Prognostics and Health Management(PHM) has become a very important tool in modern commercial aircraft. Considering limited built-in sensing devices on the legacy aircraft model,one of the challenges for airborne system health monitoring is to find an appropriate health indicator that is highly related to the actual degradation state of the system. This paper proposed a novel health indicator extraction method based on the available sensor parameters for the health monitoring of Air Conditioning System(ACS) of a legacy commercial aircraft model. Firstly, a specific Airplane Condition Monitoring System(ACMS) report for ACS health monitoring is defined. Then a non-parametric modeling technique is adopted to calculate the health indicator based on the raw ACMS report data. The proposed method is validated on a single-aisle commercial aircraft widely used for short and medium-haul routes, using more than 6000 ACMS reports collected from a fleet of aircraft during one year. The case study result shows that the proposed health indicator can effectively characterize the degradation state of the ACS, which can provide valuable information for proactive maintenance plan in advance. 展开更多

Background:Preliminary evidence among adults suggests that the ways in which individuals think about their physical activity(PA)behavior is more closely associated with their well-being than self-reported PA.This study therefore aimed to examine whether and how self-reported PA and personal beliefs about suffbcient PA are associated with sleep and psychological functioning in a sample of Swiss adolescents,using both cross-sectional and prospective data.Methods:An overall sample of 864 vocational students(368 girls,17.98±1.36 years,mean±SD)was followed prospectively over a 10-month period.At each measurement occasion,participants filled in a series of self-report questiocnaires to assess their PA levels,their personal beliefs about whether or not they engage in sufficient PA,sleep(insomnia symptoms,sleep quality,sleep-onset latency,and number of awakenings),and psychological functioning(depressive symptoms,quality of life,perceived stress,and mental toughness).Results:Adolescents who believe that they are sufficiently physically active to maintain good health reported more restoring sleep.No differences in sleep were found between adolescents who meet PA recommendationsvs.those who do not.Additionally,adolescents who believe that they were sufficiently physically active also reported better psychological functioning.This close relationship between adolescents5 beliefs about their PA involvement and their sleep and psychological functioning was corroborated in the prospective analyses.Conclusion:Cognitive factors should be studied more intensively when elucidating the relationship among PA,sleep,and psychological functioning in young people,particularly when aiming to develop new exercise interventions targeting psychological outcomes. 展开更多

AIM: To review vision health situation of Iranian community, analyze its determinants, and discuss the adopted improvement strategies by the Iran Ministry of Health and Medical Education(MOHME). METHODS: This was a rapid situation analysis with a qualitative approach in three parts of recognition, orientation and implementation. The data were gathered via review of upstream documents, national and international experiences, and experts and stakeholders’ opinions. RESULTS: Eradicating trachoma, increasing human resources, increasing educational and research centers and promotion of ophthalmic technologies were important achievements in the field of vision health in Iran. Through these achievements, it seemed that the pattern of causes of blindness and low vision was similar to that of the developed countries. However, the review of Iranians’ vision health indicators showed that a considerable percent of the blindness and low vision was avoidable through a national program demanding 3 types of interventions in social determinants of health(SDH), community education, and increasing the access to health care services by integrating the necessary services in primary health care system. CONCLUSION: Managing the issue requires attentions from a national committee for preventing blindness with participation of all stakeholders, implementing a national survey on vision health, preparation of the primary level health centers including employment and education of community health workers(Behvarzes), optometristsand general practitioners, fair distribution of specialized human resources and establishing at least one specialized center in each province for referring patients from the primary levels. 展开更多

Background: Although evidence on the health effects of sedentary behavior(SB) has grown systematically in recent years, few developing countries have reported population levels of SB, especially in South America. Our objective was to describe time spent sitting in a representative sample from Chile categorized by age, gender, educational level, and body mass index(BMI).Methods: A national health survey was conducted in Chile in a nationally representative sample(n = 5411) in 2009-2010. Sitting time(ST) was measured with the Global Physical Activity Questionnaire Version 2.Results: Data were from 5031 participants(43.26±0.41 years, mean±SE;40.3% male). Overall, there were no gender differences in mean ST(men: 158.10±5.80 min/day, women 143.45±4.77 min/day;p = 0.05). ST was lower in those who lived in rural areas compared with urban areas(99.4 min/day vs. 160.0 min/day;p = 0.001). ST increased significantly with increasing BMI, but only in men(p = 0.009), and was positively related to years of education in both men and women(p < 0.0001).Conclusion: The findings were different from those reported in other countries and contexts, reinforcing the need for international surveillance and monitoring over time to inform policy makers. Differences in ST across different groups emphasize the need to develop tailored messages and interventions for reducing ST in different population subgroups. 展开更多

The health and mental well-being of children and adolescents in general is good.Most are satisfied with their lives,perceive their health to be good,and do not regularly suffer from health complaints.The main problems of the first half of the 20th century,such as acute infections and high infant mortality,have diminished in importance.Instead of physical disorders,mental illness accounts for a large and growing share of ill health among children and adolescents in Europe.Including emotional problems,this may conduct problems and learning disabilities came to the fore in the middle of the last century.Currently,the frame of mental health and socio-economic influences on health has risen to achieve importance within child and adolescent health.World Health Organization(WHO)declared that young people’s mental health is a key area of concern to which professionals and policy-makers must direct their attention.Focusing only on mental health disorders does not give the whole picture of the state of mental health among young people.A general problem is the predominant understanding of mental health as the absence of mental disorder.Risk factor research has focused on mental health problems rather than strengths and positive outcomes.Consideration of resilience has emerged from research indicating that a proportion of young people had a positive life trajectory despite having faced diverse potentially harmful life experiences.Worldwide up to 20%of children and adolescents suffer from disabling mental health problems:Mental health of adolescents and youth,it is a very problematic issue that is not expressed only with elements.This required a lot of analysis and statistic to arrive for a result which serves to us for knowing and preventive the problem.As an issue,we must identify two major part of this:What is mental health(definition,cause,diffusion,ages,and preventive)?And what can we do to improve the mental health of Adolescents and Youth(family,society,hospitals,school,and public places)?The estimates of psychologic 展开更多

Flavonoids are widely-distributed polyphenolic secondary metabolites with diverse biological activities in plants and benefit human health as protective dietary agents. They participate in plants’responses to harsh environmental conditions and effectively regulate the cell differentiation and growth. In plants, the majority of their functions are attributed to their strong antioxidative properties. Similarly, dietary flavonoids protect the human body against free radicals which are associated with the development of cancer and atherosclerosis. Plants rich in polyphenols have been used to cure various diseases because of their antibacterial, antiviral, antifungal and anticancer properties. This review summarizes the up-to-date research trends and development on flavonoids and its derivatives, working mechanisms and potential functions and applications particularly in relation to plant protection and human health. Towards the end, notable concluding remarks with a close-up look at the future research directions have also been presented briefly. 展开更多
