Smart Grid (SG) provides enhancement to existing grids with two-way communication between the utility, sensors, and consumers, by deploying smart sensors to monitor and manage power consumption. However due to the vulnerability of SG, secure component authenticity necessitates robust authentication approaches relative to limited resource availability (i.e. in terms of memory and computational power). SG communication entails optimum efficiency of authentication approaches to avoid any extraneous burden. This systematic review analyses 27 papers on SG authentication techniques and their effectiveness in mitigating certain attacks. This provides a basis for the design and use of optimized SG authentication approaches.

Abdu Oumer Abdu , Berhanu Abebaw Mekonnen
Dietary diversity (DD) is a validated proxy indicator of micronutrient adequacy among different age groups including infants, children and women. This study assessed level of dietary adequacy and its associated factors among school age children in Guraghe Zone, Ethiopia. Survey was conducted among 769 children aged 6 to 12 years of with their care givers using multistage sampling method. Data were collected by using structured questionnaire containing the ten food groups for minimum dietary diversity for women and other parts. Adequate dietary diversity was categorized those children who consume at least five food groups. Bivariate and multivariable binary logistic regression with odds ratios (95% CI) was computed. Overall 769 children were included in the study, with a mean age of 8 years. The mean dietary diversity score was 4.9 (±1.42). About 444 (58.3%) had an inadequate dietary diversity. Those children from extended family size had 1.3 times to have inadequate DD level (AOR=1.3). Children from female headed households, did not attend formal education had 1.3 and 1.4 times higher odds of having an inadequate DD level (AOR=1.3 and 1.4). Similarly, children living with uneducated caregiver had six fold more likely to have an adequate DD level (AOR=6.7). The dietary diversity of children in the study area was below average. Household head, caregiver’s educational status, occupation of the household head, father/female headed household and family size were found to be associated with DD score. There should be awareness creation through existing Health extension platform and back yard vegetation should be improved.

Toward semantic similarity measure between concepts in an ontology

10.11591/ijeecs.v14.i3.pp1356-1372
Suwan Tongphu , Boontawee Suntisrivaraporn , Pakinee Aimmanee
A similarity measure is one classical problem in Description Logic which aims at identifying the similarity between concepts in an ontology. Finding a hierarchy distance among concepts in an ontology is one popular technique. However, one major drawback of such a technique is that it usually ignores a concept definition analysis. This work introduces a new method for similarity measure. The proposed system semantically analyzes structures of two concept descriptions and then computes the similarity score based on the number of shared features. The efficiency of the proposed algorithm is measured by means of the satisfaction of desirable properties and intensive experiments on the Snomed ct ontology.

Lifetime enhancement for clustering protocols in heterogeneous wireless sensor networks

10.11591/ijeecs.v14.i3.pp1305-1314
Basim Abood , Yasser Kareem Al-Rikabi
In this paper, we propose a new clustering method called fuzzy stable election protocol (FSEP), which is capable to overcome the bottleneck problem and addressing the uneven energy consumption problem in heterogeneous WSNs. We also propose an energy-efficient routing method called particle swarm optimization routing method (PSORM) to find the optimal routing path for the heterogeneous WSNs. PSORM seeks to investigate the problems of balancing energy consumption and maximization of network lifetime. To demonstrate the effectiveness of FSEP-PSORM in terms of lessening end-to-end delay, balancing energy consumption, and maximization of heterogeneous network lifetime, we compare our method with three approaches namely, chessboard clustering approach, PEGASIS, and LEACH. Simulation results show that the network lifetime achieved by FSEP-PSORM could be increased by nearly 38%, 45%, and 60% more than that obtained by PEGASIS, LEACH and stable election protocol clustering (SEP), respectively.

Findings from a synthesis of technical assistance models and frameworks were used to code the use of 25 core elements of technical assistance in studies and evaluations of implementation interventions to affect program, organization, and systems change. The 25 core elements were group into five components: preparation for the provision of technical assistance, development of a technical assistance plan, implementation of technical assistance, evaluation of the effects of technical assistance, and sustainability of technical assistance-facilitated changes. Results indicated that a subset of 11 core elements was related to between groups and between condition differences in the sizes of effect for program, organization, and systems changes. Results also showed that more intensive technical assistance was associated with larger sizes of effects compared to less intensive technical assistance and that particular combinations of practices were associated with the largest sizes of effect.

Bio-physicochemical markers of the Aedes aegypti breeding water in endemic and non-endemic area

10.11591/ijphs.v8i2.18883
Nurul Hidayah , Dwi Rahmawati
The survival of Aedes aegypti larvae is inseparable from the adequacy of food, including organic substances available in the breeding water. It is very dependent on the level of water markers such as temperature, salinity, Dissolved Oxygen, and pH. The study used quantitative observational analytic with a case-control study design. Case group has consisted of breeding water in endemic area and control group was in non-endemic area. The sample size was 43 samples for each group, collected by purposive sampling technique. Data were analyzed by Chi-square and Mann-Whitney test. Larvae mostly presence in endemic area (68.3%) and mostly absent in non-endemic area (85.4%) (p-value = 0.002). Temperature in endemic area mostly in 27-30oC (86%) and non-endemic area mostly in <27oC or >30oC (72.1%) (p-value = 0.000). Salinity in endemic and non-endemic areas has no difference (p-value = 0.266). DO in endemic areas were mostly in 5.02-7.82 mg/l (76.7%). While DO in non-endemic area was mostly in <5.02 mg/l or >7.82 mg/l (95.3%) (p-value = 0.001). The pH <6 or >7.8 is mostly in non-endemic areas (87.8%) and pH 6-7.8 is mostly in endemic areas (63.4%) (p-value = 0.000). Bio-physicochemical markers of breeding sites water have differences between endemic and non-endemic area except salinity. The temperature, salinity, DO, and pH affected the presence of larvae and the most affected is DO marker. While the marker that affected the presence of larvae in the non-endemic area is pH.

Diabetes is a chronic disease that requires regular and sustainable health management that involves proper treatment. Some diabetic patients use CAM, as well as conventional medicine, to maintain their health and control their blood sugar. This literature review aimed to 1) determine the prevalence of CAM used by patients with diabetes, summarize and evaluate the CAM use that includes: characteristics, patterns, types and reasons, 2) propose a conceptual model associated with CAM used by patients with diabetes. Systematic reviews were searched using an electronic database. The systematic reviews were published between 2005 and 2015 by using specific keywords. The number of systematic reviews obtained as a search result is 14 articles from 14 countries. The prevalence of CAM used by patients with diabetes ranged from 16.6% to 76%. Determinants associated with the CAM use were age, gender, family income, occupation, residence, and the characteristics of the disease, such as the length of time since diagnosed and complications. Most patients used CAM, along with the conventional treatment, and did not inform health professionals about the CAM use. The CAM use by patients with diabetes was relatively high and the confidence of patients believed the benefits of CAM. Therefore, integration with health professionals to develop CAM management is highly required.

Teacher and student interactions and characteristics from critical theorists school

10.11591/ijere.v8i2.17926
Akbar Salehi
In recent years, critical thinkers have done serious discussions in education and other fields in our lives like social, cultural, political and economical. This paper is going to consider some of the critical thinkers’ theories in order to clarify teacher and student interactions in education. The research is a type of fundamental and qualitative study which frames teacher and student interactions by means of a descriptive – analytical method. Accordingly, we introduce critical teacher as a teacher who includes specific characteristics like emancipation, critical nature and openness. Therefore mentioned teacher attends the role of culture in human life and he resists reproduced by the regime. He is someone who provides the way for public hearing; in addition, he teaches his students how to resist domination. On the other side, a student in this school will not be dominated by the regime by means of its essential tools as probe and questioning. A student has been taught to hear everyone regardless of race, religion and social class. Finally, this paper proposes applying these ideas for educational systems informal and operational ways.

Immunization coverage in every city/regency must be conducted in accordance with the standard coverage to suppress infectious diseases that can be prevented by vaccination. Temanggung regency is one of the cities/regencies in Central Java Province that have not reached 100% of village universal coverage immunization (UCI). The aim of this study was to determine the coverage of complete basic immunization in infants in Temanggung regency. The design of this study was descriptive observational with quantitative and qualitative approaches. The respondents of the research were parents having babies and the sample size was 520 children. The instrument used was the Rapid Card Check Form recommended by UNICEF. The results showed that there were still infants who had not been immunized. The reasons were that the infants had low birth weight, sick children during immunization, and no support from parents. As the immunization program aims to reduce infant and child mortality, parental awareness is important to increase immunization coverage in Temanggung regency.

Cigarette smoke contains 7, 12 dimethylbenzanthracene (DMBA). Metabolic of DMBA is immunosuppressive. Black cumin seed oil (BCSO) is an immunomodulation. The aim of this study was to determine the effect of BCSO on leukocyte, CD4Th and CD4CD25Treg in Sprague-Dawley (SD) mice induced with DMBA. The 96 SD rats were divided into 8 groups of 12. Group I received aquabidest and standard feeding. Groups II, III and IV received BCSO (an equivalent of 6.8, 68 and 136 mg/kg BW / day thymoquinone, respectively). Group V received thymoquinone (50 mg / kg BW / day) and group VI received tamoxifen (60 mg / kg BW). Group VII (DMBA) was induced with DMBA (10x20mg / kg BW for 5 weeks). Group VIII received standard feeding and corn oil treatment. In the third week, all groups began to be induced with DMBA (20 mg/kg BW twice per week for five weeks). Data collection of leukocytes, CD4Th and CD4CD25Treg was performed at week 27th. The mean difference of CD4Th and CD4CD25Treg counts between groups was calculated with one way ANOVA. Results: The administration of BCSO, thymoquinone, and tamoxifen had increased leukocytes and CD4 Th cell count. The CD4Th cell count of the treatment groups was higher than that of the DMBA group (p <0.05). BCSO equivalent doses of 6.8 and 68 mg/kg BW / day thymoquinone showed immunoprotective effects. Conclusion: It can be concluded that the BCSO administration at doses of 6.8 and 68 mg/kg BW / day shows immunoprotective effects due to DMBA induction.

Abdu Oumer
Despite great efforts against foodborne diseases, the occurrence of these problems remains a significant health issue in both developed and developing countries. This study was to assess determinants of food safety practice among food handlers in selected food establishments in Dire Dawa City administration, in 2017. Cross sectional survey was conducted among 356 food handlers from the selected food establishments in different categories. The CODEX food safety questionnaire was used to assess food safety knowledge (23 questions), attitude (six questions) and practice using interview and observation checklists (15 points). Satisfactory practice was defined as those who practice 70% of food safety measures correctly. Frequency, percentage, mean, binary logistic regression with a crude odds ratio and adjusted odds ratio (AOR) at 95% confidence interval were calculated. Out of the total study subjects, 354 food handlers participated in this study with 99.4% response rate. A total of 191 food handlers, 54.0% were female with overall mean age of 29.5 years. About 129 (36.4%), 194 (54.8%) and 106 (29.9%) had adequate knowledge, positive attitude and satisfactory food safety practice. Having food safety training (AOR= 2.0), with adequate knowledge (AOR = 2.83), positive attitude (AOR= 2.09), presence of food safety guideline (AOR = 2.23) and supervision (AOR= 2.07) were significant predictors of satisfactory food safety practices. In general food safety/hygienic practices of food handlers was found to be low. Having adequate knowledge, positive attitude, presence of food safety guideline and formal food safety training were significant predictors of food safety practices among food handlers.

Sun drying is a conventional drying method of paddy commonly used in Asia. During the process, grains are mixed and turned continuously using a rake to maintain good quality. For this reason, a robotic rake or Rakebot was developed in this study to properly mix the grains during sun drying. Rakebot is manually controlled using a mobile application through Bluetooth connection but can also move automatically using the previous movements that were recorded on the first used. It was developed using a microcontroller that gives directions to the motors based on the received instructions from the mobile application. The recorded movements are saved in a memory card by means of a memory card module connected to the microcontroller. The objective measures showed that the Rakebot ensures simultaneous reduction of the moisture content of paddy. Also, the rake design of the robot prevents fissuring of grains.

Amil Kusain Tan
It is evident in the literature that as near end of life approaches, health expenditure increases. The rehospitalization and underutilization of palliative and hospice services add to the burgeoning health cost. There is a lack of support for patients with advanced illness in long-term care facilities. This paper aims to provide a comprehensive review of the problem and assess alternatives to reduce readmission among patients with advanced disease and those who are at the end of life.  This paper adapted Bardach’s Eightfold Path analysis as a guide to analyzing the problem using a case study approach. The article discussed the issues, reviewed the literature for evidence, provided the alternatives, identified criteria, evaluated projected outcomes, discussed the trade-offs of adopting the policy, and provided a recommendation. In conclusion, integration of palliative and hospice care services across the continuum of long-term care is a viable alternative policy to address the problem.
