Effect of diets with glycemic load arrangement on blood glucose levels in young soccer athletes Background: Carbohydrate arrangement considering the glycemic index (GI) and glycemic load (BG) are important to support the performance of athletes.Objective: To examine the effect of diets with glycemic load arrangement on blood glucose levels in young soccer athletes.Methods: Quasi-experimental study on 14 male young soccer players aged 15-18 years old at Terang Bangsa Soccer School. Each subject completed 4 trials separated by at least 7 days as a washout period. Diets provided consist of high GI with high GL diet (H-H), low GI with high GL diet (L-H), high GI with low GL (H-L), and low GI with low GL diet (L-L). Collected data were fasting blood glucose level (BGL 0), blood glucose level one hour after intervention (BGL 1), blood glucose level two hours after intervention (BGL 2), and blood glucose level after exercise (BGL 3).Results: The results of paired t-test analysis showed that there were differences between fasting blood glucose level and blood glucose level one hour after intervention, blood glucose level one hour after intervention and blood glucose level two hours after intervention, blood glucose level two hours after intervention and blood glucose level after exercise in the H-H and L-H diet group. In the L-L diet group, there were differences between BGL 2 and BGL 3. One-Way ANOVA analysis showed that there were no significant differences in blood glucose levels one hour after the intervention, blood glucose level two hours after intervention, and blood glucose level after exercise between groups.Conclusions: High glycemic load diets influence the increase in blood glucose levels at 1 hour postprandial and after exercise. Low glycemic load diets influence the increase in blood glucose levels after exercise. Diets with the arrangement of glycemic index and glycemic load did not affect blood glucose levels between diet groups.

Effect of jelly containing of porang (Amorphophalus oncophyllus) glucomannan and inulin as a snack to the body weight, BMI, body fat, total cholesterol, and triglyceride levels in obese adultBackground: Obesity is a major risk factor for noncommunicable diseases, especially cardiovascular disease. Porang glucomannan and inulin are water-soluble fibers that have been widely studied for their health benefits. Jelly products that contain both types of fiber are expected to have the ability to support the diet program in adults with obese nutritional status. Objective: To determine the effect of giving jelly containing a combination of glucomannan porang and inulin on body weight, BMI, body fat, total cholesterol, and triglyceride levels in obese adults.Methods: This research is a randomized controlled trial using a pre and post-test design. A total of 55 subjects who live in the Special Region of Yogyakarta, participated in the study until the end of 8 weeks. Subjects were divided into 3 groups; 18 people in the group who were given jelly containing glucomannan porang and inulin (porang-inulin jelly group), 17 people in the group who were given placebo jelly (placebo jelly group), and 20 people in the negative control group who did not get jelly (negative control group). All subjects received a low-calorie diet intervention of 1,500 kcal in the first month and 1,200 kcal in the second month. Results: There was a significant reduction in body weight and BMI (p<0.05) in all groups, but there was no difference in the effect between the porang–inulin jelly group and the other groups (p>0.05). Clinically, there was a significant decrease in body fat percentage in the porang-inulin jelly group, in subjects with the category of an excess fat percent (-0.90 ± 0.49%) and obesity (-1.48 ± 0.83%). A significant decrease in fat percentage also occurred in the porang-inulin jelly group, both in male subjects (-1.42 ± 0.50%) and female (-1.15 ± 0.82%), while in the placebo jelly group and negative control, the decrease did not occur in all categories and genders. There was an increase in total cholesterol levels in the negative control group (p<0.05) after the study (+7.45 ± 13.18 mg/dL). In the porang-inulin jelly group, the increase in cholesterol levels did not occur significantly either in general or based on clinical categories and gender. Conclusion: Consumption of porang-inulin jelly may support weight loss programs, BMI, percent body fat, and inhibit the increase of total cholesterol and triglyceride levels in adults with obese nutritional status.

Health status and micronutrient intake among vegetarian and non-vegetarian in BaliBackground: Several studies have reported that vegetarian diets have health benefits for those adopting the diets.Objective: This study aimed to compare anemia status and micronutrient intake between vegetarians and non-vegetarians in Bali.Methods: This cross-sectional study was conducted in Bali. A total of 240 samples consisting of 160 vegetarians and 80 non-vegetarians were randomly selected. Hemoglobin (Hb) and fasting blood sugar levels were measured using the cyanmethemoglobin method and enzymatic colorimetric, respectively. Meanwhile, the data on micronutrient intakes were collected by interviews using the semi-quantitative food frequency questionnaire (SQFFQ). The data were analyzed using descriptive statistics, and the Mann-Whitney test was performed to analyze the differences.Results: The study’s results showed that the mean Hb levels in the vegetarian group were significantly lower than non-vegetarians (p=0.002; p<0.05), and the anemia status in vegetarian women were higher (22.5%) than non-vegetarian women (2.5%). The mean fasting blood glucose level in non-vegetarians was significantly higher than in the vegetarian group (p=0.000; p<0.05). There were no differences in zinc (Zn) intake between vegetarians and non-vegetarians, but there were significant differences (p<0.05) in vitamin C, vitamin D, vitamin B12, folic acid, magnesium (Mg), calcium (Ca), and iron (Fe) intakes.Conclusions: There were differences in anemia status and fasting blood glucose levels between vegetarians and non-vegetarians. The fasting blood glucose levels of non-vegetarians were higher than vegetarians, and there were differences in the intake of certain micronutrients between vegetarians and non-vegetarians.

Published: December 2021

The effect of the multi-exercise program on cognitive function in overweight and non-overweight elderlyBackground: Cognitive function is the factor that determines the disability of the elderly to live a healthy and independent life. The results of studies regarding the protective effect or detrimental effects of overweight or obesity on cognitive function in the elderly are still controversial. Objective: This study aims to determine the effect of the multi-exercise program on cognitive function in the elderly based on nutritional status.Methods: This quasi-experimental study with a pretest-postest design study involved 37 elderly aged 60-74 years. Body mass index (BMI) derived from the measurement of body weight and height were grouped into overweight and not-overweight. Both groups received a multi-exercise in the form of gymnastic exercise (30 minutes), square stepping exercise (30 minutes), and puzzle games (30 minutes). The intervention was given 12 times with a frequency of 3 times per week. Cognitive function was measured by using the Mini-Mental State Examination (MMSE) questionnaire. Data analysis used paired sample t-test and independent t-test. Results: The multi-exercise program intervention given affected improving cognitive function in the overweight elderly group (p=0.003). However, it is different from the non-overweight elderly group who did not show a significant effect of the multi-exercise program on the cognitive function (p=0.184) even though there was an increase in the mean cognitive function at the end of the intervention. Conclusions: Multi-exercise program intervention for 4 weeks with a frequency of three times per week can improve the cognitive function of the elderly, but statistically only significant in the overweight elderly group.
Technology Parks and Innovation Areas of Developing Countries as a New Way for Retuning Talents (Case Study: Pardis Technology Park)
Authors: Mamhoori Ali
Published: December 2021

“Talent acquisition, transformation and management are ?critical anchors for the growth of the industry”—Nandan Neilkeni As a result of rapid pace of science and technology around the world and the monstrous intrusion of social media into people’s lives, the changes are no longer related to a generation, decade or a period, but everything can change in a moment. Therefore, sticking to the methods of the past years or decades is a disaster. Today, the number of specialists among the manpower is higher than before, and the ideologists are like the countries’ soldiers fighting on the economic and entrepreneurial front. Science and technology are provided by talents, and they have created interactions regarding socio-economic progress in developing countries.Tec parks are safe havens for returning talents in developing Countries. With certain infrastructures and policies, parks have an essential role in returning talents.This paper is an attempt to explore science and technology for that purpose content analysis technique is used. Furthermore, it discusses the role of Pardis Technology Park in promoting the science and technology.
The T-shaped “axe” from Northeast Honduras: Observations on chronology and function of a pre Columbian stone tool
Authors: Healy Paul F. , Savage Daniel
Published: December 2021

This paper provides a description and analysis of a distinctive type of pre-Columbian stone tool, usually termed a T-shaped axe, found almost exclusively in Northeast Honduras, Central America. There have been very few detailed or technical studies of lithics from Honduras. Early archaeological research and the current understanding of the regional prehistory are included, with Northeast Honduras viewed as a frontier zone located between the Mesoamerican and Isthmo-Columbian culture areas. Our study examines, in particular, a collection of these tools curated today at the Cambridge University Museum of Archaeology and Anthropology (CUMAA). The 39 (whole and fragmentary) specimens were collected between 1937 and 1939, from the Bay Islands, Northeast Honduras, but have never been published. This paper classifies the collection specimens into five varieties, based on morphology, with sample statistics, form dimensions, and illustrations provided for each. Manufacturing technology is primarily percussion flaking. The tool type is compared with similar specimens excavated and described from the Bay Islands and adjacent Honduran mainland, and with similar appearing implements from elsewhere in Central America. Insights about the possible age and function of these unusual, and distinctive, lithics are included. Based on preliminary macroscopic and microscopic analyses, it is concluded that the tools may have been employed as agricultural implements (hoes or spades), primarily for digging activities, rather than as axes or weapons used for cutting and slicing. It is most likely that these implements first appeared about 800 CE, and continued in use until at least 1400 CE. The tool type is most probably a local (not imported) product. More functional analysis is encouraged.
Ética, argumentación e igualdad: una propuesta de fundamentación filosófica del principio de igualdad desde la teoría ética del discurso
Authors: Prono Santiago
Published: December 2021

Trabajos recientes demuestran un interés renovado en el análisis de la igualdad como principio fundador del Estado democrático de derecho. Se trata de estudios que evidencian un esfuerzo conceptual por abordar el problema desde el punto de vista de la aplicación y el reconocimiento efectivo del principio de igualdad, pero que dan por supuesta o dejan de lado su fundamentación. Ante estos planteamientos, este trabajo explora una propuesta de justificación filosófica del principio de igualdad en el marco teórico de la ética del discurso de Karl-Otto Apel. La idea es tomar en cuenta el método reconstructivo de esta teoría para identificar un principio de igualdad siempre presupuesto en los discursos prácticos y conferirle así una fundamentación última.
Objetores de Descartes, ¿y también de Frege? Apuntes críticos al artículo “La naturaleza de las entidades matemáticas. Gassendi y Mersenne: objetores de Descartes”
Authors: Méndez Pinto Emilio
Published: December 2021

En esta discusión expongo algunas objeciones a las siguientes tesis de Velázquez 2020: 1) que tanto Descartes como Frege sostienen que las entidades aritméticas son irreductibles a procesos empíricos; 2) que, en el caso de Descartes, dichas entidades son “perennes, inherentes a la propia constitución y funcionamiento de la mente” y 3) que Frege impugnó la filosofía matemática (aritmética) de Mill por psicologista. Sostengo que la segunda tesis no es, per se, controversial, pero que sí lo es en el contexto del artículo de Velázquez.

Abstract: In the present scenario, it is quite aware that almost every field is moving into machine based automation right from fundamentals to master level systems. Among them, Machine Learning (ML) is one of the important tool which is most similar to Artificial Intelligence (AI) by allowing some well known data or past experience in order to improve automatically or estimate the behavior or status of the given data through various algorithms. Modeling a system or data through Machine Learning is important and advantageous as it helps in the development of later and newer versions. Today most of the information technology giants such as Facebook, Uber, Google maps made Machine learning as a critical part of their ongoing operations for the better view of users. In this paper, various available algorithms in ML is given briefly and out of all the existing different algorithms, Linear Regression algorithm is used to predict a new set of values by taking older data as reference. However, a detailed predicted model is discussed clearly by building a code with the help of Machine Learning and Deep Learning tool in MATLAB/ SIMULINK.

Introducción: El engagement y el optimismo aportan a la salud mental, por tanto, es importante avanzar en la investigación de estos fenómenos psicológicos poco estudiados en Colombia. Objetivo: Analizar la relación entre el engagement y el optimismo en un grupo de trabajadores colombianos, e identificar el papel predictivo de la edad y la antigüedad en la organización en el engagement y el optimismo. Materiales y métodos: Se utilizó una estrategia asociativa donde participaron 298 trabajadores (M=124-H=174) de una organización del sector telecomunicaciones. Se aplicó un cuestionario sociodemográfico, el Utrecht Work Engagement Scale-17 y el Life Orientation Test. Las hipótesis se probaron mediante correlación de Pearson, análisis de varianza y modelo de regresión lineal múltiple de pasos sucesivos. Resultados: Las dimensiones del engagement se correlacionaron con el optimismo vigor (r=0,42, p<0,01), dedicación (r=0,26, p<0,01) y absorción (r=0,20, p<0,01)). Conjuntamente, se encontraron diferencias en la dedicación en función de la edad (p=0,01) y la antigüedad (p=0,04). Los modelos predictivos reportaron asociaciones entre edad y vigor (β=0,25, t=4,2, p<0,000), dedicación (β=0,202, t=3,38, p<0,001) y absorción (β=0,145, t=2,4, p<0,017). Conclusiones: Existe una relación positiva entre engagement y optimismo. En este estudio la edad es un predictor del engagement, pero no del optimismo.

Published: December 2021

O objetivo deste trabalho foi contextualizar a agricultura familiar e a sua vinculação ao Programa Nacional de Alimentação Escolar no estado de Santa Catarina no período de 2012 a 2017. Para isso, foi desenvolvido um estudo do tipo analítico de base documental, desenvolvido em uma perspectiva longitudinal retrospectiva. Foi utilizado como fonte de dados os editais de chamadas públicas para aquisição de alimentos da agricultura familiar para a alimentação escolar e, de forma complementar, a partir do Censo Escolar, os relatórios relativos ao número de alunos matriculados na rede de ensino públicas dos municípios que publicaram editais, indicadores socioeconômicos e demográficos dos municípios de Santa Catarina e do Censo Agropecuário Brasileiro. Foram analisados 821 editais de chamada pública, publicadas por 231 municípios catarinenses, que predominantemente são classificados como de pequeno porte. Quando o porte foi associado com indicadores de qualidade da aquisição, como o per capita de alimento saudável representado por frutas, hortaliças e leguminosas constatou-se que os municípios de pequeno porte compraram 46,57% mais alimentos saudáveis do que os de grande porte no último triênio. Sobre o percentual de aquisição de alimentos da agricultura familiar, observou-se que, a partir de 2014, ocorreu um aumento significativo na média de aquisição. Conhecendo as características do estado e sua potencialidade de produção de alimentos, ainda é preciso avançar, quantitativamente, na participação deste modelo de aquisição de alimentos para a alimentação escolar.

Published: December 2021

Relevance . Maintaining the health of migrants while adapting to the new climatic and geographical conditions of residence is an urgent task. The impact of non-specific factors on the body of migrants in new climatogeographic conditions leads to the strain of regulatory and adaptive mechanisms, and in extreme cases to their failure. Objective - to determine the features of heart rate variability in young Tajiks, depending on the type of temperament living in Krasnoyarsk for more than a year. Materials and Methods: A study of heart rate variability in 63 Tajiks aged 18-40 years with different types of temperament, living in Krasnoyarsk for more than a year, was conducted. The types of temperament were determined by indices in accordance with the method of identifying VP-types of temperament according to E.Yu. Petrosyan, Yu. I. Savchenkov. The following indicators of heart rate variability (HRV) were evaluated: heart rate, the power of the high-frequency, low-frequency and very low-frequency spectrum (BV, MV-2, MV-1) of the HRV component, the voltage index of regulatory systems (IN), the centralization index (CI) and the activity index of regulatory systems. To assess the statistical significance of the differences between the samples, the Students criteria were used. Results and Discussion. It was revealed that migrants with an intense type of temperament after moving to a new place of residence increased the indicators of heart rate, BV and IN. At the same time, in the studied groups with a calm and adequate type of temperament, the power of BV was significantly reduced, with an increase in heart rate and CI. The conclusion is made about the influence of typological features of temperament on HRV indicators, when adapting to new climatogeographic living conditions. Individuals with an adequate type of temperament demonstrate the normal functioning of the adaptive capabilities of the body. In individuals with the calm type, an increase in the tension of the regulatory mechanisms was revealed. Conclusion . Significant changes in HRV are demonstrated by migrants with an intense type of temperament, in particular, they are characterized by a high voltage of regulatory mechanisms.

Relevance. The study of the microbiological composition of periodontal pockets in inflammatory diseases of periodontal tissues is of great importance directly for the effective treatment and understanding of the pathogenetic stages of these diseases. Objective: to study the microbiological landscape of periodontal pockets with inflammatory diseases of periodontal tissues. Materials and Methods. 62 patients aged 20 to 45 years were selected and divided into groups depending on the form of periodontitis: with localized aggressive periodontitis - group №1, group №2 - with chronic generalized periodontitis, group № 3 - with exacerbation of chronic generalized periodontitis. The material for the study was taken from the periodontal pockets and examined by cultural and microbiological methods. Results and Discussion. It was found that the proportion and number of microbial associations in the periodontal pockets of different depths differs. In localized aggressive periodontitis, mainly facultative Gr+ (A. actinomycetemcomitans) and Gr- (St. aureus, Str. mitis) anaerobes were found in the periodontal pockets no more than 4 mm. In generalized chronic periodontitis of moderate degree, the same microorganisms were present in the periodontal pockets as in the localized form, but Str. mitis was more common among facultative aerobes. With the exacerbation of generalized chronic periodontitis from facultative anaerobes, St. aureus was more common and the proportion and number of A. actinomycetemcomitans significantly increased. Conclusion. According to the results of the study, the microorganisms that inhabit the periodontal pockets in inflammatory diseases of periodontal tissues mainly belong to facultative Gr+ and Gr - anaerobes, obligate Gr+ and Gr-anaerobes and yeast fungi.

«Hay algo de común a las tecnologías de poder y a la ley, que es precisamente la técnica hipomnésica que constituye la base de las psicotécnicas que forman la épiméleia. Ahora bien, estas psicotécnicas de sí son esas a las que la escuela introduce desde la antigüedad, pasando por la iglesia hasta la escuela laica, para un sí mismo que, en la modernidad, se vuelve así un nosotros; el nosotros de la mayoridad (liberado del dogma religioso) que piensan Kant y Condorcet. No preguntarse por la duplicidad esencial del pharmakon que aquí aparece es cerrarse a la posibilidad de pensar los otros tipos de pharmaka que constituyen las psicotecnologías movilizadas por el cine y por la televisión, y sus efectos sobre la individuación psíquica y colectiva, es decir, sobre sí mismo.»
Reensamblar la ciudad o cómo los estudios sociales y turísticos pueden influir la narrativa geo-socio-antropológica
Authors: Nava La Corte Fernando
Published: December 2021

El presente trabajo busca exponer algunas maneras de apropiación espacial en la zona turística de la comuna trece en Medellín, Colombia. Esta exploración se hace teniendo en cuenta el uso que las personas tienen del lugar en relación con su organización espacial, la disposición del mobiliario en el espacio y su inserción urbana. Así mismo, la aproximación metodológica que se plantea es de carácter cualitativo y el trabajo de campo empírico está circunscrito al universo narrativo con el que se busca explicar qué hace familiar un lugar y para quién es familiar ese lugar, lo que lleva a revelar los grados de integración y disuasión que existen en el espacio.

En esta vía, el objetivo del presente documento se enfoca en identificar cuáles han sido los impactos socioculturales en el área de amortiguación ocasionados por la actividad turística. Para ello, se analiza la teoría del habitar, la información clave a partir de los recorridos turísticos que se ofrecen, la observación participante y las entrevistas a diferentes actores del lugar que permitieron hacer una recopilación de datos y los testimonios que abonaron a la revisión crítica. Las conclusiones muestran que no hay solo un antes y un después, o una sola imagen capaz de abarcar toda la comuna, lo que sí existe son modos de ver y narrar la comuna trece. De igual manera inferimos que las políticas turísticas y territoriales regionales propician un desarrollo para las comunidades nativas, pero, siguen existiendo niveles de desigualdad social y polarización socioespacial. No todo está perdido en la comuna trece en Medellín Colombia; pues el grafiti de varios artistas nacionales e internacionales testifica y conmemora lo vivido en el barrio como punto medular de una transformación socioespacial permanente.

The interaction relationships among agricultural certification labels or brands: evidence from Chinese consumer preference for fresh produce
Authors: Wang Yiqin , Wang Jingbin , Han Dan , Lv Shanshan , Chen Mo , Yin Shijiu
Published: December 2021

China uses a multilevel agricultural certification system; however, its implications are not well understood. In this study, we used tomatoes as an example in a series of Becker-DeGroot-Marschak auction experiments to determine consumers’ willingness to pay (WTP) toward three safety certification labels and two kinds of brands. Then, based on the auction experiment results, we designed a menu-based choice experiment to assess the interaction relationships between the safety certification labels and brands. The results showed that consumers were generally willing to pay a premium for tomatoes with safety-certified labels (especially for organic labels) and brands (especially for the enterprise brand). Providing consumers with additional information regarding the certification remarkably improved their WTP for tomatoes with organic and green labels. The menu-based choice experiment suggested that the organic and green labels were found to be substitutes. In addition, organic and green labels could not substitute the enterprise brand, whereas the converse of this relationship was true. Finally, a mutual substitution relationship was observed between hazard-free label and enterprise brand. Our research enables producers to consider the interaction between certification strategies and brand strategies. Therefore, marketers and policymakers should take steps to promote and expand consumers’ knowledge on certification, as it could benefit the development of certified food.
The Limited Role of the Japanese Military: The 2003 Iraq War and the War on the Islamic State
Authors: Boduszyński Mieczysław P. , Lamont Christopher K. , Streich Philip
Published: December 2021

What determines Japan's willingness to flex its limited military muscle abroad? While analysts and scholars closely watched Japanese "militarization" under Prime Minister Shinzo Abe (2012-2020), Japan had already deployed its military overseas over a decade ago in support of U.S. operations in Iraq and Afghanistan. By contrast, in 2014, Japan was unwilling to support U.S.-led operations against the Islamic State (ISIL) in Iraq and Syria. This presents a puzzle, as the fight against ISIL offered the kind of international legitimacy that the 2003 Iraq invasion lacked, and Japan traditionally seeks. Moreover, ISIL had killed Japanese citizens. This paper explains Japan's varying policies in Iraq in 2003 and 2014, thereby shedding light on the determinants of Japanese national security policy more generally. Our argument focuses on domestic political factors (especially the pluralist foreign policymaking) and strategic thinking rooted in realism. We argue that Japanese policies are driven by domestic politics, profound suspicions about the utility of military force and fears of becoming entangled in a seemingly never-ending conflict. While Koizumi may have had more room to manoeuvre despite long-standing public opposition to overseas military deployments when he dispatched the SDF to Iraq in 2003, it is precisely such deeply-entrenched popular anathema that many blame for the Liberal Democratic Party's (LDP) historic and devastating loss in the 2009 election. Abe was unwilling to repeat such a risky venture in 2014. We also highlight the role of realist calculations on both Japanese elites and the public, who by 2014 had come to see China rather than state or non-state actors in the Middle East as a primary security threat. We thus confirm Midford's finding that "defensive realism" tends to drive Japanese foreign policy thinking. Japanese citizens are not pacifists, as conventional wisdom might hold. Instead, Japanese public opinion supports the use of minimum military force when and if Japan is attacked to defend Japan's national sovereignty and territory but is much more suspicious of such power when it comes to deployments and the pursuit of other foreign policy goals.
Márcio Souza e o Judaísmo: a questão das nomenclaturas étnicas na literatura brasileira
Authors: De Carvalho João Carlos
Published: December 2021

A proposta de discussão teórica implica um enfrentamento a partir do conceito de retalhos de memória. A ideia de releituras palimpsésticas produz ao ensaísta o desafio de remexer as pistas invisíveis de sua origem judaica. Nesse caso, ao partir em busca das relíquias do passado, a escrita se lança ao abismo, submetendo-se ao risco de produzir sensações e imagens capazes de conciliar o presente e o passado. O artigo retoma um ensaio de Márcio Souza, “A verdadeira nação de Rafael Bentes”, conhecido autor amazonense, onde ele, sob o foco de (re)encontrar-se com sua judeidade sefaradita, procura evocar as condições de um trajeto, não para descrever o percurso propriamente, mas para possibilitar o testemunho de reconstrução, sob a égide benjaminiana, relido à luz da dinâmica de produção do sensível ao próprio discurso histórico e memorial.

Partindo da leitura pioneira feita por Antonio Candido em “O homem dos avessos”, o presente artigo propõe um passeio por quatro leitores de Grande sertão: veredas, de Guimarães Rosa – Antonio Candido, João Adolfo Hansen, Vilém Flusser e Willi Bolle – à luz de certa antropologia recente, representada aqui por Eduardo Viveiros de Castro. O objetivo do trabalho é investigar como os críticos, em suas estratégias de investigação, se valem da oposição “natureza/cultura”, e diversos de seus desdobramentos, para suas análises do romance rosiano. Em última instância, busca-se apontar a insuficiência da forma como certa metafísica ocidental costuma ser operada para tentar dar conta do romance.

This paper described and contextualized participatory development of demand-driven curriculum for career-ready e-extension services in Nigeria as introduced by the Sasakawa Africa Fund for Extension Education. The stages of participatory development were participatory need assessment, participatory stakeholders’ workshop and validation among 124 stakeholders selected as key informants in relation to agricultural extension training, delivery, end users and policy makers. The stakeholders were grouped as follows: community leaders and policy makers; extension agencies / organisations / institutions / employers; farmers; input suppliers / marketers / agro-based traders / other value actors; and potential candidate groups. Stakeholder meetings were held separately with different groups three times, and then a combined meeting took place. The aggregated major decisions/consensus were subjected to content analysis using ATLAS.ti. The validation process included reading of each agreed decision to all participants, then participants indicated their agreement or otherwise, which led to either rejection or acceptance of the decision. This paper concludes that participatory curriculum development has enhanced the stakeholders to identify areas of demand-driven training in response to community needs. The stakeholders preferred more online than face-to-face training. The major perceived advantages of e-extension were reduced risk, time and cost effectiveness while infrastructural and human challenges were the perceived challenges that could possibly hinder the smooth running of e extension.
Game perception in primary school teachers (Isparta example)
Authors: Akinci Abdullah Yavuz , Yildirim Mehmet
Published: December 2021

The aim of this research is to reveal the attitudes of primary school teachers about the participation of primary school students in the game, how the classroom teachers perceive the game, how they interpret the relationship between the game and the child, and how they evaluate the game in line with the curriculum. In the 2020-2021 academic year, 343 primary school teachers selected randomly among 1230 primary school teachers working in primary schools affiliated to the Isparta Provincial Directorate of National Education participated in the study. Google Forms platform was used for data collection. This method has been preferred to maintain social distance during the pandemic process. As a result, it has been understood that teachers have an important role in the students' ability to benefit from the game sufficiently, and it is thought that the differences seen in the sub-dimensions are due to the differences in the nature of the information, its origin and accuracy, understanding and evaluation, change, and the perceptions of the teachers in the processes of producing and acquiring information.

Over the years, traffic safety has been taught and has become a common subject in Vietnamese primary schools. Educational activities take place in both formal and extra-curricular educational activities. However, traffic safety education and management of traffic safety education in schools have not received adequate attention. Implementation activities are still formal, have not shown continuity, long-term and drastic; the coordination with other educational forces is not synchronized, etc. Therefore, the effect achieved in traffic safety education in schools is not high. Aware of the importance of this activity, based on the actual survey in 04 selected primary schools, with 84 people being administrators and teachers; The study focuses on analyzing the current situation, necessity, and problems posed in traffic safety education management activities in primary schools.

This article aims to identify the peculiarities of the higher education pedagogy transformation through the blended learning model. The methodology was based on a statistical, correlational analysis by using The Teaching and Learning International Survey database containing the survey results of 7,823 educators in France and the Netherlands. The study revealed an average level of teacher preparation for blended learning (50.5%) and preparation for information and communication technology (ICT) use in student learning (48.4%) components inclusion. A significant level of teachers’ professional development of ICT skills was revealed (44% take courses). An average level of teachers’ unpreparedness both for blended learning (28.9% not ready, 36.6% not prepared enough) and ICT use in practice was established (30.3% almost not ready, 34.25 not prepared enough). A positive correlation was established between the teachers’ preparation for the blended learning environment and the passage of professional ICT skills development courses.
Pacioli's Lens: Through a Glass, Darkly
Authors: Macve Richard H.
Published: December 2021

It has long been argued that double-entry bookkeeping (DEB) was important for enabling capitalism's development in the West and heralded the beginning of “modern accounting.” However, these claims remain contested so it is important to understand the history of DEB's emergence about 700 years ago and its underlying rationale. Sangster (2018a) argues that, in the first printed manual on DEB in 1494, Pacioli presented a novel “axiomatic” approach to explaining DEB that requires a corresponding “paradigmatic shift” in our appreciation of his contribution. This paper challenges Sangster's interpretation of Pacioli's mathematical contribution and calls for deeper understanding of the historical development of DEB in the West by comparison with accounting developments in the East.

Bireysel Isıtma Sistemlerinde Tesisat Temizliğinin Enerji Verimliliği Açısından Deneysel Olarak Değerlendirilmesi
Authors: YÜRÜK Muhammet , VARİYENLİ Halil , MARTİN Kerim , KHANLARI Ataollah , AYTAÇ İpek
Published: December 2021

Isıtma sistemlerinde zamanla kireçlenme başta olmak üzere çeşitli sorunlar ve kirlenme meydana gelmektedir. Bu kirlenme radyatörlerin ısı atmasını engelleyerek sistemin verimsiz çalışmasına ve enerji sarfiyatına neden olmaktadır. Bu çalışmada tesisat temizliğinin sağlayacağı enerji verimliliği üzerine deneysel bir araştırma yapılmıştır. Çalışmada tesisat temizliğinden önce ve sonra yapılan ölçüm ve hesaplamalar ile bu iki durum kıyaslanmıştır. Tesisat temizliğinin radyatörde oluşan sıcaklık dağılımını homojenize ettiği görülmüştür. Yapılan temizlik neticesinde radyatör sıcaklıklarında yaklaşık 5°C’lik artışlar elde edilmiştir. Ayrıca doğal gaz tüketiminde % 21.16’lık azalma sağlanırken radyatörlerde gerçekleşen taşınım ısı transfer mekanizmasında da %17.2’lik iyileşme sağlanmıştır. Ayrıca kullanılan doğalgaz miktarına bağlı olarak çevreye salınan zararlı gaz miktarlarında (NO, NOx, CO, CO2 ve O2) % 3.2 ile % 25 arasında değişen oranlarda azaltımlar elde edilmiştir.

Published: December 2021

Objectives

To analyze the biocompatibility of different desensitizers containing casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and fluoride in their composition: MI Varnish (MV), Clinpro White Varnish (3M Oral Care), Profluorid Varnish (VOCO), Duraphat (Colgate) and Embrace Varnish (Pulpdent) on human gingival fibroblast cells (hGF).

Methods and Materials

Human gingival fibroblast (hGF) cells were exposed to several desensitizer extracts at different concentrations (0.1%, 1%, and 4% eluates). Then, in vitro biocompatibility was studied by analyzing the IC50 value, cell proliferation (MTT assay and cell cycle), cell migration (wound healing assay), cell morphology and F-actin content (immunocytofluorescence), and induction of apoptosis/necrosis (flow cytometry). Data were analyzed by one-way analysis of variance (ANOVA) followed by Tukey test.

Results

The lowest cell viability and IC50 were observed in all concentrations of Embrace Varnish-treated hGFs (p<0.001), whereas the highest were exhibited by those treated with Clinpro White Varnish. Similar effects were evidenced when induction of apoptosis/necrosis and cell migration assays were assessed. Finally, MI Varnish, Profluorid Varnish, Duraphat, and Embrace Varnish extracts showed lower numbers of attached cells, some of them with an unusual fibroblastic morphology when cultured with 4% concentration of the varnishes, while Clinpro White Varnish exhibited a similar number of cells with an evident actin cytoskeleton compared to the control group.

Conclusions

The results obtained in this study indicate that hGFs show better in vitro biocompatibility after exposure to Clinpro White Varnish, even at the highest concentration employed, making it the most eligible for topical applications. In contrast, Embrace Varnish exhibited a high cytotoxicity towards hGFs that could potentially delay the healing process and regeneration of the oral mucosa, although more studies are needed to confirm this hypothesis.
