Dalam mempelajari matematika siswa sering kali merasakan kegelisahan, kekhawatiran, keprihatinan dan rasa takut. Sehingga dari perasaan tersebut muncul rasa cemas siswa dalam pelajaran matematika. Kecemasan dalam pembelajaran matematika adalah salah satu masalah yang mempengaruhi pembelajaran sehingga harus diminimalkan atau bahkan dihilangkan. Salah satu alternatif yang dapat mengurangi kecemasan siswa terhadap pembelajaran matematika adalah dengan penerapan model pembelajaran Kooperatif tipe Rotating Trio Exchange (RTE). Tujuan dari penelitian ini adalah untuk mengetahui apakah dengan penerapan model pembelajaran RTE dapat mengurangi tingkat kecemasan matematika. Pada penelitian ini, peneliti menggunakan pendekatan kuantitatif. Desain penelitian ini kuasi eksperimen kelompok kontrol tak setara (non equivalent control group desain). Subjek penelitian ini adalah siswa kelas VII-4 yang terdiri 31 orang dan kelas VII-2 yang terdiri dari 29 orang. Data dikumpulkan melalui pengukuran angket kecemasan matematika dan observasi. Berdasarkan hasil pengolahan data diperoleh bahwa tingkat kecemasan matematika siswa sebelum dan setelah penerapan model pembelajaran Kooperatif tipe RTE mengalami penurunan. Sebelum penerapan model RTE jumlah siswa yang mengalami sangat cemas 2 orang dan setelah penerapan siswa yang mengalami sangat cemas tidak ada lagi. Siswa yang mengalami cemas sebelum penerapan 15 orang dan setelah penerapan menjadi 4 orang. Siswa yang mengalami kecemasan sedang sebelum penerapan 8 0rang setelah penerapan menjadi 16 orang. Siswa yang tidak cemas sebelum penerapan 6 orang dan setelah penerapan menjadi 11 orang. Dari hasil penelitian digunakanlah statistik uji-t pihak kiri dengan taraf signifikan 5%. Dari hasil pengolahan tersebut dapat disimpulkan bahwa tingkat kecemasan matematika siswa yang diajarkan melalui penerapan model pembelajaran Kooperatif tipe RTE lebeih rendah dari tingkat kecemasan matematika siswa melalui pembelajaran konvensional.

Objective: Mycosis fungoides is the most common type of primary cutaneous T-cell lymphomas. In this study, we aimed to investigate the biochemical parameters of beta-2 microglobulin, lactate dehydrogenase, CD4/CD8 lymphocyte ratio determined by flow cytometry, and T cell clonality in patients with MF and to correlate these parameters in stage 1A and other stages.
Materials and Methods: A hundred sixty-one (87 Male, 74 Female) patients followed-up between January 1995 and January 2019 were retrospectively evaluated. Patients’ demographics, stage of the disease, peripheral lymph node and organ involvement, peripheral blood beta-2-microglobulin, lactate dehydrogenase levels, CD4/CD8 + lymphocyte ratio and presence of T cell clonality in biopsy samples were evaluated.
Results: Median beta-2 microglobulin levels were 1608.5 ng/ml for stage 1A and 1970.5 ng/ml for other stages. Peripheral blood median CD4/CD8 lymphocte ratio was 1.60 for stage 1A and 1.85 for other stages. We found statistically significant difference between two groups in terms of beta-2 microglobulin levels and peripheral blood median CD4/CD8 lymphocte ratio (p=0.001, p=0.04). No statistically significant difference was found between two groups in terms of lactate dehydrogenase levels and T-cell clonality (p=0.234, p=0.525).
Conclusion: Our study supports that high peripheral blood beta-2 microglobulin level and CD4/CD8 lymphocyte ratio at the time of diagnosis may imply advanced stage and poor prognosis in Mycosis Fungoides.

Published: December 2020

Objective: We aimed to evaluate our patient’s treatment responses to three-month immunotherapy for allergic rhinitis with or without asthma, and to investigate the factors affecting treatment
Material and Methods: A total of 53 patients receiving subcutaneous immunotherapy for allergic rhinitis with or without asthma were included in the study. All patients were positive for mite skin prick test. Asthma was present as a concomitant disease in 28(52.8%) patients. Patients with and without asthma were classified in two groups as “Allergic rhinitis + Asthma+” and “Allergic rhinitis+ Asthma-“. The values of pulmonary function tests of all patients, and in rhinitis with asthma patients, the Asthma Control Test scores before and after three months of treatment were recorded.
Results: In “Allergic rhinitis + Asthma+” and “Allergic rhinitis + Asthma-“groups, male/female ratio was 7/21 and 10/15, mean age was 33±9 and 32±9 years. No statistically significant differences were present between the pre-treatment and 3-month-treatment values of pulmonary function test. The difference between the pre-treatment and 3-month treatment asthma control test scores was strongly significant.
Conclusion: In allergic rhinitis, which is quite commonly associated with asthma, the control of asthma is also provided with the treatment of allergic rhinitis. By using pulmonary function test in allergic rhinitis and asthma control test in asthma, we showed that the effectiveness of allergen specific immunotherapy started in 3 months which was earlier from current literature.

Pasar modal dijadikan sebagai suatu pilihan pengganti sumber pendanaan untuk suatu perusahaan, serta sarana berinvestasi bagi investor. Instrumen yang diperjual-belikan di pasar modal berupa efek yang dapat diperdagangkan kembali oleh pemiliknya dalam bentuk saham atau diwujudkan dalam bentuk obligasi. Pada prinsipnya, instrumen yang terdapat di pasar modal bentuknya beraneka ragam, karena semua efek atau surat berharga dapat diperjual-belikan. Untuk instrument di pasar modal syariah yang boleh diperjual-belikan hanya apabila memenuhi prinsip syariah. Instrumen dalam pasar modal syariah dapat berbentuk saham syariah, obligasi syariah, reksadana syariah dan efek beragun aset (EBA) syariah.
Mekanisme transaksi penjualan dan pembelian saham yang dilakukan pada pasar modal syariah tidak boleh dilakukan secara langsung, hal ini untuk menghindari para spekulan untuk mempermainkan harga. Dalam proses perdagangan saham, aktivitas jual-beli tidak dilakukan secara langsung, melainkan pihak yang melakukan penawaran umum memberikan kekuasaan dan keleluasaan kepada agen di lantai bursa yang bertugas untuk mempertemukan perusahaan dengan calon investor. Saham tersebut kemudian diperjual-belikan karena tersedia dan berdasarkan pada prinsip first come-first served.
A REVIEW OF PENETRATION TUNGSTEN BASED PROJECTILE ON DEPTH OF PENETRATION AT ARMOR OF CERAMIC BASED

Published: December 2020

<p>Nowadays, tungsten-based material is used for the core of projectile, while ceramic-based is used for the main material of armor. Tungsten-based material is chosen because it has density and hardness superior to steel based-material. Meanwhile, the ceramic-based can enhance mobility and resistance penetration of armor. Penetration of projectile on target generates an impact velocity parameter. This velocity has resulted when the projectile hits the target. Therefore, the value of impact velocity affects the quantity of depth of penetration (DoP) result. This paper reviews some papers regarding the penetration of tungsten-based projectile on ceramic-based armor. Furthermore, the content of these papers is reviewed by the narrative review method, and the impact velocity and DoP are the main data to analyze. Through this paper, impact velocity has a linear correlation with the DoP, the big of impact velocity produced bigger of DoP, and vice versa. Based on the data in this review, for the same impact velocity, material, and (almost) dimension of a projectile, SiC has better penetration resistance than B4C, TiB2, and Al2O3. Furthermore, the parameter of projectile dimension, projectile material type, target design, and material composition of the target also affects the DoP result.</p>

Published: December 2020

Introduction:Early shared reading experiences positively predict outcomes in language andliteracy development of children who experience rich communicative and affective interactionsby parents during story narration. However, research is yet to be systematically exploremother’s practices and perceptions towards story narration and how employment of mothermay influence their perspectives and practices
Aim:Toanalyse the perspectives of employedand unemployed mothers of typically developing children between 2 to 5 years towards story narration.
Materials and Methods: The study followed a cross sectional design. A total of 60participants were selected in three age groups (Group I, II & III) of employed and unemployedmothers. A questionnaire was developed to analyse perceptions and practices of mother oftypically developing children between 2 to 5 years towards story narration. The responses werescored and analysed using SPSS Software, where a Chi-Square Test was performed to checkthe association.
Results:Chi-square analysis revealed no significant association of employmentin maternal perceptions towards story narration activities.
Conclusion:The study revealed thatemployment does not influence maternal perceptions towards story narration. The increase inmean score with age indicated a positive change in mother’s perception. This finding is animportant contributing factor to understand the role of mothers in children’s developing languageand early literacy skills. The study emphasises and highlights the lacuna in early interaction ofmothers in pre-literacy based activities, which can contribute to better academic performancein later stages.

Background: Medial prefrontal cortex (mPFC) is considered to be involved in human cognition to mPFCin terms of learning and memory. Hypoxia is one of the crucial factors causing secondary damage incerebral hemorrhage and traumatic brain injury. However, the underlying mechanisms and possibletherapeutic approach to prevent neuronal damage has not been attempted yet. Therefore, the present studyaimed to investigate the role of Tualang honey on medial prefrontal cortical neuronal morphology andcholinergic markers such as acetylcholine (ACh) and acetylcholinesterase (AChE) following exposure to normobaric hypoxia in rats.
Material and methods: Adult male Sprague-Dawley rats were dividedinto four groups: (i) sucrose treated non-hypoxia, (ii) sucrose treated hypoxia, (iii) Tualang honeytreated non-hypoxia and (iv)Tualang honey treated hypoxia. Rats received sucrose (1 mL of 7.9%) andTualang honey (0.2 g/kg), respectively, for 2 weeks prior to hypoxia exposure. Morphological study wasperformed by using Nissl staining and cholinergic markers were estimated by ELISA technique.
Resultsand discussion: Sucrose treated hypoxia group showed significantly lower mean ACh and higher meanAChE concentrations (P<0.05) compared to sucrose and honey treated non-hypoxia groups. Interestingly,mean ACh concentration was significantly increased and mean AChE concentration was significantlydecreased in Tualang honey treated hypoxic rats compared to sucrose treated hypoxic rats. Morphologicaldata showed that hypoxia caused neuronal damage in mPFC in sucrose treated hypoxia group whereasTualang honey treated hypoxia group significantly prevent neuronal damage.
Conclusion: Tualang honeyprotects hypoxia-induced mPFC neuronal damage through improvement of the brain cholinergic markersin male rats exposed to normobaric hypoxia.
