An assessment of the condition of nine engraved sites in the Hong Kong Special Administrative Region

Nine engravings in the hinterland around Hong Kong Island have been studied independently by the authors, as part of an overall assessment of current management practices, the state of the engravings, conservation impacts and future survival. Four independent studies were commissioned in 2009 by the Hong Kong Heritage Museum in conjunction with the Antiquities and Monuments Office who have legislative responsibility for all archaeological sites within the Hong Kong Special Administrative Region. The sites have received varying levels of protection in the form of roofs, fences, and screens, and in more recent times, a range of conservation treatments aimed at prolonging their life and improving legibility. This paper reviews the state of the engravings from the point of view of protection and presentation and considers the effectiveness of the infrastructure in mitigating what are often conflicting needs. Modern conservation treatments must be considered in several dimensions: their effectiveness and durability in an aggressive climate, given that the engravings have survived for 3000 years, and the feasibility and cost of maintaining such treatments over the next 3000 years and longer. This paper describes field observations rather than measured data, due to the nature of the commission, highlighting the value of intelligent observation as an investigative tool. The main focus of the paper is on the impact of protective shelters and applied treatments as observed during two of the independent surveys, concluding that protection must address all environmental and visitor impacts to be fully protective.     

大学生合理安排时间的技巧

大学阶段的生活与中学时有很大差别:老师不会再时刻敦促你学习,课堂上不会再留成摞的作业,住校所以父母再也不能每日操心你的作息。在无人管束后,有些同学可能会感觉无所适从,从而放松学习,荒废大学四年的光阴。尽管没有他人的约束,但我们做事仍应有计划性,合理安排学习和休息的时间并不断奋进。
