오창우(Chang-Woo Oh),배상일(Sang-Il Bae),문영민(Young-Min Moon),양현경(Hyun Kyoung Yang) 한국방사선학회 2022 한국방사선학회 논문지 Vol.16 No.6

고 에너지 전자선 치료 시 차폐체로 사용되는 납을 대체할 수 있는 3D 프린터 소재를 찾기 위해 MCNP6 프로그램을 사용하였다. 고 에너지 전자선을 방출하는 선형가속기의 PDD(Percent Depth Dose), Flatness, Symmetry를 측정하고, MCNP6로 선형가속기를 모의 모사 후 비교하여 실측과 모의 모사와의 선원항이 일치함을 확인하였다. 납 차폐체를 모의 모사하여, 흡수선량의 95 % 이상을 차폐할 수 있는 납 차폐체의 적정두께를 선정하였다. 3 mm 두께의 납 차폐체에 대한 흡수선량 데이터를 기준으로 하여 ABS + W(10%), ABS + Bi(10%), PLA + Fe(10%) 소재들의 1, 5, 10, 15 ㎜ 두께 별로 모의 모사로 분석하여 차폐성능을 분석하였다. 3D 프린터로 각각의 시제품을 제작하여 모의 실험과 같은 조건으로 측정하여 분석한 결과 ABS+W(10%) 소재가 최소 10 mm 이상의 두께로 형성되었을 때, 3 mm 두께의 납을 대체할 수 있는 차폐성능을 가지는 것을 확인하였다. 주사전자현미경(SEM)과 EDS 스펙트럼을 이용하여 ABS + W(10%) 소재의 원소조성 및 표면형상을 분석하였다. 이러한 결과를 통해, 상용화 된 납 차폐체를 ABS + W(10%) 소재로 대체하면 납과 같은 차폐효과를 낼 뿐만 아니라 3D 프린터를 이용하여 환자 맞춤형으로 제작할 수 있어 고 에너지 전자선 치료에 매우 유용할 수 있음을 확인하였다. To find a 3D printer material that can replace lead used as a shield for high-energy electron beam treatment, the shielding composites were simulated by using MCNP6 programs. The Percent Depth Dose (PDD), Flatness, and Symmetry of linear accelerators emitting high-energy electron beams were measured, and the linear accelerator was compared with MCNP6 after simulation, confirming that the source term between the actual measurement and simulation was consistent. By simulating the lead shield, the appropriate thickness of the lead shield capable of shielding 95% or more of the absorbed dose was selected. Based on the absorption dose data for lead shield with a thickness of 3 mm, the shielding performance was analyzed by simulating 1, 5, 10, and 15 mm thicknesses of ABS+W (10%), ABS+Bi (10%), and PLA+Fe (10%). Each prototype was manufactured with a 3D printer, measured and analyzed under the same conditions as in the simulation, and found that when ABS+W (10%) material was formed to have a thickness of at least 10mm, it had a shielding performance that could replace lead with a thickness of 3mm. The surface morphology and atomic composition of the ABS+W (10%) material were evaluated using a scanning electron microscope (SEM) and an energy dispersive X-ray spectrometer (EDS). From these results, it was confirmed that replacing the commercialized lead shield with ABS+W (10%) material not only produces a shielding effect such as lead, but also can be customized to patients using a 3D printer, which can be very useful for high-energy electron beam treatment.

TV가 재현하는 다문화 현실에 대한 결혼이주여성의 재귀적 해독

오창우 ( Chang Woo Oh ),이현주 ( Hyun Ju Lee ) 한국지역언론학회 2011 언론과학연구 Vol.11 No.3

본 연구는 텔레비전이 재현하는 결혼이주여성의 현실에 대하여 실제 수용자인 결혼이주여성들이 어떻게 받아들이고 해독하는지를 심층인터뷰를 통하여 살펴보았다. 즉, 텔레비전 속에서 보여지는 자신들의 모습이 실제 자신들의 삶을 얼마나 현실적으로 묘사하고 있다고 생각하며, 텍스트 속에 나타난 자신들의 모습에 대해 어떤 태도를 보이고 있으며, 결혼이주여성들과 텍스트의 상호작용성은 이들의 정체성에 어떤 영향력을 행사하고 있는가를 살펴보고자 하였다. 심층인터뷰 결과 결혼이주여성들은 자신들의 사회적 위치에 따라 다양한 해독을 하고 있었다. 그들은 학력, 교육수준, 직업에 따라 미디어에서 재현하는 자신들의 모습에 대해 의문점을 제시하거나 수용하는 차이점을 보여주었다. 또 능동적 수용자로서 텍스트와의 상호작용을 통해 미디어에서 재현되는 객관화된 주체에 대하여 주관적 주체자로서 다양한 의견을 표명하고 있음을 확인할 수 있었다. This research problem dealt with in-depth interview with migrant marriage women who watch television texts as audience. Through in-depth interview, the research found that the immigrant marriage women tended to interact with and interpret the text in various ways as their social status and backgrounds vary. This illustrates that the immigrant marriage women viewed as subalterns who cannot speak with their own voice are in fact active cultural subjects who can make their own opinions. Therefore, it is necessary for media to portray the immigrant marriage women in accordance with diverse ethical and national backgrounds they have. This article also demonstrates that media play a central role in producing stereotyped image of a minority group; therefore, media should play a critical role to convey other minority groups with respect to multiple and equally valid cultural entity and perform its role to overcome our exclusively nationalist-oriented ideology.

상품 관여도 수준에 따른 광고텍스트의 구조적 특징 차이

오창우 ( Chang Woo Oh ) 한국지역언론학연합회 2006 언론과학연구 Vol.6 No.4

본 연구는 상품의 관여도 수준에 따라 광고에서 사용되고 있는 언어적 텍스트의 구조 및 발화형식은 어떻게 다르게 나타나며, 이러한 요소들이 궁극적으로는 소비자의 행동자극과 인식자극을 위하여 어떤 형태로 제시되는지를 밝히기 위한 것이다. 분석을 위하여 2003년도 광고물 115개와 1993년도 광고물 63개를 추출하였는데, FCB 플래닝 모델에 근거하여 고관여/이성 제품에는 자동차 제품을, 고관여/감성 제품에는 여성화장품을, 저관여/이성 제품에는 가정용품을, 저관여/감성 제품에는 빙과류 제품을 선정하였다. 이렇게 선정된 178개 광고물을 대상으로 광고 텍스트의 구조 및 문법적 특징을 분석하였다. 코딩은 총 6명이 3개조로 나누어 각 제품별로 분석하게 하였다. 분석 결과 나타난 결론은 다음과 같다. 첫째, 상품의 관여도 수준에 따라 광고에 사용된 광고 텍스트의 길이는 차별적으로 나타났다. 표제문에서는 제품간에 뚜렷한 차이가 발견되지 않았지만 전체 광고텍스트 길이는 자동차와 빙과류 사이에 분명한 차이가 나타났다. 또 1993년 광고에 비해 2003년도 광고에서 텍스트 길이가 짧은 것이 빈번하게 나타났다 둘째, 상품관여도 수준에 따라 광고텍스트의 구조적 특징은 다르게 나타났다. 자동차와 여성화장품에서는 ``자막+멘트``로 구성된 텍스트가 가장 많았으며, 빙과류 제품에서는 ``자막+멘트+모델``형식과 ``자막+모델대화`` 형식이 가장 빈번하게 나타났다. 셋째, 상품관여도 수준에 따라 화자-청자 구조는 다르게 나타났다. 자동차와 여성화장품 광고에서는 내레이터 발화가 가장 많이 나타나고 있었는데, 이는 화자가 청자인 시청자를 상대로 주관적인 전달방식을 의해 메시지를 전달하고 있음을 의미한다. 또 가정용품과 빙과류 제품에서는 ``모델간의 대화``형식이 가장 많이 나타났는데, 이것은 수용자들의 행동 동일시를 직접적으로 추구하는 방식이라고 할 수 있다. 결국 빙과류나 가정용품과 같이 저관여 제품 광고에서는 모델간의 대화를 통한 구체적인 정보를 소비자들에게 객관적으로 전달하는 형식을 채용하고 있는 반면 자동차나 여성 화장품과 같은 고관여 제품 광고에서는 보다 짧은 광고 텍스트를 통하여 자막과 내레이터 설명에 의존하는 주관적인 전달방식을 채용하고 있었다. 본 연구에서는 상품의 관여도 수준에 따라 자동차, 여성화장품, 가정용품, 빙과류 제품을 임의적으로 선정하였고, 각 관여도 수준에 해당하는 광고물을 추출하기 위하여 1993년도와 2003년도를 분석대상기간으로 설정하였는데, 이를 바탕으로 한 분석결과가 과연 상품관여도에 따른 광고 텍스트의 구조적 특징을 얼마나 정확하게 비교, 설명할 수 있는가 하는 문제가 가장 큰 한계점으로 지적될 수 있겠다. This paper intends to present: how differently the linguistic text structure and speech delivery format used in advertisements appears, depending on the level of product involvement; how is rhetoric presented to ultimately achieve awareness stimulation and action stimulation on the part of consumers. In order to make a comprehensive analysis for this paper, 63 commercials broadcasted in 1993 and 115 commercials broadcasted in 2003 were selected. Based on the FCB planning model, automobile products were chosenfor the high involvement/information search products, cosmetics for high involvement/emotional purchases, household products for the low involvement/information search, and ice cream products as a low involvement/emotional purchase product. The textual structure and grammatical character of the 178 advertisements were then analyzed. The coding was analyzed for each group of products by three groups totaling six people. The analysis returned the following conclusions: First, depending on the level of product involvement, the length of the advertising texts used had a distinct difference. In headlines, no clear difference was found, but in terms of the length of the entire block of text, a clear difference was apparent between automobile products and ice cream products. In addition, those printed in 2003 were shorter in overall length of text, than those printed in 1993. Second, depending on the level of product involvement, the structural factors of the advertising texts appeared differently. In automobiles and cosmetics, ``caption+comment`` format texts were used most frequently, while in ice cream products, the most frequent format was ``caption+comment+model`` and a ``caption-model conversation`` format. Third, depending on the level of product involvement, the structure between the speaker and the listener appeared differently. In advertisements for automobiles and cosmetics, a narrative delivery by a speaker was used more often, and in these cases, the speaker opted for a subjective delivery method, targeting viewers of the advertisement. Also, in household and ice cream products, ``conversation between models`` was used more often, which is a method that directly searches for action identification of consumers. In this research, automobiles, cosmetics, household products, and ice cream products were randomly selected depending on the level of product involvement, and in order to select advertisements that belong to each group of involvement level, with 1993-2003 selected as the target period of analysis. But it could be pointed out that the problem of how much the analysis results from this survey can help us accurately compare and explain the structural character of advertising texts depending on the level of product involvement, will be a major limit of this research.

공중의 심리적 기저 ‘인정받기’의 개념적 논의

오창우(Oh, Chang Woo) 계명대학교 사회과학연구소 2017 한국사회과학연구 Vol.36 No.1

“자기의식은 오직 인정된 것으로서만 존재할 뿐이다”(Hegel, 1807, 141/220) 이 논문은 한국 사회에서 하나의 도덕적 범주로서 호네트(Axel Honneth)의 인정개념의 수용 가능성을 모색하기 위한 것이다. 아울러 헤겔을 시작으로 하버마스와 호네트에 이르기까지 인정의 개념이 어떻게 다르게 나타나고 있으며, 특히 호네트에게 있어서 인정개념, 인정유형, 무시유형 등이 어떻게 설명되고 있는지를 살펴보았다. 또 PR의 실행에 있어서 공중(public)의 성격 진단 및 그들의 심리적 기저로서 인정 욕구에 대한 해석, 그리고 규범적 입장에서 중요한 도덕 범주로서 ‘인정문화’가 갖는 의미에 대해 논의하였다. 다양한 사회적 이슈에 반응하는 공중들은 강력한 인정욕구를 갖고 있다. 그래서 그들은 중요한 사회적 이슈의 논의 과정에서 자신들이 소외되거나 무시된다고 인식하는 경우에는 적극적인 저항 내지는 투쟁 양상을 나타낸다. 한편 공중 행동의 정당성을 설명하는 과정에서 무엇보다도 중요한 것은 공중의 자율성(autonomy)이다. 공중이 자율적으로 행동하지 않는 경우, 그들의 행위는 사회적 인정을 받을 수 있는 조건을 충족하지 못한다. 사회구성원 간의 인정의 또 다른 형태인 신뢰는 국가의 도덕성, 사회 구성원들 간의 경쟁의 정도, 자원의 공급과 수요의 균형성, 사회 내 지배적인 가치 및 정신, 사회체계의 자율성, 지배적인 커뮤니케이션 형태 등의 외부적 요인과 사회구성원들의 심성(心性), 타인을 대할 때의 목적성(目的性), 종교적 규범(規範) 등과 같은 내적 요인들이 복합적으로 작동한 결과라고 할 수 있다. This paper is to explore the acceptability of the recognition concept of Axel Honneth as a moral category in Korean society. In addition, it is examined how Hegel"s concept of recognition differs in Habermas and Honneth, and in particular Honneth"s recognition concept, recognition type, and ignorance type. It was also discussed in public relations about the general characteristics of the public as well as their need for recognition as a cause of their behavior. Responding to various social issues, the public has strong desire for recognition. When they think that they are alienated or ignored in the process of discussing social issues, they represent actions of resistance or struggle. On the other hand, the most important thing in explaining the legitimacy of public behavior is the autonomy of the public. If the public does not act autonomously, their conduct can not be granted social recognition. Trust, another form of recognition, is a combination of external factors such as morality of the state, the degree of competition among the members of society, the balance of supply and demand of resources, the dominant values and minds in society, autonomy of social systems, and internal factors such as the spirituality of the members of society, the purpose of serving others, and the norms of religion.

언론체계에 대한 Public Relations의 영향에 대한 고찰

오창우(Oh Chang-Woo) 한국언론학회 2000 한국언론학보 Vol.44 No.4

This study, borrowing Luhmann's system theory, examines how public relations, concretely press release, affects journalism and how the journalists assess press release. System theory examines how diverse' parts are integrated into the whole and expand to a system. For that reason, an individual phenomenon can be observed and understood only in relation to the whole system. Most empirical studies up to the present in the field of journalism seem to fail in identifying a concrete object of study. A German system theory is proposed here as an alternative approach to the study of journalism. Due to the following three features, system theory can significantly contribute to journalism research. ㆍConceptions of system theory makes it easier to mark a clear boundary of study in mass communication and/or journalism. It may contribute to acknowledge the study of journalism and/or mass communication as a legitimate independent discipline in the future. ㆍ System theory-based research can integrate the traditional theories like, for instance, the 'agenda-setting function of the mass media' and the 'news value study' into an extensive theoretical framework. ㆍ System theory-based research accepts the relation between reality and mass media reality as a centrally related problem. Understanding reporting as an active construction of reality, it refuses the traditional viewpoint in communication research in which mass media are described only as accomplishment of the wide copy-function. If journalism, thanks to system theory-based approach, can be identified as a concrete research subject, the basis for the classification between public relations, advertising, art and non-professional communication can be worked out. Namely, the subject matter of journalism research cannot be treated equal or be interchanged with mass media and publicity. This research assumes that journalists depend on press release because of the time limit and heavy work loads and that journalists evaluate their dependence on press release as reasonable, resulting in the similar reflection of press release in news writing among the dailies. Accordingly, five research questions were suggested. RQ1 : How much portion of the press release is reflected on the financial pages of the 6 dailies? RQ2 : How do journalists evaluate the 'self-related factors' and 'other-related factors' from diverse environmental factors which affect their speech and reporting? RQ3 : How do journalists in the economy department of the 6 dailies assess the quantity and quality of the press release from diverse organizations? RQ4 : How do journalists assess their degree of (in) dependence in the reporting process? RQ5 : How do journalists in the economy department of the 6 dailies judge the possible consequences of the use of press release? And what are the grounds for their judgment? This study was conducted in two ways; content analysis and questionnaire. To identify the influence of press release on news reporting, the news items of the economy department of the 6 dailies were analyzed. To identify the journalists' attitude to press release and their motivation to use it, several questions were asked to 40 journalists who cover the Ministry of Finance and Economy, the Finance Supervisory Commission and the Korea Stock Exchange. News items of the 6 dailies - Chosun Ilbo, Chungang Ilbo, Dong-A Ilbo, Hankook Ilbo, Hangyoreh and Kyunghyang Shinmun - were analyzed from 24 Apr. 2000 to 29 Apr. 2000. Two journalists who are independent from the 6 dailies were classified into 'press release news' and 'gather news'. After that, the size of the 'press release items' and the size of the 'whole page' were measured by the units of column line. The questionnaire were distributed and filled out for three days from 1 May 2000 to 3 May 2000 in the press room of the three organizations mentioned above. The results of this study show that on

언론체계의 인터뷰 내용 변형구조에 관한 연구

오창우(Oh Chang-Woo) 한국언론학회 2002 한국언론학보 Vol.46 No.4

Media system tends to penetrate other systems and thus increases its dependence on other social systems for reducing the complexity of media system itself. However, this tendency of penetration and dependence may transform other social systems into the media system in order to make other new systems familiar with media system. These days, the dependence of media system on PR system are rising. In a similar vein, the growing competition within media systems and the shortage of contents as a result of the expansion of the media systems enforce the media systems to participate in the transforming process for making all information from companies, organization, and other institutions look similar with media products. In this process, PR system actively uses media system for the benefits of PR system and further try to follow the programs of media system for publicizing its messages using media system. Interview, an active method of PR programs used by companies, organizations, and institutions, is very useful through which both media and PR systems can make possible more smooth inter-system activities, as well as to borrow useful outcomes from other systems. However, this interview can cause some ethical problems due to the fact that information from information providers can be distorted and thus result in some disadvantages. In addition, the interview method can threaten the speciality of PR system experts as well. Based on these concerns, this study investigates how media system reflects diverse information from our everyday activities in the process of media system's constructing reality. More specifically, this study focuses on the transformation process in which individuals, companies, organization, and other institutions publicize interview results. Consequently, this study emphasizes that both PR and media systems may lose credibility of the systems' activities in that media system uses PR system as an only tool without due regard for strategic goals, and, in reverse, PR system excessively equates its activities with media-oriented values and media system itself with no particular reason. Therefore, in order to facilitate a 'win-win' strategy for the benefits of both PR and media systems, this study argues that it is necessary to establish more strategic and acceptable standards from the angles of various programs of each system.

〈주도권토론〉 방식의 활용에 관한 연구

오창우(Oh, Chang-Woo) 계명대학교 사회과학연구소 2012 한국사회과학연구 Vol.31 No.1

In TV debate, <initiative discussions> was adopted to avoid formal and mechanical discussion and to reveal errors in logic of the opponent and to take advantage for strengthening self legitimacy. In addition, the goal of the introduction is to improve the dynamics of debate and to led to an interesting debate. An analysis of TV debate for the 5th Korean Nationwide local election shows that debaters did not know what <initiative discussion> is. They did not know how to take advantage of initiative opportunities and whom to ask. Also, in some cases even inappropriate questions or answers, and any given time to talk alone, then no question asked. Even the other candidates to favor <initiative discussions> may have operated. The proud and self-promotion as an opportunity, or litany, or discloses the shortcomings of the other, and personal attacks were often spent time.
