The purpose of this study was to determine the hair growth effects of lavender oil (LO) in female C57BL/6 mice. The experimental animals were divided into a normal group (N: saline), a vehicle control group (VC: jojoba oil), a positive control group (PC: 3% minoxidil), experimental group 1 (E1: 3% LO), and experimental group 2 (E2: 5% LO). Test compound solutions were topically applied to the backs of the mice ($100{\mu}L$ per application), once per day, 5 times a week, for 4 weeks. The changes in hair follicle number, dermal thickness, and hair follicle depth were observed in skin tissues stained with hematoxylin and eosin, and the number of mast cells was measured in the dermal and hypodermal layers stained with toluidine blue. PC, E1, and E2 groups showed a significantly increased number of hair follicles, deepened hair follicle depth, and thickened dermal layer, along with a significantly decreased number of mast cells compared to the N group. These results indicated that LO has a marked hair growth-promoting effect, as observed morphologically and histologically. There was no significant difference in the weight of the thymus among the groups. However, both absolute and relative weights of the spleen were significantly higher in the PC group than in the N, VC, E1, or E2 group at week 4. Thus, LO could be practically applied as a hair growth-promoting agent.

This experiment was conducted to determine the safety and feasibility of using compost-promoting-bacteria. Compost-promoting-bacteria was isolated from livestock compost containing sawdust. The isolated bacteria was identified as Bacillus subtilis LYH201 by the method of the composition of the fatty acid with MIDI system and Bergey's manual. This Bacillus subtilis LYH201 had the following characteristics : Gram-positive, straight rod ($0.5{\sim}0.7{\mu}m$ width, $2.5{\sim}3.0{\mu}m$ length), facultatively aerobic and product of xylanase, CMCase, catalase, oxidase, protease and $0.5{\sim}0.7{\mu}m$-amylase. Growth of Bacillus subtilis LYH201 at saccharose as carbon source(0.5%) was faster than other carbon source. Activity of cellulase. $0.5{\sim}0.7{\mu}m$-amylase and protease from Bacillus subtilis LYH201 after 24 hours at $50^{\circ}C$ by agar diffusion method was higher than that of low temperature. Optimum growth condition of Bacillus subtilis LYH201 was $50^{\circ}C$ and pH 6.

Plant growth-promoting effects of rhizobacterial inoculation obtained in pot experiments cannot always be dependably reproduced in fields. In this study, we investigated the effect of inoculation with Azospirillum brasilense and Methylobacterium oryzae, which have displayed growth promoting effects in several pot experiments, on growth and fruit yield of red pepper under field condition in a plastic-film house. Four rows spaced 90 cm apart were prepared after application of compost ($10Mg\;ha^{-1}$), and red pepper seedlings (Capsicum annum L., Nocgwang) were transplanted in each row with 40-cm space. Experimental treatments were consisted of A. brasilense CW903 inoculation, M. oryzae CBMB20 inoculation, and uninoculated control. Twelve plots, 10 plants per plot, were allotted to the three treatments with four replicates in a completely randomized design. At the time of transplanting, 50 mL of each inoculum ($1{\times}10^8cells\;mL^{-1}$) was introduced into root zone soil of each plant, and re-inoculated at 7 and 14 days after transplant. Plant growth and fruit yield were measured during the experiment. Both A. brasilense CW903 and M. oryzae CBMB20 could not promote growth of red pepper plants. All growth parameters measured were not significantly different among treatments. There were large variations in fruit yield recorded on plot basis, and no statistically significant differences were found among treatments. The failure to demonstrate the expected plant growth promoting effect of the inoculants is possibly due to various environmental factors, including weather and soil characteristics, reducing the possibility to express the potential of the inoculated bacterial strains.

Purpose: The purpose of this study is to examine the association of family support, self-efficacy, health literacy and perceived health status with health-promoting behavior (HPB) in married immigrant women. Methods: A cross-sectional based survey was conducted to collect data from married immigrant women living in Gyeongsang province. Questionnaires included Health promoting lifestyle profile II, General self - efficacy scale, Korean Health literacy assessment and perceived health status. Results: 157 subjects participated in the study (mean age, $30.47{\pm}6.83$). Their duration of living in Korea was $63.05{\pm}50.11$ months. Of the participants, 59.2% were Vietnamese. The level of HPB, perceived health status, health literacy, support of family and self-efficacy were $2.58{\pm}0.42$, $3.39{\pm}0.86$, $25.12{\pm}20.99$, $3.83{\pm}0.70$ and $3.61{\pm}0.53$ respectively. Factors affecting the HPB of the participants were support from family (${\beta}=.45$, p<.001) and self-efficacy (${\beta}=.16$, p<.05). The explanatory power of these two variables was 34.2%. Conclusion: This study suggests that the factors influencing the HPB of married immigrant women include support from family and self-efficacy. A variety of programs should be provided for families so that they can support those women to help them increase their HPB. It is recommended that more various programs be provided to increase their self- efficacy.

Various concentrations of ${\alpha}$-naphthalence acetic acid(NAA) as a root-promoting substance were tested in hardwood cutting of the mulberry(Morus bombycis Koidz., cultivar : Shinkwangppong) to make clear the callusing effect on the budding and root growth. Budding and shoot growth of cuttings were delayed at high concentrations of NAA within 10 days of callusing. Especially more severe is it at higher than 50ppm. More than 93% of them, however, budded in two weeks when callused at less than 100ppm NAA. Although rooting was accelerated at high concentration of NAA from the bigining of cutting, after that, rooting percentage increased to reach 100% in 35 days of cutting in any concentration except 150ppm with relatively low rooting. Root growth was utmostly accelerated at 50ppm NAA to show the highest amount in number, length and weight of roots per cutting although high concentration of it decreased mean root length.

This study analyzes appropriate government policy frameworks for promoting IPTV industry by studying the way of adoption and diffusion of IPTV services. Until recently, most researches on government policies for technology adoption have focused on the personal context. This research adopts two theories, i.e., innovation characteristics theory for personal context and implementation process theory for organizational context. It also hypothesizes that the innovation characteristics more influence on the behavioral intention for usage new media in the level of personal innovativeness is high. Moreover, in the level of expectancy for diffusion policy is high, the implementation of IPTV services more influences on the behavioral intention. The results by statistical analysis, it is found that the higher the level of personal innovativeness is, and the higher the level of expectancy for diffusion policy is, the more behavioral intention will be influenced by the characteristics of innovation and implementation of IPTV service. Thus it is important for government agencies to find the way to facilitate personal innovativeness as well as expectancy for diffusion policy.

Pseudomonas fluorescens GL20 is a plant growth-promoting rhizobacterium that produces a large amount of hydroxamate siderophore under iron-limited conditions. The strain GL20 considerably inhibited the spore germination and hyphal growth of a plant pathogenic fungus, Fusarium solani, when iron was limited, significantly suppressed the root-rot disease on beans caused by F. solani, and enhanced the plant growth. The mechanism for the beneficial effect of strain GL20 on the disease suppression was due to the siderophore production, evidenced by mutant strains derived from the strain. Analysis of the outer membrane protein profile revealed that the growth of strain GL20 induced the synthesis of specific iron-regulated outer membrane proteins with molecular masses of 85- and 90 kDa as the high-affinity receptors for the ferric siderophore. In addition, a cross-feeding assay revealed the presence of multiple inducible receptors for heterologous siderophores in the strain. In order to induce increased efficacy and potential in biological control of plant disease, a siderophore-overproducing mutant, GL20-S207, was prepared by NTG mutagenesis. The mutant GL20-S207 produced nearly 2.3 times more siderophore than the parent strain. In pot trials of beans with F. solani, the mutant increased plant growth up to 1.5 times compared with that of the parent strain. These results suggest that the plant growth-promoting P. fluorescens GL20 and the genetically bred P. fluorescens GL20-S207 can play an important role in the biological control of soil-borne plant diseases in the rhizosphere.

Bacterial strain BAS23 was isolated from rice field soil and identified as Bacillus amyloliquefaciens. Based on dual culture method results, the bacterium BAS23 exhibited potent in vitro inhibitory activity on mycelial growth against a broad range of dirty panicle fungal pathogens of rice (Curvularia lunata, Fusarium semitectum and Helminthosporium oryzae). Cell-free culture of BAS23 displayed a significant effect on germ tube elongation and mycelial growth. The highest dry weight reduction (%) values of C. lunata, H. oryzae and F. semitectum were 92.7%, 75.7%, and 68.9%, respectively. Analysis of electrospray ionization-mass spectrometry (ESI-MS) and $^1H$ nuclear magnetic resonance (NMR) spectroscopy revealed that the lipopeptides were iturin A with a C14 side chain (C14 iturinic acid), and a C15 side chain (C15 iturinic acid), which were produced by BAS23 when it was cultured in nutrient broth (NB) for 72 h at $30^{\circ}C$. BAS23, the efficient antagonistic bacterium, also possessed in vitro multiple traits for plant growth promotion and improved rice seedling growth. The results indicated that BAS23 represents a useful option either for biocontrol or as a plant growth-promoting agent.

The purpose of this study was to identify the health promotion behavior and its related factors of persons who wanted a comprehensive health check-up in order to provide a basis for health education to promote health enhancing behavior. Study variables were induced from Pender's Health Promotion Model. The subjects were 160 persons who had a check-up at the health promotion center in a university hospital in Tae-Gu, between September 8 and 22, 1998. The following instruments were used in the study : Lee Tae Wha's Health Promoting Life-style Profile, Park Chai soon's Self-efficacy Instrument and Moon Jeong Soon's Perceived Benefit and Barrier Instrument. Data was collected by self-reporting questionnaire. Analysis of the data was done by SAS program, t-test, ANOVA and Pearson-Correlation Coefficient. The results of this study were as follows. 1. The average score for the health-promotion behavior was 104.64. In the subcategories, self-actualization showed the highest degree of performance and physical exercise showed the lowest degree of performance. 2. In the relation of general characteristics of subjects to the level of health-promoting behavior, the male, the married, the group with several symptoms showed a high level of health-promoting behavior. 3. The relationship between the degree of performance in health-promotion behavior and its correlates were as follows: Self-efficacy was positively correlated to health promotion behavior, while the perceived barrier was correlated negatively. But the perceived benefit did not show a significant correlation with health promotion behavior. Results suggest that the development of programs with strategies to strengthen doing physical exercise and concerning health, increase self-efficacy and exclude the barriers to health promotion is recommended to individuals seeking a comprehensive health check-up.
