Educational Programming Language has been reported to expand thinking ability and to give help in creative problem solving ability by numerous researches. Researchers are verifying the educational effects of EPL by applying it to various area, but researches in effective application of EPL is yet incomplete. Thus, for effective application of EPL, this research has verified the project completing ability depending on studying style targeted to college senior students. As results of verification, first, the results showed significant differences in project completing abilities depending on information processing methods, and learners who preferred self-reflecting introspection showed high scores. Second, in learning style the divergers showed the highest scores. This research suggested the necessity of guidance and detailed planning of self-reflecting introspective activity in ideas that would be realized by learners through searching for factors that could enhance the degree of project completion in programming learning using EPL.

With the change of global awareness of Computing education and introspection about Computer education focused on ICT literacy, efforts are being made to reflect computational thinking in the new curriculum. But if computational thinking would be possible at school, it require tremendous cost to prepare computers for school. In this study, we investigate potentiality and constraints of the one board computer to teach computational thinking in school. We study fundamental performance, application of physical computing and programming education, maintenance of the computers, power consumption of the one board computers which is raspberry pi, beagle bone black, and pcduino3. The result of the study show that one board computer can substitute desktop of the school unless tasks related to require massive data storage and processing. We draw a conclusion that Pcduino3 is well-suited for computational thinking education.

The purpose of this study was to verify the effects of psychodrama group counselling, and to determine its applicability as a nursing intervention for the promotion of mental health of clients in their developmental stages. Methodological triangulation was used for research design. For quantitative study, quasi experimental study design with nonequivalent control group was used to test the effects of psychodrama group counselling. For each experimental and control group convenient samples of 15 nursing students were selected, and observed from May to Nov. 2000. For experimental group, the treatment was given for 2 hours each week, totaling 20 hours. The questionnaire consisted of 24 items of physical symptoms from CMI. 40 items of Spielberger Anxiety Scale, and 21 items of Beck Depression Scale. Reflective journal was written by the experimental group. The data were analyzed using chi-square and Mann-Whitney U test. For the qualitative study, the contents of the reflective journal were analyzed into categories and classifications. The results of the study were as follows; 1. There was a significant difference on physical health status between the experimental and the control group 2. There was a significant difference between two groups on the mean scores of mental health before and after psychodrama group counselling. 3. The qualitative analysis of reflective journal resulted in 4 categories and 13 classifications, which was reflected by the experience of the psychodrama group counselling. The four categories were self introspection, psychological support, improvement of interpersonal relationship and self development. The thirteen classifications are self-discovery, discovering others, emotional catharsis, positive thinking, formation of consensus, comforting, being free, being comfortable, understanding, maturing personal relationship, acquiring self-confidence, new challenges, and planning for the future. Based on the study findings, the psychodrama group counselling had promoted not only physical but also mental health of nursing students.

In sensor network processing environments, current location tracking methods have problems in accuracy on receiving the transmitted data and pinpointing the exact locations depending on the applied methods, and also have limitations on decision making and monitoring the situations because of the lack of considering context-awareness. In order to overcome such limitations, we proposed a method which utilized context-awareness in a data processing module which tracks a location of the magnetic object(Magnetic Line Tracer) and controlled introspection data based on magnetic sensor. Also, in order to prove its effectiveness we have built a wireless sensor network test-bed and conducted various location tracking experiments of line tracer using the data and resulted in processing of context-aware data. Using the new data, we have analyzed the effectiveness of the proposed method for locating the information database entries and for controlling the route of line tracer depending on context-awareness.

Antivirus is an important issue to the security of virtual machine (VM). According to where the antivirus system resides, the existing approaches can be categorized into three classes: internal approach, external approach and hybrid approach. However, for the internal approach, it is susceptible to attacks and may cause antivirus storm and rollback vulnerability problems. On the other hand, for the external approach, the antivirus systems built upon virtual machine introspection (VMI) technology cannot find and prohibit viruses promptly. Although the hybrid approach performs virus scanning out of the virtual machine, it is still vulnerable to attacks since it completely depends on the agent and hooks to deliver events in the guest operating system. To solve the aforementioned problems, based on in-memory signature scanning, we propose an agentless runtime antivirus system VirtAV, which scans each piece of binary codes to execute in guest VMs on the VMM side to detect and prevent viruses. As an external approach, VirtAV does not rely on any hooks or agents in the guest OS, and exposes no attack surface to the outside world, so it guarantees the security of itself to the greatest extent. In addition, it solves the antivirus storm problem and the rollback vulnerability problem in virtualization environment. We implemented a prototype based on Qemu/KVM hypervisor and ClamAV antivirus engine. Experimental results demonstrate that VirtAV is able to detect both user-level and kernel-level virus programs inside Windows and Linux guest, no matter whether they are packed or not. From the performance aspect, the overhead of VirtAV on guest performance is acceptable. Especially, VirtAV has little impact on the performance of common desktop applications, such as video playing, web browsing and Microsoft Office series.

The objective of this study is to search the recognition of teacher on the pattern and characteristics of the questioning sentence of the newly appointed teachers for the mathematics class through the case study for the 2ndyear teachers. The study participants' class was recorded in video and individual interview was made for 4 times. The pattern of the questioning sentence in the observed class was analyzed using the classification frame with addition of creativity related items to the classification frame suggested by Mogan & Saxton(2006). The questioning sentence and recognition on the mathematics class for the newly appointed teachers were analyzed based on the individual meeting and class materials. In result, the questioning sentence for confirmation was most frequent (69%) and questioning sentence of understanding (25%) and the questioning sentence for introspection (6%) in its priority. It was known that the questioning sentence for extending the creativity didn't make it at all. It was revealed that the participant teachers in this study used the questioning sentence pattern for fact confirmation of the student most frequently and the use of the questioning sentence for accelerating the creative thinking of the student was lacked. In addition, the teachers recognized that they manage the class oriented to questioning sentence for obtaining the concept. It was known that the education for the questioning sentence which accelerates the creativity and other thinking as well as the fact confirmation pattern is necessary through the training for the new teachers in the future.

This is a study on the application of a dialectic way of thinking in terms of design methods, and has contents about the formation of new visual and the ways of process that are triggered by cognitive introspection. A ccordingly, the study has its purposes in interpretation and recommendation of new methodological systems around dialectic principles and ways of thinking on the works of the Dutch Architecture Exhibition carried out in Korea in 2013, with the theme of "Reuse" among the aspects expanding since the reflexive modernization. Firstly, the basic features of Dutch designs were connected to dialectic ways of thinking. After studying the basic concepts of dialectics from Greek philosophies to Kant, Hegel, Marx and Benjamin, the aspects of applying them onto creative works such as art, architecture and design were methodologically systematized. Through this process, it was confirmed that the existing concepts are newly rearranged rationally, logically and scientifically based on dialectic ways of thinking rather than subjectively or emotionally. From the study of the 12 art works, it was confirmed that the value of use and potential obstacles have been used as a design solution. Also, the process which is juxtaposed with the result by itself has been expressed and causes the alienation effect. Therefore, such dialectic ways of thinking was organized into a procedural flow of contradictory recognition on situations, drive due to negativity, mutual penetration, mutual transformation, abstraction, verbalizing and creation of new concepts, and it was confirmed that such finding was valid in securing creative possibilities as 'New Uses' rather than 'Re-uses'.

In order to create a national myth and be able to control international society, America with her short national history, used popular culture to accomplish these goals. The medium fit this purpose the best was the use of superhero characters based on comics. Born and developed from the 1930s through the 1960s, which could be seen as America's national crisis era, superhero characters were thorough advocates of American justice and was perfect for the role of spreading the legitimacy of American ideology. From the 1970s, superhero characters became part of movies and became even more influential through the Hollywood's massive film industry and the box office success. American ideology in superhero characters symbolically appeared in movie costumes. Starting with Superman and Batman, the very first and typical superhero characters' costumes work as metaphors for realization of American justice. After the 1980s, superheroes were newly developed through a genre called graphic novel and the most representative piece of this genre is Alan Moore's Watchmen. In the Watchmen, which was also turn into a movie in 2009, six changed superhero characters appear ranging from a non-human superhero, villain superhero, superhero with mental disorder and superhero with sexual impotency, the characters were never-seen-before superheroes with different aspects that connote introspection and philosophical ideology. The changed type of heroes and ideology became another form of heroes, and this brought changes to character costumes that were never considered before. The superhero costumes that used to symbolize America now express different types of superhero by borrowing exotic mythical elements, undressing, pastiche and daily life clothes. The superhero characters and their changes in costumes from Watchmen imply American popular culture's introspective tendency. Amongst these changes, we need to raise our critical vision towards popular culture.

This study aimed to analyze the authenticity of dark tourism, and to discuss the possibilities and limitations of disaster tourism as an alternative type of tourism in post-modern society. For this purpose, disaster tourism related with the Great East Japan Earthquake was analyzed. After the disaster occurred, the boundaries between guests (tourists) and hosts (residents) dissolved and disaster communities emerged temporarily. This was followed by social contributive tourism, in which both guests and hosts shared their matter of life-and-death experiences, so existential authenticity became the most important motive and experience for tourism. As time passed, however, existential authenticity was reconstructed ideologically in the socioeconomic political context of disaster recovery, and replaced constructive authenticity. After all, the possibilities of disaster tourism as an alternative type of tourism based on the introspection of modernity were restricted. To discuss the underlying ethical issues of the commodification of disaster tourism, further researches should conducted to consider dark tourism as an alternative type of postmodern tourism.
