This study aims to determine the description of the mathematical connection ability of class XI MIPA students based on the learning styles of students of convergers, divergers, accommodators, and assimilators in online learning using discovery-based worksheets. This type of research is a qualitative descriptive study. The subjects of the study were the students of class XI MIPA SMAN 17 Pandeglang. Data collection is done through learning style questionnaires, tests of mathematical connection abilities, and interviews. All students of class XI MIPA were identified by the type of learning style using the Kolb learning style questionnaire. Data about mathematical connection ability is analyzed with interview data. 8 students consisting of 2 students representing learning styles were selected to interview their mathematical connection abilities. Based on the analysis of the data obtained a description of the results of research that in general students of the type of converger, diverger, accomodator, and assimilator have good mathematical connection abilities. the assimilator type is rather weak on the indicator using the mathematical connection ability indicator. As for the type of accomodation learning style, it is rather weak in finding and understanding concepts in mathematical connection abilities. Students of the Converger learning style style and assimilator understand the material by reading and observing in the ongoing learning while students of the Diverger learning style type and the accomodator understand the concepts in general by following the learning process in progress and actively trying to try in working on the discovery-based worksheets.

Aims: To evaluate the association of Nuclear factor kappa B1(NFkB1) gene polymorphism with inflammatory markers Urinary Monocyte Chemoattractant Protein 1 (UMCP1) and Tumor Necrosis Factor alfa (TNF alfa) in Patients of diabetes mellitus with or without renal involvement in Eastern India. Material and Methods: Consecutive Patients of Type 2 Diabetes Mellitus (DM) with or without microalbuminuria attending SCB MEDICAL COLLEGE and HOSPITAL Medical OPDs in between September 2018 to September 2019 were recruited in this study. Patients were subjected to blood and urine investigations. DNA extraction and Restriction fragment Length Polymorphism (RFLP) was done in Department of Biochemistry. Controls were unrelated healthy attendants with no history of Diabetes Mellitus, HTN, Chronic Kidney Disease (CKD). Results: Mean Systolic BP, Fasting Blood Glucose, Post Prandial Blood Glucose, HBA1c, Total Cholesterol were significantly higher in diabetes mellitus and diabetic nephropathy groups than control group. Estimated Glomerular Filtration Rate was significantly lower in diabetic nephropathy (p value < 0.001). UMCP1, Urinary Albumin Creatinine Ratio, TNF alfa were higher in diabetes mellitus and nephropathy with p value (<0.001, 0.006 < 0.001) respectively. In between DM and Diabetic Nephropathy groups nfkb1 gene expression, umcp1 and tnf alfa levels were significantly increased in Diabetic nephropathy with p value 0.019, <0.01, 0.001 respectively. Insertion/insertion NFkB1 gene polymorphisms were more in diabetic nephropathy group and were positively correlated with inflammatory markers UMCP1 (r = 0.517, p < 0.01) and TNF alfa (r = 0.172, p = 0.19). Conclusion: insertion/insertion NFkB1 gene polymorphism increases the risk of nephropathy by 2.52 times (OR = 2.52, 95% CI: 0.04 - 0.63, p value = 0.019) in diabetes patients in eastern India.

Prevalence of diabetes and prediabetes, as well as cardiovascular disease is very high among Veterans. The aim of the study is to evaluate the rate of progression of prediabetes and the factors associated with progression to diabetes. This is an observational, retrospective data-base study of progression of prediabetes to diabetes at Veterans Health Administration at Columbia, South Carolina, diagnosed between 2008 and 2019 based on HbA1C (5.7 to 6.4). We calculated the time interval to progress to diabetes from the date of baseline data, and then the percentage of subjects progressed to diabetes is calculated as 1st year, 2nd year and so on. Statistical analysis included descriptive statistics and correlation of parameters with progression to diabetes. Subjects with prediabetes identified include 72,604 with mean age 66 and mean HbA1C of 5.9. Among the study population, only 8% were women. Association of hypertension was 55% and atherosclerotic coronary artery disease was 13%. Among the study population, 10,710 subjects did not have follow up. Among 61,894 prediabetics 21,954 (35%) progressed to diabetes, while 39,940 (65%) remained as prediabetic. Those progressed to diabetes had relatively higher HbA1C and associated with higher prevalence of atherosclerotic cardiovascular disease, hypertension and are older by age. About 60% of those progressed to diabetes are within 2 years from baseline. We conclude that aggressive measures are necessary to prevent progression to diabetes to decrease the morbidity associated with diabetes and health care burden. It is essential to identify those progress to diabetes, such as biomarker evaluation.

Introduction: Erectile dysfunction (ED) is a common complication of diabetes mellitus (DM) that is associated with poor quality of life and can be present in type 2 diabetics at the time of diagnosis. There are common risk factors associated with erectile dysfunction in type 2 diabetic subjects. Some of these are potentially treatable or reversible. The risk factors evaluated by this study included glycaemic control, duration of diabetes, obesity, peripheral artery disease (PAD), hypertension and antihypertensive medications use. Materials and Methods: This study was a cross sectional one carried out over a period of six months (June-November, 2016) at the diabetes clinic of the Nnamdi Azikiwe University Teaching Hospital, Nnewi and involved 124 subjects with type 2 diabetes mellitus. A convenience sampling method was used. A detailed physical examination, blood pressure and anthropometric measurements and vascular assessment with a hand-held doppler ultrasound were carried out. Data was collected using a study proforma. Erectile dysfunction was diagnosed with the International Index of Erectile Function questionnaire while anxiety and depression were diagnosed with the Hospital Anxiety and Depression questionnaires. Subjects that had anxiety/depression or hypogonadism were excluded from the study. Results: A total of 124 subjects were studied, 48.4% of whom had erectile dysfunction. Glycaemic control was significantly associated with ED among the subjects (OR = 0.198, 95% CI = 0.081 - 0.483, P 0.05). Conclusion: Poor glycaemic control and presence of PAD significantly increase the risk of ED in male subjects with type 2 DM, thus underscoring the need for an early screening and treatment of these predictors of erectile dysfunction.

Background: Teachers are the cornerstone of the next generation and they are considered an important source of health information for students about diabetes. The objective of this study is to assess the knowledge, attitude, and practice (KAP) of teachers about diabetes mellitus (DM) and to identify the associated factors. Methods: Cross-sectional study design included a stratified random sample of male and female teachers from public and private schools in Riyadh city. A self-administered online questionnaire was developed. The data collection was from October to November 2019. Results: The study included 633 teachers. Overall, 57.2% of the surveyed teachers were knowledgeable about DM. Teachers aged between 51 and 60 years (p = 0.005), males (p = 0.018), PhD holders (p = 0.011), teaching science (p = 0.021), having more than 20 years of teaching experience (p = 0.001), diabetics (p < 0.001), and having family history of diabetes (p = 0.007) had the highest level of knowledge. Overall, positive attitude towards DM was reported among 53.1% of the teachers. Those with teaching experience between 11 and 15 years (p = 0.024), diabetics (p = 0.029), and having a diabetic student (p = 0.012) had more positive attitude towards diabetes. Good diabetes-related practice was observed among 54.3% of the teachers. Older (p < 0.001), having more than 20 years of teaching experience (p < 0.001), non-Saudi (p = 0.011), diabetic teachers with longer duration of the disease (p < 0.001), having family history of DM (p = 0.028), and principals (p = 0.002) had the highest level of good diabetes-related practice. Conclusion: The KAP of teachers in public and private schools in Riyadh about DM was sufficient in many aspects. However, targeting new young teachers should be a priority to raise awareness.

Pedagogical content knowledge is a combination of understanding of teaching material (content knowledge) and understanding how to educate (pedagogical knowledge) that needs to be possessed by a teacher. The purpose of this study was to determine the pedagogical content knowledge concept, the achievement of pedagogical content knowledge for prospective teacher students, and to determine the role of prospective mathematics teacher students towards pedagogical content knowledge. A teacher in carrying out his professional assignments must have the competence that is always maintained. Because of this, competency development is an important requirement to ensure that the quality of learning in the classroom adjusts to the development and demands of the times. Always maintained competence also ensures that the implementation of education is consistent in achieving educational goals. There are ten pedagogical content knowledge criteria that must be possessed by prospective teacher students before conducting the practice in the field. Prospective teacher students must also be able to implement learning, knowledge of ways to represent and explain the material to make the material understandable to others.

The purpose of this study is to improve the mathematical problem-solving ability of students in class VII-1 MTs Islamiyah Medan through the STAD type cooperative learning model. This research is a Class Action Research (CAR). The subjects of this study were 40 students of grade VII-1 MTs Islamiyah Medan. The object in this study is to improve students' mathematical problem-solving abilities through the STAD Type Cooperative learning model on the subject of rectangular flat shapes. This research instrument uses tests of mathematical problem-solving abilities, observation, and interviews. Based on the preliminary results of the interviews conducted with the mathematics teacher, it was obtained that the mathematical problem-solving ability of students in class VII-1 MTs Islamiyah Medan was still not optimal. From the data obtained only 17.5% of students met the mathematical problem-solving ability criteria. This research was conducted in two cycles by providing treatment using STAD learning. Based on the results of data analysis students' mathematical problem-solving abilities in the first cycle obtained that 70% of students meet the criteria. But because it has not reached 85% completeness then continued with the second cycle. In the second cycle, 90% of students who met the criteria of mathematical problem-solving ability were obtained.

This research is a Class Action Research (CAR). The subjects of this study were 40 students of grade VII-1 MTs Islamiyah Medan. The object in this study is to improve students' mathematical problem-solving abilities through the STAD Type Cooperative learning model on the subject of rectangular flat shapes. This research instrument uses tests of mathematical problem-solving abilities, observation, and interviews. Based on the preliminary results of the interviews conducted with the mathematics teacher, it was obtained that the mathematical problem-solving ability of students in class VII-1 MTs Islamiyah Medan was still not optimal. From the data obtained only 17.5% of students met the mathematical problem-solving ability criteria. This research was conducted in two cycles by providing treatment using STAD learning. Based on the results of data analysis students' mathematical problem-solving abilities in the first cycle obtained that 70% of students meet the criteria. But because it has not reached 85% completeness then continued with the second cycle. In the second cycle, 90% of students who met the criteria of mathematical problem-solving ability were obtained. The conclusion of this study is an increase in students' mathematical problem-solving abilities from cycle I to cycle II.","PeriodicalId":51086,"journal":{"name":"Journal of Database Management","volume":"1 1","pages":"33-40"},"PeriodicalIF":2.6,"publicationDate":"2020-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47954533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ability of students to represent mathematical expressions related to HOTS problems is still not good. This study aims to describe the representation of the mathematical expression of students in solving HOTS problems. This type of descriptive research using a qualitative approach in terms of aspects of the representation of mathematical expressions. The subjects of this study were 17 Civil Engineering students who were taking lectures in the academic year 2018/2019. The data collection technique in this research is the test item description. The instrument used was in the form of a test sheet. Data analysis was carried out through three stages: data reduction, data presentation, and conclusion drawing. The results showed that students could involve mathematical symbols correctly and appropriately in each stage of solving HOTS analysis type questions. Students can present other mathematical representations into mathematical expression representations and involve mathematical symbols correctly and appropriately in each stage of HOTS problem solving, both Evaluation type and Creating type.
