사이트 고장율의 변화에 대한 2 Phase Commitment 프로토콜의 성능

이윤숙(Yun Sook Lee),문송천(Song Chun Moon) 한국정보과학회 1987 한국정보과학회 학술발표논문집 Vol.14 No.1

분산 데이타베이스 시스템에서 트랜잭션을 수행시킬 때 참여자와 조정자가 같은 결과가 나오도록 하는 것은 쉬운 일이 아니다. Two-Phase Commit 프로토콜(2PC)은 트랜잭션의 atomicity를 이루기 위하여 제안된 것이다. 2PC 프로토콜은 트랜잭션의 결과를 조정자와 참여자간에 같은 결론에 이르도록 하지만 사이트가 고장이 나면 참여자와 block되는 단점이 있다. block되면 그만큼 시스템의 활용도는 떨어지게 되고 효율성이 낮아진다. 본 논문에서는 사이트의 고장율의 변화에 따라 트랜잭션의 수행시간과 트랜잭션당 메세지의 교환 횟수가 어떻게 달라지는지 시뮬레이션을 통해 연구하였다. 사이트의 고장율이 높아지면 트랜잭션의 수행시간과 메세지의 교환 횟수는 높아진다. 그러나 트랜잭션의 수행 시간은 사이트의 고장율이 어느정도 이상으로 높아지면 오히려 떨어진다.

본 연구에서는 가정에서의 유아 문학경험이 어떤 것인지에 대한 전반적인 실태조사를 하고, 특히 책읽기와 관련한 부모인식이 어떠하며 책읽어줄 때 방법 및 상호작용이 어떻게 이루어지고 있는지, 인구통계학적 변인에 따라 차이가 있는지에 대해 조사하였다. 조사대상은 천안 시에 소재한 유치원과 어린이집에 자녀를 보내는 어머니 437명이었다. 수집된 자료의 분석은 SPSS 통계 Program을 사용하여 빈도분석 및 일원변량분석과 Duncan검증을 실시하였다. 연구 결과, 첫째, 유아들이 가정에서 가장 많이 접하는 문학경험 형태는 그림책이었다. 그림책은 주로 부모와 함께 보았으며, 유아들이 가정에서 가장 즐겨 읽는 책은‘전래동화’였고 주로 200권 이하의 그림책을 보유하는 가정이 가장 많았고 일주일에 3-4회, 20-30분씩 시간을 정해서 읽어주고 있었다. 둘째, 책 읽어주기 실태에 따른 결과에서는 가정에서 책읽어주기와 관련한 부모인식, 책읽어주기 방법, 상호작용 점수가 대체로 높았으며, 책읽어주기 중요성에 대한 부모인식은 모 직업, 월 소득, 부모학력에 따라, 가정에서의 책읽어주기 방법은 유아연령과 월 소득에 따라 차이가 있었지만 책 읽어줄 때의 상호작용에서는 인구통계학적 변인에 따라 차이가 없었다. The purpose of this study is to investigate overall situation concerning whether what literature experiences children have at home, and identify how parents' perception of reading books for their children, the methods of parents' reading books for their children, and interaction can be different, depending on the variables of family background. Through the study results, this study pursues to provide the implications of effective home literature environment by identifying to what literature environment children are exposed at home. This study targeted 437 parents who sent their children to four kindergartens and six daycare centers located in Cheonan City. A questionnaire survey was carried out using a tool that the author of this paper reproduced, based on the studies of Weigel, Martin& Bennett (2006), Ah Jeong Gwak (1994), and Sook Yee Kim (2004). The collected data were statistically processed using the SPSS 12.0 program. The results of this study can be summarized below: First, Though children encounter various literature types, such as video/DVD/CD fairly tales, and those on the Internet, TV, and cassette tape recorder, the most popular literature experience was through picture books. Even though the children read the picture books mainly with their parents, children watched fairly tales on the Internet, video/DVD, and TV alone in more cases. The books that the children most enjoy were traditional fairly tales, and the genre that parents usually read for their children was creative fairly tale. The largest number of homes owned 11-12 video/DVD/CD books as children's literature materials, and the children watched once or twice a week with a duration of 20-30 minutes per session. Mainly mothers read the picture books for their children regularly three or four sessions a week with a duration of 20-30 minutes per session. When the parents buy picture books, they visit a book store with their children. Second, parent recognized the importance of reading books for their children at home, and there were differences depending on mother's occupation, monthly income and parent's education levels. The methods to read books for children at home appears that is reading to children to consider children's interesting and development, there are differences depending on young children's age and monthly income. When parents read books to children, interaction between parents and children were more sufficient than mediocre, and there were no any differences depending on the variables of statistics of population.

This paper is to present a teaching model to improve middle school students' English proficiency by organizing special ability groups after school, as specified in the 7th national English curriculum. It is understood that the current grade system by ages and teaching students at the same grade level in the same way cannot meet their various needs. A review of the relevant literature describes the background information concerning the adoption of the new national English curriculum and reports some experimental case studies which investigate the effect of English teaching in ability groups of some kind. The main part of this paper deals with specific procedures followed in and important findings of an English teaching experiment. The result of this study reveals that English teaching in small ability groups has a great potential with more systematic grouping procedures taken, with various teaching materials used and with better classroom environment maintained.

The pupose of this study was to examine the comfort properties of functional fabrics, such as aluminium coasted thermal fabrics, water repellent, quick drying, antistat, silk like, and wool like finished fabics. Generally, thermal resistances and water vapour and liquid water transports properties in terms of the comfort aspects were not satisfactory for functional finished fabrics.

Korean apparel industry is facing critical moment due to shortage of labor, wage increases and intensive competition among domestic manufacturers. In addition, international production has been shifting to China and the other low wage countries from established locations such as Korea, Hong Kong and Taiwan. Global sourcing has been received considerable attention since firms can enhance their competitive advantage as well as comparative advantage by coordinating their sourcing activities globally. This study regarded global sourcing as one of the strategic tools to achieve competitive advantage of Korean apparel firms, and explored the current status by literature reviews and series of in-depth interviews with managers of Korean apparel firms. The findings of this study were as follows: 1) Due to geographical advantage, China was the most favored nation for outsourcing for domestic markets. However, exporting firms preferred Latin America (including Mexico) to take advantage of duties, quotas and geographical proximity to the US market. 2) In selecting the global sourcing country, productivity, technical ability, local government regulation, and culture were considered important. 3) Most Korean apparel firms sourced production globally, and followed by raw materials and trims. 4) Cost and quality were the most important factors in deciding subcontractors, and experience, productivity, equipment and finances were the next concerns. Academic implications and future directions were suggested based on findings.

The purpose of this study was to investigate the fashion trends of last three years and how the trends were imaged by the structural characteristics of the fabrics. The characteristics for 897 fabrics were analyzed from four kinds, eleven volumes of fashion trend magazines. From these magazines, three panels categorized by their frequencies as nine images such as natural, innocent, romantic, ethnic, childish, casual, classic, modem and technical. Sub-images of each image such as rustic, irregular, decorative, etc were also categorized. For the each image, fiber contents and structural characteristics of weave type, weight, density, yarn size, twist and fabric finishes were investigated in terms of frequency, range and mean. Results showed that chiffon and organza seemed to have very specific images and used to represent specifically the romantic or ethnic images; whereas voile and jersey was used to represent various images. For S/S seasons, most popular fiber type was cotton. The weave type was not the important factor to give variations in images; plain weave and the jersey were exclusively used irrespective of images. For the romantic, ethnic and innocent images, rather light fabrics were used. For the childish and natural, medium weights, and for the technical, modern and classic images heavy weight fabrics were used. Various finishes were employed to represent specific images.
