Shriya Ankit Seksaria , Mini K Sheth
Diarrhoea, a major contributor of childhood morbidity and mortality is mostly caused by poor hygiene and sanitation. Literature reveal that hygiene practices at household levels greatly affects the occurrence of diarrhoea among children. A cross sectional study was conducted to determine association between hygiene knowledge and practices of mothers with occurrence of diarrhoea in young children below 3 years in the tribal villages of Gujarat. Structured questionnaire was used to elicit information on personal hygiene (PH), food Hygiene (FH), and environmental Hygiene (EH) practices of 536 mothers with children between 6-36 months of age. Past one month diarrhoeal episodes were recorded using the recall method. The mean percent scores for FH, PH and EH practices were 77%, 88% and 80% respectively. Almost 35% children suffered from diarrhoea in the past one month of which 10 were admitted to the hospital. Diarrhoeal incidences were associated with FH and EH practices (p<0.001) and not with PH practices. Improvement in the environmental and personal hygiene practices of the mothers can contribute largely in reducing the prevalence of diarrhoea among children in Chikhli taluka of Gujarat.

This research examined the lifestyles and eating habits of 42 elementary school fifth graders(20 boys and 22 girls) over a 3-day period; these children resided in theShimokita Peninsula, Aomori prefecture, which has the highest childhood obesityrate in Japan. The children’s nutritionalintakes were recorded via questionnaires and self-documented meal recorddiaries overa 3-day period (1 weekday and the weekend). The meal record diaries recorded which meals the children ate (including snacks) during the 3-day period. A regular feature of these children’s lifestyle was theviewing of at least 3 hours of television per day. Compared with the National Health and Nutrition Survey conductedby the Japanese government, the nutritionaland energy intake levels were the same but when we examined food group intakes,the vegetable intake was lower on weekends in comparison to the weekdays whenthe children were provided school lunches. In addition, salt intake exceededthe recommended standard in more than 80% of the study sample. We suggest thatthe pattern of reduced vegetable intake juxtaposed with high salt intake stemsfrom childhood and is repeated and passed down through generations; therefore, theguardians of these children require nutritional guidance and education.

10.11591/ijeecs.v12.i9.pp6732-6741
Luo Yi-Ping , Shen Ling , Cao Yi-Jia
This paper introduces a novel clustering algorithm that combines crisp and fuzzy clustering. It not only has the high accuracy of fuzzy clustering, but also reduces the dependency on initialization. Specifically, it constitutes a fast learning process and therefore, the convergence rate and the accuracy of the RBFNN are greatly improved. The simulation results show that this strategy is successfully applied to the fault diagnosis of electric power grid. The training speed and the fault-tolerance of information aberrance, which comes from the maloperation of the protections and breakers, are superior to the traditional RBFNN.

Fingerprint Classification Using Fuzzy-neural Network and Other Methods

10.11591/ijai.v3.i3.pp129-135
Idriss Tazight , Mohamed Fakir
The fingerprints are unique to each individual; they can be used as a means to distinguish one individual from another.Therefore they are used to identify a person. Fingerprint Classification is done to associate a given fingerprint to one of the existing classes, such as left loop, right loop, arch, tented arch and whorl. Classifying fingerprint images is a very complex pattern recognition problem, due to properties of intra-class diversitiesand inter-class similarities. Its objective is to reduce the responsetime and reducing the search space in an automatic identificationsystem fingerprint (AIS), in classifying fingerprints. In these papers we present a system of fingerprint classificationbased on singular characteristics for extracting feature vectorsand neural networks and fuzzy neural networks, SVM and Knearest neighbour for classifying.

Cliques-based Data Smoothing Approach for Solving Data Sparsity in Collaborative Filtering

10.11591/ijeecs.v12.i8.pp6324-6331
Yujie Yang , zhijun Zhang , Xintao Duan
Collaborative filtering (CF), as a personalized recommending technology, has been widely used in e-commerce and other many personalized recommender areas. However, it suffers from some problems, such as cold start problem, data sparsity and scalability, which reduce the recommendation accuracy and user experience. This paper aims to solve the data sparsity in CF. In the paper, cliques-based data smoothing approach is proposed to alleviate the data sparsity problem. First, users and items are divided into many cliques according to social network analysis (SNA) theory. Then, data smoothing proceeding is carried out to fill the missing ratings in user-item rating matrix based on the user and item cliques. Finally, the traditional user-based nearest neighbor recommendation algorithm is used to recommend items for users. The experiments show that the proposed approach can effectively improve the accuracy and performance on sparse data.

QR-based Channel Estimation for Orthogonal Frequency Division Multiplexing Systems

10.11591/ijeecs.v12.i8.pp6217-6223
Peilong Jiang , Honggui Deng , Bin Lei
Channel estimation is the key technology for Orthogonal Frequency Division Multiplexing (OFDM),  which has direct impact on the performance of OFDM. In this paper, we present a novel QR-based algorithm to update the channel impulse response(CIR) for DFT-based channel estimation. The discrete Fourier transform(DFT) estimation reduces the noise power that exists outside of the CIR part, because the estimated CIR from LS has most of its power concentrated on the first L samples. To reduce the noise power that exists inside of the first L samples, the CIR is further processed by QR decomposition in proposed algorithm. The simulation results show that the bit-error-rate(BER) of our estimator has reduced significantly compared with the conventional DFT-based channel estimator and LS-linear estimation.
