In The White Card (2019), Claudia Rankine dramatically interrogates whiteness's persistent, reflexive habit of trying to preserve a state of innocence, expressing her vision of how this tendency blinds white liberal subjectivity to the structural reality of institutionalized racism in America. Rankine's exposure of the invisibility to which people of color are usually consigned by American whiteness is inseparable from her critical interrogation of how the hypervisibility of victims of racial violence provides white liberal subjectivity opportunities to intervene and feel good about itself. What Rankine enacts in the play is a process of repetition and revision, signifyin(g) on racial violence and its history; acts of racial violence continue to accrete, and her act of signifyin(g) on the countless acts of racial violence in America conveys the understanding that this text cannot be rewritten if white America continues to attend solely to individual, ostensibly isolated, acts of racial injustice.

The present study investigated characteristics of Korean hourehelds in the expanding stage of the family life cycle depending on decision-making of current and planned credit card use. Households which were selected for this study had at least one dependent child enrolled in primary, middle, or high school, 1998. Regarding current and planned credit card use, credit card holder (n=379) and non-holder (n=259) households and continuous (n=331) and discontinous (n=47) credit card holder households were compared. Comparisons were perfomed by t-test, one-way ANOVA, and X2-test. Related factors were households demographic characteristics, financial management behavior, perceived financial well-being, and attitudes toward credit cards. Findings indicated that holder households tended to be younger, better educated, white-collar workers, and of a higher economic status than non-holders. In comparison to non-holder households, credit card holder households had more favorable atti udes toward credit cards, reported more financial management practices, experienced less financial unbalance, and were more satisfied with their household finaces. Compared to discontinuous credit card holder households, continuous card holder households tended to be larger, have better educated wives and husbands, and have husbands who were white-collar workers. They were more likely to have higher average monthly income than discontinuous holder households. Continuous card holder households also had more favorable attitudes toward credit cards, and more strongly believed and expected financial improvement of their households, compared to discontinuous card holder households.

This paper presents a new security verification technique based on an image encryption by a white noise image that serves as an encryption key. In the proposed method that resembles holographic process, the encryption process is executed digitally using FFT routine which gives chances for separating corruptive noise from reconstructed primary image The encoded image thus obtained is regarded as an nterference pattern caused by two lightwaves transmitted through the primary image and the white noise image. The decoding process is executed optically and in real-tiem fashion where lightwave transmitted through the white noise image illuminates the encrypted card.

This study was conducted to investigate the prevalence of dog erythrocyte antigen (DEA) 1 with DEA 1.1 and DEA 1.2 on 122 Jindo dogs (29 males, 93 females) from 2014 to 2015 using a monoclonal antibody card kit (blood typing card kit, Korea Animal Blood Bank Inc., South Korea). Among the tested dogs, 14.8% (18/122) were positive for the DEA 1.1 antigen and 85.2% (104/122) were positive for the DEA 1.2 antigen. The prevalence of positive types for the DEA 1.2 antigen was significantly higher than the DEA 1.1 antigen (P<0.01). The prevalence of positive types for the DEA 1.1 antigen was higher in white-haired Jindo dogs than yellow-haired dogs (P<0.05). However, there was no gender difference in the prevalence of the DEA 1.1 antigen (P=0.665). The incidence of sensitization after the first transfusion without blood group test was 12.6% and the incidence of acute hemolytic transfusion reaction after the second transfusion in the same immunized dogs was 1.6%. Therefore, the blood group test for the DEA 1 antigen should be performed for Jindo dogs to ensure safe and effective transfusion therapy and further studies remain to be conducted for other DEAs among Jindo dogs.

Most people are using a Color-CCD-Camera in other to acquire a color image. But we are getting a color image with the Monochrome-CCD-Camera equipped for Rotation-Color-Filter in front of the camera lens. The Monochrome CCD Camera has some advantages such as the low price. In addition Rotation-Color-Filter's design is very simple. So we can make this structure easily and economically. In this paper, we described how to make a color image from Monocrome-Camera and correcting color well.

인맥이란 정계, 재계, 학계 따위에서 형성된 사람들의 유대 관계를 뜻한다. 인맥은 거미줄과 같이 서로 뒤엉켜 있고 여러 요인들이 작용하기 때문에 효율적인 인맥 관리를 하기 위해선 많은 시간과 노력이 필요하다. 스마트폰 명함관리 어플리케이션은 모바일 카메라를 이용하여 명함정보를 디지털화 하여 이용하고 있지만 모바일에 정리된 명함의 정보들을 시각화하는 기술은 미흡하다. 따라서 본 논문에서는 명함의 요인들 중 이름, 직급, 회사명, 회사주소, 전화번호, 이메일 주소의 데이터를 이용하여 데이터 시각화 요소를 설계하고 사회연결망 이론을 적용하여 소시오그램 형태로 나타내어 효율적인 인맥 관리가 이루어 질 수 있는 명함관리 시스템 시각화 모형을 설계하였다.

The 13 genre paintings by Junkeun Kim in the book "Korean Games(by Stewart Culin 1858~1929)" were used to study the late $19^{th}$ century's basic costumes and Games style in Korea. The people who appear in the paintings are 26 adult males, 2 minor males, 2 adult females and 3 kisaengs. Typical men wore 'Jeogori' which had various colors and white linings with a reached hip line, and knotted with a 'go-rum' on the right side. They also wore, white colored 'Baji' with colorful sash that were knot below knee or ankle together with 'Hang-jun' or 'Daenim'. They wore 'Beoseon'. Some men wore 'Po' whose colors were blue, green, indigo, white. The general women wore 'Jeogori' in deep green and light pink, indigo, green, red, and they matched with colors for 'Kit' and, 'Go-rum', 'Kut-dong' and its 'Go-rum' was short and narrow. It was so fit and short with narrow sleeve. It had 'Dunggun-kit'(round head collar) with white 'Dong-jung' and so it fit at neck. They wore 'Chi-ma' whose color was red, light green, or light indigo. It contrasted with 'Jeogori'. The width of 'Chi-ma' was big enough. Then white inner slacks came out under the skirt. Traditional Korean games can be classified according to age and gender. Then the games can be further classified into three categories : men's games, women's games, and games for all. The games for adult are an archery practice, hunting, shovel work with a karae, making a bow, drawing Jongkung-chart, Korean chess, playing paduk, and the Korean card game. A swing is a game for women. Games for both men and women are dice play, and domino game. Games for both adult and minor males are sledge, and tightrope walking. Through genre paintings in the $19^{th}$ century, I reached a conclusion that basic costumes are similar to 'Hanbok' at the present time and the method of wearing them has not changed much. It appears that the originality of traditional costumes has been maintained.

Ground reaction force (GRF) measures are one of the most commonly used in biomechanical study. GRF system is very useful educational tool to explain and demonstrate the Newton's law of universal gravitation and laws of motion as well. However, accuracy, intra- and inter- force platform measures' consistency, reliability, noise, and the effect of platform mounting to GRF measures were not clearly viewed. The aim of this study was to examine the above. GRFs of a plastic dummy and two subjects' quiet upright standing were collected at four university laboratories eight force platforms. The types of platforms, analysis programs, and platform set-up were various. Three 100s-trials were conducted with sampling frequency of 100 Hz. First two trials' vertical component of GRFs, Fz, and CoP sway ranges of mid-60s-portion of 100s trials were analyzed by the paired t-tests and one-way ANOVA. Six of eight platforms' 1st and 2nd trial dummy Fz were statistically different (p<.05) and all platforms ICC were poor (<.28). Fz of the two platforms in every four laboratories were statistically different (p<.05). There were white noises and/or very distinctive noises at specific frequency ranges in all Fz measures. 5 Hz low-pass filtering made clear the Fz differences. CoP ranges of dummy were less than 0.5 cm and the best was 0.02 cm. This CoP range finding agrees with previous results suggests the importance of force platform mounting and A/D card resolution.
