Published: August 2022

Introduction: Because of the introduction of improved technology like diathermy and visual scopes, Transurethral resection of prostate (TURP) has become a comparatively safer treatment in recent years. However, there is a danger of developing TURP syndrome and electrolyte imbalance, particularly in individuals with high-risk cardiac disease. Aim: This study was performed for the identification of course, duration, and occurrence of complications in post-operative patients with TURP. Materials and Methods: A descriptive study comprising 52 patients was conducted at C.U. Shah Medical College and Hospital, Surendranagar, Gujarat, India from 8th February 2019 to 1st November 2020, covering 20 months. Results: The study focused on the distribution of patients as per age and post-op complications, co-morbid conditions, DRE grading, etc. Also, the study correlates the volume of the prostate with post-operative complications, prostate volume with S-PSA, etc. Furthermore, the study focused on early complications after TURP as well as late post-operative complications after TURP. Conclusion: This descriptive observational study highlighted several postoperative complications after TURP. It was observed that the incidence of complication rate is increasing with an increasing volume of the prostate.
Sistema preventivo y finalidad educativa del derecho penal juvenil
Authors: De Rosa Pablo Alberto
Published: August 2022

Una de las características especiales que presenta la justicia penal juvenil respecto a la de adultos, es el tipo de respuesta que se proporciona al infractor. En el derecho penal del adolescente se parte de la base de que los fines preventivo-especiales juegan en él un papel central y protagónico, privilegiando la intervención educativa por sobre la retributiva. Esta prevención especial positiva es entendida en términos de resocialización del adolescente con objetivos socioeducativos de retsponsabilidad penal del mismo, orientado a la educación para la vida en sociedad. Aquí se expone la vigencia del sistema preventivo propuesto por Don Bosco, receptado implícitamente en el pensamiento penal juvenil contemporáneo y en organismos internacionales de derechos humanos. Estos sostienen que la mejor manera de combatir la delincuencia juvenil es la prevención por medio de política social y educacional, y no con la imposición de sanciones privativas de libertad, que deben ser utilizadas tan solo como último recurso y por el tiempo más breve que proceda.

Published: August 2022

Neste texto trazemos à cena a experiência recente de uma unidade universitária federal de educação infantil (UUFEI), cuja origem, na década de 1970, está ligada à luta por creches em local de trabalho. Situada na região sudeste do país, a instituição consolidou-se como importante lócus para a realização de pesquisa, extensão e estágio, principalmente da área da saúde e, mais recentemente vem constituindo-se como campo de produção e socialização de conhecimento especializado sobre a infância e a educação da infância.  Trata-se de um estudo qualitativo de cunho exploratório, que partiu do mapeamento das ações de pesquisa e extensão desenvolvidas no âmbito desta UUFEI no período de 2016 a 2020, e teve como objetivo de compreender seu impacto na qualificação das práticas educativas e no currículo a que as crianças  têm direito na instituição. Os resultados revelam uma ênfase em atividades voltadas para retroalimentação das práticas educativas, evidenciando uma busca permanente para consolidação de conceitos e princípios estabelecidos como norteadores da proposta pedagógica da instituição. Percebe-se um número significativo de ações de extensão desenvolvidas em parceria com outros colaboradores, internos e externos à universidade. Entretanto, há que se garantir meios para a aproximação e ampliação do diálogo da escola com os demais segmentos da universidade, bem como, maior investimento em recursos humanos, materiais e tecnológicos visando a plena realização do tripé acadêmico e do direito das crianças a uma experiência educativa de qualidade.

Published: August 2022

A falta de guarda responsável e a presença de cães na rua expõe a população a agressões provocadas por cães, como mordidas, que, além do trauma físico e psicológico, podem carrear patógenos. A problemática da presença de cães ao redor da escola preocupava a direção, professores, pais e responsáveis de uma escola em Araucária (PR). Desta forma, por meio de reuniões entre a direção da escola, a equipe do projeto de extensão e a médica veterinária da prefeitura da cidade, uma atividade educativa foi criada para abordar o assunto. O teatro e uma atividade manual foram utilizados como recurso de ensino interativo, interdisciplinar e dinâmico. O objetivo foi conscientizar sobre as possíveis causas de mordidas, como preveni-las, e ensinar a higienização básica da lesão, além de cuidados imediatos em eventual mordedura por cão. A única personagem da peça foi criada e representada por uma acadêmica de Medicina, uma cachorrinha batizada de “Esfirra”. Em um dia de intervenção, 145 estudantes participaram, de forma ativa e participativa. O questionário aplicado aos professores da escola, com intuito de avaliar a atividade educativa, revelou, pela percepção dos educadores, ser uma atividade lúdica, cativante, trouxe informações úteis e importantes, com linguagem clara e empolgante, abordando um tema da realidade das crianças da região. Além da interdisciplinaridade, a troca de saberes e o aprendizado dos integrantes do projeto foram imensuráveis, contribuindo para seu crescimento profissional e cidadão.

O padrão de desenvolvimento econômico atual tem aumentado significativamente o consumo dos recursos naturais e, por conseguinte, a geração de resíduos. Os resíduos químicos domésticos e, em particular, os óleos residuais de fritura, têm tido um papel de destaque nesta problemática em razão do grande volume descartado na natureza. Por conta disso, ações de Educação Ambiental que promovam o reuso de óleos residuais de fritura podem desenvolver mecanismos importantes de atenuação do impacto ambiental de médio a longo prazo. Em linha com essa estratégia, a produção de sabões, tintas e velas ecológicas com qualidade e segurança, a partir de óleos residuais de fritura, podem oportunizar o desenvolvimento e a promoção de projetos de extensão universitária relacionados à temática de Educação Ambiental de reuso de resíduos. Nesse sentido, este trabalho descreve um relato de experiência das ações de extensão universitária desta natureza desenvolvidas pelo projeto Cicla-Óleo UFPB em escolas públicas da região metropolitana de João Pessoa (PB, Brasil) e seu entorno.

Guatemala Makes COVID-19 the Responsibility of the People
Authors: Carosella Elizabeth
Published: August 2022

It’s a muggy August evening and a thundershower is forming over the hilly treescape that frames Guatemala City’s urban center. I am rushing home from the supermarket, hoping to beat the storm. I’ve lived in Guatemala since 2018, though, recently, going to the supermarket is the only time I leave my apartment, as COVID-19 cases rise across the country. Driving through the city, neon-lit signs flicker on for restaurants and cafes that had, at one point, been under nationally mandated closure. At a stop light, I get a clear view into a well-known restaurant that had been one of my favorites, pre-COVID. Several clusters of people are seated inside a closed indoor space. None of them are wearing masks- a dramatic shift in the panorama from just months ago.

Financial risk assessment of six regions in China under the TOPSIS model based on a coupling perspective
Authors: Ding Yizhe , Chen Keyu
Published: August 2022

As China's economy enters a new normal, the economy gradually changes from high speed to high quality, and the task of resolving various types of risks in each region becomes more arduous, while the prevention and control of regional financial risks will certainly become one of the severe challenges faced under the new economic normal. Based on the parallel data of six regions in China, this paper combines EWM subjective weights and AHP objective weights to construct EWM-AHP coupling weights. It also adopts the distance between ideal point superiority and inferiority solution (TOPSIS) ranking method to quantify the relative relationship between the sample and the evaluation criteria and establishes a differentiated financial risk indicator model for the six regions. The results show that the financial risk is lower in regions with a weaker economic base and lower level of financial development. Financial risk is higher in regions with a higher degree of financial openness. The integrated EWM-AHP and TOPSIS models can effectively reduce the financial risks in the development process of the six regions and improve the smoothness of economic operation, which has a particular application value. The results show that the financial risk is higher in regions with more backward economic development, and the financial risk index is lower in regions with sound capital market development.

In recent years, with the promotion of carbon peak and neutrality policy, the issue of environmental, social and governance (ESG) information disclosure has become a hot topic of common concern to all sectors of society. Through the study of the conflict mechanism in ESG information disclosure, it can help decision makers choose a solution which can be accepted by others and help them develop. By implementing the Graph Model for Conflict Resolution (GMCR), we construct a conflict model for governments, enterprises, financial institutions and investors in the ESG information disclosure. GMCR can conduct stability analysis based on their preferences, and reach equilibrium results so as to provide a worthy reference plan for multiple parties and build a coordinated development mechanism in which they can rely on and promote each other.
Prediction and Clustering of Bank Customer Churn Based on XGBoost and K-means
Authors: Zhang Tiansheng
Published: August 2022

Due to the fierce competition of commercial banks, customers are becoming more and more important to banks. Therefore, customer churn has become a major problem that banks need to face. In this paper, XGboost algorithm was used on a data set of customers of a US bank from Kaggle to predict customer churn, and grid search method was used to find the best hyperparameters. Moreover, K-means algorithm is adopted to further subdivide the lost customers. For predicting customer churn, XGBoost algorithm achieves 0.84 in accuracy, 0.83 in precision, 0.84 in recall and 0.84 in F1 score on the test set. And the most important score for features in the case of the algorithm adopted are customers' estimated salary, credit score and balance. For the segmentation of churn customers, K-means algorithm divides these customers into 5 groups. These five groups of customers have different values for banks, so this paper puts forward corresponding recovery suggestions for their respective characteristics

Authors: Han Yi , Jin Ding , Luo Shuyuan
Published: August 2022

Homelessness is fast becoming one of the most troublesome issues in United States (U.S.) in terms of the uprising total number of homeless population and potential social instability that it may cause. In previous studies, efforts mainly focused on the characteristics of specific subgroups out of the overall homeless. In this paper, more attention is paid to determine major factors related to homelessness in U.S. using correlation and a model is proposed to predict the tendency of change in the total number for homeless population for each state in U.S. by applying advanced machine learning method of Long Short-Term Memory (LSTM). The study suggests that each state would be primarily troubled by homeless subgroups with different characteristics. Its results also imply that crime rates may relate to with the trend of change in total homeless population and the dominant concerns regarding to the categories of crime differ on a state basis. The study further suggests that after optimization, the LSTM model with interpolation or with multi-dimensions are the best approaches to predict the overall change in the number of homeless populations for each state in the U.S.

Authors: Tang Wenxin , Li Peiyao , Wang Bonan
Published: August 2022

This paper studies the raw material ordering and transportation strategy based on the principle of integer programming. Based on the production data of a certain enterprise, the original attachment data is firstly analyzed, 6 indicators are selected and the weight coefficient of each indicator is determined by the TOPSIS entropy weight method. Then, a 0-1 integer programming model for solving the minimum number of suppliers is established, and the most economical ordering scheme model is established with the least comprehensive cost as the objective function. Finally, taking the minimum transshipment loss as the goal and the transporter's carrying capacity as the constraint condition, the transshipment plan is solved by the greedy algorithm. After analyzing the ordering plan and the transshipment plan, the ordering plan can meet the weekly production demand, and the average weekly inventory is 59540 cubic meters, the mean square error is 222.67 cubic meters; the average loss of the transshipment scheme is 8.33%, and the ratio of suppliers with two or more transshipments to the total suppliers is 3.85%.
How to allocate portfolio weight based on the FF3F model
Authors: Gao Jingyuan , Yang Qinyu
Published: August 2022

Selecting the correct stocks and funds is essential for portfolio management and allocation. In order to reduce the risk of the portfolio, it is better to diversify the assets and select the stocks within more than one sector. Another step would be setting the portfolio with the firefighter case or without it. The firefighter case illustrates that we suppose there is a firefighter who has 25 years of service as a firefighter who will be retired in Florida. The Florida government gives the retired firefighter two choices. He takes the lump-sum payout and invests his nest egg and the lump sum in supporting him throughout his retirement. Another one is that he takes the pension benefit and invests his nest egg in supplementing the pension benefit. In this case, we compared those two and finally selected the one in which he maintained the pension and made the pension weight precisely equal to 71%. The Sharpe ratio for this scenario is relatively higher than the another. Moreover, choosing the correct financial model. Comparing the pros and cons between the CAPM model and the Fama French Three-Factor model, we found that the Fama French Three-Factor model is more related to reality and includes the market risk, making the portfolios more accurate and reliable.

The price of crude oil soared after the outbreak of the Russia-Ukraine conflict. However, China's stock market, by contrast, continues to fall. This paper studies the impact of crude oil price on the dynamic of China’s stock market. We build an ARMAX model and an ARMA-GARCH model to analyze whether there are connections between crude oil price and China’s stock market. This paper finds that the crude oil futures rate of return is positively correlated with the Shenzhen Component index rate of return and Shanghai Component index rate of return. Also, the crude oil price has a significant impact on the fluctuation of the Shenzhen and Shanghai Stock Exchanges.

Published: August 2022

As the necessities of production and life, construction and plate have always played an important role in China's national economy. It is also an important industry affecting China's economic development. The unit price of raw materials and the cost of transportation and storage have always been the main expenses of enterprises. Therefore, it is particularly important to study how to reduce the ordering cost and transshipment cost of raw materials. This paper makes a quantitative analysis on the supply characteristics of 402 suppliers. According to the supply quantity of suppliers, the orders with an order quantity of 0 are excluded, so as to extract the variance, range and real average value of each supplier's orders in five years. The difference between the enterprise's order quantity and the supplier's supply quantity is extracted, so that they represent four indicators: supplier reliability, sustainability and stability, And the supply intensity of the supplier. After the data is normalized through AHP, the weight of the index is assigned, the index is weighted in combination with TOPSIS, and finally the score is calculated. Then, the 0-1 programming model is established. The coefficient of the objective function is the maximum supply of each supplier every week. After analysis, it is concluded that the maximum supply is two-thirds of the average value plus one-third of the maximum value. The constraint conditions are established so that the sum of the supply of the selected suppliers is greater than the weekly capacity required by the enterprise. The 240 weeks are divided into five years. Considering the influence of practical factors, when predicting the supply of suppliers in the next 24 weeks, only the first half of each year is selected, and the grey prediction method is used to predict the average weekly supply of each supplier in the next 24 weeks. After the prediction, the grey prediction of the existing data is not ideal, and the BP neural network is used to re predict this kind of data. After the prediction, a multi-objective programming model is established to ensure the minimum sum of ordering cost and transshipment cost. Under this scheme, the minimum supply corresponding to a, B and C is calculated.
PEST Analysis Based on Japan's Nuclear Wastewater Discharge Event
Authors: Yang Kexin
Published: August 2022

On April 13, 2021, the Japanese government officially issued a statement saying that it will discharge the nuclear waste water stored in the Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Plant into the sea around the spring of 2023 for a period of 30 years. Despite almost overwhelming opposition domestic and abroad, the Japanese government has not withdrawn or delayed the plan. Based on the six stakeholders and the PEST analysis method, this paper deeply discusses the reasons for the Japanese government's unilateral decision to discharge nuclear waste water into the sea. Research shows that Japan's discharge of nuclear waste water is not just an environmental protection issue, it is a consequence of Japan's political, economic, technological, cultural and even historical factors. The purpose of this paper is to provide a reference for effective measures in the future, in the hope of better protecting the legitimate rights and interests of stakeholders by introducing international environmental law to prevent and postpone the discharge of nuclear wastewater from Japan.

Based on the scenario of supply chain relationship, this paper selects companies that continuously disclose information on targeted poverty alleviation from 2016 to 2020, and establishes a two-way fixed effect model to explore the impact of targeted poverty alleviation on supply chain relationships. The study found that the scale of targeted poverty alleviation by enterprises will reduce the concentration of suppliers/customers, and at the same time reduce the level of commercial credit to improve the financing constraints of enterprises, and ultimately reduce the risk of enterprise supply chain. The government-led market-oriented poverty alleviation mechanism not only brings positive benefits to the society and the public, but also helps enterprises reduce risks in the dimension of supply chain relationships and achieve the dual pursuit of social responsibility and economic goals.

Problems on LGBT Communities’ Medical Insurance and Constructing Research of the Solution
Authors: Wang Jiayi
Published: August 2022

As a minority, the LGBT community has always received severe discrimination in medical cases. The government hasn’t constructed a complete healthcare system, and the community hasn’t received the respect and rights they deserve when receiving treatment. This has caused the LGBT community’s health status to be way lower than the heterosexual community. As a part of society, the LGBT community needs to be accepted and helped when they receive this kind of discrimination. We also need to construct and perfect a complete healthcare system for them. For the construction of the policy, this paper used literature analysis and content analysis methods. The source of these problems is the government’s lack of attention to the LGBT community, their social discrimination, and the lack of medical resources. The result of the analysis is to establish community health centers for the community, and the government should establish relevant laws for the LGBT community’s rights and medical insurance. This policy research has promoted the improvement of the rights of the LGBT community, but there is no more specific research due to a lack of primary data.
