Abstract
Background and aim: This study aimed to investigate the effect of six weeks high intensity interval training (HIIT) and moderate intensity continuous training on health status in over weight males with nonalcoholic fatty liver disease (NAFLD).
Materials and Methods: Thirty overweight males with NAFLD were randomly divided into three groups included control (n=10), HIIT group (n=10), continuous training (CT) group (n=10). The HIIT included four sets of two minutes running with a 90-95% heart rate reserve and 3 minutes of active rest between each set; every week, a repeat was added to the workout. Continuous aerobic training included 20 minutes of running with an intensity of 70-85% heart rate reserve, which every week was added five minutes to the workout. Aerobic power, liver enzymes and lipid profiles were measured in serum by valid tools and data analyzed by co-variancetest.
Results: After six weeks of training program, the serum levels of ALT, AST, ALP, lipid profiles and degree of fatty liver sonography improved significantly in the experimental groups compared to the control group (P< 0/05). Increased HDL and decreased LDL, total Cholesterol, AST and ALT levels in HIIT group were significantly than the CT group (P<0/05). The improvement in maximum oxygen uptake was only significant in HIIT group than other groups (P<0/05).
Conclusion: Base on finding, HIIT compare with continuous training by better effects on aerobic power, lipid profiles and reduction of liver enzymes can be a good choice for patients with nonalcoholic fatty liver.

Abstract
Background and Aim: Considering the importance of knowledge management in the current era and the emphasis on the implementation of knowledge management in the health system in the knowledge management system of the Ministry of Health, Treatment and Medical Education, and since it is one of the first steps in the implementation of knowledge management, Drawing the knowledge tree of the organization, the purpose of the current research is to review the process of publishing the knowledge tree and examine it in the field of health.
Materials and Methods: The current research is a type of applied and descriptive review study that was carried out with the method of scientometrics and co-occurrence analysis of keywords. For this purpose, the term “Knowledge tree” OR “knowledge trees” was searched in Scopus reference database. For data analysis, the analyzes provided by the database itself were used, and VOSviewer software was used to visualize the data.
Results: The growth of scientific productions related to the field of the tree of knowledge in general in the mentioned base has started since 1979 and has had a growing trend until 2023. In the field of knowledge tree, among the authors Yang, Y, among the organizations, machine intelligence institute, iona college, and among the countries, China, America, and England have been at the top of the most productive in this field. Among the subjects, the most related articles are primarily related to the field of computer science (32.2 percent) and then to the field of engineering (22.1 percent) and mathematics (10.1 percent), which is significant. that medicine is in the sixth place and this is a sign of the weakness of producing resources in this field and the clustering resulting from the co-occurrence of keywords led to the identification of five clusters respectively with the titles of data mining and information processing, artificial intelligence and expert systems. , knowledge structure and decision support systems, semantics and knowledge representation, and finally learning and teaching systems.
Conclusion: The study of the thematic structure of scientific productions in the field of Knowledge Tree showed that the field of health has a weakness in the production of resources in this field. Therefore, it is necessary for future researches to pay special attention to the development and explanation of this concept and modeling its drawing, especially in the health system, in order to identify and prevent diseases.

Abstract
Background and Aim: The Iranian Red Crescent Society (IRCS) is recognized as one of the ten most powerful national societies among the Red Cross and Red Crescent societies globally in responding to disasters and emergencies. The purpose of this study is to outline the research topics of the Iranian Red Crescent Society by analyzing its scientific outputs over the past years.
Materials and Methods: The research is of an applied type with a scientometric approach and bibliometric analysis, which uses event network visualization techniques and synonym analysis. The statistical population of the study included all research conducted by the Iranian Red Crescent Society and articles indexed in the Scopus database since the 1990s. The synonym analysis of research titles conducted in the organization and article abstract information and data visualization techniques were used with VOSviewer, NVIVO, WordCloud and iThoughts software.
Results: The trend of publishing research outputs has been upward. Analysis of outputs showed that Shiraz University of Medical Sciences had the highest output and the Gastroenterology and Liver Research Center and Isfahan University of Medical Sciences had the lowest output among the 10 most active institutions. Also, the Iranian Red Crescent Medical Journal had the highest output, and among the topics related to outputs, the field of medicine was ranked first and the field of Multidisciplinary was ranked lowest. Among the frequently used words, “human” was ranked first. Identifying and drawing a map of research issues for this organization showed that the problem-oriented research topics of the Red Crescent Society were categorized into nine main areas, among which relief and rescue was ranked first with 21.4% and technology and innovation was ranked lowest with 4.6%.
Conclusion: The study of the scientific and research outputs of the Iranian Red Crescent indicates the breadth and diversity of research issues in the subject areas raised. The status of research conducted in the map of Iranian Red Crescent issues by comparing the keywords showed that the research performance of this organization is higher in the fields of health services, relief and rescue, and education. Given the breadth of issues commensurate with its missions, it needs balanced growth in research and knowledge production in other areas.
