Early Weaning Risk Factors for Acute Respiratory Infections

10.11591/ijphs.v6i2.6641
Eni Folendra Rosa , Gunardi Pome , D. Harsanto
Acute respiratory infections (ARIs) still a health problem in the world resulting in high mortality and morbidity. Every year 13 million children under five died, 95% of deaths occur in developing countries and 4.5 million deaths due to respiratory infection. Takes effort and hard work to reduce mortality of children under five are caused by ARIs. ARIs episodes in children under five in the world generally between 3-8 times every year. Breast milk is a natural nutrient that contain IgA (SIgA), IgE, IgM,  IgG, lactoferin, lysozyme, vitamin A, C and E. SIgA generated broncho mammary and α2--microglobulin substances that protect against syncytial virus and inhibit and lowering the risk of infection with Haemophilus influenzae contained in the mouth and nose. Babies who are not breastfed full or partial ARIs at greater risk due to lack of intake of protective substances in the breast milk. The incidence of acute respiratory diseases are at highest order resulting morbidity and mortality of children in the district OKU in 2014 amounted to 52.2% and increased by 53% in 2015. Unmatched case control study with a quantitative approach, the study subjects children aged 6-24 months. Data analysis using Stata program consists of univariable, bivariable and multivariable logistic regression with 95% CI. Significant relationship with ARIs early weaning (OR = 2.72  95% CI = 1.08 - 6.83). The average episode of ARIs was 2.8 times every year. Early weaning increase risk of ARIs in children 6-24 months.

Fariani Syahrul , Chatarina U. W. , Arief Hargono
Personal health, including health on school-age children comes from food intake. But often, these foods can cause health problems, such as foodborne diseases. A quasi-experimental study was conducted to monitor the Clean and Healthy Lifestyle (CHL) of children at school through the establishment and evaluation of child health cadres. Phases of activities are the selection of child health cadres (10 children), training and determination of the child that will be monitored (40 children), preliminary assessment on the monitored CHL, two-month monitoring and final assessment. Monitored CHL are the CHL associated with foodborne diseases such as clean nails, snacks habit, habit of bringing lunch, and hand-washing habit in schools. Descriptive analysis showed that there were differences between the CHL school children before and after the monitoring conducted by child health cadres, however the results of the Chi-Square Test indicated that only the habit of bringing lunch that yield a significant change  (p=0.01). Evaluation of the routine activity showed that the average cadre activity on monitoring is 75.7% and the average of completeness monitoring books is 91.9%. The activities of child health cadres can be applied on an ongoing basis with the school health program activities that have been established in schools.

Harmonic Compensation using STATCOM for SEIG Feeding Single-Phase Load Connected between Different Phases

10.11591/ijeecs.v6.i3.pp489-496
Satyanarayan Gorantla , Goli Ravi Kumar
The paper presents the analysis of harmonic distortion when non-linear load is connected in different phases of power system with STATCOM for singly excited induction generator system with wind turbine as prime mover. Now-a-days due to the drastically increased in use of non linear loads causes many power quality problems in power system network. Those problems are classified as reactive power problems, harmonics, voltage sags and swells. Out of these problems harmonic problems are major concern. Custom power devices proposed for mitigation of power quality in network. For compensation of harmonic, static compensator (STATCOM) is used. The paper presents the compensation of harmonic power quality issues using STATCOM for the system with singly-excited induction generator feeding non-linear load connected in different phases. STATCOM is controlled using synchronous reference frame theory to produce pulses to switches of STATCOM sensing the input parameters. Proposed concept was developed using MATLAB/SIMULINK software and results are presented for non-linear load connected in different phases of the power system. THD analysis was shown for source current and load current for different cases.

10.11591/ijeecs.v6.i3.pp671-681
Deevya Indoonundon , Tulsi Pawan Fowdur , Sunjiv Soyjaudah
H.264/AVC is currently the most widely adopted video coding standard due to its high compression capability and flexibility. However, compressed videos are highly vulnerable to channel errors which may result in severe quality degradation of a video. This paper presents a concealment aware Unequal Error Protection (UEP) scheme for H.264 video compression using Reed Solomon (RS) codes. The proposed UEP technique assigns a code rate to each Macroblock (MB) based on the type of concealment and a Concealment Dependent Index (CDI). Two interleaving techniques, namely Frame Level Interleaving (FLI) and Group Level Interleaving (GLI) have also been employed. Finally, prioritised concealment is applied in cases where error correction is beyond the capability of the RS decoder. Simulation results have demonstrated that the proposed framework provides an average gain of 2.96 dB over a scheme that used Equal Error Protection (EEP).

This study sought to assess the attitudes of Mental Health Professionals (MHPs) towards tackling illicit drug use and drug-related disorders in Nigeria and to explore regional variations in attitude. Based on the validated Substance Abuse Attitude Survey (SAAS), a quantitative cross-sectional survey was conducted in a randomized sample of 292 MHPs practicing in neuropsychiatric hospitals and mental health departments of teaching hospitals from four geopolitical zones of Nigeria. A response rate of 81.1% was achieved. MHPs tended towards non-permissive, moralistic and stereotypic spectrum and exhibited distinctly defined attitude towards their professional role. The Kruskal-Wallis analysis established significant regional variation in the attitude of multidisciplinary MHPs, H (3)=18.727, p< .0001 reflecting a stochastic domination across the region; therefore a step-down follow-up analysis was conducted. This analysis revealed that the distribution of attitude total-score varies significantly between the South-south and the Southwestern region (p< .0001), the northeastern and southwestern region of the country (p< .028).  A holistic approach towards standardization of drug treatment and care that takes into consideration possible regional variation in attitudes of MHPs should be implemented to foster the reintegration and rehabilitation of drug-using populations into the mainstream society.

An Assessment of Health-Economic Burden of Obesity Trends with Population-Based Preventive Strategies in a Developed Economy

10.11591/ijphs.v6i2.6642
Prerna Bhasin
The burden of obesity varies with age, ethnicity, socio-economic status and state economies. All new projections should hence accommodate population ageing, and other population changes such as immigration, health-care system reform, or technological advances for disease treatment for a comprehensible assessment of global burden. The unfordable and expensive nature for reversing the obesity tide arises from policies developed to combat obesity. Most of these approaches aim at bringing the problem under control, rather than affecting a cure, and obviously require a multi-disciplinary and intensive regimen. Prevention is the only feasible option and is essential for all affected countries. Yet it is not simple to have population based UK-wide strategic framework for tackling obesity. Besides existence of multiple layers of governance, there are clear demarcations between targets in diet; nutrition and physical activity level between regions some of which are not realistic.  Population based approaches target policies and process, aiming for a transition towards healthy population diets, activity levels and weight status. It is essential to understand these aspects differ culturally and between and within countries. There are still no clear and appropriate answers about answer when, where, why, and, how costs accrue in obese populations, further long term commitments are required for the same. Most population-based prevention policies are cost effective, largely paying for themselves through future health gains and resulting reductions in health expenditures. Therefore these prevention programs should be high on the scientific and political agendas.

Anthony Wambua Mathulu , Benard Wambua Mbithi
Each year, over 500,000 women die from the complications of pregnancy and child birth, almost all of them in the developing countries. This trend can be addressed by increasing the rates of skilled care during childbirth. This study therefore sought to establish the socio-cultural factors influencing uptake of skilled childbirth care which has remained low in Kaiti Division. The researchers applied a descriptive cross-sectional study design which involved women of childbearing age (15-49 years). The study was conducted in March 2010 and had a sample size of 246 women which was randomly selected from the estimated target population of 12,077. The researchers applied both quantitative and qualitative approaches. The tests of significance employed included Fisher’s exact test, chi-square, test and logistic regression. The study established that the proportion of women attended to by the skilled attendant within various age cohorts was higher (58.9%) amongst the youth/adolescent (15-24 years) (P-value = 0.091> 0.05, c2 10.915 df 6).). Skilled attendance declined among the grand-multiparas (para4 and above) from 7.7% in Para 4-5 to 2% in Para 6+ (P-value = .000<0.05, c2 34.888 df 3; Para 1(p =0.000, OR 28.391), Para 2-3 (p =0.000, OR 7.564), Para 4-5(p=0.030, OR 3.493) Further findings indicated that the principal decision maker (46.7%) on type of assistant in the last delivery was the woman (P-value = 0.000 <0.05, c2 56.076 df 5). However, the husband was the leading (39.5%) decision maker in use of a skilled assistant in the last delivery (p=0.000, OR 15.667). More than two thirds (70.7%) of the respondents who performed a ceremony prayed for safe delivery in their last delivery. The study concluded that women’s parity, decision making and religion were significant in use of skilled childbirth services.

This paper presents the modeling by Magnetic Equivalent Circuit model (MEC) of a Simple Excited Automotive Alternator (SE2A) where DC-excitation winding is transferred from rotor side to statorone rather than in conventional automotive claw pole alternators, to overcome the disadvantages of the ring-brush system. Following the resolution of the MEC using Newthon-Raphson numerical method, the alternator performances at both no-load and under resistive load regimes is achieved considering the saturation effect. It has been found that alternator’s performances carried out using the proposed MEC are with closed proximity to experimental records on a built prototype of the considered alternator.

10.11591/ijece.v7i3.pp1316-1325
Seyed Ehsan Yasrebi Naeini , Ali Maroosi
A Sampling rate is less than Nyquist rate in some applications because of hardware limitations. Consequently, extensive researches have been conducted on frequency detection from sub-sampled signals. Previous studies on under-sampling frequency measurements have mostly discussed under-sampling frequency detection in theory and suggested possible methods for fast under-sampling frequencies detection. This study examined few suggested methods on Field Programmable Gate Array (FPGA) for fast under-sampling frequencies measurement. Implementation of the suggested methods on FPGA has issues that make them improper for fast data processing. This study tastes and discusses different methods for frequency detection including Least Squares (LS), Direct State Space (DSS), Goertzel filter, Sliding DFT, Phase changes of Fast Furrier Transform (FFT), peak amplitude of FFT to conclude which one from these methods are suitable for fast under-sampling frequencies detection on FPGA. Moreover, our proposed approach for sub-sampling detection from real waveform has less complextity than previous approaches from complex waveform.

This paper discusses the development of an indoor monitoring system based on passive radio frequency identification (RFID) system and Raspberry Pi 3. There are two algorithms designed for this project where the first is to link the RFID module to the Raspberry Pi 3, and the other one is to send the data obtained to a database over wireless network via UDOO Quad as a secondary router. The result is then displayed on a localhost generated using XAMPP. The objective of this project is to realize a monitoring system that incorporates different systems such as Raspberry Pi 3, UDOO Quad, and also RFID module by designing algorithms using Python and C programming language. Plus, the performance of the system is also analyzed using different type of antennas such as the Raspberry Pi 3 Antenna, monopole antenna, and a Yagi Uda antenna in terms of power received versus distance in both line of sight position and non-line of sight position. Finally, antenna that produces the best performance for line-of-sight (LOS) propagation is Yagi Uda antenna while monopole antenna is better when it comes to non-line-of-sight (NLOS) propagation.

The use of distributed generation (DG) within distribution systems has increased for the last two decades due to worldwide increase in demand for electricity and governmental policy change from “conventional” energy to “green” energy. High levels of penetration of DG have many significant benefits but also come with many drawbacks such as voltage drop and power losses. This study presents the impact of DG at different locations in a distribution feeder in terms of the feeder voltage profile. A radial distribution system is simulated using PSCAD/EMTDC simulation software while changing the size and location of DG in the system. The obtained results are used for better understanding on the impact of DG on voltage profile in radial distribution feeder.

The accurate land use land cover (LULC) classifications from satellite imagery are prominent for land use planning, climatic change detection and eco-environment monitoring. This paper investigates the accuracy and reliability of Support Vector Machine (SVM) classifier for classifying multi-spectral image of Hyderabad and its surroundings area and also compare its performance with Artificial Neural Network (ANN) classifier. In this paper, a hybrid technique which we refer to as Fuzzy Incorporated Hierarchical clustering has been proposed for clustering the multispectral satellite images into LULC sectors. The experimental results show that overall accuracies of LULC classification of the Hyderabad and its surroundings area are approximately 93.159% for SVM and 89.925% for ANN. The corresponding kappa coefficient values are 0.893 and 0.843. The classified results show that the SVM yields a very promising performance than the ANN in LULC classification of high resolution Landsat-8 satellite images.

In Mobile Ad hoc Networks (MANETs) there are some security problems because of portability, element topology changes, and absence of any framework. In MANETs, it is of extraordinary significance to identify inconsistency and malignant conduct. With a specific end goal to recognize malignant assaults by means of interruption identification frameworks and dissect the information set, we have to choose some components. Thus, highlight determination assumes basic part in recognizing different assaults. In the writing, there are a few recommendations to choose such elements. For the most part, Principal Component Analysis (PCA) breaks down the information set and the chose highlights. In this paper, we have gathered a list of capabilities from some cutting edge works in the writing. Really, our reproduction demonstrates this list of capabilities identify inconsistency conduct more precise. Likewise, interestingly, we utilize PCA for investigating the information set. In contrast to PCA, our results show Sequential pattern mining (SPM) cannot be affected by outlier data within the network. The  normal and attack states are simulated and the results are analyzed using NS2 simulator.
