The inoculation of some microorganisms into a microcosm containing soil from a barren lakeside area at Lake Paro in Kangwon-do enhanced plant growth significantly. The direct and viable counts of soil bacteria and soil microbial activities measured by electron transport system assay and fluorescein diacetate hydrolysis assay were higher in inoculated soil. The plant growth promoting effect of this inoculation may be caused by phytohormone production and the solubilization of insoluble phosphates by the inoculated bacteria. Three inoculated strains of Pseudomonas fluorescens produced several plant growth promoting phytohormones, including indole-3-acetic acid (auxin), which was confirmed by thin layer chromatography and GC/MS. P. fluorescens strain B16 and M45 produced 502.4 and 206.1 mg/l of soluble phosphate from Ca3(PO4)2 and hydroxyapatite, respectively. Bacillus megaterium showed similar solubilization rates of insoluble phosphates to those of Pseudomonas spp. We believe that this plant growth promoting capability may be used for the rapid revegetation of barren or disturbed land.

Aluminium Foam Sandwich (AFS) panels are becoming always more attractive in transportation applications thanks to the excellent combination of mechanical properties, high strength and stiffness, with functional ones, thermo-acoustic isolation and vibration damping. These properties strongly depend on the density of the foam, the morphology of the pores, the type (open or closed cells) and the size of the gas bubbles enclosed in the solid material. In this paper, the vibrational performances of two classes of sandwich panels with an Alulight(R) foam core are studied. Experimental tests, in terms of frequency response function and modal analysis, are performed in order to investigate the effect of different percentage of porosity in the foam, as well as the effect of the random distribution of the gas bubbles. Experimental results are used as a reference for developing numerical models using finite element approach. Firstly, a sensitivity analysis is performed in order to obtain a limit-but-bounded dynamic response, modelling the foam core as a homogeneous one. The experimental-numerical correlation is evaluated in terms of natural frequencies and mode shapes. Afterwards, an update of the previous numerical model is presented, in which the core is not longer modelled as homogeneous. Mass and stiffness are randomly distributed in the core volume, exploring the space of the eigenvectors.

The purpose of this study was to test the effect of the health education on college students. The content of the health education was consisted of significance of health, smoking, alcohol use and sexuality, birth control, exercise and nutrition, chronic illness, contagious disease, stress management. Two groups non-equivalent to pre and post test quasi-experimental research design were used in this study. The total number of subjects were 174 college students who did not have a health related major. The experimental group attended this health education program for 16 weeks and the control group attended other liberal arts and science classes for 16 weeks. Data were analysed with the SPSS window program. The homogeneity between the experimental and the control group pretest data was tested by $X^2$ test and t-test. The differences in stress, self-esteem, general self-efficacy, locus of control and health promoting behaviors after the health education were tested with the repeated measure ANOVA. The results were as follows: 1. There was no significant difference in general characteristics, stress, self- esteem, general self-efficacy, locus of control and health promoting behaviors between the two groups before the health education. 2. There was a significant difference in stress(p= .000) and health promoting behavior (p= .000) between the two groups after the health education. 3. There was no significant difference in self-esteem(p= .531), self-efficacy(p= .110) and locus of control between the two groups after the health education. From the results above, it can be concluded that this health education for the college students was effective to relieve stress and improve health promoting behaviors. The above results suggest that repeated studies are needed for another college students and various health education programs should be developed to promote the health of the populace considering many health related concepts.

The purpose of this study is to inquire into the degree of health promotion activity in university students, and to find out the relationship between self-efficiency and health promotion behavior, Thus, we can offer basic data for developing an educational method or program for health promotion. For this research, data was collected from university men and women through a questionnaire from February 18 to March 20, 1998. A measuring instrument was based on lating reviews of health promotion behavior in chronic disease protection, perceived self efficiency, demographic factors, biological factors, and circumstatial factors. The content validity of the instrument was authenticated by two professors of nursing, and reliability was confirmed by 'cronbach' (${\alpha}^{\prime}$ after mortifying content through a pre-test on 30 students. 475 persons were analyzed in terms of average, percentage, t-test, ANOVA, Pearson's Correlation Coefficient, and Multiple Stepwise Regression by 'SPSS-PC'. The analyzed data is as follows: 1. Higher self-efficiency, as a cognitive-perceptual factor, has a beneficial effect on health promotion behavior (r=.479, p=.000). The result of analyzing the differences among a low group, a middle group, a high group in terms of self-efficiency reveals that the relationship between self-efficiency and health promoting behavior is meaningful. 2. The degree of health promoting behavior is 3.26 out of 6. Other figuresrelating to health promoting behavior, are as follows. self-actualization area (4.62), interpersonal area (4.60), stress management area (4.01), nutrition area (3.68), responsibility of health area (3.11), liquid and cigaret area (2.85), and exercise area (2.33). 3. The degree of self-efficiency was 6.81 out of 10. Other figures relating to self-efficiency are as follows. interpersonal area (7.89), self-actualization area (7.84), liquid and cigarette area (7.72), exercise area (6.88), stress management area (6.84), responsibility of health area (6.35), and nutrition area (6.34). 4. The different lerels of health promoting behavior according to a subject's general factos are following: age (p=0.003), sex (p=0.000), health concern of parents (p= 0.000), taking health programs (p=0.007), case history of familes (p=0.048). Health promoting behavier is also positirely affeted by the following: higher age, social sciences focus, religion, living the relatives', and the higher health concerns of parents. 5. The difference of self-efficiency according to a subject's general factors is positirely affected by sex (p=.008), the health concerns of parents (p=.004), body indexes (p=.001), and the higher health concerns of parents. 6. As the result of analyzing major factors, the most powerful factor appears to be self-efficiency, 26.6% of health promoting behavior. Suggestions: 1. Results of this study point to self-efficiency as a major factor in the health promoting behavior of university students. It is crucial, therefore, to develop a health program to promote self-efficiency and to study how to promote prerention of certain diseases. 2. That health promoting behavior appears low in this study shows that health education should be taken into the university class, with a focus on the daily life of students as its goal.

This descriptive correlational study was conducted to identify the variables related to a health promoting lifestyle in high school students. 304 high school students and 189 vocational high school students living in Taegu city were selected by a convenience sampling method. The data were collected by self-reported questionnaires from August 24 to September 4, 1998. Pender and others' Health Promoting Lifestyle Profile, Shere et al's. Self-Efficacy scale, Wallston et al.'s Internal Health Locus of Control scale, Wares' Health self rating scale and Cohen & Hoberman's Social support scale were used. The data were analyzed by using descriptive statistics, Pearson correlation coefficient, t-test, MANOVA, ANOVA. Tukey verification and Stepwise multiple regression with an SAS program. The results of this study were as follows: 1. The average score of a health promoting lifestyle performance was 2.38(SD=.36) of a 4 point scale .Self-actualization (mean = 2.80. SD = .60). interpersonal support(mean = 2.73, SD=.47), health responsibility (mean=1.53, SD=.47), nutrition(mean=2.64, SD=.63), exercise(mean=2.71. SD=.72) and stress management(mean=2.37, SD=.58) were also analyzed. 2. The combination of self-efficacy, social-support, internal health locus of control. father's educational level and perceived health status explained 37.97% of the variance in health promoting lifestyles. 3. A Health promoting lifestyle showed significant positive correlations with self efficacy(r=.5173. p=.0011), perceived health status(r=.254, p=.001) and internal health locus of control(r=.321. p=.001). 4. According to sex(t=7.38. p=.006). economic state(F=6.62, p=.00l), Father's educational level(F=4.25, p=.005), mother's educational level(F=6.94. p=.000l), the grade of educational performance(F=3.74, p=.024), sleeping hours(F=3.47. p=.032) and social support(F=40.76, p=.0001). there were significant differences and modifying factors in health promoting lifestyles. On the basis of the above findings. self-efficacy in cognitive factors, and social support in modifying factors were identified as the variables which explained most of Pender's health-promotion model. Nursing strategies enhancing self-efficacy and social support which have a more significant effect on health promoting lifestyles should be developed. Further research is required to find out the factors influencing health pormoting lifestyle of high school students.

In the course of screening natural extracts for hair growth, we found that the extract of dried root of Sophora flavescens has the prominent hair growth promoting effect. After topical application of Sophora flavescens extract to the back of C57BL/6 mice, the earlier conversion of telogen-to-anagen phase was induced. In addition, the Sophora flavescens extract revealed to possess potent inhibitory effect on $5{\alpha}$-reductase Ⅰ and Ⅱ activity. The growth of dermal papilla cells and mouse vibrissae hair follicle cultured in vitro, however, was not affected by Sophora flavescens extract treatment. RT-PCR analysis showed that Sophora flavescens extract induced mRNA levels of growth factors such as insulin-like growth factor-Ⅰ and keratinocyte growth factor in dermal papilla cells, suggesting hair growth promoting effect of Sophora flavescens extract is mediated through inhibition of $5{\alpha}$-reductase type Ⅱ activity and the regulation of growth factors in dermal papilla cells. Furthermore, Sophora flavescens extract also showed anti-bacterial effect on Propionibacterium acnes. These results suggest that Sophora flavescens can be used as a potent treatment agent for helping hair growth stimulation and acne inhibition.
