  • Communication device to use slight movement for serious disabled is proposed. This device is developed mainly for patients suffering from ALS or a cerebral infarction. They often have communication difficulty because of deterioration of muscular functions. Features of this device are that the device is wearable on the user’s body and that it detects the movement of eyebrow. Because of these features, it is quite easy to install the sensor on the patient’s body, not like the conventional sensors. Furthermore, an adaptive communication software is incorporated. A feature of this software is that the arrangement and size of the button and window on the display can be optimized depending on the user's physical ability. In the field test it is confirmed that the communication device developed in this study is successfully helped the people with disability for increasing their communication ability.

  • The influence of torsional rigidity of hinged flexible appendage on the linear dynamics of flexible spacecrafts with liquid on board was analyzed by considering the spacecraft's main body as a rigid tank, its flexible appendages as two elastically supported elastic beams, and the onboard liquid as an ideal liquid. The meniscus of the liquid free surface due to surface tension was considered. Using the Lagrangian of the spacecraft's main body (rigid tank), onboard liquid, and two beams (flexible appendages) in addition to assuming the system moved symmetrically, the coupled system frequency equations were obtained by applying the Rayleigh-Ritz method. The influence of the torsional rigidity of the flexible appendages on the spacecraft's coupled vibration characteristics was primary focus of investigation. It was found that coupled vibration modes especially that of appendage considerably changed with torsion spring parameter ${\kappa}_t$ of the flexible appendage. In addition, variation of the main body displacement with system parameters was investigated.

  • In harvesting rice and barley using combine, the inclination of the body caused by the irregular surface condition of the field and the soil sinking from the unbalanced weight during the grain collection used to make harvesting operation difficult and even impossible. To overcome such a problem hydraulic system far automatic and manual leveling control of a combine has been developed. The system was composed of the combine body and the hydraulic level control system mounted on it. The maximum height of ground clearance was set up to be 290mm. And the limit angle of the leveling control was set up to be $\pm7^{\circ}$. The proposed controller and hydraulic system was implemented to the prototype combine. The prototype combine was designed and built as a separable structure with the body and the track of it. This paper shows results of a specification and design testing with the hydraulic level control system far body of combine.

  • The purpose of this study is to propose apparel sizing system for each body shape of early adolescent boys. The subjects of this study were 549 boys in the capital area. Their body shapes were classified based on 47 anthropometric measurements, 43 photographic measurements and 10 indexed measurements. The apparel sizing system was proposed for each body shape. For data analysis were performed descriptive statistics, correlation analysis and crosstabulation using SPSS Ver. 12. The control dimensions to propose apparel sizing system were stature and waist circumference for the lower garments. Intervals between sizes were 5cm for stature and irregular for waist circumference. For each type, $5{\sim}8$ sizes were proposed for lower garments. Reference measurements suggested fur lower garments were 7 items. This study is meaningful in that it proposed apparel sizing system for each type of body shape. The results of this study are expected to contribute to planning sizes according to the type of body shape and improving the fitness of ready-made clothes in apparel and school uniform manufacturers.

  • This research is to understand customer satisfaction with virtual fitting based on a 3D body scanner and avatars as well as differences between avatars and the 'real me'. To this end, this research examined Korean college students to facilitate 3D body scanning, avatar generation and surveys. The author used 3D body scan data with direct measurements to identify differences between the 3D body scan data-based 'my avatar' and 'real me' in the virtual dress fitting system. The survey results on 'the level of customer awareness on 3D body scanner' found that the majority of both genders did not know about it and indicated a lower usability to incorporate IT technology into the fashion industry. The question in the 3D body scanning and avatar found an affirmative attitude. Satisfaction levels on the 3D avatars' similarity with 'own body' and garment fitting were positive and indicated a need for further technological improvements to express the avatars identical to customers' own body. More research is necessary for the accuracy of sizes for 3D body scanning that measure body sizes while wearing clothes. Avatars based on such datamay be less similar to 'own body' and cause customer dissatisfaction. Thus, further technology development is required to narrow gaps using data to make avatars that provide more accurate virtual fitting simulation services to customers.

  • In this study, computer applied engineering (CAE) techniques are fully used to conduct structural and dynamic analyses of a whole huge wind turbine system including composite blades, tower and nacelle. For this study, computational fluid dynamics (CFD) is used to predict aerodynamic loads of the rotating wind-turbine blade model. Multi-body dynamic structural analyses are conducted based on the non-linear finite element method (FEM) by using super-element method for composite laminates blade. Three-dimensional finite element model of a wind turbine system is constructed including power train(main shaft, gear box, coupling, generator), bedplate and tower. The results for multi-body dynamic simulations on the wind turbine's critical operating conditions are presented in detail.

  • The purpose of this study is to classify body type by BMI and to inquire about body satisfaction and fitness apparel depending on body type among women 20-50years of age. As a result, body types are classified into three groups: lean, normal, and obese figures. On front silhouette, the normal type occupies most in women belonged to lean figure group, the obese lower part of the bodytype in normal figure group, and the obese upper part of the body type in obese figure group. On the other, in side silhouette, the slender type is prevalent in lean figure group, hip obesity in normal figure group, and trunk obesity in obese figure group. In particular, women in the obese figure group were distributed among the various body types. The obese figure group had a lower fitness apparel in the measurement of circumference(e.g., chest, waist, and hip) related to obesity in comparison with measurement of length. Therefore, the development of an optimal sizing system in response to the various body types in the obese figure group is needed to provide more diversity in aesthetic design and continuity among various sizing systems.
