목 적 : 신생아중환자실에서 미숙아들의 치료 중 흔히 패혈증을 경험하며 중요한 합병 소견으로 혈소판 감소증을 볼 수 있다. 최근 보고에 의하면 그람 음성균이나 진균에 의한 감염에서 그람 양성균에 비해 혈소판 감소증이 더 심하다는 보고가 있다. 본 연구자들은 패혈증을 나타낸 원인균들 사이에 혈소판 수치의 변화 정도와 패혈증 시 평균 혈소판 용적의 변화를 비교해 보고자 본 연구를 시행하였다. 방 법 : 2001년 1월부터 2006년 6월까지 원광대학교 의과대학병원 신생아 중환자실에 입원하여 치료받은 2,000 g 이하의 미숙아중 패혈증으로 확진된 미숙아 36명을 대상으로 의무기록지를 이용하여 후향적으로 조사 분석하였다. 환아들은 원인균에 따라 그람 양성균군($1,521{\pm}309g,\;31.3{\pm}2.9$, 15명), 그람 음성균군($1,467{\pm}290g,\;30.6{\pm}3.6$, 17명), 진균군($1,287{\pm}205g,\;30.0{\pm}3.9$, 4명)으로 분류하고 이들의 패혈증 증상 출현 3-5일전 시기, 패혈증 증상 출현 시기, 최저 혈소판수치를 보인 시기의 혈소판수치를 각 군별로 비교하였으며, 전체 환아에서 패혈증 출현 시 평균혈소판용적의 변화를 조사하였다. 결 과 : 패혈증을 일으킨 원인균별 분포는 그람음성균 17례(47.2%), 그람양성균 15례(41.7%), 진균 4례(11.1%)였으며, 이중 표피포도알균이 9례(25%)로 가장 많았고, 혈소판 감소증은 $100{\times}10^9/L$이하를 기준 시 88.9%, $150{\times}10^9/L$이하를 기준 시 94.4%이었으며, 혈소판 감소가 $100{\times}10^9/L$ 이하를 보인 빈도는 그람 음성균군 전례로 양성균군 11례(73.3%)에 비해 의의 있게 많았다(P<0.05). 패혈증 증상 출현시기의 혈소판 수치는 그람 양성균군에 비해 그람 음성균군에서 의의 있게 감소하였으며(P<0.05), 진균군에서도 감소하였으나 의의는 없었다. 최저 혈소판 수치를 보인 시기의 혈소판 수치도 그람 양성균군에 비해 그람 음성균군에서 의의있게 감소하였으며(P<0.01), 진균군에서도 감소하였으나 의의는 없었다. 최저 혈소판 수치를 보인 시기에 도달하는데 걸리는 시간은 원인균별 사이에 차이가 없었으며, 혈소판 수치가 $100{\times}10^9/L$ 이하, $150{\times}10^9/L$ 이하가 유지되었던 시간도 그람 음성균군에서 약간 길었으나 의의는 없었다. 혈소판 감소율의 비교에서는 패혈증 증상 출현 시기, 최저 혈소판수치를 보인 시기 모두 그람 양성균군에 비해 그람 음성균군에서 의의있게 감소하였으며(P<0.05), 진균군에서도 감소하였으나 의의는 없었다. 평균 혈소판 용적은 패혈증 증상 출현 전에 비해 최저 혈소판수치를 보인 시기에 의의 있게 증가 하였다(P<0.05). 결 론 : 그람 음성균에 의한 패혈증에서 그람양성균보다 혈소판 감소가 더 심하였다. 그리고 진균감염에 의한 패혈증에서도 그람양성균에 비해 혈소판 감소를 보였으나 의의는 없었으며 이는 대상 환아가 적기 때문으로 사료되었다. 또한, 패혈증시 평균혈소판용적의 증가를 보여 이러한 소견들은 미숙아들의 패혈증 진단과 치료에 도움이 되리라 생각된다. Purpose : Sepsis is a common complication in Neonatal Intensive Care Units (NICU), seen especially in low birth weight (LBW) infants. A recent study showed that fungal or gram-negative sepsis is associated with a greater degree of thrombocytopenia than is seen with gram-positive sepsis. So, this study was undertaken to examine the platelet counts and platelet indices in LBW infants during episodes of sepsis. Methods : We analyzed 36 cases with culture-proven sepsis on chart review in LBW infants admitted to the NICU at Wonkwang University Hospital from January 2001 to June 2006. Results : Patients were grouped by organism type: gram-positive bacteria ($1,521{\pm}309g$, $31.3{\pm}2.9wk$, 15/36), gram-negative bacteria ($1,467{\pm}290g,\;30.6{\pm}3.6wk$, 17/36), and fungi ($1,287{\pm}205g,\;30.0{\pm}3.9wk$, 4/36). The most common organism was Staphylococcus epidermis and the incidence of thrombocytopenia was 88.9%. When compared with infants with gram-positive sepsis, those with gram-negative sepsis had significantly higher incidences of thrombocytopenia, lower initial platelet count, lower platelet nadir, and greater mean percentage decrease in platelet count from before the onset of sepsis. Those with fungal infections were similar to gram-negative sepsis, but they were not significant because of the small number of patients. And mean platelet volume (MPV) in sepsis was increased more significantly in time of platelet nadir than before the onset of sepsis. Conclusion : We conclude that decrease in platelet count was significantly greater in gram-negative sepsis than gram-positive sepsis, and also greater than fungal sepsis-which was insignificant because of the small number of patients-in LBW infants. And elevation in MPV will be helpful in the diagnosis and treatment of sepsis in LBW infants.

삼성 이건희는 어떻게 기억되는가? : 부고기사 헤드라인 언어 분석을 통해

이완수(Wan Soo Lee),최명일(Myungil Choi) 한국언론정보학회 2021 한국언론정보학보 Vol.110 No.-

이 연구는 이건희 전 삼성 회장 부고기사 헤드라인에 나타난 사회적 기억을 뉴스 핵심어와 의미연결망 분석을 통해 체계적으로 살펴보았다. 이를 위해 모두 158건의 부고기사(보수일간지 73건, 진보일간지 25건, 경제일간지 60건)의 헤드라인에서 수집한 2,405개의 단어를 분석했다. 언어 분석결과를 보면, 이건희에 대한 언론의 평가적 언어는 매우 긍정적이었다. 이건희에 대한 주요 기억언어는 ‘세계’, ‘반도체’, ‘초일류’, ‘혁신’, ‘글로벌’, ‘성장’ 등으로 나타나 반도체를 무기로 글로벌 시장을 주도하는 미래의 초일류 혁신기업을 지향했던 기업인으로 기억되었다. 부정적 언어는 ‘무노조 (경영)’ 이외는 발견하기 어려웠다. 연결망 구조 분석에서도 이건희에 대한 언론의 평가는 ‘반도체’, ‘혁신’, ‘세계’, ‘글로벌’, ‘초일류’, ‘도전’, ‘성장’, ‘인재’, ‘스마트폰’, ‘미래’, 그리고 ‘신 경영’ 등의 핵심어가 중심적인 위치를 차지해 초일류를 지향하는 미래 지향적 글로벌 기업 구축에 힘썼던 기업인이었음을 강조했다. 또한 이건희 부고기사에 나타난 하위집단 분석에서는 그가 생전에 추구했던 가치와 정신이 두 가지 핵심적 내용으로 압축되었다. 하나는 삼성 신화를 일군 요인으로서 반도체를 중심으로 스마트폰, 디자인, 일류제품 등이 상호 연결되어 나타났고, 다른 하나는 그의 경영철학으로서 글로벌, 세계, 초일류, 신경영, 인재와 같은 언어가 서로 연결되어 강조되었다. 이런 언어 선택은 신문 간 이념에 따라 차이가 없었다. 우리는 언론이 어떤 인물의 삶과 죽음을 기록할 때 사회적으로 수용되지 않는 일탈적 행동이나 속성은 무시하는 대신에, 현재의 사회적 가치와 미덕에 부합하는 쪽으로 의미를 재구성하거나 상업적 이해관계에 따라 우호적 평가를 한다는 이론적 시사점을 제시했다. This study examined the social memory on the former Samsung Chairman Lee Kun-hee by analyzing the language in the newspaper obituaries. The analysis results showed the media’s memory of Lee Kun-hee is very positive. The main language of memory for Lee Kun-hee was “world-class”, “semiconductor”, “innovation”, “future”, etc. Negative language was difficult to find except ‘non-union (management)’. His life was recorded as making an absolute contribution to developing Samsung into a world-class company. In the analysis of the network structure, the evaluation of Lee Kun-hee was recoded with key words such as “semiconductor”, “innovation”, “world”, “global”, “top-class”, “challenge”, “growth”, “talent”, “smartphone”, “future”, and “new management”. The choice of language did not differ by the ideology of the newspapers. Several interesting values and virtues are found in the media’s memory of Lee Kun-hee. The first is the first-class spirit. The media especially emphasizes that Lee Kun-hee pursued a top-notch company, not just an ordinary company. The second is technology-centricity. Lee Kun-hee was remembered as a businessman who emphasized values related to technology such as “semiconductor”, “innovation” and “design”. The third is global orientation. The media emphasizes that Lee Kun-hee was at the center of making Samsung a company that competes in the global market, not the domestic market. The fourth is global orientation. The media emphasizes that Lee Kun-hee was at the center of making Samsung a company that competes in the global market, not the domestic market. The fifth is the spirit of innovation and challenge. The media emphasizes that Lee Kun-hee was a businessman who pursued innovation and a spirit of challenge through the words “myth,” “innovation,” and “challenge.” We discussed the point that the media reconstructs meaning in accordance with current social values and virtues while ignoring socially unacceptable deviant behaviors or attributes when recording the life and death of a person.

경제뉴스, 경제상황, 소비자 기대심리 그리고 소비행위의 상호 속성 의제설정 관계에 대한 시계열 분석

This article sets out to examine the direction and functions of the dynamic agenda setting of economic issues through the vector autoregression (VAR) and regression analyses. We have investigated the newly-compiled Korean media tone index of economic news, the state of the economy, consumer expectations and consumer behaviors. Our results show bilateral influence running between the actual state of the economy and consumer expectations concerning the economy. In addition, the tone of the media coverage of economic news has an immediate influence on the direction of consumer expectations. Accordingly, the domestic media tend to play the role of agenda setters pertaining the people's perception of the current economy. The agenda-setting function of the media coverage is greater in periods of business contraction than those of business expansion. The tone of media coverage, which has been adopted toward a possible downturn in business activity, tends to relate significantly to the comsumer expectations even after controlling major economic indicators. Changes in consumers' future expectations are analyzed as having the character of self-fulfilling prophecies that influence the actual level of consumption activity. Through this research, we have found that while the press and media cover the current economy negatively without reflecting the over-all state of the economy, they may in fact insist negative influences on people's real economic activities. This has happened although the media might not have intended to do so. Consequently, the policy authorities will be confronted with the need to communicate effectively with various economic agents including the press, firms and consumers concerning their own assessment or interpretation of the state of the economy. On the basis of this finding that the tone of economic reporting can exercise a substantial influence on the nation's economy, we discuss the future agenda setting research in and outside of South Korea and explore the possibility of applying the more complex time series methodology to this area of research.

This study comparatively analyzed differences in the pathways and influences of usage of channels for communication on the global COVID-19, risk perception, and preventive behavior at the personal and collective levels. A response sample t-test was first performed to estimate differences in related variables at the personal and collective levels, and a path analysis was performed to establish the pathways and influences among the relevant variables. The results showed that in the personal-level analysis, respondents indicated that they used the Internet mainly to find information about COVID-19 risks, but predicted that other people primarily used social media, newspapers, and television. In terms of social communication as a means of acquiring information, no difference was found between the individual respondents and others. Respondents also predicted that others would perceive the risks associated with COVID-19 to be greater than they did. In terms of behavioral response, they predicted that others would avoid contact with others and express a stronger sense of anger toward government policies compared with themselves. At the personal level, comparative analysis of pathways and influences between risk perceptions and preventive behaviors according to information channel showed higher levels of TV viewing, conversations with others, and Internet usage to be associated with stronger perception of COVID-19 risks. Stronger risk perception was associated in turn with increased avoidance of interpersonal contact and anger toward government policies related to the pandemic. In the collective-level analysis, higher levels of TV viewing, conversations with others, and social media usage were associated with stronger perceptions of COVID-19 risks. Risk perception was also found to be positively associated with avoidance of interpersonal contact and anger toward government policies at the collective level. An examination of moderating effects to identify significant differences according to variable pathways showed a significant influence between social media usage and the risk perceptions of others, rather than those of the individual respondent. Theoretical and practical implications are discussed.

출판기술의 역사적 변천과 출판인재상의 가치변화

이완수(Lee, Wan Soo) 한국출판학회 2020 한국출판학연구 Vol.46 No.1

오늘날 미디어 환경을 지배하고 있는 스마트 미디어시대 출판편집인에게는 특히 몇 가지 특별한 조건이 필요하다. 첫째는 기능적인 사고에서 인문학적 사고를 할 수 있어야 한다. 오늘날 출판 종사자는 과거의 기술적이고, 기능적인 접근방식에서 사람의 삶의 의미와 가치에 대한 본질적인 요소를 내면적으로 이해하고 성찰할 수 있는 인문학적 사고가 중요하다. 둘째는 문자적 사고에서 디자인적 사고로 전환할 필요가 있다. 과거에는 활자라는 수단을 통해 인간간의 소통을 수행했다면, 오늘날은 사진, 영상과 같은 이미지와 상징적 조작이 효과적인 커뮤니케이션 수단이 되고 있다. 이미지와 상징재현은 문자적 사고에 앞서 디자인적 사고가 더 유용하게 사용된다. 디자인적 사고는 사회현상을 사진으로 또는 영상으로 어떻게 재현해낼 것인가 하는 종합적인 능력을 의미한다. 셋째는 텍스트적 사고에서 하이퍼텍스트적 사고로 옮겨가야 한다. 활자중심 시대의 출판 종사자들은 문맥 자체의 의미를 잘 이해하고, 이를 전달하는 것으로 충분했지만, 하이퍼텍스트 중심 시대에는 정보의 조각을 조립하고, 연결하고, 의미구조화 하는 에디톨로지(editology)적인 사고를 필요로 한다. The publishing editors have been positioned differently from time to time. In the time of the mediation of the stone, the physical strength of the papyrus and the parchment paper, the talented people with excellent dexterity, the paper-working time, the technical talented people who can handle the machine, and the airwaves, the engineer. In the age of networked media such as the Internet and smart, there is a keen interest in understanding the technology and integrating talents who can carry out comprehensive thinking on the humanities. There are some special requirements for publishing editors in the smart media era that dominate the media environment today. The first is to be able to think about humanities in functional thinking. In today s technical and functional approach, publishers need a humanistic mind that can internally understand and reflect on the essential elements of the meaning and value of a person s life. Second, it is necessary to switch from literal thinking to design thinking. In the past, if human communication was carried out through the means of type, images and symbolic manipulations such as photographs and videos are effective means of communication. In image and symbolic representation, design thinking is more useful than literary thinking. Design thinking refers to the comprehensive ability of how to reproduce social phenomena in photographs or videos. Third, we must move from textual thinking to hypertextual thinking. In print-centered times, it was enough for publishers to understand and convey the meaning of the context itself, but in the hypertext-centric era, they thought of an editological thought to assemble, connect, and structure the pieces of information in need.

세월호 사고 뉴스 프레임의 비대칭적 편향성

이완수(Wan-Soo, Lee),배재영(Jae-Young Bae) 한국언론정보학회 2015 한국언론정보학보 Vol.71 No.3

이 연구는 프레임 개념과 편향성 개념을 통합적으로 연결해 재난 사고 뉴스의 정치사회적 의미를 해석했다. 국내 언론이 세월호 침몰 사고라는 특수한 재난 사고의 문제 정의, 원인 해석, 도덕적 평가, 그리고 사후 처방을 제시하는 과정에 어떤 프레임을 더 편향되게 배치했는지를 이론적으로 검정해 보았다. 또한 프레임의 편향성이 정치적 이념을 달리하는 보수 신문과 진보 신문 간에 어떤 차이가 있는지 비교 분석해 보았다. 내용 분석 결과를 제시하면 다음과 같다. 첫째, 세월호 사고 진단 프레임에서는 전체적으로 파편화>개인화>권위무질서>극화의 순으로 편향되어 있었다. <조선일보>는 파편화 편향성이, 한겨레는 권위무질서 편향성이 상대적으로 컸다. 둘째, 사고 평가에서는 책임 프레임>도덕적 프레임>문제 해결 프레임>사고 원인 프레임의 순으로 편향되어 나타났다. <조선일보>는 책임 프레임, 도덕적 프레임 편향적으로 사고를 평가했다. <한겨레>는 책임 프레임, 문제 해결 프레임 편향성이 두드러졌다. 셋째, 책임 소재 프레임에서는 정부>개인>조직의 순으로 편향되어 제시됐다. <조선일보>는 정부와 개인의 책임 편향성을 드러낸 반면에, <한겨레>는 상대적으로 정부에 책임을 더 강조하면서 조직에 대한 책임 편향성도 보였다. 넷째, 문제 해결 프레임에서는 전체적으로 주제적 프레임과 일화적 프레임 편향성이 엇비슷한 수준으로 나타났다. <조선일보>는 일화적 프레임으로, <한겨레>는 주제적 프레임으로 더 편향화하는 차이를 보였다. 세월호 사고의 평가와 해석에 대한 언론의 프레임 편향성과 함께 이념적 차이에 따른 언론 간의 편향성 차이를 사회적 맥락 차원에서 토론했다. This study analyzed the political and social significance of the disaster accident news with the frame and bias concept. In particular, this study confirmed theoretically how domestic media biased frame when it presents problem definition, causing interpretation, moral evaluation, and post-prescription on the ferry Sewol accident, In addition, the bias of the frame was analyzed comparing what is the difference between the conservative newspapers and liberal newspapers. Findings are as follows. First, in diagnosis of ferry Sewol accident, news slanted fragmentation frame>personalization frame>authority-disorder frame. The Chosun Ilbo focus on fragmentation bias, meanwhile Hankyoreh focus on the authority disorder relatively. Second, in accident evaluation, responsibility frame> moral frame> problem-solution frame. The Chosun Ilbo focus on responsibility frame and moral frame. But Hankyoreh focus on responsibility frame and problem-solution frame. Third, in the matter of responsibility, government frame>personal frame>organizational frame. Chosun Ilbo biased responsibility of the government and individuals, while the Hankyoreh is relatively more emphasis on government responsibility and the responsibility of the organization also showed. Fourth, in problem solving, thematic frame and episodic frame bias appeared as rough and level. Chosun Ilbo showed episodic frame, Hankyoreh showed thematic frame. News frame and bias as well as ideological differences of media on ferry Sewol accident was discussed in the context of the social dimension.

경제커뮤니케이션 효과이론에 대한 실증적 분석

이완수(Wan-Soo Lee),심재철(Jae-Chul Shim) 한국언론학회 2017 한국언론학보 Vol.61 No.1

This study tested path, direction, intensity, and persistence of the mutual effects of the four economic communication variables, the Korean economic news, objective economic reality, perceptions of subjective economic reality, and presidential job approval. In order to investigate the characteristics and structure of the Korean economy in different political and economic conditions, the vector-autoregression (VAR) model and impulse and response function (IRF) were applied. The results of the analysis are as follows. When media tone has turned negative, overall economic reality of the future is expected to deteriorate. Negative economic news tone also negatively affected the public’s view of my situation. In addition, president’s popularity and future economic prospects have influenced each other. In addition, when economic situation is bad than good, the response of the external impact is larger and lasts longer. This paper discussed the effect of economic communication on the Korean economy is different depending on the political and economic structure and conditions.

미디어의 경제현실 매개 기능에 관한 연구

이완수(Wan Soo Lee) 한국언론학회 2008 한국언론학보 Vol.52 No.1

This empirical analysis explores three vital questions: (1) how local economic news mediate national economic conditions? (2) what are the most concerned economic issues and how the public receive economic news? and (3) whether media coverage of economy fail to reflect real economic situation sufficiently, under the Roh Moo-hyun Government, which was constantly in confrontation with the media? First, the study find that local media, in general, failed to reflect the full picture of national economic conditions. Symmetric coverage patterns, where positive coverage increases in time of booming economy and negative coverage increases in time of sluggish economy, were not found. Second, local media coverages, overall, were more concerned in unemployment rates other than other major market indexes. it means the nation's employment conditions are the most vital economic issues and agenda for most Korean media outlets. Third, local media pay more interests in economic issues when the economy turns sluggish. Likewise, the public show more sensitive reaction to economic news when the economy turns sour. It suggests media coverage and aggregate public evaluation of economy may vary depending on real economic situation. Finally, even when controlling economic condition, local media coverage of economy did have certain effects on aggregate public evaluation of economy. This analysis investigates how media coverages of economy mediate economic conditions, and furthermore discusses whether media coverages of economy have certain agenda-setting and priming-effect functions.

미디어 현저성과 프레임 변화의 역동적 과정

이완수(Wan Soo Lee),심재웅(Jae Woong Shim),심재철(Jae-Chul Shim) 한국언론학회 2008 한국언론학보 Vol.52 No.1

The purpose of this study is to understand the dynamic process of news frame-changing in terms of the two-dimensional analytical framework proposed by Chyi and McCombs. Unlike previous news framing approaches focusing on issue-specific perspectives, this study defines a news frame as an aggregation of salient attributes of a news event and posits that news frames dynamically change over an event's lifespan. Specifically, we explore how news framing changed in coverage of the Virginia Tech shootings in 2007 and whether there were differences in the way news frames-changed between Korean and American newspapers. A content analysis was conducted to examine Chosun Ilbo and New York Times reportage of the shootings. Findings show dynamic changes in news frames used to cover the shootings over time, with each newspaper revealing its own pattern of news frame use. The implications of these findings for future research are discussed.
