The purpose of this paper is to investigate the phenomena of preposing and inversion in English from the discourse-pragmatic perspectives. We claim that different types of preposing can be unified to a single process of topicalization. We also show that diverse discourse functions of inversion can be subsumed under the ‘linking’ function with the prior discourse. It is followed a comparative discussion between preposing and inversion to find what similarities the two constructions share and what differences there exist between the two. It is concluded that the choice of a syntactic forms ultimately depends on the speaker's evaluation of the information status of the knowledge store of the hearer.

Block-based educational programming language(EPL) is commonly used due to its availability at low or no cost. It is also preferred tool of computing education due to its intuitive design, ease-of-use and its effectiveness in increasing algorithmic thinking abilities especially in elementary students. Physical computing is also necessary because it brings students closer to real-world problem solving by connecting the real world with the computing environment. However, due to high-cost and required knowledge in electrical engineering, many schools find the education difficult to access. The study shows significant increase in computational thinking abilities in both groups treated with EPL and additional physical computing education.

With the recent the use of spatio-temporal data mining which can extract various knowledge such as movement patterns of moving objects in history data of moving object gets increasing. However, the existing movement pattern extraction methods create lots of candidate movement patterns when the minimum support is low. Therefore, in this paper, we suggest the STMPE(Spatio-Temporal Movement Pattern Extraction) algorithm in order to efficiently extract movement patterns of moving objects from the large capacity of spatio-temporal data. The STMPE algorithm generalizes spatio-temporal and minimizes the use of memory. Because it produces and keeps short-term movement patterns, the frequency of database scan can be minimized. The STMPE algorithm shows more excellent performance than other movement pattern extraction algorithms with time information when the minimum support decreases, the number of moving objects increases, and the number of time division increases.

This study is aimed at putting forward effective methods of computer education for use in schools by comparing the schools of UK and Korea. It shows : 1) a big difference in infrastructure such as H/W and Network, 2) for S/W budget UK teachers have control over their own budget, but not in Korea, 3) government, school, teacher, student, and parent all have the same mind set to promote the use of information communication technology in the UK, but in Korea the government alone drives it with its own policy. At University level, potential computer teachers in the UK are emphasized to practice fields works in schools, but in Korea, the course mainly consists of education theory and pre-teachers get only four weeks field experience. In addition, computer teachers are often those with majors in different fields, but due to the lack of interest in computer education, they are forced into these empty positions. This often leads to conflict between students and teachers because of those teachers who do not have the necessary depth in knowledge of computers.

The purpose of this paper is to investigate high school students' reasoning characteristics in problem solving. To do this, we selected five high school students as participants and presented them some open problems which allow diverse solving approaches, and recorded their problem solving process. Through analyzing their problem solving process relate to their solution, we found the followings: First, students quickly try to calculate without understanding the given problem. Second, students concern whether their solution is right or not rather than consider mathematical warrants for the results of their strategies. Third, students have difficulties to consider more than two conditions at the same time necessary to solve problem. Forth, students are not familiar to use precedence knowledge relate to given tasks. Fifth, students could have difficulties in problem solving because of easy generalization.

In this article, we classify the middleschool students' mathematical modeling activities with three types as following: perceptive activity, cognitive activity, and metacognitive activity. And we research model development process through the interaction of perceptive, cognitive, and metacognitive activities. We report three results of our case study as following: First, students understanded the context of the modeling tasks on the base of their own experience and constructed the tasks with perceptive activity operating tool. Second, students developed various models with reorganizing cognitive activity which think and reason about perceptive activity-based model. Third, students were able to create generalizable and reusable models through metacognitive activities. This study revealed that the possible contribution of modeling activity as following. Students are able to understand abstractive mathematical knowledge as connecting between realistic activity and abstractive activity.

Fire monitoring system detects a fire based on the values of various sensors, such as smoke, CO, temperature, or change of temperature. It detects a fire by comparing sensed values with predefined threshold values for each sensor. However, to prevent a fire it is required to predict a situation which has a possibility of fire occurrence. In this work, we propose a fire recognition system using a fuzzy inference method. The rule base is constructed as a combination of fuzzy variables derived from various sensed values. In addition, in order to solve generalization and formalization problems of rule base construction from expert knowledge, we analyze features of fire patterns. The constructed rule base results in an improvement of the recognition accuracy. A fire possibility is predicted as one of 3 levels(normal, caution, danger). The training data of each level is converted to fuzzy rules by FCM(fuzzy C-means clustering) and those rules are used in the inference engine. The performance of the proposed approach is evaluated by using forest fire data from the UCI repository.

LBS(Location Based Services) provide the location-based information to its mobile users. The primary functionality of these services is to provide useful information to its users at a minimum cost of resources. The functionality can be implemented through data mining techniques. However, conventional data mining researches have not been considered spatial and temporal aspects of data simultaneously. Therefore, these techniques are inappropriate to apply on the objects of LBS, which change spatial attributes over time. In this paper, we propose a new data mining technique for identifying the temporal patterns from the series of the locations of moving objects that have both temporal and spatial dimension. We use a spatial operation of contains to generalize the location of moving point and apply time constraints between the locations of a moving object to make a valid moving sequence. Finally, the spatio-temporal technique proposed in this paper is very practical approach in not only providing more useful knowledge to LBS, but also improving the quality of the services.
