Authors: Ottoman Oscar , Shayo Mary , Elias Edrick , Bhuko Jeffer , Jaka Hyasinta , Reuben Ester
Published: February 2023

Background information: Helicobacter pylori (H. pylori) is one of the major public health problems worldwide, affecting more than 50% of the world’s population. In Tanzania, more than 50% of the population is infected by the H.pylori. Identification of its infection is essential for its eradication. There is no specific method for detection of H. Pylori in gastric tissue biopsy at Bugando Medical Centre (BMC) rather than the routine Hematoxylin and Eosin (H&E) stain which has lower detection rate of 11.2%.
Objective: To determine the histomorphological patterns and H. pylori status of gastric tissue biopsy by Giemsa stain at BMC.
Methodology: This was retrospective cross-sectional study involves 300 gastric tissue blocks from January 2020 to January 2022 archived in histopathology laboratory at BMC. Gastric tissue blocks were sectioned, stained by H&E and Giemsa for histomorphological diagnosis and H. pylori status.
Results:A 300 gastric biopsies were identified, of which 53.75% were males and 46.3% were females. Majority of participants were 40 years and above 202(67.3%), most diagnosed with chronic gastritis 131 (43.7%), followed by gastric adenocarcinoma 115(38.3%), those aged bellow 20 years were only 24(8%). Males were predominantly diagnosed with Gastric adenocarcinoma (35.4%) and Gastric ulcers (4.9%) while majority of females had chronic gastritis (43.2%). by Giemsa stain, H .pylori was detected in only 106(35.3%). The association between H. pylori status with chronic gastritis, gastric adenocarcinoma, gastric polyps, gastric ulcers and gastric perforation were statistically significance (p-value<0.05).
Conclusion: By the use of Giemsa stain, H. pyloriwas detected in about one third of gastric tissue biopsy. Most of gastric tissue biopsy with H. pyloriinfection were those with chronic gastritis. H pylori infection was associated with chronic gastritis, gastric adenocarcinoma, gastric ulcers, and gastric perforation. More studies focus on molecular pathogenesis of H.pylori on cause of various cancer disease like adenocarcinoma and MALT lymphoma is recommended in Mwanza, Tanzania.
Multi-Product Quantity Discount
Authors: Liu Zuofeng
Published: February 2023

For products with different quantity discount strategies, the seller needs to manually unify the products’ discount strategies for a multi-product quantity discount. In addition, the quantity discount in current practice often fails to give reasonable quantity discounts for multiple products. Is it possible to develop an algorithm to automatically and efficiently provide more reasonable multi-product quantity discounts while keeping each product's quantity discount strategy unchanged? This is what the authors achieved via a brand-new approach in this paper. According to the nature of quantity discount, the quantity of products should have a consistent logic with the products' prices, that is the more purchases, the higher the total discount price and the higher discount on each product that does not reach its maximum discount. And it can be assumed that the traditional discrete quantity discount should also follow this nature, it is just due to no algorithm support or the interest consideration that sellers follow the nature only on discrete discount thresholds and adopt traditional results on the other quantities. Along this line of thought, the authors define for the first time the multi-product quantity discount that can be applied to multiple products with different discount strategies, and use the rigorous mathematical method to complete the development of the algorithm which supports the continuous quantity discount and the discrete quantity discount that cover the traditional discrete quantity discount.
Dynamic modulation of synaptic transmission in the mouse ACC by inflammatory pain and dopamine
Authors: Darvish-Ghane Soroush , Buambach Jennet , Martin Loren J.
Published: February 2023

Dopamine (DA) inhibits excitatory synaptic transmission in the anterior cingulate cortex (ACC), a brain region involved in the sensory and affective processing of pain. However, DA modulation of inhibitory synaptic transmission in the ACC and its alteration of excitatory/inhibitory (E/I) balance remains relatively understudied. Using patch-clamp recordings, we demonstrate that DA inhibits γ-Aminobutyric acid subtype A (GABAA) receptor-mediated evoked inhibitory currents (eIPSCs) through postsynaptic D2 receptors. Recording excitatory and inhibitory currents from the same neuron yielded a heterogenous response dominated by GABAergic transmission. However, complete Freund’s adjuvant (CFA), a model of inflammatory pain, reduced the percentage of neurons showing synaptic inhibition by DA in the ACC. These results indicate that inflammatory pain induces changes in the interplay between DA signalling and inotropic transmission in the ACC of mice.

Published: February 2023

In the United States, about 26% of the population reports having some form of disability. However, people with disabilities (PwD) are under-represented in science, technology, engineering, and mathematics (STEM). The representation of PwD as patented inventors is unknown, but likely
under-represented, given their limited numbers in STEM and the workplace. This study set the goal of identifying PwD with patented technologies that have also been introduced into the marketplace. Using web searches and patent awards/applications, 21 influential inventors with disabilities
were identified. The impact of these inventors was assessed and is briefly described. Technologies that were invented for PwD that have had mainstream success were also identified. Inventors with disabilities have made important contributions, but further study is required, as the inclusion
of PwD in the inventor community is a nascent field of study that is important for expanding the innovation community.

In the advent of the rapid technological advancement of The Fourth Industrial Revolution (4IR), computational thinking is recognised as an essential skill in the 21st century across all disciplines, especially in STEM, as it trains students to have the cognitive flexibility to deal with complex problem-solving. Computational thinking (CT) is naturally embedded in STEM practices in the reflection of creativity, algorithmic thinking, critical thinking, problem solving and cooperation skills. This study aimed to measure the level of computational thinking in science matriculation students and examine the effect of gender and academic achievement in STEM on CT. The convenient sampling strategy was used to identify one matriculation college in the northern region of Malaysia to participate in the study. (CTS) instrument was employed on 153 science students. Descriptive analysis was used to evaluate the level of CT. One-way multivariate analysis of variance (MANOVA) was performed to analyse the main effect of academic achievement in STEM on CT, followed by univariate analysis of variance (ANOVA) to determine the effect on each of the dimensions of CT. The result indicates that students have a medium high level of CT with an overall mean of 3.51. In addition, the findings showed that there was a statistically significant effect of academic achievement in STEM on CT. The mean score for academic achievement revealed that good students scored the highest, followed by average students and weak students in all dimensions of CT except for cooperation. This study will provide insight into the impact of STEM learning outcomes on the development of CT to inform instructional design.
Financial remittances and election turnout in the municipalities of the Republic of Serbia: the economy of voting
Authors: Milovanović Miloš
Published: February 2023

This paper investigates possible evidence on whether remittances from abroad have had a significant influence on the outcome of Serbia’s presidential elections. Using the linear random-intercept model and based on presidential- election data for municipalities between 2002 and 2017, the study finds that voter turnout rates were positively related to the share of remittances in the municipalities’ GDP per capita. For a 1% increase in the share of remittances in municipalities’ GDP, the voting turnout increases by 0.31% on average. Also, regarding the within-municipality effect, as the share of remittances in GDP increases over time by 1%, voter turnout decreases by 0.42%. Further, it reveals how the size of the population temporarily abroad had a negative effect on voter participation throughout the entire period examined across both municipalities and time. The study also captures the effects of education and ethnicity. Specifically, as the share of highly educated people increases by 1% over time, so the election participation rates in a particular municipality also increase by 0.83%. After introducing categorical variables for the ethnic composition of the municipality, the study finds that in municipalities with a non-Serb majority, the level of participation was on average 3.31% lower, from 2002 to 2017. Finally, a statistically significant difference in voter turnout was recorded between the economically most developed and the least developed regions: the most developed region had on average 7.71% higher election participation than the region characterized by high emigration and large financial inflows. As far as Serbia is concerned, the final results confirm the findings of previous literature that the economical vacuum, created by the disappearance of state support, is filled by remittances. Possible reasons for the results are discussed.

Research on Motion Control Optimization of Quadruped Crawling Robot
for Continuous Slope
Authors: Zhang Peng , Wang TianYu , Dong Ren Quan , Liu XiuLian , Wang Peng
Published: February 2023

Background:

In recent years, literature has suggested that quadruped crawling robots
have been widely used in the field of reconnaissance on rugged mountain trails. Under the influence
of gait and slope, the joint angle of the robot changes drastically when landing, resulting in
the robot drop down from the slope. This has strict requirements for gait planning and gait control
of quadruped crawling robots.

Objective:

The aim of this study is to set up a novel impedance controller based on gearshift integral
PID to improve the stability of a quadruped crawling robot during climbing on a continuous
slope.

Methods:

The three-dimensional model of quadruped crawling robot was established. Considering
the characteristics of slope terrain, a slope diagonal gait design is proposed, and a gearshift integral
PID impedance controller is designed for this gait. The impedance controller based on position
PID, integral separation PID and gearshift integral PID is simulated by MATLAB, and the peak
value of foot force is compared under ADAMS.

Results:

Overshoot and transient time of positional PID impedance controller was compared, integral
separated PID impedance controller and gearshift integral PID impedance controller, the overshoot
was reduced by 8.9% and the transient time was reduced by 20%. Finally, the position impedance
controller that meets the requirements and import it into ADAMS to compare the peak
foot force was selected, it reduced the foot-end contact force by 8.15%.The results show that the
gearshift integral PID impedance control strategy is feasible.

Conclusion:

The Impedance controller based on gearshift integral PID can provide a reference for
other impedance control strategies of quadruped crawling robots.
Hyperbranched Nanostructure Drug Delivery Carrier: Dendrimer
Authors: Mishra Sudhanshu
Published: February 2023

Dendrimers are nanosized macromolecules with a hyperbranched globular shape that are commonly
employed for drug delivery. They have shown to be both complex and valuable due to their high
level of surface functioning, adaptability, and unique features. Furthermore, dendrimers have a wide
range of applications in supramolecular chemistry, mainly in self-assembly processes. The potential of
this macromolecule to construct a definite architectural design in terms of size, shape, branching length,
density, and its well-defined molecular structure and segmented spherical construction has sparked a wide
range of research on the interactions that occur between biological organisms. Dendrimers are "grown"
from a central core in a repetitive divergent manufacturing process, with each succeeding step representing
a new "generation" of the dendrimer. In comparison to linear polymers, dendrimers have more precisely
controlled structures, globular in shape, and have a specific molecular weight rather than a range of
molecular weights. The divergence in dendritic structure customization provides a one-of-a-kind framework
for drug delivery to acute and chronic diseases. The development of efficient drug delivery systems
based on dendrimers has attracted much interest in recent years. This review aims to discuss some important
perspectives and recent patents regarding dendrimers.
La instrumentalización del saber antropológico en la década de 1930 en el marco de la colonización de los Llanos Orientales
Authors: Reyes Gavilan Aura Lisette
Published: February 2023

Este artículo aborda un estudio de caso en el que la etnografía y los proyectos de colonización en Colombia se entrelazan a través de las políticas gubernamentales de la década de 1930. Se analiza el trabajo del etnólogo sueco Gustaf Bolinder, quien fue contratado por el Gobierno colombiano en 1935 con el fin de realizar una investigación etnográfica en los Llanos Orientales, elaborar un manual para los trabajadores del Gobierno, preparar una serie de conferencias sobre etnografía y arqueología, y conformar una colección de objetos etnográficos para el Ministerio de Educación.
Los planteamientos presentados en este artículo parten de una investigación documental en diferentes archivos, materiales poco explorados por los estudios de la historia de la antropología colombiana. Asimismo, el caso se analiza en el marco del desarrollo de una antropología estatal que precede a la institucionalización disciplinar en la década de 1940.
Del empoderamiento popular a las gobernanzas criminales
Authors: Cardozo-Uzcátegui Alejandro
Published: February 2023

El artículo ofrece un análisis del concepto de empoderamiento (empowerment) popular y de su acepción latinoamericana de potenciación popular. A partir de un análisis casuístico y discursivo de Hugo Chávez y el chavismo, se examinan los errores epistemológicos y empíricos en el uso de este concepto desde los albores de la revolución bolivariana o chavista, para comprender cómo la transición hacia un modelo de democracia participativa y, por ende, de empoderamiento popular resulta en gobernanzas criminales. Este resultado se deriva de la naturaleza clasista del discurso de Chávez, en el que se criminaliza la condición burguesa de sectores medios y altos de la sociedad venezolana.

Waterpipe tobacco smoking (WTS) is a traditional tobacco use method that originated in the Eastern Mediterranean Region (EMR) and has resurged in recent decades. WTS rates in the EMR are the highest worldwide, especially among youth, exceeding cigarette-smoking rates in select jurisdictions. Despite its documented harm, the growing prevalence of WTS has been met with a poor regulatory response globally. At the epicenter of the WTS epidemic, countries in the EMR are in urgent need of effective tobacco control strategies that consider the particularities of WTS. A roundtable session, titled “Monitoring and Combating WTS Through Taxation and the Global Tobacco Surveillance System (GTSS),” was held as part of the 7th Eastern Mediterranean Public Health Network’s regional conference. The session provided an overview of evidence to date about WTS policy control, the taxation of WTS, volumetric choice experiments for tobacco control research, and monitoring WTS patterns and control policies among adults and youth through the GTSS. The session highlighted the need to update the regulation of WTS in the current global tobacco control policy frameworks and the need for developing tailored, evidence-based, and WTS-specific regulations to complement current tobacco control policy frameworks. Raising taxes to increase the price of tobacco products is the single most effective tobacco control measure, and these taxes can fund expanded government health programs. The effectiveness of taxation can be measured via volumetric choice experiments, which allow for the estimation of a complete set of own-price and cross-price elasticities that are instrumental for fiscal policy simulations. Finally, the surveillance of WTS (for example, through the GTSS) is critical to informing policy and decision makers. The Global Youth Tobacco Survey (GYTS) and Global Adult Tobacco Survey (GATS) are 2 GTSS products that provide nationally representative data among students aged 13-15 years and persons ≥15 years, respectively.

Authors: Stoikevich M.V. , Karachynova V.A. , Klenina I.A. , Petishko O.P.
Published: February 2023

Background. Pathogenetic factors that cause the development of inflammatory bowel diseases (IBD) remain poorly understood, namely, the peculiarities of saturated fatty acids (SFAs) in the blood serum at different degrees of disease severity, which is quite an important task. Objective: to evaluate serum level of SFAs depending on IBD severity. Materials and methods. Thirty-seven patients with IBD were examined, their average age was (38.5±2.1) years. Depending on the severity of the disease, the patients were divided into 2 groups: group I— with IBD of moderate severity (n=24) and group II— with severe IBD (n=13). The control group consisted of 16 healthy people. The quantitative content of SFAs in the blood serum of the examined patients was determined by gas chromatography. Median (Me), lower (25%) and upper (75%) quartiles were used to describe the data. Results. Biochemical analysis revealed a tendency to decrease in the level of short-chain SFA (butyric acid; p>0.05) and a significant increase in the total content of medium- and long-chain SFAs (MCSFAs and LCSFAs; p<0.001) in the serum of group I and II patients compared to the controls. It was found that with increasing severity of IBD, there was a decrease in LCSFAs content in the blood (r=–0.420, p=0.048). The serum spectrum of SFAs was analyzed and a significant increase in all MCSFAs fractions was detected in both groups of patients: caproic acid (p<0.001), caprylic acid (p<0.001), capric acid (p≤0.002), undecylic acid (p≤0.006) and lauric acid (p≤0.001). Characteristically, the content of the most MCSFAs fractions had a tendency to decrease (p>0.05) in group I against group II of patients. The content of LCSFAs, namely: tridecylic acid (p≤0.012), myristic acid (p<0.001), pentadecylic acid (p≤0.012), palmitic acid (p<0.001), stearic acid (p≤0.001) and heneicosylic acid (p<0.001), increased significantly in group I and II of patients, while the content of margaric and eicosanoic acids— only in group I compared to the controls. Almost all LCSFAs (except tridecylic acid) had a tendency to increase in group I against group II. Conclusions. It has been shown that the content of SFAs in the blood depends on the degree of IBD severity. The mechanism of SFAs action with different carbon chain lengths is multidirectional and is associated with the effect on pro-/anti-inflammatory mediators and with the maintenance of the immune and intestinal homeostasis. The necessity of determining serum SFAs in IBD to correct the identified disorders has been confirmed.

Published: February 2023

The article deals with chronic inflammatory processes of the intestines and their complications that contribute to the gradual accumulation of deep transmural lesions of the intestinal wall, including narrowings, development of obstruction, abscesses, and fistulas. Both inflammatory bowel diseases and their chronic complications lead to the onset of diarrhea, abdominal pain, anemia caused by intestinal pathology. Detecting the disease activity and complications severity is of crucial importance in the treatment intensity at early and later stages of the illness and when monitoring treatment measures effectiveness. The main molecular mediators of fibrogenesis are studied in the article, the results of development of intestinal fibrosis visualization technologies are summarized, possibilities for expanding the quantitative magnetic resonance imaging, computed tomography, ultrasound and encouraging potential of non-invasive elastography methods are discussed.
Perdebatan Perspektif Transisi dalam Kajian Kepemudaan
Authors: Sutopo Oki Rahadianto
Published: February 2023

Artikel ini membahas mengenai perdebatan perspektif transisi dalam kajian kepemudaan. Dengan menggunakan studi pustaka, artikel ini menjelaskan empat hal yaitu terkait transisi berdasarkan umur vs dimensi sosiologis, terkait dengan dilema struktur-agensi, terkait dengan transisi vs generasi, relevansi interseksionalitas dalam kajian empiris transisi pemuda di Indonesia serta kemungkinan mewujudkan perspektif transisi yang berspirit dialog global. Penggunaan perspektif yang tunggal tidak memungkinkan dalam memahami transisi kaum muda Indonesia kontemporer. Hasil analisis dalam artikel ini justru mengusulkan mengenai pentingnya interseksi berbagai macam variabel baik kelas sosial, gender, spasial, generasi dan perubahan, serta aplikasinya dalam konteks sosio-kultural-historis yang baru. Dalam artikel ini juga dijelaskan mengenai pentingnya perspektif transisi melakukan kontekstualisasi pada pengalaman kaum muda Indonesia sebagai bagian dari Global South, memunculkan narasi-narasi kaum muda terpinggirkan dengan prinsip epistepraxis sekaligus membangun dialog dalam rangka membangun kesepahaman transisi kaum muda sebagai manifestasi dari generasi muda global. This article examines the debates of youth transition perspective in youth studies. Using library research, this article explores four aspects related to youth transition perspective: firstly, the debates between age cohorts and sociological dimension of transition; secondly, the dilemma between structure and agency; thirdly, ongoing debates between transition versus generations, and lastly, the relevance of intersectionality in the empirical studies of youth transition and its chance to develop youth transition with a spirit of global dialogue. In this article, I also argue that it is impossible to understand the complexities of youth transition only with one perspective as a tool of analysis. In contrast, I suggest on the importance of intersections between class, gender, spatiality, generation and social change as well as critical contextualisation in the new socio-cultural-historical context. In this article, I also suggest the importance of contextualisation of youth transition perspective based on the lifeworld of Indonesian youth as a part of Global South countries, raising the voices of marginalized youth using concept of epistepraxis, as well as set up dialogues in order to build understanding on the experiences of young people’s transition as a manifestation of global youth generation.

Published: February 2023

Abstract: Biotechnology is the exploitation of biochemical potential of the microorganisms for the medical, agricultural and industrial purposes. In processing, either the microorganisms are eliminated to prevent spoilage or they are encouraged to grow resulting in the production of fermented products. This study deals with the operating condition and comparison of enzyme production and purification of α-amylase from mutated and non- mutated Aspergillus tamarii. α- Amylase is an extracellular enzyme which can be produced by Aspergillus tamari using solid state and submerged fermentation. In the submerged fermentation, the α-amylase production was started after 24hrs and the maximum production was achieved after 7 days, but in the solid state fermentation the production was initiated after 3 days and the maximum production is observed after 12 days. The commercial medium used for the α-amylase production is sweet potato soluble starch. The pH for the solid state fermentation should be maintained at 4±0.2 and for the submerged process the pH should be at 7.0±0.2. The maximum yield of enzymes was achieved using submerged fermentation.

Exploring the educational paradigm shift to create a dynamic relationship between artificial intelligence and human beings: Focusing on artificial intelligence secondary textbook analysis
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kim JiYeon , Kim SeongHee
Published: February 2023

Objectives This study aims to analyze the bias problem of modern science, such as technological determinism contained in artificial intelligence secondary education textbooks, through the theoretical concept of Science and Technology Studies (STS).
Methods This study was largely conducted by (1) the survey of public perception of artificial intelligence education and (2) the analysis of contents of current high school artificial intelligence textbooks. A survey method was applied for public perception, and a qualitative analysis was applied for textbook analysis.
Results Through the analysis of artificial intelligence textbooks, it was possible to examine (1) technological determinism, (2) gender bias and labor bias, and (3) ethically dangerous contents in artificial intelligence textbooks. These biases and risks divide the relationship between artificial intelligence and human actors in a dichotomous way and limit it to economic aspects, and in the end will prevent a dynamic relationship of both and lead to a rigid or hate.
Conclusions Our society tends to limit science & technology textbooks to vocational education use only. Future generations will face unexpected situations while living in conditions where information/data/artificial intelligence are generalized. The main goal of AI curricula should be for civic education, not just only for job-seeking. Citizens in the era of artificial intelligence should be dynamic and participatory users (subjects), not simply passive labors or consumers. In line with this, additional diagnosis and improvement of current artificial intelligence textbooks and curricula are needed.

Published: February 2023

Caesalpinia ebano is a tropical tree from Colombia; its conservation status is in the endangered category since the remaining populations are suffering genetic erosion. The objective of this study was to estimate the phenotypic (rF) and genetic (rG) correlations among biometric fruit and seeds traits, and the path analysis for the fruit weight. Ten trees (treatments) were evaluated under the random effects model, with 10 fruits/tree as replications. There was significant variability between trees for seven quantitative traits. The fruit weight showed genetic correlations with six traits (0.56* > rG < 1.00**). The number and weight of the seeds per fruit showed high genetic correlations with five traits (rG ≥ 0.85**). The weight of the seeds per fruit exerted direct and indirect effects of greater importance in determining the fruit weight. It is possible to improve the production and physiological quality of the seed by directly selecting trees with fruits of greater seed weight.

Broad bean cultivation is considered a productive strategy and a component of food sovereignty in Southern Colombia. Therefore, this study was carried out in order to evaluate twelve promising genotypes and two commercial controls, to expand the improved varieties supply of this legume in the future. For this, an experimental assay was established with 14 treatments and four repetitions. Where, 13 agronomic traits and the reaction to the pathogen Botrytis fabae were estimated. The information was analyzed by a simple ANOVA test. Also, a Principal Component Analysis (PCA) was developed with the traits with the highest coefficient of variation. Results showed genetic diversity, with promising genotypes in relation to the controls. The number of stems, flowering days, pod formation days, pods per plant, weight of one hundred seeds, and yield allowed three groups to be identified by PCA. The first one was made up of two controls, the second group characterized by higher yields, and a third group represented by an intermediate yield added to an earliness condition. These results allow the recognition of candidate genotypes to be included into breeding programs and contribute to the crop protection.

The rate of increase tea cost production in several tea fields could not be offered by the rate of increase selling price. The fact that the cost of plucking machine is lower than manual plucking has attracted the interest and attention of tea smallholder to change from manual plucking to plucking machine. The plucking machine which were imported from japan was not designed for assamica tea in Indonesia. In order to improving performance of plucking machine, the plucking machine need to be designed with support from the field and Â appropriate machine. The aim of this trial was to test the performance of the plucking machine type-120 at plucking of assamica tea with 120 cm of spacing between rows. The plucking type used was medium plucking and kept the Kepel leaves (k +0) in the middle of the bushes using plucking method supported by the garden and the appropriate plucking machine type-120. Results obtained from the test were: (1) The using of plucking machine type-120 with medium plucking, kept the Kepel leaves (k +0), and controlled plucking height did not cause a decrease in plant health, production as well as quality of the shoots. (2) Field work capacity of plucking machine was 1.19 ha/day with work efficiency of 58.2%. (3) The ratio of plucking machine was 0.30/ha with fuel ratio of 0.33 litres/ha. The performance output of the plucking machine could be reached 224 kg/plucker as compared to only 24 kg/plucker when done manually.

Carbon dioxide (CO2) concentration is the most important greenhouse gas in the atmosphere that significantly contributes to global warming. It is important to determine the yearly trend that contributes to the reduction of CO2. In this study, we considered the monthly average of the CO2 concentration in the atmosphere of Mongolia and calculated the correlation coefficient as a function of ‘MODIS’ ‘NDVI’, air temperature, and wind speed. As shown in the results of a study the annual trend of CO2 concentrations was inversely related to ‘NDVI’ (R=-0.87, p<0.001) and temperature (R=-0.67, p<0.05), whereas directly related to wind speed (R=0.91, p<0.001). CO2 concentration has seasonal fluctuations, while vegetation cover plays an important role in the emission and absorption of natural carbon, and is the main factor in the seasonal fluctuations of terrestrial CO2. Furthermore, we calculated the Tayle-Sen slope, CO2 concentration (Q=2.31 ppm/year, p<0.001), ‘NDVI’ (Q=0.002 units/year, p<0.05), air temperature (Q=0.1°C/year, p<0.01) and wind speed (Q=0.01m/s/year, p>0.05) have increased over the last 11 years. However, compared to the p-value, the temperature is not higher than the CO2 concentration. CO2 concentration has increased throughout all seasons. ‘NDVI’ was less significantly comparable to CO2 and temperature, while wind speed was increased but it is not significantly. This increase in CO2 concentration affects spring temperatures and allows plants to start growing earlier. As a result, ‘NDVI’ values increased significantly in the spring season during the study period.

Stress is a common occurrence in daily life; sometimes, it will be a reaction or sometimes a stimulus. The aim and objective of the study were to assess the stress level among old age people and the effectiveness of dance therapy in reducing stress. "The research design selected for the study was pre-experimental one group pre-test and post-test research design". A non-probability convenience sampling technique was used to obtain a sample of 60 old age people who satisfied the inclusion criteria. The modified psychological stress assessment scale, a standardized measure for assessing the stress level among old age people, was administered to conduct the pre-test and the post-test. This tool contains 30 items. This is a 4-point scale, and the total score is 90. After assessing the pre-test stress level, dance therapy was provided to each sample for 30 days for 45 minutes per day each morning. After 30 days, stress was measured using the same modified psychological stress assessment scale. The Mean of the pre-test and post-test was (61.05) and (25.85), and the Standard Deviation of the pre-test and post-test was (11.89) and (8.27). The Mean difference was (35.2). This showed that there was a significant difference between pre-test and post-test levels of stress scores among old age people. The calculated chi-square value was significant with age, educational status and duration of stay at nursing homes; other variables were not significant. From the study results, it was concluded that Dance Therapy effectively reduced the stress level among geriatrics.
Relações institucionais e programação de filmes: o caso do Centro Cultural São Paulo e da Cinemateca Brasileira entre os anos de 1982 e 1985
Authors: Timoteo de Mamede Liciane
Published: February 2023

No presente artigo, procuramos abordar de que maneira a programação da sala de cinema Lima Barreto, no Centro Cultural São Paulo, em seus três primeiros anos (1982-1985), reflete as relações institucionais existentes entre a Fundação Cinemateca Brasileira e a Prefeitura de São Paulo, por meio da então recém-criada Secretaria Municipal de Cultura. Dessa maneira, pretendemos esboçar uma melhor compreensão sobre por que a Cinemateca esteve, num primeiro período, tão envolvida com a programação do centro cultural, mas logo acabou se afastando. Também nos interessa tratar aqui do conteúdo dessa programação e do contexto cultural envolvendo o circuito de exibição cinematográfico naquele momento na cidade de São Paulo, a fim de tentar entender os caminhos tomados pelo setor de programação de cinema do Centro Cultural, a partir de seu distanciamento da Cinemateca Brasileira.
