In this part the writing group will cover strategies, techniques, and endpoints of atrial fibrillation (AF) ablation. Prior to all, electrical isolation of the pulmonary veins is recommended during all AF ablation procedures. In addition, techniques to be used for ablation of persistent and long-standing persistent AF, adjunctive ablation strategies, nonablative strategies to improve outcomes of AF ablation, and endpoints for ablation of paroxysmal, persistent, and long-standing persistent AF will be reviewed. Currently many technologies and tools are employed for AF ablation procedures. Radiofrequency energy, cryoablation, and other energy sources and tools are in various stages of development and/or clinical investigation. Finally, anticoagulation strategies pre-, during, and postcatheter ablation of AF and technical aspects of ablation to maximize safety are discussed in this section.

This study investigates the effect of Alpha-numeric brand name on the product suitability, brand personality, and attitude. To do that we have chosen the functional sportswear, knowing the fact that the Alpha-numeric brand names are not hard to find in this industry. The changes have been made to Alpha-numeric names, such as the usage/non-usage of number, the size of number being used, the writing method, and the different typeface to suit for the study purpose. The results indicate that the Alpha-numeric brand names do have the effect on increasing the fitness for the product's brand. The bigger number and the cursive script will improve the product's suitability. The customers form positive attitude and favorability on the Alpha-numeric brand name compared to the regular brand name in this industry. The contribution of the study is to dig out the distinction of the communicational effects on the customers when the Alpha-numeric brand names take on the different forms. Therefore the current study enlights the practical value of Alpha-numeric brand name as part of the branding strategy.

The purpose of this paper is to compare the two different instruction methods for Korean learners of academic purposes in learning request expression. Participants were divided into two groups, explicit and implicit group. Both groups viewed several scenes from the drama that involved native speakers interacting in different situations. The instructional treatment for the explicit group included metapragmatic information while the treatment for the implicit group did not. On the other hand, the treatment for the implicit group followed implicit techniques, which were repetition of the video presentation and a script reading activity. This study was made up of a pre-test, a post-test, and a delayed-test. The pre-test was conducted prior to the instructional treatment. The post-test was administered a day after the last instruction and the delayed-test was conducted five weeks after the treatments. Two types of tests, speaking and writing, were used in this study to examine subjects' knowledge of Korean request. The result of this research reveals that implicit treatment was more effective than explicit treatment in Korean learners' request acquisition. This results might have been due to the operationalization of the implicit condition in this study. Implicit instruction may help language learners make rules by themselves through tasks.

플래시 메모리는 오늘날 다양한 형태로 우리 생활의 일부를 차지하고 있다. 이동식 저장매체, 유비쿼터스 컴퓨팅 환경과 휴대전화기, MP3플레이어, 개인정보단말기(PDA) 등의 모바일 제품 등에 광범위하게 사용되고 있다. 이처럼 많은 분야에서 사용되는 주된 이유는 플래시 메모리가 저전력, 비휘발성, 고성능, 물리적 안정성, 휴대성 등의 장점을 갖기 때문이다. 더불어 최근에는 기가바이트급 플래시 메모리도 개발되어 하드디스크의 자리를 대체할 수 있는 상황에 이르렀다. 하지만, 플래시 메모리는 하드디스크와 달리 이미 데이타가 기록된 섹터에 대해 덮어쓰기가 되지 않는다는 특성을 갖고 있다. 데이타를 덮어쓰기 위해서는 해당 섹터가 포함된 블록을 지우고(소거) 쓰기 작업을 수행해야 한다. 이로 인해 플래시 메모리의 데이타 읽기/쓰기/소거에 비용이 하드 디스크와 같이 동일한 것이 아니라 각각 다르다[1][5][6]. 이러한 특성이 고려되지 않은 기존의 OS, DBMS 등과 같은 시스템 소프트웨어에서 사용되는 교체 기법은 플래시 메모리 상에서 비효율성을 가질 수 있다. 그러므로 플래시 메모리상에서는 플래시 메모리의 특성을 고려한 효율적인 버퍼 교체 기법이 필요하다. 본 논문에서는 플래시 메모리의 특성을 고려한 버퍼 페이지 교체기법을 제안하며, 제안된 기법과 기존 기법들과의 성능 평가를 수행한다. 지프분포와 실제 워크로드를 사용한 성능평가는 플래시 메모리의 특성을 고려한 버퍼 페이지 교체 기법의 필요성을 입증한다.

Brands started to manufacture consumer-oriented products and look for active methods to appeal their brands to consumers, in the 1990s. As a result, actively adopting graphic design to clothing designs has recently become an important strategy among others. Graphic design has important significance in contemporary fashion design in the aspect that it has expanded the range of expressive methods by bringing over expressive methods of visual design, and has led to an increase in sales due to consumer satisfaction, but it has been vaguely handled together with textiles design, and research on the topic has been insufficient. Therefore this study aimed to clearly define the idea of graphic design based on documentary research, and analyze applying case and formative features of graphic design expressed in clothing, through case studies from 2004 to 2006, and derive the trends of graphic design expressed in contemporary fashion design. The results of this study are as follows. The common characteristics of images that reflect recent graphic design trends in fashion design are hand writing and irregular composition, and images that actively pursued these pointes were retro and craft images, and modern and sporty images reflected these graphic design trends in a comparatively passive manner. It is important to maintain style differentiation rather than indiscreetly adopting graphic design trends to clothing, and to appropriately apply trend characteristics of fashion design and other design areas. Expressive methods of design are expected to expand through appropriate application and development of graphic design, and can potentially provide a new solution to brand differentiation.

Since the beginning of her dramatic career, Suzan-Lori Parks has considered digging up and restoring African-American history buried under the dominant white Anglo-Saxon history as her mission as a playwright. In Red Letter Plays, she attempts what Deborah Geis called "canon-critique" by taking canonical work by Nathaniel Hawthorne and casting an African-American character as the main character and describing her oppression as an African-American female. This paper argues that Suzan-Lori Parks accuses the oppressive social system by restoring and representing the history of sexual, economic, and racial exploitation that African-American females had to suffer through the dominant image of body and blood. Parks had to rewrite the history of black female characters on their bodies and in the blood because their bodies have been the ultimate object of revulsion and attraction in the perspective of white male. While abhorring and despising Hester La Negrita's abject body, male characters in In the Blood nonetheless not only exploit her sexually and economically but also impregnate her. Hester resorts to her only means of revolting against this oppressive system; she kills her most beloved son and writes "A" on the floor with his blood. Likewise, Hester Smith in Fucking A, who wears "A" on her bosom like Hester Prynne, which in this case means "abortionist," "saves" her son from the hunters by slitting his throat. Abundant graphic and sensational images written on black female body and in the blood are Parks's dramatic strategy to rewrite the forgotten and hidden history of black women's history.

A focusing grating coupler (FGC) was not fabricated by the 'Continuous Path Control'writing strategy but by an electron-beam lithography system of more general exposure mode, which matches not only the address grid with the grating period but also an integer multiple of the address grid resolution (5 nm). To more simplify the fabrication, we are able to reduce a process step without large decrease of pattern quality by excluding a conducting material or layer such as metal (Al, Cr, Au), which are deposited on top or bottom of an e-beam resist to prevent charge build-up during e-beam exposure. A grating pitch period and an aperture feature size of the FGC designed and fabricated by e-beam lithography and reactive ion etching were ranged over 384.3 nm to 448.2 nm, and 0.5 $\times$ 0.5 mm$^2$area, respectively. This fabrication method presented will reduce processing time and improve the grating quality by means of a consideration of the address grid resolution, grating direction, pitch size and shapes when exposing. Here our investigations concentrate on the design and efficient fabrication results of the FGC for coupling from slab waveguide to a spot in free space.

The ODR can be categorized into four distinctive types. First type is the asynchronous non-demeanour method. Second type is the asynchronous demeanour method. Third type is the synchronous demeanour method. Fourth type is the synchronous demeanour method. A typical example of the asynchronous and non-demeanour method is e-mail. The example of the synchronous and non-demeanour method is tele conference. The example of the asynchronous demeanour method is video recordings. The example of synchronous and demeanour method is video conference. The primary benefit of e-mail is to avoid the physical violence. But the costs of email is the lack of emotional aspects of disputants. The benefits of tele conference is ease of use, and reduces the negative aspects of face to face communication. but the costs are limitation of the exchange of written information. The benefits of video conference is the approximation of face to face communication by providing oral as well as visual communication. but it is insufficient to represent eye contact. The common limitations of ODR are as follows. First is the lack of human face. Second is the neutrality of arbitrators and mediators. Third is the authenticity of electronic document. Fourth is the digital divide across South and North and generations. Fifth is the cross-cultural communication. The development strategy of ODR is the training and education of arbitrators and mediators in the area of writing skill. Furthermore, it is necessary to supplement the weakness of email via diverse kinds of expressions to show emotions. Finally, it is necessary to train neutrals in the area of cross-cultural communication.
