This document presents a model for an online fuzzy-logic knowledge warehousing and mining system for diagnosing and treating HIV/AIDS. The system would store patient data and medical knowledge about HIV/AIDS. It uses fuzzy logic and data mining to predict HIV/AIDS status, monitor patient health over time, and determine recommended treatment plans. The system was tested on real patient data from a hospital in Nigeria. It aims to provide an efficient way to diagnose, treat, and monitor people living with HIV/AIDS.
Adaptive Learning Expert System for Diagnosis and Management of Viral Hepatitisgerogepatton
Viral hepatitis is the regularly found health problem throughout the world among other easily transmitted diseases, such as tuberculosis, human immune virus, malaria and so on. Among all hepatitis viruses, the uppermost numbers of deaths are result from the long-lasting hepatitis C infection or long-lasting hepatitis B. In order to develop this system, the knowledge is acquired using both structured and semi-structured interviews from internists of St.Paul Hospital. Once the knowledge is acquired, it is modeled and represented using rule based reasoning techniques. Both forward and backward chaining is used to infer the rules and provide appropriate advices in the developed expert system. For the purpose of developing the prototype expert system SWI-prolog editor also used. The proposed system has the ability to adapt with dynamic knowledge by generalizing rules and discover new rules through learning the newly arrived knowledge from domain experts adaptively without any help from the knowledge engineer

SPATIAL CLUSTERING AND ANALYSIS ON HEPATITIS C VIRUS INFECTIONS IN EGYPT IJDKP
Lots of studies worldwide have been carried out to check out the prevalence of Hepatitis C Virus (HCV) in human populations. Spatial data analysis and clustering detection is a vital process in HCV monitoring to discover the area of high risk and to help involved decision makers to draw hypotheses about the cause of disease. Egypt is declared as one of the countries having the highest prevalence rate of HCV worldwide. The anomaly of the HCV infection’s distribution in Egypt allowed several researches to identify the reasons that contributed to such widespread of HCV in this country. One way that can help in identification of areas with highest diseases is to give a detailed knowledge about the geographical distribution of HCV in Egypt. To achieve that goal, Data mining analytical tools integrated with GIS can help to visualize the distribution. Thus, the main propose of this paper is to present a spatial distribution of HCV in Egypt using case data obtained from the Egyptian health institute National Hepatology Tropical Medicine Research Institute (NHTMR). The visualization of the spatial analysis distribution by means of GIS allows us to investigate statistical results that are easily interpreted by non-experts.

Although numerous disease intelligence and surveillance systems exist, they are plagued with inaccurate or untimely data. We contend, furthermore, that it was this lack of data quality – and not
the lack of surveillance systems or networks – that prevented the global community from acting earlier in response to the Ebola outbreak in 2014–2016. The new field of ‘connected diagnostics’ is one solution to this concern, as it automates data collection directly from the diagnostic instruments to multiple levels of stakeholders for real-time decision-making and policy response.
This article details how the intervention of ‘connected diagnostics’ could solve the primary underlying failure in existing surveillance systems – the lack of accurate and timely data – to enable
difficult political decisions earlier. The use of connectivity solutions can enable critical health and operational data to empower the Africa CDC, regional hubs, and each country with a consistent
and automated data feed while still maintaining country privacy and controls.
A study on “impact of artificial intelligence in covid19 diagnosis”Dr. C.V. Suresh Babu
Although the lungs are one of the most vital organs in the body, they are vulnerable to infection and injury. COVID-19 has put the entire world in an unprecedented difficult situation, bringing life to a halt and claiming thousands of lives all across the world. Medical imaging, such as X-rays and computed tomography (CT), is essential in the global fight against COVID-19, and newly emerging artificial intelligence (AI) technologies are boosting the power of imaging tools and assisting medical specialists. AI can improve job efficiency by precisely identifying infections in X-ray and CT images and allowing further measurement. We focus on the integration of AI with X-ray and CT, both of which are routinely used in frontline hospitals, to reflect the most recent progress in medical imaging and radiology combating COVID-19.
A PROPOSED NEURO-FUZZY MODEL FOR ADULT ASTHMA DISEASE DIAGNOSIScscpconf
The task of medical diagnosis with the help different intelligent system techniques is always crucial because it require high level of accuracy and less time consumption in decision making.
Among all other AI techniques Artificial Neural Networks (ANN) as a tool for medical diagnosis has become the most popular in last few decades due to its flexibility and accuracy. ANN was
developed after getting the inspiration from biological neurons. There are various diseases that are still needed to be diagnosed. Among many other critical diseases like cancer, thyroid disorder, diabetes, heart diseases, neuro diseases, asthma disease was also tried to bediagnosed
effectively with various ANN mechanisms by different researchers. Due to various uncertainties about symptoms the study of Neuro-Fuzzy technique in this context became very popular in last few years. Neuro-Fuzzy now-a-days is one of the most advanced technique that is mainly concatenation of two model-neural networks and the fuzzy logic. In this model various
parameters are used that are much crucial if ill-chosen and may led to failure of the whole system. Recent trend in analysis is following this model for advanced expert work. In this study
an enhanced Neuro-fuzzy model has been proposed for the proper diagnosis of adult Asthma disease and to foster the proper aid or medication to the patients and make physicians alert forthe upcoming disease pattern otherwise they may lack in the process of providing improper medication at right time. In the first phase data collected from various hospitals are used to
train by three different types of learning of ANN like ANN with Self Organizing Maps (SOM),ANN with Learning Vector Quantization (LVQ) and ANN with Backpropagation Algorithm
(BPA) through NF tool for much accurate result. In the second phase fuzzy rule base is appliedto the classified data for the diagnosis of the disease.
A Survey and Analysis on Classification and Regression Data Mining Techniques...theijes
Classification and regression as data mining techniques for predicting the diseases outbreak has been permitted in the health institutions which have relative opportunities for conducting the treatment of diseases. But there is a need to develop a strong model for predicting disease outbreak in datasets based in various countries by filling the existing data mining technique gaps where the majority of models are relaying on single data mining techniques which their accuracies in prediction are not maximized for achieving expected results and also prediction are still few. This paper presents a survey and analysis for existing techniques on both classification and regression models techniques that have been applied for diseases outbreak prediction in datasets.

Abstract We propose an integrated semantic web framework
consisting of formal ontologies, web services, a reasoner and a
rule engine that together recommend appropriate level of
patient-care based on the defined semantic rules and guide-
lines. The classification of healthcare-associated infections
within the HAIKU (Hospital Acquired Infections – Knowl-
edge in Use) framework enables hospitals to consistently fol-
low the standards along with their routine clinical practice and
diagnosis coding to improve quality of care and patient safety.
The HAI ontology (HAIO) groups over thousands of codes
into a consistent hierarchy of concepts, along with relation-
ships and axioms to capture knowledge on hospital-associated
infections and complications with focus on the big four types,
surgical site infections (SSIs), catheter-associated urinary tract
infection (CAUTI); hospital-acquired pneumonia, and blood
stream infection. By employing statistical inferencing in our
study we use a set of heuristics to define the rule axioms to
improve the SSI case detection. We also demonstrate how the
occurrence of an SSI is identified using semantic e-triggers.
The e-triggers will be used to improve our risk assessment of
post-operative surgical site infections (SSIs) for patients un-
dergoing certain type of surgeries (e.g., coronary artery bypass
graft surgery (CABG)).

Introduction
Healthcare-associated Infections (HAIs) affect millions of
patients around the world, killing hundreds of thousands
and imposing, directly or indirectly, a significant socio-
economic burden on healthcare systems [1]. According
to the Centers for Disease Control (CDC) [2], hospital-
acquired infections in the U.S., where the point preva-
lence of HAIs among hospitalized patients is 4 %, result
in an estimated 1.7 million infections, which lead to as
many as 99,000 deaths and cost up to $45 billion annually
[3, 4]. Similar or higher rates of HAI occur in other coun-
tries as well with an estimated 10.5 % of patients in Ca-
nadian hospitals having an HAI [5]. Clinical assessment
and laboratory testing are generally used to detect and
confirm an infection, identify its origin, and determine
appropriate infection control methods to stop the infection
from spreading within a healthcare institution. Failure to
monitor, and detect HAI in timely manner can delay di-
agnosis, leading to complications (e.g., sepsis), and

Epidemic Alert System: A Web-based Grassroots ModelIJECEIAES
Most web-based disease surveillance systems that give epidemic alerts are based on very large and unstructured data from various news sources, social media and online queries that are parsed by complex algorithms. This has the tendency to generate results that are so diverse and non-specific. When considered along with the fact that there are no existing standards for mining and analyzing data from the internet, the results or decisions reached based on internet sources have been classified as low-quality. This paper proposes a web-based grassroots epidemic alert system that is based on data collected specifically from primary health centers, hospitals and registered laboratories. It takes a more traditional approach to indicator-based disease surveillance as a step towards standardizing web-based disease surveillance. It makes use of a threshold value that is based on the third quartile (75 th percentile) to determine the need to trigger the alarm for the onset of an epidemic. It also includes, for deeper analysis, demographic information.
Evaluation factors contributing to the treatment default by tuberculosis pati...PUBLISHERJOURNAL
Tuberculosis (TB) is one of the biggest public health problem and now ranks alongside Human Immunodeficiency Virus (HIV) as the world’s leading infectious cause of death. Globally, patient compliance with anti-TB therapy estimated as low as 40% in developing countries, remains the principle cause of treatment failure. The aim of this study was to establish the factors contributing to treatment default by Tuberculosis patients at ART clinic in Ishaka Adventist Hospital, Bushenyi District. A cross-sectional and descriptive study which employed both qualitative and quantitative approach of data collection were used. The study was conducted in ART clinic at Ishaka Adventist Hospital, Bushenyi District and it took a period of four weeks. A purposive sampling technique was used to select the study participants. Results showed that out of 38 study participants, majority 26 (68%) were of age 30 years and above. A large proportion 24 (63%) of the participants were unemployed compared to the least 14 (37%) who were employed. Majority 21 (55%) travel at a distance of 10km and above to get TB treatment. Out of 38 participants, majority 26 (68%) did not informed the family or friends when they were on TB treatment. Of 26 participants 16 (61.5%) had fear of being isolated and 2 (7.7%) were other reason of no support. A large proportion of participants rated the attitude of staff who attended to them at the health facility to be unfriendly with 21 (55%) while very few 6 (16%) were rude. The ministry should ensure availability of and access to resources for strengthening systems for delivery of quality tuberculosis treatment, prevention and control.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

ABSTRACT
The need for a reliable and efficient way of storing and mining data about people living with HIV/AIDs
with the intent to monitor the health status for effective therapy is on the increase. This paper presents a
model of a web-based system for knowledge warehousing and mining of diagnosis and therapy of
HIV/AIDs using Fuzzy Logic and data mining approach. A model was developed, using the predictive
modeling technique, for predicting HIV/AIDs and monitoring of patient health status. The fuzzy inference
rule and a decision support system based on cognitive filtering was employed to determine the possible
course of action to be taken. A case study of some data of PLWH was used and the result obtained shows
that the developed system is efficient. The system uses XAMP on Windows OS platform. The system was
tested and evaluated with satisfactory results.

1. INTRODUCTION
Medical diagnosis is the ability to form valuable opinions and make good decisions about the
condition of a patient, while therapy is the administration of drugs to patients. The major problem
in the medical field is the diagnosis of disease which is due to human error [1]. In [2] a medical
diagnosis involves the state space search of medical knowledge of a particular disease, patient
history, patient examination and drug. Medical diagnosis and therapy involves the determination
of the nature of a disease from observation of signs and symptoms and subsequent curative
treatment of such a disease. These are the work of a medical expert (Physicians) who possesses a
wealth of knowledge in the field. According to [3], the African AIDS epidemic continues to pose
severe public health and developmental challenges for many African nations. A primary
impediment in the fight against AIDS is lack of information and communication about the
disease. Information and Communications Technology (ICT) hold vast potential to hinder the
spread of the disease, as well as key elements of all aspects of HIV/AIDS strategies, including
prevention, treatment, care and protection to human rights. In [3], the role of information and
communications in the fight against AIDS in the African continent. It is intended to increase
2. International Journal of Computational Science and Information Technology (IJCSITY) Vol.1, No.3, August 2013
28
understanding of how information and communication can offer key resources in relation to
HIV/AIDS, and to suggest key actions information and communications can take to assist in
combating HIV/AIDS.
In [4], it is observed one of the many challenges of access to treatment through anti-retroviral
medication is the difficulty of receiving accurate and up-to-date information at the planning level.
It was noted that Information and Communication Technology (ICT) has been used in a number
of pilot studies to address this bottleneck, by providing an infrastructure for telemedicine and e-
health applications. It was also suggested that Anti-Retroviral Treatment (ART) delivery to poor
communities can be significantly improved by integrating local primary health-care information
with centralized databases to allow national monitoring.
In [5], a framework for the interventions to close the digital divide in AIDS care was developed.
It describes the development and pilot testing of a workshop-style intervention designed to close
the digital divide in AIDS care. [6], evaluated the efficacy of LifeWindows, a theory-based,
computer-administered antiretroviral (ARV) therapy adherence support intervention, delivered to
HIV plus patients at routine clinical care visits. In that study, 594 HIV plus adults receiving HIV
care at five clinics were randomized to intervention or control arms. The result indicated that
intervention versus control impact in the intent-to-treat sample - including participant who’s
ARVs had been entirely discontinued, who infrequently attended care, or infrequently used Life
Windows - did not reach significance. Intervention impact in the On Protocol sample (328
intervention and control arm participants whose ARVs were not discontinued, who attended care
and were exposed to Life Windows regularly) was significant. On Protocol intervention various
control participants achieved significantly higher levels of perfect 3-day ACTG-assessed
adherence over time, with sensitivity analyses maintaining this effect down to 70% adherence.
That study supports the utility of Life Windows and illustrates that patients on ARVs who persist
in care at clinical care sites can benefit from adherence promotion software.
A software engine for the mining and processing, periodic update of the knowledge warehouse
and statistical analysis of findings was developed in [7] for NITDA on its intervention in capacity
building for Nigerian tertiary institutions and by extension the education sector of Nigeria
economy. Infection with HIV is now endemic in several African countries; estimates of the
number of infected people is in millions. Zero prevalence rates of HIV infection vary from less
than 1% up to 20% of the general adult population, and from 27% to 88% of female prostitutes in
the cities of Central and East Africa. It is evident that, in many parts of the continent, HIV
infection has created a major public health problem, which may have reached the same scale as
malaria, diarrhea, respiratory diseases, and malnutrition. In one major hospital in Central Africa,
up to 35% of the children and adults admitted having were HIV infection, and this figure is likely
to increase. Thus, many African clinicians are taking care of HIV-infected patients, and they will
be confronted with an increasing number of AIDS cases in the near future.
A fuzzy rule-based framework for the management of tropical diseases with main focus on
malaria is presented in [8]. The system involves fuzzzification, inference and defuzzification. The
system is able to diagnose malaria case as either mild, moderate, several or very several. The
symptoms and signs of the diseases were fuzzified. With the help of fuzzy rules developed and
the assistance of some medical personnel, the fuzzified variables were composed, inferred and
later defuzzified to give final diagnosis. [9], implemented an evidence based medicine principles
via a computerized clinical decision support system (CDSSs). In [10] a model of asynchronous
collaboration between people with very different knowledge of medicine in which a computer
framework attempts to mediate between patients and physicians to help reduce some of the
differences in communication was designed.

[11], developed a medical consultation system, CADIAG-4, for general internal medicine, which
is intended to assist the differential diagnostic process by indicating all possible diseases which
might be the cause of patient’s pathological findings, with special emphasis on rare diseases. It
uses the formal framework of fuzzy set theory and fuzzy logic to represent the uncertainty in
medicine. In [12], a fuzzy expert system for heart disease diagnosis was designed. The system has
13 input fields, one output field and rule base. The mamdani inference method – fuzzy expert
system designing, membership function, fuzzy rule base, fuzzification and defuzzification
methods were used. [13], focused on the use of ICT to design a web-based fuzzy expert system
for the management of hypertension using the fuzzy logic method. In the study, systolic blood
pressure, diastolic blood pressure, age and Body Mass Index (BMI) were taken as input
parameters to the fuzzy expert system and hypertension risk as output parameter. The resultant
hypertension risk was based on fuzzy rules that were developed for the expert system. The
defuzzification method was Root Sum Square.
This paper attempts to develop a fuzzy-logic, knowledge warehouse and mining model for
HIV/AIDs diagnosis, therapy and preventive measure. Data were sourced from the University of
Benin Teaching Hospital.
2. SIGNS, SYMPTOMS AND CLASSIFICATION OF HIV/AIDS
According to [14], AIDS in an adult is defined by the existence of at least two major signs
associated with at least one minor sign, in the absence of known causes on immunosuppression
such as cancer, severe malnutrition or other recognized etiologies. However, the presence of
generalized Kaposi sarcoma or cryptococcal meningitis is sufficient by itself for the diagnosis of
AIDS. The major signs are:
a. Weight loss ≤ 10% of body weight
b. Chronic diarrhea (for more than 1 month)
c. Prolonged fever (for more than 1 month) (intermittent of constant)
The minor signs are:
a. Persistent cough (for more than 1 month)
b. Generalized pruritic dermatitis
c. Recurrent zoster
d. Oropharyngeal Candidiasis
e. Chronic progressive and disseminated herpes virus infection
f. Generalized lymphadenopathy
[14] and [15], it is opined that epidemiological studies have demonstrated that HIV has three
major modes of transmission: sexual, parenteral, and perinatal. No evidence exists to support any
other routes of transmission, including through food, water, vectors, or casual contact. HIV has
been identified in the whole blood, serum, tears, saliva, cerebrospinal fluid, brain tissue, urine,
semen, breast milk, amniotic fluid, and vaginal/cervical secretions. However, the low titre of virus
and infrequency of virus isolation from most of these fluids suggest that with the exception of
blood, serum, semen, cervical/vaginal secretions, and breast milk, they play an insignificant role
in HIV transmission.
In the National Guideline for HIV and AIDS Treatment and Care in Adolescent as reported in
[16], diagnosis of HIV infection is based on the demonstration of antibody in plasma or serum,
and of virus in the blood. The virus can be demonstrated in the blood with nucleic acid-based tests
4. International Journal of Computational Science and Information Technology (IJCSITY) Vol.1, No.3, August 2013

(PCR for proviral DNA and RT-PCR for plasma viral RNA), culture and p24 antigen assay. With
the technology that is available at present, HIV antibodies are detectable within four to six weeks
of infection, and within 24 weeks in virtually all affected individuals. However, virus can be
detected in plasma at least one week earlier. This period of absent antibody in the presence of
virus in plasma is called the “window period”.
Antiretroviral Therapy has the following components:
a. Pre-treatment Evaluation includes:
i. Complete history and physical examination (always think of Pregnancy,
Anaemia, Hepatitis and TB)
ii. Clinically and Immunological classification of the patient
iii. Check Laboratory results (FBC with differential, ALT, Creatinine, CD4+ cell
count, pregnancy test)
iv. Evaluation of nutritional and psychosocial status
v. Assessment of readiness for therapy
vi. Development of patient-specific adherence strategy
b. Criteria for ART
Initiation of therapy depends on CD4+ cell count and WHO clinical staging:
i. WHO Stage IV disease irrespective of CD4+ cell count
ii. WHO Stage III disease with CD4+ cell counts < 350/mm3
iii. WHO Stage I or II disease with CD4+ cell counts < 200/mm3
iv. Any WHO Stage with CD4+ cell count 200-350 mm3
– consider for therapy
c. Counseling for ART
There are many patients who know their HIV sero-status through VCT and other testing
services but are yet to consider starting ART. However, when a decision is reached to
commence ART, additional counseling is required to address the following issues:
i. ARVs do not offer a cure. HIV may be suppressed but is not eradicated from the
body
ii. Use of ARVs is associated with impaired quality of life and long term survival
iii. ARVs need to be taken daily for life to prevent development of resistance and
treatment failure
v. ARVs, like other medications, are associated with side effects
vi. Better results are obtained with good adherence to the treatment regime
vii. Some patients may fail to respond to treatment and may required changes in their
treatment regime [16]
A Data Warehouse is a subject-oriented, integrated, time-variant and non-volatile collection of
relational/ multidimensional database optimized for decision support which is separated from the
database [17], [18], [19]. It is an information repository in which components (knowledge
components) are cataloged and stored for reuse [20], and has logical structures to store knowledge
that are analogous to the system tables that implement data storage in the data warehouse [21].
The architecture of the knowledge warehouse and mining of diagnosis and therapy of HIV/AIDS
consists of the Knowledge base, Database model, Weighted Averaging Method, Fuzzy logic,
Inference engine, Decision Support Engine, Cognitive filter and Emotional filter as presented in
[7].

A three tier web based system which has the following elements is proposed:
a. Client-Tier: Provides a Graphical User Interface (GUI) to the end-users, which is
achieved using a web browser, such as Internet Explorer, built using HTML with PHP.
b. Web-Tier: Provides the dynamic content to users; presents the data model to clients;
accepts and analyze user inputs; presents users input to ES for processing and forwards
responses back to user.
c. Database: Stores the object data and handles system logic. It deals with systems rules
and data.
The database model considered for the proposed system employs an object-oriented approach and
is viewed as a network of semantically related structured and unstructured knowledge of the
HIV/AIDS and its diagnosis. Relational database modeling technology is adopted [22]. The
general form of a relation is given by:
R[ai, ai+1, ai+2, ai+3, ai+4 , …, an-1, an,]
Where R represents the name of the relation, the set {ai}, i = 1, 2… n, represents the attributes,
properties and decision variables of R. The database is composed of nine relations and some
presented below
Patient [patientNo, patientName, PatientAddr, patientAge, patientSex, Nationality, MaritalStatus,
BloodGroup, NameAddrofNextofKin
Signs [PatientNo, diseaseID, description-of-sign]
Symptoms [PatientNo, symptomID, description-of disease]

LabTest [date, patientNo, description-of-lab-test]
HIVDIAGNOSIS [patientNo, Diag-No, Diag-Log]

The activities of the user on the database are described as transaction. A transaction may be
classified as an update or query type:
a. Update Transactions: The update transactions are the activities that are responsible for
the insertion of new records, modification of existing records and deletion of unwanted
records in the database. Update transactions on any database may be carried out by the
Database Administrator (DBA) or some other privileged users. The DBA will be
responsible for the initial creation of the database and modification of the database from
time to time to reflect the current state exhibited in real life. The database is the visual
image of real life of HIV/AIDS and diagnosis of the disease. The database should,
therefore, constantly exhibit the true position of current trends and real life possibilities in
HIV/AIDS and the diagnosis of the disease, to maintain integrity and credibility. The
security and confidentiality of the database can be guaranteed if appropriate right of
human expert access and update database is adequately provided, controlled and
monitored. In this study, the right of privileged users to access and update database is
provided, monitored at the following three levels: Insertion of new records, Modification
of old records, Deletion of unwanted (see Figure 2.1)
b. Query Transaction: query transactions are activities that are responsible for questioning
the database and generate useful reports. In practice, query transactions are carried out on
a database by any authorized user of the database in the category. Database expert users,
Database end user, database casual users.
In order to create the security of the database and the confidentiality of the transactions
carried out on it, each category of users is provided with the appropriate right into the

database. In the web based system proposed in this study, only the first two access levels
are defined because all end users can query the database and also perform update
transaction if they are interested.

2.1 Data Warehouse and Mining
This stage involves the conception, acquisition, cleaning and loading of data into the data
warehouse. Specifically, patient’s record was collected from the Introviral Human Virology,
Nigeria (IHVN), U.B.T.H. The data was carefully analyzed. The analysis involves demographics,
study results, problems, therapies, allergies, subjective and physical findings, and encounter
summaries. The data warehouse was created on a centralized server dedicated to fielding data
mining queries. The clinical data was mapped from data structure into relational tables in the
personal computer environment. MySQL was chosen as the Database Engine installed into the
Computer System. For the purpose of this study, a few sample dataset from the data warehouse
was created that was mined for knowledge discovery. Multiple SQL queries were run on the data
warehouse to create the dataset. As each variable is added to the dataset, it is cleansed of
erroneous values, data inconsistencies and formatting discrepancies.
In this study, the predictive model was used to mine the data. The predictive models use data with
known results to develop a model used to explicitly predict values for different data [23]. For
example, a model can be built using the payment history of people to whom you have given loans
to help identify people who are likely to default on loans. The model in this study was built from
the patients’ history which helped to identify the various classes and ranges of infections about
patients. Using the Classification models requires you to identify those characteristics of cases
that indicate to which group each case belongs. This pattern can be used both to understand the
existing data and to predict how new instances will behave. The Data mining creates
classification models by examining already classified data (cases) and inductively finding the
predictive pattern. In some data mining problems, an expert classifies a sample of the database
and this classification is used to create the model which will be applied to the entire database.
2.2 Fuzzy Logic for Diagnosis of HIV/AIDS
The logic of the diagnosis and therapy of HIV/AIDS involves the following phases: Fuzzification,
Fuzzy Inference (Fuzzy Rules) and Defuzzification. Fuzzy logic requires knowledge in order to
reason. The knowledge is provided by the expert who knows the process and stores it in the fuzzy
system. The knowledge repository for HIV/AIDS contains both the qualitative and quantitative
decision variables. These variables are used in the fuzzification, inference, and defuzzification as
discussed in the following sections.
Fuzzy Rule Base
The rule base is defined according to expert’s experience. As used in this research work, Figure
2.2 describes the action to be taken given the states of the inputs variables. Fuzzy logic offers a
possibility to update the knowledge base continuously [24] and by this, previous diagnosis is
improved. After proposition (rules), the next phase is to perform defuzzification in order to
evaluate the crisp output.
The fuzzy logic analysis and control method involves:
a. Receiving of one, a large number, of measurement or assessment of conditions existing in
some system we wish to analyze.
b. Processing all these inputs according to human based, fuzzy "If-Then" rules, which can
be expressed in plain language words, in combination with traditional non-fuzzy
processing.

c. Averaging and weighting the resulting outputs from all the individual rules into one
single output decision or signal which decides what to do or tells a controlled system
what to do.
The output signal eventually arrived at is a precise appearing, defuzzified, "crisp" value. Fuzzy
Logic Control/Analysis Method diagram is shown in Figure 2.2.

Defuzzification is the process of producing a quantifiable result in fuzzy logic, given fuzzy sets
and corresponding membership degrees. Defuzzification is interpreting the membership degrees
of the fuzzy sets into a specific decision or real value. In this study, the center of gravity (centroid
method) is used for defuzzification given in equation (1):
…………………………………………………………….. (1)
where: xi represent the ith. symptoms, k is the number of items in the fuzzy set and y is the crisp
value.
The average is probably the easiest and the most widespread solution to aggregate information.
The average is defined as the single value which all the individuals of a population should have so
that their total is unchanged. When the sample contains several times the same individuals, it is
possible to reformulate the average as a weighted average by introducing coefficients related to
each individual. So a weighted average is an average in which a weight, wi, is assigned to each
quantity xi to be averaged. The weights determine the relative importance of each quantity on the
average [25].
A physical interview session with some medical doctors working closely with patients living with
the disease was carried out to gather information about the various symptoms of the disease so as
to enable the construction of the analytical membership function shown below. Some of the
diseases are measured by days, weeks or months to ascertain the level of severity, while some are
measured in degrees centigrade. Also some of these symptoms are quantitative while others are
qualitative in nature. Each symptom has its membership function constructed and represents its
degree of severity denoted with letter “X”. Using set theory, the symptoms are represented as:
{X | X is a set of symptoms}

HIV/AIDS risk is shown in Table 1. The membership function of negative and positive are
trapezoidal and membership function of Indeterminate is triangular. In this study, the
indeterminate fuzzy set explains the inability to detect the AIDS virus because the patient is in his
‘window period’, so a retest is advised after 3 months. The window period is the period of absent
antibody in the presence of virus in plasma [16].

Fuzzy logic resembles human decision making process which allows the use of approximate data
to find precise solution. It allows one to express knowledge with subjective concepts as “very
severe”, “severe”, and “mild” which are mapped into exact numeric ranges which can be
described as the membership function of a fuzzy set for the classification of pattern. For each
quantitative and qualitative variable which do not allow for a precise outcome, a psychometric
scale is drawn to measure its total solution space which is bounded by the smallest value to the
largest allowable value. Given a solution space for the attribute of “HIV/AIDS risk” using a
psychometric scale defined within the range of 1 to 10. This attribute could be broken down to
three fuzzy sets “Negative”, “Indeterminate”, “Positive”. The fuzzy sets are not necessarily
symmetric because the ranges of values they cover are not necessarily equal but always
overlapping to some degree. This is because a value may be a member of more than one set. The
inference procedure employs the averaging method of drawing inference. In this procedure, each
function is clipped at the average and the "fuzzy" centroid of the composite area is computed.
Most of the therapies are qualitative in form, thus they form fuzzy and linguistic variables. The
quantitative variables of the drug therapy can be transformed to fuzzy and linguistic variables
taking the minimum and maximum quantity of drugs prescribed by the system. The CD4+ T-Cell
count helps to monitor disease progression and ART therapy. In this study, the patient’s histories
are mined to determine the stages of the HIV/AIDS treatment that should be and therefore the
drugs regimen are prescribed according the Doctors prescription.
The Antiretroviral Therapies include the following:
a. Pre-treatment Evaluation
b. Initiation of ART: Initiation of therapy depends on CD4+ T-Cell count and WHO clinical
staging.
c. Counseling for ART
These issues should be thoroughly discussed by the Counselor or any health worker who is
directly involved with the patient. They should also do follow-up visits whenever the opportunity
arises [16]. Thus, there is a very dynamic situation in HIV-infected people involving continuous
viral replication and destruction and replacement of CD4+ T cells. While the CD4+ T-cells count
is a less expansion and less technical measure of HIV disease progression, quantifying the viral
load is currently the most direct measurement of the HIV disease process. It has also been used to
assess the risk of disease progression and the response to antiretroviral therapy (ART). As the
disease progresses, CD4+ T-cell count declines but may rebound if therapy is efficacious;
however, this parameter alone is an incomplete marker for clinical assessment of a patient.
Nevertheless, in resource poor settings (which include a large proportion of the most affected
11. International Journal of Computational Science and Information Technology (IJCSITY) Vol.1, No.3, August 2013

countries), the CD4+ T- cell count is a more affordable and hence more practical yardstick for
monitoring disease progression and ART efficacy [16]. The CD4+ T-cell count in table 1 shows
the various stages of HIV disease progression:

There are four classes currently available for treatment based on the site and mechanism of action.
Other classes are at various stages of development but are not yet widely available for clinical
use. Different classes and their mechanisms of actions:
a. Non-nucleoside Reverse Transcriptase Inhibitor (NNRTIs)
b. Nucleoside Reverse Transcriptase Inhibitor (NRTIs)
c. Nucleotide Reverse Transcriptase Inhibitor (NtRTIs)
d. Protease Inhibitors (PIs)
Some of the new classes include the Entry Inhibitors which prevent the virus from gaining access
into the cytoplasm of the T-cell. There are categories of these inhibitors:
a. The Chemokine receptors antagonists
b. Attachment inhibitors
c. Fusion inhibitors
According to the [16], it is recommended that combinations of drugs from at least two different
classes be used so that drugs can act on at least two different points in the HIV life cycle.
Monotherapy or dual therapy is not recommended for treatment as the risks of resistance
development are greater. The more the number of sites on the life cycle of the virus the drugs act,
the less the likelihood of development of drug resistance. A minimum of drug including an
NNRTI or a PI is typically used. Based on availability, efficacy and ease of administration, the
following are recommended:

The Decision Support System module is used to fine-tune and filter results from the data mining
engine. This consists of two sub-components namely:
a. The Cognitive Filter: this sub-module helps to analyze the alternative output reports of
the Data Mining engine using the objective analyses presented to it by the Data
Warehouse, and
b. The Emotional Filter: helps to analyze the output reports of the Cognitive filter on the
basis of the subjective feelings of the Data Warehouse.
The Decision Support System also helps to construct the unstructured information which have
been passed to the data mining engine and have been processed via a “Keyword Analysis” to
determine the degree of relevance to the search query. Also, text analytics technique which is a
process of text mining is used to construct relevant data from unstructured information. When the
results have been adequately filtered by the Decision Support System, they are passed to the user
through an Interface. The end of the DSS is the User Interface which allows the user to interact
with the system by specifying a data mining query or task, providing information about processes
and data warehouse schemas or data structures, evaluate alternative patterns of the data mining,
and visualize the patterns in different forms like tables, Cross Tabs, graphs etc.
3. CONCLUSION
HIV/AIDS is one of the greatest health pandemic in the world over. The social, moral, economic,
psychological and mental state of a person who has the disease can be completely destroyed due
to stigmatization from friends and families except well managed through social therapy. The
continuing spread of the HIV/AIDS pandemic is mostly as a result of ignorance and lack of
acceptance of the fact of the existence of the disease amongst people. The disease is mostly
transmitted through sex, use of infected needles, blood transfusion and contact with infected
blood.
Today’s Internet technology is helping in the dissemination of information about the existence
and realities of the disease; and is also a tool for creating awareness, educating, and helping to
reach out to large number of people on how to control and stop the spread of the disease. Apart
from the use of the Internet, other media like television, radio, tabloid and seminars are also being
used.
The study has been able to make use of open source tools to develop a system which provides an
easy access and storage of large database of people living with HIV/AIDs which are mined so as
to enable prediction of the disease. The system also helps educate about the diagnosis, symptoms,
curative measures and prevention of the disease. Also, data gathered from people living had been
analyzed for effective decision support for the control and management of the disease. The
essence of the analysis is to further create awareness and foster major stakeholders in curbing the
spread of the world’s most dreaded disease.
