The reality on the ground shows that students' ability to make mathematical connections is still relatively low. The purpose of this study was to determine the ability of mathematical connections based on the mathematical disposition of students on the material of a two-variable linear equation system in Jayaraga village. The population in this study were students of SMP/MTs equivalent in Jayaraga village, while the sample was selected based on a purposive sampling technique of 3 students. The analysis of the results of this study shows that the mathematical connection ability and mathematical disposition: (1) The students' mathematical connection ability and mathematical disposition are in the medium category. (2) The level of mathematical disposition ability tends to affect the level of students' mathematical connection abilities. Students who have a high level of mathematical disposition ability tend to have better mathematical connection abilities. Students who have a moderate level of mathematical disposition ability tend to have ordinary mathematical connection abilities. And students who have a low level of mathematical disposition skills tend to have low mathematical connection abilities. Kenyataan di lapangan menunjukkan bahwa kemampuan siswa dalam melakukan koneksi matematis masih tergolong rendah. Tujuan penelitian ini adalah untuk mengetahui kemampuan koneksi matematis berdasarkan disposisi matematik siswa pada materi sistem persamaan linear dua variabel di desa Jayaraga. Populasi dalam penelitian ini adalah siswa SMP/MTs sederajat yang berada di desa jayaraga, sedangkan sampel dipilih berdasarkan teknik purposive sampling sebanyak 3 orang siswa. Analisis hasil penelitian ini menunjukkan bahwa kemampuan koneksi matematis dan disposisi matematik: (1) Kemampuan koneksi matematis dan disposisi matematik siswa masing-masing termasuk ke dalam kategori sedang.

In reality, mathematical communication skills and lack of trust in students in Indonesia are still relatively low. Indications of low mathematical communication skills are seen from the results of a survey conducted by the OECD that shows that students' ability in mathematics learning is at a low level. Indications of weak self-confidence in learners are when students lack confidence when asked to express their opinions on the concept of normality discussed. The purpose of the researcher is to know the mathematical communication skills and self-confidence of students in the material of the three-variable linear equation system. This study was conducted on high school students in the Sukaresmi area with 6 students sampled. The findings in this study include the mathematical communication skills of each student in the SPLTV materials vary, including students with low, medium, and high mathematical communication skills. Furthermore, the achievement of self-confidence in students can also be seen from the level of interpretation obtained by students, namely moderate and high. Students with high self-confidence interpretation tend not to understand the advantages or disadvantages that they have, while students with self-confidence interpretation are not confident in their own abilities, are anxious about solving problems, feel depressed, and tend to be irresponsible. Pada kenyataannya kemampuan komunikasi matematis dan kurangnya rasa percaya pada peserta didik di Indonesia masih tergolong rendah. Indikasi rendahnya kemampuan komunikasi matematis dilihat dari hasil survei yang dilakukan oleh OECD yang menunjukan bahwa kemampuan siswa dalam pembelajaran matematika berada pada level yang rendah. Indikasi lemahnya self-confidence peserta didik adalah saat peserta didik kurang percaya diri ketika diminta untuk mengemukakan pendapatnya mengenai konsep kematematikaan yang dibahas. Adapun tujuan dari penelitian tersebut yaitu untuk mengetahui kemampuan komunikasi matematis dan self-confidence siswa pada materi sistem persamaan linear tiga variabel. Penelitian ini dilakukan pada siswa tingkat SMA/Sederjat di daerah Sukaresmi dengan 6 orang siswa yang dijadikan sampel. Hasil temuan dalam penelitian ini diantaranya kemampuan komunikasi matematis setiap siswa pada materi SPLTV berbeda-beda, diantaranya siswa dengan kemampuan komunikasi matematis rendah, sedang, dan tinggi. Selanjutnya pencapaian self-confidence pada siswa juga dapat dilihat dari tingkat interpretasi yang diperoleh oleh siswa yaitu sedang dan tinggi. Siswa dengan interpretasi self-confidence yang tinggi cenderung tidak memahami kelebihan maupun kekurangan yang dimilikinya, sedangkan siswa dengan interpretasi self-confidence yang sedang kurang percaya pada kemampuan dirinya sendiri, cemas dalam menyelesaikan permasalahan, merasa tertekan serta cenderung tidak bertanggung jawab.

Published: November 2022

Background: Fine Needle Aspiration Cytology (FNAC) has been widely accepted as an accurate and minimally invasive diagnostic procedure in the investigations of salivary gland masses. The aim of this study was to determine the accuracy of FNAC in the diagnosis of pleomorphic adenoma. Materials and methods: A cross sectional comparative study was carried out on a total of 28 patients with salivary gland swellings who underwent preoperative FNA examination. After surgical excision of tumours, all FNAC findings were subsequently verified with histopathological examination. All the necessary and relevant data were recorded methodically and meticulously and statistical analysis was done by computer software device (SPSS-18 version). Results: On preoperative FNA examination, among the 28 cases, 19 (67.9%) cases were pleomorphic adenomas. On histopathological examination, out of 28 cases, 20 (71.4%) cases were pleomorphic adenomas. Out of 19 cases of pleomorphic adenomas diagnosed by cytology, 17 cases were confirmed by histopathology. Remaining two cases revealed different diagnosis. In three cases of pleomorphic adenomas diagnosed by histopathology, the cytology revealed different diagnosis. In six cases of tumours other than pleomorphic adenoma there was agreement between cytological and histological diagnosis. The diagnostic sensitivity, specificity and accuracy of preoperative FNAC of pleomor phic adenoma were 85%, 75% and 82.1% respectively. The Positive Predictive Value (PPV) and Negative Predictive Value (NPV) of FNAC were 89.5% and 66.7% respectively. Conclusion: Fine needle aspiration cytology is a useful preoperative diagnostic tool in evaluating Pleomorphic adenoma of salivary gland.

Objective. Clinical-neurophysiological and neuropsychological examination of patients with bruxism was conducted to determine the functional condition of the peripheral and central trigeminal nerve and to justify the combined therapy.Materials and methods. 26 patients (14 women and 12 men) aged 20 to 50 years with complaints and typical neurological symptoms of bruxism were examined. The control group consisted of 30 volunteers in the age from 24 to 35 years, who underwent a comprehensive examination as part of a medical check-up, who did not have severe somatic, neurological or mental diseases and did not have complaints of impaired function of the masticatory muscles. Clinical and neurological, electrophysiological and neuropsychological diagnostic methods were used in the trial. Quantitative sensory testing was performed using TSA II device (Medoc, Israel), and temperature sensitivity thresholds were determined using the Marstok method on symmetrical facial areas according to the Zelder zones. Diagnostics of the functional condition of the masticatory muscles was carried out using a computer neuroelectromyograph M-Test ‘DX-Systems’ and a computer system for analyzingelectromyographic records. Electroencephalography (EEG) was performed using 16-channel computer electroencephalography system. C. D. Spielberger scale adapted by Yu. L. Khanin (C. D. Spielberger, 2010) was used to determine the level of anxiety. The results were processed using Statistica and Microsoft Excel 2015 programs.Results. Patients with bruxism had a high level of personal anxiety, which was found in 73 % of the participants. Determination of the thresholds of cold sensitivity on the faces of patients with bruxism showed a lower threshold of cold sensitivity in the lateral parts and a higher threshold in the oral parts. Electromyography of masticatory muscles showed an increase in the duration of mastication period, a decrease in the masticatory rhythm, a decrease in masticatory efficiency, and irrational functioning of the masticatory muscles of varying severity in the patients of the examined group. Assessment of brain biopotentials showed an increase in the ascending activating effects of nonspecific median brain structures (72 %). The data obtained helped to obtain a comprehensive assessment of functional condition of the trigeminal nerve in patients with bruxism and to justify pharmaceutical therapy aimed at both the muscular apparatus (muscle relaxants) and the peripheral and central parts of the trigeminal nerve (antiepileptic drugs) in combination with a medicine that has a stabilizing effect on the functional condition of neurons and normalization of bioelectric processes in the central nervous system (correctors of metabolism).
