IntroduçãoA migrânea é uma doença caracterizada por cefaleia acompanhada de hipersensibilidade sensorial como fotofobia, fonofobia, osmofobia e alodinia. Objetivo: Investigar a associação entre a sensibilidade sensorial (alodinia, fonofobia, fotofobia e osmofobia) e outras variáveis clínicas relacionadas a migrânea.MétodosEstudo observacional composto por participantes com diagnóstico de migrânea com e sem aura de ambos os sexos, com idade entre 18 a 70 anos. Foram avaliados sexo, idade, índice de massa corpórea (lMC) e etnia. Foram obtidas informações sobre tipo de migrânea com ou sem aura; episódica ou crônica), idade de início da doença, frequência das crises, sintomas acompanhantes e desencadeantes de cefaleia. Os participantes responderam sobre a presença ou ausência de alodinia, fonofobia, fotofobia e osmofobia. Avaliouse também o grau de incapacidade da migrânea, por meio do questionário Migraine Disability Assessment (MIDAS). Os dados categóricos foram avaliados por teste de qui-quadrado ou Exato de Fisher. Dados contínuos foram avaliados pelo teste de Mann-Whitney. Foi considerada diferença estatística quando p<0,05ResultadosParticiparam do estudo 111 indivíduos com migrânea, destes 83,7% eram do sexo feminino, 36,9% apresentavam aura e 54,9% tinham a forma crônica da doença. Pacientes do sexo feminino tiveram mais frequentemente alodinia (OR 1,246; p=0,009), fonofobia (OR1,458; p=0,007) e osmofobia (OR 1,430; p<0,001). Pacientes com osmofobia tinham menor IMC comparado com os que não tinham essa condição (24Kg/m2 Vs 28 Kg/m2; p=0,046). Pacientes com alodinia tiveram chance 70% maior de terem migrânea com aura (OR 1,707; p=0,004) e maior quantidade de dias de cefaleia no último mês (10 dias Vs 5 dias; p=0,003) comparado com os que não tinham alodinia. Tinham maior pontuação no MIDAS aqueles indivíduos com alodinia (26 Vs 12; p=0,001) e fonofobia (20 Vs 14; p=0,018). O gatilho menstrual foi mais frequente entre mulheres com alodinia (OR 1,56; p= 0,041) e fotofobia (OR 1,211; p=0,012). Odor como gatilho foi mais comum em indivíduos com alodinia (OR 1,794; p= 0,003), fonofobia(OR 1,190; p=0,027) e osmofobia (OR 1,621; p=0,002), Gatilhos alimentares ocorreram mais frequentemente entre indivíduos com osmofobia (OR 1,438; p=0,019).ConclusãoO sexo feminino foi associado a maior chance de alodinia, fonofobia e osmofobia. A alodinia foi a manifestação de hipersensibilidade sensorial mais associada a gravidade e a gatilhos de migrânea.

Published: May 2021

IntroduçãoSegundo a Sociedade Brasileira de Disfunção Temporomandibular e Dor Orofacial, a dor orofacial (DOF) é uma condição dolorosa associada a tecidos moles e mineralizados da cavidade oral e da face. Entre crianças e adolescentes brasileiros, estima-se que haja uma prevalência de DOF de 25,2% que se relaciona com fatores como cefaleia e bruxismo, afetando demasiadamente a qualidade de vida dessa população. Dentre as opções de manejo da DOF, podem ser utilizados tratamentos invasivos ou não, ainda em discordância quanto à eficácia no público jovem. O objetivo deste estudo é buscar na literatura as opções terapêuticas atuais mais eficazes no manejo da dor orofacial de crianças e adolescentes com DTM.Material e MétodosTrata-se de uma revisão sistemática da literatura nos bancos de dados PubMed, Lilacs e MedLine, com os descritores: “(Temporomandibular Dysfunction OR DTM) AND Treatment” (n = 133). Foram selecionados os ensaios clínicos randomizados, relatos de caso e metanálises publicados nos últimos 10 anos, outros filtros utilizados foram: idade até 18 anos e texto completo (n = 31). Foram excluídos os estudos duplicados e aqueles que não se enquadravam nos objetivos. (n = 10).ResultadosAnquilose da Articulação Temporomandibular (ATM) é uma doença articular multifatorial que se refere à adesão óssea ou fibrosa dos componentes anatômicos da articulação, resultando na perda da função e em intensa e persistente DOF. Um relato de caso concluiu que, embora não haja consenso sobre a totalidade do tratamento cirúrgico no caso de ATM, indica-se começar o manejo terapêutico assim que for feito o diagnóstico com mobilização precoce, fisioterapia agressiva e acompanhamento clínico, tendo como objetivo restaurar a mobilidade mandibular e reduzir os episódios de dor. Ademais, um ensaio clínico randomizado constatou que a ATM éuma das desordens mais significativas do sistema estomatognático, pois causa dores associadas a graves limitações funcionais, como dificuldade de mastigação e problemas psicológicos e clínicos devido à má higiene bucal, sendo bastante significativos em crianças, pois o tratamento é ainda mais complexo devido ao fato da região condilar ser um local de crescimento ativo.ConclusãoA DTM associou-se muito a ATM e o seu tratamento precoce é fundamental para o manejo desse tipo de dor, principalmente quando envolve pacientes pediátricos.

Published: May 2021

In the absence of competition, allowing monopolists to discriminate on prices, sales volumes may increase by adopting lower prices for certain groups of consumers who would not otherwise have purchased. If price discrimination is not perfect, it increases consumer welfare - that is, if the price does not correspond to the evaluation of each product by the consumer, then discrimination allows for additional consumers to buy the product at a price, which is lower than the one they would have liked to pay for it. This often results in negative consequences for both consumers and sellers. In this case opportunities for international business are opening, as intervention from other markets can provide additional alternatives to buyers by reducing the negative impact of distorted competition for the balance of negotiating power of negotiators. But there is another problem here in assessing the concentration of market participants, their impact on price discrimination. The aim of the article is to analyze the existing theory and practice of negotiation strategy in a complex way, at different levels of competition, to reveal possibilities to develop and implement these strategies, taking into account the problems of price discrimination. The object of the article is the preparation of negotiation strategies at different levels of competition, taking into account the problems of price discrimination. The article deals with the problem - there are not enough tools in the negotiation theory to help develop negotiation strategies with different levels of competition and price discrimination problems. The paper analyzes the mathematical model of oligopoly. This model explores the feasibility and effectiveness of negotiation strategy preparation in the face of distorted market competition.

Authors: Bacaro Monariza
Published: May 2021

This study was conducted to determine the level of conceptual understanding and interest in Kinematics of 66 non-science curriculum high school students under a cooperative learning environment randomly assigned to the control (Traditional Method of Teaching) and experimental group (Cooperative Learning Approach). Student’s level of conceptual understanding was measured using a SOLO level-based Conceptual Understanding Test (CUT) and interest in kinematics was measured using a Student’s Interest in Kinematics Questionnaire. Before intervention, findings revealed that almost all of them could not answer questions that require one piece or more than one piece of given information, fact, or idea, obtained directly from the problem or ideas each used separately. They could not also answer two or more distinct steps, with no integration of the ideas or in doing algorithms with numbers using a set of useful information. Majority of them were on the prestructural and same level of conceptual understanding and has not really understand the concept asked, or with very little understanding, but they differ on interest level in learning kinematics in favour to the students assigned in the control group. After intervention, students exposed to Cooperative Learning Approach have significantly higher Pretest-Posttest mean gain score in the CUT than the students exposed to Traditional Learning Method. Almost half of the respondents were on the unistructural and less than one fourth were on the multistructural SOLO levels of conceptual understanding. However, students exposed to traditional method of teaching have interest that is significantly higher than the students exposed to cooperative learning approach. In terms of students performance students exposed to cooperative learning approach performed significantly higher than the students exposed to traditional teaching methods.

Authors: Osaretin Paul Otubu,
Published: May 2021

The study examined the impact of bank credits on the manufacturing sector in Nigeria from 1980 to 2015. The broad objective of the study is to examine the impact of bank credits on the manufacturing sector in Nigeria between 1980 and 2015. The econometrics methods of ordinary least squares, co-integration, error correction model and granger causality test were used as the main analytical tools. From the estimated error correction model, we found that bank credits to the manufacturing sector had a positive impact on the manufacturing sector output. Government expenditure, gross capital formation and tertiary school enrolment conforms to apriori expectation. A bank credit was found to be necessary for influencing or boosting manufacturing sector output. In addition, the granger causality result reveals that there is causal relationship between bank credits and manufacturing sector output in Nigeria. It is therefore recommended that the cost of borrowing should be reduced, and relevant authorities should maintain a sustained effort aimed at making sure that banks strictly comply with the credit concession granted to the manufacturing sector, and the government should provide social amenities and conducive environment for industrialization.
Has Demonetization Made Indians to Embrace Digital Technology in Banking?
Authors: Saji T.G
Published: May 2021

This research investigates the differences in the technology adoption behaviour of customers of Indian banks during the pre and post demonetization phase. The Survey results of 200 bank customers in India find that the Indians are still holding back from embracing the digital platforms to make payments. The study could not establish the constructive effects of demonetization in e-banking adoption behaviour, despite the significant growth in the use of small digital payment platforms like Paytm. However, the usage of Point of Sale (POS) machines for transacting payments has increased tremendously. The research finds drastic reductions in the use of other e-payment modes during and after demonetization. In that sense, the study concludes that the demonetization negatively affects the technology banking adoption behaviour of customers of Indian banks.

Published: May 2021

Exposure to fumes when grilling meat predisposes human to a significant level of cancer-causing compounds called PAHs (Polycyclic Aromatic Hydrocarbons. The DNA damaging capacity of PAHs can be rapidly and inexpensively evaluated by measuring and counting the micronuclei in various cells. In this study, the frequency of micronucleation (MN) in exfoliated buccal epithelial cells of thirty (N=30) barbecue grillers (exposed group) in Marawi City was compared with thirty (N=30) office workers and students of Mindanao State University (control). A total of 1000 buccal epithelial cells per individual were scored for MN frequency. Results revealed a significant increase (p<0.05) in the MN frequency of barbecue grillers (18.97±3.77) compared with the control (12.6±3.58). In addition, possible effect of the established confounders which include smoking, drinking habits, age, gender and number of years of exposure to PAHs on the frequency of micronucleation was further analysed. Confounding factors that could have caused higher MN frequency in the exposed group are age (ρ=0.000) and length of exposure to grilling fumes (P=0.002). The current study confirms that chronic exposure to grilling fumes increases micronucleation, hence the necessity of biological monitoring and appropriate health interventions.

Authors: P. Villaver Jeffrey
Published: May 2021

There is a growing popularity of organic farming in the modern era because of its potential contributions in sustaining crop production without impairing the natural condition of the environment. In this study, the physiological parameters of sweet corn applied with rates of indigenous microorganisms (IMO) 7 such as: (120 kg N - 90 kg P2O5 - 60 kg K2O, IMO 7 at 7.5 t ha-1, 15 t ha-1, and 22.5 t ha-1) and biofertilizers - fish amino acid (FAA), fermented plant juice (FPJ), and fermented seaweed (FS) were evaluated at different crop stages at 45, 55, 65, and 75 days after planting. The study was conducted in a 4 x 4 factorial in Randomized Complete Block Design (RCBD) with three replicates. Rates of IMO 7 significantly influenced on the crop growth rate (CGR) at 55-65 days after planting (DAP), and carbon productivity (CP) while biofertilizers influenced on weight per ear, the number of kernels per ear, ear yield, and leaf area ratio (LAR) at 65 DAP. Synthetic fertilizers (120 kg N, 90 kg P2O5, 60 kg K2O) and IMO 7 at 22.5 t ha-1 gave the highest carbon productivity at harvest of 10.58 t ha-1 and 10.38 t ha-1, respectively. Fermented seaweed gave the highest ear yield, weight per ear, and the number of kernels per ear. IMO 7 at the rate of 22.5 t ha-1 gave the highest CGR at 19.5 mg g-1 day-1 or 25.64% higher than those plants treated with the minimum rate of 7.5 t ha-1. The results of the study provide information on the potentials of using IMO 7 in combination with fermented seaweed as organic fertilizers for sustainable sweet corn production.

Over the past few years, activated carbon (AC) has attained significant attention as an efficient adsorbent for heavy metal (lead, cadmium, chromium etc.) removal. In Bangladesh, bagasse and jute fibre are the two most potential raw materials for producing activated carbon due to their high availability and low cost. The activated carbon was produced by thermal treatment method. The produced AC were characterized using FTIR, XRD, SEM etc. Batch experiments under agitation was also carried out for adsorption of heavy metals and then characterized using AAS (Atomic Adsorption Spectroscopy). Adsorption with commercially available activated carbon was also done to use as standard. Among all ACs produced in this study, the highest percentage removal of heavy metals which were Cr3+ and Cd2+ was at 57.06% and 43.01% respectively for J-400 ( AC produced from jute fibre at 4000C). This obtained value was 16.6% and 12.9% higher in comparison to Commercially available Activated carbon for Cr3+ and Cd2+ respectively.

Published: May 2021

This study investigated the effects of video clips enrichment on the academic performance of Grade 8 learners in Earth and Space Science. This was conducted in MSU-ILS, MSU Campus, Marawi City, during the school year 2018-2019. The study employed the quasi-experimental non-equivalence pretest-posttest research design to test the effects of the video clips enrichment on the academic performance of Grade Eight learners. The academic performance of the two groups was assessed using the research-made 30-item multiple-choice test which has a reliability coefficient of 0.74, indicating that it was reliable and dependable to assess the academic performance of the learners. The data were treated with mean, standard deviation, and ANCOVA (Analysis of Covariance) at 0.05 level of significance. Moreover, the experiences of the learners in learning Earth and Space Science with video clips enrichment using their entries from the journal notebook and scheduled interview was administered after the conduct of the lesson and the post test. Results revealed that the learners taught with video clips enrichment in Earth and Space Science had a “very satisfactory” academic performance. This means that the learners at this level have developed the basic knowledge, skills and main understandings and can transfer them separately through genuine performance tasks. There is also a significant difference between the mean gain scores of the academic performance of Grade 8 learners taught with video clips enrichment and taught with K to 12 learning modules after the intervention, hence, the experimental group achieved significant growth in conceptual understanding which could be attributed to the use of video clips. The experimental group have gained positive experiences as it made them excited, attentive, and participative in class which could have resulted to their better academic performance in the subject. Therefore, the use of video clips in science lessons could enhance the academic performance of the learners.
Oil Revenue and Economic Growth; an Empirical Evidence from Nigeria
Authors: Brown Ewubare Dennis , Nnamaka Uzoma Chidoka
Published: May 2021

The study examined the effects of oil revenue on economic growth in Nigeria between 1980 and 2017. Time series data were sourced from secondary sources on Gross Domestic Product, Oil Revenue, Oil Rent and Domestic Price of Petrol. The analysis started by analyzing the descriptive statistics of the series and proceeded to examination of the stochastic characteristics of each time series by testing their stationary using Augmented Dickey-Fuller test. The ARDL model was used to estimate the coefficients of the parameters for both the short-run and the long-run. The F-statistics obtained from the bounds co-integration test shows a stable long run relationship between the variables. Findings from the study showed that in the long run, oil revenue and oil rent impacted on GDP positively although not significantly. In the short run however, both variables retarded economic growth in Nigeria. This goes a long way to show that the enormous windfall from crude oil in the nation has been mismanaged. The domestic price of petrol impacted positively on economic growth both in the long run and short run. The study therefore recommends a judicious use of the revenue generated from the oil sector to provide long term sustainable economic growth. In addition, due to the volatility and uncertainty in the oil sector in Nigeria, government should embark on a realistic diversification plan to alternative sectors of the economy to enhance the productive base of the nation seeing that crude oil is an exhaustible asset.

Employee turnover is a very critical issue for both employees and the organization they work for. All employers prefer to keep their turnover ratio as low as possible because it is not cost effective when an employee leaves the organization and the company needs to go through the recruitment process all over again to replace that one employee. It is always more expensive for any organization to hire new employees as it requires use of additional financial resources and time. Therefore managers must try to minimize employee’s turnover at all costs and find out the causes behind the turnover ratio so as to minimize the reasons for leaving. Some companies perform exit interviews to find out the reasons for turnovers and they try to resolve those issues. Turnover also makes an impact in employees’ productivity, moral, corporate culture and employers’ reputation. To keep productivity and moral high organizations’ needs to keep the turnover low and in addition it spreads good reputation about the company throughout the industry. Job satisfaction of employees can definitely reduce turnover and employers can play a major role in this process. Like other countries Bangladesh also has various factors that affect the cause of employee turnover. As our nation moves into a lower middle income country from its previous low income status, it will need to ensure that it has a healthy workforce with a positive work life balance. This in turn will keep the turnover ratio down to a minimum. As Bangladesh is still in its developing stages, skilled and competent man power is very limited. Therefore it will be very critical for Bangladesh to manage its employee turnover ratio for the private, government and non-government sectors.

This paper empirically investigated the impact of value added tax (VAT) on economic growth in Nigeria from 1994–2018. This was done against the background that VAT as an indirect tax was introduced by the Federal Government of Nigeria in 1993 to replace sales tax with the sole aim of increasing the revenue base of government and make funds available for developmental purposes. The aim of the study is to examine the effect of value added tax on economic growth in Nigeria and determine the impact of other tax revenues particularly, custom and excise duties on economic growth in Nigeria. Thus, secondary data on GDP, VAT revenues, custom and excise duties were sourced from CBN statistical bulletin. Also, ARDL technique was used to analyze data. The variables were subjected to ADF unit root test prior the ARDL and found to be stationary. The ARDL co-integration test showed that there is a long run association amongst the variables. The ARDL short run result showed that the value of VAT has a positive relationship with economic growth in Nigeria. Also, custom and excise duties revenue positively impacted on economic growth in Nigeria. Hence, it was concluded that Value Added Tax (VAT) as an indirect tax system in Nigeria has direct relationship with economic growth in Nigeria since its inception in 1994. It has contributed to the total revenue of the nation as a result of reduction in tax evasion. Based on the findings, the paper recommended that government should put in place adequate measure to ensure that revenue generated from VAT is effectively utilized to develop and grow the economy in order to better the lives of the citizenry.

Published: May 2021

This paper collates seagrass studies from 2008- 2017. The focus of review is on the studies conducted in Philippines and in some areas of world in relation to this dynamic and most productive marine ecosystem the seagrass meadows. The review reveals that there is an abundance in diversity, distribution and cover of seagrass in different parts of the country, wherein articles written in other part of the world provides data and information on physical, biological and economic importance of Seagrass in the human lives. The cause of its destruction was found out to be mostly anthropogenic activities. Limitations on the conducted studies in the Philippines was shown as reflected in the collected studies that are generally done along the coastal areas in the Visayas and Mindanao regions. Which practically shows an opportunity to explore different places in Luzon for an assessment of Seagrass for its ecosystem resiliency, stability, management and sustainability. Foreign studies included in the review reflects studies on assessment of biophysical characteristics of the seagrasses with the use of modern technologies like remote sensing and management practices that illustrates market value of ecosystem services of seagrass meadows on its application for some small-scale fisheries. Knowledge gap on socio-ecological importance of seagrasses, economic valuation of this marine habitat ecosystem services and wake up call for policy maker to consider seagrasses in their proposal for management shift of this ecologically significant habitat are topics needing further investigations.

Corn, also known as maize, is one of the most important agricultural products produced by countries worldwide. Production of this crop is highly affected by climate change, especially if the water demand is not reach. With this, a rainfall-based index for crop insurance is an instrument to help farmers lower their risks in planting. The main objective of this study was to develop a rainfall-based index for corn crop insurance. Specifically, this study identified the threshold values for the index and estimated the probability of corn crop failure in the province of Isabela, Philippines. This study utilized Kolmogorov-Smirnov Test, Chi-Square Goodness of Fit Test, and Anderson-Darling Goodness of Fit Test to determine the probability distribution that best fits the data through Easyfit software and StatAssist, a built-in software in Easyfit to evaluate the probability of corn crop failure. The probability of crop failure for each stage of corn growth was obtained and based from the results, low-risk planting periods were found be: May to November for early crop growth stage, April and June to September for rapid crop growth stage, May to August for reproductive stage, and April to July for maturity stage. High-risk planting periods were found to be: January to March for early crop growth stage, January to March, May, November and December for rapid crop growth stage, January, February and October to December for the reproductive stage, and January, September to December for maturity stage.

The decline of fish production is one of the environmental issues in the province of Palawan, in which many households are highly dependent on fishing. This phenomenon may lead to a decline in household income or mass shifting of livelihood to other forms of livelihood like tourism-related activities. This study was conducted to determine the perceived ecological impacts of fishing livelihood and tourism-related activities to marine habitats which include seagrass, mangroves and coral reefs in Poblacion and Port Barton, San Vicente, Palawan. The perceived ecological impacts of fishing livelihood and tourism-related activities were determined using household interviews and key informant interviews through a face-to-face interview. Results show that the ecological impacts of fishing and tourism-related activities are degradation of coral reef, seagrass and mangroves and improvement through policies.
