Authors: Mora Rodríguez Damariz , Tapia Bolaños Paulina , García Zambrano Ximena 
Published: April 2021

El sistema de costos por órdenes de producción, busca tecnificar el cálculo de los costos incurridos en la elaboración de escaleras de aluminio de una empresa perteneciente a la industria manufacturera ecuatoriana. A través de esto, se logrará obtener costos más exactos, que permitan determinar precios que garanticen un margen de utilidad adecuado; para la sostenibilidad de la empresa en el mercado. En la determinación de costos se debe considerar todos los elementos relacionados con este concepto; para lo cual, el diseño de un sistema de costos por órdenes de producción representa una vía favorable, siendo este el modelo aplicado para estructurar un sistema de costos en la empresa en estudio. Como metodología para el desarrollo de la investigación se empleó el enfoque mixto y diseño no experimental con un tipo de investigación descriptiva. Por otra parte, para determinar la incidencia de dichos costos en la determinación de precios, se aplicó el modelo del costo total; ya que, este toma en cuenta los costos de producción y los costos del periodo en los cuales se ha incurrido. Se obtuvo como resultado un costo subvalorado de las escaleras, lo que conllevó a una reducción de la utilidad de aproximadamente un 70%; por lo cual, se evidencia que los costos no eran establecidos de forma idónea.

Authors: Humphrey Offodile , Ogu Charles 
Published: April 2021

Purpose: 12 week- brisk walking exercise intervention at 50%-70% intensity was carried out in the study to examine the mean reduction on systolic and diastolic blood pressures of middle-aged mild-hypertensive population in Asaba, Nigeria.
Methodology: The study comprised of 42 male and female middle-aged (36-45years) individuals who recorded mild-hypertension. A control group-pre-test and post-test experimental design was used to randomly assign the individuals into treatment and control groups. Whereas, arithmetic mean and standard deviation were used to analyze the data according to the difference in mean scores.
Conclusion: In conclusion, 12-week brisk walking intervention showed a mean reduction on systolic blood pressure (SBP) and diastolic blood pressure (DBP) of middle-aged mild-hypertensive population. Precisely, the experiment indicated that those who did not partake in the exercise intervention (control group) showed an increase on SBP and a decrease on DBP and thereby indicating a relatively higher mean reduction of 12-week brisk-walking exercise on SBP of middle-aged mild-hypertensive population.
Recommendations: The study recommended that 50% -70% intensity of 12-week brisk-walking exercise may likely present a therapeutic intervention for people with mild-hypertension.

Eggs are one of the animal products that come from poultry and have been known as a source of high quality protein food. From the many eggs we know, one of the eggs that comes from poultry is quail eggs. Quail eggs have complete nutritional content ranging from protein, fat, vitamins and minerals. Even so, quail eggs are also animal food that is easily decreased in quality due to bacterial contamination, contamination of quail eggs by bacteria can affect the quality of the contents of the eggs, bacteria that cause egg contamination, one of which is Escherichia coli.
This study aims to determine the presence of Escherichia coli bacteria in quail eggs that are sold in the central market of Gorontalo city.
The research method used is descriptive research type with a quantitative research approach, cross sectional research design, a sampling place for the central market of Gorontalo City and a place for researching samples of the Microbiology Laboratory of Gorontalo State University, the number of samples used was 30 samples of quail eggs. Quail eggs were positive for Escherichia coli bacteria with a percentage of 6.7%, and negative egg yields from Escherichia coli bacteria were 28 or 93.3%. It can be concluded that from 30 samples of quail eggs there were 2 quail eggs that were positive for Escherichia coli bacteria, the bacteria contamination factor in eggs was influenced by external factors. Environmental sanitation conditions were not clean, egg storage temperature, egg storage time,

Published: April 2021

This study aims to examine the determinants of workers’ remittances and their impact on economic growth in Yemen. Autoregressive Distributed Lag (ARDL) bounds test to co-integration and error correction model (ECM) were applied on data covering the period from 1990 to 2014. According to the model of remittances determinants, workers’ remittances in Yemen respond to the macroeconomic conditions of both the home and host countries. It is found that, in the long-run, migrant stock and income level at the host countries are positively and strongly influence remittances level, with a feeble impact of domestic inflation rates. The effect of the home country’s income seems to be positive but insignificant in explaining the behavior of remittances level. The model of economic growth suggests that, in the long-run, the impact of workers’ remittances appears to be positive and moderate with positive and stronger influences observed for financial development and official development assistance. Accordingly, it is recommended that a lesser weight should be given to remittances in the strategic planning process, taking into consideration the increasing potentials of the conditions in the neighboring host countries to be changed. In addition, using remittances as a means of economic growth can be enhanced by encouraging migrants to direct their savings towards productive investment activities, and via formal channels.

Published: April 2021

Abstract
Importance: Instrumental activities of daily living (IADLs) are important for independence, safety, and productivity, and people with Parkinson’s disease (PD) can experience IADL limitations. Occupational therapy practitioners should address IADLs with their clients with PD.
Objective: To systematically review the evidence for the effectiveness of occupational therapy interventions to improve or maintain IADL function in adults with PD.
Data Sources: MEDLINE, CINAHL, PsycINFO, OTseeker, and Cochrane databases from January 2011 to December 2018.
Study Selection and Data Collection: Primary inclusion criteria were peer-reviewed journal articles describing Level 1–3 studies that tested the effect of an intervention within the scope of occupational therapy on an IADL outcome in people with PD. Three reviewers assessed records for inclusion, quality, and validity following Cochrane Collaboration and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.
Findings: Twenty-two studies met the inclusion criteria and were categorized into four themes on the basis of primary focus or type of intervention: physical activity, specific IADL-focused, cognitive rehabilitation, and individualized occupational therapy interventions. There were 9 Level 1b, 9 Level 2b, and 4 Level 3b studies. Strong strength of evidence was found for the beneficial effect of occupational therapy–related interventions for physical activity levels and handwriting, moderate strength of evidence for IADL participation and medication adherence, and low strength of evidence for cognitive rehabilitation.
Conclusions and Relevance: Occupational therapy interventions can improve health management and maintenance (i.e., physical activity levels, medication management), handwriting, and IADL participation for people with PD. Further research is needed on cognitive rehabilitation. This review is limited by the small number of studies that specifically addressed IADL function in treatment and as an outcome.
What This Article Adds: Occupational therapy intervention can be effective in improving or maintaining IADL performance and participation in people with PD. Occupational therapy practitioners can address IADL function through physical activity interventions, interventions targeting handwriting and medication adherence, and individualized occupational therapy interventions.

Published: April 2021

O uso de imagens de satélite como ferramenta de monitoramento ambiental tem grande aplicabilidade em diversas áreas. Contudo, uma área pouca explorada é o monitoramento de recursos hídricos devido à falta de parâmetros que correlacionem a qualidade da água e as imagens. Esta pesquisa avalia o uso de imagens LandSat 8 e Sentinel 2 no monitoramento de reservatórios de abastecimento do Complexo Capim Branco em Uberlândia, MG. Foram analisadas as alterações da resposta espectral em relação a turbidez e sólidos totais. As imagens do sensor MSI do satélite Sentinel 2 apresentaram precisão espectrais compatíveis com o LandSat 8, mas ao analisar todas as bandas do espectro visível e infravermelho próximo, foi verificado que as imagens LandSat 8 têm maior capacidade de diferenciação de elementos suspensos na água. Os resultados permitiram estabelecer uma equação de correlação entre a turbidez com as bandas das imagens para cada reservatório.

IntroductionGastric cancer is a frequently detected malignancy and its incidence has increased over the past decades in East Asia. The present study investigated the effect of 5,7,2, 5 -tetrahydroxy-8,6 –dimethoxyflavone (THDMF) on gastric cancer cells and explored the underlying mechanism.Material and methodsMTT colorimetric assay was used for measurement of MKN28, MKN45and GES 1cell proliferation and flow cytometry for detection of apoptosis. Transwell and wound healing assays were used to observe the invasion and migration abilities of MKN28 cells. The expression of p21, MMP2/-9, PI3K and c Myc proteins was detected by western blotting.ResultsThe THDMF treatment significantly (P<0.05) reduced MKN28 and MKN45 cell proliferation without changing GES 1 cell viability. A significant increase in apoptotic cell population on treatment with THDMF was observed. Treatment of MKN28 cells with THDMF increased percentage of cells in G1 phase. Exposure of MKN28 cells to THDMF caused a marked decrease in invasion and migration potential. The expression of miR 145 was markedly increased in MKN28 cells on treatment with THDMF. In MKN28 cells expression of c Myc, PI3K, p AKT, MMP-2 and MMP-9 was suppressed markedly. The expression of p21 protein was markedly promoted on exposure to THDMF.ConclusionsIn summary, THDMF exhibits anti-cancer effect on gastric cancer cells in vitro by activation of cell apoptosis and arrest of cell cycle. In addition, THDMF promoted miR 145 expression and down-regulation of PI3K/AKT signaling pathway in MKN28 cells. Therefore, THDMF may be utilized as a potential novel therapeutic agent for the treatment of gastric cancer.
Student Retention in secondary schools of Seventh-day Adventist Church in East Kenya Union Conference
Authors: Kamundi Shadrack 
Published: April 2021

The study assessed students’ retention in secondary schools of the SDA Church in EKUC. It employed a concurrent mixed methods research design and adopted an exploratory approach using a descriptive survey. The subjects of the study included students, principals, the Conferences/Field Education Directors and the Board of Management (BoM) chairpersons. Based on expectancy theory of motivation, the study adopted the concurrent mixed methods research design. The target population was the twenty Seventh-day Adventist Church maintained Secondary Schools in EKUC. The unit of analysis was eleven secondary school principals, five education directors and, eleven chairpersons of the school boards of management (BOM) and 335 students. Cluster sampling technique was used to get the samples. The target population was divided into five clusters (principals, students, education directors and, board chairpersons). Samples were obtained from each of these clusters. The instruments used for data collection were questionnaires for students. Interview schedules were organized for education directors, the school BoM chairpersons and the principals for triangulation. Observation schedule was also organized. This targeted the school infrastructure and generally all what goes on in the school. The school learning facilities and the behavior of teachers in school was also captured here. The other instrument used was the tool for document analysis to collect data for 8 years. Students (335) were required to fill the provided questionnaire, but the eleven principals, five education directions and eleven BoM chairpersons were subjected to interviews. Documentary analysis method was used to get information on KCSE performance for the same period of eight years. The data collected was analyzed using descriptive statistics such as frequencies, percentages, means and standard deviations. Documentary analysis was done on records about teacher retention. Content analysis was done on responses from interviews and in open-ended questions. The findings show that there were high numbers of students in Form 2 and 3 who dropped within the year and those who joined. Students were being replaced as they dropped out in some of the years. All in all, there were high annual turnover rates. This could affect the learning processes as well as students’ academic performance. The study recommends the need for schools to put in place strategies for ensuring that students learning facilities were available. Students should also be motivated to remain in school. Bursaries and sponsorships for students from poor backgrounds should be availed. Spiritual guidance, work programs and flexible fees payment mechanisms should also be instituted so as to support children from poor background to remain in school.
The impact of sea waves on turbulent heat fluxes in the Barents Sea according to numerical modeling
Authors: Myslenkov Stanislav , Shestakova Anna , Chechin Dmitry 
Published: April 2021

Abstract. This paper investigates the impact of sea waves on turbulent heat fluxes in the Barents Sea. The Coupled Ocean–Atmosphere Response Experiment (COARE) algorithm, meteorological data from reanalysis and wave data from the WAVEWATCH III wave model results were used. The turbulent heat fluxes were calculated using the modified Charnock parameterization for the roughness length and several parameterizations that explicitly account for the sea wave parameters. A catalog of storm wave events and a catalog of extreme cold-air outbreaks over the Barents Sea were created and used to calculate heat fluxes during extreme events. The important role of cold-air outbreaks in the energy exchange between the Barents Sea and the atmosphere is demonstrated. A high correlation was found between the number of cold-air outbreak days and turbulent fluxes of sensible and latent heat, as well as with the net flux of longwave radiation averaged over the ice-free surface of the Barents Sea during a cold season. The differences in the long-term mean values of heat fluxes calculated using different parameterizations for the roughness length are small and are on average 1 %–3 % of the flux magnitude. The parameterizations of Taylor and Yelland (2001) and Oost et al. (2002) lead to an increase in the magnitude of the fluxes on average, and the parameterization of Drennan et al. (2003) leads to a decrease in the magnitude of the fluxes over the entire sea compared with the Charnock parameterization. The magnitude of heat fluxes and their differences during the storm wave events exceed the mean values by a factor of 2. However, the effect of explicitly accounting for the wave parameters is, on average, small and multidirectional, depending on the parameterization used for the roughness length. With respect to the climatic aspect, it can be argued that explicitly accounting for sea waves in the calculations of heat fluxes can be neglected. However, during the simultaneously observed storm wave events and cold-air outbreaks, the sensitivity of the calculated values of fluxes to the parameterizations used increases along with the turbulent heat transfer increase. In some extreme cases, during storms and cold-air outbreaks, the difference exceeds 700 W m−2.
Integrated water vapour content retrievals from ship-borne GNSS receivers during EUREC4A

Published: April 2021

Abstract. In the framework of the EUREC4A (Elucidating the role of clouds–circulation coupling in climate) campaign that took place in January and February 2020, integrated water vapour (IWV) contents were retrieved over the open tropical Atlantic Ocean using Global Navigation Satellite System (GNSS) data acquired from three research vessels (R/Vs): R/V Atalante, R/V Maria S. Merian and R/V Meteor. This paper describes the GNSS processing method and compares the GNSS IWV retrievals with IWV estimates from the European Centre for Medium-range Weather Forecasts (ECMWF) fifth reanalysis (ERA5), from the Moderate Resolution Imaging Spectroradiometer (MODIS) infrared products and from terrestrial GNSS stations located along the tracks of the ships. The ship-borne GNSS IWV retrievals from R/V Atalante and R/V Meteor compare well with ERA5, with small biases (−1.62 kg m−2 for R/V Atalante and +0.65 kg m−2 for R/V Meteor) and a root mean square (rms) difference of about 2.3 kg m−2. The results for the R/V Maria S. Merian are found to be of poorer quality, with an rms difference of 6 kg m−2, which is very likely due to the location of the GNSS antenna on this R/V prone to multipath effects. The comparisons with ground-based GNSS data confirm these results. The comparisons of all three R/V IWV retrievals with MODIS infrared products show large rms differences of 5–7 kg m−2, reflecting the enhanced uncertainties in these satellite products in the tropics. These ship-borne IWV retrievals are intended to be used for the description and understanding of meteorological phenomena that occurred during the campaign, east of Barbados, Guyana and northern Brazil. Both the raw GNSS measurements and the IWV estimates are available through the AERIS data centre (https://en.aeris-data.fr/, last access: 20 September 2020).
