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.

Objectives The objective of this study was to examine the and gender difference between met¬abolic syndrome and clinical psychiatric characteristics. Methods This study was conducted in local habitants who visited one community health ser¬vice from July to August 2014. 318 local habitants who have not been diagnosed with psychiat¬ric disorders were evaluated using Center for Epidemiological Studies-Depression Scale (CES-D), Reynold Suicidal Ideation Questionnaire (SIQ, Reynolds), Rosenberg Self-Esteem Scale (SES), Ko¬rean version of WHO Quality of Life Scale-Abbreviated Version (WHOQOL-BREF), and EuroQol-5 Dimension (EQ-5D). Differences in demographic characteristics of both gender were analyzed. Results In women, the group with metabolic syndrome showed significantly lower alcohol drinking frequency (p<0.001), educational level (p<0.001) compared to the group without syn¬drome. Women with metabolic syndrome had lower scores for physical health (p=0.002), envi¬ronment (p=0.007) on WHOQOL-BREF than those without the syndrome. However, CES-D, EQ-5D, SIQ, Reynolds, and SES show no differences. Among men, no difference was observed in all scales. In addition, in women, logistic regression analysis showed that after adjusting for con¬founders, metabolic syndrome group had lower score for physical health (p=0.009), environment (p=0.042) on WHOQOL-BREF than the group without syndrome. Conclusion Our study showed an association of metabolic syndrome with poor physical health, environment in women.

Online User Comments as an Agenda-Setter? An Experimental Test of the Impact of Uncivil Comments on Issue Salience

이슬기,권영성 부산울산경남언론학회 2019 지역과 커뮤니케이션 Vol.23 No.4

Online user comments which offer lay citizens’ views, feelings, and experience on news issues can help readers perceive a news issue as psychologically closer and more personally relevant, thus more important. At the same time, uncivil expressions are becoming increasingly common in user comments, raising the possibility that the potential impact of user comments may be limited. Using an online experiment, this study examines whether (a) incivility in user comments undermines how people perceive the importance of news issues and (b) a lack of empathy mediates this process. The results suggest that incivility in user comments (vs. civil comments) decreased the empathy felt toward commenters and subsequently lowered the perceived salience of a news issue. Moreover, the negative impact of incivility was more pronounced among participants who had less frequent exposure to online news and news-related user comments, suggesting that people may be desensitized to online incivility as they become more familiar with online information.

Learning before and during the COVID-19 outbreak: a comparative analysis of crisis learning in South Korea and the US

이슬기,여정원,나종민 한국행정학회 2020 International Review of Public Administration Vol.25 No.4

Learning is imperative in government responses to crises like the COVID-19 pandemic. This study examines the South Korean and United States governments’ responses to COVID-19 from a comparative perspective. The analysis focuses on crisis learning conducted before and during the COVID-19 outbreak, using the conceptual categories of intercrisis/intracrisis learning and single-/doubleloop learning. The findings suggest that double-loop, intercrisis learning allows for more effective crisis management by (re)developing a common operating framework. The efficacy of learning is enhanced when double-loop learning is followed by single-loop learning that embeds new structures and operational procedures. The findings also suggest that intercrisis learning facilitates intracrisis learning and that political support is critical for inducing crisis learning. The paper concludes with theoretical and practical implications for crisis learning.

기술위험에 대한 인식이 스마트시티의 정책수용성에 미치는 영향에 관한 연구 : 지방정부 신뢰의 조절효과를 중심으로

이슬기,이혁규 단국대학교 융합사회연구소 2023 공공정책과 국정관리 Vol.17 No.2

The purpose of this study is to investigate the effects of technology risk on policy acceptance of smart city policies aimed at addressing various urban problems through ICTs. In addition, authors examined the role of trust in local government moderating the effects of technology risk on the policy acceptance. The research hypotheses were tested using survey data conducted in 2022 based on individual perceptions. The findings can be summarized as follows: First, among the risk factors, only the economic risk had a negative effect on policy acceptance. Second, we identified the positive influence of trust in local government on policy acceptance of smart city policies. When not considering the interaction effect, trust in local government had a positive effect on policy acceptance. In the model that considered the interaction effect, respondents who perceived high levels of trust in local government had a lower perception of the negative impact of economic risk perception on policy acceptance. This suggests that local governments should effectively manage technology risks associated with smart cities. Also, the study highlights the importance of trust in local government when dealing with technology risks properly. 본 연구는 ICT에 기반해 여러 도시문제를 다루는 스마트시티 정책을 대상으로, 정책수용성에영향을 미치는 기술위험의 영향을 파악했다. 아울러 기술위험의 부정적 영향을 조절하는 지방정부 신뢰도 함께 다루었다. 2022년 수행된 설문조사 결과를 통해 응답자의 인식에 기초하여주요 연구가설을 검증하기 위한 분석을 수행했다. 분석결과는 다음과 같이 요약할 수 있다. 첫째, 위험 요인 중 경제적 위험 변수만이 정책수용성에 부정적인 영향을 미치는 것으로 나타났다. 둘째, 스마트시티 정책수용성에 대한 지방정부 신뢰의 긍정적 영향을 확인했다. 상호작용을고려하지 않았을 때, 지방정부 신뢰는 정책수용성을 높이는 데 긍정적이었다. 상호작용을 고려한 모형에서 지방정부 신뢰를 높게 인식하는 응답자들은 경제적 위험 인식이 정책수용성에 미치는 부정적 영향을 낮게 인식했다. 본 연구는 스마트시티의 정착과 확대를 위해 지방정부가스마트시티의 위험요인을 관리해야 한다는 점을 시사하며, 이 과정에서 지방정부가 주민들에게신뢰받을 수 있어야 기술위험을 효과적으로 완화할 수 있다는 점을 보여준다.

경계선 성격특성과 타인에 대한 공격성의 관계: 수치심 경향성과 특성분노의 순차매개효과

이슬기,장혜인 한국건강심리학회 2024 한국심리학회지 건강 Vol.29 No.1

경계선 성격특성을 가진 이들에게서 공격성이 나타나는 주된 기제로 정서조절곤란이 제안되어 왔다. 그러나 정서조절곤란은 상당히 복잡한 개념이며 각 증상의 효율적인 개입을 위해선 이를 세분화하여 살펴볼 필요가 있다. 이에 본 연구에서는 경계선 성격특성을 가진 이들이 공격성을 나타내는 맥락에서 특히 조절을 어려워하는 수치심과 분노에 주목하였다. 구체적으로 경계선 성격특성과 타인에 대한 공격성 간 관계를 수치심 경향성과 특성분노가 순차적으로 매개하는 모형을 검증하였다. 연구참가자는 여자대학생 273명이며, 이들을 대상으로 자기보고식 설문지를 사용해 경계선 성격특성, 수치심 경향성, 특성분노, 공격성을 측정하였다. 분석결과, 경계선 성격특성은 타인에 대한 공격성을 정적으로 유의하게 예측하였으며, 경계선 성격특성과 타인에 대한 공격성 간 관계를 특성분노가 완전매개하였다. 예상과 달리, 경계선 성격특성과 타인에 대한 공격성 간 관계에서 수치심 경향성과 특성분노의 순차매개효과는 유의하지 않았다. 본 연구는 경계선 성격특성이 공격성으로 이어지는 여러 경로를 통합적으로 확인하였으며, 연구결과를 바탕으로 본 연구의 한계 및 의의에 대해 논의하였다. It has been suggested that individuals with borderline personality features are aggressive toward others because of their difficulty in emotion regulation. However, emotion dysregulation is a highly complex concept and needs to be specified. Therefore the current study considered dysregulation in shame and anger and their interplay which are especially prominent when individuals with borderline personality features are aggressive. Specifically, it was hypothesized that shame-proneness and trait anger would sequentially mediate the relationship between borderline personality features and aggression toward others. A total of 273 female undergraduates completed a series of self-report questionnaires assessing borderline personality features, shame-proneness, trait anger, and aggression toward others. The results indicated that individuals with more borderline personality features are more aggressive toward other. Trait anger completely mediated the relationship between borderline personality features and aggression toward others. Inconsistent with the hypothesis, shame-proneness and trait anger were not significant sequential mediators between borderline personality features and aggression toward others. Based on these results, theoretical and practical implications as well as the limitations of the study were discussed.
