The primary purpose of this study is to identify the relationship between phonological change in the Korean language and its hypercorrection. To this end, this study further clarified the idea of hypercorrection, conditions, scope, etc. which had been rather unclear so fareto explain the relationship between phonological change and hypercorrection. To test the idea, conditions, etc. the study extracted hypercorrection examples in the Korean central dialect and investigated in which pattern the hypercorrections appeared in the actual literature by setting it as its secondary purpose. To this end, examples were extracted and quantified centering on palatalization and labialization and their development patterns were discussed. As a result, the hypercorrections in Korean central dialect were limited to the phonological change delivered from regional dialects. In this study, hypercorrection was recognized when the phonological environments were identical between the phonological change input part and alternant output part. In addition to this, the study discussed the possibility of different hypercorrection patterns according to social prestige. In this type of transformation under social prestige, the study looked at regions, social classes and vocabulary types to investigate different realization of hypercorrections. The Korean central dialect, first of all, was regarded more prestigious than regional dialects. It was also found that the language reflecting the upper class, rather than the language reflecting the mid class; and Sino­Korean words, rather than the native words in terms of lexicon type; were more socially prestigious thus, showing different hypercorrection patterns. Lastly, it was discussed that hypercorrection immediately appeared from the moment of phonological change or its acceptance and hypercorrection also occurred during active phonological changes or near the completion stage.

Purpose: Aerial application of chemicals with an agricultural helicopter allows for precise and timely spraying and reduces working labor and pollution. An attitude controller for an agricultural helicopter would be helpful to aerial application operator. The objectives of this paper are to determine the transfer function models and to estimate the handling qualities of a bare-airframe model helicopter. Methods: Transfer functions of a model unmanned helicopter were estimated by using NAVFIT and DERIVID modules of the $CIFER^{(R)}$ program to the time history data of frequency sweep flight tests. Control inputs of the transfer functions were elevator, aileron, rudder and collective pitch stick positions and the outputs were resulting on-axis movements of the fuselage. Results: Minimum realization of the transfer functions for pitch rate output to elevator control input and roll rate output to aileron control input produced second order transfer functions with undamped natural frequencies around 3.0 Hz and damping ratios of 0.139 and 0.530, respectively. The equivalent time delays of the transfer functions ranged from 0.16 to 0.44 second. Sensitivity analysis of the proposed parameters allowed derivation of minimal realization of the transfer functions. Conclusions: Handling quality of the model helicopter was addressed based on the eigenvalues of the transfer functions, corresponding undamped natural frequencies with damping ratios. The equivalent time delays of the lateral-directional motion ranged from 0.16 to 0.44 second, longer than the 0.1 to 0.15 second requirement for well-controlled typical manned aerial vehicles.

The aerial application using an unmanned helicopter has been already utilized and an attitude controller would be developed to enhance the operational convenience and safety of the operator. For a preliminary study of designing flight controller, a state space model for an RC helicopter would be identified. Frequency sweep flight tests were performed and time history data were acquired in the previous study. In this study, frequency response of the flight test data of a small unmanned helicopter was analyzed by using the CIFER software. The time history flight data consisted of three replications each for collective pitch, aileron, elevator and rudder sweep inputs. A total of 36 frequency responses were obtained for the four control stick inputs and nine outputs including linear velocities and accelerations and angular velocities in 3-axis. The results showed coherence values higher than 0.6 for every primary control inputs and corresponding on-axis outputs for the frequency range from 0.07 to 4 Hz. Also the analysis of conditioned frequency response showed its effectiveness in evaluating cross coupling effects. Based on the results, the dynamic characteristics of the model helicopter can further be analyzed in terms of transfer functions and the undamped natural frequency and damping ratio of each critical mode.

배영환,김동은,이효진,김의화,정용식,홍영기,이승구,Bae, Young-Hwan,Kim, Dong-Eun,Lee, Hyo-Jin,Kim, Eui-Hwa,Jeong, Yong-Sik,Hong, Young-Ki,Lee, Seung-Goo 한국섬유공학회 2008 한국섬유공학회지 Vol.45 No.2

The soybean/cotton blended fabrics were treated with two different commercial finishing agents to enhance the antimicrobial and deodorization activity. Also, we used the polymeric chitosan for improving the antimicrobial functionality. A pad-dry-cure process was performed to endow those functionality to the soybean protein fabrics. The treated fabrics by finishing agents have significantly improved antimicrobial and deodorization activity. However the chitosan only treated fabrics show relatively low functionality. Thus, we used the glyoxal as a crosslinking agent to increase the adhesion between the fabric and chitosan. The chitosan treated fabrics with glyoxal have high antimicrobial and deodorization activities as well as improved durability.

목적: 안과 전공의가 시행한 유리체내 주입술의 단기 안정성을 확인해보고자 한다. 대상과 방법: 2018년 1월부터 2020년 10월까지 본원에서 안과 전공의 및 망막 전문의에게 베바시주맙, 라니비주맙, 애플리버셉트 및 트리암시놀론 아세토나이드 유리체내 주입술을 처음으로 시행 받은 503명의 503안의 의무기록을 후향적으로 분석하였다. 결과: 총 503안 중 안과 전공의가 211안(전공의군), 망막 전문의가 292안(망막 전문의군)에 유리체내 주입술을 시행하였다. 두 군 간의 주사 전 임상양상의 차이는 원인 질환의 빈도를 제외하고 관찰되지 않았다. 안압상승은 전공의군에서 2안(0.95%), 망막 전문의군에서 5안(1.71%) 발생하였으나, 두 군 간의 유의한 차이는 없었다. 결막하 출혈은 전공의군에서 29안(13.74%), 망막 전문의군에서 32안(10.96%) 발생하였으나, 두 군 간의 유의한 차이는 없었다. 비감염성 안내염은 전공의군에서는 발생하지 않았고, 망막 전문의군에서 2안(0.68%) 발생하였으나, 두 군 간의 유의한 차이는 없었다. 감염성 안내염은 전공의군에서 2안(0.95%), 망막 전문의군에서 1안(0.34%) 발생하였으나, 두 군 간의 유의한 차이는 없었다. 두 군 모두에서 각막미란, 외상성 수정체 손상, 유리체출혈, 망막열공 및망막박리는 발생하지 않았다. 결론: 단기간의 안구 합병증의 발생 빈도를 평가하였을 때, 안과 전공의가 유리체내 주입술을 시행하여도 안전할 것으로 생각된다. Purpose: This study evaluated the short-term safety of resident-performed intravitreal injections. Methods: We retrospectively reviewed the medical records of 503 patients (503 eyes) treated for the first time in our hospital from January 2018 to October 2020 via intravitreal bevacizumab, ranibizumab, aflibercept, or triamcinolone acetonide injections by residents or retina specialists. In terms of short-term ophthalmic complications, patients were followed-up 1 day, 1 week, and 1 month after injection. Results: A total of 503 eyes of 503 patients were included. Intravitreal injections were given to 211 and 292 eyes by residents (the resident group) and retina specialists (the retina specialist group), respectively. There were no between-group differences in baseline characteristics except in terms of the indications for injection. Intraocular pressure elevation >5 mmHg occurred in two eyes (0.95%) in the resident group and five (1.71%) in the retina specialist group, but the difference was not statistically significant. Subconjunctival hemorrhage occurred in 29 eyes (13.74%) of the resident group and 32 eyes (10.96%) of the retina specialist group; again, the difference was not statistically significant. No case of noninfectious endophthalmitis occurred in the resident group but two (0.68%) cases occurred in the retina specialist group; again, the difference was not significant. There were two (0.95%) cases of infectious endophthalmitis in the resident group and one (0.34%) case in the retina specialist group; again, the difference was not significant. No corneal erosion, traumatic lens damage, vitreous hemorrhage, or retinal tearing or detachment were noted in either group. Conclusions: Resident-performed intravitreal injections appear to be safe.

19세기 대전 지역 음식 조리서의 국어학적 연구

배영환(Young-hwan Bae) 한국중원언어학회 2012 언어학연구 Vol.0 No.25

This study bibliographically examines and investigates the Korean linguistic characteristics found in Ueumjebang and Jusiksiui, the cookbooks transcribed in Daejeon area in the 19th century. The two documents are known as a type of cookbooks handed down for generations in the family of Jungil Dongchundang Song, and it is difficult to confirm the transcriber specifically. Considering the change of writing style in the middle of the text and the overlapping of contents, it is difficult to see them as the transcriptions by a single person but by at least a few people or through a few generations. Also, it is quite likely that Ueumjebang was transcribed before Jusiksiui considering various Korean linguistic characteristics of Ueumjebang and the fact that Jusiksiui includes contents similar to that of Ueumjebang. Particularly, Jusiksiui seems to be much influenced by Gyuhapchongseo. For Korean linguistic characteristics, these two documents show the trends of post modern Korean language and the 19th century dialect of Chungcheongnam-do. Palatalization, vowel raising, mid-vowelization, front-high vowelization, h-deletion, and so forth are found, and Ueumjebang was notated more conservatively than Jusiksiui. Auxiliary prepositions such as "cheoro" and "manchi" were used commonly and the ending, "-doe," appears in many variations such as "-doe", "-eudoe", and "eodoe." Considering lexical characteristics, various forms reflecting each linguistic phenomenon were used for each form.

1930년대 간행된 『諺文讀本』에 대한 연구

배영환(Bae, Young-hwan) 한국학중앙연구원 2015 장서각 Vol.0 No.34

이 글은 1936년 충청북도 지방과에서 간행된 『諺文讀本』의 간행 경위와 간행 목적, 그리고 책의 체재와 내용상의 특징, 표기상의 특징 등을 살펴보는 데 목적이 있다. 이 시기의 국어 교과서는 『조선어독본』이었는데, 이것과는 성격이 다른 국어 교과서가 지방에서 발행되었다는 점에서 특이하다. 『언문독본』은 전체 41장으로 구성되어 있고, 뒤쪽에 부록이 있다. 그리고 이 책을 편찬한 곳이 충청북도이고, 발행한 연대는 1936년, 그리고 발행한 사람이 일본인 岸本淸人으로 기록되어 있다. 이러한 정보 외에 이 책을 발행한 목적이라든지, 이 책을 편찬하는 데 관여한 인물에 대한 정보는 전혀 없다. 다만, 岸本淸人은 확인 결과 조선총독부의 관리로 나타났다. 그리고 이 책에 대한 편찬 경위 등은 『매일신보』에 기록되어 있는데 농촌의 계몽과 문맹 퇴치를 목적으로 간행되었고, 1933년에 최초로 펴낸 것으로 확인된다. 본문의 내용은 기존의 다른 교재와 중복되는 부분이 있지만 새로운 내용이 대부분이다. 그리고 전체적으로 정보 전달과 계몽, 교훈적인 내용으로 구성되어 있다. 그 중 ‘사대절’ 단원은 일본의 4대 기념일을 제시했다는 점에서 그 당시 상황을 말해 준다. 이 밖에 이 책은 표기법상으로 다른 교재와는 차이가 있다. 받침에는 ‘ㄱ, ㄴ, (ㄷ), ㄹ, ㅁ, ㅂ, ㅅ, ㅇ’과 겹받침에는 ㄹ-계 자음군인 ‘ㄺ, ㄻ, ㄼ’이 확인된다. ‘ㄷ’이 표기된 형태도 한 예가 나타난다. 어중 유기음 표기도 다양한데, 체언의 경우는 연철 표기가 확인되지 않는다. 그리고 ‘ㅊ,ㅋ’은 부분 중철의 양상이 일반적이고, ‘ㅌ, ㅍ’은 재음소적 표기가 일반적이다. 띄어쓰기도 나타나지만, 띄어쓰기의 단위가 일정하지 않은 특징을 보인다. 전반적으로 표기법은 정제되지 못한 양상을 보여 준다. This research aimed at investigating the publication course, publication purpose, system of the book and the characteristic of content, etc. of Eonmundokbon, which was published in the local office of Chungcheongbukdo in 1936. Korean language textbook of this period was Joseon language dokbon, however it is unusual considering that Korean language textbook that had different characteristic from this was published in the province. Eonmundokbon is composed of total 41 chapters, which has an appendix in the back. This book was compiled in Chungcheongbuk-do, in 1936, and publisher was recorded as a Japanese, 岸本淸人 (Kishimoto Kihyohito). Besides such information, there’s no information about the purpose of publishing this book and the person related to compile this book. However, as the result of investigation, 岸本淸人 was researched as an administrator of Japanese General Government. Also, the publication route of this book, etc. was recorded in Maeilsinbo, which was published for the purpose of enlightenment of the farmers and a crusade against illiteracy, which was confirmed to be published in 1934 for the first time. The content of the text has overlapping part with the existing other textbooks, nevertheless, mostly new content. Also, on the whole it was composed of information transmission, enlightenment, and moral content. Among them, ‘Sadaejeol’ unit tells the situation of that period in respect that it suggested 4 anniversaries of Japan. Besides, this book has difference from other textbooks in respect of orthography. As the syllable final alphabets, ‘ㄱ, ㄴ, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ’, and as the final consonants cluster, ㄹ-system final consonants cluster, ‘ㄺ, ㄻ, ㄼ’ are confirmed. However, one case appears with a type written with ‘ㄷ’. Aspirate writing between the words was various, in respect of substantive, consecutive alphabet writing was not checked. Spacing also appears, however there’s a characteristic that unit of spacing was not regular. On the whole, notation didn’t show a refined aspect.

전기비저항 측정에 따른 타설 시 콘크리트의 타설 불량 평가

배영환 ( Bae Young-hwan ),방진수 ( Bang Jin-su ),임홍재 ( Yim Hong-jae ) 한국구조물진단유지관리공학회 2021 한국구조물진단유지관리공학회 학술발표대회 논문집 Vol.25 No.2

콘크리트는 적정 배합 설계에도 불구하고 주변의 기후, 필요 이상의 과다 다짐, 혼화제의 첨가 등 예기치 못한 문제가 발생할 수 있다. 그러나 콘크리트의 물성을 평가하는 기존 방법들은 설계 대상 구조물이 아닌 원주공시체 등에 의한 결과이므로 대표성을 가지기는 어렵다. 또한, 콘크리트 특성 상 외부요인에 따른 내부의 물리적 거동 변화에 대한 직접적인 평가가 불가능하다. 따라서 본 연구에서는 초기 재령 콘크리트의 타설 시에 발생될 수 있는 타설 불량, 재료분리 등 충전 성능에 대한 선제적 전기비저항 비파괴 평가법을 제안하고자 한다.
