하수관거 보수용 알루미나계 결합재 초속경 모르타르의 내구 특성

김은호,이병재,이선목,김윤용 한국건설순환자원학회 2022 한국건설순환자원학회 논문집 Vol.10 No.4

이 연구에서는 하수관거에 대한 수중불분리성 보수재료 개발을 위해 결합재 조성에 따른 내구성능을 평가하였다. 배합조건에 따른 모르타르의 내부 구조 분석 결과, CAC 배합의 경우 내식성 문제가 야기될 수 있는 Ca(OH)2를 형성하지않고 알루미나겔(Al2(OH)3)를 형성 함으로서 내식성이 우수한 것으로 확인되었다. 압축강도 시험결과, OPC가 가장 낮은 강도를 나타내었으며, CAC100 > CAC100P > C12A7 > CSA > CAC80순으로 나타나 기존연구결과와 유사한 경향을 나타내었다. 염소이온침투저항성 및 동결융해시험 결과 동일한 내구성능을 나타내었으며 알루미나시멘트(CAC 및 C12A7의) 계열은 OPC 보다 우수한 경향을 나타내었지만 CSA는 내부 팽창균열로 인해 내구성능이 낮은 것으로 판단된다. 화학저항성 시험결과, CAC100P 배합이 가장 우수한 화학저항성을 나타내었다. 이는 보수재 내부에 형성된 알루미나겔과 폴리머 분자가 결합하여매트릭스가 치밀해졌기 때문으로 판단된다.

VOCABULARY NEGOTIATION IN THE KFL CLASSROOM: LANGUAGE LEARNING OPPORTUNITIES THROUGH INTERACTION

김은호 계명대학교 한국학연구원 2015 Acta Koreana Vol.18 No.2

Using the micro-analytic framework of conversation analysis, this study demonstrates Korean language learners’ varying repair strategies when facing vocabulary production problems. The purpose of this study is twofold: (1) to explore the ways in which Korean L2 learners co-construct repair sequences for vocabulary negotiation and (2) to advance our understanding of how learning opportunities are created in Korean as a Foreign Language (KFL) classroom interaction. The data analyzed for this study are drawn from approximately nineteen hours of Korean as a second language classroom conversations, involving seven students and a teacher. It specifically investigates the various organ-izations of repair by two different language proficiency levels: advanced and intermediate. Analysis of moment-by-moment classroom interaction reveals that advanced and intermediate learners show different preferences and utilize repair sequences in differing ways in order to negotiate target vocabulary with interactants. Participants in the interaction move back and forth between the ongoing talk and the repair sequence and collaboratively resolve their problems in ways that create opportunities for learning. The analysis of these practices of “vocabulary negotiation” adds to a body of work that shows how students participate in building their own learning opportunities. Keywords: conversation analysis, learning opportunities, repair, vocabulary negotiation, KFL classroom interaction

A Conversation Analytic Study of Korean Sentence-ending Suffix –ci in the Language Classroom: Multiple Questions and Third Turn Position in Teacher Talk

김은호 고려대학교 언어정보연구소 2010 언어정보 Vol.0 No.11

Employing the methodological framework of conversation analysis (cf. Sack, Schegloff & Jefferson 1974), this study examines the ways in which the Korean sentence-ending suffix –ci affects the development of Korean classroom conversations. The aim of this paper is to reconsider previously proposed descriptions on -ci through a close examination of the concrete activities through which the suffix –ci is employed for the interactive management of talk-in-interaction, rather than speculating on the participants’ psychological states based on the analyst’s intuition or theoretical assumptions. –Ci has often been identified as a suffix serving a function of confirmation-request or an acknowledgement token expressing agreement with interlocutor’s stance (Choi 1995; Kawanish and Sohn 1993; Lee 1999; Martin 1992; Sohn 1999; Suh 2001). -Ci indeed frequently occurs in those occasions. However, close examination of the sequential context, turn shape, intonation and embodied actions involved in each occurrence of –ci demonstrates the varying contribution this suffix can make in the development of interaction. The results of the current microanalysis of classroom interactions reveal that the suffix –ci is recurrently utilized in the third position in teacher talk (Mehan 1979; Lee 2007) and multiple questions (Gardner 2004; Kasper and Ross 2007).

Negotiating opinion and the use of Korean interpersonal modal ending in the KFL classroom

김은호 국제언어문학회 2015 國際言語文學 Vol.- No.32

This paper presents a sequential analysis of the interactional uses of the Korean interpersonal modal ending -canh- in opinion-negotiation sequences of English-speaking learners of Korean, observed in two different task formats, i.e. teacher-fronted discussion and student-led debate. Using the methodological framework of conversation analysis, this study provides a detailed account of the use of -canh- in each task type. A total of 89 opinion-negotiation episodes were identified. Overall, the collection of this study shows two distinctive features: (i) in teacher-fronted discussion, -canh- is exclusively used to give accounts. (ii) in student-led debate, -canh- is predominantly utilized to perform disagreements. Findings show that the choice of task format constrains range and functions of -canh- enacted by the learners, highlighting the influence of minor contextual differences. Given the importance in such interactional contexts of students performing to the best of their abilities, these findings promote implications for teaching practice in KFL classrooms.

공익연계 마케팅 소구방식의 효과 : 사회적 비교, 공익연계 마케팅 기부 형태 및 독자성-융화성을 중심으로

김은호 한국광고학회 2022 광고학연구 Vol.33 No.6

본 연구는 사회적 비교(자기비교, 타인비교)와 공익연계 마케팅의 기부 형태(돈 기부, 시간 기부)에 따른 구매의도의 차이를 도덕적 정체성(내면성, 상징성)의 차이와 소비자의 내적성향(독자성, 융화성)을 중심으로 확인하였다. 연구 결과, 자기비교 조건에서는 타인비교 조건보 다 내면성이 촉발되었다. 하지만 상징성은 사회적 비교 방식에 따른 차이가 나타나지 않았다. 또 한 사회적 비교와 공익연계 마케팅 기부 형태에 따른 구매의도에 상호작용이 통계적으로 유의했 다. 자기비교 조건에서는 시간 기부와 금전 기부 형태 간 구매의도의 차이는 없었지만, 타인비교 조건에서는 시간 기부보다 금전 기부 조건에서 구매의도가 높았다. 자기비교 조건에서는 내면성 이 기부 형태와 상관없이 매개하는 것으로 나타났지만, 상징성은 매개하지 않는 것으로 나타났 다. 또한 타인비교 집단에서, 시간 기부 형태에서 내면성이 구매의도에 매개하였으나, 다른 조건 에서는 기부 형태에 따른 내면성과 상징성의 매개효과는 없었다. 사회적 비교 방식, 공익연계 마 케팅 기부 형태와 독자성-융화성이 구매의도에 미치는 효과의 삼원변량분석 결과, 삼원상호작용 효과가 통계적으로 유의했다. 융화성이 높은 소비자들은 타인비교 조건에서 금전 기부보다 시간 기부에서 높은 구매의도가 나타났다. 반면 독자성이 높은 소비자들은 사회적 비교 방식과 공인 연계 마케팅 기부 형태에 따른 구매의도의 차이가 통계적으로 유의하지 않았다.

Temperature Changes Caused by 13-MeV Proton Irradiation at the Interface of a Pyrex Glass and a Silicon Wafer

김은호,노승정,이두형,김희수,현준원,공영조 한국물리학회 2006 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.48 No.4

Wafer-bonding techniques are key issues for the commercialization of microelectromechanical system(MEMS) devices. We propose a new wafer-bonding method that uses localized heating of the bonding interface at the Bragg peak of the proton beam. The energy absorbed in pyrex glass due to the proton-beam irradiation was numerically calculated for various proton energies by using the stopping and range of ions in matter(SRIM) program. 13-MeV proton beams were used to irradiate the surface of pyrex glass mounted on a silicon wafer, and the interface temperature change was measured as a function of the irradiation time at various beam currents. The pyrex glass and the silicon wafer had the same sizes of 10 mm × 10 mm. The thicknesses of the pyrex glass and the silicon wafer were 1 mm and 0.65 mm, respectively. At a fixed beam current, the interface temperature change showed a rapid increase before 50 seconds and the increase became very slow after 50 seconds. The final interface temperature was found to be determined by the proton beam current, and the final temperature increased with the beam current.

학문 목적 한국어 쓰기에서 나타난 자료 사용의 양상: 중국인 대학원생의 쓰기 자료 분석을 중심으로

김은호 대구대학교 다문화사회정책연구소 2023 현대사회와 다문화 Vol.13 No.2

The purpose of this study is to examine the pattern of the source use of Chinese international students enrolled in graduate schools in Korea. In order to achieve the research purpose, this study collected the writing data of 11 international students in master’s course at a university in Seoul for 4 semesters. A qualitative analysis of the collected texts was used as the main method, and a quantitative analysis was also performed through a sentence similarity check software program to examine the distribution of the analysis data. The results of in-depth interviews at the beginning and end of the semester were also synthesized to broaden the understanding of the data. As a result of the analysis, there was no generalized developmental pattern in the source use ability, It was found that all of the study participants had difficulties in using sources in academic writing, and showed several characteristics in the use of sources. First, research participants excessively use paraphrasing among the methods of using academic writing sources. Second, few direct quotation, known as the easiest way to use sources, have appeared. Third, the rate of source integrating was lower than that of direct quotation, and very few were found by some superior learners. Based on the results of the study, it insists on the reinforcement of writing education.
