Purpose: The aim of this study was to investigate the use and acceptance of digital radiographic examinations by Brazilian dental practitioners in daily practice and to evaluate the advances that have occurred over the past 5 years. Materials and Methods: Dental practitioners enrolled in extension courses at the Piracicaba Dental School, University of Campinas, Brazil, responded to a self-administered questionnaire in the years 2011 and 2015. They were asked about sociodemographic factors and their knowledge and use of digital radiographic examinations. Descriptive analysis was performed, as well as the chi-square and Fisher exact tests, with a significance level of 5% (α=0.05). Results: A total of 181 participants responded to the questionnaire in the years 2011 and 2015. Most of the respondents worked in private practice, had graduated within the last 5 years, and were between 20 and 30 years old. In 2011, 55.6% of respondents reported having ever used digital radiographic examinations, while in 2015 this number increased significantly to 85.4% (p<.0001), out of which 71.4% preferred it to conventional images. Moreover, 21.4% of respondents reported having used digital radiographic examinations for more than 3 years. A significant increase in use of intraoral digital radiography (p=0.0316) was observed in 2015. In both years, image quality and high cost were indicated, respectively, as the main advantage and disadvantage of digital radiographic examinations. Conclusion: This study showed that digital radiology has become more common in Brazil over the past 5 years. Most of the Brazilian dental practitioners evaluated in 2015 used digital radiographic examinations.

Candidiasis is the most frequent infection by opportunistic fungi such as Candida albicans, Candida tropicalis, and Candida krusei. Ethanol extract from Eugenia uniflora was assayed, for its antifungal activity, either alone or combined with four selected chemotherapeutic antimicrobial agents, including anphotericin B, mebendazole, nistatin, and metronidazole against these strains. The obtained results indicated that the association of the extract of E. uniflora to metronidazole showed a potential antifungal activity against C. tropicalis. However, no synergistic activity against the other strains was observed, as observed when the extract was associated with the other, not enhancing their antifungal activity.

Impact of the International Status of the Interpreting Student`s Mother Tongues on Training

( Karla Dejeanle Feal ) 한국통역번역학회 2003 FORUM Vol.1 No.1

Un des facteurs qui exerce une grande influence sur la formation d`interpretes est le statut dont la langue maternelle des etudiants jouit dans les conferences internationales ainsi que la resistance que cette langue est susceptible d`opposer a la tendance croissante a employer l`anglais comme seul moyen de communication. L`article traite de l`incidence du statut de langue de moindre diffusion sur les exigences qualitatives a l`egard de l`interpretation ainsi que sur les besoins quantitatifs en interpretes de cette langue. Les problemes poses par le “retour” que les interpretes de langues de moindre diffusion sont le plus souvent obliges de pratiquer et l`enseignement de ce retour sont exposes plus en detail.

40 Years of Leisure Research in the United States

Karla A. Henderson 한국여가레크리에이션학회 2009 한국여가레크리에이션학회지 Vol.33 No.1

Leisure research is a relatively new area of inquiry in the US as well as around the world. The first journals in the U.S. focusing primarily on leisure research began less than 40 years ago. Since that time, the research addressing various leisure-related phenomena has grown in quantity and quality. The purpose of this paper is to examine the leisure research published in the U.S. in the Journal of Leisure Research and Leisure Sciences in recent decades. This analysis shows the evolution of theory and methods as researchers have addressed concerns raised. For example, early research focused predominantly on outdoor recreation management while leisure behavior in its broadest form applied to a diversity of populations has become more common today. Further, early research used primarily quantitative methods and statistics but a growing number of recent studies use qualitative approaches to examine leisure behavior. In addition, the past history points to issues and challenges for the future such as including more researchers worldwide in the dialogue, applying the research to improve the lives of people, expanding the methods available, and determining relevant topics that require more exploration.

Karla P. Monroy,Jordi Delgado,Lídia Sereno,Joaquim Ciurana,Nicolas J. Hendrichs 대한금속·재료학회 2014 METALS AND MATERIALS International Vol.20 No.5

Selective Laser Melting (SLM) is an additive technology that produces solid parts by selectively meltingthin layers of metallic powder. SLM can produce significant differences in the final properties due to themelting-consolidation phenomena of the process, which can be controlled by the appropriate parameters. Therefore, the objective of this study was to create a link between the process conditions and the resultingproperties by experimenting in an own-developed SLM machine using CoCrMo powder as material. The fabricated samples were characterized by density, hardness and microstructural properties. The experimentalresults proved the capability of the SLM technique to build high dense samples. The hardnessresults gave evidence of a superior outcome compared to conventional processes. Finally, it was found thatgrain size was defined by scanning speed. Based on the results, a better understanding of the processingprinciples given by the parameters was achieved and improved fabrication quality was promoted.

A new spray-on topical wound debrider composition consisting of 0.1% w/v papain immobilized in 6% w/v pectin gel was formulated for skin wound healing. The stability of the enzyme activity of this new formulated spray was compared with the 0.1% w/v papain in water solution at the refrigerated temperature of 4 and 75°C. Two aerosol propellants, air and nitrogen, were evaluated for their efficacy. The new formulated spray was then evaluated for its thermal stability under air and N2 at 75°C. All enzyme activity of papain was measured with a spectrophotometer using casein as a substrate at 37°C and in 0.1 M phosphate buffer at pH 6, as well as trichloral acetic acid to separate the product of casein hydrolysis. All the evaluations showed the new aerosol spray formulation to be far better than the liquid formulation in storage stability and thermal stability at 75°C under atmospheric or higher pressures. The new formulation was tested in a rabbit experiment to evaluate the effectiveness of wound healing. As compared to untreated wound, the formulated spray clearly was superior, yielding a 20% more healing progress in the first 4 days alone.

Global Entanglements: Reflections on researching religion in a post 9/11 world (Part I)

최근의 많은 연구는 발화 형식들, 그리고 담론 그 자체 안에 권력이 있다는 가정에 근거한 푸코의 담론모델을 통해서 알려진다. 인간의 구체성, 행동, 멘토, 그리고 이것들을 형성하는 제도들 그들을 사로잡는 세계관은 무시된다. 세계적으로 복잡하게 얽혀 있는 관계들과 나치즘의 지속성을 정확하게 이해하기 위해서는 또 다른 접근법이 요청되는데, 왜냐하면 이것이 바로 대부분의 사람들이 잊고 싶어하는 정치적인 종교이기 때문이다. 비유적으로 말하자면, 이 접근법은 마치 양파껍질 벗기기와 같다. 이 논문은 마치 사실이 아닌 것만 같은 한 책에 대한 평가이다. 자신을 종교 연구가라 주장하는 지그리트 헝케(Sigrid Hunke)는 1960년에 출판된 『서구에 비추는 알라의 태양: 우리의 아랍 유산』이라는 이상한 제목의 베스트 셀러를 집필하였다. 헝케에 따르면, 그녀는 서양의 편견에 대항하여 아랍의 이슬람을 옹호하기 위해 책을 썼다고 한다. 그러나 최초의 아카이브 조사를 통해 그녀가 열성적인 [나치의] SS 지식인이며, 1940년대의 전형적인 게르만 옹호자였다는 것이 알려졌다. 그렇다면 왜 2차대전 이후에 정치-종교적 소수자에 동조하는 인권옹호자로 전환한 것이 더욱 본받을 가치가 있는 모델로 제기된 것인가. 여기서 양파껍질 벗기기의 비유가 유용하게 사용된다. 이를테면 속임수를 벗기도록 나를 인도해 주는 방법과 개념에 대한 해석을 담고 있는 텍스트 박스들을 가지고 논문의 흐름을 잘라내고 있기 때문이다. 이를 넘어서서, 더 중요하게는 독자들을 나치 세계관의 핵심으로, 그리고 이것을 구성하는 그들 자신만의 방법과 개념들―헝케는 그녀의 작품 속에서 이 방법과 개념들을 충실히 따랐다―을 고안했던 헝케의 멘토들에게 데려간다.

Promoting an Energy Partnership in Northeast Asia

( Karla S. Fallon ) 인하대학교 국제관계연구소 2006 Pacific Focus Vol.21 No.1

Are we witnessing tentative steps towards an energy partnership or energy community in Northeast Asia? Is such an energy partnership possible? This article traces and analyzes recent dialogue, negotiations, agreements and proposed projects for energy cooperation among Russia, China, Japan, and South Korea. It addresses the implications of China`s growing energy demand and implications of Russia`s attempts to move from a lost position as a political and military superpower to an energy superpower. The article concludes that reports of competition over Russian energy resources among Japan, China, and South Korea are exaggerated and that there is much opportunity for cooperation among these countries. However, a failure to devise and articulate clear and long-term national energy security policies and strategies, particularly by Russia, may lead to the closing of this window of opportunity for cooperation.
