With the rapid development of smart phones and mobile devices[1] it becomes verypopular that people more prefer to access the information through this flexible waySo the requirement of proper interface according to different devices become a hottopic and the goal will motivate the use of RWD[2](Responsive Web Design) It aimsat crafting sites to provide an optimal viewing experience in easy reading andnavigation with a minimum of resizing panning and scrolling across a wide range ofdevices such as from desktop computer monitors to mobile phones Whatrsquos more nowdays E-health has gradually aroused great attention all over world And the modernday healthcare needs and delivery is complex and the use of ICT[3] has made somepositive impact in attending to such needs that e-health applications require Theproject is about E-health[4] web application framework and responsive web designwhich base on the cloud platform This idea comes from instructor Dr Eric Chenrsquosproject proposal Though there are some existing researches in above fields there isless or almost none related work which combines these fields to provide a basic framespecifically focusing on the e-health Right information at right time saves lives Soan E-health web application framework and platform based on the cloud is a part ofinformation and communication technology supported self-care system for thediabetes This project will closely collaborate with another group working datacollection and presentation application The new related work in above fields worth tobe done from the view of reality and research

There are many definitions for E-Health until now but still there is no consensus onone common definition This is because of its ubiquitous and dynamic nature TheE-health information are widely used with different meanings and purposes In ourwork we develop the E-health application mostly used for diabetes patient

Joaquin (2010) who is one of the World health organization members definedE-health as the use of information and communications technologies (ICT) in favor ofhealth and health-related fields containing health-care services health supervisionhealth literature and health self-management education knowledge and research andstated that E-health has the potential to greatly improve health service efficiency itshould expand or extend treatment delivery to more than thousands of patients indeveloping countries and also improve patient results[6] In another word Mitchell defined that ldquo the combined use of electroniccommunication and information technology in the health field need to be described bya new term The use in the health sector of digital data transmitted stored andretrieved electronically both at the local site and at a distance for clinical educationaland administrative purposes rdquo(Mitchell 1999) [7]Sweden America Britain and the rest of Europe has experienced a great proliferationof health care-related websites most of which present disinformation and misleadingguidance(Fogg et al 2001)[8] And research suggests that the E-health web usersexpress the strong desire to own a online website which is used for theirself-management and directly getting advice from the doctor So the self-managementand interoperability are mostly focused in our project

There are many advantages in using E-Health concepts One key example isElectronic Health Records Before E-health came into use we used paper basedsystem to record patient health data These paper based system may have errorswhile entering the patient records into papers Coming to E-health data storeelectronically and it is more simpler and efficient way of data storing (Haumlyrinen2008)[9] Grogan stated that there is an evidence to suggest that E-health providemore complete and error free methods for storing patient data (Grogan 2006)[10]

By using E-health there are many benefits to different people such as doctorspatients etc For example doctorrsquos orders can be placed electronically which avoidwrong elucidation of hand wrote orders And with the help of E-health most doctorsreduces the time of locating and reading patient health information To the patient

they can begin to be gradually aware of the importance of self-care managementMoreover it is also convenient for maintaining only with some experts in medical andapplication developers

The followings list are the main barriers to E-health

231231231231 OperationalOperationalOperationalOperational BarriersBarriersBarriersBarriersThis area of concern relates to the interoperability of systems which e-Health aims toprovide (John 2009)[11] First a system has to be developed with an interfaceallowing existing computer system to communicate with new system which e-Healthwill introduce Second there must be a common standard electronic language to crosscommunicate between different healthcare organization about the medical data suchas patient records and hospital internal record There must be formal agreement onwhat the best method to communicate such data between organizations (Hill et al2007)[12]

232232232232 CostBenefitCostBenefitCostBenefitCostBenefit BarriersBarriersBarriersBarriersAs the name suggest it is the barrier related to the cost in implementing e-Healthsolutions whether it is feasible in-terms of cost wise ie do the benefit of e-Healthoutweigh the cost required to implement E-health From the technical side theimplementation of E-health solutions is clearly advantageous in comparison with pastmethods such as the paper-based record keeping systems but from the healthcareorganization side these benefits may not outweigh the cost of implementinge-Health solutions The cost of implementing e-Health solutions can be tens ofthousands of dollars and this does not even include the requirement of hiring teamsof IT professionals to support and maintain the software throughout its life cycle(Mearian 2010)[13]

Most European governments have set up combined systems of healthcare insurancein which public compulsory health insurance coexists with private companies (whichare optional most of the time) Globally the European population is aging whichtranslates into an increasing demand for healthcare and an increased cost of treatmentOn a global basis many governments in Europe are transferring expenses from publicinsurance to private ones The ongoing economic crisis leads both governments andprivate bodies to be in demand for better cost optimization leading to a globallybetter governance of the healthcare system[14]

The combination of social and policy factors described in the previous section havealready created the basis for a strong European demand for E-Health services and

applications Based on an analysis undertaken by Capgemini Consulting in the contextof this project the European E-Health market was about at EUR14269 million in2008 year and it is also projected to reach EUR15619 million by 2012 it grows witha rate of 29 A per-country analysis of the results confirms that France GermanyItaly Spain and the United Kingdom are the principal European E-Health marketsHowever the analysis also confirms that over the next three years all nationalE-Health markets will experience some form of growth in this area [15]

With increasing Web users using handheld device to browse Web sites and apps Webdesigners and developers must make sure that their creations look good and workwell on mobile devices just like on traditional desktop computers

Google company predicts that mobile devices will drive travel searches up by 15 -25 in 2013[17]

NASDAQ SCOR has reported that in the United State 51 of smart-phone ownersare using these handheld devices to access travel information[18]

Responsive Web Design has been cited as the No1 web design and developmenttrend for 2013 by the net magazine[19]

It is a real fact that the Smart-phone sales surpassed PC throughout the decade All ofthese are secondary in comparison to the fact that simple and clearly view in handhelddevice is needed to exist in the market of the future The figure 1 below shows thedevelopment of the mobile market

Figure 2 The Development Of Mobile Market[20]

From figure 1 we can draw the conclusion that mobile traffic is increasing incrediblyfast People check their email on mobile device first more and more people wouldlike to use high end and fast systemdevices(it is clear that the user of iPad and iPhoneoccupied the most proportion)

As it is in our E-health model the patient prefer text in large font and input datawithout typing manually A simple and straightforward user interface design issignificant factor for the patient Furthermore specially for the diabetes patientrsquos inour application it can not only help user easier to learn how to use the website torecord their daily indicators but also delight the patients because they donrsquot needzoom the website surface to a proper size

343343343343 ResponsiveResponsiveResponsiveResponsive webwebwebweb designdesigndesigndesignIt is known to us that there are many well-known website organization have launcheddedicated website for iPhone or smart phone For example 3gqqcom mtaobaocomipadxxxcom and so on The question comes that is it necessary for us to designseparate website for each device Certainly it is very complex too many website foreach smart phone

In 2010 Ethan Marcotte wrote an introductory article about the Responsive WebDesign Responsive web design refers to the ability of a web page to respond andadapt to whatever device on which the page is being viewed It aimed at providing anoptimal viewing experience easy reading with the proper resizing panning andscrolling

There are Four principle methods to realize the responsive design when building awebsite the media query view-port fluid grids and flexible images These four arethe key point to realize the responsive web design

1111 MediaMediaMediaMedia queryqueryqueryqueryAs a web designer or front-end developer we all wish that our website can alwayseasily adapt the screen size of the device regardless of whether the user use the21-inch desktop 13-inch laptop or 10-inch iPad or smart phone To design aresponsive web we should use the media queries technique to change the layout ofthe page based on the width of browser and CSS Media query are a bits of CSS in aweb page that can inspect the physical characteristic(ie the width and height of thescreen in pixels ) of the device which request service

We added a few media queries to provide an improved experience on smaller screenslike those on a tablet or smart phone Instead of targeting specific device resolutionswe went with a relatively broad set of breakpoints based on each handheld resolutionsas it shown in the figure 3

Figure 3 Physical pixels on the screen for apple product[22]

Moreover we find that we use different breakpoints also depending on how we viewvarious devices for example portrait and landscape However some browser donrsquotsupport detecting orientation and motion events as it is shown in figure 4

Figure 4 The event of each browser for detecting orientation and motion[23]

Based on the figure3 we choose the most popular browser for apple product IOSSafari 60 and chrome 260 for our testing

Moreover there is another way worth mentioned regarding the responsive web designis that different CSS style sheet can be chosen based on the function characteristic ofthe request deviceltlink href=stylescss type=textcss media=screen rel=stylesheetgtltlink href=printcss type=textcss media=print rel=stylesheetgtThis is an old way which based on the media attribute with such references asmedia=rdquoscreenrdquo or media=rdquoprintrdquo But it canrsquot realize static responsive web design

The media queries allowing us to target styles based on a number of device attributesincluding screen width orientation resolution and so on Media queries allow us totarget not only certain devices and classes of devices but also allows us to actuallyinspect the physical characteristics of the device

2222 View-portView-portView-portView-portThe media query can already do a good job when we adjust the size of the browserbut it does not meet the mobile browserrsquo s requirement this is because the mobileclient browser(iPhoneiPadSafari AndroidChrome) will default the page is designedfor wide-screen so it will shrink the entire page to fit the small screen This indicatedthat just media query technology is inadequate to realize responsive web design thesolution is to combine the media query with Applersquos viewpoint mega tag in the headof the document

ltmeta name=viewport content=gt

There are two ways to type in the content ldquowidth=device-widthrdquo is available but itwill just meet the requirement when the device is portrait but when the device isrotated to landscape the screen will not responsive We use the second method whichset the content attribute value to ldquoinitial-scale=10 maximum-scale=10rdquo the settingof initial-scale=10 means that initializing the page without zooming the effect ofmaximum-scale=10 is to prevent the page zoom in rotation But it also brought amore serious problem preventing the user to manually zoom in or out on the page

3333 FluidFluidFluidFluid gridsgridsgridsgridsWhen design a responsive web Itrsquos your decision to choose between a fixed or fluidgrid to design the layout Throughout this tutorial we are going to focus on thedifference between fluid grids and fixed grids and our selection in responsive design

A fluid is a substance that continually deforms (flows) under an applied shearstress[24] generally web pages are made up of columns and rows Traditionally thisis always done with the use of fixed widths like width 20px Responsive web designmake the size of these pages relative to the screen size rather than a fixed widthWithout setting specific number of pixels wide the container is instructed to occupied25 percent of the width of the screen If different device request service from thewebsite the block will change relatively Fluid grid layout is constructed bypercentage instead of pixel Following is an example of fluid grid

width 90To determine the percentage of the fluid grid you have to calculate the proportionsfor each page element you must divide the target element by its context we cancalculate the extents for each page element with the formula given belowtarget context = result

It is easy to understand this formula with the example ldquobody font normal 100rdquoLet us assume that the font default width size to be 10px we can apply such font-sizeon the formula We have to divide the target value (20px) by the font-size of itscontainer (10px) 20divide10=2

So header h1 is two time of its default body font We can denote it by em then we canput into our CSS style sheet with ldquoh1font-size 2em rdquo(1em is equal to the currentfont size)

While fixed-width layout is constructed by specific pixel measurement This type oflayout is commonly used for web design Following is an example of fixed grid

width 900px

Fixed grid seems more intuitive to set the div width-size with practical value

When selecting which method to be used in our E-health model we take these twointo consideration after reading many articles and discussion we draw a conclusionbased on the E-health situation In reality from the conclusion we get above moreand more people would like to use high end and fast systemdevices( it is clear thatthe user of iPad and iPhone occupied the most proportion) so our E-health Websitewill mainly suitable for the mainstream handhelds such as iPhone and iPad usersWith this precondition four CSS style sheet are enough for our E-health websiteapplication There is no doubt that fluid grid works better than fixed grid but whenapplying fluid grid in the model some shortcomings come out for example whendesign a new web page we should first assign the whole layout of each module forevery handheld device and compute the relative percentage size of the component itwould take much time and energy on the overall design It is indeed that fluid griddisplay perfectly on most of the device but in some specific condition such as whenwe have already arranged an font size proportion and it will change relatively betweenthe scope from 0-300px it also display suitable for the device whose resolution is200px but not perfect because of the deforming image or font-size which will notmeet the userrsquos aesthetic feeling while fixed grids becomes more simple just settingthe practical value will be more convenient and it looks more intuitive Consideringall of these practical situation we combine the fixed grids with fluid grids methodtogether

4444 FlexibleFlexibleFlexibleFlexible imagesimagesimagesimagesWhen a grid scales in size then generally the images and text inside it also need toscale Originally if the actual width of the image is wider than the width of the devicethis will distract the container to slove this problem just the same as fluid gridsimages (or any content in a grid) are instructed to take up a certain percentage of pixelspace relative to the container they are in When the container changes the imagesinside change too Following is an example of flexible images the principle is sameas fluid grids and use the same formula to calculate the percentage too

To design a responsive web page we should use the technologies we have alreadymentioned above Following will be the detail guideline of how to use the responsiveweb design in a E-health application And we will also give a basic frameworkstructure of the responsive UI designing according to the different devices such as the

PC iPad and iPhone

1 In the structure no matter which type of the devices you use firstly we shouldinitialize the page without zooming when the devices is portrait or landscape as thefollowingltmeta name=viewportcontent=initial-scale=10 maximum-scale=10gt

2 Secondly for the different devices the media query has been used for its displayIn the structure four basic ranges for the device width has been defined as thefollowing Default wide-screen styles media all and (max-width 1024px)

styles for narrow desktop browsers and iPad landscape media all and (max-width 768px)

styles for narrower desktop browsers and iPad portrait media all and (max-width 480px)

styles for iPhoneAndroid landscape (and really narrow browser windows) media all and (max-width 320px)

styles for iPhoneAndroid portrait

Then for a screen resolution max width within 1024 pixels we present the page as thePC and iPad landscape originally designed For max width within 768px the page canget the styles for narrower desktop and iPad portrait For max width within 480px thepage can get the styles for mobile phone landscape And for max width within 320pxthe page can get the styles for mobile phone portrait

3 In the structure for different size devices with the same page four basic moduleswith the initial width and height have been defined And at the same time endue allthe style of each module with ldquofloatleft ldquostyle For the PC and iPad (no matterportrait or landscape) each module width will be pre-defined as 50 relative to thewidth of the screen

4 And for mobile phone (no matter portrait or landscape) considering the modulersquospresenting possible smaller if four modules arranged as the PC or iPad so eachmodule width will be pre-defined as 100 relative to the width of the screen asfollowing It will be more suitable for the mobile phone device with smaller screen

5 Once having the basic framework some development workload and time will besaved if a new application can directly and well use this framework In addition the

developer can do some proper modifications according the real requirements of aspecific application For example three modules can be arranged in one row and setthe corresponding width as the fluid grids method has been introduced

From all of the work we have down in the responsive web design we havesummarized up the conclusion and got some personal understanding of thistechnology Firstly Itrsquos worth bearing in mind that therersquos no simple solution tomaking sites responsible on mobile devices Liquid layouts are a great starting pointwe should combine all of the existing technology together rely on the actual conditionMedia queries and the other three are useful ways of adapting your websiteresponsively Secondly remember that there are also a certain number of browsersthat do not currently support the technique and there are some performanceimplications this is the main disadvantage of current responsive web designtechnology Thirdly when applying a responsive web design the key is to test earlyand test often on the handheld device with the Android SDK or iOS Simulator whenthe real devices are not available The last is that many current website have alreadyset the attributes of each element for a few years it would be a huge work to alter allthe component into a relative size it is worth researching in the future to design aresponsive browser which will automatically make the accessible website responsive

Privacy It means that the user can make the decessions by themselves when howand to what personal information is authorized to others [25]

Security It is designed that the personal information can be stored and transmitted ina proper manner limited to the authorized roles which well offers the protection of thedata integrity and availability etc[25]

Through the systematic literature review and internet searching we found that there isa set of national existing standards named HIPAA security rules(Health InsurancePortability and Accountability Act)[26] which is proposed by the US Department ofHealth and Human Services in 2005 to offer administrative technical and physicalstandards to ensure the security of protected health information (PHI) in the E-healthIT system Combining this rules some proper rulesrsquo modification will be done to besuitable for the E-health security framework in our project

452452452452AccessAccessAccessAccess ControlControlControlControl StructureStructureStructureStructureThere are many existing access control models can be used to meet the legalrequirement such as Role-Based Access Control (RBAC) Digital Right Management(DRM) Usage Control (UCON) Mandatory Access Control (MAC) According to thespecific E-health field a systematic comparison will be done to choose a propermodel and make appropriate adjustment to be suited to our frame

RBACRBACRBACRBAC A prospect succedaneum of traditional access control (Autonomic AccessControl Mandatory Access Control) In our model the authorities are directly relatedto roles When a user registered the user can set a role for himself when they becomea member of it users are assigned to corresponding role based on their responsibilityand qualification and the diabetes patients and physicians can access their relatedpage with specify role[29]

DRMDRMDRMDRM Pair of keys was generated including public key and private key The key pairis distributed by a third part called digital authorization center which is trusted byusers Public key is used to encrypt while private key is used to decrypt The messagecan be read only by the private key holder The key pair is generated by the recordcreator[30]

MACMACMACMAC In the MAC model the administrator manages the access control and designthe basic strategy And the other role such as user can not change the rules Once thestrategy is defined the object access authorization has been assigned to a fixedsubjectThough owning a higher security level this kind of access control model ispossible to cause some problems such as the flexible roles authority The other rolescan only follow the strategy the administrator made instead of flexible roleauthorization [31]

UCONUCONUCONUCON The UCON is made up by eight elements subject object and right objectattribute right authentications obligations conditions it is different with traditionalmodel which has not just subject object and right three elements The authority isbased on the attributions of subject and object and authority requirement Accessright can be assigned before or being the access actions Mutable attribute is the mostdifferent quality compared with other access control models Mutable attribute canchange along with the change of access result UCON model includes RBAC MACand DRM Itrsquos a new generation of accessing to control model[32]

Compared with all the access control models UCON is a more potential model forfuture design Itrsquos a new generation of access control model But A UCON basedsystem is more complex than others It not only costs more money but also spendsmore time to design and implement such a system The MACrsquos disadvantage is notflexible access rights are defined for different users this mechanism implies manyadministrative operations At the same time RBAC model is much easier to designthan UCON model It has the attributes of efficient security and flexibility in E-health

system Based on all the advantages and disadvantages of all the model andconsidering the specific characteristic of multiple-roles and user-oriented as thefollowing figure shows

Figure 5 The RBAC model[33]The RBAC is relative suitable for the E-health frame model In our frame the RBACmodel divides all the users into three basic parts Administrator user and doctorAccording the different requirement of each roles we set up the differentcorresponding permissions and actions in the basic frameThe following part willintroduce the different rolesrsquo authorities in detail

Cloud Platform is largely a combination of existing technologies which have alreadybeen around since the early 1990rsquos These technologies include grid computingutility computing and most recently virtualisation It is an emerging computingexample aimed at running the services over the internet flexibility and scalabilityWith the development of cloud platform The advantage has been shown outweigh thedisadvantage

Cloud computing is a framework that make convenient on-demand network access toa shared pool of configurable computing resources enable (for example networksservers storage applications services and so on ) which can be released with minimalmanagement effort or service provider interaction and rapidly supplied and published[34](Peter et al 2009)

Cloud is a combination of hardware and software which are being delivered throughServices There is three service models provided by cloud computing which offerdifferent levels of control and security These level are Infrastructure as a Service(IaaS) Platform as a Service (PaaS) and Software as a Service (SaaS) which are indecreasing order of control and increasing order of security[35]

Cloud Computing can be defined as a service or a platform or an operating systemover the Internet to perform tasks Database has become a part and parcel of life andis being used in almost every computer application As it is considered the most basicthing Cloud Computing also offers this database service There are two differentdatabase now available in our project which is Azure cloud database and MicrosoftSQL server database server Each of them has their own merits and demerits

AzureAzureAzureAzure ccccloudloudloudloud databasedatabasedatabasedatabase the Azure cloud database is typically running on Azure cloudcomputing platform There are two common deployment models the first way is thatusers can run databases on the cloud independently using a virtual machine while thesecond way is that they can also purchase access to a database service managed by acloud database provider [39]

LocalLocalLocalLocal SQLSQLSQLSQL serverserverserverserver databasedatabasedatabasedatabase Microsoft SQL Server is a relational databasemanagement system which is developed by Microsoft As a database it is a softwareproduct whose basic function is to store and retrieve data with requests by othersoftware applications Nowadays there are many different editions of SQL Serveraimed at different audiences and for different usages Its basic query languages areT-SQL and ANSI SQL[40]

In our project when we have already put the website on the cloud there are two waysavailable to store the data one is storing on the cloud and another is storing the data inlocal SQL server we take these two ways into comparison and get the result that theAzure cloud database is better because of four advantage parts the most importantpoint is that the access speed for the website request with the cloud database will bemore faster than the local database when the website has been published on the cloudplatform The second is that it will be flexible and reliable on the cloud platform thethird is that the customer will cost less but own a rapid computation capability andultimated storage The last reason is that we donrsquot need keep the local SQL serveronline all the day but the cloud platform will satisfy the demand at any place and anytime the user can access the website as they like In the E-health website the datastorage will be huge and the situation will also happen that too many users login in therecord it may led to the bottleneck Although it is also feasible with local SQL serverAzure Cloud SQL server appears much more outstanding

The whole E-health application frame applies the BS (BrowserServer) architecturewhich the mainstream web architecture model The web browser is the mostimportant application of the client This model simplify the clientrsquos task and put thecore part of the system functions to the server to largely simplify the systemdevelopment maintenance and use Just install a Browser on the client such asInternet Explorer server install the database such as SQL server The browser datainteraction can be realized with the database through the web server This greatlysimplifies the client computer loads and reduce system maintenance and upgrade costand effortreducing the overall cost of ownership

BS structure of the biggest advantages is that you can doing some operating withoutinstalling any special software in any place as long as there is a computer withinternet access The client almost need none maintenance In case of aboveadvantages of the BS model the whole application will apply it as prior introducedthat the MWA IIS and database has been selected as the server and data storage

Figure 8 Forum pageIn the forum page it offers a public communication platform for all the users sharing

the information and publish the topic they concern about In order to fulfill the pagetwo basic modules Grid-view and Detail view has been selected to use

1Grid-view Grid-view table are used for combining the corresponding data from thedatabase and organize with some format to present the information what the userscare about

2Text-box It is the basic components in web-application The user can put what theywant to publish in the text-box and the content can be store into the correspondingtable in the database through the back-end operation

3Buttons Once fulfilling the text the users can decide whether to send or cancelsending data to server by clicking the Submit button and Cancel button And someactions of the buttons will be done in the back-end programming

4Detail-view Detail-view table is used for view the userrsquos detail information ratherthan the grid-view Once the user want to view a detail information of a record fromthe grid-view it can be easily realized by clicking the Select link Certainlycorresponding data combining will be done

Figure 11 Register and Login in page

The above figures are the register and login interfaces When a new user surf thewebsite he needs register a new unique account for himself which can be used toidentify who is him when he surfs the site again later And the user should offer hise-mail address age and protecting answeretc some basic information which ispossible to be used in password setting and getting back pages Through passwordverification the userrsquos information can be well protected

Figure 12 Change password page

Figure 13 Forget password page

The above two figures are the password setting and forgotten page Through answer

the security question and fulfill the right now password registered before the user canrealize the password changing to improve the password security Whatrsquos more in thepassword forget page the user only needs to answer the security question andusername the password will be sent to the his personal e-mail box automatically

672672672672AuthorityAuthorityAuthorityAuthority managementmanagementmanagementmanagementThis is the model what has been discussed in previous chapter And in this section adetail process will illustrate how to apply the RBAC modelThe below three figuresare the user page doctor page and admin page

Figure 14 Permission page

Through setting three different roles according the RBAC rules the whole websitecan realize the access control and privacy security As you can see in the above figurethe user can access his own personal data collecting and presentation moreover hecan set some specific permissions for the specific user and doctor Only thoseauthority granted information such as glucose diet etc can be viewed by thespecified doctor It well protects the userrsquos privacy data and offer a better mechanismto give the permissions to the doctor and the other user

Figure 15 Doctor page

The above figure is the doctor page the doctor can view some specific information ofthe patient only when the user grants the permission Then the doctor can offer someprofessional advice and the other user having a relationship with the user can observeand take care of the patient

Figure 16 Admin page

The above figure is the administrator page In this page the admin has the permissionto view the user and doctorrsquos detail register information except the password It is a

good measure to protect the user information security without arbitrary changing Inaddition the admin also has the permission to delete a specific user or doctor once heconfirms the user is a malicious or false user Publishing a global notificationpermission is also granted to the admin to give some important notes in the forumplatform

To sum up the above illustration presents the basic applying process with the basicmodel and more security measures can be added in the future work

Figure 19 when the iPhone visit the website

We will give an example of our home page to introduce how to use the frameworkdefined before to realize the responsive web design1 Firstly we should change the header toltmeta name=viewportcontent=initial-scale=10 maximum-scale=10gt2 Secondly we put all the words and image in div container with HTMLprogramming language And enduing all the style of the div with ldquofloatleft ldquostyleIn the application four basic modules has been used But some modifications hasbeen done because the page will has more contents and information so more moduleshave been added into the structure according to the requirement Moreover set all the

element in the div container with flexible size or fixed size as following shows

It contain many images in the div container and give them initiate CSS style likewidth or height3 Thirdly with the help of the media query technology affording another CSS stylewhich has already set breakpoint of the scope for different device And enduringanther CSS style with the flexible and fixed technology like following shows

Page loading time is an important part of providing a responsive user experience andextensive web research suggests that it correlates to how long users will stay on awebsite and how satisfied they are with the interaction It also directly determine thesearch engine ranking of this website[42]

Figure 30 Correlating page load time and user patience Most users will wait only 6to 10 seconds for a site to load [43]

Figure 3 shows the time users are willing to spend on waiting for a web page loadingAccording to surveys conducted by Akamai and Gomezcom there exist 40 percent ofusers will abandon the website if page load time exceeds three seconds And aone-second delay in page response can even reduce conversion by seven percent Themost serious event is that it would led to the economic losses for example ane-commerce site may making $100000 per day a one-second delay would cause $25million loss in annual sales [43]

As page load speed is very important we have to consider about how to improve thespeed the download speed of the network would be considered first according to astudy by PCWorld the average download speed for 3G networks in the US is 2 Mbpsand 62 Mbps for 4G networks A study by Ofcom found that the average downloadspeed for 3G in the UK to be 21 Mbps Outside of North America and Europeconnection speeds are generally slower Because 1 Mbps equals 122 KBs (or 012MBs) this translates into the following244 KBs on average for 3G users (024 MBs)

756 KBs on average for 4G users (076 MBs)[44]However download speed is not the bottleneck The bottleneck is the network latencywhen visiting a website only 20 of the time it takes to display a Web page comesfrom downloading files The rest of the time is spent processing HTTP requests andloading style sheets script files and images So will a responsive web design willimprove the speed of visiting website would it provide a better user experience andeven recoup their economic losses

We separately test our two websites with responsive and no responsive technologywith the chrome browser When testing the speed of these two website we use thepage speed tool comes from google and wwwwebpagetestorg these two tools arevery useful which would generate the report of testing With the help of these reportwe can directly recognize the advantage of responsive web design The figure shownbelow give the detail report of using the same device to detect the website which arewith and without responsive web design The detail report of waterfall view are addedin Enclosure 2

Figure31 The connection view without using the responsive web design

Figure32 The connection view with using the responsive web design

Figure33 The figure show the detail speed of visiting the responsive web

Figure34 The figure show the detail speed of visiting the no responsive web

Result from google page speed toolThe page default got an overall Page Speed Score of 88 (out of 100) (responsivepage)The page default got an overall Page Speed Score of 83 (out of 100) (no responsivepage)

From the figure shown above we can draw the conclusion that the user can get morefaster and simper experience with the responsive website since it is 2 times fasterwhich is 2018s while the non-responsive website get the page load speed of 5349sSpeed is a core feature in website creation responsive web design not only meet thecustomerrsquos requirement and also help the web provider restore the loss

8888 ConclusionConclusionConclusionConclusionThe main purpose of the report is to establish a general E-health web applicationframework including the cloud platform selecting security mechanisms defining andthe usage of the responsive web design technique Through the systematic comparisonthe MWA cloud platform and ASPNet HTML5 CSS3 has been chosen as the maintools due to the well compatibility and operability In addition a general securityguideline common login structure and RBAC access control structure has been givento protect the personal information Moreover four main methods used to realize theresponsive web design have been introduced in the report And a responsive webframework has been designed to offer a basic referenced model for the future specificapplication Finally a prototype web application based on the general framework hasbeen designed and implemented Through testing it proved that the responsive webpage loads more faster than the non-responsive web page

9999 FutureFutureFutureFutureWorkWorkWorkWorkSince the framework and a prototype have been done in the project with in limitedtime there are some ways that we thought can be further improved and implementedin the future work

First of all personal data storage will be a main risk for privacy security especiallythe password encryption in the cloud database Some kinds of encryption measuressuch as RSA and DES etc can be applied to improve the data security level Inaddition communication between client and server needs encryption for avoiding thesniffing

Secondly this prototype just a simple application to show how the framework isapplied so the responsive web design mainly aims to the mainstream handheld device( iPhone and iPad ) in the market Some other type system of the mobile such as theAndroid will be added to well-adapt In addition the mobile UI will be furtherimproved to be more proper and comfortable according the designing peopleacceptable standard

Thirdly considering the inconvenience in remembering many website username andpassword the account combining with some existed account of website and softwaresuch as MSN Facebook etc is necessary It will reduce the userrsquos burden

Lastly since the MS cloud database has been selected as the development part of themodel so the data transfer will be further researched and implemented in case theowner of the website want to change the database vender Huge amount of datatransfer will be a big problem in the future if this situation will happen

The purpose of all these works aims to provide user a pleasuring experience and greatuser interaction Technology changes the life so learning new technique constantly isquite necessary and important
