This study puts the purpose in providing the scientific basis of dance motion as an artistic expression by analyzing the kinematic variable and the distribution factor of power affecting the motion, which is connected to the turn, right after the arabesque motion according to the existence and non existence of using the arm in the arabesque motion of modern dance. As a result of this study, arabesque turn motion, not using the upper limbs, used more turning force of head and body than the arabesque turn motion, using the upper limbs, and arabesque turn using the upper limbs obtained the turning force, using the right shoulder. The range of the hip joint on the left and the position change of left tiptoe in the Arabesque turn motion using the upper limbs is largely ascended to the vertical axis, while, the position of tiptoe in the Arabesque turn motion, not using the upper limbs is dropped to the lower part of each event. In the replacement of body center, Arabesque turn motion using the upper limbs is moved more to the turning axis than arabesque turn motion not using the upper limbs. As a result of maximum vertical ground reaction force, Arabesque turn motion using the upper limbs appeared to be a lower value than the Arabesque turn motion not using the upper limbs.

Rehabilitation of upper limb motor function of hemiplegic patient must maintain interest and demand a device for a quantitative evaluation of rehabilitation training. In this paper, we developed the device that is composed of arm cradle, handle, and balance ball for rehabilitation exercise. We have performed experiment for validity as to whether to use the rehabilitation device when tilting the upper extremity training device developed to measure changes in the EMG signal to the main upper limb muscles for 7 healthy volunteers. We have analyzed muscle activation signals on agonist and antagonist as a reference in the muscle contraction and relaxation in the upper limb extension and flexion when the balance-handle device is tilted to front-rear and left-right. The experimental results showed that a tendency of muscle activation of biceps, triceps, and deltoid used in upper limb motor function of hemiplegic patients from extension and flexion evaluation items of Fugl-Meyer Assessment(FMA). These results may be helpful for rehabilitation training for upper limb motor function of hemiplegic patients by utilizing a developed unit.

The purpose of this study was to find out the effect that muscle activity of upper extremity and functional test in the case of the stroke patient by using the feedback mirror therapy. Sixteen subjects were recruited and randomly divided into two groups. one group was trained feedback mirror therapy and other group was action observation training. This process was carried out five times a week for eight weeks. To upper extremity test was used to MFT, FMA and in order to test UT, DM, BB, FCR, ECRL used to muscle activity. After the training, exclude FCR an upper extremity motor function of target showed significant difference between two groups and especially an experimental group showed significant muscle activity and MFT, FMA score improvement of UT, DM, BB, ECRL. Therefore, feedback mirror therapy is more upper extremity motor function and muscle activity improvement effect than action observation training.

Manual wheelchair propulsion can lead to pain and injuries of users due to mechanical inefficiency of wheelchair propulsion motion. The kinetic analysis of the upper limbs during manual wheelchair propulsion needs to be studied. A two dimensional inverse dynamic model of upper limbs was developed to compute the joint torque during manual wheelchair propulsion. The model was composed of three segments corresponding to upper arm, lower arm and hand. These segments connected in series by revolute joints constitute open chain mechanism in sagittal plane. The inverse dynamic method is based on Newton-Euler formalism. The model was applied to data collected in experiments. Kinematic data of upper limbs during wheelchair propulsion were obtained from three dimensional trajectories of markers collected by a motion capture system. Kinetic data as external forces applied on the hand were obtained from a dynamometer. The joint rotation angles and joint torques were computed using the inverse dynamic model. The developed model is for upper limbs biomechanics and can easily be extended to three dimensional dynamic model.

Objectives : Sojadodamgangki-tang and its main components are traditional korean medicinal methods for treatment of cough, sputum and dyspnea. Using a respiratory inflammatory model, we intend to reveal the anti-inflammatory effect and its immune mechanism of Sojadodamgangki-tang. Methods : We used a papain-induced respiratory inflammatory mouse model. 8-week-old female BALB/C mice were divided into 3 groups as follows: the following groups: saline control group, papain treated group (vehicle), papain and Sojadodamgangki-tang(200 mg/kg) treated group (n=4). To evaluate the anti-inflammatory effect of Sojadodamgangki-tang extracts, inflammatory cell infiltration was measured in bronchoalveolar lavage fluid (BALF) and nasal lavage fluid (NALF). In addition, the effects of Sojadodamgangki-tang extracts on Th2 cell population in lung were determined by using flow cytometry. Results : Sojadodamgangki-tang extracts administration reduced inflammatory cell infiltration in BALF and NALF, especially of eosinophils. Furthermore, total immunogloblin (Ig)-E levels was reduced in BALF and serum by drug administration. Interestingly, Sojadodamgangki-tang extracts treatment also decreased the Th2 cell (CD4⁺GATA3⁺) population in lung. Conclusions : Our findings indicate Sojadodamgangki-tang extracts have anti-inflammatory effects by mediating Th2 cell and B cell activation.

(주)상지피앤아이를 방문해 사장을 만나기 위해서는 어디로 가야 할까. 이렇게 쉬운 질문을 하는 이유는 간단하다. 왜냐하면 사장실이 없기 때문에 어디로 가야할지 모르거나 혹은 눈에 띄는 대로 만날 수 있기 때문이다. 상지피앤아이의 이창래 사장은 고객이 부르면 가고, 직원들이 결재할 일이 있으면 직원 자리로 가면 되기 때문에 사장실이 필요 없다는 생각이다. 조금은 의아한 생각이 들지만 이 사장은 가만히 머물러있기를 거부한다. 그래서 마라톤도 하고, 끊임없이 생각도 하고, 고객을 찾기도 하고, 직원들을 만나기도 한다.

This study is about the paper of Mulberry(桑紙). The paper which was usually applied to the ancient bookpaper and documents. But there is a rare record about it today. So the paper was made from the Mulberry(뽕나무) bast fiber using traditional handcraft method. and Paper Mulberry(닥나무) by traditional method. And tested by physical and optical methods in comparisons with Paper Mulberry(닥나무). The ratio of length/width of Mulberry fiber was 475, and its lignin content was lower than the Paper Mulberry. The Mulberry paper had similar forming properties and physical strength to the Paper Mulberry fiber. Therefore, the Mulberry fiber seem to be a good paper fiber for traditional paper. For the aging test, in the thermal acceleration treatment for 72 hours and 144 hours at the temperature of $105^{\circ}C$ incubator, the Mulberry paper was more deteriorative than the Paper Mulberry. In the ultraviolet acceleration treatment for 100 hours and 200 hours the Mulberry paper was less interior to the Paper Mullberry, in the increase of treatment time. And the Mulberry paper was approved to be a good traditional paper in appearance. Furthumore, in considing the sample of bred Mulberry species grown today, its paper is thought to be superio to the paper of Paper Mulberry in symptom of senility in natural ultraviolet light.

본 연구는 양손이 불편하거나 없는 상지장애인이 도어락의 잠금 해제를 할 수 있도록 화자 인식 기술을 이용한 도어락을 구현하였다. 현재까지 대부분의 도어락 기술은 일반인 대상으로 개발되어 생체인식 기술을 활용하는 단계까지 발전하였으나 기본적으로는 사람이 가장 잘 사용하는 신체 부위인 손을 기준으로 발달되어 손의 활용이 필요한 방식으로 양손이 불편한 상지 장애인의 사용에는 불편함을 주었다. 따라서 본 연구는 도어락 장금 장치에 화자인식 기술을 활용하여 상지 장애인도 이용 가능한 도어락 잠금 패키지를 제안하고, 구현한다. 일반인에서 상지 장애인도 사용할 수 있도록 화자 인식 기술을 이용하여 보다 보편적으로 사용 가능한 도어락 시스템을 설계하는데 기여할 수 있다.

In this paper, we proposed a design of upper-limb rehabilitation device with power-assist function for stroke survivals. The designed upper-limb rehabilitation device has three degrees of freedom； it is possible to perform flexion and extension motions of wrist, index finger and the other fingers except the thumb independently. The power-assist for wrist motion is performed by a pneumatic double-acting cylinder, but the fingers are actuated by electrical linear actuators to assist motions. A prototype upper-limb rehabilitation device and its controller were implemented. The position controller showed 0.8 mm errors in the steady-state. Experimental results showed that the proposed upper-limb rehabilitation device with power-assist function is feasible.
