E-Medical Consultation for Diagnosis and Treatment of Hypertension in Pregnancy: an Opportunity to achieve the 5 th Millennium Development Goal in Kenya

Jael GUDU, David GICHOYA, Alex MUUMBO and Paul NYONGESA

ABSTRACT

This study sought to establish the challenges that the Reproductive Health Division (High Risk Pregnancy Clinic) at Moi Teaching and ReferralHospital based in Eldoret city, one of the two referral hospitals in Kenya, faces in adopting e-medical consultation as a way of improving maternal healthcare for patients with hypertension in  pregnancy and reducing maternal deaths.  In this paper, an outline of the strategies and pillars that the Clinic needs to adopt to embrace the use of e-medical consultation for the diagnosis,  treatment and management of hypertension in pregnancy is presented. The survey conducted established that the division is still lagging behind and has not adopted the use of e-health, especially in the consultation sessions between the doctors and patients. The outlined strategies when implemented will help steer the Reproductive Health Division (High Risk Pregnancy Clinic) towards making healthcare services available in an efficient and effective way to expectant women with the condition.  The model  could be adopted to extend the same to less endowed areas around the globe, where specialist: patient ratio is low

Evaluating Geographical Information Systems: A Case of Uganda Public Sector

Edward KURWAKUMIRE

ABSTRACT

Geographical Information Systems (GIS) are being implemented in the public sector because of their potential to improve service delivery. The impact of GIS is however, often not measured in practice. This study investigates the current GIS evaluation practices in the context of the public sector of Uganda. This encompasses the various methodologies employed in practice in GIS evaluation. This research adopts an interpetivist stance with an object to understand, learn and explain the evaluation and not only to perform the evaluation. The findings reflect that 40% of the surveyed organisations are evaluating their GIS. Questionnaire surveys, stakeholder needs assessment and project evaluations are the common evaluation methods. Lack of evaluation is attributed to human resource and financial constraints. This study reflects that GIS evaluation is still a concept under development in the context of the public sector of Uganda. The evaluations carried out in practice are mostly informal and summative.

Time Domain Modeling Of A Band-Notched Antenna For UWB Applications

S. MRIDULA, Binu PAUL, P. MYTHILI and P. MOHANAN

ABSTRACT

The time domain modeling of a coplanar wave guide (CPW) fed  band-notched  antenna for UWB applications is presented. The annular ring antenna has a dimension of 36×36 mm 2 when printed on a substrate of dielectric constant 4.4 and thickness 1.6 mm. The uniplanar nature and compact structure of the antenna make it apt for modular  design. The crescent shaped slot provides a notch in the 5.2-5.8 GHz frequency band to avoid interference with WLAN. The pulse distortion is insignificant in the operating band and is verified by the measured antenna performance with high signal fidelity and virtually steady group delay.

The Utilization of High-Frequency Gravitational Waves for Global Communications

Robert M. L. BAKER, Jr. and Bonnie S. BAKER

ABSTRACT

For over 1000 years electromagnetic radiation has been utilized for long-distance communication. heliographs, telegraphs, telephones and radio have all served our previous communication needs. Nevertheless, electromagnetic radiation has one major difficulty: it is easily absorbed. In this paper we consider a totally different radiation, a radiation that is not easily absorbed: gravitational radiation.  Such radiation, like gravity itself, is not absorbed by earth, water or any material substance. In particular we discuss herein means to generate and detect high-frequency gravitational waves or HFGWs, and how they can be utilized for communication.  There are two barriers to their practical utilization: they are extremely difficult to generate (a large power required to generate very weak GWs) and it is extremely difficult to detect weak GWs. We intend to demonstrate theoretically in this paper their phase-coherent generation utilizing an array of in-phase microelectromechanical systems or MEMS resonator elements in which the HFGW flux is proportional to the square of the number of elements. This process solves  the transmitter difficulty. Three HFGW detectors have previously been built; but their sensitivity is insufficient for meaningful HFGW reception; greater sensitivity is necessary. A new Li-Baker HFGW detector, discussed herein, is based upon a different measurement technique than the other detectors and is predicted to achieve a sensitivity to satisfy HFGW communication needs.

The Sustainable Engineering Design Model: Necessity or Luxury

Anthony D. Johnson, Andrew G. Gibson and Dr. S. M. Barrans

ABSTRACT

Sustainability in the field of the design of the built environment has been successfully applied for thousands of years, where materials have been reused and recycled.  More recently there has been a great emphasis on sustainability in the field of geographic sciences. Engineering design is a vast subject covering an enormous range of disciplines, but sustainability issues have rarely been applied to engineering design. This paper outlines the normally accepted general design model and proposes a model for sustainability as applied to mechanical engineering design.  Issues such as sustainable sourcing of materials, ecological design approach, sustainable use of new equipment and sustainable decommissioning using the 4r approach are all explored.Taguchi proposed that the quality of engineering products could be defined at the design stage rather than at the  manufacturing stage.  The same is true of the application of  sustainability where engineering designers should instigate sustainable engineering in new  designs.  Furthermore, correctly applied sustainable design techniques will reduce costs and improve the Triple Bottom Line.

Serious Gaming to Improve the Safety of Central Venous Catheter Placement

Daniel Katz and Samuel DeMaria

ABSTRACT

Approximately 5 million central venous catheters (CVCs) are placed by physicians annually in the United States, with a complication rate of 15%.1 Guidelines and recommendations are continually being established and updated regarding CVC placement.2  While much has been done regarding training the technical skills of CVC placement using part-task trainers (i.e., mannequins), successfully finding and cannulating a central vein is but one part of the process. In fact, many steps designed to prevent untoward complications involve non-technical skills which are perhaps more important in training practitioners to safely place CVCs.

First in aviation and now in healthcare, practitioners are being trained in realistic and highly interactive simulated environments so they can learn not just technical skills , but the key management and non-technical steps which make their task safer.3  One modality being used to improve performance is video gaming simulation, or “serious gaming.”  Gaming as a learning tool is being increasingly utilized in health care fields and can lead to better skill-based outcomes.4 As such, we have developed a game based around the placement of CVCs that will be used as a new teaching modality in a pilot program for instructing residents in safe CVC placement.

Sequential Metamodeling Approach for Optimum Design of Contact Springs Used in Electrical Connectors

Kun-Nan CHEN

ABSTRACT

In this paper, optimum designs of a contact spring used in an electrical connector are achieved using a sequential metamodeling approach, with the objective function of the optimization problem being defined as the maximum von Mises stress in the contact spring. In order to ease the computational burden of the optimization process, the procedure is split into two stages, each with four design variables. This two-stepped scheme utilizes the Face-centered central composite experimental design concept, performs non-linear contact finite element analysis on every design point, builds response surface models with regression analysis, and uses the quadratic programming technique to optimize the approximated models.
