    Purpose – The purpose of this case study is to examine the rationality for taking an enterprise approach towards metadata’s development. It outlined and discussed the benefits and challenges involved from both theoretical and practical perspectives. Methodology – The data for this case study is collected through a one on one interview method. The findings were discussed and analysed with other literature. Findings – Taking an enterprise wide approach towards the development of metadata offers both short-term and long-term benefits to the Ministry. In particular, the short-term benefits include efficiency in time to answer, re-use and re-purposing of existing information. The long-term benefits are the ability to operate at a strategic level with its data and information. On the other hand, the different level of understanding towards the concept of metadata at present, in addition to a lack of a clear guardianship from a data perspective has lead to challenges in gaining a level of active contribution and ongoing maintenance. This report suggested that it is essential for the Ministry to maintain a constant marketing style of communication to promote the understanding of the metadata and to incorporate the principle of data stewardship in managing the component of metadata mapping. Value – This case study provides value by explaining the concept and outlining the key benefits and issues involved to those organisations discovering the topic of metadata management for the first time. This case study adds additional value by offering rare insights into taking an enterprise approach towards the development of a business metadata, offering practical learning and suggestions for other organisations that are embarking on a similar journey

    香港老年保障制度改革模式

    1971年,香港已經建立了綜合援助計劃,以幫助貧困長者,並在2000年12月開始執行強積金計劃。從目前的情況來看,香港已經建立多支柱的老年保障體系,SSA和CSSA為長者提供基本生活保障,MPF制度為正規部門的就業人員提供年金保障,ORSO制度為正規部門就業人員提供額外保險。但此體系還相當的不完善,並不能給長者提供足夠的、可承受和可持續的養老金。 因此,面對日益嚴重的人口老齡化和老年貧困問題,香港老年保障制度也面臨極大的資金壓力,並處於老年保障支出越來越多,老年貧困問題制度越來越嚴重的尷尬局面。本次研究針對這些突出問題,結合國際老年保障制度改革的經驗,並根據香港實際情況,提出適合香港本身的老年保障制度模式,即提高MPF繳費率,擴大繳費基數,改革個人賬戶積累發放辦法,並將SSA由全民平均津貼制改為收入調查津貼制。 本文運用世界銀行開發的PROST軟件,從精算的角度進行具體成本分析。通過對未來70年的成本預測,以及與現制度的成本比較,以判斷此改革模式是否具有長期財務可持續性和可行性。通過此次研究,希望能為香港的老年保障制度提供一個雙嬴的方案,既可提供長期的老年保障資金支持,又可促進經濟持續發展

    Real-Time Illegal Parking Detection System Based on Deep Learning

    The increasing illegal parking has become more and more serious. Nowadays the methods of detecting illegally parked vehicles are based on background segmentation. However, this method is weakly robust and sensitive to environment. Benefitting from deep learning, this paper proposes a novel illegal vehicle parking detection system. Illegal vehicles captured by camera are firstly located and classified by the famous Single Shot MultiBox Detector (SSD) algorithm. To improve the performance, we propose to optimize SSD by adjusting the aspect ratio of default box to accommodate with our dataset better. After that, a tracking and analysis of movement is adopted to judge the illegal vehicles in the region of interest (ROI). Experiments show that the system can achieve a 99% accuracy and real-time (25FPS) detection with strong robustness in complex environments.Comment: 5pages,6figure
