Purpose : This study aims to investigate the effect of somatosensory stimulation on the upper limb sensory and function and self-esteem of stroke patients. Methods : This study period was march 4 to april 4 (5 weeks). The subject were 20 stroke patients with somatosensory impairment in B hospital, seongnam, gyeonggi province. They were devided into two group-experimental and control-with 10 members each. The members of the experimental group underwent somatosensory stimulation, whereas the members of the control group underwent an occupation-based intervention for 5 weeks. Thirty-minute therapy was provided 3 times per week for 5 weeks. Before and after the intervention, both groups were evaluated via light touch, static two-point discrimination, stereognosis, Fugl-Meyer assessment (FMA), and self-esteem scale Results : In this study, light touch was not significant in both groups. Static two-point discrimination was significant among the experimental group member's index fingers. Among the control group members, it was significant in the ring finger. The comparison between the two groups was significant in the index finger. The stereognosis results were significant in the experimental group but not in the control group. The comparison between the groups after the intervention was not significant. FMA was significant in the shoulder/ elbow/ forearm (SEF), hand and coordination among the experimental group. Among the control group, it was significant in the SEF and hand. The comparison between the groups was significant in the SEF, hand and coordination. The self-esteem scale results were significant among both groups, and the comparison between the group's score was likewise significant. Conclusion : In conclusion, somatosensory stimulation therapy increases the static two-point discrimination, stereognosis, upper extremity function, and self-esteem of patients with stroke. Therefore, while somatosensory stimulation therapy is not the best therapy, it is one of the best occupational therapies for stroke patients.

An interface in smart device environment is changing to TUI(touch user interface) environment where a system is being controlled by physical touch, differently from a system controlled through conventional mouse and keyboard. What is more important than anything else in this TUI environment is to implement interface in consideration of learn ability and cognitive constructivism according to user's experience. Therefore, now is the time when it is necessary to carry out various studies on smart content design process going a step farther together with discussing the details of user's experience factor. Hence, this study was intended to look into what effect a user's experiential traits had on the production of contents for the purpose of measures for improving TUI user satisfaction in order to effectively realize contents in smart environment. Results were yielded by using a statistical empirical analysis such as cross-tabulation analysis according to important variable and user, paired t-test, multiple response analysis, and preference frequency analysis of user preference on the basis of a survey. As a result, a system was presented for implementing DFSS(Design For Six Sigma) process. TUI experience factor can be divided into direct habitual experience, direct learning experience, indirect habitual experience, and indirect learning experience. And in the results of study, it was possible to find that the important variables of this study had a positive effect on the improvement of use satisfaction with contents on the whole according to the user convenience of smart contents. This study is expected to have a positive effect on efficient smart device-based contents production by providing objective information according to empirical analysis to smart media-based developer and designer and presenting a model for improving the changed TUI usability.

Almost of alternate computer access devices which assist people with disabilities to utilize the computer connected to computer by some cables or installed in as a S/W program. These devices have some spatial limitations to the people with disabilities, it can't guarantee the free and diverse access to the computer. For these reasons, in this paper, an Android-based mouse program for alternative computer access was developed. A people with physical disabilities who has some limitation of hand movements can use it in anywhere and anytime using only the fine motor skill of the upper limbs. The developed device recognizes the user's point touch and transforms it into the location of mouse cursor. The location information transferred to the computer via Bluetooth communication module equipped in smart devices. Also the group scanning method which can reduce the user's fatigue degree was employed and click, double click, drag & drop functions by hand's movements were equipped. The developed device will help the people with disabilities to use computer with brief touch and convenient operation without spatial limitation.

In this study, the authors aimed to give careful consideration to the circulation of bioenergy (Qi) by using cardiorespiratory massage technique. Finding enlightenment in harmony with nature thousands of years ago, our ancestors created Qi using natural breathing and tried to achieve good health and long life by controling the up and down movement. Experiencing the importance of the abdomen during the hungry times, also, grandmothers cured diseases by rubbing the abdomen, which is the ocean of life with their soft, soothing touch of hand. Naval breathing therapy was formed, based on natural breathing, emotional recognition of grandmothers' soft, soothing touch, and the Theory of Unified Reason and Energy that is the key of Oriental medicine. Natural breathing and Yakson massage are kinds of naturopathy to change body and mind, cure diseases naturally, and maintain the improvement in physical functions by taking care of the abdomen through the creation of Qi and the up and down movement and keeping dynamic balance between the natural world and the inside and outside of human body. It is anticipated that this study could contribute to the practical spread for an active application of naval breathing therapy and be broadly used in scientific clinical researches.

With the increase in the use of mobile banking service, mobile banking has become an attractive target to attackers. Even though many security measures are applied to the current mobile banking service, some threats such as physical theft or penetration to a mobile device from remote side are still remained as unsolved. With aiming to fill this void, we propose a novel approach to prevent e-financial incidents by analyzing mobile device user's input patterns. This approach helps us to distinguish between original user's usage and attacker's usage through analyzing personal input patterns such as input time-interval, finger pressure level on the touch screen. Our proposed method shows high accuracy, and is effective to prevent the e-finance incidents proactively.

A tangible sports game is an exercise game that uses sensors or cameras to track the user's body movements and to feel a sense of reality. Recently, VR indoor sports room systems installed to utilize tangible sports game for physical activity in schools. However, these systems primarily use screen-touch user interaction. In this research, we developed a V-Catch Vision system that uses AI image recognition technology to enable tracking of user movements in three-dimensional space rather than two-dimensional wall touch interaction. We also conducted a usability evaluation experiment to investigate the exercise effects of this system. We tried to evaluate quantitative exercise effects by measuring blood oxygen saturation level, the real-time ECG heart rate variability, and user body movement and angle change of Kinect skeleton. The experiment result showed that there was a statistically significant increase in heart rate and an increase in the amount of body movement when using the V-Catch Vision system. In the subjective evaluation, most subjects found the exercise using this system fun and satisfactory.

The origin of Uchida is strictly avant-garde and carries a social dimension. The work is a challenge to consumption-oriented mass production, a revolt against intrusive one-way communication, and an aversion to oppressive politics. Such a spirit led to a rare communication design that was created in collabolation with the user and designer, both relating to each other's senses of touch and in the same familiar plane. He first began by focusing on the physical movements of objects in order to achieve maximum comfort and lightness. From the beginning, He avoided strong, sturdy solids, and favored the faint, transitory and vulnerable. He choose the pursue "furniture with delicate lines", "to create darkness by layering shadows", all of which are extremely unique and resulted in designs that have a profound presence. Uchida gives various meanings and functions to the grid. This activities and philosophy of Uchida Shigeru influenced on the interior design.the interior design.
