Recently, smart phones are widely used and as the phone sensors are evolved, we can get more various kinds of data from them. Using the data, many researchers take an effort to aware user's situation and the context-awareness for smart phones are actively applied to the real-world applications. However, to make an advanced information from sensing data need complex processing and analyzing information. Some of these computing processes are fully handled on smart phone or some data are processed by transferring to server. In this paper, we proposed a method for reducing user's context data generated on smart phone and designed a context generator. As a result, we can reduce a transmission data size and save a communication cost.

One of critical issues in the housing area is what strategies should be adopted for revitalizing contemporary communities in housing complex. It is expected that those strategies could encourage neighbourship and recover the existing community spaces. Based on the assumption that contemporary communities might have different characteristics from those of the traditional communities and spaces, this research aims to explore the possibility of new communities in a current context. With the development of the information communication technologies (ICT) and hardware systems, the environment would be capable of anticipating people's needs and then provide them with customization options to tailor the environment to their requirements. By incorporating the 'smart' paradigm, this paper introduces the concept of a smart community and space with the potential of mobile Augmented Reality(AR) as alternative strategies for activating the communities. The residents believe that existing common spaces need to be extendable and augmented by combining new technologies. The smart communities and spaces are expected to extend people's interaction to virtual world in aj real context, further combined with social network, it enables sustainable relationships among residents, contributina to a new type of community.

Objectives: This paper aims to identify the dimensions of community capacity in a public residence lease apartment complex in Seoul as a case study, and discusses their application to community health promotion. Methods: The research team performed a focus group interview and a brief survey with resident committee representatives to explore community context and to identify the dimensions of community capacity and their order of priority. Results: We identified many groups with different senses of community and various dynamics in the community. Seven dimensions of community capacity were identified. However, there are different developmental stages among them. Also there are some influences with the different directions in a dimension, e.g. leadership and citizen participation. Conclusions: This study illustrated the identification of the dimensions of community capacity focused on the perspective and recognition of the community and community member, as an effort to understand community capacity in domestic community health promotion context.

As the mobile environment becomes widely used, there is a growth on the concern about recognizing and sharing user context. Sharing context makes the interaction between human more plentiful as well as helps to keep a good social relationship. Recently, it has been applied to some messengers or mobile applications with sharing simple contexts, but it is still required to recognize and share more complex and diverse contexts. In this paper, we propose a context-aware messenger that collects various sensory information, recognizes representative user contexts such as emotion, stress, and activity by using dynamic Bayesian networks, and visualizes them. It includes a modular model that is effective to recognize various contexts and displays them in the form of icons. We have verified the proposed method with the scenario evaluation and usability test.

Context-awareness is a computing technology that automatically delivers useful services to users based on their situation. Most previous studies on context-awareness adopted the view that the user simply is a consumer of what the developer creates. Few studies addressed catering to the need of personalized services for the user. They are either too complex for the user to grasp or unable to express many useful services due to their weak expressive power. To address these issues, we propose Dobby as a new model and architecture for user-driven context-aware service development. Dobby enables the user to create services that are more suited to his personal preferences. We argue that Dobby offers an enhanced method for defining personalized context-aware services over existing methods.

This study aims to look into the characteristics of argumentation in the task context of 'Monty Hall problem' at a high school probability class. As a result of an analysis of classroom discourses on the argumentation between teachers and second-year students in one upper level class in high school using Toulmin's argument pattern, it was found that it would be important to create a task context and a safe classroom culture in which the students could ask questions and refute them in order to make it an argument-centered discourse community. In addition, through the argumentation of solving complex problems together, the students could be further engaged in the class, and the actual empirical context enriched the understanding of concepts. However, reasoning in argumentation was mostly not a statistical one, but a mathematical one centered around probability problem-solving. Through these results of the study, it was noted that the teachers should help the students actively participate in argumentation through the task context and question, and an understanding of a statistical reasoning of interpreting the context would be necessary in order to induce their thinking and reasoning about probability and statistics.

Here, we introduce various type of inorganic nanostructure synthesized with functional nanoparticles and silica. From two decades ago, functional inorganic nanoparticles have been synthesized and highlighted, now we moved to next level of wet-chemical synthesis. By integrating functional nanoparticles with silica, we were able to synthesize multi-functional nanostructure, which expand the applications of nanoparticles to catalyst, drug carrier, sensors. In this context, silica has been spotlighted due to its versatility. Silica has highly biocompatible, relatively transparent and stable under harsh conditions. Thus it can be used as good supporter to synthesize complex multi-functional nanostructure when mixed with other functional nanoparticles. A various shape of complex nanostructures have been synthesized including core-shell type, yolk-shell type and janus type etc. In this paper, we have described the purposes of synthesizing silica noncomplex and various case studies for biomedical applications and self-assembly.

Highly detailed geometric models are rapidly becoming commonplace in computer graphics and other applications. These complex models, which is often represented as complex1 triangle meshes, mainly suffer from the vast memory requirement for real-time manipulation of arbitrary geometric shapes without loss of data. Various techniques have been devised to challenge these problems in views of geometric processing, not a representation scheme. This paper proposes the new mesh structure for the compact representation and the efficient handling of the highly complex models. To verify the compactness and the efficiency, the memory requirement of our representation is first investigated and compared with other existing representations. And then we analyze the time complexity of our data structure by the most critical operation, that is, the enumeration of the so-called one-ring neighborhood of a vertex. Finally, we evaluate some elementary modeling functions such as mesh smoothing, simplification, and subdivision, which is to demonstrate the effectiveness and robustness of our mesh structure in the context of the geometric modeling and processing.

In order to successfully develop a large complex system, it is important that the systems engineering processes take into account the program context and characteristics. Among these processes, the requirements management process requires a management plan based on the program plans and systems engineering management plan (SEMP) to the connection with the program management system and the policy directives. In this paper, a systems engineering based requirement management scheme and guidelines for writing requirements are proposed. is proposed.
