Shear transfer strength estimation of concrete elements using generalized artificial neural network models
Authors: Zayan Hend S. , Mahmoud Akram S. , Hamdullah Dhifaf N.
Published: February 2023

Based on published test findings, this article outlines the use of artificial neural networks (ANNs) to forecast the efficiency factor of shear transfer strength in concrete. Backpropagation neural networks with feed-forward have been employed. The ANN model was created by incorporating a huge experimental database and carefully selecting the architecture and training procedure. The presented ANN model offered a more accurate tool to compute R (where R is a measure of the closeness of association of the points in a scatterplot to a linear regression line based on those points) and capture the impacts of five primary parameters: concrete compressive strength, steel reinforcement ratio, steel yield strength, fiber volumetric ration, and steel fiber aspect ratio are given from experimental data. The obtained results reveal that the first important parameter is concrete compressive strength. In addition, ρ

parameter represents the normalized tensile force in steel reinforcements of section, whereas the smallest importance parameter L/D is aspect ratio of steel fibers. Also, the current study illustrated the facilities of using generalized artificial neural networks on predicting the shear transfer strength across the concrete sections, whether they are fibrous or not. From the results, the correlation factor (R
2) is estimated to be about 83%, which means it had a good correlation within the input parameters. In addition, the mean absolute percentage error was 2.06.
Augmenting adjusted plus-minus in soccer with FIFA ratings
Authors: Matano Francesca , Richardson Lee , Pospisil Taylor , Politsch Collin A. , Qin Jining
Published: February 2023

Adjusted plus-minus (APM) can sometimes lack common sense. This happens, for instance, when mediocre players move into the top ten, and superstars fall out of the top 100. These occasional outliers hurt the credibility of APM, and mask the benefits, such as increased prediction accuracy. We address this problem with a new method, called Augmented APM. Augmented APM incorporates external player ratings into APM methodology. The purpose of the external rating system is to capture common sense player value. Augmented APM maintains the benefits of APM, and improves credibility by leveraging external ratings that pass the eye test. The key technical idea is recasting APM into a Bayesian framework and using external ratings in the prior distribution. This paper instantiates the Augmented APM method by applying it to soccer. APM methods have not had a substantial impact on soccer, because soccer matches are low scoring, with a low number of substitutions. For external ratings, we use the video game FIFA, which provides subjective evaluations from thousands of scouts, coaches, and season ticket holders. Our paper shows that Augmented APM predicts match outcomes better than (1) APM, and (2) FIFA ratings. We also show that Augmented APM de-correlates players on the same team, which helps for players that play most of their minutes together. Although our results are specific to soccer and FIFA ratings, Augmented APM is a principled method to combine subjective and objective ratings into a single system.

New perspectives on the early cities and states in Mesoamerica
Authors: Huster Angela
Published: February 2023

The two edited volumes reviewed here provide up-to-date overviews of their respective topics in Mesoamerican archaeology: the development of the early cities in the region (Early Mesoamerican cities) and the ways in which one such city grew to influence or control a large portion of the region (Teotihuacan and Early Classic Mesoamerica). Both volumes were developed from SAA (Society for American Archaeology) conference sessions and—for better or worse—this remains evident in their internal variability in the definition of key terms and the lines of evidence presented in different chapters. Both focus on identifying and discussing the processes behind observed phenomena, rather than binary determinations of whether a given case was or was not a city, state or empire. Most of the chapters in both volumes also include significant quantities of data generated over the past 10–15 years, which provide important updates to traditional narratives. In the case of Cities, the influx of new data is largely driven by the explosive potential of LiDAR to identify landscape-level settlement patterns in lowland portions of Mesoamerica, and the resulting chapters are biased toward lowland cases. In Teotihuacan, much of the new information comes from a majority-Mexican list of authors, who work at sites in a broad range of locations across the country. Both volumes deftly avoid rehashing what have historically been the most visible debates on each of their topics: the Olmec mother/sister culture debate and the nature of Teotihuacan/Maya interaction, respectively.
βHB inhibits glucose-induced GLP-1 secretion in GLUTag and human jejunal enteroids
Authors: Elebring Erik , Casselbrant Anna , Persson Sara M T , Fändriks Lars , Wallenius Ville
Published: February 2023

Ingestion of nutrients stimulates incretin secretion from enteroendocrine cells (EECs) of the epithelial layer of the gut. Glucagon-like peptide-1 (GLP-1) is one of these incretins that stimulate postprandial insulin release and signal satiety to the brain. Understanding the regulation of incretin secretion might open up new therapeutic options for obesity and type-2 diabetes mellitus. To investigate the inhibitory effect of the ketone body β-hydroxybutyrate (βHB) on glucose-induced GLP-1 secretion from EECs, in vitro cultures of murine GLUTag cells and differentiated human jejunal enteroid monolayers were stimulated with glucose to induce GLP-1 secretion. The effect of βHB on GLP-1 secretion was studied using ELISA and ECLIA methods. GLUTag cells stimulated with glucose and βHB were analysed using global proteomics focusing on cellular signalling pathways and the results were verified by Western blot. Results demonstrated βHB had a significant inhibitory effect on glucose-induced GLP-1 secretion at a dose of 100 mM in GLUTag cells. In differentiated human jejunal enteroid monolayers, glucose-induced secretion of GLP-1 was inhibited at a much lower dose of 10 mM βHB. The addition of βHB to GLUTag cells resulted in decreased phosphorylation of kinase AKT and transcription factor STAT3 and also influenced the expressions of signalling molecule IRS-2, kinase DGKε and receptor FFAR3. In conclusion, βHB displays an inhibitory effect on glucose-induced GLP-1 secretion in vitro in GLUTag cells and in differentiated human jejunal enteroid monolayers. This effect may be mediated through multiple downstream mediators of G-protein coupled receptor activation, such as PI3K signalling.
Modelling asthma development in a population with genetic risk and polluted environment
Authors: Kirenga Betty K. Nabiyonga , Kitayimbwa John M. , Mugisha Joseph Y.T.
Published: February 2023

Environmental pollutant continues to pose a great threat to public health, leading to development of chronic diseases. In this study, a nonlinear mathematical model is formulated and analysed to study the effect of genetic risk, environmental pollutant, public health education/awareness on asthma development. Conditions for the existence of the unique positive steady state and permanence of the system are assessed. Using Lyapunov function analysis, the unique positive steady state is locally and globally asymptotically stable. Results reveal that genetic risk, pollutant emission rate, effective exposure rate of population to polluted environment and recurrence rate contribute to asthma prevalence. However, sufficiently effective pollutant reduction strategies, improvement in compliance to public health education/awareness together with human dependent environmental pollutant depletion lead to a marked reduction in disease prevalence.

Phylogeography of the Western Populations of Stylodipus telum (Rodentia, Dipodidae) based on Mitochondrial DNA
Authors: Rusin M.
Published: February 2023

The phylogeographic analysis of Stylodipus telum was performed based on cytochrome b mitochondrial gene. Two westernmost subspecies, S.t. falzfeini and S.t. turovi, both formed independent monophyletic clades, but the genetic distance between them clearly indicates that neither should be treated as a separate species. Individuals from remote populations of S.t. falzfeini mix together and do not have a clear phylogeographic structure, which could indicate a recent panmixia within the subspecies. Populations in Kherson Region are under threat due to the ongoing Russian invasion.
The Importance of Artificial Wetlands in the Conservation of Wetland Birds and the Impact of Land Use Attributes Around the Wetlands: a Study from the Ajara Conservation Reserve, Western Ghats, India
Authors: Patil S. , Choudaj K.
Published: February 2023

Artificial wetlands are built to meet the rising human population's water needs, with little attention paid to their ecological significance. The current study was carried out to assess the importance of artificial wetlands in biodiversity conservation. Habitat quality of wetlands was assessed using the birds as an ecological indicator. Bird surveys were carried out at the five artificial wetlands located in the Ajara conservation reserve, northern Western Ghats, India. Bird surveys were conducted for five years (2011–2015). During the study, 165 bird species were recorded, including 34 wetland birds and 131 wetland-associated birds. Wetlands in forested areas have a higher richness of wetland birds. Wetlands surrounded by exotic plantations, agriculture, and human settlements exhibit lower wetland bird richness than wetlands in forested areas. Land use attributes around the wetlands affect wetland bird diversity. The current study gives a glimpse that these artificial wetlands could serve as a possible habitat for wetland birds.

Abstrak: Artikel ini mendeskripsikan salah satu diskursus dari filsafat al-Qur’an, yaitu eskatologi yang dilihat berdasarkan pemikiran keislaman Fazlur Rahman (1919-1988). Khususnya mengenai hari kebangkitan, surga dan neraka.

Moment of truth ini terjadi setelah fenomena kehancuran bumi, meskipun menurut Rahman, pernyataan filosofis al-Qur’an tidak lah membicarakan kehancuran bumi secara total, melainkan membicarakan transformasinya kepada wujud baru yang secara wajar dan otomatis meniscayakan kehancuran wujud lama. Dan secara otomatis, bagi Rahman, tidak lah dibenarkan jika surga bagi para muttaqin, dan neraka bagi para orang jahat itu sudah ada sejak sekarang, melainkan keduanya masih sedang menunggu adanya proses perubahan transformasi sampai tiba saatnya. Yang oleh al-Qur’an disebut dengan hari kebangkitan. Pada moment hari kebangkitan ini, Rahman juga meyakini bahwa jiwa dan raga merupakan satu paket sebagai diri seseorang yang akan tersusun dan wujud kembali. Tentu saja hal ini berbeda dengan pernyataan para filosof dan teolog Muslim lainnya yang masih mempersepsi dualisme antara jiwa dan raga, yang sejatinya menurut Rahman satu paket menjadi identitas diri manusia.Kata Kunci: Fazlur Rahman, Hari Kebangkitan, Surga-Neraka.

Said Aqil Siroj Merupakan cendekiawan muslim yang tegas mendorong terciptanya bangsa pluralis humanis. Titik tolak pemikirannya tentang hakikat persatuan salah satunya tertuang dalam pemahaman akan humanisme. Pemikiran humanisme memiliki dimensi yang luas. Konteks kerangka nilai-nilai Islam secara terang dia ungkapkan sebagai pokok bahwa sejatinya Islam menyediakan panduan secara tegas tentang perlindungan dan terciptanya perdamaian secara kolektif. Sudah tentu, secara khusus pemikiran Said Aqil Siroj menegaskan bahwa humanisme religius akan menegaskan rasa tanggung jawab lebih luas dan tidak sekerdar fokus dalam mendapatkan kebebasan sebagaimana humanisme dipahami oleh barat. Humanisme religius meberikan dan melahirkan sikap untuk melakukan koreksi etik setiap manusia dalam menjalani kehidupannya. Pemikiran Said Aqil Siroj tentang humanisme Islam menguatkan tentang moralitas Islam dan persaudaraan seiman. Dalam konsep moral dalam Islam yang dimaksudkan oleh Said Aqil Siroj, bahwa moral yang dijalankan oleh setiap manusia bagaimana menengahkan antara kebebasan dirinya dan bagaimana kebebasan yang digantungkan kepada etika agama. Terkait persaudaraan seiman Said Aqil Siroj pada intinya memandang agama berperan mengarahkan manusia untuk selalu mengemban nilai-nilai harmonis, maka seseorang yang beragama berarti dalam jiwanya telah berkembang nilai-nilai harmoni dan kasih sayang sebagai bekal untuk hidup ditengah masyarakat.

Effects of nourishing qi, activating blood circulation, and inducing resuscitation on nerve cell pyroptosis after cerebral ischemia-reperfusion
Authors: Liu Lin-Quan , Huang Xiao-Ping , Cai Ya-Hong , She Yan , Deng Chang-Qing
Published: February 2023

Cerebral ischemia-reperfusion (CIR) is a serious complication often associated with cerebral ischemia. The purpose of this study was to explore the therapeutic effect of nourishing qi, activating blood circulation, and inducing resuscitation (Borneol with astragaloside IV and Panax notoginseng total saponins, BAP) on CIR. Neurological function score system was used to determine the neurological function. The survival of nerve cells was detected by Nissl staining. The levels of IL-1β, IL-18, IL-4, and IL-10 were detected by ELISA. The expression of GSDMD, GSDMD-N, Nrf2, and HO-1 proteins in hippocampus tissues was measured by immunohistochemistry (IHC). Western blot, RT-qPCR, or immunofluorescence (IF) were used to detect the NACHT, LRR, and PYD domains-containing protein 3 (NLRP3), pro-Caspase-1, Caspase-1, Nrf2, and HO-1 expression. Lactate dehydrogenase (LDH) level was analyzed by LDH release assay. Cell viability was determined by cell counting kit-8 (CCK8). Apoptosis was detected by flow cytometry. BAP significantly promoted the recovery of nerve function, the activity of nerve cells, and the expression of Nrf2, HO-1, IL-4, and IL-10 in rat hippocampus tissues after CIR. BAP has an obvious inhibitory effect on the expression of NLRP3, pro-Caspase-1, and Caspase-1 proteins, the release of IL-1β and IL-18 factors, and neuronal pyroptosis in hippocampal tissues. BAP also promoted IL-4 and IL-10 levels, and the activity of SH-SY5Y cells. The IL-1β, IL-18, NLRP3, pro-Caspase-1, Caspase-1, GSDMD, and GSDMD-N expressions were significantly inhibited by BAP in vitro, which was reversed by Nrf2 knockdown. This study confirmed that BAP alleviated rat CIR and inhibited the pyroptosis of SH-SY5Y cells by regulating the Nrf2/HO-1 signaling pathway. This study provided new directions and ideas for the treatment of CIR.

The article examines the transformation of social practices of using mobile phones by students. Two areas of manifestation of social practices were the focus of the authors' research: the daily life of students and the learning process. The article provides an overview of the works of foreign and domestic authors who have made a significant contribution to the study of the transformation of social practices of using mobile phones in everyday life. The methodological basis of the article is the theory of media as a continuation of M. McLuhan's man, which is supplemented by the constructivist theories of I. Hoffman, P. Berger, T. Lukman, which made it possible to trace the transformation of social practices of using mobile phones. Social practices are daily actions and routine actions that do not require explanation, performed in a familiar way in everyday life. The research method was the focus group (N=32), the informants were students of Volgograd State University; the time of the study: December 2021 – March 2022. The study allowed us to conclude: the first mobile phones performed the function of movement control, were used as toys, initiating individual and group gaming practices. The presence/ absence of a modern game or a phone model made it possible to use power resources, move through the steps of the social hierarchy in the school team. Currently, students use mobile phones for oral communication, but visual and written communication practices are no less popular. The usual social practice using a smartphone is listening to music, communicating on social networks and messengers, sending messages, watching videos. Modern mobile phone applications allow you to turn it into a professional earning tool, facilitate everyday life, accompany the learning process. A modern mobile phone has become a "part of a person", to forget it is to lose touch with the world. The presence of a smartphone is perceived as a necessity for everyday life, leisure, work and education. A special style of communication has developed among students, unthinkable without the use of modern telecommunication means, namely a smartphone.
An assessment of wounds caused by the attachment of remote sensing tags to North Atlantic right whales (Eubalaena Glacialis): 1988 - 1997
Authors: Quinn Cathy A. , Hamilton Philip K. , Kraus Scott D. , Slay Christopher K.
Published: February 2023

Because of the increase in usage of remote sensing tags to track the migration and movements of cetaceans, it has become increasingly important to assess the impact of such techniques on the target species. Between 1988 and 1997, 55 tags (41 satellite telemetry, 14 VHF or acoustic radio transmitter) were attached to 49 North Atlantic right whales (Eubalaena glacialis). All tags had implantable barbs or were fully implanted below the dermis. Right whales are photographically identifiable and the New England Aquarium curates the North Atlantic catalog, which currently numbers 374 individuals. The photo catalog has made it possible for tagged individuals to be tracked after the tag falls off the whale. Photo documentation during and after tagging provides an opportunity to monitor physiological effects from tags and healing responses to tags.
IMPLEMENTAÇÃO DO ESPORTE UNIVERSITÁRIO: INTERAÇÃO ENTRE UNIVERSIDADE E INSTITUIÇÃO FEDERATIVA
Authors: DOS SANTOS ERASMO BRAZ
Published: February 2023

A implementação é uma instância de execução de uma política pública. E o esporte garantido constitucionalmente é um dos temas legítimos nesta instância. A universidade pública pertencente à burocracia estatal, é um locus de desenvolvimento deste tema. O objetivo do trabalho foi analisar as interações entre uma universidade pública e uma instituição federativa estadual universitária na implementação do esporte. Abordou-se ótica neoinstitucionalista histórica para qual as instituições formais e informais importam e são centrais junto com os atores na discussão de políticas públicas. As categorias elegidas da implementação foram contexto organizacional, político e social. Na metodologia foi utilizada a pesquisa documental e a técnica de análise de conteúdo. Nos resultados a interação entre a universidade e a instituição federativa foi fundamental para a participação da universidade nos eventos promovidos nos níveis subnacional e nacional. O gestor esportivo (burocrata estatal) da universidade, foi o ator que mais promoveu a interação com a entidade federativa. Porém, no que tange as categorias contexto organizacional, político e social da implementação, essa interação se mostrou precária. Considerou-se que ocorreu precariedade na interação nas instituições formais e informais pesquisadas no sentido consignar robustez ao esporte universitário mato-grossense, estando basicamente centrada na participação de eventos esportivos promovidos em níveis subnacional e nacional não adentrando nos aspectos da implementação.

A series of solid polymer electrolyte films, employing 49% poly(methyl methacrylate)(PMMA)-grafted natural rubber (MG49) as polymer host and lithium tertrafluoroborate (LiBF4) as conducting material were prepared by solution casting technique. The films of MG49-LiBF4, MG49-PMMA and MG49-Poly(vinylidene fluoride-co-hexafluoropropylene)(PVDF-HFP) at the optimum weight percentage of LiBF4 (25 wt.%, 25 wt.% and 30 wt.%) respectively, were characterized using potentiostatic electrochemical impedance spectroscopy (EIS) technique to measure their impedans. The measurements were conducted at the temperature range from 303 K to 403 K. The values of dielectric constant, Ꜫr increases with the increase of ionic conductivity. The dielectric constant, Ꜫr and dielectric loss, Ꜫi decrease with increase in frequency at the low frequency region attributed to the electrode polarization effects, but almost negligible in the high frequency region due to frequency independent. The imaginary part, Mi of electrical modulus are observed increases with frequency. The systems are concluded as ionic conductors by the present of Mi peak in the plot Mi versus frequency. The presence of peaks at certain frequency in the tan δ versus frequency plots of the polymer electrolytes indicate the existence of relaxation of charge in all samples contributed by the ions and polar functional groups.
First World War diary of Ernst Jünger and äWorker: Emotion of Fear and Expansive Subjectivity
Authors:   The Korean Society For German History, Kim Hakie
Published: February 2023

This essay tries to present alternative interpretations of the works, which Ernst Jünger Scholars wort during the Weimar Republic, based on an analyzing his First World War diary. I found in his diary some symptoms of the war neurosis and identified the most frequently uttered emotion, “unhomely(unheimlich)”. I interpreted the findings as indicator for his failure to assign the war experiences cultural and hisotrical meanings and to integrate his experiences into a coherent narrative and an healthy self. This failure was reiterated in his famous novel In Storms of Steel. His comrades community of soldiers war just a vacant formula while soldiers were presented as images based on the bourgeoisie value and emotion of honour. Although he successfully embodied the front generation as a “New Race” in War as an inner Experience of 1922, solipsistic nature of the subject hardly disappeared. Even in The Worker: Dominion and Form the bourgeoisie figure repeated itself. Ernst Jünger is to be interpreted as a nihilistic, voluntaristic, actionist, violent bastard version of liberalism.
The Mood and Physical Activity of the Tibetan and Han University Students During the COVID-19
Authors: Zhang Liqiang , Huina Gao
Published: February 2023

This study aimed at exploring a relation between the mood state and physical activity (PA) among the Zang and Han university
students during the COVID-19. 2382 university students in Shaanxi, Tibet, Hubei and Guizhou were recruited using a convenient
sampling method to participate in this study. Independent samples t-test and ANOVA were used to compare the differences of the
mood state of the college students by gender, grade, and ethnicity respectively. Pearson correlation and stepwise linear
regression were conducted to examine the indicators’ relations. The results indicated that there was statistical significance
in the mood state among the ethnicity, gender, and grade (p < 0.05). The total emotional score tended to increase as the
grade increased; There are statistical significance in PA between gender, and grade (p < 0.05), while PA declining as the
grade increased. However, there was no statistically significant relationship between grade and positive affect (p > 0.05).
There are statistically significances between all other indicators (p < 0.05). The study shows that COVID-19 suppressed
mood state and participation in PA among Tibetan-Han college students. PA is better for increasing mood state of the university
students, which is better for positive emotion, but bad for negative emotion as the grade rises.

Firefighters are often exposed to traumatic events such as high temperatures, heavy fumes, and toxic gases during rescue services.
The challenges require firefighters to have a higher level of physical performance compared to a typical person. In urbanized settings,
weight-bearing staging is a necessary skill for firefighters. Currently, research has found a positive correlation between firefighter
body composition and occupational activity performance. This study aims to examine effects of body composition on the weight-bearing
staging performance of firefighters, providing guidance for firefighters' daily training routines. Participants were 47 male firefighters
in Yangjiang City, Guangdong Province (age: 25.2 ± 3.9; height: 169.8 ± 5.1cm; 68.9 ± 8.0kg; 24.2 ± 2.4kg / m2). Load climbing tests were
organized by the fire rescue brigade in Yangjiang City. The tested wore a full set of fire protective clothing, carried a positive pressure
air respirator and carried two water belts (with a total load of 30kg), climb to a 10-story building and record the test completion time
by manual timing. For body compositions, body weight, body fat, skeletal muscle content and lean weight were measured by machine with the
help of Inbody 360 body composition tester. Linear and PLS regressions were used for data analysis. In the Gray's association degree
analysis, the association degree of the weight indicators was ranked first, meaning that weight had the strongest association with
weight-bearing indoor performance. In linear regression analysis, the model equation was derived as follows: weight-bearing floor
performance (s) = 16.20 + 0.9056 * weight (kg), and the R-square of the model was 0.1927, implying that body weight could explain
19.27% of the variance in weight-bearing floor performance. An F-test of the linear model yielded F = 10.74, P < 0.05. In the PLS
regression analysis, the principal component of 1 was the optimal number of extractions from the projection importance index VIP value,
and the final result was that the regression of weight and body fat on weight-bearing dengue performance had a significant effect.
Based on the results, the highest association emerged between weight and weight-bearing performance; weight had a significant
effect on the weight-bearing performance, with greater weight-bearing sitting time; weight and body fat had significant effects on
weight-bearing staging performance. To maintain adequate occupational mobility, firefighters are recommended to manage body
composition through aerobic endurance and strength training.

The purpose of this study was to explore the quality of community sports distribution service through the evaluation and satisfaction of the elderly in Yangpu District of Shanghai on the quality of community sports service and explore the relationship between the quality of community sports distribution service, satisfaction, and behavioral intention. Data were collected by using surveys and analyzed using mathematical statistics. The survey refers to SERVPERF model to design a six-dimension, intermediary variable satisfaction and behavioral intention five-point scale for the service quality of community sports distribution. The sample size was 261. SPSS25.0 was used to conduct data analysis. Reliability and validity test and correlation analysis of service quality and satisfaction and behavior intention of the elderly were conducted. The Cronbach's Alpha value of the scale was 0.932. The KMO value was above 0.8, and Bartlett sphericity test was significant, indicating high reliability and validity of the scale. The analysis results showed that the mean values of the six dimensions of service quality and satisfaction were higher than 4.2, indicating that the elderly had a high evaluation of community sports distribution service quality. Community sports service delivery service quality dimensions and satisfaction and behavior intention between different degree of correlation, in addition to the tangibility of community sports service reliability of distribution service quality, responsiveness, assurance, empathy, and practicality for older people to participate in community sports service satisfaction and behavior intention of distribution had significant positive correlations. More women than men participated in community sports service delivery among the elderly since most of the delivery items are dance and martial arts. The elderly had a good participation in community sports service distribution, with the frequency and duration of weekly participation basically meeting the requirements of China's sports population within 4-5 years. They had more than 30 minutes of moderate intensity training at least three times a week. According to the evaluation and satisfaction of the elderly on the service quality of community sports service delivery, community sports service delivery was of high service quality. The service quality of community sports service delivery had a positive impact on the sustainability of elderly people's participation in community sports service delivery, and they were willing to recommend it to people around them to participate. Community sports service distribution activities should be publicized and promoted on the Internet so that more people can participate in the willingness.

In China, graduate students are facing heavy pressure from study, work and life. In order to change this situation, many colleges and universities have set up PE elective courses, but the proportion of elective courses is generally low, and the health status of students has not been fundamentally improved. The purpose of this study is to investigate the current situation and motivation of Postgraduates' physical exercise, and explore ways to attract more postgraduates to participate in physical exercise and promote their health. The study mainly adopts the methods of experiment and questionnaire. Two classes of students who chose PE elective courses are selected as the experimental objects. Students in Experimental class were given motivation stimulation, while another class were not. Sports stimulation includes combing family health history, inculcating the role through cases, monitoring students' physique, etc. The two classes had same exercise time (once a week, 90 minutes each time), same exercise method (intermittent cycle training for 16 weeks). In addition, this study uses Professor Chen Shanping's sports motivation scale to conduct a questionnaire survey on the graduate students participating in the experiment. Pearson analysis method in SPSS software was conducted to analyze the correlation between sports motivation and sports behavior. The students in the experimental class exercise better after class than those in the control class. Girls' physical and social motivation of physical exercise is much higher than boys, while boys' ability and motivation of physical exercise are significantly higher than boys. Different physical exercise motives have significant effects on physical exercise methods and physical exercise frequency. It is concluded that motivation stimulation is conducive to the formation of exercise behavior and there is a positive correlation between physical exercise motivation and physical exercise behavior.

The purpose of this paper was to analyze the changes of college students' physical health and the relevant influencing factors, and
provide the basis for the school to formulate reasonable measures to improve students' physical health. A total of 13052 undergraduate
students (including 6852 male and 6173 female) from the city of Zhengzhou in Henan province were recruited for the purpose of the study.
Mathematical statistics, literature review, questionnaire investigation, and logic analysis were adopted. In terms of body shape, BMI index
of both male and female undergraduates increased, and the T test of BMI index showed significant difference (P < 0.01). In terms of
physical fitness, the lung capacity (M=4028.81>3985.10, T =3.625, P<0.01) and the standing long jump (M=226.05>217.80,
T =22.054, P<0.01) were significantly decreased. The test scores of 50 meters, pull-up, standing long jump, 1000 meters
and sitting forward bending were improved to different degrees. Girls showed significant improvement in all indexes except 50m
(M=9.386>8.071, T =63.067, P=0.832>0.01). Only 7.51% of students pay much attention to their physical quality. The
importance of physical quality is directly proportional to the frequency of exercise. 67.72% of students exercise for less
than 30 minutes. The phenomenon of staying up late and being addicted to the Internet is very common. 1.64% of students
never stay up late and 45.63% stay up late for online entertainment. Students and departments pay insufficient attention to
physical health testing. Only 6.1% of the students read the test rules carefully before taking the test, and only 10.09% of the
students said their department would urge students to learn the rules. It is likely that the subjective factors such as attitude,
exercise habit, exercise frequency and daily work and rest jointly determine the physical fitness level of college students. The
intensity of physical education courses, the ratio of sports facilities, the attitude of each department to physical testing and the
rationality of physical health testing affect the development of students' physical health level. We suggest putting forward from the
aspects of innovating campus sports culture atmosphere, help students establish correct health cognition and exercise habits, enhance
the educational function of campus sports classes and facilities, and perfect the management system of physical health test in colleges
and universities.

Following Beijing’s winning bid to host the 2022 Winter Olympic Games, winter sports have ushered in a great development opportunity for adolescents in China. Beijing initiated the Ice and Snow Sports on Campus Program in 2016, however, one of the challenges is that the lack of quality snow sports instructors and access to ski resorts is limiting sustainable programs. Greek Peak Ski Resort, located in upstate NY, has a successful history of running snow sport educational programs that Beijing may be able to learn from. The purpose of this study was to assess and compare the Ice and Snow Sports on Campus Program in Beijing with the snow sports programs at Greek Peak Ski Resort, having a goal to explore sustainable education programs for adolescents. Literature research, program reports, field observation, and interviews with program directors and experts were used in this study to assess and compare the programs in Beijing and Greek Peak Ski Resort. The findings indicated that with the Ice and Snow Sports on Campus Program initiated in 2016 by the Beijing Municipal Education Commission, about 2.1 million K-12 students’ participation counts in ice and snow sports have been recorded. In 2021, more than 200 K-12 schools with ice and snow sports specialties were certified in Beijing. A total of 60 model courses with the topic in winter sports and Olympics have been developed to improve ice and snow sports teaching. The strong and historical school skiing program at Greek Peak Ski Resort includes about 55-57 K-12 school programs and 5 college PE programs each year, with an estimated student participation count of 20,000 per year. The collaboration between Greek Peak Ski Resort and local schools/colleges/universities offers sustainable educational programs, benefitting generations of students and all parties involved and efficiently sharing resources. The 2022 Beijing Winter Olympics provides a rare historical opportunity for multi-level and multi-dimensional cooperation between the sports and educational departments in Beijing. With supporting policies and guidance, the strategic goal of cultivating more young people to participate in winter sports is being achieved. Education programs provide opportunities for adolescents to learn winter sports skills and promote active healthy behavior. The collaboration between local schools, colleges/universities and Greek Peak Resort can be a good solution for Beijing to resolve the critical challenge of lack of quality instructors and easy access to winter sports facilities.
