Peak-to-average power ratio reduction in wavelet packet modulation Using Binary Phase Sequence.

10.11591/ijeecs.v14.i3.pp1210-1219
Vijaya M. Kulkarni , A. S. Bhalchandra
A novel method of Peak–to-Average–Power-Ratio reduction is presented in this paper using  WPT  for multi carrier modulationand Riemann matrix for phase sequencing in SLM. Wavelet Packet Multicarrier Modulation(WPM) is a betteralternative to the existing multicarrier transmission system,OFDM system which suffers from high PAPR.Further reduction in Peak to Average Power Ratio (PAPR)is achieved by using Wavelet Packet Modulation(WPM) with SLM technique. Classical SLM uses random phases for phase rotations which  suffers from the additional load  of transmitting SI(side Information) to receiver. So to overcome a novel method is proposed here  which uses  the principle of varying the phases of the subcarrier data block to be transmitted ,using rows of the normalised Reimann matrix as phase sequence vectors for the Selected Mapping (SLM)Technique. The generated WPM frame with minimum PAPR is selected and transmitted .The proposed system achieves a significant improvement in PAPR reduction over the OFDM-classical SLM and WPM-classical SLM.

Abdu Oumer
For appropriate management of severe acute malnutrition skilled, knowledgeable and concerned health professionals are critical for child survival. Thus assessing the knowledge of nurses towards management protocol of severe acute malnutrition is crucial step for targeted interventions. This study aimed to assess Knowledge towards Severe Acute Malnutrition Management Protocol and its Associated Factors among Nurses working in Hiwot Fana Specialized University Hospital, 2018. Cross-sectional study was conducted among eligible 132 nurses. Data were collected using self-administered questionnaire prepared from the national SAM management guideline of Ethiopia. SPSS version 20.0 software using frequency, tables, graphs, percentages and mean was used. Student t test and analysis of variance with F statistics and P value was computed. Overall, 65 (49.2%) of nurses had poor knowledge on SAM management. More than half, 100 (75.8%) of the nurses had experience in SAM management previously. Males were more likely to be knowledgeable (AOR=1.27) as compared to females. Nurses with the previous experience of managing malnourished child had 1.70) times more likely to be knowledgeable as compared to their counterparts. Having SAM training was associated with having higher knowledge score (AOR=1.56). Having SAM training was found to have significantly higher knowledge score (p=0.034). Knowledge level of nurses towards SAM management is not satisfactory. Those who ever involved in SAM management, having recent malnutrition training and gender were predictors of high knowledge score. There should be regular capacity building schemes for nurses especially for those who are involved in management of SAM at emergency or SAM unit.

Design of parallel and pipelined DA based OBC fir filter for software defined radio

10.11591/ijeecs.v14.i3.pp1228-1234
Rajmohan Madasamy , Himanshu Shekhar
Software Defined Radio (SDR) is a new technology used to implement different wireless communication standard for mobile communication. The Intermediate Frequency (IF) block is the most demanding block in software defined radio. The most important task in intermediate processing block is digital filtering which is carried out by Finite Impulse Response (FIR) filter. One of the major techniques for the calculation of inner product is Distributed Arithmetic (DA) based FIR filter which uses Look Up Table (LUT) to eliminate the need of multiplier. The efficiency of the DA filter is affected with the increasing number of address line and also due to its serial operation. To overcome this problem parallel and pipeline based DA filter using Offset Binary Coding (OBC) for Two Bit At A Time (2-BAAT) is proposed. Our proposed method achieves less area, low power consumption and nominal delay for SDR application.

Pregnant mothers’ knowledge, attitude and practice towards preventions of iron deficiency anemia in Harar town, Ethiopia

10.11591/ijphs.v8i2.19476
Abdu Oumer Abdu , Arif H. Hussein
Low maternal risk perception, poor dietary practice and low adherence to iron and folate tablets among pregnant women are major contributors for higher burden of anemia. Iron deficiency anemia contribute to more than half of Anemia among pregnant women. Thus the level of maternal awareness and attitude towards dietary and other prevention practices of anemia are not well established in the study area. This study was to assess knowledge, attitude and practice of pregnant mothers towards the prevention of iron deficiency anemia in Ethiopia, 2018. Hospital based cross sectionals study was conducted on randomly selected, 128 pregnant mothers attending antenatal care service in Harar town. Data were collected by health professionals using pre tested questionnaire containing socio demographic, knowledge, attitude and practice related questions. Attitude questions were organized in five Likert scale from strongly disagree to strongly agree using positive statements. Similarly, practices were assessed in yes/no (appropriate practices were scored as yes or no otherwise). Data was analyzed using SPSS version 20 using frequency, tables, graphs and means. Pearson correlation with r was used to assess the relationship between knowledge, attitude and practice. Analysis of Variance was used to compare the mean practice by different factors. Knowledge, attitude and practice of pregnant women on preventions of IDA are not satisfactory. Thus poor practice towards prevention of IDA is the main contributing factor for high burden of anemia.

Teenage pregnancy (TP) is a recurrent global and public health problem. It poses both social and health challenges. Considering the massive campaign on the use of modern contraceptives to prevent TP in recent decades, we assessed trends in TP in Nigeria between 1961 and 2013. Pregnancy and contraception history of 70,811 women who were at least 20 years old when the Nigerian DHS was conducted in 1990, 2003, 2008, and 2013 respectively were used for the study, and descriptive statistics, time analysis techniques and multiple logistic regression were used to analyze the data at 5% significance level. The overall prevalence of TP between 1961 and 2013 was 49.5% which fluctuated insignificantly during the studied period. The TP prevalence among women who entered adulthood in 1961 was 39.2%; it peaked in 1978 at 58.9% before its unsteady decline to 39.6% in 2012, and then rose sharply to 55.6% in 2013. We predicted TP prevalence as 49.0%, 49.9% and 51.0% in 2014, 2015 and 2016 respectively. The odds of TP were over 4 times higher in the North East and 5 times higher in the North West than in the South West. Teenagers with no education had higher odds of TP and it was higher among teenagers from the poorest households (OR=5.64, 95% CI: 5.36-5.94). Rather than reducing with the worldwide acknowledged increase in contraceptive campaigns, TP increased over the years studied. As far as TP is concerned in Nigeria, the impact of the campaign on MC use is far from being effective. To achieve the objective of fewer TPs, fewer resources should be spent on access to contraception and instead diverted to areas more likely to achieve results such as improvements in educational achievement amongst girls.

Ni Putu Wulan Purnama Sari , Jintana Artsanthia
Due to increasing age, elderly are prone to non-communicable diseases (NCD), such as hypertension (HT) and diabetes mellitus (DM). Easy physical condition monitoring of people with HT and/or DM is by measuring their blood pressure (BP) and/or blood glucose level (BGL) periodically. This study aimed to compare and analyze the differences of BP and BGL among elderly with HT and/or DM in Bangkok and Surabaya. This cross-sectional study involved 100 and 96 elderly with HT and/or DM in communities of Bangkok and Surabaya respectively (n=196). There were three groups of samples which consisted of 60 DM, 68 HT, and 68 DM&HT cases. Instruments used were demography questionnaire, sphygmomanometer, and glucometer. Test of one-way ANOVA, Least Significant Difference (LSD), Kruskal-Wallis, and Mann-Whitney U were used for data analysis (α<.05). There was a significant difference of systolic and diastolic BP found between groups (p=.000 and p=.011 respectively), but no difference found between the groups of HT and DM&HT (p=.657 and p=.330 respectively). There was a significant difference of BGL found between groups (p=.002), but no difference found between the groups of HT and DM (p=.075) and between the groups of DM and DM&HT (p=.066). BP is significantly different between the group of HT and DM in term of systole and diastole, especially in elderly, but BGL is similar. The risk of being HT for elderly with DM is very high. Elderly with DM&HT have high BP and BGL similarly to those with single disease of HT or DM.

Motivation for breastfeeding and social support is very important for the success of exclusive breastfeeding. Breastfeeding support and motivation is obtained from family, leaders and the government. The implication of the government support given is the existence of regulations for organizer of public facilities that stating that the owner of public facilities must support the exclusive breastfeeding program at the airport. The airport is an important means for the mobility of both domestic and foreign tourist. The role of airport is very important to realizing healthy tourism. This study used a case study design. The subjects of this study were the leaders, staff and visitors of Adisutjipto International Airport. The number of informants is five people. The research instruments were interview guides and observation forms. Knowledge, attitudes and informant support for the exclusive breastfeeding program are good. There needs to be a stronger promotion effort for all levels of society so that exclusive breastfeeding programs can be achieved. Provision of nursery rooms at Adisutjipto International Airport is in accordance with government standards with facilities such as tables, chairs, baby boxes, washing stand, dispensers and trash can. Adisutjipto International Airport is confirmed as a breastfeeding friendly airport.

Improved reliable multilevel inverter for renewable energy systems

10.11591/ijeecs.v14.i3.pp1141-1147
Sujatha M , A.K. Parvathy
New improved multilevel inverter (MLI) topology for Renewable energy systems is proposed in this paper. Cascaded multilevel inverters (CMLI) produce an output voltage level depending on the number of individual sources connected. The main drawback of CMLI is, as the output voltage level increases in number, the switches used in the device also increases and hence the complexity of the circuit increases. As the number of switches increases, the reliability of the circuit decreases. In this paper a novel MLI topology, which employs lesser number of switches, is proposed. A simulation model of CMLI and the proposed MLI has been built in MATLAB/SIMULINK. The reliability of the CMLI and the new topology MLI is analyzed by using MIL-HDBK-217.

A new encrypted method in image steganography

10.11591/ijeecs.v14.i3.pp1412-1419
Sabyasachi Pramanik , R P Singh , Ramkrishna Ghosh
Steganography is data hiding technique in internet. Here we send CAPTCHA codes within a cover image using Image steganography. CAPTCHA are the crazy codes. They are used in human response test. The word is actually an acronym for: "Completely Automated Public Turing test to tell Computers and Humans Apart". It is a type of challenge–response test used in computing to determine whether or not the user is a human. Websites implement CAPTCHA codes into their registration processes due to spam. This is the utility of CAPTCHA codes. Here we generate CAPTCHA codes and later send them in an encrypted version. So, actually CAPTCHA codes are embedded into cover image with an encrypted form resulting stego image and thus attackers cannot fetch the actual CAPTCHA resulting in a secured transmission of confidential data using image steganography.

Predictors of post prandial glucose level in diabetic elderly

10.11591/ijphs.v8i2.19022
Ni Putu Wulan Purnama Sari , Maria Manungkalit
Post prandial glucose (PPG) level describes the speed of glucose absorption after 2 hours of macronutrient consumption. By knowing this, we could get the big picture of insulin regulation function and macronutrient metabolism in our body. In elderly, age-related slower glucose metabolism leads to diabetes mellitus (DM) in older age. This study aimed to analyze the predictors of PPG level in diabetics elderly which consist of functional status, self-care activity, sleep quality, and stress level. Cross-sectional study design was applied in this study. There were 45 diabetic elderly participated by filling in study instruments. Pearson and Spearman Rank correlation test were used in data analysis (α<.05). Results showed that most respondents were female elderly, 60-74 years old, had DM for 1-5 years with no family history, and only 33.33% respondents reported regular consumption of oral anti diabetes (OAD). Hypertension was found to be frequent comorbidity. Statistical analysis results showed that functional status, self-care activity, sleep quality, and stress level were not significantly correlated with PPG level in diabetic elderly (all p>α), therefore these variables could not be PPG level predictors. Other factors may play a more important role in predicting PPG level in diabetic elderly.

Nguyen Ngoc Son , Nguyen Duy Khanh , Tran Minh Chinh
Nonlinear systems with uncertainty and disturbance are very difficult to model using mathematic approach. Therefore, a black-box modeling approach without any prior knowledge is necessary. There are some modeling approaches have been used to develop a black box model such as fuzzy logic, neural network, and evolution algorithms. In this paper, an evolutionary neural network by combining a neural network and a modified differential evolution algorithm is applied to model a nonlinear system. The feasibility and effectiveness of the proposed modeling are tested on a piezoelectric actuator SISO system and an experimental quadruple tank MIMO system.
