This study assessed the possible role of different traits in selected plant growth-promoting rhizobacteria (PGPR) for improving wheat growth and yield under natural conditions. Rhizobacteria exhibiting 1-aminocyclopropane-1-carboxylate (ACC)-deaminase activity were isolated and screened for their growth-promoting activity in wheat under axenic conditions. Five isolates belonging to Pseudomonas and one Burkholderia caryophylli isolate that showed promising performances under axenic conditions were selected and characterized for in vitro ACC-deaminase activity, chitinase activity, auxin production, P solubilization, and root colonization. These isolates were then used as inocula for wheat cultivated under natural conditions in pot and/or field trials. Significant increases in root elongation, root weight, tillers per pot, 1,000-grain weight, and grain and straw yields were observed in response to inoculation with PGPR in the pot trials. Inoculation with these PGPR was also effective under field conditions and increased the wheat growth and yield significantly. However, the efficacy of the strains was inconsistent under the axenic, pot, and field conditions. Pseudomonas fluorescens ($ACC_{50}$), which exhibited a relatively high in vitro ACC-deaminase activity, chitinase activity, auxin production, and P solubilization and more intensive root colonization, was the most efficient isolate under the field conditions. Therefore, these results demonstrated that ACC-deaminase activity is an efficient parameter for the selection of promising PGPR under axenic conditions. However, additional traits of PGPR, including auxin production, chitinase activity, P solubilization, and root colonization, are also important for selecting PGPR as biofertilizers.

This study was a descriptive study to identify the effect of health promoting behavior on fatigue and depression and to investigate these levels among nurses. Data were collected from September 19th 2012 to September 25th 2012 by questionnaires from 243 hospital nurses of 3 hospitals in Kyungsang-Bukdo. The data was analyzed using descriptive statistics, t-test, Pearson's correlation coefficients, ANCOVA, and Stepwise multiple regression. The result showed that in health promoting behavior, shift nurses had higher scores than it of non-shift nurses. The health promotion behavior predictors of fatigue were spiritual growth and stress management and the predictors of depression were physical activity and interpersonal relationship. This results suggest that development of professional health promoting program which is strengthened these parts of spiritual growth, stress management, physical activity and interpersonal relationship, is needed.

The purpose of this study is to improve library promotional marketing for the disabled by identifying requirements of public library disability services. This study aimed to investigate librarian service providers' awareness of library programs for the disabled in order to prepare a systematic plan for promoting such library services. Research methods used are a literature analysis and survey. First, the ratio of respondents with experience promoting activities and services for the disabled was less than 50%. Second, regarding methods for promoting library disability services, the respondents used library homepages, press releases, library user guides, library newsletters, and library pamphlets in that order. Third, when asked what kind of PR media the library disability service providers had experience with and how often they use it, library boards and banners were the most common response. Fourth, suggested improvements to the current design and content of PR materials included: clearer word choice (or greater understandability), more detailed descriptions, simpler layouts, and more interesting or eye-catching content in that order. Fifth, the library disability services which are in the most need of public relations were guide information for library disability services, Library and Information Service (DOI services and search services), using alternative materials and the library collection, and aiding the information search. Overall, when evaluating the promotion of disability services in Korea, the library's public relations for disabled services needs to improve because currently neither librarians nor the disabled community they are targeting has frequent or quality experience with it. Thus, the policy department for the library disability services must develop a variety of promotional strategies adjusted for each type of the disability and distribute PR materials to service providers individually, making sure to utilize effective PR methods.

In the present study, we demonstrate that the growth of salt-stressed pepper plants is improved by inoculation with plant growth-promoting rhizobacteria (PGPR). Three PGPR strains (Microbacterium oleivorans KNUC7074, Brevibacterium iodinum KNUC7183, and Rhizobium massiliae KNUC7586) were isolated from the rhizosphere of pepper plants growing in saline soil, and pepper plants inoculated with these PGPR strains exhibited significantly greater plant height, fresh weight, dry weight, and total chlorophyll content than non-inoculated plants. In addition, salt-stressed pepper plants that were inoculated with B. iodinum KNUC7183 and R. massiliae KNUC7586 possessed significantly different total soluble sugar and proline contents from non-inoculated controls, and the activity of several antioxidant enzymes (ascorbate peroxidase, guaiacol peroxidase, and catalase) was also elevated in PGPR-treated plants under salt stress. Overall, these results suggest that the inoculation of pepper plants with M. oleivorans KNUC7074, B. iodinum KNUC7183, and R. massiliae KNUC7586 can alleviate the harmful effects of salt stress on plant growth.

Aquatic plant Hydrocharis dubia (Blume) Backer was collected from the Dalsung wetland in Daegu. Sixteen endophytic fungi with different colony morphologies were isolated from the roots of aquatic plants. Waito-c rice (WR) seedlings were treated with fungal culture filtrates (FCF) for screening plant growth-promoting activity. In the results, HD1008 strain isolated from aquatic plant showed highest plant growth-promoting activity. The FCF of HD1008 strain was analyzed using gas chromatography mass spectrometry (GC/MS) with selected ion monitoring (SIM). Analysis of the FCF of HD1008 strain found that it contained gibberellins (GA) ($GA_1$, 1.2 ng/100 mL; $GA_4$, 5 ng/100 mL). Phylogenetic tree of HD1008 strain was constructed by partial internal transcribed spacer (ITS) region and partial beta-tubulin gene sequences. Therefore, we describe HD1008 strain as a new gibberellin-producing Penicillium trzebinskii based on morphological and molecular characteristics.

This Meta-Analysis of 18 studies was conducted to determine the magnitude of th relationship between health promotion behavior and each of explanatory variables. The studies were measured using Health Promoting Life Style(HPLP) developed by Walker and others based on Pender's definiton of health promoting behavior. The sample was collected by searching for The Journal of Korean Academy Nursing Society, The Journal of Korean Women's Health Nursing Academic Society,The Journal of Korean Academic Society of Adult Nursing, Journal of Korean Community Nursing, The Journal of Fundamentals of Nursing, The Journal of Korean Nursing Administration Academic Society, The Korean Journal of Child Health Nursing, The Journal of Korean Psychiatric Academic Society, the dissertations for mater degree or doctoral dissertations for the period from 1980 to 1998. The explanatory variables measured more than 2 times in studies were self-efficacy, perceived health status, self-esteem, internal, powerful-others and chance dimensions of health locus of control, perceived benefits, hardiness, wellbeing and clinical demensions of health concepts, and quality of life(life satisfaction). Effect sizes were calculated by unweighted mean r, weighted mean r by sample size and weighted mean r by quality index score after homogeneity test. The mean r effect size indicator range of each predictor variable were as follows; quality of life (0.50- 0.52), self-efficacy (0.46-0.47), hardiness (0.42-0.44), self-esteem(0.41-0.43), health locus of control- internal(0.32-0.34), health locus of control- powerful others (0.25-0.31), perceived health status(0.18-0.19) and clinical dimensions of health concepts (0.16-0.17).

The possible tumor-promoting activities of sodium chloride (NaCl) and dimethyl itaconate (DMI), one of the quinone reductase inducers, were examined on stomach of male Wistar rats treated with N-methyl-N'-nitro-N-nitrosoguanidine (MNNG). Administrations of NaCl and DMI after the initiation by MNNG resulted in various sized masses in the rat forestomach. Histopathologic studies showed that the combination of NaCl and DMI made an enhancing effect on the MNNG-induced carcinogenesis, resulting in papilloma in 5 weeks and squamous cell carcinoma in 20 weeks in submucosal area of forestomach. We also used an in vivo shortterm method for evaluating possible tumor-promoting activity with ornithine decarboxylase (ODC) as a marker. The markable inductions of the ODC activities by MNNG, NaCl, and DMI were found in the pyloric mucosa of rat stomach in time-dependent manners. A single administration of MNNG induced ODC activity up to 288 pmol $CO_2$/hr/mg protein at 24 hr after the administration. NaCl caused induction of ODC with a maximum of 179 pmol $CO_2$/hr/mg protein at 8 hr after the administration. ODC was induced up to 539 pmol $CO_2$/hr/mg protein at 16 hr after the administration of DMI. Additional treatment of NaCl and NaCl plus DMl caused 2 fold and 7 fold increases, respectively, in the ODC activity of the MNNG-alone group at 24 hr after the administration. These results suggest that NaCl and DMI have promoting activities in the rat gastric carcinogenesis initiated by MNNG.

Objectives: The objectives of this study were to assess the implementation status of Health Promoting Schools (HPS) among elementary, middle and high schools and to identify characteristics of the schools that affect the implementation of HPS. Methods: A total of 703 teachers (male 32.2%, females 67.8%) from 70 elementary, middle and high schools in Seoul and Gyeonggi participated in the survey. A 60-item self-evaluation questionnaire was used to assess implementation status of HPS. Results: Implementation of HPS in elementary schools were more favorable than middle and high schools after controling for participants' characteristics, such as age, gender, and their duties at school (<0.001). Being a private school was associated with higher score on implementation of HPS in both elementary (${\beta}$=0.170) and middle/high schools (${\beta}$=0.275). However, being located in rural areas (${\beta}$=-0.409) and having larger number of students (${\beta}$=-0.521) were associated with lower score on implementation of HPS in middle/high schools. Conclusions: Middle and high schools, especially large public and/or rural schools, were less favorable in implementing HPS. Therefore, supporting those schools are necessary and developing evaluation and monitoring system for HPS implementation will contribute to promote students' health.
