The purpose of this study was to identify differences by business motivation of agro-healing farm s in Korea. A survey was conducted for entrepreneurs in agro-healing farmers with self-administered questionnaires. Main results of this study were as follows: First, business motivation of agro-healing farm s in Korea can be classified to 1) education-oriented, 2) care-oriented, and 3) sale revenue-oriented motivation. Second, care-oriented farms provide healing services to people in need like the disabled. These farms may be required a long-term program such as residence-required format. And these farms need supports of health and medical service personnel or institutions. Third, sale revenue-oriented farms have sources of main income from agricultural products or processed goods made in these farms. Therefore, these farms may be required a business strategy such as product development, marketing rather than agro-healing programs. fourth, the estimation of a Multinominal logistic regression model determines the characteristics of agro-healing entrepreneurs who are most likely to opt for each type motivation of participating for agro-healing farm business. the most important determinants on business motivation of agro-healing farms were 'participants type in programs', 'program operating time', 'supporting health and medical service personnel or institutions' and 'program revenue ratio in farm operating revenue'.

Recently, there has been increased attention to the development of new plant cultivars with enhanced resistance to biotic and abiotic stress. To develop ginseng cultivars with such traits, systematic breeding programs and comprehensive field studies are prerequisites. In this study, we applied a pure-line selection method to identify a ginseng cultivar with enhanced stress resistance. Phenotypic and agronomic characteristics, seed yield, and physiological responses to biotic and abiotic stresses were investigated according to the guidelines of the International Union for the Protection of New Varieties of Plants (UPOV). In the newly developed 'Kowon' cultivar, the time of emergence, flowering, and berry maturity were intermediate between those of the controls, 'Yunpoong' and 'Chunpoong'. The stem length of 'Kowon' was intermediate, whereas the root length was shorter and the main root diameter was greater than those of 'Chunpoong'. In local adaptability tests conducted in three regions, the yield of 'Kowon' was $666kg{\cdot}10a^{-1}$; 27% and 4% higher than that of 'Chunpoong' and 'Yunpoong'. Diseases such as Alternaria blight, Phytophthora blight, mulberry mealybug, and nematode infestation did not occur in 'Kowon'; and it also exhibited moderate resistance to damping-off and anthracnose. In these cases, yellow spots occurred on aerial parts and the rusty skin of the root, and it exhibited moderate resistance at high temperatures. Our study demonstrates that 'Kowon', which has a high root weight and enhanced biotic/abiotic stress resistance, is a superior cultivar that could increase farmers' income.

The purpose of this study is to investigate the effect of gardening programs using vertical gardens on helplessness, depression, and self-esteem in patients with chronic mental disorders. This study was applied to 21 patients with chronic mental disorder who were admitted to the rehabilitation hospital of E Hospital in Seoul from June to October 2018. The group was treated as an experimental group (N = 21) 5 times a week. For 20 weeks, each session lasted 30 minutes. Patients in the experimental group programmed 4 sessions of general occupational therapy, which combined treatments to improve cognition and training, and 1 session of a horticultural program using a vertical garden. Helplessness, depression, and self-esteem were evaluated for pre and post evaluation of the horticultural program. After completing the program, the average score of helplessness in the experimental group decreased by 0.91 points from 47.38 to 46.47, and there was a statistically significant change (p=0.043). The mean score of depression in the experimental group was 9.23 before and after 9.08, which was statistically significant (p = 0.035). The average score of self-esteem in the experimental group increased by 3.14 points from 27.99 to 31.13 at a statistically significant level (p = 0.001). This result suggests that a gardening program using vertical gardens has an effect on helplessness, depression, and self-esteem in patients with chronic mental disorders. And this means that long-term plans and effective programs for recovery from chronic mental disorders to the community are needed. With a horticultural work program using a vertical garden, the helplessness of the mentally impaired in a closed treatment space is restored, and such treatment space needs to be increased.

This study is to analyze the current state, trend, and preference of the three chrysanthemum festivals representing South Korea that are hosted by local governments, and it is to be used as the basic data for preparing effective plans for the chrysanthemum festivals. The study was conducted from April 20, 2013 to November 25, 2017, and literature review, online search, interviews with persons in charge, field survey, and questionnaire survey were performed. As a result of the field survey, all three festivals had their space structures divided, themes decided and space images depicted based on chrysanthemum sculptures. The landmarks of the city, cultural assets, or great figures were selected to the main theme of the major chrysanthemum sculptures. The sculptures were decorated realistically for users to easily recognize the image. The main chrysanthemum sculptures tended to be introduced repeatedly. As results of the current state of visit and preference, it was found that the number of visitors has increased every year, along with revisits. The satisfaction and the preference for the festival were evaluated positively, and the chrysanthemum festival has become a local festival representing autumn, and a resource for vitalization of the regional economy. However, as a result of the survey, insufficient parking space and resting place, change of image of the sculptures, experience programs, and food shall be improved in order to increase the users satisfaction.

To analyze the effectiveness of horticultural therapy reported in research papers, a meta-analysis was carried out with 108 of 377 Korean and overseas research papers on horticultural therapy from 1985 to February 2009 (196 Korean dissertations, 113 Korean journal articles, 5 overseas dissertations, and 63 overseas journal articles). The results revealed a large effect size of 0.71. The effectiveness according to the type, age and number of participants were also analyzed. The therapy was most effective in children, and it was more beneficial for children with special needs and elderly people affected by dementia than for the typical population. The greatest effect was found with group sizes of five people or less, and when carried out by researchers from departments related to horticultural therapy than by researchers from unrelated fields of study. The most effective horticultural therapy programs involved floral decorations; and participants who took part in 21 to 30 sessions or at least 31 sessions benefited the most. Among the main effects of short-term horticultural therapy are cognitive, social, physical and emotional; the greatest effect was observed in the physical domain.

Recently, new ginseng cultivars having superior agricultural traits have been developed in Korea. For newly developed plant cultivars, the identification of distinctiveness is very important factors not only in plant cultivar management but also in breeding programs. Thus, eighty-five inter simple sequence repeat (ISSR) primers were applied to detect polymorphisms among six major Korean ginseng cultivars and two foreign ginsengs. A total of 197 polymorphic bands with an average 5.8 polymorphic bands and 2.9 banding patterns per assay unit across six Korean ginseng cultivars and foreign ginsengs from 236 amplified ISSR loci with an average 6.9 loci per assay unit were generated by 34 out of 85 ISSR primers. Three species of Panax ginseng including the Korean ginseng cultivars, P. quinquefolius, and P. notoginseng, could be readily discriminated using most tested primers. UBC-821, UBC-868, and UBC-878 generated polymorphic bands among the six Korean ginseng cultivars, and could distinguish them from foreign ginsengs. Sequence characterized amplified region (SCAR) marker system was introduced in order to increase the reproducibility of the polymorphism. One SCAR marker, PgI821C650, was successfully converted from the randomly amplified polymorphism by UBC-821. It showed the expected dominant polymorphism among ginseng samples. In addition, the specific polymorphism for Sunwon was generated by treating Taq I restriction enzyme to polymerase chain reaction products of PgI821C650. These results will serve as useful DNA markers for identification of Korean ginseng, especially Sunwon cultivar, seed management, and molecular breeding program supplemented with marker-assisted selection.

This study was carried out to develop a model system using selection method for disease resistant plant breeding programs using a herbicide bialaphos-resistant patII gene as a gene-based marker. Spraying bialaphos could eliminate the susceptible plants from the segregating populations such as ${F_2}^{\prime}s$ and thereafter. Tomato cv. Momotaro-yoke was transformed with patII gene 60 independent transformants were acquired. Total 42 transformants were analyzed in transgene copy numbers by Southern blotting and the segregation ratios for the bialaphos resistance. Statistical analysis revealed that the transgene copy numbers and the segregation ratios were not always coincided, especially having the tendency of underestimating the real numbers of the transgenes in the multicopy lines. A two-stepwise screening method was applied to select $T_1$ tomato plants which linked the transgenic patII to a disease resistance gene (I2 and Ve). Based on the resistant to susceptible ratios, T-20 plant was finally selected due to the estimated linkage 12-13 cM between the patII gene to the I2 gene on chromosome 11. This newly developed system could be applied to any economical crop in breeding programs.

The purpose of this study is to investigate the effect of gardening programs using therapeutic gardens on the fall efficacy of the elderly. This study was applied to 31 elderly facility users from April to August 2019 at a nursing home P located in Gyeonggi-do. Among the 31 participants who participated in the program, 16 subjects in the experimental group and 15 subjects in the control group were randomly selected. As for the experimental group program, a fall program consisting of fall education and strength training four times a week and a horticultural occupational program were implemented once a week in a healing garden for a total of 15 weeks. The control group performed fall program for 30 minutes 5 times a week for a total of 15 weeks. The fall efficacy of the tested group increased by 5.50 points from 29points before the program to 34.50points after the program, and statistically significant results were obtained (p=0.000). The control group who only progressed the fall program increased 3.63 points from 28.87points before the trial to 32.50points after the trial, and statistically significant results were obtained (p=0.000). From this result, it can be confirmed that the horticultural program using the treatment garden has the potential as a program related to falls. In the future, various studies are needed so that gardening programs using gardens can be applied to prevent falls of the elderly.

The present research was conducted to study genetic relationship and cultivar identification in sweet potato (lpomoea batatas) using RAPD method. Thirteen cultivars of sweet potato in Korea were classified by UPGMA clustering method into three groups as follows; group I was corresponded to 'Choongsung100'; group II, 'Eunmi', 'Saengmi', 'Suwon147' and 'Yulmi'; group III, 'Hongmi', 'Jinmi', 'Kwandong95', 'Seonmi', 'Wonmi', 'Shinyulmi', 'Jeungmi', and 'Poongmi'. Identification using RAPD was generally consistent with breeding pedigree of those parents. However, inconsistent results may be caused by clonal variation. The results presented in this study suggest that RAPDs in sweetpotato are likely to be useful for cultivar identification and various procedures in breeding. The use of various DNA marker system assists selection programs for economically important trait, and may facilitate selection in earlier growing stage. This systems may enhance the prospects for improving sweet potato cultivar by accurate marking desirable traits at DNA level.
