관수 개시점에 따른 복숭아 ‘천중도백도’의 과실 품질 및 생산성 변화 분석
이슬기,조정건,정재훈,이동용,한점화,장시형,류수현,김희태,강상현,이슬기 (사) 한국생물환경조절학회 2023 생물환경조절학회지 Vol.32 No.4
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.

이슬기 고려대학교 중국학연구소 2015 中國學論叢 Vol.48 No.-
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.

고객무례경험이 원무행정직원의 직무만족과 고객지향성에 미치는 영향
이슬기,한우석 한국서비스경영학회 2018 서비스경영학회지 Vol.19 No.5
The purpose of this study is to empirically test the relationships between customer incivility and job satisfaction, customer orientation. For this purpose, both literature study and empirical study was conducted. And we have selected three factors as the customer incivility, job satisfaction and customer orientation variable. The data was collected by using structured questionnaires to hospital administration employees. The proposed research model is testing 195 valid questionnaires using PASW 18.0 and AMOS 18.0. The result of this study reveal that customer incivility are negatively associated with job satisfaction and customer orientation. There was a partial mediating effect of job satisfaction between customer incivility and customer orientation. It is hoped that this will be used as basic data to raise social awareness about the working conditions of hospital administration.
