  • In a variety of network environments, the provision of context-aware services, it is difficult to integrate and share because of the heterogeneity problem between distributed data. This paper proposes the integration model using the ontology as a method for solving the above. This uses an ontology to integrate the context-aware informations that are collected. The ontology is generated by the acquisition, semantic analysis and inference of the metadata of the context-aware information. This is the basis of the analysis and analysis of the additional system. Accordingly, this paper studies ways to create an ontology and apply them. The advantage of the proposed scheme can be used without modifying the existing tools, it is possible to easily perform the expansion and consolidation of the system.

  • As the amount of information is rapidly growing, and the ubiquitous urban environments are emerging, the question which information type to provide and which communication media to support is a major challenge for commercial and public travel-information service providers. The current research reports the first findings of analyses of recent data, collected in metropolitan Seoul, about the acquisition of travel information and the communication media used. The study is based on the assumption that information acquisition and choice of communication medium is strongly context-driven. The study applies CHAID analysis to find homogeneous segments in information acquisition and use of communication media. Findings indicate that transport mode and activity are important determinant of information acquisition and choice of media. The type of travel information acquired co-varies strongly with transport mode and activity. In addition, we found evidence of time of day effects. Similarly, the choice of communication medium depends on the type of travel information searched for, transport mode and activity. The results suggest important implications of managerial and policy measures, in particular the dynamic, contextual market segmentation.

  • This study investigated the factors influencing the knowledge acquisition of Thai local partners from advanced foreign partners through international joint ventures(IJVs). For this purpose, this study initially identified three dimensions of characteristics in the context of IJVs that would influence local partners' knowledge acquisition - a local partners' own characteristic (absorptive capacity), a relationship characteristic with IJVs (proximity to the equal equity ownership), and a relationship characteristic with foreign partners (trust), and examined their effects on local partners' knowledge acquisition. The study further investigated the moderating effects of the tacitness of knowledge on the relationships between those characteristics and knowledge acquisition. Based on the data collected from Thai IJV local partners, results revealed that a local partners' own characteristic, absorptive capacity, and a relationship characteristic with IJVs, proximity to the equal equity ownership, had a strong positive effect on local partners' knowledge acquisition. Results further showed that the tacitness of knowledge strengthened the relationships between absorptive capacity and knowledge acquisition and between trust and knowledge acquisition, but not the relationship between proximity to the equal equity ownership and knowledge acquisition.

  • In order to provide healthcare services based on context-awareness techniques in IoT environments, a system requires to collect user profile and environmental information. To collect environmental information, accessing sensor device and gathering sensor data should be proceeded. Although this process is necessary to build environmental information, there is no proper sensor data acquisition model. In this paper, we propose sensor data acquisition model that contains schema to connect each device and to collect various kinds of data from sensor device at one point. In experiment, we demonstrate sensor data acquisition procedures with a description following suggested scheme.

  • The managerial effort to acquire and maintain detailed construction control data has been the major barrier to improving the effectiveness of construction project management. Therefore, utilizing data acquisition technologies (DAT) can greatly improve the construction management processes by automating the data collection. Even though many researches attempted to explore the DAT utilization in construction, there has been no comprehensive study that examine the viability of DAT usage from a comprehensive perspective. In this context, the purpose of this study is to investigate the current efforts and future recommendation of DAT implementation in the construction industry.

  • This paper is a discussion on the archival appraisal system that operates to document big events of the society or major public policies. The writer brought up three suggestions; the first is to develop documentation strategy to select archives at the same time it is created. This means that what matters is the scenes contained in the archives, and therefore they must reflect as wide social context as possible, which the writer considered as being caused by the change of thinking on the value of archives. The second is to develop tools to acquire archives that satisfy such strategy. The third is the sustainability of such documentation strategy and archival acquisition methods. Regarding this point, the writer discussed the problems of current national archival system of Korea.

  • The progress is widely used as a critical index for successful construction project management. In spite of the importance of progress measurement, the excessive management effort to collect and maintain detailed data has been highlighted as a major barrier to measurement of highly accurate progress. In order to reduce the required workload and to enhance accuracy, several researches have been conducted. These researches can be categorized into two groups. First group focuses on automated data collection utilizing advanced technologies only for limited construction tasks. The second group is a research area where the standard progress measurement methodologies encompassing entire construction tasks are investigated. Topics include the adjusting the level of details, standardizing work processes, and applying flexible WBS. However, the techniques for automated data collection are not fully investigated yet in the second group. Combining these two research areas can provide a solution for more effective progress management in terms of enhancing accuracy and optimizing workload. However, there has been no comprehensive research addressing these two research groups in an integrated manner. In this context, the purpose of this paper is to propose a methodology that identifies the most suitable measurement method and data acquisition technology (e.g., GPS, RFID, etc.) for entire construction tasks of a project. The proposed methodology in this paper will be able to facilitate the selection process of data acquisition technologies for entire construction tasks of a project and to support the overall enhancement of automated progress management.

  • The present study, focusing on the stress-shift constructions, examines the tendency of young children to give wrong wide scope interpretation in language acquisition and questions the validity of the guess pattern hypothesis argued by Grodzinsky & Reinhart (1993). According to the hypothesis, children know that they have to construct a reference-set, keep two representations in working memory, and check whether the interpretation needed in the given context justifies selection of competing reference sets, but their working memory is not big enough to hold the materials needed to complete the execution of this task. Hence they give up and resort to a guess. 1 carried out an experiment of 16 Korean children aged 3;9 to 6;2 to find out whether children have more difficulty in the interpretation of stress-shift constructions than of constructions with a nuclear stress, and therefore perform the interpretation of the former by guessing. Assuming that the tendency is caused by a deficiency in contextual computation rather than reference set computation, I try to explain it in terms of pragmatic considerations.

  • Learner-centered approach has been a recent research focus in the second language acquisition, but few studies have dealt with how to develop learner autonomy, particularly in a computer-assisted language learning environment. The paper first illustrates the importance of promoting learner autonomy in the EFL context and elaborates the three main factors contributing to its development. Then it focuses on how the CALL research project promotes autonomous learning through a small-scale study in Gyeongju University. Both quantitative and qualitative methods have been employed to examine whether in the CALL project learners exercise control over their own learning and evaluate the outcome. The results indicate that due to a flexible syllabus, highly motivating research topics and the network-assisted environment, learners do take responsibility for most aspects of learning and thus the CALL project proves to be a promising approach for autonomous learning.
