With the change of modern paradigm, industrial facilities have been transformed into idle spaces. We want to build a social platform with local members through cultural value innovation. Various value exchanges that occur on the platform bring about community activations and network effects. In addition, a circular system will be established to enhance user satisfaction, generate profits, and secure many users. Also, after renovation of idle space, Continuous maintenance, space composition for interaction, vitalization of socio-cultural values and creation of economic benefits are required. It is necessary to actively accept and reflect the characteristics of the platform when doing renovation. Therefore, the purpose of this study is to analyze and organize the methods and platform characteristics to be achieved in the renovation of idle spaces. As a research method, the generation of idle spaces is understood first, and the renovation method of idle spaces is reviewed. It also understands the theoretical concept of the platform and derives the characteristics of the spatial platform through prior study of the platform. The spatial classification is classified as public, cultural, educational, resident and commercial. Renovation methods have preservation, transformation and utilization, and platform characteristics have been derived variability, openness, mutuality, complexities, accessibility. Based on this, eight cases were analyzed by substituting the platform characteristics and methods of renovation of idle spaces by space classification. The comprehensive analysis is as follows. Accessibility and mutuality were high, but openness and complexities were low. Thus, in the renovation of idle space, it is necessary to introduce the expressive elements of variability and openness that are characteristic of the platform. And it can be supplemented by the deformation method. For idle space to create new features and values and change images, Factors that did not exist in buildings in the past and the introduction of new materials should be considered. As a result of this research, we hope that the renovation of idle spaces will be a self-sustaining space, providing cultural hubs for the region and society, as it will be consistent with local values and form a space that reflects platform characteristics.

The Pragmatic Interpretation of Linguistic Politeness

강현지 미래영어영문학회 2013 영어영문학 Vol.18 No.2

언어적 공손성은 어휘 의미론적이기 보다는 화용론 규칙의 지배를 받는다. 하지만 이런 화용론적 공손 규칙들도 한 상황에 동시에 적용될 경우 화자와 청자 간의 공손성 전달과 해석을 방해하는 면이 있다. 그 이유는 규칙들이 개별적으로는 이론적 타당성이 확고하기는 하지만 각기 다른 관점에서 공손성 속성을 기술하고 있기 때문이다. 다음으로 대화 속 공손성 이해의 주체는 화자보다는 청자가 더 중심역할을 한다. 아무리 화자가 공손성 규칙에 따라 공손성을 전달 하고자 해도 화자의 규칙을 청자가 인지 못한 경우 화자의 공손성은 전달되지 않는다. 그 예로 화자가 공손성 규칙에 따라 청자의 체면을 세워 주기위한 ‘악의 없는 거짓말’ 한다 해도 청자가 그 규칙을 똑같이 인지하고 있지 않으면 화자의 공손성은 전달되지 않는다. 이 경우 청자에게 공손성 해석의 주도권이 달려있다. 반면 언어적 중의성이 개입되면 화자는 그 중의성을 악용하여 청자에게 비 공손적 표현, 즉 풍자나 혹은 조롱이 담긴 내용마저도 중의적 해석의 미묘한 차이를 이용하여 공손성 규칙에 위배 없이 전달한다. 이 경우 앞의 상황과는 대조적으로 화자가 공손대화의 흐름에 주도권을 가지게 된다.

Understanding Jokes in English: Viewed from Incongruity and Frame-Shift

강현지 언어과학회 2013 언어과학연구 Vol.0 No.66

In verbal humors the sequence of spotting an incongruity and shifting frames in accordance is a pivotal step for getting the punch line. Quite often, however, audience overlook such a clue for detecting such incongruity and so fail to switch the frames in time. This paper aims at understanding the joke mechanism by shedding light on what triggers incongruity for frame-shift. In probing incongruity, the paper narrows down its research areas into three: non-lexical (pragmatic), lexical (semantic) and deictic (syntactic) incongruities. In dealing with the non-lexical incongruity, this paper proposes the pragmatic concept of ‘encyclopaedic knowledge' as a linguistic tool for disambiguating incongruity. In the case of lifting off lexical incongruity, this writer proses the ‘sequential storyline' as a possible expedition by which to dispel lexical incongruity. Finally the writer investigates deictic ambiguity to point out that additional syntactic knowledge plays another key role in solving syntactic ambiguity.

Purpose: We report a case of stromal keratitis in a patient with congenital hypogammaglobulinemia. Case summary: A 15-year-old boy presented with decreased visual acuity in the right eye. He had been diagnosed with congenital hypogammaglobulinemia at about 16 months of age and had received regular doses of intravenous immunoglobulin. The best-corrected visual acuity of the right eye was 0.02 and the intraocular pressure 11 mmHg. On anterior segment examination, thinning combined with stromal infiltration of the paracentral cornea was evident, but no epithelial defect was apparent. We scheduled detailed systemic examinations and laboratory investigations to rule out infectious keratitis. His serum immunoglubulin G (IgG) level was 328.9 mg/dL, thus less than that 3 months priorly (434.8 mg/dL). The lesion did not improve after prescription of topical antibiotics and steroid. The serum IgG level gradually increased to 394.4 mg/dL after immunoglobulin administration, and the corneal infiltration gradually decreased. After 5 months of treatment, the serum IgG levels ranged between 480 and 530 mg/dL; we noted no recurrence or worsening of the corneal lesion. Conclusions: We report a case of stromal keratitis in a patient with congenital hypogammaglobulinemia; we prescribed intravenous immunoglobulin. 목적: 선천저감마글로불린혈증 환아에서 사이질각막염을 경험하여 보고하고자 한다. 증례요약: 15세 남자가 우안 시력저하로 내원하였다. 환아는 생후 16개월에 선천저감마글로불린혈증을 진단받고 정기적으로 면역글로불린을 투여 받고 있었다. 우안 최대교정시력 0.02, 안압 11 mmHg였고 전안부검사상 중심부와 주변부 각막사이질의 침윤과 얇아진 소견이 관찰되었으나 상피결손은 없었다. 급성사이질각막염으로 진단하고 1% Prednisolone acetate, 5% NaCl, Levofloxacin 점안액으로 치료를 시작하였다. 전신검사상에서 혈청 immunoglubulin G (IgG) 수치가 328.9 mg/dL로 3개월 전인 434.8 mg/dL에 비해 감소되어 있었다. 안약 점안 후에도 병변의 호전은 없었으나, 면역글로불린 투여 후 IgG 수치가 394.4 mg/dL로 증가하며 각막침윤이 감소하였다. 이후 IgG 수치는 480-530 mg/dL로 유지되었고 최대교정시력은 0.15, 각막두께는 330 μm로 측정되었으며 각막병변의재발과 악화는 없었다. 결론: 선천저감마글로불린혈증 환자에서 혈청 IgG 수치가 저하되며 발생한 사이질각막염에서 면역글로불린 투여로 호전되는 소견을 관찰하여 이를 보고한다.

강현지,조용운,김병선,정지성,박종문,정인영,유웅선 대한안과학회 2019 대한안과학회지 Vol.60 No.11

목적: 유리체내 덱사메타손삽입술을 시행한 망막중심정맥폐쇄 황반부종환자에서 망막내층손상과 시력과의 관계를 알아보고자 한다. 대상과 방법: 이전에 유리체내 주입술을 시행 받지 않은 망막중심정맥폐쇄 황반부종환자 중 유리체내 덱사메타손삽입술을 시행한 22명 22안을 대상으로 후향적으로 조사하였다. 각 방문마다 스펙트럼 빛간섭단층촬영을 시행하였다. 망막내층손상의 범위와 추가적인 빛간섭단층촬영 결과는 망막중심오목을 중심으로 2,000 μm 넓이의 영역에서 평가하였다. 결과: 22안(평균 연령, 74.5 ± 8.92세) 중 21안(94.5%)에서 망막내층손상이 발견되었다. 단변량 분석에서 초기 최대교정시력은 초기 망막내층손상의 범위(p=0.005, r=-0.58)와 바깥 경계막 및 광수용체 내절의 타원 영역의 손상 범위(p=0.015, r=-0.51; p=0.011, r=-0.533)와 통계적으로 유의한 상관관계를 보였다. 최종 최대교정시력은 초기 최대교정시력(p<0.001, r=0.74)과 초기 망막내층손상의 범위(p=0.04, r=-0.35)와 통계적으로 유의한 관계를 보였다. 또한 최대교정시력의 변화는 처음과 최종 내원 시 망막내층손상의 변화량과 관련이 있었다(p=0.041, r=0.439). 결론: 망막중심정맥폐쇄 황반부종의 치료로 유리체내 덱사메타손삽입술에서 초기 망막내층손상의 범위와 최종 내원 시 망막내층손상의 변화는 시력 개선을 판단할 수 있는 유용한 지표가 될 수 있을 것이다. Purpose: To examine whether disorganization of retinal inner layers (DRILs) at baseline and after treatment was associated with visual acuity in patients with macular edema secondary to central retinal vein occlusion (CRVO) who were treated with intravitreal dexamethasone implants. Methods: A retrospective review of records of 22 patients with treatment-naive CRVO with centrally involved macular edema treated with intravitreal dexamethasone implants. Spectral domain-optical coherence tomography images were obtained during each visit. The DRIL extent and additional parameters were evaluated in a 2,000 μm-wide foveal centered area. Results: In the 22 patients (74.5 ± 8.92 years), baseline DRIL was observed in 21 eyes (94.5%). Using univariate analysis, baseline best corrected visual acuity (BCVA) was significantly associated with the extent of baseline DRIL (p = 0.005, r = -0.58), and the extent of external limiting membrane disruption and ellipsoid zone (p = 0.015, r = -0.51; p = 0.011, r = -0.533, respectively). The final BCVA was significantly correlated with the baseline BCVA (p < 0.001, r = 0.74) and extent of DRIL (p = 0.04, r = -0.35). Changes in the BCVA were correlated with changes of DRIL between baseline and the final visit (p = 0.041, r = 0.439). Conclusions: The extents of baseline DRIL and DRIL changes after treatment with intravitreal dexamethasone implants for macular edema secondary to CRVO may be useful parameter for visual acuity improvement.

Obesity is now recognized as a disease. This study revealed a novel role for pyruvate dehydrogenase kinase (PDK) in diet-induced hypertrophic obesity. Mice with global or adipose tissue-specific PDK2 deficiency were protected against diet-induced obesity. The weight of adipose tissues and the size of adipocytes were reduced. Adipocyte-specific PDK2 deficiency slightly increased insulin sensitivity in HFD-fed mice. In studies with 3T3-L1 preadipocytes, PDK2 and PDK1 expression was strongly increased during adipogenesis. Evidence was found for epigenetic induction of both PDK1 and PDK2. Gain- and loss-of-function studies with 3T3-L1 cells revealed a critical role for PDK1/2 in adipocyte differentiation and lipid accumulation. PDK1/2 induction during differentiation was also accompanied by increased expression of hypoxia-inducible factor-1α (HIF1α) and enhanced lactate production, both of which were absent in the context of PDK1/2 deficiency. Exogenous lactate supplementation increased the stability of HIF1α and promoted adipogenesis. PDK1/2 overexpression-mediated adipogenesis was abolished by HIF1α inhibition, suggesting a role for the PDK-lactate-HIF1α axis during adipogenesis. In human adipose tissue, the expression of PDK1/2 was positively correlated with that of the adipogenic marker PPARγ and inversely correlated with obesity. Similarly, PDK1/2 expression in mouse adipose tissue was decreased by chronic high-fat diet feeding. We conclude that PDK1 and 2 are novel regulators of adipogenesis that play critical roles in obesity.

금속산화물 분말의 동결건조 및 수소환원에 의한 Mo-Cu 다공체 제조

강현지,한주연,오승탁,Kang, Hyunji,Han, Ju-Yeon,Oh, Sung-Tag 한국분말재료학회 (*구 분말야금학회) 2019 한국분말재료학회지 (KPMI) Vol.26 No.1

In this study, porous Mo-5 wt% Cu with unidirectionally aligned pores is prepared by freeze drying of camphene slurry with $MoO_3-CuO$ powders. Unidirectional freezing of camphene slurry with dispersion stability is conducted at $-25^{\circ}C$, and pores in the frozen specimens are generated by sublimation of the camphene crystals. The green bodies are hydrogen-reduced at $750^{\circ}C$ and sintered at $1000^{\circ}C$ for 1 h. X-ray diffraction analysis reveals that $MoO_3-CuO$ composite powders are completely converted to a Mo-and-Cu phase without any reaction phases by hydrogen reduction. The sintered bodies with the Mo-Cu phase show large and aligned parallel pores to the camphene growth direction as well as small pores in the internal walls of large pores. The pore size and porosity decrease with increasing composite powder content from 5 to 10 vol%. The change of pore characteristics is explained by the degree of powder rearrangement in slurry and the accumulation behavior of powders in the interdendritic spaces of solidified camphene.

강현지,신동희 한국지구과학회 2021 한국지구과학회지 Vol.42 No.5

This study aims to investigate the problem recognition and clue capture processes of the observation stage in a geological field trip using abductive inquiry. To this end, eight outdoor geological programs were developed in the order of diagnostic evaluation, outdoor geological fieldwork, and review. Six middle-school students participated in these programs The geological field trip was conducted twice, followed by data provision, observation, rule generation, hypothesis generation, and final hypothesis presentation. Outdoor geological fieldwork recordings and student activity sheets were collected and analyzed qualitatively. From these data, three aspects of student observations emerged during the geological fieldwork: The characteristics of each pattern were subdivided into the geological importance of the clues, attention, type of clues, observation characteristics (attention factor), clue utilization, and clue deletion. Here, by combining these results, we propose educational applications that correspond to each aspect. 본 연구는 귀추가 적용된 야외 지질 답사에서 중학생들의 관찰을 통한 문제 인식과 단서 포착 과정을 조사했다. 이를 위해 진단 평가, 야외 지질 답사, 답사 정리 순서로 진행되는 8회에 걸친 프로그램을 개발하여 중학교 1학년 학생6명에게 적용했다. 야외 지질 답사는 2회로 자료 제공, 관찰, 규칙 생성, 가설 생성, 최종 가설 발표 순서로 진행됐다. 연구 자료로 야외 지질 답사 수업 녹음 및 녹화 자료, 학생 활동지 등이 수집되어 질적으로 분석됐다. 분석 결과, 야외지질 답사 수행에서 세 가지 관찰 양상이 나타났다. 첫째, 관찰한 후 단서로 활용한 경우, 둘째, 관찰한 후 단서로 활용하지 않은 경우, 셋째, 관찰하지 못해 단서로 활용하지 않은 경우 등이다. 각각은 단서의 지질학적 중요도, 주목도, 단서의 종류, 관찰 특징(주목도 요소), 단서 활용 내용, 단서 버림 이유 등으로 구분할 수 있다. 이러한 결과를 종합해 각양상에 해당하는 교육적 적용 방안을 모색하여 제시했다.
