CONFORMAL PREDICTION USAGE FOR THE ACUTE PANCREATITIS OUTCOMES FORECAST
Authors: Чеботарь Антон Викторович , Гальченко Максим Иванович
Published: April 2021

Конформное прогнозирование и его частный случай Мондриановская конформная классификация является новым методом, позволяющим повысить валидность результатов. Конформное прогнозирование удобно в применении и позволяет использовать большинство алгоритмов машинного обучения. Одним из отличий от классических методов является то, что алгоритм конформного прогнозирования позволяет использовать скошенные выборки без предварительной корректировки. В работе рассматривается возможность применения данного метода к задаче прогнозирования течения острого панкреатита на небольшой выборке (91 запись). Рассматривается возможность прогнозирования возникновения инфекционного осложнения и летального исхода. Используется реализация метода в KNIME Analytics Platform, выполненная компанией Redfield AB, Швеция, показывается порядок применения узлов, описываются критерии качества для конформной классификации (эффективность и валидность). Результат позволяет говорить о хороших показателях при применении метода в условиях скошенности классов, в случае прогнозирования исхода, без предварительной корректировки выборки и возможности его применения к небольшим выборкам. Для прогноза исхода эффективность составила 0.67 для класса «Выжил» и 0.14 для класса «Летальный исход», валидность составила 1 и 0.86 соответственно, для прогноза инфекционных осложнений эффективность составила 0.86 для класса «Нет инфекционных осложнений» и 0.43 для «Инфекционные осложнения», валидность 0.71 и о.79 соответственно

Conformal prediction and its special case Mondrian conformal classification is a new method that can improve the validity of results significantly. One of the interesting differences from the classical methods is that the conformal prediction algorithm allows using skewed samples without preliminary preprocessing. Possibility of applying this method to the problem of predicting the outcomes of acute pancreatitis on a small sample is studied in the paper (91 records). The implementation of the method in the KNIME Analytics Platform, made by Redfield AB, Sweden, is used, the order of the nodes usage is shown, the quality criteria for the conformal classification (efficiency and validity) are described. The results are allowed to say about good results of applying the method on the sample with skewed classes without preliminary adjusting the sample and the possibility of applying it to small samples. For the “Outcome” variable, the effectiveness was 0.67 for the class "Survived" and 0.14 for the class "Fatal outcome", the validity was 1 and 0.86, respectively, for the prognosis of infectious complications, the effectiveness was 0.86 for the class "No infectious complications" and 0.43 for the class "Infectious complications", validity 0.71 and o.79, respectively

US Employment Inequality in the Great Recession and the COVID-19 Pandemic
Authors:   Washington University in St. Louis, Fazzari Steven , Needler Ella
Published: April 2021

This article compares inequality in US employment across social groups in the Great Recession and the COVID-19 pandemic. We develop an inequality measure that captures both how much employment declines during a recession and the persistence of those declines. The results show a significant shift of job loss from men in the Great Recession to women in the COVID-19 lockdown. White workers fare better than other racial/ethnic groups in both recessions. Black and Hispanic women are hit especially hard in the COVID-19 pandemic. With our job loss measure, less educated workers had modestly worse outcomes in the Great Recession. However, during COVID-19, less educated workers suffer much more severe employment consequences than more educated groups. We discuss long-term effects of employment inequality and how these findings are relevant to debates about policy responses.

Published: April 2021

The background of this research is that God tells humanity to make their contribution to people in need. Wealth that must be managed and distributed to the community and wealth should not only be concentrated in certain groups. Wealth that is only centered on certain groups will hamper economic growth because this cannot be utilized as well as possible and eventually cause community opposition. According to the Islamic economic system, distribution is obtained through data sources obtained from Islamic economic system books, literature, and relevant study materials. Ownership in the concept of Islam, what is in the universe belongs only to Allah. Humans as a trusted caliph to be approved by the universe.

Published: April 2021

Rice, Market, Price and government intervention are a unified whole that cannot be separated. If the market is not stable it will affect the price. This paper aims to describe and explain why controlling rice prices needs to be done by the government through the TTIC program in South Sumatra from the perspective of an Islamic economic perspective. study of the perspective of Islamic economics that recognizes free markets. Prices are submitted to the market where prices are formed at the request and supply so that a normal price is formed. The government is not allowed to intervene when prices are normal. The government is only justified in an emergency by promoting the concept of justice. The al-Hisbah institution functions as an independent institution that is free from the interests of certain groups. The intervention of the price of rice by the government aims to benefit the masses so that it does not overburden the community when the price of rice surges. This government program is carried out to keep prices stable when market demand increases. This type of research is field research conducted using a qualitative approach, this study departs from the conditions in the field in order to see and understand the phenomena that exist and are reversed in more depth. Symptoms include the views, thoughts, attitudes and actions of the informants, and also include the situations and conditions observed as well as the data which are the Sumatran TTI Center documents. The results of this study indicate that the government has carried out its role as a state institution that functions to control prices when prices rise in the community.

Published: April 2021

Zakat merupakan instrumen khas dalam agama Islam. Sebagaimana eksistensi perintah zakat dalam al-Qur’an yang mayoritas beriringan dengan perintah menegakkan shalat. Di samping berdimensi ibadah mahdah yang bersifat vertical, zakat sangat kental dengan dimensi sosial yang terasa horizontal. Dimensi sosial itu tampak nyata bahwa zakat diwajibkan seorang muslim yang dikategorikan berkecukupan hartanya untuk didistribusikan kepada orang lain yang masuk kategori mustahiq zakat. Pada tahun 2013 jumlah layanan pada program RMB awalnya hanya berjumlah 2.968 warga binaan, pada awal tahun 2014 meningkat menjadi 9.374 warga binaan, dan tidak menutup kemungkinan pada tahun 2015 akan jauh lebih meningkat lagi

Using the degree theory, we give some surjectivity results for operators of generalized monotone type in reflexive Banach spaces. In the Hilbert space case, this reduces to the celebrated Browder-Minty theorem for monotone operators.

The purpose of this article is to investigate a projection algorithm for solving a fixed point problem of a closed multi-valued Bregman quasi-strict pseudocontraction and an equilibrium problem of a bifunction. Strong convergence of the projection algorithm is obtained without any compact assumption in a reflexive Banach space. As applications, monotone variational inequality problems are considered. Finally, a numerical simulation example is presented for demonstrating the feasibility and convergence of the algorithm proposed in main result.

In this paper we present two new results for the existence of fixed points of multivalued mappings with closed values on quasi metric space. First we introduce the multivalued Fd-contraction on quasi metric space (X, d) and give a fixed point result related to this concept. Then taking into account the Q-function on a quasi metric space, we establish a Q-function version of this concept as multivalued Fq-contraction and hence we present a fixed point result to see the effect of Q-function to existence of fixed point of multivalued mappings on quasi metric space.

Steganography is a method of hiding secret information into an innocent looking container. Although a large number of steganography techniques have been proposed, there is a constant need for new variants because they have a relatively short lifespan, being defeated by steganalysis techniques. This article explores the possibilities of eliminating the main drawback of LSB steganography: weakness. The problem is solved by rearranging the image pixels and by applying a compensation technique that preserves their statistical properties. The proposed method contains an encryption block that adds an extra layer of security to the hidden data

First, we establish approximation in a Lipschitz type space and weighted approximation theorems for these operators. Then we obtain a Voronovskaja type result and the rate of convergence in terms of the weighted modulus of continuity.

The transformation processes taking place in the economic and social spheres of society determine, on the one hand, the prospects for economic growth, and on the other, the prerequisites for the emergence of new risks associated with the environmental and social security of states and individual territories. Therefore, we believe that in the current conditions of socio-economic development of both individual territories and socio-economic spaces as a whole, one of the main imperatives for the economic growth of territorial systems should be considered the influence of the environmental factor that determines the possibility of full-fledged life activity of society taking into account the preservation and development of the gene pool of the nation and the rational use of natural resources.

Tyrimo tikslas. Įvertinti neinvazinius tyrimus kaip alternatyvą biopsijai, nustatant kepenų fibrozę ir vertinant atsaką į gydymą. Tyrimo metodai. Nuo 2020 m. gruodžio mėn. iki 2021 m. vasario mėn. atrinktos mokslinės publikacijos iš „PubMed“ duomenų bazės pagal reikšminius žodžius, remiantis įtraukimo ir neįtraukimo į tyrimą kriterijais. Rezultatai. Magnetinio rezonanso elastografija (MRE) yra jautresnė vertinant kepenų fibrozę ir cirozę nei magnetinio rezonanso tyrimas (MRT). MRE, neinvazinė vibracijos kontroliuojama trumpalaikė elastografija (angl. vibration-controlled transient elastography (VCTE)) ir 2D skersinės bangos elastografija (angl. 2D shear wave elastography (2D-SWE)) tikslūs diagnozuojant kepenų fibrozę pacientams, sergantiems nealkoholiniu kepenų suriebėjimu. Realaus laiko elastografija (angl. real time elastography (RTE)) leidžia nustatyti pažengusią fibrozę, o VCTE tiksliai nustato tiek ankstyvą, tiek pažengusią fibrozę. Kompiuterinės tomografijos (KT) tyrimas yra gana reikšmingas kepenų fibrozei diagnozuoti ir gydymo atsakui įvertinti. Išvados. Šie neinvaziniai tyrimai gali būti kaip alternatyva plačiai taikomai kepenų biopsijai.

Auto-brewery sindromas arba alkoholio fermentacijos žarnyne sindromas yra reta medicininė būklė, kuri pasižymi endogenine alkoholio gamyba. Šis sindromas gali sukelti tuos pačius fizinius ir psichologinius simptomus, kurie pasireiškia, kai žmogus yra neblaivus arba pagiringas. Patogenezė siejama su virškinamojo trakto grybeline disbioze, kai alkoholį fermentuojančios mielės suvartotus angliavandenius paverčia etanoliu. Paprastai liga pasireiškia intoksikacijos nuo alkoholio požymiais, tačiau ankstyviausi simptomai gali būti nuotaikos pokyčiai, kliedesys arba smegenų rūkas. Diagnostikai svarbu angliavandenių provokavimo testas bei viršutinė ir apatinė endoskopija su mėginiais kultūrai ir jautrumui nustatyti. Tai būklė, kurią galima gydyti pakeitus mitybą, taikant tinkamą priešgrybelinį gydymą ir galbūt probiotikus.

Adolescence is a period associated with increased risk behaviors such as smoking, sex, fighting, the use ofsharp weapons and so on. These conditions coincide with changes in social and school environment. Thepurpose of this study is to explain how health risk behaviors are to adolescents. The research design usedin this study was analytic with a cross sectional approach. The population was all high school/vocationalschool adolescents with a total of 29,963 boys and girls, with a sample size of 395 using cluster samplingtechnique. The independent variable of the study is risk behavior and the dependent variables of the studyare smoking, bullying, use of sharp weapons, driving, drug consumption, sex, health consultation, nutritionalfulfillment, suicide attempt, alcohol consumption, fighting and physical activity. Data collection was carriedout using a questionnaire adopted from YRBSS (Youth Risk Behavior Surveillance System) which wastranslated into Indonesian. The collected data was tabulated and analyzed using Logistic Regression. Theresults showed that all health behavior including risk behaviors, although based on statistical test resultsthe behavior of alcohol and drug consumption was not significant because (p value) was 0.000>0.005.Smoking behavior had a regression coefficient of 6,904 with a significance level (p value) of 0.000<0.005and an OR (odds ratio) of 996,365, which means that adolescents have 996 times the chance to smoke. Allvariables are included in health risk behaviors; however, smoking is the riskiest health behavior carried outby adolescents

Background: Cataract is the clouding of lens which subsequently may impair vision. The main subtypesof senile cataract are cortical, posterior sub-capsular and nuclear sclerosis. Electrolyte disturbance has beenlinked with the development of age related cataract.Aim of the Study: To assess the correlations between the levels of the blood biochemical elements (Ca++,Na+, K+, Cl-) and the formation of senile cataract.Patients & Method: Blood samples of 35 patients of cataract and 35 of non-cataract/ healthy people havebeen analyzed for calcium and electrolytes levels, all cases were female whose age ranged between (50– 70 years). (5 mL) of blood was taken from the patients’ veins for the study. The serum was separatedof each sample by a centrifuge at (4000) rpm for (4 min) and used for the mentioned biochemical exams.(FUJIFILM/ DRI-CHEM NX500i) biochemical analyzer was utilized in the study. The results were obtaineddirectly from the analyzer.Results: In cataract patients group, there was a significant variations in calcium level (high, normal, andlow) as well as sodium level (low and normal) compared to the control. There was no significant differencesin the level of (K+ and Cl-) between two groups.Conclusion: In the current study, there was a significant differences in calcium and sodium level in cataractpatients group compared to the control. These variations might be one of many factors that contribute in theformation of cataract.

Progress in regenerative endodontic procedures needs approval by clinicians, but there is little or noevidence. This study aimed to examine the awareness, mindset and experience of regenerative endodonticsamong Indian dental residents. For the survey they used a self-administered questionnaire which consistedof three parts; part A focused on the background and experience of dentists, part B pursued the viewpoint,views and decision of the dentist about the utilize of PRF and Regenerative techniques, Whereas part Ccontained questions focused on their clinical experience. Findings indicate that maximum respondents knewabout PRF during postgraduate training but 90% are willing to attend PRF and REP training. However,few claimed to have used any form of regenerative therapy in their work. Finally, it can be concludedthat findings are an indication of optimistic dental residents concerning the use of regenerative endodonticmethods; however, further analysis and routine training is needed.
