Interface is a medium or channel to communicate between human and things, while interaction is the manner of communication between them. Interaction design is designing experience of user through the interaction process for human, thing, system, and space. Richard Buchanan suggests four kinds of interaction: interface (person to thing interaction), transaction (person to person interaction), human interaction (human and environment interaction) and participation (human to cosmos interaction). With digital technology, architecture and space design have made various experiments at form, function, and content of space. Space evolves from a physical container to a stage to provide narrative and create new experience to users. Since understanding users, creating experience, efficient space design, content planning, and applicable technology are required for interaction design in space, multi-disciplinary research and cooperation is needed.

E-learning is a new teaching model nowadays, and Virtual Reality (VR) technology is reported that the use of virtual reality as an education tool can increase student interests, understanding, and creative learning because of encouraging students to learn by exploring and interacting with the information on the virtual environment. Besides that, LEGOs have long been the favorite of many children. LEGOs provide a mechanism to understand and do for many concepts from spatial relationships to robotics platforms. In this paper, we present a virtual reality application based on the assembly of LEGO-Like bricks to increase math and science learning by improving spatial thinking. It not only encourages students to pursue careers in science, technology, engineering, or mathematics but also enhances learner's ability to analyze and solve problems. The application is built by Processing 2.0 as the easier programming language which is a top-down approach to build the 3D interactive program.

The introduction of chlorpromazine in the 1950's revolutionized the treatment of schizophrenia and ultimately led to the development of selective $D_2$ antagonists such as haloperidol, a goal in keeping with the prevalent theories at that time. However, limitations in the efficacy of these agents, a growing awareness of their side effects, and theoretical shifts in our understanding of schizophrenia have encouraged ongoing efforts to develop better 'atypical' antipsychotics. Clozapine, and subsequently risperidone, represent examples of these novel compounds, both of which incorporate shared serotonin-dopamine antagonism(SDA). The next years will be dominated by further development of SDA compounds, although a number of other lines of investigation are also being pursued.

There is a growing trend for asset intensive industries to outsource maintenance services of their complex assets since outsourcing through service contract reduces upfront investments in infrastructure, expertise and specialised maintenance facilities. Estimation of costs for such contracts is complex and it is important to the user and the service providers for economic variability. The service provider's profit is influenced by many factors such as the terms of the contract, reliability of asset, and the servicing strategies, costs of resources needed to carryout maintenance. There is a need to develop mathematical models for understanding future costs to build it into the contract price. Three policies for service contracts are proposed in this paper considering the concepts of outsourcing maintenance service of assets to the service providers. Conceptual models are developed for estimating servicing costs of outsourcing through service contracts by considering time dependent failure mode.

Railway route maps including subways is a guide map which offers transport information as well as cartographic diagrams and is not only a way of communication, but it should give also concrete image and pleasing form. The elements of route map should meet satisfaction requirement condition and design attributes with aesthetic principles. To guide passengers by giving geographic information effectively, we need to understanding the following concepts and its application of basic elements such as expressing its structure and value. Therefore it should appear as a diagram with typography, form, symbols and colour. This means the aim of a good visualization should be done by a method that is concrete and a synthesis of well composed elements.

Method: We reviewed the papers of communication analysis studies in various fields and summarized communication error researches. Results: We proposed perspectives for communication error analysis and explained the need for extended analysis framework using advanced human-machine interfaces, which will cause the change of communication between operation team, including shifted abstraction phenomena. And we describe main concepts and the case study of H-H-S framework and finally introduce current studies of communication analysis in nuclear domain. Conclusion: The goal of communication analysis is common in all industries. We have to share and co-work for event prevention. Application: The results of the communication analysis might help to facilitate the understanding for interested researchers.

The purpose of this study is to analyze the influence of the flow concepts to the visitor's satisfaction in the mobile sensor-network navigation system. recently installed in the National Museum of Korea in Seoul. The satisfaction of visitor's on the facilities and services offered by the museum environment is crucial in that it provides a value-added learning experience for the visitor to immerse into the historical descriptions and cultural contents, often presented in digital formats. 200 subjects' data are analyzed using the structural equation model and the key results are presented. It is hoped thai our flow results show a new way of understanding of information technologies applied to the museum setting.

This study compared the effectiveness of various prevention methods(1-time video viewing; repeated video viewing; participation-enriched video viewing) used in delivering awareness of sexual abuse and coping skills to preschool children. All of the experimental groups performed better than the control group. The participation-enriched viewing group displayed higher levels of coping skills than the control and the 1-time viewing groups. Repeated viewing and participation-enriched viewing approaches were most effective in long-term understanding. The repeated viewing group showed superiority in long-term coping skills. Direct participation, interaction, and reinforcement by means of repetition are important for optimal results in sexual abuse prevention education.

There is mounting evidence that complex computer system displays in control rooms contribute to cognitive complexity and, thus, to the probability of human error. Research shows that reaction time increases and response accuracy decreases as the number of elements in the display screen increase. However, in terms of supporting the control room operator, approaches focusing on addressing display complexity solely in terms of information density and its location and patterning, will fall short of delivering a properly designed interface. This paper argues that information complexity and semantic complexity are mandatory components when considering display complexity and that the addition of these concepts assists in understanding and resolving differences between designers and the preferences and performance of operators. This paper concludes that a number of simplified methods, when combined, can be used to estimate the impact that a particular display may have on the operator's ability to perform a function accurately and effectively. We present a mixed qualitative and quantitative approach and a method for complexity estimation.

Understanding of 'spatial' pressure distribution is required to determine design loads on local structures, such as plating and framing. However, obtaining a practical 'spatial' pressure distribution is a hard task due to the sensitivity of the data acquisition frequency and resolution. High-resolution Pessure-Idicating Flm (PIF) was applied to obtain pressure distribution and pressure magnitude using stepped crushing method. Different types of PIF were stacked at each test to creating a pressure distribution plot at specific time steps. Two different concepts of plotting 'spatial' pressure-area curve was introduced and evaluated. Diverse unit pixel size was chosen to investigate the effect of the resolution in data analysis. Activated area was not significantly affected by unit pixel size; however, total force was highly sensitive.
