Aim of the study: To evaluate the value of uterine artery Doppler indices and waveformpattern in predicting fetuses at risk for intrauterine growth restriction in hypertensive
disorders of pregnancy. Materials and methods: This was a prospective cross-sectional
study including 80 pregnant subjects with hypertensive disorders of pregnancy and two
control groups. Uterine artery Doppler sonography was performed in all study participants.
Uterine artery Doppler indices across the groups were compared using the analysis
of variance (ANOVA) while the presence of prediastolic notch was analyzed with the Chi
Square test. Results: For the hypertensive disorders of pregnancy group, resistivity index
> 0.66 had a sensitivity of 50.0%, specificity of 69.1% and a positive predictive value of
22.2% for predicting intrauterine growth restriction. The odds ratio was 2.2 with a 95%
confidence interval of 0.6–7.8. The presence of prediastolic notching had a sensitivity of
100.0%, specificity of 96.0% and a positive predictive value of 80.0% for predicting intrauterine
growth restriction. The odds ratio was 22.7 with a 95% confidence interval of
7.5–68.5. Conclusion: Uterine artery Doppler sonography is useful for predicting fetuses
at risk for intrauterine growth restriction in hypertensive disorder of pregnancy. Prediastolic
notching is more sensitive and more specific than uterine artery resistivity index in
predicting fetuses at risk of intrauterine growth restriction in established hypertensive
disorder of pregnancy.

Aim: Intimate partner violence (IPV) is a public health issue in both developed and developingcountries. It is one of the most common forms of violence against women. It affects all ethnic
groups and it is not impeded by cultural, socio-economic or religious barriers. IPV in postpartum
women can increase the risk of homicide and suicide. The study aimed to assess the prevalence,
pattern and correlates of IPV among postpartum women attending postnatal and infant welfare
clinics of LAUTECH Teaching Hospital, Osogbo.
Study Design: This was a cross-sectional study.
Place and Duration of Study: This study was conducted at LTH, Osogbo Nigeria between
September and November 2015.
Methodology: This was study conducted among 220 consenting postpartum women using
Composite Abuse Scale and socio-demographic questionnaire. Data were analyzed usingStatistical Package for Social Sciences (SPSS) version 21. The level of statistical significance was
set at p-value less than 0.05.
Results: Prevalence of IPV was 26.8%, patterns of IPV were physical abuse 14.5%. Emotional
abuse, 26.3, severe combined abuse 9.9% and Harassment 14.5%. IPV was significantly
associated with support from respondents’ partner during pregnancy (χ2= 5.470, p=0.019) and
partner’s religion. (χ2= 7.746, p= 0.010) The odd ratio for those who had partner’s support was less
than 1. (OR =0.337, p=0.014, CI=0.141-0.803).
Conclusion: The prevalence of IPV is high among postpartum women. Increased media campaign
about intimate partner violence and preventive measures is urgently needed.

Wireless networks are prone to security attacks due mainly to the open nature of its transmission medium (open air). Hence wireless network security is more concentrated and complex than that of a wired network. With the advent of wireless network technologies in the market today, mobility has becomes an important requirement for most university networks. A lot of attention has been given to the provision of wireless infrastructures in the University networks, but little attention has been given to wireless network security in a University environment. The current wireless network security implemented in Universities are weak, making it possible for hacker to break into University networks and hack confidential information of students, staffs and faculty members. In this paper we propose a peer-to-peer security architecture with certificate based mutual authentication of client and network through an encrypted tunnel and dynamic per user, per session WEP keys, using only server side certificates. This will control access to the network by allowing infrastructures to authenticate users and not wireless hosts using a centralized authentication server system, RADIUS server and LDAP or Active directory server. This will allow users to use their regular username and password pair to access the network.

The lack of current network dynamics studies that evaluate the effects of new application and protocol deployment or long-term studies that observe the effect of incremental changes on the Internet, and the change in the overall stability of the Internet under various conditions and threats has made network monitoring challenging. A good understanding of the nature and type of network traffic is the key to solving congestion problems. In this paper we describe the architecture and implementation of a scalable network traffic moni-toring and analysis system. The gigabit interface on the monitoring system was configured to capture net-work traffic and the Multi Router Traffic Grapher (MRTG) and Webalizer produces graphical and detailed traffic analysis. This system is in use at the Obafemi Awolowo University, Ile-Ife, Nigeria; we describe how this system can be replicated in another environment.
