3D printing has grown tremendously as the most noteworthy new technology in the manufacturing industries. In addition, the rapid development of computer science technology with 3D printing has created a new paradigm called Fractal Geometry, or a new form of digital art. This study explores the formative characteristics of 3D printing jewelry based on presentation of fractal geometry by classification of 3D printing jewelry's morphological types that except for producible shape with traditional mold manufacturing methods. The results of the study are as follows. The morphological characteristics of 3D printed jewelry are divided into their constitutive shapes by the repetition of the unit. The organic shape determined by superposition or overlapping, the systematic shape by distortion caused by distortion, and the variation in scaling by scaling. The formative characteristics, which are drawn from a study on the shape expression of 3D printed jewelry design using fractal geometry, consist of continuity, geometrical characteristics, and exaggeration. Continuity creates a new and self-assigned new space through a recursive structure through a cyclic structure that is formed along a single directional basis. The geometry of the geometry forms a three-dimensional and constructive structure comprised of the same size and structure of the same sized unit under the mathematical order of the geometry of Fractal's geometry. Exaggeration demonstrates the informal beauty and the maximization of the shape by expanding the scaling or superposition of a unit, by scaling the scale or he distortion of the units.

The purpose of this study is to analyze the costume in $\ulcorner$The Goddess Abides$\lrcorner$ of Pearl S. Buck by applying "Dramaturgical Analysis" of Erving Goffman. The frame of analysis is the dramaturgical conception of Goffman that he expressed in $\ulcorner$The Presentation of self in Everyday Life (1959)$\lrcorner$. Among the conception, I analyzed by applying 'performance', 'technique of impression management', 'region and region behavior' which can be used for studying and costume behavior. The following is the summary of my study. First, the performance means the performer's behavior and the procedure of impression management if face to fact interaction, which includes personal front and setting. Setting is mainly a house on the Mt. in Vermont. The time is Winter. The personal front includes appearance and manner. actors and audiences form impression through persional front. And Istudied the performance of the actors (or actress), Edith, Jared, Edmond, Edwin, Amelia, June. As for technique of impression management, I cold observe that a varieth of that were being used, such as the most general one that Edith wants to look beautiful by making god appearance, or she sometimes try not to look beautiful And when Edith meets Jared, sometimes she changed her clothes, but other times she doesn't do that. As for region and region behavior, there appears the distinction of region and a lot of expressions about clothes related to the distinction. I could observe the expressions showing the movement from front to back and from back to front. Especially I could observe the behaviors that can be occured only in back region in everyday life, that is bathing, changing clothes, making up, checking their appearance before the mirror. Like above when I analyzed $\ulcorner$The Goddess Abides$\lrcorner$ of Pearl S. Buck by Goffman's Dramaturgical analysis, I could find out that the theory was very useful to the analysis of the costume behaviors of the characters.

As the recent demand for human resources in science, technology, engineering, and mathematics (STEM), the development of professional STEM teacher is called worldwide. It is becoming a critical need in teacher education in order to educate student teachers, and prepare pre-service and beginning teachers for high quality of teaching competency. To promote the competency for $21^{st}$ century STEM teachers, the epistemology of technological pedagogical content knowledge (TPACK) is currently considered as the essential qualities of knowledge for highly qualified teachers. The aim of this study is explore the effect of case-based learning approach on TPACK competency of pre-service STEM teachers. In order to develop the pre-service teachers' competency regarding effective integration of technologies into teaching specific content areas, a series of innovative case study teaching in science and mathematics was presented to 43 participants of pre-service physics, chemistry, biology, mathematics, and computer teachers during a course of information and communication technology (ICT) in Education at Khon Kaen University, Thailand. After finishing a case presentation, the pre-service teachers were encouraged into a forum of critical open discussion by considering the potential impact of the case and the TPACK framework. They were investigated instructional design competency of using ICT tools into student learning process and their personal beliefs about ICT in educational process both before and after. The participant's reactions and learning was evaluated by using a self-reported questionnaire and an implementation log of content-specific learning process design, respectively. Results showed a change of their beliefs and the transformation of their TPACK competency in STEM teaching. In an effort to better serve the needs of high quality STEM teachers, the results of this study illustrated that the competency of TPACK could be particularly considered as a core attributes for future STEM teachers. By the way, case-based learning approach can play an effective part in preparing and professing the TPACK competency for STEM teachers.

On the threshold of year 2000, the elderly account for more than 7% of the whole population in Korea, which means that the nation is greeting welcoming an aging society. Accordingly, it is expected that silver businesses and services targeted at the silver generation will prosper with "silver advertising design" becoming active. Under such circumstances, this study was aimed at reviewing the recent silver marketing advertisements in terms of their cultural and moral implications, and thereby, redefining and reestablishing the status of silver consumers to help them find their identity, aware of marketing activities and therewith, establish their "consumer sovereignty". This study consists in large of 5 chapters. The introduction parr describes background, purpose, method and scope of the study. The first chapter reviews the silver marketing theories. The second chapter classifies the silver marketing advertisement positioning of four style - upper classes style, effloresce progress style, self- sufficiency style, dependent style - and reviews the expression strategy of each positioning. The third chapter examines the domestic conditions of silver marketing advertisements for each positioning type classified. The fourth chapter designs the ′creative′of silver marketing advertisements and suggests the methods thereof. The analysis of ′creative′was tested in terms of graphic gestaltung, and how the sliver marketing advertisement positioning should be discerned depending on silver generation consumer′s characteristics was discussed. The fifth chapter puts forwards the suggestions for the ′creative′ strategies to enhance the effects of the silver marketing advertisements, based on the preceding discussions. In addition, the Perspective into the keyword of 21 st century or "silver design" is discussed, together with the limitations of this study. It is hoped that this stuffy will be conducive to our efforts to face the upcoming′age\ulcorner society′more effectively. To this end, this study discusses the "silver advertising design" in light of ′societal concepts′and ′customer-oriented value′, and thus, explores some creative presentation strategies whereby individual companies interests and social or public interests can be compromised through ′creative activities′ and ′equal-value consumerism′ for an ultimately effective management strategies for silver businesses and services.

The purpose of this study was to explore the reasons why college students use Facebook and the ways in which they feel of social presence while using Facebook. In fact, the study aimed to specify the links between motivations for using SNS and a sense of 'being together'. The findings of this study suggest that major motivations of SNS use were social interaction, entertainment, self-presentation, and information-seeking. Specifically, results from a survey of 280 respondents revealed that college students used Facebook to seek maintenance and connection with friends, to express themselves, to get information about school activities, and to be entertained. These findings are consistent with the existing literature regarding SNS as a primary channel to maintain the existing social relationships among college students. The study also found that all motivation factors, except information-seeking factor, were positively and significantly related to social presence. The strongest correlations were between social presence and Facebook use for social interaction and entertainment needs. It seemed that users who seek social interaction and entertainment needs are more likely to feel a sense of being with others while users who seek to get information are less likely to feel a sense of social presence. These findings implied that to some extent, a sense of social presence occurs in the context of Facebook and that the experience of social presence depends on what college students seek from Facebook use. In addition, the results showed a positive relationship between Facebook use and social presence; the more college students use Facebook, the more they are likely to experience sense of social presence. Given that Facebook provides college students with a place where they can share thought and feelings among friends, it can be concluded that Facebook contributes to the sense of belonging among users. And such feeling may enhance a sense of presence with others while using Facebook. These findings suggest that uses and gratifications researchers should consider the concept of social presence as an important variable in explaining what audience members do with media.

The purpose of this study is to develop teaching and learning materials for the mathematics project inquiry subject. Since this subject is newly opened in the 2015 revised mathematics curriculum, there are no textbooks and materials. Hence it is required to help teachers plan lessons of the mathematics project inquiry subject. For this study, developing directions and objectives are established. Ten hours of lesson plan and teaching and learning materials are also developed for the two themes of 'big data' and 'industrial mathematics'. Suitability and validity of the developed material are verified positively from a survey of 8 teachers and 2 professionals. The detailed result findings are as follows. First, teaching and learning notes are suggested for each lesson plan. They are comprised of building inquiry plan, doing inquiry, summarizing results, and presentation. Second, driving questions of each theme are developed as "What is the big data and where is it used for ?" and "How various is the use of the industrial mathematics ?" respectively. Third, poster-types of each project product are developed. Fourth, three inquiry activity sheets and examples which are theme selection, inquiry plan, and group activity are developed. Fifth, 4 assessment sheets of self, peer, group, and teacher-use are developed.

The purpose of this study was to observe school education system, higher education, and fashion education in Germany to find a good model for an desirable future education to lead a creative students in Korea, thereby reshaping curriculum. We also analysed the curriculum of the fashion design offered in Hochschule Pforzheim and Berlin University of Art. We used secondary data collection by literature reviews of articles and web sites on the internet. Results of this study are as follows: German school and education system oriented with differentiation even though there are variety of them. Students can select their education system, considering work field and their own life & humanities. Various fashion education institutions were found to have their own education concept to enhance creativity with different system. Our results of analysis of the fashion design program of Hochschule Pforzheim and Berlin University of Art show their creativity education in their curriculums with module basis. Two universities have a differentiate education direction for the same aim to do creative design study and research. We realized that students learn and get the knowledge and apply to the field with a long term internship, communication skill and presentation development courses. Project based modules enable students to be creative, and active human. Strong design basis, and humanities disciplines will support people to creative design works. These two universities offer a good model of program to build up self education drive, academic and practical ways of training, and project based, internship, etc.

Subcutaneous emphysema on the head, neck, and pneumomediastinum are, abnomal but well-documented, presence of air in the subcutaneous tissue and mediastinum, and can be diagnosed by palpation of the soft tissues, lateral or crosstable cervical radiograph and upright chest radiograph. The common clinical features of cervical emphysema and pneumomediastinum were facial and cervical swelling, presence of crepitation on palpation of the soft tissue, and retrosternal pain. Subcutaneous emphysema may arise from use of high-speed air turbine drills, facial trauma, trachea bronchial tear, endotracheal intubation, mechanical ventilation, chest injury, tracheostomy, following Lefort I osteotomy, and spontaneously. Symptoms of subcutaneous emphysema and pneumomediastium are generally self-limiting and eventually subside with conservative therapy. As we report a case of traumatic subcutaneous emphysema and pneumomediastinum after facial injury with clinical presentation and treatment consideration.

This study was conducted to explore the possibilities of educational use of social curation service, which is the third-generation social networking service called the "matters of interest type." To this end, the study selected nine college students, then have them use social curation service for about 50 days, and analyzed their responses by performing the focus group interview (FGI). As a result of the analysis, social curation service was found to have strong points, including collection of various types of information, classification and summary through creation of my own category, possibility of constant updating of matters of interest, and reduction of relative deprivation compared to existing social networking services. To solve these issues, constant promotion was needed. From the aspect of educational use, it was found that social curation service had possibilities for individuals and teams: For individuals, the service enabled voluntary search and use of information, configuration of my own data, and facilitation of self-directed learning. For teams, it enabled discussion and presentation activities through sharing.

This study was to develop an issue-centered small-group competing-debate program for the Introduction to Traditional Korean Medicine curriculum in School of Korean Medicine, Pusan National University. This debate program has student-, process- and depth-focused characteristics with critical-thinking perspectives. We employed random assignment of the position, submission of the presentation data prior to the debate, and individual result report to assess debate quality and participation of the students. This program was effective educational program for the understanding of traditional Korean medicine-related subjects. 56.7% of the students showed "Yes (>7 out of 10)" to the achievements of the program objectives, and 62.2% reported "much helpful (>7 out of 10)" to the usefulness of this program. We also found that this debate program would be specifically useful for critical reviewing of subjects which students have known superficially. This study will contribute to the development and improvement of efficacious educational curriculum for Korean Medicine by providing practical reference and template with self-directed group debate program.
