파일 공유를 위해 널리 사용되는 BitTorrent는 대표적인 P2P 프로토콜이다. BitTorrent는 전송을 요구한 클라이언트가 작은 단위로 쪼개진 하나의 파일을 다수의 클라이언트들로부터 받는 방식으로 기존의 일대일 P2P 전송방식에 대비하여 빠른 다운로드 속도를 낼 수 있다. 이러한 다운로드 성능을 발휘하기위해 다수의 조각으로 분리 된 파일 조각을 선택하는 Pieces Selection 기법은 매우 중요하다. 이에 본 논문에서는 BitTorrent에서 활용되는 네 가지의 Pieces Selection 기법에 대해 알아보고, 성능 개선을 위한 새로운 기법을 제안한다.

Loewe Craft Prize is currently the most influential craft contest. During the contest, contemporary craftworks, as art with excellent aesthetic value, are selected as finalists but there are no enough studies on them as subjects. This study aimed to investigate contemporary textile pieces found in the fashion brand Loewe's Craft Prize, a Loewe Foundation Craft Prize and elucidate their expressive characteristics. The methodology of the study was a qualitative study that derives the expressive characteristics of the works within the scope of the study through case analysis along with theoretical reviews. The selection of research subjects was based on 22 works of textile pieces among the works selected as finalists for the last six years since the first year of the prize in 2016. The analysis of textile pieces showed first, the emphasis on traditional expression, second, the development of new expressive techniques for the material, and third, the pictorial character revealed in flat pieces. The expressive characteristics of contemporary textile art shown in the Loewe Foundation Craft Prize, derived based on such results were, first, the confirmation of the unique capabilities of craft through the inheritance of tradition, second, the rediscovery of textile properties through material experimentation, and third, the possibility of expanding the field of textile due to the pictorial character.

In this study, we analyzed the determinants of wages of college graduates by using the data of "2014 Graduates Occupational Mobility Survey" conducted by Korea Employment Information Service. In general, wages contain two complex pieces of information about whether an individual is employed and the size of the wage. However, in many previous researches on wage determinants, sample selection bias tends to be generated by performing linear regression analysis using only information on wage size. We used the Heckman sample selection models for analysis to overcome this problem. The main results are summarized as follows. First, the validity of the Heckman's sample selection model is statistically significant. Male is significantly higher in both job probability and wage than female. As age increases and parents' income increases, both the probability of employment and the size of wages are higher. Finally, as the university satisfaction increases and the number of certifications acquired increased, both the probability of employment and the wage tends to increase.

This study aims at developing and producing the creative design of a lingerie look after reviewing the aesthetic value about lingerie look featured in John Galliano's works. As for the research method, the selection process from the works was followed together with literature review for empirical analysis over lingerie looks, where 2,764 pieces in total were reviewed from Galliano's Pret-a-Porter collections covering from 2001S/S until 2010F/W and Christian Dior's Haute Couture and Pret-a-Porter collections that he is in charge of as head designer and 291 pieces were finally singled out that show the lingerie look image well. Then, the formative expression was examined about those looks and the characteristics were induced from them. Formativeness expressed in Galliano's lingerie look, in term of lingerie style, was categorized as erotic, retro, and deconstructive. The glittering and smooth material like silk and satin, and the visible material like lace and chiffon were mainly used for material rather than foreign material. By doing so, the romantic and erotic image was highlighted. In the production method, it was grouped into transposition of wear, direct and indirect exposition, and deconstructive way. These aesthetic characteristics introduced by formative expression appeared in the form of eroticism, play, and deconstructiveness.

This research analyzes students' response types in the creativity assessment by using pattern block, geoboard, and pantomino. 74 students from third grade to sixth grade participated in this research. 15 minutes were given to pattern block and geoboard questions. 74 students showed 393 answers in pattern block question and 590 answers in geoboard question. In pantomino, 20 minutes were given and 54 students showed 443 types of answers. The results are as follows: First, in the students' responses, tendency of using particular piece or figure, which presents conjoining in a piece selection and positioning, showed strongly. For example, usage of hexagon and trapezoid pieces were higer in pattern block and usage of L, P, and I pieces were higer in pentomino. Second, it is confirmed that creativity's subordinate factors, fluency, flexibility, and originality, are separate from each other. To illustrate, in pattern block, three students', who showed 11 types of responses in fluency, flexibility responses were each 5, 6, and 8 types. Specially, among those studenys, only one could achieve a point in originality. Third, students' response types categorized in this research could be used for a bae-data to mark grades on originality.

The purpose of this study was to present the necessary data concerning the selection and development of floor-coverings in view of slipperiness by comparing the relationship between CSR measured with O-Y·PSM and RCOF calculated from the result of gait analysis. CSR was calculated from maximum tensile load(Pmax) divided by perpendicular load(785N) when pulled 18 degrees upward the moment the bottom of the slip piece contacted the surface of the test piece. RCOF was calculated based on Fy/Fz from when horizontal load reached the maximum point within the sections from the moment the front of outsole touched the test piece to when pulled off the test piece. The results from the research were as follows: (1) Range of CSR was 0.15-1.02, which meant the differences of slipperiness of the test pieces definitely showed up. (2) RCOF are inadequate to express the characteristic about the slipperiness of the floors, since there were no differences between the test pieces.

The purpose of this study is to delve into the identity of the New-Hanbok style in modern fashion, and to survey its formative characteristics and internal values from the perspective of vernacular design. Arguments can be summed up as follows. The study historically examines the changes in Hanbok and concludes that the social and cultural backgrounds and factors that caused the advent of the New Hanbok are (1) the change and expansion of the basic social, cultural, and popular perception toward the Korean image, (2) the rapid spread of a subculture centering on the younger generation, and (3) the voluntary and systematic activities of nonprofit clubs, communities and private organizations. This is the cycle of the spread of Hanbok, which shows the subcultural selection and development process of upward propagation. Furthermore, the public, in addition to holding fast to an independent attitude regarding their choices, also show that they tolerate diversity. As a perspective of analyzing the New Hanbok style, the study suggests the characteristics of the vernacular design perspective as (1) a spontaneous indigenous nature (2) living everydayness (3) and the subcultural-ness of the era. From such a perspective, the study examines the formative characteristics of the basic costume configuration of the New Hanbok style including jeogori, traditional Korean skirts, Cheollik one-pieces, and Trompe l'oeil one-pieces, and draws out the meanings contained in the New Hanbok style, which are (1) spontaneous indigenous nature and directivity toward tradition, (2) living everydayness and modernity, and (3) open subcultural-ness.
