Effective energy consumption now becomes one of the area of knowledge management which potentially gives global impact. It is considerable for the energy management to optimize the usage of energy, rather than decreasing energy consumption at any cases. To resolve these challenges, an intelligent and personalized system which helps the individuals control their own behaviors in an optimal and timely manner is needed. So far, however, since the legacy energy management systems are nation-wide or organizational, individual-level energy management is nearly impossible. Moreover, most estimating methods of energy consumption are based on forecasting techniques which tend to risky or analysis models which may not be provided in a timely manner. Hence, the purpose of this paper is to propose a novel individual-level energy management system which aims to realize timely and personalized energy management based on context-aware computing approach. To do so, an index model for energy consumption is proposed with a corresponding service framework.

Treatment and management of chronic low back pain (CLBP) should be tailored to the patient's individual context. However, there are limited resources available in which to find and manage the causes and mechanisms for each patient. In this study, we designed and developed a personalized context awareness system that uses machine learning techniques to understand the relationship between a patient's lower back pain and the surrounding environment. A pilot study was conducted to verify the context awareness model. The performance of the lower back pain prediction model was successful enough to be practically usable. It was possible to use the information from the model to understand how the variables influence the occurrence of lower back pain.

Owl-based ontology is useful to realize the context-aware services which are composed of the distributed and self-configuring modules. Many ontology-based inference engines are developed to infer useful information from ontology. Since these engines show the uniqueness in terms of speed and information richness, it's difficult to ensure stable operation in providing dynamic context-aware services, especially when they should deal with the complex and big-size ontology. To provide a best inference service, the purpose of this paper is to propose a novel methodology of context-aware engine selection in a contextually prompt manner Case-based reasoning is applied to identify the causality between context and inference engined to be selected. Finally, a series of experiments is performed with a novel evaluation methodology to what extent the methodology works better than competitive methods on an actual context-aware service.

The ERP system comes to existence in the period of change. In other words, the ERP system is adopted to the company with BPR project. In general, the ERP system is introduced to companies as packages rather than in-housing systems. There are several researches in IS literatures which have a conclusion that organizational context affects the performance of ERP system. This study attempts to review the organizational context from the prospective of organizational structure and change management. Regarding the organizational structure, we choose some widely known variables such as the degree of formalization and centralization. For the analysis of change management, we set the variables, which are the most importantly considered, such as the power of CEO's promotion and user participation. The extent of customizing is introduced as moderating variables between the organizational context and the implementation performance. With collected data, we performed the reliability test, the factor analysis and the regression analysis. In summary, the introduction of an information system such as ERP system has a behavioral and organizational impact. The organizational change may breed resistance and opposition and can lead to the failure of the system. Therefore, implementation of the system requires careful change management, active involvement of users and high level of management support.

Recently, the area of ubiquitous computing has gained a great attention both in academics and in industry. However, previous research on this area attempts the categorization in part of context and the critical success factors (CSFs) and services of ubiquitous computing unsuccessfully. The purpose of this paper is to propose a framework on ubiquitous computing, including its context, roadmap, CSFs, and services.

Although construction site photos contain important as_built information, technique and knowledge, there has been lack of frameworks to store and manage construction site photos efficiently and effectively. The problems in site photo management are getting increasingly serious, as digital cameras are adapted as collection tools of site Photos. This research suggests an information framework(named CIIM: Construction Image Information Model) to manage and share construction information based on 5W1H in order to derive construction context, which includes technologies, lessons-teamed and knowledge, from construction site photos, and a site photo management system named CIMS II (Construction Image information Management system II was developed to verify the model. It is expected that the results of this research that are an information framework and an system could help more effective classification, management, search and derivation of context in a construction project.

There have been many requests for development of senior housing in Korea. Therefore it was very important to review how senior houses are established and managed in other countries. In this point, this research compared the actual conditions of the homes for the elderly in the U.K, U.S.A and Japan. Through the process, this research aimed to find the implications for Korea. The research was conducted by the literature review on senior congregate housing with Franklin's(1998) social constructionism perspective. This kind of research might be utilized as a theoretical framework for performance of any systems of housing for the aged. In this study, the researchers suggested the implications of senior congregate housing as follows. Firstly, in terms of structural context, government in the U.K, U.S.A., and Japan were positively concerned with solving the housing problems for senior citizens despite some differences. Secondly, from an institutional context, institutions related with provision, construction, and management of senior congregate housing were systematically consolidated and they all adapted the housing and welfare policy. Thirdly, in organizational context, there was an organization in charge of provision and management that exclusively oversaw the housing for the elderly in both the public and private sectors. Fourthly, in operational context, standards regarding space were clearly set both for individual units and common spaces as well as for facilities and services for the residents. Finally in terms of intersubjective context, the competency of housing manager and ways to involve the families which were important for residents' independent life were under study.

Spatial data streams from sensors are useful in context-awareness for many types of applications. However, an important gap is found between spatial data stream management in real-time and complex computation for spatial context-awareness, and this brings about serious difficulty to integrate spatial data stream processing and context-awareness. In this paper, we present a system called SCONSTREAM(Spatial CONtext STREAm Management) that we have developed to resolve the gap between spatial data stream and context-awareness. The key approach of our system is to filter off unnecessary spatial data streams and convert them to the spatial context streams, which are smaller and more suitable to be processed by the context-awareness module than raw data from sensors. By experimentation, We show that SCONSTREAM resolves the functional gap between spatial stream processing and spatial context-awareness module.

The article proves the relevance of developing conceptual frameworks for managing the quality assurance of logistics activities in the context of socio-economic interaction of their participants. It is established that the fundamental difference of the logistic approach in management from traditional approaches is the allocation of a single management function of previously separated, disparate material flows, as well as economic, technological, information integration of chain links into a single system capable of effective management of these flows. It is substantiated that the functioning of the enterprise as a logistics system can be represented in the form of a triad of logistics components, namely: supply logistics, production logistics, sales logistics. Management of quality assurance processes of logistics activities in the context of socio-economic interaction of their participants is a functional component of the entire logistics system due to the quality of work and interaction of all participants in the implementation of certain activities. The quality of logistics activities will affect the level of economic potential, rationalization and optimization of all logistics flows. It is proved that the management of quality assurance processes of logistics activities in the context of socio-economic interaction of their participants involves the following main areas: the introduction of a quality system of logistics processes; development and implementation of the general strategy of quality improvement at the enterprise; internal integration; controlling. Management of quality assurance processes of logistics activities in the context of socio-economic interaction of its participants requires compliance with the following requirements: systematic and comprehensive management of all flow processes; coordination of criteria and indicators for assessing the effectiveness of the entire logistics system; dissemination of the use and application of information technology; ensuring partnerships and close interaction of all participants in sales networks.
