Published: February 2022

The purpose — to study the indicators of the main risk factors for sudden cardiac death in the acute period in patients with myocardial infarction without coronary artery obstruction (MIwCAO). Material and methods. We examined 60 patients admitted to the Republican Clinical and Diagnostic Center of the Ministry of Health of the Udmurt Republic with a diagnosis of myocardial infarction, 30 of whom had a single-vessel lesion of the coronary bed and 32 had a myocardial infarction without obstruction of the coronary arteries. Results. The main indices of intracardiac hemodynamics (LVEF, EDV) were worse in the group of patients with MIwCAO: LVEF was on average 5.2% lower, LV EDV was higher by 26 ml. Heart rate was higher in patients with MIwCAO both in the daytime and at night. Among the ventricular rhythm disorders (VRD) in the group of patients with MIwCAO, most frequent were single VES, unstable paroxysms of VT, and polymorphic ventricular premature beats. In the remote period of myocardial infarction, indicators of SCD risk improved, but more effectively in the MICAO group. Conclusions. The risk of SCD is higher in patients with MIwCAO, mainly due to LVEF, LV EDV, high heart rate both in the daytime and at night, SDNN index, and QT. The drugs used in patients with post-myocardial infarction may reduce the risk of SCD in patients with MICAO.

Authors: Yi Lin , Song Peng , Liu Dequan , Wang Meiqi , Chen Lei , Han Mingming
Published: February 2022

The effects of H, OH and O3 active particles on n-decane skeleton mechanism are studied under the conditions of pressure range 0.1∼1.0MPa, temperature range 1000∼1400K and equivalent ratio range 0.5∼2.0. Through sensitivity analysis, find out the elementary reaction affected by the active particles, and calculate the influence of three kinds of active particles on the ignition characteristics of n-decane. The results show that under other conditions unchanged, the higher the concentration of active particles added, the shorter the n-decane/air ignition delay time, and the addition of active particles can extend the lean burn limit of n-decane by 10%. Under 0.1MPa and 1000K ambient conditions, by adding 0.5% H, 0.5% OH and 0.5% O3, the ignition delay time of the mixture is reduced by 67.4%, 60.7%, and 16.6% respectively. With the increase of pressure and equivalent ratio, the effects of the three active particles tend to be consistent.

Comparison and Selection of Pedestrian Simulation Schemes for Reconstruction of Transfer Channel at Zhichun Road Station of Beijing Metro
Authors: Zhao Haibin
Published: February 2022

As the most critical facility of rail transit transfer station, the carrying capacity and efficiency of transfer channel greatly affect the operation efficiency and safety of transfer station. Different from the entrance and exit channels of the station, on the one hand, the transfer channel is impacted by the pulse large passenger flow with the departure interval as the cycle, and the load is large; on the other hand, due to the relatively narrow passenger circulation space, it is impossible to take operation and management measures such as flow restriction. Once serious congestion occurs, it is very easy to cause safety accidents. Due to the uncoordinated line network planning and inaccurate passenger flow prediction, the capacity of transfer channels in some transfer stations at peak hours is seriously insufficient, so they have to be rebuilt at a great cost. In the past, the comparison and selection of channel reconstruction schemes often used static calculation and qualitative analysis, which was lack of comprehensiveness. Based on the reconstruction project of transfer channel of Zhichun Road Station of Beijing Metro, this paper uses computer pedestrian simulation tools to establish three-dimensional simulation environments of different schemes, evaluates the traffic efficiency of different schemes, and recommends the better scheme in this paper in combination with the difficulty of project implementation.

Authors: Li Gaochao , Yang Jie , Zhang Anan , Cheng Lin
Published: February 2022

In order to study the relationship between joint opening changes of induced joints of concrete arch dam and dam leakage, combined with monitoring data analysis and finite element calculation method, the flow velocity distribution of six induced joints and seepage flow between joints under different openings were simulated. The correlation between joints and dam seepage and the influence of different openings on seepage flow between joints are clarified. The calculation results show that there is a strong correlation between dam leakage and joint opening, and it changes periodically with air temperature. Velocity distribution of induced joints is related to elevation. Compared with induced joints in the middle of riverbed, induced joints in the left and right bank abutments are closer. With the elevation increasing, the velocity between joints also increases gradually, and the seepage velocity near the drainage corridor is larger than that in other areas. With the increase of joint opening, the increasing rate of seepage decreases.

Authors: Wang Pingan , Shi Haibin , Hou Shouwu , Fan Liangzhi , Zhu Haiping
Published: February 2022

Deep learning has been widely used in fault diagnosis, especially the convolutional neural network (CNN). However, traditional CNN models usually use single-scale kernels to extract features, which ignores the multiscale features of input data. This article develops a novel residual neural network named multiscale feature fusion deep residual networks for fault diagnosis of aerostat. The designed multiscale feature fusion block (MFF Block) realizes automatic extraction, fusion and compression of multiscale features. The series connection of multiple MFF Blocks makes the proposed model able to extract deeper and wider features from raw signal segments. Then a multiscale pooling layer is developed to extract the most effective features for accurate fault diagnosis. The proposed model is evaluated on an exclusive aerostat strain signal dataset. The comparison results illustrate that the proposed model achieves superior diagnostic performance than several popular models.

The objective of this paper is to develop an enhanced metaheuristic algorithm to train ANFIS on solving nonlinear regression problems. Firstly, we improved the sparrow search algorithm and then proposed a simplified sparrow search algorithm (SSSA). Secondly, the SSSA was hence employed to train the parameters of an initial raw ANFIS structure for a nonlinear regression problem. In order to evaluate the performance of SSSA on the tuning of (Adaptive neuro fuzzy inference system) ANFIS, we use PSO, (gray wolf optimization) GWO and basic SSA for comparison. Finally, the results of simulations indicate that, training ANFIS by SSSA reduce the root of mean of squared error in a more effective pattern. Therefore, the proposed technique increases the way to solve nonlinear regression problems.

Authors: Yan Guihuan , Li Wei , Guo Tingting
Published: February 2022

The financing dilemma faced by technology enterprises has become an important obstacle to the further development of technology finance. This paper constructs the evolutionary game model of government, financial institutions and enterprises, introduces the project risk factor, and studies the cooperative path mechanism of multi-subjects in technology finance by combining stability analysis and SD simulation. The results show that: from the perspective of project risk, government subsidies to financial institutions are significantly better than subsidies to enterprises, and project risk plays a decisive role in tripartite cooperation. In addition to giving full play to the government’s support to financial institutions, the project risks should be reasonably evaluated to minimize the information asymmetry between financial institutions and enterprises, so as to effectively solve the financing problems of technology enterprises.

O RECONHECIMENTO NA OBRA DE NORBERT ELIAS
Authors: Santos Sergio Baptista dos
Published: February 2022

A produção teórica do sociólogo alemão Norbert Elias (1897 — 1990) aborda a relação entre poder, comportamento, emoção e conhecimento na História. No entanto toda sua obra tem como pano de fundo o que chamou de processo civilizatório que é o objeto de sua obra mais importante: O Processo Civilizador (1994). Elias nunca usou em seus escritos o conceito de reconhecimento tal qual ele é concebido na atualmente nas Ciências Sociais. A teoria do reconhecimento tem como orientação normativa o combate ao preconceito e a discriminação de determinados grupos e indivíduos, tendo em vista que a negação do reconhecimento causa danos subjetivos, constituindo-se numa forma eficaz de opressão. Neste artigo, meu objetivo é procurar mostrar como, na obra de Elias (1897 — 1990), a noção de reconhecimento social constitui-se como um elemento fundamental para construção da autoimagem dos indivíduos. Nesse sentido, procuro evidenciar que os pressupostos e conclusões desse sociólogo são semelhantes ao arcabouço teórico de um dos principais autores que trabalham com essa categoria, o filósofo canadense Charles Taylor (1931).

Plants are exposed continuously in their natural environment to diverse abiotic assaults throughout life, which leads to a decrease in yield. As a result, plants have evolved unique mechanisms at the morphological, physiological, and biochemical levels to help them resist, adapt, or survive severe environmental circumstances. Unfavorable environmental effects cause disruptions such as the inhibition of growth and photosynthesis, the closing of stomata, discoloration, and the accumulation of toxic forms of ROS in plants. However, currently, a substantial quantity of information has been gathered on the role of reactive oxygen species (ROS). Sunlight, temperature, salt content, heavy metals, air and water pollution, and UV radiation are all known to contribute to the production of reactive oxygen species (ROS) in plants. ROS harm plant systems structurally, causing a disruption in their equilibrium and the development of oxidative stress. Without appropriate control, the quantity of ROS in cells rises, causing oxidative damage to cell membranes, proteins, RNA and DNA molecules, and even cell death. It is critical to understand how plants respond to various stimuli and develop resistance to them.

The review article aims to provide a general overview of the impact of oxidative stress on biomolecules in response to different abiotic stresses.
A líbiai erőviszonyok alakulása és az aktívan érdekelt külső szereplők kilátásai
Authors: Kása Bálint
Published: February 2022

Az az egyes társadalmi rétegekben évtizedekre visszanyúló feszültség, amely az arab tavasz idején tört felszínre és a konfliktus dinamikájának legfontosabb elemét szolgáltatta, a mai napig lezáratlan polgárháborús helyzethez vezetett Líbiában. Ehhez a kezdeti éveket követően egy széles körű külső szerepvállalások is járultak. Utóbbiak mértéke és természete között markáns különbségek fedezhetők fel. A jelenkorban oly elterjedt proxyelemekkel rendelkező összecsapások számos komparatív előnyüknek köszönhetően közvetlenül és lényegesen befolyásolják a MENA-régió legsúlyosabb konfliktusait. Több tanulmány született arról, hogyan képesek külső szereplők pénzügyi, politikai, diplomáciai, katonai vagy hírszerzési arzenáljukat felhasználni rejtett agendájuk megsegítésére, hírnevük lényegi megsértése nélkül. Ugyanakkor ma már egyre kevesebben vitatják az ezen stratégiák jelenléte és a harcok elhúzódása közötti kapcsolatot. A szemben álló helyi aktorok hozzáférése a külső erőforrásokhoz ugyanis jelentősen csökkentette a kompromisszumkészséget, egyben rácáfolt a proxy és patrónus kapcsolatának klasszikus értelmezésére. Líbia évek óta egy ilyen színtér, ahol a megannyi vitatható külső hozzájárulás a küzdelmekhez csak tovább komplikálta az amúgy is bonyolult társadalmi ellentéteket. Igaz ez még akkor is, ha megállapíhatjuk, hogy Líbiában nem minden külső szereplő használ proxyeszközöket. Ezzel együtt az elmúlt egy év során történtek a status quót jelentősen befolyásoló események, amelyek tükrében érdemes felülvizsgálni a líbiai polgárháborúban közreműködő külső szerepvállalásokat. A mostani elemzés hat olyan külső szereplővel foglalkozik, akik/amelyek az utóbbi időszakban aktív részesei voltak események alakulásának. A cikk fő témaköre az elmúlt egy év eseményeinek kiértékelése, azokból következtetések levonása. Mindennek célja pedig az előttünk álló kritikus hónapok kimenetelének felbecsülése.

Published: February 2022

An important problem that is often faced by teachers in learning activities is choosing or determining appropriate learning materials or teaching materials in order to help students achieve competence. This is due to the fact that in the curriculum or syllabus, teaching materials are only written in outline in the form of "subject material". It is the teacher's job to describe the subject matter so that it becomes a complete teaching material. In addition, how to use teaching materials is also a problem. The intended use is how to teach it from the teacher's point of view, and how to learn it from the student's point of view. The purpose of this school action research (PTS) is to find out the extent to which the coaching of the Madrasah Principal improves the performance of teachers in choosing teaching materials. In this school action research (PTS), it was carried out in 3 cycles, from the results of the actions taken it was proven to be able to improve teacher performance by achieving ideal standards. From 64.47% in the first cycle, it could increase to 74.59% in the second cycle, and the second cycle. to III 83.29%. The results of this action research indicate that coaching through the academic supervision of the Madrasah Head can improve teacher performance in choosing teaching materials at MAN 1 Semarang, Semarang Regency.

Then in the coefficient of determination (R square) with a value of 0.843 which means 84.3% means that independent variables namely the turnover of receivables and inventory turnover has an influence of 84.3% on the level of Return on Assets (ROA), while the remaining 15.7% is explained by other factors that are not studied.Keywords: Receivable Turnover, Inventory Turnover, Profitability (ROA)
An Experimental Study with Objectives Functions for Portfolio Optimization Problem
Authors: Panwar Darsha
Published: February 2022

This paper presents an experimental study with the objective’s functions of a portfolio optimization problem. This study is done by three optimization problems with a different number of objectives. A hybrid approach has been adopted for this which is a combination of a few methods, such as investor topology, cluster analysis, analytical hierarchy process (AHP), and optimization techniques. Teaching-learning-based optimization (TLBO), biogeography-based optimization (BBO), and fuzzy multi-objective linear programming (FMOLP) are compared in this paper for portfolio optimization. From this research, the conclusion comes that there should not be more options in the objective functions, otherwise the motive of the portfolio becomes misleading, but many more parameters can be used for stock valuation.
HUBUNGAN KEBIASAAN OLAHRAGA DENGAN QoL PADA LANSIA DI SASANA TRESNA WERDHA
Authors: Ernawati  , Eduwar Yosep
Published: February 2022

Kualitas hidup atau Quality of life (QoL) adalah persepsi seseorang terhadap diri berhubungan dengan tujuan, harapan, standar dan perhatian di dalam konteks budaya dan nila. Lansia yang hidup di institusi perawatan lansia (residential) rentan memiliki QoL yang rendah karena dipengaruhi karena kondisi fisik, psikologis, sosial serta lingkungan. Olahraga rutin adalah kegiatan yang sering dibuat oleh pengurus Sasana Tresna Werdha (STW) untuk membuat lansia menjadi lebih sehat. Tujuan penelitian ini adalah mengetahuiadanya hubungan antara kebiasaan olahraga dengan QoL yang dilihat berdasarkan domain fisik, psikologis, dan hubungan sosial. Penelitian ini menggunakan metode penelitian kuantitatif dengan desain penelitian adalah deskriptif korelatif dengan pendekatancross sectional. Sampel sebanyak 52 lansia yang tinggal di STW. Data dikumpulkan dengan menggunakan kuesioner baku WHOQOL-BREF yang berisi 26 butir pertanyaan dan 2 pertanyaan tambahan tentang kebiasaan berolahraga. Hasil penelitian menunjukan ada hubungan bermakna antara olahraga dengan QoL lansia secara umum. Olahraga juga berhubungan dengan domain fisik (p-value=0.012), domain psikologis (p-value=0.001), serta domain hubungan sosial (p-value=0.001). Semakin sering berolahraga semakin baik QoL lansia. Kesimpulan yang dapat diambil adalah program olahragarutin dapat menjadi salah satu cara yang dapat dipilih oleh pengelola STW untuk meningkatkan Quality of Life (QoL) lansia. Masih perlu melakukan penelitian lanjutan dengan lebih banyak sampel.
