Caregivers' knowledge and practice toward pressure ulcer prevention in national orthopedic hospital, Enugu, Nigeria

Introduction: Globally, nurses are known to care for hospitalized patients and the presence or absence of pressure ulcers is being regarded as a performance measure of quality nursing care. The study aims to determine the knowledge and practice of caregivers towards pressure ulcer prevention for hospitalized patients in National Orthopaedic Hospital, Enugu. Method: A cross sectional descriptive survey design was adopted among eighty-five (85) caregivers who met the inclusion criteria and participated in the study. Ethical approval and informed consent of participants was obtained before data collection using a pre-tested semi-structured questionnaire and checklist. Descriptive analysis and Chi-square statistical test was used to test for association between variables. Result: Results revealed poor knowledge 67.3% of pressure ulcer prevention among caregivers. Inadequate staffing 93.5%, heavy workload 92.9%, were highest perceived barriers to pressure ulcer prevention. The test of hypothesis showed that there is a significant relationship between years of service of caregivers and knowledge of pressure ulcer P = 0.000. Conclusion: It was concluded that in-service training, recruitment of more staff and ensuring availability of the necessary equipment are some of the important steps to improve nurses' knowledge and practice regarding prevention of pressure ulcer.
Characteristics of and risk factors associated with self-reported sexual repression among internal migrants in China: A large-scale cross-sectional study

Objective: This large-scale cross-sectional study aims to identify the characteristics of and risk factors associated with sexual repression among internal migrants in China. Methods: Between August 2013 and August 2015, a total of 8,669 internal migrants from four major cities in China (Beijing, Shanghai, Chengdu, and Chongqing) voluntarily participated in our study. They were interviewed, and the data on their demographic information, occupation, and sexual activities were collected. The Chi-square test and multiple logistic regressions were conducted to identify significant associations. A stepwise method was adopted for the selection of variables. Results: There were 3,597 (41.49%) males and 5,072 (58.51%) females in total. A higher percentage of males reported that they felt sexual repression compared to females (14.43% vs. 9.21%). After adjusting for other covariates, the consequence was showed that male migrants working for more than 5 days were more likely to report sexual repression (odds ratio [OR] = 1.40, P < 0.05). Living in a collective dormitory with others was also a risk factor for male migrants. The longer males spent with their partners, the less sexual repression occurred (OR= 0.94, P < 0.05). Similarly, agricultural household registration status and working for more than 5 days increased the risk for sexual repression among female migrants (OR= 1.41 and OR = 1.46, respectively, P < 0.05). Frequent and constructive communication also protected females against sexual repression (P < 0.05). Well-educated females experienced relatively less sexual repression when compared to their counterparts with less education (P < 0.05). Conclusions: Sexual repression was significantly associated with a few demographic, occupational, and sexual risk factors. Meaningful differences have been identified between male and female migrants. More effective intervention programs such as safeguard measures and welfare policies should be designed and implemented for a majority of female migrants and for those with agricultural household registration status.

A sample power quality survey for emerging competitive electricity market in Pakistan

The power sector in Pakistan, like in other countries, is passing through a restructuring process, i.e. from monopolized/state owned power system to competitive power market. Competition in n open market requires definition and comparative measurement of power quality, as a product. Additionally, poor power quality has already caused serious damage to industrial base and needs. This paper focuses on power quality problems in Pakistan and generally in third world countries. A detailed power quality measurements survey was performed for general and internationally defined power quality aspects. Some of the power quality aspects were then simulated to confirm the results. This power quality survey and simulations will provide an estimate of power quality levels, which will help and give direction for defining local power quality standards, specific remedies, and penalties to sources of power quality problems/polluters. Based on the sample power quality survey, certain conclusions and recommendations were developed.
VIP-an input pattern generator for identifying critical voltage drop for deep sub-micron designs

We present a novel input pattern generator for dynamic power network simulation. The obtained patterns successfully identify critical voltage drop areas for a set of industrial designs, which are difficult to be found using functional vectors. The search engine of the pattern generator for worst-case IR voltage drop is based on the multiobjective genetic algorithm. To achieve high coverage for critical voltage drop cells, we propose to model the search criteria into the maximum weighted matching of a bipartite graph, and guide the search direction according to the matching results. Experimental results show that, compared with the other approaches, our patterns give a higher coverage of critical voltage drop cells.
An empirical study of the scalability aspects of instruction distribution algorithms for clustered processors

In the sub-micron technology era, wire delays are becoming much more important than gate delays, making it particularly attractive to go for decentralized processors. A number of algorithms have already been proposed for distributing instructions among multiple clusters. In this paper we qualitatively and quantitatively analyze the effect of various hardware parameters on the scalability of different instruction distribution algorithms. Using a set of realistic system parameters, we examine performance differences resulting from different distribution algorithms as well as from specific implementation issues such as the type of interconnect, the fetch size, the cluster issue width, and the cluster window size. Our studies have found that those distribution algorithms that perform relatively better with 4 or fewer clusters are generally not the best ones for a larger number of clusters. Also, the relative performance and scalability of the algorithms are sensitive to different hardware parameters. We also found that, among the existing algorithms, there is no single algorithm that works uniformly best across all hardware configurations. This motivates the need to develop alternate interconnects and instruction distribution algorithms.
Video distortion analysis and system design for wireless video communication

of Dissertation Presented to the Graduate School of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy VIDEO DISTORTION ANALYSIS AND SYSTEM DESIGN FOR WIRELESS VIDEO COMMUNICATION By Zhifeng Chen December 2010 Chair: Dapeng Wu Major: Electrical and Computer Engineering In this dissertation, we address the problem of minimizing the end-to-end distortion in wireless video communication. We first analytically derive transmission distortion as a function of video statistics, channel conditions and system parameters for wireless video communication systems. Then we design practical algorithms to estimate the system parameters and video statistics. Given the channel condition, we may accurately predict the instantaneous transmission distortion by our formulae and estimation algorithms. We also prove a new theorem to extend our algorithms to support rate-distortion optimized mode decision in practical video codecs. Finally, we derive a more accurate source bit rate model and quantization distortion model than existing parametric models. Our models help us to design a rate-distortion optimized cross-layer rate control algorithm for minimizing the end-to-end distortion under resource constraints in wireless video communication systems. Our results achieve remarkable performance gains over existing solutions.
A Spectrum Prediction Approach based on Neural Networks Optimized by Genetic Algorithm in Cognitive Radio Networks

Cognitive radio enabled dynamic spectrum access is a promising solution to alleviate the spectrum low-utilization problem. Secondary users need to sense the bands before transmitting on them to avoid collision with the licensed users. To reduce delay and energy consumption of spectrum sensing, spectrum prediction is incorporated to predict the future usage of channels before spectrum sensing. In this paper, a three-step ahead spectrum prediction framework is designed based on neutral network, which is optimized by generic algorithm to avoid the local optimization problem. As it is difficult to obtain the statistics of channel usage in CR networks, the neural network based on genetic algorithm model does not require a priori knowledge of the underlying distributions of the observed process. Simulation results show that the proposed scheme can predict spectrum usage effectively and significantly improve the prediction accuracy compared to traditional neural network based prediction algorithms.
A systolic RSA public key cryptosystem

A bit-level systolic array for RSA public key cryptosystem is designed based on our modified Montgomery's algorithm. Since the post adjustment in the original algorithm is removed, the modified algorithm leads to both simpler architecture and better performance, A prototype CMOS VLSI chip was designed and simulated, which implements a 512-bit RSA cryptosystem. This chip can achieve an encryption (or decryption) rate of 24.3 Kb/sec under a 50 MHz clock.
Emotions in robot design

Investigates the role emotions might play in robot design. It is argued that if one wants to deal with this problem one first has to develop a profound understanding of the mechanisms underlying behaviors which are called emotional. To investigate the relation between behavior and mechanism the "New Fungus Eater" approach is proposed, which is a minimalist bottom-up approach. It is shown that often one can achieve certain desired behaviors with surprisingly cheap designs if the dynamics of the system-environment interaction is appropriately taken into account. The authors conclude by pointing out major differences between traditional and robot programming. <<ETX>>
Homeland security education: Managerial versus nonmanagerial market perspectives of an academic program

ABSTRACT The authors discuss the findings of a market study that preceded the offering of an academic program in homeland security. The university disseminated a mail survey to gain data for analysis of variance testing of several hypotheses regarding market perceptions of the intended homeland security program offering. Stratification involved segregating responses into categories of managers versus nonmanagers. Four statistically significant findings were observed regarding perceptions of course titles, academic program characteristics, degree types, and degree titles. The outcomes of the study are described within the article, and recommendations regarding the implications of the market study are discussed.
On the asymptotic eigenvalue distribution of concatenated vector-valued fading channels

The linear vector-valued channel x/spl rarr/ /spl Phi//sub i/M/sub i/x+z is analyzed in the asymptotic regime as the dimensions of the matrices and vectors involved become large. The eigenvalue distribution of the channel's covariance matrix is given in terms of its Stieltjes transform. The channel gets more and more ill-conditioned the more factors appear in the product. The study is of interest for cellular radio channels with receiving/transmitting antenna arrays.
Comparative delay and energy of single edge-triggered and dual edge-triggered pulsed flip-flops for high-performance microprocessors

Flip-flops and latches are crucial elements of a design from both a delay and energy standpoint. We compare several styles of single edge-triggered flip-flops, including semidynamic and static with both implicit and explicit pulse generation. We present an implicit-pulsed, semidynamic flip-flop (ip-DCO) which has the fastest delay of any flip-flop considered, along with a large amount of negative setup time. However, an explicit-pulsed static flip-flop (ep-SFF) is the most energy-efficient and is ideal for the majority of critical paths in the design. In order to further reduce the power consumption, dual edge-triggered flip-flops are evaluated. It is shown that classic dual edge-triggered designs suffer from a large area penalty and reduced performance, prohibiting their use in critical paths. A new explicit-pulsed dual edge-triggered flip-flop is presented which provides the same performance as the single edge-triggered version with significantly less energy consumption in the flip-flop as well as in the clock distribution network.

From Human Factors to Human Actors

I believe that there needs to be a better understanding among researchers, and many system designers too, about the "users" of computer systems and the settings in which they work. Part of the problem resides in an implicit view of ordinary people which, if surfaced, would seem to treat people as, at worst, idiots who must be shielded from the machine, or at best, as simply sets of elementary processes or "factors" that can be studied in isolation in the laboratory. Although psychology, particularly as represented by the fi eld of human factors (HF), or ergonomics, has had a long tradition of contributing to computer systems design and implementation it has often neglected vitally important issues such as the underlying values of the people involved and their motivation in the work setting.
Power minimization in LUT-based FPGA technology mapping

We consider the problem of lookup table (LUT) based FPGA technology mapping for power minimization in combinational circuits. The problem has been previously proved to be NP-hard, and hence we present an efficient heuristic algorithm for it. The main idea of our algorithm is to exploit the "cut enumeration" technique to generate possible mapping solutions for the sub-circuit rooted at each node. However, for the consideration of both run time and memory space, only a fixed-number of solutions are selected and stored by our algorithm. To facilitate the selection process, a method that correctly calculates the estimated power consumption for each mapped sub-circuit is developed. The experimental results indicate that our algorithm reduces the average power consumption by up to 14.18%, and the average number of LUTs by up to 6.99% over an existing method.
Capacity and mutual information of broadband multipath fading channels

We investigate the capacity and mutual information of a broadband fading channel consisting of a finite number of time-varying paths. We show that the capacity of the channel in the wide band limit is the same as that of a wide band Gaussian channel with the same average received power. However, the input signals needed to achieve the capacity must be "peaky" in time or frequency. In particular, we show that if broadband white-like signals are used (as is common in spread spectrum systems), the mutual information is inversely proportional to the number of distinguishable paths.
Operational simulation of an X-ray lithography cell: comparison of 200 mm and 300 mm wafers

We review progress on a project to evaluate prospective operations in a semiconductor wafer fab that employs next generation, proximity X-ray lithography to pattern the critical dimensions of computer chips. A simulation model is developed that captures the processing of wafers through an X-ray lithography cell using a synchrotron as the source of exposure radiation. The model incorporates the best current information on unit-cell design and processing times and implements a range of events that interrupt the flow of wafers processing on the cell. Performance measures estimated from the simulation include the weekly throughput for the cell and the frequency of SEMI E-10 equipment states for the corresponding exposure tool. Simulation experiments are conducted to compare the performance of a cell fabricating 200 mm wafers with that of a cell fabricating 300 mm wafers, for each of three different chip sizes. Results illustrate the anticipated dependence of average wafer throughput on wafer size and assumptions regarding the number of chips per wafer, with a maximum of approximately 3400 wafers/week for 200 mm wafers with 25/spl times/25 mm field size. Ignoring wafer-sort losses, however, a maximum throughput of approximately 410,000 chips/week is realized for 300 mm wafers with 11/spl times/22 mm fields. Remarkably, the distribution of equipment states remains relatively unchanged across simulation experiments.
Implementing AI-ESTATE in a component based architecture. Phase-I

This paper discusses an Air Force funded SBIR Phase-I R&D project concerned with the feasibility of implementing AI-ESTATE in a component based Automatic Test System (ATS). Component technology extends the notion of client/server interactions by building client-sides and service-sides into each component running in separate program spaces. Component connectivity and interoperations are facilitated via COM and CORBA enabling technologies. Al-ESTATE is a new set of IEEE standard services designed to support Artificially intelligent diagnostic reasoners running in an ATS environment. A component-based ATS architecture provides two distinct locations to construct Al-ESTATE services in the inter-component communications unit (layer) and as stand alone components.
Mapping iterative algorithms onto processor arrays by the use of Petri Net models

In this paper, Petri Nets (PNs) are used for deriving efficient mapping transformations of a wide class of algorithms to processor arrays. In the proposed methodology, given an algorithm and the interconnections of the processor array, two PNs are constructed: one that is related to the algorithm and one that is related to the processor array. The former PN models the execution of the algorithm and differs drastically from the common data-flow methods. Based on properties of PNs and on the reachability tree analysis technique, a theorem is given, through which the two PN model suggest all possible ways of implementing the algorithm by the processor array. <<ETX>>
The Impact of Using the Integration Approach between Science and Math on Acquiring the Skills for Solving Scientific Problems for Fourth Grade Students

This study aimed to investigate the impact of using the integration approach between science and math on acquiring the skills for solving scientific problems for fourth grade students of Basic Education in the Sultanate of Oman. The study sample consisted of 117 fourth grade students selected from one Basic Education school. The sample was divided into two groups: an experimental group, which consisted of 59 students who studied scientific activities integrated with mathematical knowledge and skills through the teacher guide which was designed specifically for the purpose of the study. The second group was the control group, which consisted of 58 students who studied the same activities through the conventional method of teaching. The experimental group students were taught by a cooperating teacher who had received training on how to employ the integrated activities. Both groups studied the same topics for eight weeks during the second semester of the academic year 2008/2009. To answer the research question, a posttest for scientific problem-solving skills with a reliability value of (0.88) was prepared and administered for both groups. Results revealed that there was a statistically significant difference at (α = 0.05) between the two groups in scientific problem-solving skills in favour of the experimental group. The study also showed that there was a statistically significant growth of scientific problem-solving skills in the experimental group. Accordingly, the study recommends training students to use integrated activities which require implementation of mathematical skills and processes in order to solve scientific problems in science.
