Mobile interactive messaging system for patients’ in collaboration with health workers
No full textHealth issues in developing countries are becoming more serious day by day, as different
diseases attack and infect people making the public health sector overwhelmed. This has made it difficult
for health workers to accurately study the trend of different diseases in many cases, thus failing to
analyze the way patients behave after being diagnosed. The number of people who possess mobile
phones is increasing every year and this can help facilitate communication in different geographical
locations that may hinder movement of the health workers. The initiative to introduce the use of
interactive messaging system is for patients who wish to access health services such as doctoral
appointments and consultations or need monitoring but are faced by challenges like; the time needed to
make for appointments and consultations, patients monitoring and halving to travel for long distances to
reach the facility.
Therefore the researcher designed and prototyped a mobile interactive messaging system that
would enable patients to send their preliminary symptoms to the health workers in Kenyan public
hospitals via SMS through mobile phones. With regard to the wide spread usage of mobile telephony
today, the researcher chose to use the technology since she anticipated it would reach a large
population. An interactive messaging system for patients’ collaboration with health workers is a system
that uses mobile phone technology that enables communication between patients and health workers.
This system’ will serve both the new and continuing patients. The health workers will monitor the
progress of continuing patients, while the new patients send their preliminary symptoms to the health
workers via SMS. All this information is stored in database residing at the health facility, which will serve
as a reference point to the health workers as they respond to the messages received and patients will be
able to effectively collaborate with the health workers without necessarily having to visit health facility
A MODEL FOR DETECTING INFORMATION TECHNOLOGY INFRASTRUCTURE POLICY VIOLATIONS IN A CLOUD ENVIRONMENT
No full textFULL TEXTThe pervasiveness of the internet and available connectivity solutions brought about by cloud computing has led to an unprecedented increase in technologies built based on information technology infrastructures. This has improved the number of cloud users and substantially increasing the number of incidents related to the security of infrastructure and data in the recent past. Most organizations consider the deployment of different types of protection systems to curb various malicious activities. Organizations offer sophisticated monitoring and reporting capabilities to identify attacks against the cloud environment. Users with ill intentions have increasingly used the cloud as an attack vector due to its ubiquity, scalability and open nature despite the existence of policy violation detection systems necessitating the need to strengthen access policies from time to time. Policy violation detection plays a major role in information security by providing a systematic way of detection and interpreting attacks. Some of the known weaknesses of most detection tools are the generation of false positives or false alerts and the inability to perform analysis if traffic is encrypted as well as failure to detect and prevent attacks. This research was therefore concerned with the investigation of weaknesses of firewall and Intrusion Detection Systems (IDS) which are supported by the cloud. The information was then used to build and experiment on an improved model of a policy violation detection system. Experiments revealed the weakness in existing systems specifically IDS and firewalls. Unlike the existing systems, a new model designed to overcome the shortfall was able to detect both recognized and unrecognized attacks and signatures. Moreover, the model is capable of preventing the occurrence of false positives and terminates suspicious nodes in real time without human intervention. An additional area of application such as movement from data from one cloud to another is not achievable, because of the mixed environment of the cloud. This is a potential area for investigation in the future
Evaluation of mechanisms that enable self- protection on policy violation in cloud Infrastructure
No full textFULL TEXTCloud computing is an emerging paradigm that involves all the basic components of computing
such as end-user machines (PCs), communication networks, access management systems and
cloud infrastructures. According to Gartner, while the hype grew exponentially during 2008 and
continued since, it is clear that there is a major shift towards the cloud computing model and that
the benefits may be substantial (Gartner Hype-Cycle, 2012). However, as the shape of the cloud
computing is emerging and developing rapidly both theoretically and in reality, the cloud
security, data and cloud infrastructure and privacy issues still pose significant challenges. It still
lacks mechanism to enable itself from policy violation.In this work, we describe various
mechanisms that would enable self-protection on policy violation in cloud infrastructure. In
particular, we discuss five critical mechanisms: IDS, Cyberoam, Federated Identity Management
System, firewall and honeypot. Some solutions to mitigate these attacks on these mechanisms are
also proposed along with a brief presentation on the future trends in cloud
computingdeployment. Finally we evaluate these mechanisms based on the data collected from
users in case they know how to protect their data in cloud environment.National Research Fun
An Architecture for Detecting Information Technology Infrastructure Policy Violations in a Cloud Environment
No full textFULL TEXTOrganizations are increasingly becoming aware of the business value that cloud computing
brings and are taking steps towards transition to the cloud. Just like any other technology it
brings new security threats and challenges. A smooth transition entails a thorough understanding
of the benefits as well as challenges involved. Privacy is a concern that has risen as obstacle to
widespread adoption of clouds by users. Many organizations consider the deployment of
different types of protection systems to curb the various malicious activities. The systems can
offer sophisticated monitoring and reporting capabilities to identify attacks against cloud
environment, while stopping multiple classes of attacks before they are successful against a
network. Despite the use of protection systems to detect any malicious activities, some users still
find ways to violate some of the laid down IT infrastructure Acceptable Use Policies. While
many cloud security research focus on enforcing standard access control policies typical of
centralized systems, such policies have often proved inadequate. For this reason, an architecture
has been developed to automatically detect IT infrastructure policy violation in a cloud
environment The implication of this research is that institutions would regain their trust in this
paradigm and consider implementing policies in their clouds. Since policy violation is one of the
major hindrances to the implementation of cloud computing, the policy violation detection
architecture could be employed by institutions to ensure data security in cloud environment. The
architecture uses software agents as its core components to collect evidence across cloud
environment. The architecture captures any policy violation in the cloud environment when
using any IT infrastructure. Therefore we discuss the policy violation detection architecture and
present our findings in this paper.National Research Fun
Perception of teachers on inclusive education in public regular primary schools in Homa bay sub- county, homa bay County
No full textPerception of teachers on inclusive education is vital because their perspective determine to what extent they practice inclusive education. Despite the progress in providing quality
inclusive education to learners with special needs, total inclusive education is yet to be
embraced in Kenya. This has made many learners with special needs to be excluded from
mainstream education. The purpose of the study was to examine the perception of teachers on inclusive education in public regular primary schools in Homa Bay Sub County. The
objectives of this study were to find out the perception of teachers on their attitude towards inclusive education; establish the academic and professional preparedness to implement inclusive education; to find out the perception of teachers on potential challenges facing them while implementing inclusive education and to find out the perception of teachers on possible strategies employed in the implementation of inclusive education in public regular primary schools. The study was guided by Lev Vygostsky’s constructionist theory of learning and used an ex post facto research design. The study targeted six schools with a total of 99 teachers and 2 Educational Assessment Research Centre coordinators. (EARC). Using 30% of the target population, a sample size of 30 teachers was selected through simple random sampling technique and 2 EARC coordinators through saturated sampling technique to participate in the study. Data collection instruments were interview schedules and focus group discussions. Data triangulation, member checking, and external auditors enhanced trustworthiness of qualitative instruments. Thematic analysis approach was used for qualitative data analysis. The study findings indicate that the natures of attitudes of teachers from different backgrounds are different. Teachers whose teaching experience was above11 years in primary schools held more positive attitudes towards inclusive education; most
teachers are not trained to teach learners with special needs; challenges that affect teachers in inclusive education include lack of teaching and learning resources and non-cooperation of parents; strategies employed were consultation with the community and parents along with seminars and in-service training for teachers. In inclusive education, commitment to change, with training and cooperation from parents, children, and teachers can realize full inclusion. The study recommends that teachers should plan to have more time to provide remediation for learners with special needs. It also recommends that teachers should be sensitized by relevant stakeholders to develop positive attitudes towards the implementation of inclusive education in primary schools
The challenge of feminism in Kenya : towards an Afrocentric worldview
No full textThis study deals with African women's literature, and specifically creative writing by Kenyan women, in the context of feminism and Afrocentricity. In the words of Obioma Nnaemeka (1995) critics of African women's literature have tended to rename, misname or silence women's voices in an attempt to make them fit into a feminist! Afrocentricity either or mould. This thesis argues that when attention is paid to African women
themselves, and the cultures from which and within which they write, it is clear that they embrace both feminism and Afrocentricity. By feminism I refer to African women's vision and activism for sexual equality and women's liberation while by Afrocentricity I am thinking of their commitment and pride in their African cultures and
traditions.
The first chapter argues that Kenyan women, in pre-colonial, colonial and post-colonial times, have been active and voiced in their stance against oppression of any kind. In the second chapter, I explore the relationship between feminism and Afrocentricity in a wider sense. I pay attention to the ways in which the two concepts have manifested themselves in Africa and her Diaspora as well as in the western world. In chapter three, domestic violence, rape, poverty, and a gender insensitive legal and judiciary
system are the dominant issues of concern to short stories writers from Kenya. In the fourth chapter, Ogot is seen as a liberal Afrocentric feminist in her call for African
women to create room for themselves within African systems of thought and practice. Chapter five, on Oludhe Macgoye, argues that to be Afrocentric is cultural rather than
racial. In Chapter six Rebeka Njau and Margaret Ogola are seen as Afrocentric while Tsitsi Dangarembga and Alice Walker are seen as Eurocentric. The thesis concludes that feminism in practice is not necessarily an occidental phenomenon. An African woman writer can be both feminist and Afrocentric
