Today's young generation in digital era has a rich education environment and convenient life, on the other hand, there was negative impact on growth as normal body type because of adverse impact on an excessive study and insufficient exercise, etc. Also, for these people in IT culture generation, using small mobile including computer for long time is becoming main issue as changing factor in posture and body type in terms of spine like their neck disc. This body-typed characteristic reaches to normal adult body type in the process of physical development of adult woman and has least modification in body type. Therefore, despite of early young generation, body suitability of upper body clothes might caused imbalance. So, for intended to early 20s women, to design clothes with consideration on imbalance of body type by bended and curved spine, body type studies about size of upper body and forms are needed. As this researcher measured the body type of early 20s college women in metropolitan area, changes in body type of young generation with use of digital equipment recently were recognized since straight body type was decreased unequally and had characteristic in terms of changes to be bended body type. The changes of these body type should be considered to make clothes. Also, since there are some restrictions on this research objects in terms of local and numbers of measured objects, a broad interpretation of result on this research should be really careful.

The study was designed to observe the effect of complete listing for 10 days on body fatness, serum leptin level and lipid profile in thirty women who were admitted to fasting Clinical Program in Kyung-Hee Oriental Medical Center. Most of the subjects had food habits of over-eating and preferred oily foods which was correlated to the increase of body weight and BMI during realimentation. Average loss of body weight was 7.98kg and waist-hip ratio was significantly decreased during fasting. Body weight showed significant positive correlation with body fat(r=0.8182), lean body mass(r=0.7797) and total body water(r=0.7563). Body fat was gradually reduced after 9 days fasting, but lean body mass was not diminished any more after 7 days luring. Serum leptin level was significantly decreased after luring and re-feeding. The leptin showed significant positive correlation with body weight(r=0.9324), body mass index(r=0.8279) and body fat(r=0.8376). The levels of serum total cholesterol and LDL-C were significantly increased but HDL-C level was significantly decreased after fasting which increased could be harmful for persons with hypercholesterolemia. VLDL-C and triglyceride levels were not significantly decreased after fasting. Serum total free fatty acid level was significantly increased after fasting. These data suggest that the best way of maintaining the reduced body weight was to carry out the modification of food habits and behavior in daily lift. It could not be recommended to repeat often complete luting for reduction of body weight. (Korean J Nutrition 33(1) : 42-48, 2000)

Body fat distribution in patients with Prader-Willi syndrome (PWS) is characterized by reduce lean body mass (LBM), increased total body fat mass (FM), and lower percentage of visceral adipose tissue (VAT). Individuals with PWS seem to have a lower risk for insulin resistance with high levels of adiponectin, an anti-atherogenic adipocytokine that is decreased in visceral fat hypertrophy subjects compared to simple obese subjects, both in children and in adults. The mechanism of the reduction in visceral adiposity in PWS is still unclear. It might be related to qualitative intrinsic characteristics of adipocyte or novel genetic influences on the control of fat distribution. However, obesity remains a critical problem, and obesity status plays a crucial role in individual metabolic risk clustering and development of metabolic syndrome (Mets) in PWS children and adults. Long-term growth hormone (GH) treatment after cessation of skeletal growth improved body composition, with an increase in lean body mass and a reduction in total body fat and subcutaneous and visceral fat in PWS adults. Thus, the role of GH is important after childhood because it might attenuate obesity and Mets in PWS adult by adipocyte modification.

Body-on-frame type vehicle has a set of frame bushes between body and frame for vibration isolation. Such frame bushes are important vibration transmission paths to passenger space for excitations during driving. In order to reduce the vibration level of passenger space, therefore, change of complex stiffness of the frame bushes is more efficient than modification of other parts of the vehicle such as body, frame and suspension. The purpose of this study is to reduce the vibration level for ride comfort by optimization of complex stiffness of frame bushes. In order to do this, a simple finite element vehicle model was constructed and complex stiffness of the frame bushes was set to be design variables. The objective function was defined to reflect frequency dependence of passenger ride comfort. Genetic algorithm and sub-structure synthesis were applied for minimization of the objective function. After optimization level at a position of interest on the car body was reduced by about 43.7 % in RMS value. Causes for optimization results are discussed.

Structural modifications of a ship may cause a fatal accident such as sinking and wrecking of ship. Especially, barge ship can be easily reconstructed to load more bulk cargo. In this study, for a real accident case, change of mooring force due to structural modification was analyzed to evaluate accident risk. A two dimensional dynamic model for the barge ship was constructed to compute mooring forces with related to floating motion. The equation of motion was established in Matlab code and buoyancy was calculated by using direct integration of submerged volume. The results showed that wind force, current force, and mooring force after rebuilding was approximately 4.3 kN, 14 kN, 1,561 kN respectively. The maximum force of mooring force according to the length of mooring cable were 1,614 kN at 30 m of mooring cable. Thus, an arbitrary modification of ship lead instability and unreliable result so that illegal rebuilding of ship should be avoided.

An experimental modal analysis and dynamic stiffness evaluation of a moving body structure of a high speed machining center are presented in this paper. The natural frequencies and corresponding modes, and dynamic compliance of a moving body structure of high speed machining center are investigated by using F.E.M., hydraulic exciter test, and impulse hammer test. The lowest three natural frequencies were found to be 56.6 Hz, 112.7 Hz, and 142.7 Hz by FEA respectively, while those were 55 Hz, 112 Hz, 131 Hz by experimental analysis. Furthermore, both computed and measured absolute dynamic compliances of the moving body structure in iso-direction showed good agreement especially at the first two mode frequencies. With our experimental data, the dynamic characteristics of the machining center can be exploited to get a new development of structural dynamic design and modification.

The finite element alternating method is a convenient and efficient method to analyze three-dimensional cracks embedded in an infinite or a finite body because the method has the property that the uncracked body and cracks can be modeled independently. In this paper the method was applied for fatigue crack growth simulation. A surface crack in a cylinder was considered as an initial crack and the crack configurations and stress intensity factors during the crack growth were obtained. In this paper the finite element alternating method proposed by Nikishkov, Park and Atluri was used after modification. In the method, as the required solution for a crack in an infinite body, the symmetric Galerkin boundary element method formulated by Li and Mear was used. And a crack was modeled as distribution of displacement discontinuities, and the governing equation was formulated as singularity-reduced integral equations.

A concept of crash energy absorbing (CEA) lattice structure for an inflatable morphing vehicle body (Lee et al. 2008) has been investigated as a method of providing rigidity and energy absorption capability during a vehicular collision (Lee et al. 2007). A modified analytical model for the CEA lattice structure design is described in this paper. The modification of the analytic model was made with a stiffness approach for the elastic region and updated plastic limit analysis with a pure plastic bending deformation concept and amended elongation factors for the plastic region. The proposed CEA structure is composed of a morphing lattice structure with movable thin-walled members for morphing purposes, members that will be locked in designated positions either before or during the crash. What will be described here is how to model the CEA structure analytically based on the energy absorbed by the CEA structure.

The use of relaxing cosmetic products is more and more widespread on the self care market, since stress is considered as a major cause of discomfort in modem life. Cortisol, the stress hormone, helps the human body to regulate itself by acting on carbonhydrate, proteins and fat metabolisms. IgA are immune molecules involved in the stress response of the human body. The less the human body is stressed, the more the salivary IgA rate increases. Salivary cortisol and IgA have the advantage of being easily assessed with non invasive methods. Finally, conductance is the measurement of the modification in the electrical resistance of the skin. By this means, the measurement of the conductance enable the assessment of somebody's stress.(omitted)
