Metode ABA (Applied Behaviour Analysis) : Kemampuan Bersosialisasi Terhadap Kemampuan Interaksi Sosial Anak Autis

Autism is a complex development disorder attributed with communication, social interaction, and imagination activity. Disturbance of social interaction on autism could affect learning and behaviour aspects. The study aimed to analyze the influence of applied behaviour analysis method: social ability on autism children's social interaction ability. The study used pre experimental design with one group pretest posttest without control group design. The sample was 15 children, with using total sampling. Data was analyzed with Wilcoxon Match Pair Test. The result showed majority autism children (66,7%) had a less ability of social interaction before intervention (pre test), and majority autism children (53,3%) had enough ability of social interaction after intervention (post test). Data analyzed showed that P value was 0,008 (0,008 p≤0,05). It can be concluded that there is an influence of applied behaviour analysis method: social ability on autism children's social interaction ability, it is suggested for the family with an autism child to give applied behaviour analysis method: social ability to exercise the autism children's social interaction ability

Development of predicting model for safety behaviour based on safety psychology and working environment

The increasing trend of occupational accident due to unsafe act and unsafe condition especially in construction site suggests the need for more proactive safety assessment model. Therefore this research aimed to establish a prediction model of safety behaviour based on safety psychology and working environment factors in construction site. Theory of Planned Behaviour (TpB) was adapted to examine on the prediction model of safety behaviour among construction workers using safety psychology representing unsafe act and working environment factors representing unsafe condition. A modified perception questionnaire named Safety Psychometric Model (SPM) was proposed based on TpB questionnaire and safety attitude questionnaire (SQA). Previously, the approach has successfully applied in health care and manufacturing sector. The questionnaire has been validated by three industrial and academic experts. A total of 554 respondents among 92 construction site were selected as the subjects for analysis. Structural Equation Modelling (SEM) and Statistical Package for the Social Science (SPSS) was use for analysis purpose which involve correlation, regression and structural equation analysis. The results demonstrated that safety psychology and work environment factor was related positively with safety behaviour intention. The elements of workers’ attitude, subjective norm and perceived control that form the safety psychology context found to be significantly has the ability to predict safety behaviour. The demographics variances of personal and education background, working experiences and training background also determine as the factors of safety behaviour of the construction workers. The research also successfully established a safety behaviour prediction model that named Safety Psychometric Model. The model can be benefited by safety practitioners, organizations and researchers to explore the safety behaviour prediction. It also enhanced the knowledge in the area of employee behaviour prediction and modelling

Simulation of human movement and behaviour in crowded spaces using gaming software

This paper discusses the development of human movement and behaviour simulation in crowded spaces as part of the AUNT-SUE (Accessibility and User Needs in Transport for Sustainable Urban Environments) research project. The research starts with applying a video observational method to understand human movement and behaviour in crowded spaces in the real world. Six hours of video were recorded at a multi-mode transportation system and almost 19,000 individual human movements and behaviours were analyzed. Six types of behaviour were derived from the three major movements of free, opposite and same direction. Six factors affecting human movement and behaviour were recognized from the video analysis. The DarkBASIC Professional gaming software was used to simulate the human movement and behaviour in the virtual world. The six factors affecting human movement and behaviour were considered as the parameters for the virtual humans. Case studies considering multi-mode transportation systems, bottleneck and non-bottleneck situations were applied to validate the prototype software system

Analysis of a duffing oscillator that exhibits hysteresis with varying excitation frequency and amplitude

Hysteresis, or jump phenomenon, are a common and severe nonlinear behaviour associated with the Duffing oscillator and the multi-valued properties of the response solution. Jump phenomenon can be induced by either varying the amplitude or the frequency of excitation. In this paper a new time and frequency domain analysis is applied to this class of system based on the response curve and the response spectrum map

Time scale synchronization of chaotic oscillators

This paper presents the result of the investigation of chaotic oscillator synchronization. A new approach for detecting of synchronized behaviour of chaotic oscillators has been proposed. This approach is based on the analysis of different time scales in the time series generated by the coupled chaotic oscillators. This approach has been applied for the coupled Rossler and Lorenz systems.Comment: 19 pages, 12 figure

Application of continuum laws in discontinuity analysis based on a regularised displacement jump

The application of continuum constitutive laws in embedded strong discontinuity analysis is examined. By adopting a regularised discontinuity (approximating the unbounded strain field resulting from a displacement jump with a bounded function), the strain field in a body is always bounded, hence continuum laws can be applied. However, this must be done with some caution since the ‘fictitious’ strain state at the discontinuity can lead to spurious behaviour that does not arise in the conventional application of classical constitutive laws. Particularly addressed is stress locking as a function of the displacement regularisation in some plasticity models. It is also shown that the regularisation function can have a serious impact on convergence behaviour for some types of constitutive models
