Authors: Rasoulzadegan Mohammad Hossein , Soltani Hamid Reza , Rahmanian Masoud , Amid Nakisa
Published: October 2018

Introduction: Insulin resistance has a strong relationship with the incidence of type II diabetes. It also has a direct relationship with other risk factors of diabetes, which together are known as metabolic syndrome. The aim of this study was to investigate the relationship between insulin resistance and hypertension.Materials and Methods: In this historical cohort study, 90 patients were divided into three different groups: those without hypertension, those with controlled hypertension, and those with uncontrolled hypertension. Systolic and diastolic blood pressure, body mass index, and laboratory test results such as cholesterol, triglycerides, low- density lipoprotein, high-density lipoprotein, fasting plasma glucose, and fasting plasma insulin were compared among the three groups. Data were analyzed with t-tests and the analysis of variance test, which were performed using statistical package for the social sciences version 20 software.Results: Age and sex were the same among the three groups; however, BMI, systolic blood pressure, and diastolic blood pressure in the uncontrolled-hypertension group were higher than in the controlled-hypertension and without-hypertension groups (P<0.05). Lipid profile (P<0.05), creatinine (P=0.77), and uric acid (P=0.233) were not significantly different among the groups, although fasting plasma insulin (P=0.012) and homeostatic model assessment of insulin resistance (P=0.038) were significantly higher in the uncontrolled-hypertension group than in the other groups.Conclusion: Homeostasis model assessment of insulin resistance in patients with uncontrolled hypertension was higher than in patients with controlled hypertension and those without hypertension. Therefore, homeostatic model assessment of insulin resistance can be used as a predictive clinical test for the early diagnosis of diabetes in patients with uncontrolled hypertension.

Proses markov adalah suatu keadaan dimana apabila state pada masa yang akan datang dari proses tidak tergantung pada masa yang telah lalu, melainkan hanya bergantung pada masa sekarang saja. Jika jangka waktu proses berada pada setiap keadaan sebelum pindah adalah sama dengan satu satuan, maka proses semi Markov tak lain adalah rantai Markov. Perhitungan proporsi waktu dari sebuah mesin untuk masing-masing keadaan mesin pada kondisi baik, kondisi sedang, atau kondisi rusak, dapat dilakukan dengan menggunakan konsep proses semi Markov.
Implementasi Pendidikan Karakter Dalam Pembelajaran Matematika Melalui Pendekatan Konstektual
Authors: Yuniati Suci
Published: October 2018

Pembentukan karakter siswa sesungguhnya sudah tertuang dalam fungsi dan tujuan pendidikan nasional, namun fungsi dan tujuan pendidikan nasional seolah-seolah gagal dilaksanakan. Salah satu gagalnya penerapan tujuan dan fungsi pendidikan nasional dapat dilihat dari kondisi pendidikan di sekolah saat ini yang cenderung mengembangkan aspek kognitif siswa, dimana aspek selain kognitif seperti afektif kurang mendapat perhatian. Hal ini menyebabkan rendahnya karakter positif siswa yang menyebabkan adanya tawuran antar siswa, penggunaan narkoba, pergaulan bebas, penuturan bahasa yang buruk, tidak santun, suka melangkar aturan, egois, pornografi yang terjadi dikalangan siswa, dan lain sebagainya. Melihat fenomena tersebut di atas maka perlu adanya penerapan pendidikan karakter, pendidikan karakter di sekolah dapat dikembangkan melalui pengalaman belajar dan proses pembelajaran yang bermuara pada pembentukan karakter dalam diri siswa. Pendidikan karakter dalam kegiatan belajar mengajar di kelas, dilaksanakan menggunakan pendekatan terintegrasi dalam semua mata pelajaran. Pendidikan karakter diberikan secara terpadu melalui pengenalan nilai-nilai, fasilitas kesadaran akan pentingnya nilai-nilai, dan penginternalisasian nilai-nilai kedalam tingkah laku siswa sehari-hari, baik di dalam maupun di luar kelas. Pada dasarnya kegiatan pembelajaran matematika, selain menjadikan siswa menguasai kompetensi (materi) yang ditargetkan, juga dirancang untuk menjadikan siswa mengenal, menyadari/peduli, dan menginternalisasi nilai-nilai dan menjadikan perilaku. Nilai-nilai karakter yang dapat dikembangkan adalah berfikir kritis dan logis, rasa ingin tahu, toleransi, bertanggung jawab, mandiri, kreatif, jujur, menghargai karya dan prestasi orang lain, dan disiplin. Kegiatan pembelajaran matematika dalam kerangka pengembangan karakter siswa dapat menggunakan berbagai pendekatan. Diantaranya pendekatan kontekstual sebagai konsep belajar dan mengajar yang membantu guru dan siswa mengaitkan antara materi yang diajarkan, dengan situasi dunia nyata. Sehingga, siswa mampu untuk membuat hubungan antara pengetahuan yang dimilikinya dengan penerapannya dalam kehidupan siswa. Dengan begitu, siswa memiliki hasil yang komprehensif tidak hanya pada tataran kognitif tetapi pada tataran afektif serta psikomotor.

Dasar-Dasar Pendidikan Islam Hubungannya Dengan Matematika
Authors: Hasri Hasri
Published: October 2018

Pendidikan merupakan suatu proses generasi muda untuk dapat menjalankan kehidupan dan memenuhi tujuan hidupnya secara lebih efektif dan efisien. Pendidikan lebih daripada pengajaran, karena pengajaran sebagai suatu proses transfer ilmu belaka, sedang pendidikan merupakan transformasi nilai dan pembentukan kepribadian dengan segala aspek yang dicakupnya. Perbedaan pendidikan dan pengajaran terletak pada penekanan pendidikan terhadap pembentukan kesadaran dan kepribadian anak didik di samping transfer ilmu dan keahlian. Hal inilah yang membedakan antara Islam dengan Barat. Al-Quran merupakan petunjuk buat umat manusia. Petunjuk tidak hanya berkaitan dengan syariat agama tetapi berkaitan pula dengan ayat-ayat kauniyah yang erat sekali dengan ilmu pengetahuan. Al-Quran juga mengungkap tentang asal mula kehidupan, siklus air, peredaran benda-benda langit, astronomi dll yang dapat menginspirasi perkembangan ilmu pengetahuan alam dan sains. Bahkan matematikapun banyak terdapat dalam ayat-ayat Al-Quran. Penciptaan alam semesta ini melalui perhitungan yang sangat detail oleh Allah SWT. Sehingga, sebenarnya Allah telah menurunkan matematika melalui ayat-ayat Al-Quran, namun kebanyakan manusia tidak menyadarinya. Demikian pula sebaliknya apakah dalam matematika memuat pula sifat-sifat agamis yang dapat menjadi karakter kepribadian manusia dalam hidup sehari-hari.
Representasi Matematika Al-Qur�an Melalui Teori Graf
Authors: Nursupiamin Nursupiamin
Published: October 2018

Dalam Al-Quran, Allah SWT menyajikan begitu banyak isyarat salah satunya hitungan atau matematika. Pada tulisan ini, akan dipaparkan representasi matematika Al-Quran melalui teori graf khususnya yang berkaitan dengan surah prima atau surah Al-Quran yang jumlah ayatnya merupakan bilangan prima. Adapun hasil yang diperoleh berupa digraph dengan 29 simpul terpencil (29 graf kosong) dan 3 simpul membentuk sebuah graf sederhana yang memiliki makna diantaranya : (1) Persamaan yang terkandung antara surah Al-Mumtahanah (surah ke 60), surah Ar-Rad (surah ke 13), dan surah Az-Zukhruf (surah ke 43) adalah untuk menjauhi atau tidak bergaul dengan orang-orang yang tidak beriman kepada Allah swt dan rasulNya dan mencegah perbuatan yang mungkar; (2) Bila dipandang secara geometri, besarnya sudut yang terbentuk mendekati 90o dan memiliki kemiripan bentuk dengan segitiga siku-siku; (3) Bila dipandang secara aljabar, jika ketiga titik (60,13), (13,43), dan (43,89) dinyatakan sebagai angka 601313434389, 60134389, 6013, 1343, dan 4389 maka angka tersebut merupakan kelipatan dari bilangan prima khusus seperti 7, 17 dan 19; dan (4) Bila dipandang secara teori graf, digraph yang terbentuk membuktikan bahwa untuk graf berarah pada digraph surah prima Al-Quran menunjukkan banyaknya simpul yang berderajat ganjil selalu genap. Sehingga representasi graf pada surah Al-Quran yang memiliki jumlah ayat bilangan prima menunjukkan bukti bahwa Al-Quran diturunkan dengan aturan tertentu yang menguak ada matematika dalam Al-Quran.
Investigasi Dalam Proses Pembelajaran Matematika
Authors: Abrar A Ika Prasasti
Published: October 2018

Di Inggris istilah investigasi (penyelidikan) mulai muncul di kancah pembicaraan para guru sejak diterbitkannya laporan Cockcroft pada tahun 1982 yang menyatakan bahwa pengajaran matematika harus melibatkan aktivitas-aktivitas berikut: Eksposisi atau pemaparan guru (exsposition); Diskusi di antara siswa sendiri, ataupun antara siswa dengan guru (discussion); Kerja praktek (practical work); Pemantapan dan latihan pengerjaan soal (consolidation); Pemecahan masalah (problem solving); Penyelidikan (investigation). pemecahan masalah merupakan kegiatan memusat (convergent activity) dimana para siswa harus belajar mencari penyelesaian yang sudah jelas arahnya, sedangkan investigasi adalah suatu kegiatan menyebar (divergent activity) dimana para siswa lebih diberikan kesempatan untuk memikirkan, mengembangkan, dan menyelidiki hal-hal yang menarik yang mengusik rasa keingintahuan mereka.

Background/Aim: The aim was to evaluate Diabetes Mellitus (DM) patients' awareness of their risk for oral and dental complications, to evaluate their oral health behaviors, assess their sources of related information, and to detect the influence of their awareness on oral health and dental management. Material and Methods: Total of 240 DM patients presenting to a university outpatient dental facility for routine care completed a self-administered questionnaire about demographic socioeconomic characteristics, oral health care and awareness on oral complications of DM. Dental status of each patient was recorded. Data were analyzed with Chi- square test; p was set as 0.05. Results: The patients' mean age was 52.85 years; the majority had Type 2 DM (72.1%) and 61.7% were females. Two thirds of the patients had tooth loss; 65% brushed daily and used toothpick for interproximal cleaning (35%). Only 12.9% had regular dental visits and 37.5% reported their oral health as 'poor'. DM patients rarely received guidance from their health care professionals regarding their oral health (28.3%). Even though 62.5% were aware of oral complications of DM, only 46.3% knew that oral health may affect DM. The patients with Type 1 and Type 2 DM had similar perceptions about their oral health status (p=0.15>0.05). However, insulin users were more aware of the interaction between oral health and DM (p>0.05), and were more likely to consider their oral health as 'poor' (p>0.05). Conclusions: DM patients' awareness of the effect of DM on oral health was higher than that of the effect of oral health on DM management. Medical health care providers were failing to provide the necessary information regarding these issues when compared to dentists.

Published: October 2018

Background/Aim: To determine the prevalence of single-rooted mandibular second molars in a Greek population and examine their internal morphology with the aid of intraoral periapical radiography. Material and Methods: Clinical records of 531 root-canal treated permanent single-rooted mandibular second molars were collected from the Postgraduate Clinic of the Department of Endodontology, Dental School, Aristotle University of Thessaloniki, Greece and from private dental clinics in the same city. The clinical records, along with the radiographic examination, were evaluated to determine the overall frequency of single-rooted mandibular second molars together with the number of root canals and their course. The root canals were categorized using Vertucci's classification with the addition of 3 further types where appropriate. Results: Out of 531 mandibular second molars; 102 (19.2%) presented a single root; 427 (80.4%) presented two roots; 2 (0.4%) presented three roots. In a total of 102 single-rooted mandibular second molars 31 (30.3%) presented with Type I, 18 (17.6%) with Type II, 14 (13.7%) with Type IV, 7 (7%) with 3 additional root canal types and 32 (31.4%) with a C-shaped root canal system. Conclusions: One out five mandibular second molars was single-rooted in a Greek population. The internal morphology of these teeth can be very complex with regard to the numbers and courses of root canals.
Management of large residual cyst in elderly patient with decompression alone: Case report
Authors: Torul Damla , Bereket Cihan , Özkan Enes
Published: October 2018

Background/Aim: Residual cysts comprise approximately 10% of all odontogenic cysts. They are more commonly seen in 4th-6th decades of life, and occur due to incomplete previous surgical removal of a radicular cyst; or due to left epithelial remnants stimulated by tooth extraction. These lesions are often treated with enucleation. However, this procedure is not always the ideal treatment solution for elderly people due to the presence of physical and mental disorders, and risk of jaw fracture. Case Report: In this case report, the successful treatment of a large residual cyst in the symphysis of a 93 year-old female patient by performing decompression alone is presented. A plastic drain was placed on the wall of the cyst to allow irrigation. Regeneration was observed in the cyst cavity 3 months after surgery. The 1-year follow up showed that the majority of the cyst cavity was filled with new bone. Conclusions: In elderly patients, large inflammatory cysts can be successfully treated with decompression considering the limited regeneration capacity and difficulties in follow-up.

Published: October 2018

Floating-Harbor syndrome (FHS) is a rare autosomal dominant syndrome characterized by short stature with delayed bone age, retarded speech development, intellectual disability and dysmorphic facial features. Recently, dominant mutations almost exclusively clustered in the final exon of the Snf2-related CREBBP activator protein (SRCAP) gene were identified to cause FHS. Here, we report a boy with short stature, speech delay, mild intellectual disability, dysmorphic features, and with genetically confirmed FHS. To the best of our knowledge, this is the first molecularly confirmed case with this syndrome reported in Romania. An intensive program of cognitive and speech stimulation, as well as yearly neurological, psychological, ophthalmological, otorhinolaryngological, pediatric and endocrinological monitoring for our patient were designed. We propose a checklist of clinical features suggestive of FHS, based on the main clinical features, in order to facilitate the diagnosis and clinical management of this rare condition.
The mitochondrial tRNAGly T10003C mutation may not be associated with diabetes mellitus
Authors: Yuan Q , Zhao ZG , Yuan HJ
Published: October 2018

Mitochondrial DNA (mtDNA) mutations have long been proposed to play important roles in the pathogenesis of diabetes mellitus (DM). A large proportion of these mutations are localized at the mt-tRNA genes. Owing to its high mutation rate, a growing number of mt-tRNA mutations have been reported; however some of them are neutral genetic polymorphisms and will not result in the alteration of the mitochondrial function responsible for DM. In this study, we reassessed a recent reported “pathogenic” mutation, tRNAGly T10003C, in a clinical manifestation of DM. We first performed the conservation assessment of this mutation between different species. Moreover, the bioinformatics analysis was used to predict the secondary structure of mt-tRNAGly in wild type version and the mutant carrying the T10003C mutation. We also screened the presence of the T10003C mutation in 500 unrelated DM patients and 300 healthy controls. We noticed that the T10003C mutation was not very conserved and did not cause the secondary structure change of mt-tRNAGly. Moreover, this mutation was absent in the 500 unrelated DM patients and controls, suggesting that this mutation may be a rare event in the human population. In conclusion, the current study showed no association between the T10003C mutation and DM in humans.

Authors: Deshko Lyudmyla
Published: October 2018

This article lists the content and deals with the criteria for assessing the presence or absence of material damage suffered by the applicant to the European Court of Human Rights, the subject of entrepreneurship, as a new condition for the admissibility of an individual application. The article establishes that the list and content of the criteria for assessing the presence or absence of material damage suffered by the applicant to the European Court of Human Rights are different for individuals and for legal entities – business entities. Moreover, the article initiates a discussion on the list and content of these criteria for the subjects of entrepreneurship – the applicants to the European Court of Human Rights. In the light of the Court’s practice, the author reveals their content as well as legal categories such as ‘substantial harm’, ‘financial harm’, ‘pecuniary damage’, ‘non-pecuniary damage’ incurred by the applicant, the subject of entrepreneurship, and highlights the issues to which objectives may be caused by ‘moral harm’ in case of violation of the rights of the subject of entrepreneurship.
