,7th ,10th ,and 14th days a noticeable increase in healing was observed

Optimal control of system governed by nonlinear volterra integral and fractional derivative equations

AbstractThis work presents a novel formulation for the numerical solution of optimal control problems related to nonlinear Volterra fractional integral equations systems. A spectral approach is implemented based on the new polynomials known as Chelyshkov polynomials. First, the properties of these polynomials are studied to solve the aforementioned problems. The operational matrices and the Galerkin method are used to discretize the continuous optimal control problems. Thereafter, some necessary conditions are defined according to which the optimal solutions of discrete problems converge to the optimal solution of the continuous ones. The applicability of the proposed approach has been illustrated through several examples. In addition, a comparison is made with other methods for showing the accuracy of the proposed one, resulting also in an improved efficiency

Evaluation of the Effect of Barberry Root (Berberis Vulgaris) on the Prevention of Metabolic Syndrome Caused by Atypical Antipsychotic Drugs in Patients with Schizophrenia: A Three-Blind Placebo-Controlled Clinical Trial

Objective: Metabolic syndrome is a potential side effect of atypical antipsychotics which are the current standard treatment for schizophrenia. Therefore, we aimed to examine the effect of barberry root (Berberis vulgaris) on the prevention of metabolic syndrome caused by atypical antipsychotic drugs in patients with schizophrenia. Method: Our research was a three-blind randomized clinical trial. The participants included all patients who were diagnosed with schizophrenia through the SCID-5 questionnaire and based on the DSM-5-TR criteria by two psychiatric experts. These patients were randomly divided into intervention and placebo groups. During a three-month treatment period, the intervention group received three 500 mg capsules of barberry root extract daily, whereas the placebo group received the same capsules containing 500 mg of starch powder. Metabolic syndrome variables including fasting blood glucose, serum lipids (triglyceride and cholesterol), blood pressure, weight and waist circumference were measured before and after the treatment as outcome measure. Chi-square and t-tests were used for data analysis using SPSS-22 software. Results: At the beginning of the study, there was no significant difference between the intervention group (n = 41) and the placebo group (n = 47) in terms of demographic factors, and pre-treatment assessments including weight, waist size, fasting blood HDL, fasting blood triglycerides and systolic and diastolic blood pressure and fasting blood glucose (P > 0.05). Within group analysis showed that some metabolic factors significantly increased in both groups after the treatment (P < 0.05). Indeed, in both groups, metabolic syndrome measures worsened after the three-month treatment period. The parameters of weight and waist size were significantly higher in the intervention group than the placebo group after treatment (P < 0.05). Conclusion: Barberry root extract was not able to control the Effects of antipsychotic drugs on metabolic syndrome in schizophrenia
