The purpose of this study was to examine the influence of pre-service special education teachers’ demographic variables and multicultural experiences upon their perception and efficacy on multicultural education. A sample of 481 pre-service special education teachers in the college of special education was included in the study. The questionnaire items consisted of 50 items with subscales for demographic trend(9 items), experience(7 items), perception(14 items), efficacy(20 items). Results showed that the general levels of multicultural perception and efficacy among the subjects were average. However, the general levels of multicultural experience were low. The study findings indicated that the pre-service special education teachers’ efficacy were different according the grade, income level, and courses on multiculture. However, there were no differences among the groups according to sex, religious background, place of growth in multicultural experience, perception and efficacy. Higher multicultural experience were associated with positive perception and efficacy on multicultural education. 본 연구의 목적은 예비특수교사들의 배경변인에 따라 다문화 경험, 다문화 인식 및 다문화 효능감에 어떠한 차이가 있는지, 그리고 예비특수교사들의 다문화 경험이 다문화 인식과 다문화 효능감에 어떠한 영향을 미치는지를 알아보는 것이다. 이를 위해 광주·전남, 부산·경남, 대전·충청 소재의 9개 대학교의 특수교육과 학생들(N=481)을 대상으로 설문조사를 실시하였다. 예비특수교사들을 대상으로 한 설문지는 응답자의 배경 정보와 관련된 문항들과 함께 다문화 경험, 다문화 인식, 다문화 효능감으로 구성되었다. 연구결과, 배경변인 중 학년, 가정의 사회·경제적 수준에 따라 다문화 효능감에서 차이를 보였고, 다문화 관련 강좌 수강 경험 유무에 따라 다문화 인식과 다문화 효능감에 집단 간 차이를 보였다. 예비특수교사들의 성별, 종교, 출생 후 성장도시와 같은 배경변인들은 예비특수교사들의 다문화 경험, 다문화 인식, 다문화 효능감에 영향을 미치지 않는 것으로 나타났다. 이와 함께 예비특수교사들의 다문화 경험 수준에 따라 다문화 인식과 다문화 효능감에 차이를 보였으며, 예비특수교사들의 다문화 경험은 다문화 인식의 10%, 다문화 효능감의 2%를 설명하였다.

미디어교육이 청소년의 TV광고판별능력에 미치는 영향

권성호,류미아 한국교육정보방송학회 2001 교육정보미디어연구 Vol.7 No.3

청소년에게 미치는 미디어의 영향력은 매우 크다. 어릴 때부터 컴퓨터, TV, 비디오 등의 영상을 통해 정보를 획득하는데 익숙해져 있고 감각이 발달된 세대이기 때문이다. 특히 청소년의 소비유형은 즉흥적이고 감정적이며 자기중심적이면서 외형에 신경을 쓰고 모방성이 강하기 때문에, 구매동기나 구매행동은 TV광고의 영향을 많이 받는다. 청소년들이 특히 TV광고의 영향을 많이 받는 것은 TV광고의 허구와 기만을 제대로 읽지 못하는 것이 한 원인이 될 수 있다. 본 연구에서는 우리나라 미디어 교육의 연구동향과 이미 실시되었던 미디어광고 교육프로그램을 분석하여 이를 토대로 청소년을 대상으로 하는 'TV광고에 대한 미디어교육프로그램'을 개발하였다. 그리고 이를 적용한 후에 미디어 교육이 청소년의 TV광고판별능력에 미치는 영향을 알아보았다. 미디어교육을 받은 집단은 TV광고의 기만성을 읽어내는 TV광고판별능력이 신장되었다는 본 연구의 결과는 미디어를 분석하고 이해하며 비판적으로 수용할 수 있는 능력을 향상시키는 미디어교육의 중요성을 입증하였다. The purpose of this study is to investigate the effect of media education on adolescent TV advertising discriminatory competency. In order to achieve the purpose of study, the media education program was developed. The developing step was presented based on the 3-stages: establishment of the program goals, the design of education contents and instructional plan, the design of the learning guidance plans and training materials. To examine the effect of the media education about TV advertisement the hypothesis was formulated as follow; The educated group on the media education about TV advertisement would be higher in TV advertising discriminatory competency than uneducated group's. To verify these hypotheses, the subjects of this study were 82 2th grade girl students selected from 2 classes of high school located in Seoul. The subjects were classified into two groups : 41 students of a class participated in the media education about TV advertisement, and 41 students of a class did not participated in the media education about TV advertisement. The pretest was administered by comparing each group member's TV advertising discriminatory competency before the media education about TV advertisement. The finding of this study was that the educated group on the media education about TV advertisement was higher in TV advertising discriminatory competency than uneducated group's. And that is significant in statistic(p<.01). In conclusion, it was found that there was effect of media education about TV advertisement on adolescent TV advertising discriminatory competency. But adolescence accept advertisement through not only TV but magazine & new media for example internet, etc. Therefore, The wider ranging study on the characteristic and effects of more various media is needed.

Analysis of carbon monoxide in postmortem spleen specimens by GC-TCD

Miyeon Lee,Mia Kwon,Hyun Jee Kim 한국분석과학회 2021 학술대회논문집 Vol.2021 No.11

Carbon monoxide(CO) is a gaseous diatomic molecule that has no taste, color or odor. It is generated during incomplete combustion of hydrocarbon-based substances, such as from poorly ventilated fires, wood, gasoline, and exhaust gases from petroleum-fueled engines. CO is known to have the potential to cause serious adverse health effects related to the respiratory, cardio-circulatory and neurological systems, which in the worst case can lead to death. If sufficient femoral venous blood(FVB) can be collected from autopsy, the concentration of carboxyhaemoglobin(COHb) in the blood can be measured using the CO-oximetry method. However, the above method cannot be applied if the blood volume is insufficient or the postmortem is highly putrified. In this case, in order to assess whether or not death is caused by CO, the concentration of COHb in the spleen specimens, which can be a major substitute for blood that provides a rich source of erythrocytes in living tissues, can be analyzed by gas chromatograph-thermal conductivity detector(GC/TCD). In 21 spleen specimens from autopsy, there were cases of COHb poisoning at levels of 58-94% due to charcoal and fires in vehicles and rooms, but levels up to 27% were found in individuals who did not show symptoms of CO poisoning. In most cases of highly purified postmortem, CO was found to be produced in significant quantities in cases that were not related to fire- or CO exposure. COHb levels of 25% in a postmortem case may be considered as a contributing factor to the cause of death but should not be considered exclusively as the cause of death. It is suggested that the CO in a putrified postmortem is due to CO in blood prior to death and the CO formed by the decomposition of Hb, myoglobin, and other substances during putrefaction.

Both α2,3- and α2,6-Linked Sialic Acids on O-Linked Glycoproteins Act as Functional Receptors for Porcine Sapovirus

Kim, Deok-Song,Hosmillo, Myra,Alfajaro, Mia Madel,Kim, Ji-Yun,Park, Jun-Gyu,Son, Kyu-Yeol,Ryu, Eun-Hye,Sorgeloos, Frederic,Kwon, Hyung-Jun,Park, Su-Jin,Lee, Woo Song,Cho, Duck,Kwon, Joseph,Choi, Jong- Public Library of Science 2014 PLoS pathogens Vol.10 No.6

<▼1><P>Sapovirus, a member of the <I>Caliciviridae</I> family, is an important cause of acute gastroenteritis in humans and pigs. Currently, the porcine sapovirus (PSaV) Cowden strain remains the only cultivable member of the <I>Sapovirus</I> genus. While some caliciviruses are known to utilize carbohydrate receptors for entry and infection, a functional receptor for sapovirus is unknown. To characterize the functional receptor of the Cowden strain of PSaV, we undertook a comprehensive series of protein-ligand biochemical assays in mock and PSaV-infected cell culture and/or piglet intestinal tissue sections. PSaV revealed neither hemagglutination activity with red blood cells from any species nor binding activity to synthetic histo-blood group antigens, indicating that PSaV does not use histo-blood group antigens as receptors. Attachment and infection of PSaV were markedly blocked by sialic acid and <I>Vibrio cholerae</I> neuraminidase (NA), suggesting a role for α2,3-linked, α2,6-linked or α2,8-linked sialic acid in virus attachment. However, viral attachment and infection were only partially inhibited by treatment of cells with sialidase S (SS) or <I>Maackia amurensis</I> lectin (MAL), both specific for α2,3-linked sialic acid, or <I>Sambucus nigra</I> lectin (SNL), specific for α2,6-linked sialic acid. These results indicated that PSaV recognizes both α2,3- and α2,6-linked sialic acids for viral attachment and infection. Treatment of cells with proteases or with benzyl 4-O-β-D-galactopyranosyl-β-D-glucopyranoside (benzylGalNAc), which inhibits <I>O</I>-linked glycosylation, also reduced virus binding and infection, whereas inhibition of glycolipd synthesis or <I>N</I>-linked glycosylation had no such effect on virus binding or infection. These data suggest PSaV binds to cellular receptors that consist of α2,3- and α2,6-linked sialic acids on glycoproteins attached via <I>O</I>-linked glycosylation.</P></▼1><▼2><P><B>Author Summary</B></P><P>Although enteropathogenic sapoviruses and noroviruses are leading causes of acute gastroenteritis in both humans and animals, the study of viral pathogenesis and immunity of these ubiquitous pathogens has been hampered due to the lack of a fully permissive cell culture system. Porcine sapovirus Cowden strain provides a suitable system that can be used to identify the molecular mechanisms of viral pathogenesis. Previous studies have shown that carbohydrates and glycolipids play important roles in the attachment of members of the <I>Caliciviridae</I>; histo-blood group antigens (HBGAs) are used by <I>Norovirus</I> genogroups I to IV, as well as members of the <I>Lagovirus</I>, and <I>Recovirus</I> genera, whereas terminal sialic acid is recognized as a receptor for feline calicivirus and murine norovirus. To date, however, the role of carbohydrates in the life cycle of sapoviruses has remained largely unknown. We found that porcine sapovirus binds to susceptible host cells through both α2,3- and α2,6-linked terminal sialic acids which are attached to <I>O</I>-linked glycoproteins. These efforts, findings and insights will significantly contribute to a better understanding of the sapovirus life cycle.</P></▼2>
