  • BACKGROUND/OBJECTIVES: Metabolic syndrome is closely associated with lifestyle factors, including diet and nutritional intake. Modern trends show a shift in food consumption from healthy home-cooked meals to processed and instant foods. Therefore, this study analyzed the association between ultra-processed food intake and the development of metabolic syndrome in Korean adults based on the data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2013-2018. SUBJECTS/METHODS: The subjects of this study were 17,414 adults aged 19-80 years who participated in the 6th-7th KNHANES. Processed food was classified into four categories, NOVA1 to NOVA4, using 24-h recall data. The higher the NOVA category, the more processed the food. Statistical analysis was conducted using logistic regression to investigate the prevalence of metabolic syndrome according to the consumption of ultra-processed foods. RESULTS: Among the diagnostic criteria for metabolic syndrome, hypertension (odds ratio [OR], 0.72; 95% confidence interval [CI], 0.62-0.85; Q4 vs. Q1, P-trend < 0.001) and high triglycerides (OR, 0.83; 95% CI, 0.72-0.94; Q4 vs. Q1, P-trend < 0.001) showed a correlation with the percentages of energy consumed from ultra-processed foods. The OR for metabolic syndrome, according to the percentages of energy consumed from ultra-processed foods, is shown only for men. The OR showed that the percentages of energy consumed from ultra-processed foods were associated with increased metabolic syndrome. CONCLUSIONS: This study suggests that consumption of ultra-processed foods raises the risk of metabolic syndrome especially among men. To prevent metabolic syndrome, it is necessary to prepare appropriate dietary guidelines for Korean adults.

  • Energy plays a significant role in modern lifestyle because of our extensive reliance over energy-operating devices. Therefore, there is a need for alternative and green energy resources that can fulfill the energy demand. For this, fuel cell (FCs) especially anion exchange membrane fuel cells (AEMFCs) have gained tremendous attention over the other (FCs) due to their fast reaction kinetics without using noble catalyst and allow to use of cheaper polymers with high performance. But lack of highly conductive, chemically, and mechanically stable anion exchange membrane (AEM) still main obstacle to the development of high performance AEMFCs. Therefore, graphene-based polymer composite membranes came into the existence as AEMs for the FCs. The exceptional properties of the graphene help to improve the performance of AEMs. Still, there are lot of challenges in the graphene derivatives based AEMs because of their high tendency of agglomeration in polymer matrix which reduced their potential. To overcome this issue surface modification of graphene derivatives is necessary to restrict their agglomeration and conserved their potential features that can help to improve the performance of AEM. Therefore, this review focus on the surface modification of graphene derivatives and their role in the fabrication of AEMs for the FCs.

  • The plastic furniture made of new materials has enriched and broadened our everyday life not only through development of manufacture but also through consumptions since 1960′s. In relation as well to the need of reducing energy consumption and contributing to environment, the weight of plastic materials has raised concerns in recently. It should be pointed out that development of design technology, which would be risky to develop these synthetic materials was the strategic foundation of Kartell of which principal know-how with plastic techniques. Our rapidly changing lifestyle demands a new design that meet recognition of inflection. In conclusion as we are preparing to enter into the 21st Century, we should go forward with hope and do so with dispatch-dazzling all of us with boldness, thinking imaginatively, transform indifference into action, moving things to the next level in furniture industries, asking the "historic background of designing in plastic seat furniture" questions, challenging the very examples of the past in Kartell, Italy. From this study we have found that it would be useful to understand that the development of technological plastic materials for seat furniture has enabled designers to create ore and more sophisticated design in our millennium life.

  • In the turn of the century, fashion designers have not just drawn upon one or two subcultural styles but have extracted elements from many subcultures to use in a single collection. In true postmodern style these are freely combined with historical, cross-cultural and futuristic influences to create new fashions. The process could be explained by bubble-up phenomenon, retroism. pastiche and pursuit of pleasure. In the course of illustrating subcultural styles transformed into mainstream fashion, the case of Punk was studied as a turning point of modernist and postmodern period which have been introduced by high fashion designers since the birth in 1976. The following cases have continued to appear entering upon the third millennium and the aesthetic value of those can be summarized as ambiguity, eclecticism, and deconstruction. In other words. the energy and authenticity of Punk has been considered to be desirable in high fashion, however designers focus on clothing and adornment rather than ideology and lifestyle. The aesthetic property of subcultural style defeats the established notion of standardized fashion and stimulates new consciousness. which allows a room to be diversified and subdivided.

  • This study was performed to estimate serum 25-hydroxyvitamin D level and to evaluate the relationship between serum 2S-hydroxyvitamin D level and associated factors. The subjects were 61 premenopausal working women aged 30 - 49 y in Busan. The serum 25-hydroxyvitamin D level was measured by radioimmunoassay. Data for physiological characteristics, lifestyle factors, physical activity and nutrient intake were assessed by questionnaire including information about outdoor activity time, daily activity diary and 24 hr recall method. The mean vitamin D intake was 3.12 ug, which corresponded to $62.5\%$ of the Korean RDA. The mean level of serum 25-hydroxyvitamin D was 31.0 ng/mL. Low 25-hydroxyvitamin D (<25 nmol/L) was not found in the subjects. The serum 2S-hydroxyvitamin D level showed positive significant correlations with exercise hours, daily energy expenditure, hours of outdoor activity per weekdays (p < 0.001, P < 0.05, P < 0.05). Exercise hours were found to be the most important determinant of serum 25-hydroxyvitamin D level. Therefore nutritional education for increasing hours of physical activity including indoor and outdoor exercise, is needed for premenopausal working women to increase vitamin D status.

  • This study was performed to investigate the relationships among bone mineral densities (BMD), anthropometric data and lifestyle factors in the elderly. Subjects included 138 elderly (male: 38, female: 100) aged over 65 years, who were home-(dwelling in a low-income area of Puchon City. The BMDs of the lumbar spines (LS), femoral necks (FN), Ward′s triangles (WT) and trochanters (TC) were measured by dual energy X-ray absorptiometry. The females showed significantly lower BMDs in four sites (p < 0.0001) . The elderly aged over 75 revealed significantly more decreased femoral BMDs than the elderly aged 65 to 74. Female with BMIs of 20 to 25, showed significantly higher BMDs in LS, FN and trochanter than those with BMIs of less than 20. However, males displayed significantly higher BMDs in only LS with increasing BMIs. THe BMDs of LS correlated with weights (r = 0.543, p < 0.001), heights (r = 0.477, p < 0.001), upper arm circumferences (r=0.368, p < 0.01), waist circumferences (r=0.367, p < 0.001), subscapular skinfold thicknesses (r=0.363, p < 0.001) and flip circumferences (r=0.231, p < 0.01). Non-smokers and non-drinkers shelved significantly higher BMDs in trochanters only in the case of the males. Female milk-drinkers showed significantly elevated LS BMDs. Eighteen percent of the males were assessed as having osteoporosis, as compared to fifty percent of the females. Ninety-three percent of the females and 81.6% of the males responded that they often or always had "difficulty in standing for a long time".

  • Purpose: To evaluate physical characteristics, lifestyle related to bone-health, and bone mineral density (BMD) in mothers and their daughters and to determine the predictors of BMD. Method: BMDs at the forearm, lumbar spine, and femur were measured in 101 healthy, mother-daughter pairs by dual energy X-ray absorptiometry. Mother-daughter differences between general characteristics, means for BMDs were assessed by ${\chi}^2$-test, t-tests. Multiple regression analyses were used to identify predictors of BMD in each group. Results: Mothers had significantly higher BMD than their daughters at forearm, lumbar spine, and femur. The predictors of mothers' BMDs were body weight, body mass index (BMI) and percentage body fat, explaining 5.1~31.6% of the variation in BMDs. BMI, percentage body fat and their mother's BMD of the corresponding site bone were predictors in daughters, explaining 17.5~31.6% of the variations in BMDs. Conclusion: These results indicate the importance of weight on bone that the BMDs seems to be related to fat free mass both in young-adult daughters and in middle aged mothers. These also suggest the importance ofintervention for the development of BMD in daughter of mother with low BMD.

  • This study intends to propose the fundamentals of 'Ecovillage' design by researching into the cycle system of material of 'Crystalwaters' which is having been in charge of a leading role of GEN since 1996 (GEN was formed in 1996) as Ecovillage in Australia. First, to secure the water resources, we can store up rain and the water of valley, and dam. Second, we are able to use the natural filter apparatus, do tree-planting of roof to gain better quality of water. Third, it is to save the energy as supplying water. For it, we make the best of a gravity that is one of the cycle principle of water. Forth, to build a Dam can make a site of scenic beauty, do the role of recreation place and provide against emergencies (a fire, drought) as well as make a mild climate. Fifth, it can reduce the environment load because of sewage and garbage as making it compost. This is possible by treating biologically using composting apparatus of the dry or wet process. Sixth, it is to reduce the environmental pollution as to discharge seperating a recycable waste, an organic matter being able to make it compost. Finally, first of all, environmentally friendly inhabitant consciousness from lifestyle and production style plays an importent part for water cycle and the ecological cycle of waste and sewage.

  • The purpose of this study was to measure the effects of counseling for hypertension patients. the subjects were 44 hypertension patients who visited the general, hospital, located in Daegu, to receive medical treatments. Among 44 hypertension patient, 22 patients received the nutrition counseling three times for 8 weeks and the rest of the patients didn't as a non-counseling group(control group). The lifestyle, food habit, nutrient intakes, anthropometric measurements, and body fat and blood pressure as a main index were analysed before and after the nutrition counseling. The result after the nutrition counseling are as follows: 1) Body mass index(BMI), systolic blood pressure(SBP) and diastolic blood pressure(DBP) were significantly decreased in women(p<0.05). 2) The food habit score and nutrition knowledge score were dramatically increased(p<0.001). 3) The calcium intake was significantly increased in women(p<0.01). And energy, carbohydrate and fat intakes were decreased both men and women but there were no significant differences. The calcium intake as an Index of nutrition quality(INQ) and nutrient adequacy ratio(NAR) were significantly increased 5) Fat and cholesterol intakes in a group whose blood pressure reduced were significantly decreased compared with a group that had the same or higher blood pressure. These results showed that a well-planned nutrition counseling program would reduce the risk of cardiovascular disease.

  • This study was performed to identify the roles of residents for the environmentally sound and sustainable development, taco-polis(kologisches Bauen), eco-village and Symbiotic Housing. These buildings will achieve energy efficiency through design strategies such as passive solar heating system, natural cooling and day lighting. Their infrastructure will feature parking on the periphery, extensive pedestrian paths, outdoor ground lights that preserve stellar visibility, and environmentally sensitive technologies such as low writer use fixtures. And they will restore biodiversity while protecting the wildlife, wetlands, forests, soil, air and water. Their houses wile be designed to support home-based occupations, offering high-speed Internet access and other options to promote a localized, sustainable economy. To support and encourage the evolution of sustainable settlements, it is necessary to prepare constructing the physical facilities and the social functions relating with residents. The roles of residents are important to provide a high Quality lifestyle and to integrate a supportive social environment with a low-impact way of life. This study concluded the four main roles of residents for the sustainable of Eco-polis and Ecovillage. 1. Residents assist transition towards a sustainable society as eco-conscious consumers in the planning stage. 2. Residents live in a ecological way for the sustainable ecovillage. 3. Residents exchange information and education for increasing the community glue as a communication network. 4. Residents support and transmit their cultural vitality and tradition for the next generation. So, users are expected to encourage resident's participation in the planning, design, ongoing management and maintenance of the sustainable ecovillage.
