The objectives of this study were to obtain normative data for 45 mother-daughter pairs on spine, femur(neck, ward's triangle, trochanter) and total body BMD (bone mineral density) measured by dual energy X-ray absorptiometry, anthropometric measurement, body composition, biochemical markers, nutrient intakes and energy expenditure, to determin the interrelations of these factors within each group, to measure familial resemblance for each variable. We observed significantly positive correlations between height, weight, head, hip and calf circumferences, tricep, femur and calf skinfold thickness, total lean body mass(=weight-total fat body mass-bone mineral content), protein and fat intakes, Ca index, serum total protein and albumin of monter-daughter pairs(p<.05-p<.001). Among mothers, age, osteocalcin, higher, weight, Ca and energy intakes were predictors of BMDs. Among daughters, weight and energy intake were predictors of BMDs. The BMD in lumbar spine(r=.48, p<.01), femoral neck(r=.38, p<.05), ward's triangle(r=.36, p<.05) of the mothers were significantly correlated with those of the daughters, after adjustment for mother's age, hight, weight, osteocalcin, Ca and energy intakes and daughter's weight, energy intake. In regression analyses, mother's BMD also were positively associated with daughter's BMD in lumbar spine, femoral neck, ward's triangle. Our findings support that mothers with low BMD tended to have daughters with low BMD. In the age groups studied, as well genetic factors as environmental factors may have an important role in determining BMD. This study suggests that women may successfully enhance their genetically determined BMD through adequate nutrient intakes and weight bearing exercise.

Traditional nutrition education has not been shown to consistently produce behavior change. While it has been suggested that using emotion-based messages may be a better way to influence nutrition behavior change, this has not been well tested. Producing emotion-based messages is a multi-step process that begins with exploring subconscious barriers to behavior change rather than the more obvious and typically reported barriers. The purpose of this research was to uncover the emotional reasons, sometimes referred to as emotional pulse points, for mothers' choosing or not choosing to have more family meals. This would then serve as the first step to developing emotion-based messages promoting the benefits of family meals. Five focus group interviews were conducted with 51 low-income Black (n=28) and white (n=23) mothers. Metaphorical techniques were used to determine underlying feelings toward family and family meals. Discussions were video-taped, transcribed, and manually analyzed using a content-driven, immersion/crystallization approach to qualitative data analysis. Four themes emerged around the definition of family: acceptance, sharing, chaos, and protective/loyal. Some mothers felt mealtime was merely obligatory, and described it as stressful. Some reported a preference for attending to their own needs instead of sitting down with their children, while others felt that mealtime should be used to interact with and educate children and felt guilty when they were not able to provide family meals. Three themes emerged around feelings towards having or not having family meals: unimportant, important, and guilty. When explored further, mothers indicated that using the feeling of guilt to encourage family meals might be effective. Data obtained are being used to develop innovative, emotion-based messages that will be tested for effectiveness in promoting family meals.

Background : Irregular meals and insufficient exercise are major modern lifestyle-related risk factors for constipation. This study aimed to examine the effects of the aqueous extract of Dendrobium speciosum var. (DM) on the improvement of intestinal function and prevention of constipation in rats. Methods and Results : Constipation in rat was induced by loperamide (4 mg/kg) injection for 5 days and rats were randomly assigned to the following groups: normal control rats (NOR), constipated rats (LOP induced) and constipated rats supplemented with dulcolax-S (POS), DMSG, 100 mg/kg (DMSG-100), 300 mg/kg (DMSG-300) and 500 mg/kg (DMSG-500). The DMSG groups showed increments in the frequency and amount of stools compared to the LOP group. Loperamide treatment markedly reduced the water content of feces, whereas DMSG administration significantly increased fecal water contents. Moreover, DMSG improved intestinal transit speed in constipated-rats. Alcian blue staining revealed increased mucus production by crypt cells and mucus contents in feces and the mucosal surface. Conclusions : In summary, DM extraction significantly improves intestinal function in rats, which indicates the effectiveness of this extract in the prevention and treatment of constipation.

Purpose: The aim of this study was to identify the barriers to promoting physical activity among obese children from low-income families using community child care (CCC) centers. Methods: This study employed an exploratory-descriptive qualitative research using focus group interviews. The participants were recruited from CCC centers, and 4 focus group interviews were conducted with 10 overweight and obese children and 14 primary caregivers. All interviews were recorded and transcribed verbatim. The data were analyzed using content analysis. Results: The barriers to promoting physical activity were classified into three areas: 1) individual, a lack of will for physical activity; 2) interpersonal, a change in communicative mean with the peer group, absence of parental monitoring due to work-family balance, and an absence of consistent rules; and 3) organizational, lack of physical activity programs and human resources, and confined space for physical activity. Conclusion: The physical activity of children in low-income families is influenced by a range of ecological barriers. These findings can be used to develop tailored intervention to prevent and manage childhood obesity in low-income children.

The study analyzed 343 government-authorized and officially approved textbooks of the Seventh Curriculum's specialized subjects in high school from March to September, 2007. The textbooks were categorized into the area of agriculture, industry, commerce, household and business, science, foreign languages and physical exercise and analyzed in terms of the target and content areas of marine education. And the findings were as follows: First, among the textbooks in the seven groups serving as the focus of this study, 19.8% have oceanic-related information but pages including ocean contents occupy only 0.8%. Consequently ocean-related contents are scarcely included. The ocean-related contents are necessary to be treated goals. Second, the goals of school oceanic education are focused in vocational subjects. In order of commonality, information & knowledge are most frequent, then functionality, followed by activity & participation. There was no education provided focusing on value & attitude. Given that school oceanic educations were selected for promoting the importance of the ocean and highlighting the problems of the ocean, the lack of information & knowledge is of concern. The goals of oceanic education should be augmented to actively and positively participate in the solutions of the problems with knowledge, ocean-friendly value & attitude, and increased activity & participation. Third, the contents of school oceanic education commonly focuses on the relationships of oceans and humans, oceans and ecology, and artificial oceanic environments and facilities. Less common but still introduced are ocean resources, sea pollution, sea preservation and measures. Yet, in contrast there is a lack of education in the ethics of sea preservation.

Objective : The purpose of this study was to determine the differences in the head and tibial acceleration signal magnitudes, and their powers and shock attenuations between flat-footed and normal-footed running. Methods : Ten flat-footed and ten normal-footed subjects ran barefoot on a treadmill with a force plate at 3.22m/s averaged from their preferred running speed using heel-toe running pattern while the head and tibial acceleration in the vertical axis data was collected. The accelerometers were sampled at 2000 Hz and voltage was set at 100 mv, respectively. The peak magnitudes of the head and tibial acceleration signals in time domain were calculated. The power spectral density(PSD) of each signal in the frequency domain was also calculated. In addition to that, shock attenuation was calculated by a transfer function of the head PSD relative to the tibia PSD. A one-way analysis of variance was used to determine the difference in time and frequency domain acceleration variables between the flat-footed and normal-footed groups running. Results : Peaks of the head and tibial acceleration signals were significantly greater during flat-footed group running than normal-footed group running(p<.05). PSDs of the tibial acceleration signal in the lower and higher frequency range were significantly greater during flat-footed running(p<.05), but PSDs of the head acceleration signal were not statistically different between the two groups. Flat-footed group running resulted in significantly greater shock attenuation for the higher frequency ranges compared with normal-footed group running(p<.05). Conclusion : The difference in impact shock magnitude and frequency content between flat-footed and normal-footed group during running suggested that the body had different ability to control impact shock from acceleration. It might be conjectured that flat-footed running was more vulnerable to potential injury than normal-footed running from an impact shock point of view.

This study examined the socioeconomic factors that affect self-rated health (SRH) in healthy adults, and the relationship of SRH to health-related habits, serum biochemical indices, and nutritional intakes. Subjects consisted of 1,154 healthy adults without any known disease, aged 19 to 65 years (average age of 36.7), whose information was obtained from the 2013 Korean National Health and Nutritional Examination Survey data. Of these subjects, 73 rated themselves as 'very healthy,' 460 indicated that they were 'healthy,' 568 self-identified as 'ordinary', and 53 put themselves in the 'unhealthy' category. The proportion of subjects who chose 'unhealthy' was significantly increased with higher frequencies of disruptions in their daily lives (p<0.05), regret after drinking (p<0.05), smoking (p<0.001), and higher levels of stress (p<0.001). On the other hand, the proportion of subjects reported as 'very healthy' was significantly higher with regular intense (p<0.001) or moderate physical activities (p<0.05), regular walking (p<0.05), a perception of being 'normal' in their body image (p<0.01), a decrease of body weight more than 3 kg in the past year (p<0.05), and without risk factors for metabolic syndrome (p<0.05). Serum triglyceride level was lower, and 25-(OH) vitamin D content was significantly higher, in the 'very healthy' group as compared to the 'unhealthy' group (p<0.05). Dietary fiber and vitamin C intakes were significantly higher in the 'very healthy' group than 'unhealthy' group (p<0.05). The overall results suggest that a healthy lifestyle, including regular exercise, non-smoking, good stress management, and higher intakes of fiber and vitamin C, may be potential factors that affect one's positive perception of health.

The purpose of the study was to develop a Web site for the middle-aged women and test the usability of the site. Users' need for information were identified via online survey of 189 middle-aged women. It was found that they had various health problems but very few did any health prevention or health promotion activities. A web site for the middle-aged women was developed based on the result of needs assessment. The site includes content on exercise, diet including weight control, osteoporosis, climacteric, aging, breast and cervical cancer. Besides this health information, FAQ on women's health, my health knowledge test, statistics, link to related institutes and web sites, newspaper articles/mass media clips, journal articles, conferences, papers and other educational information were added. The site was developed as a subsystem of the Healthguide(http://healthguide.kihasa.re.kr). As a way of utilizing the homepage, twenty two women aged 40-50 were recruited at a community-based gathering and health promotion education program was conducted. To test the effectiveness of the education, knowledge, attitude and behavior changes of before and after education were compared. There were significant differences of knowledge and behavior in breast cancer, cervical cancer, osteoporosis, menopause and sexual life. It is expected that Web-based women's health information will contribute to women's health promotion and provide an effective learning media for health education.
