Climate: Studies show that it is get warmer 2.10C in Mongolia in last 40 years. It influences ecology and decreased ecology event, succession action in ecosystem. It is interesting to study how climate change damage animal’s biology and ecology. The survey on changing ecology is rare conducted in Mongolia. Year average air temperature in Govi-Altai province got warmer 1.20C in last 30 years. Monitoring agency for meteorology and environment of Govi-Altai aimag summarized air temperature 1980-2009 (4-9 months) and it is got warmer 2.00C in Tonkhil soum.Plants: According to our research, at the above sea level around 2229-2600m dry steppe, at a.s.l 2601-2800m in steppe and water-meadow steppe at a.s.l 2801m high mountain steppe, zone plants grow. At the report of research for motion and episodic in epicenter of the marmot plague (1987-1991) aspect of plants figure by J.Batbold warm weather influence plants grow at around 100m.Animal spreading: In 1987-1991 M.sibirica spread almost part, S.erythrogenus above sea level 2300m in Ugalz mountains. Places where marmots live don’t have any marmots such as Alagiin hooloi, number of marmot is dramatically decreasing last years. It is related to climate change and hunting. Plants are changed due to influence climate animals in desert, dry steppe spread in Ugalz mountains and above sea level 2550m S.erythrogenus are according to the research, E.luteuse are spreading in front area of the Ugalz mountains, S.erythrogenus are spreading back of the Ugalz mountains.

: Researchers and scientists are developing practical clinical recommendations for behavioral and psychological treatments of chronic insomnia in adults. This also aims to create one of these recommendations.
To calculate the effects of insomnia, the research method used a decision tree based on the results of 10 questionnaires from 43 people suffering from insomnia who are patients at “Enerel” hospital in Bayanzurkh district. The study focused solely on individuals with insomnia, it serves as a decision tree to assist those experiencing insomnia-Indiviuals-Individual who do not have insomnia were excluded from the study. Method: We used a questionnaire method in this study. Conclusion All questionnaires pertain to the effects of insomnia when constructing a decision tree to produce insomnia effects as training data from 43 data points with 10 characteristics. It can be concluded with an average of five questions. If the training data is enhanced, it will get closer to reality. The decision tree will assist doctors and nurses in estimating, advising, and preventing the consequences of insomnia.
In the next phase, a survey will be conducted with individuals who have insomnia and those who have insomnia and those who do not, and an expanded decision tree will be developed.

Background: Hepatocellular carcinoma (HCC) is a primary liver cancer originating from liver cells, classified as a chronic liver disease. This cancer ranks third in the world in terms of mortality rate. The MELD (Model for End-Stage Liver Disease) and Child-Pugh scoring systems are utilized to assess the prognosis of chronic liver diseases. Based on studies suggesting that certain blood test indicators, particularly red cell distribution width (RDW), could be used to predict the prognosis of liver cancer and other cancers, as well as serve as diagnostic markers, this topic was chosen to evaluate the clinical significance of RDW in hepatocellular carcinoma. Aim: The aim is to study some blood test indicators and compare them with the MELD score and Child-Pugh score systems in order to determine the prognosis of chronic liver diseases. Materials and Methods: A retrospective, single-center, cross-sectional study was conducted at Mongolia-Japan Hospital. Among 322 patients diagnosed with HCC, 24 patients were selected for the case group, and 37 patients with liver cirrhosis were included in the control group. Results: According to the research criteria, 61 patients were selected and divided into 3 groups, and statistical analysis was performed. In the detailed blood test, platelet count and WBC count showed statistically significant differences among the 3 groups (p< 0.024). In the biochemical tests, C-reactive protein (CRP) was p< 0.018, total bilirubin p< 0.001, and the mean albumin level p< 0.015, all showing statistically significant differences among the 3 groups. A statistically significant inverse correlation was observed between RDW-CV and the clinical MELD score (r=-0.356). Conclusion Platelet count, RDW, CRP, total bilirubin, and average albumin levels are significantly different across the studied groups. RDW-CV shows a moderate inverse correlation with MELD scores, suggesting its potential as a prognostic marker in chronic liver diseases. Further research with larger sample sizes is recommended to confirm these findings.
