El objetivo del estudio fue evaluar el valor nutricional de dietas de Panicum maximum suplementadas con 30% de follajes arbóreos mezclados con yuca (Manihot esculenta). Se compararon seis tratamientos: T0 (P. maximum), T1 (Leucaena leucocephala), T2 (Moringa oleifera), T3 (Tithonia diversifolia), T4 (Guazuma ulmifolia) y T5 (Hibiscus rosa-sinensis). Se determinó la composición química, fermentación y digestibilidad in vitro, así como la producción de ácidos grasos volátiles (AGV). Los datos se analizaron con un análisis de varianza. La proteína cruda fluctuó de 8.34% a 11.70%, y la fermentación y la digestibilidad de la materia seca aumentaron (hasta 38.23% y 18.23%, respectivamente) (p < 0.05) con T5, T2, T1 y T3. Además, T5 y T2 incrementaron (p < 0.001) el ácido propiónico, mientras que T1 y T3 incrementaron el ácido butírico. Se concluye que la adición de H. rosa-sinensis, M. oleífera, L. leucocephala y T. diversifolia mejoran el perfil de AGV, fermentación y digestibilidad de la dieta.

The maintenance of sodium/potassium (Na+/K+) homeostasis in plant cells is essential for salt tolerance. Plants export excess Na+ out of cells mainly through the Salt Overly Sensitive (SOS) pathway, activated by a calcium signal; however, it is unknown whether other signals regulate the SOS pathway and how K+ uptake is regulated under salt stress. Phosphatidic acid (PA) is emerging as a lipid signaling molecule that modulates cellular processes in development and the response to stimuli. Here, we show that PA binds to the residue Lys57 in SOS2, a core member of the SOS pathway, under salt stress, promoting the activity and plasma membrane localization of SOS2, which activates the Na+/H+ antiporter SOS1 to promote the Na+ efflux. In addition, we reveal that PA promotes the phosphorylation of SOS3‐like calcium‐binding protein 8 (SCaBP8) by SOS2 under salt stress, which attenuates the SCaBP8‐mediated inhibition of Arabidopsis K+ transporter 1 (AKT1), an inward‐rectifying K+ channel. These findings suggest that PA regulates the SOS pathway and AKT1 activity under salt stress, promoting Na+ efflux and K+ influx to maintain Na+/K+ homeostasis.
Performance of the supervised generative classifiers of spatio-temporal areal data using various spatial autocorrelation indexes
Authors: Karaliutė Marta , Dučinskas Kęstutis
Published: February 2023

This article is concerned with a generative approach to supervised classification of spatio-temporal data collected at fixed areal units and modeled by Gaussian Markov random field. We focused on the classifiers based on Bayes discriminant functions formed by the log-ratio of the class conditional likelihoods. As a novel modeling contribution, we propose to use decision threshold values induced by three popular spatial autocorrelation indexes, i.e., Moran’s I, Geary’s C and Getis–Ord G. The goal of this study is to extend the recent investigations in the context of geostatistical and hidden Markov Gaussian models to one in the context of areal Gaussian Markov models. The classifiers performance measures are chosen to be the average accuracy rate, which shows the percentage of correctly classified test data, balanced accuracy rate specified by the average of sensitivity and specificity and the geometric mean of sensitivity and specificity. The proposed methodology is illustrated using annual death rate data collected by the Institute of Hygiene of the Republic of Lithuania from the 60 unicipalities in the period from 2001 to 2019. Classification model selection procedure is illustrated on three data sets with class labels specified by the threshold to mortality index due to acute cardiovascular event, malignant neoplasms and diseases of the circulatory system. Presented critical comparison among proposed approach classifiers with various spatial autocorrelation indexes (decision threshold values) and classifier based hidden Markov model can aid in the selection of proper classification techniques for the spatio-temporal areal data.
Populism: Drivers, measurements and protectors
Authors: Burova Olga
Published: February 2023

Populism is a fairly young concept. It does not have a single definition, neither does it have a single ideology. Populists can operate in a wide spectrum — from the extreme left to the extreme right. They gain popularity by focusing on issues important to large groups of the population that are avoided by the political elite. In Europe it is immigration issue, in the USA it is the loss of jobs in industry; in Ukraine it is low income, unequal opportunities, unfair distribution of wealth, and corruption. Recently, there has been growing support for populist parties and politicians. Populists, in particular, support traditional social values, nationalism, and oppose immigration. Populists can influence politics, for example, the populist United Kingdom Independence Party initiated a referendum in June 2016 on the UK's membership in the European Union, which resulted in the victory of the supporters of Brexit - the exit of the UK. As Professor Inglehart notes, populism is spreading as a response to the transformation of values, populism expresses a "rollback" from post-materialist values. Populist politicians are unsuccessfully trying to find a solution to the new challenges that have arisen as a result of globalization and the formation of an artificial intelligence society. Thus, Donald Trump's proposals are predominantly xenophobic and authoritarian in nature. Another American politician, Bernard Sanders, notes the solution to the acute problem of economic inequality, but the reforms he proposes are ineffective. In this article, the author try to understand what this phenomenon is, what forms and drivers it has, and most importantly, how populism is measured in Europe and what examples of measurement there are in Ukraine. The results of a study in Ukraine presented in the article make it possible to identify trends of populism growth and find ways to oppose it.
Sociological dimensions of cyberbullying: essence, consequences, and coping strategies
Authors: Korzhov Hennadii , Yenin Maksym
Published: February 2023

The authors of the article based on a review of scientific sources, documents of international organizations, and legislation conducted a comparative analysis of different approaches to the definition of cyberbullying. According to the authors, cyberbullying is individual or group actions of aggression or violence against the individual, harassment using information technology, e-mail, messengers, chats, social networks, websites, mobile phones in order to humiliate, intimidate or cause moral harm. In contrast to traditional bullying, in cyberbullying the advantage of physical strength and higher social status becomes unimportant, while the uneven distribution of technological power increases, time and space constraints disappear, and the emotional threshold of social reactions reduces. Pupils and students are the first to be at risk of being victims of aggression on the Internet. Based on a review of foreign sources, strategies for minimizing and overcoming the negative consequences of cyberbullying at various levels — individual, organizational, institutional and systemic (legal and moral norms) — are considered. According to the authors, cyberbullying is a component of the broader concept of cyberviolence, which includes both proactive and reactive aggressiveness. Based on the data of the research “Prevention of violence against women in online resources during the elections in Ukraine”, it was found that the use of various forms of online violence against women in Ukraine is a common and destructive factor that has a very negative impact on their participation in political life. In this context cyberbullying is based upon historically determined socio-cultural stereotypes, as well as prejudices and myths about the social roles and opportunities of women to participate in civic and political life.
Практична філософія Григорія Сковороди і сучасність: до 300-річчя від дня народження

Published: February 2023

У доповіді зазначено, що філософія Григорія Сковороди є значущим явищем української культури, важливим чинником становлення та розвитку ідентичності українського народу і при цьому відповідає провідним світовим тенденціям сучасної практичної філософії. Сьогодні, на нинішньому етапі розвитку технологічної цивілізації, практична філософія діалогу Сковороди з приматом етичних цінностей набуває особливої актуальності, адже вкрай важливий аспект його спадщини полягає в тому, що він кидає виклик суспільству споживання, а шлях самопізнання, за Сковородою, означає розрізнення справжніх і позірних цінностей людського життя, відмову від усього зайвого і неважливого, гармонійні стосунки з іншими людьми і природою.

Added Morphological Characteristics of Muscle Scars, Maxillula and Mandible of Two Ostracod Genera Loxoconcha (Loxoconchidae) and Xestoleberis (Xestoleberididae)
Authors: Le D. D.
Published: February 2023

Total 23 species of the genus Loxoconcha and 21 species of the genus Xestoleberis were presented in this study. The results show that most species of the genus Loxoconcha consist of four adductor scars to arrange in a curved sub-vertical row and concave anteriorly, except L. pulchra carrying five, in which the top one is divided into two. The frontal scars with C-shape, opening anteriorly are presented in most of Loxoconcha species, however, the frontal scar with bean-shape or oval-shape is discovered in five species of L. japonica group. Most of L. kosugii bear the frontal scar with C-shape, but the frontal scar with Y-shape is found in several individuals. This phenemenon shows the close phylogeny between the genus Loxoconcha and Palmoconcha. About the genus Xestoleberis, chaetotaxy of setae on most appendages is a typical character of this genus, except for setae of exopodite on the maxillula. The published fossil records and the tendencies of change in the number of setae on the maxillula and mandible among three phylogenetic groups suggest that Group A or B is an ancestor of the genus Xestoleberis, and Group C is a derived group.
TEORI KELAS SOSIAL DAN MARXSME KARL MARX

Published: February 2023

Abstrak:           Karl Marx (1818-1883) memandang bahwa sejatinya aktor utama yang berperan penting dalam kelangsungan hidup suatu masyarakat adalah kelas-kelas sosial. Keterasingan yang dialami manusia pun sesungguhnya adalah hasil penindasan satu kelas oleh kelas lainnya. Untuk menghapuskan tindakan eksploitatif tersebut, Karl Marx mengemukakan perjuangan atau revolusi kelas. Karl Marx yakin bahwa kelas-kelas yang terbentuk pada suatu masyarakat dapat dihapuskan dengan revolusi tersebut sehingga keadilan pun dapat ditegakkan kembali. Dan pemikiran-pemikiran politik dan ekonomi Karl Marx tersebut juga dianggap sebagai ancaman terhadap kapitalisme Barat, khususnya pada periode sebelum Perang Dingin usai pada sekitar awal tahun 1980. Kata Kunci: Masyarakat, Kelas-Kelas Sosal, Kapitalsme.
THE SKILLS FOR MEASURING THE EFFECTIVE THERMAL DIFFUSION CONDUCTIVITY OF THE VAPOR CHAMBER WITH THE ÅNGSTRÖM THEORY
Authors: Lin Wei-Keng , Zhang Wen-Hua , Hsaio Kenny , Tseng Wen-Ching , Chu Yi-Jing
Published: February 2023

Most people measure the thermal resistance of vapor chambers by using Fourier's law of thermal conduction. However, Fourier's thermal conduction law is generally applied when the evaporator area is the same as that of the condenser, and this is completely different from the realistic condition; that is, the heated area of the evaporator is much smaller than the condenser area. Therefore, we proposed a new method to initially measure the thermal diffusivity of the test sample by the Ångström theory and then convert it into effective thermal diffusion conductivity of the vapor chamber. The Ångström theory is originally used for the one-dimensional test sample. However, the results of measurements that are applied to heat spreaders such as vapor chambers, heat pipes, or graphene are generally not accurate enough. The reason is that some test samples are not one-dimensional, or the test skill is not high. Therefore, the accuracy of measuring the effective thermal diffusivity of vapor chambers is very important for identifying the performance of the vapor chamber. The method in this paper using the Ångström theory has successfully divided the size of the current vapor chamber into three zones by the method of thickness-to-width aspect ratio. The repeatability error of obtained data is less than 5%, and the accuracy error is less than 10%.
Influence of periodic cyclic loading and rest period on soft clay consolidation
Authors: Atapattu Shashika , Indraratna Buddhima , Rujikiatkamjorn Cholachat
Published: February 2023

Railways are often subjected to periodic cyclic loading and intermittent rest periods. Excessive consolidation settlements can affect the performance of railway tracks built on the soft subgrade. The consolidation behaviour under railway loading conditions with rest periods has not been evaluated thoroughly. In this study, laboratory testing was conducted to investigate the influence of periodic cyclic loading and rest periods on the consolidation of Holocene soft clay from Ballina NSW. The specimens were subjected to a loading frequency of 1 Hz for 54 h with multiple rest periods. The recorded settlements and excess pore-water pressures (EPWP) during cyclic consolidation were employed to determine the corresponding hydraulic gradient, void ratio, resilient (dynamic) modulus and damping ratio. The settlement and accumulated EPWP can be observed during cyclic loading. In contrast, settlements do not occur within a rest period, despite the rapidly dissipating EPWP at the start of a given rest period. The maximum EPWP and settlements decrease as the number of resting period increases. An analytical model capturing the effect of cyclic loading and rest period is proposed where the unique relationships between the hydraulic gradient and the flow rate are established.

Published: February 2023

Introduction. Owing to limited clinical clerkships and travel restrictions related to COVID-19, recent medical student mentorship in orthopaedic surgery has been negatively impacted. The purpose of this Quality Improvement (QI) project was to determine if medical student awareness of orthopaedics as a possible career field may be improved through a mentoring program designed and delivered by orthopaedic residents.
Methods. A five-resident QI team developed four educational sessions aimed at a medical student audience. Forum topics included (1) orthopaedics as a career, (2) fracture conference, (3) splinting workshop, and (4) residency application process. Pre- and post-forum surveys were administered to student participants to assess changes in their perceptions regarding orthopaedic surgery. Data derived from the questionnaires were analyzed with nonparametric statistical tests.
Results. Of 18 forum participants, 14 were men and 4 were women. A total of 40 survey pairs were collected, averaging 10 per session. In the all-participant encounter analysis, there were statistically significant improvements in all outcome measures including interest in, exposure to, and knowledge of orthopaedics; exposure to our training program; and ability to interact with our residents. Those undecided regarding their specialty demonstrated larger increases in post-forum responses, suggesting that the learning experience was more impactful for that subgroup.
Conclusions. This QI initiative was a successful demonstration of orthopaedic resident mentorship of medical students, wherein perceptions of orthopaedics were favorably influenced by the educational experience. For some students with limited access to orthopaedic clerkships or formal one-on-one mentoring, forums like these may be an acceptable alternative.
Examining the views of trainers and trainees on the effectiveness of on-line Youtube guitar training
Authors: GAYRETLİ Şerif
Published: February 2023

YouTube, which enables individuals to access information by eliminating the concept of time and space, is becoming more and more involved in the education dimension every day. The purpose of this research is to examine the effects of guitar training videos published in Turkish on YouTube on guitar playing, in line with the views of trainers and trainees, and the effectiveness of YouTube on-line training in line with the views of educators and trainees. In this descriptive research, a scanning model was used. 30 trainers who regularly upload free training content to YouTube and 96 people who received training from these trainers participated in the research. As a data collection tool, the Opinions Questionnaire on Guitar Education on YouTube, which consists of five-grade likert type questions and open-ended questions, was used. As a result of the research; it is seen that most of the instructors broadcast to provide their information free of charge and to support the educational institution they are affiliated with, and the preferences of the students to follow these broadcasts are due to transportation, time and financial opportunities. In line with the statements of the participants, it was concluded that the students found the Turkish guitar training content published on YouTube useful, they were able to communicate with the trainers and the majority of them were able to learn guitar with this method.
“You Can Do Better Than That!”: Tweeting Scientists Addressing Politics on Climate Change and Covid-19
Authors: Biermann Kaija , Peters Nicola , Taddicken Monika
Published: February 2023

Climate change and the Covid-19 pandemic are global challenges in which scientists play a crucial role, and immediate political actions are necessary. However, in contrast to climate change, strong governmental actions have been taken during the pandemic. While climate change has been on the public agenda for several decades, the pandemic is a rather new issue. In such cases, social media offer scientists the potential to disseminate scientific results to the public and express calls to action and their personal views towards politics. Thus far, little is known about the extent to which scientists make use of this option. In this study, we investigated the similarities and differences between visible German climate experts and visible German Covid-19 experts regarding advocacy and assessments of policies and political actors on Twitter. We conducted a manual content analysis of tweets (N = 5,915) from 2021 of the most visible climate experts (N = 5) and the most visible Covid-19 experts (N = 5). The results show that climate experts addressed politics more often than Covid-19 experts in their tweets. The selected climate experts more often expressed negative evaluations, the degradation of competence and blaming. The Covid-19 experts, however, made more political calls for action. We assume that an issue’s history and context will affect scientists’ public assessments of politics. Our comparative study provides insight into the interrelations between science and politics in digital communication environments and elucidates visible scientists’ communication behaviours towards different socio-scientific issues.
La relación de los contextos de aprendizaje “abierto” versus “cerrado” con las abordajes de aprendizaje de los estudiantes rurales de primer ciclo
Authors: Duarte António Manuel , Figueira Ana Isa
Published: February 2023

RESUMENEl objetivo de este estudio fue investigar la relación entre las “abordajes de aprendizaje” (i.e., la combinación de la motivación y las estrategiasutilizadas en el aprendizaje) de los estudiantes rurales del primer ciclo de educación básica y el contexto del aula donde esto se lleva a cabo. Para la recogida de datos se llevaron a cabo entrevistas estructuradas con una muestra de los estudiantes sobre su abordaje de aprendizaje. También se caracterizaron sus ambientes de aprendizaje en el aula, a través de un cuestionario aplicado a sus propios maestros. Para una análisis general de la relación entre el contexto de aprendizaje con las abordajes de aprendizaje se llevó a cabo el teste Mann-Whitney para dos muestras independientes. En un análisis más discriminante, se calculó el coeficiente de correlación de Spearman entre los componentes particulares de esas dos variables. Los resultados apuntan a la existencia de una asociación entre una mayor exposición a un contexto de aprendizaje “abierto” (i.e., , centrado en los estudiantes) y el mayor uso por ellos de una abordaje de profundidad de aprendizaje (i.e., aprendizaje activa).Palabras Clave: abordajes de aprendizaje; contexto de aprendizaje; educación rural; territorio rural.ABSTRACTThe aim of this study was to investigate the relationship between elementary rural students’ “approaches to learning” (i.e., the combination of motivation and strategies used in learning) and their classrooms’ learning context. A sample of elementary students participated by answering to a structured interview on approach to learning while their teachers answered to a questionnaire on classrooms’ learning environment. For a general analysis of the relationship between learning context and approaches to learning a Mann-Whitney test for two independent samples was conducted. In a more discriminated analysis, it was also calculated the Spearman correlation between particular components of those two variables. Results point to the existence of an association between a higher exposure to an “open” learning context (i.e., student centred) and higher use of a “deep” approach to learning (i.e., active learning).Keywords: approaches to learning; learning context; rural education; rural territory.

Published: February 2023

With the increase of aging population, accompanied by a series of aging problems, the study showed that the probability of
chronic disease in the elderly population is 92.1%, and further research shows that the probability of having two or more
chronic diseases is 70.0%. Therefore, understanding of the distribution and spatial-temporal variation trend of risk factors
related to chronic diseases can provide scientific basis for the formulation of policies and intervention strategies for the
prevention and treatment of chronic diseases. It is of urgent practical significance to improve the quality of life of the
elderly and reduce the social medical burden. Analysis of the data indicated that after 1 year of continuous exercise
intervention, the experimental group’s blood pressure was controlled at a normal level in nearly 2 months [90 ~ 140mmHg/100
~ 160mmHg(SBP/DBP)]. The results showed that moderate physical activity can reduce stress and help control blood pressure
in patients with high blood pressure. After 1 year of targeted exercise intervention, the experimental group significantly
improved fasting blood glucose (controlled under 7.2mmol/liter) in nearly 2 months after the second questionnaire survey.
After the exercise, the blood glucose was controlled within the normal range and gradually increased. After one year of
exercise intervention, the blood lipid index of the experimental group was significantly different from that of the control
group, indicating that physical exercise has a positive effect on the elderly with hyperlipemia.

Published: February 2023

The COVID-19 pandemic has seriously increased anxiety prevalence among the public, including Chinese college students. However,
many exercises cannot be performed as usual under the stay-at-home order. The purpose of this study was to evaluate and compare
the effect of personalized individual aerobic-exercise and resistance-training prescriptions on anxiety in college students
during the COVID-19. This was a 12-week three-arm randomized control trial using the intention-to-treat principle. Sixty-six
college students with anxiety were recruited and randomized into aerobic-exercise (AE), resistance-training (RT), and
health-education group (HE). AE and RT groups also received health education. Measures on anxiety and physical activity
included Zung Self-Rating Anxiety Scale (SAS), Chinese College Students Mental Health Scale - Anxiety Subscale (CCSMHS-AS) and
International Physical Activity Questionnaire-Short Form (IPAQ-SF). All data were collected at the baseline, 4, 8, 12 weeks and
4-week post-intervention. All participants completed the intervention and measurements. The mean (SD) of SAS, CCSMHS-AS score
and physical activity was 56.36 (5.63), 19.27 (4.56), 1306.57 (1421.19) (met-min/week). After the intervention, 78.79% of
anxiety participants improved from anxiety to “normal”. Participants in all groups showed a statistically and clinically
significant improvement after 12-week intervention (p < 0.001). Moreover, such improvement was well-maintained in RT and HE
group as there were no significant differences in SAS and CCSMHS-AS at 4-week post-intervention compared to 12 weeks (p > 0.05).
However, the SAS score of participants in AE group showed a significant increase during the 4 weeks after intervention
(p < 0.05). No significant differences were observed in the effect of AE and RT on anxiety at each time-point (p > 0.05).
PA of participants in AE and RT group represented a significant improvement at 4-week post-intervention compared to baseline
(p < 0.01). Personalized individual aerobic-exercise and resistance-training combined with health-education resulted in a
similar effect on reducing anxiety and improving physical activity, and the effect was better than health education alone.
Furthermore, the effect of resistance-training and health-education on reducing anxiety was more stable than that of
aerobic-exercise. We recommended 45- to 60-minute home-based individual exercise (including 30- to 40-minute main exercise)
with progressive moderate-to-high intensity, 3 times/week for at least 12 weeks for those students with anxiety during the
COVID-19 pandemic.
The Effects of Yoga on College Students' Mental Health
Authors: Yumei Jiang , Yingya Pu , Bo Shen , Chen Ding
Published: February 2023

The mental health of college students is an increasingly serious public health problem. Effective and healthy interventions are
needed. More and more research has been conducted on yoga, but there are few randomized controlled trials (RTC) on effects of
yoga intervention on students' mental health. Therefore, this study examined effects of quality of yoga intervention on mental
health in college students. We used PubMed (Medline), Cochrane, Web of Science, CNKI, VIP Chinese Science and Technology Journal
Database (VIP) and WanFang Database to search randomized controlled trials (RCTs) of yoga intervention in college students' mental
health. After the screening, 17 articles met the requirements and were included along with the utilization of the Cochrane bias
risk assessment tool Rob2.0 to evaluate the quality of the included articles. Of 17 articles reviewed, three articles were rated
as "low risk of bias", five articles were rated as "possibly at risk of bias", and nine articles were rated as "high risk of bias".
The 17 studies predominantly consist of low methodological quality and lack multi-centered, large-sample collaborative research.
Almost all researchers mentioned the use of "randomization" in their articles, but they did not indicate which randomization
method was used. There was no description of allocation concealment, blinding, case shedding, case follow-up etc., and it was
impossible to judge whether the trial design was correct, or whether random grouping was, indeed, undertaken. This study found
that most of the so-called "randomized controlled trials" are doubtful, which virtually reduces the strength and credibility
of this study. Therefore, improving the research quality of yoga intervention and standardizing the writing of scientific
research articles are the problems need to be solved in the current field of sports psychology research in China. Current
evidence shows that yoga exercise can relax the body and mind, thereby improving the level of mental health, and complete
yoga (exercise, breathing, meditation) significantly relieves the symptoms of depression. Performing yoga postures and exercises
promotes blood circulation, effectively improves sleep, and regulates breathing to stabilize autonomic nerves, relieve stress,
and eliminate mental tension. In the future, yoga practice can be used as a non-medical intervention to treat mental illness.
The quality of the current randomized controlled trials of yoga intervention in the mental health of college students is
generally low. Randomized controlled trials with reasonable methodological design, strict implementation, and sufficient
follow-up time are still needed. It is recommended that researchers should strengthen the systematic study of clinical trial
methodology and strictly refer to the Cochrane manual list for clinical research reports in order to improve the quality of
literature reports.
The Development of College Ice Hockey in China
Authors: Li Hongxin , Bai Yunchao
Published: February 2023

After winning the right to host the 2022 Winter Olympics, ice hockey has become more popular in colleges in China.
However, the challenges to college hockey’s development in China are not surprising as new markets tend to experience
struggles due to the fluidity of logics (Thornton & Ocasio, 2008) and issues of establishing legitimacy (Deephouse & Suchman,
2008). Considering this, those hoping to establish new sport institutions within untapped contexts are burdened with the arduous
task of simultaneously creating and maintaining institutional structures while working to establish legitimacy (Washington, 2004).
In this study, we draw from the concept of institutional work to understand how Chinese collegiate administrations and other relevant
stakeholders have created, built, and sustained the emergent ice hockey environment for universities in China. This inquiry was guided
by the following research questions: what factors at various institutional levels influenced the development of college ice hockey in
China? How did institutional leaders utilize Beijing 2022 Winter Olympics to leverage the development of college ice hockey? To answer
these questions, we employed qualitative case study methodology. Primary data were collected through 18 semi-structured interviews with
university faculty, student athletes, and administrative officials. Secondary data were collected via archived documents from numerous
sources. Data analysis was consistent with the Gioia methodology, wherein we identified first-order concepts, second-order themes, and
aggregate theoretical dimensions (Gioia, Corley, & Hamilton, 2012). Preliminary findings suggest the development of college ice hockey
in China has framed the development model with opportunities and multiple resources. Organizing capability, the hockey infrastructure,
and legitimating issues impacted the development of college ice hockey. The 2022 Winter Olympics is a good opportunity for developing
college ice hockey and it is bringing in additional funding and support to college hockey teams and athletes. The development of college
ice hockey in China always combines with nationalism, and some student athletes also represent the national team for China. In addition,
youth ice hockey development in Beijing and Heilongjiang is providing ice hockey talents for the college hockey teams around China.
College ice hockey in China was facing challenges in an environment from different institutional logic orders. This study provides
insights into the relationship among the nationalism, Olympics, and the development of winter sport in college. Additionally, this
research outlined how public and private actors may work to create new governance structures that may be seen as legitimate.
The Restrictive Factors and Practical Path of Sports-Medical Integration Under the Background of COVID-19 Pandemic
Authors: Chen Yonghuan , Jiang Yanan , Yan Xiangning
Published: February 2023

This paper explored the restrictive factors of realizing the integration of sports and medicine in China under the background of “COVID-19 pandemic” and analyzed the path of realizing the integration of sports and medicine by combining it with “Healthy China” strategy and “National Fitness Program”. We used document and expert interview method. In the new era, people’s desire for a better life has become the most extensive demand, and the sudden outbreak of epidemic makes people’s demand for health become the first demand. The importance of people’s health raises “Healthy China” as the national development strategy, which has become the opportunities to realize the “integration of sports and medicine”. At present, China has formed three “sports-medical integration” models: the combination of the government and the market, the fitness guidance center of the hospital and the physique monitoring center of the community. Among them, the model of community physique monitoring center is in line with China's national conditions, but the development of this model still needs policy and financial support. At present, China’s “integration of sports and medicine” is still facing a few challenges: a) The conceptual understanding remains weak while the belief to medical treatment and negligence of sports is strong; b) There is lack of standards of sports knowledge and skills, so it is difficult to reach a consensus; c) The sports and medicine industry has a low level of integration and lacks an integrated environment. The impact of the COVID-19 pandemic is not only a challenge but also an opportunity to realize the integration of sports and medicine. At present, with the support of national strategy, “integration of sports and medicine” is in the best historical development opportunity. At the same time, however, it also faces a series of contradictions. In this regard, it is necessary to deepen the essence of the two to carry out conceptual innovation and enhance the national recognition of the functional value of “sports-medicine integration”. Strategies include cooperating with sports medicine institutions to build a service platform, strengthening the integration of sports and medicine disciplines while building a qualification certification system and cultivating comprehensive talents, and improving the environment of “integration of sports and medicine” with building the foundation of harmonious symbiosis.

Published: February 2023

INTRODUCCIÓN: Los resultados con respecto al uso del zinc en los niños hospitalizados por neumonía siguen siendo contradictorios.OBJETIVO: Demostrar la eficacia del zinc como adyuvante.MATERIAL Y MÉTODO: Ensayo clínico aleatorizado doble ciego en menores de 5 años. Se administró sulfato de zinc o placebo por vía bucal. Los niños recibieron 10mg/día o 20mg/día de zinc según su edad, administrados durante 14 días. Se registraron variables clínicas y de laboratorio, al ingreso, a las 72 horas y a los 7 días. La muestra consistió en 100 pacientes por grupo. La variable primaria fue el tiempo necesario para la resolución de la neumonía y las secundarias, el tiempo para la resolución de los indicadores clínicos, falla terapéutica y los efectos adversos. Las variables fueron contrastadas mediante la prueba t de Student o prueba de Mann-Whitney y la prueba χ2. La significancia estadística fue considerada con valor de p <0,05.RESULTADOS: En el grupo que recibió zinc se registró menor tiempo de resolución de la neumonía 72 vs 120 horas (p<0,001), así como de las horas necesarias para normalizar cada indicador clínico de neumonía (p<;0,001). Igualmente la estadía hospitalaria fue mucho menor [(mediana 5(4,8-5,2) vs 9(8,3-9,7) (p<0,001)] como también el riesgo de falla terapéutica, el riesgo relativo fue 0,17 IC 95(0,07-0,38) p<0,0001. No hubo diferencias significativas en la aparición de efectos adversos [riesgo relativo 1,67 IC 95 (0,77-3,63)].CONCLUSIÓN: La adición de zinc a la terapia general en los niños con neumonía demostró ser eficaz sin eventos adversos relevantes.

It is in this regard, that this study investigated the attitude, and productivity of cataloguers in tertiary institutions in Edo State. Descriptive survey research design was adopted for this study. The population comprised of 81 cataloguers in Edo State. The study made use of total enumeration sampling technique. Reliability co-efficient of the constructs of this study are as follows: Productivity - 0.71, and Technical skills- 0.71. A validated questionnaire was used to collect data. Data was analysed using descriptive and inferential statistics. Findings of the study revealed that there was significant influence of attitude on the productivity of cataloguers (Adj. R2=0.100; p<0.002) in tertiary institutions in Edo State. The study concluded that attitude and technical skills have positive influence on productivity of cataloguers in Edo State. Therefore, the study recommended that institutions should strive to motivate cataloguers and provide current cataloguing and classification tools so as to ensure they have positive attitude to cataloguing.

Objetivo: identificar el impacto de la medida de confinamiento social, decretada por el gobierno colombiano ante el covid-19, sobre los niveles de ansiedad y los comporta­mientos alimentarios de los deportistas adscritos a selecciones Antioquia. Metodología: estudio observacional descriptivo de corte transversal en deportistas de altos logros deportivos de Indeportes Antioquia que fueron atendidos en el área de medicina, entre enero y agosto 2020. Se indagó sobre aspectos de ansiedad y compor­tamientos alimentarios, ocasionados durante la medida de aislamiento social derivada de la pandemia por covid-19. Resultados: la encuesta fue respondida por 150 deportistas. En hombres, la ansiedad aumenta a medida que se incrementa el grupo de edad. En las mujeres, el fenómeno es opuesto. Para la misma calificación de ansiedad alta, el porcentaje va disminuyendo con la edad. Con referencia a los comportamientos relacionados con la alimentación, analizados bajo una circunstancia tan compleja, como es la pandemia por covid-19, permitió a los profesionales del deporte y la salud direccionar recomendaciones efectivas para los deportistas que asesoran, frente al manejo de la ansiedad y el control de ciertos comportamientos negativos que pueden afectar la salud y el rendimiento deportivo. Conclusiones: los resultados con respecto a la ansiedad coinciden con estudios actua­les, en los que, en términos generales, las poblaciones evaluadas muestran niveles de ansiedad baja y esto se relaciona con una escasa tendencia a alteraciones en la conducta alimentaria en la población estudiada.

Published: February 2023

Los alimentos de origen animal como la carne de pollo, res, pescado y cerdo poseen una amplia demanda en todo el mundo debido, entre otros aspectos, a su valor nutricional, asociado al alto contenido proteico. No obstante, este tipo de proteínas son susceptibles de sufrir reacciones de oxidación, las cuales pueden mediar procesos de fragmentación, agregación, pérdida de solubilidad, funcionalidad y digestibilidad proteica; eventos implicados en la pérdida de su valor nutricional. En este sentido, las proteínas agrega­das tienden a no ser digeridas en el tracto gastrointestinal y acumularse en el intestino (colon), donde la microbiota colónica las degrada a productos mutagénicos como fenol y p-cresol, lo que incrementa el riesgo de cáncer colorrectal. Por otra parte, los ami­noácidos o péptidos oxidados liberados en la digestión podrían incorporarse en las vías de señalización celular intestinal y favorecer o exacerbar procesos intestinales crónicos como colon irritable o enfermedad de Crohn. Debido al gran interés de esta temática en los últimos años, el objetivo de esta revisión es realizar una descripción general del impacto de proteínas oxidadas de origen animal sobre la salud intestinal.

Published: February 2023

La pancreatitis en pediatría se consideraba anteriormente una enfermedad poco fre­cuente; en la actualidad se reportan 13.2 casos por 100 000 niños/año. La causa más importante de pancreatitis en la población pediátrica, después de la etiología biliar, son los medicamentos (13% de los casos). Uno de los principales medicamentos como causa de pancreatitis en pediatría es el ácido valproico (AV); el cual puede inducir una pancreatitis aguda. Aquí se presentará el primer caso de pancreatitis por AV en población pediátrica reportado en Colombia. Se trata de un paciente de cuatro años, con trastorno en el neurodesarrollo por un síndrome de TORCH, quien tomaba AV a largo plazo por un trastorno de la conducta. Ingresó a una institución de alta complejidad donde se diagnostica pancreatitis aguda con signos de necrosis en tejido pancreático secundario a uso de AV. Se suspendió el medicamento con resolución de su cuadro clínico y alta médica hacia el día 15
Quantitative wear indicators in carbide tools with variation in hardness
Authors: Grubyi S.V.
Published: February 2023

The paper considers the method of calculating the rate of deterioration, wear and durability in the carbide tools on the example of prefabricated cutters with the replaceable polyhedral inserts, including those with the wear-resistant coatings. Equations are proposed that relate wear rate of the tool back surface with the cutting speed and the tool material hardness, as the cutting temperature function. It is shown that practical implementation of the calculation method is appropriate for stable conditions with coefficients in variation of the processed and tool material hardness within the 0.1 limit.
