Purpose: The purpose of this study was to investigate the associations of obesity and clinical charac-teristics including interleukin-6 (IL-6) with hospital length of stay (LOS) in coronavirus disease-2019 (COVID-19) patients in Korea. Methods: A retrospective descriptive study design was employed to an-alyze medical data from a government-designated hospital in a city of Korea. Clinical data were col-lected from 256 patients with COVID-19 in negative-pressure isolation wards in 2021. The following parameters were analyzed: body mass index (BMI), IL-6 levels, age, sex, comorbidities, healthy habitsat the time ofadmission, and LOS. The statistical package SPSS 26.0 was used for descriptive statistics, the independent t-test, the chi-square test, and partial correlation coefficients. Results: The age of COVID-19 patients was positively correlated with BMI (r = -.16, p = .012), IL-6 levels (r = .14, p = .022) and LOS (r = .26, p < .001). Obesity, non-drinking, hypertension, and older age were associated with longer LOS. Conclusion: These results suggest that age, obesity, and hypertension in COVID-19 pa-tients are related to LOS. Studies investigating other factors that can affect long-term hospitalization in COVID-19 patients are suggested.

텔레비전을 통한 에이즈 정보 습득이 에이즈 및 감염인 관련 지식, 태도, 행동 의도에 미치는 영향

오현정(Hyunjung Oh),전의성(Euisung Jeon),이병관(Byoungkwan Lee) SBS 2016 미디어경제와 문화 Vol.14 No.4

본 연구는 텔레비전을 통한 정보 습득 혹은 정보를 습득한 텔레비전 프로그램 장르(설득/캠페인 vs. 시사/뉴스 vs. 교양/오락)에 따라 에이즈 지식, 감염인에 대한 태도, 감염에 대한 두려움, 낙인 규범 인식, 낙인 행동 의도가 달라지는가를 확인하고, 그 효과가 에이즈 교육에 의해 조절되는가를 분석하였다. 질병관리본부 주관으로 실시한 2015년 ‘대국민 에이즈 행태 조사’에서 수집된 자료를 분석한 결과, 텔레비전을 통한 에이즈 정보 습득에 따른 에이즈 지식과 감염인 태도의 차이가 나타났으며, 감염에 대한 두려움, 낙인 규범 인식, 낙인 행동 의도가 다르게 나타났다. 에이즈 교육은 에이즈 관련 태도 및 행동에 유의미한 영향을 주었으나, 에이즈 지식에는 유의미한 영향을 주지 못했다. 텔레비전 프로그램 장르에 따라서도 부분적으로 유의미한 결과가 나타났는데, 오락/교양 프로그램을 통한 정보 습득이 설득/캠페인이나 시사/뉴스 프로그램을 통한 정보 습득보다 에이즈 관련 부정적 신념이나 낙인 행동 의도를 낮추는 데 더 효과적인 것으로 나타났다. 또한 텔레비전 프로그램 장르가 감염인에 대한 태도에 미치는 영향은 에이즈 교육 경험에 의해 부분적으로 조절되는 것으로 나타났다. The present study explored whether receiving information from different program genres (i.e., news vs. campaign vs. entertainment) influences AIDS knowledge, attitude toward people living with HIV/AIDS (PLWHA), fear of contagion, stigma norm, and intention to stigmatize PLWHA. The study also examined if such influence is moderated by HIV/AIDS education. An analysis of the data collected from 1,000 Korean respondents revealed the following results. First. people who had acquired HIV/AIDS information from television media possessed the greater level of AIDS knowledge and the lower level of AIDS stigma than the respondents who had never acquired HIV/AIDS information through television. Second, receiving HIV/AIDS education significantly lowered people’s AIDS stigma but did not enhance their AIDS knowledge. Third, the genres of television programs had partially significant impacts on people’s AIDS knowledge and stigma; entertainment programs were more effective in reducing AIDS stigma than campaigns or news programs. Fourth, the effects of television programs on AIDS knowledge and AIDS stigma were partly moderated by respondents’ experience of HIV/AIDS education.

본 연구는 잠재프로파일 분석을 이용하여, 청소년의 팬덤 활동 잠재계층을 분류하고, 이에 영향을 미치는 요인 및 학업태도의 차이를 알아보고자 하였다. 연구대상은 한국아동·청소년 패널조사 2018의 1차년도 중학생 조사대상자 중 좋아하는 연예인이나 운동선수가 있다고 응답한 학생 1,547명이다. 연구 결과는 다음과 같다. 첫째, 청소년의 팬덤 활동은 소극적 활동 집단, 온라인 활동 집단, 물품 구매 활동 집단, 서포트 활동 집단으로 분류되었다. 둘째, 각 계층에 대해 성별과 거주지, 친구 관계의 영향을 살펴보았을 때, 성별과 친구 관계가 유의하였다. 셋째, 잠재계층에 대한 결과변수로서 학업태도를 학업 열의(헌신, 활기, 효능감, 몰두)와 학업 무기력(통제신념 결여, 학습동기 결여, 긍정정서 결여, 능동수행 결여)으로 나누어 살펴보았을 때, 활기, 학습동기 결여, 긍정정서 결여에서 유의한 계층 간 차이가 있었다. 본 연구는 청소년의 팬덤 활동에 대한 응답을 통해 잠재계층을 구분하여, 팬덤 활동 유형에 대한 이해를 돕고자 하였으며, 유형을 구분하지 않거나 자의적으로 구분한 기존 연구의 한계를 극복하고, 팬덤 활동의 학업태도에 대한 긍정적·부정적 측면을 동시에 알아보았다는 의의가 있다. The purposes of this study are to classify fandom activities of adolescents by latent profile analysis and to identify determinants and consequences of the latent profiles. The subjects of the study are 1,547 middle-school student subjects of the first survey of the 'Korean Children and Youth Panel Survey 2018' who responded to questions about whether they have favorite entertainers or athletes. Results are as follows. First, youth's fandom activities were classified into four groups: 'passive activity group', 'online activity group', 'product purchase activity group', and 'support activity group'. Second, when examining the effects of gender, residence, and friend relationship, gender and friend relationship were significant in determining the latent profiles. Third, among the academic attitude variables as outcome variables, lack of vitality, learning motivation, and affirmation showed significant differences across the latent profiles. This study made contributions to identifying the types of fandom activities of adolescents by dividing latent profiles and thus overcoming the limitations of existing studies that did not distinguish types of fandom activities or classified them arbitrarily.

일본어의 형용사의 어순에 관한 연구

오현정(Oh HyunJung) 한국외국어교육학회 2005 Foreign languages education Vol.12 No.2

This study investigates the tendency of the word order of Japanese adjectives. Japanese adjectives are the representative adjectival modifiers and they define the nature, condition and characteristics of the words that are defined. There were not many studies on the word order among Japanese adjectives; however, their natural and general word order exists in case that the plural adjectives are used in the sentence. This study reveals the existence of a tendency in word order such as the adjectives representing the amount, the adjectives representing the old and new and the short- and long-term period and the adjectives representing the evaluation (judgment) by means of focusing on the word order among Japanese adjectives. Meanwhile, the adjectives representing the small and large, color and shape are not likely to have their word order. In short, this study suggests the following word order: amount〉time (old and new, long-term and short-term)〉small and large, color, shape〉evaluation> main noun.

(Background and Purpose) Richard Meier is the most important person among modern and contemporary architects who represents U.S.A. He accurately expressed white architecture, his own architectural form through the relational context of neighboring areas. His white architecture symbolizes the purity of origin. His expression of simple architectural space as the archetype pursues an absolute value in external and internal space. Richard Meier describes the void and fill of space and physical properties of water and light with esthetic and poetic expressions. Along with them, many philosophers and thinkers gave birth to structuralism, a philosophical idea. The dichotomy of relations and the entity of philosophical thought, such as the inside and the outside of a space, subjective idea and structural system, and human consciousness and unconsciousness were divided through phenomenological or interpretive thoughts or sometimes constituted an interrelated systematic frame through the philosophical concept of structuralism. This study aims to analyze contextual factors in depth, composing the system of architectural space, through Richard Meier's white architecture and the methodology and thoughts of structuralism, from the perspective of the philosophical concept of structuralism. (Method) This study initially analyzes the context of architecture with the methodology of structuralism, by summarizing synchronicity and diachronicity, the categorical characteristics of structural linguistics, paradigmatic and syntagmatic relationship, and the concept of metaphor and metonymy. First, it attempts to divide the thought of structuralistic philosophy into tangible and intangible spatial factors in the semiotic context, examine conscious contents and unconscious expression relationship in the context of psychological forms and investigate the logical characteristics of origin and change, in the context of relational substitution. Second, it aims to analyze the characteristics of architectural space based on key words of structuralistic architectural context by using 9 works representing for Richard Meier's white architecture around living, commercial and educational spaces: semiotic, innateness, regularity. transposition, metonymy, confrontation, intellectualism, geometry and rationality. (Results) This study thus analyzed neighboring local environment and historical temporal context as well as spatial system's characteristics appearing in Richard Meier's white architecture, based on the philosophical through of structuralism and the spatial relationship in the context of innate semiotic structures, metonymical transposition structure and geometrical intellectual structure. (Conclusions) There are philosophical characteristics of structure in the semiotic, psychological and relationship system of Richard Meier's white architecture, and metaphor and metonymy of close relationship among synchronic, diachronic, and paradigmatic and syntagmatic spaces are used. In addition, the linkage into the whole and sub-spaces for architectural arrangement has an intellectual system and is logical and reasonable. Richard Meier produced mathematic rules by using geometric factors and expressed users' spatial experiences through the transference of various visual-perceptual sense organs.
