APIR: metodología para la evaluación y priorización del riesgo en planes HACCP
Authors: Cartín-Rojas Andrés , Cediel Becerra Natalia , Monroy López Francisco
Published: June 2022

Introducción: Se propone una metodología de priorización basada en riesgos de tipo ascendente para diferentes peligros y matrices alimentarios, denominada “APIR”. Las variables del modelo se encuentran subdivididas en dos categorías: a) las características del peligro, donde se cuantifica la probabilidad de ocurrencia y severidad. b) las propiedades de la matriz alimentaria que estiman su riesgo epidemiológico, presencia en el alimento y vulnerabilidad de su manufactura. Se establece un Índice de Riesgo (IR) como parámetro para facilitar que los gestores de inocuidad alimentaria discriminen y prioricen los Peligros Significativos durante la identificación de peligros de los planes HACCP. Objetivo: El objetivo de este trabajo fue establecer una metodología flexible y dinámica de priorización basada en riesgo para empresas procesadoras y transformadoras de productos de origen animal destinados al consumo humano e integrarla con los planes HACCP, permitiendo establecer controles específicos en el proceso productivo. Resultados: Los valores de la significancia entre los nodos Nrp y Nrm fueron de p<0,05. Se estimó el Coeficiente de Correlación de Spearman (rho) para determinar la proporción de variación entre los mismo predictores. Los resultados obtenidos fueron Or-Nrp (rho= 0,719, p= <0,001), Se-Nrp (rho= 0,888, p-valor= <0,001), Re-Nrm (rho= 0,560, p-valor= <0,001), Pm-Nrm (rho= 0,696, p-valor= <0,001) y Vd (rho= 0,687, p-valor= <0,001), respectivamente. Se incluye un estudio de caso para simular el modelo y demostrar su operatividad. Discusión: Los resultados obtenidos demuestran la replicabilidad y validez del presente modelo. Se propone el nombre de APIR (Análisis de Priorización basada en el Índice de Riesgo) para esta metodología.

Published: June 2022

An electrocardiogram (ECG) pattern classification method has been
proposed to distinguish heart conditions such as arrhythmia (ARR) and
congestive heart failure (CHF) from normal sinus rhythms (NSR) using
deep convolutional neural networks (CNNs) by converting the ECG signals
into RGB images. The results demonstrate an increase in diagnostic
accuracy from 90.63% to 94.12% using a pretrained CNN model by
utilising additional data from the second lead of the ECG.
Development of Simplified Hysteresis Model with Strain Hardening and Pinching Effects
Authors: Hazra Abhishek , Das Prithwish
Published: June 2022

Other than most of the existing sophisticated complex hysteresis models,
this study provides a simplified degraded and deteriorated hysteresis
model which can capture the cycle by cycle progressive damage with
greater accuracy due to inelastic reversal loading. The attention to the
proposed developed hysteresis model is given to capture the overall
behavior of the structure. The effect of post-yielding stiffness and
pinching resulting from high shear loads and slippage of longitudinal
reinforcement in Reinforced Concrete(R/C) members are considered and
incorporated in the proposed developed hysteresis model. Based on the
superimposition of curves and a comparison of hysteretic energy
dissipation between the simplified developed hysteresis model and the
previous model, minor deviations in the prediction of the inelastic
cyclic behavior of R/C structural members are observed.

Published: June 2022

Leaf morphology is at a certain level defined by the ways in which plants adapt to different habitats, especially in large trees. In this study, morphological variations in leaf size and shape of the Hungarian oak (Quercus frainetto Ten.) growing on different soil types (lithic leptosol, vertisol, cambisol) were investigated in the central part of Serbia (Sumadija). The information on soil type was obtained using a digitalized soil map of the Republic of Serbia, while leaf traits were characterized by geometric morphometric methods. Landmark analysis and leaf measurements showed significant differences among the analyzed groups, with individuals growing on nutrient-poor, shallow soils having smaller leaves with greater lobation. The observed differences suggest that the levels of soil productivity influence variations in leaf patterns. More studies on a larger sample size and along a broader spatial scale are needed to fully understand the differences in the patterns of leaf morphological variation in Q. frainetto.
An American Utopia and Its Global Audiences: Transnational Perspectives on Looking Backward
Authors: Guarneri Carl J.
Published: June 2022

This essay departs from conventional American Studies treatments to resituate Bellamy's utopia of 1888 within transnational debates over industrialism, socialism, and the state in European nations and their settler societies (including the United States) between 1890 and 1940. Building upon critical studies and information about the reception of Bellamy's utopia abroad, it offers three approaches: a genre-based analysis of the utopian hybrid that suggests textual bases for multiple readings; a transnational history of evolutionary socialism that helps explain Bellamy's global relevance in the 1890s and again in the 1930s; and a comparative approach that contrasts the reception of Looking Backward in different national contexts. In the face of traditionally exceptionalist scholarship and the narrower, nationalistic frame of Bellamy's sequel, Equality (1897), to understand Bellamy's global appeal we must recover the international context of Looking Backward and the internationalist views expressed in its pages.
The Fall and Rise of an Antipodean Utopia: Brisbane, Australia
Authors: Metcalf William (Bill)
Published: June 2022

This article describes and discusses a late-nineteenth century utopian text, The Curse and Its Cure, set in the city of Brisbane, capital of the state of Queensland, Australia. The first half of this book by Dr. Thomas Pennington Lucas posits how Brisbane was utterly destroyed in the early twentieth century so that by the time at which the story is set—in the year 2000—little remains of the abandoned city except scattered ruins overrun with weeds and vermin. In the second half, Lucas postulates how, by the year 2200, Brisbane had become the New Jerusalem in the South Pacific, a true Utopia leading the world to morality, affluence, peace, and sanity. The Curse and Its Cure has long been out of print and, as far as can be discovered, only one full copy and one partial copy remain, both held by the John Oxley Library, Brisbane. I uncovered it as part of my research into Australia's utopian literature. Although other Australian scholars such as Nan Albinski, Vincent Buckley, Verity Burgmann, Andrew Milner, Bruce Scates, Richard Trahair, and Robyn Walton (as well as an American academic, Lyman Tower Sargent) have all written about the prodigious amount of Australian utopian literature, none of them discovered Lucas's text.
From Utopia to Empire: Atarashikimura and A Personal View of the Greater East Asia War (1942)
Authors: Yiu Angela
Published: June 2022

Atarashikimura—“New Village”—was founded by the Japanese writer Mushakôji Saneatsu (1885—1976) in 1918 based on the utopian principles of restoring dignity to labor, communal living, and the actualization of the authentic self in artistic pursuits. The rhetoric and rationale of utopia extended to the founding of the puppet state of the Manchukuo in the 1930s as Japan's imperialism intensified. By 1943, Mushakôji wrote the infamous A Personal View on the Greater East Asia War, using the rhetoric for utopia to argue in favor of the Greater East Asian Co-prosperity Sphere. This paper will examine the allure and danger of Mushakôji's rhetoric of utopia, and how such rhetoric contributes to the escalation of war and colonization.
Power, Utopia, and the Manipulation of the Historical Consciousness: Perspectives from Collingwood
Authors: Jenson Michael
Published: June 2022

A recurrent misconception about the concept of utopia fails to realize fully that its essential endeavor constitutes a speculative act involving the distribution of power and resources. Consequently, utopian desire is closely linked to structures of power and can be manipulated by interests in positions of influence within these structures. It is these connections to the machinations of power that bring utopian visions their potential for social/political influence. However, these same types of links also provide avenues for these conceptions to be cynically influenced in ways that can usurp individual autonomy. The role of power and utopia can be analyzed in the formative process of a specific social structure as well as in their contribution to the conception of a common heritage or history. The “historical perspective” often serves as the foundation for the production of propaganda seeking to capture the imagination of a populace either to instigate positive social change or to legitimize an oppressive regime. Through the lens of Collingwood's philosophy of history, this article investigates the connection that the “historical consciousness” has to the attributes of power and utopia as well as the role that this relationship plays in the formation of a collective mentality. In short, it studies the essential characteristics of the bond between individuals that allows a community or collective to perpetuate itself. It also explores how the attributes of power and utopia can use latent historical perceptions to strengthen the process of ideological integration that underlies any social action or formal structure of authority.
Socio-economic Utopianism in Spain at the End of the Nineteenth Century: La Nueva Utopía by Ricardo Mella
Authors: Ramos-Gorostiza José Luis
Published: June 2022

In 1890, Ricardo Mella—one of the foremost theorists of Spanish anarchism—published the short novel La Nueva Utopía [The New Utopia], which had been awarded a prize in Barcelona's Second Socialist Contest the previous year. It was a time of resurgence for the utopian novel in the western world with numerous proposals for different models of socialism. In particular, there were three works in quick succession which were well received and eventually became classics: Bellamy's Looking Backward (1888), Hertzka's Freiland (1889), and Morris's News from Nowhere (1890). This article analyzes Mella's novel as the major example of the utopian genre in Spain at the end of the nineteenth century and as an effective means of spreading his model of anarchist collectivism (as opposed to anarchist communism). In it, he shows the future libertarian society in glowing colors. In addition, the article compares the model of social organization developed in La Nueva Utopía with those proposed in the three famous contemporary works (by Bellamy, Hertzka, and Morris).

Published: June 2022

The main system responsible for the safety of the car is its braking system. The efficiency of the braking system is assessed by several parameters, the main of which is the maximum braking force, which is generated in the braking mechanisms, usually it is disc or drum types of brakes. The analysis of peculiarities of designs of existing types of brakes of cars is carried out, advantages and disadvantages of each of them, characteristics of application and maintenance are substantiated. The main factors that have a significant impact on the efficiency of the car's brake system have been identified. It was carried out the research of the influence of the main operational factors on the efficiency of the car's brake system: the pressure in the car's tires, contamination, and friction pairs of the brake mechanisms. The method of conducting experimental test lane and road researches of influence of the chosen factors on indicators of braking efficiency of the car is developed. Test lane experimental studies were performed using the Bosch BSA 4340 brake test equipment, graphs of changes in the braking efficiency of each of the car's wheels based on the researches were built, depending first on the change in tire pressure, then on the presence of rust, grit, and grime and level of wear of mechanisms. The quantity of the maximum braking force of the car depending on three quantities of pressure in tires of wheels was identified: the pressure recommended by the factory of 0,18 MPa, the lowered and increased pressures 0.15 and 0.25 MPa respectively. The influence of motor oil caught in the brake mechanism or treatment with special pastes on the value of the maximum braking force is also determined. The influence of the state of the brake discs and pads on the braking efficiency of the car was also investigated, the braking indicators were measured before and after the replacement of the brake disc and pads. On the basis of the conducted test line and road researches, conclusions are made and practical recommendations on prevention of reduction of brake efficiency of the car in the conditions of operation are offered.

Peramalan mutlak diperlukan dalam rangka pengembangan sumber daya air khususnya sungai. Peramalan dengan didasarkan pada konsep tampungan merupakan suatu peramalan yang menjadikan imbangan air sebagai konsep dasar dalam perhitungan. Imbangan yang dimaksudkan adalah hubungan antara masukan (hujan) dengan keluaran (limpasan). Dalam hubungannya antara imbangan air dengan waktu tidaklah selalu terjadi hubungan yang selaras dan seimbang antara masukan dan keluaran. Dalam artian bahwa selisih antara masukan dan keluaran tidaklah selalu nol, melainkan akan selalu terjadi selisih nilai antara keduanya yang diasumsikan bahwa selisih tersebut merupakan kehilangan air yang diakibatkan oleh adanya tampungan pada DAS bersangkutan. Untuk itu salah satu solusi penyelesaian masalah yang dapat dilakukan adalah mencari bentuk dan fungsi dari kurva yang mewakili data tersebut. Melalui pendekatan menggunakan deret fourier akan terbentuk kurva yang mewakili titik-titik terukur dengan selisih antara titik-titik terukur dengan hasil pendekatan menjadi sangat kecil.

PERAMALAN HARGA CABAI RAWIT DI KOTA MALANG DENGAN METODE HOLT-WINTERS EXPONENTIAL SMOOTHING
Authors: Siregar Ynez Juylette , Hartono Rachman , Hardana Andrean Eka
Published: June 2022

AbstrakHarga cabai rawit yang berfluktuasi menyebabkan petani cabai rawit takut akan adanya kerugian karena tidak dapat memprediksi harga. Salah satu cara yang bisa dilakukan untuk mencegah kerugian adalah dengan melakukan peramalan (forecasting). Peramalan merupakan metode yang digunakan untuk memprediksi sesuatu di masa depan menggunakan data di masa lalu. Salah satu metode peramalan bernama Holt-Winters Exponential Smoothing, merupakan metode yang biasa digunakan pada barang yang memiliki pola harga musiman, sesuai dengan cabai rawit yang merupakan tanaman musiman. Peramalan yang dilakukan menggunakan data sebanyak 108 buah, yaitu data harga rata-rata bulanan cabai rawit di Kota Malang dari 2012-2020. Menggunakan nilai inisialisasi level 0.99, trend 0.01, seasonal 0.01, didapatkan MAPE sebesar 31%, MAD sebesar 9762, dan MSD sebesar 183465457. Hasil peramalan harga cabai rawit di Kota Malang untuk tahun 2021 mengalami pola naik dan turun. Bila dibandingkan dengan data aktual, harga peramalan lebih rendah daripada harga aktual, tetapi pola yang dihasilkan sama, dikarenakan musim penghujan dari bulan Januari yang menyebabkan petani menjadi gagal panen, dan harga melambung tinggi. Rekomendasi untuk para petani di Kota Malang adalah dengan mengatur luas tanam pada saat musim penghujan, melakukan penanaman secara tumpangsari, menjual cabai rawit dalam bentuk selain cabai rawit segar, dan menjalin kemitraan dengan perusahaan.Kata kunci: cabai rawit, peramalan harga, holt-winters exponential smoothingAbstractThe fluctuating price of rawit chilli causes rawit chilli farmers to hesitate to plant rawit chilli, because they are afraid of losses. A way that can be done to prevent losses is by forecasting. Forecasting is a method used to predict something in the future using data from the past. One of the forecasting methods is called Holt-Winters Exponential Smoothing, which is commonly used for goods that have seasonal price patterns, and one of them is rawit chilli. Forecasting is done by using 108 data units, consist of data on the monthly average price of rawit chilli in Malang City from 2012-2020. With level initialization value of 0.99, trend of 0.01, seasonal of 0.01, they produce MAPE of 31%, MAD of 9762, and MSD of 183465457. The results of forecasting of the rawit chilli’s price  experience up and down pattern. When compared with the actual data, the forecasted price is lower than the actual price, but the pattern is the same, due to the rainy season from January which causes farmers to fail, and prices soar. Recommendations that can be given to farmers in Malang City are to regulate the planting area during the rainy season, do intercropping, sell rawit chilli in forms other than fresh rawit chilli, and establish partnerships with companies.Keywords: rawit chilli, forecasting, holt-winters exponential smoothing

Biji alpukat mengandung beberapa senyawa metabolit sekunder diantaranya alkaloid, flavonoid, tanin, saponin, terpenoid atau steroid dan fenolik. Senyawa kimia yang berperan sebagai antioksidan adalah senyawa flavonoid dan tanin. Jenis flavonoid dalam biji alpukat yaitu kuersetin. Kuersetin memiliki karakteristik fisika kimia yang sukar larut dalam air. Kelarutan obat yang tidak baik memiliki bioavailabilitas yang rendah sehingga ekstrak biji alpukat ini dibuat dalam bentuk nanopartikel karena sediaan nanopartikel bersifat biodegradable yang digunakan untuk meningkatkan kelarutan obat yang sukar larut dalam air dengan meningkatkan bioavailabilitas. Metode pembuatan nanopartikel dalam penelitian ini yaitu menggunakan metode solvent evaporation dengan cara bahan obat dicampurkan dengan suatu polimer dan menggunakan pelarut etil asetat. Nanopartikel dibuat dalam empat formula, dengan memvariasikan konsentrasi dari PLGA. Nanopartikel yang terbentuk kemudian dikarakteriasasi meliputi pengujian ukuran partikel, nilai zeta potensial, indeks polidispersitas, efisiensi penjerapan, bentuk morfologi partikel menggunakan SEM. Hasil nanopartikel yang terbaik didapat pada formula F4 yang memiliki karakteristik mutu fisik terbaik dengan ukuran partikel 137,1 nm; Indeks Polidispersitas 0,336; Zeta potensial -19 mV; efisiensi penjerapan 85,63% dan morfologi pada perbesaran 30.000x berbentuk bulat atau sferis.

Application and Innovation of Electronic Monitoring in Chinese Criminal Justice
Authors: Chao Wang , Yahong Wang
Published: June 2022

In the field of criminal justice, electronic monitoring technology has experienced the development of four generations of technology: fixed telephone, radio frequency tag, Global Positioning System, and biometrics. Today, Chinese criminal justice practice adopts a monitoring method based on cell phone positioning, supplemented by electronic anklets. The "Non-custodial Code monitoring system " is an innovative achievement of Hangzhou, China's judicial personnel on electronic monitoring, which has achieved good practical results and will be promoted nationwide. As an effective criminal measure, electronic monitoring reduces the number of detainees in prison, eases the supervision pressure on judicial personnel, reduces financial expenditures, and helps criminals rejoin society. Due to the lack of detailed legal provisions, the application of electronic monitoring in practice lacks specificity, and there is the possibility of violating the privacy of citizens. So electronic monitoring in China's criminal justice presents such a situation. On the one hand, the law clearly states that electronic monitoring can be applied only during the community correctional stage and the period of residential confinement. On the other hand, judicial officers actively try to apply electronic monitoring to the bail process. It is foreseeable that electronic monitoring will be widely promoted in the process of China's criminal justice reform. This process should adhere to the principles of legality, necessity, and judicial review.
Infrastructure development, environmental quality and economic growth in Nigeria

The earth as a planet supports human life, and human activities attract extensive and intensive socioeconomic influence on the environment and the economy. Activities such as infrastructure development exert increasing and diverse concerns on environmental quality and hence on economic growth. While these variables appear interrelated due to many factors, including population growth, urbanization, industrialization, etc., however, the nature of the interrelationship is not largely known, especially in Nigeria. This study therefore investigated and examined their relationship using time-series data between 1990–2019 by adopting the co-integration estimation technique through the bounds test approach of the autoregressive distributive lag (ARDL) method, using the percentage share of the building and construction sector (BCS) of GDP, carbon dioxide percentage of fuel combustion (CTE), the annual growth rate of agriculture (AFF), the annual population growth rate, the annual GDP growth rate, etc., as variables. The study revealed that infrastructure development and environmental quality explain economic growth and they all have both short- and long-run relationships, while population growth and AFF variables are positively significant to economic growth. The finding evidenced the significance of the relationship and consequently recommended new roles for infrastructure and production processes that consider environmental-quality mindsets to achieve positive outcomes of green economic growth in Nigeria.
Renoprotective mechanisms of SGLT2 inhibitor in diabetic kidney disease
Authors: Yan Hongru , Wen Yi , Liu Bicheng
Published: June 2022

Diabetic kidney disease (DKD), as the primary cause of end-stage renal disease (ESRD), is becoming a growing public health challenge worldwide. Early intervention in conditions involving high glucose levels will prevent the progression of DKD. Sodium-glucose cotransporter 2 inhibitors (SGLT2is) comprise a new class of medications used to reduce hyperglycemia in patients with diabetes by inhibiting renal reabsorption of filtered glucose. Interestingly, SGLT2i is not only capable of controlling the blood glucose level but also has other benefits in terms of blood pressure control, body weight decrease, and albuminuria reduction. It is assumed that various events, such as energy metabolism disorder, insulin resistance, glomerular hyperfiltration, oxidative stress, inflammation, and fibrosis, attributable to the pathogenesis of DKD, can be improved by SGLT2i. Clinical trials have demonstrated that SGLT2i can exert renoprotective effects and reduce the morbidity and mortality due to ESRD. In this review, we focus on the most recent findings from clinical trials and the underlying mechanisms by which SGLT2 inhibitors afford renal protection.

The transport sector accounts for about one-third of the final energy consumption in Latvia, most of which are fossil fuels in road transport. Fossil fuel consumption increases emissions and demands an immediate change in mobility habits to achieve climate neutrality by 2050. This paper focuses on the in-depth analyses of passenger transport by modelling the potential use of cleaner energy sources and the possible decrease of consumption through the modal shift. As travel modes differ for each distance, the study is done for three distances – short, medium and long. Three scenarios have been analysed – BASE scenario including existing measures and taxation policy, NECP scenario including measures defined in the National Energy and Climate Plan until 2030 and GHG TARGET scenario aiming to achieve climate neutrality by 2050. The proposed modelling approach allows for the development and evaluation of the effectiveness of existing and planned measures in greening mobility. Results proved the need for immediate action and a change in the mobility habits of the population to achieve climate neutrality by 2050.
