Scientific literacy has long been as one of the key goals of science education, and using scientific inquiry in school science has became an important objective to be achieved. The processes of scientific inquiry consist of proposing/developing inquiry question, designing and conducting investigation, collecting, analyzing and interpreting data, and communicating the results. However, most students experience mainly collecting and transforming data in inquiry processes in science class and they are barely exposed to the opportunities of proposing/developing inquiry questions. Middle school earth science preservice teachers participated in this study (N=36) and their abilities of developing inquiry questions were surveyed. Participants' abilities of developing inquiry questions were investigated whether they were enhanced with activities using the Inquiry Questions Development Guide (IQDG). Also, this study was interested in whether there was any relationship between abilities of developing inquiry questions and designing inquiry investigation. The results of this study were as follows; first, the level and preciseness of inquiry questions and its preciseness developed by participating teachers were enhanced after experiencing IQDG. In addition, teachers' dominating inquiry question-types were two: one is a 'relationship-inquiry question' in which students could discover the relationship between results found in the given experimental situations and the other one is a 'why-how inquiry problem' in which students could explore a cause or a process that results in the outcomes. Finally, the higher level of and preciseness the of inquiry questions were identified as an important factor the determined teachers' abilities of designing more logical investigation. A process of proposing/developing inquiry question was identified as one of the most important processes contributing to a success of scientific inquiry investigation.

Recently, new teaching methods for communicating with teachers and students have been emerged according to the trends of decreasing the school-age population and the development of the mass media. We have applied teaching-learning model based on the flip learning to the college students in this work. As a result of the test for the customized flipped learning teaching-learning model in pre-class, the attendance rate of the major subject was 92.3% whereas that in liberal arts courses other than majors revealed 87.6%. This result for attendance rate shows that first year students in the radiology department have been actively participated in pre-class of the major subject than that of the liberal arts curriculum. From comparing the differences between the study group that was applied flipped learning in class and the non-applied group, the research group showed higher scores in knowledge, skills, and attitudes than the comparative group. In addition, more than 90% of the learners improved their responsibility, problem solving ability, creative thinking, cooperative ability, and communication ability through this learning program. From the test for the difference in the role of radiologists in the post class, the mean score was 4.40 for the group applied the teaching-learning model while that for non-applied group was 2.10. Hence, from such results, we see that this teaching-learning model is appropriate and needs to be extended to cultivate basic skills in radiology and relevant vocational education.

Citizen participation and Living Lab are attracting interest as one of the major strategies for the success of smart cities. In a Living Lab, citizens, who are the end-users of technology, participate in the search for alternatives to define and solve problems and repeat experiments to verify alternatives in a circular process. The purpose of this research was to present an operating model of a citizen-participating online community platform to improve urban problems, implement and test it, and show its applicability. To this end, an operation model of a citizen-participating online community platform was proposed to improve urban problems. An online platform was designed and implemented to reflect the functions pursued by the operation model. Finally, a pilot test for the function was performed using the Oma Elementary School case located in Ilsan, Goyang-si, Gyeonggi-do. The operating model was designed with the city's pedestrian environment and children. As a result, the sharing and communicating process of urban issues among community members worked appropriately according to the designed intention. The Living Lab coordinator could visualize and view urban issues posted by users on a map based on location information. Visualizing the urban problem as a heat map confirmed that urban problems were concentrated in a specific area.

Purpose: The aim of this study was to determine the kinematical characteristics of the pendular and the translational movements of each cervical vertebra at flexion and extension for understanding the mechanism of injury to the cervical spine. Methods: Twenty volunteers, young men (24~37 years), with clinically and radiographically normal cervical spines were studied. We induced two directional passive movements and then took X-ray pictures. The range of pendular movement could be measured by measuring the variation of the distance between the center point of two contiguous cervical vertebrae, and the range of translational movement could be measured by measuring the variation of the shortest distance between the center point of a vertebra and an imaginary line connecting the center points of two lower contiguous cervical vertebrae. The measurements were done by using a picture archiving and communicating system (PACS). Results: The total length of all cervical vertebrae in the neutral position was, on average, 133.66 mm, but in both flexion and extension, the lengths were widened to 134.83 mm and 134.79 mm, respectively. The directions of both the pendular and the translational movements changed at the $2^{nd}$ cervical vertebra, and the ranges of both movements were significantly larger from the $5^{th}$ cervical vertebra to the $7^{th}$ cervical vertebra for flexion and combined flexion and extension motion (p<0.05). Conclusion: The kinematical characteristics for flexion and extension motions were variable at each level of cervical vertebrae. The $1^{st}$ and the $2^{nd}$ cervical vertebrae and from the $5^{th}$ to the $7^{th}$ cervical vertebrae were the main areas of cervical spinal injury. This shows, according to "Hook's law," that the tissues supporting this area could be weak, and that this area is sensitive to injury.

What Michel Foucault has interpreted about Jeremy Bentham' Panopticon in the point of power relationship of ones's gaze is put in comparison with the characteristics shown in the modern media and mutual meanings are interpreted in the respect of a power relationship of modern gaze. Modern people communicating through media are placed in certain type of power relationship. This study analyzed the difference of it in the respect of the power of gaze in Panopticon and the consumption of information. Panopticon assumes single-network supervision, that is, one-way gaze. However, in modern media, interactive communication is possible based upon the development of information telecommunication technology. Therefore, this study aims to compare and study modern single-network supervision and multi-networks supervision based on information telecommunication technology. The development of various media such as internet, mobile phone and smart card has changed the single-network supervision system structured since modern times into the multi-network supervision system. 'Gaze-power' presented in the relationship to media enables us to discuss the problem of mutual receptiveness, the presence of various powers according to information structure and consumption power. In particular, the form provided by modern media has the complexity of mutual communication in the relationship of multi-networks, rather not assuming only one-way nature of single-network. Therefore, the approach of communication issue provided by modern media in the respect of multi-networks relationship was done by the power relationship of gaze in the respect of information communication. Gaze determines the power of watching. In addition, the visualization format aims at the power.

Informal engineering education program for high school students was developed to cultivate engineering literacy using the human resources and facilities of university. Plant factory, a smart farming technology, was selected as a main theme, and the novel engineering camp program involving engineering design activities and intra-linter-team works was planned. The camp program was applied to 38 high school students in an active learning classroom. Five teams were constructed according to elemental technologies such as biotechnology, information-communication technology, energy engineering, mechanical engineering and architectural engineering, and the students were participated in intra- and inter-team activities to achieve the final goal of 'the construction of a plant factory in school'. The team works were conducted according to the eight steps of engineering design process (identifying the problem and need, identifying criteria and constraints, brainstorming possible solutions, selecting the best possible solution, constructing a prototype, testing and evaluating the solution, communicating the solution, and refining design). Participants' satisfaction survey showed that the satisfaction on the contents of engineering design was 4.48 on 5-point Likert scale. The participants' satisfaction on creative activity and systematic methodology was 4.43 on 5-point Likert scale. 97% of participants responded positively to team works, and 92% of participants were satisfied with career mentoring activity supplied by undergraduate/graduate students. These results indicates that the engineering camp program involving engineering design activity and intra-/inter-team works can contribute to cultivate engineering literacy such as creativity, problem solving ability, collaboration, communication skills for high school students, and to increase their interests in engineering fields.

The US Federal Reserve (Fed) has decided to cut interest rates. When we look at the expression of the FOMC statements at the time of policy change period we can understand that Fed has been communicating with markets through a change of word selection. However, there is a criticism that the method of analyzing the expression of the decision sentence through the context can be subjective and limited in qualitative analysis. In this paper, we evaluate the signaling effect of FOMC statements based on previous research. We analyze decision making characteristics from the viewpoint of text mining and try to predict future policy trend changes by capturing changes in expressions between statements. For this purpose, a decision tree and neural network models are used. As a result of the analysis, it can be judged that the discrepancy indicators between statements could be used to predict the policy change in the future and that the US Federal Reserve has systematically implemented policy signaling through the policy statements.

Our study is focused on a multiple-agent system to provide efficient collaborative work by automating the conference calling process with the help of intelligent agents. Automating the meeting scheduling requires a careful consideration of the individual official schedule as well as the privacy and personal preferences. Therefore, the automation of conference calling needs the distributed processing task where a separate calendar management process is associated for increasing the reliability and inherent parallelism. This paper describes in detail the design and implementation issues of a multiple-agent system for conference calling that allows the convener and participants to minimize their efforts in creating a meeting. Our system is based on the client-sewer model. In the sewer side, a scheduling agent, a negotiating agent, a personal information managing agent, a group information managing agent, a session managing agent, and a coordinating agent are operating. In the client side, an interface agent, a media agent, and a collaborating agent are operating. Agents use a standardized knowledge manipulation language to communicate amongst themselves. Communicating through a standardized knowledge manipulation language allows the system to overcome heterogeneity which is one of the most important problems in communication among agents for distributed collaborative computing. The agents of our system propose the dates on which as many participants as possible are available to attend the conference using the forward chaining algorithm and the back propagation network algorithm.
