Objectives : We got a good effect in two patients not by subcutaneous but by subcutaneous but by intra-articular bee venom injection treatments at traumatic arthritis of elbow joint, so report it. Methods : We used only intra-articular bee venom injection treatments at acute traumatic arthritis of elbow joint. After measured the VAS(visual analogue) and ROM(range of motion) of elbow joint, we bee venom injection effect. Results and Conclusions : The symptoms(swelling, pain) and the functions of elbow joint were quickly improved through intra-articular bee venom injection treatments. One case was improved that Rt. elbow joint flexion was increased from $60^{\circ}$ to $150^{\circ}$, extension was increased from $20^{\circ}$ to $0^{\circ}$. The other case was improved that Lt. elbow joint flexion was increased from $90^{\circ}$ to $150^{\circ}$, extension was increased from $30^{\circ}$ to $0^{\circ}$, and both were decreased in VAS. The results suggest that bee venom intra-articular injection has acute pain reduction, anti-inflammation effect.

Heat and cold often produce a similar clinical effect but different physiologic mechanisms. The purpose of this study was to compare the effects of local heat and cold therapy on joint pain, discomfort and, ROM of the arthritic knee joint. Thirty female subjects took Ice bag and hot bag with random assignment of initial therapy Subjects rated the degree of Joint pain and discomfort before and after each therapy, and then ROM was measured. The results of the study were as follows : 1. The hot bag group showed significantly lower joint pain & discomfort score than the ice bag group. ROM was increased in the hot bag group compared with subjects in the ice bag group. But there is not significant differences. 2. The ice bag group showed significantly lower joint pain score after than before therapy. But there are no significant differences in discomfort score & ROM between after & before therapy. 3. The hot bag group showed significantly lower joint pain, discomfort score after than before therapy. ROM was significantly increased after than before therapy in hot bag group. Therefore hot bag was significantly more effective than the ice bag in relieving the arthritic joint symptoms. A further study is necessary to determine the effect of local heat and cold therapy including the related variables such as preference for heat or cold.

The purpose of this study is to empirically analyze the effect of cultural distance between partner firms on international joint venture performance, focusing on the moderating effects of the conflict resolution techniques and the competitive relationship between partner firms. We tested hypotheses based on joint venture firms that were surveyed which formed by equity investment between Korean and foreign firms in the manufacturing industry. The empirical analysis results of this study are as follows. First, in international joint ventures, the cultural distance between partner firms was found to have a negative effect on the international joint venture performance, and the higher the cultural distance, the lower the joint venture performance. Second, it was found that constructive conflict resolution techniques weaken the negative impact of the cultural distance between partner firms in international joint ventures on the performance of international joint ventures. Third, competitive relationship between international joint venture partners showed no moderating effect on the relationship between cultural distance and international joint venture performance.

Purpose : This study was conducted to investigate the effect of muscle taping and joint taping on static and dynamic balance in normal adults with chronic ankle instability. Methods : The subjects of this study were 32 people who met the inclusion criteria. This cross-sectional study was conducted using the Kinesio tape, an elastic tape, was used. Subjects were randomized to exclude the effect of sequence, and no taping, joint taping, and muscle taping were applied as taping interventions. One-leg standing test and a Functional reach test were conducted to measure static balance, and Y-balance test was conducted to measure dynamic balance. One way repeated ANOVA was performed to investigate the difference in balance ability according to the taping intervention. If there was a significant difference, a post-hoc was performed using the Bonferroni method. Results : In the case of static balance, joint taping showed more significant results than did no taping and muscle taping (p<.05), and muscle taping showed more significant results than did no taping (p<.05). In the case of dynamic balance, muscle taping showed significantly larger results than did no taping and joint taping (p<.05) and joint taping showed significantly larger results than did no taping (p<.05). Conclusion : This study found that mechanical stimulation of muscles and joint compression by elastic taping increased ankle stability and improved static and dynamic balance. In particular, for static balance, joint taping was more effective than muscle taping, and for dynamic balance, muscle taping was more effective than joint taping. Applying the appropriate taping method to individual subjects has the advantage of maximizing the therapeutic effect for the recovery of balance ability. Similarly, the application of various tapings to subjects with ankle instability will have a positive effect on functional improvement.

Majority of industrial robots are controlled by a simple joint servo control of joint actuators. In this type of control, the performance of control is influenced greatly by the joint interaction torques including Coriolis and centrifugal forces, which act as disturbance torques to the control system. As the speed of the robot increases, the effect of this disturbance torque increases, and makes the high speed-high precision control more difficult to achieve. In this paper, the joint disturbance torque of robots is analyzed. The joint disturbance torque is defined using the coefficients of dynamic equation of motion, and for the case of a 2DOF planar robot, the conditions for the maximum joint disturbance torques are identified, and the effect of link parameters and joint variables on the joint disturbance torque are examined. Then, a solutioin to the optimal path placement problem is proposed that minimizes the joint disturbance torque are examined. then, a solution to the optimal path placement problem is proposed that minimizes the joint disturbance torque during a straight line motion. the proposed method is illustrated using computer simulation. the proposed solution method cna be applied to the class of robots that are controlled by independent joint sevo control, which includes the vast majority of industrial robots. By minimizing the joint disturbacne torque during the motion, the simple joint servo controlled robot can move with improved path tracking accuracy at high speed.

Various models have been proposed by several researchers for predicting the exterior RC beam-column joint shear strength. Most of these models were calibrated and verified with some limited experimental database. From the models it has been identified that the joint shear strength majorly depends on ten governing parameters. In the present paper, detailed investigation of twelve analytical models for predicting shear strength of exterior beam-column joint has been carried out. The study shows the effect of each governing parameter on joint shear strength predicted by various models. It has been observed that the consensus on effect of few of the governing parameters amongst the considered analytical models has not been attained. Moreover, the predicted joint strength by different models varies significantly. Further, the prediction of joint shear strength by these analytical models has also been compared with a set of 200 experimental results from the literature. It has been observed that none of the twelve models are capable of predicting joint shear strength with sufficient accuracy for the complete range of experimental results. The research community has to reconsider the effect of each parameters based on larger set of test results and new improved analytical models should be proposed.

PURPOSE: Stroke patients have reduced balance ability due to a lack of motion in the ankle joint. Elastic taping assists movement, and joint mobilization, a form of passive movement, enhances mobility. The purpose of this study was to determine the immediate effects on balance ability after anterior-to-posterior (A-P) talocrural joint mobilization combined with elastic taping in stroke patients. METHODS: Twenty stroke patients were divided into two groups: a joint mobilization with taping group (experimental group, n=10) and an elastic taping only group (control group, n=10). The experimental group underwent anteroposterior mobilization of the talus and elastic tape was applied to the calf and tibialis anterior muscles. The control group had elastic tape applied. Dynamic balanced abilities were assessed by using the BioRescue system. After 30 minutes of intervention, the forward, backward, left side, and right side sway areas ($mm^2$) were measured. RESULTS: Only the experimental group showed a significant increase in forward sway area after intervention. However, no significant differences were detected between the two groups. CONCLUSION: This study shows that A-P talocrural joint mobilization combined with elastic taping has a positive effect, producing an immediate increase in the forward balance ability of stroke patients. However, this study did not examine joint mobilization alone. In subsequent studies, it is necessary to examine the effect of joint mobilization only on balance in stroke patients.

This study focused on getting clear understanding on the legal bases in terms of plurality of obligors and plurality of obligees through a analysis the PICC(2010) which has been standing firmly as the general principles of international commercial contract. Related to the title of this paper, PICC are dealing with not only plurality of obligors but plurality of obligees. The contents of the former are as follows; presumption of joint and several obligations and obligee's rights against joint and several obligors (arts.11.1.1, 11.1.2, 11.1.3), availability of defences and rights of set-off and effect of performance and set-off (arts.11.1.4, 11.1.5), effect of release or settlement and effect of expiration or suspension of limitation period (arts.11.1.6, 11.1.7), effect of judgment (art.11.1.8), apportionment among joint and several obligors and extent of contributory claim (arts.11.1.9, 11.1.10), rights of the obligee, defences in contributory claims, inability to recover (arts.11.1.11, 11.1.12, 11.1.13) and so on. On the other hand the contents of the latter are as follows; definitions (art.11.2.1), effects of joint and several claims (art.11.1.2), availability of defences against joint and several obligees (art.11.2.3), allocation between joint and several obligees (art.11.1.4). The main subjects are one is when several obligors are bound by the same obligation towards an obligee, the obligations are joint and several when each obligor is bound for the whole obligation, the obligations are separate when each obligor is bound only for its share and the other is when several obligees can claim performance of the same obligation from an obligor, the claims are separate when each obligee can only claim its share, the claims are joint and several when each obligee can claim the whole performance and the claims are joint when all obligees have to claim performance together.

A robot arm with free joints has some advantages over conventional ones. A light weight and low power consumed arm can be made by a reduction of the number of joint actuators. And this arm can easily overcomes actuator failure due to unexpected accident. In general such underactuated arm does not have controllability because of the lack of joint actuators. The two-link arm with a free joint introduced in this paper is also uncontrollable in the sense of linear system theory. However, the linearized system sometimes can not represent the inherent dynamic behavior of the nonlinear system. In this paper the dynamic characteristics of the two-link arm with a free joint in view of global motion including damping and friction effect of the joints is investigated. In the case of considering only the damping effect, the controllable goal positions are confined to a specific trajectories. But in the case of considering the friction effect, the system can be controlled to arbitrary positions using the friction of the free joint as a holding brake. Also numerical example of position control is presented.
