Conclusion

The NTUH new portal explores the dynamic, hierarchical drop-down navigation menu to

visualize function linkages by simply managing the configuration files. The DDNM

rendering is flexible for space usage and enlarges the capacity of URL links. It leads the

portal contain over 300 function links as well as two bulletins in one web page. The XML

formatted configuration files are designed to automate function linkages with access control,

linkage modes and multi-server redirections, as well as target control. The new portal

generates the main page effectively and efficiently. In addition, the portal supports front end

integration for NTUH numerous systems, platforms applying the SSOS scheme. Therefore,

the portal provides a unique entrance for NTUH HIS infrastructure. The infrastructure

supports the availability of any data, at any time, from any place dynamically.

The NTUH HIS has been developed from the ground up to be an available, robust, reliable,

secure, interoperable, and service-oriented architecture. Moreover, the NTUH HIS is an

innovation designed to address the continuously changing and demanding natures of

today’s healthcare environment in Taiwan. It presents a solution to perform challenges

imposed by heavy messaging traffic that is threatening the viability of Web-Services (.NET)

implementations. As a result, capital expenditures are controlled and the return on

investment is shorter.

In summary, the NTUH HIS portal is a vehicle driven to support integrated access to

information needed by Hospital constituents, whether they are students, staff, or faculty.

Furthermore, the additional tools, techniques empower medical practitioners to customize,

fulfil their experiences more comprehensively. The DDNMLog service provides a dynamic

function linkage usages monitoring and allows just-in-time (shortcuts) accesses for users. On

the other hand, NTUH HIS Portal is a large, complicated, heavily interlinked web site; it is

likely to be disoriented. However, the Portal is a visible, hierarchical tree topology, and

immediately accessible; under the circumstances, the site map is significantly

accommodating (Yip, 2004; Danielson, 2002). As the portal continues to be developed and

enhanced, the new features can be added on a regular basis.

The aspects of the NTUH Portal accessibility, i.e., visual structure, colour contrast, and text

size, in compliance with Web Content Accessibility Guidelines 2.0 (WCAG 2.0, 2008), are

under preliminary investigation.
