Study on the effects of different sterilization methods and storage conditions on milk quality
Authors: Khayrullin Mars , Rebezov Maksim
Published: May 2023

Milk is processed in different ways. Milk may be heated, frozen, or condensed as it is excreted in raw milk or in order to kill pathogenic microorganisms and increase shelf life. Its protein and fat content may change. Lactose is hydrolyzed, homogenized, cholesterol is removed, or fermented cultures are added to it, and its calcium levels are increased. Some special processing operations are performed to meet the consumer's needs and the specific market situation. Due to its characteristics such as relatively long shelf life, the use of UHT sterilized milk has always been associated with the suspicion among consumers that this type of milk contains preservatives or its nutritional value is greatly reduced by applying high temperatures. In this article, while briefly referring to the nutritional value of milk, the effect of pasteurization and sterilization heat on the milk components is compared. Milk is the only food known in nature that can meet the body's basic needs for nutrients in a balanced way. Milk contains a very valuable set of proteins, sugars, fats, various minerals, especially calcium and phosphorus, and a variety of vitamins. Due to its special composition, this valuable nutrient is a very suitable environment for the multiplication of pathogenic microorganisms and the transmission of diseases from animals to humans.

Authors: Irshad Ms Naila , Sumera Ms
Published: May 2023

Obesity is a compound, unending disease with numerous causes that lead to the development of metabolic diseases. Body fat itself is not an ailment, but it can change the way it functions once it gets accumulated in excess inside the body. These changes are progressive and get worse over time and thus lead to adverse health effects. A study on obesity and its complications and dietary assessment was carried out in District Srinagar of UT J&K, using a self-structured questionnaire. A sample of 150 obese individuals from both the sexes in the age group of 25-65 years, were selected by purposive random sampling technique. The sample size was limited to 150 individuals because of the financial paucity. It was found that there were various complications associated with obesity and that the intake of energy and fats was found to be more than the recommendations (RDA) given by the Indian Council of Medical Research (ICMR). Furthermore, the intake of proteins was more or less in terms of the RDA.

Published: May 2023

Historicamente, o ensino de artes marciais sempre esteve relacionado a dois aspectos fundamentais: defesa pessoal (parte física) e formação de valores subjetivos importantes para o desenvolvimento e aperfeiçoamento individual dos praticantes. O Kung Fu, arte marcial tradicional de origem chinesa, é pautado nesses aspectos e, portanto, sua prática desenvolve importantes conceitos, tais como liderança, motivação, sucesso, aprendizado, desenvolvimento, respeito, noções de hierarquia, entre outros. Este projeto de extensão irá proporcionar à comunidade da Universidade Federal do Paraná (UFPR) - Setor Palotina e à comunidade externa de Palotina e região a possibilidade de praticar Kung Fu, vivenciando conceitos filosóficos de um dos mais tradicionais estilos dessa arte marcial, o Hung Gar (ou estilo da Família Hung em livre tradução). O objetivo principal é formar um grupo de pessoas (alunos, servidores, membros da comunidade externa) que tenham interesse em praticar o Kung Fu mas não possuam condições financeiras de se matricular nas aulas disponíveis na cidade. Por meio deste projeto, os participantes terão a possibilidade de melhorar aptidões físicas, tais como alongamento, concentração, equilíbrio, coordenação motora, condicionamento e fortalecimento ósseo-muscular, bem como trabalhar conceitos subjetivos como motivação, perseverança, respeito e noções de hierarquia. Além disso, os envolvidos convivem com conceitos, filosofia e cultura chinesas, repassados tanto durante os treinos quanto em aulas teóricas. Por meio deste projeto, os alunos e demais participantes estão obtendo como resultado a consciência do seu papel na sociedade como cidadãos honestos e íntegros, que possuem autocontrole para enfrentar as adversidades que a vida apresenta no seu cotidiano.

O uso de jogos educativos, inclusive eletrônicos, pode otimizar o aprendizado no ensino fundamental, mas a literatura não apresenta estudos que comparem o uso desses recursos em escolas urbanas ou rurais. Devido à interação positiva entre crianças e animais, o tema bem-estar animal poderia ser trabalhado na escola a fim de se preparar uma sociedade futura mais consciente de seus atos em relação aos animais de estimação. Diante disso, este estudo avaliou o uso de jogos educativos no aprendizado do tema bem-estar de cães e gatos aplicados às crianças do ensino fundamental matriculadas em nove escolas urbanas (EU) e em seis escolas rurais (ER), totalizando 403 alunos. Foi elaborado um questionário sobre o tema para verificar o conhecimento prévio (QI), o aprendizado a curto prazo (QII) e a longo prazo (QIII). Nas escolas do grupo 1, houve uma palestra sobre o tema; no grupo 2, houve uma palestra seguida da aplicação de jogo eletrônico; no grupo 3, houve uma palestra seguida de jogo de tabuleiro. A curto prazo, não ocorreu diferença na retenção das informações, porém a longo prazo os jogos contribuíram no aproveitamento, principalmente quando se utilizou jogo eletrônico. Não houve diferença de aproveitamento entre as crianças de escolas urbanas ou rurais.

Published: May 2023

O presente relato busca discorrer sobre a inserção de alunos de um grupo PET Psicologia em um projeto de Extensão em Psicologia Hospitalar Infantil e à Ludoterapia, bem como seus resultados. O Grupo se inseriu em uma ONG, chamada Saúde Criança, que tem como objetivo evitar a reinternação de crianças no contexto hospitalar. A ONG trabalha em dois eixos. O primeiro é no Hospital da Criança Conceição, onde sua unidade de Recreação Terapêutica atua com uma intervenção direta com a Ludoterapia junto às crianças internadas, de modo a ajudá-las a elaborar sua internação. O segundo eixo de atuação da ONG é diretamente junto às famílias destas crianças, proporcionando treinamento profissional para ajudar as famílias a saírem de situações de vulnerabilidade social. Os integrantes do Grupo PET Psicologia se inseriram no eixo da Recreação Terapêutica, trabalhando dentro da unidade da ONG que fica no hospital. Lá, realizaram atividades de anamnese, triagem e Ludoterapia com as crianças. Observou-se que as crianças mostraram melhora significativa no humor após sua passagem pela recreação terapêutica, onde puderam expressar seus sentimentos. Uma pesquisa da Universidade de Georgetown mostrou que as crianças que receberam acolhimento da ONG Saúde Criança diminuíram o número de dias passados no hospital em 90% nos três anos seguintes à participação no programa. Aos alunos, a experiência de Extensão na psicologia hospitalar infantil foi fundamental para seu desenvolvimento como futuros psicólogos, além de terem a possibilidade de contribuir com a comunidade e na diminuição de fatores de desigualdade social.

Políticas públicas e indicadores socioeconômicos: um estudo empírico sobre os municípios brasileiros
Authors: Magalhães Ingridhe De Morais , Giovanini Adilson
Published: May 2023

O papel ativo das instituições públicas e a maior autonomia dada à esfera municipal pela Constituição de 1988, tornaram relevantes os estudos sobre as capacidades dos governos municipais e suas diferentes dimensões - técnicas, administrativas, institucionais e políticas. Nesse quadro, as capacidades municipais passaram a ter grande influência sobre a efetividade das políticas públicas e, por conseguinte, nos indicadores de bem-estar da população. Este trabalho tem como objetivo mensurar empiricamente, através de regressões, os efeitos das quatro dimensões da gestão pública - capacidades técnicas, administrativas, institucionais e políticas- nos indicadores socioeconômicos dos municípios brasileiros. Os resultados do estudo empírico apontam que, a capacidade administrativa das burocracias locais exerce influência positiva e elevada, explicando o comportamento observado para as variáveis relacionadas ao desenvolvimento socioeconômico, mensurado pelo Índice FIRJAN de desenvolvimento municipal (IFDM).  Bem como, as capacidades técnicas do governo municipal se mostraram significativas para todas as variáveis socioeconômicas. Ademais, dentre outras conclusões, os resultados indicam que a maior quantidade de servidores municipais com nível de formação de ensino médio reduz a capacidade técnica do governo local. Por outro lado, o coeficiente estimado para o número de funcionários com ensino superior apresenta sinal positivo significativo estatisticamente. Cabe ainda destacar que a orientação política do gestor municipal se mostra explicativa. Prefeitos de direita tendem a atribuir maior importância para a educação, enquanto prefeitos de esquerda tendem a conferir baixa relevância à geração de empregos e ao crescimento da renda.

Este trabalho objetiva verificar como o mercado de ações do Brasil é influenciado pelos seguintes fatores globais: mercado global de ações (S&P 500), taxa de câmbio, preço do petróleo WTI, volatilidade do mercado acionário (VIX) e índice de incerteza política dos EUA. Adotou-se a metodologia vetorial autorregressiva. Os resultados revelaram que, independentemente do período (subamostras ou total), as variáveis que afetaram de forma mais relevante o mercado acionário brasileiro foram o S&P 500, o preço do petróleo e a taxa de câmbio, variando apenas a magnitude da influência entre os subperíodos, e com grande destaque para o índice S&P 500.
Dívida pública e dependência na América Latina: os casos do Brasil, Argentina e México
Authors: Trindade José Raimundo , Frade Djalma Da Silva , Puty Claudio Castelo Branco
Published: May 2023

No último quartel do século passado o capitalismo entrou numa nova fase, centrado nos fluxos comerciais e financeiros em escala global, inaugurado ainda na década de setenta e perpetuado com a liberalização-conservadora dos principais governos do capitalismo central, de Ronald Reagan (EUA) e Margareth Thatcher (Inglaterra), projetou-se em várias experiências mundiais e latino-americanas de políticas neoliberais fundamentadas no chamado “Consenso de Washington”. A dívida pública dos países latino-americanos passou por mudanças ao longo do período neoliberal que deram impulso ao seu crescimento e que a diferencia parcialmente de seu formato no período anterior. A dívida pública se constituiu como um dos principais mecanismos de transferência de renda desta periferia capitalista para o mundo desenvolvido, refletindo na própria dinâmica de dependência e subdesenvolvimento latino-americano, inclusive nas características macroeconômicas de baixo crescimento econômico médio e crescente pauperização de sua população. O objetivo deste artigo é analisar e problematizar, com base em dados da dívida pública das três principais economias latino-americanas (Brasil, México e Argentina), os fluxos líquidos de saídas de capitais, na forma de juros e amortizações, estabelecendo a tese de que na atualidade a dívida estatal constitui um dos mais importantes mecanismos de transferência de renda para os centros dominantes  capitalistas, constituindo-se o “sistema de dívida pública” em fundamental fator de manutenção das relações de dependência e subordinação nas relações de poder econômico geopolítico.
Observation of the Coupling Current During Stress Corrosion Cracking of Aluminum Alloy 5083
Authors: Macdonald Digby
Published: May 2023

A unique fracture mechanics device was created to allow for simultaneously measuring the load and localized electrochemical potential gradients in AA5083 bend bars. For the first time, periodic Scanning Vibrating Probe (SVP) maps were collected in order to obtain a full view of the coupling current, (which can be deduced from measured potential gradients) that emanates from an anodic crack tip. As a result of mapping the current density over a wide surface area compared to the area of the notch and crack tip, clarification is given on whether or not the external surfaces of an alloy or any other metal that experiences Stress Corrosion Cracking (SCC) play a role in crack growth. The SVP maps clearly show the anodic and cathodic potential gradients of a growing crack (resulting from SCC) in an AA5083 fracture mechanics specimen while the stress intensity increases. The notch and crack-tip remained anodic throughout most of the obtained scans for sensitized and as-received specimens. Furthermore, a coupling effect is observed on sensitized specimens even at low fracture toughness values in sensitized specimens under load for longer periods of time (> 1 week). These higher resolution maps captured during the crack growth process give more insight to the SCC phenomenon and the electrochemical mechanisms of crack growth in AA5083 and other alloys.
Study on the hindrance mechanism of green finance promotion based on ISM-MICMAC
Authors: Sun Nuolin , Yang Lei , Lin Tingting
Published: May 2023

The G20 Sustainable Finance Report 2022 was adopted at the G20 Summit in 2022, signaling a global agreement on green finance in a growing number of nations. Since then, the use of financial instruments to accelerate the transition to green development and meet the dual carbon goal has gained significant public attention. In this essay, 18 variables that hinder the development of green finance are compiled and identified using a literature review methodology. The explanatory structural model (ISM) model is used to analyze the relationship mechanism between the impeding factors and the promotion of green finance, and the Matrices Impacts Croises-Multiplication Appliance Classement (MICMAC) approach is used to categorize the 18 impeding factors into the driving force-dependency classification. The results show that improving the surface factors with strong dependencies, such as willingness to use green transition funds, scope of supporting industries, capability of industrial restructuring, and difficulty of application, etc., is especially important for promoting green finance. Focus should also be placed on the deeper factors with strong driving forces, such as the lack of regulation of relevant national laws and the restricted freedom of local policy implementation, etc. This paper takes the hindering mechanism of green finance promotion as the research object, and researches to get the hindering chain of the influence of four different dimensional mechanisms on green finance promotion, which is helpful to provide the solution direction when green finance development faces problems.

Published: May 2023

This study proposes a stock price forecasting model based on Kernel Principal Component Analysis (KPCA) and Light Gradient Boosting Machine (LightGBM) to examine the connection between the impact factors and the CSI 300 index. As a case, this study focuses on the CSI 300 Index. Data gathered from January 2005 to July 2022, including 16 clear indicators such as CPI, IPI, and Dow Jones Industrial Index, were simplified into five dimensions by the KPCA. Subsequently, the LightGBM algorithm was applied through 5-fold cross-validation to adjust the parameters and achieve optimal model performance. The results demonstrate that the combined KPCA-LightGBM model has strong generalizability and stability, with an RMSE and R2 of 0.001 and 0.837, respectively. Furthermore, reducing factors to five dimensions by KPCA can also provide improved decision-making metrics for investors.

The difference of 0.01s is enough to decide the winner of a race. To push oneself to the limit through training is the meaning of sports, and to seize every second by helping athletes polish details and optimize tactics is the meaning of modern sports technology. This is evident in the Individual Time Trial (ITT), a race that focuses on tactics and details. In order to help riders achieve better results, it have created optimization methods for each type of rider and course, taking into account energy reserves (stamina), rider power and course conditions. So, several models are developed in this paper: scoring weighted regression model and energy-power model based on Skiba model.

The continuous technological revolution has opened new business avenues and payment systems that most of the population have accepted, especially the younger generation. This study aims to explore and highlight the factors limiting the adoption of online payment systems among the elderly and middle-aged people. The study considers the influence of technological advancements and social media platforms on online payment adoption. Face-to-face interviews were used as the main tool for collecting data from 35 participants, out of which 22 reported using online payment systems. The data collected was analyzed using the Three Scheme Comparison Table. The results from study showed that online payment adoption among the elderly and middle-aged people is limited by various factors, including age, gender, occupation, area of residence, and income. The study also found that the majority of the participants who adopted online payment systems had a monthly income, which suggests that financial stability may be a key factor in the adoption of online payment systems. However, technological advancements, such as the increased availability of mobile phones and access to the internet, have positively influenced the adoption of online payment systems among the participants especially in urban areas.

Published: May 2023

The ecological environment is closely related to the quality of human life. In recent years, more and more people have realized the importance of protecting the ecological environment. Therefore, the selection of GGDP as the evaluation standard of national development level is more suitable for the sustainable development of human beings. This paper makes an in-depth study on the impact of using GGDP accounting model on the subsequent national development. First of all, we refer to the current three convincing GGDP accounting models, and select the most suitable GGDP model through quantitative indicators, and we have optimized some details on the existing GGDP model. Then, proving that GGDP replaces GDP can slow down the rate of global warming and reduce the frequency of natural disasters. Second, we illustrate the potential benefits of climate mitigation and the negative impact of efforts to change the status quo from multiple aspects, fully demonstrating that the choice of GGDP is worthwhile. Finally, we have analyzed its impact on China in terms of policy, energy use structure, index system and public awareness of environmental protection.
The Recent Progress and State-Of-Art Applications of CAPM Model
Authors: Cui Yina
Published: May 2023

Conventionally, CAPM model is widely used to estimate the value of securities, but it is not efficient in Chinese securities market due to the non-systematic risk. Therefore, this paper aims to analyze the development of CAPM multi-factor model and multi-effect Asset pricing (e.g., the Fama French multi-factorial model). Primarily, this paper introduces the background and function of CAPM model. Afterwards, it is pointed out that more factors need to be considered to improve the performance of CAPM model. Therefore, Fama-French models of three-factor and five-factor are demonstrated. The paper analyses the evolution of CAPM multi-factor models and indicates that the CAPM model is unable to well explain the long-run premiums of small-size company stocks in Chinese market. Finally, the paper discusses the limitation of this research and look forward the further research. These results shed light on the future development of financial pricing models.

Published: May 2023

Due to the continuous improvement of quality of life and more stable social environment, the population is growing rapidly. Among them, population forecasting plays an important role in solving the problems brought by population growth. Based on the data indicators such as population, fertility rate and median age in China’s mainland from 1955 to 2022, the logistic regression model is usually used to predict the future population. This model is trained by Hyperopt to obtain the optimal parameters, it can improve the accuracy of the model. In addition, in order to show the differences between different models, this experiment also used random forest model to predict. The experimental results show that the population growth rate will slow down gradually and reach the maximum population in around 2030, after which it will show negative growth. By calculating the mean square error, it shows that the machine learning model can provide learners with accurate population prediction results.

Authors: Jia Yuhao , Duan Muyan
Published: May 2023

The urban tree canopy is widely recognized as an urban resource that contributes to the physical and mental health of residents, yet tree inequality is widespread. To achieve the goal of promoting tree equity and filling the gap in relevant academic research, this study develops a 2-step 9CNN model to obtain highly accurate urban tree canopy (UTC) data from high-resolution satellite images. New York City tree canopy data is obtained by this new method and correlates with New York City socioeconomic data to examine UTC's horizontal and vertical equity. OLS regression correlations of per capita UTC area with the number of elderly, poor, low-educated, and disabled were used to measure vertical equity. To avoid the interference of spatial autocorrelation, GWR models were used to test for spatial differences in vertical equity. The results of the horizontal equity study show that there is far less UTC space per capita in New York's urban centers than in the fringe areas. Vertical equity in UTC is poor across all of vulnerable groups and is particularly pronounced in some regions. These findings can subsequently help to develop policies for UTC equity and environmental justice concerns.

Published: May 2023

The power sector is an important area for achieving the 'double carbon' target.To achieve the "double carbon target" in Beijing as early as possible, this thesis is based on the LEAP model, which is a bottom-up study of the carbon peaking and carbon neutral pathways in the power sector from the perspective of the whole chain of source, grid, load and storage. It also combines scenario analysis, taking into account emission reduction targets, electricity demand and resource deployment, to design four comparison scenarios. These are the basic scenario, the energy efficiency improvement scenario, the transport electrification scenario and the renewable energy development scenario. The study focuses on the potential for emission reduction and feasible paths for the energy transition in Beijing's power sector. Finally, policy recommendations are made to promote the energy transition in Beijing.
A study of light pollution risk level assessment based on multiple linear regression
Authors: Chen Xiao
Published: May 2023

Light pollution is affecting modern people’s lives, and it may damage people’s health and safety. To develop an applicable metric to identify the light pollution risk level of a location, this paper first analyzes the correlation of factors affecting light pollution, and obtains that the correlation coefficient with light pollution mainly includes population density, per capita income, GDP, green coverage, the proportion of the tertiary industry and employment rate. Select these explanatory variables which have high linear correlation with the degree of light pollution to establish a multiple linear regression model. Then, carry out heteroscedasticity and multicollinearity tests on the model, and next, after removing the three variables of population density, per capita income and the proportion of tertiary industry, the optimal linear regression model is determined through OSL. Finally, different levels of light pollution are classified by DN value, which represents the night light of a location, to achieve the assessment of light pollution risk level.

The Yarlung Zangbo River is rich in water resources, which is of great significance to the comprehensive utilization of water resources. The reasonable development of the hydropower resources of the Yarlung Zangbo River is realized, through the water diversion project and the establishment of the trapezoidal hydropower station. A comprehensive utilization model of hydropower resources optimized by discrete objectives is constructed, based on the discrete multi-objective optimization theory. It combined with the reading of geographic data by GPS and Matlab. The number and orientation of the optimal construction of hydropower stations and the proportion of the water transfer volume of the water diversion project are obtained, combining the cost of hydropower station construction and water diversion project implementation and the benefits brought by hydropower resources.

Authors: Wang Hongqing
Published: May 2023

In the 19th century, the Industrial Revolution brought major changes to the environment as industrialization and urbanization accelerated. These changes will have a serious impact on the natural environment and human life. At present, how to mitigate environmental changes has become a problem that needs to be faced directly. This paper mainly studies the main causes of environmental change and puts forward corresponding countermeasures, and thus concludes that the main causes of environmental change include climate change caused by soil erosion and greenhouse gas emissions. Therefore, it is very necessary to carry out sustainable development. The whole world should work together to reduce greenhouse gas emissions to slow down climate change, switch from fossil fuels to renewable energy, improve energy efficiency and reduce deforestation to reduce soil erosion. Ultimately, by working together across society to address environmental change and sustainability, with the right policies, technologies, and social changes, we can create a more sustainable future for the planet and its inhabitants.

Published: May 2023

Global light pollution is darkening the stars in many parts of the world, even endangering humanity and the environment. Therefore, in order to mitigate the effects of light pollution and make the stars shine brightly in the sky, we do further research on the problem of light pollution. First, in order to determine the light pollution level in specific areas, we established the light pollution risk level assessment index system (LPRL). Based on the hierarchical analysis process (AHP) and the entropy weight method (EWM), we selected three first-level indicators. Next, we first estimated the LPRL for the four selected sites protecting land location, rural, suburban, and urban communities. Then, we proposed three reasonable and effective intervention strategies from the perspective of preventing light pollution sources, reducing light pollution hazards, and reducing light pollution transmission. Finally, we selected two sites in the suburbs of Shanghai and central Shanghai and identified their best intervention strategies by qualitative analysis.
Assessment of adsorption materials for carbon capturing and storage in the context of carbon neutrality
Authors: Li Zhuozheng
Published: May 2023

In order to avoid the harm caused by global warming, carbon capture and store (CCS) technology has become a global hot topic. CO2 adsorption materials are an important basis for the realization of CCS. This paper explores the CO2 adsorption mechanisms of the currently widespread shale reservoirs, metal-organic framework (MOF), covalent-organic framework (COF), activated carbon and evaluated the relevant factors affecting their adsorption capacity. Through the exchange of CO2 and CH4, shale reservoir is a natural material with great CO2 adsorption and storage potential. However, due to the high implementation cost and the uncertainty of porosity, this technology is considered to be immature. MOF and COF have different chemical bonds, but they are both crystalline compounds with tunable porosity and internal surface area. They are very ideal CO2 adsorption materials. However, the main disadvantage of MOF and COF lies in their instability. Moreover, activated carbon is considered to be the adsorption material with the lowest production cost among the four. The adsorption performance of activated carbon is related to its raw materials, internal surface area, pore properties and external functional groups. However, activated carbon ashes are likely to cause secondary environmental pollution. In the future, it is necessary to improve the prediction accuracy of the adsorption potential of shale reservoirs, solve the unstable characteristics of MOF and COF, and maximize the adsorption performance of activated carbon in an environmentally friendly manner. The significance of this article is to provide theoretical support for the optimization and development of physical adsorption materials in the future.
Evaluation of the Effects of Airflow Patterns on Human Thermal Perception
Authors: Chu Jiaoyang
Published: May 2023

Recently, greenhouse gas emissions have led to irreversible climate change, and in order to mitigate the changes, more and more research is focusing on energy efficiency and environmental protection in the building sector. Improving indoor ventilation airflow as a feasible solution for energy conservation as well as improving human thermal comfort. This study aims to provide reference for optimizing the thermal perception of occupants in indoor ventilation design. This research evaluates the effect of heat perception on students in a stable indoor environment (28 ℃, RH 50%) under two airflow patterns (dynamic and constant). The use of airflow was found to have a positive impact on thermal sensation vote (TSV) and thermal pleasure vote (TPV). There was non-significant difference in the effects of heat perception between airflow modes. This finding is consistent with the findings of Parkinson and de Dear's study. It is worth noting that differences in experimental results may be due to other personal factors (e.g., gender, age, and weight). Further studies are therefore needed to demonstrate the influence of these factors on the thermal perception effect of air movement.
