The need for widespread introduction of renewable energy sources requires giving attention to all his components as follows energetic, environmental, operational, economic and social efficiency. Today, a more promising way is the use of solar energy to obtain liquid and gaseous fuels in detail to produce liquid and gaseous fuels [1, 10, 11]. In contrast to wind turbines and photovoltaic power stations, the cost of introducing biogas plants pays back from 5 to 26 months, that depend on the volume of reactors [12]. With the introduction of biogas technologies, the following goals can be achieved: cheap production of heat and electric energy (individual and state level), increasing crop yields through the using of effluent (individual and state level); improving the quality of agricultural products - the production of ecologically safe products; improving the social conditions of the rural population by creating a closed energy-saving production (individual and state level); preservation of forest plantations and reduction of soil erosion (mainly at the state level); savings due to lower energy costs and fertilizers (state level); reduction of internal migration from rural areas (state level).

The outbreak of the novel (SARS-CoV-2), known as COVID-19, has sparked global severe physical and mental health concerns in many spheres. Part of the identified mental health factors affecting people's psychosocial well-being is an increased level of health worries due to perception of vulnerability, which has been raised by excessive exposure to news, information on rising cases, mortality, and many others. This study focuses on the predictive influence of perceived vulnerability to COVID-19 infection among Nigeria residents during the COVID-19 outbreak. A total of 355 Nigerians, 175 (49.3%) males, 180 (50.7%) females aged between 18 years and 42 years (M = 27.24, SD =7.05) participated in the study through an online snowball method. Data was collected using the Perceived Vulnerability to Disease Questionnaire (PVDQ) and Mental Health Continuum Scale- Short Form (MHC-SF). Analysis of results reveals a high prevalence of low psychosocial well-being. That perceived vulnerability to COVID-19 infection significantly predicts psychosocial wellbeing (F (1,353) = 71.8, adj. R2 =.165, p <.01) among respondents. No significant sex influence was observed on psychosocial well-being; educational qualifications and marital status were found to influence the psychosocial well-being of Nigerian during COVID-19 Pandemic significantly. The authors conclude that perceived vulnerability to COVID-19 infection predicts the psychosocial well-being of Nigeria residents during the COVID-19 Pandemic outbreak.

Published: November 2020

Cardiovascular disease patients frequently suffer from the incidence of renal dysfunctions, the prevalence of the correlation, however, remains ambiguous. This study aims to see how CVD and renal function are related to the subjected group of patients suffer from symptoms of CVD. The method recruited for this objective was using of serum lipid profile test as a marker for evaluating the CVD and making correlations to the blood urea, serum uric acid, and serum creatinine levels as markers for assessing renal function on 159 individuals with CVD symptoms in Erbil city. Two statistical analysis methods (The linear regression and Pearson’s correlation) were employed for determining the existence from a lack of relationship between them. The results showed a statistically significant correlation p<0.05 by both methods between the renal function markers and TC. The UA was correlated to TG, LDL-C, and VLDL-C p<0.05 by regression analysis. The SCr was correlated to TG and LDL-C p<0.05 by both methods, and to VLDL by regression analysis. According to the outcome of the current study both lipid profile and renal function markers are correlated in mostly a statistically significant manner. Yet, the results are not conclusive, further studies are needed in this area for indemnify the irrefutable evidence concerning this relation.

Desperdicio de alimentos y tiempo disponible para trabajo doméstico. ¿Están correlacionados? Estudio exploratorio en un contexto urbano
Authors: Hernández-Rodríguez Clemente , Llamas-Rodríguez Francisco Javier
Published: November 2020

Objetivo: bajo la perspectiva de la economía circular, la presente investigación aborda una posible causa de la pérdida y desperdicio de alimentos que no ha sido analizada, esto es la falta de tiempo disponible de las familias para realizar trabajo doméstico. Metodología: en este estudio exploratorio se eligió un enfoque cualitativo descriptivo, con el objetivo de analizar la correlación entre la disponibilidad de tiempo para realizar trabajo doméstico en los hogares y el desperdicio de alimentos en los mismos. Para la recopilación de datos se realizó una encuesta a una muestra de hogares de una colonia de clase media en Guadalajara, Jalisco, México. Posteriormente, se llevó a cabo un análisis descriptivo y correlacional de las respuestas obtenidas. Resultados: se descubrió que hay ciertas actividades que implican un gasto de tiempo, que tienen que ver directamente con el trabajo doméstico –como revisar la despensa, hacer un inventario de los alimentos, escribir una lista de mandados, entre otras– que sí posee una relación con la cantidad de alimentos que se desperdician. Estas pequeñas actividades, con el tiempo, se convierten en hábitos de consumo inteligente. Limitaciones: se necesita una investigación confirmatoria adicional. Conclusiones: en conclusión, sobre la base de los datos obtenidos a través de la encuesta, es posible identificar dicha correlación positiva en este caso.

Metodología: se utilizaron datos del producto interno bruto (PIB) y de las exportaciones e importaciones, así como de los Censos Económicos para observar el comportamiento general de la industria y de las ramas más importantes a partir de cuatro variables: unidades económicas, personal ocupado, remuneraciones al personal ocupado y valor agregado censal bruto. Resultados: en términos de la distribución geográfica se observaron distintos patrones según las ramas alimentarias, sobre todo en la producción de lácteos, bebidas y otras industrias alimentarias, estas últimas aumentaron su importancia en algunas entidades del norte del país y mantuvieron su presencia en entidades del centro y occidente de México. Limitaciones: la investigación se sustenta en información secundaria con datos sectoriales y censales, los cuales permiten el cálculo de indicadores globales y el coeficiente de localización. Conclusiones: la industria alimentaria es afín al comportamiento de la economía mexicana y esta a su vez a sus vínculos con la economía norteamericana. La distribución de estas ramas en el país muestra su expansión en todo el país, aunque la producción se encuentre concentrada en estados del norte y centro del país. Esto ha llevado a la alta concentración del mercado de alimentos procesados.

Pūpūkahi i Holomua: A Story of Hawaiian Education and a Theory of Change
Authors: Kukahiko Keali‘i
Published: November 2020

The Hawaiian kingdom, prior to the illegal overthrow of its monarchy (1893) and the subsequent English-only Law (1896), had boasted a 91-95% literacy rate. Within that learning environment learners had a clear sense of purpose because Hawaiians had a firm grasp of who they were, where they were, and what they had to contribute. Since the English-only Law and US annexation of Hawai‘i (1898), however, the settler colonialschool system has maintained levels of cultural dissonance that have manifested as inequitable student outcomes for Native Hawaiians and Pacific Islanders (NHPI) across multiple academic and disciplinary student indicators (i.e., proficiency, suspension rates, etc). While western law and US compulsory education severed traditional sources of knowledge production that had provided a sustainable model of a‘o (teaching and learning), the ancestors of the Native Hawaiian community were diligent about preserving the keys to their genealogical legacies within more than 120,000 pages of Hawaiian-language newspapers. This collective repository is a resource that helps the Office of Hawaian Education (OHE) rethread Hawaiian education into the tapestry of traditional sources of knowledge production to improve sustainability (cultural, intellectual, environmental, political, etc.) for all learners. OHE uses a theory of change that engages primary and secondary sources, quantitative and qualitative data, in action research that informs Why contemporary circumstances exist, What those contemporary circumstances are, Where we want Hawaiian education to go, and How we are going to get there.
