6.0 Introduction
6.1 General Introduction
The human immunodeficiency virus (HIV) infection, which can cause acquired
immunodeficiency syndrome (AIDS), has shown a high degree of prevalence in
populations all over the world. According to the World Health Organization (WHO)
reports, it shows that about 33.4 Million people were living with HIV/ AIDS in the
world where 22.4 Million were from Sub-Saharan Africa to December 2008 (WHO
AIDS epidemic update, 2009).
Knowledge of HIV status has always had the potential for benefiting an individuals
health and wellbeing and for helping to prevent the further transmission of HIV.
Knowledge of HIV status has been especially beneficial when it has enabled people to
access care, support and treatment, in the form of psychosocial support; home based
care; nutritional support; palliative care; treatment for opportunistic infections,
tuberculosis and sexually transmitted infections; and antiretroviral therapy (WHO,
2002).
Knowing HIV/ AIDS status is only possible if an individual undertakes HIV/ AIDS
testing, which is initiated by voluntarily counseling which prepares the individual to be
ready willingly to undergo the testing and know his or her status.
HIV testing has also been problematic in the context of clinical care. This is because, in
many places, HIV testing has reportedly either not been conducted at all as part of
clinical care or has been conducted without consent, confidentiality, counseling, the
provision of results or any follow-up care to benefit health. Even in places where people
with AIDS occupy more than 50% of hospital beds, almost none of these people have
2
8/2/2019 Proposal Draft 2 Completed
3/22
been diagnosed as HIV positive or told that they have AIDS. Although this
phenomenon may result from fear that these patients will face discrimination or be
denied health insurance, etc., if they are diagnosed as having AIDS, it also appears to be
a form of medical denial that ultimately does not serve the best interests of these people
or their families or communities (WHO, 2002).
The aim of this study is to investigate the current procedures of voluntarily and
counseling for HIV/AIDS, also to investigate how the existing information technology
is utilized to support Counseling and testing for HIV/AIDS. From this investigation a
new strategy will be suggested on the utilization of information technology to improve
the access to information and the counseling and testing of HIV/AIDS. After suggesting
the new strategies, an online HIV/AIDS counseling system for TAWG will be
developed, implemented and tested in order to cover all gapes that face to face
counseling is facing.
6.2 Statement of the Problem
Online counseling provides an alternative to traditional face-to-face counseling at a
time when traditional methods are inaccessible, inconvenient, or not preferred. Online
counseling may be a useful alternative for people, unable to make it to a counselors
office, live in a remote area, have a disability, limited time constraints, or would like to
get an idea of how counseling works before seeing a counselor face to face.
Knowledge of HIV infection is necessary to access many forms of HIV-related support,
care and treatment. As drugs become more affordable and political commitment and
financial resources in support of access rise, greater access to care and treatment,
including antiretroviral therapy, is becoming much more of a real possibility.
Programmes are in place to increase the access to antiretroviral drugs in general and in
3
8/2/2019 Proposal Draft 2 Completed
4/22
particular, to prevent mother-to-child transmission. Further, where treatment, care and
support have become more widely available; stigma and discrimination, which have
always been disincentives to HIV testing, have reportedly decreased.
Given that the changing landscape of the HIV/AIDS epidemic has resulted in new
opportunities as well as new imperatives to increase knowledge of HIV status, there is a
need to explore approaches to delivering HIV testing and counseling services.
6.3 Objectives of the Research
6.3.1 General objective
The objective of the study is to investigate the current procedures of voluntarily and
counseling for HIV/AIDS, also to investigate how the existing information technology
is utilized to support Counseling and testing for HIV/AIDS.
6.3.2 Specific Objectives
To study the operations of the normal counseling services for HIV/ AIDS
To propose ICT based techniques for counseling services for HIV/ AIDS
To implement the proposed techniques by building a online virtual counseling
services for HIV/ AIDS for Tanga AIDS Working Group (TAWG)
6.4 Research Questions
The following are some research questions that will be answered by this study:-
What are the existing problems facing face to face counseling system for
HIV/AIDS
What are the problems facing online counseling services
4
8/2/2019 Proposal Draft 2 Completed
5/22
How can ICT be used to enhance/ facilitate counseling services for HIV/ AIDS
6.5 Significance of the study
This research will address the importance of using Information and Communication
tools as one of the way to improve access to information relating to HIV/ AIDS. Hence
encourage people to attend the newly designed voluntarily counseling and testing for
HIV/ AID since most people are avoiding to visit counseling and test due to forbear of
people to think that there are affected since these services will be available anywhere
6.6 Literature Review
6.6.1 Information about TAWG
The Tanga AIDS Working Group (TAWG) is an innovative non-governmental
organization in Tanzania dedicated to caring for people with AIDS and reducing the
spread of HIV. The main Objectives of TAWG is: -(http://www.tawg.net/Services.php)
To provide home-based care and support to people living with AIDS and their
families.
To collaborate with traditional practitioners.
To prevent the spread of HIV / AIDS through community-based education
Programmes.
To provide guidance and assistance to other organizations working on Aids
6.6.2 AIDS Counseling services in Tanzania (Limitations faced)
Provisions of HIV/AIDS counseling services in Tanzania started in 1988. In 2001,
ANGAZA Program received a grant from USAID to enhance counseling and testing
services in the country. However, Tanzania indicator survey of 2003-2004 indicated
that 15% of people aged 15 to 49 years tested HIV. A national HIV testing campaign
5
8/2/2019 Proposal Draft 2 Completed
6/22
was realized as one of the approaches for scaling up counseling and testing services as
entry to HIV prevention, care and support services. ANGAZA Program supported
launch of campaign in mid July 2007 and scaling up the campaign in the country.
The number of VCT sites has increased considerably during 2003 2007
implementation period. There were 1,027 VCT sites by the end of 2006, compared to
289 in 2003. This number includes sites in health facilities and stand alone sites. The
geographic distribution of VCT sites is still inequitable, with an urban bias, although all
districts have at least 4 sites. The number of clients counseled and tested has increased
to 680,520 in 2006, up from about 140,000 in 2003. (NMSF, 2007)
Despite this considerable roll-out of service availability, the uptake of VCT in the
country is still quite low. According to the Tanzania HIV/AIDS Indicators Survey
(THIS) 2003/04, only about 15% of men and women are reported to have ever
undertaken an HIV test. Women and men living in urban areas are two to three times
more likely to have been tested than those in rural areas. One of the reasons for the low
uptake is related to limited access to VCT services, particularly in the rural areas. Low
public awareness about the benefits of knowing ones HIV status, insufficient human
resources with skills in counseling and fear of stigma are also barriers to increased VCT
utilization and the lack of care and support after HIV testing. The recent National
voluntary HIV testing campaign aims at increasing the number of Tanzanian who know
their HIV status and thus to take action to protect themselves and others
6.6.3 Computer Technology as a tool to improve Social Services
It is a good time to consider the power of current technological advances. Increasingly,
communication and information technologies have become part of our everyday lives.
6
8/2/2019 Proposal Draft 2 Completed
7/22
The use of computers is increasing day by day, because they are used in many fields to
make our lives easier (Bayhan, Olgun, & Yelland, 2002). Computers can present crucial
information and offer effective tutorial (An instructional book or program that takes the
user through a prescribed sequence of steps in order to learn a product) instruction
(Cammarata, 2006). Computers also connect us with other people, store vast amounts of
data, and provide us with access and entertainment (Yelland, 2002).
6.6.4 Computer Technology in Education and Learning
Computer technology has important transformative effects on society (Logan, 1995). It
provides concrete experiences, helps children control the learning experience (Papert,
1998), and supports children's development in all domains, as they use computers to
investigate questions, solve problems, explore, and manipulate objects on a screen
(Dodge, Colker, & Heroman, 2003). For example, children can use computers to
investigate questions by using a program that teaches number concepts. Such a program
might allow children to create "monsters," for example, by adding the right number of
body parts. Also, children can explore with computers, using software programs that
label vocabulary with pictures, written words, and spoken words. Such software
programs often verbally identify an object when the child clicks on it. Some software
programs allow children to match pictures of images to their beginning letters (Dodge
et al., 2003).
Approaches to the use of ICT in education are presented within the context of education
for a multidisciplinary human services workforce. A range of approaches are
considered predominantly using a blended approach of ICT and face to face delivery.
These include creating and sustaining community in a virtual environment to develop
inter-professional skills. A focus of skill development is on reflective practices using
7
8/2/2019 Proposal Draft 2 Completed
8/22
online role-plays and group work principles and processes in virtual situated learning
environments. Issues for professional practice cultures in the online environment are
considered within a global context (Martin, Jennifer & Hawkins, and Linette).
6.6.5 Computer Technology in Health
Information and communication technologies have changed the face of the world we
live in. ICT enables people to communicate with family, friends and colleagues around
the world instantaneously, gain access to global libraries, information resources, and
numerous other opportunities. ICT may also bring an improvement in health care
delivery systems. So, we may define Information and Communication Technology as
one of the driving forces of globalization ICT encompasses the broad spectrum of
communication technologies from radio, film, television, press, and telephone along
with more participatory forms such as theatre, video or storytelling. It also focuses on
the electronic end of the spectrum such as e-mail, the Internet, mobile phones and
digital video.
The science and practice of health or medical informatics changed radically in the late
1970s and early 1980s when computer use began to become increasingly common in
healthcare environments (Shortliffe & Blois 2006). Since then, improvements in the
speed and processing power of computers, computer networks, and the Internet has led
to increased accessibility and availability of information for healthcare professionals to
support their decision-making processes (Vimarlund et al 2008; Rose 2005; Winkelman
& Leonard 2004; Chamorro 2001). According to Hassett (2002): A health information
system (HIS) encompasses a wide array of applications and information systems that
are linked or interfaced. A HIS supports the provision of care to patients and the
business aspects of the healthcare organization by communicating information. It is
now hard to imagine healthcare without information and communication technology
(ICT) based applications for both the accumulation and interchange of clinical
8
8/2/2019 Proposal Draft 2 Completed
9/22
information (Ammenwerth et al. 2004). This is in part because ICT-based applications
have been recognized as enablers. This means that they are tools that offer solutions to
the problem of the increasing accumulation of patient data (Timpka et al 2007;
Andersen et al. 1994; Friedman 1996). Due to their central role in enabling ubiquitous
access to information, ICTbased systems ensure a more efficient use of healthcare
organizations scarce resources (Harrison et al. 2007; Rahimi et al 2008; Pardes et al.
2006).
6.6.6 Trust Management in online counseling services
For the Internet it is necessary to establish a foundation of trust among the participants,
in order to be accepted as a viable platform, where the big companies can migrate their
current desktop software applications. Trust is often mentioned in the context of e-
commerce and has been developed over time through the formation of appropriate
policies, procedures and practices to safeguard transactions and company assets
(Furnell, M. S et al, 1999). The objective of security should be to manage risks by
anticipating what is probably going to happen and limiting the risk exposures that could
injure an organization's reputation. Perfect security is hard to achieve, infinitely
expensive and often not a rational goal (Singhoi, A, 2000)

6.6.8.3 Ask the internet therapist services
Have therapists who are committed to working with people who are interested in
improving their overall mental health, reducing anxiety, and enhancing relationship
skills. Our online counselors are skilled in the areas of relationship counseling, love
addiction, codependence, stress, assertiveness, dysfunctional family counseling, and
chemical dependence counseling. We are confident that we can assist you in making the
connection with your loved ones more rewarding and meaningful.
(http://www.asktheinternettherapist.com/healthcare_medical_clinic_services.asp)
6.6.8.4 ICT based HIV/AIDS education
ICT-based HIV/AIDS education and counselling services have been developed in
various African countries, such as Uganda and Tanzania [Bloome 2001; Duveskoq
2008]. The existing e-learning approaches for HIV/AIDS education provide limited
10
8/2/2019 Proposal Draft 2 Completed
11/22
educational services to children with most solutions presenting static online content,
carton-based stories and social networks using email as a means of communication
[Bada and Suhonen 2008]. There is need to have a conceptual and pedagogical design
of e-learning environment, which is aimed to provide a fresh perspective to the
HIV/AIDS education and counselling services for Tanzanian. The design of TAWG
online counselling service will provide the way forward to have an application that can
cover all needed areas for Tanzanians.
6.6.9 Different Approaches to Systems Development
Systems Development
Systems analysis is all about getting a detailed understanding of information relating to
a proposed system collected previously (Avison and Shah, 1997).
The phases of systems development are feasibility study, analysis, design,
implementation, testing and maintenance .These phases of project development are the
standard phases used more or less in all texts on systems analysis and software
engineering. It is generally referred to as theLinear Life Cycle (Pressman, 1992).
Alternative methods of Systems Development:
There have been many criticisms of the Linear Life Cycle. Thus, the Linear Life Cycle
is looked on as way too simplified for the complexities of the real world. The following
are some of the alternatives available to the simple Linear Life Cycle model.
Prototyping
Gerri (1999) define a Prototyping as the process of building a model of a system. In
terms of an information system, prototypes are employed to help system designers build
11
8/2/2019 Proposal Draft 2 Completed
12/22
an information system that intuitive and easy to manipulate for end users. Prototyping is
an iterative process that is part of the analysis phase of the cycle (Gerri, 1999).
With prototyping the user feedback gained from developing a physical system that the
users can touch and see facilitates an evaluative response that the analyst can employ to
modify existing requirements as well as developing new ones (Gerri,1999).
There are number of the advantages of the prototyping but some of them are reduced
time of system development and decreases of cost in development process. Prototyping
results in higher user satisfaction and expose developers to potential future system
requirement (Gerri, 1999).
The negative side of the prototyping includes the dangerous of the system being left in
insufficient analysis. According to (Gerri, 1999) argues that now there is widespread
use of prototypes of its advantage of inherently increase the quality and amount of
communication between the developer/analyst and the end user.
A Spiral Model
This model aims to combine the best elements of the Linear Life Cycle and Prototyping
but adding the new element of risk analysis (Pressman, 1992).
Object Orientation (OO)
Object orientated systems development requires the developer to think in terms of
objects and object classes (Avison and Shah, 1997). This means that every attribute of a
system is modeled just like it is in reality.
7.0 Materials and Methods
7.1 The study area
The study areas for this case will be Tanga AIDS Working Group (TAWG).
12
8/2/2019 Proposal Draft 2 Completed
13/22
7.2 Methods
The following are techniques which will be used in the analyze of the current
system of the flow and processing of information on HIV/ AIDS Counseling
services Accurate information about HIV/ AIDS.
7.2.1 Primary source of data.
Observation
The observation will be made on how the face to face voluntarily counseling for
HIV/AIDS is conducted how it can be modeled to cover distance counseling
services.
Interview
The general questions will be asked from client that will help in collecting the user
requirements. Most of prepared questions are open-end question in order to explore as
much as information from the client. To analyze the data collected from open-end
questions, qualitative analysis methods will be used where data will be examined and
compared. The meaningfulness of the data will be determined by established goals and
objectives of the research.
7.2.2 Using a secondary source of Data
The review of the literature from previous research on how other countries
process their online counseling services will be conducted. Other document for
HIV/AIDS counseling services will be reviewed.
7.2.3 Software requirement analysis
This will involve the following activities; develop the understanding of the
application domain and Interact with the stakeholders in the system like Ministry
13
8/2/2019 Proposal Draft 2 Completed
14/22
of Health and Social welfare, Tanga region Medical Officer, Counselors and the
community as whole to know their requirements.
7.3 Materials
On designing the system, MySQL DBMS will be used to implement the database
schema, the PHP scripting language for creation of the user interface and link to
database. Apache will be used as a web server. The reason for choosing the above
tool is because they are open source. (i.e. free to use)
7.4 System Testing
The unit test will be done first and after integration of different units, the whole
system will be also tested. The system testing will be conducted to identify the
correctness, completeness, security and quality of developed computer software.
Testing will be performed on behalf of the stakeholders that are intended to reveal
quality related information about the product with the respect to the context in
which it is intended to operate.
7.5 Software architecture
The architecture of a software system refers to an abstract representation of that
system. Researcher will produce one or more 'models' of what he see a system
eventually look like, with ideas from the specification section either used or discarded.
A document will be produced with a description of the system, but nothing is specific
(Pressman, 2000).
The figure below shows us the overview system architecture. It depicts all important
parts of the system from the user (counselee) to the counselor.
