정나라,양지인 전북대학교 부설 휴양및경관계획연구소 2022 휴양및경관연구 (J East Asian Landscape Studies) Vol.16 No.2

This study identified the perceptions of 221 urban residents of indoor plants as components of a healing garden according to their experience in managing indoor plants. The experience of managing indoor plants was higher with women and older people, and the residents of detached houses and apartment houses were higher. There were differences in the experience of managing plants according to gender, age, and housing type. Among the functions of indoor plants, environmental improvement and psychological stability were highly important, and there were differences according to demographic characteristics. Females, 40s, detached house, and apartment dwellers recognized that it was important to use plants from a psychological point of view, and men, 20s, 30s, and 50s from a physical point of view. The more experience in plant management, the more necessary it is. Functions such as spatial decoration, temperature and humidity control, and emotional stability were factors that affect plant needs. The experience of managing plants had a positive effect on importance and necessity in emotional and psychological aspects. Therefore, the experience of various plants can be a factor that can improve the healing effect of plants. In particular, there is a difference in cognitive information about plants and perception by experience, so when using plants as a healing garden element, it is required to use plants that can improve health promotion effects through plants. 본 연구는 치유정원 구성요소로서 실내식물에 대한 221명 도시민의 인식을 실내식물 관리경험에 의해 비교하였다. 실내식물을 관리한 경험은 여성과 연령이 높을수록 높았으며, 단독주택과 공동주택 거주자가 높았다. 성별, 연령대, 주거유형에 따라 식물 관리 경험에는 차이가 있었다. 실내식물의 기능 중 환경 개선과 심리적 안정 등의 중요도가 높았으며, 인구통계학적 특성에 따라 차이가 있었다. 여성, 40대, 단독주택, 아파트 거주민은 심리적 측면에서, 남성, 20대, 30대, 50대는 물리적 측면에서 식물을 활용하는 것이 중요하다고 인식하고 있었다. 식물을 관리한 경험이 있으면 분위기 조절, 정서 안정 등 심리적 측면의 중요도가 높은 반면, 관리경험이 없으면 물리적 환경 구성 측면의 중요도가 높았다. 식물 관리경험이 있을수록 식물의 필요도가 높으며, 공간장식, 온습도 조절, 정서 안정 등의 기능은 식물의 필요도에 영향을 미치는 요인이 된다. 식물을 관리한 경험은 정서적, 심리적 측면에서 중요도와 필요도에 긍정적 영향을 준다. 따라서 다양한 식물에 대한 경험은 식물의 치유효과를 향상시킬 수 있는 요인이 될 수 있다. 식물에 대한 인지적 정보와 체험에 의한 지각에는 차이가 있으므로 치유정원 요소로서 식물을 활용하고자 할 때에는 식물을 통해 건강증진효과를 높일 수 있는 식물의 활용이 요구된다.

정나라,한승원,김재순,김우영,이형석 (사)한국교육녹색환경연구원 2024 교육·녹색환경연구 Vol.23 No.3

본 연구는 초등학교의 그린학교 조성 방향을 설정하기 위하여 실내공간에 도입된 식물의 현황과 관리 특성을 분석하였다. 실내식물은 화분형의 비율이 높으며 교실보다는 현관, 복도 등의 공용 공간에 우선 도입하고 있다. 실내식물에 의한 긍정적 효과에 공감하고 있으나 관리 어려움 등의 부정적 정서 또한 함께 인식하고 있다. 실내식물의 관리는 어느 정도 이루어지고 있으나 관리 예산, 담당자 지정, 관리정보 등의 측면에서 부족한 점이 인식되고 있으며 아울러 유지관리를 위해 예산지원, 업무분장, 관심 증가 등이 해결되어야 한다. 교원은 직원에 비해 식물 도입의 필요도가 높으며 식물은 유지관리, 환경정화, 안전성 측면에서 고려되어야 할 것이다. 향후 실내에 식물을 도입하여 학습, 휴식 등의 공간을 조성하는 재구조화 사업 등이 추진될 때 환경 특성에 적합한 식물의 선정, 예산을 비롯한 유지관리 계획 수립, 전문가의 지원 등이 고려되어야 한다. 또한 학생참여 프로그램, 교육자료 개발 등을 통해 식물 유지관리가 업무가 아닌 교육의 행위로 다루어질 수 있도록 하는 전략도 고려되어야 할 것이다. This study analyzes the current status and management characteristics of plants introduced into indoor spaces to identify strategies for developing green elementary schools. Indoor plants are predominantly potted and primarily introduced into shared spaces, including entrances and hallways, rather than classrooms. Although the positive effects of indoor plants have been acknowledged, there is also an awareness of negative sentiments, including the difficulties in managing them. Although some level of plant maintenance is carried out, there are recognized challenges, such as budget allocation, designation of responsible personnel, and availability of management information. To ensure proper maintenance, concerns like budget support, assignment of duties, and increased interest need to be addressed. Compared to other staff, teachers express a greater need for plants to be introduced, which should be evaluated in terms of maintenance, environmental purification, and safety. In future restructuring projects to create spaces for learning, relaxation, and other activities by introducing plants indoors, the following should be considered: selection of plants suitable for environmental characteristics; establishment of maintenance plans including the budget; and expert support. Moreover, strategies to approach plant maintenance as an educational activity through student participation programs and the development of educational materials should be considered.

정나라,한승원,김재순 인간식물환경학회 2020 인간식물환경학회지 Vol.23 No.5

Background and objective: This study analyzed the growth characteristics, in relation to the soil moisture content, of trees planted in an environment with limited soil depth to provide the baseline data for effective irrigation management. Methods: The experimental treatment was divided into soil moisture contents (SMC) of 20%, 15%, 10%, 5%, and 1%, and the respective watering times were set accordingly. As for plant materials, Nandina domestica, Euonymus alatus, Thuja occidentalis, Hibiscus syriacus, Pinus densiflora, and Pyracantha angustifolia, were chosen for this study, because they are highly likely to be used in urban street environments. Results: The minimum irrigation point suitable for each species was determined by considering various aspects of visual quality and water efficiency in terms of plant growth, including characteristics such as height, root diameter, rootlet development, and weight. Our results indicate that N. domestica should be watered so that the moisture content of the soil is of at least 5%, based on the balance between the stem and roots, as well as on visual quality. E. alatus and P. angustifolia are suitable for watering that results in at least 10% SMC, considering the height, root growth, weight, and visual quality of plants. As for T. occidentalis, it showcases moderate growth with a soil moisture content of at least 5%. Finally, the minimum irrigation time required to obtain 15% SMC is appropriate, in terms of plant growth, fresh weight, and visual quality, for H. syriacus and P. densiflora. Conclusion: This study suggested a basic irrigation guideline for container gardens where trees planted in environments with limited soil depth can be managed so that they are visually appropriate and in good condition of growth.

The Perception of Urban Residents on Creation and Management of Community Gardens

정나라,김광진,윤형권,한승원,유수진 인간식물환경학회 2019 인간식물환경학회지 Vol.22 No.5

This study analyzed the factors affecting urban residents' expectations and participation in community gardens to present basic data of guidelines for community garden management. Urban citizens valued the necessity of community gardens overall, especially residents with outdoor gardens. The experience of private gardens was important in perceiving the need for community gardens, which are public spaces. The creation of community gardens had high expectations for social aspects such as improving quality of life, health promotion, and community revitalization. In particular, residents living in individual housing have high expectations for revitalization of the community, and community gardens can be a mediator for forming and maintaining local communities. Through this, the citizens' perception on the role and function of the garden as a community space could be examined. Expectations for quality of life, health promotion, and community revitalization are factors affecting the necessity of community garden. Participation was high in the creation and management of the community garden, and the necessity of community gardens, expectation for community revitalization, and expectation for environmental purification are factors that affect participation in the management of community gardens. The amount of donations that the residents are willing to pay for community garden management was KRW 75,222 /year on average. Overall, residents with higher need for community gardens and higher social expectation showed higher participation. Urban citizens have high expectations for community gardens, and they perceive the importance of social aspects more than personal aspects such as community revitalization and quality of life. As a strategy for increasing community involvement, it is necessary to set up the processes, determine participants' composition and roles, and establish a system to promote participation. Considering welfare aspects such as community revitalization and improvement of residents’ quality of life, motivation and administrative support for participation in the creation and management of community gardens will serve as important factors.

Adopting Conceptual Metaphors as a Persuasive Device in Learners’ Argument

정나라 한국응용언어학회 2018 응용 언어학 Vol.34 No.4

Conceptual metaphors are pervasive in both mass communication and interpersonal exchanges and can play an important role in persuasion. The persuasive power of metaphors is most evident in the field of politics where it is actively studied. As a pedagogical adaptation, Littlemore (2005) conducted a study which taught the use of conceptual metaphors explicitly for the purposes of persuasion in a class debate, which forms the basis of this study to demonstrate how explicit teaching of conceptual metaphors as a persuasive device changes EFL adult learners’ argumentation. As a pre-test of learners’ argumentation capabilities, learners were asked to write their opinions on a given issue. Then, after having received instruction on utilizing conceptual metaphors as a strategy for persuasion, they were guided to make their arguments with the use of conceptual metaphors on the same issue. Through comparison and analysis of the results from the pre-test and post-test, the role that conceptual metaphors play in improving one’s persuasion was evaluated. The results show that the power of persuasion of both the pro and the con arguments is strengthened. This is consistent with the findings identified in the literature review, which theoretically illustrated the ways metaphors work as a persuasive device. In conclusion, this study contributes to the existing body of literature by verifying the persuasive power of metaphors with the addition of empirical evidence.

숲의 종류에 따른 생리적 치유효과 분석 - 고혈압과 당뇨병 환자를 중심으로 -

정나라,안득수,Jeong, Na-Ra,Ahn, Deug-Soo 한국조경학회 2015 韓國造景學會誌 Vol.43 No.5

본 연구는 숲의 종류에 따른 이용자의 생리적 효과를 분석하기 위하여 실시하였다. 숲은 편백나무숲, 졸참나무숲, 소나무 숲으로 구분하고, 실험대상 집단은 고혈압 환자(64명), 당뇨병 환자(59명) 및 일반인(59명)으로 구분하여 생리적 반응을 측정하였다. 생리적 반응은 뇌파, 심박 변이, 혈압, 맥박, 코티졸, 혈압 등을 지표로 선정하였다. 전체 피험자의 생리적 반응으로 숲의 스트레스 완화효과를 분석한 결과, 졸참나무숲은 중추신경계, 자율신경계, 내분비계 측면에서 다른 숲에 비하여 높은 스트레스 완화효과를 기대할 수 있다. 편백나무숲은 자율신경계를 제외한 지표에서, 소나무숲은 내분비계와 자율신경계 일부 지표에서 스트레스 완화에 기여할 수 있다. 그러나 소나무숲은 스트레스 완화효과에 있어서 상대적으로 효과가 적다. 고혈압 환자는 효과의 정도 측면에서 소나무숲보다 편백나무숲과 졸참나무숲에서 체류할 때 높은 혈압 강하의 효과를 얻을 수 있다. 당뇨병 환자는 혈당저하의 효과측면에서는 모든 숲이 효과적이나 특히, 졸참나무숲에서 체류하는 것이 높은 효과를 경험할 수 있다. This study analyzes the physiological healing effects on users according to forest types. Forest types are classified into Chamaecyparis obtusa, Quercus serrata and Pinus densiflora and the subjects of this study, 64 hypertensives, 59 diabetics and 59 ordinary people, were tested to observe their physiological effects. The index of physiological reaction comprises electroencephalogram(EEG), heart rate variability(HRV), blood pressure and cortisol level. An analysis of the stress-buffering effect from the physiological reactions of the overall subjects indicates that Quercus serrata forests have a higher stress-buffering effect than others in terms of central nervous, endocrine and autonomic nervous systems. Chamaecyparis obtusa forests are contributory to soothing stress in the central nervous and endocrine systems. Pinus densiflora forests contribute in some indexes of the endocrine and autonomic nervous systems. In contrast, Pinus densiflora forests are less influential on a stress-buffering effect than the other two. In the level of the effect for lowering blood pressure, Chamaecyparis obtusa and Quercus serrata forests are more effective than Pinus densiflora forests. Therefore, staying in the first two forests can heighten the healing effect of the lowering of blood pressure for hypertensive patients. Every forest is efficacious to lowering diabetic blood glucose levels. Spending time in Quercus serrata forests is more effective for hypoglycemic.

정나라,안득수 전북대학교 부설 휴양및경관계획연구소 2012 휴양및경관연구 (J East Asian Landscape Studies) Vol.6 No.2

본 연구는 숲에서의 체류시간에 따른 생리적 반응을 분석하여 건강증진에 미치는 효과를 규명하기 위하여 진행되었다. 연구는 전주시 건지산 일원의 편백나무 숲에서 평균 연령 53.33세의 여성 18명을 대상으로 숲 체류 5시간 동안의반응을 측정하였다. 생리적 반응으로 뇌파, 심박변이, 혈압, 맥박 등을 측정한 결과는 다음과 같다.숲에서 체류하는 동안 알파파 발생 빈도가 증가하여 생리적 안정이 이루어졌으며 숲에서 4시간 체류할 때 중추신경계의안정을 통해 스트레스 완화효과의 빈도가 높게 나타났다. 자율신경계 측면에서 이완 및 스트레스 완화를 설명하는부교감신경이 활성화되고 혈압 및 맥박의 감소 효과가 나타난 피험자 집단이 숲 체류 후 증가하였으며 최소 2시간부터4시간까지 효과가 나타난 피험자의 빈도가 지속적으로 높게 나타났다. 전반적으로 생리적 반응분석에 의하면, 숲 체류에따른 스트레스 완화효과에 있어서 숲에서 2-4시간 머무를 때 가장 많은 이용자가 스트레스 완화효과를 얻을 수 있을것으로 판단된다. This study provides scientific evidence supporting the efficacy of spending time in the forest in terms of physiological benefits. The participants included eighteen females(53±13.78 years old), and the study site was the Chamaecyparis Obtusa Forest of Gunjisan in Jeonju City. Brainwaves, heart rate variability, blood pressure, and pulse were measured once per hour while five hours in the forest. The results are summarized below; The alpha wave of a group of female subjects increased during their stay in the forest. This result affected their physiological stability. After four hours in the forest, the subjects’ central nervous systems stabilized. The parasympathetic nerves were activated to relieve stress, and their blood pressure/pulse rates reduced after their stay in the forest. In terms of the autonomic nervous system, the stress reduced between the second and fourth hours in the forest. Considering the physiological responses, staying in the forest is an effective means of relieving stress for at least two hours and up to four hours.

The Gypsy moth, Lymantria dispar (Linnaeus, 1758) (Lepidoptera: Erebidae) is a serious pest that attacks forest as well as fruit trees. We sequenced the 15,548 bp long complete mitochondrial genome (mitogenome) of this species. It consists of a typical set of genes (13 protein-coding genes, 2 rRNA genes, and 22 tRNA genes) and one major non-coding A + T-rich region. The orientation and gene order of the L. dispar mitogenome are identical to that of the ancestral type found in majority of the insects. Phylogenetic analyses using concatenated sequences of 13 PCGs and 2 rRNAs (13,568 bp including gaps) revealed that the L. dispar examined in our study, together with other geographical samples of L. dispar in a group forming the family Erebidae and consistently supported the monophyly of each family (Erebidae, Euteliidae, Noctuidae, Nolidae and Notodontidae), generally with the highest nodal supports.

The purpose of this study is to establish design guidelines for waterscape facilities of healing gardens in psychiatric hospitals. Data were collected through simulation and interview. The subjects included schizophrenic (n=42) and alcoholic (n=41) inpatients as well as medical staff personnel (n=40) at Maeumsarang Hospital. The results of this study are as follows: It was revealed that for all three groups the first preference was a natural flowing waterscape, and the second preference was a natural descending waterscape. The schizophrenic subjects had a greater preference for a static artificial waterscape and a descending artificial multistory waterscape than the other two groups. The alcoholic subjects preferred an ascending natural multistory waterscape. The analysis on the preference towards an ascending type and a descending type from the perspective of naturalness and complexity. Complexity had a greater influence than naturalness in the ascending waterscapes, and naturalness had more influence than complexity in the descending style waterscapes. Therefore, these factors need to be taken into consideration when designing either ascending or descending waterscape facilities. In general, the subjects preferred natural, dynamic and descending waterscapes to the artificial, static and ascending variety.
