Mayoritas guru-guru di SD N 10 dan SD N 2 Pondok Kelapa Kabupaten Bengkulu Tengah masih mengalami kesulitan bagaimana menyelenggarakan pembelajaran yang efektif, khususnya pembelajaran matematika. ...Sangat jarang mereka merencanakan pembelajaran matematika dengan pendekatan nyata yang mengaktifkan siswa, karena mereka menganggap bahwa pembelajaran yang demikian tidak bermanfaat, membingungkan dan menyita banyak waktu. Berdasarkan survei awal ditemukan bahwa di SD N 10 Pondok Kelapa, pembelajaran yang diselenggarakan oleh guru-guru matematika masih bersifat konvensional yaitu metode ceramah. Guru-guru sangat jarang menggunakan metode pembelajaran menyenangkan seperti pembelajaran berbasis STEAM dengan bantuan alat peraga, sehingga dalam kegiatan ini dilakukan kegiatan “Workshop Pembelajaran Matematika Berbasis STEAM (Science, Teknologi, Engineering, Art and Matematics) bagi Guru SD Pondok Kelapa. Metode yang digunakan dalam kegiatan ini meli?uti: Seminar, Demonstrasi, tanya jawab, diskusi, pemberian tugas terbimbing serta monitoring dan evaluasi. Guru-guru SD N Pondok kelapa Kabupaten Bengkulu Tengah pada awalnya sebanyak 100% belum memiliki pengetahuan pembelajaran STEAM dalam mata pelajaran matematika SD. Setelah workshop/seminar dilaksanakan dan setelah selesai kegiatan praktek pembuatan alat peraga pendukung STEAM, maka semua guru-guru sudah memiliki pengetahuan dan pemahaman yang baik tentang pembelajaran STEAM, secara umum respon guru terhadap kegiatan ini sangat baik (positif) serta motivasi mereka sangat tinggi. Mereka sangat antusias untuk menerapkan pembelajaran STEAM di sekolah.
Matematika merupakan salah satu mata pelajaran yang ditakuti oleh beberapa siswa. Hal-hal negatif muncul ketika berhadapan dengan matematika berupa rasa cemas. Kecemasan matematika merupakan salah ...satu faktor yang dapat mengganggu proses pembelajaran sehingga dapat mempengaruhi hasil belajar matematika siswa. Sehubungan dengan permasalahan tersebut, maka penulis melakukan penelitian terhadap siswa kelas V Sekolah Dasar Negeri 164 Pekanbaru dengan tujuan untuk mengetahui hubungan antara kecemasan dengan hasil belajar matematika siswa. Jenis penelitian yang digunakan adalah kuantitatif dengan motode penelitian korelasional. Jumlah populasi penelitian sebesar 148 siswa dan sampel penelitian sebesar 60 responden. Pengumpulan data dilakukan berupa angket dan dokumentasi hasil belajar matematika siswa kelas V. Berdasarkan hasil olahan data didapat koefisien korelasi sebesar -|0,297| dengan thitung sebesar 2,47 yang menunjukkan hubungan yang signifikan antara kecemasan dengan hasil belajar matematika siswa kelas V Sekolah Dasar Negeri 164 Pekanbaru yang mempunyai kekuatan hubungan lemah serta sifat hubungannya negatif. Penelitian ini menyimpulkan terdapat hubungan antara kecemasan dengan hasil belajar matematika siswa kelas V Sekolah Dasar Negeri 164 Pekanbaru.
This research aims to develop worksheets students (worksheets) based on this Mathematics Education (RME) to improve the matematical ability of elementary school student. The subject of this research ...is the students of class V Elementary School of Muneng and students in grade 5 Elementary School of Pulerejo 3. The type of this research is the Research and Development, with development model Four-D (4D), which is divided into 4 stages, namely : stage defining (define), stage design (design), development stage (· develop), spreading stage (disseminate). This research done only until the development phase (develop). The products of this research is a Worksheet Students (worksheets) based on this Mathematics Education (RME) a syllabus, denunciating, worksheets, and THB through Fax Banking. The results of the study showed that the average validity is 82,689% stated valid, the results of the average convenience of a limited test is 88,75% and field tests is 80.7% stated practical, and the results of the average effectiveness of limited test is 89,33% and field tests 86% is declared effective. Based on the results of research that the students work sheet (worksheets) based on this Mathematics Education (RME) on the matter arose space stated valid, practical, and effective and improve the matematical ability of elementary school student so that it can be used in the mathematics teaching.
Mathematical Programming, a branch of Operations Research, is perhaps the most efficient technique in making optimal decisions. It has a very wide application in the analysis of management problems, ...in business and industry, in economic studies, in military problems and in many other fields of our present day activities. In this keen competetive world, the problems are getting more and more complicated ahnd efforts are being made to deal with these challenging problems. This book presents from the origin to the recent developments in mathematical programming. The book has wide coverage and is self-contained. It is suitable both as a text and as a reference.* A wide ranging all encompasing overview of mathematical programming from its origins to recent developments * A result of over thirty years of teaching experience in this feild * A self-contained guide suitable both as a text and as a reference

•Fatty liver disease is a growing cause of cirrhosis and liver cancer globally.•Disease burden is expected to increase with the epidemics of obesity and diabetes.•Modeling shows slow ...growth in total cases and greater increase in advanced cases.•Mortality and advanced liver disease will more than double during 2016–2030.
Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) are increasingly a cause of cirrhosis and hepatocellular carcinoma globally. This burden is expected to increase as epidemics of obesity, diabetes and metabolic syndrome continue to grow. The goal of this analysis was to use a Markov model to forecast NAFLD disease burden using currently available data.
A model was used to estimate NAFLD and NASH disease progression in eight countries based on data for adult prevalence of obesity and type 2 diabetes mellitus (DM). Published estimates and expert consensus were used to build and validate the model projections.
If obesity and DM level off in the future, we project a modest growth in total NAFLD cases (0–30%), between 2016–2030, with the highest growth in China as a result of urbanization and the lowest growth in Japan as a result of a shrinking population. However, at the same time, NASH prevalence will increase 15–56%, while liver mortality and advanced liver disease will more than double as a result of an aging/increasing population.
NAFLD and NASH represent a large and growing public health problem and efforts to understand this epidemic and to mitigate the disease burden are needed. If obesity and DM continue to increase at current and historical rates, both NAFLD and NASH prevalence are expected to increase. Since both are reversible, public health campaigns to increase awareness and diagnosis, and to promote diet and exercise can help manage the growth in future disease burden.
Non-alcoholic fatty liver disease and non-alcoholic steatohepatitis can lead to advanced liver disease. Both conditions are becoming increasingly prevalent as the epidemics of obesity and diabetes continue to increase. A mathematical model was built to understand how the disease burden associated with non-alcoholic fatty liver disease and non-alcoholic steatohepatitis will change over time. Results suggest increasing cases of advanced liver disease and liver-related mortality in the coming years.
