Objectives: It has been demonstrated that acupuncture treats diseases while that the widespread use of that clinically and experimentally. It also has shown that electro-acupuncture(EA) is more effective than manual-acupuncture (MA). The purpose of this study was to investigate effect of EA and MA at combined acupoints on sex and age in rats. Methods: This study measured the effects of acupuncture treatment on small intestinal motility in rats. MA and EA(intensity, 5 times muscle twitch threshold) was applied for 30 minutes to the combined left and right sides acupoints on ST36, ST37, ST39 under enflurane anesthesia. EA and MA applied to the ST36, ST37, ST39 acupoints produced an elevation of small intestinal motility. Results: In experimental groups of combined left and right sides acupoints, only specified groups show elevation of small intestinal motility in male rats, 5 weeks age. Furthermore, combined left and right sides acupoints in EA and MA show differences effects according to the sex, male and female, and the age as 5, 6, 7, 8 weeks. Conclusion : Although these different according to the sex and age in rats do not have a established tendency, the present study suggest that effect of EA and MA are experimentally dependent upon the sex and age on small intestinal motility in rats.

The purpose of this study was to investigate the consumption of health functional foods according to age group. We surveyed 300 subjects with quota sampling aged 10 to 50 and over. The rate of consumption of health functional foods by users was substantial (52.7%). Consumers of health functional foods showed higher scores for interest in health (3.97 vs 3.49, P<0.001) and knowledge of health functional foods (3.79 vs 3.30, P<0.001) than non-consumers of health functional foods. Regarding consumers of health functional foods, the number (P<0.01) and types (P<0.05) of health functional foods, reasons for taking (P<0.05), motivations for buying (P<0.05), periods of taking (P<0.001), cost per month (P<0.01), observance of instruction (P<0.01), and effectiveness (P<0.01) were significantly different according to age group. For non-consumers of health functional foods, reasons for not-taking (P<0.01) and types of health functional foods to be planned (P<0.001) were different according to age group. For consumers and non-consumers, problems (P<0.01) andimprovements (P<0.001) for health functional foods showed significant differences according to age group. The majority of subjects (85.4%) answered that heath functional foods had no side-effects. Reported side effects were inappetence (6.6%), constipation (2.6%), and headache (2.0%). In conclusion, differentiated strategies and specialized education programs according to age group might be needed for promoting adequate consumption and preventing side-effects of health functional foods.

The purpose of this study were 1) to identify the effects of age and sex of Korean adolescents on the psychological variables(body attitudes, public/private self-consciousness, self-esteem), weight control practices, and clothing behaviors, and 2) to identify the relation- ships between psychological variables and weight control practices, and the effects of the variables on clothing behaviors in the adolescent' groups classified by sex and age. The results of this study were as follows: 1) Two factors of body attitudes were identified: Body-shape consciousness and Physical attractiveness. Four factors of clothing attitudes were identified: Clothing interest/dressing for others, Clothing exhibition, Dressing for self, and Psychological clothing-dependerlce. 2) There were significant effects of sex on all of the research variables. Age was found to have effects on Physical attractiveness, self-esteem, public/private self-consciousness, Clothing exhibition, and Psychological clothing- dependence. 3) In the relationships between psychological variables and weight control practices, Body-shape consciousness was negatively correlated with Physical attractiveness in all groups. Also, Body-shape consciousness had effects on weight control practice in all subject groups. 4) Public self-consciousness had direct/indirect effects on the Clothing interest/dressing for others in all subject groups. Private self-consciousness had direct/ indirect effects on dressing for self in high school boys and girls. Body-shape consciousness had indirect effects on Preference for up-to date style in male college students group, whereas weight control practices had effects on the Preference for up-to date style in female college students group. Self-esteem was found to have the effects on clothing behavior in college students groups. Among clothing attitude factors, Clothing exhibition had distinct effects on the Preference for up-to date style in all subject groups, and Clothing interest/dressing for others had effects on Clothing exhibition and Psychological clothing-dependence in high school boys and girs.

To elucidate the effects of a hydroelectric dam construction on annual ring growth of Pinus densiflora, the annual ring widths of 68 trees collected from 7 sites were closely examined. The result was analyzed to ask three special questions first, whether there are real effects of dam construction on the radial growth second, would the magnitude of the effect be different due to two periods of under-construction and post-construction the last, would it be different among age classes. Annual ring growth has been significantly enhanced by the dam construction. Specially, its effect was marked after the construction was finished and the reservoir was filled up with water. There was, however, no remarkable evidence that pine growth would be reduced while the dam was under construction, even though there was a minor decreasing trend. The magnitude of the effect was different among age groups. That is, the changed condition after the construction enhanced relatively the growth of aged trees monre. According to other meterological research since the dam was constructed, the reasons of enhancing pine growth assumed to be the increase of daily temperature, the decreased of daily temperature difference and the increased of rainy days.

This study was to know the effects of massage on the back region in order to reduce stress in middle age women. To investigate the effects of massage to the stress levels of middle aged women, we evaluated blood pressure (BP), heart rate variability (HRV), and ultrasonography before and after back massage. The blood pressure after massage was reduced when compared to that of pre-massage. The HRV spectrum analysis was used Frequency domain analysis such as Mean HRV, normalized low frequency (norm LF), norm high frequency (norm HF), and LF/HF ratio. Post-massage BP tended to be low, but not statistical significant. After Massage, the Mean HRV, norm LF, and LF/HF ratio were significantly reduced, while norm HF was significantly increased as compared with pre-massage. The muscle layer and fat layer were significantly diminished by massage. The study was suggested that massage may be an effective treatment for relief of stress.

The sense of vision is the primary means by which we gather information from our surroundings, and vision loss, therefore, severely compromises the life of the affected individuals, their families, and society. Loss of vision becomes more frequent with age, and diabetic retinopathy, age-related macular degeneration, cataracts, and glaucoma are the major causes of vision impairment. To find active pharmacological compounds that might prevent or ameliorate the vision-threatening eye diseases, numerous studies have been performed, and some botanical compounds, including those extracted from ginseng, have been shown to possess beneficial effects in the treatment or prevention of common ocular diseases. In this review, we summarize the recent reports investigating the therapeutic effects of ginseng and ginsenosides on diverse ocular diseases and discuss their therapeutic potential.

Background: Liver cancer is one of the most common causes of death in the world. In Korea, hepatitis B virus (HBV) is a major risk factor for liver cancer but infection rates have been declining since the implementation of the national vaccination program. In this study, we examined the secular trends in liver cancer mortality to distinguish the effects of age, time period, and birth cohort. Materials and Methods: Data for the annual number of liver cancer deaths in Korean adults (30 years and older) were obtained from the Korean Statistical Information Service for the period from 1984-2013. Joinpoint regression analysis was used to study the shapes of and to detect the changes in mortality trends. Also, an age-period-cohort model was designed to study the effect of each age, period, and birth cohort on liver cancer mortality. Results: For both men and women, the age-standardized mortality rate for liver cancer increased from 1984 to 1993 and decreased thereafter. The highest liver cancer mortality rate has shifted to an older age group in recent years. Within the same birth cohort group, the mortality rate of older age groups has been higher than in the younger age groups. Age-period-cohort analysis showed an association with a high mortality rate in the older age group and in recent years, whereas a decreasing mortality rate were observed in the younger birth cohort. Conclusions: This study confirmed a decreasing trend in liver cancer mortality among Korean men and women after 1993. The trends in mortality rate may be mainly attributed to cohort effects.
