Published: December 2019

Artikel ini mendeskripsikan penerapan pembelajaran Kalkulus berbasis 4K (Kritis, Kreatif, Komunikatif, dan Kolaboratif) untuk meningkatkan kemampuan mahasiswa dalam memecahkan masalah matematika. Penelitian ini merupakan penelitian tindakan kelas. Subjek penelitian ini adalah mahasiswa program studi Pendidikan Matematika IKIP Budi Utomo Malang. Langkah-langkah pembelajaran berbasis 4K yang dapat meningkatkan kemampuan pemecahan masalah yaitu (1) mahasiswa diberikan permasalahan yang mendorong untuk berpikir kritis dan kreatif, (2) mereka diminta untuk berkolaborasi dan berkomunikasi dalam kelompok, (3) dilakukan kegiatan demonstrasi yang menuntut setiap mahasiswa berkomunikasi di hadapan teman sekelas, (4) mahasiswa diminta membuat permasalahan yang mendorong untuk berpikir kreatif. Berdasarkan hasil penelitian menunjukkan bahwa terdapat peningkatkan kemampuan mahasiswa dalam memecahkan masalah setelah diberikan pembelajaran berbasis 4K. Pada studi pendahuluan, sebagian besar mahasiswa mampu memahami masalah, namun hanya sedikit mahasiswa yang mampu membuat rencana dan melaksanakan rencana. Pada siklus I, untuk tahap memahami masalah sudah memenuhi kriteria penilaian yaitu lebih dari 70, tetapi untuk tahap yang lain masih kurang dari 70. Dikarenakan pada siklus I belum memenuhi kriteria keberhasilan, dilakukanlah siklus II. Sesuai dengan hasil penelitian siklus II diperoleh informasi bahwa skor rata-rata untuk setiap tahapan pemecahan masalah telah memenuhi kriteria lebih dari 70 yaitu dengan rincian untuk tahapan memahami masalah 88, membuat rencana 80, melaksanakan rencana 76, dan memeriksa kembali 75. Dengan demikian pembelajaran 4K dapat meningkatkan kemampuan pemecahan masalah mahasiswa.
Quarto de Despejo de Carolina Maria de Jesus: testemunho de uma existência condenada.
Authors: Santos Gustavo Alvarenga Oliveira 
Published: December 2019

Esse artigo tem como objetivo demonstrar que a obra Quarto de Despejo é um testemunho de uma existência condenada. Em um primeiro momento explica-se o que vem a ser a existência condenada a partir de uma crítica decolonial à ontologia fenomenológico-existencial de Heidegger e Sartre. Para tanto, recorre-se a autores do chamado pensamento decolonial latino-americano que adotam uma perspectiva de análise ontológica, mas ao mesmo tempo crítica ao eurocentrismo tradicional. Em um segundo momento, demonstra-se a articulação da narrativa de Carolina Maria de Jesus na obra Quarto de Despejo e a existência condenada conforme trabalhado na sessão anterior. Conclui-se que a fenomenologia-existencial, desde que descolonizada, pode contribuir para um melhor entendimento do mundo popular e subalterno latinoamericano que tem como traço característico e distinto à Europa a vivência da opressão pela via étnico-racial.

Notifikasi Aksi Korporasi Sebagai Instrumen Hukum Pencegah Praktik Monopoli dan Persaingan Usaha Tidak Sehat
Authors: Manalu Hottua 
Published: December 2019

This article discusses about corporation action notification on the competition law perspective. Corporation action notification is a notification obligations by the business actor to the Business Competition Supervisory Commision about corporation action in the form of incorporation, fusion, or company share acquition that caused asset value or sales value is ecxceed specific value. This article concluded that notification is an important instrument to prevent monopolistic practices and unfair competition, because a corporation action has an influence towards business competition, that can increase market concentration and this can make a product price more higher and business actor’s market power become bigger so that can threatening small business actor. However, the notification nowadays applied in Indonesia is notification to the commission after the corporation action has been done, or as known as post-notification, actually is not effective to prevent monopolistic practices and unfair competition, because of the notification is delivered after the corporation action has been done, so that in case the Commission assess that the corporation action is causing monopolistic practices and unfair competition then the revocation is complicated. Therefore, this article is encouraging notification to be done before corporation action is started, as known as pra-notification, so monopolistic practices and unfair competition possibility can be detected earlier and can be prevented.
Abstrak
Artikel ini membahas notifikasi aksi korporasi dalam perspektif hukum persaingan usaha. Notifikasi aksi korporasi adalah kewajiban pemberitahuan oleh pelaku usaha kepada Komisi Pengawas Persaingan Usaha atas aksi korporasi baik dalam bentuk penggabungan, peleburan, maupun pengambilalihan saham perseroan yang berakibat nilai aset dan atau nilai penjualannya melebihi jumlah tertentu. Artikel ini menyimpulkan, notifikasi merupakan instrumen penting dalam mencegah praktik monopoli dan persaingan usaha tidak sehat, dikarenakan aksi korporasi berpengaruh terhadap persaingan usaha, yaitu menyebabkan bertambahnya konsentrasi pasar yang dapat menyebabkan harga produk semakin tinggi dan kekuatan pasar pelaku usaha menjadi semakin besar sehingga dapat mengancam pebisnis kecil. Namun demikian, notifikasi yang saat ini berlaku di Indonesia, yaitu pemberitahuan kepada Komisi setelah aksi korporasi selesai dilakukan, atau yang dikenali dengan post-notifikasi, sesungguhnya tidak efektif mencegah praktik monopoli dan persaingan usaha tidak sehat, dikarenakan notifikasi disampaikan setelah aksi korporasi selesai dilakukan, sehingga dalam hal Komisi menilai aksi korporasi menyebabkan praktik monopoli dan persaingan usaha tidak sehat maka pembatalan jelas mengalami kerumitan. Oleh karenanya, artikel ini mendorong notifikasi dilakukan sebelum aksi korporasi dilakukan, yang disebut dengan pra-notifikasi, agar kemungkinan terjadinya praktik monopoli dan persaingan usaha tidak sehat diketahui sejak dini dan dapat dicegah.

Published: December 2019

This paper presents materials on the incidence of children with ixodiс tick-borne borreliosis in the Ulyanovsk region for the period 1996—2017.28 cases of tick-borne borreliosis among children were recorded. Tick suction in April-May was observed in 6 (21.4%) children, in June—August — in 12 (42.9%), in September—November — in 10 (35.7%). Migratory erythema was detected in 15 patients (53.6%). In half of the cases, moderate intoxication symptoms were observed (57.1%). Borreliosis was confirmed laboratory early in 75% of cases.Thus, a feature of ixodiс tick-borne borreliosis in children in the Ulyanovsk region is: detection of the disease during the period of tick activity, that is, in the early stages; equal ratio of erythema and non-erythhema forms; the prevalence in the clinic of mild symptoms of intoxication; laboratory confirmation in 75% of cases in the early stages. The presence of migratory erythema in the patient gives reason for the diagnosis of ixodiс tick-borne borreliosis even in the absence of positive results of a serological examination.

Anti-NMDA receptor encephalitis is an autoimmune disease of the central nervous system caused by autoantibodies to the NR1 and NR2 subunits of the glutamate NMDA receptor, with the possibility of both death and rapid remission. The binding of these antibodies blocks receptors and causes slowly developing psychiatric disorders, motor disorders and seizures.Presented clinical observation in a 9-year-old patient. The disease debuted with prodromal flu-like symptoms, fever, headache and general weakness, after which neuropsychiatric symptoms, impaired memory and speech developed, further progression of the disease, convulsive status, and coma with a fatal outcome were noted. The final diagnosis of autoimmune encephalitis was made after identification of antibodies to the N-methyl-D-aspartate (NMDA) receptor in the blood.

Published: December 2019

The sporadic incidence of tetanus, the identity of symptoms with the clinical picture of a number of common neuroinfections, the high frequency of various background pathologies create difficulties in disease diagnosing in children. On the case history example of a 3 years 9 months old child with two diseases (tetanus, enterovirus infection) that developed against the background of the active form of herpesvirus infection, an algorithm of diagnostic and therapeutic measures is presented.A differential diagnosis was made between the generalized form of tetanus and meningoencephalitis of enteroviral etiology. Lack of vaccination, living in rural areas, violation of the integrity of the skin and soil contamination testified in favor of tetanus. The clinical symptoms of tetanus were revealed: a triad of symptoms (trismus, «sardonic smile», dysphagia), tetanic cramps against a background of clear consciousness, muscle hypertonicity in the interictal period. The patient received complex treatment; 100 thousand IU of anti-tetanus serum and tetanus anatoxin were introduced. Discharged on the 23rd day of illness with recovery.
Too Big to Comprehend? A Research Note on How Large Number Disclosure Format Affects Voter Support for Government Spending Bills
Authors: Saiewitz Aaron , Piercey M. David 
Published: December 2019

ABSTRACT
Prior research suggests individuals have difficulty comprehending large magnitude numbers commonly associated with government spending (e.g., millions and billions). We conduct an experiment investigating how the disclosure format of large numbers in government spending affects voter support. We find participants' support for proposed government spending is insensitive to cost when presented in total (e.g., “$718 billion” versus “718 million”) but becomes cost-sensitive in response to a practical intervention, disclosing the dollar amounts in more understandable per-household terms (e.g., “$5,744 per U.S. household” versus “5.74 per U.S. household”), and find participant support becomes cost-sensitive after viewing this disclosure format. This research demonstrates how support for government spending can change significantly depending on different (but economically equivalent) disclosure formats. Specifically, the per-household disclosure format increases stakeholders' understanding of large magnitude spending policies and helps them form judgments better informed by their cost-sensitive preferences.

Published: December 2019

In this study, the gas sensing properties of SnO2
and Zn0.50Sn0.50O samples produced by Succession Ionic Layer
Adsorption and Reaction (SILAR) method with different SILAR cycles against NO gas were
investigated. Electrical characterization of the produced sample at different
temperatures (35 °C-135 °C) and different gas concentrations (50 ppb-25 ppm)
were performed. The working temperature was found at 105 °C. The sensors were proved to have acceptable responses towards 50 ppb NO
gas. Zn0.50Sn0.50O sensor exhibited improved sensing
performance at working temperature of 105 °C compared to SnO2 sensor.. The ,responses of SnO2 sensors
for the 50 ppb NO gas concentration, sensitivities of 1.74%, 2.15% and 3.37%
were obtained for 20, 30 and 40 cycles, respectively. On the other hand,
the,responses of Zn0.50Sn0.50O sensors for the 50 ppb NO
gas concentration sensitivities of 3.01%, 3.74% and 4.16% were obtained for 20, 30 and 40
cycles, respectively. The measurement results showed that the sensitivity of
the sensors changed depending on the doping and producing cycles.
La descolonización del derecho y la justicia comunitaria em el marco del nuevo constitucionalismo latinoamericano
Authors: Ricobom Gisele , Friggeri Félix Pablo 
Published: December 2019

El trabajo aborda una de las categorías teóricas más ricas y dinámicas sobre la estructuración injusta de la realidad latinoamericana es aquella revelada por la colonialidad del poder y del saber, no solo como una perspectiva de análisis del pasado, sino sobre todo como una reflexión permanente y actual que posee una extrema capacidad de penetración en todas las camadas sociales de América Latina. Los estudios descoloniales permitirán visibilizar los mecanismos coloniales arraigados en las estructuras institucionales del Estado y de la sociedad latinoamericana. La emergencia de una sociología decolonial contribuye vivamente para pensar y construir otra posibilidad de justicia, resultado de una legalidad subalterna que refunda el orden constitucional sobre bases profundamente innovadoras. Concluye sus autores que el proceso de descolonización es continuo, la justicia comunitaria es apenas una de sus estrategias más importantes, pero es una fuente preciosa e inmensa para repensar el derecho a partir de los valores populares, libertándolo de su atadura servil a la propiedad burguesa.
Microbiome and hypertension: where are we now?
Authors: Vallianou Natalia G. , Geladari Eleni , Kounatidis Dimitris 
Published: December 2019

Background
Hypertension is the leading risk factor for cardiovascular disease and accounts for approximately 9.4 million deaths globally every year. Hypertension is a complex entity, which is influenced by genetic and environmental factors, such as physical inactivity, obesity, alcohol consumption, tobacco use, stress, diet and why not the microbiome.

Methods
We searched PubMed using the words ‘microbiome’, ‘microbiota’ and ‘hypertension’ until December 2018. We found information regarding the role of the brain–gut--bone marrow axis, the brain–gut--kidney axis, the high-salt diet, short-chain fatty acids (SCFAs), neurotransitters, such as serotonin, dopamine and norepinephrine, nitric oxide, endothelin and steroids in modulating gut microbiota and in contributing to the pathogenesis of hypertension. The brain--gut--bone marrow axis refers to the hypothesis that hematopoietic stem cells might migrate to the brain or to the gut, and thus, contribute to local inflammation and several immune responses. This migration may further enhance the sympathetic activity and contribute to blood pressure elevation. On the other hand, SCFAs, such as acetate and butyrate, have been shown to exert anti-inflammatory effects on myeloid and intestinal epithelial cells. Also, researchers have noted diminution in microbial richness and diversity in hypertensive patients as well as marked differences in circulating inflammatory cells in hypertensive patients, when compared with controls. In addition, activation of renal sympathetic nerve activity might directly influence renal physiology, by altering body fluid balance and plasma metabolite secretion and retention. These events culminate in the development of chronic kidney disease and hypertension.

Conclusion
There is a long way ahead regarding the role of gut microbiota in the pathogenesis and as an adjunctive treatment of hypertension. Treatment of dysbiosis could be a useful therapeutic approach to add to traditional antihypertensive therapy. Manipulating gut microbiota using prebiotics and probiotics might prove a valuable tool to traditional antihypertensives.

Published: December 2019

Background
Twelve-lead ECG represents the most common diagnostic tool in clinical cardiology and allows an immediate screening of left ventricular hypertrophy (LVH), but current criteria might have poor clinical usefulness in everyday clinical practice due to lack of sensitivity.

Methods
The current study aims to review and compare the clinical performance of known ECG criteria of LVH in a real-life setting; 2134 patients had ECG and echocardiographic exams performed during the same hospitalization. All traces were retrospectively analysed, and the amplitudes of the waves were manually measured. Transthoracic echocardiography was considered as the gold standard to assess LVH.

Results
LVH had a prevalence of 58%. Considering the diagnostic performance of ECG criteria for LVH, the Cornell voltage carried the best area under the receiver operating characteristic curve (0.678), while RaVF (R wave in aVF lead) had the poorer result (0.440). The R5/R6 criterion had the best sensitivity (60%), but with the worst specificity (37.4%). The ‘Q or S aVR’ had the best specificity (99.9%) but lacks sensitivity (0.80%). The Peguero Lo Presti criterion had a sensitivity of 42.3% and a specificity of 75.8%. The Cornell voltage and the Cornell product had similar area under the receiver operating characteristic curve values which were found to be significantly greater compared with other criteria.

Conclusion
Current ECG criteria of LVH have low sensitivity despite an acceptable specificity. Among these, Cornell voltage and Cornell product criteria were equally found to have a more accurate diagnostic performance compared with other criteria. To overcome the intrinsic limitations of the current ECG LVH criteria, a new paradigm in the analysis of electrocardiographic data might be necessary.
