    All listed companies need to follow the Generally Accepted Accounting Principles while reporting their results to the prime lender Central Bank of Oman and Capital Market Authority, which is the financial regulator in the country, as well as the shareholders. Also all listed companies need to follow the International Finance Reporting Standards issued by the International Accounting Standard Board (IFRS, 2014). . It also lends objectivity and relevance to accounting information especially when the users have conflicting objectives (Flood, 2014).Financial statement analysis helps identify the trends between financial statement items which the internal management and external users like creditors, investors, suppliers can use to take decisions about investing in the company. Some of the common methods used for financial statement analysis are trend analysis, common‐size statements, and ratio analysis. ... Less

    This report is based on the following case study -

    All questions relate to the following Case Study.

    A new type of home-based elder care model, called Virtual Elder Care Home or Elder Care Home without Walls, has gained popularity in China. It features home care agencies providing a wide range of personal care and homemaker services in elders’ homes. Services are initiated by phone calls to a local government–sponsored information and service center, which then directs a qualified service provider (a staff member) to the elder’s home.

    • Participating providers (Virtual Elder Care Home or Elder Care Home without Walls organisations) contract with the local government and are reimbursed for services purchased by the government on behalf of eligible care recipients, the majority of whom are vulnerable. Since its inception in 2007 in the city of Suzhou, in eastern China’s Jiangsu Province, the Virtual Elder Care Home model has spread to many parts of the country, including Gansu Province in northwest China. (sourced from Z Feng, C Liu, X Guan, V Mor. China's Rapidly Aging Population Creates Policy Challenges In Shaping A Viable Long-Term Care System. Health affairs (Project Hope), 2012 - ncbi.nlm.nih.gov)

    You have been ed by the Ningbo Virtual Elder Care Service to research and document requirements for a computer system to help establish the new service in that city. The service is already functioning but using paper-based systems. Currently the HVCS (home-visiting care staff) need to come to the office in the morning to receive the list of clients to visit along with details of their conditions and the services they require. If there is a change then the call centre staff try to the HVCS by phone. The HVCS complain that they do not have all the information they need when visiting a client in terms of clinical history, family member details, or means of referring the client to other services including doctors when needed. They also complain they need to keep manual records of clients and of the services they provided. At the end of the day the HVCS deliver their time-sheets with times and some details of the visits to clients.

    System Capabilities
    The new system should do the following:
    • Deliver the daily work schedule on-line to the mobile work-force along with relevant data about the clients and automatically generate the time-sheets.

    Describe the components involved in a traditional drill and blast mining cycle and those involved in a continuous mechanised mining cycle. What advantages and disadvantages do both systems of mining have?

    Question 21

    The diagram below illustrates the amount of coal that is left intact after mining in pillars and the amount of coal that is extracted in the rooms. If a1 = 20m, a2 = 22.5 m, b1 = 5m and b2 = 4.5m determine the recovery ratio in a 2.5 m coal seam.



    Question 22

    What do the terms transverse and longitudinal mean with respect to the direction of mining within an orebody?

    Question 23

    Show with the aid of diagrams the development, production and filling phases for a typical open stoping mining setup. What advantages does filling of the stope give?
