The purposes of this study were to investigate blood profiles and nutrient intakes of groups that are different in obese levels, and to find the credible predictor of insulin resistance. The subjects were classified as normal weight (%IBW${\leq}$ 110), obese without MS and obese with MS according to IDF definition of the risk group in metabolic syndrome (MS). Subjects of this study were included 137 (59 boys, 78 girls) free living children and adolescents (mean age $12.6{\pm}3.4$ years) in Gangneung area, South Korea. %IBW of normal weight (94.9%), obese without MS (123.8%) and obese with MS (131.5%) were significantly different among groups. HOMA-IR had positive correlations with TG (r = 0.634), waist circumference (r = 0.553), atherogenic index (r = 0.513), %IBW (r = 0.453) and ALT (r = 0.360), but showed negative correlations with HDL cholesterol (r = -0.417, p < 0.001). HOMA-IR showed positive correlation with polyunsaturated fatty acid intake (p < 0.05). The energy intake of obese with MS was 1762 kcal/day which was not significantly different from those of normal weight and obese without MS. Total fatty acid intakes of two obese groups were significantly higher than that of normal weight. The results of this study suggest that waist circumference and ALT as well as TG, atherogenic index and weight can be credible indices to predict the insulin resistance in children and in adolescents. In addition, nutrition education and adequate diet should be provided to prevent MS in children and in adolescents.

Most of the recently developed robots are human friendly robots which imitate an animal or human such as entertainment robot, bio-mimetic robot and humanoid robot. Interest in these robots are increasing since the social trend is focused on health, welfare, and graying. By these social backgrounds, robots become more human friendly and suitable for home or personal environment. The more bio-mimetic robots resemble living creature, the more human feels familiarity. People feel close friendship not only when they feed a pet, but also when they watch a pet having the food. Most of entertainment robots and pet robots use internal-type batteries and have a self-recharging function. Entertainment robots and pet robots with internal-type batteries are not able to operate during charging the battery. So far there have been a few robots that do not depend on a battery. However, they need a bulky energy conversion unit and a slug or foods as an energy source, which is not suitable for home or personal application. In this paper, we introduce a new bio-mimetic entertainment robot with autonomous feeding functionality, called ELIRO-1(Eating LIzard RObot version 1). The ELIRO-1 is able to find a food (a small battery), feed by itself and evacuate. We describe the design concept of the autonomous feeding mechanism of the ELIRO-1, characteristics of sub-parts of the manufactured mechanism and the control system.

The nutritional status of pre-school children is important for both physical growth and functional development. This study investigated the anthropometric, nutrient intakes and dietary quality of the pre-school children living in Asan for planning nutritional education program. The dietary intakes were measured by 2-day 24 hr recall recorded by children's mothers and the anthropometric data were collected by measuring children's weights, heights, and percent body fat at Asan Public Health Center. The children were 161 boys and 129 girls aged 5 and 6 years. When children's nutritional status was determined by their anthropometric status (underweight, normal weight and overweight) determined by z-score (normal range between -1.00 and 1.00), only 1.4% of the children belonged to underweight group while 55.7% and 42.9% belonged to normal and overweight groups, respectively. Significantly higher number of children belonged to overweight group for 5 year-olds. No differences were observed in nutrient intakes, nutrient adequacy ratio (NAR) and index of nutritional quality (INQ) values among nutritional status groups. Intakes of the most nutrients were adequate, but NAR and INQ of calcium and zinc were low. When nutrient intakes, NAR and INQ were compared by sex or age, all nutrient intakes were appropriate except calcium and zinc intakes of 6 year-olds. Nutrient intakes of 5 years were higher than those of 6 years. The mean of nutrient adequacy ratio (MAR) was 0.85 and mean INQ was 1.51 for all participants. The nutritional management program for pre-school children in Asan would be directed differently by age groups and education material should contain contents educating to consume moderate amount of food for 5 year-olds and to increase intake of foods with mineral nutrients such as calcium and zinc for 6 year-olds.

This study investigated factors affecting the bone mineral density (BMD) of Korean young adult women (20~30 yrs) living in Seoul, according to the state of employment. Data on BMD and anthropometric and biochemical measurements were obtained from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V) (2010~2011). BMD of the working group (WG) was generally higher than that of the non-working group (NWG). The prevalence of osteopenia, and osteoporosis between the groups was 29.0/31.5%, and 12.9/18.5% from 20~29 yrs as well as 25.5/24.1%, and 20.2/20.5% from 30~39 yrs, respectively. From 20~29 yrs, prevalence of osteopenia and osteoporosis in the WG was lower than that of the NWG. Alkaline phosphatase activity of the WG was lower than that of the NWG. In the WG, from 20~29 yrs, total femur BMD showed significant positive correlations with waist circumstance and BMI. In the NWG, from 20~29 yrs, total femur, femoral neck, and lumbar spine BMDs showed significant positive correlations with weight and fat mass, whereas they showed significant negative correlations with vitamin D. In the WG, from 30~39 yrs, total femur and femoral neck BMDs showed significant positive correlations with weight and free fat mass. The results of this study show that BMD of young adult women is insufficient regardless of their employment status. Therefore, practical and systematic programs are required to improve the BMD of young adult women as well as to maintain healthy bone levels.

This study is to develop the double capsulation technology in order to increase the conservativeness and stability of unstable materials such as vitamins, polyphenols, natural active ingredients. And also, best way of triple matrix capsulation using natural polymers were detail described. As the first capsulation with w/o/w (water-in-oil-in-water) emulsifying system, our study group was especially made to soft and moisture cream using 5wt% of sucrose ester emulsifier as first capsulation. Nutrient agents are squalane, camellia oil. Triple matrix capsulation was formed with the best stabilized bead type capsules when it blended of chitosan, algin, sodium-potassium alginate. The bead diameter size was about 2.0~4.5mm (mean diameter: 3.2mm). Activity of lactobacillus containing cream for depending on various pH variations showed that alkalinity ($pH=10.8{\pm}0.5$) condition was higher than acidity ($pH=4.2{\pm}0.2$) and neutrality ($pH=7.1{\pm}0.3$) conditions. After a month, it also was certified to the activity of lactobacillus in incubated at $37{\pm}1^{\circ}C$ in culture medium. As application of food industry, we developed the containing lactobacillus capsule and 7 colored kinds of double and triple matrix capsulation in yogurt cream and active ingredients. As for above mentioned those results, one of tool to stabilize the living lactobacillus, doubled matrix capsulation greatly be expected to contribute to food industry. Furthermore, it can be expected to apply the drug delivery system (DDS) to active ingredients of stabilizing technologies at drug, pharmaceutical division and cosmetic industry, etc.

Biocompatible capsules have recently been highlighted as novel delivery platforms of any "materials" (e.g., drug, food, agriculture pesticide) to address current problems of living systems such as humans, animals, and plats in academia and industry for agriculture, biological, biomedical, environmental, food applications. For example, biocompatible alginate capsules were proposed as a delivery platform of biocontrol agents (e.g., bacterial antagonists) for an alternative to antibiotics, which will be a potential strategy in future agriculture. Here, we proposed a new platform based on biocompatible alginate capsules that can control the movements as an active target delivery strategy for various applications including agriculture and biological engineering. We designed and fabricated large scale biocompatible capsules using alginates and custom-made nozzles as well as gelling solutions. To develop the active target delivery platforms, we incorporated the iron oxide nanoparticles in the large scale alginate capsules. It was found that the sizes of large scale alginate capsules could be controlled via various working conditions such as concentrations of alginate solutions and iron oxide nanoparticles. As a proof of concept work, we showed that the iron oxide particles-incorporated large scale alginate capsules could be moved actively by the magnetic fields, which would be a strategy as active target delivery platforms for agriculture and biological engineering (e.g., controlled delivery of agriculture pesticides and biocontrol agents).

The aim of this study is to learn the effects of ST36 ST44 and ST25 ST36 electroacupuncture stimulation on high fat diet-induced obese mouse. The control group was provided with high fat diet without electroacupuncture stimulation, while the experimental group received a electroacupuncture stimulation on ST36 ST44 and ST25 ST36 with three frequencies (10Hz, 100Hz, 200Hz) for 5 times a week during five week periods with the high fat diet. We investigated the body weight, weight gain, and food intake. After the electroacupuncture stimulation, a significant inhibition of increase in weight was found in the experimental group compared with the high fat diet group. But there were no significant differences made by the change of acupoint combinations and frequencies. After the electroacupuncture stimulation, no significant change was found in the food intakes, but the weight gain a week was decreased compared with the high fat diet group. Electroacupuncture stimulation may be effective in treatments of obesity to high fat diet, But no significant difference was found between three frequencies.

The role of free radicals in the progression of many diseases and aging has been given a great attention and total antioxidant status (TAS) has shown to be reduced with aging. The incidence of hypertension has shown to be relatively high in the aged population, and it is known to be associated with increased obesity and oxidative stress. The aim of this study was to examine the obesity indices and the total antioxidant status in hypertensive elderly (64y$\alpha$-tocopherol, $\beta$-carotene and ascorbic acid did not show their significant correlations with TAS. These results showed that the hypertensive elderly are prone to be obese and to have increased TAS. Due to unknown factors affecting TAS values, measurement of plasma TAS as a sole indicator of total antioxidant capacity is limited to fully understanding changes in the body's free radical trapping power. However, the results from the current study may suggest that hypertension and/or obesity might increase oxidative stress, followed by increased the body's total antioxidant defense system.

This study was conducted to investigate the nutrient intake, dietary and weight control behaviors and iron deficiency of adolescent girls. The subjects were 216 female middle school students living in urban and rural areas of Inchon. Thin cross- sectional study was conducted by questionnaires and data were analyze by SAS program. Nutrient intakes collected from 3 day-recalls were analyzed by the Computer Aided Nutritional Analysis Program(CAN-pro). The mean height, weight. BMI and obesity index for the subjects were 158.2 cm, 51.1kg, 20.4 and -5.3 % in urban students and 155.9 cm, 49.3 kg 21.1 and -8.2% in rural students, respectively. Easting blood samples were obtained and analyzed for iron nutritional status. The mean obesity index of the urban students was higher than that of the rural students. The proportion of the overweight group was higher in urban students compared to rural students, However, over 10% of both area students belonged to the low weight group, respectively. Most students of both areas skipped breakfast and the main reason was on appetite and lack of time. Urban students were more concerned with body image. The nutrients which showed a lower mean intake as percentile of RDA were Ca, iron, vit A an Vit B$_2$ and most nutrient intakes of urban students were significantly higher compared to those of rural students. These results indicate that nutrient intakes in the female middle school students were considerably lower than the RDA. Also they had undesirable food habits and lower self-satisfaction with their body image, There were significant differences in the mean MCV, TIBC and serum ferritin between urban and rural area subjects. Mean Hb, Hct, MCH, MCHC and TS, bowaver, were not significantly different. Prevalence of iron deficiency greatly varied by indices from urban(11.5%) and rural (8.7%) when judged by Hb to urban(23.1) and rural (23.3%) by serum ferrition. Therefore, proper nutrition education is required for good nutrition desirable food habits, weight control, and guidance for iron deficiency in anemic female of adolescents.

This paper begins with the thesis that the so-called 'Be Slow' Movement has not only affected the contemporary life style but also the current fashion trend in the West as well as in Korea. The influence of the 'Be Slow' Movement on the everyday life of Western and Korean society can be documented by recent books, news reports, and many articles from various kinds of mass media and fashion magazines since the year 2000. The results of this study can be summarized as follows. First. the 'Be Slow' Movement is a new cultural phenomenon and very different from that of the past century. It has emerged very recently and it could affect the life style o( its followers for a long period of time. Second, the influence of 'Be Slow' Movement on everyday life can be witnessed in many behavioral choices. such as the preference of organic food and natural cooking for food and the preference of rural life and a green patch of land for housing. Some aspects of the way of rearing the children and long-term planning of one's life are also under the influence of 'Be Slow' Movement. In a way. the life style Proposed by the 'Be Slow' Movement is somewhat similar to that of 'Bobos'. Third, the influence of 'Be Slow' Movement on the current fashion trend can be observed in the appreciation of time-consuming labour and increased usage of D.I.Y. clothing. The higher value of fashion goods with handcrafted part or scarce luxury item are good examples of the influence by the 'Be Slow' Movement. One can say that the 'Be Slow' Movement is not retrogression, but a re-creation of time and space to be grateful for one's life. Thus, it is not anti-technology but a commercialism with technology in order to enhance the quality of life and to place people in the center of production and consumption. Consequently, one may say that the 'Be Slow' Movement is a appropriate and affluent way of living.
