Optimized Research of Batch Query for Detailed Call Records

Menglin Liu, jianguang Liu

Abstract: For Telecom operators, the query for detailed call records is an important window to provide services for the outside world, which can provide the service for users or public, inspection, law and other units. For Shandong Unicom Corporation，due to the current query system of detailed call records can only achieve the query of a single number or batch numbers in a single account period, but it can’t achieve the query such as batch number in a multi-account period. In order to solve this problem, this paper proposes an optimization plan of batch query for detailed call records and gives the detailed implementation process, and batch inquiry for batch numbers in the multi-billing periods is achieved. Practice has proved that this optimization has achieved the batch query for detailed call records within a multi-account period ,and the implementation process is very simple, efficient, and the query results is fairly accurate, so it has a certain value of application and academic.

RSM-BASED Optimization of Enzymatic Hydrolysis Conditions for Chicken Bones

Shuqian Li

Abstract: The response surface methodology was used to study the enzymolysis technology of chicken bone and the enzymolysis technology model was established so as to obtain the optimum enzymatic hydrolysis technology conditions. Five factors, namely the size of bone, enzymolysis temperature, time of enzymolysis, solid-liquid ratio and quantity of enzyme were investigated using one way ANOVA. Then the model was established via response surface optimization. The results showed that the optimum enzymolysis conditions were: bone size: 1.9cm, the enzymolysis time 2.5h, and enzymolysis temperature 63℃， the obtained chicken bone enzymolysis production has an DEH of 0.921.

Study on Risk Factors of Mild Cognitive Impairment: Based on Decision Tree Model

Xiao Wang and Zongjun Guo

Abstract: Collect demographic, life and clinical factors of patients with mild cognitive impairment(MCI), analysis of MCI factors and set up high-risk factors model by use the decision tree data mining methods. 380 patients were selected from our hospital department of health and neurology clinic or hospital treatment during October 2014 to October 2016, The demographics, living habit of patients and Clinical factors were collected, C5.0 decision tree algorithm was adopted to establish the mild cognitive impairment risk factor prediction model, use the Logistic regression analysis and chi-square to assist the decision tree model. According to the decision tree model, the model prediction accuracy was 78.95%, age was the most important variable factors for MCI, sleep, exercise, diabetes, education, drinking were important variables to MCI. According to result of Logistic regression analysis, age, drinking, sleep were independent risk factors for MCI, the model prediction accuracy was 66.32%, results had significant difference (P<0.05). The decision tree model was superior to logistic regression model in the prediction accuracy for MCI happened, age, diabetes, drinking, insomnia were risk factors for MCI, exercise and education were the protective factors for the MCI.
