One of the evaluation standards given by the National Council of Teachers of Mathematics (NCTM) is mathematical disposition. Disposition refers not simply to attitudes but to a tendency to think and to act in positive ways. Creative thinking disposition is the tendency to thinking and acting creatively in mathematics. The aims of this research is to determine the effect of mathematical habits of mind learning based on problems toward the students' mathematical creative thinking disposition. This research was conducted at one of SMPN (Junior High School) Padang Ratu, Indonesia. The method used in this research is quasi experiment with posttest only control group research design. The population of this research is 214 students. The sample of this study is 70 students at grade VII which consists of 36 students in experimental group and 34 students in control group. The experimental group was taught by mathematical habists of mind learning strategy based on problem and the control group was taught by conventional learning strategy (teacher centered). The sampling technique used is cluster random sampling. The instrument used to collect data in this research is questionaire checklist to determine students' mathematical creative thinking disposition. Data analysis used in this research is t-test. The results showed that students' mathematical creative thinking disposition which is taught by mathematical habits of mind learning strategy based on problem are better than the students which taught by conventional learning strategy. In future research, we recommend to use the mathematical habits of mind learning strategy based on problem in learning process to increase student's creative thinking disposition.

Background: Diabetes mellitus (DM) is a serious chronic disease, caused by the inability of the pancreas to produce enough insulin. It is estimated that people with diabetic are at twice the risk of anxiety compared to the general population. Diabetic patients with anxiety has been related to increasing risk of comorbidities, which can interfere with daily living activities, and life quality, increased health costs, and many other complication when compared with the general population. Method: This study is a predictive type multivariate study, with a cross-sectional approach to 111 subjects in the outpatient clinic of Universitas Sumatera Utara hospital. The tests carried out in this study were the bivariate test, multivariate linear regression test to determine what factors are related to anxiety scores in DM patients, using the Hospital Anxiety and Depression Scale (HADS-A) as measurement tool. Results: After conducting the multivariate analysis test, it was found that the variables associated with anxiety scores in people with DM were length of education (p <0.001), Body Mass Index (p <0.001), duration of illness (p <0.001), work status (p <0.001), comorbidity (p = 0.021). Conclusion: By knowing the factors that influence anxiety scores in people with DM, it is hoped that clinicians will pay more attention to the symptoms of anxiety in people with DM, especially in the early days of diagnosis so that intervention can be carried out.
