Purpose: The purpose of this study is to identify the health promoting lifestyle and need assessment of a health promotion program. and to develop a health promotion program for rural elderly. Method: The subjects of the study were 366 adults chosen from 24 villages located in Geochang Gun, Korea. Data sampling used a quota sampling method. Analysis of the data was done by using descriptive statistics, t test, ANOVA and the Scheffe test with SPSS. Results: 1) The average score of performance in the health promoting lifestyle was 1.85. In the subscales, the highest degree of performance was 'nutrition', followed by 'interpersonal relationships', 'health responsibility', 'stress management', 'spiritual growth', and the lowest degree of performance was 'physical activity'. 2) Health promoting lifestyles were significantly correlated with such demographic variables as age (F=2.684, p=.047), education (F=10.989, p=.000), monthly pocket money (F=3.516, p=.008), religion (F=7.160, p=.000), current health status F=3.375, p=.035), health education (t=2.476, p=.014). 3) Health promoting lifestyles were significantly correlated with such life style pattern variables as milk drinking (F=3.767, p=0.035), hobbies (t=3.072, p=0.002), exercise (t=7.186, p=0.000). 4) There is a high level of need for the need assesment of the health promotion program for the elderly in the rural area. Conclusion: With the above findings. I propose that it is necessary to understand a health promoting lifestyle and need assessment for a health promotion program, and to develop a health promotion program considering regional and environmental elements.

The purpose of this study is to investigate the level of verbal abuse experiences, emotional labor, and health-promoting behaviors of nurses in small and medium hospitals and to identify the relationship between them. Participants were 138 nurses from 2 small-medium sized hospitals. Collected data were analyzed using t-test, ANOVA, and Pearson's correlation coefficients with the SPSS 20.0 for Windows Program. As a result of the study, 82.7% of them experienced verbal abuse, and there were differences in the degree of health- promoting behavior according to gender (p=.032) and department (p=.009). Besides, it was found that emotional labor was related to health-promoting behavior (p=.039), and spiritual growth (p=<.01), and stress management (p=.028) as sub-factors. Accordingly, this study will be used as basic data for developing strategies and customized programs to reduce emotional labor, increase health-promoting activities, and contribute to the stable securing of nursing personnel.

This study examined the effects of different photoperiod conditions on olive flounder (Paralichthys olivaceus), a commercially important species in Korea. Daily variations in the expression of mRNA for the growth-related genes arylalkylamine N-acetyltransferase2 (AANAT2), preprosomatostatin1 (PSS1), and growth hormone (GH) were examined under a 12 h light:12 h dark photoperiod. All the genes were expressed at higher level during the dark period. Melatonin injections increased the expression of GH, but did not significantly affect the expression of PSS. Under short-day conditions (10 h:14 h), the fish gained more weight than under long-day conditions (14 h:10 h). A long nighttime induced melatonin secretion and increased the expression of GH mRNA, promoting weight gain in this species. Therefore, we thought that the long day condition in raising olive flounder may be effective in inducing body growth.

This study was conducted to determine the effect of treatment with the plant-growth-promoting bacteria on the growth and yield of red pepper(Capsicum annuum L.) with different soil electrical conductivity(EC) levels. The mixed liquid culture was done pseudomonas P and saboraud dextrose medium. The isolated bacteria(IB) were inoculated by spray of 3.7ml at 1/2000a pot filled with different soil electrical conductivity level(2.9, 8.6, 11.5dS/m) every week, respectively, with mixed liquid culture (Pseudomonas P+Sabouraud dextrose) of eight strains. The plant height of red pepper with IBs treatment in different soil EC levels showed better growth than IBs nontreatment in the order of the 2.9>8.6>11.5 dS/m. The yield of pepper with IBs treatment in different soil EC level was higher in 13% than IBs nontreatment and chemical properties($P_2O_5$, K, Ca, Mg) of the soil after harvest in IBs treatment were slightly increased, while organic matter and EC of IBs treatment were slightly decreased than those of IBs nontreatment. Moisture content of the soil after the harvesting with IBs treatment was slightly increased than IBs nontreatment.

It is commonly believed that black soybean (Glycine max: BB) prevents and alleviates hair loss. However, few studies have directly assessed the effect of BB on hair growth. We presently evaluated the mitosis induction on dermal papillae cell and mitogenic effect on NIH3T3 cells in vitro. To elucidate the hair growth promoting effect in vivo, anagen induction and hair restoration were examined in a shaving model of C57BL/6 mice. We also conducted biochemical analysis of blood plasma. Significant stimulation of dermal papillae and NIH3T3 cell proliferation were observed by treatment of BB in a dose-dependent manner. BB markedly promoted hair growth and significantly improved blood total antioxidant capacity and reduced lipid peroxidation and triglyceride level. These results suggest that BB has hair growth promoting effect and it is a potent candidate for the prevention of hair loss.

This study aims to assess the development effectiveness of the Paris Declaration (2005). Using data collected by the OECD/DAC from 78 developing countries for the period 2005~2010, this study evaluates the role played by the Paris Declaration principles alone and in interaction with aid in promoting per-capita GDP growth. The analysis shows that the overall net impact of aid on promoting economic growth has been negative. However, aid effectiveness has been enhanced by the sound policies or institutions and some Paris Declaration (PD) principles. Of the five principles of the PD, only the alignment and, to some extent, mutual accountability principles of the PD did show a significant and positive role in making aid more effective for economic growth of aid recipient countries. Therefore, OECD's statement that the PD enhances aid effectiveness is supported only partially. These findings have significant implications for the importance accorded to sound policies and institutions in the growth literature, and for future international development cooperation agenda.

The objective of this study was to determine the effect of single and co-inoculation of plant growth promoting bacteria (PGPB) on early plant growth in Saemangeum reclaimed soil. Plant growth promoting Brevibacterium iodinum RS16 and Methylobacterium oryzae CBMB20 were inoculated on maize (Zea mays L.) and sorghum-sudangrass hybrid (Sorghum bicolor L.) grown in Saemangeum reclaimed soil. Single and co-inoculation of B. iodinum RS16 and M. oryzae CBMB20 increased plant height, dry biomass accumulation and macro-nutrient accumulation of maize and sorghum-sudangrass hybrid. M. oryzae CBMB20 treatment increased plant height in maize by 41.2% at 30 days after sowing (DAS), shoot dry weight and total dry weight compared to non-inoculated treatment. Macro-nutrient accumulation (N and P) in maize roots was significantly increased with co-inoculation treatment, K and Ca content was significantly increased at B. iodinum RS16 treatment compared to non-inoculated treatment. Macro-nutrient accumulation (P, K, Ca and Mg) in shoot was higher with M. oryzae CBMB20 treatment compared to non-inoculated treatment. In case of sorghum-sudangrass hybrid, co-inoculation treatment showed 33.7% increase in plant height compared to non-inoculated treatment at 30 DAS. M. oryzae CBMB20 treatment increased root dry weight and total dry weight, macro-nutrient accumulation in roots and N, Ca and Mg accumulation in shoot compared to non-inoculated treatment. P and K accumulation in shoot was significantly increased at co-inoculation treatment compared to non-inoculated treatment. This pot culture experiment demonstrated that single and co-inoculation of B. iodinum RS16 and M. oryzae CBMB20 increased the early growth and nutrient accumulation of maize and sorghum-sudangrass hybrid.

We investigated influence of three commercial antibiotics viz., oxolinic acid, streptomycin, and validamycin A, on biocontrol and plant growth promoting activities of Bacillus vallismortis EXTN-1 and BS07M in Chinese cabbage. Plants were pre-drenched with these strains followed by antibiotics application at recommended and ten-fold diluted concentration to test the effect on biocontrol ability against soft rot caused by Pectobacterium carotovorum SCC1. The viability of the two biocontrol strains and bacterial pathogen SCC1 was significantly reduced by oxolinic acid and streptomycin in vitro assay, but not by validamycin A. In plant trials, strains EXTN-1 and BS07M controlled soft rot in Chinese cabbage, and there was a significant difference in disease severity when the antibiotics were applied to the plants drenched with the two biocontrol agents. Additional foliar applications of oxolinic acid and streptomycin reduced the disease irrespective of pre-drench treatment of the PGPRs. However, when the plants were pre-drenched with EXTN-1 followed by spray of validamycin A at recommended concentration, soft rot significantly reduced compared to untreated control. Similarly, strains EXTN-1 and BS07M significantly enhanced plant growth, but it did not show synergistic effect with additional spray of antibiotics. Populations of the EXTN-1 or BS07M in the rhizosphere of plants sprayed with antibiotics were significantly affected as compared to control. Taken together, our results suggest that the three antibiotics used for soft rot control in Chinese cabbage could affect bacterial mediated biocontrol and plant growth promoting activities. Therefore, combined treatment of the PGPRs and the commercial antibiotics should be carefully applied to sustain environmental friendly disease management.

Plant growth-promoting rhizobacteria (PGPR) have the potential to be used as microbial inoculants to reduce disease incidence and severity and to increase crop yield. Some of the PGPR have been reported to be able to enter plant tissues and establish endophytic populations. Here, we demonstrated an approach to screen bacterial endophytes that have the capacity to promote the growth of pepper seedlings and protect pepper plants against a bacterial pathogen. Initially, out of 150 bacterial isolates collected from healthy stems of peppers cultivated in the Chungcheong and Gyeongsang provinces of Korea, 23 putative endophytic isolates that were considered to be predominating and representative of each pepper sample were selected. By phenotypic characterization and partial 16S rDNA sequence analysis, the isolates were identified as species of Ochrobacterium, Pantoea, Pseudomonas, Sphingomonas, Janthinobacterium, Ralstonia, Arthrobacter, Clavibacter, Sporosarcina, Acidovorax, and Brevundimonas. Among them, two isolates, PS4 and PS27, were selected because they showed consistent colonizing capacity in pepper stems at the levels of $10^6-10^7CFU/g$ tissue, and were found to be most closely related to Pseudomonas rhodesiae and Pantoea ananatis, respectively, by additional analyses of their entire 16S rDNA sequences. Drenching application of the two strains on the pepper seedlings promoted significant growth of peppers, enhancing their root fresh weight by 73.9% and 41.5%, respectively. The two strains also elicited induced systemic resistance of plants against Xanthomonas axonopodis pv. vesicatoria.

Plant growth promoting fungi (PGPF) are well known for the production of useful secondary metabolites. However, limited information is available on the gibberellin (GA) production capacity of PGPF of endophytic origin. In the current study, 15 fungal endophytes were isolated from the roots of Crown daisy, and then screened on Waito-c rice, in order to identify plant growth promoting fungi. The fungal isolate MH7 significantly increased the shoot length (12.1 cm) of Waito-c in comparison with control treatment (7.9 cm). In a separate experiment, the culture filtrate (CF) of MH7 significantly promoted the growth attributes of Crown daisy. The MH7 CF was analyzed for gibberellins and it contained all physiologically active gibberellins ($GA_1$, 1.37 ng/ml; $GA_3$, 5.88 ng/ml; $GA_4$, 8.62 ng/ml; and $GA_7$, 2.05 ng/ml) in conjunction with physiologically inactive $GA_9$ (0.83 ng/ml), $GA_{12}$ (0.44 ng/ml), $GA_{15}$ (0.74 ng/ml), $GA_{19}$ (1.16 ng/ml), and $GA_{20}$ (0.98 ng/ml). The CF of MH7 produced higher amounts of $GA_3$, $GA_4$, $GA_7$, $GA_9$, and $GA_{12}$ than wild-type Fusarium fujikuroi, which was used as a control for GA production. The fungal isolate MH7 was later identified as a new strain of Penicillium on the basis of its morphological characteristics and phylogenetic analysis of the 188 rDNA sequence.
