윤희정,윤희정,정수영,신현탁 한국경관학회 2025 한국경관학회지 Vol.17 No.2

본 연구는 국내 수목원⋅식물원의 수요자들을 대상으로 방문행태 및 잠재방문수요에 대한 후속 진단을 목적으로 한다. 이를 위해 본 연구는 1차 연구와 동일한 조사설계를 통해 서울, 경기, 강원, 충청, 경상, 전라의 6개 지역에서 설문조사를 진행하였으며, 708부의 유효 응답자수를 확보하였다. 주요 연구결과, 수목원⋅식물원의 방문비율 및 재방문율, 정규교육⋅해설프로그램 참여비율은 다소 낮은 것으로 확인되었으나, 주변지역 방문비율은 높게 나타났다. 주요 방문동기로는여가생활 및 가족생활, 지인들과의 친목, 건강관련 요인으로 나타났다. 방문경험이 있는 경우, 만족도와 휴식 및 힐링효과, 행복감 항목에서 긍정적 효과가 확인되었다. 반면 주요 미방문 이유로는 수목원⋅식물원의 상대적으로 낮은 선호도 및 자체 매력성, 수목원⋅식물원 자원성의 근간이되는 자연생태 자원에 대한 낮은 관심도가 주요 요인으로 분석되었다. 수목원⋅식물원의 잠재방문수요에 대한 분석결과, 방문의도가 매우 높게 나타났으며 걷기 관련 공간과 프로그램에 대한선호도가 높게 나타났다. 이상의 연구결과는 주요 계획요소 도출, 정책 우선순위 결정, 공간⋅활동⋅해설프로그램 개발전략 수립 등에 유용하게 활용될 수 있을 것이다. The purpose of this study is to make a follow-up diagnosis the visitors’ behaviors and the potential visit demands of domestic arboreta or botanical gardens. For this purpose, the questionnaire survey conducts to the valid 708 the public nationwide in the 6 regions; Seoul, Kyeonggi, Kangwon, Chungcheong, Kyeongsang and Jeonla province, through the same survey design as the first study. The key results about visitors’ behaviors show that visit and revisit ratio, participation ratio of regular activity and interpretation program were relatively low, but the rate of visits to the surrounding areas was high. And the main visit motivations were leisure, family life, friendship and health. Most respondents had visit experiences responded the visitation of arboreta or botanical gardens were helpful to improve their overall satisfaction, healing, and happiness. On the other hand, the main reasons for not visiting were the relative low preferences and attractiveness of arboretum and botanical gardens, and the low interest in natural ecological resources. In addition, the key results about potential visit demands show that the visit intention and preferred space and program related to walking were high. The above research results can be usefully used to derive major planning elements, determine policy priorities, and establish strategies for developing space, activities, and commentary programs.

A Study on Flipped Learning Based Presentation Activities for EFL College Students’ Speaking Classes

윤희정,홍연란,장군자 국제문화기술진흥원 2025 International Journal of Advanced Culture Technolo Vol.13 No.1

This study investigates the changes in English-speaking abilities and their perceptions of communication competence among EFL college students through presentation activities based on flipped learning. Forty-four students participated in these activities over 15 weeks. The participants engaged in pre-learning by watching pre-recorded video lectures on course content and completed tasks through interactions in groups during class sessions. They then recorded video rehearsals of their presentations, submitted them to the instructor for feedback, and delivered their final presentations to the entire class. The results showed that the participants’ English-speaking abilities improved, with the most significant gains in fluency, followed by complexity and accuracy. Additionally, their perceptions of communication competence also improved. Scores increased across all subcategories of communication competence, including active listening and understanding, understanding subject, mutual understanding, consideration, and question-and-answer skills. Notably, the greatest improvement was seen in consideration, followed by understanding subject. These findings suggest that flipped learning-based presentation activities are effective in enhancing English-speaking abilities and positively influence students’ perceptions of their communication competence.

Abstract – The composition of minerals and anions in six types of decoction water (S1 to S6) were analyzed by inductively coupled plasma-atomic emission spectomerty (ICP-AES) and inductively coupled plasma-mass spectromerty (ICP-MS), respectively. Extraction efficiency of active compound of Magnoliae Flos depending on decoction water was determined by analyzing seven major peaks using HPLC and LC-MS. In results, S5 contained highest Ca, Mg and SO4 content and S4 showed the highest Cl and NO3 content than other waters. Using multiple factor analysis, it was proved that the variation of the area for peak1 and peak7 of Magnoliae Flos extract related to K, Si and Na, and peak5 linked to SO4, Cl and NO3. Considering peak5 which is highly variable depending on the type of decoction water, the area of peak5 decocted with S4, S5 and S6 were higher than those decocted with S1, S2 and S3. In conclusion, the content of compounds in Magnoliae Flos extracts was different depending on decoction water, indicating that decoction water affected the extraction efficiency and the bioactivity of Magnoliae Flos extract.

Accessory Gene Regulator Group Polymorphisms in Methicillin-Resistant Staphylococcus aureus: An Association with Clinical Significance

윤희정,최준용,이경원,용동은,김준명,송영구 연세대학교의과대학 2007 Yonsei medical journal Vol.48 No.2

Purpose: Virulent gene expression in Staphylococcus aureus is controlled by regulators such as the accessory gene regulator (agr). Strains can be divided into four major agr groups (agr I-IV) on the basis of agrD and agrC polymorphisms. The purpose of this study was to define the proportion of agr I, II, and III polymorphisms and to compare the clinical characteristics between group I and non-group I polymorphisms of methicillin-resistant Staphylococcus aureus (MRSA) strains in a Korean tertiary care teaching hospital. Materials and Methods: A total of 158 clinical isolates were evaluated by RFLPs (restriction fragment length polymorphisms). Results: The mean age of the patients was 50.2±21.9 years old. There were 74 (49.3%), 66 (44.0%), 10 (6.7%), 7 (4.4%), and 1 (0.6%) strains in agr group I, II, III, I+II, and I+III polymorphisms, respectively. Only ear infections were a statistically significant clinical parameter according to univariate (p=0.001) and multivariate analysis (OR, 4.721 (1.273-17.508), p=0.020). Conclusion: This study suggests that agr group I is the most prevalent in Korea, and ear infections are correlated with the group I polymorphism, which is a different clinical trend from western countries. It can also be inferred that community-acquired MRSA correlates with agr group I.

Selective Effects of an AI-Based Speaking Tool on Korean EFL University Students’ Speaking Proficiency and Self-Efficacy

윤희정 대한영어영문학회 2026 영어영문학연구 Vol.52 No.2

This study examined the selective effects of an AI-based speaking tool on Korean EFL university students’ speaking proficiency and self-efficacy using a quasi-experimental mixed-methods design. Eighty-one intermediate-level learners participated in a 10-week intervention (experimental group: n = 41; control group: n = 40). The experimental group used Speak, a mobile application integrating automatic speech recognition (ASR) and AI-mediated speaking interaction, while the control group completed workbook-based speaking preparation. Speaking proficiency was assessed through task-based speaking tests measuring fluency, grammatical accuracy, lexical complexity, and pronunciation, while self-efficacy was measured using an adapted 5-point Likert-scale questionnaire. Reflective journals and semi-structured interviews were also analyzed to explain learners’ perceptions and the divergence between fluency gains and non-significant affective outcomes. Quantitative results showed significant improvement only in fluency, with no significant gains in grammatical accuracy, lexical complexity, pronunciation, or self-efficacy. Qualitative findings indicated that repeated speaking practice and reduced anxiety supported fluency development, whereas limited metalinguistic feedback and reduced authenticity of interaction constrained broader linguistic and affective gains. The findings suggest that AI-based speaking tools are effective for enhancing fluency through repeated oral rehearsal but provide limited support for interaction-dependent speaking development and efficacy construction. The study highlights the importance of integrating AI-mediated speaking practice with teacher feedback and communicative interaction.
