Plan de negocio para el desarrollo e implementaci?n de restaurant de comida saludable
El panorama actual en que se encuentra el problema de salud como el sobrepeso y obesidad, genera una necesidad insatisfecha (h?bitos alimenticios saludables econ?micos), que se constituye en una oportunidad de negocio para la apertura de Fresh Food donde se presenta como una alternativa a restaurantes que se encuentren alineadas a las nuevas tendencias alimenticias como es de comida saludable o Fast good. La investigaci?n es mixta (Cualitativo ? Cuantitativo), de tipo no experimental, transversal y descriptivo teniendo como marco poblacional de 480 estudiantes universitarios, a quien se le pregunt? sus preferencias y h?bitos de consumo de alimentos. Entre los resultados de este se dedujo que la falta de informaci?n por parte de los restaurantes que les brinda los alimentos a los estudiantes es un aspecto importante para el negocio, as? como la forma de prepararlos. Como resultado se detect? que existe un potencial de 42.9% de estudiantes que no ha escuchado hablar de restaurantes de esta naturaleza, adem?s de tener un perfil del alumno respecto a sus caracter?sticas de consumo, fue importante determinar que el precio promedio seria de 13 soles. Despu?s de haber analizado la apertura de Fresh Food en Surco en zona aleda?a a universidades, observamos que es viable y se sustenta
Recursive ensemble feature selection provides a robust mRNA expression signature for myalgic encephalomyelitis/chronic fatigue syndrome
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a chronic disorder characterized by disabling fatigue. Several studies have sought to identify diagnostic biomarkers, with varying results. Here, we innovate this process by combining both mRNA expression and DNA methylation data. We performed recursive ensemble feature selection (REFS) on publicly available mRNA expression data in peripheral blood mononuclear cells (PBMCs) of 93 ME/CFS patients and 25 healthy controls, and found a signature of 23 genes capable of distinguishing cases and controls. REFS highly outperformed other methods, with an AUC of 0.92. We validated the results on a different platform (AUC of 0.95) and in DNA methylation data obtained from four public studies on ME/CFS (99 patients and 50 controls), identifying 48 gene-associated CpGs that predicted disease status as well (AUC of 0.97). Finally, ten of the 23 genes could be interpreted in the context of the derailed immune system of ME/CFS
Population and fertility by age and sex for 195 countries and territories, 1950–2017: a systematic analysis for the Global Burden of Disease Study 2017
Background: Population estimates underpin demographic and epidemiological research and are used to track progress on numerous international indicators of health and development. To date, internationally available estimates of population and fertility, although useful, have not been produced with transparent and replicable methods and do not use standardised estimates of mortality. We present single-calendar year and single-year of age estimates of fertility and population by sex with standardised and replicable methods. Methods: We estimated population in 195 locations by single year of age and single calendar year from 1950 to 2017 with standardised and replicable methods. We based the estimates on the demographic balancing equation, with inputs of fertility, mortality, population, and migration data. Fertility data came from 7817 location-years of vital registration data, 429 surveys reporting complete birth histories, and 977 surveys and censuses reporting summary birth histories. We estimated age-specific fertility rates (ASFRs; the annual number of livebirths to women of a specified age group per 1000 women in that age group) by use of spatiotemporal Gaussian process regression and used the ASFRs to estimate total fertility rates (TFRs; the average number of children a woman would bear if she survived through the end of the reproductive age span [age 10–54 years] and experienced at each age a particular set of ASFRs observed in the year of interest). Because of sparse data, fertility at ages 10–14 years and 50–54 years was estimated from data on fertility in women aged 15–19 years and 45–49 years, through use of linear regression. Age-specific mortality data came from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 estimates. Data on population came from 1257 censuses and 761 population registry location-years and were adjusted for underenumeration and age misreporting with standard demographic methods. Migration was estimated with the GBD Bayesian demographic balancing model, after incorporating information about refugee migration into the model prior. Final population estimates used the cohort-component method of population projection, with inputs of fertility, mortality, and migration data. Population uncertainty was estimated by use of out-of-sample predictive validity testing. With these data, we estimated the trends in population by age and sex and in fertility by age between 1950 and 2017 in 195 countries and territories. Findings: From 1950 to 2017, TFRs decreased by 49\ub74% (95% uncertainty interval [UI] 46\ub74–52\ub70). The TFR decreased from 4\ub77 livebirths (4\ub75–4\ub79) to 2\ub74 livebirths (2\ub72–2\ub75), and the ASFR of mothers aged 10–19 years decreased from 37 livebirths (34–40) to 22 livebirths (19–24) per 1000 women. Despite reductions in the TFR, the global population has been increasing by an average of 83\ub78 million people per year since 1985. The global population increased by 197\ub72% (193\ub73–200\ub78) since 1950, from 2\ub76 billion (2\ub75–2\ub76) to 7\ub76 billion (7\ub74–7\ub79) people in 2017; much of this increase was in the proportion of the global population in south Asia and sub-Saharan Africa. The global annual rate of population growth increased between 1950 and 1964, when it peaked at 2\ub70%; this rate then remained nearly constant until 1970 and then decreased to 1\ub71% in 2017. Population growth rates in the southeast Asia, east Asia, and Oceania GBD super-region decreased from 2\ub75% in 1963 to 0\ub77% in 2017, whereas in sub-Saharan Africa, population growth rates were almost at the highest reported levels ever in 2017, when they were at 2\ub77%. The global average age increased from 26\ub76 years in 1950 to 32\ub71 years in 2017, and the proportion of the population that is of working age (age 15–64 years) increased from 59\ub79% to 65\ub73%. At the national level, the TFR decreased in all countries and territories between 1950 and 2017; in 2017, TFRs ranged from a low of 1\ub70 livebirths (95% UI 0\ub79–1\ub72) in Cyprus to a high of 7\ub71 livebirths (6\ub78–7\ub74) in Niger. The TFR under age 25 years (TFU25; number of livebirths expected by age 25 years for a hypothetical woman who survived the age group and was exposed to current ASFRs) in 2017 ranged from 0\ub708 livebirths (0\ub707–0\ub709) in South Korea to 2\ub74 livebirths (2\ub72–2\ub76) in Niger, and the TFR over age 30 years (TFO30; number of livebirths expected for a hypothetical woman ageing from 30 to 54 years who survived the age group and was exposed to current ASFRs) ranged from a low of 0\ub73 livebirths (0\ub73–0\ub74) in Puerto Rico to a high of 3\ub71 livebirths (3\ub70–3\ub72) in Niger. TFO30 was higher than TFU25 in 145 countries and territories in 2017. 33 countries had a negative population growth rate from 2010 to 2017, most of which were located in central, eastern, and western Europe, whereas population growth rates of more than 2\ub70% were seen in 33 of 46 countries in sub-Saharan Africa. In 2017, less than 65% of the national population was of working age in 12 of 34 high-income countries, and less than 50% of the national population was of working age in Mali, Chad, and Niger. Interpretation: Population trends create demographic dividends and headwinds (ie, economic benefits and detriments) that affect national economies and determine national planning needs. Although TFRs are decreasing, the global population continues to grow as mortality declines, with diverse patterns at the national level and across age groups. To our knowledge, this is the first study to provide transparent and replicable estimates of population and fertility, which can be used to inform decision making and to monitor progress.

The publication contains a compilation of lifelong learning innovations. Sharing of experiences and strategies on lifelong learnings integral to UIL\u92s mission and in line with this spirit, the three year TRALL project has shown the importance of promoting synergies instead of the usual dispersion of efforts in the Latin American region. Such projects as TRALL and the resulting publicationare an important way to add value to the many learning reforms different actors are conducting in the different countries in the Latin American region. Imparting and taking on board good practices lead to common understanding and convergence in outlook. At the same time, learning from different country contexts is considered to be relevant for promoting the idea of social diversity.
The report Learning to Be commissioned by UNESCO in 1972 (Faure et al., 1972) advocated lifelong education in both developed and developing countries, recognising education as universal and lifelong, and open to all. The UNESCO Report Learning: the Treasure Within (Delors et al., 1996), acknowledged
lifelong learning as one of the guiding and organising principles of educational action and reform that underlines the essential role learning plays for both society and individuals.Despite the integrative understanding lifelong learning promoted since 1972, today most education systems are still not in a position to offer quality lifelong learning opportunities for all. Making it a reality implies holistic and sector-wide educational reform involving all sub-sectors and education levels of the education system to ensure the creation of learning opportunities in all settings or delivery modalities (formal, non-formal and informal) for people of all ages, and meeting a wide range of learning needs. Recent developments have reinforced the relevance of lifelong learning. These include an increasingly globalised world, the need for maintain peace and security, the introduction of new technologies, the
exponential growth and changing nature of information, demographic shifts and social transformations, climate change and sustainable development, and the need of citizens to upgrade competences to meet labour market, social and environmental demands. Lifelong learning policies in the Latin American region need to be supported by broad social consensus,legislative instruments and coordination mechanism. As lifelong learning activities no longer fall exclusively
within the domain of Ministries of Education, a mechanism for facilitating collaboration among various sectors and stakeholder is indispensable. Certain support structures are needed to facilitate lifelong learning. These include on the one hand, a full range of provision of education and learning opportunities,
including guidance and counselling; as well as effective information and communication tools, and conducive learning environments and resources. To facilitate lifelong learning and provide incentives for learners, a learning outcomes-based qualifications framework and a coordinated approach to assessment and recognition of learning outcomes in non-formal and informal settings are required
