본 연구는 노지 복숭아 과원에서 관수 개시점에 따른 복숭아 ‘천중도백도’의 수체 생육, 생리 반응 및 과실 품질과 생산성 변화를 분석하여 적정 관수 개시점을 구명하고자 수행하였다. 시험 재료는 전라북도 완주군에 위치한 국립원예특작과학원 내의 노지 복숭아 시험포(35°49′30.4″N, 127°01′ 33.2″E)에 재식된 7년생 ‘천중도백도’ [Prunus persica (L.) ‘Kawanakajima Hakuto’]를 사용하였으며, 2022년 6월부터9월까지 관수 개시점을 –20, –40, –60, –80kPa로 설정하였다. 주간부 단면적 증가량과 엽면적은 처리 간 통계적 유의차가 없었으나, 신초 길이와 두께는 –80kPa 및 –20kPa 처리구에서 감소하였다. 8월에 측정한 광합성률은 –60kPa(17.7 μmol·m-2·s-1), –40kPa(15.6μmol·m-2·s-1), –20kPa(14.5μmol· m-2·s-1), –80kPa(14.0μmol·m-2·s-1) 순으로 높았다. 5월과8월에 측정한 SPAD 값은 –60kPa 및 –40kPa 처리구보다–80kPa 및 –20kPa 처리구에서 낮았다. 수확기는 –20kPa 처리구가 다른 처리구와 비교하여 3일 빠르게 도달하였다. 과중은 –60kPa(379.1g), –40kPa(344.0g), –80kPa(321.0g), –20kPa(274.9g) 순으로 높았다. 경도는 –20kPa 처리구에서가장 낮았다. 가용성 고형물 함량은 –60kPa 처리구에서13.3°Bx로 가장 높았다. 상품과 비율은 –60kPa 처리구에서50.7%로 가장 높았고, –80kPa 처리구에서 23.4%로 가장 낮았다. 따라서 노지 복숭아 과원에서 관수 개시점을 –60kPa로 설정하는 것이 생산량 및 과실 품질을 향상시킬 수 있을 것으로 판단된다. This study was conducted to determine the optimal irrigation starting point by analyzing tree growth, physiological responses, fruit quality, and productivity in peach orchards. Seven-year-old ‘Kawanakajima Hakuto’ peach trees were used in an experimental field (35°49′30.4″N, 127°01′33.2″E) located within the National Institute of Horticultural and Herbal Science located in Wanju-gun, Jeollabuk-do. The irrigation starting point was set with four levels of –20, –40, –60, and –80 kPa from June to September 2022. While there were no significant differences in increase of trunk cross-section area and leaf area among treatments, shoot length and diameter decreased in the –80 kPa and –20 kPa treatments. The photosynthetic rate measured in August was highest for –60 kPa (17.7 μmol·m-2·s-1), followed by –40 kPa (15.6 μmol·m-2·s-1), –20 kPa (14.5 μmol·m-2·s-1) and –80 kPa (14.0 μmol·m-2·s-1). SPAD value measured in May and August was lower in the –80 kPa and –20 kPa treatments than in the –60 kPa and –40 kPa treatments. The harvest date reached three days earlier in the –20 kPa treatment compared to other treatments. The fruit weight was highest in the –60 kPa (379.1 g), followed by –40 kPa (344.0 g), –80 kPa (321.0 g) and –20 kPa (274.9 g). Firmness was the lowest in the –20 kPa treatment. The soluble solid content was highest in the –60 kPa treatment (13.3°Bx).The ratio of marketable fruits was highest in the –60 kPa treatment (50.7%) and lowest in the –80 kPa treatment (23.4%). In conclusion, we suggest that setting the irrigation starting point at –60 kPa could improve the fruit quality and yield in peach orchards.

We find that a lot of copula sentences in the spoken modern Chinese language environment, often exhibit no verbal ‘NP1 + NP2’ form. For example, “Wo shi shanghairen.” So, ‘NP1 + is + NP2’ and ‘NP1 + NP2’ is one structure or two structure? In this paper, this problem is to departure. In this paper, the basic ideological foundation: the sentence is consisted of Subject and Predication (Chomsky); and nominal components can not serve as the predication of a sentence. Therefore, we believe that the two structures is actually one structure, we regard the one is the verb ellipsis form than the other. Firstly, We find that There are many similarities characters between the English copula “be” and the Chinese ‘shi’, We refer to the analysis of English copula sentences as a basis for re-analysis of modern Chinese ‘shi’ copula sentence``s structure and classification. We regard Chinese copula ‘shi’ as a ‘raising verb’, the ‘Small clause’ as its complement. Moreover, we distribute the ‘Copula sentences’ into three classes, ‘entity sentences’, ‘predicational sentences’ and ‘specificaitonal sentenses’. Secondly, we reanalyses Chinese predicative DP serving as a predicate in sentence, and analyses which components play a role in the ellipsis copula sentences. Finally, summarize the limit condition of the Chinese copula ellipsis phenomena.

공공미술의 공공성에 대한 인식변화 및 도시공간 속 장르의 변화양상 고찰 - 뉴욕의 사례를 중심으로 -

이슬기 미술사학연구회 2012 美術史學報 Vol.- No.39

The term ‘public art’ was officially coined in the late 1960s. Since then,the concept has been consistently utilized by different areas under common understanding; art in public. The study has been covered rather sporadically by social scientists and urban economists. Public art has been around since the ancient times and has been extensively studied by art historians up to the modern era. yet, the question remains, in which disciplinary context public art should be studied upon?The paper is focused on followings. First, acknowledging that there has been a lack of methodical approach in literature research, it deals with John Dewey’s theory of the Public and its Problem, Hannah Arendt’s discourse on public realm and a recent study on populist public art by Cher Krause Knight. It has been inferred that the binary distinction between the public and private realm cannot explain the intricacy of current public art practices. Rather, the focus should be redirected to a third realm of transitional space where the public and the private overlap in the urban settings. The findings were reflected in the case of public art projects in New York City, especially in the form of temporary installation with support from private realm. The findings also underscore the importance of establishing a public art dialogue that encompasses art, social science, and urban studies. Each argument has its own merit yet collectively they can provide a comprehensive approach for understanding public art and its environment. Although a problem of how to appreciate and evaluate a work of public art still remains, it should be an interdisciplinary task not an independent issue. 공공미술이란 개념은 일반적으로 1960년대 후반 출현한 것으로 인식된다. 그 개념은 미술을 포함한 다양한 분야로 확장되어 일종의 합의하에 일관적으로 사용되었고 도시성장과 경제의 논리를 바탕으로 간헐적으로 연구가 진행되어 왔다. 공공미술은 도시사회의 형성과 더불어 고대에서부터 존재해왔고 근대사회 이전까지만 해도 미술의 이론에서 집중적으로 다루어져왔으나 현재는 공공미술 자체에 대한 체계적인 담론이 거의 이루어지지 않고 있다. 본 연구는 첫째, 기존 공공미술 논의에서 미흡했던 문헌연구를 통해 공공미술의 공공성에 대한 인식이 다각화, 광의화됨을 고찰하였다. 존 듀이가 논의하는 응집될 수 없는 공공의 문제, 서로에 대한 차이를 인정하고 자유롭게 소통될 수 있는 아렌트의 공론 영역의 개념을 재조명하고 나아가 공공성에 필연적으로 내재하고 있는 각 구성원의 삶과 주관적 경험의 다양성을 포퓰리스트 공공미술의 개념을 통해 확인하였다. 더불어 도시 내 공공공간의 감소 혹은 사유공간의 증가를 공공영역과 사유영역의 이분법적인 대립이 아닌 혼존의 혹은 과도적인 공간으로써 새롭게 조명하고자 하였다. 이에 따른 연구와 인식변화에 대한 고찰은 뉴욕의 사례를 통해서 공공영역과 사유영역이 공존할 수 있음을 확인하였다. 뉴욕의 사례연구는 정부지원의 공공미술의 측면과 민간지원으로 이루어지는 사유화된 공공미술의 측면으로 분리하였다. 두 측면 모두 사유영역과 밀접한 연계를 지니고 있으며 장르의 다양화와 임시설치를 위주로 진행되고 있음을 살펴보았다. 또한 이와 같은 연구를 통해 현 공공미술의 체계적 담론 형성에 있어 미술, 사회과학, 도시화 현상에 대한 융합적인 접근의 필요성 또한 보여주고자 한다. 각각의 논의는 개별적으로 공공미술의 공공성에 대한 인식변화를 다각적으로 설명하면서도 총체적으로는 공공미술을 하나의 담론으로써 새롭게 읽혀져야 한다. 공공미술을 어떻게 감상할 것인가, 어떻게 평가할 것인가는 여전히 공공미술의 담론에 남겨진 과제이며 이것은 비단 특정 학문분야의 독자적인 문제가 아닌 보다 총체적인 접근을 바탕으로 한 융합적 접근이 필요할 것이다.

Synthesis of thiazolium salts and their screening for catalytic activity

이슬기,김도중,박진균 대한화학회 2015 Bulletin of the Korean Chemical Society Vol.36 No.5

A facile synthetic method to prepare thiazolium-based ionic liquids in high yield was developed. The direct alkylation of thiazole was performed using a trialkyl orthoester as both the alkyl donor and the solvent. The synthesized thiazolium salts were subsequently screened for their ability to catalyze the benzoin condensation reaction. Of the salts that were tested, 3-butyl,4,5-dimethyl thiazolium salt, was found to be the best catalyst.

Zn(II) Production via a Pulsed Laser Ablation in Water: A Formation Mechanism of Zn and ZnO Nanoparticles

이슬기,안아름,최명룡 대한화학회 2015 Bulletin of the Korean Chemical Society Vol.36 No.3

Zn and ZnO nanoparticles were produced by a pulsed Nd:YAG laser ablation method in the absence of any surfactants and/or catalysts in deionized (DI) water via pulsed laser ablation in liquid (PLAL). In this paper, we present direct evidence for the production of Zn(II) ions induced from the plasma plume during the process of PLAL for the first time. Investigation of the absorption and emission spectra of zinc tetra(p-sulfonatophenyl)porphyrin (ZnTSPP) formed via the laser ablation on a Zn metal plate in TSPP solution showed a significant fluorescence quenching of ZnTSPP. This fluorescence quenching of ZnTSPP was further investigated with an aid of theoretical calculations. Based on these experimental and theoretical results, a plausible mechanism for the production of Zn and ZnO nanoparticles is proposed.
