The world is growing and fruiting with the help of technological conceptual advancements. These improvements in technology, has brought a change that all the sectors now use to serve with modern facilities and maintain the best coordination among these facilities. The introduction of medical software like EMR and EHR is the advancement in medical sector which coordinates with the areas of clinical decision making, drug prescribing etc. The clinical decision making, and drug and treatment prescribing are the first hand uses of EHR data. But there are some alternate uses of EHR data also. We better can say it to be the re-use of EHR data. Mostly in case of clinical and other drug related researches and studies the reuse of EHR/EMR data is incorporated. A clinical research is geared by the need to provide reliable data to support safety and efficacy. And the data from EHR lays the foundation for the reliability of the data from a clinical research which is to be used in furtherance. Data retrieved from medical software systems like EHR should be of such a quality that it improves the efficiency of patient care. This quality concern should not be there only from the point of first use of EHR data but also from the re-uses of data mostly by researchers to support healthcare. But the re-use of EHR data must be treated with caution, because the data protection issue is always pertained to reuse of data like the EHR data. So, we need a system that can help us in achieving a proper balance in between the protection of data in one hand and more optimized reuse of data on the other.

The use and re-use of EHR data in the healthcare information segment is always accompanied by various drawbacks. These drawbacks accompanying re-use of data vary from lack of legal and technical standards to uniformity of use. We need proper standards and protocols of data collection and the re-use. Only a properly collected piece of information whether primary or secondary can help in achieving research objectives. The re-use of data, generated by a medical software be it an EHR or any other record keeping system, should be cost-effective. Clinical experiments or trials done with re-use of EHR data is a cost effective way than collecting the data afresh. The uniformity in approach in re-use of data from medical software (EHR) is another point of concern in our discussion. The present situation in health care requires researches to carry out research studies in isolated fashion at different locations. The use of the EHR which is the common medical software in use varies widely across different nations worldwide and so challenges the re-use of EHR data in clinical researches and other uses. Other issues like the maintenance of patient confidentiality, requirement of time and cost effective resources are a few to requiring attention in the field of re-use of EHR data. A qualitative control on re-use of EHR data can lead to a sustainable, beneficial and commercial impact on treatment and drug development which ultimately will lead to better healthcare system in a viable economy.

With the increased focus on HIT (Health Information Technology), the situations in US and EU in re-use of EHR data is changing positively. Introduction of HITECH act in US is an initiative in the direction of Health Information Technology. The European Seventh Framework Program for research and technological development is the initiative by EU to focus on HIT. The use of proper EHR systems in place is growing fast in US. The vision of the EFPIA EHR task force is another forcing factor that will help in attaining the standards for re-use of EHR data.

And in future with such a huge amount of efforts we surely will have a proper system with proper medical software in place which will coordinate in re-use of EHR or any such data with satisfaction.

2 Imaging the medical business: DICOM

The efficiency in every sphere of life due to the technological and scientific advancements includes the health sector also. With the technological and scientific progress the people are becoming more aware of their health and nutrition. And due to this growing importance on health, the medical sector is also experiencing a huge growth. This growth in the medical sector is accompanied by the technological improvements as in the cases of other sectors. Almost all the hospitals and clinics are using technological advancements in their practices. Be it the medical software for billing or the EMR software system they are using. It is estimated that the use of an appropriate medical software product in place has the potential to increase the earnings by a considerable amount of more than or equal to 30%. So, simply you cannot neglect the importance that a right medical software product bears in medical industry.

And in this age of advancement any medical business unit without the imaging division is just incomplete. Imaging in medical business is of a great importance that nobody can ignore and even alter. The image reports like cardiographs, biomagnetic imaging, computer radiography, tomography, diaphanographs, microscopy, endoscopy, mammography, spectroscopy, radio fluoroscopy, thermographs, ultra sound, x-ray angiography are a few of the imaging services to name that comes into the scene when we talk about medical imaging reports. Today’s treatment of a patient is incomplete if no one of these images accompanies his records. And with these imaging services there is a common standard for the handling, storage, printing and transmission of imaged information in medical imaging. This common standard or the common format for the images is known as DICOM.

DICOM is the abbreviation for Digital Imaging and Communications in Medicine. The Picture Archiving and Communication System or simply PACS which is a system, uses this standard for the all the medical imaging. DICOM includes a file format definition and a network communication protocol. And this network communication protocol uses TCP/IP for communication in between the systems. DICOM enables the integration of scanners, printers, workstations, computer systems and other network hardware into PACS. DICOM supportive devices come with the capacity to support different DICOM classes separately. DICOM is developed by American College of Radiology (ACR) and National Electrical Manufacturers Association (NEMA). The present DICOM is the third version of this standard. The first version was released in the year 1985. It was ACR/NEMA 300. The second version came in the year 1988 by the name ACR/NEMA V2.0.

DICOM bears some very necessary information along with the images like the patient ID, which is inseparable from this information even by mistake. While handling DICOM data different medical software products are used. Software tools for the transfer, organizing of DICOM data, for image supports etc. are very widely used. Trial Wire is a very useful medical software used in DICOM data transfer, de-identify and handling. There are other software products like GDCM, OsiriX, ImageVis3D, VRRender, ImageJ, MicroDicom, Medstrat, kPacs, UniPACS etc. which are very commonly used in DICOM interpretation.

Trial Wire is a medical software product used to transfer DICOM image from one to another web enabled computer.  It is a java based tool available free of cost. The use of a medical software product like Trial Wire reduces the cost associated with the couriers used to transfer DICOM data from one location to the other. Trial Wire also provides an audit trail for any changes made to the DICOM data in order to comply with the HIPAA regulations.

3 Medical Software in HIS sphere:

Automated health practice management systems, e-prescribing, CAT scanners, heart rate monitoring with software are a few of the names from the medical area in the 21st technology driven century. From the patient’s personal data to the cardiographs everything has got the driving force of technological advancement. Introduction of PACS or Picture Archiving and Communication System and DICOM or Digital Imaging and Communication in Medicine has changed the way of imaging in the medical practices. Similarly the introduction of EMR/EHR medical software has changed the way of medical record keeping. In most of the hospitals and clinics in EU, US or Canada you would notice the use of medical software like an EMR system in practice very well. Likewise the introduction of medical software for billing purpose is another important contribution of modern technology. Medical billing software used in billing has introduced the comfort of coordination among other medical services like lab report of patients and its coordination with proper insurance claims etc.

Medical Software is the modern technological term that has driven the medical sector to an unalterable stage of advancement. The introduction of various medical software products has changed the way of management and even the administration concerned with hospitals and clinics across EU and US. Medical software use even in health informatics like HIS is of great help. HIS or Hospital Information System is the platform covering all the medical related clinical as well as administrative sections. From the simple hospital discipline management to the management of health records, financial records, and other medical reports all are covered under this single umbrella named HIS.

Hospital Information System or simply HIS is the information system assisting all the administrative, financial and clinical aspects of a hospital or a clinic. HIS also known as CIS or Clinical Information System comprises of a comprehensive, integrated information system covering all the papered and non-papered software based clinical as well as administrative medical areas of concern. A simple HIS construction can be understood as the sphere covering the entire medical aspects from EMR systems to the software based billing services. A proper HIS is always aimed at achieving best possible support towards the health care of patients and an adequate management by deploying either medical software products or machineries along with responsible technicians/persons. Radiology information system, Laboratory Information System, PACS, etc. are the sub categories of Hospital Information System. EMR, EHR, software based billing services, insurance claims, patient care, profit drive, hospital management, administrative works all belong to the sphere of HIS.

The advantage from HIS includes well maintained decision support system in healthcare, exchange of information towards the betterment of the healthcare services, coordinating the standards of ancillary services with the primary one, enabling referring physicians and doctors to access all the studies and reports via a single user interface etc. In a nut shell a proper HIS with adequate medical software support is the demand of the time, conforming to which can rise your business in the medical sector to an incredible level.

People may not know what the silo effect actually means. But everything is simple. The silo is the situation when somebody’s opinion, idea and plan are limited by the existing prejudices and experience of other people.

The employees of software testing company, as well as the specialists of other companies not connected with IT sphere, perform their duties in silos. This is rather complicated notion, and it should be regarded more precisely.

What Are the Silo Types?

• A formal silo. In every company, there are the groups of specialists which perform particular tasks and solve the defined problems. There are developers, testers, product managers, sales managers, administrators, etc.
• An informal silo. This type concerns the same ideas, standards and concepts shared by the particular groups or schools. Moreover, the silo effect may also be regarded in terms of applying of definite testing principles and approaches, for example, the session approach or the automation principle.

The silo effect has both advantages and disadvantages. Hereafter, the benefits of the silo effect in software testing field will be regarded.

What Are the Advantages of Silos?

• It is the basis of building the team of specialists which share the common view. It is easier to form the team of like-minded specialists.
• Silos provide the consolidation of efforts of every member of the test team.
• The support networks are established with the help of silos.
• Silos encourage the effective communication within the test group.
• The credibility for every member of the group is established due to silos.

All mentioned aspects of silos have the positive influence on the testing process and the team spirit. Unfortunately, despite regarded pluses, the silo effect has some minuses. It is very important to prevent the negative effects of silos.

What Are the Disadvantages of the Silo?

• The silo may limit the expert’s imagination. The tunnel vision of the checking process does not provide the effective functional testing or performance testing.
• The silo causes the tribalism. The enmity to developers or another test team prevents the well-timed production of the bug free application or system.
• Miscommunication, misconceptions, troubles and difficulties may be arisen by the silo.
• The rejection of every idea or conception which differs from your own thoughts leads to less productive automated testing or any other checking type. The valid propositions should be reviewed and taken into account.
• The specialists may become blind to risks because of the silo effect.

There is a fine line between the silos benefits and disadvantages. One should always control the degree of silo influence on every team member and the whole test group.

In the world today there are tons of web hosts out there offering “web hosting unlimited bandwidth” but what’s the catch? In a lot of the cases these companies are tricking the users by including terms in their TOS that say things along the lines of “If we decide that you are using more then the unlimited bandwidth web hosting we sold you we will terminate your account for no reason. It is important to ALWAYS read a companies TOS to see if they will terminate your account without notice. All web hosts have some policies that say if you use too many resources where other user’s accounts are put in jeopardy you can be suspended. This is common practice and is not frowned upon, it the web hosts that purposefully mislead their clients into thinking they are getting unlimited, and then suspending when that client uploads too many files. There are several steps that you can take to ensure you don’t get burned.

Read the Web Hosting Unlimited Bandwidth Policy!

It is very important that yo read whatever policy the company has in place on web hosting unlimited bandwidth. You not only need to read it once, but reading it multiple times and becoming very familiar with it is a good idea, that way if the company you are dealing with decides to contact you, you always have the ability to turn the tables on them by knowing your rights and enacting them. You would be surprised how many hosting client’s do not even know the rules by which their hosting policies are covered.

Ask Questions BEFORE you buy

If you have read my other articles then you already know the steps that need to be taken in order to find an Inexpensive Web Host. From this article you should have learned to only deal with companies that have direct forms of contact such as live chat and telephone communication. Contact the “Web Hosting Unlimited Bandwidth” Provider ask them the important questions like. “Do you suspend accounts without notice” and “What are your resource usage limits” asking these types of questions will help ensure you know what you are a signing up for.

Use your money back guarantee!

The majority of web hosts today have various forms of money back guarantees that you can take advantage of within the first 30 or 60 days of hosting. If you are just reading this article and find out you are with a dishonest host, simply take advantage of your money back guarantee and use your new found knowledge to go get legitimet and honest web hosting unlimited bandwidth.

Cloud Computing, Next wave in Computing: Upcoming Trend in Industry

Cloud computing is Internet (cloud) based development and use of computer technology.

Cloud Computing is an emerging computing technology that uses the internet and central remote servers to maintain data and applications. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. This technology allows for much more efficient computing by centralizing storage, memory, processing and bandwidth. Cloud computing is broken down into three segments: “applications,” “platforms,” and “infrastructure.” Each segment serves a different purpose and offers different products for businesses and individuals around the world.

Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends IT’s existing capabilities.

In June 2009, a study conducted by Version One found that 41% of senior IT professionals actually don’t know what cloud computing is and two-thirds of senior finance professionals are confused by the concept, highlighting the young nature of the technology. In Sept 2009, an Aberdeen Group study found that disciplined companies achieved on average an 18% reduction in their IT budget from cloud computing and a 16% reduction in data center power costs.

Depending on who you are talking to, you will see different perceptions about what Cloud Computing actually is, from the simplest web-hosted solutions right through to virtualized processing environments with Web-Service initiated provisioning and decommissioning.

The main challenges for Cloud Computing before it is likely to enjoy wide-spread adoption are the following:

• Persistence & Availability – The ability to continue working during outages or the ability to mitigate outages.
• Privacy and National Security Concerns – The hosting of information outside of your country’s borders does concern Public Sector organizations. The US Patriot Act for example is a concern for some countries in adopting cloud services. It is thought that Country-silted Clouds may be able to address this.
• Geo-Political Information Management Concerns – The Political risk a country takes on by housing information for another country.

Cloud Computing is all about:

1. SaaS (Software as a Service)

These type of cloud computing delivers a single application through the browser to thousands of customers using a multitenant architecture. On the customer side, it means no upfront investment in servers or software licensing; on the provider side, with just one app to maintain, costs are low compared to conventional hosting.

2. Utility computing

The idea is not new, but this form of cloud computing is getting new life from Amazon.com, Sun, IBM, and others who now offer storage and virtual servers that IT can access on demand. Early enterprise adopters mainly use utility computing for supplemental, non-mission-critical needs, but one day, they may replace parts of the datacenter. Other providers offer solutions that help IT create virtual datacenters from commodity servers, such as 3Tera’s AppLogic and Cohesive Flexible Technologies’ Elastic Server on Demand. Liquid Computing LiquidQ offers similar capabilities, enabling IT to stitch together memory, I/O, storage, and computational capacity as a virtualized resource pool available over the network.

3. Web services in the cloud

Closely related to SaaS, Web service providers offer APIs that enable developers to exploit functionality over the Internet, rather than delivering full-blown applications. They range from providers offering discrete business services to the full range of APIs and even conventional credit card processing services.

4. Platform as a service

Another SaaS variation, this form of cloud computing delivers development environments as a service. You build your own applications that run on the provider’s infrastructure and are delivered to your users via the Internet from the provider’s servers.

5. MSP (managed service providers)

One of the oldest forms of cloud computing, a managed service is basically an application exposed to IT rather than to end-users, such as a virus scanning service for e-mail or an application monitoring service (which Mercury, among others, provides). Managed security services delivered by Secure Works, IBM, and Verizon fall into this category, as do such cloud-based anti-spam services as Postini, recently acquired by Google. Other offerings include desktop management services, such as those offered by Center Beam or Ever dream.

6. Service commerce platforms

A hybrid of SaaS and MSP, this cloud computing service offers a service hub that users interact with. They’re most common in trading environments, such as expense management systems that allow users to order travel or secretarial services from a common platform that then coordinates the service delivery and pricing within the specifications set by the user. Think of it as an automated service bureau. Well-known examples include Rearden Commerce and Ariba.

7. Internet integration

The integration of cloud-based services is in its early days. OpSource, which mainly concerns itself with serving SaaS providers, recently introduced the OpSource Services Bus, which employs in-the-cloud integration technology from a little startup called Boomi. SaaS provider Workday recently acquired another player in this space, CapeClear, an ESB (enterprise service bus) provider that was edging toward b-to-b integration. Way ahead of its time, Grand Central — which wanted to be a universal “bus in the cloud” to connect SaaS providers and provide integrated solutions to customers — flamed out in 2005.

Citrix Cloud Center

C3 is designed to give cloud providers a complete set of service delivery infrastructure building blocks for hosting, managing and delivering cloud-based computing services. C3 includes a reference architecture that combines the individual capabilities of several Citrix product lines to offer a powerful, dynamic, secure and highly available service-based infrastructure ideally suited to large-scale, on-demand delivery of both IT infrastructure and application services. This architecture consists of four key components:

• Platform – Powered by Citrix XenServerTM Cloud Edition:  The new XenServer Cloud Edition is a powerful virtual infrastructure solution optimized for service provider environments. It combines the cloud-proven scalability of the Xen® hypervisor which powers most of the world’s largest clouds, with all the virtualization management and dynamic workload provisioning capabilities of the full Citrix XenServer product line ( see separate announcement on XenServer 5), enabling cloud providers to host and manage any combination of Windows® and Linux environments. XenServer Cloud Edition also features an innovative consumption based pricing model to meet the needs of service providers that charge their customers based on metered resource use.
• Delivery – Powered by Citrix® NetScaler’s®:  Through its rich policy-based AppExpert engine, Citrix NetScaler’s delivers cloud-based resources to users over the Web, continually optimizing user application performance and security by dynamically scaling the number of virtual machines (VMs) or servers available in response to changing workload demands and infrastructure availability. This allows cloud providers to balance workloads across large distributed cloud environments and transparently redirect traffic to alternate capacity on or off premise in the event of network failures or datacenter outages.  NetScaler’s can also dramatically reduce server requirements in large cloud centers by offloading protocol and transaction processing from backend server pools. NetScaler’s proven architecture is designed for highly scalable, multi-tenant Web applications and delivers Web services to an estimated 75 percent of all Internet users each day.
• Bridge – Powered by Citrix WANScaler:  As larger enterprises begin experimenting with cloud-based services for parts of their own infrastructure and application hosting strategy, cloud providers will also need reliable and secure ways to provide a seamless bridge between hosted cloud services and premise-based enterprise services. Over time, C3 will incorporate a set of open interfaces that allow customers to easily move virtual machines and application resources into a cloud-based datacenter and back again as needed. WANScaler technology will play a critical role in this enterprise bridge by accelerating and optimizing application traffic between the cloud and the enterprise datacenter, even over long distances.
• Orchestration – Powered by Citrix Workflow Studio TM: Tying it all together, Citrix Workflow Studio provides a powerful orchestration and workflow capability that allows the products in the C3 portfolio to be dynamically controlled and automated, and integrated with customer business and IT policy. Workflow Studio allows customers to control their infrastructure dynamically–integrating previously disconnected processes and products into a single powerful, orchestrated and cohesive system. This unique capability will make it easier for cloud providers to enable highly efficient burst able clouds that automatically scale resources up and down based on demand, shifting hardware resources to where they are most needed and powering them down for maximum power savings when not needed.

Today, with such cloud-based interconnection seldom in evidence, cloud computing might be more accurately described as “sky computing,” with many isolated clouds of services which IT customers must plug into individually. On the other hand, as virtualization and SOA permeate the enterprise, the idea of loosely coupled services running on an agile, scalable infrastructure should eventually make every enterprise a node in the cloud. It’s a long-running trend with a far-out horizon. But among big megatrends, cloud computing is the hardest one to argue with in the long term.

We have all been there. You are minding your own business, browsing around on your computer. Suddenly your computer freezes up. The Windows blue screen (aka blue screen of death or BSOD) brings up a list of blue screen errors and your computer crashes. Because this happens at random times, it can be pain when your computer restarts and whatever you were doing was not saved.

Now there are a few things that can cause blue screen errors. If you had been running ten different programs at once then that could be a cause. Your computer’s RAM can only handle so many programs running at once. But if the blue screen errors happen semi-frequently even when your are not running a ton of programs, then there is probably a problem in your Windows registry.

The Windows registry is the most important folder in your computer. It contains sensitive information that runs all software and hardware. And unfortunately the directory cannot clean itself and is very often filled with useless and corruptible information.

This is where registry repair software comes in. The first time you use registry cleaner software you may be shocked by all the fatal errors in your registry you had no idea about. I know I was the first time.

If you clean up registry errors you can significantly reduce the blue screen errors. Don’t let the windows blue screen of death ruin your computer’s performance. With a simple free scan below you can fix registry problems and get rid of those blue screen errors for good. Give it a try!

Besides software testing, testers have a lot of different activities such as meetings, calls, e-mails, etc. It is necessary to distinguish testing procedure itself from other actions. Session-based test management helps to solve this problem.

Session is the separated scope of work done during testing procedure. Each session has its own purpose and problem that should be solved. If the session lasts less than 45 min, it is called a short session. A long session takes about two hours.

What Are the Main Session Tasks? 

• Test design and its execution. The product is examined, and tester looks for any problems. 
• Bug searching and reporting. If the problem is found, tester makes sure that it really is a bug and makes the necessary reports.
• Session setup. Tester configures tools, writes reports, reads documentation, etc.

These activities are often called the ‘TBS’ metrics. It is the basis of testing procedure. Every testing type, for example, system testing, functional testing, load testing, etc., contains such tasks. 

Tester should estimate the approximate time needed for each of these tasks including time spent on opportunity. Opportunity testing contains the tests that are out of the session charter. If tester notices the serious off-charter problem, he should focus on this particular problem diverting from the charter.

What Are the Key Elements of the Session Sheet?  

• Bugs (show the product quality).
• Issues (problems related to testing procedure).
• Notes (contain the ideas of test cases, function and risk lists, etc.).

There is a certain structure of the session report. It should contain some obligatory points.

What Are the Components of the Session Report?

• Session charter (including goal setting)
• Tester’s name
• Date and time of the beginning
• TBS metrics
• Data
• Issues
• Bugs found
• Notes

Each of these points should be checked. With the help of the tool written in Perl, the session sheet is scanned. The results of scanning are shown in the form of table that can be easily analyzed and formatted. It is the ToDo session sheet or the so-called the ‘hopper’ list. After checking some issues with the help of functional testing, the specialist fills the table and starts to perform another testing type, for example, usability testing. It provides the execution of testing procedure step-by-step without missing anything.

Moreover, the hopper helps to cooperate with clients and perform their different requests. Testers make an appropriate note in the hopper. They mark the request with the priority defined by the client.

The search utility is intended to make the use of session sheet more convenient. It enables to display and print any part of the session sheet.
