The aim of this work is to evaluate the potential of oriental melon (Cucumis melo L. var. makuwa Makino) seeds for the management of type 2 diabetes by controlling glucose absorption. The ${\alpha}$-glucosidase and ${\alpha}$-amylase inhibitory effects of the hexane extracts from oriental melon seeds were investigated. A bioassay-guided fractionation technique was used to elucidate the principal active components. The results show that the hexane extract from oriental melon seeds exhibited high inhibitory activities against ${\alpha}$-glucosidase and ${\alpha}$-amylase. The hexane extract was further fractionated into four sub-fractions. Among them, the sub-fraction F-1 exhibited the most potent anti-diabetic effect. The active components were isolated and identified by gas chromatography/mass spectroscopy (GC-MS). Free fatty acids showed significant hypoglycemic activity (p < 0.001) and fatty acid composition influenced enzyme inhibitory activities. These results suggest that oriental melon seeds could be used to prevent type 2 diabetes.

The objective of this study was to determine inhibitory activities of four volatile plant essential oils (cinnamon oil, fennel oil, origanum oil and thyme oil) on in vitro growth of Fusarium oxysporum f. sp. fragariae causing Fusarium wilt of strawberry plants. Results showed that these essential oils inhibited in vitro conidial germination and mycelial growth of F. oxysporum f. sp. fragariae in a dose-dependent manner. Cinnamon oil was found to be most effective one in suppressing conidial germination while fennel oil, origanum oil and thyme oil showed moderate inhibition of conidial germination at similar levels. Cinnamon oil, origanum oil and thyme oil showed moderate antifungal activities against mycelial growth at similar levels while fennel oil had relatively lower antifungal activity against mycelial growth. Antifungal effects of these four plant essential oils in different combinations on in vitro fungal growth were also evaluated. These essential oils demonstrated synergistic antifungal activities against conidial germination and mycelial growth of F. oxysporum f. sp. fragariae in vitro. Simultaneous application of origanum oil and thyme oil enhanced their antimicrobial activities against conidial germination and fungal mycelial growth. These results underpin that volatile plant essential oils could be used in eco-friendly integrated disease management of Fusarium wilt in strawberry fields.

Background and objective: This study was conducted to identify the components of kindergartener horticultural education by deriving objective components of horticultural education using the Delphi survey method, and then to provide basic data that can be used when creating horticultural programs in the regular curriculum. Methods: A total of 32 experts including professors of early childhood education, kindergarten directors, horticultural therapy professors, and horticultural therapists were selected as the Delphi panel. Of the 32 selected, only 29 answered all three rounds of the surveys. For the first round of the survey, an open-ended questionnaire, was used, and in the second and third rounds closed-ended questionnaires were used. Results: Results indicated that under the category of the goals of horticultural education, there were 7 items related to the current problems of horticultural education, 16 items related to the need for horticultural education in the smart age, 18 items related to the direction of horticultural education, and 5 items related to the areas most suitable for horticulture education for young children in the Nuri Curriculum. Results in the category of the implementation of horticultural education indicated that 2 items related to horticultural education hours, 3 items related to the venue for horticultural education, 2 items related to the activity types applicable to the Nuri Curriculum, and 4 items related to the objects of horticultural activities were derived. As the current problems of horticultural education, the following items were identified: event-oriented activity (M = 4.24) and lack of kindergarten teachers' opportunities for systematic gardening education (M = 4.21). The results related to the necessity of horticultural education indicated the following items: education on respect for life through caring (M = 4.59), emotional intelligence and stability (M = 4.55), directly experience of the growth process of plants (M = 4.55), and development of the five senses (M = 4.55). Finally, within the direction of horticultural education: nurturing the desire to live with nature (M = 4.50), and learning about life (M = 4.44) was identified, which had higher averages. Within the areas of the Nuri Curriculum, which is most consistent with horticultural education, nature exploration (M = 4.69) and the integration of all areas (M = 4.59) were derived as priorities. Also, regarding the implementation of horticultural education, the following items were derived as the priority from the expert group: 30-40 minutes (M = 4.14) and 40-50 minutes (M = 4.14) for class periods, outdoor garden in a kindergarten(M = 4.66) for the venue of gardening education, outside play (M = 4.59) for the activity type, and vegetable crops (M = 4.55) for the objects of gardening activities. Conclusion: It is significant that the goal and implementation of kindergartner horticultural education were objectively derived through collecting opinions of expert panels. Based on the results of this study, a horticultural education program for kindergarten teachers should be implemented.

This study was conducted to investigate psychological and physiological changes of elderly affected by agro-healing activities. To meet the purpose, we conducted an agro-healing program with 20 elderly participants (average age 77.6±5.84 men and women) and once a week in total seven sessions. The Korean version of the Brief Encounter Psychosocial Instrument (BEPSI-K), Korean version of the Short Form of Geriatric Depression Scale (SGDS-K), participants' satisfaction with the program, Salivettes system method, and blood pressure were measured to find out the effects of agro-healing activities. BEPSI-K decreased by 5% in the high stress group although it was not statistically significant. The result of program satisfaction showed that 75% of the participants are satisfied with these activities. We investigated how many and what kind of chronic diseases the participants have had before they joined the program. As a result, hypertension was most common(35.6%), followed by hyperlipidemia, diabetes, arthritis, lumbago, osteoporosis, and heart disease. Systolic blood pressure after the activities decreased significantly from 144.75mmHg (stage 1 hypertension), to 132.90mmHg(prehypertension stage). As a result of analyzing the correlations between general matters such as age, education level, average income of the participants, psychological scale and number of diseases, it was found that participants' satisfaction had a negative correlation with depression. In conclusion, agro-healing is very useful in relieving stress or lowering blood pressure for the elderly whose most common disease is hypertension. Agro-healing activities are proved to have positive uses in reducing the problems of the modern society with severe issues of the aging population.

The purpose of this study was to investigate the effects of horticultural activities with reminiscence materials and singing songs on the ability to recall words and depression in the elderly with mild dementia. A total of 20 sessions of a horticultural therapy program was held once or twice a week from July 14, 2015 to November 3, 2015 for the elderly with mind dementia at the social welfare center in D city. The subjects of this study were 13 women and the mean age was 81.2 years. The ability to recall words significantly improved from $8.6{\pm}1.8$ before the program to $9.4{\pm}0.6$ after the program (p=.012). However, there was no significant difference in the score of depression after the program. Synergistic effects were generated by applying horticultural activities, singing and reminiscence therapy activities simultaneously, and it was effective in recalling memories. As emotional functions were associated with hormones in vivo, there were emotional ups and downs at each session and short-term alternative therapies were not sufficient to completely eliminate neurotoxic substances caused by dementia.
