In this paper, we propose the haptic system for the real-time virtual environment-control, which controls the sense of sight, hearing and touch. In order to maintain the stable haptic system in this study, we apply the proxy force rendering algorithm and the real-time graphic deformation algorithm based on the FEM. The applied proxy algorithm makes the system possible to be more stable and prompt with a virtual object. Moreover, the haptic rendering algorithm is applied to work out a problem that the tactual transaction-period is different from the graphic transaction- period. The graphic deformation algorithm is developed in the real-time using the deformed FEM. To apply the FEM, a deformed material-model is produced and then the graphic deformation with this model is able to force. Consequently, the graphic rendering algorithm is deduced by the real-time calculation and simplification because the purpose of this system is to transact in the real time. Applying this system to the PC, we prove that it is possible to deform the graphics and transact the haptic. Finally we suggest the variable simulation program to show the efficiency of this system.

Recently in the mobile market, the communication technology which bases on the sense of sight, sound, and touch has been developed. However, human beings uses all five - vision, auditory, palatory, olfactory, and tactile - senses to communicate. Therefore, the current paper presents a technology which enables individuals to be aware of other people's emotions through a machinery device. This is achieved by the machine perceiving the tone of the voice, body temperature, pulse, and other biometric signals to recognize the emotion the dispatching individual is experiencing. Once the emotion is recognized, a scent is emitted to the receiving individual. A system which coordinates the emission of scent according to emotional changes is proposed.

In early Highlighting the client's personality especially, home design demands very careful consideration. It's not an easy task to understand the characteristics of each family member, to take into account their requirements, and strike proper harmony among them. For this Sampung Apartment Project, I decided to create a cozy homelike atmosphere by using overall modern and antique furniture, props, and lighting. I tried a different sense of space by choosing wood as the main material, installing furniture that looked antique, and applying painting with touch instead of pictures or wallpaper By the use of the light bulb color overall, lighting was yellow and added more comfort. Local lighting was used in certain places to add more fun along with the props. After choosing white as the main color, point colors were determined according to the client's inclination toward green and blue. The color choice also matched the client's paintings that were in soft green and blue. Each room was planned and color coordinated according to their own characteristics. The children's rooms were planned with such point colors as pink, green, and blue. The master bedroom and the family room were produced around gold and grey color, respectively.

Interaction is an important component in the sense of immersion in augmented reality. However, the function of interaction in augmented reality contents is very weak. Bringing a lot of real environmental information is one of the ways to develop augmented reality, and interaction will naturally develop. In this paper, Leap Motion was used for natural interaction in augmented reality environment through the hand widely used as an interface tool, and extended more from the limited interaction of conventional display touch methods to create a natural interaction. This development of interaction will contribute to the development of various contents as well as augmented reality later.

The purpose of this study is to assess abdominal sensation after free TRAM flap for breast reconstruction. 74 patients underwent breast reconstruction with free TRAM flap by authors and were followed up to check the sensation on abdomen following the surgery at the out patient clinic. They are compared with 20 female volunteer controls. Abdomens were divided into 13 zones, and assessed for superficial touch, superficial pain, temperature, two-point discrimination, and vibration. For all five sensory modalities, subjects were found to have decreased sensation in the umbilical and infraumbilical regions. This was statistically significant compared with controls. Division following pedicle dissection showed more reduction of sensation than non-dissection side. Both Inguinal areas below the donor site closure also showed markedly decreased sensation. Sensation on most area of abdomen recovered in postoperative 1 year, however, there were remained hypoesthesia in umbilical and infraumbilical area after post operative 1 year. This study clearly demonstrates that there is a significant and persistent reduction in abdominal sensibility following free TRAM flap surgery.

This paper proposes the electric stimulus tactile apparatus system(TESTAS) loaded on the haptic interface using ultrasonic motors (USMs) To touch the virtual object like wall in graphic, the 6 DOF haptic interface provides force feedback to users as if it is real. But the case of sharp virtual object like a puncture, it could not provided the sense of pain, but only the reaction-force. After the TESTAS had been loaded on this haptic interface, it could provide not only the force but also the pain to users. In this way, when users take the haptic and tactile informations at the same time, they easily have a correct understanding of virtual object.

The purpose of this study was to compare the characteristics of underwear consumer's underwear purchasing behavior through survey. 630 questionnaires were distributed in Seoul and Chonju and 618 with usable data were analyzed frequency and factor analyses, t-test etc. using SPSSWIN 10.0. program. The results were summarized as follows : Most male consumers buy underwears at discount stores whereas most female consumers at chain store. Throughout all four seasons, more male and female consumers do not wear heat-retaining underwears. Most male and female consumers do not have function-fiber underwears nor functional-finishing and natural-dyeing-treated underwears. Most consumers are not satisfied with these underwears. The most important criteria for most male consumers to choose underwears are comfort levels while in action, the sense of touch, comfort levels while wearing them while not in action, pleasance levels; whereas for females are comfort levels while in action, and comfort levels while wearing them while not in action. Male consumers prefer a little bigger-than-their-bodies size, dry and soft fabrics, plain white color; whereas female consumers prefer a little tight size, dry and soft fabrics and plain beige color, Most consumers want to buy functional-fiber underwears made of yellow- soil-and-charcoal-dyeing fabrics which has jade.

In order to extend the activity range of visually impaired persons, we design and implement a navigation system that supports road information services and points of interest. The proposed navigation system consists of route creation modules and storage modules for visually impaired persons. In particular, the main interface of the navigation system are implemented using TTS(Text-to-Speech) program for sound and braille module that outputs braille with sense of touch. We also use google map APIs that can provide latest map information for the navigation system.

The purpose of this study is to introduce a sensory restoration in reconstructed breast with free TRAM flap to evaluate recovery aspect and recovery quantity. 144 patients underwent breast reconstruction with free TRAM flap by authors and were followed up at the out patient clinique. We discovered that sensory of operated breast was recoverd. We divide the breast into 5 region (upper medial, lower medial, upper lateral, lower lateral, nipple areolar complex) for examining the sensory restoration. Sense of upper medial region & upper lateral region is recovered more quickly than other region. Touch sensation was recovered more quickly than pain sensation, temperature sensation, vibratory sensation. After about 1 year all protective sensation was recovered in all patient. We discovered that severe postop scar and irradiation of breast is related to delayed sensory recovery, age and size of flap is not related to sensory recovery.
