폴리우레탄-실리카 복합 발포체의 합성 및 물성에 관한 연구

강현석 ( Hyeon Seok Kang ),김상범 ( Sang Bum Kim ) 한국공업화학회 2020 공업화학 Vol.31 No.1

본 연구에서는 폴리우레탄-실리카 복합 발포체를 합성하여 복합 발포체의 단열 특성 및 기계적 물성을 분석하였다. 폴리우레탄-실리카 복합 발포체를 합성하기 위해 폴리에스테르-실리카 복합 폴리올을 합성하였다. 폴리에스테르-실리카 복합 폴리올은 실리카 졸과 모노머 상태의 다이카복실산(dicarboxylic acid), 글리콜(glycol)과의 중합 반응을 통해 합성하였다. 합성된 복합 폴리올을 이용하여 폴리우레탄-실리카 복합 발포체를 합성하여 물성을 분석하였다. 폴리우레탄-실리카 복합 발포체의 열전도도는 HPUF0, HPUF1, HPUF3, HPUF5 모두 큰 차이가 없는 것을 확인하였다. 압축강도는 실리카 함량이 증가함에 따라 HPUF0보다 증가하였으며 HPUF0보다 HPUF5가 약 25% 정도 기계적 물성이 향상되는 것을 확인하였다. In this study, polyurethane-silica composite foams were synthesized to analyze thermal insulation characteristics and mechanical properties. In order to synthesize polyurethane-silica composite foams, polyester-silica composite polyols were first synthesized via a polymerization reaction with silica sol, dicarboxylic acid and glycol in monomer state. Physical properties of polyurethane- silica composite foams synthesized using the composite polyols were analyzed. From the thermal conductivity analysis, no significant differences among HPUF0, HPUF1, HPUF3 and HPUF5 were found. The compressive strength of polyurethane- silica composite foams increased as the silica content increased. The mechanical property of HPUF5 was also about 25% higher than that of HPUF0.

강현석(Kang Hyeon Seok) 한국사회언어학회 2015 사회언어학 Vol.23 No.3

This study, first, examines the present international status/prestige of Korean on the basis of the number of speakers, the number of countries where it is spoken, the size of GDP by language, and the comprehensive evaluation considering other factors as well as the number of speakers and the economic factor. This research, next, predicts the ‘rather dismal’ future status of Korean based on the predicted statistics of Koreaʹs future population and potential economic growth rate provided by domestic and international organizations. Finally, implications of the findings of this study are discussed and some suggestions on governmental policies, which could be of help to maintain the current international status of Korean, are given.

수중글라이더는 일반적으로 프로펠러 추진방식이 아닌 부력과 중력의 변화를 이용하여 추진하는 방식으로 거동한다. 본 논문에서는 가오리형 수중글라이더(Ray-type underwater glider)에 대한 유체저항성능 및 운동성능 해석을 통해 선체의 선형설계를 수행하였다. 동체 내부에 이중부력엔진(Dual buoyancy engine)과 이동질량체(Mass shifter)를 구성하여 가오리형 수중글라이더의 추진매커니즘을 소개하고, 유체저항을 최소화하는 선형설계를 위해 전산유체해석(Computational fluid dynamics analysis)을 이용한 유체저항성능 해석을 수행하였다. 또한 수중글라이더의 기구학적 특성 및 운동특성을 반영한 운동시뮬레이터를 설계하여 운동성능을 해석하였으며, 설계된 수중글라이더의 선형과 CFD해석을 통한 유체저항성능해석의 유효성을 확인하기 위해 어뢰형(Torpedo-type)의 운동성능과 비교·분석하였다.

카카오톡 대화에서의 경어체 종결어미의 변이 양태에 대한 다중변인분석 연구

강현석(Kang, Hyeon-Seok),김민지(Kim, Minji) 한국사회언어학회 2018 사회언어학 Vol.26 No.1

On the basis of KakaoTalk conversation data, this paper investigates the variations found in the use of honorific final endings, expecially haeyo and hapsyo styles. For this study we collected 3,087 tokens of honorific final endings from the dialogue of 8 KakaoTalk group chat rooms. Through multivariate analyses using Goldvarb and LVS, we examined whether the linguistic and external constraints, which were claimed by Kang (2011) to constrain the usage of haeyo and hapsyo styles in spoken language, also operate in the KakaoTalk dialogues. The results of the analyses revealed not only far more variants in the KakaoTalk data (12 variants of haeyo and 6 variants of hapsyo ) than in spoken language but also various additional variants realized with pronunciation spelling and partial omission of final endings. As in the spoken language, ‘sentence type’, ‘speaker s gender’, ‘rituality of utterance’, and ‘formality of situation’ were analyzed as constraints which had a strong effect on the variation. In the data examined, besides haeyo and hapsyo styles, new honorific styles of hao, hasoseo, seupjyo, handayo, hasem/hasam were also found. Two new types of variants which was not yet discussed in previous studies, were also observed in the data: variants of ‘syam’ and ‘syeom’ of hasem/hasam styles and two variants of ‘yo’ realized with consonant addition to the onset position.

충남 지역 화자들의 방언 구획, 방언 태도 및 인지에 대한 연구

강현석(Hyeon-Seok Kang) 한국사회언어학회 2010 사회언어학 Vol.18 No.2

This study examines Chungnam dialect speakers’ perceptual dialect boundaries, their images of Korean dialects, and also their auditory ability to distinguish the dialects. Thirty Chungnam residents participated in this research as subjects and performed four tasks: pile-sorting, description of dialect images, dialect recognition, and a short interview. The focus of the study was to examine the informants’ subjective dialect boundaries among Chungnam dialect and geographically adjacent Chungbuk, and Jeonbuk dialects, the informants’ images about these dialects, and their ability to distinguish the three. The results from the tasks suggest that speakers of Chungnam dialect perceive Jeonbuk dialect at least as close as or even closer than Chungbuk dialect. The results from the dialect recognition experiment also reveal auditory-perceptual similarity between Chungnam and Jeonbuk dialects. Chungnam dialect speakers were, in addition, analyzed as having relatively favorable images about their dialect.

인스턴트 메신저 카카오톡의 대화 자료에 나타난 ‘ 예 ’ 와 ‘ 네 ’ 의 변이 양상

This paper investigates the variations found in the use of ‘ye’ and ‘ne’ in the conversations of the mobile messenger KakaoTalk. This study was conducted based on the dialogues from the 159 KakaoTalk chat rooms, using the statistical package Language Variation Suite. As many as 17 variants of ‘ye’ and ‘ne’ were observed in the data analyzed compared to just the four variants of the speech data (Kang 2009), revealing a big difference between the two data types. Further, the ‘ne’ variants were absolutely dominant, comprising 90% of the tokens, making them gender-neutral in this variation. Regression analyses showed that ‘gender’ was the most important constraint influencing the variation: Men used the ‘ye’ variants 25% of the time, while women used them only 4% of the time. Age was another important factor: Older people used the ‘ye’ variants more than younger people. This study reveals that the new medium of net language (Crystal 2001) could produce radically different results from spoken language even when the same sociolinguistic variables are analyzed, and it may point to a new direction of research in variation theory.

This paper investigates the naming of coloanal treatment hospitals and clinics, examining their name types and the etymological origins of their names. The research data were collected from the Permanent Members Directory of the Korean Society of Coloproctology published in 2015. The major findings of the research are as follows: 1) The names of the hospitals and clinics were mostly composed of one or two component names. 2) Specialty treatment names and suggestive names were used much more often than location names, owners names, and owners college names, which were traditionally regularly used in the past. 3) Clipping transformations, letter transformations, and transformations to metaphoric/ambiguous expressions were often observed in the data in order not to violate the medical law which prohibits the use of body part names in the naming of hospitals and clinics. 4) Much more Chinese-Korean names were used than native Korean and foreign names. 5) Strong socioeconomic motivations are observed in the naming of coloanal treatment hospitals and clinics.

천안ㆍ아산지역어와 대구지역어에 나타나는 w탈락현상의 비교연구 - 대학생 언어를 중심으로

강현석(Kang Hyeon-seok),이장희(Lee Jang-hee) 한국사회언어학회 2006 사회언어학 Vol.14 No.2

  On the basis of 24 speakers" recorded speech this paper examines the variable deletion of w in two regional dialects, Cheonan-Asan Korean and Daegu Korean. Varbrul analyses are conducted using the 3965 tokens of (w). Results of the combined and separate analyses show that the two dialects are subject to very similar constraints in w deletion, though deletion rates and the strengths of the constraints on the deletion process are somewhat different. It is suggested that the syllable structure of young Daegu Korean speakers might be rather different from that of older speakers, and that dialect leveling from contact with Standard Korean could be the cause of this change.
