The reference study was performed to investigate the nursing importance which was based a theoretical background related to horticultural therapy and to examine the possibility which horticultural therapy was applicable as a nursing intervention through analysis on a preceding study. The research subjects related to the areas of horticultural therapy which related as a nursing intervention, were psychological, physical, environmental, and psycho-social aspects. It is judged that the horticultural therapy is effective in treating depression, emotional disruption or anxiety. It seems to be also effective in increasing the muscular tension and, thereby, expanding the scope of joint movements. Such theories show that horticultural therapy may be a good alternative nursing means. Plants act to create a pleasant interior atmosphere by generating anion, controlling the temperature and humidity and purifying the air, and therefore, the horticultural therapy may be applied to clinic or environmental therapy. When horticultural therapy is used as a nursing intervention, patients' sociopsychological needs may be fulfilled. It has been found that horticultural therapy is instrumental in treating perceptive or emotional disruption, depression, loss of self-respect, disrupted everyday activities and social behaviors. In particular, horticultural therapy seems to be effective in managing chronic patients' crisis or improving life quality. Intervention method applied on a preceding study was activity therapy and scene therapy in the horticultural therapy The above findings suggest that the pro-environmental horticultural therapy is useful as a new paradigm of nursing or holistic nursing conducive to improvement of health. So, it is desirable to prove its effects by applying it in the clinic. In order to apply horticultural therapy as a nursing intervention, it will be necessary to educate nurses on principles and methods of horticultural therapy and encourage them to apply it in nursing and clinics. Moreover, it may well be necessary to develop landscape therapy as nursing intervention as well as a variety of horticultural therapy programs befitting the clinic conditions. On the other hand, we need to provide for some scientific ground for horticultural therapy through continued studies. In this regard, this study which focuses on patients' health improvement through change of environment. may well provide for a framework for such studies.

Apricot (Prunus armeniaca L.) cultivars show a gametophytic self-incompatibility (GSI) system, like other fruit species of Rosaceae family. Thus, it is necessary to determine their S-genotypes in order for stable fruit set in commercial cultivation. S-genotypes of apricots were determined by PCR and test crosses. Three sets of consensus primers designed from Prunus S-RNases were used to amplify fragments containing the first and second S-RNase intron, respectively. Through the results obtained from the 3 PCRs, we could identify SI genotypes of 33apricot cultivars. Several cultivars such as 'Heiwa', 'Yamagata No.3' and 'Shinsuoomi' had the self-compatible (Sc) allele. Self-pollination tests revealed that cultivars with Sc allele were self-compatible. Cross-pollination tests confirmed that there was cross-incompatibility between the cultivars with the same S-genotypes. These results might be very useful for growers for effective pollination and for breeders using these in cross breeding programs.

The objective of the present study was to review the current research about the outcomes of horticultural activity interventions in order to determine research trends and analyze the characteristics of horticultural activity interventions. We reviewed the literature using search engines such as the Web of Science, Proquest Dissertation and Theses, Academic Search Premier, Research Information sharing Service, and Korean National Assembly Digital Library to locate journal articles that include relevant search terms (e.g., gardening activity, gardening program, allotment garden, urban agriculture, horticultural therapy, and horticultural activity). We initially identified 14,414 journal articles that were published before April 2014 and selected 509 of the papers for review. We found that studies investigating treating children and adults 8 to 64 years old were the most common, and horticultural activities such as gardening outdoors, planting indoors, making crafts with live plants, arranging flowers, making crafts with artificial or pressed flowers, and other activities were usually combined. Short/medium term (11 to 20 sessions) horticultural activity programs were the most frequent, and most interventions were of medium duration (> 60 min to 120 min). Most of the studies focused on the psychological or emotional effects of horticultural intervention, such as its effects on emotional intelligence, self-esteem, stress, and depression. Further studies are needed to analyze the research methodology, specific outcomes, and strengths or weaknesses of studies investigating horticultural activity interventions.

Purpose: This study was conducted to ascertain the effectiveness of horticultural therapy by analyzing researches on horticultural therapy applied to elderly Koreans. Methods: We evaluated 401 research papers including dissertations on horticultural therapy applied to elderly Koreans from Jan. 2000 to Feb. 2016. We reviewed the appropriate 12 papers among them for the final analysis. Results: Horticultural therapy had physiological and psychosocial effects. First of all, it showed the physiological effects of reducing stress hormones. Outdoor horticultural therapy improved the gross motor movements of the body. Indoor horticulture therapy improved delicate cognitive & operating functions. Second, horticultural therapy showed the psychosocial effects of reducing depression and improving cognitive functions, language abilities, comprehension, daily activity, life satisfaction and sociality. But the effects appeared differently dependent on the implementation protocol & period of horticultural therapy, as well as the professionalism of the therapists. Therefore, if horticultural therapy were to be administered through nursing, it should be based on its key principle, in other words, the principle of action-interaction-response of horticultural therapy. Conclusion: The results of this study will be useful for developing therapeutic interventions through nursing. Also they will be helpful in applying horticultural therapy programs in nursing practice.

This study conducted a survey on 163 parents in Korea to investigate their interest in plants, experience in growing plants, and perception on horticultural activity programs (HAP) for their children. Most children (80.4%) of the respondents had experience participating in HAPs, and most of their experience occurred during school hours in preschool educational institutions more than once a month (60.3%). The more interest in plants and experience in growing plants the parents had, the more experience the preschoolers had in participating in HAPs, which implies that the experience of the parents with plants affected their children's participation in HAPs. Parents' most preferred location of HAPs was preschool educational institutions, and most preferred time was school hours with a frequency of more than once a week (57.1%), which is more frequent than the current status of HAPs in preschool educational institutions. Parents also responded that the most preferred instructors of HAP has are those with a professional background in horticulture. Among the activities in HAP for preschoolers, parents most preferred cooking (M = 4.05) activity, and they did not dislike any of the activities. They responded that the facilities for HAP needed to be improved to make HAP more active in preschool educational institutions. Overall, based on the current results, developing suitable HAPs and facilities for preschoolers, fostering professional HAP instructors, and educating parents about horticulture would enhance HAPs in preschool educational institutions, thus providing preschoolers with many benefits of HAPs.

Background and objective: Horticultural activity is one of the most basic elements of horticultural therapy, which brings about therapeutic effects for participants through various plant-related activities. The main objective of this study was to verify the results of previous research, which suggested six types of activities from the exploratory factor analysis. Methods: To meet the purpose of this study, a questionnaire was designed to determine the preferences for 6 types of the horticultural therapy activities. The survey was conducted on 703 people from March 7 to June 20, 2019. The data of 674 cases were used into the final analysis, excluding unreliable responses. Descriptive statistics, and reliability analysis were performed using IBM SPSS Statistics 25, and confirmatory factor analysis was performed using IBM SPSS Amos 21. Results: First, horticultural therapy activities were classified into 6 types from the exploratory factor analysis, as conducted in previous research. The confirmatory factor analysis provided that the fit of the final model was satisfactory with χ² = 1,300.590 (p < .001), RMR = .045, GFI = .876, RMSEA = .062, NFI = .914, TLI = .905, CFI = .914. Conclusion: This result revalidated that the mode with 6 types of horticultural therapy activities from previous research is appropriate criteria for the classification of horticultural activities. The model could be used to design more systematic horticultural therapy programs that meet the needs or circumstances of the subject, or that are suitable for necessary therapeutic intervention methods.

The purpose of this study was to develop an effective horticultural activity program for the vocational rehabilitation of people with mental disabilities. The subjects of this study were seven persons with mental disabilities in the vocational rehabilitation team of a public health center located in G city, Gyeongsangbuk-do. A total of 10 horticultural programs were held from October 10 to December 11, 2018. Five programs were selected among those that were easy for the persons with mental illness to handle and their preference was high. In each session, the same task was repeated 10 times and finally changes in hand functions and working speed were measured. As a result, the assembly task of the Purdue Pegboard test was 23.6 (SD = 10.5) before the program, 26.6 (SD = 11.5) after planting, 27.7 (SD = 12.2) after wrapping pots, and 28.0 (SD = 13.9) after making mini flower baskets, 26.9 (SD = 12.0) after wrapping a single flower, and 29.1 (SD = 11.9) after making corsages. There was a significant difference between the five programs (p = .016). As a result of measuring the time taken to produce the same 10 products, the average planting time was 9.9 (SD = 4.0) minutes in the first class and 6.0 (SD = 2.3) minutes in the second class (p = .018), and making mini flower baskets was reduced from 35.2 (SD = 10.1) minutes to 21.0 (SD = 7.7) minutes (p = .018), wrapping a single flower from 23.3 (SD = 7.9) minutes to 16.2 (SD = 7.3) minutes (p = .043), and making corsages from 53.6 (SD = 15.9) to 40.8 (SD = 16.8) minutes (p = .043). The working time was significantly shortened in the second class compared to the first class. The class for wrapping pots was shortened from 52.7 (SD = 11.7) to 49.6 (SD = 17.8) minutes, but there was no significant difference (p = .398).

Tulip (Tulipa L.) is one of the most important ornamental geophytes in the world. Analysis of molecular variability of tulips is of great importance in conservation and parental lines selection in breeding programs. Of the 70 genic microsatellites, 15 highly polymorphic and reproducible markers were used to assess the genetic diversity, structure, and relationships among 280 individuals of 36 wild and cultivated tulip accessions from two countries: Iran and the Netherlands. The mean values of gene diversity and polymorphism information content were 0.69 and 0.66, respectively, which indicated the high discriminatory power of markers. The calculated genetic diversity parameters were found to be the highest in wild T. systola Stapf (Derak region). Bayesian model-based STRU CTU RE analysis detected five gene pools for 36 germplasms which corresponded with morphological observations and traditional classifications. Based on analysis of molecular variance, to conserve wild genetic resources in some geographical locations, sampling should be performed from distant locations to achieve high diversity. The unweighted pair group method with arithmetic mean dendrogram and principal component analysis plot indicated that among wild tulips, T. systola and T. micheliana Hoog exhibited the closest relationships with cultivated tulips. Thus, it can be assumed that wild tulips from Iran and perhaps other Middle East countries played a role in the origin of T. gesneriana, which is likely a tulip species hybrid of unclear origin. In conclusion, due to the high genetic variability of wild tulips, they can be used in tulip breeding programs as a source of useful alleles related to resistance against stresses.

The purpose of this study was to understand the current status of education and programs and to identify the items that urban residents need most for garden management. First of all, there were 45 sites (40.5%) with gardens operated by city and county local governments nationwide, and 41(91.1%) of them had dedicated staff (1.8 persons on average). The average area of gardens was 18,623 m², garden area per person was 20.27m², the average number of participants was 683, and the average period of use was 8.69 months. In addition to gardening activities, 14 (31.1%) out of 45 sites were operating small group meetings, with an average of 2.29 meetings and 67 participants. In the satisfaction survey after gardening activities, 88.9% of 18 sites were satisfied. According to the questionnaire about education and programs related to garden users, an average of four sessions were conducted per education. In terms of education, the contents were in the following order: basic education on garden cultivation (33.9%) > prior education on garden operation (28.9%) > pest control (14.0%) > eco-friendly management (11.6%) > pesticides and Positive List System (9.9%) > others (1.7%). Over 95% of the respondents were generally satisfied. Regarding the perception survey on which items are needed to develop garden management guidelines, the most necessary items were in the order of crop management (38.7%) > public garden etiquettes among users (27.9%) > pest control (14.4%) > weed management (13.5%) > activities using harvest (5.4%). The contents that are to be included in the guidelines were in the order of garden planning and crop selection (17.2%) > cultivation techniques and schedule (16.5%) > pest and soil management (15.7%) > introduction of garden crops and gardening models (12.7%) > garden etiquettes (10.7%). In establishing urban garden management plans by region, the results will have high utility value as the basic data for continuous garden operation by setting a direction that meets the regional characteristics as well as the needs of urban residents.

This study is based on the premise that a garden space is a place that not only requires physical labor but also encourages conversation in the gardening group. We suggest the use of urban gardens as a place to revitalize local communities by promoting people to participate in various event programs. Through the theoretical study, we set the requirements that can be applied to "urban garden events". We developed measurement items and scales to be used as variables of each construction concept. Our survey was conducted on adults aged 19 and above who visited the 8th Korean Urban Agriculture Expo. Out of total 310 copies of the distributed questionnaire, only 298 effective samples were used in the empirical analysis. We can assume that people want to revitalize local communities based on the fact that 71 (23.8%) participants said they thought the purpose of the event is to achieve unity among residents. Throughout analysis, 15 of the necessary items were confirmed and classified into two factors: image of event (Factor 1) and evaluation item (Factor 2). As a result of verifying the relationship between educational level for Factor 1, age was significant in five items and education level was significant in six items. For Factor 2, four items were effective in relation to education level, while significant results were not found in relation to age. These results are expected to be significant if the intellectual curiosity of the residents is satisfied and the demand base of the urban garden events according to the characteristics of city people is expanded. Based on this study, it is necessary to conduct research on the use of urban gardens as an event with social functions as well as various programs that can be carried out in gardens to build and revitalize the community.
