INTRODUCTIONAlcohol has been used in society over centuries and all over the world for its mood-lifting properties and taste. It is probably ,however ,the commonest drug of abuse world-wide and unfortunately causes considerable morbidity, mortality and social disruption .In 1990 the cost tl the USA was more than $ 100 billion and 100 000 lives.The relationship between alcohol and mankind is well documented from the earliest tines .

A procedure is proposed whereby input and hysteretic energy spectra developed for single-degree-of-freedom （SDOF） systems are applied to multi-degree-of-freedom （MDOF） steel moment resisting frames. The proposed procedure is verified using four frames, viz., frame with three-, five-, seven- and nine-stories, each of which is subjected to the fault- normal and fault-parallel components of three actual earthquakes. A very good estimate for the three- and five-story frames, and a reasonably acceptable estimate for the seven-, and nine-story frames, have been obtained. A method for distributing the hysteretic energy over the frame height is also proposed. This distribution scheme allows for the determination of the energy demand component of a proposed energy-based seismic design （EBSD） procedure for each story. To address the capacity component of EBSD, a story-wise optimization design procedure is developed by utilizing the energy dissipating capacity from plastic hinge formation/rotation for these moment frames. The proposed EBSD procedure is demonstrated in the design of a three-story one-bay steel moment frame.

BACKGROUND: Currently there is very limited data in the literature assessing the prevalence of antihistamine prescription, and there is no local prevalence data about the prescription of antihistamine agents among primary practitioner and emergency physicians. The objectives are 1) to report the prevalence of antihistamine prescription for children less than 6 years old with acute upper respiratory infection and 2) to explore the associated factors for the prescription ***: This is a cross-sectional study. All consecutive cases of paediatric patients aged 6 or below who presented to the emergency department during a study period of one week from April 1 to July 4, 2009 with diagnosis of acute upper respiratory infection were included. Totally 162 patients were ***: Among the 162 cases, 141(87%) patients were prescribed one antihistamine of any group. Sixty(37%) patients were prescribed two or more antihistamines. In multivariate logistic regression model, age was found to be signi? cantly(P<0.001) associated with multiple antihistamine prescription(OR=1.042, 95%CI=1.02 to 1.06). Years of graduation of attending physician for more than 5 years was also a strong predictor of multiple antihistamine prescription(OR=4.654, 95%CI=2.20 to 9.84, P<0.001).CONCLUSION: In the local emergency department, patients' age and the years of graduation from medical school of the attending physician were predictors of multiple antihistamine prescription for acute upper respiratory infections for children aged less than 6.

Six common algal fatty acids （FAs） with different numbers of double bonds, lipophilic fractions and proteins extracted from the diatom Navicula pelliculosa and algal ceils were chlorinated to evaluate their potential in generating disinfection by-products （DBPs）. The result showed that the more double bonds in the FAs, the higher the amounts of chloroform and dichloroacetic acid （DCAA） produced, but such a pattern was not observed for trichloroacetic acid （TCAA）. Based on the previously reported composition of fatty acids in algal lipids, the DBP generation potentials of algal lipids were calculated. These predicted values were much lower than those measured in the chlorinated algal lipophilic fraction, suggesting unknown lipophilic fraction（s） served as potent DBPs precursors. Another calculation attempted to predict DBP production in algal cells based on algal lipid and protein composition, given quantified measured DBP production per unit algal lipid and proteins. The analysis showed that the observed DBP production was similar to that predicted （〈 35% difference）, suggesting that algal biochemical compositions may serve as a bioindicator for preliminary estimation of chloroform, DCAA and TCAA formation upon chlorinating algae.

The Historic Urban Landscape(HUL)Recommendation(UNESCO 2011)suggests that heritage management should be holistic,integrated,people-centred and focused on sustainable development *** tangible and intangible heritage should be taken into account,allowing for appropriate change over time.A variety of stakeholders should be involved in planning processes,including all levels of government,NGOs and *** dialogue and mediation,as well as tools such as documentation,inventorying and mapping should be used to identify multiple layers of *** the Recommendation thus offers a wonderful opportunity to develop consultative,bottom-up,integrated planning for sustainable development in urban *** paper suggests that one barrier to integrating management planning for tangible and intangible heritage is a persistent confusion about what‘intangible heritage’is and why it deserves *** it the values that local communities associate with their environment(‘intangible values’),or is it cultural practices that they happen to perform in that environment(intangible cultural heritage,or ICH)?Should‘intangible heritage’be managed as an attribute attesting to the authenticity of tangible fabric,or as a subject of safeguarding in its own right?If it means all these things at the same time,why is the same concept being used for so many different ideas and what are the consequences?The paper will suggest that a clearer conceptual understanding of intangible heritage is necessary to effectively integrate it into urban management strategies under the HUL approach.
