Objectives: The purpose of this study was to provide basic data to develop a future health promotion program through the comparison of health promoting behavior and perceived health status between Koreans and Korean-Americans. Methods: The subjects of this study were 411 adults recruited from religious organizations located in the Yongnam area, Korea, and Chicago, U.S.A. The instruments used in the study were Health Promoting Lifestyle Profile II (HPLP) developed by Walker, Sechrist & Pender (1995), and the Health Self Rating Scale designed by North Illinois University. The data were analyzed using descriptive statistics, Pearson correlation coefficient, ANCOVA, ANOVA and Duncan test with the SPSS program. Results: 1) The mean HPLP score was 2.26 in Koreans and 2.43 in Korean-Americans, showing a significant difference between the two groups. 2) In subscales of HPLP, both groups showed the highest practices in 'interpersonal relationship' and the lowest practices in 'physical activity'. 3) The mean score of perceived health status was 2.26 in Koreans and 2.43 in Korean-Americans, showing a significant difference between the two groups. 4) Health promoting behavior was significantly different by family income in Koreans, but significantly different by age and family income in Korean-Americans. 5) Perceived health status was significantly different by family income and marital status, but significantly different by age, education, and family income. 6) The HPLP was not correlated with perceived health status in Koreans, but positively correlated with perceived health status in Korean-Americans. Conclusion: The study findings suggest a need to develop a health promotion program, in which physical activity and stress management for Koreans and Korean-Americans are emphasized, and cultural and environmental elements are considered, for better understanding of their health related issues.

Growth promotion of wild plants by some plant growth-promoting rhizobacteria (PGPR) was examined in the microcosms composed of soils collected separately from a grass-covered site and a nongrass-covered site in a lakeside barren area at Lake Paro, Korea. After sowing the seeds of eight kinds of wild plants and inoculation of several strains of PGPR, the total bacterial number and microbial activity were measured during 5 months of study period, and the plant biomasses grown were compared at the end of the study. Acridine orange direct counts in the inoculated microcosms, $1.3-9.8{\times}10^9\;cells{\cdot}g\;soil^{-1}$ in the soil from the grass-covered area and $0.9-7.2{\times}10^9\;cells{\cdot}g\;soil^{-1}$ in the soil from the nongrass-covered site, were almost twice higher than those in the uninoculated microcosms. The number of Pseudomonas sp., well-known bacteria as PGPR, and the soil dehydrogenase activity were also higher in the inoculated soils than the uninoculated soils. The first germination of sowed seeds in the inoculated microcosm was 5 days earlier than the uninoculated microcosm. Average lengths of all plants grown during the study period were 26% and 29% longer in the inoculated microcosms starting with the grass-covered soil and the nongrass-covered soil, respectively, compared with those in the uninoculated microcosms. Dry weights of whole plants grown were 67-82% higher in the inoculated microcosms than the uninoculated microcosms. Microbial population and activity and growth promoting effect by PGPR were all higher in the soils collected from the grass-covered area than in the nongrass-covered area. The growth enhancement of wild plants seemed to occur by the activities of inoculated microorganisms, and this capability of PGPR may be utilized for rapid revegetation of some barren lands.

This study was carried out to investigate the plant growth promoting activity of hairy vetch (Vicia villosa Roth) on reclaimed land. At the previous research, Rhizobium sp. RH84 was isolated and selected for further study from hairy vetch. For the investigation of plant growth promoting effects by the Rhizobium sp. RH84, production of indole acetic acid (IAA), siderophore, phosphate solubilization and nitrogen fixation were tested and other characters were examined. As results, RH84 produced $9.03{\mu}g$ IAA per mL and showed nitrogen fixation activity. With the treatment of Rhizobium sp. RH84 to hairy vetch showed good growth at 0.3% salty reclaimed soil, and the production yield was increased up to 56% at field test. From these results, it was confirmed that the Rhizobium sp. RH84 would be used as a green manure for hairy vetch under the salty condition of reclaimed land.

The purpose of this study was to identify the effects of cognition promoting program on cognitive function, depression, and quality of life in elders. The participants were 1,251 who were above 60 years olds(averaging 76.9 years of age) without dementia. During 12 weeks they participated the cognitive health promoting program twice a week. The program consisted of ReBrain cognitive education and game program. Then the effects of treatment were compared using a paired t-test between pre-test and post-test. Cognitive function(t=-13.903, p<.001), depression(t=9.544, p<.001), and quality of life(t=-4.613, p<.001) in elderly were significantly different after 12-week. These findings indicate that an 12-week cognitive health promoting program could be an effective nursing intervention program to improve cognitive function, to decrease depression, and to promote quality of life in elders.

To investigate the effects of xylooligosaccharides on the in vitro growth of intestinal bacteria, various species were cultivated individually on the m-PYF medium containing a carbon source (0.5% w/v) such as xylooligosaccharides, isomaltooligosaccharides, fructooligosaccharides and sucrose, respectively. The health-promoting microorganisms such as Bifidobacterium bifidum, Bifidobacterium infantis, Bifidobacterium longum, Lactobacillus casei and Lactobacillus acidophilus grew more effectively by xylooligosaccharides than by other carbon source, though xylooligosaccharides inhibited the growth of Clostridium perfringens, Bacteroides fragilis, Escherichia coli, Staphylococcus aureus and Salmonella typhumurium. At the mixed culture xylooligosaccharides exerted a preferential stimulatory effects on numbers of the health-promoting microorganisms, while xylooligosaccharides inhibited populations of potential pathogens at relatively low level. Xylooligosaccharides also maintained the acidity of culture with Streptococcus mutans, caries-inducing bacteria, over pH 5.0. These results suggest that xylooligosaccharides selectively promote the growth of the health-promoting microorganisms in human intestine and prevent caries by inhibiting acid production from Streptococcu mutans.
