The purpose of this survey was to investigate the relationship among obese children, dietary intake and environmental factors. Therefore, this survey compared obese children with normal children on dietary intake and environmental factors. The survey were 110 obese children and 110 normal children whose age, height, and sex were same as the obese children of 21 elementary school in Inchon. The statistical analysis of data was completed using SAS program. The results were summarized as follows : 1) The student's obesity was related to parent's obesity and number of their siblings. There were significant differences between obese groups and normal group for these two factors. 2) Meal time of the obese group showed more irregularity than that of the normal group. Otherwise, the normal group were more "piclity" about special food than the obese group(p<0.05). Also obese children showed unconsious eating while reading or watching TV(p<0.01). The normal group attended physical education class more eagerily the obese group(p<0.001). There was no significant difference between obese children and normal children for learning habits. 3) Obese children shoed higher intake of nutrients compared to normal children. Among all the nutrients, minerals and vitamins showed significant differences. Therefore, further study on obese children and their intake of minerals and vitamin is needed. Also, in order to prevent factors which influence obesity, nutrition education at home as well as school was needed.as needed.

This study is intended to investigate the demographic characteristics and socio-economic status of students, and to reveal the correlations between food habit and health condition by Todai health Index. The results of this study were summerized as followes: 1) the sex ratio of the subjects was 309 males: 129 females. Mean score of the food habit was 7,56 in males and 8.88 in females. The subjects were included in Fair and Poor group generally. Food habit score of students living their own home were significantly higher generally. Food habit score of students living their own home were significantly higher than those of the others (Lodging & Relatives, Self-Boarding, Dormitory, and so forth). 2) In males and females, mean of height and weight were 171.6cm, 62.1kg and 159.9cm, 50.9kg, respectively. Though there was insignificant difference in the physical index according to food habit score in general, there was a special trend in case of male that the higher food habit score they have, the higher physical index they get. The subjects with low food habit score showed the higher THI point in Life-irregularity, Straight-forwardness, depression and Sufferings than those with high food habit score. The female subjects with high food habit score showed the lower THI point in depression, on the contrary, showed higher in vanity. There was significant correlation between instant food, drinking and smoking and THI point.

This study re-examines new aesthetic values pursued by Givenchy, analyzing by the Haute Couture line's chief designers. The following conclusions have been reached: Hubert de Givenchy pursued modernity, infused with simplicity and structured stability. In particular, Audrey Hepburn, who was a loyal client and used his line in several movies, provided him the platform for international exposure which he used to further develop what became known as the "Hepburn" style. The subsequent brief tenure of John Galliano did yield the fantastic and magnificent "Galliano-style", but with irregularity. Based on romanticism, it redefined fashion using a wide range of colors, subjects and decoration. His successor, Alexander McQueen, applied opposite elements using a hybrid technique of pastiche, parody and collage. With innovative inspiration he compromised the concepts of gender, time, space and cultures and recreated futuristic forms of nature, animals, insects and mythical images. Julien Macdonald, who was appointed in 2001 as the Artistic Director for the women's collections, minimized his individual style and preferred feminine, graceful and sexy silhouettes. He breathed fresh life in to Givenchy Haute Couture, reinterpreting the Hepburn style in a modernistic mode. Being passed on the responsibility for both collections (i.e., haute couture and ready-to-wear) in 2005, Riccardo Tisci redefined elegance, combining his unique and tailored gothic style with Givenchy's grace. He is developing the future of Givenchy, experimenting with volume, silhouettes, new kinds of fabric and techniques.

Background: A number of studies have reported complication after reduction of nasal bone fractures. Among complicated cases, some showed improvement in shape of the nose with passage of time. Therefore, we examined these changes using computed tomography (CT) images taken over intervals. Methods: CT scans of 50 patients with new nasal bone fractures were reviewed, and the images were compared amongst preoperative, immediately postoperative, and one month scans. Changes in nasal bone shape, were evaluated based on the angle of nasal bone arch between the nasal bone and frontal process of maxilla, overall shape of arch, mal-alignment of fracture segments involving bony irregularity or bony displacement. These evaluations were used to separate postoperative outcomes into 5 groups: excellent, good, fair, poor, and very poor. Results: Immediate postoperative nasal shape was excellent in 10 cases, good in 31 cases, fair in 8 cases, and poor results in a single case. Postoperative shape at one month was excellent in 37 cases, good in 12 cases, fair in a single case. Conclusion: The overall shape of nasal bone after fracture reduction tended to improve with passage of time.

The etymological meaning of 'the Picturesque' is "after the manner of painters." It had begun to be used from the end of Classical era and become popular in Romantic era. The concept of the Picturesque in the Classical era is an allusion to the Classical paintings, history paintings or ideal landscapes. As the idea of these paintings was the Beautiful Nature, the most crucial of the Classical Picturesque were that a painting should represent some significant human action; that all the parts of this painting should contribute to the whole; that verbal commentaries were needed. The influence of the Picturesque on the garden design can be summarized as the invention of 'the Landscape Garden.' In the Landscape Garden, human action was central and formal and painterly techiniques were used to highlight human action. The subjectivization of concept of of the beauty resulted in the cult of the Picturesque. In the controversy by Price and Knight, the Picturesque and its influence on the garden design was contended variously. Price criticized the monotonous gardens of Brown's and named "roughness, sudden varitation and irregularity" as the three hallmarks of the Picturesque. Knight contended " that the Picturesque consisted only in a manner of viewing things with an eye and mind educated in the principles of painting" and "that gardens should reproduce as fully as possible the qualities that made the pictures of Rosa or Hobbema delightful."

The global force and interaction body force density were evaluated in permanent magnets by using the virtual air-gap scheme incorporating the finite-element method. Until now, the virtual air-gap concept has been successfully applied to calculate a contact force and a body force density in soft magnetic materials. These force calculating methods have been called as generalized methods such as the generalized magnetic charge force density method, the generalized magnetizing current force density method, and the generalized Kelvin force density method. For permanent magnets, however, there have been few research works on a contact force and a force density field. Unlike the conventional force calculating methods resulting in surface force densities, the generalized methods are novel methods of evaluating body force density. These generalized methods yield the actual total force, but their distributions have an irregularity, which seems to be random distributions of body force density. Inside permanent magnets, however, a smooth pattern was obtained in the interaction body force density, which represents the interacting force field among magnetic materials. To evaluate the interaction body force density, the intrinsic force density should be withdrawn from the total force density. Several analysis models with permanent magnets were tested to verify the proposed methods evaluating the interaction body force density and the contact force, in which the permanent magnet contacts with a soft magnetic material.

Short term load forecasts complexly affected by socioeconomic factors and weather variables have non-linear characteristics. Thus far, researchers have improved load forecast technologies through diverse techniques such as artificial neural networks, fuzzy theories, and statistical methods in order to enhance the accuracy of load forecasts. Short term load forecast errors for special days are relatively much higher than that of weekdays. The errors are mainly caused by the irregularity of social activities and insufficient similar past data required for constructing load forecast models. In this study, the load characteristics of Lunar New Year's Day holidays well known for the highest error occurrence holiday period are analyzed to propose a load forecast technique for Lunar New Year's Day holidays. To solve the insufficient input data problem, the similarity of the load patterns of past Lunar New Year's Day holidays having similar patterns was judged by Euclid distance. Lunar New Year's Day holidays periods for 2011-2012 were forecasted by the proposed method which shows that the proposed algorithm yields better results than the comprehensive analysis method or the knowledge-based method.

This study investigates the physical properties of Murata Vortex Spinning (MVS) blended yarn with yarn count(20's, 30's, 40's) and blend ratio(Polyester 100, Polyester70:Cotton30, Polyester50:Cotton50, Polyester30:Cotton70, and Polyester50:Tencel40:Cotton10). This study evaluated tenacity, elongation, bending rigidity, bending hysteresis, hairiness coefficient, irregularity and twist number. The structure of MVS blended yarn influenced stress, strain, bending rigidity, bending hysteresis and the hairiness coefficient of MVS blended yarn decreased as the yarn count increased. MVS blended yarn consists of core and sheath. The core of MVS blended yarn is composed of a parallel fiber with a wrapping fiber that covers thecore fiber. This special structure of the MVS blended yarn effects the physical properties of the yarn; in addition, the mechanical properties of the component fibers influenced the stress, strain, bending rigidity, bending hysteresis and hairiness coefficient of MVS blended yarn with the blend ratio. Polyester decreases and cotton increases resulted in decreased physical properties. A similar polyester content increased the tencel and physical properties. Appropriate physical properties and a variety of touch expression can be realized through a correct blend ratio.

This study was performed to compare dietary behaviors based on residence types of female college students. Self reports on dietary behavior and one-day dietary records were obtained from 227 female college students using anonymous questionnaires. The mean age of the subjects was $20.4{\pm}1.43$, and the height and weight were $162.5{\pm}4.8cm$ and $52.3{\pm}7.9kg$, respectively, The dietary behavior of female college students was inadequate, showing indifference to dietary balance, irregularity of meals, skipping breakfast, and high experience of drinking. One-day dietary records were obtained from 24k recall methods also showed a high number registering skipped meal status ($55.3\%$) and less diverse food intake (DVS, 12.5; DDS, 3.93). The students in self boarding residence were especially more likely not to eat properly and their dietary behaviors were found to be significantly poor. In the case of home residence, food intake frequency scores for milk and dairy products, fruits, and fishes were significantly higher, however the students in self boarding residences showed high food intake frequency scores in salted food, retort food, canned food, and especially instant ramyun. Therefore, more attention needs to be given to them to recognize the problems in their own dietary behaviors and more practical nutritional supports, like developing a menu for breakfast in college cafeterias, would be helpful to improve their dietary choices.

The dynamic characterization is important in making accurate predictions of the seismic response of the hybrid structures dominated by different damping mechanisms. Different damping characteristics arise from the construction of the tower with different materials: steel for the upper part; reinforced concrete for the lower main part and interaction with supporting soil. The process of modeling damping matrices and experimental verification is challenging because damping cannot be determined via static tests as can mass and stiffness. The assumption of classical damping is not appropriate if the system to be analyzed consists of two or more parts with significantly different levels of damping, such as steel/concrete mixed structure - supporting soil coupled system. The dynamic response of structures is critically determined by the damping mechanisms, and its value is very important for the design and analysis of vibrating structures. An analytical approach capable of evaluating the equivalent modal damping ratio from structural components is desirable for improving seismic design. Two approaches are considered to define and investigate dynamic characteristics of hybrid tower of cable-stayed bridges: The first approach makes use of a simplified approximation of two lumped masses to investigate the structure irregularity effects including damping of different material, mass ratio, frequency ratio on dynamic characteristics and modal damping; the second approach employs a detailed numerical step-by step integration procedure in which the damping matrices of the upper and the lower substructures are modeled with the Rayleigh damping formulation.
