Computational Modelling for Electrical Impedance Spectroscopy-Based Diagnosis of Oral Potential Malignant Disorders (OPMD)
Authors: Heath James P. , Hunter Keith D. , Murdoch Craig , Walker Dawn C.
Published: August 2022

A multiscale modelling approach has been applied to the simulation of the electrical properties of oral tissue, for the purpose of informing an electrical impedance-based method of oral potential malignant disorder (OPMD) diagnosis. Finite element models of individual cell types, with geometry informed by histological analysis of human oral tissue (normal, hyperplastic and dysplastic), were generated and simulated to obtain electrical parameters. These were then used in a histology-informed tissue scale model, including the electrode geometry of the ZedScan tetrapolar impedance-measurement device. The simulations offer insight into the feasibility of distinguishing moderate dysplasia from severe dysplasia or healthy tissue. For some oral sites, simulated spectra agreed with real measurements previously collected using ZedScan. However, similarities between simulated spectra for dysplastic, keratinised and non-dysplastic but hyperkeratinised tissue suggest that significant keratinisation could cause some OPMD tissues to exhibit larger than expected impedance values. This could lead to misidentification of OPMD spectra as healthy. Sources of uncertainty within the models were identified and potential remedies proposed.
Typical Fragment Kinetic Energy Assessment Based on Acoustic Emission Technology
Authors: Shang Fei , Wang Liangquan
Published: August 2022

Fragment kinetic energy is an important parameter to characterize the damage power of fragments. In this study, an acoustic emission technology-based method to evaluate fragment kinetic energy is proposed. The dynamic response of the fragment impacting an aluminum alloy target plate and the relationship between the initial kinetic energy of the fragment impact and the acoustic emission waveform were theoretically evaluated; the numerical simulation of typical spherical fragments (8 mm diameter) penetrating the aluminum alloy target plate was performed, the wavelet energy of the acoustic emission signal was obtained using wavelet packet theory, and a mathematical model of wavelet energy and fragment kinetic energy was constructed. A fragment kinetic energy test system was established, and a fragment penetration test was performed. The analysis showed that the wavelet energy mathematical models and the fragment kinetic energy exhibited favorable consistency, and the measurement errors of the three experiments were 3%, 3.7%, and 3%. This demonstrates the effectiveness of the typical acoustic emission fragment kinetic energy test methods proposed in this study and establishes a new method for the direct measurement of fragment kinetic energy.
Simultaneous LTE Signal Propagation Modelling and Base Station Positioning Based on Multiple Virtual Locations
Authors: Cho Seong-Yun
Published: August 2022

In the Long Term Evolution (LTE) system, the Signal Propagation Model (SPM) and the location information of the base stations are required for positioning a smartphone. To this end, this paper proposes a technique for estimating the SPM and the location of the base station at the same time using location-based Reference Signal Received Power (RSRP) information acquired in a limited area. In the proposed technique, multiple Virtual Locations (VLs) for a base station are set within the service area. Signal propagation modelling is performed based on the assumptions that a base station is in each VL and the RSRP measurements are obtained from the corresponding base station. The residuals between the outputs of the estimated SPM and the RSRP measurements are then calculated. The VL with the minimum sum of the squared residuals is determined as the location of the base station. At the same time, the SPM estimated based on the corresponding VL is selected as the SPM of the base station. As a result of the experiment in Seoul, it was confirmed that the positions of seven base stations were estimated with an average accuracy of 40.2 m.

Published: August 2022

The accurate and timely identification of the degree of building damage is critical for disaster emergency response and loss assessment. Although many methods have been proposed, most of them divide damaged buildings into two categories—intact and damaged—which is insufficient to meet practical needs. To address this issue, we present a novel convolutional neural network—namely, the earthquake building damage classification net (EBDC-Net)—for assessment of building damage based on post-disaster aerial images. The proposed network comprises two components: a feature extraction encoder module, and a damage classification module. The feature extraction encoder module is employed to extract semantic information on building damage and enhance the ability to distinguish between different damage levels, while the classification module improves accuracy by combining global and contextual features. The performance of EBDC-Net was evaluated using a public dataset, and a large-scale damage assessment was performed using a dataset of post-earthquake unmanned aerial vehicle (UAV) images. The results of the experiments indicate that this approach can accurately classify buildings with different damage levels. The overall classification accuracy was 94.44%, 85.53%, and 77.49% when the damage to the buildings was divided into two, three, and four categories, respectively.

Authors: Taylor Zoe , Walsh Gregory S. , Hawkins Hannah , Inacio Mario , Esser Patrick
Published: August 2022

Background: Despite extensive literature regarding laboratory-based balance perturbations, there is no up-to-date systematic review of methods. This systematic review aimed to assess current perturbation methods and outcome variables used to report participant biomechanical responses during walking. Methods: Web of Science, CINAHL, and PubMed online databases were searched, for records from 2015, the last search was on 30th of May 2022. Studies were included where participants were 18+ years, with or without clinical conditions, conducted in non-hospital settings. Reviews were excluded. Participant descriptive, perturbation method, outcome variables and results were extracted and summarised. Bias was assessed using the Appraisal tool for Cross-sectional Studies risk of bias assessment tool. Qualitative analysis was performed as the review aimed to investigate methods used to apply perturbations. Results: 644 records were identified and 33 studies were included, totaling 779 participants. The most frequent method of balance perturbation during gait was by means of a treadmill translation. The most frequent outcome variable collected was participant step width, closely followed by step length. Most studies reported at least one spatiotemporal outcome variable. All included studies showed some risk of bias, generally related to reporting of sampling approaches. Large variations in perturbation type, duration and intensity and outcome variables were reported. Conclusions: This review shows the wide variety of published laboratory perturbation methods. Moreover, it demonstrates the significant impact on outcome measures of a study based on the type of perturbation used. Registration: PROSPERO ID: CRD42020211876.

Published: August 2022

Hydrogen sulfide (H2S) is known to participate in bacteria-induced inflammatory response in periodontal diseases. Therefore, it is necessary to quantify H2S produced by oral bacteria for diagnosis and treatment of oral diseases including halitosis and periodontal disease. In this study, we introduce a paper-based colorimetric assay for detecting bacterial H2S utilizing silver/Nafion/polyvinylpyrrolidone membrane and a 96-well microplate. This H2S-sensing paper showed a good sensitivity (8.27 blue channel intensity/μM H2S, R2 = 0.9996), which was higher than that of lead acetate paper (6.05 blue channel intensity/μM H2S, R2 = 0.9959). We analyzed the difference in H2S concentration released from four kinds of oral bacteria (Eikenella corrodens, Streptococcus sobrinus, Streptococcus mutans, and Lactobacillus casei). Finally, the H2S level in Eikenella corrodens while varying the concentration of cysteine and treatment time was quantified. This paper-based colorimetric assay can be utilized as a simple and effective tool for in vitro screening of H2S-producing ability of many bacteria as well as salivary H2S analysis.
A Novel Reinforcement Learning Approach for Spark Configuration Parameter Optimization
Authors: Huang Xu , Zhang Hong , Zhai Xiaomeng
Published: August 2022

Apache Spark is a popular open-source distributed data processing framework that can efficiently process massive amounts of data. It provides more than 180 configuration parameters for users to manually select the appropriate parameter values according to their own experience. However, due to the large number of parameters and the inherent correlation between them, manual tuning is very tedious. To solve the problem of tuning through personal experience, we designed and implemented a reinforcement-learning-based Spark configuration parameter optimizer. First, we trained a Spark application performance prediction model with deep neural networks, and verified the accuracy and effectiveness of the model from multiple perspectives. Second, in order to improve the search efficiency of better configuration parameters, we improved the Q-learning algorithm, and automatically set start and end states in each iteration of training, which effectively improves the agent’s poor performance in exploring better configuration parameters. Lastly, comparing our proposed configuration with the default configuration as the baseline, experimental results show that the optimized configuration gained an average performance improvement of 47%, 43%, 31%, and 45% for four different types of Spark applications, which indicates that our Spark configuration parameter optimizer could efficiently find the better configuration parameters and improve the performance of various Spark applications.
Low-Cost Wearable Band Sensors of Surface Electromyography for Detecting Hand Movements
Authors: Gomez-Correa Manuela , Cruz-Ortiz David
Published: August 2022

Surface electromyography (sEMG) is a non-invasive measure of electrical activity generated due to muscle contraction. In recent years, sEMG signals have been increasingly used in diverse applications such as rehabilitation, pattern recognition, and control of orthotic and prosthetic systems. This study presents the development of a versatile multi-channel sEMG low-cost wearable band system to acquire 4 signals. In this case, the signals acquired with the proposed device have been used to detect hand movements. However, the WyoFlex band could be used in some sections of the arm or the leg if the section’s diameter matches the diameter of the WyoFlex band. The designed WyoFlex band was fabricated using three-dimensional (3D) printing techniques employing thermoplastic polyurethane and polylactic acid as manufacturing materials. Then, the proposed wearable electromyographic system (WES) consists of 2 WyoFlex bands, which simultaneously allow the wireless acquisition of 4 sEMG channels of each forearm. The collected sEMG can be visualized and stored for future post-processing stages using a graphical user interface designed in Node-RED. Several experimental tests were conducted to verify the performance of the WES. A dataset with sEMG collected from 15 healthy humans has been obtained as part of the presented results. In addition, a classification algorithm based on artificial neural networks has been implemented to validate the usability of the collected sEMG signals.

Published: August 2022

Rear-end crashes are one of the leading types of crashes today. The anti-lock braking system (ABS) was designed to assist drivers during emergency braking situations by preventing wheel lock up, allowing drivers to retain control of the vehicle. Not all drivers have knowledge and experience with ABS, especially the haptic brake pedal feedback produced by ABS. There studies introduce a new method to train ABS using an emergency braking task on a simulator and an interactive exercise, Pedals Emergency Stop©. The interactive exercise was designed to prompt participants to press the brake pedal in a motion that is consistent with emergency braking and experience haptic ABS feedback. Participants that depressed the brake pedal quickly to the maximum travel and held that pedal position “passed” the trial. In Study 1, participants (N = 63) completed 15 trials, where it took on average three trials to “pass” for the first time, and 85% of the participants experienced their first “pass” within the first four trials. There were no differences observed between participants with previous knowledge and experience feeling ABS versus those who did not have prior knowledge and experience with ABS. The participants in this study thought that they had enough trials, that the exercise was a practical tool, and recommended the task for new drivers and refresher training, as well as for evaluating fitness to drive. Suggested improvements included a practice followed by three tests, all with four trials each; passing criteria of three out of four trials; and modifications to the feedback presented immediately after completing each trail. Study 2 was conducted (N = 38) to investigate the proposed “passing” criteria, where 95% passed on Test 1. The results revealed that the criteria to pass was reasonable. Future research should examine how the Pedals Emergency Stop© interactive exercise generalizes to on-road driving.
Ontological Securitization of Health in Africa: The HIV/AIDS, Ebola and COVID-19 Pandemics and the Foreign Virus
Authors: Kaunert Christian , Ezeokafor Edwin
Published: August 2022

Africa’s security issues have suffered serious attention deficits. This article analyses why a globally accepted health security norm, such as fighting a communicable disease during a pandemic such as the COVID-19 pandemic, was, in Africa, perceived as a security threat emanating from external—foreign—actors importing a ‘foreign virus’ into Africa. This fear-based perception can be explained by West Africa’s ontological security fears, ultimately based on its colonial past and a relationship of exploitation by the West. While this article analyses the case of COVID-19, it also explains the same process with previous epidemics, such as HIV/AIDS and EDV/Ebola.
Genome-Wide Identification of the PYL Gene Family in Chenopodium quinoa: From Genes to Protein 3D Structure Analysis
Authors: Pizzio Gastón Alfredo
Published: August 2022

The halophytic crop Chenopodium quinoa has a remarkable resistance to harsh growth conditions in suboptimal environments and marginal soils. Additionally, quinoa is a pseudocereal and produces seeds with outstanding nutritional value. Quinoa is an allotetraploid (2n = 4× = 36) with an estimated genome size of approximately 1.5 Gbp. In plants, the family of pyrabactin resistance 1 (PYR1)/PYR1-like (PYL)/regulatory components of ABA receptors (RCAR) play a vital role in the initial step of ABA signaling, leading to abiotic stress resistance. Here 20 CqPYL genes were identified using the genome-search method. Based on the phylogenetic analysis, these CqPYL genes were divided into three classes or subfamilies. These genes have different structures and intron numbers, even within the same subfamily. Analysis of conserved motifs showed the presence of the PYR_PYL_RCAR motif domain in each PYL protein sequence. Furthermore, the tissue-specific expression of CqPYLs was analyzed through public available RNA-seq data. CqPYL4a/b and CqPYL8c/d showed higher expression levels in seedlings. Finally, 3D structures of the CqPYL proteins were predicted by homology modeling and analyzed through topology inspection to speculate on putative new ABA receptor features. This study provides a theoretical basis for further functional study of PYL genes for stress-resistance breeding of quinoa and other crops.

As a result of the analysis of scientific domestic developments, the authors formulated the concept of «rational use of agricultural land», and developed land use indicators. The approbation was carried out in the Novgorod and Khom districts of Novgorod region, which make a different contribution to the agricultural production of the region. The authors concluded that due to lack of incentives for agricultural production, areas that initially have the same opportunities and similar qualitative characteristics realize their natural resource potential based on the prevailing socio-economic conditions. In this regard, it is necessary to use various economic mechanisms aimed at involving unused agricultural land in economic circulation in order to achieve rational use of these areas.
DOCTRINAL PROBLEMS FORENSIC EXAMINATION IN THE INTEGRATIVE DOCTRINE OF EVIDENCE-BASED LAW
Authors: Tertyshnyk Volodymyr , Varava Volodymyr
Published: August 2022

The article reveals the problems of forensic examination in the integrative doc-
trine of evidentiary law, taking into account the provisions of the Constitution of
Ukraine, procedural legislation, the case-law of the European Court of Human
Rights, and judicial precedents of the Supreme Court of Ukraine.
In the context of the formation of its doctrinal principles and individual legal in-
stitutions, we propose to consolidate here the provisions of the following content:
“The evidence is the factual data obtained in accordance with the procedure pro-
vided by law that meet the requirements of belonging to the case, admissibility and
reliability”. “Factual data obtained during the conduct of expert studies, investigators
or other procedural or regulated by separate laws of research actions can be used
in legal evidence, provided that the source and method of their obtaining, the evi-
dence obtained, are not “fruits of a poisonous tree” are clarified and can be verified.
The peculiarities of the expert's conclusions and written conclusions of special-
ists are disclosed, and a simplified procedure for assigning examinations and the
formation of the results of expert research is proposed.
It is concluded that it is necessary to adopt a universal legislative act – the “Code
of Evidence”. It is proposed to include in its conceptual model the norms of the gen-
eral and special parts. In the general part, at the integrative level, intersectoral char-
acters should be set out, norms common for all forms of legal proceedings, which
will determine the concepts and types of evidence and the criteria for their admissi-
bility. In a special part, modern norms should be laid down – standards of evidentiary
law governing the receipt, research, verification, evaluation, and use of evidence,
the production of forensic examinations.
It is proposed to differentiate art and humanitarian examination, the need to ex-
pand the types of examinations and the formation of the subject and features of such
independent examinations as forensic and humanitarian, legal, stock market exam-
ination, environmental and land examination are being bypassed.
Key words: examinations, expert conclusions, evidence, evidentiary law.
DEVELOPMENT OF A PROFESSIONAL STANDARD “FORENSIC EXPERT” AS ONE OF THE AREAS FOR IMPROVING FORENSIC ACTIVITIES
Authors: Poltavskyi Andryi
Published: August 2022

The article is devoted to the problem of insufficient normative regulation of the
relevant education, skill level, training, competencies and competencies of forensic
experts. The current regulations are analyzed, in particular, the Law of Ukraine “On
Forensic Expertise”, approved classification characteristics for the profession “Fo-
rensic Expert”. The latter were approved in 2007 and have not changed to this day,
despite numerous changes in Ukrainian legislation.

From this point of view, publications were analyzed that analyze the regulation
of education and requirements for the profession of Australia, Canada, the USA,
Germany, Japan and other countries where professional standards (corporate, in-
dustry, regional, national and international) are developed, implemented, improved
in the field:

– work to form and maintain a high professional level of employees, which meets
the needs of production, determine the needs for workers and the level of their pro-
fessional training;
– education for the development of educational standards and vocational train-
ing programs, methods for assessing and attesting the results of vocational training,
effective and reasonable selection of personnel.

The use of professional standards, according to foreign politicians, practitioners,
experts and researchers, is the engine for the development and functioning of both
the labor and education sectors.
In connection with this, Ukraine did not stay aside either. Several normative acts
of Ukraine, in particular the Code of Labor Laws, the Laws of Ukraine “On Education”
and “On Vocational Education” were amended and supplemented, due to which the
term “professional standard” appeared in the legal field.
A comparative analysis of the information contained in the classification charac-
teristics for a profession and professional standards showed that the information in
the standard is the most voluminous and detailed. The main differences between the
characteristics and standards are that the latter are developed in accordance with
the national and sectoral qualification frameworks, which, in turn, comply with the
European qualification framework developed within the framework of the Bologna
process, to which Ukraine joined in 2005. There is no professional standard “Foren-
sic Expert” in the state, which makes it impossible to update the requirements for
education, training programs, specialty passports, etc.
There is no professional standard “Forensic Expert” in the state, which makes it

Authors: Foloni José Salvador Simonetto , Abati Julia , Henning Fernando Augusto
Published: August 2022

Spatial arrangement between plants and sowing time used are decisive practices for obtaining adequate agronomic performance in soybean crop. The aim of this work was to evaluate morphological attributes, yield components and grain yield of soybean cultivars installed with different row spacing and seeding densities, in early (10/04/2017) and conventional (11/08/2017) sowing dates in subtropical climate region in southern Brazil. The experimental design was in a 2×2×4 factorial arrangement: soybean cultivars BRS 433 RR (MG 5.8) and BRS 1003 IPRO (MG 6.3) installed with row spacing of 25 and 50 cm and seeding densities of 160,000; 240,000; 320,000; and 400,000 viable seeds ha-1. Morphological attributes and yield components are altered by spatial arrangement between plants and cultivar, with variable responses according to the sowing date. In the early sowing date, soybean has yield raise due to the increase in seeding density with different responses between cultivars. In the conventional sowing date, soybean installed with 25-cm row spacing has an increase in 1000-grains weight. In the conventional sowing date, there is an increase in soybean yield installed with 25-cm row spacing associated with a seeding density of 320,000 to 400,000 viable seeds ha-1.

Introduzir um instrumento lúdico diferente, como ferramenta ou recurso de consolidação de saberes de disciplinas, no caso deste estudo, para matemática e programação, que costumam apresentar muita reatividade, pode auxiliar na fixação destes novos saberes e reduzir a “aversão” no aprendizado das mesmas. Através de aplicações, ao longo de dois anos e meio anos, em uma escola pública, mediante análises quantitativas e qualitativas, observou-se que o jogo denominado Cubo de Rubik, pertencente a cosmovisão dos discentes, pode não só melhorar os seus desempenhos, mas também auxiliar na prática dos conceitos ensinados. Esse recurso permitiu transferir o cotidiano da vida do estudante para o mundo da sala de aula, construindo uma ponte de aprendizado mais agradável e lúdica das disciplinas consideradas difíceis. Verificou-se também que, trazendo para a sala de aula essa visão comum (de um jogo), segundo uma metodologia livre, o aprendizado transformou-se em uma experiência nova e mais fácil para adquirir saberes. Colaborou para essas melhorias, e no novo “como ver” dessas disciplinas, uma metodologia baseada no Gestaltismo, ou Psicologia da Forma.

Published: August 2022

Objective
. This paper is an initial work towards developing particle-mediated histotripsy (PMH) as a novel method of treating catheter-based medical device (CBMD) intraluminal biofilms.
Impact Statement
. CBMDs commonly become infected with bacterial biofilms leading to medical device failure, infection, and adverse patient outcomes.
Introduction
. Histotripsy is a noninvasive focused ultrasound ablation method that was recently proposed as a novel method to remove intraluminal biofilms. Here, we explore the potential of combining histotripsy with acoustically active particles to develop a PMH approach that can noninvasively remove biofilms without the need for high acoustic pressures or real-time image guidance for targeting.
Methods
. Histotripsy cavitation thresholds in catheters containing either gas-filled microbubbles (MBs) or fluid-filled nanocones (NCs) were determined. The ability of these particles to sustain cavitation over multiple ultrasound pulses was tested after a series of histotripsy exposures. Next, the ability of PMH to generate selective intraluminal cavitation without generating extraluminal cavitation was tested. Finally, the biofilm ablation and bactericidal capabilities of PMH were tested using both MBs and NCs.
Results
. PMH significantly reduced the histotripsy cavitation threshold, allowing for selective luminal cavitation for both MBs and NCs. Results further showed PMH successfully removed intraluminal biofilms in Tygon catheters. Finally, results from bactericidal experiments showed minimal reduction in bacteria viability.
Conclusion
. The results of this study demonstrate the potential for PMH to provide a new modality for removing bacterial biofilms from CBMDs and suggest that additional work is warranted to develop histotripsy and PMH for treatment of CBMD intraluminal biofilms.

Highlighted Virtues in Iniyavai Narpatu
Authors: N.R Shibaja
Published: August 2022

Virtue is living blamelessly in one's mind. Thiruvalluvar has said in the authority entitled Aran Emphasis that everything done without purity of heart is of an avaricious nature. The word Aram refers to ten things namely Dharma, Puniyam, Merit, Religion, Wisdom, Charity, Fasting, Cursing, Dharma Goddess, and Yaman. The term Aram is derived from the word Aru. Virtue is the elimination of evil, the removal of vice, the eradication of guilt, and freedom from worldly desires. Virtue is a measure of justice and it is a natural virtue that develops in society. If you want to achieve perfection of virtue, you need to be active in a state where the mind, language, and meaning are combined. In today's situation, we see the growing feeling of enmity among people on the basis of caste, religion, race, language, country, etc. It can be considered that the basic reason for the hatred of each other on the basis of religion and caste is flagging all over the world today. Therefore, love should be increased by eliminating enmity. Love is born in a heartless heart and respect is born in a heart without arrogance. The virtue that is necessary for today's practice is that people should protect all living beings as if they are their own life. justice literature is based on this unity. Therefore, this book is organized as a group for this concept. The author of Iniyavai Narpatu was Boothanchendanar. He was called Boothanchendanar, the son of a Madurai tamilaciriyar makanar. He points out that these are the good morals of the book.

Hospitality Characteristics of Tamil People
Authors: K.M Panbarasi
Published: August 2022

Hospitality was extolled as a domestic virtue of Tamils. Antiquity was a time when there were no restaurants. People traveling from one town to another cannot carry enough food for several days. They ate the food given to them in the towns they were going to. Thus, feeding a new guest was regarded as the highest virtue. The guests were welcomed and treated with gusto. Hospitality was maintained as the duty of the householder. The guest served as a gateway to resolve disputes between husband and wife. They fulfilled their duties to the guest with alacrity. Everyone from the king to the citizens feasted according to their status. Even though they were poor, they were hospitable. They have the habit of not eating alone when there is a guest even if they get nectar. Hospitality and cultural elements coexist with life. Hospitality and cultural elements coexist with life.

Esta investigación se realizó en la región hulera del Papaloapan, en el Estado de Oaxaca, México, con el objetivo de generar una ecuación para predecir la producción de látex del clon IAN-710 de Hevea brasiliensis Müll. Arg. Se utilizó información dasométrica de 1562 árboles provenientes de 82 sitios temporales de muestreo de plantaciones comerciales de este clon, de entre 7 y 42 años de edad. Las principales variables asociadas con la producción de látex fueron el diámetro normal (a 1.30 m), la altura total y la edad de los árboles. Se compararon tres modelos de los tipos: variable combinada generalizada de forma cuadrática, logarítmica generalizada, gamma incompleta de forma exponencial, con una o más de las variables anteriormente mencionadas. La ecuación que tuvo uno de los mejores ajustes (R2 = 0.8755) para la predicción de la producción de látex (P), fue el modelo de la gamma incompleta de forma exponencial (P=β0 dβ1 e-β2d) con base en el diámetro normal (d) y con una desviación estándar de 0.1239. La producción comercial de látex inicia con 1.561 kg/árbol x año, se incrementa hasta alcanzar un máximo de 2.446 kg/ árbol x año en árboles de 25 cm de diámetro; luego inicia su declinación gradual hasta 1.065 kg/ árbol x año en árboles con diámetro de 49 cm. La vida útil de la plantación es de 30 años de edad.

El alto consumo de maíz como alimento básico en México, hace deseable que se produzcan maíces más nutritivos, ya sea que tengan mayor cantidad o mayor calidad de proteína. Por esta razón el Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias (INIFAP), en colaboración con el Centro Internacional de Mejoramiento Maíz y Trigo (CIMMYT), han desarrollado híbridos y variedades de maíz con alta calidad de proteína, como son las variedades de maíz V-537C y V-538C, las cuales proporcionan un mejor balance de los aminoácidos escenciales lisina y triptofano, que ayudarían a fortalecer el nivel nutricional de los mexicanos.

This study analyzed the structural relationship between teachers' teaching methods and middle school students' self-concept, career maturity, and creative thinking ability, and verified the mediating effect of self-concept and career maturity on the relationship between teachers' teaching methods and creative thinking ability. For this purpose, data from the second year of middle school in the 4th year of 「Korean Educational Longitudinal Study 2013」 of the Korean Educational Development Institute was used. To verify the structural relationship between the variables, a total of 6,326 data were analyzed using the structural equation modeling, and the mediating effect was verified through bootstrapping. As a result of the study, the direct effect of the teacher's teaching method on self-concept and career maturity was statistically significant, but the direct effect of the teacher's teaching method on creative thinking ability was not statistically significant. On the other hand, the teacher's teaching method was found to have a statistically significant indirect effect on creative thinking ability through self-concept and career maturity. These results suggest that there is a limit to improving students' creative thinking ability only with the teacher's teaching method, and creative thinking ability can be improved through students' personal characteristics such as self-concept and career maturity. Therefore, in order to improve students' creative thinking ability, teachers' teaching methods need to be designed in consideration of students' self-concept and career maturity.

Islamic Thought in Africa: The Collected Works of Afa Ajura (1910-2004) and the Impact of Ajuraism on Northern Ghana (by Alhaji Yusuf Salihu Ajura, translated by Zakyi Ibrahim)

Since the formal end of colonial occupation of African countries by the imperial powers, the last few decades have witnessed ballooning interests in the study of Islam and Muslim societies in especially West Africa. This is partly complimented by the sudden religious transformations and radical shifts from syncretistic strands of Islam brought about by different Islamic reform projects. This factor has posed decisive survival threats to these synctretist groups as the edifices upon which they were initially constructed were being subjected into perpetual checks and cross-examinations. Consequently, the reform projects at times necessitated an internal reexamination within Islamic groups that were hitherto tainted and dominated by traditional practices and beliefs that seem to no longer appeal to scientific and inquisitive minds.

Objetivo: avaliar a geração e o gerenciamento de Resíduos de Serviços de Saúde (RSS) nos serviços inseridos na Atenção Básica à Saúde. Método: estudo descritivo e de abordagem quantitativa.  Esta pesquisa foi realizada com os responsáveis pelo gerenciamento de RSS de 27 estabelecimentos de saúde. Os dados foram coletados por meio de questionários autorrespondidos e pesagem dos RSS e foram analisados por meio da estatística descritiva. A pesquisa foi aprovada pelo Comitê de Ética em Pesquisa da UFSCar. Resultados: os 27 estabelecimentos de saúde geraram 719,665 kg de RSS, sendo 300,140 kg de RSS gerados pelas Equipes de Saúde da Família (EqSF) e 419,525 kg de RSS oriundos das Unidades Básicas de Saúde(UBS). Destaca-se que 66,6% (14) dos participantes de EqSF não souberam descrever como era realizada a segregação dos resíduos químicos; e, 50,0% (6) dos respondentes de UBS não souberam informar o tipo de disposição final oferecida aos RSS. Conclusão: a elevada geração de RSS e as lacunas apresentadas no gerenciamento podem ser minimizadas por meio da implementação de medidas que visem a capacitação dos responsáveis pelo manejo e trabalhadores dos serviços de saúde, além da implantação da coleta seletiva a fim de contribuir para um desenvolvimento sustentável.
