Properties and chemical bonding of wood charcoal were investigated to understand the chemistry occurring in wood carbonization. From the pH changes of wood charcoal, it is revealed that it becomes acidic to weakly basic for charcoal carbonized at about $300^{\circ}C$, whereas it turns to basic at higher carbonization temperature higher than $600^{\circ}C$. Also, the ratio of carbon atoms in the charcoal was increased with increasing the carbonization temperature, while those of oxygen and hydrogen atoms. This tendency was significant when the carbonization temperature was increased up to $600^{\circ}C$ and the ratio changes of the atoms became stable at above $600^{\circ}C$. In the changes of chemical bonding, the ratio of C-C bonding was increased and those of C-O-H and C-O-R bonding was decreased significantly. It is considered that bondings connected to oxygen atoms tends to be broken, and the ratio of C-C bonding increased. Consequently, it is expected that this change may causes occurrence of new functional groups. In addition to that, it seems to be that the chemical bondings undergo the partial decomposition, formation, and recombination steps, Because ratio of C=O bonding tended to be increased or decreased by increasing the carbonization temperature. This understanding of chemical bond changes in charcoal can be a compensative consideration on the knowledges made only by physical parameters in the properties of micro-pore which has limited to explain the phenomenon. Also, it is considered that this can be treated as a basic knowledge for upgrading and development of use of wood charcoal.

Seymour Chwast, who has worked in various fields as in illustrator, graphic designer, and art director since 1950's, opened a new possibility in the field of visual design. Pushpin Graphics, founded by Chwast and his collegues, played a vital role in experimentation based on their creativity and courage. Amazingly enough his field covers Illustration, graphic design, poster, typography, and publication. His works, in which he sa tired people or events severely using his own lanb'Uage styit', appeals public powerfully and is remembered for a long time. He gives various forms to his creative ideas throughout many fields he deals with including caricature, giving all designers fresh and b'Teat inspiration. The fact that Chwast dose not limit himself to anyone style but uses various styles freely indicates his creative thinking process. The Creative Thinking, which is embedded in all his works, is so interesting and tactful that it may fulfill the requirement of the times, which wants to see something new and epochmaking. The aim of this study is to find creativity of Chwast's new visual language and its meaning through the analysis of unique caricatures among his works based on his philosophy, creative work process, and, particularly, creative thinking.

In the 21st century, there will be a robot revolution. Only several years ago, industrial robots were the mainstream in the robot market; however, diverse type of robots are currently entering into our daily lives for various purposes, and the robot that thinks and behaves very similarly to human will appear in the near future. However, there is a critical view about the robot period. This means that the robot revolution will change even the framework of our entire society and human life style, and it is necessary to have robot education. It is necessary to start robot education in the elementary school curriculum with a view to enhancing interest in basic science and scientific technology and cultivating creative talents who may adapt themselves to a robotic society. However, there is no systematic robot curriculum owing to insufficient perception of the need of robot education and the educational utilization of robots. Under these circumstances, robot education is largely dependent on education for students with special talents and aptitudes run by private organizations. This paper conducted the following research in order to develop a robot curriculum in education for the gifted elementary students of computer science. First, the paper identified problems by analyzing the robot curriculum from a micro perspective after selecting three organizations that are relatively well perceived out of private organizations that operate robot education for the gifted elementary students of computer science. Second, the paper developed a robot curriculum in education for the gifted elementary students of computer science based on the framework of a robot curriculum run by private sector. Third, the validity of the robot curriculum developed in this paper was verified by a professional group comprising mainly persons in charge of robot curriculum development at private sector and lecturers for robot education for the gifted elementary students of computer science.

About 75% of software security incidents are caused by software vulnerability. In addition, the after-market repairing cost of the software is higher by more than 30 times than that in the design stage. In this background, the secure coding has been proposed as one of the ways to solve this kind of maintenance problems. Various institutions have addressed the weakness patterns of the standard software. A new Korean programming language Saesark has been proposed to resolve the security weakness on the language level. However, the previous study on Saesark can not resolve the security weakness caused by the API. This paper proposes a way to resolve the security weakness due to the API. It adopts a static analyzer inspecting dangerous methods. It classifies the dangerous methods of the API into two groups: the methods of using tainted data and those accepting in-flowing tainted data. It analyses the security weakness in four steps: searching for the dangerous methods, configuring a call graph, navigating a path between the method for in-flowing tainted data and that uses tainted data on the call graph, and reporting the security weakness detected. To measure the effectiveness of this method, two experiments have been performed on the new version of Saesark adopting the static analysis. The first experiment is the comparison of it with the previous version of Saesark according to the Java Secure Coding Guide. The second experiment is the comparison of the improved Saesark with FindBugs, a Java program vulnerability analysis tool. According to the result, the improved Saesark is 15% more safe than the previous version of Saesark and the F-measure of it 68%, which shows the improvement of 9% point compared to 59%, that of FindBugs.

Objectives : This study examined the characteristics and differences of PAI(Personality Assessment Inventory) profile between compensation-seeking(CS) and treatment-seeking(TS) patients with traumatic brain injury(TBI) and assessed the clinical meaning of the characteristics and differences of profiles between the two groups. Methods : 36 TBI patients who visited the Wonkwang University Hospital were selected. The patients were categorized as compensation-seeking TBI patients(n=22) and treatment-seeking TBI patients(n=14). The PAI scales and subscales were used to compare differences between two groups. t-verification for each variable and comparison analysis were performed. Results:In validity scales, CS group showed significantly higher NIM scores and lower PIM scores than TS groups. In full scales, CS group showed significantly higher SOM, ANX, ARD, DEP, and SCZ scores than TS group. In subscales, CS group showed significantly higher SOM-S, ANX-A, ARD-P, DEP(-C, A, P), (MAN-I), PAR-H, SCZ(-T, P), BOR(-A, N), and ANT-S scores than TS groups. In supplementary scales, CS group showed significantly higher SUI, NON and AGG-P, and lower RXR scores than TS group. Conclusions:There were significant differences in PAI scales with validity scales, some full and subscales according to compensation seeking status in TBI patients. The CS patients tended to exaggerate their symptoms on PAI, and showed higher scores representing somatic preoccupation and emotional distress. These results show the usefulness of PAI in reflecting the significant psychological differences between two groups.

This study examined the problem of entrepreneurship education in Korea, which equate entrepreneurship with startups, unlike the global trend of approaching entrepreneurship with a broad concept. On the basis of overseas cases such as European Union and OECD, this study derived the need for entrepreneurship education from the perspective of thinking and behavioral patterns. In addition, Q methodology was used to reason out various recognition patterns and approach solutions for problems of entrepreneurship education in Korea, such as awareness of the need for entrepreneurship education in concepts separate from start-ups, reasons for infertility, and why it is difficult to activate. This approach was conducted for educators and educatees that carries out entrepreneurship education in Korea. In conclusion, there were four types of subjective perceptions about the difference of entrepreneurship education and startup education, and three types were recognized for the need to differentiate entrepreneurship education from startup education, and the two types that made up the upper majority strongly supported the need for entrepreneurship education to be implemented individually. According to the conclusion, this study proposed the development and spread of common teaching materials made by the Ministry of Education and Ministry of SMEs and Startups, which is the competent Ministry, to train professional teachers, training methods, and continuous refresher education. It also proposed that there should be a social atmosphere for eliminating rejection of entrepreneurship not only among the youth but also the adult population, and for continuous awareness of concepts that can be applied within the organization and the community, and that a policy basis is required to do so.

The Fourth Industrial Revolution foreshadows radical changes in our lives. In the era of the fourth industrial revolution called the digital revolution, individualized learning based on ubiquitous learning is emphasized. The contents of learning will be centered on procedural knowledge rather than narrative knowledge, and fusion education in which boundaries between learning domains are broken down will be achieved. First of all, learners in the fourth industrial revolution era should have critical thinking and problem solving abilities. Metacognition based on self-control and cognitive flexibility is important for effective self-directed and active learning. Creativity-based collaborative activities, social vision skills, and social and emotional skills are also important competencies. Therefore, in order to provide individualized learning contents to learners in the fourth industrial revolution era, they should be transformed into learning paradigm based on personal characteristics such as learners' self-efficacy, interest, curiosity and creativity. In addition to this, evaluation forms should be diversified according to changing teaching and learning methods. In order to cultivate teachers to lead such educational innovation, it is necessary to reconsider the teaching capacity. Teachers should be able to construct creative lessons by skillfully exploiting technology in future learning environments. In addition to this, it should also have the ability to collaborate and cognitive flexibility to converge with other academic disciplines. Along with these discussions, we proposed the need for policy intervention along with changes in education.

A general sequence of moral instruction in elementary school is advanced to understanding of contents, application of understanding, reflection of application. The understanding of contents as first stage of instruction is related with abstract moral concepts. A model of concept analysis as one of the moral instruction models could be applied to understand on abstract moral concept. We can find rationale of that model from the 'analysis of concept' that is proposed by John Wilson. His 'analysis of concept' is thinking technique based on informal logics of ordinal language. These technique is constituted of 'Isolating questions of concept', 'Right answers', 'Model cases', 'Contrary cases', 'Related cases', 'Borderline cases', 'Invented cases', 'Social context', 'Underlying anxiety', 'Practical results', 'Results in language'. And these techniques could be categorized some of stages like finding a concept for analysis, finding a cases for understanding, concerning on the contexts about using context, concerning on the verification of defined concept. But it has difficulties that directly applicate these stages and technique to elementary school students. For instruction in elementary school, teacher should be translated these terms about each stages and technique to terms suited for students. And it is good for students that these activity can inspire students' interests. In this thesis, I'm trying to translate original terms about concept analysis technique to terms that elementary school students can understand. And then, I'm intending to propose of moral instruction method about truth telling as a example.

After the collapse of the Seongsu Bridge in 1994, the ｢Special Act on the Safety Control and Maintenance of Establishments｣ was enacted in Korea, and many efforts have been made in the field of safety inspection and maintenance of facilities. Among these facilities, a total of 33,165 bridges, which account for the largest share next to buildings, are currently in use, and 28,150 bridges of type 2 and 3 account for about 85% of the total. However, compared to the relatively more important type 1 bridges, type 2 and 3 bridges, which occupy most of the bridges, have insufficient maintenance status regarding inspection and diagnosis. This reason appears in the subjective judgment and records of the inspection performer when performing inspection and diagnosis of bridges, and in the inspection and diagnosis report form that has not been systematically established. Therefore, in this study, we intend to derive an improvement (draft) of the inspection and diagnosis report that can be systematically and continuously utilized by correcting and supplementing the problems of the existing inspection and diagnosis report.
