According to survey for development of container to producers who carry out container cultivation, the most important thing is ‘Realization of cultivation techniques (Prune roots, Water saving, Heat conservation)’ as the basis for the design of container and this survey showed that the best one is ‘small and medium-sized container of less than 50L’ as the size of container suitable for cultivation. To investigate the growth characteristics of plants according to the type of container, we classified the container into three types and then planted public plants Pinus densiflora, Cornus kousa, Chionanthus retusa in 12types of containers repeatedly three times. After Comparison of the growth of the Root-collar diameter, Rib-type is showed the highest growth of the Root-collar diameter in case of Pot-type. So, active effects of prune roots impact on positive the growth of plants. Grow inside the ground-type is showed the highest in case of Growing Bag-type and Root skirt-type is showed the highest in case of Bag in pot-type. After, In subsequent studies, based on this study, produce development prototype of design container and test them. and then to investigate the possibility of applying to the farmhouse.

The aims of this research were to examine whether horticultural activity is appropriate for personality education to prevent reformatory students from redelinquency, to make use of it for developing educational programs and to take advantage of the research as based information. In order to accomplish the purposes, the researches and surveys were taken in four parts targeting 262 reformatory students from five different Youth Detention Centers out of ten centers in the country: simple mental health diagnostic inventory, general characteristics, preferences of personality programs that are currently underway to juvenile delinquents in juvenile protection education institution, and awareness and preference of the plants and horticultural activities. First of all, as a result of simple mental health diagnostic inventory, ‘depression’ appeared to be the highest while ‘hostility’, ‘somatization’, ‘obsessional thinking’, ‘interpersonal sensitivity’, ‘anxiety’ and ‘psychosis’ emerged in the order. Secondly, as a result of preferences of personality programs, ‘social work’ appeared relatively the highest, while ‘Do-dream program’, ‘art therapy’, ‘career exploration’, and ‘sex education’ showed in the order. Thirdly, 53.3% students responded that personality programs through horticultural activities is desirable and 84% appeared that they prefer it. The most preferred plant species were fruit trees (strawberries, apples), flowers (roses, herbs) and vegetables (Scatter cucumbers, tomatoes). The most interesting garden activities were ‘growing (cultivation)’, ‘decorating (decoration and craft)’ and ‘feeling plants (appreciating).’ Therefore, it is well ascertained that juvenile delinquents in juvenile protection education institution consider introducing horticultural programs into personality education positive. Based on these results, it is identified that more various and specialized horticulture programs to prevent reformatory students from redelinquency should be developed for practical use.
