Application of A Self-adaption Dual Population Genetic Algorithm in Multi-objective Optimization Problems

10.12928/telkomnika.v14i1.2740
Cheng; Hunan International Economics University Zhang , Hao; Hunan International Economics University Peng
Multi-objective evolutionary algorithm is a powerful tool in resolving multi-objective optimization problems. This algorithm inherits the advantages of parallel random search, strong global searching capability and the ability to solve highly-complicated non-linear problems of evolutionary algorithm and it is usually used in the optimization problems with multiple mutual conflicts. However, such algorithms are slow in convergence and easy to be trapped in local optimal solution. This paper proposes a multi-objective dual population genetic algorithm (MODPGA) and explores the improvement strategies of multi-objective genetic algorithm. The adoption of self-adaption and dual population strategy can guarantee that the algorithm of this paper can converge to Pareto solution set in a reliable and quick manner and it can perform more extensive search on the objective function space and conduct more samples on multi-objective functions so as to be closer to the approximate optimal solution set of global optimal solutions. This solution set also includes more optimal feasible points and provides reliable basis for the decision making.

Real-Time Automatic Obstacle Detection and Alert System for Driver Assistance on Indian Roads

10.11591/ijeecs.v1.i3.pp635-646
Sachin Sharma , Dharmesh Shah
Road crashes have been a major problem in India in recent times. The occurrences have increased considerably owing to the influx of four-wheelers and two-wheelers. The interior roads connecting villages and towns have been instrumental in multiple animal-vehicle collisions. Although the figure is not too large compared to other causes of road-related injuries, they are significant in number. Though numerous efforts have been in progress to solve and reduce the number of collisions, lack of practical applications and resources along with quality analytical data (for training and testing) related to animal-vehicle collision has impeded any major breakthrough in the scenario. In our current work, we have proposed and designed a system based on histogram research including oriented gradients and boosted cascade classifiers for automatic cow detection. The method is implemented in Opencv software and tested on various video clips involving cow movements in various scenarios. The proposed system has achieved an overall efficiency of 80% in terms of cow detection. The proposed system is a low-cost, highly reliable system which can easily be implemented in automobiles for detection of cow or any other animal after proper training and testing on the highway.

Maternal and infant mortality in Ende is still high, but research related a social science is rare. The cultural aspect and medical factors such as the lack of primary health care services are also play a role. This study aims are to identifying and formulate the local cultural transformation as a way to solve maternal and infant mortality. This ethnographic research was conducted in 2013. The study carried not only interviews, but also observation towards reproductive-age women, heads of family, traditional birth attendants, doctors, midwives, local leaders, adat leaders, pastors and sisters, local government officials, and head of health district at Ende. Data is analysed phenomenologically. The strong belief to adat and local tradition has implication to people’s attitude towards traditional birth attendants. Traditional birth attendants hold superior position in the community. They also have strong influence due to their ability to massage, correctly guess infant’s sex, reposition infant in the womb, and stop bleeding during labor. Maternal and/or infant mortality has nothing to do with traditional birth attendants because local people believe that such case happens as a result of hex or black magic called ru’u. Anemia, bleeding, food taboo, and incorrect diet pattern worsen the overall condition of pregnant women. Cultural transformation is done by alternating TBAs practices in massaging pregnant women. TBAs are encouraged to massage pregnant women’s back instead of stomach since pregnant women often have to deal with low back pain during pregnancy.

In Indonesia, there are any community health volunteers called Kader. Although Kaders are members of mental health volunteer, they sometimes show negative attitude to psychotic persons, even they have already got some training about mental health. The aims of this study were to investigate 1) how is Kader's perception compare to the other countries, 2) how will they consult compare to the other countries 3) how is comparison of Kaders’ perception to mental disorder person between trained and untrained. The method of this research is a descriptive explorative using survey study. This study was held on June to September 2013. It was conducted in five districts of Yogyakarta area with 619 respondents. The Questionnaires used contained three sections are follows; Part A is about Demographic Data, Part B two case vignettes (taken from MacArthur Health Module of the 1996 general Social Survey) and Part C about Kaders experiences. The perception of Kader as part of the community is lower than the general residence in the United States and Japan. The comparison between trained and untrained Kaders shown that trained Kaders has better perception toward patient with mental disorder. These results suggest that actual experiences in meeting the cases contributed to the improvement of Kaders’ perception better than the previous mental health training did. It might be Kaders with short experience are explored information Kaders should be trained with more structured curriculum and recruiting Kader is recommended to recruit the young generation.

Effective utilization of family planning services are major contributors of improved maternal health. This, in turn, needs adequate involvement of male partners through direct uptake the services and approval of the spouses’ usage. Yet the family planning method utilization as well as male involvement is indicated to be low in Ethiopia. Qualitative case study was conducted in August 2015 in Arba Minch town to identify barriers to male involvement in uptake of family planning services. Open ended, semi-structured questionnaire was used to interview the participants. Four men and four women are purposively selected. Interviews were conducted in audibly private location after verbal consent was obtained from the recruited individuals. All interviews were recorded and transcribed verbatim. The narratives were then translated to English and the responses are aggregated in to nine concepts. The final aggregated data were analyzed using OpenCode 3.4 software based on thematic framework analysis. Total of eight participants (four men and four women) were interviewed where seven are married and one is single. Participants identified that, Perception (or opinion) towards family planning as women’s issue, Sex preference for inheritance and considering children as measure of blessing of and Fear of partner sexual promiscuity and to reduce women’s attractiveness were barriers for male involvement in modern family  planning method. Future interventions aimed at improving family planning services and methods utilization in Arba Minch town and similar settings need to consider these bottlenecks for male involvement.

The farmers in Indonesia have not maximally taken advantage of the existence of rice husk; therefore the huge number of the husk becomes disturbing waste, which spoils environment. The waste of rice husk is potentially capable of improving the farmers’ economy amidst the people’s lack of knowledge about its potential to commercially produce charcoal briquettes from it, make it a plant growing medium, and change it into manure. This research aims at knowing if the training of recycling waste of rice husk can improve the farmers’ entrepreneurship motivation. The subjects of the research were farmers in groups at Bimomartani village, Ngemplak district, Sleman regency. They were 60 participants divided into experintal and control groups. The planned experiment used untreated control group design with dependent pretest and posttest samples. The paired sample t-test and independent sample t-test were used as the techniques of analysis in this research. The result of t-test on paired sample t-test for the experimental group resulted in the value of t = -6.659 with p = 0.000 (p<0.01), which means there was a significant difference of entrepreneurship motivation before and after the training of recycling rice husk. The analysis for Independent sample t-test resulted in the value of t = 7.411 with p = 0.000 (p<0.01), which means there was a significant difference of entrepreneurship motivation between experimental and control groups. It can be concluded that the training of recycling waste of rice husk was effective in improving the farmers’ entrepreneurship motivation.

10.11591/ijeecs.v1.i3.pp597-606
Ahmed Y. F. Al_Sahlani , Songfeng Lu
Authentication takes its place to grant authorized user a remote access to certain online resources. As well, prevent unauthorized user from accessing that resources. Unforyunatly most of authentication schemes consider only security factors without taking in consideration the communication resources required. Recently, Li et. al. proposed an enhanced smart card based remote user password authentication scheme. We analyzed their scheme and we pointed out that, their scheme required high communication overhead. Furthermore, their scheme suffer from forgery, user impersonation and server impersonation attacks. Through this paper to address aforesaid weaknesses, we propose a Lightweight communication overhead authentication scheme using smart card. The security and performance analysis shows that, our proposed scheme is lightweight communication and computation cost as well secure and can withstand wide spectrum of malicious attacks, like forgery, insider, replay and stolen smart card attack. Besides, our scheme encompasses desired security attributes. Therefore, it is suitable for practical use compared to other related scheme.

10.11591/ijphs.v5i1.4758
Oryzati Hilman Agrimon , Jackie Street
Diabetes education is a key factor for a successful diabetes care. Comprehensive diabetes education materials for conducting structured diabetes education programs were rarely found in primary care setting in Indonesia. There was a need for developing new, comprehensive diabetes education materials for low-literate readers. Developing these education materials followed standard steps in developing print materials, and took account tips for writing low literacy materials for poor readers. The new diabetes education materials consisted of ten various leaflets, also printed as14 posters and 14 x-banners. The ten diabetes leaflets were pre-tested to 5 people with type 2 diabetes (T2D). After minor revisions, the leaflets were printed and distributed to 88 people with T2D attending two structured diabetes education programs in Yogyakarta City. These 88 people were requested to evaluate the leaflets using an evaluation form consisting of four items on language usage, font size,  use of pictures, and diabetes information with a 1-10 rating scale; and an open-ended question for improvement. Descriptive statistics were used to analyze the results. Most participants thought that the leaflets were easy to understand and read, interesting, and simple. Majority of participants (79.7%) gave favorable comments without providing suggestions for improvement, such as: “The diabetes leaflets are already good and easy to understand” One third of the participants gave suggestions for improvement. The comprehensive diabetes leaflets developed were well received and highly appreciated by people with T2D attending diabetes education programs.
