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.

조경수 농장의 소나무 재배관리 실태분석1) – 고창군 사례를 중심으로 –

정나라,안득수 전북대학교 부설 휴양및경관계획연구소 2021 휴양및경관연구 (J East Asian Landscape Studies) Vol.15 No.2

본 연구는 고창군의 소나무 재배 농가를 대상으로 재배관리 실태를 파악하여 산업 활성화를 위한 개선방안을 제시하고자 하였다. 소나무 재배는 병해충관리, 수형관리, 시비 등이 중요한 과정으로 건전한 생육 상태와 상품 가치가 높은 수형 관리를 유지하는 것이 중요하다. 1년에 1회 이상 가지치기, 시비, 농약 살포 등의 관리가 이루어지고 있다. 또한 지속적으로 재배관리를 위한 비용이 투입되고 있으며 특수목 구입과 가지치기 등에 많은 비용이 사용되고 있다. 소나무 재배 농가 는 노동력 부족과 가지치기의 어려움을 지적하였다. 재배관리 현황을 기초로 소나무 생산 활성화 를 위한 방안을 제안하면 첫째, 노동력 부족의 문제를 해결하기 위한 기계화 및 스마트 시스템의 적용이 필요하다. 이를 위해서는 현재의 노지 생산방식보다는 컨테이너재배 방식이 효율적이다. 둘째, 수형 관리를 위한 가지치기 기술의 습득을 위한 지원이 요구된다. 가지치기는 소나무 품질 을 결정하는 중요한 관리기술로 전문가 의존도가 높으므로 지속적인 교육, 정보 제공 등의 지원이 이루어져야 한다. 셋째, 수요에 대응한 맞춤형 재배관리가 진행되어야 한다. 규격화된 대량 생산의 재배목과 우수한 상품성을 가진 대형목인 산채목 등으로 구분하여 수요에 적합한 품질을 갖도록 재배관리가 이루어져야 한다. This research assesses the current status of commercial pine tree farming in Gochang-gun, Korea, and presents prospective measures to improve and revitalize the industry. Cultivation of pine trees is an ecologically important process for proper form management, control of pests, soil fertilization, and cultivation of a diverse and healthy ecosystem. Pine tree management requires continual expenditure and upkeep to provide for necessary pruning, spraying, fertilization, and purchase of healthy seedlings and specific tree species. In pine-growing farms, pruning, fertilization, and pesticide spraying are performed at least once a year. Besides monetary costs, this cultivation is labor-intensive, particularly pruning. A lack of labor and resultant difficulties in keeping pine pruned is a frequent complaint among pine farmers in the region. Based on this, we propose that it is first necessary to more widely apply mechanization and smart farm systems to solve the problem of labor shortage. To this end, container cultivation is a more efficient method than the current production method of open field culture. Second, the industry requires support for increasing the availability of skilled labor which is qualified for the required pruning necessary for good forest management. Pruning is an important management technique that strongly influences the quality of pine trees, and since proper application is highly dependent on experts, support such as continuous education and provision of information should be provided. Third, customized cultivation management should be carried out in response to demand. Cultivation management should be carried out to ensure quality suitable for demand by classifying the trees into standardized mass-produced cultivated trees, and large-sized trees with excellent commercial quality.

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.

Growth Characteristics of Woody Plants for Irrigation Management of Container Gardens

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.

Community gardens provide the community with a green area for its residents to enjoy and socially interact with other gardeners. The expected benefits of participating in a community garden, aside from greater access to fresh produce, include increased mental health as well as improved general well-being stemming from increased exercise and socialization. The following is the research result conducted to provide a basic data for the construction of a community garden in a village. Once a community garden is put in place, the residents would intend to utilize it for their rest, stroll, exercise and appreciation. The number of respondents who would use a garden more than once a week turned out to be high, the reason behind which is construed as their willingness to utilize the garden as a place where they could relatively spend more leisure time later on given that the higher the respondents’ age became, the more often they would use the garden. Furthermore, as weekday afternoons’ or weekend afternoons’ participation has been high, it would be desirable if the garden revitalization or a community programs were conducted in line with this timeframe. The efficiency of the community garden would be enhanced when it is located within one kilometer where a person can walk in about 20 minutes. It is anticipated that once the community garden is built, it would be utilized as local residents’ hobby place and that it could serve as urban green space conducive to improving the landscape of a village, and overall, there are high expectations relating to this. As living infrastructure, the community garden can be utilized not just as a space for local residents’ leisure activities and rest areas but for their interactions. Thus, it is estimated that instead of applying a cookie-cutter garden design to all communities, a formulation of a garden needs to be made in a way that designs the space reflective of the characteristics of a community and that introduces needed facilities.

매미나방의 미토콘드리아 게놈 분석

정나라,남영우,이원훈,Na Ra, Jeong,Youngwoo, Nam,Wonhoon, Lee 한국응용곤충학회 2022 한국응용곤충학회지 Vol.61 No.3

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.

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.
