郭英信,盧仁淑,金鎭國,金炳洙 최신의학사 1969 最新醫學 Vol.12 No.3
Two cases of scurvy presented in infants who had been nourished by artificial feedings with rice-water and dry milk were reported. These cases menifested gum bleeding, painful swelling of both extremities, and palpable painful rosaries on both sides of the anterior chest. Physical examination revealed poorly nourished, chronically ill appearance with pale face, and severe anemic conjunctiva. Roentgenographic examination showed striking rosaries in all costochondral junctions of the chest, and typical scorbutic findings in the extremities, more outstanding in the lower extremities. Clinical observations on these cases of scurvy were briefly discussed with review of the literature. r tit Ascorbic acid 91 T,5E3 't 1R-s, NJ AJ a}t M IIR a -KA 13t

사회비판적 ‘K-콘텐츠’는 세상을 바꿀 수 있는가? : <스카이캐슬>, <기생충>, <오징어 게임> 의 분열하는 기호들
곽영신,류웅재 한국언론학회 2022 한국언론학보 Vol.66 No.6
This study carefully examined the texts of "Sky Castle," "Parasite," and "Squid Game," which garnered positive reviews while expressing critical viewpoints and discourses on inequality, unfairness, and injustice in contemporary Korean society. We looked at how tense, conflicting, or convoluted the resistance symbols of socially critical pop culture contents are as well as how they function as products of the post-capitalist cultural industry. In particular, it was hoped to demonstrate how text's resistance and the dominating need for intertext resulted in mutual contradiction and conflict, leading to "divided symbols" by examining text-related advertisements and intertexts such as products, events, and media platforms together. Specifically, in the case of <Sky Castle>, the text harshly criticizes inhuman competition and unfairness in Korean education system, but the inter-texts such as advertisements and PPL, products show rather yielding to the current absurd educational system and ironically promoting it. <Parasite> realistically reproduced the harsh daily lives of the lower classes and expressed a sense of problem with the class gap through the hierarchy of space, but once again it dramatically visualized the profound class gap and inequality of capitalism with the award of the US Academy Awards accompanied by conglomerates, sponsored the film. <Squid Game> also allegorically reveals the murderous competition of the ‘winner-takes-all’ system and the deceitfulness of neoliberal freedom and fairness. At the same time, on the Netflix media platform, the governing ideology is reproduced in a self-reproducing manner through cheers for the top ranking and the ambivalence of autonomy and closure in recommendation algorithms. As a result, texts that address numerous social problems and structural concerns and feature discourses of resistance could be considered to be the main form of socially critical popular cultural contents (signifier). However, at the secondary stage of signification, this text (the sign) is incorporated into the intertext as a new signifier, is entangled with other intertexts that have been subsumed or given up to the demands of the capitalist culture industry and the dominant ideology present in that context, and is ultimately divided. The analysis shows a glimpse of capitalism's evolving mythos and recuperation technique from the polarizing nature of this socially critical popular culture, which can also result in discursive differences in contemporary Korean society. Therefore, it's necessary to develop more sophisticated, creative critical thinking, insight, and imagination so that we can produce pop culture more independently and purge it of concealed ideologies.

Quantifying Visual Specular Gloss Scale
곽영신,박현진,임기형 한국색채학회 2011 한국색채학회 논문집 Vol.25 No.3
Current state-of-art color-difference equations for color quality control are developed mainly for matte surfaces without any gloss or textures. However, most of the home appliances or electrical devices available today have glossy appearance limiting the accuracy of surface color difference prediction. Therefore new visual appearance model development will be the next goal for the color scientists including not only the color but also other surface appearances such as gloss or texture. In this study, as a first step of surface appearance model development, the relationship between the perceived gloss and the measured gloss were investigated. Two sets glossiness data were obtained for the polycarbonate (PC) surfaces with the different levels of UV clear coating. The frist set came from the eleven black and white samples with different gloss levels and the second data set was collected using twenty one black and white samples. The samples were shown in the viewing booth illuminated with D65 simulator and the observers were asked to scale the perceived glossiness between 0 and 100 for black and white samples. Around ten observers participated each experiment. The experimental results showed that the observers can judge a glossiness of a sample consistently regardless the gloss level of the neighboring samples displayed together. It suggests that glossiness is an intrinsic and absolute visual attribute people use to judge the surface appearance. Also it is confirmed that black samples look glossier than white samples having the same physical gloss value. The experimental data in this study could be used to develop mathematical glossiness prediction model.

UHD 영상은 기존 HD 영상 신호보다 훨씬 다양한 색을 표현할 수 있다는 장점이 있다. 넓은 색역을 효율적으로 사용할 수 있게 하기 위해서는 UHD 영상 시스템을 위한 고실감 색표현 기술 개발이 필요하다. 본 고에서는 우선 사람이 보는 색을 표현하는 표준인 CIE 색표계 (CIE Colorimetry)에 대해 소개하고, CIE 색표계를 이용하여 기존 방송 표준 신호 색표현 방법의 문제를 분석한 후, 이를 바탕으로 UHD 신호를 위한 고실감 색표현 기술 개발 방향을 제안하고자 한다.
