  • This study was to investigate the children's understanding level of nutritional knowledge and the degree of knowledge application into the actual living not only in the with-lunch school but also in the without lunch school. Having expected their obtaining of nutritional knowledge and practical applicating, we compared the with-lunch school children's understanding level of nutritional knowledge, dietary attitude, and completeness of diet life with those of without-lunch school children. In addition to this, we surveyed healthiness, Physical condition, and BMI (Body Mass Index) and compared these factors. The results are as follows. 1. Almost all of the children were standard in physical condition, however they recognized themselves fatty than normal. Mealtime consumption(p<0.05), BMI(p<0.05), and diet attitude points(p<0.001) showed significant difference in the children who regarded the themselves healthy. 2. High correlation was observed between parent's physical shape and mealtime consumption (p<0.05), quantity of eating food (p<0.001), children's BMI(p<0.001) and diet attitude(p<0.05) respectively. 3. The points of itemised nutritional knowledge test was different in accordance with the children's year grade (p<0.05), children's understanding level of health and physical condition(p<0.05), parent's physical shape (p<0.05), and mother's education level(p<0.05) respectively. The points of nutritional knowledge test in both schools showed no difference except the item of vitamin.

  • The purpose of this study was, accordingly, to examine male college student's general body consciousness and their actual condition of wearing clothing, as it's assumed that clothing, which everyone must always wear, might be effective in making up for the physical defect. The findings of this study were as follows : 1. Male College Students'Body Consciousness : They expressed some dissatisfaction with their own body, and they were most discontented with their height, among their bodies. They thought of the western-style shape as an ideal one, as what's considered by them to be ideal was thinner a little than them, being taller with wider shoulder, longer legs, smaller and white face. 2. Male College Students'Characteristics of Clothing Purchasing Behavior : In purchasing clothing, male college students were slightly sensitive about the physical part with which they wasn't satisfied. The clothing pattern preferred by them was an abstract one, and their favorite color was white or black. The greatest number of them put most emphasis on design in buying clothing, and they purchased clothing mainly at special fashion shop. On the whole, they showed an affirmative response toward wearing Korean costume, and they also had a positive opinion about the purchase of reformed Korean dress for everyday life. 3. Male College Students'Characteristics of Wearing Clothing : They appeared not to consider making up for physical weakness. Male college students favored aloha shirt and trousers when they went out. Male college students purchase clothing in consideration of individual, manly, classical, tender, or comfortable factors. 4. Relationship of Body Consciousness to Wearing Behavior : The degree to which they considered covering up physical weakness in wearing clothing was examined, by dividing them into two groups : one was a group that thought their own shape normal, and the other was a group that didn't think of their own shape as normal. As a result, both groups appeared not to consider covering up physical weakness.

  • BACKGROUND/OBJECTIVES: Studies have indicated that university students majoring in nutrition and dietetics or sport sciences may have more obsessions associated with eating attitudes and body shape perception compared to other disciplines i.e. social sciences. Therefore, this study aimed to assess and compare the risk of eating disorders and body shape perception. MATERIALS/METHODS: Data was collected from 773 undergraduate students at the Departments of Nutrition and Dietetics (NDD) (n = 254), Physical Education and Sports (PESD) (n = 263), and Social Sciences (SOC) (n = 256).A socio-demographic and personal information questionnaire, Eating Attitudes Test (EAT-40), Body Shape Questionnaire (BSQ-34), Perceived Figure Rating Scale (FRS) were applied; and body weights and heights were measured. RESULTS: Mean EAT-40 scores showed that, both male and female students of PESD had the highest scores ($7.4{\pm}11.6$) compared with NDD ($14.3{\pm}8.3$) and SOC ($13.0{\pm}6.2$) (P < 0.05). According to EAT-40 classification, high risk in abnormal eating behavior was more in PESD (10.7%) compared to NDD (2.9%) and SOC (0.4%) students (P < 0.05). Students of PESD, who skipped meal, had higher tendency to the risk of eating disorders (P < 0.05). In parallel, body shape perception was found to be marked with higher scores in NDD ($72.0{\pm}28.7$) and PESD ($71.5{\pm}32.8$) compared with SOC ($64.2{\pm}27.5$) students (P < 0.05). Considering BSQ-34 classification, high concern (moderate and marked) for body shape were more in PESD (7.4 %) compared to NDD (5.2%) and SOC (1.9%) students (P < 0.05). The body size judgement via obtained by the FRS scale were generally correlated with BMI. The Body Mass Index levels were in normal range (Mean BMI: $21.9{\pm}2.8kg/m^2$) and generally consistent with FRS data. CONCLUSIONS: Tendency to the abnormal eating behavior and substantial body shape perception were higher in PESD students who have more concern on body shape and were not well-educated about nutrition. In conclusion, substantial concern on physical appearance might affect eating behavior disorders in PESD students.

  • Shape memory materials are widely used in high-tech industries. Although shape memory polymers have been developed, they have a disadvantage, only unidirectional resilience. Shape memory polymers with bi-directional recovery resilience have been actively studied. In this study, a bidirectional shape memory polyurethane was synthesized using poly(${\varepsilon}$-caprolactone) diol, methylene dicyclohexyl diisocyanate, and hydroxyethyl acrylate. The first physical curing occurred between hard segments and hydrogen bondings when the solution was dried. The second curing in acrylate groups was performed by UV exposure. A degree of curing was analyzed by infrared spectroscopy. The shape memory properties of 2 step-cured polyurethanes were investigated as a function of UV curing time.

  • Accurate prediction of size, shape and velocity of a bubble rising through a liquid pool is very important for predicting the particulate removal efficiency in pool scrubbing, for designing engineering safety features to prepare for severe accidents in nuclear power plants, and for predicting the emission of fission products from MCCI (molten core-concrete interaction) process during severe accidents. In this review article, previous studies on the determination of the size, shape and rising velocity of a bubble in liquid are reviewed. Various theoretical and parameterization formulas calculating the bubble size, shape and velocity from physical properties of liquid and gas flowrate are compared. Recent studies tend to suggest simple parameterizations that can easily determine the bubble shape and rising velocity without iteration, whereas iteration has to be performed to determine the bubble shape and velocity in old theories. The recent parameterizations show good agreement with measured data obtained from experiments conducted using different liquid materials with very diverse physical properties, proving themselves to be very useful tools for researchers in related fields.

  • This study was to investigate the appearance orientation and body shape management of adolescents in Daejeon. A survey was performed from December 16th~28th 2015 and 355 respondents were collected for analysis. 45.9% of the subjects were middle school students, whereas 54.1% of them were high school ones. The female and high school students tended to show higher ratings in lookism tendency and interests in beauty care, whereas male and middle school students tended to show higher ratings in physical satisfaction than the others. More than 40% of the respondents perceived them fatter than the standard weight, in particular, girls and the ones with opposite-sex friend perceived them fatter than their actual conditions. On body shape satisfaction, female and high school students indicated lower satisfaction. For body shape management, 75% of the female and 40% of the male students had tried weight control. The frequency and the duration time of exercise had higher for boys than girls, and the ones with opposite-sex friend than without. For methods of weight control, girls were more likely to do diet control, whereas boys were more committed to exercise. In general, students with high appearance orientation tended to control taking snacks and fast food or did diet control for body shape management. Conclusively, continued interest and guidance, not only at home but also in school, is required for students so that they can do proper body shape management to fulfill their appearance orientation and they will improve academic performance by gaining confidence through their appearance satisfaction.

  • In modal analysis, the mode shape reflects the vibration characteristics of the structure, and thus it is widely performed for finite element model updating and structural health monitoring. Generally, the acceleration-based mode shape is suitable to express the characteristics of structures for the translational vibration; however, it is difficult to represent the rotational mode at boundary conditions. A tilt sensor and gyroscope capable of measuring rotational mode are used to analyze the overall behavior of the structure, but extracting its mode shape is the major challenge under the small vibration always. Herein, we conducted a feasibility study on a multi-mode shape estimating approach utilizing a single physical quantity signal. The basic concept of the proposed method is to receive multi-metric dynamic responses from two sensors and obtain mode shapes through bridge loading test with relatively large deformation. In addition, the linear transformation matrix for estimating two mode shapes is derived, and the mode shape based on the gyro sensor data is obtained by acceleration response using ambient vibration. Because the structure's behavior with respect to translational and rotational mode can be confirmed, the proposed method can obtain the total response of the structure considering boundary conditions. To verify the feasibility of the proposed method, we pre-measured dynamic data acquired from five accelerometers and five gyro sensors in a lab-scale test considering bridge structures, and obtained a linear transformation matrix for estimating the multi-mode shapes. In addition, the mode shapes for two physical quantities could be extracted by using only the acceleration data. Finally, the mode shapes estimated by the proposed method were compared with the mode shapes obtained from the two sensors. This study confirmed the applicability of the multi-mode shape estimation approach for accurate damage assessment using multi-dimensional mode shapes of bridge structures, and can be used to evaluate the behavior of structures under ambient vibration.

  • Retail space itself could be one of the marketing strategies, through creating space, and communicating brand identity. Especially for innovative products, such as mobile technology products, store is not just to sell products but to provide experiences so that users can fudge usefulness of products and reduce uncertainties to adopt the products. The purpose of this study is to investigate how environmental features and physical artifacts contribute to promote experiences of innovative products in stores and how physical environment help to establish brand identity. For this study, site visits, observation, and literature review were conducted. For case studies, three retail spaces (Apple, Iriver, Sony) and one service space(TTL) were selected. Compared to the service space, three retail spaces have more transparent and open store front design characteristics. For the experiences of shoppers, products displayed in a radial shape, round shape, column shape, and around peripherals of the stores. A service oriented space, TTL zone is differentiated from three retail spaces in terms of layout, store front design, and experience areas. Compared to the traditional stores selling innovative products, the case stores showed more warm atmosphere using various shape, wood materials, lighting fixtures and furniture.

  • The geometric configuration in the weight-reduced structure is very required to be started from the conceptual design with low cost, high performance and quality. In this point, a structural-topological shape concerned with conceptual design of structure is important. The method used in this paper combines three optimization techniques, where the shape and physical dimensions of the structure and material distribution are hierachically optimized, with the maximum rigidity of structure and lightweight.
