As the interest in urban agriculture and people’s demand for eco-friendly food grow, the number of urban gardeners who directly grow and harvest will increase. The aim of this study was to compare the effect of conventional fertilizer with the effluent water from the biofloc technology inland aquaculture in the concept of resource circulation as a substitute for fertilizer used in urban agriculture. In order to verify the effect of fertilizer on the cultivation of cherry tomato, tomato seedlings were transplanted on the horticultural soil without nutrients and treated for 8 weeks. Experimental treatment was carried out in five treatments: control, hyponex solution (HS), slow-released fertilizer (SF), effluent water daily treatment (DE), and effluent water treatment once a week (WE). The growth characteristics of the cherry tomatoes showed significant differences among the treatments except for root length. In the case of plant length was shown HS=WE›DE=SF›control, and stem diameter was shown DE=SF ›WE=HS›control. It was found that HS and WE were not significantly different in shoot length and diameter, and DE and SF showed no difference. In the case of number of leaves, HS, DE, and WE showed a significantly higher level than SF and control. In other growth characteristics, DE and SF showed higher growth. As for the growth of cherry tomato fruit, the sugar content did not show any significant difference among the treatments except control. Weight per fruit and yield were significantly higher in HS and WE than DE and SF. Based on these results, it is considered that the use of effluent water is comparable to the use of urban agricultural fertilizer as compared with chemical fertilizers in cultivating crops.
The Purpose of this study was to develop integrate education program and method for college students, We run English education program and Farming activities half and half; such as endangered plant surveys, gardening, mulching, visiting university attached farm, and local tourism farm for 4 weeks. The results of this study are as follows: First, Agro-entrepreneurial intention is more likely to be found in the English & Farming activity participants, and Male students than English&culture activity participants, and female students respectively. In the context of the effectiveness of the English Learning Program, students with poor English learning usefulness have strong desire to build up their own business, whereas those with higher English learning suitability are more likely to have a strong desire to start farming. In terms of entrepreneurship, the tendency toward entrepreneurship, risk sensitivity. and in terms of self – efficacy, The bigger the confidence, the greater the will to start an agricultural business. The results supported that The English education program with farming activities has a significant and positive influence on Agro-entrepreneurial intention in college students.
The Purpose of this study was to develop Agro-entrepreneurial education program for agriculture college students, In order to investigate the relationship between the types of agricultural starup business and the entrepreneurial intention, we surveyed 224 Agriculture college students in the 3rd and 4th grades using a questionnaire. The results of this study are as follows: First, college students majoring in agriculture have very low interest in establishing agricultural business. Second, there is a difference in the perception of agricultural entrepreneurship between agriculture college students who are engaged in farming as family business and those who do not. agriculture college students who are engaged in farming as family business (Successive Students). The effect of entrepreneurship on entrepreneurship was different by family business for successive students, initiative and challenge spirit had a significant impact on the agro-entrepreneurial intention. otherwise, non successive students have impacted by innovation and social responsibility. Third, in terms of entrepreneurship, the lower the challenge spirit, the greater the willingness to start an agriculture business. The results supported that for agriculture college students, in order to educate individual customized farming management, it is necessary to confirm whether or not agriculture is a family business.
This study was conducted to analyze the correlation between cultivation environment, cropping system, and the quality of cut flower in autumn-winter season chrysanthemum‘Jinba’, and to suggest the cultivation factors that can improve the quality of cut flower. It was examined for cultivation environment such as average day and night temperature, average day and night relative humidity, average day and night vapor pressure deficit (VPD), and integrated solar radiation of 4 farms planted in mid-October. Also, it was surveyed for cropping system such as cutting condition, growth period, irrigation method, soil chemical properties. Chrysanthemum ‘Jinba’ was harvested in order to investigate the quality of cutting of four farms, and then growth, chlorophyll content, and vase life of cut flowers were investigated. Based on these data, it was analyzed for the correlation between cultivation environment, cropping system, and quality of cut flower elements. In correlation between cultivation environment and quality of cut flower, the average night temperature showed a negative correlation with the growth of cut flower, and it was no correlation with other environmental factors. The vase life showed a negative correlation with the average day and night temperature and VPD, and a most positive correlation with the average day and night humidity. In correlation between cropping system and quality of cut flower, the cutting length, period of vegetative growth, daily irrigation amount, and total irrigation amount showed a less positive correlation, and leaf number of cutting and soil pH showed a most positive correlation with growth of cut flower. On the other hand, soil EC showed a less negative correlation, and days to flowering after light out showed a most negative correlation with growth of cut flower. The vase life of cut flower was not correlated with the cropping system factors.
To evaluate the protective effect of Ajuga multiflora BUNGE (AMB) extract on the toxicity of lead acetate (LA), environmental pollutant, cell viability was measured by XTT assay using cultured NIH3T3 fibroblasts. And also, the effect of antioxidant, butylated hydroxytoluene (BHT) on LA-induced cytotoxicity was analysed. For the protective effect of AMB extract on LA-induced cytotoxicity, NIH3T3 fibroblasts were pretreated with 80 or 90 μg/mL of AMB extract for 2 hours before the treatment of LA. And also, the antioxidative effects of AMB extract against LA-induced cytotoxicity were assessed by DPPH-radical scavenging activity, superoxide dismutase (SOD)-like activity and inhibitory activity of lipid peroxidation (LP). In this study, LA significantly decreased cell viability dose-dependently compared with control, and then XTT50 value was determined at 46.1 μM of LA. In the effect of BHT against LA-induced cytotoxicity, it effectively prevented toxic effect of LA by the significant increase of cell viability. In the protective effect of AMB extract on LA-induced cytotoxicity, it significantly increased cell viability which was decreased by LA-induced cytotoxicity, and also it showed the antioxidative effects such as DPPH-radical scavenging activity, SOD-like activity and inhibitory activity of LP. From these results, it is suggested that the cytotoxicity of LA is involved in oxidative stress, and AMB extract effectively prevented the cytotoxicity induced by LA via an antioxidative effect. Conclusively, the natural substance such as AMB extract may be alternative resources for the prevention or treatment of diseases related with oxidative stress.
This study was conducted in order to examine the effects of horticultural activities and flower tea drinking based on reminiscent storytelling on demented elders’ cognitive and emotional functions. For these an purposes, the program was executed 35 elders divided four groups at the elders institutionalized at B Facility through 10 sessions during the period from 10 March to 14 July in 2015. As a result first, in the test of pretreatment homogeneity among the groups, no significant difference was observed among the four groups, so they were considered homogeneous. As to difference between before and after the program, cognitive functions were improved significantly after the treatment in the experimental group with both horticultural activities and flower tea drinking (p=.039). Among the emotional functions, self‐esteem was significantly different in the experimental group with only horticultural activities (p=.040), the experimental group with only flower tea drinking (p=.005), and the experimental group with both horticultural activities and flower tea drinking (p=.024). Life satisfaction was significantly different only in the experimental group with both horticultural activities and flower tea drinking (p=.005). Ego integrity was significantly different in the experimental group with only horticultural activities (p=.011) and the experimental group with both horticultural activities and flower tea drinking (p=.005). Therefore, the experimental group with both horticultural activities and flower tea drinking were improved significant that all the items of cognitive and emotional functions.
This study was conducted to analyze the muscle activity in the right forearm and shoulderwhile doing the sowing activity by muscle type and work section, and to find the possibility of the utilization of sowing as a muscle exercise and rehabilitative activity based on the results of the analysis. The results showed that the activity of 7 muscles including the upper trapezius near the neck, the upper trapezius near the shoulder, the middle deltoid, the biceps brachii, the triceps brachii, the brachioradialis, and the flexor carpi ulnaris were significantly higher than the stable state. In addition, the muscle activity in the sections of mixing the soil, filling the tray with the soil, sowing, writing the label, and watering was significantly higher than the stable state. In particular, the muscle activity of the biceps brachii and the triceps brachii was statistically significantly high in the section of filling the tray with the soil, which indicates that the task of filling the tray with the soil can be utilized as an exercise to activate the biceps brachii and the triceps brachii. In addition, the muscle activity of the brachioradialis was significantly high in all the work sections, which indicates that the sowing process can be utilized to exercise the brachioradialis in particular. These results can be used as the basic data about the activated muscle types and degrees throughout the sowing process. These results can be also used to induce the activation of specific muscles, and the overall exercise and rehabilitation of the forearms.
This study was taken place to find out the psychological change with comparing before and after the experience of installation of indoor garden with 55 of subjects out of 62 subjects. More than 50% of subject answered that the garden management would be difficult before they experience the installation but the pressure was decreased while the interest of plants and landscape increased, however, the burden of management decreased and the interest in the kinds of plants and landscape design tended to increase after the experience of the installation. The psychological effect of indoor garden of workers was significantly increased with the question of “Indoor garden improves effect of air cleaning.” after the experience of installation and the loyalty was statistically increased with the question of “Intend to invest more fund to purchase indoor plant” (p <.05). As a result of the comparison of two psychological indicators, the recovery index of the state according to experience of indoor gardening was significantly higher after experiencing the indoor garden than before the indoor gardening experience. As the result of sensibility evaluation of pleasant, natural and calm with semantic differential method, workers feel more of them with the indoor garden. In addition, the loyalty was statistically significantly higher in the question “I would be willing to invest more in plant purchase” after experiencing the composition indoor garden (p <.05). This result is similar to the result that the resident’s recovery index, pleasantness, calm feeling, and emotional index are higher the indoor garden in public resting area with indoor garden than without indoor garden. With this study, the perception of indoor garden changed as a result of the worker’s experience of indoor gardening in the workplace and the view of the indoor garden created by the workers. As the psychological healing effect of indoor garden increased, increase in the cost investment for the emotional health promotion of the workers is expected to have a positive effect on the increase of the indoor garden.
The purpose of this study was to investigate the motivation, healing purpose, healing process and healing effect of forest through experiential essays. These essays of 34 forest experience were collected from 2014 to 2015 at Forestry Administration Office. Five steps of analysis were used including self-observation, self-description, selfdiscovery, equality and differentiation, and verification. The results of the study are as follows. First, there were psychological instability factors such as depression, bipolar disorder, helplessness, social phobia, and social maladjustment, and these factors were related to physical illness or family history of patients. Second, the process of self-discovering by self-observation and self-description in forest experience was expressed, and this experience is interpreted to strongly support the effects of various forest healing proved empirically in previous studies. Third, the patients experienced similar sufferings such as depression, anxiety, and frustration, but they described as experiencing the process optimized for each unique characteristic in the motivation, necessity, accessibility, and program utilization of each experience. Ultimately, the participants felt positive change in senses and emotions such as refreshing, comfort, relaxation, and euphoria through the natural vitality of forests that is inhaled through the five senses. They learnt to reflect on themselves and shame, and they could rediscover the value and meaning of life while meaningfully recognizing the problems attributed to them.
The purpose of this study was to investigate the recognition and demands of forest interpretation programs. Questionnaire survey was carried out to estimate the awareness, necessity, future participation intent, experience, satisfaction and demands of forest interpretation programs with 100 residents living in Jinju city or Gyeongnam region. The data were subject to frequency analysis, correlation analysis, and path analysis. Overall 63% of respondents didn’t know forest interpretation programs, but 52% of respondents recognized the necessity of forest interpretation programs. 52% of respondents had the future participate intent of forest interpretation programs, and 38.3% didn’t know if they would participate. 74% of respondents had never experienced the programs. In the satisfaction, 80% of respondents who experienced showed neutral. Future participation intent was highly correlated with necessity as shown in the result of correlation analysis among awareness, necessity, future participation intent, and experience of forest interpretation programs. Also future participation intent in path analysis was estimated to be affected indirectly by experience and awareness as well as necessity. Enhancement of future participation intent would be achieved by increasing experience, awareness, and necessity of forest interpretation programs. According to the demands, forest interpreters were required to have the expertise to provide knowledge and information of forests. Attractive content for forest interpretation programs was in the order of recreational activities > forest conservation > education while the proper objective of forest interpretation programs was experience and interest > education > conservation and resource > public relation of forests and parks. Respondents preferred participation and experience the most as a style in selecting the programs. Key condition in selecting the venue was diversity > safety > connectivity > accessibility in order. There was no significantly different preference in proper participation duration or operation season for the activities of forest interpretation programs.
