  • An Internet of Things(IoT) technology which provides intelligent services by combining context-awareness based intelligences, inter-communication is made of between things and things or between things and person through the network connected with intelligent things is spreading rapidly. Especially as this technology is converged into smart device, mobile, cloud, big data technologies, it is applied into various domains. Therefore, this is different from existing Web or Mobile Application. New types of IoT applications are emerging by adapting IoT into Web or mobile. Because IoT application is not only focused on software but also considering hardware or things aspect, there are limitations existing development process. Existing development processes don't consider analysis and design techniques considering both hardware and things. We propose not only a meta-model for development process which can support IoT application's development but also meta-models for main activities in this paper. Especially we define modeling elements by using UML's extension mechanisms, provide development process, and suggest design techniques how to apply those elements into IoT application's modeling phase. Because there are many types of IoT application's type, we propose an Android and Arduino-based on IoT application as a case study. We expect that proposed technique can be applied into many of various IoT application development and design with a form of flexible and extensible as well as main functionalities or elements are more concretely described. As a result, it brings IoT application's flexibility and the effect of quality improvement.

  • The purpose of this study was to investigate the effects of Read Along by Google with primary English learners' pronunciation and affective domains. In order to answer these two questions, a 4-week pilot study was conducted with 24 participants in the 6 th grade. Read Along as a main learning tool was utilized for a reading-aloud activity, and a pre-/post pronunciation test and survey on the affective factors were distributed as a research instrument. The results indicated that a read-aloud activity with Read Along brought a positive impact on the development of learners' pronunciation ability in terms of accuracy and fluency. Participants showed improvement in the post-pronunciation test, compared to the pre-one and there was a significant difference based on the result of the paired samples t-test. Next, the results of the survey on the affective domains illustrated that participants showed overall improvement in learning interest and confidence and there was a significant difference in these factors. Yet, there was not a significant difference in the learning attitude, even though they showed partial improvement.

  • Semantically similar XML documents in the same application domain might often conform to different schemas. To uniformly view and query such XML documents, we need an efficient method of integrating XML schemas. This paper proposes a sophisticated method for integrating XML schemas in the same application domain. To compute mapping relationships between schemas, the proposed method utilizes various relationships, such as synonyms and hypernyms, between lexical items based on dictionaries and domain ontologies. Particularly, the relationships between lexical items are elaborated by taking their structural information into account. In addition, this paper proposes a more accurate method for integrating compositors. Experimental results with schemas in various application domains show that the utilization of domain ontologies and the structural relationships between lexical items enhance the precision and recall of integrated schemas.

  • In times of the civil uses of commercialized high-resolution satellite imagery, applications of remote sensing have been widely extended to the new fields or the problem solving beyond traditional application domains. Transportation application of this sensor data, related to the automatic or semiautomatic road extraction, is regarded as one of the important issues in uses of remote sensing imagery. Related to these trends, this study focuses on automatic road extraction using Gradient Direction Profile Algorithm (GDPA) scheme, with IKONOS panchromatic imagery having 1 meter resolution. For this, the GDPA scheme and its main modules were reviewed with processing steps and implemented as a prototype software. Using the extracted bi-level image and ground truth coming from actual GIS layer, overall accuracy evaluation and ranking error-assessment were performed. As the processed results, road information can be automatically extracted; by the way, it is pointed out that some user-defined variables should be carefully determined in using high-resolution satellite imagery in the dense or low contrast areas. While, the GDPA method needs additional processing, because direct results using this method do not produce high overall accuracy or ranking value. The main advantage of the GDPA scheme on road features extraction can be noted as its performance and further applicability. This experiment study can be extended into practical application fields related to remote sensing.
