Signs of the street and scenes of the nature(tree) popping up like a still screen in a monotonously repeated routine, as if waiting for something by chance, characters appearing and disappearing without special meaning, advise you to get away from cliché meetings and breakups while repeating it. The images of people returning to their places without presenting any conclusions highlights the coincidences and unexpectedness of everyday life, but are so familiar that it is easy to be overlooked, it brings us to experience the potential of everyday unfamiliarity in such moments. The actor's performance, which deviates from the practice of well-organized characters, is improvised (unplanned and uncoordinated) emphasized on the scene and expresses the everyday nature of his differentiated character freely like the reality as if he were locked up in a film structure but not confined to it, and as if he got used to the everyday life. Also the repeated words and actions of characters, and unpredictable changes of emotions, centered by the encounters and conversations of this film of Hong Sang-soo, everything that is presented in the background of everyday life in its form, let's us pay attention to the meaning and what to be found in the film. In addition, director Hong Sang-soo, who creates a story after selecting actors to reproduce this daily process in a realistic manner, sets new relationships between the characters and the actors, presenting a new method of realistic expression, through the actor who repeatedly appears in the film. This study analyzes the everyday characters and acting of the film based on director Hong Sang-soo's directing style.

Purpose: Resonance Frequency Analysis(RFA) technique can be used as an effective method in measuring the implant stability and documenting the clinical results. This technique also determines how stable the implant is before performing a prosthetic practice. Having become one the guidelines of the implant therapy whose final objective is the immediate loading, the $Osstell^{TM}$ mentor is giving a lot of information to the clinicians recently. In this communication, experiments were performed to investigate how reliable the measured ISQ values by $Osstell^{TM}$ mentor are, and to see if those are also stable even after sterilization. As five objectives: 1) How stable measured ISQ values after fixation $Smartpeg^{TM}s$ for 400 times. 2) How stable measured ISQ values after 'attach-detach'$Smartpeg^{TM}'s$ for 400 times. 3) How stable measured ISQ values after clinical sterilization methods. 4) How stable measured ISQ values after repeatedly sterilization in autoclave for 10 times. 5) What is the critical temperature which is lost the magnetism of $Smartpeg^{TM}$. Materials and Methods: Clinical sterilization methods(Autoclave sterilization, Dentistar sterilization, Ultra violet sterilization, Vacuum dry unit sterilization, Boiling water sterilization, combined $H_{2}O_{2}$ and Alcohol sterilization).$Smartpeg^{TM}s$. D3 Block bone($3{\times}9{\times}2cm$). Osstem implant(${\emptyset}4.1$-10mm).$Osstell^{TM}$ mentor. Individual experiment was used 8 number of $Smartpeg^{TM}s$ and they had measured to ISQ values of before experiment and after experiment. Results: 1. The measured ISQ values did not change after fixation $Smartpeg^{TM}s$ for 400 times. 2. There was no significant changes in the measured ISQ values of 'attach-detach $Smartpeg^{TM}s'$ for 400 times. 3. The measured ISQ values did not change after the usual clinical sterilization methods. 4. The measured ISQ values did not change after sterilization in autoclave for 10 times. 5. It was impossible to exactly measure the critical temperature which is lost the magnetism of $Smartpeg^{TM}s$. But, the results was resulted to lost its magnetism in higher temperature than $150^{\circ}C$/10 minute. Conclusion: The measured ISQ values showed insignificant differences in case of no changes in the magnetism of the $Smartpeg^{TM}s$. It seems that the $Smartpeg^{TM}s$ can be used repeatedly in every measurement if the original magnetisms of the $Smartpeg^{TM}s$ can be recognized. There seems to be no significant changes in the measured ISQ values of 'attach-detach $Smartpeg^{TM}s'$ only if the screw pitches were unimpaired. The clinical sterilization methods seems acceptable because the result was resulted to lost its magnetism in higher temperature than $150^{\circ}C$/10minute.

NEIS (National Education Information SystTem) provides educational information to parents while students are not able to have the direct access to their own academic information. Students filed their request to the National Human Right Agency. The objective of this study is to investigate the feasibility of students direct access to their own information and how to do it. In detail, online survey was conducted from 3,300 students, teachers and parents who are the stake holders of student information service on NEIS regarding whether they are for it, if so how to do it. The result indicated that students, parents and teachers are all positive in that order. It is unexpected that teachers who need to input and are responsible for the accuracy and reliability for student information are also for it. Although the human right law suggests all students have the right to direct access to their own information, the order of operation can be from secondary school level if the operation can not be done all at the same time. The range of information provided through this service is in principle the same as what parents can access except the counseling information.

The goal of the study is to provide a new type of audio-visualization method through case analysis and work production based on Polysomnography(PSG) data that is difficult to interpret or not familiar to the public. Most art works are produced with conscious actions during waking hours. On the other hand, during sleep, we get into the world of unconsciousness. Therefore, through the experiment, want to discover if could get something new when we were in the subconscious state, and if so, wondered what kind of art could be made through it. The study method is to consider definition of sleep and sleep data first. The sleep data were classified into normal group and Narcolepsy, Insomnia, and sleep apnea by focusing on sleep disorder graphs that is measured by sleep polygraph. After that, I refined and converted the acquired biometric data into a text-based script. The degree of sleep in the text form of the script was rendered as a 3D animated image using Maya. In addition, the heart rate data script was transformed into a midi format, and the audition was implemented in the garage band. After Effects combines the image and sound to create four single channel images of 3 minutes and 20 seconds each. As a result of the research, I made an opportunity for anyone easy to understand the results, having difference with the normal data, through art instead of using difficult medical term. It also showed the possibility of artistic expression even when conscious actions did not occur. Through the results of this research, I expect the expansion and diversity of artistic audiovisual expression of biometric data.

If digital forensic investigators can utilize file access logs when they audit insider information leakage cases or incident cases, it would be helpful to understand user's behaviors more clearly. There are many known artifacts related to file access in MS Windows. But each of the artifacts often lacks critical information, and they are usually not preserved for enough time. So it is hard to track down what has happened in a real case. In this thesis, I suggest a method to utilize SACL(System Access Control List) which is one of the audit functions provided by MS Windows. By applying this method of strengthening the Windows's audit settings, even small organizations that cannot adopt security solutions can build better environment for conducting digital forensic when an incident occurs.

This paper was written for the purpose of using as the theoretical basic data of judgment in the situation that there is a growing demand for intelligent design theory to be taught in public schools along with evolution theory. In order to verify the possibility that intelligent design theory, which has little empirical evidence unlike evolutionary theory, could be a scientific theory, what intelligence is and whether the trace of intelligence is actually found in nature was confirmed through literature. If intelligent elements, which are traces of intelligence in nature, are discovered empirically in nature, then intelligent design theory can be recognized as a scientific theory and can also be taught in public schools. The identity and traces of intelligence were found in relevant literature and the traces are found not only in various artificial products derived from human beings such as thinking, knowledge, and civilization, but also in all phenomena of nature. Based on these results, this paper provides a discussion on how the evolutionary theory and intelligent design theory should be handled in the field of school education, as well as how to resolve the conflicts between evolutionary theory and intelligent design theory.

I propose a prescription transmission system based on XML in this paper, and it is not to attach a former signature to only a XML document for encoding of XML/EDI, and it is construction, one with the prescription transmission system which is safer with what use a way to attach a digital signature to DTD. I defined sub element to manage information prescription DTD defined prescription information, patient information, medical care organ information, prescription details information, compounding of medicines details information element according to for each a component of a prescription I went along, and to have looked up, and to have obeyed information transmission at he low rank. I read a DTD file for safe prescription transmission, and I do element or property, the entity which I do it, and is extracted here, and Pasing is saved in a table while being a field. If Pasing is finished, I read and lift a hash table and carry out message a digest. I compose it with an early private key and create a digital signature.

Modern museum, along with the basic roles of a museum that display to the public through the exhibition of physical evidences that collected, preserved and researched about human environment, it is changing in a way to appropriately fulfill the desire of new culture of the public and to fit the paradigm of the digital era. Diversification of expression method using multimedia played a big role in effective meaning delivery and technology development made possible for interaction-able of digital media build up and application to made possible of interactive communication for visitors. If the main purpose of the past museum exhibition was the delivery of information and knowledge, modern museum's exhibit has been identified as the purpose being diversified through the use of digital media. Exhibition planner, as for museum exhibition that used many characteristics of the digital media as mentioned above, should plan so that past unfamiliar relic can communicate with us living in the modern society. But obsessive usage of the digital media should not shade the interest of the visitors towards the relic in overall exhibition; and what is most important is that other than the exhibition and exhibit, enforcement of translation through systematic coherent approach and its appropriate digital technology and creative application and harmony are more important.

There is no single definition of mathematical creativity. But creativity is a key competency to adapt and live in the future. So, there are so many attentions to develop students' mathematical creativity in school mathematics. In special, mathematical problem posing activity is a good method in enhancing mathematical creativity. The purpose of this paper is to analyse on the students' mathematical creativity using problems which are made by students in problem posing activities. 16 children who consist of three groups(high, middle, low) are participated in this study. They are trained to make the problem by Brown & Walter's 'What if not' strategy. The results are as follows: Total creativity is proportional to general achievement levels. There is a difference total creativity between items contents. The number of problems differs little according to the general achievement levels. According to the qualitative analysis, students make the problems using the change of terms. And there is no problem to generalize. Based on this paper, I suggest comparing the creativity between problem posing activity and other creative fields. And we need the deeper qualitative analysis on the students' creative output.

Certified e-Document Authority keep it with protection legal as a system a guarantee and identifies originality of an e-Record, It presume to be authenticity e-Records and contents of an e-Record prove what was not changed. But, e-Records has high medium degree of dependence and loss danger of information has very high problems. In addition, Because correction(attachment and deletion) and a revision of information are easy, a problem for integrity and the originality of an e-Record is caused. Existing system show the following inefficient. For the originality guarantee, an existing e-Documents encryption method accomplishes a encrypted process of a whole document with a symmetric key, if the information revised midway, the whole documents content must accomplish re-scanning and re-encryption process again. To get over such inefficient, this paper maximize efficiency which occurred at the time of partial information revision request by encryption and managing using the link information based on the linkage characteristics of the each page on the registered requested e-Documents, It was able to increase security configuration by minimizing problems on an information exposure through increasing complicated of the key management.
