Many infectious diseases can be transmitted through direct contact. If hands are contaminated with pathogens, especially when they are soiled with respiratory discharge or faecal matters, diseases include dysentery, cholera, hepatitis, influenza, and hand, foot and mouth disease can be spread easily. Observance of hand hygiene is the prerequisite of the prevention of the spread of communicable diseases. Using soap and water or rub hands with alcohol-based handrub can achieve hand hygiene.
Hand hygiene is the single most important measure of reducing the spread of diseases. Members of the public are advised to clean hands with liquid soap and water when they are visibly soiled or likely contaminated with blood and body fluid. When hands are not visibly soiled, could be cleaned them with 70-80% alcohol-based handrub.
In general, we should wash hands with soap and water when hands are visibly dirty or visibly soiled with blood, body fluid, after using the toilet or changing the diapers. When hands are not visibly soiled, 70-80% alcohol-based handrub is also an effective alternative.
According to the World Health Organization’s recommendation, most alcohol-based handrubs contain either ethanol, isopropanol or n-propanol, or a combination of two of these products.
How can we ensure hand hygiene performance are being conducted up to recommendation? How about night duties clinical colleagues, or in-a-hurry manner? A specially designed water basin with 7 steps reminder liquid-crystal display plus at least of 20 seconds hand washing times counting would be a better alternative to remind on good hand hygiene along with proper performance. Generalization of proper hand hygiene altitude by installing such on city around and all health care areas can reinforce the hand hygiene compliance.

Mental health is one of the crucial health issues among Hong Kong youth population causing several youth suicides. Adolescents commonly suffer from anxiety and depressive mood by virtue of high academic pressure, interpersonal relationships and insufficient sleep. Mood change is the early sign of the mental health problems especially anxiety and depression. Colouring mandalas is one of the strategies for promoting the positive mood. Advance in information and communication technology, mobile health (m-health) rapidly grows worldwide since the penetration of smartphone rises swiftly especially among the adolescents. Majority of them use the smartphone not only for communication but also for entertainment. Using mobile health can be a powerful intervention for them to promote positive mood so mood change and colouring mandalas mobile apps offers a platform for monitoring daily mood changes and uploading colouring mandalas. It also provides knowledge about maintenance of positive mood and explores the effects of the colouring mandalas on the mood changes and promoting positive mood. The system pioneers the development of smart mental health.

We present an integrated approach toward Monitoring-driven Life-cycle assessment of wind turbine structures. A major challenge in efficient condition assessment and residual life prediction for such systems lies in their continual exposure to highly stochastic loads due to varying environmental and operational conditions.  In the context of the ERC StG project WINDMIL, we develop tools that are able to tackle the lack of precise loading information, as well as the operational, environmental and modelling uncertainties, toward the structural health monitoring, damage detection and life-cycle assessment for wind turbine components across two temporal scales, namely the short-term (gusts, extreme turbulence, faults) and long-term (fatigue). We propose a novel framework that combines an easily deployed and relatively cheap sensor network, with state-of-the-art data processing methodologies with the standard stream of condition monitoring data (SCADA). We present the main thesis of this framework and illustrate its various building blocks, such as physics-based and data-driven modelling, data fusion, fatigue and life cycle assessment and decision-making process.

Smart health is increasingly discussed worldwide to improve the quality of the life in the community since the rapid development of mobile health (m-health) and information technology. The growth of m-health becomes a great concern issue especially among the young population because the penetration of mobile phone or smart phone among youth is very high so mobile health on bowel habit can improve the adolescent health issue regarding constipation. In Hong Kong, the prevalence rate of constipation among secondary students is high than that in Taiwan because of high academic pressure, unhealthy diet and physical inactivity. Lack of physical activity can be one of the risk factors causing constipation. Majority of secondary students focuses only on issues regarding their studies instead of the healthy bowel habit and increasing physical activity. Bowel habit mobile monitoring system provides a platform for exploring the daily bowel habits and promoting physical exercise to increase the bowel movement. The purpose of the study is to increase the awareness on changing in bowel habit and ameliorate cognitive aspects of the maintenance healthy bowel habit among the youth. It also probes the relationship between the bowel habit mobile monitoring system and the quality of the life of the adolescent. The system could be useful for further development of the m-health regarding the healthy bowel habits for the community.
