The motion-graphic have been a more important factor in image illustration and typography since the development of visual culture was advanced. Therefore the visualized case of intented content with the creative typography is easily seen in television CF, movies and web pages. They suggest that variable factors such as language, time, shape, motion, color and sound should be applied and produced to motion typogaraphy. But the physiologic features as sex, age, health status, illness and physical size have an important effect in the communication process. So, the more effective result were gained than the fast-developing other mass media if these features were applied to the motion typography with semi-language speciality.

This study tries to compare the noise difference by various surface treatments and to propose appropriate tinning methods. As literature reviews, longitudinally tined pavement is effective to reduce noise made between tire and pavement surface. Various surface treatments were applied to some sections of test road. In case of car, about 2$\sim$3dB(A) was reduced in the section of uniform space 18mm longitudinal tinning. The peak frequency point for truck case happened between 200 and 600 Hz. The maximum noise of car was measured at about 1000Hz. Therefore, it Is proved that surface treatment methods can have a large affect on noise generation. With a result that friction test, the transverse tined pavement showed better frictional characteristics than the longitudinally tined pavement, but as a whole it came out satisfactory result. Results from this study are of early age, so it is required to check the performance continuously.

The RC corbels with the ratio of shear span-to-effective depth less than 1 are commonly used to transfer loads from beams to columns. The ultimate strengths and structural behaviors of RC corbels are controlled by the shear span-to-effective depth ratio, strength of concrete, shape and quantity of the reinforcement, and geometry of corbels. In this study, a simple indeterminate strut-tie model reflecting all characteristics of the ultimate strengths and complicated structural behaviors is presented for the design of RC corbels. In addition, a load distribution ratio, defined as a magnitude of load transferred by a horizontal truss mechanism, is proposed to help structural designers perform the design of RC corbels by using the strut-tie model approaches of current design codes. The ultimate strengths of 30 RC corbels tested to failure are evaluated by using the ACI 318-05's strut-tie model code for the validity check of the proposed indeterminate strut-tie model and load distribution ratio.

This study aims to analyze typographic expressions used in recent fashion trends from the perspective of conceptual art and thus identify a variety of meanings. Towards this end, theoretical considerations were made vis-à-vis the main concepts of research, such as typography and conceptual art, and the ready-made, documentation, intervention and language, which are the expressive features of conceptual art, were applied to fashion typography as analytical frameworks. The results are as follows. The ready-made appears in a way that borrows or transforms the visual identity of other brands, and documentation is utilized in a way that lays tautological or contradictory texts together. Intervention arises, while leading to more complex layers of meaning when borrowing the visual identity of the brand, which is conceptually irrelevant. The language is expressed as statements about contemporary social issues, such as environmental protection, ethical consumption and gender problems. Based on the findings of this study, it can be confirmed that in fashion design, typography serves as an effective marketing tool and a medium of social statements. Moreover, it can expand into the possibility of generating new meanings as a novel way of visual expression.

Before the digital age, the main tools used for printing out letters were pen and brush. Therefore, forms and styles of the languages modelled out during the age also revolved around the pen and brush. However, new tools and techniques introduced in the digital age to express typography put this limit in the shade. In other words, the user can make expressive and experimental typography and typefaces quickly and easily, by learning and utilizing new tools efficiently. As such, this study is to explore those cases, to understand characters and meanings of expressive and experimental typography within the context of typography history, to introduce a new tool, 'Scriptographer' developed by means of the open-source scripting plug-in for Adobe Illustrator, and to discuss the advantages, disadvantages and applicability of this tool. Further on, through case analysis of successful preceding projects, the researcher arranges a practical foundation, and estimates the practicality of this research through experimental typography series, Rush Type and Celestial Type, created by using Scriptographer.

Typography is a subject of fundamental principle and considerable importance to the practice of design and visual language. In Typography education, we need to teach student with systematic, logic and holistic view prior to intuitive way. It must be emphasized as a foundation to all graphic design students who are familiar with digital media. despite the fact that high technology has invaded th design profession and the importance of learning how to deal with these new possibilities has grown, technological processes are not substituted nor are they excuses for not learning basic principles of Typography. Technology is merely and extension of these skills. The logic is objective and the intuition is subjective. Visual system exercises the student's ability to work objectively in thought and in method. Visual system presents the idea that logic and intuition can work together to give stronger results in problem solving than either can alone. I critically analyzed that what is system and how can we develop visual system which can be adapted to Typography education. I also have investigated visual system to find the possibility and flexibility in Typography education.

Melanin pigmentation in human skin is a major defense mechanism against ultraviolet light of the sun. Tyrosinase(EC 1.14.18.1) plays a key role in the biosynthesis of ultraviolet of melanin. This is why much researches have been focused on its regulation in controlling the epidermal melanization. We have found that the water-extract of Banha(Pinelliae ternate B.), an oriental medicinal plant, has no tyrosinase inhibitory activity, but does inhibit the melanin biolsynthesis in B16 mouse melanin cells. We also found that Banha extract lowers the tyrosinase activity in cultured cells. To elucidate the action mechanism of Banha extract we have investigated its effect on the tyrosinase mRNA level using reverse transcription-polymerase chain reaction technique. It was revealed that Banha extract reduced the tyrosinase mRNA level in dose dependent manner; when B16 mouse melanoma cells were cultured with 2mg/ml and 5mg/ml of Banha extract, there were 20% and 44% decrease in tyrosinase mRNA level, respectively. These data suggest that the Banha extract exerts its melanogenic inhibitory effect through the transcriptional regulation of tyrosinase mRNA.

치과용 임플란트 실패의 주요 원인은 임플란트 표면에 부착되는 세균의 침착의 결과로 생기는 임플란트 주위염이다. 구강 내에서 세균성 치태의 침착은 치태가 부착하는 기질 표면의 물리적 성상과 타액성 피막의 성분에 영향을 받으며 형성된 피막의 유기질 성분의 차이가 치태의 성분과 병원성에 영향을 미친다. 최근 연구에 의하면 생체재료의 표면에 침착되는 치태세균은 사용되는 재료에 따라 특이한 세균 침착을 보이며 이는 초기 타액성 피막의 차이에 의한 것으로 알려져 있다. 이 연구의 목적은 플라즈마분사법으로 표면 처리된 타이태늄 임플란트에 흡착되는 타액성 단백질 피막의 특성을 정성적인 방법으로 분석하는 데 있었다. 법랑질 조각과 플라즈마분사법으로 표면 처리된 타이태늄 임플란트를 스프린트에 치실을 이용하여 연결한 장치를 구강 내 장착하여 2시간 동안 피막이 침착되게 한 후 피막을 분리 추출하여 냉동 건조시켰다. 재수화 과정을 거치고 나서 전기 영동법과 Western transfer 분석을 통해 단백질 성분에 관한 분석을 시행하였다. 사람의 총 타액과 이하선 타액 및 악하선-설하선 타액을 수집기를 이용하여 채취하고 같은 방법으로 처리한 후 성분분석을 실시하였다. 피막 흡착 전후의 표면변화를 주사전자현미경을 이용하여 관찰하였다. 실험결과 타이태늄 임플란트에 흡착된 피막은 법랑질 표면의 피막과는 다른 단백질 성분을 가지고 있었으며, 주로 악하선-설하선 타액에서 유래하였다. 임플란트와 법랑질 표면 모두에서 흡착된 피막에는 아밀라제, 분비성 면역 글로불린A 및 락토페린이 존재함을 알 수 있었으나 법랑질의 경우는 blotting이 약하게 나타났다. 주사전자현미경 관찰결과 시편의 표면에 균질한 피막이 덮고 있었으며 세균의 부착은 거의 관찰되지 않았다. 이상의 실험 결과들을 통하여 플라즈마분사법으로 표면 처리된 타이태늄 임플란트 표면에 부착된 타액성 단백질 성분은 법랑질과는 차이가 있음을 알 수 있었으며, 이러한 차이는 치태세균의 종류 및 병원성에 영향을 미칠 것으로 생각된다. 법랑질과 타이태늄 임플란트는 기질과 표면구조가 다르므로 표면에 형성 되는 치태성분도 다르다는 사실과 본 연구 결과를 종합하여 볼 때, 타이태늄 임플란트 표면에 흡착되는 초기 타액성 단백질의 성불이 타이태늄 표면에 침착되는 미생물 군의 조절에 중요한 역할을 가지고 있으며, 임플란트 치료 시에 올바른 치태 관리법의 교육을 통하여 환자 스스로 적절한 관리를 하도록 함으로써 임플란트 치료의 성공률을 높일 수 있을 것으로 생각된다.

TYME is an interactive typography program based on the ephemeral nature of time. It is a text based poetic tool, built with Processing. This project is presented as a performance that utilizes a computer with a display screen, a projector, and speakers. As the user types, white characters appear, flow on the score on the screen and trigger jazz sounds, then characters disappear into black space in several seconds on the screen like smoke. Typography from this invented instrument is evocative and wistful, and allows the user to associate with ephemeral time. While typing the characters as though playing an instrument at intervals of time, the user can freeze the motion and print out or save otherwise fleeting moment with a button. I intend to contain both characteristics: the amorphous shape of smoke and the elusive attribute of smoke for the expression of intangible and ephemeral time. Every alphabetic shape is derived from the video dips that I shot of smoke. The resulting alphabetic images are then programmed using the Processing scripting language and which can then be typed on the screen with a keyboard. TYME could be a model as a project that reflects the unfixed quality of digital typography, and as a design approach for interactive expressive typography by scripting code. This project also represents the characteristics of typographic play, which can be realized in an computational environment like this model.

A new strut-tie model using secant stiffness, Direct Inelastic Strut-Tie Model, was developed. Since basically the proposed design method uses linear analysis, it is convenient and stable in numerical analysis. At the same time, the proposed design method can accurately estimate the inelastic strength and ductility demands of struts and ties because it can analyzes the inelastic behavior of structure using iterative calculations for secant stiffness. In the present study, the procedure of the proposed design method was established, and a computer program incorporating the proposed method was developed. Design examples using the proposed method were presented, and its advantages were highlighted by the comparison with the traditional strut-tie model. The Direct Inelastic Strut-Tie Model, as an integrated analysis/design method, can directly address the design strategy intended by the engineer to prevent development of macro-cracks and brittle failure of struts. Since the proposed model can analyze the inelastic deformation, indeterminate strut-tie model can be used. Also, since the proposed model controls the local deformations of struts and ties, it can be used as a performance-based design method for various design criteria.
