OPTIMASI ALGORITMA C4.5 MENGGUNAKAN METODE FORWARD SELECTION DAN STRATIFIED SAMPLING UNTUK PREDIKSI KELAYAKAN KREDIT
Authors: Ubaedi Ibnu , Djaksana Yan Mitha 
Published: March 2022

Kredit merupakan dana yang diberikan oleh bank kepada pihak lain berdasarkan perjanjian pinjam-meminjam, yang mewajibkan peminjam melunasi pinjamannya setelah jangka waktu tertentu. Sebelum memberi kredit, bank perlu menganalisis kemampuan nasabah dalam melunasi utangnya untuk mengurangi resiko kredit. Analisis kredit yang dilakukan oleh bank terkadang tidak akurat, sehingga menimbulkan kredit macet. Masalah ini akan diselesaikan dengan memanfaatkan teknologi data mining, yaitu membuat pohon keputusan menggunakan algoritma C4.5 untuk memprediksi kelayakan kredit. Tetapi, algoritma C4.5 memiliki masalah penurunan akurasi ketika dihadapkan dengan atribut dan jumlah data yang besar. Masalah ini akan diselesaikan dengan metode Feature Selection dan Stratified Sampling yang terbukti dapat menyelesaikan masalah atribut dan jumlah data yang besar. Hasil penelitian menunjukkan bahwa pohon keputusan yang dihasilkan dari algoritma C4.5 memiliki akurasi cukup baik sebesar 79,11% dan metode Feature Selection dan Stratified Sampling berhasil meningkatkan akurasi algoritma C4.5 sebesar 9,2% dalam memprediksi kelayakan kredit.

Published: March 2022

This article is devoted to evaluating the efficacy of the use of succinic and formol-succinic biostimulant for the prevention and treatment of edematous disease and salmonellosis in piglets, namely, its influence on the infectious process and therapeutic effectiveness in these diseases. To assess the efficacy of edematous disease, we took five-day-old piglets, which were further divided into three groups: two groups for each drug and, accordingly, the third was a control. The case of salmonellosis was a spontaneous situation during the vaccination of piglets. All piglets were also divided into three groups, but selection was not chaotic as with edematous disease. The piglets were divided into groups only after a clinical examination into "sick", "suspicious" and "clinically healthy". The scheme of using drugs for salmonellosis was similar to that for edematous disease. It should be said the course of treatment with the use of an succinic biostimulant in combination with gentamicin provided a favorable fracture of the disease after a single injection of drugs. All animals of this group had only residual symptoms of the disease on the second day. In fact, a similar pattern was observed when using a formol-succinic biostimulant, but still one piglet from this group fell.	In the situation with salmonellosis, the use of formol-succinic biostimulant on clinically healthy piglets during the outbreak was very successful. There are no cases of the disease were registered. In the group of piglets that were treated with one succinic biostimulant, 1 (4.5%) case of suspected salmonellosis was registered. The incidence of salmonellosis in the control group was 15%. It should be noted that the intensive therapy course, including a succinic biostimulant in combination with gentamicin, proved to be quite effective for the treatment of sick animals of the control group. In all piglets, clinical recovery was achieved after the first administration of the drugs. Thus, based on the results of the conducted experience, it was possible to draw the following conclusions: - the preventive use of succinic and formol-succinic biostimulants for piglets provides effective correction of immunometabolic processes, which is an important condition for increasing the body's resistance to pathogens of colibacteriosis and salmonellosis.

Published: March 2022

Alteration in the backbone structure of the endogenously released opioid peptides Leu5/Met5 enkephalins may result in compounds having comparable profile of pharmacological activity but with different physicochemical properties and side effects. Phthalyl amino acid and phthalyl esters are among the derivatives that have been synthesized and evaluated for their antibacterial and antifungal activities.This study was conducted to evaluate the possible analgesic activity of phthalyl-tyrosyl-glycin sodium that has been recently synthesized by our team.The study was carried out on 24 albino mice using hot plate method. The animals were allocated in to three groups; the first group received saline and represent a control group; the second group received morphine HCl as a standard drug; and the third group received phthalyl-tyrosyl-glycin sodium. The onset with which the animal lift his forearm and the number of jumps per 25 seconds were recorded for each group.
The results of this study showed that phthalyl-tyrosyl-glycin sodium resulted in significant improvement (P<0.05) in analgesia score as well as significant delay in the onset of induced hyperalgesia in comparison to saline-treated group, and in comparison to morphine HCl, no significant difference (P>0.05) was observed in analgesia score but with significant delay in induced hyperalgesia.The results obtained in this study provide experimental evidences for the effectiveness of the prepared compound as analgesic with comparable effect to that of morphine.

Entre a Experiência Religiosa e o Entretenimento: ressignificações da música gospel como atração no programa Esquenta!
Authors: De Oliveira Jênifer Rosa 
Published: March 2022

Esta pesquisa tem por objetivo analisar sob quais aspectos se dá a interação entre mídia e religião, bem como as tensões ou continuidades que a aproximação do ‘sagrado’ com o ‘profano’ na sociedade midiatizada evoca. Para tal, foram realizados dois grupos de discussão, um formado por pessoas evangélicas e outro formado por pessoas não-evangélicas, para analisar como as atrações gospel exibidas pelo programa Esquenta! – transmitido dominicalmente pela Rede Globo – são ressignificadas pela audiência. Interessou-nos compreender como os conteúdos religiosos deslocados de seu contexto original são reapropriados pelo público. Para efetuar nossa análise, tomamos como referencial teórico os conceitos de cultura gospel e de midiatização, especialmente o conceito de bios midiático, e a discussão sobre secularização proposta por Habermas.

OBJECTIVE
Female neurosurgeon representation has increased, but women still represent only 8.4% of neurosurgeons in the US. Women are significantly underrepresented as authors in neurosurgical and spine journals, a key indicator of professional success in academic medicine. In this study, the authors aimed to assess the gender diversity of first and last authors of accepted abstracts at neurosurgical conferences in 2015 and 2019.

METHODS
Annual meeting abstracts for 2015 and 2019 of the American Association of Neurological Surgeons (AANS), Congress of Neurological Surgeons (CNS), and pediatrics, spine, stereotactic and functional surgery, and cerebrovascular AANS/CNS subspecialty sections were obtained and analyzed for gender. Partial data were obtained for tumor and pain sections. Composite gender data were obtained from the societies. Percentage differences were calculated using comparison of proportions testing.

RESULTS
Overall, female neurosurgeons accounted for only 8.3% of first and 5.8% of last authors, and 7.2% of authors overall. The pediatrics section had the highest proportion of female neurosurgeons as first (13.7%) and last (12.4%) abstract authors, while the spine section had the lowest proportions of female neurosurgeon first (4.6%) and last (2.0%) authors. Qualitatively, a higher proportion of women were first authors, while a higher proportion of men were last authors. Overall, there was no significant change in female neurosurgeon authorship between 2015 and 2019. With regard to society demographics, female neurosurgeons accounted for only 6.3% of AANS membership. The pediatrics section had the highest proportion of female neurosurgeons at 18.1% and the stereotactic and functional surgery section had the lowest of the subspecialty sections (7.6%). While female neurosurgeons represented 12.6% of spine section membership, they represented only 4.7% of first authors (−7.9% difference; p < 0.0001) and 2.4% of last authors (−10.2% difference; p < 0.0001). For the 2019 cerebrovascular section, female neurosurgeons were underrepresented as presenting authors (5.8%) compared with their membership representation (14.8%, −9.0% difference; p = 0.0018).

CONCLUSIONS
Despite an increase in the number of female neurosurgeons, there has not been a corresponding increase in the proportion of female neurosurgeons as abstract authors at annual neurosurgery conferences, and female neurosurgeons remain underrepresented as authors compared with their male colleagues.
Features of grouping low-producing oil deposits in carbonate reservoirs for the rational use of resources within the Ural-Volga region
Authors: Mukhametshin Vyacheslav , Khakimzyanov Ilgizar 
Published: March 2022

A methodology has been developed and a procedure for selecting homogeneous groups has been implemented using a set of parameters characterizing the properties of formation fluids, layering conditions, geological and physical properties of formations at different levels of the hierarchy. An algorithm for identifying deposits for monitoring and justifying measures to improve the efficiency of development management is proposed. A justification for the selection of associative groups of long-term developed objects using the parameters of geological heterogeneity according to different tectonic-stratigraphic elements is presented. To reduce the degree of uncertainty in the evaluation of objects by the degree and nature of geological heterogeneity, the parameters reflecting the degree of uncertainty of the system using complex characteristics are proposed. For different deposit associations, a different influence of the features of the object structure on the degree of their division has been established. In the process of deposit drilling, as additional information about development objects is obtained, it is necessary to specify the nature of the distinguished groups of objects first of all based on the use of characteristics of geological heterogeneity. Comparison of various grouping options shows the need to take into account the geological heterogeneity of objects during their drilling. The identification of groups of objects using a limited number of parameters is approximate, but at the stage of drafting the first design documents, it is possible to solve certain tasks aimed at determining the strategy for the development of deposits

Relevance and methodology. The results of laboratory studies of solutions of disinfectants Penox-1 and Penox-2, carried out on rough tests surfaces made of concrete, wood and metlakh tiles, against Mycobacterium (strain B-5) and Bac. cereus spores (strain 96) are presented. Experiments were carried out to establish the modes of disinfection of Penox-2 in a comparative aspect with solutions of Penox-1. For protein protection of the test cultures, horse blood serum was applied to the test surface, at the rate of 0.5 g/100 cm2. When developing disinfection modes, contaminated rough test surfaces were placed horizontally and vertically. Disinfection of the test surfaces was carried out by the method of wet disinfection, at the rate of 0.5 l/m2, at exposure 1; 3 and 24 hours. The treatment was carried out twice with an interval of 60 min. All studies were carried out in 3-fold repetition. The criterion for the effectiveness of the agent in the disinfection of surfaces is 100% death of test cultures.Results. It was found that with a single irrigation with solutions of the Penox-1 preparation, disinfection of test surfaces made of concrete, wood and metlakh tiles contaminated with mycobacteria and Bac. cereus spores was not achieved. Disinfection of the test surfaces from mycobacteria occurred with double irrigation, exposure for 24 hours, at the rate of 1 l/m2. Double irrigation of Bac. cereus spores did not result in decontamination of test surfaces. At the same time, the addition of chloramine B to the composition of the preparation Penox-2 at a concentration of 0.5–3.0% led to the disinfection of test surfaces from mycobacteria and Bac. cereus spores respectively after 1 and 3 hours, at the rate of 0.5 l/m2, with single irrigation.

Published: March 2022

В статье представлен анализ процессов воспроизводства населения г. Элисты Республики Калмыкия 2007 г. Исследуется собранный репрезентативный популяционно-генетический материал с привлечением материалов переписей населения и других официальных статистических источников информации. В среднем в Элисте на каждую женщину пострепродуктивного возраста приходится 5.82 беременности, 2.15 рождений и 3.32 абортов. Исследование показало, что в городских семьях практикуется регулируемый тип рождаемости. Снижена пропорция спонтанных абортов, выкидышей и внематочных беременностей 0.28. Таким образом, только 37% всех беременностей завершилась родами; соответственно 57% беременностей искусственно прерывается. Применение метода J.F. Crow и его модификации позволили впервые количественно оценить вклад социальной компоненты в величину коэффициента отбора в популяции Элисты. Выявлено значительное возрастание вклада небиологических факторов в величину коэффициента максимально возможного потенциального отбора.
in English:
The article analyzes the processes of population reproduction in the city of Elista, the Republic of Kalmykia, in 2007. The collected representative population genetic material is investigated with the data from the All-Russia Census and other official statistical sources. On average, there are 5.82 pregnancies, 2.15 births and 3.32 abortions for every woman of post-reproductive age in Elista. The study demonstrates that birth control is practiced in urban families. The proportion of spontaneous abortions, miscarriages and ectopic pregnancies is as low as 0.28. Thus, only 37% of all pregnancies resulted in livebirth; accordingly 57% of pregnancies are terminated artificially. The contribution of the social component to the value of the natural selection coefficient in the population of Elista was calculated applying the method of J.F. Crow and its modifications. A significant increase in the contribution of non-biological factors to the value of the coefficient of the maximum possible potential selection was revealed.

Published: March 2022

Background: The use of rotating hinge (RH) prostheses for severe primary as well as revision arthroplasty is widely established. Due to the steadily increasing number of RH prostheses, we aimed to assess the complication frequencies, complication types and clinical outcomes of a modern RH hinge prosthesis using a new bearing material with a minimum follow-up of 7 years.Methods: Fifty-six consecutive patients who received the EnduRo® RH prosthesis using carbon-fiber reinforced poly-ether-ether-ketone (CFR-PEEK) as bearing material were included in this prospective study: 21 patients (37.5%) received the prosthesis as a primary total knee arthroplasty (TKA) and 35 patients (62.5%) underwent revision total knee arthroplasties (rTKA). Clinical and radiographic examinations were performed preoperatively, postoperatively after three and 12 months and annually thereafter. Clinical scores were documented for each patient. Competing risk analysis was assessed with respect to indication and failure mode.Results: Knee Society Score (KSS), Western Ontario and McMaster Osteoarthritis Index (WOMAC), Oxford Knee Score (OKS) and range of motion (ROM) improved significantly compared to preoperative values (p &lt; 0.0001). The overall cumulative incidence for revision surgery was 23.6% at 7 years and the cumulative incidence for complications associated with failure of the prothesis was 5.6% at 7 years, respectively. Complications occurred more frequently in the revision group (p = 0.002).Conclusion: The evaluated RH prosthesis provided reliable and durable results for a minimum follow-up of 7 years. Prosthesis survival was successful considering the complexity of the cases. The use of this RH system in primary patients showed high survival rates and long-term functional outcomes and clinical outcomes proved to be satisfying in both revision and primary cases. No adverse events were associated with the new bearing material CFR-PEEK.
