목적: 진행하는 원발성 원추각막 및 굴절수술 후 각막확장증 환자에서 바이브 엑스 라피드 용액을 이용한 각막콜라겐 가속 교차결합술 후 효용성과 안전성을 알아보았다. 대상과 방법: 2015년 2월부터 2015년 10월까지 진행성의 원발성 원추각막 및 굴절수술 후 각막확장증을 진단 받은 30명 45안을 대상으로 바이브 엑스 라피드 용액을 이용한 각막콜라겐 가속 교차결합술 시행술 전, 술 후1개월, 3개월, 6개월에 시력검사 및 굴절검사, 각막곡률을 측정하였고, 각막두께, 각막내피세포수의 변화를 분석하였다. 결과: 최대교정시력은 술 전 logMAR 0.51 ± 0.23에서 수술 6개월 후 logMAR 0.51 ± 0.26으로 변화가 없었고, 자동각막굴절측정기 CT-80 (Topcon, Tokyo, Japan) 최대 각막곡률, 전안부 촬영기(Oculus, Pentacam, Wetzler, Germany) 측정 최대 각막곡률과 각막지형도(OrbscanII, Bausch & Lomb, Salt Lake City, UT, USA) 측정 최대 각막곡률은 술 전 각각 49.11 ± 4.5D, 48.37 ± 3.31D, 48.98 ± 4.88D에서 술 후 6개월 각각 49.29 ± 4.34D, 46.99 ± 3.63D, 47.01 ± 3.62D로 전안부 촬영기와 각막지형도 측정값에서 통계적으로 유의하게 감소하였다(p〈0.05). 자동각막굴절기로 측정한 구면값, 난시값, 구면렌즈대응치 술 전 값과 수술 6개월 후 값은 각각 -4.85 ± 3.86, -3.96 ± 2.52, -6.86 ± 4.25에서 -4.98 ± 3.68, -3.98 ± .253, -6.9 ± 4.15로 큰 변화가 없었으나 유의한 의미를 갖지 않았다. 전안부 촬영기(Oculus, Pentacam, Wetzler, Germany) 측정 각막두께와 각막지형도(OrbscanII, Bausch & Lomb) 측정각막두께의 술 전 값과 수술 6개월 후 값은 각각 485 ± 26.27, 479.24 ± 27.89에서 471.64 ± 27.12, 472.52 ± 25.36으로 전안부 촬영기에서 유의한 변화가 있었다. 각막내피 세포수는 각막공초 점현미경(Confocal microscopy, ConfoScan 4, Nidek, Inc., Freemont, CA, USA)을 이용하여 측정하였고, 술 전 2,857 ± 390.49/mm2에서 술 후 6개월째, 2,639.21 ± 249.92/mm2로 유의한 변화가 있었으나, 그 외 유의한 합병증은 관찰되지 않았다. 결론: 각막콜라겐 가속 교차결합술은, 진행성 원추각막 및 굴절수술 후 각막확장증 진행을 억제하는 치료방법이며, 내피세포의 변화에 영향을 미칠 가능성이 있으므로 장기 관찰이 요구된다. 〈대한안과학회지 2016;57(11):1714-1722〉 Purpose: To report the clinical efficacy and safety of progressive keratoconic eyes in Korean patients treated with accelerated corneal cross-linking. Methods: This retrospective study focused on progressive keratoconic eyes in Korean patients that underwent accelerated corneal cross-linking from February 2015 to October 2015. Keratoconus was diagnosed in 45 eyes in 30 patients. After accelerated corneal cross-linking with VibeX rapid solution, best corrected visual acuity, maximum keratometry, mean keratometry, corneal thickness, corneal astigmatism, and endothelial cell count were measured at the preoperative visit and post operation 1 week, 1 month, 3 months, and 6 months. Results: Best corrected visual acuity (log MAR) was 0.51 ± 0.23 at pre operation and 0.51 ± 0.26 at post operation 6 months, showing no improvement. The maximum keratometry measured with Auto K, Pentacam, and Orbscan II at pre operation was 49.11 ± 4.5 D, 48.37 ± 3.31 D, and 48.98 ± 4.88 D and changed to 49.29 ± 4.34 D, 46.99 ± 3.63 D, and 47.01 ± 3.62 D postoperatively, respectively. Only Pentacam and Orbscan II measurements showed a statistically significant decrease (p 〈 0.05). Corneal thickness (at the thinnest area) was measured with Pentacam and Orbscan II; pre-operative and post-operative 6 month data showed changes from 485 ± 26.27 and 479.24 ± 27.89 to 471.64 ± 27.12 and 472.52 ± 25.36, respectively. Only the Pentacam method resulted in a statistically significant decrease. Endothelial cell count was measured with confocal microscopy and showed a statistically significant difference between pre-operative 2,857 ± 390.49/mm2 and post-operative 6 month 2,639.21 ± 249.92/mm2. Conclusions: This 6-month follow-up study of Korean keratoconus patients who underwent accelerated corneal cross-linking indicates that the method is effective in stabilizing the progression of keratoconus, according to maximum keratometry change. With regard to endothelial cell count change, further long-term evaluation is required. Other than endothelial cell count change, this procedure is expected to show long-term safety comparable to that of conventional corneal cross-linking. J Korean Ophthalmol Soc 2016;57(11):1714-1722

산에 민감한 작용기를 갖는 tert-butyl methacrylate (tBMA)와 산 증식 기능을 갖는 1-hydroxy-4-p-styrenesulfonyloxy cyclohexane (HSC) 또는 1-p-styrenesulfonyloxy-4-tosyloxy cyclohexane (STC)의 공중합체를 새로운 고분자 산 증식형 포토레지스트로 합성하였다. Poly(HSC-co-tBMA) film과 poly(STC-co-tBMA) film의 열적 안정성은 레지스트 공정 온도에 충분히 안정한 열적 안정성을 나타내었다. 광감도 특성은 poly(HSC-co-tBMA) film은 ptBMA homopolymer에 비교하여 약 4배 정도 떨어지고, poly(STC-co-tBMA) film homopolymer에 비해 약 1.3배 정도 우수함을 확인하였다. 고분자에 도입한 산 증식 기능을 갖는 그룹의 구조에 따라 광감도 증진 효과가 다르게 나타남을 확인하였다. Acid-amplifying copolymers are synthesized by the copolymerization of tert-butyl methacrylate(tBNA) with acid sensitive functional group and 1-hydroxy-4-p-styrene-sulfonyloxy cyclobexane(HSC) or 1 p-styrene-sulfonylosy-4-tosyloxy cyclohezane(STC) with acid amplifying group as novel polymeric acid-amplifying photoresists. Poly(HSC co-rBNA ; film and poly(STC-co-tBNA) film showed reasonable thermal stability for resist processing temperature. Poly(HSC-co-tBNA) film shows 4 times lower photosensitivity and poly(STC-co-tBNA) film exhibits 1,3 times higher photosensitivity compared with ptBMA homopolymer. The attachment of acid-amplifying units to polymer backbones could provide a novel way to enhance the photosensivity of acid-sensitive polymers depending on the structure of acid-amplifying units

홍경일 ( Hong Gyeong Il ),이은주 ( Lee Eun Ju ),임권택 ( Im Gwon Taeg ),정용석 ( Jeong Yong Seog ),정연태 ( Jeong Yeon Tae ) 한국공업화학회 2003 공업화학 Vol.14 No.5

본 연구에서는 1-hydroxy-4-p-styrenesulfonyloxy cyclohexane (1), 1, 4-di-p-styrene-sulfonyloxy cyclohexane (2), 그리고 1-p-styrenesul-fonyloxy-4-tosyloxy cyclohexane (3)을 산 중식제로 합성하고 그 성능을 평가하였다. 이러한 산 중식제들(1~3)은 레지스트 공정온도에 대하여 충분한 열적 안정성을 나타내었다. 또한 산 중식제를 사용한 경우에 광산 발생제만 사용한 poly(tert-butyl methacrylate) 필름에 비교하여 2배에서 5배 정도의 감도 증진이 일어나 광화상 제조에 효과적으로 응용할 수 있음을 확인하였다. In this research, we synthesized and evaluated 1-hydroxy-4-p-styrensulfonyloxy cyclohexane. 1,4-di-p-stryrenesulfonyloxy cyclohexane, and 1-p-styrensulfonyloxy-4-tosyloxy cyclohexane as novel acid amplifiers. These acid amplifiers showed reasonable thermal stability for resist processing temperature. As estimated by the sensitivity curve, all the acid amplifiers were 2-5 times more sensitive than poly(tert-butyl methacrylate) film in the presence of a photoacid generator; and therefore, these can provided practical applicability in photoimaging.

홍경의(Hong Kyungeui),정효지(Joung Hyojee) 韓國營養學會 2009 Journal of Nutrition and Health Vol.42 No.3

본 연구의 결과를 요약하면 다음과 같다. 1) 건강식당사업에 대한 외식경영자의 인식조사에서, 건강식당에 대한 개념은 신선한 식자재 사용 (63.5%), 비흡연구역 설정 (15.9%), 표준조리법에 따라 조리하는 식당 (11.0%)과 영양이나 건강 정보표시를 하는 식당 (9.6%)으로 인식하고 있어 건강식당사업의 주요 활동이 건강한 음식을 소비자들에게 제공하면서 그 제공하는 음식에 대한 영양 및 건강에 대한 정보도 함께 제공해야 하는 것이라는 인식은 부족한 것으로 나타났다. 필요한 외부의 도움은 영양분석(30.8%), 건강한 음식에 대한 정보 (25.3%), 건강관리 정보 (18.6%), 건강메뉴를 위한 조리기술 (14.3%)로 나타났고, 건강식당사업 참여시 우려사항은 음식 맛의 변화 (57.9%), 판매저하 (13.8%), 조리 어려움 (9.7%)으로 나타났다. 표시를 원하는 영양정보는 지질 (32.4%), 열량 (23.5%), 나트륨 (20.0%), 섬유소 (9.0%) 순으로 나타났고, 건강정보는 비만 (44.2%), 당뇨 (19.3%), 심혈관질환 (18.6%), 암(13.8%), 간질환 (4.1%) 순으로 나타났다. 2) 외식경영자의 건강식당사업 참여의지 분석에서 50.3%가 참여하겠다고 응답하였고, 참여의지에 영향을 미치는 요인은 현재업종 운영기간, 음식의 질 고려정도와 영양이나 건강 정보표시 중요성 인지도로 나타났다. 이러한 본 연구 분석을 바탕으로 건강식당사업을 계획할 때 고려해야 할 활동을 제안해 보면 다음과 같다. 첫째, 건강식당사업에 참여하겠다는 응답자가 50% 정도이므로 외식경영자의 참여의지를 높이기 위한 사업이 필요하다. 둘째, 외식경영자가 건강식당사업 참여에 필요한 기술적 지원체계를 구축하고 궁극적으로 경영자와 소비자 모두에게 도움이 되는 방안을 마련해야 한다. 셋째, 참여의지에 영향을 미치는 요인은 현재업종 운영기간, 음식의 질 고려정도와 영양이나 건강 정보표시 중요성 인지도로 나타났으므로 이러한 요인을 고려한 전략적 접근 계획이 요구된다. This study examined the restaurateur’s willingness to participate in the healthy restaurant program. Using a structured self-administered questionnaire, data on subjects’ personal, business and management characteristics, willingness to participate in the healthy restaurant program and the perception of healthy restaurant program were collected from 145 restaurateurs in Seoul. Descriptive statistics, chi-square tests, and logistic regression were used in the analysis. Half of respondents (50.3%) were willing to participate in the healthy restaurant program. Years of business (OR = 2.584, 95% CI = 1.049-6.369), consideration of food quality (OR = 0.321, 95% CI = 0.147-0.702), and awareness of importance of nutrition or health information (OR = 2.416, 95% CI = 1.082-5.391) were significant indicators for restaurateur’s willingness to participate in the healthy restaurant program. Hence, strategic activities to inform the benefit of healthy restaurant program for both restaurateurs and consumers are necessary.

This paper aims to analyze the polysemous meanings of cuisine verbs which have not been fully reflected in Korean dictionaries. Korean cuisine verbs such as kkeulh-ida, gubda, jjida, jijida, bokk-da require an obligatory argument ``N1-eul`` in common. Further, they may take ``N2-ro`` and ``N3-e`` as an optional adjunct, and it varies with each cuisine verb on the context. ``N2-ro`` represents cooking ingredients, and ``N3-e`` represents cooking utensils. In this respect, we first presented the possible sentential types that each cuisine verb takes. Second, we listed the noun words presented on the ``N1``, ``N2`` and ``N3``. Third, we examined the relation between each cuisine verb and its nominal argument, and then analyzed the polysemous meanings of the five cuisine verbs based on the result. This study of polysemous meaning on essential cuisine verbs in Korean is valuable because this study result can be served as elementary data for a future contrastive study and the translation of cuisine verbs; furthermore, it will be beneficial for L2 leaners of Korean, especially for married female immigrants.

한국어 복합종결어미 연구 - ‘-다니까’, ‘-다면서’, ‘-다고’를 중심으로 -

홍경임 ( Hong Gyeong Im ) 문창어문학회 2018 문창어문논집 Vol.55 No.-

The purpose of this study is to investigate complex final endings more than one morpeme. We looked at what the complex final endings combine with other elements to form a meaning to perform its finalizing function and what type of use is preferred. The subjects of the study were ‘-danikka’, ‘-damyeonseo’, ‘-dago’. Since these complex term endings appear in many dialogue forms, they are necessary elements in the communication of actual language users. In Chapter 2, the two or more complex types were used as an important criterion to sort out the complex final endings by setting the criteria for determining the formal, semantic and the semantic standard. The grammatical basis of formal, semantic and semantic standards was based on ‘Korean grammar’. In Chapter 3, we have studied various semantics of the complex final endings ‘-danikka’, ‘-damyeonseo’, ‘-dago’ based on the criteria established in Chapter 2. It was discussed that context setting is very important in semantic analysis, and more accurate semantic analysis is possible when given the setting of this situation, because multiple meanings are represented in one form dependign on the feelings of the speaker. The data in the semantic analysis were used by revising ‘My ID is Gangnam Beauty (2018)’ for the study. In Chapter 4, we tried to examine the grammatical characteristics through the sentence types used in the complex final endings ‘-danikka’, ‘-damyeonseo’, ‘-dago’. The sentence type of complex final endings is a descriptive sentence, an interrogative sentence, an imperative sentence, a suggesting sentence, which is based on the type endings of the neutralization, and most of the sentences are a descriptive sentence, an interrogative sentence. In particular, predicate endings appeared formally rhetorical questions, contextually interrogative endings to existing interrogative ending, which is combined with the latter. In the case of predicate endings based on the neutralization, it was found that various interrogative sentences such as rhetorical questions and interrogative endings were realized using interrogations. In the syntactic processing of complex term endings ‘-danikka’, ‘-damyeonseo’, ‘-dago’ are two ways either ‘single form’ or ‘compound form’, Respectively. As a result, the complex final endings ‘-danikka’, ‘-damyeonseo’, ‘-dago’ is an emphasis on emphasizing the sentence more strongly by combining the ending sentences with the ending sentences. In chapter 5, we summarize all the contents of the research and conclude the present study by suggesting the future challenges of the limitations of the study.
