When most middle-aged women live in a time when they have to take responsibility for their lives, they feel lonely when they realize that their experience of not expressing their feelings properly has ended up being left alone due to their own existence and loss. As the first step in conscious awareness of unconsciousness of middle-aged women through analytical psychology, we performed "Mandara" and "Nanhwa Mandara," which meet me inside. The intermediate stage can be divided into transition and work phase. The working phase, develops one's own advantages and unique strengths that meet the inner world of promoting and acting values, correctly looks at reality, corrects emotion perception and balance, and is self-contained, seed mandala, associative mandala. They performed the strong points of mandala, the free mandala, and the Western mandala. The results of the study showed that mandala art therapy was found in middle-aged women. First, Mandarin art therapy experience affects the physical, psychological and human relations aspects of middle-aged women. Second, middle-aged women's experience of individualization through mandala art therapy shows psychological reversals and affects positive thinking and self-effectiveness. This study was suitable for qualitative research that approached the essence through practical understanding and direct exploration of research participants, and it is meaningful to suggest that it is necessary to develop an art therapy program through various mediums considering the lack of art therapy research in middle-aged women and problems experienced by the physician.

Endophytes are microorganisms that live in the internal tissues of plants without harming the host plants. In this symbiotic relationship, the host plants provide nutrients and shelter to the endophytes, in turn, endophytes can promote the growth of host plants and act as a biological control agents against plant pathogens. Plant-microbe interactions like this are noted for natural methods for sustainable agriculture and environmental conservation. However, in spite of the infinite potential, there are only a few reports on the endophytes present in ginseng. In this study, we isolated and identified the endophytes from Panax ginseng seeds and evaluated the biological activities (IAA production ability, nitrogen fixation ability, phosphate solubilization capacity, siderophore production ability, and antifungal activities) of the endophyte isolates. Eight different endophytes were identified by 16S rRNA sequencing. Most of the endophytes have antibiotic and plant growth promoting (PGP) activities. Particularly, PgSEB5-37E have the highest antibiotic activity, both PgSEB5-37B and PgSEB5-37H have high PGP traits such as an abilities to produce IAA, solubilize phosphate and fix nitrogen. These results indicated that the endophytes from P. ginseng seeds may have applicable value to many industries. In order to use the isolated endophytes, quantitative analysis and field tests are needed to be performed.
Survival of biocontrol agents and their effective colonization of rhizhosphere are the essential components for successful disease suppression. The effects of hydrogel supplement on bacterial survival and disease control were evaluated in pot and in the field. Addition of 2% hydrogel material to potting soil resulted in significant enhancement of colonization of biocontrol agent Serratia plymuthica A21-4 both in soil and rhizosphere of pepper plants. Rhizosphere colonization of S. plymuthica A21-4 retrieved from 40 days old pepper seedlings indicated 100 times higher bacterial population in hydrogel treated soil than in ordinary pot soil. The pepper plants sown in hydrogelated potting soil showed higher seed germination rate and the better growth of pepper plant than those in ordinary commercial pot soil. Although the suppression of Phytophthora capsid density in the potting soil by treatment of biocontrol agent A21-4 was not significantly different between in hydrogelated soil and ordinary potting soil, the suppression of Phytophthora blight between two treatments was significantly different. A21-4 treatment in hydrogelated potting soil was completely disease-free while same treatment in ordinary potting soil revealed 36% disease incidence. Our field study under natural disease occurrence also showed significantly less disease incidence(12.3%) in the A21-4 treatment in the hydrogelated soil compared to other treatments. Yield promotion of pepper by the A21-4 treatment in the hydrogelated potting soil was also recognized. Our results indicated that hydrogel amendment with biocontrol agent in pot soil would be a good alternative to protect pepper seedlings and increase plant yield.
An auxin-producing bacterium, Klebsiella michiganensis Jopap-1, was isolated from a button mushroom bed in Buyeo-Gun, Chungcheongnam-Do. The strain Jopap-1 was classified as a novel strain of K. michiganensis based on a chemotaxonomic and phylogenetic analysis. The isolated K. michiganensis Jopap-1 was confirmed to produce indole-3-acetic acid (IAA), which is one of auxin hormones by TLC and HPLC analyses. The maximum concentration of IAA ($96.05mg\;L^{-1}$) was detected in the culture broth incubated in R2A medium containing 0.1% L-tryptophan for 48 h at $35^{\circ}C$ by HPLC quantity analysis. A negative relationship between IAA production and pH variation was estimated to show that the increase of IAA caused acidic pH in the culture. The effect of the supplement on L-tryptophan (precursor of IAA) production was observed to be highest at 0.1% concentration, but was significantly lowered above a concentration of 0.2%. To investigate the growth-promoting effects on the crops, the culture broth of E. michiganensis Jopap-1 was infected to water cultures and seed pots of mung bean and lettuce. Consequently, the adventitious root induction and root growth of mung bean and lettuce were observed to be 2.1 and 1.8 times higher than those of the control.

Maintenance of a beneficial microbial community, especially in the rhizosphere, is indispensable for plant growth and agricultural sustainability. In this sense, plant growth-promoting rhizobacteria (PGPR) have been extensively studied for their role in plant growth promotion and disease resistance. However, the impact of introducing PGPR strains into rhizosphere microbial communities is still underexplored. We previously found that the Proteus vulgaris JBLS202 strain (JBLS202) promoted growth of Kimchi cabbage and altered the relative abundance of total bacteria and Pseudomonas spp. in the treated rhizosphere. To extend these findings, we used pyrosequencing to analyze the changes in bacterial communities in the rhizosphere of Kimchi cabbage after introduction of JBLS202. The alterations were also evaluated by taxon-specific realtime PCR (qPCR). The pyrosequencing data revealed an increase in total bacteria abundance, including specific groups such as Proteobacteria, Acidobacteria, and Actinobacteria, in the treated rhizosphere. Time-course qPCR analysis confirmed the increase in the abundance of Acidobacteria, Actinobacteria, Alphaproteobacteria, and Betaproteobacteria. Furthermore, genes involved in nitrogen cycling were upregulated by JBLS202 treatment indicating changes in ecological function of the rhizosphere soil. Overall, these results indicate that introduction of JBLS202 alters both the composition and function of the rhizosphere bacterial community, which can have direct and indirect effects on plant growth. Therefore, we propose that long-term changes in bacterial composition and community-level function need to be considered for practical use of PGPRs.

This study was carried out to investigate the influence of artificial acid rain on the growth of soybean irradiated with the low dose gamma radiation. The growth patterns of Hwangkumkong and Bangsakong were not dependent on the acid rain treatment and the period of seed storage but the radiation dose. In Hwangkumkong, the optimal irradiation dose for the growth promotion was lower in the acid rain treatment group than the control group. The symptom of acid rain damage appeared broadly around pH 2.20, were higher in Hwangkumkong than in Bangsakong, and were more effective in the seeds of 1997 than 1995. But the damage symptom of Bangsakong was not dependent on the acid rain treatment and the irradiation of gamma radiaiton.
With both common and Tartary buckwheat species, this study was aimed at producing new commercially useful bio-materials with higher nutritional and medicinal value due to higher components for health promotion and diseases care. In common buckwheat sprouts, it was found that root length at $20^{\circ}C$ was longer (5.93 cm) than at 25 and $30^{\circ}C$, whereas the hypocotyls length, fresh weight of each sprout, and whole fresh weight showed the highest value at $30^{\circ}C$. For Tartary buckwheat, the root length, hypocotyl length and fresh weight of each sprout and whole fresh weight were also the highest at $30^{\circ}C$. Common buckwheat (Suwon No.1) and Tartary buckwheat (KW45) sprouts cultured at $20^{\circ}C$ showed that hypocotyl length, fresh weight of each sprout, and whole fresh weight in the control were higher than those sprouts treated with 5% and 10% deep sea water (DSW), while the sprouts cultured at $30^{\circ}C$ showed were significantly longer hypocotyls than the control or 5% DSW treatment.
Bacteria from the Methylobacterium genus, called pink-pigmented facultative methylotrophic bacteria (PPFMs), are common inhabitants of plants, potentially dominating the phyllosphere population, and are also encountered in the rhizosphere, seeds, and other parts of plants, being versatile in nature. The consistent success of the Methylobacterium plant association relies on methylotrophy, the ability to utilize the one-carbon compound methanol emitted by plants. However, the efficiency of Methylobacterium in plant growth promotion could be better exploited and thus has attracted increasing interest in recent years. Accordingly, the present study investigated the inoculation effects of Methylobacterium sp. strains CBMB20 and CBMB 110 on seed imbibition to tomato and red pepper on the growth and accumulation of phytohormone levels under gnotobiotic conditions. Seeds treated with the Methylobacterium strains showed a significant increase in root length when compared with either the uninoculated control or Methylobacterium extorquens $miaA^-$ knockout mutanttreated seeds. Extracts of the plant samples were used for indole-3-acetic acid (IAA), trans-zeatin riboside (t-ZR), and dihydrozeatin riboside (DHZR) assays by immunoanalysis. The treatment with Methylobacterium sp. CBMB20 or CBMB 110 produced significant increases in the accumulation of IAA and the cytokinins t-ZR and DHZR in the red pepper extracts, whereas no IAA was detected in the tomato extracts, although the cytokinin concentrations were significantly increased. Therefore, this study proved that the versatility of Methylobacterium as a plant-growth promoting bacteria could be better exploited.

This thesis discusses a performer's unpredictability and immediacy as a prerequisite quality and/or ability to facilitate his/her professional identity as a doer on stage. To examine the key principles and approaches, this research focuses on addressing a specific aspect of the performer's transformative experience from those, directors, and practitioners' concepts that inform and enhance the performer's passive readiness on stage. To be precise, this research attempt to interrogate and articulate the place and role of a performer's internal readiness and/or that of inner looking. The performer's inner intensity as seed of action signifies that his/her body is being in a state of listening to every tiny moment with his/her heightened awareness which in turn lead the performer's body to meet the demands of theatre, the whole-body engagement. Here, this thesis argues that the key principles of acting/training underlies the importance of a performer's ethical attitude and at the same time his/her responsibility for what the performer's choices and experiences within the performative involvement, that is, a process of preparation, are not technical matter but rather, the concepts, and/or approaches from those theatre artists' practical assumptions highlight a process of thorough encountering and/or listening to his/her body. Inhabiting and/or obtaining the principles through the performer's body means being free from his/her unnecessary trait(s) which in turn initiate and then move the whole body according to what is happening in the series of moment(s) on stage. What is more, such an appropriate psychophysical order reminds us of the significance of the nature of human/performer's body, namely, to being in a state of one's 'own' body as oneness. From this perspective, this thesis further argues that the performer's body necessarily need to be affected and/or triggered in a sense of responding to the given circumstance where the performer is working on in the here and now.

The effect of sodium hypochlorite treatment on the germination of cattail (Typha spp.) seeds was investigated in growth chambers maintained on a 14-h photoperiod with various temperatures and light intensities. Germination rates of seeds were, in general, enhanced by the increase of light intensity and temperature regardless of cattail species. Seeds of T. oreientalis had 4.3, 13.0 and $7.3\%$ germination at temperatures of 20, 25 and $30^{circ}$C, respectively, under light intensity of 7.5${\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$. T. angustata showed higher germination rate, thus, 10.7, 22.7 and $50.7\%$ under same temperature and light environment. Under high light intensity of 79.5${\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$, the germination rates of T. oreintalis and T angustata were $78.3\%$ and $88.7\%$ at $30^{circ}$C, respectively. Scarification of seeds with NaOC1 ($4\%$, available chlorine) increased germination rate in both species, especially even at low temperature of $20^{circ}$C. Germination speed was also enhanced by NaOC1 treatment. High light intensity further increased the germination rate. When NaOC1 treated seeds were sowed on the soil surface in plastic house, the seedling emergence was nearly $100\%$. Untreated seeds of T. oreintalis and T. angustara showed 40 and $50\%$, respectively, in germination under same condition. However, when the depth of soil covering was over 1.0 cm, seedling emergence was retarded more than 1 month. On the process of seedling development, emergence of mesocoty1 occurred firstly and after than primary root and first leaf were developed on the end of elongated mesocotyl. These results suggest that the promotion of seed germination by NaOC1 pretreament may be induced from the increase of light absorptivity as well as water permeability through scarifying and bleaching the seed coat.
