Background: Achievement of a vascular access in pediatric patients is a very difficult, time-consuming, and boring process. The present study aimed to evaluate the patency of the two vascu-lar access catheterization techniques including percutaneus IJV cannulation and saphenofemoral cutdown in terms of the functional time of catheterization and the complications of these two vas-cular access methods among the neonatal and pediatric patients. Methods: This prospective interventional case series study was conducted on 88 children admitted to the intensive care unit (ICU) and needing an intravenous cannulation. The study population was randomly (using a computerized random number table) assigned into two groups undergoing vascu-lar catheterization by saphenous vein cutdown (n=59) and percutaneus internal jugular vein cathe-terization (n=29). The two groups were compared regarding the rates of catheter blockage; vein thrombosis and infection. The data were analyzed using SPSS software.Results: The duration of catheter functionality was significantly shorter in the saphenofemoral vein cutdown group than that in the internal jugular vein catheterization group (11.4±12.2 and 14.82±11.39, respectively; P = 0.021). However, we showed no significant difference between the two groups in the prevalence rate of hematoma (p = 0.794), bleeding (p = 0.601), catheter blockage (p = 0.989), site infection (p = 0.684), sepsis (p = 0.937), vein thrombosis (P = 0.999), hemothorax (p = 0.937) and pneumothorax (p = 0.937). Conclusion: Vascular access through internal jugular vein resulted in a longer functional catheteriza-tion in ICU admitted children, compared to saphenofemoral vein cutdown, without any difference in other technical-related outcomes.

This study examines the definition of organizational knowledge in industrial and commercial companies. Knowledge in an organization is knowing the reality or situation of something, however awareness and understanding that have been obtained through experience, study, exploration and mental communication and have been recorded in various forms and the purpose of knowledge management is to identify, acquire and organize and Appropriate storage and transfer of knowledge in order to improve and change the perceptions and performance of employees at different levels of the organization at the appropriate time, which prevents the outflow of intellectual and mental assets from the organization when leaving knowledge agents. Knowledge management consists of various elements such as knowledge production, knowledge acquisition, knowledge storage and transfer and sharing. However, it can be said that knowledge transfer is the movement, distribution and dissemination of knowledge between individuals and mechanized and non-mechanized knowledge bases. In two ways, for which two types of strategies are conceivable, the strategy of person-to-document transfer and the strategy of person-to-person transfer. The role of human resources training and development professionals in the management and knowledge transfer process is critical. These maps can be created through various activities. In fact, education management and human resource development can address the shortage of information and knowledge in a timely manner and lead to the horizontal growth of people in jobs by resorting to knowledge management system along with other resources to meet educational needs.

Schizophrenia has existed throughout history, as ancient Greek physicians have described it with different symptoms, but it was not seriously studied until the second half of the nineteenth century, and from the second half of the nineteenth century the classifications related to Schizophrenia developed, which of course was very personal and tasteful. Arnold pick was the first to use the term Dementia praecox to describe the apparently Hebephrenic type of psychiatric disorder. Schizophrenia is a mental disorder characterized by persistent or recurrent forms of psychosis. The main symptoms include hallucinations, delusions, and disordered thinking. Schizophrenia is a chronic and severe brain disease that affects a person's thoughts, feelings, and behaviors, as well as impairing a person's realism. The onset of the disease is between the ages of 16 and 30, but in rare cases it is also seen in childhood. The prevalence is equal in men and women, but the onset age is earlier in men than women. The age of onset in women is two peaks. The age of onset is 10 to 25 years for men and 25 to 35 years for women. The onset of the disease before the age of 10 and after the age of 60 is rare. In cases that start after the age of 45, it is called schizophrenia with a late onset.

At the end of 2019, several cases of pneumonia of unknown cause appeared in Wuhan, Hubei Province, China, which quickly spread to other provinces. China In the early stages, it was reported that most patients had a history of contact with Huan seafood. Patients were more likely to have a fever and cough symptoms. The spread of SARS-CoV-2 was very rapid. WHO has declared its prevalence as a public health emergency of international concern. On February 11, 2020, the International Committee for the Classification of Viruses renamed the virus "Acute Respiratory Syndrome of Coronavirus-2 (SARSCoV-2) and WHO SARS-CoV-2 Disease as Coronavirus 2019" (Covid-19 ) Declared an epidemic. The present study is a PICO review study that Epidemiological study of Covid-19 and risk factors. The browsing documents searched in the Google Scholar, Sid and Mag Iran databases were analyzed using the keywords epidemic, covid-19, risk factors. The COVID-19 epidemic has spread very rapidly to several countries, including European countries, Asian countries, the United States, and so on. Most countries, especially developing countries, expanded.

Breast cancer is defined as changes in the uncontrolled growth of cells in breast tissue that occur abnormally in the mammary glands (lobules) or in the ducts that connect the lobules to the nipple. The present study is an epidemiological study of breast cancer in Iran. The browsing documents searched in the Google Scholar, Sid and Mag Iran databases were analyzed using the keywords epidemic, cancer, breast. Based on the results obtained in this study, the incidence and death rate and burden of breast cancer in Iran has risen significantly, compared with previous years. Because of the vital role of women in the family, economy, health, development and other areas, early detection of breast cancer and its prevention according to its high prevalence around the world, as one of the best approaches to control this disease, is important.
