문헌에 의하면 국제합작기업 파트너 특성이 합작기업성과에 미치는 영향에 대한 연구가 주로 부분적인 파트너 특성에 초점을 맞추고 있으며, 또한 파트너 특성과 합작기업성과의 관계에 대한 제휴몰입도의 매개효과 연구가 부족한 실정이다. 따라서 본 연구에서는 국제합작기업 파트너 간의 특성을 포괄적인 관점에서 CEO 리더십행동 유사성, 전략적 유사성, 자원적 유사성, 조직적 유사성 등으로 파악하고, 이들 특성이 제휴몰입도 및 합작기업성과에 미치는 영향에 대해 분석한다. 연구결과에 따르면 CEO 리더십행동 유사성과 조직적 유사성은 제휴몰입도 및 합작기업성과에 긍정적 영향을 미치는 반면, 전략적 유사성과 자원적 유사성은 제휴몰입도 및 합작기업성과에 부정적 영향을 미치는 것으로 나타났다. 또한 제휴몰입도는 합작기업성과에 긍정적 영향을 미치고, 파트너 특성과 합작기업성과의 관계를 매개하는 것으로 나타났다. 본 연구의 결과를 바탕으로 중요한 결론 및 시사점을 제시한다.

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.

Fiber Reinforced Polymer (FRP) bars have now been widely adopted as an alternative to traditional steel reinforcements in infrastructure and civil industries worldwide due variety of merits. This paper presents a numerical methodology to investigate FRP bar-reinforced beam-column joint behavior under quasi-static loading. The proposed numerical model is validated with test results considering load-deflection behavior, damage pattern at beam-column joint, and strain variation in reinforcements, wherein the results are in agreement. The numerical model is subsequently employed for parametric investigation to enhance the end-span beam-column joint performance using different joint reinforcement systems. To reduce the manufacturing issue of bend in the FRP bar, the headed FRP bar is employed in a beam-column joint, and performance was investigated at different column axial loads. Headed bar-reinforced beam-column joints show better performance as compared to beam-column joints having an L-bar in terms of concrete damage, load-carrying capacity, and joint shear strength. The applicability and efficiency of FRP bars at different story heights have also been investigated with varying column axial loads.

In complex waterproofing method, the stability of the joint is an important factor. The joints should not be broken for repeated movements and tensile forces. Therefore, we tried to confirm the stability of joints in newly developed joints and general joints. Repeated fatigue resistance performance tests and joint tensile strength tests were carried out on four types of joints. The fatigue resistance performance test showed no abnormality in all four types. It was confirmed that the newly developed top-down joint has higher stiffness than existing joints.

In today's e-business environment, it is important to make decisions cooperatively between companies on a supply chain for their business success. This research analyzes empirically the influences of organizational factors on joint decision making and the ones of the joint decision making on business performance. We collected 188 corporate-level data through a Web survey and tested them statistically through PLS method based on a structured equation modeling. The results showed that (i) partner's knowledge creation capabilities, inter-organizational process modularity, and inter-organizational trust had direct effects on joint decision making, (ii) joint decision making and electronic business interfaces bad direct impacts on business performance. Contrary to our expectation, however, the moderating effects of electronic business interfaces between corporations on the relationship between joint decision making and business performance was not significant. On the basis of these results, we discussed theoretical and managerial implications of the findings. The results are expected to provide useful perspectives when companies establish strategies to improve capabilities of cooperative decision making and business performance.

Majority of industrial robots are controlled by a simple independent joint control of joint actuators rather than complex controllers based on the nonlinear dynamic model of the robot manipulator. In this independent joint control scheme, the performance of actuator control is influenced significantly by the joint disturbance torques including gravity, Coriolis and centrifugal torques, which result in the trajectory tracking error in the joint control system. The control performance of a redundant manipulator under independent joint control can be improved by minimizing this joint disturbance torque in resolving the kinematic redundancy. A 3 DOF planar robot is studied as an example, and the dynamic programming method is used to find the globally optimal joint trajectory that minimize the joint disturbance torque over the entire motion. The resulting solution is compared with the solution obtained by the conventional joint torque minimization, and it is shown that joint disturbance can be reduced using the kinematic redundancy.

Both low-density parity-check (LDPC) codes and the multiple access technique of spatially coupling data transmission (SCDT) can be expressed in bipartite graphs. To improve the performance of iterative demodulation and decoding for SCDT, a novel joint sparse graph (JSG) with SCDT and LDPC codes is constructed. Based on the JSG, an approach for iterative joint demodulation and decoding by belief propagation (BP) is presented as an exploration of the flooding schedule, and based on BP, density evolution equations are derived to analyze the performance of the iterative receiver. To accelerate the convergence speed and reduce the complexity of joint demodulation and decoding, a novel serial schedule is proposed. Numerical results show that the joint demodulation and decoding for SCDT based on JSG can significantly improve the system's performance, while roughly half of the iterations can be saved by using the proposed serial schedule.

한국 전통 목조 건축물의 경우 구조적 성능은 재료 특성, 접합부의 형태, 치목의 정밀도 등에 따라 다르게 나타난다. 기존 사례 연구에서도 보와 기둥 접합부 형태는 변형 및 간격의 정도에 큰 영향을 미친다는 것을 보고하고 있다. 이는 단층 건물뿐만 아니라 대규모 다층 건물의 경우에도 마찬가지로 나타나고 있다. 따라서 본 연구에서는 접합부 형태에 대해 분석하고 모형을 제작하고 구조적 성능을 테스트하는 과정을 거쳤다. 그 결과, 주먹장맞춤의 실험체에서 최대 하중을 나타냈다. 각각의 형태의 접합부에 의한 구조적 성능을 종합하면, 도래걷이 주먹장맞춤이 가장 높은 성능을 나타내었으며, 다음으로 도래걷이 장부맞춤의 순으로 나타났다. 건물의 구조적 성능은 관통하는 보의 치목 형태와 기둥 내부의 접합부 형테에 따라 다르게 나타남을 알 수 있었으며, 이는 다층 건물의 신축 또는 복원을 위해 고려되어야하며 이후 계속 연구되어야 할것으로 사료된다.

PURPOSE: This study investigated the influence of a specific hip joint exercise program on the characteristics of chronic low back pain (LBP), hip joint range of motion (ROM), and performance level in amateur golfers with LBP. METHODS: The study included 28 adult male amateur golfers with LBP and reduced internal rotation (IR) of the lead side hip joint. Subjects were randomly assigned to an experimental (EG) (n=14) or control group (CG) (n=14). The Numerical Rating Scale score for pain, ROM of the hip joint and trunk rotation, performance parameters for golfing were evaluated. A specific exercise program designed to improve IR of the lead side hip joint was performed by the EG, but not the CG. Post-intervention evaluation was performed and the collected data were analyzed. RESULTS: After the intervention, the severity of LBP was significantly reduced (p<.05) and the IR ROM of the lead side hip joint was significantly increased (p<.01) in the EG. Moreover, the trunk rotation range was significantly increased in the EG (p<.01). The drive distance was significantly difference between the EG and CG (p<.05). CONCLUSION: A specific hip joint exercise program can help to reduce pain level and improve performance level in amateur golfers with LBP and increased IR ROM of the lead side hip joint. A significant increase in ROM of the lead side hip joint reduce LBP and was related to driving distance in the EG.
