In order to elucidate the mechanism of red-colored phenomena(RCP) in ginseng(Panax ginseng C.A. Meyer), distribution of inorganic elements of ginseng root and its surrounding soil, and microflora in the soil were investigated. Red brown colored-substances were accumulated in the cell wall of epidermis at early stage of red-colored ginseng (RCG). Cell wall of the late stage of RCG was disordered and microorganisms were shown in the disordered cell wall. Al, Si and Fe contents among inorpanic elements in the epidermis of RCG were higher at two or three times than that of healthy ginseng. On the other hand, K content was higher at three times in healthy ginseng than that of RCG. Especially, Fe content was higher at three times in lateral roots of RCG than that of healthy ginseng. Total 21 strains of microorganisms were isolated on the 523 medium from surface soil, surrounding soil of both healthy and RCG, and RCG. Six strains of microorganisms among them were resistant to 2 mM Fe. Two species in Bacillus app. and Lactobacillus app. , and one species in Micrococcus sp. and Npisseria sp. respectively were identified. It seemed that RCP was closely related with the distribution and uptake of inorganic elements, was also correlated Fe-independent metabolism of microorganisms.

Objectives: To investigate the different effects of Sa-Am acupuncture with Spleen Jung-gyuck and Spleen Seung-gyuck on the radial pulse in healthy subjects. Methods: Sixty healthy volunteers (30 males and 30 females) participated in this study. The participants were randomly divided into three groups: control (C), Sa-Am acupuncture with Spleen Jung-gyuck (SP+) and Sa-Am acupuncture with Spleen Seung-gyuck (SP-). The radial pulse was measured using a multi-step tonometry system before, and 0, 30 and 60 minutes after acupuncture. Results: The heart rate adjusted radial augmentation index (RAI/HR) and high-tensioned pulse area (W area) significantly increased in the SP- group compared to the C and SP+ groups in males. The systolic pulse period (T4) increased significantly in the SP- group compared to the C and SP+ groups in females. The RAI/HR had positive correlations with W area and T4. Conclusion: The effects of Sa-Am acupuncture with Spleen Jung-gyuck and Spleen Seung-gyuck are different. Sa-Am acupuncture with Spleen Seung-gyuck induces acute increases of radial pulse parameters related to arterial stiffness in healthy subjects.

Rusty root of ginseng has been known as one of the limiting factors in ginseng production in Korea. An attempt was, therefore, made to elucidate biological and chemical natures of the rusty root, and the redox Potential of the ginseng cultivated soils were measured and compared with diseased and non-diseased soils. Reddish discoloration was most frequently observed on the epidermis of ginseng root and the pigments were accumulated in all epidermal cells of the diseased lesions. The lower the redox potential of the ginseng cultivated soil was, the more severe the rusty root was observed. Fe content in the diseased epidermis was 3 times higher than that of healthy one. Organic acids such as oxalic, malonic, succinic, and citric acids were also higher in the mss root than in the healthy one. Thin layer chromatogram of phenolic acid fractions obtained from the epidermal cells of the rusty root of ginseng exhibited 3 to 4 unidentified substances not found in the healthy root. Also lignification of the epidermal cells and the activity of phenylalanine ammonia lyase were greater in the rusty root than the healthy root. Colony formation and conidia production of F. solani, And mycelial growth and sclerotium formation of Sclerotinia sp. isolated from ginseng root were suppressed in a nutritionally minimal medium supplemented with water extract of rusty ginseng root epidermis. It is, therefore, suggested that rusty root of ginseng is caused by unfavorable rhizosphere environmental stress or stresses resulting abnormal metabolism in the root as a selfdefence mechanism of non-specific resistance responses.

Purpose: The purpose of this study was to examine the effects of health promotion program on healthy aging preparation for late middle aged women. Methods: The research design was a non-equivalent control group quasi-experimental study. Participants were recruited from K and Y cities in Gyeong-nam Province from October, 2013 to January, 2014. They were 26 for the experimental group and 31 for the control group. The experimental group participated in a health promotion program for healthy aging preparation. The program consisted of education, exercise, and small group discussion over 8 weeks. Data were analyzed by Chi-square, t-test and ANCOVA, using the PASW 18.0 program. Results: There were significant improvements in aging anxiety and general self-efficacy, health promoting behaviors in the experimental group compared to those of the control group. However, there was no significant differences in attitude toward older adults between the two groups. Conclusion: The health promotion program on healthy aging preparation for late middle aged women was found to be effective in enhancing aging anxiety and self-efficacy, and health promoting behavior. Thus, the developed program is recommended for use in clinical practice as an effective nursing intervention for late middle aged women in order to keep up with their health in later life.

Purpose: The purpose of this study was to examine changes in functional assessment measures (FAMs) and spatiotemporal gait parameters (STGPs) in healthy older adults before and after a 6-week intervention of a proprioceptive neuromuscular facilitation (PNF) training program. Methods: Thirty healthy older adults (mean age: $73.37{\pm}1.21$ age range: 65-79) were randomly assigned either to an experimental group (participating in a 6-week intervention of PNF training) or a control group (only performing daily activities). Participants in the control group did not receive any training program. Performance was assessed by recording changes in the FAMs and STGPs using functional assessment tools and GAITRite. Results: Participants in the PNF group showed significantly improved functional assessment measures and increased stride length, cadence, velocity, and step width (p<0.05). No significant differences in FAMs and STGPs were found in the control group (p>0.05). Conclusion: Participation in a PNF training program improves FAMs and STGPs, thereby increasing the ability of healthy older adults to maintain dynamic balance during functional performance and gait. These findings support the use of PNF training programs as effective fall-prevention programs for the elderly.

Objective : The objective of this study was to investigate the effects of breath meditation with neurofeedback on memory, concentration of healthy adult volunteers Method 25 healthy adult volunteers were divided into two groups. One group was treated with breath meditation and real neurofeedback, but the other group was administered with breath meditation and sham neurofeedback three times a week for 10 sessions, Before and after 10 sessions neurofeedback, all subjects were measured by cognitive functions assessment, heart rate variability, BDI, STAI, K-WAIS, HRSD, VAS about amnesia. Results : 1. Breath Meditation decreased error rate and increased concentration, cognition strength, and success rate of Cognitive Functions Assessment. Also, Breath Medication elevated IQ score of K-WAIS short form. 2. Sham : neurofeedback increased concentration, cognition strength compared to Real neurofeedback. Conclusion : The results suggest that breath meditation might effect cognitive function of healthy adult positively, but neurofeedback is not clear. In order to prove whether neurofeedback is effective or not, it should be studied more.

The primary purpose of this study was to compare the hamstring-to-quadriceps strength(H/Q) ratios in collegiate soccer players and normal age-matched healthy students, and the secondary purpose was to investigate the changes in the H/Q ratio according to the degree of knee flexion. Twenty-five subjects volunteered to participate in this study. The study group comprised 12 healthy male collegiate soccer players, and the control group, 13 healthy age-matched male collegiate students. The modified N-K table was used for isometric strength measurement(unit: N). Mann-Whitney tests were performed to determine the differences in the H/Q ratios of soccer players and age-matched students at different knee flexion angles of the dominant leg. The strength of the hamstring muscle in the study group was significantly lower than that observed in the control group at knee flexion angles of $60^{\circ}$ (p<.001), $90^{\circ}$ (p<.01), and $120^{\circ}$ (p<05). The strength of the quadriceps muscle in the study group was significantly higher than that observed in the control group at flexion angles of $30^{\circ}$ (p<.001) and $60^{\circ}$ (p<.05). The H/Q ratios in the study and control groups differed significantly at all angles ($60^{\circ}$, p<.001, $90^{\circ}$, p<.001 and $120^{\circ}$, p<.001).

Around and in the area of Wolgot-Muon, Gimpo-Gun, Kyunggi province, I examined total bacteria, general Pseudomonas spp., fluorescent Pseudomonas spp., in soil layers and also in different kinds of soil of respective diseased, uncultivated, and healthy areas, and found the followings. 1. In the diseased and uncultivated areas, the content of moisture and silt was greater than in the healthy area. 2. Contrary to the above, the healthy area contained a greater amount of inorganic elements such as $P_2O_5$, K, Ca and of soil particle such as Cs and Fs. The degree of pH and content of Mg were even in three types of soils. 3. Total bacteria were found in abundance in the healthy soil. It was observed that in all types of areas, bacteria reside in abundance in the rhizosphere, i.e., 10-15 cm layers and that the closer the surface, the greater the numbers of the bacteria. 4. General Pseudomonas spp. were also found to the greater in number on the surface of the soil, especially so in the rhizosphere, with the numbers decreasing as the soil layers increase. Numbers of this bacteria in all types of area were nearly uniform. 5. A great number of fluorescent Pseudomonas spp. were found in the diseased area, especially so in the rhizosphere.

Purpose: The purpose of this study was to analyse the level of sexual function among breast cancer survivors as compared with that among healthy women. Method: A total of 208 women participated in this study: 103 breast cancer survivors attending self-help group and 105 community-residing healthy women in G city. A self-reported questionnaire with the Female Sexual Function Index (FSFI) was used to obtain data. Data were analyzed using the SPSS Win 14.0 $K^+$ for descriptive statistics, t-test, and two-way ANOVA. Results: The sexual function score of breast cancer survivors was significantly lower than that of healthy women, respectively $14.9{\pm}9.9$ and $20.6{\pm}11.1$ (p<0.001). The sexual function of recurrent breast cancer survivors was significantly lower than that of women without recurrence. However, there were no significant differences in the sexual function score according to the cancer stage, period since diagnosis, and types of cancer treatment modality. Conclusion: The findings indicate the importance of sex-related counseling and educational programs to improve the quality of life of breast cancer survivors.

In order to elucidate the prevalence of anti-HEV, anti-HCV and HBsAg in ALT (Alanine Aminotransferase)-elevated patient group and healthy person control group, we examined anti-HEV, anti-HCV and HBsAg in 92 persons, respectively. The prevalence of anti-HEV in ALT-elevated patient group (4.3%) was not significantly higher than that (2.2%) of healthy person control group(P>0.05). While in healthy person control group the prevalence of anti-HEV in female (2.4%) was higher than that (2.0%) in male, and in ALT-elevated group male (4.8%) was higher than female (3.3%), there were no significances. The positive rate of anti-HEV was not significantly increased with age between healthy person control and ALT-elevated patient group. The odds ratio's of HEV, HCV and HBV with ALT-elevated patient group were 2.05 (95% CI: 0.31-16.54), 8.67 (95% CI: 1.06-188.63) and 7.23 (95% CI: 2.47-22.71), respectively, but had no significance. It was turned out that HCV and HBV were significantly correlated with ALT-elevated patient group, but HEV had no significance with it in this paper.
