  • Knowledge of the physical locations of access point of WLAN is becoming increasingly important with the rise of location-based services. In this article, we propose a new AP localization method using neural network approach. Basic theory and properties are derived for precise outdoor AP localization using GPS location information and RSSI. Rules for neural network model are derived and simulation has finally been done to demonstrate the efficiency of the proposed method. The simulation results show that the proposed method can result in AP localization with very. low error probability.

  • In this study, the multiplicity of synchronous online class discussion activity is explored at conceptual level. From the cultural-historical activity theory (CHAT), each utterance may be considered as a product of the activity system. Alderfer's ERG theory is employed as another theoretical framework for the study. Based on the subject's existence, relationship, growth needs, their class discussion activities constitute four different dimensions: physical/biological, cultural/institutional, social/relational, and cooperative knowledge construction. It is inherent in individual activities and has a different arrangement according to their interests and situations, and at the same time acts as a factor of cooperation and competition among the participants. Through this, collective discussion activities represent complex and dynamic development patterns.

  • This study attempts to figure out the impact of Information and communication technologies (ICTs) on spatial structure and to speculate on spatial strategies in the electronic economy from a geographical perspective. The unprecedented development of ICTs based on the explosive use of the Internet was enough to lead to the expectation that physical distance would not be a significant barrier in business activities. In fact, however, at least at a current stage, the development of ICTs has not automatically removed the inequality in spatial structure. The accessibility to electronic space is different by economic and social status within a country as well as between countries. The importance of place, locality, and place-specific assets has been strengthened in the global economy. Physical proximity is still of great importance because it helps to minimize transaction costs, to exploit place-specific social networks, and to accumulate credibility for successful businesses. Likewise, the development of electronic commerce such as B2B and B2C EC also does not necessarily result in the ignorance of place and locality. Rather, the recognition of the importance of spatial strategies is extremely important for the success in online businesses. As a conclusion, the spatial dimension becomes more important in the digital era for successful businesses and balanced regional developments than ever before. The need for the improvement of ICT infrastructures, the development of human resources, and the establishment of regional innovation systems in peripheral areas cannot be overemphasized even in the digital era.

  • In this paper, the activities for scientifically-gifted high school students in the 2006 International Young Physicists' Tournament were analyzed, from the perspective of the social aspects of creativity. To understand this, the process by which the activities were similar to the system model of creativity developed by Csikszen-tmihalyi were analyzed. Our aim was to elicit the educational implications of cooperative science problem solving skills and to discuss the results from their social perspective. It was found that participants interacted consistently with peers, teachers, and the culture that was developed during the course of the tournament. This was found to be very similar to the way in which novel knowledge in the system model of creativity is produced. In the tournament, the juries' assessment was based on students' presentations, discussions, and reviews. This was also very similar to how novel knowledge in the model is selected. Solving problems cooperatively and evaluating the results through group discussion are well reflected the social aspects of creativity. Due to the fact that such tournaments for scientifically-gifted elementary students are rapidly increasing in popularity, such activities will increasingly become more important. It is necessary, therefore, to study the social aspects of creativity for the gifted in elementary and middle school.

  • The purpose of this study is to develop the main subjects of the job-based curriculum by deriving the job analysis results of general security job workers in the physical protection field responsible for responding to threats to nuclear materials and nuclear facilities. In the job analysis stage, FGI was conducted on 7 content experts to derive 8 duties and 55 tasks. In addition, knowledge and skills were drawn for each task. In the analysis of educational needs, surveys were conducted for workers in general security jobs to derive the top 25 educational priorities through t-test and Borich needs assess model. At the stage of selecting core tasks and organizing required/optional contents, 42 tasks, both above average or at least one of them, were derived as core tasks based on the result of evaluation of importance and difficulty ratings of 55 tasks through a questionaire. In addition, tasks applied to the top 25 rankings derived from Borich needs assess model were applied as the required contents when designing courses, and tasks which applied only one of them were selected as optional contents. At the stage of required/optional modules and educational contents, four required modules and five optional modules were derived by drifting similar tasks between the required and optional contents. Based on the above results, the study suggested academic and practical implications and future suggestions.

  • The purpose of this study is to explore the philosophical position of various scientific theories based on the scientific worldviews for science education. In addition, it aims to expand science education, which has usually dealt with epistemology and methodology, to ontology, that is, to the problem of metaphysics. It can be said that there exists a physical realism, traditionally defined as a strong determinism of the metaphysical belief. That is fixed and unchanging objective scientific knowledge independent of our minds, which was established by Newton, Einstein and Schridinger. What can be seen in the natural laws of dynamics can be called 'mathematicization'. Einstein also shook the traditional views to some extent through the theory of relativity, but his theory was still close to traditional thinking. On the contrary, to escape from this rigid determinism, we need anthropomorphic concepts such as 'possibility' and 'chance'. It is a characteristic of the modern scientific worldviews that leads the change of scientific theory from a classically strong deterministic thought to a weak deterministic accidental accident, probability theory, and a naturalistic point of view. This can be said to correspond to Darwin's theory of evolution and quantum mechanics. We can have three types of epistemological worlds that justify this ontological worldviews. These are rationalism, empiricism and naturalism. In many cases, science education does not tell us what kind of metaphysical beliefs the scientific theories we deal with in the field of education are based on. Also, science education focuses only on the understanding of scientific knowledge. However, it can be said that true knowledge can bring understanding only when it is connected to the knowledge of learned knowledge and the learner's own metaphysical belief in the world. Therefore, in the future, science education needs to connect various scientific theories based on scientific worldviews and philosophical position and present them to students.

  • Books in libraries can be highly refined information. Google invests digitization of books in libraries. But the digitization of books that has a variety of interests, coupled with several problems, including class action, in addition the many critical discussions are underway. Korea pushed the national digitization projects, what are libraries' digitizing their collection of many books. Of course, in publishing and digitization of the target is limited to books published ahead of Google. However, the Library Act was amended for the reposition of online materials, but only in the ways that Google's case is different. Library Act permits collection of online resources through the library to allow, the legislation can be considered as leading act. However, online data is publicly not available through the Internet, so this service hae limited means and range unlike Google. This paper, the digitization of books in the library due to copyright, examines the legal issues looking for the desirable solution. Physical library's main role had been kept the book, but we use the book in terms of policies needed to consider. To overcome these limitations of Copyright Act, this paper researches the relation of Google Book Search in our Copyright Act, and considers introduction as the fair use doctrine and the digital repository system.

  • This study analyzed all of the research articles published in six of the Korean science education journals in the past three decades. The purpose of this research synthesis was to identify gender differences in hundreds of research articles accomplished at the personal, local, and national level that have repeatedly been reported in several international comparative studies. There were few of articles that focused on gender issues, but 279 articles presented a result of gender issues separately. Of the 279 articles, we finally analyzed 225 research articles for a statistical significance. The articles were divided into two types of research method: test-based studies and experiment-based studies. The results of research synthesis in test-based studies were as follows: The largest number of studies reported male superiority in science knowledge and science-related attitude, which is similar to the results of recent international studies. In particular, gender differences were the biggest in science-related attitudes and the least in scientific process skills. The result of research synthesis in experimental studies was that the largest number of articles did not show significant gender differences in the effect of the applied program. It is noteworthy that the applied science education programs tend to be more effective in improving female students' scientific attitude and male students' science knowledge. It is necessary to develop more gender-inclusive science programs for female students to feel science more positively.
