With the rapid development of computer science and technology, network attack and defense has become an important research topic in the field of information security. Teaching on network attack and defense technology in universities and research institutions has a very strong experimental characteristic, but due to the special nature and the destructive characteristic of network attack and defense technology, it is difficult to carry out experiments. In this paper, we designed and implemented a parallel and distributed network security experiments platform on which experiments can be carried out through a web interface and network simulation scripts. We believe that it is also an excellent platform for teaching courses in operating systems and networking. The results of experiments in this paper show that the platform could provide the laboratory personnels with independent experimental environment, perfect experimental control functions, excellent data collection and analysis services, etc. DOI: http://dx.doi.org/10.11591/telkomnika.v11i6.2666

Wireless sensor networks have profound effects on many application fields like security management which need an immediate, fast and energy efficient route. In this paper, we define a fault-tolerant and QoS based network layer for security management of chemical products warehouse which can be classified as real-time and mission critical application. This application generate routine data packets and alert packets caused by unusual events which need a high reliability, short end to end delay and low packet loss rate constraints. After each node compute his hop count and build his neighbors table in the initialization phase, packets can be routed to the sink. We use FELGossiping protocol for routine data packets and node-disjoint multipath routing protocol for alert packets. Furthermore, we utilize the information gathering phase of FELGossiping to update the neighbors table and detect the failed nodes, and we adapt the network topology changes by rerun the initialization phase when chemical units were added or removed from the warehouse. Analysis shows that the network layer is energy efficient and can meet the QoS constraints of unusual events packets.

Study of Social Integrity Behavioral Mode Based On Multi-agent System

https://ijeecs.iaescore.com/index.php/IJEECS/article/view/2332
Yu Wang , Haiyang Wang , Yadi Wang , Xin Gu
Social integrity deficiency has become the main obstacle and prominent bottleneck to the construction of a harmonious society. Under this serious circumstance, paying attention to the problem and finding a solution has become an important issue we are faced with contemporarily. Former studies by some scholars have mainly centered on the basis of regime and education and some conclusions have been made. This paper, from the perspective of Multi-agent system, analyses the behavioral mode of the social integrity system and describes the process of emergence from the micro level to the macro one. Based on the Multi-agent system stimulus-response principle, it constructs the basic behavioral mode of social integrity; based on the adaptive-learning theory, it constructs the whole behavioral mode; and based on the evolution of agent, it constructs the level-emerge mode, which will provide a new point of view for the research of the social integrity system. According to this, some resolutions can be achieved to the issue mentioned above, which builds scientific reasonable policy basis and gives theoretical guidance for the central and local government in solving the widespread lack of social integrity. DOI: http://dx.doi.org/10.11591/telkomnika.v11i6.2645

Way of walking is a spatio-temporal phenomenon that typifies the motion characteristics of human. In this paper, we propose a human gender identification method based on the outdoor surveillance of human gait using statistical techniques and geometrical function applied to three-dimensional (3D) joint movement data. The statistical techniques are used to define the features of the joint of the human gait, and the geometrical function applied for gender recognition. Our proposed scheme is based on extraction of the concern joint (hip joint) data that provides plentiful information for gender recognition. Here the rotation angle data of a hip joint were computed from the Biovision Hierarchical data (BVH file). The use of BVH file for human gender recognition is a novel feature of our work. The results indicated that the proposed approach is highly reliable for gender recognition. DOI: http://dx.doi.org/10.11591/telkomnika.v11i6.2274

The aim of this study is to explore the sources of job stress and type of coping among academic staff from two countries; namely Pahang, Malaysia and Yogyakarta, Indonesia. This study used qualitative design, and phenomenology technique  conducted to analyze the data. Twenty two academic staffs were involved in this study. The result found several interesting findings. Seven stressors categories were found; (1) inadequate role occupancy, (2) increasing work demands, (3) deficient role preparedness, (4) insufficient role support, (5) role ambiguity, (6) role conflict and (7) work-family conflict. There were four responses of stress that was showed by university academic staffs, namely: (1) behavioral responses, (2) emotional responses, (3) cognitive responses, and (4) physiological responses. The reason that lead respondents still continue work as academic staff are (1) being a lecturer was the choice of his/her life, (2) teaching was noble work, (3) could share knowledge with others/students, (4) love the profession as a lecturer, and (5) feel happy to teach and discuss with students. The coping strategy that always used  by academic staffs  to cope with job related stress were five coping strategy patterns, namely: (1) problem focused coping, (2) emotion focused coping, (3) seeking social support, (4) using religious coping, and (5) making meaning.DOI: http://dx.doi.org/10.11591/ijphs.v2i2.2427

Object Descriptor Combining Color and Detection

https://ijeecs.iaescore.com/index.php/IJEECS/article/view/2327
Yun Gao , Guo-wu Yuan , Hao Zhou , Xue-jie Zhang
Object descriptor has become one of the key factors for a robust and accurate tracker. In this paper, we propose an object descriptor combining color information and motion detection. A tracked object can be described by its hue histogram excluding the background pixels around the tracked object for restraining the disturbing of complex background environments. During the tracking process, we model the object descriptor by Gaussian Mixture Model for adapting the appearance variation of the tracked object. Tracking experiments in the frame of particle filter show that our proposed object descriptor can effectively improve the robustness and accuracy of object tracking under the situations of complex environments and appearance variations. DOI: http://dx.doi.org/10.11591/telkomnika.v11i6.2616

Dengue Knowledge and Preventive Practices among Rural Residents in Samar Province, Philippines

https://ijphs.iaescore.com/index.php/IJPHS/article/view/4601
Leodoro Jabien Labrague , Begonia C Yboa
The World Health Organization (WHO) classifies dengue as a diseaseimportant in public health. The epidemiology and ecology of dengueinfections are strongly associated with human habits and activities. Thepresent study aimed to evaluate the knowledge and practices regardingdengue infections among rural residents in Samar Province, Philippines. Across sectional design was adopted for this investigation A conveniencesamples of six hundred forty six (646) residents who were visiting the ruralhealth units in different municipalities of Samar, Philippines were taken asparticipants in study. More than half of the respondents had good knowledge(61.45%) on causes, signs and symptoms, mode of transmission, andpreventive measures about dengue. More than half of the respondents useddengue preventive measures such as fans (n = 340, 52.63%) , mosquito coil(n = 458, 70.90%), and bed nets (n = 387, 59.91%) to reduce mosquitoeswhile only about one third utilized insecticides sprays (n = 204, 31.58%) andscreen windows (n = 233, 36.07%) and a little portion used professional pestcontrol (n = 146, 22.60%). There was no correlation between knowledgeabout dengue and preventive practices (p=0.75). Television/Radio was citedas the main source of information on dengue infections. Findings suggest thatbetter knowledge does not necessarily lead to better practice of denguemeasures. Educational campaigns should give more emphasis on costeffective ways of reducing mosquito and preventing dengue such asenvironmental measures and control. Furthermore, wide range ofinformation, skills and support must be provided by the government toincrease dengue awareness among residents. DOI: http://dx.doi.org/10.11591/ijphs.v2i2.2511

https://ijeecs.iaescore.com/index.php/IJEECS/article/view/2307
Xuesong Yan , Qinghua Wu , Hammin Liu
In this paper, aim at the disadvantages of standard Particle Swarm Optimization (PSO) algorithm like being trapped easily into a local optimum, we improves the standard PSO and proposes a new algorithm to solve the overcomes of the standard PSO. The new algorithm keeps not only the fast convergence speed characteristic of PSO, but effectively improves the capability of global searching as well. Experiment results reveal that the proposed algorithm can find better solutions when compared to the standard particle swarm optimization algorithm. We use the proposed algorithm for digital circuit optimization design, and the final circuit is optimized in terms of complexity (with the minimum number of gates). DOI: http://dx.doi.org/10.11591/telkomnika.v11i6.2135

https://ijphs.iaescore.com/index.php/IJPHS/article/view/4602
Jemy Joseph
The neonatal unit frequently occupied by newborns that are marginally viable or critically unwell and could be considered as terminally ill. It is a busy, highly technical environment with advanced life saving medical equipments, at its disposal. The technology has had a profound effect on neonatal nursing practice. The escalation of technology and medical advances has been followed by an increase in later disabilities. Many devices have altered from being one of the supporting clinical practices to that of being an essential requirement in treatment delivery. Even after the use of all settings.  Some newborns will die in the NICU. The mortality and morbidity rate is still high. This has given rise to many ethical issues including withdrawal of intensive care therapies. The conceptual framework for the study is based on Health Belief Model. Health Beliefs are person’s knowledge, ideas and attitude, about health and illness. In this study various literature was reviewed which includes, the research design selected for the study was Descriptive research design. The dependent variable and independent variable were selected for the research.DOI: http://dx.doi.org/10.11591/ijphs.v2i2.2779
